Description

Technical Field

[0001] The present invention belongs to the technical field of construction, and particularly relates to a connection structure between a building steel frame and a composite slab that is convenient for assembly. Background Art

[0002] A concrete composite slab is an assembled monolithic structure composed of a precast prestressed concrete bottom slab (or called precast bottom slab) and a cast-in-place concrete layer (or called cast-in-place slab), which has good integrity and seismic resistance. The concrete composite slab saves the formwork in construction, speeds up the construction progress, and thus reduces the project cost. At present, the technological process of fabricating a concrete composite slab at the construction site is as follows: laying the precast bottom slab at the construction site, casting concrete on the precast bottom slab, and the cast-in-place concrete forms the cast-in-place slab after solidification, thus forming the precast concrete composite slab.

[0003] Due to the large self-weight of the integral precast concrete composite slab, the precast composite floor slab is prone to breakage during transportation and hoisting, and temporary supports need to be set during the construction and installation process. The existing temporary supports are fixed to the precast bottom slab by welding or bolt fastening. After the precast concrete composite slab is transported to the designated position, the temporary supports are not convenient for disassembly and reuse, resulting in an increase in construction measure costs and low construction efficiency.

[0004] At the same time, the existing temporary supports are prone to shaking during hoisting, posing a great safety hazard, and the shaking composite slab is more likely to rub against its top, damaging the temporary supports and the composite slab, seriously affecting the construction efficiency. Summary of the Invention

[0005] The purpose of the present invention is to: in order to solve the problems that the existing temporary supports are fixed to the precast bottom slab by welding or bolt fastening, and after the precast concrete composite slab is transported to the designated position, the temporary supports are not convenient for disassembly and reuse, resulting in an increase in construction measure costs and low construction efficiency, and the existing temporary supports are prone to shaking during hoisting, posing a great safety hazard, and the shaking composite slab is more likely to rub against its top, damaging the temporary supports and the composite slab, seriously affecting the construction efficiency, a connection structure between a building steel frame and a composite slab that is convenient for assembly is proposed.

[0006] In order to achieve the above purpose, the present invention adopts the following technical scheme: a connection structure between a building steel frame and a composite slab that is convenient for assembly, including a precast bottom slab, a plurality of vertical reinforcement plates are arranged on the precast bottom slab, a plurality of through holes are arranged on the vertical reinforcement plates, a plurality of steel bars pass through the through holes, concrete is poured on the precast bottom slab and submerges the vertical reinforcement plates, a hanging square pipe is arranged at the bottom of the precast bottom slab, and an anti-shaking hanging member is arranged on the hanging square pipe.

[0007] As a further description of the above technical solution:

[0008] A plurality of the vertical reinforcement plates are arranged equidistantly on the precast bottom plate.

[0009] As a further description of the above technical solution:

[0010] A plurality of the through holes are arranged in a matrix on the vertical reinforcement plate.

[0011] As a further description of the above technical solution:

[0013] As a further description of the above technical solution:

[0014] The installation groove is in a shape of a Chinese character 'tu'.

[0015] As a further description of the above technical solution:

[0016] A limiting groove is provided on the hanging square pipe, a connecting hole is provided upward in the limiting groove, the bottom of the anti - swaying hanging member abuts in the limiting groove, and the top extends outside the hanging square pipe through the connecting hole.

[0017] As a further description of the above technical solution:

[0018] The anti - swaying hanging member includes a gear seat, a connecting groove and an adjusting rod. The connecting groove is connected to the gear seat, and the adjusting rod is screwed in the connecting groove in a vertically adjustable manner.
