(2)The wire of each lower mechanical anchorage element is pulled out, is connected on anchoring puller system, by each lower mechanical The wire of anchorage element applies pulling force simultaneously, by each lower mechanical anchorage element together with the Bar Anchorage of lower end;
(3)Further apply pulling force to each wire to adjust so that the end of each lower end bar is with intermediate power transmission steel part under Terminal tool anchorage element anchors consolidation;
(4)Upper component is lifted into above node, upper end bar alignment is inserted into upper mechanical anchorage element;
(5)The wire of each upper mechanical anchorage element is pulled out, is connected on anchoring puller system, by more wires Apply pulling force simultaneously, by each upper mechanical anchorage element together with the Bar Anchorage of upper end;
(6)It is further adjusted by applying pulling force to every wire so that the end of each upper end bar and intermediate power transmission steel Part anchors consolidation with upper mechanical anchorage element.
Further, step(3)(6)The pulling force for adjusting wire reaches the 50% of wire tensile strength.
Advantageous effect:The present invention is using intermediate power transmission steel part and upper and lower two mechanical anchor components, by anchoring pulling force dress It sets and pulling force is applied to the high-strength steel silk thread on mechanical anchor component, steel bar stress is carried out docking with intermediate power transmission steel part to be connect, A kind of reinforcing steel bar machinery anchor docking connecting node construction is constituted, and can pulling force be applied to more high-strength steel silk threads simultaneously, may be implemented More reinforcing bars anchor simultaneously.The present invention compares traditional steel reinforcement abutting joints connection method, and Mechanization Level is high, the steel of top and bottom Muscle contact closely knit with intermediate power transmission steel part end face, and internal force transmits clearly;It can be by reinforcing bar and section by straight thread mechanical anchor component Point constructing apparatus combines together, anchors consolidation, and it is insufficient can to solve operating space when more steel bar stress tradition machinery anchorings Problem.
