Roof guardrail: types and features
Any roof, even in a non-residential house, must be equipped with fences. This is especially true when people live downstairs. Sooner or later, the upper part will still be raised for various purposes, and then only the fencing structures will become the last barrier of unhappiness.
Here at Gold Coast Edge Protection we take care of protecting the edges of the roof to avoid any kind of falling accidents.
Ceilings go up for a variety of reasons. Someone sunbathes or examines the neighborhood. Someone is clearing the snow. Someone repairs the roof or installs something (disassembles) on top. In any case, security can only be guaranteed in accordance with established standards. Every formulation, every digit in the regulations is calculated very carefully, and their non-compliance can turn into extremely unpleasant consequences. Therefore, the height of 1200 mm surely prevents people of any height from accidentally falling, no matter how precarious their position is. (in every sense).
Enclosure structures are quite diverse. Thanks to the snow protector it is possible to prevent the collapse of thick layers of snow and ice. They are capable of killing or paralyzing someone, damaging cars and trees. Depending on the situation, such a system is mounted only in individual places or around the entire perimeter of the upper part of the building. Modern manufacturers have learned to make snow devices designed for secure attachment to a folded roof.
Using transition bridges, you can make the movement on the roof of the building the safest. When introducing the connecting elements into the design, increase the length of the bridges, while any additional details should not cause inconvenience. It is recommended to choose such models in which the angles of inclination vary depending on the situation.
Wall ladders are designed to:
- Solve the problem of safe upload;
- Assist in the implementation of a variety of steeplejack jobs;
- Facilitate the evacuation and penetration of rescue services inside the house in extreme situations.
Its features have a fence for flat and pitched roofs. It is easier to install a barrier for a flat roof, and qualified specialists perform this job very quickly and easily. It is more difficult to protect those on the sloping roof, the list of requirements grows significantly. A safety device on a gable must take into account a significant angle of slope, especially in the attic. And in the multi-core variant of the roof, the preventive measures are usually individual in nature and are calculated separately each time.
The main part of the roof enclosure structures are almost always metal shelves. They can be made both from tubes and from profile elements. Important: The test must be carried out on the ground before these parts are raised to the top. The diameter of the reinforcement used to create the cross bars of the structure should be 0.4 to 0.8 cm. Connecting elements (various angles and gouges) allow a barrier to be installed on all surfaces and tilted as required.
To join the design, use:
- Self tapping screws.
The normal roof has vertical barriers with a height of 0.6-0.9 m; This value allows you to rest against the barrier at the drop or the hips, or the waist, depending on height. The horizontal bars can be up to 290 cm long. These horizontal bars are connected to each other by couplings. Any metal part must be covered with an anti-corrosion coating that allows you not to fear the negative impact of weather conditions. Organising a parapet fence is much more difficult, but its protective and aesthetic properties are much higher.
Enclosure structures are capable of:
- Avoid falling off the roof of vacationers and workers;
- Prevent the rapid collapse of snow masses;
- Eliminate the collapse of beams, bricks, antennas and other objects;
- Improve the aesthetic properties of the ceiling.
The typical execution of the barrier is mainly aimed at ensuring safety. The decorative moments and the organization of the space are secondary.
The fence is installed in such cases:
- The total height of the building exceeds 10 m;
- The height to the eaves is 7-10 m, and the roof slope exceeds 6.8 degrees;
- Equipped flat roofs of any height are equipped;
- They are placed flush with the ceiling of the gallery, balconies and loggias;
- Open exterior stairs, ladders and platforms are displayed on the roof.
It is necessary around the perimeter as closely as possible to connect all the elements. It is strictly forbidden to use any defective structure or with broken welds. The situation is unacceptable when parts of the enclosure cross the fire escape or interfere in any way with its use. The height of the fire escape barriers themselves must be at least 300 mm. When testing, the required load is applied for not less than 120 seconds.
The non-operational roof fencing in accordance with the standards provides for the presence of transitional bridges and special stairs. It is impossible to predict when and where exactly people will appear. No matter how many floors, and whatever the absolute height in meters, you need to place barriers from 60 cm high. In this case, the space between the racks and the crossbars of the structure should be a maximum of 30 cm, otherwise it is recognised that it is not reliable.
For the exploded roof, the set of rules imposes even higher demands. The commissioning of buildings of any height is not allowed, where the barrier structures will be less than 1.1 m. Fences from metal profiles can be made in various variations, among which lattice screens are more widely used. In its manufacture it uses both ordinary steel and stainless steel. The apparent profitability of the first variant is depreciated by the low durability and the need to necessarily use an insulating mixture from climatic changes.
In most modern designs, such processing is already done in production, relieving customers of care and reducing the time required for installation. The roof of sandwich panels is protected in a special way: if you mount the barriers in the studs, the integrity of the cake will be broken. Therefore, it is recommended to use supports from a special sample, as they are much stronger for the base. The mounting bracket has holes in the top into which the system is attached that blocks the way of people to danger. Fixing barriers in reinforced concrete systems should be done with the help of hinged fasteners; They are recognised by experts as the most competent and reliable way to solve this problem.
If the building is covered with a folded roof, you will have to use several other methods. The best way to block access to the edge is to build tubes shaped or made of the same material as the main part of the roof. To improve the aesthetic quality of the fence, it helps to stain it with powder paints. To fix the elements use universal brackets attached to similar parts of the ceiling bolts. Two more types of supports will be needed: hat and staples.
