Description

Technical Field

[0001] The present invention relates to a sound insulation fence in which a sound insulation panel is installed between columns erected on an installation surface at intervals in the longitudinal direction.

Background Art

[0002] Conventionally, there is known a structure in which a fence member is installed between columns erected on an installation surface at intervals in the longitudinal direction (see, for example, Patent Document 1). Patent Document 1 discloses a fence member support structure capable of supporting a fence member with the same support structure even at locations where the inclination of the installation surface is different, and describes forming a curtain portion that hides a gap formed between the lower end of the fence member and the installation surface on which the fence member is installed.

[0003] In the fence member support structure described in Patent Document 1, by hiding the gap between the lower end of the fence member and the installation surface with a curtain portion, the appearance can be improved and it is possible to prevent articles from falling through the gap. However, since the main purposes are to improve the appearance and prevent falling objects, a slight gap is allowed to exist between the fence member and the installation surface, and there is concern that noise may leak through the gap.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In view of the above circumstances, the present invention is made, and an object thereof is to provide a sound insulation fence capable of effectively reducing noise leaking from a gap between a sound insulation panel and an installation surface.

Means for Solving the Problems

[0006] The present invention provides the following means for solving the above-mentioned problems. Specifically, the present invention is a soundproof fence comprising support posts erected on an installation surface at intervals in the longitudinal direction, soundproof panels attached between each support post, and a sound-insulating member formed separately from the soundproof panels and positioned below the soundproof panels, wherein the sound-insulating member has a sound-insulating portion that contacts the installation surface from the lower end of the soundproof panel. As a result, the gap between the soundproof panel and the installation surface is sealed by the sound-insulating portion, thereby blocking and effectively reducing noise leaking through the gap.

[0007] In the soundproof fence with the above configuration, the support post comprises a base plate and a column portion extending vertically upward from the base plate. The column portion has a web portion, a stepped portion positioned on the longitudinal side of the web portion on which the soundproof panel is placed, and a vertical plate portion positioned below the stepped portion. The sound-insulating portion of the soundproofing member may be in contact with or close in width to the vertical plate portion. As a result, noise passing through the gap between the web portion and the sound-insulating portion of the support post is blocked by the vertical plate portion, thereby effectively reducing noise.

[0008] In the soundproof fence with the above configuration, the vertical plate portion may be formed to extend from the base plate to the stepped portion in the vertical direction, and the entire end in the width direction may be connected to the web portion. This allows the gap between the web portion and the soundproof portion of the support post to be sealed almost completely by the vertical plate portion, thereby effectively blocking and reducing noise.

[0009] In the soundproof fence with the above configuration, the soundproofing member may have an elastically deformable spacer provided at the lower end of the soundproofing section. This allows the lower end of the soundproofing section to deform to conform to the surface shape of the installation surface, thereby minimizing the gap between the soundproofing panel and the installation surface and effectively blocking noise. [Effects of the Invention]

[0010] According to the sound-insulating fence of the present invention, the gap between the sound-insulating panel and the installation surface is sealed by the sound-insulating part, so noise leaking through that gap can be blocked and effectively reduced. [Brief explanation of the drawing]

Embodiments for Carrying out the Invention

[0012] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0013] FIG. 1 is a front view showing a sound insulation fence 100 according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along the line A1 - A1 in FIG. 1. The sound insulation fence 100 has a configuration including columns 7 erected on an installation surface G at intervals in the longitudinal direction, a sound insulation panel 1 attached between the columns 7, and a sound insulation member 8 formed separately from the sound insulation panel 1 and disposed below the sound insulation panel 1. In FIG. 1, the illustration inside the sound insulation panel 1 is omitted to simplify the drawing. Also, in FIG. 1, the left - right direction is taken as the longitudinal direction, the up - down direction is taken as the vertical direction, and the direction perpendicular to the longitudinal direction and the vertical direction is taken as the width direction for the description.

[0014] The soundproof panel 1 is installed between the support columns 7 by inserting each vertical frame 3 from above between the first flange portion 72 and the second flange portion 73 of the support column 7, and placing the lower frame 2B on the stepped portion 75 of the support column 7. When the soundproof panel 1 is attached to the support column 7, the vertical frame 3 is positioned at the top between the first flange portion 72 and the second flange portion 73, so movement in the width direction is restricted and detachment from the support column 7 is prevented. In addition, when the soundproof panel 1 is attached, the vertical frame 3 is positioned at the bottom between the contact portion 76 of the support column 7 and the second flange portion 73, so movement in the width direction is restricted and detachment from the support column 7 is prevented.

[0015] The sound insulation member 8 has its base 81 sandwiched between the stepped portion 75 and the lower frame 2B of the soundproof panel 1, thereby restricting its movement. Furthermore, since the contact plate portion 81a of the sound insulation member 8 is positioned behind the lower frame 2B, the forward movement of the sound insulation member 8 in the width direction can be prevented by the contact between the contact plate portion 81a and the lower frame 2B. In addition, with the backward movement in the width direction restricted by the contact between the sound insulation portion 82 and the vertical plate portion 77, the contact between the contact plate portion 81a of the sound insulation member 8 and the lower frame 2B is expected to restrict the backward movement of the soundproof panel 1 in the width direction. In this way, the movement of the soundproof panel 1, the support column 7, and the sound insulation member 8 is restricted without the use of fixing means such as screws or bolts.

[0016] Figure 3 is a view along the A2-A2 arrow in Figure 1. When attached to the support column 7, the gap-filling material 6 of the soundproof panel 1 is positioned to fill the gap between the outer frame portion 5 of the vertical frame 3 and the web portion 71 of the support column 7. The gap-filling material 6 is provided so that each flat shielding portion 61 protruding in the longitudinal direction deforms to bend significantly, and a part of its surface contacts the surface of the web portion 71. By forming the gap-filling material 6 in this way, even if errors occur in the spacing between the support columns 7 or misalignment of the soundproof panel 1 during construction, causing the distance between the web portion 71 and the vertical frame 3 to fluctuate, the shielding portion 61 can deform to bend in the width direction, thereby filling the gap between the web portion 71 and the vertical frame 3.

[0017] The gap-filling material 6 is preferable because, as shown in Figure 3, each shielding portion 61 can be easily deformed to bend in the width direction, with a projection of 30 mm in the longitudinal direction of the shielding portion 61 and a thickness of 2 mm in the width direction. The thickness of each shielding portion 61 is preferably 1% or more and 25% or less of the projection in the longitudinal direction, and more preferably 1% or more and 15% or less, in order to allow it to be easily deformed to bend in the width direction.

[0018] Furthermore, since the gap-filling material 6 has shielding sections 61 that deform to flex in the width direction, positioned between the first flange section 72 and the second flange section 73 of the support column 7, strong winds from the width direction are blocked by the flange sections 72 and 73 and do not directly hit the shielding sections 61. This suppresses deformation of the shielding sections 61 due to wind, and allows for a stable noise shielding effect from the shielding sections 61.

[0019] Next, the soundproof panel 1 provided on the sound barrier 100 will be described. Figure 4 is a front view showing an example of the soundproof panel 1 provided on the sound barrier 100, Figure 5 is a right side view of the soundproof panel 1, Figure 6 is a top view of the soundproof panel 1, and Figure 7 is an enlarged view of a part of Figure 6. The soundproof panel 1 has a rectangular frame body in which vertical frames 3 are connected to both ends in the longitudinal direction of the upper frame 2A and lower frame 2B, and is formed in a rectangular box shape with a front panel 11 and a back panel 12 arranged inside this frame body. The gap-filling material 6 described above is attached to each vertical frame 3. The gap-filling material 6 is formed so that a part of it protrudes longitudinally from the vertical frame 3 to form a gap-filling part. Note that in Figure 4, the illustration of the through hole 11a, which will be described later, has been partially omitted to simplify the drawing.

[0020] Figure 8 is an enlarged view of a portion of the A3-A3 cross-section in Figure 4, showing a magnified view of the upper part of the soundproof panel 1. The soundproof panel 1 has sound-absorbing material 13 installed between the front panel 11 and the back panel 12, and is configured to attenuate noise entering the inside of the soundproof panel 1 through numerous circular through-holes 11a formed over almost the entire surface of the front panel 11. The back panel 12 is a sound-insulating panel and functions to block noise from the front panel 11 side. The front panel 11 and the back panel 12 are rectangular plate-shaped bodies and are made of a composite material of metal and synthetic resin. Specifically, they are composite panels in which aluminum alloy plates are attached to the entire surface of both sides of a synthetic resin plate. In addition, a sound-insulating auxiliary plate 14 made of plated steel plate is attached to almost the entire inner surface in the width direction of the back panel 12 to improve sound insulation performance.

[0021] The upper frame 2A is a long body formed from an extruded aluminum alloy profile, with the same cross-sectional shape along its entire length. The upper frame 2A is provided in a roughly rectangular cylindrical shape with a hollow portion 20 on the inside, and has grooves 21 that open inward in the vertical direction. Two grooves 21 are formed spaced apart in the width direction, and the end of the front plate 11 is inserted into one groove 21, and the end of the back plate 12 is inserted into the other groove 21 to attach them.

[0022] Figure 9 is a front view of the upper frame 2A provided on the soundproof panel 1, Figure 10 is a top view of the upper frame 2A, and Figure 11 is a right side view of the upper frame 2A. The upper frame 2A is equipped with a trim piece 25, which is attached to the inside of the groove 21. Specifically, an engagement groove 21a is formed on the inner surface near the opening edge of the groove 21, and an engagement projection 26 corresponding to the shape of the engagement groove 21a is formed on the trim piece 25. The trim piece 25 is attached to the inside of the groove 21 by inserting and engaging the engagement projection 26 into the engagement groove 21a.

[0023] The upper frame 2A has screw grooves 23 formed on the inside, with a roughly circular cross-sectional shape. The screw grooves 23 have a roughly C-shaped cross-section and are provided to form so-called screw holes at their longitudinal ends, into which the male threaded portion of a screw can be screwed in from the outside. One screw groove 23 is formed near the base of each groove 21, and one is formed on each trim piece 25. In other words, when the trim pieces 25 are attached, a total of four screw grooves 23 are formed on the upper frame 2A.

[0024] Furthermore, as shown in Figure 8, by attaching the retaining strip 25 so as to narrow the groove width near the opening of the groove 21, the movement of the front plate 11 and the back plate 12 in the width direction is restricted, vibration of the front plate 11 and the back plate 12 is suppressed, and detachment from the groove 21 is prevented. A retaining member R made of a metal plate that protrudes in the width direction from the plate surface is attached to the end of the front plate 11 that is inserted into the groove 21. This retaining member R abuts against the retaining strip 25, effectively preventing the front plate 11 from detaching from the groove 21. In addition, a retaining member (not shown) made of a rivet that penetrates the back plate 12 is attached to the end of the back plate 12 that is inserted into the groove 21, and similar to the retaining member R, it prevents the back plate 12 from detaching from the groove 21. Furthermore, the lower frame 2B is formed to have the same cross-sectional shape as the upper frame 2A, but is positioned with its orientation reversed. The front panel 11 and the back panel 12 are attached to it in the same way as the upper frame 2A shown in Figure 8.

[0025] Figure 12 is an enlarged view of a portion of the A4-A4 cross-section in Figure 4, showing a magnified view of the area around the vertical frame 3 on the right side of Figure 4. The vertical frame 3 has an inner frame portion 4 and an outer frame portion 5, which are formed separately. The inner frame portion 4, which is positioned on the inside in the longitudinal direction, and the outer frame portion 5, which is positioned on the outside in the longitudinal direction, are integrated by engagement. The inner frame portion 4 and the outer frame portion 5 are elongated bodies formed from extruded aluminum alloy profiles, and their cross-sections are the same shape along their entire length in the longitudinal direction.

[0026] Figure 13 is a front view of the vertical frame 3 provided in the soundproof panel 1, Figure 14 is a plan view of the vertical frame 3, and Figure 15 is a diagram showing the state in Figure 14 where the inner frame portion 4, the outer frame portion 5, and the gap-filling material 6 are separated. Figure 13 shows the vertical frame 3 located on the right side in Figure 4. The inner frame portion 4 of the vertical frame 3 is formed in a substantially rectangular cylindrical shape with a hollow portion on the inside, and an engaging portion 43 that engages with the outer frame portion 5 is formed on the base portion 40 which constitutes the outer end in the longitudinal direction. The engaging portion 43 is provided in a ridge-like outer shape that protrudes outward in the longitudinal direction, and the protruding tip is formed to be wider than the base. In addition, the inner frame portion 4 has a groove portion 41 that opens inward in the longitudinal direction, and two groove portions 41 are provided spaced apart in the width direction. Each groove portion 41 is provided so as to be inserted into and attached to the ends of the front plate 11 and the back plate 12.

[0027] The outer frame portion 5 of the vertical frame 3 is formed in a substantially U-shape in cross-section, having a base portion 50 that constitutes the inner end in the longitudinal direction, and substantially flat extension portions 51 that extend outward in the longitudinal direction from both ends of the base portion 50 in the width direction, and a cylindrical portion 52 between each extension portion 51 with the base portion 50 as part of the cylindrical wall. The base portion 50 has an engaging portion 53 that can engage with an engaging portion 43. The engaging portion 53 is provided in the shape of a recessed groove into which the engaging portion 43 can be inserted, and is formed in the shape of a bag groove, with the groove width near the opening being narrower than the back side. In other words, the bag groove-shaped engaging portion 53 functions as an engaging receiving portion that engages with the engaging portion 43 of the inner frame portion 4. The inner frame portion 4 is integrally attached to the outer frame portion 5 by inserting its engaging portion 43 into the inside of the engaging portion 53 of the outer frame portion 5 from its longitudinal end and engaging it, and by bringing the base portion 40 into contact with the base portion 50. Furthermore, the vertical frame 3 has an engaging portion 43 of the inner frame portion 4 formed in a ridge shape, and an engaging portion 53 of the outer frame portion 5 formed in a groove shape. However, the engaging portion 43 may be formed in a groove shape that functions as an engaging receiving portion, and the engaging portion 53 may be formed in a ridge shape that can engage with the engaging portion 43, or the engaging portion 43 and the engaging portion 53 may be formed in other shapes that function as an engaging portion and an engaging receiving portion.

[0028] The outer frame portion 5 has an engaging portion 56 formed at its longitudinal outer end. The engaging portion 56 is a recessed groove formed in the cylindrical portion 52, and is formed in a bag-shaped groove with a groove width that is narrower near the opening than at the back. The engaging portion 56 is also formed to have a screw insertion portion 56a with a substantially circular cross-section that constitutes a so-called screw hole into which the male threaded portion of a screw can be screwed in from the outside of the longitudinal end at the opening.

[0029] The gap-filling material 6 described above is a long, elongated body made of an elastic material, and is made of an olefin-based elastomer. The gap-filling material 6 has a cross-section that is the same shape along its entire length and includes an engaging portion 66 that can engage with the engaging portion 56, and a shielding portion 61 that extends outward in the longitudinal direction from the engaging portion 66. The engaging portion 66 is formed to have an outer shape that corresponds to the inner shape of the engaging portion 56, and by inserting it inward from the longitudinal end of the engaging portion 56 and engaging it, it is prevented from coming loose in the longitudinal direction and is attached to the outer frame portion 5. Furthermore, when the engaging portion 66 is engaged with the engaging portion 56, the male threaded portion of the screw B1 is screwed into the inside of the screw insertion portion 56a from both the longitudinal outer sides and fixed, thereby restricting the longitudinal movement of the gap-filling material 6 and preventing it from coming loose from the outer frame portion 5.

[0030] The shielding portion 61 of the gap-filling material 6 is formed in the shape of a vertically elongated rectangular flat plate, and two shielding portions 61 are provided extending from the engaging portion 66. Specifically, in a plan view, the shielding portion 61 extending inclined toward one side in the width direction from the engaging portion 66 and the shielding portion 61 extending inclined toward the other side in the width direction are arranged in a roughly V-shape. Each shielding portion 61 is formed in the shape of a roughly rectangular flat plate with a thickness of 2 mm in the width direction and a projection of 30 mm in the longitudinal direction. Since each shielding portion 61 is made of a highly flexible olefin-based elastomer, it easily undergoes elastic deformation to bend significantly when subjected to external force. Although the material forming the gap-filling material 6 is an olefin-based elastomer, it is not limited to this, and other thermoplastic resin elastomers other than polyolefins, thermosetting resin elastomers, natural rubber, synthetic rubber, and other elastic materials can be suitably selected or combined. Each shielding portion 61 is provided to constitute the gap-filling portion.

[0031] As shown in Figure 13, the vertical frame 3 is formed such that the outer frame portion 5 is larger than the inner frame portion 4 in the vertical direction, and the ends of the outer frame portion 5 protrude above the upper end and below the lower end of the inner frame portion 4, respectively. The ends of the upper frame 2A and the lower frame 2B are brought into contact with the base portions 50 of each of these protruding ends of the outer frame portion 5, and the male threads of screws (not shown) are screwed into the screw holes formed by the screw grooves 23 of the upper frame 2A and the lower frame 2B from the longitudinal outside of the base portion 50, thereby fixing the vertical frame 3 to the upper frame 2A and the lower frame 2B. In other words, the outer frame portion 5 of the vertical frame 3 is positioned on the longitudinal outside of the upper frame 2A and the lower frame 2B, and the inner frame portion 4 is positioned between the upper frame 2A and the lower frame 2B.

[0032] Furthermore, as shown in Figure 12, the front panel 11 and the rear panel 12 are attached to the inner frame 4 by inserting their ends into the grooves 41 of the inner frame 4. Also, the vertical frame 3 on the left side of Figure 4 has the same shape as the vertical frame 3 shown in Figures 13 to 15, but is arranged with its left and right orientation reversed, and the front panel 11 and rear panel 12 are attached in the same way as the vertical frame 3 shown in Figure 12.

[0033] Next, the support posts 7 provided on the sound barrier 100 will be described. Figure 16 is a perspective view showing an example of a support post 7 provided on the sound barrier 100, Figure 17 is a front view of the support post 7, Figure 18 is a right side view of the support post 7, and Figure 19 is a plan view of the support post 7. The support post 7 has a base plate 79 installed on the installation surface G and a column portion 70 extending vertically upward from the base plate 79. The column portion 70 is formed in a substantially H-shape in cross-section and includes a web portion 71 connected to approximately the center of the base plate 79, a first flange portion 72 connected to the front end of the web portion 71 in the width direction, and a second flange portion 73 connected to the rear end of the web portion 71 in the width direction. The second flange portion 73 is formed in a substantially rectangular flat plate shape overall and is arranged perpendicular to the base plate 79. The first flange portion 72 has a curved shape at its lower end, with the gap between it and the second flange portion 73 decreasing as it approaches the top. Near the top end, it is formed in a substantially flat shape with the gap between it and the second flange portion 73 being approximately the same size both vertically and horizontally. As shown in Figure 17, the first flange portion 72 is formed to have the same longitudinal size throughout its entire length from the top end to the bottom end, and similarly, the second flange portion 73 is formed to have the same longitudinal size as the first flange portion 72.

[0034] At the lower part of the support column 7, stepped portions 75 with a flat upper surface are formed on both sides in the longitudinal direction of the web portion 71. Each stepped portion 75 is formed in a substantially flat plate shape that protrudes from both sides in the longitudinal direction from the web portion 71, and its longitudinal size is the same as that of the second flange portion 73. In addition, the rear end of each stepped portion 75 is connected to the second flange portion 73. The upper surface of the stepped portion 75 is positioned parallel to the base plate 79 and is provided so as to be positioned parallel to the installation surface G.

[0035] At the lower part of the support column 7, vertical plate sections 77 are formed on both sides of the web section 71. Each vertical plate section 77 is formed in the shape of a rectangular flat plate with its surface oriented in the width direction, its upper end positioned near the front end of the stepped section 75, and its lower end connected to the base plate 79.

[0036] Each support column 7 has rectangular, flat contact portions 76 that protrude longitudinally on both sides of the web portion 71. Each contact portion 76 is arranged in a vertical plate shape with its surface facing the width direction and is positioned parallel to the second flange portion 73. The distance between the surface of each contact portion 76 and the inner surface of the second flange portion 73 is larger than the width of the vertical frame 3 of the soundproof panel 1.

[0037] Figure 20 is a front view showing the two support columns 7 installed on the installation surface G. Each support column 7 shown in Figure 20 is positioned at intervals corresponding to the length of the soundproof panel 1, and is fixed by having the lower surface of the base plate 79 abut against the installation surface G and using anchor bolts (not shown) embedded and fixed in the installation surface G.

[0038] Figure 21 is a front view showing the state in which the sound-insulating members 8 are installed between the support columns 7 in Figure 20. The sound-insulating members 8 are installed to seal the gap between the soundproof panel 1 installed between the support columns 7 and the installation surface G, and to prevent noise from passing from the front side in the width direction to the rear side.

[0039] Figure 22 is a front view of the sound insulation member 8, and Figure 23 is a right side view of the sound insulation member 8. The sound insulation member 8 comprises a rectangular flat plate-shaped sound insulation section 82 arranged vertically with its lower end abutting against the installation surface G, and a rectangular flat plate-shaped base section 81 extending backward in the width direction from the upper end of the sound insulation section 82. The base section 81 also has a contact plate section 81a extending upward at its rear end. The base section 81 and the sound insulation section 82 are formed by bending a metal plate, specifically made of galvanized steel. A long spacer 82a with a rectangular cross-section made of an elastic material is attached to the lower end of the sound insulation section 82 over approximately its entire length in the longitudinal direction.

[0040] Figure 24 is a cross-sectional view taken along line A5-A5 in Figure 21. In the sound-insulating member 8 shown in Figures 21 and 24, the sound-insulating portions 82 are positioned in front of the vertical plate portions 77 at both ends in the longitudinal direction, and the base portion 81 is placed on the stepped portion 75 of each support column 7. The sound-insulating member 8's movement in the width direction backward is restricted by the contact of the sound-insulating portion 82 with the vertical plate portions 77. Also, as shown in Figure 24, the gap between the sound-insulating portion 82 and the installation surface G is closed by an elastically deformable spacer 82a.

[0041] Figure 25 shows the state in which a fixing member F is attached between the support column 7 and the soundproof panel 1. The fixing member F is a spring member and is positioned between the vertical frame 3 and the second flange portion 73, with a part of it in contact with the upper surface of the upper frame 2A. The upper end of the vertical frame 3 of the soundproof panel 1, which is biased to move away from the second flange portion 73 by the fixing member F, is strongly pressed against the inner surface of the first flange portion 72, thereby suppressing vibrations and rattling of the soundproof panel 1 when it is subjected to strong winds or vibrations from vehicles traveling nearby.

[0042] In this embodiment, the soundproof fence 100 with the above configuration includes a pair of support posts 7 erected on the installation surface G at intervals in the longitudinal direction, a soundproof panel 1 attached between each support post 7, and a soundproofing member 8 formed separately from the soundproof panel 1 and positioned below the soundproof panel 1. The soundproofing member 8 has a soundproofing portion 82 that extends from the lower end of the soundproof panel 1 to the installation surface G and makes contact. As a result, the gap between the soundproof panel 1 and the installation surface G is sealed by the soundproofing portion 82, thereby blocking and effectively reducing noise.

[0043] Furthermore, the support column 7 comprises a base plate 79 and a column portion 70 extending vertically upward from the base plate 79. The column portion 70 has a web portion 71, a stepped portion 75 positioned on the longitudinal side of the web portion 71 on which the soundproofing panel 1 is placed, and a vertical plate portion 77 positioned below the stepped portion 75. The sound-insulating portion 82 of the sound-insulating member 8 is positioned in contact with the vertical plate portion 77. As a result, noise passing through the gap between the web portion 71 and the sound-insulating portion 82 of the support column 7 is blocked by the vertical plate portion 77, thereby effectively reducing noise. The sound-insulating portion 82 may also be positioned close to the vertical plate portion 77 in the width direction.

[0044] Furthermore, the vertical plate portion 77 is formed to extend from the base plate 79 to the stepped portion 75 in the vertical direction, and its entire end in the width direction is connected to the web portion. As a result, the gap between the web portion 71 of the support column 7 and the sound insulation portion 82 can be sealed almost completely by the vertical plate portion 77, so that noise can be blocked and effectively reduced by the vertical plate portion 77.

[0045] Furthermore, since the sound insulation member 8 has an elastically deformable spacer 82a provided at the lower end of the sound insulation portion 82, the spacer 82a allows the lower end of the sound insulation portion 82 to deform to follow the surface shape of the installation surface G, thereby minimizing the gap between the soundproof panel 1 and the installation surface G, and effectively blocking noise. Alternatively, instead of the spacer 82a, an elastically deformable plate material 83 may be attached to the lower end of the sound insulation portion 82, as shown in Figure 26. The plate material 83 is made of an elastic material such as rubber, and is a long body provided over substantially the entire length in the longitudinal direction of the lower end of the sound insulation portion 82. In the modified example shown in Figure 26, the plate material 83 is fixed to the lower end of the sound insulation portion 82 by fixing means such as rivets 84.

[0046] The embodiments disclosed herein are illustrative in all respects and are not intended to be restrictive. The technical scope of the present invention is not construed solely by the embodiments described above, but is defined by the claims. Furthermore, the technical scope of the present invention includes all modifications within the meaning and scope of equivalence to the claims.

[0047] For example, in the above embodiment, each shielding portion 61 of the gap-filling material 6, which functions as a gap-filling portion, is made to have a flat outer shape, thereby forming the entire shielding portion 61 into a narrow shape where the width is smaller than the size of the protrusion, but it is not limited to this. The shielding portion 61 may be formed in another shape in which a narrow portion whose width is smaller than the size of the protrusion in the longitudinal direction is part of the shielding portion 61, so that the shielding portion 61 can be easily bent in the width direction. Also, the gap-filling material 6 is formed to have two protruding shielding portions 61, but it is not limited to this, and it may be formed to have one protruding shielding portion 61, or three or more protruding shielding portions 61.

[0048] Furthermore, in the above embodiment, the soundproof panel 1 is formed by engaging an inner frame portion 4 and an outer frame portion 5, which are formed separately, to form a vertical frame 3. However, it is not limited to this, and the vertical frame 3 may be formed from a single elongated body, or from a combination of three or more elongated bodies.

[0049] Furthermore, in the above embodiment, the soundproof panel 1 has through holes 11a formed on substantially the entire surface of the front panel 11, but it is not limited to this, and the front panel 11 may function as a sound insulation panel in the same way as the back panel 12 without forming through holes 11a.

[0050] Furthermore, in the above embodiment, the soundproof panel 1 is configured with sound-absorbing material 13 sandwiched between the front panel 11 and the back panel 12, but it is not limited to this configuration, and it may also be configured with only one sound-insulating panel, omitting the sound-absorbing material.
