style="text-indent:25px">槽鋼在使用之前，需要注意的事項(xiàng);1、槽鋼樁起吊-----槽鋼就位-----挖機(jī)靜壓-----經(jīng)緯儀校正垂直度-----靜壓至施工標(biāo)高-----支撐安裝。 2.槽鋼樁起吊時(shí)采用φ14鋼絲繩作為吊索，鋼板樁起吊時(shí)必須注意防止吊鉤松動(dòng)脫落。樁頭起吊至50cm時(shí)，應(yīng)檢查吊鉤的現(xiàn)狀，然后才允許起吊。起吊過(guò)程應(yīng)緩慢、穩(wěn)定，不允許突然轉(zhuǎn)向及鋼板樁吊離地面后大幅度轉(zhuǎn)向。3.槽鋼樁吊至打樁位置后，進(jìn)行樁位的調(diào)整，調(diào)整結(jié)束后，挖機(jī)開(kāi)始進(jìn)行靜壓。4.槽鋼樁壓下1m后，用經(jīng)緯儀進(jìn)行垂直度的測(cè)量并調(diào)整，校正后再開(kāi)始靜壓，直至施工標(biāo)高。5.槽鋼樁打至轉(zhuǎn)角位置時(shí)，應(yīng)在轉(zhuǎn)角處增加增強(qiáng)鋼板樁。6、支撐安裝：首先進(jìn)行挖土，將土體挖到鋼板樁頂下1米，土方全部外運(yùn)，做到角部不余任何松土和其它障礙物，支撐采用雙拼100×100型鋼，圍檁采用28b槽鋼，按支撐標(biāo)高，在鋼板樁上焊接。安放鋼圍檁，檢查支撐安裝焊接每個(gè)焊縫節(jié)點(diǎn)符合要求后，方可開(kāi)挖土方，挖土必須做到先撐后挖原則，整個(gè)鋼支撐施工時(shí)間１天左右。</p><p style="text-indent:25px">槽鋼分普通槽鋼和輕型槽鋼。熱軋普通槽鋼的規(guī)格為5-40#。經(jīng)供需雙方協(xié)議供應(yīng)的熱軋變通槽鋼規(guī)格為6.5-30#。槽鋼主要用于建筑結(jié)構(gòu)、車(chē)輛制造、其它工業(yè)結(jié)構(gòu)和固定盤(pán)柜等，槽鋼還常常和工字鋼配合使用。槽鋼層一般是在第七至八層腳手架設(shè)置一層槽鋼。槽鋼層就是很多槽鋼搭建出來(lái)的，槽鋼是截面為凹槽形的長(zhǎng)條鋼材。其規(guī)格表示方法，如120*53*5，表示腰高為120毫米，腿寬為53毫米的槽鋼，腰厚為5毫米的槽鋼，或稱(chēng)12#槽鋼。總的來(lái)說(shuō)，現(xiàn)在的房屋的槽鋼層伸出的槽鋼都會(huì)處理得非常好的。防腐處理及包裹的相當(dāng)嚴(yán)實(shí)，不會(huì)出現(xiàn)以前的腐蝕的問(wèn)題。槽鋼是截面為凹槽形的長(zhǎng)條狀鋼材。</p><div

style="text-indent:25px">槽鋼剪刃設(shè)計(jì)的基本依據(jù)是槽鋼成品孔型形狀，這種設(shè)計(jì)在剪切過(guò)程中易出現(xiàn)以下問(wèn)題：一是槽鋼兩肩部與其他部分相比，相對(duì)較厚，所需剪切力也較大，剪刃磨損較快，剪刃使用一段時(shí)間后。這一部分相對(duì)磨損量大，致使肩部間隙較大，易出現(xiàn)塌肩現(xiàn)象；二是槽鋼兩腿與腰部處相比，由于剪切角度的影響，當(dāng)剪刃磨損后，在剪切兩腿時(shí)，剪切量變小，腿部剪切由通常的剪斷變成了撕斷，槽鋼腿端面極易出現(xiàn)毛刺；三是上、下剪刃腿部斜度與槽鋼成品孔型基本一致，這樣在剪切時(shí)腿部基本同時(shí)受力，剪切力較大，剪刃磨損較快，一方面腿端剪切壓痕嚴(yán)重，另一方面剪刃老化后，極易出現(xiàn)槽鋼剪切部分撕裂、毛刺較多的現(xiàn)象。后兩點(diǎn)是影響槽鋼剪切質(zhì)量的主要原因。依照鋼結(jié)構(gòu)的理論來(lái)說(shuō)，應(yīng)該是槽鋼翼板受力，就是說(shuō)槽鋼應(yīng)該立著，而不是趴著。貨架槽鋼企業(yè)</p><p style="text-indent:25px">槽鋼按形狀又可分為4種：冷彎等邊槽鋼、冷彎不等邊槽鋼、冷彎內(nèi)卷邊槽鋼、冷彎外卷邊槽鋼。貨架槽鋼企業(yè)</p><p style="text-indent:25px">在使用槽鋼搭建的時(shí)候，尺寸也有嚴(yán)格的要求，較好不要超過(guò)四米，較大也不要超過(guò)六米，這樣的槽鋼搭建出來(lái)的性能才是較穩(wěn)定的。之所以選用槽鋼進(jìn)行搭建，主要是因?yàn)樗俣缺容^快，可以快速投入使用。但是由于槽鋼的規(guī)格都比較小，在高負(fù)荷的情況下容易發(fā)出晃動(dòng)聲。槽鋼樓面板的較關(guān)鍵一點(diǎn)就是槽鋼兩端的固定。1.它由墻角鋼制成，并用膨脹螺絲固定在墻上。然后用槽鋼固定在墻上。也可采用植筋固定。這種方法只有于兩端墻為承重墻或梁經(jīng)過(guò)的地方。膨脹螺絲固定在墻上，膨脹螺絲間距不大于200mm。2.第2條。首先在墻體上打一個(gè)孔，然后將槽鋼插入墻體，槽鋼的重量直接由墻體承擔(dān)。這種方法只有于承重墻或較厚的剪力墻。另一種方法是直接安裝另一個(gè)槽鋼來(lái)支撐橫向槽鋼。垂直槽鋼應(yīng)固定在墻上。該方法應(yīng)考慮垂直槽鋼所在樓層的承載力。建議采用多點(diǎn)分布式支撐，而不是集中在少數(shù)槽鋼上。貨架槽鋼企業(yè)</p></p><br
