Prefabricated assembly-type stair module-type combined die and installing method thereof

Abstract

The invention discloses a prefabricated assembly-type stair module-type combined die and an installing method thereof. The prefabricated assembly-type stair module-type combined die comprises a base,a step standard module, a lower platform upper surface module, a lower platform lower surface rotating module, an upper platform upper surface module, an upper platform lower surface rotating module,a lower surface general module and a lower surface adjusting module. Through a size positioning hole installed in each splicing module, different size specifications of prefabricated stair dies are formed, and sliding holes at two ends are used for fixing. Compared with former dies for realizing size adjustment in other modes, the die is higher in positioning precision, smaller in accumulated error, and capable of improving installing efficiency of the prefabricated stair die. The lower platform lower surface rotating module and the upper platform lower surface rotating module can be adjustedin angle through a rotating shaft, and cooperated with the stair for adjusting the angle through arranging different lengths of arc sliding chutes on the general module, so the whole prefabricated stair die is conveniently installed. A minimum dosage of a complete die material is realized, and die cost is reduced.

Description

Technical field [0001] The invention relates to a staircase mould, in particular to a prefabricated assembly type staircase modular combined mould and an installation method thereof, belonging to the technical field of staircase moulds. Background technique [0002] As my country vigorously promotes the process of building industrialization, a large number of prefabricated concrete structures have been built. The prefabricated concrete structures are produced in the processing plant and the prefabricated components are then transported to the construction site for assembly. Prefabricated stairs are the most common split component in prefabricated concrete structures. Compared with traditional cast-in-situ stair structures, prefabricated stairs can achieve the advantages of short construction period, high efficiency and easy operation. However, because the current prefabricated concrete structure design has not reached the forward design, the traditional design method is mainly us...

AI Technical Summary

Problems solved by technology

However, since the current prefabricated concrete structure design has not yet reached the forward design, the traditional design method is mainly used to design the concrete structure, and then split, which results in too many specifications and sizes of prefabricated stairs. Just need a staircase mold

Therefore, manufacturers of prefabricated components need to prepare a large number of moulds, and some molds of certain specifications may only be used once. The increase in mold costs will virtually increase the operating costs of the manufacturer, which is not conducive to the promotion of prefabricated structures.
