Abstract
The invention relates to the field of building, in particular to an air bag type concrete hole pre-burying device and a manufacturing method of the pre-burying device. The method comprises the steps of: processing a piece of stainless steel by heat treatment, and bending the processed stainless steel until the size of the whole body of the stainless steel is smaller than that of a pre-burying hole to form a hollow steel shell; arranging an air bag in the steel shell, and causing the air bag to cling to the inner surface of the steel shell; arranging a rubber outer sleeve outside the steel shell, and causing the outer surface of the steel shell to cling to the inner surface of the rubber outer sleeve; and installing an air nozzle at one end of the air bag, and causing the other end of the air nozzle to extend outside the rubber outer sleeve. The pre-burying device manufactured by the method can be recycled for a long time, so that the labor cost and the cost of funds can be saved, and the environment is protected.
Description
Technical field
The present invention relates to building field, is a kind of gasbag-type concrete hole pre-embedding device and manufacture method thereof 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 all is to do preliminary treatment with pvc pipe or other device, namely use pvc pipe to make pre-buried device, but pvc pipe is difficult to withdraw from afterwards, all is being a kind of waste aspect the energy and the 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 the concrete;
4. because pvc pipe has deformation on length, use pvc pipe to do concrete embedded pore volume and easily cause hole flexural deformation.
Summary of the invention
Technical problem to be solved by this invention provides a kind of gasbag-type concrete hole pre-embedding device and manufacture method addresses the above problem.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: the manufacture method of concrete hole pre-embedding device may further comprise the steps:

Step 2: the inside at described outer steel shell arranges air bag, makes described air bag be close to the inner surface of outer steel shell;
Step 3: at the outer setting rubber sleeve of described outer steel shell, make the external surface of described outer steel shell be close to the inner surface of described rubber sleeve;
Step 4: the end at described air bag is installed valve, and the other end of described valve is stretched out outside the described rubber sleeve end.
Further, described stainless steel is bent to has an end to have more in the two ends that are connected, and the described part that has more consists of joining seam, and the length of described joining seam is the mobilizable length in the described outer steel shell whole body.
Further, round is processed at the position around the corner, two ends of the outer steel shell after the described bending.
The invention has the beneficial effects as follows: air bag drives the size that outer steel shell and rubber sleeve with joining seam expand into required embedded hole size simultaneously in the middle of the process of air pressure bearing, use the produced pre-buried device of this method to recycle for a long time, not only saved cost but also environmental protection.
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, described outer steel shell is the outer steel shell of whole body variable size, 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, and described outer steel shell shrinks.
The invention has the beneficial effects as follows: 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 present invention 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 present invention can be withdrawn from, both operated easy and conveniently, used manpower and material resources sparingly again, and also can not cause building waste, can inject air from the place of valve to described air bag with inflator during use can make the present invention operate, air is taken from the Nature, returns again in the Nature after the use, and the present invention 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 invention; Described outer steel shell is compared more shock resistance anti-vibration with original pvc pipe, and the present invention can recycle for a long time, has not only saved cost but also environmental protection.
On the basis of technique scheme, the present invention can also do 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 then 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 the 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 preferably suppleness with respect to iron plate or other metal.
