Abstract

The air-bag form for placing concrete is characterized by that its external form is cublic box, and its interior possesses several circular air-bag inner linings; after the high-pressure air is charged, the form shape is stable, and the entire form does not change, if its a part is subjected to pressure intensity. After the air is pumped out, it is soft., and can be folded, and the wall poured by using said air-bag form is level and smooth. As compared with traditional form, it is light in weight, small in volume for handling, convenient for mounting and dismounting, and can greatly reduce building cost and shorten construction period.

Description

Air bag form for building

The invention belongs to building large formwork construction field.

The cast-in-place house of large form is to adopt large-scale template, and in corresponding construction machinery, by rational construction organization, with industrial mode of production cast in situs steel concrete.It is the industrialized important system of novel building, and is not only a kind of common templates individual works.The present large form that adopts in the large formwork construction method that occurs, all by inner rigid trestle outward thick china form or the rigidity sheet material that fuses of inner principal rod and panel.For example the template of introducing among patent documentation CN2049653U, the CN1038268C all is that inner rigid trestle and panel are formed.Have that volume is big, weight is big, carrying, install, the time-consuming problem of taking a lot of work of dismounting.

The purpose of this invention is to provide a kind of in light weight, volume is little, is convenient to the template that mounts and dismounts, carries.

So the present invention possesses above advantage, be because break through the notion of template rigidity structure in design first, adopt flexible airbag structure.The profile of air bag form is a cube, and specification is the same big with the room space size that will build, and it is that internal mold as a room uses, and it is the trapezoidal geometrical body that waits that its profile also can design needs according to construction drawing.The inside of air bag form is that a plurality of spheroids or cylindrical air bag liner are formed, for example shown in accompanying drawing 1,2,3 sectional drawings.

The liner air bag fills gases at high pressure, makes the integral gasbag template can bear respective external pressure and indeformable.Because the air bag liner adopts the very big material (for example glass fiber rubberized fabric) of stretch modulus, so when pressure was born in the air bag part, the change of shape of air bag was also very small, balloon surface is smooth smooth, and the metope of being built is also smooth smooth, need not to plaster.

High-quality gesture of the present invention: 1, remove the steel bracket of heaviness of traditional large form or principal rod and adopt the high-pressure gasbag liner, formwork integral weight is alleviated greatly.When 2, this air bag form being installed, a room only needs once the inflation of position, school, and does not need position, traditional rigidity template block-by-block school to connect.Only need start shooting during dismounting and bleed automatically, and empty air bag form is collapsible, convenient carrying, traditional rigidity template then needs block-by-block to take apart, all needs Special Hoisting Equipment when dismounting and carrying, and speed is slow, the cost height.By contrast, this patent method has been saved the time greatly, has improved benefit.

The e-mould

Embodiment: now need manufacture specification and be 2.8 * 4 * 5 air bag form, the air valve position is at 2.8 * 4 meters side diagonal crossover location.Maximum pressure is 4.8 tons/square metre when at first smashing according to 2.8 meters height gauge concretings shake, is multiplied by safety factor, determine to hold in the air bag air pressure at last and be the 7.5-10 ton/square metre.According to template specification, (Fig. 1-a), 134 centimetres (Fig. 1-b), 44.5 centimetres (Fig. 1-c), 25.2 centimetres (the Cylinder liner air bag of the two ends sphere of Fig. 1-d) is formed to determine mainly to be respectively 274 centimetres by diameter by air bag form liner air bag at last.Material adopts non-twist plain weave rubberized fabric to make, and presses in holding greater than 10 tons/square metre, and the air bag length overall must not change above 10 millimeters between interior pressure is from 2 tons to 7 tons, and diameter must not surpass 0.2%.The liner air bag after the assay was approved, in square five Tooling Warehouses that do not have an end face (the dies cavity specification should be 2.78 * 3.97 * 4.97 meters), the liner air bag that air pressure is charged to 7 tons/square metre bonds together according to the order of sequence, and is shown in Figure 4 as section.The gas port of each air bag is connected side total air valve and air gauge, easing valve.Pave end face with latex, confirming to stick 8 millimeters weather surface layer rubber tiles under the smooth condition, the inverted liner pneumatophore is laid the surface layer offset plate of other 5 faces then.

Claims

1, the used internal mold in the cast-in-place house of a kind of large form, the side's of being shaped as body or other solid, specification is the same with the room of being built, surfacing is smooth, body of wall and end face are disposable cast-in-place during construction, it is characterized in that: integral mold plate is an inflatable bladder, fills dimensionally stable behind the gases at high pressure, volume contraction after the gas bleeding and softness.

2, air bag form according to claim 1 is characterized in that: there are spheroid and cylinder air bag liner in inside.
