Definitions

  • Ring beams or ring anchors on buildings, ceilings and window and door lintels are produced in the usual way with - wooden formwork, which is removed after the concrete has hardened and, if necessary, reused.
  • plaster beams in the form of plates in such wooden formwork on the facade side insert the concrete vertically.
  • Such plaster base plates consist, for example, of cement-bound Wood wool.
  • plaster supports of this type which consist of multilayer boards, the layer facing the facade being capable of plastering, while the layer facing the concrete is a thermal barrier coating, such as polystyrene foam.
  • This lost formwork according to the invention for ring beams, ceiling edges and / or lintels with multi-layer panels, which have its outer layer of plaster base and at least one thermal insulation layer, is characterized in that it has metal brackets with at least two sections arranged essentially perpendicular to one another, that the multi-layer panels are spaced apart from them
  • the bearing surface has essentially vertical bores or channels which are dimensioned such that in each case one section of one of the metal brackets is practically completely insertable and that another section of the metal bracket has a fastening device. 5
  • Such lost formwork can be installed quickly, since only the metal bracket with the help of the fastening device on the masonry underneath, roller shutter box or the like at intervals from each other and then the multilayer plates with their holes or channels must be pushed onto the vertical legs of the attached metal bracket.
  • the multi-layer panels which were also required in the previously used wooden formwork, but were only inserted there, thus serve at the same time as formwork, which is kept at the required distance by means of the easy-to-install metal bracket and fastened to the masonry, roller shutter box or the like underneath.
  • the metal brackets required as the only additional means according to the invention save time and labor, wooden formwork and, if necessary, external scaffold structures.
  • the metal brackets In order to avoid measuring the distances between the metal brackets, they can be inserted into the holes in the multilayer panels before fastening, whereupon the formwork assembled in this way is then fastened to the masonry or the like underneath using the fastening devices on the metal brackets. If, on the other hand, you first want to attach the metal brackets and then slide on the multilayer plates, it is advisable to make the holes wider than the width of the metal brackets in order to get a game for inserting the metal brackets.
  • the multilayer boards are, for example, 2 m long in the usual way and for example 24.30 or 36 cm wide.
  • the metal stirrups which are usually made of steel, are fastened to the masonry or the like, for example, at intervals of 30 cm in accordance with the spacing of the holes in the multilayer panels.
  • the multi-layer panels can only consist of an outer layer of plaster base, for example of cement-bound wood wool or the like, and a conventional thermal insulation layer, for example of polystyrene foam.
  • the thermal insulation layer usually has low strength, it is advisable to use the multilayer board to let ten consist of at least three layers, of which the outer layers have mechanical strength and consist, for example, of cement-bonded wood wool, while there is at least one thermal insulation layer inside between these solid plaster base outer layers.
  • the bores spaced apart from one another are expediently provided in the middle thermal insulation layer.
  • the holes or channels are usually subsequently milled into this layer.
  • the fastening devices on the metal brackets can be designed differently. They expediently consist of at least one hole in the relevant leg of the metal bracket and a nail to be passed through this hole or a screw or rivet to be passed through the hole, the size of the holes being dimensioned such that the nails, screws or rivets do not slip through them can.
  • the lost formwork according to the invention is placed on a brick wall, it is easiest to nail the metal brackets to the masonry through said holes, while expediently screwing or riveting on a roller shutter box or the like.
  • the metal brackets can have different lengths, widths and thicknesses.
  • the length of the entire metal bracket and the individual legs results from the usual construction standards.
  • the width and thickness of the metal brackets are chosen so that they give the formwork sufficient stability before concreting.
  • the metal bracket can be 2 to 10 mm thick and 20 to 100, such as 40 mm wide.
  • the shape of the metal bracket may vary slightly depending on the specific application within the scope of the features defined above.
  • the metal bracket can consist of solid material or thin-walled metal sheet stabilized by deformation, which saves material.
  • the metal brackets expediently have a U-shape with a substantially right-angled transition from the U-legs to the U-web which runs without a curvature, the fastening device being located in the U- Jetty is located.
  • the length of the U-web corresponds to the width of the wall minus twice the distance between the outer surface of the multi-layer panels and the holes in the multi-layer panels. If the multi-layer panels are now pushed onto the metal bracket, their outer surfaces are flush with the wall surfaces.
  • the metal bracket suitably has a Z-shape with an essentially right-angled transition from the Z-legs to the Z-web, the Z-web and the two Z-legs being non-curved.
  • the fastening devices can be located in the Z-web and / or one of the Z-legs, since in this case a multilayer plate is only placed on the facade side of the wall and the metal bracket is therefore on the top of the masonry and / or on the Side of the masonry attached as can be nailed.
  • U-shaped metal bracket is used for lost formwork, which is also used for the production of lintels or ring beams and ceiling edges arranged above them.
  • lost formwork which is also used for the production of lintels or ring beams and ceiling edges arranged above them.
  • such combinations are required above doors, windows or roller shutter boxes where the ceiling is to be made from reinforced concrete at a distance from the door opening or window opening or the roller shutter box, but as an integral unit with the lintels located under these openings or roller shutter boxes.
  • Metal brackets for this purpose have two U-legs underneath different lengths, wherein the length of the one U-leg substantially to the height of the lintel or the ring beam and the length of the other U-leg beam substantially to the combined height of the lintel or Rin g and corresponds to the room ceiling above it.
  • an additional stabilizing agent is expediently provided in parallel to the U-web with an additional web which is detachably connected to the free end of the shorter U-leg and to the longer U-leg in its central region.
  • This additional web thus stabilizes the formwork by acting as a spacer between the free end of the shorter U-web and the longer U-web. After concreting, it can remain in the concrete or be removable and reusable. It is delivered as a separate part to make it easier to insert the reinforcement into the formwork.
  • a simple embodiment of this additional web is that it has a preferably hook-shaped pin at one end and a hole at the other end and that the shorter U-leg has a pin that can be inserted into the hole at its free end and the longer U-leg has a hole in its central area, into which the preferably hook-shaped pin of the additional web can be inserted and can be attached by pressing it down.
  • Such additional webs can also be used in the formwork according to FIG. 1a if the U-legs are longer, such as. B. from 24 cm to make additional stabilization appear appropriate.
  • the multilayer boards can have different structures and consist of different materials, but this is part of the prior art.
  • the lost formwork according to the invention shown in Fig. 1a consists of the three-layer multi-layer panels 1 and the U-shaped metal brackets 2, which are attached to the masonry 4 with the aid of a nail 3.
  • the U-shaped metal brackets which are shown in Fig. 1b and 1c, each have an uncurved U-web 5 and two also non-curved U-legs 6. In the middle of the U-web 5 there is a hole 7 through which the Nail 3 is passed through.
  • the structure of a preferred embodiment of the multi-layer panels 1 used in the lost formwork according to the invention is shown.
  • These consist of a plaster base outer layer 8, for example of cement-bound wood wool, from a medium heat Insulation layer 9, for example made of rigid polystyrene foam, and an inner stabilizing layer 10, for example again made of cement-bound wood wool.
  • Bores 11 are provided in the middle layer 9 and have been expediently milled into this layer.
  • the insulation layer 10 and the middle layer 9 have a recess 12 corresponding to the thickness of the metal bracket 5, each opening in the bore 11. In this way it is achieved that the outside of the multilayer board 1 sits flush on the masonry 4.
  • the formwork for room ceiling edge areas shown in FIG. 4a consists of Z-shaped metal brackets 13, the Z-legs 14 and 15 of which are connected to one another by the uncurved Z-web 16.
  • the Z-leg 15 there is a hole 17 as a fastening device, through which a nail 18 is passed and driven into the masonry 19.
  • the multilayer plates 1 are placed on the Z-legs 14.
  • a hole can also be provided in the Z-web 16 through which a nail or a screw or the like is likewise passed for attachment to the masonry 19.
  • FIGS. 5a to 5f is a modification of a lost formwork with U-shaped metal brackets of special design and for a special application. This formwork is used to create a lintel with a ceiling above.
  • the U-web 25 there is a hole 26 through which the rivet 21 is passed.
  • the U-leg 23 has a pin 27 which fits into a hole 28 in the additional web 29.
  • This web 29 has at its other end a hook-like pin 30 which can be inserted into a recess 31 of the longer U-leg 24 and can be locked behind the lower edge of the recess 31.
  • the higher multilayer plates 1 a in the area of the vertical bores 11 have lateral bores 32 which extend through the inner layer and the middle layer through to the vertical bores 11 and enlarge in the outer layer 8 such that the hook-like pin 30 behind the lower edge of the recess 31 can be hung.
  • the additional web 29 stabilizes the formwork, which is used in its lower part to produce the lintel, in its part lying above the additional webs 29 to produce the ceiling.
