GRC GRC is a common construction method in the construction industry. We often use GRC decorative lines in construction. GRC lines have been used in building decoration materials because of their appearance and excellent quality. GRC lines stand out in the market, but if improper maintenance and other reasons will lead to water leakage, what is the reason? How about GRC line leakage?
Baotou GRC Causes of line water leakage:
1. GRC lines are damaged by repeated freeze-thaw cycles;
2. GRC ceramsite concrete filling line. The external wall is made of benzene plate, all of which are hydrophobic materials. The water entering the insulation cannot be evaporated or discharged as soon as possible, resulting in wall water.
3. There is no slope on the top of GRC line, and the drainage is not smooth. The slope is inevitable. The water level is too large, and the drainage is not smooth, which causes water leakage;
resolvent:
Scheme I: construct according to the original design drawings, and apply GRC polymer mortar plaster and waterproof coating on the top surface of the line;
Scheme II: removal of GRC lines, benzene plate pasting, mesh construction, putty layer construction, coating layer construction;
Scheme III: packing construction of GRC grid cloth, putty layer construction and paint layer construction on site; (There is no specific practice in the insulation drawing set) Considering the actual situation on site, the third scheme is selected. Erection of door scaffold: the basic structure is composed of door frame, cross support, connecting rod, scaffold board or horizontal frame, and lock arm, and then horizontal reinforcement bar, scissors support, sweeping bar, sealing bar, support, and base are set. The standardized steel pipe scaffold connecting wall components and the main structure of the building is used. Door frame, cross support, scaffold board, connecting rod, lock arm, horizontal frame, horizontal reinforcement bar, scissors support, sweeping rod, sealing rod, base, connecting wall parts, railing, handrail.
