Description

[Technical Field]

[0001] The present disclosure relates to an attachment member, a building, and a method for constructing a building. [Background technology]

[0002] In the advertisement fixing structure described in Patent Document 1, the advertisement is attached to the wall surface of a building via an advertisement fixing device, which is fixed directly to the wall surface with a bolt. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3199402 Summary of the Invention [Problem to be solved by the invention]

[0004] When an advertisement fixture is fixed directly to a wall surface with bolts, the weight of the advertisement is applied to the wall surface via the advertisement fixture and the bolts, which may result in insufficient mounting strength for the advertisement. [Means for solving the problem]

[0005] (1) The accessory mounting member that solves the above problem is an accessory mounting member for mounting an accessory on the outdoor side of an exterior wall having a structural material and an exterior wall material provided outdoors of the structural material, and is provided with a fixing portion that is fixed to the structural material, a mounting portion to which the accessory is attached, and a connecting portion that connects the fixing portion and the mounting portion, and the connecting portion is provided with a flange that protrudes in a direction that intersects with the direction in which the connecting portion extends.

[0006] According to this configuration, the accessory mounting member is fixed to the structural material, and therefore the mounting strength of the accessory can be improved compared to when it is fixed to the exterior wall material. Furthermore, because the connecting portion is provided with a flange, when sealing the attachment member and the exterior wall material, a sealant can be provided between the flange and the exterior wall material, which improves the waterproofing between the attachment member and the exterior wall material compared to when a triangular seal is used between the attachment member and the exterior wall material.

[0007] (2) In the accessory mounting member of (1) above, the flange is provided around the entire periphery of the connecting portion when viewed in the direction in which the connecting portion extends. With this configuration, a sealant can be provided between the flange and the exterior wall material around the entire periphery of the connection part when viewed from the direction in which the connection part extends, thereby further improving the waterproofing between the accessory mounting member and the exterior wall material.

[0008] (3) A building that solves the above problem is a building that comprises an exterior wall having a structural material and an exterior wall material located outdoors of the structural material, and an accessory mounting member for mounting accessories on the outdoors side of the exterior wall, wherein the accessory mounting member has a fixing part that is fixed to the structural material, a mounting part that is located outdoors of the exterior wall material and to which the accessory is mounted, and a connecting part that connects the fixing part and the mounting part, and a flange that protrudes in a direction that intersects with the extending direction of the connecting part is provided at the part of the connecting part that is located outdoors of the exterior wall material, and a sealing material is provided between the flange and the exterior wall material.

[0009] According to this configuration, the accessory mounting member is fixed to the structural material, and therefore the mounting strength of the accessory can be improved compared to when it is fixed to the exterior wall material. In addition, a flange is provided at the connection portion, and a sealing material is provided between the flange and the exterior wall material, thereby improving the waterproofing between the accessory mounting member and the exterior wall material compared to when a triangular seal is used between the accessory mounting member and the exterior wall material.

[0010] (4) In the building of (3) above, the exterior wall has a plurality of the exterior wall materials, the plurality of the exterior wall materials are arranged at intervals, and the connection portion is inserted into the joints of the exterior wall materials. With this configuration, there is no need to provide a through hole in the exterior wall material for inserting the connecting portion.

[0011] (5) In the building of (4) above, the structural material has a cross member, which has a web, a lower flange located below the web, an upper flange located above the web, and a stiffener connecting the web, the lower flange, and the upper flange, the joints have vertical joints provided between adjacent exterior wall materials in the direction in which the cross member extends, the stiffener and the vertical joints are provided at the same position in the direction in which the cross member extends, the connecting portion has a base inserted into the vertical joint and a shift portion connecting the base and the fixing portion so that the position of the fixing portion relative to the base is shifted in the direction in which the cross member extends, and the fixing portion is fixed to the stiffener in a state in which it is arranged so as to follow one end face of the stiffener in the direction in which the cross member extends.

[0012] When the stiffener and the vertical joint of the exterior wall material are positioned at the same position in the direction in which the horizontal member extends and the connecting portion is inserted into the vertical joint, if the connecting portion and the fixing portion are positioned at the same position in the direction in which the horizontal member extends, the fixing portion will interfere with the stiffener. In contrast, with the above configuration, the shift portion shifts the position of the fixing portion relative to the base portion in the direction in which the horizontal member extends, preventing the fixing portion from interfering with the stiffener. The fixing portion is fixed to the stiffener while being positioned along one end face of the stiffener in the direction in which the horizontal member extends. Therefore, the fixing portion can be stably fixed to the stiffener.

[0013] (6) In the building of (3) or (4) above, the structural material has a column, the column is composed of two C-shaped steel beams, and the fixing part is fixed to the column while being positioned between the two C-shaped steel beams. With this configuration, the accessory mounting member can be firmly fixed to the pillar.

[0014] (7) In the building of any one of (3) to (6) above, the connection portion has an inclined portion that is inclined downward from the fixed portion toward the mounting portion.

[0015] With this configuration, even if moisture does get in between the attachment member and the exterior wall material, the inclined portion guides the moisture to the outside, making it less likely for moisture to get inside the building.

[0016] (8) In the building of any one of (3) to (7) above, a bond breaker is provided in a portion of the connecting portion that is located indoors relative to the flange and outdoors relative to the exterior wall material.

[0017] With this configuration, the bond breaker prevents the sealant between the flange and the exterior wall material from coming into contact with the joint, thereby forming a two-sided bond between the flange and the exterior wall material, thereby extending the life of the sealant.

[0018] (9) In the building of (8) above, the bond breaker is further provided in a portion of the connection portion that faces the exterior wall material. According to this configuration, the bond breaker is provided at the portion of the connection portion facing the exterior wall material, thereby preventing the sealant that has flowed between the connection portion and the exterior wall material from coming into contact with the connection portion.

[0019] (10) A method of constructing a building described in (8) or (9) above, comprising a bond breaker installation step of providing the bond breaker at the connection portion, and an accessory installation step of attaching the accessory installation member to the exterior wall, wherein the bond breaker installation step is carried out before the accessory installation step.

[0020] According to this method, the outer wall does not get in the way when the bond breaker is provided at the connection portion, which makes the bond breaker attachment process easier. [Effects of the Invention]

[0021] According to the accessory mounting member, building, and building construction method disclosed herein, the mounting strength of the accessory can be improved. [Brief explanation of the drawings]

The beam 22 has a stiffener 27 connecting the web 24, the lower flange 25, and the upper flange 26.

[0027] 3, a second fixing hole 27a is provided in the stiffener 27. The second fixing hole 27a penetrates the stiffener 27 in the first direction X. As shown in Figure 1, the multiple exterior wall materials 13 are provided on the outdoor side of the structural materials 12. Of the multiple exterior wall materials 13, the exterior wall material 13 provided on the outdoor side of the first column 21a and the beam 22 is referred to as the first exterior wall material 13a. Of the multiple exterior wall materials 13, the exterior wall material 13 provided on the outdoor side of the second column 21b is referred to as the second exterior wall material 13b. The second exterior wall material 13b is located above the first exterior wall material 13a.

[0028] As shown in FIG. 4, the multiple exterior wall materials 13 are arranged at intervals in the first direction X and the vertical direction Z. The multiple first exterior wall materials 13a are arranged at intervals in the first direction X. The multiple second exterior wall materials 13b are arranged at intervals in the first direction X. The second exterior wall materials 13b are arranged at intervals from the first exterior wall materials 13a in the vertical direction Z. The joints G of the exterior wall materials 13 include vertical joints G1 provided between adjacent exterior wall materials 13 in the first direction X and horizontal joints G2 provided between adjacent exterior wall materials 13 in the vertical direction Z. The vertical joints G1 are provided at the same positions as the stiffeners 27 of the beams 22 in the first direction X (see FIG. 3).

[0029] As shown in Figures 1 to 3, each exterior wall material 13 of this embodiment has a frame 31 and an exterior wall panel 32 fixed to the outdoor surface of the frame 31. Each exterior wall material 13 of this embodiment is attached to the structural material 12 by a locking method.

[0030] <Attachment parts for accessories> As shown in Figures 2 and 3, the building 10 is provided with an accessory mounting member 15 for mounting an accessory 100 on the outdoor side of the exterior wall 11. The accessory 100 of this embodiment has an accessory main body (not shown) and a bracket 101. The accessory main body is, for example, a signboard. The accessory mounting member 15 is made of metal.

[0031] The building 10 of this embodiment is equipped with a first accessory mounting member 15a and a second accessory mounting member 15b as accessory mounting members 15. The first accessory mounting member 15a is an accessory mounting member 15 fixed to a column 21. The second accessory mounting member 15b is an accessory mounting member 15 fixed to a beam 22.

[0032] As shown in Figures 5 and 6, the first accessory mounting member 15a and the second accessory mounting member 15b each have a fixing portion 51, a mounting portion 52, and a connecting portion 53. The fixing portion 51 is located closer to the interior of the building than the exterior wall material 13 in the second direction Y. The fixing portion 51 is a portion that is fixed to the structural material 12. The mounting portion 52 is located closer to the exterior of the building than the exterior wall material 13 in the second direction Y. The mounting portion 52 is a portion to which the accessory 100 is attached. The connecting portion 53 connects the fixing portion 51 and the mounting portion 52. As will be described in detail later, the shape of the connecting portion 53 differs between the first accessory mounting member 15a and the second accessory mounting member 15b.

[0033] In this embodiment, the fixing portion 51, the mounting portion 52, and the connecting portion 53 of the first accessory mounting member 15a are formed by a single flat plate. The fixing portion 51, the mounting portion 52, and the connecting portion 53 of the second accessory mounting member 15b are formed by welding three plates together. The flat first plate forms the fixing portion 51 of the second accessory mounting member 15b. The flat second plate forms a base portion 531 (described later) of the mounting portion 52 and the connecting portion 53 of the second accessory mounting member 15b. The third plate forms a shift portion 532 (described later) of the connecting portion 53 of the second accessory mounting member 15b.

[0034] 2 and 3, a fixing hole 51a is provided in the fixing portion 51. The fixing hole 51a penetrates the fixing portion 51 in the plate thickness direction. As shown in Fig. 2, the fixing portion 51 of the first incidental object mounting member 15a is fixed to the pillar 21. In this embodiment, the fixing portion 51 of the first incidental object mounting member 15a is disposed between two C-shaped steels 23. The fixing portion 51 of the first incidental object mounting member 15a is fixed to the pillar 21 by a bolt B inserted through the fixing hole 51a of the fixing portion 51 and the first fixing holes 23a of the two C-shaped steels 23, and a nut N engaged with the bolt B.

[0035] 3, the fixing portion 51 of the second incidental object mounting member 15b is fixed to the beam 22. In this embodiment, the fixing portion 51 of the second incidental object mounting member 15b is disposed so as to follow one end surface 27b of the stiffener 27 in the first direction X. The fixing portion 51 of the second incidental object mounting member 15b is fixed to the stiffener 27 by a bolt B inserted through the fixing hole 51a of the fixing portion 51 and the second fixing hole 27a of the stiffener 27, and a nut N engaged with the bolt B.

[0036] 5 and 6, the mounting portion 52 is provided with a mounting hole 52a for mounting the bracket 101 of the accessory 100. The mounting hole 52a penetrates the mounting portion 52 in the plate thickness direction. The mounting hole 52a is an elongated hole extending in the second direction Y.

[0037] 2, the connection portion 53 of the first accessory mounting member 15a extends linearly in the second direction Y in a plan view. The connection portion 53 of the first accessory mounting member 15a is inserted into the vertical joint G1 of the exterior wall material 13.

[0038] 3, the connecting portion 53 of the second accessory mounting member 15b has, in a plan view, a base portion 531 extending in the second direction Y and a shift portion 532 extending in the first direction X. The base portion 531 is inserted into the vertical joint G1 of the exterior wall material 13. The base portion 531 is aligned with the stiffener 27 of the beam 22 in the second direction Y. The shift portion 532 connects the base portion 531 and the fixing portion 51 such that the position of the fixing portion 51 is shifted relative to the base portion 531 in the first direction X.

[0039] 5 and 6, the connecting portion 53 of the first accessory mounting member 15a and the connecting portion 53 of the second accessory mounting member 15b each have an inclined portion 53a and a horizontal portion 53b. The inclined portion 53a is located closer to the fixed portion 51 than the horizontal portion 53b in the direction in which the connecting portion 53 extends. The inclined portion 53a is inclined relative to the horizontal direction so as to be positioned downward as it moves from the fixed portion 51 toward the mounting portion 52. The horizontal portion 53b extends in the horizontal direction.

[0040] The first accessory mounting member 15a and the second accessory mounting member 15b each have a flange 54. The flange 54 is provided at a portion of the connecting portion 53 that is located outside of the exterior building material 13. The flange 54 protrudes in a direction that intersects with the direction in which the connecting portion 53 extends. The flange 54 has an opposing surface 54a that faces the outer surface 130 of the exterior building material 13.

[0041] 4, the flange 54 of this embodiment is provided around the entire periphery of the connecting portion 53 when viewed in the extending direction of the connecting portion 53. The width of the flange 54 in the first direction X is greater than the width of the vertical joint G1 in the first direction X.

[0042] As shown in Figures 5 and 6, the first accessory mounting member 15a and the second accessory mounting member 15b each have a bond breaker 55. The bond breaker 55 is made of a material to which the sealant 16, which will be described later, does not easily adhere. The bond breaker 55 of this embodiment is made of polyethylene. One side of the bond breaker 55 is an adhesive surface. The bond breaker 55 is affixed to the outer circumferential surface of the connection portion 53. The bond breaker 55 is provided in a portion that is located indoors relative to the opposing surface 54a of the flange 54 and outdoors relative to the outer surface 130 of the exterior building material 13 in the extension direction of the connection portion 53. The bond breaker 55 of this embodiment is further provided in a portion of the connection portion 53 that faces the exterior building material 13, more specifically, in a portion of the connection portion 53 that faces the side surface of the exterior wall panel 32.

[0043] <Sealing material> As shown in Fig. 4, a sealant 16 is provided in the joints G of the exterior wall material 13. The sealant 16 is provided in each of the vertical joints G1 and the horizontal joints G2.

[0044] 7 and 8, the sealant 16 is provided between the accessory mounting member 15 and the exterior wall material 13. The sealant 16 is provided between the opposing surface 54a of the flange 54 of the accessory mounting member 15 and the outer surface 130 of the exterior wall material 13.

[0045] As described above, a bond breaker 55 is provided at the connection 53 of the accessory mounting member 15, at a portion located indoors relative to the flange 54 and outdoors relative to the exterior wall material 13. This prevents the sealant 16 provided between the flange 54 and the exterior wall material 13 from coming into contact with the connection 53. In other words, the sealant 16 is bonded to both the opposing surface 54a of the flange 54 and the outer surface 130 of the exterior wall material 13.

[0046] A portion of the sealant 16 provided between the flange 54 and the exterior wall material 13 may flow into the gap between the connection portion 53 and the exterior wall material 13. As described above, the bond breaker 55 is provided at the portion of the connection portion 53 that faces the exterior wall material 13. This prevents the sealant 16 that has flowed into the gap between the connection portion 53 and the exterior wall material 13 from coming into contact with the connection portion 53.

[0047] <Building construction method> The construction method for the building 10 includes a bond breaker installation process in which a bond breaker 55 is provided at the connection portion 53 of the accessory mounting member 15, and an accessory installation process in which the accessory mounting member 15 is attached to the exterior wall 11. The bond breaker installation process is performed before the accessory installation process. In this embodiment, the bond breaker installation process is performed at the factory where the accessory mounting member 15 is manufactured.

[0048] [Operation of this embodiment] The operation of this embodiment will be described. The building 10 includes an exterior wall 11 having a structural member 12 and an exterior wall member 13 disposed on the exterior side of the structural member 12. Because the exterior wall member 13 moves relative to the structural member 12 due to an earthquake or the like, if an accessory 100 is attached directly to the exterior wall member 13, there is a risk that the accessory 100 will fall from the exterior wall member 13. In this embodiment, the building 10 includes an accessory mounting member 15 for attaching the accessory 100 to the exterior side of the exterior wall 11. The accessory mounting member 15 has a fixing portion 51 fixed to the structural member 12, a mounting portion 52 located on the exterior side of the exterior wall member 13 and to which the accessory 100 is attached, and a connecting portion 53 connecting the fixing portion 51 and the mounting portion 52. Because the accessory mounting member 15 is fixed to the structural member 12, the mounting strength of the accessory 100 can be improved compared to when the accessory mounting member 15 is attached to the exterior wall member 13.

[0049] A sealant 16 is provided between the accessory mounting member 15 and the exterior wall material 13. If the accessory mounting member 15 does not have a flange 54, a triangular seal is formed between the outer peripheral surface of the connection portion 53 and the outer surface 130 of the exterior wall material 13. In contrast, the accessory mounting member 15 of this embodiment has a flange 54 that protrudes in a direction intersecting the extension direction of the connection portion 53 at a portion of the connection portion 53 that is located outside of the exterior wall material 13. A sealant 16 is provided between the flange 54 and the exterior wall material 13. This improves the waterproofing between the accessory mounting member 15 and the exterior wall material 13 compared to when a triangular seal is formed between the accessory mounting member 15 and the exterior wall material 13.

[0050] [Effects of this embodiment] The effects of this embodiment will be described. (1) The accessory mounting member 15 has a fixing portion 51 that is fixed to the structural material 12, a mounting portion 52 that is located outside the exterior wall material 13 and to which the accessory 100 is attached, and a connecting portion 53 that connects the fixing portion 51 and the mounting portion 52. A flange 54 that protrudes in a direction that intersects with the extension direction of the connecting portion 53 is provided at a portion of the connecting portion 53 that is located outside the exterior wall material 13. A sealing material 16 is provided between the flange 54 and the exterior wall material 13.

[0051] According to this configuration, the accessory mounting member 15 is fixed to the structural material 12, and therefore the mounting strength of the accessory 100 can be improved compared to when it is fixed to the exterior wall material 13. Furthermore, a flange 54 is provided at the connection portion 53, and a sealant 16 is provided between the flange 54 and the exterior wall material 13. This improves the waterproofing between the accessory mounting member 15 and the exterior wall material 13 compared to when a triangular seal is provided between the accessory mounting member 15 and the exterior wall material 13.

[0052] (2) The flange 54 is provided around the entire circumference of the connecting portion 53 when viewed from the direction in which the connecting portion 53 extends. With this configuration, the sealing material 16 can be provided between the flange 54 and the exterior wall material 13 around the entire circumference of the connecting portion 53 when viewed from the direction in which the connecting portion 53 extends. Therefore, the waterproofing between the accessory mounting member 15 and the exterior wall material 13 can be further improved.

[0053] (3) The connecting portion 53 is inserted into the joint G of the exterior building material 13. With this configuration, it is not necessary to provide a through-hole in the exterior building material 13 for inserting the connecting portion 53 therethrough. (4) The structural member 12 has a beam 22. The beam 22 has a web 24, a lower flange 25 located below the web 24, an upper flange 26 located above the web 24, and a stiffener 27 connecting the web 24, the lower flange 25, and the upper flange 26. The joints G of the exterior wall materials 13 have vertical joints G1 provided between adjacent exterior wall materials 13 in the first direction X. In the first direction X, the stiffeners 27 and the vertical joints G1 are provided at the same positions. The connecting portion 53 of the second accessory mounting member 15b has a base 531 inserted into the vertical joint G1 and a shift portion 532 connecting the base 531 and the fixing portion 51 so that the position of the fixing portion 51 is shifted relative to the base 531 in the first direction X. The fixing portion 51 is fixed to the stiffener 27 in a state where it is disposed along one end face 27b of the stiffener 27 in the first direction X.

[0054] In the case where the stiffener 27 and the vertical joint G1 are provided at the same position in the first direction X and the connecting portion 53 is inserted into the vertical joint G1, if the connecting portion 53 and the fixing portion 51 are provided at the same position in the first direction X, the fixing portion 51 will interfere with the stiffener 27. In contrast, in the present embodiment, the shift portion 532 shifts the position of the fixing portion 51 relative to the base portion 531 in the first direction X, so that interference of the fixing portion 51 with the stiffener 27 can be prevented. The fixing portion 51 is fixed to the stiffener 27 in a state where it is disposed so as to be along one end face 27b of the stiffener 27 in the first direction X. Therefore, the fixing portion 51 can be stably fixed to the stiffener 27.

[0055] (5) The structural member 12 has a column 21. The column 21 is composed of two C-shaped steels 23. The fixing portion 51 of the first incidental object mounting member 15a is fixed to the column 21 while being disposed between the two C-shaped steels 23. With this configuration, the first incidental object mounting member 15a can be firmly fixed to the column 21.

[0056] (6) The connecting portion 53 has an inclined portion 53a that slopes downward from the fixed portion 51 toward the mounting portion 52. With this configuration, even if moisture does infiltrate between the accessory mounting member 15 and the exterior wall material 13, the moisture is guided to the outdoors by the inclined portion 53a. Therefore, moisture is less likely to infiltrate indoors.

[0057] (7) A bond breaker 55 is provided in the connection 53 at a portion located indoors of the flange 54 and outdoors of the exterior building material 13. With this configuration, the bond breaker 55 prevents the sealant 16 provided between the flange 54 and the exterior building material 13 from coming into contact with the connection 53. This allows the sealant 16 to be bonded to both the flange 54 and the exterior building material 13 on two sides, thereby extending the life of the sealant 16.

[0058] (8) The bond breaker 55 is further provided at the portion of the connection portion 53 facing the exterior wall material 13. This configuration prevents the sealant 16 that has flowed between the connection portion 53 and the exterior wall material 13 from coming into contact with the connection portion 53.

[0059] (9) The construction method for the building 10 includes a bond breaker installation step of installing a bond breaker 55 at the connection portion 53 of the accessory installation member 15, and an accessory installation step of installing the accessory installation member 15 to the exterior wall 11. For example, if the bond breaker installation step is performed after the accessory installation step, the exterior wall 11 will get in the way when installing the bond breaker 55 at the connection portion 53. In particular, it is difficult to install the bond breaker 55 at the portion of the connection portion 53 that faces the exterior wall material 13. In contrast, in this embodiment, the bond breaker installation step is performed before the accessory installation step. In this case, the exterior wall 11 will not get in the way when installing the bond breaker 55 at the connection portion 53, making the bond breaker installation step easier.

[0060] (10) The bond breaker installation process is performed at the factory of the accessory mounting member 15. In this case, on-site workers do not perform the bond breaker installation process, so that variations in the installation of the bond breaker 55 by on-site workers can be avoided.

[0061] (11) The pillar 21 is provided with a plurality of first fixing holes 23a in the vertical direction Z for fixing the accessory mounting member 15. This allows the accessory mounting member 15 to be installed at any height.

[0062] (12) When the accessory mounting member 15 is fixed to the exterior wall materials 13 so as to straddle multiple exterior wall materials 13, the locking of the exterior wall materials 13 is hindered by the accessory mounting member 15.
