桶裝植筋膠的使用方法

1、定位

按(an)照(zhao)設計要求利用鋼筋(jin)探測儀(避(bi)開鋼筋(jin))準確確定(ding)鉆孔的(de)位置。

2、鉆孔

使用電動(dong)沖擊鉆在確定位(wei)置按(an)設(she)計(ji)要求(深度(du)、孔(kong)(kong)(kong)徑)鉆孔(kong)(kong)(kong)，為(wei)保證充分發揮被錨(mao)固鋼(gang)(gang)筋(jin)的(de)(de)作用，鋼(gang)(gang)筋(jin)的(de)(de)埋(mai)設(she)及孔(kong)(kong)(kong)徑應嚴(yan)格(ge)按(an)照設(she)計(ji)要求，鉆孔(kong)(kong)(kong)時不得(de)破壞(huai)原混(hun)凝土構(gou)(gou)件的(de)(de)結構(gou)(gou)，不得(de)切損構(gou)(gou)件原有主筋(jin)和其(qi)他受力鋼(gang)(gang)筋(jin)。成(cheng)孔(kong)(kong)(kong)后的(de)(de)孔(kong)(kong)(kong)壁必須(xu)完整(zheng)無(wu)(wu)損，無(wu)(wu)裂(lie)縫、蜂窩(wo)、孔(kong)(kong)(kong)道。(如(ru)果(guo)(guo)孔(kong)(kong)(kong)眼(yan)與(yu)構(gou)(gou)件鋼(gang)(gang)筋(jin)位(wei)置不相重(zhong)合，按(an)設(she)計(ji)圖布置膨脹螺栓用孔(kong)(kong)(kong)眼(yan)；如(ru)果(guo)(guo)孔(kong)(kong)(kong)眼(yan)與(yu)構(gou)(gou)件鋼(gang)(gang)筋(jin)位(wei)置相重(zhong)合時，為(wei)保證不傷原有構(gou)(gou)件鋼(gang)(gang)筋(jin)，將孔(kong)(kong)(kong)眼(yan)作適當(dang)的(de)(de)調整(zheng)，并將調整(zheng)后孔(kong)(kong)(kong)眼(yan)布置畫成(cheng)草(cao)圖或做好(hao)記錄)。

3、清孔

成孔(kong)(kong)(kong)后應(ying)立即清理，使(shi)用毛刷(shua)清除(chu)孔(kong)(kong)(kong)壁(bi)的(de)灰粉不得少于(yu)3次(ci)，吹出粉塵，孔(kong)(kong)(kong)內應(ying)完全干燥，使(shi)用棉紗蘸(zhan)取丙酮擦拭孔(kong)(kong)(kong)壁(bi)一遍(bian)。清孔(kong)(kong)(kong)后若不能及(ji)時(shi)(shi)植筋，必須(xu)臨時(shi)(shi)封堵孔(kong)(kong)(kong)口，防(fang)止塵土、砂礫等進入孔(kong)(kong)(kong)內。

4、鋼筋去污

采用機械方法或(huo)者鋼(gang)絲刷除去(qu)鋼(gang)筋(jin)植(zhi)(zhi)入(ru)部分表面鐵銹和(he)氧化層，然后(hou)使用丙酮除去(qu)鋼(gang)筋(jin)上(shang)殘(can)留的(de)油(you)污。已經處理過(guo)的(de)鋼(gang)筋(jin)應該盡快(kuai)植(zhi)(zhi)入(ru)孔內，避(bi)免重新生銹或(huo)粘上(shang)油(you)污。

5、配膠

按(an)需用(yong)膠量取(qu)桶裝植筋膠的A、B料(依照使用(yong)說明分別量取(qu))，并(bing)快(kuai)速混合均勻。

6、注膠

膠(jiao)液應盡快低壓注(zhu)入到(dao)孔中，排出氣泡，保(bao)證膠(jiao)層飽滿(man)。

7、植筋

插入鋼(gang)(gang)筋用(yong)固(gu)定(ding)(ding)卡(ka)在(zai)(zai)孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)兩端將鋼(gang)(gang)筋固(gu)定(ding)(ding)(因橫梁(liang)植筋孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)為通(tong)(tong)(tong)孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)，所以要(yao)保證鋼(gang)(gang)筋的(de)位置固(gu)定(ding)(ding))，在(zai)(zai)固(gu)定(ding)(ding)卡(ka)預留(liu)注膠孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)和(he)通(tong)(tong)(tong)氣孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)(注膠孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)設于固(gu)定(ding)(ding)卡(ka)下(xia)方，可任取一(yi)端；通(tong)(tong)(tong)氣孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)設于橫梁(liang)兩端固(gu)定(ding)(ding)卡(ka)上(shang)方并(bing)加設20cm向(xiang)上(shang)通(tong)(tong)(tong)氣管(guan)；通(tong)(tong)(tong)氣管(guan)管(guan)徑要(yao)小(xiao)且緊貼植筋孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)截面(mian)頂點(dian)，在(zai)(zai)植筋孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)截面(mian)頂點(dian)鑿(zao)一(yi)小(xiao)缺口安設通(tong)(tong)(tong)氣管(guan))，用(yong)快硬型(xing)環(huan)氧(yang)樹(shu)脂封塞(sai)孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)端(保證注膠孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)和(he)通(tong)(tong)(tong)氣孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)暢(chang)通(tong)(tong)(tong))。

8、養護固化

已經(jing)植(zhi)入孔內(nei)的鋼筋應(ying)在常溫下養護，不(bu)得擾(rao)動，24小時后可以(yi)進行(xing)下步施工作(zuo)業(掛鋼板(ban)粘(zhan)(zhan)貼)。一般20℃時粘(zhan)(zhan)合劑在3-5天可以(yi)完(wan)全(quan)固化，現(xian)場抽樣(yang)檢驗應(ying)該在五(wu)天以(yi)后進行(xing)。

注射式植筋膠使用方法

1、標定空位

由(you)設計單位設計，劃線確定(ding)定(ding)位植筋，看看我們的工程(cheng)哪些(xie)地方需(xu)要(yao)植筋加固(gu)。

2、鉆孔

嚴(yan)格按照技術參(can)數(shu)鉆孔(kong)(kong)，我(wo)們必須按照，且嚴(yan)格按照技術規定(ding)植筋(jin)鉆孔(kong)(kong)，如果(guo)不按照規定(ding)參(can)數(shu)，直接影響植筋(jin)的(de)拉拔效果(guo)，最終影響植筋(jin)效果(guo)。

3、清空孔內浮灰

吹(chui)盡(jin)孔(kong)(kong)(kong)內浮灰(hui)，毛(mao)刷(shua)刷(shua)干凈(jing)，反復刷(shua)、推(tui)(tui)(tui)，直到(dao)把孔(kong)(kong)(kong)清干凈(jing)，我們一定遵循(xun)原則“三(san)吹(chui)三(san)推(tui)(tui)(tui)”，顧(gu)名(ming)思義，就是用壓縮空(kong)氣(qi)吹(chui)盡(jin)孔(kong)(kong)(kong)內浮灰(hui)，再(zai)用毛(mao)刷(shua)刷(shua)和推(tui)(tui)(tui)，再(zai)一次吹(chui)，然后推(tui)(tui)(tui)，反復進行這(zhe)一步，直到(dao)孔(kong)(kong)(kong)內的浮灰(hui)干凈(jing)即可。

4、注膠前準備

在植筋(jin)膠(jiao)(jiao)膠(jiao)(jiao)瓶上(shang)裝好靜態混合(he)器(qi)，用膠(jiao)(jiao)槍先少量的(de)擠掉前面(mian)混合(he)不均(jun)勻的(de)膠(jiao)(jiao)，然后在孔(kong)內(nei)注膠(jiao)(jiao)。把前面(mian)不均(jun)勻的(de)膠(jiao)(jiao)擠掉，不均(jun)勻會達(da)不到效果，所(suo)以要擠掉。

5、注膠方法

保證從孔底至孔口的(de)順序，盡量不要混入氣泡，膠料(liao)應注(zhu)滿孔深的(de)2/3以上。根據(ju)我們十年加固材料(liao)經驗，注(zhu)入三分之二即可達(da)到最好(hao)的(de)植(zhi)筋效果(guo)。

6、旋入鋼筋或螺桿

將鋼筋或(huo)(huo)螺桿(gan)旋入孔(kong)中(zhong)，并上下抽動幾次，以保(bao)證(zheng)粘膠的均勻，不(bu)停的抽動，增(zeng)加受(shou)力(li)面積(ji)，最大范圍使膠料粘接在鋼筋(jin)或(huo)(huo)者(zhe)螺桿(gan)上。

7、固化養護

在常溫下養護時間為24小(xiao)時，期(qi)間不能(neng)搖動桿體，養護后即可承(cheng)重(zhong)。
