Definitions

  • the invention relates to a formwork element and its manufacturing process, in particular an element of formwork for the underside of a spiral staircase, to pour in concrete.
  • the underside of a spiral staircase constitutes a helicoid.
  • its generator is a straight line
  • the helicoid constitutes a curved surface, possible by means of a flat surface only pleating, deforming or tearing it.
  • DE-A1-44 20 849 further discloses a method of construction consisting in placing between the walls verticals delimiting the staircase, spacers taking support on supports, and defining the shape of the surface to be poured. These spacers then serve as support for continuous elements, concrete molding.
  • the process of the invention essentially consists in make the formwork element from an element rigid, self-supporting, serving both as a formwork and support element, both for the reinforcement only for pouring concrete.
  • the method consists in cut a block, generally parallelepiped, of synthetic foam, to give one of its faces (the upper side in use position) the shape of a portion, usually a quarter, of the surface lower, helical, of the staircase to be made.
  • a rigid skin is then poured in synthetic resin, which will serve as a support surface for reinforcement, and molding and support for the fresh concrete.
  • the rigid panel will be glued to the base surface, so as to provide a block a part, the two opposite faces of which are protected, one by the panel and the other by the resin skin.
  • the volume of synthetic foam essentially serves as a retractor, between the upper skin molding, synthetic resin, and panel lower support.
  • This foam element presents as advantage of being easily cut to the desired shape using a wire, abrasive or heating, in known manner in the technique, to be light, and to present a good compressive strength, allowing maintain the molding skin in a predefined position relative to the underside.
  • Figure 1 shows a formwork element according the invention
  • Figure 2 is a block diagram of the cutting of a formwork element according to the invention.
  • an element formwork 1 consisting of a block 2 of synthetic foam - usually polystyrene or analogous - whose upper face 3 is cut to the shaped like a helicoid, and is covered with a skin 4.
  • the skin 4 is intended to serve as a waterproof surface, concrete molding. Before pouring concrete, it will also serve as a work surface for workers, for example scrap metal workers, and support workers for the reinforcement carried out. To this extent, it must therefore be essentially rigid and undeformable, for distribute substantially over the entire surface of the synthetic foam localized loads, for example the workers' weights, and resist punching, to prevent it from being punctured by falling tools, and analogues, or by the reinforcement.
  • the skin 4 is made of resin reinforced synthetic, which ensures the qualities tightness, rigidity and resistance to punching.
  • such a formwork element is performed as follows.
  • Parameters of the helical surface to be molded are imposed by the characteristics of the staircase to achieve.
  • the generator of the helical surface being a line, these parameters are used to control a wire cutting machine (heating wire or abrasive wire) which cut a block of polystyrene to give one of the its faces the desired shape of a section of the helicoid.
  • FIG. 2 The schematic diagram of such a division is illustrated in Figure 2, in which we see a block raw 2 to be cut, resting on a movable plate 5 in translation along arrow H, and in rotation according to arrow R.
  • a cutting wire 6 is also mounted movable in the vertical direction on supports 7, 7 ', the speeds of displacement V, V 'of the two ends of the wire are independently controlled, as well as the speed of rotation R and the speed of translation H of the plate.
  • the combined movements of translation and rotation of the plate 5 bring the wire 6 to penetrate the block, and cut it along a surface whose parameters are provided by the velocities V, V ', R and H.
  • this coating can for example be a paint to polyurethane.
  • a skin is formed rigid, made of synthetic resin, preferably reinforced with a fiber mat. So conventional, the resin is applied in the fluid state, after adding a hardener. According to a mode of preferred embodiment, a first coating of resin, on which the mat is deposited, on which we superimpose then a second layer of resin, so as to drown the mat in the resin.
  • a roller spike
  • the resin will for example be a polyester resin.
  • the mat is a mat of fibers inert under the conditions of use, for example glass fibers.
  • a formwork element 1 comprising a tight and rigid molding skin 4, of the desired shape, supported by a support element 2 in a position such that when the support element 2 is laid flat on a horizontal support, the skin 2 is found in the desired orientation for molding.
