A new type of external wall panel node and its construction method

Abstract

The invention relates to the field of connecting devices of architectural structures, and discloses a node of a novel external wall panel, which comprises the external wall panel, a major structure beam and L-shaped connectors through which the external wall panel and the major structure beam are connected; each L-shaped connector comprises an L-shaped connecting plate, a support square steel tube and a round end plate, the L-shaped connecting plate comprises a long plate and a short plate which are orthogonal, a long round hole is formed in the short plate of the L-shaped connecting plate, one end of the support square steel tube is connected with the long plate of the L-shaped connecting plate, and the other end of the support square steel tube is connected with the round end plate; a concentrated bar-mat reinforcement and nylon strips are arranged inside the external wall panel, round holes are formed in the external wall panel, the concentrated bar-mat reinforcement is exposed in the round holes, the round end plates are fixedly connected with steel bars in the round holes, bolt bars are arranged on a frame structure beam, the L-shaped connectors are hung on the bolt bars through the long round hole in the short plate, and the bolt bars are strapped by the nylon strips. The invention has the advantages that the connection is safe and reliable, mounting is convenient, the construction period is effectively shortened, the node of the novel external wall panel also has good seismic performance, and the hot and cold bridge effect with the outside is solved.

Description

technical field [0001] The invention relates to the field of connection devices for building structures, in particular to a novel external wall board node and a construction method. Background technique [0002] In the process of promoting new urbanization, the implementation of construction industrialization is a step of great practical significance. Steel structure building is a recyclable building structure in the city. It is not only easy to realize industrial production and promote the development of building industrialization, but also can reduce the discharge of construction waste, improve construction efficiency, and improve building quality. my country's sufficient steel production provides a solid material foundation for the industrialization of steel structure buildings, and the large-scale promotion of steel structure buildings can not only effectively break the current situation of obvious excess domestic steel production capacity and the difficulties of constru...

Problems solved by technology

[0003] At present, my country's prefabricated building structures are mainly reinforced concrete structures, while prefabricated steel structure buildings are very few. A large part of the reason is that the supporting system of steel structure buildings is not perfect, and many component nodes cannot be quickly assembled and installed. Therefore, the construction period is not much reduced compared with the concrete structure

Existing external wall panels usually use hook bolts to connect the panels to the structure. Usually, holes are opened on the panel, and the hook bolts penetrate through the holes to complete the welding with the angle steel on the main structural beam. It is necessary to drill each panel on site. Holes, welded through-length angle steel, and welded hook bolts, the construction steps are relatively complicated, which slows down the construction progress and prolongs the construction period; at the same time, due to the existence of through hook bolts, the cold and hot bridge effect is difficult to avoid
