Definitions

  • the invention relates to a connection arrangement according to the preamble of claim 1.
  • connection arrangement of this type is known from DE 39 09 110 A1. With this connection arrangement it happens that due to the strong compressive force exerted by the excavator pushing the shoring plates into the ground, the respectively loaded compression spring unit is too weak and the spring connection is broken. The operator does not notice that the spring is overloaded. This can lead to undesired deformations, tension and malfunctions.
  • the known design offers no further effective possibilities for strengthening the compression spring units and provides for a rigid stop of the side cheeks on the guide profile if the compression spring unit is overloaded.
  • Another disadvantage is that the retaining bolts, which are required to connect the support shoe to the guide profile, are relatively expensive to manufacture and assemble and are often lost in the ground. In addition, they are highly susceptible to corrosion.
  • the invention is therefore based on the object in the known connection arrangement to increase the spring force acting on the support plate without substantial structural enlargement of the support shoe and to enable the support shoe to be pivoted out as far as possible in the elastic range.
  • This version no longer provides for bolt support for the support shoe on the guide profile, but uses a box-shaped pocket to hold the support shoe. In this way, protruding guide profiles and retaining bolts, as well as complicated recesses for inserting the retaining bolts, are avoided in the case of shoring elements in which the guiding profile is already integrated in the shoring element body.
  • the main advantage is, however, that when the support shoe is loaded, two diagonally resilient compression spring units with corresponding lever arms of the support plate are effective, which absorb the support plate movement only elastically and allow a considerable spring force.
  • the side cheeks of the support profile only serve to hold the compression spring units laterally and no longer as a stop. A rigid stop is no longer provided.
  • a shoring element 1 e.g. a shoring plate or a support
  • a U-shaped guide profile 2 is integrated, which is arranged perpendicular to the intended trench bottom.
  • a support shoe 3 is held in the guide profile 2 and is attached to the respective end of a spreader 4.
  • the guide profile 2 does not protrude beyond the inner surface 5 of the shoring element 1.
  • a box-shaped pocket 10 is formed, which serves to receive the support shoe 3.
  • a bearing shell 11 is on Web 8 of the guide profile 2 attached.
  • the support shoe 3 consists essentially of a cross-sectionally H-shaped support profile 12, the web of which forms a support plate 13 and the flanges of which form upper and lower side cheek parts 14 and 15, respectively.
  • the outer dimensions of the support profile 12 are selected so that the lower side cheek parts 15 can engage in the guide profile 2 with play.
  • a cylinder piece 17 (for example a tube) is fastened transversely to its longitudinal direction, which corresponds to the bearing shell 11 and is received therein. This does not require any special surface treatment.
  • a receiving device 19 in the form of a sleeve for the free end of the strut 4 is attached. This is fixed to the receiving device 19 by means of a retaining bolt 20 or the like.
  • a lower compression spring unit 21 is fastened to the underside 14 of the support plate, which is supported on the web 8 of the guide profile 2.
  • each compression spring unit 21 or 22 consists of helical compression springs arranged concentrically one inside the other, preferably wound in opposite directions, each of which the inner compression spring 27 carries an outer compression spring 28.
  • the respective inner compression spring 27 is shorter than the outer compression spring 28 surrounding it, but it is longer than the height of the side cheek part 14 or 15 of the support profile 12 that points away from the support plate 13.
  • the uppermost course of the innermost compression spring 27 is bent at the end resting on the support plate 13 by 90 ° in the longitudinal median plane of this compression spring 27 as a bracket 30 and projects through a (not shown) slot in the support plate 13 and is on this by means of a split pin 31 or The like. Detachably attached.
  • bracket 24 is loosened and the support shoe 3 is inserted into the pocket 10 so that the cylinder piece 17 is received by the bearing shell 11. Then the brackets 24 are inserted and locked against the force of the upper compression spring units 22.
  • the support shoe 3 pivots about the axis of its cylinder piece 17.
  • the support plate 13 is supported on the guide profile 2 by means of the lower compression spring unit 21 and the diagonally arranged upper compression spring unit 22 (via the bracket 24).
  • the double arrangement of compression spring units 21, 22 which are supported at the same time results in a very extensive, exclusively elastic resistance force which counteracts the pressing force of the excavator and which is also noticeable by the excavator operator.
  • the new connection arrangement does not require high quality tolerances and surface treatments. All fasteners can be easily attached and detached, and secured to the installation parts by means of chains or the like so that they are not lost in the ground.
  • the simple mounting of the support plate replaces the complex previous mounting with bearing bolts that can be used in the guide profile and is more robust.
