Procedure for laying services, drainage and other main lines through recesses in the ceilings of a building lying vertically one above the other "

A few years ago there were thoughts about the construction of apartments according to a completely new principle has been developed. This principle goes towards a load-bearing construction with a relatively high durability build, in which the actual apartment by means of a fake of normal elements manufactured in the workshop can be shaped according to the wishes of the user.

On the basis of this principle is of the

Applicant developed a so-called installation package, consisting of normal wall and furnishing elements, from which apartments with different division and lining in one scaffold-like girders erected from concrete are formed can.

Based on simple agreements, normal supporting structures or scaffolding can be used according to this construction principle can be completely processed in order to complete it by means of simple assembly work with the help of normalized elements finished apartments with different layouts and To represent the appearance. The traditional intertwining of "shell" and "prefabricated" and the many with it Associated work to be performed depending on the circumstances on site is therefore largely in Failure has come. A more uniform and therefore more rational construction, which is still suitable for the user offers many more possibilities in relation to the furnishing of his home that he wants.

409884/0417

One problem that has not yet been resolved is the

Connection between the "house lines" belonging to the installation package, namely the provisions for gas, water, electricity, ventilation that P.T.T. and the like. and the "Services" to be accommodated in the supporting structure. In the up to now ■ according to the principle described above The services, drainage and ventilation lines are located centrally across from the built apartments to be formed apartment selected location arranged in such a way that at a more or less centrally located Place the branches that can be made to the house lines going out from this point. The relocation of the However, services are still carried out according to the conventional system, which is based on the fact that in the supporting structure Recesses are provided through which the various lines are differentiated from the Installers are laid, after which the remaining recess cross-section is sealed with in-situ concrete. this means a major installation work on the construction site, which is actually the thought on which the here considered new construction is repugnant. This Conventional installation work is inherent in the sound obstacle that usually strives to an inadmissible height which vibrations excited by lines installed in this way during use caused.

The invention now aims at the last-mentioned imperfections of the supporting structure installation package principle to be countered by developing a compilation of service, drainage and other main lines, which at the construction site only requires simple normal assembly operations instead of the conventional ones, usually more varied by specialists Technical areas to be carried out, boring and often complicated installation work.

409884/04 1 7

The invention proposes a method for laying service lines, drainage and other main lines due to recesses lying vertically one above the other in the ceilings of a building, more particularly one Residential building of the supporting structure installation package type, which method is mainly characterized in that for each floor a part of the service lines and the drainage and other main lines in the form of one parallel, compact bundle attached to a common carrier, with the line point at one end this carrier can protrude, the carrier on it in such a way between the ceilings, which the floor in question limit, so that the wearer puts his foot on the edge of the recess in the lower, sound-insulating Ceiling comes to rest and comes to rest with its upper end at a distance from the underside of the upper ceiling, while the protruding conduction sheaths extend through the recess in the top blanket, after which the remaining recess cross-section around the protruding line end with one in the longitudinal direction Fills the sealing block slidably seated on the cable bundle.

This way of installing services and other main lines suggests that one of the Number of floors corresponding number of units, in which parts of all desired service and main lines are united in a bundle, are, as it were, stacked on top of one another.

Bundling the various parts of the line to form a floor-height unit is particularly suitable for workshop execution, so that the work to be performed on the construction site is only related to the implementation Simple assembly work comes, including the coupling of the line parts of the stacked units.

409884/0417

In using the inventive
Process achieved compact line package are the
separate lines on each floor above the relevant
Beam supported on the floor of the floor in question. This not only means a good distribution of the total weight of the pipe package over the various floors, but also offers the possibility of using couplings of various types, such as flexible couplings in particular, where it concerns the connection between parts of drain pipes, gas pipes and such pipes. Such flexible couplings then need because
the support of the lines in parts is not difficult
Absorb stresses and then only need theirs
Exercise sealing connection function.

The various line parts are preferably in accordance with a predominantly rectangular elevation pattern
set up in such a way that the (sewer) drain line (s) are located as a shielding wall between the electrical lines provided on both sides of the same on the one hand and the water and gas lines on the other. In this way the electrical lines (PTT,
possible lines of a central antenna system, electricity cables, lines for house telephones and the like.) against
leaking and splashing water pipes protected.

If there is a ventilation line or duct in the line package, it is advisable to attach it to the
to be provided in a rectangle on the side of the water and gas pipes facing away from the drain pipe (s).

A practical implementation of the common carrier is characterized by a profile with a main C-shaped cross-section, the flanges of which are provided with suspension means for the various parts of the pipe.

409884 / CU1 7

A special feature of the profiled in this way, e.g. realized by bending from sheet metal The carrier is that in one of the flanges of the C-profile one extends in the longitudinal direction of that flange extending recess is provided in which the Elektrizxtatslextung or the pipe is housed for it, while the other electrical lines on both sides to the Outer side walls of this recess are provided and the drain lineCen) against the back of this recess are attached. In this way one gets a construction in which the electricity line is opposite to the rest electrical lines (P.T.T., line of the central Antenna system, house phone line and the like.) Is shielded, while at the same time a suitable mounting base for the drain line (s) is obtained.

According to a further feature of this design, the gas and water pipes are against the inside of the other flange attached, while the ventilation duct or the ventilation shaft on the outside of that Flange is provided, with the interposition of a fire-fighting layer. For the ventilation duct or shaft is thus also, in a simple and expedient manner, the fire protection arrangements set up for such lines enough. As a result, the ventilation shaft mediated by a fire-fighting layer to the Outside of the second flange of the C-profile is attached, is the cross-section claimed by the line total actually divided into two compartments, of which only the compartment containing the ventilation duct den Fire protection requirements that apply specifically to the ventilation shaft needs to suffice. In this connection it is noted that the shaft-like unit of carrier and Lines finally completely different from the general fire protection arrangements Sufficient elements of the above installation kit is disguised.

In Fig. 1 and 2 with 1 are provided in the ceilings 2, vertically one above the other recesses denotes through which the vertical line package according to "the invention is to be provided. The The difference between FIGS. 1 and 2 is that in the situation according to FIG. 1, the recesses are each surrounded by a horizontal floor surface are surrounded, while in the situation according to FIG. 2, the recesses are part of their Perimeter are limited by vertical walls and are therefore only partially surrounded by a horizontal floor surface. This difference in the position of the recesses can be important in relation to the support of the line part carrier, as will appear below.

In the schematic bundling pattern according to FIG. 3 3 designates the ventilation line, which according to the usual standards has a diameter of the order of magnitude of 22 cm and thus at the same time forms the widest of all the lines discussed here. The diameter of the tube 3 wound from sheet metal, for example, is therefore decisive for the dimensions of the short rectangular side of the rectangular one Bundling pattern.

With 4 is the common sewer and Drainage water pipe called, which e.g. consists of asbestos cement (Eternit) and a diameter of 10 to Cm- has. In the space between lines 3 and 4 are the Lines 5, 6 and 7 set up for the flowing consumables gas and water. Set lines 5 and 6 e.g. those for hot and cold water, while the gas line is designated. At the line 3 remote short side of the rectangle, namely on the side of the drain line facing away from the lines 5, 6 and 7 4 are the various electrical lines, such as the electricity line 8, the P.T.T. line 9 and the lines 10 for the house phone and the connection to the

409884/0417

central antenna system. As from the bundling pattern shown the electrical lines 8, 9 and 10 can be seen from the drain line 1 opposite the "wet" lines 5, 6 and 7 shielded. The distances between the lines or line groups are also such that the Lines are separately accessible from the directions indicated by the arrows. The arrows also indicate the Main direction for the branches of the main lines drawn to the various house lines (not shown) at.

Lines 5-10 are at the beginning of the description, as well as in the claims, with the collective word "service lines" denotes, by which it is meant that this is that part of the various supply lines, which is usually under the management of the various public utilities (water, gas, electricity, P.T.T.) falls. Strictly speaking, this expression only applies to Lines which by means of a special device such as a (water, gas, electricity) knife from the to the apartment the same associated supply lines are disconnected.

On the basis of the bundling pattern according to FIG. 3 is the carrier 11 for the line parts to be bundled in the preferred embodiment according to Fig. 4- in the form of a mainly C-shaped profile, which can be easily bent from sheet metal. The ventilation duct part 3 is below Mediation of a fire-fighting layer 12, e.g. made of glass or rock wool, by means of self-tapping screws or on other way attached to the outside of the slightly concave curved flange 13, while the water and Gas lines 5, 6 and 7 are suspended on the inside of the same flange by means of saddles 14, which saddles in Fig. 5 are shown in detail. The saddles 1M- which in relation are made of a suitable plastic, e.g. polypropylene, on a vibration-damping attachment,

409884/0417

are provided with somewhat resilient clamping arms 14a, so that the line in question 5-10 "snaps" into their Rest point can be pressed. The vibration-damping one The effect and the fixed position of the line is achieved by the interposition of a filling 15 made of rubber-like material (e.g. neoprene) increases which filling e.g. by shifting in axial direction over the one to be fastened Line in their place .between the clamping arms 14a and the Line can be inserted. The saddles 14 are provided with a constriction or neck 14b, in which (s) the edges of the fastening holes 16 recessed in the relevant flange of the carrier can engage. These Holes 16 are preferably of the keyhole type and therefore consist of another part and one narrower part, all this in such a way that the saddle with its constriction after being pushed into the further part or neck 14b between the edges of the narrower part of the Mounting hole 16 can be pushed.

In the flange 17 of the support profile .11 is a In the longitudinal direction of that flange there is a recess 18 which serves as a latching point for the electricity line 8, which is thus separated from the outside of it Leads 9 and 10 located in the recess is shielded. Lines 8, 9 and 10 can be used in a similar manner as for the water and gas lines 5-7 indicated, to the in the Nearby parts of the flange 17 can be attached. The recess 18 also provides a suitable suspension support obtained for the drain line 4. The drain pipe 4 is in the manner shown in more detail in FIG. 8 against the rear side of the recess 18 by means of a clamping band 19 attached, with the interposition of a vibration-damping rubber layer 20. The clamping band 19 could thereby be inserted by recessed slot holes in the side walls of the recess 18.

409884/0417

Because of the C-shape of the support profile in particular the water and gas pipes 5-7 to the branching work to be carried out carefully according to the arrows shown in the bundling pattern according to FIG. 3 amply accessible. In addition, all the desired recesses could be provided in the flange 17, which for the Accessibility of the electrical lines 9 and 10 are necessary. In the web of the C-shaped support profile could further recesses may be provided, e.g. a recess for one directed to the left (as seen in Fig. 4-) Branch of the drain line M-.

In Fig. 4- is shown with three broken lines like the support-conduit assembly at least on three sides along elements of the above Installation package will be disguised, which elements of course the necessary recesses should have for the passage of the line parts conventional branch lines. the The fourth side of the line package, shown with a dash-dotted line, could either be from a wall of the supporting structure (in the situation according to Fig. 2), or also be limited by an Eliment of the installation package.

In Fig. 6 "is a side view of the support profile 11 shown with the attached line parts, seen on the closed side of the C and that on the Place between a lower and an upper ceiling 2 of a floor. The height h of the support profile 11 is some Cm smaller than the (smallest occurring) standardized room height H. The line parts 3-10 protrude at their upper ends so far above the carrier profile 11 that the with their upper ends come to lie above the surface of the upper ceiling 2. The different dimensions are further chosen so that the carrier profile'11 with the attached line parts 3-10 from the with

9884/0417

broken lines shown oblique position can be put in its place. The support profile 11 comes to rest on both sides of the recess 18 parts of the flange 13 on the base 1a of the recess in the lower ceiling 2 . The assembly of the support profile line parts is thus supported eccentrically, with the result that this assembly has the tendency to tilt with its upper end to the left. Against this tilting movement, the line package is supported by means of a filling block 21 adapted to the dimensions of the recess 1 in the upper ceiling 2, which block, provided with the desired line holes, is slidable in the longitudinal direction on the protruding sides of the line parts and, after the line package has been laid, in its Place is pushed within the relevant recess. This full block 21 should, in connection with the desired sound insulation, consist at least partially of sound-insulating material.

The contact between the base of the support profile 11 and the lower ceiling 2 at the point of the above-mentioned support point should also have a sound-absorbing character be. For this purpose, the lower edges of the flange 13 are bordered on both sides of the recess 18 by a rubber profile 22 namely with the mediation of an edge thickening profile 23 protecting this rubber profile against splitting (see Fig. 7).

Because of the above-described support of the carrier profile 11 and the way in which the various line parts are fastened, the carrier-line package as a whole forms a mass-spring system, within which the lines causing the vibrations again form small mass-spring systems. In this way, the vibrations are optimally dampened. _v

A carrier profile with associated line parts, which was put in place in the manner described above and occupies a storey, could be extended further to the lower or upper storey by arranging further support profiles with line parts in the same way. The coupling of the line parts belonging to the adjoining support profiles forms an important aspect of the method according to the invention. In principle, it would be possible to use socket connections of the usual type by inserting this carrier profile with its protruding ends of the line parts through the relevant recess in the upper ceiling and then with the lower ends when laying a next support profile with line parts lower the pipe parts into the sleeve inserted on the upper ends of the pipe parts of the already laid support profile below. Such a way of working would, however, require a great deal of freedom of movement and, in addition, excessively large recesses. On the other hand, where the unavoidable need to bridge vertical tolerances in relation to floor height and ceiling thickness has to be taken into account, it is advisable to use couplings of a sliding type. As far as the coupling of the parts of the drainage pipe and the ventilation pipe is concerned, a rubber coupling sleeve, as indicated at 24 in FIG. 9, or an inner sliding connector, as indicated at 25 in FIGS. 12A, B, could be used. In Fig. 12A with 3 'the upper end of the ventilation part of a lower, already laid in its place support profile is shown, while 3 "denotes the lower end of the corresponding ventilation line part of the next higher support profile that has just been put in place Connection between the ends 3 ¹ and 3 "of the line parts serving sliding connector 25 is still in the maximally pushed-in position within the end 3"

409884/041 7

of the line part, in which position the sliding connector e.g. by means of a self-tapping screw 26 of the sheet metal screw type is secured. After removing the locking screw 26 you can slide the connector Lower into end 1 of the line part until the shoulder edge 25a rests on the upper edge of the end 3 'of the line part. The sliding connector could continue if desired to be fixed in its effective connection position by means of self-tapping screws or in some other way, while the exposed securing hole for the securing screw 26 can be sealed.

The conventional double connecting sleeve with an inner stop shoulder is not suitable for water pipes. Instead, it is advisable to use the connecting element 27 shown in FIG. 10, which is designed as a so-called wedge 27a at one end and as a sleeve 27b at the other end. This connecting piece should have a length at least on one side (ie either on the wedge side or the socket side) which corresponds to the overlap length necessary for a good connection, increased with the tolerance and / or assembly space to be bridged this connection piece with the socket end 27b turned downwards, so that the upper end 5 'or 6 ^{f of} the water pipe part of each support profile can be designed as a wedge, that is, straight, while the lower end 5 "or 6" of the water pipe part of the When the next higher carrier profile is laid, the connecting piece 27 can then only be inserted up to the maximum insertion depth into the lower socket end 5 " Sleeve end 27b to be pushed onto the upper wedge end 5 ^{1 of} the underlying water pipe part. This type of coupling also offers the possibility of using prefabricated rings 28 made of hard solder, which when heated by capillary action in the spaces between the

409884/0417

Sockets and wedge ends flow out.

To couple the upper or lower end or 7 "of adjacent gas line parts, a known type of sliding flexible coupling can be used, as shown in FIG. This clutch, which consists of a coupling piece 29 provided at both ends with an external thread with screw nipples 30 and rubber sealing rings 31, can be converted into one, the laying of a support profile non-hindering position on one end of the line parts to be coupled to see if that relevant carrier profile is brought into place, to be brought into the correct connection position and through Tightening the nipple 30 to be fixed.

As far as the coupling between the drainage line parts 4 is concerned, it has already been noted above that this coupling can take place simply by means of a rubber sleeve 24 (see FIG Line part) can be connected and from which the other end can be temporarily (knocked back) (see the situation on the right in Fig. 9) to remove obstacles when laying the relevant support profile. In the left half of Fig. The coupling between the lower and the upper ends 4 ¹ and 4 "of the two line parts 4 shown in their effective position. From FIG. 9 it can also be seen that the two line parts 4 include branch pieces, in this case T-pieces. The lower end 4 ″ of the overhead line part 4 in FIG. 9 is formed by a T-piece 32, the branch 33 of which is intended to be connected via the open side of the C-profile to the sewerage line belonging to the floor in question.

409884/0417

Furthermore, the upper end ¹ + 'of the drainage line part 4 below is formed by the wedge end of a T-piece 34, the branch 3 5 of which is intended to provide a connection to a waste water drainage line 37 using a transition sleeve 36. "

In a similar way as just now with regard to the

Drain line parts 4 has been described, can be different Types of branch pieces belong to the water and gas lines 5-7.

With regard to the electrical lines 8-10, it should also be noted that this is actually about jacket pipes acts through which the relevant electrical conductors are later pulled. The parts of these jacket pipes can be connected to one another in various ways, e.g. with clamping sleeves made of sheet metal or other coupling pieces will.

The sealing plate 21 * shown in FIG. 13 is intended as an alternative to the one used according to FIG. 6 Filling block 21 to serve. This sealing plate will not be like the. Filling block 21, between the upstanding edges of the Recess 1 included in the relevant ceiling 2, but comes to rest on the ceiling 2, which is why the Dimensions of this plate are chosen so that di.e edge parts of the same cover those of the recess 1. the Sealing plate serves not only as a seal between the two sides above and below the relevant Ceiling 2 lying rooms, but also functions as a support for the carrier profile 11. The sealing plate is made laminated and consists in particular of an upper layer 40, e.g. made of sheet metal or another suitable stable material, an intermediate layer made of rubber or such an elastic material, and a lower layer 41 made of asbestos or one

40988A / 0417

-Jrf-

such fire-resistant material. The sealing plate is according to the pattern shown in Fig. 3 with continuous Provide openings for the various lines. The diameters of these through holes are 3a and 3b, respectively in the upper and lower layers 40 and 41 respectively selected a little larger than those of the lines in question, while the diameters of the corresponding through holes 3c in the elastic intermediate layer 42 are a little smaller than those of the relevant lines are selected. This ensures that the edge parts around the continuous openings tight around the elastic intermediate layer and therefore medium-tight around the various lines come to sit eagerly. At the same time, the elastic intermediate layer 42 acts as a vibration-damping one Element, so that vibrations occurring in the lines are not transmitted to the ceiling 2 via the sealing plate 21 ' will. The rubber profile "22 used for the same purpose in FIG. 6 can therefore be omitted. The lower Layer 41 of the sealing plate finally ensures the prescribed fire rejection.
