Description

  The present invention relates to a decorative frame provided in an opening of a building.

  Windows are provided on the outer wall of the building for lighting and ventilation. Thus, a decorative frame is provided in the opening of the outer wall where the window is formed in order to improve the aesthetic appearance. The decorative frame is composed of a plurality of decorative frame members, and each decorative frame member is framed in a square frame shape and fixed to the opening.

  As a typical prior art of a decorative frame, for example, Patent Document 1 can be cited. FIG. 9 is a diagram illustrating a decorative frame according to the related art. In this prior art, a long frame member 100 provided with protruding tapping holes 101a and 101b extending in the longitudinal direction on one surface is prepared, and the frame member 100 is adjusted to the size of the opening during construction.

  However, in the prior art, since each end adjacent to each frame member in the circumferential direction is directly butted and screwed, when each frame member is framed in a square frame shape, the circumferential direction of each frame member is There is a problem that it is difficult to accurately and stably position adjacent end portions at appropriate positions, and workability of the frame work of the decorative frame is poor.

  In addition, each frame material constituting the decorative frame is made from about 1 m to about 2 m long material obtained by extruding synthetic resin from a viewpoint of productivity and ease of processing to a standard length of about 0.5 m to about 2 m. Manufactured as a cut short material. Therefore, although each panel is within a tolerance range, the surface may have wavy distortion due to thermal shrinkage accompanying a temperature decrease after extrusion, and the flatness is low.

  Furthermore, the size of the opening on the outer wall to which the decorative frame is attached varies depending on the structure of the building and the attachment position, and is not uniform. Therefore, the frame members are often used by being manually cut according to the size of the opening at the installation site. The panel is cut at such an installation site by an operator manually marking a cutting position on each panel and manually using a cutting tool such as a saw. The cutting surface of each panel cut using a cutting tool such as a saw may cause inclination or unevenness in the longitudinal direction, width direction, and thickness direction of each panel, even if it is a skilled worker. A flat cut surface cannot be formed.

  Using the panel cut in this way, the end surface of the other panel is brought into contact with the surface of one panel, and each panel is positioned vertically. A gap due to the inclination and unevenness of the cut surface is generated between the cut surface. In this state, when the end portions adjacent to each other in the circumferential direction of each panel are fixed with bolts, the portion with the large gap is fixed in close proximity by tightening the bolt, but on the other hand, it is perpendicular to the panel surface. The part of the cut surface of the other panel that has been in contact without causing a gap in the panel is separated from the panel surface of the one panel, thereby creating a new gap and the watertightness of the decorative frame. In addition, there is a problem that the strength is lowered.
