Description

The present invention relates to outdoor structures equipped with roofing materials, such as carports and terraces.

The roofing materials of outdoor structures are sometimes surrounded by frames. The frames ensure the strength of the roofing materials and also provide a pleasing appearance from a design perspective. The ends of the frames are sometimes connected together with cap-shaped connectors.

Roofing materials are generally formed in a rectangular shape when viewed from above. However, when installing in an irregularly shaped installation space, or when the installation space is rectangular but there are restrictions such as a structure being placed above it or trees growing there, part of the roofing material may be cut at an angle (see, for example, Patent Document 1).

JP 2016-160604 A

It is desirable for frame materials such as those described above to have a waterproofing effect that prevents rainwater from flowing into the lower part of the roof material. A specified sealant can be used to seal between the individual frame materials and the roof material. Furthermore, where frame materials intersect at 90 degrees, angle-fixing connectors with waterproofing properties can be used.

However, when a portion of the roofing material is cut at an angle, as described above, the angle of the cut slanted edge varies depending on the construction conditions, and angle-fixed connectors cannot be used at the end of the slanted edge. Therefore, connectors in such locations must be able to both adjust the angle and provide waterproofing.

The present invention was made in consideration of the above-mentioned problems, and aims to provide an outdoor structure in which the frame material surrounding the roofing materials of various shapes provides an optimal waterproofing effect.

In order to solve the above-mentioned problems and achieve the objectives, the outdoor structure of the present invention is an outdoor structure comprising a roofing material with a protruding corner, and a first frame material and a second frame material provided along two edges of the roofing material that border the protruding corner. The outdoor structure comprises a first cap provided at the end of the first frame material on the protruding corner side, and a second cap provided at the end of the second frame material on the protruding corner side. The first cap comprises a first frame surface cover that covers the end of the first frame material from the top to the side, and an outer cap that protrudes from the first frame surface cover toward the second frame material. The roofing material further includes a cover, the second cap including a second frame surface cover that covers the end of the second frame material from the top to the sides, and an inner cover that protrudes from the second frame surface cover toward the first frame material, the outer cover including an outer arc wall that is arc-shaped convex toward the outer periphery when viewed in the direction perpendicular to the surface of the roofing material, and the inner cover including an inner arc wall that is arc-shaped convex toward the outer periphery when viewed in the direction perpendicular to the surface of the roofing material and faces the inner surface of the outer arc wall, and the outer arc wall and inner arc wall are in direct or indirect surface contact with each other.

In the outdoor structure of the present invention, the intersection angle between the first cap and the second cap can be adjusted as desired depending on the width of the overlapping portion between the outer arc wall and the inner arc wall. Furthermore, the outer arc wall and the inner arc wall, which are in surface contact with each other, provide a waterproofing effect between the first cap and the second cap, providing an ideal waterproofing effect for frames surrounding roof materials of various shapes.

Below, an embodiment of an outdoor structure according to the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to this embodiment.

Figure 1 shows an outdoor structure 10 according to an embodiment of the present invention, with (a) viewed from the side frame side and (b) viewed from the front frame side. The outdoor structure 10 is a carport comprising two upright posts 12 erected on one side of a parking space S, two beams 14 extending gradually upward from the upper ends of the posts 12 toward the other side of the parking space S, and a roof 16 attached to the top of the beams 14. The posts 12 are each rectangular pillar-shaped and erected vertically with their respective lower ends buried in the ground. The beams 14 are each rectangular pillar-shaped and extend approximately parallel to each other.

Multiple purlins 18 are fixed to the beams 14 in a direction perpendicular to them. The purlins 18 are hollow, rectangular tubes with lengths greater than the spacing between the beams 14, and are arranged at equal intervals. Multiple rafters 20 are fixed to the purlins 18 and are parallel to the beams 14. The rafters 20 are basically the same length as the beams 14 and are arranged at equal intervals. The roof 16 is supported by the purlins 18 and rafters 20.

The roof 16 is composed of multiple frame members 22 and roofing materials 24 surrounded by the frame members 22. The roofing materials 24 are thin plates. In describing the roof 16, the side closest to the support pillars 12 is referred to as the rear, and the opposite side as the front. The left and right sides are based on the state shown in Figure 2. The beams 14 slope gradually downward toward the rear. The beams 14 and roof 16 may also be horizontal. Two more support pillars 12 may be provided on the front side as well as the rear side.

Figure 2 is a plan view showing the roof 16 of the outdoor structure 10. Note that the roof 16 is slightly inclined based on the beams 14, so strictly speaking, Figure 2 is a view of the roof 16 from a direction perpendicular to the surface of the roofing material 24, but for simplicity, it will be referred to as a "plan view" here. The same applies to the following figures.

The roof material 24 has four rectangular corners, with the front right corner 24a, shown by the imaginary line in Figure 2, cut at an angle. This angled edge is called the inclined edge 24b. The purlins 18 are installed between the left and right ends of the roof material 24, and the rafters 20 are installed between the front and rear ends of the roof material 24. In this embodiment, the right end of the foremost purlin 18 extends to the inclined edge 24b.

The rear corner 24c and front corner 24d of the inclined edge 24b are obtuse-angled corners. The inclined edge 24b is formed due to constraints such as irregular ground shape or other structures or trees, and the inclination angle and length are determined based on the construction site conditions and the client's requests. In this example, the rear corner 24c is located approximately midway between the front and rear of the roof 16, and the angle θ between the inclined edge 24b and the extension of the right edge is approximately 24 degrees.

Five frame members 22 are provided surrounding the roof member 24. These include the rear frame member 26 along the rear edge, the front frame member 28 along the front edge, the left frame member 30 along the left edge, the first right frame member 32A along the right edge, and the second right frame member 32B along the inclined edge 24b. The first right frame member 32A and the second right frame member 32B are provided along the right edge and inclined edge 24b, with the protruding corner 24c as the boundary. The front frame member 28 and the second right frame member 32B are provided along the front edge and inclined edge 24b, with the protruding corner 24d as the boundary. At the protruding corner 24c, the first right frame member 32A and the second right frame member 32B are connected by a connector 34. Similarly, at the protruding corner 24d, the front frame member 28 and the second right frame member 32B are connected by a connector 34. The connector 34 will be described later.

Figure 3 is an exploded perspective view of the frame member 22. As shown in Figure 3, the frame member 22 is composed of a profile member 36 and a plate member 38 attached to the top surface of the profile member 36. The profile member 36, the plate member 38, and the beams 14, purlins 18, and rafters 20 are all extruded profiles formed from a metal such as an aluminum alloy, and each is configured to have a substantially uniform cross-sectional shape along its entire length.

Two parallel protrusions 38a extending longitudinally are provided near the outer edge of the underside of the plate material 38. The profile 36 has a roof material clamping portion 36a facing the plate material 38, a side wall 36b protruding downward from the outer edge of the roof material clamping portion 36a, a sloping wall 36c protruding diagonally downward from the side wall 36b, and a bottom wall 36d protruding inward from the sloping wall 36c. The side wall 36b is slightly inclined downward and inward. The sloping wall 36c is shorter than the side wall 36b, and smoothly connects the side wall 36b and bottom wall 36d, creating a pleasing appearance. The amount of protrusion of the bottom wall 36d is small.

Two parallel engagement pieces 36aa extending longitudinally are provided near the outer periphery of the upper surface of the roofing material clamping portion 36a. Protrusions 38a engage with the engagement pieces 36aa, thereby securing the plate material 38 to the profile 36. A threaded groove 39 is formed between the two engagement pieces 36aa. Opposite pockets 40 are provided near the inner periphery of the lower surface of the plate material 38 and near the inner periphery of the upper surface of the roofing material clamping portion 36a. Sealing material 42 (see Figure 8) is inserted and secured in the pockets 40. The plate material 38 and roofing material clamping portion 36a sandwich and secure the roofing material 24 via the sealing material 42.

Next, the connector 34 will be described.
The connector 34 can connect two frame members 22 at corners of any angle. Therefore, as described above, the connector 34 is provided at the connection between the first right frame member 32A and the second right frame member 32B, and at the connection between the front frame member 28 and the second right frame member 32B. Hereinafter, the first right frame member 32A will be simply referred to as the first frame member 32A, and the second right frame member 32B will be simply referred to as the second frame member 32B. Figure 4 is a perspective view of the first frame member 32A, the second frame member 32B, and the connector 34 connecting them. Figure 5 is a plan view of the first frame member 32A, the second frame member 32B, and the connector 34 connecting them.

As shown in Figures 4 and 5, the connector 34 is composed of a first cap 44A and a second cap 44B. The first cap 44A and the second cap 44B are made of, for example, a resin material. The first cap 44A and the second cap 44B are provided on the ends of the first frame member 32A and the second frame member 32B on the side of the protruding corner 24c. The first frame member 32A is fixed to the purlin 18 near the connector 34 with screws or the like. The second frame member 32B may be fixed to the purlin 18 near the connector 34 via a bracket (not shown). The first frame member 32A and the second frame member 32B do not necessarily have to be fixed to the purlin 18 near the connector 34.

Figure 6 is a perspective view of the first cap 44A viewed from the outer periphery. Figure 7 is a perspective view of the first cap 44A viewed from the inner periphery. As shown in Figures 4 to 7, the first cap 44A includes a first frame surface cover 46A that covers the end of the first frame member 32A from the top surface (i.e., the surface of the plate member 38) to the side wall 36b, the inclined wall 36c, and the bottom wall 36c; an outer cover 48A that protrudes from the first frame surface cover 46A toward the second frame member 32B (forward in this embodiment); and a lower edge piece 49A that protrudes slightly inward from the lower edge.

The first frame surface cover 46A is divided into a flat upper wall 46Aa that covers the plate material 38, and a side wall 46Ab that extends generally downward and covers the side wall 36b and inclined wall 36c. The side wall 46Ab is slightly inclined downward toward the inner periphery so as to fit along the side wall 36b and inclined wall 36c. The outer cover 48A includes an outer arc wall 50A that has an arc shape that convex toward the outer periphery, and an outer upper wall 52A that connects to the upper end of the outer arc wall 50A.

The outer upper wall 52A extends forward from the upper wall 46Aa of the first frame surface cover 46A via a low step. The outer arc wall 50A extends forward from the side wall 46Ab of the first frame surface cover 46A, bulging slightly outward.

The outer arc wall 50A has a fan-shaped arc shape in a plan view, with the center point C of the arc being the point where the front edge of the outer upper wall 52A intersects with the outer arc wall 50A. The outer arc wall 50A has a shape that tapers slightly in diameter downward. Multiple, evenly spaced folding lines 53 are formed on the outer peripheral surface of the outer arc wall 50A in the vertical direction (i.e., the direction perpendicular to the longitudinal direction of the first frame member 32A). In this embodiment, five folding lines 53 are formed.

The first frame surface cover 46A has upper screw holes 54Aa formed in the upper wall 46Aa and lower screw holes 54Ab formed in the side wall 26Ab. The upper screw holes 54Aa are formed in a location facing the threaded groove 39 (see Figure 8). The lower screw holes 54Ab are formed in a location facing the inclined wall 36c.

As shown in FIG. 7, a second water-stopping material 56 is provided on the inner surface of the first frame surface cover 46A. The second water-stopping material 56 is, for example, a sponge material, and is attached to the surface to which it is to be fixed using adhesive or a sticky material. The second water-stopping material 56 is thin and is fixed to almost the entire surface from the top wall 46Aa to the side wall 46Ab.

Figure 8 is a cross-sectional view of the first frame member 32A viewed from the longitudinal direction. As shown in Figure 8, the first cap 44A is fixed to the first frame member 32A with two screws B. One of the screws B is inserted through the upper screw hole 54Aa and threaded into the threading groove 39. The threading groove 39 is open only upward, preventing water from entering the frame space 58 through the upper screw hole 54Aa. The other screw B is inserted through the lower screw hole 54Ab and threaded into a lower hole formed in the inclined wall 36c. Because the inclined wall 36c is shaped to slope inward as it extends downward, the lower screw hole 54Ab and the lower hole are shaped to slope upward as they extend inward, preventing water from entering the frame space 58 through these locations.

The second water-stopping material 56 is compressed between the plate material 38, side wall 36b, and inclined wall 36c and the first frame surface cover 46A, providing a water-stopping effect. This prevents water from entering the frame space 58 from the connection between the first frame material 32A and the first cap 44A. The second water-stopping material 56 is compressed and becomes considerably thinner when the two screws B are fastened, but this is clearly indicated by a thick line in Figure 8. The area where the second water-stopping material 56 is provided is indicated by a light dotted background in Figure 5.

The manner in which the first cap 44A is fixed to the first frame member 32A is unrelated to the second frame member 32B to which it is connected. Therefore, it is possible to fix the first cap 44A to the end of the first frame member 32A in advance at the time of shipment from the factory using a method that also serves as a waterproofing means, such as welding. In this case, it is possible to omit the second waterproofing material 56.

Figure 9 is an oblique view of the second cap 44B from the outer periphery. Figure 10 is an exploded oblique view of the second cap 44B with the first water-sealing material 62 removed. As shown in Figures 4, 5, 9, and 10, the second cap 44B includes a second frame surface cover 46B, an inner cover 48B, and a lower edge piece 49B. The second frame surface cover 46B is symmetrical to the first frame surface cover 46A and covers the end of the second frame member 32B. It has an upper wall 46Ba and a side wall 46Bb. The second frame surface cover 46B has upper screw holes 54Ba and lower screw holes 54Bb at positions corresponding to the upper screw holes 54Aa and lower screw holes 54Ab in the first frame surface cover 46A. The second frame surface cover 46B has a second water-sealing material 56 on its inner surface, similar to the first frame surface cover 46A. The second water-stopping material 56 of the second frame surface cover 46B can be omitted, just like the second water-stopping material of the first frame surface cover 46A. The lower edge piece 49B has a symmetrical shape to the lower edge piece 49A described above.

The inner cover 48B protrudes from the second frame surface cover 46B toward the first frame member 32B (rearward in this embodiment). The inner cover 48B includes an inner arc wall 50B that has a convex arc shape on the outer periphery, and an inner upper wall 52B that connects to the upper end of the inner arc wall 50B.

The inner upper wall 52B extends rearward on the same plane from the upper wall 46Ba of the second frame surface cover 46B. The inner arc wall 50B extends rearward from the side wall 46Bb of the second frame surface cover 46B, slightly inward.

The inner arc wall 50B has a fan-shaped arc shape in plan view, with the center point C of the arc coinciding with the center of the outer arc wall 50A in plan view. The inner arc wall 50B has a shape that tapers slightly downward. A low, band-shaped sloped protrusion 60 is formed at the boundary with the inner cover 48B, extending from the top wall 46Ba to the side wall 46Bb. The sloped protrusion 60 has a height of 0 at its front end and gradually increases in height from front to rear. The protruding height of the rear end of the sloped protrusion 60 is approximately equal to the sum of the thickness of the outer cover 48A and the compressed thickness of the first water-stopping material 62, described below.

A first water-stopping material 62 is provided on the outer surface of the inner arc wall 50B. The first water-stopping material 62 is, for example, a sponge material similar to the second water-stopping material 56, and is attached to the target surface using adhesive or a sticky material. The first water-stopping material 62 is thin and is fixed to almost the entire surface from the inner upper wall 52B to the inner arc wall 50B. However, the first water-stopping material 62 is not provided on the lowest inwardly sloping portion of the inner arc wall 50B. This is because the area is small and it has little effect on the water-stopping function against rainwater trickling down from above. In other words, the first water-stopping material 62 only needs to be provided on the top surface and in an area that is essentially considered a side wall, and does not need to be provided on surfaces that slope inward at an angle greater than a certain degree. The same applies to the second water-stopping material 56.

The first water-sealing material 62 may also be provided on the inner surface of the outer arc wall 50A. In other words, the first water-sealing material 62 may be provided so as to be interposed between the outer arc wall 50A and the inner arc wall 50B. In Figure 5, the area where the first water-sealing material 62 is provided is indicated by dark dots. Note that the manner in which the second cap 44B is fixed to the second frame member 32B is similar to the manner in which the first cap 44A is fixed to the first frame member 32A (see Figure 8), and therefore is not illustrated or described here.

Returning to Figures 4 and 5, the first cap 44A and the second cap 44B overlap at the outer cover 48A and inner cover 48B. In other words, the outer upper wall 52A covers the top of the inner upper wall 52B, and the outer arc wall 50A covers the sides of the inner arc wall 50B. A first water-stopping material 62 is interposed in an appropriately compressed state between the inner upper wall 52B and the outer upper wall 52A, and between the inner arc wall 50B and the outer arc wall 50A, providing a water-stopping effect between the first cap 44A and the second cap 44B.

The first water-stopping material 62 is compressed by the surfaces between the outer upper wall 52A and the inner upper wall 52B, and between the outer arc wall 50A and the inner arc wall 50B, ensuring an appropriate water-stopping width along the direction of rainwater infiltration (in this case, the front-to-back direction), resulting in an optimal water-stopping effect. Furthermore, the first water-stopping material 62 has a long lifespan because it is not locally excessively compressed by the surfaces being compressed.

In the connector described in Patent Document 1, the frame material must be cut diagonally to match the intersection angle, and additional connecting aids must be provided at the diagonal edges. In contrast, in this embodiment, the edges of the first frame material 32A and the second frame material 32B do not need to be cut at an angle, and can be right angles regardless of the intersection angle. Furthermore, no connecting aids other than the first cap 44A and the second cap 44B are required.

In this embodiment, the provision of the first water-stopping material 62 between the outer arc-shaped wall 50A and the inner arc-shaped wall 50B provides an optimal water-stopping effect, but the first water-stopping material 62 may be omitted depending on design conditions. For example, if either the outer arc-shaped wall 50A or the inner arc-shaped wall 50B is formed from a rubber material, the rubber material itself has a water-stopping effect, so the first water-stopping material 62 need not be provided. In other words, the outer arc-shaped wall 50A and the inner arc-shaped wall 50B may be configured to be in direct surface contact, or indirect surface contact via the first water-stopping material 62. The same applies to the area between the outer upper wall 52A and the inner upper wall 52B.

Furthermore, since the outer arc wall 50A and the inner arc wall 50B have concentric arc surfaces based on the center point C, the first cap 44A and the second cap 44B can be set at any angle based on the center point C.

If the length of the outer arc wall 50A along the arc is excessive due to the angle between the first cap 44A and the second cap 44B, a desirable appearance can be achieved by breaking or cutting off the multiple break lines 53 at appropriate locations. This breaking or cutting can be easily done by hand or with a tool such as a blade. In the example shown in Figure 4, the five break lines 53 shown in Figure 6 have been broken off at their centers.

The inner arc wall 50B and first water-stopping material 62 are virtually invisible because they are mostly covered by the outer arc wall 50A. Furthermore, the edge of the broken-off outer arc wall 50A faces the edge of the sloped protrusion 60 via a narrow gap, forming a continuous curved surface from the outer arc wall 50A to the sloped protrusion 60, resulting in a pleasing appearance.

In this way, the connector 34 can connect the first frame member 32A and the second frame member 32B at any intersection angle, and the outer arc wall 50A and the inner arc wall 50B provide a waterproof seal between the first cap 44A and the second cap 44B, allowing the frame member 22 surrounding roof members 24 of various shapes to achieve optimal waterproofing.

Figure 11 is a plan view showing the connector 34 applied to a location where the first frame member 32A and the second frame member 32B are arranged in a straight line. The connector 34 is basically applied to locations with an angle, but it is also possible to connect the first frame member 32A and the second frame member 32B in a straight line, as shown in Figure 11. Of course, it can also be applied when the first frame member 32A and the second frame member 32B intersect at a small angle.

Figure 12 is a plan view showing a modified connector 70. In connector 70, parts corresponding to those in connector 34 described above are given the same reference numerals. Connector 70 can be used where the first frame member 32A and the second frame member 32B intersect at a relatively large angle (90 degrees in Figure 12).

In the connector 70, the first frame surface cover 46A and the second frame surface cover 46B protrude relatively far, and the first frame member 32A and the second frame member 32B fixed thereto are positioned slightly away from the center point C. This prevents interference even when the intersection angle is relatively large. Furthermore, in the connector 70, the inner arc-shaped wall 50B and the inner upper wall 52B are shaped to accommodate the relatively large intersection angle between the first frame member 32A and the second frame member 32B. Specifically, in this case, the inner arc-shaped wall 50B and the inner upper wall 52B cover a range of 90 degrees or more relative to the center point C. In Figure 12, the outer arc-shaped wall 50A is illustrated in the same manner as the connector 34 described above, but the outer arc-shaped wall 50A may also be shaped to an angle of 90 degrees or more in accordance with the inner arc-shaped wall 50B. In this case, it is recommended to provide multiple break creases 53 in accordance with the area of the outer arc-shaped wall 50A. The connector 70 can also be used when the intersection angle between the first frame member 32A and the second frame member 32B is small.

Figure 13 is a plan view of a roof 16A according to a first modified example. The roof material 24 of the roof 16A has a rectangular shape with the rear right corner in Figure 13 cut at an angle. In this case, the first frame material 32A is provided along the inclined edge 24b, and the second frame material 32B is provided along the right edge. A protruding corner 24e is formed between the inclined edge 24b and the right edge, and a protruding corner 24f is formed between the inclined edge 24b and the rear frame material 26. The inclined edge 24b of the roof 16A is relatively short, and the protruding corner 24e is located at a position that approximately intersects with the purlin 18 closest to the rear. The connector 34 can also be used on these protruding corners 24e, 24f.

Figure 14 is a plan view of a roof 16B according to a second modified example. Figure 15 is a plan view of a roof 16C according to a third modified example. In roofs 16B and 16C, an auxiliary frame member 72 is provided between the first right frame member 32A and the second right frame member 32B. The first right frame member 32A and the second right frame member 32B extend in the front-to-rear direction, and the auxiliary frame member 72 extends in the left-to-right direction. The auxiliary frame member 72 in roof 16B is provided in a position extending the central purlin 18, while the auxiliary frame member 72 in roof 16C is provided in a position extending the rearmost purlin 18. In these roofs 16B and 16C, the protruding corner 24g formed by the first right frame member 32A and the auxiliary frame member 72 and the protruding corner 24h formed by the second right frame member 32A and the front frame member 28 are right angles. The above-described connector 70 can be applied to the protruding corners 24g and 24h.

Note that Figures 2, 13, 14, and 15 show examples in which the corner sections 24c to 24h are formed on the right side of the roof 16, but if these corner sections are provided on the left side of the roof 16, they can be applied by simply changing the orientation of the connectors 34 and 70 by 180 degrees.

The present invention is not limited to the above-described embodiments, and can of course be freely modified without departing from the spirit of the present invention.

The outdoor structure of the present invention is an outdoor structure comprising a roofing material with a protruding corner, and a first frame material and a second frame material provided along two edges of the roofing material that border the protruding corner. The structure has a first cap provided at the end of the first frame material on the protruding corner side, and a second cap provided at the end of the second frame material on the protruding corner side. The first cap has a first frame surface cover that covers the end of the first frame material from the top to the side, and an outer cover that protrudes from the first frame surface cover toward the second frame material. The cap comprises a second frame surface cover that covers the end of the second frame material from the top to the sides, and an inner cover that protrudes from the second frame surface cover toward the first frame material, the outer cover comprising an outer arc wall that is arc-shaped convexly outward when viewed in the direction perpendicular to the surface of the roof material, the inner cover comprising an inner arc wall that is arc-shaped convexly outward when viewed in the direction perpendicular to the surface of the roof material and faces the inner surface of the outer arc wall, and the outer arc wall and inner arc wall are in direct or indirect surface contact with each other.

By making the outer arc wall and inner arc wall concentric arc surfaces based on a predetermined center point, the first cap and second cap can be set at any angle based on that center point. Furthermore, the outer arc wall and inner arc wall provide a waterproofing effect on the sides between the first cap and second cap, providing an ideal waterproofing effect for frames surrounding roofing materials of various shapes.

In the outdoor structure of the present invention, the outer arc wall and the inner arc wall may be in surface contact via a first water-stopping material. The first water-stopping material provides an additional waterproofing effect between the outer arc wall and the inner arc wall.

In the outdoor structure of the present invention, the outer cover includes an outer upper wall extending from the upper wall of the first frame surface cover and having an outer peripheral end connected to the upper end of the outer arc wall; the inner cover includes an inner upper wall extending from the upper wall of the second frame surface cover and having an outer peripheral end connected to the upper end of the inner arc wall and facing the inner surface of the outer upper wall; and the first water-stopping material may extend between the outer upper wall and the inner upper wall. This provides a water-stopping effect for the portion of the upper wall between the first cap and the second cap.

The outdoor structure of the present invention may include a second water-stopping material between the first frame surface cover and the first frame member, and between the second frame surface cover and the second frame member. The second water-stopping material provides an additional waterproofing effect for the upper wall portion between the first cap and the second cap.

In the outdoor structure of the present invention, the outer peripheral surface of the outer arc wall may have multiple break lines formed along a direction perpendicular to the longitudinal direction of the first frame member. By breaking off the outer arc wall at appropriate break lines depending on the intersection angle between the first frame member and the second frame member, a desirable appearance can be achieved.

In the outdoor structure of the present invention, the first frame member and the second frame member each have a shaped member and a plate member attached to the top surface of the shaped member and sandwiching the roof material between the shaped member and the plate member; the underside of the plate member has two parallel protrusions extending longitudinally, and the top surface of the shaped member has two parallel engaging pieces extending longitudinally that engage with the two protrusions; screw holes are formed in the top walls of the first frame surface cover and the second frame surface cover; and the first cap and the second cap are secured by inserting screws through the screw holes and threading them between the two engaging pieces. This allows the plate member to be secured with screws without drilling holes in the shaped member.

In the outdoor structure of the present invention, the roofing material has a rectangular shape with at least one of the four corners cut diagonally, and the protruding corner may be a portion formed at the end of the diagonally cut sloping edge of the roofing material.
