1, in the construction process, found that the plate slit there are two main reasons: the first is a plate is not fully dry, after the installation, the board will automatically shrink is dry, so is the feeblest element in the tensile - plate and plate column, beam, plate and wall board or the junction of the roof.Also, if cement dispensing glue mucilage used cement mark, label and GRC plate and easy to stick on it two inconsistent shrinkage performance of cement and cause cracking.Before construction, therefore, must choose to fully dry light GRC plate and varieties, with light GRC plate type adhesive latex cement with label.
2, GRC plate of bedding face, use besmear brushs SN - 1 before rendering method of interface agent, can't afford to ensure plastering mortar shell empty drum, the shell will form cracks after empty drum, long after will fall off.Interface agent, also known as binder, the ratio of the foregoing, besmear brushs the thickness of the interfacial agent about 1.5 -- 2.5 mm.
3, in order to guarantee the GRC lightweight partition board stiffness, especially in the case of large floor height, with steel nets along the vertical and horizontal directions with long book machine screw connection into the board, spacing for two-way @ 250.Bar at the top and side wall part connecting concrete column, with "L" shape additional steel after post, strengthen the joint strength, this is to avoid the plate between the article and the column plate and concrete wall joint cracking between effective measures.
Above is today about measures to prevent light wall plate slit method of all content, thank you for your patience to read.
