Abstract
The utility model involves a vacuum-insulated concrete precast floor constructs of a prefabricating piece, whose structure consists of a reinforcing steel bar and a coordinate vacuum tube arranged on the floor. The utility model use the vacuum tube instead of a round tubular vent used in the existing floor, and provides the precast floor with a good heat preservation and thermal insulation properties by using the vacuum-insulated performance of the vacuum tube, therefore the utility model exerts the same effect as that of the heat preservation and thermal insulation layer of perlite or plantar stone. In this way, the utility model can avoid laying insulation layer used as a roof material of buildings so as to reduce the possibility of collapse and cracks of the roof and increase the effects of noise reduction accordingly.
Description
Technical field
The utility model relates to a kind of load-bearing floor that constitutes with prefabricated component basically, the concrete prefabricated floor of specifically a kind of vacuum heat-insulation.
Background technology
Available coagulation soil precast floor slab is to be laid with reinforcing bar arranged side by side (or cold-drawn tow) in floor at interval, and tube-shaped through hole arranged side by side is arranged in the middle of the floor.Concrete prefabricated cassette ceiling can reduce the integral body deadweight of floor, and pipe shape through hole also has certain support depressurization to floor itself, can reduce the slump of floor.But the thermal and insulating performance of this precast floor slab is relatively poor, when therefore using on the roof of making the house, also must lay one deck perlite or sole of the foot stone layer in the above, the house is played the effect of thermal insulation.
The utility model content
The purpose of this utility model just provides a kind of concrete prefabricated floor of vacuum heat-insulation with better heat insulating effect, to reduce or to exempt the effect of existing building top layer thermal insulation layer.
The utility model is achieved in that and is laid with reinforcing bar in the floor, also is laid with vacuum tube arranged side by side in floor.The utility model replaces pipe shape through hole in original floor with vacuum tube, utilizes the vacuum heat-insulation performance of vacuum tube, makes precast floor slab itself also have good thermal and insulating performance.Choose under the appropriate condition at vacuum tube caliber and distribute spacing, can make precast floor slab have the action effect that is equal to perlite or footplate heat preservation layer.Like this when it is made the house top layer and uses, the laying that can save top thermal insulation layer both can reduce the slump on roof thus, has reduced the fracture coefficient on roof again.When it is used as load-bearing floor of floor gap, also can be because of the existence of floor inner vacuum tube, and make the soundproof effect of floor that corresponding raising also be arranged.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, floor 1 is the long strip-board shape body, is formed by concreting.In floor 1, be laid with reinforcing bar 3 at interval, above between per two reinforcing bars, be laid with vacuum tube 2.Vacuum tube 2 and reinforcing bar 3 are the prefabricated component when watering build floor 1.
Vacuum tube 2 can be to extrude the tubular body made from cement composite material or regenerated plastics by mould, two ends shutoff then.Settle the mouth that vacuumizes of existing routine therein in the shutoff of an end, to vacuumize.The load-bearing floor that common relatively 135mm is thick, the external diameter of vacuum tube 2 can be 80-100mm, and the spacing of two vacuum tubes is advisable with 24-30mm.This layout structure can make this precast floor slab taken into account aspect load-bearing and the thermal insulation two, and realizes best matched combined.Among Fig. 1, the vacuum tube 2 on floor 1 both sides is short slightly, and the end is stayed and is shaped on the circular hole of using when being convenient to the hook lifting.
Claims (2)
1, the concrete prefabricated floor of a kind of vacuum heat-insulation is laid with reinforcing bar (3) in floor (1), it is characterized in that also being laid with in floor (1) vacuum tube arranged side by side (2).
2, the concrete prefabricated floor of vacuum heat-insulation according to claim 1, the external diameter that it is characterized in that vacuum tube (2) is 80-100mm, the spacing of two vacuum tubes is 24-30mm.
