Curtain Wall Remodeling System and Curtain Wall Remodeling Method Using The Same}

The present invention relates to a curtain wall remodeling system and a remodeling method for enclosing the outer walls of various buildings with glass walls, and more particularly, to be exposed to the front of a building after dismantling the glass from the inside while maintaining the curtain wall structural material already installed. The present invention relates to a curtain wall remodeling system and a method for easily remodeling a structure in which a vertical member having a thermal insulation function and a horizontal member having a heat insulating function outside the structural member is kept in a structural frame.

The curtain wall is the outer wall of the building that does not support the load of the building. It is simply a curtain that divides the space and is also called 'non-bearing partition wall'. Curtain walls function to block rain or wind from outside and to block noise and heat. The curtain wall is assembled to cross each other to form a square partition and the horizontal structural member (Transm) in the center, the vertical support portion connected to the outside of the vertical structural member to the outside of the horizontal structural member The connected horizontal support forms a grid, and includes a plurality of glass panels installed in the space partitioned in the form of the grid and also serve as external walls.

Curtain walls have the added advantage of reducing the load on the building and the beautiful appearance, and the frequency of selection of curtain walls is increasing rapidly. However, since curtain walls are mainly used for high-rise building structures, it is usually difficult to install horizontal and vertical structures in the field, it is not easy to assemble, and moreover, almost the entire surface of the outer wall is treated with a glass finish for a beautiful appearance. Therefore, the degree of insulation and airtightness is not as good as that of ordinary exterior walls.

Figure 1 is a conventional curtain wall system to vertically install vertical members between each floor vertically in each floor and combine the vertical hardware in each floor, the horizontal structural members are positioned between the vertical structural members to secure the coupling (shear block) with screws, etc. It is a structure that engages by fitting a member. However, this structure is damaged vertically because the vertical structure is vertically and the horizontal structure is located only between the vertical structure and the deterioration of the airtight material (Silicone Caulking, Gasket, etc.) between the glass and the member from the outside. In addition, there is a problem due to the deterioration of energy performance and leakage due to rainwater and inflow of wind into the space between the horizontal and vertical structural members.

Recently, due to various agreements and regulations for energy saving, the insulation performance standard of curtain wall for reducing carbon emission and energy loss has been raised and applied in Korea. Most commercial buildings, built in the 1990s, are built using curtain walls, making them the largest source of energy loss in today's buildings. The biggest obstacle to the green remodeling policy for improving the performance of the existing curtain wall is the aging due to the decrease in the rental income of the owners due to vacancy during remodeling and the increase in interior cost due to the damage of the interior finish when replacing the curtain wall. It is difficult to remodel the curtain wall building.

Recently, the insulation performance of the curtain wall system has been improved, but there is a problem in that it takes a lot of time and money to replace the curtain wall system. Republic of Korea Patent No. 1640193 relates to a curtain wall system that is easy to remodel, and disclosed a technique for a curtain wall system using a cover member that can be fitted to the vertical structural member and the horizontal structural member. However, this is not a structure for remodeling a curtain wall system that is already installed, but a limitation that the curtain wall system is easy to be remodeled at the installation stage so that remodeling may occur in the future.

Therefore, there is a need to develop a remodeling system and method for improving airtightness and insulation performance while maintaining pre-installed structural materials.
