球形網架結構
一、 球(qiu)形網(wang)架(jia)結構(gou)(gou)是按(an)照(zhao)一定的(de)網(wang)格形式(shi)由(you)網(wang)架(jia)桿件與(yu)實(shi)心(xin)節點(dian)鋼(gang)球(qiu)通過(guo)(guo)高強螺栓連接組(zu)合而(er)成(cheng)的(de)一種空間結構(gou)(gou)形式(shi)。我國于1978年(nian)開(kai)始從國外引進螺栓球(qiu)網(wang)架(jia)結構(gou)(gou)技術和產品,通過(guo)(guo)長期(qi)實(shi)踐,作為(wei)成(cheng)熟的(de)建(jian)(jian)筑(zhu)結構(gou)(gou)形式(shi),球(qiu)形網(wang)架(jia)結構(gou)(gou)已在(zai)國內外建(jian)(jian)筑(zhu)行業得到(dao)了十分廣泛的(de)應用(yong)(yong)。其特(te)點(dian)為(wei):自重輕(qing)、跨度(du)大、平面形狀設計(ji)靈活、施(shi)工定位簡單(dan)、安裝方式(shi)多樣等。特(te)別(bie)適用(yong)(yong)于大曲率(lv)空間結構(gou)(gou)系統如:桶殼結構(gou)(gou)、球(qiu)殼結構(gou)(gou)、各類建(jian)(jian)筑(zhu)造型等。
二、球(qiu)(qiu)(qiu)形(xing)(xing)網(wang)(wang)(wang)架(jia)(jia)(jia)(jia)結(jie)(jie)(jie)構(gou)因其(qi)結(jie)(jie)(jie)構(gou)新穎,受力(li)合理,自(zi)重輕(qing)、用(yong)(yong)鋼量低(di)等(deng)優點。如大型體育(yu)場(chang)(chang)館球(qiu)(qiu)(qiu)形(xing)(xing)螺(luo)栓(shuan)球(qiu)(qiu)(qiu)網(wang)(wang)(wang)架(jia)(jia)(jia)(jia)、公共場(chang)(chang)館球(qiu)(qiu)(qiu)形(xing)(xing)網(wang)(wang)(wang)架(jia)(jia)(jia)(jia)、電(dian)廠(chang)螺(luo)栓(shuan)球(qiu)(qiu)(qiu)網(wang)(wang)(wang)架(jia)(jia)(jia)(jia)、水泥(ni)工(gong)(gong)(gong)業球(qiu)(qiu)(qiu)形(xing)(xing)網(wang)(wang)(wang)架(jia)(jia)(jia)(jia)、倉(cang)儲物流球(qiu)(qiu)(qiu)形(xing)(xing)網(wang)(wang)(wang)架(jia)(jia)(jia)(jia)、干煤棚(peng)工(gong)(gong)(gong)業球(qiu)(qiu)(qiu)形(xing)(xing)網(wang)(wang)(wang)架(jia)(jia)(jia)(jia)、收費(fei)站(zhan)加(jia)(jia)油站(zhan)球(qiu)(qiu)(qiu)形(xing)(xing)網(wang)(wang)(wang)架(jia)(jia)(jia)(jia)、展覽中心、影劇院(yuan)、商場(chang)(chang)、航站(zhan)樓、候車(che)廳、工(gong)(gong)(gong)廠(chang)車(che)間、倉(cang)庫、電(dian)視塔等(deng)球(qiu)(qiu)(qiu)形(xing)(xing)螺(luo)栓(shuan)球(qiu)(qiu)(qiu)節(jie)(jie)點網(wang)(wang)(wang)架(jia)(jia)(jia)(jia)。國內(nei)球(qiu)(qiu)(qiu)形(xing)(xing)網(wang)(wang)(wang)架(jia)(jia)(jia)(jia)結(jie)(jie)(jie)構(gou)主要分為(wei):焊接球(qiu)(qiu)(qiu)節(jie)(jie)點網(wang)(wang)(wang)架(jia)(jia)(jia)(jia)及螺(luo)栓(shuan)球(qiu)(qiu)(qiu)節(jie)(jie)點網(wang)(wang)(wang)架(jia)(jia)(jia)(jia)兩種。螺(luo)栓(shuan)球(qiu)(qiu)(qiu)節(jie)(jie)點網(wang)(wang)(wang)架(jia)(jia)(jia)(jia)其(qi)構(gou)件工(gong)(gong)(gong)廠(chang)內(nei)加(jia)(jia)工(gong)(gong)(gong)量較大,現場(chang)(chang)安裝便捷,適用(yong)(yong)于(yu)現場(chang)(chang)工(gong)(gong)(gong)期緊,施工(gong)(gong)(gong)條件、用(yong)(yong)電(dian)量受制約,網(wang)(wang)(wang)架(jia)(jia)(jia)(jia)形(xing)(xing)狀復(fu)雜、桿件定(ding)(ding)位困難(nan)的(de)異形(xing)(xing)結(jie)(jie)(jie)構(gou)。螺(luo)栓(shuan)球(qiu)(qiu)(qiu)節(jie)(jie)點球(qiu)(qiu)(qiu)形(xing)(xing)網(wang)(wang)(wang)架(jia)(jia)(jia)(jia)系統(tong)基本(ben)由桿件、螺(luo)栓(shuan)球(qiu)(qiu)(qiu)、支撐支座(zuo)等(deng)組成。按(an)照節(jie)(jie)點形(xing)(xing)式可分為(wei)交叉桁架(jia)(jia)(jia)(jia)體系、四角錐體系、三(san)角錐體系等(deng)。支撐方式多為(wei)固(gu)定(ding)(ding)支座(zuo)支撐。對于(yu)大面積、大跨度(du)及有特殊受力(li)或伸縮(suo)要求(qiu)的(de)網(wang)(wang)(wang)架(jia)(jia)(jia)(jia)結(jie)(jie)(jie)構(gou)可采(cai)用(yong)(yong)橡膠支座(zuo)、滑移支座(zuo)、球(qiu)(qiu)(qiu)鉸支座(zuo)等(deng)支撐形(xing)(xing)式,以滿足(zu)結(jie)(jie)(jie)構(gou)自(zi)身的(de)受力(li)穩定(ding)(ding)、均衡,便于(yu)內(nei)力(li)釋放等(deng)設計要求(qiu)。
