Definitions

  • a rail fastening attachment for fastening rails on concrete ties and the like employing an angular depression having a straight wall portion for accommodating a base plate which contacts the rail laterally and a clamp member which is secured on the base plate and also contacts a lateral flange of the rail.
  • the present invention relates to a rail fastening arrangement particularly for fastening .rails on concrete ties without a support plate. More particularly the present invention relates to an arrangement for fastening rails on concrete ties or the like in which guide plates are fastened into the unreinforced concrete-slab surface by means of bolts which are anchored into the concrete body and which press the rail onto the tie.
  • Constructions with lateral guide plates are well known in the art. Their purpose is in general to accomplish a reduction in the cost of construction as compared with under plate construction, such as for example, rib plates. Up to now, however, such constructions did not gain acceptance.
  • the guide plates in the tie constructions previously described, permit rapid and exact mounting of the rail.
  • the lower nut tightens the guide plate directly with a very high degree of tension.
  • the upper nut exerts only a slight force upon a clamp plate.
  • This type of attachment is more expensive because of the high cost of the parts and also poses new problems, because it requires meticulous care of the thread portions.
  • a further problem which arises is in determining whether the lower nut is safe, as forces are constantly exerted over long periods of time. If no suitable means are provided for retaining and maintaining the tension between the anchorage and the lower nut, even a small grain of sand, which might come to be on the relatively rough surface, will be sufficient to cause a substantial loss in the tensioning force. Because the tightening of the lower nut is very complicated it is often neglected.
  • the present invention has for its purpose to provide a fastening arrangement for rails of the type initially described which can easily be installed and easily be removed; which is economical to produce and maintain; which is dependable and will maintain the required tension and will completely resist both the side forces and the rotational forces imposed upon it.
  • the guide plate itself is fitted to the tie and seated in such manner as to obtain substantially high resistance to lateral movement and rotation.
  • the guide plate in accordance with this invention is so shaped that its cross-section when viewed at a right angle to the rail, will display an angular partially angular profile which projects upwardly displaying a substantial angle of inclination on each of its sides or the plate may be provided on its base with ribs which run parallel to the axis of the tie and which, if desired, may be angled.
  • this construction is to divert all lateral forces that may arise, by means of a dependable and constant screw thrust effect, so that the resultant force is directed against the interior of the concrete body at a very inclined angle. If the guide plate is shaped in such a manner that the resultant force will be at right angles to the horizontal and act upon a substantially large transmission area, then large lateral forces may be absorbed without danger of damage by an unreinforced concrete body.
  • the desired effect can be improved by a construction in which the tie bolts are arranged at an angle. In this manner one provides an inward bias to the entire fastening mechanism which directs itself inward towards the rails.
  • the guide plates are prefera ly made from rolled steel sections. Of course, it is possible to produce such guide plates from steel forgings or castings and even from plastic materials.
  • an embedded bolt or the well known hammer head bolt for which secure anchoring is provided at or in the tie structure.
  • the hammer head bolt is inserted from above with its head in the tie body and secured in the interior of a perforated plate embedded in concrete.
  • the bolt is orientable in the tie axis. This makes possible the release of the bolt shanks from bending stress and shearing strain.
  • the clamp member is preferably designed in such manner that it is arched or alternatively curved and positioned under the nut.
  • FIGURES 1, 3, 5, 7, 9 and 11 are vertical sectional views and FIGURES 2, 4, 6, 8, l and 12 are respective top views.
  • FIGURES 1 and 2 the rail attachment is accomplished by means of a partially angular guide plate, a rigid clampplate and a resilient washer.
  • FIGURES 3 and 4 illustrate an arrangement in which the clamp plate is flexible and a washer is employed.
  • FIGURES 5 and 6 illustrate a rail attaching arrangement with a ribbed guide plate, a flexible clamp plate ing an S-shaped resilient clamp plate and a hollow troughshaped guide piece.
  • FIGURES l1 and 12 illustrate an arrangement similar to the one shown in FIGURES 9 and 10 in which a trough-shaped hollow guide plate is employed in combination with an angular or inclined bolt.
  • a rail 1 is positioned upon and rests on a cement tie 2. Between the rail and the tie an elastic intermediate member 3 is disposed which extends under the entire width of the rail over the tie.
  • a highly resilient spring washer 11 is provided under nut 10; The described manner of positioning prevents the rotation or shifting of the guide plate 4 which is aided by angular portions 12 and 13 on opposing sides.
  • the guide plate is accommodated in the concrete tie surface in depression 12a in a relatively shallow manner to prevent a weakening of the tie but at a depth sufficient to furnish substantial resistance to rotation.
  • the outer substantially angular portion 14 of the guide plate is positioned against a small abutment 15 in the concrete tie.
  • the desired degree of inclination of portion 14 as well as the adjacent wall section of depression 12a is such that an angle of at least ninety degrees is formed with portion 13 and its adjacent wall section.
  • FIGURES 3 and 4 the W-shaped bent rod, which serves as a flexible clamp plate 16.
  • the nut is suitably provided with a washer 17 below the nut.
  • Legs 18 of rod 16 press againstthe rail base and intermediate loop 19 partially circumscribes the shaft of the bolt.
  • Loop portions 20 are drawn somewhat downwardly and are accommodated on the upper groove in theguide plate 4. This prevents turning or shifting of the clamp plate.
  • the intermediate loop 19 curved or bent as shown at 21 causes the screw thrust to be centered.
  • the ties and the lateral guide plates are identical for the constructions of FIGURES 1 and 3 so that their interchangeability is assured.
  • the ribbed guide plate 22 is a rolled, cast metal piece positioned at right angles to the rail which can be easily produced. It carries on its lower portion ribs 23 which are parallel to the axis of the tie. These ribs prevent turning and shifting and they fit into corresponding narrow slots 23a in the tie surface and reduce the flexibility of the tie only slightly.
  • the outer portions 24 of the ribs are angled in such a manner that resultant forces are introduced into the concrete body at a particularly desirable angle.
  • the-re is interchangeable with resilient clamp plate 25 in combination with a bushing 26, the W-shaped, bent rod-like resilient clamp member 27 as particularly described in FIGURE 7.
  • a ridge 28 is provided on the upper surface of the guide plate.
  • the shape of the W-shaped clamp member 27 corresponds to the constructions illustrated in FIGURES 3 and 4, however, this piece is not as severely angled.
  • the ties and lateral guide plates in these particular constructions are the same, so that there is the possibility of component exchangeability.
  • FIIGURES 9-12 conclude the embodiments with S- shaped resilient clamps 32 and 47.
  • An arrangement is shown in which the tie surface has been provided with shallow depression 29 and the correspondingly shaped guide member 30 is inserted therein.
  • An upwardly turned edge 31 of the member serves as guide for the rail.
  • Nut 36 can be tightened until the vertical portion 37 of clamp 32 is tightly pressed against the guide plate. In this manner a substantial amount of spring tension is obtained which is greater than could otherwise be achieved.
  • FIGURES 11 and 12 an arrangement is shown in which a concave guide plate is employed which is sub stantially L-shaped having a slightly smoothed-out cast profile 39 and is in depression 3911 so as to be contiguous therewith.
  • the tie bolt 40 is angled and inclined in such manner and preferably at an angle of greater than ninety degrees with respect to the vertical axis of the rail, to provide for effective biasing of the entire construction whereby the tensioning forces are directed inwardly against the rail.
  • the S-shaped clamp 41 is also provided with three definite pressure points 42, 43 and 44.
  • the weakening effect of the hole within the spring plate of clamp 41 is counteracted by a second spring plate 45 and this also increases and reinforces the resiliency of the center portion of the clamp.
  • This second spring plate has a bent portion 46 which fits into the clamp plate. Its upper end 47 is bent over clamp 41 and plate 39 so that any rotational and shifting movement of the arnangement is eliminated.
  • Below the nut 48 is a smooth washer 49 with a rounded contacting portion which fits the shape of spring plate 45. In this manner the forces, which are exerted, will be distributed evenly over the entire area of the spring and this assures that the forces are directed along the screw axis.
  • the arrangement also provides for a small abutment 50 in the surface of the tie in a manner that the grooves in the tie surface will not too deeply penetrate the tie body and thereby reduce its carrying strength.
  • a rail attachment for concrete ties and the like comprising a substantially angular depression having at least one substantially straight wall portion in the upper surface of said tie, a plate member positioned in and adapted to conform substantially to said depression and provide a lateral abutment surface for said rail, a clamp member including a flexible slightly curved rod with at least two extending portions adapted to engage each said plate member and said rail and means secured to said tie and extending through both said plate and clamp member to urge said clamp member against said plate member and against said rail.
  • a rail attachment for concrete ties and the like comprising a substantially angular L-shaped depression having at least one substantially straight wall portion in the upper surface of said tie, a substantially L-shaped plate member positioned in and adapted to conform substantially to said depression and provide a lateral abutment surface for said rail, a substantially S-shaped clamp member providing two contact points on said plate member and one contact point on said rail and means secured to said tie and extending through both said plate and clamp member to urge said clamp member against said plate member and against said rail.
  • the rail attachment as defined in claim 2 further including a spring plate overlying said clamp member and having an end portion disposed over an end of said clamp member and said plate member.
  • a rail attachment for concrete ties and the like for supporting rails comprising at least one narrow slot in the upper surface of said tie disposed with the longitudinal axis substantially transverse to said rail, a plate member having a rib adapted to :fit in said slot and providing a lateral abutment surface for said rail, a clamp member adapted to engage said plate member and an adjacent portion of said rail and means secured to said tie and extending through both said plate and clamp members to urge said clamp member against said plate member and against said rail.
  • clamp member comprises a flexible slightly curved rod with at least two extending portions adaptedto engage each said plate member and said rail.
  • clamp member comprises a first flexible portion for engagement with said rail and a second flexible portion for engagement with said securing means.
  • clamp member comprises a flexible portion for engagement with said rail and a concave portion for engagement with said securing means.
