Definitions

• the invention relates to a formwork panel with at its edges at right angles to the formwork edge webs made of flat material, the cross section of which extends from the scarf skin to a free edge, this cross-sectional profile being directed away from the scarf skin at least and the free edge of the free edge
• the greatest width of the edge web is limited, the edge webs of neighboring formwork panels directly or indirectly abutting the edge webs in the position of use and attack connecting means for mutually fastening the adjoining edge webs, the area between the two aligned longitudinal edges serving as an attachment for the edge web of the neighboring formwork panel of the edge web jumps back towards these centers in the direction of the center of the formwork panel.
• Such a formwork panel in which the edge webs of aligned and adjoining formwork panels lie directly against one another, is known from DE-PS 21 37 505.
• Bolts which pass through keyhole-like perforations of the edge webs and which have a stop projection and a counter-stop arranged at a distance therefrom serve as connecting means for mutually fastening the edge webs lying against one another.
• edge webs are flat in these previously known solutions in order to allow a tight abutment or insertion of intermediate parts.
• the invention is therefore based on the object to provide a formwork panel of the type mentioned, in which the edge webs can be made of flat material, but nevertheless a high rigidity can be achieved with good sealing of adjacent edge webs.
• the solution is based on the knowledge that it is sufficient to seal the adjoining edge webs - as is already known from hollow profiles - if two edge areas are available as sealing surfaces and contact surfaces, so that the edge web consisting of flat material due to the described deformations of its cross web can obtain a significantly higher rigidity compared to a consistently flat edge web.
• this results in the additional advantage that clamps or clamps can act on the beads with their clamping jaws in the manner known for the hollow profiles forming the edge webs.
• clamps or clamps can be attached to these, which have a stiffened cross-sectional profile, but nevertheless consist of flat material, which have the advantage of being able to be attached to practically any point in the course of the edge webs and which also have a very high clamping force and therefore good sealing enable the adjoining edge webs or the interposed Ausgeteichsteite or the like. Nevertheless, the overall weight of the formwork panel can be kept lower because the much heavier edge profiles are replaced by edge webs made of flat material that are stiffer than simple web-shaped edge webs.
• the bead designed for the engagement of a connecting clip or clip has a distance from its outside located on the outer circumference of the formwork panel to a plane touching the two corresponding outside sides of the longitudinal edges of the web. It is sufficient, but at the same time also advantageous, if the distance of the outside of the bead from the plane of the longitudinal edges of the web corresponds approximately to or is greater than the elastic deformability of the web when jammed with a neighboring web.
• the cross-sectional thickness of the edge webs can be, for example, approximately 1/2 cm to approximately 3/4 cm and in particular approximately 6 mm. With a cross-sectional thickness of about 6 mm, a distance of the outside from the plane of the longitudinal edges in the order of about 1/2 to 1 mm is sufficient to achieve the desired firm pressure of the aligned longitudinal edges and sealing surfaces of the edge webs, on the one hand, and the elastic, on the other Consider deformation under the influence of the clamping force.
• the surfaces of the two longitudinal wheels of the edge web located on the outside are expediently flat and in alignment with one another and the width of at least the longitudinal edge closer to the formlining can at least correspond approximately to the thickness of this formlining, but expediently both longitudinal edges can be of equal width, so that overall a symmetrical Cross section results and the bead can also be arranged in the middle of the edge webs.
• edge webs that recesses towards the center of the formwork board in relation to the longitudinal edges can be flat except for the bead. This makes this area available to allow additional stiffening webs, for example, to be blunt and to be welded to the edge webs.
• a sleeve for a clamping point could be fixed in this way on the inside or inside surface of the edge webs. In this way, supports or brackets can also be easily attached to the edge bars.
• the bead arranged in the longitudinal direction of the edge web - in particular in its center - can run continuously over the entire length of the edge web and in particular with a constant cross section.
• a clamping device can be attached to practically any point on the edge web.
• the edge webs can be produced in a continuous deformation process from an originally flat flat material.
• perforations penetrating the edge webs can be provided, for example, for attaching connecting bolts or the like.
• connecting bolts either adjacent formwork panels could in turn be attached to one another or additional parts such as work platforms, supports and the like could be coupled to adjacent edge webs of adjacent formwork panels.
• the arrangement of these coupling perforations in the area of the beads has the advantage that the clamping forces applied in the longitudinal direction of the bolts are also introduced on the beads provided for this purpose.
• the perforations provided in the area of the beads could have a circular cross section and their diameter in particular correspond approximately to the greatest width of the bead, so that the perforation walls also penetrate the lateral boundaries of the bead.
• the head of a connecting screw and also a nut cooperating with a threaded bolt could each rest on the surface of the area of the edge webs that recesses laterally to the bead, facing the middle of the formwork.
• transitions from the longitudinal edges to the central region of the edge web and / or the lateral boundaries of the bead can run obliquely, for example at an angle of approximately 45 degrees, with respect to the cross-sectional profile of the edge web. This not only results in good stiffening, but also permits the desired deformation of the cross section of the edge web without the risk of damage or weakening by the deformation process.
• a formwork panel is of relatively low weight, because its edge webs can be made of flat material, but high forces can still be transmitted and clamps or clamping devices can be used to connect neighboring formwork panels, i.e. the advantages of the formwork panels with flat edge webs will be associated with the advantages that formwork panels have with edge webs formed from hollow profiles, without having to accept a significant increase in weight.
• a formwork panel 1 has at its edges, at right angles to its formwork skin 2, peripheral edge webs 3 made of flat material, on which, in the position of use, corresponding edge webs 3 of neighboring formwork panels 1 directly or - according to FIG. 2 - directly and with the aid of connecting means, in the exemplary embodiment a clamping device 4 are connected.
• FIG. 2 illustrates that the area 5 between the two longitudinal edges 6 and 7 of the edge web 3, which are in alignment with one another and serve as an attachment for the edge web 3 of the neighboring formwork panel 1, in the direction of these longitudinal edges 6 and 7 springs back towards the center of the formwork panel 1 and that in this recessed area 5 an oppositely shaped channel or bead 8 is arranged which is open towards the center of the formwork panel.
• Fig. 2 illustrates that a bead 8 of an edge web 3 interacts with the bead 8 of the edge web 3 of the neighboring formwork panel 1 when the connecting terminal 4 engages these beads 8 to connect the formwork panels 1.
• the mutually facing outer sides 8a of the beads 8 are brought closer to one another or even pressed together by the clamping force, but in the starting position, that is to say without deformation by the clamping force, they are at a distance from one of the two outer sides of the longitudinal edges 6 and. 7 of the webs 3 touching level. This ensures that the longitudinal edges 6 u. 7 of the webs 3 come into contact with one another and lie close to one another and not a premature contact of the outer sides 8a of the beads 8 such a tight connection of the longitudinal edges 6 u. 7 prevented.
• a corresponding contact pressure can be generated and transmitted in the area of the longitudinal edges 6 and 7 via the spring force of the edge webs 3.
• the distance A of the outside 8a of the bead 8 from the plane E of the longitudinal edges 6 u. 7 of the web 3 corresponds approximately to the elastic deformability of the edge web 3 when jamming with a neighboring web or is even larger, so that, contrary to the illustration in FIG. 2, the outer sides 8a of adjoining edge webs 3 do not come into contact with one another.
• Fig. 2 illustrates that the surfaces of the two longitudinal edges 6 and 7 of the edge web 3 located on the outside are flat, namely lie in the plane E, and are flush with one another.
• the width of at least the longitudinal edge 6 closer to the scarf skin 2 corresponds approximately to the thickness of this skin 2, so that the recessed area 5 can begin directly on the rear side of the skin 2, but the shell skin can reach the inside of the longitudinal edge 6 except for a sealing joint can.
• both longitudinal edges 6 u.
• edge web 3 stiffened by the recessed area 5 on the one hand and the bead 8 on the other hand arises if, as provided in the exemplary embodiment, the one arranged in the longitudinal direction of the edge web 3 and over the entire length of the edge web 3 continuous and with a constant cross-section continuous bead 8 is arranged in the middle of the cross section of the edge web 3.
• the area 5 of the edge webs 3, which springs back towards the center of the formwork panel 1 and the longitudinal edges 6 and 7, is flat except for the bead 8, so that stiffening profiles 9 arranged transversely to the edge webs 3 provide good support when they impinge on these areas 5 and find a correspondingly wide area for making a weld.
• a clip 4 can thus be pushed over edge webs 3 lying together without requiring an excessively large opening path on their clamping jaws 10 and clamping pieces 11.
• the edge webs 3 can be penetrated in particular in the area of their bead 8 by perforations 12, on which fastening bolts can be arranged instead of the clamp 4 or in addition thereto. While the clamp 4 allows attachment to a practically any area of the edge webs 3, fastening bolts could be provided at pre-selected locations with the aid of perforations.
• additional parts such as brackets or support brackets can be fixed with such fastening bolts.
• the holes 12 provided in the area of the sikken 8 have a circular cross section and their diameter corresponds approximately to the greatest width of the beads 8, so that the perforation walls also penetrate the lateral boundaries 8b of the beads 8.
• the flat zones of the recessed areas 5 adjacent to the perforations 12 are available as supports for a head or a nut or a projection of a fastening bolt.
• transitions from the longitudinal edges 6 and 7 to the central region 5 of the edge web 3 and the lateral boundaries 8b of the bead 8 are oblique with respect to the cross-sectional profile of the edge web 3, in the exemplary embodiment at an angle of approximately 45 degrees. This has the effect that the transitions originating from adjacent longitudinal edges 6 enclose each other approximately at a right angle, which on the one hand means a good compromise in terms of forming technology and on the other hand in introducing the clamping forces.
• a formwork panel 1 of high rigidity in which the edge webs 3, despite being made from flat material, have high rigidity with a relatively low weight due to the shape of their cross section.
• a clamp or clamp 4 of a relatively small span is sufficient to be able to connect the edge webs, but the stiffening bead 8 advantageously allows the attack of such a clamp 4, so that the perforations 5 which are possible per se could even be avoided .
• the brackets 4 can also be used to make the mutual connection at virtually any point on the contacting edge webs 3. So it will take advantage of the relatively light weight of the Flat material existing
• Edge webs 3 are connected with the possibility of being able to attach clamps at any contact points, that is to say to be independent of predefined perforation distances.
• the sikken 8 thus on the one hand have the function of increasing the rigidity of the edge webs 3 and on the other hand they form a favorable point of attack for the terminal 4.
• the formwork panel 1 has edge webs 3 made of flat material that protrude at right angles to the formwork skin 2 at its edges, which, in order to increase the rigidity between their two mutually aligned, serve as an attachment for the edge web 3 of a neighboring formwork panel 1, longitudinal edges 6, 7 have an area 5 which springs back to the center of the formwork panel 1, within which a channel or bead 8 which is in turn formed in the opposite direction and is open to the center of the formwork panel is arranged.
• the result is an edge web 3 of high stiffness consisting of flat material, on the bead 8 of which conventional clamps or clamps 4 can also engage without requiring the high weight of hollow edge profiles.
• the cross-sectional thickness of the edge webs 3 can be, for example, about 1/2 cm or 0.6 cm, and the distance between the outside 8a of the bead 8 and the plane E can be between 1/2 and 1 mm, possibly a little more.
