Definitions

  • the invention relates to a shoring device for supporting a wall of a construction pit or a trench, consisting of vertical supports that can be inserted at intervals into the ground and insertable between these supports and shoring panels that form a shoring wall with the supports and that on their parallel side edges of both Side walls of the supports located, on the back of the shoring plates are supported guide devices.
  • the known shoring device has the disadvantage that it is very difficult and time-consuming to set up the supports so precisely that, particularly with very deep construction pits and supports of 10 or 20 meters in height, that rela tiv low shoring panels are reliably guided over the entire height of the supports. If the vertical supports are only 1 ° from the plumb line, there is a risk with 10 meter high supports that the upper shoring panels will no longer be reliably grasped by the guide devices and will slide out of the supports.
  • the present invention has for its object to provide a shoring device that is still reliable guidance of the shoring plates achieved even in very deep trenches and not very precisely aligned supports and in construction pits in which earthmoving take place.
  • the guide devices in the plane of the shoring plate are adjustable by means of adjusting drives on the vertical supports. In this way it is possible to adjust the guide devices of the support so that the shoring plates are held securely. Furthermore, it is also possible that in the case of supports that are too close, the guide devices are moved toward the longitudinal central axis of the supports, so that the shoring plates can be inserted without jamming between the supports and their guide devices and can also be pulled out of these guides just as easily.
  • the shoring panels can be held in a staggered arrangement parallel to the longitudinal axes of the supports by a little more than one shoring panel thickness from top to bottom towards the construction pit, each offset from the guide devices of the supports. In the case of very deep construction pits, however, a staggered arrangement of the shoring plates is necessary.
  • the guide elements of the shoring panels are arranged so that each shoring panel can be used independently of another following the excavation and removed from the shoring wall.
  • a wall of an open construction pit 1 is secured by a shoring device, which is composed of, for example, eight, ten or twenty meter long supports 2, which are held in their vertical position by anchors 3, in particular compression anchors, and from shoring plates 4, which are supported on both sides by guide devices 5, 6, which are arranged on both sides of the support 2.
  • shoring devices which are held in their vertical position by anchors 3, in particular compression anchors, and from shoring plates 4, which are supported on both sides by guide devices 5, 6, which are arranged on both sides of the support 2.
  • two, three, four, five or even more shoring panels 4, 4 ' can be arranged one above the other, in particular staggered.
  • the supports 2 are spaced from one another which correspond approximately to the width of the shoring panels 4, 4 '.
  • the supports 2 and the insertable shoring panels 4 held by them form a shoring wall.
  • the vertical supports 2 are in a bore 10th embedded, the end of which is provided with a concrete base 11 which fixes the lower end of a support 2 in a conical opening widening upwards. If the excavation pit 1 is not very wide, instead of the anchors 3 strips 13 or struts can be arranged which are supported against supports 2 of an opposite parallel shoring wall. Such a shoring with spreaders is useful, for example, when laying pipelines and building ducts and wherever the excavation pit does not have to be free of stiffeners.
  • the shoring plates 4 are supported on both sides on guide elements, in particular guide bolts 6, which are laterally projectingly attached to box-like guide bodies 5, which are held laterally adjustable between the flanges 7 and 8 of the supports 2.
  • the shoring plates 4 are inserted between the wall of the building pit 1 to be supported and the guide plane formed by the guide elements 6.
  • the guide elements 6 are arranged on the guide bodies 5 such that the guide planes formed by them are inclined at an angle of 4 ° to 7 ° to the longitudinal axis of the support 2. With this arrangement of the guide elements 6, all shoring panels 4 can be inserted or removed individually and independently of the other shoring panels 4.
  • the guide elements 6 it is also possible to arrange the guide elements 6 such that the guide planes formed by them run parallel to the longitudinal axis of the support 2.
  • the guide elements 6 In order to enable the insertion and removal of the shoring panels 4 independently of the other shoring panels 4, the guide elements 6 must be arranged in such a way that the guide levels are stepped upwards. In this way, two or three sheeting panels 4 can be arranged one above the other, but in planes offset by more than the thickness of one sheeting panel 4 and supported against the supports 2.
  • FIG. 2 shows a view in longitudinal section to the left of the longitudinal axis of the support 2 and to the right of the longitudinal axis of the support 2 a front view of the support 2, i.e. seen from the construction pit 1.
  • Functionally identical parts are provided with the same reference numerals, but the reference numerals of the parts on the right side of the support 2 are additionally provided with a line.
  • the guiding bodies 5, 5 ' can be adjusted within their chambers in the plane of the shoring wall.
  • the guide devices or the box-like guide bodies 5, 5 ' are set and aligned by means of adjustment drives 15 which engage in the upper area and in the lower area of each guide body 5, 5'.
  • the adjustment drives 15 can be formed by hydraulically actuated cylinder-piston units.
  • the adjusting drives 15 are spindle drives with spindles 16, 16 'rigidly fastened to the inner wall 21 and the outer wall 22 of the guide body 5.5' and spindle nuts 17 arranged between the support walls 14, 14 ' tern 17 can be rotated by lever or wrench, which can be inserted and operated through recesses 12 in the inner wall 19 of the support 2.
  • the support 2 is composed of an inner wall 19 forming the flanges 7, 7 ', an outer wall 20 forming the flanges 8, 8' and two at a distance from one another between the inner wall 19 and the outer wall 20 support walls 14, 14 'arranged therebetween, between which the adjusting drives 15 and the spindle nuts 17 are arranged.
  • the height of a guide body 5.5 ' is less than half the height of a shoring plate 4.4' and for supporting a shoring plate 4.4 'there are two on each side of the support 2 identically designed guide bodies 5,5 'assigned to a shoring plate 4,4' are provided, one of which is arranged on the support 2 rotated by 180 ° relative to the other and the guide elements 6, 6 'of which form a common guide plane.
  • This design has the advantage that by turning every second guide body 5.5 'through 180 °, the shoring device for small shoring panels 24 (see FIG. 1) can be converted, the height of which is only half as large as that of shoring panels 4,4'. .
  • the guide elements are guide bolts 6, 6 ', which are held on an inner wall 21 and an outer wall 22 of the box-shaped guide body 5, 5' spaced therefrom.
  • the spindles 16, 16 ' are also fastened to the inner wall 21 and to the outer wall 22 of the box-shaped guide body 5, 5'.
  • the threaded part of the spindles 16, 16 ' extends through bores 18 in the support walls 14, 14' and in the inner wall 21 of the guide body 5 'or 6' located on the other side of the support 2 in its cavity.
  • the adjustment drives 15 are on the left orderly guide body 5 to the adjustment drives 15 'of the guide body 5' arranged on the right side of the support 2 'is offset in height. In this way it is achieved that, despite the large adjustment paths, the adjustment drives 15, 15 'do not require any additional space. Furthermore, the adjustment drives 15 and; the spindles 16, 16 'and the spindle nuts 17 are protected against contamination.
  • additional guide elements 32 for example guide bolts or guide runners, can be arranged on the guide boxes 5, which serve to guide the shoring plates 4, 4 'to be inserted also on their front sides.
  • These guide elements 32 can be made relatively weak and screwed onto the guide body 5 because they do not have to absorb earth pressure and are only intended to prevent the inserted shoring panels from falling out of the supports in the absence of an earth wall to be supported.
  • the guide elements 32 on the front side of the shoring plates 4, 4 ' are important, however, when the guiding plane of the guiding bolts 6 runs parallel to the longitudinal axis of the supports 2, that is to say when the shoring plates are held vertically one above the other or in steps in the guide devices of the supports 2.
  • the vertical edges of the shoring panels and the guide pins 6, or the F üh- guide elements 32 to be designed so that these parts engage around form-fitting manner, so that the guide means 5,6 and 5 ', 6' of the uprights 2 are clamped in the plane of the shoring wall with the shoring panels 4, 4 ', as is the case, for example, with trench shoring devices according to DE-AS 20 21 928.
  • three types of shoring panels are provided for creating a shoring wall, namely square shoring panels 4, rectangular shoring panels 24, which are only half the size of the qua Dratic sheeting 4 and square sheeting 3, the size of which is only half the size of the rectangular sheeting 24.
  • the rectangular sheeting plates 24 can be supported both with their longitudinal edges and with their narrow edges against the guide elements 6, 6 'of the supports 2. Accordingly, the supports 2 can be set to distances which correspond to the length of the longitudinal edges of the shoring panels 24, 24 'or to distances which correspond to the length of the narrow edges of the shoring panels 24, 24'.
  • the width of the shoring panels is twice as large as their height.
  • This sheeting plate 24 can be supported both with its narrow edges 30, 30 'and with its longitudinal edges 31, 31' on the guide bolts G, 6 'of two supports 2.
  • the shoring plate 24 is provided with two cutting edges 27 and 28 which, when inserted into the gap between the earth wall to be supported and the guiding plane formed by the guiding elements 6, 6 ', should lie on the outside towards the earth.
  • the rectangular shoring plate has the first cutting edge 27 on a longitudinal edge of one side 25 and the second cutting edge 28 on a narrow edge of the other side 26.
