The base portion that constitutes the waterproof unit is formed by attaching a plate material to the upper surface of the base portion main body. The base main body is formed by combining a plurality of members with slopes. As a result, a water gradient is formed on the surface of the plate material in the waterproof unit.

Japanese Patent Application Laid-Open No. 2020-20121

As in the waterproof unit of Patent Document 1, when forming a water gradient by a gradient applied to the member itself that supports the plate material, processing to secure a predetermined gradient angle and construction to arrange the member at a predetermined position High precision is required. That is, the processing and construction management for securing the water gradient are complicated.

SUMMARY OF THE INVENTION An object of the present invention is to provide a balcony capable of ensuring a desired water gradient with a simple configuration.

The balcony of the first aspect includes two cantilever beams protruding from the frame of the building, a truss beam bridged over the ends of the two cantilever beams, and between the two cantilever beams. , a plurality of inner brackets fixed to the outer peripheral surface of the building, a plurality of outer brackets fixed to the truss girder at different heights from the inner brackets, the inner brackets and the outer brackets and a floor panel supported by.

In the balcony of the first aspect, a truss beam spans two cantilever beams. A truss beam can suppress deflection compared to a beam having the same amount of members. Therefore, intermediate beams between the cantilever beams can be omitted.

Omitting the intermediate beams reduces the structure that can support the floor panels, but in this balcony, multiple inner and outer brackets are provided between the cantilever beams. Thereby, the floor panel can be supported without using intermediate beams.

In addition, the inner metal fittings and the outer metal fittings that support the floor panel are fixed at positions with different heights. Thereby, a water gradient can be formed in the floor panel. That is, it is possible to secure a desired water gradient with a simple configuration of inner and outer metal fittings having different heights.

In the balcony of the second mode, in the balcony of the first mode, the installation surfaces on which the floor panel is installed in the inner metal fittings and the outer metal fittings are sloped at an equal angle.

In the balcony of the second aspect, the installation surfaces of the inner bracket and the outer bracket are sloped at an equal angle. Therefore, rattling is less likely to occur between these hardware and the floor panel.

A balcony according to a third aspect is the balcony according to the first aspect or the second aspect, wherein the floor panel comprises a frame-shaped frame formed by combining steel materials, and a face member arranged on the upper surface of the frame. ing.

In the balcony of the third aspect, the floor panel is formed by combining a frame-shaped frame and a panel. Therefore, the frame and the face member mutually stiffen each other, so that the surface rigidity of the floor panel can be increased.

A balcony of a fourth aspect is the balcony of the third aspect, wherein the frame has a recess on the underwater side that is smaller than the other part due to the steel material, and the floor panel is notched above the recess. A drain pipe is connectable to the recess.

In the fourth aspect of the balcony, the frame is formed with a concave portion to which the drain pipe can be connected. That is, the concave portion to which the drain pipe can be connected is integrated into the floor panel. As a result, it is not necessary to process the members at the construction site of the building to form a recess for connecting a drain pipe, for example.

According to the present invention, a desired water gradient can be secured with a simple configuration.

<Balcony>
In FIG. 1, the main members forming the balcony 20 are depicted in perspective view. Balcony 20 is a structural member that includes a cantilevered slab 22 . "Cantilever" refers to a structure in which one end is fixed and the other end is free. The cantilever slab 22 in this embodiment is a flooring material having one end in the depth direction of the balcony 20 fixed to a building (not shown) and the other end being a free end.

The cantilever slab 22 protrudes to the outside of the building 10 while being supported by two pillars 12 arranged along the outer peripheral surface of the building and beams 14 bridged between the pillars 12 adjacent to each other.

The cantilever slab 22 includes two cantilever beams 24 , a truss beam 26 , a bracket 30 and a floor panel 40 . Although the floor panel 40 is formed by joining a frame 42 and a face member 44 to each other, they are shown separately in FIG.

Also, the balcony 20 is formed by fixing a handrail above the cantilever slab 22, but the illustration of the handrail is omitted in each figure.

(column, beam)
As shown in FIG. 2, the pillar 12 is a structural framework of a building made of square steel pipes. In addition, in FIG. 2 , illustration of a portion of the column 12 other than the portion where the cantilever beam 24 is joined is omitted.

A steel beam 14 spans the column 12 . The longitudinal direction of the balcony 20 is the direction along which the beams 14 extend. The beams 14 are made of channel material, as also shown in FIG.

Although the pillars 12 and the beams 14 are shown exposed in each figure, the pillars 12 and the beams 14 are hidden inside the outer wall of the building (not shown). Also, if the building is made of wood, the pillars 12 and beams 14 may be made of wood.

(cantilever beam)
The cantilever beam 24 is joined to the column 12 via a joint member 24A. The joint member 24A is a channel of steel with flange ends welded to the post 12 and the cantilever beam 24 bolted to the web to secure the cantilever beam 24 to the post 12 .

The cantilever beam 24 is a rectangular parallelepiped steel material, and one side in the longitudinal direction of the balcony 20 is open. One open surface is the surface facing the adjacent cantilever beam 24 . A fixing member 24B is fixed to the cantilever beam 24 for joining a frame 42 (see FIG. 1, etc.), which will be described later. The fixing member 24B is a crank-shaped bent steel plate.

(truss beam)
As shown in FIG. 3, the truss girder 26 is formed with upper chord members 26A, lower chord members 26B, bundle members 26C and diagonal members 26D. The upper chord member 26A and the lower chord member 26B are members extending along the longitudinal direction of the balcony 20, and arranged adjacent to each other in the vertical direction.

The bundle members 26C are members that connect the upper chord members 26A and the lower chord members 26B, and are arranged in plurality along the longitudinal direction of the balcony 20 at predetermined intervals. The diagonal member 26D is a member that extends diagonally from the upper chord member 26A to the lower chord member 26B between the bundle members 26C adjacent to each other.

Both ends of the truss beam 26 along the longitudinal direction of the balcony 20 are fixed to the tips of the cantilever beams 24 respectively. In this embodiment, an intermediate beam along the depth direction of the balcony 20 is not provided at the intermediate portion of the truss beam 26 .

(receipt)
Receiver 30 includes an inner receiver 32 and an outer receiver 34 . As shown in FIG. 2, the inner bracket 32 is joined to the beam 14 via a joint member 32A. The joint member 32A is a channel material made of steel, and the end of the flange is welded to the beam 14, and the inner bracket 32 is fixed to the beam 14 by bolting the inner bracket 32 to the web.

As shown in FIG. 3, the outer brackets 34 are bolted to each of the bundles 26C of the truss beam 26. As shown in FIG. Thereby, a plurality of outer receiving metal fittings 34 are arranged at predetermined intervals along the longitudinal direction of the balcony 20 .

As shown in FIG. 5, in the longitudinal direction of the balcony 20, the outer metal fittings 34 and the inner metal fittings 32 are arranged at the same position (on the reference lines X1, X2, X3). That is, a plurality of inner receiving metal fittings 32 are also arranged at predetermined intervals along the longitudinal direction of the balcony 20 .

In addition, as shown in FIG. 4, the inner metal fittings 32 and the outer metal fittings 34 are arranged at different heights. Specifically, the outer bracket 34 is arranged at a position lower than the inner bracket 32 . 4 is a cross-sectional view taken along line AA in FIG.

Upper surfaces 32U and 34U of the inner metal fitting 32 and the outer metal fitting 34 are installation surfaces on which floor panels 40, which will be described later, are installed. Upper surfaces 32U and 34U are sloped at equal angles.

This gradient is a gradient that slopes downward from the beam 14 side toward the outdoor side in the depth direction of the balcony 20 . Also, this slope is a slope of an angle equal to the water slope formed on the floor panel 40 . Furthermore, the upper surfaces 32U and 34U are formed on the same plane. In other words, the upper surface 34U is arranged on the extension line L of the upper surface 32U.

At least a portion of a joint surface 24BH, which will be described later, of the fixing member 24B of the cantilever beam 24 is arranged above the extension line L. As shown in FIG.

As shown in FIGS. 4 and 5, the fixed frame 22A is formed by the cantilever beam 24, the truss beam 26, and the bracket 30 described above. A floor panel 40, which will be described below, is fixed to the fixed frame 22A.

(floor panel)
As shown in FIG. 6, the floor panel 40 is formed including a frame 42 and a panel 44. As shown in FIG. When constructing the floor panel 40, the panel 44 may be fixed to the frame 42 after the frame 42 is installed on the fixed frame 22A. Alternatively, after fixing the face member 44 to the frame 42, the frame 42 may be installed on the fixed frame 22A.

The frame 42 is formed in a frame shape by combining steel materials. Specifically, the frame 42 includes frame members 42A and 42B, joist members 42C, and recesses 42D.

The frame members 42A and 42B are steel members along the longitudinal direction of the balcony 20 . Of these, the frame member 42A is fixed to the inner receiving metal member 32. As shown in FIG. On the other hand, the frame member 42B is fixed to the outer metal fitting 34. As shown in FIG.

The floor joist 42C is a member along the depth direction of the balcony 20 and spans the frame members 42A and 42B. A plurality of floor joists 42C are provided at predetermined intervals along the longitudinal direction of the balcony 20 . A member of the floor joist 42C arranged at the end in the longitudinal direction of the balcony 20 is fixed to the joint surface 24BH of the fixing member 24B.

The recessed portion 42D is arranged at a corner portion of the frame 42 (an end portion in the longitudinal direction of the balcony 20 and a corner portion on the tip side in the depth direction of the balcony 20), and has a smaller "thickness" than the steel material forming the other portions. It is a part formed by assembling steel materials into a frame shape.

The frame members 42A and 42B, the joist member 42C, and the steel members forming the recess 42D may be light steel frames, for example. Alternatively, these members may be made of wood instead of steel.

The face material 44 is a plate material formed using a particle board, structural plywood, or the like, and has an outer shape that substantially matches the outer shape of the frame 42 in a plan view. A notch 44V is formed in a portion of the face member 44 located above the recess 42D. Note that the face material 44 may be formed using an ALC panel or the like.

As shown in FIG. 7, a drain pipe 50 can be connected to the recess 42D. Specifically, a base material 52 having through holes formed therein is placed in the recess 42D. A drain member 54 to which the drain pipe 50 is connected is fitted in the through hole of the base material 52 .

A waterproof sheet 56 is laid over the base material 52 and the face material 44 . The waterproof sheet 56 is pressed downward by a drain cap 58 . In addition, the waterproof sheet 56 may be pressed downward by the drain member 54 .

Furthermore, a cover material 60 is arranged in the recess 42D. The cover material 60 covers the drain cap 58 from above and is arranged in a state of being fitted into the recess 42D.

<Action and effect>
In the balcony 20 according to the embodiment of the present invention, as shown in FIG. 3, a truss beam 26 spans two cantilever beams 24 . The truss beam 26 can suppress bending as compared with a beam having the same amount of members. Therefore, intermediate beams between the cantilever beams 24 can be omitted.

Omitting the intermediate beams reduces the structure capable of supporting the floor panel 40 shown in FIG. there is Thereby, the floor panel 40 can be supported without using intermediate beams.

The beam thickness of the truss beam 26 is larger than that of beams having the same amount of members. Therefore, for example, the drainage pipe 50 can be pulled horizontally within the range of the beam height of the truss beam 26, and a water gradient can be secured. Thereby, it is easy to secure drainage performance.

Also, when a first-floor window is arranged below the balcony 20 , part or all of the shutter box provided for this window can be accommodated within the beam span of the truss beam 26 . Thereby, the design of the appearance of the building can be improved.

In addition, the inner metal fittings 32 and the outer metal fittings 34 that support the floor panel 40 are fixed at positions with different heights. Thereby, a water gradient can be formed in the face member 44 of the floor panel 40 . That is, it is possible to secure a desired water gradient with a simple configuration of the inner metal fittings 32 and the outer metal fittings 34 having different heights.

The following configuration is conceivable as a configuration for ensuring a water gradient in the floor panel 40 when the inner metal fittings 32 and the outer metal fittings 34 are arranged at the same height (comparative example).

For example, the thickness of the panel 44 itself is gradually increased or decreased in the depth direction of the balcony 20 . For example, a plurality of joist members are arranged along the length of the balcony 20 between the panel 44 and the frame 42 . The joists are of different heights. For example, a surface material for slope formation is arranged between the surface material 44 and the frame 42 . The face material gradually increases or decreases in thickness in the depth direction of the balcony 20 .

Each of these configurations is not simple compared to the configuration in which the heights of the inner bracket 32 and the outer bracket 34 are different to form a water gradient.

In this embodiment, since the outer metal fittings 34 are arranged at a position lower than the inner metal fittings 32, the water gradient is such that the outside (the truss beam 26 side) in the depth direction of the balcony 20 is under water. Although formed, embodiments of the invention are not so limited.

For example, the outer metal fittings 34 may be arranged at a position higher than the inner metal fittings 32 so that the inner side (beam 14 side) of the balcony 20 in the depth direction is under water.

In the balcony 20, as shown in FIG. 4, the upper surfaces 32U and 34U, which are the contact surfaces of the floor panel 40, of the inner metal fittings 32 and the outer metal fittings 34 are sloped at the same angle. Therefore, rattling is less likely to occur between these hardware and the floor panel 40 .

A packing (not shown) may be added between the upper surfaces 32U and 34U and the floor panel 40 as appropriate. This can enhance the rattling suppression effect. Further, by adding packing, for example, a configuration in which the upper surfaces 32U and 34U are not inclined can be adopted.

In the balcony 20, as shown in FIG. 6, a floor panel 40 is formed by combining a frame-like frame 42 and a panel 44. As shown in FIG. Therefore, the surface rigidity of the floor panel 40 can be increased by the frame 42 and the surface member 44 stiffening each other.

In the balcony 20, the frame 42 is formed with a recess 44V to which the drain pipe 50 shown in FIG. 7 can be connected. In other words, the recess 44V to which the drain pipe 50 can be connected is unitized in the floor panel 40. As shown in FIG. As a result, it is not necessary to form a recess for connecting the drain pipe 50, for example, by processing members at the construction site of the building.

In the present embodiment, the recess 44V is provided at a corner of the frame 42 (an end in the longitudinal direction of the balcony 20 and a corner on the tip side in the depth direction of the balcony 20). Embodiments are not limited to this. For example, the recess may be formed in a strip shape along the front end side of the balcony 20 in the depth direction in the frame 42 .
That is, the shape of the recess in the present invention is not particularly limited as long as it is formed on the water side of the water gradient.
