Abstract

The invention relates to a building having a reinforced concrete wall or a reinforced concrete ceiling, wherein there are reinforcement elements (31), which extend from a wall or ceiling section, which are part of a room, to a wall or ceiling section, which are part of an adjacent room. According to the invention, the load members of said reinforcement elements are damped to improve sound insulation in the building. To this end, at least one sound diffusor (70) is provided which is in mechanical contact with the load member (32).

Description

Building with a wall and a ceiling resting on this wall, building with a wall, reinforcement element, reinforcement component and reinforcement assembly Description

The invention relates to a building with a wall and a ceiling lying on this wall according to the preamble of claim 1, a building with a wall according to the preamble of claim 6, a reinforcement element according to claim 13, a reinforcement component according to claim 23 and a reinforcement assembly, which has at least two such reinforcement elements or at least two such reinforcement components, according to claim 25.

Sound insulation is an important issue in residential and work buildings. In particular, by installing solid, sound-absorbing walls and reducing the impact sound in the false ceilings, the sound insulation in a building can be improved.

The object of the present invention is to make a further contribution to sound insulation in a building.

This object is achieved by a building with the features of claim 1, by a building with the features of claim 6, by a reinforcement element for installation in such a building according to claim 13, by a reinforcement component for installation in such a building according to claim 23 and by a reinforcement assembly according to claim 25 solved

It was found that in the case of sound transmission, the bypass transmission often makes a significant contribution to the sound transmission between neighboring rooms. In particular, the usually continuous ceiling made of reinforced concrete often plays an important role. This applies to both the lower false ceiling (i.e. the floor of the room) and the upper ceiling (regardless of whether there are other rooms above). The partition between two rooms divides such a ceiling, which rests on it, into two areas, namely a first area and a second area. In this case, one area serves as the “transmitter membrane” and the other area serves as the “receiver membrane” when transferring sound from one room to the adjacent room. The coupling of sound energy into the "transmitter membrane" can take place via impact sound as well as in the air. These two "membranes" are connected to each other by steel reinforcement elements cast into the concrete of the ceiling, at least partially under tension, each having a load bar, with each load bar having a first section concreted in the first area of the ceiling and one in the second area of the ceiling has a concreted second section and an intermediate section connecting a first section and a second section. This results in a sound transmission effect similar to that of a box telephone, with the reinforcement elements connecting the two areas taking over the function of the cord under tension in the box telephone. If it is possible to reduce the sound transmission through these reinforcement elements, an essential sound transmission path is blocked, which leads to significantly improved sound insulation. It should be noted, however, that the reinforcement cannot simply be interrupted for structural reasons.

It has been found that it is sufficient to dampen the reinforcement elements (preferably all) that connect the two areas of the ceiling to one another by in each case an intermediate section of the load bar of the reinforcement element in question having a sound diffuser in a sound-conducting (ie is generally in at least indirect mechanical contact, which in turn is in direct mechanical contact with the surrounding material, so that sound energy is conducted out of the load bar via the at least one sound diffuser, introduced into the surrounding material and dissipated therein. The connecting reinforcement element thus gives a large part of its vibrational energy to the surrounding material. ria! from. This sound energy is then no longer available for transmission to the “receiver membrane”, which results in the desired noise-reducing effect. However, the concrete of the reinforced concrete ceiling generally does not require a separation, so it is generally preferred to pour this 5 continuously.

According to the definitions made here, the connecting reinforcement element according to the invention has a load bar and at least one sound diffuser in sound-conducting contact with this load bar. For optimum formwork between the load rod and sound diffuser, it is preferable that the load rod and sound diffuser are made of the same material, usually steel. It will often be preferable for the load rod and the sound diffuser to be cohesively connected, in particular welded, in sections. As you will see later, however, this is not always mandatory. The task of the at least one sound diffuser is to couple sound energy out of the load bar and into the surrounding material. The sound diffuser thus acts as a transmitting antenna. In order to be able to fulfill this task, the sound diffuser preferably has either a large area and / or a large length and / or a suitable surface structure. A very good energy dissipation can result from the fact that the surrounding material is a granulate, in particular sand. in this case the sound diffuser excites a large number of granulate grains into small vibrations, so that many point sound sources are formed. The sound emitted is dissipated in the surrounding granulate and interfered with.

25th

The surrounding material can in particular either be concrete or - as mentioned - a granulate, such as in particular sand. In the former case, the concrete can be the concrete of the ceiling / false ceiling itself. In order to facilitate installation in the building and to rule out errors during installation, however, it is often preferred that the reinforcement element is part of a prefabricated reinforcement component. This reinforcement component can either have a block cast around the intermediate section (in particular made of concrete) or a hollow body which extends around the intermediate section and is filled with granules (in particular with sand). In the second case, the granulate is preferably compressed, so that there is good contact between the at least one sound diffuser and the granulate.

In one embodiment, the hollow body consists of a sleeve and two end pieces. As described below, such a reinforcement component is very easy to manufacture and install. In an alternative embodiment, the hollow body has a lower shell with two slotted end walls and an upper shell or a cover. A reinforcement component with such a hollow body can also be prefabricated, but its particular advantage lies in the fact that the hollow body can be arranged around the already installed connecting reinforcement element and filled with sand. In some cases, this even makes it possible to retrofit the hollow body filled with granulate when the building is being renovated. In this case, at least one sound diffuser must also be arranged on the already installed load rod of the connecting reinforcement element. To further simplify the installation and to improve the reproducibility of the installation, several such reinforcement components can be connected to form a reinforcement assembly. This can be achieved in particular in that the first sections of the load bars of the reinforcement elements are connected to one another by means of a first cross connection and that the second sections of the load bars of the reinforcement elements are connected to one another by means of a second cross connection.

For structural reasons, it is usually necessary that the first section of the connecting reinforcement element is connected to a reinforcement element that is exclusively assigned to the first area of the ceiling and that the second section is connected to an area that is exclusively assigned to the second area. ordered reinforcement element is connected. The connection can be made by wire.

It will often be preferable that the at least one Schali diffuser is integrally connected to the load bar, so that it is an integral part of the reinforcement element.

It was also found that the principle described can also be applied to adjacent wall areas of a reinforced concrete wall (usually a reinforced concrete wall). It is irrelevant here whether the two wall areas are continuously concreted or whether the connecting reinforcement element is a connecting reinforcement. Furthermore, the principle can be applied to wall areas that are aligned and angled to one another. Even if three or four wall areas meet, this principle enables a reduction in sound transmission between all areas.

The invention will now be described in more detail using preferred exemplary embodiments with reference to the figures. Here show:

17 shows a wall and a ceiling according to the prior art in a representation corresponding to FIG. 1.

FIG. 17 shows the state of the art of a ceiling 20 lying on a lower wall 10 and made of stable concrete. The ceiling 20 can be designed as an intermediate ceiling (as shown here) or can also serve as a top ceiling. Since the ceiling in the exemplary embodiment shown is an intermediate ceiling, an upper wall 12 stands flush with the lower wall 10 on the ceiling 20. Also with regard to the invention described later, it should also be mentioned that the presence of an upper wall 12 is not essential for the invention, it can thus be both a closing ceiling and a false ceiling from the ceiling.

The ceiling 20 is a reinforced concrete ceiling. So it consists of concrete 22 and cast in the concrete reinforcements, usually in the form of reinforcement mats 24, 26 made of steel. As shown, two layers of reinforcement mats 24, 26 are generally provided, the lower layer 24 forming the field reinforcement and the upper layer 26 forming the support reinforcement. As can be seen in FIG. 17, the lower wall 10 divides the ceiling 20 into a first area 20a (left in FIG. 17) and a second area 20b (right in the figure). The two areas 20a, 20b are assigned to different, but adjacent rooms. The use of reinforcement mesh is the most common Case, however, it is basically also possible to concrete other types of reinforcement elements, in particular steel reinforcement bars, as reinforcement instead of reinforcement mats. This applies to both the support reinforcement and the field reinforcement.

As already mentioned in the introduction to the description, the reinforcement plays an essential role in the sound transmission between the two areas 20a, 20b of the ceiling 20. With reference to FIG. 1, it is now explained how this sound transmission is suppressed according to the invention or at least minimized:

As can be seen from FIG. 1, the reinforcement mats (this applies to both the field reinforcement and the support reinforcement) do not extend over the lower wall 10, that is to say there are reinforcement mats 24a, 26a which exclusively cover the first area 20a of the ceiling are assigned and reinforcement mats 24b, 26b, which are assigned exclusively to the second area 20b of the ceiling 20. In the event that other reinforcement elements such as reinforcement bars are used instead of reinforcement meshes, the same applies to these reinforcement elements. For structural reasons, the respective reinforcements (in the exemplary embodiment shown, this means the reinforcement mats 24a, 24b of the field reinforcement and the reinforcement mats 26a, 26b of the support reinforcement) are each connected to one another by means of one or more connecting reinforcement elements 31. These connecting reinforcement elements 31 each have a load bar 32, which is in each case a first section 32a located in the first area 20a of the ceiling, a second section 32b located in the second area 20b of the ceiling 20, and one connecting these two sections 32a, 32b Intermediate section 32c. The intermediate section is located essentially above the lower wall 10. The first section 32a and the second section 32b can be angled, as is also shown in FIG. 1, in order to reduce the overlap length. However, a straight version is also possible. The load bar 32 could also be a Be part of a larger structure. The first sections 32a are each connected to a reinforcement mat 24a, 26a of the first area and the second sections 23b are each connected to a reinforcement mat 24b, 26b of the second area 20b. The connection is usually made using a standard wire connection. Because of this absorbing connection and due to the fact that the sections 32a, 32b of the connecting reinforcement elements 31, like the rest of the reinforcement, are cast directly into the concrete 22 (i.e. concreted in), there is no difference mechanically and statically from the prior art as he did was described with reference to FIG.

As is shown schematically in FIGS. 1, 2 and 2a, sound diffusers in the form of lamellae 70 extend from the load rod 32, namely from the intermediate section 32c. In the exemplary embodiment shown, these lamellae are plates or disks made of steel, which are essentially perpendicular to the Axialrich device of the intermediate portion 32c of the load rod 32 extend and connected to this materially, in particular welded, and thus each form part of the reinforcing element and increase its surface by a multiple. This factor of the surface enlargement is preferably at least 20, more preferably at least 50. The lamellae are preferably between 0.1 mm and 5 mm thick and preferably have an area between 10 cm ² and 500 cm ² . The slats 20 can be flat, but can also be corrugated. Furthermore, they can have openings for better connection to the material surrounding them. The lamellae can in particular also have the structure of a grater. The effect of this is as follows:

If one of the areas 20a, 20b is made to vibrate by the action of sound, this sound propagates mainly along the steel reinforcements, whereby the transmission between the two areas 20a, 20b can only take place via the connecting reinforcement elements 31. The increase in surface area in the area of the intermediate sections 32c makes a large one Part of the sound energy is diverted from the sound beam. That is, sound energy is introduced from the intermediate section 32c into the surrounding concrete, where it is dissipated. This means that much less of the schail energy that is introduced arrives in the other area of the ceiling, which results in very good sound decoupling between the rooms separated by the wall. The effect can be compared in a way with the effect if the connecting cord on a “can phone” is held with two fingers. Figures 3 and 3a show a variation of that shown in Figures 2 and 2a. Here, the lamellae 70 extend in the longitudinal direction of the load bar 32. With regard to their properties, what has been said above in relation to FIGS. As has just been described, it is fundamentally possible to directly concrete the reinforcing element comprising the lamellae (or other sound diffusers) 70 into the concrete of the ceiling. However, this requires a relatively careful handling of the reinforcement elements and an increased level of attention during concreting. As a further development of the invention, it is therefore proposed to further process the reinforcement elements by sheathing the sound diffusers to form prefabricated reinforcement components. Examples of such reinforcement components are shown in FIGS. 4 to 8: In the first exemplary embodiment, as shown in FIG. 4, the intermediate section 32c of the load rod 32 and the sound diffusers connected to it, which are designed here in the form of lamellae 70, are of a block, in particular encased by a concrete block 76. After installation in a building, the connecting reinforcement element 31 behaves statically and acoustically exactly as described above with reference to FIG. 1. Of course, the sound diffusers could also be designed differently, for example as shown in FIG. 3. FIGS. 5 to 7 show exemplary embodiments in which the sound energy is diverted from the sound diffusers not in concrete but in a granulate 34, in particular in quartz sand. In this case, this reinforcement component 30 consists of the connecting reinforcement element 31 just described and a hollow body 35 which is at least partially filled with granules 34, in particular sand, through which the connecting reinforcement element 31 extends in such a way that the intermediate section 32c of its load bar 32 extends inside of the cavity 35 filled with granules 34 and that the first section 32a and the second section 32b lie outside the hollow body 35. For reasons of corrosion protection, at least the section of the load rod 32 running through the cavity is preferably made of stainless steel. Here, the entire connecting reinforcement element 32 can be made of stainless steel, or it can be welded together from a stainless steel element and two outer non-stainless steel elements (made of "black steel").

In the exemplary embodiments in FIGS. 5 to 6, the hollow body 35 consists of a sleeve 36 and two end pieces 37a, 37b each having a passage hole. In the exemplary embodiment in FIG. 5, the sound diffusers have fins 70 (which, as in FIG. 3, could also extend in the longitudinal direction of the load bar). In the exemplary embodiment in FIG. 6, the sound diffusers have wires or sheet metal strips which connect directly or indirectly to the intermediate section 32c the load rod 32 connected, in particular welded ver. During assembly, the first end piece 37a is first arranged on the sleeve 36, so that it seals the sleeve 36 tightly on a first end face. Then the load bar is pushed through the through hole of the first end piece until the fins 70, wires or Blechstrei fen 72 are within the cavity of the sleeve 36. Now - in a standing state - granulate, in particular quartz sand or steel sand, is filled into the sleeve 36, which is closed at the bottom, and then compacted by shaking. Now the second end piece 37b is inserted into the sleeve until it is in contact with the compacted granulate and then connected to the sleeve. The Sleeve 36 is preferably a hollow cylinder. If the first end of the load bar is bent, the corresponding bending process preferably takes place only after the load bar has been pushed through the through hole of the first end piece 37 a.

FIG. 7 shows an alternative embodiment in which the sound diffuser is not integrally connected to the load bar. In this case, the sound diffuser is steel wool 74, which is introduced (in particular stuffed) before the granulate is filled into the sleeve and thus comes in sections into contact with the intermediate section 32c of the load bar. The production takes place as described above with reference to FIGS. 5 and 6.

An alternative embodiment of a reinforcement component with a granulate-filled hollow body is described with reference to FIGS. 9a to 13. This can also be prefabricated, but here it is also possible to arrange the hollow body on the reinforcement element that has already been laid (and concreted in at the ends).

A lower shell 40 of the hollow body is shown in FIGS. 9a and 9b. This has two end walls 41a, 41b, in each of which a slot 42a, 42b extends from above. In a first step (FIG. 10), the lower shell 4 is arranged on the connecting reinforcement element in such a way that its load bar 32 extends through the two slots 42a, 42b, so that its intermediate section 32c extends through the cavity surrounded by the lower shell 40 extends and the sound diffusers (shown here: lamella 70) are located within the cavity. In this case, too, other types of shield diffusers can be used.

In the next step, the remaining areas of the slots 42a, 42b are each closed with a seal 44a, 44b. These seals can be, for example, in the form of a hardening material or in the form of insertable elements, in particular in the form of elastic elements. be trained. Granulate 34 (in particular quartz sand) is then filled into the cavity, so that the intermediate section 32c and the sound diffusers are surrounded by granulate 34 (FIG. 12). Finally - if necessary after a compression step - the cavity is sealed by means of a cover 46, so that a hollow body 35 is formed (FIG. 13). In particular in the case of retrofitting, the use of steel wool as a sound diffuser (see above with reference to FIG. 7) can be useful.

As shown in FIG. 14, a plurality of such reinforcement components 30 (regardless of which embodiment) can be connected to one another, which facilitates proper laying on the construction site. Here, the hollow bodies 35 or blocks 76 extend parallel to one another and first sections 32a and second sections 32b of the connecting reinforcement elements 31 are connected to one another by means of cross-connections 52, the connection being able to be made by wire or by welding.

The ceiling is manufactured as in the prior art, with the exception that the reinforcement mats or reinforcement bars of the two areas must not be laid continuously and must be connected to the connecting reinforcement elements before being cast in concrete. Pouring with concrete, however, can be carried out continuously, as in the prior art.

As can be seen with reference to FIGS. 15 and 16, the principle just described can also be applied to the sound decoupling of adjacent wall regions 14a, 14b of a wall 14. In the exemplary embodiment shown in FIG. 10, the wall 14 is a reinforced concrete wall, to which a wall 15 (for example a brick wall) that is not connected to the reinforcement is connected in a T-shape. As described above with reference to the ceiling, the reinforcements in the two wall areas 14a, 14b are only via connecting reinforcement elements damped according to the invention

31 connected to each other. As can be seen in FIG. 16, such a connection can also take place “over a corner”. In the exemplary embodiment shown, the first wall area 14a and second wall area 14b are not cast in one piece, so that the first sections 32a of the connecting reinforcement elements 31 form connecting reinforcements. However, it would also be possible to cast the concrete of the two wall areas 14a, 14b in one piece.

In principle, any type of the reinforcement elements / reinforcement components described so far are suitable, even if only reinforcement components are shown in accordance with FIG. 5.
