Improved modularized steel connection structure

Abstract

The invention provides an improved modularized steel connection structure to solve the problems of low strength and complex installation of an existing steel structure, and belongs to the field of steel structures. The improved modularized steel connection structure comprises a plurality of T-shaped connection steel bars and connection frames. The connection steel bars comprise wing plates and webplates. The connection frames comprise connection plates and connection sleeves. The top ends of the connection sleeves are connected with the outer edges of the connection plates. The connection steel bars are arranged in a parallel mode. The connection frames are connected between the adjacent steel bars. Two sides of the web plates are correspondingly attached and fixed to the outer walls of the connection sleeves by fasteners. Each connection steel bar and the corresponding connection frames on two sides connect and form a cross beam with the I-shaped cross section. The outer wall of eachconnection sleeve corresponding to two corresponding adjacent connection frames on one side of corresponding web plate is fixed in an attaching mode by fasteners, and forms a T-shaped longitudinal beam which is perpendicular to the corresponding steel bar in the length direction and has the T-shaped cross section. The top faces of the connection plates of the connection frames are flush. The connection structure is high in strength and is convenient to install.

Description

technical field [0001] The invention belongs to the technical field of steel structures and relates to an improved modular steel connection structure. Background technique [0002] Steel structure engineering is a structure mainly made of steel, which is one of the main types of building structures. Steel is characterized by high strength, light weight, good overall rigidity, and strong deformation ability, so it is especially suitable for building long-span, ultra-high and ultra-heavy buildings. [0003] At present, in the construction process of large buildings, steel structural parts welded by multiple split parts are often used. The steel structural parts have problems such as labor-intensive and material-intensive processing and insufficient strength of the steel structural parts. . [0004] The existing application number is 201710185218.2, which is a Chinese invention patent application titled "A lap-joint steel structure and its manufacturing and installation metho...

Problems solved by technology

[0003] At present, in the construction process of large buildings, steel structural parts welded by multiple split parts are often used. The steel structural parts have problems such as labor-intensive and material-intensive processing and insufficient strength of the steel structural parts.

[0004] The existing application number is 201710185218.2, which is a Chinese invention patent application titled "A lap-joint steel structure and its manufacturing and installation method". It cuts and bends the middle part of the main connector of the I-shaped steel structure, and the I-shaped The ends of the auxiliary connectors of the steel structure are cut and bent, and then installed by lap joints. Although it can avoid the existence of more split parts resulting in low connection strength and excessive waste resulting in waste, it has the following problems question:

[0005] 1. There are still joints between the main connector and the auxiliary connector, so the joint is still a relatively fragile part, and because the middle part of the main connector needs to be cut and bent, it will further lead to the low strength of the main connector itself ;

[0006] 2. On-site installation is not only troublesome, but also through on-site cutting and bending, the construction is greatly affected by the on-site construction level
