style="text-indent:25px">體內(nèi)預(yù)應(yīng)的介紹：在體內(nèi)有粘結(jié)預(yù)應(yīng)力結(jié)構(gòu)中，力筋位于混凝土結(jié)構(gòu)的內(nèi)部，與結(jié)構(gòu)完全粘結(jié)，在任意截面處都與結(jié)構(gòu)變形協(xié)調(diào)，因此力筋的應(yīng)力是與某個混凝土截面息息相關(guān)的。傳統(tǒng)上來說，體內(nèi)預(yù)應(yīng)力筋是不被看作一個單獨構(gòu)件的。而體外筋在混凝土體外，自然成為一個相對于組成結(jié)構(gòu)整體的單獨構(gòu)件，其較體內(nèi)筋要重要許多。所以在承受動力荷載的體外預(yù)應(yīng)力結(jié)構(gòu)設(shè)計中，必須考慮到體外筋與結(jié)構(gòu)是**振動的，應(yīng)防止二者共振，而且當(dāng)體外預(yù)應(yīng)力筋在動力荷載（如車輛等）作用下發(fā)生共振時，就易發(fā)生錨具的疲勞破壞和轉(zhuǎn)向構(gòu)件處的預(yù)應(yīng)力筋的彎折疲勞破壞。在地震區(qū)時設(shè)計還必須考慮采取相應(yīng)措施，提高體外預(yù)應(yīng)力結(jié)構(gòu)的抗震性能。為某橋體外預(yù)應(yīng)力的布置形式。</p><p style="text-indent:25px">錨具的注意事項：預(yù)應(yīng)力筋的切割，宜采用砂輪鋸，不得采用電弧切割。鋼絞線編束時，應(yīng)逐根理順，捆扎成束，不得紊亂。鋼絞線固定端的擠壓型錨具或壓花型錨具，應(yīng)事先與承壓板和螺旋筋進(jìn)行組裝。施加預(yù)應(yīng)力用的機(jī)具設(shè)備及儀表，應(yīng)定期維護(hù)和標(biāo)定。預(yù)應(yīng)力筋張拉前，應(yīng)提供混凝土強(qiáng)度試壓報告。當(dāng)混凝土的抗壓強(qiáng)度滿足設(shè)計要求，且不低于設(shè)計強(qiáng)度等級的75%后，方可施加預(yù)應(yīng)力。預(yù)應(yīng)力筋張拉前，應(yīng)清理承壓板面，并檢查承壓板后面的混凝土質(zhì)量。如該處混凝土有空洞現(xiàn)象，應(yīng)在張拉前用環(huán)氧砂漿修補(bǔ)。預(yù)應(yīng)力錨具筋應(yīng)平順，不得有彎折。</p><div

style="text-indent:25px">注意事項：大噸位預(yù)應(yīng)力筋正式張拉前，應(yīng)會同專業(yè)人員進(jìn)行試張拉。確認(rèn)張拉工藝合理，張拉伸長值正常，并無有害裂縫出現(xiàn)后，方可成批張拉。必要時測定實際的孔道磨擦損失。對曲線預(yù)應(yīng)力束不得采用小型千斤頂單根張拉;以免造成不必要的預(yù)應(yīng)力損失。在張拉時，操作人員必須站在安全地帶，做好防護(hù)措施，注意操作人員嚴(yán)禁站在張拉時和張拉好的預(yù)應(yīng)力筋前端;如該處混凝土有空洞現(xiàn)象，應(yīng)在張拉前用環(huán)氧砂漿修補(bǔ);錨具安裝時，錨板應(yīng)對正，夾片應(yīng)打緊，且片位要均勻:但打緊夾片時不得過重敲打，以免把夾片敲壞。經(jīng)過幾次錨具施工安裝擴(kuò)大成為圓球的形狀，后裝入藥物進(jìn)行錨具施工安裝。好用的預(yù)應(yīng)力扁錨具</p><p

style="text-indent:25px">錨具在應(yīng)用時一定要做好以上保管工作，只有這樣才能有效延長其使用壽命，為我們節(jié)約工程成本，提高工作效益。預(yù)應(yīng)力錨具適用于工程建設(shè)過程中，是混凝土預(yù)應(yīng)力張拉用的錨具。一般在橋梁施工中經(jīng)常用到，預(yù)先安裝好定位然后澆筑混凝土，埋在混凝土的兩端，也就是波紋管的兩個端頭，是為了張拉時千斤頂?shù)姆€(wěn)定作用而設(shè)置的端面?；炷辽纤玫挠肋h(yuǎn)性錨固裝置。預(yù)應(yīng)力錨具常見的可分為2類，張拉端錨具安裝在預(yù)應(yīng)力筋端部且可以張錨具也稱之為預(yù)應(yīng)力錨具，所謂錨具是在后張法結(jié)構(gòu)或構(gòu)件中，為保持預(yù)應(yīng)力筋的拉力并將其傳遞到混拉的錨具；固定端錨具安裝在預(yù)應(yīng)力筋端部，通常埋入混凝土中且不用以張拉的錨具。好用的預(yù)應(yīng)力扁錨具</p></p><br
