Horse on the roof of corrugated board: device and features of fastening skating planks on a profile

For longevity and security when using corrugated board roofing, skating plank installation must be done correctly. Skating planks, also known as battens, are essential for supporting and fastening roofing components to the corrugated board surface below, such as metal sheets or tiles. This article examines the fundamentals of putting skating planks on a corrugated board roof, emphasizing the fastening mechanism and features.

Because of their strength and adaptability, corrugated board roofs are a popular option for a variety of structures, including commercial and residential buildings. To preserve the integrity of the roofing system, skating planks must be firmly fastened on these roofs, a procedure that demands close attention to detail. Usually constructed of metal or wood, skating planks are positioned horizontally over the corrugated board surface. Their main purpose is to give the final roofing materials a level and stable base to which they can be attached.

The technique used to fasten skating planks on corrugated board is essential to the roof’s overall stability and longevity. By using the proper screws or nails, these planks can be firmly fastened to the corrugated board. To distribute the weight of the roofing materials evenly and to stop any possible movement or shifting over time, the skating planks’ spacing and alignment need to be carefully planned.

The material compatibility of the device and the way skating planks are fastened on corrugated board roofs are important factors to take into account. To prevent corrosion or structural compromise, the fasteners used should be appropriate for the corrugated board material as well as the skating planks. Maintaining the strength and weather resistance of the roof also depends on making sure the fasteners go deep enough into the corrugated board without compromising its integrity.

All things considered, installing skating planks on a corrugated board roof involves meticulous preparation, exact execution, and close attention to detail. Roofers can guarantee a sturdy, weather-resistant roofing system that protects the structure below over time by being aware of the features and mechanism used to fasten skating planks.

Basic concepts about the skate

Roofing terminology can occasionally be confusing, particularly when terms refer to distinct concepts. This also applies to the term "horse," which can refer to either the aquatic component or the constructive portion of the roof.

The upper rib formed at the junction of slopes is known as the horse in relation to the roof. As a result, one horse is formed on a gable roof where there is one such intersection. There are already two skates on a four-scary. And even more on intricate multi-sized roofs.

The skate is sometimes referred to as a complete part that overlaps a useful roof skate (rib). The skate bar is another name for it. She can take on various forms and bridges the space between the slopes. For corrugated board, skates with a triangular, curved flat section are most frequently utilized.

Therefore, it is required to equip the rib of the intersection of slopes (constructive horse) and block it with the ridge bar in order to fully arrange the horse on the roof from the corrugated board.

Formation of the ridge rib

When adjacent slopes are present between the rafter legs, a skate rib is created. It is a line that goes through the highest points.

There are various methods to join the rafters in the skate:

  • VSTOK – when rafter legs at the connection place is cut at an angle corresponding to the angle of slope of the slopes. In case of fractions, the junction is knocked down and additionally connected by overlays – wooden or metal.
  • Eliping – the upper parts of the rafters are applied to each other and sewed with nails, bolts or studs.
  • Handing "Vertereva" – at the edges of the stop (in the places of conjugation), the recesses are cut off half the thickness of the beam. Then these recesses are applied to each other and connected by any through connection, for example, a bolt missed through both rafter legs.

The handicap method works well on the ridge run when combined with other mounts. Because of the cutouts created by the rafters, they can be "worn" on the skate. In this instance, the rafters can be mounted overlapping, travel with overlays, or be "unmarked" between one another.

Rafters can also be supported by the skate run; no cuts are required.

The horse is formed in accordance with the roof pie’s structure after the rafters are installed. The layers of corrugated board typically go as follows: crate, waterproofing, skate bar, rafter system.

Skate bar and its functions

The skate bar is a galvanized steel outer corner made up of several sections. Products are available with or without a colored polymer coating. Typically, the horse is chosen to match the color of the profiled sheet. As a result, the bar almost disappears after installation when it combines with a common coating.

The skate bar serves the following purposes since it overlaps the clearance in the roof’s constructive skate.

1. Protection of the undercarbon space

This is the primary purpose, and it is nearly hard to accomplish without a skate. Moisture that can enter the space between the slopes damages the entire rafter system, the crate, and causes metal to corrode. Therefore, the roof’s service life and thermal insulation qualities will drastically decline if this skate clearance is not overlapped.

2. Providing undercarbon ventilation

There are gaps (the height of the gap equals the height of the profile) between the bar’s sole and the corrugated board profile after it is laid. They serve as the exhaust holes in the ventilation system, through which air exits the undercarbon space. The holes in the cornices are where the air inflow occurs. Thus, constant air movement to ventilate the subcutaneous space is initiated in the presence of cracks in the skate and near the cornice overhangs. This is particularly crucial for roofs with insulation.

Some of the warm interior vapors still enter the sub-rosary space even with the presence of modern vapor barrier films, which are a necessary component of the roofing pie in the presence of insulation. Warm steam cools and condenses, or transforms into water droplets, when it comes into contact with the metal’s surface due to the temperature differential between the interior and exterior. It should ideally dry quickly to prevent damage to the roof. To achieve this, create an air flow from top to bottom in the under-wrapping area, from the skate’s holes to the cornice overhangs.

It is important to remember that moisture in the area beneath the wrapping is not always a result of a single condensation. The metal roofs of Professor and other buildings are not totally sealed. As a result, moisture can enter the material from the outside, such as during periods of intense wind and rain. However, well-planned ventilation also helps to dry out this moisture.

3. Decorative function

The horse completes the visual aspect of the roof by overlapping the space between the slopes. The ridge bar blends in with the profiled sheet coating, giving the impression that it is an organic extension of the roof.

When building a corrugated board roof, it’s important to pay close attention to the installation features and the device when fastening skating planks securely. This article examines useful techniques and factors to take into account when fastening skating planks to the profile, guaranteeing the roofing structure’s longevity and best possible performance."

Forms of the ridge bar

Roofs made of profiled sheet can be skated:

  • triangular (simple flat);
  • P-shaped (curly);
  • Round (semicircular).

The most basic detail is the triangular bar, which resembles a regular metal corner with hooked edges.

The P-shaped horse in this section has a fold on top of the letter P, creating a more intricate figure. The P-shaped ventilation "pocket" created by this bend aids in the skate’s end-to-end ventilation. On corrugated board, the figure horse appears more intriguing, but it uses more metal. Its price is therefore marginally higher.

For wave corrugated board, round skates are the most aesthetically pleasing option. They have a semicircular groove-like appearance with side shelves for fastening. mandate the use of side plugs with ventilation holes that are semicircular or conical in shape. When it comes to ventilation "pockets," round skates are larger than direct form strips. However, they are the most expensive, in part due to the requirement for plugs.

The ridge element is typically 2-3 meters long. They are gathered by overwhelming the entire length of the ridge rib during installation. The skate strip shelf is between 100 and 300 mm wide. The most practical width is between 150 and 200 mm, which lets you shield the most vulnerable area of most roofs from the elements.

Though they may not be very functional, narrow planks can look great on small roofs. The same strips, whose shelves are 300 mm wide, typically appear overly large. They are therefore used on entire roofs that are covered in highly corrugated corrugated board.

The use of the seal

Regretfully, air does not pass through ventilation gaps alone. Severe wind and rain can cause moisture to seep into a burden beneath the horse. Moreover, debris, dust, insects, and even birds (with a high profile) can fall into the gaps. This is particularly inherent in small-sloped roofing that has a gentle slope.

As a result, a porous material seal that can fill voids is installed in the space beneath the horse. They come in various varieties:

  • Universal seal – is a tape made of foam polyurethane foam, characterized by open porosity. One side of the tape is often made self -adhesive, which increases the convenience of working with it. According to manufacturers, the universal seal does not interfere with the normal ventilation of the ridge, but such a statement is debatable and the builders-practitioners are in doubt.
  • Profile seal – a curly tape made of foamed polyethylene, has a rigid structure with closed pores. Repeats the profile of corrugated board, so it completely fills the gap between the skate and the roof. In order not to block the ventilation in this way, holes are provided in the profile seal (they can be left closed if the ventilation of the underbuilding space is performed through spot skating or pitched aerators).
  • Self -expanding seal (psul) – tape supplied in rolls. It is made of polyurethane foam saturated with acrylic. Initially, the seal is in compressed form. Its expansion (up to 5 times!) occurs after the installation of the tape under the skate. One side of the tape is self -adhesive, has a protective strip, which is removed to the possibility of gluing to the installation site.

Installation of the skate for corrugated board

When the corrugated board laying is finished, the ridge bar installation process starts. Simultaneously, the corrugated board sheets should not extend 50–100 mm past the skating rib, or the roller at the intersection of slopes. This enables unrestricted air movement in the subcutaneous space and outside the skating area.

They mount one extra bar of the crate on the upper portion of both slopes in order to firmly secure the horse. They will provide support when the skating bar is fastened.

Make sure the line where the slopes meet (the rib) is even before attempting to fix the horse. Use a cord or a laser rangefinder to accomplish this. Small horizontal errors are allowed, but they must not account for more than 2% of the skate shelf’s width. For instance, if the horse is to be mounted on a shelf that is 200 mm wide and 2 m long, the maximum deviation allowed along the slopes’ crossing line is 0.02×200 = 40 mm.

The roof in such an area will be more likely to leak if we permit a larger disparity to exist. Put another way, they will have to remove or use the skate bar with wider shelves if noticeable abnormalities are found.

The process to install the skate is as follows:

  1. Work begins with one edge of the ridge rib, the direction of laying opposite to the movement of the prevailing winds.
  2. Mount the seal. As a rule, it is glued to the ridge bar, on the back of the shelves, at a distance of 3 cm from the edges. Иногда уплотнитель монтируют непосредственно на профлист, в районе конька.
  3. The skate elements are laid along the constructive skate of the roof (rib) with overlap 150-200 mm. Overlapping round skates is carried out along the stamping lines.
  4. The fastening of the elements is performed to the upper corrugation (wave or trapezoid) of corrugated board, passing the screws through the crate. Fastening step-300-400 mm. Self -tapping screws are driven at the ends of the shelves of the ridge bar, at a distance of a few centimeters from the edge.

Use roofing screws with a rubber sealing puck to secure the fastener. The screw length is determined by measuring the height of the profile of the chosen profile brand because the horse is fastened through the upper corrugation.

Where L1 is the length of the screw part immersed in the crate (about 2.5–3 cm); L2 is the thickness of the washer with a rubber gasket (about 4 mm); and H is the height of the wave (trapezoid) of the corrugated board.

Using nails to secure the skate is not advised because there is a chance that it will come loose from the roofing in a strong wind.

The skate’s components are laid out sequentially, up to the skate rib’s edge, to complete the task. When the installation is finished and the styling is verified to be even and correct, the roof’s skate node is deemed finished.

A corrugated board roof’s skating plank installation demands careful consideration of both practicality and visual appeal. Unlike flat surfaces, the corrugated profile of the roof creates a unique challenge that requires exacting techniques for fastening the skating planks.

First and foremost, selecting the appropriate materials for the task is vital. Choose premium skating planks that can withstand the weather over time and are strong and resilient. Make sure they fit the corrugated roof profile properly for a snug fit that improves the look and performance of the roof.

The technique used to fasten skating planks is crucial to guaranteeing their stability and durability. It’s crucial to use fasteners made specifically for corrugated boards. These fasteners are designed to firmly grasp the corrugated profile’s ridges, preventing movement and preserving the installation’s integrity.

Furthermore, using the right installation methods is essential. First, make sure the skating planks sit flush against the corrugations by carefully aligning them along the contours of the roof. Methodically fasten each plank, adhering to manufacturer instructions to ensure top performance and security.

Finally, keeping the roof’s structural integrity and extending the life of the skating planks require routine maintenance. Periodically examine the fastenings for indications of wear or loosening. As soon as possible, replace any damaged planks or fasteners to avoid future problems like leaks or structural damage.
