Description

The present invention relates to a building protection according to the preamble of claim 1 and a pre-wall element according to the preamble of claim 7.

Pre-wall installations are used in a variety of ways, with use in the sanitary area in particular being used extensively. The advantage of such a pre-wall installation in the sanitary area is that all supply and sewage pipes are integrated into the pre-wall installation and are therefore invisible. This allows you to use a completely undisturbed cladding that can be designed according to any personal wishes. Usually, a plasterboard substructure is used for such a cladding, on which a tile mirror is applied. Another advantage is that you are independent of the structure and quality of the actual wall.

In order to build such a front wall installation, front wall elements are used which have a frame with an installation level for the cladding. In addition, the frame usually has fastening points for sanitary elements such as toilet, urinal, bidet, wash basin, washstand, flushing device for toilet and urinal and the like. These fastening points are mostly arranged in a standardized grid, the sanitary elements having corresponding fastening means corresponding to this grid.

It is also already known to use a structural protection for the inspection opening of a flushing device as part of the construction of the pre-wall installation. More precisely, when setting up the front-wall installation with, for example, a toilet, a front-wall element with a flushing device is used, which in turn has an inspection opening for maintaining the flushing device and for receiving an actuating device. After the pre-wall element has been aligned and fastened, a plasterboard substrate, for example, is fastened to the installation level of the pre-wall element, and a tile mirror is arranged thereon.

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

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

This object is achieved with the structural protection according to the invention according to claim 1 and the pre-wall element according to the invention according to claim 7. Advantageous further developments are given in the dependent claims and in the following description together with the figures.

On the part of the invention it was recognized that this object can be achieved in a surprisingly simple and cost-effective manner if a building protection is arranged around at least one connection of a water-carrying pipe. This means that the cladding can be installed without affecting the connection.

The structural protection according to the invention for a pre-wall element for the sanitary installation, the pre-wall element having a frame on which an installation level for the installation of a cladding (e.g. plasterboard and possibly tiled surfaces) of the pre-wall element exists, and at least one first connection for a water inlet and / or at least one having a second connection for a water drain, wherein the building protection is designed so that it can extend in relation to the installation level from the front wall element in a vertical direction beyond the installation level, is characterized in that the building protection has at least one opening to enclose one of the Has connections along its circumference.

If the structural protection has at least two openings for two connections, then the pre-wall element can be, for example, one for installing a toilet, shower toilet or urinal. If openings for the two connections are then arranged in a standardized manner, the building protection also represents a dimensional template for the alignment of the two connections within the framework of the pre-wall installation. This means that construction-related deviations can easily be recognized and compensated for.

In an advantageous development it is provided that there is a press fit between the opening and the connection. As a result, the building protection can be arranged particularly easily on the front wall element.

In an advantageous development it is provided that there is a fluid-tight seal on the opening for sealing the opening with respect to the connection, which seal is preferably designed as a lip seal or O-ring. This prevents a leak from being visible 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 via the interference fit.

In an advantageous development, it is provided that the structural protection has a side wall and / or a base, the side wall preferably protruding from the base, the connection between the side wall and the base being in particular fluid-tight. This means that building protection can be carried out in a particularly simple manner, e.g. can be produced by injection molding.

In an advantageous development it is provided that the side wall is designed to be closed. This makes the building protection particularly effective.

In an advantageous development it is provided that the base is designed to be closed apart from corresponding receptacles for the at least one connection. This makes the building protection particularly effective.

In an advantageous development it is provided that the base has at least one predetermined breaking point for the optional provision of an opening in the base, the predetermined breaking point preferably being designed such that it can be severed by breaking or cutting, the predetermined breaking point being in particular fluid-tight. As a result, the building protection can be adapted to specific requirements particularly easily and flexibly. 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 circumferential outer contour of one of the encompassed connections at least in some areas, the side wall in this area preferably being designed so that it does not rest on the connection outside the opening. As a result, leakage fluid is drained off particularly clearly and visibly. In addition, the building protection is particularly compact.

In an advantageous development it is provided that the side wall has such a lateral widening in an area between the openings that there is sufficient installation space for the openings. As a result, the building protection is designed to be particularly compact and inexpensive, while still ensuring sufficient installation space for any electrical system to be installed.

In an advantageous development, it is provided that the side wall is inclined at least in some areas, preferably having an inclination in the range from 0.5 ° to 2 ° with respect to the normal of the base, in particular an inclination of 1 ° with respect to the normal of the base. As a result, leakage fluid is drained particularly well in front of the cladding.

In an advantageous development it is provided that the side wall has at least one separating marking 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 front wall element, whereby the side wall of the building protection can be shortened so that the building protection is flush with the cladding or is slightly behind the visible level of the cladding. As a result, the building protection exists even when the pre-wall installation has been completed and any leakage fluid is always safely drained off in front of the cladding and thus quickly visible, so that appropriate maintenance measures can be taken promptly. The separating marking makes shortening very easy and standardized.

In an advantageous development it is provided that the structural protection is designed in one piece, preferably as an injection molded part. Then it is particularly easy and inexpensive to manufacture.

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, with a building protection consists, which extends in relation to the installation plane from the front wall element in the vertical direction beyond the installation plane, characterized in that the structural protection encloses at least one of the connections along its circumference.

In an advantageous development it is provided that the structural protection encloses at least two connections along their circumference, preferably encloses at least a first connection and a second connection along their circumference. Then the front wall element can for example be one for installing a toilet, shower toilet or urinal. If the structural protection has standardized openings for the two connections, it also represents a dimensional template for aligning the two connections in the context of the pre-wall installation. This means that construction-related deviations can be easily recognized and compensated for.

In an advantageous development it is provided that the building protection is designed in accordance with the building protection according to the invention.

In an advantageous development it is provided that there is a press fit between the opening and the connection. As a result, the building protection can be arranged particularly easily on the front wall element.

In an advantageous development it is provided that there is a fluid-tight seal between the building 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 invisible behind the cladding because leakage fluid is drained into the building protection and from there in front of the cladding.

In an advantageous development it is provided that the structural protection is plugged onto the at least one connection, with a press fit preferably being provided. As a result, the structural protection can be arranged on the front wall element in a particularly simple and, if necessary, also detachable manner.

The features and further advantages of the present invention will become clear in the following on the basis of the description of a preferred exemplary embodiment in connection with the figures. Purely schematically show:

• 1 the front wall element according to the invention in a perspective view from the front,
• 2 the pre-wall element according to the invention 1 in a side sectional view,
• 3 the section A. 2 in an enlarged view,
• 4th the building protection according to the invention in a perspective view from the front,
• 5 the building protection according to the invention side view and
• 6th the building protection according to the invention in a perspective view from behind.

The 1 to 3 show the wall element according to the invention 10 , in which 3 shows section A in a first enlarged illustration (left) and this in turn in a further enlarged illustration (right).

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

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

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

From the flushing device 24 a flush pipe extends downwards 36 that in a flushing arch 38 with a flushing water connection 40 ends. In the flushing water connection 40 is a flush water connector 42 used, with a lip seal for sealing 44 consists.

It is also located under the flushing water connection 40 a drain connection 46 on a drainage arch 48 that sits in a drain pipe 50 flows out. In the drain connection 46 is again a drain connector 52 used, with a lip seal for sealing 54 consists.

Both the drain connector 52 as well as the flushing water connector 42 are components that can be specially adapted for certain toilet types. They are not mandatory components of the pre-wall element according to the invention 10 . In the 1 and 2 they are only used to clarify their function and location, also with regard to building protection 66 shown.

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

The drain connection 46 is by means of a fastening device 62a , 62b on the lower horizontal strut 16a fixed. The flushing water connection 40 again is by means of the fastening device 64 in the usual way on the two vertical struts 56a , 56b attached.

Finally, on the pre-wall element 10 the building protection according to the invention 66 arranged. This building protection 66 is box-shaped and has a base area 68 and one along the perimeter of the base area 68 continuously extending side wall 70 on. The side wall 70 has an accordion-like fold 72 , creating numerous grooves 74 consist. These represent separation marks, each around the side wall 70 at an even distance from the base surface 68 are arranged. As a result, you can, for example, simply use a carpet knife to cover a panel (not shown) that is attached to the installation level I. (see. 2 ) of the pre-wall element 10 is arranged, protruding part of the side wall 70 cut off defined. Also the inspection opening protection 30th has corresponding separation marks (not shown).

Furthermore, the building protection 66 a first breakthrough 76 for the drain connection 46 and a second breakthrough 78 for the flushing water connection 40 on. Both the first breakthrough 76 as well as the second breakthrough 78 point perpendicular to the base plane 68 a peripheral wall 80 , 82 that extends over a sufficient depth for the drain connection 46 or flushing water connection 40 to enclose over a sufficient depth. The breakthroughs 76 , 78 have such an inside diameter that they have a press fit with the respective outside diameter of the drain connection 46 or flushing water connection 40 can form.

Also exist on the base surface 68 two more potential breakthroughs 84 , 86 , each from a predetermined breaking point 88 , 90 are surrounded so that these breakthroughs 84 , 86 can be exposed if necessary. The predetermined breaking points 88 , 90 are designed as embossed notches, so that the openings 84 , 86 simply by pushing out the corresponding locking pieces 92 , 94 can be formed. However, these notches are fluid-tight if they have not been damaged, so that no leaks can occur there.

The breakthrough 84 is from a side wall 96 and is used to accommodate a power supply unit that feeds the electrics of a shower toilet, for example. The breakthrough 86 in turn serves to accommodate an empty pipe, for example for a power supply cable.

The side wall 70 is with the base plane 68 over the seam 98 connected in one piece. The entire building protection 66 is made from a plastic material in an injection molding process inexpensively and easily, with the side wall 70 away from the base plane 68 outwardly conical at 1 ° to the normal of the base surface 68 expands, ie the circumference of the side wall 70 becomes larger, the further the corresponding peripheral section of the side wall 70 from the base plane 68 away.

• Zuerst wird der Rahmen 12 im Raum 22 definiert ausgerichtet und einnivelliert und anschließend mittels der Füße 18 und der Wandhalterungen 20 am Raum fixiert.

The building protection 66 and the pre-wall element 10 are now used as follows:

• First is the frame 12 in the room 22nd defined, aligned and leveled and then using the feet 18th and the wall brackets 20th fixed to the room.

The flushing device 24 with the flushing water connection 40 and the connecting pipe 50 with the drain connection 46 are already on the frame 12 , but only the fixings 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 using a sewer connection (not shown) in the room 22nd connected and the drain connection 46 closed with a plug (not shown) to prevent odors.

Now the building protection 66 so on the connections 46 , 40 postponed that there is an interference fit between the respective opening 84 , 86 and the associated connection 46 , 40 results. As a result, there is a relatively good seal against the passage of liquid at this fitting point, with a fluid-tight seal between the respective opening 84 , 86 and the associated connection 46 , 40 on the inside diameter of the opening 84 , 86 or on the outer diameter of the associated connection 46 , 40 Seals, for example in the form of elastic O-rings (not shown) can be arranged. Such an additional seal will mostly not be necessary because leakage fluid enters the room directly 22nd is derived as described below.

Because the breakthroughs 84 , 86 are arranged in a predetermined, ie standardized grid spaced apart from each other, provides the building protection 66 a dimension template for the arrangement of the flushing water connection 40 and drain connection 46 This automatically detects deviations in the relative position of the flushing water connection 40 opposite the drain connection 46 balanced.

Now the cladding is on the installation level I. of the pre-wall element 10 arranged and fixed. Then the core 34 from the inspection opening protection 30th removed and the side wall 32 of the inspection opening protection 30th and the side wall 70 of building protection 66 are at a corresponding mark 74 shortened so that these sidewalls 32 , 70 do not protrude from the cladding.

Then after removing the building plug, the drain connector 52 and the flush water connector 42 inserted, the corresponding toilet at the fastening points 58 fixed and drain connector 52 and Flush water connector 42 connected to the corresponding connections of the toilet.

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

Because the building protection 66 sealed on the two connections 46 , 40 is plugged in, any leakage fluid can escape from the connections 46 , 40 does not run undetected behind the cladding, but is in front of the cladding in the interior of the room 22nd derived so that such a leak can be quickly identified and treated. This is further supported by the fact that the side wall 70 not on the drain connector 52 and the flush water connector 42 and a conical expansion of 1 ° in relation to the normal of the base surface 68 has, whereby leakage fluid easily from the building protection 66 in the room 22nd is derived.

The building protection 66 does not need to be further secured because the press fit ensures a very good hold on the connections 40 , 46 consists. In addition, the side wall extends 70 over a short section 70a across the base 68 still at the back, which means the building protection 66 very good on the fasteners 62a , 62b , 64 can support.

The pre-wall installation created (not shown) remains particularly flexible even after its completion, in that it can later be changed from a normal toilet to a shower toilet, for example, because of the structural protection 66 the necessary installation space for the electrics is already reserved and free. If, during the installation of the pre-wall, corresponding empty conduits and corresponding empty cables with blind connections for the electrical system are laid, the electrical system, including power supply units and the like, can be used after the respective locking pieces have been broken out 92 , 94 can also be laid and connected at a later date.

From the above illustration it has become clear that the present invention provides an improved and more flexible front-wall installation. More precisely, with the help of the building protection according to the invention 66 that achieved the connections 40 , 46 for flushing water supply and / or waste water discharge are not impaired by the installation, installation space for a subsequent installation of electrics is retained and leaks are quickly detected. Furthermore, the building protection 66 comparatively environmentally friendly because it is not removed again, but on the front wall element according to the invention 10 remains and only a small protruding part of its side wall 70 Will get removed. In addition, the building protection 66 relatively compact because the side wall 70 at least in regions 100, 102 of the circumferential outer contour of the enclosed connections 40 , 46 is formed following and in the area 104 between the breakthroughs 76 , 78 only such a lateral expansion 106 has that sufficient installation space for the openings 84 , 86 for optional electrical installation. The base surface 68 follows the course of the side wall 70 .

Unless otherwise stated, all features of the present invention can be freely combined with one another. Unless otherwise stated, the features described in the description of the figures can also be freely combined with the other features as features of the invention. Objective features of the building protection 66 also within the framework of the pre-wall element 10 Find use and features of the pre-wall element 10 for a more detailed definition of features of building protection 66 be used.
