2、和沿地龍骨，各自交接后的龍骨，應(yīng)保持平整垂直，安裝牢固。（3）質(zhì)量關(guān)鍵要求1）上下檻與主體結(jié)構(gòu)連接牢固，上下檻不允許斷開，保證隔斷的整體性。嚴(yán)禁隔斷墻上連接件采用射釘固定在磚墻上。應(yīng)采用預(yù)埋件進(jìn)行連接。上下檻必須與主體結(jié)構(gòu)連接牢固。2）罩面板應(yīng)經(jīng)嚴(yán)格選材，表面應(yīng)平整光潔。安裝罩面板前應(yīng)嚴(yán)格檢查龍骨的垂直度和平整度。3、施工工藝（1）工藝流程彈線→安裝天地龍骨→豎向龍骨分檔→安裝豎向龍骨→安裝系統(tǒng)管、線→安裝橫向卡擋龍骨→安裝門洞口框→安裝第一層罩面板（一側(cè)）→安裝隔音棉→安裝第一層罩面板（另一側(cè)）→安裝第二層罩面

3、板（2）操作工藝1）彈線在基體上彈出水平線和豎向垂直線，以控制隔斷龍骨安裝的位置、龍骨的平直度和固定點。2）隔斷墻龍骨的安裝A、沿彈線位置固定沿頂和沿地龍骨，各自交接后的龍骨，應(yīng)保持平直。固定點間距應(yīng)不大于600mm，龍骨的端部必須固定牢固。邊框龍骨與基層之間，應(yīng)按設(shè)計要求安裝密封條。B、當(dāng)選用支撐卡系列龍骨時，應(yīng)先將支撐卡安裝在豎向龍骨的開口上，卡距為400-600mmnthemainterminal,andthetelephoneOfficeisresponsibleforprovidingtheapprop
