METHOD FOR INSTALLING HOT WATER AND / OR WATER HEATING PIPES IN A BUILDING AND A CONNECTION AND DISTRIBUTION UNIT FOR IMPLEMENTING THE METHOD

The invention relates to a method for installing domestic water and / or water heating pipelines in a building, in which the supply and return main water pipes are connected to branch pieces, which are further connected to the operating points of the plastic pressurized water pipes using protective pipes. The invention also relates to a switching and distribution unit for carrying out the method.

According to the prior art, the installation of domestic hot water and water heating pipes in a building has taken place in several stages. The frame pipes are typically routed along a wall along the entire length of the building, and branch pipes are routed down from these frame pipes, for example to the lowered ceiling of wind cabinets, in which the branch pieces are placed. In this space, protective pipes have been laid from the operating points and plastic pressurized water pipes have been installed in these protective pipes, which are finally connected to the branch pieces. 20 The distribution group is built of separate components at the workplace at each site separately. Due to this method of installation, the construction of the pipelines has had to wait at a different stage for the completion of other construction work. In certain locations, some sort of housing may be constructed in which distribution, shut-off, and measurement components are mounted on the protruding tubes 25.

According to current building regulations, plastic pressurized water pipes must be installed in protective pipes so that they can be replaced if necessary. The use of plastic pressurized water pipes, on the other hand, is quite practical due to the quick installation work.

The object of the present invention is to provide a novel method for installing pipelines, which would enable a considerable rationalization of the installation work. In order to implement the method, a new piping connection and distribution unit has also been created. The characteristic features of the method according to the invention are set out in appended claim 1 and the features of the connection and distribution unit for carrying out the method are set out in claim 3. The method according to the invention requires a pre-40 enclosed unit comprising all connectors firmly connected to the housing 2 91791. immediately a point of attachment and there is no need to build a distribution group on them. Other embodiments and advantages of the invention will become apparent in connection with the following embodiment.

The system according to the invention requires that, already at the planning stage, space be reserved in each apartment for the connection and distribution unit. The space below the floor of the wind cabinet is often particularly suitable for such a space. The plumbing work can then often be done almost once. In the foundation phase of the buildings, the insulation element ducts 3 are already installed below the plinth, and at their ends a connection and distribution unit 2 for bringing or removing piping to each building is installed. Other distribution units 1 are installed during the construction of the pipeline.

30 With regard to the heating system, the invention is best suited for the so-called ·. using a single-pipe system in which several radiators are connected in series to the same heating loop.

35 The plumbing work in each apartment is carried out at the same time, in which case the main water pipes from the previous 4 units to the distribution unit in question are first laid using protective pipes and then the pressurized water pipes can be laid using protective pipes to the applications. After 3,91791, when the main water pipes are routed to the next apartment, the floor and wall structures can be completed. Both the body and the distribution pipes can remain inside the casting in their protective pipes. It is possible to change the pipes afterwards. In the arrangement 5 of Figure 1, the distribution unit 2 provided with a well is located in the heating center 5 and on the floor of the wind cabinet of the end apartments of the two buildings.

Figure 2 shows the most common type of first floor apartment-specific switching and distribution unit 1. This unit 10 also includes apartment-specific water volume measuring devices. The housing 6 is made of fiberglass and includes a cover 7 on a collar 14, which forms part of the floor of the wind cabinet and can withstand walking on it. The body water pipes 15 are introduced into the distribution box by means of a protective pipe 16 extending about 20 mm inside the housing 6. 15

The body water pipes 15 are connected to T-pieces 9, which are fixed to the bottom of the housing 6 by means of a fastener 8. The bracket 8 securely ties the T-piece 9 to the housing, on which it still relies a shut-off valve 10 with an angle piece, a water-20 flow meter 11 and branch pieces 12. The main water line continues from the other side of the T-piece 9 with a similar main water pipe 15 and further using a protective pipe 16. Figure 2 shows the cold domestic hot water (DHW) main water line and its branching components at the front.

Fig. 3 shows the complete piping of the unit of Fig. 2, in which the heating trunk lines are marked with LP and LM and the hot water supply line with LV. The branches of the heating water lines are indicated by reference numeral 13. Figure 3 shows that the branch 30 of the hot water hot water has a total of five units and the hot water branch 12 has three units, respectively. Plastic hot water pipes are marked with reference number 20 and their protective pipes with reference number 19. Heating pressurized water pipes are marked with reference number 22 and their protective pipes with reference number 35. In this case, unit 1 is connected to two heating loops implemented as a single pipe system by means of branch pieces 13. As such, the other lines are constructed in a manner similar to the cold domestic water line, i.e. the components of each line are tied to the housing by means of a T-piece. This provides a clear anchor for the pipes to be connected, even though the construction work may otherwise be quite unfinished.

5 In apartment buildings, a slightly different solution is needed on the upper floors. In this case, the distribution unit 23 according to Fig. 4 is placed in a vertical flue, in which air conditioning and drainage pipes are typically also placed. Thus, the trunk lines are routed to the top floor in this vertical flue and in each room through a unit similar to that explained above, but in this vertical direction. Here again, in a similar manner, the bottom of the housing 6 comprises fasteners 8 with which the T-pieces 9 are tied. These further bind the assembly formed by the shut-off valve 10, the flow meter 11 and the branch pieces 12 to the housing. In this case, intermediate pipes 17 have also been used between the branch pieces 12 and the water flow meters 11. In this case too, the branch pieces 12 are in a different plane than the main water pipes, although the outlet direction of the domestic water pipes is parallel to the main water lines.

20

According to the invention, the connection and distribution unit is used to install the main water pipes on a different level than the pipes leaving the branch pieces, which makes the system very clear.

The distribution unit 2 with a well shown in Fig. 1 is shown in more detail in Figs. 5 and 6. As such, the distribution unit at the top is similar to the distribution units in Figs. Below this, a well part 24 is placed, at the bottom of which an insulating element channel 19 is introduced. Through this, the plastic frame pipes 30 20 are passed from one building to another and connected to the corresponding units. Here again, a cover 7 is provided on top of the distribution unit, which correspondingly forms part of the floor. For the insulating element channel, a hole is formed near the bottom of the well part 24, for which the well part includes breaking edges 18 on each side, whereby the hole 35 is formed according to the inlet direction.
