DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage structure for a fitting provided on a deck-like structure such as a balcony.

[0002]

2. Description of the Related Art In a balcony or the like, a lower frame is provided with a sufficient gradient so that drainage of a window (fitting) serving as an entrance / exit flows on a deck material of the balcony, and the deck material is sufficiently attached to a lower frame of the window. Located at a lower position. In order to prevent the drainage of the window from flowing between the balcony and the outer wall, the drainage smoothly flows from the lower frame onto the deck material by using a water return.

[0003]

In such a conventional drainage structure for fittings, a large step is formed between the lower frame of the window and the deck material. There was a problem that it was difficult or impossible to get in and out of the balcony. However, if the lower frame and the deck material are arranged at the same level, such a problem is solved. However, if the lower frame and the deck material are simply set to the same level, drainage of the lower frame does not flow smoothly to the deck material side, and a problem arises that rainwater or the like easily enters the room.

[0004] It is an object of the present invention to provide a drainage structure for a fitting in which the lower frame and the deck material can be arranged at substantially the same level without impairing the smoothness of drainage in the lower frame of the fitting. I have.

The upper edge portion on the lower frame side is disposed at least at a position lower than the upper surface of the base portion.

According to this structure, the drainage of the fitting received by the base portion of the lower frame is guided from the front end of the base portion to the deck material gutter portion of the deck material. In this case, since the upper edge portion of the lower frame side of the deck material gutter portion is disposed at least at a position lower than the base portion, the drainage of the base portion flows forward, flows down to the deck material gutter portion, and flows to the base portion. Will not be stored. On the other hand, since the deck material gutter is formed at the lower frame side of the deck material, if the upper edge of the deck material gutter is lowered, the deck material can be arranged at a relatively high position. Therefore, the upper surface (floor surface) of the deck material can be disposed at substantially the same level as the upper end surface of the lower frame.

In this case, the deck material has a hollow portion at least at a portion on the lower frame side, and the deck material gutter portion is formed by removing a part of the portion that comes into contact with the lower frame at the hollow portion. Is preferred.

According to this structure, if the deck material itself has a hollow portion, the deck material gutter portion can be formed very simply by simply removing the upper portion of the portion that comes into contact with the lower frame of the hollow portion. can do.

In these cases, the drainage of the outdoor half of the base portion is guided to the deck gutter, and the drainage of the indoor half portion passes through the hollow portion of the lower frame formed below the base portion to be joisted. It is preferable that a joist gutter part for receiving drainage from the hollow portion is formed in the joist.

According to this configuration, the flow distance of the wastewater flowing on the base portion can be reduced, so that the storage of the wastewater on the base portion can be reduced as much as possible.
That is, the drainage received in the base portion can be divided into two and efficiently guided to the deck material gutter portion and the joist gutter portion. Also, since drainage from the hollow portion of the lower frame is received by the joist gutter portion formed on the joist, leakage of water (drainage) from the deck-like structure can be effectively prevented.

In this case, it is preferable that a front wall portion of the joist gutter portion projects forward from a contact portion between the deck material gutter portion and the lower frame.

According to this configuration, even if the drainage of the outdoor half of the base leaks from the contact portion between the deck material gutter and the lower frame, this can be received by the joist gutter. In this respect, water (drainage) leakage from the deck-like structure can be effectively prevented.
