Description

[Technical Field]

[0001] The present invention relates to an attachment plate and a platform foundation, and more particularly to an attachment plate and a platform foundation including the attachment plate. [Background technology]

[0002] Roofs on which photovoltaic power generation facilities equipped with multiple solar cell modules are installed are known (see, for example, Patent Document 1). Such roofs are deck-based roofs in which heat insulating material is provided on the upper surface of a deck plate used as the roof base, and this heat insulating material is further covered with a waterproof sheet.

[0003] Such a roof mounting structure (mounting foundation for equipment installation) is a structure for attaching the frame of a mounting for equipment such as solar power generation equipment or devices, and is equipped with a support, a raising base, a waterproof covering material, fixing rails, sealing tape, and gripping tools.

[0004] The receiver is configured as, for example, a metal fitting having a head and multiple legs extending downward from the head, and these multiple legs pierce the insulation from its top surface and are positioned on the top surface of the wave crests (peaks) of the deck plate, which is the roof substrate. The elevation platform is placed on the receiver from above the insulation, and is fixed to the deck plate, which is the roof substrate, with screws (fastening members) that penetrate the receiver from the top.

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2011-208361 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the raising platform in Patent Document 1 is simply attached to the top of the deck plate via screws that penetrate perpendicularly to the deck plate, together with the support fixture with its legs resting on the top. In this case, the pull-out force on the equipment installation base becomes an issue, and a base base with higher bearing strength is desired.

[0007] Therefore, the present invention has been made in consideration of the above-mentioned problems, and aims to provide a technology that enables a mounting base to be attached to a deck plate with higher bearing strength. [Means for solving the problem]

[0008] In order to solve the above problems, the present invention provides an attachment plate used to attach a mounting base to a corrugated deck plate used as a roof underlayment, which is formed by a series of multiple consecutive peaks and valleys connected together via inclined sections that are alternately inclined in different directions, and is characterized by comprising a pair of fixing sections that face each of the inclined sections inclined in different directions and are fixed to the inclined sections via fastening members, and a mounting section that extends between the pair of fixing sections, covers at least one of the peaks, and to which the mounting base is attached.

[0009] In the attachment plate according to one aspect of the present invention, the mounting portion may be fixed to the peak portion via a fastening member.

[0010] In an attachment plate according to one aspect of the present invention, the fixing portion may have an engaging portion on the side opposite the mounting portion that engages with a groove formed at the transition between the inclined portion and the valley bottom portion.

[0011] In the attachment plate according to one aspect of the present invention, the angle formed between the fixing portion and the mounting portion may be an acute angle or a substantially right angle.

[0012] In the attachment plate according to one aspect of the present invention, the fixing portions may be fixed to adjacent ones of the inclined portions.

[0013] In the attachment plate according to one aspect of the present invention, the fixing portion may be fixed to one of the inclined portions other than the adjacent inclined portions.

[0014] Furthermore, in order to solve the above-mentioned problems, the present invention provides a mounting foundation for installing equipment on a corrugated deck plate used as a roof underlayment, which is formed by a series of multiple peaks and valleys that are continuous with each other via inclined sections that are alternately inclined in different directions, and is characterized by comprising: an attachment plate having a pair of fixing sections that face each of the inclined sections inclined in different directions and are fixed to the inclined sections via fastening members, and a mounting section that extends between the pair of fixing sections and covers at least one of the peaks; and a mounting base that is installed on the attachment plate and to which the equipment is attached.

[0017] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that in the following description, the drawings are schematic, and the dimensional relationships and ratios of elements may differ from the actual ones. The dimensional relationships and ratios may differ between the drawings.

[0018] 1 is a perspective view showing a roof foundation 100 that employs a rack foundation 1 according to the present invention. The rack foundation 1 according to the present invention is attached to a deck plate used in the roof foundation 100, and is a structure for installing equipment 200, such as a solar power generation system, a hot water unit for heating water, an outdoor unit for an air conditioner, or other equipment including signs, on the roof of a building.

[0019] <Roofing underlayment> The roof underlayment 100 comprises a deck plate 120, roof insulation 140, a roof waterproof sheet 160, and the frame foundation 1 according to the present invention. In the following, the direction in which the deck plate 120 is laid across beams B will be referred to as the longitudinal direction (length direction) L of the deck plate 120, and the direction in which the deck plate 120 extends, intersecting the longitudinal direction L, will be referred to as the transverse direction (width direction) W.

[0020] A fixed rail 210 is fixed to the frame foundation 1 via equipment screws 34, which will be described later. The fixed rail 210 is a steel material with a U-shaped cross section. The fixed rail 210 is provided along the longitudinal direction L with respect to one of the multiple peaks 121 of a deck plate 120, which will be described later. A support 220 extending from the equipment 200 is fixed to the fixed rail 210. In this way, the equipment 200 is installed on the roof underlayment 100. Note that the fixed rail 210 can also be provided along the short direction W, and the equipment 200 may also be installed directly on the roof underlayment 100 without the fixed rail 210.

[0021] [Deck plate] The rack foundation 1 according to the present invention can be attached to, for example, a deck plate 120 described below, but the deck plate to which the rack foundation 1 is attached is not particularly limited. FIG. 2 is an enlarged cross-sectional view showing the rack foundation 1 portion of the roof underlayment 100 shown in FIG. 1 . The deck plate 120 is a corrugated steel plate formed by roll forming or the like from a surface-treated thin steel plate. The deck plate 120 has a peak portion 121, a valley bottom portion 122, and an inclined portion 123. Note that the deck plate 120 does not necessarily have to be surface-treated.

[0022] The deck plate 120 has a wave shape in which peaks 121 and valleys 122 each extending in the longitudinal direction L are continuous with each other in the lateral direction W via an inclined portion 123 also extending in the longitudinal direction L.

[0023] Each deck plate 120 is made up of two peaks 121, one valley bottom 122, and two pairs of inclined portions 123, and is formed in a wave shape in cross section along the short direction W. Note that, depending on the dimension of the deck plate 120 in the short direction W, only one peak 121 may be provided on one deck plate 120. Furthermore, when one deck plate 120 is connected to another deck plate 120 in the short direction W, the connection portion between the deck plates 120 functions as a valley bottom 122. The deck plate 120 may be end-closed at both ends in the longitudinal direction L.

[0024] The peak portion 121 is a flat portion located above and spaced apart from the beam B when the beam B is bridged between the beams B, and is a plate-like portion extending in the longitudinal direction L. The peak portion 121 has a groove 1210. The groove 1210 is formed so as to be recessed toward the valley bottom portion 122. The groove 1210 extends in the longitudinal direction L, and when there is only one groove 1210, it is provided near the center in the lateral direction W.

[0025] The groove 1210 in the peak portion 121 improves the strength of the peak portion 121. There is no need to form a single groove 1210 in the peak portion 121, and a plurality of grooves 1210 may be formed. Note that the groove 1210 does not necessarily have to be formed.

[0026] The valley bottom 122 is parallel or approximately parallel to the peak 121, and is a flat portion that is placed on the beam B when the beam B is bridged between the beams B. The valley bottom 122 is a plate-like portion that extends in the longitudinal direction L. The valley bottom 122 does not overlap with the peak 121 in the lateral direction W. Note that the groove 1210 formed in the peak 121 may also be formed in the valley bottom 122.

[0027] The inclined portions 123 are portions that connect the peaks 121 and the valley bottoms 122, and are plate-shaped portions that extend in the longitudinal direction L. The inclined portions 123 extend obliquely from both end sides of the peaks 121 toward the valley bottoms 122 in the short direction W. The inclined portions 123 that are adjacent to each other in the short direction W extend in different directions from the peaks 121 so as to be spaced apart from each other. The inclined portions 123 are inclined so as to form a predetermined angle, for example, an obtuse angle, with respect to the peaks 121 and the valley bottoms 122. Note that the grooves 1210 formed in the peaks 121 may be formed in the inclined portions 123.

[0028] A plurality of embossed portions 1230 are formed on the inclined portion 123. The embossed portions 1230 are provided at predetermined intervals along the longitudinal direction L. The embossed portions 1230 are formed so as to protrude from the inside to the outside of the deck plate 120. The embossed portions 1230 increase the rigidity of the deck plate 120. The intervals between the embossed portions 1230 can be set as desired; for example, the embossed portions 1230 may extend without any intervals along the longitudinal direction L.

[0029] A bulge 124 is formed at the transition between the valley bottom 122 and the inclined portion 123. The bulge 124 is a portion that protrudes to opposite sides of a pair of inclined portions 123 in one peak portion 121. That is, in a pair of inclined portions 123 that face each other across the valley bottom 122, the bulge 124 is formed to face each other and bulges in directions that bring them closer to each other.

[0030] An engagement groove (dovetail groove) 125 extending along the longitudinal direction L is formed between the bulge portion 124 and the valley bottom 122. The cross section of the engagement groove 125 along the short direction W is formed to be curved. The engagement groove 125 is formed in a pair of inclined portions 123 in one crest portion 121 in directions approaching each other. That is, in a pair of inclined portions 123 facing each other across the valley bottom 122 of the deck plate 120, the engagement grooves 125 are formed to face each other and curve in directions away from each other. Note that the engagement groove 125 may be formed with protrusions in the short direction W toward the valley bottom 122 at predetermined intervals along the longitudinal direction L by embossing.

[0031] [Roof insulation, roof waterproofing sheets] The roof insulation 140 is a plate-like member made of a lightweight material containing air (such as a foam material), such as phenolic foam. The roof insulation 140 is laid over the entire roof underlayment 100 on the deck plate 120, except for the area of ​​the frame foundation 1. The roof waterproofing sheet 160 is a synthetic resin sheet, asphalt sheet, or the like, and although its material and thickness are not limited, it has a certain environmental adaptability (i.e., the property of being resistant to deterioration when exposed to sunlight or raindrops). The roof waterproofing sheet 160 is laid over the laid roof insulation 140. In addition, sheathing boards (not shown), which are plate-like members made of, for example, cemented wood wool boards, may be provided above, below, or above and below the roof insulation 140.

[0032] [Frame foundation] The rack foundation 1 according to the present invention is for installing equipment on a corrugated deck plate 120 used for a roof underlayment 100 formed of a plurality of continuous peaks 121 and valley bottoms 122 connected to one another via inclined sections 123 that are alternately inclined in different directions, and is characterized by comprising an attachment plate 10 having a pair of fixing legs (fixing sections) 13 facing the inclined sections 123 inclined in different directions and fixed to the inclined sections 123 via fastening members DB2, and a mounting section 11 extending between the pair of fixing sections 13 and covering at least one of the peaks 121, and a rack 30 that is installed on the attachment plate 10 and to which equipment is attached. The rack foundation 1 according to the present invention will be specifically described below.

[0033] Fig. 3A is a perspective view showing the state in which the rack foundation 1 according to the present invention is attached to the deck plate 120. Fig. 3B is a front view showing the state in which the rack foundation 1 according to the present invention is attached to the deck plate 120. The rack foundation 1 is attached to the deck plate 120, and is used to attach equipment 200 via fixed rails 210 or supports 220. The rack foundation 1 includes an attachment plate 10 and a rack 30. Note that the equipment 200 may also be attached directly to the deck plate 120 by the rack foundation 1.

[0034] (Attachment plate) The attachment plate 10 is a plate-like member made of, for example, steel, resin, or the like, and is attached to the deck plate 120 so as to straddle one peak portion 121 of the deck plate 120. The attachment plate 10 is formed in a U-shape or an approximately U-shape when viewed from the front. The attachment plate 10 is provided on one peak portion 121 of the deck plate 120 at a position where a fixed rail 210 to which a support column 220 of the equipment 200 is fixed is disposed along the longitudinal direction L or the lateral direction W, or at a position where the support column 220 is disposed.

[0035] FIG. 4 is an exploded perspective view showing a rack foundation 1 according to the present invention. The attachment plate 10 in this embodiment is a plate-like member used to attach a rack 30 for installing equipment 200 to a corrugated deck plate 120 used for a roof underlayment 100, which is formed by connecting multiple continuous peaks 121 and valley bottoms 122 via inclined portions 123 that are alternately inclined in different directions. The attachment plate 10 is characterized by including a pair of fixing legs (fixing portions) 13 that face the inclined portions 123 of the deck plate 120, respectively, inclined in different directions, and are fixed to the inclined portions 123 via fastening members DB2, and a mounting portion 11 that extends between the pair of fixing legs 13, covers at least one peak 121, and to which the rack 30 is attached. The attachment plate 10 in this embodiment will be specifically described below.

[0036] The attachment plate 10 has a mounting portion 11 and a pair of fixing legs (fixing portions) 13. The mounting portion 11 is placed on the summit portion 121 when the attachment plate 10 is attached to the deck plate 120 (hereinafter simply referred to as the "attached state").

[0037] In the attached state, the attachment portion 11 is formed flat along the peak portion 121. The dimension of the attachment portion 11 in the short-side direction W is the same as or approximately the same as the dimension of the peak portion 121 in the short-side direction W. The attachment portion 11 has a recess 12 formed in a concave shape on the side from which the fixing leg portion 13 extends. In the attached state, the recess 12 extends along the longitudinal direction L and protrudes into a groove 1210 formed in the peak portion 121. The recess 12 increases the rigidity of the attachment plate 10, and fitting the recess 12 into the groove 1210 enables stable positioning of the attachment plate 10 in the short-side direction W relative to the deck plate 120. The recess 12 does not have to be formed.

[0038] In the attached state, the attachment plate 10 is attached to the deck plate 120 at the attachment portion 11 with a plurality of fastening members DB1, such as drilling tapping screws. A rack 30, which will be described later, is detachably attached to the attachment portion 11 with fastening members DB3, such as drilling tapping screws. Note that the attachment plate 10 does not have to be attached to the deck plate 120 at the attachment portion 11.

[0039] In the mounted state, the pair of fixing legs 13 are provided on either side of the mounting portion 11 extending along the longitudinal direction L, and extend along the inclined portion 123. In other words, the fixing legs 13 extend away from each other from the mounting portion 11. The pair of fixing legs 13 may be elastically deformable so as to move toward and away from each other. The fixing legs 13 form, for example, an obtuse angle with respect to the mounting portion 11. In the mounted state, the tip of the fixing leg 13 reaches the portion of the bulging portion 124 of the deck plate 120 that faces the mounting portion 11.

[0040] The fixing legs 13 are shaped to conform to the inclined portions 123 and are in surface contact with the inclined portions 123 in the attached state. Each fixing leg 13 is provided with an engaging protrusion 130. The engaging protrusion 130 is formed so as to protrude from the inside to the outside of the attachment plate 10. The engaging protrusion 130 extends along the longitudinal direction L and engages with the embossed portion 1230 of the deck plate 120 in the attached state. The engagement between the attachment plate 10 and the deck plate 120 increases the strength against external forces that attempt to remove the attachment plate 10 from the deck plate 120. Furthermore, during installation, slippage in a temporary placement state can be suppressed, improving installation efficiency. Note that, depending on the surface shape of the inclined portions 123, a gap may be formed between the inclined portions 123 and the fixing legs 13.

[0041] In the mounted state, the attachment plate 10 is attached to the inclined portion 123 of the deck plate 120 at the fixed legs 13 by a plurality of fastening members DB2, such as drilling tapping screws. The fastening members DB2 are driven into a plurality of locations on each fixed leg 13 along the longitudinal direction L (see FIG. 3A).

[0042] (mounting) The frame 30 is attached to an attachment plate 10 and connected to a deck plate 120 via the attachment plate 10. In the attached state, a support 220 or a fixed rail 210 of the equipment 200 is attached to the frame 30. The frame 30 has a main body 31 with a circular cross section and an inter-component insulating material 36.

[0043] The main body 31 has a cylindrical portion 32, a top surface portion 33, an installation screw 34, and a bottom surface portion 35. The cylindrical portion 32 is a cylindrical member formed, for example, from steel, resin, etc., with an elliptical or circular cross section, and one end is closed by a plate-like top surface portion 33 formed, for example, from steel, resin, etc. The outer diameter of the top surface portion 33 is the same as or approximately the same as the outer diameter of the cylindrical portion 32. The top surface portion 33 is integrally and concentrically connected to the cylindrical portion 32, for example, by welding, etc. The shape of the top surface portion 33 is not particularly limited, as long as it corresponds to the shape of the cylindrical portion 32.

[0044] An equipment screw 34 is attached to the center of the top surface portion 33, that is, on an axis passing through the center of the cylindrical portion 32. The equipment screw 34 is fixed to the top surface portion 33, for example, by welding. The equipment screw 34 is adapted to be screwed directly into the fixed rail 210 to which the support column 220 of the equipment 200 is fixed, or into the support column 220.

[0045] A bottom surface portion 35 made of, for example, steel or resin is attached by welding to the other end of the cylindrical portion 32 opposite the top surface portion 33. The bottom surface portion 35 is a plate member that is rectangular in plan view. When attached to the cylindrical portion 32, a portion of the bottom surface portion 35 extends outward from the outer circumferential surface of the cylindrical portion 32 to form a portion that functions as a flange. The shape of the bottom surface portion 35 is not limited and may be, for example, another polygonal shape, a circle, or the like.

[0046] The main body 31 is attached to the attachment plate 10 by driving fastening members DB3, such as drilling tapping screws, into the bottom surface 35, and is also attached to the crest 121 of the deck plate 120 via the attachment plate 10. In the attached state, the bottom surface 35 of the base 30 is on the side facing the attachment plate 10.

[0047] The inter-component insulation 36 is a plate-like member made of a material with insulating properties, such as ABS resin or phenol foam. In the installed state, the inter-component insulation 36 is provided between the bottom surface portion 35 and the attachment plate 10. The inter-component insulation 36 is formed, for example, in a rectangular shape in a plan view, and is formed with the same or approximately the same dimensions as the bottom surface portion 35. The inter-component insulation 36 is fixed to the main body 31 and the attachment plate 10 by fastening members DB3. The shape of the inter-component insulation 36 is not limited to a rectangular shape, as long as it corresponds to the shape of the tubular portion 32.

[0048] [Roof underlayment construction process] Next, a method for installing the rack foundation 1 according to this embodiment on the deck plate 120 will be described. FIG. 5A is a diagram showing a process for attaching the attachment plate 10 to the summit portion 121 of the deck plate 120.

[0049] First, the attachment plate 10 is installed at a position on the deck plate 120 where the equipment 200 will be placed, specifically, at a predetermined position on the summit 121 of the deck plate 120 where the fixed rail 210 or support 220 to which the equipment 200 is fixed will be placed. The attachment plate 10 is installed so that it fits into the summit 121 from the side of the fixed legs 13. Because the fixed legs 13 of the attachment plate 10 sandwich the summit 121, it is possible to prevent the attachment plate 10 from shifting from a desired position relative to the deck plate 120 in the longitudinal direction L and the lateral direction W. By aligning the recess 12 in the mounting portion 11 of the attachment plate 10 with the groove 1210 in the summit 121 of the deck plate 120, it is easy to position the attachment plate 10 relative to the deck plate 120.

[0050] Next, fastening members DB1 are driven into the mounting portions 11 of the attachment plate 10 installed on the peak portion 121, thereby fixing the attachment plate 10 to the peak portion 121 of the deck plate 120. The fastening members DB1 are driven into multiple locations along the longitudinal direction L, sandwiching the recess 12. Furthermore, multiple fastening members DB2 are driven into the inclined portions 123 of the deck plate 120 along the longitudinal direction L on each of the fixing legs 13, fixing the attachment plate 10 to the deck plate 120.

[0051] 5B is a diagram showing the process of attaching the mounting base 30 to the attachment plate 10. Next, the inter-component insulation 36 is placed on the attachment plate 10, and the main body 31 is placed on the inter-component insulation 36 from the bottom surface 35 side. Fastening members DB3 are driven into the bottom surface 35 of the main body 31 to fix the mounting base 30 to the attachment plate 10 and the deck plate 120.

[0052] 5C shows the process of installing roof insulation material 140 and other materials. Next, roof insulation material 140 is laid out so as to cover the parts of deck plate 120 other than mounting frame 30. Another insulation material 150 is filled in the gap between mounting frame 30 and roof insulation material 140. Next, roof waterproof sheet 160 is installed so as to cover roof insulation materials 140 and 150 (see FIG. 2). Finally, the entire structure, including mounting frame 30, is covered with a waterproof reinforcing sheet.

[0053] The roof underlayment 100 constructed in this manner employs the rack foundation 1 according to this embodiment, and therefore the fastening members DB3 driven into the fixed legs 13 of the attachment plate 10 can provide a shear strength (shear strength) τ against an external force p that acts on the attachment plate 10 in a direction along the sloped portion 123 of the deck plate 120 and tends to pull out the rack foundation 1. The shear strength τ is greater than the tensile strength (tensile strength) σ provided by the fastening members DB1 driven into the crest portion 121 of the deck plate 120 through the mounting portions 11 (see FIG. 3B).

[0054] For example, the Ministry of Land, Infrastructure, Transport and Tourism Notification No. 1641 prescribes the numerical values ​​of the allowable tensile and shear stresses for the axial cross section of a drilling tapping screw in a joint using a drilling tapping screw. 2 ) the tensile and shear forces are calculated using the following formula: Tensile: 0.51 (t2 / d) F Shear: 2.2η 0.5 (t2 / d) 1.5 F, 0.43{0.6+12(t2 / d)}·(t1 / d)F, or 0.43{1.5+6.7(t1 / d)}·(t2 / d)F Whichever is smaller F: Standard strength (N / mm 2 ) η: Influence coefficient related to the thickness ratio of the joined thin lightweight steel plates, calculated using the following formula The numerical value η=3.1-5.6(t1 / t2)+3.5(t1 / t2) 2 d: Nominal diameter of drilling tapping screw (mm) t1: Thickness of the thin lightweight steel plate on the screw head side (mm) t2: Thickness of the thin lightweight steel plate on the screw tip side (mm) Table 2 shows the tensile strength and shear strength values ​​calculated from the data values ​​in Table 1 using the above formula, for example. [Table 1] [Table 2]

[0055] As shown in Table 2, a single fastening member DB2 can be expected to have a shear strength that is approximately five times greater than the tensile strength expected from a single fastening member DB1. Therefore, by using the attachment plate 10 according to this embodiment, which enables the gantry foundation 1 to be fixed to the inclined portion 123 of the deck plate 120, the gantry foundation 1 is more firmly attached to the deck plate 120 than when the gantry foundation 1 is fixed only to the crest portion 121 of the deck plate 120. This allows the gantry foundation 1 to be stably fixed to the deck plate 120. Furthermore, compared to when the attachment plate 10 is attached only to the crest portion 121 of the deck plate 120, the number of fastening members to be driven can be reduced to obtain a shear strength τ that is the same magnitude as the tensile strength σ.

[0056] Furthermore, in this embodiment, the attachment plate 10 is attached to the deck plate 120 at the fixed leg portion 13 and the mounting portion 11, so that the resistance of the platform foundation 1 can be considered not only as the shear strength τ but also as the tensile strength σ, thereby achieving higher strength.

[0057] [Variation 1] 6 is a diagram showing the configuration of an attachment plate 10A according to Modification 1. In the attachment plate 10A, the same parts as those in the attachment plate 10 are given the same reference numerals, and the description thereof will be omitted.

[0058] While the attachment plate 10 according to the above embodiment is adapted to be fitted onto one peak portion 121, the attachment plate 10A according to Modification 1 is adapted to be fitted across two peak portions 121. Note that the attachment plate 10A may be formed so that it can be fitted across three or more peak portions 121.

[0059] The mounting portion 11 of the attachment plate 10 according to the first modification is formed, for example, so as to cover two peaks 121 adjacent in the short-side direction W and one valley bottom 122 between them. In the attached state, one of the pair of fixing legs 13 engages with the inclined portion 123 of one peak 121, and the other fixing leg 13 engages with the inclined portion 123 other than the inclined portion 123 adjacent to it in the short-side direction W, specifically, with the inclined portion 123 extending in a different direction in the adjacent peak 121.

[0060] The attachment plate 10A according to the first modification can achieve the same effect as the attachment plate 10 in terms of the resistance to external forces acting on the frame foundation 1, and also allows the frame 30 to be installed between the two peaks 121 of the deck plate 120, increasing the degree of freedom in installing the frame 30 on the attachment plate 10A. In other words, with the attachment plate 10A, the frame 30 can also be installed at a position corresponding to the valley bottom 122. This allows the installation position of the frame 30 to be flexibly adjusted to accommodate the position where the equipment 200 is installed.

[0061] [Variation 2] Fig. 7A is a diagram showing the configuration of an attachment plate 10B according to Modification 2. Fig. 7B is a diagram showing the attachment plate 10B according to Modification 2 fixed to a deck plate 120. For attachment plate 10B, the same parts as those of attachment plate 10 are given the same reference numerals, and their description will be omitted.

[0062] In the attachment plate 10B according to the second modification, each of the pair of fixing legs 13 has a hook-shaped claw portion (engagement portion) 14 at the tip portion opposite the mounting portion 11. The attachment plate 10B engages with a bulging portion 124 of the deck plate 120 at the claw portion 14. Note that the attachment plate 10B may also be fastened to the bulging portion 124 at the claw portion 14 with a screw, nail, or the like.

[0063] The claws 14 of each fixed leg 13 are formed in an arc shape and extend away from each other and then toward each other. When the claws 14 are engaged with the bulges 124, the tips of the claws 14 enter the engagement grooves 125. In the attached state, the attachment plate 10B is fixed to the deck plate 120 in the longitudinal direction L by a plurality of fastening members DB2 on the side of the attachment portion 11 of the fixed leg 13 relative to the claws 14.

[0064] The attachment plate 10B according to the second modification can achieve the same effect as the attachment plate 10 in terms of resistance to external forces acting on the gantry foundation 1. Furthermore, because the attachment plate 10B has the claw portions 14, it can be easily attached to the deck plate 120 during construction by fitting the attachment plate 10B into the deck plate 120, and it is possible to prevent the attachment plate 10B from shifting in position relative to the deck plate 120. Furthermore, because the claw portions 14 fit into the engagement grooves 125 of the deck plate 120 in the attached state, it is possible to ensure that the claw portions 14 can resist external forces that might pull out the gantry foundation 1.

[0065] [Variation 3] Fig. 8A is a diagram showing the configuration of an attachment plate 10C according to Modification 3. Fig. 8B is a diagram showing the attachment plate 10C according to Modification 3 fixed to a deck plate 120. For attachment plate 10C, the same parts as those of attachment plate 10 are given the same reference numerals, and their description will be omitted.

[0066] In the attachment plate 10C according to the third modification, the mounting portion 11 has a dimension in the short side direction W that is larger than the dimension in the short side direction W of the peak portion 121 of the deck plate 120, and has an extending end portion 111 that protrudes from the peak portion 121 in the short side direction W. In the attached state, the extending end portion 111 protrudes in the short side direction W from the peak portion 121.

[0067] Each of the fixed legs 13 of the attachment plate 10C has an extending leg portion 15 that extends from the extending end portion 111 of the mounting portion 11 at a right angle or a nearly right angle to the mounting portion 11, and an abutment portion 16 that abuts against the inclined portion 123, and has a mechanism for resisting a vertical load from the extending end portion 111. In the attached state, a space S is defined between the deck plate 120 and the attachment plate 10C by the inclined portion 123 of the deck plate 120, the extending end portion 111 of the mounting portion 11 of the attachment plate 10C, and the extending leg portion 15. Note that the angle formed between the extending end portion 111 and the extending leg portion 15 is not limited to a right angle or a nearly right angle.

[0068] The abutment portions 16 are provided on the opposite side of the extending leg portions 15 from the mounting portions 11, and extend in directions away from each other. In the mounted state, the abutment portions 16 are formed to abut against the inclined portions 123 and extend along the inclined portions 123 toward the valley bottoms 122. The attachment plate 10C according to Modification 3 is fixed at the abutment portions 16 of the fixing legs 13 to the inclined portions 123 of the deck plate 120 with fastening members DB2.

[0069] The attachment plate 10C according to the third modification can achieve the same effect as the attachment plate 10 in terms of resistance to external forces acting on the frame foundation 1, and can also support the roof insulation material 140 at the extending end portion 111. This can prevent the roof insulation material 140 from being cantilevered around the frame foundation 1, thereby preventing damage such as cracking of the roof insulation material 140.
