Description

Technical Field

[0001] The utility model relates to the technical field of building decoration, in particular to a hidden chemical anchor bolt post-embedded part. Background Art

[0002] As my country accelerates the upgrading and renovation of old urban areas and residential areas, there are more and more facade renovation projects in urban renovation projects. In facade renovation projects, chemical anchor post-embedded parts are often used to install cantilever structures.

[0003] The traditional chemical anchor post-embedded method is as follows Figure 1 The usual construction process is: drilling holes and inserting chemical anchor bolts

[0004] →Install the embedded plate→weld the cantilever steel beam. The traditional embedded chemical anchor bolts are exposed, which is not beautiful and needs secondary mounting. After installing the embedded plate, the cantilever steel beam is welded on the embedded plate. During welding, the temperature at the root of the cantilever beam is as high as more than 1,000 degrees. The high temperature is transmitted to the chemical anchor bolt, which can easily cause the adhesive of the chemical anchor bolt to fail, and then cause the anchor bolt's pull-out resistance and shear resistance to be reduced or failed, which is a safety hazard.

[0005] The Chinese utility model patent with announcement number CN203499065U and patent name of connection structure of curtain wall column and post-embedded part and curtain wall disclosed a connection structure of curtain wall column and post-embedded part and curtain wall on March 26, 2014.
