The present application is described in further detail below with reference to the attached drawing figures.

Example 1:

referring to fig. 1-4, the pier consolidation structure of the steel structure overpass in the embodiment of the present application includes a fixed pile 1 and a top plate 3 installed on the top of the fixed pile 1, a housing 2 installed beside the fixed pile 1 is installed on the bottom side of the top plate 3, an installation seat 5 is installed on the top side of the top plate 3, a following column b10 for drawing and fixing the traction column is movably inserted and arranged in the installation seat 5, and a press-locking device matched with the following column b10 is installed in the housing 2.

The press locking device comprises a follow-up column a8 arranged below a top plate 3 and positioned in a housing 2, two strip-shaped openings 301 are symmetrically formed in the top plate 3, a rotating shaft 14 is jointly inserted between the two strip-shaped openings 301, oblique rods 9 are sequentially rotatably sleeved outside the two rotating shafts 14, the two oblique rods 9 are respectively inserted into the two strip-shaped openings 301, the head end and the tail end of each oblique rod 9 are respectively abutted in end part annular grooves of the follow-up column a8 and the follow-up column b10, and a balance weight part attached to the top plate 3 is arranged in the housing 2; the axial lead of the follow-up column a8 is parallel to the axial lead of the follow-up column b10, one side of the follow-up column a8, which is close to the fixed pile column 1, is fixedly provided with a limiting horizontal pull pile 4, and the fixed pile column 1 is provided with a rectangular opening for the limiting horizontal pull pile 4 to penetrate and slide; the counter weight part is including fixing the hoist and mount board 11 in roof 3 bottoms, and hoist and mount board 11 internal fixation has been inserted horizontal sleeve 12, and the interlude is provided with steel wire stay cord 7 in the sleeve 12, and the one end of steel wire stay cord 7 links to each other with the outer wall of follow-up post a8 is fixed, and the lead dish 6 of the counter weight of a plurality of adjacent settings is installed to the other end of steel wire stay cord 7.

Two limit take-off side plates 15 are fixedly mounted on the outer symmetry of the follow-up column b10, one opposite sides of the two limit take-off side plates 15 are respectively attached to and abutted against two opposite inner side walls in the mounting seat 5, so that the follow-up column b10 can only move along the direction parallel to the length direction of the limit transverse pull pile 4 and cannot be taken off from the mounting seat 5.

The specific detailed implementation principle is as follows: before the hanging traction column is installed, the limiting transverse pull pile 4 is pulled outwards by a tool to enable the follow-up column a8 to be close to the fixed pile column 1, so that the follow-up column b10 moves close to one side close to the traction column to be installed, enough margin is reserved for hanging the traction column, after the hanging is carried out, the limiting transverse pull pile 4 is loosened, the follow-up column a8 is pulled away from the fixed pile column 1 under the action of the balance weight lead disc 6, and the follow-up column b10 is horizontally pressed and moves towards one side far away from the follow-up column a8 under the action of the lever of the two oblique levers 9, so that the hanging and the tensioning of the hung traction column are realized, and the hanging and the tensioning of the traction column can be convenient;

meanwhile, when the bridge body is subjected to slight vibration due to external force (wind power and the like), the traction column also slightly moves along with the slight vibration, so that the traction column pulls the follow-up column b10 to slightly move, the follow-up column b10 drives the two oblique rods 9 to perform adaptive slight swinging action, the follow-up column a8 is pressed against and moved by the two oblique rods 9, the final slight movement action can be counteracted under the action of the counterweight lead disc 6 on the follow-up column a8, and the follow-up column b10 can be restored to the original position after slight movement, so that the follow-up column b10 can be matched with the traction column to perform adaptive action under the action of the counterweight lead disc 6 and a series of transmission, the relative stability of the bridge body structure is ensured, the relative stability of the abutment and the traction column is ensured, the fracture probability of the connection between the abutment and the traction column is reduced, and the reliability is strong.

Example 2:

this example differs from example 1 in that: the sleeve 12 has been seted up the sliding support mouth to the one end of follow-up post a8, has installed the gyro wheel 13 of bracketing steel wire stay cord 7 through the round pin axle rotation in the sliding support mouth, and the bearing setting of gyro wheel 13 can be in the activity of sleeve 12 tip for the steel wire stay cord 7 corner and improves the facility, reduces the appearance of retardant condition, also can avoid the too fast wearing and tearing of steel wire stay cord 7, improves the service cycle of steel wire stay cord 7.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
