Description

The present invention relates to a roof structure in which a roof is supported by pillars installed in a concrete floor.

In roof structures such as carports, pillars are supported by support materials, and multiple pillars are installed on the concrete floor. The roof of the roof structure is also supported by multiple pillars and placed above the concrete floor. In such roof structures, various forces are applied to the pillars, so they must be stably supported by support materials. Therefore, a roof structure and a construction method for a roof structure are known in the art in which support materials are buried in the ground below the concrete floor and the lower ends of the pillars are supported by the support materials (see Patent Document 1).

In the conventional roof structure and roof structure construction method described in Patent Document 1, the support materials and pillars are supported by the weight of the soil, roadbed, and slab concrete that rest on the plate-shaped portions of the support materials. However, in conventional roof structures and roof structure construction methods, the support materials must be buried deep enough to support the pillars, which may increase the workload of roof structure construction, including excavating the ground. Furthermore, the soil removed from the excavation must be disposed of. This increases the time from excavating the ground to pouring the slab concrete, raising concerns that this could extend the construction period for the roof structure.

An embodiment of a roof structure of the present invention will be described with reference to the drawings.
The roof structure of this embodiment is an outdoor structure having a roof and is installed outside a building. The roof structure is installed on a concrete floor independently of the building. Several embodiments of the roof structure will be described below.

(First embodiment)
Fig. 1 is a side view showing a roof structure 1 of the first embodiment, and Fig. 2 is a front view showing the roof structure 1 of the first embodiment as seen from the direction of arrow X1 in Fig. 1. Figs. 1 and 2 schematically show a cross section of the underground area of an installation location 2 of the roof structure 1 and the structure of the underground portion of the roof structure 1. Fig. 3 is a plan view showing the roof structure 1 of the first embodiment as seen from the direction of arrow X2 in Fig. 1.

As shown in the figure, roof structure 1 is installed at installation location 2, which is covered from above. Roof structure 1 includes a concrete slab 3 installed at installation location 2. Concrete slab 3 is the floor of roof structure 1 installed on ground 4 and forms floor surface 3A of roof structure 1. Concrete slab 3 is a flat concrete layer that is poured on top of ground 4 and covers ground 4 from above. Ground 4 is made of, for example, crushed stone laid and compacted on top of the soil ground (not shown) at installation location 2. Reinforcement material (not shown) is embedded inside concrete slab 3 for reinforcement. The reinforcing material of concrete slab 3 is steel bar, which is arranged inside concrete slab 3.

The roof structure 1 is a roof unit installed on the concrete floor 3 at the installation location 2 and is self-supporting at the installation location 2. The roof structure 1 also includes multiple pillars 5 erected on the concrete floor 3, a roof 6 supported by the multiple pillars 5, and multiple support members 7 supporting each of the multiple pillars 5. In this example, the roof structure 1 is a carport, with each pillar 5 supported by two support members 7, and the square-shaped roof 6 supported by the two pillars 5. The roof 6 is a roof body covering the concrete floor 3 at the installation location 2 of the roof structure 1 and is attached to the upper ends of the pillars 5. The roof 6 includes a lattice-shaped roof frame 6A supported by the pillars 5 and multiple plate-shaped roof members 6B that fill the gaps in the roof frame 6A.

The support pillars 5 are installed upright on the concrete floor 3 and protrude upward from the concrete floor 3. The two support pillars 5 are installed at a distance from each other and extend vertically. The two support pillars 5 are also positioned spaced apart from each other in the extension direction of one edge 6C of the four edges 6C, 6D, 6E, and 6F of the roof 6. The edge 6C of the roof 6 is attached to each of the two support pillars 5, and the two support pillars 5 support the edge 6C of the roof 6.

The roof 6 is supported by the two pillars 5 at its edge 6C, projecting from the two pillars 5 in a projection direction H. The projection direction H of the roof 6 is the direction in which the roof 6 projects from the two pillars 5 along the floor surface 3A of the concrete floor 3. The projection direction H of the roof 6 is also the direction from one edge 6C attached to the pillar 5 to the other edge 6D not attached to the pillar 5, of the two opposing edges 6C, 6D of the roof 6. The other edge 6D is the edge at the tip of the projection direction H of the roof 6.

The support members 7 are metal (here, steel) supports (support brackets) that are provided at the installation location 2 of the roof structure 1, at the installation positions of each of the two pillars 5. The two pillars 5 are fixed to different support members 7. The support members 7 are positioned from a position above the lower ends 5A of the pillars 5, through the lower ends 5A of the pillars 5, to a position below the pillars 5, and are held at the installation location 2. The lower ends 5A of the pillars 5 are attached and fixed to the support members 7, and the support members 7 support the lower ends 5A of the pillars 5. Supported by the support members 7, the pillars 5 remain installed on the concrete slab 3, supporting the roof 6 that overhangs in the overhang direction H.

Figure 4 shows the support member 7 of the first embodiment. Figure 4A is a side view of the support member 7, showing one of the support members 7 shown in Figure 1. Figure 4B is a front view of the support member 7 as viewed from the direction of arrow X3 in Figure 4A, showing one of the support members 7 shown in Figure 2. Figure 4C is a plan view of the support member 7 as viewed from the direction of arrow X4 in Figure 4B, showing one of the support members 7 shown in Figure 3.

As shown in the figure, the support material 7 has a rectangular base plate portion 10, a pillar fixing portion 11 fixed to the base plate portion 10, and multiple fixing portions 12 fixed to the base plate portion 10. The base plate portion 10 is a plate-shaped base that supports the support material 7 and is located at the lowest part of the support material 7. When the roof structure 1 is viewed from above (see Figure 3), the base plate portion 10 is formed larger than the pillars 5, and the pillars 5 are positioned within the base plate portion 10. The base plate portion 10 also extends outward from the entire outer periphery of the pillars 5. The pillar fixing portion 11 and fixing portions 12 are each located above the base plate portion 10 and are fixed to the base plate portion 10 by welding.

The support post fixing portion 11 is a cylindrical fixed post that protrudes upward from the base plate portion 10. The support post fixing portion 11 also has multiple screw holes 13 formed at a distance from one another. In the longitudinal direction of the base plate portion 10 (see Figures 4B and 4C), the support post fixing portion 11 is located between an edge portion (first edge portion 14) on one side of the base plate portion 10 in the longitudinal direction and an edge portion (second edge portion 15) on the other side. The first edge portion 14 and the second edge portion 15 are edges that face each other in the longitudinal direction of the base plate portion 10.

In the longitudinal direction of the base plate 10, the support fixing portion 11 is located at a position offset from the center of the base plate 10 (center in the longitudinal direction) toward the first edge 14 of the base plate 10. When comparing the distance (shortest distance) between the support fixing portion 11 and each of the first edge 14 and second edge 15, the distance between the first edge 14 and the support fixing portion 11 is shorter than the distance between the second edge 15 and the support fixing portion 11. The support fixing portion 11 is fixed to the base plate 10 offset from the center in the longitudinal direction of the base plate 10 toward the first edge 14.

The multiple fixing portions 12 surround the support fixing portion 11 and are arranged around the support fixing portion 11. The fixing portions 12 are fixing protrusions that protrude upward from the base plate portion 10 and are arranged at four locations on the base plate portion 10, spaced apart from the support fixing portion 11. The four fixing portions 12 are provided adjacent to the four corners of the base plate portion 10 and spaced apart from each other. Each fixing portion 12 has a screw portion 16 fixed to the base plate portion 10, two nuts 17 movably attached to the screw portion 16, and a fixing plate 18 held between the two nuts 17. The screw portion 16 is a bolt welded to the base plate portion 10 and protrudes upward from the base plate portion 10.

The nut 17 threads onto the male threads (not shown) on the outer periphery of the threaded portion 16 and moves up and down along the threaded portion 16. The fixing plate 18 has an insertion hole (not shown) through which the threaded portion 16 passes, and is sandwiched between and tightened by the two nuts 17. The fixing plate 18 is formed in a rectangular shape and is held to the threaded portion 16 of the fixing portion 12 by the two nuts 17. Furthermore, the vertical position of the fixing plate 18 can be changed by moving the two nuts 17 up and down along the threaded portion 16. In this way, the fixing plate 18 is provided on the fixing portion 12 so that its position in the vertical direction (the direction in which the fixing portion 12 protrudes from the base plate portion 10) can be changed.

Figure 5 shows the support material 7 and support pillar 5 of the first embodiment, showing the support pillar 5 fixed to the support material 7. Figure 5A is a side view of the support material 7 and support pillar 5, showing the support material 7 shown in Figure 4A. Figure 5B is a front view of the support material 7 and support pillar 5 as viewed from the direction of arrow X5 in Figure 5A, showing the support material 7 shown in Figure 4B. Figure 5C is a plan view of the support material 7 and support pillar 5 as viewed from the direction of arrow X6 in Figure 5B, showing the support material 7 shown in Figure 4C. In Figures 5A and 5B, the pillar fixing portion 11 of the support material 7 housed inside the support pillar 5 is shown by a dotted line.

As shown in the figure, the pillar fixing portion 11 of the support material 7 is inserted into the cylindrical pillar 5 from below and placed inside the pillar 5. In this state, the pillar 5 is fixed to the pillar fixing portion 11 with a plurality of bolts 8. The bolts 8 are inserted through insertion holes (not shown) in the pillar 5 from the outside and screwed into the screw holes 13 in the pillar fixing portion 11, thereby attaching the bolts to the pillar fixing portion 11. The pillar 5 surrounds the entire pillar fixing portion 11, housing the entire pillar fixing portion 11 inside. The pillar fixing portion 11 is a holding portion connected to the pillar 5 by the bolts 8, and holds the pillar 5 via the bolts 8.

The roof structure 1 includes an anchoring member 9 attached to the lower end 5A of the support column 5 by a bolt 8. The bolt 8 is inserted from the outside of the support column 5 through an insertion hole (not shown) in the anchoring member 9 and then through an insertion hole (not shown) in the lower end 5A of the support column 5, and is threaded into a threaded hole 13 in the support column fixing portion 11, thereby attaching the bolt to the support column fixing portion 11. The bolt 8 secures the lower end 5A of the support column 5 to the support column fixing portion 11 of the support member 7, and the anchoring member 9 is attached and fixed to the lower end 5A of the support column 5. The anchoring member 9 has a first protrusion 9A and a second protrusion 9B formed integrally with the bolt 8. The first protrusion 9A protrudes outward from the lower end 5A of the support column 5, and the second protrusion 9B protrudes upward from the tip of the first protrusion 9A in the protruding direction. The anchoring member 9 is formed into a curved shape by the first protrusion 9A and the second protrusion 9B.

The fixing members 9 are protruding members that protrude outward from the lower end 5A of the support 5, and are attached to the lower end 5A of the support 5 at two locations. The two fixing members 9 protrude outward from the support 5 in opposite directions from two locations facing opposite sides of the lower end 5A of the support 5. Furthermore, of the two fixing members 9, one fixing member 9 protrudes from the lower end 5A of the support 5 in the overhang direction H of the roof 6 (see Figure 2), and the other fixing member 9 protrudes from the lower end 5A of the support 5 in the opposite direction to the overhang direction H of the roof 6.

FIG. 6 is a diagram showing the construction procedure for the roof structural body 1 of the first embodiment, and similar to FIG. 2 , shows the roof structural body 1 and a cross section of the underground of the installation location 2 of the roof structural body 1.
As shown in the figure, when constructing the roof structural body 1, the base plate portion 10 of the support member 7 is placed on the ground 4 at each location where the two support members 7 are to be installed (see FIG. 6A). A recess 4A is formed in advance in the ground 4 at the location where the base plate portion 10 will be placed. The recess 4A is a depression with a depth corresponding to the thickness of the base plate portion 10. The base plate portion 10 is placed on the recess 4A in the ground 4 from above, and part or all of the thickness direction (vertical direction) of the base plate portion 10 is positioned within the recess 4A.

Next, for each of the two support members 7, the support posts 5 are fixed to the support post fixing portions 11 of the support members 7 that protrude from the base plate portions 10 (see Figure 6B). At this time, the lower ends 5A of the support members 5 are fixed to the support post fixing portions 11, and the anchoring materials 9 are attached to the lower ends 5A of the support members 5. Next, the concrete floor 3 is poured on top of the ground 4 and the base plate portions 10 of the support members 7, and the base plate portions 10 are buried between the ground 4 and the concrete floor 3 (see Figure 6C). In this way, the base plate portion 10 is sandwiched between the ground 4 and the concrete floor 3 and buried in the installation location 2 of the roof structure 1.

The base plate 10 is placed on the upper surface of the ground 4 and is sandwiched between the upper surface of the ground 4 and the lower surface of the concrete floor 3, and is buried between the upper surface of the ground 4 and the lower surface of the concrete floor 3. The lower end 5A of the support 5 and the lower portion 11A of the support fixing portion 11 are located below the floor surface 3A of the concrete floor 3, while the portion above the lower end 5A of the support 5 and the upper portion 11B of the support fixing portion 11 are located above the floor surface 3A of the concrete floor 3.

With the lower end 5A of the support 5 fixed to the support fixing portion 11, the concrete floor 3 is poured on top of the ground 4 and the base plate portion 10 of the support material 7. Accordingly, the lower end 5A of the support 5 is embedded in the concrete floor 3 together with the base plate portion 10 above the base plate portion 10. At the same time, the multiple anchoring portions 12 of the support material 7 protruding from the base plate portion 10 and the multiple anchoring materials 9 protruding from the lower end 5A of the support 5 are anchored to the concrete floor 3. The anchoring portions 12 and anchoring materials 9 are each embedded in the poured concrete floor 3 above the base plate portion 10, embedded in the concrete floor 3, and anchored to the concrete floor 3. As a result, the anchoring portions 12 and anchoring materials 9 are held in place by the concrete floor 3.

The entire anchoring portion 12 and the entire anchoring material 9 are each placed between the base plate portion 10 and the floor surface 3A of the concrete floor 3, and are embedded within the concrete floor 3. The position of the anchoring plate 18 of the anchoring portion 12 can be changed in the vertical direction (thickness direction of the concrete floor 3) to correspond to the thickness of the concrete floor 3. By changing the position of the anchoring plate 18 in the vertical direction, the anchoring plate 18 can be positioned at any position in the thickness direction of the concrete floor 3. In this way, the anchoring plate 18 is embedded at a predetermined position in the thickness direction of the concrete floor 3. The roof 6 is then attached to the two supports 5, and the roof 6 is supported by the two supports 5.

In the first embodiment described above, there is no need to excavate the ground at the installation location 2 of the roof structure 1 when constructing the roof structure 1, which reduces the effort and workload required to construct the roof structure 1 and improves the efficiency of constructing the roof structure 1. In addition, the construction period for the roof structure 1 can be shortened, and the amount of soil removal required for excavating the ground can be reduced. Therefore, the workability of constructing the roof structure 1, which is installed on the concrete slab 3, can be improved.

The base plate portion 10 of the support material 7 is buried between the ground 4 and the concrete slab 3, allowing the support material 7 to be held in place by the ground 4 and the concrete slab 3. Furthermore, various forces acting on the support material 7 from the support posts 5 can be borne by the ground 4 and the concrete slab 3 via the base plate portion 10. Therefore, the support material 7 can be supported by the ground 4 and the concrete slab 3, and the support posts 5 can be stably supported by the support material 7.

The anchoring portion 12 of the support material 7 increases the anchoring strength of the support material 7 to the concrete floor 3. This allows the support material 7 to be firmly fixed to the concrete floor 3, and the concrete floor 3 can stably support the support material 7. By embedding the lower end 5A of the support post 5 in the concrete floor 3, the lower end 5A of the support post 5 can be anchored to the concrete floor 3 while being fixed to the support post fixing portion 11 of the support material 7. Therefore, the lower end 5A of the support post 5 can be supported by the concrete floor 3. By anchoring the anchoring material 9 protruding from the lower end 5A of the support post 5 to the concrete floor 3, the anchoring strength of the lower end 5A of the support post 5 to the concrete floor 3 can be increased. Therefore, the concrete floor 3 can stably support the lower end 5A of the support post 5.

When installing the posts 5 near the periphery of the installation location 2 of the roof structure 1, it is possible that the base plate portion 10 of the support material 7 may extend beyond the periphery of the installation location 2. In this case, the post fixing portion 11 of the support material 7 is positioned offset from the center of the base plate portion 10 toward the first edge portion 14, and the first edge portion 14 of the base plate portion 10 is positioned toward the periphery of the installation location 2. This allows the base plate portion 10 to be positioned inside the installation location 2, while the post fixing portion 11 and the posts 5 fixed to the post fixing portion 11 can be positioned near the periphery of the installation location 2. Furthermore, the roof structure 1 can be easily installed at the installation location 2 even when the installation location 2 is close to the boundary with a neighboring property.

The roof 6 may be supported by one or more pillars 5. One or more anchoring portions 12 may be provided on the support material 7, and one or more anchoring members 9 may be provided on the lower end 5A of the pillar 5. The anchoring plate 18 of the anchoring portion 12 may be provided on the anchoring portion 12 without using the screw portion 16 and nut 17, or may be provided on the anchoring portion 12 so that its vertical position cannot be changed. The anchoring member 9 is not limited to a curved shape and can be formed in various shapes (e.g., L-shaped, plate-shaped). The anchoring member 9 may be provided at only one of two opposite locations on the lower end 5A of the pillar 5, or the anchoring member 9 may not be provided at the lower end 5A of the pillar 5.

The base plate portion 10 of the support material 7 can be formed into various shapes (e.g., square, rectangular, polygonal, circular, elongated). The support post fixing portion 11 of the support material 7 may be provided in the center of the base plate portion 10. The base plate portion 10 of the support material 7 may be placed on flat ground 4 without forming a recess 4A in the ground 4. The present invention is not limited to carports and can be applied to roof structures other than carports (e.g., cycle ports, terraces, sunrooms), and can also be applied to roof structures attached to the wall of a building or to structures other than roofs.

Next, other embodiments of the roof structure 1 will be described. In each of the following embodiments, explanations of the same aspects as in the first embodiment will be omitted, and differences from the first embodiment will be mainly described. Furthermore, in each of the following embodiments, components that correspond to those in the first embodiment will be given the same names as those in the first embodiment.

Fig. 7 is a side view showing the roof structure 1 of the second embodiment, and Fig. 8 is a front view showing the roof structure 1 of the second embodiment as seen from the direction of arrow X7 in Fig. 7. Figs. 7 and 8 schematically show a cross section of the underground area of the installation location 2 of the roof structure 1 and the structure of the underground portion of the roof structure 1. Fig. 9 is a plan view showing the roof structure 1 of the second embodiment as seen from the direction of arrow X8 in Fig. 7.

As shown in the figure, the roof structure 1 of the second embodiment supports a column 5 with each of the four support members 7, and the roof 6 is supported by the four columns 5. The roof 6 is also supported by the four columns 5 at two opposing edges 6C, 6D. Each of the edges 6C, 6D is attached to two columns 5 and supported by two columns 5. At each of the edges 6C, 6D, the two columns 5 are positioned spaced apart from each other in the extension direction of the edges 6C, 6D. In this way, multiple edges of the roof 6 may be supported by the columns 5.

(Third embodiment)
Fig. 10 is a side view showing the roof structure 1 of the third embodiment, and Fig. 11 is a front view showing the roof structure 1 of the third embodiment as seen from the direction of arrow X9 in Fig. 10. Figs. 10 and 11 schematically show a cross section of the underground area of the installation location 2 of the roof structure 1 and the structure of the underground portion of the roof structure 1. Fig. 12 is a plan view showing the roof structure 1 of the third embodiment as seen from the direction of arrow X10 in Fig. 10.

As shown in the figure, the roof structure 1 of the third embodiment, like the roof structure 1 of the first embodiment, supports a pillar 5 with each of two support members 7, and the roof 6 is supported by the two pillars 5. The two pillars 5 are positioned apart from each other in the extension direction of one edge 6C of the roof 6. The edge 6C of the roof 6 is attached to each of the two pillars 5, and the two pillars 5 support the edge 6C of the roof 6. The roof 6 is supported by the two pillars 5 at the edge 6C, overhanging from the two pillars 5 in the overhang direction H.

The support member 7 has a long base plate portion 10 that extends along the upper surface of the ground 4 and the underside of the concrete slab 3. The base plate portion 10 extends and protrudes from the lower end portion 5A of the support column 5 in the protruding direction H of the roof 6. The base plate portions 10 of the two support members 7 are arranged parallel to and spaced apart from each other in a direction intersecting (here, perpendicular to) the protruding direction H of the roof 6. The base plate portion 10 is positioned below the roof 6 between two opposing edges 6C, 6D of the roof 6, and extends along the protruding direction H of the roof 6.

The fixing portions 12 are provided at multiple locations along the length of the base plate portion 10, between one end and the other end of the base plate portion 10 in the longitudinal direction. Here, five fixing portions 12 are arranged at intervals along the length of the base plate portion 10. Furthermore, fixing portions 12 are arranged on both sides of the support fixing portion 11 along the length of the base plate portion 10. Four fixing portions 12 are provided on the portion of the base plate portion 10 below the roof 6, and one fixing portion 12 is provided on the portion of the base plate portion 10 outside the roof 6.

When constructing the roof structure 1, the base plate portion 10 is placed on the ground 4 with its longitudinal direction facing the overhang direction H of the roof 6. Next, the pillars 5 are fixed to the pillar fixing portions 11 of the support members 7. Next, all or part of the roof 6 is attached to the two pillars 5, and the two pillars 5 are connected by all or part of the roof 6. The part of the roof 6 attached to the pillars 5 is all or part of the roof frame 6A of the roof 6. The roof structure 1 is temporarily placed on the ground 4 using the long base plate portion 10, and the concrete slab 3 is poured. Then, if the entire roof frame 6A is attached to the pillars 5, the roof material 6B is attached to the roof frame 6A. If only part of the roof frame 6A is attached to the pillars 5, the roof frame 6A is assembled and the roof material 6B is attached to the roof frame 6A. In this way, the roof 6 is attached to the two supports 5 and supported by the supports 5 while overhanging from the two supports 5 in the overhang direction H. In the third embodiment, the base plate portion 10 of the support member 7 provides stable support for the supports 5 and improves the workability of constructing the roof structure 1.

(Fourth embodiment)
Fig. 13 is a side view showing the roof structure 1 of the fourth embodiment, and Fig. 14 is a front view showing the roof structure 1 of the fourth embodiment as seen from the direction of arrow X11 in Fig. 13. Figs. 13 and 14 schematically show a cross section of the underground portion of the installation location 2 of the roof structure 1 and the structure of the underground portion of the roof structure 1. Fig. 15 is a plan view showing the roof structure 1 of the fourth embodiment as seen from the direction of arrow X12 in Fig. 13.

As shown in the figure, the roof structure 1 of the fourth embodiment, like the roof structure 1 of the second embodiment, supports the roof 6 with four support columns 5. The roof 6 is also supported by four support columns 5 at two opposing edge portions 6C, 6D. Each of the edge portions 6C, 6D is attached to two support columns 5 and supported by two support columns 5. At each of the edge portions 6C, 6D, the two support columns 5 are positioned spaced apart from each other in the extension direction of the edge portions 6C, 6D.

Here, two posts 5 are installed at a distance from each other on each of the opposing edges 6C, 6D of the roof 6, and one support member 7 supports the two posts 5. The support member 7 has a long base plate portion 10 that extends along the upper surface of the ground 4 and the lower surface of the concrete floor 3. The base plate portion 10 is positioned across the two posts 5 and extends between the lower ends 5A of the two posts 5. The post fixing portions 11 of the support member 7 are provided at two locations along the length of the base plate portion 10, and the posts 5 are fixed to each of the two post fixing portions 11 spaced apart along the length of the base plate portion 10.

The lower portion 11A of the pillar fixing portion 11 is an embedded portion that is embedded in the concrete floor 3, and the upper portion 11B of the pillar fixing portion 11 is a protruding portion that protrudes from the concrete floor 3. The lower portion 11A is the portion of the pillar fixing portion 11 on the base plate portion 10 side (lower side), includes the lower end of the pillar fixing portion 11, and is connected to the base plate portion 10. The upper portion 11B is the portion above the lower portion 11A of the pillar fixing portion 11, includes the upper end of the pillar fixing portion 11, and protrudes upward from the floor surface 3A of the concrete floor 3.

The fixing material 9 is attached to the lower portion 11A of the pillar fixing part 11, and the first protrusion 9A of the fixing material 9 protrudes outward from the lower portion 11A of the pillar fixing part 11. In this way, the fixing material 9 is a protruding member that protrudes outward from the lower portion 11A of the pillar fixing part 11, and is attached to the lower portion 11A of the pillar fixing part 11 at two points by welding, and is fixed to the lower portion 11A of the pillar fixing part 11.

The two fixing members 9 protrude outward from the pillar fixing portion 11 in opposite directions from two locations on the lower portion 11A of the pillar fixing portion 11 that face opposite each other. Furthermore, of the two fixing members 9, one fixing member 9 protrudes from the lower portion 11A of the pillar fixing portion 11 in the overhanging direction H of the roof 6 (see Figure 19), and the other fixing member 9 protrudes from the lower portion 11A of the pillar fixing portion 11 in the opposite direction to the overhanging direction H of the roof 6.

When constructing the roof structure 1, the base plate 10 of the support member 7 is placed on the ground 4 (see Figure 21A). Next, without fastening the support columns 5 to the support column fixing portions 11, the concrete floor 3 is poured on top of the ground 4 and the base plate 10 of the support member 7, and the base plate 10 is embedded between the ground 4 and the concrete floor 3 (see Figure 21B). At the same time, the lower portion 11A of the support column fixing portion 11 is embedded in the concrete floor 3 together with the base plate 10 above the base plate 10. In addition, multiple anchoring materials 9 protruding from the lower portion 11A of the support column fixing portion 11 are fixed to the concrete floor 3. The anchoring materials 9 are embedded in the poured concrete floor 3 above the base plate 10, and are embedded in and fixed to the concrete floor 3. As a result, the lower portion 11A of the support post fixing portion 11 and the anchoring material 9 are held in place by the concrete floor 3.

The upper portion 11B of the pillar fixing portion 11 is not embedded in the concrete floor 3, but protrudes upward from it. The pillar 5 is fixed to the upper portion 11B of the pillar fixing portion 11 that protrudes from the concrete floor 3 (see Figure 21C). The upper portion 11B of the pillar fixing portion 11 is inserted into the pillar 5 from below and positioned inside the pillar 5. In this state, the pillar 5 is fixed to the upper portion 11B of the pillar fixing portion 11 using multiple bolts 8. The lower portion 11A of the pillar fixing portion 11 is located below the floor surface 3A of the concrete floor 3, and the pillar 5 and the upper portion 11B of the pillar fixing portion 11 are located above the floor surface 3A of the concrete floor 3. The roof 6 is then attached to the two pillars 5, and the roof 6 is supported by the two pillars 5.

In the sixth embodiment, the lower portion 11A of the support fixing portion 11 can be fixed to the concrete floor 3 by embedding the lower portion 11A of the support fixing portion 11 in the concrete floor 3. This increases the anchoring strength of the support material 7 to the concrete floor 3. Furthermore, by anchoring the anchoring material 9 to the concrete floor 3, the anchoring strength of the lower portion 11A of the support fixing portion 11 and the support material 7 to the concrete floor 3 can be increased.

One or more fixing materials 9 may be provided on the lower portion 11A of the support post fixing portion 11. Furthermore, fixing materials 9 may be provided on only one of two opposite locations on the lower portion 11A of the support post fixing portion 11, or fixing materials 9 may not be provided on the lower portion 11A of the support post fixing portion 11. The configurations of the support post fixing portion 11, support post 5, and fixing materials 9 of the support member 7 of the first to fifth embodiments may be changed to the configurations of the support post fixing portion 11, support post 5, and fixing materials 9 of the support member 7 of the sixth embodiment.
