최근들어 심화되고있는 자재난과 인력수급난등은 작업을 원활치 못하게 하는 요인으로 작용하여 공기를 지연 시키고 있어 건설업계가 호황속에 불황을 맞고 있는 실정이다. 이에 따라 건설업계 스스로 자구책을 강구해야 한다는 여론이 높아지고 있어 신자재 개발 및 신공법 개발을 더욱더 서두르고 있다. 몇몇 건설업체들은 이미 자동화 공정 미 건식공법 등을 도입 실용 단계에 들어갔으며 시험단계 중인 업체들도 상당수를 차지해 조만간 걸설업계에도 신공화법의 바람이 불 것으로 관련인들은 내다보고 있다. (주)한양 기계부는 그동안 화장실 벽체 배관의 공장 조립 시공화 방안을 연구 검토한 결과 그 타당성이 인정되어 올해 초부터 이 방안을 본격적으로 시공에 착수했다. 이에 본지는 신공법 개발의 한 분야로 이 방안을 소개 한다.

Recently, polishing tile(porcelain homogeneous polished tile) was used in the construction field as a finishing material. But, there happened some problems such as tile exfoliation by construction condition in early ages. Also, for use of polishing tile in the dry wall system which used to lightweight wall, the examination of adhesive stability of polishing tile is needed. In this study, adhesive strength of Polishing tile was investigated by tile bond types on gypsum board and non asbestos board coated by tar-urethane and Polymer modified cementitious waterproofing membrane(Series I). Then, the effect of heat stress and vibration was estimated on gypsum and non asbestos board(Series II). As the result of study are the follows; (1) Polishing tile(600$\times$400mm) construction on waterproofing layer : Both laboratory estimation and spot examination sieve were happened that fall of tile because their hardening speed is late. (2) To using powder style adhesives in the dry wail with waterproofing layer : Adhesive strength of tile is Influenced by interface bond area and base side condition. (3) Shock and heat stresses : obvious decline of adhesive strength is not happened

Due to the nature of the existing load, the criteria of assessing the intensity of the lightweight wall's impact resistance has been though of as obscure. The current study, therefore, focuses on the standardized assessment of the impact resistance to the force of the large soft body applying to the lightweight wall. The gypsum board wall showed a low level of the maximum residual displacement. It is, however, required to be careful about the selection of the finishing process since the high level of the maximum displacement is likely to cause harm to finishing materials. Unlike the gypsum board, the ALC block wall displayed a considerable rigidity while showing almost no maximum residual displacement. Even with the low level of the maximum displacement due to the stiffness, the ALC block wall is still likely to be affected by the vibration derived from any impact on the surface, which demands a need for additional study. The future experimental study, accordingly, will focus on the impact of the vibration on finishing materials, consequently leading to the accurate prediction of the possibility of potential damage to the lightweight wall caused by the large soft body.

이노가닉 폴리머 콘크리트는 비소성 알카리 활성화 콘크리트의 일종으로 여러 가지 우수한 성능을 가지고 있으며, 그 중에서도 고온에서의 열적특성이 우수한 것으로 알려져 있다. 이에 따라, 이노가닉 폴리머 콘크리트를 이용한 경량패널을 제조하여, 소형가열로 내화시험을 측정한 결과 3시간 가열후 이면상승온도가 평균 82℃ 이하로 확인되어 공동주택의 내화벽체로 활용이 가능할 것으로 판단된다.

The purpose of this study is to obtain basic data for making performance criteria about the structural safety of lightweight dry wall later by examining types and characteristics of horizontal load acting on the wall. The subjects applying horizontal load to the wall are human and objects. The types of horizontal load are classified as static load and dynamic load depending on the difference of acting time. The magnitude of horizontal load "0.25kN/㎡" defined by KBC 2009 has no significant meaning since it is the unsubstantial nominal load. The result of examining types and characteristics of horizontal load is as follows. (1) Static load by human needs to have more systematic investigation including differences in wall hardness and human weight. (2) Dynamic load by human needs to raise the significance of study result by increasing the number of subjects. (3) Dynamic load by objects needs to accumulate the load specific data for various load subjects considering real situations.

모듈러 건축물을 중고층화하기 위해 횡력저항시스템은 반드시 필요한 구조 요소로 10~20층 규모에서 콘크리트 코어는 가장 전형적인 횡력저항시스템으로 알려져 있다. 습식 공법인 콘크리트 코어 공사는 모듈의 오염과 파손 가능성으로 모듈 적층과의 동시 작업이 곤란하다. 이에 모듈 적층과 콘크리트 코어의 동시 시공이 가능한 복합 PC 패널 공법을 개발하였다. 복합 PC 패널은 일정 간격을 두고 웨브가 마주보는 한 쌍의 C형강을 콘크리트 벽체의 상부와 하부에 결합한 구조 부재로 볼트로 접합하여 적층하는 건식 공법으로 콘크리트 코어를 구축할 수 있다. 이 연구에서는 복합 PC 패널이 콘크리트 벽체와 동등한 성능을 갖도록 해석을 통해 상세 개선 과정을 제시하였다.

Among common test methods of assessing structure safety for existing lightweight walls, the criteria of the quality assessment of the horizontal static load resistance has been considered ambiguous. In the current study, therefore, an experiment was conducted to figure out the standardized assessment criteria of the lightweight wall's horizontal static load resistance. Based on the findings of the experiment with gypsum board and ALC block walls, an acceptable amount of each standard and the variables of the stud wall arising from the appropriate load (1000N) on the wall in a daily life were accounted for, arbitrarily setting the maximum deformation amount below 15mm.

Recently, the structural system of public residential buildings has been changed from the reinforced concrete (RC) wall system to the (PC) wall and moment resisting systems. Thus, it is important to develop the suitable wall system in accordance with the trend of the modern structural system. This paper presents the basic study on the suitable boundary wall in high-rise buildings. The research also demonstrates the evaluation results on sound characteristics in the aspect of sound insulation. The evaluation of sound insulation capability for the commercialized wall structure was conducted based on literature survey while the measurement of sound insulation capability for the light-weght EPP concrete was performed in according to KS F2808 in laboratory. The main objective of this research is to propose the most suitable dry wall system as a sound insulation structure through the comparison and analysis of frequency characteristics and weight-acoustic attenuation.

Breaking the rigid connection between the two faces of the wall can significantly improve the sound transmission loss of the wall. This is usually achieved by resiliently mounting the gypsum board on one of the two faces of the wall using resilient channel. Resilient channel with less stiffness than that of air cavity could move the resonance frequency of the light-weight wall. So we can get higher sound transmission loss at low frequencies for light-weight wall using resilient channel. It's sound transmission loss is 17 dB higher than that of single stud wall, and 5 dB higher than that of double stud wall.
