Method for manufacturing rapidly-detachable rebuilt and reassembled composite building unit

Abstract

The invention discloses a method for manufacturing a rapidly-detachable rebuilt and reassembled composite building unit. The method includes the steps of firstly, respectively and independently prefabricating plates such as a top plate, wallboards and the like of the building unit, reserving post-cast strips and exposed reinforcing steel bars between the adjacent plates, and fixing the prefabricated wallboards on a bottom table and a formwork fixed at the outer side of the bottom table; fixing the top plate on a top plate support frame mounted on the bottom table, binding the reinforcing steelbars at the post-cast strips of the wallboards and the top plate, and mounting wallboard inner and outer molds and a top plate bottom mold; and then pouring concrete at the post-cast strips of the wallboards and the top plate to form the top plate and the wallboards which are integrally connected, and finally combining the wallboards with a bottom plate are to form the complete building unit. According to the method for manufacturing the rapidly-detachable rebuilt and reassembled composite building unit, a mold inner container does not need to be manufactured, and building units with the length and the width smaller than or equal to the length and the width of the bottom table can share one set of the molds, so that the use amount of the formworks can be greatly reduced, the mold manufacturing cost can be reduced, and mold mounting and mold dismounting are very rapid and easy.

Description

technical field [0001] The invention relates to a method for making a building structure, in particular to a method for making a prefabricated building unit in a rapidly detachable and rebuilt composite building. Background technique [0002] In order to avoid the problems of long construction period, difficulty in uniform quality and large interference to the surrounding area of ​​traditional cast-in-place concrete buildings, in the prior art, construction projects have gradually begun to use assembled composite buildings, that is, prefabricated reinforced concrete structures prefabricated in factories. Building units, such as prefabricated kitchens, prefabricated bathrooms, prefabricated bedrooms, etc., can be assembled together at the construction site, which can greatly reduce the amount of on-site construction work, shorten the construction time, reduce labor, and can greatly reduce the number of interference from surrounding residents. [0003] And when existing prefa...

AI Technical Summary

Problems solved by technology

[0004] The existing manufacturing method of this prefabricated building unit is because the contact surface between the inner and outer molds and the building unit is relatively large, so the bonding force between the mold and the building unit is also relatively large, and the prefabricated building unit and the film must be demoulded It is very difficult, and it often makes it difficult to lift prefabricated building units. This is a difficult problem in the production of prefabricated building units. At the same time, the amount and weight of the entire mold are very large, and the production cost of the mold is relatively high.
