Sawtooth clutch lead screw anchoring spherical nut offset rod part connector

Abstract

The invention relates to an overrunning clutch lead screw anchoring spherical nut offset rod part connector, and offset rod parts connected to two embedded assemblies. The connector comprises an overrunning clutch lead screw anchoring sleeve, a second anchoring sleeve, a dumbbell connecting rod and a pressure-bearing nut assembly, wherein the dumbbell connecting rod is placed between the overrunning clutch lead screw anchoring sleeve and the second anchoring sleeve to adapt to multi-directional deviations between the two rod parts; the first rod part is anchored to one end of the overrunning clutch screw anchoring sleeve, a first spherical nut of the dumbbell connecting rod is anchored to the other end of the overrunning clutch screw anchoring sleeve; a second spherical nut of the dumbbellconnecting rod is anchored to one end of the anchoring sleeve, and the second rod part is anchored to the other end of the second anchoring sleeve, and the tensile function of the connector is realized; and the overrunning clutch lead screw anchoring sleeve is compressed tightly by the pressure-bearing nut, and the compression resistance of the connector is realized. According to the overrunningclutch lead screw anchoring spherical nut offset rod part connector, the size is small, the material consumption is reduced the construction speed is fast, the detection and inspection are convenient,the acceptance criteria is clear, and the requirements of existing mechanical connection specifications are met.

Description

technical field [0001] The invention relates to the technical field of connection of assembled structures, in particular to a sawtooth clutch screw anchoring spherical nut offset rod connector. 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. In order to adapt to this butt joint At present, grouting sleeve connection, anchor grout lap connection, and bolt connection are mostly used. These connection method...

[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 bolt connection are mostly used. These connection methods have complex construction technology, large space occupation, inability to detect, unknown acceptance criteria, and long waiting time to reach strength, etc. disadvantages

[0003] For example, the prefabricated steel bar connection structure of the famous Finnish Peikko company pre-embeds an angle steel with an end face, and then fixes one side of the steel bar on the angle steel by welding, and at the same time opens a hole on the end face, and then passes the other side of the steel bar through it. The end face is connected with bolts; although this method also realizes the connection with deviation of the butt joints, the angle steel used takes up a lot of space, the force is not direct enough, and when the number of butt steel bars is large, the installation and installation of the angle steel and bolts are difficult. Tightening is more complicated, so it is difficult to promote in a large area, and it is only used in the connection of small square columns in industrial plants.
