Description

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 on an outer wall surface of a skeleton, and more particularly to a structure for mounting a connecting portion between an upper panel lower portion and a lower panel upper portion.

[0002]

2. Description of the Related Art Exterior plates are attached to the outer wall surface of a building by various methods. For example, in the case of attaching a large-sized exterior plate, a high supporting force is required due to its weight, and therefore a dry method that can structurally support the exterior plate is adopted.
In the dry method, metal fittings with a positioning adjustment function that can adjust the entrance / exit dimension from the outer wall surface of the body and the height dimension of the left and right sides of the panel are generally used. For example, when this metal fitting is composed of a fixing metal fitting and a mounting metal fitting, the mounting metal fitting is embedded in the exterior plate, while the fixing metal fitting is welded and fixed to the support frame fixed to the body side. Then, the fixing metal plate and the mounting metal plate are adjusted and engaged with each other so that the entrance / exit size from the frame and the joints of the exterior plates are matched, and the exterior plate is attached to a predetermined position on the outer wall surface of the frame.

[0003]

However, it is very difficult to attach the exterior plate in the above-mentioned dry method in which the fixing metal fitting is engaged with the fixing metal fitting. That is, the exterior plate is generally carried by a crane to the attachment position on the outer wall surface of the body, and is sequentially attached upward from the lower part of the outer wall, but it is fixed while matching the entrance and exit dimensions and joints of the adjacent exterior plates vertically. Engaging the metal fittings and the fittings was a lot of effort and time. Further, fixing the fixing metal fittings to the support frame by welding is extremely inconvenient because it requires a lot of work in high places. Furthermore, if the mounting bracket is embedded in the exterior plate, the exterior plate structure becomes complicated and the number of manufacturing steps is increased. The present invention has been made in view of the above circumstances, and it is not necessary to embed metal fittings in the exterior panel, welding metal fittings when mounting the exterior plate is unnecessary, and moreover, it is possible to reliably perform joint adjustment without performing positioning adjustment each time. The purpose of the invention is to provide a panel connecting part mounting structure that can be matched and improve workability and work quality.

[0004]

In order to achieve the above object, the structure of the panel connecting portion mounting structure according to the present invention has a structure in which a mountain-shaped steel material is arranged in a vertical direction with one piece being parallel to the outer wall surface of the body. It is fixed to the body, and an L-shaped plate anti-rotation Z clip is fixed to the upper back surface of the lower panel with the vertical piece in the vertical direction and the horizontal piece in the horizontal direction. The clip is attached in a posture in which the longitudinal direction is the vertical direction, one piece of the angle steel material is sandwiched between the back surface of the lower panel and the horizontal piece of the rotation preventing Z clip, and the tip piece of the Z clip is attached to the rotation preventing Z clip. It is characterized in that the lower panel and the upper panel are connected and fixed to the chevron steel material by being hooked on the vertical piece.

[0005]

The lower panel and the upper panel are both fixed in contact with one piece of the chevron steel material so that the size of entry and exit from the skeleton is constant, and no joint misalignment occurs at the connecting portion. Further, the upper panel is fixed in a state of being placed on the upper end surface of the lower panel, and the joint width at the connecting portion is always constant.
