Problems solved by technology

This kind of connection has less restraint on the rotation of the floor, and the integrity of the floor is not good. The damage under the earthquake is more serious, and it is not easy to repair.

Embodiment Construction

[0021] The fully prefabricated reinforced concrete floor system includes a beam 1, a prefabricated slab 2, and the front and rear ends of the prefabricated slab 2 are respectively overlapped with the beams located at the front and rear ends of the prefabricated slab 2. The prefabricated slab 2 includes side slabs 21 and ordinary slabs. 22 and the middle plate 23, and one side of the side plate 21 is overlapped with the beam, and the other side of the middle plate 23, the ordinary plate 22 and the side plate 21 are overlapped in turn, characterized in that the beam 1 is a lug beam , The middle board 23, the ordinary board 22 and the side board 21 are all match-and-match boards, and the two sides of the mid-board 23 are both lower and lower, and the two sides of the ordinary board 22 are respectively upper and lower. The other side of the side plate 21 is an upper groove, the prefabricated plates are connected by a plate-plate connector 4, and the prefabricated plates 2 and the be...

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 design and construction of floor structures for buildings, in particular to the field of fully prefabricated concrete floor systems. Background technique [0002] At present, the prefabricated concrete floor system mainly includes the assembled monolithic floor system and the laminated floor system, that is, a kind of floor structure in which steel mesh is laid on the precast slab and the concrete is poured afterwards. All belong to the "wet" floor system. . The prefabricated slabs in the assembled monolithic floor are mostly prefabricated pre-stressed slabs; the prefabricated slabs in the laminated floor cover commonly include hollow slabs, grooved slabs and sandwich panels. The existence of post-pouring concrete for "wet" floors retains the shortcomings of cast-in-place concrete floors. It requires a lot of wet work and site work, requires a certain amount of formwork and support, complex operations, difficult to ens...
