Definitions

  • the invention relates to a trench shoring device with shoring panels and devices for receiving spacers that can be used between two parallel shoring panels and keep them at a distance, each shoring panel being formed by a plate body made of two parallel cover plates and between these web members made of sheet metal arranged in the longitudinal direction of the shoring panel (longitudinal trench direction) are penetrated by reinforcing tubes arranged perpendicular to the longitudinal axes of the web members, and a plate frame which delimits the plate body is formed, which consists of an upper Ambostraverse, a lower end profile and side end profiles.
  • the invention has for its object a trench shoring device to create, which is designed so that it has the required static strength with a small wall thickness and at the same time offers the possibility to keep the required trench profile width small.
  • FIG. 1 and 2 show a shoring plate 1 for a trench shoring device according to the invention.
  • This shoring plate 1 is designed as a so-called "shaft plate”.
  • the shoring plate consists of a plate body 2, the construction of which will be explained separately, and a plate frame 3.
  • the plate frame 3 is formed by an upper frame part designed as an ambostractor 4, which is equipped with eyelets 5 for the crane attack, a lower end profile 6, to which a cutting edge 8 can be attached, and side end profiles 7, which form the vertical end faces of the plate body 2 limit.
  • the lateral end profiles 7 are designed as U-profiles, which are used to hold the support shoes, not shown, of the struts that keep the sheeting plates 1 at a distance. Compared to hitherto custom shoring panels, these lateral end profiles 7 lie in the general shoring panel level, so that the mounting rail formed by them for the support shoes does not protrude in front of the side of the shoring panel 1 facing the interior of the trench. This can have notches 13 at the points where retaining bolts for supporting shoes of the struts are provided in the lateral end profiles (not shown).
  • the side end profile 7 can also consist of three welded U or C profiles.
  • Two U or C profiles 9, 10 are welded to each other with legs facing each other with the legs of a further U or C profile 11 arranged between them, which opens towards the interior of the trench.
  • This U or C profile 11 is dimensioned such that it supports the support shoes (not shown) located at the ends of the struts is able to record.
  • the U or C profiles 9, 10 can be provided with notches 13 at those points where the middle U or C profile 11 has bores for receiving retaining bolts 12 for the support shoes.
  • FIG. 5 to 7 show details of a plate body 2.
  • This consists of a rear cover plate 23 facing the trench wall, with web members 24 which are bent or folded in a trapezoidal cross-section and which are fastened to it at a parallel distance from one another in the horizontal direction, e.g. are welded, as well as a front cover plate 25 (pointing towards the inside of the trench), which is also provided with web members 24 arranged at a parallel distance from one another.
  • the web members 24 of the two plate body halves are arranged offset from one another so that they can be nested and firmly connected to one another.
  • the connection is advantageously made by means of adhesive in order to largely avoid thermal tension and to ensure simpler production.
  • Reinforcement tubes 27 extend perpendicular to the longitudinal axes of the web members 24, which are trapezoidal in cross section, through the plate body 2 and through the side surfaces 26 of the web members 24.
  • FIG. 8 shows a cross section through part of a plate body 2, on the trench-side (outer) cover plate 23 trapezoidally folded or edged web members 24 are welded with a parallel spacing from one another and web members arranged horizontally over the cover plate 23.
  • this part corresponds to the construction of the left half of the plate in Fig. 6.
  • the web members 24 are arranged such that the edges of the cover surfaces 28 of adjacent web members 24 are at a distance which is the same as the width of the part of the cover plate 23 which serves as the base surface 29.
