Stair formwork structure and stair construction method adopting same

Abstract

The invention discloses a stair formwork structure and a stair construction method adopting the same. The formwork structure comprises stair side formworks, a stair bottom formwork and a supporting structure for the stair bottom formwork; a plurality of stair spacing formworks are further included, each stair spacing formwork is of a rectangular structure, and the stair spacing formworks are formed by cutting, bending and welding steel plates; one side of each stair spacing formwork is a plane and used for blocking concrete; the other side of each stair spacing formwork forms a groove-shaped structure with side walls, wherein the side walls comprise the upper and lower long side walls and the left and right short side walls; mounting holes are formed in each short side wall, and the stair spacing formworks are fixedly connected to the stair side formworks through screws penetrating through the mounting holes; each stair side formwork is a batten; and a prying opening is formed in the upper long side wall of each stair spacing formwork. The formwork has the advantages of being convenient to construct and remove, not prone to being damaged and long in service life.

Description

technical field [0001] The invention relates to the technical field of concrete staircase construction, in particular to a staircase formwork structure and a staircase construction method using the formwork structure. Background technique [0002] The construction process of the existing concrete stairs mainly includes steps such as supporting formwork, cast-in-place concrete, and concrete curing; when supporting the formwork, it is necessary to support the stair side formwork, the stair bottom formwork and the stair partition formwork; the existing stair formwork structure mainly There are steel structure formwork and wooden formwork; the use of steel structure formwork has the characteristics of stable structure, but due to its heavy weight, special equipment is required for erection, which makes erection inconvenient. [0003] The most commonly used wooden formwork then has the defects of easy damage and low service life. Contents of the invention [0004] Aiming at th...
