Description

The present invention relates to soundproofing panels that are installed at construction sites, demolition sites, etc.

Traditionally, at construction sites, demolition sites, and other construction sites, scaffolding is set up 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.

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 pronounced at high-altitude construction sites such as buildings. For this reason, when strong winds are predicted, it has become necessary to take measures against strong winds, such as temporarily removing soundproofing panels.

Therefore, in Patent Document 1, the soundproofing panels covering the side sections are configured to be openable and closable. This allows wind to pass through the gaps in the open soundproofing panels, reducing the load caused by the wind.

JP 2021-110108 A

However, opening the soundproofing panels completely increases the risk of objects, such as tools, falling through the openings.

The present invention was made in consideration of the above problems, and its purpose is to provide a soundproofing panel that does not allow objects larger than a certain size to pass through even when open.

The first means for solving the above problem is a soundproofing panel that is provided on the side of scaffolding that is placed around a construction object at a construction site and covers the side of the scaffolding, and includes a frame body having a vertical frame extending at least in the vertical direction, and a shielding panel that covers the area surrounded by the frame body, and the shielding panel is composed of multiple panel bodies stacked on top of each other, each of which has a ventilation hole, and at least one of the multiple panel bodies is a sliding panel that can slide up and down along the vertical frame, and when the sliding panel is slid to a first position, the ventilation holes of each of the panel bodies overlap, while when the sliding panel is slid to a second position different from the first position, the ventilation holes of each of the panel bodies are blocked by each other's panel bodies.

As a result, when strong winds are predicted, the panel body can be slid to overlap the ventilation holes to allow wind to pass through. This eliminates the need to dismantle and remove the soundproof panel in the event of strong winds. Also, by adjusting the size of the ventilation holes, it is possible to allow wind to pass through while preventing objects larger than a certain size from passing through.

The second means for solving the above problem is a soundproofing panel that is provided on the side of scaffolding that is placed around a construction object at a construction site and covers the side of the scaffolding, and includes a frame body having a horizontal frame that extends at least horizontally, and a shielding panel that covers the area surrounded by the frame body, and the shielding panel is composed of an inner panel that is placed on the scaffolding side and an outer panel that is placed on the outside opposite the scaffolding side, which are stacked together, and the outer panel is a sliding panel that can slide horizontally along the horizontal frame, and the inner panel and the outer panel each have a ventilation hole, and when the outer panel is slid to a first position, the ventilation holes of the inner panel and the outer panel overlap, while when the outer panel is slid to a second position different from the first position, the ventilation holes of the inner panel and the outer panel are blocked by each other.

As a result, when strong winds are expected, the outer panel can be slid to overlap the ventilation holes to allow wind to pass through. This eliminates the need to dismantle and remove the soundproofing panel in the event of strong winds. Also, by adjusting the size of the ventilation holes, it is possible to allow wind to pass through while preventing objects larger than a certain size from passing through.

FIG. 4A is a front view of a soundproof panel when closed, and FIG. 4B is a front view of the soundproof panel when open.

The following describes an embodiment of the "soundproof panel" of the present invention with reference to the drawings.

As shown in FIG. 1, at a construction site, demolition site, civil engineering site, or other construction site, temporary scaffolding 11 is set up around a building 10. The building 10, which is the construction object, is an object to be constructed at a construction site or civil engineering site, and is an object to be demolished at a demolition site.

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

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

Conventionally, soundproofing panels are expected to prevent dust and noise from leaking to the outside, and so naturally do not allow wind to pass through. For this reason, when a strong wind blows, the wind load is applied to the soundproofing panel, making it more susceptible to being blown around by the wind. Depending on the height of the building, scaffolding may be installed across multiple floors, in which case there is a risk of the building collapsing due to being blown around by strong winds. For this reason, conventionally, when strong winds are expected in weather conditions (e.g., in the case of a typhoon), the soundproofing panels and scaffolding have had to be dismantled and removed, which was very time-consuming. Therefore, in this embodiment, the soundproofing panel 20 is constructed as follows. This will be explained in detail below.

Note that Fig. 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 rear view of the soundproof panel 20 when viewed from the inside (the building 10 side or the scaffolding 11 side) (the so-called back side). In this embodiment, the depth direction is the 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.

As shown in Figures 3 and 4, the soundproof panel 20 includes a rectangular frame body 30 and a shielding panel 40 that covers the inside of the frame body 30. The shielding panel 40 is made up of a plurality of overlapping panel bodies, and in this embodiment, it is made up of two overlapping panel bodies, an inner panel 41 that is disposed on the inside and an outer panel 42 that is disposed on the outside.

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

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

The vertical frame 31 and the horizontal frame 32 have a rail shape with a U-shaped cross section. In detail, as shown in FIG. 5(a), the upper frame 32U has an inner side wall 33 arranged on the inside, an outer side wall 34 arranged on the outside, and a bottom 35. Although not shown, the lower frame 32D is similar to the upper frame 32U. Similarly, as shown in FIG. 6(a), the right frame 31R also has an inner side wall 33 arranged on the inside, an outer side wall 34 arranged on the outside, and a bottom 35. Although not shown, the left frame 31L is similar. And the vertical frame 31 and the horizontal frame 32 are each arranged so as to open on the inside of the frame body 30. In other words, the lower frame 32D is arranged so that the bottom 35 is located below so as to open upward, and the upper frame 32U is arranged so that the bottom 35 is located above so as to open downward. Similarly, the right frame 31R is positioned so that the bottom 35 is located on the right side so that it opens to the left, and the left frame 31L is positioned so that the bottom 35 is located on the left side so that it opens to the right.

The outer edge portion of the shielding panel 40 is housed inside these vertical frames 31 and horizontal frames 32. That is, the upper edge portion of the shielding panel 40 is housed between the inner side wall 33 and the outer side wall 34 of the upper frame 32U, and the lower edge portion of the shielding panel 40 is housed between the inner side wall 33 and the outer side wall 34 of the lower frame 32D. Similarly, the right edge portion of the shielding panel 40 is housed between the inner side wall 33 and the outer side wall 34 of the right frame 31R, and the left edge portion of the shielding panel 40 is housed between the inner side wall 33 and the outer side wall 34 of the left frame 31L. As shown in Figures 5 and 6, the inner panel 41 and the outer panel 42 that make up the shielding panel 40 are housed in a stacked state.

Next, the shielding panel 40 will be described. As shown in FIG. 4, the inner panel 41 constituting the shielding panel 40 is composed of a single rectangular plate. The material of the inner panel 41 is arbitrary, but for example, it is composed of a thin metal plate. The inner panel 41 is fixed to the frame body 30 so as to cover the entire area surrounded by the frame body 30. In this case, as shown in FIG. 5 and FIG. 6, the outer edge portion of the inner panel 41 is housed inside the vertical frame 31 and the horizontal frame 32, respectively, and is 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, or adhesive. In other words, the inner panel 41 is a fixed panel that does not move relative to the frame body 30.

As shown in FIG. 4, the inner panel 41 is provided with a number of ventilation holes 41a. The ventilation holes 41a are round, but may be any shape, such as rectangular or elongated. The ventilation holes 41a are aligned vertically and horizontally at a predetermined interval 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, which is a metal plate that has been punched using a die. Also, a slit 41b extending vertically is formed in the center of the inner panel 41.

Next, the outer panel 42 constituting the shielding panel 40 will be described. As shown in FIG. 3, the outer panel 42 is composed of a single rectangular plate. The material of the outer panel 42 is arbitrary, but it is composed of a thin metal plate, for example.

The outer panel 42 is large enough to cover most of the area surrounded by the frame body 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 body 30, no gap is formed 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 body 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 view of the soundproof panel 20 as seen from the front side, and the inner panel 41 is shown hatched.

The outer panel 42 is housed in the frame body 30 so as to be able to slide up and down relative to the frame body 30. In other words, the left and right outer edge portions of the outer panel 42 are housed inside the right frame 31R and the left frame 31L, but are not fixed to the right frame 31R and the left frame 31L so as to be able to slide up and down. In other words, the outer panel 42 is a slide panel that is able to slide up and down relative to the frame body 30, and the right frame 31R and the left frame 31L are slide rails that hold the outer panel 42 so that it can slide up and down.

As shown in Figs. 4 and 7, a handle 42b is fixed to the outer panel 42 at approximately the center thereof. As shown in Fig. 7, the handle 42b is formed in an L-shaped plate shape, with its base end fixed to the outer panel 42 and its tip perpendicular to the outer panel 42. In more detail, as shown in Fig. 7, the tip of the handle 42b is inserted from the outside to the inside of the outer panel 42 through a through hole 42c formed in the outer panel 42. The base end of the handle 42b is fixed to the outer side surface of the outer panel 42. The base end is fixed to the outer panel 42 by any fixing method such as welding, screwing, or adhesive.

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

The outer panel 42 is also provided with multiple ventilation holes 42a. The ventilation holes 42a are round, but may be any shape, such as rectangular or elongated. The ventilation holes 42a are aligned vertically and horizontally at a predetermined interval 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, which is a metal plate that has been processed to have holes punched using a die.

The shape, number, and arrangement of the ventilation holes 42a in the outer panel 42 are determined so as to match the ventilation holes 41a in the inner panel 41. In other words, the ventilation holes 42a in the outer panel 42 are the same in number as the ventilation holes 41a in the inner panel 41, and are round holes of the same diameter. Furthermore, the number of ventilation holes 42a arranged vertically and horizontally in the outer panel 42 is the same as the number of ventilation holes 41a arranged vertically and horizontally in the inner panel 41, and the arrangement interval of the ventilation holes 42a is the same as the arrangement interval of the ventilation holes 41a.

8(a) shows a front view of the soundproof panel 20 in a state where the outer panel 42 is slid downward and the lower edge of the outer panel 42 is housed in the lower frame 32D. In FIG. 8, the inner panel 41 is hatched for convenience of illustration. As shown in FIG. 8(a), when the outer panel 42 is disposed downward, the ventilation holes 41a, 42a of each panel are blocked by the respective panels 41, 42. In other words, when the lower edge of the outer panel 42 is housed in the lower frame 32D, the ventilation holes 42a of the outer panel 42 are blocked by the inner panel 41, and the ventilation holes 41a of the inner panel 41 are blocked by the outer panel 42, as shown in FIG. 5(a), FIG. 6(a), and FIG. 7(a). In this embodiment, when the lower edge of the outer panel 42 is housed in the lower frame 32D, this corresponds to the outer panel 42 being disposed in the second position.

Figure 8(b) shows a front view of the soundproof panel 20 with the outer panel 42 slid upward and the upper edge of the outer panel 42 housed in the upper frame 32U. As shown in Figure 8(b), when the outer panel 42 is positioned upward, the positions of the ventilation holes 42a of the outer panel 42 and the ventilation holes 41a of the inner panel 41 are approximately aligned. As a result, as shown in Figures 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 and penetrate the inside and outside of the shielding panel 40. In this embodiment, when the upper edge of the outer panel 42 is housed in the upper frame 32U, this corresponds to the outer panel 42 being disposed in the first position.

Next, we will explain how to use and the effects of the soundproof panel 20 of this embodiment.

Under normal circumstances, as shown in FIG. 8(a), the outer panel 42 is slid downward so that the lower edge of the outer panel 42 is housed in the lower frame 32D. This blocks all ventilation holes 41a, 42a, preventing dust, noise, and the like from leaking to the outside. In addition, because the sliding outer panel 42 is positioned on the outside, even if a tool or worker bumps into it from the inside, the outer panel 42 is prevented from shifting and opening the ventilation holes 41a, 42a. In addition, because the outer panel 42 is positioned downward, it will not shift upward due to its own weight or vibration, preventing the ventilation holes 41a, 42a from opening.

On the other hand, when strong winds are expected, the outer panel 42 is slid upward as shown in FIG. 8(b) so that the upper edge of the outer panel 42 is housed in the upper frame 32U. As a result, as shown in FIG. 5(b), FIG. 6(b), and FIG. 7(b), the positions of the ventilation holes 42a of the outer panel 42 and the ventilation holes 41a of the inner panel 41 are approximately aligned and communicate with each other, allowing wind to pass through optimally. This prevents the soundproof panel 20 from collapsing due to strong winds, etc.

When open, the soundproof panel 20 allows air 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 size of the ventilation holes 41a, 42a, tools and other objects can be prevented from falling to the outside even when the soundproof panel 20 is open.

In addition, because the shielding panel 40 covers the inside of the frame body 30, dust and dirt such as concrete pieces tend to hit the shielding panel 40, fall off, and accumulate under the shielding panel 40. However, the inner panel 41 is fixed to the inner side wall 33 of the frame body 30, and the outer panel 42 is arranged on the outside and is configured to slide up and down along the vertical frame 31. Therefore, even in sites where dust and dirt are likely to be generated, dust and dirt do not get inside the frame body 30, and it can be slid appropriately.

Dust such as concrete fragments hit the shielding panel 40 and fall, apt to accumulate under the shielding panel 40. For this reason, if ventilation holes 41a, 42a are provided near the bottom edge of the shielding panel 40, dust and other debris that has accumulated under the panel's feet will easily scatter to the outside when the panel is open. Therefore, the ventilation holes 41a, 42a are positioned above the lower frame 32D by a predetermined distance L2 or more. This makes it possible to prevent dust and other debris that has accumulated under the panel's feet from scattering to the outside when the panel is open.

In addition, because the inner panel 41 and the outer panel 42 are in close contact with each other, the frictional force prevents them from moving downward under their own weight. In other words, when the outer panel 42 is moved upward, it will not move downward unless a downward force of a predetermined magnitude or more is applied to the outer panel 42.

(Modification)
In the above embodiment, the frame 30 is rectangular, but it may be square. Also, the frame 30 may be rectangular in shape and be elongated in the vertical direction.

- In the above embodiment, if the outer panel 42 is configured to be slidable, it may be slidable in the left-right direction.

- In the above embodiment, the number and arrangement of the handles 42b may be changed as desired. The shape may also be changed as desired.

- In the above embodiment, the frame body 30 may be provided with a pillar member extending in the vertical direction to connect the upper frame 32U and the lower frame 32D. For example, a pillar member formed to extend in the vertical direction may be provided in the center of the frame body 30 in the left-right direction. This pillar member is intended to reinforce the frame body 30.

- In the above embodiment, if the panel is to be slid up and down, the positions of the inner panel 41 and the outer panel 42 may be interchanged in the depth direction. In other words, if the panel is to be slid up and down, the inner panel body may be configured to be slid up and down.

- In the above embodiment, the ventilation holes 41a, 42a may be opened when the outer panel 42 is slid downward, and may be configured to be closed when the outer panel 42 is slid upward.

- 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 open (or closed), a through hole may be provided through the inner panel 41 and the outer panel 42, and a latch may be inserted into the through hole to restrict movement in the vertical direction. This prevents the open ventilation holes 41a, 42a from closing unintentionally, and prevents the closed ventilation holes 41a, 42a from opening unintentionally. When the soundproof panel 20 is open, the ventilation holes 41a, 42a may be used as the through hole through which the latch is inserted.

- In the above embodiment, when the upper edge of the outer panel 42 is housed inside the upper frame 32U, the positions of the ventilation holes 41a, 42a are aligned, but they may be aligned even if they are not housed inside the upper frame 32U. In other words, when the panel is moved to a predetermined arbitrary first position, the positions of the ventilation holes 41a, 42a may be aligned. Similarly, when the lower edge of the outer panel 42 is housed inside the lower frame 32D, the ventilation holes 41a, 42a are blocked, but they may be blocked even if they are not housed inside the lower frame 32D. In other words, when the panel is moved to a predetermined arbitrary second position, the ventilation holes 41a, 42a may be blocked. It is preferable that the first position is higher than the second position.

- In the above embodiment, a sliding mechanism such as a wheel may be provided to allow the outer panel 42 to slide smoothly, or protrusions may be provided on both left and right ends of the outer panel 42 to make point or line contact with the vertical frame 31.

- 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 described above) may be arranged on the inside and outside in the depth direction, and a sliding panel (corresponding to the outer panel 42 described above) may be arranged between the two fixed panels, with the sliding panel being sandwiched between the two fixed panels from the depth direction. In this way, even if something hits the soundproof panel 20 from the outside (front side), the sliding 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.
