Four methods for fixing hollow plates
Everyone knows that after hollow plates are produced, they are in the form of flat plates one by one, so many people use hollow plates to make them into the shape they want, which involves To production, install. Based on years of experience in the hollow board industry, the editor now tells you several methods for fixing hollow boards.
1. Screw fixation
When the screw or rivet is perforated and installed, the hole diameter of the plate must be 50% larger than the diameter of the bolt or rivet to prevent displacement of the plate when it expands and shrinks. . It is forbidden to open holes directly and fix screws or rivets at the same time, and it is impossible to reserve space for thermal expansion and contraction.
2. Embedded installation
According to the thickness of the plate, the thermal expansion and contraction conditions of the support frame, and the wind pressure, snow pressure load, etc., a sufficient amount of embedding is reserved. Generally, the edge of the plate extends more than 25mm into the fixed frame and requires at least two ribs to be installed in the fixed area. The thermal expansion rate is 0.065mm/m.0C.
3. Fittings installation
pvc plastic Edge strips, used to clamp the hollow board. ---H type: 4mm, 6mm, 8/10mm ---U type: 4mm, 6mm, 8/10mm. Generally, the side strips of these two models are fixed.
4. Glue or hot melt fixation
Spray glue or double-sided tape on the surface of the hollow board. Or fix the hollow board with hot melt glue.
