The present invention relates to an envelope system of a building and a method of constructing the envelope system. More particularly, the present invention relates to an envelope system of a building, A curtain wall exterior system capable of effectively reducing the weight of the construction material and improving the workability by means of an improved construction structure to form a non-proof wall in the form of a curtain wall, .

Recently, large-scale new buildings such as commercial buildings and residential complexes are becoming more and more super-tall, large-scale, and complex, and they are becoming a landmark of the area.

Generally, in the case of a super high-rise large-scale composite structure, it is not only necessary to reduce the weight of the envelope system for structural stability and self-weight reduction due to the increase in its own weight, but also interest in various and beautiful appearance is gradually increasing.

Accordingly, in recent years, the envelope system of a building, which is constructed to be enlarged and combined with a super high-rise building, is a curtain wall exterior system that is effective in pursuit of aesthetic appearance through structural safety, construction method and diversity of material selection Construction work is increasing.

As is well known, a curtain wall exterior system is a construction method for constructing an outer wall structure by forming a non bearing wall excluding a framed wall on an outer wall of a building composed only of columns and beams. A truss frame, also referred to as a back frame, is installed in the building slab and relatively lightweight exterior panels such as glass, wood, stone and aluminum are installed on the truss frame as a curtain wall- .

Meanwhile, in a conventional truss frame used as a back frame in a construction process for constructing the above-described curtain wall sheathing system, a steel frame called "C-shaped steel or -shaped steel" a vertical member made of steel pipes and a horizontal member are formed in the shape of a rectangular frame so as to form a framework of a grid structure by welding.

Therefore, in the case of a conventional lattice type truss frame for installing a curtain wall external system, since relatively heavy steel is used as a material, it causes a problem of weight increase and it is difficult to reduce the weight, There is a problem that construction constraints are imposed according to the design structure of the building.

In addition, the conventional grid-type truss frame is a cost-effective and time-consuming method for cutting and welding the vertical member and the horizontal member, In addition, there is a problem that the stress in the welded portion generates local warpage or the like, which lowers the rigidity and the precision of the construction, thereby deteriorating the structural stability.

In addition, since the conventional lattice truss frame requires a large amount of necessary parts such as anchor for an external panel and a bracket and a fastening member such as a bracket, the construction cost, the construction time, There are disadvantages and problems that efficiency and economy are inferior.

SUMMARY OF THE INVENTION The present invention has been made in view of the technical background as described above and it is an object of the present invention to solve the problems of the background art described above, It can not be said to have been publicly known to the general public before.
