On May 16, branch of products of rubber of Chinese Society of Rubber Industry sponsors rubber products technology developed forum to be held successfully in Qingdao 2008, share 51 units, 67 delegates are attended.
Vice-chairman of Chinese Society of Rubber Industry held secretary-general concurrently to Mr Fan Rende attends the meeting and make important speech. Mr Fan Rende emphasizes pointing out in the speech, company of our country rubber should pay attention to innovation of science and technology and product development, production gives more shock-proof balata products, also appeal construction industry can publish relative standard at the same time, bring into balata damping product in building code application.
At present the research and development of shock-proof balata product of our country basically is centered in auto industry, the building develops Debuduo with the shock-proof balata product of the industry. The especially big earthquake that happens this in Sichuan raised taller requirement to company of our country rubber, company of rubber of requirement our country should develop the balata damping product of more hi-tech content.
Japan is many state that delivers an earthquake, be in after experiencing shock of slope god earth, japanese whole nation strengthened shock-proof to architectural requirement, and in large and medium-sized the city applied a foundation to lie between shake new technology.
The foundation lies between shake technology is to use horizontal power very the component lying between shake of " soft " keeps apart upside building and foundation, the stiffness as a result of the layer that lie between shake is very small, when seismic happening, the layer that lie between shake separates play " the function of " , bear the earthquake moves the displacement that cause to move, and upside structure makes approximate translation only. The seismic reaction of structure of original aseismatic " of " of sex of " firm " is " enlarge rock " , and the seismic reaction that the foundation lies between shake structure is " only the 1/4 of aseismatic structure " - 1/12, raised structural safety to spend greatly. "The displacement between the layer of aseismatic structure " is big, cause architectural craze so, destroy collapse even. Be out of shape between the layer that the foundation lies between shake structure very small, build a structure to won't be destroyed not only so, and inside the building decorate, establishment also keeps in good condition.
The component lying between shake with at present more application is to build pedestal of the balata that lie between shake. By an armor plate superposition of layer of an oak sub rises pedestal of the balata that lie between shake, pass treatment general balata and spring firm felt is together. Above all, the pedestal that lie between shake has very tall vertical stroke to bear the weight of character and very small compression are out of shape, can ensure architectural is safe; The 2nd, the pedestal that lie between shake still has larger horizontal form capacity, cut wind shear form to be able to be achieved 250% and do not destroy; The 3rd, balata lies between shake pedestal to have stretch restoration character, can make build automatic extensive to recover from an illness after the earthquake. Use the structure of pedestal of the balata that lie between shake, fortify target can improve grade of a fortify commonly. Target of traditional architectural fortify is " small shake is not bad, shake can be repaired in, big shock does not pour " , and the basis with rational design lies between shake building to be able to accomplish " normally small shake is not bad, in shake is spent not bad or gently destroy, big shock does not lose functional " . In addition, use the house that pedestal of the balata that lie between shake builds, the fortify level that can reduce upside construction appropriately (can reduce commonly arrive for a time for a time half) , make the building is decorated likely so more agile, the tectonic measure that can reduce a few constructions or the size that reduce a few structural member or match veins that stand out under the skin (ply of the body that be like a wall) , make upside structure can managing thereby partial earth creates value. The development of modern science and technology already solved the fast problem such as the ageing of balata, the life that can make balata lies between shake pedestal completely satisfies the requirement that the building uses.
