Reinforced steel bar mechanical anchor docking connection joint structure and construction method thereof

Abstract

The invention discloses a reinforced steel bar mechanical anchor docking connection joint structure which comprises steel wires, a middle force transferring steel part, two reinforced steel bars in docking connection with the two ends of the middle force transferring steel part, and mechanical anchoring components covering the docking portions of the middle force transferring steel part and the reinforced steel bars. The mechanical anchoring components are anchored outside the middle force transferring steel part and the reinforced steel bars through straight threads, and circumferential concave parts are arranged on the positions, corresponding to the docking portions of the middle force transferring part and the reinforced steel bars, of an outer wall. One ends of the steel wires are fixedly connected with the mechanical anchoring components, and the other ends of the steel wires extend to be connected with an anchoring tension device after being wound on the concave parts. Comparedwith a traditional reinforced steel bar docking connection method, the mechanization level is high, the end face contact of the reinforced steel bars at the upper end and the lower end and the middleforce transferring steel part is compact, and internal force transferring is obvious. The mechanical anchoring components enable the reinforced steel bars and the joint structure to be integrated together through the straight threads, anchoring is compact, and the problem that the operation space is insufficient when multiple tensioned reinforced steel bars are mechanically anchored in a traditional way is solved.

Description

technical field [0001] The invention relates to a prefabricated assembled structure, in particular to a steel bar mechanical anchor butt joint structure and a construction method thereof. Background technique [0002] The prefabricated structure has the advantages of high level of mechanization, good component quality, fast construction progress, low labor intensity, and is conducive to environmental protection. It can realize the industrial production of buildings and has been widely used in many developed countries. When the prefabricated components are assembled on site, the key steel bars between the prefabricated components need to pass certain structural measures to ensure the reliability of the connection. The connection mode of nodes is the core issue of prefabricated concrete structures, and only reliable connections can ensure the safety of the structure. At present, the butt joint connection method of the main stressed steel bars of prefabricated concrete members...

AI Technical Summary

Problems solved by technology

The butt joint of stressed steel bars in the grouting sleeve is prone to joint deviation, and the force transmission performance is poor, especially when the longitudinal stressed steel bars are butt jointed, the force transmission requirements cannot be met

Traditional threaded mechanical anchors usually have thread looseness, and cannot provide enough operating space when multiple stressed steel bars are docked at the same time, which brings certain difficulties to the construction
