Description

The invention relates to a piping installation element, mainly for the renovation of pipelines. It is known from the prior art, in particular, the pipe modules used in connection with renovations and renewal of pipelines, which are installed on the wall surfaces at the renovation site without dismantling the old one. Pipes as well as electrical and / or data cables and wires are routed inside the module.

Installation is quick and time is saved from renovations compared to traditional methods, where the resident has, in the worst case, had to move out of their apartment for several weeks.

The water pipes are routed in their own shaft compartment and the data / telecommunication or electrical cables / wires in their own compartment within the module. In the event of a fire, when the pipes and cables are insulated from the outside, they remain intact and usable inside the module.

The thermal insulation used and the fire-retardant mass act not only as thermal insulation but also as fire insulation. When using gypsum board, the fasteners for water or similar pipes are anchored to the base plate of a sheet metal housing. For a rivet nut, a generally inwardly extending space for this rivet nut is punched into the sheet metal. A space corresponding to this stamped hole has to be machined on the gypsum board, which is quite laborious.

The inconvenience when using modules is the lack of space in corridor spaces, for example. The object of the invention is to provide a more practical and simpler solution than before for the production of a fire-protected installation element. © I Even a small reduction in construction height is a decisive advantage. In addition, O. . . lee as a O insulation does not need a separate space for stamping. The hole can be drilled through E insulation and thin sheet metal and a rivet nut can be installed through the insulation (heavy with kiwi). 8 Achieving, for example, a lower construction height of 15 mm for the L1 module is a great advantage over old structures.

This application therefore discloses the structure of a tubular module in which the structural height L1 of the module is reduced. the characteristic features of the invention are set out in claim 1.

The module is preferably implemented in such a way that a fire-retardant compound such as gypsum board is not used on the fastening wall of the element, but is replaced by fire wool coming directly against the outer shell, i.e. the housing body, and fastened to it by gluing.

Its insulation properties are significantly higher than normal fire insulation wool. The so-called heavy wool, specific gravity 140 kg / m.

In this case, it is also easier to attach the stands to the outer shell of the element. The fastening rods of the pipe clamps can be inserted into the threads of the rivet nut without having to make holes or charges in the gypsum, as would be the case, for example, when using gypsum.

This makes it easier to install the pipes in the mounting element.

Fire insulation layers, which can be gypsum board, surround the pipes and their wool insulation inside the structure as well as the cable / electrical conductor space so that the wires / data cables remain well insulated even in the event of a fire. There is a layer of fire wool outside the firestop compound and the outer installation element has an outer shell housing body, which can be, for example, a metal plate.

The pipe or pipes are placed in the grooves of the fire wool insulation. The fire wool insulation comprises a semicircular groove in the wool layer below and, correspondingly, a semicircular groove in the upper wool layer. The tubes are placed in the groove and their holder and supported through the rod in the thread of the rivet nut o 25. In connection with the pipe fixing arc, there is a nut in which the rod is O fixed and by turning the pipe fixing arc, the fixing rod db rotates in the thread of the rivet nut and is obtained by turning it to the correct height position and

No good attachment. The pipe mounting arches are screwed together.

O I The hole is drilled through the insulation layer and the module outer shell plate. The rivet nut N 30 is inserted into the hole and the punching hole in the lower surface. The end S of the rivet nut is pressed against the edges of the hole with a tool.

In the structure according to the invention, the joints of the wool layers are at different points 5 adjacent to the wool layer. In this case, no thermal joints are formed and the structure remains well insulated from inside the pipe installation element.

The piping installation element according to the invention is characterized by what is stated in the protection requirements. The invention will now be described with reference to some preferred embodiments of the accompanying drawings, to which, however, the invention is not intended to be exclusively limited.

The wool layers R17 (heavy wool) are bounded inside the shell 200 so that the wool layers R17 are located between the fire mass layer such as gypsum boards R20 and the shell 200 on the sides Y1, Y2 and the cover side Y3 of the element 100. The fire protection layer R20 such as gypsum board surrounds the pipe space 10 and the conduit space 20, however, so that in cross-section the pipe-side wall of the rectangular conduit space 20 is free of fire protection layer U10 such as gypsum layer and bounded by wool layer R14a and R14b. The pipe space 10 comprises at least one pipe 11 in pipe holders 12a, 12b supported by a rod 13 on a rivet bolt 14 in its threads. The rivet bolt 14 is passed through a hole in the metal plate of the outer shell 200 and is located in the recess of the base plate 200a of the shell 200 so that the base plate 200a can be supported against the mounting wall S of the element 100 and the rivet bolt does not rise from the washer plane. A hole f has been drilled in the wool layer R14a and the base for a rod 13 attached to the tube holder 12a and rotatable by turning the holder 12a into counter-threads of the rivet bolt 14 so that it can be secured to the shell 200 in the rivet 200 The second tube holder 12b is attached to the second holder 12a with a screw. The tube (s) are placed in the semicircular grooves 16a, 16b of the heavy wool layers R14a, R14b. Above the wool layer R14b, there is in the embodiment a light wool layer K80, i.e. “water wool”, the function of which is to act as a thermal insulator and fire protection and as a component enabling the pipes to be turned horizontally. K80 The heavy wool layer R14a is attached by gluing directly to the shell 200 to its o 25 sheet metal structure. For this reason, there is no O fire protection compound (gypsum board) against the washer 200a, but heavy wool 14a. 3 The wires / cables located in the guide space 20 next to the pipe space 10 are fastened to the mounting element 100 by means of cable clamps 17 passed through the wall plates. E The specific weight of the inner heavy wool (14a, 14b) is 140 kg / m 2, generally 130 to 9 160 kh / m ?. The outer heavy wool weighs 3 typically 170 kg / m ?. The specific weight of light wool (K80) is 60 -100 kg / m ?,

O S preferably 70 to 90 kg / m 2. > Figure 2 shows the installation element 100 of Figure 1 in the assembly step.

The shell damper 200 comprises 90 degree bends 18 and a rim 19. The dividing planes T1 and T2 between the element halves 100a and 100b will be located at different height positions than the dividing plane T3 between the wool halves R14a and R14b. In this case, no harmful thermal bridges are formed, from which heat and heat could penetrate inside the piping installation element 100 or escape from the installation element 100.

The structure thus acts as a thermal break structure.

3 shows a mounting element as seen from the direction of arrow 100 of Figure 1 from the direction K1.

The installation element 100 is thus a long and elongated structure when renewing pipelines and renovating houses.

It is attached from the shell 200 from its mounting surface 200a to the wall S of the building.

Fig. 4 shows an installation module 100 which exactly corresponds to the module of Figs. 1-3, but there is no additional wool layer K80 according to Figs. 1-3.

The embodiment of Figures 4-6 is particularly suitable for cases where the pipes do not need to be turned horizontally at the end of the module for vertical export.

The structural height L1 of the element 100 becomes small, which is advantageous, for example, in narrow corridor spaces.

L1 is in the range of 140 to 160 mm, preferably about 150 mm.

Figure 5 shows the mounting element halves 100a and 100b of Figure 4 separated from each other prior to assembly.

Figure 6 shows the mounting element 100 without the cover section, seen in the direction of arrow K2 in Figure 4.

Figure 7 shows a piping installation element 100 according to the invention, which does not comprise cable outlets or the like.

In Fig. 7, the piping mounting element 100 comprises a structure around a metallic outer shell S 25 200.

The shell 200a comes against the wall and N wool R14a is attached to it by gluing, preferably heavy wool.

The heavy plant consists of 3 halves R14a, R14b with pipe grooves 16a, 16b on both sides of the dividing surface T3 O for the pipes.

The wool layer R14a, R14b is surrounded on three sides I Y1, Y2, Y3 by fire protection mass layers U10, preferably gypsum, and between them and the shell 200 N 30 there are wool layers R17. According to the invention, the wool layer R14a is 2 heavy wool layers and is fixed with an adhesive to the housing 200 on its fixing surface S 200a, from which the element 100 is fixed to the wall S.

The structural height L1 N of the element is preferably in the range 140-180 mm.

By attaching the wool R14a directly to the shell 200 without using the flame retardant at that point, the structural height of the element 100 is saved. Element 100 is lowered relative to the prior art. This is advantageous in tight installations. In addition, the manufacturing technology is simplified. The piping installation element 100 thus comprises a fire and heat insulated pipe space 10 not a cable duct 20 in this embodiment.
