Modular house is built by assembling various joints. Module assembly in the stage of on-site installation is very important process, because assembly process directly affects the structural stability and the quality. However, manual tools and electric-powered tools have a problem in that assembly productivity and quality are reduced during long-time usage. Although pneumatic assembly tools for modular house have been developed, but empirical analysis to compare and evaluate the performance of tools has not been sufficient. This study compares and analyzes the assembly quality and productivity by applying existing assembly tools and new pneumatic tools to the field. The analysis results show that pneumatic assembly tools are more excellent in terms of assembly productivity and quality.

Estimating the construction period at the initial stage of the project and determining whether it is appropriate is very important for the developer's decision-making and the success of the construction company's business. Existing researchers have conducted various studies to calculate the appropriate construction period, but there is no study on the influencing factors and methodology for the construction period of beam-column PC apartment building frame construction. The purpose of this study is to calculate the PC member assembly time using the mathematical algorithm of PC member assembly. The results of this study can be used as basic data to calculate the construction date of the standard floor of PC construction.

최근(最近) 우리나라에서는 목재외(木材外)의 타계재료(他界材料)로의 건축(建築)이 이루어지고 있으므로 목조건축(木造建築)에 관한 연구(硏究)와 관심(關心)이 급속(急速)히 감소(減少)하고 있다. 이것은 국내(國內)에서의 목재생산(木材生産)이 극(極)히 저조(低調)하고 가격(價格)의 폭등(暴騰)으로 나타난 필연적(必然的)인 현상(現象)이라 하겠으나 목조건축(木造建築)이 아닌 타계재료(他界材料)로 시공(施工)한다고 하여도 목재(木材)는 꼭 쓰여지기 마련이다. 그러므로 주택(住宅)을 중심(中心)으로 각종건축물(各種建築物)의 구조(構造)를 이해(理解)함으로써 보다 합리적(合理的)인 목재이용(木材利用)을 꾀할 수 있을 것이다. 특히 목조주택(木造住宅)에 의존(依存)하고 있는 미국(美國)에서 경구조(輕構造)(light frame house construction) 또는 조립주택(組立住宅)(prefabricated house construction)에 의(依)한 목조주택건설(木造住宅建設)에 관(關)한 새로운 연구(硏究)가 착실(着實)하게 진행(進行)되어 큰 성과(成果)를 거두고 있어서 값 싼 주택(住宅)의 양산(量産)에 많은 도움을 주고 있음은 물론(勿論)이고 농용건축물(農用建築物)의 건설(建設)에도 크게 활용(活用)되고 있다. 더구나 8시간(時間)만에 한 채의 주택(住宅)을 건설(建設)할 수 있는 8시간건축(時間建設)(8 house construction)의 체계(體系)가 연구개발(硏究開發)되어 증가일로(增加一路)의 주택수요(住宅需要)를 메꾸어 나가고 있어서 우리나라에서도 부면(部面)에 관한 연구(硏究)가 추진(推進)되어야 할 것으로 믿는다.

Purpose and Method: In this study, a questionnaire interview survey was conducted for the victims living in the temporary house by the Pohang earthquake, and improvements were derived. Results: As a result, major improvements in terms of facilities are as follows. First, in order to expand the toilet and cooking space, the existing inner gate and the wall are removed and the width of the toilet is expanded. Minimize the inconvenience by adding a cooking table as wide as the extended toilet. Second, a separate sleep compartment is set up to secure storage space in a limited area. And the storage closet is installed below and used as a storage space. At this time, the size of the sleeping space is set to double bed size. Third, curtains and blinds are installed on both windows to secure privacy, thereby protecting privacy and psychological stability. Conclusion: If the remodeling of the temporary house proposed in this study is utilized and applied, it is possible to provide a better living environment. In addition, it is expected that it will be possible to improve the efficiency of space and overcome existing spatial limitations by minimizing inconveniences reflecting the needs of the victims.

The assembly of the modular housing is an important phase in the construction of pre-fabricated houses. However, the assembly tools that are commonly used in a work site have a disadvantage of decreasing the productivity and the quality. We have developed a exclusive tool for assembling modular parts. The structural stability of the developed tool has been verified in the previous studies. However, the experimental analysis was not conducted. This study analyzed the effect of improving the productivity and quality of the developed assembly tool. The result of the experimental analysis shows improvements in productivity and quality compared to the conventional assembly tool.

Unlike reinforced concrete(RC) construction, the primary determinant of construction schedule for precast concrete(PC) apartment buildings is the lifting equipment. To establish a dry process-centric construction schedule, this study analyzes the lifting unit process for core, internal, and external PC wall components, which differ from traditional PC components. By examining the assembly process of these wall types, the study aims to determine the construction cycle for a standard floor frame of a PC apartment building. The findings will serve as foundational data for developing construction schedules for PC apartment buildings utilizing PC walls.

최근 국내에서는 가입자 댁내까지 광케이블망이 인입되는 FTTH구축이 일반화 되고 있으며, 초고속 인터넷 서비스를 기반으로 통방융합 서비스중의 하나인 IPTV 서비스도 다양한 컨텐츠의 확보로 점차 가입자 수요가 증가되고 있다. 또한 VoIP도 통신사업자를 중심으로 일반전화 시장을 점진적으로 잠식하고 있는 추세이고, 향후 수년 내에 걸쳐 모든 가입자 댁내까지 광케이블망 구축이 완료되어 All IP화가 이루어질 전망이다. 2007년부터 전국적으로 일반주택 및 다세대주택을 대상으로 FTTH구축이 진행되고 있으며, 광간선망에서 분리되어 광배선망 분기지점에 설치되는 광접속합체 및 전주 광분기함에 설치되는 스플리터에 대한 다양한 망구성 방법 등 현재 적용되고 있는 다양한 FTTH 구축방법에 대해서 논하였다. FTTH 가입자 개통 방법에 있어서도 광옥외선을 이용하여 가입자 댁내까지 인입되는 방법 및 현장에서 직접 커백터 조립이 가능한 현장조립형 광커백터에 대한 품질확인 방법에 대해 설명 하고자 한다.

Recently, OSC (off-site construction) construction has been revitalized as a response to the decline in building quality and productivity due to lack of skilled manpower at construction sites, and PC (precast concrete) construction, a representative OSC construction, is insufficiently applied to public housing.This is the situation.In addition, in the case of general contents appearing in standard specifications, the construction standards for quality assurance remain in the 1990s and do not correspond to the current construction environment.In order to improve the quality of PC member joints, we compared and analyzed Korean and Japanese specifications to establish appropriate standards for PC construction quality control, focusing on the quality of grout used in joints.

The purpose of this study is to experimentally evaluate the structural behavior of built-up type column consisted of angles and y-shape steel sheet forms for filling concrete. This column for minimizing form working and reinforcement placing is able to improve capacity of construction and reduce the term of works. Thirteen 1/3 scaled columns were fabricated. The main variables are 1) effect of angles and y-shape steel sheets of fabricated columns, 2) slenderness of column, 3) eccentricity of column. The results show that the experimental capacity of built-up type column is similar to theoretical one by reinforcement concrete design code. The maximum loads increase according to the rate of angle to cross section of column.
