Description

[Detailed description of the invention] (a) Technical field The present invention relates to an architectural picture frame and a corner joint of the picture frame.

(B) Background technology Conventionally, as a method for treating the edges of interior and exterior wall materials such as around windows, the wall materials were cut and then attached to a piece of sash, etc., or a picture frame was made of wood.

However, processing wood into picture frames and painting it after installation is time-consuming and expensive. In addition, over many years, the color and wood will rot and the appearance will become very poor.

There are also extrusion-molded parts with notches at the ends that fit together, but this creates gaps at the joint surfaces on the back surface that contact the inner and outer walls of the frame material, impairing the aesthetics and also creating a risk of rainwater infiltrating. There was a flaw.

(c) Purpose of the invention The present invention solves the above-mentioned conventional drawbacks and provides a picture frame that is weather resistant, has a good appearance, and is inexpensive.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

(d) Structure of the invention Figure 1 is a cross-sectional view showing an embodiment of the picture frame according to the invention. It can be formed by forming from a thin metal plate, is suitable for mass production, and the horizontal part 3 allows for easy access to the interior. Prevents water from entering.

In Figure 2, 45-degree V-cuts are made for corners 1, 4, 5, and 6, leaving a vertical part 2 in the middle of the frame, and a notch is made in the horizontal part 3 to attach the external material. When using, bend the vertical part of 2 at 90 degrees. After construction is completed, it will look like Figure 3.

(e) Effects of the invention As detailed above, the architectural picture frame according to the invention has a long vertical part on the back, so it is not only easy to join, but also has a right angle in the longitudinal direction.
Corner joints are made using a 45 degree V-shaped notch.
Since the cut surface on one side is joined to the flat surface on the other side, it is difficult to form a gap at the joint, and even an inexperienced worker can obtain a clean joint.

Originally, fixing the corners of a picture frame was considered to be a relatively advanced technique, but according to the present invention, it is possible to provide a fixing process for the corners of a picture frame at a low cost, and it is also resistant to rainwater penetration and has an excellent aesthetic appearance. It becomes certain.
