| With the rapid development of China national economic and technological and speed up construction of urbanization, the number of the new housing project will still continuing rapid growth in a long period of time. Small towns housing construction has been a brick as the main load-bearing materials, due to forbiden of the clay brick usage, the traditional construction methods has to be changed. Prefabricated construction technology of small parts of special-shaped column structure, the building system suitable for construction joint of urban and rural demand, in line with the requirements of structure type6layers and6layers below and all kinds of residential bottom, small parts on transportation and lifting restrictions on small, special-shaped columns is not indoor column edge is especially suitable for residential, economical and practical.Based on review and current situation of the development of world foreign prefabricated structure at home, combined with continued research senior fellow apprentice study, to the office building as the engineering background, the prefabricated small parts of special-shaped column construction technology mainly for the following research:(1) The original wall construction system improvement as the column bearing system, the structure system research, conceptual integration bearing components--column and wall of improved component, section design, optimization;(2) The second chapter discusses the improvements due to small parts construction joint variable, this research adds to the key construction technology of components of the horizontal and vertical elements are researched.;(3) Research on structural connection chapter third parts; the connection to the special-shaped column-shaped column; column and composite beam, composite beam with laminated plate connected the system research on the connection of;(4) Combined with the background of engineering, the prefabricated small parts of special-shaped column housing design scheme, including architectural design, component split node design and connection design, through the design to meet a set of pre-industrialized construction way of assembly type small parts-shaped column structure system.The development of this research will help promote our prefabricated small parts of the special-shaped column structure system construction technology, has the important theory significance and practical value. |
