Definitions

  • the invention relates to a concrete formwork panel.
  • frame formwork panels used today are designed as frame formwork panels. They consist essentially of a plate-like formlining, which is often designed as a chipboard with a smooth surface, and a stiffening frame made of metal profiles on the back.
  • the manufacture of the profile frame in particular is complex because the metal profiles have to be cut to length, welded together and color-coated.
  • frame formwork panels have a relatively high weight per unit area of formwork skin, so that the formwork panels, apart from very small formwork panel sizes, have to be moved by crane.
  • the invention has for its object to provide a concreting formwork panel that weighs less formwork per unit area than conventional formwork panels. As a result, larger formwork panels can be moved and set up by hand than before. Transport to the construction site is made easier. There are also opportunities for significantly more rational and cost-effective production.
  • the formwork panel preferably has edge components that are connected to the support structure at least along two opposite edges.
  • the components mentioned including the conventionally non-existent, plate-like back component or back area, are included in the static load-bearing function of the entire panel structure, so that optimized static conditions and material utilization result. This results in weight savings.
  • the struts formed by the intermediate area or spacing component are preferably diagonal struts of alternating direction of inclination.
  • the control panel like conventional control panels, is preferably rectangular or square in plan view. The components mentioned need not necessarily be in one piece, although this is preferred for each of the components.
  • Edge components and / or rear grooves are preferably provided for attaching connecting locks along four edges of the formwork panel.
  • the formwork panel consists predominantly or entirely of plastic.
  • other materials are also possible, in particular wood, metal, etc.
  • a construction is very particularly preferred in which the formwork panel - having no pronounced edge components or without the edge components or including the edge components on two opposite edges - is integrally made of extruded plastic. It is possible to attach two or four edge components, in particular made of metal, to this integral, extruded plastic part, for example by gluing, riveting or the like. Alternatively, it is possible to manufacture the components mentioned at the beginning and then to connect them to one another by gluing, riveting, plastic welding or the like. Another preferred alternative is to manufacture the front component and the rear component from a sheet metal plate and to produce the spacer component from a zigzag-shaped sheet metal plate; these components are then firmly connected to one another, in particular by spot welding or riveting.
  • edge regions of the formwork panel can be formed by parts of the front component, the rear component and / or the spacer component.
  • edge components in particular from thicker sheet metal, and to connect them to the other components.
  • the formwork can be produced by extrusion in spite of the cross section in the manner of a lattice girder, since the cross section does not change along the formwork panel. This also simplifies production in the metal construction of the formwork panel.
  • the static structure of a box girder is obtained in a second section at right angles to the cross section mentioned.
  • the front component, the rear component and the spacer component are formed by a, preferably integral, composite plate. Suitable composite panels can be produced very efficiently.
  • the described edge components can preferably be attached to the composite panel.
  • the rear channels mentioned above are designed in such a way that connecting locks for aligned, aligned clamping of adjacent formwork panels can be attached.
  • the channels have undercuts, the channels are preferably undercut on their sides facing the edge.
  • the undercuts are preferably V-shaped.
  • the channels can also be used to manually grip the formwork panel.
  • Outer, longitudinal grooves are preferably provided on at least two opposite side surfaces. In this way, defined, mutual contact areas are created between two neighboring formwork panels, namely an investment area in the area of the front and another investment area in the area of the back.
  • the support structure has cavities
  • the cavities can preferably be foamed, at least in the area adjacent to the formwork panel front.
  • the material walls of the spacing component can be provided closer together there.
  • the formwork panel has half holes in its edge area, which are open to its rear and to its front side, so that when formwork panels are placed next to one another, complete holes result through the mutual addition of half holes, through which rods can be inserted.
  • These are primarily fixing bars for fixing the spatial position of the formwork panels for concreting and spacer bars for fixing the mutual spacing of opposing formwork panels when concreting walls or the like.
  • the formwork panels can have an overall angular shape, in particular for concreting square columns or concreting walls that converge at an angle or at right angles.
  • Suitable plastics for producing the formwork panel are familiar to the person skilled in the art.
  • PVC and fiber-reinforced plastics are just a few examples among many possible ones. If the material aluminum has been mentioned above, this obviously does not only mean pure aluminum, but also includes suitable aluminum alloys.
  • the invention also relates to a concrete formwork which has a plurality of formwork panels according to the invention which are clamped together by means of connecting locks attached on the rear.
  • the shuttering panel 2 shown in FIG. 1 is made of extruded plastic, the direction of extrusion being perpendicular to the plane of the drawing.
  • the formwork panel 2 consists essentially of a front component 4 in the form of a plane-parallel plate, a back component 6 in the form of a plane-parallel plate, a spacer component 8 in the form of walls placed in a zigzag shape, and two edge components 10 on two opposite formwork panel edges. Because of the shape of the edge components 10, reference is expressly made to FIG. 1 and also to the remaining figures.
  • the back component 6 is less wide than the front component 4, so that a groove 12 is formed on the back of the formwork panel 2 between an edge component 10 and the back component 6, which extends in the longitudinal direction of the formwork panel 2.
  • Each of the two channels 12 is undercut V-shaped on its side facing the edge, because the rear, widened foot of the edge component 10 merges into a narrower cross section there.
  • each of the two edge components 10 has a longitudinal groove 14 on its outside.
  • FIG. 2 the details described can be seen even more clearly because of the enlarged scale.
  • An inclined wall 18 (which can be attributed to the edge component 10 or the spacing component 8) leads obliquely from the V-shaped, bead-like undercut 16 to the next wall of the spacing component 8.
  • the formwork panel 2 can also be formed without a pronounced edge component 10.
  • the two edge components 10 with the two inclined walls 18 can be omitted altogether. Or one can let the wall of the spacer component 8 closest to the edge run at right angles to the front component 4 and the rear component 6.
  • FIG. 3 The illustrated design of the formwork panel 2 is illustrated again by means of a perspective illustration by FIG. 3.
  • a hole 20 can also be seen, which is formed from two half-holes by mutual addition.
  • the hole 20 is open to the front of the panel 2 and to the rear of the panel 2 and extends at right angles to the level of the panel 2.
  • the drawn edge component 10 consists of an aluminum profile.
  • the aluminum profile essentially has a first wall 22, which runs at a certain distance from the edge of the formwork panel 2 from its front component 4 to its back component 6, a second wall that diagonally from the front edge of the formwork panel 2 to the rear of the formwork panel 2 in Distance from the edge thereof, a third wall 26, which extends approximately from the center of the second wall 24 to the rear, widened foot 28, and this rear, widened foot 28.
  • the edge component 10 is preferably connected to the rest of the formwork panel 2 in that its second Wall 24 is glued or riveted to a flat inclined wall of the spacing component 8.
  • edge components 10 of the type shown in FIG. 4 also on the two end faces of the formwork panel 2, namely behind the drawing plane and in front of the drawing plane , attach.
  • edge components 10 of the type shown in FIG. 4 also on the two end faces of the formwork panel 2, namely behind the drawing plane and in front of the drawing plane , attach.
  • front component 4, rear component 6 and spacer component 8 must be cut off obliquely on both end faces.
  • FIG. 5 illustrates how two adjacent formwork panels 2 can be stably aligned with one another by means of a connecting lock or a connecting bracket.
  • the connecting lock 30 essentially consists of an elongated base part 32 with a hollow rectangular cross section, an elongated wedge element 34 accommodated in the base part 32 and displaceable along the base part 32, and two clamp jaws 36 and 38.
  • the one clamp jaw 36 is rigidly attached to the base part 32.
  • the other clamp jaw 38 is pivotable about an axis 40 which extends between the two side walls of the base part 32.
  • a rear lug 42 of the second clamp jaw 38 is in contact with an inclined surface 44 of the wedge element 34. The further the wedge element 34 is displaced to the right in FIG.
  • connection lock 30 described is a separate invention. It can also be used in a technically meaningful manner together with switch panels 2 not according to the invention.
  • connection locks preferably connection locks 30 such as that shown in FIG. 5, can be used on all four edges for all-round clamping of adjacent formwork panels 2.
  • FIG. 6 illustrates how an externally threaded rod 50 can be inserted into a hole 20 mentioned above.
  • the outer channels 14 give enough space for the rod 50 between the rear Feet 28 of the edge components 10 and the front material broadening 52 of the edge components 10.
  • a wing nut 54 is shown, which engages with the thread of the rod 50 and is supported on the back of the two feet 28.
  • FIG. 7 A variant is illustrated in FIG. 7, in which the cavity of the spacing component 8 closest to the edge has additional, longitudinal walls 56.
  • the walls 56 provide additional stiffening there.
  • the formwork panel 2 is easier to nail.
  • Fig. 8 illustrates that formwork panels 2 according to the invention can be produced in different widths.
  • Fig. 8 below illustrates a formwork panel 2 with an angular shape for concreting a rectangular inner corner.
  • a formwork panel 2 with an angular shape can be created for concreting an outside corner.
  • front component walls, the rear component walls and the spacer component walls do not all have to have the same material thickness as shown in the drawing.
  • the front component 4 can be given a greater wall thickness than the rear component 6 and the spacing component 8. It is also possible to vary the wall thickness within the respective component, for example in the middle area of the formwork panel 2 choose larger wall thicknesses than more to the edge.
  • the drawn cavities 58 of the support structure can be foamed with foam plastic.
  • the drawing figures show that the edge components 10 are aligned on the back with the rear component 6.
  • the formwork panels according to the invention can be stacked on top of one another in a good parallel manner, because their rear side is also closed, possibly with the exception of the channels 12. If the cavities 58 are foamed or the described end faces of the formwork panel 2 are also closed, no concrete can run into the cavities 58.
  • edge components 10 are present, these provide an additional stiffening effect. Therefore, it makes most sense if the edge components 10 are provided running at least in the direction in which the formwork panel 2 is longer than in the transverse direction which can be seen in the drawing figures.
  • Usual dimensions of the formwork panel 2 are a width of up to 1 m or even up to 1.5 m and a thickness of 5 to 10 cm.
  • the length of the formwork panel 2 can be chosen practically as desired, with lengths of up to approximately 3 or 4 m generally being considered.
  • a structure can also be selected from a correspondingly thick composite panel or sandwich panel, to which two or four edge components 10 are preferably attached.
