FIG. 7 is a vertical cross-sectional view showing the vicinity of the drainage port in the drainage vertical pipe of the drainage facility structure in another example of the drainage facility structure in the balcony according to the present invention.

As shown in FIG. 1, a building 1 which is a high-rise condominium or the like has a frame structure 2 made of reinforced concrete or the like.
The skeleton structure 2 has a plurality of pillars and beams (both not shown), a slab 3 (only one is shown in FIG. 1) provided in a plurality of layers, and the skeleton structure 2 of the skeleton structure 2. It is composed of a vertical outer wall 2a forming a structural outer peripheral portion. On the outer wall 2a side of the frame structure 2, a plurality of balcony units 5 (only one is shown in FIG. 1) are provided on the slabs 3 on each floor.
It is provided in a form corresponding to in the vertical direction so as to be adjacent. The balcony drainage structure according to the present invention is applied to these balcony units 5. That is, each balcony unit 5 has a floor frame 6 having a substantially horizontal plate shape provided in a shape projecting to the outside in the horizontal side of the frame structure 2 at a level position corresponding to the slab 3 on each floor. The upper surface 6d side of the skeleton 6 is formed of a waterproof mortar 6a that prevents water and the like from penetrating into the skeleton 6. In addition, on the upper surface 6d of the floor frame 6, the first water collection position DS1
Is set, and a water gradient N is formed on the upper surface 6d of the floor skeleton 6 so as to incline toward the first water collecting position DS1. Further, in the tip portion 6c, which is the edge of the floor frame 6 on the side projecting in the direction opposite to the building 1 (that is, on the left side in the drawing of FIG. 1), the parapet portion 6 is provided along the tip portion 6c.
a is provided (note that a member such as a parapet portion or a wall is appropriately provided at a side end portion (not shown) of the floor skeleton 6, that is, an end portion on the front side or the back side in FIG. . A predetermined protective fence 7 (illustrated by a one-dot chain line) is erected on the upper end 6e side of the parapet portion 6b so that a person or the like existing on the floor frame 6 does not fall accidentally.

As shown in FIG. 1, the building 1 is provided with a drainage pipe unit 9, and the drainage pipe unit 9 has a drainage vertical pipe 10 extending vertically. The drainage vertical pipes 10 are the balcony units 5 that are vertically adjacent to each other.
The pipes are connected to connect the 5 vertically,
In each balcony unit 5, a predetermined pipe position Q that is set in advance with the floor frame 6 penetrating vertically
1 (for example, in the vicinity of the outer wall 2a of the skeleton structure 2) (however, at the location where the drainage vertical pipe 10 penetrates,
The space between the drainage vertical pipe 10 and the floor frame 6 is watertight. ). Further, the lower end side of the drainage vertical pipe 10 which is not shown reaches a sewage main pipe for rainwater treatment which is not shown, and the water or the like flowing into the drainage vertical pipe 10 is not shown via the drainage vertical pipe 10. It is designed to carry water to the main sewer.
The drainage vertical pipe 10 is provided with branch pipes 11 extending substantially in the lateral direction, which are connected to the drainage vertical pipes 10 at positions corresponding to the positions of the lower surfaces of the floor frames 6 through which the drainage vertical pipes 10 pass,
The tip end side of the branch pipe 11 protrudes upward from the lower surface side of each corresponding floor skeleton 6 (however, the branch pipe 11
At the plunge point, the space between the branch pipe 11 and the floor frame 6 is watertight. ). The tip end side of the branch pipe 11 protruding into the floor skeleton 6 reaches the first water collection position DS1 set on the upper surface side of the floor skeleton 6, and the tip end side of the branch pipe 11 has the first water collection point. Water collection port 11 capable of receiving water or the like at position DS1
a is formed.

Further, in each floor frame 6, of the piping position Q1 of the drainage vertical pipe 10, a position slightly above the upper surface 6d of the floor frame 6 and at a level position higher than the first water collecting position DS1. In addition, the second water collecting position DS2 is set at a level position lower than the upper end 6e of the parapet portion 6b of the floor structure 6, and therefore, the drainage vertical pipe 10 is shown in FIGS. As described above, the pipe wall 1 of the drainage vertical pipe 10 is formed so as to correspond to the second water collecting position DS2.
There is provided a drain port 12 that penetrates through 0a. The drainage port 12 is provided with a plate-shaped mesh 13 (hence, a member through which water or the like can pass) so as to cover the drainage port 12 from the outer peripheral surface side of the drainage vertical pipe 10. An opening / closing means 15 for opening and closing the drainage port 12 from the inner peripheral surface side of the drainage vertical pipe 10 is installed. That is, the opening / closing means 15 has an opening / closing valve 15a made of a plate-like rubber member or the like which can close the drainage port 12 from the inner peripheral surface side of the drainage vertical pipe 10, and thus follows a cylindrical shape, The upper end of the on-off valve 15a is hinged to the tube wall 10a via a hinge 15b. That is, the on-off valve 15a is connected to the pipe wall 10a via the hinge 15b.
It can be rotated and moved in the direction of approaching and retracting with respect to, ie, the directions of arrows A and B in FIGS. ), The on-off valve 15a is located at a position adjacent to the pipe wall 10a by its own weight, and therefore the drain port 12 is closed along the pipe wall 10a. Further, when a predetermined amount of water pressure or the like acts on the on-off valve 15a from the outside in the direction of arrow B, the on-off valve 15a is pushed and moved in the direction of arrow B (two points in FIG. 2). The drainage port 12 is opened).

Since the building 1, its balcony unit 5 and the drain pipe unit 9 are constructed as described above, the rainwater that has fallen into each balcony unit 5 will have an upper surface 6d of the floor frame 6 of the balcony unit 5. And reaches the first water collecting position DS1 according to the water gradient N formed on the upper surface 6d of the floor skeleton 6, and the water collecting port 11a (that is, clogging) provided at the first water collecting position DS1. It flows into the water collecting port 11a) which is not in operation, so that the branch pipe 1
1, flows into the drainage vertical pipe 10 through the branch pipe 11, and is introduced into the sewage main pipe (not shown) for rainwater treatment through the drainage vertical pipe 10. In addition, inside the drainage pipe 10 and near the drainage port 12, water that drops downward from above (for example, water collected in the balcony unit 5 or the like on the upper floor) passes. However, the drainage port 12 is provided with the opening / closing means 15, and the opening / closing valve 1
Since 5a closes the drain port 12 (because the water pressure in the direction of the arrow B does not act on the on-off valve 15a), the water that falls near the drain port 12 and passes therethrough is the drain port. Jumping out of the drainage vertical tube 10 via 12 is prevented.

By the way, since the building 1 is a high-rise condominium or the like as described above, there is a long time lag between the completion of the lower floors and the completion of the upper floors. Therefore,
In particular, in the lower-floor balcony unit 5, after the lower floor is completed, the building 1 is left for a long period of time without being sufficiently managed until the building 1 is completed and a resident moves in. While left for a long period of time, dead leaves, dust, and the like fly to the balcony unit 5 on the lower floor and are deposited on the floor frame 6 of the balcony unit 5. Also,
Dead leaves, dust, and the like accumulated on the floor frame 6 flow to the first water collecting position DS1 by the flow of rainwater and the like that has fallen into the balcony unit 5 after the accumulation, and the first water collecting position DS1.
When the water reaches the water collecting port 11a provided in the, the water collecting port 11a is clogged. After the water collecting port 11a becomes clogged as described above, the rainwater that has further dropped onto the balcony unit 5 reaches the upper surface 6d of the floor frame 6 of the balcony unit 5, and the upper surface of the floor frame 6 is reached. Although the water flows toward the first water collecting position DS1 according to the water gradient N of 6d, the water collecting port 11a provided at the first water collecting position DS1 is clogged, and therefore reaches the water collecting port 11a. Almost no rainwater (or no rainwater) can flow into the branch pipe 11 through the water collecting port 11a. That is, the rainwater that has reached the upper surface 6d side of the floor structure 6 is
Will be accumulated on the upper surface 6d side.

Continuing on, the rainwater that has fallen into the balcony unit 5 is likewise accumulated on the upper surface 6d side of the floor skeleton 6, so that the level of the accumulated rainwater rises, and the rainwater is collected from the first water collecting position DS1. At a high level position, and the floor skeleton 6
The second water collecting position DS2 existing at a lower level position than the upper end 6e of the parapet part 6b is reached. That is, it reaches the drain port 12 of the drain vertical pipe 10 provided at the second water collecting position DS2 (note that the rainwater reaching the drain port 12 is the mesh 13 installed in the drain port 12).
Arrive in a way that penetrates through. That is, by allowing the mesh 13 to permeate, dust or the like flowing with rainwater does not enter the drainage port 12, and thus clogging of the drainage port 12 is prevented as much as possible. ). The rainwater reaching the drainage port 12 tries to pass through the drainage port 12 toward the inside of the drainage vertical pipe 10. That is, since the rainwater causes a predetermined water pressure F1 to act on the opening / closing valve 15a of the opening / closing means 15 installed in the drainage port 12 in the direction of the arrow B shown in FIGS. The on-off valve 15a is pushed in the direction of the arrow B to move (illustrated by the chain double-dashed line in FIG. 2) to open the drainage port 12. When the drainage port 12 is opened, the rainwater that reaches the drainage port 12 flows into the drainage vertical pipe 10 and is conducted to the sewage main pipe (not shown) for rainwater treatment via the drainage vertical pipe 10. Therefore, the rainwater collected on the upper surface 6d side of the floor skeleton 6 reaches the drain port 12 of the second water collecting position DS2 before the water level reaches the upper end 6e of the parapet part 6b, and through the drain port 12. Since the water is appropriately drained to the vertical drain pipe 10, it is possible to prevent the problem that the water level exceeds the level of the upper end 6e of the parapet portion 6b and overflows to the outside of the balcony unit 5 to pollute the outer wall of the building 1 and the like. In the opening / closing means 15 of the drainage vertical pipe 10, when the opening / closing valve 15a is pressed and moved in the direction of the arrow B, that is, when the drainage port 12 is opened, when viewed from the inside of the drainage vertical pipe 10. ,
As shown by the chain double-dashed line in FIG.
It is arranged so as to form an eaves for 2. That is, the water that drops downwards and passes through the drainage vertical pipe 10 in the vicinity of the drainage port 12 is caused by the opening / closing valve 15a arranged in a state of forming a canopy for the drainage port 12,
This is convenient because it reaches the drainage port 12 as much as possible and almost never jumps out of the drainage vertical pipe 10 from the drainage port 12.

In the opening / closing means 15 of the above-mentioned embodiment, instead of the pipe wall 10a and the hinge 15b hinged to the opening / closing valve 15a (or in combination with the hinge 15b), the pipe wall 10a and the opening / closing valve 15a are used. You may install elastic means, such as the leaf spring 30 of the form which connects 15a. That is, the opening / closing means 1
5 to the on-off valve 15a, as shown in FIG.
A leaf spring 30 having a shape connecting between a and the pipe wall 10a is provided. The leaf spring 30 applies a force to the on-off valve 15a in the direction toward the pipe wall 10a, that is, in the direction of arrow A in FIG.
When no other external force acts on the on-off valve 15a, the on-off valve 15a is pressed by the force received from the leaf spring 30 in the direction of arrow A, and accordingly against the pipe wall 10a,
The drain port 12 is closed. On the contrary, when a predetermined amount of water pressure or the like acts on the on-off valve 15a from the outside in the direction of arrow B (that is, the direction opposite to the direction of arrow A), the on-off valve 15a is a leaf spring. It moves in the direction of arrow B against the force in the direction of arrow A received from 30 (illustrated by the chain double-dashed line in FIG. 7), thus opening the drainage port 12. By installing the elastic means such as the leaf spring 30, the closing of the on-off valve 15a is further ensured by the force received from the leaf spring 30.

In the opening / closing means 15 of the above-described embodiment, the drainage port 12 may be provided with an eaves plate 35 which is an eaves member instead of the opening / closing means 15. That is, the eaves plate 35, which is a plate-shaped member, is fixedly arranged on the inner side of the drainage vertical pipe 10 at the drainage port 12 in a state of forming an eaves for the drainage port 12. Therefore, the rainwater that has reached the drainage port 12 from the outside of the drainage vertical pipe 10 smoothly flows into the drainage port 12 which is always open, so that the drainage is performed more smoothly.

Further, in the opening / closing means 15 of the above-described embodiment, packing means 31 may be provided instead of the opening / closing valve 15a and the like. That is, the packing means 31 is similar to that shown in FIGS.
As shown in FIG. 3, the main body 32 is formed by a flexible member such as rubber into a shape in which a hollow cone without a bottom surface is inverted in the lateral direction. That is, the main body 3
2 is a shape in which the tip 32a is directed toward the inside of the drainage vertical pipe 10, and the opening 32b side of the main body 32 is the drainage port 12,
The drainage vertical pipe 1 is aligned from the inside of the drainage vertical pipe 10.
It is provided by being appropriately fixed to the tube wall 10a on the inner side of 0. Further, the main body 32 is provided with a plurality of lines of cuts 33 extending from the tip 32a to the opening 32b side. Therefore, the tip 32a side of the body 32 has these cuts 33 as shown by the chain double-dashed line in FIG. It can be opened easily by using it. Therefore, the rainwater reaching the drainage port 12 from the outside of the drainage vertical pipe 10 enters the inside 32c of the main body 32 through the drainage port 12, and the rainwater entering the inside 32c is the tip of the main body 32 due to the water pressure. The side of 32a is pressed to open and flows into the drainage vertical pipe 10. Further, since the dust and the like flowing with the rainwater remain in the inside 32c of the main body 32, it is not necessary to install the mesh 13 or the like provided in the above-described embodiment in the drain port 12.

[0016]

As described above, the first aspect of the present invention is the floor skeleton 6 provided on the side of a structure such as the building 1.
And the like, and the top surface 6 of the balcony floor frame is attached to the tip part such as the tip part 6c of the balcony floor frame.
A protruding weir portion such as a parapet portion 6b protruding upward from the floor upper surface such as d is provided, and a first water collecting position such as the first water collecting position DS1 is set on the floor upper surface of the balcony floor structure, and the balcony floor structure is set. A water gradient such as a water gradient N inclining toward the first water collecting position on the floor upper surface of the floor upper surface side of the balcony floor frame higher than the first water collecting position, The second water collecting position such as the second water collecting position DS2 is set at a level position lower than the upper end such as the upper end 6e of the projecting weir,
A first drainage means such as a branch pipe 11 is provided on the balcony floor structure,
The first water receiving portion such as the water collecting port 11a of the first drainage means is installed at the first water collecting position, and the drain vertical pipe 10 is installed.
Since the second drainage means such as the above is installed in such a manner that the second water receiving portion such as the drainage port 12 of the second drainage means is arranged at the second water collection position, it is arranged at the first water collection position. If the first water receiving part of the arranged first drainage means is not clogged,
Rainwater and the like that have fallen onto the balcony flow to the first water collecting position on the floor upper surface according to the water gradient of the balcony floor frame, flow into the first draining means from the first water receiving section, and pass through the first draining means. Wastewater is treated. Also, when the first water receiving part is clogged, the rainwater, etc. that has landed on the balcony is hardly or not drained from the first water receiving part at the first water collecting position, so the floor surface of the balcony floor frame is When the rainwater and the like continue to fall on the balcony, the water level of the rainwater accumulated further rises and reaches the second water collection position, and the reached rainwater reaches the second water collection position. From the second water receiving portion of the disposed second drainage means, it appropriately flows into the second drainage means, and the wastewater is treated through the second drainage means. In other words, the rainwater collected on the floor upper surface side is appropriately drained through the second water receiving portion at a level position lower than the upper end of the protruding weir portion, so the rainwater level accumulated on the floor upper surface side is the upper end of the protruding weir portion. This is convenient because it does not overflow outside the balcony and therefore the outer wall surface of the structure outside the balcony is not polluted.

A second aspect of the present invention is the drainage vertical tube according to the first aspect of the invention, wherein the second drainage means is a drainage vertical tube 10 or the like that vertically penetrates the balcony floor frame. The second water receiving portion is the pipe wall 10 of the vertical pipe for drainage.
Since it is a drain hole such as the drain port 12 penetrating a pipe wall such as a, the drain vertical pipe is a member of one unit,
Two functions, namely, a function of draining water accumulated on the floor upper surface side of the balcony floor structure, and a rainwater collected in an upper layer of the structure above the balcony floor structure are lower than the balcony floor structure. It has both the function of transporting to. That is, in addition to the effect of the first invention, a more rational drainage facility structure in the entire structure can be realized, which is convenient.

A third aspect of the present invention is the second aspect of the present invention, wherein the closing means such as the opening / closing means 15 and the packing means 31 for closing the inside and outside of the drainage vertical pipe in the drainage hole is provided with the drainage means. Since the water pressure, such as the water pressure F1 from the outside to the inside of the vertical pipe, is provided in an open state when acting on the closing means, the inside of the vertical drain pipe falls near the drain hole. The closing means prevents the passing water from jumping out of the vertical drain pipe. That is, in addition to the effect of the second invention, careless water leakage from the drain hole to the balcony floor frame is prevented, which is convenient.

Further, a fourth invention of the present invention is the second invention, wherein an eaves member such as an eaves plate 35 is provided inside the drainage vertical pipe in a shape corresponding to the drainage hole. Therefore, the eaves member prevents as much as possible the water that falls and passes through the inside of the drainage vertical pipe near the drainage hole from jumping out of the drainage vertical pipe. That is, in addition to the effect of the second invention, careless water leakage from the drain hole to the balcony floor frame is prevented, which is convenient. Further, since the drain hole does not need to be closed by any member and can be left open at all times, the water flowing from the outside to the inside of the drain vertical tube in the drain hole is drained vertically. Can flow in smoothly against
The drainage operation on the balcony becomes even smoother.
