Embodiment Construction

[0018] Examples see Figure 4 As shown, this prestressed steel rod mounting nut includes a fixed end mounting nut 11 and a tensioning end mounting nut 12. Both the fixed end mounting nut and the tensioning end mounting nut have a threaded sleeve, and the inner diameter of the threaded sleeve is slightly larger than The diameter of the prestressed steel rod 10, there is a section of thread 5 in the middle of the inner wall of the threaded casing, and a magnetic ring 1 is concentrically embedded on the end surface of the tail of the threaded casing. A positioning surface is formed on one side, and a positioning column 3 with a positioning column end 3.1 is fixed inwardly to the threaded section of the sleeve end of the mounting nut at the fixed end, and the positioning column end 3.1 of the positioning column is connected to the sleeve end of the threaded sleeve. Solder connection between header 4.

[0019] The end 4 is a square head, a hexagonal head or a hexagonal cylindrical...

Abstract

The invention discloses a mounting nut of a prestressed steel bar, which comprises a fixed-end mounting nut and a stretch-end mounting nut that are respectively provided with a threaded sleeve; the inside diameter of the threaded sleeve is slightly larger than the diameter of the prestressed steel bar; the middle part of the inner wall of the threaded sleeve is provided with a section of threads;the end surface of the tail part of the threaded sleeve is embedded with a magnet ring in a concentric way; the sleeve end of the threaded sleeve expands and forms a locating surface towards one sideof the tail part of a locating column; and the sleeve end of the fixed-end mounting nut is fixed with the locating column with a locating column end inwards to the thread section. The nut has simple and reliable structure, convenient manufacture and low cost, ensures the reliable installation of an anchor backing plate, simplifies the installation process of the anchor backing plate, reduces the tool kind and amount in the construction site and the labor intensity of the workers, quickens the construction progress, saves a great deal of working hours, and realizes the fast installation of theprestressed steel bar.

Description

technical field [0001] The invention relates to a nut connected to a rail plate mold and used for installing prestressed steel rods. Background technique [0002] In the past track slab prefabrication process, the mounting nuts used to connect the prestressed steel rods used ordinary nuts, and the prefabricated anchor pads used bolts to connect the anchor pads and anchor cavity molds. Due to the large number of prestressed steel rods and anchor pads, The above-mentioned operations will inevitably cause a considerable workload, making the installation efficiency low; at the same time, the axial positioning of the prestressed steel rods is all through visual inspection or with the help of measuring tools. become low. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the present invention provides a prestressed steel rod installation nut, to solve the technical problem of low installation efficiency of the prestressed steel rod and th...
