Description
Technical field
The utility model relates to building field more particularly to a kind of unidirectional prestressing force two-way reinforced concrete laminated floor slabs.
Background technique
There are superposed surfaces whether to be furnished with two kinds of situations of shear reinforcement in actual design for traditional laminated floor slab.Do not configure shearing resistance
The superposed surfaces of reinforcing bar have certain requirement to the specific practice and roughness on prefabricated panel surface, in prefabricated panel actual fabrication
It constructional difficulties and is difficult to quantify to guarantee, construction processing is improper, floor span is larger or flooring bears accidental load or long-term lotus
When load, there is the possibility destroyed suddenly, the application range of floor is restricted, and when design needs using biggish safety coefficient；
The superposed surfaces reliability for configuring shear reinforcement is higher, during loading, even if there is crack along superposed surfaces, will not break immediately
It is bad, there is apparent omen, belong to ductile fracture, but there is transport, stack, construct the problems such as inconvenient.Prefabricated reinforced concrete
Sandwich plate using steel bar girder formula structure as shear connector, the integral working shadow of the spacing of steel bar girder to battenboard
Sound is larger, excellent structural behaviour can be obtained when spacing is smaller, but steel using amount is too big, economy is poor.Therefore engineering skill
Art personnel need a kind of cost-effective reinforced concrete slab.
Utility model content
The purpose of this utility model is that in view of the drawbacks of the prior art and insufficient, provide that a kind of unidirectional prestressing force is two-way to match
Reinforced concrete laminated floor slab, so that the building that engineers and technicians can be more economical and practical with design-build.
To realize the above-mentioned technical purpose, the technical solution adopted in the utility model is: a kind of unidirectional prestressing force two-way reinforcement
Reinforced concrete slab, including be made of prefabricated bottom plate with ribbing, overlapping concrete layer, deformed bar；The prefabricated bottom with ribbing
Overlapping concrete layer is poured on plate, centre setting deformed bar applies prestressing force, forms complete pre-stress floor structure；Institute
Stating prefabricated bottom plate with ribbing includes bottom plate with ribbing, perforation reinforcing bar, fold-line-shaped piece cracking resistance reinforcing bar, wherein bottom plate once-cast with ribbing
Molding, and bottom plate and rib of slab are reserved with several holes；Perforation reinforcing bar is arranged by hole between the rib of slab of the bottom plate with ribbing
Through being connected and fixed, which is arranged vertically with rib of slab, and fold-line-shaped piece cracking resistance reinforcing bar, the folding are additionally provided between rib of slab
Linear piece cracking resistance reinforcement welding is fixed on perforation reinforcing bar, and along the elongated arrangement of rib of slab length direction；The prefabricated bottom with ribbing
Plate upper has overlapping concrete layer；The deformed bar passes through in bottom plate reserving hole, and applies prestressing force, and formation is answered in advance
Power floor construction.
The beneficial effects of the utility model are: effectively reducing the damage of superposed surfaces, enhance the integral working of superimposed sheet,
The ultimate load for improving superimposed sheet and the recoverable force performance after unloading are conducive to the repair of floor after shake；Solution finishes
Close the disadvantage that muscle is unfavorable for construction, moreover it is possible to guarantee the reliability and stability of shear bond strength ability；Enhancing is folded to a certain extent
The recoverable force performance of plywood improves the cooperative bearing performance of such laminated floor slab overlapping layers and prefabricated panel, guarantees overlapping examination
Part gives full play to its ultimate bearing capacity.
Detailed description of the invention
Attached drawing described herein is to be used to provide a further understanding of the present invention, and constitutes one of the application
Point, but do not constitute the restriction to the utility model.
Fig. 1 is the structural schematic diagram of the utility model.
Wherein, 1 is prefabricated bottom plate with ribbing, and 1-1 is bottom plate with ribbing, and 1-11 is bottom plate, and 1-12 is rib of slab, and 1-2 is perforation steel
Muscle, 1-3 are fold-line-shaped piece cracking resistance reinforcing bar, and 2 be overlapping concrete layer, and 3 be deformed bar.
Specific embodiment
In conjunction with attached drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of unidirectional prestressing force two-way reinforced concrete laminated floor slab, the floor mainly by: it is prefabricated with ribbing
Bottom plate 1, overlapping concrete layer 2, deformed bar 3 form；Overlapping concrete layer 2 is poured on prefabricated bottom plate with ribbing 1, centre is set
It sets deformed bar 3 and applies prestressing force, form complete pre-stress floor structure；Prefabricated bottom plate with ribbing 1 includes bottom plate 1- with ribbing
1, perforate reinforcing bar 1-2, fold-line-shaped piece cracking resistance reinforcing bar 1-3, wherein bottom plate one-time cast-forming with ribbing, and bottom plate 1-11 and rib of slab
1-12 is reserved with several holes；Perforation reinforcing bar 1-2 is arranged by hole between the rib of slab 1-12 of bottom plate 1 with ribbing and runs through connection admittedly
Fixed, the perforation reinforcing bar 1-2 and rib of slab 1-12 is arranged vertically, and fold-line-shaped piece cracking resistance reinforcing bar 1-3 is additionally provided between rib of slab 1-12,
Fold-line-shaped piece cracking resistance reinforcing bar 1-3 is weldingly fixed on perforation reinforcing bar 1-2, and along the elongated arrangement of rib of slab 1-12 length direction；
Prefabricated 1 upper of bottom plate with ribbing has overlapping concrete layer 2；Deformed bar 3 passes through in bottom plate 1-11 reserving hole, and applies pre-
Stress forms pre-stress floor structure.
The technology contents and technical characteristic of the utility model have revealed that as above those skilled in the art still may base
In the utility model teaching and make the replacement and modification without departing substantially from the utility model in essence, therefore, the utility model protection
Range is not limited to the revealed content of embodiment, also includes various replacements and modification without departing substantially from the utility model in essence.
