小形になる。 In addition, both the front and rear ends of the rail pressing spring are thin and wide, and the center part is thick and narrow, so the spring constant at the spring ends is reduced, and the stress at the center of the spring is alleviated. The shape of the fixing anchor to which the central portion of the spring is attached also becomes relatively small.
更に前記レール押えばねの加圧点は従来のよう

（実施例） 以下本発明を図示の実施例について説明する。(Example) The present invention will be described below with reference to the illustrated embodiments.

するようにレール押えばね５が装着される。 In FIGS. 1 and 2, a rail 3 is installed on a sleeper 1 via a track pad 2. A gate-shaped fixed anchor 4 is welded or embedded in the sleeper 1, and the anchor 4 is made of glass fiber roving, in which both front and rear ends 5a, 6b are thin and wide, and the center part 5c is thick and narrow. Reinforced epoxy resin, polyester resin, vinyl ester resin, etc., a variable cross-section rail press spring made of reinforced plastic 5
The central part 5c of the spring 5 is supported, the front end 5a of the spring 5 is supported on the rail bottom upper surface 3a, and the rear end 5b is
A rail pressing spring 5 is attached so that it contacts a protrusion 6 that is welded or embedded in the sleeper 1.

若干小径の凸面部４ａで支承する。 At the same time, a horizontal pressing spring 8 made of reinforced plastic is interposed between the rail 3 and the fixed anchor 4, and the rail contact surface is formed as a convex surface 8a with a large curvature, and the concave curved surface 8b is formed on both sides of the opposite side. Each of the concave curved surfaces 8b is supported by a convex surface portion 4a provided on the fixed anchor 4 and having a slightly smaller diameter than the same surface 8b.

力を得るものである。 Then, the tip 9a of the forked crowbar 9 is inserted into the groove 7a provided at the end of the fastening material 7, and the fastening material 7 is rotated so that the long axis is positioned vertically, and the rail pressing spring 5 is rotated. A predetermined fastening force is obtained by lifting the rear end portion 5b.

しいが、両者は相反する事項で、ばね定数を小さ
くするためには断面を小さく、長尺にするとよい
が、応力が増加し、また応力緩和のために断面を
大きくするとばね定数が大きくなる。 The basic performance of a rail pressing spring is to have a large spring constant, that is, a large deflection, and a small generated stress, but these two are contradictory, and in order to reduce the spring constant, it is better to make the cross section smaller and longer. However, stress increases, and if the cross section is made larger to relieve stress, the spring constant becomes larger.

ある。 The illustrated rail presser spring 5 is reinforced with glass fiber roving reinforcement, which has characteristics such as a small bending elastic modulus, easy molding into products with modified cross-sections, high material fatigue strength, and insulation properties. By being made of plastic, the drawbacks of conventional steel springs are eliminated.As mentioned above, both the front and rear ends 5a, 5b of the rail presser spring 5 are formed into thin and wide parts, and the central part is made of thin and wide parts. By forming the rail presser spring 5 with a thick wall and a narrow width, the spring constant at the tip of the rail presser spring 5 is reduced, and the stress in the center part is alleviated.
By forming the portion 5c narrowly, the fixed anchor 4 that supports the portion 5c can be made relatively compact.

なる。 Furthermore, since the pressure point of the rail pressing spring 5 is at the rear end, a small spring constant can be obtained even with a simple shape, and the bending amount to obtain the same rail pressing force is large, and the tolerance of each part of the rail fastening device can be adjusted. Variations in rail holding force due to influence are reduced. Further, when the distance between the front end 5a of the rail pressing spring 5 and the central portion 5c supported by the fixed anchor 4 is l1 , and the distance between the central portion 5c and the rear end 5b is l2 , then l2 is
By making l larger than 1 , the spring constant of the rail pressing spring rear end portion 5b can be further reduced. Also, the spring rear end 5b is used to obtain the same rail holding force.
Since the pressing force is reduced, the fastening work performance is improved.
なおl2／l1は1.2〜1.5程度が望ましい。またばね
全長にわたつて厚さ×幅、すなわち断面積が一定
になるようにすれば連続成形が容易になる。 Note that l 2 /l 1 is preferably about 1.2 to 1.5. Continuous molding becomes easier if the thickness x width, that is, the cross-sectional area, is made constant over the entire length of the spring.

A protective layer 5d made of a synthetic resin such as polyamide or Teflon, which has good lubricity, is adhered to the contact surface. Depending on the track conditions, a cushioning material with a high coefficient of friction such as synthetic rubber may be attached.

A metal fitting 5' holding a rail holding part and a lateral pressure receiver is molded integrally with the rail pressing spring 5 on the front end 5a, and this shows the case where it is used both to protect the rail sliding part and as a lateral pressing spring to be described later. . At this time, the joint between the metal fitting 5' and the reinforced plastic part can be formed into an uneven surface shape to generate shear resistance, thereby making it possible to integrate the two.

As shown in FIG. The distal end 9a of the crowbar 9 is engaged with the locking part 7a provided in the locking part 7a, and the fastening member 7 is rotated by the crowbar 9 as shown in FIGS. 5B and 5C, so that the major axis is vertically moved. By positioning it, the rear end of the rail pressing spring 5 is lifted to obtain a predetermined rail pressing force.

A concave portion 10 is provided on the contact surface, and a slight flat portion 7b is provided at the long-diameter end of the fastening member 7, so that the fastening member 7 is free from reversal or overturning and is stable against train vibrations. The tightened state is maintained.

対抗するものである。 Conventionally, in the lateral pressure mechanism, the fixed anchor 4 or the tie plate shoulder directly contacts the bottom side edge of the rail, but it is common to insert a steel lateral pressure block between the two, which improves insulation performance and lateral spring function. However, in the illustrated embodiment, the rail contact surface of the horizontal pressing spring 8 is formed into a convex surface 8a with a large curvature R1 , and concave curved surfaces 8b with a curvature R2 are formed on both sides of the opposite surface. The concave curved surface 8b is supported by convex surface portions 4a with a curvature R 3 slightly smaller than the same surface 8b provided on both sides of the fixed anchor 4, and the concave curved surface 8b is further sandwiched between the concave curved surfaces 8b of the horizontal pressing spring 8. An appropriate gap α is provided between the central portion 8c and the central portion 4b between the convex portions 4a of the fixed anchor 4, allowing bending deformation of the lateral pressing spring 8, elastically supporting lateral pressure at all times, and , it suppresses excessive bending deformation against significant lateral pressure and counteracts it by increasing the compressive strength of the entire cross section.
