DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a balcony which is attached to a building frame so as to be continuous with a window opening.

[0002]

2. Description of the Related Art A front girder and left and right girder beams are connected in a U shape,
Pillars and rooftop balconies are known in which pillars are attached to the joints and deck materials are attached to the front spar and the left and right girder beams. In addition, there is known a take-out balcony in which a leading bracket is attached to a building frame and a beam is connected to the leading bracket.

[0003]

With the recent popularity of gardening, it has been considered to place plants on a balcony and use the balcony like a garden. As a balcony that can be used like a garden, a large balcony having a depth and a frontage longer than a conventional balcony and having a large floor area is required.

As described above, it is necessary to lengthen the front girder and the girder in order to lengthen the depth and the frontage. However, the front girder and the girder of the conventional balcony use a hollow aluminum extruded material. Due to the extrusion equipment, it is not possible to manufacture an extruded aluminum section with a large cross-sectional shape, so if the front girder and the girder beam are lengthened, the strength may be insufficient.There is a large balcony where multiple plants are placed and used like a garden. This is an obstacle to practical use.

Therefore, an object of the present invention is to provide a balcony which can solve the above-mentioned problem.

[0006]

According to a first aspect of the present invention, there is provided a balcony frame, a deck beam and a handrail attached to the balcony frame, and a girder beam forming the balcony frame.
The front spar is a balcony characterized by a truss structure in which a plurality of lattice materials are connected to an upper chord material and a lower chord material.

According to a second invention, in the first invention, an intermediate girder is connected between the left and right girder beams, and the intermediate girder is a balcony which is a truss structure in which a plurality of lattice members are connected to an upper chord material and a lower chord material. is there.

In a third aspect of the present invention, in the first aspect, the end beam comprises a frame for mounting the frame, a frame beam on the frame side, and an intermediate beam.
A connecting column, a girder beam on the front girder side, and a column are provided. Can be connected to the front spar,
Balcony that can be connected to pillars.

A fourth invention is the balcony according to the third invention, wherein an intermediate girder is connected between the left and right columns and between the left and right middle beams.

[0010]

According to the first invention, since the girder and the front girder have high strength, a large balcony with a large depth and a frontage is assembled using the long girder and the long girder. It is possible to In addition, the upper beam and the front girder can be made to have high strength by using the upper chord material and the lower chord material having a small cross-sectional shape, and the upper chord material and the lower chord material can be formed by extruded aluminum. Therefore, it is possible to assemble a balcony with a large floor area that can be used like a garden using the extruded aluminum members.

Since the girder has high strength, it is possible to lengthen the cantilever support portion (carrying-out portion) of the balcony, and in the case of a type of balcony where the girder is supported by a pillar, the pillar is constructed more than the front spar. Can be closer to the skeleton. Therefore,
When storing the car in the lower space of the balcony, it is easy to put the car in and out without the pillars getting in the way.

Further, since the front spar and the girder are supported on the pillar at two points, the upper chord material and the lower chord material, the balcony is less likely to be deformed in the left-right direction due to wind, earthquake, or the like. Therefore,
The pillars can be of small cross section, which makes the pillars less noticeable and does not detract from the appearance of the house.

According to the second aspect of the present invention, the balcony frame has higher strength by the high-strength intermediate girder, so that a balcony having a larger floor area can be assembled. Further, since the load applied to the deck material is supported by the intermediate girder, a heavy object can be placed on the deck material, and a large flowerpot or the like can be placed.

According to the third aspect of the present invention, balconies having different depths can be assembled by arbitrarily selecting the type and number of connecting beams, the number of columns, and the like.

According to the fourth aspect of the present invention, the interval between the left and right columns and the interval between the left and right intermediate beams are regulated by the intermediate girder, so that the work of assembling the balcony is easy.

When storing the car in the lower space of the balcony, it is easy to put the car in and out without the pillars getting in the way.

Further, since the front spar and the girder are supported by the pillar at the two points of the upper chord material and the lower chord material, the balcony is less likely to be deformed in the left-right direction due to wind or earthquake. Therefore,
The pillars can be of small cross section, which makes the pillars less noticeable and does not detract from the appearance of the house.

According to the second aspect of the present invention, the balcony frame has a higher strength by the high-strength intermediate girder, so that a balcony having a larger floor area can be assembled. Also, since the load applied to the deck material is supported by the intermediate girder,
Heavy objects can be placed on the deck material, and large flower pots can be placed.

According to the third aspect of the present invention, balconies having different depths can be assembled by arbitrarily selecting the type and number of the connecting beams and the number of columns.

According to the fourth aspect of the present invention, the interval between the left and right columns and the interval between the left and right middle beams are regulated by the intermediate girder, so that the work of assembling the balcony is easy.
