Description

  The present invention relates to, for example, a fixing tool and a fixing method for fixing a damping material by being attached to a rail of a railway.

  In the case of the soundproofing method in which the damping material is attached to the rail in the realization field, the surface condition is inferior (rust, dust), so there is a risk of the damping material falling off due to a decrease in adhesive force or poor enforcement. Fixing tools are used to prevent this. In the fixing tool, plate-like members are separately applied from both sides of the rail, and both the plate-like members are tightened with bolts and nuts (for example, see Toku literature 1).

In such a method, there are problems such as complicated construction and the need for maintenance because bolts and nuts are loosened.

<Embodiment 1>
The first embodiment is shown in FIGS.

  The rail R is composed of a head portion Rt, an abdominal portion Rw, and a bottom portion Rb that are successively connected from top to bottom. A pair of left and right vibration damping materials S are attached from the left and right side surfaces of the abdomen Rw to the upper surface of the bottom portion Rb.

  The fixture is composed of a first fixing member 11 that covers the entire bottom surface of the rail bottom Rb, and a second fixing member 12 that has an L-shaped cross-section that is covered by the right edge of the rail bottom Rb. Has been. A first fitting member 21 having a leftward U-shaped cross section is provided at the right edge of the first fixing member 11. The left edge portion of the first fixing member 11 is provided with an inverted L-shaped fitting portion 22 having a cross-section that is fitted to the left edge portion of the rail bottom portion Rb. A right protruding flat plate-like second fitting portion 23 fitted with the first fitting portion 21 is provided at the lower end portion of the second fixing member 12.

When using the fixture, the first fixing member 11 is applied to the lower surface of the rail bottom Rb, and the fitting portion 22 is fitted to the left edge of the rail. At this time, the portion of the first fixing member 11 to be the first fitting portion 21 is not U-shaped as shown by the chain line in FIG. It extends straight to extend to the right. Next, the second fixing member 12 is covered on the right edge of the rail bottom Rb, and the second fitting portion 23 is overlaid on the portion of the first fixing member 11 that is to become the first fitting portion 21. . Then, a portion of the first fixing member 11 that should be the first fitting portion 21 is bent upward to form the first fitting portion 21. Thereby, both fitting parts 21 and 23 are fitted.

As shown in FIG. 2 (a), in a state where both the fitting portions 21 and 23 are fitted, the second fitting portion 23 is made larger than the size of the first fitting portion 21 in the rail length direction. In this case, both end portions of the second fitting portion 23 are protruded in the rail length direction from the first fitting portion 21, respectively. The first fitting portion 21 and the second fitting portion 23 are provided with a function of preventing detachment by bending both the protruding portions downward.

In order to fulfill the function of preventing slipping, instead of projecting both end portions of the second fitting portion 23, only one side of the projecting portion is projected as shown in FIG. Only the part may be bent. Further, as shown in FIG. 2 (c), the tip end portion of the second fitting portion 23 is formed so as to have an angle with respect to the rail length direction, and is superposed on the first portion so as to overlap the first portion. The fitting portion 21 may be formed.

  FIG. 3 shows a fixture according to a modification. The fixture according to this modification is constituted by a first fixing member 31 covered on the right half of the lower surface of the rail bottom Rb and a second fixing member 32 covered on the left half of the lower surface of the rail bottom Rb. . The first fixing member 31 is provided with a first fitting portion 41 having a U-shaped right section at the left edge portion. The right edge of the first fixing member 31 is provided with a first fitting portion 42 having an L-shaped cross section that is fitted to the right edge of the rail bottom portion Rb. A left fitting cross-section second fitting portion 43 is provided on the right edge portion of the second fixing member 32. The left edge portion of the second fixing member 32 is provided with an inverted L-shaped second fitting portion 44 having an inverted cross section that is fitted to the left edge portion of the rail bottom portion Rb.

  In order to use the fixture according to this modified example, after the first fitting portion 42 and the second fitting portion 44 are fitted to the corresponding portions of the rail bottom portion Rb, as shown by the chain line in FIG. The first fitting portion 41 and the second fitting portion 43 are fitted by bending the portion to be the fitting portion 43 into a U shape from a straightly extended state.
