High-strength square tube beam and column connection structure and installation method thereof

Abstract

The invention provides a high-strength square tube beam and column connection structure and an installation method thereof, and belongs to the field of steel structures. The high-strength square tubebeam and column connection structure and the installation method thereof solve the problem of low connection strength of an existing beam and column. The high-strength square tube beam and column connection structure comprises a column body and a beam body, further comprises a main connection pipe and a secondary connection pipe, and further comprises connection steel of an I-shaped steel structure fixed in the beam body, wherein the column body comprises four column plates and the beam body comprises four beam plates; four main reinforcing pipes are arranged in the column body, and a main reinforcing pipe is fixed at the connection of every two connected column plates; main connection holes are formed in two of four column plates paralleled to each other correspondingly, and auxiliary connecting holes are formed in the other two parallel column plates; the main connection pipe and the secondary connection pipe respectively penetrate through the two main connection holes and the two auxiliary connecting holes, the main connection pipe is connected with the walls of the four main reinforcing pipes in sequence, and the secondary connection pipe is connected with the walls of the fourmain reinforcing pipes in sequence; the connection steel comprises two wing plates and a web plate, one end of the connection steel presses against the outer side surface of each column plate. The structure can improve the strength and the stability of beam and column connection.

Description

technical field [0001] The invention belongs to the technical field of steel structures, and relates to a high-strength square tube beam-column connection structure and an installation method thereof. Background technique [0002] In the existing steel structure that uses square tubes as beams and columns, and fixes the ends of the beams on the outside of the columns, generally in order to ensure the stability of the connection of the beams, it is necessary to fix the ends of the beams to the columns through connecting seats, and the connecting seats are generally located at The outside of the beam will not only affect the appearance of the connection between the beam and the column, but the connection seat generally includes a connecting plate made of multiple steel plates, which are fixed by welding, so the connection is more troublesome, and the connection between the end of the beam and the column is more difficult. Small, so that the stressed part of the column is easy ...
