[0002] At present, prefabricated PC structures are used more and more widely, but traditional PC prefabricated structural beam-slab connections adopt superimposed cast-in-place rigid connections. For small prefabricated PC structures, it is a wet construction, and it is inconvenient to construct such small structures because it needs to be cast on site.
It affects the use of PC prefabricated structures in this type of project

The invention relates to a fast-constructed beam and slab connecting structure and a construction method thereof. A nut screw of the connecting structure penetrates through a ladder hole formed in a prefabricated reinforced concrete slab and is screwed into an embedded bolt sleeve. Embedded bars are welded to an embedded steel plate, the embedded steel plate is located between an upper ladder hole body and a lower ladder hole body of the ladder hole, and a strip-shaped bolt hole formed in the embedded steel plate exactly faces the ladder hole. The construction method comprises the steps that the embedded bolt sleeve is embedded into a prefabricated reinforced concrete beam, and vertical arrangement of the embedded bolt sleeve is ensured; the embedded steel plate and the embedded bars are embedded into the prefabricated reinforced concrete slab, the strip-shaped bolt hole is formed in the embedded steel plate, and then the nut screw is vertically screwed into the embedded bolt sleeve; anticorrosion treatment is carried out on exposed steel members, and a concave opening of the ladder hole is filled with waterproof asphalt factice. According to the scheme, the safety of a structural system can be effectively guaranteed, and fast construction of later maintenance and replacement can be facilitated.
Description
technical field [0001] The invention belongs to the field of architectural design and construction, in particular to a fast-constructed beam-slab connection structure and a construction method thereof. Background technique [0002] At present, prefabricated PC structures are used more and more widely, but traditional PC prefabricated structural beam-slab connections adopt superimposed cast-in-place rigid connections. For small prefabricated PC structures, it is a wet construction, and it is inconvenient for such small structures to be cast on site. It affects the use of PC prefabricated structures in this type of project. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a replaceable connection node that fully meets the requirements of the beam-slab hinge, can effectively ensure the safety of the structural system, and can be maintained and replaced in the later period. The rapid construction of the beam-slab c...
