Description

[Technical field]

[0001] The present invention relates to an arrangement body fixing structure and a fixing bracket used when fixing an arrangement body onto a floor portion of a building frame. [Background technology]

[0002] Along with the demand for higher durability of buildings, many buildings are adopting sheet waterproofing structures in which waterproof sheets (resin sheets) are laid and constructed on their rooftops, verandas, and other body parts (structural parts) (see, for example, Patent Document 1).

[0003] In this sheet waterproofing structure, when insulation is laid on the floor, for example, at least a portion of the insulation laid on the floor is covered with a waterproof sheet, and the waterproof sheet is fixed to the floor (main body) via the insulation as follows, for example. That is, first, multiple disk-shaped fixed disks (steel plates) are placed on the insulation at a predetermined interval and fixed to the floor via the insulation using fixing screws or the like. Furthermore, the upper surface of each of these fixed disks is joined to the lower surface of the waterproof sheet, thereby joining the floor and the waterproof sheet via the fixed disks placed on the insulation.

[0004] In recent years, it has been proposed to install an arrangement such as a solar panel unit on a structure provided with such a sheet waterproofing structure (see, for example, Patent Document 2).

[0005] In this case, the fixing bracket (fixing anchor) is fixed to the floor (flat surface) on which the waterproof sheet is laid by driving the column-shaped body of the fixing bracket into the floor, and then the legs of the solar panel unit (mounting body) are fixed to this fixing bracket, thereby installing the solar panel unit on a structure with a sheet waterproofing structure.

[0006] Here, when installing such an arrangement such as a solar panel unit on a main body, as described above, it becomes necessary to fix the fixing brackets to the floor portion of the main body, and to achieve this, it becomes necessary to drive the column-shaped bodies of the fixing brackets into the floor portion.

[0007] In this case, the floor into which the columns are driven is composed of flat plates such as autoclaved lightweight aerated concrete (ALC) panels or extruded cement board (ECP). Various configurations are envisaged, such as a case in which this flat plate is joined to the main structure of the building structure, or a case in which the floor itself is composed of reinforced concrete.

[0008] As a result, currently, fixing hardware that is suitable for each type of floor structure is prepared, and from the standpoint of reducing the number of parts that need to be brought to the work site, there has been a demand for the development of more versatile fixing hardware.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an arrangement fixing structure and a fixing metal fitting according to the present invention will be described in detail based on preferred embodiments shown in the accompanying drawings.

[0024] First, before describing the arranging body fixing structure and fixing metal fittings of the present invention, a solar panel unit (photovoltaic power generation unit) fixed to a frame having a sheet waterproofing structure via the arranging body fixing structure (fixing metal fittings) of the present invention will be described. In other words, a case will be described in which a solar panel unit is applied as an arranging body fixed to a frame having a sheet waterproofing structure via the arranging body fixing structure of the present invention.

In the following description, the upper side in Fig. 1 to Fig. 5(a) is referred to as "top" and the lower side as "bottom", while the front side of the paper in Fig. 5(b) to Fig. 7 is referred to as "top" and the back side of the paper is referred to as "bottom". Also, for the sake of convenience, Fig. 1 does not show the entire structure to which the sheet waterproofing structure is applied, but only partially illustrates the floor and wall parts of the structure. Furthermore, in Fig. 2 to Fig. 5(a), the thickness direction of each part of the solar panel unit, the sheet waterproofing structure, and the locator fixing structure are exaggerated and illustrated typically to facilitate understanding.

[0026] The solar panel unit 70 is fixed to a frame 10 (structural body) such as a rooftop or a balcony on which the sheet waterproofing structure 1 is installed.

[0027] In this embodiment, as shown in FIG. 1, the frame 10 has a floor portion 11 and a wall portion 12 (rising portion) that is provided upright along the outer edge of the floor portion 11 so as to surround it.

[0028] Depending on the type of structure 10, floor 11 and wall 12 are each constructed of flat plates such as autoclaved lightweight aerated concrete (ALC) panels or extruded cement boards (ECP), and these flat plates may be joined to a main structure (not shown) of structure 10, or floor 11 and wall 12 themselves may be constructed of reinforced concrete.

[0029] The sheet waterproofing structure 1 is constructed as described above on a structure 10, i.e., a structure 10 having a wall portion 12 forming a frame and a floor portion 11 forming the bottom, and has an insulating layer 40 (insulating material) laid on the upper side of the floor portion 11, a waterproof sheet 30 laid on the wall portion 12 and the insulating layer 40, a positioning member (not shown), and a fixing disk (not shown).

[0030] The heat insulating layer 40 (thermal insulating material) has an overall sheet-like (layered) shape and is laid on the upper side of the floor 11, with its lower surface abutting the floor 11 and its upper surface abutting the waterproof sheet 30 described below. This allows the heat insulating layer 40 to function as a barrier against the transfer of heat from the outside to the inside of the structure 10.

[0031] The heat insulating layer 40 is made of a foam, and examples of its constituent materials include resin materials such as thermoplastic resins and thermosetting resins, metal materials, and ceramic materials, and one or a combination of two or more of these can be used as the main material, but it is preferable that the main material is a thermoplastic resin. This reduces the weight of the heat insulating layer 40, and by using a chemical or physical method, the heat insulating layer 40 made of a foam can be formed relatively easily.

[0032] In this specification, the term "main material" refers to a constituent material that is contained in an amount of 50% by weight or more among the constituent materials that constitute the layer (film) that contains this substance.

[0033] The thermoplastic resin is not particularly limited, but examples thereof include polyolefin-based resins such as polyethylene, polypropylene, and ethylene-vinyl acetate copolymers, polyester-based resins, polystyrene-based resins, polycarbonate-based resins, and polyurethane-based resins, and one or more of these may be used in combination.

[0034] As described above, the heat insulating layer 40 may be composed of a single foam, or may be a laminate in which the upper surface of the foam is covered with a covering material. By covering the foam with a covering material in this way, the plasticizer contained in the waterproof sheet 30 described later can be reliably prevented from migrating to the foam, so that the deterioration and degradation of the waterproof sheet 30 can be more appropriately suppressed or prevented.

[0035] Examples of the covering material include insulating cloth sheets made of woven polyethylene fabric, fireproof sheets made of glass fiber, and aluminum foil laminate sheets for pinhole inspection.

[0036] Furthermore, the average thickness of the heat insulating layer 40 is preferably about 30 mm to 100 mm, and more preferably about 40 mm to 70 mm, so that the heat insulating layer 40 can reliably perform the function of blocking the transfer of heat from the outside to the inside of the structure 10.

[0037] The positioning member (not shown) is placed at the boundary between the wall portion 12 and an insulating layer 40 laid on the floor portion 11, and further, a plurality of fixed disks (not shown) are placed on the insulating layer 40 at a predetermined (constant) interval. In this state, the positioning member and the fixed disks are fixed to the floor portion 11 via the insulating layer 40 by fixing screws or the like.

[0038] The waterproof sheet 30, which is primarily made of a resin material such as polyvinyl chloride resin and preferably contains additives such as plasticizers, stabilizers, antioxidants, UV absorbers, processing aids, lubricants, fillers, flame retardants and colorants, is fixed to the fixing members and fixing disks by welding or adhesive, covering the floor portion 11 and the insulating layer 40 together with the positioning members, fixing disks and fixing screws configured as described above, thereby ensuring the waterproofing of the main body 10.

[0039] That is, the waterproof sheet 30 is exposed to sunlight and rainwater, and the structure 10 is prevented from being directly exposed to sunlight and rainwater, thereby ensuring the waterproofness of the structure 10. Also, the upper surface of the fixing disk is joined to the lower surface of the waterproof sheet 30, and this joins the floor part 11, on which the insulating layer 40 is laid, and the waterproof sheet 30 via the fixing disk, so that the waterproof sheet 30 is fixed to the structure 10 without being torn off by wind, etc.

[0040] The waterproof sheet 30 preferably has an average thickness of about 0.5 mm to 5.0 mm, and more preferably about 1.0 mm to 2.5 mm, so that the waterproof sheet 30 can reliably perform the function of ensuring the waterproofness of the body 10.

[0041] 1 and 2, the solar panel unit 70 is an arrangement body fixed to the structure 10 provided with the sheet waterproofing structure 1 having the thermal insulation layer 40, and has a flat body 71 (solar panel portion) and four legs 72 protruding downward from the vicinity of each corner of the body 71, and in this embodiment, a plurality of solar panel units 70 (six in FIG. 1) are arranged in a matrix on the structure 10 provided with the sheet waterproofing structure 1. The solar panel unit 70 is fixed to the floor 11 (structure 10) provided with the sheet waterproofing structure 1 by its legs 72 via fixing brackets 50 provided on the arrangement body fixing structure 60.

[0042] The main body 71 has a plurality of cells, for example made of polycrystalline silicon, arranged in a matrix and covered with tempered glass; in this embodiment, it is a flat plate having a rectangular shape when viewed from above, with legs 72 protruding from the vicinity of the four corners of its underside.

[0043] Four legs 72 are provided for one main body 71, each of which has a rod-like overall shape, a base end fixed near a corner of the main body 71, and a tip fixed to the floor 11 of the structure 10 to which the sheet waterproofing structure 1 is applied via a fixing bracket 50 provided in the arrangement body fixing structure 60. Such legs 72 are formed such that two legs 72 are longer than the other two legs 72, and the two long legs 72 are arranged near a corner corresponding to one long side, and the two short legs 72 are arranged near a corner corresponding to the other long side. This allows the main body 71 to be inclined with respect to the floor 11 when the solar panel unit 70 is fixed to the structure 10, so that the main body 71 can efficiently receive sunlight by fixing the inclined main body 71 to the structure 10 while facing south.

[0044] The arrangement body fixing structure 60 is used to fix the solar panel unit 70 via the sheet waterproofing structure 1 onto the floor portion 11 of the body 10 on which the sheet waterproofing structure 1 is provided, and in this embodiment has a fixing bracket 50, a waterproof sheet piece 35, a spacer 45, and a metal sheet piece 34.

[0045] By using this arrangement member fixing structure 60, the solar panel unit 70 can be stably fixed to the floor portion 11 via this structure. Below, each part of this arrangement member fixing structure 60 will be explained in order.

[0046] Fixing metal fittings 50 (fixing anchors) are fixed to the tip of each leg 72, and by fixing the fixing metal fittings 50 to the floor portion 11 on which the insulating layer 40 is laid, the legs 72 are fixed to the floor portion 11 on which the insulating layer 40 is laid via the fixing metal fittings 50. In other words, the solar panel unit 70 is fixed to the floor portion 11 on which the insulating layer 40 is laid.

[0047] As shown in Figures 3 and 4, this fixing bracket 50 has a fixing plate 61 (metal piece), a bolt 62 (second fixing bolt), a bolt 63 (first fixing bolt), an anchor member 64 (columnar body), gaskets 36, 37, a seat plate 51, a fixing device main body 52, a washer 53, nuts 54, 55, a fixing body 56, a washer 57, and a nut 58.

[0048] The anchor member 64 (columnar body) has an overall cylindrical shape and has a female thread formed on its inner surface, and is fixed to the floor portion 11 by being driven into a hole 111 formed in the floor portion 11 (flat surface) to which the fixing bracket 50 is to be fixed.

[0049] 5, in this embodiment, the fixing plate 61 (metal piece) is made of a metal piece having an overall disk shape, i.e., a circular shape in a plan view, and includes one insertion hole 611 provided in its center (more specifically, the center), and also includes eight insertion holes 612 provided at intervals on a circumference having a smaller diameter than the fixing plate 61 and having the same center as the center of the fixing plate 61, on the edge side of the center. When placed on the waterproof sheet 30, the bolt 63 (first fixing bolt) is inserted into the insertion hole 611 so as to protrude toward the leg 72 side (upper side), and further, the bolt 62 (second fixing bolt) is inserted into the insertion hole 612 so as to protrude toward the floor 11 side (lower side) (see FIG. 3).

[0050] The bolt 62 (second fixing bolt) has a disk-shaped flange portion and a bolt body that protrudes from the center of the flange portion and has a male thread formed on its outer circumferential surface. The bolt body of this bolt 62 is inserted into the insertion hole 612 of the fixing plate 61 so as to protrude toward the floor portion 11 side (lower side), and then penetrates the waterproof sheet 30 and the heat insulating layer 40 and is screwed into the anchor member 64, whereby the bolt 62 is fixed by being driven into the floor portion 11, and as a result, the fixing plate 61 is fixed in a state of contact with the waterproof sheet 30 laid on the floor portion 11 via the heat insulating layer 40.

[0051] The bolt 62 is fixed to the floor 11 in a state where it is inserted through the insertion hole 612 (through hole), and at this time, a spacer 45 described later is arranged at a position corresponding to the lower side of the center of the fixed plate 61, but the shape of the fixed plate 61 in plan view is set to be larger than the spacer 45, and the insertion hole 612 is provided on the edge side of the fixed plate 61. Therefore, the bolt 62 can be fixed to the floor 11 by inserting the waterproof sheet 30 and the heat insulating layer 40 while avoiding the spacer 45. In other words, the bolt 63 inserted into the fixed plate 61 can be fixed to the floor 11 by the bolt 62 inserted into the fixed plate 61 while avoiding the spacer 45 and the metal sheet piece 34 covering the spacer 45 located below the fixed plate 61.

[0052] As mentioned above, the anchor member 64 (columnar body) is fixed to the floor portion 11 by being driven into a hole 111 formed in the floor portion 11, and further, the bolt 62 is inserted into the insertion hole 612 provided in the fixing plate 61 and screwed into the anchor member 64, so that the fixing plate 61 is fixed in contact with the waterproof sheet 30 laid on the floor portion 11 via the insulating layer 40.

[0053] The floor 11 into which the anchor members 64 are driven may take various forms, such as a flat plate such as an autoclaved lightweight aerated concrete (ALC) panel or an extruded cement board (ECP), or the floor 11 itself may be made of reinforced concrete. Therefore, depending on the form of the floor 11, the anchor members 64 and bolts 62 used to fix the fixing plate 61 are selected so that their bore and diameter are set to be small enough to prevent cracks, chips, etc. from occurring in the floor 11.

[0054] In contrast, in this embodiment, the fixed plate 61 into which the bolt 62 is inserted has a total of eight insertion holes 612 (through holes), with the first insertion holes 612a having a first diameter and the second insertion holes 612b having a second diameter smaller than the first diameter being provided alternately at equal intervals, with the same number of four first insertion holes 612a and four second insertion holes 612b being provided alternately on a circumference having the same center as the center of the fixed plate 61 (see FIG. 5). Thus, in the present invention, the fixed plate 61 has the first insertion holes 612a and the second insertion holes 612b having different diameters as the insertion holes 612.

[0055] Therefore, by using the insertion hole 612 having a diameter suitable for the anchor member 64 and the bolt 62 selected according to the form of the floor portion 11 out of the first insertion hole 612a and the second insertion hole 612b, the fixing plate 61 can be stably fixed to the floor portion 11 by the anchor member 64 and the bolt 62 while appropriately suppressing or preventing the occurrence of cracks, chips, etc. in the floor portion 11. That is, even if anchor members 64 and bolts 62 with different diameters and sizes are selected according to the form of the floor portion 11, the fixing plate 61 can be fixed to the floor portion 11 without changing the fixing plate 61 accordingly. Therefore, the fixing plate 61 can be used as a fixing plate (metal piece) with excellent versatility.

[0056] As mentioned above, each insertion hole 612 is provided at equal intervals on a circumference having the same center as the center of the fixed plate 61. The diameter of this circumference is not particularly limited as long as it is smaller than the diameter of the fixed plate 61, but is preferably set to, for example, 50.0 mm or more and 300.0 mm or less, more preferably 70.0 mm or more and 250.0 mm or less, and more preferably 80.0 mm or more and 180.0 mm or less.

[0057] In addition, the first size, which is the aperture of the first insertion hole 612a, is preferably set to be greater than or equal to 5.0 mm and less than or equal to 15.0 mm, more preferably greater than or equal to 8.0 mm and less than or equal to 13.0 mm, and the second size, which is the aperture of the second insertion hole 612b, only needs to be smaller than the first size, but is preferably set to be greater than or equal to 2.0 mm and less than or equal to 12.0 mm, more preferably greater than or equal to 4.0 mm and less than or equal to 9.0 mm.

[0058] By setting the size of the circumference, the size of the aperture of the first insertion hole 612a, and the size of the aperture of the second insertion hole 612b within the above ranges, excellent strength is imparted to the fixing plate 61, and the fixing plate 61 can be more stably fixed to the floor portion 11 by the anchor member 64 and the bolt 62. Furthermore, by setting the size of the aperture of the first insertion hole 612a and the size of the aperture of the second insertion hole 612b within the above ranges, the bolt 62 selected according to the shape of the floor portion 11 can be inserted into either the first insertion hole 612a or the second insertion hole 612b with the size of the aperture matching.

[0059] Furthermore, the first through hole 612a and the second through hole 612b each have a tapered portion at the upper end (waterproof sheet piece 35) side where the diameter (inner diameter) gradually increases from bottom to top (see FIG. 4), and it is preferable that the taper angle of the first through hole 612a is larger than the taper angle of the second through hole 612b. This allows the fixing plate 61 to be fixed to the floor 11 with higher strength by the bolts 62 inserted into the first through hole 612a and the second through hole 612b, respectively.

[0060] Moreover, the fixing plate 61 is preferably a metal plate whose surface is coated with resin (a resin-coated metal plate), which provides the fixing plate 61 with excellent strength while appropriately suppressing or preventing undesired corrosion of the metal plate.

[0061] The metal plate is not particularly limited, but examples thereof include steel plates such as stainless steel plates and iron plates, aluminum plates, and copper plates, with steel plates being preferred, as this provides the fixing plate 61 with excellent strength.

[0062] Examples of resins that cover the surface of the metal plate include vinyl chloride resins such as polyvinyl chloride, polyolefin resins, ethylene-vinyl acetate copolymers, etc., and one or more of these resins may be used in combination, with polyvinyl chloride being preferred. Polyvinyl chloride has excellent solvent weldability and heat fusion properties, and therefore can more reliably prevent corrosion of the metal plate.

[0063] Moreover, the bolt 63 (first fixing bolt) has a disk-shaped flange portion and a bolt body that protrudes from the center of the flange portion and has a male thread formed on its outer circumferential surface. The bolt body of this bolt 63 is inserted into the insertion hole 611 of the fixing plate 61 so as to protrude towards the leg 72 side (upper side), and the fixing plate 61 is fixed onto the waterproof sheet 30, so that the bolt 63 is fixed onto the waterproof sheet 30 via the fixing plate 61 in a state where it protrudes towards the leg 72 side.

[0064] When the bolt 63 is inserted into the insertion hole 611, it protrudes towards the leg 72. At this time, the bolt 63 may or may not be fixed to the fixing plate 61 (insertion hole 611), but it is preferable that the bolt 63 is fixed by adhesive, welding, or the like. This makes it possible to appropriately suppress or prevent the infiltration of water such as rainwater into the insulating layer 40 side through the insertion hole 611. Therefore, the fixing metal fitting 50, and therefore the arranging body fixing structure 60, can be installed in the sheet waterproof structure 1 with better liquid-tightness.

[0065] Fixing device main body 52 has a rectangular flat plate shape in a plan view, a bottom portion with a through hole penetrating in the thickness direction at its center, and a rising portion erected from an edge portion of one side of the bottom portion. Packings 36, 37 and seat plate 51, which are formed in substantially the same shape as fixing plate 61 and have a through hole at their center, are arranged below the bottom portion of fixing device main body 52. ​​Bolts 63 are inserted into the through holes of each component, and nuts 54, 55 are screwed together with washers 53 interposed therebetween, whereby fixing device main body 52 is fixed to floor 11 via bolts 63, fixing plate 61, bolts 62, and anchor members 64.

[0066] Fixing body 56 has a pair of bottoms each having a rectangular flat plate shape in plan view, a pair of rising parts standing from the edge of one side of each bottom, and a top part that connects the tips of these rising parts and has a through hole penetrating through the thickness direction at its center. Fixing body 56 is fixed to fixing device main body 52 by bringing the bottom part of fixing device 56 into contact with the bottom part of fixing device main body 52, inserting bolt 63 into the through hole of fixing device 56 (top part), and screwing nut 58 with washer 57 interposed therebetween, thereby making the fixing strength of fixing device main body 52 to fixing plate 61 via bolt 63 stronger.

[0067] By configuring the fixing bracket 50 in this manner, the fixing bracket 50 is firmly fixed to the floor 11 on which the insulation layer 40 and the waterproof sheet 30 are laid in this order from the floor 11 side. Therefore, as shown in Fig. 3, a bolt 74 is inserted into a through hole formed in the rising portion of the fixing device main body 52, and then this bolt 74 is inserted into a through hole provided in the leg 72, and then a nut 73 is screwed in, whereby the leg 72 is fixed via the fixing bracket 50 to the floor 11 on which the insulation layer 40 and the waterproof sheet 30 are laid. In other words, the solar panel unit 70 is fixed via the fixing bracket 50 to the floor 11 on which the insulation layer 40 and the waterproof sheet 30 are laid.

[0068] The waterproof sheet piece 35 has a flat plate shape larger than the fixed plate 61 in a plan view, and has a through hole in the center that penetrates in the thickness direction.The waterproof sheet piece 35 is fixed to the waterproof sheet 30 and further to the fixed plate 61 with the bolt body of the bolt 63 protruding toward the leg 72 inserted into this through hole, thereby ensuring waterproofing of the components of the fixing bracket 50 that are located below the waterproof sheet piece 35, i.e., the fixed plate 61, the bolts 62, 63 and the anchor member 64.

[0069] The waterproof sheet piece 35 may be made of the same materials as those listed for the waterproof sheet 30.

[0070] The spacer 45 has a cylindrical overall shape, penetrates the heat insulating layer 40 in the thickness direction, and is disposed in a through hole 41 provided on the lower side thereof in correspondence with the fixing metal fitting 50 .

[0071] As shown in Figure 3, the height of this spacer 45 is set approximately equal to the combined thickness of the insulation layer 40 and the waterproof sheet 30, and it has a cylindrical body 46 that is harder than the insulation layer 40, and an insulation piece 47 filled in the internal space of this cylindrical body 46.

[0072] The spacer 45 having such a configuration is disposed on the floor 11 by being inserted into the through-hole 41 formed in the heat insulating layer 40 on the underside thereof in correspondence with the fixing metal fitting 50, and into the hole 301 provided in the thickness direction of the waterproof sheet 30. Therefore, the fixing plate 61 provided in the fixing metal fitting 50 is supported by the floor 11 via the spacer 45. At this time, since the spacer 45 has a cylindrical body 46 having a higher hardness than the heat insulating layer 40, it can support the fixing plate 61 and therefore the fixing metal fitting 50 with excellent strength. Therefore, it is possible to appropriately suppress or prevent the spacer 45 from being crushed by the weight of the solar panel unit 70 as an arrangement body fixed to the floor 11 via the fixing metal fitting 50, and therefore the solar panel unit 70 can be fixed to the floor 11 without causing the positional deviation of the solar panel unit 70 from the floor 11 for a long period of time.

[0073] 3, the height of the spacer 45 is preferably set to be approximately equal to the combined thickness of the insulating layer 40 and the waterproof sheet 30, but may be set to be approximately equal to the thickness of the insulating layer 40. Even when the height of the spacer 45 is set to be approximately equal to the thickness of the insulating layer 40, the above-mentioned effect obtained by arranging the spacer 45 in correspondence with the fixing metal fittings 50 can be exerted in approximately the same manner.

[0074] In addition, in this specification, the height of the spacer 45 being approximately equal to the total thickness of the insulating layer 40 and the waterproof sheet 30, or the thickness of the insulating layer 40, means that an error in the height of the spacer 45 of within ±10.0% is permitted relative to the total thickness of the insulating layer 40 and the waterproof sheet 30, or the thickness of the insulating layer 40, respectively.

[0075] The cylindrical body 46 is made of a dense material that can have a higher hardness than the insulating layer 40. Examples of this material include resin materials such as polyvinyl chloride resin, polyester resin, polyimide resin, polyamide resin, polycarbonate resin, and acrylic resin, and metal materials such as titanium, aluminum, nickel, and stainless steel. One or a combination of two or more of these materials can be used.

[0076] The insulating piece 47 is preferably made of a foam. This allows the insulating piece 47 to have the same function as the insulating layer 40. Therefore, at the position where the spacer 45 is arranged, it is possible to appropriately suppress or prevent heat from being transmitted from the outside to the inside of the body 10.

[0077] The insulating pieces 47 may be made of the same materials as those used for the insulating layer 40 .

[0078] The metal sheet piece 34 has a rectangular shape when viewed from above, and covers the waterproof sheet 30 at a position corresponding to the fixing metal fitting 50.

[0079] The waterproof sheet 30 is provided to place the spacer 45 in the through hole 41 of the thermal insulation layer 40, and has a hole 301 penetrating through the thickness direction, formed to correspond to the through hole 41 (spacer 45) at a position overlapping in a plan view. The metal sheet piece 34 covers the hole 301 formed in the waterproof sheet 30, and the shape of the metal sheet piece 34 in a plan view is set to be larger than the spacer 45, i.e., the hole 301. As a result, the metal sheet piece 34 can cover the waterproof sheet 30 at a position corresponding to the fixing metal fitting 50, encompassing the hole 301 and the spacer 45 in a plan view of the waterproof sheet 30.

[0080] In this way, even if the hole 301 is formed in the waterproof sheet 30 for the arrangement of the spacer 45 corresponding to the through hole 41, the metal sheet piece 34 covers the waterproof sheet 30, encompassing the hole 301. The waterproof sheet piece 35 covers the waterproof sheet 30, encompassing the metal sheet piece 34. Therefore, the metal sheet piece 34 and the waterproof sheet piece 35 can adequately suppress or prevent water such as rainwater from penetrating into the structure 10 through the hole 301. Therefore, it is possible to adequately suppress or prevent the deterioration of the waterproofing caused by the sheet waterproofing structure 1 applied to the structure 10. In addition, the construction of the sheet waterproofing structure 1 and the arrangement body fixing structure 60 on the floor part 11 of the structure 10 is carried out by forming the sheet waterproofing structure 1 on the floor part 11 and then providing the arrangement body fixing structure 60. Therefore, after the metal sheet piece 34 covers the waterproof sheet 30 including the hole 301, the waterproof sheet 30 including the metal sheet piece 34 is covered with the waterproof sheet piece 35. Therefore, even if the sheet waterproof structure 1 is exposed to wind and rain during construction of the sheet waterproofing structure 1 and the arrangement body fixing structure 60, for example, after the waterproof sheet 30 is covered with the metal sheet piece 34, until the waterproof sheet 30 is covered with the waterproof sheet piece 35, the metal sheet piece 34 can adequately suppress or prevent rainwater from penetrating into the floor part 11 through the hole 301. Furthermore, the plasticizer contained in the waterproof sheet piece 35 can be reliably prevented from migrating to the insulating piece 47 side due to unintended contact between the waterproof sheet piece 35 and the insulating piece 47, so that the deterioration and degradation of the waterproof sheet piece 35 can be more adequately suppressed or prevented. With the spacer 45 positioned in correspondence with the through hole 41, the fixing bracket 50 and thus the mounting body fixing structure 60 can be fixed to the floor portion 11, and therefore the solar panel unit 70 fixed to the floor portion 11 via this mounting body fixing structure 60 can be fixed with excellent strength.

[0081] The metal sheet pieces 34 are mainly made of a metal material, and the metal material is not particularly limited, but may be, for example, aluminum, nickel, stainless steel, copper, titanium, tungsten, etc., and these metals may be used alone or as an alloy. Among these, aluminum is preferable. That is, the metal sheet pieces 34 are preferably aluminum sheet pieces. This allows the waterproof sheet 30 to be covered with excellent adhesion, including the holes 301 and the spacers 45.

[0082] In this embodiment, as shown in FIG. 7, the metal sheet piece 34 has a rectangular shape in a plan view, and has four markers 341 provided on the inside of the center of each of the four sides that make up its edge.

[0083] Here, the fixing position for fixing the fixing bracket 50 is generally determined by the intersection of a marked line 332 marked in the left-right direction and a marked line 331 marked in the front-rear direction perpendicular to the left-right direction. However, in the present invention, when attaching the metal sheet piece 34 to the waterproof sheet 30 and fixing the fixing bracket 50 to the floor section 11, a spacer 45 is placed in the hole 301 and the through hole 41 formed at a position corresponding to the intersection of the marked lines 331, 332, and the intersection of the marked lines 331, 332 disappears from above the waterproof sheet 30. In contrast, in the present embodiment, as described above, the metal sheet piece 34 has four markers 341, of which two markers 341 provided corresponding to each of the two sides extending in the front-to-rear direction are positioned so as to overlap the marking line 332, and further, two markers 341 provided corresponding to each of the two sides extending in the left-to-right direction are positioned so as to overlap the marking line 331, thereby enabling the metal sheet piece 34 to be affixed to the spacer 45 with high positional accuracy.

[0084] In this embodiment, the fixed plate 61 has four first insertion holes 612a and four second insertion holes 612b with different diameters arranged alternately on the same circumference, that is, the fixed plate 61 has two insertion holes 612 with different diameters. However, this is not limited to this case, and for example, the fixed plate 61 may have three or more insertion holes 612 with different diameters.

[0085] Further, the first through holes 612a and the second through holes 612b alternately provided on the same circumference may be provided in the fixing plate 61 by two or more, but it is preferable to provide four or five of them as in this embodiment. Here, the fixing plate 61 is fixed to the floor 11 by using the bolts 62 and the anchor members 64 as described above, and in this fixing, from the viewpoint of fixing the fixing plate 61 to the floor 11 more firmly, it is preferable to fix the fixing plate 61 in a state in which the bolts 62 are inserted into the three through holes 612. Therefore, it is preferable that the fixing plate 61 has four or five first through holes 612a and second through holes 612b as the through holes 612, because one or two failures are allowed when forming the hole portions 111 for driving the anchor members 64 in the floor 11.

[0086] Furthermore, the first insertion holes 612a and the second insertion holes 612b are alternately provided on the same circumference, but as shown in FIG. 6, the second insertion holes 612b may be provided on a circumference (second circumference) having a diameter smaller than the diameter of the circumference (first circumference) on which the first insertion holes 612a are provided.

[0087] In addition, although the fixing plate 61 has a circular shape when viewed in a planar view, the shape is not limited to this and may be a polygonal shape such as a square or pentagon, and may have insertion holes 612 including a first insertion hole 612a and a second insertion hole 612b near the edges including each corner.

[0088] In addition, in this embodiment, the fixing bracket 50 has been described as having a fixing plate 61, bolts 62, 63, anchor member 64, gaskets 36, 37, seat plate 51, fixing device main body 52, washer 53, nuts 54, 55, fixing body 56, washer 57, and nut 58, but is not limited to this configuration and may have any configuration as long as it has a fixing plate 61, bolts 62, 63, and the solar panel unit 70 is fixed to the fixing bracket 50 via the bolt 63.

[0089] Further, the spacer 45 has been described as having a cylindrical overall shape, but is not limited to this and may have any shape as long as it is a columnar body, for example, a polygonal column shape such as a triangular column or a quadrangular column.

[0090] Although the arrangement fixing structure and fixing metal fittings of the present invention have been described above, the present invention is not limited to these.

[0091] For example, in the arrangement fixing structure and fixing metal fitting of the present invention, each component can be replaced with any component that can exert a similar function, or any component can be added.

[0092] In the above embodiment, the sheet waterproofing structure has been described as having a heat insulating layer, a waterproof sheet, a placement member, and a fixed disk, but at least one of the heat insulating layer, the placement member, and the fixed disk, except for the waterproof sheet, may be omitted. When the heat insulating layer, the placement member, and the fixed disk are omitted in the sheet waterproofing structure, the waterproof sheet is joined to the floor portion via an adhesive or the like. When the heat insulating layer is omitted, the placement body fixing structure is configured to have a fixing metal fitting and a waterproof sheet piece, with the spacer and the metal sheet piece omitted.

[0093] Furthermore, in the above embodiment, a case has been described in which a metal sheet piece is selected as a member for covering the hole formed in the waterproof sheet for the placement of the spacer, but this member is not limited to this as long as it is capable of suppressing or preventing the infiltration of water such as rainwater into the main body, and may be, for example, a resin sheet piece composed primarily of a resin material such as polyolefin resin, polyester resin, or polyamide resin.

[0094] In addition, in the above embodiment, a case has been described in which the arrangement fixed to the main body by the arrangement fixing structure and fixing hardware of the present invention is a solar panel unit, but this is not limited to this case, and the arrangement may also be an outdoor unit, a substation, an antenna, a carport, etc., provided in an air conditioning system.

[0095] Furthermore, the structure is not limited to one having a floor and walls, and may be one in which the walls are omitted. [Explanation of symbols]
