Bottom-through top-ring joint

Abstract

The invention discloses a bottom-through top-ring joint, comprising an H-shaped steel beam connected with a concrete-filled square steel tubular column and also comprising an upper outer ring plate welded to the concrete-filled square steel tubular column, lower through partitions and web connection plates; the web connection plates are arranged on the sidewall of the concrete-filled square steel tubular column; upper and lower flanges of the H-shaped steel beam are welded to the upper outer ring plate and the lower through partitions respectively; a web of the H-shaped steel beam is connected to the web connection plates through bolts, and the lower through partitions are passed through the concrete-filled square steel tubular column. The bottom-through top-ring joint has the advantages that the lower through partitions are passed through the joint at the lower beam flanges of the joint, a large upper outer ring plate is not required, and too large convex corners are never caused indoors; the upper outer ring plate is arranged at the upper beam flanges of the joint, the column is partitioned only once at the joint, stressing is reasonable, casting concrete is facilitated, and construction and manufacture are relatively simple; the upper outer ring plate at the upper portion can be cast in a concrete floor without protruding out.

Description

technical field [0001] The invention belongs to the technical field of engineering, and specifically relates to a link between the bottom and the top. Background technique [0002] Now in the steel frame structure or frame support structure, the beam-column joint is one of the most important parts. For commonly used H-shaped steel beams and square concrete-filled steel tube columns, according to my country's "Technical Regulations for Rectangular Concrete-filled Steel Tube Structures" (CECS 159:2004), commonly used joint forms include outer ring plate joints, inner diaphragm joints, and diaphragm through joints. The outer ring plate joint can guarantee the strength of the joint, but a sufficiently large horizontal ring plate needs to be welded. On the one hand, it will increase the amount of steel used, and there will be indoor convex corners, which will affect the aesthetics of the building and the utilization of the indoor area. The inner diaphragm joint can meet the requ...

AI Technical Summary

Problems solved by technology

The outer ring plate joint can ensure the strength of the joint, but a sufficiently large horizontal ring plate needs to be welded. On the one hand, it will increase the amount of steel used, and there will be indoor convex corners, which will affect the appearance of the building and the utilization rate of the indoor area.

The inner diaphragm joint can meet the requirements of rigid joints, but it is necessary to weld the beam flange and the inner diaphragm on both sides of the connection between the steel pipe column and the H-shaped steel beam. Brittle failure, and not easy to process

The force transmission of the partition through the joint is clear, which ensures the working performance of the joint and is easy to process, but it will separate the column twice at the upper and lower flanges of the beam
