Definitions

  • the invention relates to a shoring device for supporting the walls of a trench with a stepped cross-section, with upper and lower pairs of large-area shoring plates, the lateral edges of which are slidably guided on supports, which are arranged in pairs opposite one another and are kept at a distance by means of cross struts, and which are on both Sides for receiving the edges of the shoring plates have guide slots, the side of which faces the trench wall is formed by a guide flange of the support and the side which faces the interior of the trench is formed by a guide plane.
  • the guide plane can be formed, for example, by a second guide flange or a row of rollers arranged one above the other and rotatably mounted about horizontal axes.
  • the known shoring devices for supporting the walls of a trench with a stepped cross-section have the disadvantage that the supports have two parallel guide slots on both sides need, namely a guide slot for the lower, inner plates and a second guide slot for the upper, outer plates.
  • the production of these supports, each with two mutually parallel guide slots on both sides, is complex.
  • the two guide slots make the supports unnecessarily heavy.
  • the object of the present invention is to provide a shoring device in which the supports are simpler in design and less expensive than in the known shoring devices.
  • the supports have only one guide slot on each side and only one guide plane on which the edges of the upper, outer shoring panels and the inner, lower shoring panels are supported.
  • the guide plane is advantageously formed by two rows of rollers rotatably mounted on the supports about horizontal axes. These rollers for the upper, outer shoring panels and for the lower, inner shoring panels can be mounted on common axes.
  • the shoring device according to the invention has the advantage that it is not only suitable for shoring a trench with a stepped cross section, but also for shoring a trench with a rectangular cross section. In this case, two shoring plates with projecting edges are inserted one above the other in the supports. Such a shoring has the advantage that the working space in the area of the trench bottom is larger than with a stepped shoring.
  • the shoring device shown in FIGS. 1, 2 and 3 is composed of supports 1 arranged opposite one another in pairs, into which large-area shoring panels 2 and 3 are guided so as to be vertically displaceable.
  • the pairs of opposing supports are kept at a distance by means of cross struts 4 and 5.
  • These cross struts 4 and 5 can be stiffeners, but they can also - as shown - be designed as spreaders.
  • Guide slots 6 are arranged on both sides of the supports 1, the sides of which facing the trench wall are formed by a guide flange 7 of the support 1 and the side facing the interior of the trench is formed by a guide plane 8. 1 and 2, the guide plane 8 of a guide slot 6 is formed by a row of rollers 11, 12 rotatably mounted about horizontal axes 10.
  • the distance of the guide plane 8 from the inside of the guide flanges 7 is 50 to 150% greater than the thickness of a shoring plate 2 or 3.
  • the upper and outer shoring plate 2 during step installation has an edge 9 guided between the guide flange 7 and the guide plane 8 who is leading level 8 projects. In this way, space is gained between the upper, outer shoring plate 2 and the guide level 8 in order to be able to insert an inner shoring plate 3 between the outer shoring plate 2 and the guide level 8, the lateral edges of which are also supported on the guide level 8.
  • the inner lining plate 3 is shorter by more than twice the width of a projecting edge of the outer lining plate 2.
  • the edges of the outer shoring plate and the inner shoring plate can run on the same rollers. However, it is advantageous to divide the rollers so that the projecting edges of the outer lining plate 2 roll on the rollers 11, while the edges of the inner lining plate 3 are supported on rollers 12.
  • skids or flanges of the supports 1 can also be provided.
  • strips 19 are arranged, which cooperate with strips 20, which are arranged on the outer side edges of the shoring plate 2 and which have the effect that the upper, outer shoring plates 2 are positively guided in the supports 1, so that cohesion of shoring plates 2 and supports 1 is guaranteed in the longitudinal direction of the trench.
  • the support 1 has two spaced-apart side walls 13 and 14, which on the outside of the trench have an outer wall 15 forming the two guide flanges 7 and at least one row of welded pipes 16 are interconnected.
  • the axles 10 on which the rollers 11 and 12 are rotatably mounted can be inserted through the two side walls 13 and 14 connecting tubes 16.
  • the connecting tubes 16 can also serve as pivot axes for the cross struts or spreaders 4 and 5.
  • the supports 1 are open between the side walls 13 and 14 on the inside. On this open side, the side walls 13 and 14 are provided with reinforcing beads 17 directed outwards. In this way, the support 1 receives a high degree of bending rigidity. On these beads 17 are support plates 18 at g e. welds that support the ends of the axles 10.
  • the distance of the guide plane 8 from the inside of the guide flanges 7 is more than twice the thickness of a shoring wall 2 or 3.
  • the distance of the guide plane 8 from the flanges 7 is less than twice the thickness of a shoring wall, because a guide edge 21 is fastened to the inner plates 3, the thickness of which is only about half as large as the thickness of the inner shoring plate 3.
  • outer shoring panels 2 are reinforced by the attached edges 9 running over the entire panel height, it is expedient to choose the height of these shoring panels 2 to be greater than the height of the inner shoring panels 3.
  • FIG. 4 shows a shoring device according to the invention, in which the shoring panels which are normally to be arranged on the outside and above can also be arranged on the inside by moving them around
  • the individual parts insofar as they have the same effect, have the same reference symbols as in the exemplary embodiment according to FIG. 3, but these reference symbols are provided with a dash.
  • the plate bodies of the shoring panels 2 'and 3' are of completely identical design and the edge regions 32 and 33 are fastened to these shoring panel bodies as prefabricated parts. These prefabricated edge areas 32, 33 can be welded to the same-shaped shoring panel body or can also be screwed on if a detachable connection is desired.
  • the edge region 32 of the shoring plate 2 ' has a support edge 34 which is formed from a relatively thick steel sheet. If the shoring plate 2 'is inserted as the upper outer plate into the guide slot 6 of the support 1', then the projecting edge of the support edge is supported on the guide plane 8, which is formed by a row of rollers 11 '. The other edge of the support edge 34 is guided between the side wall 14 and the bar 19 '. In comparison to the previously described exemplary embodiments, the edge 42 of the strip 19 'is at a greater distance from the guide flange 7'. Between the bar 19 'and the side walls 13' and 14 'of the support 1' guide plates 43 are arranged, on which the edges of the support edge 34 can slide.
  • the outer side 37 of the shoring plate 2 ' is arranged in relation to the guide plane 8 and in relation to the contact surfaces of the supporting edge 34 which rest on it, in such a way that the outer side 37 of the shoring plate 2' is flush with the outer side 36 of the support 1 'when the plate is as outer upper shoring plate is inserted into the guide slot 6.
  • the lower inner plate 3 ' is designed such that the inside 38 of this plate is flush with the inside of the support 1' when the edge region 33 rests on the guide plane 8 or on the row of rollers 11 '.
  • Sheets 39 are welded in between the two side walls 13 'and 14' of the supports 1 for transverse reinforcement.
  • the sheets which form the side walls 13 'and 14' of the support 1 ' are bent in a U-shape to the sides, so that U-shaped roller rails 40 are formed, between the parallel webs of which the rollers 11' are mounted on both sides .
  • horizontal metal sheets 41 are welded into the gaps between the rollers 11 '.
  • vertical stiffening plates 44 can also be provided, which connect the inner sides of the webs of the U-shaped rail 40 to one another. In this way it is prevented that the rails 40 do not bend even when the guide plane 8 is subjected to extremely high loads.
  • stiffening plates 35 are provided at an angle between the inside of the support edge 34 and the inside of the shoring plate 2 '.
