Quick butt joint fine-tuning device for upper layer and lower layer of steel-concrete combined pipes

Abstract

The invention discloses a quick butt joint fine-tuning device for an upper layer and a lower layer of steel-concrete combined pipes. The device comprises an upper rectangular flange and a lower rectangular flange which are horizontally arranged, a plurality of positioning plates are fixedly arranged on the inner wall of a rectangular hole in the upper rectangular flange, the lower side edge of each positioning plate extends into the rectangular hole of the lower rectangular flange, the lower side edge of each positioning plate is fixedly connected with a wedge-shaped clamping plate, the upperend of each wedge-shaped clamping plate is in contact with the lower side face of the lower rectangular flange, and the thickness of the lower side portion of each wedge-shaped clamping plate is smaller than that of the corresponding positioning plate. According to the invention, the butt joint speed between the upper and lower layers of the steel-concrete combined pipes can be greatly improved, atemporary fixing mode of buckles after butt joint is adopted, the upper layer steel-concrete combined pipe does not need to be hoisted all the time in the whole butt joint process of a crane, the operation efficiency of the crane is improved, the perpendicularity between the upper layer steel-concrete combined pipe and the lower layer steel-concrete combined pipe can be finely adjusted, the buttjoint quality and firmness are ensured, and the overall stress, energy conservation, earthquake resistance and other use requirements of modern fabricated buildings are completely met.

Description

technical field [0001] The invention belongs to the technical field of prefabricated building construction, and in particular relates to a fine-tuning device for quick docking of upper and lower layers of steel-concrete composite pipes. Background technique [0002] The single-section steel-concrete composite pipe used in the wall of the prefabricated building has a rectangular cylindrical structure as a whole. After being manufactured in the factory, it is transported to the construction site for assembly. The biggest problem with the popularization and application of the existing prefabricated buildings is that they cannot form a stable and unified system. , the key to this problem lies in the joint connection between the steel-concrete composite pipes, especially the butt joint quality between the steel-concrete composite pipes on the upper and lower floors. It is necessary to ensure that the verticality of the steel-concrete composite pipes on the upper and lower floors ...

[0002] The single-section steel-concrete composite pipe used in the wall of the prefabricated building has a rectangular cylindrical structure as a whole. After being manufactured in the factory, it is transported to the construction site for assembly. The biggest problem with the popularization and application of the existing prefabricated buildings is that they cannot form a stable and unified system. , the key to this problem lies in the joint connection between the steel-concrete composite pipes, especially the butt joint quality between the steel-concrete composite pipes on the upper and lower floors. Ensure that the verticality of the steel-concrete composite pipes on the upper and lower floors is consistent

The method used in the prior art for vertical connection of steel-concrete composite pipes is not only cumbersome to operate, but also difficult to adjust the verticality of the upper layer of steel-concrete composite pipes, which affects the installation quality
