The U lock polycarbonate hollow sheet is durable and there is no risk of water leakage!
polycarbonate hollow sheet, also known as polycarbonate hollow board. Not only is it weather-resistant, light-weight, flame-retardant, sound insulation, light-transmitting, anti-ultraviolet, and impact-resistant, it also has the characteristics of non-glare, shatter-resistant, and thermal insulation that glass does not have. In the mid-1980s, it quickly entered the building decoration material market, and it was used in building canopy, daylighting, wall, interior decoration and other projects. It is currently a building material widely adopted internationally.
However, with the continuous rise of large-scale projects such as high-speed railway stations and stadiums, the requirements for the waterproof and wind resistance of the roof system continue to increase, and the original flat panels can no longer meet the requirements due to material and structural limitations. The emergence of the U-shaped lock polycarbonate hollow sheet perfectly solves the problems of thermal expansion and contraction of ordinary polycarbonate hollow sheet and the water seepage problem caused by improper operation during installation.
Eliminate structural forces
The U-shaped lock polycarbonate hollow sheet is made of a hollow board with a fixed board width formed by a mold. Both sides of the board protrude from the board surface with a 17mm vertical rib with a connecting buckle. The two boards are opposite, and the board seam is fixed on the roof purlin with a fixed angle On the board, use the connecting fasteners to fix the board. The plate and the fixed angle code, the plate and the connecting buckle are all connected by the preset movable buckle, and the length of the plate is not restricted. The thermal expansion and contraction of the plate due to temperature changes can be digested in the unit, eliminating internal stress and deformation The resulting damage and the risk of water leakage. At the same time, the locking connection limits the width deformation of the plate and changes its force.
The two upright waterproof locking edges of the U-shaped locking polycarbonate hollow sheet close the line from which water leaks from the seam to the seam. The fixed purlins and diversion grooves of the flat structure can be omitted to reduce the installation cost. At the same time, in order to further improve the waterproof effect and air-tight performance, an EPDM rubber sealing strip is installed between the vertical side shoulder of the plate and the connecting buckle to eliminate the hidden danger of horizontal drainage leakage of the plate during special molding. The waterproof design is coordinated with the overall design, combined with the establishment of suitable units, drainage directions, drainage angles, and drainage ditches to cooperate with each other to achieve the ideal waterproof effect.
Strong wind resistance
The U-shaped lock polycarbonate hollow sheet and the fixed corner code, the connection between the board and the connecting buckle adopts a unique internal and external double hook design. Because the polycarbonate hollow sheet has low compressive strength and easy to deform, the double hook design makes the polycarbonate hollow sheet and the fixed corner code and connect The buckles form a closed system that engages each other to improve the compression resistance of the joints of the plates and reduce deformation. At the same time, the double hook design is also the result of balancing design and process requirements. Using too many hooks will make mold processing and production difficult, and reduce production efficiency and yield.
On the whole, the U-shaped locking polycarbonate hollow sheet inherits the excellent lighting, heat insulation and high strength characteristics of the hollow panel, and is faster and firmer in installation, more convenient to maintain, and can withstand very high loads. It is a long-term project for various large-scale projects. Ideal for use. It is suitable for various places such as sports stadiums, railway station platforms, high-end agricultural greenhouses, ecological restaurants, subway entrances and exits, and industrial plants.
