An assembled aluminum alloy staircase formwork

Abstract

The invention discloses an assembled aluminum alloy stair formwork, which relates to the technical field of stair formwork. The key point of the technical solution is to include slanting braces and multiple sets of stair modules fixed on the top of the slant braces. Each set of stair modules includes oppositely arranged The two support plates fixed on the top of the diagonal braces, the two horizontal stair plates respectively fixed on the top of the two support plates, the two fixed plates respectively fixed on the top of the transverse stair plates, and the two fixed plates on the top of the transverse stair plates are rotatably installed away from the diagonal braces. The vertical stair board on one side of the board; two sets of rotating devices for driving the rotation of the vertical stair board are arranged between the horizontal stair board and the vertical stair board. The invention solves the problem that the stair formwork is inconvenient to carry, and achieves the effect of facilitating the construction and transportation of the stair formwork.

Description

technical field [0001] The invention relates to the technical field of stair formwork, more specifically, it relates to an assembled aluminum alloy stair formwork. Background technique [0002] At present, the stairs in the building are generally made of concrete pouring or masonry. The masonry construction requires more manpower than the concrete pouring method, and the operation time is long, so the concrete pouring stairs are widely used in the prior art. [0003] For the prior art, please refer to the Chinese utility model patent whose authorized announcement number is CN202882417U, which discloses a stair formwork structure, including stair side formwork and step formwork. The top of the stair side formwork is provided with evenly arranged limiting grooves, each The limit groove includes a bottom wall and a front wall and a rear wall fixed on the top of the bottom wall; the stair formwork structure also includes a positioning block and an ax tip arranged in the limit gr...

Problems solved by technology

[0004] However, the integrated structure of the above-mentioned stair formwork makes the overall structure of the stair formwork larger, which affects the handling of the stair formwork, which in turn causes inconvenience during construction between floors.
