JP5694759B2 - House with inner balcony - Google Patents

Description

  The present invention relates to a house having an inner balcony, and more particularly to a house in which a balcony and a roof are supported by an external pillar.

  Conventionally, in order to make the balcony larger than the one supported in a cantilevered state, the piloty unit is joined to the building body, and the pillar body extends downward from the piloty frame. It has been proposed to provide a piloti balcony that is configured under the eaves (see, for example, Patent Document 1).

  By the way, such an open-type balcony is relatively open at the top so that sufficient lighting can be secured.

Japanese Patent Laid-Open No. 10-252139

  However, when the conventional open-type balcony is used in a house, the feeling of release may be too high. For example, in the case of a balcony with sufficient sunlight, there is a case where it is difficult to spend time in the summer, especially because it is hot in the summer. Therefore, it is desired to realize a comfortable outdoor space while feeling free.

  The present invention has been made in view of such circumstances, and an object thereof is to provide a house having an inner balcony that realizes a comfortable outdoor space while having a sense of freedom.

In order to solve the above-mentioned problem, the invention relating to the house 100 having the inner balcony according to claim 1 is, for example, as shown in FIG.
Balcony 1 and
A roof 3 provided on the balcony 1 and having an eaves 3a extending forward from the tip of the balcony 1,
Bei example an external pillar 5 which support the one end side of the corner portion 1a of the frontage direction of the balcony 1 and the roof 3,
The external pillar 5 comprises a lower pillar 5A joined to the lower part of the balcony floor 7 of the balcony 1, and an upper pillar 5B joined to the upper part of the balcony floor 7.
The lower column 5A and the upper column 5B are provided with a plurality of spaces in the depth direction of the balcony 1 and surrounded by the outer wall material 13, respectively.
The plurality of upper pillars 5B are formed of an angle member 21 which is bonded to the upper and lower sides of the upper pillar side surface and has a convex portion at the lower part, and a U-shaped cross-sectional shape spanning the angle member 21 is opened downward. It is connected with the upper column connecting members 11A and 11B,
The plurality of lower columns 5A are formed of an angle member 21 which is bonded to the upper side and the lower side of the side surface of the lower column and has a convex portion on the lower side, and a U-shaped cross-sectional shape spanning the angle member 21 is opened downward. It is connected with the lower column connecting members 9A and 9B,
The outer wall member 13 has a hook 23a inserted from above into a hole 9a provided in an upper and lower column connecting member located on the lower side of the upper and lower column connecting members, and the hook 23a serves as an upper and lower column connecting member. It is supported from below by a convex part provided at the lower part of the angle member 23 to be attached,
The other end of the frontage direction of the balcony 1 characterized that you have contact with the wall surface 15 provided in the direction crossing the frontage direction.

According to the invention described in claim 1, a balcony space is provided at the corner of the house 100, and the external pillar 5 provided at the corner 1 a on the one end side in the front direction of the balcony 1 allows the balcony 1 to be separated from the tip of the balcony 1. Since the roof 3 having the eaves 3a extending forward can be supported and a deep eaves can be provided, a comfortable outdoor space can be realized while providing a feeling of freedom.
In addition, the outer column 5 can be made stronger by the upper and lower column connecting members.
Further, the upper and lower column connecting members can be attached in a state where the upper and lower column connecting members are mounted on the angle member 21, and the outer wall member 13 is positioned at a predetermined height by being supported by the angle member 23. Becomes easier.

The invention according to claim 2 is, for example, as shown in FIG.
In the house 100 having the inner balcony according to claim 1 ,
The wall surface 15 extends from the balcony 1 toward the eaves 3a in the intersecting direction.

According to the second aspect of the present invention, the wall 15 extends from the balcony 1 toward the eaves 3 a, thereby widening the width of the eaves 3 a from the wall on the other end of the balcony 1. As a result, the eaves 3a on the corner 1a side extending from the eaves 3a on the other end side can be separated from the balcony 1 to the eaves 3a, and a deep eaves Since it can be provided, a comfortable outdoor space can be realized while having a sense of freedom.

ADVANTAGE OF THE INVENTION According to this invention, since a balcony and a roof can be supported by an external pillar, and a deep eaves can be provided, while providing a feeling of liberation, it is possible to provide a house having an inner balcony that realizes a comfortable outdoor space. it can.
Furthermore, the upper and lower column connecting members can be attached in a state where the upper and lower column connecting members are mounted on an angle material, and the outer wall material is positioned at a predetermined height by being supported by the angle material, thereby facilitating the work. Become.
