鋼筋連接套筒長度影響著什么?鋼筋套筒長度的絕對性作用,下面咸陽龍超機械小編來(lai)給(gei)你說說。
鋼筋(jin)(jin)(jin)連(lian)接(jie)(jie)套筒(tong)(tong)(tong)(tong)的長(chang)度(du)(du)是決定(ding)鋼筋(jin)(jin)(jin)連(lian)接(jie)(jie)套筒(tong)(tong)(tong)(tong)合格的重(zhong)要因素,關(guan)(guan)于鋼筋(jin)(jin)(jin)連(lian)接(jie)(jie)套筒(tong)(tong)(tong)(tong)長(chang)度(du)(du),國家有(you)關(guan)(guan)部委都沒有(you)給(gei)出具體標準(zhun),中(zhong)華人民共和國住房和城鄉建(jian)設(she)部發布(bu)的《鋼筋(jin)(jin)(jin)機械連(lian)接(jie)(jie)技術規(gui)程》(JGJ107-2010)中(zhong),也沒有(you)明確規(gui)定(ding)鋼筋(jin)(jin)(jin)連(lian)接(jie)(jie)套筒(tong)(tong)(tong)(tong)的長(chang)度(du)(du)。本是一(yi)家專業生產鋼筋(jin)(jin)(jin)直螺紋連(lian)接(jie)(jie)套筒(tong)(tong)(tong)(tong)的大型生產企(qi)業,該公司生產的鋼筋(jin)(jin)(jin)連(lian)接(jie)(jie)套筒(tong)(tong)(tong)(tong)的長(chang)度(du)(du)是:16:40mm 18:45mm 20:50mm 22:55 mm 25:60mm 28: 70mm 32:75mm ,所用產品(pin)均符合單項拉(la)伸試驗(yan),高應力反復(fu)拉(la)壓實驗(yan),大變(bian)形(xing)反復(fu)拉(la)壓試驗(yan)所檢(jian)驗(yan)的項目。
鋼筋連接套筒試件怎么做?
做法標準:
1、鋼筋下料(liao)采(cai)用無(wu)齒鋸切割,端(duan)面(mian)平直(zhi);
2、鋼筋(jin)套筒合格,鋼筋(jin)螺(luo)(luo)紋加工牙形(xing)飽滿,無斷(duan)牙禿(tu)牙等缺(que)陷;螺(luo)(luo)紋加工完畢,應套保護蓋保護;
3、套筒連接采用扭(niu)矩扳手連接,擰(ning)緊力矩值符合規范要求;
4、逐一檢查,合格后點油漆(qi)標明。
質量標準:
1、鋼筋端頭應與(yu)軸線垂直,不得有馬蹄形或撓曲;
2、扭矩(ju)扳手擰緊力矩(ju)值符合規(gui)范或設(she)計要求(qiu),力矩(ju)扳手的精(jing)度為(wei)±15%;
3、連接后每端外(wai)露不能超過一個完整絲(si);
4、兩條(tiao)互相連接的鋼筋肋部應在一條(tiao)直線(xian)上(shang)。
