Bolt Anchors And Sleeves Patents (Class 238/377)
  • Patent number: 8840036
    Abstract: A screw anchor for concrete attachment in a railway sleeper and to a force-fit connection using a rail screw containing a threaded section with external threads disposed on an exterior of the screw anchor and internal threads disposed in the screw anchor; and an upper partial section without external threads which is disposed in a mounted state close to an anchor opening. The screw anchor utilizes material with high elasticity arranged in the upper partial section, wherein this material, when in a mounted state, forms an elevation which extends in an upward direction over an upper side of an end surface of the upper partial section and reduces a free opening section of the inner chamber of the upper partial section.

  • Patent number: 8814058
    Abstract: The invention relates to a plastic screw plug (6) for attaching a rail to a sleeper, in particular concrete sleeper, having an essentially cylindrical plug body which has at the head end a stem region (7) which preferably adjoins a plug crown (8) toward the bottom, and in the continuation of which stem region (7) has an outer thread (9) with which it can be turned out of or into the sleeper, and is provided with an inner thread (10) underneath the stem region (7) in order to receive a sleeper screw. The intention is to improve such a plastic screw plug, in particular, with regard to its operating properties such as uniform application of force into the sleeper, simpler mounting and replaceability, reduction of the risk of fracturing, and additionally to permit it to be used in a variable way.

  • Patent number: 7766249
    Abstract: A rail-carrying plate lies on an upper surface of a base. An anchor-bolt assembly has an elastomeric buffer sheet between the rail plate and the base upper surface and a bolt set in the anchor sleeve passing through the rail plate. An inner ring surrounds the bolt, bears directly on the base surface, is pressed downward by the bolt against the base surface, has an annular outwardly directed outer surface. An outer ring is transfixed by the bolt, has an annular inner surface spaced outward from the inner-ring outer surface, and bears upward on the rail plate. An annular elastomeric body between the inner and outer rings is bonded to the respective outer and inner surfaces thereof so that vertical displacement of the outer ring relative to the inner ring tends to self-center the two rings.

  • Patent number: 7389940
    Abstract: A method and a device for attaching an elevator guide rail to a substrate via a floating mount. The floating mount includes at least one of a base support, a side support, and a backside support. Each of the supports has a moveable part, a stop and a flexible element floatingly supporting the moveable part. Deforming forces cause the guide rail and the moveable part to move in a deforming direction deforming the flexible element until the deforming force exceeds a predetermined limit whereupon the stop limits further movement of the guide rail.

  • Patent number: 5738278
    Abstract: An anchor sleeve for a composite anchor is threaded in its inside surface and is anchored by at least one of an organic and inorganic mortar in a borehole formed in a concrete tie for rails or in a similar receiving material. The inside threaded sleeve (2) forms a load engagement means for an attachment member and is located in a trailing end region of the sleeve. The sleeve has two concentrically and consecutively arranged sealing elements (7, 9) at an opposite leading end of the sleeve and the sealing elements close off the leading end of the sleeve in a liquid-type manner. The sealing elements (7, 9) can be consecutively displaced out of sealing engagement at the leading end of the sleeve (2). In addition, a method for corrosion resistant anchorages employs the anchor sleeve.

  • Patent number: 5332153
    Abstract: The retention value of a screw previously inserted into a wooden railroad tie is increased by an axially extending sleeve ( 20 ) having an external thread ( 24 ) and an internal thread (25). The thread revolutions of the internal thread (25) are offset axially by half (h) the thread pitch (H) of the external thread (24). Due to this offset of the threads, the screw is positioned in the sleeve so that its threads are located between the external thread revolutions affording a new retention, while the external thread (24) seats within the thread previously formed in the wooden railroad tie by the screw.

  • Patent number: 5285964
    Abstract: The method relates to the laying of rails in a trench into which concrete is subsequently poured in order to fasten the rails. The method consists in laying adjustable-length ties (4) on the bottom of the trench (3), in roughly positioning the rails (14, 15) by means of block-supports, in fastening the ties to the rails by using tie-screws (10) and anchor sleeves (11) as bolts and nuts, in adjusting the length of the ties and in leveling the ties by means of auxiliary screws (18), and then in pouring the concrete, the auxiliary screws being subsequently removed. The ties are preferably pre-equipped with tie-screws, with sleeves and with rail-fastening clamps and the tie-screws and the sleeves may also be used for fastening tie-plates to the ties.

  • Patent number: 5042717
    Abstract: Fastening strap composed of a rod having a vertical rectilinear part (20) and a curved part which forms a spring and the end (10) of which grips the flange (25) of the rail to be fastened, after being tensioned as a result of the rotation of the strap above a ramp (30), the lower end of the rectilinear part being equipped with a heel (2) catching on a retaining surface (36) in the tie. The strap has an intermediate bearing point (6) which, during the rotation of the strap, bears on an abutment (38) or on a bearing surface of a metal sole plate. This intermediate bearing point ensures the stability of the strap during its rotation and in its tensioned position and, if an abutment is used, keeps this abutment in place.
