Description

  The present invention relates to a curtain wall that forms the exterior of a high-rise building, and specifically relates to a curtain wall unit having a double structure of an inner window portion and an outer window portion, and more specifically, to an inner side. The present invention relates to a curtain wall in which a window provided in a window portion is directly attached to a horizontal frame or a vertical frame without a window frame.

  In general, the main structure that bears the load of a building consists only of a frame composed of columns and beams, and this frame supports the vertical load applied to the building and the horizontal load caused by the wind. Since the wall of the building simply serves to partition the space, such a wall is called a “curtain wall” or “non-bearing partition wall”. Curtain walls prevent rain and wind from outside, block noise and heat, prevent columns and beams from being exposed to the outside, and perform important functions for exterior use in modern architectural styles. In particular, it is often used in high-rise buildings and skyscrapers.

  Looking at the construction process of the curtain wall, after transporting a fixed-size outer wall panel manufactured in the factory (hereinafter referred to as the “curtain wall unit”) to the construction site, it is applied to the outer wall of the building using mechanical means. Many methods are used to lift and place them around the building vertically and horizontally, and connect them together. In this way, curtain wall units are standardized and manufactured in large quantities at the factory, so there is unity and the appearance of the building can be made beautiful.

  The curtain wall unit has a vertical vertical frame made of an extruded aluminum material and a horizontal horizontal frame made of the extruded aluminum material, and a glass window between the vertical frame and the horizontal frame. Is manufactured in the factory according to the process of installation. At the construction site, such curtain wall units are assembled together to form the outer wall of the building.
