Abstract
A PVC embedded waterproof sleeve comprises a sleeve body which is integrally provided with a waterproof wing ring. A fixing ring is arranged at the bottom end of the sleeve body, a concentric inner tube is integrally connected to the lower portion of the inner wall of the sleeve body, a bearing convex ring is formed by the inner wall of the sleeve body and the outer wall of the inner tube, and a groove is formed in the outer wall of the sleeve below the waterproof wing ring. Two concave-ring-shaped waterproof grooves are formed in the waterproof wing ring, and a plurality of convex threads are arranged on the outer wall of the sleeve body between the groove of the sleeve and the fixing ring. The PVC embedded waterproof sleeve is not prone to water leakage, high in strength, capable of simplifying construction processes, saving in time and labor, convenient to construct, economical, practical, and long in service life, thereby having certain popularization value.
Description
Technical field
The utility model relates to construction water string technical field, relates in particular to a kind of pre-embedded water-proof sleeve tube.
Background technique
In new building constructions engineering construction, all have the place of plumbing requirement toilet, kitchen, washing room and balcony etc., its pipeline generally all wants passing through floors to install, the normally reserved hole that is greater than outer diameter tube 50mm on floor, after pipeline installs, again space holder mould remaining pipeline is filled up with concrete secondary, in order to avoid cause seepage.Due to easily broken easily rust of traditional cast iron sleeve pipe, steel sleeve pipe is made trouble, and expense is too high, easily becomes rusty perishable.These all need to hold in the palm repeatedly filling-up hole of mould above, and destroy concrete integrity, and easy spillage when filling-up hole, is difficult to cleaning, and bottom out-of-flatness again, and time-consuming, work efficiency is extremely low, and very easily cause pipeline to be difficult to the seepage of repairing.
At present, PVC pre-embedded water-proof sleeve tube is also used widely.Existing pre-embedded water-proof sleeve tube, because its structural design is perfect not enough, often there is customer responsiveness pre-embedded water-proof sleeve tube generation water leakage phenomenon, as PVC pre-embedded water-proof sleeve tube and pipe fitting joint because the aging infiltration causing of glue, water leakage phenomenon are a lot, have a strong impact on user's normal life, and very trouble of maintenance.
Model utility content
The purpose of this utility model is in order to solve above-mentioned the deficiencies in the prior art, and PVC pre-embedded water-proof sleeve tube is provided, and it is easy for installation, better anti-leakage property, easy construction.
The technological scheme that the technical problem that the utility model solves adopts is:
A kind of PVC pre-embedded water-proof sleeve tube, comprise sleeve pipe 1, on sleeve pipe 1, be integrally formed with anti-hydrofoil ring 2, the bottom of sleeve pipe 1 is provided with retaining ring 3, the inwall bottom that it is characterized in that sleeve pipe 1 is connected with concentric inner tube 4, the outer wall of the inwall of sleeve pipe 1 and inner tube 4 forms and accepts scrobicular ring 6, and sleeve pipe 1 outer wall under anti-hydrofoil ring 2 is provided with groove 5.When use, before floor concrete casting, the utility model can be located to pipeline place reserved on floor, then by concreting, collar aperture forms pipeline preformed hole, owing to being provided with anti-hydrofoil ring at the outer wall of sleeve pipe, play the effect of isolation, can ensure that Seepage does not appear in the outer wall of sleeve pipe.The method that PVC pre-embedded water-proof sleeve tube of the present utility model is connected with pipe fitting is: the pipe fitting insertion inwall of sleeve pipe and the formation of the outer wall of inner tube are accepted in scrobicular ring, and inner tube stops infiltration and leaks.This structure, without using adhesive, just can ensure that it can not seep water and leak, and very reliable.Sleeve outer wall is provided with groove, has increased and concrete surface of contact, makes pre-embedded water-proof sleeve tube antileaking.
When concrete enforcement, anti-hydrofoil ring 2 is provided with twice hollow toroid capillary groove 21, and sleeve pipe 1 outer wall between groove 5 and the retaining ring 3 of sleeve pipe 1 is provided with some roads dimpled grain 7.Be provided with capillary groove, prevent that the gap between concrete and sleeve pipe from shrinking infiltration, sleeve outer wall is provided with dimpled grain, has increased and concrete surface of contact, further makes pre-embedded water-proof sleeve tube antileaking.
When concrete enforcement, between retaining ring 3 and sleeve pipe 1, be provided with stiffening rib 8, retaining ring 3 is provided with mounting hole 31.Mounting hole, for fixing pre-embedded water-proof sleeve tube of the present utility model, is easily fixed position of the present utility model, ensures the accurate of its pre-buried position.Stiffening rib further improves intensity of the present utility model.
The beneficial effects of the utility model are: the utility model pre-embedded water-proof sleeve tube antileaking, intensity are high, simplify construction sequence, time saving and energy saving, easy construction, and economical and practical, long service life, has certain promotional value.
