Connecting joint of staggered floor prefabricated bay window and steel structure and construction method

Abstract

The invention provides a connecting joint of a staggered floor prefabricated bay window and a steel structure. The connecting joint comprises a prefabricated bay window assembly, an adjustable connecting assembly and a steel beam component assembly. The prefabricated bay window assembly is formed by connecting a horizontal top-hung bridging piece, a horizontal bottom-hung bridging piece and a vertical middle connecting plate into a reinforced concrete prefabricated component, a bay window bracket is arranged on the vertical middle connecting plate, multiple bolt holes connected with the steel structure are formed in the bay window bracket, and an embedded steel plate for being connected with the steel structure is further arranged on the vertical middle connecting plate. An inclined grouting hole is formed in the vertical middle connecting plate, and the grouting hole is located below the bay window bracket. The staggered floor prefabricated bay window is connected with the steel structure through high-strength bolts and other connecting parts, mounting is convenient and rapid, and meanwhile the components are small in size, simple in structure and low in weight, and conform to the characteristic of light weight of a steel structure house.

Description

technical field

[0001] The invention relates to the technical field of prefabricated buildings, in particular to a connection node of a split-level prefabricated bay window and a steel structure and a construction method. Background technique

[0002] At present, in multi-storey and high-rise civil buildings, the pre-bay window panels of prefabricated concrete structure buildings are often prefabricated integrally with the outer wall panels. The components are heavy in weight, complex in structure, and low in utilization rate of formwork, which is unfavorable for construction and hoisting and needs to be improved. Therefore, reducing the weight of the bay window prefabricated components is the goal of the present invention. The invention provides a bay window structure protruding from the building facade, which is rarely used in domestic steel structure houses. Since there is no corresponding mature engineering experience that can be used for reference in China, when the pr...
