Abstract

The utility model relates to a common building structure, particularly a shape changing heat rolled steel bar prestressed concrete overlapped floor slab, which comprises a bottom plate which is composed of one or more steel reinforced concrete thin slabs. The upper surface of the bottom plate is covered with an overlapped concrete layer with steel bars. When the shape changing heat rolled steel bar prestressed concrete overlapped floor slab is used, the construction period can be shortened, moulds can be reduced, the engineering cost can be lowered, and the construction quality can be improved. The utility model can be widely used for industrial and civil constructions, bridges, elevated highways, etc.

Description

Distortion hot-rolled reinforced bar prestressed concrete laminated floor slab

The utility model relates to a kind of buildings in general structure, a kind of distortion hot-rolled reinforced bar prestressed concrete laminated floor slab.

The floor of present architectural usefulness, a kind of is precast plate, and this precast plate is used on the building, and its shock resistance is relatively poor.Another kind of floor is integrated poured floor, and this floor shock resistance is strong, but need use a large amount of templates when building, and is long in time limit, the cost height, and quality is difficult for stable.

The technical solution of the utility model is: a kind of distortion hot-rolled reinforced bar prestressed concrete laminated floor slab, it includes the base plate that the reinforced concrete thin plate more than one or constitutes, and covers the folded pouring concrete layer that one deck is furnished with reinforcing bar above the base plate.The above and below that constitutes the thin plate of base plate can be the plane.Constitute on the thin sheet surface of base plate can between be separated with the rib of projection.Between base plate and the folded pouring concrete layer insulating can be arranged.Reinforcing bar in the reinforced concrete thin plate of base plate can stretch out from the two ends of thin plate.Reinforcing bar in the reinforced concrete thin plate of base plate can stretch out from an end of thin plate.Reinforcing bar in the reinforced concrete thin plate of base plate also can stretch out around thin plate.

The utility model has the advantages that:, can reduce the use template in a large number owing to constitute base plate with reinforced concrete thin plate.Reinforced concrete thin plate can be prefabricated in the factory, but the reduction of erection time, and the quality of raising floor reduces cost.Cover one deck above the base plate and be furnished with the folded pouring concrete layer formation floor of reinforcing bar, make whole floor shock resistance good.

Further specify the technical solution of the utility model below in conjunction with drawings and Examples:

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is structural representations of the base plate of figure;

Accompanying drawing 3 is structural representations of embodiment 2;

Accompanying drawing 4 is base arrangement schematic diagrames of Fig. 3;

Accompanying drawing 5 is structural representations of embodiment 3;

Accompanying drawing 6 is base arrangement schematic diagrames of Fig. 5;

Embodiment 1:

With reference to accompanying drawing 1,2, by the method for making precast plate, make the prestressed reinforced concrete thin plate with low-alloy dish circle distortion hot-rolled reinforced bar as reinforcing bar and make base plate 1 (see figure 2), cloth steel mesh reinforcement or reinforcing bar 3 on base plate 1, pouring concrete is made the folded layer 2 that waters of the concrete of being furnished with reinforcing bar that covers on the base plate 1 again.

Embodiment 2:

With reference to accompanying drawing 3,4, by the method for making precast plate, make the prestressed reinforced concrete thin plate with low-alloy dish circle distortion hot-rolled reinforced bar as reinforcing bar and make base plate 1 (see figure 4), the reinforced concrete thin plate that constitutes base plate 1 has more than two and is put together, the reinforcing bar of thin plate has from the two ends of thin plate and stretches out, and also has from an end of thin plate or stretches out all around, pieced together base plate 1 after, cloth steel mesh reinforcement or reinforcing bar 3 on base plate 1, pouring concrete is made the folded layer 2 that waters of the concrete of being furnished with reinforcing bar that covers on the base plate 1 again.

Embodiment 3:

With reference to accompanying drawing 5,6, by the method for making precast plate, make the prestressed reinforced concrete thin plate with low-alloy dish circle distortion hot-rolled reinforced bar as reinforcing bar and make base plate 1 (see figure 6), be separated with the rib 4 of projection between the upper surface of the thin plate of formation base plate 1, at base plate 1 upper berth one deck insulating 5, insulation layer can be with expanded material or other material, cloth steel mesh reinforcement or reinforcing bar 3 on base plate 1 again, and pouring concrete is made the folded layer 2 that waters of the concrete of being furnished with reinforcing bar that covers on the base plate 1 again.

The making of reinforced concrete thin plate as required, to can be made into the surface have protruding rib, also can be made into the plane, can be made into reinforcing bar from an end, the two ends of thin plate or stretch out all around.
