In addition, a groove portion 713 is further formed at an outer lower portion of each angle change vertical stand 71, and an insertion protrusion portion 722 inserted into the groove portion 713 is disposed at an inner lower portion of the connecting plate 72. By being further provided, the phenomenon that the connecting plate 72 is separated upward after the construction of the both steel brackets 6 can be prevented in advance.

The angle changing vertical stand 71 further includes a reinforcing bar 714 protruding inward. In addition, the lower portion of the reinforcing bar 714 of the angle-changing vertical stand 71 constituting the one angle control connecting portion 7 is further provided with a horizontal support plate 73 in close contact with the upper portion of the piers (5).

In addition, the connecting plate 72 has a plurality of vertical protrusions having different protruding lengths on the inner side such that the inner side may be in close contact with the outer end of the angle changing vertical stand 71 according to the change angle of the angle changing vertical stand 71. Protrusions 723 are provided with a plurality of different types to be selectively installed.

On the other hand, the through connector 81 of the fixing bracket 8 is provided with at least one through assembly hole penetrating through the connecting table (91).

In addition, the outer side of the steel bracket 6 is further provided with a jack mounting plate 62 including a reinforcing rib 621 on the front and rear of the lifting jack 70 is raised, the front and rear reinforcement ribs ( 621 between the front and rear turnbuckle 631 is further provided with a jack fixing ring 63 configured to separate the front and rear to hold the hydraulic jack around.

Hereinafter, the construction process and the operation relationship of the impression bracket of the second embodiment of the present invention configured as described above are as follows.

As shown in Figures 7 to 9, in the case of the construction of the impression bracket on the shift 5, the first angle adjustment connecting portion provided on the front, rear of the one steel bracket (6) from the ground Adjust the angle of) to match the inclination angle of the angle adjustment connector 7 and the inclination angle of the upper structure (10).

In detail, the angle of the plurality of angle change vertical stand 71 constituting each angle control connecting portion 7 is made to coincide with the inclination angle of the upper structure 10. That is, loosen the nut 712 fastened to the bolt shaft 711 provided at the lower portion of the angle change vertical stand 71 to change the angle of the angle change vertical stand 71, and then attach the nut to the bolt shaft 711 again. Through the fastening process, the angle of the angle change vertical stand 71 is changed.

Then, assembling by selecting the connecting plate 72 on the outside of the plurality of angle-changing vertical stand 71 constituting the angle adjustment connecting portion (7). That is, when the connecting plate 7 is selected, the connecting plate in which the inner end of the plurality of vertical protrusions 723 formed inside the connecting plate 7 and the outer ends of the plurality of angle changing vertical stand 71 are in close contact with each other. By selecting and assembling 72, the angle of inclination of the angle adjuster 7 is made to match the angle of inclination of the superstructure 50 of the cross section.

And, as described above, the steel bracket (6) in which the angle of each angle change vertical stand 71 is changed is mounted on the upper one side of the shift (5). That is, the steel bracket (6) is mounted on one side of the shift (5) to match the direction of the stapling device (60) which is inclined on the upper portion of the shift (5). Then, the steel bracket 6 constructed as described above is positioned in the same direction as the inclined direction of the upper structure 10.

Next, two fixing brackets (8) on the upper part of the shift (5) which is an opposite position of the angle adjustment connecting portion (3) provided on the front, rear of the upper portion of the steel bracket (6) provided on one side of the shift (5). ) Is fixed using fixing means such as anchor bolts.

That is, the two fixing brackets 8 are fixed to opposite positions of the connecting plate 72 of the angle adjusting connector 7.

And by connecting the front and rear angle adjustment connecting portion 7 of the steel bracket (6) and the fixing bracket (8) corresponding to each other through the connecting means (9) to the forced bracket (6) of the shift (5) Install on one side.

Specifically, the through-holes of the two fixing brackets 8 fixed at positions facing the through-holes 721 of the connecting plate 72 of the front and rear angle adjusting connecting portions 7 of the force bracket 6 are provided. Passes through a plurality of connecting rods (91).

Then, by tightening the nut 92 to the spiral portion 911 formed on one side of each connecting rod 91 and then tightening the nut 92 to the other spiral portion 911 while tensioning the other side, a forced bracket provided on one side ( 6) is to be in close contact with one side of the piers.

Then, after completing the construction of the lifting bracket as described above, by supplying a fluid to the lifting jack 70 to raise the side of the upper structure 10 mounted on one side of the shift (5).

Therefore, as described above, by installing the steel bracket 6 on one side of the shift 5 at the same position as the direction of the upper structure 10, the tension jack 70 installed on one side of the steel bracket 6 is the upper structure 10 By raising the center of gravity of the stable to be able to stably raise the social superstructure raised inclined relative to the shift (5).

That is, in the drawing, only one steel bracket 6 is shown, but each steel bracket 6 is pulled out as the upper structure 10 on one side of the shift 5 is lifted in a state in which a plurality of steel brackets 6 are installed on the shift 5. Impression jack (70) is mounted on the to raise the center of gravity of the upper structure (10) at the same time. Therefore, when raising the upper structure 10 for socializing it is possible to stably raise while preventing the phenomenon that the upper structure is inclined to the front and rear in advance.

In other words, the lifting jack 70 positioned in the same direction as each of the teaching device 60 as the point supporting the center of gravity of the weighting device presses the center of gravity of the upper structure, thereby forming a social upper structure 10 as described above. ) Can be raised stably.

In addition, the angle adjustment connecting portion 7 provided at the front and rear of the upper portion of the steel bracket 6 can be freely adjusted, so that it can be installed on all the cross sections regardless of the inclination angle of the upper structure 1 of the cross sections. It is possible.

On the other hand, Figure 10 shows a state in which the lifting bracket of the second embodiment according to the present invention is installed at an orthogonal angle, the lifting bracket of the second embodiment according to the present invention can be installed even at an orthogonal angle, the angle adjustment connecting portion (7) The angle change vertical stand 71 is formed in the same direction as the upper structure constituting the orthogonal, and the steel bracket in the state of blocking the outside of each angle change vertical stand 71 through the connecting plate 72 2) and the fixing bracket 8 may be interconnected through the connecting rod 41.

Therefore, the impression bracket of the second embodiment according to the present invention can be installed in a shift of orthogonal as well as social.

As described above, the present invention, by making it possible to safely raise the upper structure inclined to the pier or alternating bridge in the bridge, there is an effect of providing an impression bracket that can prevent the safety accident in advance when replacing the bridge bridge device.

In addition, regardless of the installation angle and the length of the superstructure constituting the bridge, all the superstructures can be pulled up interchangeably, so that it can be used repeatedly, thereby reducing the replacement cost of the device.
