DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sleeve-wall balcony constructed at a corner of a building.

[0002]

2. Description of the Related Art In recent years, buildings having sleeve-wall balconies installed at corners of buildings have increased. Conventionally, as such a balcony, a bracket having a mounting piece protruding in the direction of a corner is attached to an end of a front girder abutting on a sleeve wall, such as that of Japanese Utility Model Laid-Open No. 63-174201, and inserted through the mounting piece. A balcony is known in which a bolt is screwed into a pillar inside a sleeve wall to fix a front spar to the sleeve wall. However, this is low in strength because the weight of the balcony and the load on the balcony are supported at two points: the connection between the front spar and the column and the base of the girder beam facing the sleeve wall.

Therefore, in addition to fixing the end of the front girder to the sleeve wall, another balcony has been proposed in which another girder is arranged along the sleeve wall and the tip of the girder is connected to the end of the front girder. ing. In order to construct such a balcony, a girder fixing device is attached to the outer surface of the sleeve wall, a girder beam is arranged along the sleeve wall, and then the ends of the girder are fixed to the girder fixing device and the girder fixing member is attached. Connect to the tip.

However, in this structure, it is difficult to position the attachment position of the girder fixing device to the sleeve wall, and in the case of a structure in which the girder fixing device is fitted into the end of the hollow girder from above, the appearance of the girder is improved. If sleeve walls are arranged on both sides, the girder cannot be fitted horizontally between both sleeves, so both ends of the girder should be aligned with the ends of the girder beams, and the girder fixture should be fitted inside the girder. It is very difficult to do so, so the construction is troublesome, and it is necessary to perform processing such as forming a groove for inserting a fixture in the end peripheral wall of the girder.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a sleeve wall balcony which has a gable beam on the side of the sleeve wall, is sturdy, and can easily be attached to the girder and the girder to the sleeve wall. .

[0006]

At this time, a fixing bracket having a mounting portion to the sleeve wall and a protruding piece in the front-rear direction is previously mounted on the end of the front girder on the side of the sleeve wall. The projecting piece of the fixing fitting is engaged with the tip of the girder on the sleeve wall side to temporarily place the sleeve wall side of the front girder on the girder beam, and then the mounting portion is fixed to the sleeve wall.

A positioning portion is provided at least at the end of the girder beam on the side of the sleeve wall, into which the projection of the fixing bracket is inserted and engaged. When attaching the front spar, the projection of the fixing bracket is attached to the sleeve wall side. There is a case where the mounting portion is fixed to the sleeve wall after being inserted into the tip of the beam and engaged with the positioning portion, and positioning the sleeve wall side of the front girder on the end beam.

[Device] The present invention relates to a balcony installed at a corner of a building. At least one of the right and left end beams is fixed to the outer wall on the side of the sleeve wall and arranged to face each other. Front girders are attached to the ends of the left and right girder beams. The front end of the side wall of the sleeve wall and the end of the front girder on the side of the sleeve wall are connected by a fixing metal and fixed to the sleeve wall. The fixing bracket is integrally provided with a mounting part to the sleeve wall, a front and rear projection, and a left and right front girder mounting part.The front girder mounting part of the fixing bracket is fixed to the front end of the front girder, and the protruding part is a girder beam. The mounting portion is fixed to the sleeve-wall-side outer wall by engaging with the positioning portion formed at the distal end of the sleeve.

[0009]

[Function] The process of temporarily fixing or positioning the end of the front girder on the sleeve wall side by attaching the fixing bracket to the end of the front girder on the side of the sleeve wall is as follows.
Facilitating the mounting of the front spar on the sleeve wall of the building. The structure in which at least one of the girder beams is arranged on the sleeve wall of the building, and the front girder, the girder beam and the outer wall are connected by fixing brackets, is to reduce the weight and load of the balcony by the joint between the sleeve wall and the front girder and the girder beam.

[0022]

According to the first aspect of the present invention, when a sleeve wall balcony is constructed, the end of the front girder on the side of the sleeve wall is temporarily placed at the tip of the girder on the sleeve wall, thereby reducing the load on the front girder. Since the work of fixing the end of the front spar to the sleeve wall can be performed after being released, the construction is easy and accurate. In addition, danger is reduced even when working at heights. According to the configuration of claim 2,
By temporarily placing the front girder at the tip of the girder beam, the mounting position is also determined, so that the construction becomes easier and more accurate. According to the configuration of claim 3, the construction of the sleeve wall balcony can be easily performed, and the own weight and the loading load of the sleeve wall balcony are reduced to three or four points at the attachment part of the sleeve wall and the front girder and at the base of the girder. Balcony is sturdy and secure because it can be dispersed and supported.

Since the front spar can be horizontally moved in the room direction and installed between the girder beams, it is easy to construct even when there are sleeve walls on both sides. In addition, there is no need to form a guide groove or the like at the end of the front girder for inserting a metal fitting for joining with the girder, and therefore, the members constituting the balcony can be easily processed and the manufacturing cost can be reduced.
