    (54) METAL FASTENING ELEMENT
    one
    The invention relates to the construction, in particular to metaplic fasteners used to fasten various objects and equipment to panels, slabs, hollow columns and other thin-walled building structures.
    A fastening element is inserted into the through-hole of the plate and consisting of a screw, which covers its sleeve with an internal thread at the end of G1.
    However, a large force is required to crimp the end portion of such a fastener, while the strength and reliability of the fastening is insufficient.
    The closest to the proposed technical essence and the achieved result is a metal fastener, including a screw, covering its cylindrical Etulka, consisting of an end portion with internal thread, an upper non-rifled portion and an intermediate non-rifled portion, cut by longitudinal slits into strips, each which is
    from the expansion and mounting areas C2.
    However, the reliability and durability of fastening with such a fastener is insufficient. This is due to the loose fit of the fastening sections to the inner surface of the building structure, as well as the possibility of twisting and bending of the extension sections when tightening the screw.
    The aim of the invention is to increase the reliability and strength of the fastener.
    15
    This goal is achieved by the fact that in a metal fastener, a screw is turned on, covering its cylindrical sleeve consisting of an end portion with an internal thread,
    20 of the upper non-tapped portion and the intermediate non-tapped portion cut by longitudinal slits into strips, each of which consists of a spacer and anchoring portions,
    25 spacer sections of the strips are arcuate in cross-section, and fasteners are flat.
    At the same time, for fixing the position 30 of the sleeve, its upper section is provided with support bends with Stop. ledges
    Spacer strips in places adjacent to the end part of the sleeve can be made with a weakened section, with protrusions in contact before screwing the screw with its surface 4 | Yu.
    The sleeve may be made of sheet scan with a thickened end portion.
    FIG. 1 shows a fastener, a general view; in fig. 2 - fastener secured in the hole of the plate.
    The fastening element 1 consists of a sleeve with an internal thread 2, a thickened end part 3, a screw 4, an end part entering into the sleeve and a thread-end interacting with the thread. The sleeve has an upper non-tapping portion 5 and an intermediate non-tapping part cut by longitudinal slits into strips, each of which consists of a flat mounting 6 and a spacer 7 arcuate in cross section sections. The upper portion, the sleeves are provided with support bends 8 having locking protrusions 9. In places adjacent to the end part 3 of the bushings, the spacer portions 7 of the strips are made with a weakened section formed by notches 10 and transverse slots 11, the inner side has spacer portions 12, prevent them from bending inward when screwing in the screw. The end portion of the sleeve has a double thickness of the SHEET scan, formed by bending its edges. In the manufacture of the sleeve fastener from the sheet stamped scan and roll it into a cylindrical shape under the screw, from the inner side of the end portion cut or roll the thread
