Description

[Technical Field]

[0001] The present invention relates to a mounting structure for a wall-mounted body. [Background technology]

[0002] Conventionally, there has been known a mounting structure for a wall-mounted body in which a eaves member (wall-mounted body) is mounted to an exterior wall that has an exterior wall material on the outdoor side of the substrate using screws that are screwed into the substrate (see, for example, Patent Document 1). In this mounting structure, a base plate is attached to a substrate material made of wood or the like, and a mounting member for the eaves member is fixed to the exterior wall using a bolt that penetrates the exterior wall material and is screwed into the base plate. At this time, the mounting member for the eaves member fixed by the bolt is clamped between the exterior wall and the head of the bolt. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2023-98778 Summary of the Invention [Problem to be solved by the invention]

[0004] Because wall-mounted structures such as eaves members are attached by overhanging the exterior wall, when the weight of snow or other factors acts on them, the lower end of the mounting member is pressed toward the substrate along with the exterior wall material to which the bolts are not threaded. In this case, the lower end of the mounting member separates from the heads of the bolts, which are threaded into the substrate and do not move, and moves toward the substrate along with the exterior wall. Alternatively, when the wall-mounted structure is blown by an upward wind, the upper end of the mounting member is pressed toward the substrate along with the exterior wall material, separates from the bolt heads, and moves toward the substrate along with the exterior wall. When the mounting member separates from the bolt heads, creating a gap between the mounting member and the bolt heads, the mounting portion becomes loose, resulting in an unstable installation of the wall-mounted structure. This problem is particularly prevalent when there is a space between the substrate and the exterior wall, or inside the exterior wall.

[0005] The present invention has been made in consideration of such problems, and its purpose is to provide a mounting structure for a wall-mounted body that is less likely to become unstable even when an external force is applied to the wall-mounted body. [Means for solving the problem]

[0006] The main invention for achieving this object is a mounting structure for a wall-mounted body, which is attached to an exterior wall having an exterior wall material on the outdoor side of a base by a screw that is screwed into the base, the wall-mounted body is in contact with the exterior wall material and has a fastened member through which the screw passes and into which the head of the screw abuts; The fastened member is restricted from moving in the axial direction of the screw relative to the head of the screw.

[0007] Other features of the present invention will become apparent from the description of this specification and the accompanying drawings. [Effects of the Invention]

[0008] According to the present invention, it is possible to provide a mounting structure for a wall-mounted body in which the mounting state is less likely to become unstable even when an external force is applied to the wall-mounted body. [Brief explanation of the drawings]

[0010] An embodiment of the mounting structure for a wall-mounted body of the present invention will be described with reference to the drawings. In this embodiment, an example of the wall-mounted body will be described, taking as an example a canopy 1 that is attached to the exterior wall of a building so as to protrude from the exterior wall.

[0011] The exterior wall 2 to which the eaves 1 of this embodiment is attached has, as shown in Figure 1, a base 20 having a main body 20a and a structural panel 20b abutted against the outdoor side of the main body 20a, and an exterior wall material 21 provided on the outdoor side of the base 20 via an air layer S.

[0012] The eaves 1 has an eaves body 10 that protrudes from and is attached to the exterior wall 2, and a fastening member 11 for fixing the eaves body 10 to the exterior wall 2, and the eaves body 10 is fixed and attached by a bolt 4 to the fastening member 11 that is attached to the exterior wall 2 by a screw 3.

[0013] The fastened members 11 include an upper fastened member 12 arranged above the eaves main body 10, and a lower fastened member 13 arranged below the eaves main body 10. The upper fastened member 12 and the lower fastened member 13 are both extruded members. The upper fastened member 12 includes an upper eaves abutment portion 12a that extends outdoors and abuts the top of the eaves main body 10, an upper exterior wall abutment portion 12b that extends upward from the exterior wall end of the upper eaves abutment portion 12a and abuts against the exterior wall 2, a middle / exterior wall abutment portion 12c that extends downward from the exterior wall end of the upper eaves abutment portion 12a and abuts against the exterior wall 2, and an upper engagement portion 12d that is provided at the lower end of the middle / exterior wall abutment portion 12c and engages with the lower fastened member 13.

[0014] The lower fastening member 13 has a lower eaves abutment portion 13a that extends outdoors and abuts against the underside of the eaves main body 10, a lower outer wall abutment portion 13b that extends downward from the outer wall side end of the lower eaves abutment portion 13a and abuts against the outer wall 2, and a lower engagement portion 13c that is provided at the upper end of the lower outer wall abutment portion 13b and engages with the upper engagement portion 12d.

[0015] When the upper engaging portion 12d of the upper fastened member 12 and the lower engaging portion 13c of the lower fastened member 13 are engaged, the outer wall side surfaces of the upper outer wall abutting portion 12b, the middle outer wall abutting portion 12c and the lower outer wall abutting portion 13b are flat and abut against the surface of the exterior wall material 21, and the fastened member 11 is attached by screws 3 that pass through the upper outer wall abutting portion 12b, the middle outer wall abutting portion 12c and the lower outer wall abutting portion 13b respectively and are screwed into the main body 20a.

[0016] A cylindrical spacer 5 is inserted into each screw 3, and the spacer 5 penetrates the exterior wall material 21, with one end abutting against one of the upper exterior wall abutting portion 12b, the middle exterior wall abutting portion 12c, or the lower exterior wall abutting portion 13b, and the other end abutting against the structural panel 20b. In other words, the spacer 5 is provided so as to maintain the distance between the structural panel 20b and one of the upper exterior wall abutting portion 12b, the middle exterior wall abutting portion 12c, or the lower exterior wall abutting portion 13b. If the exterior wall material has a hollow portion, the spacer 5 is attached in a state where it is sandwiched between the exterior-most board portion of the exterior wall material and the substrate.

[0017] In addition, a restricting member 6 is attached to the head side of each screw 3 to restrict the movement of the upper outer wall abutment portion 12b, the middle outer wall abutment portion 12c, and the lower outer wall abutment portion 13b in the axial direction of the screw 3 relative to the head 3a of the screw 3.

[0018] In the following explanation, the fastened members are shown schematically in Figures 2 to 4, and the fastened member 14 in Figures 2 to 4 has an exterior wall abutting portion 14a that abuts against the exterior wall material 21, has a U-shaped vertical cross section, and is attached by a screw 3 that is screwed into the main body 20a. The exterior wall abutting portion 14a corresponds to the upper exterior wall abutting portion 12b and middle exterior wall abutting portion 12c of the upper fastened member 12, and the lower eaves abutting portion 13a of the lower fastened member 13.

[0019] 2 and 5, the restricting member 6 has a facing plate portion 6a facing the outer wall abutting portion 14a with a gap therebetween, a pair of extending plate portions 6b extending from both longitudinal ends of the fastened member 14 on the facing plate portion 6a toward the outer wall abutting portion 14a, and fixing plate portions 6c extending from the ends of the pair of extending plate portions 6b on the outer wall abutting portion 14a side in opposite directions to the directions in which they face each other and fixed to the outer wall abutting portion 14a. Each of the two fixing plate portions 6c has an opening 6d through which a screw 7 passes, and the restricting member 6 is fixed by the screw 7 that passes through the opening 6d and is screwed into the outer wall abutting portion 14a.

[0020] The restricting member 6 is attached so that the fixing plate portions 6c are located on both sides of the head 3a of the screw 3 that attaches the fastened member 14 to the exterior wall 2 in the longitudinal direction of the fastened member 14, and the facing plate portion 6a abuts or is close to the head 3a of the screw 3, covering the head 3a from the outdoors side. Here, the facing plate portion 6a corresponds to the head-facing portion. By attaching the restricting member 6, the movement of the fastened member 14 in the axial direction of the screw 3 is restricted, so the fastened member 14 cannot move away from the head 3a of the screw 3 and move or deform toward the base 20.

[0021] According to the mounting structure of the wall-mounted body of this embodiment, the fastened member 14 of the eaves 1 is abutted against the exterior wall material 21, and the head 3a of the screw 3 that penetrates the fastened member 14 and screws into the main body 20a is abutted against it, and the movement of the screw 3 in the axial direction relative to the head 3a is restricted by a regulating member 6 that is fixed to the fastened member 14 and whose facing plate portion 6a faces the head 3a on the outdoor side.

[0022] For this reason, even if an external force acts in the vertical direction on the eaves 1 that is attached and protrudes from the exterior wall material 21, and a force acts on the upper and lower ends of the part of the fastened member 14 that abuts against the exterior wall material 21, pressing it together with the exterior wall material 21 toward the base 20, the exterior wall material 21 will not deform and move away from the head 3a of the screw 3 toward the base 20. For this reason, even if an external force acts in the vertical direction on the eaves 1, it is unlikely that a gap will form between the fastened member 14 and the head 3a of the screw 3, so the wall-mounted body will remain stably fixed by the screw, and it is possible to prevent the attachment state of the eaves 1 from becoming unstable.

[0023] Furthermore, because there is a spacer 5 between the base 20 and the fastened member 14, through which the screw 3 is inserted and clamped, it is possible to maintain the distance between the base 20 and the fastened member 14, even in an exterior wall structure in which an air gap S is provided between the base 20 and the fastened member 14. Furthermore, when an external force is applied to the eaves 1 in the vertical direction, the exterior wall material 21 does not deform by separating from the head 3a of the screw 3, so the base 20 is less likely to be pressed locally by the spacer 5 and therefore less likely to be crushed. Therefore, it is possible to maintain a stable attachment state supported by the spacer 5.

[0024] In the above embodiment, an example was described in which the restricting member 6 has fixing plate portions 6c on both sides of the facing plate portion 6a, but the fixing plate portion 6c may be provided on only one side as long as it is possible to restrict the movement of the screw 3. Also, as shown in Figures 6 and 7, a hook portion 14b may be provided along the longitudinal direction of the fastened member 14, and one side of the facing plate portion 6a of the restricting member 6 may be fixed by the screw 7, and the other side may be attached to the restricting member 6 by being engaged with the hook portion 14b.

[0025] Furthermore, as shown in Figure 8, the screw 3 may have a disk-shaped flange 3c on the threaded portion 3b side of the head 3a, and as shown in Figure 9, the screw 7 inserted into the through hole 3d provided in the flange 3c may be threaded into the fastened member 14, thereby restricting the axial movement of the fastened member 14 and the screw 3.

[0026] In the above embodiment, an eave 1 that protrudes from an exterior wall and is attached to the wall has been used as an example of a wall-mounted body, but this is not limited to this, and the wall-mounted body may also be a roof, a clothesline, a balcony floor, etc. that protrudes from an exterior wall and is attached to the wall.

[0027] The above-described embodiments are provided to facilitate understanding of the present invention and are not intended to limit the present invention. The present invention may be modified or improved without departing from the spirit thereof, and the present invention includes equivalents thereof.

[0028] The present embodiment includes at least the following inventions. Aspect 1: An installation structure for a wall-mounted body in which a wall-mounted body is attached to an exterior wall having an exterior wall material on the outdoor side of the base by a screw that is screwed into the base, wherein the wall-mounted body abuts against the exterior wall material and has a fastened member through which the screw passes and against which the head of the screw abuts, and the fastened member is restricted in movement in the axial direction of the screw relative to the head.

[0029] According to the mounting structure of the wall-mounted body of the first aspect, the fastened member of the wall-mounted body abuts against the exterior building material, and the head of the screw that penetrates the fastened member and screws into the base abuts against the fastened member, restricting its axial movement relative to the head. Therefore, even if an external force acts in the vertical direction on the wall-mounted body that protrudes from the exterior building material and the upper or lower end of the fastened member abutting the exterior wall attempts to move toward the base material along with the exterior building material, the fastened member is restricted from moving relative to the head, preventing it from moving toward the base material. Therefore, even if an external force acts in the vertical direction on the wall-mounted body, the exterior building material does not deform and separate from the screw head. This reduces the likelihood of a gap forming between the fastened member and the screw head, maintaining the wall-mounted body stably fixed by the screw and preventing the mounting state from becoming unstable.

[0030] Aspect 2: The mounting structure for a wall-mounted body according to Aspect 1, characterized in that it has a spacer that is sandwiched between the base and the fastened member and through which the screw is inserted.

[0031] The mounting structure of the wall-mounted body of the second embodiment has a spacer through which the screw is inserted and sandwiched between the base and the fastened member. Therefore, even in an exterior wall structure where there is a gap between the base and the fastened member, it is possible to maintain the distance between the base and the fastened member. Furthermore, when an external force acts on the wall-mounted body in the vertical direction, the exterior wall material does not deform by separating from the screw head, so the base is less likely to be pressed locally by the spacer and to be crushed. Therefore, the support provided by the spacer makes it possible to maintain a stable mounting state.

[0032] Aspect 3: The mounting structure of the wall-mounted body according to Aspect 1 or Aspect 2, further comprising a restricting member having a head-facing portion facing the head on the outdoor side of the head, and fixed to the fastened member; The fastened member is characterized in that movement of the fastened member in the axial direction of the screw is restricted by the restricting member.

[0033] According to the mounting structure of the wall-mounted body of the third aspect, the restricting member fixed to the fastened member has a head-facing portion that faces the head on the outdoor side of the head, so when the fastened member tries to move away from the head toward the base material, the head-facing portion abuts against the head, preventing the fastened member from moving toward the base material. This makes it possible to more reliably prevent a gap from occurring between the mounting member and the bolt head.

[0034] Aspect 4: The mounting structure for a wall-mounted body according to Aspect 1 or Aspect 2, characterized in that the head is fixed to the fastened member.

[0035] According to the mounting structure of the wall-mounted body of the fourth aspect, the head is fixed to the fastened member, so even if the fastened member tries to move away from the head toward the base material, the fastened member cannot move toward the base material. This makes it possible to more reliably prevent a gap from occurring between the mounting member and the bolt head. [Explanation of symbols]
