Abstract

The invention discloses a totally-prefabricated assembling type reinforced concrete floor system which consists of girders, prefabricated slabs, girder-slab connecting pieces, and slab-slab connecting pieces. The invention is characterized in that: the prefabricated girders are cornice girders, and the prefabricated slabs are matchboards; the prefabricated slabs are fixedly connected by the girder-slab connecting pieces after being arranged on the prefabricated girders; and the prefabricated slabs are fixedly connected by the slab-slab connecting pieces after being lap-jointed with each other. The prefabricated slabs can be prefabricated prestressed concrete cored slabs, superimposed slabs or other flat slabs. The invention realizes the bidirectional force bearing performance of the unidirectional prefabricated slabs and the four-edge fixed-end limiting form of the floor system, and can effectively meet the requirement for large span and heavy load; moreover, belonging to a totally-assembled system, the invention has the characteristics of less field operation, high construction speed, good earthquake resisting performance, and obvious effects of energy saving and environmental protection.

Description

Technical field [0001] The invention relates to the field of floor structure design and construction for buildings, in particular to the field of fully prefabricated assembled concrete floor systems. Background technique [0002] At present, the prefabricated concrete floor system mainly includes the assembled integral floor system and the laminated floor system, that is, a floor structure in which steel mesh is laid on the prefabricated slab and concrete is poured afterward, all of which belong to the "wet" floor system. . The prefabricated slabs in the assembled integral floor are mostly prefabricated prestressed slabs; the common prefabricated slabs in the composite floor are hollow slabs, grooved slabs and sandwich slabs. The existence of post-cast concrete in the "wet" floor retains the shortcomings of cast-in-place concrete floors, requires a lot of wet work and on-site work, requires a certain amount of formwork and supports, complex operations, difficult to guarante...
