[0004]
In order to construct the soundproof wall with the cap material of the structure of FIG. 13 and FIG. 14, after each column 2 is erected at a required position, the soundproof panels 3 are sequentially stacked from the lowest order along the vertical direction, and each time the soundproof panels 3 are stacked. The soundproof panel 3 is fixed to the corresponding column 2.
After fixing the end of the uppermost soundproof panel 3 to the corresponding support 2, the cap material 3a is fixed to the upper part of the uppermost soundproof panel 3 so as to cover the upper part.
[0005]
As shown in FIG. 14, the cap material 3a includes outer plates 3b, 3b formed of symmetrical hook-shaped perforated plates, inner plates 3c, 3c each having a shape similar to the outer plate 3b and a smaller size, and each outer plate 3b. , 3c and glass wool and other sound absorbing materials 3d, 3d installed in an inserted manner. Therefore, the cap material 3a is formed in a substantially pot-shaped cross section in which the front side and the back side in the upper part bulge in an arc shape.
The outer plates 3b, 3b and the inner plates 3c, 3c are connected to each other via an upper connecting plate 3e.
The soundproof panel 3 includes a front plate 30 made of a perforated plate having holes formed in a louver shape, a rear plate 31 parallel to the front plate 30 via a predetermined space, and spacers for the front and rear plates 30, 31. The upper plate 32 also serves as a bottom plate and side plates (not shown), and glass wool and other sound absorbing materials (not shown) inserted therein.
In order to fix the cap material 3a to the upper part of the uppermost soundproof panel 3, the fixing plates 3f, 3f are fixed to the inside of the end hanging parts of the inner plates 3c, 3c along the length direction by screws, respectively. The mounting plates 3f, 3f are mounted on the front plate 30 and the rear plate 31 of the soundproof panel 3 with bolts and nuts 33, 33, respectively.
[0006]

[0023]
As shown in FIGS. 5 and 6, first, on the upper part of the shoulder wall 10 of the highway 1, the support columns 2 made of H-shaped steel are erected by a suitable anchor member 11 or the like so as to be upright at substantially constant intervals. In this upright state, the side surfaces of the flanges 20, 20 (FIGS. 4, 7 and 8) of the column 2 face the front side and the back side, which are the sound source side.
Between each of the columns 2, soundproof panels 4a, 4a, 4a of a predetermined unified standard are installed in a crosswise manner and in a state of being vertically overlapped, and both ends of each of the soundproof panels 4a are respectively arranged. It is fixed to the support 2 in order. In this embodiment, the height of the soundproof wall to be constructed is 2 m, and therefore, the height of each soundproof panel 4a, 4 is 500 mm.
After that, the soundproof panel 4 of the above-described embodiment is similarly set on the uppermost position, and its end is fixed to the adjacent columns 2 and 2.
[0024]
Each lower soundproof panel 4a removes the cap member 5 and the reinforcing plate 48 from the uppermost soundproof panel 4, forms a hole 40a up to the upper part of the front plate 40, and until it reaches the upper part of the back surface of the front plate 40. This is the same structure as that in which the sound absorbing material 45 is installed.
Each of the soundproof panels 4a, 4 is installed in such a manner as to guide both ends thereof between the pair of flanges 20, 20 of the column 2, as shown in FIG. A rope or a wire (not shown) is passed through a portion of the eyebolt 47 on the side, and the rope is lifted by, for example, a mobile crane and moved to an appropriate position, and the end of each of the soundproof panels 4a, 4 is connected to the flanges 20, 20 of the column 2. I will guide you in the meantime.
[0025]
A hole 22 is formed in a web portion 21 near the lower end of each column 2, and a wire 21 is passed through the hole 22 as shown in FIG.
Each time the soundproof panels 4a, 4 are stacked in sequence, the wire 23 is passed through an eyebolt 47 on the side of the panels 4a, 4, and at the side end of the panels 4a, 4 as shown in FIGS. Then, the holding member 6 is pushed into the gap c between the rear surfaces of the soundproof panels 4a, 4 and the flange 20 on the back side of the support 2 (punching), and both ends of the soundproof panels 4a, 4 are fixed to the supports 2,2.
As shown in FIG. 8, the holding member 6 is composed of a plate-shaped holding member 60 and an elastic pressing member 61 integrated with the holding member 60. The holding member 60 is provided on the upper surface of the end of the soundproof panels 4a, 4. The soundproof panels 4a, 4 are fixed to the support columns 2 by pushing or driving the elastic pushing pieces 61 into the gap c from above until they come into contact.
[0026]
As shown in FIGS. 7 and 8, a lid-shaped locking plate 25 is fixed to the upper end of each column 2 via angle fittings 24, 24, and the locking plate 25 is attached to the soundproof panel 4 in the length direction. A long hole-like insertion hole 27 is formed along the hole.
If the lowermost soundproof panel 4a is fixed in order from the lowest soundproof panel 4a to the highest soundproof panel 4 between the columns 2 as described above, the upper end of each wire 23 as shown in FIGS. Is inserted from below into the insertion hole 27 of the locking plate 25 at the upper end of each column 2, and the wires 23 are tightened by the tightening screws 26.
With this construction, the uppermost soundproof panel 4 which is stacked in the vertical direction and fixed to each support 2 and each lower soundproof panel 4a are linked so as not to shift.
[0027]
Next, the vacant portion between the adjacent cap members 5 (the portion corresponding to the upper part of the support column 2) has an inverted channel shape in the cap members 5 so as to overlap the mutual connecting plates 50a, 50a. An auxiliary cap member 56 having a cross-sectional shape substantially matching the cross-sectional shape of the main part of the panel member 50 is covered and covered, and the auxiliary cap member 56 is connected to the connecting plates 50a, 50a on both sides by rivets, bonding, or other means.
By performing the construction as described above, the soundproof wall having the continuous cap material 5 so as to surround the upper end is constructed.
As shown in FIG. 8, the auxiliary shade member 56 in this embodiment includes a front panel 51 a and a rear panel 52 b having the same cross-sectional shape as the front and rear panels 51 and 52 of the inverted channel panel member 50. In the two panels 51a and 52a, the overlapping portions of the divided portions are connected in advance by rivets.
[0028]
When the construction for replacing the cap material 5 is performed, each auxiliary cap material 56 is removed, the fastening screw 26 is removed, the wire 23 is removed from the eyebolt 47 of the uppermost soundproof panel 4, and the presser fitting 6 is removed.
Then, the soundproof panel 4 is removed together with the cap member 5 through a rope or the like (not shown) to the eyebolt 47 of the uppermost soundproof panel 4, and the new soundproof panel 4 with the cap member is stacked on the lower soundproof panel 4a. The construction may be performed in the same manner as in the embodiment.
[0029]
According to the soundproof wall constructed as described above, the sound wave of the noise generated on the front side a of FIGS. 1 and 6 passes through the front plate 40 of each soundproof panel 4, 4 a and is reduced by the sound absorbing material 45. Then, the light passes through the space 4b on the back surface of the sound absorbing material 45, is reflected by the back plate 41, and is further reduced by passing through the sound absorbing material 45 again.
The sound wave reaching the front side of the cap member 5 from the sound source is reduced by the sound absorbing material 53 while moving to the rear side along the surface of the arc-shaped upper plate portion 5a and lower surface plate portion 5b. The sound is reflected by the portion protruding into the cap material 5 and the sound insulating plate 54, and is further reduced by passing through the sound absorbing material 53 again.
[0030]
The soundproof wall using the soundproof wall panel 4 with the cap material of the embodiment.According to the above, the cap material 5 is attached to the uppermost soundproof panel 4 in advance so as to cover the upper part thereof, and the cap material 5 is superimposed on the lower soundproof panel 4a and fixed to the column 2, so that the uppermost soundproof panel 4 is fixed. There is no need to install a scaffold on the back side b for attaching the cap material 5 to the support 4 or the support 2, and the soundproof wall with the cap material can be constructed at a very low cost.
thisNoise barrierAccording to the present invention, the cap member 5 is attached to a portion of the uppermost soundproof panel 4 except for a portion guided between the flanges 20 of the column 2, and a portion corresponding to the upper portion of the column 2. Are connected to the ends of the cap material 5 of the uppermost soundproof panel 4 on both sides sandwiching the support column 2, and have an auxiliary cap material 56 having a cross-sectional shape substantially matching the cross-sectional shape of the main part of the cap material 5. Therefore, it is very smooth to fix the uppermost soundproof panel 4 to the support column 2 by the holding metal 6.
[0031]
According to the soundproof panel with the cap material of the above embodiment, the soundproof panel with the cap material 4 is superimposed on the lower soundproof panel 4a immediately below, excluding the uppermost soundproof panel, at the time of construction, and this is fixed to the column 2. In addition, the construction method of the soundproof wall can be smoothly performed.
In the soundproof panel with a capping material of this embodiment, the capping material 5 is attached to the upper part of the soundproofing panel 4 of a predetermined standard so that the upper part of the soundproofing panel 4 partially enters. Is not so high, the load on the support column 2 is reduced by that much, and the visibility can be further reduced.
In the soundproofing panel with the cap member, the portion facing the upper portion of the cap member 5 forms the upper surface plate portion 5a having an arc-shaped cross section, so that sound waves from the sound source side are transmitted to the rear side along the upper surface plate portion 5a. The light is diffracted smoothly, and the sound is smoothly reduced inside the cap material 5 in the process.
In the soundproof panel with the cap material, a sound insulating plate 54 is provided inside the cap material 5, and the sound wave during the diffraction is reduced by the sound absorbing material 53 through the inside, passes through the space, and passes through the space. And is again reduced by the sound absorbing material 53, so that a greater noise reduction effect can be obtained.
In the soundproof panel with a cap member, the channel-shaped reinforcing plate 48 is inserted in a spacer shape inside a portion of the cap member 5 to which the inverted channel-shaped panel member 50 is fixed. When 5e and 5f are attached to the soundproof panel 4 with rivets or screws, the soundproof panel 4 can be prevented from being weakened or deformed.
Since the inverted channel-shaped panel member 50 is divided into the front panel 51 and the rear panel 52, the soundproof panel with the cap member is very easy to form, for example, during extrusion molding. By simultaneously connecting one end of the sound insulating plate 54 to the joining portion (connecting portion) of the above, it becomes very easy to attach the sound insulating plate 54 inside the cap material 5.
In the soundproof panel with the cap material, both ends of the soundproof panel 4 protrude from the both ends in the longitudinal direction of the cap material 5 by a predetermined amount. It is smoother to guide the end and fix the end to the column 2 with the holding metal 6 or the like.
In the soundproof panel with the cap member, a connecting plate having substantially the same cross-sectional shape as the inverted channel-shaped panel member 50 is provided at an end of the inverted channel-shaped panel member 50 in a state of partially overlapping the inside of the panel member 50. Since they are connected, the construction in which the adjacent cap members 5 are connected to each other via the auxiliary cap members 56 is performed smoothly.
[0032]
In the embodiment, the front panel 51 and the rear panel 52 can be formed to have the same cross-sectional shape and the same size. By molding in this manner, the panel can be used as both panels 51 and 52 by manufacturing only one type.
[0033]

[0034]
In the soundproof panel with a cap member according to this embodiment, the soundproof panel 4 is configured substantially in the same manner as the first embodiment, but the apparent thickness is thicker than the soundproof panel of the first embodiment, and the space 4b is wider by that amount. The point that many holes 40a of the front plate 40 are not louver-shaped but round holes, the point that the top plate 42 is integral with the back plate 41, and both sides of the soundproof panel 4 are vertically The difference is that a notch portion 49 is formed along which a part of the column 2 is guided.
The cap member 5 has a point that the front side panel 51 and the rear side 52 of the inverted channel-shaped panel member 50 have substantially the same shape and size, and as shown in FIG. This is different from the soundproof panel of the first embodiment in that the length of the soundproof panel 4 is the same as that of the soundproof panel 4 and that the connecting plates are not provided at both ends of the inverted channel-shaped panel member 50.
Other configurations are almost the same as those of the soundproof panel with the cap material in the first embodiment, and thus description thereof is omitted.
[0035]

In this embodiment, the front side flanges 20 of the strut 2 having the H-shaped cross section form the smooth portion 20a. are doing. The column 2 need not have an H-shaped cross section as long as the smooth portion 20a is formed facing the front side, and may have a rectangular pipe cross section, a channel shape, or another cross section shape.
[0036]
Lower soundproof panels 4a are sequentially stacked between adjacent columns 2 in a vertically extending manner, and their ends are fixed to the columns 2.
The configuration of the lower soundproof panel 4a other than the uppermost soundproof panel 4 is almost the same as that of the uppermost soundproof panel 4, except that the cap member 5 is not attached and the sound absorbing material 53 is formed of the front plate 40. The soundproof panel 4 is different in configuration from the soundproof panel 4 in that the hole 40a is formed up to the upper end of the front plate 40 and that the reinforcing plate 48 is not provided.
After each soundproof panel 4a is fixed to the column 2, the soundproof panel 4 having the cap material 5 is superimposed on the top, and the ends thereof are fixed to the corresponding columns 2, respectively.
[0037]
