Definitions

  • the invention is based on a clamping frame for sheeting panels according to the preamble of claim 1.
  • a clamping frame is known from DE-PS 22 57 881.
  • the spreaders are mounted on both sides between the walls of cross-sectionally U-shaped abutment posts pivotable about horizontal pivot axes and are held at right angles to the abutment posts and the shoring panels by means of relatively stiff leaf springs.
  • the arrangement is such that the spreads by relatively small angles, e.g. 5 °, are pivotable about their pivot axis in the abutment post, so that the two shoring plates of a shoring unit can be moved vertically by a certain amount independently of the other shoring plate.
  • the known stenter has the disadvantage that leaf springs change their spring characteristics greatly as a result of contamination, corrosion and oxidation. Furthermore, the assembly is so complex in the known stenter that special tools and experts are required to replace the springs. Finally, the known clamping frame has the disadvantage that the leaf springs are relatively heavy if they are to have a greatly increasing rigidity as the pivoting angle increases.
  • the invention specified in claim 1 has for its object to improve the resilient support of the struts in the abutment post so that dirt, corrosion and oxidation have only a minor influence on the spring characteristics and that despite progressive and high spring stiffness, the weight of the resilient support as well as their material and assembly wall are small.
  • the roller-shaped, rubber-elastic spring bodies clamped between the arched support surfaces and the abutment surfaces roll onto the surfaces moving relative to one another and are thereby forced into the areas of the spring chambers that become narrower in cross section.
  • the progressiveness of the spring stiffness essentially depends only on the angle at which the spring space becomes narrower in the pivoting direction. The larger this angle, the more the spring stiffness grows.
  • the spring body made of natural or synthetic rubber is easily adaptable to the respective requirements, because the load capacity increases with the length of the roller-shaped spring body. With stops it can be achieved that the spring body is protected against destruction or overload.
  • the spring body not only allow pivoting movements of the struts relative to the abutment post about the horizontal pivot axis, but also slight pivoting movements about a vertical axis and also movements in the axial direction of the spreaders.
  • a shoring device is shown with two parallel shoring plates 1, 2, which are kept at a distance via a stiffening frame composed of vertical abutment posts 3, 4 and two spreaders 5, 6 arranged one above the other.
  • the shoring plates 1, 2 are connected to one another via the clamping frame 3, 4, 5, 6.
  • the shoring plates 1, 2 can also be guided vertically displaceably in the abutment post of the stenter, so that the shoring plates 1, 2 and the stenter are only assembled into a shoring device in the trench to be supported.
  • the ends of the spreaders 5, 6 are designed as threaded sleeves 7 in the exemplary embodiment shown here. Threaded spindles 8 are guided in these and are connected to one another via couplings 9. The threads of the two threaded spindles 8 and the two threaded sleeves 7 of a strut 5 or 6 are in opposite directions.
  • the spreaders 5, 6 can be pivoted on both sides via pivot axes 10 in the abutment posts 3, 4, the cross sections of which are U-shaped. So that the shoring plates 1, 2 and the tensioning frame can form a stable unit, roller-shaped, rubber-elastic spring bodies 15 are provided as springs, which strive to keep the spreaders 5, 6 in a horizontal position. So that, for example, the left abutment post 3 can be pulled up or pushed down independently of the right abutment post 4 the spreaders 5.6 can be pivoted about the pivot axes 10 against the action of the spring body 15.
  • roller-shaped spring bodies 15 roll - as shown in particular in FIG. 2 - on a support surface 11 connected to the spreader 5 and an abutment surface 12 connected to the abutment post 3 and are pressed into the narrowing areas of their spring chambers 13 and 14.
  • the pivot axis 10 of the spreaders 5 is mounted in elongated holes 16 which extend horizontally and are incorporated in side walls 20, 21 of a housing which can be inserted and fastened in the abutment posts 3 or 4.
  • the support surface 11 at the ends of the struts 5 or 6 is curved parallel to the pivot axis 10 and symmetrically to the longitudinal axis of the struts 5 or 6 with a radius which corresponds to approximately twice the distance of the pivot axis 10 from the support surface 11.
  • the abutment surface 12 corresponding to this support surface 11 has a vertical plane which merges into a roof surface 18 and a bottom surface 19 approximately in the middle of the spring chambers 13, 14 with a curve 17 which corresponds approximately to the diameter of the roller-shaped spring bodies 15.
  • the roof surface 18 and the floor surface 19 enclose an angle of 90 to 100 ° between them and the vertical plane.
  • the support surface 11 is formed by two commercially available angle profiles, the long legs of which, forming the vertical plane, are welded together.
  • the support surface 11 can also be curved with a radius that corresponds approximately to the distance of the support surface 11 from the pivot axis 10.
  • the roof surface 18 and the floor surface 19 are inclined at such an angle that the cross-sectional constriction of the spring chambers 13, 14 is approximately the same in both pivot directions.
  • the support surface 11 ' is curved around two parallel axes offset symmetrically to the longitudinal axis of the struts 5, 6 and the abutment surface 12' interacting therewith is composed of four partial surfaces, two of which are each in one Angle of 95 ° to each other, and are assigned to a curvature of the support surface 11 '.
  • the four partial surfaces of the abutment surface 12 ' are formed by the inner sides of two commercially available angle profiles welded together with their long legs and are arranged in relation to the two curvatures of the support surface 11' in such a way that the cross-sectional constriction of the spring chambers 13 ', 14' is approximately the same in both pivot directions.
  • the two inner partial surfaces abutting one another like a ridge form a stop 24 against which the two curvatures of the supporting surface 11 ′ abut when the maximum permissible pivoting angle is reached.
  • the two curvatures of the support surface 11 ' are formed by a correspondingly shaped sheet steel wall 26 which is welded to a foot plate 27 welded to the front of the struts 5, 6.
  • the restoring force of the spring body 15 is greater, the larger the radius of the curvature of the support surface 11 or the larger the distance between the two curvature axes of the support surface 11 '.
  • FIG. 6 A particularly advantageous embodiment of the invention results from FIG. 6.
  • a roller-shaped spring body 15 is arranged in each of these spring chambers 13'.
  • the support surfaces 11, 11 ', 11 ", 11 "' are formed by the outer surfaces of a square tube 31, the width of which is approximately one third to half smaller than the width of the square tube forming the abutment surfaces. In the relaxed state, this inner square tube 31 is offset by 45 ° by the roller-shaped spring bodies 15 inserted with prestress held to the outer square tube.
  • the elastic bearing formed in this way is not only elastic about the pivot axis, but is elastic in all directions.
  • a tube with a circular cross section can also be used. Basically, it does not matter whether the abutment surfaces or the support surfaces are attached to the spreader end.
  • the outer square tube 31 can thus be part of the abutment post or the abutment or .. but can also be attached to the front end of a strut. Accordingly, the inner square tube 31 can be attached to the end of a strut or can also be part of the abutment.
