Stair step directional steel formwork and construction method

Abstract

The invention discloses a stair step directional steel formwork. The stair step directional steel form comprises a supporting frame, a supporting form and a step ladder steel form, wherein the supporting frame is vertically and fixedly mounted between an upper floor and an lower floor and is used for supporting and fixing the supporting form, the supporting form is obliquely mounted between the upper floor and the lower floor, the step ladder steel form is fixed along the surface of the supporting form, two or more fixing channel steel strips are mounted above the step ladder steel form in parallel, and the fixing channel steel strips, the step ladder steel form and the supporting form are fixedly connected through pull rod assemblies. A construction method is further disclosed. Concrete slurry is continuously poured from a grouting port at the top end of the step ladder steel form until the step ladder steel form is full, and after the concrete slurry reaches the specified strength, the steel formwork is removed in sequence. According to the stair step directional steel formwork, after the concrete is poured and shaped, the steel formwork can be easily disassembled, all parts of the supporting form assembly can be reused, circulation is facilitated, and material consumption and cost of construction are reduced.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a stair step directional steel formwork and a construction method. Background technique [0002] Stairs are an important structure in housing construction. At present, with the development of housing construction science, the requirements for architectural patterns such as housing and infrastructure are also constantly improving, and architectural design styles are also constantly developing. The design patterns of high-rise and super high-rise buildings are increasing. Another On the one hand, the construction industry itself has certain requirements on the safety, quality, progress and cost of buildings. As an important structure in building construction, stairs are an important passage between upper and lower floors. Due to their special shape, special molds are required for pouring construction. At present, in the process of stair construction, the ...

AI Technical Summary

Problems solved by technology

At present, in the process of stair construction, the stair steel formwork is first made according to the designed shape and size, and then the assembly plate is assembled into a trapezoidal support steel formwork, and then concrete is poured on the support steel formwork. During the pouring process, grout leakage and swelling often occur mold quality defects

The supporting steel formwork is fixed and assembled by connecting parts such as spindles. Since the formwork is not easy to disassemble and turn around after concrete pouring, and some fixed connecting parts are located inside the formwork, it is difficult to dismantle the formwork. The concrete surface of the stairs can be obviously observed to be honeycomb pockmarked, and the flatness of the step surface is poor, which seriously affects the quality of concrete pouring and molding
