BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view showing an embodiment of a structure for joining inclined members such as a roof according to the present invention. 1 is an overall perspective view of the present embodiment, FIG. 2 is a plan view of FIG.
FIG. 2 is a side view of FIG. 1. In each of these drawings, the present embodiment is a joint structure of a lower end portion 2 of an inclined member 1 and a corner portion 4 of a support base material 3 at a corner portion such as a roof of a building. A thin substrate 6 is placed on the substrate 6, and two upright plates 7, 7 are erected on the substrate 6. Here, the roof of the building broadly includes a structure having a slope such as a roof, an eave, or a stair.

The above-mentioned inclined member 1 is a supporting member for supporting an upper member such as a roofing material provided on a roof or the like at an arbitrary gradient (for example, any gradient from 4 to 12.5). For example, in a roof, it is an inclined member such as a corner block or a corner block, and is joined to the supporting base material 3 at the lower end 2 thereof. On the other hand, the support substrate 3
Includes various support members such as vertical members such as column members and wall members and horizontal members such as cross members and panel members, which are joined to the inclined member 1 at corners 4 thereof. It is.

As shown in FIG. 3, the substrate 6 mounted on the corner portion 4 of the support base material 3 has an arbitrary planar shape that does not protrude from the outer surface of the corner portion 4 and is rolled. It is formed by punching a thin iron material. As shown in FIG. 4, the corners 4 of the support substrate 3
a is substantially L-shaped, and the substrate 6 is formed in a substantially triangular shape to be placed at least on the peripheral portion 4a. That is, in the present embodiment, the supporting base material 3 is formed by abutting two cross members, and since the corner portion 4 is formed as a joint portion of the two cross members, the corner portion 4 is formed. The peripheral portion 4a on the upper surface of the fourth member 4 has a substantially L-shape composed of the upper surfaces of two cross members.

Here, the substrate 6 is mounted at least on the peripheral portion 4a of the corner portion 4 and is also bridged between both ends of the substantially L-shaped peripheral portion 4a.
As a whole, the plane shape is formed as a substantially triangular shape. The shape of the substrate 6 is not limited to the shape of this embodiment, and can be stably mounted on the corner portion 4 of the support base material 3 and can be provided with the upright plate 7 on the upper surface thereof. Should be fine.

The substrate 6 has an outer portion 11 bent downward to form a bent piece 12, and the bent piece 12 is fixed to the side surface of the corner portion 4 of the support substrate 3.
That is, as shown in FIGS. 1 and 2, the substrate 6 is formed by bending a piece of the outer portion 11 along the peripheral portion 4 a of the corner portion 4 of the support base material 3 downward at a substantially right angle to form a bent piece 12. The inner surface of the bent piece 12 is brought into contact with the side surface of the corner 4, and a fastening nail 19 is driven through a plurality of nail holes 11 formed in the bent piece 12, and the support base material 3 is formed. It is fixed to.

As described above, the substrate 6 has its outer portion 11
Is bent downward to form a bent piece 12, and the bent piece 12 is fixed to the side surface of the corner 4 of the support base material 3, so that the bent piece 12 is attached to the corner 4. By placing the substrate 6 on the supporting base material 3 while being in contact with the substrate 6, the substrate 6 can be disposed at a predetermined position, and the position of the substrate 6 can be determined very easily. In addition to providing the bent piece 12, by fixing the bent piece 12 to the corner portion 4 of the support base 3, the movement of the substrate 6 in and out of the substrate 6 can be regulated by the bent piece 12. Can be more firmly linked to the support substrate 1. In the present embodiment, as shown in each figure, the bent portion 12 is provided by bending the outer portion 11, which is the outer portion of the substrate 6, but the inner portion is bent instead of the outer portion. The bent piece 12 may be formed in this manner, and the same effects as described above can be obtained by forming another bent member by welding instead of bending. Alternatively, even in the case of bending, instead of being bent in advance, only the slit is formed in the outer portion 11 of the substrate 6 to make it easy to bend at the construction site, and when transported to the construction site, it is flat. The handling may be improved as a matter of course.

The upright plate 7 is linked to the upright plate 7 at substantially the center thereof, and both of the reinforcing plates 8A and 8B have substantially the same height as the upright plate 7 at the linking portion with each of the upright plates 7. It is formed as a substantially triangular plate having an inclined surface inclined downward and outward.

As described above, a plurality of reinforcing plates 8,
8, and the reinforcing plates 8 are linked to the upright plates 7, 7 at right angles, so that the upright plates 7, which are to be deformed by transmitting the load of the inclined member 1, are deformed in the deformation direction. Can be supported by the reinforcing plate 8 disposed at the same position, and each of the upright plates 7 can be strongly reinforced. In this embodiment, the reinforcing plate 8 is connected to the substrate 6, the upright plate 7,
