Abstract

The invention belongs to the technical field of construction vibration isolation and particularly relates to a vibration-isolation limiting protective device. According to the technical scheme, the vibration-isolation limiting protective device comprises vibration isolation supports, connecting plates, a lower buttress, an upper buttress, mild steel dampers, connecting steel plates, pre-embedded steel plates, bolts and pre-embedded screws. The vibration-isolation supports are connected through the connecting plates on the upper surface of the lower buttress and the lower surface of the upper buttress. The pre-embedded steel plates are transversely arranged on the upper end edge of the lower buttress. The pre-embedded screws are arranged at the two sides of the pre-embedded steel plates and are perpendicular to the re-embedded steel plates. One end of each pre-embedded screw is fixed to the corresponding pre-embedded steel plate, and the other end of each pre-embedded screw is fixed to the lower buttress. The mild steel dampers are arranged on the lower buttress and located around the vibration isolation supports. The connecting plates are arranged under the mild steel dampers. The connecting plates and pre-embedded screws are fixed through bolts. The device is convenient to construct and high in safety, and has the advantages of mass industrialized production, reduced production cost, effective limiting and protection for the vibration isolation supports and the like.

Description

technical field [0001] The invention belongs to the technical field of building earthquake resistance, and in particular relates to a seismic isolation limit protection device. Background technique [0002] With the continuous development of seismic isolation technology, the United States, Japan, China, Italy and other countries have widely used foundation isolation, series isolation and layer isolation in engineering, forming a large number of isolation structures. Seismic isolation structures usually use rubber isolation bearings to form a seismic isolation layer, prolong the natural vibration period of the structure, increase damping, reduce the input of seismic energy to the superstructure, and make the superstructure move in translation without causing damage. Therefore, the function of the isolation rubber bearing is to generate a large displacement under the action of the earthquake, and then consume energy to ensure the safety of the superstructure. However, the rub...
