One-way dense rib cavity floor system module for steel structure and construction method of one-way dense rib cavity floor system module

Abstract

The invention discloses a one-way dense rib cavity floor system module for a steel structure and a construction method of the one-way dense rib cavity floor system module, and relates to the technical field of fabricated buildings. The one-way dense rib cavity floor system module for the steel structure is integrally formed by prefabricating at least two parallel profile steel dense rib beams, at least one bottom plate, at least one cavity component and at least one integrated pipeline piece; profile steel of the profile steel ribbed beams is connected with steel bars of the bottom plate and is cast and tamped into a whole through concrete, the integrated pipeline piece is fixed to the upper face of the bottom plate, and the cavity component is located between the two parallel profile steel ribbed beams and fixed to the upper face of the bottom plate; according to the one-way dense rib cavity floor system module for the steel structure, the construction time can be saved, formwork erecting is not needed, the number of formwork erecting supporting rods is reduced, the construction period is shortened, and the cost can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, in particular to a one-way dense rib cavity floor module for a steel structure and a construction method thereof. Background technique [0002] At present, in addition to cast-in-place concrete floor slabs, only steel truss floor decks are used in the application of steel structure floors. Compared with the steel truss floor deck and cast-in-place concrete floor, the amount of formwork and cast-in-place concrete has not been reduced, but the number of horizontal formwork has been reduced. Therefore, it is not a true prefabricated construction method; neither can save The construction period cannot reduce labor, especially the workload of wet work is also a lot, and the cost cannot be saved. In reinforced concrete structures, laminated floors are widely used. Due to the relatively small span and relatively large floor weight, the amount of wet work on the laminated slabs is also n...

Problems solved by technology

For example, a utility model patent (Patent No. ZL200420103009.7) for a cast-in-situ concrete concealed rib plateless hollow floor discloses that the combination of prefabricated cavity components and cast-in-place concrete steel dense rib beams forms a concrete dense rib cavity. The technical scheme of the cavity floor, but this is a cast-in-place steel ribbed beam and cast-in-place slab method, which does not belong to the prefabricated building; another example is the invention patent of a two-way densely ribbed cavity floor and its construction method (Patent No. ZL201310490037.2) discloses a technical scheme for forming a densely ribbed cavity floor by combining profiled steel densely ribbed beams and a prefabricated reinforced concrete slab. Although this type of floor and method can be included in prefabricated building technology, its construction The method is relatively complicated, and there is no reliable connection between the prefabricated floor and the steel beam
