Definitions
- the invention relates to a shoring panel, consisting of profiled sheet metal elements enclosed between two rectangular cover sheets and encircling hollow profiles welded to the cover sheets, for use in trench formwork in civil engineering.
- a shoring panel with a circumferential hollow profile is described in DE 30 15 110 AI.
- This shoring plate which is also provided for supporting trench walls, has essentially outer plates extending over the entire plate surface, a rectangular frame supporting the edges of the outer plate and stiffening, intersecting profiles.
- the frame profiles form, together with the outer sheets, closed box hollow profiles, that is to say a plate frame delimiting the plate body.
- This can consist in particular of an upper anvil cross beam (pressure bar), which is pressed or struck during operation with the excavator bucket; from side end profiles (vertical spar) which, like the anvil profiles, can have a rectangular cross-section; and from a lower pointed or cutting profile with a triangular cross-section.
- one shoring panel is generally placed on the ground, and then spreaders (that is, spacers between facing shoring panels in the trench) are fastened in the panel lying on the ground; the second plate is then lifted over the first plate with a crane and the spreaders are inserted into the second plate from below and fastened there.
- the second plate must be able to be directed exactly by the crane and must be held securely so that accidents cannot occur. It also makes assembly much easier if the plates hang horizontally, as there is no tilting when the spindle is inserted.
- ERSATZBLAH (REGEL26) Side end profiles of the plate are drawn up to approximately the tip of the cutting edge of the lower hollow profile as "free" triangular sheet metal tabs and equipped with a hanging hole.
- the crane can engage the two triangular brackets and further attachment points assigned to the top edge of the plate, that is to say at four points.
- the pierced tabs provided laterally on the longitudinal ends of the cutting edge are generally bent or even broken off after a short period of use. In practice, therefore, the shoring plate is held on the cutting edge during assembly by simply hanging the crane hooks over the cutting edge without a special attachment point. There is then always the danger that one or the other hook will slip laterally when the plate is raised, so that the entire plate will tip over.
- the invention has for its object to provide at the top or bottom edge or cutting edge of the shoring plate a fastening possibility as a stop means for a crane hook, a rope or the like, in particular for hanging the shoring plate in a horizontal position, by means of which neither driving in the shoring plate in the ground still hinders the cutting edge of the shoring plate, which is designed as a hollow profile, is weakened with respect to bending or the like and which cannot be damaged even by driving the shoring plate into the ground or pulling the shoring plate along the trench.
- the new fastening or slinging means like the earlier triangular brackets provided on the longitudinal ends of the cutting edge, is intended to allow a crane hook to be attached directly.
- the solution according to the invention consists in that the pointed hollow profile forming the cutting edge of the lower edge of the plate contains at least one solid steel suspension ring with a cross-section which is at least approximately congruent with the triangular cross-section of the cutting edge and with a partly straight and otherwise approximately semicircular outer circumference, the more rounded
- ERSATZBLAH (REGEL26) Area is welded all around with the pointed hollow profile and its straight area forms part of the lower edge of the plate.
- a solid ring preferably made of cast steel or forged steel, is inserted into the tip or cutting edge of the shoring plate, the outer contour of which, on the one hand, fits exactly into the surface of the cover surfaces surrounding the ring, and on the other hand, part of the cutting edge and its edge Edge itself forms.
- the hanging ring according to the invention is located within the hollow profile frame stiffening the shoring panel, but the ring does not weaken the frame, since its inherent stiffness due to the solid construction is at least as great as the stiffness of the steel sheet to be cut out of the hollow profile for insertion of the ring, and since it becomes part of the hollow profile due to the all-round welding with the remaining hollow profile parts.
- An important advantage of the hanging ring according to the invention is that the ring hole can be so close to the cutting edge that a crane hook - possibly with its hook securing device - can reach over the web remaining between the cutting edge and the hole. As a result, for any assembly work, e.g. with a shoring box, create maximum security.
- An associated advantage of the solution according to the invention is that the suspension ring built into the cutting edge can withstand the forces acting when driving it into the ground due to its inherent stability, at least as well as the other parts of the cutting edge, and that the suspension ring when the sheeting plate is pulled further In the longitudinal direction of the trench, there is no additional load or the pulling forward of the plate is hindered, so that it acts like part of the remaining cutting edge when the shoring plate is in operation.
- ERSATZBLAH REGEL26 Details of the invention are explained on the basis of the schematic representation of an exemplary embodiment. Show it:
- FIG. 1 shows a view of the inside (side facing the trench) of a shoring panel
- Fig. 2 is a section along the line II-II of Fig. 1;
- the shoring plate shown in FIGS. 1 and 2, designated overall by 1, consists of two rectangular cover plates 2 and 3 with profile plate elements 4 enclosed therebetween and a circumferential hollow profile edge welded to the cover plates 2 and 3, all of which are rectangular frame constructs ⁇ on 5 is referred to and consists of a hollow profile 7, 8 or 9 extending continuously from frame corner 6 to frame corner.
- the abutting ends of the hollow profiles 7 to 9 are welded to one another in such a way that the rectangular frame construction 5 acts as one piece.
- the hollow profiles 7 to 9 can be longitudinally welded or seamlessly rolled or drawn. It is therefore preferably not just U or C profiles, but rather tubular hollow profiles.
- the frame structure 5 according to FIG. 1 consists of a pressure beam 7 on the top edge 10 of the plate which is particularly stabilized against bending buckling, a vertical beam 8 on the longitudinal side 11 of the plate which is particularly stabilized against forces in the vertical longitudinal direction, and a cutting edge 12 on the bottom edge 13 of the plate
- the pointed hollow profile of the lower edge 13 has approximately a cross section in shape a right-angled triangle, one catheter 14 of which is perpendicular to the plane of the adjacent cover surface 2, 3, the other of which 15 lies in the surface of the outer cover plate 3 facing the earth during installation, and the hypotenuse 16 of which faces the interior of the trench should.
- receptacle housings 17 with the opening on the inner cover plate 2, when installed, are inserted into the shoring plate 1 adjacent or adjacent to the hollow profiles 8.
- At least one suspension ring 18 with a suspension hole 19 is integrated into the cutting edge 12 adjacent to the lower edge 13 of the hollow hollow profile 9.
- the suspension ring 18 has a rounded circumferential region 20 and a straight circumferential region 21 which is parallel to a tangent to the hole 19.
- the details are shown enlarged in FIGS. 3 and 4. It is important, among other things, that the suspension ring 18 has a cross-section that is identical with the triangular cross-section of the cutting edge 12.
- the suspension ring 18 has a web 24 which extends essentially parallel to the lower edge 13 of the plate.
- This web is preferably designed such that it is strong or voluminous enough at the same time, in order to be equally stable against bending or to be broken like the remaining part of the lower edge 13 of the panel, and slender enough to ensure that a crane hook or similar traction means can be hooked in and secured overlapping directly.
- a hook securing device is envisaged which, as it were, is placed around the web as a continuation of the hook tip when the hook is attached.
- REPLACEMENT BLA ⁇ (RULE 26) If the shoring plate 1 is to be directed approximately horizontally during assembly, the crane can find a stop, for example with a rope or hook, directly in the hole 19 of the suspension ring 18. The hook can grip around the lower web 24 adjoining the lower edge 13 of the plate, since the hole 19 should be correspondingly close to the cutting edge 12. If the plate is to be lifted horizontally with the aid of the two suspension rings 18 according to FIG. 1, the lifting means must also attack the shoring plate 1 at at least one other point.
- suspension eyes 25 with built-in stop means 26 are provided approximately in the upper third of the surface of the shoring plate, but at a distance from the adjacent hollow profiles 7 and 8.
- drawing rings 27 can also be welded to an upper part of the frame 5, in particular to the hollow profile 7, with the aid of eyelets 28.
- the traction means of the crane can also attack, inter alia, appropriately designed attachment points of the receiving housing 17.
- a shoring plate intended for use in trench formwork in civil engineering as part of a shoring box or for slide rail shoring becomes easy to assemble and remains stable on the triangular hollow profile with the cutting edge on the lower edge, if solid steel suspension rings with steel are inserted into the triangular hollow profile Partly straight and partly rounded outer circumference are used, the axial outer contour of which fits into the surface of the cover plate surrounding the ring, the straight circumferential part forms part of the edge of the cutting edge and the rounded circumferential part is welded to the adjacent parts of the hollow profile.
