Definitions

  • the invention relates to a device for sealing joints between two components, for. Concrete, consisting of a longitudinally extending, at least one injection cavity having, tubular Organ, whose wall with at least one slit-like exit slit for an injectable into the injection cavity sealing compound is provided and laterally the exit slit at least one parallel to the injection cavity extending compressible cavity is provided, wherein the injection cavity has a circular cross-section and the compressible cavity is circumferentially closed.
  • Devices for sealing joints between two components are, for example from the following patent 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 of circular cross-section. From each of these injection cavities goes out an arcuate outlet gap.
  • the core or support body This injection profile consists of a hard, elastically deformable, resistant plastic, whereas that of the exit slit and the respective associated injection cavity limited section, which is semicircular is recessed, each receives a sealing strip. Each of these sealing strips is in fitted the semicircular recess of the support body. These sealing strips are made of a compressible material.
  • Such injection profiles can properly perform their intended function, the expense of their However, production is not insignificant. There must be two for an injection profile Components made of different materials and subsequently to a united body.
  • Is the thigh exposed arranged forms under the pressure of the injection cavity Injected mass in the region of the outlet opening a longitudinal slot, over whose entire length of the sealant is pressed against the component, so that the profile in the area of its compressible cavities in the direction of the component is compressed.
  • several cavities as injection cavities, z. Two or three, whereas the rest of the cavities are more compressible Cavity is used.
  • the pressure to be built up in the injection cavities is very high, it can be up to over 100 bar and between the pump, this pressure has to build, and the device mentioned is to arrange a connector, over which the pressurized sealant from the pump can be introduced into the mentioned device.
  • a connector that the mentioned cross-sectional shape of the cavities is adaptable and mentioned can absorb high pressures, so far, however, does not exist, so that This previously known construction can not find an entrance into practice. in other embodiments of DE-OS 34 27 110 (Fig.
  • the devices of the type mentioned above is the compressible cavity in a central cross-sectional area and the injection cavity in a peripheral area arranged the tubular body, wherein the injection cavity has a circular cross-section and the exit slit is straight and on the side facing away from the compressible cavity from the circumference of the injection cavity emanates. Also in these embodiments is in the Injection cavities to be built up pressure high.
  • the object of the invention is an improved device of the aforementioned To provide type and according to the invention this succeeds in a device with the features according to claim 1. Thanks to this proposal can work with proven and practical Connectors provide the necessary connection between pump and device being constructed.
  • the device can be made entirely from a solid, resistant, flexible and non-compressible material be, and still can the exit gap for the exit of the sealant open when a reasonable pressure builds up in the injection cavity will or in turn close when the pressure in the injection cavity degraded and the excess sealant is sucked off.
  • FIGS. 1 to 6 show end views of various embodiments of the invention, wherein these embodiments substantially by the outer cross-sectional contour or by the number of each existing injection cavities differ.
  • the elongate, tubular member 1 of FIG. 1 has a circular Circumferential contour 2. Inside runs an injection cavity 3, which also has a Has circular cross section. Laterally this arranged in the middle cross-sectional area Injection cavity 3, the outer contour 2 adjacent, a circumferentially closed, compressible cavity 4, here an oval cross-section shows. The longitudinal extent of this oval cross-section is substantially in the radial direction of the tubular hurricane 1.
  • the compressible Cavity 4 extends parallel to the injection cavity 3.
  • the exit slit. 5 goes near that point from the circumference of the injection cavity 3, at the one imaginary straight line G1 intersects the circumference of the injection cavity 3, which the Central regions of the two cavities 3 and 4 connects.
  • the exit gap 5 follows at a distance of the peripheral contour of the compressible cavity 4.
  • the peripheral contour 2 of the hose-like hurricane 1 immediately adjacent Section of the exit slit 5 has a deviating from the straight course, small, hook-like curvature 6 on. This curvature only extends over a fraction of the total length of the exit slit 5 and is for example about 1/10 of its length.
  • An imaginary straight line G2 representing the inner mouth area of the exit slit 5 continues tangentially, which crosses the central areas The cavities 3 and 4 connecting straight G1 under about 90 degrees.
  • the distance between the exit slit 5 and circumferential contour of the compressible cavity substantially constant. It but is also conceivable and is within the scope of the invention, the course of the exit slit 5 so that the mentioned distance from the inside to the outside increases.
  • the device according to Fig. 1, and this also applies to the other embodiments of the invention has a homogeneous cross-section as far as the material is concerned.
  • she is made of a solid, elastically deformable, resistant and non-compressible Material manufactured to withstand the high external pressure without significant deformation can withstand the generated by the material piled up is when the device is used as intended.
  • the circumferentially closed, compressible cavity 4 ensures that the exit slit. 5 opens when in the injection cavity 3, a correspondingly high pressure on the Injecting sealant is constructed, or that the exit slit. 5 in turn closes when from the injection cavity 3, the excess Dust is removed.
  • the tubular organ can, as in such cases be known, wound with threads and braided.
  • the invention tubular organ can be produced in a single operation. There it does not require a braiding itself, the outer cross-sectional contour be designed arbitrarily.
