Definitions

  • Anchor rails are typically arranged flush, sunk into a floor or a wall made of concrete and are used to fasten objects, for example machines, with the help of, for example, hammerhead screws. “Flush recessed” means that the anchor rail is embedded in the concrete and one side of the anchor rail is flush with a surface of, for example, the concrete.
  • the anchor rails are cast with concrete on three sides.
  • the anchor rails typically have a C-profile rail, that is, a square tube profile or a rectangular tube profile with a continuous longitudinal slot in a transverse center of a side also referred to here as the “top”.
  • the European patent application EP 3 438 361 A1 discloses an anchor rail with a C-profile rail, from which bolt-shaped anchors with foot washers protrude in a longitudinal center plane of the C-profile rail from an underside opposite a slot in the C-profile rail for anchoring in concrete, which are concreted into the concrete when the anchor rail is cast in concrete and anchor the anchor rail in the concrete perpendicular to a surface of the concrete to prevent it from being torn out of the concrete.
  • the anchor rail is arranged parallel to and close to the edge of the concrete body.
  • anchor rails that are arranged close to an edge of a concrete body for structural reasons usually have to be “re-anchored”.
  • the well-known method provides for anchoring back against a transverse force transverse to the C-profile rail and parallel to the surface of the concrete Anchor rail has rod-shaped anchors, which protrude perpendicular to the central plane in which the bolt-shaped anchors are located, from the underside opposite the slot in the C-profile rail.
  • the rod-shaped anchors When setting in concrete, the rod-shaped anchors are embedded in concrete parallel to the surface of the concrete and sunk below the surface of the concrete by a height of the C-profile rail.
  • the rod-shaped anchors absorb a transverse force acting on the anchor rail and prevent the anchor rail from breaking out of the concrete body in the direction of the edge of the concrete body.
  • the disadvantage of the back anchoring of the prior art is that this back anchoring does not have to be subsequently attached to a concrete body, but must inevitably be cast in during the production of the concrete body.
  • the object of the invention is to propose a more flexible anchoring, which on the one hand offers the possibility of subsequently anchoring an anchor rail to or in concrete and, on the other hand, enables a planned anchoring of an anchor rail while the concrete is being poured.
  • the anchor rail of the fastening arrangement according to the invention has a C-profile rail with a slot in a first side of the C-profile rail, which is intended to be embedded in concrete, such that the first side of the C-profile rail is in particular flush with a surface of the concrete and the C -Profile rail is also embedded in the concrete.
  • the slot is in particular a continuous slot in a longitudinal direction of the C-profile rail, in particular in a transverse center of the C-profile rail or its first side.
  • One or more anchoring elements protrude from a second side opposite the first side, which anchor the concrete-encased C-profile rail in the concrete.
  • the anchor rail has at least one surface anchor for re-anchoring the C-profile rail, which rests on the first side of the C-profile rail and protrudes from a third side of the C-profile rail, that is, relative to a third side adjacent to the first side.
  • the part of the surface anchor that protrudes from the C-profile rail projects in particular at a right angle from the C-profile rail and is designed as a tab.
  • the tab is in particular a flat steel or a cut or punched sheet steel.
  • the tab has a width in particular of less than 60 mm, preferably between 30 mm and 50 mm. “Width” means the extent of the tab in the longitudinal direction of the C-profile rail.
  • a length of the tab is many times greater than the width of the tab.
  • the length of the tab preferably corresponds to at least three times and in particular at least five times the width of the tab. However, depending on the structural environment and the intended use of the surface anchor, the length can be five to ten or twenty times the width. Even longer tabs are also possible.
  • several surface anchors are arranged on the anchor rail, in particular equidistant from one another, whereby constant anchoring is achieved over the entire length of the anchor rail.
  • the surface anchor does not have to be directly connected to the third side or arranged directly on it, but rather only protrudes or protrudes over this surface.
  • the support can be done directly or indirectly, for example via an intermediate piece for height compensation.
  • the surface anchor can be connected to the C-profile rail on the first side.
  • the surface anchor is in operative connection with the slot of the C-profile rail and can additionally be connected to the first side of the C-profile rail.
  • the surface anchor does not necessarily have to engage with the slot.
  • the surface anchor could, for example, be placed on the first side of the C-profile rail so as to be flush with the surface and, in particular, only partially cover the slot, and be fastened there, in particular by welding, to the C-profile rail.
  • the surface anchor can be designed at least in sections as a type of sheet metal strip with an opening, the dimension of the opening essentially corresponding to the extent of the slot in the C-profile rail.
  • the sheet metal strip with the breakthrough is welded onto the first side of the C-profile rail or otherwise attached to it, for example by riveting, so that the breakthrough only partially covers the slot.
  • a width of the opening corresponds to the transverse width of the slot in the C-profile rail
  • the surface anchor or more precisely the tab of the surface anchor, is arranged on the C-profile rail in such a way that when the C-profile rail is concreted in in the intended manner, it protrudes to the side from the C-profile rail and rests on the surface of the concrete or is flush with the surface of the Concrete completes.
  • the surface anchor or anchors have an anchoring means at a distance from the C-profile rail, in particular at one end of the tab.
  • the anchoring means is generally a possibility or device for attaching the surface anchor to the concrete.
  • it can be a hole in the tab through which the Surface anchor can be fixed to the concrete by means of a fastener, for example a bolt anchor, a concrete screw, an anchor rod chemically fastened in the concrete or the like.
  • the surface anchor can also be anchored so deeply in a building part made of concrete, in particular cast into the building part, that it is in particular flush with the surface of the concrete, or the building part.
  • the surface anchor is therefore particularly flush with the surface.
  • the surface anchor is at least partially cohesively connected to the concrete and the anchoring means are in particular also at least partially cast into the concrete.
  • the anchoring means are in particular holes, bolts, wave anchors or the like.
  • the advantage of the planned type of anchoring is that the surface of the concrete is essentially completely usable and is not blocked by the surface anchor. During subsequent anchoring, the surface anchor rests on the C-profile rail, resulting in a potentially disruptive bump on the otherwise flat surface of the concrete.
  • the invention has the advantage that a C-profile rail of an anchor rail that has already been set in concrete can be subsequently secured against transverse force loading, i.e. anchored back.
  • This can be advantageous or even necessary if the C-profile rail is arranged close to the edge in concrete if there is a risk of the concrete breaking out to the side of the C-profile rail at the edge of the concrete or has already occurred.
  • the planned anchoring of the C-profile rail also prevents concrete from breaking out, whereby, as already mentioned, the entire surface of the concrete can be used.
  • the surface anchor protrudes laterally from the C-profile rail or from its third side on a plane flush with the first side of the C-profile rail that has the slot, or is flush with the first side of the C-profile rail enforce level.
  • the third side is the side of the C-profile rail adjacent to the first side having the slot.
  • the surface anchor rests on the surface of the concrete when the C-profile rail is concreted in as intended.
  • the surface anchor penetrates into the concrete from the side of the C-profile rail.
  • the second case is intended for initially attaching the surface anchor to the C-profile rail, so that the surface anchor is also concreted in when the C-profile rail is set in concrete and does not have to be subsequently sunk into the concrete.
  • this version has the advantage that the surface anchor does not rest on the concrete over its full length, but is partially or completely in the concrete.
  • Attaching the surface anchor to the C-profile rail is possible, for example, by hanging the surface anchor in the slot of the C-profile rail.
  • the suspension only needs to be tensile-resistant in the direction in which the surface anchor protrudes from the C-profile rail, i.e. it must be able to transmit a transverse force from the C-profile rail as a tensile force to the surface anchor.
  • Hanging the surface anchor in the slot of the C-profile rail is a simple, quick and inexpensive way to connect the surface anchor to the C-profile rail.
  • the surface anchor can have a single hook which, for connecting to the C-profile rail, surrounds a first slot edge of the slot in the C-profile rail, so that it transmits a transverse force of the C-profile rail as a tensile force to the surface anchor.
  • the surface anchor can also have a double hook which surrounds the first slot edge of the slot in the C-profile rail and engages under an opposite second slot edge of the slot in the C-profile rail when the double hook or the surface anchor is connected to the C-profile rail, so that the double hook cannot be easily lifted out of the C-profile rail.
  • another embodiment of the invention provides a fastener attached to or in the C-profile rail, which has a shaft that protrudes from the slot in the first side of the C-profile rail.
  • the fastener can be, for example, a hammerhead screw or a sliding block with a screwed-in threaded bolt.
  • the surface anchor is attached to the shaft of the fastener protruding from the slot in the C-profile rail.
  • the surface anchor has a surface structuring, in particular a toothing, on a side facing away from the first side.
  • a fastener for example a fastener as described in the previous paragraph, can be secured against displacement along the slot of the C-profile rail by means of shape and/or friction.
  • One embodiment of the invention provides that the surface anchor connects the C-profile rail with a second C-profile rail, which is arranged at a distance from the one C-profile rail.
  • the surface anchor transfers the load from one C-profile rail to the other C-profile rail, which is arranged at a distance.
  • the surface anchor has a pseudoplastically stretched shape memory alloy or consists of a pseudoplastically stretched shape memory alloy.
  • Shape memory alloys are metal alloys that change their shape through a phase transformation of their crystal structures, especially between martensite and austenite. The phase transformation and shape change occurs when a transformation temperature is reached or exceeded. Beforehand, the shape memory alloy must be pseudoplastically deformed, which typically, but not necessarily, occurs through mechanical deformation, which can then be completely or partially reversed by heating to or above the transformation temperature. Shape memory alloys with a two-way effect are also known, which deform at high temperature and completely or partially reshape at low temperature. In this embodiment of the invention, a tensile stress can be generated in the surface anchor after the surface anchor has been fixed to or in the concrete by heating the surface anchor to or above the transformation temperature of the shape memory alloy, that is, the surface anchor is prestressed.
  • One embodiment of the invention provides an elastically and/or plastically deformable strip on the outside of a fourth side of the C-profile rail adjacent to the first side and opposite the third side.
  • the first side has the slot and the surface anchor protrudes from the adjacent third side.
  • the deformable strip is therefore located on the outside of the C-profile rail opposite the side from which the surface anchor protrudes.
  • the deformable strip preferably occupies an entire area of the fourth side of the C-profile rail.
  • the deformable strip enables a slight displacement of the C-profile rail in the concrete in a direction transverse to the C-profile rail opposite to the direction in which the surface anchor protrudes from the C-profile rail.
  • the above explanations of the anchor rail are referred to.
  • the C-profile rail of the anchor rail is anchored recessed in a structural part made of concrete in such a way that its first side, which has the slot, is flush with a surface of the part of the building.
  • the surface anchor is connected to the C-profile rail on the first side and protrudes from the C-profile rail on the third side adjacent to the first side.
  • the surface anchor, or more precisely the tab rests on the surface of the building part and is fixed to the building part at a distance from the C-profile rail or penetrates the side of the C-profile rail into the building part.
  • the C-profile rail is arranged close to an edge of the structural part, i.e. close to the edge, and in particular parallel to the edge of the structural part. “Near” here means that the distance of the C-profile rail from the edge corresponds to a maximum of twice the length of the C-profile rail, in particular that the distance is less than the length of the profile rail.
  • the surface anchor or more precisely the tab of the surface anchor, extends away from the edge of the structural part at a particularly right angle to the C-rail. The tab of the surface anchor is therefore facing away from the edge.
  • the tab is fixed, in particular at a tab end that faces away from the C-profile rail, on the surface of the building part or in the building part itself, which ensures a stable anchoring of the anchor rail. Thanks to the fastening arrangement according to the invention, anchor rails can therefore be safely cast into a component near the edge without the risk of them breaking out of the structural part under load.
  • the C-profile rail can also be anchored so deeply recessed in the concrete structural part, in particular cast into the structural part, that the surface anchor is flush with the surface of the structural part.
  • anchor rail 1 has a C-profile rail 2, which has a rectangular hollow profile with a longitudinally continuous slot 3 in a first side 4, which can also be referred to as the top of the C-profile rail 2.
  • the anchor rail 1 or its C-profile rail 2 is intended to be embedded in concrete in a structural part 5 such as a concrete floor in such a way that, as in Figure 1 can be seen, the first side 4 of the C-profile rail 2, which has the slot 3, is flush with a surface of the structural part 5 and the C-profile rail 2 is otherwise sunk into the structural part 5. Only individual edges of the building part 5 are drawn and it is drawn transparently so that the anchor rail 1 is visible.
  • Anchoring elements 7 protrude from a second side 6 opposite the first side 4, which can also be referred to as the underside of the C-profile rail 2, and are fastened, for example welded, to the second side 6 of the C-profile rail 2.
  • the anchoring elements 7 are bolts with flange-shaped feet 8 at their ends remote from the C-profile rail 2.
  • the anchoring elements 7 are embedded in the concrete of the structural part 5 and hold the C-profile rail 2 against being torn out of the structural part 5 perpendicular to its surface.
  • the anchoring elements 7 are arranged in a longitudinal center plane of the C-profile rail 2.
  • the anchoring elements 7 can, for example, also protrude from the second side 6 of the C-profile rail 2 in a V-shape, viewed in the longitudinal direction of the C-profile rail 2, and protrude into the structural part 5 (not shown).
  • a strip-shaped surface anchor 9 is suspended in the exemplary embodiment, which rests on the first side 4 of the C-profile rail 2 and on or from a third side 10 of the C-profile rail 2 adjacent to the first side 4 Tab sticks out.
  • the surface anchor 9 rests on the surface of the structural part 5.
  • the surface anchor 9 has a single hook 11, which surrounds a first slot edge 12 of the slot 3 of the C-profile rail 2 and in this way connects the surface anchor 9 to the C-profile rail 2 in a tensile manner.
  • tensile strength is meant that the single hook 11 of the surface anchor 9 suspended in the slot 3 of the C-profile rail 2 transmits a transverse force acting transversely to the C-profile rail 2 as a tensile force acting in a longitudinal direction of the surface anchor 9 to the surface anchor 9.
  • the surface anchor 9 has a hole at one end of the tab, which is generally referred to here as anchoring means 13 of the surface anchor 9.
  • anchoring means 13 of the surface anchor 9 Through the hole in the tab forming the anchoring means 13, the surface anchor 9 can be fixed to the structural part 5 at a distance from the C-profile rail 2 and thus serves to anchor the C-profile rail 2 back.
  • a screw can be inserted through the anchoring means 13 designed as a hole of the surface anchor 9 are screwed into an expansion dowel, which is spread and anchored in the structural part 5 (not shown).
  • the surface anchor 9 can also be fixed, for example, by gluing it to the surface of the structural part 5.
  • the adhesive forms the anchoring means, which connects the surface anchor 9 to the structural part 5 at a distance from the C-profile rail 2 even when the adhesive is applied to the surface anchor 9 up to the C-profile rail 2.
  • the C-profile rail 2 has a deformable strip 15 on the outside, which covers the fourth side 14 of the C-profile rail 2 completely or almost completely covered.
  • the strip 15 consists of an elastic, solid foam.
  • the fourth side 14 of the C-profile rail 2 borders on its first side 4 with the slot 3 and on the opposite second side 6, from which the anchoring elements 7 protrude.
  • the fourth side 14 of the C-profile rail 2 is located opposite the third side 10, on or from which the surface anchor 9 protrudes.
  • the deformable strip 15 allows a slight movement of the C-profile rail 2 in the structural part 5 transversely to the C-profile rail 2, parallel to the surface of the structural part 5 and away from the surface anchor 9, when the C-profile rail 2 is transverse to itself, that is is loaded longitudinally to the surface anchor 9 and away from it. This prevents the concrete of the structural part 5 from breaking out prematurely when the C-profile rail 2 is subjected to such transverse stress.
  • the C-profile rail 2 of the anchor rail 1 preferably has a plurality of surface anchors 9, which are suspended transversely to the C-profile rail 2, parallel to one another and at distances from one another in the longitudinal direction of the C-profile rail 2 in the slot 3 of the C-profile rail 2 and on the structural part 5 are set.
  • the surface anchors 9 secure the C-profile rail 2 against a transverse force and prevent the concrete from breaking out, especially when the C-profile rail 2 is arranged close to the edge in the building part 5.
  • the surface anchors 9 stand on an edge 16 of the building part 5 that is close to the C-profile rail 2 opposite side of the C-profile rail 2.
  • the surface anchor 9 can also be angled so that it penetrates into the concrete of the structural part 5 next to the C-profile rail 2 and secures the C-profile rail 2 on the structural part 5 against a transverse force.
