Definitions
- the invention relates to a rail that can be embedded in concrete beams or the like, according to the preamble of the independent claims 1 to 3.
- the rail can either be used as a fastening rail, for. B. to hold trapezoidal sheets or as an anchor rail for carrying in particular facade panels.
- Corresponding anchor channels are also known in the form of toothed channels. If trapezoidal sheets are to be fixed, this is done by means of screws, setting bolts, etc., which can be screwed into the back of the mounting rail and dig into a soft layer of the mounting rail of the concrete beam or the like.
- anchor rails with a C-shaped cross-sectional profile are used to hold facade panels or to connect forces.
- the anchor channel is filled with a layer of soft material that is removed after the concrete has hardened, creating the necessary space for the hammer-head screws or hook-head screws to be used.
- the anchor spacing is greater than 400 millimeters. This relatively large anchor spacing means that an anchorage has to be added retrospectively when the cut-off is produced on site. This is not only associated with a considerable amount of work, but also leads to a severe impairment of the corrosion protection if a hot-dip galvanized design is selected.
- the anchors sitting on the rail should also be suitable for deriving loads in the longitudinal direction of the rail. Such stresses occur, for. B. on if roof surfaces are designed as stiffeners for building stiffening.
- the object of the invention is based on the task of designing a rail of the type in question in a technically simple manner in such a way that on-site cutting to length can advantageously be carried out, without the need for reworking, and that high loads can be absorbed in the longitudinal direction of the rail.
- an anchor spacing of z. B. Provide 150 millimeters. This small anchor spacing always allows the rails to be properly anchored, even when fixed dimensions are cut to length, without special additional measures having to be taken. Furthermore, such a small distance of z. B. 150 millimeters also useful with regard to the stirrup reinforcement arranged in the concrete parts in order to insert the as freely as possible Ensure rails.
- stirrup reinforcements are also arranged at a distance of 150 millimeters, so that there is the possibility of arranging the anchors seated on the fastening rail in each case between the reinforcement stirrups.
- the configurations according to the invention are also particularly suitable for deriving loads in the longitudinal direction of the rail due to the sufficient rigidity present in the direction of stress.
- a design is selected in which an anchor is only attached to one longitudinal side of the rail and has a substantially V-shaped anchor contour. The anchors are fixed to the rail in such a way that the V-apex of the armature of the rail is turned away.
- the anchors are given a triangular shape, which ensures high rigidity in the event of stresses occurring in the longitudinal direction of the rail.
- a bow-shaped design of the anchors is also possible, specifically with the bow apex lying away from the rail.
- the anchor can have a different bow shape. It can be V-shaped, rectangular or even wavy.
- a small anchor spacing can always be achieved, which can also be produced in a cost-saving manner. It makes sense to manufacture the anchor brackets from curved round steel and to weld the bracket leg ends to the rail. Resistance spot welding is particularly suitable. This can be created cost-effectively and also brings sufficient strength.
- the anchor brackets can also be formed by a continuous rod in a corresponding wave form and having several anchors lying one behind the other. Round steel is also used for the rod. Its surface can still be profiled for improved embedding.
- a waveform can be realized in the bending of the round steel bar that a straight intermediate section extending in the longitudinal direction of the rail extends between two anchor bends. In this way, the anchors can be assigned to the rail particularly firmly.
- a stiffening wire can be used parallel to and at a distance from the rail, which connects the stirrup legs at a medium length.
- the higher load-bearing capacity is generated in a simple manner in that the side plate on the comb-like edge at least in sections, for. B. forms angled or dent-shaped anchor projections.
- the anchors for their part can be welded to the edge of the mounting rail designed as flat strips.
- a flat strip as a fastening rail is possible due to the small anchor spacing, so that the profile of the fastening rail itself no longer has to have a high degree of inherent rigidity.
- a foam strip attached to the underside of the flat strip as a layer of soft material. Wood would also be conceivable as a soft material layer. Hollow bodies or composite bodies could also be used. The layer can preferably be attached by gluing. The determination of the z. B. on both sides of the foam strip extending side panels is done Angles of the same. These step flat against the underside of the flat strip and are held there by welding, preferably resistance point welding.
- a U-shaped profiled rail serving as a fastening rail can also be used.
- the corresponding filling can be foamed in continuously using a continuous filling system.
- Separately prefabricated rectangular strip elements can accordingly be omitted. Since the rail back of such a fastening rail is flush with the surface of a concrete beam, the anchors are to be fixed to the U-legs in such a way that they protrude above them and are therefore embedded in the concrete beam.
- the anchors themselves can have different shapes.
- the rail can then be created as an anchor rail with a C-shaped cross section. In this case, the anchors are fixed on the rail side walls running at right angles to the rail back in such a way that they project beyond the rail back.
- the longitudinal slot formed by the C-profile is flush with the corresponding concrete structure after concreting, while the anchors protrude into it and contribute to a firm embedding of the anchor rail.
- the interior of the rail is filled with a layer of soft material that is to be removed for the purpose of inserting the hammer head screws.
- corresponding undercuts of the U-legs can ensure a firm fit of the soft material layer.
- the undercuts create spot welds for the anchors.
- the undercuts can be designed in such a way that the partial sections of the U-legs that diverge toward the free end of the rail divide the welding surfaces for Form anchors lying on the rails.
- the bow-shaped anchors can have a bend directed towards the middle of the rail, which makes it easier to thread the anchors between dense reinforcement layers.
- the bend is followed by an opposite bend to form a Z profile of the armature in its side view.
- the threading between dense reinforcement layers is optimized in that, in the case of anchors arranged opposite one another, the bends are made such that at least the apex sections of the anchors are nested one inside the other.
- the rail is a fastening which is profiled in a U-shaped cross section rail 1, which is embedded in a concrete beam 2 such that the U-web 3 forming the rail back is flush with the facing web side 4 of the concrete beam.
- trapezoidal sheets 5 can be fixed on the fastening rail 1 by means of screws 6 in the usual manner.
- a hole 7 is made in the middle third of the mounting rail. This is penetrated by the screw 6, which in turn has a shaft with a self-tapping thread. Alternatively, drilling screws can also be used. If the wall of the fastening rail is thicker, set bolts can be used.
- the U-space 8 is filled with a soft material layer 9 made of foam.
- the U-legs 10 form undercuts. These are created by roof-shaped sections 10 'and 10 ⁇ of the U-legs such that the apex of both U-legs point in opposite directions.
- the soft material layer 9 can be introduced on a continuous filling system, so that there is no need for prefabricated rectangular strip elements which would have to be glued into the profile. Other suitable materials could also serve as the soft material layer. Hollow bodies and composite bodies would also be conceivable.
- Anchors 11 fixed to the U-legs 10 are used for capturing the fastening rail 1 in the concrete beam 2. In the same cross-sectional plane, two such anchors 11 are provided on the fastening rail 1.
- the anchor edge is V-shaped with the V-apex 12 lying away from the rail 1.
- the anchors 11 are formed into anchor brackets and consist of curved round steel in such a way that the V-legs 13 diverge from one another.
- Their stirrup leg ends 14 are fixed by spot welding 15 to the U-legs 10. The spot welds are located at the apex of the U-legs 10, which apex form favorable contact points.
- the anchor bracket 11 are fixed at regular intervals x to each other on the mounting rail 1.
- This distance x is preferably approximately 150 mm. Therefore, a perfect anchoring of the mounting rail without special additional measures is guaranteed even when cut to length on site.
- the V-shaped anchor brackets 11 also lead to a design that can be subjected to high loads in the longitudinal direction of the rail, due to the triangular effect.
- the distances could also be a multiple of the distance x.
- the fastening rail 1 described above can be nested inexpensively with one another for the purpose of transport, in particular when the angle between the rail back and legs is somewhat greater than 90 °.
- a fastening rail 16 of U-shaped cross section is also selected. It is composed of the U-web 17 forming the rail back and the U-legs 18. The latter also form undercuts for capturing the soft material layer 20 filling the U-space 19.
- the undercuts are in generated in the same way by roof-shaped bending of the U-legs 18 in such a way that the roof vertices are directed towards each other. This means that the outgoing from the U-web 17 sections 18 'include a smaller angle than 90 ° to the U-web 17.
- the other sections 18 ⁇ run diverging towards the free end of the rail 16. In this way, spot welds are created for the anchors 11 designed as anchor brackets.
- the corresponding contact points of the U-legs 18 are such that the armatures 11 are aligned approximately at right angles to the U-web 17.
- Each stirrup leg end 14 is held in contrast to the previous embodiment by two spot welds 15 '.
- a fastening rail 16 is selected which corresponds to the fastening rail described above.
- the anchor brackets 21 are now formed by a curved rod which runs in a corresponding wave form and has a plurality of anchors one behind the other. Regarding the same, it is round steel with a profiled surface.

- the sections 18 ⁇ of the U-legs 18 that run diverging from the free end of the fastening rail 16 now form the weld-on surfaces for the anchors 21, which then also lie in divergent planes to the rail V-shaped design of the anchor bracket 21 and its attachment to the fastening rail also allow nesting of several fastening rails during transport.
- the U-space 19 receives the soft material layer 20, which, according to the undercuts, is captively assigned to the fastening rail 16.
- the fastening rail 24 is designed as a flat strip.
- the anchors 26, which are designed to form anchor brackets, are fixed on their two narrow longitudinal sides 25. These are also V-shaped and have the interconnected V-legs 26 'with the mounting rail 24 facing away, rectilinear V-apex.
- the anchor bracket 26 are part of a rod bent in a wave shape, for which round steel is used.
- the wave crests 27 come against the narrow longitudinal sides 25 and are fixed there by spot welding 28 on the fastening rail 24 such that the anchors lying at the same height run parallel to one another.
- This configuration also has the advantage of a small anchor spacing, which is very useful for the on-site cutting to length.
- each row of anchor brackets 26 one behind the other can be connected to one another by a stiffening wire 29 running parallel to the rail 24.
- the stiffening wire 29 extends approximately over the middle length of the anchor bracket 26 and is preferably attached to the outside thereof by welding to it.
- the stiffening wires 29 also increase the load-bearing capacity of the fastening rail 24.
- the soft material layer 30 is located in the area between the anchors 26 fastened on the longitudinal edge side forming foam strip, which is held on the underside 31 of the flat strip 24 by gluing.
- the fifth version shown in FIGS. 12 and 13 largely corresponds to the embodiment according to FIGS. 10 and 11.
- the anchors 26 are fixed on the edge edge side on the underside 31 of the flat strip 24.
- the sixth embodiment shown in FIGS. 14 and 15 includes a fastening rail 32 with a U-shaped cross section, consisting of the U-web 33 and the two parallel U-legs 34.
- a soft material layer 35 is located between the latter made of foam and has a smaller width than the inner dimension between the U-legs 34.
- the soft material layer 35 is fastened to the underside of the U-web 33 by gluing.
- Anchors 26 are used in this version, which correspond to those according to FIGS. 10 and 11.
- the anchors 26 are fixed on the end face 36 of the U-leg by welding in such a way that the anchors 26 of one leg, which are arranged in rows, run parallel to the anchors of the other leg.
- a flat strip is also used for the fastening rail 37.
- the anchors 38 are formed as a continuous side plate 39 with a comb-like front edge 40.
- Each side plate 39 is at least partially with z. B. angled or dent-shaped anchor projections 41. According to the embodiment, z. B. the angled anchor projections 41 opposite side plates 39 in the outward direction.
- the anchors have a V-shaped plan.
- the end of the side plates 39 opposite the anchor projections 41 is also provided with an angled portion 42.
- the latter is opposed to the angled armature projection 41, rests against the edge on the underside of the flat strip forming the fastening rail 37 and is welded there, namely by means of spot welding.
- the side plates 39 can be provided with stiffening beads 45 which extend transversely to the longitudinal direction of the rail and extend over the corner to the bend 42.
- the wall thickness of the side plates can therefore be, for example, 1 mm thick.
- profiling 46 can also be carried out in the longitudinal direction, so that this version also offers the creation of the soft material layer by foaming, cf.
- a foam strip is used, which represents the soft material layer 44.
- the connection between the underside of the fastening rail 37 and the soft material sleeve 44 is made by gluing.
- the armatures 38 can also be spaced a short distance apart.
- the design of the side plates 39 allows them to be cut from a sheet metal strip without loss so that after the comb-like cut has been made, the side plates are present on both sides of the cutting line, the ends of which are to be bent accordingly.
- FIGS. 18 and 19, relating to the eighth embodiment, show, in contrast to the previously described embodiments, a rail designed as an anchor rail 50.
- This anchor rail 50 is C-profiled in cross section and is composed in detail of a rail back 51 and the rail side walls 52 extending at right angles therefrom, to which sections 53 bent at right angles are connected, leaving a longitudinal slot 54.
- the sections 53 run parallel to the rail back 51.
- the anchor rail 50 is embedded in a concrete structure 55 illustrated in phantom lines in such a way that the outside of the sections 53 is flush with the surface of the concrete structure.
- the interior of the anchor rail 50 is filled with a soft material layer 58, which is pulled out from the longitudinal slot side after the concrete has hardened.
- an anchor head screw 57 shown in dash-dotted lines, can be inserted through the longitudinal slot 54 and, after a 90-degree rotation shift, can be brought into the rear grip position according to FIG.
- Anchors 58 fastened to the rail side walls 52 by welding are used for capturing the anchor rail 50 in the concrete structure 55.
- Two such anchors 58, 50 are fixed to the anchor rail 50 in the same cross-sectional plane so that they protrude beyond the rail back 51.
- the edge of the anchor edge is V-shaped with the apex 59 lying away from the rail back 51.
- Round steel is used for the anchor 58, which is bent so that the V-legs 60 diverge from one another. A parallel course of the legs 60 would also be conceivable.
- the distance between two adjacent anchor brackets is selected according to the intended use, so that after an on-site cutting to length, the anchor rail 50 is properly anchored without additional measures.
- This solution also has the advantage of nesting for the purpose of transportation.
- Figures 20 and 21 relate to the ninth embodiment.
- This again relates to a fastening rail 61 which is U-shaped in cross section.
- the U-web 62 forms the back of the rail, from which the laterally angled U-legs 63 originate in a slightly divergent course.
- the interior of the fastening rail 61 is filled with a soft material layer 64 made of foam.
- bow-shaped anchors 65 are fixed to each U-leg 63 in such a way that the leg ends 66 'of the leg 66 of each anchor are attached exclusively to one longitudinal edge of the fastening rail 61.
- Two anchor brackets are each arranged in the same cross-sectional plane of the fastening rail 61.
- the armature 65 has a slight V-shape, that is to say that the armature legs 66, starting from their rounded apex 67, diverge.
- a parallel course of the armature legs 66 would also be possible.
- the bow-shaped anchors 65 have below the U-legs 63 a bend 68 directed towards the longitudinal plane of the rail EE, which is followed by an opposite bend 69, forming a Z-profile of the anchor in its side view, cf. Figure 21.
- the bends 69 which, like the bends 68, are part of the armature legs 66, run at a small distance from the longitudinal plane of the rail and parallel to one another.
- the thigh ends 66 ' are also arranged in the way of resistance spot welding on the U-legs 63.
- Two bow-shaped anchors 69, 70 are also provided in the same cross-sectional plane in such a way that the anchor leg ends of the legs 77, 78 are fixed on the outside of the U-legs 63 by resistance spot welding. Furthermore, the anchors 69, 70 are bent in a Z-shape and accordingly contain bends 71, 72 and 73, 74. The bends of two opposite anchors are designed such that at least the apex sections 75, 76 are nested one inside the other. This means that they then lie in the longitudinal center plane E-E of the fastening rail 61.
- the nesting is achieved in that the bends 71 of the armature legs 77 run towards the longitudinal center of the armature 69 and merge into the bend 72.
- the apex section 75 has a smaller radius and lies within the apex section 76 of the other anchor 70 and thereby enables nesting.
