Compact type square pipe beam column node structure and installing method thereof

Abstract

The invention provides a compact type square pipe beam column node structure and an installing method thereof, belongs to the field of steel structures and solves the problem of low connecting strength of an existing beam column. The compact type square pipe beam column node structure comprises a column body, beam bodies, a node, a plurality of external threaded rods and a plurality of internal threaded rods, wherein the column body comprises four column plates; the beam body comprises four beam plates; the node is located on the column body and comprises a grouting box located at the inner side of the column body and connecting seats located at the inner sides of the end parts of the beam bodies; four connecting seats located on four beam bodies are respectively fixed to the outer side surfaces of the four column plates; the connecting seats are formed through integrated bending of long-stripped rectangular platy steel plates; the external threaded rods and the internal threaded rodsare respectively located in external pouring cavities and internal pouring cavities. The compact type square pipe beam column node structure provided by the invention is capable of improving the connecting strength and the stability of the beam column.

Description

technical field [0001] The invention belongs to the technical field of steel structures, and relates to a compact square tube beam-column node 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 outer side of the beam body will not only affect the appearance of the connection between the beam body and the column body, but also the connection seat generally includes a connecting plate made of multiple steel plates, which makes the connection more troublesome. The stress-bearing part of the body is easy to deform, so it is necessary to improve it. Contents of the invention [0003] The object of the pr...
