207 no matter dry method and wet method of assembling assembly, regardless of horizontal, vertical and inclined installation.
In hollow sun plate installation project is extremely important in the edge of the fastening, must pay attention to the following two points: in the connection profiles or in framed with slot effective space should be set aside to plate the inflation and the load displacement.
Linear thermal expansion coefficient of hollow sun is 7 x 10 m/m.
K, that is, each temperature increase 1 ℃, 1 m * 1 m plate along the length direction of the expansion of 0.
075 mm, the user must according to the engineering location points of the four seasons temperature difference, calculate the installation clearance data: such as the northern area, high temperature of 40 ℃, zui zui to - low temperature
30 ℃, 1 m * 1 m plate installation reserved clearance of 0.
