Definitions

  • the present invention relates to an expansion profile, more specifically for expansion joints in concrete constructions, which expansion profile is of the type comprising two portions to be anchored in the concrete at either side of the expansion joint, and a central compressible expansion portion destined to be located in the expansion joint.
  • Expansion joints in concrete constructions are essential to meet the consequences of thermal expansion of the concrete. If the concrete is reinforced, the reinforcement ends at the place of the expansion joint.
  • expansion joints are traditionally filled with an elastic expansion profile of the above-mentioned kind, at the front and back side thereof an expansion filler plate, for instance of wood fibres, synthetic foam or cork, and at the outer edges of the joint an elastic sealing mass or mastic.
  • an expansion filler plate for instance of wood fibres, synthetic foam or cork
  • the expansion profile mostly of PVC or rubber, in the middle of the joint prevents that water which would possibly leak through the elastic sealing mass would flow straight through the joint.
  • the known expansion profiles comprise a central portion while the two portions at either side thereof are flat wings which show a round thickening at their outer edges.
  • the waterproof capacities are based on a strong compression of the concrete around the thickenings of the wings and the pressure exerted by the thermal deformation of the concrete.
  • the invention relates to an expansion profile which does not show the above-mentioned and other disadvantages, is relatively easy to apply and allows for a good liquid sealing.
  • portions destined to be applied in the concrete are formed by two side walls extending alongside each other which are provided, on their sides directed away from each other, with two elastic ribs between which therefore a space is formed for a material which swells under the influence of liquid, while the expansion portion is formed by at least one elastically deformable bridge between the two side walls.
  • the expansion profile preferably comprises two elastically deformable bridges which thus form, together with the two side walls, a case.
  • Both side walls can extend, at both longitudinal edges of the expansion profile, beyond the bridge or bridges, so that at both edges gutters are formed for applying joint filler plates.
  • the two ribs on a side wall preferably have outsides which extend away from each other from the side wall.
  • the insides of the two ribs on a side wall can be provided with grooves directed towards each other for catching the edges of a strip of swelling material.
  • the invention also relates to such an expansion profile whereby between the rigs on either side a material is applied which swells under the influence of moisture.
  • This material can have the form of a strip.
  • Suitable swelling materials are bentonite, water swelling resin or water swelling rubber compounds or a combination of two or more of these materials.
  • the figure represents a part of a concrete wall 1 in which an expansion joint 2 has been applied.
  • This concrete wall 1 can be part of a building, a reservoir, a canal, a dike, a foundation etc.
  • an expansion profile 3 is present, which is for instance made of PVC and provided with two strips 4 of material which swells under the influence of moisture, and the front side and back side thereof a joint filling plate 5, for instance of wood fibres, synthetic foam or cork, and on the front and back extremities a strip 6 or elastic sealant such as mastic.
  • the expansion profile 3 mainly consists of two side walls 7 and 8, extending alongside and almost parallel to each other, which are connected to each other by two elastically deformable bridges 9 and which are provided, on their sides which are directed away from each other, with two ribs 10 which extend parallel to each other over the entire length of the expansion profile 3.
  • the outsides 11, directed away from each other, of the two neighbouring ribs 10, are slantingly directed to the outside of the side wall 7 or 8 and diverge towards the outside.
  • the elastically deformable bridges 9 are formed by two walls which are bent or form an obtuse angle.
  • the side walls 7 and 8 together with the ribs 10 standing thereon form parts which are cast in the concrete while the bridges 9 form parts which are located in the expansion joint 2 and limit, together with the side walls 7 and 8, a case of which the width of the opening corresponds with the thickness of the expansion joint 2.
  • the application of the expansion profile 3 is done as follows.
  • the edges of the side wall 7 are attached to the inside of the shuttering for the part of the concrete wall 1 at one side of the expansion joint 2, in such a way that the ribs 10 between which a strip 4 of swelling material has been applied, are directed towards the inside of the shuttering.
  • edges of the side wall 7 are located at the surface of the concrete of the first part and the joint filler plates 5 link up with these edges and the concrete.
  • the edges of the side wall 8 are pressed against the joint filler plates 5 and also these edges are located in the surface of the concrete of the second part of the concrete wall 1.
  • this strip 4 pushes the two ribs 10 between which it has been applied away from each other, so that they are firmly pushed against the concrete and especially the slanting outsides 11 are pressed against the concrete so that the possible leak over one of these outsides 11 is closed off.
  • the shape of the expansion profile 3 allows an easy application and allows that the concrete is pressed against it reasonably well.
  • the rigs 10 form as it were valves which are operated by the swelling material and which immediately stop a possible seeping of moisture.
  • the expansion profile 3 is active in both directions and seals both for drinking water as for ground water, salt water, sewage water, and even liquids other than water.
