Description
Technical field
The utility model belongs to reserved sleeve construction field of engineering technology, and in particular to a kind of removable sleeve.
Background technique
In engineering construction process, the case where reserved sleeve, is very universal in the concrete structures such as plate class, wall class,
Such as in plant area's drainage system manhole well work progress, the borehole wall is that pipeline reserves aperture, and project amount cannot be ignored.
Traditional construction method is that PVC casing is reserved before the borehole wall concreting of manhole well, complete to concreting
Cheng Hou removes PVC casing reserved before.Why needing the PVC casing that will be reserved removal is because of the presence of PVC casing
Pipeline and borehole wall quality of connection are had some impact on, when blocking processing to gap between pipeline and the borehole wall, PVC smooth contact
It is adversely affected in face of blocking quality.
Traditional sleeve construction mode has the following deficiencies: the 1. reserved bad fixations of casing, and reserved opening is caused to deviate；2.
Reserved set pipe stiffness is unsatisfactory for requiring, and easily causes PVC casing damage in concrete vibrating construction；3. manually cutting PVC casing
Consuming is a large amount of artificial, also results in certain influence to the duration；4. manually picking chisel, arbitrariness is also big, interface appearance quality trait difficulty adds
Greatly；5. the PVC casing after cutting can not utilize again, waste of material is caused, cost control is unfavorable for.
Therefore it provides a kind of removable sleeve, is very necessary.
Utility model content
Utility model aims to solve many problems existing for above-mentioned reserved casing existing in the prior art with
And brought by manually cutting, provide a kind of removable sleeve.
To achieve the above object, the utility model provides following technical scheme:
A kind of removable sleeve, including barrel, barrel connecting plate, barrel are two shapes, the identical arc of size
Barrel, the both ends of each arc barrel are correspondingly connected with the both ends of a barrel connecting plate, form two closed semicircles；Each barrel
Through-hole is provided on connecting plate, fastening bolt is connected and fixed after the through-hole of two barrel connecting plates by matching nut；Two barrels
Rectangular steel bar is mounted between connecting plate.
Further, between two barrel connecting plates, two rectangular steel bars are symmetrically arranged with centered on through-hole.
Further, barrel and barrel connecting plate are to be welded to connect.
For the welding surface of barrel and connecting plate after polishing, section is smooth, suits gapless, rectangular steel bar energy with rectangular steel bar
Play good booster action.
Further, sealing joint strip is added between rectangular steel bar and barrel connecting plate.Concrete can be effectively prevented in this way
The infiltration of cement slurry, while being removed convenient for the later period.
Further, the outer surface of barrel, barrel connecting plate and rectangular steel bar is equipped with corrosion-inhibiting coating or zinc coat.It can keep away
Exempt from the building block during concrete curing to get rusty.
Further, the screw thread in nut and matched fastening bolt is coarse thread.It is easy to use, safely may be used
It leans on.
Compared with prior art, the utility model has the beneficial effects that
A kind of detachable casing provided by the utility model, production method is simple, the cost of material is low, effectively prevents tradition
Lot of materials expense caused by reserved PVC sleeve.The structural strength used in this programme is higher, is unlikely to deform, is displaced, effectively
It is lower to avoid the reserved PVC sleeve strength of tradition, the generation of sleeve disrepair phenomenon is easily caused in concreting process of vibrating,
Ensure construction quality.Meanwhile scheme provided herein is convenient for removing after the completion of concreting, passes through and removes barrel
After the rectangular steel bar of side, two side tube-walls can be removed easily, and greatly reducing traditional PVC sleeve, to remove difficulty big, cause a large amount of
Manually, the case where duration waste situation.Finally, this programme is easy to use simple, and it is easy to disassemble, it can be recycled, effectively avoid
Traditional PVC sleeve can not reuse after cutting, and cause lot of materials to waste, greatly reduce construction cost.
In addition, the utility model Method And Principle is reliable, step is simple, has very extensive application prospect.
It can be seen that the utility model compared with prior art, has substantive features and progress, the beneficial effect implemented
Fruit is also obvious.
