[0010] 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.

[0011] 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 on 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, and a plurality of panel members 6 attached between adjacent rafters 5 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.

[0012] The multiple rafters 5 extend in the front-to-rear direction of the roof body 2 and are arranged side by side in the left-to-right direction. As shown in Figures 2 and 3, the rafter 5 has a rafter body 51 and a rafter cover 56 (rafter upper member) that is arranged on top of the rafter body 51 and sandwiches the end of the panel material 6 between the rafter body 51 and the rafter cover 56. With the end of the panel material 6 sandwiched between the rafter body 51 and the rafter cover 56, the rafter 5 fixes the panel material 6 by a rafter locking mechanism 8.

[0013] 1, the rafter locking mechanisms 8 are disposed at intervals in the longitudinal direction of the rafter 5, for example, at two to four locations in the longitudinal direction of the rafter 5. In this embodiment, the end of the panel material 6 is sandwiched between the rafter body 51 and the rafter cover 56 by the rafter locking mechanisms 8, for example, at three locations in the longitudinal direction of the rafter 5.

[0014] 2 to 4, a locking member 81 of a rafter locking mechanism 8 is housed inside the rafter body 51. As shown in Figures 5 and 6, the rafter body 51 has a body-side hollow portion 52 having a hollow portion, a pair of standing pieces 53 protruding upward from the upper surface of the body-side hollow portion 52, a pair of body-side panel holding portions 54, and a pair of lateral protruding pieces 55 protruding from the lower end of the body-side hollow portion 52 to both outsides in the width direction of the body-side hollow portion 52.

[0015] The body-side hollow portion 52 has a body-side upper plate 521 having an upper surface opening 521a (upper side opening) and a body-side lower plate 522 having a lower surface opening 522a (lower side opening).

[0016] The bottom opening 522a is provided in the body-side bottom plate 522 arranged on the lower side of the rafter body 51. The bottom opening 522a is formed so that the locking member 81 of the rafter locking mechanism 8 can be inserted into the inside of the rafter body 51 from below the rafter body 51. When the locking member 81 is inserted and accommodated inside the rafter body 51, the entirety of the locking member 81 is accommodated inside the rafter body 51 from below the bottom opening 522a through the bottom opening 522a. The bottom opening 522a is opened so that the locking member 81 can be operated from the lower side of the rafter body 51.

[0017] The top opening 521a is provided in the main body-side top plate 521 arranged on the upper side of the rafter main body 51. The top opening 521a opens to the rafter cover 56 side. Around the periphery of the top opening 521a, a case body 814 of the locking member 81 is attached to the lower surface of the main body-side top plate 521 with the locking member 81 housed inside the rafter main body 51. As shown in FIG. 4, a lock receiving engagement portion 821 of a lock receiving portion 82 (described later) is inserted into the top opening 521a from the upper side of the rafter main body 51.

[0018] As shown in Figures 5 and 6, the rafter cover 56 has a cover side upper panel 561, a cover side hollow portion 562 formed at the lower part of the cover side upper panel 561, and a pair of cover side panel retaining portions 563 provided at both ends of the rafter cover 56 in the width direction.

[0019] The rafter main body 51 and the rafter cover 56 (rafter upper member) are attached by a rafter locking mechanism 8, as shown in Fig. 4. The rafter locking mechanism 8 includes a locking member 81, a lock receiving portion 82, and a bottom cover member 83, as shown in Figs.

[0020] The locking member 81 is provided on the rafter body 51. The locking member 81 is housed inside the rafter body 51. When the locking member 81 is attached to the rafter body 51, it is inserted into the inside of the rafter body 51 from below the rafter body 51 through the bottom opening 522a. The locking member 81 is fixed to the bottom surface of the main body side top plate 521 of the main body side hollow portion 52 at the periphery of the top opening 521a with screws.

[0021] The locking member 81 can be engaged with the lock receiving portion 82 of the rafter cover 56 from below the rafter body 51. As shown in Figures 7 and 8, the locking member 81 has a lock engagement piece 811 (first engagement portion), an operation portion 812 that can operate the lock engagement piece 811 by rotating it from below, a rotating shaft member 813 that forms a rotating shaft, and a case body 814.

[0022] The lock engagement piece 811 is formed in an arc shape that rotates around the rotating shaft member 813. The lock engagement piece 811 (first engagement portion) rotates in conjunction with the operation of the operating portion 812, and engages with a lock receiving engagement portion 821 (second engagement portion) (described later) of the lock receiving portion 82.

[0023] As shown in Figures 4 to 6, the lock receiving portion 82 is provided on the rafter cover 56. The lock receiving portion 82 is fixed to the underside of the rafter cover 56 with screws. The lock receiving portion 82 has a lock receiving engagement portion 821 (second engagement portion) with which the lock engagement piece 811 (first engagement portion) operated by the operation portion 812 of the locking member 81 engages.

[0024] The lock receiving engagement portion 821 is formed in an arc-shaped groove, and is engageable with the lock engaging piece 811 of the locking member 81. The lock receiving engagement portion 821 is inserted into the upper surface opening 521a of the rafter main body 51, as shown in Fig. 4. The lock receiving engagement portion 821 is engaged with the lock engaging piece 811 of the locking member 81 in a state where it is inserted into the upper surface opening 521a of the rafter main body 51.

[0025] In the locking member 81 and lock receiving portion 82 configured as described above, by rotating the operating portion 812, the lock engagement piece 811 can be moved between a locked position (see Figure 4) in which it engages with the lock receiving engagement portion 821 and an unlocked position (see Figure 8) in which it does not engage with the lock receiving engagement portion 821.

[0026] As shown in Figures 3 and 4, the lower cover member 83 is attached to the underside of the rafter body 51 so as to cover the lower opening 522a below the locking member 81 housed inside the rafter body 51 through the lower opening 522a.

[0027] Next, a procedure for fixing the rafter cover 56 to the rafter body 51 by the rafter locking mechanism 8 will be described. Before fixing the rafter cover 56 to the rafter body 51, the locking member 81 is attached to the rafter body 51 in advance. In addition, before fixing the rafter cover 56 to the rafter body 51, the lock receiving portion 82 is attached to the rafter cover 56 in advance.

[0028] 6, the locking member 81 is inserted from below the lower side of the rafter body 51 into the lower side of the lower opening 522a of the main body lower plate 522 of the main body hollow portion 52, and attached to the lower surface of the main body upper plate 521 of the main body hollow portion 52 at the periphery of the upper opening 521a by screws from above. Also, when the lock receiving portion 82 is attached to the rafter cover 56, the lock receiving portion 82 is attached to the lower surface of the lower plate of the rafter cover 56 by screws from below.

[0029] When constructing the roof body 2, first, the front frame 4 and the rafter hanger 3 are installed, and then multiple rafter bodies 51 with locking members 81 attached are arranged in a line in the left-right direction so as to span the front frame 4 and the rafter hanger 3.

[0030] Next, the end of the panel material 6 is placed on the body-side panel holding portion 54 of the rafter body 51 so as to straddle the adjacent rafter bodies 51. Next, the rafter cover 56 with the lock receiving portion 82 attached is placed on the upper side of the rafter body 51 so as to sandwich the end of the panel material 6. The lock receiving engagement portion 821 of the lock receiving portion 82 attached to the rafter cover 56 is inserted into the upper surface opening 521a of the rafter body 51.

[0031] In this state, by rotating the operating portion 812 of the locking member 81 from the state shown in Fig. 8, with the end of the panel material 6 sandwiched between the rafter body 51 and the rafter cover 56, the locking member 81 is operated from the below side of the rafter body 51 to engage the lock engagement piece 811 of the locking member 81 with the lock receiving engagement portion 821 of the lock receiving portion 82, as shown in Fig. 4. As a result, with the panel material 6 sandwiched between the rafter body 51 and the rafter cover 56, the rafter cover 56 can be easily attached to the upper side of the rafter body 51 by operating the locking member 81 from the below side of the rafter 5.

[0032] Next, a bottom cover member 83 is attached to the periphery of the bottom opening 522a so as to close the bottom opening 522a of the body-side bottom plate 522 of the body-side hollow portion 52 of the rafter body 51. This makes it possible for the locking member 81 and lock receiving portion 82 housed inside the rafter 5 to be invisible from below the roof body 2, improving the design.

[0033] According to this embodiment, the following effects are achieved: The roof body 2 of this embodiment comprises a plurality of rafters 5 arranged side by side in a predetermined direction, and a panel material 6 arranged between adjacent rafters 5 of the plurality of rafters 5, and the rafters 5 have a rafter body 51 and a rafter cover 56 arranged on the upper part of the rafter body 51 and sandwiching an end of the panel material 6 between the rafter body 51 and the rafter cover 56, and also comprises a lock receiving portion 82 provided on the rafter cover 56, and a locking member 81 provided on the rafter body 51 and capable of engaging with the lock receiving portion 82 from the lower side of the rafter body 51.

[0034] With this, with the panel material 6 sandwiched between the rafter body 51 and the rafter cover 56, by operating the locking member 81 from the lower side of the rafter 5, the rafter cover 56 can be easily attached to the upper side of the rafter body 51. Therefore, the rafter body 51 and the rafter cover 56 with the panel material 6 sandwiched therebetween can be easily fixed.

[0035] In this embodiment, the locking member 81 is housed inside the rafter body 51, which has an upper opening 521a provided on the upper side and opening into the rafter cover 56, and a lower opening 522a opening to allow the locking member 81 to be operated from the lower side. This allows the locking member 81 to be housed inside the rafter 5, so that the structure for fixing the rafter body 51 and the rafter cover 56 can be configured compactly. In addition, since the locking member 81 can be housed inside the rafter 5, the structure for fixing the rafter body 51 and the rafter cover 56 cannot be seen from the outside, so that the design can be maintained.

[0036] In this embodiment, the locking member 81 has a lock engagement piece 811 and an operating portion 812 that can operate the lock engagement piece 811 by rotating it from below, and the lock receiving portion 82 has a lock receiving engagement portion 821 that engages with the lock engagement piece 811 operated by the operating portion 812. This makes it possible to easily engage the locking member 81 with the lock receiving portion 82 by rotating the operating portion 812 from below the rafter 5.

[0037] In the construction method of the roof body of this embodiment, with the end of the panel material 6 sandwiched between the rafter body 51 and the rafter cover 56, the locking member 81 is operated from below the rafter body 51 to engage the locking member 81 with the lock receiving portion 82. In this way, with the panel material 6 sandwiched between the rafter body 51 and the rafter cover 56, the rafter cover 56 can be easily attached to the upper side of the rafter body 51 by operating the locking member 81 from below the rafter 5.

[0038] 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.

[0039] For example, in the above embodiment, the lock receiving portion 82 is configured as a separate part from the rafter cover 56 (rafter upper member), but this is not limited thereto. The lock receiving portion 82 may be provided integrally with the rafter cover 56 (rafter upper member).

[0040] In the embodiment, the lock receiving engagement portion 821 (second engagement portion) of the lock receiving portion 82 is formed in an arc-shaped groove, but is not limited thereto. The lock receiving engagement portion 821 (second engagement portion) of the lock receiving portion 82 does not have to be arc-shaped as long as it has a shape that allows the lock engagement piece (first engagement portion) to be caught and engaged.

[0041] In the above embodiment, the entire locking member 81 is accommodated inside the rafter body 51. However, this is not limited to this. A part of the locking member 81 may be disposed outside the rafter body 51. [Explanation of symbols]
