H型鋼(gang) 熱(re)軋H型鋼(gang)庫存(cun) Q345BH型鋼(gang)現(xian)貨

H型(xing)鋼(gang)(gang)是(shi)一種截面(mian)(mian)面(mian)(mian)積分配更(geng)加優化(hua)、強重比更(geng)加合理(li)的經濟斷面(mian)(mian)高效型(xing)材，因其斷面(mian)(mian)與英文字(zi)母“H”相同而得名(ming)。由于H型(xing)鋼(gang)(gang)的各(ge)個(ge)部位均以直角排布(bu)，因此H型(xing)鋼(gang)(gang)在各(ge)個(ge)方(fang)向上都具(ju)有抗彎能力強、施工簡(jian)單(dan)、節約成本和結構(gou)重量(liang)輕等優點，已被廣泛(fan)應(ying)用。

H型鋼(gang)(gang)的(de)(de)翼(yi)緣(yuan)內外側平(ping)行(xing)或(huo)接(jie)近于(yu)平(ping)行(xing)，翼(yi)緣(yuan)端部呈直(zhi)角，因(yin)(yin)此而得名平(ping)行(xing)翼(yi)緣(yuan)工(gong)(gong)字(zi)(zi)(zi)鋼(gang)(gang)。H型鋼(gang)(gang)的(de)(de)腹板(ban)(ban)(ban)厚度(du)(du)比腹板(ban)(ban)(ban)同(tong)(tong)樣高的(de)(de)普(pu)通(tong)工(gong)(gong)字(zi)(zi)(zi)鋼(gang)(gang)小，翼(yi)緣(yuan)寬度(du)(du)比腹板(ban)(ban)(ban)同(tong)(tong)樣高的(de)(de)普(pu)通(tong)工(gong)(gong)字(zi)(zi)(zi)鋼(gang)(gang)大(da)，因(yin)(yin)此又得名寬緣(yuan)工(gong)(gong)字(zi)(zi)(zi)鋼(gang)(gang)。由形(xing)狀所決定，H型鋼(gang)(gang)的(de)(de)截面模數、慣性(xing)矩(ju)及相應的(de)(de)強度(du)(du)均明顯優于(yu)同(tong)(tong)樣單重的(de)(de)普(pu)通(tong)工(gong)(gong)字(zi)(zi)(zi)鋼(gang)(gang)。用在(zai)不同(tong)(tong)要求(qiu)的(de)(de)金(jin)屬(shu)(shu)結構中，不論是承受彎曲力(li)矩(ju)、壓力(li)負(fu)荷、偏心負(fu)荷都(dou)顯示出(chu)它的(de)(de)優越性(xing)能(neng)，可(ke)較普(pu)通(tong)工(gong)(gong)字(zi)(zi)(zi)鋼(gang)(gang)大(da)大(da)提高承載能(neng)力(li)，節(jie)(jie)約(yue)金(jin)屬(shu)(shu)10%～40%。H型鋼(gang)(gang)的(de)(de)翼(yi)緣(yuan)寬、腹板(ban)(ban)(ban)薄、規格(ge)多、使(shi)用靈活，用于(yu)各種桁(heng)架(jia)結構中可(ke)節(jie)(jie)約(yue)金(jin)屬(shu)(shu)15%～20%。由于(yu)其翼(yi)緣(yuan)內外側平(ping)行(xing)，緣(yuan)端呈直(zhi)角，便于(yu)拼裝組合成各種構件，從而可(ke)節(jie)(jie)約(yue)焊接(jie)、鉚接(jie)工(gong)(gong)作(zuo)量25%左(zuo)右，能(neng)大(da)大(da)加快工(gong)(gong)程的(de)(de)建設速度(du)(du)，縮短工(gong)(gong)期(qi)。

由于具有上述優點，H型(xing)鋼應(ying)用廣泛，主要用于：各(ge)種民用和(he)工(gong)業建(jian)筑(zhu)結構;各(ge)種大(da)(da)(da)跨度的工(gong)業廠(chang)房(fang)和(he)現(xian)代化(hua)高層(ceng)建(jian)筑(zhu)，尤(you)其是地震活動頻繁地區和(he)高溫工(gong)作條件(jian)下(xia)的工(gong)業廠(chang)房(fang);要求承載能力大(da)(da)(da)、截面穩定性好、跨度大(da)(da)(da)的大(da)(da)(da)型(xing)橋(qiao)梁;重型(xing)設(she)備;高速公路;艦船骨架;礦山支護;地基(ji)處理和(he)堤壩工(gong)程;各(ge)種機器構件(jian)。
