JPH0967811A - Metal fixture of exterior finishing plate - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent the transmission of vibration directly to an exterior finishing plate without boring a hole in a post by press-contacting the front end of a bolt to a flange of the post to fix a metal fixture thereto, and mounting the exterior finishing plate to the post through a washer member. SOLUTION: One leg section 12 is brought into contact with the inside of a flange 3a of a post 3, a bolt 30 is turned and is press-contacted to the outside of the flange 3a, and the flange 3a is held between the bolt 30 and the leg 12. The rear end of the bolt 30 is inserted into a mounting hole 2a of an exterior finishing plate 2, and a nut 33 is screwed in the bolt 30. Then, the exterior finishing plate 2 is pushed against to the other leg 11 of a holding member 10 together with one leg 21 of a washer member 20. By this constitution, vibration is not transmitted directly to the exterior finishing plate 2, and noises caused by resonance, etc., can be prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting bracket for an exterior plate mounted on the outer surface of a soundproof wall such as a highway.

[0002]

2. Description of the Related Art As shown in FIG. 4, soundproof walls 1 for blocking vehicle noise are provided on both sides of a highway H. An exterior plate 2 made of a corrugated iron plate is attached to the outer surface of the soundproof wall 1.

In order to attach the exterior plate 2, as shown in FIGS. 5 and 6, a large number of attachment holes 3b are provided in the support columns 3 made of H-shaped steel and arranged upright at equal intervals. Then, the bolt 4 is passed through the hole 3b and the nut 5 is tightened.

[0004]

According to the above method, it is necessary to provide a large number of mounting holes in the support column 3, for example, 64 mounting holes for each support column, which requires a great deal of labor for the work at the site.

Further, the exterior plate 2 is directly bolted to the support column 3,
Since they are connected by the nuts, vibration of the road due to the vehicle is transmitted from the column 3 to the exterior plate 2 to cause a resonance action, and the noise thereof is also transmitted to the surroundings.

[0006] Therefore, an object of the present invention is to make it possible to attach an exterior plate without providing a hole in a column, and further to prevent resonance of the exterior plate.

[0007]

In order to solve the above-mentioned problems, the fitting of the present invention comprises a substantially U-shaped holding member and a substantially U-shaped washer member which is loosely fitted to one leg of the holding member. , A through hole is provided in one leg of the holding member,
A through hole corresponding to the through hole of the holding member is provided in one leg of the washer member, and a nut is fixed to the other leg of the washer member, and the through hole of the washer member and the through hole of the holding member are inserted. And, the tip of the bolt that screw-engages with the nut is pressed against the flange of the column so that the flange of the column is sandwiched between the other leg of the sandwiching member, and the rear end of the bolt is externally mounted. The exterior plate is pressed against one leg of the washer member by inserting the nut into the mounting hole of the plate and tightening the nut with the bolt.

[0008]

[Operation] Since it is possible to fix the fixture to the support by pressing the tip of the bolt against the flange of the support, it is not necessary to provide a mounting hole in the support.

Further, since the exterior plate is attached to the support via the washer member, vibration is not directly transmitted to the exterior plate, and it is possible to prevent noise from being generated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS.

As shown in FIG. 1, the fixture of the present invention comprises:
The holding member 10 has a substantially U-shape, a washer member 20 having a substantially U-shape that is loosely fitted to one leg 11 of the holding member 10, and a bolt 30.

On one leg 11 of the holding member 10,
A through hole 13 is provided, a through hole 23 corresponding to the through hole 13 is provided at one leg portion 21 of the washer member 20, and a nut 24 is fixed to the other leg portion 22. (See Figure 2). The through hole 23 is preferably a long hole. Further, the washer member 20 is preferably formed of a material having a good spring property such as spring steel.

The bolt 30 preferably has a sharp tip 31 and a rear end provided with a hexagonal hole 32 into which a wrench can be inserted. Instead of the hexagonal hole 32, a prismatic portion having a diameter smaller than that of the bolt 30 may be formed.
In the figure, reference numeral 33 is a suitable nut that can be screwed into the bolt 30.

Then, as shown in FIG. 2, the washer member 20 is loosely fitted to the one leg portion 11 of the holding member 10, the positions of the through hole 13, the through hole 23 and the nut 24 are aligned, and the bolt 30 is fixed. Insert the nut 2 through the through holes 23 and 13.
When the screw is engaged with 4, the fixture is completed.

In order to attach the exterior plate with the above-mentioned fixture, as shown in FIG. 3, the other leg 12 is applied to the inner surface of the flange 3a of the column 3, and the bolt 30 is rotated by a wrench or the like to The tip end is pressed against the outer surface of the flange 3a to hold the flange 3a.

Then, the bolt 3 is attached to the mounting hole 2a of the exterior plate 2.
When the nut 33 is threadedly engaged with the bolt 30 and tightened through the rear end portion of 0, the exterior plate 2 is pressed toward the one leg portion 11 of the holding member 10 together with the one leg portion 21 of the washer member 20. It

[0017]

According to the present invention, as described above, the substantially U-shaped washer member is loosely fitted to the one leg portion of the substantially U-shaped holding member, and the one leg portion and the washer member of the holding member are attached. Since the bolt is inserted through and the pillar is held by the other leg of the holding member and the tip of the bolt, the fixture can be fixed without providing a hole in the pillar.

Further, since the washer member is loosely fitted to one leg of the sandwiching member, when the bolt is inserted into the mounting hole of the exterior plate and tightened with the nut, the exterior plate is inserted through the washer member. Since it is attached, vibration is not directly transmitted to the exterior plate, and noise due to resonance or the like can be prevented.
