Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skylight drainer which is fixed around a wooden frame of a skylight and prevents rainwater from leaking from around the skylight.

[0002]

2. Description of the Related Art FIG. 3 (A) is an exploded perspective view showing the structure of a conventional drainer for skylights. The drainer for skylights includes an eaves side draining member 3, a side cutting member 4, and a ridge side draining member 5. And consists of
These drainers 3, 4 and 5 are sequentially fixed to the eave-side surface, side surface, and ridge-side surface of the wooden frame 1 from the eaves side by a fixture 2 such as a nail. The eaves side draining member 3 and the ridge side draining member 5 are respectively composed of a central member 3a, 5a and side members 3b, 5b on both sides thereof, and a connecting portion 6 thereof is shown in FIG.
As shown in FIG. 3B which is an F-F enlarged cross-sectional view of FIG. 3A, the upstream edge of the rainwater (the edge 5c of the central member 5a in the illustrated example) is the downstream edge (the illustrated example). Then, the side member 5b
The side edges 5d) are joined by folding in such a manner as to cover them. In this case, in order to prevent water from leaking from the joint portion 6, the sealing material 7 is attached to one joint edge 5c and then bent and joined.

[0003]

According to such a conventional structure, it is necessary to join the eaves side draining member 3 and the ridge side draining member 5 by bending the connecting edges 5c and 5d, and to attach the sealing material 7. Therefore, the man-hours for manufacturing and the number of members increase, which causes a high price of the draining material.
In order to solve this problem, it is conceivable to form the joint portion 6 by welding. However, since these drainers are generally made of thin steel plates, the conventional method of butt welding the edges of flat plates and welding the welded portion In the field of draining skylights, welding is not used to join the central members 3a, 5a to the side members 3b, 5b because of the perforations.

Further, in the above conventional structure, since the ridge-side draining member 5 forms the same surface on both the central member 5a and the side members 5b on both sides thereof, the flow of water accumulated in the ridge-side draining member 5 to the side portion. There was a problem that was worse.

In view of the above-mentioned problems, the present invention makes it possible to easily manufacture a draining member, which makes it possible to reduce the price, and to prevent rainwater from flowing from the central member to the side member of the ridge side draining member. It is an object of the present invention to provide a skylight drainer having a well-structured structure.

[0006]

In order to achieve this object, in the skylight drainer according to the present invention, the ridge-side draining material and the eaves-side draining material of the skylight wooden frame are installed on the ridge side and the eaves side of the wooden frame. Each of the central members is fixed to a surface, and side members provided on both sides of each central member, the side members having a rising portion on the side of the central member, and a side edge of the central member or the side portion. It is characterized by having a structure in which one of the upper edges of the rising portions of the members is projected with respect to the other and is abutted and welded.

[0007]

As described above, the water drainer for a skylight of the present invention has one of the edges forming the welded portion projected and welded,
The heat capacity of the weld becomes large, and no hole is formed in the weld, so that a good weld can be obtained. Further, since the flat surface portion of the central member is higher than the flat surface portion of the side member, rainwater flows from the flat surface portion of the central member to the flat surface portion of the side member, and the flow of rainwater becomes good.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an exploded perspective view showing an embodiment of a water drainer for a skylight according to the present invention. The drainer according to the present invention includes central members 3a and 5a for fixing the eaves-side draining member 3 and the ridge-side draining member 5 to the eave-side and ridge-side surfaces of the wooden frame 1, and the central members 3a and 5a, respectively. Side members 3b, 5b provided on both sides
And the side draining member 4 (not shown in FIG. 1) is the same as the conventional example, but the rising portions 3e on the side of the central members 3a, 5a of the side members 3b, 5b. 5e, and the side edges of the central members 3a, 5a are welded (8) to the upper edges of the vertical portions 3e, 5e (see FIG. 2 which is an enlarged cross-sectional view taken along line EE of FIG. 1).
(See (A)).

As shown by the ridge-side draining member 5 in FIG. 2 (B), the welded portion 8 is formed on a plate surface near the side edge of the central member 5a made of, for example, a steel plate. Member 5
The upper edge 5g of the rising part 5e of b is butted, the side edge 5f of the central member 5a is made to project from the plate surface of the rising part 5e by the width of x, and the butted part including the projecting part is welded to join. It was done. In this case, the mold 9 and the clamp mold 10 each having the stepped portion 9a matching the shape of the butted portion
By fixing these members 5a, 5b to the mold 9 by closely adhering them to each other, the heat transfer of the welding heat to the mold 9 is improved, and the welding torch 11 is guided along the abutting portion. Welding is carried out by moving it. In this case, plasma welding is most suitable for performing welding at a low cost and on a draining material having a small thickness. The thickness of the draining material to which the present invention is applied is 0.1 mm to 3 mm, but if the above-described welding structure is adopted, 0.1 mm to 0.9 mm which could not be conventionally welded.
Welding is also possible for draining. The protrusion width x of the abutting portion may be about 0.5 mm to 1 mm.

As described above, by adopting a structure in which the upper edge 5g of the rising portion 5e of the side member 5b is welded to the side edge 5f of the central member 5a, the flat surface portion 5h of the central member 5a becomes the side member 5b. It becomes higher than the flat portion 5i, and as a result, as shown in FIG.
As indicated by the arrow a, the rainwater that collects on the side of the central member 5a smoothly flows to the side of the side member 5b, and drainage is performed well.

In the above embodiment, the side edge 5f of the central member 5a is projected from the abutting portion with the rising portion 5e, but as shown in FIG.
The side edge 5f is abutted against the plate surface of e and the rising portion 5e is formed.
The upper edge 5g may be projected upward and welded. In addition, the wooden frame 1, central members 3a, 5a, side members 3b, 5b
Various changes and additions can be made to specific shapes, structures, and combinations of the above.

[0012]

According to the present invention, the side member is provided with a rising portion, and the upper edge of the rising portion and the side edge of the central member are butted against each other so that they are welded to each other. By doing so, it becomes possible to join the thin side member and the central member by welding, which was not possible in the past, and the draining material can be manufactured more easily compared to the conventional bending connection, and a significant cost reduction is possible. It will be possible. Further, the flow of rainwater from the central member to the side member of the ridge-side draining member is good, and draining is well performed.
