The purpose of the present invention is to provide a wall panel mounting structure that can be used for mounting a wall panel.

[0008] The wall panel referred to in the present invention is
This does not simply mean panel-shaped items, but also accessories that are usually installed on external walls, such as box-shaped window units with windows as described below, balcony units that integrate external wall panels and balconies, etc. This also includes equipment that is unitized into panels.

[0009]

[Means for Solving the Problems] In the wall panel mounting structure of the present invention, a plurality of wall panel guide rail and fixed shaft assemblies are installed vertically on the outer peripheral surface of a building frame. The fixed shaft assembly that also serves as a guide rail is attached to the support bracket provided at the end of the floor of each floor and is erected from the ground to the rooftop, and the fixed shaft assembly that also serves as a guide rail for each wall panel corresponds to the width of the wall panel. The wall panel is set at a predetermined interval and is placed between two wall panel guide rails and a fixed frame.
The fixing bracket provided at the corner on the back of the wall panel is engaged with the two wall panel guide rail/fixing frame assemblies, and the two wall panel guide rail/fixing frame assemblies The outer wall of the building is formed by being clamped and fixed using fixing bolts provided on the fixing fittings.

0010

[Operation] The fixing fittings provided on the back of the wall panel are engaged with the wall panel guide rail/fixing shaft assembly, and the wall panels are sequentially lifted upward and the wall panels are fixed in order as the wall panel guide rail/customer. Fixed to the frame.

[0011] As a result, the fixed shaft assembly that also serves as a wall panel guide rail serves both as a guide rail for the wall panel and as a fixed shaft assembly for the wall panel. Therefore, it is possible to form an outer wall of a building that has good workability, shortens the construction period, and has high installation accuracy.
