Fastening device for high-strength bolt and application method thereof

Abstract

The invention discloses a fastening device for a high-strength bolt and an application method thereof. The fastening device for the high-strength bolt comprises a frame structure, a fastening platform and a plurality of movable clamping blocks. The frame structure is fixed onto the ground, and the fastening platform is rotationally connected with the frame structure; the frame structure is used for fixing the fastening platform in the horizontal direction or the vertical direction; the plurality of movable clamping blocks are selectively fixed onto the fastening platform and used for limiting and fixing a to-be-fastened connecting plate; and the movable clamping blocks and the fastening platform are detachably fixed. According to the fastening device for the high-strength bolt and the application method thereof provided by the invention, the movable clamping blocks are used for limiting and fixing the to-be-fastened connecting plate, and the movable clamping blocks are detachably fixed onto the fastening platform, so that limiting and fixing of the to-be-fastened connecting plates with different sizes are met; and the device is simple in structure and high in practicability and has operability and generalization performance.

Description

technical field [0001] The invention belongs to the technical field of bolt fastening devices, and in particular relates to a fastening device for high-strength bolts and an application method thereof. Background technique [0002] Steel structures have the advantages of high material strength and light weight, and have been widely used in building structures and other fields; with the popularity of steel structures in practical engineering, research on steel structure connectors has gradually increased in the field of scientific research. In structural research, the friction-type high-strength bolt connection pair is often used as the main part of the connecting piece. The contact surface of the component is compressed by applying a pre-tightening force to the screw, and the friction of the contact surface is used to prevent the sliding of the connecting plates to achieve transmission. The purpose of external force; research shows that: the reliability of steel structure co...
