Problems solved by technology
[0002] In multi-story residential buildings, when the main body is pouring concrete, it is extremely inconvenient for construction workers and inspection and acceptance personnel to go up and down the stairs. Not only is it unsafe, but it is also easy to damage the newly formed stair step formwork.
In addition, the support of traditional stair step formwork is extremely cumbersome, and the cross-sectional size cannot be reliably guaranteed. There are many unscientific and unreasonable places. The production process is complicated and the production cost is high.
[0003] Therefore, there are above-mentioned inconveniences and problems in the known traditional stair step formwork supporting method.

Embodiment 1
[0037] The construction method of the stereotyped steel stair steps of the present invention, its technological process: support bent frame erection→bottom formwork assembly→garbage cleaning in the mold→reinforcement binding, acceptance→stair steel steps hoisting in place→formwork correction and fixing→concrete pouring and maintenance→ Removal of stair steel steps→clean the surface of the stair steel steps and apply release agent. Its construction specifically includes the following steps:
[0038] a. Supporting and bending of prefabricated stairs, including the following steps:
[0039] (1) Make a number of rectangular steel plates as the stair tread plate 6 according to the width and height of the stair treads, and the thickness of the rectangular steel plates is 5mm.
[0040] (2) Make a number of right-angled triangle steel plates 9 according to the slope of the stairs and the size of the steps, the right-angled side of which is longer than the other right-angled side, and...

Abstract
The invention discloses a finalized steel stair step construction method which is characterized by comprising the following steps of a, prefabrication of a supporting bent of a stair; b, splicing of asupporting bent stair bottom die of the prefabricated stair; c, hoisting of the supporting bent of the prefabricated stair in place; d, regulation of the position of the supporting bent of the prefabricated stair; e, pouring and maintenance of concrete; and f, disassembly of the supporting bent of the stair. The finalized steel stair step construction method has the advantages that the supportingbent of the stair is simple in structure and convenient to manufacture and use, the forming quality of a stair step can be reliably ensured, passing of a work construction person as well as an inspection and acceptance person can be facilitated at the same time to ensure the safety of the persons, the construction time can be greatly reduced, operation is simple and convenient, the supporting bent of the stair can be repeatedly used and the engineering cost is reduced.
Description
technical field [0001] The invention relates to a construction method for stair steps, in particular to a construction method for stereotyped steel stair steps. Background technique [0002] In multi-story residential buildings, when the main body is pouring concrete, it is extremely inconvenient for construction workers and inspection and acceptance personnel to go up and down the stairs, which is not only unsafe, but also easily destroys the newly formed stair step formwork. In addition, the support of traditional stair step formwork is extremely cumbersome, and the cross-sectional size cannot be reliably guaranteed. There are many unscientific and unreasonable places, and the production process is complicated and the production cost is high. [0003] Therefore known traditional stair step formwork support method exists above-mentioned various inconveniences and problems. Contents of the invention [0004] The purpose of the present invention is to propose a constructio...
