办公楼是位于法院区内的办公建筑,是行政管理人员的工作场所。在设计上以规整的矩形安排平面,充分利用场地,合理划分功能分区。底层设大厅、传达室、配电室、资料室、档案室、各一个,办公室若干。二层设置办公室若干、大小会议室、会客室、活动室各一个。其它层设置办公室若干。每层设置男女厕所各一个,开水间两个。根据建筑防火等要求,力求交通路线简捷明确,联系通行方便,每层设置两道两跑楼梯,两台电梯。3.建筑方案本设计为八层办公楼,选用现浇式框架结构。总占地面积1265m2,总建筑面积7680m2,总高度为32.5m,层高3.9m。设计标高:室内设计标高±0.000,室外地坪标高-3.900。在立面设计中,主要强调建筑的简洁、典雅和亲和的特点,建筑形体采用弧形造型,不追求复杂的装饰,而是利用楼自身外墙材质塑造出色彩明快、富有动感的建筑形象。主出入口位于楼体正中,在入口台阶与雨蓬支柱间留有车辆停靠的空间,方便楼内工作人员下车后可快捷的进入楼内,也使立面效果更加有层次。办公楼屋面雨水通过柱内落水管排至室外地面。4.验算房屋高宽比及是否需要设伸缩缝房屋高度指室外地面至檐口高度,不包括局部突出屋面的水箱、电梯间等部分的高度,故本设计房屋高度为31.2米,房屋的宽度为21.5米。H/B=31.2/21.5=1.45<4符合要求现浇式框架结构室内的伸缩缝最大间距为55米,本设计中最长距离为53.2米,所以不需设伸缩缝。5.材料强度选择混凝土:1~8层柱:C301~8层梁、板:C30钢筋:梁、柱:主筋Ш级、其他Ⅰ级板:Ⅰ级17

第一节设计依据及要求一、设计依据1.工程设计使用年限:本工程设计使用年限为50年。2.自然条件:(1)基本风压:=0.40kN/m2。(2)地面粗糙程度:B类。(3)工程地质:根据河南省工程水文地质勘察院2003年12月提供的《新乡市郊区人民法院办公楼、审判厅岩土工程勘察报告》(详细勘察),本工程场地地形平坦,地貌属黄河冲积平原。场地内无活动断裂通过,无不良地质作用,但不良地质现象发育,属不均匀地基。场地覆盖层除上部填土外,属第四系地层。场地地震基本烈度为八度,场地液化等级为中等,场地土类型为中软场地土,场地类别为Ⅲ类,本工程场地类别按Ⅲ类进行结构设计。(4)水文概况:场地地下水属上层滞水类型。地下水稳定水位埋深5.4m,属孔隙潜水类型。场地地下水对混凝土无侵蚀性。17 二、设计要求1.本工程的建筑结构安全等级为二级,建筑抗震设防类别为丙类建筑。本次设计按八层考虑,抗震设防烈度为8度,设计地震分组为第一组,基本地震加速度值为0.70g。地震作用按8度验算,抗震措施按8度要求。现浇框架抗震等级为二级,自振周期折减系数0.6。2.设计荷载:活荷载标准值:地面2.0kN/m2走道、楼梯2.5kN/m2卫生间2.0kN/m2大开间办公4.0kN/m2设备间7.0kN/m2电梯机房7.0kN/m2上人屋面2.0kN/m2不上人屋面0.5kN/m23.设计规范及规程:《建筑结构可靠度设计统一标准》GB50068-2001《建筑结构荷载规范》GB50009-2001《混凝土结构设计规范》GB50010-2002《建筑地基基础设计规范》GB50007-2002《建筑抗震设计规范》GB50011-2001《钢筋焊接及验收规程》JGJ18-963 《建筑结构制图标准》GB/T50105-2001《建筑结构设计术语和符号标准》GB/T50085-20013 第二节结构方案一、结构选型由建筑方案可知,本工程为多层结构,建筑布置比较简单规则,为此本工程拟采用全现浇钢筋混凝土框架结构。二、基础形式由于天然地基不能满足要求,需对地基进行加固处理。根据《建筑地基处理规范》和建筑物特征及场地岩土工程特性,当采用复合地基时,本工程采用碎石桩与CFG桩组合复合地基,其中碎石桩(先施工)以消除液化为主要目的,而CFG桩(后施工)则是以提高地基强度为主要目的。碎石桩处理深度10.0-12.0米左右,CFG桩入土深度15米左右。依据勘察所做土工试验结果,若碎石桩有效桩长8.0-10.0米左右,桩径500mm,而CFG桩有效长13.0米左右,桩径400mm,均按正三角形(桩距1.3m)布桩,即在正三角形(碎石桩)的基础上,再在正三角形的中心布置CFG桩时,复合地基可达到≥250kpa。本设计在经CFG桩处理后的地基上做柱下独立基础,一条柱子下一个基础。三、主要材料1.混凝土强度等级基础垫层C15地梁C30柱C30梁C30楼层板C30屋顶板C30其它未注明混凝土强度等级不低于C25。3

截面选择高度不作绕度计算的最小高度,抗震要求,其取值还应符合模数和考虑门高度、构造、施工等因素对梁高的影响。一般按下式估算:梁高:框架主梁h≥(1/10~1/18)l,  次梁h≥(1/15~1/20)ll——梁的计算跨度梁宽:b=(1/2~1/3)h抗震要求梁应设计为长梁,梁的净跨度不宜小于截面高度的4倍。抗震要求框架结构的主梁截面宽度不应小于250mm,且不宜小于柱宽1/2,截面高度和宽度的比值不宜大于4。(1)KL1计算跨度,梁高取,初选;梁宽度,初选。按简支梁满载时的验算。取,则。选用HRB400,混凝土时,。按单筋梁估算,于是初选梁截面为。(2)KL2计算跨度,梁高取,初选;梁宽度,初选。(3)L1计算跨度,梁高取,初选3 ;梁宽度,初选。2.板厚尺寸选择按下述原则进行:l——板的较小计算跨度1/50×3800=76mm取现浇楼板厚100mm(顶层为120mm)。3.柱截面尺寸选择按下列原则进行:抗震要求柱截面宜采用正方形或接近正方形,在两个主轴刚度不宜相差太大,柱截面高度与宽度比小于1.5。框架柱截面不宜小于350mm,截面高度不宜小于400mm,柱截面沿房屋竖向变化次数不宜超过三次,上下柱最好均匀内收,即轴线对齐,避免偏心。同层框架柱截面不宜相差过大。地震区柱应设计为长柱,要求柱的净高与截面高度之比不宜小于4。地震区柱的截面尺寸应满足轴压比的要求。当未包括地震作用引起轴压力时,轴力乘以扩大系数1.2按下式估算:A≥1.2N/(αfc)式中:α:柱轴压比限值,抗震构造措施为一级时,α分别为0.7A:柱截面面积(mm2)fc:混凝土轴心抗压强度(N/mm2)N:荷载作用下柱子轴力,框架结构按12kN/m2估算N=12kN/m2×柱子受荷面积×计算截面以上层数×1.2(1)各层中柱3 按轴压比限值考虑。本结构框架抗震等级为一级,;办公楼荷载相对较小,取;楼层数;弯矩对中柱影响较小,取;;;柱负载面积;;;(1)各层边柱柱负载面积;取;其余参数与中柱相同;;;(3)考虑到各柱尺寸不宜相差太大以及柱抗侧移刚度应有一定保证,因此考虑扭转后初选柱截面尺寸为:中柱;边柱。以上尺寸也满足规范关于柱截面宽度和高度的最小尺寸、柱剪跨比、截面高宽比等要求。六、结构平面布置图具体详见图3-1,图3-2:3

具体调整见梁、柱配筋表。二、梁的截面设计1.梁的正截面强度计算:(1)最小配筋率的确定:因本工程为二级抗震,根据规范要求考虑强柱弱梁。梁采用C30混凝土,N/mm2,主要受力钢筋为HRB400,N/mm2,根据《混凝土结构设计规范》(GB50010-2002)11.3.6规定,二级抗震时,框架梁正截面设计抗震要求的最小配筋率支座取0.3%和%=65×1.57/300=0.34%的较大值,而跨中取0.25%和%=55×1.57/300=0.29%的较大值,所以支座取0.34%,跨中取0.29%。且梁端纵向受拉钢筋的配筋率不应大于2.5%。(2)翼缘宽度的计算:由于本设计方案采用现浇楼板,正截面受弯承载力计算时,在跨内正弯矩区段,板位于受压区,故按T形截面计算;在支座附近的负弯矩区段,板处于受拉区,故按矩形截面计算。按T形截面计算时,其翼缘的计算宽度按《混凝土结构设计规范》(GB50010-2002)表7.2.3规定,取各项中的最小值选用。(3)T形截面类型的判定:当时为第一类T形截面,否则为第二类T形截面,具体计算见表7-2。35

第一节施工方案一、施工总程序本工程总的施工程序是先地下后地上,先土建后设备安装,先结构后装饰,主体结构自下而上逐层分段流水施工,主体结构完工以后,自上而下逐层进行内装修,待女儿墙压顶完成后,自上而下进行外装饰。二、施工段的划分为了有利于结构的整体性,要尽量利用流水施工段的界限。主体工程每一层分两个施工段。屋面工程不分施工段,室内外装修工程不分施工段,室内装修自上而下分层进行,室外装修自上而下分立面进行。三、主要项目施工方法及施工顺序1.土方和基础工程1)施工顺序机械挖土→清底勘探→验槽处理→人工挖孔桩→混凝土垫层→基础→地圈梁→回填土2)本工程地下室部分土方采用WY-100型反铲土挖机配合自卸汽车进行基坑开挖。基坑底面按设计尺寸周边各留出0.5m宽的工作面,边坡放坡系数为1:0.33。开挖基槽后,坑槽底留30cm人工清底,以防机械超挖。基坑槽总的开挖土方量为3650立方米,除回填所需的649立方米暂时堆放在基坑槽边外,其余土方运至场外。3)为防止雨水倒流坑内,基坑上口筑小护堤。基坑和基槽两端各挖一个集水坑,并准备好污水泵。4)基坑清底后,随即进行勘探,并通知有关部门进行验槽。5)人工挖孔桩的每下挖1m土层即清理桩孔四壁,校核桩孔的垂直度和直径,6)然后支模,浇混凝土护壁,待达到一定强度时拆模,继续下挖。待开挖至地下14m时,进行扩大头施工。验收完毕后,排除孔底积水,放入串桶,浇灌桩身混凝土,待混凝土升至一定标高时放入钢筋笼架继续浇灌直至桩顶。7)基础墙内构造柱生根在地圈梁上。8)纵横墙内同时砌筑,接槎处斜槎到顶,基础大放脚两侧要均匀收,待砌到墙9)身时挂中线检查以放偏轴。10)基槽回填要两侧均匀下土,人工和蛙式打夯机分步夯实。35 四、主体结构工程1.结构工程中每层的主要施工顺序为:弹线→绑柱钢筋→柱支模→浇柱混凝土(在负一层柱上设置隔震装置)→支梁、板模→绑梁、板钢筋→浇筑梁、板混凝土。每层结构分两个施工段组织流水施工。2.楼西侧立QT1-6型塔吊。主体结构施工所需砖、混凝土、构件和周转材料的水平、垂直运输主要由此塔吊承担。同时在办公楼北侧设置两座扣井式井架,以弥补塔吊所安装不到的位置和缓解塔吊吊次,并作为垂直运输砂浆的主要工具,经验算,垂直运输能力满足要求。3.钢筋在车间加工好后,再运送至现场进行绑扎。绑扎采用22号铁丝,做到绑扎准确、牢固,同一截面中,绑扎接头的钢筋面积在受压区不得超过1/2,受拉区不得超过1/4,受力钢筋接头位置应相互错开。钢筋搭接长度取45d,搭接处应在中心和两端用铁丝扎牢。4.柱模板安装前,应先绑扎好钢筋,同时在楼面上弹出纵横轴线和四周边线,固定小方盘;然后立模,并用临时斜撑固定;再由顶部用垂球校正,检查出其标高位置无误后即用斜撑卡牢固定。其中,首层结构采用四面支撑。5.梁板支模在复核梁底标高、校正轴线位置无误后进行安装。安装板模板时,首先复核板底标高搭设模板支架,然后用阴角模板从四周与梁模板连接,再向中央铺设。为方便拆模,模板应在两端及接头处钉牢,中间尽量少钉或不钉。6.上一层结构梁板施工时,下一层梁板模板支柱不得拆除。拆模时,操作人员应站在安全处,以免发生安全事故。拆模过程中,如发现混凝土有影响结构安全的质量问题时,应暂停拆除,经过处理后,方可继续拆除。7.柱的混凝土浇筑采用人工浇筑,梁板的混凝土浇筑选用可移动液压式活塞混凝土泵,施工时由汽车带动混凝土泵在不同位置布管浇筑。8.柱子截面随建筑物的增高在地上第五层缩小截面一次,再在第九层缩小截面一次。在七层起混凝土标号由C40改至C30。五、砌筑工程1.砌砖采用一顺一顶法。在首层要做好排砖搭底,外墙大角要同时砌筑,内外墙接槎每步架留斜槎到顶,砌筑时控制灰缝厚度,不得超过支数杆灰缝高度。外墙为240墙,双面挂线,内墙为120墙单面挂线。2.二步架砌砖采用里脚手平台架子。3.35 用手推砖车和0.7立方米的砖笼直接把砖吊运到作业点,砌筑砂浆,用手推车通过井架运送。4.墙体砌筑时,内外墙尽量同时砌筑。当砖墙不能连通同时砌筑时,要留斜槎。5.为便于安装模板、绑扎钢筋和外装饰,外脚手架采用全封闭双钢管外脚手架,满挂安全网。施工脚手架要做好严格的安全防护,防止人员高空坠落事故及物体下落事故,确保市政道路、行人及工地施工人员的安全,并确保商业用房开业后的安全使用。六、屋面工程1.上人屋面为现浇混凝土板,待结构完工女儿墙压顶完成以后,上铺单层架空大阶砖隔热层。屋面找平层采用20厚水泥砂浆。2.防水层采用氯化聚乙烯橡胶卷材平行于屋脊铺贴,并用沥青灌缝,施工时应挂线。3.防水卷材的铺贴施工工序如下:底胶→卷材上胶→滚铺→上胶→复层卷材→着色剂七、楼地面和装修工程1.装修阶段主要用两座扣管式井作为垂直运输工具,每座井架配一台2吨卷扬机,水平运输用手推双轮车。2.楼地面装饰在主体结构完工后自上而下进行。3.其它楼地面和室内装饰的施工顺序立门窗口→墙面冲筋抹灰→清理地面→楼(地)面→楼(地)面养护→水泥墙裙、踢脚→安装门窗扇→安装玻璃→油漆、粉刷→灯具安装4.外墙装饰采用釉面瓷砖镶贴。镶贴前基层应清洁、湿润,基层刮糙后涂抹1:3水泥砂浆找平层,镶贴时按弹线和标志进行,墙面上弹好水平线并作好镶贴厚度标志,墙面的阴阳角、转角处均须拉垂直线,并进行兜方。贴釉面砖的施工顺序如下:清理基层表面→润湿→基层刮糙→底层找平划毛→出皮数杆→弹线→贴灰饼→镶贴釉面砖→清洁面层→勾缝→清洁面层5.门窗框一律采用后塞口,门窗框与交接处用水泥浆堵严。6.楼面基层清理、湿润后,先刷一遍素水泥浆作为结合层,然后抹水泥砂浆面层,铺锯末养护5—7昼夜。7.外墙装饰利用全封闭双钢管外脚手架,按自上而下的顺序进行。八、水暖、电气安装屋面板浇筑完毕以后,即插入安装下水漏斗及水落管;在室内抹灰之前埋好管道套管,并安装好线槽,安装好电线和盒座,避免二次剔洞反工。35
