Double-ball-hinge steering connector of offset rod member

Abstract

The invention relates to a double-ball-hinge steering connector of an offset rod member. The double-ball-hinge steering connector is used for connecting offset rod members on two embedded components.The double-ball-hinge steering connector of the offset rod member comprises a dumbbell connecting rod, a first anchoring sleeve and a second anchoring sleeve; the dumbbell connecting rod is arranged between the first anchoring sleeve and the second anchoring sleeve and is suitable for multi-directional offset between two rod members; one end of the first anchoring sleeve is connected with a rod member I directly or indirectly, and the other end of the first anchoring sleeve anchors a first spherical nut of the dumbbell connecting rod; and one end of the second anchoring sleeve anchors a secondspherical nut of the dumbbell connecting rod, and the other end of the second anchoring sleeve is directly or indirectly connected with a rod member II. The double-ball-hinge steering connector of the offset rod member is small in size, material-saving, high in construction speed, convenient in detection and inspection, definite in verification standard and capable of meeting the existing mechanical connection standard requirements.

Description

technical field [0001] The invention relates to the technical field of connection of assembled structures, in particular to a double ball hinge steering connector of an offset rod. Background technique [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.

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] For example, in the steel connection structure of prefabricated components announced by the publication number CN 106638981 A, a connection box is embedded in advance, and then the steel bars are respectively welded and bolted to the connection box to realize the connection; although this method also realizes the However, the connection box used takes up a lot of space, the force of the connection box itself is not direct enough, and when the number of butt steel bars is large, the installation and tightening of bolts and gaskets are complicated, so it is difficult to promote in a large area

[0005] 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
