TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to an outer wall mounting structure for a balcony of a steel-framed house.
[0002]
[Prior art]
Conventionally, when an outer wall panel of a house is fixed to a beam, a welding structure has been employed. Specifically, as shown in FIG. 6, the mounting brackets 102 are bolted to upper left and right sides and lower left and right sides on the back side of the outer wall panel 101, respectively, while the upper flange 103a and the lower flange 103 of the beam 103 formed of H-section steel are provided. An angle iron 104 as a mounting member is welded to 103b, and a vertical portion 104a of the angle steel 104 is inserted into a gap between each mounting bracket 102 and the outer wall panel 101. Next, the mounting bracket 102 is welded to the angle steel 104 to prevent the mounting bracket 102 from rotating and coming off the angle iron 104 due to an earthquake or the like, and to prevent the outer wall panel 101 from moving horizontally with respect to the beam 103. I do.
[0003]
Note that the outer wall panel 101 is extruded and formed with a plurality of hollow portions 101a. Further, bolt holes are formed at predetermined positions in the upper left and right sides and the lower right and left sides of the rear wall side of the outer wall panel 101 to penetrate any one of the hollow portions 101a. A nut fitting (not shown) inserted from the end of the hollow portion 101a is provided in advance in the bolt hole of the outer wall panel 101. Accordingly, the mounting bracket 102 can be fixed at a predetermined position on the outer wall panel 101 by aligning the bolt hole of the mounting bracket 102 with the nut fitting provided in the bolt hole of the outer wall panel 101 and screwing the bolt.
[0004]
[Problems to be solved by the invention]
However, as described above, when welding the mounting bracket to the angle iron in order to prevent rotation of the mounting bracket, the welding operation must be performed under poor conditions of the scaffold, and the operation becomes complicated, and the welding operation is performed. A skilled technician and welding equipment capable of performing the above are required. Moreover, there is a possibility that spatters melted by the welding drop and the material is damaged or a fire may occur.
[0005]
On the other hand, it has been proposed to attach the outer wall panel of the balcony with the above-described welding structure. However, in addition to directly including the problems associated with the use of the welding structure, the back surface of the outer wall panel is exposed to the indoor side, and the appearance is improved. There is a disadvantage that it decreases. For this reason, there is a problem that makeup work for covering the back surface of the outer wall panel, for example, spray painting must be separately performed, and much work time is required.
[0006]
The present invention has been made in view of such a problem, and provides an outer wall mounting structure that can easily and securely fix an outer wall panel without impairing appearance when forming an outer wall of a balcony. Things.
