Definitions

  • the invention relates to a shoring plate with outer cover plates arranged in parallel and at a distance from one another with one arranged in between
  • Sheeting panels of this type are widely used and have proven themselves well. However, such shoring panels are very difficult to build, are generally complex to manufacture and are very often not sufficiently rigid.
  • the invention is therefore based on the object of proposing a shoring plate of the type described at the outset which is significantly lighter in overall weight and which is nevertheless very rigid and easy to produce.
  • a method for producing such a shoring panel is to be proposed.
  • the stated object is achieved with regard to the design of the shoring panel and starting from a shoring panel of the type described at the outset in that the filling structure is essentially a honeycomb structure formed from sheet metal strips, the honeycomb walls of which are perpendicular to the cover sheets.
  • a honeycomb structure in the specified arrangement makes such a shoring panel very light on the one hand and very resistant on the other. As can be seen, it can be produced very easily using modern manufacturing methods.
  • the honeycomb structure consists of sheet metal strips placed against one another, which are angled along their length in such a way that three walls of a half honeycomb cross section are alternately formed continuously over the length of each sheet metal strip, the sheet metal strips on the adjoining walls via a Connection are connected.
  • the honeycomb structure can thus be produced very easily from a number of identical sheet metal strips, which are each angled transversely so that they form half a honeycomb.
  • the bend creates a kind of angular wave form, so that to form the honeycomb structure, all sheet metal strips have to be angled in the same way and only put in mirror images and must be connected to each other on the adjacent walls.
  • the corresponding bending or deformation of the sheet metal strips can be carried out extremely simply with a single operation on a corresponding sheet metal press.
  • a corresponding design of the sheet metal press it is even possible to press a plurality of such sheet metal strips at the same time, as a result of which the costs in series production can be considerably reduced.
  • the connection of the adjoining walls to form the honeycomb structure is advantageously carried out by spot welding, which can be carried out easily. With simple devices, a whole series of these spot welds can be carried out simultaneously with a single work step. In this manner the inner honeycomb structure can be preformed and kept in stock in the desired dimensions.
  • a supplementary embodiment of the invention provides that an edge area with an inner sheet metal web is separated on both sides of a central area, in which a honeycomb structure is arranged with a cross-sectional area per honeycomb that is significantly smaller than the central area.
  • the screw connection is preferred to the weld here because this avoids welding stresses in the components and because, if one component is damaged, the other component can be removed and replaced simply by loosening the screw connection.
  • Through bolts are preferably used according to the invention for screwing. These are particularly easy to remove from the back, so that replacement is easy.
  • Another embodiment of the invention provides that the walls of the honeycomb structures have at least partial openings. As a result, the weight of the honeycomb structure can be significantly reduced without the strength of the honeycomb structure suffering as a result.
  • Another embodiment of the invention provides that in the foot region of the plate to form a cutting edge, the sheet metal strips forming the half honeycomb structure are left undeformed and with a wedge angle of bevelled edges to be formed are provided, all bevelled edges being covered by a cover plate to form a wedge surface which is welded to bevelled edges. In this way, a stable cutting edge is formed in a simple manner.
  • a shoring plate with outer, parallel and spaced cover plates with a filling structure arranged between them provides that the filling structure consists essentially of spaced and parallel ribs that are perpendicular to the cover plates, the ribs at least in partial lengths are welded to the cover plates.
  • the ribs, so to speak, arranged crosswise result in an extraordinarily high rigidity of the shoring plate in all levels, which is significantly increased due to the welding of these ribs to the cover plates. Ribs and cover plates can thus be kept thin and consequently light.
  • An adaptation to the forces to be supported can be done very simply by using rib heights during production that correspond to the expected loads.
  • the manufacture of the shoring plate according to the invention is also very simple, because all sheet metal parts can be prefabricated very easily before assembly. Any bending or folding work is not necessary. Rather, it is sufficient to simply cut out the individual parts, preferably is done with a laser.
  • the spacing of the ribs from one another is smaller at least in a front and rear edge region of the shoring panel than in the central region.
  • the upper edge area of the plate can be made significantly stiffer. The improvement in stiffness can be determined with the number of head stays used.
  • Another embodiment of the invention in turn provides that the ribs which extend over the entire height of the plate have a chamfered edge in the foot region of the plate to form a cutting edge, with all chamfered edges being covered by a cover plate to form a wedge surface which is chamfered Edges is welded. This makes it very easy to form a closed wedge with a lower cutting edge on the underside of the shoring panel.
  • Another embodiment of the invention provides that the ribs, support plates and head webs at the intersections with other ribs, support plates and head webs have slots reaching up to half the rib height with a slot width only slightly larger than the sheet thickness of the Ribs, webs and support plates.
  • all the ribs, webs and support plates can be formed in one piece and can be inserted into one another in this one-piece form without further connection to form the inner support structure.
  • the handling of many different individual parts, which would also have to be connected to one another in some way, for example by welding, can thus be dispensed with.
  • a further embodiment provides that at least the ribs on at least one longitudinal side facing a cover plate have a plurality of cams distributed over their length, which engage in corresponding openings in the assigned cover plate and are welded there to the cover plate.
  • the height of the cams is dimensioned such that they are flush with the surface of the cover plate in the openings. In this situation, they can in particular be easily welded to the cover plate by means of a laser welding device, so that any subsequent machining work can be omitted.
  • the welding can be carried out in such a way that only the cams are welded to the cover plate.
  • At least individual ribs have openings to save weight.
  • Openings can be formed, for example, in the form of elongated holes or circular holes. They reduce the weight of the ribs and thus the weight of the entire building board. This does not result in a loss of strength.
  • the invention proposes that that the filling structure as a honeycomb structure of a height that corresponds to the thickness of the shoring plate between the cover sheets, prefabricated from sheets, cut to size and then covered by the cover sheets and welded from the outside by laser to the end faces of the walls forming the honeycomb structure.
  • the inner filling structure can be formed in a very simple manner and covered with a first cover plate.
  • this cover plate can then be properly welded from the outside with individual or all end faces of the walls forming the honeycomb structure by means of a laser.
  • the structure thus formed can then be turned over in the desired manner and welded to the next cover plate from the outside in the same way therethrough.

  • the honeycomb structure can be produced in an extremely simple manner in this way.
  • connection of the adjacent honeycomb walls of adjacent honeycombs is produced by spot welding. Such a connection is extremely simple to produce and can be carried out simultaneously at many spot welding points if the device is designed accordingly.
  • a further embodiment provides that at least one opening is made in at least one of the honeycomb walls, which is not placed against other honeycomb walls after the bending as honeycomb walls in the manufacture of the honeycomb structure, in order to save weight.
  • Such an opening can be made particularly easily in the undeformed sheet metal strip, for example by punching.
  • the sheet metal strip made lighter in this way by punching can then be brought into the appropriate shape, for example in a press, to form a plurality of honeycombs arranged one behind the other in the longitudinal direction.
  • a supplementary embodiment provides that a honeycomb structure with a cross-sectional area per honeycomb that is significantly smaller than the central area is prefabricated for a border area on both sides and, like the honeycomb structure of the central area, is covered with it by the cover sheets and on the end faces of the walls forming the honeycomb structure from the outside by means of a laser be welded.

  • the corresponding, self-contained units can simply be placed next to one another and welded to the cover plates in the manner already described. With the different cross-sectional dimensions of the different honeycomb structures, different load areas of such a shoring plate can be dealt with, the areas with the honeycomb structures having a smaller honeycomb cross-section being able to withstand higher loads.
  • a supplementary embodiment provides that between the honeycomb structure with the larger and the honeycomb structure with the smaller cross-sectional area, a separating sheet metal web is provided for each honeycomb, walls of the honeycomb structures adjoining this being connected to the sheet metal web.
