  • Such a screw is particularly well suited to be materially anchored by adhesive as well as non-positive or positive fit by the inventive design of the composite anchor bolt in the anchoring ground.
  • the at least two, preferably three thread bands form, in the screwed-in state of the composite anchor bolt in a borehole, virtually numerous chambers between the composite anchor bolt and the borehole wall. These quasi-free spaces are filled in case of use with hardenable mass.
  • hardenable masses shrink.
  • the fact that the curable composition is in the aforementioned chambers, the shrinkage of the curable composition has a smaller negative impact on the structural behavior of the composite anchor bolt according to the invention as in the known composite rob anchorage is the case.
  • the threads located in a cross-sectional plane of the composite anchor bolt and engaging the borehole wall increase the effective area in the anchoring base, which is directly proportional to the structural behavior of the composite anchor bolt.
  • the threads located in a cross-sectional plane of the composite anchor bolt and cutting into the borehole wall influence the structural behavior of the composite anchor bolt positively.
  • each thread band has the same number of threads.
  • threads of a threaded band may have a different size outer diameter. It may be useful for other specific applications, if the threads of several tapes have a different outer diameter. It may be appropriate for certain applications, if the threads of a threaded band have the same size outer diameter.

It may be useful for certain applications if the threads of a threaded band have an equal flank angle. It may be useful for other certain purposes if the threads of several or preferably all thread bands have an equal flank angle.
  • thread tapes start evenly spaced from each other at a common circumferential line of the shank.

  • the invention also relates to a fastening arrangement in an anchoring base, preferably made of concrete, with a thread-forming composite anchor bolt according to one of claims 1 to 12, wherein the composite anchor bolt is anchored in a filled with hardenable mass borehole in Veranker ground such that an annular gap between the borehole wall and the Composite anchor bolt is completely filled with the curable composition, wherein the threaded bands of the composite anchor bolt are preferably completely or partially embedded in the anchoring ground and partially in the hardenable mass.
  • the special design of the composite anchor bolt ensures that the adhesive largely free of voids, ie without air pockets, distributed in the space between the wall of the bore and the screw.
  • the hydropneumatic pressure occurring during screwing in of the composite anchor bolt within the bore is responsible, which in particular leads to the adhesive being pressed against the setting direction in the direction of the bore opening during further screwing in, with the adhesive, in particular because of the design of the composite anchor bolt , evenly distributed, and so a very good surface adhesion between the wall and adhesive on the one hand and between screw and adhesive on the other hand is ensured.
  • the term "firm ground of anchoring" is broad. In addition to concrete, natural or artificial stone, rock, masonry or the like material is understood by a solid anchoring reason, for example, a friable masonry material, soft brick or other soft stone. Wood can also form a solid ground for anchoring. Preference is given to aerated concrete as a firm anchoring ground.

  • the frusto-conically tapered tip 18 facilitates insertion of the composite anchor bolt 10 into the bore 12 of the anchoring base 13.
  • the screw head 14 is formed in an exemplary tool engagement; This head shape is advantageous, but not mandatory.
  • the composite anchor bolt 10 has three threaded bands 20, 22, 24, each with two threads 26 a, b, 28 a, b and 30 a, b, which are arranged parallel to one another and extend helically over the length of the shank 16.
