止通規與(yu)塞規有(you)啥區別？大家俗稱的鋼筋連接通止規，是(shi)包含：塞規和(he)環規。

螺(luo)紋塞規(gui)(gui)：是(shi)測(ce)量內螺(luo)紋尺寸(cun)的(de)正確性的(de)工具。我們的(de)塞規(gui)(gui)是(shi)專門檢測(ce)鋼筋(jin)連接套(tao)筒接頭標準與否的(de)專用(yong)(yong)工具。根(gen)據各工地(di)所用(yong)(yong)套(tao)筒，牙型(xing)角有75度和(he)60度兩種，購(gou)買前請明確自己生產套(tao)筒的(de)牙型(xing)角和(he)螺(luo)距。螺(luo)紋塞規(gui)(gui)（栓規(gui)(gui)），同一個(ge)規(gui)(gui)格有兩端作為(wei)一套(tao)同時使(shi)用(yong)(yong)，分別是(shi)通(tong)規(gui)(gui)和(he)止規(gui)(gui)。1，用(yong)(yong)通(tong)規(gui)(gui)試擰(ning)，如(ru)果不(bu)能(neng)擰(ning)進就不(bu)合(he)格，此時就不(bu)必要用(yong)(yong)止規(gui)(gui)了，因為(wei)它已經是(shi)不(bu)良品了。2，用(yong)(yong)通(tong)規(gui)(gui)試擰(ning)，如(ru)果能(neng)夠擰(ning)進，再用(yong)(yong)止規(gui)(gui)擰(ning)，如(ru)果止規(gui)(gui)不(bu)能(neng)擰(ning)進或(huo)只擰(ning)進一兩個(ge)牙規(gui)(gui)那就是(shi)合(he)格。

螺(luo)(luo)(luo)紋(wen)(wen)(wen)(wen)(wen)(wen)(wen)環(huan)(huan)(huan)規(gui)(gui)：是(shi)(shi)測量外(wai)(wai)螺(luo)(luo)(luo)紋(wen)(wen)(wen)(wen)(wen)(wen)(wen)尺(chi)(chi)寸(cun)的(de)正(zheng)確性的(de)工(gong)(gong)具。我(wo)們的(de)環(huan)(huan)(huan)規(gui)(gui)是(shi)(shi)專(zhuan)門(men)檢(jian)測鋼筋連接絲頭(tou)標準與(yu)否(fou)(fou)的(de)專(zhuan)用工(gong)(gong)具。根據各工(gong)(gong)地所用套筒(tong)，牙(ya)型角有75度和(he)60度兩種(zhong)(zhong)，購(gou)買前請明(ming)確自己生產絲頭(tou)的(de)牙(ya)型角和(he)螺(luo)(luo)(luo)距。螺(luo)(luo)(luo)紋(wen)(wen)(wen)(wen)(wen)(wen)(wen)環(huan)(huan)(huan)規(gui)(gui)用途供檢(jian)查(cha)工(gong)(gong)件(jian)外(wai)(wai)螺(luo)(luo)(luo)紋(wen)(wen)(wen)(wen)(wen)(wen)(wen)尺(chi)(chi)寸(cun)是(shi)(shi)否(fou)(fou)合格(ge)(ge)(ge)用。每種(zhong)(zhong)規(gui)(gui)格(ge)(ge)(ge)規(gui)(gui)格(ge)(ge)(ge)螺(luo)(luo)(luo)紋(wen)(wen)(wen)(wen)(wen)(wen)(wen)環(huan)(huan)(huan)規(gui)(gui)又分為(wei)通(tong)(tong)(tong)規(gui)(gui)和(he)止(zhi)(zhi)規(gui)(gui)兩種(zhong)(zhong)，可(ke)分別(bie)單(dan)獨購(gou)買或一并(bing)購(gou)買（標注價格(ge)(ge)(ge)為(wei)一個型號一種(zhong)(zhong)通(tong)(tong)(tong)規(gui)(gui)或者(zhe)止(zhi)(zhi)規(gui)(gui)的(de)價格(ge)(ge)(ge)）。檢(jian)查(cha)時(shi)，只(zhi)有當通(tong)(tong)(tong)規(gui)(gui)能與(yu)工(gong)(gong)件(jian)外(wai)(wai)螺(luo)(luo)(luo)紋(wen)(wen)(wen)(wen)(wen)(wen)(wen)旋合通(tong)(tong)(tong)過，而止(zhi)(zhi)規(gui)(gui)只(zhi)與(yu)工(gong)(gong)件(jian)外(wai)(wai)螺(luo)(luo)(luo)紋(wen)(wen)(wen)(wen)(wen)(wen)(wen)部分旋合，且(qie)旋合量不超(chao)過兩個螺(luo)(luo)(luo)距時(shi)，可(ke)判(pan)定該外(wai)(wai)螺(luo)(luo)(luo)紋(wen)(wen)(wen)(wen)(wen)(wen)(wen)合格(ge)(ge)(ge)；除(chu)此之外(wai)(wai)可(ke)判(pan)定外(wai)(wai)螺(luo)(luo)(luo)紋(wen)(wen)(wen)(wen)(wen)(wen)(wen)尺(chi)(chi)寸(cun)不合格(ge)(ge)(ge)。螺(luo)(luo)(luo)紋(wen)(wen)(wen)(wen)(wen)(wen)(wen)環(huan)(huan)(huan)規(gui)(gui)是(shi)(shi)檢(jian)測外(wai)(wai)螺(luo)(luo)(luo)紋(wen)(wen)(wen)(wen)(wen)(wen)(wen)好(hao)壞(huai)的(de),它(ta)只(zhi)是(shi)(shi)檢(jian)測外(wai)(wai)螺(luo)(luo)(luo)紋(wen)(wen)(wen)(wen)(wen)(wen)(wen)是(shi)(shi)否(fou)(fou)可(ke)以符(fu)合使(shi)用要求。螺(luo)(luo)(luo)紋(wen)(wen)(wen)(wen)(wen)(wen)(wen)環(huan)(huan)(huan)規(gui)(gui)比如：檢(jian)測M25螺(luo)(luo)(luo)距3.0的(de)螺(luo)(luo)(luo)紋(wen)(wen)(wen)(wen)(wen)(wen)(wen)是(shi)(shi)否(fou)(fou)符(fu)合工(gong)(gong)藝要求是(shi)(shi)用M25*3.0的(de)螺(luo)(luo)(luo)紋(wen)(wen)(wen)(wen)(wen)(wen)(wen)環(huan)(huan)(huan)規(gui)(gui)（有兩種(zhong)(zhong)，一個是(shi)(shi)通(tong)(tong)(tong)規(gui)(gui)，另一為(wei)止(zhi)(zhi)規(gui)(gui)）通(tong)(tong)(tong)規(gui)(gui)通(tong)(tong)(tong)，止(zhi)(zhi)規(gui)(gui)止(zhi)(zhi)，證明(ming)加工(gong)(gong)的(de)螺(luo)(luo)(luo)紋(wen)(wen)(wen)(wen)(wen)(wen)(wen)合格(ge)(ge)(ge)。

綜(zong)上(shang)，常說的(de)鋼筋連接套管止通(tong)規包含(han)塞規，或者說通(tong)常說的(de)止通(tong)規就是塞規。
