Abstract

The invention belongs to the field of civil engineering, and specifically relates to a bolt device capable of being simply screwed after being placed in one direction. The bolt device capable of being simply screwed after being placed in one direction is applicable to connection of a closed section component in single-side screwing in construction. A torsional shearing type self-locking single-edge bolt fastening part comprises a torsional shearing type circular head bolt rod, a tapered sleeve body, an inner sleeve, an outer sleeve, a spacer and a nut, wherein one end of the torsional shearing type circular head bolt rod is provided with a circular head cap, and the other end of the torsional shearing type circular head bolt rod is a wabbler; one end, close to a bolt cap, of the inner sleeve is a resisting body; three or four axial cracks are formed in one end, close to the resisting body, of the inner sleeve; and the nut is engaged with the torsional shearing type circular head bolt rod through screw threads. The torsional shearing type self-locking single-edge bolt fastening part is convenient to mount, easy to implement, and quick to mount.

Description

technical field [0001] The invention belongs to the field of civil engineering, and in particular relates to a bolt device which can be tightened by being placed in one direction, and is suitable for the connection of closed cross-section members in buildings for one-side tightening. Background technique [0002] At present, in the field of civil engineering, bolt connection is one of the main connection forms of steel structure nodes. Compared with other connection forms such as welding, it has significant advantages in anti-seismic and other aspects, and the factory processing of bolts is standardized and modularized. , Green and environmental protection, in line with the development trend of green industrialized buildings. There is a great demand for the installation of structural component connections in engineering construction, but as far as bolts are commonly used at present, workers need to work on both sides of the component at the same time during installation, tha...
