CONSTRUCTION METHOD OF BASEMENT AND COLUMN AND BEAM JOINING BODY USED THEREFOR

PURPOSE:To rationalize the joining of piles, columns and struts by connecting the lower ends of core columns to the tops of concrete piles, and connecting beams to a prefabricated column and beam joining body which is fitted and inserted from the tops of the core columns to arrange. CONSTITUTION:Concrete piles 4 are driven up to a specific depth from the surface of the ground, and the lower ends 62 of steel core columns 61 are inserted in the tops 41 of them to connect before they are solidified. After that, a column and beam joining body 10, etc. formed separately of a prefabrication, etc. are fitted and inserted from the tops 63 of the core columns 61 to support them on brackets 64, and concrete 65 work for columns 6 under the brackets can be carried out, while concrete for a connection of floor beams 7 and floor slabs 8 is placed. Then, beams 7A are constructed to the insides of external walls 3, PC beams 71 are arranged to complete the floor beams 7, and excavation work for the next work is carried out. According to the constitution, the joining of piles, columns and struts can be rationalized and, at the same time, the process of work can be reduced.
