虹桥模板、大体积砼、预应力施工方案.doc

本工程基础模板除地下室中基础梁下沉部位、地下室筏板外侧模板均采用240厚实心砖砖胎模以处，其余均采用防水胶合板模板、木方背楞，钢管扣件支撑体系，配合采用槽钢柱箍、梁柱定型接头及对拉螺栓和工具式活动支撑。
１） 根据本工程结构形式、规模、层次、工期质量目标要求和我公司资源配备情况，考虑一次配足整个地下室施工所需的底板、墙板、顶板等构件所有的模板支撑体系，框架柱模板按各规格总柱数的1/2配备，施工中进行翻转使用。
２） 在施工过程中，对于每次拆除后的模板，要安排人员清理并检查，对于有破损的应及时更换，所有模板统一加工制作后应编号使用。
３） 针对本地下室工程创建筑优质结构的工程目标，我们在模板的投入上要下硬功夫，考虑所有模板均采用防水竹胶模板，其中槽钢柱箍和梁柱接头由专业厂家根据实际构件尺寸专门加工制作后送至现场安装。其余梁板模板由现场事先统一下料加工，并按照细木加工的要求进行模板制作。
４） 模板施工准备工作：
进行中心线和位置线的放线：首先用经纬仪引测建筑物的边柱墙轴线，并以该轴线为起点，测出每条轴线。模板放线时，应先清理好现场，然后根据施工图用墨线弹出模板的内外边线和中心线，墙模板要弹出模板的
In addition to this project based on the template the basement foundation beam subsidence area, outside of the basement raft template thick solid brick tiles are used 240 Die in office, the rest are used waterproof plywood templates, wooden flute back, steel fasteners support system, with channel columns with hoops, beam shape and bolt joints and tools support-type activities.
1) According to the project structure, scale, level, time requirements and quality goals with our resources and consider a full complement of construction required for the entire basement floor, wall, roof and other components all support system template, template columns according to the specifications of the total number of columns to 1 / 2, with construction carried out in turn to use.
2) During the construction process, for each time after removal of the template, to arrange for clean up and check for a damaged should be replaced, all templates should be uniform number to use after manufacture.
3) The record for building quality of the basement structure of the project objectives, we put in the template on to the next hard effort, consider all the templates templates are used waterproof glue bamboo, which channel coupling and beam column joints based on the actual components of professional manufacturers Size specifically sent to the scene after the installation of manufacture. The rest of the template from the site prior Beam under uniform material processing, and small wood processing in accordance with the requirements of the template production.
4) The template construction preparation:
To the center line and the location of the pay-off line: the first measured with theodolite cited the building wall side column axis, and to the axis starting point measured each axis. Template-off should be cleared before the scene, and then use the ink line drawings inside and outside the pop-up edges and center line of the template, the wall template to the pop-up templates
