Stairway mold

Abstract

The invention provides a stairway mold which comprises a base and a step assembly arranged on the base. End molds are arranged at the ends of the step assembly. Side molds are arranged on the upper portion and / or the side faces of the step assembly. The step assembly comprises a plurality of step units. The step units are arranged on the base through adjusting mechanisms and can move and / or rotate on the base. According to the stairway mold of the structure, step panels can rotate by a certain angle relative to the base under the action of the adjusting mechanisms, so that the included angle between the step panels and the base is changed. Meanwhile, the step panels can move by a certain distance relative to the base under the action of the adjusting mechanisms, that is, the distance between every two adjacent step units can be changed, and therefore the aim of producing stairways of different specifications can be achieved by moving and / or rotating the step panels. Therefore, one mold has multiple purposes, the use efficiency of the stairway mold is improved, and the production and action cost is lowered.

Description

technical field [0001] The invention relates to the field of building molds, in particular to a staircase mold. Background technique [0002] At present, the stair molds used to produce stairs mainly include two types, namely, vertical stair molds and flat stair moulds. Both stair molds are designed and produced according to the size of the stairs, and their length, width and height are fixed. That is, each staircase mold can only produce one kind of staircase. Once the size of the staircase changes, a new mold needs to be redesigned. Therefore, the staircase mold has poor versatility and high production and use costs. [0003] In the Chinese patent with the application number 201410328675.9, an adjustable universal stair formwork is disclosed, including a step surface formwork, a step riser formwork and a side formwork, a length adjustment mechanism is provided on the step surface formwork, and a The height adjustment mechanism is equipped with a stair angle adjustment str...

Problems solved by technology

[0004] Although the general staircase formwork with the above structure can adjust the size of the staircase, the structure is relatively complicated, the adjustment effect is poor, and the production cost and use cost are high.
