style="text-indent:25px">普通的螺栓按照制作精度可以分為A、B、C三個等級，A、B級為精制螺栓，C級為粗制螺栓。對于鋼結(jié)構(gòu)用連接螺栓，除特別注明外，一般為普通粗制C級螺栓。不同的級次加工的方法存在差異，通常對應(yīng)加工方式如下：①A、B級螺栓的栓桿由車床加工而成，表面光滑，尺寸精確，其材料性能等級為8.8級，制作安裝復(fù)雜，價格較高，很少采用;②C級螺栓用未加工的圓鋼制成，尺寸不夠精確，其材料性能等級為4.6級或4.8級?？辜暨B接時變形大，但安裝方便，生產(chǎn)成本是比較低的，多用于抗拉連接或安裝時的臨時固定。</p><p style="text-indent:25px">**度的螺栓施加預(yù)拉力和靠摩擦力傳遞外力。普通螺栓連接靠栓桿抗剪和孔壁承壓來傳遞剪力，擰緊螺帽時產(chǎn)生預(yù)拉力很小，其影響可以忽略不計(jì)，而**螺栓除了其材料強(qiáng)度很高之外，還給螺栓施加很大預(yù)拉力，使連接構(gòu)件間產(chǎn)生擠壓力，從而使垂直于螺桿方向有很大摩擦力，而且預(yù)拉力、抗滑移系數(shù)和鋼材種類都直接影響**螺栓的承載力。根據(jù)受力特點(diǎn)分承壓型和摩擦型.兩者計(jì)算方法不同。**螺栓較小規(guī)格M12，常用M16~M30，超大規(guī)格的螺栓性能不穩(wěn)定，設(shè)計(jì)中應(yīng)慎重使用。螺栓：M
