    The invention relates to a device for preventing sound transmission through an opening or a production-related duct in a wall according to the preamble of claim 1. The invention further relates to a method for soundproof closing an opening or a production-related duct in a wall according to the preamble of claim 11.
    When creating walls from concrete with large-area formwork, it is necessary to keep the formwork panels forming the formwork at a precise distance from each other and to absorb the pressure generated by the liquid concrete with tie rods. For this purpose, spacer tubes are used between the two formwork panels forming the formwork for the wall to be created. The length of these spacer tubes, with the other ends attached, corresponds to the thickness of the wall. The tensioning rods are passed through the spacer tubes and also through the adjacent formwork panels. Nuts are placed on the free ends of the tension rods, which protrude beyond the outer skin of the formwork panels, which rest on the outside of the formwork panels and can thus absorb the forces from the backfilled liquid concrete mass. After the concrete mass has hardened and the formwork panels and tie rods removed, passages or openings remain in the freshly created wall, which connect the two surfaces of the wall. The two openings of these passages are usually closed by plastic pins.
    In residential construction, where high demands are placed on noise protection and sound insulation, these cavities form sound bridges between the two locking plugs. In concrete stairwells, for example, the footsteps and voice sounds generated there penetrate the walls and disturb people in living rooms in the adjacent apartments or offices.
    It is known from the prior art, in such cases or in the areas where no sound transmission may take place, either to stuff the cavities with rock wool or to fill them with cement or mortar. Both approaches are very labor intensive and, if not done carefully and without an air gap, the sound can still penetrate the wall. Spacer pipes filled with mortar become sound-permeable again after the mortar has hardened due to its shrinkage.
    An object of the present invention is to provide a device with which the sound transmission through spacer pipes in concrete walls or through other manufacturing channels resulting in the manufacture of concrete walls in the wall or wall openings is prevented. The degree to which sound transmission is prevented must at least correspond to the value that the surrounding wall area of the spacer tubes enables.
    Another object of the invention is to provide a device that is inexpensive to manufacture and can be used with little effort. Another object is to create a method that simplifies the closing of the sound-conducting area of the spacer tube.
    Another object is to provide a device which can be used in pipes with large fluctuations in the inner diameter soundproof.
    This object is achieved by a device according to the features of claim 1 and a method according to claim 11. Advantageous embodiments of the device are described in the dependent claims.
    According to the invention, a device for preventing sound transmission, e.g. provided by a spacer tube made of plastic, concrete or steel for tension rods and other manufacturing-related areas penetrating the walls of concrete structures, in which after the completion of the concrete wall, a sound-absorbing material is introduced into the spacer tube or into the openings of different cross-sections, the sound-absorbing material being prefabricated cone-shaped or rod-shaped insulating body and is designed to be insertable into the opening or channel.
    The device is further characterized in that the sound-absorbing material is embedded in a tubular or tubular jacket, which jacket can be inserted into the opening. The device can be inserted without tools and with minimal expenditure of time.
    Furthermore, the device is characterized in that concrete, mortar, fibrous material, foam or solid plastic or a material that absorbs noise is used as the sound-absorbing material. In particular, the tubular or tubular jacket can comprise a winding tube made of paper or plastic, a tube or a tube. In the case of a winding tube made of paper, this can be moistened before being pushed into the opening, so that after the paper is swollen, the device is clamped in the opening without air gaps.
    Preferably, the rod-shaped insulating body has a length that corresponds to the length of the opening or is shorter than the opening, the non-clogged area being closed by end caps or pins. With a precisely specified length, maximum sound insulation can be achieved.
    Even with an extremely sound-absorbing material, a maximum of sound insulation can be achieved if this is designed as a cylinder or differently shaped element and the spacer tube is closed by two conventional locking pins at the ends.
    In a particularly advantageous embodiment of the device, the insulating body is attached to a locking pin for closing the insulated spacer tube. In the case of a device which is connected to the locking pin, there is no additional need for action, since when the locking pin is pushed into the end region of the spacer tube, sound insulation is ensured at the same time.
    In another preferred embodiment of the invention, rod-shaped insulating bodies are attached to the closing pins for closing the spacer tubes or are formed as part of the closing pins, wherein the insulating bodies can be shorter than the spacer tube. The front end of the insulating body or locking pin is preferably tapered. The remaining part is slightly larger than the cross section of the opening to be closed in order to obtain a secure airtight and soundproof closure. The outer surface of the insulating body or locking pin can comprise additional circumferential lamellae, ribs or O-rings, which further reliably prevent the passage of sound through the labyrinthine design. In a further special embodiment of the insulating body, the surface thereof can be coated with flocking or a foam rubber coating, and the formation of a gap between the spacer tube and the insulating body can thereby be compensated for. Instead of flocking, the surface can also be coated with a very soft plastic or a foam in order to achieve the same goal, namely the consequent prevention of an air gap.
    If the locking pin is made directly with sound-absorbing material, additional time and cost savings can be made and it is also ensured that there are no spacer tubes without sound insulation.
    The are preferred. rod-shaped insulating body prefabricated to the size of the usual thickness of walls.
    Alternatively, rod-shaped insulating bodies can be produced in greater lengths and cut at the construction site before insertion into the opening or, if longer pieces are introduced, the protruding areas can be separated or chipped off. When using rod-shaped insulating bodies that are longer than the thickness of the wall, the logistics are simplified because the correspondingly cut insulating bodies do not have to be ordered and provided in advance, but are adapted to the thickness of the wall as required. The rod-shaped insulating bodies can be prefabricated in an automated manner and therefore manufactured at low cost, and are light and can be transported to the construction site in the quantity required.
    When using wrapping tubes made of paper, these or a soft coating applied to them can be briefly moistened before insertion into the spacer bars, so that the opening can be sealed tightly by swelling of the paper.
    The prefabricated rod-shaped insulating bodies can also be moved by inexperienced auxiliary personnel and nevertheless optimal sound insulation can be achieved without the need to practice complicated procedural steps.
    An embodiment of an opening or channel, the invention is explained in more detail using a spacer tube. It shows:<tb> Fig. 1 <SEP> an arrangement of a spacer tube between two formwork panels with an inserted tie rod according to the prior art,<tb> Fig. 2 <SEP> a first embodiment of an insulating body to prevent sound transmission,<tb> Fig. 3 <SEP> another version of a spacer tube with detachable end pieces,<tb> Fig. 4 <SEP> a cross section through a wall made of concrete after stripping,<tb> Fig. 5 <SEP> a cross section through the wall according to FIG. 4 with the sound-absorbing and sound-absorbing insulating body inserted,<tb> Fig. 6 <SEP> a cross section through the wall with a sound-absorbing insulating body made of a winding tube with a filling of concrete or mortar,<tb> Fig. 7 <SEP> a cross section through a wall with a spacer tube, which is closed on both sides with locking pins and an insulating body in between,<tb> Fig. 8 <SEP> different caps for closing the open ends of the spacer tubes on the finished wall with and without a rod-shaped sound-absorbing insulating body.
    Fig. 1 shows a known from the prior art spacer tube 1, comprising a substantially cylindrical guide tube 3 with an inner circumferential surface 13 and an outer circumferential surface 15 and two end pieces 5 arranged at the front ends of the guide pipe 3. The end pieces 5 are inserted into the guide tube 3 in this known spacer tube 1 according to FIG. 1. They comprise a conical jacket 7, which comes to lie outside the guide tube 3, a cylindrical section 9. The two end pieces 5 are inserted into the guide tube 3 between two formwork panels 11 before being inserted. The end pieces 5 can be brought together with the guide tube 3 at the manufacturer or at the construction site. This assembly work is usually done on site. The end pieces 5 can initially be completely or only partially inserted; however, as soon as a tie rod 12 is inserted into the guide tube 3 and the formwork panels 11 are pressed against the spacer tube 1 with nuts (not shown in FIG. 1), the cylindrical sections of the end pieces 5 slide completely into the guide tube 3.
    After the mutual bracing of the two formwork panels 11 and the necessary reinforcing iron, the space between the formwork panels 11 can be filled with liquid concrete. The formwork panels remain on the wall until it is at least partially cured.
    After curing, the formwork panels 11 can be removed after loosening the nuts on the tie rods 12 and the tie rods 12 can be removed from the spacer tubes 1. The end pieces 5 are also removed by pulling them out of the surface of the finished wall 15. What remains are frustoconical recesses 21 in the surface of the wall 15 and cylindrical spaces connecting the two surfaces of the wall 15.
    To prevent the passage of sound through the passages from one side to the other of the wall 15, the material which is intended to insulate the sound is introduced as a rod-shaped insulating body 21. In a first embodiment according to FIG. 5, a cylindrical insulating body 21, as shown in FIG. 2, which is shorter than the length of the guide tube 3, is pushed into the latter. The length of the insulating body 21 is dimensioned such that a locking pin 25 can still be inserted into the guide tube 3 from each side, so that the frustoconical recess 23 can be closed aesthetically clean. The rod-shaped insulating body 21 can consist of concrete or mortar or of another sound-absorbing or non-sound-conducting material such as plastic, hard foam or a pressed material that preferably does not absorb water and is moisture-resistant.
    In a further embodiment, the insulating body 21 comprises a sleeve 25 made of cardboard, preferably a winding tube made of paper, the interior 29 of which is filled with mortar, concrete or another suitable sound-absorbing material (FIG. 3). The sleeve 27 can also consist of a closed-pore rigid foam or a hose.
    The guide tube is shown in partial cross-section through the wall 15 according to FIG. 4, designated by reference symbol 3. On both ends of the guide tube 3, the conical indentations of the pin regions 19 can be seen, which have become visible after the end pieces 5 have been removed. It can also be seen that there is now a direct connection from both sides of the wall 15 through the interior of the guide tube 3 and consequently any sound, no matter how thick, can penetrate the wall 15 unhindered. This cylindrical space 17, which has a diameter of the order of 20 mm to 36 mm with a tolerance of up to 3 mm, has been previously filled with rock wool, i.e. The rock wool has to be manually stuffed into these narrow channels up to several meters long in power plants.
    In another known embodiment (FIG. 5), concrete or mortar is poured into this horizontally running narrow space. This is complex and, above all, the 100% filling or seal is hardly achieved, since after curing, a narrow gap lets noise through when shrinking.
    6 now shows an embodiment of an insulating body 21 according to the invention, which has been inserted axially into the guide tube 3. The diameter of the insulating body 21 has an outer diameter which lies airtight on the inner diameter of the guide tube 3 and is consequently somewhat larger than the inner diameter of the guide tube or breakthrough channel and has a conical end. The insulating body 21 can be shorter than the guide tube 3 in order to be able to use a locking pin 25 on both sides, which, held in the end regions of the guide tube 3, completely or partially fills the truncated cone-shaped pin region 23 in order to satisfy the aesthetics, including the visible remains to remove from the spacer tube. The locking pin 25 will be described later.
    In a further embodiment of the insulating body 21, this comprises a sleeve 27, for example made of cardboard or paper or another inexpensive material, in which concrete, cement, mortar, insulating foam or a plastic mass is filled. The diameter of the sleeve 27 is dimensioned so that it is easy to insert. If the sleeve 27, if it is made of paper, has been briefly moistened beforehand, it expands after being inserted into the guide tube 3. The pin region 19 is closed as described for FIG. 5. Of course, the recess could also be filled with mortar instead of a locking pin 25.
    Through the inserted insulating body 21 it can be achieved that the sound penetrating the spacer tube 1 is at least not greater than that which penetrates the surrounding wall, that is to say there is no longer a sound bridge.
    Further configurations of the insulating body 21 are shown in FIG. 8. The insulating body 21 is either plugged into a corresponding receptacle on the locking pin 25 and projects into the interior of the guide tube 3 after the locking pin 25 has been put on (FIGS. 8b and 8d). The length of the insulating body 21, which is attached to the locking pin 25, is preferably slightly less than half the thickness of the wall 15. If a particularly good insulating material is used for the insulating body 21, the length can be much less than half the thickness of the wall 15.
    The locking pin 25 shown in Fig. 8c can consist in a further embodiment as a whole of the material used for the insulating body 21, i.e. the conical pin region 19 is not made of plastic, but of the same material as the insulating body 21, e.g. made of concrete, mortar, plastic or another sound-absorbing or sound-absorbing material.
    With such locking pins, the passage of sound through the spacer tube 1 can be prevented from both sides of the spacer tube 1. The position of the locking pin 25 shown in FIG. 8a can be seen on the left in FIG. 7.
    8c and 8d show a recessed locking pin with sound insulation. Such locking pins 19 also serve to close the ends of the spacer tube 1 if no insulating body 21 is inserted between the locking pins 25 in the center of the spacer tube 1.
    In a further embodiment, circumferential lamellae 26 can be formed on the closure pin 25 for a tight closure with the opening. The fins 26 act as a labyrinth and consequently the fins 26 do not have to lie snugly against the spacer tube 1. Of course, fins 26 and, for example, flocking can also be combined with one another on the outer surface of the spacer tubes 1.
    Analogously to the prevention of sound transmission through a spacer tube 1, the insulating bodies with a corresponding geometric shape can of course also be used for sound insulation or sound absorption in openings in walls in which no pipes have been used.
