Split type prefabricated stair integrated forming die and stair production method

Abstract

The invention relates to a prefabricated building, in particular to a split type prefabricated stair integrated forming die and a stair production method. A partition plate is arranged in the middle of a step forming face of the die, a first side flange is arranged on one side of the step forming face, a second side flange is arranged on the other side of the step forming face, a female tongue-and-groove forming boss is arranged on the upper portion of the inner side of the first side flange, a male tongue-and-groove forming concave portion is arranged on the lower portion of the inner side ofthe second side flange, a left sub-stair and a right sub-stair of a split type stair can be formed in the same die in a one-time pouring and tamping manner, and therefore the die cost of the prefabricated stair is reduced, the production efficiency is improved, and step dislocation generated when the left sub-stair and the right sub-stair are spliced is avoided.

Description

Technical field[0001]The invention relates to a prefabricated staircase, in particular to a split prefabricated staircase integral molding die and a staircase production method.Background technique[0002]In prefabricated buildings, prefabricated stairs are often overweight and cannot be lifted.figure 1 As shown, the prefabricated stairs are divided into the left sub-ladder 1'and the right sub-ladder 2'from the middle to achieve the weight reduction effect during hoisting. At the same time, the connecting parts of the left sub-ladder 1'and the right sub-ladder 2'are respectively provided with connecting devices. To strengthen the connection, and ensure that the left sub-ladder 1'and the right sub-ladder 2'are installed flush.[0003]Although the above method of splitting the prefabricated stairs into prefabrication solves the problem of overweight during hoisting, after the prefabricated stairs are split, two sets of stair molds are usually required to make the left sub-ladder 1'and the...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a method that can use one set of molds for the production of split prefabricated stairs, and effectively improve the mold cost and labor efficiency, in view of the shortage that the existing split prefabricated stairs need two sets of molds for production.
