How to make a roof ridge - recommendations from roofers. How to make a roof ridge with your own hands: a detailed analysis of the specifics and technologies Video examples of construction work

This homemade product is very cool and I think almost everyone who has extra Chinese motor gearboxes can do it. Of course, there is not much practical benefit from such a homemade product, but with its help, you can entertain a child, and generally entertain yourself in a boring time. In short, today we will consider a simple way to make electric platforms for moving on a flat surface. I think that this homemade product will seem at least a little interesting to many. Personally, I really liked her.

Well, homemade is very interesting, so let's not delay with a long preface, let's go!

And so, in order to make such electric "roller skates" we need:
- ten Chinese motor reducers
- board for charging lithium-ion batteries type 18650 (BMS S2)
- 18650 type batteries (8 pieces in total will be needed)
- two plastic boxes for four 18650 batteries each
- not very thick plywood
-powerful resistor 1 ohm, 5 watts
- socket type "mother" for the classic connector of the twelve-volt power supply
- power on/off button
- Velcro tapes
- one wheel for each geared motor
- wires of red and black color, so as not to get confused
- strong metal plate 1 mm thick
- bolts, nuts and washers according to the diameter of the drill that you will use
-special connectors of contacts, under the size of contacts of the switch
- 12 V power supply for battery charging

Of the tools you will also need:
- hot glue
- soldering iron
- screwdriver or eclectic drill
- metal scissors
-electric jigsaw
-pencil
-ruler
-marker
- heat shrink
- cans of paint for metal

The first step is to draw on a piece of paper the entire wiring diagram in the constitution. The author of the homemade product kindly showed the diagram of the entire device, so there should not be any problems.

And so, then we take a pencil, a ruler and a plywood sheet. Then we draw on the sheet an even rectangle with sides of eighteen and thirty-eight centimeters. The resulting rectangle is cut out using an electric jigsaw. Everything should turn out smoothly. If necessary, sand the edges of the workpiece a little with ordinary fine sandpaper, it will help remove chips and splinters from the edges.

Now, with the help of the same ruler and pencil, we make markings for gear motors on both longest sides of the workpiece:

We take a screwdriver and a drill with a diameter like that of the bolts with which we will fasten the metal plate. We drill equal through holes in the marks made earlier. Everything should turn out as in the photo below. That is, four holes on each side parallel to each other and one more small hole next to the extreme hole on one side, everything is clearly shown in the photo.
We take the motors and with the help of thermal glue, glue them well to the plywood blank. On each side, you need to glue five gear motors, parallel to each other:

Now take a box for connecting 18650 batteries and glue it, as shown in the photo below. It should be located between both rows of motors, closer to the back of the constitution.

Then you need to take wires, a battery charging module, a connector for a power supply, connectors, a switch and a 1 ohm resistor. After that, we begin to solder all the electronic components into one electrical circuit, doing everything exactly according to the scheme that is at the beginning of the article. It is necessary to solder carefully so that everything is clear and even. We place the battery charging module closer to the batteries themselves in order to avoid large losses due to resistance, glue the resistor next to the socket for the power supply, and glue the socket itself on the front of the structure, exactly in the center. What does the socket need to be glued so that it is convenient to connect the power supply for charging. The switch should be connected to long wires, the length of these wires should be sufficient so that when you stand on this platform, you can safely hold the switch in your hand and control it, and the wires would not get in the way, dangling under your feet. Of course, as for me, the control of the entire structure could be made wireless by adding a couple of arduinos and special wireless control modules specifically for them, but yes, this homemade product would cost more and make it more difficult, and the delay with wires is much less than wireless. Yes, and there are fewer failures.

In short, everything must be glued in the same way as in the photo below:

We install the wheels on the axis of the gearboxes. Since these wheels are designed specifically for these gearboxes, they should immediately sit well and tightly on them. But if suddenly they will easily climb off and hang out on the motor axis, then either immediately change the wheel to another one, or glue it firmly, because it’s better not to risk it:

We insert charged batteries into the box and test the installation.

If, when the switch is turned on, all the motors begin to rotate the wheels in one direction, and the wagon starts to drive smoothly, and when it is turned off, it naturally stops moving, then everything is done correctly. If one or more motors rotate in the wrong direction, then you just need to solder the wires on this motor, that is, swap the red and black wires:

We take a metal sheet one millimeter thick and a ruler with a marker. Then we draw another rectangle with sides of eighteen and thirty-eight centimeters. Then cut out with metal scissors. But when cutting, be very careful and do not forget about safety!

In this workpiece, it is also necessary to drill eight identical holes parallel to each other. These holes should match the holes on the plywood blank that was made earlier.

Then we put the metal blank on an unnecessary cardboard or plywood and cover it with a layer of paint (the author used gray and, as for me, it looks pretty good). It is necessary to do painting in a well-ventilated place, and preferably on the street. And it is necessary to work in a respirator and preferably in protective glasses:

We cover the overall structure with a metal blank and make adjustments so that all the holes coincide with each other.
Then we take the bolts, nuts and washers and connect both parts together as shown in the photo below. As you can see, the metal sheet must be in contact with the gearmotors:

We take Velcro tapes and use them to make fastenings for the legs on the metal part of the structure.
By the way, you can replace that the wires from the switch must pass through an additional hole on one side of the plywood plate:

Now you need to make a second, exactly the same design as the first, but you do not need to connect your switch to it. The second design must be connected to the first switch, thereby making a common control button. Both constructs should work the same way.

Also, all joints must be insulated with heat shrink or electrical tape:

Well that's all! Simple electric "roller skates" are ready and it remains only to test them. To do this, first we charge both constitutions. And then we stand on them and attach the feet to the structures with the help of Velcro fasteners. It is necessary to stand evenly and accurately on the structures. Then we pick up the control button and start driving!

Of course, the speed is not very high, but for entertainment and leisure, such a homemade product is perfect. Of course, it was possible to add several diodes to the overall design scheme, but it works without them. Also, it would be possible to add a small LED backlight, it would be cool. But this homemade product is very cool without it.

When riding, you must follow safety precautions!

The final stage of building a house is the installation of a roof. Performing it, you have to decide how to make a skate on the roof with your own hands. In order to properly carry out installation work on installing the ridge, it is required to study the structure of the element and the sequence of construction work.

In order to properly carry out installation work on installing the ridge, it is required to study the structure of the element and the sequence of construction work.

The subtleties of installing a skate

The ridge is the upper rib located horizontally on the roof. It is formed by slopes and elements of ribs.

Before starting work, it is necessary to distinguish between a roof ridge and a roof ridge. The first is the junction of the roof slopes. This element can be made by various methods, for example, by laying bars on vertically arranged racks. The roof ridge is a special element, the choice of which depends on the type of material for the manufacture of the coating.

You can make a roof ridge with your own hands from any materials, different sizes and shapes. It is used to improve roof ventilation and remove excess moisture that accumulates on the inside of the slope.

There are many ways to make a ridge element for a roof:

Buy a ready-made version. The most difficult thing in this case is to choose a model of the desired shape (conical, figured, semicircular, etc.) and at the best price. You can pick up not only ready-made products for metal tiles, but also a special skate for ondulin sheets and shingles.
Order from a specialist. Making a skate does not require complex tools and a lot of time, so the finished product can be received in a few days.
Make your own. The main difficulty is deciding how to bend the metal sheet.

The most convenient option is to buy a ready-made skate. In this case, you do not have to bend the sheet yourself, mark and cut the material. The main task is to raise it to the roof and carry out the installation of the ridge.

Types of ridge element and its calculation

Roof ridges differ in several important ways.

In form, such elements distinguish between simple and curly.

The desired type of ridge depends on the design features of the roof and the personal aesthetic ideas of the owner of the house.

For the manufacture of the ridge element, the same material is most often used as for the roof:

Roll materials. In the case of using this material, the installation process will be the easiest. Wide strips (1 m) are cut out of the material, the length of which is usually 2 m. The strips are laid on the roof and fixed in the same way as the rest of the material.
Ceramic tiles are often used to cover the roof. In this case, you need to keep in mind that parts for a skate made of this material can be found on sale. They are fixed with wire and special solutions.
Metal. Currently, galvanized iron is commonly used. Roofing iron is not so popular. When buying metal to cover the roof, it is better to immediately purchase elements for the ridge of the desired length. Alternatively, you can try to make them yourself. Details are fixed on the roof with self-tapping screws.
Slate. For a roof made of this material, it is recommended to use ready-made skates. The roof structure in this case must be somewhat more complicated, which, in turn, complicates the installation process. The ridge is secured with staples.

Before you install the element, you need to correctly select its height. The coefficients necessary for the calculation can be found in the building special tables. Its value depends on the level of the roof slope.

To calculate, you need to calculate the width of the building, then divide it by 2 and multiply by the coefficient obtained from the construction table. This figure will indicate the required height.

For example, if the width of the building is 8 meters, and the slope angle is 45 ° (the coefficient according to the table is 1.0), then the height of the ridge will be 8/2 x 1.0 = 4. In this example, the top point of the ridge element will rise above roof surface by 4 m.

Making a roof ridge

The manufacture of this element does not require special knowledge, so the sequence of work is given below.

First, a metal sheet is laid on a work surface and markings are applied. Usually such a sheet is enough for the manufacture of 1 to 3 blanks. Then the sheet is cut according to the markup into strips of the required width. It is best to use a special tool for cutting - a cutter, which will make the edges smooth and work faster.

Then the blanks are again laid on the surface and mark the central part and edges. In the presence of a roll forming machine, metal bending is carried out with its help. After working on the machine, a finished ridge for the roof is formed.

Often, metal shears are used instead of a cutter. With them, the sheet is cut by 0.5-1 cm and folded using a machine. Then they move on to bending the next workpiece.

This operation is best done by two people. In this case, it will take no more than 10 minutes to make a roof ridge with your own hands from 3 blanks. If it is possible to use an automatic machine, then the operating time can be significantly reduced.

You can bend the beam in another way, without using a machine. To do this, you need to prepare a beam of a suitable size and bend the sheet on it with a mallet. The latter should be made of rubber or wood to prevent damage to the protective layer.

The roof, which is covered with metal tiles, will include both the main coating and some additional elements. It is desirable to install the main ones correctly, but you can do without them. There are also obligatory elements, for example, a skate. It is an integral part of the roofing system. This article will discuss how to do it yourself, avoiding the most common mistakes.

If installed incorrectly, the roof will not be able to fulfill its main function - to protect the entire building and the roof from the negative effects of various climatic and weather conditions.

An important condition for laying metal tiles is good ventilation. To ensure good ventilation, you will need to install the roof base in such a way that air circulates from the ridge to the eaves.

If there is a suspicion that the existing room will be exposed to dampness, better and more efficient ventilation of the metal roof should be taken care of.

Tip: when installing the base under the metal tile, you must not forget to provide and leave a gap (at least 50 mm to raise the crate). This measure is able to provide a ventilation gap between the underside of the roof and the insulating material. Do not neglect the installation of a seal under the ridge.

Scheme of the arrangement of the elements of the ridge: 1 - additional laths of the crate, 2 - hydro-barrier, 3 - metal tile, 4 - wind board, 5 - sealant of the ridge, 6 - plank of the ridge.

The ridge structure is able to provide ventilation and air outlet from the roof space from the same side. The ridge is the upper edge of the roof, which is a gable horizontal intersection of roof slopes. When viewing the device from the street, it is worth knowing that its outer angle is at least 190 degrees.

It is the uppermost part of the roof, where the ventilation gap is introduced. Therefore, ventilation of the entire space under the roof is carried out through it. The ridge is the first element of the roof, which will take the blow of the negative impact of climatic and weather factors, including gusts of wind. In this regard, it is not at all recommended to save on ridge fasteners.

The main existing types of skate

To date, roofing stores are ready to offer the following types of ridge:

Skate plank.
Mortise.
Semicircular.
Crossed.

The ridge strip, which is also called the ridge profile, is intended to close the places where two slopes on the ridge meet (in the upper part of the roof). This function is no less important in decorative terms.

Possible forms of straps for metal skates.

It should be borne in mind that modern manufacturers produce skates that are identical to the color of the metal tile. Consequently, such an element, when laid with your own hands, will harmoniously fit into the general appearance of the roof. Do not forget that a special sealant fastens the bottom of the ridge bar. The function of semi-circular skates is identical to the function of ridge bars. The only difference is that the semicircular ridge has a more attractive appearance.

Most often, a metal tile manufacturing company is engaged in the production of skates of various textures and colors, in strict accordance with the roofing material.

If you purchase all the roofing elements from the same manufacturer, you can at least get an attractive roofing. In the best case - a high quality coating and functionality.

Crossed and mortise skates are most often used to equip hip-type roofs. The very name of the mortise ridge indicates that such an element will need to be cut into the roof slope, while its horizontal level is always lower than the main one.

The valley is a joint element of the mortise ridge.

The crossed ridge has intersections, while they are always located horizontally. Therefore, they are quite often confused with the hips of the roof.

The main components of the ridge structure should be considered.

People who have chosen a metal tile as a roofing will need to purchase a ridge, a metal tile, accessories and necessary fasteners from one seller.

The main components that are needed in order to make a ridge structure are:

ridge ventilation bar;
lightning rod holder;
ventilation tape;
ridge seal;
sealant;
other air elements.

Such details will be able to help make the installation and fix it as correctly and reliably as possible, as well as ensure its high-quality functionality.

In this case, the design will not only protect the joints, but also provide a reliable level of ventilation.

Elements that will be needed in order to install the ridge structure with your own hands:

skate accessories;
rope or winch;
a bar with a section of 70x90 mm or more;
crate bars;
navigation bridges;
roofing material or a special sealant;
screws;
enamel.

How to do the installation of the skate with your own hands?

The owner of the house or cottage fixes the metal tile ridge only after all pitched surfaces are covered with roofing material.

Tip: it is necessary to raise the ridge piece elements to the top of the roof to the place where they will be laid using a rope or a winch.

It is important to know the fact that it is possible to ensure a convenient location in the process of laying metal tiles by attaching brackets to the central bar, on which special navigation bridges are suspended. Further, it is possible to move carefully and perform all work on the installation of roofing.

The owner of the house attaches the ridge beam to the central beam.

For more convenient fixing of the ridge beam, it is recommended to round its upper edge. This measure is able to provide a tighter fit of the ridge elements. In order to prevent the appearance of biological manifestations (fungus, mold and decay), the ridge beam should be upholstered with roofing material or a sealant that is specially designed for this, along the entire length. This measure will make it possible to extend the life of the ridge and the entire roof as a whole. It is important to note that all its elements must be made directly with screws to the ridge beam.

To prevent decay of the ridge bar, it is necessary to additionally paint with enamel or oil paint those places that were wrapped with roofing material.

Ridge coating allows you to form two skates laid on adjacent slopes. The owner attaches the main skate, which is long (you will need to lengthen it by 10 mm).

Other skates should be correctly installed in such a way that their expanded ends are located towards the gable.

The process of fixing the skate with your own hands

two holes are drilled on the flat side of the timber;
two holes are also drilled on the longitudinal axis of the hump of the bar.

It is important to know that the holes must be drilled so that on the lapels they pass through the crests of the waves of the metal tile. It is correct to start the installation of the ridge structure from one of its ends, while mounting it over the end strips. In the process of laying a flat ridge, it is imperative to dock all parts with an overlap of 10 cm (or more).

In the case of mounting a semicircular ridge, docking should be done only along the stamping lines.

Unlace your boot all the way, fold back the tongue, and slide your foot in. The heel should be pressed against the back of the shoe, and the tips of the toes should lightly touch the toe.

During lacing, increase the rigidity of the fixation from the bottom up. On the foot, you can not tighten the laces very much, but in the ankle area you will have to try: the ankle should be as stable as possible so that the leg does not dangle in the skate.

If you have too long ends, you can walk down again, tie a bow, and tuck the loops into the hooks too.

2. Get in the right position

Place your feet shoulder-width apart or slightly narrower, point your toes and knees clearly forward. Straighten your chest and lower your shoulders, pull in your stomach, check that there is no excess.

Spread your arms to the sides, bend your knees slightly and check how stable this pose is.

3. Learn to walk on ice

Before you master gliding, practice just walking on the ice as if on the ground. This will help you feel more confident and keep your balance.

Take the correct position, spread your arms to the sides and step from foot to foot several times. Then try to move forward in small steps.

To begin with, perform this movement, holding on to the side or the hand of a friend, and then learn to walk without support. Walk both forward and backward.

4. Learn to fall safely

When falling, it is important to shift your body weight to the side in time to land on your hip, and not on your back. Falls back onto your back are the most dangerous because you can't put your hands up and risk head injury.

Practice falling in place. Squat down and shift your body weight to the side, dropping onto one thigh. Extend your hands out in front of you, softening the fall.

Do not put your hands far forward, keep them close to the body. If you stretch out on the ice, other skaters can run over your toes.

5. Learn to stand up properly

First get on all fours, then put one skate on the ice. Leaning your hands on your knee, rise and substitute the other leg.

6. Try different slide options

There are a number of beginner drills out there, and you'd better master them all: the more practice on the ice, the more confident you'll feel.

Flashlights

This is a simple exercise that will allow you to slide without taking your feet off the ice.

Put your feet together, connect your heels and spread your socks - this is position V. Slightly bend your knees and spread your legs to the sides, describing a circle with your legs, and then bring them back together, turning your toes inward - to position A. After that, return your feet to position V and repeat all over again.

When you spread your legs to the sides, they slide on the ice on the outer ribs, and when you bring them together, on the inner ones.

Also practice moving "flashlights" back. Here you first turn your feet to position A, then describe a circle with your feet and find yourself in position V.

snake

Another lead-in exercise without taking your skates off the ice. First, try to snake back.

Put your feet together, bend your knees slightly, spread your arms to the sides and move them slightly forward so that they are in front of the body.

From this position, turn the toes of both feet and knees to the left, and the shoulders to the right. Then reverse the position.

During the movement, do not look at the ice, look ahead of you. A lowered head will provide an unnecessary tilt of the body, which will prevent you from performing a snake.

You can start this movement at the side to give yourself momentum, and actively move your arms, turning your body.

With the same snake, you can move forward, alternately turning both legs to the left, then to the right.

Sliding with one foot takeoff

It is time to move on to sliding with alternate right and left foot take-off.

Put your feet together, slightly bend your knees. Turn the toe of your right foot outward 45 degrees and push off the ice as you slide forward on your left foot. Then repeat the same with the other leg.

It is important that when pushing off, you move your foot not clearly back, but slightly to the side. Due to this, you rest against the ice with the inner edge of the skate and create a good push.

At first, you can substitute the second leg immediately after repulsion and ride on two. Then try to maintain balance a little longer, balancing on one leg and only then substituting the second for it.

Do not forget about the correct position: the shoulders and hips look forward, the stomach is pulled in, the arms are apart and slightly forward, the gaze is directed straight ahead.

7. Learn to slow down

There are three options for stopping traffic. Try them out and decide which is more convenient for you.

hockey

Turn both feet toes inward and spread them wider. In this case, the skates move to the inner ribs.

With one foot in front

Step one foot forward and turn it with the heel out so that the blade is on the inside edge across the motion.

T-stop

Turn the toe of the back foot outward and press the middle of the foot against the heel of the front foot, making the letter "T". Tilt your pelvis slightly forward.

8. Follow safety precautions

Here are a few rules to help you avoid harming yourself and other riders:

Move around in a counterclockwise direction. So that the skaters do not collide, the movement on the rink occurs in one direction.
At first, stay close to the side. So in which case you can grab onto it and not fall under the skates of the chasing skaters.
Don't look down. Firstly, it spoils your technique: your shoulders and chest fall after your head, and then it is more difficult to maintain balance. Secondly, you do not see what is happening around, and you can stick into other skaters.
If you are learning to move backward, periodically look over your shoulder to avoid bumping into other people.

Remember that everyone has different motor skills and coordination. One person will cut through the ice already at the end of the first lesson, the other will need several visits to the rink just to move away from the side and ride without support.

Give yourself time, start carefully and train more often, and soon skating will become as familiar and comfortable for you as walking.

Roof ridge - a rib formed at the meeting point of roof slopes. The technology of installation of roofing materials is such that this area remains open after completion of work.
A ridge connection without additional protection measures is like an open window for the penetration of moisture, cold air, small birds and insects, despite the fact that we are talking about only a 2-3 cm thick gap. This article will tell you how to make a roof ridge correctly.

Features of the ridge connection

The arrangement of the ridge connection is the last stage in the construction of the roof, however, its durability and reliability directly depend on this event. In order to make the ridge on the roof protected from moisture and wind with your own hands, you need to know the main tasks assigned to it:

Protection against moisture penetration. The section of the roof that is not protected by roofing material allows moisture to pass through, leading to decay and destruction of the truss system.
Ensuring air circulation. A properly installed roof ridge acts as a ventilation gap through which heated air saturated with water vapor escapes. In the absence of ventilation, water from the steam settles on the elements of the truss frame and the inner surface of the roofing material, leading to their premature deterioration.
Protection against penetration of small birds and insects. If you have not yet become a homeowner, but are only going to, then you will be surprised how often birds equip their nests in the roof, penetrating there through minor cracks, to say nothing of insects.
Giving a finished look. Among other things, the ridge plays the role of a decorative element that adorns the roof, giving it a finished elegant look. The aesthetic potential of do-it-yourself ridge profiles is limited, but purchased models delight with a variety of shapes and colors.

Note! Roofing craftsmen recommend purchasing a profile at the same time as the material for covering the slopes. To achieve an accurate hit in color, you should look for options from one manufacturer. Profiles for arranging a ridge connection are produced in the form of additional elements, the length of which is 2 m. To determine how many parts are needed, it is necessary to add 10-15% to the length of the roof along the eaves for overlap and fit.

Device and profile forms

The roof ridge is a profile made of galvanized metal, asbestos cement, and ceramics. There are three forms of such products: simple, oval and with a U-shaped rib:

If you have no experience in construction, then the most obvious option is to install a simple ridge beam. To make it, it is tedious to purchase a metal corner with a width of mounting shelves of 40-50 cm for better waterproofing.

Profile views

The choice of a profile for arranging a skate with your own hands is not based on aesthetic tastes, but on the practical tasks that it must perform. Therefore, ridge elements are selected depending on the material with which the roof is covered:

To make a roof ridge with your own hands, you should purchase a special ventilation tape, roofing material or a highly diffuse membrane for waterproofing, roofing screws, a screwdriver, and a construction stapler.

Mounting process

The quality of installation of the ridge profile directly affects the effectiveness of protection against moisture penetration and air circulation. To avoid a mistake, follow the following recommendations of roofing masters:

When laying the roofing, step back from the top of the slope a few centimeters so that an auxiliary bar is installed on the ridge beam, which increases the height of the ridge.
Using a strip of highly diffuse membrane, film or roofing material, hydrosolize the rib between the slopes. Fix the waterproofing layer with a stapler and silicone sealant.
Take the ventilation tape, remove the protective film from the adhesive side and stick it along the ridge on both slopes. It is necessary so that the air freely escapes from under the roof, ventilating the truss system, preventing it from rotting. To organize powerful forced ventilation, special plastic ridge aerators are used.
Start mounting the ridge profile from one of the ends of the house, moving it forward 2-3 cm beyond the roof. After placing the first profile segment, check that it lies flat and fix it with a screwdriver and roofing screws. The step between the screws is 30-40 cm.
Put the second part on the first one with an overlap of 7-10 cm, place it evenly and fix it. Continue mounting until you reach the other end of the roof. Move the last section of the roofing profile 2-3 cm beyond the roof. To fit and cut to size, use metal shears, a hacksaw or a grinder.
Insert special plugs into the end holes of the ridge profile, if they are supplied with the model you have chosen.

Note! In hardware stores, ridge profiles are available that are suitable for different angles of roof slopes. Therefore, when going for a part for decorating a skate, accurately determine the slope and consult with the seller if the part you like is right for you.
