Construction technology for line slot reserving of fabricated building prefabricated composite slab

Abstract

The invention relates to the technical field of building construction, in particular to a construction technology for line slot reserving of a fabricated building prefabricated composite slab. The construction technology comprises the steps that a model and a civil model are comprehensively mounted by adopting a BIM technique, a precise electrical pipeline laying diagram is provided, then at the pouring state of a prefabricated layer of a reserved slab, an electrical junction box is buried, and electrical pipeline reserved slots are reserved, then a cast-in-place layer is poured, and thus a final finished product is obtained. According to the construction technology, it is ensured that enough line pipes are arranged under the premise that the composite slab is not affected by pipeline laying as far as possible.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction process for reserved wire grooves of prefabricated laminated panels in prefabricated buildings. Background technique [0002] A building assembled on site by prefabricated components is called a prefabricated building. According to the form and construction method of prefabricated components, it is divided into five types: block building, plate building, box building, skeleton plate building and rising plate building. [0003] In recent years, with the rapid development of prefabricated buildings in China, new prefabricated buildings have sprung up all over the country. However, due to the thin thickness of cast-in-place concrete on the surface of prefabricated concrete components, and the distribution of hydropower pipelines in residential projects, it is necessary not only to ensure the normal pre-buried of hydropower pipelines, but also to ensure ...

AI Technical Summary

Problems solved by technology

[0004] Prefabricated laminated slabs are divided into cast-in-place floors and prefabricated floors. In traditional cast-in-place buildings, the thickness of residential floors is generally 100-120mm. However, according to prefabricated buildings, there are specifications and atlases. The thickness is generally 60mm, and the thickness of cast-in-place slabs is generally 70mm. The layout of water and electricity pipelines above the laminated slab often has a handover area. The diameter of commonly used PVC pipes for water and electricity pipelines is about 20mm-30mm. If two PVC pipes Laying steel bars above the water pipes after crossing will lead to the thickness of the protective layer of the surface steel bars not meeting the requirements, and there will be construction quality problems such as exposed bars. Therefore, a construction method suitable for prefabricated laminated slab reserved wire slots is needed
