Description

[Technical field]

[0001] The present invention relates to a panel and a support. [Background technology]

[0002] Conventionally, a wall structure has been proposed in which, for example, a support and a panel are combined (see Patent Document 1). The wall structure described in Patent Document 1 has H-shaped steel as a support. In detail, the wall structure described in Patent Document 1 is a wall structure that is installed by inserting an edge of a panel into a groove of a support (H-shaped steel) having a groove formed along the up-down direction. At the edge of the panel inserted into the groove of the H-shaped steel, a spring metal fitting is provided on a surface (front surface of the panel) that faces the flange of the H-shaped steel. This spring metal fitting is biased so as to be pressed against the flange that faces the front surface of the panel. Since this wall structure is configured with the spring metal fitting, contact between the H-shaped steel and the panel is suppressed, and deterioration of the panel is suppressed, even if the panel is subjected to vibration due to wind or the like.

[0003] [Patent Document 1] JP 2015-59337 A Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, as a support for a wall structure, a pair of channel steels having a groove defined by a bottom wall and a pair of side walls may be arranged with the bottom walls facing each other, and the pair of channel steels may be joined by a connecting member (e.g., a bolt and a nut) that penetrates the bottom wall. In such a support, the connecting member protrudes from the surface of the bottom wall within the groove. A panel is attached to the support by lowering it vertically downward with both edges inserted into the grooves of the pair of channel steels that constitute the support. When lowering the panel, it is difficult to move the panel stably, and the edge of the panel may come into contact with the connecting member protruding from the surface of the bottom wall. In this case, the connecting member that connects the pair of channel steels may be damaged.

[0010] It is also preferable that the spring device elastically presses against the side wall so as to suppress movement of the panel in a thickness direction of the panel.

[0011] It is also preferable that the panel has a lifting hanging piece protruding from the upper end surface of the panel, and an insertion recess provided on the lower end surface of the panel into which the hanging piece of the panel located in the tier directly below can be inserted when the panels are stacked one above the other.

[0018] Hereinafter, a panel according to an embodiment of the present invention will be described with reference to the drawings. Note that the embodiment described below is merely an example, and the panel of the present invention is not limited to the embodiment described below.

[0019] In this specification, the terms "perpendicular to A" and similar expressions do not only refer to a direction completely perpendicular to A, but also refer to a direction that is approximately perpendicular to A. In this specification, the terms "parallel to B" and similar expressions do not only refer to a direction that is completely parallel to B, but also refer to a direction that is approximately parallel to B. In this specification, the terms "C-shape" and similar expressions do not only refer to a perfect C-shape, but also refer to a shape that visually resembles a C-shape (approximately a C-shape).

[0020] Fig. 1 is a front view showing an example of a configuration of a panel according to an embodiment of the present invention. Fig. 2 is a front view showing an example of a state in which a wall structure is constructed by inserting the panel shown in Fig. 1 into a groove of a support. Fig. 3 is a plan view showing an example of a wall structure constructed using the panel shown in Fig. 1.

[0021] In this specification and the drawings, the direction H represents the horizontal direction, and the direction V represents the vertical direction. The direction FB represents the thickness direction of the panel 1, the arrow F represents the front side direction of the panel 1, and the arrow B represents the back side direction of the panel 1. The direction LR represents the width direction of the panel 1, the arrow L represents one side direction in the width direction of the panel 1, and the arrow R represents the other side direction in the width direction of the panel 1. The width direction LR is a direction perpendicular to the front-back direction FB in a horizontal plane. The one end side direction L is the left direction when looking from the front side to the back side of the panel 1. The other end side direction R is the right direction when looking from the front side to the back side of the panel 1. In this specification and the drawings, the "vertical direction" also includes a direction slightly inclined with respect to the vertical direction. In this specification and the drawings, the "horizontal direction" also includes a direction slightly inclined with respect to the horizontal direction.

[0022] As shown in Figures 1 and 2, the panel 1 of this embodiment is a panel that constitutes a wall 3 in a wall structure 4 having a plurality of pillars 2 extending in a vertical direction V and a wall 3 arranged between a pair of the pillars 2 among the plurality of pillars 2.

[0023] The panel 1 in this specification is not particularly limited in its use, shape, and size as long as it is a panel constituting a wall 3 in a wall structure 4 including a plurality of columns 2 extending in a vertical direction V and a wall 3 arranged between a pair of the columns 2 among the plurality of columns 2. In this embodiment, the panel 1 is a soundproof panel constituting the soundproof wall 3 in a soundproof structure 4 (an example of a wall structure 4) including a plurality of columns 2 extending in the vertical direction and a soundproof wall 3 (an example of a wall 3) arranged between a pair of the columns 2 among the plurality of columns 2.

[0024] The panel 1 can also be applied to applications other than soundproof structures. For example, the panel 1 may be a panel constituting an exterior wall, interior wall, or partition wall of a building (exterior wall panel, interior wall panel, or partition wall panel), a panel constituting a fire wall (fireproof panel), or a panel constituting an earth retaining wall or retaining wall (earth retaining wall panel or retaining wall panel). The panel 1 has functions according to the application (for example, soundproofing function, strength resistance function, fireproofing function, earth pressure resistance function, etc.). The effects of the panel 1 when applied to a soundproof structure will be described later, but the same effects can be achieved when the panel 1 is applied to a wall structure other than a soundproof structure.

[0025] The support pillar 2 can also be used for purposes other than soundproofing. For example, the support pillar 2 may be a support pillar for supporting an exterior wall, an interior wall, or a partition wall of a building, a support pillar for supporting a fire wall, or a support pillar for supporting an earth retaining wall or a retaining wall.

[0026] Hereinafter, a case where the panel 1 is a soundproof panel (hereinafter also referred to as soundproof panel 1) will be described. In this specification, the soundproof structure 4 is a wall-like structure installed to reduce noise from a noise-generating facility. The soundproof structure 4 is installed, for example, so as to surround a noise source such as a factory, or along a noise source such as a road or a railway.

[0027] The shape and size of the soundproof structure 4 are not particularly limited, so long as the soundproof structure 4 includes a plurality of pillars 2 and a soundproof wall 3 formed of a plurality of soundproof panels 1 arranged between a pair of pillars 2 among the plurality of pillars 2.

[0028] The pillars 2 support the soundproof wall 3 formed of the soundproof panel 1. In this embodiment, as shown in FIG. 3, each of the pillars 2 is configured such that a pair of channel steels 21, each having a groove portion 213 defined by a bottom wall 211 and a pair of side walls 212, are arranged with the bottom walls 211 facing each other. As a result, one pillar 2 is configured to be approximately H-shaped when viewed from above. In each of the pillars 2, the pair of channel steels 21 are joined by a joining member 22 penetrating the bottom wall 211. In this embodiment, the pair of channel steels 21 are joined by the joining members 22 at multiple points in the vertical direction V. In each of the pillars 2, the joining member 22 protrudes from the bottom wall 211 within the groove portion 213. More specifically, the joining member 22 protrudes in the width direction LR from the surface of the bottom wall 211 extending in the thickness direction FB and the vertical direction V, as shown in FIG. 3. The joining member 22 is not particularly limited as long as it is a member capable of mechanically joining the bottom walls 211 of a pair of channel steels 21 together, and is, for example, a bolt and a nut. Note that the joining member 22 may be a joining member other than a bolt and a nut, and may be, for example, a rivet or the like.

[0029] In this embodiment, the bottom wall 211 extends in the thickness direction FB and the vertical direction V of the soundproof panel 1. That is, the bottom wall 211 is a plate-like portion (flat portion) having a surface perpendicular to the width direction LR of the soundproof panel 1, i.e., an inner surface 2111 (the surface on the groove portion 213 side) and an outer surface 2112 (the surface opposite the groove portion 213) of the bottom wall 211. The inner surface 2111 of the bottom wall 211 faces the end surface 111 of the soundproof panel 1 in the width direction LR. Moreover, the outer surfaces 2112 of the bottom walls 211 of a pair of channel steels 21 face each other in the width direction LR.

[0030] In this embodiment, the pair of side walls 212 are a pair of flange portions of the channel steel 21. One side wall 212 and the other side wall 212 are each a plate-like portion (flat portion) extending along the longitudinal direction of the channel steel 21. The pair of side walls 212 are provided parallel to each other, and extend in the width direction LR and the vertical direction V when the support 2 is installed. One side wall 212 extends from one end of the bottom wall 211 in the thickness direction FB so as to be perpendicular to the bottom wall 211. The other side wall 212 extends from the other end of the bottom wall 211 in the thickness direction FB so as to be perpendicular to the bottom wall 211.

[0031] In this embodiment, the groove portion 213 is formed by a bottom wall 211 and a pair of side walls 212 so that a cross section along a direction perpendicular to the longitudinal direction is substantially U-shaped. Note that in this embodiment, the pair of side walls 212 of the channel steel 21 are both flat plate-shaped, and do not have lip portions 214 (see FIG. 3) that protrude from free ends of the pair of side walls 212 toward the opposing side wall 212.

[0032] In this embodiment, the support 2 has a pair of channel steels 21 having the same size and shape. The support 2 may have a pair of channel steels 21 having different sizes. Specifically, the support 2 may have a pair of channel steels 21 having bottom walls 211 with different widths (lengths in the thickness direction FB), for example. In this embodiment, the bottom wall 211 has a through hole (not shown) through which the joint member 22 is inserted. The bottom plates 221 of the pair of channel steels 21 are overlapped with each other so that the through holes of the pair of channel steels 21 are overlapped with each other, and the joint member 22 is inserted into the through hole. In this embodiment, one end of the joint member protrudes from the bottom wall 211 in the groove portion 213 of one of the pair of channel steels 21. In addition, the other end of the joint member protrudes from the bottom wall 211 in the groove portion 213 of the other of the pair of channel steels 21.

[0033] Specifically, when the joining members 22 are bolts and nuts, the head of the bolt protrudes from the bottom wall 211 in the groove portion 213 of one of the pair of channel steels 21. Also, the tips of the legs of the nut and bolt protrude from the bottom wall 211 in the groove portion 213 of the other of the pair of channel steels 21. When the joining members 22 are rivets, the head of the rivet protrudes from the bottom wall 211 in the groove portion 213 of one of the pair of channel steels 21. Also, the tips of the legs of the rivet protrude in a crimped state from the bottom wall 211 in the groove portion 213 of the other of the pair of channel steels 21.

[0034] The soundproof panel 1 is configured to be supported by the pillars 2 with its edge portion 11 in the width direction LR, in which the pair of pillars 2 move apart, inserted into a groove portion 213 provided in each of the pair of pillars 2.

[0035] In this specification, the "direction in which a pair of supports 2 are spaced apart" refers to a direction in which the supports 2 arranged at a predetermined interval are connected to each other, and more specifically, a direction in which the supports 2 arranged at a predetermined interval are connected to each other along the width direction LR. In this embodiment, the edge portion 11 of the soundproof panel 1 is a portion including an end face 111 of the soundproof panel 1 in the width direction LR, an end 112 in the width direction LR of a surface 12 (hereinafter also referred to as the surface 12) of the soundproof panel 1 in the thickness direction FR of the front side, and an end (an end located on the opposite side (back surface 13 side) of the end 112 in the thickness direction FR) of a surface 13 (hereinafter also referred to as the back surface 13) of the soundproof panel 1 in the thickness direction FB of the width direction LR. In this embodiment, the end 112 of the front surface 12 of the soundproof panel 1 and the end of the back surface 13 of the soundproof panel 1 are each approximately perpendicular to the end face 111 of the soundproof panel 1. The surface 12 is the surface that is farther from the sound source to be soundproofed. The back surface is the surface closer to the sound source to be sound-insulated.

[0036] In this specification, "supported by the pillars 2 while being inserted into the grooves 213 provided in each of a pair of pillars 2" means that one edge 11 of the soundproof panel 1 in the width direction LR is inserted into the groove 213 of one of the pillars 2, and the other edge 11 of the soundproof panel 1 in the width direction LR is inserted into the groove 213 of the other pillar 2, and is supported by both pillars 2.

[0037] The soundproof panel 1 is equipped with a spring device 5 that prevents contact between the edge 11 of the soundproof panel 1 and the connecting member 22 protruding from the bottom wall 211 of the channel steel 21 when the soundproof panel 1 is inserted into the groove portion 213 of the support 2.

[0038] In this specification, "the soundproof panel 1 is inserted into the groove portion 213 of the support 2" means that when the soundproof structure 4 is constructed, the edge portion 11 of the soundproof panel 1 is inserted into the groove portion 213 from the upper end portion of the support 2, as described below.

[0039] In this embodiment, as shown in FIG. 3, the soundproof panel 1 includes a panel body 10 and a spring device 5. The panel body 10 is a panel having a soundproofing function. The shape and structure of the panel body 10 are not particularly limited as long as it has a predetermined soundproofing function. In this embodiment, the panel body 10 is formed into a substantially rectangular plate shape in which the length in the width direction LR is longer than the length in the vertical direction V, as shown in FIG. 1 and FIG. 2. In this embodiment, the panel body 10 includes a frame portion 101 and a soundproofing portion 102. The frame portion 101 is, for example, formed of a frame-shaped member that constitutes the outer periphery of the panel body 10. The frame-shaped member is, for example, formed by forming a tubular member having a square cross section into a ring shape so as to form a square shape along the outer periphery of the panel body 10. The frame-shaped member is, for example, formed of a metal such as iron or stainless steel. The soundproofing portion 102 is, for example, formed by forming a sound-absorbing function such as glass wool into a plate shape. The soundproofing portion 102 is fixed to the frame portion 101 so as to be fitted inside the frame portion 101. In the example shown in FIG.

[0040] The spring device 5 has a function of preventing contact between the edge portion 11 of the soundproof panel 1 and the joint member 22 protruding from the bottom wall 211. The structure of the spring device 5 is not particularly limited as long as it has such a contact prevention function. The spring device 5 may be formed of an elastic member such as a leaf spring. In addition, the position of the spring device 5 is not particularly limited as long as it has such a contact prevention function. For example, the spring device 5 may be provided on the bottom wall 211 in the groove portion 213 of the channel steel 21, or on the side wall 212 in the groove portion 213 of the channel steel 21, or on both the bottom wall 211 and the side wall 212 in the groove portion 213 of the channel steel 21. In the present embodiment, the spring device 5 is provided on the edge portion 11 of the soundproof panel 1. In the example shown in FIG. 3, the spring device 5 is attached to the frame portion 101 of the soundproof panel 1.

[0041] Fig. 4 is a front view showing an example of the configuration of a spring device in the panel shown in Fig. 1. In the example shown in Fig. 4, spring device 5 includes a fixed portion 51 and a biasing portion 52. The material of spring device 5 is not particularly limited as long as it has the above-mentioned contact prevention function, and can be made of metal, for example. Spring device 5 shown in Fig. 4 is manufactured, for example, by bending a strip-shaped metal plate into a predetermined shape.

[0042] The fixing portion 51 is a portion that is fixed to the soundproof panel 1. In the example shown in Fig. 4, the fixing portion 51 is formed in a flat plate shape. The fixing portion 51 is fixed to the edge portion 11 of the soundproof panel 1. There is no particular limitation on the method for fixing the fixing portion 51 to the soundproof panel 1, but it is fixed, for example, by known fixing means such as welding or screws. In this embodiment, the fixing portion 51 is fixed to the frame portion 101 (see Fig. 3) of the soundproof panel 1.

[0043] The biasing portion 52 is a portion that biases the edge portion 11 of the soundproof panel 1 so as to press the edge portion 11. In the example shown in FIG. 4, the biasing portion 52 includes a rising portion 521 that rises obliquely upward from the fixed portion 51 and in a direction approaching the pressing target portion of the channel steel 21 (in the present embodiment, the inner surface 2111 of the bottom wall 211), and an extending portion 522 that extends obliquely upward from the tip of the rising portion 521 and in a direction away from the pressing target portion of the channel steel 21. In the biasing portion 52, a boundary portion 523 between the rising portion 521 and the extending portion 522 is configured to elastically press the pressing target portion of the channel steel 21. When the biasing portion 52 elastically presses the pressing target portion of the channel steel 21, the biasing portion 52 elastically displaces in the direction shown by the two-dot chain line from a natural state (shown by a solid line) before pressing. This elastic deformation allows the urging portion 52 to elastically press the pressing target portion of the channel steel 21. The spring device 5 shown in FIG. 4 is fixed to the soundproof panel 1 such that the urging portion 52 is located above the fixing portion 51.

[0044] The soundproof panel 1 is configured to include the spring device 5 that prevents contact between the edge 11 of the soundproof panel 1 and the connecting member 22 protruding from the bottom wall 211 of the channel steel 21. This makes it possible to prevent contact between the edge 11 of the soundproof panel 1 (for example, the lower end or end face of the edge 11 of the soundproof panel 1) and the connecting member 22 protruding from the bottom wall 211 of the channel steel 21 when the soundproof panel 1 is inserted into the groove 213 of the support 2. Therefore, when the edge 11 of the soundproof panel 1 is inserted into the groove 213 of the support 2 formed by joining a pair of channel steels 21 with the connecting member 22, damage to the soundproof panel 1 and the connecting member 22 caused by contact between the connecting member 22 protruding from the bottom wall 211 of the channel steel 21 and the edge 11 of the soundproof panel 1 can be prevented.

[0045] Hereinafter, several examples in which the spring device 5 is disposed at different positions in the soundproof panel 1 will be described with reference to Fig. 5 to Fig. 8. Fig. 5 is a plan view showing an example of a wall structure constructed using the panel shown in Fig. 1. In Fig. 5, the head of the bolt, which is the joining member 22, is not visible due to the presence of the spring device 5 located above the head (toward the viewer in the drawing).

[0046] 5, the spring device 5 is provided on an end surface 111 of the soundproof panel 1 that faces the bottom wall 211, and the spring device 5 urges the soundproof panel 1 in a direction in which the end surface 111 of the soundproof panel 1 moves away from the bottom wall 211. In detail, a plurality of spring devices 5 are fixed to the end surface 111 of the soundproof panel 1 at predetermined intervals along the vertical direction V. In addition, a fixing portion 51 (see FIG. 4) of the spring device 5 is fixed to the end surface 111 of the soundproof panel 1. In a state in which the spring device 5 is fixed to the end surface 111 of the soundproof panel 1, the urging portion 52 is located above the fixing portion 51. Moreover, when the soundproof panel 1 is inserted into the groove 213 of the channel steel 21 and in the inserted state, the boundary portion 523 between the rising portion 521 and the extending portion 522 elastically presses the pressing target portion of the channel steel 21 (the inner surface 2111 of the bottom wall 211) in the width direction LR. The boundary portion 523 elastically presses the pressing target portion of the channel steel 21, thereby ensuring a state in which the end surface 111 of the soundproof panel 1 is separated from the bottom wall 211 of the channel steel 21 and the joining member 22. This prevents contact between the end surface 111 of the soundproof panel 1 and the joining member 22. In the example shown in FIG. 5, the spring device 5 is provided in the center of the soundproof panel 1 in the thickness direction FB, but this is not limited to this. For example, the spring device 5 may be provided at a position separated from the center of the soundproof panel 1 in the thickness direction FB by a predetermined distance in the thickness direction FB. In this case, the spring device 5 may be provided on one side and the other side in the thickness direction FB from the center of the soundproof panel 1 in the thickness direction FB. In this configuration, contact between the spring device 5 and the joining member 22 is suppressed, so that damage to the joining member 22 can be further suppressed. Note that since the spring device 5 is elastically deformable, it can reduce the impact on the joining member 22 by elastically deforming when it comes into contact with the joining member 22, so even if the spring device 5 is provided in the center of the soundproof panel 1 in the thickness direction FB, the problem of damage to the joining member 22 does not basically occur.

[0047] In the example shown in FIG. 5, the soundproof panel 1 further includes a second spring device 6 provided on the front surface 12 and / or the back surface 13 of the soundproof panel 1 at a position facing the side wall 212 of the channel steel 21. In this embodiment, the second spring device 6 has the same structure as the spring device 5. In detail, in the example shown in FIG. 5, the soundproof panel 1 further includes a second spring device 6 provided on the front surface 12 and the back surface 13 of the soundproof panel 1 at a position facing the side wall 212 of the channel steel 21. In detail, a plurality of second spring devices 6 are fixed to the front surface 12 and the back surface 13 of the soundproof panel 1 at predetermined intervals along the vertical direction V. In addition, fixing parts (not shown) of the second spring device 6 are fixed to the front surface 12 and the back surface 13 of the soundproof panel 1. In a state in which the second spring device 6 is fixed to the front surface 12 and the back surface 13 of the soundproof panel 1, respectively, the biasing part is located above the fixing part. In addition, when the soundproof panel 1 is inserted into the groove 213 of the channel steel 21 and in the inserted state, the boundary portion between the rising portion and the extending portion elastically presses the pressing target portion of the channel steel 21 (the side wall 212 of the channel steel 21) in the thickness direction FB. The boundary portion elastically presses the pressing target portion of the channel steel 21, thereby ensuring a state in which the front surface 12 and the back surface 13 of the soundproof panel 1 are separated from the side wall 212 of the channel steel 21. This suppresses movement of the channel steel 21 in the thickness direction FB, and prevents contact between the front surface 12 and the back surface 13 of the soundproof panel 1 and the channel steel 21. Note that the second spring device 6 is not necessarily required from the viewpoint of preventing contact between the end surface 111 of the soundproof panel 1 and the joining member 22. In addition, the shape and structure of the second spring device 6 may be different from those of the spring device 5.

[0048] FIG. 6 is a plan view showing another example of a wall structure constructed using the panel shown in FIG. 1. In the example shown in FIG. 6, the channel steel 21 is a lipped channel steel having a lip portion 214 that protrudes in a hook shape from the tip of a pair of side walls 212 toward the opposing side wall 212. That is, the channel steel 21 shown in FIG. 5 does not have a lip portion, but the channel steel 21 shown in FIG. 6 differs from the channel steel 21 described in FIG. 5 in that it has a lip portion 214. In the following description, the channel steel shown in FIG. 6 is also referred to as a lipped channel steel 21. The lipped channel steel 21 shown in FIG. 6 has a pair of lip portions 214 facing each other. The distance between the tip portions of the pair of lip portions 214 is approximately the same as the thickness of the soundproof panel 1 or is slightly larger than the thickness of the soundproof panel 1. Therefore, the soundproof panel 1 can be inserted between the pair of lip portions 214.

[0049] The spring device 5 is provided on surfaces 12, 13 facing the side walls 212 of the channel steel 21 at both edge portions 11 in the width direction LR of the soundproof panel 1. Note that Fig. 6 shows one edge portion 11 of the soundproof panel 1 in the width direction LR.

[0050] The spring device 5 is configured to be guided by the lip portion 214 so that the movement of the soundproof panel 1 in the width direction LR is restricted when the soundproof panel 1 is inserted into the groove portion 213 and moves in the vertical direction V. In this embodiment, a plurality of spring devices 5 are fixed to the front surface 12 and the back surface 13 of the soundproof panel 1 at a predetermined interval from each other along the vertical direction V. Furthermore, the fixing portion 51 (see FIG. 4) of the spring device 5 is fixed to the front surface 12 and the back surface 13 of the soundproof panel 1. In a state in which the spring device 5 is fixed to the front surface 12 and the back surface 13 of the soundproof panel 1, the biasing portion 52 is located above the fixing portion 51. Furthermore, when the soundproof panel 1 is inserted into the groove portion 213 of the channel steel 21 and in a state in which the soundproof panel 1 is inserted, the spring device 5 is disposed at a position such that one end portion 53 of the spring device 5 in the width direction LR is guided by the lip portion 214. This restricts the movement of the soundproof panel 1 in the width direction LR relative to the support 2. Therefore, contact between the end face 111 of the soundproof panel 1 and the joining member 22 can be prevented.

[0051] In the example shown in FIG. 6, the spring device 5 elastically presses the side wall 212 so as to suppress the movement of the soundproof panel 1 in the thickness direction FB of the soundproof panel 1. Thus, the spring device 5 functions to restrict the movement of the soundproof panel 1 in both the thickness direction FB and the width direction LR. When the soundproof panel 1 is inserted into the groove portion 213 of the channel steel 21 and in the inserted state, the boundary portion 523 between the rising portion 521 and the extending portion 522 elastically presses the portion of the channel steel 21 to be pressed. The boundary portion 523 elastically presses the portion of the channel steel 21 to be pressed, thereby ensuring a state in which the front surface 12 and the back surface 13 of the soundproof panel 1 are separated from the side wall 212 of the channel steel 21. As a result, the movement of the soundproof panel 1 in the thickness direction FB relative to the channel steel 21 is suppressed, and contact between the front surface 12 and the back surface 13 of the soundproof panel 1 and the channel steel 21 is prevented. From the viewpoint of preventing contact between the end surface 111 of the soundproof panel 1 and the joining member 22, it is not always necessary for the spring device 5 to elastically press the side wall 212.

[0052] FIG. 7 is a plan view showing another example of a wall structure constructed using the panel shown in FIG. 1. In the example shown in FIG. 7, a spring device 5 similar to the spring device 5 shown in FIG. 5 is further provided in the example shown in FIG. 6. The spring device 5 shown in FIG. 5 is provided in the center of the soundproof panel 1 in the thickness direction FB, but as shown in FIG. 7, for example, the spring device 5 may be provided at a position spaced a predetermined distance in the thickness direction FB from the center of the soundproof panel 1 in the thickness direction FB. In this case, the spring device 5 may be provided on one side and the other side in the thickness direction FB from the center of the soundproof panel 1 in the thickness direction FB. The spring device 5 is provided on the end surface 111 of the soundproof panel 1 facing the bottom wall 211, and the spring device 5 biases the soundproof panel 1 in a direction in which the end surface 111 of the soundproof panel 1 moves away from the bottom wall 211. By providing such a spring device 5, the movement of the soundproof panel 1 in the width direction LR is further restricted. Therefore, contact between the end face 111 of the soundproof panel 1 and the joining member 22 can be prevented more reliably.

[0053] Fig. 8 is a plan view showing an example of a hanging piece in the panel shown in Fig. 1. Fig. 9 is a front view of the hanging piece shown in Fig. 8. Fig. 10 is a side view of the hanging piece shown in Fig. 8. Fig. 11 is a back view showing an example of an insertion recess in the panel shown in Fig. 1.

[0054] In this embodiment, as shown in FIGS. 1, 2, and 8 to 11, the soundproof panel 1 has a hanging piece 14 and an insertion recess 15.

[0055] 8 to 10 are lifting members provided to protrude from an upper end surface 17 of the soundproof panel 1. In this embodiment, the hanging pieces 14 are engaged with, for example, a hook for a load provided at the tip of a wire of a crane when the soundproof panel 1 is lifted by a crane or the like. In this embodiment, the hanging pieces 14 are attached to the frame portion 101 of the panel body 10.

[0056] The insertion recess 15 shown in FIG. 11 is provided on the lower end surface 18 of the soundproof panel 1, and is a recess into which the hanging piece 14 of the soundproof panel 1 arranged in the immediately lower tier can be inserted when the soundproof panels 1 are stacked vertically. In FIG. 11, the state in which the hanging piece 14 is inserted into the insertion recess 15 is shown by a broken line. In this embodiment, the insertion recess 15 has a slit-shaped through hole 1011 formed in the frame portion 101 of the panel main body 10, and a slit plate 16 having a slit-shaped through hole 161. The slit plate 16 is attached to the frame portion 101 so that the through hole 161 overlaps the through hole 1011 of the frame portion 101. The slit plate 16 is a flat plate for reinforcement. The through hole 1011 and the through hole 161 are formed to have a size that allows the hanging piece 14 to be inserted. Because the soundproof panel 1 has the insertion recess 15 and the hanging piece 14, when a plurality of soundproof panels 1 are stacked, the soundproof panels 1 can stably form the soundproof wall 3. Furthermore, because the spring device 5 is provided, when the soundproof panels 1, which are heavy objects, are stacked in this manner, and movement of the soundproof panels 1 in the thickness direction FB and the width direction LR is suppressed, the hanging piece 14 can be easily inserted into the insertion recess 15, improving workability.

[0057] Next, an example of a construction method for installing a wall structure will be described with reference to Figs. 2, 3, etc. In the example shown in Figs. 2 and 3, it is assumed that an existing soundproof wall 8 is provided. Here, a case where a soundproof structure 4 according to this embodiment as shown in Fig. 6 is constructed will be described. The soundproof structure 4 is provided above the existing soundproof wall 8. The existing soundproof wall 8 includes an existing support pillar 81 made of H-shaped steel and an existing wall 82 supported by the existing support pillar 81. Note that it is possible to install wall structures other than soundproof structures (for example, an exterior wall structure, an interior wall structure, a partition wall structure, a fireproof structure, an earth retaining wall structure, a retaining wall structure, etc.) in the same procedure as the construction method for installing a soundproof structure described below.

[0058] First, in order to install the support 2, a pair of channel steels 21 are arranged with the bottom walls 211 facing each other in the width direction LR, and are joined by the joining member 22 in a state where the bottom walls 211 face each other in the width direction LR. A plurality of support columns 2 are provided at predetermined intervals according to the required configuration of the soundproof structure 4. In this embodiment, as shown in FIG. 3, a flat support plate 83 extending from the upper end of the flange portion 811 of the existing support 81 along the horizontal direction H toward the planned position of the support 2 is attached to the flange portion 811. The support plate 83 is arranged so that its thickness direction faces the extension direction of the soundproof structure 4 (arrangement direction of the plurality of support columns 2). In addition, a reinforcing plate 84 is provided at the upper end of the support plate 83, extending along the extension direction of the support plate 83 and arranged so as to be perpendicular to the support plate 83, and the reinforcing plate 84 is fixed to the support plate 83 and the flange portion 811. A pair of channel steels 21 are arranged so as to sandwich the support plate 83 from both sides and so that their longitudinal directions are aligned with the vertical direction V, and the channel steels 21 are joined to each other by joining members 22.

[0059] When the support columns 2 are installed, the soundproof panel 1 is lifted by a crane or the like so that the soundproof panel 1 fits between the pair of support columns 2, and the soundproof panel 1 is inserted from above into the groove 213 of the channel steel 21 shown in FIG. 6. During the insertion, the movement of the soundproof panel 1 in the width direction LR is suppressed by the spring device 5, so the soundproof panel 1 is lowered in a state in which contact between the soundproof panel 1 and the connecting member 22 is prevented. This eliminates the need for a person to lower the soundproof panel 1 while holding it down so that it does not come into contact with the connecting member 22, or to lower it slowly so as not to apply a large impact to the connecting member 22. This reduces the amount of manpower required to assemble the soundproof panel 1, and shortens the time required for the assembly work.

[0060] When the installation of one soundproof panel 1 is completed, the next soundproof panel 1 is lowered on top of the lowered soundproof panel 1 in the same manner. At this time, the lower hanging piece 14 is inserted into the upper insertion recess 15. As a result, a soundproof wall 3 consisting of multiple stages of soundproof panels 1 is supported by a pair of supports 2, and a soundproof structure 4 is constructed. The hanging piece 14 and the insertion recess 15 need to be aligned in the thickness direction FB and the width direction LR, but in this embodiment, since the movement of the soundproof panel 1 in the thickness direction FB and the width direction LR is restricted by the spring device 5, alignment between the hanging piece 14 and the insertion recess 15 is not required. Therefore, multiple soundproof panels 1 can be quickly stacked.

[0061] Although Figure 2 shows an embodiment in which the spring device 5 is provided on the end surface 111 of the soundproof panel 1, the soundproof panel 1 in the embodiment shown in Figure 6 can also be assembled using the same steps as described above, and the same effect can be obtained.

[0062] In the above embodiment, the soundproof panel 1 is provided with the spring device 5, but the present invention is not limited to this. Specifically, instead of the soundproof panel 1, the support 2 may be provided with the spring device 5, or both the soundproof panel 1 and the support 2 may be provided with the spring device 5. The configuration of the spring device 5 is the same as that in the case where the soundproof panel 1 is provided with the spring device 5 (see FIG. 4). Hereinafter, the case where the support 2 is provided with the spring device 5 will be described with reference to FIG. 12 and FIG. 13. FIG. 12 is a front view showing an example of how a wall structure is constructed by inserting a panel into a groove of a support provided with a spring device. FIG. 13 is a plan view showing an example of a wall structure constructed using a support provided with a spring device. In FIG. 13, the head of the bolt, which is the joining member 22, is hidden from view due to the presence of the spring device 5 located above the head (on the front side of the paper).

[0063] The pillars 2 (see Figures 12 and 13) are pillars in a soundproof structure 4 that includes a plurality of pillars 2 extending in the vertical direction and a soundproof wall 3 disposed between a pair of the pillars 2 among the plurality of pillars 2.

[0064] Each of the pillars 2 is configured with a pair of channel steels 21, each having a groove portion 213 defined by a bottom wall 211 and a pair of side walls 212, arranged with the bottom walls 211 facing each other, and the pair of channel steels 21 are joined by connecting members 22 that penetrate the bottom walls 211, and the connecting members 22 protrude from the bottom walls 211 within the groove portion 213.

[0065] The soundproof panel 1 is configured to be supported by the pillars 2 with its edge portion 11 in the width direction LR, in which the pair of pillars 2 move apart, inserted into a groove portion 213 provided in each of the pair of pillars 2.

[0066] The support pillar 2 is provided with a spring device 5 that prevents contact between the edge 11 of the soundproof panel 1 and the joint member 22 protruding from the bottom wall 211 when the soundproof panel 1 is inserted into the groove 213 of the support pillar 2.

[0067] 13, the spring device 5 is provided on the bottom wall 211 of the channel steel 21. The spring device 5 biases the soundproof panel 1 in a direction in which the end face 111 of the soundproof panel 1 that faces the bottom wall 211 moves away from the bottom wall 211.

[0068] In detail, a plurality of spring devices 5 are fixed to the bottom wall 211 of the channel steel 21 at predetermined intervals along the vertical direction V. Furthermore, a fixing portion 51 (see FIG. 4) of the spring device 5 is fixed to the bottom wall 211 of the channel steel 21. In a state in which the spring device 5 is fixed to the bottom wall 211 of the channel steel 21, the biasing portion 52 is located above the fixing portion 51. Furthermore, when the soundproof panel 1 is inserted into the groove portion 213 of the channel steel 21 and in the inserted state, a boundary portion 523 between the rising portion 521 and the extending portion 522 elastically presses the pressing target portion of the soundproof panel 1 (the end surface 111 of the soundproof panel 1) in the width direction LR. The boundary portion 523 elastically presses the pressing target portion of the soundproof panel 1, thereby ensuring a state in which the end surface 111 of the soundproof panel 1 is separated from the bottom wall 211 of the channel steel 21 and the joining member 22. This prevents contact between the end surface 111 of the soundproof panel 1 and the joining member 22. In the example shown in FIG. 13, the spring device 5 is provided at the center of the bottom wall 211 in the thickness direction FB, but this is not limited to this. For example, the spring device 5 may be provided at a position spaced a predetermined distance in the thickness direction FB from the center of the channel steel 21 in the thickness direction FB. In this case, the spring device 5 may be provided on one side and the other side in the thickness direction FB from the center of the channel steel 21 in the thickness direction FB. In this configuration, contact between the spring device 5 and the joining member 22 is suppressed, so that damage to the joining member 22 can be further suppressed. Furthermore, since the spring device 5 is elastically deformable, it can elastically deform when it comes into contact with the joining member 22, thereby mitigating the impact on the joining member 22. Therefore, even if the spring device 5 is provided in the center of the channel steel 21 in the thickness direction FB, there is basically no problem of damage to the joining member 22.

[0069] In the example shown in Figures 12 and 13, the support 2 further includes a second spring device 6 provided on the side wall 212 of the channel steel 21 at a position facing the front surface 12 and / or the back surface 13 of the soundproof panel 1.

[0070] In the example shown in Fig. 12 and Fig. 13, the second spring device 6 has the same structure as the spring device 5. A plurality of second spring devices 6 are fixed to each side wall 212 of the channel steel 21 at a predetermined interval along the vertical direction V. Furthermore, a fixing portion (not shown) of the second spring device 6 is fixed to each side wall 212 of the channel steel 21. In a state in which the second spring device 6 is fixed to each side wall 212 of the channel steel 21, the biasing portion is located above the fixing portion. Furthermore, when the soundproof panel 1 is inserted into the groove portion 213 of the channel steel 21 and in the inserted state, the boundary portion between the rising portion and the extending portion elastically presses the pressing target portion of the soundproof panel 1 (the end portion 11 of the soundproof panel 1) in the thickness direction FB. The boundary portion elastically presses the portion of the soundproof panel 1 that is to be pressed, thereby ensuring that the front surface 12 and the back surface 13 of the soundproof panel 1 are spaced apart from the side wall 212 of the channel steel 21. This suppresses movement in the thickness direction FB relative to the channel steel 21, preventing contact between the front surface 12 and the back surface 13 of the soundproof panel 1 and the channel steel 21. Note that the second spring device 6 is not necessarily required from the viewpoint of preventing contact between the end surface 111 of the soundproof panel 1 and the joining member 22. Also, the shape and structure of the second spring device 6 may be different from those of the spring device 5. [Explanation of symbols]
