A soundproofing apparatus for a rail according to the present invention comprises a first soundproofing member having a sound absorbing mat and a sound insulating cover attached to a required portion of a surface of a rail from one side surface thereof, And a fixing member for fixing the sound-insulating member, wherein the fixing member comprises a first fixing member and a second fixing member, and the fixing member is made of a first fixing member and a second fixing member, 1 fixing member has a horizontal portion inserted into the lower surface of the rail bottom portion and a rising portion assigned to the sound insulating cover of one sound insulating member formed continuously to the end portion of the horizontal portion, And a rising portion which is connected to an end portion of the horizontal portion and is assigned to the sound insulating cover of the other soundproofing member, At least one convex portion is formed on one fixing member and the other fixing member is provided with a concave portion to be fitted to the convex portion so that the first fixing member and the second fixing member overlap each other And is detachably fitted thereinto.
In order to fix the two soundproofing members using the two fixing members, it is usually necessary to form a mating portion on each fixing member and to connect the mating portions with each other by means of bolts. However, The first fixing member and the second fixing member are detachably fitted to each other so that the fastening by the bolt and the fitting of the fixing member for the bolt can be eliminated. This eliminates the need for a tool for bolt fixation and screw fixation, thereby improving the workload and complexity of the construction, reducing the number of protruding portions compared to the rail, and preventing the problem of obstructing the track maintenance can do.
It is preferable that the portion protruding from the rail is within 10 mm from the rail bottom. By fixing the two fixtures using the above-described two fixtures, this condition can be easily satisfied.
In order to make the structure detachably fitted, for example, at least one convex portion is formed on one (the horizontal portion and / or the rising portion) of the first and second fixing members and the other convex portion So that a concave portion to be fitted is formed. The number and shape of the convex portion and the concave portion are not particularly limited and may be, for example, one convex portion on one side and one concave portion on the other side, and two convex portions on one side and two concave portions on the other side And one convex portion and one concave portion may be formed on one side, and one concave portion and one convex portion may be formed on the other side.

The concave portion is not necessarily required to have a bottom surface in contact with the tip end surface of the convex portion, and may be in the form of a hole or a slit.
It is preferable that at least one of the first and second fixing members is provided with a bent portion which is formed at an end portion of the semi-rising portion side of the horizontal portion and restricts the movement of the fixing member toward the rising portion side.
According to the fixing member in which the bent portions are formed, since the soundproofing members can be sandwiched between the both sides of the rail bottom face portion in the rising portions and the bent portions, it is possible to fix them to some extent without the other fixing members, It is possible to further secure the fixing by the combination with the fixing member of the fixing member.
It is preferable that the bent portion is formed on the second fixing member and is in contact with the rising portion of the first fixing member from the outside. By doing so, both of the first and second fixing members are prevented from moving in the direction orthogonal to the rails, and the fixing is strengthened.
It is preferable that the first convex portion of the at least one convex portion is formed on the outer surface of the rising portion of the first fixing member and the first concave portion is formed on the bent portion of the second fixing member to fit the first convex portion Do. In this way, in addition to the effect of preventing the movement of the respective fixing members in the direction orthogonal to the rails by the bent portions, the movement of the respective fixing members in the direction orthogonal to the rails due to the fit between the first convex portions and the first concave portions It is possible to obtain an effect of preventing an increase in the thickness of the film.
The second convex portion of the at least one convex portion is formed so as to protrude in the horizontal direction from the end portion of the semi-rising portion side of the horizontal portion of the first fixing member, and the second concave portion fitted to the second convex portion And it is preferably formed at the lower end of the rising portion. With this arrangement, the relative movement of the rails of the respective fixing members in the longitudinal direction is reliably prevented by the engagement of the two convex portions and the two concave portions, and the positioning is reliably performed.
The method for attaching the soundproofing device of the above-described rail to the rail in which the second convex portion and the second concave portion are fitted is characterized in that the horizontal portion of the first fixing member is inserted from the one side of the rail downward The horizontal portion of the second fixing member is inserted below the horizontal portion of the first fixing member from the other side of the rail, and the second recess of the second fixing member is inserted into the first fixing member The gap between the end of the horizontal portion of the first fixing member and the end of the rising portion of the first fixing member and the end of the rising portion of the second fixing member do not exist, A step of providing a second fixing member so as to have a clearance between the end portions on the side of the bending portion of the horizontal portion of the fixing member and a step of setting the other end side of the tool as a point The end portion of the horizontal portion of the first fixing member on the side of the rising portion and the end of the second portion of the second fixing member are brought into contact with the end of the horizontal portion of the second fixing member, And removing the gap between the end portions on the bending portion side of the fixing member.
