The roof structure in this embodiment is applied to a two-story general residential building made of prefabricated wooden and steel frames.

As shown in FIG. 2, the roof surface is constructed of a plurality of (eight in the illustrated example) roof panel members 1 each having a generally rectangular planar shape.

Roof panel material 1 before roof surface construction, that is, each roof panel material 1 during storage or transportation before construction, etc.
As shown in FIG. 3, there is a pair of C-shaped steels 2 that extend in the direction perpendicular to the plane of the drawing and are facing each other, and a predetermined interval between the pair of C-shaped steels 2 in the direction perpendicular to the plane of the drawing. A plurality of crosspieces 3 are erected and arranged in a row at a distance, and a panel-shaped field board 4 such as an asbestos cement board is laid on the crosspieces 3.
It is formed from roofing material 5 laid on the surface side of this shedding board 4.

[0020] On both ends of the roof panel material 1 in the transverse direction,
Fitting portions 5A and 5B, which are formed by bending the roofing material 5 and sealing members 6 provided at the bending portions, extend along the longitudinal direction.

Further, a plurality of bolt insertion holes 2A are arranged in a row on the side surface of the C-shaped steel 2, so that the roof panel members 1 adjacent to each other in the front-rear direction of the roof (in the direction perpendicular to the plane of the drawing in FIG. 1) are connected to each other. As shown in FIG. 4, this is done by the bolt/nut 7 passing through the bolt insertion hole 2A, and by the fitting of the fitting parts 5A and 5B and the engagement of the folded ends of each of the fitting parts, rain is removed from the joint part. Leakage is prevented.

As shown in FIG. 1, a plurality of rows of coupling fittings 8 having pin insertion holes are provided on the back side of each roof panel material 1 forming the lower end side of the roof surface.

On the other hand, the H-shaped steel 9 (
A coupling fitting 10 having a male threaded pin is disposed on the roof support structure, and a coupling fitting 8 on the roof panel material 1 side is disposed on the roof support structure.
By inserting the pin of the coupling fitting 10 on the H-shaped steel 9 side into the pin insertion hole and loosely fastening it with a nut (not shown), as shown in FIG.
is tilted using the pin of the coupling fitting 10 as a fulcrum, and the pair of tilted roof panel members 1 are connected to the H on both sides of the roof facing each other.
By mutually supporting the free end sides of the shaped steel 9 approximately in the center, a roof without an attic roof frame is constructed.

[0024] Therefore, in the attic of the roof structure of this embodiment, a roof frame structure consisting of roof bundles, flint beams, etc., as in the past, is not constructed.

Next, as shown in FIG. 2, a shade 11 having a mountain-shaped cross section is attached to the top of the roof surface formed by the roof panel material 1 constructed in this way to prevent rain from flowing from the top. Leakage is prevented.

Next, the operation of this embodiment will be explained.

For example, the roof structure of this embodiment is constructed as follows.

First, the framework of the building is constructed.

[0029] In this case, in this embodiment, since the conventional attic roof frame structure consisting of shed bundles, flint beams, etc. is not required, such a roof frame is not constructed, but the roof is The H-shaped steel 9 on the supported eave girder 9A has
A coupling fitting 10 is provided.

Next, at the construction site, the pair of roof panel materials 1 that have been processed in advance at a factory or the like are supported by a pair of opposing H-shaped steels 9 at both ends of the roof using a hoist or the like, and the joining fittings of the roof panel materials 1 are attached. After inserting the pin of the coupling fitting 10 on the H-shaped steel 9 into the pin insertion hole 8 and loosely fastening it with a nut (not shown), as shown in FIG. The pin of the coupling fitting 10 is tilted as a fulcrum, and the pair of tilted roof panel members 1 are mutually supported by their free ends at approximately the center of the H-beams 9 on both sides of the roof facing each other.

Next, the next pair of roof panel materials 1 are placed adjacent to each other in the front-rear direction of the pair of roof panel materials 1 thus constructed, and constructed in the same manner as described above.

Thereafter, in the same manner as above, a pair of roof panel members 1 are successively constructed adjacent to each other to construct a roof as shown in FIG. 2.

Then, the bolts and nuts 7 are tightened to firmly connect the roof panel members 1 that are adjacent to each other in the front-rear direction of the roof (perpendicular to the plane of the paper in FIG. 1), and also in the left-right direction of the roof (in FIG. After the roof panel members 1 adjacent to each other in the left-right direction are firmly connected using a predetermined connector (not shown) or the like, a shade 11 having a mountain-shaped cross section is attached to the top of the roof surface.

According to the roof construction method and roof structure of this embodiment constructed in this way, a pair of roof panel members 1 each having a substantially rectangular planar shape are constructed using the pins of a pair of coupling fittings 10 on both sides of the roof as fulcrums. By tilting the pair of roof panel members 1 and supporting each other with their free ends at approximately the center of both sides of the roof, a roof without an attic roof frame can be constructed, so there is no need for a conventional attic roof frame. As a result, the construction of the roof can be simplified or simplified, and the construction time can be shortened. Also, since the attic space is not obstructed by the roof frame, the attic space can be used more effectively. You can plan to use it.

Furthermore, in this embodiment, a plurality of pairs of roof panel materials 1 are used, and since a roof is constructed by the plurality of pairs of roof panel materials 1, it is possible to downsize each roof panel material 1. Therefore, storage and transportation of the roof panel material 1 and construction of the roof can be facilitated.

[0036] Above, the invention made by the present inventor has been specifically explained based on examples, but the present invention is not limited to the above-mentioned examples, and can be modified in various ways without departing from the gist thereof. Needless to say.

For example, the roof construction method and roof structure of the present invention can be applied to arbitrary buildings such as wooden structures, steel frames, concrete structures, concrete structures, and various prefabricated structures.
