Definitions
- the invention relates to a concreting panel, which provides a formwork surface with its front side, and to a connected arrangement of a plurality of these concreting formwork panels.
- a particularly widespread type of concreting board is the so-called frame formwork.
- a frame formwork usually consists of a rectangular frame made of metal carriers, which is further stiffened by longitudinally and / or transversely extending intermediate carriers, and a formwork connected to the frame, typically made of a plywood board. The mentioned carriers are welded together.
- the supporting function or support structure of the formwork panel is essentially taken over or formed by the possibly stiffened frame, whereas the formwork skin forms the formwork surface with its one side, without substantially assuming support function.
- the known frame formworks have a comparatively high weight per square meter of formwork surface.
- these different formats must be delivered to the construction site in at least the required number and stored there until they are used.
- the logistics are elaborate, which is especially true for less popular formats.
- the manufacturer of the frame formwork shows similar difficulties. In particular, a considerable number of different frame formwork formats must be manufactured in different ways.
- the invention has for its object to make a concreting board available that can be produced more efficiently in different formats.
- the formwork panel according to the invention is easier to repair even in the event of damage than conventional panel formwork, be it at the construction site or at the manufacturer's plant.
- Many embodiments of the formwork panel according to the invention have the potential to be more economical and easier per square meter of formwork area than conventional formworks.
- the subject matter of the invention is a concreting panel which, with its front side, offers a formwork surface, with the following features:
- the formwork panel is composed of detachably interconnected formwork panels
- the panel elements include a first edge support and a second edge support extending along two opposite edges of the formwork panel;
- the panel elements include filler members each extending from the first edge support to the second edge support;
- the filling elements are both part of the supporting structure of the formwork panel, as well as, each with its front side, part of the formwork surface of the formwork panel. Due to the invention, it is possible to assemble a spectrum of different panel formats from a comparatively small number of different panel members. In particular, it is possible to produce edge beams in a few different standard lengths, to produce filler elements in only one or a small number of different standard lengths (the filler element length extends when the shuttering panel is assembled at right angles to the longitudinal extent of the edge beams) and from these panel elements the concrete desired Assembly panel sizes in the desired number.
- part of the formwork surface of the formwork panel is not intended to exclude that the filling elements are covered by a thin film or a paper as a protective and wear-inhibiting layer, which has only a minor auxiliary function. Since the filling elements are both part of the support structure and part of the formwork surface of the formwork panel, there is a fundamental, constructive weight advantage of the formwork panel according to the invention in comparison to conventional frame formworks.
- the formwork panel according to the invention it is possible to assemble the formwork panel according to the invention from the panel elements, in particular either at the manufacturer's plant or in a center serving a larger territory (eg 10 to 20 centers for Europe), or at the construction site. especially in the case of a construction site that requires a large number of formwork panels.
- a construction site that requires a large number of formwork panels.
- the edge beams are longer than the filler elements (with a perpendicular extending to the two Randträ- length), so that the edge beams bridge the longer longitudinal dimension of the formwork panel and the filling elements bridge the shorter transverse dimension of the formwork panel.
- the filling elements must absorb insofar only a lower bending moment between the first and the second end of their length than the edge support, which is why preferably the edge supports are formed so that they can absorb a higher bending moment than the filling elements.
- marginal beams which are shorter than the filling elements, especially for less frequently occurring formats.
- the filling elements are connected to the two edge beams by means of mechanical connecting elements.
- Cheap mechanical fasteners are screws, even screws with self-tapping threads, and rivets.
- To solve rivets can z. B. remove the rivet head with a pair of cutting pliers from the rest of the rivet.
- Other mechanical fasteners are possible, for. B. collapsing elements.
- the filling elements cover a peripheral support or the two edge support on the front side to a greater or lesser extent, preferably completely cover. In this way, one can come to an education in which the formwork surface of the formwork panel is provided substantially exclusively by the filling elements, so that there are no shocks between the edge support and Guelement-front side, which may be apparent in the finished concrete, and so that the formwork panels are easier to remove from the solidified concrete.
- the two edge beams each have a cross section in the manner of a double-T profile.
- Double-T profiles have a particularly good material utilization. It is in the hand, the two flanges of the profile in their material thickness and in their width in such a way that the profile has the desired moment of resistance to bending. In some training cases, it is a convenient way to form the middle web of the profile as a hollow web, so that the cross section of the profile is closer to a rectangle, possibly with a widened head and widened foot.
- the two edge supports are each formed on their side facing the filling elements with a longitudinal projection, which is designed for engagement with a connection lock for connecting two adjacent formwork panels.
- the edge beams are each formed with a series of engaging holes each formed for engaging with a claw of a connecting lock for connecting two adjacent shuttering boards. This longitudinal projection or these engagement openings preferably sit adjacent to the back of the formwork panel. In such formed edge beams can work with connecting locks of the structure, as they are used for conventional frame formwork.
- the two edge supports each have at least one half-hole in their edge region facing away from the filling elements, which extends at right angles to the formwork surface.
- the half-hole is supplemented by a corresponding half-hole of an edge support of an adjacent formwork panel to form a complete hole.
- a tension anchor may be inserted through a mutually spaced pair of formwork panels (manufacture of a concrete wall having a thickness equal to the distance between the formwork surfaces of the two formwork panels) and fixed to the form panels in the spacing of the formwork panels.
- the tension anchor can be passed through holes in the middle area of the edge girders.
- the edge beams have a hollow profile cross-section) or through holes in the area where edge support and filling element abut each other are passed.
- the two edge beams each have a length corresponding to an integer multiple, the same Greelementbreiten within the formwork panel.
- the edge support and the filling elements can be combined particularly well with each other.
- the edge member lengths are an integer multiple of the panel width (which is either equal to the filler length or equal to the filler length plus two times a portion of the width of each edge carrier or equal to the filler length plus two edge carrier widths). In this way, at a line formed by the transverse ends of a plurality of adjacent formwork panels, another formwork panel can be connected in a 90 ° rotated orientation.
- all filling elements are formed substantially equal to each other.
- At least the two end-filling elements each have a side wall in the edge region of the formwork panel and these side walls are each formed on its side facing the panel center with a longitudinal projection, which is designed for engagement with a connection lock for connecting two adjacent formwork panels.
- at least the two end-filling elements each have a side wall in the edge region of the formwork panel and these side walls are each formed with a series of engagement openings, which are each designed to be engaged with a claw of a connection lock for connecting two adjacent formwork panels.
- This longitudinal projection or these engagement openings preferably sit adjacent to the back of the formwork panel.
- end-filling elements can work with connecting locks of the structure, as they are used for conventional frame formwork.
- the longitudinal protrusions or engagement openings of the filling elements mentioned in the preceding paragraph are preferably of substantially the same design as the longitudinal protrusions or engagement openings of the edge supports mentioned earlier. This optimizes the possible uses of the connection locks. It is even more favorable if, in addition, the edge supports and at least the end filling elements in their edge region facing away from the panel center, in each case on the back, substantially the same flange width, optimally even substantially the same profile cross section not only at the rear region but also for a further subsequent Part of the height, have.
- the filling elements each have openings for cooperation with formwork accessories, z. As directional supports and consoles on.
- the filling elements each have at least one handle opening in at least one side wall. Particularly favorable are at least one handle opening in each case in those side walls that do not connect to edge support.
- the filling elements each have stiffening ribs on the back of the wall forming the scarf surface. In the case of filling elements made of injection-molded plastic, a pattern of intersecting stiffening ribs running obliquely to the filling element edges is particularly favorable in terms of a good stiffening effect with the lowest possible material consumption.
- Edge beams made of metal are preferred because of the high strength and the good ratio of strength to price.
- Metallic edge supports can be produced in particular by rolling, edges of sheets and extruding.
- Particularly preferred metals are steel and light metal or aluminum (the term "aluminum" throughout the application covers both the very rare case of pure aluminum and aluminum alloys.)
- Edge extruded aluminum extrusions are inexpensive to produce, light and corrosion resistant.
- edge supports made of plastic, particularly preferably fiber-reinforced plastic.
- Metal and, preferably fiber-reinforced, plastic are also the preferred materials in the filling elements.
- Metallic fillers can be made by edges of sheet metal, extruding or casting. Again, light metal or aluminum are particularly favorable.
- injection-molded filling elements are particularly preferred because they can be produced rationally in consistent quality and in high numbers.
- a fiber reinforcement is preferably selected in which the sufficiently short reinforcing fibers can be introduced into the mold cavity during injection molding. Very particular preference is given to the material combination edge support made of metal (preferably extruded aluminum profiles) and filling elements made of plastic (preferably fiber-reinforced and injection-molded).
- the plastic in the formwork panel according to the invention can be selected from a wide range of suitable on the market. Only as an example in a A whole range of suitable plastics is polypropylene with fibers (which are short enough so as not to impair the injection molding ability) and optionally with additives. First and foremost are glass fibers and carbon fibers.
- the formwork panel - apart from about the mechanical fasteners - is constructed only of the edge beams and the filling elements, it is quite possible for certain requirements, also on the other two edges of the formwork panel edge support provided, thus run parallel to the longitudinal direction of the filling elements.
- These additional edge supports may be releasably connected to the two mandatory edge supports, preferably by means of mechanical fasteners. It is preferred to construct the formwork panel according to the invention according to the modular grid principle.
- a typical grid R can be 30 cm. Then you can run the filling elements with a width R; for the edge beams can then give a length of n x R.
- the length of the filling elements is made so large that, assembled with the two edge supports, a panel width of m ⁇ R results. Then the lengths and widths of the formwork panels fit well together. Particularly favorable grid dimensions are in the range 20 to 40 cm. n and m are integers greater than zero.

- FIG. 4 also shows cover caps 20 for the ends of the edge supports 4.
- the best in Fig. 4, 7, 8 recognizable profile cross-section of the filling elements 6 could be referred to as U-shaped with inner, obliquely extending snap bars 22.
- the snap-lock bars 22 approximately triple the formwork surface 8 and approximately halve the overall height at the side walls 30; they stiffen and optimize with the location of the screw channels 32, the derivative of the forces in the edge support.
- the middle leg 24 of the U is part of the formwork surface 8 with its front surface.
- the two other legs of the U have at the rear end of the filling element 6 a flange 26 protruding on both sides in greater material thickness and on the front side a flange 28 of larger material thickness projecting on one side.
- Each edge support 4 is provided with a series of holes 34, each extending transversely across the outer web 14 and the inner web 16, wherein the bore diameter in the outer web 14 is greater. Screws 40 can be completely inserted through their respective bore 34 in the outer web 14, together with their head 42 from the outside, and then, with the exception of their head 42, are inserted through the bore 34 in the inner web 14. Then you can grab with a tool through the hole 34 in the outer web 14 and screw the screw in question 40 in a screw 32 of a filling element 6. Each built in the formwork panel 2 filling element 6 is thus screwed by two screws 40 with the one edge support 4 and by means of two screws 40 with the other edge support 4. Accordingly, it is proceeded with all filling elements 6.
- the described connection between respective filling element 6 and respective edge support 4 is a very easily created and re-releasable connection. binding. By means of caps 44, the holes 34 in the outer side wall 14 can be closed after successful assembly of the formwork panel 2.
- the front surfaces of the filling elements 6 and (of the front flange 10 of the) edge carrier 4 lie on a common plane and together form the shuttering surface 8 of the shuttering board 2.
- the mutual contact of the filling elements 6 against each other and the filling elements 6 against the edge supports 4 is so narrow that essentially no concrete can pass when performing the concreting work.
- the outer edges of the flanges 26 and 28 of the side walls of the filling elements 6 contact the corresponding outer edge of the flanges 26 and 28 of the adjacent filling element 6.

Then, the claws 57 may conveniently enclose between them a marginal support or two sidewalls of filling elements in part. Also, the later to be performed engagement in engaging holes in side walls of filling elements is thus easy to accomplish.
- edge supports 4 are formed at their rear flange on the side facing the filling elements 6 with a longitudinal projection 46.

It is a series of spaced apart in the longitudinal direction of the edge support 4 half-holes 62. If one has attached to a formwork panel 2 another formwork panel 2 with aligned filling elements 6 and clamped, for example by means of connecting locks 50, two half-holes 52 complement each other to a solid hole. A full hole in the front flange 10 is in each case aligned with a full hole in the rear flange 12.
- the clamping anchor 60 is essentially a threaded rod.
- an anchor plate 64 is placed at the back of the pair of formwork panels 2. Screwed. For example, if you want to build a wall formwork two of the drawn in Fig. 6 Schalkan arrangements with a certain distance therebetween, you have to extend the clamping anchor 60 down in Fig. 6 and imagine screwed there with another pair of Schafel.
- Fig. 7 it is shown how one can attach a (70 shown above cut) console 70 to a panel 2.

- the formwork panel consists - apart from small parts - of two edge beams 4 and 6 filling elements.
- the edge support 4 are, as in the first embodiment, extruded aluminum profiles (where the term "aluminum” also includes aluminum alloys). In deviation from the first embodiment, however, the profile cross section of the edge support 4 is a double-T profile and is not a hollow profile. Each bore 34 passes only through a "wall" of the profile, namely the central web. Caps 4 are not required.

- Each filling element 6 is a unitary injection molded part made of glass fiber reinforced plastic.
- Each filling element has by and large the shape of a box open on one side, wherein the longitudinal walls occupy the full height h of the Wenna fei 2, whereas the transverse walls 102, starting from the front of the filling element 6 occupy only about 70 percent of the overall height h.
- 9 shows a pattern of stiffening ribs 104 that run obliquely relative to the walls 100 and 102 and that intersect at right angles and that are integrally formed on the rear side of the front wall 106 of the filling element 6.
- the filling element 6 is designed for injection molding in such a way that the part of the injection mold positioned inside the box can be pulled out in a direction perpendicular to the formwork surface 8 and the outer side surfaces of the box are formed by parts of the injection mold which respectively extend in the direction to move away from the box interior.
- the screws 40 are not screwed directly into the material of the filling elements 6. Rather, e.g. rectangular threaded plates 108 having a central opening 110, which are inserted by small slots 112 in the longitudinal walls 100 of the relevant Greele- element 6 cross. In front of the opening 110 of the relevant tab 108, there is a pair of half openings 114, each formed in the end region of the transverse wall 102 of the two adjacent filling elements. Through the solid hole thus formed, the screw in question 40 can be screwed into the opening 110 of the tab 108.
- Another difference from the first exemplary embodiment is that between each filling element 6 on the one hand and each of the edge supports 4 connected thereto on the other hand and in each case between adjacent ones
- Filling elements 6 means in the direction of the height h of the formwork panel 2 effective are present for positive fixing of the respective relative position of the adjacent components.
- each Eckausbianache 120 are present, which extend in the transverse direction of the filling element.
- the corner recesses 120 are present at the location of the transition from longitudinal wall 100 to transverse wall 102; between the two longitudinal walls 100, the respective transverse wall 102 is anyway a bit lower, so that they do not have to have corner recess 120 at the top.
- the Eckausströmskyisme are present both on the front side and on the back of the filling element 6.
- the openings 124 pass through stiffening ribs 148, which are respectively present at this point on the outside of the longitudinal wall 100.
- the shear pins 122 may also be tubular hollow pins. In this case, one can push through a bolt here, which is longer than the hollow pin, see Fig. 14b. Alternatively, one could work with interlocking mating of longitudinal projections and longitudinal recesses on the longitudinal walls 100 of adjacent filling elements.
- the described means for the positive fixing of relative positions are designed such that, in particular on the front side of the formwork panel 2, the formwork surface without height level merges without offset from the front surface of the relevant filling element into the front surface of the adjacent filling element 6 or into the adjoining front surface of the connected edge support 4 ,
- the edge beams are cut here for the purpose of clarity and drawn too short.
- the edge support 4 are cut through after two filling elements and also cut off left-top; in truth, they extend further to the left-up.
- each of the rear flange 12 of the edge support 4 has the same width b as each side wall 100 of the filling element 6 in the rear end region.
- FIGS. 12 (console) and 13 (directional support) the situation is quite analogous to FIGS. 7 and 8, although the attachment to the longitudinal wall pairs of the filling elements 6 is effected by angle bolts 132 inserted from above, instead of by jaws 80 The angle bolts 132 are inserted into openings 124 already mentioned, which are present in the longitudinal walls 100 of the filling elements 6.

- a second connecting lock 50b which connects two adjacent formwork panels 2c and 2d to one another, in that the second connection lock 50b clamps two adjacent filler element side walls 100 together.
- the connecting locks 50a and 50b are equal to each other.
- the base 140 is long enough that it is supported with its end regions in each case on a next-coming filler element side wall 100.
- the four jaws 57 engage in four elongated engagement openings 136 in the side walls 100, wherein in the respective side wall 100, the engagement openings 136 are provided in pairs corresponding to the position of the jaws 57.
- connection lock 50b Along the side wall in question are provided a plurality of pairs of engagement holes 136 at those locations where stiffening ribs 148 are so as to have selection in the mounting location of the second connection lock 50b.
- the claws have inclined surfaces 56 as shown in Figs. 5 and 10; cooperating with the end not far from the rear end of the side wall 100 of the respective engagement opening 136, the jaws 52 and 54 bias the two side walls 100 engaged and press the two rear end portions against the base 140 for height alignment.
- a third connection lock 50c is shown in each case.
- Each third connecting lock 50c connects the first switching board 2a to the third switching board 2c and the second switching board 2b to the fourth switching board 2d by an edge support 4 of the Wenna- fei 2c and 2d with a filler sidewall 100 at the end of the adjacent board 2a and 2b are clamped together.
- the connecting locks 50a, 50b, 50c are equal to each other.
- the base 140 rests on a pair of side walls 100 in the rear end region thereof; the claws 57 sandwich the two side walls 100 in the rear end portion thereof.
- the base 140 is long enough so that it rests in its end region on the next side wall 100 in its rear end region.
- One of the jaws 52 and 54 engages behind / engages with their two claws 57, the rear flange 12 of the respective edge support 4.
- the two jaws 57 engage in a pair of engagement holes 136, as in the example of the second connection lock 5b described above.
- FIG. 14 a shows a console 70, a directional support 90 and clamping armature 60.
- inter-engaging longitudinal projection on the edge support 4 or on side wall 100
- engagement openings 136 are alternative means for cooperation with a connection lock 50. Depending on which means are more practicable, the designer can choose. Engagement openings 136 may also be provided in the first embodiment shown in FIG. 1 to 8.
- Fig. 14b the possibility is shown graphically that instead of the connection locks 50 of Fig. 14a bolts 142 with an axially extending slot provided, in each of which a wedge 144 is inserted.
- the wedge 144 is driven so far into the slot that either two edge support 4 or two side walls 100 or a rim support 4 and a side wall 100 between the bolt head and the wedge 144 are clamped together.
- the respective pin 142 is defined by a pair of openings 124 (or, more concretely, by the hollow pin 124, which in this sem pair of openings 124 inserted) inserted therethrough.
- the bolt 142 is inserted through a pair of openings 146 in two adjacent edge beams.
- the bolt 142 passes partly through an opening 124 and partly through an opening 146.
- connection locks 50 or bolts 142 with wedge 144 or bolts can be used alternatively and depending on current requirements.
- the compounds can be solved again immediately after completion of the respective concreting task, or it is also possible to keep several formwork panels 2 connected to one another for an extended period of time, e.g. if you have a larger length of shuttering that was not available at the site, composed of two or more shorter formwork panels 2 and this larger formwork length is later needed again at a different location on the site.
- At least the smaller to medium formats of the formwork panel 2 according to the invention can be made available with such a low weight that a single man can pick them up and carry them to the installation site in the overall formwork. This usually applies to a limit of 40 kg. It has been determined that e.g. can represent a 60 cm wide and 270 cm long board 2 in the construction of the second embodiment of FIG. 9 to 13 with a weight less than 40 kg.
- connection lock 50 or a bolt 142 or a bolt is to be attached, on the inside (ie in the "inside" of the box shape of the filling element 6) to underlay a stiffening element, e.g. a metal strip.
