Device for isolating horizontal earthquake and vertical vibration for building

Abstract

The invention discloses a device for isolating horizontal earthquake and vertical vibration for a building. The device comprises a vibration isolation device and an earthquake isolation device, wherein the vibration isolation device comprises an upper roof, a vertical spring array, a horizontal limiting bolt screw and a middle plate; the upper roof is connected with an upper buttress pre-buried positioning plate through a connection component; the vertical spring array is composed of multiple springs and arranged between the upper roof and the middle plate; the springs sleeve the outer side of the horizontal limiting bolt screw; the horizontal limiting bolt screw is fixed on the upper surface of the middle plate; the lower surface of the middle plate is fixedly connected with the earthquake isolation device; the earthquake isolation device comprises multiple layers of thin-layer rubber, multiple layers of thin-layer steel plates and a lower bottom plate; the thin-layer rubber layers are overlapped, and the thin-layer steel plates are clamped between every two adjacent rubber layers; and the lower bottom plate is connected with the lower buttress pre-buried positioning plate through a connection device. According to the invention, the functions of horizontal earthquake isolation and vertical vibration isolation can be realized at the same time; and moreover, the cost of the device is relatively low, and total investment in vibration isolation and earthquake isolation can be greatly reduced.

Description

technical field [0001] The invention belongs to the design fields of industrial buildings, civil buildings, bridges, etc., and in particular relates to a device for isolating horizontal earthquakes and vertical vibrations for buildings. Background technique [0002] my country is a country with frequent earthquakes. In recent years, major earthquakes have occurred in Wenchuan and Ya’an successively. The earthquakes caused a large number of casualties and huge property losses. Casualties continued due to damage to infill walls and renovation substructures. Therefore, at the government level, it has been mentioned many times to recommend the promotion of seismic isolation technology to improve the seismic performance of structures to ensure the safety of personnel. In some areas with high design intensity, it is mandatory to adopt seismic isolation technology for important buildings, which greatly promotes seismic isolation in my country. technology development. At present, th...

Problems solved by technology

[0004] After investigation and according to several similar design projects participated by the patent applicant, most of the domestic projects only use the seismic isolation technology to solve the horizontal seismic problem of the superstructure, which improves the horizontal seismic performance of the superstructure structure, while the vibration impact of the subway is not affected. It can be effectively controlled. Only a few projects have appropriately reduced the vertical stiffness of the isolation bearing by increasing the height of the isolation bearing. effective control of
