In the ridge-side molded part 34, a rising part 39 is once raised from the ridge-side edge of the face plate part 32 to a predetermined length, and the upper edge is bent outward to form the abutment piece part 36. An abutting piece portion 40 is formed to abut against. Then, the end portion of this abutting piece portion 40 is once folded upward to extend outward, and then folded back and bent inward to form the engaging piece portion 37 including the edge bent portion 38 of the eave side molded portion 33. Forming a holding part 41 with an engaging convex part 41a that can be held,
Then, the upper tip is bent inward again to form the engaging piece portion 42.

The horizontal roof structure according to the configuration of this embodiment is assembled and roofed as shown in FIG. 1 as follows.

Here, for convenience of explanation, each rafter 11 is assumed to be placed over a suitable roof assembly (not shown) at predetermined pitch intervals along the roof slope. Further, the description will be made assuming that the roof board 31 has already been installed on the rafter 11 at the same position via a base 43 having a wedge-shaped cross section.

That is, first, using the hanger 21,
The engaging hook part 25 of the hanger 21 is fitted into the engaging piece part 42 of the ridge side molded part on the eave side which is in the above-mentioned released state, and rotated clockwise around the fitted part. By rotating the engaging tongue piece 26, the engaging tongue piece 26 is inserted and engaged from the insertion part 14 of the engaging hole 13 formed in the rafter 11 into the wedge-shaped engaging part 15 that gradually narrows downward. let

Then, the locking part 23 of the hanger 21 is fitted so as to be in sliding contact with the lower side surface of the locking claw 16 of the rafter 11, and the entire surface of the base plate part 22 is fitted onto the top surface of the rafter 11.
2, and then move this locking pawl 16 to the top surface 1.
The two sides are crimped and fixed by hitting with a hammer or the like as appropriate.

That is, the engaging hook part 25 of the hanger 21 is fitted into the engaging piece part 42 and rotated, and the engaging claw part 25 is rotated.
All you need to do is simply swage the
The roof board 31 and the base 43 can be assembled onto the rafters 11 without using any mounting bolts or nuts.

Subsequently, the widened wedge cross-section end edge 43a of the ridge side base 43 is mounted and supported on the base plate 22 of the hanger 21, and then the eave side molded portion 33 of the ridge side roof board 31 is engaged. The piece part 37 is inserted into the holding part 41 of the ridge side molded part 34, and the edge bent part 3 at the end of the engaging piece part 37 is inserted.
8 is the engagement convex portion 41a of the ridge side molded portion 34 held from the outside by the bent concave portion 24a of the hanger 21.
The ridge side base 43 is covered with the face plate portion 32, and the base plate 43 is inserted.

Thereafter, by repeating the above operations, the horizontal roof panels can be raised from the eaves side to the ridge side, thereby obtaining a horizontal roof structure.

Additionally, the ridge side molded portion 34 with the configuration of this embodiment
In the connection engagement between the eave side molded part 33 and the eaves side molded part 33, one role is that the presence of the rising part 39 on the face plate part 32 causes the contact pressure part of each abutment piece part 36, 40 to
The position rises from the corner of the inner corner in contact with the face plate part 32, and therefore wind and rain blown up along the face plate part 32 are not blown directly onto this contact pressure part. It can sufficiently alleviate the influence of pressure, eliminate as much as possible the intrusion of rainwater from the same contact pressure part, and also effectively prevent the infiltration of sand, mud, and other dust caused by wind and rain. .

Furthermore, even if some rainwater were to infiltrate from this contact area due to capillary action, it would be a seepage with almost no pressure, so it would be flat and infiltrate at this contact area. Coupled with the strong engagement and butt holding, even if the air that has previously existed in the holding part 41 is eliminated, there is a very low possibility that it will reach the inside, and a more effective waterproofing effect can be obtained here. It is possible.

In the structure of this embodiment, the base 43 having a wedge-shaped cross section is used, so even if the thickness of the roof above the rafters 11 is relatively thin, the base 43 can be applied to almost the entire face plate portion 32 of the horizontal roof board 31. The roof panels 31 and the hangers 21 can be placed in close contact with each other, and the roof panels 31 and the hangers 21 can be made smaller, making them less expensive.

〔Effect of the invention〕

In the combination structure of horizontal roof rafters and hangers according to the first aspect of the present invention, the engagement tongues hanging from the base plate of the hangers are inserted into the engagement holes drilled in the lower part of the rafters. In addition, the board can be fixed by caulking without using fixing tools such as bolts or nuts using the locking claws cut and raised on the upper side. The ridge side molded part of the installed eave side horizontal roof board, and by extension the entire roof structure, can be fastened and fixed well and effectively while maintaining sufficient strength by an extremely simple operation.

Furthermore, it can be mounted and supported on the eave side edge of the base on the base plate of the hanger.

In the horizontal roof structure according to the second aspect of the present invention, in addition to the effect produced by applying the combination structure of rafters and hangers according to the first invention, the horizontal roof structure according to the second aspect of the present invention has the effect that After placing the base material on top of the tiered part, attaching the eave side molding to the ridge side molding of the horizontal roof shingles, the roof structure can be built with sufficient strength and excellent watertightness through an extremely simple operation.
