Description

The present invention relates to soundproof panels installed at construction sites, demolition sites, etc.

Conventionally, at construction sites such as construction sites and demolition sites, construction work is carried out by setting up scaffolding. At that time, the sides of the scaffolding are generally covered with sheets or soundproof panels to prevent dust and noise generated from the construction site from escaping as much as possible.

By the way, when a typhoon or the like passes through, the soundproof panels installed on the sides of the scaffold receive loads from the strong winds from the side. This effect is particularly noticeable in high places such as buildings. For this reason, when strong winds are expected, it is necessary to take countermeasures against the strong winds, such as temporarily removing soundproof panels.

Therefore, in Patent Document 1, a soundproof panel covering the side surface is configured to be openable and closable. This allowed wind to pass through the open gaps in the soundproof panels, reducing the load caused by the wind.

JP 2021-110108 Publication

However, when the soundproof panel is completely opened, there is a high possibility that objects such as tools may fall through the opening.

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

A first means for solving the above problem is a soundproof panel that is installed on the side of a scaffold placed around a construction object at a construction site, covers the side of the scaffold, and has a vertical frame that extends at least in the vertical direction. and a shielding panel that covers an area surrounded by the frame, and the shielding panel is configured by stacking a plurality of panel bodies, and each of the panel bodies are each provided with a ventilation hole, and at least one of the plurality of panel bodies is a slide panel that can be slid in the vertical direction according to the vertical frame, and the slide panel is placed in a first position. When the slide panels are slid, the ventilation holes of the respective panel bodies overlap, while when the slide panels are slid to a second position different from the first position, the respective panel bodies overlap each other. The gist is that the ventilation holes in the body are blocked.

With this, when strong winds are expected, the wind can pass through by sliding the panel body and overlapping the ventilation holes. Therefore, in the case of strong winds, it is possible to save the effort of temporarily disassembling and removing the soundproof panel. Furthermore, by adjusting the size of the ventilation holes, it is possible to allow wind to pass through while preventing objects larger than a predetermined size from passing through.

A second means for solving the above problem is a soundproof panel that is installed on the side of a scaffold placed around a construction object at a construction site, covers the side of the scaffold, and has a horizontal frame that extends at least horizontally. and a shielding panel that covers an area surrounded by the frame, and the shielding panel includes an inner panel disposed on the scaffolding side and an outer panel disposed on the opposite side to the scaffolding side. The outer panel is a slide panel that can be slid in the horizontal direction according to the horizontal frame, and the inner panel and the outer panel are each provided with ventilation. a hole is provided, and when the outer panel is slid to a first position, the ventilation holes of the inner panel and the outer panel overlap, while the outer panel is moved to a second position different from the first position. The gist is that when the device is slid, mutual ventilation holes are closed by the inner panel and the outer panel.

This allows the wind to pass through if strong winds are expected by sliding the outer panel and overlapping the ventilation holes. Therefore, in the case of strong winds, it is possible to save the effort of temporarily disassembling and removing the soundproof panel. Furthermore, by adjusting the size of the ventilation holes, it is possible to allow wind to pass through while preventing objects larger than a predetermined size from passing through.

EMBODIMENT OF THE INVENTION Hereinafter, embodiments embodying the "soundproof panel" according to the present invention will be described with reference to the drawings.

As shown in FIG. 1, temporary scaffolding 11 is installed around a building 10 at a construction site, a demolition site, a civil engineering work site, or the like. The building 10 that is a construction target is a construction target in the case of a construction site or a civil engineering work site, and a demolition target in the case of a demolition site.

This scaffold 11 has a well-known configuration, and includes, for example, a plurality of vertical supports 12, a horizontal scaffold pipe 13 fixed between the vertical supports 12, a scaffold board 14 attached to the horizontal scaffold pipe 13, etc. Be prepared.

As shown in FIG. 2, the soundproof panel 20 is provided on the side surface of the scaffold 11 and covers the side surface of the scaffold 11. More specifically, the soundproof panel 20 is provided on the side of the scaffold 11 opposite to the building 10, and covers the side of the scaffold 11 to prevent dust such as fine concrete powder generated from the construction site, This prevents noise from leaking outside. The soundproof panel 20 also has the role of suppressing objects other than dust (tools, etc.) from falling and workers from falling. Note that FIG. 2 schematically shows the soundproof panel 20, and detailed configurations and diagrams will be described later.

By the way, in the past, soundproof panels have been expected to play a role in suppressing dust and noise from leaking outside, and naturally do not allow wind to pass through them. Therefore, when strong winds blow, the wind load is applied to the soundproof panels, making them susceptible to being blown away by the wind. Further, depending on the height of the building, scaffolding may be installed over multiple floors, 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, resulting in a great deal of effort. Therefore, in this embodiment, the soundproof panel 20 was configured as follows. This will be explained in detail below.

3 is a front view of the soundproof panel 20 when viewed from the outside (the so-called front side), and FIG. 4 is a front view of the soundproof panel 20 when viewed from the inside (the side of the building 10 or the scaffold 11) (the so-called back side). ) is a rear view of the soundproof panel 20 in FIG. In the present embodiment, the depth direction is a direction perpendicular to the soundproof panel 20, with the side of the building 10 corresponding to the inside in the depth direction, and the side opposite to the building 10 corresponding to the outside in the depth direction. Equivalent to.

As shown in FIGS. 3 and 4, the soundproof panel 20 includes a rectangular frame 30 and a shielding panel 40 that covers the inside of the frame 30. The shielding panel 40 is configured by stacking a plurality of panel bodies, and in this embodiment, it is composed of two panels: an inner panel 41 arranged on the inside and an outer panel 42 arranged on the outside. It is composed of overlapping bodies.

First, the frame 30 will be explained. As shown in FIG. 3, the frame body 30 includes a pair of vertical frames 31 and a pair of horizontal frames 32, with the horizontal frames 32 having a longer rectangular shape than the vertical frames 31. The soundproof panel 20 is usually arranged such that the vertical frame 31 runs along the up-down direction and the horizontal frame 32 runs along the left-right direction (horizontal direction). That is, 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.

Of the pair of vertical frames 31, when viewed from the outside (front side) (in FIG. 3), the one placed on the right side is referred to as a right frame 31R, and the one placed on the left side is referred to as a left frame 31L. There are cases. Of the pair of horizontal frames 32, the one placed on the upper side may be referred to as an upper frame 32U, and the one placed on the lower side may be referred to as a lower frame 32D.

The vertical frame 31 and the horizontal frame 32 have a rail shape with a U-shaped cross section. Specifically, as shown in FIG. 5(a), the upper frame 32U includes an inner side wall 33 disposed on the inner side, an outer side wall 34 disposed on the outer side, and a bottom portion 35. Although not shown, the lower frame 32D is also similar to the upper frame 32U. Similarly, as shown in FIG. 6(a), the right frame 31R also has an inner side wall 33 disposed on the inner side, an outer side wall 34 disposed on the outer side, and a bottom portion 35. Although not shown, the same applies to the left frame 31L. The vertical frame 31 and the horizontal frame 32 are arranged so as to open inside the frame body 30, respectively. That is, the lower frame 32D is arranged so that the bottom part 35 is located below so as to open upward, and the upper frame 32U is arranged so that the bottom part 35 is located above so as to open downward. Similarly, the right frame 31R is arranged so that it opens on the left side and the bottom part 35 is located on the right side, and the left frame 31L is arranged so that it opens on the right side and the bottom part 35 is located on the left side.

The outer edge portion of the shielding panel 40 is accommodated inside these vertical frames 31 and horizontal frames 32. That is, the upper side portion of the shielding panel 40 is accommodated between the inner side wall 33 and the outer side wall 34 of the upper frame 32U, and the lower side portion of the shielding panel 40 is accommodated between the inner side wall 33 and the outer side wall 34 of the lower frame 32D. is accommodated. Similarly, the right side portion of the shielding panel 40 is accommodated between the inner side wall 33 and the outer side wall 34 of the right frame 31R, and the left side of the shielding panel 40 is housed between the inner side wall 33 and the outer side wall 34 of the left frame 31L. part is contained. Note that, as shown in FIGS. 5 and 6, the inner panel 41 and the outer panel 42 that constitute the shielding panel 40 are housed in an overlapping state.

Next, the shielding panel 40 will be explained. As shown in FIG. 4, the inner panel 41 constituting the shielding panel 40 is composed of a single rectangular plate. The inner panel 41 may be made of any material, but may be made of, for example, a thin metal plate. The inner panel 41 is fixed to the frame 30 so as to cover the entire area surrounded by the frame 30. At this time, as shown in FIGS. 5 and 6, the outer edge portions of the inner panel 41 are housed inside the vertical frame 31 and the horizontal frame 32, respectively, and are fixed to the inner side wall 33. The outer edge portion of the inner panel 41 is fixed by any fixing method such as welding, screwing, adhesion, or the like. That is, the inner panel 41 is a fixed panel that does not move relative to the frame 30.

Further, as shown in FIG. 4, the inner panel 41 is provided with a plurality of ventilation holes 41a. Although the ventilation hole 41a is a round hole, it may have any shape such as a square hole or a long hole. The ventilation holes 41a are arranged vertically and horizontally at predetermined intervals so as to form multiple rows in the vertical direction and multiple rows in the horizontal direction. In short, the inner panel 41 is a punched metal plate that is a metal plate in which holes are formed using a mold. Further, a slit 41b extending in the vertical direction is formed in the center portion of the inner panel 41.

Next, the outer panel 42 that constitutes the shielding panel 40 will be explained. As shown in FIG. 3, the outer panel 42 is composed of a single rectangular plate. The outer panel 42 may be made of any material, but may be made of, for example, a thin metal plate.

The outer panel 42 has a size that covers most of the area surrounded by the frame 30. Specifically, the dimension of the outer panel 42 in the left-right direction is the same as the dimension of the inner panel 41 in the left-right direction. Therefore, when the outer panel 42 is attached to the frame 30, a gap is not created between the outer panel 42 and the right frame 31R or the left frame 31L.

On the other hand, the vertical dimension of the outer panel 42 is shorter than the vertical dimension of the inner panel 41. Therefore, as shown in FIG. 8, when the outer panel 42 is attached to the frame 30, a gap is formed between the outer panel 42 and the upper frame 32U or the lower frame 32D. Note that FIG. 8 is a diagram when the soundproof panel 20 is viewed from the front side, and the inner panel 41 is shown by hatching.

The outer panel 42 is housed in the frame 30 so as to be slidable in the vertical direction with respect to the frame 30. That is, while the left and right outer edge portions of the outer panel 42 are accommodated inside the right frame 31R and left frame 31L, they are fixed to the right frame 31R and left frame 31L so that they can slide in the vertical direction. do not have. That is, the outer panel 42 is a slide panel that can be slid in the vertical direction with respect to the frame 30, and the right frame 31R and the left frame 31L are slide rails that hold the outer panel 42 in a slidable manner.

Further, as shown in FIGS. 4 and 7, a handle 42b is fixed approximately at the center of the outer panel 42 and stands upright from the outer panel 42. As shown in FIGS. As shown in FIG. 7, the handle 42b is formed into an L-shaped plate, with a base end fixed to the outer panel 42 and a tip end perpendicular to the outer panel 42. Specifically, as shown in FIG. 7, the tip of the handle 42b is inserted through a through hole 42c formed in the outer panel 42 from the outside to the inside. A base end portion of the handle 42b is fixed to the outer side surface of the outer panel 42. The proximal portion is secured to the outer panel 42 by any securing method such as welding, screwing, gluing, or the like.

The tip of the handle 42b projects inward through a slit 41b formed in the inner panel 41. Further, as shown in FIG. 4, the dimension of the slit 41b in the left-right direction is greater than or equal to the dimension of the handle 42b in the left-right direction. As shown in FIG. 7, the dimension of the slit 41b in the vertical direction is a predetermined distance L1 so that the handle 42b can be slid in the vertical direction by a predetermined distance L1. By grasping this handle 42b and sliding it in the vertical direction, the outer panel 42 can be easily slid from the inside of the soundproof panel 20 (scaffolding side).

Further, the outer panel 42 is provided with a plurality of ventilation holes 42a. Although the ventilation hole 42a is a round hole, it may have any shape such as a square hole or a long hole. The ventilation holes 42a are arranged vertically and horizontally at predetermined intervals so as to form multiple rows in the vertical direction and multiple rows in the horizontal direction. In short, the outer panel 42 is a punched metal plate that is a metal plate that has been punched using a mold.

The shape, number, and arrangement of the ventilation holes 42a of the outer panel 42 are determined to match the ventilation holes 41a of the inner panel 41. That is, the ventilation holes 42a of the outer panel 42 are circular holes having the same number and the same diameter as the ventilation holes 41a of the inner panel 41. Further, the number of vertical and horizontal arrays of the ventilation holes 42a of the outer panel 42 is the same as the number of vertical and horizontal arrays of the ventilation holes 41a of the inner panel 41, and the arrangement interval of the ventilation holes 42a and the arrangement interval of the ventilation holes 41a are the same. are the same.

Here, FIG. 8(a) shows a front view of the soundproof panel 20 in a state in which the outer panel 42 is slid downward and the lower side of the outer panel 42 is accommodated in the lower frame 32D. Note that in FIG. 8, the inner panel 41 is shown hatched for convenience of illustration. As shown in FIG. 8(a), when the outer panel 42 is disposed downward, the respective panels 41 and 42 close the respective ventilation holes 41a and 42a. In other words, when the lower side of the outer panel 42 is accommodated in the lower frame 32D, the ventilation holes 42a of the outer panel 42 are located on the inner side, as shown in FIGS. 5(a), 6(a), and 7(a). The ventilation hole 41a of the inner panel 41 is closed by the outer panel 42. In this embodiment, when the lower side of the outer panel 42 is accommodated in the lower frame 32D, this corresponds to the outer panel 42 being placed at the second position.

FIG. 8(b) shows a front view of the soundproof panel 20 in a state where the outer panel 42 is slid upward and the upper side of the outer panel 42 is accommodated in the upper frame 32U. As shown in FIG. 8(b), when the outer panel 42 is disposed upward, the ventilation holes 42a of the outer panel 42 and the ventilation holes 41a of the inner panel 41 are substantially aligned. As a result, as shown in FIGS. 5(b), 6(b), and 7(b), the ventilation holes 42a of the outer panel 42 and the inner panel 41 communicate with each other, penetrating the inside and outside of the shielding panel 40. That will happen. In this embodiment, when the upper side of the outer panel 42 is accommodated in the upper frame 32U, this corresponds to the outer panel 42 being placed in the first position.

Next, the usage method and effects of the soundproof panel 20 of this embodiment will be explained.

In normal times, as shown in FIG. 8(a), the outer panel 42 is slid downward so that the lower side of the outer panel 42 is accommodated in the lower frame 32D. Since all the ventilation holes 41a and 42a are thereby closed, it is possible to suppress dust, noise, etc. from leaking to the outside. Furthermore, since the sliding outer panel 42 is placed on the outside, even if a tool or worker hits it from the inside, the outer panel 42 can be prevented from shifting and opening the ventilation holes 41a and 42a. . Furthermore, since the outer panel 42 is disposed downward, it does not shift upward due to its own weight or vibration, and can prevent the ventilation holes 41a and 42a from opening.

On the other hand, in the case of weather where strong winds are expected, the outer panel 42 is slid upward, so that the upper side of the outer panel 42 is accommodated in the upper frame 32U, as shown in FIG. 8(b). As a result, as shown in FIG. 5(b), FIG. 6(b), and FIG. 7(b), the positions of the ventilation hole 42a of the outer panel 42 and the ventilation hole 41a of the inner panel 41 are almost aligned and communicate with each other. Therefore, the wind can pass through properly. Therefore, it is possible to prevent the soundproof panel 20 from falling down due to strong winds or the like.

Further, when opened, the soundproof panel 20 allows wind to pass through the ventilation holes 41a, 42a, while preventing objects larger than the ventilation holes 41a, 42a from falling to the outside. Therefore, by adjusting the sizes of the ventilation holes 41a and 42a, tools and the like can be prevented from falling to the outside even when the soundproof panel 20 is opened.

In addition, since the shielding panel 40 covers the inside of the frame 30, dust such as concrete pieces hits the shielding panel 40 and falls, and tends to accumulate under the feet of the shielding panel 40. However, the inner panel 41 is fixed to the inner side wall 33 of the frame 30, and the outer panel 42 is arranged on the outside and configured to slide vertically along the vertical frame 31. Therefore, even in a field where dust and the like are likely to occur, dust and the like do not enter the inside of the frame 30, and the frame body 30 can be smoothly slid.

Dust such as pieces of concrete fall onto the shielding panel 40 and tend to accumulate under the feet of the shielding panel 40. For this reason, if the ventilation holes 41a and 42a are provided near the lower side of the shielding panel 40, when the shielding panel 40 is opened, dust and the like accumulated under the feet are likely to scatter to the outside. Therefore, the ventilation holes 41a and 42a are arranged above the lower frame 32D by a predetermined distance L2 or more. Thereby, when the door is opened, it is possible to suppress dust and the like accumulated under the feet from scattering to the outside.

Note that since the inner panel 41 and the outer panel 42 are in close contact with each other, their frictional force prevents them from moving downward under their own weight. That is, when the outer panel 42 is moved upward, unless a predetermined force or more is applied downward to the outer panel 42, the outer panel 42 will not move downward.

- In the above embodiment, the frame 30 may be provided with a column member extending in the vertical direction so as to connect the upper frame 32U and the lower frame 32D. For example, a column member formed to extend in the vertical direction may be provided at the center of the frame 30 in the left-right direction. This column member is for reinforcing the frame 30.

- In the embodiment described above, the arrangement of the inner panel 41 and the outer panel 42 may be interchanged in the depth direction as long as they are slid in the vertical direction. That is, if it is to be slid in the vertical direction, the inner panel body may be configured to be slid in the vertical direction.

- In the above embodiment, when the outer panel 42 is slid downward, the ventilation holes 41a, 42a are opened, and when the outer panel 42 is slid upward, the ventilation holes 41a, 42a are closed. good.

- In the above embodiment, a locking mechanism may be provided to restrict movement of the outer panel 42. For example, when the soundproof panel 20 is opened (or closed), a through hole passing through the inner panel 41 and the outer panel 42 may be provided, and a bar may be inserted into the through hole to restrict vertical movement. good. According to this, it is possible to prevent the open ventilation holes 41a, 42a from unintentionally closing, and the closed ventilation holes 41a, 42a from unintentionally opening. Note that when the soundproof panel 20 is opened, the ventilation holes 41a and 42a may be used as through holes through which bolts are inserted.

- In the above embodiment, when the upper side of the outer panel 42 is housed inside the upper frame 32U, the positions of the ventilation holes 41a and 42a match, but even if the upper side of the outer panel 42 is not housed inside the upper frame 32U, They may be made to match. That is, when moved to a predetermined arbitrary first position, the positions of the ventilation holes 41a and 42a may be aligned. Similarly, when the lower side of the outer panel 42 is housed inside the lower frame 32D, the ventilation holes 41a and 42a are closed, but even if the lower side of the outer panel 42 is not housed inside the lower frame 32D, the ventilation holes 41a and 42a are closed. Good too. In other words, the ventilation holes 41a and 42a may be closed when moved to a predetermined arbitrary second position. Note that it is desirable that the first position be located above the second position.

- In the above embodiment, in order to make the sliding movement of the outer panel 42 smooth, a sliding mechanism such as a door wheel may be provided, or protrusions may be provided at both ends of the outer panel 42 in the left and right direction so that the outer panel 42 slides smoothly against the vertical frame 31. Point contact or line contact may be made.

- In the above embodiment, the shielding panel 40 may be composed of three or more panel bodies. For example, two fixed panels (corresponding to the inner panel 41 above) are arranged inside and outside in the depth direction, a slide panel (corresponding to the outer panel 42 above) is arranged between the two fixed panels, and the two fixed panels The slide panel may be sandwiched between the panels from the depth direction. In this way, even if something hits the soundproof panel 20 from the outside (front side), the slide panel sandwiched between the two fixed panels can be prevented from shifting. In other words, it is possible to prevent the open ventilation holes 41a, 42a from unintentionally closing, and the closed ventilation holes 41a, 42a from unintentionally opening.
