Definitions

  • the invention relates to a formwork panel with edge webs that protrude approximately at right angles to the formwork skin from a flat extruded profile made of aluminum, an aluminum alloy or similar light metal, on which edge webs stop surfaces run at right angles to the formwork skin, on which, in the use position, stop surfaces of edge webs of neighboring formwork panels are indirect or abut directly and on the rear faces opposite the stop surfaces engage connecting means in the form of clips for mutually fastening the adjoining edge webs, the extruded profiles having chambers or the like extending in the longitudinal direction of the edge webs and being enclosed on all sides by walls, and wherein one edge of the edge web for connecting a formwork skin has an angular space and the parallel, distant edge of the formwork skin in the use position is encompassed by the clip, the point of attack for the clip is a groove or groove running on the rear of the edge web, which is arranged approximately in the middle between the edges of the edge web.
  • Such a switch panel is already known from a brochure from MEVA GmbH "ALU STAR", Technical Instructions, May 1992.
  • the edge webs designed as an extruded profile have a relatively large thickness, so that correspondingly large brackets have to act on them and, due to their hollow cross-section for internal stiffening, an additional web running parallel to the formlining must be formed, which is located in the region of the channel or groove.
  • the large cross-section causes a corresponding weight and, above all, correspondingly large brackets with a correspondingly high weight must be used to connect such formwork panels.
  • edge webs are already known from practice in which a light metal is provided for producing the edge webs, the cross section being kept relatively flat. So that these edge webs, which are also known from practice, have the required rigidity, they are also designed as an extruded profile with cavities. This known extruded profile has two points of attack for a clip on its rear side, which are each close to the two edges of this extruded profile, namely on the one hand near the edge located on the formlining and on the other hand near the edge of this edge web remote therefrom.
  • the points of attack overlap the cavities located in the extruded profile, so that with a high clamping force there is a risk that the hollow profile of the edge web consisting of light metal will be pressed in. So that this risk is as low as possible, but without being able to be switched off, the clamp reaches into the area of the edge web, which is located directly on the back of the formwork skin, so that the fastening of the edge web must be on the front edge of the formwork skin. Care must therefore be taken to ensure that fastening means penetrating the edge web in the area of the formwork skin do not make the mutual stop surface located in this area uneven and, above all, leaky.
  • the point of attack of the clamp remote from the formwork skin is conical in cross-section, so that a certain centering effect, but at the same time a force component arises transversely to the boundary wall located there, of one of the cavities of the extruded profile. In this way, deformation cannot be ruled out in this area even with high clamping forces. If such a deformation of the extruded profile in the region of its walls delimiting the cavities is to be excluded, the forces emanating from the clamps must be limited or the walls of the edge web are made correspondingly strong, which in turn leads to a correspondingly higher weight of the formwork panel.
  • the flat cross-section of the extruded profile creates only a very small stop surface on the edge of this edge web near the formlining.
  • the fastening must therefore be introduced into the narrow side of the formlining or, in the case of the wide extruded profile, be introduced from the side of the formlining t facing the concrete. This is either a less stable attachment or an injury to the formwork facing the concrete.
  • the invention is therefore based on the object to provide a formwork panel of the type mentioned, in which the clamping forces can be introduced transversely to the edge web outside the walls of the cavities, in particular also a coupling with edge webs made of flat material made of steel, in particular with a medium one Beading should be possible, at the same time the attachment of the edge webs to the formwork skin is improved, but relatively small brackets can still be used.
  • a formwork panel of the type mentioned at the outset is characterized in that the edge web has a full cross-section in the entire region of the channel or groove, that cavities run on both sides of the channel in the interior of the edge web and that the angular space accommodating the formlining is on the edge near the formlining of the edge web an elongated cross section, has a one-piece web, which rests against the back of the formlining, which is the continuation of the boundary wall of the cavity close to the formlining and serves as a fastening flange for the formlining.
  • edge web is a flat extruded profile, relatively small brackets are sufficient to be able to grasp the edge webs of adjacent formwork panels.
  • Formwork panels can also be connected, the edge webs of which consist of flat material made of steel, as described in DE-A-41 03 775.8. So there is a variety of applications. It is advantageous that the clip engages a groove approximately in the middle of the edge web in order to be able to press the edge webs together.
  • the angular space receiving the formwork at the edge of the edge web close to the formwork has a cross-sectionally elongated, one-piece web resting on the back of the formwork which is the continuation of the boundary wall of the cavity near the formwork and serves as a fastening flange for the formwork .
  • the boundary wall of a cavity of the extruded profile running parallel to the formwork skin parallel to this and to the surface to be concreted does not have to be additional support of the clip and to absorb the clamping forces serve because the point of application for the clip is moved further out from this area.
  • the wall can have the flange-like continuation mentioned, which enables the rear face of the formlining to fit well and to be fastened there.
  • Fastening elements are then located outside the mutual contact areas of edge webs of neighboring switchboards. Also, the fastening element does not have to be inserted into the narrow side of the formlining, but rather can attack with a corresponding cross-section provided transversely to the formlining. This results in an improved fastening of the formlining without sacrificing the possible clamping force when connecting edge webs of neighboring formwork panels.
  • a section made of solid material and a reduction in cross-section can be provided in addition to the cavity arranged there, and the free edge can serve as a stop for a counter-stop on the clamp.
  • the clamp can serve in particular in the case of a force component which also occurs transversely to the formwork skin to align the two connected edge webs which abut the counter stop on the clamp and are thus brought to the same and corresponding position relative to the clamp.
  • the thickness of the edge web can be approximately the same in the region of its parallel cavities on both sides of the channel and the thickness of the cavities and the walls delimiting them can likewise preferably be approximately the same.
  • the result is an edge web of largely constant thickness, which is only interrupted at the rear by the groove or groove, which corresponds to the bead in an edge web according to DE-41 03 775 and can also have its shape and effect. It is expedient if this channel has inclined boundaries, the inclination angle being 45 °, for example, so that they can interact with a correspondingly slanted projection of a clip. This leads to the already mentioned alignment with the counter stop of the clip.
  • the width of the cavities transverse to the plane formed by the formlining can also be approximately the same. This results in cavities of approximately the same thickness and width on both sides of the attack groove for the clamp, which have approximately the same bending strength.
  • the clamp force can thus also be distributed evenly on both sides of the point of application of the clamp.
  • the contact surface of the edge web can have at least one flat recess between the two edges of this edge web, so that a space remains free in this central region when two edge webs lie against one another. Under the action of the clamping force of the clamp, a slight elastic deformation is allowed, which leads to a correspondingly firm compression of the actual contact surfaces and thus to a good seal. Any minor contamination can be absorbed by the recess or the space.
  • a connection with an edge web made of flat material made of steel with a bead according to DE-OS 41 03 775 is made possible in that the groove-shaped groove or the like for the engagement of a clamp is arranged at a distance from the formlining or the free edge of the edge web in which there is a bead for the engagement of the clamp in a flat web made of steel, and that the width of the web made of flat material is in particular equal to the width of the web made of an extruded profile.
  • the abutment surfaces can also serve to align such edge webs made of different materials. It This results in a high load capacity of the formwork panel with a simultaneously favorable or low weight and easy connection to the frame of known formwork panels with flat edge webs made of steel.
  • matching brackets can advantageously be used, i.e. an owner of formwork with formwork panels made of flat webs made of steel can purchase a replacement or additionally a formwork panel with the edge web made of extruded profile designed according to the invention and use it together with the other formwork panels.
  • This also gives the owner of an older formwork the option of gradually converting it to the new formwork panels without being able to use the older formwork panels that still exist.
  • a shuttering panel designated as a whole with 1 has at its edges approximately perpendicular to its shuttering skin 2, generally designated 3 edge webs made of a flat extruded profile made of aluminum, an aluminum alloy or another light metal.
  • the formlining can be stiffened between these edge webs 3 by further hollow profiles 4 or the like.
  • edge webs 3 there are stop surfaces 5 running at right angles to the formlining, against which, in the position of use, corresponding stop surfaces 5 of edge webs 3 of neighboring formwork panels - as a rule directly - rest, as is shown above all in FIG.
  • the extruded profiles forming the edge webs 3 have chambers or cavities 8 running in their longitudinal direction, which are surrounded on all sides by walls 9. This leads to a reduction in weight with high rigidity.
  • One edge 10 of the edge web 3, which is located in the area of the formwork skin 2 has an angular space 11 for connecting this formwork skin 2, one angle leg overlapping the end face of the formwork skin 2, while the other angle leg 12 on the back of the facing away from the concrete surface Formwork skin 2 attacks.
  • edge 13 that is parallel to it and lies away from the formlining 2 the edge web 3 is encompassed in the use position by the clamp 7, as can be seen in FIGS. 2 and 3.
  • the point of attack for the clamp 7 is a groove 14 or groove running on the rear side 6 of the edge web 3, which is arranged approximately in the middle between the edges 10 and 13 of the edge web 3, so that the clamp 7 is not directly up to the formwork skin 2 must suffice.
  • the edge web 3 has a full cross section in the region of this channel 14, so that the forces emanating from the clamp 7 do not lead to a deformation of the cavities 8.
  • These cavities 8 run on both sides of the groove 14 in the interior of the edge web 3 and thus also on both sides of the area with the full cross section. This arrangement is clearly shown in Fig.1, but also in Fig.2 and 3.
  • the angular space 11 accommodating the formlining 2 on the edge 10 of the edge web 3 close to the formlining has a one-piece web 15 or flange which is elongated in cross section and rests against the rear of the formlining 2 and which continues the boundary wall running parallel to the formlining 2 and the surface to be concreted 16 of the cavity 8 near the shell skin.
  • This web 15 can serve as a fastening flange for the formwork skin 2, which is indicated by the dash-dotted line 17 indicating a screw.
  • the entire edge web 3 is further stiffened by this web 15.
  • the clamp 7 can be gripped at a corresponding counter stop 22, that is to say serves as a stop when aligning two interconnected edge webs 3, as can be seen in FIG.
  • the abutment or contact surface 5 of the edge web 3 has a flat recess 23 between the two edges 10 and 13, so that a space remains free in this central region when two edge webs 3 lie against one another.
  • This intermediate space or the recess 23 covers the areas of the cavities 8, so that the actual contact and power transmission takes place laterally of the cavities 8. Correspondingly strong pressure forces can be transmitted and absorbed in this area.
  • the thickness of the edge web 3 in the region of its parallel cavities 8 on both sides of the channel 14 is approximately the same and the thickness of the cavities 8 and the walls delimiting them are also approximately the same, so that largely identical dimensions over the entire width of the edge webs 3 and thus result in the same compressive and bending strengths everywhere.
  • the width of the cavities 8 transverse to the plane formed by the formlining 2 are approximately the same.
  • the boundary 24 of the channel 14 is inclined according to FIGS. 1 and 2 and extends approximately at an angle of 45 ° - in cross section - to the stop surface 5 of the edge web 3.
  • a correspondingly designed projection 25 of the clamp 7 can engage it and a certain one Force component also in the direction of the counter-stop 22 on the bracket 7.
  • the clip 7 only applies its projections 25 within the groove 14 to the edge webs 3 and that a minimal space can also remain in the clamping position according to FIG. 2 between the clamping jaws 26 and the rear of the edge webs 3. But even if clamping forces are applied and transmitted here, too, the cavities 8 located in between cannot be pressed in because on both sides of this cavity 8 located between the clamping jaws 26, a full cross section ensures sufficient support.
  • any clip can engage on the groove 14 or groove, for example according to DE-A-41 03 775 or - as shown in the exemplary embodiment - according to DE-42 36 070. It is provided that the groove-shaped groove 14 for the attack of this bracket 7 is arranged at a distance from the formlining 2 or from the free edge 13 of the edge web 3, in which there is a bead in the case of an edge web 3a formed from flat material made of steel according to FIG 14a for the attack of the clamp 7 is located.
  • the width of the edge web 3a consisting of flat material is equal to the width of the edge web 3 formed from an extruded profile, so that the two different edge webs 3 and 3a according to FIG.
  • Formwork panels with such different edge webs can thus be combined with one another in a simple manner. So it has been possible to create an edge web made of an extruded light metal, which allows a good force application of a clamp 7 at a point at which the cavities 8 are not endangered by this compressive force of the clamp 7, in which also the best possible fastening of the formwork skin 2 is made possible and which can still be combined with an already known and existing edge web so that the same clamp 7 can fix both different edge webs 3 and 3a to one another.
  • Formwork panels according to the exemplary embodiment can thus be combined with formwork panels which have edge webs 3a.
  • the formwork panel 1 has edge webs 3 made of a flat extruded profile made of aluminum, an aluminum alloy or another light metal and thus has a low weight with high rigidity.
  • the points of attack for brackets 7 for mutually setting such edge webs 3 adjacent Formwork panels 1 are located at a distance from the formwork skin 2 at a point where the edge webs 3 have a full cross section and the cavities 8 located on both sides of this point of attack are not at risk of being deformed by the pressure force of the fastening clip 7.
  • a groove 14 or groove is provided as an attack for the clip so that this point of attack is really used.
  • the same clamp 7 can be used, which can also be used for edge webs provided with a central bead made of flat material, so formwork panels with such edge webs made of different materials can also be combined with one another.
