Fabricated building outer wall external corner joint

Abstract

The invention relates to the technical field of building wall manufacturing, in particular to a fabricated building outer wall external corner joint. The fabricated building outer wall external cornerjoint is provided with an external hanging wall, and characterized in that the external hanging wall is constituted by a corner wall and two mutually-perpendicular side edge walls which are connectedwith the adjacent sides of the corner wall; the corner wall is constituted by an insulation board, a transverse square pipe, vertical square pipes and a wallboard; the side edge walls are constitutedby insulation boards, transverse square pipes, electric wood boards and wallboards; right-angle connecting plates are arranged on the positions, on the two vertically-arrayed vertical square pipes onthe inner side of the corner wall, of the inner side of the wallboard; the right-angle connecting plates are connected with the vertical square pipes through bolts correspondingly and provided with corner supporting columns; and square steel is arranged on the surfaces of the corner supporting columns, and the outer side of the square steel is provided with the wallboards. The fabricated buildingouter wall external corner joint has the advantages of being simple in structure, low in energy consumption, convenient to produce in factories, quick in fabricating, not prone to cracking, good in waterproofing treatment effect, good in heat bridge partitioning effect and the like.

Description

technical field [0001] The invention relates to the technical field of building wall production, in particular to a prefabricated building exterior wall with simple structure, low energy consumption, convenient factory production, fast assembly, not easy to crack, good waterproof treatment effect, and good thermal bridge insulation effect Yang corner node. Background technique [0002] As we all know, in recent years, prefabricated steel structure energy-saving buildings have become an important development direction in the construction field, and it is also an important way to deal with increasingly stringent building energy-saving standards. In prefabricated steel structure energy-saving buildings, the energy-saving treatment of external corner joints is a major problem. At present, the conventional method to reduce the building energy consumption of external corner joints is to conduct insulation treatment on the outside of the wall, and use thin-plate plastering for exte...

Problems solved by technology

In prefabricated steel structure energy-saving buildings, the energy-saving treatment of external corner joints is a major problem. At present, the conventional method to reduce the building energy consumption of external corner joints is to conduct insulation treatment on the outside of the wall, and use thin-plate plastering for external wall insulation construction Although this method can reduce energy consumption to a certain extent, the construction is cumbersome, the thickness is large, and it is easy to crack, which is not conducive to waterproof treatment and factory production
