Method for splicing and connecting precast reinforced concrete floor slabs within span

Abstract

The invention relates to a method for splicing and connecting precast reinforced concrete floor slabs within a span, and belongs to the field of construction method of precast reinforced concrete overlapped floor slabs for buildings. The method comprises the following steps of: firstly, installing reserved plate bottom steel bars and plate bottom steel bars of the floor slabs in a floor slab component, of which the steel bars at the ends are reserved outside the floor slab component, and each steel bar of the reserved plate bottom steel bars of the floor slab is provided with a vertical hook; secondly, fastening and connecting the reserved plate bottom steel bars of the floor slabs, the vertical hooks and late cast concrete with plate bottom steel bars through metal binding wires, and then screwing a spiral steel wire cover at the fastening joint of the metal binding wires; thirdly, fixing the spiral steel wire cover at the fastening joint of the metal binding wires by overlapping the late cast concrete; and fourthly, repeating the above steps through longitudinal plate bottom steel bars of the floor slabs so as to realize longitudinal connection of slab components. According to the method, the overlapped precast reinforced concrete floor slabs are simple to manufacture and simple in construction technology, the quality is easily ensured, the production and transportation efficiency is improved, the building construction quality can be ensured, and the construction cost is reduced.

Description

technical field [0001] The invention belongs to the field of construction methods of prefabricated reinforced concrete floor slabs in house construction engineering, and in particular relates to a method for integral splicing of prefabricated reinforced concrete floor slabs within a span. Background technique [0002] Using prefabricated floor slabs to build a floor plan is a simple, fast, and highly industrialized construction method. However, traditional prefabricated floors are mostly one-way stress slabs, and the construction method inevitably produces gaps, which are easy to crack and cause floor leakage. , affecting the use of interior decoration and architecture. In recent years, with the development of construction industrialization and housing industrialization, more and more prefabricated monolithic structures are used in the construction of residential buildings. The floor slabs mostly use prefabricated reinforced concrete laminated slabs, prefabricated reinforced...

AI Technical Summary

Problems solved by technology

The traditional method is to weld or mechanically connect the steel bars at the bottom of the slab at the joints, and realize the connection of the prefabricated reinforced concrete floor slabs through the post-cast concrete connection belt, so as to achieve the purpose of becoming a two-way slab. However, this method is difficult to construct, labor-intensive, time-consuming and expensive.
