A slot-assembled steel pipe concrete column-steel beam connection node

Abstract

The invention discloses a clamping groove assembling type steel pipe concrete column-steel beam connecting joint which comprises steel pipe concrete columns, clamping grooves, end plates, clamps and steel beams. Four pairs of clamping grooves which are parallel to the column walls are welded on the walls of the joint core zone steel pipe concrete columns, end plates which are parallel to the clamping grooves and are provided with the steel beams in a welding mode are embedded into the clamping grooves, and the clamps are used for clamping the end plates outside a joint core zone. The section shapes of the steel pipe concrete columns comprise a circular shape, a square shape and a rectangular shape. The section shapes of the steel beams comprise an H shape, an I shape and a box shape. The joint mode can be an angle joint, a side joint and a middle joint. The connecting joint does not use an outer annular plate, attractiveness is improved, using space is enlarged, meanwhile, load borne by the beams can be guaranteed and can be well transmitted to the steel pipe concrete columns, the whole steel pipe concrete columns are under stress, and the problem that during welding connecting, the steel pipe walls can deform by pulling or even be torn, and the steel pipe walls are damaged during bolting connecting is solved.

Description

technical field [0001] The invention belongs to the technical field of structural engineering in civil engineering, and in particular relates to a groove-assembled steel pipe concrete column-steel beam connection node. Background technique [0002] At present, the types of joints between CFST columns and steel beams are mainly concentrated in welding and bolting. In order to ensure the rigid connection requirements of beams and columns, an outer ring plate is also required. The study found that welding may cause the steel pipe wall to be deformed or even torn under tension. Bolting needs to destroy the steel pipe wall, and the installation of an outer ring plate affects the appearance and usable space. At the same time, these methods are complex in construction and high in cost. The present invention can solve the above problems. Contents of the invention [0003] The invention is a groove-assembled concrete-filled steel pipe column-steel beam connection node. The node ...

Problems solved by technology

[0004] The beneficial effect of the present invention is: the connection node does not need to use the outer ring plate, which increases the aesthetics and the use space, and at the same time ensures that the load borne by the beam can be well transmitted to the steel tube concrete column, so that the steel tube concrete column is stressed as a whole, Solve the problem that the steel pipe wall may be deformed or even torn during welding connection and the steel pipe wall may be damaged during bolted connection
