Method of making a pipe passage and pipe passage

Background of the Invention

The present invention relates to a method for making pipe passage according to the preamble of claim 1. The invention further relates to a pipe passage according to the preamble of claim 2. In particular, the invention relates to a method of making a pipe passage and a pipe passage used to connect, for example, waterproofing in floor or wall structures of washrooms and other wet rooms in a building to sewer or water pipes routed through the floor or wall.

It is an object of the present invention to provide a method and a tubular transfer whereby water-insulating masses and substances as well as waterproofing mats, which are applied in a fluidized form to waterproof the substrate of ceramic surfaces in wet and damp conditions, can be waterproofed and reliably attached

15 In built-up areas where water is used, it is generally a requirement that wall and floor surfaces must have a waterproof structure which prevents moisture from entering the structures. This waterproofing layer shall also be uniform and tight against any floor or wall pipe or other penetrations. Providing a watertight connection, for example, for pipes routed through the floor and wall structures, has proved to be a problematic and laborious task with the potential for structural defects::: large.

φ · · i ": Particularly in the construction method where pipe penetrations are installed at the top edge to facilitate leveling of the surface structures with the floor or wall surface, there is no fully reliable method for obtaining a waterproofing. ···! different stages of work are often carried out by different people and because of this, there are many construction methods available than, perhaps, many suppliers whose working methods or • · · **]; * products are not optimally suited for use with each other. 30 easy installation errors that make it difficult to achieve a reliable and tight joint *: ··: field.

Requirements for the joint are also pre- • * * · "35 characters in the type approval of floor drains.

These requirements include the tightness, i.e. the retention of the mat ring, in the well, including 2,119,828 after the aforementioned aging. The disadvantage of most joints today is that their water tightness between penetration and waterproofing is not sufficiently reliable and durable given the long lifetime required for the joint.

5 In practice, there are two main methods well established in the market for making a waterproofing joint. In one way, waterproofing is applied directly to the inner surface of the penetration mounted directly on the structure. In this case, the sealing of the joint is based on the fact that the mass adheres tightly to the inner surface of the lead-through. However, since the penetrations used today are usually made of plastic materials which are not reliably adhered to the waterproofing compounds but are released over time, the water and moisture in the penetration often penetrate into the floor structures below the waterproofing compound.

Another well-established method of joining uses 15 specially designed joining members comprising a sheet-like piece of carpet or gauze of about 40 cm by 40 cm. In most cases, the edge of this joint has a perforation or gauze to secure the sealing compound. The fitting member is inserted into the lead-through by means of a special locking ring which is pressed against the lead-in member towards the lead-through, forcing the connector 20 to bend inside the lead-through, being trapped between the locking ring and the inner wall of the lead-through. However, the carpet pieces used as a joint are generally thinner than the surface carpets, so the joint will not become a tight but penetration: .. v and there may be a gap between the carpet and the water and moisture to penetrate the floor-

The waterproofing compound should allow 3 119828 to dry before installing the carpet ring, but generally the installation is done in one go, i.e. the waterproofing is still in fluid form when the locking ring connecting the gauze fabric through is pressed into the throughput. In this case, the waterproofing material will flow out under the locking ring and the resulting joint will in practice be based solely on the gauze fabric and may not be tight. Therefore, the use of such a gauze bandage requires a great deal of skill to succeed, and to remain tight.

Brief Description of the Invention

It is an object of the present invention to address the problems associated with the prior art ankle and to provide a new structural solution that best secures the requirements for waterproofing.

This object is achieved by the fact that the present method of making a pipe passage and a pipe passage according to the present invention have the features defined in the claims. More specifically, the method according to the invention is essentially characterized by what is stated in the characterizing part of claim 1.

The pipe passage according to the invention, in turn, is essentially characterized by what is stated in the characterizing part of claim 2.

Advantageous embodiments of the method of making a pipe passage according to the invention and the pipe passage 20 are the subject of the dependent claims.

Thus, the waterproofing installation step: can be completed in one step, ie the pipe passages are tight immediately after the work:. **: 35. The waterproofing can also be fitted tightly to the pipe penetration, even though the penetration would be cut off to the concrete surface.

Since the method of making the pipe penetration according to the invention involves fewer work steps than before, installation work is also faster and many installation errors can be avoided.

By using a pipe bushing installation sleeve 5 which is substantially the same size as the sewer pipe, the installation bushings can be assembled with one another and thus, if necessary, extend the sewer pipes or change the damming height of the pipe bushing.

BRIEF DESCRIPTION OF THE DRAWINGS

The invention will now be illustrated by reference to a preferred embodiment of the accompanying drawings 10, in which: Fig. 1 is an and Fig. 3 is a cross-sectional view of one embodiment of the mounting sleeves to be fitted together.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present method for making pipe passage and pipe passage. . *. Some preferred embodiments of exportation are described below with reference to the above. said figures. In this case, the pipe gland comprises the components designated by reference numerals in the figures, which correspond to the reference numerals used in this specification. . numerals.

The present method for making a pipe passage relates to a solution in which the pipe passage is combined with waterproofing to the surface of the structural layer by known working methods. Such a waterproofing material may be a conventional plastic mat, but will be described in particular below as a solution to sealing the seam between the waterproofing material 30 1 to be applied in a fluid form and the lead-through 3 in the solid structure 2. However, the solution shown is equally applicable to the use of the aforementioned plastic mat. * with.

Thus, in the embodiment shown in Fig. 1, there is shown a solution in which the solid structure 2 has a through-hole 3 extending from its upper surface 4 to the structure-35 119828 in a manner known per se to provide a seal. and a part of elastic material having a cylindrical part 6 parallel to the upper surface and having an adhesive region for the waterproofing material. Such a gripping area comprises, for example, holes at its outer edge and recesses at its inner edge to improve grip. Preferably, the cylindrical portion is circular, but may alternatively have other shapes, such as polygonal. The cylinder member is still attached to a waterproofing compound 1 applied to the upper surface of a wet solid structure, whereby adhesion to the waterproofing compound mass can be ensured by applying it to both sides of the cylinder member.

10 There is a hole in the middle of the connecting part 5 or a hole can be provided in the installation step, which allows the connecting part to be guided into the lead-through 3 to form the collar part 7. Alternatively, the coupling member comprises a collar portion extending therefrom substantially dimensioned to the inner diameter of the lead-through. This collar member is guided into the lead-through and is mechanically connected to the inner wall 8 thereof, preferably by means of a press connection.

The collar portion 7 in the connection portion 5 extending into the lead-through 3 is arranged to press against the inner surface 8 of the lead-in wall by preferably fitting a double-cylindrical mounting sleeve 9 into the lead-through. The mounting sleeve is preferably made of substantially rigid material. Such a mounting sleeve then has a lower cylindrical sleeve 10 having an outer diameter smaller than the inner diameter of the lead-through and an upper cylindrical sleeve 11 having an outer diameter larger than the inner diameter of the lead-through. Thus, as shown in Fig. 1, the mounting sleeve is adapted to rest against the upper edge of the passage through the conical or flange surface formed by the interface between the lower and the upper cylindrical sleeve. The present upper cylindrical sleeve 11 has a dimension from the surface of the waterproofing opposite to the mounting sleeve. 3. When the penetration is on the floor surface, a water insulator can thus be lifted into the upper cylindrical sleeve to form a so-called dam height in the room surrounding the via.

*;]; * 30 When guiding the lower sleeve 10 of the mounting sleeve to the lead-through, * ··· * causes the outer surface of the sleeve to be pressed into the collar 7. When ·: ··! at least one sealing member according to Fig. 1, such as a sealing flange 12, or, in the mounting sleeve, at least one sealing member according to Fig. 2, such as a sealing flange 13, • · · | 35 a tight joint between the joint and the via is desired.

* · * · Sealing rings of different shapes can also be used for the sealing member.

The present solution can be manufactured in one continuous operation step, without the need for drying of the waterproofing material applied to the upper surface of the solid structure. Since the tightness between the coupling part and the lead-through is based on both mechanical compression and utilization of the sealing flanges ai-5 provides a joint which also has the necessary long-term durability.

Thus, the present tubular gland comprises a grommet 3 in a solid structure 2 to which is connected a connecting portion comprising a plate-like cylindrical portion 6 and a collar portion 7 with the collar portion inserted into the gland in the immediate vicinity of its wall surface 8. Further, such a put-10 shield bore has means for fitting the collar portion to the lead-through. These means consist of a double cylindrical mounting sleeve having a lower cylindrical sleeve and an upper cylindrical sleeve. The final tightness of the pipe entry is secured by fitting at least one of the sealing members 12 or 13 between the mounting sleeve and the lead-through, as shown in Figure 1 or 2.

Preferably, the sealing member 12 is arranged to have a flange-like structure fitted to the inner surface 8 of the collar portion 7, as shown in Figure 1. Alternatively, the sealing member 13 is arranged to comprise a flange-like structure disposed on the outer surface of the lower cylindrical sleeve 10 in the mounting sleeve, as shown in Figure 2. Preferably, such a sealing flange is elongated so as to have a dimension substantially in the direction of the cross-sectional plane of the lead-through. This allows for some degree of compliance with the • • installation tolerances during installation as well as the ready-to-assemble tolerances of the components.

: ***: By arranging the inside diameter of the upper cylindrical sleeve 11 in the mounting sleeve 9, the internal diameter of the receiving bushing 3 is substantially equal to the internal diameter of the receiving bushing 3: * ·. ···. assembling the sleeves together. This allows, for example, • an easy extension of the drain pipe formed by the through-hole and an increase in the dam height of the pipe-through.

Of course, it should be noted in this connection that the mounting sleeve 9 in the pipe passageways · · · · ♦ · * can be fitted in accordance with Figs. 1 or 2 *: **: in a manner known per se, e.g. connecting the drain 15 to the pipe passage.

. When the top of the mounting sleeve is not high enough above the finished floor clamp; With 35 such pins, the damming height of the pipe penetration • · 9 • ·· • · 7 119828 can be secured. Thus, the lead-through joint is pressed against the inner surface of the upper cylindrical sleeve of the mounting sleeve with such force that this joint is completely sealed.

It is to be understood that the foregoing description and the accompanying drawings are only intended to illustrate the present method for making tubular through-5 and tubing through. Thus, the method and the tubular entry are not limited to the embodiment described above or as defined in the claims, but many variations and modifications of the invention which are possible within the scope of the inventive concept defined in the appended claims will be apparent to those skilled in the art.
