Expert: the development of rubber industry should be more rubber products used in construction, earthquake

Experts stressed that China's rubber industry should focus on technological innovation and product development, produce more products, rubber shock, but also called for the construction industry to introduce the relevant standards, the damping rubber products included in the application of building codes.

At present, China's earthquake research and development of rubber products mainly in the automobile industry, construction industry with the rubber shock is not multi-product development. The occurrence of large earthquakes in Sichuan Province on China's rubber business has put forward higher requirements, the requirements of China's rubber industry should develop more high-tech products, rubber shock absorption.

Japan is an earthquake-prone countries, after the Kobe earthquake, Japan, have stepped up the construction of earthquake requirements, but also in large and medium-sized cities in the base isolation application of new technologies.

Base isolation technology is the level of force used was "soft" components of base-isolated building and the upper part of the basis for segregation, isolation due to the rigidity of the floor is very small, when an earthquake occurs, the isolation layer will play an "alternate", to bear Vibration caused by displacement movement, and only the upper part of the structure similar to moving. The original "just" and "earthquake" of the structure of the earthquake response is "Zoom-shaking" and the seismic base isolation structure of the reaction would be "anti-seismic structure," 1/4-1/12, has greatly enhanced the safety of the structure. "Anti-seismic structure," the story drift, so the cracks caused by the construction, damage or even collapse. Base isolation layer structure of the deformation is very small, not only do not undermine the structure of the building and renovation of buildings, facilities are intact.

At present, more isolated application component is the construction isolation rubber bearings. Isolated by a layer of rubber bearing steel with a layer of laminated layers of rubber, and processed rubber and steel will be firmly bonded together. First of all, the bearings are very high vertical load-bearing characteristics of small deformation and to ensure the safety of construction; second, bearings also have a greater level of ability to shape and shear deformation up to 250% Without damage; Third, the rubber bearings with elastic properties of reduction, post-earthquake construction will enable the automatic restoration of in-situ. Use of rubber bearing isolation of buildings, the general objectives of security can improve a level of security. The traditional architecture is the goal of maximum security "of small earthquakes are not bad, in shock repairable, the earthquake was not" reasonably designed base isolation building is usually able to do "small earthquakes are not bad, not bad in shock or slight damage, Earthquake did not lose function. " In addition, the use of isolation rubber bearings in the construction of housing, could be appropriate to reduce the upper structure of the maximum security level (generally at one time to reduce the time and a half), so that construction could make the layout more flexible and reduce the number of structural measures in the construction or by Some small pieces of the structure or the size of reinforcement (such as the thickness of the wall) so that the structure of the upper part of the construction cost savings. The development of modern science and technology have been solved, and other durable rubber aging issues, can make the life of rubber bearings used in construction to meet the requirements.
