3-按照結(jié)構(gòu)分類: 預應力鋼絞線根據(jù)鋼絲根數(shù)可分為7絲、2絲、3絲和19絲，較常用的是7絲結(jié)構(gòu)。</p><p style="text-indent:25px">冷拔鋼絲：六十年代前后，我國研制成功冷拔低碳鋼絲預應力成套技術(shù)，生產(chǎn)預制預應力空心樓板，由于冷拔絲費用低廉、工藝簡單，預應力空心樓板在全國得到普遍應用。中強預應力筋：七十年代初期至八十年代中期，我國相繼開發(fā)出熱軋低合金預應力鋼筋、熱處理預應力鋼筋和精軋螺紋預應力鋼筋，進一步促進了我國預應力技術(shù)的發(fā)展。其他： **預應力鋼絲、鋼絞線技術(shù) 八十年代以后，我國相繼從國外引進了十多條低松弛、**度預應力鋼絲、鋼絞線生產(chǎn)線，生產(chǎn)能力己達到年產(chǎn)量三十萬噸，這一技術(shù)的引進極大地促進了我國預應力工程技術(shù)的發(fā)展。鋼絞線預應力張拉施工設(shè)計控制張拉力，是指預應力張拉完成后鋼絞線在錨夾具前的拉力。</p><div

style="text-indent:25px">體外預應力鋼束*在錨固和轉(zhuǎn)向位置處，才能與結(jié)構(gòu)的豎向位移相協(xié)調(diào)，豎向約束點越少，結(jié)構(gòu)變形時體外預應力鋼束偏離原位置就越多，這就是體外預應力鋼束的二次效應。二次效應是體外預應力結(jié)構(gòu)在彈性階段區(qū)別于體內(nèi)預應力結(jié)構(gòu)的特征之一。由于二次效應考慮的是體外預應力鋼束與結(jié)構(gòu)豎向變形的差異，故這種效應是非線性的，對二次效應的研究必須考慮結(jié)構(gòu)的非線性影響。體外預應力在有限元計算中的實現(xiàn) 體外預應力的有限元計算主要有兩種方法： 1、以等效荷載的形式添加體外預應力； 2、單獨建立體外束單元的方式實現(xiàn)。模拔的預應力鋼絞線在絞合后經(jīng)過一次模具壓縮過程，結(jié)構(gòu)更加密實，表層更加適合錨具抓握。怎么找預應力鋼絞線下料長度</p><p

1、它包括整繩試驗和拆股試驗，其試樣均在捻制好的橋梁用鋼絞線中截??； 3、拆股試驗：是對橋梁用鋼絞線中的單根鋼絲分別進行拉力、反復彎曲、360度扭轉(zhuǎn)試驗； 2、整繩破斷拉力試驗：是在拉力試驗機長上進行的，在試樣兩端根據(jù)規(guī)格的不同用不同夾具固定，使夾具能牢牢夾住試樣，再將力平均施加到試樣各股上即可。 4、上述試驗均依照相應國家尺度進行，試驗結(jié)果應符合橋梁用鋼絞線尺度劃定的指標。哪有預應力鋼絞線多少錢</p><p
