Exemplarily, the lifting legs 3 are arranged at the end of the positioning crossbar 1. The supporting longitudinal bars 2 include at least two, at least two supporting longitudinal bars 2 are arranged in parallel and horizontally, and the supporting longitudinal bars 2 span the top of the lower pier 5 and are supported on the two positioning crossbars 1, for supporting the seismic isolation bearing 6 and receiving the load transmitted from the seismic isolation bearing 6.

[0047] The process of installing the seismic isolation support 6 using the positioning plate-free seismic isolation support installation device provided in the embodiment of the present application is as follows:

[0048] S1.

[0049] S2. Determine the position of the lifting legs 3 and fix the four lifting legs 3 on the foundation; install two positioning cross bars 1 on the lifting legs 3 on both sides of the steel cage of the lower pier 5 respectively. During the installation process, use the theodolite and total station to mark the axes of the X-axis and Y-axis of the design position of the seismic isolation bearing 6 on the positioning cross bar 1, level the positioning cross bar 1, and cross the supporting longitudinal bar 2 above the steel cage and support it on the two positioning cross bars 1;

[0050] S3. Mark the center line of the seismic isolation support 6 on the flange plate at the bottom of the seismic isolation support 6, mark the axis position of the seismic isolation support 6 on the supporting longitudinal rod 2, hoist the seismic isolation support 6 to its position on the supporting longitudinal rod 2, and align the marked line on the flange plate at the bottom of the seismic isolation support 6 with the marked line on the supporting longitudinal rod 2;

[0051] S4. Construct the embedded parts in the lower pier 5 and weld them to the main reinforcement of the steel cage, and then tie the steel cage; install the formwork outside the steel cage, pour concrete in the formwork, and after the concrete strength reaches the requirement, remove the formwork and the positioning plate-free seismic isolation bearing installation device.

[0052] When the template and the positioning plate-free seismic isolation bearing installation device are removed, the superstructure 7 can be constructed on the seismic isolation bearing 6, and the removed positioning plate-free seismic isolation bearing installation device can position and install the next seismic isolation bearing.

[0053] The positioning plate-free seismic isolation bearing installation device provided in the embodiment of the present application is used to position and install the seismic isolation bearing. After the installation of the seismic isolation bearing is completed, the entire installation device can be dismantled for reuse, thereby improving the utilization rate of the entire installation device and reducing the installation cost. The positioning plate-free seismic isolation bearing installation device provided in the embodiment of the present application is not affected by the closing of the pier mold and the pouring of concrete during use, thereby ensuring the installation accuracy of the rear seismic isolation bearing.

[0055] In some embodiments, see Figure 1 , Figure 4 The supporting longitudinal rod 2 is connected to the positioning cross bar 1 through the first fastening assembly 4. In this way, when the seismic isolation bearing 6 is hoisted and placed on the supporting longitudinal rod 2, the displacement of the supporting longitudinal rod 2 due to accidental contact with the supporting longitudinal rod 2 can be avoided.

When the supporting longitudinal bar 2 is placed on the positioning crossbar 1 and the position is adjusted, the fixing bolt 41 is first passed through the crossbar bolt hole 11 and the longitudinal bar bolt hole 21, and then the fixing nut 42 is screwed on the fixing bolt 41. After tightening the fixing nut 42, the positioning crossbar 1 and the supporting longitudinal bar 2 are firmly connected together.

[0060] In some embodiments, see Figure 2 , Figure 3 When the longitudinal support rod 2 is disassembled from the positioning cross bar 1, it is only necessary to loosen the fixing nut 42 and move the longitudinal support rod 2, so that the fixing bolt 41 can be disengaged from the longitudinal support rod bolt hole 21, and then the longitudinal support rod 2 can be quickly disassembled from the positioning cross bar 1, thereby improving the disassembly efficiency of the longitudinal support rod 2.

When in use, the column base plate 31 is used to connect to the foundation through expansion bolts to transfer the load from the supporting column 32. The supporting column 32 provides a certain height and accepts the load from the lifting assembly 33. The lifting assembly 33 is used to support the positioning crossbar 1 and to drive the positioning crossbar 1 to rise and fall; through the cooperation of the two lifting assemblies 33, not only the elevation of the positioning crossbar 1 can be adjusted, but also the positioning crossbar 1 can be leveled.

[0063] In some embodiments, see Figure 6 The lifting assembly 33 includes an adjusting screw 331 and a first adjusting nut 332.

[0064] Exemplarily, the adjusting screw rods 331 include two adjusting screw rods 331, which are respectively arranged on both sides of the web of the positioning cross bar 1. The positioning cross bar 1 is supported on the first adjusting nut 332, and by rotating the first adjusting nut 332, the position of the first adjusting nut 332 on the adjusting screw rod 331 can be adjusted, thereby adjusting the height of the positioning cross bar 1.

[0065] The lower end of the adjusting screw rod 331 can be connected to the supporting column 32 by welding, thread connection or the like.

[0066] In some embodiments, see Figure 6 The lifting assembly 33 further includes a connecting plate 333 and a second adjusting nut 334; the connecting plate 333 is fixed to the upper end of the supporting column 32, and a second positioning hole 335 is provided on the connecting plate 333 for the adjusting screw 331 to pass through; the lower end of the adjusting screw 331 passes through the second positioning hole 335, and the second adjusting nut 334 is threadedly connected to the adjusting screw 331 and contacts the top of the connecting plate 333.
