Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal fitting for fixing an end portion of a plate material such as a plastic light-transmitting plate on a soundproof wall of a highway or the like to a column having an H-shaped cross section or the like.

[0002]

2. Description of the Related Art On a highway close to a house, it is common to provide a soundproof wall along a road side. The soundproof wall is provided with a support having an H-shaped cross section at predetermined intervals along the roadside, a metal soundproof plate having a wavy cross section is stretched between the supports, and a light transmissive plate made of plastic such as acrylic is provided at the upper part. It is composed by stretching. The use of an acrylic translucent plate in the upper part is due to the sunshine, view and beauty.

Conventionally, as shown in FIG. 1, an acrylic translucent plate 102 with respect to a support 100 forming an H-shaped channel is used.
Was fixed using a tapered fixing bracket 104. The bolt 106 is connected to the bolt hole 108 of the fixing bracket 104 and the center wall.
The fixture 104 is fastened to the center wall 100A by inserting it into the 100A bolt hole 110 and screwing it into the nut 112. As shown in FIG. 1, the fixing bracket 104 has a tapered surface 104A.
The fixing bracket 104 is laterally displaced toward the channel side wall 100B by the wedge action of the tapered surface 104A, and the acrylic translucent plate 102 is pressed against the side wall 100B to fix the acrylic translucent plate 102 to the column 100. Can be.
Note that the fixing bracket 104 has a stay 104B for reinforcement.

[0004]

In the prior art, the acrylic translucent is caused by some lateral displacement of the fixture 104 to the side wall 100B under wedge action when the fixture 104 is fastened to the central wall 100A by bolts 106. Plate 102 on side wall 100B
Had been pressed. As described above, the acrylic light-transmitting plate 1 is moved while the fixing bracket 104 is laterally moved when the bolt 106 is fastened.
02 is pressed against the side wall 100B, there is a slight misalignment between the bolt hole 108 of the fixing bracket 104 and the bolt hole 110 of the support center wall 100A before the tightening in accordance with the amount of lateral movement. The bolt holes 108 and 110 are formed relatively large in order to allow the bolt 106 to be inserted between the fixing bracket 104 and the support center wall 100A regardless of such misalignment. Further, a bolt having a large length was used. Even so, the bolt holes 108 and 110 are misaligned before the bolts are inserted, so the bolt 10
6 was difficult to insert and the workability was extremely poor. In addition, it is not possible to cope with variations in the width of the channel, and it is also impossible to securely fix the acrylic translucent plate, and it is necessary to add an auxiliary plate such as a spacer.

Further, in the prior art, the fixing bracket 104 is used.
Is introduced into the channel width of the H-shaped support and presses the acrylic light-transmitting plate against the side wall by a lateral wedge action, so that the fixing bracket 104 needs to have a width almost equal to the entire width of the channel. There was a drawback that the dimensions were large and the weight had to be large. In addition, there is a problem that a fixing bracket corresponding to the channel width of the column is required, and the types thereof are increased.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a plate end fixing metal which can easily be fastened, can be reduced in size, and can reduce the number of types.

[0007]

According to a first aspect of the present invention, an end of a plate is fixed to a column having a first wall surface and a second wall surface extending in a direction crossing the first wall surface. In the plate material end fixing bracket for fixing, the first material is fixed before the plate material is fixed.
The end facing the second wall is separated from the second wall by bending in a direction away from the second wall, but is flattened by being bolted to the first wall, and the second wall is flattened. The end of the sheet material is displaced in the direction toward the second wall surface, thereby fixing the end of the sheet material to the column.

According to the second invention, a plate made of a plastic light-transmitting material is stretched between the columns each having the first wall surface and the second wall surface extending in a direction crossing the first wall surface. A plate end fixing metal used for a soundproof wall in which an end of the plate is fixed to a pillar, wherein the second wall is bent in a direction away from the first wall before fixing the plate. The end facing the second wall is separated from the second wall, but is flattened by being bolted to the first wall, and the end facing the second wall faces in the direction toward the second wall. A plate end fixing metal is provided which is displaced, thereby fixing the end of the plate to the column.

[0009] Preferably, the column has a U-shaped channel such as an H-shaped cross section, the first wall surface is a channel bottom surface, and the second wall surface is one of opposed channel side surfaces.

According to the present invention, the fixing bracket is flattened when the bolt is fastened to the first wall surface, so that its end is displaced laterally to the second wall surface. The end of the plate is fixed to the column.
Therefore, as long as the bolting position with respect to the first wall surface is set to a position where a stroke necessary for fixing the end of the plate material to the second wall surface by flattening the fixing plate can be obtained, the H-shaped steel constituting the column can be formed. Regardless of the change in the size (the interval between the side walls), the end of the plate material can be fixed by the fixing bracket of the same size. Therefore, it is not necessary to prepare a fixing bracket for each size of the H-shaped steel, so that the size can be reduced and the number of types of press dies can be reduced, so that the manufacturing cost can be reduced.
In addition, it can be fixed regardless of variation.

Further, in the bent state of the fixing plate, there is no problem in assembling the soundproof wall even when the fixed plate is attached to the column, and the workability can be improved. That is, when the end of the plate is introduced, the end of the fixing bracket can be retracted and positioned, so that there is no obstacle to the preparation work such as insertion of the plate, and the flattening is performed only by fastening the bolt, and the end of the fixing bracket is fixed. Is displaced toward the support, and the end of the plate is pressed against the opposing wall,
The work of fixing the plate material to the column is completed, and workability can be significantly improved.

The fixing bracket can be bent in a mountain shape in a direction away from the first wall surface. The fixing plate is flattened by being pressed, and the fixing plate is flattened in the flattening direction at the time of pressing. A pressure plate attached to one end, wherein the fixing plate is bolted to the first wall surface, while the pressure plate is opposed to the second wall surface with the plate material interposed therebetween, and the pressing plate is fixed by a pressing force when fastening the bolt. Is flattened, thereby displacing the pressing plate toward the second wall surface, thereby fixing the plate member to the column. With this configuration, it is possible to more efficiently transmit the lateral extension displacement of the fixing bracket during flattening to the plate material.

The fixing plate is mounted on a first wall surface and has a bolt inserted therein. The fixing plate is rotatably connected at one end to the fixing portion, and the pressure plate is attached to the other free end. The movable portion may be bent in a mountain shape in a direction away from the first wall surface before the plate member is fixed, and may be rotated at one end in a direction away from the fixed portion. With this configuration, at the time of bolt fastening, the movable portion is rotated at one end with respect to the fixed portion, the angled cross section of the movable portion is flattened, and the movable portion is relatively large with respect to the pressing plate attached to the free other end of the movable portion. Can have a stroke.

The one end of the movable part can be integrally connected to a fixed plate. In this case, the rotation of the movable portion with respect to the fixed portion during the fixing operation of the plate material is elastically or plastically deformed at the integrated connection portion. This configuration has the advantage that the fixed part and the movable part are integrated, and the number of parts is reduced.

In order to rotatably connect the one end of the movable portion to the fixed plate, a rotating means comprising a pin and a pin hole can be provided. Further, the movable part rotates a first movable member rotatably connected to the fixed part, a second movable member having a pressure plate attached thereto, and a first movable member and a second movable member. It can be constituted by a pivoting means comprising a pin and a pin hole which are connected as much as possible. In this case, even after the fixing bracket is used once for fixing the plate material, there is no possibility that the respective parts constituting the fixing bracket are permanently deformed.
The fixing bracket can be reused. In the above, it is possible to provide a spring means for urging the movable part to rotate around the center of the pin in a direction away from the fixed part in a normal state, and further comprising a first movable member and a second movable member. And spring means for biasing the pin to rotate around the center of the pin so that the two have a mountain shape.
Thus, when not in use, the fixing metal can always have a fixed shape separated from the wall surface facing the pressure plate, and the workability when setting the fixing metal on the support can be enhanced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS.
Numeral 0 is provided on the road side of the highway, and is provided upright at a predetermined interval, and has an upper end slightly curved toward the center of the road (FIG. 3) and a support 1 at the lower part of the protective wall.
A soundproof plate 14 which is stretched between two and is formed of steel material, and is stretched between the struts 12 in the upper part of the protective wall in two upper and lower stages,
It is composed of a light-transmitting plate 16 made of plastic such as acrylic, and a beam 18 between the upper and lower light-transmitting plates 16. The upper light-transmitting plate 16 has an upper end 16 'slightly protruding from the upper end of the column 12, and is somewhat bent toward the road surface (FIG. 3).

As shown in FIG. 4, the column 12 is a central wall 12-1.
(It becomes the first wall surface of the present invention) and a side wall 12-2 extending on both sides in a direction orthogonal to both ends thereof (a side of the pair of side walls 12-2 facing the light transmitting plate 16 is a second wall surface of the present invention). (A wall surface). That is, the channel 20 having a U-shaped cross section extends vertically back to back with the center wall 12-1 interposed therebetween. The support center wall 12-1 is arranged in a direction orthogonal to the road side. In other words, each channel 20 of one support 12 is open to the adjacent support 12.

According to the fixture of the present invention, as will be apparent from the following description, not only a column having a U-shaped cross section but with a U-shaped cross-section back to back, but also a mere U-shaped cross section. The light-transmitting plate can be fixed to a support, and further to a support having an L-section.

Each end of each translucent plate 16 extends to a channel 20 as shown in FIG. As shown in FIG. 3, the lower light-transmitting plate 16 is fixed at one end to the column 12 by three fixing brackets 24, and the upper light-transmitting plate 16 is attached to the column 12 by four fixing brackets 24 at one end. ing.

Next, the fixing structure of the light transmitting plate 16 by the fixing metal 24 will be described. The fixing metal 24 includes a fixing plate 25 bolted to the central wall 12-1 and the light transmitting plate 16 to the side wall 12-2. And a pressure plate 26 for pressing toward the surface. The fixing plate 25 is a flat fixing portion 2 placed on the central wall 12-1.
7 and a movable portion 28 having a chevron-shaped cross section and extending integrally from one end of the fixed portion 27. That is, the hinge connecting portion 29 connecting the fixed portion 27 and the movable portion 28 functions as an integral hinge, and the fixed portion 27 and the movable portion 28
The hinge 9 can be opened and closed hingedly by its elasticity. The movable portion 28 has a mountain shape in cross section. The top of the mountain shape is crushed when pressure is applied by a bolt 30, and the metal fitting is shown in FIG. 5 in combination with the hinge connection portion 29 as an integral hinge. Such a whole can be in a state of being crushed flat.

The fixed portion 27 and the movable portion 28 form bolt holes 27-1 and 28-1 which are vertically aligned, respectively, and the bolt 30 is inserted into these bolt holes 27-1 and 28-1. By fastening to the nut 35 via the central wall 12-1, the fixing plate 25 can be deformed against its elasticity from a bent state as shown in FIG. 4 to a flat crushed state as shown in FIG. It has become. The movable portion 28 has side walls 31 on both sides thereof (see FIGS. 7 and 8). On this side wall 31, a slit 31-1 extends from the vicinity of the peak of the chevron to the lower end surface. A leg 32 is formed. When the pair of support legs 32 are not fastened, they are separated from the center wall 12-1 as shown in FIGS. 4 and 7, but in the fastened state of FIGS. 5 and 8, the support legs 32 abut the center wall 12-1. Thus, the movable portion 28 is prevented from being further deformed, that is, the fastening force is prevented from being reduced, and a predetermined fastening force can always be obtained.

Next, a description will be given of the pivotal attachment structure of the pressing plate 26. A pair of ears 26-1 are formed on the surface of the pressing plate 26 facing the fixed plate 25 (FIG. 7). Part 26
-1 extends toward the fixing plate 25. On the other hand, the movable part 2
A pair of ears 31-1 extend integrally from the side wall 31 of the pair.
The pin 33 is rotatably inserted into the ear portions 26-1, 31-1. As a result, the pressing plate 26 is rotatable about the pin 33 with respect to the fixed plate 25.

The pressing plate 26 is slightly raised from the center wall 12-1, and a holding plate 34 is located below the raised pressing plate 26 (FIGS. 4 and 5). Presser plate 3
Reference numeral 4 has an L-shaped cross section, and functions to transmit the tightening force from the fixing bracket 24 during the tightening operation to the light transmitting plate 16 via the gasket 36. As shown in FIGS. 3 and 6, the holding plate 34 is fixed to the central wall 12-1 by bolts 38 and nuts 40 at portions not interfering with the fixing bracket 24. As will be described later, the holding plate 3 in which the tightening force is in the temporarily tightened state at the time of tightening the fixing bracket 24 by flattening.
4 and transmitted to the light transmitting plate 16 via the gasket 36,
The light-transmitting plate 16 is fastened and held to the side wall 12-2. In order to secure some lateral movement of the holding plate 34 during this fastening operation, a hole 34- of the holding plate 34 through which the bolt 38 is passed. 1 is a large hole or a long hole.

Next, the operation of mounting the light transmitting plate 16 by the fixing bracket 24 of the present invention will be described. The pressing plate 34 is introduced into the channel 20 and the bolt 38 and the nut 4
With 0, it is temporarily fixed to the support center wall 12-1. When the holding plate 34 is temporarily fixed, the tightening of the bolts 38 and the nuts 40 is slightly smaller than the original tightening force. When a lateral tightening force exceeding the temporary tightening force is applied by the fixture 24, the holding plate 34 is tightened. Can move sideways toward the support side wall 12-2. Also, in this temporarily fixed state of the holding plate 34, the space between the holding plate 34 and the support side wall 12-2 (the light transmitting plate insertion groove) is such that the light transmitting plate 16 and the gasket 36 can be inserted with a sufficient margin. As shown in FIG. 6, the bolt 38 is inserted through the pair of holding plates 34 with the center wall 12-1 interposed therebetween. That is, as with the fixture 24, a pair of bolts 38 and nuts 40 are commonly used for the pressing plates 34 adjacent to each other with one column 12 interposed therebetween.

Next, the fixing bracket 24 is attached to a predetermined position (seven positions in FIG. 3) of the column 12 by means of bolts 30 and nuts 35, respectively. At this time, the bolt 30 and the nut 35 are in a completely loosened state, the fixing plate 25 is in a bent state as shown in FIGS. 4 and 7, and the metal fitting 24 is not separated from the support 12 but is in a free state. Has become. Therefore, the pressing plate 26 is located at the position farthest from the side wall 12-2. Further, as shown in FIG. 4, the bolt 30 is inserted through the pair of fixing brackets 24 with the support center wall 12-1 interposed therebetween.
That is, a pair of light transmitting plates 1 adjacent to each other with one support 12 interposed therebetween.
A pair of bolts 30 and nuts 35 are also used for a pair of fixing fittings 24 for fixing the fixing member 6.

Next, a light-transmitting plate 16 is introduced between the opposing columns 12. That is, the light-transmitting plate 16 has the gasket 36 interposed at its end, and the pressing plate 34 and the support side wall.
It is inserted from the gap between 12-2. As aforementioned,
In the temporarily fixed state of the holding plate 34, the holding plate 34 and the support side wall 12-2
Between the light transmitting plate 16 and the gasket 36.
Can be inserted with a margin.

Next, when the bolts 30 and the nuts 35 are tightened in the fixture 24 in the bent state as shown in FIG. 4, the bolts 30 or the nuts 35 come into contact with the movable portion 28 at the apexes of the chevron. As the bolts 30 and the nuts 35 are tightened, the angle of the chevron of the movable portion 28 becomes closer to horizontal. Fixed part 27 at hinge connection part 29
The elastic connection of the movable part 28 with respect to assists the deformation of the movable part 28 at the chevron. As the Yamagata is flattened,
The free end of the movable portion 28, in other words, the pressing plate 26 attached to the free end is displaced toward the side wall 12-2. The pressing plate 26 is placed on the holding plate 34 and the pressing plate 2
6 is pivotally attached to the movable portion 28, and as the flattening progresses, the pressing plate 26 placed on the holding plate 34 keeps the side wall 12-2 facing the side wall 12-2. Sliding displacement in the direction toward -2.

As the fastening by the bolt 30 and the nut 35 is continued, the pressing plate 26 comes into contact with the holding plate 34 and overcomes the fastening force of the temporarily tightened bolt 38 and the nut 40, and the holding plate 34 is moved to the side wall 12. Displacement toward -2.
The diameter of the bolt hole 34-1 of the holding plate 34 is selected to be large or long so as to allow such lateral movement of the holding plate 34 (see FIG. 6). The lateral movement of the holding plate 34 causes the light transmitting plate 16 to be displaced toward the side wall 12-2 via the gasket 36, and the light transmitting plate 16 is moved via the gasket 36 to the pressing plate 3
4 and the side wall 12-2. As the fastening of the bolts 30 and the nuts 35 is advanced, the support legs 32 eventually come into contact with the central wall 12-1 (FIGS. 5 and 8), and the bolts 30 and the nuts 35 cannot be further fastened. At this time, the light transmitting plate 16 is sandwiched and held between the pressing plate 34 and the side wall 12-2 via the gasket 36 with a predetermined fastening force. The provision of the support legs 32 prevents the bolts 30 and the nuts 35 from being excessively tightened to a position where the maximum tightening force can be obtained, and the fixing plate 25 becomes flat. By simply tightening up to the position where the support legs hit, it is possible to always ensure the specified tightening force without requiring the operator to work together, and to improve the work efficiency when assembling the protective wall. There is an effect that can be increased.

In this manner, at the angular position where the desired fastening force is obtained, the bolt 30 and the nut 35 are fully tightened, and thereafter, the bolt 38 and the nut 40 for fixing the holding plate 34 to the central wall 12-1. The final tightening is also performed.

The fixing bracket 24 of this embodiment can fix the light-transmitting plate 16 by using fixing brackets having the same dimensions irrespective of the size of the H-shaped steel constituting the column 12. That is, even if the fixing metal 24 is located at the position of the support center wall 12-1 at which a lateral displacement (stroke) is obtained by the flattening of the fixing metal 24 and the required tightening force of the light transmitting plate 16 by the pressing plate 26 is obtained. For example, when the bolts and nuts are fastened, the fastening action of the light-transmitting plate 16 by the fixture 24 can be obtained irrespective of the size of the H-section steel, that is, the dimension between the side walls 12-2. for that reason,
It is not necessary to prepare the fixing bracket 24 for each size of the H-shaped steel.
By sharing the same 4, it is possible to reduce the size and weight and to reduce the manufacturing cost because the press die for manufacturing the fixing bracket is shared.

Further, even when the fixing bracket 24 is attached to the column 12, there is no problem in assembling the soundproof wall, and the workability can be improved. That is, even if the fixing bracket 24 is attached to the H-shaped steel, if the fixing bracket 24 is bent by loosening the bolts 30 and the nuts 35, the plastic translucent plate 16 and the holding plate 34 can be formed. It can be evacuated so as not to interfere with the mounting work. Therefore, the work required at the time of fastening the light transmitting plate 16 is only the work of fastening the bolt 30 and the nut 35 until the support leg 32 comes into contact with the central wall 12-1 in order to flatten the fixing bracket 24. , Workability can be improved. In the conventional structure (FIG. 1), it is not possible to attach the fixing bracket 104 to the column 100 before setting the fixing bracket 104 in advance, and it is necessary to attach the fixing bracket 104 to the column at a high place when the translucent plate 102 is fastened. As described at the beginning of the book, there was a problem that the bolting property was poor and the workability was extremely poor, but the present invention can improve this point.

Further, according to the present invention, since the support leg 32 is provided, after the support leg 32 hits the center wall 12-1, further tightening cannot be performed. Conversely, the fastening is continued until the support leg 32 hits. A predetermined fastening force can be reliably obtained only by performing the operation, and there is an effect that the workability can be improved and the physical labor can be reduced.

In the first embodiment shown in FIGS. 1 to 8, flattening of the fixture is performed by an integral hinge connection. Therefore, permanent deformation is applied after use, and the fixing bracket cannot be reused. FIGS. 9 to 14 show a second embodiment which solves this point. In the second embodiment, a hinge fitting portion composed of a pin and a pin hole enables reuse of a fixing bracket. is there. That is, in the second embodiment, the fixing bracket 24 is composed of the fixing plate 25 and the pressing plate 26, and the fixing plate 25 is composed of the fixing portion 27 and the movable portion 28 in FIGS. This is similar to the first embodiment. However, unlike the integrated structure in the first embodiment, in this embodiment, the first movable member 50 is connected to the fixed portion 27 by a hinge means (joint) 54 including a pin and a pin hole, and the first movable member 50 is connected to the fixed portion 27. 50
Is connected to the second movable member 52 by a hinge means (joint) 56 also composed of a pin and a pin hole.

Next, the structure of the hinge means 54, 56 will be described in more detail. As shown in FIG. 11, the fixed part 27 has a cylindrical winding part 58 at one end, while the first movable member 50 has a cylindrical winding part 60 sandwiching the cylindrical winding part 58, and a pin hole 61 aligned with the cylindrical winding part 58, 60 is formed. A pin 62 is provided, and the pin hole 61 and the pin 62 are
A hinge means 54 for rotating the first movable member 50 around the center of the pin with respect to 7 is formed. Also, the first movable member 5
0 forms a pair of ears 64 at the end facing the cylindrical winding part 58, while the second movable member 52 also forms a pair of ears 66 at the end facing the pressure plate 26. The pair of ears 66 is inserted between the pair of ears 64, and the ears 64 and 66 form a pin hole 68 aligned with the center, and the pin 70 is inserted through the pin hole 68. And
The pin hole 68 and the pin 70 constitute hinge means 56 for bending the first movable member 50 and the second movable member 52 mutually. The pins 62 and 70 have a simple round bar shape at the time of insertion at the time of assembling, but after insertion, the ends 62a and 70a are crushed, thereby preventing the pins 62 and 70 from coming off.

In FIG. 9, the spring 72 is
One end 72a extending from the cylindrical portion inserted into the fixing portion 2
7, the other end 72b is engaged with the first movable member 50, whereby the spring 72 is elasticized, and the first rotating member 50 is rotated in a direction away from the fixed portion 27 (clockwise direction in FIG. 9). It is something that I tried. Also, the spring 76
Engages one end 76a extending from the cylindrical portion inserted into the pin 70 with the first movable member 50 and the other end 76b with the second movable member 52, thereby making the spring 76 elastic,
And the second movable members 50 and 52 are normally bent into a mountain shape as shown in FIG. 9 in a normal state. 9, a stopper 7 is provided on the bottom surface of the first movable member 50.
7 are provided integrally to prevent the first and second movable members 50 and 52 from bending more than illustrated. A stopper 79 is provided on the lower surface of the second movable member 52, and when the side of the pressing plate 26 engages with the stopper 79, the pressing plate 26 is prevented from rotating further with respect to the second movable member.

The first movable member 50 and the second movable member 52 have legs 80, 82 formed on the bottom surface thereof, respectively, and these legs 80, 82 are attached to the support columns by the fixing brackets as in the first embodiment. Engage with the support center wall 12-1 when fixing the translucent plate,
The fixing bracket always fixes the translucent plate with a constant force,
It is possible to avoid the possibility that the fastening force is reduced due to excessive closing.

The operation of fixing the light-transmitting plate to the column by the fixing fitting of the second embodiment is the same as that of the first embodiment. Prior to attachment to the column, the fixture is bent by the springs 72 and 76 as shown in FIG. Therefore, in this state, by temporarily fixing the fixing bracket to the center wall 12-1 of the column with the bolt 30, a groove for inserting the end of the light transmitting plate is formed between the pressing plate 26 and the holding plate 34. It is formed. After that, the end of the light-transmitting plate is inserted into this groove, and the fixing bracket is flattened by tightening the bolt 30 to displace the pressing plate 26 toward the side wall of the support. The portion is sandwiched between the pressing plate 26 and the holding plate 34. The operation at this point is the same as in the first embodiment.

In the second embodiment, the spring
It is not necessary to provide 72 and 76. Spring 72, 76
When there is no bolt, it is necessary to manually bend the fixing bracket so that the pressing plate 26 retreats before inserting the translucent plate, but the operation after fastening the bolt 30 is the same.
