Document Type and Number:
WIPO Patent Application WO/2017/185193
Kind Code:
A1
Abstract:
A double-eccentric-block connecting joint for connecting steel bars of reinforced concrete precast members, consisting of a steel bar joint (1) of a reinforced concrete precast member X; a steel bar joint (2) of a reinforced concrete precast member Y; an eccentric block (3) having an inner screw thread and an outer screw thread; an eccentric block (4) having two inner screw threads; a connecting sleeve (5); and a fastening bolt (6). According to the invention, the position deviation between the steel bar joints of the two precast members is adjusted by means of the two eccentric blocks, and then the eccentric block having an inner screw thread and an outer screw thread and the eccentric block having two inner screw threads are connected by means of the connecting sleeve, and finally the fastening bolt is tightened, enabling the steel bars of the member X and of the member Y to be connected together. The connecting joint adapts to the members having a large installation deviation, can be applied in all weather condition, has reliable connection and is easy to check intuitively.
