Definitions

  • the invention relates to a device for impact sound insulation vertical support of a first component, in particular a precast element, on one adjacent second component, with a receptacle in one of the components and with a shear force mandrel, that cooperates with the recording at one end and with its other end towards the other Device protrudes, in the support area between Intake and transverse force mandrel an impact sound absorbing, elastic layer is arranged.
  • Such a device is e.g. from the DE-GBM 78 27 042 known. It is used there by one prefabricated stair run made of running boards and side, made of profiled steel under stairs acoustic decoupling on the inner wall of a To house. The shear force mandrel is fixed connected to the steps and the recording is in the house wall as a sleeve with a sound-absorbing lining integrated.
  • the production of the stepped fold must therefore be carried out in particular be carried out with high precision as a subsequent adjustment is not possible.
  • step folds requires both an additional one in the flight of stairs and on the platform side Stirrup reinforcement.
  • the component prepared in this way is used on the construction site with projecting shear force mandrels then with a Crane positioned. At this point they are Stair landings as components on which the stair run should be supported, at least as far as prepared, that on them recordings for those protruding from the stairs Shear force arbors are present.
  • the recordings have an elastomer layer on the underside on which the shear force mandrels rest and about the no vibrations between the shear force mandrel and recording can be transferred. So that supports the flight of stairs over the ones in the pictures Shear force mandrels impact sound insulation on the neighboring ones Components.
  • a disadvantage of one such device is, on the one hand, that the high accuracy of fit of sleeve and transverse force mandrel a high manufacturing effort presupposes and also that the recordings must be positioned exactly on the stair landing in order to with the shear force mandrels attached to the factory run of the stairs to be able to work together exactly. It is also the exact height of the contact surface of the shear force mandrel crucial in the recording because this affects that the undersides of the stair landing and run stairs without a paragraph can merge.
  • An object of the present invention is to achieve this to avoid.
  • Another object of the present invention is therefore to provide a device of the type described above which is designed so that at scheduled Overload in a stair-run side provided elastomer layer does not occur can and it is ensured that the impact sound insulation Function of the elastomer layer is not disadvantageous is affected.
  • This object is achieved in that the recording arranged in the component to be supported and the transverse force mandrel is locked in the essentially non-rotatable with respect to its horizontal Transverse axis is held in the recording and that the Lock can be canceled.
  • the object of this invention has the advantage that it is positioned component to be supported when attaching not only by a supported under this component expensive to set up support must become. Such a support would take the weight of the component to be supported caused vertical forces, so that with you accordingly no inclination as described above Shear force arbors occurred. Instead of such a support under the component are acting as torque supports directly on the shear force mandrel Locks are provided that keep the transverse force mandrel in a horizontal position, until its originally free section is held against rotation.
  • This torsion-proof holding of the originally free section is achieved one by, as before, the component, such as. B. the above-mentioned flight of stairs, is lowered with the above shear force mandrels, so that the shear force mandrel in the area of the still to be concreted, supporting Component is located, for. B. on the underpinning of a stair landing supports. This stair landing is then poured out of concrete and then after the concrete that holds the shear force pins on their outside the receiving extending portion has tied is over these sections a twist or tilt of the transverse force mandrel prevented.
  • the transverse force mandrel on its original free end with a height adjustment screw to provide for height fixation.
  • the component to be supported before concreting the adjacent one Components adjusted or adjusted in height and on the other hand is through the support of the shear force mandrel between the formwork and the lower edge to ensure a distance of the mandrel that at Concreting is filled with concrete so that the mandrel is on its entire circumference is surrounded by concrete. This is for holding the shear force mandrel in the set Concrete necessary.
  • the lock in the holder on the part to be supported is advantageously carried out over two in Axial direction of the transverse force mandrel spaced apart from one another, essentially opposite in a vertical plane acting power transmission means. So that will achieved a particularly reliable locking.
  • the power transmission means one from the outer surface of the component accessible screw connection.
  • a Screwdriver or wrench is on everyone Construction site in place, so that the release of the lock can be done with ordinary tools.
  • both power transmission means can formed by appropriate screw connections be.
  • the screw connections take over each against the receptacle and against the shear force mandrel support, depending on the arrangement, either compressive forces or but tractive forces.
  • One way to access such fittings is to ensure a parallel sleeve-shaped tube extending to the screw axis to be provided by the material surrounding the receptacle of the component runs through. That is, it extends from the screw-in point on the mount to the surface of the component. Through this, therefore a tube forming a channel can then be removed become.
  • a power transmission means can be used instead of a screw connection also through a filled container, e.g. be formed in the form of a pressure cell, its power transmission function through physical and / or chemical reactions can be canceled, so the locking repeal.
  • this is filler material a gel that pressures through the walls of the Container passes through, in particular diffuses through.
  • the pressure required for this results from the Supporting the stair element on the transverse force mandrel.
  • the gel comes out of the container relatively is slowly going on, the concrete is in the supporting, the adjacent component fixing the transverse force mandrel hardened long before lifting the container the lock noticeable.
  • the essential Advantage of this embodiment is that the Release of the lock takes place automatically and a otherwise the necessary work step is omitted. It can also not happen that when installing the stairway element you forget to release the lock.
  • the container can be emptied via diffusion, for example also with a closure that can be opened from the outside be provided. After opening, this occurs Filling material through this closure to the outside, with what the container then loses its function.
  • filling material comes in such a case, for example, sand in question, which is well suited to transfer pressure forces, on the other hand also slightly out of the open Can trickle out of the container. But it would also be one Liquid as filling material possible.
  • the filling material by other suitable chemical and / or physical processes e.g. Phase transitions, Solution processes, thermal effects, Electro-viscose processes, vibration excitation etc. is released and the container is no longer under pressure can transmit.
  • the other power transmission means a counter bearing, in particular made of elastomer. It is but also conceivable for this counter bearing steel or to use similar, because by relieving the burden Power transmission means also the counter bearing Function loses.
  • Figure 1 shows a device for impact sound insulation vertical support of a component.
  • the component is, for example, a Stair run 1 to be supported on a stair landing 2 is.
  • the staircase 1 is a precast concrete part, that is prefabricated at the factory. In this manufacturing is a sleeve 3 acting as a receptacle in the Poured in concrete, the inside at their top one Has elastomer layer 4.
  • the sleeve is made of steel, for example. she can but also from polymer concrete, fiber concrete, plastics or other materials.
  • this sleeve 3 is after setting the concrete Stair run 1 used a transverse force mandrel 5, the the elastomer layer 4 rests, the remaining space between the sleeve 3 and the transverse force mandrel 5 by insulating material 6 is filled.
  • this soft insulating material 6 on the one hand prevents the transverse force mandrel 5 and the sleeve 3 directly in contact with each other come, it is also achieved that the later Concreting the neighboring component in the concrete Gap between the transverse force mandrel 5 and sleeve 3 flows and possibly forms a rigid sound bridge.
  • the transverse force mandrel 5 On his still free end, the transverse force mandrel 5 has an adjusting screw 7 on.
  • the transverse force mandrel 5 can both a round as well as a rectangular cross section exhibit.
  • the adjusting screw 7, which is shown in FIG. 1 is a hexagon screw, is set so that when lowering the staircase 1 with a Crane the undersides 11 and 12 of the element ceiling 8 or of stairs 1 merge into each other.
  • the adjusting screw 7 is supported on a base plate 9 from.
  • the dead weight of the stair run 1 tries the transverse force mandrel 5 around the contact point of the adjusting screw 7 to turn counterclockwise. This would but the front edge 13 of the elastomer layer 4 is squeezed and the elastomer layer could then be yours No longer fulfill the function of impact sound insulation. Around To prevent this, the sleeve 3 is locked in the form of a torque support for the transverse force mandrel 5 appropriate.
  • This torque-supporting locking is shown in FIG formed by a pressure screw 14 and a counter bearing 15.
  • the counter bearing 15 is made of an elastomer material and on the inside of the sleeve 3 below placed.
  • the screw 14 runs through a tube 17 which extends from the top 16 of the flight of stairs up to as a recording acting sleeve 3 extends.
  • the tube 17 prevents that the screw 14 in the manufacture of the flight of stairs 1 comes into direct contact with concrete and concreted in becomes.
  • the screw 14 and the counter bearing 15 are in the axial direction of the transverse force mandrel spaced apart and act in opposite directions as pressure elements. This allows the shear force mandrel to be screwed over a moment can be applied as a support against the inclination mentioned above works. The shear force mandrel is locked in this way.
  • the front 19 of the stair case is then suitable Joint material 20 is occupied and then the stair landing 2 is cast from concrete.
  • This concrete encloses the free end of the transverse force mandrel 5 completely.
  • the screw 14 can be removed become.
  • the above-mentioned twisting of the shear force mandrel 5 is then through the set concrete of the stair landing 2 prevented.
  • the tube 17 is then e.g. closed with a stopper and on the stairs run 1 becomes a stair covering 21 laid. Finally, the joints between Stair run and stair landing still elastic Joint material 22 closed.
  • the mentioned joint material 20 between stairs and Stair landing can be used in addition to the acoustic function also take on the task of shear force in the event of a fire 5 protect from flames and heat. This is but also possible through other design features.
  • the transverse force mandrel 5 thus lies on its entire upper surface on the elastomer layer 4 and the counter bearing 23 is relieved of pressure.
  • the force of the lag screw 24 in the transverse force mandrel 5 takes place via an inside the transverse force mandrel arranged steel cube 25, in which the lag screw 24 through a hole in the transverse force mandrel 5 is screwed into it. But it is e.g. also possible, through a thread in or on the mandrel the force transmission ensure in the screw.
  • the supporting forces of the Tension screw 24 are a wedge 26 in the Concrete of the staircase 1 initiated. Through the oblique Side of this wedge is a good distribution of forces reached. The resulting tensile force is determined by a Reinforcement 30 introduced into the concrete.
  • An additional reinforcement 27 can be provided in the transverse force mandrel become.
  • FIG. 3 is in place of a pressure screw as in Figure 1 provides a container in the form of a pressure can 28.
  • This pressure cell forms together with the counter bearing 23 a torque-supporting lock.
  • the pressure can is filled with a gel and has a wall through which the gel under pressure can diffuse outwards. After the stair run element placed on the stair landing this pressure is exerted on the pressure can 28. Diffusing out of the gel contained in the pressure can but goes very slowly, so that the locking of the shear force arbor lasts a long time and only very slowly subsides. Until this state is reached, that is Concrete of the stair landing 2 but already hardened and takes over the anti-rotation of the shear force mandrel 5. Even with such a locking of the mandrel automatically dismantling container is another complete acoustic decoupling of the shear force mandrel possible.
  • the container 28 can also For example, be filled with sand, then through pulling a stopper to open a breech can and the sand then e.g. into the inside of the shear force mandrel 5 trickles. The container then loses its ability to transmit pressure and lock is canceled. It is also possible to do this in filling material located in the pressure cell by a dissolve physical and / or chemical process and the container thus its pressure transmission ability to take.
  • FIG of the shear force mandrel Another possibility for locking is in FIG of the shear force mandrel.
  • a Tension screw 29 becomes the transverse force mandrel 5 in the rear Area of the sleeve 3 up against the elastomer layer 4 biased. This will when you put the Stair run 1 on the element ceiling 8 of the stair landing 2 a the entire surface of the elastomer layer 4 occupying load between shear force 5 and Elastomer layer 4 reached. This load sharing due Prestress is also retained when the concrete of the stair landing 2 is solidified and the transverse force mandrel 5 clamps.
