Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage structure for draining water from a downspout on a floor such as a veranda or a balcony of a house. 2. Description of the Related Art Conventionally, it has been proposed to lay a unit-type floor decorative material such as a tile mat made of a synthetic resin on the floor of a balcony or veranda made of concrete or the like (for example, see, for example). JP-A-5-85929, JP-A-6-4243, JP-A-6-49633.
JP-A-9-96091). When such a unit type floor covering material is laid on the floor of a balcony or a veranda made of concrete or the like, the floor surface of the concrete can be freely covered by covering the concrete floor surface with the floor covering material. Can be decorated and produced, and the degree of freedom in design can be improved. As shown in FIG. 5, on a balcony on which a unit type floor covering material such as a tile mat is laid, rainwater from a roof is received by a rain gutter, and from a vertical gutter a to a floor b of a balcony or the like. A circular drainage hole d is formed by drilling a hole in a tile mat c as a unit-type floor decorative material laid on the floor of a balcony to form a circular drainage hole d. It is arranged to face the mouth d. In this way, drainage from the downspout a and rainwater falling on the tile mat c are formed below the tile mat c, flow on the floor b of the drainage space, and drain together with the balcony downstairs. It has become. However, in the above-mentioned drainage structure, the lower end of the vertical gutter a only faces the circular drainage port d of the tile mat c. Rainwater drained to the drain port d vigorously bounces off as shown by the arrow e, and sometimes stains the wall f. Further, when the square downspout a is used, even if it is inserted into the circular drain port d, a gap is formed in the insertion port and the connection portion is unsightly, and the rainwater drained to the drain port d from the gap bounces off the wall f. There was that. [0005] In view of such circumstances, the present invention relates to a unit floor decorative material laid on the floor of a balcony, in which a circular drain outlet is formed even when a square downspout is used. It is an object of the present invention to provide a drainage structure in a balcony in which a gap is not formed at a connection portion with a cosmetic material, the appearance is good, and splashing of rainwater is prevented. [0006] In order to achieve the above object, a floor structure according to the first aspect of the present invention comprises a downspout and a unit-type floor decorative material laid on the floor. Is connected to the floor through a drain joint, and the drain is connected. The unit floor covering material has a circular drain port formed on the surface and a leg formed on the lower surface to form a drain space, thereby forming a drain joint. Is characterized in that one connection port is formed in a circular shape that can be fitted to the drain port of the unit type floor decorative material, and the other connection port is formed in a shape that can be fitted to the downspout. And The unit-type floor decorative material of the present invention is not particularly limited, but a wooden brick may be inserted into a frame-shaped resin mat, or a resin-permeable resin mat formed by vertical and horizontal rails. It is made by bonding a decorative tile or a resin tile integrally molded with a resin mat.
A tile mat in which resin mats can be connected to each other is preferable. Embodiments of the present invention will be described below in detail with reference to the drawings showing embodiments of the present invention. 1 and 2 show an embodiment of a drainage structure in a balcony according to the present invention. As shown in FIG. 1, the drainage structure of a balcony according to the present invention is such that a plurality of unit type floor decorative materials 10 are placed on a balcony stand B, and a vertical section gutter 20 and a unit type floor decorative material are provided. 10 is connected via a drainage joint 30. [0010] The balcony mount B is fixed to the building frame C side so as to protrude outside, and the protruding mount B is surrounded on three sides by a waist wall 40, and a handrail 41 is provided at the upper end of the waist wall 40. Have been. In addition, a drain groove 51 is formed in the floor surface 50 of the balcony base B, and the drain groove 51 is provided.
A drainage channel 52 communicating downward is provided at the bottom of the drainage channel, and a distal end of the drainage channel 52 is connected to a drainage pipe 53. The unit-type floor decorative material 10 is a resin mat 1
1 is a tile mat formed by integrally molding a resin tile 12 on the upper surface, and is formed to have a size of 300 mm in length and 28 mm in thickness. Nine resin tiles 12 are arranged on the surface of the resin mat 11 in three rows and columns, and drain joints 13 are formed between the resin tiles 12. A circular drain port 14 is formed in the resin tiles 12 arranged at the corners. The tile mat 10, which is a resin floor decorative material, has legs 15 formed on the lower side, and as shown in FIG.
A drainage space 16 is formed between the floor and the balcony floor 50, and a male / female connection structure is provided on the peripheral wall (not shown). The tile mat 10 includes a drain joint 13 formed on the resin mat 11 and the tile mat 1.
Water can be drained from the gap 10 a generated when the 0s are connected to the drain space 16 on the back side of the tile mat 10. The drainage joint 30 has one connection port 31 formed in a circular shape having substantially the same diameter that can be fitted into the circular drainage port 14 of the tile mat 10, and a cutout 31 at the lower end.
1 is formed. The other connection port 32 is formed in a shape that can be fitted to the lower end of the downspout 20 having a rectangular cross section. In order to mount the plurality of tile mats 10 on the balcony floor 50 and connect the downspout 20 to the tile mats 10 in this manner, the tile mat 10 near the wall where the downspout 20 is provided is provided. The resin tile 12 is provided with a drain port 14 having the same size as the outer shape of the downspout having a circular cross section by using a forsaw. Subsequently, the connection port 32 of the drainage joint 30 is extrapolated to the lower end of the downspout 20, and
It is fitted and connected to the drain port 14 of the tile mat 10.
At this time, the square downspout 20 and the circular drain port 14 opened by the forsaw are connected by the drain joint 30 and there is no gap, so that the appearance is improved. When a downspout having a circular cross section is used, the tip of the downspout can be inserted into the drain port 14 without using the drainage joint 30. When it rains during use, the resin mat 1
The rainwater flows down to the drainage space 16 from the drainage joint 13 and the gap between the unit-type floor decorative materials 30 and the rainwater from the downspout 20 passes through the drainage joint 30 to the lower surface of the unit-type floor decorative material 10. Into the drainage space 16 of
The water flows from the balcony floor 50 to the drain 51. The rainwater flowing down the downspout 20 does not jump from the drain 14 and leak. Although the embodiment of the present invention has been described in detail with reference to the drawings, the specific embodiment is not limited to this embodiment, and a design change or the like may be made without departing from the gist of the present invention. Even if present, it is included in the present invention. For example, a notch 311 is formed at the lower end of the connection port 31 of the drainage joint 30, but as shown in FIG.
An opening window 312 may be formed on the connection port 31 side. Also,
When using a downspout having a circular cross section, the tip of the downspout having a circular cross section may be inserted into the drain port 14 without using the drainage joint 30. The other connection port 32 may have a circular shape that can be fitted to the downspout. The drainage structure for a balcony according to the present invention is constructed as described above. Therefore, a unit-type floor decorative material laid on the floor of a balcony uses a square downspout. No gap is formed at the connection part with the unit type floor decorative material with a circular drain port formed, so it looks good,
Even if there is heavy rainfall during use, the water that has flowed down from the downspout to the unit type floor covering material is surely drained from the drain port to the drainage space. Therefore, the vicinity of the wall where the downspout is provided is not contaminated by the scattered water.
