Definitions

  • the invention relates to an anchor of the type mentioned in the preamble of claim 1.
  • Such anchors are used to fix two components to one another, for example in the case of shell masonry for fixing the two masonry shells, between which an intermediate space is formed, in which a thermal insulation layer is generally arranged.
  • the outer masonry shell hereinafter also referred to as the outer shell
  • the outer shell is subject to changes in length.
  • such anchors should be flexible to avoid bending tensile and constraining stresses, which lead to the formation of cracks, in order to permit vertical and horizontal movements parallel to the wall plane.
  • such anchors for taking up wind pressure and wind suction should not allow any movements perpendicular to the wall plane.
  • an anchor known from DE-A1 41 29 032 has anchoring members which are movable relative to one another and which are dowelled or walled in in the two masonry shells opposite one another.
  • the mobility is achieved by a specially designed connecting link that connects the anchoring links together.
  • the anchoring members are rotatable, but non-detachably attached to the anchor head.
  • Such anchors which are made in one piece due to the non-detachability, are difficult to install precisely at right angles to the masonry because of the anchor head. It is also practically impossible to subsequently adjust such anchors at right angles.
  • anchors known from CH patents 565 908 and 643 024 as well as other commercially available wire and air-layer anchors have the same problem.
  • a right-angled installation perpendicular to the wall plane is, however, an essential requirement for the functioning of a double-shell masonry in all known types of anchors.
  • anchors that are inclined upwards or downwards or bent at an angle, which block each other, would lead to constraining stresses.
  • Such anchors are either inoperative or ineffective. This creates relatively rigid connections that prevent the outer shell from moving freely.
  • the larger distance between the masonry shells chosen in recent years as a result of thicker thermal insulation layers significantly increases the problem mentioned.
  • the suitability of the anchors known today with regard to the planned installation is questionable.
  • the invention is therefore based on the object of providing an anchor which can be attached and adjusted exactly at right angles to the masonry and a flawless anchor-enclosing installation of the thermal insulation material enables.
  • the buckling load case must be reassessed due to wind pressure.
  • the solution according to the invention is based on a two-part anchor, in which the rod-shaped anchoring member detached from its connecting means is anchored and adjusted at right angles in the inner masonry shell and then, after the thermal insulation material has been put over without problems, the anchoring head - comprising a profile body and the second anchoring member, is attached - he follows.
  • a profile body 10 as a guide element has a guide slot 12 or an elongated hole, in which an anchor plate 14 as an anchoring member is slidably guided in the longitudinal direction 16A to the guide slot 12 and in part also in the transverse direction 16B .
  • the shortened anchor rod 20 has fastening means in the form of a thread 24 at its end remote from the profile body 10 .
  • the thread 24 can also be a wood thread, for example, in order to screw the anchor rod 20 into a dowel intended for such a thread and embedded in the masonry.
  • the anchor rod 20 can also be fastened to the profile body 10 using other means than with a welded-on nut, but preferably while maintaining a relative rotatability.
  • the anchor plate 14 and the profile body 10 together form the anchor head.
  • the length of the anchor rod 20 is preferably dimensioned such that it penetrates the thermal insulation layer and the anchor head 10 is adjacent to the thermal barrier coating. A cutout in the thermal insulation layer for the anchor head 10 can thus be avoided.
  • the profile body 10 is shown in longitudinal section, in which the guide slot 12 can be seen.
  • the profile body 10 is rectangular in cross section.
  • the anchor plate 14 engages in the interior 26 of the profile body 10 with a guide projection 28 serving as an engagement element for the guide slot 12 .
  • This is integrally formed on the anchor plate 14 and wider than the guide slot 12 .
  • the anchor plate 14 has incisions 30 on both sides, so that it can be inserted into the guide slot 12 in a key-like manner by turning.
  • a web 31 (FIG. 2) formed between the incisions 30 is narrower in width than the guide slot, so that the anchor plate 14 in the inserted position not only in the longitudinal direction 16A to the guide slot 12 , but also in the transverse direction 16B relative thereto , that is to say at right angles is displaceable to the axis of the anchoring members 14 , 20 . Due to the formation of the slots 30 , the anchor plate 14 is essentially immovable in the axial direction to the anchoring members 14 , 20 .
  • a clamping body 32 shown in Figures 4 and 5 is inserted from one of the two open sides in the profile body 10 before the anchor plate 14 with its Guide lug 28 is inserted through the guide slot 12 .
  • an indentation 34 is formed in the clamping body 32 by its guide projection 28 .
  • the clamping body 32 is also rotated. It is dimensioned such that it exerts a slight clamping effect in the profile body 10 , so that the anchor plate 14 is secured against falling out before the anchor is installed in the profile body 10 .
  • the clamping body 32 which is not shown in FIGS. 1 and 3 for a better overview, preferably consists of a foamed plastic, which is also known under the brand name styrofoam. As an alternative to the embodiment described above, it is also possible to foam the profile body 10 with such a plastic when the anchor plate 14 is inserted.
  • the clamping body 32 is also displaced in the profile body 10 .
  • the profile body 10 is open to its profile in the longitudinal direction.
  • a displacement in the arrow directions 16B that is to say transversely to the longitudinal extent of the guide slot 12 , is also possible since the incisions 30 in the anchor plate 14 allow play in the guide slot 12 .
  • the guide extension 28 extends the recess 34 in the clamping body 32 .
  • the two anchoring members 14 , 20 are dimensioned such that they are as small as possible on their contact surfaces form a metallic thermal bridge between the inner and outer shell.
  • the anchor plate 14 according to FIG. 3 has holes 36 as fastening means for walling in.
  • a plurality of anchors of the type described above serve to anchor the two wall parts to one another, a displacement of one wall part relative to the other not causing a change in distance, since these anchors allow a parallel displacement transverse to their axial direction. Cracks in the masonry due to bending tensile stresses are thus avoided.
  • the anchor according to the invention ensures a rigid anchoring with respect to their distance from one another. This is important, for example in the case of wind forces, in that the outer part of the wall is supported and anchored on the inside.
  • a resilient anchor as known for example from CH patent 441 679, cannot perform such a task.
  • the anchor according to the invention prevents the thermal insulation material from becoming wet, since any rainwater that penetrates and runs off on the inside of the outer shell can drip off the anchor head.
  • anchoring members described in the exemplary embodiment in the form of anchor rod 20 and anchor plate 14 , it is also possible to arrange anchoring rods or anchoring plates on both sides.
  • the guide slot 12 can also be arranged in the anchoring member itself instead of in a profile body.
  • the profile body can also have a guide slot which is open at one end or at both ends in order to enable the insertion of a guide projection which is shaped differently than in the exemplary embodiment, for example as a ball or disk.
  • the anchor described enables planned horizontal installation or installation at right angles to the wall level, so that constraining stresses are avoided and wind forces can be easily transferred to the load-bearing interior components.
  • the straight anchor rod ensures that by applying an angle gauge unimpeded to the wall plane vertical installation is possible. An inclined position is avoided by a controllable assembly.
  • the anchor plate 14 can be dispensed with in the profile body 10 .
  • the anchor according to the invention on the one hand prevents cracking in the masonry and on the other hand enables the use of relatively thin outer shells.
