Definitions

  • the present invention relates to a tank comprising a plurality of prefabricated concrete elements and an elastic profile for such a tank.
  • toggle articulations One problem associated with concrete elements provided with toggle articulations is that, when they are positioned next to one another in a tank, they are exposed to the risk of not sealing tightly, in particular if the tank is intended to hold some form of liquid.
  • One object of the present invention is to propose a liquid-tight tank.
  • a further object of the present invention is to propose an elastic profile for a liquid-tight tank.
  • an elastic profile according to the present invention By utilizing an elastic profile according to the present invention positioned in a vertical joint in a tank, a sealing function of the tank is obtained and, at the same time, a load-transmission function between concrete elements installed side-by-side is obtained with the installation of a single elastic unit.
  • the sealing function is achieved by outer parts of vertical joints in the form of a toggle articulation being sealed by inhomogeneous outer parts of the elastic profile, which inhomogeneous outer parts are positioned with the help of, among other things, a homogeneous central part of the elastic profile.
  • the load-transmission function is achieved by the positioning of the homogeneous elastic central part of the elastic profile between two concrete elements, which, among other things, minimizes tendencies to cracking in the adjacent concrete elements.
  • the utilization of an elastic profile in a tank according to the present invention means that a vertical joint can work in a linear elastic manner in the whole of the pretension force register that is used for tanks of different sizes. This means that calculation analyses for a tank can be performed with currently available software.
  • a tank 1 for the storage of liquid for example, comprises a plurality of prefabricated concrete elements 2 positioned side-by-side above, for example, a concrete slab.
  • the concrete elements 2 are essentially linear blocks with toggle articulations for interacting with adjacent concrete elements 2, that is to say each concrete element 2 has a female part on one side and a male part on the opposite side.
  • Present between each concrete element 2 are vertical joints 5, in which female parts in a concrete element interact with male parts in adjacent concrete elements.
  • An elongated elastic profile 7 is positioned in at least one of the tank's vertical joints 5.
  • An elongated plastic profile 7 is preferably positioned in each vertical joint 5 in the tank 1.
  • the elongated elastic profile 7 has a cross section with a homogeneous central part 8 and two inhomogeneous outer parts 9.
  • the expression homogeneous part is used here to denote a uniform, unvarying part, and the expression inhomogeneous part is used here to denote a part that is not homogeneous.
  • the elongated elastic profile 7 is placed in a female part on a concrete element 2.
  • the elongated elastic profile 7 is preferably made of rubber.
  • the homogeneous central part 8 is positioned centrally in the toggle articulation and thus transmits a load between two adjacent concrete elements in the tank 1, thereby avoiding tendencies to cracking in the concrete elements.
  • the inhomogeneous outer parts 9 are automatically positioned further out in the toggle articulation and thereby seal the vertical joint 5 so that the tank 1 is able to hold a liquid, for example, without leaking.
  • the inhomogeneous outer parts 9 are executed preferably by forming a plurality of projections 10 from a core part of the respective outer part 9.
  • the outer parts 9 will be compressed when two prefabricated concrete elements 2 are assembled adjacent to one another, and the width of the outer parts 9 thus preferably diminishes in a direction outwards from the homogeneous part 8, in order to reduce the total size of the space occupied by the respective outer part 9.
  • the fact that the width of the elongated elastic profile 7 diminishes in an outward direction in the outer parts 9 enables the projections 10 to increase in size as the distance from the homogenous part 8 increases.
  • the elongated elastic profile 7 preferably comprises holes 11 in the homogeneous central part 8 for the purpose of accommodating coring tubes 12 projecting from the prefabricated concrete elements; see Fig. 4 .
  • Coring tubes 12 are cast horizontally into the concrete elements and are so arranged as to receive pretensioning cables.
  • the ability of the elongated profile 7 to be placed in the female part of a toggle articulation, suspended on the coring tubes 12, means that the elongated profile 7 is held in position during assembly of two prefabricated concrete elements side-by-side, so that the inhomogeneous outer parts 9 are positioned correctly in the outer parts of the vertical joint 5 and that the homogeneous central part 8 is positioned correctly at the centre of the toggle articulation.
  • the outer parts 9 are with advantage softer than the homogeneous part 8, that is to say the elongated elastic profile 7 is manufactured with lower elasticity in the homogenous part 8 compared with the two outer parts 9.
  • the fact that the outer parts 9 possess relatively high elasticity enables them to be compressed easily and to seal a vertical joint effectively.
  • the fact that the homogeneous part 8 possesses relatively low elasticity allows it to transfer load effectively between two adjacent, prefabricated concrete elements 2.
