Integral stair formwork structure and construction method thereof

Abstract

The invention relates to an integral stair formwork structure and a construction method thereof. The integral stair formwork structure comprises supports, two supporting beams, formwork supporting members, stair bottom formworks, stair side formworks, step formworks and hanging members, the supporting beams are arranged parallelly, inclination of each supporting beam is identical with gradient of stairs, two ends of the supporting beams are fixed on two layers of slowgoing platforms through the supports respectively, the formwork supporting members are arranged at positions, corresponding to the step, along the longitudinal direction of the supporting beams, the stair bottom formworks and the stair side formworks are hung on the formwork supporting members after being paired, each hanging member is composed of a bottom formwork supporting steel pipe and a hook, each bottom formwork supporting steel pipe is transversely arranged below the corresponding stair bottom formwork, two ends of each bottom formwork supporting steel pipe are connected with the corresponding formwork supporting member through the corresponding hook, and each step formwork is arranged between two formwork supporting members on a same cross section. The integral stair formwork structure is convenient to mount and adjust, few in stair step error and conducive to guaranteeing construction quality; a stair formwork is of an integral structure, and a stair bottom support is omitted, so that circulating materials can be saved, and construction efficiency can be improved substantially.

Description

technical field [0001] The invention relates to a stair formwork structure, in particular to an integral stair formwork structure and a construction method thereof. Background technique [0002] Double run stairs and scissor stairs are the most common types of stairs in high-rise residential stairs, especially scissor stairs. The most notable feature of this type of project is that after entering the standard floor, the elevation, size, step elevation, size, and number of steps of the stairs, etc. totally agree. For residential buildings with few units, due to the small number of stairs, the use of wooden formwork during the construction of the stairs requires little work and does not affect the construction progress. However, for the construction of multiple residential buildings with multiple identical units in each building, the use of stair wood formwork to assemble scattered formwork will result in too much time-consuming assembly and reinforcement on site, which will ...

Problems solved by technology

However, for the construction of multiple residential buildings with multiple identical units in each building, the use of stair wood formwork to assemble scattered formwork will lead to too much time-consuming assembly and reinforcement on site, which will affect the construction progress.

Moreover, when using wooden formwork for construction, due to the on-site assembly, the working surface is small, which is inconvenient for construction, and the assembled stairs have a large step error, which affects the overall quality of the stairs.

In addition, the traditional stair formwork needs to support the inclined run first, then lay steel bars on the inclined run, then support the step formwork, and finally reinforce it. The construction process is relatively complicated.
