Modular size-adjustable prefabricated stair mold

Abstract

The invention discloses a modular size-adjustable prefabricated stair mold which comprises a base platform (1). The top surface of the base platform is fixedly connected with a stair back main mold plate (2), the stair back main mold plate is connected with an upper end mold plate (3), and the upper end mold plate is connected with an upper platform mold plate (4). The stair back main mold plate is connected with a stair back adjusting mold plate (5), the stair back adjusting mold plate is connected with a lower end mold plate (6), and the lower end mold plate is connected with a lower platform mold plate (7). The upper platform mold plate and the lower platform mold plate are connected through a group of stair step mold plates (8) to form an end-to-end stair-shaped closed pouring cavity (9). The top of the upper platform mold plate is connected with the top of the stair back main mold plate through a long screw rod (10). The top of the lower platform mold plate is connected with the top of the stair back adjusting mold plate through a long screw rod. Most of the mold plates can be repeatedly used. When the size of prefabricated stairs is changed, assembly of the whole mold can be achieved only by customizing a very few mold plates. The use cost of the mold is reduced.

Description

technical field [0001] The invention relates to a modular size-adjustable prefabricated staircase mold, which belongs to the technical field of fabrication of assembled building molds. Background technique [0002] There are two types of molds for prefabricated stairs in the prior art: horizontal staircase molds and vertical staircase molds. No matter which type of mold it is, in general production, it is basically designed and processed separately according to the specifications or types of stairs in the project. Mold, and the mold can only produce this type of size. After the completion of the production of the project stairs, the stair molds are difficult to use in the next project due to the fixed specifications and sizes. Only a few can be modified and continued to be used, resulting in low mold turnover and reuse rates and high amortization costs. , and waste of resources. Therefore there are still deficiencies in the prior art and need to be further improved. Cont...
