Description

[Technical Field]

[0001] The present invention relates to a mounting member, an exterior wall unit, a building, and a mounting method. [Background technology]

[0002] Conventionally, mounting devices for attaching decorative elements to the framework of a building have been known. For example, Patent Document 1 discloses a fastener that attaches multiple wall panels to a pair of C-shaped channels by pressing the wall panels from the outside against the pair of C-shaped channels, which are the framework. This fastener includes a backing plate disposed across both outer surfaces of the pair of C-shaped channels, a head portion disposed outward from the backing plate, a through-hole formed in the backing plate and extending from the head portion to the inside of each inner surface of the pair of C-shaped channels through a gap between the pair of C-shaped channels, a holding pin extending from the through-hole in the backing plate in a direction intersecting the through-hole and clamping the pair of C-shaped channels between the backing plate, and multiple holding pieces connected to the backing plate and attached to the outer surfaces of the multiple wall panels. Each of the holding pieces has a mounting screw that is tightened and moves the holding piece toward the wall panel.

[0003] In Patent Document 1, the fastener is attached to the pair of C-shaped channels by inserting the through-shaft of the fastener into the gap between the pair of C-shaped channels and rotating the through-shaft. In this state, the wall panels are pressed against the pair of C-shaped channels via the multiple pressing pieces and the mounting screws are rotated, thereby attaching the wall panels to the pair of C-shaped channels.

[0004] [Patent Document 1] Publication No. 01-007612 Summary of the Invention [Problem to be solved by the invention]

[0005] In Patent Document 1, a portion of each retaining piece and each mounting screw are exposed to the outside from the joints formed between multiple wall panels so that a worker can operate the mounting screws. In other words, in Patent Document 1, the mounting members and mounting screws are provided in areas that are susceptible to the influence of external factors such as wind, rain, outside temperature, and unnecessary external forces.

[0006] The object of the present invention is to provide a mounting member, exterior wall unit, building, and mounting method that can mount a decorative member to the building's main body in a state where the part for holding the decorative member is less susceptible to the influence of external factors. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems, the present invention provides an attachment member for attaching a decorative member to a body having a first pillar member having a first pillar outer surface and a first pillar inner surface, and a second pillar member having a second pillar outer surface and a second pillar inner surface and adjacent to the first pillar member with a gap provided between the first pillar member and the second pillar member, the attachment member comprising: a first clamping member arranged across the first pillar outer surface and the second pillar outer surface when the decorative member is attached in a normal attachment position; an operated part arranged on the outside of the first clamping member; and an insertion part extending from the operated part through the gap to the inside of at least one of the first pillar inner surface and the second pillar inner surface. and a second clamping member having a clamping piece extending from the insertion portion in a direction intersecting the insertion portion and for clamping at least one pillar member between itself and the first clamping member; and an attachment mechanism connected to the first clamping member and configured to be attachable within the surface of the decorative member, wherein the second clamping member is attached to the first clamping member with the operated portion exposed outside the surface of the decorative member so as to be rotatable between a passing position in which the clamping piece is arranged along the gap to pass through the gap, and a clamping position in which the second clamping member clamps at least one pillar member between itself and the first clamping member.

[0008] According to the present invention, the mounting mechanism can be disposed within the plane of the decorative element, which makes it possible to mount the decorative element to the main body in a state where the mounting mechanism is less susceptible to external factors, compared to when a portion of the mounting mechanism is exposed outside the plane of the decorative element.

[0009] Furthermore, in the present invention, the attachment mechanism can be positioned within the surface of the decorative element, thereby reducing the impact of the attachment mechanism on the aesthetic appearance of the decorative element compared to when part of the attachment mechanism is exposed outside the surface of the decorative element.

[0010] Furthermore, in the present invention, since the operated part is exposed outside the surface of the decorative element, the operated part can be operated from outside the building, which makes it easier to attach the decorative element to the building structure compared to when the operated part is covered within the surface of the decorative element.

[0011] In the mounting member, it is preferable that the first clamping member has a connection portion connected to the mounting mechanism within the plane of the decorative member, a clamping portion for clamping at least one of the pillar members between the clamping piece with the operated portion exposed outside the plane of the decorative member, and a connecting portion connecting the connection portion and the clamping portion.

[0012] According to this configuration, the connecting portion and the clamping portion are separated by the connecting portion, so that when the decorative element is viewed from the outside, the operating portion can be exposed from the decorative element while the attachment mechanism is covered by the decorative element.

[0013] In the mounting member, it is preferable that the second clamping member is mounted to the first clamping member in a state in which its position in a direction perpendicular to the direction in which the insertion portion extends is adjustable.

[0014] According to this configuration, the attachment position of the second clamping member relative to the first clamping member can be adjusted in a direction perpendicular to the direction in which the insertion portion extends, and therefore the attachment position of the decorative member relative to the main body can be adjusted in a direction perpendicular to the direction in which the insertion portion extends.

[0015] In the mounting member, it is preferable that the mounting mechanism has a locking portion that locks onto a locking portion installed on the decorative member, and an attraction mechanism for attracting the locking portion to the connection portion so that the inner surface of the locking portion is in close contact with the outer surface of the connection portion.

[0016] According to this configuration, the decorative member can be attached to the main body by attracting the decorative member to the connecting portion of the first clamping member while the main body is pressed against the inner surface of the clamping portion of the first clamping member by the second clamping member. Therefore, when attaching the decorative member to a member other than the mounting member, such as when pressing the decorative member against the main body as in Patent Document 1, the pressing position of the decorative member will vary depending on the position of the pillar member of the main body and the shape of the outer surface, whereas with the above configuration, the mounting reference surface of the pillar member and the decorative member can be set to a common member (mounting member), thereby improving the accuracy of the mounting position of the decorative member relative to the main body.

[0017] The present invention also provides an exterior wall unit comprising: a decorative member; and an attachment member for attaching the decorative member to a main body having a first pillar member having a first pillar outer surface and a first pillar inner surface, and a second pillar member having a second pillar outer surface and a second pillar inner surface and adjacent to the first pillar member with a gap between them, wherein the attachment mechanism is attached to the decorative member.

[0018] In the present invention, since the attachment member is attached to the decorative element, the decorative element can be easily attached to the main body by operating the operated portion of the second clamping member. In this attached state, the attachment mechanism is covered by the decorative element, thereby achieving the above-mentioned effect.

[0019] The present invention also provides a building comprising a main body having a first pillar member having a first pillar outer surface and a first pillar inner surface, and a second pillar member having a second pillar outer surface and a second pillar inner surface and adjacent to the first pillar member with a gap between it and the first pillar member, a decorative member attached to the main body, an adjacent decorative member attached to the main body so as to be adjacent to the decorative member, and a plurality of mounting members for attaching the decorative member to the main body, wherein the mounting mechanism of the plurality of mounting members is attached within the surface of the decorative member with the operated portion positioned within the range of the gap between the decorative member and the adjacent decorative member.

[0020] In the present invention, all of the operated portions of the multiple attachment members are exposed outside the surface of the decorative member, so that the decorative member can be attached and detached from the outside during maintenance, etc., improving workability.

[0021] In the building, it is preferable that the decorative member has a first outer surface extending along the adjacent direction of the first pillar member and the second pillar member, and a second outer surface extending in a direction perpendicular to the adjacent direction.

[0022] According to this configuration, since the decorative element has a first outer surface and a second outer surface, the decorative element can be suitably attached to the building's main body even if the building has corners.

[0023] The present invention also provides an attachment method for attaching a decorative element using the attachment member to a body having a first pillar member having a first pillar outer surface and a first pillar inner surface, and a second pillar member having a second pillar outer surface and a second pillar inner surface and adjacent to the first pillar member with a gap provided between the first pillar member and the second pillar member, the attachment method comprising: a preparation step of preparing the attachment member and the decorative element; an attachment step of attaching the attachment mechanism to the decorative element; an insertion step of inserting the insertion portion into at least one of the first pillar inner surface and the second pillar inner surface with the second clamping member positioned in the passing posture; and a rotation step of rotating the operated portion so as to switch the second clamping member from the passing posture to the clamping posture.

[0024] According to this aspect, the mounting member can be attached to the decorative member in advance in a factory, etc. Therefore, it is possible to provide an attachment method that is suitable for cases where the decorative member needs to be attached to the main body in a state where the mounting member is attached to the decorative member. [Effects of the Invention]

[0025] According to the present invention, it is possible to provide a mounting member, exterior wall unit, building, and mounting method that can mount a decorative member to the building's main body in a state where the part for holding the decorative member is less susceptible to the influence of external factors.

As shown in Fig. 1 , in the second pillar member 220, the second pillar flange portion 221 on the second direction side has a second pillar inner surface 224, and the second pillar flange portion 221 on the side opposite to the second direction has a second pillar outer surface 225.

[0033] The third pillar member 230 has a pair of third pillar flange portions 231 extending along the second direction and facing each other in the first direction, a third pillar web portion 232 connecting the ends of the pair of third pillar flange portions 231 on the side opposite to the second direction, and a pair of third pillar lip portions 233 extending in a direction approaching each other from the ends of the pair of third pillar flange portions 231 on the second direction side.

[0034] The first pillar member connecting mechanism 240 has a first bolt 241 extending in a first direction so as to penetrate a through hole (not shown) formed in the first pillar web portion 212 and a through hole (not shown) formed in the second pillar web portion 222, a spacer (not shown) attached to the first bolt 241 to form a gap between the first pillar member 210 and the second pillar member 220, and a first nut 242 threaded onto the first bolt 241 and connecting the first pillar member 210 and the second pillar member 220.

[0035] The second pillar member connecting mechanism 250 has a second bolt 251 that extends in the second direction so as to penetrate a through hole (not shown) formed in the first pillar flange portion 211 on the second direction side and a through hole (not shown) formed in the third pillar web portion 232, a spacer (not shown) that is attached to the second bolt 251 to form a gap between the first pillar member 210 and the third pillar member 230, and a second nut 252 that is screwed onto the second bolt 251 and connects the first pillar member 210 and the third pillar member 230.

[0036] The decorative member 10 constitutes an exterior wall unit together with the first attachment members 30. As shown in Fig. 1, the decorative member 10 has a decorative member main body 11, a core material 16 embedded inside the decorative member main body 11 to improve the bending rigidity of the decorative member main body 11, and a first attachment member 20 to which multiple first attachment members 30 are attached.

[0037] The decorative member body 11 is made of concrete and has a portion extending in a first direction, a portion extending in a second direction, and a portion connecting the two. The decorative member body 11 has a first placement portion 15 in which a first attachment member 20 (described later) is placed (embedded). As shown in FIG. 1 , the decorative member body 11 has a first outer surface 13 extending in the first direction (corresponding to the "adjacent direction") and located flush with a first adjacent outer surface 93 of a first adjacent decorative member body 90 (described later), and a second outer surface 14 extending in the second direction and located flush with a second adjacent outer surface 153 of a second adjacent decorative member body 150 (described later). In this embodiment, as shown in FIG. 1 , the dimension of the first outer surface 13 in the first direction is smaller than the dimension of the first adjacent outer surface 93 in the first direction, and the dimension of the second outer surface 14 in the second direction is smaller than the dimension of the second adjacent outer surface 153 in the second direction.

[0038] The core material 16 is embedded in the decorative element main body 11 and has a first portion 17 extending in a first direction and a second portion 18 extending in a second direction. The first portion 17 has an inner surface 19 (hereinafter referred to as the core inner surface 19) extending in the first direction. In this embodiment, a first attachment member 20 is fixed to a portion of the core inner surface 19.

[0039] The first attached member 20 has a pair of first flange portions 21 extending along the second direction and facing each other in the first direction, a first web portion 22 connecting the ends of the pair of first flange portions 21 opposite the second direction and fixed to the first part 17 of the core material 16, and a pair of first lip portions 23 (corresponding to "engaged portions") extending toward each other from the ends of the pair of first flange portions 21 on the second direction side. The decorative member main body 11 has a first recess 5 formed so as to be recessed from the inner surface 12 extending in the first direction of the decorative member main body 11 toward the direction opposite to the second direction. In this embodiment, the area surrounded by the pair of first flange portions 21 and the first web portion 22 is the first recess 5.

[0040] 1 and 2, the multiple first mounting members 30 are arranged in a vertical row. In this embodiment, since each of the multiple first mounting members 30 has substantially the same configuration, the following description will only describe the configuration of a single first mounting member 30. Specifically, the first mounting member 30 includes a first clamping member 40 that is arranged across the first column outer surface 215 and the second column outer surface 225 when the decorative member 10 is attached in the correct attachment position, a second clamping member 50 that is connected to the first clamping member 40 and clamps at least one of the column members between itself and the first clamping member 40, and an attachment mechanism 60 that is connected to the first clamping member 40 and configured to be attachable within the plane of the decorative member 10 (within the range of the decorative member 10 when viewed from the outside).

[0041] As shown in Figure 2, the first clamping member 40 has a connection portion 41 connected to the attachment mechanism 60 within the plane of the decorative member 10, a clamping portion 43 for clamping at least one pillar member between the clamping piece 55 described later of the second clamping member 50 while exposing the operated portion 51 described later of the second clamping member 50 outside the plane of the decorative member 10 (outside the range of the decorative member when viewing the decorative member 10 from the outside), and a connecting portion 46 connecting the connection portion 41 and the clamping portion 43.

[0042] 1, the connecting portion 41 extends in a first direction so as to face each of the pair of first lip portions 23 of the first attached member 20. The connecting portion 41 cooperates with the attachment mechanism 60 to hold the decorative element 10.

[0043] As shown in Figures 1 to 7, the clamping portion 43 has a plate-shaped portion 44 extending across the first column outer surface 215 and the second column outer surface 225 so that the operated portion 51, described later, can be attached to the decorative element 10 while being exposed from the decorative element 10 when viewed from the outside, and a pair of protrusions 45 extending outward (toward the outside of the building 300) from the plate-shaped portion 44 to prevent the second clamping member 50 from rotating at a predetermined rotational position.

[0044] The connecting portion 46 connects the connecting portion 41 and the clamping portion 43 while they are spaced apart from each other. As shown in Fig. 1, the connecting portion 46 according to this embodiment extends obliquely in a plan view in order to shift the connection position of the connecting portion 41 relative to the mounting mechanism 60 toward the outside of the building 300.

[0045] 1 and 2, the second clamping member 50 has an operated portion 51 arranged outside the first clamping member 40, an insertion portion 54 extending from the operated portion 51 to the inside of at least one of the first pillar inner surface 214 and the second pillar inner surface 224 through the gap between the first pillar member 210 and the second pillar member 220, and a clamping piece 55 for clamping at least one of the pillar members between itself and the first clamping member 40. The second clamping member 50 is attached to the first clamping member 40 with the operated portion 51 exposed outside the surface of the decorative member 10 so as to be rotatable between a passing position (see FIG. 15) in which the clamping piece 55 is arranged along the gap between the first pillar member 210 and the second pillar member 220 to pass through the gap, and a clamping position (see FIG. 16) in which at least one of the pillar members is clamped between itself and the first clamping member 40.

[0046] 2, the operated portion 51 has a head portion 52 that is operated to rotate the entire second clamping member 50, and a rotation restricting portion 53 that is provided integrally with the head portion 52 and allows rotation of the second clamping member 50 in the clamping direction from the passing position toward the clamping position, and restricts rotation of the second clamping member 50 in the clamping direction beyond the clamping position. Specifically, in this embodiment, as shown in FIG. 4, the dimensions of the rotation restricting portion 53 are designed so that when the second clamping member 50 rotates at an angle between the passing position and the clamping position, the rotation restricting portion 53 does not come into contact with the pair of protrusions 45, but comes into contact with the pair of protrusions 45 when the second clamping member 50 is rotated in the clamping direction and reaches the clamping position.

[0047] The insertion portion 54 passes through a clamping through-hole HL2 (see FIG. 4) formed in the clamping portion 43 and extends to the inside of at least one of the first pillar inner side surface 214 and the second pillar inner side surface 224. In this embodiment, the clamping through-hole HL2 extends in a direction perpendicular to the extension direction of the insertion portion 54 so that the attachment position of the second clamping member 50 relative to the first clamping member 40 (clamping portion 43) can be adjusted.

[0048] As shown in FIG. 12 , the clamping pieces 55 extend from the insertion portion 54 in a direction intersecting the insertion portion 54. When the second clamping member 50 is rotated to the clamping position, the clamping pieces 55 press the first-column inner surface 214 of the first pillar member 210 outward (toward the outside of the building 300), thereby clamping the first pillar member 210 between the first clamping member 40 (clamping portion 43). When the second clamping member 50 is rotated to the passing position, the clamping pieces 55 are released from pressing the first-column inner surface 214. Note that the clamping pieces 55 may extend in a bifurcated shape from the insertion portion 54 along a direction intersecting the insertion portion 54. In this case, the clamping pieces 55 rotated to the clamping position of the second clamping member 50 press the first-column inner surface 214 and the second-column inner surface 224 outward.

[0049] 1, the attachment mechanism 60 is attached to the surface of the decorative member 10 with the operated portion 51 disposed within the gap between the decorative member 10 and the first adjacent decorative member 80. Specifically, the attachment mechanism 60 has a locking portion 64 that locks onto a pair of first lip portions 23 (locked portions) installed on the decorative member 10 so as to cover part of the first recess 5 when the decorative member 10 is viewed from the inside, and a first attracting mechanism 70 (corresponding to an "attracting mechanism") that attracts the locking portion 64 to the connecting portion 41 so that the inner surfaces 62 (hereinafter referred to as the locked inner surfaces 62) of the pair of first lip portions 23 come into close contact with the outer surface 42 (hereinafter referred to as the connecting outer surface 42) of the connecting portion 41.

[0050] The locking portion 64 is a plate-shaped member that locks onto the pair of first lip portions 23 by coming into contact with outer surfaces 63 (hereinafter referred to as locked outer surfaces 63) of the pair of first lip portions 23 through the first recess 5. The locking portion 64 has a shape that allows it to be inserted into a gap in the first direction that is formed between the pair of first lip portions 23 in a predetermined position (hereinafter referred to as the insertion position), and that allows it to come into contact with the locked outer surfaces 63 in a position rotated a predetermined angle from the insertion position (hereinafter referred to as the contact position). Specifically, as shown in Figure 4, the locking portion 64 has a pair of side end faces 65 spaced apart by a second dimension L2 (see Figure 4) that is smaller than the first dimension L1 (see Figure 1) of the gap in the first direction between the pair of first lip portions 23, a pair of cutout end faces 66 spaced apart by a fourth dimension L4 (see Figure 4) that is larger than the first dimension L1 and is set to be equal to or smaller than the third dimension L3 (see Figure 1) in the first direction between the pair of first flange portions 21, and a pair of cutout portions 67 formed between the side end faces 65 and the cutout end faces 66 to allow the locking portion 64 to rotate to one side between the pair of first flange portions 21.

[0051] 2, the first attraction mechanism 70 includes a first attraction bolt 71 extending to penetrate the locking portion 64 and the connection portion 41, and a first attraction nut 72 threadedly engaged with the first attraction bolt 71 inside the connection portion 41. Specifically, the first attraction bolt 71 includes a first attraction bolt body 71A that penetrates a connection through-hole HL1 (see FIGS. 5 and 7) formed in the connection portion 41 and a locking through-hole HL3 formed in the locking portion 64 so as to overlap with the connection through-hole HL1 when the decorative element 10 is viewed from the outside, and a first attraction bolt head 71B that is sized so as not to be able to be inserted through the connection through-hole HL1 and the locking through-hole HL3 and is provided outside the locking portion 64. The first attraction nut 72 is threadedly engaged with the first attraction bolt 71 so as to clamp the first clamping member 40 between the locking portion 64 and the first attraction bolt 71. By threading the first attachment nut 72 onto the first attachment bolt 71, the locking portion 64 is attracted to the connection portion 41 and the first attachment member 30 is attached to the decorative member 10.

[0052] As shown in FIG. 1, the first adjacent decorative member 80 has a first adjacent decorative member main body 90 and a second attachment member 94 to which a plurality of second attachment members 100 are attached.

[0053] The first adjacent decorative member body 90 has a portion extending in a first direction and is made of concrete. The first adjacent decorative member body 90 has a second placement portion 91 in which a second attachment member 94 is placed (embedded).

[0054] The second attached member 94 has a pair of second flange portions 95 extending along the second direction, a second web portion 96 connecting the ends of the pair of second flange portions 95 on the side opposite to the second direction, and a pair of second lip portions 97 extending toward each other from the ends of the pair of second flange portions 95 on the second direction side. The first adjacent decorative member main body 90 has a second recess 85 formed so as to be recessed in the direction opposite to the second direction from an inner surface 92 (hereinafter referred to as the first adjacent inner surface 92) of the first adjacent decorative member main body 90 extending in the first direction. In this embodiment, the area surrounded by the pair of second flange portions 95 and the second web portion 96 is the second recess 85.

[0055] 1, multiple second attachment members 100 are arranged in a vertical row. In this embodiment, each of the multiple second attachment members 100 has substantially the same configuration, and therefore, the following description will focus on the configuration of only a single second attachment member 100.

Note that a mechanism for preventing the second fixing bolt 134 from loosening is provided between the second locking plate 132 and the second column lip portion 223, but a description thereof will be omitted here.

[0059] As shown in FIG. 1, the second adjacent decorative member 140 has a second adjacent decorative member body 150 and a third mounting member 154 to which a plurality of third mounting members 160 are attached.

[0060] The second adjacent decorative member body 150 has a portion extending in the second direction and is made of concrete. The second adjacent decorative member body 150 has a third placement portion 151 in which a third attachment member 154 is placed (embedded).

[0061] The third attached member 154 has a pair of third flange portions 155 extending along the first direction, a third web portion 156 connecting the ends of the pair of third flange portions 155 on the side opposite to the first direction, and a pair of third lip portions 157 extending toward each other from the ends of the pair of third flange portions 155 on the first direction side. The second adjacent decorative member main body 150 has a third recess 145 formed so as to be recessed in the direction opposite to the first direction from an inner surface 152 (hereinafter referred to as the second adjacent inner surface 152) of the second adjacent decorative member main body 150 extending in the second direction. In this embodiment, the area surrounded by the pair of third flange portions 155 and the third web portion 156 is the third recess 145.

[0062] 1, multiple third mounting members 160 are arranged in a vertical row. In this embodiment, each of the multiple third mounting members 160 has substantially the same configuration, and therefore, the following description will focus on the configuration of only a single third mounting member 160. Specifically, the third mounting member 160 has a third mounting member main body 170, a second adjacent-side mounting mechanism 180 for mounting the second adjacent decorative member 140 to the third mounting member main body 170, and a third-pole-side mounting mechanism 190 for mounting the third pole member 230 to the third mounting member main body 170.

Specifically, the second adjacent-side portion 171 is attached to the second adjacent inner surface 152 of the second adjacent decorative member body 150 via a second adjacent-side attachment mechanism 180, and the third-post-side portion 172 is attached to a pair of third-post lips 233 of the third post member 230 via a third-post-side attachment mechanism 190.

[0064] 1 , the second adjacent-side attachment mechanism 180 includes a second adjacent-side clamping plate 181 that engages with the pair of third flange portions 155 so as to clamp the pair of third lip portions 157 between the second adjacent-side clamping plate 181 and the second adjacent-side portion 171, and a third attracting mechanism 182 that attracts the second adjacent-side clamping plate 181 to the second adjacent-side portion 171 so that the inner surfaces 158 of the pair of third lip portions 157 are in close contact with the outer surface 173 of the second adjacent-side portion 171. The third attracting mechanism 182 has a configuration similar to that of the first attracting mechanism 70. Specifically, the third attracting mechanism 182 includes a third attracting bolt 183 that extends in the first direction to penetrate the second adjacent-side clamping plate 181 and the second adjacent-side portion 171, and a third attracting nut 184 that threads onto the third attracting bolt 183. The third pull bolt 183 has a third pull bolt body that passes through a through-hole (not shown) formed in each of the second adjacent-side clamping plate 181 and the second adjacent-side portion 171 while overlapping when viewed from the first direction, and a third pull bolt head that is sized so as not to be able to pass through a through-hole (not shown) formed in each of the second adjacent-side clamping plate 181 and the second adjacent-side portion 171. By screwing a third pull nut 184 onto the third pull bolt 183, the second adjacent-side clamping plate 181 is attracted to the second adjacent-side portion 171 and the second adjacent-side portion 171 is attached to the second adjacent inner surface 152 of the second adjacent decorative member main body 150.

[0065] 1 , the third-column-side mounting mechanism 190 includes a third-column-side clamping plate 191 having a portion extending in the first direction so as to face the pair of third-column lip portions 233, a third locking plate 192 that engages with the pair of third-column flange portions 231 to clamp the third-column-side portion 172 between the third-column-side clamping plate 191 via the pair of third lip portions 157, and a third fixing mechanism 193 that fixes the third-column-side portion 172 to the third-column lip portion 233 via the third-column-side clamping plate 191 and the third locking plate 192. The third fixing mechanism 193 has a configuration similar to that of the first attracting mechanism 70. Specifically, the third fixing mechanism 193 includes a third fixing bolt 194 that extends in the second direction so as to penetrate the third locking plate 192, the third-column-side portion 172, and the third-column-side clamping plate 191, and a third fixing nut 195 that threads onto the third fixing bolt 194. The third fixing bolt 194 has a third fixing bolt body that passes through a through-hole (not shown) formed in each of the third locking plate 192, the third column-side portion 172, and the third column-side clamping plate 191 while overlapping when viewed from the second direction, and a third fixing bolt head that is sized so as not to be able to pass through a through-hole (not shown) formed in each of the third locking plate 192, the third column-side portion 172, and the third column-side clamping plate 191. A third fixing nut 195 is threadedly engaged with the third fixing bolt 194, thereby fixing the third column-side portion 172 to the pair of third column lip portions 233 of the third column member 230. Note that a mechanism for preventing the third fixing bolt 194 from loosening is provided between the third locking plate 192 and the third column lip portion 233, but a description thereof will be omitted here.

[0066] Next, a method for attaching the decorative member 10 to the body 200 using the first attachment member 30 will be described with reference to FIGS.

[0067] First, a preparation step is performed to prepare the first attachment member 30 and the decorative member 10, as described with reference to Figures 1 to 13. In this embodiment, a first adjacent decorative member 80, a second attachment member 100, a second adjacent decorative member 140, and a third attachment member 160 are prepared in this preparation step.

[0068] Next, as shown in FIG. 14 , an attachment process is performed to attach the attachment mechanism 60 to the decorative member 10. In this attachment process, first, with the locking portion 64 positioned in the insertion position, the locking portion 64 is moved into the first attachment member 20 so that the connecting outer surface 42 is in close contact with the locked inner surface 62. Next, the locking portion 64 is rotated between the pair of first flange portions 21 so that the locking portion 64 is in the contact position, and the locking portion 64 is brought into contact with the locked outer surface 63. Then, the first attachment nut 72 is tightened so that the locking portion 64 is attracted to the connection portion 41. This completes the exterior wall unit including the decorative member 10 and the first attachment member 30. Note that the attachment process is performed with the operated portion 51 of the second clamping member 50 exposed when the decorative member 10 is viewed from the outside.

[0069] Next, a first adjacent decorative member mounting step is performed in which the first adjacent decorative member 80 is mounted to the second pillar member 220 from the inside of the body 200 using the second mounting member 100.

[0070] Next, a second adjacent decorative member mounting step is performed in which the second adjacent decorative member 140 is mounted to the third pillar member 230 from the inside of the body 200 using the third mounting member 160. The second adjacent decorative member mounting step may be performed prior to the first adjacent decorative member mounting step.

[0071] 15 , with the second clamping member 50 positioned in the passing posture, an insertion step is performed in which the insertion portion 54 is inserted into the inside of at least one of the first pillar inner surface 214 and the second pillar inner surface 224. In this insertion step, with the operated portion 51 operated so that the second clamping member 50 is in the passing posture, the insertion portion 54 is inserted into the gap between the first pillar member 210 and the second pillar member 220. In the insertion step, by inserting the insertion portion 54 into the gap between the first pillar member 210 and the second pillar member 220, when an external force acts on the decorative member 10, movement of the decorative member 10 in the first direction and the opposite direction to the first direction is restricted so that the decorative member 10 moves away from the main body 200.

[0072] 16, a rotation process is performed in which the operated portion 51 is rotated so that the second clamping member 50 is switched from the passing position to the clamping position. In the rotation process, the clamping piece 55 presses the first pillar inner surface 214 of the first pillar member 210, thereby restricting movement of the decorative member 10 in the second direction and the opposite direction so as to move away from the building 200 when an external force acts on the decorative member 10. Furthermore, as described above, in this embodiment, the operated portion 51 is exposed from the gap between the first outer surface 13 and the first adjacent outer surface 93 when viewed from the outside. Therefore, even if the first adjacent decorative member 80 and the second adjacent decorative member 140 are attached to the building 200 in advance, the second clamping member 50 can be switched to the clamping position by operating the operated portion 51 from outside the building 300. That is, in this embodiment, even if it is difficult to attach the decorative member 10 from the inside of the body 200, the work of attaching the decorative member 10 can be completed from the outside of the body 200.

[0073] Next, the features and effects of the building 300 and the installation method according to this embodiment described above will be listed.

[0074] According to the first attachment member 30 of this embodiment, the attachment mechanism 60 can be disposed within the plane of the decorative member 10. Therefore, compared to when a portion of the attachment mechanism 60 is exposed outside the plane of the decorative member 10, the decorative member 10 can be attached to the main body 200 in a state where the attachment mechanism 60 is less susceptible to external factors.

[0075] Furthermore, according to the first attachment member 30 of this embodiment, the attachment mechanism 60 can be positioned within the surface of the cosmetic member 10, thereby reducing the impact of the attachment mechanism 60 on the aesthetic appearance of the cosmetic member 10 compared to when a portion of the attachment mechanism 60 is exposed outside the surface of the cosmetic member 10.

[0076] Furthermore, according to the first attachment member 30 of this embodiment, the operated portion 51 is exposed outside the surface of the decorative member 10, so the operated portion 51 can be operated from outside the building 300. Therefore, compared to when the operated portion 51 is covered within the surface of the decorative member 10, the decorative member 10 can be attached to the building 200 more easily.

[0077] Furthermore, according to the first attachment member 30 of this embodiment, the connecting portion 41 and the clamping portion 43 are separated by the connecting portion 46. Therefore, when the decorative member 10 is viewed from the outside, the attached mechanism 60 is covered by the decorative member 10, and the operated portion 51 can be exposed from the decorative member 10.

[0078] Furthermore, according to the first attachment member 30 of this embodiment, the attachment position of the second clamping member 50 relative to the first clamping member 40 can be adjusted in a direction perpendicular to the extension direction of the insertion portion 54. Therefore, the attachment position of the decorative member 10 relative to the main body 200 can be adjusted in a direction perpendicular to the extension direction of the insertion portion 54.

[0079] Furthermore, with the first attachment member 30 according to this embodiment, the decorative member 10 can be attached to the frame 200 by attracting the decorative member 10 to the connecting portion 41 of the first attachment member 40 while the frame 200 is pressed against the inner surface of the clamping portion 43 of the first attachment member 40 by the second clamping member 50. Therefore, when attaching the decorative member 10 to a member other than the first attachment member 30, such as when pressing the decorative member 10 against the frame 200, the pressing position of the decorative member 10 will vary depending on the position of the pillar member of the frame 200 and the shape of the outer surface. However, in this embodiment, the attachment reference plane for the frame 200 and the decorative member 10 can be set to a common member (the first attachment member 30), thereby improving the accuracy of the attachment position of the decorative member 10 relative to the frame 200.

[0080] Furthermore, according to the exterior wall unit of this embodiment, the first attachment member 30 is attached to the decorative member 10, so that the decorative member 10 can be easily attached to the main body 200 by operating the operated portion 51 of the second clamping member 50. In this attached state, the attachment mechanism 60 is covered by the decorative member 10, so that the effect of the first attachment member 30 can be obtained.

[0081] Furthermore, according to the building 300 of this embodiment, all of the operated parts 51 of the multiple first attachment members 30 are exposed outside the surface of the decorative member 10, so that the decorative member 10 can be attached and detached from the outside during maintenance, etc., thereby improving workability.

[0082] Furthermore, according to the building 300 of this embodiment, the decorative element 10 has a first outer surface 13 and a second outer surface 14, so that even if the building 300 has corner portions, the decorative element 10 can be suitably attached to the main body 200 of the building 300.

[0083] Furthermore, according to the attachment method of this embodiment, the first attachment member 30 can be attached to the decorative member 10 in advance, for example, in a factory. Therefore, it is possible to provide an attachment method that is suitable for cases where the decorative member 10 needs to be attached to the main body 200 with the first attachment member 30 attached to the decorative member 10.

[0084] (Other embodiments) Finally, other embodiments of the present invention will be described.

[0085] In the above embodiment, an example has been described in which the position of the second clamping member 50 in the direction perpendicular to the direction in which the insertion portion extends is adjustable by extending the clamping through-hole HL2 of the clamping portion 43 in the direction perpendicular to the direction in which the insertion portion 54 extends. However, instead of the clamping through-hole HL2, the connection through-hole HL1 of the connection portion 41 may be extended in the direction perpendicular to the direction in which the insertion portion 54 extends, thereby making it possible to adjust the position of the second clamping member 50 in the direction perpendicular to the direction in which the insertion portion extends.

[0086] In the above embodiment, the second clamping member 50 only needs to be attached to the first clamping member 40 with at least the operated portion 51 exposed, and the second clamping member 50 may also be attached to the first clamping member 40 with each portion of the second clamping member 50 other than the operated portion 51 arranged within the plane of the decorative member 10.
