Description

[Technical field]

[0001] The present invention relates to a soundproof panel that is installed at a construction site, a demolition site, or the like. [Background technology]

[0002] Traditionally, at construction sites, demolition sites, and other construction sites, scaffolding is used to carry out work. In such cases, it is common to cover the sides of the scaffolding with sheets or soundproof panels to minimize the leakage of dust and noise generated at the construction site.

[0003] When a typhoon or other storm passes, soundproofing panels installed on the sides of scaffolding are subjected to lateral loads from strong winds. This effect is particularly noticeable at high-altitude sites such as buildings. For this reason, when strong winds are expected, it has become necessary to take measures against strong winds, such as temporarily removing soundproofing panels.

[0004] Therefore, in Patent Document 1, the soundproof panel covering the side portion (called a protective panel in Patent Document 1) is configured to be openable and closable. This allows wind to pass through the gaps in the open soundproof panel, reducing the load caused by the wind. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2021-110108 A Summary of the Invention [Problem to be solved by the invention]

[0006] Incidentally, in the soundproof panel of Patent Document 1, the soundproof panel is opened and closed by sliding horizontally along a rail. However, dust and the like generated from the work site hits the soundproof panel on the side and falls, and tends to accumulate on the rail under the feet. When dust and the like accumulates on the rail, sliding movement becomes difficult. In particular, in the case of demolition sites, a large amount of dust such as fine concrete powder may be generated, and this tendency is prominent.

[0007] The present invention has been made in consideration of the above problems, and has an object to provide a soundproof panel that is easy to open and close. [Means for solving the problem]

[0008] The soundproofing panel for solving the above problems is as follows: A soundproof panel that covers the periphery of a construction object at a construction site, A frame body having at least a vertical frame extending in the vertical direction; A panel body covering the inside of the frame body; A guide rail provided along the vertical frame, The panel body is made up of a plurality of panels arranged in a vertical direction, At least one of the panel bodies is configured to be slidable in the up and down direction along the guide rail, so that the panel body is configured to be openable and closable, An upper panel of the panel body is configured to be slidably moved in the up and down direction along the guide rail, The lower panel of the panel body is fixed to the frame body.

[0009] This allows the panel body to be opened to allow wind to pass through when strong winds are expected, thus eliminating the need to dismantle and remove the soundproof panel in the event of strong winds.

[0010] In addition, because the guide rail is provided to extend vertically along the vertical frame, dust and other particles are less likely to accumulate on the guide rail. Therefore, by configuring a portion of the panel body to slide vertically along the guide rail, it is possible to preferably prevent the sliding movement from becoming difficult even in a site where dust and other particles are likely to be generated.

[0012] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a specific embodiment of a "soundproof panel" according to the present invention will be described with reference to the drawings.

[0013] (First embodiment) As shown in Fig. 1, at a construction site, demolition site, civil engineering site, or other construction site, temporary scaffolding 11 is set up around a building 10. The building 10, which is the construction object, is an object to be constructed at a construction site or civil engineering site, and is an object to be demolished at a demolition site.

[0014] This scaffolding 11 has a well-known configuration and, for example, comprises a plurality of vertical supports 12, horizontal scaffolding piping 13 fixed between the vertical supports 12, and scaffolding boards 14 attached to the horizontal scaffolding piping 13.

[0015] As shown in Fig. 2, the soundproof panel 20 is provided on the side of the scaffolding 11 and covers the side of the scaffolding 11. More specifically, the soundproof panel 20 is provided on the side of the scaffolding 11 opposite the building 10, and covers the side of the scaffolding 11 to prevent dust such as fine concrete powder generated at the construction site and noise from leaking to the outside. The soundproof panel 20 also plays a role in preventing objects other than dust (such as tools) from falling and workers from falling. Note that Fig. 2 shows the soundproof panel 20 in a schematic manner, and a detailed configuration and drawings will be described later.

[0016] Conventionally, soundproof panels are expected to play a role in preventing dust and noise from leaking to the outside, so they do not allow wind to pass through. Therefore, when a strong wind blows, the wind load is applied to the soundproof panel, making it easy to be blown by the wind. In addition, depending on the height of the building, scaffolding may be installed across multiple floors, and in this case, there is a risk of it being blown by the strong wind and collapsing. Therefore, in the past, when the weather was expected to be strong wind (for example, in the case of a typhoon), the soundproof panel and scaffolding were once dismantled and removed, which was very troublesome. Therefore, in this embodiment, the soundproof panel 20 is configured as follows. A detailed explanation will be given below. Note that FIG. 3 is a front view of the soundproof panel 20 when viewed from the outside (so-called front side), and FIG. 4 is a back view of the soundproof panel 20 when viewed from the side of the building 10 (the side of the scaffolding 11) (so-called back side).

[0017] As shown in Figures 3 and 4, the soundproof panel 20 comprises a rectangular frame body 30, a panel body 40 covering the inside of the frame body 30, and a guide rail 50 (see Figure 6) attached to the frame body 30.

[0018] First, the frame body 30 will be described. As shown in Fig. 3, the frame body 30 has a pair of vertical frames 31 and a pair of horizontal frames 32, and is rectangular in shape with the horizontal frames 32 being longer than the vertical frames 31. The soundproof panel 20 is usually arranged so that the vertical frames 31 run along the up-down direction and the horizontal frames 32 run along the left-right direction (horizontal direction). In other words, the vertical frames 31 are arranged on both the left and right sides, and the horizontal frames 32 are arranged on the top and bottom sides.

[0019] As shown in Figures 4 and 6, the vertical frame 31 is provided with a guide rail 50 that extends along the vertical frame 31 (i.e., along the up-down direction). As shown in Figure 6, the guide rail 50 has a substantially U-shaped cross section, and in this embodiment, is formed integrally with the vertical frame 31. This guide rail 50 is provided on the side surface of the vertical frame 31 that faces the building 10. In other words, the guide rail 50 is formed so as to protrude from the left and right ends of the vertical frame 31 towards the building 10 (inward in the depth direction), and the tip portion on the building 10 side in the depth direction is formed so as to bend inward in the left and right direction.

[0020] In this embodiment, the depth direction is a direction perpendicular to the soundproof panel 20, with the building 10 side corresponding to the inside in the depth direction and the side opposite the building 10 corresponding to the outside in the depth direction. In addition, since the panel body 40 is provided symmetrically, only one side in the left-right direction is illustrated in FIG. 6.

[0021] Next, the panel body 40 will be described. As shown in Figures 3 and 4, the panel body 40 is made up of multiple sheets arranged in a vertical direction. The panel body 40 of this embodiment has an upper panel 41 and a lower panel 42. The lower panel 42 is made up of a single rectangular plate that is impermeable to dust and other particles, and is fixed to the lower part of the frame body 30 so as to cover almost the entire lower half of the frame body 30.

[0022] At this time, as shown in Fig. 6(b), the lower panel 42 is fixed in the depth direction to the outside of the frame body 30 (the side opposite the building 10) by a fixing member such as a rivet. In this embodiment, a casing frame 33 that covers the outside in the depth direction and the left and right side surfaces at the left and right ends of the lower panel 42 and restricts movement in the depth direction and the left and right directions is integrally formed with the vertical frame 31. As shown in Fig. 3, a casing frame 34 that covers the outside in the depth direction and the lower surface at the lower end of the lower panel 42 and restricts movement in the depth direction and downward direction is integrally formed with the lower horizontal frame 32.

[0023] The panel body 40 also includes a long and narrow auxiliary panel 43 above the upper panel 41 to fill the gap between the upper horizontal frame 32 and the upper panel 41. The auxiliary panel 43 is fixed to the outside of the frame body 30 in the depth direction by a fixing member such as a rivet, similar to the lower panel 42. As shown in FIG. 6(a), the auxiliary panel 43 includes a casing frame 35 that covers the outside in the depth direction and the left and right side surfaces at the left and right ends of the auxiliary panel 43 in the depth direction and restricts movement in the depth direction and the left and right directions and is integrally formed with the vertical frame 31. As shown in FIG. 4, the upper horizontal frame 32 includes a casing frame 36 that covers the outside in the depth direction and the upper surface at the lower end of the auxiliary panel 43 and restricts movement in the depth direction and the upward direction and is integrally formed with the vertical frame 31.

[0024] 3 and 4, like the lower panel 42, the upper panel 41 is made of a single rectangular plate to prevent the passage of dust and dirt, and is large enough to cover almost the entire upper half of the frame 30. The upper panel 41 is attached to the frame 30 so as to be slidable along the vertical frame 31 (i.e., in the up-down direction). The structure for enabling the sliding movement will be described later. The shape of the upper panel 41 is determined so that the lower end of the upper panel 41 overlaps with the upper end of the lower panel 42 in the depth direction when closed.

[0025] As shown in Fig. 5, an upper reinforcing member 44 extending straight in the left-right direction is provided above the upper panel 41. As shown in Fig. 6(a) and other figures, the upper reinforcing member 44 is fixed to the inside in the depth direction (back side) of the upper panel 41 by a fixing member such as a rivet. Also, as shown in Fig. 7, the upper reinforcing member 44 is made of a metal material and has an L-shaped cross section, with its lower end formed to protrude to the inside in the depth direction (towards the building 10).

[0026] Similarly, as shown in Fig. 5, a lower reinforcing member 45 extending straight in the left-right direction is provided below the upper panel 41. The lower reinforcing member 45 is fixed to the inside in the depth direction (back side) of the upper panel 41 by a fixing member such as a rivet. Also, as shown in Fig. 8, the lower reinforcing member 45 is made of a metal material and has an L-shaped cross section, with its upper end portion formed so as to protrude to the inside in the depth direction (towards the building 10). The upper reinforcing member 44 and the lower reinforcing member 45 reinforce the upper panel 41 and suppress warping and the like.

[0027] 4 and 6, a locking mechanism 46 for restricting sliding movement is provided on the inside in the depth direction (the side toward the building 10) of the upper panel 41. This locking mechanism 46 is fixed to both left and right ends of the upper reinforcing member 44. More specifically, at both left and right ends of the upper reinforcing member 44, it is fixed via bolts 44a to the underside of the lower end that protrudes toward the building 10 in the depth direction.

[0028] As shown in Fig. 9, the locking mechanism 46 includes a rod-shaped bar 46a bent into an L shape. The bar 46a is configured to be movable in the left-right direction. By moving the bar 46a outward in the left-right direction, the tip of the bar 46a can be inserted into a through-hole 50a provided in the guide rail 50, as shown in Fig. 6(a). This allows the upper panel 41 to be engaged with the frame body 30, restricting sliding movement.

[0029] Moreover, by moving the latch 46a inward in the left-right direction, the tip of the latch 46a can be pulled out of the through-hole 50a, thereby releasing the lock and allowing the upper panel 41 to slide.

[0030] 10, when the barb 46a is moved inward in the left-right direction, it can be rotated in the direction of the arrow to lock the barb 46a with a locking plate 46b provided on the inner left-right direction, thereby restricting left-right movement. This prevents the barb 46a from moving outward in the left-right direction and its tip from contacting the guide rail 50 during the sliding movement of the upper panel 41. The configuration of the locking mechanism 46 is not limited to a bar structure, and may be changed arbitrarily as long as it is capable of restricting and releasing the restriction on the sliding movement.

[0031] Next, a configuration for sliding the upper panel 41 will be described. As shown in FIG. 5, inner rails 47 are provided on both the left and right sides of the upper panel 41. The inner rails 47 are accommodated in guide rails 50 provided on the vertical frame 31 and are configured to be movable in the vertical direction. In other words, the guide rails 50 correspond to outer rails for the inner rails 47. To explain in detail, as shown in FIG. 5, the inner rails 47 are formed so as to extend in the vertical direction, and as shown in FIG. 6(a), the cross section is substantially U-shaped. In addition, the outer dimension L1 of the inner rail 47 in the depth direction is configured to be substantially the same as or slightly shorter than the inner dimension of the guide rail 50 so as to be accommodated inside the guide rail 50. The inner rail 47 is configured to be slidable in the vertical direction relative to the guide rail 50.

[0032] As shown in FIG. 6(a), the inner rail 47 is fixed to the left and right ends of the upper panel 41. At this time, the outer surface of the upper panel 41 is fixed to abut against the inner surface of the side wall 47b on the opposite side of the building 10 (the side of the frame body 30) of the side walls 47b, 47c on both sides in the depth direction of the inner rail 47. The bottom part 47a (the end on the outer side in the left and right direction) of the inner rail 47 is disposed outside the left and right ends of the upper panel 41. Note that a through hole 47d is provided in the bottom part 47a of the inner rail 47 at a location facing the bar 46a, and the tip of the bar 46a is configured to be movable in the left and right direction.

[0033] The upper panel 41 is configured to be in line contact with the guide rail 50 via the inner rail 47. Specifically, the inner rail 47 has a plurality of protrusions 48 extending in the up-down direction on its outer surface facing the guide rail 50. More specifically, as shown in Fig. 6(a), the inner rail 47 has protrusions 48a on the outer surface (outer surface in the left-right direction) of the bottom 47a, which protrude outward in the left-right direction (towards the bottom of the guide rail 50), at both ends in the depth direction.

[0034] In addition, the inner rail 47 has two convex parts 48b that protrude outward in the depth direction on the outer surface of the side wall 47b on the outer side in the depth direction (the side opposite the building 10). These convex parts 48b are provided at positions spaced a predetermined distance apart in the left-right direction. In addition, the inner rail 47 has a convex part 48c that protrudes inward in the depth direction on the outer surface of the side wall 47c on the inner side in the depth direction (the side facing the building 10). These convex parts 48a to 48c are provided so as to face the guide rail 50, respectively. The upper panel 41 is in line contact with the guide rail 50 via the convex parts 48a to 48c of the inner rail 47.

[0035] The effects of this embodiment will be described.

[0036] The soundproof panel 20 is configured to be openable and closable because the upper panel 41 of the panel body 40 is configured to be slidable up and down along the guide rails 50. This allows the upper panel 41 to be opened to allow wind to pass through when strong winds are expected. This makes it possible to eliminate the need to dismantle and remove the soundproof panel 20 in the event of strong winds.

[0037] Incidentally, since the panel body 40 covers the inside of the frame body 30, dust and the like such as concrete pieces hit the panel body 40 and fall, and tend to accumulate under the panel body 40. However, since the guide rails 50 are provided to extend vertically along the vertical frame 31, dust and the like are less likely to accumulate on the guide rails 50. Therefore, in the soundproof panel 20 of this embodiment in which the upper panel 41 slides vertically along the guide rails 50, it is possible to suitably slide the panel even in a site where dust and the like are likely to be generated.

[0038] Dust such as concrete pieces hit the panel body 40 and fall, and tend to accumulate under the foot of the panel body 40. For this reason, if the lower panel 42 is configured to be openable, there is a possibility that the dust and the like accumulated under the foot may scatter to the outside when the lower panel 42 is opened. In addition, it is also possible that objects such as lumps of concrete pieces or tools are leaning against the foot of the panel body 40, making it difficult to open the lower panel 42. Therefore, in this embodiment, the upper panel 41 is configured to be slidable. This makes it possible to prevent the dust and the like accumulated under the foot from scattering to the outside. In addition, even if an object is leaning against the foot of the panel body 40, the soundproof panel 20 can be easily opened.

[0039] When the panel body 40 is configured to slide in the vertical direction, it is necessary to shift the upper panel 41 and the lower panel 42 in the depth direction so that they do not interfere with each other when sliding. Here, as shown in FIG. 11(a), when the lower panel 42 is arranged closer to the building 10 than the upper panel 41 (inside in the depth direction), dust and the like from the construction site may accumulate on the upper side of the lower panel 42, and in this case, when the upper panel 41 is opened, there is a possibility that the dust and the like may scatter to the outside. In addition, when the soundproof panel 20 is closed, the gap between the lower panel 42 and the upper panel 41 opens to the upper side inside the soundproof panel 20 and opens to the lower side outside the soundproof panel 20, so that there is a possibility that dust and the like may scatter to the outside from the gap between the lower panel 42 and the upper panel 41 as shown by the arrow.

[0040] 11(b), in this embodiment, the upper panel 41 is disposed closer to the building 10 (inner in the depth direction) than the lower panel 42. As a result, the lower panel 42 is disposed outside (opposite the building 10) compared to the upper panel 41, so that dust and the like falls under the feet of the upper panel 41 (see arrow), preventing dust and the like from accumulating on the upper part of the lower panel 42. In addition, dust and the like can be prevented from scattering to the outside from the gap between the lower panel 42 and the upper panel 41.

[0041] Additionally, the upper panel 41 is in line contact with the guide rail 50 via the inner rail 47. This makes it easier to slide the guide rail 50, even if dust or other particles adhere to the guide rail 50, compared to when the guide rail 50 is in surface contact.

[0042] (Modification) In the above embodiment, as shown in FIG. 12, a seal member 99 may be provided in the gap between the upper panel 41 and the lower panel 42 to close the gap. The seal member 99 is fixed to the inside of the upper end of the lower panel 42 so as to extend in the width direction (left-right direction) in which the lower panel 42 extends. The seal member 99 always abuts against the outside of the upper panel 41, and is in a state of abutting against the lower end of the upper panel 41 when the panel body 40 is closed. This makes it possible to suppress sound, dust, and the like from leaking to the outside through the gap between the upper panel 41 and the lower panel 42. The seal member 99 is fixed to the lower panel 42 because there is a possibility that the inside of the lower panel 42 is uneven due to the adhesion of dust, and if the seal member 99 is fixed to the upper panel 41, it is likely to be rubbed against the unevenness formed on the lower panel 42 and damaged.

[0043] Also, for example, the upper reinforcing member 44 and the lower reinforcing member 45 may be fixed to the outside of the upper panel 41 (the opposite side to the building 10), and the gap may be blocked by the protruding portion of the upper reinforcing member 44 and the lower reinforcing member 45 in the depth direction. In this case, it is preferable that the protruding portion of the lower reinforcing member 45 is disposed between the upper panel 41 and the lower panel 42 when the upper panel 41 is closed. It is also preferable that the protruding portion of the upper reinforcing member 44 is disposed between the upper panel 41 and the auxiliary panel 43 when the upper panel 41 is closed. It goes without saying that the length of the protruding portion in the depth direction is adjusted according to the distance between the upper panel 41 and the lower panel 42 so as to fit into the gap. By configuring in this way, the protruding portion of the upper reinforcing member 44 and the lower reinforcing member 45 in the depth direction can suitably block the gap between the upper panel 41 and the lower panel 42 and the gap between the upper panel 41 and the auxiliary panel 43.

[0044] In the above embodiment, the upper panel 41 is in line contact with the guide rail 50 via the inner rail 47, but the configuration may be changed as desired as long as the upper panel 41 and the guide rail 50 are in point or line contact. For example, instead of providing the protrusion 48 on the outer circumferential surface of the inner rail 47, a protrusion may be provided on the inner circumferential surface of the guide rail 50. Also, the protrusion 48 is formed to extend along the vertical direction, but instead, a plurality of protrusions may be arranged on a straight line along the vertical direction. In this specification, point contact does not only refer to a complete point, but also means that the opposing surfaces of the guide rail 50 and the inner rail 47 are in local contact rather than being in wide surface contact. The same applies to line contact.

[0045] In the above embodiment, the upper panel 41 is configured to slide relative to the guide rails 50 via the inner rails 47, but the inner rails 47 do not have to be provided. For example, the upper panel 41 may be configured to slide on both the left and right sides by the guide rails 50.

[0046] In the above embodiment, both the upper panel 41 and the lower panel 42 may be configured to be slidable.

[0047] In the above embodiment, the auxiliary panel 43 may be omitted. The panel body 40 may be composed of three or more panels. For example, the panel body 40 may be composed of three panels, an upper, middle and lower panel, and the middle panel may be configured to be slidable. In this case, the middle panel may be configured to be slidable upward. In this way, even if dust or the like accumulates at the foot of the soundproof panel 20, the middle panel can be opened upward without being affected. In addition, in this case, when closed, the guide rail 50 is positioned outside the middle panel, so that there is a low possibility that dust or the like will adhere to the guide rail 50, and the middle panel can be opened upward without being affected by dust or the like.

[0048] In the above embodiment, the lower panel 42 may be configured to be disposed closer to the building 10 than the upper panel 41. The lower panel 42 may be configured to be slidable.

[0049] In the above embodiment, the frame 30 is rectangular, but it may be square. Also, the frame 30 may be rectangular with its longer sides in the vertical direction.

[0050] In the above embodiment, the frame body 30 may be provided with a pillar member extending in the vertical direction so as to connect the horizontal frame 32 on the upper side with the horizontal frame 32 on the lower side. For example, a pillar member formed to extend in the vertical direction may be provided in the center of the frame body 30 in the horizontal direction. This pillar member is for reinforcing the frame body 30. When a pillar member is provided, the panel body 40 may be divided into left and right parts, and the locking mechanism 46 and the like may be provided on both the left and right sides of the divided panel body 40.

[0051] Second embodiment In the above embodiment, a frame reinforcing member for reinforcing the frame 30 may be provided. A second embodiment in which the frame reinforcing member is described will be described below with reference to Figs. 13 to 16. The second embodiment will be described based on the soundproof panel 20 of the first embodiment. Note that the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

[0052] As described in the first embodiment, the frame body 30 has a pair of vertical frames 31 extending in the up-down direction and a pair of horizontal frames 32 extending in the left-right direction, and is formed in a horizontally long rectangular shape. Therefore, when the upper panel 41 is slid to open the soundproof panel 20, the shape of the open part needs to be maintained by the frame body 30 alone, and depending on the strength of the frame body 30, reinforcement is required.

[0053] Therefore, in the second embodiment, a frame body reinforcing member 100 as shown in Fig. 13 is provided. Fig. 13 is a rear view showing the soundproof panel 20 of the second embodiment as seen from the building 10 side. The frame body reinforcing member 100 has both ends fixed to the horizontal frames 32, respectively, and is formed into a rod shape extending in the vertical direction. In this way, the frame body reinforcing member 100 connects between the pair of horizontal frames 32 and reinforces the frame body 30.

[0054] In the second embodiment, two frame body reinforcing members 100 are provided. In Fig. 13, the two frame body reinforcing members 100a, 100b are arranged so that the distance from the right-side vertical frame 31 to the right-side frame body reinforcing member 100a, the distance from the right-side frame body reinforcing member 100a to the left-side frame body reinforcing member 100b, and the distance from the left-side frame body reinforcing member 100b to the left-side vertical frame 31 are approximately equal.

[0055] 14 to 16, in order to prevent frame body reinforcing member 100 from interfering with upper reinforcing member 44 and lower reinforcing member 45, which are panel reinforcing members, upper reinforcing member 44 and lower reinforcing member 45 are provided with recesses 144, 145, respectively, at intersections with frame body reinforcing member 100. Recesses 144, 145 are provided so as to open inward in the depth direction, and part or all of frame body reinforcing member 100 is disposed within recesses 144, 145.

[0056] The frame reinforcing member 100 is formed in a rod shape along the up-down direction. Therefore, even if the upper panel 41 is slid, the upper reinforcing member 44 and the lower reinforcing member 45 do not interfere with the frame reinforcing member 100 due to the recesses 144, 145.

[0057] Moreover, the frame body reinforcing member 100 is disposed between the guide rails 50 in the depth direction, and has a thickness such that it does not protrude from the guide rails 50. That is, as shown in FIG. 15, the frame body reinforcing member 100 is disposed inside the upper panel 41 (and the lower panel 42) in the depth direction, and is disposed parallel to the upper panel 41 so as not to interfere with it. Also, the frame body reinforcing member 100 is disposed outside the inner end 150 of the guide rail 50 in the depth direction, and is configured not to protrude inside the inner end 150 of the guide rail 50. That is, when the soundproof panels 20 are stacked, the frame body reinforcing member 100 does not interfere with other soundproof panels 20. Note that FIG. 15 is a cross-sectional view taken along the CC line in FIG. 14.

[0058] By providing the frame reinforcing member 100 as in the second embodiment, it is possible to prevent the frame 30 from being distorted even in a state in which the upper panel 41 is slid open.

[0059] Furthermore, by providing the upper reinforcing member 44 and the lower reinforcing member 45 as panel reinforcing members, the strength of the upper panel 41 that slides in the vertical direction can be increased. Furthermore, although the frame body 30 is formed horizontally long, the frame body reinforcing member 100 is provided to connect the horizontal frames 32, so that the strength of the entire frame body 30 is increased.

[0060] Here, an increase in the thickness of the soundproof panel 20 is undesirable in terms of both handling and the installation environment. On the other hand, the frame reinforcing member 100 is an important element in terms of the strength of the entire soundproof panel 20. Thus, by forming recesses 144, 145 in the upper reinforcing member 44 and the lower reinforcing member 45 and arranging a part or all of the frame reinforcing member 100 in the recesses 144, 145, it is possible to prevent the soundproof panel 20 from increasing in thickness without reducing the strength of the entire soundproof panel 20.

[0061] (Modification of the above second embodiment) In the second embodiment, the frame reinforcing member 100 may be provided to connect between a pair of left and right vertical frames 31. In other words, the frame reinforcing member 100 may be formed in a rod shape extending in the left-right direction, with both ends fixed to the vertical frames 31.

[0062] Moreover, the frame body reinforcing member 100 may be provided so as to connect between the vertical frame 31 and the horizontal frame 32. In other words, the frame body reinforcing member 100 may be formed in a rod shape having one end fixed to the vertical frame 31 and the other end fixed to the horizontal frame 32 and extending in an oblique direction.

[0063] The frame reinforcing member 100 may be provided in a diagonal shape. That is, the frame reinforcing member 100 may be formed in a rod shape along the diagonal line of the frame 30.

[0064] In the second embodiment, the frame reinforcing member 100 is formed in a rod shape, but the shape may be changed as desired as long as it does not block the opening of the soundproof panel 20 when the upper panel 41 is slid. For example, the frame reinforcing member 100 may be formed in a long, thin plate shape.

[0065] In the second embodiment, if the frame reinforcing member 100 does not interfere with the upper reinforcing member 44 and the lower reinforcing member 45, the recesses 144, 145 do not need to be provided.

[0066] In the second embodiment, the number and locations of the frame reinforcing members 100 may be changed as desired.

[0067] In the above embodiment, the soundproof panel 20 is not limited to the side surface of the scaffolding 11, but may be one that surrounds the periphery of a building (construction target). For example, the soundproof panel 20 may be employed as a temporary enclosure panel that surrounds the periphery of a building 10 at a construction site. [Explanation of symbols]
