Definitions

  • the invention relates to a seal for construction joints in and on concrete structures with the features of the preamble of claim 1.
  • a seal of this type is known from DE-GM 84 25 518. It is designed as an injection hose.
  • the hose made of rubber or plastic has a liquid-permeable wall.
  • This wall has a slot extending over its length for the discharge of an injection liquid.
  • a depression Provided in the wall in the area of the slot is a depression, likewise extending over its length, for receiving a strip covering the slot, which is made of a material that changes volume under the pressure of the injection liquid.
  • the wall with the strips is enclosed by a tube made of liquid-permeable material.
  • This injection hose thus consists of three joined parts that form an elongated, flexible structure.
  • the aforementioned strip of compressible material is made of foam rubber.
  • Comparable constructions show and describe the following documents: DE-GM 91 11 114, DE-GM 83 00 766, DE-OS 33 20 875, DE-OS 34 00 654, DE-OS 35 12 470, DE-OS 41 23 067, DE-OS 41 24 628 and EU-PS 199 108.
  • a concrete wall is to be erected on a concrete ceiling
  • a hose of the type mentioned above is placed on the concrete slab and fixed here, specifically within that area of the formwork for the wall to be built is limited. The two ends of the hose are led outside.
  • an injection liquid is injected into the hose, which fills the joints between the plate and the wall in a sealing manner. All of these seals are relatively expensive.
  • sealing materials made of plastic materials (DE-OS 42 26 198 and DE-OS 42 26 385), which swell on contact with water and which are used to seal joints or to compensate for dimensional changes in civil engineering, civil engineering or other technical applications Areas are used. Strips with, for example, a rectangular cross section are made from this material manufactured. When erecting masonry, as described above, such strips are placed and fixed on the concrete slab, within the formwork that serves for the wall to be erected. If such a sealing strip is installed in wet weather, it will swell before the concrete for the wall can be placed in the formwork. If it reaches its maximum volume, its sealing ability is subsequently called into question. This seal is no longer accessible after completion of the wall.
  • the invention is based on this prior art and it aims to propose a seal of the type mentioned which does not have the disadvantages shown, which is therefore of simpler construction and which can also be influenced after it has been installed and incorporated into the masonry, and which can be installed even in rainy weather, without losing its sealing ability as a result; but above all, the seal according to the invention should already have better sealing properties from the outset than the previously known comparable constructions.
  • the invention proposes those measures that are the content and subject of the characterizing part of claim 1.
  • the seal has a base body 1 made of elastic material, which here has the shape of an isosceles triangle in the embodiment shown.
  • the ratio of the width B of the base edge 9 - 9 to the height H of the cross section is approximately 1.5.
  • This base body 1 has an inner, longitudinal, bore-like recess 2.
  • This recess 2 which is circular in cross section here, is so large and lies within the cross section of the base body 1 in such a way that the wall 3 of this recess 2 with the two outer surfaces 4 of the base body 1 each a longitudinal, thin-walled predetermined breaking point 14 limited.
  • this base body 1 has a longitudinal, groove-like depression 5, the side flanks 6 of which protrude toward one another in a wedge-like manner.
  • this groove-like recess 5 lies the insert 7 made of swellable material, which is expediently cast into this groove-like recess 5.
  • the outside 8 of the insert 7, which consists of swellable sealing material, is opposite an imaginary one, the edge edges 9 of the base surface 11 of the base body 1 connecting level 10 slightly set back, so that this outer side 8, when the seal is placed on a flat surface, is somewhat distanced from this.
  • the width B of the base surface 11 of the base body 1 is greater than the width b of the insert 7 and the base surface 11 of the base body 1 starting from the edge edges 9 closes with an imaginary plane 10 connecting these edge edges 1 to form the side edges of the insert 7 subsequent sealing lips 12 an acute angle ⁇ .
  • This acute angle ⁇ is approximately 15 °.
  • a separating slot 13 is also incorporated.
  • the seal according to the exemplary embodiment shown has a triangular cross section, it is within the scope of the invention to also make this cross section rectangular or trapezoidal. Instead of a recess 2, a plurality of such parallel recesses can also be provided within such a cross section.
  • the circumferential contour of this recess 2 is not tied to the circular shape. A polygonal circumferential contour would also be conceivable, in which case this cross section is placed relative to the outer cross section of the seal in such a way that a corner of this cross section of the recess 2 is used to form the predetermined breaking point 14.
  • This seal is installed on a construction site in the manner that was initially discussed in connection with the previously known constructions. The two ends of the seal are led out of the formwork.
  • This seal can also be used in rainy weather because, as the illustration shows, the insert 7 made of swellable material is spaced from the contact surface, here represented by the imaginary plane 10, by the sealing lips 12. If the concrete is filled to erect the wall, its weight rests on the seal and thereby presses the sealing lips 12 flat and thus the insert 7 against the contact surface, the insert 7 now starting to swell when it wets through this contact with the contact surface becomes.
  • an injection liquid is used in this seal, namely in the recess 2, using known devices high pressure (for example 200 bar).
  • high pressure for example 200 bar.
  • the injection liquid under this high pressure not only tears open the predetermined breaking points 14 and enables the injection liquid to step outside into the joints to be sealed, the insert 7 is also pressed with its outer side 8 firmly against the support plane via the separating slot 13. In this way, subsequent sealing defects can be effectively remedied.
  • the seal according to the invention is not only of simpler construction than the constructions mentioned at the beginning, it is considerably more efficient in terms of the function intended for it, despite the simplified construction.
