EP4185751B1 - Construction guard and pre-wall element with a construction guard - Google Patents

Description

The present invention relates to a building protection according to the preamble of claim 1, a pre-wall element according to the preamble of claim 8 and a method for constructing a pre-wall installation according to claim 12.

Pre-wall installations are used in a variety of ways, with the use in sanitary facilities being particularly extensive. The advantage of such a pre-wall installation in sanitary facilities is that all supply and drainage pipes are integrated into the pre-wall installation and are therefore invisible. This means that you can use a completely undisturbed cladding that can be designed to suit any personal wishes. A plasterboard substructure is usually used for such a cladding, onto which a tiled surface is applied. Another advantage is that you are independent of the structure and quality of the actual wall.

To set up such a pre-wall installation, pre-wall elements are used that have a frame with an installation level for the cladding, whereby the frame can be attached to a wall of a room. In addition, the frame usually has attachment points for sanitary elements such as toilets, urinals, bidets, washbasins, vanity units, flushing devices for toilets and urinals, etc. These attachment points are usually arranged in a standardized grid, whereby the sanitary elements have corresponding attachment means corresponding to this grid.

It is also already known to use a building protection for the inspection opening of a flushing device when constructing the pre-wall installation. More precisely, when constructing the pre-wall installation with, for example, a toilet, a pre-wall element with a flushing device is used, which in turn has an inspection opening for servicing the flushing device and for accommodating an actuating device. After aligning and fastening the pre-wall element, a plasterboard substrate is attached to the installation level of the pre-wall element, for example, and a tiled surface is arranged on it.

During the installation of the cladding, dirt and dust can enter the inspection opening. To prevent this, a construction protection is usually inserted into the inspection opening to cover this opening. After the installation of the cladding is complete, this construction protection is removed again and the actuating device is then inserted into the inspection opening.

The EP 2 105 544 A1 , against which claim 1 was defined, relates to a fire protection element that is intended to securely close the openings for the flush pipe and drain pipe in the event of a fire. For this purpose, the fire protection element has intumescent material in strip form that is arranged between two metal plates.

The EP 3 258 020 A1 concerns a construction protection that is intended to protect several connections at the same time from dust and particles during installation work.

The AT 11 695 U1 describes a wall block that is made of foam and in which pipe sections with corresponding connections are embedded. The connections are surrounded by a sleeve-shaped protective element that protrudes above the installation level and is sealed at the back with a sealing element so that no water can run into the wall.

The object of the present invention is to improve the pre-wall installation and make it more flexible.

This object is achieved with the building protection according to the invention according to claim 1, the pre-wall element according to the invention according to claim 8 and the method according to the invention for constructing a pre-wall installation according to claim 12. Advantageous further developments are specified in the subclaims and in the following description together with the figures.

The inventors realized that this problem can be solved in a surprisingly simple and cost-effective way by arranging a common construction protection around at least one connection of a water pipe and at least one other connection, because this creates a uniform construction protection for these two connections. This allows the installation of the cladding without affecting the The construction protection can also be made very compact and the installation of the pre-wall installation can be carried out quickly and inexpensively. "Water-conducting" can mean both water supply and water drainage.

The building protection according to the invention for a pre-wall element for sanitary installation is defined in claim 1.

Since the building protection has at least two openings for the first connection and the second connection, the pre-wall element can, for example, be one for the installation of a toilet, shower toilet or urinal.

In an advantageous further development, at least one opening is designed to fix the position of a connection within the building protection, so that there is no need to fear any positional deviations of the connection in relation to the geometry of the building protection. If the building protection is then arranged in a predetermined position on the pre-wall element, the position of the connection relative to the pre-wall element is thus defined.

In an advantageous further development, the building protection is designed to fix the position of two connections within the building protection, making it suitable for the enclosed connections form a template so that there is no need to worry about positional deviations between the connections. If the openings for the two connections are arranged in a standardized manner, the building protection also represents a dimensional template for the alignment of the two connections as part of the pre-wall installation. This makes it easy to identify and compensate for construction-related deviations. This option can be used alternatively or in addition to a predetermined position of the building protection on the pre-wall element. The standardized arrangement can involve a standardized distance between the two openings and/or a standardized position of at least one opening within the building protection.

In an advantageous further development, there is a press fit between the opening and the connection. This makes it particularly easy to arrange the building protection on the pre-wall element.

According to the invention, there is a fluid-tight seal at the opening to seal the opening from the connection, which is preferably designed as a lip seal or O-ring. This prevents a leak from being invisible behind the cladding because leakage fluid is drained into the building protection and from there in front of the cladding. The fluid-tight seal can also be provided by the press fit.

According to the invention, the building protection has a side wall and a base, the side wall protruding from the base, the connection between the side wall and the base being fluid-tight. This makes it particularly easy to produce the building protection, e.g. by means of injection molding.

According to the invention, the side wall is designed to be closed. This makes the construction protection particularly effective.

According to the invention, the base is designed to be closed except for corresponding receptacles for at least one connection. This makes the construction protection particularly effective.

In an advantageous development, it is provided that the base has at least one predetermined breaking point for optionally providing an opening in the base, wherein the predetermined breaking point is preferably designed such that it can be severed by breaking or cutting, wherein the predetermined breaking point is in particular designed to be fluid-tight. This allows the building protection to be adapted to specific requirements in a particularly simple and flexible manner. For example, there can be a predetermined breaking point for an opening for arranging an empty pipe for a power supply cable and a predetermined breaking point for an opening for arranging a power supply unit for a shower toilet.

In an advantageous development, it is provided that the side wall is designed to follow the peripheral outer contour of one of the enclosed connections at least in some areas, wherein in this area the side wall is preferably designed such that it does not rest against the connection outside the opening. This drains off leakage fluid particularly well and visibly. In addition, the construction protection is designed to be particularly compact.

In an advantageous further development, the side wall in an area between the openings has such a lateral widening that there is sufficient space for the openings. This makes the building protection particularly compact and cost-effective, while still ensuring sufficient space for any electrical equipment that may need to be installed.

In an advantageous further development, the side wall is inclined at least in some areas, preferably with respect to the normal of the base, an inclination in the range of 0.5° to 2°, in particular an inclination of 1° with respect to the normal of the base. This allows leakage fluid to be drained particularly well in front of the panel.

In an advantageous further development, it is provided that the side wall has at least one separation mark for separating a part of the building protection, which is preferably designed as a continuous groove or fold. As a result, the building protection does not have to be removed again after the cladding has been arranged, but can remain on the pre-wall element, whereby the side wall of the building protection can be shortened in such a way This means that the construction protection is flush with the cladding or slightly behind the visible level of the cladding. This means that the construction protection is maintained even when the pre-wall installation is completed and any leakage is always safely diverted in front of the cladding and is therefore quickly visible, meaning that appropriate maintenance measures can be taken promptly. The separation marking makes shortening very easy and standardized.

In an advantageous further development, the structural protection is designed as a single piece, preferably as an injection-molded part. It is then particularly easy and cost-effective to manufacture.

In an advantageous further development, it is provided that the building protection has a fastening option for electrical and/or electronic components, whereby the fastening option is preferably at least partially on the back (the part of the building protection that is at the back in relation to the paneling) of the building protection. Then, for example, a power supply unit for the electrics of a shower toilet can be arranged there in a space-saving and defined manner. If the component is arranged exclusively on the back, it can be protected against leaks. On the other hand, an opening in the building protection for mounting the component could also exist or be formed, so that the component can be attached to the building protection if necessary after the pre-wall installation has been set up, for example when changing from a toilet installation to a shower toilet installation.

Independent protection is claimed for the pre-wall element according to the invention for the sanitary installation with a frame on which there is an installation level for the installation of a cladding of the pre-wall element, and at least one first connection for a water inlet and/or at least one second connection for a water outlet, wherein the pre-wall element has a building protection according to the invention.

Since the building protection encloses at least a first connection and a second connection along their circumference, the pre-wall element can be one for installing a toilet, shower toilet or urinal, for example. If the building protection has standardized openings for the two connections, it also represents a dimensional template for the alignment of the two connections as part of the pre-wall installation. This makes it easy to identify and compensate for construction-related deviations.

In an advantageous further development, there is a press fit between the opening and the connection. This makes it particularly easy to arrange the building protection on the pre-wall element.

In an advantageous development, there is a fluid-tight seal between the structural protection and the at least one connection, the seal preferably being designed as a press fit and/or as a lip seal or O-ring. This prevents a leak from being visible behind the cladding because leakage fluid is diverted into the structural protection and from there in front of the cladding.

In an advantageous further development, the building protection is attached to the at least one connection, preferably with a press fit. This makes it particularly easy to arrange the building protection on the pre-wall element and, if necessary, also detachably.

Furthermore, independent protection is claimed for the method according to the invention for constructing a pre-wall installation, which is characterized in that at least one water-carrying connection is arranged on a frame of a pre-wall element and the The building protection according to the invention is arranged in such a way that it encloses the water-carrying connection with a first opening and another connection with a second opening, after which a cladding of the pre-wall element is arranged.

The construction protection is therefore only installed during the pre-wall installation itself to enclose the water-carrying connection. In this respect, it is not pre-installed on the pre-wall element before the pre-wall installation is set up, but is arranged separately from the frame. This allows for particularly flexible responses to requirements that arise during installation. In addition, it is possible to decide individually whether or not such construction protection is used, so that not every pre-wall element has to be delivered with construction protection, but this can be added optionally.

In an advantageous further development, it is provided that one or more further installation measures, preferably a fastening of the frame to a wall, are carried out before the arrangement of the building protection and/or that one or more further installation measures, preferably the final fixing of one of the connections enclosed by the building protection to the frame, are carried out between the arrangement of the building protection and the arrangement of the cladding of the pre-wall element.

The Figures 1 to 3 show the pre-wall element 10 according to the invention, wherein Fig. 3 shows section A in a first enlarged view (left) and this in turn in a further enlarged view (right).

The Figures 4 to 6 again show the building protection 66 according to the invention in different views.

It can be seen that the pre-wall element 10 according to the invention has a frame 12 which consists of two vertical struts 14a, 14b and three horizontal struts 16a, 16b, 16c. Height-adjustable feet 18 are arranged on the vertical struts 14a, 14b. In addition, there are wall brackets 20 on the frame in the area of the upper horizontal strut 16c. With the help of the feet 18 and the wall brackets 20, the pre-wall element 10 can be aligned and fixed in a room 22 in the usual way.

A flushing device 24 is fixed in the frame 12, which is provided in the usual way with a tank 26 and a valve (not shown) located inside it. In the flushing device 24 there is an inspection opening 28, which is closed here by an inspection opening protection 30. The inspection opening protection 30 is snapped into the inspection opening 28 and has a circumferential side wall 32 and a core 34 made of expanded polystyrene (EPS), for example, arranged therein for temporary stiffening.

A flushing pipe 36 extends downwards from the flushing device 24 and ends in a flushing bend 38 with a flushing water connection 40. A flushing water connector 42 is inserted into the flushing water connection 40, with a lip seal 44 being provided for sealing.

Furthermore, there is a drain connection 46 under the flush water connection 40, which is located on a drain bend 48 that opens into a drain pipe 50. A drain connector 52 is again inserted into the drain connection 46, and here too there is a lip seal 54 for sealing.

Both the drain connector 52 and the flush water connector 42 are components that can be specially adapted for certain types of toilet. They are not mandatory components of the pre-wall element 10 according to the invention. In the Fig.1 and 2 They are shown only to clarify their function and location in relation to building protection 66.

Between the two horizontal struts 16a, 16b there are two vertical struts 56a 56b, which have fastening points 58 for the fastening of the toilet and shower toilet (not shown) and a fastening point 60 for the installation of a shower water connection (not shown) for a shower toilet.

The drain connection 46 is fixed to the lower horizontal strut 16a by means of a fastening device 62a, 62b. The flush water connection 40 is in turn fastened to the two vertical struts 56a, 56b in the usual way by means of the fastening device 64.

Finally, the building protection 66 according to the invention is arranged on the pre-wall element 10. This building protection 66 is box-shaped and has a base surface 68 and a side wall 70 that extends continuously along the circumference of the base surface 68. The side wall 70 has an accordion-like fold 72, which creates numerous grooves 74. These represent separation marks, which are each arranged around the side wall 70 at a uniform distance from the base surface 68. This means that it is possible, for example, to simply use a carpet knife to cut the panel (not shown) that is attached to the installation level I (cf. Fig. 2 ) of the pre-wall element 10, the protruding part of the side wall 70 is separated in a defined manner. The inspection opening construction protection 30 also has corresponding separation markings (not shown).

Furthermore, the construction protection 66 has a first opening 76 for the drain connection 46 and a second opening 78 for the flushing water connection 40. Both the first opening 76 and the second opening 78 have a peripheral wall 80, 82 perpendicular to the base surface 68, which extends over a sufficient depth to enclose the drain connection 46 or flushing water connection 40 over a sufficient depth. The openings 76, 78 have such an inner diameter so that they can form a press fit with the respective outer diameter of the drain connection 46 or the flush water connection 40.

In addition, there are two further potential openings 84, 86 on the base surface 68, each of which is surrounded by a predetermined breaking point 88, 90, so that these openings 84, 86 can be exposed if necessary. The predetermined breaking points 88, 90 are designed as embossed notches, so that the openings 84, 86 can be formed simply by pressing out the corresponding closure pieces 92, 94. However, these notches are fluid-tight if they have not been damaged, so that no leaks can occur there.

The opening 84 is surrounded by a side wall 96 on the rear side 95a (the side that faces the wall when the building protection 66 is installed, while the front side 95b of the base surface 68 faces the sanitary element to be installed, such as a toilet or shower toilet) of the base surface 68 and serves to accommodate a power supply unit that, for example, feeds the electrical system of a shower toilet. The opening 86 in turn serves to accommodate an empty pipe, for example for a power supply cable.

The component is thereby held in the opening 84 and between the side walls 96 by a press fit, but could also be attached to the side wall 96 by separate fastening means such as screws and the like. The opening 84 makes it possible to arrange the component later, for example when converting the pre-wall installation from a toilet to a shower toilet.

If, however, the component is to be used from the beginning, it could also be attached only to the side wall 96, with the opening 84 remaining closed. The electrical connections for, for example, a shower toilet could then be led through an empty pipe in the opening 86, so that the component would be arranged on the building protection 66 in a leak-proof manner.

The side wall 70 is integrally connected to the base surface 68 via the seam 98. The entire construction protection 66 is manufactured inexpensively and simply from a plastic material using an injection molding process, with the side wall 70 widening outwards from the base surface 68 conically at 1° relative to the normal of the base surface 68, ie the The circumference of the side wall 70 becomes larger the further the corresponding circumferential portion of the side wall 70 is from the base surface 68.

The building protection 66 and the pre-wall element 10 are now used as follows:
First, the frame 12 is aligned and leveled in the room 22 and then fixed to the room 22 by means of the feet 18 and the wall brackets 20.

The flushing device 24 with the flushing water connection 40 and the connecting pipe 50 with the drain connection 46 are already located on the frame 12, although only the fastenings 62a, 62b of the drain connection 46 are fixed, while the fastening device 64 for the flushing water connection 40 is still slightly variable vertically. The connecting pipe 50 is now connected to a waste water connection (not shown) in the room 22 and the drain connection 46 is closed with a construction plug (not shown) to prevent odors. The flushing water connection 40 can also be closed with a construction plug (not shown).

The construction protection 66 is now pushed onto the connections 46, 40 in such a way that a press fit is created between the respective opening 84, 86 and the associated connection 46, 40. This results in a relatively good seal against the passage of liquid at this fitting point, whereby seals, for example in the form of elastic O-rings (not shown), can be arranged on the inner diameter of the opening 84, 86 or on the outer diameter of the associated connection 46, 40 for a fluid-tight seal between the respective opening 84, 86 and the associated connection 46, 40. However, such additional sealing will usually not be necessary because leakage liquid is drained directly into the space 22, as described below.

Since the openings 84, 86 are arranged at a distance from one another in a predetermined, ie standardized grid and fix the position of the connections 40, 46 through the press fits, the construction protection 66 represents a dimensional template for the arrangement of the flush water connection 40 and the drain connection 46. This automatically compensates for deviations in the relative position of the flush water connection 40 compared to the drain connection 46. Since the drain connection 46 is already fixed to the frame 12 was, the flush water connection 40 is now fixed in its vertical position exactly to the size in relation to the drain connection 46, whereby this dimension is coordinated with standardized toilets or shower toilets, so that their installation no longer causes any problems.

After fixing the fastening 64 for the flush water connection 40, the cladding is now arranged and fixed on the installation level I of the pre-wall element 10. The core 34 is then removed from the inspection opening protection 30 and the side wall 32 of the inspection opening protection 30 and the side wall 70 of the protection 66 are shortened at a corresponding marking 74 so that these side walls 32, 70 do not protrude beyond the cladding.

Then, after removing the construction plug of the drain connection 46, the drain connector 52 and, if necessary, after removing the construction plug of the flush water connection 40, the flush water connector 42 are inserted, the corresponding toilet is fixed to the fastening points 58 and the drain connector 52 and flush water connector 42 are connected to the corresponding connections of the toilet.

Finally, a suitable actuating device (not shown) is connected to the flushing device and inserted and fixed in the inspection opening 28.

Because the structural protection 66 is sealed onto the two connections 46, 40, any leakage fluid from the connections 46, 40 cannot run undetected behind the paneling, but is drained in front of the paneling into the interior of the room 22 so that such a leak can be quickly detected and treated. This is further supported by the fact that the side wall 70 does not rest against the drain connector 52 and the flush water connector 42 and has a conical widening of 1° in relation to the normal of the base surface 68, whereby leakage fluid is easily drained from the structural protection 66 into the room 22.

The construction protection 66 does not need to be secured further because the press fit ensures a very good hold on the connections 40, 46. In addition, the side wall 70 extends over a short section 70a beyond the base surface 68 to the rear, whereby the construction protection 66 can be supported very well on the fastening devices 62a, 62b, 64.

Alternatively, the construction protection 66 could also be attached separately to the frame 12, whereby a fastening defined with regard to the exact position is also possible, whereby an adjustment of the fastening of the drain connection 46 to the frame 12 could be carried out if necessary.

The pre-wall installation created (not shown) remains particularly flexible even after it has been completed in that it is still possible to switch from a normal toilet to a shower toilet later, for example, because the building protection 66 already reserves and keeps the necessary installation space for the electrics. If the corresponding empty pipes and empty cables with blind connections for the electrics are laid during the installation of the pre-wall, the electrics, including power supplies and the like, can also be laid and connected later after the respective closure pieces 92, 94 have been broken out.

From the above description it has become clear that the present invention provides an improved and more flexible pre-wall installation. To be more precise, the inventive construction protection 66 ensures that the connections 40, 46 for flushing water supply and/or waste water drainage are not impaired by the installation, installation space is retained for subsequent installation of electrical equipment and leaks are quickly identified. Furthermore, the construction protection 66 is comparatively environmentally friendly because it is not removed again, but remains on the inventive pre-wall element 10 and only a small protruding part of its side wall 70 is removed. In addition, the construction protection 66 is relatively compact because the side wall 70 is designed to follow the peripheral outer contour of the enclosed connections 40, 46 at least in areas 100, 102 and in the area 104 between the openings 76, 78 only has such a lateral widening 106 that there is sufficient installation space for the openings 84, 86 for optional installation of electrical equipment. The base surface 68 follows the course of the side wall 70.
