Endurance board canopy screw installation method

Endurance panels are widely used, especially in construction engineering. The carport canopy can be seen everywhere. You also want to build a carport canopy. Today, Shanghai Jienai will introduce the endurance board canopy for everyone. Installation method for reference: (1) screw spacing, depending on the thickness of the plate, for proper configuration, the spacing is too small and too large. If the spacing is too small, sometimes it will cause stress due to too tight, causing damage; if the spacing is too large, the PC board can be fixed and unstable. For this purpose, the following spacing is recommended: A: plate thickness less than 3.0mm, spacing 10~20cm B: plate thickness 3.0mm or more, spacing 20~30cm C: if fixed by stripping, the spacing is 20~30cm Note: If used When the self-tapping screws directly fix the PC board, the larger the screw pitch, the less the board is damaged by stress. (2) The size of the screw hole must be considered for the difference between the thermal expansion and contraction of the PC board in summer and winter and the book night. In general, the screw hole diameter should be 2~4mm larger than the screw diameter to reserve the expansion space. (3) When the position of the screw hole is too close to the edge of the PC board, it is very easy to cause the board to break. Generally speaking, The position of the screw hole is more than 2.5 times the diameter of the screw hole from the edge of the PC board. For example, if the screw has a diameter of 4mm, the position of the screw hole should be at least 1cm away from the edge of the PC board. (4) Do not lock the screw too tightly, otherwise it will be deformed and stress. (5) It is better not to use self-tapping screws for the screws locked on the PC board, otherwise stress will be generated and the stress will increase as the thickness of the board increases.
