Stair manufacturing process of fabricated building

Abstract

The invention discloses a stair manufacturing process of a fabricated building, and relates to the technical field of buildings. The manufacturing device comprises a base, two supporting frames are fixedly mounted at the top of the base, mounting frames are rotatably mounted at the tops of the two supporting frames, a driving motor is fixedly mounted at the top of the base, and an output shaft of the driving motor is in transmission connection with one mounting frame through a transmission belt. The pouring mold cavity is constructed through the modules, disassembly and assembly are easy, the prefabricating speed of stair accessories in an assembly type building is increased, secondly, after concrete is poured into the pouring mold cavity, the internal concrete is evenly distributed in a multiple-rotation mode, during extrusion, the concrete can be pushed and extruded by the preset storage tank mechanism on one side, and the concrete on the other side can be slightly loosened, so that the construction efficiency is improved. And concrete in the pouring mold cavity repeatedly wriggles, bubbles generated by internal pouring are discharged, the phenomena of hollowing and bubbles in the prefabricated stair can be effectively reduced, and the quality of stair prefabrication is improved.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to a stair manufacturing process for a prefabricated building. Background technique [0002] Prefabricated building refers to the transfer of a large number of on-site operations in the traditional construction method to the factory, where the building components and accessories (such as floors, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, and transported to the construction site. Reliable connections are assembled and installed on site. Prefabricated buildings mainly include prefabricated concrete structures, steel structures, modern wooden structures, etc., because of the use of standardized design, factory production, assembly construction, information management, and intelligent applications, they are representatives of modern industrial production methods.

AI Technical Summary

Problems solved by technology

[0003] Stairs are an indispensable accessory in multi-storey prefabricated buildings. As a component for vertical traffic between floors in a building, they are mainly used for traffic connections between floors and when the height difference is large. Stair accessories in prefabricated buildings, Most of them are processed in the factory, and the concrete is poured in the frame mode. The traditional processing method is cumbersome to install and remove the formwork, and there are air bubbles in the stairs during the pouring process, which affects the appearance and quality of the stairs.
