Baotou GRC The connection methods of components installed on the building wall are as follows: connect the components with the wall through the connecting plate, that is, connect the components with the connecting plate by bolts, and then connect the connecting plate with the wall or the embedded parts on the wall by expansion bolts or welding.
Fix the component directly on the wall with expansion pin:
1. The bolt passes through the frame of the component to fix the component on the wall;
2. The stud is connected with the wall through the embedded parts on the component;
3. The components connecting the steel keel and the main structure of the building are installed on the steel keel.
Widgets can be glued to walls:
1. Components shall be installed on the main structure or wall of the building. If the wall is aerated concrete, light walls, such as hollow bricks, need to design a stable installation system. Both the connector and keel system need stable anti rust measures, and galvanized steel or stainless steel connection materials should be used.
2. The connection point between the component and the wall shall be kept a certain distance (more than 10cm) from the wall edge to prevent the expansion anchor from splitting the local wall or insufficient anchoring.
3. Various connectors, anchor bolts, keels and other connection methods need static calculation to meet the strength and stiffness requirements of components under weight, wind load, seismic load, dry and wet deformation and temperature deformation. The installation nodes of components need to adapt GRC In order to allow proper displacement to release the component, the large humidity deflection of the component.
4. Deformation caused by internal force is blocked. In general, the connection points of components are not allowed to be welded.
5. Use expansion bolts in concrete beams. When installing components on columns or wall panels, consider the situation that there are reinforcements at the drilling location, try to avoid or use long double hole plates, and adjust the drilling location.
