Problems solved by technology

[0002] The current prefabricated structure has become a new industry nationwide, but whether the connection to the prefabricated structure is safe and reliable, whether the prefabricated structure has actually improved efficiency, whether it has really accelerated the speed, to what extent it has improved the environment, etc. However, there are many controversies; in the assembly process of prefabricated structures, it is inevitable that the ordinary steel bars, prestressed steel bars and other rods fixed on the two butt joints will have deviations within the allowable range during the butt joint. In order to adapt to this butt joint At present, grouting sleeve connection, anchor grout lap connection and other methods are mostly used. These connection methods have disadvantages such as complicated construction technology, undetectable, unclear acceptance standards, and long waiting time to reach strength.
[0003] Another way of connecting rods such as steel bars is to use bolted connections, but bolted connections not only significantly weaken the section of the member, but also require a fixed angle of wrench rotation for bolt tightening, which requires a large space for the connecting piece
[0004] As there is no reliable and convenient connection method between steel bars and prestressed tendons of prefabricated components, the current prefabricated structure has been greatly restricted and questioned, and the assembly rate is difficult to further improve

Abstract

The invention discloses a connecter of a flexible inhaul cable offset rod part to connect an offset rod part one and an offset rod part two pre-embedded in two prefabricated parts. The connector comprises flexible inhaul cables, an inhaul cable first anchor head, first threaded sleeve tubes, an inhaul cable second anchor head, second threaded sleeve tubes, spiral reinforcements and a high slurry body; the inhaul cable first anchor head and the inhaul cable second anchor head are separately anchored at the two ends of the flexible inhaul cables, the rod part one and the inhaul cable first anchor head are separately anchored by the first threaded sleeve tubes through threaded pairs, the rod part two and the inhaul cable second anchor head are separately anchored by the second threaded sleevetubes through threaded pairs, and the spiral reinforcements are arranged around the flexible inhaul cables in a encircled mode; the high slurry body is poured into the cavity body formed by the encirclement of the spiral reinforcements, and the spiral reinforcements strengthen the anti-resistance capability of the high slurry body column. The connecter of flexible inhaul cable offset rod part issmall in size, save in material use, suitable for butting bars with a large tolerance, convenient in detection and test, and clear in acceptance standard.
