Description

[Technical field]

[0001] The present invention relates to a mounting tool for mounting an object to an external mounting surface of a building, and to a building structure using this mounting tool. [Background technology]

[0002] Known as such a mounting tool is, for example, the support rack described in Patent Document 1. This support rack includes a base provided on the base and waterproof layer, a sheet laid on the top surface of the base, rod-shaped fasteners provided to extend from the base toward the structure (object to be mounted), and a cover member provided to cover from the outside the connection portion of the rod-shaped fasteners to the base and having a top plate portion through which the rod-shaped fasteners pass.

[0003] Such a support rack is thought to be assembled in the following procedure. First, the base is fixed onto the base and waterproof layer, and then a sheet is laid on the top surface of the base. Then, a cover member is attached to the rod-shaped fastener extending upward from the base so as to cover the connection with the base from the outside. Next, with the rod-shaped fastener penetrating the top plate of the cover member, a cover plate and a nut are inserted through the rod-shaped fastener, and the nut is tightened.

[0004] This brings the covering member and the sheet into close contact with each other, thereby preventing rainwater that has flowed down the outside of the covering member from penetrating into the inside of the covering member due to the close contact between the covering member and the sheet. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2014-181493 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, in the support rack described in Patent Document 1, the covering member and the sheet are not fixed, and the covering member is pressed against the sheet by a nut to prevent water from entering between the covering member and the sheet. Therefore, if the nut loosens or the covering member separates from the sheet, rainwater or the like may enter the covering member through the gap between the two, and the connecting portion of the rod-shaped fastener to the base portion may corrode. Corrosion of the rod-shaped fastener hinders stable support of the object to be attached.

[0007] The present invention has been made in consideration of the above problems, and has an object to provide a mounting tool that can effectively suppress corrosion due to water, and a building structure using this mounting tool. [Means for solving the problem]

[0008] In order to solve the above problem, a mounting tool according to the present invention is a mounting tool for mounting an object to be mounted on an external mounting surface of a building, the mounting tool comprising: a fixing part fixed to the mounting surface, and a mounting part extending to one side from the fixing part and to which the object to be mounted; a covering part covering the fixing part from one side when the mounting part is inserted; a pass regulating part surrounding the periphery of the mounting part; and a cover member covering an opening on one side of the pass regulating part when the mounting part is inserted, the cover member restricting water from entering between the covering part and the fixing part from one side through between the pass regulating part and the mounting part; and sealing means provided in a space formed around the mounting part by the covering part and the regulating member, the pass regulating part abutting against the covering part from one side and surrounding an end part on the other side of the mounting part, restricting water from passing between the covering part and the pass regulating part. The fixing portion has a first hole portion for passing the attached portion through and a second hole portion formed around the first hole portion, the attached portion has a head portion disposed in the first hole portion and a male screw portion extending to one side from the head portion, and the fixing portion is fixed to the attachment surface by a screw driven through the second hole portion. do.

[0009] According to the present invention, since the passage of water between the passage restriction portion and the covering portion is restricted by the sealing means, it is possible to restrict access of water from the surroundings to the base portion of the attachment portion relative to the fixed portion, and therefore it is possible to effectively restrict the base portion from corroding due to water coming into contact with the base portion.

[0010] In the mounting device, it is preferable that the sealing means comprises a sealing material which is filled into the space and hardens in a state connecting the mounting portion and the pass-regulating portion so as to regulate relative movement of the pass-regulating portion with respect to the mounting portion.

[0011] According to this configuration, since the sealing material is filled in the space, even if condensation occurs in the space, the root portion of the attached portion can be reliably protected by the sealing material. Furthermore, since the sealing material hardens in a state in which the attached portion and the pass-regulating portion are connected so that the relative movement of the pass-regulating portion with respect to the attached portion is restricted, the passage-regulating portion is restricted from moving away from the covering portion, and thus the intrusion of water into the space can be restricted. Therefore, the passage-regulating portion can be more effectively prevented from coming into contact with water and corroding the root portion. Moreover, the passage-regulating portion can be fixed to the covering portion by the sealing material for protecting the root portion of the attached portion. Therefore, the sealing material can be used both as a protective member and a fixing member.

[0012] In the mounting tool, it is preferable that the covering portion has an extension portion that extends outward beyond the peripheral edge portion of the fixing portion in the radial direction of the mounted portion.

[0013] According to this configuration, since the extension portion extends outward beyond the peripheral portion of the fixed portion, by fixing the extension portion to the mounting surface, it is possible to prevent water from entering between the fixed portion and the mounting surface, thereby effectively preventing water from entering the interior of the building.

[0014] The building structure of the present invention is a building structure comprising the mounting device and a mounting surface to which the mounting device is attached, and the extension portion is adhered to the portion of the mounting surface surrounding the mounted portion and outside the peripheral portion of the fixed portion.

[0015] According to this building structure, since the extension part is bonded to the mounting surface in a portion surrounding the mounted part and outside the peripheral edge of the fixed part, it is possible to more effectively prevent water from entering between the fixed part and the mounting surface, thereby more effectively preventing water from entering the interior of the building. Effect of the Invention

[0016] As described above, the mounting tool and building structure of the present invention can effectively prevent water from entering the interior of a building. [Brief description of the drawings]

[0017] [Figure 1] FIG. 2 is a cross-sectional view of a building structure of the present invention. [Diagram 2] FIG. 2 is a plan view of the building structure of FIG. 1. [Diagram 3] FIG. 2 is an exploded perspective view of the mounting member of FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. Note that the following embodiment is an example of the present invention, and is not intended to limit the technical scope of the present invention. In addition, the following describes the case where the present invention is applied to a building made of reinforced concrete, but the building to which the present invention is applied is not limited to a building made of reinforced concrete, and may be a wooden building.

[0019] Fig. 1 shows a vertical cross-sectional view of a building structure 1 according to an embodiment of the present invention. In the following description, the upper side of the paper in Fig. 1 (the outside of the building) will be referred to as one side, and the lower side of the paper (the inside of the building) will be referred to as the other side.

[0020] As shown in FIG. 1, a building structure 1 includes a mounting tool 10 for mounting an object to a building, and an exterior wall 90 having a mounting surface 98 to which the mounting tool 10 is attached.

[0021] The exterior wall 90 has a concrete material 92 that constitutes the interior of the building, a heat insulating material 94 that covers the concrete material 92 from the outside, and a sheet material 96 that covers the heat insulating material 94 from the outside. As the concrete material 92, for example, lightweight aerated concrete (ALC) is used.

[0022] The sheet material 96 is provided on the outer surface of the insulation material 94 to protect the concrete material 92 and the insulation material 94 from wind and rain. The mounting tool 10 is attached to a mounting surface 98, which is the outer surface of the sheet material 96.

[0023] The mounting device 10 has a mounting member 20 for mounting an object to be mounted on a building, a covering portion 40 that covers a portion of the mounting member 20 (a fixing portion 22 described below) from one side, a regulating member 50 that regulates the intrusion of water into the portion of the mounting member 20 from one side, and a sealing means 33 that regulates the passage of water between the covering portion 40 and the regulating member 50.

[0024] As shown in FIG. 1, the mounting member 20 has a fixing portion 22 that is fixed to a mounting surface 98, and a mounted portion 24 that extends to one side from the fixing portion 22 and to which an object to be mounted is attached.

[0025] The fixing portion 22 is fixed to the mounting surface 98 by the screws 5 driven through the holes 22b, and in this embodiment, a disk-shaped fixing portion is used. The shape of the fixing portion 22 is not limited to a disk shape, and may be, for example, a plate having a square shape when viewed from above.

[0026] 1 and 3, the fixing portion 22 has a hole 22a at the center thereof for passing the mounting portion 24 therethrough. (1st hole) In addition, a plurality of holes 22b are formed around the hole 22a in the fixing portion 22. (2nd hole) are formed in a row in the circumferential direction. With the fixing portion 22 placed on the mounting surface 98, the screws 5 are driven into the holes 22b and the mounting surface 98, whereby the fixing portion 22 is attached to the mounting surface 98.

[0027] The mounting portion 24 has a male threaded portion extending to one side from the fixing portion 22 for mounting an object to be mounted, and a head portion provided at an end of the male threaded portion. The mounting portion 24 is welded to the fixing portion 22 in a state in which the male threaded portion extends to one side from the fixing portion 22 and is inserted into the hole portion 22a from below so that the head portion is disposed within the hole portion 22a. The object to be mounted is attached to one end of the mounting portion 24.

[0028] The covering portion 40 covers the fixing portion 22 from one side in a state in which the attached portion 24 is inserted. The covering portion 40 is formed from the same material as the sheet material 96 so as to facilitate joining to the sheet material 96 described below. The covering portion 40 has a size that enables it to cover the entire fixing portion 22 from one side. The covering portion 40 is formed from a waterproof material.

[0029] Additionally, the covering portion 40 has an extension portion 42 that extends outward beyond the peripheral edge of the fixing portion 22 in the radial direction of the attached portion 24. As shown in Fig. 1, the extension portion 42 is joined to a sheet material 96 of the attachment surface 98 in a portion surrounding the attached portion 24 and outside the peripheral edge of the fixing portion 22. Specifically, the extension portion 42 is joined to the sheet material 96, which will be described later, by welding, an adhesive, or the like.

[0030] 3, a hole 322a is formed in the center of the covering part 40, through which the attached part 24 can be inserted. The covering part 40 is placed on one side of the fixed part 22 with the attached part 24 inserted into the hole 322a.

[0031] As shown in FIG. 1, the regulating member 50 has a pass-regulating portion 30 that surrounds the attached portion 24, a covering member 36 that closes the opening on one side of the pass-regulating portion 30 when the attached portion 24 is inserted, and a nut 38 for pressing the pass-regulating portion 30 from one side to the other, and prevents water from entering between the covering portion 40 and the fixed portion 22 from one side through between the pass-regulating portion 30 and the attached portion 24.

[0032] The passage regulating portion 30 is configured to be fixed to the fixed portion 22 in a state in which the passage regulating portion 30 surrounds the base portion of the attached portion 24 relative to the fixed portion 22 .

[0033] The passage regulating portion 30 is formed in a cylindrical shape in order to form a space S around the attached portion 24 on one side of the fixing portion 22 into which the sealing material 34 is to be filled.

[0034] The pass regulating portion 30 is disposed on one side of the fixed portion 22 so that its axis coincides with the axis of the attached portion 24. The pass regulating portion 30 used in this embodiment has a size capable of forming a space S that fits within the range of the fixed portion 22 in a plan view. Specifically, the diameter of the pass regulating portion 30 is smaller than the diameter of the fixed portion 22 as shown in FIG. 2. The pass regulating portion 30 has a size capable of forming a space S that can be disposed below the end of one side of the attached portion 24 in a side view. Specifically, the axial length of the pass regulating portion 30 is shorter than the axial length of the attached portion 24 as shown in FIG. 1. The material of the pass regulating portion 30 is, for example, polyvinyl chloride.

[0035] The covering member 36 is interposed between the nut 38 and the passage regulating portion 30 so that the nut 38 can press the passage regulating portion 30 against the other side while covering one opening of the passage regulating portion 30 from one side. Specifically, as shown in Fig. 3, the covering member 36 includes a covering plate 36a that covers the opening on one side of the passage regulating portion 30 from above, and a plurality of injection ports 36b that are formed in the covering plate 36a so as to open a part of the space S upward and that are used to fill the space S with the sealing material 34.

[0036] Furthermore, since the portion of the space S other than the injection port 36b is covered by the cover plate 36a, leakage of the sealant 34 from the space S during the operation of filling the space S with the sealant 34 through the injection port 36b can be prevented.

[0037] The nut 38 is a member for pressing and fixing the pass regulating portion 30 against the covering portion 40 from one side by screwing into the attached portion 24. As the nut 38 is screwed into the attached portion 24 and moves from one side to the other side, it presses the covering plate 36a of the covering member 36 to the other side, pressing the pass regulating portion 30 against the covering portion 40. This makes it possible to more firmly regulate the passage of water from one side between the attached portion 24 and the pass regulating portion 30, and to more firmly regulate the passage of water from the radial outside of the attached portion 24 between the pass regulating portion 30 and the covering portion 40.

[0038] 1, the sealing means 33 is a means for restricting the passage of water between the covering portion 40 and the passage restriction portion 30, which is in contact with the covering portion 40 from one side and surrounds the other end of the attached portion 24. The sealing means 33 is provided in a space S formed around the attached portion 24 by the covering portion 40 and the restriction member 50.

[0039] As shown in FIG. 1, the sealing means 33 has a sealing material 34 for protecting the base portion of the mounting portion 24 and for fixing the passage regulating portion 30 to the covering portion 40 .

[0040] The sealing material 34 is used to prevent water from entering the base of the attachment portion 24, and has the property of hardening over time. The sealing material 34 is filled into the space S of the pass regulation portion 30, and hardens in a state in which the attachment portion 24 and the pass regulation portion 30 are connected to each other so that the relative movement of the pass regulation portion 30 with respect to the attachment portion 24 is restricted.

[0041] The sealing material 34 may fill the entire space S or may fill only a part of the space S. When filling only a part of the space S with the sealing material 34, it is preferable to dispose the sealing material 34 over the boundary between the passage restriction portion 30 and the covering portion 40 so as to restrict the intrusion of water between the passage restriction portion 30 and the covering portion 40.

[0042] (Manufacturing method) A method for manufacturing the fastening tool 10 according to this embodiment will be described below.

[0043] The mounting member 20 is assembled by attaching the mounted portion 24 to the fixed portion 22. Specifically, as shown in FIG. 1, the male thread portion of the mounted portion 24 is inserted from below into the hole portion 22a of the fixed portion 22, and in this state, the other end portion of the mounted portion 24 is welded to the fixed portion 22.

[0044] Next, the covering portion 40 is placed on the fixing portion 22 with the attached portion 24 inserted into the hole 322 a of the covering portion 40 .

[0045] Next, the pass regulating portion 30 is attached to the mounting member 20. Specifically, the attached portion 24 is passed through the pass regulating portion 30 so that the axis of the pass regulating portion 30 and the axis of the attached portion 24 coincide with each other. Then, the other edge of the pass regulating portion 30 is brought into close contact with one surface of the covering portion 40.

[0046] Furthermore, the covering member 36 is inserted into the attached portion 24 to cover one side of the pass regulating portion 30, and the nut 38 is screwed into the attached portion 24. Then, the pass regulating portion 30 is pressed against the covering portion 40 as the nut 38 moves to the other side.

[0047] In this state, uncured sealant 34 is filled into space S formed by covering portion 40, attached portion 24, and pass regulating portion 30 through injection port 36b of covering member 36. This allows sealant 34 to be cured in a state in which attached portion 24 and pass regulating portion 30 are connected so that relative movement of pass regulating portion 30 with respect to attached portion 24 is regulated in a state before fixed portion 22 is fixed to mounting surface 98, and in a state in which pass regulating portion 30 is in close contact with one surface of fixed portion 22.

[0048] (Construction method) The method of application of the mounting tool 10 thus manufactured to the mounting surface 98 will now be described.

[0049] First, the mounting tool 10 is attached to the mounting surface 98. Specifically, the screw 5 is inserted into the hole 22b of the fixing portion 22 and then driven into the mounting surface 98, thereby fixing the fixing portion 22 to the mounting surface 98.

[0050] Next, the extension portion 42 is adhered to the surrounding portion of the fixed portion 22 on the attachment surface 98, all around the attached portion 24. The extension portion 42 may be joined to the attachment surface 98 by welding the extension portion 42 and the sheet material 96 together, in addition to using an adhesive.

[0051] An object to be attached is attached to the building structure 1 constructed in this manner, as described below.

[0052] The object to be attached has an attachment portion that can be screwed into the attached portion 24. For example, a solar cell module can be used as the object to be attached.

[0053] (Action and effect) According to the mounting tool 10 of this embodiment, the sealing means 33 restricts the passage of water between the passage restriction part 30 and the covering part 40, so it is possible to restrict the access of water from the surroundings to the base part of the mounted part 24 relative to the fixed part 22. This makes it possible to effectively prevent the base part from corroding due to water coming into contact with the base part.

[0054] In addition, since the space S is filled with the sealing material 34, the attachment portion 24 and the passage regulating portion 30 are connected by the sealing material 34. Therefore, even if the attachment portion 24 is inclined with respect to the fixing portion 22, the watertight performance can be maintained.

[0055] In addition, since the space S is formed adjacent to the covering portion 40, the sealant 34 can be filled in a state adjacent to the gap between the pass-regulating portion 30 and the covering portion 40. This makes it possible to prevent water from entering the base portion of the attached portion 24 through the gap between the pass-regulating portion 30 and the covering portion 40, and effectively prevents water from entering the interior of the building.

[0056] In addition, since the sealing material 34 is filled in the space S, even if condensation occurs in the space S, the sealing material 34 can reliably protect the root portion of the attachment portion 24. Since the sealing material 34 hardens in a state in which the attachment portion 24 and the pass-regulating portion 30 are connected so that the relative movement of the pass-regulating portion 30 with respect to the attachment portion 24 is restricted, the pass-regulating portion 30 is restricted from moving away from the covering portion 40, and thus the intrusion of water into the space S can be suppressed. Therefore, the corrosion of the root portion due to contact with water can be more effectively suppressed. Moreover, the pass-regulating portion 30 can be fixed to the covering portion 40 by the sealing material 34 for protecting the root portion of the attachment portion 24. Therefore, the sealing material 34 can be used as both a protective member and a fixing member.

[0057] In addition, since the sealant 34 hardens with the passage restriction portion 30 in close contact with one surface of the covering portion 40, it is possible to prevent water from entering from the outside through the gap between the passage restriction portion 30 and one surface of the covering portion 40. This makes it possible to more effectively prevent water from entering the interior of the building.

[0058] According to this configuration, the extension portion 42 extends outward beyond the peripheral edge of the fixed portion 22, and therefore, by fixing the extension portion 42 to the mounting surface 98, it is possible to prevent water from entering between the fixed portion 22 and the mounting surface 98. This makes it possible to effectively prevent water from entering the interior of the building.

[0059] In addition, since the extension portion 42 is adhered to the mounting surface 98 in the portion surrounding the mounted portion 24 and outside the peripheral edge of the fixed portion 22, it is possible to more effectively prevent water from entering between the fixed portion 22 and the mounting surface 98. This makes it possible to more effectively prevent water from entering the interior of the building.

[0060] (Modification) The above-described embodiments are merely illustrative of preferred specific examples of the present invention, and the present invention is not limited to the above-described embodiments.

[0061] In the above embodiment, the mounting portion 24 is welded to the fixed portion 22, but the method of fixing the mounting portion 24 to the fixed portion 22 is not limited to welding. For example, the mounting portion 24 may be fixed to the fixed portion 22 by crimping the other end of the mounting portion 24 into the hole 22a of the fixed portion 22.

[0062] In the above embodiment, the sealing material 34 is filled in the space S as the sealing means 33, but the sealing means 33 is not limited to this. For example, in order to restrict the passage of water between the passage restriction portion 30 and the covering portion 40, the sealing material 34 may be applied across the passage restriction portion 30 and the covering portion 40, or a tape may be attached across the passage restriction portion 30 and the covering portion 40.

[0063] In the above embodiment, the uncured sealant 34 is filled into the space S through the injection port 36b with one side of the pass regulating portion 30 covered by the covering member 36, but the timing for filling the space S with the sealant is not limited to this. For example, the sealant 34 may be filled into the space S before covering one side of the pass regulating portion 30 with the covering member 36, and then the one side of the pass regulating portion 30 may be covered with the covering member 36.

[0064] In addition, in the above embodiment, the sealant 34 is filled into the space S before the mounting tool 10 is attached to the mounting surface 98, but the timing for filling the space S with the sealant 34 is not limited. For example, the sealant 34 may be filled into the space S after the fixing part 22 is attached to the mounting surface 98.

[0065] In the above embodiment, a solar cell module is exemplified as the mounting object, but the mounting object to be attached to the mounting tool 10 is not limited to a solar cell module. For example, a parabolic antenna can be used as the mounting object.

[0066] In the support rack described in Patent Document 1, the cover member and the base are not fixed, and the cover member is pressed against the base by a nut, thereby preventing water from entering between the cover member and the base. Furthermore, the connection portion of the rod-shaped fastener to the base is covered only by the cover member. Therefore, if the cover member separates from the base due to the nut loosening, rainwater or the like may enter the cover member through the gap between the two, causing the connection portion of the rod-shaped fastener to corrode. Corrosion of the rod-shaped fastener hinders stable support of the object to be attached.

[0067] In contrast to such Patent Document 1, the mounting tool 10 according to the above embodiment can be considered to have the following configuration. In other words, the mounting tool 10 of the invention is a mounting tool 10 for mounting an object to a mounting surface 98 on the outside of a building, and includes a mounting member 20 having a fixing part 22 fixed to the mounting surface 98 and an attached part 24 extending from the fixing part 22 to one side and to which the object is attached, a pass-restricting mechanism surrounding the attached part 24 so as to restrict the passage of water from one side between the fixing part 22 and the attached part 24, and a surrounding covering part (a part of the covering part 40 that is not pass-restricting in a plan view) that extends from the pass-restricting mechanism around the attached part 24 and covers the fixing part 22 from one side. and a water intrusion prevention member that prevents water from intrusion from one side through between the pass-restriction mechanism and the mounting portion 24 into the space between the surrounding covering portion and the fixed portion 22, the pass-restriction mechanism having a forming member (pass-restriction portion 30) for forming a space S around the mounting portion on one side thereof for filling with sealing material 34, and the pass-restriction mechanism is configured to be fixed to the fixed portion 22 in a state surrounding the base portion of the mounting portion 24 relative to the fixed portion 22.

[0068] According to this configuration, the pass-restricting mechanism has a forming member (pass-restricting portion 30) for forming a space S around the attached portion 24 on one side of the fixed portion 22 for filling the sealing material 34, and by filling the space S with the sealing material 34, it is possible to prevent water from accessing the attached portion 24 from the surroundings. Moreover, the pass-restricting mechanism can be fixed to the fixed portion 22 in a state in which the pass-restricting mechanism surrounds the base portion of the attached portion 24 relative to the fixed portion 22. Therefore, by fixing the pass-restricting mechanism to the fixed portion 22, not only can the intrusion of water through between the pass-restricting mechanism and the fixed portion 22 be prevented, but even if water does intrude, the base portion of the attached portion 24 can be reliably protected by the sealing material 34. Therefore, it is possible to effectively prevent the base portion from coming into contact with water and corroding.

[0069] The forming member may be only the passage regulating portion 30, or may include the passage regulating portion 30 and a portion of the covering portion 40 that overlaps with the passage regulating portion 30 in a plan view. Furthermore, the forming member may include a covering member 36 in addition to the passage regulating portion 30.

[0070] The sealing material 34 may fill the entire space S or may fill only a part of the space S. When filling only a part of the space S with the sealing material 34, it is preferable to dispose the sealing material 34 so as to surround the periphery of the attached portion 24 (particularly the periphery of the base portion) in order to protect the base portion.

[0071] Needless to say, various other design modifications are possible within the scope of the claims of the present invention. [Explanation of symbols]
