[0032] Reference Figure 1-4 A vibration isolation support structure is used for energy dissipation and vibration isolation of buildings in order to improve the installation accuracy, flatness and vibration isolation effect of the vibration isolator and prevent the deviation of the vibration isolator.

[0033] The vibration isolation support structure includes a lower pier 1, a plurality of spring vibration isolation groups, a plurality of limit platforms 2, a plurality of temporary support members 9 and a supporting steel plate;

[0034] During the construction of the top plate, the steel bars of the lower pier column 1 are embedded in advance. After the steel bars of the lower pier column 1 are tied, the formwork is supported and poured to form the lower pier column 1. A 60mm to 80mm secondary grouting leveling layer is reserved for the head of the lower pier column 1, and the secondary grouting material is used for pouring to ensure the flatness of the casting surface of the vibration isolator. During the construction of multiple limit platforms 2, the steel bars are also embedded in advance during the construction of the transfer beam structure, and finally the limit platforms 2 are cast.

[0035] Each spring vibration isolation group includes multiple anti-skid pads 7, multiple spring vibration isolators 3 and multiple leveling pads 8. Each anti-skid pad 7 is arranged on the leveling layer, each spring vibration isolator 3 is arranged on an anti-skid pad 7, and the base of each spring vibration isolator 3 overlaps with an anti-skid pad 7. Each spring vibration isolator 3 is positioned and installed by the anti-skid pad 7. Each leveling pad 8 is arranged between a spring vibration isolator 3 and the supporting steel plate. The spring vibration isolator 3 is a pre-tightened spring vibration isolator, which is released after complete installation. The spring surface of the spring vibration isolator 3 is electroplated with nickel to improve the anti-rust effect. The spring isolators 3 in each spring vibration isolation group are arranged at equal intervals to improve the vibration isolation effect.

[0036] The limit platform 2 is arranged on the top of the lower pier 1, and each limit platform 2 is located between two spring vibration isolation groups. A rubber gasket 4 is arranged above the limit platform 2. There is a gap between the limit platform 2 and the supporting steel plate. The limit platform 2 can limit the spring vibration isolator 3 to avoid deviation.

[0037] The four sides of the supporting steel plate extend out of the limit platform 2 and are placed on temporary support members 9. The temporary support members 9 are detachably arranged on the ground to temporarily support the supporting steel plate, thereby facilitating the casting of the upper pier 6. After the construction of the upper pier 6 is completed, the temporary support members 9 can be disassembled and removed. Anchor plates 5 are embedded in the upper pier 6. The supporting steel plate and the anchor plates 5 are fully welded by T-shaped welding. The welds and surfaces of the supporting steel plates are coated with anti-corrosion paint. The supporting steel plate is located above each spring isolator 3, and the lower surface of the supporting steel plate is tightly and flatly attached to the top of each spring isolator 3.

[0038] The construction process of the vibration isolation support structure:

[0039] First, the lower pier 1 is constructed. During the construction of the conversion beam of the support conversion system, the steel bars of the lower pier 1 are embedded. After the steel bars of the lower pier 1 are tied, the formwork is supported for pouring. Before pouring concrete, the connection position should be roughened and the floating slurry and debris should be cleaned. The concrete strength grade is C35. Because the spring isolator 3 has high requirements for the flatness of the foundation, a 60mm-80mm secondary grouting leveling layer is reserved at the column head when pouring the lower pier 1. The pouring process of the secondary grouting material is surface cleaning, leveling, formwork, grouting, finishing, maintenance, and demoulding. The flatness of the upper surface of the lower pier 1 is ensured by the leveling layer. The steel bars of the limit platform 2 are also embedded during the construction of the conversion beam structure. The concrete strength grade is C40. The height of the limit platform 2 is 605mm, and there is a 25mm gap with the supporting steel plate, which plays the function of anti-overturning limit.

[0040] The spring isolator 3 can be installed only when the concrete strength grade of the lower pier 1 reaches more than 80%. When installing in place, first measure and lay out, use a total station to verify the foundation elevation, mark the positioning line of the anti-skid pad 7 and the installation control axis of the spring isolator 3 on the foundation surface, make the mark, and then place the anti-skid pad 7 on the positioning line of the foundation base. The placement direction is consistent with the direction of the base of the spring isolator 3. Place the spring isolator 3 on the anti-skid pad 7 in the correct direction of the drawing. The base of the spring isolator 3 completely overlaps with the anti-skid pad 7. After all the spring isolators 3 are in place, find the positioning center of the spring isolators 3 at both ends of a row, and then use the hanging line method to adjust the horizontality and horizontal position of other spring isolators 3;

[0041] Use a level to measure the relative elevation of each spring isolator 3 as the initial data before leveling, determine the final leveling elevation after data sorting, and then adjust the elevation to the accurate value by setting or removing the leveling gasket 8. After the spring isolator 3 is finally adjusted, wrap the spring isolator 3 with a waterproof and oil-proof plastic film to keep it clean and avoid the intrusion of debris or dust. These plastic films can only be removed when the spring of the preloadable spring isolator 3 is released;

[0042] Then, a detachable temporary support 9 is set on the ground, and the supporting steel plate is placed on the temporary support 9. The four sides of the supporting steel plate extend out of the limit platform by 2100mm, so a temporary support 9 is required to avoid the supporting steel plate from being suspended in the air and to increase stability. The thickness of the supporting steel plate is processed according to the design requirements. When installed, it is tightly and flat with the top of the spring isolator 3. The supporting steel plate and the anchor plate 5 are fully welded by T-shaped welding, and the weld foot size is 12mm. After welding, it is subjected to anti-corrosion treatment: before rust removal, the supporting steel plate should be free of welding slag, burrs and splash attachments, the edges and corners should be passivated, and the visible grease and other dirt on the surface of the substrate should be removed. The two sides of the weld should be painted with a workshop primer that does not affect the welding performance. After welding, the heat-affected zone of the weld should be cleaned for a secondary surface cleaning and repainted according to the design requirements. Each coating should be carried out after the previous layer of coating is dry. After the anti-corrosion coating of the supporting steel plate is applied, the coating should be naturally cured before use;

[0043] Subsequently, concrete pouring construction is carried out above the supporting steel plate to form the upper pier 6. When pouring concrete, the ash should be poured evenly, the material should be poured lightly, and the vibration should be light so that the support system below is evenly stressed. Inspections should be carried out at any time to prevent the spring isolator 3 from being changed in position due to the impact of concrete.

[0044] Finally, release the spring of the spring isolator 3, loosen the pre-tightening bolts, and level it according to the designed elevation. After all levels are adjusted, they should be reviewed. After all installations are completed and can be used normally, remove the dust and rainproof plastic film.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
