The PC board is resistant to weak acids. It is made of polycarbonate as the main component and adopts the co-extrusion technology CO-EXTRUSION. It shows that the PC board is resistant to neutral oil, not resistant to strong acid, not durable, and not resistant to alkali, and it needs to be coated with UV Just work. But with high temperature resistance and good lighting effect, PC sunshine board (also known as polycarbonate hollow board, glass capron board, PC hollow board) is processed by high-performance engineering plastics-polycarbonate (PC) resin It has the characteristics of high transparency, light weight, impact resistance, sound insulation, heat insulation, flame resistance, anti-aging, etc. It is a high-tech, excellent comprehensive performance, energy-saving and environmentally friendly plastic sheet, and it is currently widely used in the world. Building materials have advantages that other building decoration materials (such as glass, plexiglass, etc.) cannot match. After the is processed, the installation methods are as follows:
Step 1: Spring line: According to the elevation of the drawing, the size of the sun board ceiling position and the determined center line, the main frame position line of the sun board roof will pop up. Embedded parts: According to the position of the main frame of the sun board ceiling of the elevation control line, check whether the elevation of the upper surface of the back beam of the hole meets the design requirements. The size of the pre-embedded steel plate of the node detail map releases the expansion bolt position line, and then drills the hole to place the expansion bolt, installs the steel plate and fixes it with the expansion bolt. Then cast the center line of the main skeleton onto the embedded steel plate. Step 2: Install the main frame: According to the position line of the main frame of the roof of the pop-up polycarbonate sheet
, install the two ends first and then the middle part. The method: After assembling the main frame of 60mm×60mm×3mm square steel pipe (galvanized) on the roof, Place it on the position line by manpower, hang the vertical surface with a wire pendant, temporarily fix it in the middle, and then weld it with the embedded steel plate. After the main skeletons at both ends are installed, pull the three longitudinal wires at the middle and both sides of 1500mm height (measured from the two ends of the steel plate), and then install them one by one from one end to the other until they are all completed. Step 3: Install the secondary frame: After the main frame of the sun board ceiling is installed and fixed, install the sun board ceiling 60mm×60mm×3mm square steel secondary frame and adjust the position. After leveling, it is welded and fixed with the main frame. While installing the sunshine board, put the moisture-proof agent. Install the outer layer of sunshine board: According to the deepening design layout position, install the outer 20mm thick sunshine board of the suitable size. After installation, the edges, longitudinal seams and transverse seams of the sunshine board are in a line, as shown in Figure 4.3- 2. The screw spacing can be appropriately configured according to the thickness of the board. Too small or too large a spacing is not good. If the spacing is too small, sometimes it will cause stress due to being too tight, causing damage. If the spacing is too large, the PC board may be unstable. The size of the screw hole must take into account the difference between the PC sheets in summer and winter and the thermal expansion and contraction of the book night. Generally speaking, the screw hole diameter should be 2~4mm larger than the minimum screw diameter to reserve room for expansion.
