DETAILED DESCRIPTION OF THE DRAWINGS
[0074] FIG. 1A shows a preferred embodiment of a frame formwork element 100 which comprises a frame 102, which is formed from four edge profiles 101, and a web bracing of horizontally and vertically extending rungs 108. Each of the four edge profiles 101 is designed as a hollow profile. All edge profiles 101 also have the same cross-section. This is shown enlarged in FIGS. 1B to 1D for the upper edge profile 101 (FIG. 1B), the two lateral edge profiles 101 (FIG. 1C) and the lower edge profile 101 (FIG. 1D). Accordingly, all four edge profiles 101 have an essentially rectangular cross-section with a kind of collar as edge protection 111 for a formwork skin 110 (analogous to FIG. 3C). Furthermore, each edge profile 101 comprises a first profile section having a groove-forming fastening corrugation 107 which extends in the longitudinal direction of the profile and a second profile section having two groove-forming reinforcing corrugations 105, 106 which also extend in the longitudinal direction of the profile. The first reinforcing corrugation 105 lies exactly opposite the fastening corrugation 107 and also has the same cross-sectional shape. This is trapezoidal. The other reinforcing corrugation 106, on the other hand, has a V-shaped cross-section.
[0075] The edge profiles 101 of the frame 102 are arranged in such a manner that the profile sections having the one fastening corrugation 107 form a frame inner side 103 and the profile sections having the two reinforcing corrugations 105,106 form a frame outer side 104 of the frame 102. Since the edge profiles 101 are connected by means of a miter 112, a circumferential fastening corrugation 107 is formed on the frame inner side and two circumferential reinforcing corrugations 105, 106 are formed on the frame outer side.
[0076] The frame formwork element 100 shown in FIG. 1A can be combined with a batten 200 in a frame formwork system 300 (see FIGS. 3A to 3C). A preferred embodiment of a batten 200 of different widths b1-b3 is shown in FIGS. 2A to 2D. The battens 200 are also designed as hollow profiles, analogous to the previously described edge profiles 101. They have two profiled side faces 205, 206 and two end faces 207, 208 which connect the side faces 205, 206. The cross-sectional shape of the battens 200 shown is thus essentially rectangular, if the profiling of the side faces 205, 206 is disregarded. It is noticeable that the profiling of the side face 206 corresponds to the profiling of the frame outer side 104 of the frame 102 of the previously described frame formwork element 100, and the profiling of the side face 205 is formed in exactly the opposite manner. This means that the battens 200 can be coupled to one another as well as to the frame 102 of the frame formwork element 100. When two battens 200 are coupled, projecting geometries 201, 202 on the side face 205 engage in the groove-forming reinforcing corrugations 203, 204 of the coupled batten 200, so that a positive fit is achieved. Such a coupling of the three battens 200 shown can be seen in FIG. 2D. Similarly, each of the battens 200 shown can be coupled to the frame 102 of the frame formwork element 101 of FIG. 1A.
[0077] FIGS. 3A to 3C show a first frame formwork system 300 in accordance with the invention, having two frame formwork elements 100 according to FIG. 1A and three battens 200 according to FIG. 2D. The two frame formwork elements 100 are coupled to one another by means of the three battens 200 (see in particular FIGS. 3B and 3C). In this manner, in addition to the coupling of the frame formwork elements 100, a length compensation can be achieved at the same time. While the left-hand batten 200 engages positively in the edge profile 101 of the left-hand frame formwork element 100, the right-hand batten 200 forms two cavities 209 together with the edge profile 101 of the right-hand frame formwork element 100 (see in particular FIG. 3C). Sealing elements (not shown) can be inserted into these cavities 209 so that no water can escape via the joint area. At the same time, a coupling can be achieved by means of the sealing elements, which counteracts a relative movement of the coupled elements.
[0078] As can be seen in particular in FIG. 3C, the frame formwork elements 100 each have a formwork skin 110 which rests on the respective frame 102 and is flush with the edge protection 111 of the edge profiles 101 of the frame 102.
[0079] FIGS. 4A to 4D show further battens 200 for a frame formwork system 300 according to FIG. 3A. These differ from one another by different widths b1 to b4, wherein each batten 200 has a variable width over the entire depth f of the batten. In the case of the batten 200 shown in FIG. 4A, the width b1 increases over the depth f, so that it has a width b1+ at the other end (the projecting geometries 201, 202 and the groove-forming reinforcing corrugations 203, 204 are not taken into account when determining the width). The batten 200 of FIG. 4C is designed analogous to the batten 200 of FIG. 4A, but has a smaller overall width b3, which increases to the width b3+. The opposite is true for the batten 200 in FIG. 4B and FIG. 4D. Here the width b2 or b4 decreases to a width b2 or b4. With the aid of the battens 200 shown, bucklings and/or curvatures can be created in the plane of the formwork skin 110, as shown as an example in FIGS. 5A and 5B. The course of the wall section which is to be produced can be influenced in this manner. In particular, a convex course (FIG. 5A) or a concave course (FIG. 5B) can be specified. Instead of the two battens 200 shown, only one or more than two battens 200 can be used. Furthermore, different battens 200 can be used.
[0080] Another preferred batten 200 for a frame formwork system 300 in accordance with the invention can be seen in FIGS. 6A and 6B. The batten 200 is used for positioning a frame formwork element 100 and is arranged for this purpose under the frame formwork element 100 or on the respective substrate. Due to the changed position of the batten 200, the original width now corresponds to the height of the batten. The batten 200 is placed on the substrate with the projecting geometries 201, 202 pointing upwards and is fixed in the substrate with the aid of fastening means 211 in the form of screws (see FIG. 6C). For receiving the fastening means 211, the batten 200 comprises a lowered area 212 in the area of the projecting geometry 201 with an opening 210 in the form of an elongated hole (see in particular FIG. 6B). The lowered area 212 ensures that the fastening means 211 does not protrude beyond the projecting geometry 201 of the batten 200. Since this would impair the positive fit between the batten 200 and the frame formwork element 100.
[0081] As shown as an example in FIG. 7, two such battens 200 can be arranged in a mirrored arrangement, at a distance from one another on the substrate and fixed. The distance is determined by the thickness of the wall section which is to be produced. A frame formwork element 100 can then be placed on each of the two battens 200 so that the projecting geometries 201, 202 of the battens 200 engage in the corresponding groove-forming reinforcing corrugations 105, 106 of the respective frame formwork element 100. In this manner, a positive fit is achieved between the battens 200 and the frame formwork elements 100, which prevents the concrete placed between the two frame formwork elements 100 from pressing them apart when concreting the wall section which is to be produced. However, this presupposes that the battens 200 are not pressed apart either.
[0082] To counteract this, the two battens 200 can be connected by means of tension straps 213 -as shown as an example in FIGS. 8A to 8D. The tension straps 213 each have an opening 215 in the form of an elongated hole at their two ends for receiving locking bolts 214 (see FIG. 8B), by means of which the tension straps 213 can be connected to the battens 200. Instead of the locking bolt 214, the fastening means 211 in the form of a screw can also be used, with the aid of which the batten 200 can be anchored in the substrate at the same time.
[0083] A preferred locking bolt 214 is shown as an example in FIG. 9B. It comprises an elongated head 216 which is aligned transversely to the longitudinal direction of the batten 200 when it is inserted into the opening 215 of the tie strap 213 and is then twisted so that it is aligned parallel to the longitudinal direction of the batten 200. The locking bolt 214 is inserted analogous to the fastening means 211 into an opening 210 of a lowered area 212 of the batten 200 (see FIG. 9A). This ensures that the locking bolt 214 does not also protrude beyond the projecting geometry 201 of the batten 200. Rotating the locking bolt 214 so that the elongated head 216 is aligned parallel to the longitudinal direction of the batten 200 further ensures that it remains completely behind the projecting geometry 201 (see FIGS. 9C to 9E). The positive fit between the batten 200 and the frame formwork element 100 is therefore not compromised.
[0084] FIG. 10 shows another frame formwork system 300 for producing a wall section in concrete construction. The frame formwork elements 100 are each positioned by means of battens 200 on the base side and held at a distance which corresponds to the thickness of the wall section which is to be produced. As previously described, the battens 200 are fixed to the substrate by means of fastening means 211 in the form of screws. The distance between the battens 200 is maintained by tension straps 213, each of which is connected to the battens 200 by means of locking bolts 214. Neither the fastening means 211 nor the locking bolts 214 project beyond the projecting geometries 201 of the battens 200, so that these engage positively in the corresponding groove-forming reinforcing corrugation 105 of the respective frame formwork element 100. The frame formwork elements 100 are thus positioned over the base-side battens 200 and held at a distance.
[0085] A plurality of tie holes 109 are provided in the vertical rungs 108 of the frames 102 of the frame formwork elements 100. These are also formed in the respective formwork skin 110. Thus, anchor tie rods 302 can be inserted into the tie holes 109 and enable two opposing frame formwork elements 100 to be braced together (see as an example FIG. 12).
[0086] In addition to the battens 200 for positioning the frame formwork elements 100, the frame formwork system 300 shown in FIG. 10 also comprises battens 200 for coupling two adjacent frame formwork elements 100. In this case, the coupling is achieved with the aid of two coupled battens 200 of different widths.
[0087] FIG. 11 shows another framed formwork system 300, which largely corresponds to that of FIG. 10. Here, however, two framed formwork elements 100 are coupled by means of three coupled battens 200 of different widths.
[0088] As shown as an example in FIG. 12, after positioning the frame formwork elements 100 on the battens 200, the frame formwork elements 100 can be vertically aligned and additionally supported with the aid of a push-pull prop 301. Furthermore, an anchor tie rod 302 is inserted respectively into a centrally arranged tie hole 109 of a frame formwork element 100 and said anchor tie rod is used to absorb horizontal loads. Further anchor tie rods 302 can be omitted, since both the base-side battens 200 are connected by means of tension straps 213, as well as further battens 200 which are arranged on the frame formwork elements 100 (see in particular FIG. 13).
[0089] FIG. 14 shows a frame formwork system 300 which has been stacked. This means that the frame formwork elements 100 are not only arranged next to one another, but also one above the other. For coupling, in turn battens 200 are used, whereby two battens 200 are arranged one above the other and coupled with the frame formwork elements 100. The lower batten 200 is connected to an opposite-lying lower batten 200 by means of tension straps 213, the upper batten 200 is connected in a corresponding manner to an opposite-lying upper batten 200. With the aid of the upper batten 200, the frame formwork element 100 which is placed thereon can be positioned and held. The stacked area is vertically aligned and supported by means of a further push-pull prop 301.
