碳纤维粘贴加固施工方案.doc

ocusing on ways and means of improving and upgrading work, further development of three to split. (A) fully grasp no unauthorised created. The township no unauthorised created the existing building one household, one document survey and file storage work must be unconditional and full coverage. Main corridor leading to the town (road, river) village, the Central built-up area of the town on both sides must be to create a no unauthorised village. According to five hundred villages created and shanty towns, villages, old houses, reconstruction of old plant, expand create, upgrading creates files, the real no unauthorised village created into the benefit of the people of very good thing. (B) to strictly manage count as unauthorised controls. Promoting the new control work to move the center of gravity, management measures to the front, and earnestly pipes effectively. A strict new unauthorised network responsibility. Sectors such as land, housing and basic stations (stations) and the Township of grid accountability mechanisms must be strictly in accordance with the new regulatory requirements, effective implementation of the area of responsibility of the new inspections, suppression, demolition work to ensure that the new zero tolerance. Second, public security, water, electricity, water, oceans and fisheries, tourism collaboration, market supervision departments should strictly enforce the illegal construction of disposal of relevant provisions of the regulations, effective fulfilment of responsibilities, particularly in electricity and water supply, and other units may not be new illegal buildings to supply water and electricity supply. While more regulation to prevent personal privacy violations. Illicit trading in illegal construction in the Ministry of public security sector to strictly from the blow. Three is to create additional offence reporting system of incentives. According to building law and covers an area of nature, to report timely degree divided report grade, effective after the removal of certain incentives. (C) integrated implementation , building demolition, modification, use combination. Demolition is the means and purpose built is. To adhere to the building demolished, combination of construction and demolition waste, demolished with combined efforts to improve the scientific level of three to split; second, we must pay attention to three to split and five hundred and five water treatment, three of the four sides, the shackDistrict transformation, and dangerous old room transformation and two road sides, series work organic combined up, active do River, and along demolition work, and manpower advance village in the, and old residential demolition work, to improved masses housing conditions and live environment; three to put three modified a split as traditional low, and small, and bulk industry structure transformation upgrade of important initiatives to caught, speed up advance industry Park, effective optimization park environment 混凝土梁、楼板碳纤维加固施工方案一、工程概况本工程为工程，因业主使用功能需要在六层安装医疗设备，但原六层楼面结构无法满足设备安装需要；为了满足功能（安装医疗设备）的需要，业主特委托专业设计公司对原六层结构（梁、板）进行碳纤维加固和相关技术处理设计；业主委托我公司承担六层结构（梁、板）碳纤维加固施工任务。我公司接到施工任务后，根据碳纤维加固设计施工图要求：对原六层部分砼楼板和砼梁的上表面和下表面用碳纤维布进行加固处理；但在碳纤维布加固施工前，需要搭设满堂钢管脚手架对原梁板混凝土基层按以下方法进行处理：一、梁、板加固范围下部满搭钢管脚手架（搭设标准按规范）。二、剔除梁、板碳纤维加固部位的水泥砂浆找平层。三、对加固部位的混凝土基层按规范和施工工艺进行打磨和清理。对经过剔凿、清理部分混凝土结构，用高于原结构混凝土强度一个等级的环氧砂浆进行修补、复原，达到表面坚实和平整，具体按以下方案对楼板和梁进行碳纤维加固。 二、编制依据 1、混凝土结构加固设计规范（GB50367-2006） 2、钢筋焊接及验收规程（JGJ18-2003） 3、混凝土结构工程施工质量验收规范(GB50204-2002) 4、地下工程防水技术规范（GB50108-2001） 5、混凝土结构后锚固技术规程（JGJ145-2004） 6、六层梁、板结构加固施工图 7、施工现场实际情况 三、施工要求 1、一般要求粘贴碳纤维片材加固修复结构应由熟悉该技术施工工艺的专业施工队伍完成，并应有加固修复方案和施工技术措施。 2、材料要求1）采用高性能、粘结强度高的A级环氧性面料纤维粘浸胶。2）国产碳纤维布300克/平米，抗拉强度大于等于3500MPa。3）粘贴碳纤维织物加固混凝土结构板时，应使用与基材及碳纤维有良好适配性的粘结剂。使用前确定碳纤维布及粘接剂性能检测合格。 3、施工工艺流程： 施工准备 脚手架搭设表面处理配制并涂刷底层树脂配制找平材料并对不平整处修复处理配制并涂刷浸渍树脂或粘贴树脂粘贴碳纤维片材表面防护脚手架拆除 四、施工工序 1、施工准备 1)粘结剂必须有合格证明及检验报告。 2)碳纤维布必须有合格证明及检验报告。 3)压接钢片及射钉必须有合格证明及检验报告。 4)主要机具：角磨机、吹风机、滚压机、射钉枪等。 5)拆除碳纤维布所在部位影响施工的附属设施。 6)粘贴碳纤维布用的粘结剂和钢板准备完毕，并检查合格。 7)施工工具经过调试、运转合格。 8)项目经理及项目技术负责人根据施工方案对操作班组进行全面技术交底。 2、脚手架搭设按图纸碳纤维加固位置搭立满堂脚手架，立杆纵横间距0.5m，水平杆步距1.2m，支架应搭设2.3米高,以满足施工安全和施工条件。 3、混凝土基底处理1)将原楼板混凝土垫层剔凿、清除干净并达到结构层。2)对经过剔凿、清理部分，用高于原构件混凝土强度的环氧砂浆进行修补、复原，达到表面平整。3)将构件表面凸出部分（混凝土构件交接部位、模板的段差等）打磨平整。修整后的段差要平顺。棱角的部位，用磨光机磨成圆角。圆角半径最小不得小于20mm。4)清洗打磨过的构件表面，并使其充分干燥。5)施工前应按设计图纸在需加固部位放线、定位。 4、涂底涂树脂1)把底涂树脂的主剂和固化剂按规定比例称量准确后放入容器内，用搅拌器拌合均匀。一次调和量应以在可使用时间内用完为准。超过可使用时间不得再用。2)在底涂树脂中严禁添加溶剂。含有溶剂的毛刷或用溶剂弄湿了的滚筒不得使用。3)用滚筒刷均匀地涂抹底涂树脂。4)底涂树脂固化后，在构件表面有凝结凸起时，要用砂纸磨光。磨光后若露出混凝土基面，应再补涂底涂树脂。 5、构件表面的残缺修补 1)构件表面凹陷部位（蜂窝、麻面、小孔等）应用找平树脂填平，修复至表面平整。2)内角、段差、起拱等要用找平树脂填补，使之平顺。在残缺修补中使用找平树脂时，要在气温5以上，相对湿度RH85%时，如无有效措施时不得施工。2)防止碳纤维片受损。碳纤维片在运输、储存、裁切和粘贴过程中，严禁弯折。因此，贴片前应用钢直尺与壁纸刀按规定尺寸裁切碳纤维片，每段长度一般以不超过6米为宜。3)碳纤维片裁切时应预先在裁切位置粘贴宽胶带，在宽胶带正中位置进行裁切，以使裁切后碳纤维片的断头齐整不脱丝。4)碳纤维片纵向接头必须搭接10cm以上。该部位应多涂粘结树脂。碳纤维片横向不需要搭接。5)粘结树脂的主剂和固化剂应按规定的比例称量准确，装入容器，用搅拌器搅拌均匀。一次调和量应以在可使用时间内用完为准。6)下涂：贴片前用滚筒刷均匀地涂抹粘结树脂，称为下涂。涂量是根据施工部位及施工面的粗糙程度而变化的。拱起部分、拐角部分、碳纤维片搭接部位以及残缺修补处要多涂一些，但是必须涂抹均匀。7)贴片时，在碳纤维片和树脂之间不应残留空气形成气泡造成空鼓。为此，可用罗拉（专用工具）沿着纤维方向在碳纤维片上滚压多次，对角隅处应向着角隅滚压，对拱起的部位要向相反的方向滚压，以去除气泡，使粘结树脂均匀地充分渗浸入碳纤维片的碳纤维束中。8)上涂：碳纤维片施工30分钟（根据干燥程度）后，用滚筒刷均匀涂抹粘结树脂，称为上涂。上涂时和上述步骤一样，用脱泡罗拉沿碳纤维方向用力滚压多次，使碳纤维片内部补充、渗浸粘结树脂。9)进行空鼓检查，并进行处理。 7、养护1)粘贴碳纤维片后，需自然养护24小时达到初期固化，并应保证固化期间不受干扰。2)在每道工序以后树脂固化之前，宜用塑料薄膜等遮挡以防止风沙或雨水侵袭。3)碳纤维片粘贴后达到设计强度所需自然养护的时间：平均气温在10以下时，需要2周；平均气温在10以上20以下时，需要12周；平均气温高于20时，需要1周。在此期间应防止贴片部分受到硬性冲击。 五、质量要求所有进场材料，包括碳纤维片材和胶结材料，应符合质量标准，并具有产品出厂合格证，其各种性能指标及技术参数均应符合本工程加固补强设计要求，适合现场温度、湿度条件。碳纤维片材在运输、储存中不得受挤压，以免碳纤维受损。也不得直接日晒和雨淋。胶结材料应阴凉密闭储存。各工序的施工质量，由工长（或班组长）负责指导、监督。每一工序完成后督促操作小组自检，确认合格并提请技术员检查认可后才能进行下道工序，否则必须返修至合格为止。贴片前及以后，还要由技术员请业主代表或监理人员检查，作贴片数量与质量的签认。不贴片的部位，最后一道工序也要业主代表或监理人员签认。 六、质量标准 1、保证项目： 粘贴碳纤维布所用的碳纤维片材、配套树脂类粘结材料必须具有产品合格证、质检部门的产品性能检测报告。 粘结剂的的配合比、原材料计量、搅拌，必须符合施工规范规定。 2、一般项目： 碳纤维布沿纤维受力方向的搭接长度不应小于100mm，当碳纤维布沿其纤维方向需绕构件转角粘贴时，构件转角处外表面的曲率半径不应小于20mm。 3、允许偏差项目： 碳纤维片材的实际粘贴面积不应少于设计面积，位置偏差不应大于10mm，总有效粘结面积不应低于95%。 七、检验和验收 1、施工开始前，应确认碳纤维片材和粘结剂、底层树脂，找平材料的产品合格证、质量检验报告，各项性能应满足要求。 2、材料性能抽样检验。对不同批次进场的材料，按照相关的验收规范进行碳纤维及胶黏材料的性能抽样检验。 3、施工质量检验及验收标准列于下表。施工质量检验及验收标准检验项目合格标准检验方法频数碳纤维片粘贴位置与设计要求位置相比，中心线偏差10mm钢尺测量全部碳纤维粘贴量设计数量根据测量计算全部粘贴质量1.单个空鼓面积10000mm2充胶修复，10000mm2割除修补；2.空鼓总面积占总粘贴面积5%锤击法或其它有效方法抽样或全部 4、粘结质量不符合要求割除修补时，应沿空鼓边沿，将空鼓部分的碳纤维割除，以每边向外缘扩展100mm大小之同样碳纤维材料，用同样粘结剂，补贴在原处。 5、验收时可按相关规范规定对施工质量进行现场抽样检验。 八、安全注意事项 1、碳纤维为导电材料，施工时应使其远离电气设备，或采取可靠保护措施。 2、各种粘结剂应在其说明书规定的环境温度中密封储存，并远离火源，且避免日光直射。 3、粘结剂的配制应在室内进行，其操作环境及施工现场均应保持良好通风。 4、施工人员应带防护面罩、手套和着工作服。 5、各种粘结剂材料不得沾染生活水源。废弃物不得倒入下水道，应按环保要求集中处理。 6、进入施工现场人员都要佩戴安全帽，进行高处作业都要求佩带安全带。 7、对施工用电、脚手架、砼现场搅拌、“三宝”及“四口”防护等制订专项措施。对施工中存在不安全因素进行预先分析，制订切实可行的施工安全技术措施，确保施工安全。 8、做好各工种的安全技术交底，以便更好的贯彻执行安全技术措施。 9、所有特种作业人员均应经专门培训考试合格，持证上岗。 10、加强施工现场的安全检查监督，开展班前安全活动、班组安全日活动，从而提高工人安全意识和安全技能。 11、在施工现场适当位置挂设安全标语，在危险部位、重点部位悬挂安全标志，以提高现场所有人员的警惕性，减少人们的不安全行为。 12、严格执行施工现场临时用电安全技术规范，认真按照用电方案施工。实行“三相五线制”，设置三级漏电保护，做到“一机一箱一闸一漏电”保护。 13、现场配备的配电箱、开关箱均上锁，由专职电工保管，露天的配电箱及开关箱均加设防雨顶盖。维修设备时，切断电源，并挂“有人维修，严禁合闸”的警示牌，严禁带电工作。夜班作业，照明由电工统一布设，并且跟班管理，不准施工班组擅自私拉乱接。 14、各种机具的防护罩、安全装置均齐全，每机一闸一漏电，并与专用保护零线进行接零保护。 15、施工现场所有临时设施均按要求采用非燃料搭设，符合防火要求。 16、加强消防安全意识教育，做到防重于治。加强现场用电管理，对施工电焊、气焊做到按规程操作。to produce white smoke, so twice, cold.

Five, firmly implement, promoting work ahead, to create highlights. Third deployment, implementation of seven, then it is imperative to strengthen responsibility and improve the mechanisms and implementation. All localities and departments must be convinced that goals, going all out, mustering spirit, work together to ensure that this years objectives carry out tasks, at the forefront. First, we must strengthen the leadership to implement. Departments at all levels should always work and rural five water treatment, three to split in an important position, and carry the main responsibility, main leader personally, leaders arrested and layers of responsibility rank transmission pressure established hierarchical accountability, and work together to promote the work of the mechanism, a concerted effort pay attention to implementation. County nongban, flood, three to one down to further play a leading catch total, integrated and coordinated role of all kinds is long, Sheriff Inspector to effectively fulfill their responsibilities, formed the alignment on the fire line and management a lively situation. Second, we must strengthen the test implementation of the Governor. Role play the Governor got the baton, for agricultural and rural focus and five water treatment, three to split work, refine improve assessment methods and evaluation system, accurate assessment. Combined with dare play, tree benchmark style building five major operations, carry on and gain firsthand experience of supervision, in particular, to strengthen the focus on the long signs go left, names such as supervision, urged all levels longer on duty in place. Through the supervisory assessm
