Description

Detailed Description of the Invention [Industrial applications]

 Concerning the drainage structure by the eave ceiling and gutter of the balcony.

[Prior art]

In the past, rainwater that infiltrates the balcony or the drainage of the outdoor unit of the installed cooler is left flowing on the balcony. In addition, drains are formed on the balcony for drainage.

[Problems to be Solved by the Invention]

Therefore, rainwater or drainage pollutes the balcony or reaches the outer wall and makes it unsightly. Further, when the drainage groove is formed, not only is it troublesome to construct, but also maintenance is difficult. The present invention has been made to solve the above problems, and its purpose is to allow rainwater to enter a balcony or drain water from an outdoor unit of a cooler to drain from a predetermined location, resulting in a good appearance. Not only that, but also to provide a balcony drainage structure that is easy to install and maintain.

[Means for Solving the Problems]

The drainage structure of the balcony of the present invention has a box-like shape in which the upper surface is open and the four sides are raised below the balcony 1 provided so as to project from the top end of the second-order beam of the outer wall W toward the front of the outer wall W. A plurality of eaves ceiling materials 2a, 2a, 2a are installed in series in series, and each eaves ceiling material 2a, 2a,
The eave ceiling 2 is formed so that the box-shaped inner bottom surface of 2a is inclined downward toward the outer wall W side, and each eave ceiling material 2a, 2a, 2a constituting the eave ceiling 2 is formed. Is provided near the outer wall W of the outer wall W in such a manner that the drainage ports 3,3,3 are arranged so as to be aligned in a direction parallel to the outer surface of the outer wall W, and communicate with the lower side of the drainage ports 3,3,3. The gutter part 4 installed in the above connects the plurality of eaves ceiling materials 2a, 2a, 2a to each other, and the above problem is solved by this configuration. [Operation] Rainwater that enters the balcony 1 or drainage of the outdoor unit of the cooler flows from the drainage port 3 of the eaves ceiling 2 to the trough portion 4 without contaminating the outer wall W, or the eaves ceiling 2 and the gutter. The drainage structure can be formed only by forming the portion 4, and the appearance is good, the construction is easy, and the maintenance is easy. [Example] The central cantilever beam 5 projects from the top end of the second-order beam of the outer wall W, and the joists 6 are bridged through the cantilever beam to form the front beam 7.
Is installed. A floor material 8 is laid on the joists 6, a pillar 9 is erected on the front beam 7, and an exterior material 10 is attached via the pillar 9. A girder makeup 11 is attached to the front surface of the front beam 7 to construct the balcony 1. In the embodiment shown in FIG. 1 and FIG. 2, a plurality of box-shaped eaves ceiling materials 2a having an open upper surface are attached to the lower surface of the balcony 1 and the eaves ceiling inclined upward toward the outdoor side. 2 is formed. A plurality of drainage ports 3 are bored on the indoor side of each eaves ceiling material 2a. Below the drainage port 3 of the eaves ceiling 2, an eaves gutter 4a is attached via a fixture 12 to provide a gutter part 4. Rainwater that has entered the balcony 1 flows through the floor material 8 from the floor joists 6 to the eaves ceiling 2, flows through the eaves ceiling 2 from its drainage port 3 to the eaves trough 4a, and then to the vertical gutter 14. Be drained. In the embodiment shown in FIG. 3, the drainage port 3 is formed by cutting out one end of the eaves ceiling material 2a that constitutes the eaves ceiling 2, and a C-shape is formed below the edge of the drainage port 3. The gutter part 4 is formed by projecting the locking piece 13 and fitting a trough member 4b having an arcuate cross section into the locking piece 13. In this case, the gutter member
4b also functions as a connecting material between the eaves ceiling materials 2a.

【The invention's effect】

According to the present invention, a plurality of eaves having a box shape having an open upper surface and four raised sides are provided below a balcony provided so as to project from the top end of the second-floor beam of the outer wall to the front of the outer wall. Since the ceiling materials are installed in series and installed, and the eave ceiling is formed so that the box-shaped inner bottom surface of each eave ceiling material is inclined downward toward the outer wall side, outdoor outdoor Rainwater that falls on the balcony installed on the balcony or drainage from the outdoor unit of the cooler installed on the balcony will be received extensively by the inner bottom surface of each box-shaped eave ceiling material. The inner bottom surface of the box-shaped eave ceiling material efficiently performs drainage reception, and the plurality of eave ceiling materials integrally serve also as the eave ceiling in the space below the balcony. Moreover, there is an advantage that a balcony and an eaves ceiling having an area of arbitrary size can be constructed by connecting a plurality of eaves ceiling materials of one unit in series. In addition, a drainage port is provided near the outer wall of each eaves ceiling material that constitutes the eaves ceiling so as to be aligned in a direction parallel to the outer surface of the outer wall, and communicates below the drainage port. By connecting the plurality of eaves ceiling materials to each other by the gutters installed as described above, it is possible that a large amount of drainage such as rainwater is generated by the box-shaped wide inner bottom surface of the plurality of eaves ceiling materials. After receiving the water, a large amount of drainage flows toward the outer wall and is concentrated in the drainage port, and is efficiently drained to the outside all at once through the gutter part, which prevents the surface of the outer wall from being contaminated by drainage. . Then, by only installing a plurality of eave ceiling materials and gutters that make up the eave ceiling, the drainage mechanism of the balcony and the eave ceiling in the space below the balcony can be easily installed, and the appearance is reduced. Not only is it good, but its maintenance is also easy.
