Description

arrangement of pipelines

The invention relates to an arrangement of pipelines as characterized in the preamble of claim 1.

In conventional sanitary installations with metal pipes, a line with the required cross-section for the cold water and two lines for the supply and for the circulation of the warm water have hitherto been arranged for the riser. The usual con- . The construction is that risers are installed with a flow cross section that decreases upwards from floor distributor to floor distributor. Among other things, this leads to the disadvantage that one has to work with a large number of different pipe dimensions, which requires different floor distributors, fittings and pipe sections and which makes both the construction and the assembly work more difficult. It is also known to arrange separate risers either for each floor or for several floors together, with no uniform pipe and distribution system being required here either.

f OMPI System with the same components is applicable.

In order to prevent excessive changes in length due to temperature differences, expansion compensators, known e.g. from CH-PS 532 746 or ÜS-PS 29 11 238, had to be used in the risers. In newer sanitary installations, bendable copper pipes, thin-walled mild steel to stainless steel pipes or plastic pipes are often used, in which case several pipes with a smaller cross-section can then also be installed. However, this requires an expansion compensator for each pipe, which means that the advantages of several lines with smaller cross-sections are no longer given.

The object of the present invention is to create a space-saving arrangement of pipelines in risers which allows the use of several identical, flexible pipes of the same cross-section and the same floor distributor for all floors.

In addition, without the use of expansion compensators, a compact laying of several pipelines that can be isolated without great effort is to be ensured.

According to the invention, this is achieved by the teaching specified in patent claim 1.

Particularly advantageous configurations are characterized in the dependent claims.

Due to the circular arrangement of several risers

OMPI From floor distributor to floor distributor, several lines of the same dimensions can be arranged with good use of space, with all floor distributors being of the same design. This creates a compact riser that is easy to isolate and cover.

Since the floor distributors are firmly anchored in the building, there is no need for an additional holder for the flexible pipes if the individual floors are of normal height, which considerably simplifies assembly. The sufficiently large distance between the fixed points of the riser pipes allows them to bend out slightly to the side if there are changes in length due to temperature differences.

«

Advantageously, the riser pipes are arranged helically in the longitudinal direction, which facilitates their lateral deflection and also allows the pipes to be shortened when the temperature drops without damaging them.

In the case of large distances between the floor distributors, the riser pipes are advantageously guided again in between in holders, the holders being arranged fixedly or displaceably and/or rotatably on a longitudinal beam. The movable holder facilitates changes in the length of the risers.

The longitudinal support, which is advantageously designed as a tube, can at the same time form the drain pipe. The invention is shown in the drawings in various variants and described below.

1 and 2 show a partial section of a riser 1 for supplying several floors of a building with cold and warm water. Several identical risers for cold water 2a and for warm water 2b are arranged in a circle around a riser axis 3 and go from the respective supply line to the floor distributors 4, which are arranged in each floor and are of the same design.

The floor distributor 4 consists of two Gehäuse¬ share 5a, 5b, the parting line 11 in the direction of Riser axis 3 runs. The preferably semicircular housing parts 5a, 5b each have a chamber 6a, 6b, to which the incoming and continuing risers 2a and 2b are connected by means of detachable connections 7. Each housing part 5a, 5b has at least one branch piece 8a, 8b, to which a shut-off valve (not shown) and a distribution piece for connecting the individual consumers are attached.

The two housing parts 5a, 5b are clamped by means of clamping screws 9 to a retaining piece 10 anchored in the wall, with an insulating gap 11 created by the parting line 11 being present between the two housing parts 5a, 5b. In the exemplary embodiment shown, the holding piece 10 has a pipe 12 which can also be designed as a drain pipe, with an insulating material 13 being inserted between the drain pipe and the housing parts 5a, 5b to reduce heat losses.

The chamber 6a connects all riser pipes 2a for cold water at each floor distributor 4, so that the entire quantity of water flowing in the riser pipes 2a is available to the consumer on every floor. In the case of the pipelines 2b for hot water, it is advantageous that at least one line runs as a circulation line directly into the floor distributor 4 of the top floor. However, so that the same prefabricated line pieces with the same cross section and the same length can be used, this circulation line is also advantageously connected to the housing part 5b of each floor distributor 4. between the two detachable connections of this line in the chamber 6b, a piece of pipe 14 producing a direct connection of the line is then inserted (see FIG. 1).

A Venturi effect is created by providing a small bore 15, which is advantageously not larger than 1/10 of the flow cross section of the pipe piece 14 in cross section. This should cause a within the chamber 6b and the branch piece 8b

Circulation of the hot water takes place. The same effect also arises if a cross-sectional constriction is arranged in the tube section 14 and a larger, radial borehole is arranged behind this, viewed in the direction of flow.

In the case of the floor distributor 4 arranged on the top floor, the piece of pipe 14 is omitted, as a result of which the circulation line is then connected to the other risers. In addition, the connections for further risers are closed by screw plugs on the detachable connections 7 on the top floor distributor.

Clamping the individual floor distributors 4 to the holding piece 10 or pipe 12 offset at an angle to one another results in a helical arrangement of the riser pipes 2a, 2b, which makes it easier for the riser pipes, which are preferably made of plastic, to bend out when there are changes in length due to temperature changes. This saves the use of expansion compensators.

OMPI Of course, one of the cold water lines 2a can also be designed as a continuous line up to the top floor by inserting pipe sections 14, so that a ring line is created which causes a direct supply of the consumers on the top floor or the upper floors.

A further variant embodiment is shown in FIGS. 3 and 4, which shows a compact arrangement of riser tubes 2a, 2b for cold and hot water. The floor distributor 4 consists of a three-part housing 20 with joints 19 running transversely to the riser axis 3. The risers 2a and 2b are connected to the upper housing part 21 and the lower housing part 23 by means of detachable connections 7 or non-detachable connections ¹⁷ , such as soldering , welded or glued joints connected. The branch pieces 8a and 8b emanating from the two chambers 6a and 6b are attached to the central housing part 22 . In the area of the parting lines 19, the housing parts 21, 22, 23 have flanges 24, which are engaged by two-part shell couplings 25, by means of which the housing parts 21 and 22 or 22 and 23 are firmly connected. A seal 26 is inserted between the housing parts 21 and 22 or 22 and 23, which at the same time also seals the two chambers 6a and 6b from one another. The housing parts can also be connected, for example, by means of screws or another type of connection. The floor distributor 4 shown in FIGS. 3 and 4 has a circular cross section, with the two chambers 6 a , 6 b having a semicircular cross section and being separated by a web 27 . Will be more than two If different media are conveyed through the riser, the housing 20 can also have more than two chambers 6 .

In addition to the round cross-section of the housing shown, it can also be square or polygonal, with the chambers also being able to have different cross-sectional shapes.

5 and 6 show a corresponding floor distributor 4 for only one medium, e.g. hot water, with four riser pipes 2 being arranged on a circle of holes. Of course, fewer or more than four tubes can also be arranged for one medium.

The housing 20 in this case has only one chamber 6 , with a branch piece 8 being arranged eccentrically on the central housing part 22 . The housing part 22 is provided with an indentation 28 . For two different media, two floor distributors can be arranged next to one another, with the eccentric arrangement of the connecting piece 8 bringing it to rest in the indentation 28 of the adjacent floor distributor.

As can be seen from FIG. 6, the housing in this embodiment variant has a square cross section, with the connections for the risers only being able to be rotated by 90° relative to one another.

7 and 8 show an embodiment variant of the floor distributor shown in FIGS. 3 and 4, only the middle housing part 22 being different here.

OMPI

-fo . WIPO is designed differently. The housing part 22 consists of connecting pieces 30 provided with flanges 24, between which two intermediate pipes 31a and 31b are fixedly arranged. These intermediate tubes 31a, 31b form part of the chambers 6a and 6b. The two branch pieces 8a, 8b are arranged offset from one another on these pipes, as a result of which there is sufficient distance for the attachment of shut-off valves.

9 and 10 show an embodiment variant of the floor distributor for a medium shown in FIGS. 5 and 6, the central housing part 22 here consisting of two connecting pieces 30 and an eccentrically arranged intermediate pipe 31 to which the branch piece 8 is attached.

One of the riser pipes 2 is connected directly to the further riser pipe 2 by a piece of pipe 14 and thus forms the circulation line. Of course, such a piece of pipe can also be used in the embodiments according to FIGS. 3 to 8 for one or both media.

For two different media, two tiers are arranged side by side, with the eccentric arrangement of the intermediate pipe 31 allowing the branch pieces 8 to be arranged side by side as shown in FIG.

Since in the embodiments according to FIGS. 9 and 10 the housing parts 21 and 23 can be connected to the middle housing part 22 in any circumferential position, the most favorable position for the branch piece 8 and the connections for the risers 2 can be set, so that a desired helical course of the risers can also be set.

The floor distributors 4 can be fastened by brackets which are connected to the central housing part 23 or the intermediate pipes 31, 31a, 31b or the branch pieces 8, 8a, 8b.

A particularly advantageous type of attachment is shown in FIGS. 5, 6 and 9, 10, with one half of the two shell couplings 25 being attached to a retaining plate 29 at a predetermined distance. The floor distributor is then attached to a building wall by means of the retaining plate 29 .

11 and 12 show a simplified embodiment of a floor distributor 4 with a two-part housing 20 whose parting line 19 runs transversely to the riser axis 3 . The two housing parts 21 and 23 are identical in shape, with only the seal 26 being arranged in one, preferably in the lower, housing part 23 .

The embodiment variant is provided for two different media with one chamber 6a and 6b for each medium, which extends symmetrically over both housing parts 21, 23. Each housing part 21, 23 has a branch piece 8a, 8b which is connected to either chamber 6a or chamber 6b. The two housing parts have at the parting line 19 flanges 24 which connect the two housing parts by means of the two-part shell coupling 25, which can be connected by means of screws 32. A retaining plate 29 for fastening the floor distributor to a building wall is arranged on one half of the shell coupling 25 . The riser pipes 2a and 2b are connected to the two housing parts 21 and 23 by means of detachable connections 7 or non-detachable connections 17 as shown in FIG. 3, with more than four riser pipes being able to be connected to each housing part. The housing parts 21, 23 are circular in cross section and the chambers 6a and 6b are approximately semicircular in cross section.

Thus, no great heat transfer between the chamber 6a for cold water and the chamber 6b for hot water

«, an insulating layer 33 can be arranged in the web 27 between the chambers. There is also the possibility of separating the two housing parts 21, 23 again along the riser axis and arranging insulating material in the parting line or providing an air gap.

Of course, _further variants of floor distributors for one or more media are possible, with the riser pipes being circular,

- i.e. the pipe connections lie on a circle of holes - are arranged and advantageously run helically in the longitudinal direction.

If the distances between the floor distributors 4 are greater, the riser pipes 2a, 2b are advantageously routed again in between, as can be seen from FIGS. 13 to 16.

Oh PI The riser 1 shown in FIGS. 13 and 14 consists of six circularly arranged pipes 2a, 2b, ^* which are guided or held firmly in one or more spaced-apart brackets 40 and run helically in the longitudinal direction. The holding stanchions 40 are designed as round discs 41, which have several circular exceptions 42 on the circumference for receiving the pipes 2a, 2b. The discs 41 have a central bore 50 and can therefore be pushed onto a longitudinal support 34 designed as a tube 12 or rod. The longitudinal beam 34 is fastened to a building wall by means of wall clamps 51 . All or only some of the discs 41 arranged on the longitudinal member 34 are clamped firmly to the tube 12 by means of an adjusting screw 43 .

Preferably, at least one disc 41 is arranged loosely on the pipe 12 between two firmly clamped discs 41 or between two floor risers 4, so that it is held by the pipes 2a, 2b but can be rotated and displaced on the pipe 12. If only one disk 41 is to be rotated, this can be arranged on the tube 12 between two adjusting rings provided with adjusting screws. The discs can be clamped to the pipe 12 in such a way that the helix angle of the riser 1 can be adjusted to suit the operating conditions. A uniform change in the pitch angle as a result of changes in the length of the pipes when the temperature changes is easily possible thanks to the displaceable and/or rotatable discs 41 . Change the tubes 2a, 2b differently in length, so can

OMPI y _Λ these additionally bend or stretch.

15 and 16 a further variant of the embodiment of the holders 40 and the longitudinal member 34 is shown.

The longitudinal beam 34 consists of a profile bar 44 preferably having a T-slot cross-section, on which by means of a T-slot block 52 and a clamping nut 53, holding supports 45 can be attached in the longitudinal direction at any point can be clamped. The disks 41 can be clamped on the holding support 45 either with a centrally arranged screw 46 or can be slipped onto a pin 47 arranged on the holding support 45 . (see FIG. 15 below), whereby the disc 41 is then also rotatably and axially displaceably guided in a bore 48. It can be seen from FIG. 14 that the circular recess 42 has an abutment for the tube 2a or 2b of slightly more than 180 and a circumferential opening 54 of slightly less than 180. This enables the pipes 2a, 2b to be pressed into the recesses 42 from the outside, while at the same time they are prevented from jumping out. To secure or clamp the pipes 2a, 2b to the disks 41, a clamping band 49 can also be arranged on the circumference of the disk 41.

If, in an arrangement of cold and warm water pipes 2a, 2b, there is a different change in length between these pipes, the preferably movably arranged disks 41 are advantageously

^REΛ OMPI designed in parts, with a part of the disk being used for guidance for each of the differently expanding tube groups. The disc can be segmented or divided in a plane perpendicular to the longitudinal axis of the tubes 2a, 2b.

The risers are preferably made of a plastic such as polypropylene, polyethylene, polybutene, polyvinylidene fluoride, or cross-linked polyethylene.

Flexible metal tubing made from mild steel, light gauge stainless steel, or copper can also be used.

The floor distributors can be made of iron, non-ferrous or light metals or of plastic, whereby the plastics listed for the pipes can also be used, for example.
