Description

Stair mould for meeting common-mode production of stairs with different widths

Technical Field

The utility model belongs to the technical field of prefabricated staircase production, specifically a satisfy stair mould of different width stair common mode productions.

Background

The prefabricated staircase elements are relatively complex in shape compared to prefabricated composite slabs. According to the production conditions of other components, one surface of the component is generally selected as a bottom surface and is in contact with a mold table, other surfaces need to be combined and spliced by corresponding molds to form a closed space, and a reinforcement cage is placed in the closed space for pouring concrete. However, the positions of the prefabricated staircase, which can meet the production requirements, are the left side surface and the right side surface of the staircase, so that the existing common staircase mold adopts a vertical mold form.

However, the use of the vertical mold only solves the problem of stair production, and it is difficult to consider the problem of common mode. When the same project has the stair of different specifications, a set of mould of solitary just can't satisfy the production demand, can only purchase the mould again, what from this is that the mould cost increases, and reuse rate reduces a series of problems such as rate reduction.

Aiming at some simple conditions, the existing die can solve part of problems, for example, when the position of a sleeve is inconsistent with the position of a pin key hole, holes can be formed in the corresponding positions of the die for installation, and unnecessary holes are plugged. However, some dimensional problems, such as different step widths, cannot be met by this simple adjustment, and the mold can only be re-customized.
