Definitions

  • the invention relates to a base plate for the production of concrete blocks or the like.
  • a wooden core which is clad with a steel plate.
  • concrete blocks or other moldings are usually produced on base plates, which also represents the bottom surface of the corresponding shape.
  • the surface the base plates can also be the surface of the manufactured Represent molded parts.
  • a formwork panel which consists of a wooden core a sheet steel cladding.
  • Such a formwork element is for Production of concrete blocks not suitable because of the dynamic loads cannot withstand the production process.
  • DE 44 03 782 A shows a plate that can be used as a vibrating plate, in which a Wood core is inserted into a steel shell. To the necessary bias to generate it is necessary to wet the wood core and to damp hold. This makes the use of such a plate more difficult, and with one If the plate dries out, it is susceptible to damage. Also tends the wood core to rot prematurely.
  • the object of the present invention is to avoid these disadvantages and to develop a base plate of the above type so that it is inexpensive is producible, has a highly flat and smooth surface and a has a long lifespan.
  • steel plates are provided on both sides of the wooden core are provided, on which retaining pins are welded to the steel plates anchor in the wooden core.
  • the wood core can consist of soft or hard wood, depending on the application essentially provides the supporting structure. It is also possible to use composite materials in which wood with plastic, such as such as pulyurethane.
  • the steel plates resting on the wooden core made from common steels such as ST 37, ST 52 or stainless steel can ensure the hardness and abrasion resistance of the surface and protect the wooden core. It is essential to the present invention that an intimate connection of the steel plates with the wooden core through the holding pins takes place so that no relative movement can take place.
  • Another essential point of the invention is that the steel plates on the Have a continuous and smooth surface on the outside that does not pass through Screws or other fasteners is disturbed.
  • the surface is achieved in that liquids do not penetrate to the wood core can. Due to the planking of the wooden core with steel plates on both sides can cause bending stresses as a result of temperature fluctuations or Differences in humidity can be safely avoided.
  • the holding pins are preferably designed in the form of special nails. This enables easy manufacture, with the steel plates on both sides of the wooden core and put the special nails into the wood core using a press be driven in.
  • the special nails have a specially trained one Head with a tip that favors the welding process with the steel plate. It is essential in this manufacturing process that the contact surfaces of the Are sufficiently hard and resistant to deformation of the press To avoid steel plates.
  • a protection for the edges, which also cohesion of the wood core additionally secures, can be achieved by providing profiles on the edges are that encompass the wood core.
  • the profiles are preferably U-shaped or C-shaped.
  • the steel plates can also the wooden core surrounded like a tub.
  • the steel plates are preferably on at least one edge around the wooden core handled and at least partially cover this. In doing so, a certain one
  • the steel sheet protrudes at a right angle around the longitudinal edges of the wooden core folded over and additionally fixed with special nails. This allows the Long edges not by transport cams or feed pawls of conveyor systems to be damaged.
  • a special security against warping or warping can be achieved if the wood core consists of glued planks.
  • the stability can be increased in particular by the steel plates are biased.
  • the preload is achieved, for example, in that the steel plates are heated before connecting to the wood core so that the thermal change in length during cooling causes the pretension.
  • the retaining pins are arranged in a grid.
  • the holding pins of the two opposite plates are offset are arranged and penetrate more than half the thickness of the wooden plate in this. This ensures that the retaining pins or special nails of the two opposite plates do not come into conflict and the wood core is not weakened unnecessarily.
  • This can be achieved by placing the steel sheets on top one is rotated by 180 °.
  • a particularly compact structure can be achieved in that the steel plates are pressed onto the wooden core. At the same time, this ensures that the base plate is resistant to impressions.
  • a a further extension of the lifespan can be achieved in particular by that sealing elements in the edge area between the wooden core and the steel plate are provided.
  • the base plate consists of a wooden core 1 and an upper steel plate 2 and a lower steel plate 3.
  • On the steel plates 2, 3 are in regular Distances grid-shaped special nails 4 welded, which are intended in penetrate the wood core 1 and establish the connection with it.
  • Fig. 1 are drawn with 5 grid lines, at the intersection of which the special nails 4 the first plate 2 are arranged. Are offset at the intersections the grid lines 6, the special nails 4 of the second plate 3 are arranged. Through the Dislocation is achieved an optimal design in terms of strength.
  • Fig. 4 it can be seen that the wooden core 1 from a plurality of glued planks 7 exists.
  • a U-shaped profile 8 made of steel provided that includes the wooden core 1 and in addition to edge protection represents a stiffening element.
  • Sealing elements 9 in the edge area of the wooden core 1 are pressed between the wooden core 1 and the steel plates 2, 3 in order to To reliably prevent the ingress of moisture or other liquids.
  • the steel plates 2, 3 are turned over at the longitudinal edges at 10, so that improved edge protection is also achieved in this area.
  • the Surface of the steel plates 2, 3 can be protected by an appropriate corrosion protection, such as a hard wax emulsion.
  • the present invention makes it possible to increase the service life of the base plates significantly increase and the quality of the products produced improve by increasing the surface quality and an even Compression is achieved. By eliminating the drawing plate, shorter cycle times can be achieved and shorter vibration times in the production of concrete parts.
  • the cleaning of the base plates according to the invention is also easier Way possible.
