It provided the amount of work area in the field and Preflex ganghyeong by a two to one modification of the extra load for the transverse support devices, such as the installation to certain pre-flex ganghyeong the conventional method of making a pre-flex type with two modifications interval connected to the cross beam can prevent lateral buckling and twisting, and in particular one ganghyeong the connection part design point through to gingyeol bolt to be cross beam, and by installing the load against the center of the cross beam the behavior of this position as a simple point be able recent method and two ganghyeong after connecting to the cross beam of the predetermined interval 'U' shaped base and one otherwise develop in a to a 2 mod was stomach, and the other is temporarily connected to the flange by bolts or welding ganghyeong of the side by side in the horizontal two locations that during loading point of Preflex ganghyeong the design profile reflection load, that is simple gait Preflex ganghyeong If it ganghyeong to both ends, in the case of inner spans Preflex ganghyeong for the location of about L / 5 from each ganghyeong end, and in the case of pre-flex ganghyeong for outer span is from about L / 5 position from ganghyeong end and ganghyeong end each other through to gingyeol bolt and loop reflection loading point two places, that is, a simple gait Preflex ganghyeong is from about L / 3 position from the ganghyeong end, and in the case of pre-flex ganghyeong for lateral span from about L / from ganghyeong end 4 and about L / from the second position to install between ganghyeong the yuapjaek to load the second program reflected load in the form-open the two ganghyeong not relatively unaffected in chapter structural size than the conventional method 2, adapted for one-time, that is, 4 can create a pre-flex type of right broom it can significantly shorten the production of air and a method for loading the installation problems of the development, especially in recent years, with the upper end of the assembly difficult ganghyeong Cloud installation and disassembly problems, and upon placing of the bottom flange concrete ganghyeong of the bottom of the dice only the aggregate between the narrow width of the bottom can be solved the problem such as that to be sufficiently filled as straight print reflection-type as well as the curve Preflex type simple beam and manufacturing method of a continuous beam structure for pre-flex type of manufacturing is also the load connection, the load reflection profile as possible transverse
