預緊力的大小，除了受限于螺釘材料的強度外，還受限于被聯(lián)接件的材料強度。當內(nèi)外螺紋的材料相同時，只校核外螺紋強度即可。對于旋合長度較短、非標準螺紋零件構(gòu)成的聯(lián)接、內(nèi)外螺紋材料的強度相差較大的受軸向載荷的螺紋聯(lián)接，還應校核螺紋牙的強度。 </p> <p> <br /> </p> <p>

地腳螺栓的安裝規(guī)劃地腳螺栓在基礎(chǔ)內(nèi)松動的處理在近擰緊地腳螺栓時，可能將螺栓拔活，此時應先螺栓調(diào)整至原位置，并將螺栓周圍的基礎(chǔ)鏟出足夠的位置，然后在螺栓上焊縱橫兩個U形鋼筋，之后用水將坑內(nèi)清洗干凈并灌漿。 </p> <p> <br /> </p> <p> 待混凝土凝固到設(shè)計強度后再擰緊活地腳螺栓偏差的處理活地腳螺栓偏差的處理方法，大致與死地腳螺栓的方法相同，只是可以將地腳螺栓**處理。如螺栓過長，可在機床上切去一段再套螺紋；如螺栓過短，可用熱鍛法伸長；如位置不符，用彎曲法矯正。 </p> <p> <br /> </p> <p> 應用行業(yè)：適用于各種設(shè)備固定、鋼結(jié)構(gòu)基礎(chǔ)預埋件、路燈、交通指示牌、泵、鍋爐安裝、重型設(shè)備預埋固定等。 </p> <p> <br /> </p><p> **度螺栓摩擦型和承壓型連接的區(qū)別： </p> <p> **螺栓連接是通過螺栓桿內(nèi)很大的擰緊預拉力把連接板的板件夾緊，足以產(chǎn)生很大的摩擦力，從而提高連接的整體性和剛度，當受剪力時，按照設(shè)計和受力要求的不同，可分為**螺栓摩擦型連接和**螺栓承壓型連接兩種，兩者的本質(zhì)區(qū)別是極限狀態(tài)不同，雖然是同一種螺栓，但是在計算方法、要求、適用范圍等方面都有很大的不同。在抗剪設(shè)計時，**螺栓摩擦型連接是以外剪力達到板件接觸面間由螺栓擰緊力所提供的可能大摩擦力作為極限狀態(tài)，也即是保證連接在整個使用期間內(nèi)外剪力不超過大摩擦力。板件不會發(fā)生相對滑移變形（螺桿和孔壁之間始終保持原有的空隙量），被連接板件按彈性整體受力。在抗剪設(shè)計時，**螺栓承壓型連接中允許外剪力超過大摩擦力，這時被連接板件之間發(fā)生相對滑移變形，直到螺栓桿與孔壁接觸，此后連接就靠螺栓桿身剪切和孔壁承壓以及板件接觸面間的摩擦力共同傳力，以桿身剪切或孔壁承壓破壞作為連接受剪的極限狀態(tài)。化學螺栓和膨脹螺栓又什么區(qū)別？</p><div

style="text-indent:25px">普通螺栓按照制作精度可分為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)成本低，多用于抗拉連接或安裝時的臨時固定。螺栓連接中的預緊力指什么？駐馬店工業(yè)螺栓</p><p
