Description

Building vibration isolation rubber support dismounting device and dismounting method thereof Technical Field The invention belongs to the technical field of building vibration isolation rubber support dismounting and mounting, and particularly relates to a building vibration isolation rubber support dismounting and mounting device and a building vibration isolation rubber support dismounting and mounting method. Background The building shock-insulation rubber support is the shock-insulation device which is most widely applied and mature in technology. The earthquake isolation device is placed at the base part or a certain position of a building to form the earthquake isolation layer, the upper structure is connected with the lower structure, so that the earthquake energy is isolated or dissipated, the transmission of the earthquake energy to the upper structure is avoided or reduced, the safety of the upper structure, personnel and equipment in the upper structure is effectively ensured, the normal operation of indoor equipment is not influenced, the damage of the earthquake to the structure is obviously reduced, and the safety of the structure, people and property is ensured. The building shock insulation rubber support is not only an important component of a structural bearing member, but also a key component for consuming seismic energy, and plays a vital role in building safety. Under the normal service condition, the building shock insulation rubber support can ensure that the service life of the building shock insulation rubber support is similar to that of the main body structure. But in the event of fire, earthquake, corrosion or operational environmental aversions, the support performance may be reduced or lost. The building shock-insulating rubber support is formed by alternately overlapping thin steel plates and thin rubber plates and vulcanizing the thin steel plates and the thin rubber plates at high temperature and high pressure. Rubber is inflammable and easy to burn in case of fire. The shock insulation device is directly exposed in the building structure, and the rubber support can be damaged if a fire disaster happens. The building continuously bears vertical load in the use process, and simultaneously when encountering wind load, strong shock and multiple aftershock impacts, the rubber molecular chain can be broken to generate free radicals under the repeated action of mechanical stress, so that oxidation chain reaction is initiated to form a mechanochemical process, and ozone cracks are easily caused under the action of stress. In addition, the underground structure has poor ventilation and air permeability and is moist. Rubber is exposed to humid air for a long time and undergoes gradual physical and chemical changes, which degrade its performance and lose its use, a phenomenon known as aging of rubber. During the aging process of rubber, some remarkable phenomena such as softening, stickiness, embrittlement, hardening, cracking, mildew, light loss, color change and the like of the rubber are often accompanied, the physical properties of the rubber are changed, the mechanical properties of the rubber are changed, and indexes such as tensile strength, elongation at break, impact strength, bending strength, compression ratio, elasticity and the like are reduced, so that the bearing performance of the shock-insulation rubber support is affected. Secondly, when the service life of the building shock-insulation rubber support exceeds the design life or one or three situations are overlapped, the building shock-insulation rubber support must be replaced in time so as to ensure the safety of building structures, people and property. Therefore, the building shock insulation rubber support dismounting device and the dismounting method thereof which are simple in structure and reasonable in design are lacking at present, and the shock insulation rubber support which is subjected to fire, earthquake and severe working environment or loses bearing function due to the fact that the design life is exceeded can be dismounted rapidly, safely and conveniently. Disclosure of Invention The invention aims to solve the technical problems in the prior art, and provides the dismounting device for the building shock-insulation rubber support, which is reasonable in design and can be used for quickly, safely and conveniently dismounting the shock-insulation rubber support which is subjected to fire, earthquake and severe working environment or loses bearing function due to the situation exceeding the design age. In order to solve the technical problems, the invention adopts the technical scheme that the dismounting device for the building shock insulation rubber support is characterized by comprising a dismounting force application mechanism and a distance adjusting force bearing mechanism connected with the dismounting force application mechanism; The disassembly and assembly force application mechanism compr
