[0015] Figure 6 is a cross-sectional view showing the roof structural body 1 of the first embodiment taken along line X4-X4 in Figure 5, with the internal structure of the pillars 2 and beams 4 shown by chain lines. Figure 7 is a cross-sectional view showing the roof structural body 1 of the first embodiment taken along line X5-X5 in Figure 5. Figure 7 schematically shows the roof structural body 1 with a reduced number of roof materials 20, 30 compared to the number of roof materials 20, 30 shown in Figure 5. As shown in the figure, the beam 4 is connected to the upper end of the support column 2 by a joint material 40, and projects upward from the support column 2 toward the installation location G. The support column 2 and the beam 4 are each formed to have a hollow shape, and the joint material 40 is inserted into the interior of the support column 2 and the interior of the beam 4. The joint material 40 is fixed to each of the support column 2 and the beam 4, and the beam 4 is supported by the support column 2 via the joint material 40.

[0016] The purlin 10 is located below the beams 4 and is attached to the beams 4, and is arranged vertically between the beams 4 and the roofing materials 20, 30. The roofing materials 20, 30 are covering materials that cover the installation location G of the roof structural body 1, and are attached to the purlin 10 to form the ceiling portion of the roof structural body 1. The multiple roofing materials 20, 30 include end roofing materials 20 and intermediate roofing materials 30, and are located below the purlin 10 and arranged in parallel below the purlin 10. The end roofing material 20 is the end roofing material 20 of the multiple roofing materials 20, 30, and is located at both ends in the arrangement direction of the multiple roofing materials 20, 30 (the longitudinal direction of the purlin 10). The intermediate roofing material 30 is the middle roofing material 30 of the multiple roofing materials 20, 30, located between the end roofing materials 20 on both sides of the arrangement direction of the multiple roofing materials 20, 30, and is located in the middle of the arrangement direction of the multiple roofing materials 20, 30.

[0017] The roof structure 1 is provided with connecting members 50 attached to the end portions 11 of the purlins 10. The end portions 11 of the purlins 10 are end portions on both sides in the longitudinal direction of the purlins 10, and connecting members 50 are attached to each of the end portions 11 on both sides of the purlins 10. At each of the end portions 11 on both sides of the purlins 10, an end roof member 20 is located below the end portion 11 of the purlins 10 and the connecting member 50 and attached to the purlins 10 and the connecting member 50. The connecting member 50 holds the end roof member 20 and connects it to the end portion 11 of the purlins 10. The end roof member 20 is located at both ends of the purlins 10 in the longitudinal direction of the multiple roof members 20, 30, and is held to the end portion 11 of the purlins 10 via the connecting members 50. The intermediate roof material 30 is not positioned below the end 11 of the main house 10 and the connecting material 50, but is arranged below the main house 10, between the end parts 11 on both sides of the main house 10 and between the connecting materials 50 on both sides.

[0018] The beams 4, purlins 10, roof materials 20, 30, and connecting materials 50 constitute the roof body 3 of the roof structural body 1, and are arranged above the installation location G of the roof structural body 1. The roof body 3 extends from the supports 2 toward above the installation location G, and the roof materials 20, 30 located in the ceiling portion cover the installation location G from above. The roof materials 20, 30 include two end roof materials 20 at both ends and multiple intermediate roof materials 30 between the two end roof materials 20. The roof materials 20, 30, including the end roof materials 20, are arranged side by side on the underside of the purlin 10 and are held by the purlin 10. The end roof materials 20 extend from the end 11 of the purlin 10 below, and are arranged above, the end 11 of the purlin 10.

[0019] The connecting material 50 extends outward from the end 11 of the purlin 10 in the longitudinal direction of the purlin 10. The edge roof material 20 is located below the end 11 of the purlin 10 and the connecting material 50, and is arranged to a position spaced apart outward in the longitudinal direction of the purlin 10 from the end 11 of the purlin 10 and the connecting material 50. The edge roof material 20 extends outward in the longitudinal direction of the purlin 10 relative to the end 11 of the purlin 10 and the connecting material 50, and shields the end 11 of the purlin 10 and the connecting material 50 from below.

[0020] When the roof structure 1 and the roof body 3 are viewed from below at the installation location G of the roof structural member 1, the roofing materials 20, 30 are visible, and the purlins 10 and connecting materials 50 are shielded and hidden by the roofing materials 20, 30. The purlins 10 and connecting materials 50 are arranged only in areas vertically above the multiple roofing materials 20, 30 without protruding from areas vertically above the multiple roofing materials 20, 30, and are shielded on their vertically lower sides by the multiple roofing materials 20, 30. In addition, the beams 4 are formed shorter than the roofing materials 20, 30, and are arranged above the intermediate roofing material 30. On the front side in the projection direction of the beams 4, intermediate roofing material 30, and roof body 3 that project from the supports 2, the intermediate roofing material 30 projects from the beams 4 and is arranged to a position farther away from the support 2 than the tips of the beams 4.

[0021] 8 and 9 are diagrams showing roof materials 20, 30 attached to the purlin 10 of the roof structural body 1 of the first embodiment, and show cross sections perpendicular to the longitudinal direction of the purlin 10. As shown in the figure, the purlin 10 has a hollow portion 12 formed in a hollow shape and fin portions 13 protruding from the hollow portion 12. The hollow portion 12 extends in the longitudinal direction of the purlin 10, opens at end portions 11 on both sides of the purlin 10, and opens outward in the longitudinal direction of the purlin 10. The fin portions 13 are located on both sides of the hollow portion 12, sandwiching the hollow portion 12, and extend in the longitudinal direction of the purlin 10. The roof materials 20, 30 are attached to the fin portions 13 and the purlin 10 by screws 41, which are mounting fixtures, and are held in place by the fin portions 13 and the purlin 10.

[0022] Figure 10 is a cross-sectional view showing the purlin 10, connecting material 50, and roof materials 20, 30 of the roof structure 1 of the first embodiment, and shows portions of the purlin 10, connecting material 50, and roof materials 20, 30 shown in Figure 7 separated. As shown in the figure, the connecting material 50 is attached to the end 11 of the purlin 10 by upper and lower screws 42, 43 which serve as fasteners, and is attached to the end 11 of the purlin 10 and the end of the hollow section 12. In addition, the edge roof material 20 is attached to the connecting material 50 by screws 44 which serve as fasteners, and is attached to the end 11 of the purlin 10 by the connecting material 50. In this state, the edge roof material 20 is positioned below the end 11 of the purlin 10 and the connecting material 50, overhanging the end 11 of the purlin 10 and the connecting material 50.

[0023] The roofing materials 20, 30 have retaining portions 21, 31 that are held by the purlin 10. The retaining portions 21, 31 are protrusions (retaining protrusions) located on the upper side of the roofing materials 20, 30, and are formed in a curved shape. The retaining portions 21, 31 protrude upward and are bent laterally at their upper ends. The retaining portion 21 of the end roofing material 20 is located at the edge on one side of the end roofing material 20 in the width direction (the edge located on the end 11 side of the purlin 10), and the retaining portions 31 of the intermediate roofing material 30 are located at each of the edge portions on both sides of the intermediate roofing material 30 in the width direction. The width direction of the roofing materials 20, 30 is the width direction that is perpendicular to the longitudinal direction of the roofing materials 20, 30 and is also perpendicular to the thickness direction of the roofing materials 20, 30.

[0024] The retaining portions 21, 31 of adjacent roofing materials 20, 30 in the parallel direction of the multiple roofing materials 20, 30 are attached to the purlin 10 (fin portions 13) with common screws 41 in a vertically overlapping state and held to the purlin 10 (see Figure 7). The retaining portions 21, 31 of adjacent roofing materials 20, 30 are the retaining portion 21 of adjacent end roofing materials 20 and the retaining portion 31 of adjacent intermediate roofing materials 30, and the retaining portions 31 of adjacent intermediate roofing materials 30. The retaining portion 21 of the end roofing material 20 is positioned overlapping the retaining portion 31 of the intermediate roofing material 30, which is the other roofing material adjacent to the end roofing material 20, and is attached to and held by the purlin 10 together with the retaining portion 31 of the intermediate roofing material 30 with screws 41.

[0025] Figure 11 is a cross-sectional view showing the purlin 10, connecting material 50, and roofing materials 20, 30 of the roof structural body 1 of the first embodiment separated, and shows an enlarged view of the peripheral portion of the end portion 11 of the purlin 10 in the roof structural body 1 shown in Figure 10. Figure 12 is a cross-sectional view showing the purlin 10, connecting material 50, and roofing materials 20, 30 of the roof structural body 1 of the first embodiment, and shows an enlarged view of the peripheral portion of the end portion 11 of the purlin 10 in the roof structural body 1 shown in Figure 7.

[0026] As shown in the figure, after the connecting material 50 is attached to the end 11 of the purlin 10, the end roof material 20 is attached to the connecting material 50 and the purlin 10, and the intermediate roof material 30 is attached to the purlin 10. The connecting material 50 has an attachment portion 51 that is attached to the end 11 of the purlin 10, and an extension portion 52 that extends from the end 11 of the purlin 10. The attachment portion 51 is a cap (small end cap) that is placed at the opening of the hollow portion 12 of the purlin 10, and covers the opening of the hollow portion 12 at the end 11 of the purlin 10.

[0027] The mounting portion 51 of the connecting material 50 is attached to the end portion 11 of the purlin 10 with screws 42, 43, and is attached to the end portion 11 of the purlin 10 and the end portion of the hollow portion 12, closing the opening of the hollow portion 12 at the end portion 11 of the purlin 10. The protruding portion 52 is a protruding piece that protrudes from the mounting portion 51, and protrudes outward in the longitudinal direction of the purlin 10 from the end portion 11 of the purlin 10 and the mounting portion 51. The protruding portion 52 is located above the end roof material 20, and is arranged to a position spaced apart outward in the longitudinal direction of the purlin 10 from the end portion 11 of the purlin 10 and the mounting portion 51.

[0028] The edge roof material 20 has an attachment portion 22 that is attached to the connecting material 50, and a protrusion 23 that protrudes from the attachment portion 22. The attachment portion 22 is a protrusion (attachment protrusion) located on the upper side of the edge roof material 20, and is formed in a curved shape. The attachment portion 22 protrudes upward and is bent laterally at the upper end. The attachment portion 22 is located in the middle of the edge roof material 20 in the width direction, and is also located between the edge on one side and the edge on the other side of the edge roof material 20 in the width direction.

[0029] The mounting portion 22 is placed from above on the overhanging portion 52 (here, the tip of the overhanging portion 52) of the connecting material 50 and hooked onto the overhanging portion 52 from above. In this state, the mounting portion 22 is attached to the overhanging portion 52 with screws 44 and is held in place by the overhanging portion 52 and the connecting material 50. The edge roof material 20 overhangs from the end 11 of the purlin 10, beyond the overhanging portion 52 and mounting portion 22 of the connecting material 50, toward the outside in the longitudinal direction of the purlin 10, below the purlin 10 and the connecting material 50. In this way, the edge roof material 20 overhangs from the end 11 of the purlin 10, and also overhangs from the overhanging portion 52 and mounting portion 22 in the overhanging direction from the end 11 of the purlin 10.

[0030] The retaining portion 21 of the edge roof material 20 is located on the end 11 side of the purlin 10 relative to the mounting portion 22, and is held by the purlin 10. The retaining portion 21 is spaced apart from the mounting portion 22 on the end 11 side of the purlin 10, and the mounting portion 22 is located between the tip of the edge roof material 20 in the projection direction and the retaining portion 21. The projection portion 52 of the connecting member 50 is arranged between the mounting portion 22 of the edge roof material 20 and the end 11 of the purlin 10, and between the mounting portion 22 of the edge roof material 20 and the retaining portion 21.

[0031] The protruding portion 23 of the end roof material 20 is a veneer portion formed in a plate shape, and protrudes from the mounting portion 22 toward the opposite side of the retaining portion 21. The protruding portion 23 is located between the tip of the end roof material 20 in the protruding direction and the mounting portion 22, and is positioned further away from the end 11 of the purlin 10 than the protruding portion 52 and the connecting member 50. The protruding portion 23 protrudes from the mounting portion 22 in the protruding direction of the end roof material 20, and is positioned below the connecting member 50, protruding relative to the protruding portion 52 and the connecting member 50.

[0032] As explained above, in the roof structure 1 of the first embodiment, the roof materials 20, 30 make the beams 4 and purlins 10 difficult to see from below, improving the design of the roof structure 1. In addition, the connecting material 50 makes it possible to stably hold the end roof material 20 to the purlins 10. Because the roof materials 20, 30 are arranged to overhang from the beams 4 and purlins 10, the length of the beams 4 and purlins 10 is such that they are arranged within the area of ​​multiple roof materials 20, 30, which also makes it possible to reduce the cost of the beams 4 and purlins 10.

[0033] By hooking the mounting portion 22 of the edge roof material 20 onto the overhanging portion 52 of the connecting material 50, the edge roof material 20 can be stably attached to the connecting material 50. In addition, the edge roof material 20 overhangs beyond the overhanging portion 52, allowing for a greater overhang of the edge roof material 20 from the end 11 of the purlin 10. The retaining portion 21 and protruding portion 23 of the edge roof material 20 allow the edge roof material 20 to be stably held to the purlin 10 in a state where it overhangs from the end 11 of the purlin 10. The hollow portion 12 ensures the strength of the purlin 10, and by providing the attachment portion 51 on the connecting material 50, the connecting material 50 can be used as a member for closing the opening of the hollow portion 12.

[0034] It is not necessary to provide a hollow portion 12 in the purlins 10, and it is not necessary to provide an attachment portion 51 in the connecting material 50. Also, here, the connecting materials 50 are separately attached to the end portions 11 of multiple purlins 10. Alternatively, one connecting material 50 may be placed across the end portions 11 of multiple purlins 10, and one connecting material 50 may be attached to the end portions 11 of multiple purlins 10. In this case, the connecting material 50 is placed between the end portions 11 of adjacent purlins 10, and the connecting material 50 can shield the area between the end portions 11 of adjacent purlins 10. The purlins 10 may or may not be perpendicular to the beams 4. The roof materials 20, 30 may or may not be perpendicular to the purlins 10.

[0035] The roof structural body 1 requires at least one support column 2, one beam 4, and one purlin 10. However, by providing two or more support columns 2, two or more beams 4, and two or more purlins 10, the roof structural body 1 and the roof body 3 can be installed stably. Also, while the example described here uses support columns 2 as the supports supporting the beams 4 and the roof body 3 of the roof structural body 1, the supports of the roof structural body 1 are not limited to support columns 2 and may be other supports (for example, walls). The present invention is not limited to carports, but can also be applied to various roof structures (for example, cycle ports).

[0036] Next, roof structural members 1 of other embodiments will be described. In the roof structural members 1 of the second to fifth embodiments below, explanation of the same points as those of the roof structural member 1 of the first embodiment will be omitted, and the following mainly describes the points that differ from the roof structural member 1 of the first embodiment. Furthermore, for the roof structural members 1 of the second to fifth embodiments, the same names and symbols as those of the roof structural member 1 of the first embodiment will be used for the components that correspond to those of the roof structural member 1 of the first embodiment.

[0037] (Second embodiment) Figure 13 is a cross-sectional view showing the purlin 10, connecting material 50, and roofing materials 20, 30 of the roof structural body 1 of the second embodiment separated, and similar to Figure 11, shows an enlarged view of the peripheral portion of the end portion 11 of the purlin 10 of the roof structural body 1. Figure 14 is a cross-sectional view showing the purlin 10, connecting material 50, and roofing materials 20, 30 of the roof structural body 1 of the second embodiment, and similar to Figure 12, shows an enlarged view of the peripheral portion of the end portion 11 of the purlin 10 of the roof structural body 1.

[0038] As shown in the figures, in the roof structure 1 of the second embodiment, the connecting material 50 has a hollow portion (reinforcing hollow portion 53) that reinforces the connecting material 50. The reinforcing hollow portion 53 is a reinforcing portion of the connecting material 50, and has a connection portion 53A that connects to the attachment portion 51 and the overhang portion 52.
