Definitions

  • the invention relates to a shoring device with pairs of mutually opposed large-area shoring panels, which are supported against pairs of oppositely arranged vertical supports, which are kept at a distance from at least one expansion frame, the supports angled from their side walls parallel to the base wall, facing each other and have a wide gap between the legs that are left free and in the columns of mutually opposite supports the expansion frame can be displaced vertically and horizontally positively by means of pressure forces of the expansion frame and transferring on the base wall of the supports and by means of tensile forces of the expansion frame transmitting and on the inside of the two legs of a support running roles is performed.
  • the pressure-transmitting rollers are mounted on axles which are arranged between the upper and lower cross struts of the support frame on the left and right vertical struts of the support frame.
  • the tensile forces of the spreading frame rollers are arranged at the level of the upper and lower cross struts of the support frame on the right and left vertical struts of the support frame.
  • the offset arrangement of the pressure-transmitting rollers and the tensile-force rollers results in a high installation effort and a greater material expenditure. Furthermore, there is also the arrangement of the rollers transmitting the compressive forces between the tensile forces transferring roles unfavorable because the expansion frames are not optimally guided in the supports.
  • the invention has for its object to provide a shoring device that ensures reliable guidance of the expansion frame in the supports of the shoring device with less installation and material.
  • the pressure-transmitting rollers and the tensile-transmitting rollers are arranged on common axes, the pressure-transmitting rollers being arranged in the gap between the legs of a support and in diameter larger than the distance of these legs from the base wall the support and the tensile force-transmitting rollers are smaller in diameter and are arranged on the outwardly directed sides of the compressive force-transmitting rollers.
  • the embodiment of the shoring device according to the invention has the advantage that only two axes are to be arranged on each lateral vertical strut of the expansion frame, on which the pressure-transmitting rollers and the tensile-force rollers are arranged.
  • the upper and lower rollers of the spreader frame can have the greatest possible distance from one another, so that optimal guidance of the spreader frame in the supports is ensured.
  • the shoring device for supporting the essentially vertical walls of an excavated trench is composed of large-area shoring plates 2 and 4 which are arranged opposite one another in pairs and which are supported against vertical supports 1 and 3 arranged opposite one another in pairs.
  • the supports 1 and 3 of the shoring device are kept at a distance from at least one expansion frame 5.
  • the expansion frame 5 is composed of an upper cross strut 6, a lower cross strut 7, a left vertical strut 8 and a right vertical strut 9.
  • rollers 11 are arranged, with which the expansion frame 5 is vertically displaceable in the supports 1 and 3 is performed.
  • stops 13 and 14 can be used, which prevent the expansion frame 5 from accidentally sliding out of one of the two supports 1 and 3.
  • the upper and lower cross struts 6 and 7 of the expansion frame 5 are formed by variable-length spreaders, so that the distance between the vertical struts 8 and 9 can be adjusted from one another.
  • care must be taken that the vertical struts 8 and 9 of the frame 5 are exactly parallel or do not converge more than 1 ° downwards. This approximate parallelism must be observed precisely, otherwise the expansion frame 5 will jam in the supports 1 and 3.
  • a slight convergence of the supports 1 and 3 is not so harmful because the expansion frame 5 can be pressed down with greater forces than can be pulled up. If the supports diverge upwards, pulling the expansion frame 5 out of its guides is still possible.
  • brackets 23 and 24 At the top of the Vertical struts 8 and 9 of the expansion frame 5 are arranged brackets 23 and 24, on which a bar can be placed and with the help of which it is possible, for example by means of an excavator spoon, to press the expansion frame 5 in the supports 1 and 3 downwards.
  • the supports 1 and 3 have a C-shaped profile. With the base wall 12, the support 1 rests on the inner wall of the shoring panel 2. A support 1 or 3 is attached or welded to each of the two lateral edges of the shoring plate 2.
  • axles 10 are fastened, on which the rollers 11 and 11 'running on the base wall 12 of the supports 1 and 3 are mounted.
  • the rollers 17 and 17 ' are also mounted on the axles 10, which transmit the tensile forces acting in the expansion frame 5 to the flanges 16 and 16' of the supports 1 and 3.
  • the rollers 11 and 11 'which transmit pressure forces are larger in diameter than the distance between the base wall 12 and the legs 16 and 16'. Therefore, these pressure-transmitting rollers 11 and 11 'are arranged in the gap between the opposing legs 16 and 16' of the supports 1 and 3.
  • the rollers 17 and 17 'which transmit tensile forces are smaller in diameter and are arranged on the respectively outwardly directed sides of the rollers 11 and 11' which transmit pressure forces.
  • the diameters of the rollers 11 and 17 or 11 'and 17' are selected so that that when the pressure-transmitting rollers 11, 11 'rest on the base wall 12, the tensile-force rollers 17 and 17' are at a small distance from the inside of the legs 16 and 16 'of the supports 1 and 3.
  • a pressure-transmitting roller 11 or 11 'and a tension-transmitting roller 17 or 17' are integrally connected to one another.
  • both sides of the expansion frame 5 there are two vertical walls 19 and 19 ', at a distance from one another, into which the axes 10 are inserted and welded and on the projecting ends of which the rollers 11, 17 and 11', 17 'are rotatably mounted.
  • Thrust rings 18 and 18 ' are welded to both ends of the axle 10 and hold the rollers 11, 17 and 11', 17 'on the axle 10.
  • the base wall 12 or the support 1 or 3 is about three times as wide as a side wall 15 or 15 'of a support 1 or 3.
  • These supports are to be arranged on the edges of the shoring plate, so that the shoring unit forms a so-called edge-supported shoring unit .
