The reinforced junction hardware of turn buckle type and the reinforced junction hardware in order junction manner null

摘要

PROBLEM TO BE SOLVED: To attain a junction working state abounding in strength by tightening and unifying the opposed reinforcements of a precast reinforced concrete construction.;SOLUTION: A turnbuckle type reinforcement joint metal is composed of a pair of the reinforcements (22) in which male screws (23a) and (23b) having opposite spiral directivity are given to opposed front end sections, a pair of rotary blocks (10) with female screws (14) clamped and used to the male screws and opposed symmetric dovetail groove type wedge receiving ports (15), an approximately drum type connecting wedge (11) inserted and fitted into the wedge receiving ports of both rotary blocks, a pair of cover rings (12) constraining the connecting wedge in a manner that the connecting wedge cannot be slipped off by a slidable covering and fitting to both rotary blocks and a pair of filler plates (13) pressed in and unified to fitting voids among the cover rings and the rotary blocks. It is determined that a pair of the reinforcements can be tightened and unified mutually by rotating and operating the rotary blocks.;COPYRIGHT: (C)2003,JPO
