Problems solved by technology

[0003] The advantages of the CFST slab-column structure are outstanding, but punching damage is prone to occur at the joints in the slab-column, and triggers a chain effect, causing damage to adjacent nodes, resulting in the collapse of the overall structure
In order to prevent this kind of failure, the punching shear bearing capacity of mid-joints is usually increased by configuring shear reinforcement and setting anchor bolts. Punching resistance needs at

Abstract

The invention discloses a slab-column middle joint connection structure, a steel tube concrete slab-column structure comprising the slab-column middle joint connection structure, and a construction method for the steel tube concrete slab-column structure, and relates to the field of steel tube concrete stiffening hybrid structures. The slab-column middle joint connection structure comprises a square steel pallet, four positioning steel plate components and a positioning slider component. Compared with traditional methods of anchor bolts and shear reinforcements and the like, the square steel pallet, the positioning steel plate components and the positioning slider component can be combined to achieve continuous shear resistance. Punching resistance performance of a slab-column middle jointis greatly improved and needs of the punching resistance of the slab-column middle joint are met. At the same time, the positioning slider component can be used to realize an accurate positioning ofan upper bidirectional steel net and a lower bidirectional steel net and construction efficiency is accelerated.

Description

technical field [0001] The invention relates to the field of steel tube concrete stiffening hybrid structures, in particular to a joint connection structure in a slab-column, a steel tube concrete slab-column structure and a construction method. Background technique [0002] The concrete-filled steel tube slab-column (concrete-filled steel tube laminated column-reinforced concrete slab) structure is a further development of the traditional frame structure. Because there are no beams between the columns, the building space can be fully utilized, the overall building height is reduced, and the room partition layout is flexible. At the same time, the concrete-filled steel tube composite column has a high bearing capacity, which can effectively reduce the section size of the column, further increase the usable space, have good economic benefits, and meet people's housing needs to a great extent. [0003] The advantages of the CFST slab-column structure are outstanding, but punch...
