Embodiment

[0041] A one-way bolt with a controllable expansion part is characterized in that it includes a screw rod 1, a nut 2, an upper expansion part 3, a lower expansion part 4, a spring 5, a limit rod 6 and a controller 7.

[0042] The screw 1 is a rod-shaped structure with a screw thread at one end of a cylindrical surface. The threaded end is marked as end A of screw 1. A through hole I101 is opened on the cylindrical surface of the B end of the screw 1 . The cross-section of the through hole I101 is rectangular.

[0043] The upper expansion part 3 and the lower expansion part 4 are installed in the through hole I101.

[0044] The overall structure of the upper expansion part 3 and the lower expansion part 4 is L-shaped.

[0045] The upper expansion member 3 includes a horizontal structure I301 and a vertical structure I302. Both the horizontal structure I301 and the vertical structure I302 include a top surface, a bottom surface, a left side, a right side, a front side and a ...

Abstract

The invention discloses a one-way bolt with controllable expansion pieces. The one-way bolt with the controllable expansion pieces comprises a screw rod, a nut, the upper expansion piece, the lower expansion piece, a spring, a limit rod and a controller. The screw rod is of a rod structure with threads at one end of the cylindrical surface. One end with the threads is recorded as A end of the screw rod. A through hole I is formed in the cylindrical surface of B end of the screw rod. A cross section of the through hole I is a rectangle. The upper expansion piece and the lower expansion piece are arranged inside the through hole I. The upper expansion piece and the lower expansion piece are each in a L shape as a whole. The upper expansion piece and the lower expansion piece are buckled to each other through the spring. When the upper expansion piece and the lower expansion piece are fully buckled, the limit rod is located in a limit slot constructed by the upper expansion piece and thelower expansion piece. The buckled state of the upper expansion piece and the lower expansion piece is controlled by the controller.

Description

technical field [0001] The invention relates to the field of bolts, in particular to a one-way bolt with a controllable expansion part. Background technique [0002] At present, the joints between steel pipe columns and steel beams mainly include inner diaphragm joints, through diaphragm joints, outer diaphragm joints, and outer rib ring plate joints. The installation is cumbersome and requires on-site welding, and the quality of the connection is difficult to guarantee. It consumes a lot of manpower and material resources, and the labor efficiency is low. [0003] One-way bolts, also known as blind eye bolts or single-sided locking bolts, can be installed on one side and tightened on one side. They are very suitable for the connection of steel pipe structures. They have the characteristics of simple and convenient on-site construction and minimal welding volume. guaranteed. At the same time, one-way bolts have high shear bearing capacity, tensile bearing capacity and pre-...
