한옥 벽체의 시공 성능 개선방법에 관한 연구 = A Study on the Improvement of Construction Performance of Hanok Wall

다국어 초록 (Multilingual Abstract)

As with all traditional architecture in the world, Korean traditional architecture is the result of the best adaptation to the given environment. Traditional Korean architecture is most closely related to the geographical, climatic, cultural and humanities elements of the Korean Peninsula. Also, it has long been refined to meet the needs of Koreans. In particular, Hanok, a residential architecture, is closely related to people's lives. It is also recognized for its excellence in various advantages. Hanok is built with eco-friendly materials, satisfying the housing needs of many people today. Therefore, it is becoming a subject of much concern.
However, despite its excellent performance, Hanok is struggling to expand its base due to its high construction cost and insulation performance. Since the four seasons are clear in Korea, residential architecture needs to be appropriately adapted to all changing environments. Especially in summer and winter, air conditioning and heating are required. Therefore, insulation performance is necessary to prevent heat loss in buildings. Traditional Hanok structures have been pointed out as disadvantages due to insufficient insulation due to their wall composition. In addition, materials and labor costs are expensive because of the construction characteristics of the main structural parts used as wood. Other problems include embalmment, flame repellent and insect repellent. They are hampering the popularization of Hanok.
In order to solve the above problems, this study investigates the eco-friendly wall structure of Hanok that combines the eco-friendly technology with embalmment, flame repellent and insect repellent functions and modular wall with improved construction cost saving and insulation. We are trying to promote the excellence of Hanok and contribute to the promotion of Hanok.
This paper is a study on the insulation performance of Hanok walls. In addition to ensuring confidentiality, the construction convenience of lightweight components, the structural performance of wooden structures, and the mechanical performance of wall fastening have been improved. The results of the study are summarized as follows.
First, the airtight performance of the wall body has been improved. In order to ensure insulation performance, a groove is made into the column where the wall line can be inserted closely into the joint between the column and the wall line, and the method of inserting the wall line is applied. In addition, the method of minimizing drying shrinkage and integrating composition is applied by selective machining of heartwood or sapwood materials. As a result, the wall can be prevented from falling off and the deformation can be minimized.
Second, construction costs have been reduced due to material savings. Instead of using the whole log, square wood centered on the side wood is used. In addition, Pseudotsuga menziesii was used as a log tree species, which dramatically reduced material costs through high yields.
Third, the construction period can be shortened by ensuring ease of construction and installation. Through the construction of processing systems and detailed data about the main components of Hanok, large-scale production can be carried out in factories. Therefore, standardized processes and cost management systems can be established through this process to shorten the construction period and reduce the cost.
Fourth, the structural safety of the wall body was confirmed. The results of tensile strength experiment and flexural tensile strength experiment on prototype exceeded the target strength. Therefore, it was confirmed that there was no structural safety problem
As mentioned above, Hanok construction has been hampered by high construction costs and insulation performance problems. It is hoped that the results of this study will be applied to Hanok architecture to revitalize the spread of Hanok.

국문 초록 (Abstract)

본 논문은 한옥 벽체의 시공성능 개선에 관한 연구로써 기밀성 확보를 비롯하여 경량 부재의 조립화로 인한 시공의 편리성과 목구조의 최적 결구방법에 따른 구조적 성능의 개선과 벽체 결구 방식의 역학적 성능이 개선된 한옥벽체를 연구하였다. 연구의 결과를 정리하면 다음과 같다.
첫째, 벽체의 기밀성능이 향상되었다. 단열 성능의 확보를 위해 기둥과 벽선의 접합부에 벽선이 밀착되어 삽입될 수 있는 홈을 기둥에 제작하고 여기에 벽선을 끼워 넣는 제작방법을 적용하였으며, 심변재 선택 가공방식으로 건조수축의 최소화와 일체화 구성방식을 적용하여 벽체의 탈락을 방지하고 변형을 최소화 하였다.
둘째, 재료 절약에 의한 공사비가 경감되었다. 원목을 통째로 사용하는 것이 아니라 변재 위주의 각재를 사용하고 원목의 수종은 더글라스퍼를 사용함으로서 높은 수율을 통해 재료비를 획기적으로 절감할 수 있었다.
셋째, 시공 및 설치의 용이성 확보로 공사 기간의 단축이 가능하다. 한옥 주요부재에 대한 가공시스템 구축 및 시공 상세 데이터 구축을 통해 공장에서 대량생산이 가능하므로 이에 따른 표준화된 공정 및 원가관리 시스템 정착으로 공사기간의 단축과 원가가 절감된다.
넷째, 벽체의 구조적 안전성이 확인되었다. 시제품에 대한 인장강도 실험과 휨인장강도 실험을 통하여 목표 강도를 초과하는 결과를 통해 구조적 안전성에 문제가 없음을 확인하였다.
이상과 같이 그 우수성에도 불구하고 고가의 건축비 문제와 단열 성능의 문제 등이 부각되어 저변확대에 걸림돌이 되어왔던 한옥건축에 본 연구의 결과가 적용되어 한옥 보급이 활성화 되기를 기대한다.
