Abstract

The utility model relates to a concrete pre-burying anti-leakage special sleeve pipe which mainly solves the problem that no concrete pre-burying sleeve pipe having the advantages of high durability and effective leakage prevention exists at present. One or more than one water stopping wing ring bulged out of a pipe wall is fixedly arranged on the outer wall of the hollow sleeve pipe; the inner diameter of the sleeve pipe is larger than the outer diameter of a pipeline which is matched and sheathed with the sleeve pipe; the gap between the sleeve pipe and the sheathed pipeline can be filled with elastic water-proof sealing materials. A groove of which the inner diameter is larger than the lower part of the sleeve pipe is arranged at the upper part of the sleeve pipe; a length regulating pipe of which the upper part extends out of the groove is sheathed in the groove in a matching way. The sleeve pipe can be made of plastics; because the diameter of the groove is larger than the inner diameter of the sleeve pipe and can be matched with the pipe diameter of a water discharging pipe conforming to the national standard, the sleeve pipe can be freely lengthened as required by inserting the regulating pipe with the definite length into the groove. Because arranged on the outer circumference of the sleeve pipe, the water stopping ring can effectively perform the anti-leakage function. The utility model is mainly used for a preinstalled pipe installation through hole before pipelines are installed in a concrete slab.

Description

Concrete embedded antiseep specialized barrel

Technical field

The utility model relate to a kind of when being specifically designed to the pipeline through-flooring in cast-in-situ concrete pre-buried sleeve pipe.

Background technology

In housing construction, lavatory, kitchen, washroom and other have the house of plumbing, and its pipeline generally all will pass each floor plate and vertically install.When this just requires our disturbing concrete floor, on the position that has pipeline to pass, bury sleeve pipe in advance underground, pipeline is passed from sleeve pipe greater than outer diameter tube.For a long time, the used sleeve pipe in building site generally is to adopt iron pipe or iron plate to make at the scene.Facts have proved that the field fabrication metal sleeve has following shortcoming: 1, manufacturing technology does not pass a test, iron plate is burnt or phenomenon such as weld seam disconnection when often welding occurring.Cause sleeve pipe outer rim seepage; 2, corrosion easily.Because sleeve pipe generally is to be embedded in the concrete of lavatory, kitchen floor, be subjected to the erosion of the very strong liquids and gases of corrosivity all the year round, 1-2 at least, 3-5 at most, sleeve pipe is worn by rust, causes the serious seepage of pore; 3, cost height.The field fabrication ferule is that specification is many, and little in batches, equipment is uneven in addition, and technology is unprofessional, causes cost of production quite high.

Summary of the invention

The purpose of this utility model provides a kind of reliable in quality, cheap, the concrete embedded antiseep specialized barrel that is used for piping erection.

The technical scheme that its technical problem that solves the utility model adopts is: hollow sleeve pipe 1 outer wall is installed with the sealing Ji ring that protrudes tube wall, and the internal diameter of sleeve pipe 1 is greater than the external diameter of the pipeline 8 of the suit that matches with it.

The utility model also can be filled the elastic water-proof encapsulant in the space between sleeve pipe 1 and the suit pipeline 8.The outer wall of sleeve pipe 1 can be installed with the above sealing Ji ring in 1 road or 1 road.Also can establish the tongue and groove 2 of internal diameter greater than the bottom on sleeve pipe 1 top, the length adjustment pipe 9 of tongue and groove 2 stretches out in the engage sleeves portion of loading onto in tongue and groove 2, and the internal diameter of length adjustment pipe 9 is greater than the external diameter of the pipeline 8 of the suit that matches with it.And the elastic water-proof encapsulant is filled in the space between length adjustment pipe 9 and suit pipeline 8.

The beneficial effects of the utility model are: sleeve pipe can adopt the plastics manufacturing, because the diameter of tongue and groove is greater than casing inner diameter and can match with the supplying drainage caliber of national standard, the length adjustment pipe that inserts certain-length in tongue and groove just can make sleeve pipe extend arbitrarily as required.Because of sealing wing ring all is arranged on the sleeve pipe circumferential periphery, it can play the effect that prevents seepage effectively.It mainly is the default piping erection through hole that is used for before the concrete slab pipe laying.It has simple in structure, light, corrosion-resistant, anti-aging, antiseep, durable in use, easy to manufacture, lower-price characteristic.

Among the figure: 1-sleeve pipe, 2-tongue and groove, 3-sealing Ji ring, 4-sealing Ji ring, 5-sealing Ji ring, 6-sealing Ji ring, 7-concrete casting cast layer, 8-pipeline, 9-length adjustment pipe.

The specific embodiment

Embodiment 1, and hollow bushing 1 outer wall of the present utility model is installed with the sealing Ji ring that protrudes tube wall, and the outer wall that described sealing Ji ring both can be located at sleeve pipe 1 sets firmly 1 road or 2 to 6 roads or more than 6 roads, as shown in figures 1 and 3 for 4 roads are set.The internal diameter of sleeve pipe 1 is greater than the external diameter of the pipeline 8 of the suit that matches with it, so that pipe laying 8.For the enhanced leaktightness effect, can fill the elastic water-proof encapsulant in the space between sleeve pipe 1 and the suit pipeline 8.In use according to its design feature, earlier according to the selected suitable sleeve pipe 1 of diameter of designing requirement, then sleeve pipe 1 is installed on the template of assigned address, and fixed sleeving 1, disturbing concrete 7, make

sealing wing ring

3,4,5,6 respectively with the tight interlock of concrete seven, because the obstruct of 4 road sealing wing rings, ponding on the flooring can't be oozed out in the concrete of sleeve outer wall, thereby can effectively guarantee no seepage and no leakage, after sleeve pipe 1 was fixed in the concrete, pipeline 8 just can pass from sleeve pipe 1, and the elastic water-proofing material sealing is filled in the space between pipeline 8 and sleeve pipe 1.

Embodiment 2, establish the tongue and groove 2 of internal diameter greater than the bottom on sleeve pipe 1 top, and the length adjustment pipe 9 of tongue and groove 2 stretches out in the engage sleeves portion of loading onto in tongue and groove 2, and the internal diameter of length adjustment pipe 9 is greater than the external diameter of the pipeline 8 of the suit that matches with it.Yet can fill the elastic water-proof encapsulant in the space between length adjustment pipe 9 and the suit pipeline 8.It can when sleeve pipe 1 needs lengthening, can make it to connect firmly with sleeve pipe 1 according to instructions for use with inserting in the tongue and groove 2 behind length adjustment pipe 9 gluings of certain-length, makes the total length of sleeve pipe 1 meet instructions for use.The utility model can adopt plastics to make, thereby overcome many shortcomings of metal straight connector, has filled up the blank that piping erection does not have special-purpose pipe box, has reached that technology is reliable, specification standardization, saving steel, the purpose that is widely used, significantly reduces cost.And it has simple in structure, light, corrosion-resistant, anti-aging, antiseep, characteristics such as durable in use, easy to manufacture.Consult Fig. 1 to Fig. 4.Consult Fig. 1 to Fig. 3.
