Description

[Detailed description of the invention] [Field of industrial application] The present invention is a drainer for an overhang that can simply and easily drain the front edge of the lower end of a building's overhang by using a sheet metal crown plate and a lower drainer plate. Regarding structure.

[Conventional technology]

For example, as illustrated in FIG. 1, in order to make effective use of the upper floors of a building, an overhang c is often provided in the upper floor part a that overhangs the lower floor part b.

Conventionally, draining of the outer part of the lower end of the overhang c was carried out by connecting the crown plate f to the base plate e, as illustrated in FIG.
In addition, the lower draining plate g is attached to the crown plate f.
It was nailed to the bottom surface via a mounting plate h that was fixed using nails.

[Problem that the invention attempts to solve]

As long as the mounting plate h is used in this way, the number of man-hours required for mounting it increases, the cost increases, and the nailing work is troublesome, requiring time and effort.

An object of the present invention is to provide a draining structure (hereinafter referred to as structure) for an overhang portion that can solve the above-mentioned problem by making it possible to easily attach a lower draining plate to the crown plate without using the mounting plate.

[Means for solving problems]

The present invention is a drainage structure for an overhang that drains the lower end and outer edge of an overhang where the upper floor part of a building projects outward, and has an outer piece and an inner piece that hang down outside the base piece and at the inner edge. In addition, the base piece of the sheet metal crown plate, which has a horizontal inward cut and raised piece on the outer piece and an inwardly bent piece on the lower end of the inner piece, is used to form the overhang of the building. A locking piece facing outward provided on the outer standing piece of the lower horizontal plate, which is fixed to the lower surface of the base material on the outer surface of the cantilever beam, and has an outer standing piece and an inner standing piece that stand up on the outside and inside edge of the bottom piece. is locked to the cut-and-raised piece, and the outwardly directed protruding piece provided at the upper end of the inner upright piece is placed on the bent piece of the inner piece, thereby attaching the lower drain plate to the crown plate. This is a drain structure on the overhang that is characterized by the fact that it can be attached.

[Effect]

For the lower drain plate, the outward locking piece provided on the outer vertical piece is connected to the inward cut and raised piece of the crown plate, and the outward protruding piece of the internal vertical piece is connected to the inward bent piece of the crown plate. It can be mounted by placing the parts on the respective parts, making the mounting work more efficient, and by omitting the conventional mounting plate, it is possible to improve workability and reduce costs.

〔Example〕

One embodiment will be described below based on the drawings.

In FIGS. 2 and 3, the structure of the present invention is such that the upper floor part a of the building drains the lower end of the overhanging part c that projects outward using a crown plate 2 and a lower draining plate 3, The lower end of the projecting portion c is supported by a cantilever beam 5 made of lattice material. Cantilever beam 5
A panel support beam 9 that supports the wall panel 6 on the floor via a support metal fitting 7 is screwed to the upper part of the outer surface of the panel support beam 9, and below the panel support beam 9, base materials 10 and 11 having the same width as the panel support beam 9 are attached above and below. mounted on. The lower surface of the lower base material 11 is aligned with the lower surface of the cantilever beam 5, and the base materials 10 and 11 are nailed and fixed to the cantilever beam 5.

The crown plate 2 has an outer piece 14 on the inner edge outside the base piece 13.
and the inner piece 15 are made to hang down, and the outer piece 14 has an inner part,
That is, a horizontal cut-and-raised piece 16 facing the building side is formed, and a horizontal bent piece 17 that is bent inward is formed at the lower end of the inner piece 15, so that the crown plate 2
is made of a sheet metal material obtained by bending a metal plate such as a decorative steel plate, and the base piece 13 of the crown plate 2 is fixed using a bolt passing through the base material 11.

The lower draining plate 3 has an outer standing piece 22 and an inner standing piece 23 upright on the outside and inner edge of the bottom piece 21, and the outer standing piece 22 has a locking piece 24 horizontally protruding outward. The inner vertical piece 23 also has an outwardly extending horizontal protruding piece 25 formed at its upper end, and is similarly made of a sheet metal member. The lower draining plate 3 has its locking piece 24 placed on the cut and raised piece 16 and the projecting piece 2
5 is placed on the bent piece 17 and attached to the crown plate 2.

The outside of the panel support beam 9 and the base materials 10 and 11 is decorated with a curtain plate 30. The curtain plate 30 has a raised piece 3 that is covered with rain and comes into contact with the wall panel 6.
A covering part 33 that hangs downward is provided at the outer edge of the cover 33 through a horizontal piece 32 at the lower end of the 1, and a V-shaped part 35 having an inwardly sloping part is provided at the lower end, and at the inner edge thereof, A lining piece 36 that abuts the lower end of the outer piece 14 and a standing piece 37 that rises at the tip thereof are provided.
Further, by bringing the vertical piece 37 into contact with the inner surface of the outer piece 14, the lower end of the curtain plate 30 is locked. In addition, the gap between the outer piece 14 and the outer standing piece 22 is filled with caulking material 40 to prevent rain.
The upper end of the projecting piece 25 locks the outer end of the eaves ceiling board 50.

However, in the structure of the present invention, the lower drain plate 3
The locking piece 24 and the protruding piece 2 are moved outward.
5 on the cut-and-raised piece 16 and the bent piece 17, it can be attached without the need for nailing, mounting plates, etc., and the installation work can be extremely simplified and work efficiency can be improved.

Note that the locking piece 24 is, as illustrated in FIG.
A U-shaped groove 2 that opens outward at the lower part of the locking piece 24 by curving the outer standing piece 22 into a flat horizontal S-shape
7, and the cut and raised pieces 16 can be fitted into the U-shaped grooves 27 with spring properties, thereby stabilizing the connection of the cut and raised pieces 16.

[Effect of idea]

As mentioned above, the structure of the present invention allows the lower drain plate to be attached to the crown plate without the need for the mounting plate used in conventional structures, and also greatly improves the installation process without the hassle of nailing. It can have excellent effects such as moisturizing.

Note that the structure of the present invention can be modified such that the locking piece and the cut-and-raised piece and the projecting piece and the bent piece can be respectively joined using an adhesive.
