Abstract
A fish-bellied type prestressed concrete two-way composite slab relates to a structural element and comprises a concrete thin plate spiral rib steel wire, a fish-bellied type reinforcement cage and a concrete support; the fish-bellied type prestressed concrete two-way composite slab is characterized in that the bottom plate of the composite slab is a prestressed concrete bottom plate, and the upper part thereof is the fish-bellied type reinforcement frame; and the interior of the composite slab is provided with the concrete support. A transverse bottom rib and an upper part support steel bar are laid on the slab surface of the composite slab. Or line pipes in a cast-in-situ concrete slab are laid in the composite slap. The two-way composite slab is in line with the theory advocated in China that the building realizes the idea of building industrialization 'three plates' (wallboard, floorslab and roof plate); therefore, the two-way composite slab has the application and extension significance. The fish-bellied type prestressed concrete two-way composite slab can be applied to roof boarding and floorslab for industrial and civil building.
Description
Technical field
The present invention relates to a kind of building unit, particularly relate to a kind of base plate of prestressed concrete bidirectional laminated slab for building.
Background technology
Adopt prefabricated concrete hollow slab or solid thin plate to have monolithic and fabricated two-fold advantage as the assembled integral superimposed sheet of base plate, speed of application is fast, save template, reduce cost, good integrity etc., at home and abroad is used widely.Depth of section was very big when traditional prefabricated panel was often manufactured for the rigidity problem that solves itself, was difficult to be designed to two-way floor.
Summary of the invention
The objective of the invention is to a kind of base plate that proposes the prestressed concrete bidirectional laminated slab, be used for the roof panel and the floor of industry and civilian construction.The building that China advocates of meeting this bidirectional laminated slab realizes the theory of industrialization of construction industry " three blocks of plates " (wallboard, floor, roof panel), therefore has the meaning of applying.
The objective of the invention is to be achieved through the following technical solutions:
Fish-bellied type prestressed concrete two-way composite slab, include concrete thin plates helix rib steel wire, fish-bellied type cage of reinforcement and concrete support, its described superimposed sheet base plate is the prestressed concrete base plate, and top is the fish-bellied type cage of reinforcement, is provided with concrete support in the plate.
Described fish-bellied type prestressed concrete two-way composite slab, its described superimposed sheet plate face is laid muscle of the horizontal end and upper seat reinforcing bar.
Described fish-bellied type prestressed concrete two-way composite slab, its described superimposed sheet or lay pipeline in the cast-in-place plate.

The specific embodiment
The present invention is described in detail with reference to the accompanying drawings.
The present invention is made up of with the fish-bellied type cage of reinforcement 3 and the plate inner concrete support 4 on top concrete thin plates 1, helix rib steel wire 2.To calculate during combination compressor wire put open and during superimposed sheet concreting, the intensity of fish-bellied type cage of reinforcement and stable, it is met the requirements.
The making of superimposed sheet should guarantee the position and the anchoring of fish-bellied type cage of reinforcement:
The prestressed concrete base plate adopts the pre-tensioning system construction, and the quantity of presstressed reinforcing steel can be by the designing requirement adjustment.The fish-bellied type cage of reinforcement is accurately in place, and there are enough anchorage lengths the end of skeleton reinforcing steel bar in base plate.
The erection procedure of superimposed sheet should guarantee the stress performance and the workmanship of this structural system:
The hard frame formwork of bearing, absolute altitude, the axis of inspection wall or beam are proofreaied and correct backing positions.The superimposed sheet hoisted in position is laid muscle of the horizontal end and upper seat reinforcing bar by designing requirement.Press the design drawing pipeline installation.
This plate is made up of with the fish-bellied type cage of reinforcement 3 and the plate inner concrete support 4 on top concrete thin plates 1 helix rib steel wire 2, and the effect of template when concrete thin plates plays floor slab construction can freely be laid the transverse bottom reinforcing bar at the plate face, realizes the bidirectional stress of superimposed sheet.Also can freely lay the pipeline in the cast-in-place plate, make things convenient for the construction and the management of other specialty.Prestressed concrete bidirectional laminated slab base plate of the present invention can be used for the roof panel and the floor of industry and civilian construction.
Base plate of the present invention is a prestressed concrete plate, and the fish-bellied type cage of reinforcement is adopted on top.The present invention adopts high-strength helix rib steel wire to apply behind the prestressing force longitudinal stress reinforcing bar as superimposed sheet, can significantly reduce the steel using amount of concrete floor, the effect of template when the concrete floor of 40～50mm can play floor slab construction, can freely lay the transverse bottom reinforcing bar at the plate face again, realize the bidirectional stress of superimposed sheet.The fish-bellied type cage of reinforcement on top then can bear the plate top pulling force when applying prestressing force, can increase the rigidity of superimposed base plate again, to guarantee superimposed sheet base plate safety in construction, transportation, hoisting process.Because cage of reinforcement is only arranged at top, can also freely lay the pipeline in the cast-in-place plate, make things convenient for the construction and the management of other specialty.The building that China advocates of meeting this bidirectional laminated slab realizes the theory of industrialization of construction industry " three blocks of plates " (wallboard, floor, roof panel), therefore has popularizing application prospect preferably.
