    興安網(wǎng)架四孔橡膠支座多少錢(qián)

    網(wǎng)架支座是依據(jù)中華人民共和國(guó)交通行業(yè)標(biāo)準(zhǔn)《球形支座技術(shù)條件（GB/T17955-2009）及建筑抗震設(shè)計(jì)規(guī)范（GB50011-2001）鋼結(jié)構(gòu)設(shè)計(jì)規(guī)范（GB50017-2003），經(jīng)詳細(xì)的靜力學(xué)、動(dòng)力學(xué)分析研制而成的新型抗震減振鋼支座?？拐饻p振支座結(jié)構(gòu)更加合理，性能更加可靠，使用壽命更長(zhǎng)。

    Rack bearing is based on technical support conditions of People's Republic of China traffic industry standard "spherical (GB/T17955-2009) and the code for seismic design of buildings (GB50011-2001) code for design of steel structures (GB50017-2003), the static and dynamic analysis model of seismic vibration damping steel bearing rotogravuer. The seismic damping bearing structure is more reasonable, the perbance is more reliable, and the service life is longer.
    網(wǎng)架支座（又名鋼結(jié)構(gòu)支座）分為四個(gè)類(lèi)型：GKQZ型鋼結(jié)構(gòu)抗震鋼球支座、GJQZ型鋼結(jié)構(gòu)減震鋼球支座、GKGZ型鋼結(jié)構(gòu)抗震球型鋼支座、GJGZ型鋼結(jié)構(gòu)減震球型鋼支座。
    Rack bearing (aka steel bearing) is divided into four types: GKQZ type steel structure seismic steel ball bearing, ball bearing type GJQZ damping steel structure and GKGZ type seismic steel structure steel ball bearings, GJGZ type damping steel structure steel ball bearing.
    該支座包括固定支座（代碼為GD）、單向支座（代號(hào)為DX）、雙向支座（代號(hào)為SX）三種型式，22個(gè)等級(jí)，其水平承載力、豎直方向拔力及支座的整體強(qiáng)度均比普通支座有大幅度提高。該系列支座采用彈性減振元件，當(dāng)水平力大到一定程度后，減振彈簧開(kāi)始發(fā)生彈性變形實(shí)現(xiàn)緩沖作用。當(dāng)結(jié)構(gòu)發(fā)生轉(zhuǎn)角時(shí)，球芯產(chǎn)生轉(zhuǎn)動(dòng)，釋放上部結(jié)構(gòu)產(chǎn)生的轉(zhuǎn)矩。地震時(shí)，剛性抗震措施和柔性減振措施同時(shí)發(fā)生作用，以抵御巨大的地震輸入能量，這樣既能保證橋梁上、下結(jié)構(gòu)合理相對(duì)位移，減小地震力的放大系數(shù)，又使結(jié)構(gòu)保持統(tǒng)一性。該支座可抵御8-11度地震，對(duì)高烈度地震區(qū)尤其直下型地震區(qū)的工程結(jié)構(gòu)有良好的抗震減振作用。
    The bearing comprises a fixed support (code GD), one-way bearings (codenamed DX), bidirectional support (codenamed SX) three types, 22 grades, bearing capacity, the level of the overall strength of vertical pulling force and bearing are better than ordinary bearing has greatly improved. The series of supports adopt elastic damping element. When the horizontal force is large to a certain extent, the damping spring begins to deb elastically to achieve the buffering effect. When the structure rotates, the ball core rotates to release the torque generated by the upper structure. When the earthquake, the rigid and flexible measures to reduce seismic measures happen at the same time, in order to resist the earthquake b energy is huge, so as to ensure the bridge, reasonable structure displacement amplification coefficient decreases with the force of the earthquake, and the structure of unity. The support can withstand 8-11 degree earthquake, and has good seismic and vibration reduction effect on the engineering structure in high intensity earthquake area, especially in the lower earthquake zone.
