[0012] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0013] As shown in Figures 1 to 3, in one embodiment of the present invention, roof panel 1 is a unit type having skeletal members 2, deck plate 3, heat insulating material 4, waterproof sheet 5, frame group 6, and sound absorbing material 7, and multiple units can be attached side by side to a roof framework 8 as shown in Figures 8 to 10. A construction method in which unit type roof panel 1 assembled on the ground is lifted and installed on the roof as shown in Figure 7 reduces the amount of work on the roof, enabling efficient and safe construction.

[0014] As shown in Figures 1 to 3, roof panel 1 has a skeletal member 2, deck plate 3, heat insulating material 4, and waterproof sheet 5, in this order, facing upward, and also has the above-mentioned skeletal member 2, frame group 6, and sound absorbing material 7, in this order, facing downward. In other words, deck plate 3, arranged above skeletal member 2, is attached, and heat insulating material 4, arranged above deck plate 3, is attached, and waterproof sheet 5, arranged above heat insulating material 4, is attached. Furthermore, frame group 6, arranged below skeletal member 2, is attached, and sound absorbing material 7, arranged below frame group 6, is attached. The order of attachment will be described later.

[0015] The waterproof sheet 5 has a two-layer structure consisting of a top layer sheet 9 and a bottom layer sheet 10. The frame group 6 consists of multiple frames 6a (four in the illustrated example). The number of frames 6a is not limited to four and may be any number other than four. The deck plate 3, the heat insulating material 4, the top layer sheet 9, the bottom layer sheet 10, the skeletal member 2, the frames 6a, and the heat insulating material 4 may each be constructed by assembling multiple members.

[0016] The roof panel 1 has snow guard pads 11 to which horizontally extending rod-shaped snow guard members (not shown) can be attached to prevent snow from sliding off a sloping, flat roof. The snow guard pads 11 are attached to the upper surface of the framework member 2, and the deck plate 3, heat insulating material 4, and waterproof sheet 5 are installed so as to avoid the snow guard pad 11. There are no particular restrictions on the method for attaching the snow guard pads 11 to the framework member 2, and for example, fixing devices such as rivets, bolts, and screws, or welding can be used.

[0017] The framework member 2 consists of one vertical member 2a and multiple (five in the illustrated example) horizontal members 2b. The number of horizontal members 2b is not limited to five and may be any number other than five. The vertical member 2a extends vertically, and the multiple horizontal members 2b are arranged vertically and horizontally, perpendicular to the vertical direction. The horizontal direction coincides with the horizontal direction whether the panel is installed on the ground or on a roof. The vertical direction usually coincides with the horizontal direction when installed on the ground, but when installed on a roof, coincides with the direction perpendicular to the horizontal direction in a plane parallel to the sloping roof (hereinafter also referred to as the tilt direction). The direction perpendicular to both the vertical and horizontal directions is also referred to as the panel thickness direction.

[0018] The vertical member 2a and the multiple horizontal members 2b are arranged at the same height in the panel thickness direction. The vertical member 2a and the horizontal members 2b are each composed of H-shaped steel beams arranged to form a horizontal H shape. Note that the orientation of the H-shaped steel beams that make up the vertical member 2a and the horizontal members 2b is not limited to this. The vertical member 2a and the horizontal members 2b may also be composed of materials other than H-shaped steel. A single vertical member 2a and multiple horizontal members 2b may also be arranged at different heights and interconnected.

[0019] The vertical members 2a are connected to each horizontal member 2b at the longitudinal center of the horizontal member 2b. The longitudinal lengths of the multiple horizontal members 2b are equal to each other. The vertical members 2a are arranged so that they do not extend beyond the two horizontal members 2b positioned at the outermost positions in the longitudinal direction. There are no particular limitations on the method for attaching the vertical members 2a to the horizontal members 2b, and for example, fasteners such as rivets, bolts, and screws, or welding can be used.

[0020] The snow guard pad 11 is disposed in the center of the frame member 2 (at the intersection of the vertical member 2a and the horizontal member 2b disposed in the center) when viewed in the panel thickness direction. The location of the snow guard pad 11 can be set as appropriate.

[0021] The frame 6a is made of a C-shaped steel beam with four corners. However, the frame 6a may be made of a material other than a C-shaped steel beam. The four frames 6a constituting the frame group 6 are arranged side by side in the horizontal direction and each extends in the vertical direction. The frames 6a are attached to each of the horizontal members 2b. There are no particular restrictions on the method for attaching the frames 6a to the horizontal members 2b, and for example, fasteners such as rivets, bolts, and screws, or welding can be used. The frames 6a are positioned so that they do not extend beyond the two horizontal members 2b positioned outermost in the vertical direction.

[0022] The deck plate 3 is a corrugated plate made of metal such as alloy steel that has a rectangular wave shape when viewed in the vertical direction. The deck plate 3 is attached to the upper surface of each cross member 2b. There are no particular restrictions on the method for attaching the deck plate 3 to the cross members 2b, and fasteners such as rivets, bolts, and screws can be used. The deck plate 3 is positioned so that it does not extend beyond the two cross members 2b that are positioned outermost in the vertical direction. The horizontal width of the deck plate 3 is smaller than the horizontal width of the skeletal members 2, and the deck plate 3 is positioned laterally inward of both horizontal ends of the skeletal members 2.

[0023] The insulating material 4 is a plate made of a material with excellent insulating properties, such as a wood wool cement board or urethane foam. The insulating material 4 is attached to the upper surface of the deck plate 3. There are no particular limitations on the method for attaching the insulating material 4 to the deck plate 3, and fasteners such as rivets, bolts, and screws can be used, for example. The vertical width of the insulating material 4 is smaller than the vertical width of the deck plate 3, and the insulating material 4 is positioned vertically inward from both vertical ends of the deck plate 3. Furthermore, the horizontal width of the insulating material 4 is smaller than the horizontal width of the deck plate 3, and the insulating material 4 is positioned horizontally inward from both horizontal ends of the deck plate 3.

[0024] The lower layer sheet 10 is a sheet material that includes, for example, an asphalt layer and has excellent waterproof properties. The lower layer sheet 10 is attached to the upper surface of the insulating material 4. The method for attaching the lower layer sheet 10 to the insulating material 4 is not particularly limited, and for example, the lower layer sheet 10 can be attached to the insulating material 4 via an adhesive layer or glue that is previously provided on the lower surface of the lower layer sheet 10. The lower layer sheet 10 is arranged so as to cover the entire upper surface of the insulating material 4. However, the arrangement of the lower layer sheet 10 is not limited to this, and for example, the outer peripheral edge 10a of the lower layer sheet 10 may be arranged inside the outer peripheral edge of the insulating material 4 around the entire circumference.

[0025] The lower layer sheet 10 is made up of a plurality of strip-shaped sheets arranged side by side in the horizontal direction, with two adjacent strip-shaped sheets arranged so as to overlap each other at the seam. The strip-shaped sheets that make up the lower layer sheet 10 may also be made up of a plurality of sheet materials arranged side by side in the vertical direction, with two adjacent sheet materials arranged so as to overlap each other at the seam. The lower layer sheet 10 may also be made up of a single sheet material.

[0026] The top layer sheet 9 is a sheet material that includes, for example, an asphalt layer and has excellent waterproof properties. The material and layer structure of the top layer sheet 9 may be different from or the same as those of the lower layer sheet 10. The top layer sheet 9 is attached to the upper surface of the lower layer sheet 10. The method for attaching the top layer sheet 9 to the lower layer sheet 10 is not particularly limited, and for example, the top layer sheet 9 can be attached to the lower layer sheet 10 via an adhesive layer or glue that is provided in advance on the underside of the top layer sheet 9. The outer peripheral edge 9a of the top layer sheet 9 is positioned inside the outer peripheral edge 10a of the lower layer sheet 10 around the entire periphery.

[0027] The top layer sheet 9 is made up of multiple strip-shaped sheets arranged side by side in the horizontal direction, with two adjacent strip-shaped sheets overlapping each other at the seam. The strip-shaped sheets that make up the top layer sheet 9 may also be made up of multiple sheet materials arranged side by side in the vertical direction, with two adjacent sheet materials overlapping each other at the seam. The top layer sheet 9 may also be made up of a single sheet material.

[0028] The sound-absorbing material 7 is a plate material made of, for example, polyvinyl chloride or glass nonwoven fabric. As shown in Figures 1 and 4, the sound-absorbing material 7 is attached to each frame 6a. There are no particular restrictions on the method for attaching the sound-absorbing material 7 to the frame 6a, and fasteners such as rivets, bolts, and screws can be used. Among these, the attachment method using L-angle members 12, hanging bolts 13, disk members 14, and nuts 15 as shown in the figure is preferred from the standpoints of space saving and ease of attachment.

[0029] The L-angle member 12 is arranged so as to form an L-shape when viewed vertically, and the side wall portion 12a of the L-angle member 12 is fixed to the outer surface of the side wall portion of the frame 6a with, for example, screws 16. Furthermore, with a hanging bolt 13 passed through a hole that penetrates the bottom wall portion 12b of the L-angle member 12 in the panel thickness direction, nuts 15 are placed on the upper and lower surfaces of the bottom wall portion 12b, and the hanging bolt 13 is fixed to the bottom wall portion 12b with the nuts 15. The sound-absorbing material 7 and the disk material 14 each have a hole through which the lower end of the hanging bolt 13 fixed as described above is passed. The sound-absorbing material 7 and the disk material 14 are placed on the hanging bolt 13 in this order via the holes, and the sound-absorbing material 7 can be attached to the frame 6a by fastening the nuts 15 to the hanging bolt 13.

[0030] The work of installing this sound-absorbing material 7 can be carried out, for example, with the roof panel 1, on which all parts except for the sound-absorbing material 7 have been installed, placed on a holding stand 17 installed on the ground, as shown in Figure 5. In other words, the holding stand 17 can hold the roof panel 1 at a height suitable for a worker to install the sound-absorbing material 7 while standing underneath the roof panel 1.

[0031] Furthermore, from the viewpoint of work efficiency, it is preferable to store a certain number of roof panels 1 that have been assembled with the sound-absorbing material 7 until they are hoisted onto the roof. To achieve this, it is preferable to use a stacking stand 18, as shown in Figure 6, on which multiple roof panels 1 can be stacked vertically, in order to save space.

[0032] Once assembled, the roof panel 1 is lifted onto the roof by a crane or the like, as shown in Figure 7, and attached to the roof framework 8. When lifting, it is preferable to lift the roof panel 1 using a jig 19 as shown in the figure that can be attached to and detached from the roof panel 1.

[0033] The jig 19 includes a first frame 19a extending vertically and removably attached to one horizontal end of each horizontal member 2b, and a second frame 19b extending vertically and removably attached to the other horizontal end of each horizontal member 2b. The first frame 19a and the second frame 19b are each composed of H-shaped steel beams arranged to form a horizontal H-shape. Note that the first frame 19a and the second frame 19b may be composed of materials other than H-shaped steel beams. The method for attaching the first frame 19a and the second frame 19b to the horizontal members 2b is not particularly limited; for example, detachable fasteners such as bolts can be used. The use of the first frame 19a and the second frame 19b reinforces the torsional rigidity of the roof panel 1, stabilizing its posture during lifting, and improving safety.

[0034] From the viewpoint of increasing torsional rigidity, it is preferable that the jig 19 further includes one or more bridging members 19c spanning between the first aggregate 19a and the second aggregate 19b. For example, the jig 19 includes a plurality of bridging members 19c for fixing the cord-like bodies 20, each having fixing portions at both lateral ends to which the cord-like bodies 20 for lifting are fixed. Such a configuration makes it easier to further improve work efficiency.

[0035] As shown in Figures 8 to 10, on the roof, an installation process is carried out in which a plurality of roof panels 1 are lined up and installed on the roof framework 8, and a post-installation process is carried out after the installation process in which the joints of the plurality of roof panels 1 are covered with a joint waterproof sheet 21. In other words, the roof installation method of this embodiment includes a preparation process in which the roof panels 1 are assembled on the ground, followed by the above-mentioned installation process and post-installation process. Figures 8 to 10 show the components installed in the post-installation process in shaded areas.

[0036] In the installation process, multiple roof panels 1 are arranged horizontally and in the inclined direction on the roof framework 8, and then attached to the roof framework 8. In this embodiment, the framework members 2 of the roof panel 1 are configured so that both lateral ends of each cross member 2b are free ends, so that when the roof panel 1 is placed on the roof framework 8, the framework members 2 can flex and deform to follow the framework 8, thereby enabling a smooth installation operation.

[0037] In the post-construction process, as shown in Figure 8, a joint deck plate 22 is placed between the deck plates 3 of two horizontally adjacent roof panels 1 and attached to the upper surface of the cross member 2b. Also in the post-construction process, a joint insulation material 23 is attached to the upper surface of the joint deck plate 22, a joint lower layer sheet 24 is attached to the upper surface of the joint insulation material 23, and a joint upper layer sheet 25 is attached to the upper surface of the joint lower layer sheet 24.

[0038] At this time, both lateral edge portions 24a of the joint lower layer sheet 24 are attached so as to overlap the upper surface of the lateral edge portion of the lower layer sheet 10 of the adjacent roof panel 1. At this time, because the top layer sheet 9 of the roof panel 1 is positioned inside the outer peripheral edge portion 10a of the lower layer sheet 10, both lateral edge portions 24a of the joint lower layer sheet 24 can be attached so as to overlap the upper surface of the lateral edge portion of the lower layer sheet 10 of the adjacent roof panel 1. Also, both lateral edge portions of the joint top layer sheet 25 are attached so as to overlap the upper surface of the lateral edge portion of the top layer sheet 9 of the adjacent roof panel 1. By positioning and attaching the joint waterproof sheet 21 consisting of the joint lower layer sheet 24 and the joint top layer sheet 25 as described above, a finish with excellent appearance and waterproofness can be achieved.

[0039] 9 and 10, in the post-construction process, joint insulation 23 is placed between the insulation materials 4 of two roof panels 1 adjacent to each other in the tilt direction, and attached to the upper surface of the deck plate 3. Also in the post-construction process, joint insulation 23 is attached to the upper surface of the joint deck plate 22, joint lower layer sheet 24 is attached to the upper surface of joint insulation 23, and joint upper layer sheet 25 is attached to the upper surface of joint lower layer sheet 24.

[0040] At this time, both vertical edge portions 24b of the joint lower layer sheet 24 are attached so as to overlap the upper surface of the vertical edge portion of the lower layer sheet 10 of the adjacent roof panel 1. Since the top layer sheet 9 of the roof panel 1 is positioned inside the outer peripheral edge portion 10a of the lower layer sheet 10, both vertical edge portions 24b of the joint lower layer sheet 24 can be attached so as to overlap the upper surface of the vertical edge portion of the lower layer sheet 10 of the adjacent roof panel 1. Furthermore, both vertical edge portions of the joint top layer sheet 25 are attached so as to overlap the vertical edge portion of the top layer sheet 9 of the adjacent roof panel 1. In consideration of waterproofing, the upper edge portion is positioned so as to overlap from above. By positioning and attaching the joint waterproof sheet 21 as described above, a finish with excellent appearance and waterproofing can be achieved.

[0041] According to this embodiment, most of the construction of the roof for thermal insulation, waterproofing and sound absorption can be carried out easily and safely on the ground.

[0042] The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and scope of the present invention.

[0043] Therefore, the roof panel 1 of the above-mentioned embodiment can be modified as long as it is a unit-type roof panel 1 that can be attached to the roof frame 8 and has a skeletal member 2, deck plate 3, insulation material 4 and waterproof sheet 5 facing upward in this order.

[0044] For example, the skeletal member 2 is not limited to a configuration consisting of one vertical member 2a and multiple horizontal members 2b, but may also be a configuration consisting of multiple vertical members 2a arranged in the horizontal direction and multiple horizontal members 2b arranged in the vertical direction. In this case, it is preferable that both horizontal ends of each horizontal member 2b are arranged outward from the two horizontally outermost vertical members 2a. In other words, the skeletal member 2 may consist of one or multiple vertical members 2a, but in either case, it is preferable that both horizontal ends of each horizontal member 2b are free ends. Note that the skeletal member 2 is not limited to a configuration in which both horizontal ends of each horizontal member 2b are free ends, and the skeletal member 2 may be configured, for example, in the shape of a rectangular frame.

[0045] Furthermore, the top layer sheet 9 is not limited to being arranged inside the outer peripheral edge 10a of the lower layer sheet 10, and may be arranged, for example, to cover the entire upper surface of the lower layer sheet 10. The waterproof sheet 5 is not limited to a two-layer structure consisting of the top layer sheet 9 and the lower layer sheet 10, and may be, for example, a single-layer structure. The roof panel 1 is not limited to being arranged with a frame 6a and sound-absorbing material 7. The roof panel 1 is not limited to being arranged to form a sloped portion of the roof. Note that the roof panel 1 may be arranged with reinforcing plates or the like interposed in addition to the above-mentioned components, as appropriate.

[0046] It should be noted that the roof panel 1 of the above-described embodiment is preferably a roof panel 1 having the framework member 2, the frame 6a, and the sound-absorbing material 7 facing downward in this order in the above configuration.

[0047] In the above-described embodiment, the roof panel 1 is preferably configured such that the waterproof sheet 5 is made up of multiple layers including a top layer sheet 9 and a bottom layer sheet 10, and the top layer sheet 9 is positioned inside the outer peripheral edge portion 10a of the bottom layer sheet 10.

[0048] It is preferable that the roof construction method of the above-mentioned embodiment is a roof construction method that includes an installation process of attaching multiple roof panels 1 in a line to the roof frame 8, and a post-installation process of covering the joints of the multiple roof panels 1 with a joint waterproof sheet.
