FIG. 3 is a cross-sectional view of the roof including the cross section AA of FIG. 2. 3 is a cross-sectional view of the roof including the cross section BB of FIG. 2.

Embodiments of the present invention will be described below with reference to the drawings.

As shown in Figure 1, in one embodiment of the present invention, the roof panel 1 is a modular type that can be attached to the roof framework 2. By using a modular roof panel 1, part of the roof construction can be performed on the ground, thereby facilitating roof construction.

The roof panel 1 has three or more (five in this embodiment) rib members 3 arranged in a predetermined direction (also referred to as the vertical direction for ease of explanation), and connecting members 4 that connect adjacent rib members 3 with pin joints. In this embodiment, a total of four connecting members 4 are provided, one between each pair of adjacent rib members 3.

The frame members 3 extend linearly in a direction (also referred to as the horizontal direction for convenience of explanation) perpendicular to both the vertical direction and the direction perpendicular to the panel (also referred to as the panel thickness direction for convenience of explanation). The frame members 3 are made of H-shaped steel and have a beam portion 3a and two flange portions 3b connected to both ends of the beam portion 3a in the panel thickness direction. All frame members 3 are the same length, and are all arranged so that they are aligned straight in the vertical direction.

The connecting members 4 extend linearly in the vertical direction. They are made of channel steel and are arranged with their openings facing horizontally. All connecting members 4 are the same length, and are arranged so that they are aligned vertically at positions corresponding to the centers of the frame members 3 in the horizontal direction.

The connecting member 4 is connected to adjacent frame members 3 in the vertical direction by a pin joint. That is, both vertical ends of the connecting member 4 are pin-joined to the frame member 3 facing that end. In this embodiment, the connecting member 4 is joined to the beam portion 3a of the frame member 3 without being joined to the flange portion 3b of the frame member 3, using a pin joint. The joining method for joining the connecting member 4 to the beam portion 3a is not particularly limited; for example, it may be joined using fasteners such as bolts or rivets via a joint member such as a splice plate, or it may be joined by welding with or without a joint member.

The connecting members 4 use pin joints to connect adjacent frame members 3 in the vertical direction so that they can move relative to each other in a direction intersecting the roof panel 1. Note that the connecting members 4 are not limited to channel steel, and may be made of, for example, H-shaped steel.

As shown in Figures 2 to 4, each frame member 3 is placed on and attached to the roof framework 2. More specifically, both ends of each frame member 3 are placed on and attached to the receiving portions 2a of the roof framework 2. In this embodiment, the roof forms a sloped portion, and the roof panel 1 constitutes the sloped portion. More specifically, the frame members 3 are arranged so that they extend horizontally.

As shown in FIG. 1, the roof panel 1 further has two braces 5 between the rib member 3 located at the top when attached to the roof frame 2 and the rib member 3 adjacent to that rib member 3. For ease of explanation, the rib member 3 located at the top when attached to the roof frame 2 is also referred to as the first rib member 3, and the rib members 3 located successively downward are also referred to as the second rib member 3, the third rib member 3, the fourth rib member 3, and the fifth rib member 3. One brace 5 extends linearly from the end of the connecting member 4 closest to the second rib member 3 to one lateral end of the first rib member 3, and the other brace 5 extends linearly from the end of the connecting member 4 closest to the second rib member 3 to the other end of the first rib member 3. These braces 5 reinforce the first rib member 3 and the connecting member 4 connected to it, which are subject to the greatest load before being installed on the roof frame 2.

As shown in Figure 2, the roof panel 1 further includes a deck plate 7 that is positioned above the skeletal members 6 in the panel thickness direction and attached to them. The skeletal members 6 consist of frame members 3, connecting members 4, and braces 5; more specifically, five frame members 3, four connecting members 4, and two braces 5. The deck plate 7 is a corrugated metal plate made of alloy steel or other metal that has a rectangular wave shape when viewed vertically. The deck plate 7 is attached to the upper surface of each frame member 3 in the panel thickness direction. The method for attaching the deck plate 7 to the frame members 3 is not particularly limited; for example, fasteners such as bolts or rivets can be used. The deck plate 7 is positioned so that it does not extend beyond the two outermost frame members 3 in the vertical direction. The horizontal width of the deck plate 7 is smaller than that of the skeletal members 6, and the deck plate 7 is positioned laterally inward of both horizontal ends of the skeletal members 6.

In this embodiment, the deck plate 7 is composed of a first component 7a that is positioned so as to straddle the first and third frame members 3 and is attached to the first, second, and third frame members 3, and a second component 7b that is positioned so as to straddle the third and fourth frame members 3 and is attached to the third, fourth, and fifth frame members 3. The first component 7a and the second component 7b are formed separately from each other. The first component 7a and the second component 7b may also be formed integrally.

The roof panel 1 may further include any optional components that are layered and attached to the upper side of the deck plate 7 in the panel thickness direction. Examples of such components include insulation material and waterproof sheet material, which may be layered in sequence. The roof panel 1 may further include any optional components that are layered and attached to the lower side of the frame member 6 in the panel thickness direction. Examples of such components include sound-absorbing material.

As shown in Figure 1, one horizontal end of each frame member 3 of the roof panel 1 is configured to allow one vertically extending temporary beam 8 to be detachably attached, and the other end is configured to allow another vertically extending temporary beam 8 to be detachably attached. The temporary beams 8 may be configured from structural steel such as H-shaped steel or channel steel. There are no particular limitations on the method for detachably attaching the temporary beams 8 to the frame members 3, and fasteners such as bolts can be used, for example.

The roof construction method using the roof panel 1 includes a transport step in which the roof panel 1 is transported onto the roof framework 2, and an attachment step in which the roof panel 1 is attached to the roof framework 2. The transport step is preferably carried out by transporting the roof panel 1 onto the roof framework 2 in a reinforced state, with one end of each of the frame members 3 of the roof panel 1 connected to one temporary beam 8 and the other end to another temporary beam 8. In this case, the attachment step can be carried out by, for example, sequentially removing each frame member 3 from the two temporary beams 8 and then placing and attaching it to the receiving portion 2a of the roof framework 2, as shown in Figures 3 and 4.

At this time, all adjacent bone members 3 can move relative to each other in the vertical direction due to the pin joints described above. Therefore, even if the positions of the bone members 3 and the receiving portions 2a are slightly offset vertically from their designed positions, each bone member 3 can be displaced to fit into the receiving portion 2a and placed on the receiving portion 2a, allowing for easy attachment. Furthermore, because all adjacent bone members 3 are connected at their horizontal centers by the connecting members 4, adjacent bone members 3 can also be displaced so as to twist around the axis extending along the connecting members 4, which also makes it easier to displace each bone member 3 to fit into the receiving portion 2a. The method for attaching each bone member 3 to the receiving portion 2a is not particularly limited; for example, fasteners such as bolts or rivets can be used.

As shown in Figures 3 and 4, multiple roof panels 1 can be arranged side by side and attached to the roof framework 2. Furthermore, the temporary beams 8 can be reused to install multiple roof panels 1. This reduces the number of structural materials required for roof construction, enabling more efficient construction.

The present invention is not limited to the above-described embodiments, and various modifications are possible without departing from the spirit of the invention.

Therefore, the roof panel 1 of the above-described embodiment can be modified as long as it is a unit-type roof panel 1 that can be attached to a roof framework 2, has three or more rib members 3 arranged in a predetermined direction, each of which is placed on and attached to the roof framework 2, and all adjacent rib members 3 are connected to each other so that they can move relative to each other in a direction intersecting the roof panel 1.

For example, the number of bone members 3 is not limited to five, but may be three or more. The number of connecting members 4 can be set appropriately according to the number of bone members 3; for example, if there are three bone members 3, the number of connecting members 4 may be, for example, two. The number of connecting members 4 is not limited to a configuration in which one is provided between adjacent bone members 3, but may be, for example, a configuration in which two or more are provided side by side between adjacent bone members 3. A configuration in which no braces 5 are provided may also be used.

In addition, it is preferable that the roof panel 1 in the above-mentioned embodiment is a roof panel 1 having the above-mentioned configuration and connecting members 4 that connect adjacent frame members 3 by pin joints.

Furthermore, the roof construction method of the above-described embodiment can be modified as long as it is a roof construction method that uses the roof panel 1.

The roof construction method of the above-described embodiment is preferably a roof construction method using a roof panel 1, and includes a transport step in which the roof panel 1 is transported onto the roof framework 2 with one end of all of the frame members 3 of the roof panel 1 connected to one temporary beam 8 and the other end to the other temporary beam 8, and an installation step in which each frame member 3 is removed from the two temporary beams 8 and placed on the roof framework 2 for installation.
