鋼筋直螺紋套筒的技術特點

1、連接強度高，連接質量穩定可靠

接頭(tou)強度(du)(du)(du)達到行(xing)業標(biao)準JGJ107-2010《鋼筋(jin)(jin)機械連(lian)接通(tong)(tong)用技術規(gui)程(cheng)》中Ⅰ級(ji)接頭(tou)性能的(de)要求。接頭(tou)抗拉(la)強度(du)(du)(du)不小于被連(lian)接鋼筋(jin)(jin)實際抗拉(la)強度(du)(du)(du)或鋼筋(jin)(jin)抗拉(la)強度(du)(du)(du)標(biao)準的(de)1.10倍。抗疲勞性能好。接頭(tou)通(tong)(tong)過行(xing)業標(biao)準規(gui)定的(de)二(er)百萬(wan)次(ci)疲勞強度(du)(du)(du)試驗。節省材料。以(yi)直徑40mm鋼筋(jin)(jin)連(lian)接套(tao)筒(tong)為例(li)，擠(ji)壓(ya)套(tao)筒(tong)質量4kg，直螺紋(wen)套(tao)筒(tong)1.1 kg。直螺紋(wen)套(tao)筒(tong)質量是擠(ji)壓(ya)套(tao)筒(tong)的(de)25%，而接頭(tou)性能卻能與擠(ji)壓(ya)接頭(tou)媲美。

2、施工方便、連接速度快

鋼(gang)筋(jin)(jin)(jin)絲頭加工(gong)(gong)工(gong)(gong)廠化作業，不(bu)占用(yong)(yong)(yong)施工(gong)(gong)工(gong)(gong)期。現(xian)場連(lian)(lian)接(jie)裝(zhuang)配作業，占用(yong)(yong)(yong)時間短。鋼(gang)筋(jin)(jin)(jin)絲頭加工(gong)(gong)簡(jian)單。鋼(gang)筋(jin)(jin)(jin)一次裝(zhuang)卡即可完成剝肋、滾(gun)壓螺(luo)紋兩道(dao)工(gong)(gong)序，加工(gong)(gong)速度(du)快，成型螺(luo)紋精度(du)高。適用(yong)(yong)(yong)范圍廣。對鋼(gang)筋(jin)(jin)(jin)無(wu)可焊性要(yao)求，適用(yong)(yong)(yong)于直徑14~50mmHRB335、HRB400鋼(gang)筋(jin)(jin)(jin)在任(ren)意方位的同(tong)、異(yi)徑連(lian)(lian)接(jie)。

3、環保施工

鋼筋絲(si)頭(tou)加工(gong)及接頭(tou)現(xian)場施(shi)工(gong)無(wu)(wu)噪(zao)音污染、無(wu)(wu)明火、無(wu)(wu)煙塵(chen)，安全可靠。節約能源。設(she)備功(gong)率僅為3~4kw，不(bu)需專用(yong)(yong)配電(dian)(dian)設(she)施(shi)，不(bu)需架(jia)設(she)專用(yong)(yong)電(dian)(dian)線。抗低溫(wen)性能好。通過-400C低溫(wen)試驗。全天候(hou)施(shi)工(gong)。不(bu)受風、雨、雪等氣候(hou)條件的影響。

鋼筋直螺紋套筒連接規范

1、連(lian)接(jie)鋼筋時(shi)，鋼筋規(gui)格(ge)和套筒(tong)的(de)規(gui)格(ge)必須一致，鋼筋和套筒(tong)的(de)絲扣應干凈、完好無損。

2、采(cai)用預埋接(jie)頭時，連(lian)(lian)接(jie)套筒(tong)的位置(zhi)、規(gui)格和(he)數量應(ying)符(fu)合設計要求。帶(dai)連(lian)(lian)接(jie)套筒(tong)的鋼筋應(ying)固定牢，連(lian)(lian)接(jie)套筒(tong)的外露端應(ying)有(you)保護蓋。

3、滾壓直螺紋接頭應(ying)(ying)使(shi)用管鉗和力矩扳(ban)手(shou)進(jin)行施(shi)工(gong)，將兩(liang)個(ge)鋼筋絲頭在套筒中(zhong)間位(wei)置相互頂緊(jin)，接頭擰緊(jin)力矩應(ying)(ying)符合表(biao)4的(de)規定(ding)。力矩扳(ban)手(shou)的(de)精度為±5％。
