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 Document 1, a soundproof panel (protective panel in Patent Document 1) 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.

Japanese Patent Application Laid-Open No. 2021-110108

By the way, in the soundproof panel of Patent Document 1, the soundproof panel is opened and closed by horizontally sliding along the rail. However, dust and the like generated from the work site hits the soundproof panel on the side and falls, and tends to accumulate on the rails under the feet. In addition, when dust or the like accumulates on the rail, it becomes difficult to slide. In particular, in the case of a demolition site, a large amount of dust such as fine concrete powder may be generated, and this tendency is conspicuous.

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 can be easily opened and closed.

A soundproof panel for solving the above problems is a soundproof panel provided on the side surface of a scaffold arranged around a construction object at a construction site to cover the side surface of the scaffold, and has a vertical frame extending at least in the vertical direction. A frame body, a panel body covering the inside of the frame body, and a guide rail provided along the vertical frame, wherein the panel body is composed of a plurality of sheets and arranged side by side in the vertical direction. At least one of the panel bodies is configured to be vertically slidable along the guide rail, so that the panel body can be opened and closed.

Thereby, when a strong wind is expected, the 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.

Moreover, since the guide rail is provided so as to extend in the vertical direction along the vertical frame, it is difficult for dust and the like to accumulate on the guide rail. Therefore, by configuring a part of the panel body to slide vertically along the guide rail, it is possible to suitably prevent difficulty in sliding movement even in a site where dust is likely to occur.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment which actualized the "soundproof panel" concerning this invention is described, referring drawings.

(First embodiment)
As shown in FIG. 1, a temporary scaffolding 11 is installed around a building 10 at a construction site such as a construction site, demolition site, or civil engineering site. The building 10, which is a construction object, 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 13, and the like. Prepare.

As shown in FIG. 2 , the soundproof panel 20 is provided on the side surface of the scaffolding 11 to cover the side surface of the scaffolding 11 . More specifically, the soundproof panel 20 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 20 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 20, 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 20 is configured as follows. A detailed description will be given below. 3 is a front view of the soundproof panel 20 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). 20 is a rear view of FIG.

As shown in FIGS. 3 and 4, the soundproof panel 20 includes a rectangular frame 30, a panel 40 covering the inside of the frame 30, and guide rails 50 attached to the frame 30 (see FIG. 4). 6) and

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. 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. 4 and 6, 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. 6, 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 toward the building 10 side (inward in the depth direction) from the left and right end portions of the vertical frame 31 , and the end portions on the side of the building 10 in the depth direction It is formed so as to bend inward in the direction.

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. Also, since the panel body 40 is provided symmetrically, only one side of the left and right direction is shown in FIG.

Next, the panel body 40 will be explained. As shown in FIGS. 3 and 4, 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. 6(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. Further, as shown in FIG. 3, the lower horizontal frame 32 has a casing that covers the outer side and lower surface of the lower end of the lower panel 42 in the depth direction and restricts the movement in the depth direction and the downward direction. 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. 6A, 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. Further, as shown in FIG. 4, 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. 3 and 4, 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.

As shown in FIG. 5, an upper reinforcement member 44 is provided above the upper panel 41 and extends straight in the left-right direction. As shown in FIG. 6A and the like, the upper reinforcing member 44 is fixed to the inside (rear side) of the upper panel 41 in the depth direction by a fixing member such as a rivet. Further, as shown in FIG. 7, the upper reinforcing member 44 is made of a metal material and has an L-shaped cross section, and the lower end thereof protrudes inward in the depth direction (toward the building 10). is formed in

Similarly, as shown in FIG. 5, 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. As shown in FIG. 8, the lower reinforcing member 45 is made of a metal material and has an L-shaped cross section. 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. 4 and 6, the upper panel 41 is provided with a lock mechanism 46 for restricting sliding movement on the inner side in the depth direction (on the side of the building 10). 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. 9, 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. 6(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. 10, 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 a 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. Further, the configuration of the lock mechanism 46 is not limited to the bar structure, and may be arbitrarily changed as long as the configuration can regulate and release the sliding movement.

Next, a configuration for sliding the upper panel 41 will be described. As shown in FIG. 5, 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. 5, the inner rail 47 is formed to extend vertically, and has a substantially U-shaped cross section as shown in FIG. 6(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. 6A, the inner rails 47 are fixed to the left and right ends of the upper panel 41 . 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. 6(a), 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 .

Effects of the present embodiment will be described.

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. 11A, when the lower panel 42 is arranged on the building 10 side (inner side in the depth direction) than the upper panel 41, the upper side of the lower panel 42 is a construction site. 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. 11B, the upper panel 41 is arranged closer to the building 10 (inside 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, as shown in FIG. 12, a seal member 99 may be provided in the gap between the upper panel 41 and the lower panel 42 to close the gap. The seal member 99 is fixed 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 above embodiment, the upper panel 41 is in line contact with the guide rail 50 via the inner rail 47. However, if the upper panel 41 and the guide rail 50 are configured to be in point contact or line contact, For example, 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 above embodiment, the upper panel 41 is configured to slide relative to the guide rails 50 via the inner rails 47, but the inner rails 47 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 above embodiment, both the upper panel 41 and the lower panel 42 may be configured to be slidable.

- In the above 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 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 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 30 may be provided with a column member extending vertically so as to connect the horizontal frame 32 on the upper side and the horizontal frame 32 on the lower side. For example, a column member extending vertically may be provided at the center of the frame 30 in the left-right direction. This column member is for reinforcing the frame 30 . When the column member is provided, the panel body 40 may be divided into left and right, and the lock mechanism 46 and the like may be provided on both the left and right sides of the divided panel body 40 .

(Second embodiment)
In the above-described embodiment, a frame reinforcing member that reinforces the frame 30 may be provided. A second embodiment describing a frame reinforcing member will be described below with reference to FIGS. 13 to 16. FIG. The second embodiment will be described with reference to the soundproof panel 20 of the first embodiment. In addition, about the structure similar to 1st Embodiment, the same code|symbol is attached|subjected and description is abbreviate|omitted.

As described in the first embodiment, the frame 30 has a pair of vertical frames 31 extending in the vertical direction and a pair of horizontal frames 32 extending in the horizontal direction, and is formed in a horizontally long rectangular shape. Therefore, when the upper panel 41 is slid to open the soundproof panel 20, the shape of the open portion needs to be maintained only by the frame 30, and depending on the strength of the frame 30, it may be necessary to reinforce it.

Therefore, in the second embodiment, a frame reinforcing member 100 as shown in FIG. 13 is provided. FIG. 13 is a rear view showing the soundproof panel 20 of the second embodiment when viewed from the building 10 side. The frame reinforcing member 100 is fixed to the lateral frame 32 at both ends thereof and is formed in a bar shape extending in the vertical direction. Thereby, the frame reinforcing member 100 connects between the pair of horizontal frames 32 and reinforces the frame 30 .

Also, in the second embodiment, two frame reinforcing members 100 are provided. 13, the distance from the right vertical frame 31 to the right frame reinforcing member 100a, the distance from the right frame reinforcing member 100a to the left frame reinforcing member 100b, and the distance from the left frame reinforcing member 100b Two frame body reinforcing members 100a and 100b are arranged so that the distance to the left vertical frame 31 is substantially equal.

14 to 16, the upper reinforcing member 44 and the lower reinforcing member 45 are arranged so that the frame reinforcing member 100 does not interfere with the upper reinforcing member 44 and the lower reinforcing member 45, which are panel reinforcing members. are provided with recesses 144 and 145 at intersections with the frame reinforcing member 100, respectively. The recesses 144 and 145 are provided so as to open inward in the depth direction, and part or all of the frame reinforcing member 100 is arranged in the recesses 144 and 145 .

The frame reinforcing member 100 is formed in a rod shape along the vertical direction. Therefore, even if the upper panel 41 is slid, the recesses 144 and 145 prevent the upper reinforcing member 44 and the lower reinforcing member 45 from interfering with the frame reinforcing member 100 .

Further, the frame reinforcing member 100 is arranged between the guide rails 50 in the depth direction and has a thickness that does not protrude from the guide rails 50 . That is, as shown in FIG. 15, the frame reinforcing member 100 is arranged inside the upper panel 41 (and the lower panel 42) in the depth direction, and arranged parallel to the upper panel 41 so as not to interfere with it. there is Further, the frame reinforcing member 100 is arranged outside the inner end portion 150 of the guide rail 50 in the depth direction so as not to protrude inside the inner end portion 150 of the guide rail 50 . That is, when the soundproof panels 20 are stacked, the frame reinforcing member 100 is prevented from interfering with the other soundproof panels 20 . 15 is a cross-sectional view taken along line CC of FIG.

By providing the frame reinforcing member 100 as in the second embodiment, it is possible to prevent the frame 30 from being distorted even when the upper panel 41 is slid and opened.

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

Here, increasing the thickness of the soundproof panel 20 is undesirable in terms of handling and installation environment. On the other hand, especially the frame reinforcing member 100 is an important element in terms of strength of the soundproof panel 20 as a whole. Therefore, recesses 144 and 145 are formed in the upper reinforcing member 44 and the lower reinforcing member 45, and part or all of the frame reinforcing member 100 is arranged in the recesses 144 and 145, thereby increasing the strength of the soundproof panel 20 as a whole. An increase in the thickness of the soundproof panel 20 can be suppressed without dropping it.

(Modification of the second embodiment)
- In the said 2nd Embodiment, the frame reinforcement member 100 may be provided so that between the vertical frames 31 of a left-right pair may be connected. That is, the frame reinforcing member 100 may be formed in the shape of a bar extending in the left-right direction with both ends fixed to the vertical frame 31 .

Also, the frame reinforcing member 100 may be provided so as to connect the vertical frame 31 and the horizontal frame 32 . That is, the frame reinforcing member 100 may have one end fixed to the vertical frame 31 and the other end fixed to the horizontal frame 32, and may be formed in a bar shape extending in an oblique direction.

Further, the frame reinforcing member 100 may be provided in a brace shape. That is, it may be formed in a bar shape along the diagonal line of the frame 30 .

- In the above-described second embodiment, the frame reinforcing member 100 is formed in a bar shape. You may change the shape arbitrarily. For example, it may be provided in the shape of an elongated thin plate.
