In curtain wall construction, the main keel is usually connected to the main body of the building using embedded parts. For lighter curtain walls such as metal curtain walls and glass curtain walls, the force requirements for embedded parts are relatively simple. However, for the heavy curtain walls such as stone curtain walls, the requirements for the embedded parts are relatively high. In many cases, it is impossible to meet the stress requirements of the embedded parts in the acceptance specification, which is also a problem that has always existed in the curtain wall engineering.
The main keel of the stone curtain wall mostly adopts about 6m of steel, which spans about 2 floors. According to the requirements of the acceptance specification of the stone curtain wall, there are 3 to 5 anchor points within 2 layers. The embedded parts are often made of 200mm x 300mm iron plates. Therefore, the embedded part itself cannot have much adjusted position value, which requires the construction position of the embedded part to be quite accurate. However, in the construction in recent years, people have tried to use the method of implanting embedded parts with chemical anchors to increase the embedded parts at the required positions to meet the requirements of the curtain wall for the embedded position.
Chemical anchors are widely popular because of their simple and quick construction and stable mechanical properties. However, there are still many people who don't know much about chemical anchors, so they often buy inappropriate products. In the anchoring design rear chemical anchor bolts, the Code for Loads of Building Structures stipulates that all exposed rear anchoring members should have reliable anti-corrosion and fire prevention measures.
We know that chemical anchor glass hoses are mainly composed of quartz sand and flowing liquids therein. Because the chemical reagents contained in the glass tube are flammable and explosive, and can not meet the fire protection regulations, many manufacturers have now produced inverted cone chemical anchor bolts with injection type planting glue for the stone curtain wall. Among them, the common specifications are Nanjing Mankate’s M12×160 inverted cone chemical anchor.
Because chemical anchors are currently more confusing in the domestic market, prices range from a few cents to more than ten yuan per set. We need to choose the appropriate chemical anchor according to different engineering projects. If you have any questions about chemical anchors, please call Nanjing Mankate Technical Consultant.
