CONNECTING METHOD FOR BEAM MAIN-REINFORCEMENT FOR PRECAST BEAM AT JOINT SECTION

摘要

PURPOSE:To facilitate the execution of work by connecting the one end of a connecting iron rod temporarily to a first beam main-reinforcement via a connecting sleeve, to weld the other end of the iron rod to a second beam main-reinforcement, and after that, by filling up the connecting sleeve with mortar for main connection. CONSTITUTION:The one end 15A of a connecting iron rod 15 thrust through a penetration hole 11A4 bored through the web section 11A3 of a column steel frame 11A at a joint section 16, and the end section 12B1 of the beam main- reinforcement 12B of a first precast beam 12 are temporarily connected to each other via a connecting sleeve 14. After that, the other end 15B of the iron rod 15 is fixed to the end section 13B1 of the beam main-reinforcement 13B of a second precast beam 13 by welding. After that, the connecting sleeve 14 is filled up with mortar, and the one end 15A of the iron rod 15 is mainly connected to the end section 12B1 of the beam main-reinforcement 12B via the sleeve 14. As a result, the execution of work can be facilitated.
