In the construction industry, the integrated nailing method and anchoring method technology are very mature. In different industries and different situations such as curtain walls, steel structures, subways, bridges, tunnels, various methods are widely used, but how to apply products efficiently And method This requires the selection of corresponding products and technologies.

Everyone knows that products made of chemical anchor bolts used in conjunction with fine carbon steel or stainless steel have strong anchoring force and high compressive strength. They can be used in conjunction with SHB-601 rebar planting glue to have a synergistic effect.

Secondly, the mechanical anchor bolt does not require any epoxy medium to achieve the anchoring effect, because it has the characteristics of high temperature resistance and weldability, and the tensile force can be improved by the mechanical anchor bolt key opening and the shear force generated by the anchor hole. It is widely used in key projects such as curtain walls and tunnels. For the use of shaped anchors for curtain walls, the requirements of the building structure load code should be understood, and the exposed rear anchors should have reliable anti-corrosion and fire prevention measures.

In addition, there are requirements for the construction of embedded parts of the curtain wall. Standard JGJ102-2003 Article 5.5 requires:

1. The main structure or structural members should be able to withstand the loads and effects transmitted by the curtain wall.

2. The design value of the anchoring bearing capacity between the connecting member and the main structure should be greater than the connecting member itself.

3. The glass curtain wall column and the main concrete structure should be connected by embedded parts. The embedded parts should be embedded during the construction of the main concrete structure, and the position of the embedded parts should be accurate; when the embedded parts are used unconditionally to connect, reliable Measures and determine its bearing capacity through tests.

In addition to these two points, there are related requirements and regulations that can be understood from the standards in this area. Now back to the topic, for the anchoring of building curtain walls, should I choose chemical anchors or mechanical anchors ? Both methods must be selected, the advantages and disadvantages of the scheme can be well selected, and then the choice can be made in combination with the actual situation.
