Lid is individually fixed in the lower end and upper end of the stack shell, is respectively equipped with first through hole and the second through-hole, institute on the cylinder bottom, cover
It states cushion rubber and is wrapped in the stack shell outer wall, the dovetail fixed link passes through first through hole, the second through-hole.
In technical solution, it is preferred that the first reinforcing ring and the second reinforcing ring are respectively equipped on the cylinder bottom, cover, it is described
The inner hole of first reinforcing ring and the second reinforcing ring is corresponding with the first through hole, the second lead to the hole site respectively.
In technical solution, it is preferred that the cylinder bottom, cover are circle, and the first through hole, the second through-hole are respectively arranged on
The cylinder bottom, cover the center point.
In technical solution, it is preferred that first reinforcing ring, the second reinforcing ring are individually fixed in the cylinder bottom, in cover
Surface.
In technical solution, it is preferred that the dovetail fixed link includes sequentially connected dovetail screw terminal from top to bottom, extension
Bar and dovetail screw tail, the dovetail screw terminal is close to the cover side.
In technical solution, it is preferred that the extension shank diameter is identical as the nominal diameter of the dovetail screw tail.
In technical solution, it is preferred that the stack shell shape is cone cell wide at the top and narrow at the bottom.
The utility model has the advantages and positive effects of:
(1) construction of flooring vertical pipe reserved opening is carried out with this pre-embedded device, artificial investment can be reduced, be not required to separately
Arrangement personnel go to remove casing before concrete final set, while avoiding people in morning and damaging to concrete surface perception,
Hole rule and surrounding concrete after construction is closely knit, and reduction avoids concrete from going out the disturbance of floor and hole surrounding concrete
Existing crack and uncompacted situation, reduce the probability of infiltration；
(2) cost is relatively low, and easy to drawing materials, processing and fabricating is simple, easy to use, and capital investment is few, and all pre-embedded devices are whole
It is reusable, it is used in turn number and obviously increases；
(3) the broadening formation hole formed is easy to block, and can reduce hole infiltration probability；
(4) cushion rubber can easily be removed after final set, be not required to smear lubricating fluid in periphery in advance, prevent pollution concrete,
Reduce the probability that seeps water during blocking.

Specific embodiment
Embodiment 1
As shown in Figure 1, the present embodiment provides a kind of flooring vertical pipe reserved opening pre-embedded device, including inner cylinder, cushion rubber 1
With dovetail fixed link, inner cylinder includes stack shell 2, cylinder bottom 3 and cover 4, and the lower end and upper end of stack shell 2, cylinder are fixed in cylinder bottom 3, cover 4
Body 2 be it is wide at the top and narrow at the bottom horn-like, cylinder bottom 3 and cover 4 are circle, and cylinder bottom 3,4 the center point of cover are respectively equipped with through-hole 5 and logical
Hole 6, cushion rubber 1 is wrapped in 2 outer wall of stack shell and shape is matched with 2 outer wall of stack shell, and dovetail fixed link passes through through-hole 5, through-hole 6；Shape
At broadening formation hole be easy to block, can reduce hole infiltration probability.
As shown in Fig. 2, reinforcing ring 7 and reinforcing ring 8 are respectively equipped on cylinder bottom 3, cover 4, reinforcing ring 7,8 internal diameter of reinforcing ring point
Not identical as through-hole 5,6 internal diameter of through-hole, reinforcing ring 7 and reinforcing ring 8 are individually fixed in a bottom 3,4 inner surface of cover, cylinder bottom 3,
