Definitions

  • the present invention relates to a press seal with a clamping device, which has two pressure elements and clamping elements, and arranged between the pressure elements filler of elastic deformable material which is compressible via flat contact surfaces of the pressure elements by the clamping device in a pressing direction and thereby extends perpendicular to the pressing direction to create a tight fit between two components over opposing sealing surfaces, as well as a seal assembly and construction with precast elements using the compression seal and the use of such a press seal.
  • prefabricated elements In the construction of structures made of prefabricated elements, there is always the problem of ensuring a sufficiently secure watertight sealing of the joints.
  • the prefabricated elements are usually finished part walls of any kind, be it for the construction of buildings, structures for flood protection, protective walls in nuclear facilities, tunneling, etc., but also in these construction projects existing other precast elements such as columns or support elements and the like.
  • joint tapes or joint plates which are used to seal movement and construction joints in waterproof concrete structures. These joint plates are embedded in both the foundation and in the precast element and thereby prevent the ingress of moisture.
  • elastic jointing materials are introduced. These may age over time and become leaky and may not provide a permanent, secure seal in certain applications.
  • the present invention is therefore based on the object to suggest a possibility of sealing between prefabricated components with each other, which allow particularly durable and thereby the use of precast elements in particularly critical applications.
  • a compression seal is proposed, the filler body in cross-section polygonal with at least two mutually parallel planes, the pressure surfaces of the pressure elements facing longitudinal sides are provided with at least two opposite sealing surfaces between the pressure surfaces.
  • the pressure surfaces are rectangular in plan view, so that the filler expands only at the periphery of the filler perpendicular to the pressing direction.
  • the filler is thus a solid structure with a longitudinal extent, wherein the cross section is usually rectangular and the shape of the filler is cuboid, however, depending on the application, the training in cross section can be designed in such a way that in any case a compressive force can be applied by the clamping elements on the pressure surfaces on adjusted flat longitudinal sides.
  • the sealing sides of the shaped body can also be adapted in shape as required by the arrangement of prefabricated components in which the press seal is used.
  • the filling element expands exclusively in the outer circumferential direction and thus enables a secure sealing with its sealing sides. If it is ensured that the press seal remains accessible, a later tightening or replacement of the press seal is possible with decreasing sealing performance or aging.
  • the filler body does not have to consist of one piece, but may also have a plurality of filler elements, which are preferably arranged between the pressure elements so that in each case a Gueniaelement rests with its entire surface on the pressure surface.
  • the shapes of the Artireieri may be different depending on the application, at least in cross section.
  • the filler is often rectangular, but in the simplest form trapezoidal or have any other conceivable configuration.
  • the pressure surfaces are rectangular in plan view, but this does not exclude that they are curved or bent, depending on the application.
  • the pressure surfaces are generally flat, but may also have projections in the form of tips, which, if necessary, penetrate into the filler.
  • the clamping elements are screw means, in particular carriage bolts, accessible from one side of the clamping device for generating and adjusting the pressing force.
  • the clamping element and the filling body at least two clamping elements are provided. Due to the longitudinal extent of the clamping element, it is thus possible to realize a plurality of different lengths with a corresponding number of clamping means. This also allows the juxtaposition of several such clamping elements, for example in a channel and the subsequent replacement of the press seals, for example due to aging, provided that the channel remains accessible at least from one side.
  • This can for example be a common in the sealing of concrete structures joint plate.
  • the sealing arrangement according to the invention for prefabricated elements of buildings comprises in each case in the sealing side a channel along the prefabricated element which forms a receiving space with the channel of the other prefabricated element.
  • This receiving space thus extends along the height of the precast element and serves to receive a seal extending in the longitudinal direction of the receiving space in the form of at least one of the above-described press seals.
  • this can be a press seal extending in the longitudinal direction or even a plurality of press seals which also press against one another, since these expand on the circumference as a result of the clamping force, as described above.
  • the packing of the press seal are sealingly against the precast elements or can be brought by conditioning, the clamping elements of at least one clamping element from one side of the structure can be braced.
  • the latter means that between the precast elements at least on one side of the wall formed remains a gap which is sufficient to with a tool, the clamping elements clamp and thus to realize the seal between the precast elements.
  • This arrangement has the particularly great advantage that, for example, in buildings with high potential for risk in the event of leakage for the population, such as flood protection walls or walls at nuclear power plants, a check of the tightness and possibly a retightening of the press seals or replacement of a press seal is possible.
  • the receiving space extending in the longitudinal direction of the sealing side remains accessible even after filling with the press seal or seals, in order to be able to replace it if necessary.
  • the at least one press seal includes a joint plate arranged in a base foundation for the prefabricated elements along the support surface of the precast elements extending on the foundation between two packing elements.
  • a joint plate arranged in a base foundation for the prefabricated elements along the support surface of the precast elements extending on the foundation between two packing elements.
  • an above-mentioned press seal with two approximately equal size packing is used, wherein the distance of the clamping elements is formed so that the joint plate fits between them.
  • the installation of such a press seal is of course prior to concreting the ground foundation after the precast elements have been placed on the prepared reinforcement.
  • the press seal enclosing the joint sheet has to project out of the receiving space and projects into the foundation.
  • the seal is formed from the first press seal enclosing the joint plate and at least one further press seal arranged in the receiving space, in order to allow the above-mentioned later exchangeability with aging for the at least second press seal.
  • the first, the joint plate enclosing press seal is inevitably no longer interchangeable.
  • the pressure elements of the at least one further pressure seal preferably at least partially cover the filling body of the first pressure seal. In this area, the joint between the press seals is thereby additionally covered by the pressure elements on both sides of the filling body and achieved an additional seal and mechanical connection.
  • the pressure elements of the at least one further project beyond the filling of the at least one further press seal at least on one side. When using multiple press seals, this can be realized at each joint.
  • An inventive construction with prefabricated elements, which face each other with sealing sides, advantageously has a channel in each case in the sealing side along the finished part element, which forms a receiving space with the channel of the other prefabricated element and in which a seal extending in the longitudinal direction of the receiving space is arranged by at least one of the above-described press seal.
  • the filler is sealingly against the precast elements and the clamping elements are accessible from one side of the structure.
  • Under finished element in this sense, for example, straight or curved walls on the ground or on other walls, tunnel walls but also understood any connections, for example, between concrete columns and precast elements.
  • an already mentioned preferred structure may comprise precast elements on a foundation foundation, in which the seal encloses a joint plate projecting into the foundation. It is further preferred that the structure has a seal with a plurality of press seals, in particular when the seal encloses the joint plate, wherein particularly preferably the pressure elements of the subsequent further press seal at least partially cover the packing of the first, the joint plate enclosing press seal.
  • the interchangeability can be simplified by the use of multiple press seals.
  • the pressure seal enclosing the joint plate is inevitably not interchangeable, so that it is expedient to make it short and to connect one or more further pressure seals. Due to the overlap of the pressure elements additional tightness and mechanical stability can be achieved.
  • the object of the invention is also achieved by the use of at least one of the press seal described above in a building for sealing facing sealing sides of finished elements.
  • the invention thus opens up a new application possibility for precast components, since this eliminates the problem of tightness, in particular in flood protection, but also in other critical applications.
  • the ability to inspect the seal, re-tension and, if necessary, replace the seal, ensures a highly secure seal.
  • the in the FIGS. 1 and 2 press seal 1 shown has a clamping device 2, which consists of two pressure elements 3, 3 'and in this embodiment two clamping elements 4. Between the pressure element 3, 3 'is a packing with in the embodiment, two Rail Stressierin 5', 5 ", with their flat longitudinal sides 6 to the pressure surfaces 7 of the respective pressure element 3, 3 'on the one hand and against each other with the flat longitudinal sides 6' on the other Depending on the length of the press seal 1, there are either two or more clamping elements in the form of carriage bolts 4, which with their screw heads in usually corresponding, not shown square openings in the pressure element 3, preferably designed as a stainless steel plate, eino to a twisting during clamping on the other side of the pressure element 3 ', also preferably designed as a stainless steel plate to prevent FIG.
  • press seal 1 is in the FIGS. 3 to 5 shown, wherein in the FIGS. 3 to 5
  • the invention will be explained with reference to the structure of a structure 5 made of straight finished wall elements 9, 9 'as a precast element in conjunction with a joint plate 10.
  • the joint plate 10 can be omitted, so that here only press seals 1 with only one filler 5 can be used.
  • the great advantage of the invention is best seen.
  • FIG. 3 shows the upper press seal 1 'which is introduced from above in the unstressed state in the receiving space 11 and then clamped over the gap 13 between the prefabricated wall elements 9, 9'.
  • overlapping joint plates 14, 14 ' are indicated by dashed lines, which are enclosed by a press seal 1 of the seal 12 which is not visible in this view.
  • FIG. 4 shows the side view with a press seal 1, which includes the joint plate 14 and a subsequent significantly longer press seal 1 ', which in its full length in the FIG. 5 is shown.
  • the press seal 1 has two clamping elements 4, between which the joint plates 14, 14 'are arranged.
  • the press seal 1, for this purpose has two Guisson phenomenon 5 ', 5 ", as in the FIGS. 1 and 2 illustrated, while the much longer press seal 1 ', which extends to the region of the upper edge 15 of the finished wall elements 9, 9', only one filler 5 may have.
  • the pressure elements 3 of the upper press seal 1 ' cover the two-part filler 5 of the lower press seal 1, which includes the joint plate 14.
  • the joint between the two packing 5 of the upper compression seal 1 'and the lower compression seal 1 is covered by the pressure elements 3 of the upper compression seal 1' in this area and increases the sealing ability and mechanical distortion.
