  • Recently, automobile parts progress with modularization, which a great many allied products are modularized. Therefore, the purpose of this study is to develope modular housing for modularization of steering gear. Generally, steering gear housing is composed of valve housing and rack housing, it is important to combine two housings. However, housing having the pipe shape is very sensitive to welding distortion, and welding trajectory is very complicated. In order to solve this subject, cooperative control by using robots was constructed. Further, we developed the dedicated system to suit modular housing based on it, and applied laser welding to there. Moreover, welding speed was controlled in the rapid curve section so that the defect in trajectory of housing was reduced to obtain sound weldment. Accordingly, produced housing by this way is presented enough withstanding pressure to $100kg/cm^2$, and roundness and straightness are measured about 10/100 and 0.9/100 respectively.

  • After World War II, modular housing was developed as a means of quickly and efficiently meeting the housing supply demand. For the past 30 plus years, efforts have been made to improve modular housing in South Korea and to increase their competitiveness in the housing market. This study investigated modular houses based on a steel framed rahem structure which provides a flexible floor plan where walls are easily reconfigured to create rooms of various sizes and functions. Similar to the factory production methods used in the automotive industry, the modular housing industry can also benefit by standardizing such aspects as building components, manufacturing and construction methods, materials, process management, and floor plans. This study examined the feasibility of using a 3m × 3m module for developing various floor plans which are easy to produce and transport. Each 3m × 3m module can be configured to meet different living needs resulting in a complete home when multiple modules are connected. The module configurations can be varied to meet ground transportation and crane limitations. This study found that a 3m × 3m steel framed modular unit is a promising step towards providing residents with plans that meet their living preferences while improving and increasing the supply of modular houses.

  • Precast concrete apartments were main stream of domestic industrialized housing around 90's, and Steel Houses applying Steel Stud technique with light weighted steel have been dominant portion since 1995. On the other hand, various building techniques including Steel Stud method and highly prefabricated and industrialized Unit method are prevailing in developed countries like Japan. Steel stud and unit box have their own merits and demerits, but the more crucial aspect is that the constant design standard should be applied in each design procedure. It entails the necessity of industrial housing development on the open system basis. In this study, the design standard for unit house will be established coping with the established preparing standard for design specifications defined by architectural law and promotion law of housing construction. That is for design standard of industrialized private housing on the open system basis. This study attempts to propose the design automation, with the method of unit construction of which the rate of pre-fabrication is the biggest, that can cope with the demand of user on the basis of open-system. Ticky-tacky is the biggest technical problem in suppling industrialization housing. Therefore, we will suggest a basic plan for design automation of unit modular housing which can raise the productivity of industrialization housing by applying open system, utilized by DB of component and unit, and solve the problem concerned about ticky-tacky.

  • The modular apartment has been completed for the first time in Korea through the national research and development (R&D) project in December 2017, and 30 households moved in. Although conditions such as technicality and constructability have to be satisfied to adopt and spread the modular apartments in the future, economic feasibility is the most important factor among the conditions. The economic feasibility of modular apartments can be compared with that of existing reinforced concrete (RC) structure apartments. It is highly important to reduce the construction cost through standardization above all. The standardization refers to establishment of national design standards and principles, and it is important for manufacturers and building companies to comply with those standards and principles. The modular construction (MC) skill in Korea is at an early adoption stage and the MC market is not widely expanded yet. Thus, the application of the MC design, which is the basis of the standardization, has not been widely accepted. However, related R&D projects are now performing mainly by the Ministry of Land, Infrastructure, and Transport to promote modular apartments in recent years and the design standardization standard (draft) is now prepared to be notified as a result of the steady research. Furthermore, pilot complexes for demonstration purpose are under construction, starting from public rental apartments. Thus, MC method-applied public rental houses will be spread in near future. This study aims to investigate the current design status in the Ga-Yang Housing as a pilot modular complex to produce and supply more economical and efficient modular houses, and analyze the problems by comparing the design standardization standards with pre-notified design standardization standards and summarize the modifications between them thereby presenting foundational data for establishment of the design standardization in the modular business industry.

  • The government has made a lot of efforts to realize 'low-carbon green growth', one of the national policy agendas, throughout the whole industries. The construction sector is not an exception, and technological developments are active to reduce energy consumption and greenhouse gas emission. In particular, buildings occupy more than 20% of the total national energy consumptions. Thus, it can be said that increasing energy efficiency of the residential buildings and reducing CO2 emission are the urgent national agenda. Moreover, as ordinary people find it more and more difficult to get a lease on housing, which has become an important social issue recently, a housing production system that can actively respond to market demands is in urgent need. To build an eco-friendly system that can maximize efficiency in construction, this study attempts to examine and analyze the modular housing production system in the county and to find its problems. By suggesting the ways to improve the system, it aims to prepare for the base to revitalize the unit modular housing production system.
