Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a building exterior material having superior seismic performance,

The present invention relates to a building exterior material having excellent seismic performance, and more particularly, to an exterior construction material having excellent seismic performance, which is used as an assembly panel constituting an exterior wall of a building.

The buildings are built in various structures. The building has reinforced concrete using reinforced concrete and concrete, and a steel structure that constitutes the frame of a steel frame and assembles the wall. In addition, the building is completed in various forms.

After the main skeleton and walls are completed, the building will be finished with various facilities, environment beautification and interior and exterior work.

Recently, the outer wall of a building is finished with a steel panel as a metal panel. Since the steel panel is provided in a pre-painted form, it is possible to work with a color suitable for the symbol in advance, and it has a simple and neat appearance, light weight, excellent assembling workability, and structurally robust advantages.

Conventionally, a metal panel used as a building exterior panel has a structure in which a wing portion is folded outward and spread out of a panel. Such a metal panel forms a hole in a wing portion and is configured to be coupled to an external beam by screws or bolts through holes.

Since the external force received by the external panel is transmitted to the wing portion and the center plate of the panel, the portion supporting the wing portion can be deformed or the central portion can be deformed. The member for supporting the wing portion may be distorted.

As described above, the existing metallic exterior panel for a building has a problem that the wing portion is expanded outwardly, and a wide flat plate exists on the center plate, so that the central portion of the panel is deformed or the wing portion is distorted.

As a conventional architectural panel, there is Japanese room Fair No. 6-8174. Such a Japanese utility model technique has a drawback that when the mounting metal piece, which is a bracket for mounting, is coupled to the panel, the mounting metal piece is drawn on the panel bottom face portion without being constrained, And it is disposed protruding to the lower part of the panel. Therefore, there is a problem that the packing must be closed with the bottom part of the panel by a separate packing.

Since the mounting hole of the mounting metal piece is formed in a cylindrical shape, the fastening screw of the mounting wall portion disposed through the mounting hole can be easily sheared by receiving a concentrated load directly under the head.
