Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for mounting a balcony on the outer wall surface of a building.

[0002]

2. Description of the Related Art As a structure for mounting a balcony on the outer wall surface of a building, there is one disclosed in Japanese Utility Model Publication No. 55-53602, for example. In this structure, the balcony is attached by directly fixing the flange portion provided on the balcony body to the outer wall surface with bolts.

As another example, Japanese Patent Laid-Open No. 4-363428 discloses a mounting structure for mounting a flower balcony (a small balcony for placing a flower pot or the like) on the outer wall surface. In this structure, flower balconies are attached to the outer wall through arms that largely project from the outer wall.

[0004]

However, in the former prior art, since the balcony main body is directly attached to the outer wall surface, the balcony main body, which is a heavy object, is supported during the installation work until the installation is completed. There is a problem that it is necessary to perform work, and the work is difficult and dangerous. (Workability problem)

Further, the latter conventional technique has the following problems. First, the cost of the balcony is high because a relatively large member such as a brace is used. (Problem of cost) Secondly, since the balcony body and the outer wall surface are not directly joined to each other, a gap is likely to be formed therebetween, which is not preferable in appearance.
There is also the risk of leading to waterproofing problems. (Quality issue) Thirdly, considering the case where it is applied to a unit building (building in which multiple building units are manufactured in a factory, transported to the site, and then joined), the unit building method is used in the factory as much as possible. Although it is ideal and advantageous to attach it, members that largely project from the wall surface such as arms are not attached because they conflict with transportation restrictions. Therefore, they have to be attached locally, and the merit of the unit building cannot be fully utilized. (Problem of adaptability to unit building)

The present invention has been made in view of the above problems, and provides a balcony mounting structure that solves the problems of workability, cost, and quality and is also highly adaptable to unit buildings. The purpose is to do.

To fix the receiver to the outer wall surface, a screw, a nail or the like is used. Alternatively, it is preferable to use bolts and nuts in terms of strength.

The balcony is composed of a floor surface portion and a wall portion, and a floor board and a wall board are stretched on a main structural material which is a framework of the balcony. The material of each board is selected from wood materials such as plywood, inorganic materials such as cement boards, and metal materials such as aluminum boards. If necessary, the surface of the board is painted or a waterproof sheet is laid. In addition, a lattice may be used instead of the wall board.

The main structural material of the balcony is galvanized steel,
It is made of stainless steel or the like, and a frame is formed by assembling steel materials such as a U-shaped section and a square-shaped section. In the vicinity of the outer wall contact portion of the main structural member on both side walls of the balcony, a locking portion for locking the locking protrusion of the receiving member is provided. This locking portion is formed by notching the main structural material or punching out the main structural material.

Bolts and nuts are preferable in terms of strength as a penetrating fixture for fixing the main structural members on both side walls of the balcony and the outer wall surface. In general, fixing bolts and nuts requires double-sided work from inside and outside of the outer wall. In terms of work, it is desirable to work only from the outer surface.To do this, a plate with a back nut is fixed inside the outer wall, or conversely, the bolt head is fixed inside the outer wall and the screw part of the bolt is It is better to project outward from the outer wall surface.

[0012]

In the balcony mounting structure of the present invention, since the main structural members on both side walls of the balcony are locked to the receiving member fixed to the outer wall surface, it becomes stable in this state during mounting work. Since it can be temporarily placed, it is possible to securely and securely attach the balcony main body, which is a heavy object, without having to perform work while separately supporting it with human power. Therefore, the problem of workability, which is one of the problems of the conventional technology, is solved.

Further, in the balcony mounting structure of the present invention, since the main structural members of both side walls of the balcony are locked to the locking projections of the receiving member, the structure can be mounted without using a large member such as a brace. You can Therefore, the cost problem, which is one of the problems of the conventional technology, is solved.

Further, in the balcony mounting structure of the present invention, since the balcony main body and the outer wall surface are directly joined to each other, they can be mounted without forming a gap between them. Therefore, the problem of quality, which is one of the problems of the prior art, is solved.

Further, in the balcony mounting structure of the present invention, since the receiving member may be a relatively small member, even if it is attached to a building unit that constitutes a unit building at a factory, it does not violate transportation restrictions. Therefore, the problem of adaptability to a unit building, which is one of the problems of the prior art, is solved.
