GRC The line is used in building decoration materials. Because of its unique appearance and excellent quality, it stands out in the market. If the line of grc is improperly maintained or other reasons will lead to leakage, what is the cause of leakage?
Baotou GRC Causes of line leakage:
1. GRC line is damaged by repeated freeze-thaw cycles;
2. GRC line is filled with ceramsite concrete, and 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 high, and the drainage is not smooth, causing leakage; In addition, GRC line and ceramsite concrete cracks, ceramsite concrete gypsum layer is seriously damaged;
4. Atlas construction GRC line profile polymer mortar surface and waterproof coating that do not conform to the construction design; After Jinyuan District 29-12 tried to remove the external wall thermal insulation components, a conclusion was drawn through the irrigation test, and the main reason was analyzed for GRC line leakage.
On site GRC lines are mesh packing construction, putty layer construction and coating construction; Considering the actual situation on site, the third scheme is selected. Gate scaffold erection: the basic structure of mast, cross brace, connecting rod, hook scaffold or horizontal frame, lock arm and other components, and the horizontal stiffener, scissors, sweeping rod, sealing rod, base, wall, and main structure of the building are connected to the standardized steel scaffold.
