Description
Technical field
The utility model belongs to the realm of building construction, is specifically related to a kind of prestressed concrete ribbed thin slab bidirectional laminated slab superstructure.
Background technology
Prefabricated superstructure has that industrialization degree is high, component quality easily ensures, speed of application is fast, save the advantage such as template and supporting, but globality is poor, and antidetonation, crack resistance are poor, particularly become cureless common quality defect along plank split.Full cast-in-situ floor has good integrity, advantage that anti-seismic performance is good, but reinforcing bar, formwork and formwork supports material usage are many, and make and install complicated, the amount of labour used is large, and long construction period, is unfavorable for organizing suitability for industrialized production.Along with construction work new technology, the promoting more and more widely of new technology, the Development Policy core of country also more and more lays particular emphasis on energy-saving and emission-reduction, reduces energy consumption, environmental protection.
Utility model content
According to above the deficiencies in the prior art, the utility model provides a kind of prestressed concrete ribbed thin slab bidirectional laminated slab superstructure, overcomes traditional Prefabricated superstructure globality poor, antidetonation, crack resistance are poor, particularly along the common quality defect problem of plank split, and easy construction, consumption is few.
A kind of prestressed concrete ribbed thin slab bidirectional laminated slab superstructure described in the utility model, comprise prestressed thin slab, the longitudinal stationary distribution of prestressed thin slab upper surface has rectangular fin, every bar rectangular fin equidistantly offers strip hole, and strip hole location on each bar rectangular fin is corresponding, laterally be interspersed with transverse reinforcement along strip hole, prestressed thin slab upper surface has built concrete, and covers rectangular fin completely.
The strip hole that rectangular fin is offered can form shearing resistance keyway after concreting, can increase the shear strength of concrete and its bonding surface.
Wherein, preferred version is as follows:
Prestressed thin slab upper surface is preferably nature matsurface or netted impression matsurface, can increase the shear strength of concrete and prestressed thin slab bonding surface.
Preferably have broken line cracking resistance reinforcing bar along prestressed thin slab genesis analysis, broken line cracking resistance reinforcing bar is positioned at transverse reinforcement bottom, and by iron wire and the colligation of transverse reinforcement phase.Fold-line-shaped cracking resistance reinforcing bar effectively prevent along plank split, improves the globality of structure, must ensure that position is accurate, fixation.
The beneficial effect that the utility model has is: adopt prestressed thin slab with ribbing, cast-in-situ concrete overlapping layers, add the novel cast in place and precast construction that transverse reinforcement combines, this superstructure has good ductile characteristic, rigidity is larger, stress performance is good, the prestressed thin slab with ribbing adopted forms inverted T shape structure, improve the bearing capacity and stiffness of prefabricated units, decrease template and support consumption, improve speed of application.The utility model effectively improves bearing capacity and the globality of structure, improves efficiency of construction, decreases template and supports consumption, ensure that construction safety, prevent along common quality defects such as plank splits, reduce construction costs, achieve good economic benefit and social benefit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1, prestressed thin slab 2, rectangular fin 3, transverse reinforcement 4, broken line cracking resistance reinforcing bar 5, concrete.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further.
Embodiment 1:
As shown in Figure 1, a kind of prestressed concrete ribbed thin slab bidirectional laminated slab superstructure, comprise prestressed thin slab 1, the longitudinal stationary distribution of prestressed thin slab 1 upper surface has rectangular fin 2, every bar rectangular fin 2 equidistantly offers strip hole, and strip hole location on each bar rectangular fin 2 is corresponding, is laterally interspersed with transverse reinforcement 3 along strip hole, prestressed thin slab 1 upper surface has built concrete 5, and covers rectangular fin 2 completely.
The strip hole that rectangular fin 2 is offered can form shearing resistance keyway after concrete 5 is built, and can increase the shear strength of concrete and its bonding surface.
Prestressed thin slab 1 upper surface is nature matsurface, can increase the shear strength of concrete 5 and prestressing force 1 bonding surface.
Have broken line cracking resistance reinforcing bar 4 along prestressed thin slab 1 genesis analysis, broken line cracking resistance 4 is positioned at transverse reinforcement 3 bottom, and by iron wire and the colligation of transverse reinforcement 3 phase.Fold-line-shaped cracking resistance reinforcing bar 4 effectively prevent along plank split, improves the globality of structure, must ensure that position is accurate, fixation.
This structure adopts prestressed thin slab 1 with ribbing, cast-in-situ concrete 5 overlapping layers, add the novel cast in place and precast construction that transverse reinforcement 3 combines, this superstructure has good ductile characteristic, rigidity is larger, stress performance is good, the prestressed thin slab with ribbing 1 adopted forms inverted T shape structure, improve the bearing capacity and stiffness of prefabricated units, decrease template and support consumption, improve speed of application.The utility model effectively improves bearing capacity and the globality of structure, improves efficiency of construction, decreases template and supports consumption, ensure that construction safety, prevent along common quality defects such as plank splits, reduce construction costs, achieve good economic benefit and social benefit.
