Endurance plate installation method

endurance plate screw mounting method

1, screw or rivet hole when installation, plate hole diameter should be 50% larger than the diameter of a bolt or rivet and sheet for heat bilges cold shrink when produce displacement. Prohibit any direct the practice of opening at the same time retaining screw or rivet, unable to reserve space heat bilges cold shrink.

2, plank on the drilling, hole and the hole spacing shoulds not be too much, nor too small. Spacing is accumulated large, thermal expansion and the reserved space is not enough; Small spacing must be seriously limits the movement of the plates, causing stress concentration. If time allows thermal expansion to bend, can offset part of the stress.

3, usually on the plate drilling, hole spacing in 50 cm more appropriate, the distance of the hole and the edge of the plate above suggestion in 3 ~ 5 cm.

4, rivet head diameter should be 2 times larger than the shank diameter, and combined with the gasket or washers, avoid the local big damage of the pressure plate.

5, screws should not be screwed too tight, avoid fracturing plate, with a fixed sheet after allowing a slight displacement as well.
6。 Unfavorable use PVC gaskets or bituminous waterproof tape, because of their precipitation chemical additives may cause chemical etching of plank, lead to crack of plate surface, even burst.

7, cold bending processing, the bending part to avoid using screws. All the pore structure of neutral silicone sealant filled, in order to prevent the detergent into the sheet edge effect.

endurance plate embedded installation method

1, according to the situation of plate thickness, heat bilges cold shrink and support frameworks, pressure and wind pressure, snow load, etc. , set aside sufficient amount of embedded. Generally more than 25 mm plate edge into a fixed frame, and requires at least two reinforced rib installed on a fixed area, thermal expansion rate is 0. 065毫米/米。 0 c

2, according to local climate conditions, and installation of the temperature, board with board between thermal expansion reserved distance. Usually in the summer when installation, set aside the distance can be less; In winter, when installation set aside space to a bigger one. Embedded installation, plate length is too long, is not recommended because the longer the length, the greater the cumulative length of the thermal expansion.

3, installation is: at the end of the installation, plank can still slight displacement on the holder, without affecting the combination of filling material and the plate or support. Therefore requires a certain filling material adhesion and flexibility.
