[0002] 2. Description of the Related Art Conventionally, there has been known a roof structure including a roof body and a gap sealing material that seals the gap between the roof body and a building frame (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 5914908 Summary of the Invention [Problem to be solved by the invention]

[0004] In the roof structure described in Patent Document 1, when viewed from below the roof, the unevenness and screws of the connecting members that connect the gap sealing material and the roof body are exposed. Therefore, in roof structures equipped with gap sealing materials, there is a demand for improving the design when viewed from below the roof structure.

[0005] The present invention aims to provide a roof structure having a gap sealing material and a construction method for the roof structure that can improve the design. [Means for solving the problem]

[0006] The present invention comprises a roof body (e.g., roof body 4 described below) whose tip is arranged opposite a main body (e.g., main body 10 described below), a gap filler material (e.g., gap filler material 71 described below) that fills the gap between the tip of the roof body and the main body, and a connecting member (e.g., mounting frame body 72 described below) that connects the tip of the roof body to the gap filler material, wherein the connecting member relates to a roof structure (e.g., terrace 1 described below) that is arranged on top of the roof body.

[0007] It is also preferable that the connecting member is connected to the base end side of the gap sealing material, and the connecting member is fixed to the upper surface of the roof body.

[0008] In addition, it is preferable that the connecting member has a locking portion (for example, the locking projection 743 described below) that can be locked onto a hook portion (for example, the hook piece 423 described below) provided on the tip side of the upper surface of the roof body.

[0009] Furthermore, it is preferable that the connecting member has a first member (e.g., the first mounting frame 73 described below) formed in an elongated shape along the direction in which the tip edge of the roof body extends, and a plurality of second members (e.g., the second mounting frame 74 described below) arranged in a row at intervals in the longitudinal direction of the first member along the direction in which the tip edge of the roof body extends, and that the connecting member fixes the gap filler material with the base end portion of the gap filler material sandwiched between the first member and the plurality of second members.

[0010] In addition, the first member and the second member are fixed by a screw member (e.g., screw member 742a described later) that penetrates the first member and the second member in the vertical direction and has a head (e.g., screw head 742b described later) positioned at the bottom, and it is preferable that the head of the screw member is positioned above the roof body when the gap sealant is fixed between the first member and the second member.

[0011] It is also preferable that the second member further comprises a pillar material (e.g., support pillar 2 described below) and a beam (e.g., beam 3 described below) connected to the pillar material, with its base end positioned on the pillar material side and extending from the base end to its tip end, and that the second member is positioned at a position avoiding the beam.

[0012] The present invention also relates to a method for constructing a roof structure, the method including the steps of connecting the connecting member and the gap sealing material, and fixing the connected connecting member and the gap sealing material to an upper surface of the roof body.

[0015] Hereinafter, one embodiment of the roof structure of the present invention will be described 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 in this embodiment, an example in which the roof structure is applied to a terrace 1 will be described, but the present invention is not limited to this.

[0017] In the description of this embodiment, the direction in which the multiple long members (long members) 41 constituting the roof body 4 of the terrace 1 extend is also referred to as the left-right direction (the longitudinal direction of the long members 41). The direction in which the beams 3 extend is also referred to as the front-rear direction, and in the direction in which the beams 3 extend, the side of the support pillars 2 is also referred to as the base end side of the terrace 1, and the side opposite the support pillars 2 is also referred to as the tip side of the terrace 1.

[0018] 1 to 3, the terrace 1 of this embodiment is a so-called cantilever structure terrace in which a roof body 4 is supported by a pair of pillars 2 at the base end side in the front-to-rear direction (the left front side in Fig. 1 and the left side in Fig. 2). The terrace 1 of this embodiment is also configured with a hanging structure in which the roof body 4 is hung and connected to the lower part (lower part) of the beams 3 connected to the pillars 2. The terrace 1 is an independent terrace in which the tip of the roof body 4 is disposed opposite the structure 10, which has a building wall and a building opening, and is spaced apart from the structure 10. The gap between the roof body 4 and the structure 10 is sealed by a gap sealing unit 7.

[0019] 1 to 3, a terrace 1 of this embodiment comprises a pair of posts 2 (pillar members) erected on the ground 11, beams 3 extending from the upper ends of the posts 2 in a direction intersecting the posts, a roof body 4 connected to the lower part of the beams 3, and a gap closing unit 7. The posts 2, beams 3, and multiple long members 41 constituting the roof body 4 are formed from extruded aluminum members, and have a hollow structure with a hollow cross section.

[0020] As shown in FIG. 1, the pair of support pillars 2 are disposed at a distance from each other in the left-right direction of the terrace 1 on the base end side of the terrace 1 (the front left side in FIG. 1). 1 and 4, the support 2 has a hollow support body 21 having a rectangular tubular cross section, and a pair of cover mounting walls 22 that protrude from the side surface of the support body 21 facing the roof body 4 toward the roof body 4 and extend in the vertical direction. A support cover member 23 is attached to the pair of cover mounting walls 22. A support cap 24 is disposed on the upper end of the support 2 so as to cover the opening at the upper end of the support 2.

[0021] Water discharged from the roof body side gutter component 40 (described later) of the roof body 4 flows between the pillar body 21 and the pillar cover member 23. Since water discharged from the roof body side gutter component 40 (described later) flows between the pillar body 21 and the pillar cover member 23, the pillar body 21 and the pillar cover member 23 are configured as a pillar side gutter component 20 (pillar side gutter structure) as shown in FIG. 4. In this embodiment, a rain gutter hose or the like is not arranged between the pillar body 21 and the pillar cover member 23, and the vertical gutter is configured only by the pillar body 21 and the pillar cover member 23. The pillar side gutter component 20 is not visible from the outside of the terrace 1 because the side surface of the pillar body 21 on the roof body 4 side is covered by the pillar cover member 23. Therefore, the fact that the pillar 2 has a gutter function is not visible from the outside, improving the design.

[0022] 1 and 2, a drainage guide member 6 is attached to the lower end of the pair of pillars 2 on one side in the left-right direction (the front right side in FIG. 1) near the ground 11. The drainage guide member 6 guides water flowing through a pillar side gutter component 20 (described below) composed of a pillar main body 21 and a pillar cover member 23 to the outside on one side in the front-to-rear direction (the opposite side to the building) and discharges it.

[0023] The pair of beams 3 are arranged spaced apart in the left-right direction of the terrace 1. Each of the pair of beams 3 extends in the front-rear direction and is formed with a downward slope descending toward the support column 2. The base end of the beam 3 is arranged on the support column 2 side and extends from the base end to the tip end. The base end ends (left end ends) of the pair of beams 3 are connected to the upper ends of the support column 2 via an L-shaped connecting member 25 as shown in FIG. 4. The roof body 4 is connected to the lower parts of the pair of beams 3.

[0024] As shown in FIGS. 1 and 4, each of the pair of beams 3 has a beam-side hollow portion 31 formed in a rectangular cylindrical cross section, an extending plate portion 32 (lower extending plate), and an end cap 33.

[0025] The tip 31a of the beam-side hollow portion 31 is formed with an upward inclination from the tip side toward the base end side (the support 2 side) so that the upper end portion on the tip side is inclined and cut out. Therefore, the tip 31a of the beam 3 has a shape that is difficult to see from the ground 11 side below the tip side of the roof body 4 when the roof body 4 is connected to the lower part of the beam 3. Therefore, since the beam 3 is difficult to see from the ground 11 side below the tip side of the roof body 4, the design can be improved. In addition, in this embodiment, the beam 3 does not extend to the tip of the roof body 4, and the tip of the beam 3 is located closer to the base end side (the support 2 side) than the tip position of the roof body 4. As a result, a space for arranging the mounting frame body 72 of the gap closing unit 7 is secured at the tip of the upper surface of the roof body 4.

[0026] 3 and 4, the extension plate portion 32 extends from the lower end of the beam-side hollow portion 31 toward the center side in the left-right direction of the roof body 4 (the side of the other beam 3 of the pair of beams 3) and is formed in a plate shape extending in the front-rear direction. The extension plate portion 32 is fixed to the roof body 4 at the extension plate portion 32 by a plurality of screw members 101 arranged side by side in the front-rear direction.

[0027] The roof body 4 is disposed below the beams 3. As shown in Fig. 4, the roof body 4 has a hanging structure in which the roof body 4 is suspended from the lower parts of a pair of beams 3, and is attached (connected) to the lower parts of the pair of beams 3. The roof body 4 is formed by multiple long members (long members) 41 that are arranged side by side in the extension direction of the beams 3 and are fitted and connected to each other.

[0028] Each of the long members 41 extends in the left-right direction of the terrace 1 (in a direction perpendicular to the direction in which the beams 3 extend) and has a predetermined thickness. Each of the long members 41 is formed of an extruded aluminum material, and has a hollow structure with a hollow section formed in a hollow shape. The roof body 4 has an upper surface 4a and a lower surface 4b formed flat (planar). The roof body 4 is arranged on a downward slope with the support column 2 side descending, and the upper surface 4a and the lower surface 4b are formed on a downward slope with the support column 2 side descending. By connecting the long members 41 formed of an extruded aluminum material to form the roof body 4, the long members 41 can be used as the surface material of the roof body 4 and the strength of the roof body 4 can be ensured. In addition, by forming the long members 41 that form the roof body 4 from a material having a hollow section, the roof body 4 itself can be used as a strength member, and there is no need to provide a separate member for increasing the strength of the roof body 4. Therefore, the number of parts constituting the roof body 4 can be reduced.

[0029] 4, the multiple long members 41 constituting the roof body 4 are comprised of a tip-side member 42 arranged at the most tip end side, a gutter-forming member 44 arranged at the most base end side on the pillar 2 side, and multiple intermediate members 43 arranged between the tip-side member 42 and the gutter-forming member 44. Each of the multiple long members 41 is directly fixed and connected to the beam 3 by screw members 101. In detail, the screw member 101 is moved from above through the extension plate portion 32 of the beam 3 and the top plate (base end upper extension piece 427 of the tip side profile member 42, base end upper extension piece 437 of the intermediate profile member 43) of the long profile member 41 (tip side profile member 42, intermediate profile member 43), and the screw member 101 is screwed into the back plate member 108 arranged below the top plate (base end upper extension piece 427 of the tip side profile member 42, base end upper extension piece 437 of the intermediate profile member 43), thereby fixing the long profile member 41 to the beam 3.

[0030] The tip side shape member 42 is arranged on the tip side of the roof body 4 connected to the beam 3, as shown in Fig. 4. The tip side shape member 42 has a first tip hollow portion 421 arranged on the tip side, a second tip hollow portion 422 arranged on the base end side of the first tip hollow portion 421, a base end side upper extension piece 427 (fixing portion) formed on the base end side of the second tip hollow portion 422, and a base end side lower piece 428 formed on the base end side of the second tip hollow portion 422, as shown in Fig. 5.

[0031] A hook piece 423 (hook portion) is formed on the upper surface of the end portion on the tip side of the first tip hollow portion 421, and a fin 424 protruding downward is formed on the lower surface. The hook piece 423 has a U-shaped cross section that opens towards the support column 2 side. The plate-shaped protruding portion 341 of the tongue-shaped member 34 (temporary support portion) is inserted into the open side of the hook piece 423. The hook piece 423 can be hooked onto the plate-shaped protruding portion 341 of the tongue-shaped member 34, and can be maintained in a state where it is hooked onto the tongue-shaped member 34 when the roof body 4 is constructed.

[0032] The tongue-shaped member 34 is fixed to the tip side of the beam 3, and when the roof body 4 is constructed, the tip side shape member 42 can be temporarily supported by hooking the hook piece 423 of the tip side shape member 42. The tongue-shaped member 34 has a crank-shaped cross section, and a plate-shaped protruding portion 341 is formed on the tip side. An end portion 342 on the base end side of the tongue-shaped member 34 is fixed to the underside of the tip of the beam 3.

[0033] The plate-like protrusion 341 is formed in a plate shape and protrudes approximately horizontally from the tip of the beam 3 toward the tip side of the roof body 4. The plate-like protrusion 341 extends from the tip of the beam 3 to the hook piece 423 of the tip side profile 42 on the upper surface of the tip of the roof body 4. This allows the tip side profile 42 to be temporarily supported on the beam 3 by hooking the plate-like protrusion 341 onto the hook piece 423 of the first tip hollow portion 421 when attaching the tip side profile 42 to the beam 3. Since the tongue-like member 34 is arranged on the upper surface of the roof body 4, it is not visible from below the roof body 4, ensuring design.

[0034] The base-end upper extension piece 427 extends toward the base end in the front-rear direction from the upper end of the base end side (left side in FIG. 5) of the second tip hollow portion 422. The base-end upper extension piece 427 is disposed at the upper end of the end of the base end side (pillar 2 side) in the front-rear direction of the tip-side profile member 42, and constitutes a fixing part (screw fixing part) that is fixed to the extension plate part 32 of the beam 3 by the screw member 102.

[0035] At the end of the base end side upper extension piece 427 on the base end side (left side in Figure 5) in the front-to-rear direction of the roof body 4, a lateral extension wall 427b extending laterally and a downward extension wall 427c extending downward are formed.

[0036] A bead material 401 (waterstop material) attached to the tip end of the adjacent intermediate shape member 43 is pressed against the surface of the downward extending wall 427c on the base end side in the front-to-rear direction of the roof body 4. The bead material 401 functions as a waterstop portion disposed at the connecting portion between the tip side shape member 42 and the intermediate shape member 43. The bead material 401 is formed so as to extend in the direction in which the connecting portion of the tip side shape member 42 and the adjacent intermediate shape member 43 (long shape member 41) extends, i.e., along the long dimension (lengthwise direction) of the long shape member 41.

[0037] The base end lower piece 428 extends toward the base end from the lower end portion on the base end side in the front-to-rear direction of the roof body 4 at the second tip hollow portion 422. A hook engagement portion 428a (hook portion) protruding upward is formed at the end portion on the base end side of the base end lower piece 428.

[0038] 5, the hook engagement portion 428a is formed at the lower end of the tip side profile 42 at the end portion on the base end side in the front-to-rear direction of the tip side profile 42 attached to the beam 3. The hook engagement portion 428a rises upward from the base end lower piece 428 arranged at the lower end at the end portion on the base end side in the front-to-rear direction of the tip side profile 42 attached to the beam 3, and is formed in a T-shape at the rising upper end portion extending in the width direction perpendicular to the longitudinal direction.

[0039] The hook engagement portion 428a of the tip side frame 42 can engage with a tip side lower protruding piece 436 protruding toward the tip side from the side surface of the lower end portion on the tip side of the adjacent intermediate frame 43, and a hook piece 435b (described later) of a hook extension piece 435 formed on the end portion on the tip side of the adjacent intermediate frame 43. The hook engagement portion 428a can be maintained in a state where it is hooked on the hook piece 435b of the hook extension piece 435.

[0040] Water that overflows from the middle gutter component 410 (water-stopping section) of the adjacent intermediate profile 43 flows over the upper surface of the base end lower piece 428. The upper surface of the base end lower piece 428 forms the lower gutter component 420, which is located at the lower level in the vertical direction inside the roof body 4. The lower gutter component 420 has a gutter function that drains water. The lower gutter component 420 receives water that passes through the bead material 401, is received by the middle gutter component 410, and overflows from the middle gutter component 410 (water-stopping section). The lower gutter component 420 allows water that has overflowed from the middle gutter component 410 and been received to flow to both left and right end sides.

[0041] As shown in FIG. 4, a plurality of intermediate members 43 are arranged side by side between the tip end side member 42 and the gutter forming member 44 . As shown in Figure 6, the intermediate profile 43 has a first intermediate hollow section 431 arranged on the tip side, a second intermediate hollow section 432 arranged on the base end side of the first intermediate hollow section 431, a bead material mounting recess 433 formed on the side surface of the upper end portion on the tip side of the first intermediate hollow section 431, an L-shaped middle gutter section 434 extending from the side surface on the tip side of the first intermediate hollow section 431 to the tip side, an L-shaped hook extension piece 435 extending downward from the lower end of the tip side end of the middle gutter section 434, a tip side lower extension piece 436 protruding toward the tip side from the side surface of the lower end portion on the tip side profile 42 side of the first intermediate hollow section 431, a base side upper extension piece 437 formed on the base end side of the second intermediate hollow section 432, and a base side lower piece 438 formed on the base end side of the second intermediate hollow section 432.

[0042] As shown in Fig. 6, an opening 439 that opens downward is formed on the lower side of the end portion on the tip side of the intermediate shape member 43. The opening 439 is formed by an end side 431a extending in the vertical direction arranged on one side of the first intermediate hollow portion 431 in the middle gutter portion 434, and an L-shaped hook extension piece 435. On the opening edge of the opening 439, an opposing protrusion 439a is formed that protrudes from the opening edge of the opening 439 to the inside of the opening 439 in an opposing relationship to each other. In this embodiment, the opposing protrusion 439a is composed of the tip side lower protrusion piece 436 and a hook piece 435b (described later) of the L-shaped hook extension piece 435, and protrudes and extends toward the inside of the opening 439 so as to approach each other.

[0043] In the tip side profile 42 and intermediate profile 43 configured as described above, when the adjacent tip side profile 42 and intermediate profile 43 are connected, the hook engagement portion 428a of the tip side profile 42 is positioned inside the opening 439 of the adjacent intermediate profile 43 and hooks onto and engages with the opposing protrusion 439a (the tip side lower protrusion piece 436, the hook piece 435b of the L-shaped hook extension piece 435) so as to restrict movement in the vertical direction.

[0044] The bead material mounting recess 433 is disposed opposite the downward extending wall 427c of the tip-side profile 42 adjacent to the tip side. An upper surface 433a of the bead material mounting recess 433 is formed at a position one step lower than the upper surface 4a of the roof body 4. The bead material mounting recess 433 extends in the direction in which the connecting portions of adjacent elongated profile members 41 extend, i.e., along the long dimension direction (lengthwise direction) of the elongated profile members 41.

[0045] A bead material 401 is attached to the bead material attachment recess 433. When attached to the bead material attachment recess 433, the bead material 401 presses the downward extending wall 427c of the tip side profile member 42 adjacent to the tip side. The bead material 401 is disposed at the connection portion between the tip side profile member 42 and the intermediate profile member 43, and functions as a water stopper portion.

[0046] The middle gutter section 434 has a bottom wall section 434a and an upright piece 434b. The middle gutter section 434 constitutes a middle gutter component 410 located in the middle section in the vertical direction inside the roof body 4. The middle gutter component 410 has a gutter function to allow water to flow, and also functions as a water stopping section. The middle gutter component 410 receives water that has passed through the bead material 401 and was not able to be stopped by the bead material 401, and allows the received water to flow to both ends in the left and right direction.

[0047] The L-shaped hook extension piece 435 has a downward extension piece 435a and a hook piece 435b extending from a lower end of the downward extension piece 435a toward the widthwise center of the intermediate extrusion member 43. The hook piece 435b is engageable with a hook engagement portion 428a formed on the end portion on the base end side in the front-rear direction of the adjacent tip side extrusion member 42. The hook piece 435b is rotatable about the hook engagement portion 428a in a state of being engaged with the hook engagement portion 428a.

[0048] When attaching an adjacent intermediate member 43 next to the tip-side member 42, the hook extension piece 435 of the intermediate member 43 can be hooked to the hook engagement portion 428a of the tip-side member 42 to which the extension plate portion 32 of the beam 3 is connected, thereby temporarily placing the intermediate member 43 below the beam 3. In addition, with the hook extension piece 435 of the intermediate member 43 hooked to the hook engagement portion 428a of the tip-side member 42, the intermediate member 43 can be rotated around the tip of the hook extension piece 435, thereby placing the intermediate member 43 at the attachment position. When the intermediate profile 43 is placed in the mounting position, the intermediate profile 43 is attached to the base end side of the tip side profile 42 in the fore-and-aft direction with the hook extension piece 435 of the intermediate profile 43 engaged with the hook engagement portion 428a of the tip side profile 42.

[0049] Regarding the base end upper extension piece 437 and the base end lower piece 438 of the intermediate extrusion member 43, those points which will not be described are similar in structure to the base end upper extension piece 427 and the base end lower piece 428 of the tip end side extrusion member 42. Therefore, the reference characters corresponding to the reference characters described in the structure of the base end upper extension piece 437 and the base end lower piece 438 of the intermediate extrusion member 43 will be used, and description thereof will be omitted.

[0050] Moreover, the configurations of the multiple intermediate members 43 arranged in succession are all the same, so the description thereof will be omitted. When an adjacent intermediate member 43 is attached next to an intermediate member 43 connected to a beam 3, similarly to the case of attaching the intermediate member 43 next to the tip-side member 42, the intermediate member 43 can be temporarily placed below the beam 3 by hooking the hook extension piece 435 of the intermediate member 43 to the hook engagement portion 438a of the intermediate member 43 connected to the extension plate portion 32 of the beam 3. Moreover, by rotating the intermediate member 43 around the hook extension piece 435 in a state in which the hook extension piece 435 of the intermediate member 43 is hooked to the hook engagement portion 438a of the intermediate member 43, the intermediate member 43 can be placed at the attachment position. When the adjacent intermediate extrusions 43 are positioned at the mounting position, the adjacent intermediate extrusions 43 are mounted on the base end side in the fore-and-aft direction of the intermediate extrusions 43, with the hooking engagement portion 438a of the intermediate extrusions 43 engaging with the hooking extension piece 435 of the adjacent intermediate extrusions 43.

[0051] The gutter forming members 44 are arranged in parallel at the end of the base end side (the support pillar 2 side) in the direction in which the multiple long members 41 are lined up in the roof body 4, and are formed from long members whose upper sides open upward as shown in Fig. 7. In this embodiment, the gutter forming members 44 are formed from a solid material that does not have a hollow portion, and are formed into a U-shaped cross section whose upper side opens. Note that the gutter forming members 44 are not limited to this, and may be formed into a shape whose upper side opens by cutting out the upper surface of a long member made of aluminum material with a hollow structure having a hollow portion.

[0052] The gutter forming member 44 constitutes a roof body side gutter forming part 40 at the end closest to the base end on the support 2 side of the roof body 4, which receives and circulates water that flows over the upper surface 4a of the roof body 4 towards the base end and reaches the end on the base end side. The roof body side gutter forming part 40 is disposed at the end on the downstream side of the water flowing over the upper surface 4a of the roof body 4. In this embodiment, the roof body side gutter forming part 40 is disposed at the downward sloping end of the roof body 4, at the end of the roof body 4 on the support 2 side on the base end side.

[0053] Since the roof body side gutter component 40 is open at the upper side, when the roof body side gutter component 40 is viewed from below the roof body 4, only the flat (planar) underside of the long member 41 is visible, and the gutter can be configured without making it clear that there is a gutter on the upper surface 4a of the roof body 4, thereby improving the design.

[0054] 7, the configuration of the tip end of the gutter-forming member 44 is similar to that of the tip end of the intermediate member 43, so the configuration of the tip end is given a corresponding reference numeral and a description thereof will be omitted. In addition, when an adjacent gutter-forming member 44 is attached next to an intermediate member 43 connected to a beam 3, the same procedure is used as when the intermediate member 43 is attached next to the tip-side member 42.

[0055] The configuration of the gutter constituent member 44 other than the end portion on the tip side will be described in detail. The gutter constituent member 44 has a gutter constituent part 441. The gutter constituent part 441 has a gutter constituent part main body 442 having a generally U-shape that is open at the top, a base end side upper inward extending piece 451 (upper surface plate) arranged on the base end side, a tip end side upper inward extending piece 452 arranged on the tip end side, a draining fin 453 arranged on the base end side, and a base end side upper wall 454 arranged on the base end side.

[0056] The gutter forming body 442 receives water that has flowed toward the support pillar 2 on the upper surface 4a of the roof body 4 from the open upper portion. A lead-out opening 442a (drainage port) is formed on the side surface of the second tip hollow portion 422.

[0057] 7, the outlet opening 442a is formed by penetrating a side surface of the gutter forming portion main body 442 laterally toward the support 2 side in a portion where one support 2 on the base end side in the front-rear direction (the support 2 on the right front side in FIG. 1) is disposed. A side opening 471 (described later) of an L-shaped guide member 47 is connected to the outlet opening 442a.

[0058] The guide member 47 guides water that has flowed into and accumulated in the roof body side gutter configuring part 40, to the support pillar side gutter configuring part 20. The guide member 47 is formed in a cylindrical shape that slopes diagonally downward toward the support pillar side gutter configuring part 20, and has a side opening 471 and a bottom end opening 472. The side opening 471 on one side of the guide member 47 is connected to an outlet opening 442a formed on the side of the gutter configuring part main body 442 (roof body side gutter configuring part 40), and the bottom end opening 472 on the other side is inserted between the support pillar main body part 21 and the support pillar cover member 23, and opens into the interior of the support pillar side gutter configuring part 20.

[0059] 7, the base end side upper inwardly extending piece 451 protrudes inward from the inner surface on the upper side of the gutter configuring shape material 44 at the base end side of the gutter configuring shape material 44. A guide member 47 is fixed to the base end side upper inwardly extending piece 451 by a screw member 451a.

[0060] As shown in Figures 8 to 10, the base end upper inward extension piece 451 formed at the widthwise end of the gutter constituent profile 44 on the pillar 2 side is fixed to the longitudinal end of the extension plate portion 32 of the beam 3 on the pillar 2 side by a clip member 5 (clamping member). The clip member 5 is U-shaped in side view and includes a U-shaped portion in cross section. The clip member 5 vertically clamps the longitudinal end of the extension plate portion 32 of the beam 3 on the support 2 side and the base end upper inward extending piece 451 of the gutter configuring shape member 44. At the base end end of the beam 3, the base end end of the extension plate portion 32 of the beam 3 is arranged to overlap above the base end upper inward extending piece 451 of the gutter configuring shape member 44.

[0061] 8 and 9, the clip member 5 has an upper plate 51 (upper plate portion), a receiving plate 52 (receiving plate portion), and a side plate 53. The clip member 5 receives the lower surface of the base end side upper inward extending piece 451 of the gutter configuring shape member 44 at the receiving plate 52, and is disposed on the upper surface of the extending plate portion 32 of the beam 3 at the upper plate 51. As a result, the clip member 5 sandwiches and holds the base end side upper inward extending piece 451 of the gutter configuring shape member 44 and the extending plate portion 32 of the beam 3 between the receiving plate 52 and the upper plate 51.

[0062] When viewed from above, the upper plate 51 and the receiving plate 52 are formed in an L-shape and are arranged overlapping in the vertical direction at the corner of the L-shape, with the tip side of the upper plate 51 being positioned on the upper surface of the extension plate portion 32 of the beam 3 and the tip side of the receiving plate 52 being positioned below the portion where the base end side upper inward extending piece 451 of the gutter constituent member 44 and the extension plate portion 32 of the beam 3 overlap.

[0063] The side plate 53 is formed in a plate shape that vertically connects one end in the width direction of the extending plate portion 32 of the beam 3 in the left-right direction of the upper plate 51 and the receiving plate 52. The side plate 53 is formed in a plate shape that has a width in the vertical direction and extends in the extension direction of the beam 3. As shown in Fig. 9, in the portion where the upper plate 51 and the receiving plate 52 overlap, an open space K that opens to the extending plate portion 32 side of the beam 3 is formed between the upper plate 51 and the receiving plate 52.

[0064] 8, the upper plate 51 is disposed on the upper surface of the extending plate portion 32 of the beam 3, and extends across the entire width of the extending plate portion 32 of the beam 3. The upper plate 51 is formed in a plate shape having a predetermined thickness. Since the upper plate 51 has a thickness, the side surface 51a on the tip side can block water flowing from the tip side toward the base end side of the extending plate portion 32 of the beam 3, and guide the water to the roof body side gutter component 40 side of the gutter component shape member 44.

[0065] The portion of the receiving plate 52 on the support 2 side is disposed below the portion where the base end side upper inward extending piece 451 of the gutter configuring shape member 44 and the extending plate portion 32 of the beam 3 overlap, and the portion on the tip side is disposed below the extending plate portion 32 of the beam 3. As a result, the receiving plate 52 supports the base end side upper inward extending piece 451 of the gutter configuring shape member 44 and the extending plate portion 32 of the beam 3 from below, while overlapping the base end side upper inward extending piece 451 of the gutter configuring shape member 44 and the extending plate portion 32 of the beam 3. Since the base end side upper inward extending piece 451 of the gutter configuring shape member 44 is supported by the receiving plate 52, the fixing strength is improved. Furthermore, the portion of receiving plate 52 opposite to support pillar 2 overlaps upper plate 51 in the vertical direction, and the portion on the support pillar 2 side does not overlap upper plate 51. A screw hole 521 is formed in the portion of receiving plate 52 on the support pillar 2 side that does not overlap upper plate 51. Here, the screw holes 521 of upper plate 51 and receiving plate 52 do not overlap vertically. The tip of a screw member 54 is screwed into the screw hole 521 and fixed.

[0066] When using the clip member 5 to fix the gutter constituent member 44 to the beam 3, the clip member 5 is moved so that the extension plate portion 32 of the beam 3 is inserted into the open space K formed at the corner of the clip member 5, and so that the portion of the receiving plate 52 on the pillar 2 side is inserted below the overlapping portion between the base end side upper inward extension piece 451 of the gutter constituent member 44 and the extension plate portion 32 of the beam 3. In this state, as shown in Fig. 10, the clip member 5 sandwiches the base end upper inward extending piece 451 of the gutter forming member 44 and the extending plate portion 32 of the beam 3 between the receiving plate 52 and the upper plate 51. Therefore, in a state where hands are released during construction, the gutter forming member 44 can be fixed to the beam 3 by fastening together the extending plate portion 32 of the beam 3, the base end upper inward extending piece 451 of the gutter forming member 44, and the receiving plate 52 of the clip member 5 with the screw member 54. In this case, the tip of the screw member 54 can be screwed into the screw hole 521 of the receiving plate 52 for fixing. As a result, the receiving plate 52 can fix the tip of the screw member 54 in the screw hole 521, and functions as a back plate.

[0067] 1, a pair of roof body side cover members 8 are attached to both left and right ends of the roof body 4. The pair of roof body side cover members 8 are arranged extending in the front-rear direction at both left and right ends of the elongated material 41. The pair of roof body side cover members 8 are arranged at both left and right ends of the roof body 4 so as to cover the sides of the elongated material 41. The pair of roof body side cover members 8 each extend along the inclination direction of the roof body 4, with the support pillar 2 side sloping downward.

[0068] The gap closing unit 7 will now be described. The terrace 1 of this embodiment is constructed as an independent type so that when subjected to loads due to wind pressure, snow accumulation, etc., the roof body 4 does not apply a load to the structure 10 even if the support pillars 2 vibrate or bend. For this reason, a gap is provided between the tip of the roof body 4 and the structure 10. In this embodiment, a gap closing unit 7 is arranged to close the gap between the tip of the roof body 4 and the structure 10.

[0069] As shown in Fig. 1, the gap sealant unit 7 is connected to the tip of the roof body 4 and extends in the left-right direction of the roof body 4. As shown in Figs. 11 and 12, the gap sealant unit 7 includes a gap sealant material 71 and a mounting frame body 72 (connecting member). In this embodiment, the gap sealant material 71 and the mounting frame body 72 are unitized as the gap sealant unit 7, and are attached to the roof body 4 after being assembled as the gap sealant unit 7.

[0070] As shown in Fig. 4, the gap closing material 71 is arranged to close the gap between the tip of the roof body 4 and the structure 10. The gap closing material 71 is formed of a highly elastic and shrinkable material such as rubber or soft synthetic resin. The base end side of the gap closing material 71 is attached to the tip of the roof body 4 via a mounting frame 72, and the tip side is arranged in a bent state in contact with the structure 10.

[0071] The gap sealant 71 extends at an upward incline toward the body 10, and has a tongue-shaped tip 711 formed on the tip side and a water cutting piece 712 formed on the base end side, as shown in Figures 11 and 12. An L-shaped engagement portion 713 and a T-shaped fitting portion 714 are formed on the underside of the base end side of the gap sealant 71. The T-shaped fitting portion 714 and the L-shaped engagement portion 713 are arranged in this order from the water cutting piece 712 side (base end side) toward the tip side. The mounting frame 72 is connected to the T-shaped fitting portion 714 and the L-shaped engagement portion 713 arranged on the underside of the base end side of the gap sealant 71.

[0072] A gap closing material 71 is attached to the mounting frame 72, and the mounting frame 72 with the gap closing material 71 attached is fixed to the upper surface of the tip of the roof body 4. The mounting frame 72 connects the tip of the roof body 4 and the gap closing material 71.

[0073] The mounting frame 72 is disposed on the upper part of the roof body 4 and fixed to the upper surface of the roof body 4. The mounting frame 72 has a first mounting frame 73 (first member) and multiple second mounting frames 74 (second members). Since the mounting frame 72 is disposed on the upper part of the roof body 4, it is difficult to see from below the roof body 4.

[0074] As shown in Figures 3 and 12, the first mounting frame 73 is formed in an elongated shape along the left-right direction in which the leading edge of the roof body 4 extends. The first mounting frame 73 is formed, for example, from an extruded aluminum material. Both ends of the first mounting frame 73 are located inside both ends of the gap blockage material 71 in the left-right direction. As a result, the first mounting frame 73 is difficult to see from the below of the roof body 4 at both ends of the roof body 4 in the left-right direction.

[0075] 11, the first mounting frame 73 is attached to a T-shaped fitting portion 714 that is arranged on the underside of the base end portion of the gap sealant 71 below the base end portion of the gap sealant 71. The first mounting frame 73 has a fitting groove frame 731 with a C-shaped cross section, a lower open frame 732 formed at the bottom of the fitting groove frame 731, and an extension piece 733 that extends toward the tip side from the side surfaces on the tip sides of the fitting groove frame 731 and the lower open frame 732.

[0076] The T-shaped fitting portion 714 of the gap closing material 71 fits into the fitting groove frame 731. The T-shaped fitting portion 714 fitted into the fitting groove frame 731 is fixed to the lower plate 731a of the fitting groove frame 731 as shown in FIG. 11 at one location on the center side in the left-right direction of the roof body 4 by a screw member 715 as shown in FIG. 3. The screw member 715 is moved from the lower side to the upper side, so that it is screwed in from the lower open frame 732 side. The screw head 715a of the screw member 715 is disposed on the lower surface of the lower plate 731a of the fitting groove frame 731, and the first mounting frame 73 is disposed on the upper surface of the roof body 4, so that it is not exposed to the outside and is difficult to be seen from the outside, improving the design.

[0077] The downward open frame 732 is formed to be open downward at the lower part of the fitting groove frame 731. An upper plate 732a of the downward open frame 732 and a lower plate 731a of the fitting groove frame 731 are a common member. A protruding piece 732b that protrudes toward the tip side is formed at the lower end part on the base end side of the downward open frame 732. The protruding piece 732b is engaged with a bent engaging part 741b of the second mounting frame 74 described later.

[0078] The extension piece 733 protrudes toward the tip side. The extension piece 733 is fixed to the second mounting frame 74, which will be described later.

[0079] As shown in Figs. 3 and 12, the second mounting frames 74 are arranged in a line at intervals in the longitudinal direction of the first mounting frame 73 along the left-right direction in which the leading edge of the roof body 4 extends. The second mounting frames 74 are formed of, for example, an aluminum material. The second mounting frames 74 can be attached by adjusting the intervals between each other. For example, in the case of interference with other members at the site where the gap closing unit 7 is installed, the second mounting frames 74 can be moved and installed, so that the degree of freedom in the arrangement of the second mounting frames 74 is improved, and the ability to respond at the site can be improved. In this embodiment, the second mounting frames 74 are arranged at positions that avoid the portion where the beam 3 is arranged, and are also arranged at positions that avoid the portion where the plate-shaped protruding portion 341 of the tongue-shaped member 34 connected to the beam 3 is arranged.

[0080] As shown in Figure 11, the second mounting frame 74 is attached to the first mounting frame 73 which is attached below the base end of the gap filler material 71, and is also attached to the L-shaped engagement portion 713 of the gap filler material 71 which is arranged on the underside of the gap filler material 71. As shown in FIG. 11, the second mounting frame 74 has a bottom plate 741, an L-shaped rising piece 742, and a return hook piece 744.

[0081] The bottom plate 741 is disposed along the upper surface of the roof body 4 on the base end side of the gap closing material 71, and extends from the tip side of the T-shaped fitting portion 714 to the base end side of the water cutting piece 712. The end portion on the base end side of the extension piece 733 is fixed to the upper surface of the roof body 4 by a screw member 741a.

[0082] A bent locking portion 741b is formed on the upper surface of the bottom plate 741. The bent locking portion 741b rises upward from the upper surface of the roof body 4, bends toward the base end at the upper end, and extends toward the base end. A protruding piece 732b of the lower open frame 732 of the first mounting frame 73 is locked to the bent locking portion 741b.

[0083] The L-shaped rising piece 742 is connected to the tip of the bottom plate 741, rises upward, bends at the upper end toward the tip, and extends toward the tip. The upper plate of the L-shaped rising piece 742 is fixed to the extension piece 733 of the first mounting frame 73 by the screw member 742a. ​​The screw member 742a is moved from the lower side to the upper side, and is screwed in from the lower side of the L-shaped rising piece 742. In this way, the first mounting frame 73 and the multiple second mounting frames 74 are fixed with the screw member 742a penetrating the first mounting frame 73 and the multiple second mounting frames 74 in the vertical direction, with the screw head 742b located at the lower part. The screw head 742b of the screw member 742a is located on the upper side of the roof body 4 when the gap blocker 71 is fixed between the first mounting frame 73 and the multiple second mounting frames 74. This allows the screw members 742a to be prevented from being exposed to the outside and therefore difficult to see from the outside, improving the design.

[0084] A locking projection 743 (locking portion) that protrudes toward the tip side is formed on the side surface of the tip side of the lower side of the rising portion of the L-shaped rising piece 742. The locking projection 743 is locked to the hook piece 423 of the tip side frame 42 that opens toward the base end side. Thereby, when the mounting frame body 72 is fixed to the upper surface of the roof body 4, by locking the locking projection 743 to the hook piece 423, it is possible to perform vertical positioning with respect to the tip side frame 42 and prevent rattling.

[0085] The return hook piece 744 is formed in a hook shape returning from the tip of the L-shaped rising piece 742 to the base end side. The return hook piece 744 extends from the tip of the L-shaped rising piece 742 toward the tip end side at an upward incline, bends at the upper end toward the base end side, and extends toward the base end side. The return hook piece 744 engages with the L-shaped engagement portion 713 of the gap closing material 71.

[0086] The mounting frame body 72 configured as above fixes the gap sealant 71 in place with the first mounting frame 73 and the plurality of second mounting frames 74 sandwiching the base end side portion of the gap sealant 71 therebetween.

[0087] Next, a construction method for the terrace 1 of this embodiment will be described with reference to Figs. 13 to 17, 9 and 12. Fig. 13 is a perspective view showing a state in which a plurality of long members 41 and a gap closing unit 7 are attached to a beam 3. Fig. 14 is a cross-sectional view showing a state in which a tip end side member 42 constituting the roof body 4 is attached to the beam 3. Fig. 15 is a cross-sectional view showing a state in which a gap closing unit 7 is attached to the tip end side member 42. Fig. 16 is a cross-sectional view showing a state in which an intermediate member 43 constituting the roof body 4 is attached to the beam 3. Fig. 17 is a cross-sectional view showing a state in which a gutter forming member 44 constituting the roof body 4 is attached to the beam 3.

[0088] Here, we will mainly explain the case where the roof body 4 is attached to the lower part of the beam 3 with the beam 3 connected to the support pillar 2. Specifically, as shown in Fig. 13, a plurality of long members 41 are installed in order from the tip end side to the base end side of the beam 3 on the underside of the extension plate part 32 of the beam 3.

[0089] In detail, first, the worker attaches the tip side profile 42 to the underside of the extension plate portion 32 of the beam 3 at the tip-most side of the roof body 4, as shown in FIG.

[0090] As shown in Figure 14, when attaching the tip side profile 42 to the beam 3, the worker hooks the hook piece 423 of the tip side profile 42 onto the plate-shaped protrusion 341 of the tongue-shaped member 34 provided on the tip side of the beam 3, thereby temporarily supporting and holding the tip side end (the end distal from the support 2) of the tip side profile 42 on the plate-shaped protrusion 341 of the tongue-shaped member 34 (temporary support process, holding stage).

[0091] This allows the worker to temporarily release his / her hands from the tip-side extrusion 42, so that even one worker can perform the work, improving the workability when attaching the tip-side extrusion 42 to the beam 3. With the tip-side end (end distal from the support 2) of the tip-side extrusion 42 temporarily supported and held by the plate-like protruding portion 341 of the tongue-shaped member 34, the worker moves the base-side end (end proximal to the support 2) of the tip-side extrusion 42 toward the beam 3 (moving process, moving stage). Then, in this state, the base-side end (end proximal to the support 2) of the tip-side extrusion 42 is fixed to the extending plate portion 32 of the beam 3 by the screw members 102 and 105 (fixing process, fixing stage). In the base end upper extension piece 427 of the tip side profile 42, the screw member 102 is moved from above, and the screw member 102 passes through the extension plate portion 32 of the beam 3 and the base end upper extension piece 427 of the tip side profile 42.The screw member 102 is then screwed into the back plate member 108 arranged below the base end upper extension piece 427 of the tip side profile 42, thereby fixing the tip side profile 42 to the beam 3.

[0092] Conventionally, when constructing a roof body with the tip facing the building wall (main structure), if a construction method was used in which multiple long materials were fixed in sequence from the base end of the beam to the tip end, there was no space for a worker to fit between the long materials already installed and the main structure at the tip end of the beam, making it difficult to construct the roof body.

[0093] In contrast, in the present invention, the tip side shape member 42 can be temporarily supported during construction of the roof body 4, so multiple long shape members 41 can be attached from the tip side of the beam 3 toward the base end. This makes it easy to construct the roof body 4, as the skeleton 10 is unlikely to get in the way, even if it is located at the tip side of the beam 3. Also, by hooking the hook piece 423 onto the tongue-shaped member 34, the tip side shape member 42 can be temporarily supported, so a worker can easily assemble the terrace 1 by himself.

[0094] Next, after attaching the tip side profile 42 and before attaching the adjacent intermediate profile 43, the worker attaches the gap closing unit 7 to the upper surface of the tip side profile 42 at the tip side of the roof body 4. If an attempt is made to attach the gap closing unit 7 after attaching the intermediate profile 43, the attached intermediate profile 43 will get in the way of the work of attaching the gap closing unit 7, making it difficult to attach the gap closing unit 7 to the roof body 4. In this embodiment, the gap closing unit 7 is installed after the tip side profile 42 is attached and before the adjacent intermediate profile 43 is attached, but this is not limited to this, and the gap closing unit 7 may be installed after attaching a number of intermediate profiles 43 that do not interfere with the work of installing the gap closing unit 7.

[0095] When attaching the gap closet unit 7 to the roof body 4, as shown in Fig. 12, the gap closet material 71 and the mounting frame body 72 (first mounting frame 73 and multiple second mounting frames 74) are connected and assembled in advance (connecting step), and the gap closet unit 7 is pre-unitized and assembled. Then, as shown in Fig. 15, the assembled gap closet unit 7 is placed on the upper surface of the roof body 4 with the locking projections 743 locked to the hook pieces 423 of the tip-side profile 42. In this state, the multiple second mounting frames 74 are fixed to the upper surface of the roof body 4 with multiple screw members 741a (fixing step), thereby allowing the gap closet unit 7 to be attached to the upper surface of the roof body 4. Here, the screw members 715 and 742a used when assembling the gap sealing material 71 and the mounting frame body 72 (the first mounting frame 73 and the multiple second mounting frames 74) are attached from the bottom, and when the gap sealing unit 7 is placed on the upper surface of the roof body 4, they are difficult to see from below.

[0096] Next, as shown in FIG. 16, the worker attaches an intermediate extrusion member 43 adjacent to the base end side of the tip end side extrusion member 42 attached to the tip end side. 16, when attaching the intermediate member 43 to the beam 3 next to the base end side of the tip-side member 42, the worker temporarily places the intermediate member 43 below the beam 3 by hooking the return hook piece 435b of the hook extension piece 435 of the intermediate member 43 to the hook engagement portion 428a of the tip-side member 42 attached to the beam 3. This allows the worker to temporarily release his / her hands from the intermediate member 43, so that the work can be performed by a single worker, and the workability when attaching the intermediate member 43 to the beam 3 can be improved.

[0097] Thereafter, with the hook extension piece 435 of the intermediate shape member 43 hooked to the hook engagement portion 428a of the tip side shape member 42, the intermediate shape member 43 is rotated about the return hook piece 435b (and the hook engagement portion 428a) of the hook extension piece 435, thereby arranging the intermediate shape member 43 at the mounting position (arrangement step). This allows the intermediate shape member 43 to be easily moved from the temporary placement state to the mounting position, improving the workability when mounting the intermediate shape member 43 to the beam 3. Also, by simply hooking the return hook piece 435b to the hook engagement portion 428a and rotating, the long shape member 41 can be arranged at the mounting position to the beam 3. This improves the workability when constructing the roof body 4.

[0098] Next, the worker fixes the intermediate extrusion member 43 to the extending plate portion 32 of the beam 3 with the screw member 102. In the base end side upper extending piece 437 of the intermediate extrusion member 43, the screw member 102 is moved from above, and the screw member 102 penetrates through the extending plate portion 32 of the beam 3 and the base end side upper extending piece 437 of the intermediate extrusion member 43. The screw member 102 is then screwed into the back plate member 108 arranged below the base end side upper extending piece 437 of the intermediate extrusion member 43, whereby the tip end side extrusion member 42 is fixed to the beam 3. Here, the base end side of the intermediate extrusion 43 is engaged with the hook extension piece 435 of the intermediate extrusion 43 in a hooked state on the hook engagement portion 428a of the tip end side extrusion 42 without being fixed with a screw member. Therefore, the intermediate extrusion 43 can be fixed to the beam 3 by fixing only the base end side of the intermediate extrusion 43 with the screw member 102. This improves the workability when attaching the tip end side extrusion 42 to the beam 3.

[0099] Next, adjacent to the base end side of the intermediate extrusion member 43 attached to the beam 3, multiple intermediate extrusion members 43 are attached in sequence from the tip end side to the base end side of the roof body 4. Specifically, multiple intermediate extrusion members 43 are temporarily placed in sequence from the base end side of the roof body 4, rotated, and fixed with the screw members 101, and this process is repeated. These methods are similar to those for attaching the intermediate extrusion members 43 adjacent to the tip end side extrusion members 42 described above, and therefore will not be described.

[0100] Next, after attaching the multiple intermediate shapes 43 to the beams 3, a gutter-forming shape member 44 is attached next to the intermediate shapes 43 on the base end side of the roof body 4, as shown in Fig. 17. When attaching the gutter-forming shape member 44, the gutter-forming shape member 44 is rotated about the return hook piece 445b (and the hook engagement portion 428a) of the hook extension piece 445 with the hook extension piece 445 hooked on the hook engagement portion 438a of the intermediate shape member 43, thereby arranging the gutter-forming shape member 44 at the attachment position (arrangement process).

[0101] After the gutter-forming member 44 is placed in the mounting position, the gutter-forming member 44 is fixed to the extending plate portion 32 of the beam 3 using the clip member 5, as shown in Fig. 9. When fixing the gutter-forming member 44 to the beam 3 using the clip member 5, the clip member 5 is moved so that the extending plate portion 32 of the beam 3 is inserted into the open space K formed at the corner of the clip member 5, and the portion of the support plate 52 on the support column 2 side is inserted below the portion where the base end upper inward extending piece 451 of the gutter-forming member 44 and the extending plate portion 32 of the beam 3 overlap.

[0102] In this state, the clip member 5 sandwiches and holds the base end upper inward extending piece 451 of the gutter configuring member 44 and the extending plate portion 32 of the beam 3 between the receiving plate 52 and the upper plate 51 (holding process). Then, the screw member 54 is passed through in the vertical direction to fasten together the extending plate portion 32 of the beam 3, the base end upper inward extending piece 451 of the gutter configuring member 44, and the receiving plate 52 of the clip member 5, thereby fixing the base end side of the gutter configuring member 44 to the beam 3 (fixing process). Here, the gutter constituent member 44 is formed of a solid material with no hollow portion and has an open upper side, so that during construction it opens up due to the pressure of the long shape member 41 and its packing, etc., making it difficult to align the screw hole positions. In contrast, by temporarily fastening it using the clip member 5, it becomes easier to align the screw hole positions, improving the workability when attaching the gutter constituent member 44 to the beam 3. Furthermore, by using the clip member 5, the worker can release his / her hands from the gutter-forming shape member 44, so that the work can be performed by a single worker, improving the workability when attaching the gutter-forming shape member 44 to the beam 3. Furthermore, the extension plate portion 32 of the beam 3, the base end side upper inward extending piece 451 of the gutter-forming shape member 44, and the receiving plate 52 of the clip member 5 are fastened together and fixed by the screw member 54, improving the attachment strength.

[0103] The terrace 1 of the present embodiment described above provides the following advantages. The terrace 1 of this embodiment comprises a roof body 4 whose tip is disposed opposite the structure 10, a gap sealing material 71 that seals the gap between the tip of the roof body 4 and the structure 10, and a mounting frame body 72 that connects the tip of the roof body 4 and the gap sealing material 71, the mounting frame body 72 being disposed on the upper part of the roof body 4. Therefore, the mounting frame body 72 is difficult to see from below the roof body 4. This allows the design of the terrace 1 that is provided with the gap sealing material 71 to be improved.

[0104] Furthermore, in this embodiment, a mounting frame 72 is connected to the base end side of the gap sealing material 71, and the mounting frame 72 is fixed to the upper surface of the roof body 4. In this way, with a simple configuration in which the mounting frame 72 is fixed to the upper surface of the roof body 4, it is possible to achieve the effect that the mounting frame 72 is difficult to see from below the roof body 4.

[0105] Furthermore, in this embodiment, the mounting frame 72 has a locking projection 743 that can be locked to the hook piece 423 provided on the tip side of the upper surface of the roof body 4. As a result, when the mounting frame 72 is fixed to the upper surface of the roof body 4, the locking projection 743 locks onto the hook piece 423, making it possible to perform vertical positioning with respect to the tip side profile 42 and prevent rattling.

[0106] In this embodiment, the mounting frame 72 has a first mounting frame 73 formed in an elongated shape along the direction in which the leading edge of the roof body 4 extends, and a plurality of second mounting frames 74 arranged in a row at intervals along the longitudinal direction of the first mounting frame 73 along the direction in which the leading edge of the roof body 4 extends, and the mounting frame 72 fixes the gap sealing material 71 in a state in which the first mounting frame 73 and the plurality of second mounting frames 74 sandwich the base end side portion of the gap sealing material 71. As a result, the mounting frame 72 is configured to include two frames, the first mounting frame 73 and the second mounting frame 74, and therefore the base end side portion of the gap sealing material 71 can be sandwiched, and the gap sealing material 71 can be firmly held. Also, the plurality of second mounting frames 74 can be attached by adjusting the intervals between them. For example, when installing the gap sealing unit 7 at a site, if there is interference with other components, the multiple second mounting frames 74 can be moved and installed, thereby improving the freedom of positioning of the second mounting frames 74 and improving response capabilities at the site.

[0107] In this embodiment, the first mounting frame 73 and the second mounting frame 74 are fixed by screw members 742a that penetrate the first mounting frame 73 and the second mounting frame 74 in the vertical direction and have screw heads 742b disposed at the bottom, and the screw heads 742b of the screw members 742a are disposed on the upper side of the roof body 4 when the gap sealant 71 is fixed between the first mounting frame 73 and the second mounting frame 74. Therefore, the screw heads 742b of the screw members 742a are disposed on the upper side of the roof body 4 when the gap sealant 71 is fixed between the first mounting frame 73 and the multiple second mounting frames 74. As a result, the screw members 742a are not exposed to the outside and are difficult to see from the outside, improving the design.

[0108] Moreover, this embodiment further includes a support 2 and a beam 3 connected to the support 2, with its base end disposed on the support 2 side and extending from the base end to its tip end, and the second mounting frame 74 is disposed at a position avoiding the beam 3. Therefore, particularly in the case of a suspended terrace 1 in which the beam 3 is disposed on the upper part of the roof body 4, the second mounting frame 74 can safely hold the gap sealing material 71 by fixing the second mounting frame 74 at a position avoiding the beam 3.

[0109] Furthermore, the construction method for the terrace 1 of this embodiment includes the step of connecting the mounting frame body 72 and the gap sealant 71, and the step of fixing the connected mounting frame body 72 and gap sealant 71 to the upper surface of the roof body 4. This makes it possible to integrate the mounting frame body 72 and the gap sealant 71 and fix the integrated mounting frame body 72 and gap sealant 71 to the upper surface of the roof body 4, making the installation work easy.

[0110] While one preferred embodiment of the terrace (roof structure) of the present invention has been described above, the present invention is not limited to the above-described embodiment and can be modified as appropriate. For example, in the above embodiment, the plurality of long members 41 are directly fixed and connected to the beam 3 by the screw members 101, but the present invention is not limited to this. For example, the plurality of long members 41 may be connected to the beam 3 via a support member or the like.

[0111] In the above embodiment, the long material 41 has a hollow structure having a hollow portion, but the present invention is not limited to this, and a solid material having no hollow portion or a material having a structure combining a plurality of solid materials may be used. Also, the number of hollow portions in the hollow structure of the long material 41 is not limited.

[0112] In the above embodiment, the clip member 5 is used for the gutter component member 44 that is fixed last when multiple long members 41 are sequentially fixed from the tip end side to the base end side of the roof body 4, but this is not limited to this. Here, a technique for sequentially fixing multiple long members from the base end side to the tip end side of the roof body is known (see, for example, JP 2018-123647 A). The clip member 5 may be used for the gutter component member that is fixed first when multiple long members are sequentially fixed from the base end side to the tip end side of the roof body. In this case, it is preferable that the gutter component member has a hook structure at the end opposite to the end clamped by the clip member 5 in the width direction (see, for example, JP 2018-123647 A [Figure 12], etc.).

[0113] In the above embodiment, the roof structure is configured as a suspended structure in which the roof body is suspended from the lower part of the beam, but the structure is not limited to a suspended structure when the gap closing material 71 is provided. The gap closing member may be provided on a roof structure having a resting structure in which the roof body is placed on the upper part of the beam. [Explanation of symbols]
