L-shaped outer rib ring plate joint used for connection of steel pipe concrete column and H-shaped steel beams

Abstract

The invention discloses an L-shaped outer rib ring plate joint used for connection of a steel pipe concrete column and H-shaped steel beams. The L-shaped outer rib ring plate joint comprises four brackets which are fixed to the four side faces of the rectangular steel pipe concrete column in a welded manner correspondingly so as to be used for being connected with the positions of the H-shaped steel beams; the upper flange and the lower flange of every two adjacent brackets are fixedly connected through one angle steel attaching plate, and the angle steel attaching plates are fixed to the rectangular steel pipe concrete column in a welded manner. The four H-shaped steel beams are connected to the corresponding positions of the rectangular steel pipe concrete column through the corresponding brackets. By means of the L-shaped outer rib ring plate joint, an original outwards-protruding plate becomes angle steel which can well conform to the outer contour of the joint by changing the manner of a horizontal rib plate, the requirement for a weld joint is met, a large outer ring plate is not needed, and too large protruding corners cannot be generated in a room; and on the other hand, the angle steel can better transmit force so that the force transmission path can be more definite, and the strength of the joint can be ensured to the maximum degree.

Description

technical field [0001] The invention relates to a connecting structure for connecting a steel pipe concrete column and an H-shaped steel beam. In particular, it relates to an L-shaped outer rib ring plate joint used for connecting a steel pipe concrete column and an H-shaped steel beam. Background technique [0002] The frame structure is a very popular structure in the current construction field, and the stability of the nodes in the frame is the most important thing. Commonly used joint forms in frame structures, according to my country's "Technical Regulations for Rectangular Steel Tube Concrete Structures" (CECS159:2004), commonly used joint forms include outer ring plate joints, inner diaphragm joints, and diaphragm through joints. However, although the outer ring plate joint can guarantee the strength of the joint at this stage, a horizontal ring plate with a large protrusion needs to be welded. On the one hand, it will increase the amount of steel used, and it will a...

Problems solved by technology

However, although the outer ring plate joint can guarantee the strength of the joint at this stage, it needs to weld a horizontal ring plate with a large protrusion. On the one hand, it will increase the amount of steel used, and it will also cause indoor convex corners, which will affect the aesthetics of the building. Indoor Area Utilization Rate
