Problems solved by technology

At present, the stair molds used in the factory are mainly divided into two categories. One is the conventional stair mold. This kind of stair mold can only produce a single specification of stairs. Different projects need to redesign the mold and process it. The waste of materials is serious, and it takes time, manpower and financial resources. Larger; the second type is the horizontal adjustable staircase mould, which can adjust the width of the stairs or the height of the steps of the stairs, but this kind of mold is generally 4 times the weight of the conventional mold due to the complicated adjustment mechanism, and the production cost is high

Abstract

The prefabricated stair mold comprises a base and side molds located on the two sides of the base respectively, a plurality of stepping pieces are arranged between the side molds on the two sides, andthe stepping pieces are detachably connected in sequence and can move up and down to adjust the relative height between the adjacent stepping pieces. Each stepping piece comprises a horizontal part,a first vertical part and a second vertical part, the first vertical part and the second vertical part are perpendicularly connected with the two sides of the horizontal part respectively, at least two arc-shaped supporting frames are arranged between the first vertical part and the horizontal part, and each supporting frame abuts against the base. According to the prefabricated stair mold, the stepping pieces rotate on the base, so that the relative height between two adjacent stepping pieces is adjusted, and the height of the prefabricated stair is adjusted; and the stepping pieces are detachably connected, so that the length of the whole prefabricated stair can be adjusted according to the number of the stepping pieces required to be mounted on the prefabricated stair.

Description

technical field [0001] The invention belongs to molds for prefabricated concrete components, in particular to a mold for prefabricated stairs. Background technique [0002] With the development of the construction industry, prefabricated buildings have been widely recognized by people. Prefabricated building refers to the transfer of a large number of on-site operations in the traditional construction method to the factory, where the building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, and transported to the construction site. Reliable connections are assembled and installed on site. [0003] Stairs are important components in construction, and prefabricated staircase molds are required for the production of prefabricated stairs. At present, the stair molds used in the factory are mainly divided into two categories. One is the conventional stair mold. This kind of stair mold can only ...
