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 soundproofing panels covering the side parts are configured to be openable and closable, which allows wind to pass through the gaps in the open soundproofing panels, thereby 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] However, when the soundproof panel is fully opened, there is an increased possibility that objects such as tools may fall through the opening.

[0007] The present invention has been made in consideration of the above problems, and an object of the present invention is to provide a soundproof panel that does not allow objects of a certain size or larger to pass through even when opened. [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, A shielding panel body covering the inside of the frame body; A filter member that allows air to pass through while not allowing objects having a size equal to or larger than a predetermined size to pass through, The shielding panel body is configured to be openable and closable, The filter member is fixed to the frame body so as to cover at least an opening formed when the shielding panel body is opened, The frame body has at least a vertical frame extending in the up-down direction, The vertical frame is provided with a guide rail provided along the vertical frame, The shielding panel body is composed of a plurality of panels arranged in a vertical direction, At least one of the shielding panels is configured to be slidable in the vertical direction along the guide rail, so that the shielding panel can be opened and closed.

[0009] As a result, when strong winds are expected, the shielding panel body can be opened to allow wind to pass through. This makes it possible to eliminate the need to dismantle and remove the soundproofing panel in the event of strong winds. In addition, since a filter member is provided at the opening, it is possible to allow wind to pass through while preventing objects larger than a certain size from passing through.

[0011] Hereinafter, a number of embodiments of the "soundproof panel" according to the present invention will be described with reference to the drawings. In the multiple embodiments, functionally and / or structurally corresponding and / or associated parts may be given the same reference numerals. For corresponding and / or associated parts, the descriptions of other embodiments may be referred to.

[0012] (First embodiment) As shown in Fig. 1, at a construction site, demolition site, civil engineering site, or other construction site, a temporary scaffolding 11 is installed around a building 10 as a construction target. At a construction site or civil engineering site, the building 10 is the target to be constructed, and at a demolition site, the building 10 is the target to be demolished.

[0013] 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.

[0014] As shown in Fig. 2, the soundproof panel 120 is provided on a side of the scaffolding 11 to cover the side of the scaffolding 11. More specifically, the soundproof panel 120 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 120 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 120 in a schematic manner, and a detailed configuration and diagrams will be described later.

[0015] 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 more susceptible to being blown by the wind. In addition, scaffolding may be installed across multiple floors depending on the height of the building, and in this case, there is a risk of the scaffolding being blown by the strong wind and collapsing. Therefore, conventionally, in the case of weather where strong winds are expected (for example, in the case of a typhoon), the soundproof panel and the scaffolding were once dismantled and removed, which was very troublesome. Therefore, in this embodiment, the soundproof panel 120 is configured as follows. A detailed description will be given below. Note that FIG. 3 is a front view of the soundproof panel 120 when viewed from the outside (so-called front side), and FIG. 4 is a back view of the soundproof panel 120 when viewed from the side of the building 10 (the side of the scaffolding 11) (so-called back side).

[0016] 3 and 4, the soundproof panel 120 includes a rectangular frame body 130, a panel body 140 serving as a shielding panel body covering the inside of the frame body 130, and a ventilation panel 170 serving as a filter member. The soundproof panel 120 is configured symmetrically.

[0017] First, the frame body 130 will be described. As shown in Fig. 3, the frame body 130 has a pair of vertical frames 31 and a pair of horizontal frames 132, and has a rectangular shape in which the horizontal frames 132 are longer than the vertical frames 131. The soundproof panel 120 is usually arranged so that the vertical frames 131 are aligned along the up-down direction and the horizontal frames 132 are aligned along the left-right direction (horizontal direction). In other words, the vertical frames 131 are arranged on both the left and right sides, and the horizontal frames 132 are arranged on the top and bottom sides. In this embodiment, the depth direction is a direction perpendicular to the soundproof panel 120, and the side of the building 10 corresponds to the inside in the depth direction, and the side opposite the building 10 corresponds to the outside in the depth direction.

[0018] Next, the panel body 140 will be described. As shown in FIG. 4, the panel body 140 is provided symmetrically. The panel body 140 has a so-called louver structure and includes a plurality of blades 141 as long boards. The blades 141 are formed in a long and narrow plate shape so as to extend in the left-right direction along the horizontal frame 132. The blades 141 are formed from the right end of the horizontal frame 132 to almost the left end. The blades 141 are arranged in a plurality of tiers in the vertical direction. At this time, the blades 141 are arranged so as to be parallel to each other.

[0019] As shown in FIG. 5, each slat 141 is rotatably supported by a rotating shaft 142. The rotating shaft 142 is provided to extend in the left-right direction and is inserted through the upper end of each slat 141. Both ends of the rotating shaft 142 are fixed to the vertical frame 131. Each slat 141 is configured to be rotatable about the rotating shaft 142 such that its lower end protrudes toward the building 10 (see the solid arrow in FIG. 5(a)). Each slat 141 is configured such that its inclination angle is fixed about the rotating shaft 142 until its lower end becomes horizontal. In this embodiment, as shown in FIG. 5(b), when each slat 141 becomes horizontal, its inclination angle is fixed.

[0020] Since the rotating shaft 142 is inserted through the upper end of each slat 141, when the lower end of each slat 141 protrudes towards the building 10, the amount of protrusion of each slat 141 in the depth direction is greater on the building 10 side than on the opposite side of the building 10. In other words, when each slat 141 is in a horizontal position, the distance L11 from the rotating shaft 142 to the lower end of each slat 141 in the depth direction (vertical direction of the soundproof panel 120) is greater than the distance L12 from the rotating shaft 142 to the upper end of each slat 141.

[0021] 5(a), when each slat 141 is closed, i.e., when the lower end does not protrude, the lower end of each slat 141 is overlapped with the upper end of the slat 141 located below. In other words, each slat 141 overlaps with the lower slat 141 without any gaps, in a state where it is slightly inclined in the up-down direction. At that time, the lower end of each slat 141 is positioned closer to the building 10 than the upper end of the lower slat 141.

[0022] 4, soundproof panel 120 includes tilt mechanisms 180 that tilt each of blades 141 in conjunction with one another around each rotation shaft 142. Tilt mechanisms 180 are provided on both the left and right ends of each blade 141. Tilt mechanism 180 includes rod-shaped tilt rod 181 that extends in the vertical direction, and fixing mechanism 182 for fixing tilt rod 181.

[0023] As shown in FIG. 4, both corners at the lower end of each slat 141 are rotatably fixed to the tilt rod 181. By drawing out the tilt rod 181 toward the building 10, each slat 141 can be tilted in conjunction with each other around each rotation shaft 142. The fixing mechanism 182 is provided on the upper part of the tilt rod 181 and is configured to fix the tilt rod 181 when each slat 141 is drawn out and placed in a horizontal position. This allows the tilt mechanism 180 to fix the inclination angle of each slat 141 when it is placed in a horizontal position. This allows each slat 141 to be fixed in a horizontal position and the panel body 140 to be opened.

[0024] Next, the ventilation panel 170 will be described. As shown in Fig. 3, the ventilation panel 170 is made of a punched metal in which a plurality of circular holes 171 are formed in a certain pattern so as to allow air to pass through while preventing the passage of objects having a size greater than a predetermined size (for example, objects greater than or equal to 5 cm). In this embodiment, the plurality of circular holes 171 are formed in a plurality of rows.

[0025] The ventilation panel 170 is fixed to the frame body 130 so as to cover the entire inner area surrounded by the frame body 130. When the soundproof panel 120 is installed on the side of the scaffolding 11, the ventilation panel 170 is fixed to the outside of the frame body 130 so as to be disposed on the outside of the soundproof panel 120 (the opposite side to the building 10) (see FIG. 5). This makes it possible for the ventilation panel 170 to pass wind passing through the opening of the panel body 140 when the panel body 140 is opened, while preventing an object having a size equal to or larger from passing to the outside of the soundproof panel 120 even if the object passes through the opening. The opening of the panel body 140 corresponds to a gap between the blades 141 and the blades 141 when the panel body 140 is opened. An object having a size equal to or larger than a predetermined size that passes through the opening of the panel body 40 is, for example, a long tool or a rod-shaped steel frame.

[0026] The panel body 140 is disposed closer to the building 10 than the ventilation panel 170. The distance in the depth direction between the panel body 140 and the ventilation panel 170 when closed, more specifically, the distance from the rotation shaft 142 to the ventilation panel 170, is configured to be longer than the distance L12 from the rotation shaft 142 to the upper end of each slat 141 when each slat 141 is in a horizontal state (i.e., when opened). In other words, the panel body 140 and the ventilation panel 170 are spaced apart so that each slat 141 does not interfere with the ventilation panel 170 when each slat 141 is opened.

[0027] The effects of the first embodiment will be described.

[0028] The panel body 140 is configured to be openable and closable by rotating each of the blades 141. Meanwhile, a ventilation panel 170 that allows air to pass through but does not allow objects having a predetermined size or larger to pass through is fixed to the outside of the frame body 130. Therefore, even if an object having a predetermined size or larger passes through the opening of the panel body 140 when the panel body 140 is opened, the ventilation panel 170 can prevent the object from flying out (or falling) to the outside.

[0029] The soundproof panel 120 includes a tilt mechanism 180 that tilts each of the blades 141 in conjunction with each other around each rotation shaft 142, and the panel body 140 is configured to be openable and closable by changing the tilt angle of each blade 141 by the tilt mechanism 180. Therefore, it is not necessary to rotate the blades 141 one by one, and the panel body 140 can be easily opened.

[0030] When the panel body 140 is opened, each slat 141 is configured to be inclined so as to protrude toward the building 10. When the panel body 140 is opened, the amount of protrusion of each slat 141 in the vertical direction of the panel body 140 is greater on the building 10 side than on the opposite side of the building 10. This makes it possible to shorten the distance separating the panel body 140 and the ventilation panel 170. Therefore, it is possible to form the soundproof panel 120 thin when closed.

[0031] When the panel body 140 is opened, the inclination angle of each blade 141 is fixed until it becomes horizontal. That is, each blade 141 is not inclined until its lower end is above its upper end where the rotation shaft 142 is located. This makes it possible to prevent dust and the like from scattering through the opening and ventilation panel 170 when the panel body 140 is opened. For example, it is possible to prevent dust and the like attached to each blade 141 from sliding down and scattering due to the inclination of the blade 141 when the panel body 140 is opened.

[0032] When the panel body 140 is closed, the lower end of each slat 141 is overlapped with the upper end of the slat 141 located below, and at that time, the lower end of each slat 141 is disposed closer to the building 10 than the lower slat 141. As a result, the opening direction of the gaps between the slats 141 faces downward on the building 10 side (inside). Therefore, as shown by the dashed arrow in FIG. 5(a), dust and the like generated from the construction site hits the panel body 140 and falls inward according to the inclination of each slat 141. In other words, when dust and the like hits the panel body 140 and falls, it is possible to prevent it from passing through the gaps between the slats 141 and falling to the outside of the panel body 140.

[0033] Second embodiment A soundproof panel 20 of a second embodiment in which a part of the configuration of the soundproof panel 120 in the first embodiment is modified will be described. The soundproof panel 20 of the second embodiment is installed on the side of the scaffolding 11, as in the first embodiment. The configuration of the soundproof panel 20 will be described with reference to Figs. 6 to 13. Fig. 6 is a front view of the soundproof panel 20 of the second embodiment as viewed from the outside (the so-called front side), and Fig. 7 is a rear view of the soundproof panel 20 of the second embodiment as viewed from the building 10 side (the scaffolding 11 side) (the so-called back side).

[0034] As shown in Figures 6 and 7, the soundproof panel 20 comprises a rectangular frame body 30, a panel body 40 covering the inside of the frame body 30, a guide rail 50 (see Figure 7) attached to the frame body 30, and a ventilation panel 70.

[0035] First, the frame body 30 will be described. 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 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.

[0036] 7 and 9, 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 Fig. 9, 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-right end portions of the vertical frame 31 towards the building 10, and the tip portion on the building 10 side in the depth direction is formed so as to bend inward in the left-right direction.

[0037] 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. 9.

[0038] Next, the panel body 40 will be described. As shown in Fig. 7, 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.

[0039] At this time, as shown in Fig. 9(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. 6, 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.

[0040] 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. 9(a), the auxiliary panel 43 is integrally formed with the vertical frame 31 with 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. As shown in FIG. 6, the upper horizontal frame 32 is integrally formed with 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.

[0041] 7 and 8, 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 vertical 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 the panel is closed.

[0042] An upper reinforcing member 44 extending straight in the left-right direction is provided above the upper panel 41. As shown in Fig. 9(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. 10, the upper reinforcing member 44 is made of a metal material and has an L-shaped cross section, with its lower end portion formed to protrude to the inside in the depth direction (towards the building 10).

[0043] Similarly, as shown in Fig. 8, 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. 11, 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, etc.

[0044] 7 and 9, 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, the locking mechanism 46 is fixed via bolts 44a to the underside of the lower end that protrudes toward the building 10 in the depth direction.

[0045] As shown in Fig. 12, 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. 9(a). This allows the upper panel 41 to be engaged with the frame body 30, restricting sliding movement.

[0046] 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.

[0047] 13, 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.

[0048] Next, a configuration for sliding the upper panel 41 will be described. As shown in FIG. 8, 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. 8, the inner rails 47 are formed so as to extend in the vertical direction, and as shown in FIG. 9(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.

[0049] As shown in Fig. 9(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 from 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.

[0050] 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. 9(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.

[0051] 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.

[0052] Next, the ventilation panel 70 will be described. As shown in Fig. 6, the ventilation panel 70 of the second embodiment is made of a punched metal in which a plurality of circular holes 71 are formed in a certain pattern so as to allow air to pass through while preventing the passage of objects having a size greater than a predetermined size (for example, objects greater than or equal to 5 cm). In this embodiment, the plurality of circular holes 71 are formed in a plurality of rows.

[0053] As shown in Fig. 6 and Fig. 9(c), the ventilation panel 70 is fixed to the vertical frame 31 with screws or the like on the outside of the frame body 30. That is, the ventilation panel 70 is fixed to the outside (opposite side of the building 10) of the upper panel 41 in the depth direction. The ventilation panel 70 is provided so as to cover the area between the auxiliary panel 43 and the lower panel 42 in the up-down direction. The ventilation panel 70 is also provided from one end of the frame body 30 to the other end in the left-right direction (that is, from the left vertical frame 31 to the right vertical frame 31). That is, the ventilation panel 70 is provided so as to cover the opening of the upper panel 41 when it is opened.

[0054] The effects of the second embodiment will be described.

[0055] The ventilation panel 70 is provided so as to cover the opening when the upper panel 41 is opened. As a result, when the panel body 40 is open, the ventilation panel 70 allows wind to pass through the opening of the panel body 40, while preventing an object having a predetermined size or larger from passing through the opening to the outside of the soundproof panel 20.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] When the panel body 40 is configured to slide up and down, 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. 14(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, the dust and the like may scatter to the outside when the upper panel 41 is opened. 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 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.

[0060] 14(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 through the gap between the lower panel 42 and the upper panel 41.

[0061] 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.

[0062] (Modification) 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.

[0063] In the above embodiment, the frame body 30, 130 may be provided with a pillar member extending in the vertical direction so as to connect the horizontal frame 32, 132 on the upper side and the horizontal frame 32, 132 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, 130 in the horizontal direction. This pillar member is for reinforcing the frame body 30, 130. When a pillar member is provided, the panel body 40, 140 may be divided into left and right parts, and the lock mechanism 46 and the tilt mechanism 180 may be provided on both the left and right sides of the divided panel body 40, 140.

[0064] In the above embodiment, the holes 71, 171 of the ventilation panels 70, 170 may be configured to be openable and closable. For example, two ventilation panels 70, 170 each having a plurality of holes 71, 171 formed in the same manner may be stacked on top of each other and slid in a predetermined direction (such as up-down or left-right), thereby allowing the holes 71, 171 of the ventilation panels 70, 170 to be openable and closable.

[0065] In the above embodiment, a net may be used instead of the ventilation panel 170, 70 as a filter member that allows air to pass while blocking objects having a size larger than a certain level. In this case, too, the soundproof panel 20, 120 can be transported as a unit by fixing the net to the frame 30, 130. Therefore, compared to the conventional case where a separate net is installed, there is no need to install the net on-site, and there is no risk of objects falling through a gap between the soundproof panel and the net.

[0066] In the above embodiment, the ventilation panel 70,170 may be disposed closer to the building 10 than the panel body 40,140.

[0067] In the first embodiment, the configuration of the tilt mechanism 180 may be changed as desired. The tilt mechanism 180 may be an electric tilt mechanism.

[0068] In the first embodiment, the tilt mechanism 180 does not have to be provided. Each blade 141 may be configured to be able to tilt independently.

[0069] In the first embodiment, the inclination angle of each blade 141 when opened may be changed as desired. Also, as long as no gap is formed between the upper blade 141 and the blade 141 below it when closed, the inclination angle of each blade 141 when closed may be changed as desired. For example, each blade 141 when closed may be straight in the up-down direction.

[0070] In the above first embodiment, each slat 141 rotates so that its lower end protrudes toward the building 10 when opened, but it may also rotate so that its lower end protrudes outward (to the opposite side of the building 10).

[0071] In the first embodiment, if the gap between the blades 141 when open does not allow an object of a certain size or larger to pass through, the ventilation panel 170 may be omitted.

[0072] In the first embodiment described above, when closed, the lower end of each blade 141 was overlapped with the upper end of the blade 141 located below it, but they do not have to be overlapped as long as no gaps are formed.

[0073] In the above first embodiment, when closed, the lower end of each slat 141 was positioned on the side of the building 10 relative to the slat 141 below it, but it may also be positioned on the outside (the opposite side of the building 10).

[0074] In the first embodiment, the blades 141 may be arranged in multiple rows in the left-right direction.

[0075] In the second embodiment, as shown in FIG. 15, 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 prevent sound, dust, and the like from leaking to the outside from 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 will rub against the unevenness formed on the lower panel 42 and be easily damaged.

[0076] 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.

[0077] In the second embodiment, the upper panel 41 is in line contact with the guide rail 50 via the inner rail 47. However, 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 peripheral surface of the inner rail 47, a protrusion may be provided on the inner peripheral 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.

[0078] In the second 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 of the upper panel 41 via the guide rails 50.

[0079] In the second embodiment, both the upper panel 41 and the lower panel 42 may be configured to be slidable.

[0080] In the second 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 panel, a middle panel, and a 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 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.

[0081] In the second 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.

[0082] In the second embodiment, as long as the panel body 40 is configured to be openable and closable, the configuration may be changed as desired. For example, the panel body 40 may be arranged in the left-right direction and configured to be slidable in the left-right direction. Also, it does not have to be a sliding type, and may be, for example, a hinged door type or a folding door type.

[0083] In the above embodiment, the soundproofing panels 20, 120 are not limited to the side surfaces of the scaffolding 11, and may be used to surround a building (construction target). For example, the soundproofing panels 20, 120 may be used as temporary enclosure panels to surround the building 10 at a construction site. [Explanation of symbols]
