Pre-stressed concrete laminate of a truss of reinforced concrete with full anti-cracking ability includes a prefabricated layer (1), a laminated layer (2) above the prefabricated layer (1), the truss of reinforced concrete arranged between the prefabricated layer and the laminated layer, which consists of a lower-chord reinforcement (3), an upper-chord reinforcement (5) and a web member. The lower-chord reinforcement (3) is arranged below the prefabricated layer (1). The upper-chord reinforcement (5) is arranged in the laminated layer (2). A lower part of the laminated layer is provided with a steel reinforcement in another direction (4) inter-distributing with the lower-chord reinforcement. The laminated layer is provided with an additional reinforcement inter-distributing with the lower-chord reinforcement in the same plane, forming a network structure. The lower part of the prefabricated layer is provided with a pre-stressed steel reinforcement (8) running parallel to the lower-chord reinforcement. The lower-chord reinforcement (3), the pre-stressed steel reinforcement and the steel reinforcement in another direction (4) in the same plane form a network structure.

Description

Prestressed Concrete Superimposed Sheet Of Steel Bar Truss

Technical field

The utility model relates to the floor in a kind of building structure, especially a kind of superimposed sheet.

Background technology

It is several that the type of floor mainly contains precast plate, cast-in-place plate, superimposed sheet, Profiled Steel Sheet and Concrete Composite Floor etc. at present.Though wherein the precast plate speed of application is fast, the flooring integral rigidity is poor, and earthquake is serious, remains in antiseepage, anti-leakage problem, influences it and applies; Though cast-in-place plate integral rigidity is good, need carry out the form work engineering and the reinforced bar engineering of lengthy and tedious complexity, engineering cost height, long construction period; Though profiled sheet one concrete combined floor speed of application is fast, expense height, and soffit out-of-flatness often need furred ceiling to handle.The shortcoming that existing superimposed sheet exists is: 1, the superposed surfaces between preformed layer and the overlapping layers need be carried out the strictness processing; 2, suitable span is less; 3, reinforcing bar binding is loaded down with trivial details, influences construction speed.

The Truss-type Composite Plate of the applicant's No. 200420022036.1 Chinese utility model patents of ZL has overcome the defective of described existing superimposed sheet, but being the preformed layer bottom of this superimposed sheet, its weak point only have the reinforcing bar purlin lower edge muscle of longitudinal stress to reticulate structure to reinforcing bar in same planar shaped with another, make the reasonable Arrangement of longitudinal stress reinforcing bar produce certain difficulty, having to change the problem that the steel bar girder spacing causes the increase expense and prolongs the processing duration for reasonable Arrangement longitudinal stress reinforcing bar in some cases, and the crack resistance of superimposed sheet can not fully guarantee.

Summary of the invention

The utility model is solving too strictness of existing superimposed sheet superposed surfaces processing, it is little to be fit to span, reinforcing bar binding is loaded down with trivial details when influencing problems such as construction speed, solve the problem that superimposed sheet longitudinal stress reinforcement placement is reasonable inadequately and crack resistance can not fully guarantee, Prestressed Concrete Superimposed Sheet Of Steel Bar Truss of the present utility model is provided for this reason, this superimposed sheet longitudinal stress reinforcement placement is reasonable, and cracking resistance fully guarantees.

For addressing the above problem, the technical solution adopted in the utility model be provided with preformed layer and on overlapping layers and place described presheaf, in the overlapping layers by the lower edge muscle, the steel bar girder of muscle and the web member formation of winding up, the lower edge muscle is positioned at the preformed layer bottom, the muscle that winds up is arranged in overlapping layers, the preformed layer bottom is provided with the other direction reinforcing bar that is interspersed with the lower edge muscle, be provided with additional muscle in the overlapping layers and reticulate structure in same planar shaped with the muscle interlaced arrangement of winding up, its special character is: described preformed layer bottom is provided with the prestressed reinforcement parallel with the lower edge muscle, described lower edge muscle, prestressed reinforcement and other direction reinforcing bar reticulate structure in same planar shaped.

Steel bar girder described in the utility model can be triangular truss, snakelike truss or waveform truss.

Can in overlapping layers of the present utility model, be embedded with light filler piece or hollow section between described steel bar girder, to be fit to plate thickness when big.

Overlapping layers in the utility model is a layer of concrete.

The beneficial effect of the described Truss-type Composite Plate of the utility model Prestressed Concrete Superimposed Sheet Of Steel Bar Truss mainly shows:

1, the truss web reinforcing bar can bear the shearing on the superposed surfaces, makes preformed layer and overlapping layers that good co-operation performance be arranged, and does not need that superposed surfaces is carried out strictness and handles;

2, because steel bar girder itself has certain rigidity, adopt prestressed reinforcement that preformed layer rigidity is further improved simultaneously, promptly not can be used for constructing than large span floor so need not establish interim support;

3, wind up between muscle and the lower edge muscle and to connect,, reduce on-the-spot reinforcing bar binding workload, improve speed of application by the produce in factory steel bar girder by web member;

4, rebar spacing is arranged evenly, and concrete protective thickness is controlled easily.

5, adopt prestressed reinforcement, effectively improved the cracking resistance of plate.
