DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sound-insulating panel fixing bracket for fixing a large number of sound-insulating panels constituting a sound-insulating wall to be installed on a side edge of a highway, a general road or a railway line. is there.

[0002]

2. Description of the Related Art As shown in FIGS. 9 and 10, a conventional sound insulating wall has a road (arrow R) standing upright on a side edge of a road or the like.
A large number of sound insulation panels 52 are hung on pillars 51 formed to bend in the direction. The column 51 has an H-shaped cross section, and each of the grooves 5
3 and 53 are erected so as to face each other. In this manner, both end edges 52a, 52a of the substantially rectangular sound insulation panel 52 are provided between the concave grooves 53, 53 of the adjacent columns 51, 51.
Into the road (arrow R), and insert the sound insulation panel 5
The sound-insulating panels 52 are fixed in such a manner that the sound-insulating panels 52 are not rattled by sandwiching a metal fitting 54 made of a resilient leaf spring in a gap between the two end edges 52a and the concave grooves 53. ... are stacked to form a sound insulation wall.

[0003] The fixing bracket 54 is formed by connecting a strip-shaped iron plate to the support 5.
The first groove 53 and the sound insulation panel 52 are bent substantially in a U-shape so as to have substantially the same distance (see FIG. 9), quenched to impart elasticity thereto, and then rusted. It has been subjected to a surface treatment such as zinc plating for stopping or a coating treatment.

[0004]

However, the above-mentioned conventional metal fitting 54 is formed by press-forming a strip-shaped iron plate, followed by quenching / tempering, pickling, hot-dip galvanizing or painting. However, there is a problem that the manufacturing cost is likely to increase due to the large number of manufacturing steps. In addition, the fixing bracket 54 manufactured by such a conventional manufacturing method uses so-called hydrogen due to hydrogen generated during pickling for the purpose of removing an oxide film formed on the surface during quenching and tempering. In many cases, it is brittle, and there is a risk that cracks may occur during use, causing breakage, and there is a problem that the rate of occurrence of defective products with high strength is high.

[0005] Further, a fixing bracket 54 which has been subjected to a galvanizing treatment.
If the metal is fixed in the concave groove 53 of the iron column 51 and exposed to wind and rain outdoors for a long time in a state where the two metals are in contact with each other, the fixing metal 54 gradually corrodes, and the elasticity is increased. Therefore, there is a problem that the sound insulation panel 52 is rattled.

[0006] On the other hand, the sound insulation panel 52 sandwiched between the lower portions of the columns 51 is often damaged when an automobile or the like collides with the sound insulation wall. However, when the damaged sound insulation panel 52 is repaired and replaced, the sound insulation panel 52 sandwiched in the lower stage cannot be removed unless the sound insulation panel 52 sandwiched between the columns 51, 51 is sequentially extracted from the upper sound insulation panel 52.
Therefore, there is a problem that even when one of the sound insulation panels 52 is repaired and replaced, the repair work time is extremely long.

The present invention has been made in view of the above problems, and simplifies the manufacturing process, improves the reliability in terms of strength, and easily repairs and replaces even those sandwiched in the lower stage of a column. It is an object of the present invention to provide a metal fitting for fixing a sound insulation panel.

[0008]

In order to achieve the above object, a metal fitting for a sound insulation panel according to the present invention is formed by bending a strip-shaped steel plate to form an insertion portion comprising a vertical insertion portion and an inclined insertion portion. Forming an inner supporting portion bent from the upper portion of the inclined insertion portion so as to have a substantially vertical cross-sectional shape toward the vertical insertion portion, and continuously forming the vertical insertion portion from the upper portion of the vertical insertion portion. The gist of the present invention is that each of the retaining portions is formed so as to protrude laterally with respect to the portion. In addition, it is desirable to form a ridge bead in the longitudinal direction of the insertion part of the fixture. The fixing bracket may be formed of a stainless steel plate, or a wire insertion hole may be formed in a retaining portion of the fixing bracket.

The edge of the sound insulation panel is inserted into the groove of the column, and the sound insulation panel is moved to one inner edge of the groove.
The fixing bracket is inserted into the gap between the groove and the sound insulation panel from the insertion portion, and the sound insulation panel can be fixed in the groove of the column by the elastic force of the vertical insertion portion and the inclined insertion portion. be able to.

According to the above structure, although a strip-shaped steel plate is formed by bending, it has elasticity and a predetermined mechanical strength without quenching / tempering, plating or surface treatment. It is possible to prevent rattling of the panel. In addition, since the inclined insertion portion is not narrower than a predetermined interval due to the ridge bead and the inner support portion formed at the vertical insertion portion and the inclined insertion portion of the fixing bracket, the sound insulation panel is connected to the groove of the support column. By fixing to the side, it is possible to prevent rattling of the sound insulation panel.

[0011] When the fixing bracket is formed of a stainless steel plate, it can withstand long-term use without rust. In the case of attaching a wire insertion hole to the retaining part of the fixing bracket, when attaching the sound insulation panel to the support, the wire is inserted through this wire insertion hole, so that the fixing bracket is attached or repaired and replaced. Can be prevented from falling.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of an embodiment of a metal fitting for a sound insulating panel according to the present invention.
FIGS. 1 to 5 show an embodiment of the first invention relating to a metal fitting for a sound insulation panel according to the present invention. In the drawings, reference numeral 1 denotes a fixing bracket formed by bending a stainless steel strip steel plate into a desired shape so as to have elasticity.
The fixing bracket 1 forms an insertion portion 4 composed of a vertical insertion portion 2 and an inclined insertion portion 3, and continuously connects the inner support portion 5 from the upper portion of one of the inclined insertion portions 3 to the other vertical insertion portion 2. The retaining portions 6 are formed by projecting from the upper portion to the side continuously.

The insertion portion 4 is formed by bending a strip-shaped steel plate so that the vertical cross-sectional shape becomes substantially V-shaped to form the vertical insertion portion 2 and the inclined insertion portion 3. A ridged bead 7 is formed in the longitudinal direction of the vertical insertion portion 2, and a ridged bead 7 is also formed in the longitudinal direction of the inclined insertion portion 3. These beads 7 increase the mechanical strength of the vertical insertion portion 2 and the inclined insertion portion 3. This is because the quenching process is omitted in the manufacturing process of the fixture 1 according to the present invention. The projecting direction of the ridge of the bead 7 may be either outside or inside, but it is preferable to perform beading (pulling) at the same time as cutting, so that the number of working steps is not increased.

The inner supporting portion 5 has a cross section continuous from the upper portion of the inclined insertion portion 3 toward the vertical insertion portion 2 so that the interval between the vertical insertion portion 2 of the insertion portion 4 and the inclined insertion portion 3 is not narrowed. Is bent so as to have a substantially rectangular shape. A rounded folded portion 8 is formed at the tip edge of the inner support portion 5 so as to easily slide on the inner surface of the inclined insertion portion 3. Further, a bead 7 for increasing the mechanical strength is formed also at the tip portion and the bent portion of the inner support portion 5.
In addition, the projecting direction of the ridge of the bead 7 formed on the inner supporting portion 5 may be either the outside or the inside.

The retaining portion 6 is formed so as to continuously protrude from the upper portion of the vertical insertion portion 2 to the side in a substantially vertical direction with respect to the vertical insertion portion 2. This retaining part 6
The groove 10 of the support 9 and the sound insulation panel 11 will be described later.
Has a function of preventing slipping when the brackets 17 and 20 are inserted into the gaps between them and the brackets 17 and 20 on the support column 9 side and the sound insulation panel 11 side. The retaining portion 6 has a wire insertion hole 1.
2 is drilled. When the sound insulation panel 11 is attached to the support 9, the wire insertion hole 12 is used to insert a wire (not shown) through the wire insertion hole 12 so that the fixing bracket 1 is inserted.
To prevent the device from dropping during installation work or repair and replacement work.

As described above, the fixture 1 having the beads 7, 7 formed in the longitudinal direction of the vertical insertion portion 2 or the inclined insertion portion 3.
Has increased mechanical strength. Tables 1 and 2 below show the amount of deflection with respect to the load between the fixing bracket (Table 1) having no beads and the fixing bracket 1 having the beads 7, 7 formed on the vertical insertion portion 2 or the inclined insertion portion 3. (Table 2). This "flexure amount" indicates the elasticity when the fixing fitting 1 is fixed in the gap between the edge 11a of the sound insulation panel 11 and the concave groove 10 of the support post 9, and in this experiment, the flexure amount was 50 mm. A load is applied to both sides of the vertical insertion part 2 or the inclined insertion part 3 of the fixing bracket 1 at that time, and either the vertical insertion part 2 or the inclined insertion part 3,
Or, they tested whether both did not break. As is clear from Tables 1 and 2, the fixture without the bead could withstand only a load of about 100 kg, but the fixture 1 with the beads 7, 7 according to the present invention.
Can withstand a load of about 200 kg, and the mechanical strength is about doubled.
