EP3260625B1 - Sealing around water supply installations trough components of a building structure - Google Patents

Description

Through the invention, pipe penetrations of water installations are covered by surfaces of space-forming components behind the cladding sealed against ingress of water from the room, at the same time inevitably penetrated water without damage and derived without deposits to the outside.

Pipes of a utility or drinking water bearing installation can be space-saving components, such as walls, ceilings and floors of utility or living space to save space, easily and safely protected against temperature differences that act on them, and noise emissions that emanate from them, without the optical Disturbing the room image (eg in the case of cladding of their component surfaces which is elaborately designed by tiles etc.). Where appropriate, they are also laminated by pre-wall constructions or installation walls that perform the same function but allow more space for the installations. From the installations, especially in wet rooms such as toilets, bathrooms and kitchens water z. B. in bathtubs, hand basin, toilet cistern can be tapped, for which they end up from the component through openings through their clothed or unclothed surfaces with a shut-off valve in the room, as well as with other fittings such. B. Pipe aerators, pressure reducers, which serve the operation of the installations for the intended use.

It can not be avoided in general that even with careful handling in normal use, small amounts of water from the valve or from other fittings will run back to the component surface through spraying or distraction, or water draining from it through the breakthrough for the pipe installation will penetrate to and into the component substance. In addition, for wet rooms from the outset, a high water stress of the component surfaces is expected. A tile surface z. B. is already due to the (water) permeability of their joints no sealing function assigned. It only lets water flow off the faster, the smoother, pore-free the surfaces are, whereby a coarse, but not every moisture penetration can be avoided to the required extent. Therefore, according to the commonly accepted rules, which are based on many years of experience, the component surfaces are, depending on the level of their stress, certified, water-repellent or more or less water-blocking materials in coatings, in the dense gluing or sealing medium, certified in approvals and test certificates of neutral institutions. Mortar composite oa seal. On the other hand, however, the sealing also hampers drying out of the substance of water which has invariably penetrated the installation openings of the clothed or unclothed surface described above.

To preserve nonetheless optically pleasing surface designs of the (wet) rooms, the flat component seals are arranged behind the structural component cladding on condition that the claddings themselves are able to cope with the stresses caused by water, ie they must be moistened without damage to the sealing level. In the places where the pipe installation pierces the clothing, the component substance is therefore not protected, because even the surface seal is broken right there, or will be got to. Water from the interior of the room finally wets the breakdown of the substance of the components behind it, even if only to a limited extent, but repeatedly damaging, because the component clothing (eg a tiling) which is relatively dense to protect the component substance against undesirable stress hindered enough rapid and complete dehydration. The moisture accumulated in the component covers the substance far more effectively, damages it, ultimately impairs its load-bearing capacity and allows mold fungi to settle due to a tendentially damp substrate (at least from tile joints).

The actual cause of this can hardly be the unavoidable room side, especially as intended and therefore permissible penetrating water, but a not sufficiently adequate sealing of the penetration point of the installation through the surface of the component or clothing, which has grown meaningful and effective the stress. The design of a seal alone is not enough; At the same time, a solution has to be created to allow jammed water to flow out of an effective seal as quickly and completely as possible.

Although it is known that very often a closure is attempted for the purpose of sealing with permanently elastic material directly on the surface around the breakthrough, but on the one hand not good as a common recognized sealing detail, on the other hand, in practice, in particular long term does not remain effective, ruptures, rigid or porous so that ultimately water permeates.

Also known are the tube blocking or sufficiently diffusion-tight, elastic cuffs that abut the flat sealing plane and although to lock against water at the immediate pipe penetration or prevent it from moisturizing the substance behind, but spreads beyond the edges of the cuff and thus must remain in the substance. They are not able to let water that had penetrated from the substance flow out again until then; apart from the fact that they are difficult to incorporate effectively tight in the surface component seal, because the different types of sealing materials and materials can not connect safely and long term. This is already derived from the relative to the cuff less elastic, flat seal, similar to edges of waterproofing membranes and films that must be kept in order to protect effectively.

In this sense, the European patent (application number 87103556.4 dated 11.03.1987, publication number 0 240 764 A1 ) a slipped over the installation tube sealing element in the form of an elastic flap of sealing plastic on a porous fabric, with which the sealing element is embedded and anchored, for example, in the adhesive tile laying. However, it only seals so that water remains damaging in the floor or wall construction and is not collected and directed outwards through openings, thus merely improving the sealing plane around the penetration.

With the European patent (application number 07115374.6 from 31.08.2007, publication number EP 1 908 887 A1 ) will the Drainage of a floor surface via a slit and a collecting trough underneath for drainage in a drainage structure in the ground in the sense of a gully pursued, so the opposite of a drainage improperly in the construction of a component penetrated water to keep it dry.

After the US-American patent (application number 14 / 794.192 from 08.07.2015, publication number US 2016/0010341 A1 ) tiles are added without mortar via a two-piece ribbed pattern to a supporting base, whereby this system aims at any production of clothing of a space-forming component surface, but not a seal and drainage of water, they may not allow at all, certainly not to a penetration.

Not known, however, are solutions that complement the perforated, surface sealing and prevent further tiling from the room penetrating water in the pore volume of the building fabric and can flow out immediately to the breakthrough or dry out.

These objects are achieved by the invention according to the appended claims.

The object is achieved by a construction according to claim 1, wherein a thin (eg., Stainless steel) metal or plastic plate (as required with a thickness in or below the millimeter range) with at least lower, more effective also with bilateral, lateral or solved with circumferential, narrow Randabkantung by accurately pierced to the cross section of the water-bearing installation tube, according to position and by caliber (size) on a single element of any arbitrary to choose surface design clothing mirror (eg for a tile picture) is tuned to them can be adapted both to the local requirements from the circumstances of the position and size of the pipe as well as the position and size of the element of the clothing in the plane of the surface sealing of the component (the center of the pipe cross-section need not be located symmetrically with respect to the element, since both are usually independent of each other remain, as far as they are not coordi- nated with one another by coordi- nator measures, which can be and will be fulfilled when executed without great tolerances).

Since the plate should not wear, but seal, it must not be rigid, but may also be more or less flexible or malleable, making it easy to adapt to local conditions.

It is for sealing by a compatible with plate and pipe material adhesive strips (eg a liquid plastic seal), the purpose hardly costly complicated by welding or by one or two-sided pressed or glued, with additional preparations also screwed flanges oa tight with the Pipe (generally after or at the installation sheet) connected and can accommodate the clothing element due to their previously aligned size and location. The firm connection of the plate to the pipe ensures that it moves with the pipe or its small movements of flow and temperature stresses, so regardless of a (usually rigid) sealing of the component remains, thus it can not tear off. The substance thus remains permanently dry.

The plate may therefore (outside or immediately before the surface seal) with their on the different clothing structure of a predetermined according to planning element mirror or a freely selected element image z. B. for a glued or mortared tiling, of wood or plastic elements u. a. adapted narrow edge edgings to the outside, d. H. towards the room so that they may comprise the garment element (eg a tile) like a frame for a revision flap and hold it either by gluing or by magnets, bendable clips or just the (rigid or permanently elastic) circumferential jointing.

The diameter of the bore of the plate is thus adapted to that of the water-bearing pipe, its position in the plate on the element of the surface clothing, the plate size of the on the male clothing element. The hole must therefore not in the middle, but may arbitrarily, if necessary, also be arranged outwardly in the plate, so advantageously compensated for compensation of tolerances locally when the component, before final assembly of the installation (nozzle) according to clothing mirror and (such with a tile to be matched). If the pipe feed-through is arranged in the surface of a clothing element, the plate size depends solely on the element; if it is arranged in or near a joint crossing, the adjacent elements determine the plate size that is to be covered.

The effort required for this work preparation corresponds to the conventional planning and the same the installation of the installation and the laying of clothing. He moves only temporally to a leading point.

If the joints of the clothing are very narrow and require the edge edging of the panel more space, the garment element held by it (eg tile) on it (namely on the surface between the edge Aufkantungen) can be tailored to craft practice deviating slightly from the coordination measure so that it does not disturb the joint pattern.

This has the additional advantage that the installation remains accessible behind the plate as with a revision flap.

On the outer surface of the pipe running back or from the room anspritzendes or running on the clothing of the component water can penetrate where the clothing and the flat seal from the pipe is broken, possibly up to the behind inserted into the sealing plate, there is collected and seeps down by gravity in the narrow gap between her and the held clothing element down where it is caught at the lower edge of the edge, prevented from spreading on the side or outwards or penetrates through the diffusion-open joint to the outside. For this purpose, the grouting of the lower edge can be made open-pored or permeable as needed, or omitted altogether. Penetrated water is thus kept away from the building substance behind the planar seal despite the gap created by the breakthrough or it offers him no large pore volume more for massive penetration and it is derived on a short way back to the outside, without having to flow through a hydraulically bonded clothing structure to be able to solve components that are deposited again on evaporation of the garment surface after evaporation become.

The element of the component garment can be broken cleanly and precisely fitting the tube and, without a rosette on the surface, be visually attractively closed permanently elastic (without this having to combine the compulsory function of a seal). A standard rosette can nevertheless be set up.

FIG. 1 allows a section of a top view of the with a by (a joint formation according to planned element mirror between) elements 5 (in this case, for example, tiles) optically shaping clothing 4 a surface 2 of a space-forming component 1 recognize. The up to just below the space facing surface of the held element 5 (in the example selected form of a single tile) the clothing 4 projecting lower Randabkantung 10 with its above open joint (alternatively their diffusion-open joint closure) 12 relative to the held element 5 and rigid with the below Joint closure 14 to adjacent elements 5 and on both sides and top peripheral Randabkantungen 11 with their inside the held element 5 permanently elastic sealed joints 13, with their outside rigid joints closures 14 to adjacent elements 5 are circumferentially on their track (in the drawing plane) order an element 5 can be seen, which is held behind it by the position and size thereof and the (for example eccentric) position and size of a continuous through the opening 7 installation tube 8 plate 9. An optionally only optically, not sealingly covering rosette 19 is not shown.

FIG. 2 leaves in a cross section perpendicular to the plane parallel to the joint on the longer side of the covering element 5 approximately centrally through the tube 8 of FIG FIG. 1 illustrated plan view of the structure behind the 4 forming the surface 2 of the space-forming component 1 and its immediately applied surface seal 3 recognize that was disturbed or broken at the point of the opening 7 for the installation tube 8 through the clothing 4 and therefore there by the sealing connection 15 between it matched drilled plate 9 and the tube 8 is replaced. Traceable at the lower end of the plate 9, the lower outwardly directed Randabkantung 10 with the open above (alternatively permeable) joint closure 12 to the plate 9 (in the form of a tile) held clothing element 5 and below the rigid joint closure 14 with respect to adjacent elements 5, at the upper end of the plate 9, the peripheral Randabkantung 11 and below the permanently elastic joint closure 13 relative to the held element 5 and above the rigid joint closure 14 with respect to adjacent elements 5 of the clothing 4. To the passage 7 of the tube 8 of a sheet of installation. 6 in the space-forming component 1 through the clothing 4, the permanently elastic closure 16 can be seen. The optionally only covering rosette 19 is not shown.

Installation pipes 8 must during the expansion of the sanitary installation as Roh- or pre-assembly 6 Rohbauerstellung, sometimes with later upgrades or extensions for the purpose of tap water, for other fittings from a space-forming component 1 (possibly from a laminating wall construction) with a Breakthrough 7 by the subsequent clothing 4 and by the thus broken at this point, later applied to the surface 2 of the component 1, surface seal 3 are guided into the room. The comprehen- sive rules required surface seal 3 (especially in a wet room) can be prepared ready to use after completion of Rohinstallation 6 and before component clothing 4 in the usual way up to the opening 7 and according to local conditions the requirements for recording the vibrations, temperature stresses and otherness the Rohinstallation 6 are sealed separately to protect the component 1. After completion of the clothing 4, which may be left to the breakthrough 7 without disadvantage, the plate 9, which matched by clothing mirror on the location and size of the element 5 of the clothing 4 to the tube 8 and drilled on the location and size of the tube 8 is inserted at this point and against stresses from the space inevitable incoming and penetrating water tight and congruent with its stresses are connected to the tube 8. It thus remains independent, but firmly and safely connected to the pipe even in its highly limited shape and position changes, so does not tear off from the tube 8, but catches water in the construction of the clothing 4 outside the flat seal 3, prevents one lateral spreading through their lateral, even by their upper edge edging 11 and derives it on their lower edge edgings 10 without damage and without contamination on the visible, shaping surface of the clothing 2 from.

Thus, the usual, technical procedure for flat seal 3 and 4 design of the room-side surface 2 of the component 1 can still be met by skilled craftsmanship, only with other, more effective means, namely for punctual Sealing the bushing 7 of the installation tube 8 through the plate 9 with simultaneous discharge inevitably penetrated water by the need for semi-open or open joint 12, which in addition to the protection of the substance of the component 1, a significantly increased protection for the construction of the clothing 4 and its space-facing surface 2 is ensured.

A rosette 19 for optical lamination of the opening 7 is not required, since it can be worked clean, especially since the visible remaining breakthrough 16 through the clothing element 5 no longer has to serve the purpose of a seal. The joint 16 remains only like a conventional joint 14 in the remaining element level of the clothing. 4

The tuned on type and level of clothing 4 plate 9 is kept as the rest of the material for the work to be performed and adapted to local requirements or safely prescribed coordination with a few, otherwise customary hand grips. By thus possible final performance increases the last adapted, verifiable and safe effective plate 9 accuracy and compensates especially small tolerances exposed joint division of the clothing 4 to the point of implementation 16 of the installation tube 8 at final assembly without much effort.
