Definitions

  • the present invention relates to a board-like element, in particular for concrete formwork, scaffolding and fences according to the preamble of patent claim 1.
  • the same is based on the object of creating an object which is particularly suitable for the building trade and which is immune to damage, corrosion, rotting, deformation, impact, cold and heat under normal use. Other tasks are to protect the element from UV rays, to be able to arrange the manufacture in selectable sizes and shapes without any gaps in a relatively simple and cheap way, and also the automatic self-closing of holes created or created that occur after objects have been removed.
  • FIG. 1 is a perspective view of the element
  • FIG. 2 is a cross section along the line II-II in Fig. 1 on a larger scale of a first exemplary embodiment
  • Fig. 3 is a perspective view, partially without
  • Fig. K is a cross section along the line IV-IV in Fig. 3 in a second embodiment
  • Fig. 5 is a perspective view, partially without
  • FIG. 6 a cross section in a third embodiment with two elements arranged next to one another at a distance for the production of circular or round formwork
  • Fig. 7 is a perspective view of the element with suspension fittings in a fourth embodiment
  • FIG. 8 shows a cross section along the line VII-VII in FIG. 7.
  • the profiles denotes a rectangular stabilization structure made of profiles that run in the longitudinal and transverse directions and intersect and act as a supporting body. To reduce weight, the profiles are hollow and made of steel or another suitable
  • Material such as aluminum, plastic, wood and the like.
  • the stabilizing structure 1 is embedded in a tough elastic covering layer 2.
  • the covering layer 2 consists of car tire granules, fine rubber granules and polyurethane resin.
  • the encapsulation layer 2 has large pores and completely surrounds the stabilization structure 1.
  • the parts 1, 2 are tough-elastic and non-positively connected by the polyurethane resin.
  • the encasing layer 2 closes the stabilizing structure 1, which is in the form of a lattice structure, tightly sealed on all sides.
  • the covering layer 2 is fastened to the support 4 by driven-in nails 3, pins or other third-party bodies. If the nails, pins or other bodies are removed from the covering layer 2, the remaining holes or.
  • the openings are automatically closed due to the viscoplastic nature of the covering layer 2 without leaving any visible traces.
  • the encasing layer 2 is clad with a pore-free, flexible surface protective covering 5, which consists of a rubber-plastic frame.
  • the surface protective covering 5 can also be formed from other suitable flexible plastics, minerals, textiles, glass or metal. _ ix -
  • a flowable mixture of adhesive, car tire and rubber granules is simply passed onto the stabilization structure 1.
  • the passages of the latter are automatically filled tightly.
  • a tough-elastic covering layer 2 is formed, which after a certain time is non-positively connected to the stabilizing structure 1 by adhesive bonding.
  • the profiles of the stabilizing structure 1, which run in the longitudinal and transverse directions, can cross one another and lie welded to one another at the crossing points or be connected in some other way.
  • the profiles running in the longitudinal and transverse directions can have different sizes and shapes from one another.
  • the surface protective covering 5 consists of a mixture of hollow glass beads and polyurethanes, not shown in particular. When the surface protective coating 5 is applied in a flowable state, the said hollow glass spheres float to the surface before hardening and assume almost flush or slightly protruding positions, so that this is roughened.
  • the surface protective covering 5 can be rolled, coated or sprayed onto the covering layer 2.
  • the stabilizing structure and the encapsulation layer 2 are located in a rectangular tubular steel frame 6.7 Leg 8 directed above, which forms an edge protection for the encapsulation layer 2 on all four sides of the element.
  • a mesh-like reinforcement insert 9 made of metal, plastic, glass, carbon fibers or the like is arranged between the covering layer 2 and the surface protective covering 5.
  • One surface of the element is provided with wedge-shaped grooves 10, although there are three longitudinal profiles of the stabilizing structure 1 between each of two grooves lying next to one another.
  • the reinforcement insert 9 replaces transverse struts.
  • the troughs 10 are narrow in the case of a small radius of the curved element (FIG. 6, upper part), but larger in the case of a larger radius (FIG. 6, lower part).
  • suspension elements 14 are attached to the element, which are bow-shaped and are fastened to the stabilizing structure 1 by welding.
