Description
Technical field
The utility model relates to realize for construction site a kind of high strength air bag that the cast-in-place concrete hollow structure is used, is specifically related to cast-in-place concrete hollow building roof high strength air bag.
Background technology
In recent years, light material is filled the application of hollow floor structure technology, not only makes common hollow building cover reduce the structure floor height when realizing large bay, but also it is few to have the amount of concrete of use, dead load is light, and geological process power is little, and the sound isolating and heat insulating performance of structure is good.Also have simultaneously energy conservation, reduce building and use cost.Can produce good economic and social benefit, be a kind of Green environmental-protection building technology.
The packing material of realizing at present this cast-in-place concrete hollow structure superstructure generally has polystyrene (EPS) foam (column type occurred frequently, cubic type etc.) and the hollow plastic tube of all size size etc., these materials are filled in cast-in-place concrete by project organization, the hollow rate that can realize superstructure reaches 30-65%, not only the hollow light of concrete structure can be realized, the effect that energy-conserving and environment-protective reduce building costs can also be played.
Also there are some places of inconvenience in the use in these lightweights foam occurred frequently that uses in hollow building cover or hollow section etc. when bringing the concrete hollow lighting to cast-in-situ concrete, maximum be inconvenient to be exactly these materials itself be lightweight or hollow, so transportation is very inconvenient and cost of transportation is high when the cast-in-situ concrete site operation.
The utility model content
The cast-in-place concrete hollow building roof high strength air bag that technology of the present utility model is exactly inconvenient for above original packing material transportation and cost is high and propose.Its objective is the formation that can satisfy cast-in-place concrete hollow lighting structure, can solve again transportation and the use cost of this material simultaneously, concrete technical scheme is as follows.
Cast-in-place concrete hollow building roof high strength air bag comprises internal layer and skin, described internal layer be plastic sheeting make have an air-tightness plastic film gasbag with Non-return air valve; Described skin has the measure-alike reinforcement outer bag of air-tightness plastic film gasbag for what adopt that industrial fibre cloth makes with described; Being shaped as the rectangle that can fold before described high strength air bag inflation, is hollow cylindrical after inflation.A kind of cast-in-place concrete hollow building roof is made of a plurality of described high strength air bag series connection with high strength air bag assembly.
Above-mentioned cast-in-place concrete hollow building roof is with in the high strength air bag, and described internal layer is inflation film, salivation film or calendered film; Described film with material by a kind of in polyethylene (high density polyethylene (HDPE), LLDPE), polypropylene, polyester, nylon or make more than two kinds.
Above-mentioned cast-in-place concrete hollow building roof is with in the high strength air bag, and the thickness of described internal layer is 80 microns ~ 200 microns.
Above-mentioned cast-in-place concrete hollow building roof is with in the high strength air bag, take millimeter as unit, cylindrical in after described airbag aeration, described inner bladder bag size external diameter is 100,120,150,180,200,220,250,280,300,350,400,450 or 500, and cylindrical length is 500,1000,1500 or 2000.
If being inflation film, internal layer must meet the body diameter dimensional requirement by the requirement of (CECS 175: 2004).Diameter D(mm): 100, the inner plastic bag of 120,150,180 scopes employing thickness is the film of 80 microns ~ 100 microns; Diameter D(mm): 200, the inner plastic bag of 220,250,280,300 scopes employing thickness is 120 microns ~ 180 microns; Diameter D(mm): 350, the inner plastic bag of 400,450,500 scopes employing thickness is the film of 200 microns.
Above-mentioned cast-in-place concrete hollow building roof is with in the high strength air bag, and the described outer cloth that adopts is high density polyethylene (HDPE) or high density poly propylene woven cloth or high-intensity polypropylene or polyester non-woven fabric, industrial polyester fiber cloth or nylon cloth material.
Above-mentioned cast-in-place concrete hollow building roof is with in the high strength air bag, take millimeter as unit, cylindrical in after described airbag aeration, described outer reinforcement outer bag size external diameter is 100,120,150,180,200,220,250,280,300,350,400,450 or 500, and cylindrical length is 500,1000,1500 or 2000.
Above-mentioned cast-in-place concrete hollow building roof is with in the high strength air bag, described inner bladder bag with Non-return air valve adopt or homogeneity class material the same with inner layer material.
The above-mentioned cast-in-place concrete hollow building roof of the preparation power method of high strength air bag, it comprises:
Internal layer is moulded the preparation of gasbag: cut size, need to seal the thin-film material that enough 20 millimeters ~ 30 millimeters width are stayed in compound place, used for the heat-sealing sealing; The wide cut heat-sealing is taked in heat-sealing sealing place of gasbag;
The envelope system of Non-return air valve: the compound mode of double-coating of taking of the valve of Non-return air valve is heat sealed on the inner bladder bag, wherein one deck is the inner bladder bag, this layer and valve one side heat are compound, the opposite side of valve uses that to carry out clad type heat compound with the same material of inner bladder bag, and valve is coated once to guarantee the tightness of internal layer;
The outer preparation of strengthening bag of high strength air bag: press the size cutting industrial cloth supporting with the inner bladder bag, then carry out tape edge with two-wire and make.
In said method, in step a, it is 5 millimeters ~ 15 millimeters that the internal layer membrane material seals compound width.
Compared with prior art, the utlity model has following advantage and technique effect:
Cylindrical after in inflation of the high strength air bag of the utility model preparation, appearance and size meet the requirement of " cast-in-place concrete hollow building roof tecnical regulations " (CECS 175: 2004) that China Engineering Construction Standardization Association promulgates;
Air bag of the present utility model can independent single preparation and used aloned, also can contact more than two and the use of connecting with the tracheae connected mode between air bag by air bag, the air bag of series arrangement can disposable inflation be realized the light filling hollow body after design arranges; The air bag of series winding more than two can cut formation (as shown in Figure 2) by disposable;
Be exactly the sack of a rectangle before high strength air bag of the present utility model inflation, not only can fold arbitrarily, can also pile up arbitrarily, shared volume is very little, is fit to the transportation of any distance and can improve cost of transportation;
In a word, high strength air bag of the present utility model can form a kind of round column structure after inflation, carries valve and the vent plug of good seal on air bag, can bear the interior pressure of 0.1 ~ 0.3MPa after inflation in air bag and is not easy distortion.Just can form the same light hollow body of hollow tubular after inflation, fixingly just can substitute afterwards the packing material such as above-mentioned foamed polystyrene body and hollow section and realize the cast-in-place concrete hollow building roof structure.Do not inflate in transportation, inflate again when having arrived site operation.So no longer need to spend high cost of transportation as transportation foamed polystyrene body is the same with hollow section.The utility model is applicable to cast-in-place concrete hollow and hugs the structure field covered.This high strength air bag be exactly as an alternative at present the lightweight filler of cast-in-place concrete hollow building roof structure the inside and hollow section and so on a kind of use material more convenient and that transportation is lighter.
