Definitions

  • the invention relates to a prefabricated formwork element for the production of blasted concrete corners, with a room-side flat, with reinforcement, as lost formwork serving building board and steel lattice girders as main reinforcement above the building board, which are attached to it, with an angular or round foot and an undercut headboard provided holders is worn.
  • the invention now aims to create a formwork element that can be concreted after being moved to a blasted concrete ceiling, etc. without or with only minor assumptions. If necessary, the desired dimensions should only be determined at the construction site, where changes could also be made at short notice.
  • Another advantage should be that the elements to be transported to the construction site are relatively light in terms of their weight and with simple mechanical aids, e.g. Light cranes can be moved. In the production of self-made ceilings, one often only needs small ceiling elements, the manufacture of which can be carried out manually without a crane.
  • the holders are mushroom-shaped anchors that are non-positively connected to the building board, the reinforcement beams with their longitudinal or tension rods engaging under the heads of the mushroom-shaped anchors or engaging in incisions formed on the anchors, so that a there is a self-supporting formwork element that can be concreted without any supports after moving.
  • Self-supporting reinforcement beams are thus arranged on the building board between the rows of anchors, which engage under the heads of the anchors or engage in incisions formed on the anchors. After the reinforcement beams have been latched in between two parallel rows of anchors and these parts, which are now firmly connected to each other, have been placed on corresponding support bearings of the building to be erected, the concrete is introduced onto the building board as so-called lost formwork.
  • the reinforcement beams can be designed statically in such a way that either no or only minor supports are to be arranged in order to adequately support the reinforced concrete slab during the setting time of the concrete.
  • the formwork parts of the ceiling are assembled in the factory and then stacked and stored on top of each other.
  • bars of additional reinforcement can also be inserted into the incisions of the anchors.
  • This reinforcement can be installed both in the factory and only on the construction site. So you have an easy to move and easy to transport element that consists of lost formwork, the required ceiling reinforcement and the aforementioned mushroom-shaped anchors, and into which - after moving to the construction site - only the required concrete has to be poured to get the finished reinforced concrete floor.
  • the installations can be inserted and the concreting work carried out, as with conventional in-situ concrete ceilings.
  • a prefabricated "lost formwork element" is used for the production of, in particular, inclined, reinforced concrete ceilings provided with self-supporting reinforcement beams, preferably lattice girders, with two base plates forming the finished wall or ceiling surface proposed, the special feature of which is that mushroom-shaped anchors are placed on the base plates in parallel rows at intervals, preferably in cross section, and are non-positively connected to the base plates, and that the longitudinal or tension rods of the reinforcement beams, which also serve as spacers, are the heads of the anchors of both Reach under base plates or engage in incisions formed in the anchors.
  • FIG. 1 shows a base plate, on which anchors designed in the form of mushrooms are attached in parallel rows.
  • Fig. 2 illustrates perspective an apparatus with which the anchor on a Base plate can be placed mechanically.
  • Fig. 3 shows stacked base plates with attached anchors for space-saving storage or for transport to the construction site.
  • Fig. 4 is a perspective view of a ready-to-move element. 5-12 show different embodiments of anchors in a view or in plan view. 13 illustrates another embodiment of the invention.
  • the mushroom-shaped anchors 1 essentially consist of a plate-shaped base 2, the underside of which can be smooth, grooved or structured or also perforated, and possibly have pins 3 around the anchor 1 placed on a formwork panel 4 with the panel during the gluing process in secure in the horizontal direction against displacement. Instead of these two pins (nails), the anchor can also have a hole through which a nail is struck.
  • the anchors 1 are displaced in parallel rows in accordance with the grid indicated on the base plate 4 in Fig. 1, e.g. after applying an adhesive on the underside of the anchor, tap it onto the base plate 4 with a hammer, the pins 3 of the anchor penetrating into the material of the plate and thus allowing precise fixing.
  • the mushroom-shaped design of the anchors they have a tapered intermediate part or incision 5, which widens again at the upper end and forms a mushroom-shaped head 6.
  • these can optionally also be welded or screwed to the base plate 4.
  • Free-spanned reinforcement e.g. in the form of a lattice girder 7, as best shown in FIG. 4.
  • This reinforcement is advantageously introduced by latching the lower longitudinal rods 8 of the lattice girder, which transmit the tensile forces.
  • any suitably designed lattice girder can be used.
  • the distances between the anchors 1 in the longitudinal and transverse directions must be dimensioned in accordance with the load when the concrete is placed on the lost formwork.
  • the base plate 4 represents lost formwork, e.g. Wood panels, composite panels, asbestos cement panels, wood cement panels, plastic u. Metal plates and the like. Since the base plate 4 can also form the finished ceiling view as lost formwork, it is expedient to choose a material for the formwork with a structure with which one can achieve the desired final appearance of the ceiling.
  • anchors 1 serve as spacers both for the self-supporting reinforcement to be latched in and for the additional reinforcement.
  • the anchors 1, e.g. Plastic, metal and wood.
  • the reinforced concrete ceiling according to the invention has the advantage that no subordination is required for the final manufacture at the construction site. It can be seen that elements of any size can only be cut to size on the construction site and can be moved by hand, depending on the lifting equipment available.
  • elements can also be created in the factory by means of a simple device, which elements can have any length corresponding to the usual commercially available panels and a width which allows easy transportation from the factory to the construction site.
  • the anchors 1 used thereon are lowered by means of a holder 10 and on the base plate 4 e.g. glued. You can then raise the bracket 10 for the anchors by one step, as indicated by the double arrow, and place the next base plate on the already finished base plate 4 and provide it with anchors, so that a stack is produced, as shown in FIG. 3 is shown.
  • FIGS. 9 and 10 show an anchor 1 with a round anchor base 2.
  • the anchor according to FIGS. 9 and 10 is provided with an angular base plate 11 and the anchor head consists of a plate 12 undercut on both sides.
  • a variant of FIGS. 9 and 10 is an extruded anchor 1, with the same cross section, wherein the thickness of the plate 12 can be equal to or less than the width of the base plate 11.
  • the anchor head consists of two intersecting and undercut plates 13 (cross anchors).
  • two parallel base plates 14, 14 ' are provided, on which anchors 15 which are mushroom-shaped are provided in parallel rows and at a distance. These anchors are non-positively connected to the base plates 14, 14 ', be it by gluing, nailing or screws 16.
  • the anchors 15 have an annular groove 17 in which the tension rods 18 of, for example, X-shaped lattice girders 19 engage and so on Hold two opposing anchors 15 and thus firmly together with each other on both base plates 14, 14 '.
  • the assembly of the formwork can easily be carried out on the construction site in that the X-shaped lattice girders 19 are stretched somewhat in the area of their tension rods 18 and engage over the conical upper part 20.
  • the spacing of the rows of anchors can be varied and the steel girders themselves can also be dimensioned as desired.
  • the same anchor can therefore be different pick up large steel girders with the appropriate strength.
  • Another option is to insert additional reinforcement.
