內蒙古(gu)輕(qing)鋼(gang)(gang)別墅(shu)廠家告訴您(nin)鋼(gang)(gang)結(jie)構的連接方法(fa)有焊接、普通螺栓連接、高強度螺栓連接。

1.焊接：施工(gong)(gong)(gong)單位采用(yong)的鋼尺、焊接材料、焊接方(fang)法(fa)等，應(ying)進(jin)行焊接工(gong)(gong)(gong)藝評定。焊工(gong)(gong)(gong)應(ying)經考(kao)試合格并取得資格證(zheng)書，應(ying)在認可范圍內焊接作(zuo)業，嚴禁無證(zheng)上崗(gang)。

焊接：鋼結構焊接缺陷通(tong)常分為：裂紋(wen)、空穴、固體夾雜、未熔合(he)、未焊透，形狀缺陷和上述以外的其他(ta)缺陷。其主要處理(li)方法為：

產出缺陷處焊縫金(jin)屬，進行補焊。

2.普通(tong)螺栓(shuan)連(lian)接制孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)可(ke)(ke)采(cai)(cai)(cai)(cai)用(yong)鉆(zhan)孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)，沖孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)，洗孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)，鉸孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)，等方(fang)法，對直徑較大或長(chang)形孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)也(ye)可(ke)(ke)采(cai)(cai)(cai)(cai)用(yong)氣割(ge)制孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)。嚴禁(jin)氣割(ge)擴孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)。鉆(zhan)孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)，沖孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)為一(yi)(yi)次制孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)(其中，沖孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)的(de)板厚應≤12mm)銑(xian)孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)，鉸孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)等為二次制孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)，即在一(yi)(yi)次制孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)的(de)基(ji)礎上(shang)進(jin)行孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)的(de)二次加工(gong)。采(cai)(cai)(cai)(cai)用(yong)氣割(ge)制孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)的(de)方(fang)法，實(shi)際加工(gong)時一(yi)(yi)般(ban)直徑在80mm以上(shang)的(de)圓孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)，鉆(zhan)孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)不能實(shi)現時可(ke)(ke)采(cai)(cai)(cai)(cai)用(yong)氣割(ge)制孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)，另外(wai)對于(yu)長(chang)園孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)或異(yi)形孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)一(yi)(yi)般(ban)可(ke)(ke)以采(cai)(cai)(cai)(cai)用(yong)先行鉆(zhan)孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)然后采(cai)(cai)(cai)(cai)用(yong)氣割(ge)制孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)的(de)方(fang)法。

3.高強螺栓(shuan)連(lian)接

高強度螺栓(shuan)按(an)連(lian)(lian)接(jie)(jie)形(xing)式通(tong)常分為(wei)摩(mo)擦(ca)(ca)連(lian)(lian)接(jie)(jie)、張拉連(lian)(lian)接(jie)(jie)和承壓連(lian)(lian)接(jie)(jie)等，其中摩(mo)擦(ca)(ca)連(lian)(lian)接(jie)(jie)時目(mu)前(qian)廣泛采用基本陜西鋼(gang)結構連(lian)(lian)接(jie)(jie)方式高強度螺栓(shuan)連(lian)(lian)接(jie)(jie)處摩(mo)擦(ca)(ca)面的處理方法(fa)通(tong)常有噴砂法(fa)，酸洗法(fa)，砂輪打磨法(fa)和鋼(gang)絲刷人(ren)工(gong)除銹。可根據設計抗滑移系數的要(yao)求選(xuan)擇處理工(gong)藝，抗滑移系數需(xu)滿足設計要(yao)求。
