DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting an exterior plate to an outer wall surface of a skeleton, and more particularly, to a structure for mounting a connecting portion between a lower portion of an upper panel and an upper portion of a lower panel.

[0002]

2. Description of the Related Art An exterior panel is attached to an outer wall surface of a building by various methods. For example, when a large exterior plate is attached, a high supporting force is required due to its weight, so a dry construction method capable of structurally supporting the exterior plate is employed.
In the dry method, generally, fittings having a positioning adjustment function capable of adjusting the dimensions of entering and exiting from the outer wall surface of the skeleton and the height dimension of the left and right panels are used. For example, in a case where the metal fitting is composed of a metal fitting and a metal fitting, the metal fitting is embedded in the exterior plate, and the metal fitting is fixed to the support frame fixed to the skeleton side by welding. Then, the fixing metal fitting and the mounting metal fitting are adjusted and engaged so that the entrance and exit dimensions from the skeleton and the joints of the exterior plates match, and the exterior plate is mounted at a predetermined position on the outer wall surface of the skeleton.

[0003]

However, in the above-mentioned dry method in which the mounting bracket is engaged with the fixing bracket, for example, it is very difficult to mount the exterior plate. That is, generally, the outer panel is carried to the mounting position of the outer wall of the skeleton by a crane, and is sequentially mounted upward from the lower part of the outer wall, but fixed while matching the entrance and exit dimensions and joints of the upper and lower adjacent outer panels. A great deal of labor and time was spent engaging the fittings with the fittings. In addition, fixing the fixing bracket to the support frame by welding is extremely poor in workability because it involves many work at high places. Further, when the mounting bracket is embedded in the outer plate, the structure of the outer plate becomes complicated, and the number of manufacturing steps is increased. The present invention has been made in view of the above circumstances, does not require burying a metal fitting in an exterior panel, does not require metal welding when mounting an exterior panel, and ensures jointing without performing positioning adjustment each time. An object of the present invention is to provide a mounting structure of a panel connecting portion that can be combined, and to improve workability and work quality.

[0004]

In order to achieve the above-mentioned object, the structure of the mounting structure of the panel connecting portion according to the present invention is as follows. The L-shaped plate-shaped anti-rotation Z-clip is fixed to the frame and fixed to the upper back of the lower panel in such a manner that the vertical pieces are in the vertical direction and the horizontal pieces are in the horizontal direction. A clip is attached in a posture in which a longitudinal direction is a vertical direction, a piece of the angle steel material is sandwiched between a back surface of the lower panel and a horizontal piece of the rotation preventing Z clip, and a tip piece of the Z clip is attached to the rotation preventing Z clip. The lower panel and the upper panel are connected and fixed to the angle steel by hooking on a vertical piece of the steel sheet.

[0005]

The lower panel and the upper panel are fixed to each other while being in contact with one piece of the angle steel, the dimensions of entering and exiting from the frame are constant, and joint displacement does not occur at the joint. Further, the upper panel is fixed while being placed on the upper end surface of the lower panel, and the joint width at the connecting portion is always constant.
