Cellular and solid polycarbonate for fastening
Monolithic polycarbonate is a dense, continuous semi-transparent layer, similar to glass. It is used as a glass in public places with a large crowd of people - hospitals, educational institutions, sports facilities. Most often it is used for the equipment of commercial pavilions.
Cellular - hollow layer, the content of which is represented by multilayered components, having hard edges. Used in subsidiary and agricultural buildings. They are covered with garden plots, greenhouses, greenhouses, flower greenhouses.
The fixing of polycarbonate, its technology depends on the purpose of the use of the structure, the scale of the installation and the scope of application.
Technique for fastening monolithic polycarbonate
Monolithic polycarbonate in its appearance and structure is similar to glass. Its attachment repeats the technique of attaching glass - special frameworks are used in which polycarbonate sheets are embedded, or certain fixing clips are used to fix the layers of material.
There are two types of fastening:
- Wet
- Dry
Wet fastening implies a set of actions: a polymeric putty is applied around the edges of the frame and the perimeter of the polycarbonate sheet, then the sheet is embedded in the frame. The joints are filled with hermetic means( in the composition of silicone).An alternative to the sealant is called rubber pads or profiled bases.
Dry fastening occurs solely on the basis of mechanical intervention. Profiles are used with the addition of rubber pads, profiled insulation. With these materials, polycarbonate layers are attached to threaded screws.
It's important to note! The two mentioned fixing methods must have gaps or openings for thermal expansion of the polycarbonate structure.
Monolithic polycarbonate fully fulfills its protective functions of roofing in greenhouses, hotbeds, plant greenhouses. Its installation is vertical and horizontal according to the level of the earth. Fastened with standard screws, screws, polycarbonate washers, nuts using a rubber seal. The distance fixing is 50 centimeters. From the end of the sheet it is necessary to retreat 2 centimeters. Holes for screwing in fixing materials are made with an electric drill or a drill, following the temperature of the sheet. Polycarbonate strata are mounted on a pre-prepared frame profile. Mount should not be too tight.
How to mount a cellular polycarbonate?
The most acceptable method of fixing cellular polycarbonate is a point method. Its feature is the use of self-tapping screws with thermowells, which provide waterproofing to the fastening, absence of cold broaches and damage to the sheet. The thermoworge consists of:
- Leg
- Sealing cover
- Washer
The leg consists of a plastic base and has a thickness of polycarbonate sheet. It is screwed into the hole of the sheet 0.2 centimeter more than the diameter of the washer. Mounted at a distance of 40 centimeters. Do not overly tighten the mount, which helps to crumple the polycarbonate sheet. The washer screw is screwed 4 centimeters beyond the edge of the sheet. When docking polycarbonate layers, their fixing takes place by building docking profiles, which are also used in the installation of panels. The profiles are divided into:
- detachable
- integral
In addition to the docking profiles, the mounting profiles of panel installations are distinguished in the places of deformation of the frame board. They attach a wall profile. Corner places are to be finished with angled profiled plates. The roof ridge is fastened with a ridge profile, which can be attached at angles corresponding to the structure of the roof and its inclination.
Additional tips for securing polycarbonate
Polycarbonate is sensitive to the effects of precipitation and temperature changes. To avoid deformation of the polycarbonate, it is required to leave thermal apertures in the places where the sheets contact the other parts of the structure. The smallest opening is 0.35 centimeters per meter of sheet length.
The honeycomb polycarbonate makes a marking of drilling holes in the center of the partitions and uses thermowells for sheet thicknesses of 0.4-1 cm. In case of a layer above this index, thermowells are not used.
