Structural safety as well as variety and aesthetics of building facade are currently gathering more attention in building construction and stone curtain wall is widely used in exterior wall. However, two main problems are existed in curtain wall construction method. One is an uniformity of construction quality and the other is a repair work of stone panels. Also, the noise and vibration occurring in construction may be cause of civil complaint. Therefore, a new method is needed to overcome these problems. This paper presents a new stone curtain wall system using under cut anchor and secondary holes that was developed in this study. Additionally, structural performance evaluation was conducted to verify the constructability and structural safety for wind pressure and seismic load. Through the evaluation of this method, improved constructability and economic efficiency were verified.

Stone is one of the oldest and most popular materials used on the external wall because of its durability, abundance and aesthetic effect. However, there are two main problems in the existing pin hole construction method. One is uniformity of construction quality, and the other is a repair work of stone panels. Therefore, a new method is needed to overcome these problems. This paper presents a new stone curtain wall system using under cut anchor and secondary holes that was developed by authors. The improved quality and reduction of construction period can be obtained by this system.

건축을 하는데 있어 무엇보다 중요한 것은 정확한 설계, 시공 및 뛰어난 기술력이며, 각 부분 부분마다의 정확성과 뛰어난 기술이 어우러져 튼튼하고 아름다운 집이 탕생하게 되는 것이다. 이런 조건은 충족시키는 첫 번째 요소라 할 수 있는 국내 건축용 외장재 시장은 약 1조원대의 시장을 형성하고 있으며, 전체 건축비의 약 10%정도를 차지한다. 건축용 외장재 시장은 석재, 유리, 알루미늄, 아연도금철판의 기본 소재에 다양한 가공을 통하여 제품을 생산하고 있으며, 가공 및 시공의 편의성으로 인해 금속계 패널이 점진적으로 시장을 주도하고 있다. 금속계 패널은 크게 복합판넬과 sheet 패널시장으로 양분되며, sheet패널시장이 약 20%정도의 시장을 차지하고 있다. 해외의 경우, 유럽과 일본은 알루미늄계열의 패널과 미국은 철판계열의 패널이 시장을 주도하고 있다.

Recently, the enviroment problem is serious due to the global warming phenomenon because of the greenhouse gas exhaustion. In addition, the effort to reduce the problem in the situation where the severity of the destruction of environment because of the indiscriminate picking of the that is the raw material of the cement, Accordingly, in the interior of a country, the industrial site using the artificial stone instead of the natural stone is increased. Thus the cement reduction amount of use and substitute material research is the urgent actual condition with the gas emission, which here it is generated in conducting compression molding in the building stone manufacturing process performance degradation phenomenon and fire resistance, and problem of the durability. limestone and aggregate and exhaustion of resource are emphasized is continued. In this research, the fly ash and waste porcelain is applied to the magnesia phosphate composite (MPC) and the characteristic of the artificial stone according to it tries to be looked into.

Existing studies of building exterior materials have focused on the colors or textures of cladding, and in terms of a design planning approach, have focused on the use of the environment and equipment and fire safety topics from an engineering perspective. As a result, little research has been done on performance guidelines for exterior materials, specifically according to the building type. Research into eco-friendly cladding materials is also in the rudimentary stage in a practical sense. In this study, the use of exterior materials over the last ten years in domestic construction was analyzed. The usage status of building exterior materials was evaluated quantitatively by frequency analysis, and its environmental performance is proposed through complex (qualitative + quantitative) analysis. The average value of the exterior material type number used for all analyzed buildings was 2.59. Glass, metal, stone, resin, cement, wood, and clay were used in that order with regard to the usage status. The analysis found that five of the materials satisfied the high efficiency and eco-friendly grading in terms of the four characteristics of an eco-friendly exterior. A list of eight eco-friendly elements was also proposed. The eco-friendly elements and characteristics of the exterior materials were derived to provide basic guidelines for domestic construction companies and design offices.

In recently constructed building, It has become fashionable again that the heavy external skin system such as a Stone Finished Envelope. There are Squared Steel Pipe Methods, C-Shaped Steel Pipe Methods, and Aluminum Beam Methods in the structure of a heavy external skin system. The Aluminum Beam Methods is often misunderstood as a Plane Truss Structure, but this method is not appropriate to be called to a truss structure but a beam methods. The Aluminum Beam Methods is the most Eco-friendly methods in terms of Quality assurance, Efficiency, Safety, Construction period, Durability, and Recyclability. And this Methods is also very appropriate in considering the point of Energy conservation, Waste reduction, Long-life architecture, Replacement parts, Environmental protection, Public efficiency, and Building demolition.

Steel method compared with conventional aluminum truss construction materials as the biggest difference, aluminum truss method by using an aluminum material construction of the existing steel truss compared with the welding operation is omitted, as the air operations will be reduced by about 40% do not need skilled workers in the existing portion of each tube and cost 11,233 to 13,173 won/㎡ cheap it was found.

본 연구에서는 건축외장용 접착제의 발연특성을 알아보기 위해 접착제를 용도별로 구분하여 연기밀도시험기를 이용해 최대연기밀도와 초기발생연기밀도를 알아보았다. 실험 결과 창호전용 접착제가 586초에 509.64로 가장 많은 연기밀도를 발생하였으며, 석재용 275.63, 목공용 232.25의 순으로 많은 양의 연기가 발생하였고, 타일용 18.65, 스티로폼용 6.44로 최대연기밀도를 나타내었다. 창호전용과 스티로폼용의 경우 최대연기밀도를 나타낸 시간은 비슷한 범위에 나타났으나 연기밀도 값은 스티로폼용에 비해 창호전용 접착제가 80배 가까이 연기가 더 발생하는 것을 알 수 있었다.
