TECHNICAL FIELD OF THE INVENTION
The present invention relates to a metal panel type curtain wall capable of easily correcting surface distortion of a metal panel stretched on the surface.
[0002]
[Prior art]
2. Description of the Related Art In recent years, in the construction work of a building or the like, a curtain wall construction method in which a curtain wall manufactured in a factory in advance is sequentially built on an outer wall has become mainstream. As the curtain wall, not only a glass-fitting type, but also a metal panel such as an aluminum panel as a surface plate, a stone plate, a tile, a ceramic plate, etc. are arranged to meet various design requirements. Are provided.
[0003]
When an aluminum panel is used for a curtain wall among these curtain walls, a structure is generally adopted in which a frame is formed of a rectangular steel material or the like, and the aluminum panel is stretched on the surface side thereof.
[0004]
[Problems to be solved by the invention]
However, since the aluminum panel uses a thin plate of several mm, the aluminum panel has a small sectional rigidity and high deformability. Therefore, when the frame is stretched over the frame, the surface does not become a perfect plane, but a slight but convex surface and a concave surface are mixed, and the entire outer surface appears distorted by the reflected image. This tendency tends to be remarkable in proportion to the increase in the size of the aluminum panel.
[0005]
In order to correct such surface distortion of the aluminum panel, a gentle curve is conventionally provided at the time of installation so as to have a convex surface on the outdoor side. Specifically, as shown in FIG. 11, on an intermediate vertical frame 51 provided inside the frame frame 50, a reinforcing material 53 is provided on the back surface of the aluminum panel 52 along the horizontal direction at intervals in the vertical direction. Are provided, and connecting members 54, 54... Having one ends connected to the reinforcing member 53 are provided, and fixing screws are passed through long holes 54a (fixing loose holes) formed in these connecting members 54 to fix the intermediate member. At the time of screwing to the vertical frame 51, by adjusting the position of the connecting member 54 in the indoor and outdoor directions, the aluminum panel 52 is given a curved shape that becomes convex on the outdoor side.
[0006]
However, in the case of adjustment using the fixing loose hole, if the fixing screw is loosened, the connecting member is opened, so that fine adjustment is difficult, and the entire aluminum panel can be formed into a convex curved surface protruding to the outside of the room. However, since the aluminum panel cannot be accurately curved along a single curved surface and becomes a composite curved surface, it has been difficult to completely eliminate surface distortion. In addition, the work requires a lot of labor because it is difficult to fine-tune the work.
[0007]
Therefore, a main object of the present invention is to provide a curtain wall having a metal panel on the surface side, in which the surface distortion of the metal panel can be corrected easily and labor-saving, and the entire surface can have a gentle and uniform convex shape. An object of the present invention is to provide a curtain wall.
[0008]
[Means for Solving the Problems]
As a first aspect of the present invention to solve the above-mentioned problem, in a curtain wall in which a metal panel is stretched on one surface side of a face material made of a frame material,

[0009]
In the invention according to the first aspect of the present invention, since the distortion correcting connection metal fitting having the function of adjusting the entrance and exit in the indoor and outdoor directions is provided and the position of the metal panel in the indoor and outdoor directions can be adjusted arbitrarily, the curved shape of the entire panel is simple It can be adjusted easily and labor-saving so as to form a curved surface, and surface distortion can be corrected inconspicuously. In addition, since the metal panel is supported on the back side, the large-sized metal plate can be prevented from being swung (deformation in the indoor and outdoor directions), and a stable panel state can be maintained after adjustment.
[0010]
According to a second aspect of the present invention, the distortion correcting connection bracket is connected to a fixing bracket fixed to a frame member by a bolt / connection shaft and a nut, and one end of the connection member is connected to the reinforcing member. 2. A metal panel type curtain wall capable of correcting surface distortion according to claim 1, wherein said metal panel type curtain wall is combined with a position adjusting bracket capable of adjusting the position in the indoor and outdoor directions by retreating said nut. As the structure of the distortion correcting connection fitting, various structures can be adopted as long as it has a function of adjusting the entrance and exit in the indoor and outdoor directions, and a structure including the fixing fitting and the position adjusting fitting can be suitably adopted. . Since the position adjustment is performed by retreating the nut, fine adjustment can be easily performed.
[0011]
According to a third aspect of the present invention, in the surface distortion according to any one of the first and second aspects, the position adjustment fitting has a loose hole for fixing in the indoor and outdoor directions, and can be screw-fixed to the frame member after adjustment. And a metal panel type curtain wall capable of correcting the above. After the adjustment, it is desirable that the position adjustment fitting is firmly fixed to the frame member by screwing so that the position does not change thereafter.
[0012]
According to a fourth aspect of the present invention, one end of the distortion correction connection fitting is connected to a reinforcing member via a cushioning material, and the surface distortion according to any one of the first to third aspects is corrected. A metal panel curtain wall is provided. By interposing the cushioning material, it is possible to eliminate noise caused by contact between metals during position adjustment.
[0013]
As the present invention according to claim 5, the face material has at least an intermediate vertical frame inside a frame frame, and one or a plurality of the distortion correcting connection metal fittings are arranged along the vertical direction with respect to the intermediate vertical frame. A metal panel-type curtain wall capable of correcting surface distortion according to any one of claims 1 to 4 is provided. It is desirable that the straightening fitting is disposed at an intermediate position, preferably a central position, of the metal panel, and is desirably provided at a plurality of positions along a vertical center line.
[0014]
