Seamless connection system for assembled steel structure beam-column member and floor bearing plate and construction method

Abstract

The invention relates to a seamless connection system for an assembled steel structure beam-column member and a floor bearing plate and a construction method. The seamless connection system comprisesa prefabricated steel bar truss deck, a steel I-beam, an upper chord connecting reinforcement, a lower chord connecting reinforcement, additional reinforcements, a column-side connection profile steelpart and a profile steel column, wherein the steel I-beam is fixed to a lower part of the steel bar truss deck; the upper and lower chord connecting reinforcements are arranged on an upper part and alower part of the steel bar truss deck respectively; the additional reinforcements are arranged on the top and at the bottom of the steel bar truss deck respectively; the column-side connection profile steel part is connected with the steel bar truss deck; the profile steel column is welded together with the column-side connection profile steel part; the steel bar truss deck comprises a bottom die steel plate and a plurality of spatial steel bar trusses which are fixed to the bottom die steel plate at intervals; the spatial steel bar trusses comprise upper chord reinforcements, lower chord reinforcements and web member reinforcements; one upper chord reinforcement and two lower chord reinforcements are fixed by a plurality of web member reinforcements; the web member reinforcements are arranged along the widths of the spatial steel bar trusses at intervals; and the lower chord reinforcements extending along the longitudinal directions of the spatial steel bar trusses are arranged below two sides of the upper chord reinforcements respectively.

Description

technical field [0001] The invention relates to a seamless connection system and a construction method of an assembled steel structure beam-column member and a floor deck, and is applied in the technical field of construction. Background technique [0002] As known, the reinforced truss floor deck is to process the main part of the steel bars in the floor slab into a steel bar truss by using imported equipment in the factory, and connect the steel bar and formwork (galvanized steel plate) together through connectors to form an easy-to-detachable, detachable Energy-efficient combination template for reuse. Therefore, the steel truss floor deck system has been widely applied in engineering, and a batch of innovative patents have been produced. However, at present, the steel truss floor deck system is mainly used in conventional ordinary concrete structures, and its application span is small. The reliability of the joint structure is low, and with the development of the constr...

Therefore, the steel truss floor deck system has been widely applied in engineering, and a batch of innovative patents have been produced. However, at present, the steel truss floor deck system is mainly used in conventional ordinary concrete structures, and its application span is small. The reliability of the joint structure is low, and with the development of the construction industry, prefabricated steel structures have been widely used in large public buildings such as cultural palaces, gymnasiums, and museums. Therefore, how to develop a steel truss building suitable for prefabricated steel structures The bearing plate is particularly important; in addition, the joints of ordinary beam-column components are cut at the intersection edge of the reinforced truss floor bearing plate and the steel column, which may easily cause excessive gaps and cause grout leakage
