Description

Curtain Wall{CURTAIN WALL}

The present invention relates to a curtain wall, and more particularly, to a curtain wall having improved thermal insulation and work efficiency.

In general, the curtain wall method is a method in which the load acting on the building in a structure made of reinforced concrete or steel frame is supported only by the frame made of columns, beams, and slabs, and the external wall is formed as a non-bearing wall that does not bear the load say This curtain wall construction method can lighten the exterior wall, can mass-produce it in a factory by standardization, and can be carried out in parallel with the frame construction, so it is not only economical, but also has a beautiful appearance, so it is widely used in high-rise buildings. have. Curtain walls are divided into mullion type, spandrel type, grid type, etc. depending on the exterior shape. In particular, the grid type can show vertical and horizontal grid-type exteriors. It is often used for curtain walls.

Typically, the curtain wall is configured to connect a plurality of double-glazed glasses by mounting a frame on two adjacent double-glazed glasses that are vertically erected to be spaced apart from each other. In this case, the frame applied to the conventional curtain wall is generally made of aluminum to improve adhesion with the multi-layer glass, but since aluminum has weak rigidity, the thickness and size of the frame must be increased. If the thickness and size of the frame made of aluminum are increased in this way, the frame manufacturing cost is very high, and there is a disadvantage that the curtain wall construction cost is increased. Of course, if the frame as a whole is made of steel, the rigidity of the frame increases, but the steel material has a small strain rate and a very low impact absorption rate, so there is a problem that not only the adhesion with the laminated glass is deteriorated, but there is a problem that the laminated glass may be damaged.

On the other hand, since the main purpose of the curtain wall is to protect the interior space of the building from rain and wind, wind pressure, joint watertightness, airtightness, and heat insulation are important functional factors. That is, the curtain wall should provide a comfortable indoor environment by protecting the inside of the building from wind or rainwater. Such a curtain wall may be fixed to the skeleton of a building by a curtain wall frame. For example, in high-rise construction, the curtain wall frame may be coupled to the skeleton of the building by means of fasteners. Glass can be bonded to this curtain wall frame.
