桶裝植筋膠的使用方法

1、定位

按照設(she)計要求(qiu)利用鋼(gang)筋(jin)探(tan)測儀(避開(kai)鋼(gang)筋(jin))準確(que)確(que)定鉆孔的(de)位置。

2、鉆孔

使(shi)用電動沖(chong)擊鉆(zhan)在確定位置(zhi)按設(she)計要求(qiu)(深(shen)度、孔(kong)(kong)徑)鉆(zhan)孔(kong)(kong)，為保證(zheng)充分發揮被錨(mao)固鋼(gang)(gang)筋(jin)的(de)(de)作用，鋼(gang)(gang)筋(jin)的(de)(de)埋設(she)及孔(kong)(kong)徑應嚴格按照設(she)計要求(qiu)，鉆(zhan)孔(kong)(kong)時不得(de)破壞原混凝土(tu)構件的(de)(de)結構，不得(de)切損構件原有(you)主筋(jin)和其(qi)他受力鋼(gang)(gang)筋(jin)。成孔(kong)(kong)后(hou)的(de)(de)孔(kong)(kong)壁必須完整(zheng)無(wu)損，無(wu)裂縫、蜂窩、孔(kong)(kong)道(dao)。(如(ru)果(guo)孔(kong)(kong)眼(yan)與構件鋼(gang)(gang)筋(jin)位置(zhi)不相(xiang)重合(he)，按設(she)計圖布置(zhi)膨脹螺栓用孔(kong)(kong)眼(yan)；如(ru)果(guo)孔(kong)(kong)眼(yan)與構件鋼(gang)(gang)筋(jin)位置(zhi)相(xiang)重合(he)時，為保證(zheng)不傷(shang)原有(you)構件鋼(gang)(gang)筋(jin)，將孔(kong)(kong)眼(yan)作適(shi)當的(de)(de)調(diao)整(zheng)，并將調(diao)整(zheng)后(hou)孔(kong)(kong)眼(yan)布置(zhi)畫成草圖或做(zuo)好記錄)。

3、清孔

成孔(kong)(kong)(kong)(kong)后(hou)應(ying)(ying)立即清(qing)理，使用(yong)毛刷清(qing)除孔(kong)(kong)(kong)(kong)壁(bi)的灰粉不得少(shao)于3次，吹(chui)出粉塵(chen)，孔(kong)(kong)(kong)(kong)內應(ying)(ying)完全干燥，使用(yong)棉(mian)紗蘸(zhan)取(qu)丙酮(tong)擦(ca)拭孔(kong)(kong)(kong)(kong)壁(bi)一(yi)遍(bian)。清(qing)孔(kong)(kong)(kong)(kong)后(hou)若不能及時植筋(jin)，必須臨(lin)時封(feng)堵孔(kong)(kong)(kong)(kong)口，防止(zhi)塵(chen)土、砂礫等進入孔(kong)(kong)(kong)(kong)內。

4、鋼筋去污

采用機械方法(fa)或者鋼(gang)絲刷除去(qu)鋼(gang)筋(jin)植入部(bu)分表(biao)面鐵銹和(he)氧化層，然(ran)后使(shi)用丙酮除去(qu)鋼(gang)筋(jin)上殘(can)留的油污。已(yi)經(jing)處理過的鋼(gang)筋(jin)應該盡(jin)快植入孔內，避免重(zhong)新生銹或粘上油污。

5、配膠

按需用膠(jiao)量(liang)取桶(tong)裝植筋(jin)膠(jiao)的(de)A、B料(依照(zhao)使用說明分別量(liang)取)，并快速混(hun)合(he)均(jun)勻。

6、注膠

膠液(ye)應盡快低(di)壓注入到孔中，排出氣(qi)泡，保證膠層(ceng)飽滿。

7、植筋

插(cha)入鋼(gang)(gang)(gang)筋用固(gu)(gu)定(ding)卡(ka)在(zai)孔(kong)(kong)兩端(duan)(duan)將(jiang)鋼(gang)(gang)(gang)筋固(gu)(gu)定(ding)(因橫梁植(zhi)筋孔(kong)(kong)為通(tong)(tong)(tong)(tong)(tong)(tong)孔(kong)(kong)，所以(yi)要保(bao)證鋼(gang)(gang)(gang)筋的位(wei)置(zhi)固(gu)(gu)定(ding))，在(zai)固(gu)(gu)定(ding)卡(ka)預(yu)留注膠孔(kong)(kong)和通(tong)(tong)(tong)(tong)(tong)(tong)氣(qi)(qi)(qi)孔(kong)(kong)(注膠孔(kong)(kong)設(she)(she)于(yu)固(gu)(gu)定(ding)卡(ka)下方，可(ke)任取一端(duan)(duan)；通(tong)(tong)(tong)(tong)(tong)(tong)氣(qi)(qi)(qi)孔(kong)(kong)設(she)(she)于(yu)橫梁兩端(duan)(duan)固(gu)(gu)定(ding)卡(ka)上方并加設(she)(she)20cm向(xiang)上通(tong)(tong)(tong)(tong)(tong)(tong)氣(qi)(qi)(qi)管；通(tong)(tong)(tong)(tong)(tong)(tong)氣(qi)(qi)(qi)管管徑要小(xiao)且緊貼植(zhi)筋孔(kong)(kong)截面(mian)頂點，在(zai)植(zhi)筋孔(kong)(kong)截面(mian)頂點鑿一小(xiao)缺(que)口安設(she)(she)通(tong)(tong)(tong)(tong)(tong)(tong)氣(qi)(qi)(qi)管)，用快硬(ying)型環氧樹脂封(feng)塞孔(kong)(kong)端(duan)(duan)(保(bao)證注膠孔(kong)(kong)和通(tong)(tong)(tong)(tong)(tong)(tong)氣(qi)(qi)(qi)孔(kong)(kong)暢通(tong)(tong)(tong)(tong)(tong)(tong))。

8、養護固化

已經植入孔內的鋼筋應在常溫下養護，不得(de)擾(rao)動(dong)，24小時后可(ke)以進行(xing)下步施工(gong)作業(ye)(掛鋼板粘(zhan)貼)。一般20℃時粘(zhan)合劑在3-5天(tian)可(ke)以完全固化，現場抽樣檢驗應該在五天(tian)以后進行(xing)。

注射式植筋膠使用方法

1、標定空位

由(you)設計(ji)單位(wei)設計(ji)，劃線確(que)定定位(wei)植筋(jin)(jin)，看(kan)看(kan)我(wo)們的工程(cheng)哪些地方需要(yao)植筋(jin)(jin)加固。

2、鉆孔

嚴格按(an)照(zhao)技術(shu)參(can)數(shu)鉆孔，我(wo)們必須(xu)按(an)照(zhao)，且嚴格按(an)照(zhao)技術(shu)規定(ding)植筋鉆孔，如果(guo)不按(an)照(zhao)規定(ding)參(can)數(shu)，直接影響(xiang)植筋的(de)拉拔(ba)效果(guo)，最終影響(xiang)植筋效果(guo)。

3、清空孔內浮灰

吹(chui)(chui)盡(jin)孔(kong)內(nei)(nei)浮灰，毛刷刷干(gan)凈(jing)，反(fan)復刷、推(tui)，直到把(ba)孔(kong)清干(gan)凈(jing)，我們一(yi)定(ding)遵循原則“三(san)吹(chui)(chui)三(san)推(tui)”，顧名(ming)思義，就是用(yong)壓縮空氣吹(chui)(chui)盡(jin)孔(kong)內(nei)(nei)浮灰，再用(yong)毛刷刷和推(tui)，再一(yi)次(ci)吹(chui)(chui)，然后推(tui)，反(fan)復進行這一(yi)步，直到孔(kong)內(nei)(nei)的浮灰干(gan)凈(jing)即可。

4、注膠前準備

在植筋膠膠瓶上裝好靜態混合(he)(he)器，用膠槍先少量的(de)擠掉前面混合(he)(he)不均(jun)勻的(de)膠，然后(hou)在孔內注膠。把前面不均(jun)勻的(de)膠擠掉，不均(jun)勻會達不到效果(guo)，所以要擠掉。

5、注膠方法

保證從(cong)孔(kong)(kong)底至孔(kong)(kong)口(kou)的順序(xu)，盡(jin)量(liang)不要混入氣(qi)泡，膠料(liao)應注滿孔(kong)(kong)深的2/3以(yi)上(shang)。根(gen)據我們(men)十年(nian)加固材料(liao)經驗(yan)，注入三分之二(er)即(ji)可達到(dao)最好的植(zhi)筋效果。

6、旋入鋼筋或螺桿

將鋼筋或螺(luo)桿(gan)旋入孔中(zhong)，并上(shang)下抽(chou)動(dong)幾次，以(yi)保證粘(zhan)膠的(de)均勻，不停的(de)抽(chou)動(dong)，增加受力面(mian)積，最大范圍使膠料粘(zhan)接在鋼筋或者螺(luo)桿(gan)上(shang)。

7、固化養護

在常溫(wen)下養(yang)護(hu)時間為(wei)24小(xiao)時，期間不能(neng)搖(yao)動桿體，養(yang)護(hu)后(hou)即可承重。
