Definitions

  • the invention relates to a frame for formwork panel according to the preamble of claim 1.
  • a frame is known from DE-A 34 29 304.
  • the depression for attacking a crowbar is arranged in that corner region of the hollow profile which is formed by the outer side surfaces and the surface facing away from the formlining, that is to say an end web remote from the formwork facing and the edge web. If such a formwork panel with a frame leg is set up on a standing surface, it can be lifted and offset or aligned somewhat using a crowbar attached to the recess.
  • Hollow sections are mainly used as frames for formwork panels when they are heavy. If a crowbar is now attached to the recess mentioned in an outer corner of the hollow profile, the resulting forces are also introduced to a considerable extent into the edge web serving as a stop and seal with a neighboring formwork panel, which can lead to its deformation, so that bumps and the like can form and the tightness when assembling such formwork panels at least after repeated alignment and Moving with the help of a crowbar is even less guaranteed.
  • the reaction forces of the crowbar can be kept away from the edge web, because the depression is no longer made in the corner area, but only in the end web, so that the edge web remains undisturbed by the depression.
  • the corner areas of the hollow profile are preserved according to the invention and the recess is arranged between these corner areas and above the corner area on the edge of the edge web facing away from the formlining. This edge web can thus retain its full width and shape without the width of the entire hollow profile having to be increased to take into account a depression.
  • Embodiments of the frame with respect to the holding web and the recess are the subject of claims 2 and 3.
  • the depression or depressions can be limited and stiffened by a depression profile which is arranged at an opening of the end web and projects into the interior of the hollow profile and which is open to the outside, and the depression profile can have a U-shaped, rectangular, trapezoidal, rounded or V-shaped cross section.
  • a crowbar or chisel finds, as it were, a pocket-shaped recess between the webs of the hollow profile that are approximately horizontal each time it is attached and that depart perpendicularly from the formlining. The forces emanating from this crowbar can be absorbed accordingly.
  • the recess profile can be made in one piece with the web sections and preferably also connected to the webs of the hollow profile or subsequently welded to it.
  • a plurality of wells arranged at a distance from one another, each having a limited length, or else a well extending over the entire length of the respective frame leg can be provided on the end web.
  • Embodiments of the frame, the hollow profile and in particular the recess profile and the recess are the subject of claims 7 to 13. This results in a multitude of possibilities for designing the recesses and the webs forming them so that on the one hand the hollow profile forming the frame is stable and rigid is and on the other hand a good attack for a crowbar is guaranteed, without the edge web must be shortened for this purpose and exposed to strong forces that could deform it over time.
  • the measures of claims 8 and 9 improve the introduction of the forces emanating from a chisel into the end and retaining web.
  • beads and the like in the area of the depressions can contribute to stiffening, which can better withstand the forces exerted by a crowbar.
  • the recess profile with which the recess is covered except for its outwardly extending opening, which is used for the insertion of the crowbar
  • a solution is also possible in which the recesses on the end web penetrate through this web and pass through openings into the interior of the hollow profile are formed, in which at least the edge facing the holding profile, preferably the entire circumference or all edges, are reinforced.
  • the missing inner lining of the recess makes the frame lighter and cheaper in this way.
  • the edge web also advantageously being its greatest possible width in relation can keep to the overall dimension of the hollow profile. Since the reaction forces emanating from the chisel are primarily introduced into the holding web located parallel to the edge web, the risk of permanent deformation of the edge web, which is very important for the tightness of the entire formwork, is practically excluded.
  • the only figure shows a schematic representation a cross section through a frame leg of a frame of a formwork panel sitting on the floor, the hollow profile above the edge web in its area facing away from the formwork skin this has a recess that recesses to attach a chisel, but the edge web has its width corresponding to the largest dimension of the hollow profile transverse to the formlining.
  • a formwork panel generally designated 1, with its lower edge region shown in cross section, has on the edges of its formwork skin 2 a framework, generally designated 3, the individual frame legs of which are formed by a hollow cross section 4 having a closed cross section.
  • the outermost edge web 5 of this hollow profile 4 which runs approximately at right angles to the formlining 2, in each case forms a stop for the frame 3 or stop for a neighboring formwork panel or other formwork element to be connected, such as a formwork corner or the like, so it should be as flat as possible and with a linear cross section be provided and also have the largest possible cross-sectional length for good tightness and fit.
  • a frame leg with this edge web 5 is placed on a floor or other standing surface 6 in order to form a formwork.
  • the hollow profile 4 has in its area facing away from the formwork skin 2 at least one recess 7 projecting in its cross section for the attack of a crowbar 8.
  • this recess 7 is provided adjacent to the outermost edge web 5 in a terminating web 9 running transversely to this edge web 5 and opposite the edge or end 5a of the edge web 5 facing away from the formlining 2 into the interior of the hollow profile 4 is directed and jumps back.
  • the crowbar 8 can engage an upper boundary web 10 of the recess 7 in this position of use, i.e. the edge web 5 and its edge 5a remain undisturbed by the working end of the crowbar 8.
  • the risk of deformation of the edge web 5 is thus avoided and the edge web 5 can have its greatest possible extent in accordance with the cross-sectional width of the hollow profile 4.
  • the edge web 5 and a spaced-apart, in the exemplary embodiment parallel holding web 11 are provided and the recess 7 is arranged or incorporated on or in the transverse web, in the exemplary embodiment running at right angles to these webs 5 and 11, of the hollow profile 4 .
  • the end web 9 has, at the opposite ends or edges 5a or 11a of the edge web 5 and the holding web 11, each of which forms corner sections, the mutually facing edges 9b of which delimit the recess 7 at the opposite ends or edges 5a or 11a of the edge web 5.
  • the depression 7 is delimited and stiffened by an outwardly open depression profile 12 which is arranged at an opening of the end web 9 and projects into the interior of the hollow profile 4.
  • This recess profile 12 has a U-shaped and rectangular cross section. However, it could also be trapezoidal, rounded or V-shaped.
  • the depression profile 12 is connected in one piece to the web sections 9a of the end web 9 and thus also the other webs of the hollow profile 4. But it could also be welded to it later.
  • the training can best be realized with the help of a deepening profile 12.
  • the area of the depression profile 12 facing the holding web 11 is in turn designed as a web 10 which runs at a distance from the holding web 11, in the exemplary embodiment parallel to it.
  • the clear distance between the holding web 11 and this web 10 of the recess profile 12 can be equal to or greater than the cross-sectional thickness of the webs, for example correspond to approximately twice the thickness of the webs. This results in a U-shaped cross-sectional shape at the edge 11a of the holding web 11, which opposes the attack of the crowbar 8 with a desired high resistance and has a high degree of rigidity in order to be able to absorb the forces occurring without any risk of deformation, especially for the edge web 5.
  • the recess 7 in the exemplary embodiment is arranged centrally and symmetrically between the holding web 11 and the edge web 5, there is an analog approximately groove-shaped or U-shaped cross-sectional shape also at the edge 5a of the edge web 5, so that here too the rigidity and thus the Danger of deformation is further reduced.
  • the rigidity of these edge regions 5a and 11a also depends somewhat on how long the web 10 of the recess profile 12 is. The greater the length, the sooner you can in turn, deformations occur primarily on the recess profile 12.
  • the depth of the recess 7 is therefore approximately half as large or even slightly smaller than the distance between the retaining web 11 and the edge web 5 compared to the end web 9 and the edges 5a and 11a facing away from the formlining 2. In the exemplary embodiment, this depth corresponds to the recess 7 about a third of the distance between the retaining web 11 and the edge web 5.
  • the clear distance between the retaining web 11 and the adjacent web 10 of the recess profile 12 could be at least partially filled.
  • stiffening webs or bead-shaped indentations could be provided on one or both webs 10 and 11.
  • knob-shaped deformations could cause mutual support of the webs 10 and 11 and thus a stiffening of the edge area 11a acted upon by the crowbar 8.
  • the cross-sectional length of the edge web 5, starting from the rear of the formwork skin 2, that is to say without the section extending over the narrow side of the formwork skin 2, is equal to that of the holding web 11.
  • the two located at the edges or ends 5a and 11a of these webs 5 and 11 Corner areas of the hollow profile 4 are thus arranged at the same distance from the formlining 2.
  • this cross-sectional length of the edge web 5 is even made larger than that of the holding web 11 and then also the corner region formed with the edge web 5 a greater distance from the formwork skin 2 than the corner region on the landing stage.
  • the edge web 5 can in any case be equipped with such a width or cross-sectional length as is necessary for a tight and precise stop compared to a neighboring formwork panel or another formwork element to be connected. Nevertheless, alignment of such a formwork panel 1, which stands on a floor 6 with an edge web 5, is easily possible with the chisel 8, an attack of this chisel 8 on the edge web 5 being avoided due to the recess 7 which is then higher in the use position.
  • At least one of the corner areas i.e. the transition from the retaining web 11 to the end web 9 and / or the transition from the edge web 5 to the end web 9, can be chamfered or rounded off if this is for reasons of stability or other reasons such as Example of attaching appropriate brackets when connecting frame 3 adjacent formwork panels or the like would be required.
  • an overall rounded transition from the retaining web 11 and / or the edge web 5 into the recess profile 12 can be provided, i.e. the end web 9 or its sections 9a can be designed in an arc shape.
  • the recess profile 12 is missing and the recesses 7 on the end web 9 are formed by openings which pass through this web and which are continuous or open in the interior of the hollow profile 4, in which openings at least the one facing the holding web 11 is formed
  • Edge 9b but preferably the entire circumference or all edges could be reinforced, for example by additional webs welded on. Reinforcement webs clipped inwards could also limit and stiffen such an inward opening 7.
  • the frame 3 of a formwork panel 1 is preferred by one formed a closed cross-section hollow profile 4, the cross section of this hollow profile 4 corresponds approximately to a rectangle. Adjacent to the outermost edge web 5 of this hollow profile 4, but without impairing the length or width of this edge web 5, at least one recess 7 is provided on a profile section or end web 9 extending transversely to this edge web 5, to which a chisel 8 can attach when the edge web 5 stands on a floor surface 6 or the like.
  • the edge web 5 can thus have its greatest possible width in spite of such a depression 7 serving for the attack of a chisel 8 on the hollow profile 4 and is optimally protected from deformations by the chisel 8, so that it remains as a substantially flat and undeformed stop even after prolonged use for a neighboring formwork element is retained.
