    • 专利摘要:
    Fasteners, which are used for fastening high loads, are braced in the hole (1) by means of a spreading body (8) which is moved in a spreading sleeve (9). If the fastener is subject to high instantaneous stresses, for example as the result of earthquakes, there is the risk that the fastener may break out of the hole (1). In order to ensure that the fastener continues to maintain its retaining function, even after the occurrence of high excess stresses, the spreading sleeve (9) is operated by means of a force store, which is preferably designed as a screw spring (10). The tensile force exerted by the fastened object on the fastener is transmitted via this force store to the spreading body (8). In the event of shock stresses, the force store acts as an elastic spring element which absorbs hard shocks elastically. The fastener is thus particularly suitable for use in earthquake-hazard regions or in areas where enhanced safety requirements apply. <IMAGE>

    专利说明:

    The invention relates to machine building, in particular to fastener elements for mounting in holes of an irpticial (masonry) masonry.
    The purpose of the invention is to develop the reliability of a compound exposed to 5 gift loads.
    The drawing shows a fastening element placed in a concrete base and holding a fixed pre-20
    The fastening element comprises a mounting element 1 connected to the threaded element 2, and a compression sleeve 3, the butt end of the spacer element 1 is connected to the rod-like element 4, which is made with the support 5 on the free end. A battery is placed on the rod-like element between the spacer element 1 and the stop 5. energy in the form of a coil spring 630
    squeeze. Rod-shaped. the element is placed coaxially with the threaded element and is made with the threaded section 7 on the side opposite to the stop, while the threaded section is screwed in 35
    axial threaded hole 8 of the threaded element, made in the form of a finger. The expansion element 1 is located on the rod-like element 4 s. possibility of axial movement. 40
    Between the threaded element 2 and the expanding sleeve 3 is placed a spring ring 9, the diameter of which is larger than the diameter of the threaded element 2,
    After placing the fastener in the hole 45 in the base part. 11 on the ceiling 12 set the subject 13. Then on the threaded element (finger). 2 screw the nut 14. When screwing the nut, the threaded member; 50 and the stop 5 move to the outlet of the hole. The force of the spring. 6 transmitted to the spacer 1 increases and the expanding sleeve 3 is firmly held by the spring ring 955 in the opening J. The increase in the force acting on the spacer 1 creates a correspondingly higher tension force.
    The opening 10 in the area of the expanding sleeve 3 can be turned along a cone, thereby providing a particularly strong expansion of the sleeve 3. Such a technique makes it possible to make a connection with a positive fit between the fastening element. cop and base part 11.
    If, in the area of a threaded element made in the form of a threaded pin, shock loads occur, then under their action the abutment 5, respectively, is retracted with a blow. However, since between the spacer 1 and the anvil 5 there is an energy accumulator in the form of a helical (helical) spring 6, the arising impacts are elastically absorbed. Due to this, the load of a large impact force is not able to cause displacement of the expanding sleeve 3 inside the hole 10. As a threaded element, instead of a threaded finger, a finger with double-sided internal thread can be used, but in this case, instead of a nut, a screw element should be used carving such a finger. In addition, the threaded section 7 can be removed from the bore 10 by means of a sleeve. However, in this case, the nut 14 should have a correspondingly reduced thread diameter.
    The compression spring stiffness coefficient must be such that the object fixed at noMODifi - the element does not load with its weight the energy accumulator beyond the limit of its elasticity. In this case, the fastener will be suitable for use in areas of high seismic risk.
