  As shown in FIGS. 1 (a) and 1 (b), on the balcony 1, a floor surface 3 is formed by laying plate-shaped deck materials 2 and 2 (floor materials). Further, the floor surface 3 is provided so as to protrude from the house side, and the front girder 4 is arranged in the lateral direction at the front end side of the extension, and the wife side facing the house side from both ends of the front girder 4 is arranged. In the part, the girder 5 · 6 is arranged in the front-rear direction. The balcony 1 configured in this way can be installed not only in a detached house but also in an apartment house or a facility building.

  Further, as shown in FIG. 1 (a), the front girder 4 and the end girder 5 and 6 are respectively provided with fences 7 and 7... And connect the upper ends of these fences 7 and 7. Is provided with a coping 8. In addition to providing the fences 7,..., A plate material such as a translucent panel or a punching panel may be provided.

  Further, as shown in FIG. 1 (b), the deck materials 2 and 2 are long plate materials that are long in the frontage direction. By arranging the deck materials 2 and 2 side by side in the front-rear direction, a series of floor surfaces are provided. 3 is configured. Further, the deck materials 2 and 2 are arranged on the supports 11 and 12 and the joists 13 and 13 constituting the metal mount 10.

  Further, as shown in FIG. 1 (b), below the wife girder 6 is disposed a wife side reed 18 provided with a gradient that decreases from the front side toward the rear side. As will be described in detail later, the front end portion of the wife side reed 18 communicates with the inside of the front girder 4, and rainwater or the like flowing into the front girder 4 passes through the wife side recumbent 18, 18 is led to a vertical gutter 17 connected to the rear end of 18.

Next, the configuration of the gantry 10 will be described with reference to FIG.
First, as shown in FIG. 2 and FIG. 3, the support bodies 11 and 12 are arranged such that the distal end sides of the support bodies 11 and 12 protrude forward by fixing the rear end side thereof to the building side of the building. The The two supports 11, 12 are arranged with a gap in the frontage direction, and a long horizontal member 14 is stretched around the rear ends of the two supports 11, 12. Further, a long front girder 4 is stretched over the front end portions of the two supports 11 and 12 so as to be parallel to the horizontal member 14.

  Further, as shown in FIGS. 2 and 3, on both outer sides of the two supports 11, 12, the girder 5, 6 is arranged in the front-rear direction, and the girder 5, 6 is connected to the front girder 4 and the horizontal member 14. It is passed over between. In this way, a frame body (FIG. 3) surrounded by the four sides of the front girder 4, the end girder 5, 6 and the horizontal member 14 is formed. Further, joists 13 and 13 are arranged in the front-rear direction between the two supports 11 and 12, and the joists 13 and 13 are stretched between the front beam 4 and the horizontal member 14. Further, the end portions of the front beam 4 and the end beams 5 and 6 are connected via corner blocks 15 and 16.

  As described above, as shown in FIGS. 2 and 3, the gantry 10 of the balcony is constituted by the front girder 4, the supports 11 and 12, the end girder 5 and 6, the joists 13 and 13, and the horizontal member 14. The And in this structure, the framework comprised by the front girder 4, the end girder 5 * 6, the joists 13 * 13, and the horizontal member 14 becomes a structure supported by the support bodies 11 * 12. 12 is configured to function as a strength member that supports the overall load on the balcony.

  In this way, since only the supports 11 and 12 function as strength members, the other front girders 4 and wife girders 5 and 6 need higher bending rigidity than the support bodies 11 and 12. Therefore, it is possible to reduce the weight of the front girder 4 and the wife girder 5, 6 and the like. The “metal mount 10” as used in this specification refers to a support body 11 or 12 for supporting at least the balcony floor surface that uses metal without using wood.

  Moreover, as shown in FIG. 4, the support body 11 is set as the structure which has two members, the bracket 11A fixed to the housing side of a building, and the cover material 11B fixed with respect to this bracket 11A. The bracket 11A includes a fixed plate portion 11a that is fixed to the building frame and a long arm portion 11b that is substantially U-shaped in cross section and protrudes forward from the fixed plate portion 11a. Further, the cover member 11B is formed of a long hollow member having a substantially rectangular shape in cross section. The arm portion 11b is inserted into the cover member 11B, and the cover member 11B is fixed to the bracket 11A by a fixing member 11c such as a bolt. It has become. In addition, as a specific example of the building frame to which the bracket 11A is fixed, a beam, a girder, a torso, a pillar, and the like constituting the building can be considered.

  As shown in FIG. 4, the bracket 11 </ b> A is composed of a member that can exhibit high bending rigidity such as a steel material. Thereby, it can function as a strength member which supports the load of the whole balcony. On the other hand, the cover material 11B is configured by an aluminum extruded product or the like. Thereby, the weight of the whole balcony can be reduced. Further, a fixing long hole 11d is formed on the side surface of the cover member 11B, and the fixing position and angle of the cover member 11B with respect to the bracket 11A can be adjusted using the width of the fixing long hole 11d. It has become. And by this adjustment, the setting of the overhang dimension (projection dimension) from the building skeleton as the whole support body 11 and the setting of the gradient (gradient K1 shown in FIG. 5) mentioned later can be performed now.

  Further, as shown in FIG. 4, the bracket 11A is inserted into the cover member 11B, whereby the bracket 11A and the cover member 11B are integrated, and the bracket 11A is covered with the cover member 11B. As shown in b), when the balcony 1 is looked up from the lower side, the appearance design is constituted by the cover material 11B without the bracket 11A appearing on the beam 11, and the simple appearance design. Can be realized.

  Further, as shown in FIG. 4, spacers 11f and 11g can be attached to the upper surface 11e of the bracket 11A. As a result, in a state where the cover material 11B is attached to the bracket 11A, the spacers 11f and 11g are sandwiched between the bracket 11A and the cover material 11B, so that the cover material is equivalent to the thickness of the spacers 11f and 11g. The position of the upper surface 11h of 11B is set high.

  Further, as shown in FIG. 5, in the support 11, the spacers 11f and 11g can be arranged at the rear end portion and the front end portion of the upper surface 11e of the bracket 11A, respectively, and the thickness of the spacer 11f arranged at the rear side is By setting the thickness to be thicker than the spacer 11g arranged on the front side, a slope K1 that decreases from the rear end side toward the front end side is formed on the upper surface 11h of the cover member 11B fixed to the bracket 11A. Yes.

  Further, as shown in FIG. 5, the gradient K1 can be appropriately set according to the thickness of the spacers 11f and 11g. The material of the spacers 11f and 11g is not particularly limited, and may be rubber or resin, or metal. In addition, the spacers 11f and 11g may be fixed using a fixing tool such as a bolt or using an adhesive or the like. Each spacer 11f and 11g may be formed by laminating a plurality of spacers in addition to a single sheet. In addition, the spacers 11f and 11g are configured to be placed and fixed on the upper surface 11e of the bracket 11A. For example, the spacers 11f and 11g rise from the side surface of the bracket 11A and hold the inner top surface of the cover material 11B. Many configurations can be adopted as a configuration for adjusting the height. Further, the spacers 11f and 11g may be provided on the bracket 11A side, on the cover material 11B side, that is, on the inner ceiling surface of the hollow portion of the cover material 11B.

  Further, as shown in FIG. 5, the support 12 has the same configuration as that of the support 11, but the spacer 12f is arranged only on the rear side of the bracket 12A. Thus, a gradient K2 that decreases from the rear end side toward the front end side is formed on the upper surface 12h of the cover member 12B fixed to the bracket 12A.

  Further, in the configuration shown in FIG. 5, the thickness of the spacer 12f on the support 12 side is the same as the thickness of the spacer 11f on the support 11 side. The brackets 11A and 12A of the two supports 11 and 12 are fixed to the building frame at the same height position.

  With the above configuration, as shown in FIG. 6, the height relationship among the rear end position P1, the front end position P2, the rear end position P3 of the support body 12, and the front end position P4 is the rear end position P1 · P3 (P1). And P3 are set to have the same height), the front end position P2, and the front end position P4 in this order. And by laying the deck materials 2 and 2 on the support bodies 11 and 12 that realize such a height relationship, the diagonal position of the floor surface 3 from the rear end corner portion D1 of the one side end portion is obtained. A floor gradient U1 that decreases toward the front end corner D4 of the other side end of the floor surface 3 is formed.

  Then, as shown in FIG. 6, the above-described floor gradient U1 allows rainwater and the like on the surface of the floor surface 3 to flow toward the front end corner D4, thereby realizing a configuration in which rainwater and the like can gather in one place. it can. In this way, it is possible to ensure good drainage of the floor surface 3. Furthermore, since it becomes possible to set the rear end corners D1 and D3 horizontally, a step is eliminated between the floor 3 of the balcony and the indoor floor 9 that is continuous, or the step is reduced. Or it becomes possible to make a uniform level | step difference in a frontage direction.

  As shown in FIG. 6, at the same time as the floor gradient U1 is formed, the rear end corner D1 is changed from the rear end corner D1 to the front end corner D2 in the one side end of the floor 3 (the end closer to the support 11). The girder-side slope U2 that decreases toward the front end corner D4 from the rear end corner D3 at the other end of the floor 3 (the end near the support 12). At the front end of the floor surface 3 (in the vicinity of the front girder 4), a front girder-side gradient U4 that decreases from the front end corner D2 toward the front end corner D4 is formed.

  Further, in FIG. 5, the gradients K1 and K2 are changed by changing the arrangement and thickness of the spacers 11f, 11g, and 12f, and the floor gradient U1 shown in FIG. 6 is also changed accordingly. Will be. For example, when the spacers 11f and 11g are arranged on the bracket 12A side in FIG. 5 and the spacer 12f is arranged on the bracket 11A side, in FIG. It becomes possible to form a gradient that becomes lower toward the front end corner portion D2 of the one side end portion of the floor surface 3 to be positioned.
