Abstract

The connection for the water and sewage pipes, on renovation of buildings, has a bridge holder channel (7,10) at the wall openings and/or across traffic zones within the building. They carry one or more carrier pipes under the floor levels, fitted into the existing concrete or prestressed concrete ceiling slabs. The longitudinal axis of these channels is parallel to the loose or tensed reinforcements in the concrete at the upper ceiling level. This longitudinal axis is on an alignment line with the tube bundle recess (1) with the layout of the channels in a prestressed concrete ceiling.

Description

The invention relates to an arrangement for connecting wet sections and / or Sanitary facilities with pipe shafts in the course of changes in the layout of the Conversion of existing type buildings, especially multi-storey ones Residential buildings in prefabricated construction.

Through modernization and reconstruction of multi-storey residential buildings in Panel construction can be achieved by maintaining a relatively low rent level Rentability of apartments in such buildings can be improved. It is a change to the existing floor plan is a measure to the future tenant what he wants and imagines To make an offer. In particular, the rearrangement of wet routes Kitchens, kitchenettes or cooking ranges and / or the sanitary facilities especially if they were originally windowless, one measure is which is welcomed by the potential tenants.

Problematic in changing the original floor plans and the Reorganization of wet lines and / or sanitary facilities is one of the Degree of possible construction freedom for a reorganization of pipe shafts, depending on whether at the time of reconstruction the storey overlying apartments are fully or partially inhabited, and on the other hand, the connection of the wet sections and / or sanitary facilities the pipe shafts usually present in such buildings for the Supply of hot and cold water, electrical energy and possibly gas and the Waste water disposal, since the original design is a direct one Provided connection.

To nonetheless from the constraint of the direct arrangement of wet sections and / or Sanitary facilities at the existing pipe shafts are to be exempted Drywall has long been building so-called stud walls the originally existing walls, with the  Connection lines between pipe shaft and wet sections and / or Sanitary facilities are arranged. In particular, the unpressurized Waste water pipe laid with the required slope.

According to DE 40 07 586 A1, for example, a comparatively large area is known Support plate in which pipes and / or lines can be integrated.

In DE 295 20 533 U1 and in DE 296 03 836 U1 a progressive Installation system for pre-wall mounting for the sanitary area described, which frame elements can be joined together to accommodate feed and Drain lines used and easy to use piping access allowed.

DD 278 372 also includes a component system for installation modules described, which for the reconstruction of sanitary room cells in Prefabricated buildings should be used with the help of pre-wall installation. This Component system consists of support elements, trusses, load transmission as well as cladding elements. It enables both new construction and modernization and reconstruction for various installation assemblies the training of storey-high installation shafts as well Installation recordings with a lower height, adapted to different functional solutions, and ensures easy accessibility of the Installation assemblies.

The interior construction system presented in DE 297 07 717 U1 for the renovation of Bathroom cells in type houses also use prefabricated system elements and curtain wall cladding elements. Doing so is pre-made Base frame-building shaft registers used, which also are placed one below the other and their vertical Pipe sections for the house installation connected to each other by sleeves become.

In DE-GM 90 06 512 U1, however, a solution is proposed, in spite of Subsequent use of an industrially prefabricated installation wall  Changes or extensions to building services systems, such as B. Pipe installations, easy to implement and therefore large individual on-site Possible variations are given. This is also achieved, among other things through the use of a manifold, which is in an open, is arranged approximately square recess and with a light Slope leads to a vertical downpipe. However, this is the intended one Recess in the floor or ceiling, which is usually made of concrete of a room already during the production of the corresponding element to provide. A subsequent change of the floor or the ceiling is not provided according to this solution, so that only to be built new industrially prefabricated type buildings an option for subsequent changes or extensions to building services systems.

A disadvantage of all known solutions is that the possibilities of Change in the floor plans with variable by means of pre-wall mounting installing, with the fixed existing or to be rearranged Manhole registers connected wet lines and / or sanitary facilities in existing type buildings, especially multi-storey residential buildings in Panel construction, are limited because a crossing of traffic areas, for. B. Corridors through which media carriers are not provided or not possible. In particular originally wet routes and / or Sanitary facilities can use the known modernization solutions and reconstruction not in the area of the windowed External walls are laid, since in most cases traffic areas, mainly in zones with door openings, the continuous use of the prevent known stud walls and due to the need for Ensuring disability-free traffic any disruptive constructive Design is excluded. There is also a rearrangement of storey-high, superimposed shaft registers with partial or complete continued use of the apartments in the renovation phase only in the rarely realizable.

The object of the invention is therefore, regardless of the degree of utilization type buildings to be redesigned an inexpensive, with simple means  Realizable arrangement ensuring the functionality of the installation for the variable installation of fixed shaft registers Wet lines and / or sanitary facilities, including well-known and to create tried and tested solutions and take advantage of them the installation modules of this type, which are also originally located internally, are variable without restrictions, especially in the area of windows provided outer walls can be installed, and thus the attractiveness renovation or reconstruction of typical buildings by an individual and to significantly increase the variable design of the individual floor plans.

This object is achieved according to the features of claim 1 by Arrangement for connecting wet sections and / or sanitary facilities with Pipe ducts and / or other ceiling openings in the course of Floor plan changes when converting existing type buildings under Use of conventional stud walls and / or other suitable ones Cladding to accommodate the predominantly horizontal, if necessary with the corresponding slope running inlet and outlet pipes, with in Area of wall openings and / or when crossing traffic areas recording channel bridging the respective area for one or more Media pipes and / or pipes for the supply of hot and cold water, Electrical energy and possibly gas and the disposal of waste water below of the floor level in the concrete or prestressed concrete slabs is arranged later and the longitudinal axis of this channel parallel to limp tensile reinforcement or the prestressed reinforcement in the upper Ceiling area runs, this longitudinal axis when arranging the channel in a prestressed concrete ceiling in a line of alignment with that in the element Pipe bundle recess lies.

So far, the prevailing opinion was that of the typified ceiling panels Housing construction, especially in those with tension reinforcement subsequent interventions in the structure endanger the stability of these components. That is why there were even simple holes for attaching light fixtures or ceiling decorations are generally not permitted. This on the entire ceiling related prejudice could be achieved through practical trials in the floor area and  intensive examination of the constructive and technological characteristics of the Prefabricated ceiling parts with regard to possible load reserves, with security bordering probability if structural and structural engineering are observed Basic rules do not endanger constructive stability become.

Another essential feature of the solution is that the longitudinal axis of the Channel parallel to the course of the slack tensile reinforcement or the prestressed Reinforcement is arranged in the upper ceiling area, making the aforementioned static and structural principles are followed, and the intervention in the Structure of the element can be made safely.

The main advantage here was that the prestressed concrete slabs unite area free of prestressing steel in extension of the original Have tube bundle recess.

The partial dismantling of a partition on the ceiling panel in the Area of the channel according to the features of claim 2 contributes to the preservation of required surface load-bearing capacity of the highly loaded interior ceiling despite the by interfering in the structure of this ceiling distorted transverse distribution of the Loads at.

An arrangement with a receiving channel is advantageous according to claim 3 depending on the media pipes to be laid up to approx. 10 cm wide and up to approx. 11 cm deep, but not deeper than 6 cm in the concrete ceiling, starting from the Floor level, what is trained to accommodate the Drainage pipe, but also of the media carriers usually available is sufficient and at the same time the need for material to fill the Gaps minimized. This can reduce the effort and cost of doing this be kept low.

As can be seen from the features of claim 4, the receiving channel filled with the media carriers with a hardening filler and with a  leveling, cast resin or filler layer adapted to the floor level closed.

It has been shown to be particularly advantageous that the filler used according to the feature of claim 5 consists of concrete screed, which for such Features required properties and at the same time easy to process and is profitable.

According to the features of claim 6, only that should be in the receiving channel Media pipe for the wastewater, which is connected to the downpipe of the existing pipe shaft is connected in the floor below.

The media feed to the new locations of the wet routes and / or Sanitary facilities take place according to the features of claim 7 strand-like over existing floors one above the other Ceiling breakthroughs in the area of the risers for the heating pre- and - rewind.

The latter embodiment according to claims 6 and 7 is particularly preferred, if there is free space on all floors above each other, there this is necessary for a speedy construction process. It enables that simultaneous renovation of several apartments, so that after completion of the Construction measures all apartments in the respective segment the improved Have residential properties.

The claim 8 relates to a method for changing the floor plan when remodeling existing type buildings using the arrangement according to one of the Claims 1 to 7, wherein wet sections and / or sanitary facilities with Pipe ducts and / or other ceiling openings are connected under Use of conventional stud walls and / or other suitable ones Cladding to accommodate the predominantly horizontal, if necessary with the corresponding downward inlet and outlet lines, and wherein of existing load-bearing walls and new room partitions to be rearranged one on one side of the window outer building wall area  limited space to accommodate the kitchen with dining area is formed, in which the Media lines for connecting the wet section with the horizontal supply and Waste disposal lines parallel to the walls with the help of suitable Fairings are arranged.

This makes it possible in industrial areas that were originally unsuitable for this manufactured type buildings meet a fully functional, higher demands to provide future kitchen with window and living function.

To enable access to the kitchen from the living area, according to Claim 9 in a space limiting the reception of the kitchen Room partition made a wall opening.

The configuration according to the feature according to claim is particularly advantageous 10, the space for receiving the kitchen with a retrofit Wall opening is provided in the area of the original load-bearing inner wall.

This will increase the living space of an apartment in one Bipeds at the expense of reducing the living space of the other apartment achieved, and thus both the need for appropriate housing for Satisfied individuals as well as comfortable spacious apartments.

With the features of claim 11, the joint laying of all Enables media lines between the wet section and the tube bundle recess, by draining the sewage pipe and the media pipes from the wet section the new room partition through the receiving channel for connection to the in the downpipe in the pipe bundle recess of the ceiling in the one below Storey as well as the vertical supply lines.

This type of execution is preferred with limitation and limitation of the Freedom of construction on a single apartment in an otherwise inhabited type building.

If there is space for the entire type construction, a conversion with the features of claim 12 particularly advantageous, in which the sewer line from the  Wet section along the new room partition through the receiving channel to Connection to the downpipe is carried out in the floor below while the connection of the media supply to the vertical supply lines in the There is a recess area for the risers for the heating flow and return.

This means that several superimposed apartments can be used at the same time with little effort and without major disability quickly according to the intended improvements are to be rebuilt.

Ultimately, it is also advantageous to use the features of the Claim 13, in which by means of new, provided with a wall opening, at right angles at a distance on the supporting inner wall separating the segments and a room next to the back of the sanitary cubicle is limited.

This adjoining room offers uses as a storage room, broom closet, Pantry, warehouse or the like and thus also contributes significantly Improved quality of living comfort.

The invention is illustrated below with the aid of exemplary embodiments Reference to the corresponding drawings explained in more detail. Here demonstrate:

Figure 1 is a floor plan of a multi-storey type building in prefabricated construction (two-in-hand) with internal installation modules (kitchen and bathroom) and marking of the traffic areas.

2 shows the same plan view of a multi-storey building type in bricks with solvent according verlagertem kitchen area including the associated Naßstrecke and new routing at magnification of the original living room of an apartment area.

Fig. 3 is the same plan view of a multi-storey building type in bricks with solvent according verlagertem kitchen area including the associated Naßstrecke and new wiring while maintaining the original living room area of both housing;

Fig. 4 shows the section AA from Fig. 3 of the crossing area in the prestressed concrete ceiling.

The conventional arrangement of wet sections 2 and sanitary facilities 3 in type buildings such. B. multi-storey residential buildings in panel construction is inside and thus windowless, as shown in Fig. 1. A change in the position in the window area is due to the change in the media line routing that is connected with it and the traffic area distribution 4 that opposes this, in particular with regard to the line routing required for the laying of the sewage line with a gradient and without impairing traffic above the floor level (risk of tripping) without any intervention in the floor structure and the underlying prefabricated parts or prestressed concrete ceilings not feasible.

Using conventional drywall partitions 6 , at the same time used as a "pretext" for receiving the predominantly horizontal, if necessary with the appropriate slope, running inlet and outlet lines is, as shown in Fig. 2, in the area of wall openings and / or at Crossing traffic areas 4 a receiving channel 7 bridging the respective area for media pipes and lines below the floor level in the slack-reinforced ceiling plate subsequently milled as a slot.

This slot is 7.5 cm wide and with a floor structure of 3.0 cm from floor covering 16 and floor screed 17 and a permissible slot depth of 6.0 cm in the prefabricated ceiling part a total of 9.0 cm deep. It runs from the right ceiling support to the tube bundle cutout 1 and crosses the lifting eye cutout in the ceiling plate. Since the remaining ceiling strip is not burdened by partitions, a longitudinal tear in the ceiling cannot be ruled out due to the notch effect of the slot in the extension of the tube bundle cutout, which, however, does not endanger stability and forms an additional ceiling joint.

The longitudinal axis of this channel 7 runs parallel to the slack tensile reinforcement. The integration of the media pipes and lines takes place on the existing installation in the tube bundle recess 1 in the area of the left apartment of the two-pronged floor segment shown in FIG. 2, namely in the floor below.

The receiving channel 7 with the media carriers is filled with concrete screed and closed with a leveling compound that is level with the floor.

Due to the changed cable routing, the arrangement of the wet section 2 takes place in a space bounded by load-bearing walls and new room partitions 6 on one side of the area of the building exterior wall area which has a window 5 in the area of the left apartment of the two-story floor segment shown in FIG. 2, the access to the associated right apartment is made possible by a breakthrough in the load-bearing partition.

The installation of the left apartment, which has been reduced in size after the renovation, remains unchanged.

In the area of the original location of the wet section 2, new wall openings 6, which are arranged at right angles at a distance from the supporting inner wall separating the segments and the rear of the sanitary cell, delimit a newly created side room 8 .

While maintaining the original living space area of both apartments in a two-story floor segment according to FIG. 3, the wet route 2 is shifted according to a further exemplary embodiment, by analogy to that in the first exemplary embodiment in the area of wall openings and / or when crossing traffic areas 4 in the area of the left apartment Arrangement shown with a wall opening 9 in the existing partition, while in the right apartment bridging the respective area receiving channel 10 for the media pipe for sewage 15 below the floor level in the prestressed concrete ceiling plate 14 is milled as a slot.

This slot is also 7.5 cm wide and, with a floor structure of 3.0 cm and a permissible slot depth of 6.0 cm in the prestressed concrete ceiling 14, a total of 9.0 cm deep.

Since this disturbs slot m in conjunction with the tube bundle recess 1, the transverse distribution of loads over a total length of approximately 3.0, the heavy concrete partition wall 11 is built back up to the beginning of the slot. The narrow ceiling strip lying to the side of the slot is secured by the existing profiled ceiling edges by means of shear teeth through the neighboring ceiling, so that the surface load-bearing capacity including the prestressing steel 18 and 19 is retained overall.

This ceiling strip runs from the right ceiling support to the tube bundle cutout 1 and crosses the lifting eye cutout in the ceiling plate. Since the remaining ceiling strip is not burdened by partitions, a longitudinal tear in the ceiling cannot be ruled out due to the notch effect of the slot in the extension of the tube bundle cutout, which, however, does not endanger stability and forms an additional ceiling joint.

The longitudinal axis of this channel 10 also runs parallel to the prestressed reinforcement in the lower ceiling area, this longitudinal axis lying in alignment with the tube bundle recess 1 present in the element.

The receiving channel 10 with the media pipe for wastewater 15 is also filled with concrete screed and closed with a filler layer that is level with the floor.

Due to the changed cable routing, the wet section 2 is arranged in a space delimited by load-bearing walls and new partition walls 6 on one side of the area of the building exterior wall that has a window 5 , access to the adjacent living space being made possible by a wall opening in the new drywall 6 .

The media pipe for waste water 15 is integrated in the existing installation in the pipe bundle cutout 1 in the residential area.

In the area of the original locations of the wet sections 2, new, provided with a wall opening, at right angles at a distance from the supporting inner wall separating the segments and the back of the sanitary cell rear 6 newly created side rooms 8 .
