Embodiment

[0032] This example Figure 1-16 As shown, it includes steel box-type assembled units, steel plate connectors and bolts, and the upper reinforced concrete layer. The steel box-type assembly unit is composed of an upper roof plate, a web and a lower wing plate, and is a steel box-type structural unit with a hole in the bottom formed by welding and processing in the factory. After the assembly is completed, the adjacent unit webs are closely connected by bolts to form a whole, and the upper roof and lower flange plates are connected to form a densely ribbed floor structure system, which can bear the construction load of the upper reinforced concrete layer, and then form a whole with the reinforced concrete layer The dense rib composite floor structure bears loads under various combinations of working conditions during the service period. The top plate, web plate and lower wing plate in the steel box-type assembly unit are welded by steel plates or section steel, processed into ...

Abstract

The invention discloses a combined long-span ribbed slab structure. The ribbed slab is formed by splitting steel form shells of different shapes; the frontages of the steel form shells of the different shapes are uniformly distributed with rivets (1), the sides of the steel form shells of the different shapes are connected through bolts, and the backs of the steel form shells of the different shapes are connected to form a slab plane through connecting plates (2) and bolts (3); a reinforced bar casting concrete layer (4) is paved on the plane of the slab and is closely connected with the plane of the slab to form the combined long-span ribbed slab through the uniformly distributed rivets (1). Compared with the prior art, the combined long-span ribbed slab structure provided by the invention has a few of combined components; furthermore, the combined long-span ribbed slab is processed in batches by a professional factory, good interchangeability and convenience in field splitting can be realized, the field labor capacity can be reduced, the construction period can be reduced significantly and the economic benefit can be improved; an existing wooden form can be substituted by the plane of the slab formed by splitting the steel form shells, therefore, the compressive property can be improved and the cost saving can be realized; in addition, lightening holes are formed in side plates, therefore materials can be saved and dead weight can be reduced.

Description

technical field [0001] The invention relates to a combined large-span dense-ribbed floor slab structure, which belongs to the technical field of building construction. Background technique [0002] In the design of modern public buildings, architectural functions such as cinemas, concert halls, theaters, auditoriums, etc. all require large-span floor slabs to achieve. Existing long-span floors are mostly composed of prestressed beams and ordinary beams, or composite floors of hollow floors and profiled steel plates. The existing structures have a large dead weight, and some composite floors have many types of components. Industrialized prefabrication production mode for construction market. Contents of the invention [0003] The purpose of the present invention is to provide a combined large-span dense rib floor structure. It belongs to the composite floor, and there are few types of composite components, and it is very convenient to assemble. Concrete can be poured dire...
