Prefabricated stair mold and processing technology of prefabricated stair thereof

Abstract

The invention relates to a prefabricated stair mold and a processing technology of a prefabricated stair thereof. The mold comprises a bottom mold body, a back mold body, a step mold body, end mold bodies and a grooving piece, wherein the back mold body and the step mold body are vertically arranged at the top of the bottom mold body; the back mold body and the step mold body are oppositely arranged; the end mold bodies are arranged at the two ends of the back mold body; a pouring cavity is formed among the bottom mold body, the back mold body, the step mold body and the end mold bodies; a reserved groove is formed in the top of the bottom mold body in the length direction of the back mold body; the grooving piece is matched with the reserved groove and arranged between the back mold body and the step mold body in the length direction of the back mold body; and the two ends of the grooving piece are connected with the end mold bodies on the two sides respectively. According to the processing technology, the mold is cleaned firstly, so that the quality of a prefabricated stair finished product after pouring is improved; and forming of the prefabricated stair is completed through one set of mold, so that mold materials are saved, and the production cost is reduced. The prefabricated stair mold and the processing technology of the prefabricated stair thereof provided by the invention has the beneficial effects that the prefabricated stair capable of being spliced can be conveniently produced, and the produced prefabricated stair is convenient to transport and install.

Description

technical field [0001] The present application relates to the technical field of prefabricated stairs, in particular to a mold for prefabricated stairs and a processing technology for prefabricated stairs. Background technique [0002] Stairs are components used as vertical traffic between floors in buildings, and are used for traffic connections between floors and when the height difference is large. In the process of staircase construction, prefabricated staircases have been proposed in recent years. Prefabricated stairs refers to the transfer of a large number of on-site operations in the traditional construction method to the factory. The stairs are made by mold processing in the factory, and the prefabricated stairs are transported to the construction site, assembled and installed on the building through reliable connection methods. inside the thing. [0003] The Chinese invention patent with the application number CN201811352718.1 discloses a prefabricated staircase ...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: when the prefabricated stairs are produced by using the above-mentioned molds, the entire prefabricated stairs are integrally formed, resulting in a large dead weight of the prefabricated stairs, which directly affects the transportation of the prefabricated stairs, and at the same time When installing prefabricated stairs, it also increases the difficulty of lifting
