Definitions

  • the invention relates to a device for sealing joints between two components, for. B. made of concrete, consisting of a longitudinally extending, at least one injection cavity having a hose-like member, the wall of which is provided with at least one slot-like outlet gap for an injectable sealing compound and laterally of the arcuate outlet gap, at least one extending parallel to the injection cavity, compressible cavity is provided.
  • Devices for sealing joints between two components are known, for example, from the following property rights publications: DE-OS 41 40 616; DE-U-86 08 396; DE-U-94 02 078; EP-0 199 108 A1; EP-0 277 530 A1; CH 505 955 A; US 4 141 189.
  • the elongated organ with a circular cross-section has four injection cavities with a circular cross-section.
  • An arcuate outlet gap extends from each of these injection cavities.
  • the core or support body of this injection profile consists of a hard, elastically deformable, resistant plastic, whereas the section delimited by the outlet gap and the associated injection cavity, which is recessed in a semicircular shape, receives a sealing strip.
  • Each of these sealing strips is fitted into the semicircular recess in the support body.
  • These sealing strips are made of a compressible material. Injection profiles of this type can properly fulfill the function intended for them, but the outlay for their production is not insignificant.
  • two components have to be made of different materials and subsequently connected to form a single body.
  • the injection profile is designed in a cross shape, with legs that are angled in a clockwise direction at the ends of the cross beam, the ends of which can be connected to the adjacent cross beam or lie against it.
  • This profile shape creates four cavities, at least of which one forms the injection cavity and at least one other forms a compressible cavity.
  • the injection cavity is provided with an outlet opening which is created by a puncture.
  • a longitudinal slot forms under the pressure of the mass injected into the injection cavity in the area of the outlet opening, over the entire length of which the sealing compound is pressed against the component, so that the profile in the area of its compressible cavities is pressed together in the direction of the component becomes.
  • several cavities can be used as injection cavities, e.g. B. two or three are used, whereas the rest of the cavities is used as a compressible cavity.
  • This previously known construction is based on the idea that, instead of a sealing strip made of compressible material, the area adjacent to the outlet gap, which is here made of a solid, resistant and non-compressible material, can be deformed under pressure, so that if necessary, under pressure the injected sealant opens the outlet gap and the sealant can open the way to the outside, on the other hand the outlet gap closes again as soon as the pressure in the injection cavity is released.
  • the cavities mentioned have a drop-shaped cross section and, moreover, are also somewhat sickle-shaped.
  • the pressure to be built up in the injection cavities is very high, it can be up to over 100 bar and a connection piece is to be arranged between the pump which has to build up this pressure and the above-mentioned device, via which the pressurized sealant from the pump into the mentioned Device can be introduced.
  • a connector which can be adapted to the cross-sectional shape of the cavities and which can absorb the high pressures mentioned has not yet been available, so that this previously known construction has not been able to find its way into practice.
  • the invention now proposes that the injection cavity has a circular cross section in a manner known per se and the compressible cavity is circumferentially closed and the outlet gap at or near that point on the circumference of the Injection cavity starts, at which a straight line connecting the central regions of the two cavities intersects the circumference of the injection cavity. Thanks to this proposal, the necessary connection can be established with proven and practical connectors between the pump and the device.
  • the device can be made entirely of a solid, resistant, flexible and non-compressible material, and yet the outlet gap for the sealant outlet can open when an appropriate pressure is built up in the injection cavity or close again when in the injection cavity the pressure is released and the excess sealant is sucked off.
  • FIG. 1 to 6 show end views of various embodiments of the invention, these embodiments differing essentially by the outer cross-sectional contour or by the number of injection cavities present in each case.
  • the elongated, tubular member 1 according to FIG. 1 has a circular circumferential contour 2. Inside is an injection cavity 3, which also has a circular cross section. To the side of this injection cavity 3, which is arranged in the middle cross-sectional area, is a circumferentially closed, compressible cavity 4, which is adjacent to the outer contour 2 and which here shows an oval cross section. The longitudinal extent of this oval cross-section extends essentially in the radial direction of the tubular member 1.
  • the compressible cavity 4 extends parallel to the injection cavity 3.
  • the exit gap 5 starts near the point from the circumference of the injection cavity 3, at which an imaginary straight line G1 defines the circumference of the Injection cavity 3 intersects, which connects the central regions of the two cavities 3 and 4.
  • the outlet gap 5 follows at least part of its length at a distance from the circumferential contour of the compressible cavity 4.
  • the section of the outlet gap 5 which is directly adjacent to the circumferential contour 2 of the tubular member 1 has a small, hook-like curvature 6 which deviates from the straight course. This curvature extends only over a fraction of the entire length of the outlet gap 5 and is, for example, approximately 1/10 of its length.
  • An imaginary straight line G2 which continues the inner mouth area of the outlet gap 5, crosses the straight line G1 connecting the central areas of the cavities 3 and 4 at approximately 90 degrees.
  • the distance between the exit gap 5 and the circumferential contour is essentially constant. It is also conceivable and within the scope of the invention to design the course of the outlet gap 5 so that the aforementioned distance increases from the inside to the outside.
  • the device according to FIG. 1, and this also applies to the other embodiments of the invention, has a homogeneous cross section in terms of the material. It is made of a solid, elastically deformable, resistant and non-compressible material that can withstand the high external pressure without significant deformation, which is generated by the heaped-up material when the device is used as intended.
  • the circumferentially closed, compressible cavity 4 ensures that the outlet gap 5 opens when a correspondingly high pressure is built up in the injection cavity 3 via the sealing compound to be injected, or that the outlet gap 5 closes again when the excess sealing compound from the injection cavity 3 is subtracted.
  • the tube-like organ can be wound and braided with threads.
  • the tubular organ according to the invention can be produced in a single operation. Since braiding per se is not required, the outer cross-sectional contour can be designed as desired.
