Abstract
The utility model relates to a profiled steel sheet and concrete composite floor which sequentially comprises a profiled steel sheet layer, a reinforcing rib welded mesh layer and a concrete cast-in-situ layer from bottom to top. The profiled steel sheet layer is provided with a plurality of parallel grooves. The reinforcing rib welded mesh layer comprises horizontal reinforcing ribs and lengthwise reinforcing ribs, the horizontal reinforcing ribs are arranged on the grooves, and every two grooves are provided with one horizontal reinforcing rib. The strength of the reinforcing rib welded mesh layer is 210-380N/mm<2>, and the thickness of the profiled steel sheet layer is 20mm-38mm. The profiled steel sheet and concrete composite floor is conveniently connected with steel girders, when a composite flat girder floor system is formed, effective use clearance of a building is increased, meanwhile fire-proof and antiseptic capacity of the steel girders is improved, and overall stability and local stability of the steel girders are ensured. Construction has the advantage of being free of a template, the template is saved, construction progress is quickened, self weight of the structure is relieved, and overall manufacturing and construction cost of engineering is reduced.
Description
Technical field
The utility model relates to a kind of composite floor, specifically relates to a kind of profiled sheet and concrete combined floor, is applicable to the structure field.
Background technology
Key issues such as reinforced concrete structure is one of main architecture structure form of China, but the raising that requires along with building height and anti-seismic performance, and its seismic bearing capacity and deformation performance are relatively poor make the application of reinforced concrete structure be subjected to more restriction.In recent years, the development of reinforced concrete composite structure brings many superiority, more and more bearing units that adopt profiled sheet with ribbing as the building floor system in combining structure.Concrete compressive property is good and tensile property is poor, though the intensity of steel tension and compression is higher, pressurized depends on stability bearing capacity often, and intensity can not make full use of.Existing composite floor can not be given full play to the strong point of concrete and these two kinds of materials of steel.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of profiled sheet and concrete combined floor, concrete and two kinds of properties of materials combinations of profiled sheet are made its co-operation, give play to good stress performance and deformability, formed the light-duty floor system effective, that economy is high.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of profiled sheet and concrete combined floor, be followed successively by profiled sheet layer, welded steel fabric layer and concrete cast-in-situ layer from the bottom up, described profiled sheet layer is provided with some the grooves that are parallel to each other, described welded steel fabric layer comprises transverse reinforcement and longitudinal reinforcement, described transverse reinforcement is arranged on the groove, and places one on per two grooves with transverse reinforcement.
The intensity of described welded steel fabric layer is 210-380 N/mm
2
The intensity of described welded steel fabric layer is 360 N/mm
2
The thickness of described profiled sheet layer is 20-38mm.
The thickness of described profiled sheet layer is 35mm.
The beneficial effects of the utility model are as follows:
1, composite floor of the present utility model can reduce thickness of slab and reduce dead load, has reduced cost basic, beam and column, and this advantage in high level and superelevation layer is remarkable; Composite floor and girder steel are easy to connect, when forming the combination flat beam building cover, can increase building and effectively use headroom, have improved the fire retardant anticorrosion ability of girder steel simultaneously, and the resistance to overturning of girder steel and local stability are guaranteed.
2, the construction of composite floor of the present utility model has the advantage of exempting from a template, has not only saved template, has also accelerated construction speed, has reduced engineering overall cost and construction cost.
3, the utility model profiled sheet and concrete combined floor, ductile performance is superior, uses particularly favourable in the antidetonation area; After hardening of concrete, steel plate serves as tensile reinforcement in the positive bending moment district, and the reinforcing bar that has reduced in amount of reinforcement and the site operation is shaped and the colligation expense.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Wherein, 1 is that concrete cast-in-situ layer, 2 is that welded steel fabric layer, 21 is that transverse reinforcement, 22 is that longitudinal reinforcement, 3 is that profiled sheet layer, 4 is groove.
The specific embodiment
Below in conjunction with specific embodiment the utility model is further described, but protection domain of the present utility model is not limited to this.
As shown in Figure 1, profiled sheet of the present utility model and concrete combined floor, be followed successively by profiled sheet layer 3, welded steel fabric layer 2 and concrete cast-in-situ layer 1 from the bottom up, the profiled sheet layer is provided with some the grooves that are parallel to each other 4, welded steel fabric layer 2 comprises transverse reinforcement 21 and longitudinal reinforcement 22, transverse reinforcement 21 is arranged on the groove 4, and places a transverse reinforcement 21 on per two grooves 4, and promptly a groove 4 is put a transverse reinforcement 21 at interval.
Profiled sheet of the present utility model and concrete combined floor, the intensity of its welded steel fabric layer 2 are 210-380 N/mm
2, the thickness of profiled sheet layer 3 is 20-38mm.
For every performances such as the ductility that makes the utility model profiled sheet and concrete combined floor, deadweight reach best, the intensity of welded steel fabric layer of the present utility model is 360 N/mm
2, the thickness of profiled sheet layer is 35mm.
Composite floor of the present utility model can reduce thickness of slab and reduce dead load, has reduced cost basic, beam and column, and this advantage in high level and superelevation layer is remarkable; Composite floor and girder steel are easy to connect, when forming the combination flat beam building cover, can increase building and effectively use headroom, have improved the fire retardant anticorrosion ability of girder steel simultaneously, and the resistance to overturning of girder steel and local stability are guaranteed; Construction has the advantage of exempting from a template, has not only saved template, has also accelerated construction speed, has reduced engineering overall cost and construction cost.
The foregoing description only is used to the inventive concept of the present utility model of explaining, but not to the qualification of the utility model rights protection, allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should fall into protection domain of the present utility model.
