Description
Technical field
The utility model relates to a kind of sleeve pipe that floor is reserved the hole that is used for.
Background technology
In construction work is installed, need in concrete floor, reserve the hole usually, to be used for burying machine electric line etc.In general, the floor hole to be provided is after the installation of slab form, marks the hole to be provided position at template upper drawing circle circle, nail is set around the circle then, with casing clamp within the nail circle.For the stability of reinforcing sleeve with prevent that the bottom of concrete from sleeve pipe from getting in the sleeve pipe, it is suitable for reading and be bundled on the nail to pass sleeve pipe with iron wire, but also must adopt certain sealing measure to sleeve pipe top, prevent that concrete from getting into from sleeve pipe top.
Above-mentioned usual manner has numerous drawbacks.For example, when removing sleeve pipe, need cut off iron wire.Because iron wire is cast in inside concrete, the inner surface at as easy as rolling off a log destruction hole causes concrete defect when therefore cutting off iron wire and removing sleeve pipe.In addition, build in the process concrete, the inside of sleeve pipe also gets into concrete easily.In addition, workman's operational sequence is many, and construction efficiency is low.
The utility model content
To of the prior art above not enough, the utility model aims to provide a kind of sleeve pipe that floor is reserved the hole that is used for, and it is simple in structure, and is easy to manufacture, easy to use.
According to the utility model, a kind of sleeve pipe that floor is reserved the hole that is used for is provided, comprise body, be installed in the fixed head at the first end place of body, and the blind plate and the handle that are installed in the second end place of body.This sleeve pipe also comprises the revolving part that is arranged on the body center with vertically passing body, and it comprises axis of rotation, and be separately positioned on axis of rotation two ends places swivel head and from tap holder.
In one embodiment, swivel head is located at the end near the second end of body of axis of rotation, and protruding the first end from body from tap holder.
In one embodiment, blind plate has sealed the second end of body.Preferably, handle is welded on the blind plate.
In one embodiment, also be provided with locating part on the part in the body, be used for preventing that axis of rotation from skidding off from body being in of axis of rotation.
In one embodiment, fixed head is the stripe board that is connected on the inboard wall of tube body, and the width of this stripe board is less than the internal diameter of body.
According to the utility model,, just can sleeve pipe be securely fixed on the template through rotating swivel head through aiming at from tap holder of sleeve pipe is opened in the prebored hole (its center roughly overlaps with the center at required reservation hole) on the slab form.When removing sleeve pipe, only need oppositely rotate swivel head, be aided with again and strike shake and/or rotate handle, can drawing go out sleeve pipe, obtain the bright and clean reservation hole of inwall.
Through being arranged on blind plate and the fixed head on the sleeve pipe, make sleeve pipe to bear and knock, and its roundness being able to guarantee.In addition, blind plate can avoid concrete when building, to enter in the body.
Sleeve structure according to the utility model is simple, can repeat repeatedly to use, and cost is lower.Simultaneously, can guarantee that concrete does not get into inside pipe casing.In addition, whole pre-buried process is easy to dismounting simply, accurately, easily and fast, is difficult for falling, does not become flexible, does not advance ash, can simplify construction technology more greatly.During dismounting, can guarantee concrete finished product protection.
Description of drawings
Come the utility model is done further explain below in conjunction with accompanying drawing, wherein:
Fig. 1 is the sectional view according to the sleeve pipe of the utility model.
Fig. 2 is the sectional view along Fig. 1 center line 1-1.
The specific embodiment
Fig. 1 has shown the sleeve pipe 10 according to the utility model.As shown in the figure, sleeve pipe 10 comprises body 1 and the handle 2 that is installed in an end (upper end among the figure) of body 1.Handle 2 for example can be conventional U-shaped handle.Body 1 for example can be steel pipe or coating steel pipe, its outside dimension and hole to be provided hole measure-alike.
The end that handle 2 is installed at body 1 is provided with blind plate 5, and it for example is and the equal-sized circular slab of the external diameter of body to be used for this end of closed tube 1.In one embodiment, handle 2 can for example be fixed on the blind plate 5 through welding.The other end at body 1 is provided with fixed head 7.In a specific embodiment shown in Figure 2, fixed head 7 is a bar steel plate, and its width (for example being 4cm) less than the internal diameter of body 1, be fixed on the inner surface of body by two ends.
According to the utility model, sleeve pipe 10 also comprises the revolving part that vertically passes body 1 and be arranged on body 1 center, it comprise axis of rotation 6 and be separately positioned on axis of rotation 6 two ends places swivel head 3 and from tap holder 4.Swivel head 3 is located at the end near handle 2 of axis of rotation 6, and protruding in the end (lower end the figure) opposite with handle 2 from body 1 from tap holder 4.In a specific embodiment, for example be that φ 12 is from tap holder from tap holder 4.Understand easily, can pass body 1, on blind plate 5 and fixed head 7, be equipped with the through hole of suitable size in order to make revolving part.
In use, at first utilize instrument such as Electric portable drill to get out a hole at the desired location place of slab form, the central axis in this hole should roughly overlap with the central axis at required reservation hole.Then, with sleeve pipe 10 expose aim at the above-mentioned hole that gets out from tap holder 4.Through rotate above-mentioned swivel head 3 with hand, just can utilize from the self tapping effect of tap holder 4 and sleeve pipe 10 is securely fixed on the template.In one embodiment, the diameter of boring for example may be selected to be about 6mm.
When after accomplishing concrete cast, removing sleeve pipe, only need oppositely rotate swivel head 3, be aided with the handle 2 that strikes shake and/or revoling tube 10 again, can drawing go out sleeve pipe.Stop 10 pairs of concrete destructions of sleeve pipe thus, obtained the bright and clean reservation hole of inwall.
Because the upper end of sleeve pipe 10 is provided with blind plate 5 and the lower end is provided with fixed head 7, therefore strengthened the bulk strength of sleeve pipe 10, make sleeve pipe to bear and knock that its roundness is able to guarantee simultaneously.In addition, the blind plate 5 that has sealed the body upper end is set, can avoids concrete when cast, to enter in the body 1 through upper end at sleeve pipe 10.
As shown in Figure 1, in a preferred embodiment, locating part 8 can be set on axis of rotation 6.This locating part 8 is arranged on being in the part in the body 1, through preventing that with engaging of blind plate 5 axis of rotation 6 from skidding off from body 1 on the axis of rotation 6.In a specific embodiment, locating part 8 is the circular rod member of φ 12.
The above is merely the preferred implementation of the utility model, but the utility model protection domain is not limited thereto.Any those skilled in the art all can carry out suitable change or variation to it in the disclosed technical scope of the utility model, and this change or variation all should be encompassed within the protection domain of the utility model.
