Abstract
The utility model relates to the field of buildings, in particular to an air bag type concrete hole pre-burying device. The air bag type concrete hole pre-burying device comprises an air bag, a steel shell, a rubber jacket and an air faucet. The air bag is tightly attached to the inner surface of the steel shell. The outer surface of the steel shell is tightly attached to the inner surface of the rubber jacket. One end of the air faucet is communicated with the air bag. The other end of the air faucet stretches out of the steel shell and the rubber jacket. When the air bag expands, the steel shell and the rubber jacket are squeezed out. When the air bag exhausts, the rubber jacket contracts and the steel shell contracts. The air bag type concrete hole pre-burying device can be used circularly, saves labor cost and capital cost and protects the environment.
Description
Technical field
The utility model relates to building field, is a kind of gasbag-type concrete hole pre-embedding device specifically.
Background technology
Pre-buried device uses in embedded hole, the size of embedded hole is the size of fixing and regulation is arranged, the girth on the pre-buried device whole body just can use than embedded hole is little, the concrete preformed hole that occurs at present is all to do pretreatment with pvc pipe or other device, namely use pvc pipe to make pre-buried device, but pvc pipe is difficult to withdraw from afterwards, is being all a kind of waste aspect the energy and manpower.Sum up prior art and have following defective:
1 needs the cost manpower and financial resources to prepare material previously treated (pvc pipe);
2.PVC pipe is installed inconvenient;
3.PVC expiring, pipe needs dismounting, but some pvc pipe in the process of dismounting owing to contact too tight with concrete or other reason causes and can't normally dismantle, can only take destructive dismounting in this case, so not only waste of manpower but also increased building waste is retained in pvc pipe the quality that will affect again engineering in concrete;
4. deformation is arranged on length due to pvc pipe, use pvc pipe to do concrete embedded pore volume and easily cause hole flexural deformation.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of gasbag-type concrete hole pre-embedding device and addresses the above problem.
the technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of gasbag-type concrete hole pre-embedding device, comprise air bag, outer steel shell, rubber sleeve and valve, described air bag is close to the inner surface of described outer steel shell, the external surface of described outer steel shell is close to the inner surface of described rubber sleeve, one end of described valve is connected with described air bag, the other end of described valve stretches out described outer steel shell and described rubber sleeve, described outer steel shell and described rubber sleeve can be squeezed when described air bag expands and open, during described air bags, described rubber sleeve shrinks, described outer steel shell shrinks.
the beneficial effects of the utility model are: during use, by valve to described air bag gas injection, air bag expands and makes the size that described outer steel shell expand into to be needed, carry out pre-buried, only need when the utility model need to be withdrawn from by valve, the gas of described air bag to be discharged, outer steel shell and rubber sleeve are shunk, the utility model can be withdrawn from, both operated easy and convenient, use manpower and material resources sparingly again, can not cause building waste yet, can inject air from the place of valve to described air bag with inflator during use and can make the utility model running, air is taken from the Nature, return again in the Nature after use, the utility model has also played effect aspect environmental protection, external surface interpolation rubber sleeve at described outer steel shell can shield to described outer steel shell, also withdraws from easily and fast equipment of the present utility model, described outer steel shell is compared more shock resistance anti-vibration with original pvc pipe, and the utility model can recycle for a long time, has not only saved cost but also environmental protection.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, described outer steel shell comprises a side, and there is the joining seam seam side of described outer steel shell, and described joining seam seam connects the two ends of described outer steel shell, and the two ends of described outer steel shell are empty.
Adopt the beneficial effect of above-mentioned further scheme to be: air bag to be squeezed described outer steel shell very easily large after the expansion of being bullied, to adapt to the pre-buried demand of different hole sizes.
Further, described outer steel shell around the corner be shaped as round.
Adopt the beneficial effect of above-mentioned further scheme to be, because the outer steel shell material is hard, (side is to the excessive place at two ends) if be designed to the right angle, easily punctures described rubber sleeve around the corner, is designed to around the corner round and well avoided this problem.
Further, described air bag is close to the inner surface of described outer steel shell, and the distance at the two ends of described air bag is shorter than the distance at described outer steel shell two ends.
Adopt the beneficial effect of above-mentioned further scheme to be, prevent described air bag be bullied expand after, the two ends of described air bag are squeezed out outside described outer steel shell.
Further, the material of described outer steel shell is stainless steel.
Adopt the beneficial effect of above-mentioned further scheme to be, stainless steel can prevent from getting rusty, and stainless steel has suppleness preferably with respect to iron plate or other metal.
