Problems solved by technology

[0002] In engineering construction, it is unavoidable that ordinary steel bars, prestressed steel bars and other rods fixed on two butt joints will deviate within the allowable range. In order to adapt to this butt joint deviation, grouting sleeve connections are mostly used at present , corrugated pipe reserved hole grouting connection and the use of connection boxes, etc. These connection methods have disadvantages such as complicated construction technology, undetectable quality, difficult to guarantee quality, and long waiting time to reach strength. If direct connection methods such as straight threaded connections are used , the positioning and manufacturing accuracy of the connecting rods are extremely demanding, the cost is high and the scrap rate is high
[0003] For example, a self-locking semi-grouting sleeve disclosed in Publication No. CN108035493 A has undergone certain improvements, but in essence it is still connected by means of high-strength grouting material forming friction and extrusion between the steel bar and the sleeve. It is difficult to detect the shortcomings of grout compactness, and the processing and assembly are more complicated
[0004] Since there is no reliable and convenient connection method between the steel bars and prestressed tendons of prefabricated components, the current prefabricated assembly structure has been greatly restricted and questioned, and the prefabricated assembly rate is also difficult to break through

Abstract

The invention relates to an elastic combination ring type anchoring offset rod piece connector. The elastic combination ring type anchoring offset rod piece connector comprises elastic combination anchoring rings, an anchoring sleeve and a pressure bearing nut combination piece; the elastic combination anchoring rings comprise at least a plurality of curved clamping pieces and an elastic resettingpiece, the anchoring sleeve includes at least one anchoring cup and a first guiding-out tightening combination piece, and the pressure bearing nut combination piece includes a pressure bearing nut and a second guiding-out tightening combination piece; the anchoring sleeve forms a multi-directional constraint and anchoring effect on the elastic combination anchoring rings, the closing-up ends of the anchoring cups are connected with a rod piece on one side, and the elastic combination anchoring rings form a one-way anchoring structure with a rod piece on the other side; the first guiding-out tightening combination piece disposed on the outer side of the anchoring cups is externally pulled, and the anchoring cups are rotated to tighten the connector, and the tension connection of the rod pieces is realized; and by pulling the second guiding-out tightening combination piece, the pressure bearing nut presses the anchoring sleeve to provide the pressure resistance of the rod pieces. The elastic combination ring type anchoring offset rod piece connector is small in size, saves materials, and is high in construction speed, convenient in detection and inspection and clear in acceptance standard.
