13、请经技术部门批准后方可拆除。 (3)预应力混凝土结构构件模板的拆除,除执行GB50204中2.4.1或2.4.2条的规定外,侧模应在预应力张拉前拆除;底模应在结构构件建立预应力后拆除。 (4)已拆除模板及支架的结构,在混凝土达到设计强度等级后方允许承受全部使用荷载;当施工荷载所产生的效应比使用荷载的效应更不利时,必须经核算,加设临时支撑。 (5)拆除模板的顺序和方法,应按照配板设计的规定进行。若无设计规定时,应遵循先支后拆,后支先拆;先拆不承重的模板,后拆承重部分的模板;自上而下,支架先拆侧向支撑,后拆竖向支撑等原则。 (6)模板工程作业组织,应遵循支模与拆模统由一个作业班组执行作业。其好处是

14、,支模就考虑拆模的方便与安全,拆模时,人员熟知,依照拆摸关键点位,对拆模进度、安全、模板及配件的保护都有利。2、柱子模板拆除: (1)工艺流程:拆除拉杆或斜撑 自上而下拆除柱箍 拆除部分竖肋 模板及配件运输维护 (2)柱模板拆除时,要从上口向外侧轻击和轻撬,使模板松动,要适当加设临时支撑。以防柱子模板倾倒伤人。 3、梁板模板拆除(1)工艺流程 拆除支架部分水平拉杆 拆除侧模板 下调楼板支柱 使模板下降 分段分片拆除楼板模板 木龙骨及支柱 拆除梁底模板及支撑系统 (2)拆除工艺施工要点: 拆除支架部分水平拉杆和剪刀撑,以便作业。而后拆除梁侧模板上的水平钢管及斜支撑,轻撬梁侧模板,使之与混凝土表面

15、脱离。 下调支柱顶翼托螺杆后,轻撬模板下的龙骨,使龙骨与模板分离,或用木锤轻击,拆下第一块,然后逐块逐段拆除。切不可用钢棍或铁锤猛击乱撬。每块竹胶板拆下时,或用人工托扶放于地上,或将支柱顶翼托螺杆在下调相当高度,以托住拆下的模板。严禁模板自由坠落于地面。拆除梁底模板的方法大致与楼板模板相同。但拆除跨度较大的梁底模板时,应从跨中开始下调支柱顶翼托螺杆,然后向两端逐根下调,拆除梁底模支柱时,亦从跨中向两端作业。(3)底模及其支架拆除时,混凝土强度要符合下表规定:构件类型构件跨度(m)达到设计的混凝土立方体抗压强度标准值的百分率(%)板2m502跨度8758100梁8758100悬臂构件-100模板

16、拆除时必须根据结构构件的同条件混凝土试块的强度指标来确定拆模时间。具体拆模日期由项目技术人员书面通知,没有书面通知不得擅自进行拆模施工。模板及其支撑体系拆除时,严格按施工工艺和技术交底执行,以防发生意外事故,严禁违章操作。拆模前填写拆模申请单,经主管技术人员和试验部门、质量部门同意后方可拆除。(六)成品保护1、预组拼的模板要有存放场地,场地要平整夯实。模板平放时,要有木方垫架。立放时,要搭设分类模板架,模板触地处要垫木方,以此保证模板不扭曲不变形。不可乱堆乱放或在组拼的模板上堆放分散模板和配件。2、拆除模板时,不得用大锤、撬棍硬砸猛撬,以免混凝土的外形和内部受到损伤。(七)应注意的质量问题1、

17、梁、板模板:梁、板底不平、下挠;梁侧模板不平直;粱上下口模;防治的方法是,梁、板底模板的龙骨、支柱的截面尺寸及间距应通过设计计算决定,使模板的支撑系统有足够的强度和刚度。作业中应认真执行设计要求,以防止混凝土浇筑时模板变形。模板支柱应立在垫有通长木板的坚实的地面上,防止支柱下沉,使梁、板产生下挠。梁、板模板应按设计或规范起拱。梁模板上下口应设销口楞,再进行侧向支撑,以保证上下口模板不变形。起拱方法:支梁板模板时均跨下起拱,支好模板后再从中间起拱到要求的梁板底标高,起拱应由班组长、放线员、专业工长严格控制,不但要保证起拱高度,还要保证梁的高度和板的厚度。跨度大于4m的框架梁,按全跨长度3进行梁底

18、模起拱;跨度大于3.6m的板按全跨长度3进行起拱,起拱从支模开始时进行(通过增加木楔调整底模各部位标高),而后将侧模和底模连成整体。严格控制顶板模的平整度,两块多层板的高低差不大于1mm。主木楞100100mm,次木楞50100mm(立),木楞平直,过刨使其薄厚尺寸一致。当多层板铺于木楞上接茬处高低超过1mm时,应在木楞上加海绵条垫平。梁、板、柱头交接处,阴阳角、模板拼接处要严密,模板边要用手电刨刨齐整,拼缝不超过1mm,并且,在板缝底下必须加木楞支顶。梁、柱头阳角处,梁、柱头、顶板等模板交接处加海绵条。2、柱模板(1)涨模、断面尺寸不准:防治的方法是,根据柱高和断面尺寸设计核算柱箍自身的截面

19、尺寸和间距,以及对大断面柱使用穿柱螺栓和竖向钢楞,以保证柱模的强度、刚度足以抵抗混凝土的侧压力。施工应认真按设计要求作业。 (2)柱身扭向:防治的方法是,支模前先校正柱筋,使其首先不扭向。安装斜撑(或拉锚),吊线找垂直时,相邻两片柱模从上端每面吊两点,使线坠到地面,线坠所示两点到柱位置线距离均相等,即使柱模不扭向。 (3)轴线位移,一排柱不在同一直线上:防治的方法是,成排的柱子,支模前要在地面上弹出柱轴线及轴边通线,然后分别弹出每柱的另一个方向轴线,再确定柱的另两条边线。支模时,先立两端柱模,校正垂直与位置无误后,柱模顶拉通线,再支中间各柱模板。柱距不大时,通排支设水平拉杆及剪刀撑,柱距较大时

20、,每柱分别四面支撑,保证每柱垂直和位置正确。审核人交底人接受交底人1、本表施工单位填写,交底单位与被交底单位各存一份。2、当分项工程施工技术交底时,应填写分项工程名称,其他交底可不填。155(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
