Description

TECHNICAL FIELD The present invention relates to a soundproof panel installed at a construction site, a demolition site, or the like.

Conventionally, at construction sites such as construction sites and demolition sites, scaffolding is installed for construction. At that time, it is common to cover the sides of the scaffolding with sheets or soundproof panels to prevent dust and noise from leaking out from the construction site as much as possible.

By the way, when a typhoon or the like passes through, the soundproof panels and the like installed on the side of the scaffold receive a load from the side due to the strong wind. In particular, the influence is conspicuous in a high place site such as a building. Therefore, when strong winds are expected, it is necessary to take measures against strong winds, such as temporarily removing soundproof panels.

Therefore, in Patent Literature 1, a soundproof panel covering the side portion is configured to be openable and closable. As a result, the wind can pass through the open gaps of the soundproof panels, and the load caused by the wind can be reduced.

However, if the soundproof panel is completely opened, there is a high possibility that objects such as tools will fall from the opening.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide a soundproof panel that does not allow objects of a predetermined size or larger to pass through even when opened.

A soundproof panel for solving the above problems is a soundproof panel provided on the side surface of a scaffold arranged around a construction target at a construction site and covering the side surface of the scaffold, comprising: a frame; and a filter member that allows air to pass through but does not allow an object having a size larger than a predetermined value to pass through, the shielding panel body being configured to be openable and closable, and the filter member being , is fixed to the frame so as to cover at least the opening formed when the shielding panel is opened.

Thereby, when a strong wind is expected, the shielding panel body can be opened to allow the wind to pass through. Therefore, in the case of strong winds, it is possible to save the trouble of temporarily dismantling and removing the soundproof panel. In addition, since the filter member is provided in the opening, it is possible to prevent passage of an object having a size larger than a predetermined value while allowing air to pass through.

Hereinafter, a plurality of embodiments embodying the "soundproof panel" according to the present invention will be described with reference to the drawings. In several embodiments, functionally and/or structurally corresponding and/or related parts may be labeled with the same reference numerals. For corresponding and/or associated parts, reference can be made to the description of other embodiments.

(First embodiment)
As shown in FIG. 1, a temporary scaffolding 11 is installed around a building 10 as a construction object at a construction site such as a construction site, demolition site, or civil engineering site. The building 10 is an object to be built in the case of a construction site or a civil engineering construction site, and an object to be demolished in the case of a demolition site.

The scaffolding 11 has a well-known configuration, and includes, for example, a plurality of vertical posts 12, horizontal scaffolding pipes 13 fixed between the vertical posts 12, scaffolding plates 14 attached to the horizontal scaffolding pipes, and the like. .

As shown in FIG. 2 , the soundproof panel 120 is provided on the side surface of the scaffolding 11 to cover the side surface of the scaffolding 11 . More specifically, the soundproof panel 120 is provided on the side of the scaffolding 11 opposite to the building 10, and covers the side of the scaffolding 11 to remove dust such as fine concrete powder from the construction site, It suppresses noise from leaking to the outside. The soundproof panel 120 also serves to prevent objects other than dust (such as tools) from falling and workers to fall. Note that FIG. 2 schematically shows the soundproof panel 120, and detailed configuration and drawings will be described later.

Conventionally, soundproof panels are expected to play a role in suppressing the leakage of dust and noise to the outside, so naturally they do not allow the passage of wind or the like. Therefore, when a strong wind blows, a wind load is applied to the soundproof panel, making it susceptible to being blown by the wind. In addition, scaffolding may be provided over multiple floors depending on the height of the building, and in this case, there is a risk that the scaffolding will collapse due to strong winds. For this reason, in the past, when strong winds were expected (for example, in the case of a typhoon), the soundproof panels and scaffolding had to be 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. 3 is a front view of the soundproof panel 120 when viewed from the outside (so-called front side), and FIG. 4 is a soundproof panel when viewed from the side of the building 10 (the side of the scaffolding 11) (so-called back side). 120 is a rear view of FIG.

As shown in FIGS. 3 and 4, the soundproof panel 120 includes a rectangular frame 130, a panel 140 as a shielding panel covering the inside of the frame 130, and a ventilation panel 170 as a filter member. And prepare. Note that the soundproof panel 120 is configured symmetrically.

First, the frame 130 will be described. As shown in FIG. 3, the frame body 130 includes a pair of vertical frames 31 and a pair of horizontal frames 132. The horizontal frames 132 are longer than the vertical frames 131 and have a rectangular shape. The soundproof panel 120 is normally arranged such that the vertical frame 131 extends vertically and the horizontal frame 132 extends horizontally (horizontally). That is, 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, the side of the building 10 corresponds to the inside in the depth direction, and the side opposite to the building 10 is the outside in the depth direction. Equivalent to.

Next, the panel body 140 will be explained. 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 plates. The wing plate 141 is formed in an elongated plate shape so as to extend in the left-right direction along the horizontal frame 132 . The wing plate 141 is formed substantially from the right end to the left end of the horizontal frame 132 . Each blade 141 is arranged side by side so as to form a plurality of stages in the vertical direction. In that case, each blade 141 is arranged so as to be parallel to each other.

Further, as shown in FIG. 5, each blade 141 is rotatably supported by a rotary shaft 142 . The rotating shaft 142 is provided so as to extend in the left-right direction, and is inserted through the upper end portion of each blade 141 . Both ends of the rotating shaft 142 are fixed to the vertical frame 131 respectively. Each blade 141 is configured to be rotatable about this rotary shaft 142 so that the lower end protrudes toward the building 10 (see the solid line arrow in FIG. 5A). Further, each wing plate 141 is configured such that the angle of inclination thereof is fixed around the rotating shaft 142 until the lower end thereof becomes horizontal. In this embodiment, as shown in FIG. 5B, the inclination angle is fixed when each blade 141 is in a horizontal state.

Since the rotary shaft 142 is inserted through the upper end of each louver 141, when the lower end of each louver 141 protrudes toward the building 10, the amount of protrusion of each louver 141 in the depth direction is There are more on the side of the building 10 than on the opposite side of the building 10. - 特許庁That is, when each louver 141 is in a horizontal state, the distance L11 from the rotating shaft 142 to the lower end of each louver 141 in the depth direction (vertical direction of the soundproof panel 120) is It is larger than the distance L12 to the upper end of 141 .

Further, as shown in FIG. 5(a), when each louver 141 is closed, that is, when the lower end does not protrude, the lower end of each louver 141 is aligned with the upper end of the lower louver 141. It is designed to be superimposed on the part. That is, each wing plate 141 overlaps the lower wing plate 141 without a gap while being slightly inclined with respect to the vertical direction. At that time, the lower end of each louver 141 is arranged closer to the building 10 than the upper end of the lower louver 141 .

As shown in FIG. 4 , the soundproof panel 120 includes a tilt mechanism 180 that tilts the blades 141 in conjunction with each other about the rotation shafts 142 . The tilt mechanisms 180 are provided at both left and right ends of each blade 141 . The tilt mechanism 180 includes a rod-shaped tilt rod 181 extending in the vertical direction and a fixing mechanism 182 for fixing the tilt rod 181 .

As shown in FIG. 4 , both corners at the lower end of each blade 141 are rotatably fixed to the tilt bar 181 . By pulling out the tilt bar 181 to the side of the building 10, it is possible to tilt each louver 141 in conjunction with each rotation shaft 142 as a center. The fixing mechanism 182 is provided above the tilt bar 181, and is configured to fix the tilt bar 181 when each blade 141 is pulled out and placed in a horizontal state. Thereby, the tilt mechanism 180 can fix the inclination angle when each blade 141 is in a horizontal state. As a result, each blade 141 can be fixed in a horizontal state and the panel body 140 can be opened.

Next, the ventilation panel 170 will be described. As shown in FIG. 3, the ventilation panel 170 has a plurality of circular holes 171 which allow air to pass through but prevent objects having a predetermined size or larger (for example, objects of 5 cm or more) from passing through. It is composed of metal punching metal formed in a pattern. In this embodiment, a plurality of circular holes 171 are formed in a plurality of rows.

This ventilation panel 170 is fixed to the frame 130 so as to cover the entire inner area surrounded by the frame 130 . In addition, 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 130 so as to be arranged outside the soundproof panel 120 (on the side opposite to the building 10). (See Figure 5). As a result, when the panel body 140 is opened, the ventilation panel 170 allows the wind passing through the opening of the panel body 140 to pass through, and even if an object having a predetermined size or larger passes through the opening, the ventilation panel 170 is soundproof. It is possible to prevent it from passing outside the panel 120 . The opening of the panel body 140 corresponds to the gap between the blades 141 when opened. An object having a size larger than a predetermined size that passes through the opening of the panel body 40 is, for example, a long tool or a rod-like steel frame.

The panel body 140 is arranged closer to the building 10 than the ventilation panel 170 is. Further, the distance in the depth direction between the panel body 140 and the ventilation panel 170 when closed, more specifically, the distance from the rotating shaft 142 to the ventilation panel 170 is the same as when each blade 141 is in a horizontal state. It is configured to be longer than the distance L12 from the rotating shaft 142 to the upper end of each blade 141 (that is, when opened). That is, the panel body 140 and the ventilation panel 170 are separated from each other so that each blade 141 does not interfere with the ventilation panel 170 when each blade 141 is opened.

Effects of the first embodiment will be described.

The panel body 140 can be opened and closed by rotating each blade 141 . On the other hand, on the outside of the frame 130, a ventilation panel 170 is fixed that allows air to pass through but does not allow objects having a size larger than a predetermined value to pass through. Therefore, when the panel body 140 is opened, even if an object having a predetermined size or larger passes through the opening of the panel body 140, the ventilation panel 170 prevents the object from jumping out. Storing (or dropping) can be prevented.

The soundproof panel 120 includes a tilt mechanism 180 that tilts each louver 141 in conjunction with each rotating shaft 142 . , is configured to be openable. Therefore, it is not necessary to rotate the blades 141 one by one, and the panel body 140 can be easily opened.

When the panel body 140 is opened, each wing plate 141 is configured to incline so as to protrude toward the building 10 side. When opened, the amount of protrusion of each wing plate 141 in the vertical direction of the panel body 140 is larger on the building 10 side than on the opposite side of the building 10 . As a result, the distance separating the panel body 140 and the ventilation panel 170 can be shortened. Therefore, it is possible to form the soundproof panel 120 thin when closed.

When the panel body 140 is opened, the inclination angle is fixed until each blade 141 becomes horizontal. That is, the lower end of each louver 141 is prevented from being inclined above the upper end where the rotating shaft 142 is located. As a result, it is possible to prevent dust and the like from scattering through the opening and the ventilation panel 170 when the door is opened. For example, it is possible to prevent dust or the like adhering to each wing plate 141 from sliding down and scattering due to the inclination of the wing plate 141 when the door is opened.

When the panel body 140 is closed, the lower end of each louver 141 overlaps the upper end of the louver 141 located on the lower side. is arranged closer to the building 10 than the As a result, the opening direction of the gaps between the blades 141 faces downward on the building 10 side (inside). Therefore, as indicated by the dashed arrows in FIG. 5A, dust and the like generated from the construction site hit the panel body 140 and fall inward along the inclination of each blade 141 . That is, when dust hits the panel body 140 and falls, it can be prevented from passing through the gaps between the blades 141 and falling outside the panel body 140 .

(Second embodiment)
A soundproof panel 20 of a second embodiment, which is obtained by partially changing the configuration of the soundproof panel 120 of the first embodiment, will be described. The soundproof panel 20 of this second embodiment is installed on the side surface of the scaffolding 11 as in the first embodiment. The structure of this soundproof panel 20 will be described with reference to FIGS. 6 to 13. FIG. FIG. 6 is a front view of the soundproof panel 20 of the second embodiment when viewed from the outside (so-called front side), and FIG. 7 is a side view of the building 10 (scaffolding 11 side) (so-called back side). 2 is a rear view of the soundproof panel 20 of the second embodiment in FIG.

As shown in FIGS. 6 and 7, the soundproof panel 20 includes a rectangular frame 30, a panel body 40 covering the inside of the frame 30, and guide rails 50 attached to the frame 30 (see FIG. 7). 7) and a ventilation panel 70.

First, the frame 30 will be explained. The frame body 30 has a pair of vertical frames 31 and a pair of horizontal frames 32, and the horizontal frames 32 are longer than the vertical frames 31 and have a rectangular shape. The soundproof panel 20 is normally arranged such that the vertical frame 31 extends vertically and the horizontal frame 32 extends horizontally (horizontally). That is, the vertical frames 31 are arranged on both left and right sides, and the horizontal frames 32 are arranged on the top and bottom sides.

As shown in FIGS. 7 and 9, the vertical frame 31 is provided with a guide rail 50 extending along the vertical frame 31 (that is, along the vertical direction). As shown in FIG. 9, the guide rail 50 has a substantially U-shaped cross section, and is formed integrally with the vertical frame 31 in this embodiment. The guide rail 50 is provided on the side surface of the vertical frame 31 on the side of the building 10 . That is, the guide rail 50 is formed so as to protrude from the lateral end of the vertical frame 31 to the side of the building 10, and the distal end on the side of the building 10 in the depth direction is bent inward in the lateral direction. is formed as

In this embodiment, the depth direction is the direction perpendicular to the soundproof panel 20, the side of the building 10 corresponds to the inside in the depth direction, and the side opposite to the building 10 is the outside in the depth direction. Equivalent to. Further, since the panel body 40 is provided symmetrically, only one side of the left and right direction is illustrated in FIG.

Next, the panel body 40 will be explained. As shown in FIG. 7, the panel body 40 is composed of a plurality of panels arranged side by side in the vertical direction. The panel body 40 of this embodiment includes an upper panel 41 and a lower panel 42 . The lower panel 42 is composed of a single rectangular plate so as not to pass dust, etc., and is fixed to the lower portion of the frame 30 so as to cover the lower half of the frame 30. As shown in FIG.

At that time, as shown in FIG. 9(b), the lower panel 42 is fixed to the outside of the frame 30 (on the side opposite to the building 10) in the depth direction by a fixing member such as a rivet. In the present embodiment, the casing frame 33 that covers the depth direction outer side and the left and right side surfaces of the left and right ends of the lower panel 42 and restricts movement in the depth direction and the left and right direction is integrated with the vertical frame 31. formed. In addition, as shown in FIG. 6, the lower horizontal frame 32 has a casing that covers the depth direction outside and the bottom surface of the bottom end portion of the bottom panel 42 and restricts movement in the depth direction and downward movement. A frame 34 is integrally formed.

Further, the panel body 40 is provided with an elongated auxiliary panel 43 above the upper panel 41 in order to fill the gap between the horizontal frame 32 on the upper side and the upper panel 41 . Like the lower panel 42, the auxiliary panel 43 is fixed to the outside of the frame 30 in the depth direction by a fixing member such as a rivet. As with the lower panel 42, as shown in FIG. 9A, the auxiliary panel 43 covers the depth direction outer side and the left and right side surfaces of the left and right ends of the auxiliary panel 43 in the depth direction. A casing frame 35 is integrally formed with the vertical frame 31 for restricting the movement of the body and the movement in the left-right direction. In addition, as shown in FIG. 6, the upper horizontal frame 32 has a casing frame 36 that covers the depth direction outer side and upper face of the lower end portion of the auxiliary panel 43 and restricts movement in the depth direction and upward direction. are integrally formed.

As shown in FIGS. 7 and 8, the upper panel 41, like the lower panel 42, is composed of a single rectangular plate so as not to allow dust to pass through, and the upper half of the frame 30 is substantially It is constructed in a size that can be covered. The upper panel 41 is attached to the frame body 30 so as to be slidable along the vertical frame 31 (that is, along the vertical direction). A configuration for sliding movement will be described later. The shape of the lower end of the upper panel 41 is determined so that it overlaps the upper end of the lower panel 42 in the depth direction when closed.

Above the upper panel 41, an upper reinforcing member 44 extending straight in the left-right direction is provided. As shown in FIG. 9A and the like, the upper reinforcing member 44 is fixed to the inner side (back side) of the upper panel 41 in the depth direction by a fixing member such as a rivet. As shown in FIG. 10, the upper reinforcing member 44 is made of a metal material and has an L-shaped cross section. is formed in

Similarly, as shown in FIG. 8, below the upper panel 41, a lower reinforcing member 45 extending straight in the left-right direction is provided. The lower reinforcing member 45 is fixed to the inner side (back side) of the upper panel 41 in the depth direction by a fixing member such as a rivet. Further, as shown in FIG. 11, the lower reinforcing member 45 is made of a metal material and has an L-shaped cross section, and the upper end protrudes inward in the depth direction (toward the building 10). is formed as The upper reinforcing member 44 and the lower reinforcing member 45 reinforce the upper panel 41 and suppress warpage.

Further, as shown in FIGS. 7 and 9, the upper panel 41 is provided with a lock mechanism 46 on the inner side in the depth direction (on the side of the building 10) for restricting the sliding movement. The lock mechanism 46 is fixed to both left and right ends of the upper reinforcing member 44 . More specifically, both left and right ends of the upper reinforcing member 44 are fixed to the lower surface of the lower end protruding toward the building 10 in the depth direction via bolts 44a.

As shown in FIG. 12, the lock mechanism 46 has 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 laterally outward, the tip thereof can be inserted through the through hole 50a provided in the guide rail 50, as shown in FIG. 9(a). As a result, the upper panel 41 can be locked to the frame 30 and its sliding movement can be restricted.

Further, by moving the bar 46a inward in the left-right direction, the tip thereof can be pulled out from the through hole 50a. As a result, the locking is released and the upper panel 41 can be slid.

As shown in FIG. 13, by rotating the bar 46a in the direction of the arrow in a state in which the bar 46a is moved inward in the lateral direction, the bar 46a is engaged with the locking plate 46b provided inward in the lateral direction. It is possible to stop and restrict movement in the left and right direction. As a result, it is possible to prevent the bar 46a from moving outward in the left-right direction and contacting the guide rail 50 at its tip while the upper panel 41 is sliding. The structure of the lock mechanism 46 is not limited to the bar structure, and may be arbitrarily changed as long as the structure can regulate and release the sliding movement.

Next, a configuration for sliding the upper panel 41 will be described. As shown in FIG. 8, inner rails 47 are provided on both left and right sides of the upper panel 41 . The inner rail 47 is accommodated in a guide rail 50 provided on the vertical frame 31 and is configured to be vertically movable. In other words, the guide rail 50 corresponds to the outer rail for the inner rail 47 . More specifically, as shown in FIG. 8, the inner rail 47 is formed to extend vertically, and has a substantially U-shaped cross section as shown in FIG. 9(a). In addition, the outer dimension L1 of the inner rail 47 in the depth direction is substantially the same as or slightly shorter than the inner dimension of the guide rail 50 so that it can be accommodated inside the guide rail 50 . The inner rail 47 is configured to be vertically slidable with respect to the guide rail 50 .

As shown in FIG. 9A, the inner rails 47 are fixed to the left and right ends of the upper panel 41. As shown in FIG. At this time, the outer surface of the upper panel 41 is brought into contact with the inner surface of the side wall 47b on the side opposite to the building 10 (the side of the frame body 30) among the side walls 47b and 47c on both sides in the depth direction of the inner rail 47. fixed to The bottom portion 47 a (outer end portion in the left-right direction) of the inner rail 47 is arranged outside the end portion in the left-right direction of the upper panel 41 . A through hole 47d is provided at a portion of the bottom portion 47a of the inner rail 47 facing the bar 46a, and the tip of the bar 46a is configured to be movable in the left-right direction.

Also, 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 is provided with a plurality of protrusions 48 extending in the vertical direction on the outer surface facing the guide rail 50 . More specifically, as shown in FIG. 9A, in the inner rail 47, the outer surface of the bottom portion 47a (outer surface in the left-right direction) has a projection projecting outward in the left-right direction (toward the bottom of the guide rail 50). Portions 48a are provided at both ends in the depth direction.

In addition, in the inner rail 47, two protrusions 48b projecting outward in the depth direction are provided on the outer surface of the side wall 47b on the outer side in the depth direction (the side opposite to the building 10). The convex portion 48b is provided at a position separated by a predetermined distance in the left-right direction. In addition, in the inner rail 47, a convex portion 48c that protrudes inward in the depth direction is provided on the outer surface of the side wall 47c on the inner side (on the side of the building 10) in the depth direction. These projections 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 projections 48 a to 48 c of the inner rail 47 .

Next, the ventilation panel 70 will be described. As shown in FIG. 6, the ventilation panel 70 of the second embodiment, like the first embodiment, allows air to pass through, but also blocks objects having a predetermined size or larger (for example, objects of 5 cm or more). A metal punching metal having a plurality of circular holes 71 formed in a fixed pattern so as not to pass through. In this embodiment, a plurality of circular holes 71 are formed in a plurality of rows.

As shown in FIGS. 6 and 9(c), the ventilation panel 70 is fixed to the vertical frame 31 on the outside of the frame 30 with screws or the like. That is, the ventilation panel 70 is fixed outside the upper panel 41 in the depth direction (opposite side of the building 10). The ventilation panel 70 is provided so as to cover the area between the auxiliary panel 43 and the lower panel 42 in the vertical direction. In addition, the ventilation panel 70 is provided from end to end of the frame 30 (ie, from the left vertical frame 31 to the right vertical frame 31) in the left-right direction. That is, the ventilation panel 70 is provided so as to cover the opening when the upper panel 41 is opened.

Effects of the second embodiment will be described.

A ventilation panel 70 is provided to cover the opening of the upper panel 41 when it is opened. As a result, when the panel body 40 is opened, the ventilation panel 70 allows the air passing through the opening of the panel body 40 to pass through, and even if an object having a predetermined size or larger passes through the opening, the ventilation panel 70 can provide soundproofing. It becomes possible to prevent it from passing outside the panel 20 .

The upper panel 41 of the panel body 40 is configured to be vertically slidable along the guide rails 50, so that the soundproof panel 20 can be opened and closed. Thereby, when a strong wind is expected, the upper panel 41 can be opened to allow the wind to pass. Therefore, in the case of strong wind, it is possible to save the trouble of temporarily dismantling and removing the soundproof panel 20 .

By the way, since the panel body 40 covers the inside of the frame body 30 , dust such as concrete pieces hits the panel body 40 and falls, and tends to accumulate under the panel body 40 . However, since the guide rail 50 is provided so as to extend vertically along the vertical frame 31, it is difficult for dust and the like to accumulate on the guide rail 50. As shown in FIG. Therefore, the soundproof panel 20 of the present embodiment, in which the upper panel 41 is vertically slidable along the guide rail 50, can be slidably moved even in a site where dust is likely to occur.

Dust such as concrete pieces hits the panel body 40 and falls, and tends to accumulate at the feet of the panel body 40 . Therefore, if the lower panel 42 is configured to be openable, there is a possibility that dust and the like accumulated under the feet will scatter outside when the lower panel 42 is opened. In addition, it may be difficult to open the lower panel 42 because a lump such as a piece of concrete or an object such as a tool leans against the foot of the panel body 40 . Therefore, in this embodiment, the upper panel 41 is configured to be slidable. As a result, it is possible to suppress scattering of dust or the like accumulated under the feet to the outside. Moreover, even when an object is leaning against the panel body 40, the soundproof panel 20 can be easily opened.

When the panel body 40 is configured to slide vertically, 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. Here, as shown in FIG. 14A, when the lower panel 42 is arranged closer to the building 10 than the upper panel 41 (inner side in the depth direction), the construction site is located on the upper side of the lower panel 42. There is a risk that dust or the like from the empty space will accumulate, and in this case, there is a possibility that it will scatter outside when the upper panel 41 is opened. Further, when closed, the gap between the lower panel 42 and the upper panel 41 opens upward on the inner side of the soundproof panel 20 and opens downward on the outer side of the soundproof panel 20. There is also a possibility that dust or the like may scatter to the outside from the gap between the panel 42 and the upper panel 41 as indicated by the arrow.

Therefore, in the present embodiment, as shown in FIG. 14B, the upper panel 41 is arranged closer to the building 10 (inner side in the depth direction) than the lower panel 42 is. As a result, since the lower panel 42 is located outside the upper panel 41 (on the side opposite to the building 10), dust and the like are dropped to the feet of the upper panel 41 (see arrow), and the lower panel 42 is removed. It is possible to prevent dust and the like from accumulating on the upper portion. Also, it is possible to prevent dust and the like from scattering outside through the gap between the lower panel 42 and the upper panel 41 .

Also, the upper panel 41 is in line contact with the guide rail 50 via the inner rail 47 . As a result, even if dust or the like adheres to the guide rail 50, it is easier to slide than in the case of surface contact.

(Modification)
- In the above embodiment, the frame 30 has a rectangular shape, but it may have a square shape. Further, the frame body 30 may have a rectangular shape elongated in the vertical direction.

- In the above-described embodiment, the frame members 30 and 130 may be provided with vertically extending column members so as to connect the horizontal frames 32 and 132 on the upper side and the horizontal frames 32 and 132 on the lower side. For example, a column member extending vertically may be provided in the center of the frames 30 and 130 in the left-right direction. This column member is for reinforcing the frames 30 and 130 . When the column members are provided, the panel bodies 40 and 140 may be divided into left and right sides, and the lock mechanism 46 and the tilt mechanism 180 may be provided on both left and right sides of the divided panel bodies 40 and 140 .

- In the above embodiment, the holes 71, 171 of the ventilation panels 70, 170 may be configured to be openable. For example, by stacking two ventilation panels 70 and 170 in which a plurality of holes 71 and 171 are similarly formed and sliding them in a predetermined direction (vertical direction or horizontal direction), the holes 71 and 170 of the ventilation panels 70 and 170 are opened. 171 may be configured to be openable.

- In the above-described embodiment, a net may be employed instead of the ventilation panels 170 and 70 as a filter member that allows air to pass through but does not allow objects having a predetermined size or larger to pass through. In this case also, by fixing the net to the frames 30 and 130, the soundproof panels 20 and 120 can be transported. Therefore, compared to the conventional case of installing a separate net, there is no need to install the net at the site, and there is no possibility of things falling due to a gap between the soundproof panel and the net.

- In the above embodiment, the ventilation panels 70 and 170 may be arranged closer to the building 10 than the panel bodies 40 and 140 .

- In the first embodiment, the configuration of the tilt mechanism 180 may be changed arbitrarily. An electric tilt mechanism 180 may be used.

- In the first embodiment, the tilt mechanism 180 may not be provided. Each blade 141 may be tilted separately.

- In the above-described first embodiment, the angle of inclination of each blade 141 at the time of opening may be changed arbitrarily. Moreover, if a gap cannot be formed between the upper louver 141 and the lower louver 141 when closed, the inclination angle of each louver 141 when closed may be changed arbitrarily. For example, each blade 141 when closed may be straightened in the vertical direction.

- In the above-described first embodiment, each wing plate 141 rotates so that its lower end protrudes toward the building 10 when opened. You may rotate so that it may protrude.

- In the above-described first embodiment, the ventilation panel 170 may be omitted if the gaps between the blades 141 when opened do not allow objects of a predetermined size or larger to pass through.

In the first embodiment, the lower end of each blade 141 is overlapped with the upper end of the lower blade 141 when closed. It doesn't have to be.

- In the first embodiment, the lower end of each louver 141 was arranged closer to the building 10 than the lower louver 141 at the time of closing. side).

- In the said 1st Embodiment, each wing board 141 may be arranged side by side by multiple rows in the left-right direction.

- 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 inside the upper end portion of the lower panel 42 so as to extend in the width direction (horizontal direction), which is the direction in which the lower panel 42 extends. The seal member 99 is always in contact with the outside of the upper panel 41, and is in contact with the lower end of the upper panel 41 when the panel body 40 is closed. As a result, leakage of sound, dust, etc. to the outside through the gap between the upper panel 41 and the lower panel 42 can be suppressed. The reason why the sealing member 99 is fixed to the lower panel 42 is that the inner surface of the lower panel 42 may be uneven due to the adhesion of dust and the like. This is because the member 99 rubs against the irregularities formed on the lower panel 42 and is easily damaged.

Further, for example, the upper reinforcing member 44 and the lower reinforcing member 45 are fixed to the outside of the upper panel 41 (on the side opposite to the building 10), and the protruding portions of the upper reinforcing member 44 and the lower reinforcing member 45 in the depth direction , the gap may be closed. In this case, it is preferable that the projecting portion of the lower reinforcing member 45 is arranged between the upper panel 41 and the lower panel 42 when the upper panel 41 is closed. Moreover, it is preferable that the projecting portion of the upper reinforcing member 44 is arranged between the upper panel 41 and the auxiliary panel 43 when the upper panel 41 is closed. Needless to say, the length of the projecting portion in the depth direction is adjusted according to the separation distance between the upper panel 41 and the lower panel 42 so as to fit in the gap. With this configuration, 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 are filled by the protruding portions of the upper reinforcing member 44 and the lower reinforcing member 45 in the depth direction. It can be preferably closed.

- In the second embodiment, the upper panel 41 is in line contact with the guide rail 50 via the inner rail 47, but the upper panel 41 and the guide rail 50 are configured to be in point contact or line contact. If so, the configuration may be changed arbitrarily. 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 . Moreover, although the convex portion 48 is formed to extend along the vertical direction, instead of this, a plurality of projection portions may be arranged on a straight line along the vertical direction. In the present specification, the term "point contact" does not mean perfect point contact, but means that the opposing surfaces of the guide rail 50 and the inner rail 47 are not in wide surface contact, but are in local contact. do. The same is true for line contact.

- 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 may be omitted. For example, the upper panel 41 may be configured such that both left and right sides thereof are slid by the guide rails 50 .

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

- In the second embodiment, the auxiliary panel 43 may be omitted. Also, the panel body 40 may be composed of three or more sheets. For example, the panel body 40 may be composed of three panels, upper, middle and lower, so that the middle panel can be slidably moved. 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 feet of the soundproof panel 20, the panel in the middle can be opened to the upper side without being affected. In this case, when the guide rail 50 is closed, the guide rail 50 is positioned outside the middle panel. You can open the middle panel.

- In the above second embodiment, the lower panel 42 may be arranged closer to the building 10 than the upper panel 41 . Also, the lower panel 42 may be configured to be slidable.

- In the above-described second embodiment, if the panel body 40 is configured to be openable and closable, the configuration may be arbitrarily changed. For example, the panel bodies 40 may be arranged in the left-right direction so as to be slidable in the left-right direction. Moreover, it does not have to be a sliding type, and may be, for example, a hinged door type or a folding door type.
