id="oz598ri" class="box"><p><p> 鋼結(jié)構(gòu)連接用以螺栓性能等級分3.6、4.6、4.8、5.6、6.8、8.8、9.8、10.9、12.9等10余個等級， </p> <p> <br /> </p> <p> 普通螺栓連接中,螺栓與孔間有間隙.其優(yōu)點(diǎn)是加工方便,成本低,所以應(yīng)用范圍廣. </p> <p> 鉸制孔用螺栓中,其螺桿外徑與螺栓孔(由高精度鉸刀加工而成)的內(nèi)徑具有同一基本尺寸,并常采用過渡配合.它適用于承受垂直與螺栓軸線的橫向載荷. </p> <p> <br /> </p> <p> 普通螺栓連接的構(gòu)造要求： </p> <p> (1)螺栓的直徑 </p> <p> 在同一結(jié)構(gòu)連接中，無論是臨時安裝螺栓還是長久螺栓，為了便于制造，柳州處理螺栓，宜用同一種直徑的螺栓孔d。螺栓直徑d的選擇根據(jù)連接件的尺寸和受力大小而定，可參照表9-1螺栓的有效面積，按螺栓結(jié)構(gòu)形式和受力大小進(jìn)行計(jì)算，柳州處理螺栓。常用的標(biāo)準(zhǔn)螺栓直徑是M16、M18、M20、M22、M24，柳州處理螺栓。 </p> <p> (2)螺栓的排列及間距 </p> <p> 螺栓的排列及間距可分為并列排列與錯位排列兩種，如圖9-2所示。其排列原則如下： </p> <p> 受力要求螺栓孔(do)的小端距(沿受力方向)為2do，以免板端被剪掉；螺栓孔的小邊距(垂直于受力方向)為1．5Jo(切割邊)或1．2do(軋成邊)。在型鋼上，螺栓應(yīng)排列在型鋼準(zhǔn)線上。中間螺孔的小間距(栓距和線距)為3do，否則螺孔周圍應(yīng)力集中的相互影響較大，且對鋼板的截面削弱過多，從而降低其承載能力。 </p> <p> <br />

螺栓的表示方法是直徑和長度。普通的粗牙螺紋是這樣標(biāo)注的M8*15.細(xì)牙是M8*15*1.也就是要把回螺距也標(biāo)注上去。答粗牙是不標(biāo)螺距的，細(xì)牙才標(biāo)。 </p> <p> 螺栓：由頭部和螺桿（帶有外螺紋的圓柱體）兩部分組成的一類緊固件，螺栓需與螺母配合，用于緊固連接兩個帶有通孔的零件。這種連接形式稱螺栓連接。如把螺母從螺栓上旋下，又可以使這兩個零件分開，所以螺栓連接是屬于可拆卸連接。其中六角頭是常用的，一般沉頭用在要求連接的地方。 </p> <p> <br /> 柳州處理螺栓螺栓的等級都有什么含義？</p><div

六角頭螺栓分外六角螺栓和內(nèi)六角螺栓，是常用的緊固件，主要用作機(jī)械設(shè)備的緊固。無論是外六角還是內(nèi)六角，它們的規(guī)格尺寸表示方法都是類似的。外六角螺栓國家標(biāo)準(zhǔn)GB/T5782-86，這個標(biāo)準(zhǔn)規(guī)定了螺紋規(guī)格為M3~M64，A和B級的六角頭螺栓，A級用于D<=24和L<=10D或L。 </p> <p> <br /> </p> <p> 六角頭螺栓產(chǎn)品等級分為A、B、C三級，表示精度，其中A級精確，C級精度差。精度不同，作用的地方也不同，A級比B級高，要求高的地方用A級，大多數(shù)都選用B級。A級用于承載較大，要求精度高或受沖擊、振動載荷的場合。 </p> <p> <br /> </p><p> 安裝螺栓僅僅是在預(yù)組裝是為了組裝方便使用的長久螺栓則是安裝連接之后不再拆除的。一般安裝螺栓使用普通螺栓。 </p> <p> <br /> </p> <p> 長久的螺栓則要根據(jù)圖紙要求使用相應(yīng)的級別在有些時候安裝螺栓和長久螺栓相同級別沒有損壞的情況下可以直接使用 </p> <p> <br /> </p> <p> 螺栓使用過程中的注意事項(xiàng)： </p> <p> <br /> </p> <p> (1)表面浮銹、油污、螺栓孔壁有毛刺、焊瘤等均需處理干凈。 </p> <p> <br /> </p> <p> (2)接觸摩擦面處理后要達(dá)到規(guī)定的抗劃移系數(shù)要求。使用的高壓螺栓應(yīng)有配套的螺母、墊圈，使用時按配套使用,不得互換。 </p> <p> <br /> </p> <p> (3)處理好的構(gòu)件摩擦面安裝時不允許沾油污、泥土等雜物。 </p> <p> <br /> </p> <p> (4)安裝時組件摩擦面應(yīng)保持干燥,不可沾水。 </p> <p> <br /> </p> <p> (5)在安裝前嚴(yán)格檢查并校正連接的鋼板的變形。 </p> <p> <br /> </p> <p> (6)安裝時禁止錘擊打入螺栓以防止螺栓絲扣受損。 </p> <p> <br /> </p> <p> (7)使用時定期檢測的保證扭矩的準(zhǔn)確度,并按正確的扭緊順序操作。 </p> <p> <br /> 螺栓使用過程中的注意事項(xiàng)有哪些？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

1、一次埋入法：澆灌混凝土?xí)r，將地腳螺栓埋入。當(dāng)高塔等以傾覆控制時，地腳螺栓宜采用一次埋入法。 </p> <p> 2、預(yù)留孔法：設(shè)備就位，將孔洞打掃干凈，將地腳螺栓放入孔中，設(shè)備定位找正后再用比原基礎(chǔ)高一級的無收縮細(xì)石混凝土進(jìn)行澆灌，搗固密實(shí)。一次埋入之地腳螺栓中心至基礎(chǔ)邊緣的距離不應(yīng)小于2d（d為地腳螺栓直徑），且不應(yīng)小于15mm（d≤20時不應(yīng)小于10mm），并不小于錨板寬度的一半加50mm，當(dāng)不能滿足上述要求時，應(yīng)采取適當(dāng)措施，予以加強(qiáng)。結(jié)構(gòu)用的地腳螺栓直徑不宜小于20mm。當(dāng)承受地震作用時，應(yīng)采用雙螺母固定，或采用其它有效防止松動的措施，但地腳螺栓的錨固長度應(yīng)比非地震作用的錨固長度增加5d。 </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(yīng)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，待混凝土凝固到設(shè)計(jì)強(qiáng)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拔出來處理。如螺栓過長，可在機(jī)床上切去一段再套螺紋。

**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)。構(gòu)件間的夾緊力是靠對螺栓施加預(yù)拉力來實(shí)現(xiàn)的，所以螺栓必須采用**度鋼制造，這也就是稱為**度螺栓連接的原因。 </p> <p> **度螺栓連接中，摩擦系數(shù)的大小對承載力的影響很大。試驗(yàn)表明，摩擦系數(shù)主要受接觸面的形式和構(gòu)件的材質(zhì)影響。為了增大接觸面的摩擦系數(shù)，施工時常采用應(yīng)噴砂、用鋼絲刷清理等方法對連接范圍內(nèi)構(gòu)件接觸面進(jìn)行處理。 </p> <p> <br /> 柳州處理螺栓</p><p
