Stair construction method through shaped supports

Abstract

The invention provides a stair construction method through shaped supports. The stair construction method through the shaped supports comprises the steps of (1) preparing the shaped stair supports, skirt board formworks, a bottom formwork and an opening side formwork; (2) carrying out erection of a supporting frame, assembly of the bottom formwork and laying of rebars at the position of a stair; (3) erecting the shaped stair supports, wherein a pair of shaped stair supports are symmetrically erected at the position of the stair through transverse steel pipes; (4) installing the skirt board formworks, wherein the skirt board formworks are transversely erected at skirt board formwork installing positions of the two shaped stair supports; (5) installing the opening side formwork; (6) carrying out pouring of concrete and maintenance; (7) carrying out formwork disassembly. Each shaped stair support in the step (1) comprises a long rod, a plurality of transverse short rods and a plurality of vertical short rods, wherein the tail ends of the transverse short rods are welded to the long rod according to the inclination of steps, the separation distance between every two adjacent transverse short rods is equal to the height of the corresponding designed step, each vertical short rod is vertically welded to the corresponding two adjacent transverse short rods, and each skirt board formwork installing position is formed by the corresponding vertical short rod and the corresponding two adjacent transverse short rods. The stair construction method through the shaped supports has the advantages that construction quality is high, the cost is low, and the construction period is short.

Description

technical field [0001] The invention relates to the technical field of building staircase construction. Background technique [0002] An existing construction method for building stairs, as disclosed in Chinese Patent Application No. 201110104747, includes the following steps: (1) making an "L"-shaped steel plate member according to the width and height of the stair steps, and welding two parallel The arranged channel steel assembles several "L"-shaped steel plate members into a stair-shaped step epidermis; (2) According to the size of the two sides of the stairs, the zigzag-shaped step end side form is made, and welded with the step epidermis to form the upper formwork (3) Build the supporting bent frame and the bottom form in sequence, and nail a small wooden strip on both sides of the edge of the bottom form, and install the upper formwork on the bottom formwork from the small wooden strips of the bottom form to form a closed staircase formwork; (4) Concrete pouring and ...

AI Technical Summary

Problems solved by technology

The disadvantage of this construction method is that the stepping epidermal formwork is used as the upper formwork of the staircase construction, which is very inconvenient during the construction of the stairs, and the concrete is not easy to fill the corners of the formwork, which affects the construction quality

This construction method has the characteristics of convenien...
