Arrangement and method for installing a tap angle 86659

The invention relates to an arrangement for installing a tap angle according to the preamble of claim 1.

The invention also relates to a method for installing a tap angle.

According to current building recommendations, residential water-10 pipes should be easily replaceable. In addition, any leakage should be easily and immediately noticeable from inside the apartment. Thus, according to the prior art, the water pipes placed behind the inner wall plate are placed inside the protective pipe and the protective pipe 15 in turn is connected to the so-called faucet angle box. The tap box leads to the apartment space of the leaked water. The faucet corner box is typically fastened to the interior structures of the wall with screws. According to the state of the art, a faucet corner, which is made of solid metal, typically brass, is also attached to the faucet corner box. 20 The function of the faucet angle is to turn the pipes running parallel to the walls perpendicular to the walls. In addition, the function of the entire existing faucet corner unit is to act as a support structure relatively lightly to support the internal water structure to the internal wall structure to facilitate the installation of plumbing fixtures located in the room-25 space.

The problem with the prior art is that the faucet corner box has to be built massive because it must be able to support the weight of the entire 30 faucet corners. For this reason, supporting the box to the wall structure is a time-consuming operation and, in addition, the price of the box becomes quite high.

The invention is based on the fact that the faucet corner box is lightweight and preferably fastened to the inner wall by lightweight studs.

The installation method according to the invention, on the other hand, is based on the fact that the faucet angle is supported directly on the inner wall and not on the 2 86659 faucet corner box.

More specifically, the arrangement according to the invention is characterized by what is set forth in the characterizing part of claim 1.

The method according to the invention, in turn, is characterized by what is set forth in the characterizing part of claim 7.

The invention provides considerable advantages.

With the solution according to the invention, it is possible to build a faucet corner box with a very light structure. Thus, the cost per 15 boxes will be reduced to a fraction of the current level, especially when manufacturing large series. Installation is also facilitated because the faucet corner box can be pre-attached to the inner wall plate at an early stage and the faucet corner box does not necessarily have to be installed with cumbersome installation means, but at best lightweight mounting pins can serve as the final installation means.

The invention will now be examined in more detail with the aid of exemplary embodiments according to the accompanying figures.

Figure 11 shows a side view of an alternative installation solution according to the invention.

According to Fig. 1, the faucet corner box 1 is fixed outside the steel sheet wall 2 in a substantially splash-proof manner. According to the recommendations in use, the tightness requirement is that in the event of a possible leak, a leak is detected inside the wall 2. The faucet angle 10 is fixed to the sheet steel wall 2 by means of a clamping ring 12. A cover washer 47 is further mounted between the clamping ring 25 and the wall. The clamping ring 12 is tightened by means of the threads 13 of the threaded part 28 of the tap corner 10. Between the faucet corner 10 and the wall 2, a support damper 11 is used, especially in connection with heavy bathroom furniture, which prevents the steel wall from pitting 30 from the load of the bathroom furniture. However, the support damper 11 has a hole corresponding to the mounting hole of the wall 2 so that when installed the support damper 11 descends on its flange 42 against the upper surface of the faucet corner box, whereby the upper edge of the support damper 11 rests against the upper surface of the faucet corner 10. Thus, a circular mounting hole is formed on the faucet angle 10.

Thus, the support damper 11 is not fixedly fixed to the wall structure 2, but is pressed between the tap angle flange 17 and the wall 2 in connection with the fixing of the tap angle 10. The flange 17 of the fastening 86659 4 preferably consists of fastening spreads located above and below the tap corner 10. For installation reasons, there are no fastening spreads on the sides of the tap corner 10. Due to the shape and location of the fastening spreads 17, a vertical support surface 45 is formed on both sides of the tap corner 10, which rests on the support projections 37 of the tap corner box 1. The support projections 37 lock the tap angle 10 in the lateral direction. A protective cone 14 is also mounted inside the wall 2, which covers the mounting opening 19, 10 under the clamping ring 12 and part of the threaded part 28 of the tap corner.

The lightweight faucet corner box 1 surrounds the outside corner wall 25 of the faucet corner 10 and this connector 15, to which the water line 4 is attached by means of a clamp 6. The cavity of the faucet corner box 1 surrounding the corner part 25 is referred to here as the inner cavity 20. A flow opening 40 is arranged below the mounting opening of the wall 2, from which water entering the inner cavity 20 of the faucet corner box 1 due to possible leakage is led indoors. The protective tube 5 of the water pipe 4, in turn, is attached to the connector 3 of the faucet corner box, which has gripping teeth for the protective tube 5 according to the prior art.

Thus, the faucet angle 10 is completely separate from the faucet corner box 1 itself, and thus does not load the faucet corner box 1 with its weight, as is the case in the structures according to the prior art. Thus, the faucet corner box 1 can be fixed to the wall 2 by very light means 25.

According to Figure 2, the tap corner box 1 comprises flange-like projections 16 on both sides of the cavity 20. The tap corner box 1 is fixed to the holes 18 in the partition wall 2 by pins 35 formed in the flanges 16. The circular cross-section pins 35 are provided with transverse locking grooves intended to lock into the partition wall 2. The maximum diameter of the pins 35 is about 2% larger than the mounting holes 18. The cross-section of the locking grooves is equilateral three-35 in shape. To enhance the locking, locking grooves can also be used, in which the locking wall of the groove is parallel to the partition wall 2. The mounting grooves 49 of the support plate 11 for the pins 35 are vertical and elongate so that the support plate 11 5 86659 can be moved. For technical reasons, the upper part of the tap corner 10 is drawn in spite of the support plate 11. The mounting hole 19 of the faucet corner 10 in the wall 2 is arranged sufficiently wide to allow the faucet corner 10 to be moved vertically during the installation phase. When the clamping ring 12 of the faucet corner 10 is released, the support plate 11 also moves freely upwards, whereby the faucet angle 10 can be lifted upwards and then pulled inside the partition wall 2. The width of the inner cavity 20 of the faucet corner box 1 at the faucet corner 10 10 is approximately equal to the mounting opening 19 of the wall 2 due to the support projections 37.

The tap corner box 1 is made of plastic by an injection molding method. A suitable material is, for example, polypropylene which is sufficiently elastic and strong. Alternatively, the hanakul marasia 1 can be screwed or glued from its flange 16 to the outer surface of the partition 2.

Figures 3 to 5 show typical sizing options for a faucet box according to the invention.

According to Figure 3, the radius r1 of the circular flange 16 of the tap corner box is about 35 mm, the maximum width of the inner cavity 20 is about 40 mm and the radius of curvature 25 r2 of the upper and lower roundings of the inner cavity 20 is about 20 mm. The width of the inner cavity 20 at the support projections 37 is about 27 mm. There are a total of four locking pins 35, in pairs on either side of the inner cavity 20. The distance between the pins 35 in the vertical direction is about 20 mm and in the horizontal direction about 50 mm.

According to Figure 4, the depth of the inner cavity 20 is about 40 mm and the height is about 70 mm. The diameter of the connector 3 is approx. 20 mm and the height approx. 25 mm. The wall thickness of the tap corner box 1 is approx. 2 mm.

According to Figure 5, the flange 16 extends a maximum of about 15 mm outwards from the edges of the inner cavity 20.

35 6 86659

According to Figure 6, the mounting pins 35 have a height of about 5 mm and a maximum width of about 5.1 mm. The tip of the pin 35 is in the shape of a truncated cone, whereby the apex angle of the cone is about 60 *. The locking grooves 30 have a width of about 1 mm and a depth of about 0.5 mm. Luki-5 tusuria 30 has two pieces.

According to Figures 7-9, the width of the tap corner 10 is about 26.6 mm. The total height of the flange part 17 is about 37 mm. The faucet angle 10 according to the figures is provided with a connector 15 for a 15 mm plastic hot water pipe. The long threaded part 28 is particularly suitable for attaching a shower mixer and a washing machine tap.

The faucet angle solution according to Fig. 10, which has a smaller (12 mm) connector 15 for hot water and a short threaded part 28 ', is particularly suitable for the installation of toilet seats and kitchen Cu pipes.

Fig. 11 shows an installation solution 20 similar to Fig. 1 for attaching the faucet angle 10 to the Cu pipes of the washbasin and toilet seat and kitchen. Due to the lighter mechanical load, the support plate shown in Figure 1 is not required for installation.

25 Zinc loss resistant brass is used as the material for the tap corner 10.
