Description

The present invention relates to a building which has at least one, arranged in at least one wall of the building and / or between a floor ceiling of the building or a base plate of the building and at least one wall of the building, parting line and arranged in the parting line vibration-damping storage facilities. Furthermore, the invention relates to a method for retrofitting vibration-damping storage facilities in a building.

Vibrations, for example, transmitted via the soil into a basement of a building, can lead to damage to the building or objects in the building or to loss of comfort for those staying in the building. Examples of vibrations often perceived as unpleasant by persons are vibrations due to vehicles passing by the building, such as railway trains or trams, road vehicles, etc. Also, vibrations occurring in a building, e.g. caused by machinery operated in the building can lead to a considerable comfort degradation for the building occupants or residents.

One approach to vibration isolation of a building is to insulate, for example, vibrations occurring outside the building at the site of formation, such as e.g. in the traffic route construction, for example in railway construction or tram construction is known by the use of vibration damping sub ballast mats. Further measures relate to the provision of slot walls or Seitenwandentkopplungen. These fixtures are relatively expensive and expensive.

Another possibility for vibration isolation of a building or a Building part is to arrange the vibration insulation in or on or under the building. For this purpose, already in the construction of a new building vibration-absorbing storage facilities, especially over the entire surface, in the masonry or structure of the building or on a base plate of a building are conveniently arranged.

The subsequent installation of vibration-damping storage facilities in existing buildings, for example to increase the comfort is possible, but so far associated with a considerable technical effort.

An example of a method for the subsequent installation of storage facilities is known from CN 1827936 A known. This document proposes to arrange the vibration-damping storage facilities next to an existing brick wall of the building, with a complex load redirection construction for redirecting the building loads on the storage facilities is needed. After curing the concrete divert construction, portions of the existing brick walls in the area between the storage facilities are removed.

Furthermore, it is known through public prior use, to separate an existing building by introducing a horizontal parting line in an upper part of the building and a lower part of the building, in the parting line, the vibration-damping storage facilities, for example, over the entire surface, are arranged. For this purpose, the upper part of the building as a whole, for example by means of a plurality of hydraulic drives, raised relative to the lower part of the building to bring the storage facilities in the parting line can. Subsequently, the upper part of the building is lowered with the interposition of the storage facilities on the lower part of the building. During the lifting of the upper part of the building, the load transfer of the upper part of the building takes place exclusively via the hydraulic drives. Overall, it should be ensured that the raising and the subsequent lowering of the upper part of the building is carried out simultaneously on all drives, otherwise locally high Force peaks occur which can cause damage to the building fabric. When lifting the upper part of the building relative to the lower part of the building there is also the risk of damage to the wiring of the existing building, for example, at the heating and / or water and / or wastewater installation.

The object of the invention is to provide a possibility for buildings of the type mentioned, which allows easy retrofitting of the vibration-damping storage facilities and in which the risk of damage to the building during installation of the vibration-damping storage facilities is reduced.

According to the invention, this is achieved by a building having the features of claim 1.

In the building according to the invention it is provided that the parting line has a sequence of apertures and joint portions, wherein in each breakthrough at least one of the joint sections opens, and in each breakthrough at least one of the bearing devices is arranged, wherein a vertical extension of the apertures is greater than a vertical extension the joint sections.

The building according to the invention is thus provided that the subsequently installed vibration-damping storage facilities are each arranged in a breakthrough of the parting line. This can be dispensed with a complete lifting of an upper building part of the building for installation of the storage facilities. The arrangement of the apertures of the parting line and the placement of the vibration-damping bearing devices takes place here at spaced-apart installation positions, wherein the number and positions of the apertures, inter alia, depending on the specific static conditions of the building can be determined. In particular, it is possible with the inventive design of the parting line, the gradually install vibration-isolating storage facilities. This makes it possible to make the retrofitting of the vibration-damping storage facilities on the existing building with relatively few and simple tools.

The at least one parting line is conveniently composed entirely of a sequence of apertures and joint sections. That is, all openings and joint portions of the parting line are advantageously successively arranged one behind the other and thus connected to each other.

By providing the parting line, the transmission of vibrations, such as structure-borne noise, is reduced. The parting line could also be used as a building joint or generally as a gap between two building components, e.g. between an upper and lower part of the building.

The parting line penetrates the respective wall conveniently in two directions completely. Advantageously, the parting line penetrates the respective wall in the wall thickness direction and in the wall longitudinal direction completely. The parting line can lie in a horizontal plane. But it is also possible that the parting line has at least partially different from a horizontal direction course.

In the joint section of the parting line, one could also speak of a slot, in particular due to the smaller vertical extent compared to the apertures. The vertical extension of the joint portion is defined for example by the cutting width of a saw blade, which is used to manufacture the Joint sections can be used. The vertical extent of the joint portion could also be referred to as gap width, which is measured in the vertical direction. Preferably, the respective joint portion penetrates the wall in the wall thickness direction completely.

In an advantageous embodiment, the joint sections have an at least substantially constant vertical extension over their entire longitudinal extent.

It is advantageously provided that the at least one joint section opens continuously into the respective opening. By the term continuous is meant in this context that the at least one joint portion with a through opening, i. without interruption of the opening, opens into the respective breakthrough.

In connection with the vibration-damping storage facilities, one could also speak of vibration damping devices or vibration damping elements. The vibration-damping storage facilities are used for vibration isolation of the building, wherein a vibration by means of the vibration-damping bearing means is completely or at least partially insulated or damped. The vibration-isolating storage facilities, also referred to in this document as storage facilities, are used for insulation or damping of mechanical vibrations, which are entered, for example, via a base plate or a basement into a building.

For the purposes of this document, a wall means a vertical component of the building arranged vertically or at least obliquely to the horizontal. In particular, the term wall does not encompass flat structural elements of the building which extend purely in the horizontal direction or lie in a horizontal plane.

The terms floor ceiling and base plate are in the Essentially horizontally oriented components of a building. Essentially in this context is meant a deviation from a horizontal plane of less than 5 ° in any direction.

It is particularly preferably provided that each vibration-damping bearing device is arranged in each case a breakthrough. It is also conceivable and possible that more than one vibration-damping bearing device is arranged in each case a breakthrough.

In a preferred embodiment it is provided that in each case one of the joint sections of the parting line opens into at least one of the openings, on opposite sides of the opening.

Particularly preferably, the building has a lower part of the building and an at least one parting line from the lower part of the building, preferably completely separated, upper part of the building, the upper part of the building, preferably exclusively, is mounted on the lower part of the building via the arranged in the apertures storage facilities. The parting line thus advantageously separates the upper part of the building completely from the lower part of the building, ie the parting line in particular passes through all the supporting walls of the building. In other words, the weight of the upper part of the building is almost exclusively on the arranged in the openings storage facilities in the lower part of the building entered. The joint sections of the parting line advantageously have no load-bearing function.

It is expediently provided that a horizontal distance between two apertures arranged adjacent to one another is in a range from 0.5 m to 12.0 m, preferably 0.5 m to 3.0 m. The adjacently arranged apertures are consecutive along the parting line. That is, there is no other breakthrough between the adjacent apertures. The horizontal distance of the adjacent openings depends on the static conditions of the building and is generally determined by a structural engineer. As the name suggests, the horizontal distance in the horizontal direction, in particular in the wall longitudinal direction of the respective wall, is measured.

In a preferred embodiment it is provided that a horizontal extent of at least one of the apertures, preferably each aperture, in a range of 0.3 m to 1.5 m, preferably 0.5 m to 1.0 m, is located.

Advantageously, the vertical extent of at least one of the apertures, preferably each aperture, is in a range of 4 cm to 20 cm, preferably 10 cm to 15 cm. The vertical extension of the respective aperture can correspond to a wall constructed of bricks, for example, the vertical height of a row of bricks of the wall.

By an optional pre-adjustment of the extent of the bias of the elastic intermediate layer, the respective bearing device can already be set during installation to the expected loads and thus reduces the extent of lowering of the upper part of the building in a direction towards the lower part of the building or a reduction can be completely prevented. Under a prestressed elastic intermediate layer is an elastic intermediate layer understood, which is compressed relative to the unloaded state. Conveniently, the elastic intermediate layer is biased in the vertical direction. The at least one spacer may have a fixed vertical extent.

Advantageously, it is provided that a material thickness of the elastic intermediate layer in an uncompressed state is in a range of 6 mm to 120 mm, preferably 20 mm to 50 mm.

Conveniently, the elastic intermediate layer is plate-shaped.

The material thickness of the backing plate, i. the thickness of the support plate is favorably in a range of 1 cm to 15 cm, preferably 2 cm to 6 cm.

The support plate is favorably stiffer or inelastic than the elastic intermediate layer. The support plate serves to distribute the loads on the at least one spacer arranged below the support plate. For example, the support plate may comprise metal or made of metal, in particular steel.

It is preferably provided that the static elastic modulus of the elastic intermediate layer is in a range of 1.0 N / mm ² to 100 N / mm ² , preferably 2.0 N / mm ² to 12 N / mm ² . The static modulus of elasticity is the secant modulus between the load zero point and a design point of the elastic intermediate layer in use as vibration insulation, ie in the installed state. The determination of the static modulus of elasticity can eg by recording the quasi-static spring characteristic with a deformation rate of 1% of Material thickness of the elastic intermediate layer per second take place, wherein the elastic intermediate layer between planar steel plates is arranged, and the third load cycle is recorded. The determination of the static modulus is conveniently carried out at room temperature.

Particularly advantageous embodiments of the invention provide that the dynamic elastic modulus of the elastic intermediate layer in a range of 1.5 N / mm ² and 200 N / mm ² , preferably between 2.5 N / mm ² and 15 N / mm ² , lies. The dynamic modulus of elasticity is conveniently measured at 10 Hz and an excitation of 100 dBv. The determination of the dynamic modulus of elasticity is conveniently carried out according to DIN 53513: 1990-03.

It can be provided that the elastic intermediate layer rests directly on an upper boundary surface of the opening.

Furthermore, it is conceivable and possible that the at least one spacer arranged below the support plate is supported directly on a lower boundary surface of the opening. However, preferred embodiments provide that a support layer, for example a mortar bed, is arranged between the spacer and the lower boundary surface.

It is conceivable and possible that between the at least one spacer and the support plate and / or between the spacer and the lower boundary surface, a spacer plate or a plurality of spacer plates for height adjustment of the bearing device is arranged on the vertical extension of the respective opening or are. Such spacer plates could also be referred to as a shim.

It is preferably provided that the intermediate layer comprises or consists of an elastomer. It is particularly favorable if the elastic intermediate layer, in particular foamed, comprises polyurethane or neoprene or silicone or synthetic rubber or natural rubber, or consists thereof. examples for possible synthetic rubbers, also called synthetic rubber, are ethylene-propylene-diene rubber or acrylonitrile-butadiene rubber or styrene-butadiene rubber. The elastic intermediate layer could also consist of a mixture of at least two of the said materials.

The elastic intermediate layer could be glued to the support plate or connected in some other way, for example by foaming the elastic intermediate layer on the support plate.

It is particularly preferably provided that the respective bearing device is arranged completely within the respective opening. That is, the respective bearing device is arranged, preferably completely, between planes in which the wall surfaces of the wall lie. The storage device is thus advantageously not on the wall thickness of the respective wall over. This allows a particularly compact design can be achieved.

In preferred embodiments, it is provided that at least one of the openings, preferably all openings, and / or at least one of the joint sections, preferably all joint sections, the parting line with, in particular elastic, joint material are sealed. The joint material may for example be a foamable material which is injected into the parting line. However, it is also conceivable and possible for the joint material to be a silicone-based, acrylic-based or bitumen-based joint material. The grout material has conveniently no load-bearing function.

The modulus of elasticity of the joint material is favorably smaller than the elastic modulus of the elastic intermediate layer. This means that advantageously no or only a negligible influencing of the vibration damping effect by the joint material takes place.

Furthermore, the invention proposes a method for retrofitting vibration-isolating storage facilities in an existing building, wherein in at least one wall of the building and / or between a floor slab of the building or a base plate of the building and at least one wall of the building, a parting line for receiving the storage facilities is introduced. The inventive method comprises the introduction of a parting line in the form of a sequence of apertures and joint sections, wherein the apertures are formed in the at least one wall and / or floor slab and / or base plate, and opens into the respective breakthrough of at least one of the joint sections, wherein a vertical extension is formed larger than the vertical opening of the at least one merging into this breakthrough joint portion, and at least one of the bearing means is arranged in a respective opening.

It is particularly preferred if during the introduction of the respective joint portion gradually intermediate plates for temporary load transfer of the building arranged in the joint portion and then the openings of the parting line are formed in the at least one wall of the building. Alternatively, it would be conceivable and possible to mold one of the apertures in the wall and / or floor slab and / or base plate in a preceding step and then to mold the joint sections opening into the breakthrough into the wall, whereby the intermediate slabs for the temporary load transfer of the building gradually become be arranged in the respective joint section.

Furthermore, at least one elastic intermediate layer and a support plate arranged below the at least one elastic intermediate layer are advantageously introduced into the opening, and the elastic intermediate layer is subsequently prestressed by means of at least one pretensioning device, preferably in the vertical direction. Furthermore, when a certain preload value of the elastic intermediate layer is reached, at least one spacer is arranged below the support plate and thereafter the intermediate plates are removed from the joint section and the at least one pretensioning device is removed from the breakthrough. Of the Preload value can be determined in advance or set during preload. For example, the preload value during preloading could be determined by detecting a light gap between the intermediate plate and the joint boundary surfaces bounding the joint sections in the vertical direction.

It is conceivable and possible to gradually mold in the apertures, wherein a subsequent breakthrough is formed only after the installation of the bearing device in the straight-shaped breakthrough in the wall. That is, the storage devices are then gradually incorporated into the respective provided breakthrough. As a result, only a few biasing devices for mounting the storage facilities are needed.

In another variant of the method, it would also be conceivable and possible, especially in the case of a wall constructed of bricks, to mold the openings first and to arrange the pretensioning devices in the openings. By means of the biasing means can then be carried out in a further lifting of the upper part of the building, wherein the joint sections by a, in particular controlled, breaking the wall, e.g. the mortar joint between two rows of bricks or the bricks themselves, be trained. For example, the mortar joint between two rows of tiles of the wall could be referred to in this context as a predetermined breaking point.

Conveniently, it is also provided here that the elastic intermediate layer and arranged below the at least one elastic intermediate layer support plate are already introduced into the opening and the elastic intermediate layer is biased by means of at least one biasing means, preferably in the vertical direction. The lifting of the upper part of the building can therefore already be done with arranged in the breakthrough elastic intermediate layer. Alternatively, the installation of the elastic intermediate layer but also at a later date, ie after lifting the upper part of the building, take place. Optionally, the row of bricks arranged under the gap which arises when lifting the upper part of the building can be removed. The thus formed overall joint portion can be filled in a further step with grout, as already explained above.

In the following explanations, the final result of the subsequent installation of vibration-isolating storage facilities 6 in a building 1 is first of all discussed. This is followed by a detailed description of the Method for installing the vibration-damping storage facilities 6 in the building 1. Subsequently, particular attention is paid to details, geometric parameters and possible embodiments of the storage facilities 6.

This in Fig. 1 Building 1 illustrated by way of example has a multi-storey construction, with a roof 20 arranged above the top floor. The building 1 has a basement floor, not specifically described, of which a predominant section is arranged below a top edge 19 of the terrain. The term of the building 1 basically includes buildings of all kinds, ie not just the house shown here schematically.

In the embodiment of the building 1, a parting line 5 is arranged in the region of the basement, above the ground level edge 19, cf. Fig. 1 and 3 , In principle, the parting line 5 or at least one additional parting line could also be arranged at another or a further installation position in the building 1, as already explained at the outset. For example, a parting line could be arranged between a base plate and at least one wall of the building or between at least one wall and a floor slab of the building. On these variants of the parting line is in connection with in the FIGS. 17 and 18 shown embodiments briefly discussed.

In the building 1 shown here, the parting line 5 is arranged in walls of the building 1, in particular in the walls 2 of the basement of the building 1.

The parting line 5 has a sequence of openings 7 and joint sections 8, wherein in each of the openings 7 at least one of the joint sections 8 opens. In the exemplary embodiment, it is provided that the at least one joint section 8 in each case opens continuously into the respective opening 7, as is also preferred.

The parting line 5 separates the respective wall 2 in two directions, namely in each case Wall thickness direction and wall length direction completely.

In the exemplary embodiment, it is thus provided that the building 1 has a lower part of the building 24 and an upper part of the building 25 which is completely separated from the lower part of the building 24 by at least one parting line 5, cf. Fig. 1 and 3 , D. h., The introduced into the walls 2 of the basement of the building 1 parting line 5 separates the upper part of the building 25 from the lower part of the building 24 completely. In this consideration, any supply lines of the building 1 and other non-structural additional walls are not meant. One could also speak of the fact that the parting line 5 in the exemplary embodiment passes through at least all the supporting walls 2 of the basement of the building 1.

In each of the openings 7, one of the already mentioned vibration-damping storage facilities 6 is arranged, see. Fig. 3 and 7 , The upper part of the building 25 of the building 1 is in the embodiment, as is also preferred, stored exclusively on the disposed in the openings 7 storage facilities 6 on the lower part 24 of the building 1. In other words, the upper building part 25 of the building 1 is supported by the storage facilities 6 on the lower building part 24 of the building 1. While the upper part of the building 25 of in Fig. 1 shown building 1 before the introduction of the parting line 5 in the walls 2 of the basement floor was rigidly coupled to the lower part of the building 24 and thus, inter alia, large-scale sound bridges were formed in the building 1, the parting line 5 allows a relative movement or decoupling of the upper building part 25 relative to the lower part of the building 24. As a result, the transmission of vibrations, for example, the lower part of the building 24 is exposed due to transmitted via the soil vibrations or vibrations, insulated or damped on the upper part of the building 25 of the building 1.

In Fig. 2 the distribution of the sound-absorbing storage facilities 6 in the plan of the building 1 is shown. For clarity, was in Fig. 2 on the representation of the breakthroughs 7 and on the designation of each of the sound-absorbing storage facilities 6 and each of the joint sections 8 omitted. Basically, that corresponds Fig. 2 a view from above of the lower building part 24 of the building 1, ie a floor plan of the building 1 in the region of the parting line 5. The storage facilities 6 are shown hatched in this illustration for clarity. Between each adjacent storage facilities 6, the joint sections 8 of the parting line 5 can be seen. Additionally is in Fig. 2 an exemplary, reaching into the interior of the building 1 wall 2 of the building 1, which emanates from a wall junction 27 of one of the peripheral walls 2 of the building 1. Thus, in addition to the peripheral walls 2 of the building 1, an additional supporting wall 2 of the lower building part 24 is shown. In the view according to Fig. 2 the wall 2 extending into the interior of the building 1 has a free end 28, wherein one of the bearing devices 6 is arranged at the free end 28. In the arranged at the free end 28 of the wall 2, unspecified, breakthrough 7 opens only a joint portion 8 a.

Furthermore is in Fig. 2 clearly seen that, apart from the aforementioned special case, in which only one of the joint sections 8 in the free end 28 of the interior of the building 1 reaching wall 2 arranged opening 7 opens, otherwise all joints sections 8 of the walls 2 each at least two adjacent arranged breakthroughs 7 connect together and open into this. The arranged in the region of the wall junction 27 joint portion 8 opens in the embodiment in three adjacently arranged apertures 7, wherein in Fig. 2 - As already mentioned - only arranged in the openings 7 storage facilities 6 are shown. The in Fig. 2 illustrated plan is to illustrate different possibilities of configuration or the course of the parting line 5 and represents only one possible example of a building 1.

In Fig. 3 is clearly seen that in the mutually adjacent openings 7, which are each connected by means of a joint portion 8, on opposite sides of the respective Breakthrough 7, each one of the joint sections 8 of the parting line 5 opens.

The joints sections 8 are in the Fig. 1 to 13 illustrated embodiment arranged in a common, horizontal plane.

It is envisaged that a vertical extension 9 of the openings 7 is greater than a vertical extension 10 of the joint sections 8, cf. eg Fig. 3 to 7 ,

In the following, the method for retrofitting the vibration-damping storage facilities 6 in the building 1 with reference to the 4 to 12 explained in detail.

In Fig. 8 is the initial state of one of the walls 2 of the building 1 before the introduction of the parting line 5 in a sectional view exemplified. The upper and lower part of the building are in Fig. 8 not separately designated, since these are in this initial state of the illustrated wall 2, in particular cohesively, connected to each other.

In a first step of the method, the parting line 5 is now introduced into the wall 2. As already explained, the parting line 5 comprises a sequence of openings 7 and joint sections 8, wherein Fig. 4 one of the openings 7 of the parting line 5 is shown in detail. In order to mold the parting line 5 into the at least one wall 2, the joint sections 8 can, for example, be introduced into the wall 2 with a saw, in particular be sawn, and the respective openings 7 can be produced below. But this is only one example of the introduction of the parting line 5, wherein the sequence can be selected depending on the static conditions of the building 1. For example, the respective opening 7 could also be introduced into the wall 2 with a saw, eg a concrete saw. Other tools can basically - depending on the structure of the wall 2 - are used to form the parting line 5. For example, a respective opening 7 could be formed by means of side-by-side and / or overlapping core bores.

In the exemplary embodiment, the walls 2 of the existing building 1 are made of reinforced concrete. Alternatively or additionally, the respective wall could also be constructed of brick bricks, rammed earth, or wood, or at least two of the said components. The subsequent installation of the shrinkage-absorbing storage facilities 6 is conceivable and possible in all these mentioned structures of the walls 2 of a building 1.

During the introduction of the at least one joint section 8, as is also preferred, intermediate plates 17 are arranged for temporary load transfer of the building 1 in the respective joint sections 8. As a result, the load of the upper building part 25 can be transmitted via the intermediate plates 17 to the lower part of the building 24, cf. Fig. 4 , The intermediate plates 17 may be made for example of a steel sheet.

Conveniently, the material thickness of the intermediate plates 17 corresponds in each case to a vertical extension 10 of the joint sections 8. The intermediate plates 17 can, for example, be hammered into the respective joint section 8 with a hammer. With progressive formation of the respective joint portion 8 in the longitudinal direction of the wall 2, e.g. sawing, the already inserted intermediate plates 17 are gradually trapped between the upper part of the building 25 and the lower part of the building 24. This results in a generally very low local lowering of the upper building part 25 in the direction of the lower building part 24. The minimum local lowering of the building part 25 is from a static point of view, compared to the complete lifting and subsequent lowering of the building part according to the state technology, negligible.

For easier insertion of the intermediate plates 17 into the respective joint section 8, a respective intermediate plate 17 may optionally have at least one wedge-shaped insertion section, as shown in FIG Fig. 9 is indicated.

In the following step, an elastic intermediate layer 12 of the bearing device 6 and arranged below the elastic intermediate layer 12 support plate 13 of the bearing device 6 is inserted into the opening 7. Furthermore, the elastic intermediate layer 12 is biased by means of at least one biasing device 18 in the vertical direction. In the embodiment shown, two biasing means 18 are provided, see. Fig. 5 ,

The support plate 13 is used to distribute the loads on the biasing means 18 and for distributing the loads on the elastic intermediate layer 12th

The support plate 13 is favorably stiffer and inelastic than the elastic intermediate layer 12 is formed.

The biasing means 18 may, as provided in the embodiment, be hydraulically driven. In the exemplary embodiment, hydraulic cylinders are used, which are driven for example by means of a hydraulic pump not shown separately. Other biasing devices are of course conceivable and possible, for example, mechanical biasing devices, such as hand-operated spindle drives, or electromechanical biasing devices. Such biasing devices are well known.

With increasing bias of the elastic intermediate layer 12, the elastic intermediate layer 12 is compressed more and more, wherein the arranged in the adjoining the breakthrough 7 joint sections 8, intermediate plates 17 are more and more relieved.

Upon reaching a corresponding bias value of the elastic intermediate layer 12, arranged in the joint sections 8 intermediate plates 17, conveniently completely relieved. This means that the local load of the upper building part 25, at least for the most part, is removed via the elastic intermediate layer 12 and the support plate 13 as well as the pretensioning devices 18 to the lower building part 24.

In the following step, spacers 14 of the bearing device 6 are arranged below the support plate 13. The spacers 14 rest in the exemplary embodiment on a support layer 15. The support layer 15 is conveniently a mortar bed, which is designed so that after curing of the mortar bed reliable transfer of building loads of the upper building part 25 via the spacers 14 on the lower Building part 24 is done.

To compensate for any differences in height, 14 additional compensating plates can be inserted above or below the spacer, which are not shown in the figures for reasons of clarity.

The spacers 14 are made in the embodiment of steel. In principle, other materials come into question, which withstand the expected loads.

After curing of the optional support layers 15, the intermediate plates 17 are removed from the adjacent to the opening 7 joint sections 8. Due to the bias of the elastic intermediate layer 12 by means of the biasing means 18 and the associated relief of the intermediate plates 17, the removal of the intermediate plates 17 can be done by hand or with the aid of a hammer.

Furthermore, the biasing means 18 are removed from the opening 7. The entire local load of the upper building part 25 is now transmitted via the arranged in the opening 7 storage device 6 to the lower part of the building 24. In other words, the upper part of the building 25 is now stored locally via the bearing device 6 on the lower part of the building 24, cf. Fig. 7 ,

After installation of the storage device 6 in the example in Fig. 7 represented breakthrough 7, a further storage device 6 can be arranged in an adjacently arranged opening 7, wherein in the FIG. 4 to 7 be repeated steps shown accordingly. In this context, it is pointed out that it is possible to extend a respective joint section 8, which opens into the first formed opening 7, only after installation of the bearing device 6 in the opening 7 to the adjacent opening 7 out.

The formation of the parting line 5 and the arrangement of the vibration-damping bearing means 6 in the respective openings 7 makes it possible to dispense with a complete lifting of the upper building part 25 relative to the lower part of the building 24. Since a lifting of the upper building part 25 is not necessary, damage to the wiring of the building 1, for example, at the heating and / or water and / or wastewater installation can be avoided.

In an alternative procedure, it would be conceivable and possible to form a second perforation 7 in the manner of a so-called pilgrim step method first and only after installation of the corresponding vibration-isolating bearing device 6 in the next breakthrough 7, in the breakthrough 7 still to be formed between these breakthroughs 7 a vibration-isolating bearing device. 6 install. Such approaches are known in other fields of construction. With this procedure in the manner of a pilgrim step method, the danger of crack formation can be reduced, in particular in the case of components of building 1 susceptible to cracking.

That is, the weight of the upper building part 25 is entered almost exclusively on the storage facilities 6 in the lower part of the building 24.

After installation of the storage facilities 6, it is advantageous to at least partially fill the respective opening 7 with a joint material 16 in order to seal the building 1. In the exemplary embodiment, it is provided that the respective opening 7 and the joint sections 8 opening into the respective breakthrough 7 are filled with grout material 16 or are, cf. Fig. 7 , It is particularly advantageous if the entire parting line 5 is filled with grout material 16 or is.

The joint material 16 in the exemplary embodiment is a foamable polyurethane foam. Such foamable grout materials 16 for sealing, mounting or filling joints are well known in the construction industry. Foamable joint material is also referred to as gun foam, construction foam or mounting foam. Other joint materials can be used, as explained above.

The modulus of elasticity of the joint material 16 is smaller than the modulus of elastic intermediate layer 12. This prevents the formation of a possible sound bridge between the upper part of the building 25 and the lower part of the building 24 via the joint material 16. The joint material 16 has no significant supporting function.

As already mentioned, the vertical extension 9 of the respective opening 7 is made larger than the vertical extension 10 of the at least one joint section 8 opening into this opening 7, cf. Fig. 4 7. Conveniently, the vertical extension 10 of the joint portion 8 corresponds to the Schnittbereite a saw blade of a saw, in particular a concrete saw.

The selected horizontal distance 21 is dependent on the static conditions of the building 1 and its construction. The horizontal distance 21 between two mutually adjacent openings 7 is in Fig. 13 drawn by way of example, wherein in this illustration no storage facilities in the adjacent openings 7 are shown. With the dot-dash lines drawn in this figure, it is indicated that only a partial section of the wall 2 is shown. The horizontal distance 21 between two mutually adjacent openings 7 corresponds to a flat wall 2 of the horizontal extent of the opening in the adjacent openings 7 joint portion 8, see. Fig. 13 ,

In the exemplary embodiment, it is provided that the joint sections 8 have a constant vertical extent 10. It would also be conceivable and possible that the vertical extension 10 of the joint sections 8 over the longitudinal extent of the respective joint portion 8 is variable. However, at least in the region of the junction of the joint section 8 into the respective opening 7, it is expediently provided that the vertical extension 10 of the opening joint section 8 is smaller than the vertical extension 9 of the opening 7.

In the exemplary embodiment, the joint sections 8 extend substantially in the horizontal direction. One could therefore designate the vertical extension 10 as the gap width of the joint sections 8.

Relative to a vertical direction, the respective aperture 7 has an upper boundary surface 22 and a lower boundary surface 23. The bearing device 6, at least in an installed state of the bearing devices 6, is arranged between the upper boundary surface 22 and the lower boundary surface 23. In the exemplary embodiment, it is provided that the elastic intermediate layer 12 bears directly against the upper boundary surface 22, cf. Fig. 7 , In another embodiment, it would be possible to provide an additional layer, in particular an additional elastic intermediate layer, between the upper boundary surface 22 of the opening 7 and the elastic intermediate layer 12.

The respective, designed as a mortar bed, support layer 15 is arranged in the embodiment on the lower boundary surface 23 of the opening 7, see. Fig. 7 ,

This can be the sectional views of the FIGS. 11 and 12 be removed. In other words, an expansion of the bearing device 6 in the wall thickness direction of the respective wall 2 is less than or at most equal to the wall thickness 26 of the at least one wall 2. As a result, the respective bearing device 6 is completely integrated in the respective wall 2 in the exemplary embodiment.

In the exemplary embodiment, the elastic intermediate layer 12 is plate-shaped.

Subsequently, the openings 7 for receiving the storage facilities 6 could be introduced gradually. Alternatively, in a second step, all apertures 7 could first be formed before the bearing devices 6 are arranged in the apertures 7.

An advantage of the invention is also that storage facilities 6 can be exchanged if necessary in a simple manner. For this purpose, the optionally existing joint material 16 is removed from the opening 7 and the opening into the opening 7 joint sections 8 in a first step. In addition, the biasing means 18 are accordingly Fig. 6 arranged and the support plates 13 and the elastic intermediate layer 12 is raised. Furthermore, the spacers 14 are removed and the intermediate plates 17 are inserted in the joint sections 8. Subsequently, the elastic intermediate layer 12 is relieved.
