[0008] A roof structure including a roof body 2 according to the present disclosure will be described below with reference to the drawings. In this embodiment, an example in which the roof structure is applied to a terrace 1 will be described. Note that, for example, the roof structure may also be applied to structures other than terraces, such as carports, bicycle parking spaces, shelters, rest areas, bus stops, and the like.

[0009] In the description of this embodiment, the wall 10a side of the building 10 in the terrace 1 is referred to as the rear side, and the side of the pillar 11 opposite the wall 10a of the building 10 is referred to as the front side. The direction in which the rafter hanger 3 and the front frame 4 extend is referred to as the left-right direction.

[0010] As shown in FIG. 1, the terrace 1 of this embodiment includes a roof body 2 and two supports 11. The rear side of the roof body 2 is connected to the wall 10a of the building 10, and the front end of the roof body 2 is supported by the two supports 11. The roof body 2 includes a rafter hanger 3 (rear member) fixed to the wall 10a of the building 10, a front frame 4 (front member) arranged at a distance from the rafter hanger 3 to the opposite side of the wall 10a of the building 10, a plurality of rafters 5 extending between the rafter hanger 3 and the front frame 4 and arranged side by side in the left-right direction, a plurality of rafters 6 extending between adjacent rafters 5, and a plurality of panel members 7 attached between adjacent rafters 5 above the rafters 6 and arranged side by side in the left-right direction. The roof body 2 is inclined downward from the rafter hanger 3 side toward the front frame 4 side.

[0011] 1, the multiple rafters 5 include two end rafters 501 (rafters) arranged at both ends of the roof body 2 in the left-right direction, and multiple intermediate rafters 502 (rafters) arranged side by side in the left-right direction (a direction intersecting the direction in which the rafters 5 extend) between the two end rafters 501. The end rafters 501 clamp and fix the widthwise end of the panel material 7 in the up-down direction on one side of the end rafters 501 in the left-right direction (the inner side of the roof body 2 in the left-right direction). The intermediate rafters 502 clamp and fix the widthwise end of the panel material 7 in the up-down direction on both left-right sides of the intermediate rafters 502.

[0012] As shown in Figure 2, the rafter 5 has a rafter body 51 and a rafter cover 52 (rafter upper member) that is positioned on the upper part of the rafter body 51 and sandwiches the end of the panel material 7 between the rafter body 51 and the rafter cover 52 (rafter upper member).

[0013] 2 to 6, the rafter body 51 has a rafter body hollow portion 511 having a hollow portion, and a pair of lower lateral extension portions 515 extending outwardly on both sides at the lower portion of the rafter body hollow portion 511. A plurality of side openings 513 are formed in the rafter side panel 512 of the rafter body hollow portion 511 midway along the longitudinal direction of the rafter 5, corresponding to the positions where a plurality of joists 6 are attached.

[0014] The side opening 513 is formed by penetrating a rafter side panel 512 formed at an end in the width direction of the rafter main body 51. In the end rafter 501 (see FIG. 1), the side opening 513 opens laterally on one side in the width direction of the rafter main body 51, that is, inside in the left-right direction of the roof body 2, and in the intermediate rafter 502 (see FIG. 1), the side opening 513 opens laterally on both sides in the width direction of the rafter main body 51. In this embodiment, the side opening 513 opens, for example, in a rectangular shape.

[0015] As shown in Figs. 3 to 6, the pair of lower lateral extensions 515 has a horizontal extension plate 516 and a protruding plate 517 protruding upward from the outer end of the horizontal extension plate 516. A notch regulating portion 517a (regulating portion) is formed at the position where the siding 6 is attached to the protruding plate 517. When the siding 6 is placed on the lower lateral extension portion 515 of the rafter body 51, the lower regulating protrusion 624 of the siding engagement member 62 (described later) of the siding 6 is placed in the notch regulating portion 517a. As a result, the notch regulating portion 517a regulates the movement of the siding 6 in the longitudinal direction of the rafter 5 by regulating the movement of the lower regulating protrusion 624 of the siding engagement member 62 of the siding 6 in the front-rear direction.

[0016] The plurality of sidings 6 are attached to the rafters 5. As shown in Fig. 6, each of the plurality of sidings 6 has an elongated siding body 61 and a pair of siding engaging members 62 (engagement members) provided at the ends of the siding body 61 in the longitudinal direction X.

[0017] As shown in Fig. 7, the furring strip body 61 has a furring strip body hollow portion 611 having a hollow portion. The furring strip body hollow portion 611 has a small opening 615 that opens at the end face of the furring strip 6 in the longitudinal direction X. The furring strip body hollow portion 611 has a pair of furring strip body side panels 612 and a bottom panel 613.

[0018] The pair of furring strip body side panels 612 are arranged spaced apart in the width direction H of the furring strip 6. The pair of furring strip body side panels 612 each have a pair of lateral engagement openings 612a that open toward the ends of the furring strip 6 in the longitudinal direction X.

[0019] Two side engagement openings 612a are provided at each of one end and the other end of the longitudinal direction X of the furring strip body hollow portion 611. The two side engagement openings 612a are arranged opposite each other in the width direction H at each of one end and the other end of the longitudinal direction X of the furring strip body hollow portion 611.

[0020] 7, the bottom plate 613 is formed with a recess 613a recessed from the front end of the furring edge engaging member 62 side in the longitudinal direction X to the rear side. When the furring edge engaging member 62 is attached to the furring edge main body 61, the lower regulating protrusion 624 of the furring edge engaging member 62 is disposed in the recess 613a.

[0021] The pair of furring strip engaging members 62 are respectively inserted and attached to small openings 615 at both ends in the longitudinal direction X of the furring strip main body 61. The furring strip engaging members 62 are configured to be elastically deformable.

[0022] The furring sill engagement member 62 has an engagement member main body 621, a rafter engagement elastic convex portion 622, a pair of furring sill main body engagement elastic convex portions 623 (furring sill main body side engagement portions), and a lower regulating convex portion 624.

[0023] The engaging member body 621 is formed in a cylindrical shape with the front side closed by the front panel 621a and the back side open at the small ends 615 at both ends in the longitudinal direction X of the furring strip body 61. Most of the engaging member body 621 is disposed inside the furring strip body 61.

[0024] The rafter engagement elastic protrusion 622 is formed protruding from the engagement member main body 621 toward the rafter 5. The rafter engagement elastic protrusion 622 is engageable with the side opening 513 of the rafter main body 51.

[0025] The rafter engagement elastic protrusion 622 is provided below the front plate 621a of the engagement member main body 621 on the end face on the rafter 5 side of the joist engagement member 62. The rafter engagement elastic protrusion 622 is formed on the front plate 621a such that the inner portion of the U-shaped groove that opens downward protrudes toward the rafter 5 side in an elastically deformable manner. When not pressed, the rafter engagement elastic protrusion 622 is disposed in a protruding position protruding toward the rafter 5 side, and when pressed, the rafter engagement elastic protrusion 622 is released from the elastically deformed state by being pressed and is disposed in the protruding position by being no longer pressed.

[0026] The rafter engagement elastic convex portion 622 has an inclined protruding surface 622a. The inclined protruding surface 622a is formed at an angle so as to gradually protrude from the front surface of the front plate 621a of the rafter engagement member 62 as it moves from the bottom to the top of the rafter engagement member 62. The inclined protruding surface 622a is a surface that is pressed against the side surface 512a of the rafter side plate 512 of the rafter main body 51 when the rafter 6 is attached to the rafter main body 51.

[0027] When the siding 6 is attached between adjacent rafters 5, as shown in Fig. 8, the siding 6 is moved from above to below between the adjacent rafters 5. By moving the siding 6 from above to below, the siding 6 is inserted between the adjacent rafters 5, and the inclined protruding surface 622a of the rafter engagement elastic convex portion 622 is pressed against the side surface 512a of the rafter side panel 512 of the rafter main body 51, so that the rafter engagement elastic convex portion 622 is temporarily pressed inward by elastic deformation.

[0028] As the rafter 6 is moved further downward, the rafter engagement elastic protrusion 622 is moved to the side opening 513 of the rafter body 51, and is no longer pressed from the elastically deformed state, so that the elastic deformation is released and the rafter body 51 is protruded toward the rafter body 51. As a result, the rafter engagement elastic protrusion 622 of the rafter 6 engages with the side opening 513 of the rafter body 51, so that the rafter 6 can be attached to the rafter body 51.

[0029] As shown in Fig. 7, a pair of furring strip body engaging elastic convex parts 623 are provided on a pair of engaging member side panels 621b formed at both ends of the engaging member body 621 in the width direction H. The furring strip body engaging elastic convex parts 623 can engage with the lateral engaging openings 612a of the furring strip body 61. The furring strip body engaging elastic convex parts 623 are formed such that the inner part of the U-shaped groove that opens at the rear protrudes laterally in an elastically deformable manner. When not pressed, the furring strip body engaging elastic convex parts 623 are arranged in a protruding position, and when pressed, they are pushed inward once by elastic deformation, and are no longer pressed, so that the elastic deformation is released and they are arranged in a protruding position.

[0030] The furring strip body engaging elastic convex portion 623 has an inclined protruding surface 623a. The inclined protruding surface 623a is formed at an angle so as to gradually protrude from the engaging member side plate 621b of the furring strip body engaging member 62 as it moves from the back side to the front side of the furring strip body engaging member 62. The inclined protruding surface 623a is a surface that is pressed against the inner surface of the furring strip body side plate 612 of the furring strip body 61 when the furring strip body engaging member 62 is attached to the furring strip body 61.

[0031] When attaching the furring strip engaging member 62 to the furring strip body 61, as shown in FIG. 7, the furring strip engaging member 62 is inserted into the small end 615 of the furring strip body 61. As a result, the inclined protruding surfaces 623a of the pair of furring strip body engaging elastic convex portions 623 are pressed against the inner surfaces of the pair of furring strip body side panels 612 of the furring strip body hollow portion 611 of the furring strip body 61, and are once pressed inward by elastic deformation. As the furring strip engaging member 62 is further inserted, the furring strip body engaging elastic convex portion 623 is moved to the side engaging opening 612a of the furring strip body 61, and is no longer pressed from the elastically deformed state, and the elastic deformation is released and the furring strip engaging member 62 is positioned at the protruding position. As a result, the pair of furring strip body engaging elastic convex portions 623 of the furring strip engaging member 62 engage with the pair of side engaging openings 612a of the furring strip body 61, so that the furring strip engaging member 62 can be attached to the furring strip body 61.

[0032] The lower restricting protrusion 624 is provided to protrude downward from the underside of the end of the engaging member main body 621 on the rafter 5 side. When the rafter 6 is attached between adjacent rafters 5, the lower restricting protrusion 624 can engage with the notched restricting portion 517a of the protruding portion of the rafter main body 51. The lower restricting protrusion 624 restricts the movement of the rafter 6 in the longitudinal direction of the rafter 5.

[0033] Next, we will explain the procedure for constructing the roof body 2. When constructing the roof body 2, first, the front frame 4 and the rafter hanger 3 are installed, and then multiple rafter bodies 51 are arranged side by side in the left-right direction so as to span the front frame 4 and the rafter hanger 3.

[0034] In this state, the siding 6 to which the siding engagement member 62 is attached is moved from the upper side to the lower side between the adjacent rafter bodies 51, as shown in Fig. 8. As a result, the siding 6 is moved downward, and the siding body engagement elastic convex portion 623 is pressed against the side surface 512a of the rafter side panel 512 of the rafter body 51, and is temporarily pressed inward by elastic deformation. As the siding 6 is moved further downward, the siding body engagement elastic convex portion 623 is moved to the side opening 513 of the rafter body 51, and is no longer pressed from the elastically deformed state, and is positioned in the protruding position.

[0035] Therefore, when the elastic deformation is released at the side opening 513 from the state in which the rafter 5 is pressed against the side of the rafter body 51 of the rafter 5 and elastically deformed, the rafter body engaging elastic protrusion 623 engages with the side opening 513 of the rafter body 51. This allows the rafter 6 to be easily attached between the adjacent rafter bodies 51 by simply moving the rafter 6 from above to below between the adjacent rafter bodies 51.

[0036] Next, above the joists 6, the panel material 7 is placed so as to straddle the adjacent rafter bodies 51, and the rafter cover 52 is attached so as to sandwich the end of the panel material 7 between the rafter bodies 51. In this manner, the roof body 2 can be easily constructed.

[0037] According to this embodiment, the following effects are achieved. The roof body 2 of this embodiment includes a plurality of rafters 5, a rafter 6 that extends between adjacent rafters 5 among the plurality of rafters 5 and is attached to the rafters 5, and a panel material 7 that is attached between adjacent rafters 5 above the rafter 6, the rafters 5 have a side opening 513 provided on a side of the rafter 5 midway along the longitudinal direction of the rafter 5, and the rafter 6 includes a long rafter main body 61 and a rafter engaging member 62 that is provided at an end of the rafter main body 61 in the longitudinal direction X, protrudes toward the rafter 5, and can engage with the side opening 513.

[0038] As a result, the siding 6 can be attached to the rafter 5 by engaging the siding engagement member 62 of the siding 6 with the side opening 513 of the rafter 5, so that the siding 6 can be easily attached to the rafter 5 without using screws.

[0039] In this embodiment, the siding engagement member 62 is configured to be elastically deformable, and when the siding 6 is moved from the upper side between the adjacent rafters 5, the elastic deformation is released at the side opening 513 from the state where it is pressed against the side of the rafter 5 and elastically deformed, and it engages with the side opening 513. As a result, by moving the siding 6 from the upper side to the lower side, it can be easily engaged with the side opening 513 of the rafter 5. Therefore, the siding 6 can be easily attached to the rafter 5.

[0040] In this embodiment, the rafter 5 includes a lower side extension 515 that extends laterally at the lower part and on which the joist 6 is arranged, and the lower side extension 515 has a notch restriction portion 517a that restricts movement of the joist 6 in the longitudinal direction of the rafter 5. This allows the joist 6 to be easily arranged on the rafter 5 while the movement of the joist 6 in the longitudinal direction of the rafter 5 is restricted.

[0041] In addition, in this embodiment, the furring strip engaging member 62 has a furring strip body engaging elastic convex portion 623 that can engage with the furring strip body 61. This makes it possible to easily attach the furring strip engaging member 62 to the furring strip body 61 simply by engaging the furring strip engaging member 62 with the furring strip body 61.

[0042] Although a preferred embodiment of the present disclosure has been described above, the present disclosure is not limited to the above-described embodiment and can be modified as appropriate. [Explanation of symbols]
