[0002]

2. Description of the Related Art In many cases, a structure composed of a plurality of components is integrated by connecting the components with wires. For example, in a sound insulation wall of a type in which sound insulation plates are fitted into grooves of opposing H-shaped columns and are laminated so as to be installed as a number of noise reduction measures for automobile traffic noise, the laminated sound insulation plates are connected to each other by wires and integrally formed. It is a sound insulation wall.

[0003] In this case, by connecting the sound insulating plates, it is possible to prevent the sound insulating plates from falling.

[0004]

However, when a plurality of structures are connected to each other by a wire as in the above-described sound insulation wall, the wire must be fixed. And
In order to stably fix the wire, it is often necessary to take special measures, such as providing fixing means, and there have been problems in cost and workability.

Accordingly, an object of the present invention is to provide a wire fixing tool which can easily fix a wire in a stable state, and a fixing method using the fixing tool.

[0006]

According to the present invention, there is provided a wire fixing device comprising: a wire having an enlarged diameter portion at a tip; a plate having a wire insertion hole having a diameter larger than the maximum diameter of the enlarged diameter portion; A fixing tool for fixing the fixed portion to a fixed portion, the fixed portion is made of a plate material bent so as to be able to sandwich the fixed portion in the thickness direction, and a through hole having a diameter larger than the maximum diameter of the enlarged portion. A slit continuous with the through hole and having a width smaller than the minimum diameter of the enlarged diameter portion and larger than the diameter of the wire.

Further, in the wire fixing method according to the present invention, the wire having the enlarged diameter portion at the distal end portion is formed into a plate-shaped covering having a wire insertion hole having a diameter larger than the maximum diameter of the enlarged diameter portion. A method of fixing to a fixed portion, comprising a plate material bent so that the fixed portion can be sandwiched in a thickness direction, the through hole having a diameter larger than the minimum diameter of the enlarged diameter portion, and the through hole And a fastener having a slit narrower than the minimum diameter of the enlarged diameter portion and wider than the diameter of the wire, and the through hole is provided in the wire insertion hole of the fixed portion. A first step of holding the portion to be clamped at a position where the fixed portion is sandwiched, and inserting the enlarged diameter portion into the through hole and the wire insertion hole, and a part of the wire is inserted into the through hole and the wire. A second step of passing through the insertion hole; and Is positioned slid to overlap, characterized in that it consists of a third step of the fixed state.

According to this fixture, when fixed to the fixed portion, the base end of the enlarged diameter portion engages with the peripheral edge of the slit, and the fixed portion is prevented from dropping out of the wire insertion hole, The wire can be fixed to the fixed portion. Further, according to this fixing method, the wire can be easily fixed to the fixed portion only by sliding the fixing tool. Furthermore, since the fixed portion can be fixed only by providing the wire insertion holes without providing a complicated shape fixing means, the cost can be reduced.

[0009] The slit is located above the through hole, and the plate has a portion in which the interval between the two pieces is smaller than the thickness of the fixed portion. You may make it slide downward, applying a force from above. In this case, in a state where the fixture is fixed, the two pieces of the plate material are strongly pressed to the portion to be fixed, so that the fixing strength can be increased. In addition, there is no restriction | limiting in the position which provides the part which the space | interval of both piece parts becomes narrower than the thickness of a to-be-fixed part, and it can be set as an optimal position according to a mounting situation. However, when the position is extremely close to the bent portion of the plate material, the pressing force of the two pieces to the fixed portion becomes weak. On the other hand, if the distance between the two sides in the opening is smaller than the thickness of the fixed portion, it becomes difficult to fit the fixing tool into the fixed portion. Therefore, it is preferable to set the position near the middle between the opening and the bent portion.

[0010] The slit may be located on the side of the through-hole, and in the third step, the fixture may be slid to the side. In this case, even when the fixture is displaced in the vertical direction due to the vertical force acting on the wire, the through hole and the wire insertion hole are in a positional relationship where they do not overlap, so that the wire can be prevented from falling off. Therefore, the fixing strength can be increased without strongly pressing both the pieces of the plate material to the fixed portion. Note that this operation effect takes into consideration that a force is applied in the vertical direction when the structure is in a natural state.

[0011] The fixed portion is a sound insulating wall of a type in which a sound insulating plate is fitted into grooves of opposed H-shaped columns and laminated.
It may be a web of a mold support. In this case, the present invention can be applied to an H-shaped support having no wire fixing means only by providing a wire insertion hole. In addition, even when the present invention is applied to an existing sound insulation wall, it is not necessary to replace it with a new H-shaped support provided with a fixing means, and the cost can be reduced.
