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.
c安装时应考虑抹灰层的厚度，竖框应与抹灰皮平齐。
第八章给排水烟囱涂装方法美化冷却塔烟囱工程
1.冷却塔烟囱工程美化总体布置及要求
该安装烟囱油漆质量标准优良。
工期与土建烟囱粉刷紧密配合，烟囱粉刷安装进度随土建总体计划和进度的变化而调整，确保烟囱粉刷安装的顺利进行和任务的圆满完成。美化冷却塔烟囱工程
根据本次烟囱粉刷的特点，拟定烟囱粉刷方案的原则是先安装地下部分，再安装地上部分，先主管后支管。管道安装应遵循以下原则:小管换大管，支管换主管；有压力管做无压力管；一般来说，管道是隔热的。楼层内所有管道应在土建主体的烟囱粉刷后安装，室外安装的烟囱粉刷。
2.主烟囱油漆的顺序和内容
协调阶段的冷却塔烟囱美化工程
看图纸→提出问题→解决问题→粉刷主烟囱，注意预留洞槽、预埋件、墙内、楼板内管道安装、洞槽清理。
安装阶段
生活给水、消防给水、生活污水雨水排水管道安装→试压、隐蔽验收、充水闭水试验→卫生洁具安装设备试运行。
验收阶段
水试验中冲洗和消毒的竣工验收
三烟囱涂装技术要求
生活供水管
生活给水管采用国标热镀锌钢管，材料按规定检验合格后方可使用。
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.
安装给水立管时，应先根据图纸找好平面尺寸位置，
管道水平安装时，先检查管道平面位置的管道中心标高，根据验收规范确认支架的正确定位，制作并埋设支撑支架。总的要求是保证垂直牢固，与管道紧密接触。支架拟采用角钢工，其中管径< DN采用X角钢，管径> DN采用X角钢，管径< DN时吊杆采用φ元钢，管径> DN时采用φ钢筋。美化冷却塔烟囱工程
支吊架拟采用φ膨胀螺栓固定在建筑结构墙板上，不影响结构安全。泵房内管道的支吊架拟采用φ膨胀螺栓固定。
管道安装后，必须对管道进行校正和拉直，以确保管道水平和垂直安装在支架上，并牢固固定。管道安装后，请监理烟囱油漆工和质检站检查合格后，再做水压试验，并填写水压试验记录。隐蔽管道完成后，及时填写隐蔽记录，经甲方等质监部门检查合格后，做好签证工作，再进入下道工序。
排水管道
根据设计要求，排水管道和通风管道的立管和横管采用国标加厚承插铸铁管。石棉水泥冲孔。钻孔前需用油麻填充，深度不得超过承口深度。压力排水管采用焊接钢管；雨水管采用PVC塑料管，连接口采用胶水连接；空调排水采用镀锌钢管，立管采用首层PVC塑料排水管接雨水管。美化冷却塔烟囱工程
安装位置、数量等。塑料排水管道上的检查口、清扫口、雨水斗膨胀膨胀节应符合设计和烟囱涂装工艺及规范要求。排水立管的检查口应安装在距地面m处，检查口的朝向应便于维修；隐藏式立管应在检查口配备一个检修门。二层所有排水管道均设有清扫口。雨水管与雨水斗的连接是封闭的，不允许有敞开的水桶。
管道固定支架之间的距离，水平管道φ→。m φ→。m φ→。m，垂直管道不大于m，高度小于或等于m时，应设置固定件。当高度大于m时，应设置固定件，固定件应尽可能靠近立管的下边缘。管道支架结构合理，埋设平整牢固，排列整齐，支架与管道紧密接触，排水横管敷设在梁底。安装排水塑料管。当层高≤m时，每层应设一个伸缩缝；层高为m时，应根据扩展量确定。美化冷却塔烟囱工程
