Endurance board installation method Installation precautions for endurance board
Endurance plates (also known as PC plates, polycarbonates, solid plates, bullet-proof glass, cardron plates, plastic solid plates, polycarbonate plates, aviation perspective plates) are high-performance engineering plastics polycarbonate or poly-carbon - ---- Acid processing. It is an ultra-high strength material. How strong is it, and it is stronger than bulletproof glass! This is actually true. It is really based on live bullet firing as a test basis through ballistic test ballistic tests. The results of the tests have special significance for polycarbonate solid panels used for safe lighting materials. At this moment, this kind of material for the PC is looked at. Then, what is the installation method of the endurance board ? What are the precautions for installing the endurance board ? If you are interested in this aspect, may wish to follow me to understand the installation method of the endurance board and the installation precautions of the endurance board !
Endurance board specifications
The specifications of the endurance plate have certain strict requirements from length, width and thickness. The general thickness is 1.8mm--20mm. The length is not equal, usually 30m--50m. The width is 500mm--2000mm. The color is also changeable, common blue, brown, milky, special colors can also be customized. The standard is: thickness equal to 10mm, length equal to 40m, width equal to 1000mm.
Stamina boards generally have: light material, impact resistance, low cost, and cost-effective. It can be packaged and transported conveniently, which can greatly reduce the cost of shipping. The longest service life is one of its most notable features. Currently, the highest lifetime record in the market is 20 years, and all are still in use. In the environment of high temperature and low temperature, it will not be deformed, and it will not burn. Its ignition point needs to reach 500 degrees, and it can be extinguished voluntarily after leaving the fire. It will not produce toxic gases during the combustion process and will not contribute to the spread of fire. .
The endurance board also has the characteristics of being warm in winter and cool in summer, it has lower thermal conductivity than ordinary glass and plastic, and its own thermal conductivity is 4 times that of ordinary glass. It can save heat and reduce the loss of heat. It is an economic and environmental protection material. It can also effectively prevent the irradiation of ultraviolet rays. The supply layer on the surface can convert the ultraviolet rays into visible light. It has good photosynthesis for greenhouse crops, high light transmittance, durability and anti-frosting.
Endurance board installation method
1. Endurance plate screw installation method
(1) When the screw or rivet perforation is installed, the hole diameter of the opening of the plate must be 50% larger than the diameter of the bolt or rivet in order to prepare the plate for displacement during thermal expansion and contraction. It is forbidden to directly fix the screw or rivet at the same time, and it is impossible to reserve space for thermal expansion and contraction.
(2) The distance between the hole and the hole drilled in the plate should not be too large or too small. If the distance is large, the accumulated thermal expansion length is large, and the reserved space is not enough; a small distance will inevitably severely restrict the movement of the endurance plate, resulting in too much stress. If you allow the thermal expansion to bend outwards, you can offset some of the stress.
(3) Holes are usually drilled on the plate, and the distance between the holes is 50cm. The distance between the hole and the edge of the plate is recommended to be 3-5cm.
(4) The diameter of the head of the rivet should be 2 times larger than the diameter of the shank, and gaskets or washers should be added to avoid damaging the plates with large pressure generated locally.
(5) Screws should not be tightened too tightly to avoid fracturing of the plates. Allowing for slight displacement of the plate after fixing is preferable.
(6) It is not advisable to use PVC gaskets or waterproof tapes containing bituminous components because the chemical additives they precipitated will cause chemical corrosion to the plates, resulting in cracks and even cracks on the surface of the plates.
(7) When cold bending is performed, the bent portion should not be fixed by screws. All pores are filled with a neutral silicone structural sealant to prevent detergents from penetrating the edges and affecting plate use.
Endurance board installation notes:
(1) It is prohibited to make surface contact with undried cement surfaces and acids and alkalis;
(2) Prohibit contact with organic solvents and glues and paints made of them.
2. Endurance plate embedded installation method
(1) According to the thickness of the plate, the thermal expansion and contraction situation is different from the support frame, and the wind pressure, snow pressure load, etc., reserve sufficient embedded amount. The edge of the general plate extends into the fixed frame more than 25mm, and requires at least two ribs installed into the fixed area.
(2) According to the local climatic conditions and the temperature at the time of installation, determine the thermal expansion reserve distance between the plates. Usually, when installing in summer, the reserved distance can be less; when installing in winter, the reserved space is larger. Embedded installation, the length of the sheet is not recommended to be too long, because the longer the length, the greater the cumulative thermal expansion length.
(3) The requirement for installation is that, at the end of installation, the plate can still be slightly displaced on the support without affecting the combination of the filler material with the plate or the support. Therefore, the filler material requires a certain degree of adhesion and flexibility.
Endurance board installation notes:
(1) There are protective films on the front and back of the PC board. To keep the board surface smooth, do not damage the film until the installation is completed.
(2) All open holes in the sun board (hollow plate) should be sealed with a sealing tape before installation to prevent dust and insects from entering the board.
(3) During the installation, the protective film on the edge can be uncovered by about 50mm as required to prevent the protective film from being pressed under the bead. After the installation is completed, the protective film is torn off again.
(4) The PC board must be installed with the UV-protection label facing outward.
(5) During the installation process, the construction personnel cannot stand directly on the PC board, and it is best to stand on the springboard.
(6) After the construction is completed, the debris on the board should be cleaned.
Editor's summary: The above is the installation method of the endurance board, the introduction of the installation instructions of the endurance board, hope to help the friends who have this requirement!
