Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in recent years, the weight of roofs has tended to increase. For example, when solar panels are arranged on a roof as in Patent Document 1, or when the size of the roof is increased, the weight of the roof increases. In order to hold such a roof with an increased weight, it is necessary to increase the strength of the columns holding the roof. As means for increasing the strength of the columns, increasing the size of the columns or increasing the thickness of the members constituting the columns can be considered.

[0005] However, if the above means are taken, the weight of the columns increases. Handling columns with a large weight is a great burden for workers performing the construction work of the roof structure. As a result, it was considered that the efficiency of the construction work of the roof structure would be adversely affected.

[0006] One aspect of the present disclosure aims to improve the efficiency of the construction work of the roof structure.

Means for Solving the Problems

[0007] To solve the above problems, a roof structure according to one aspect of the present disclosure comprises a support column composed of a pair of support members, a reinforcing member disposed inside the support column, a roof held by the support column, a first connecting member connecting the pair of support members, and a second connecting member connecting the support members and the reinforcing member. [Effects of the Invention]

[0008] According to one aspect of this disclosure, the efficiency of construction work for roof structures can be improved. [Brief explanation of the drawing]

[0009] [Figure 1] This is a diagram illustrating the general configuration of a carport. [Figure 2] This is a plan view of the roof structure as seen from above. [Figure 3] This is a cross-sectional view along the line A-A shown in Figure 1. [Figure 4] This diagram shows the configuration of a pair of support members and reinforcing members. [Figure 5] This is a side view of the support column as it is erected on the ground, seen from the left side. [Figure 6] This diagram shows the construction method for a carport. [Figure 7] This is a schematic diagram showing the general configuration of a carport in a modified form. [Modes for carrying out the invention]

[0010] [Embodiment 1] An embodiment of this disclosure will be described in detail below. In the following description, the up-down direction, the front-back direction, and the left-right direction are defined as shown by arrows in Figure 1, etc. The up-down direction is the vertical direction. The front-back direction and the left-right direction correspond to the horizontal direction, respectively. In this embodiment, the horizontal direction is the direction parallel to the ground 6.

[0011] [Overview of Carport 1] The general configuration of carport 1 will be described with reference to Figure 1. Figure 1 is a diagram showing the general configuration of carport 1. Reference numeral 100 in Figure 1 is a side view of carport 1 seen from the left side. Reference numeral 101 in Figure 1 is a front view of carport 1 seen from the front. Carport 1 is an example of a roof structure.

[0012] As shown by reference numeral 100 in Figure 1, the carport 1 comprises a roof 2 and support columns 3. The support columns 3 are erected on the ground 6 with their longitudinal direction oriented vertically. The lower ends of the support columns 3 are fixed to a buried concrete foundation (not shown). The support columns 3 support the roof 2. The detailed configuration of the support columns 3 will be described later.

[0013] The roof 2 comprises a roof body 20. The roof 2 may also include beams 4 attached to the upper part of the support columns 3. The roof 2 may also include braces 5 that reinforce the connection between the support columns 3 and the beams 4. The beams 4 and braces 5 are made of metal, such as aluminum. The beams 4 and braces 5 may be formed by extrusion molding.

[0014] The roof body 20 is positioned with a gap between it and the ground 6 and covers the parking space located in front of the support column 3. In this embodiment, the roof body 20 is attached to the upper part of the beam 4 and directly supported by the beam 4. That is, the support column 3 holds the roof 2 by attaching the beam 4, which directly supports the roof body 20, to the upper part of the support column 3. The roof 2 may also be held by the support column 3 by directly attaching the roof body 20 to the upper part of the support column 3. Furthermore, the roof body 20 is not limited to being supported at the upper part of the beam 4. The roof body 20 may also be suspended below the beam 4 by a suspension member. In this case, the roof 2 is equipped with the suspension member, and the support column 3 holds the roof 2 by attaching the beam 4, on which the suspension member is provided, to the upper part of the support column 3.

[0015] The roof main body 20 is inclined in the front-rear direction such that the rear end of the roof main body 20 is lower than the front end of the roof main body 20. By inclining the roof main body 20, rainwater can be collected on the rear end side of the roof main body 20. Note that the roof main body 20 may be inclined in the front-rear direction such that the rear end of the roof main body 20 is higher than the front end of the roof main body 20, or may be inclined in the left-right direction. As shown by reference numeral 101 in FIG. 1, the roof 2 is held by two support columns 3. Note that the roof 2 may be held by one support column 3 or may be held by three or more support columns 3.

[0016] 〔Outline of roof main body 20〕 Next, referring to FIG. 2, an example of the configuration of the roof main body 20 will be described. FIG. 2 is a plan view of the roof main body 20 as viewed from above. The roof main body 20 is composed of a main roof 21, purlins 22, and a solar panel 26. In FIG. 2, for the sake of clarity of the drawing, reference numerals are attached only to some of the main roof 21, purlins 22, and solar panel 26.

[0017] The main roof 21 is a long member and is supported on the upper part of the beam 4 such that its longitudinal direction is in the left-right direction (the direction perpendicular to the beam 4). The purlins 22 are short members and are attached between the main roofs 21 arranged in the front-rear direction. The main roof 21 and the purlins 22 are members made of metal such as aluminum, for example. The main roof 21 and the purlins 22 may be formed by extrusion molding.

[0018] The solar panel 26 is arranged in the space partitioned by the main roof 21 and the purlins 22. The solar panel 26 is a panel capable of performing solar power generation that generates electric power from solar energy. Note that the roof main body 20 is not limited to a configuration in which the solar panel 26 is installed. For example, a resin panel or a metal roofing material such as aluminum may be installed on the roof main body 20.

[0019] The roof main body 20 may be provided with a front water drainage 23. The front water drainage 23 is provided at the front end of the roof main body 20 to prevent rainwater from falling downward from the front end of the roof main body 20. In the present embodiment, the front water drainage 23 is attached to the main house 21 located at the foremost part of the roof main body 20.

[0020] The roof main body 20 may be provided with side water drainages 24. The side water drainages 24 are provided at the left and right ends of the roof main body 20 respectively to prevent rainwater from falling downward from the left and right ends of the roof main body 20. In the present embodiment, the side water drainage 24 located on the left side of the roof main body 20 is attached to each purlin 22 attached to the left end portion of the main house 21 of the roof main body 20. The side water drainage 24 located on the right side of the roof main body 20 is attached to each purlin 22 attached to the right end portion of the main house 21 of the roof main body 20.

[0021] The roof main body 20 may be provided with a rain gutter 25. The rain gutter 25 is provided at the rear end of the roof main body 20 to collect rainwater falling downward from the rear end of the roof main body 20. In the present embodiment, the rain gutter 25 is attached to the main house 21 located at the rearmost part of the roof main body 20. The front water drainage 23, the side water drainages 24, and the rain gutter 25 are members made of metal or resin such as aluminum, for example.

[0022] 〔Outline of the column 3〕 Next, referring to FIGS. 3 to 5, an example of the configuration of the column 3 will be described. FIG. 3 is a cross-sectional view taken along the line A-A shown in FIG. 1. FIG. 4 is a diagram showing the configuration of a pair of support members 30 and reinforcing members 40. FIG. 5 is a side view of the column 3 in a state of being built on the ground 6 as viewed from the left side. In FIG. 5, the internal space of the column 3 and the reinforcing members 40 arranged inside the column 3 are shown by broken lines, and the beam 4, the square rod 5, the column cover 50, and the gutter cover 60 attached to the column 3 are shown by two-dot chain lines.

[0023] As shown in Figure 3, the support column 3 is composed of a pair of support members 30. In this embodiment, the pair of support members 30 are arranged facing each other in the left-right direction. Alternatively, the pair of support members 30 may be arranged facing each other in the front-rear direction. The support column 3, composed of the pair of support members 30, is open at both ends in the vertical direction.

[0024] In the following description, the left-hand support member 30 of the pair of support members 30 may be referred to as "support member 30L," and the right-hand support member 30 of the pair of support members 30 may be referred to as "support member 30R." Furthermore, when support member 30L and support member 30R are not distinguished, they are collectively referred to as "support member 30."

[0025] The support member 30 is made of a metal such as aluminum and is a long member. The support member 30 may be formed by extrusion molding. Furthermore, the support member 30L and the support member 30R may have the same cross-sectional shape in the horizontal direction. Note that the same cross-sectional shape in the horizontal direction of the support member 30L and the support member 30R includes a state in which the cross-sectional shape is completely identical, as well as a state in which the cross-sectional shape is substantially identical. "Substantially identical cross-sectional shape" means a state in which the cross-sectional shape is slightly different, for example, due to the formation of an insertion hole in the support member 30 after molding, and due to tolerances that occur during the manufacturing process of the support member 30.

[0026] The support member 30 has a first wall portion 31 and a second wall portion 32. The first wall portion 31 is a wall portion that extends along the front-rear direction in a cross-sectional view in the horizontal direction. The second wall portion 32 is a wall portion that extends from both ends of the first wall portion 31 in the front-rear direction toward the left-right direction. More specifically, the base end of the front second wall portion 32 is connected to the front end of the first wall portion 31, and the base end of the rear second wall portion 32 is connected to the rear end of the first wall portion 31.

[0027] When the pair of support members 30 are connected, the horizontal cross-sectional shape of the first wall portion 31 and the second wall portion 32 is rectangular. When the pair of support members 30 are connected, a rectangular space is formed by the inner wall surfaces of the first wall portion 31 and the second wall portion 32. When the pair of support members 30 are connected, the horizontal cross-sectional shape of the first wall portion 31 and the second wall portion 32 may be a hollow circle or a hollow polygon (for example, a pentagon or a hexagon). Also, when the pair of support members 30 are connected, the space formed by the inner wall surfaces of the first wall portion 31 and the second wall portion 32 may be circular or polygonal.

[0028] Ribs may be formed on the inner wall surfaces of the first wall portion 31 and the second wall portion 32, respectively. The second wall portion 32 may be provided with a connecting portion 33 to which a bolt B1 is attached. The second wall portion 32 also has an insertion hole (not shown) into which a bolt B2 is inserted. In the following description, the insertion hole in the second wall portion 32 into which the bolt B2 is inserted will be simply referred to as the "insertion hole of the second wall portion 32". The insertion hole of the second wall portion 32 located on the front side of the support member 30 and the insertion hole of the second wall portion 32 located on the rear side of the support member 30 may be formed at the same position in the vertical direction.

[0029] As shown in Figures 3 and 4, the connecting portion 33 is composed of a protruding wall portion 331 and an extending wall portion 332. The protruding wall portion 331 is a wall portion that protrudes from the outer wall surface of the second wall portion 32 toward the outside of the support column 3. That is, the protruding wall portion 331 is a wall portion that protrudes away from the center C0 in the horizontal cross-section of the support column 3.

[0030] In this embodiment, the protruding wall portion 331 is a wall portion that protrudes in the front-rear direction from the outer wall surface of the second wall portion 32. The base end of the protruding wall portion 331 is connected to the second wall portion 32. The protruding wall portion 331 protrudes in the front-rear direction from the central portion of the second wall portion 32 in the left-right direction. The insertion hole of the second wall portion 32 is located on the side of the first wall portion 31 that is located in the left-right direction. The protruding wall portion 331 has an insertion hole (not shown) into which a bolt B1 is inserted. In the following description, the insertion hole of the protruding wall portion 331 into which the bolt B1 is inserted will be simply referred to as the "insertion hole of the protruding wall portion 331". By inserting the bolt B1 into the insertion hole of the protruding wall portion 331 of the pair of support members 30, the pair of support members 30 are positioned relative to each other.

[0031] The extended wall portion 332 is a wall portion that extends from the front end of the protruding wall portion 331 in the front-rear direction in the left-right direction. The base end of the extended wall portion 332 is connected to the front end of the protruding wall portion 331. The extended wall portion 332 extends in the same direction as the extension direction of the second wall portion 32. In the left-right direction, the front end of the extended wall portion 332 is located at approximately the same position as the front end of the second wall portion 32. As shown in Figure 3, the extended wall portion 332 has a screw hole (not shown) into which a screw 51 or screw 66 is screwed.

[0032] When the support member 30L and the support member 30R are connected, the tip of the second wall portion 32 of the support member 30L and the tip of the second wall portion 32 of the support member 30R are in contact with each other. Also, the tip of the extended wall portion 332 of the support member 30L and the tip of the extended wall portion 332 of the support member 30R are in contact with each other.

[0033] Mounting portions 34 are formed at the front and rear ends of the first wall portion 31, to which a support column cover 50 or a gutter cover 60 is attached. Screw holes (not shown) are formed in the mounting portions 34, into which screws 51 or screws 61 are screwed.

[0034] The reinforcing member 40 reinforces the support column 3. The reinforcing member 40 is made of metal such as iron and is a long member. Preferably, the reinforcing member 40 is made of a different material than the pair of support members 30, and more preferably, it is made of a material with higher hardness than the material used for the pair of support members 30. The reinforcing member 40 is placed inside the support column 3. More specifically, the reinforcing member 40 is placed in a rectangular space enclosed by the inner wall surface of the first wall portion 31 and the inner wall surface of the second wall portion 32 of the pair of support members 30. A design clearance is provided between the reinforcing member 40 and the support members 30. More specifically, a design clearance is provided between the reinforcing member 40 and the ribs formed on the inner wall surface of the first wall portion 31, and between the reinforcing member 40 and the ribs formed on the inner wall surface of the second wall portion 32. The clearance between the reinforcing member 40 and the support members 30 takes into account the tolerances that occur in the support members 30 or the reinforcing member 40.

[0035] The reinforcing member 40 has a rectangular horizontal cross-sectional shape and is hollow and cylindrical. The horizontal cross-sectional shape of the reinforcing member 40 may also be circular or polygonal (for example, a pentagon or hexagon). Screw holes (not shown) into which bolts B2 are screwed are formed on the front and rear surfaces of the reinforcing member 40. By screwing the bolts B2, inserted into the insertion holes in the second wall portion 32, into the screw holes in the reinforcing member 40, the reinforcing member 40 and the support member 30 are positioned relative to each other.

[0036] As shown in Figure 3, a support column cover 50 is attached to the front of the support column 3. The support column cover 50 covers the second wall portion 32 and the connecting portion 33 located on the front side of the support member 30. The support column cover 50 is made of a metal such as aluminum or a resin material. The support column cover 50 is attached to the mounting portion 34 and the extended wall portion 332 by screws 51. The support column cover 50 has insertion holes (not shown) into which the screws 51 are inserted.

[0037] A gutter cover 60 is attached to the rear of the support column 3. The gutter cover 60 covers the second wall portion 32 and the connecting portion 33 located on the rear side of the support member 30. The gutter cover 60 is made of a metal such as aluminum or a resin material. Inside the gutter cover 60 are a downpipe (not shown) for draining rainwater collected in the rain gutter 25 to the ground 6 or a drainage ditch, and wiring cables for solar panels (not shown), etc.

[0038] The gutter cover 60 has an insertion hole (not shown) into which a screw 61 is inserted. The gutter cover 60 is attached to a mounting portion 34 located on the rear side of the support member 30 by the screw 61. The gutter cover 60 is also attached to the support member 30 via a spacer 65. The gutter cover 60 is attached to the spacer 65 by a screw 62. The spacer 65 is attached to the extended wall portion 332 of the support member 30 by a screw 66.

[0039] Bolt B1 connects a pair of support members 30. Bolt B1 is an example of a first connecting member. More specifically, support members 30L and 30R are connected by screwing nuts onto bolt B1, which is inserted into the insertion hole in the protruding wall portion 331 of support member 30L and the insertion hole in the protruding wall portion 331 of support member 30R.

[0040] Bolt B2 connects the support member 30 and the reinforcing member 40. Bolt B2 is an example of a second connecting member. More specifically, bolt B2, which is inserted into the insertion hole in the second wall portion 32 of the support member 30, is screwed into the threaded hole of the reinforcing member 40, which is formed at a position corresponding to the insertion hole in the second wall portion 32 into which bolt B2 is inserted. In this way, the support member 30 and the reinforcing member 40 are connected by bolt B2.

[0041] The direction in which support member 30L and support member 30R are connected by bolt B1 is defined as the first connection direction. The direction in which support member 30 and reinforcing member 40 are connected by bolt B2 is defined as the second connection direction. The first connection direction and the second connection direction intersect in the horizontal direction. The first connection direction is the direction in which the pair of support members 30 face each other. In this embodiment, the first connection direction is the left-right direction. That is, when support member 30L and support member 30R are connected by bolt B1, the axial direction of bolt B1 is the left-right direction. The second connection direction is the direction that intersects the direction in which the pair of support members 30 face each other. In this embodiment, the second connection direction is the front-back direction. That is, when support member 30 and reinforcing member 40 are connected by bolt B2, the axial direction of bolt B2 is the front-back direction. In this embodiment, the first connection direction and the second connection direction are orthogonal in the horizontal direction. In other words, bolts B1 and B2 are positioned so that their axial directions are perpendicular to each other in the horizontal direction.

[0042] The shortest horizontal distance between the center C0 of the support column 3 and the bolt B1 connecting the pair of support members 30 is defined as the first distance L1, and the shortest horizontal distance between the center C0 and the bolt B2 connecting the support member 30 and the reinforcing member 40 is defined as the second distance L2. The second distance L2 is shorter than the first distance L1. The center C0 is the center of the horizontal cross-section of the first wall portion 31 and the second wall portion 32. The center C0 is also the center of the horizontal cross-section of the space formed by the inner wall surfaces of the first wall portion 31 and the second wall portion 32 where the reinforcing member 40 is arranged. The bolt B2 connecting the support member 30 and the reinforcing member 40 is located closer to the center C0 than the bolt B1 connecting the pair of support members 30. That is, the insertion hole in the second wall portion 32 is located closer to the center C0 in the horizontal direction than the insertion hole in the protruding wall portion 331. In this embodiment, the bolt B1 is located outside the outer wall surface of the second wall portion 32.

[0043] As shown in Figure 5, the bolt B1 connecting the pair of support members 30 and the bolt B2 connecting the support member 30 and the reinforcing member 40 are spaced apart in the vertical direction. That is, the insertion hole in the protruding wall portion 331 and the insertion hole in the second wall portion 32 are spaced apart in the vertical direction. When viewed from the horizontal direction, it is preferable that the bolt B2 connecting the support member 30 and the reinforcing member 40 is located in a position that does not overlap with the bolt B1 connecting the pair of support members 30.

[0044] The reinforcing member 40 is embedded together with the support column 3. The lower end of the reinforcing member 40 is fixed together with the support column 3 to the concrete that forms the foundation of the support column 3. Note that in Figure 5, the concrete that forms the foundation of the support column 3 is not shown. The support column cover 50 and the gutter cover 60 are not embedded.

[0045] A beam 4 is attached to the upper part of a pair of support members 30 by bolts B4. More specifically, a notch (not shown) is formed at the upper end of the connected pair of support members 30 (support columns 3) into which the beam 4 is fitted. These notches are formed at the upper end of the second wall portion 32 located on the front and rear sides of each support member 30, and at the upper end of the extended wall portion 332 of the connecting portion 33 located on the front and rear sides, respectively. The beam 4 is fitted into the notches formed in the pair of support members 30 and is attached to the protruding wall portion 331 of the connecting portion 33 located on the front and rear sides of each support member 30 using bolts B4. That is, at the upper part of the support member 30, an insertion hole is formed in the protruding wall portion 331 into which the bolts B4 are inserted.

[0046] Furthermore, the brace 5 is attached to the support member 30 by bolts B5. More specifically, a notch (not shown) is formed at the rear end of the brace 5 into which the connecting portion 33 located on the front side of the pair of connected support members 30 is fitted. The brace 5 is attached to the protruding wall portion 331 of the connecting portion 33 located on the front side of each support member 30 using bolts B5 when the connecting portion 33 of each support member 30 is fitted into the notch of the brace 5. That is, in the support member 30, an insertion hole is formed in the protruding wall portion 331 to which the brace 5 is attached, into which the bolts B5 are inserted.

[0047] The reinforcing member 40 is not attached to the roof body 20, beam 4, or brace 5. That is, the reinforcing member 40 does not directly hold the roof 2. Also, the roof body 20, beam 4, and brace 5 are not attached to the support column cover 50 and the gutter cover 60. It is preferable that the reinforcing member 40 is housed inside the support column 3. It is preferable that the vertical length of the reinforcing member 40 is shorter than the vertical length of the support member 30. In this embodiment, the upper end of the reinforcing member 40 when it is positioned inside the support column 3 is located below the position of the bolt B4 for attaching the beam 4 to the support column 3.

[0048] With the carport 1 configuration described above, since the support column 3 is composed of a pair of support members 30, it is possible to connect one of the support members 30L to the reinforcing member 40, and then connect the other support member 30R to the reinforcing member 40. This makes it easier to position the heavy reinforcing member 40 in the appropriate location inside the support column 3. In addition, since the support column 3 is composed of a pair of support members 30, the weight per support member 30 is reduced. This improves the efficiency of the construction work for the carport 1.

[0049] Alternatively, for example, a configuration in which the reinforcing member 40 is placed inside the support column 3, which is composed of a pair of support members 30, using only bolts B2 to connect the support member 30 and the reinforcing member 40. In this case, when the pair of support members 30 are connected to the reinforcing member 40 using only bolts B2, vertical misalignment of the pair of support members 30 connected to the reinforcing member 40 is likely to occur. However, the carport 1 described above is equipped with bolts B1 to connect the pair of support members 30. Therefore, the bolts B1 make it easy to position the pair of support members 30 connected to the reinforcing member 40 in the vertical direction. This improves the efficiency of the construction work of the carport 1.

[0050] Furthermore, the intersecting of the first and second connection directions in the horizontal direction allows for adjustment of the position of the reinforcing member 40 relative to the support column 3 in both connection directions. This makes it easier to position the reinforcing member 40 at the center of the interior of the support column 3 in the horizontal direction.

[0051] Furthermore, bolt B1, which connects the pair of support members 30, and bolt B2, which connects the support member 30 and the reinforcing member 40, are spaced apart vertically. Therefore, when connecting the pair of support members 30 using bolt B1, and when connecting the support member 30 and the reinforcing member 40 using bolt B2, bolts B1 and B2 are less likely to interfere with each other. This makes it possible to further improve the efficiency of the construction work of the carport 1.

[0052] Furthermore, by making the second distance L2 shorter than the first distance L1, the bolt B2 can be brought closer to the reinforcing member 40. This strengthens the connection between the support member 30 and the reinforcing member 40 by the bolt B2. Also, since the pair of support members 30 are connected by a bolt B1 positioned away from the reinforcing member 40, it is possible to prevent the pair of support members 30 from separating.

[0053] Furthermore, by making the horizontal cross-sectional shape of the pair of support members 30 the same, the pair of support members 30 can be standardized. This reduces the manufacturing cost of the pair of support members 30.

[0054] [Construction method for carport 1] Next, the construction method of carport 1 will be explained with reference to Figure 6. Figure 6 is a diagram showing the construction method of carport 1. Note that, in Figure 6, for the sake of readability, the reference numerals for some components have been omitted.

[0055] First, a first temporary fixing step S1 (hereinafter simply referred to as step S1) is performed in which one of the pair of support members 30, support member 30L, is temporarily fixed to the reinforcing member 40 using bolt B2. More specifically, in step S1, the reinforcing member 40 is positioned above the support member 30L, which is tilted horizontally. In step S1, the support member 30L is temporarily fixed to the reinforcing member 40 using bolt B2.

[0056] Next, a second temporary fixing step S2 (hereinafter simply referred to as step S2) is performed in which the other support member 30R of the pair of support members 30 is temporarily fixed to the reinforcing member 40 using bolt B2. More specifically, in step S2, the support member 30R is positioned above the reinforcing member 40, which is tilted horizontally. In step S2, the support member 30R is temporarily fixed to the reinforcing member 40 using bolt B2.

[0057] Next, a connecting step S3 (hereinafter simply referred to as step S3) is performed in which a pair of support members 30 are connected using bolt B1, and the pair of support members 30 are connected to a reinforcing member 40 using bolt B2. Specifically, in step S3, support members 30L and 30R are temporarily fixed using bolt B1. In step S3, with support members 30L and 30R temporarily fixed, the position of the reinforcing member 40 relative to each of the support members 30L and 30R is adjusted. At this time, support members 30L and 30R are temporarily fixed to the reinforcing member 40.

[0058] In step S3, after adjusting the position of the reinforcing member 40 relative to each of the support members 30L and 30R, the support members 30L and 30R are fixed by tightening bolt B1. Furthermore, after adjusting the position of the reinforcing member 40 relative to each of the support members 30L and 30R, the reinforcing member 40 is fixed to each of the support members 30L and 30R by tightening bolt B2. As a result, the support members 30L and 30R are connected, and each of the support members 30L and 30R is connected to the reinforcing member 40.

[0059] Next, an attachment process S4 (hereinafter simply referred to as process S4) is performed to attach the beam 4 and the brace 5 to the support column 3 to which the reinforcing member 40 is connected. In process S4, the rear end of the beam 4 is attached to the upper part of the support member 30 that constitutes the support column 3 using bolts B4. In process S4, the rear end of the brace 5 is attached to the upper part of the support member 30 that constitutes the support column 3 using bolts B5. In process S4, the front end of the brace 5 is attached to the front of the beam 4 using bolts (not shown).

[0060] Next, a temporary support fixing process S5 (hereinafter simply referred to as process S5) is performed, in which the support column 3, to which the reinforcing member 40 is connected, is temporarily fixed to the foundation hole 7 formed in the ground 6. In process S5, the foundation hole 7 is excavated in the ground 6. In process S5, the support column 3, to which the beam 4 and diagonal brace 5 are attached, is erected in the foundation hole 7 using heavy machinery or the like. In process S5, the support column 3 erected in the foundation hole 7 is temporarily fixed in the foundation hole 7.

[0061] Next, the roof body installation process S6 (hereinafter simply referred to as process S6) is performed, in which the roof body 20 is attached to the support columns 3 that are temporarily fixed in the foundation holes 7. In process S6, the purlins 21 are attached to the beams 4. At this time, a front flashing 23 is attached to the purlin 21 located furthest forward, and a rain gutter 25 is attached to the purlin 21 located furthest rear. In process S6, secondary beams 22 are attached to the purlins 21 attached to the beams 4. In process S6, after the secondary beams 22 are attached to the purlins 21, side flashings 24 are attached to the right end and the left end of the roof body 20. More specifically, the side flashings 24 are attached to the secondary beam 22 located furthest right and the secondary beam 22 located furthest left.

[0062] After step S6, the following steps are performed: pouring concrete into the foundation holes 7, installing solar panels 26 on the roof body 20, and attaching support column covers 50 and gutter covers 60 to the support columns 3. If the panels installed on the roof body 20 are made of resin, the work of installing the resin panels on the roof body 20 may be performed in step S6.

[0063] According to the above construction method, by temporarily fixing each of the pair of support members 30 to the reinforcing member 40 with bolt B2, it is possible to adjust the position of the reinforcing member 40 relative to each of the pair of support members 30. Furthermore, since the pair of support members 30 are temporarily fixed with bolt B1, the positions of the support members 30 are already adjusted. Therefore, it is possible to adjust the position of the reinforcing member 40 relative to each of the pair of support members 30 while simultaneously adjusting the positions of the support members 30 themselves. This improves the efficiency of the construction work for the carport 1.

[0064] [Variation] Referring to Figure 7, a modified carport 1A will be described. Figure 7 is a schematic diagram showing the general configuration of the modified carport 1A. For the sake of explanation, the same reference numerals are used for members having the same function as those described in the above embodiment, and their descriptions will not be repeated.

[0065] As shown in Figure 7, carport 1A is a gable-type carport in which multiple roof sections 20 are joined together. Carport 1A is an example of a roof structure. Carport 1A is a so-called rear-gable type in which the ends of the roof sections 20 located on the support column 3 side are joined together.

[0066] The roof body 20 of roof 2, shown on the left side of Figure 7 and supported by the support column 3, slopes upward as it moves away from the support column 3. Conversely, the roof body 20 of roof 2, shown on the right side of Figure 7 and supported by the support column 3, slopes downward as it moves away from the support column 3. In other words, the roof body 20 of roof 2 shown on the right side of Figure 7 is sloped such that its rear end is lower than its front end. That is, rainwater flowing over the tops of the two roof bodies 20 of carport 1A flows from left to right in Figure 7.

[0067] Furthermore, in Figure 7, the roof body 20 of the roof 2, which is supported by the support columns 3 shown on both sides in the left-right direction of the paper, is sloped such that its rear end is lower than its front end. Also, the carport 1A is not limited to a rear-gabled type, but may also be a Y-shaped gabled type.

[0068] [Other Embodiments] In the embodiment described above, a bolt B1 is used to connect the pair of support members 30, but the configuration is not limited to this. As the first connecting member for connecting the pair of support members 30, for example, a U-shaped connecting member may be used. When the pair of support members 30 are connected, the horizontal cross-section of the U-shaped connecting member is U-shaped. For example, the U-shaped connecting member connects the pair of support members 30 by sandwiching the respective connecting portions 33 of the pair of support members 30. In this case, after connecting the pair of support members 30, the U-shaped connecting member is fixed to the respective connecting portions 33 of the pair of support members 30 by screws or bolts. Alternatively, the U-shaped connecting member may connect the pair of support members 30 by sandwiching the respective first wall portions 31 of the pair of support members 30. Furthermore, a bolt B2 is used to connect the support member 30 and the reinforcing member 40, but the configuration is not limited to this. For example, a screw or bolt may be used as the second connecting member that connects the support member 30 and the reinforcing member 40.

[0069] Furthermore, although carports 1 and 1A were described as examples of roof structures in the embodiments described above, the roof structure is not limited to carports 1 and 1A. The roof structure of the present invention is applicable, for example, to a structure that supports a roof covering a predetermined space such as a bicycle parking space or a sidewalk.

[0070] 〔summary〕 A roof structure according to Embodiment 1 of the present disclosure comprises a support column composed of a pair of support members, a reinforcing member disposed inside the support column, a roof held by the support column, a first connecting member connecting the pair of support members, and a second connecting member connecting the support members and the reinforcing member.

[0071] According to the above embodiment 1, since the support column is composed of a pair of support members, it is possible to connect one of the support members to the reinforcing member, and then connect the other support member to the reinforcing member. This makes it easier to place the heavy reinforcing member inside the support column. In addition, since the support column is composed of a pair of support members, the weight per support member is reduced. This improves the efficiency of construction work for the roof structure.

[0072] In the roof structure according to embodiment 2 of the present disclosure, the first connecting direction, which is the direction in which the pair of support members are connected by the first connecting member, and the second connecting direction, which is the direction in which the support members and the reinforcing member are connected by the second connecting member, may be configured to intersect in the horizontal direction.

[0073] According to embodiment 2 described above, the first connection direction and the second connection direction intersect in the horizontal direction, making it possible to adjust the position of the reinforcing member relative to the support column in both connection directions. This makes it easier to position the reinforcing member at the center of the inside of the support column in the horizontal direction.

[0074] In the roof structure according to embodiment 3 of the present disclosure, the first connecting member in which the pair of support members are connected and the second connecting member in which the support members and the reinforcing member are connected may be configured to be spaced apart in the vertical direction, as in embodiment 1 or 2 described above.

[0075] According to embodiment 3 described above, the first connecting member, which connects a pair of support members, and the second connecting member, which connects a support member and a reinforcing member, are spaced apart in the vertical direction. Therefore, when connecting a pair of support members using the first connecting member, and when connecting a support member and a reinforcing member using the second connecting member, interference between the first connecting member and the second connecting member is less likely. This makes it possible to further improve the efficiency of construction work for roof structures.

[0076] In any of the above embodiments 1 to 3, the roof structure according to embodiment 4 of the present disclosure may be configured such that the second distance, which is the shortest horizontal distance between the center of the horizontal cross-section of the support column and the second connecting member in a state in which the support member and the reinforcing member are connected, is shorter than the first distance, which is the shortest horizontal distance between the center and the first connecting member in a state in which the pair of support members are connected.

[0077] According to embodiment 4 described above, by making the second distance L2 shorter than the first distance L1, the second connecting member can be brought closer to the reinforcing member. This makes the connection between the support member and the reinforcing member by the second connecting member stronger. Furthermore, since the pair of support members are connected by the first connecting member which is positioned away from the reinforcing member, it is possible to prevent the pair of support members from separating.

[0078] In the roof structure according to aspect 5 of this disclosure, in any of the above aspects 1 to 4, the pair of support members may be configured such that their horizontal cross-sectional shapes are the same.

[0079] According to embodiment 5 described above, by making the horizontal cross-sectional shape of a pair of support members the same, the pair of support members can be made common. This makes it possible to reduce the manufacturing cost of the pair of support members.

[0080] A method for constructing a roof structure according to aspect 6 of the present disclosure is a method for constructing a roof structure comprising: a support column composed of a pair of support members; a reinforcing member disposed inside the support column; a roof held by the support column; a first connecting member connecting the pair of support members; and a second connecting member connecting the support members and the reinforcing member, the method comprising: a first temporary fixing step of using the second connecting member to temporarily fix one of the pair of support members to the reinforcing member; and using the second connecting member to temporarily fix the other of the pair of support members to the reinforcing member. The process includes a second temporary fixing step of temporarily fixing the support members, and a connecting step of connecting the pair of support members using the first connecting member and connecting each of the pair of support members to the reinforcing member using the second connecting member, wherein in the connecting step, after adjusting the position of the reinforcing member relative to each of the pair of support members in a state in which the pair of support members are temporarily fixed using the first connecting member and each of the pair of support members is temporarily fixed to the reinforcing member, the pair of support members are connected and the pair of support members are connected to the reinforcing member.

[0081] According to embodiment 6 described above, by temporarily fixing each of the pair of support members to the reinforcing member with the second connecting member, it is possible to adjust the position of the reinforcing member relative to each of the pair of support members. Furthermore, since the pair of support members are temporarily fixed by the first connecting member, the positions of the support members themselves are already adjusted. Therefore, it is possible to adjust the position of the reinforcing member relative to each of the pair of support members while simultaneously adjusting the positions of the support members themselves. This improves the efficiency of the construction work of the roof structure.

[0082] This disclosure is not limited to the embodiments described above, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of this disclosure. [Explanation of Symbols]
