DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, a balcony A according to an embodiment of the present invention will be described with reference to the drawings. In the following description, the same reference numerals in different drawings indicate parts having the same functions, and duplicated descriptions in each drawing will be omitted as appropriate. In addition, in FIG. 1, the width direction is the left-right direction, and in FIG. 2, the projection direction is the front-rear direction.

[0010] As shown in Figs. 1 to 3, the balcony A is of a pillar-supported type, installed at a height corresponding to a window b1 provided at a high position on a structure b. The balcony A comprises a balcony main body A1 consisting of a floor panel 1 and a floor panel support 2, and a water receiving panel 3 and a water receiving panel support A2 (described below) provided under the floor of the balcony main body A. The balcony main body A1 is erected on the ground GL as shown in Figure 1, with girders e (floor panel supports 2) erected on the left and right pillars d (floor panel supports 2), and gable beams f (floor panel supports 2) erected on the left and right sides so as to span between the pillars d and the main body b. In addition, multiple vertical lattices c2 are erected between the top board c1 and the girder e and end beam f, and are arranged on three sides except for the side of the main body b.

[0011] As shown in FIG. 3, the floor panel 1 has a plurality of panel materials 1a formed long in the left-right direction, and these panel materials 1a are arranged in the front-rear direction. The floor panel 1 is supported by a floor panel support body 2, as shown in FIGS. The floor panel support 2, which will be described in detail later, includes end supports 2a that support the ends of the floor panel 1, intermediate supports 2b that support the intermediate portion of the floor panel 1, a joist support e1 provided on the inner side of the girder e, a joist hanger e2 provided on the main body b, and left and right supports d.

[0012] As shown in Figs. 5 to 7, the end support material 2a is a girder e and a girder trough 20a provided on the inner periphery of the girder e, and an end beam f and a girder trough 21a provided on the inner periphery of the end beam f. The end support material 2a supports the floor panel 1 by placing and fixing three ends of the floor panel 1 except for the end on the main body b side, and also serves as a drainage path RA that receives water flowing over the upper surface of the floor panel 1 and flowing down from the end of the floor panel 1. In addition, the girder gutter 20a may be a separate body from the girder e or may be formed integrally therewith, and the end gutter 21a may be a separate body from the end beam f or may be formed integrally therewith. The drainage path RA is connected to a drainage path RB, which will be described later, so that the water in the drainage path RA is transferred to the drainage path RB. (Limitation) Further, the drainage path RA and the drainage path RB are not limited to being connected to each other, and may be independent of each other.

[0013] The intermediate support member 2b is a joist installed between the girder e and the structure b, as shown in Figures 5 and 6. The intermediate support member 2b is installed between the joist support e1 provided on the inner periphery of the girder e and the joist hanger e2 provided on the structure b. There are a plurality of intermediate support members 2b, which are arranged in parallel at predetermined intervals in the left-right direction.

[0014] As described above, the balcony body A1 has the drainage route RA and receives water that flows over the upper surface of the floor panel 1 and flows down from the end of the floor panel 1. Normally, a balcony with only a drainage path RA is sufficient, but when you want to more reliably prevent water from falling between the floor panels 1, particularly when you want to hang laundry under a balcony built on pillars, a drainage path RB can be provided to collect water that leaks between the floor panels 1 by attaching the next water receiving panel 3 and water receiving panel support A2. In other words, whether or not to attach the water receiving panel 3 and the water receiving panel support A2 can be freely selected depending on the usage of the balcony.

[0015] The above-mentioned balcony main body A1 is provided with a water receiving panel 3 and a water receiving panel support A2 for receiving water leaking from between the floor panels 1, as shown in Figs. The water receiving panel 3 is supported by the water receiving panel support member A2, is located below the intermediate support member 2b, covers the lower surface of the floor panel 1, and is disposed so as to communicate with the drainage path RB. The water receiving panel 3 has a plurality of panel materials 3a whose longitudinal direction is the front-rear direction, and is configured by arranging the plurality of panel materials 3a in the left-right direction and connecting adjacent panel materials 3a to each other. The water receiving panel 3 is fixed by screws to the underside of a base material 3b which is fixed to the underside of the intermediate support material 2b at the connection portions of the panel materials 3a. The base material 3b has a longitudinal direction that is oriented in a left-right direction and intersects with the longitudinal direction of the middle support material 2b. A rib 3c is provided on the upper surface of the panel material 3a, with the longitudinal direction extending in the front-rear direction. In addition to reinforcing the panel material 3a, the ribs 3c are also configured so that when the water receiving panel 3 receives water flowing down from the floor panel 1, the water can be guided to the drainage path RB along the longitudinal direction of the ribs 3c. The underside of the panel material 3a is made flat all over so that there are no irregularities on the underside of the water receiving panel 3, and when looking up from below the balcony A, the floor panel 1, the intermediate support material 2b, the base material 3b and part of the drainage path RB are not visible. This allows for a good design of the area visible from below balcony A.

[0016] The water-receiving panel support body A2 has a reinforcing girder 4 and a water-receiving side girder gutter R2 attached below the girder e side, a water-receiving side end gutter R3 attached below the end beam f side, a water-receiving side structure gutter R4 on the structure b side, a diagonal brace 5 for reinforcing the water-receiving panel, and a base material 3b attached to the intermediate support material 2b. The water receiving panel support A2 is disposed below the floor panel support 2, covers the underside of the floor panel 1, and supports the water receiving panel 3 which receives rainwater flowing down from between the floor panels 1. The drainage path RB receives rainwater that is placed on the water receiving panel 3 and flows down from the end of the water receiving panel 3, and as shown in Figures 4 to 7, consists of a water drainage guide R1 provided on the underside of the gutter 21a near the corner between the girder e and the end beam f, a water receiving side gutter R2 on the girder e side, a water receiving side gutter R3 on the end beam f side, a water receiving side structure gutter R4 on the structure b side, a water collector R5 provided at the left and right corners between the girder e and the end beam f, and a drainage pipe R6. The water-receiving side girder gutter R2 on the girder e side, the water-receiving side end gutter R3 on the end beam f side, and the water-receiving side structural gutter R4 on the structural body b side are arranged so as to communicate with the peripheral ends of the water-receiving panel 3.

[0017] As shown in Figures 5 and 7, the water drainage guide R1 is connected to the gutter 21a and is positioned directly above the water collector R5 so that water from the gutter 21a passes through the water drainage guide R1 and flows down to the water collector R5.

[0018] As shown in FIG. 7, the water-receiving side girder gutter R2 is provided on the inner peripheral side of the reinforcing girder 4 which is fixed to the underside of the girder e by means of screws. The water-receiving side girder gutter R2 is fixed to the reinforcing girder 4 from the inner side by screwing, and the end of the water-receiving panel 3 is placed on the upper end of the open portion R20 of the water-receiving side girder gutter R2 so as to receive water guided from the water-receiving panel 3. The water receiving side girder gutter R2 is connected so that its left and right ends communicate with the water collector R5, respectively, so that the water in the water receiving side girder gutter R2 flows into the water collector R5. The reinforcing girder 4 is engaged from below with a reinforcing girder mounting fixture 4a that is fixed to the underside of the girder e by screwing, and is also fixed to the reinforcing girder mounting fixture 4a by screwing from the inner circumferential side.

[0019] As shown in Figs. 5 and 6, the water-receiving side gutter R3 is provided below the gutter mounting fixture 4b which is fixed to the lower surface of the end beam f by screwing. The water receiving side gutter R3 engages with the gutter mounting fixture 4b from below, and is fixed to the reinforcing beam mounting fixture 4a by screws from the inner periphery side. The gutter mounting fixture 4b is fixed by screws from the underside and inner periphery side of the gable f.

[0020] As shown in FIG. 7, the water-receiving side body gutter R4 is fixed to the outer wall b2 of the body b by screws from the inner periphery of the water-receiving side body gutter R4 toward the outer wall of the body. The left and right ends of the water-receiving side body gutter R4 are connected to the left and right water-receiving side end gutter R3, respectively, so that water from the water-receiving side body gutter R4 flows into the water-receiving side end gutter R3.

[0021] As shown in Figures 5 and 7, the water collector R5 is connected to a drain pipe R6 provided along the support d, and is configured to receive water flowing down from the water drainage guide R1 and water flowing from the gutter R3. The water received in the water collector R5 is drained to the outside through a drain pipe R6.

[0022] Such a drainage path RB can receive water flowing from the water receiving panel 3 by placing the peripheral ends of the water receiving panel 3 on the open portion R20 of the water receiving side girder gutter R2, the open portion R30 of the water receiving side end gutter R3, and the open portion R40 of the water receiving side body gutter R4. In addition, the drainage path RB is connected around the entire circumference of the water-receiving panel 3 by the water-receiving side gutter R2, the water-receiving side gutter R3, and the water-receiving side body gutter R4 of the reinforcing girder 4 provided on all four sides.

[0023] The balcony A configured as described above includes a balcony main body A1 having the same configuration as the existing balcony 100 (see FIG. 8), and a water receiving panel 3 and a water receiving panel support body A2 are attached to this balcony main body A1. In other words, the present invention is not limited to a balcony having the water receiving panel 3 and the water receiving panel support A2 from the beginning of manufacture, but can also be installed on an existing balcony 100 later.

[0024] Here, drainage of water on the floor panel 1 of the existing balcony 100 will be described with reference to FIG. 8 (see arrow). The configuration of the existing balcony 100 is the same as that of the balcony main body A1 of the balcony A in this embodiment, so a detailed explanation will be omitted by assigning the same reference numerals as those of the balcony main body A1. Water on the floor panel 1 of the existing balcony 100 flows down into the gutter 20a and the gutter 21a, and the water that flows down flows through the gutter 20a and the gutter 21a and is transferred from the gutter 20a and the gutter 21a to the drain pipe R6 via the water collector R5 and is drained away. In this existing balcony 100, water on the floor panel 1 of the balcony main body A1 may flow down directly below the floor panel 1 through gaps between the multiple panel materials 1a that constitute the floor panel 1.

[0025] This problem of water flowing directly below the floor panel 1 of the existing balcony 100 can be solved by attaching a water receiving panel support A2 and a water receiving panel 3 to the existing balcony 100. That is, water flowing down between the multiple panel materials 1a constituting the floor panel 1 of the balcony A in this embodiment can be received by the water receiving panel 3. The drained water received by the water-receiving panel 3 is guided in the front-to-back direction (see forward arrow in Figure 9) between the ribs 3c (see Figure 4) as shown in Figure 9, and is led to the water-receiving side girder gutter R2 and the water-receiving side structure gutter R4, and flows into the water-receiving side girder gutter R2 and the water-receiving side structure gutter R4. The water that flows into the water-receiving side girder gutter R2 and the water-receiving side body gutter R4 is guided in the left-right direction (see the left-right arrows in Figure 9) by the water-receiving side girder gutter R2 and the water-receiving side body gutter R4 and flows into the water-receiving side end beam gutter R3. Water that flows into the water-receiving side gutter R3 flows into the water collector R5 and is drained from the water collector R5 to the outside through the drain pipe R6 (see the downward arrow in Figure 9). In other words, even if water on the floor panel 1 flows down through the gaps in the floor panel 1, the water that flows down is received by the water receiving panel 3, and the water receiving panel 3 that receives the water can guide it to the gutter R2 and the water receiving side structure gutter R4. Furthermore, even if water that flows into the girder gutter 20a and the girder gutter 21a overflows and flows down, the water receiving panel 3 can receive this water and guide it to the girder gutter R2 and the water receiving side body gutter R4.

[0026] Therefore, water flowing down from above the floor panel 1 can be drained and rainwater leaking from between the floor panels 1 can be prevented from flowing down, providing a balcony with a structure that does not allow rainwater to affect areas below the balcony. Furthermore, since the balcony main body A1 has the same configuration as the existing balcony 100, the existing balcony 100 can be converted into the balcony A of this embodiment by attaching a water receiving panel 3 and a water receiving panel support A2 to the existing balcony 100 as necessary.

[0027] The balcony A of this embodiment is not limited to being equipped with a water receiving panel 3 and a water receiving panel support A2 attached as described above from the beginning of manufacture, but the water receiving panel 3 and the water receiving panel support A2 can be installed on an existing balcony 100 as described above. Hereinafter, a manufacturing method for a balcony A in which a water receiving panel 3 and a drainage path RB are attached to an existing balcony 100 will be described with reference to FIG. Due to the above-mentioned configuration of the balcony A, the installation work for the water receiving panel 3 and the drainage path RB can all be carried out from the underside of the floor panel 1, girder e, and end beam f without removing the floor panel 1.

[0028] First step: As shown in FIG. 10(a), a water-receiving side skeleton gutter R4 is attached to a predetermined portion of the outer wall b2 (see FIG. 7) of the skeleton b. Second step: The existing drain pipe R6 connected to the gutter section 2a is cut to a predetermined length, the connection side is removed, and the water drain guide R1 is connected to the position where the drain pipe R6 was connected (see FIG. 5). Third step: As shown in FIG. 10(b), the end gutter mounting fixture 4b (see FIG. 5) is attached to the underside of the end beam f, and the water-receiving side end gutter R3 is attached via the end gutter mounting fixture 4b. Third step: As shown in FIG. 10(c), the base material 3b is laid between the water-receiving side end gutters R3 and fixed to the lower surface of the middle support material 2b. Fourth step: As shown in FIG. 10(d), a reinforcing girder mounting bracket 4a (see FIG. 5) is attached to the underside of the girder e, and the reinforcing girder 4 is attached via the reinforcing girder mounting bracket 4a. In addition, a water-receiving side girder gutter R2 is attached to the reinforcing girder 4. The water-receiving side girder gutter R2 is not limited to being separate from the reinforcing girder 4, and may be integral with the reinforcing girder 4. Fifth step: Attach the water collector R5 to the water receiving side gutter R3 and connect it to the drain pipe R6 that has been cut and remains on the support d (see Figure 5). The drain pipe R6 in the second and fifth steps may be an existing one connected to the existing gutter portion 2a, or a new drain pipe R6 may be used in place of the existing one.

[0029] Sixth step: As shown in Figure 10(e), the water receiving panel 3 is attached to the base material 3b, and the peripheral edges of this water receiving panel 3 are placed on the respective openings R20, R30, and R40 of the water receiving side girder gutter R2, the water receiving side end beam gutter R3, and the water receiving side structure gutter R4 (see Figures 5 to 7). In this sixth step, the panel materials 3a of the water receiving panel 3 are attached in sequence from either the left or right water receiving end beam gutter R3 side. Specifically, the first panel material 3a is placed on the respective open portions R20, R30, and R40 of the water receiving side gutter R2, the water receiving side gutter R3, and the water receiving side body gutter R4 on one side of the water receiving side gutter R3, and the end portion on the other side of the water receiving side gutter R3 is attached to the base material 3b by screwing. Then, the panel materials 3a are connected in sequence toward the water receiving side gutter R3 on the other side. Specifically, the panel material 3a is placed on the open portion R20 of the water-receiving side gutter R2 and the open portion R40 of the water-receiving side body gutter R4, and is connected to the panel material 3a placed and fixed on the water-receiving side gutter R3 side, and the other end portion on the water-receiving side gutter R3 side is attached to the base material 3b by screwing. This is done sequentially, and the last panel material 3a is placed on the open parts R20, R30, and R40 of the water-receiving side gutter R2, the water-receiving side gutter R3, and the water-receiving side body gutter R4 on the water-receiving side gutter R3 side, and the end portion on one side of the water-receiving side gutter R3 is attached to the base material 3b by screwing.

[0030] By carrying out the above-mentioned first to sixth steps, the drainage route RB can be installed in the existing balcony 100 having the drainage route RA. When manufacturing a new balcony A equipped with a water receiving panel 3 and a water receiving panel support A2, a balcony body A1 having the same structure as an existing balcony (structure excluding the water receiving panel 3 and the water receiving panel support A2) is manufactured before the above-mentioned steps 1 to 6, and then steps 1 to 6 are carried out after this manufacturing. In addition, balcony A can be applied to either a garden-mounted type installed on the ground on the first floor, or a roof-mounted type installed on the roof.

[0031] The above describes in detail an embodiment of a balcony according to the present invention with reference to the drawings, but the specific configuration is not limited to these embodiments, and design changes that do not deviate from the gist of the present invention are also included in the present invention.

[0032] Furthermore, the above-described embodiments can be combined by utilizing each other's technologies, so long as there are no particular contradictions or problems in the purpose, configuration, and the like. [Explanation of symbols]
