不锈钢雨棚施工方案.doc

雨棚施工方案一、工程概况： 二、雨棚生产工艺与施工方法：加工准备及下料 →测量放线定位→开挖基槽、基坑→C20砼垫层浇筑→钢筋安装→预埋件安装处理→C20砼捣制基础→连接钢管焊接→不锈钢立柱安装焊接→防锈喷漆处理→不锈钢雨棚框架加工制作安装→不锈钢雨棚面板制作安装→护栏制作安装→打磨防锈→上下打胶→修补检验→清理、清洗现场→竣工验收三、室内电梯门两边不锈钢护栏： 加工准备及下料 →测量放线定位→钻孔→预埋膨胀螺杆→安装加强焊接钢板垫块→焊接立柱→打磨防锈→修补检验→清理、清洗现场→竣工验收四、施工工艺及施工要点： 1、加工准备及下料：按照施工图放样，放样和号料时要预留焊接收缩量和加工余量， 根据放样作样板钢材矫正：钢材下料前必须先进行矫正，矫正后的偏差值不应超过规范规定的允许偏差值，以保证下料的质量热加工的型钢先热加工，待冷却后再号孔钢板预埋件及其他零件切割钻孔及喷防腐漆处理 2、测量放线：根据土建标高基准线测预埋件标高中心线，检查预埋件标高偏差、左右偏差整理结果，确定预埋件分隔的调整处理方案沿外墙外沿弹出墨线定出预埋件顶标高线 3、预埋件安装处理：定位预埋件安装位置，打钻安装。

要求预埋件位置准确、埋设牢固标高偏差不大于5mm，左右位移不大于10mm 4、预埋件和立柱焊接：需检查焊接节点，调正立柱的垂直度，准确无误方能进行焊接靠边一条立柱准确无误后，安装另一条立柱，就位准确后点焊然后以此两条立柱为基准拉出悬挂臂的最高、最底标高线，按顺序施工 5、校准检验：立柱安装后首先检查现场连接部位的质量立柱安装质量主要检查立柱竖向面的是否垂直；受压对立柱竖向面的侧面下垂；立柱坡度保证立柱符合设计受力状态及整体稳定要求 6、连接受力拉索：定位拉杆基准线、标高线，按要求安装其它连接件，焊接栏杆 7、防锈喷漆处理：应清除熔渣及飞溅物，不锈钢件表面喷白漆多遍防锈喷漆处理应符合设计要求或施工规范的规定 8、不锈钢雨棚加工制作安装：按设计要求结合实测尺寸确定尺寸，以及的水平、垂直位置，厂家加工制作安装不锈钢立柱，雨棚临时固定后进行调整，调整标准横平、竖直、面平偏差不得超过规定偏差 9、调整检验：不锈钢雨棚进行整体调整检验，调整标准横平、竖直、面平偏差不得超过规定偏差 10、上下打胶：充分清洁玻璃间缝隙，不应有水、油渍、涂料、铁锈、水泥砂浆、灰尘等充分清洁粘结面，加以干燥。

为调整缝的深度，避免三边粘胶在缝两侧贴保护胶纸保护玻璃不被污染上下同时打密封胶，注胶后将胶缝表面抹平，去掉多余的胶注胶完毕，将保护纸撕掉，必要时用溶剂擦拭表面胶在未完全硬化前，不要沾染灰尘和划伤 11、修补检验：局部修补检验 12、清理现场：保护和清洗现场 13、竣工验收：竣工验收五、质量控制 1、质量标准：请参照《钢结构设计规范》(GB50017—2003)、《钢结构工程施工质量验收规范》（GB50205-2001） 2、质量管理要点：材料控制：不锈钢雨棚所使用的各种材料必须符合设计和规范要求材料采购前必须弄清楚规范中对该种材料有何质量要求各种构件在运输过程中必须有可靠的保护措施构件外观表面无明显的凹面和损伤，划痕深度不大于0.5mm焊疤、飞溅物、毛刺应清理干净螺栓孔光滑，无毛刺，孔壁垂直度偏差不大于板厚的2%，孔圆度偏差不大于1%悬挂臂安装焊接：悬挂臂安装焊接是雨棚施工中比较繁琐的工序，悬挂臂安装是否准确将影响整过施工过程测量人员在工作中必须反复校对，确保放线精确，坡度正确悬挂臂与预埋件的连接施工中，必须用合格焊工焊接、防锈、安装精度必须合格钢材的品种、规格、型号和质量，必须符合设计要求、实测及有关标准的规定。

钢材切割面必须无裂纹、夹渣分层和大于lmm的缺楞构件外观表面无明显的凹面和损伤，划痕深度不大于0.5mm焊疤、飞溅物、毛刺应清理干净螺栓孔光滑，无毛刺，孔壁垂直度偏差不大于板厚的2%，孔圆度偏差不大于1%六、安全措施 1、安装雨棚用的施工机具在使用前必须进行严格检验 2、施工人员配备必要的劳动保护用品，防止人员及物件坠落 3、防止密封材料在工程使用中溶剂中毒，且要保管好溶剂，以防发生火灾 广州市维雅装饰设计（英文版 ） Two regulations promulgated for implementation is in the party in power for a long time and the rule of law conditions, the implementation of comprehensive strictly strategic plan, implementation in accordance with the rules and discipline to manage the party, strengthen inner-party supervision of major initiatives. The two regulations supporting each other, the < code > adhere to a positive advocate, focusing on morality is of Party members and Party leading cadres can see, enough to get a high standard; < rule > around the party discipline, disciplinary ruler requirements, listed as "negative list, focusing on vertical gauge, draw the party organizations and Party members do not touch the" bottom line ". Here, the main from four square face two party rules of interpretation: the first part introduces two party Revised regulations the necessity and the revision process; the second part is the interpretation of the two fundamental principles of the revision of laws and regulations in the party; the third part introduces two party regulations modified the main changes and needs to grasp several key problems; the fourth part on how to grasp the implementation of the two regulations of the party. < code > and < Regulations > revised the necessity and revised history of the CPC Central Committee the amendment to the Chinese Communist Party members and leading cadres honest politics several guidelines > and < Chinese Communist Party discipline and Punishment Regulations > column 1 by 2015 to strengthen party laws and regulations focus. Two party regulations revision work lasted a Years, pooling the wisdom of the whole party, ideological consensus, draw historical experience, respect for the wisdom of our predecessors, which reflects the unity of inheritance and innovation; follow the correct direction, grasp the limited goals, adhere to the party's leadership, to solve the masses of the people reflect a focus on the problem. The new revision of the < code > and < rule >, reflects the party's 18 and the eighth session of the third, the spirit of the fourth plenary session, reflecting the experience of studying and implementing the General Secretary Xi Jinping series of important speech, reflects the party's eighteen years comprehensive strictly practice. (a) revised two regulations of the party need of < the ICAC guidelines > in < in 1997 Leaders as members of the Communist Party of China clean politics certain criteria (Trial) > based on revised, the promulgation and implementation of January 2010, to strengthen the construction of the contingent of leading cadres play an important role. But with the party to manage the party strictly administering the deepening, has not been able to fully meet the actual needs. Content is too complicated, "eight prohibition, 52 are not allowed to" hard to remember, and also difficult to put into practice; the second is concisely positive advocated by the lack of prohibited provisions excessive, no autonomy requirements; the third is banned terms and discipline law, both with the party disciplin。
