Problems solved by technology

The relative position between the steel strands also shifted, causing the lifting tool shaft to fail to pass through the steel strands, or to pass through the steel strands completely
At this time, the lifting causes the stress concentration of some steel strands, and there is a hidden danger of steel strand breakage

Abstract

The invention discloses a positioning device for hoisting steel strands of a box girder, which ensures that the overall position of the steel strands and the relative position of the steel strands do not deviate in the vibrating operation, so that a hoisting shaft can normally penetrate through the steel strands, and the hoisting operation is safely completed. Comprising frame bodies arranged on the two sides of a box girder formwork, each frame body is provided with a first guide groove in the longitudinal direction of the frame body, two cross arms are arranged between the frame bodies, the cross arms are matched with the first guide grooves in the frame bodies to guide the cross arms to move along the first guide grooves, each cross arm is provided with a second guide groove, and the second guide grooves are matched with the first guide grooves. The second guide groove is perpendicular to the first guide groove; two positioning plates are arranged between the two cross arms, and the positioning plates are matched with second guide grooves in the cross arms to guide the positioning plates to move along the second guide grooves; a positioning rod is arranged between the two positioning plates, and a limiting block is arranged on the positioning rod and used for limiting the steel strand.

Description

technical field [0001] The invention relates to the technical field of prefabricated roads, in particular to a positioning device for hoisting steel strands of box girders. Background technique [0002] With the development of society and economy, the traffic volume is increasing, and the requirements for the traffic road network are getting higher and higher. Especially in economically developed areas, the speed of road construction and maintenance is very high, and road construction is closely related to economic development. Prefabricated road construction has gradually been widely used, including prefabricated small box girders. Nowadays, after the prefabrication of small box girders is completed, steel wire ropes are often used to lift the whole girder. In order to simplify the hoisting process, the steel strand hoisting method is gradually adopted. [0003] During construction, after the concrete is vibrated, the overall position of the steel strand will shift. The ...
