Description

The present invention relates to a device for elastic storage a concrete component on a substrate to create a mass Spring system, the concrete component being the mass and a between the concrete component and the underground spring device arranged Spring represents, with a housing in the concrete and the Fe the facility. The invention further relates to a method for elastic storage of a concrete component on a surface with means of a mass-spring system, the concrete component being the mass and a Fe arranged between the concrete component and the subsurface dereinrichtung represents the spring, with a housing for receiving the spring device is arranged in the concrete and the housing one Has bulge.

In some applications, concrete components are used as a base for rail-guided vehicles used. Especially in tunnel construction There are increased demands on the storage of the rails, because tunneling through the rolling process of the wheel on the rail work can be excited to vibrate. These vibrations can NEN spread as elastic waves in the surrounding soil. To meet this on a building foundation, the structure becomes vibrations stimulated. The consequence of these vibrations can be caused by noise pollution Air, sound and structural vibrations. Through suitable modifications  the superstructure, for example mass-spring systems, can Wave propagation in the subsurface can be prevented or reduced. In As a rule, the mass-spring systems consist of the main components Track grate or track support plate, concrete trough (mass) and elastic Bearing (spring).

There are several different types of mass-spring systems Manufacturing process known. Among other things, elastomer strips or individual storage installed with the help of a mineral wool mat. In the area A mineral wool mat is spread out between the bearings. The height this mat must be calculated so that it is at a certain Pressure that corresponds to the load of the entire concrete trough is smaller than the height of the elastomer bearing. In the first concreting step, only one thin layer of concrete applied so that the mineral wool the concrete weight can still carry completely. After this layer has hardened the entire cross-section is concreted. The mineral wool is like this widely compressed that the total mass on the elastomers rests. The disadvantage of this method is that it is very time-consuming is because the hardening of the first layer of concrete must be completed first must before the final concreting process can take place.

The object of the present invention is therefore the storage of a loading to enable clay component quickly and inexpensively.

The task is solved with the features of the independent claims che.

According to the invention, the device for elastic mounting has a Concrete component on a base, a housing and a spring direction up. The housing is essentially tubular. In a bulge is arranged in the housing, in which at least  part of the spring device is added to support the loading clay component opposite the underground.

The housing, which is anchored in the concrete component, allows this Insert the spring device up to at least partially under the concrete component. The concrete component can first beto together with the housing be kidneyed. Then the spring device is in the housing introduced and at least partially brought into the bulge. The Fe The element is therefore able to have a corresponding dimension tion of the spring device in relation to the bulge of the concrete component without contacting the ground. The concrete component, which in the system represents the mass and the spring device, which the Fe which represents, thus form a mass-spring system, which one emerges excellent sound and vibration insulation of the concrete component. Through the housing, the spring device can again if necessary be removed. It is therefore possible to have a defective spring device exchange or at least for maintenance or inspection purposes to remove temporarily. This is particularly possible because übli a large number of devices according to the invention wear clay component and thus individual spring devices for this Maintenance work can be removed briefly without the The entire system would have to be destroyed.

A particularly advantageous spring device has an elastomer block as a spring. Such elastomer blocks are ideally suited for to carry heavy concrete components. The spring behavior as well as the durability Stability of the elastomer block is special for the present application advantageous. Alternatively, however, others can of course also be used, for example Coil springs are used.

If the spring device has a closure plate, it is possible to that the spring part is inserted into the housing and by pressing together  the spring device or by lifting the concrete component Locking plate can engage in the bulge. This will create a Locking the spring device with the housing causes, whereby the concrete component even when subsequently loaded by the concrete component Spring is raised accordingly, so that a connection between the concrete component and the underground is avoided.

It is particularly advantageous if between the closure plate and the elasto merblock a sliding washer, especially made of lubricated steel is there. Through the sliding washer, it is possible to open the closure plate to rotate the elastomer block and thus from an open to an to move the closed position. It becomes the friction between the elastomer block and the closure plate reduced. The closing the spring device in the bulge of the housing is thus we considerably relieved.

A further bulge is advantageously provided in the housing assigns. In this further bulge there is at least partially one Pressing device added. By means of the pressing device it is possible to lift the concrete component. Is this lifting of the concrete component like this high that the spring device fits into the bulge, so the Fe the device introduced into the first bulge and the press device again can be relieved. As a result, the concrete component sits on the spring device and is abge on the first bulge supports.

The pressing device has in particular a hydraulic press. through Hydraulic presses are possible, even large-scale, heavy concrete construction lifting parts.

Through a closure plate, which is integrated in the pressing device, the pressing device is introduced into the housing and with the other  Bulge locked. By pressing the press device Force over the closure plate and the further bulge in the concrete component introduced to be able to lift this.

For particularly easy insertion and removal of the spring direction or the pressing device, in particular the respective Ver end plates, it is advantageous that the bulge on a channel points, which extends to the upper end of the housing. Through this Channel become projections of the respective closure plates to the end bay of the housing inserted and can then by Twist locked into the bulge.

Are several bulges and / or Ka on the circumference of the housing channels arranged so that an even load on the housing and thus an even introduction of force into the concrete component through the Spring device and / or pressing device, for example via the Ver end plates are made. In this case, closure plates have several Projections on which with the bulges and / or channels of the Housing correspond.

If the bulge has a locking device, it is secure Positioning of the spring ensured.

With a carrier arranged on the device for load distribution a simple and effective force application of the mass into the spring created.

In order to enable advantageous operation of the device and that To be able to make the housing as small as possible is one on the housing Recess for supply lines of the press provided.  

A method according to the invention for the elastic storage of a concrete component on a substrate using a mass-spring system follows in that the concrete component is lifted off the ground, the Fe the device inserted into a bulge of a housing and then the concrete component is drained again. The Federein direction can, for example, from a single spring or an Ela stomer block exist or locking elements, such as as have closure plates which, for example, in the bulge by inserting or screwing in. The out Bearing serves to lock the spring device with the Ge housing and thus with the concrete component.

Because the concrete component is lifted from the ground as far as possible, that the spring device is at least partially inserted into the bulge assembly is particularly easy. If the Be clay component drained again after attaching the spring device, so the concrete component sits on the spring device and thus forms that Mass-spring system for isolating sound and body vibrations. The spring device can be dismantled in the same way. To do this, the concrete component is lifted off the surface. As a result, the spring device is relieved, and can thus from the Bulge can be removed again. Then the concrete can component drained or, depending on the application, also during the Leave maintenance work briefly in the off-hook condition ben. The spring device is removed, inspected or replaced and can be reinserted into the housing and bulge if necessary be set. Then the concrete component can be inspected again or replaced spring component or if necessary also on the sub reason to be put on.  

To lift the concrete component, a pressing device is placed in a wide area re bulge inserted. This makes it possible for the press direction is only installed if necessary. As soon as the concrete component is on the spring device sits, the pressing device from the housing and the further bulge can be removed again by the Pressure device is relaxed and thus has a lower height, in order to be able to be removed from the bulge again.

Before lifting the concrete component, it is advantageous if a press the pressing device together with a closure plate, which in the Bulge is introduced, is locked with the housing. By this fastening method of the pressing device on the housing is the Assembly and disassembly of the pressing device particularly easy respectively.

Characterized in that after the concrete component has been drained in an advantageous manner se the pressing device can be removed from the housing again it is possible that a particularly inexpensive implementation of the Her position of a mass-spring system is possible. The press device will only needed to lift the concrete component and thereby to enable the assembly or disassembly of the spring component. by that this assembly or disassembly of the spring component is done the press is relieved, the concrete component on the spring direction or the subsoil and the pressing device again dismantled. The pressing device is then for another concrete component or another part of the first concrete component used to to assemble or disassemble the spring device there.

It is special for connecting the spring component to the concrete component advantageous if a closure plate of the spring component in the off the housing is moved. This is a positive  Get connection between the spring device and the concrete component ten, whereby the cushioning of the concrete component is possible.

Further advantages of the invention are in the following execution described examples.

Fig. 1 shows a section of a mass-spring system according to the invention, which is arranged for example in a tunnel. The tunnel tube itself is not shown for reasons of clarity. The lower area of the tunnel tube is poured with concrete 1 . On the concrete 1 forms for a concrete component 2, the surface on which it is stored.

In the present exemplary embodiment, the concrete component 2 essentially consists of a top plate 3 and a prefabricated plate 4 arranged thereon. The system shown here can be used as a fixed track for a rail-guided transport system. Vibration isolation and sound absorption are particularly important here, in order to enable quiet driving and also to avoid damage to the structure. Precast 4 and superstructure board 3 are conventionally connected to each other. The concrete component 2 forms the mass of the system.

A housing 5 for storage is arranged in the top plate 3 and possibly the prefabricated plate 4 . The housin 5 according to the invention is essentially tubular. The pipe extends from the top of the concrete component 2 to the subsurface, ie to the concrete 1 . Through the housing 5 , a spring device 6 and a pressing device 7 between the concrete component 2 and the concrete 1 are performed. Over the surface of the concrete component 2 , a plurality of Ge housings 5 are arranged to enable uniform storage of the concrete component 2 on the concrete 1 .

In Fig. 2 a more detailed representation of a Ge housing 5 according to the invention for a mass-spring system is shown. This is the embodiment of FIG. 1. The housing 5 has a tubular portion 10. The upper end of the tubular section 10 is open and extends essentially to the top of the concrete component 2 , so that the housing 5 is accessible from above. At the lower end of the tubular section 10 are two bulges 11 and 11 'angeord net. The bulges 11 and 11 'have wings 12 and 12 ' and a side wall 13 . The side wall 13 has a height which is higher than the height of a press 14 , but less than the height of an Ela stomerblockes 15 in the compressed state.

The storage is now produced in such a way that the housing 5 is placed on the substrate, ie on the concrete 1 from FIG. 1 or a separating film. The concrete component 2 is then created, the housing 5 being concreted into the concrete component 2 . The concrete component 2 has a height which corresponds essentially to the height of the side wall 13 and the tubular section 10 of the housing 5 .

After the concrete component 2 has hardened, the press 14 is inserted into the housing 5 through the tubular section 10 . In this state, the press 14 has a height which is less than the height of the side wall 13 . This makes it possible for the press 14 to be pushed laterally out of the tubular section 10 into the bulge 11 . The press 14 is then pressurized so that the height of the press 14 increases. The press 14 thus engages the Tragflä surface 12 of the bulge 11 and gradually lifts the concrete component 2 from the concrete 1 . This continues until the distance of the wing 12 'from the ground, ie from the concrete 1, is greater than the height of the elastomer block 15 in the unloaded state. This makes it possible for the elastomer block 15 to be inserted through the tubular section 10 into the housing 5 and laterally inserted into the bulge 11 '. Then the pressure is removed from the press 14 and the concrete component 2 is released . The concrete component 2 thus gradually lowers together with the housing 5 and the wing 12 'onto the elastomer block 15 and presses it together. The compression of the elastomer block 15 must not be so great that the side wall 13 touches the ground again, so that the concrete component can spring on the elastomer block 15 . By further pressure removal from the press 14 , the height of the press 14 is in turn reduced so that the press 14 can be brought into the region of the tubular section 10 and removed therefrom.

In order to avoid migration of the elastomer block 15 in the direction of the housing 5 during operation, a displacement lock 29 is provided. In the illustrated embodiment, this anti-displacement device 29 is a projection in the wing 12 '. Movements caused by vibrations past the anti-shift device must largely be excluded. Alternatively, the displacement lock can be obtained by an extension of the housing 5 beyond the wings 12 , 12 'or by egg nen use, for example a pipe socket, which is left in the housing 5 when the press 14 has been removed.

By a plurality of housings 5 , which is distributed along a large Be clay component 2 , an optimal suspension of the entire Be clay component 2 is achieved.

In a modification of this embodiment, it is possible in a not shown Darge that only a bulge 11 on the Ge housing 5 is provided. By mixing the housing 5 , as shown in Fig. 2 and the housing 5 with only one bulge, it may be sufficient for the presses 14 to be inserted into individual housings 5 provided with two bulges 11 and thus also into the concrete component Lift 2 recessed housing 5 with only one bulge 11 . An elastomer block 15 can then likewise be introduced into these housings 5 , which have been raised in this way.

In Fig. 3, another embodiment of the present invention is shown in a section. At the lower end of the tubular section 10 from the housing 5 , three bulges 11 are arranged, where only one bulge 11 is visible in the present illustration. Each of the bulges 11 is connected to a channel 16 with the upper end of the tubular section 10 . A slide washer 19 and a closure plate 20 are arranged on the elastomer block 15 . The closure plate 20 has projections 21 which correspond to the channels 16 and the bulges 11 .

When the concrete component 2 is raised, the elastomer block 15 is first inserted into the tubular section 10 of the housing 5 . The slide disc 19 arranged thereon is advantageously greased in order to allow the closure plate 20 to rotate with respect to the elastomer block 15 . After the sliding disc 19 , the closure plate 20 is inserted into the tubular section 10 of the housing 5 . The projections 21 are guided down along the channels 16 until the closure plate 20 rests on the sliding disk 19 . The housing 5 and the associated concrete component 2 must have a height with respect to the sub base, which now allows twisting of the United closure plate 20 within the bulges 11 . This means that the height of the unloaded elastomer block 15 , the sliding washer 19 and the closure 20 must be less than the distance of the support surface 12 from the ground. Now it is possible to rotate the projections 21 of the closure plate 20 from the channels 16 into the bulge 11 . After the concrete component 2 and thus the supporting surface 12 have sunk onto the projections 21 of the closure plate 20 , the elastomer block 15 is loaded and ensures the elastic suspension of the concrete component 2 . To rotate the closure plate 20 , these handles 22 , which can be attacked by an assembly tool, not shown, for simply rotating the closure plate 20 with its projections 21 into the bulges 11 .

Fig. 4 shows a plan view of the embodiment of FIG. 3. From this it can be seen that the bulges 11 and the channels 16 are evenly arranged on the circumference of the tubular portion 10 . By turning the handle 22, the projections 21 of the Ver circuit plate 20 with its protrusions 21 into the recesses 11 ge rotates, whereby a form-fitting transmission of force from the concrete part 2 via the bearing surfaces 12 and the shutter plate is introduced into the elastomeric block 15 20, when the concrete component 2 is lowered.

In Fig. 5 is a modified embodiment of the housing 5 in Fig. 3 and 4. With the embodiment of FIG. 5 is in addition to the Fe 2 countries of the concrete member and the lifting of the concrete component 2 possible. For this purpose, the housing 5 has, in addition to the lower bulge 11, further bulges 11 '. The bulges 11 ′, which are designed like the bulge 11 , serve to engage the press 14 .

In the housing 5 , which is poured into the concrete component 2 , and which is initially still on the concrete 1 as a base, the elastomer block 15 is first guided through the tubular section 10 . Subsequently, as already described, the slide plate 19 and the closure plate 20 with the projections 21 in the tubular section 10 and the channels 16 are placed on the elastomer block 15 . The height of the elastomer block 15 together with the sliding washer 19 and the closure plate 20 is at this time even greater than the distance of the wings 12 from the ground. Rotation of the projections 21 from the channels 16 into the bulges 11 is therefore not yet possible.

The press 14 is placed on the closure plate 20 . A further closure plate 23 is placed on the press 14 in the tubular section 10 and through the channels 16 . The closure plate 23 has, in the same way as with the closure plate 20, projections 24 which correspond to the channels 16 . The press 14 is in the initial state at a minimal height, so that the entire height from the bottom of the elastomer block 15 to the top of the closure plate 23 is such that the projections 24 can be inserted into the further bulges 11 '. This insertion is done by rotating the upper circuit board 23 on the handles 22nd Now the press 14 is pressurized so that its height increases. As a result, the Be claybauteil 2 is raised together with the housing 5 via the projections 24 and the wings 12 '.

By extending the press 14 , the wings 12 above the ground are raised so far that the distance of the wings 12 from the ground is greater than the height of the elastomer block 15 , the sliding disc 19 and the closure plate 20th Then, using a device, not shown, through the upper closure plate 23 and the press 14 , the lower closure plate 20 is rotated so that the projections 21 engage in the bulges 11 . In reaching this condition, the pressure can be released from the press 14 again, whereby the concrete component 2 rests on the housing 5 and the support surfaces 12 on the elastomer block 15 and is elastically supported. The press 14 is then relieved, so that the upper closure plate 23 can be rotated back so far that the projections GE 24 are arranged in the channels 16 . In this state, the upper closure plate 23 and the press 14 can be removed upwards from the tubular part 10 of the housing 5 .

In concrete components 2 in which a multiplicity of housings 5 are arranged, it is usually sufficient if individual housings 5 according to the embodiment in FIG. 5 and other housings 5 with the embodiment according to FIG. 3 are used. A press 14 does not have to be provided at each bearing point in order to raise the concrete component 2 . This would only be necessary for extremely heavy concrete components 2 .

FIG. 6 shows a further exemplary embodiment of the invention, which is similar to the embodiment according to FIG. 2. The housing 5 has a recess 31 . The recess 31 runs along the tubular section 10 from the upper end of the housing 5 to the Tragflä surface 12th In the recess 31 , the hydraulic hoses for operation of the press 14 can be arranged so that enough space remains in the housing 5 to be able to insert the spring elements through the housing 5 .

A carrier 30 , which is preferably welded, is arranged on the supporting surface 12 '. About the carrier 30 there is a very advantageous force introduction of the mass into the spring system. There is also no fear of the device breaking out of the concrete of the mass system.

The present invention is not limited to the illustrated embodiment games limited. Other designs are also possible, with wel Chen bulges are provided in the housing for engagement at least the spring device, and which advantageously one have provided additional bulge for engaging a press direction. The housing can also be square, for example or have a rectangular cross section, whereby the spring element the supply lines for the press can also be easily passed. The details of the individual versions can also be related to each other be combined.
