Definitions

  • the invention relates to an adhesive anchor with an elongated shaft made of metal, which is provided at least in its end region outside the bore with a fastening element and has blade-like projections which occur in the end region inside the bore.
  • Threaded bolts which can also be fastened in bores by means of hardening two-component materials and are also referred to as adhesive anchors have proven themselves for those applications in which the bolt is not loaded immediately after setting and stresses at higher temperatures are not to be expected.
  • adhesive anchors To increase the load-bearing capacity, further developments of the originally only cohesive, that is to say through the adhesion of the hardened two-component mass to the bore wall, have been described, in which a tilting segment is pivotably articulated on the inside of the bore of the threaded bolt, which follows the insertion into the hole and the impact on the bottom of the hole from one that does not exceed the diameter of the threaded bolt into one on both sides radially projecting position is pivoted and then positively interlocks on an undercut surface facing the bore opening of an extension bore provided in the depth of the bore.
  • This known adhesive anchor (DE-OS 33 25 800) is therefore cohesive on the one hand by means of the hardened two-component mass and on the other hand additionally held in a form-fitting manner on the undercut surface in the bore in the manner of a tilting dowel.
  • the pivotable arrangement of the tilting segment at the end of the threaded bore inside the bore constitutes a complication and an increase in price - compared to the pure adhesive anchor ⁇ formed by only one threaded bolt - the setting process having to be carried out very carefully by reliable personnel in order to ensure that the tilting segment really pivots into the locking position.
  • the attachment thread extends over the entire length of the bolt shaft and is only by means of the blade formed without cutting ⁇ -like approaches in the inner end region interrupted, which have the task of not only intimately mixing the two-component mass which is still flowable when the threaded bolt is inserted into the associated bore, but also - by rotating the threaded bolt - also in the area of the Er ⁇ to produce a further flow of the mass flowing radially outwards, so that the expansion bore is filled properly and at the same time also a fine distribution of the additives contained in the two-component compositions in the area of the expansion bore after the hardening of the To effect mass-forming holding head.
  • the invention has for its object to set the known adhesive anchor with regard to the load capacity To improve the condition even further without the structure of the adhesive anchor becoming significantly more complex and the production costs thereby increasing.
  • the adhesive anchor should be suitable in the same way for setting in bores with an undercut as well as in normal cylindrical bores.
  • a coarser, left-handed thread of greater pitch than the fastening thread is provided, that the blade-like projections protrude from the shaft in the area of the left-hand thread, and that the shaft has a smooth, central area between the fastening thread and the coarser left-hand thread has threadless section.
  • the relatively fine and generally right-hand fastening thread is therefore only provided at the outer end in the adhesive anchor according to the invention in order to be able to carry out the desired fastening on the set anchor.
  • the thread provided at the inner end of the bore is deliberately coarse and with a larger pitch and - what is particularly important - has a left-handed thread sense.
  • the coarse left-hand thread can be a common thread, for example with a tapered cross-section of the threads.
  • thread can also be designed as a so-called trapezoidal thread, in which the threads therefore have a trapezoidal cross-section.
  • the surface of the smooth central area lying between the fastening thread and the coarser left-handed thread can also have a surface preparation that at least reduces the adhesion of setting or hardening anchoring compound.
  • the smooth threadless section has a diameter which is smaller than the core diameter of the fastening thread and / or the left-hand thread.
  • the smooth unthreaded section then acts like the expansion shaft of a highly stressable expansion screw.
  • the anchoring of the adhesive anchor in the anchoring compound which in turn is anchored in the hardened or set state in the associated bore, therefore takes place essentially only in the area inside the bore provided with the left-hand thread.
  • Adhesive anchors introduced tensile forces are therefore not hindered.
  • Blade-like approaches are preferably provided on opposite sides of the shaft, although an arrangement distributed regularly or irregularly on the shaft circumference is also conceivable.
  • the scoop-like approaches preferably come from the threads of the left-hand thread.
  • the end face of the adhesive anchor inside the bore can run at an angle to the longitudinal central axis of the shaft be arranged so that it forms an inclined surface which breaks, for example when the shaft of the adhesive anchor is inserted into an associated bore, which, in a flowable form, receives the two components of the anchoring compound separately from one another and flows into the bore before the adhesive anchor is inserted and supports the mixing action of the rotating shaft.
  • FIG. 1 shows a side view of an adhesive anchor according to the invention placed in a fastening bore in a subsurface, the subsurface being shown in section with the cutting plane laid through the longitudinal central axis of the fastening borehole;
  • FIG. 2 shows a side view of the adhesive anchor shown in FIG. 1;
  • FIG 3 shows a side view of a modified exemplary embodiment of the adhesive anchor according to the invention.
  • the adhesive anchor according to the invention shown in FIGS. 1 and 2, designated in its entirety by 10, is inserted in a fastening bore 12 in a base 14 - for example a concrete floor - and is insoluble by an anchoring compound 12 which has hardened after mixing two components Darge ⁇ anchored in the bore 12.
  • the mounting hole in the case shown is a simple hole made with a stone drill,
  • an extension bore (not shown) made with a special undercut tool, the diameter of which is larger than the diameter of the bore 12 can be provided, as a result of which a fastening bore expanded in the region facing away from the mouth with an undercut surface facing the mouth of the bore would arise.
  • the adhesive anchor 10 is essentially formed by an elongated shaft made of metal, preferably a steel having a sufficient load-bearing capacity, which is subdivided into three successive different areas 16, 18 and 20.
  • the end region 16 protruding from the bore after the armature has been set in the bore 12 has a fastening thread 22 onto which, for example, a fastening nut can be screwed.
  • the inner face 28 of the adhesive anchor hole is an inclined surface inclined at an angle of approximately 45 'to the longitudinal central axis of the adhesive anchor.
  • the anchoring compound 16 used to fix the adhesive anchor 10 in the substrate 14 consists, as in the case of conventional adhesive anchors, on the one hand of a hardenable synthetic resin compound which is mixed with additives and which is flowable in the uncured state, and on the other hand of a small amount of one - in the non-hardened state Condition also flowable - hardeners, which either contain separately from each other in a breakable two-chamber cartridge or are introduced into the bore in a suitable quantity ratio from separate stocks before setting the adhesive anchor.
  • an anchoring compound filled in a single-chamber cartridge and hardening due to the atmospheric oxygen coming in after the cartridge has broken In order to break the cartridge and then mix the components of the anchoring compound, the adhesive anchor is expediently clamped into a hammer drill with its rear end of the bore, ie, the fastening thread 22, and then inserted into the fastening bore while the drill hammer motor is running.
  • the inclined surface 28 running against the two-chamber cartridge breaks the cartridge, so that the synthetic resin composition and the hardener emerge and are mixed by the rotating end section provided with a left-hand thread, the lugs 26 particularly promoting this mixing.
  • the thread acts like a screw pump, ie the synthetic resin hardener mass pushes towards the inside of the bore, so that the space between the adhesive anchor 10 and the wall of the bore 12 is closed At least over the length of the end region 20, which forms the actual anchoring area, is completely filled with the anchoring compound, any residual water contained in the hole being displaced, for example by a previous wet drilling process.
  • the exemplary embodiment of the adhesive anchor 10 shown in FIG. 3 differs from the adhesive anchor shown in FIGS. 1 and 2 in that the threads of the thread 24 have a trapezoidal cross section, i.e. that the thread 24 is a so-called trapezoidal thread.
  • the smooth, threadless section 18 of the adhesive anchor shaft has a smaller diameter than the core diameter of the fastening thread 22 and the left-hand thread 24.
  • the section 18 thus absorbs vibrating or swelling stresses such as the expansion shaft of one Expansion screw. Accordingly, the change in diameter in the transition from sections 18 to sections 16 and 20 should also not be abrupt, but should take place in the manner illustrated in FIG. 3 with a transition section 30 rounded in cross section.
  • modifications and further developments of the adhesive anchor described are possible which relate, for example, to the formation in the end face 28 as an inclined face.
  • the inclined surface 28 could be replaced by two opposing surfaces forming a chisel-like cutting edge, as in the known adhesive anchor.
  • the special arrangement of the blade-like attachments on opposite sides and their arrangement only in the first thread turns can be changed, for example, by forming such attachments on the thread turns at angular intervals of 120 ° in each case.
