Definitions

• Formwork panel with edge webs made from a flat extruded profile
• the invention relates to a formwork panel with edge webs that protrude at approximately its right angles to the formwork skin from an 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 directly or indirectly abut and on the rear faces opposite the stop faces connecting means in the form of clamps for mutually fastening the adjoining edge webs, the extruded profiles running in the longitudinal direction of the edge webs or cavities which are enclosed on all sides by walls, and wherein one edge of the web Connecting a formwork skin has an angular space and the parallel, distant edge of the formwork skin in the position of use is encompassed by the clip, the point of attack for the clam mer is a groove or groove running on the back of the edge web, which is arranged approximately in the middle between the edges of the edge web.
• edge webs designed as an extruded profile have a relatively large thickness, so that correspondingly large clamps have to act on them and, due to their hollow cross-section for internal reinforcement, 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.
• formwork panels 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 clamp 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 fastening must therefore be inserted into the narrow side of the formlining or, in the case of the wide extruded profile, be introduced from the side of the formwork 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, while at the same time the attachment of the edge webs to the formwork skin is improved, but relatively small clips can still be used.
• a formwork panel of the type mentioned is characterized in that the edge web is a flat extruded profile and has a full cross-section in the region of the channel or groove, that cavities run inside the edge web on both sides of the channel and that the angular space accommodating the formwork skin on the edge of the edge web near the formlining an elongated cross section, one-piece, on the back of the formlining web, which is the continuation of the boundary wall of the cavity close to the formwork skin and serves as a fastening flange for the formwork skin.
• 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 fastener does not have to be inserted into the narrow side of the formlining, but it can attack provided with a corresponding cross-section transverse to the formlining. This results in an improved fastening of the formwork skin without sacrificing the possible clamping force when connecting edge webs of neighboring control 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 back 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 inventive edge web made of extruded profile 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.
• FIG. 1 is a side view, partly in section, of an edge area of a formwork panel, on the upper edge of which the edge web according to the invention is shown in cross section from an extruded profile,
• FIG. 2 shows a cross section of two adjoining edge webs according to the invention, for the sake of simplicity without formwork skin, which are pressed together by a clamp which engages in a central region of the edge webs provided with a groove, where these have a full cross section and
• FIG. 3 shows a representation corresponding to FIG. 2, an edge web according to the invention being pressed from an extruded profile with an edge web made of flat steel material with a groove-shaped bead through the clamp, again for the sake of simplicity only the edge webs and the complete formwork panels are not shown.
• a shuttering panel designated as a whole with 1 has at its edges, approximately at right angles 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.
• edge webs made of a flat extruded profile made of aluminum, an aluminum alloy or another light metal.
• the formlining can be stiffened by further hollow profiles 4 or the like between these edge webs 3.
• edge webs 3 there are stop surfaces 5 running at right angles to the formlining 2, against which, in the position of use, corresponding stop surfaces 5 of edge webs 3 of neighboring formwork panels - generally 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 which is parallel to it and lies away from the formlining 2 the edge web 3 is encompassed in the position of use 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 formlining 2 must suffice.
• the edge web 3 has a full cross section in the region of this groove * 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.l, but also in Fig.2 and 3.
• the angular space 11 accommodating the formlining 2 on the edge 10 of the edge web 3 near the formlining has a cross-sectionally elongated, one-piece web 15 or flange which rests against the back of the formlining 2 and which continues the boundary wall running parallel to the formwork facing 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.
• Solid material and a cross-sectional reduction 21, of 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 stop or contact surface 5 of the edge web 3 between the two edges 10 and 13 has a flat recess 23, so that in this central area when two edge webs 3 abut one space remains.
• 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. It should be mentioned that the bracket 7, the edge webs 3 only with their

• 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.
• 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 next to one another 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.
