Abstract

The invention provides a swivel body spherical hinge position control device for bridge construction applied to the technical field of the bridge construction auxiliary equipment. The lower end face of a spherical hinge body (1) of the swivel body spherical hinge position control device for bridge construction is provided with a spherical hinge dorsal rib (3), the welded plate piece I (5) of the connecting steel plate I (4) is connected with the spherical hinge dorsal rib (3) in a welded mode, a adjusting plate I (6) of the connecting steel plate I (4) is provided with a connecting hole I (7), the lower end of a bolt I (8) is fixedly connected with a steel angles of the top of the support (2), the bolt I (8) penetrate through connecting hole I (7), the bolt I (8) is screwed and sleeved with a clamp nut I (9) and a adjusting nut I (10). According to the swivel body spherical hinge position control device for bridge construction, the structure is simple, the height and the horizontal position of the swivel body spherical hinge can be adjusted in place fast and conveniently, the fact that the position of the spherical hinge is the regulation precision and accuracy is insured, the difficulty of adjusting the position of the spherical hinge is lower in the construction process, and the construction progress is improved effectively.

Description

technical field [0001] The invention belongs to the technical field of bridge construction auxiliary equipment, and more specifically relates to a position adjustment device for a swivel ball joint used in bridge construction. Background technique [0002] With the vigorous development of my country's transportation field, the proportion of long-span bridges is increasing. Because the long-span bridge constructed by the swivel method does not affect the operation of existing roads or railways, the construction safety is good, the construction quality is easy to control, and the construction cost is low. Therefore, the large-span prestressed concrete continuous beams constructed by the swivel method have already been It is widely used in the construction of some bridges spanning existing roads or existing railways. In terms of total project construction cost, compared with bridges of the same scale, construction measures and related safety costs will be greatly reduced due t...
