Externally-hung connecting device for prefabricated wallboard installation and prefabricated wallboard installation method

Abstract

The invention provides an externally-hung connecting device for prefabricated wallboard installation and a prefabricated wallboard installation method. The externally-hung connecting device comprisesan upper connecting assembly and a lower connecting assembly. The upper connecting assembly comprises a first anchor plate, a first threaded connecting rod, a first L-shaped connecting plate fixedly connected with a lower flange of an upper steel frame beam, a first heat insulation base plate and a first fixing nut. The first threaded connecting rod penetrates through the first L-shaped connectingplate and the first heat insulation base plate to be connected with a first fixing nut. The lower connecting assembly comprises a second anchor plate, a second threaded connecting rod, a second L-shaped connecting plate fixedly connected with a floor slab steel bar, a second heat insulation base plate and a second fixing nut. The second threaded connecting rod penetrates through the second L-shaped connecting plate and the second heat insulation base plate to be connected with the second fixing nut. The externally-hung connecting device can safely and reliably achieve fixed installation of aprefabricated wallboard, can achieve rapid installation on the premise that production standardization of the prefabricated wallboard is achieved, reduces the workload of construction site operation,and improves the construction efficiency and the installation quality.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to an external connection device for installing prefabricated wallboards and a method for installing prefabricated wallboards. Background technique [0002] The external self-insulation prefabricated large wall panel is different from the traditional enclosure structure. The biggest feature is the engineering prefabrication production, the quality is guaranteed; the construction speed is fast, the construction period is short, and the efficiency is high. This also puts forward higher requirements for the structure and structure of the external self-insulation prefabricated large wall panels. The common whole panel walls mostly use concrete sandwich panels. The concrete sandwich panels are composed of steel trusses passing through the insulation board to connect the inner and outer concrete panels. However, this sandwich panel has inner and outer panels. ...

AI Technical Summary

Problems solved by technology

The common whole panel walls mostly use concrete sandwich panels. The concrete sandwich panels are composed of steel trusses passing through the insulation board to connect the inner and outer concrete panels. However, this sandwich panel has inner and outer panels. Relative slip and local bending problems, and the thermal conductivity of steel truss is high, it is easy to form cold bridges, resulting in poor thermal insulation performance of wall panels

[0003] The more important problem is that the existing connection method between prefabricated wall panels and steel girders adopts the form of complete external hanging, which is very complicated to construct, which is not conducive to construction, and the complete external hanging of wall panels causes a large lateral bending moment, and the joints are affected. Power is complicated, not safe and reliable enough
