is one of the practical form of values. The so-called values refers to the objective things are of no value and the value of fundamental perspective. Different values, peoples behaviour, attitudes, ways are different. People-oriented focus on human value and reality, we need the broadest masses as values. Adhere to people-oriented values, is to make the economy more development, improve democracy, cultural prosperity, and live a happier; is deeply concerned that human development and human values, development of social and human development of rational unified, insisted in the material civilization, political civilization and spiritual civilization in the overall advancement of Socialist civilization to a higher level. Also want to see that persons value is not only meet your needs, also is to meet the needs of others and the community. Adhere to people-oriented, to strongly advocate every community member, serve others, beneficial to the community of people. The so-called Outlook, attitude is on the record, including who, how to create a record of achievements, how to evaluate performance, and so on. What values, what kind of Outlook. Adhere to people-oriented Outlook, is on the premise of respecting the interests and power of people, creating a popular, warm hearts, steady heart performance, creating serve for one officer, the benefit of achievements, and overall construction of well-off society and promoting the all-round development of peoples performance. Achievement evaluation in both economic accomplishments, take another look at the effectiveness of social progress; changes in both urban and rural change; both hard environment to strengthen and take another look at the soft environment improvement momentum of development at present, depending on the potential for sustainable development. Leave people to talk about values are worthless and leave people to talk about Outlook is not what the performance. 4. people responded to the starting point of the question, and replied to questions point. Man is the sum of social relationships. We cannot leave the chichuanyongdu, housing, tourism and entertainment, entertaining, and even certain political, economic, cultural and social environment, and so on. Due to human needs, all walks of life will come into being. People create for their survival, and continue enjoying the results of the construction. Colorful in the transformation of the people of the world, community vitality in the creation of man. Therefore, any work we do, the starting point is human, what are people. Us speed up development, the core of which is to meet the needs of people, including survival needs, emotional needs and self-actualization needs. It should be noted that people are not machines, not the slave of an object, not to be controlled. People have their own personality, has its own personality, has its own dignity. Person in need of care, you need to understand, need to meet. It is said that in the agricultural society, people plant; in industrial society, man is an animal; the information society, return甬台温铁路房建标永嘉火车站 脚手架施工方案 目录第一章、工程概况1第二章、钢管贝雷支架施工模板计算1第三章、钢管贝雷支架受力计算3第四章、施工操作6第五章、模板安装要求7第六章、模板拆除要求8第七章、注意事项8钢管贝雷梁柱式支架施工方案 第一章、工程概况该工程为甬台温新建铁路永嘉火车站，处于浙江省温州市永嘉县千石村。甬台温铁路的建设技术标准为一级双线电气化铁路，设计时速为200千米，预留时速可提升到250-300千米。永嘉站高架站台工程采用钻孔灌注桩基础、钢管砼柱及钢筋砼柱，上部设计为钢结构雨棚。钢管柱的顶标高为16.35m。站台总长度为450米，站台面的结构标高为8.811米。该高架站台分左右两幅，每幅宽度均为6m，各15跨，跨径除靠近站房范围内的两跨跨度为9.1m外，其余均为10.9m。地勘报告显示，该项目地层分布，由上至下主要为：素填土，淤泥，淤泥质黏土，细圆砾土。 第二章、钢管贝雷支架施工模板计算 1、结构说明永嘉火车站站台部分，梁截面为400900、300400、250500、200400等，顶板厚为150，柱底承台面为16004000米，厚2000。我部采用贝雷片拼装桁架主施工承重结构进行施工。纵梁跨度最大10.9米，支墩顶安装2根HN396199713H型钢梁作为分配梁，分配梁上铺设贝雷梁；每组贝雷片采用标准支撑架进行连接。支墩采用2738钢管立柱，搁置在承台顶面上,立柱顶、底部均与钢板焊接，为提高支墩的稳定性，在各排支墩钢管之间纵向横向均设置槽钢、角钢连接。贝雷纵梁顶面设置10cm12cm木方做横向分配梁、6m8cm木方纵向分配梁；模板系统由侧模、底模、等组成。该工程侧模、底模均采用高强度防水竹胶板制作。2、受力验算依据2.1、永嘉火车站站台施工图2.2、路桥施工计算手册2.3、公路施工计册：桥涵2.4、公路桥涵设计通用规范（JTG D60-2004）2.5、公路桥涵施工技术规范（JTJ041-2000）2.6、公路桥涵钢结构及木结构设计规范（JTJ025）2.7、钢结构设计规范（GB50017-2003）3、荷载分析钢筋混凝土重量AWLK2（300700）：q1=5.46KN/mAWLK4（400900）：q2=9.36KN/mAWLK5（400900）：q3=9.36KN/mAL1（250500）：q4=3.25KN/mAL3（200400）：q5=2.08KN/m混凝土顶板（厚度150）: q6=3.9KN/m2模板、枋木荷载：q7 =1.5KN/m2设备及人工荷载：q8=2.5KN/m2砼浇注冲击荷载：q9 =2kN/m2砼振捣荷载：q10=2kN/m24、模板受力计算底模板为受弯结构,需要验算其抗弯强度和刚度，通过对比, 梁高为900米时横梁下底模板受力最大,仅验算该处模板，按三跨连续梁计算。静荷载标准值:(底模下木枋间距为200)p1=9.36KN/m +1.5KN/ m20.40m=9.96KN/m活荷载标准值:p2= (2.5+2.0+2.0)0.4=0.975kN/m竹夹板的截面惯性矩I和截面抵抗矩W分别为:W=40.01.21.2/6 = 9.6cm3I=40.01.21.21.2/12 =5.76cm4(1)抗弯强度计算= M/W 竹夹板的抗弯强度设计值，取9.5Mpa；M = 0.1ql2= 0.1(1.29.96+1.40.975)0.20.2=0.05325kN.m = M / W= 0.0532510001000/9600=5.547Mpa模板的抗弯强度验算 ，满足要求!(2)挠度计算E=7103 MPaf=5ql4/384EI=513.3172004/(384700057600)=0.688mm模板的最大挠度小于L/250=0.8mm,满足要求! 第三章、钢管贝雷支架受力计算1、首先根据设计要求及相关资料，计算出荷载值。恒载标准值计算表活载标准值计算表2、H型钢托梁的计算。（计算书附后） 3、确定钢管立柱的截面大小及厚度。钢立柱计算书 第四章、施工操作工艺流程：地面拼装吊车吊装现场加固高空防护搭设扣件式脚手架模板体系地面拼装：贝雷架通过穿上销钉后插销锁定。每片贝雷梁需3个单片组成33=9米长。组装完成后检查销钉是否牢靠，吊车吊装：考虑到该中空部位跨度10.2米，需要组装成的贝雷梁9米，单片贝雷梁重0.9吨，再结合现场20T汽车吊的起重量，完全能够一次性起重整片贝雷梁。 现场加固：每片贝雷架之间必须用配套连接件加固，保证贝雷架不位移，中间加以斜撑，防止倾覆。具体加固方法见附图。两端头及每隔3米必须加设一道剪刀撑。高空防护：为便于操作，同时作为高空防护用，在贝雷架上满铺不小于50mm厚木跳板。在贝雷架外边（PA、PB轴）为了上部扣件式满堂脚手架搭设时的安全防护，在贝雷架外边H型钢外挑长度1000m。外侧搭设双排脚手架，高度直至超出上部操作面1500mm。具体安装方法如下图所示。搭设扣件式模板支撑体系：在贝雷架上设置模板支撑的扣件式钢管脚手架，其间距为沿贝雷架长向为900mm（两头端部可作调整，但最大间距不得大于900mm），另一方向为贝雷架间距，横向按立杆间距设置水平杆，最上一步横杆距模板面板的距离不大于300mm.贝雷架的拆除：待顶板结构混凝土同条件养护试块强度满足设计要求后，先拆除脚手架及模板支撑，框架柱内侧贝雷架先拆除最里端一组，然后自内向外逐片搬运至内侧平台板上拆除，拆散后贝类片采用吊车直接吊到汽车上组织运输。 第五章、模板安装要求1模板应选用优质的胶合板，厚度15mm，木方初始截面尺寸不得小于4595。2梁模板安装应先复核标高，满足设计和规范要求后再铺设，安装后根据楼层上弹出的梁线进行平面位置的校正、固定。3应先将支撑体系搭设完毕经各方验收合格通过后再铺设梁底模及楼板，立杆尤其是梁下立杆严禁后加。对于梁高大于1000mm的，一般应先支一边侧模，另一边应在钢筋绑扎验收后再安装。4将加工成型的模板安装在支承架上，梁底模安装后应根据设计要求起拱。设计无要求时，起拱高度为全跨长度的1/10003/1000。5梁柱交接处、主次梁两交接处的模板可制作成U型卡板，以保证节点处的砼成型质量；楼板模板拼接的平整度、拼缝宽度必须满足验收规范要求，梁柱模板内空尺寸、轴线关系必须符合设计和质量验收规范要求。 第六章、模板拆除要求1、本工程梁、楼板跨度多为10.9米，从施工实际出发，所有底模必须待砼强度达到100%设计强度之后方可拆除。2、模板拆除前，应经项目工程师签发拆模令，任何人不得擅自拆除模板。并应组织操作人员进行书面安全技术交底。3、拆模应按先装后拆，后装先拆的程序进行，先拆除非承重部分，后拆除承重部分。4、柱、楼梯的承接模板应与上层模板同时拆除，保证连接的紧密性。 第七章、注意事项1、本工程模板支撑体系必须经相关部门验收合格后方可进行砼浇筑施工。2、模板施工严格按木工翻样的施工图进行拼装、就位和设支撑，模板安装就位后，由技术员、质量员按平面尺寸、标高、断面尺寸、垂直度进行复核验收。3、站台柱砼应提前浇筑，待柱砼强度过70%以上时高支模支撑系统必须与柱刚性连接后才可浇筑梁板砼。砼浇筑时应派人专门负责跟踪查模，发现异常情况应立即通知浇筑人员以便安全疏散，并视情况采取加固处理措施或撤离危险区。4、砼结构浇筑完成后，砼强度达到70%后方可拆除。5、浇注混凝土时应从中间向两头或两头向中间对称浇筑，严禁一个方向浇筑。6、作好安全技术交底，严格安全管理程序操作。 第八章、安全文明施工 现场材料布置由远及近依次设置板及板材配件、钢桁架件，各区设置明显标志牌，各种材料及半成品编号清晰明显，以防现场混乱，影响施工。 为防止材料、成品或半成品锈蚀，材料应堆放在仓库中；若现场没有仓库，则应搭设临时仓库，临时仓库地面应高出周围地坪；仓库应设专人看管，并建立相应的管理制度。 各种结构件及屋面材料堆放方式应尽可能接近安装后的支撑状况，以防止塑性变形。 施工现场的消防工作，应遵照国家有关法律、法规以及当地的防火规章规定开展消防安全工作。 工现场严禁吸烟。不得在建设工程内设置宿舍。 施工现场和生活区，未经保卫部门批准不得使用电热器具。严禁工程中明火保温施工及宿舍内明火取暖。严禁酗酒人员上架作业，施工操作时要求精力集中、禁止开玩笔和打闹。 Now, we are in a new historical stage of all-round construction of a well-off society. In perform duties, and carried out work of process in the, we to put people as a guide principles, and a test standard, efforts from masses most hope do of things do up, from masses most care of hot problem grabbed, from masses most not satisfaction of place modified up, not make nominal of formalism, not do grandstanding of cosmetic, to seeking of style, help masses share, is people benefit.
