Definitions

  • the invention relates to a device for the tensile connection of two components, preferably for anchoring supports to foundations, with a tie rod which is fastened in an anchor body to be concreted into a concrete body.
  • the supports of hall structures or of large machine elements with the foundations are anchoring constructions in which the tensile forces to be transmitted are transmitted to the foundation bodies by tie rods via anchor bars.
  • This anchoring construction essentially consists of two elements.
  • the first element is the anchor bar concreted deep down in the foundation body, which transfers the tensile force to be anchored by pressing between the anchor bar and the enveloping concrete of the foundation.
  • the anchor bar acts as a bending beam and must be designed to be stiff accordingly
  • the tie rod is rotated in a slot-shaped opening by the end of the door and the end of the door, so that the hammer head is caught in the anchor bar.
  • the anchor bar In this known anchoring construction, the anchor bar must be moved deep down in the foundation for two reasons. First, there must be a sufficient height of the concrete above the anchor bar to prevent the concrete from breaking out locally under the effect of the upward-acting pressure forces transmitted by the anchor bar. Second, the length of the tie rod must be chosen so large that, for the floor plan, the tolerances inevitable in construction practice between the position of the anchor bar and the position of the structural or machine element to be anchored can be compensated for by the flexibility of the tie rod .
  • Such anchors usually have installation depths of the anchor bars of 1-3 m below the upper edge of the foundation.
  • anchor bars are equipped with such pipes or not, it is difficult to secure the anchor bars in the foundation body before concreting so well that they do not change their position during the concreting of the foundation.
  • the object of the invention is to avoid the above-mentioned disadvantages of known anchoring constructions.
  • an anchoring structure is to be created which can be easily manufactured with less material. Wei should be easy and risk-free to install the construction according to the invention in the foundation. A form of construction should also be found which has a minimum of
  • the anchor body consists of a hollow body closed on the circumferential side and on the bottom, and in the upper region of the hollow body a counter body provided with an opening is firmly connected to the hollow body and in the area between the bottom and the counter body an anchor plate having a connecting thread is loosely inserted, into which the pull rod can be screwed directly through the opening of the counter body, the opening in the counter body being at least a desired tolerance dimension larger than the penetrating cross section of the pull rod and Anchor plate in the plane transverse to the axis of the tie rod is at least smaller by the desired tolerance dimension in the hollow body than the internal dimensions of the hollow body in the plane of the anchor plate, the greatest extent of the anchor plate being greater in the plane transverse to the axis of the tie rod is than the smallest inside dimension of the hollow body pers in said plane
  • an anchor body is thus arranged directly under the upper edge of the concrete body, there directly compensating for the position tolerances between the constructions to be connected, which are unavoidable in construction practice, z.3. Hall support and foundation are permitted and, through a direct transfer of force from the anchor body to the concrete body, without the interposition of rigid anchor bars, leads to significantly less material expenditure.
  • the pull rod is directly in the
  • Screwed anchor body and is therefore much shorter. Since the hammer head is also avoided at the same time, there is also a significant saving in material and costs in the tie rod. Furthermore, the inventive design lowers the weight and the transport volume and thus the transport costs considerably.
  • An expedient embodiment of the invention consists in that anchoring elements on the hollow body for direct power transmission into the concrete, preferably directly on the hollow body. consolidated anchor rods or anchor loops are arranged. The anchoring force is thus transmitted directly into the depth of the concrete body, so that the hollow body can be arranged directly on the upper edge of the concrete body without this leading to excessive stress on the concrete.
  • a further embodiment of the invention consists in that adjusting elements, preferably adjustable in height, are arranged on the upper side of the hollow body.
  • the counter body is arranged by forming an overlying space below the upper edge of the hollow body.
  • the arm body can thus be used for the direct introduction of forces transversely to the tension rod, for example for the introduction of horizontal forces between the hall support and the foundation, without any further measures on the foundation body, the body to be anchored having elements which engage in this free space. whereby there is still a direct transfer of force through the encapsulation of the free space
  • FIG. 1 shows a central section through an anchoring construction according to the invention
  • FIG. 2 shows a cross section through the anchoring construction along the line II-II in FIG. 1; 3 shows a section through the anchoring construction parallel to the axis of the drawbar, in the installed and cast state, and FIG. 4 shows an illustration according to FIG. 2 with a position secured against further rotation
  • the tie rod has a thread at its lower end. With this he is screwed into an anchor plate 2 to which an end plate 3 with a central hole is attached. As a result, the threaded part of the tie rod can be tightened against the end plate 3 with the anchor plate 2. As a result, the pull rod 1, the anchor plate 2 together with the end plate 3 form a common body for the further processes.
  • This direct screwing of the tie rod into the anchor plate 2 makes it possible to use tie rods of any length and of any configuration.
  • a simple fixing of the anchor body for the mounting of the foundation is also made possible.
  • the entire anchor body can be screwed from above onto a support placed above the foundation across the outer formwork of the foundation by means of a screw which fits into the thread 14 of the anchor plate 2.
  • the anchor plate 2 presses against the opposing body formed from two plates 4 ', 4 "above it. This has an opening 13 which is around the desired position Tolerance dimension is greater than the diameter of the pull rod 1, so that before the tension rod 1 is tightened, the body to be connected to the foundation can be arranged offset by this tolerance dimension with respect to the central position.
  • the plates 4 ', 4 "of the counter body are welded from above to the hollow body designed as a molded tube, which in the example shown has a rectangular cross section.
  • the left cross section of this molded tube is larger by the tolerance dimension than the outer contour of the anchor plate 2.
  • the anchor plate 2 can therefore be arranged offset in any direction with any tolerance up to the desired tolerance dimension, since the outer dimension of the anchor plate 2 measured across the diagonal but larger than the inside dimension of the hollow body 5 prevents the anchor plate 2 from self-fixing Twist given, that is to say that the kerplatte 2 can only be rotated to a certain extent depending on the position within the tolerance range against the hollow body 5 and then in any case the pull rod 1 can no longer be rotated. This ensures that, on the one hand, the pull rod 1 can be screwed into the anchor plate 2 from above and on the other hand also the s later adjustment of the pull rod 1 by thread and nut on the upper end of the pull rod 1 is possible.
  • the counter body 4 ', 4 "with the opening 13 has recesses 15 on the sides of the corners of the molded tube, so that the area of the cavity below the counter body 4', 4" or the anchor plate can be filled with grout from above.
  • the hollow body 5 is provided with a bottom 6 at the bottom, so that no concrete can penetrate into the interior of the anchor body when the foundation is concreted.
  • threaded sleeves 8 or the like, into which set screws 9 can be screwed can advantageously be attached to the cabbage body 5, as shown in FIG.
  • these adjusting screws 9 With the help of these adjusting screws 9, the distance between the concrete body 10 and the body 11 to be anchored can be precisely adjusted, so that this body is precisely fixed in its desired position by tightening these adjusting screws 9 or by tightening the pull rod 1 before the cavities are cast can be.
  • parts projecting downward to the lower edge of the body to be anchored can be attached, e.g. as shown in FIG. 3, a welded-on piece of a tube 12 which projects into the cavities of the hollow body 5 above the counter body 4 *, 4 ".
  • the cavities of the anchor body and the distance between the body 11 to be connected and the concrete body 10 are filled with pressure-resistant grout 16.
