Detailed Description
The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. The basic principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents and other technical solutions without departing from the spirit and scope of the invention.
The utility model discloses a pre-buried antiseep PVC drainage casing, below combine the figure, make further description to utility model's structure principle and theory of operation.
The first embodiment is as follows:
as shown in fig. 1 and 2, the embedded anti-leakage PVC drainage casing according to the present application includes a casing body 1, the casing body 1 has an equal diameter from top to bottom, a first connection end 11 and a second connection end 12 are disposed at two ends of the casing body 1, at this time, the first connection end 11 and the second connection end 12 have an equal diameter, a wing ring 2 is disposed between the first connection end 11 and the second connection end 12, and the wing ring 2 is made of metal. Preferably, the wing ring 2 is made of steelThe linear expansion coefficient of the concrete is 8-12 x 10-6V. C, linear expansion coefficient of PVC of 70 x 10-6Per DEG C, the linear expansion coefficient of the steel is 10-12 x 10-6The linear expansion coefficients of concrete and steel are basically consistent, the wing ring 2 made of steel and the concrete expand and contract at different temperatures basically synchronously, and compared with PVC, no gap or tiny gap is generated at the joint of the wing ring 2 made of steel and a floor slab, so that the wing ring 2 of the embodiment cannot or is not easy to leak compared with PVC.
In order to strengthen the connection strength of the wing ring 2 and the casing body 1, preferably, the inner edge of the wing ring 2 is positioned in the casing body 1; preferably, the wall thickness of the joint of the sleeve body 1 and the wing ring 2 is not less than the wall thickness of the sleeve body 1.
Preferably, the inner edge of the wing ring 2 is provided with a positioning piece 3; specifically, the positioning piece 3 is formed by an annular flanging of the inner ring edge of the wing ring 2; further, the positioning member 3 is located inside the casing body 1. Even the increase of this application sleeve pipe along with the live time like this to produce the gap between PVC's sleeve pipe body 1 and the wing ring 2 and appear the seepage, this annular turn-ups can further increase the route of seepage so, and the turn-ups of rising also can increase the degree of difficulty of seepage, further improve this application sleeve pipe's life and antiseep ability. Preferably, the wing ring 2 in the present embodiment is located in the middle of the casing pipe body 1, but may be disposed at any position between the first connection end and the second connection end as needed. In addition, the wing ring 2 and the annular flanging in the embodiment can be integrally formed by stamping; of course, the material can be manufactured and produced by casting, forging, machining and the like according to the requirements of specific materials and processes.
Consider that the convenience is connected the PVC drain pipe about the floor, in this application the inner wall of sleeve pipe body 1 is equipped with annular step 4. Preferably, the annular step 4 is provided with an annular groove 41 towards the side of the second connecting end 12, so that the PVC drain pipe below the floor slab is conveniently connected with the second connecting end 12 of the casing pipe body 1, and the stability of the connection strength is further improved. Preferably, a tapered guide portion 42 is formed on one side of the annular step 4 facing the first connection end 11, so that the PVC drain pipe above the floor slab is conveniently connected with the first connection end 12 of the casing body 1.
Example two:
as shown in fig. 3 and 4, the difference between the second embodiment and the first embodiment is that the sleeve body 1 is stepped, and the first connection end 11 and the second connection end 12 have different diameters. In this embodiment, the inner diameter of the first connection end 11 is larger than the inner diameter of the second connection end 12, the first connection end 11 of the casing body 1 is connected to a floor drain, and the second connection end 12 of the casing body 1 is connected to a PVC drain pipe or the whole casing is directly used as a floor drain. Similar to the wing ring 2 of the first embodiment, the linear expansion coefficient of the concrete is 8-12 x 10-6V. C, linear expansion coefficient of PVC of 70 x 10-6Per DEG C, the linear expansion coefficient of the steel is 10-12 x 10-6The linear expansion coefficients of concrete and steel are basically consistent, when the temperature changes, the wing ring 2 and the concrete stretch synchronously, no gap is generated between the wing ring 2 and the concrete, and water leaks from top to bottom from the gap. Meanwhile, as the inner wall of the casing pipe body 1 is provided with the annular step 4, one side of the annular step 4 facing the second connecting end 12 is provided with the annular groove 41, the PVC drain pipe below the floor is conveniently connected with the second connecting end 12 of the casing pipe body 1, one side of the annular step 4 facing the first connecting end 11 is provided with the conical guide part 42, and the upper side of the floor is conveniently connected with the PVC drain pipeIs connected with the first connecting end 12 of the casing body 1.
It is worth mentioning that the technical features such as the base, the fixed mounting hole that the utility model discloses a patent application relates to should be regarded as prior art, and the concrete structure of these technical features, theory of operation and the control mode that may involve, spatial arrangement mode adopt the conventional selection in this field can, should not be regarded as the invention point of the utility model patent is in, the utility model patent does not do further specifically expand the detailed description.
It will be apparent to those skilled in the art that modifications and variations can be made in the above-described embodiments, or some features of the invention may be substituted or omitted, and any modification, substitution, or improvement made within the spirit and principle of the present invention shall fall within the protection scope of the present invention.
