Definitions

  • the invention relates to an injection hose for construction joints on concrete structures according to the preamble of claim 1.
  • an injection hose for construction joints on concrete structures with an essentially cylindrical liquid-permeable wall made of flexible material, such as rubber or plastic, is known, in which the wall has a slot extending over its length for the outlet of the injection liquid has, the wall in the area of the slot has a likewise axially extending recess over its length for receiving a strip covering the slot from material compressible under the pressure of the injection liquid, and in which the wall with the strip is surrounded by a tube of liquid-permeable material is.
  • Such an injection hose has manufacturing disadvantages and because of the relatively narrow outlet slit compared to the width of the recess, relatively high compression pressures are required without a reliably uniform one Distribution of the injection liquid over the circumference of the injection hose can achieve.
  • the object of the invention is to propose an injection hose of the type mentioned which, with simple manufacture and relatively low compressive pressures, permits a uniform distribution of the injection liquid over the circumference of the injection hose, so that construction joints, for example with cement, can be reliably pressed.
  • the passage channel is arranged eccentrically in the cylindrical base body in a further development of the invention.
  • the sheathing consists of a large-mesh, low-stretch fabric that closely surrounds the outer surface of the base body and the outer surface of the strip, because in this way the injection hose does not expand in size when the injection liquid is pressed, but only an internal valve effect due to the compression of the strip material comes into play.
  • the strip which closes the openings in the groove-shaped depression when there is external pressure, for example the concrete pressure, and the better the higher the external pressure is, is compressed from the inside under the compression pressure in such a way that the injection liquid can easily escape. Due to the low-stretch fabric, the injection hose cannot change its cross-section, which could otherwise lead to incomplete sealing of the construction joint.
  • the lateral boundary flanks of the depression and of the strip can advantageously run obliquely towards one another from radially outside to radially inside in a manner known per se. This results in a particularly favorable opening cross-section when the pressing pressure is present from the inside and a particularly reliable seal of the passage when pressure is applied from the outside.
  • the opening cross section can also be favorably influenced with reliable sealing, that the width of the base surface of the recess is only slightly larger than the diameter of the openings.
  • the depression and the strip have an essentially corresponding trapezoidal cross-section, with a slightly curved base surface and an outer surface corresponding to the tube circumference, so that the recess practically completely fills the depression when the strip is at rest.
  • the distance between the radial openings in the recess is of the order of 1 to 3 cm, their diameter between about 3 and 5 mm.
  • a diameter between about 5 and 10 mm is expedient, depending on the molding material.
  • the depth of the depression is approximately in the range between 2 and 5 mm. This then also corresponds to the thickness of the strips in the uncompressed state.
  • Polyvinyl chloride is particularly suitable as the material for the base body, foam rubber, foam rubber or neoprene for the strips.
  • the tube-like covering can be a large-mesh, low-stretch bobbin fabric.
  • the injection hose 1 consists of a base body 2 which has an essentially hollow cylindrical wall and thereby forms a continuous steal central (Fig. 1a, 1d and 3) or eccentric axially parallel cylindrical passage channel 3. Through the passage channel 3, a later hardening injection liquid is pressed in from one end or both ends of the injection hose 1 or possibly also with connections provided therebetween, in order to extend it over the length of a construction joint to be sealed Distribute concrete structure in which the injection hose 1 is inserted.
  • the outer circumferential surface 4 of the base body 2 is equipped with a groove-like, spiral-shaped depression 5 extending over the length of the base body 2.
  • An elongated strip 7 (FIG. 1b) covering the openings 6 is inserted into the recess 5.
  • the strip 7 consists of a material that is compressible under the internal pressure (compression pressure) of the injection liquid, such as neoprene.
  • compression pressure the internal pressure of the injection liquid
  • the sheathing 8 preferably consists of a large-meshed fabric which tightly encloses the outer surface 4 of the base body 2 and the outer surface 9 of the strip 7 and which prevents the strip 7 from escaping even under increased internal pressure (compression pressure).
  • the large mesh size of the tissue ensures an undisturbed discharge of the injection liquid during compression over the entire circumference of the injection hose 1, while conversely a pressure from the outside, for example the concrete, allows the strip 7, as a result of which this is pressed firmly into the depression 5 and for a seal the injection hose 1 is taken care of from the outside, so that no disadvantageous materials get into the passage 3 and can clog it.
  • the solution according to the invention is therefore an internal valve device that is functional at all times created which ensures a uniform distribution of the injection liquid when pressing a construction joint to be sealed without widening the injection hose cross-section.
  • the passage channel 3 is arranged eccentrically in the cylindrical base body 2, the hose cross section can have a relatively small cross section despite a relatively large thickness of the strip 7 and therefore a good opening and closing function.
  • FIG. 3 The embodiment shown in FIG. 3 is an injection hose 1, the recess 5 of which extends over an opening width ⁇ of more than 90 °, so that in this way an even distribution of the injection liquid over the circumference of the injection hose 1 during pressing is achievable.
  • the lateral boundary flanks 10 of the depression 5 and the strip 7 run obliquely towards one another from radially outside to radially inside.
  • the depression 5 and the strip 7 then preferably have an essentially corresponding trapezoidal cross section, with a slightly curved base surface 11 of the strip 7 or the recess 5 and the outer circumference 9 of the strip 7, which is curved corresponding to the tube circumference.
  • All versions also have in common that the width of the base surface 11 of the recess 5 is only slight is larger than the diameter of the radial openings 6, so that the inner valve device of the injection hose 1 according to the invention opens even at relatively low compression pressures, but on the other hand a reliable seal is ensured when the strip 7 is pressurized from the outside.
  • the trapezoidal cross section of the depression it can of course also have any other shape as long as it is suitable for receiving a corresponding compressible strip, a round cord or the like. So it can be semicircular, oval or the like. Shaped.
