High-strength reinforced concrete prefabricated stair pouring forming method

Abstract

The invention relates to a high-strength reinforced concrete prefabricated stair pouring forming method. The method uses a high-strength reinforced concrete prefabricated stair pouring forming machine, the machine comprises a mounting base, first supporting columns, second supporting columns, an inclined plate and a forming device, first supporting columns are symmetrically arranged on the front side and the rear side of the right side of the upper end face of the mounting base, the second supporting columns are arranged on the left sides of the first supporting columns, the upper ends of the first supporting columns and the upper ends of the second supporting columns are connected with the inclined plate, and a forming device is arranged on the inclined plate. The method can solve the problems that a traditional concrete stair installation construction method is complex in operation, the installation construction time of a cement stair is greatly prolonged, the preparation efficiency of the cement stair is reduced, wood boards are wasted at the same time, a traditional jolt ramming method is difficult to jolt the concrete in a concrete prefabricated part, the working intensity of cement prepared from the concrete prefabricated part is low, and potential safety hazards are possibly caused.

Description

technical field [0001] The invention relates to the technical field of concrete preparation, in particular to a pouring molding method for high-strength reinforced concrete prefabricated stairs. Background technique [0002] Reinforced concrete refers to a composite material formed by adding steel mesh, steel plates or fibers to concrete to improve the mechanical properties of concrete, among which reinforced concrete is the most common form. Reinforced concrete prefabricated parts refer to concrete products processed and produced in factories through standardized and mechanized methods. The corresponding traditional cast-in-place concrete requires on-site mold making, on-site pouring and on-site maintenance. The use of concrete prefabricated parts can reduce on-site production of concrete. Increase the amount of structure and increase the rate of prefabrication. [0003] At present, when concrete stairs are installed and constructed, there are usually the following defects...

AI Technical Summary

Problems solved by technology

[0005] The invention can solve the problem of installation and construction of traditional concrete stairs. Usually, concrete prefabricated parts are not used for preparation, but the wooden boards are directly installed into molds, concrete is injected, and then the wooden boards are disassembled. The operation is cumbersome and greatly prolongs the installation and construction time of cement stairs. , which reduces the preparation efficiency of cement stairs, and also causes waste of wood boards, and after the installation and construction of traditional concrete stairs is completed, it is difficult to shake the concrete in the concrete prefabricated parts by the traditional vibration method, resulting in the preparation of the concrete prefabricated parts The working strength of cement is low, and the density of concrete in concrete stairs is often insufficient. There will be large and small gaps in the concrete, which will affect the quality of concrete stairs and may bring safety hazards and other problems.
