Description

Technical Field

[0002] To solve the vibration impact of rail transit on the upper building structure, laying flexible pads on the bottom floor of the building is currently a low-cost method. However, due to the need to ensure the safety and reliability of the building, the wall columns and foundation pedestals at the bottom of the structure are still fixedly connected, and flexible pads can only be laid on the bottom floor slab, so that the vibration effect can still be transmitted to the upper building through the transmission route of pile foundation-pedestal-structure wall columns, and the vibration isolation effect is greatly reduced or even ineffective.

[0003] Chinese invention patent application CN117071624A discloses an energy-absorbing vibration-reducing expanded prefabricated pile and a method for connecting it to an upper structure. The energy-absorbing vibration-reducing expanded prefabricated pile consists of an upper energy-absorbing vibration-reducing area and a lower bearing area, and a prefabricated pile passing through the axis of the two areas is provided; the upper energy-absorbing vibration-reducing area consists of a prefabricated pile and its outer periphery concentrically wrapped with modified furan resin rubber concrete and a corrugated steel sleeve; the lower bearing area consists of a prefabricated pile and its outer periphery concentrically wrapped with cement cementitious materials. The energy-absorbing vibration-reducing expanded prefabricated pile is embedded upward into the upper structure, and the pile top and the upper structure are transitioned and connected through a lower rubber pad, a sliding layer, an upper rubber pad, a steel sleeve top plate and a steel anchor nail, thereby realizing vibration reduction and vibration isolation between the pile foundation and the upper structure. The structure is simple, the mechanism of action is clear, and the vibration resistance of the pile foundation and the upper structure can be greatly improved. In the prior art, since there is still a hard connection structure between the structures, the vibration isolation effect will still produce a transmission effect along the hard connection structure, resulting in a weakened vibration isolation effect. Moreover, its technical solution does not involve a protective limiting structure for horizontal displacement.

[0047] The lower end of the structural column 1 is an enlarged column head, and a circle of first countersunk holes penetrating downwards are processed on the enlarged column head, and the countersunk end is at the top surface.

[0048] The lower end of the cap 3 is supported by the foundation pile 4, and the upper plane of the cap 3 has a first concave pit, and the bottom surface of the first concave pit is provided with an embedded steel plate 8, and the second bottom spring pad 7 is placed on the embedded steel plate 8.

[0073] The materials of the first side spring pad 6 , the second bottom spring pad 7 , the second side spring pad 15 and the third bottom spring pad 17 mentioned in this embodiment are all elastic materials that can isolate vibration.

[0074] In this embodiment, under the action of an earthquake, the recess of the cap 3 will limit the horizontal displacement of the structural column 1 , and the pressing piece 18 can effectively limit the relative separation of the structural column 1 and the cap 3 .
