Definitions

  • the invention relates to an anchor for use in a Anchor rail for construction technology, especially C or Has a U-shaped cross section.
  • Anchor channels with bolts of this type are known (EP-A 154 157). They are manufactured by the meter. Here the anchors are firm and captive with the back of the Anchor rail connected and arranged at predetermined intervals. Anchor channels of this type are used on the construction site cut to exact size, attached to the concrete formwork and then, for example, concreted into a ceiling. With conventional anchor channels, the distance between adjacent ones is Anchoring, for example, 250 mm. For safety reasons and to prevent that from cutting off created end of the anchor channel under load bends out of the concrete, the protrusion of the anchor channel a certain one over the last anchor before the interface Do not exceed dimension, for example 25 mm. Because the individual, required length dimensions of the anchor channel are of different sizes, arise when cutting the The anchor channel is a piece of waste of different dimensions Length if the overhang of the anchor channel over the last anchor in front of the interface larger than permitted is.
  • This subsequently created on the end section of the anchor rail through any interface, attached anchors should be firmly connected as standard with the rail Anchor all occurring stresses, in particular Can absorb tensile and bending forces.
  • the clamp can be combined with the anchor the anchor rail at least approximately its inner profile, thus correspond to the anchor channel cavity. Furthermore, the clamping claw can be tapered, so that they are easily in the end of the anchor rail can be taken.
  • the clamping part expediently has a receiving part on the bolt receiving at mounted anchor lies outside the end section and with that of the bolt by screwing in or other suitable Way can be firmly connected. Thereby are recording part and clamp claw preferably formed in one piece.
  • the one-piece Clamping part designed like a screw clamp is such that the clamping claw in the cavity of the end portion insert the anchor rail and via a connecting part is rigidly connected to the receiving part.
  • a Such a clamping part can be inserted into the end section the anchor rail by screwing the anchor on Bottom of the anchor rail so tight that the anchor together with the clamping part that occurs after concreting Can easily accommodate stresses and this prevents the larger anchor rail protrusion from bending open.
  • the invention thus makes it possible to anchor the respective anchor rail local dimensions with regard to a possible Adapt the protrusion exactly, without any manufacturing disadvantages to fear for the built-in anchor rail are.
  • An anchor channel can therefore be used without consideration on the size of the protrusion at any point be cut to length without, as before, cut off Parts of the anchor channel accumulate as waste.
  • sawing costs when cutting the anchor channel reduced to size, since each with only a single saw cut the anchor channel without cutting to size from the prefabricated longer anchor channel are separated can.
  • an end portion 4 is one in cross section shown about C-shaped anchor rail 2, the bottom 2 'merges into leg 2 "bent approximately perpendicular to it. These legs 2 "are at the ends by 90 ° in Bent towards each other that an insertion slot 12 is formed becomes.
  • An anchor 1 is attached to the anchor rail 2, which consists of a bolt 5 and a clamping part 3.
  • the bolt 5 or 5a of the armature 1 is easier Bolt executed, while the bolt 5 'in the embodiment 3 and 4 for larger anchor channels or a particularly high one for higher loads Has firmness.
  • the end section 4 of the anchor rail 2 is in all versions, for example by sawing off the Anchor channel created to exact measure.
  • the armature 1 As a result of the invention Formation of the armature 1, after which the bolt 5, 5 ', 5a is assigned a clamping part 3, the armature 1 by means of the clamping part 3 after tailoring the Anchor rail placed on its end section 4 and with be firmly attached to him.
  • the armature 1 thus has a clamping part 3 for placing and connecting to the end portion of the Anchor rail 2 to this end section and thus the over protruding the last of the existing anchors Support the length of the anchor channel, for which the Anchor 1 is subsequently attached to the anchor rail. In this way, anchor channels can be opened without waste cut the exact length regardless of the size of the remaining protrusion over the last rail anchor.
  • Anchor with its clamping part is a safe support of the protruding piece of anchor rail after concreting guaranteed. Since the anchor 1 according to the invention with its Clamping part 3 at any desired point on the protrusion can be retrofitted to the anchor channel by a standard 6 m long anchor rail, for example any anchor channel length can be cut off without waste of material.
  • the bolt 5 and the clamping part 3 can be separate parts be, the bolt 5, 5 a screwed into the clamping part 3 is, as is the case with the embodiments according to FIGS. 1, 2, 5, 6 and 7, 8 is provided. 3 and 4 show can the bolt 5 'but also by upsetting, pressing or in another way by appropriate material forming be rigid and permanently connected to the clamping part 3.
  • the clamping part 3 For clamping in the free cavity of the end section 4 the anchor rail 2, the clamping part 3 has a clamping claw 6 by means of which the armature 1 is fixed to the end section 4 the anchor rail 2 is to be connected. Accordingly, the Clamping claw 6 at least approximately to the inner cross section the anchor channel cavity adjusted to make it as simple as possible and to position it securely in this cavity. At 1 to 4 has the clamping claw 6 one decreasing towards the interior of the anchor channel cavity Cross section, the clamping claw preferably wedge-shaped is rejuvenated.
  • a receiving part 7 is provided in the built-in State of the anchor 1 outside the end portion 4 of the Anchor rail lies and is intended to receive the bolt 5 and keep.
  • Clamping claws 6 and 6 are useful Receiving part 7 made in one piece, its walls over the entire length of the clamping part 3 with the same wedge angle are rejuvenated.
  • the bolt 5 or 5a is easier Bolt formed as a separate part is screwed to the clamping part 3.
  • the bolt 5a is in a threaded bore 9 "of the receiving part 7a screwable.
  • the clamping claw 6 At least in its cross section approximately the C- or U-shaped hollow cross section of the Adjusted anchor rail, its length at least twice is greater than the axial extent of the associated Receiving part 7, as shown in FIGS. 1 and 2 Embodiment can be seen.
  • the clamping part 3 consisting of clamping claw 6 and receiving part 7 a closed cross section, so that undesirable deformations when struck be avoided.
  • the arrangement is such that the clamping claw 6 approximately according to the profile of the anchor rail 2 Is U-shaped with side legs 6 ", which after the clamping claw 6 is hammered into the rail 2, that is to say in the clamping position, on bent legs 13 support the side leg 2 "of the anchor rail 2.
  • Anchor 1 shown, in which the clamping part 3 with a clamp claw 6a and a receiving part 7a according to Art a screw clamp is designed, these two parts by one outside the end section 4 of the anchor rail 2 located part 10 are rigidly connected to each other, so that they form a one-piece clamping part 3, the receiving part 7a for the bolt 5a on the outside of the bolt 2 'of the anchor rail 2 is.
  • the clamping claw 6a has a clamping surface 6'a which runs parallel to the bottom 2 'of the anchor rail 2 and by means of of the bolt 5a against the anchor rail base 2 ' can be braced.
  • the clamping claw 6a, the receiving part 7a and the part 10 connecting these two parts are in one piece formed, wherein between the claw 6a and the receiving part 7a has a slot 11 so that the clamping part 3 together with the bolt 5a on the bottom 2 'of the end section 4 the anchor rail can be plugged on.
  • Advantageous are clamping claw 6a, receiving part 7a and connecting part 10 designed to be a single piece of high strength form that has a cube or cuboid shape.
  • clamping claw 6a dimensioned so that they the clear width of the anchor channel cavity almost filled, but still a Slightly push the clamping part 3 onto the anchor rail is guaranteed.
  • This version has the advantage that a secure and immovable position after inserting the Clamping claw 6a guaranteed even then in the anchor rail is when significant lateral forces on the anchor 1 are effective.
