Secondary connector for construction installation and construction installation structure

Abstract

The invention provides a secondary connector for construction installation and a construction installation structure. The secondary connector comprises a first installation plate and a second installation plate which are configured to form a right angle. The secondary connector is characterized in that connecting slot holes are formed in both the first installation plate and the second installation plate; a circle of inner teeth is arranged along the wall of each connecting slot hole, and antislip concave-convex positioning structures are arranged at compressed positions, which correspond to fasteners, of the peripheral surfaces of orifices of the connecting slot holes. The secondary connector and the construction installation structure have the advantages that the secondary connector and the construction installation structure are simple in structure, installation and connection positions can be adjusted, deviation due to errors or position adjustment in a construction installation system is offset, the secondary connector can have position relations with the fasteners and can be closely connected with the fasteners, welding operation is omitted while looseness of connection among the secondary connector and the fasteners is prevented, the secondary connector can be permanently and firmly connected with the fasteners, the installation safety is improved, installation labor can be saved, and the installation cost can be lowered. The invention further provides a fire prevention and heat resisting solution for the connection structure. The fire prevention and heat resisting solution can be applied to various fire prevention zones.

Description

technical field [0001] The invention relates to a secondary connector for building installation and a building installation structure, which is mainly suitable for various products with higher requirements on earthquake resistance and precision. It is especially suitable for the use of curtain walls of building envelopes with high requirements for anti-vibration, anti-slip, and anti-loosening. The secondary connectors refer to connectors that are not directly connected to concrete. Background technique [0002] At present, the anchor bolts used in the curtain wall of the building envelope are affected by hundreds of thousands of wind waves and thermal expansion and contraction every year, which will cause the anchors to loosen and the gap between the connecting holes to sag, resulting in accidents. Therefore, in order to prevent the bolts from loosening and the gap between the connecting holes from sagging, the national regulations require that the screw, gasket, nut and th...

[0002] At present, the anchor bolts used in the curtain wall of the building envelope are affected by external forces such as hundreds of thousands of wind waves and thermal expansion and contraction every year, which will cause the anchors to loosen and the gap between the connecting holes to sag, resulting in accidents.

Therefore, in order to prevent the bolts from loosening and the gap between the connecting holes from sagging, the national regulations require that the screw, gasket, nut and the connecting anchor plate be welded to death. However, this welding on the construction site is not only difficult, but also exists Potential safety hazards of desoldering caused by welding on several different materials
