Description

Curtain Wall Structure with Improved Insulation and Structural Performance}

The present invention relates to a curtain wall structure with improved insulation and structural performance, and more particularly, a thin plate-shaped insulating plate provided between a pair of flange portions protruding forward of the main profile, and insulating an aluminum reinforcing bar formed in a grid-shaped cross-section. The present invention relates to a curtain wall structure having improved heat insulation and structural performance formed to stably support a glass panel by providing in close contact with the plate in contact with the front and having a middle supporter in front of the aluminum reinforcing bar.

In general, windows are installed on the walls of buildings in contact with the outside air for the purpose of viewing, sunlight, and ventilation, and in recent years, there is a trend of using pair glass with air layers mostly for the purpose of energy saving through securing insulation performance. .

On the other hand, recently, curtain wall structures have been widely applied for the aesthetics of the building's elevation and the efficiency of construction. In general, a frame by combining a vertical member (Mullion) and a horizontal member (Transom) through a bracket to the strength structure of a building. And the curtain wall structure is constructed by bonding the finishing panel to the frame. In particular, in the case of applying a double-layered glass as a finishing panel, there is an advantage of giving a modern feel to the exterior of a building by breaking away from the concept of traditional windows, and enabling efficient use of energy by using natural light.

In such a curtain wall structure, a support member is typically coupled to be exposed to the outside of the frame, and the support member is coupled and fixed in a state where the side surface of the multilayer glass is mounted on the support member. At this time, in fixing the support member and the multilayer glass to each other, the sealant was used as a medium, or a cap member was additionally provided to the sealant to be press-coupled with bolts. However, in the conventional coupling structure of a curtain wall, two conflicting limitations were caused in coupling and fixing by providing a support member between a plurality of multilayer glasses disposed adjacent to each other.

Specifically, aluminum is used as the material of the frame, which can secure weight reduction and structural performance at the same time, but this caused a heat bridge phenomenon in which indoor warmth escapes or outdoor cold air easily enters due to the high thermal conductivity of aluminum. Therefore, the support member inevitably must be provided with a synthetic resin insulation material such as polyamide or azone in order to secure the insulation performance, but this is a limitation of lowering structural stability in supporting the self-weight of the multilayer glass itself or the wind load due to the nature of the synthetic resin material. There was.

On the other hand, when the main material of the support member is made of a metal material such as aluminum in consideration of structural stability, the structural strength is secured, but there is a problem in that the thermal insulation performance is rapidly deteriorated due to the characteristics of the metal material having high thermal conductivity.

Accordingly, recently, there are a number of prior art documents that have been proposed to secure structural stability by partially adding a metal material while trying to achieve thermal insulation performance by using polyamide or azone as an insulating material by fabricating a support member in a composite structure.

As a related prior art document, there is Korean Patent Registration No. 1780483 "High Insulation Curtain Wall System" (registered on September 15, 2017, hereinafter referred to as "prior art document").

However, the prior art document supports the self-weight and lateral load of the glass on the basis of the glass support member 5, not the metal support member 4, inevitably the metal setting chair 6 on the top of the glass support member 5 There was a limit to be partially additionally equipped. However, the metal setting chair 6 is provided discontinuously at 1/4 of the load, but it is provided to be directly exposed to the outside air, thus still causing a thermal bridge phenomenon, and the metal support member 4 and the metal setting chair In bonding (6) to each other, since the piece fastening is essential, there is an additional limitation in that heat conduction is caused by the fastening means.

In addition, in terms of structure, the material of the glass support member 5 was still made of synthetic resin, so it was structurally weak. In particular, the polyamide insulation material 3 in the section bonded to glass was used to adhere to the glass. When applying the sealant, due to the characteristics of the material, sufficient adhesion performance was not secured, so there was a limit that it could be applied only to a cap-type that has a cap fastened with a piece and pressurized.
