Connecting node of square steel pipe column, H-shaped steel beam and L-shaped ribbed plate

Abstract

The invention relates to a connecting node of a square steel pipe column, an H-shaped steel beam and an L-shaped ribbed plate. The node is simple in structure, convenient to construct and is free of affecting to pour concrete in the square steel pipe column. The connecting node comprises the square steel pipe column, the H-shaped steel beam and the L-shaped ribbed plate, wherein two limbs of the L-shaped ribbed plate are respectively in butted joint with the upper flange and the lower flange of the H-shaped steel beam and connected with a wall plate of the square steel pipe column. The width B of the flange of the H-shaped steel beam 1 is twice the sum of the lengths b1 of the limbs of the L-shaped ribbed plate in butted joint with the H-shaped steel beam 1. The square steel pipe column comprises a cold bending rectangular square steel pipe column and a hot rolled square column; and the H-shaped steel beam comprises an H-shaped hot rolled steel beam and an H-shaped welded steel beam. The connecting node of the square steel pipe column, the H-shaped steel beam and the L-shaped ribbed plate in the invention adopts a measure of additionally arranging stiffening ribs outside to replace inner partition plates, and the L-shaped ribbed plate can transfer tension and pressure of the flanges of the beam to the wall of the square steel pipe column, so that the deformation outside a plane of the node is increased. Meanwhile, the problem of construction difficulty in installing the inner partition plates can also be avoided.

Description

technical field [0001] The invention belongs to the field of building structural components, and is particularly suitable for connecting nodes between square steel pipe columns and H-shaped steel beams in multi-high-rise steel structures, and is particularly suitable for beam-column nodes with small cross-sections of square steel pipe columns and difficult installation of inner partitions. Background technique [0002] At present, the main forms of connection nodes between square steel pipe columns and H-shaped steel beams in my country are: inner diaphragm type, diaphragm through type and outer diaphragm type. Among them, the inner diaphragm type is suitable for square steel pipe columns with larger cross-sections, but it cannot be realized for square steel pipe columns with smaller cross-sections due to the limitation of welding space, and the existence of inner diaphragms affects concrete pouring. The diaphragm through-type joint requires the square steel pipe column to b...
