Description

Corner cap for metal panels for interior and exterior finishing {Corner Cap For Metal Panel}

The present invention relates to an edge finishing material, and more specifically, to a material for finishing the open square edges of metal panels for interior and exterior finishing that are bent and molded to obtain a waterproof function, a function of continuously maintaining its original shape, and a safety function during handling. , relates to edge finishing materials for metal panels for exterior finishing.

In general, dry finishing method (DRY WALL FIXING), which fixes and installs metal panels for finishing on the interior, exterior walls, or ceiling of a building, involves fixing installation members including clamps to the interior, exterior walls, or ceiling of the building, and then attaching the installation members. It is constructed by installing a metal panel as a medium. This dry finishing method is currently widely used due to its short construction time, convenience of work, and construction advantages.

Here, metal panels used for interior and exterior finishing of buildings generally have a structure that includes a front plate in the form of a square plate and bending pieces that are vertically bent around the outer circumference of the front plate. Such metal panels for interior and exterior finishing are made by removing the corners of the fabric in the form of a square flat plate and forming bent pieces on each side (four sides) of the front plate when bending and forming the bent pieces. It is formed by bending it at a 90-degree angle.

Figure 1 is a perspective view showing a representative example of a conventional metal panel for interior and exterior finishing, and Figure 2 is a perspective view of a main part to explain the gap formed at the corner of a conventional metal panel for interior and exterior finishing.

Referring to FIG. 1, the conventional metal panel 100 is vertically bent and formed with bent pieces 120 around the outer circumference of a square plate-shaped front plate 110. At this time, a gap 130 is inevitably generated between the bent piece 120 located at the edge of the metal panel 100 and the bent piece 120. In other words, in the conventional metal panel 100, the bent piece 120 that is formed by bending and both ends of the bent piece 120 do not contact each other, and a gap portion 130 corresponding to the thickness of the original metal panel is generated. This gap 130 is formed in the form of a straight through hole between the bent piece 120 and both ends of the bent piece 120, and is formed to be narrow in width at the portion in contact with the front plate 110.

When constructing a metal panel as an exterior panel, the above-mentioned gap has the problem of becoming an inflow passage for rainwater or dust. Rainwater or dust introduced in this way acts as a factor in corroding or contaminating the inner surface of the metal panel. . In addition, the above-described gap has a problem in that over a long period of time, the gap gradually widens or contracts irregularly due to external force, such as wind, which acts as a factor of separation from the installation member. In addition, the above-mentioned gap acts as a factor that deteriorates the appearance of the metal panel, and at the same time, the end of the bent piece where the gap is formed is sharp, so when workers handle the metal panel, there is safety risk, such as damage to the body from the sharp edge. Accidents may occur.

Accordingly, in Republic of Korea Patent No. 10-2172930 (announced on November 2, 2020), a coupling means is applied to the bent piece (side plate) to solve the problems of deformation and oxidation that occur in the conventional method of welding the gap area of the metal panel. A 'joint area reinforced metal panel for construction' is disclosed, which includes a reinforcing plate for reinforcing the corner area, that is, the joint area where the bent pieces (side plates) are integrally joined by the coupling means.

However, the above-mentioned Korean Patent No. 10-2172930 has a complicated structure because the reinforcing plate and the coupling means must be extended from the bent piece (side plate), and the process of bending the reinforcing plate from the bent piece (side plate) There is a problem that manufacturing is difficult because the process of riveting the reinforcement plate and the bent piece (side plate) and pressurizing the coupling means with a forming roller so that they engage with each other must be performed.

Referring to FIG. 4, the external contact bar 2 constituting the edge finishing material 1 is installed in contact with the end surfaces 521 of the facing bent pieces 52 at the edge. It is preferable that the external contact bar 2 has a fan-shaped cross-sectional structure so as to firmly contact the end surfaces 521 of the bent pieces 52. In addition, one end of the external contact bar 2, that is, one end installed at the bent portion of the bent pieces 52, is provided with a streamlined protrusion 21. At this time, the streamlined protrusion 21 is preferably given a structure corresponding to the shape of the bent portion of the bent pieces 52, that is, a structure that becomes sharper toward the end, as shown in FIG. 5.

The inner contact bar 3 is installed to contact the inner surfaces 522 of the facing bent pieces 52 at the corners.
