[0103] Formwork systems and frame formwork elements and methods for forming a hardenable building material are well known from the general prior art, for which reference is made to DE 10 2018 203 764 A1, for example. Therefore, only the features relevant to the invention will be discussed in more detail below.

[0104] FIGS. 1, 2, 8, and 9 show a frame formwork element 1 for forming a hardenable building material. In the exemplary embodiment, the building material is preferably concrete. However, the invention is not limited to this. The exemplary embodiment is to be understood in such a way that, instead of concrete, another hardenable building material can also be used for forming.

[0105] The frame formwork element 1 shown in FIGS. 1, 2, 8, and 9 has a frame 2 and a formwork shell 3 which is attached or can be attached to the frame 2.

[0106] The frame 2 has at least two frame longitudinal parts 4 and at least two frame transverse parts 5. The outer contours of the frame 2 are each formed in this case by two frame longitudinal parts 4, namely a left and a right frame longitudinal part 4, and two frame transverse parts 5, namely an upper and a lower frame transverse part 5. As shown in FIGS. 1, 8, and 9, further frame transverse parts are arranged between the upper and the lower frame transverse part 5, but these are not designated in more detail. In principle, however, the additional frame transverse parts can also be omitted. Furthermore, it is possible for the frame 2 to have further frame longitudinal parts which run between the two outer frame longitudinal parts 4, namely the left and the right frame longitudinal part 4. In the exemplary embodiment, however, only two frame longitudinal parts 4 are shown or provided. In FIGS. 1 and 8, additional bracing parts, not designated in more detail, are shown, which extend parallel to the frame longitudinal parts 4 and connect the upper frame transverse part 5 or the lower frame transverse part 5 to an adjoining further frame transverse part, not designated in more detail. A configuration of this type can be useful for stiffening.

[0107] The invention and the exemplary embodiment are not to be understood as being limited to a specific configuration of the frame 2 with a specific arrangement or number of frame longitudinal parts 4 and frame transverse parts 5.

[0108] As can be seen from FIGS. 1,2, 8, and 9, it is provided in the exemplary embodiment that at least one transverse bracing 6 is fixed between the frame longitudinal parts 4, said transverse bracing having two transverse braces 7 which run parallel to each other in a mutually spaced manner and between which a through-gap 8 is formed for passing through anchor rods 9.

[0109] In the exemplary embodiment, three transverse bracings 6 of this type are provided as an example. In principle, however, the exemplary embodiment is to be understood in such a way that only one or at least two, preferably three or more, transverse bracings 6 are provided in a frame formwork element 1.

[0110] In the exemplary embodiment, it is provided that at least one guide device 10 for forming an anchor point is inserted into the through-gap 8 which is formed by a transverse bracing 6. In the exemplary embodiment, it is provided that a guide device 10 is inserted into each through-gap 8. In principle, however, it can also be provided that no guide device 10 is inserted into a through-gap 8. Furthermore, it can also be provided that two, three, or more guide devices 10 are inserted into a through-gap 8. The configuration of the through-gaps 8 with one, two, or more guide devices 10 or not using a guide device 10, i.e. not forming an anchor point in the through-gap 8, can be made dependent on the requirements placed on the frame formwork element 1, in particular the pressure requirements and the concrete pattern.

[0111] A particularly suitable guide device 10 is shown in more detail in FIGS. 3 to 7. A guide device 10 of this type is also used in FIGS. 1, 2, 8, and 9. However, the invention and the exemplary embodiment are not limited to the specific configuration of the guide device 10, as shown in FIGS. 3 to 7.

[0112] The guide device 10 is preferably detachably connected to the transverse bracing 6.

[0113] The connection of the guide device 10 to the transverse bracing 6 can take place in a form-fitting and/or material-fitting and/or force-fitting manner. It can preferably be provided for the guide device 10 to be screwed, riveted, clipped, or particularly preferably braced to the transverse bracing 6.

[0114] As shown in the exemplary embodiment, the guide device 10 has an anchor hole 11 for passing through one of the anchor rods 9 and a securing region 12 for securing the guide device 10 to the transverse bracing 6. In FIGS. 1 and 8, it is only shown by way of example that the securing region 12 can be designed in such a way that it has clamping parts 12a in order to brace the guide device 10 to the transverse bracing 6.

[0115] It is preferably provided for the guide device 10 to be secured, preferably braced, to both transverse braces 7 of the transverse bracing 6.

[0116] As can be seen in particular from FIGS. 3 to 7, it can be provided in the exemplary embodiment that the guide device 10 has a conical guide part 13 for passing through the anchor rod 9, said guide part being flush with the anchor hole 11.

[0117] The conical guide part 13 tapers in this case, starting from the securing region 12 in the direction of the front side of the guide device 10. In the region of the front side of the guide device 10, a seal receptacle 14 is provided in the exemplary embodiment. In principle, the seal receptacle 14 can have any desired design. In the exemplary embodiment, it can be provided that the seal receptacle 14 is designed in such a way that a seal 15 is detachably fitted or inserted thereon. In the exemplary embodiment, it is provided that the seal 15 is inserted into the seal receptacle 14. The seal 15 is designed in this case in such a way that it forms a sealing lip that is not designated in more detail.

[0118] The seal 15 can be designed in such a way that it can be detachably connected to the seal receptacle 14, as is shown in FIGS. 3 to 7, in particular in FIG. 7. In FIG. 7, it is shown that the seal 15 is inserted, for example pressed, into the seal receptacle 14 which is the front end of the conical guide element 13. The seal 15 is preferably captively connected to the seal receptacle 14 of the guide device 10. The seal receptacle 14 and the seal 15 are positioned in such a way that the seal 15 seals the conical guide part 13 relative to an anchor bore 16 in the formwork shell 3 when the guide device 10 is correctly installed. The conical guide part 13 is in this case flush with the anchor bore 16.

[0119] In the exemplary embodiment, it is provided that the front end of the conical guide part 13 has a constant diameter, i.e. it is not formed conically. It is provided that the front end of the guide part 13 runs in the anchor bore 16 when the guide device 10 is correctly installed.

[0120] The seal 15 can be formed of any suitable material, in particular rubber, plastics material, or silicone. The seal 15 can also be connected to the seal receptacle 14 in such a way that it is sprayed on or vulcanized on. The seal 15 can also be formed as an integral part of the guide device 10.

[0121] In the exemplary embodiment, it is provided that the guide device 10 is formed in one piece, i.e. the anchor hole 11, the conical guide part 13, the seal receptacle 14, and the securing region 12 of the guide device 10 are made in one piece with each other. Furthermore, it is preferably provided in the exemplary embodiment that the guide device 10 or the aforementioned parts of the guide device 10 are formed of the same material. For this purpose, it can be provided that the guide device 10 is formed of cast steel. However, it is particularly advantageous if the guide device 10 is formed of plastics material.

[0122] In a way that is not shown in more detail, it can be provided in the exemplary embodiment that the anchor bores 16 made in the formwork shell 3 are closed flush with a sealing closure on the side facing the concrete if the anchor bores 16 are not used or if the guide device 10 is not installed or uninstalled. In this case, the sealing closure can preferably be formed as a sealing plug.

[0123] In the exemplary embodiment, in FIGS. 1 and 8, it is shown that the frame longitudinal parts 4 can have a plurality of through-bores 17 for passing through anchor rods 9.

[0124] Furthermore, it is shown in FIGS. 1 and 8 as an example that it can be advantageous if a through-gap 8 is arranged flush between a pair of through-bores 17 which are positioned on different frame longitudinal parts 4 at the same height. An arrangement of this type is shown as an example in the middle of the three through-gaps 8. An arrangement of this type can in principle also be optionally provided for the other through-gaps 8. Of course, the exemplary embodiment is not limited to a through-gap 8 being arranged flush between a pair of through-bores 17.

[0125] In principle, the guide devices 10 can be inserted at any desired position along a through-gap 8 and can be secured to the transverse bracing 6, preferably to both transverse braces 7, of a transverse bracing 6. In the exemplary embodiment, it is shown as an example that the guide devices 10 are positioned centrally in relation to the horizontal extent of the through-gap 8, but the exemplary embodiment is not to be understood as being limited to this. The positioning of the guide device 10 can depend in particular on the requirements, in particular the pressure requirements and the concrete pattern.

[0126] As shown in particular in FIGS. 2 and 9, the guide device 10 preferably has a length which corresponds at least to the depth of a frame 2 of the frame formwork element 1. In the exemplary embodiment, it is provided that the guide devices 10 have a length designed in such a way that a rear end of the guide device 10, on which the securing region 12 is formed, preferably runs in a plane with a rear side 2b of the frame 2, as is shown in principle in FIG. 2. The front side of the guide device 10 extends in this case so far in the direction of the front side 2a of the frame 2 that the front side of the guide device 10, i.e. the front end of the conical guide part 13, penetrates into an anchor bore 16 in the formwork shell 3. This is also shown as an example in FIG. 2 and also in FIG. 9. In this case, the guide device 10 has a length in such a way that the front end of the guide device 10 or, in the exemplary embodiment, the seal 15 placed there, terminates flush with the concrete-contacting side of the formwork shell 3, i.e. the front side 3a of the formwork shell 3. The seal receptacle 14 or at least part of the seal 15 is located in this case within the anchor bore 16 or is positioned in such a way that the seal 15 closes a gap between the front end of the conical guide part 13 penetrating the anchor bore 16 and the inner wall of the anchor bore 16 of the formwork shell 3. This reliably prevents concrete from escaping in this region through the seal 15.

[0127] A formwork system 18 with (at least) two frame formwork elements 1 is shown in principle in FIGS. 8 and 9.

[0128] FIG. 8 shows in this case a plan view of the rear side 2b of the frame 2 of a frame formwork element 1 of the formwork system 18. The frame formwork elements 1 are braced in a mutually spaced manner by the anchor rods 9 inserted into the guide devices 10 according to the invention.

[0129] The formwork system 18 according to FIGS. 8 and 9 has, as an example, six guide devices 10 according to the invention, so that three anchor points are formed in each of the two frame formwork elements 1. This is shown in FIG. 9. The frame formwork elements 1 are positioned in this case in a known manner in such a way that two anchor points, in this case two guide devices 10, are flush with each other. Furthermore, the formwork shells 3 of the corresponding frame formwork elements 1 have the anchor bores 16 already described, through which the associated anchor rods 9 can be inserted.

[0130] In a way that is not shown in more detail, it can also be provided that further anchor rods 9 are also guided through the through-bores 17 in the frame formwork elements 1.

[0131] According to this principle, a plurality of frame formwork elements 1 can be connected to each other in a manner known in principle in such a way that they together form a formwork for forming a hardenable building material, in particular concrete.

[0132] In fact, it is shown in FIGS. 8 and 9 that both frame formwork elements 1 have the guide devices 10 according to the invention. In principle, however, it is also possible for only one of the frame formwork elements 1 to have the guide devices 10 according to the invention and for the anchor point to be provided in the associated second frame formwork element 1 in a conventional manner, for example through a through-bore 17.

[0133] In the case of the formwork system 18 according to the invention, however, it makes sense for all frame formwork elements 1 to be provided with at least one guide device 10 according to the invention.

[0134] As can be seen from FIGS. 8 and 9, anchor fixations 19 are installed on the respective ends of the anchor rods 9. The anchor fixations 19 are formed as nuts in the exemplary embodiment. The anchor rods 9 have in this case a thread at their respective ends, onto which thread the nuts 19 are screwed in order to brace the frame formwork elements 1. This principle is basically already known from the prior art.

[0135] Within the scope of the formwork system 18 according to the invention, anchoring technology that can be operated in a one-sided as well as in a two-sided manner can also be used. Furthermore, the use of spacer tubes or cladding tubes can be provided within the scope of the invention.

[0136] In FIG. 9, a configuration is shown in which the anchor rod 9 runs conically, i.e. the anchor rod 9 tapers starting from one end to the other end, so that the use of spacer tubes can be dispensed with in a known manner.

[0137] In order to facilitate the use of anchor fixations 19, it is provided in the exemplary embodiment that the guide device 10 has an anchor bore 20 which serves to insert a part of the anchor fixation 19, generally an eyebolt of the anchor fixation 19, said eyebolt not being shown in more detail.

[0138] A set of guide devices 10—not shown in the exemplary embodiment—can be provided in the formwork system shown in FIGS. 8 and 9, wherein the set has different guide devices 10 for different types of anchor rods 9.
