Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an eaves structure for improving eaves strength.

<Prior Art> When the eaves of a building are put out, a feeling of weight and a sense of stability is generated in the roof, and a feeling of solidity can be generated in the whole. In addition, eaves constructed for such a purpose are often provided with eave ceilings that block the back of the eaves.

In a conventional eaves structure with an eaves ceiling, a nasal cover is provided at the tip of the rafter protruding from the nose purlin on an extension of the roof slope. Below the rafter projected from the nose purlin, a field edge is attached in the horizontal direction across the back side of the nose cover and the eaves girder. Therefore, both side surfaces of the rafter and the field edge have the same vertical plane shape. The eave ceiling is nailed to the lower surface of the field edge, and the eave ceiling covers the lower surface of the eave from the cover of the nose to the eaves girder.

<Problems to be solved by the invention> The eaves of a building are large when it is desired to give a solid feeling to the whole building. However, the larger the eaves, the more resistance to the wind blow. For this reason, the conventional eave structure consisting of rafters and wild rims is not sufficient in terms of strength, and there is a restriction on how large the eaves should be. Also, in order to increase the strength of the eaves, a truss-like eave base assembly using light iron is also used, but the construction cost is higher than that of wooden construction, and the installation and adjustment work requires time and labor, which is rational. Could not be done.

The present invention has been made in view of the above circumstances, and provides an eaves structure capable of improving the strength of the eaves.
The purpose is to secure enough eaves.

<Means for Solving the Problems> The present invention, which was made to achieve the above-mentioned object, has a rafter tip side laid over a nose purlin and a tip side of a field edge fixed to an eaves girder, respectively. While projecting outward from the outer wall, the projected rafter and field edge are connected by a pair of vertical members to form an eaves base, and the side surfaces of these rafters, field edges and vertical members are in the same vertical plane. In the eave structure that is arranged,
The eaves reinforcing plate is cut along the outer edge shape of the rafter, the edge, and the vertical member, and the eaves reinforcing plate is fixed to both sides of the rafter, the edge, and the vertical member protruding from the outer wall.

<Operation> In the eaves structure of the present invention, the rafters protruding from the outer wall of the building, the eaves reinforcing plates are fixed to both sides of the field edge and the vertical member, respectively. The field edge and the vertical members are integrated into a panel by the eaves reinforcing plate. As a result, the eaves base strength of the eaves base made of rafters, wild edges, and vertical members is given a proof stress in the plate surface direction of the eaves side reinforcing plate, so that the eaves strength is increased accordingly.

<Embodiment> Hereinafter, a preferred embodiment of the eaves structure according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a side view of an eaves tip portion showing a state in which an eaves tip reinforcing plate according to an embodiment of the present invention is attached, and FIG. 2 is a plan view thereof.

One end side of the rafter 1 hung over the nose purlin (not shown)
It is in a state of being projected outward from the outer wall 2 of the building. Below the rafter 1, a field edge 3 whose one end is fixed to an eaves girder (not shown) is horizontally arranged. Vertically extending bundle vertical members 4 are fixed to the tips of the rafters 1 and the edges 3 of the field, and the tips of the rafters 1 and the edges 3 are connected and fixed via a bundle 4. An inner gutter 5 is provided on the tip side of the bundle 4 in a direction orthogonal to the rafter 1. To the rafter 1 on the side of the nose purlin and the edge 3 on the side of the eaves girder, a splint vertical member 6 extending in the vertical direction is fixed between both. Therefore, the rafter 1 and the field edge 3 protruding outward from the outer wall 2 are connected and fixed at the tip end side and the base end side by the bundle 4 and the splint 6, respectively, to form an eave base. The sides of the rafter 1, the field edge 3, the bundle 4, and the splint 6 have the same vertical plane.

On the side surface of the rafter 1, the field edge 3, the bundle 4, and the splint 6, an upper side 7 which is one side is cut out along the upper edge of the rafter 1,
The eaves tip reinforcing plate 9 whose lower side 8 which is the other side is cut out along the lower edge of the field edge 3 is nailed and fixed. Since the eaves reinforcing plate 9 is formed of plywood, without increasing the plate thickness,
Proof strength is secured. Further, the vertical sides 10a and 10b connecting the upper side 7 and the lower side 8 are also cut out along the outer edges of the bundle 4 and the splint 6. That is, the eaves tip reinforcing plate 9 has a trapezoidal shape in which four sides are cut along the edges of the rafter 1, the field edge 3, the bundle 4, and the splint 6. As shown in FIG. 2, the eaves reinforcing plates 9 are fixed to both sides of the rafter 1, the field edge 3, respectively, and the rafter 1, the field edge 3, the bundle 4, the splint 6
Are connected by being sandwiched by the eaves reinforcing plate 9.

In the eaves structure with the above configuration, rafter 1, field edge 3, bundle
4, By fixing the upper side 7, the lower side 8 and the vertical sides 10a, 10b on both sides of the splint 6, the rafter 1, the field edge 3, the bundle 4,
The eave base made of splints 6 is integrated into a panel shape by a pair of eave tip reinforcing plates 9. As a result, the strength of the eaves reinforcing plate 9 in the plate surface direction is given to the strength of the eave base (rafter 1, field edge 3, bundle 4, splint 6) that is integrated in a panel shape. .

As described above, in the eaves structure of the present embodiment, since the proof strength of the eaves reinforcing plate 9 in the plate surface direction is given to the strength of the eaves base, the rafters 1,
The field edge 3, the bundle 4, and the splint 6 are connected by a high joining force to form an integral structure, which can improve the strength of the eaves. For this reason, as compared with the eaves portion using light iron, the eaves strength can be maximized at a low cost and with a simple attachment construction.

The eaves structure according to the present invention capable of improving the strength of the eaves is suitable for use when a large eaves is desired to be provided. It can also be used to improve the strength of the eaves.

<Effect of the device> In the eaves structure according to the present invention, the rafters, the field edges and the vertical members protruding from the outer wall of the building are integrated into a panel shape by the eaves reinforcing plate, so that the connection strength in the lateral direction of the rafters and the field edges. The proof strength of the eaves reinforcing plate in the plate surface direction is imparted to the eaves and the eaves strength can be significantly improved. As a result, it is possible to maximize the strength of the eaves at a low cost by simple and easy mounting work, and to sufficiently secure the eaves of the eaves even in wooden construction.
