Example Embodiment

[0020] Such as Figure 1~3 As shown, a torsion shear type self-locking high-strength one-way bolt connection pair includes torsion shear type bolt rod 1, sleeve 2, nut 3, flat washer 4 and spring washer 5; one end of the torsion shear type bolt rod 1 is provided There is a torsion shear groove 6, and the other end is provided with a tapered bottom 7; one end of the casing 2 is provided with a slot 8; the maximum diameter of the tapered bottom 7 is smaller than the outer diameter of the casing 2; The gasket 4 and the sleeve 2 are manufactured integrally.

[0021] The use method of the above torsion shear type self-locking high-strength one-way bolt connection pair includes the following steps:

[0022] 1) According to the design requirements of the bearing capacity and the connection aperture of the steel plate 10 to be connected, the torsion shear type self-locking high-strength one-way bolt connection pair of the corresponding strength level, diameter and length is selected;

Abstract

The invention belongs to the field of civil engineering, is suitable for industrial and civil buildings, bridges, tower and mast structures, boiler steel structures, hoisting machines and other steel structures, and particularly relates to a torsional shear type self-locking high-strength one-way bolt connecting pair and a using method thereof. According to the technical scheme, the torsional shear type self-locking high-strength one-way bolt connecting pair comprises a torsional shear type bolt rod, a sleeve, a nut, a flat washer and a spring washer; a torsional shear groove is formed in one end of the torsional shear type bolt rod, and a conical expanded bottom is arranged at the other end; an open groove is formed in one end of the sleeve; the maximum diameter of the conical expanded bottom is smaller than the outer diameter of the sleeve. The torsional shear type self-locking high-strength one-way bolt connecting pair and the using method thereof are suitable for being installed on a closed section or a section allowing single-face operation only, and it is avoided that structural section is weakened.

Description

technical field [0001] The invention belongs to the field of civil engineering, and is applicable to industrial and civil buildings, bridges, mast structures, boiler steel structures, hoisting machinery and other steel structures, and specifically relates to a torsion-shear type self-locking high-strength one-way bolt connection pair and its Instructions. Background technique [0002] In the current installation of steel structures, high-strength large hexagon head bolts for steel structures or torsional shear-type high-strength bolts for steel structures are mostly used for connection pairs. The advantages are convenient operation and high connection strength. They are common connection methods, but the connection The position is limited, and double-sided operations are required, and both sides should have a certain operating space, resulting in problems such as the need to open connecting holes in the closed section, which weakens the structural section. Contents of the ...
