Rapidly mounted rectangular steel frame support of cast-in-place shear wall of fabricated building

Abstract

The invention discloses a rapidly mounted rectangular steel frame support of a cast-in-place shear wall of a fabricated building. The problems that walls, beams and plates of a fabricated building inthe prior art cannot be mounted simultaneously, the number of adopted steel pipes is large, and the labor and time are consumed are solved. A rectangular frame is composed of diagonal bracing multi-angle connecting parts at the center of the bottom face of the rectangular frame, rectangular frame right-angled multi-angle connecting parts, angle steel right-angled sides with telescopic joints in the middles and steel pipe diagonal bracings with telescopic joints in the middles, wherein the side lengths in the length, width and height directions of the rectangular steel frame can be adjusted, and the lengths of the telescopic joints are adjusted in the mode that an electric machine and a motor adjust the hydraulic oil amount of the telescopic joints. The rectangular steel frame is rapidly mounted, the working efficiency is improved, and the labor and time are saved. The rapidly mounted rectangular steel frame support has the advantages that mounting is flexible, the assembling speed of the rectangular steel frame is increased, the working efficiency is improved, overall stability is good, instability is not liable to occur, safety is good, steel materials are saved, and the labor, force and time are saved.

Description

Technical field: [0001] The invention relates to a prefabricated building cast-in-place shear wall formwork and a rectangular steel frame support for component installation; especially a multi-angle rectangular steel for quickly adjusting the size of the rectangular steel frame by using a mechanical or hydraulic method in scaffolding engineering in the construction field rack support. technical background: [0002] In the currently known cast-in-place shear wall structure of prefabricated construction projects, the support for cast-in-place concrete is composed of steel pipes, various buckles connecting the steel pipes, and scaffolding at the construction site, resulting in that the walls, beams, and slabs of the prefabricated building cannot be installed at the same time. Installation, the used steel pipe consumption is big, labor-intensive, time-consuming, and the phenomenon of instability occurs when the scaffolding occurs, causing safety accidents.
