Assembly method of steel-concrete composite pipe thin-walled steel plate turning hole tapping screw connection

Abstract

An assembling method for steel-concrete composite pipe thin-wall steel plate hole flanging, taping and screw connection comprises the following steps that (1) a plurality of through holes are formed in two steel plates through a hole flanging technology, conical turnup structures are formed, the long sides of angle steel flanges are provided with two rows of drilled holes, and one sides of the drilled holes are provided with conical chamfer structures; (2) two pieces of U-steel and two steel plates are made into a rectangular steel pipe; (3) Rachel screws are rotationally inserted into the through holes; (4) the angle steel flanges and the steel plates are fixedly connected into a whole; and (5) the lower ends of the two pieces of U-steel are provided with two rectangular plates. Accordingto the assembling method, design is reasonable, the structure is compact, the bolt connection mode is adopted, the thickness of the steel plates capable of being 1-3 thick can be sufficiently decreased, and accordingly, the weight and cost of a steel-concrete composite pipe are reduced.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to an assembly method for connecting steel-concrete composite pipes with thin-walled steel plates with turning holes and tapping screws. Background technique [0002] The components of the prefabricated building are prefabricated in the factory or on the construction site, and then assembled on site. The steel-concrete composite pipe is a wall component. Due to the increasing number of high-rise buildings, the quality of the butt joint between the upper and lower floors of the steel-concrete composite pipe It is related to the construction quality of the entire building. At present, the upper and lower sides of the two steel plates in the steel-concrete composite pipe and the upper and lower ends of the two channel steels are welded with rectangular flanges. The welding length between the rectangular flange and the two steel plates is relatively long. There...

Problems solved by technology

[0002] The components of the prefabricated building are prefabricated in the factory or on the construction site, and then assembled on site. The steel-concrete composite pipe is a wall component. Due to the increasing number of high-rise buildings, the quality of the butt joint between the upper and lower floors of the steel-concrete composite pipe It is related to the construction quality of the entire building. At present, the upper and lower sides of the two steel plates in the steel-concrete composite pipe and the upper and lower ends of the two channel steels are welded with rectangular flanges. The welding length between the rectangular flange and the two steel plates is relatively long. , in order to avoid the reliability of the welding and the deformation of the steel plate, the thickness of the steel plate must be relatively large, which causes the weight and cost of the steel-concrete composite pipe to increase a lot
