Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eaves structure for an entrance porch used for general houses and the like.

[0002]

2. Description of the Related Art As shown in FIGS. 2 (a) and 2 (b), an entrance porch 10 used in a general house or the like comprises an eaves structure 10a and a pair of left and right columns 10b and 10b. In the figure, 10c is the top of the porch tile, 10d is the outer wall surface of the building, and 9 is the frame member of the eaves structure 10a.

Conventionally, as the eaves structure 10a of the entrance porch 10 as described above, for example, the Japanese Utility Model Publication No. 3-20401 or the like and that shown in FIG. 3 have been used. In the eaves structure shown in FIG. 3, the frame members 1, which are provided above the entrance porch,
2 (member corresponding to reference numeral 9 in FIG. 2) is provided with two divided roofing materials 3 and 4 made of vinyl chloride steel plate. The roof materials 3 and 4 are arranged so as to be inclined, and the roof material 3 is arranged below the roof material 4 and connected by rivets or the like. Further, since the roofing materials 3 and 4 are made of vinyl chloride steel plates, plywoods 5 and 6 are attached as backing materials on the lower surface side thereof in order to ensure strength.

In order to fix and hold these roofing materials 3 and 4 in an inclined state, below the roofing materials 3 and 4 (plywood 5 and 6), the width direction of the roofing materials 3 and 4 ( A plurality of frames 7 and 8 are provided at appropriate intervals in a direction orthogonal to the inclination direction. The frames 7 and 8 are preliminarily subjected to oblique bending so that they can be inclined at a predetermined angle only by placing the roofing materials 3 and 4 and the plywoods 5 and 6.

[0005]

However, in the above-mentioned eaves structure of the entrance porch, the plywoods 5 and 6 are required as the backing material in order to secure the strength of the roofing materials 3 and 4, and the roofing material 3 is used. Since multiple frames 7 and 8 that have been subjected to diagonal bending are required to place and fix them in a slanted position, this will result in high cost, and it is extremely difficult to perform diagonal bending of the frames 7 and 8. Is. Further, since it is a two-part structure composed of two roof members 3 and 4, there is a problem that the number of parts increases.

The present invention is intended to solve such a problem, and the roofing material alone can ensure sufficient rigidity to simplify the structure of parts, improve productivity and reduce cost. The purpose is to provide an eaves structure for the pouch.

[0007]

In order to achieve the above object, the eaves structure of the entrance porch according to the present invention comprises a roof material which forms an eaves structure arranged above the entrance porch, and a pentite material.
By taking one, it is formed as one piece,
A reinforcing angle material is attached by welding to the lower surface side of the inclined roof surface of the roof material.

In addition, folding portions are formed on both sides of the roof material in the lower and upper sides in the inclination direction, and the folding portions are
The roofing material may be fixed above the entrance porch by attaching it to the edge of a parapet disposed above the entrance porch.

[0009]

In the eaves structure of the entrance porch of the present invention described above (Claim 1), the roofing material alone has sufficient rigidity, so that a conventional split structure or a reinforcing material such as plywood is used. There is no need to provide it. Also, by fixing the roof material using the parapet above the entrance porch
(Claim 2), the conventional frame or the like that has been subjected to oblique bending is not required.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The eaves structure of an entrance porch as an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a side view thereof. The eaves structure of this embodiment is also shown in FIGS.
It is applied to the eaves structure 10a of the entrance porch 10 as shown in FIG.

In FIG. 1, reference numeral 11 denotes a roof material having an eave structure which is arranged above the entrance porch.
Is a piece of pentite material (for example, width 1219 mm × length 243
6 mm) so that it is formed as an integral body. The surface of the roof material 11 is coated, and a plurality of L-shaped angle materials 12 (5 in FIG. 1) for reinforcement are provided on the lower surface side of the inclined roof surface 11a in the width direction ( It is attached by welding along the (direction orthogonal to the tilt direction).

Further, folding portions 11b and 11c are formed on both sides of the roof material 11 on the lower side in the inclination direction and on the upper side in the inclination direction. Here, the folding | returning part 11b of the inclination direction lower side is formed longer (higher) than the folding | returning part 11c of the inclination direction upper side, and these folding | returning parts 11b and 11c are the edges of the parapets 13 and 14 above a front porch. Rivets 15,
By mounting at 16, the roof material 11 is fixed above the entrance porch while inclining the inclined roof surface 11a at a predetermined angle. Reference numeral 17 in FIG. 1 is a frame provided above the entrance porch.

With the above-described structure, the roofing material 11 has a sufficient rigidity by itself, so that the reinforcing material such as a plywood (refer to reference numerals 5 and 6 in FIG. 2) having a two-divided structure as in the prior art is used. There is no need to provide it. Further, since the roofing material 11 is fixed by using the parapets 13 and 14 above the entrance porch, the frame which is diagonally bent as in the conventional case
(See reference numerals 7 and 8 in FIG. 2) and the like are also unnecessary.

As described above, according to the eaves structure of the entrance porch of this embodiment, the material of the roof material 11 is changed from the vinyl chloride steel plate to the pentite material, and the L-shaped angle material 12 is welded, so that the single material is sufficient. The rigidity can be secured, the backing material (plywood) and the frame parts for tilting, which were required in the past, can be reduced, and the two parts are integrated into one piece, which greatly simplifies the parts configuration and improves productivity. And the manufacturing cost will be greatly reduced.

The present invention is not limited to the above-mentioned embodiments, and is included in the scope of the present invention even if the design is changed without departing from the gist of the present invention. For example, although the roof material 11 is attached to the edge portions of the parapets 13 and 14 in the above-described embodiment, other portions, for example, the eaves frame member (reference numeral 1 in FIG. 2 disposed above the entrance porch). 2)).

[0016]

As described above in detail, according to the eaves structure of the entrance porch of the present invention (Claim 1), the roof material is formed as an integral body by taking one piece of pentite material, and its inclination With a very simple structure in which a reinforcing angle member is attached to the lower surface side of the roof surface, sufficient rigidity can be secured with the roof material alone, so the component structure can be extremely simplified, productivity is improved, and manufacturing costs are reduced. There is an effect that can be done.

By forming folding portions on both sides of the roofing material in the lower direction of the roof and in the upper side of the roof direction, and attaching the respective folded sections to the parapet edge above the entrance porch.
(Claim 2) In addition, a conventional frame or the like that has been subjected to oblique bending is not required, and the component structure can be further simplified, which contributes to improved productivity and reduced manufacturing cost.
