In-situ casting and prefabrication combined vibration-isolated foundation and construction method thereof

Abstract

The invention provides an in-situ casting and prefabrication combined vibration-isolated foundation and a construction method thereof. The in-situ casting and prefabrication combined vibration-isolated foundation comprises a first structure, a second structure and a third structure, wherein the first structure comprises a cast-in-situ shell and a first vibration-isolated cushion layer laid in the cast-in-situ shell; the second structure comprises a prefabricated middle body installed in the cast-in-situ shell and a second vibration-isolated cushion layer laid in the prefabricated middle body; and the third structure comprises a prefabricated inner core which is installed in the prefabricated middle body and arranged on the second vibration-isolated cushion layer. The construction method of the in-situ casting and prefabrication combined vibration-isolated foundation comprises the steps that the first structure is constructed on a building foundation, specifically, the cast-in-situ shell is cast in situ and constructed, and the second vibration-isolated cushion layer is laid in the cast-in-situ shell; the second structure is constructed, specifically, the prefabricated middle body is hoisted onto the first vibration-isolated cushion layer, and the second vibration-isolated cushion layer is laid in the prefabricated middle body; and the third structure is constructed, specifically, the prefabricated inner core is hoisted onto the second vibration-isolated cushion layer. By adoption of the in-situ casting and prefabrication combined vibration-isolated foundation and the construction method thereof, the problems that according to a traditional vibration-isolated foundation, the space between every two adjacent layers is small, formworks and tied rebars are inconvenient to mount and dismount, and the construction efficiency is low are solved.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a seismic isolation foundation combined with cast-in-place and prefabrication and a construction method thereof. Background technique [0002] Base isolation in construction engineering is to add an isolation structure with a small thickness but sufficient reliability between the building foundation and the upper structure to control the transmission of ground motion to the upper structure. During vibration, its energy can be fed back to the ground or Absorbed by the seismic isolation layer, so as to greatly reduce the vibration response of the upper structure and components, ensure the overall safety of the building, prevent internal equipment from being damaged or lose its function, and indoor personnel will not be injured or feel a strong shock. [0003] The traditional construction of foundation isolation is to set up formwork, tie steel bars, and pour concrete on each fl...
