Baotou GRC Installation of window cover: GRC Cement components shall be installed along the outer wall of the window frame, and care shall be taken to avoid plastering at the fastening position of expansion bolts. When installing the vertical window sideline or column to the elevation of each floor, pay attention to adjusting the vertical error.
There are transverse members of steel frame in GRC. Before installation, fix the angle steel or angle steel on the wall with a steel framework as a welding point. When the section size of the component is more than 300 mm but less than 1000 mm (without steel skeleton), the position of the embedded parts shall be marked on the insulation layer, the angle grinder shall be used for insulation, the GRC cement component pre galvanized embedded parts shall be fastened with the wall with expansion bolts, and the joint shall be treated for corrosion prevention and repaired. For members with a section size of less than 300 mm, extend expansion bolts directly through the insulation layer and fix them on the wall. Pay attention to bolts.
Anchor length. The treatment of GRC closed parts such as parapet coping, window sill plate, and wall under the window shall be beautiful and waterproof, and shall be constructed strictly in accordance with the process (flashing is the responsibility of the civil construction unit). If the embedded parts are at the hollow brick position, the installation nodes shall be fixed by bolts through the wall or lengthening the angle steel on the upper and lower main structures. Joint treatment between GRC components: the joints on the surface of GRC cement components shall be flat and smooth. Fill the gaps with special repair materials and use real stone paint. Spray the component surface. GRC cleaning completion: cleaning completion is a process before project completion acceptance. Although the installation has been completed, in order to pursue the surface quality, this process should not be sloppy. Pay attention to the protection of finished products in the whole process, so as to enter the next step of surface spraying construction.
