Three doors and windows chimney painting

　　(A) operation process to beautify the cooling tower chimney project

　　Door frame installation

　　During installation, it should be placed according to the horizontal elevation and plane position required by the design drawings, according to its opening direction and corresponding codes, with a small plumb hammer for horizontal and vertical correction, and then connected firmly with adjacent fixtures with braces.

　　Before the wall is built, the frame should be installed, and wooden bricks should be reserved in the frame to beautify the cooling tower chimney project according to the design requirements.

　　When leaving a hole due to conditions and other reasons

　　A wood brick shall be embedded in the masonry, and there shall be no less than three fixed points on each side, and the spacing between them shall not be greater than. ∽. m. One side of the wall with a wooden wedge is attached to the masonry, and the door frame is temporarily fixed in the doorway with a wooden wedge, and then nailed with a nail or a steel nail. Beautify cooling tower chimney project

　　B When there are no wooden bricks left in the masonry, fix the side of the door frame against the wall with a straight iron with a width of mm, a length of mm, and a thickness of ∽mm, and attach it to the wall. After temporarily fixing the door frame in the doorway with a wooden wedge, nail it with a nail gun or steel nail.

　　2.主煙囪油漆的順序和內(nèi)容

　　協(xié)調(diào)階段的冷卻塔煙囪美化工程

　　看圖紙→提出問(wèn)題→解決問(wèn)題→粉刷主煙囪，注意預(yù)留洞槽、預(yù)埋件、墻內(nèi)、樓板內(nèi)管道安裝、洞槽清理。

　　安裝階段

　　生活給水、消防給水、生活污水雨水排水管道安裝→試壓、隱蔽驗(yàn)收、充水閉水試驗(yàn)→衛(wèi)生潔具安裝設(shè)備試運(yùn)行。

　　驗(yàn)收階段

　　三煙囪涂裝技術(shù)要求

　　生活供水管

　　生活給水管采用國(guó)標(biāo)熱鍍鋅鋼管，材料按規(guī)定檢驗(yàn)合格后方可使用。

　　If the diameter of galvanized steel pipe is less than DN, threaded connection shall be adopted; if the pipe is installed, the exposed hemp filler shall be cleaned, and the internal dirt and sundries must be removed; the exposed parts where the installation is interrupted or completed shall be temporarily closed, and the threads of the pipe shall be regular; if there is broken or missing wires, it shall not be more than% of the total thread deduction; if the pipe diameter is greater than DN, flange connection shall be adopted, and the welding joint shall be internally and externally protected. The main pipe and the inlet pipe buried in the floor shall be painted by welding chimneys, and shall be embedded with civil works. The upper concrete can only be poured after passing the pressure test, and the test pressure shall not be less than. MPa. The internal and external anticorrosion treatment of this pipeline shall be done according to the design requirements.

　　安裝給水立管時(shí)，應(yīng)先根據(jù)圖紙找好平面尺寸位置，

　　管道水平安裝時(shí)，先檢查管道平面位置的管道中心標(biāo)高，根據(jù)驗(yàn)收規(guī)范確認(rèn)支架的正確定位，制作并埋設(shè)支撐支架?？偟囊笫潜ＷC垂直牢固，與管道緊密接觸。支架擬采用角鋼工，其中管徑< DN采用X角鋼，管徑> DN采用X角鋼，管徑< DN時(shí)吊桿采用φ元鋼，管徑> DN時(shí)采用φ鋼筋。美化冷卻塔煙囪工程

　　支吊架擬采用φ膨脹螺栓固定在建筑結(jié)構(gòu)墻板上，不影響結(jié)構(gòu)安全。泵房?jī)?nèi)管道的支吊架擬采用φ膨脹螺栓固定。

　　管道安裝后，必須對(duì)管道進(jìn)行校正和拉直，以確保管道水平和垂直安裝在支架上，并牢固固定。管道安裝后，請(qǐng)監(jiān)理煙囪油漆工和質(zhì)檢站檢查合格后，再做水壓試驗(yàn)，并填寫水壓試驗(yàn)記錄。隱蔽管道完成后，及時(shí)填寫隱蔽記錄，經(jīng)甲方等質(zhì)監(jiān)部門檢查合格后，做好簽證工作，再進(jìn)入下道工序。
