High-strength screw fastening detection device and fastening detection method thereof

Abstract

The invention relates to the technical field of structural engineering, in particular to a high-strength screw fastening detection device and a fastening detection method thereof. The high-strength screw fastening detection device comprises a supporting cylinder, a jacking device and a tensioning force detection and analysis device. The supporting cylinder sleeves a screw, and one end of the supporting cylinder abuts against a to-be-fastened structure through which the screw penetrates. The jacking device is arranged at the other end of the supporting cylinder and used for being arranged on the screw in a sleeving mode and detachably connected with the screw so as to tension the screw. The tensioning force detection and analysis device is used for obtaining the jacking displacement of the jacking device and the tensioning force of the screw, and determining whether the tensioning force of the screw before tensioning meets the design requirement or not according to the jacking displacement of the jacking device and the tensioning force of the screw. The problem that in the prior art, the fastening force cannot meet the requirement due to the fact that the fastening force of the screw is inconvenient to detect can be solved.

Description

technical field [0001] The invention relates to the technical field of structural engineering, in particular to a high-strength screw fastening detection device and a fastening detection method thereof. Background technique [0002] High-strength screw is an important component used to connect different parts of structures or equipment, and is a specific form of high-strength bolts. The pre-tightening force of high-strength screw is an important control and inspection parameter, and the pre-tightening force that does not meet the design requirements will lead to potential safety hazards of structures or equipment. For example, on a suspension bridge, high-strength screws are used to hold the cable clamp tightly on the main cable to transfer the bridge load borne by the suspension cable to the main cable. If the pre-tightening force is insufficient, problems such as cable clamp slippage may occur, affecting the bridge. Structural safety; the connection between the wind power...
