Upper-air formwork support and outer scaffold shared cantilever structure

Abstract

The invention discloses an upper-air formwork support and outer scaffold shared cantilever structure, and belongs to the technical field of buildings. The upper-air formwork support and outer scaffoldshared cantilever structure comprises cantilever steel beams, a horizontal rectangular steel plate, a U-shaped pull ring and the like. The cantilever steel beams comprise a first cantilever steel beam and a second cantilever steel beam, the first cantilever steel beam is in lap joint to a floor, the lap-joint end of the first cantilever steel beam and the floor is connected through the U-shaped pull ring, the horizontal rectangular steel plate is mounted on the bottoms of the first cantilever steel beam and the second cantilever steel beam, the second cantilever steel beam is connected with the side of the floor, and rectangular hollow braces and triangular steel plate are mounted between the lower portion of the horizontal rectangular steel plate at the bottoms and the side wall of the floor. Through the structure system, the horizontal rectangular steel plate is mounted, the first cantilever steel beam and the second cantilever steel beam are better stressed, it is ensured that a formwork support and an outer scaffold are erected at the same time, bearing capacity is high, all cantilever steel beams adopt brace types, a traditional single steel wire rope is not adopted for inclined bracing, the stability of the cantilever steel beams is improved, and stability and safety of a cantilever scaffold can be improved.

Description

technical field [0001] The invention belongs to the technical field of construction, in particular to a cantilever structure shared by high-altitude formwork supports and external scaffolding. Background technique [0002] Scaffolding mainly refers to various supports set up for the convenience of workers and to solve vertical and horizontal transportation during on-site construction. Among them, the cantilever scaffold can be divided into cantilever type, cable-stayed type and under-bracing type. The cantilever type is to use section steel as a cantilever beam, and the cable-stayed type is to use a cantilevered steel beam protruding from the building structure to be cable-stayed by a wire rope or a rod, and the other end of the cable-stayed rod is fixed to the beam or column on the upper floor. The inner and lower bracing type is to add oblique support to the lower part of the cantilevered steel beam. [0003] In the prior art, in many projects, the cantilever section of ...

Problems solved by technology

[0004] In order to solve the above-mentioned technical problems, the present invention provides a cantilever structure shared by the high-altitude formwork support and the external scaffolding, mainly for the purpose of developing a structure with good bearing capacity, clear force performance, convenient formwork support, and time-saving for later sealing the wall. The labor-saving structure can effectively solve the problems of unclear force on the cantilevered steel beam, low bearing capacity, reduction of wall damage by perforation, and consumption of manpower, material and financial resources.
