Problems solved by technology
Under the action of earthquakes, the pile top near the cap is more complicated in stress. Whether it is a rigid connection, a semi-rigid connection or a variable stiffness connection, when irreparable damage occurs at the connection between the cap and the pile body, the device at the connection is often irreplaceable

Embodiment
[0034] Such as figure 1 Shown is a composite damping device of the present invention. The main structure of this embodiment includes a pile foundation 1, a cap 2, a sleeve 3 arranged on the top of the pile foundation 1, and a steel plate 4 at the bottom of the cap 2. 1. Three rows of horizontal anchor bolts 5 are respectively driven into the left and right sides of the top, so that the sleeve 3 and the pile foundation 1 form an integral body, and the steel plate 4 is welded together with the reinforcement of the cap 2. The sleeve 3 and the pile foundation 1 are welded together. The steel plates 4 are connected with the oil damper 10 through rubber bearings.
[0035] The rubber bearing includes an internal rubber 14, an internal steel plate 15, an upper sealing plate 17, a lower sealing plate 6, an upper connecting plate 19, a lower connecting plate 8 and a rubber protective layer 16, and the lower sealing plate 6 passes through a plurality of first The bolt 7 is fixed on the ...

The invention discloses a composite damping device and a construction method thereof. The composite damping device is arranged between a pile foundation and a bearing platform and comprises a sleeve and a steel plate. The sleeve is arranged on the top of the pile foundation. The steel plate is arranged at the bottom of the bearing platform. The sleeve and the steel plate are connected through a rubber support and oil dampers. The oil dampers are sleeved with spiral springs. When a building suffers earthquakes, energy can be consumed through the composite damping device between the pile foundation and the bearing platform of the building, so that damage of the horizontal earthquakes and the vertical earthquakes to the building is relieved; and even if when the building suffers a rare earthquake or a quite rare earthquake, under the condition that an upper structure of the building is in a repairable state, if damaged, the composite damping device connected between the pile foundation and the bearing platform can be replaced rapidly, so that the function of the existing building is recovered rapidly.
Description
technical field [0001] The invention belongs to the technical field of damping control of building structures, and in particular relates to a composite damping device and a construction method thereof. Background technique [0002] Pile foundation is the foundation form commonly used in high-rise and super high-rise buildings and large-span space buildings. In traditional pile foundations, steel bars are often inserted into the cap, and concrete is poured to form a form in which the top of the pile is consolidated on the cap. Under the action of earthquakes, uneven settlement and other factors, the cap must bear the axial force and shear force transmitted from the upper structure. force, bending moment. Although this consolidation method improves the strength of the connection between the pile foundation and the cap, the consolidation connection between the pile top and the cap often causes irreversible damage such as steel bar yielding and concrete cracking due to stress c...
