  • the sealing device according to DE-GM 83 35 231 tries to remedy the disadvantage of the hose body becoming blocked by introducing a non-woven material between the support body in the form of a helical spring and the outer network-like hose, which material is permeable to liquid but impermeable to fine concrete particles .
  • sealing medium is pressed directly into the beginning or end of the hose.
  • the start and end of the hose must be freely accessible from the outside after completion of the concreting measures in the joint area.
  • sealing medium can be introduced into sealing devices, in particular of the proposed type, in a simple, safe and inexpensive manner.
  • the proposed sealing device is completely detached from the previous use of hose-like sealing devices and suggests the use of a profile which is open in cross-section and is hood-shaped.
  • the profile is mounted with the free longitudinal edges of its side areas or side walls seated on the concrete surface, so that the free passage or flow channel is formed between the profile and the concrete surface, the sealing medium between the free longitudinal edges of the profile and the concrete surface in the joint area can leak.
  • profiles can be produced quickly and inexpensively by injection or extrusion and can be laid in a simple manner will.
  • silicates or hardening one- or multi-component plastics in liquid consistency are used as the sealing medium.
  • Synthetic resin in particular 2-component acrylic resin, is also used as a sealing medium, as are bentonite and / or cement mixtures.
  • the profile seen in cross section, is a U-shaped profile with a top wall and two side walls extending vertically therefrom.
  • the stackability of the profiles during storage can be improved in that the profiles have a trapezoidal or arched cross section.
  • An advantageous fastening of the profile is carried out by one or more screws, pins or nails, which encompass the transverse axis of the profile and encase it in the concrete.
  • the fastening of the profiles can preferably be increased in that the screw or the nail is supported by their heads, preferably via a washer, on the ceiling area or the ceiling wall of the profile, with the shaft reaching through a hole in the ceiling wall and into the concrete surface , if necessary, enclose in a dowel inserted therein.
  • a quick assembly of the profile is advantageously possible by shooting in the pin or the nail.
  • Supporting the ceiling wall is made possible by clamping the ceiling wall between the head and the shaft.

  • the profiles can also be attached to the concrete surface in the area of the web surface using suitable holding means.
  • the interior of the profile is filled with an open through-pored plastic foam (filter foam), the sealing medium in the flow channel being conductive through the through-pores of the plastic foam.
  • the plastic foam also supports the cross-sectional shape of the profile and ensures that the consumption of the sealing medium used is significantly reduced.
  • the plastic foam is chosen so that it has enough large and large passage pores to prevent the sealing medium from entering not to hinder and even prevent.
  • the interior of the profile can also be foamed with plastic foam or a plastic foam strip can be fitted into the interior.
  • the interior can be filled quickly and inexpensively with the plastic foam.
  • the plastic foam or the plastic foam strip advantageously has a protrusion beyond the longitudinal edges of the profiles. This protrusion ensures an enlarged cross section of the sealant from the profile.
  • a free passage channel is provided in the longitudinal direction of the profile below the ceiling wall with a bottom wall arranged approximately in the middle of the height of the side walls, which has a longitudinal slot or similar passages, the flow channel being filled with plastic foam below the bottom wall.
  • This configuration of the profile forms a free flow channel in which the sealing medium can initially enter and distribute unhindered, and then exit through the longitudinal cut into the plastic foam and from there into the joint area.
  • the passage channel can preferably also be formed in that a groove running in the longitudinal direction of the profile is arranged in the inner surface of the profile facing the flow channel, preferably in the inner surface of the ceiling wall.
  • connecting elements having the same cross-sectional shape of the profiles, preferably also made of plastic, are provided. With the help of such connecting elements, the profiles can be placed in any direction on the concrete surface che be arranged.
  • the connecting elements are preferably straight connecting pieces, flat corner angles, upright corner angles, T-pieces or crossing pieces. With the help of the proposed connecting elements, the most important changes in direction can be made when laying the profiles.
  • the connecting elements can be slipped onto the profiles and are preferably held thereon in a positive and non-positive manner.
  • the connection of the individual profiles via the connecting elements is thus carried out in a simple manner and the proposed connection ensures that no sealing medium can emerge from the profiles in the joint area.
  • the connecting elements can advantageously be screwed onto the concrete surface together with the profiles. Thus, only a bracket for profile and connecting element must be used at the joint.
  • an impermeable adhesive tape is provided at the joints to prevent cement slurries and other particles from entering the profiles in the joint area during the concreting process and on the other hand the sealing medium escaping from the ceiling and side wall area. since it is actually not needed there.
  • the adhesive tape is applied in the ceiling and side wall area of the joint and can also end before the free longitudinal edges are closed, since increased emergence in the lower area of the side walls may well be desirable.
  • the butt joints can preferably also be welded.
  • the profile or the connecting elements for injecting the sealing medium have a connection, in particular in the form of a tube or a non-porous hose, which with its free end is arranged outside the joint area or a formwork. Accordingly, certain elements of the sealing device can already be provided with such a connection, so that such a connection point no longer has to be created on site.
  • the method for introducing the sealing medium described later can be used with particular advantage.
  • the profiles or connecting elements in the side walls have notches with their corners or notch tips on the ceiling wall or just before the ceiling wall end up.
  • the profiles or connecting elements are bent around their longitudinal axis and fastened on a curved concrete surface or on an arched or circular body, for example a pipe, the side edges of the notches abutting one another and the notches thus being closed, if the longitudinal edges of the side walls lie on the concrete surface or the body.
  • the sealing device can be arranged not only on curved concrete surfaces, but even on curved or circular bodies. It is important that the notches are completely closed when the longitudinal edges lie against the concrete surface or the surface of the corresponding body.
  • the notches can also be sealed with an adhesive tape.
  • An advantageous way of fastening the profile is that the profile and / or a connecting elements are held by a tubular clamp-shaped bracket.

  • the fact that the sealing medium A high degree of sealing in the area of the concrete joint is achieved not only in the area of the contact area of the foam tape in the joint area, but also from its side and ceiling area.
  • a hose-like hollow body can be provided as the inlet opening for the sealing medium, for example, which is inserted into the body at one end and is arranged at the other end outside the second concreting section or its formwork.
  • the method for introducing the sealing medium described later can be used with particular advantage.
  • the foam or the foam tape used on the one hand has sufficient porosity for the passage of the sealing medium and on the other hand is of a consistency that largely avoids compression of the foam or the foam tape by the applied concrete.
  • silicates or hardening single- or multi-component plastic in liquid consistency are used as sealing medium.
  • Synthetic resin, in particular 2-component acrylic resin, is also used as a sealing medium, as are bentonite and / or cement mixtures.
  • the body is advantageously fastened to the concrete surface by means of one or more pins, screws or nails which extend transversely to its longitudinal axis and surround the concrete and preferably have washers.
  • the introduction of dowels in the concrete surface or by a predetermined setting of shooting devices ensures that the above-mentioned holding means only engage in the concrete surface to such an extent that their head region lies approximately in a plane with the surface of the body after the introduction.
  • the desired end position of the pins, screws or nails can be achieved by using tubular spacers which encompass the holding means, the length of the spacers being approximately the cross-sectional height of the body corresponds. The spacer then ensures that the holding means do not penetrate too deep into the body.
  • Another preferred mounting of the body can also be carried out by mounting profiles comprising it, which are mounted on the concrete surface.
  • the support profiles can be metal or plastic straps that completely or partially encompass the cross-sectional circumference of the body, the support profiles being arranged with a free end on the concrete surface, so that the support device holds or clamps the body on the concrete surface without significantly reducing the cross section of the body at the bus stop.
  • a continuous recess running in the longitudinal direction can be provided in the cross-sectional interior of the body and serves as a through-channel for the sealing medium.
  • the through-channel is first filled and then the sealing medium penetrates the body until it emerges into the concrete area, closing off the existing joints.
  • connection of at least two bodies on the abutting edges of the same is advantageously carried out by the same cross-sectional shape and made of the same material connecting elements.
  • These connecting elements can be straight connecting pieces, flat corner brackets, upright corner brackets, T-pieces or crossing pieces, so that changes in direction can be easily taken into account when laying the body.
  • An adhesive tape is preferably provided to connect the bodies to one another or the body to the connecting elements at the joints.
  • the tape is used primarily for Securing the position of the body and can preferably be attached only on the side of the body facing away from the concrete surface and in the upper region of the side parts of the body, so that sufficient sealing material can escape even at the joint, despite adhesive tape.
  • V-shaped, notch-like incisions are provided, extending over their entire cross-sectional width, the notch tips slightly below that Cross-sectional height of the body or the connecting elements are arranged.
  • the notch-like incisions should therefore only be made to such an extent that the body still forms a coherent body.
  • the bodies or fasteners are bent about their longitudinal axis and secured on a curved concrete surface or on an arc or circular element, for example a pipe, the side edge surfaces of the notches abutting one another and the notches thus being closed when the underside of the body is on the Concrete surface or the element.
  • the foam strips can also follow curved or curved courses.
  • the bodies or connecting elements are also advantageously possible to bend the bodies or connecting elements about their longitudinal axis in order to fix them on a curved concrete surface or on an arcuate or circular element, for example a pipe, without providing notch-like incisions.
  • the body consisting of the foam or filter foam will compress in the area facing the curved or curved surface, but this compression does not prevent the sealing material from escaping. This is because the material intended for the body is of such a nature is that even with a stronger compression of the material, the passage pores required for the passage of the sealing medium are still present.
  • the bodies and / or connecting elements are advantageously held on the circular element with an endless rubber band, in that the rubber band is stretched over the top of the bodies or connecting elements.
  • This simple and quick way of fastening the body and / or the connecting elements ensures a firm fit on circular or curved elements without having to use other mounting means.
  • the rubber bands can preferably have a cross-sectional width that is smaller or substantially smaller than the cross-sectional width of the body or bodies, so that leakage of the sealing medium is also not significantly hindered on the top of the body.
  • the body has on its top surface facing away from the concrete surface and its side surfaces a type of coating or coating of harder foam, which is preferably impermeable to the sealing medium, the coating in the area of the Side surfaces preferably end in front of the underside or standing surface of the body, so that the through-pored foam or filter foam in the lower side areas is without the coating.
  • the body should therefore have a second, outer layer by means of the additional coating to be arranged in parts of its side areas and above all on its surface, which on the one hand represents a support effect for the body and on the other hand a leakage of the sealing medium injected into the body from the Prevents areas that have the coating.
  • the sealing medium should in particular seal the joint area, ie the area of the base of the body. Because the coating in the side areas is not up to the footprint of the body is pulled down, but ends in front of this and thus in front of the concrete surface, a sufficiently large exit surface for the sealing medium is created in the lower side areas in the standing area of the body.
  • the coating can be applied subsequently to the body or can be produced together with the body. It does not matter whether the body, seen in cross section, has a linear side edge or a crack due to the application of the coating.
  • the foam or the filter foam of the body is of a material which prevents the body from being compressed too much, even at high pressures, so that there is always a sufficiently large outlet space for the sealing medium.
  • the body according to the invention consisting of foam or foam tape, is advantageously used for sealing a groundwater relief connection.
  • Groundwater relief ports which penetrate floor slabs, for example, with the groundwater level above the level of the floor slab, are wrapped or wrapped around the body at the base plate / discharge port connection point, so that after the sealing medium has been introduced into the body, a secure seal against rising groundwater at the aforementioned connection point is guaranteed.
  • the proposed body can advantageously be used to seal a joint area between a body, for example a pipe, and a concrete section, in particular if liquids are constantly or occasionally present on one side of the concrete section.
  • a body for example a pipe
  • a concrete section in particular if liquids are constantly or occasionally present on one side of the concrete section.
  • water-filled concrete pools in the concrete walls have pipe openings or other devices, such as headlights or the like, whereby the joint area between the concrete walls and the bodies used therein must be carefully sealed in order to prevent water from penetrating into this area with the proposed Body and a subsequent injection of the sealant can be done safely and reliably.
  • the proposed body can be used to seal a connection point between two pipes, even with a pipe socket connection point.
  • the body is arranged in the area of the gap between the two pipes connected to one another by being placed around this area and forming a ring around the connection point, as in the relief connection. After the sealing medium has been introduced into the body, the connection point is secured in such a way that any escaping liquid can be safely retained from the connection point.
  • An essential basic idea here is the knowledge that one or more external connections for introducing the sealing medium, which are arranged outside the second concreting section or the formwork, can be dispensed with, i.e. the sealing device without a connection to the outside in the joint area between the two concreting sections is arranged.
  • All previously known sealing devices and in particular the sealing devices according to claims 1 and 33 can be filled with a sealing medium by a subsequent connection between an outside of the concrete or the second concreting section and the sealing devices.
  • the sealing medium is e.g. for silicates or hardening one- or multi-component plastics in liquid or compressible consistency.
  • Synthetic resin, in particular 2-component acrylic resin can also be used as a sealing medium, as can bentonite and / or cement mixtures.
  • connection is made, for example, in particular by drilling into the hardened concrete between an outer sieve te of the concrete and the sealing devices. It goes without saying that the bore must be made so far that the flow channel or the passage of the sealing device is accessible.
  • the sealing medium is then introduced or pressed in through the connection or the borehole.
  • a further connection to the sealing device is advantageously created, through which the air can escape during the press-in process and which also serves as a control point as to whether the sealing medium has also penetrated the entire sealing device. It is also conceivable to create a larger number of such connections and then to seal them when the sealing medium emerges from the connection points.
  • connection points serving as control points should be arranged at the beginning or at the end of the joint in order to check that the sealing medium also extends into the end regions of the sealing device has penetrated.
  • connection can be made horizontally or from obliquely above or obliquely below in the direction of the sealing device.
  • the connection points are preferably made at predetermined positions, it being possible to determine beforehand at what height or at what angle and above all how long the connection point must be created, in order to ensure that the sealing device is also hit or drilled in the desired manner .
  • the proposed method for introducing the sealing medium into sealing devices prevents the formwork from having one or more openings for previously laid connection openings or connecting pieces. It also prevents these previously created connection points from being torn or destroyed during formwork or concreting.
  • the load-bearing capacity or safety of the pierced concrete is not reduced by the arrangement of several connection points.
  • the plastic profile 2 is mounted on the concrete surface 1 such that the free longitudinal edges 5 of the side walls 3 sit on the concrete surface 1, so that a flow channel 6 between the concrete surface che 1 and the profile 2 is formed.
  • the profile 2 can be fastened to the concrete surface 1 using brackets or the like.
  • a simple screw connection is preferably provided, in which a screw 7 is supported with its screw head 8, possibly via a washer (not shown), on the ceiling wall 4, with its shaft engages through a hole in the ceiling wall 4 and e.g. is screwed into a dowel arranged in the concrete.
