Definitions

  • the invention relates to a frame for formwork panels, which is formed by hollow profiles that run on the edges of a formwork skin or formwork panel and have a closed cross-section, the outermost edge web of which runs approximately at right angles to the formwork skin forms a stop for the frame or stop of a neighboring formwork panel, wherein the hollow profile of the frame in its area facing away from the formlining has at least one recess projecting into its cross section for the attack of a crowbar or the like.
  • Such a frame is known from DE-PS 34 29 304.
  • the depression for attacking a crowbar is arranged in the 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.
  • hollow profiles are used as frames in formwork panels, especially 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 is guaranteed even less, at least after repeated aligning and moving with the help of a crowbar.
  • the solution to this seemingly contradictory task consists essentially in the fact that the depression (s) on the hollow profile is (are) provided adjacent to the outermost edge web in a terminating web running transversely to this edge web and is directed into the interior of the hollow profile opposite the edge or end of the edge web facing away from the formlining (are) or jumps back.
  • a recess is provided on the hollow profile forming the frame in order to be able to attack with a crowbar or chisel, but the edge web remains undisturbed by this recess and can keep its full width, since the recess is only within the the edge-circumscribed area is arranged on a cross-piece and thus also keeps most of the reaction forces away from the edge-piece and acts more on a holding piece of the hollow profile located above the cross-piece in the position of use.
  • edge web and a preferably parallel holding web arranged at a distance from it are provided and the recess (s) is or are arranged on or in the end web of the hollow profile which runs transversely, preferably at right angles to these two webs.
  • the corner areas of the hollow profile are preserved according to the invention and the recess is to a certain extent 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 without the width of the entire hollow profile having to be increased to take into account a depression.
  • the end web may have respective web sections forming corners, the mutually facing edges of which delimit the depression (s).
  • This makes an almost box-shaped hollow profile possible, which also has corners or similar shapes on its edge facing away from the formlining to increase the rigidity, between which the depression or depressions can be arranged, so that the reaction forces applied to them, especially in the use position above the recess located web section and also the overlying holding web can be initiated.
  • the actual edge web remains practically unaffected by the reaction forces and, above all, does not experience any permanent deformations.
  • a crowbar or crowbar there is still good contact with the edge web and good tightness with a neighboring edge web.
  • the indentation or indentations can be limited and stiffened by an indentation profile which is arranged on an opening of the holding web and projects into the interior of the hollow profile and which is open to the outside, and the indentation 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 depression between the webs of the hollow profile which are approximately horizontal each time a crowbar is attached and extend at right angles 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 is 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 clad 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 retaining 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 recess has a recess to set a chisel, but the edge web has its width corresponding to the largest dimension of the hollow profile transverse to the formlining.
  • a shuttering panel designated as a whole with 1, with its lower edge region shown in cross section, has on the edges of its skin 2 a frame designated as a whole with 3, the individual frame legs of which are formed by a hollow cross section 4 having a closed cross section.
  • a frame leg with this edge web 5 is placed on a floor or another standing surface 6 in order to form a formwork. So that the formwork panel 1 can possibly be displaced slightly in this position for alignment, 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 closing 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 use position, 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 portions, 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 holding 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 retaining 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 increases 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 result in a 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 formlining 2, that is to say without the section extending over the narrow side of the formlining 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 made even greater than that of the holding web 11 and then the corner region formed with the edge web 5 is at a greater distance from the formlining 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 the attachment of 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 depression 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 case 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 that are clipped inward could also limit and stiffen such an inward open recess 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 substantially 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 protected as well as possible 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.
