Definitions

  • the invention relates to an injection hose for construction joints on concrete structures, with a base body which comprises a flexible material, such as rubber or plastic, and surrounds a passage channel, which has radial openings along its length for the discharge of injection liquid from the passage channel, and along its length in the area of the radial openings has a recess extending over its length for receiving a strip covering the openings from material that is compressible under the pressure of the injection liquid, and with a tube of liquid-permeable material surrounding the base body and the strip.
  • a base body which comprises a flexible material, such as rubber or plastic, and surrounds a passage channel, which has radial openings along its length for the discharge of injection liquid from the passage channel, and along its length in the area of the radial openings has a recess extending over its length for receiving a strip covering the openings from material that is compressible under the pressure of the injection liquid, and with a tube of liquid-permeable material surrounding the base body and the strip.
  • an injection hose which has an inner support body having a liquid-permeable wall, a first liquid-permeable network-like hose enveloping this support body and a second liquid-permeable, network-like hose enveloping this first hose, wherein between the In both of the above-mentioned network-like hoses, a tubular fleece is provided, which should be impermeable from outside to inside for concrete particles, but should be permeable from inside to outside for sealants.
  • a support body-free hose with high stability which has a large number of openings in its wall.
  • a hose-like filter layer is arranged between this inner hose and an outer network-like hose.
  • the openings for the concrete sealant of the inner hose are arranged, for example, in four rows running parallel to the longitudinal axis of the hose, which are at equal distances from one another.
  • Injection hoses of this type are complex to manufacture and not always reliable in use because of the need for the special selection of the network-like hoses and tubular nonwovens, since it is necessary to match the network-like hoses and the tubular nonwoven to the concrete particles and the sealant used.
  • the known injection hoses are also often difficult to install due to excessive rigidity and are easily damaged in rough construction site operation, which prevents the uniform distribution of the injection liquid over the entire length of the injection hose.
  • an injection hose of the type mentioned at the outset is proposed in DE-U 8 425 518.8, in which the only radial opening for the outlet of the injection liquid is designed as a slot which extends over the entire length of the base body and in which the edges of the Strip are rounded and received in corresponding recesses in the recess.
  • the strip has a spring which engages in the slot.
  • the object of the invention is to further develop an injection hose of the type mentioned at the outset in such a way that it is easier to manufacture and handle, and the injection liquid reaches the desired locations reliably and uniformly.
  • the solution according to the invention creates an injection hose which is simple to manufacture and handle and in which it is ensured that the injection liquid can be fed to any desired location of a construction joint without any problems.
  • An embodiment of the invention which is particularly expedient in terms of manufacture provides that the depressions and the associated strips have straight-sided side walls which, in particular (with respect to a certain depression) run at an acute angle to one another.
  • This embodiment is also very expedient, in particular for manufacturing reasons, because the base body and strips can be easily extruded and the strips can simply be inserted into their recess.
  • the width of the base of the depressions is only slightly larger than the diameter of the radial openings in the relevant direction.
  • a diameter of the openings of approximately 3 mm is expediently provided, while the distance between the openings is advantageously approximately 2 cm and the diameter of the passage is approximately 6 mm.
  • the radial openings are designed as holes or slots arranged in longitudinal rows, the longitudinal rows being distributed at equal angular intervals over the circumference of the base body.
  • the injection hose advantageously consists only of a base body and a corresponding number of strips provided in the depressions distributed around the circumference. A correspondingly different number of rows of holes and associated strips can be provided for different applications.
  • the base body consists of polyvinyl chloride, that the surrounding hose is made of a bobbin lace fabric and that the strips covering the openings are advantageously made of foam rubber, foam rubber or neoprene, since this makes it easy to set the required compressibility.
  • the single figure illustrates in cross section an injection hose having the invention.
  • the injection hose 1 consists of a base body 2, which has an essentially hollow cylindrical wall and thereby forms a continuous central cylindrical passage 3.
  • the injection liquid is supplied to one or both ends of the injection hose 1 or, if appropriate, also with connections provided in between, in order to distribute it over the length of the construction joints to be sealed.
  • Four depressions 5, 6, 7 and 8 are provided over the circumference of the base body 2 at equal angular intervals and extend over the length of the base body 2. Radially extending openings 9, 10, 11 and 12 are provided for the flow connection of the passage 3 and the depressions 5, 6, 7, 8, which on the one hand open into the passage 3 and on the other hand into the depressions 5, 6, 7 and 8.
  • the recesses 5, 6, 7 and 8 are of identical design for reasons of symmetry, so that only the recess 5 need be described in more detail here.
  • the recess 5 has two side walls 13, 14, which are arranged at an angle converging inwards towards one another, so that there is an extension to the outer edge of the base body 2.
  • the angle formed by the side walls 13, 14 is acute.
  • the base 15 of the recess 5 is not significantly wider than the diameter of the associated openings 9.
  • the bases 15 of the recesses 5, 6, 7 and 8 are rounded and lie on a common (imaginary) cylindrical surface.
  • Strips 16, 17, 18 and 19 are arranged in the depressions 5, 6, 7 and 8, the shape of which is adapted to the shape of the depressions 5, 6, 7 and 8. They lie flush with the outer circumference of the projections of the base body 2 that have remained between the depressions 5, 6, 7 and 8.
  • the distance between the openings 9, 10, 11 and 12 is expediently about 2 cm in the axial direction, the diameter of the passage 3 is expediently about 6 mm, while the diameter of the openings 9, 10, 11 and 12 is about 3 mm.
  • the depth of the depressions 5, 6, 7 and 8 is also expediently 3 mm.
  • the openings 9, 10, 11 and 12, viewed in the axial direction, can be offset with respect to the openings in the adjacent longitudinal row in order to even out the injection liquid outlet.
  • Polyvinyl chloride is advantageous as the material for the base body 2, while the strips 16, 17, 18 and 19 consist of foam rubber, foam rubber or neoprene because of the desired compressibility.
  • the base body 2 and the strips 16, 17, 18 and 19 arranged in the depressions 5, 6, 7 and 8, which essentially end with the outer circumference of the base body 2, are surrounded by a tube 20 made of a liquid-permeable material, which is made of, for example a bobbin fabric can exist.
  • a tube 20 made of a liquid-permeable material which is made of, for example a bobbin fabric can exist.
  • the penetration of concrete components from the outside into the passage 3 is reliably avoided, since when the pressure from the outside increases, the strips 16, 17, 18 and 19 only the openings 9, 10, 11 and 12 arranged in longitudinal rows seal even better. If, on the other hand, the injection liquid from the passage 3 presses outwards against the strips 16, 17, 18 and 19, these are compressed due to their material properties and the joints between the depressions 5, 6, 7 and 8 and the strips 16, 17, 18 and 19 expanded so that the injection liquid can emerge from the injection hose 1 evenly over its length and circumference. The strips 16, 17, 18 and 19 are held in place by the outer enveloping hose 20, so that the openings 9, 10, 11 and 12 are reliably closed again after the passage of the injection liquid.
  • the injection hose 1 according to the invention is relatively insensitive to damage because of its thick walls.
  • the enveloping hose 20 can also accept greater damage without losing its function as a holder for the strips 16, 17, 18 and 19 in the depressions 5, 6, 7 and 8.
  • Elaborate support body u. The like. are not required in the injection hose 1 according to the invention, so that overall there is an economical, easy, reliable and safe to use injection hose 1, which is also reliable in its function, in particular also in the uniform distribution of the injection liquid.
