Definitions
- the invention relates to a sleeve anchor made of steel, if necessary also from a high-strength reinforced Special plastic with material data, in particular strength data, that at least correspond to those of steel.
- a Sleeve anchor essentially consists of a shaft, usually a solid round bar with bends or other undercut configurations at the foot end, and one at an opposite head end of the shaft on this fixed sleeve with internal thread for screwing in if necessary a sling when lifting and moving Molded concrete parts, such as support elements, wall elements or Ceiling elements, especially for building construction.
- Rope loops are usually used as the sling with pressed-on external thread bolt or, especially for higher ones Loads, massive mostly eyelets made of steel, the are articulated with a threaded bolt.
- a sling which is designed for a limit load of, for example, one ton, is screwed into a sleeve anchor, which corresponds to the load for a limit load of 15 t
- Cross-manufacturer a system developed in which everyone A specific thread specification is assigned to the load group. This are, at least in the area of the Federal Republic of Germany, the Metric M thread according to DIN 13 part 1 and the Rd round thread similar to DIN 408.
- the ten to twelve load groups are distributed to specific thread diameters in the range 10mm - 60 mm.
- the security system shown above has in With regard to safety-related aspects over many years well proven and reliable. However, it shows the serious Disadvantage of being significantly uneconomical and expensive. So must not only the manufacturer of the molded concrete parts to cover the Load group range from ten to twelve different sleeve anchor types in large stock for the production, but also the Site managers on site for each of the load groups several Slings, i.e. large numbers of slings, stockpile. This causes considerable costs on both sides both from the material side and from the logistics of Parts availability.
- a sleeve anchor of this type trained safety thread is with absolute and one hundred percent security even with one today on construction sites in the European Union and especially in the area of the Federal Republic of Germany only screw-in lifting gear with right-hand thread to use. So it can only match with a higher one dimensioned load-bearing slings are used, the as a system-compatible safety thread Left-hand thread carries.
- the invention can be realized in that instead of a standard left hand thread either a then in this system "unusual" right-hand thread or from the start Thread is designed and used as a safety thread that in terms of its other thread characteristics, such as in particular flank profile, slope height or flank angle, in intended geographical area of application singularly, the means is completely unusual.
- the invention achieved that one with respect to the limit resilience to each other coordinated security system accidentally or improperly is used with undersized lifting gear.
- the Configuration of the safety thread allows screwing in if applicable, available or available in the scope Usual slings even in the event of deliberate abuse not even to begin with.
- the invention is based on a Exemplary embodiment explained in connection with the drawing.
- FIG. 1 shows the head section of a sleeve anchor 1 shown, the one cast in the concrete part or to be cast in shaft 2 and one on this fixed by pressing sleeve 3.
- the anchor sleeve 3 is with provided with an internal thread 4, in which a screw bolt complementary external thread can be screwed in, here in the Figure not shown, in the usual way with a sling is connectable.
- the internal thread 4 is like the external thread of the Bolting the lifting gear against the usual practice and the usual design of the threaded bolts more common Lifting gear as left-hand thread, that means with the usual Right-hand thread with opposite thread pitch.
