**度螺栓是用特制的扳手上緊螺帽，使螺栓產(chǎn)生巨大而又受控制的預(yù)拉力，通過螺帽和墊板，對被連接件也產(chǎn)生了同樣大小的預(yù)壓力。在預(yù)壓力作用下，沿被連接件表面就會產(chǎn)生較大的摩擦力，顯然，只要軸力小于此摩擦力，構(gòu)件便不會滑移，連接就不會受到破壞，這就是**度螺栓連接的原理。 **度螺栓連接是靠連接件接觸面間的摩擦力來阻止其相互滑移的，為使接觸面有足夠的摩擦力，就必須提高構(gòu)件的夾緊力和增大構(gòu)件接觸面的摩擦系數(shù)。地腳螺栓的總長度可以通過以下公式來確定：L = 15d4ts。沉頭螺栓代理商</p><p style="text-indent:25px">**度螺栓實際上有摩擦型和承壓型兩種。沉頭螺栓代理商</p><p
