Description
Technical field
The utility model relates to a kind of water power to reserve tube-in-tube structure, and in particular to a kind of cast-in-place concrete floor water power is pre-
Stay sleeve.
Background technique
It is hydroelectric line reserving hole that cast-in-place concrete floor, which applies man-hour requirement,.The prior art be all allow building site carpenter according to
It needs to make, installation profiled template, it is then directly pre-buried in cast-in-place concrete.It is cumbersome, and profiled template used is not
It can reuse, low efficiency, operation are slow, at high cost, while not fixing well between the bottom of casing and formwork face
Measure, directly placing causes casing to be easy to happen disturbance in concreting process, causes sleeve position inaccurate.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of water power for cast-in-place concrete floor to reserve sleeve,
It can not only precise positioning, moreover it is possible to recycling is reused,
In order to solve the above-mentioned technical problem, the utility model provides a kind of reserved set of cast-in-place concrete floor water power
Cylinder, including standing screw, covers in the sleeve on the standing screw and the limit spiral shell between the standing screw and sleeve
Mother, one end of the standing screw are fixed on the design position of the template of floor, and the sleeve is open tubular column closed at one end,
Facilitate installation and save material, the closed end center of the sleeve is equipped with the through-hole passed through for the standing screw, the sleeve
Fixing end of the closed end far from the standing screw, i.e. sleeve tips upside down on slab form, and the stop nut is set in institute
The free end of standing screw is stated, limitation sleeve is moved axially along standing screw, the closed end of the stop nut and the sleeve
It abuts and compresses, further limit sleeve in the displacement of standing screw radial direction, stablize the position of sleeve, when sleeve portion is not smart enough
When true, stop nut can be unscrewed, sleeve portion is adjusted, then screws stop nut, make stop nut clamp sleeve, fixes sleeve
Position, when concrete floor slab placement is completed, sleeve can be recycled by screwing off stop nut.
Further, the fixing end of the stop nut is fixed with pedestal, and the pedestal passes through the mould of fixing piece and floor
Plate is fixed, and pedestal is slab construction, is further ensured that the stabilization of standing screw position, will not be shaken.
Further, the fixing piece is iron nail, and iron nail at least wedges two of pedestal diagonally, and easy for installation, structure is steady
Gu.
Further, the closed end of the sleeve is equipped with handle, convenient to extract sleeve out after the completion of concrete floor slab placement.
Further, the through-hole diameter is less than the stop nut outer diameter, facilitates stop nut to abut and compresses described
Sleeve closed end, limitation sleeve are axially and radially moved along standing screw, and one end of the stop nut is additionally provided with convenient for described
The protrusion of stop nut installation.
A kind of cast-in-place concrete floor of the utility model reserves sleeve with water power, beneficial effect compared with prior art
It is that will form stable structure between sleeve and slab form, reinforces sleeve in reinforcing bar binding and concreting process
Stability, installing and dismounting is efficient and convenient, can repeatedly recycle and reuse, and effectively accelerates construction progress, and shortens overall apply
The work duration.
Detailed description of the invention
Fig. 1 is the utility model embodiment explosive view；
Fig. 2 is the utility model embodiment cross-sectional view.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art
The utility model may be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.
As shown in Figure 1, being regarded for a kind of cast-in-place concrete floor of the utility model embodiment with the explosion that water power reserves sleeve 2
Figure, including standing screw 1, covers in the sleeve 2 on the standing screw 1 and the limit between the standing screw 1 and sleeve 2
Position nut 3, one end of the standing screw 1 are fixed in the template of floor, and the position of standing screw 1 is required installation in design
2 position of sleeve center, the sleeve 2 be open tubular column closed at one end, 2 sets of sleeve on standing screw 1, the sleeve 2
Closed end center be equipped with the through-hole 4 passed through for the standing screw 1, the closed end of the sleeve 2 is far from the standing screw 1
Fixing end, passed through for convenience of standing screw 1, the diameter of standing screw 1 is less than the diameter of through-hole 4, to prevent sleeve 2 along fixation
Screw rod 1 moves axially, and the stop nut 3 is set in the free end of the standing screw 1, since 1 diameter of standing screw is less than
4 diameter of through-hole, for the displacement of further limitation sleeve 2, the stop nut 3 abuts the closed end for compressing the sleeve 2, sleeve
2 are equally limited along the displacement of screw rod radial direction, it is ensured that sleeve 2 reinforcing bar bind and concreting process in stability, if
The position of sleeve 2 is inaccurate, can unscrew stop nut 3, again screws stop nut 3 after adjusting the position of sleeve 2, floor pours
After the completion of building, the reuse of sleeve 2 can be recycled by screwing off stop nut 3.
As shown in Fig. 2, being the utility model embodiment cross-sectional view, to guarantee fixed firm, the fixation of standing screw 1
The fixing end of screw rod 1 is fixed with pedestal 5, and the pedestal 5 is fixed by the template of fixing piece and floor, further, described solid
Determining part is iron nail, for convenience of installing, it is only necessary to diagonally wedged at two of pedestal 5 iron nails can firm banking 5 and standing screw 1,
For convenience of sleeve 2 is recycled after the completion of concrete floor slab placement, the closed end of the sleeve 2 is equipped with handle 6, will be covered by lift-pull handle 6
Cylinder 2 is pulled out from the floor for pour completion, as preferably, 4 diameter of through-hole is less than the stop nut 3 in the present embodiment
Outer diameter facilitates stop nut 3 to abut and compresses the sleeve 2, and one end of the stop nut 3 is additionally provided with convenient for the stop nut
The protrusion 7 of 3 installations, facilitates and tightens nut by hand.
When utility model works, standing screw is installed on the design position of slab form first, secondly by sleeve
It covers on standing screw, finally sleeve is limited with stop nut, stable knot will be formed between sleeve and slab form
Structure, reinforce sleeve reinforcing bar bind and concreting process in stability, while can also shorten water power casing installation when
Between, installing and dismounting is efficient and convenient, can repeatedly recycle and reuse, and reduces artificial and cost input, effectively reinforces accelerating construction
Progress shortens the overall construction period.
Embodiment described above is only preferred embodiments for fully illustrating the utility model, the utility model
Protection scope it is without being limited thereto.Those skilled in the art made equivalent substitute or change on the basis of the utility model
It changes, both is within the protection scope of the present invention.The protection scope of the utility model is subject to claims.
