[来源:www.futejixie.com] [作者:aoutmy] [日期:17-05-04]

某市超高层电信枢纽大楼工程框剪结构,总建筑面积33400 m2,地下二层,地上十八层。层高4.5m,总高84m.主体框架及剪力墙采用导轨式电动整体爬架(模)体系,剪力墙施工使用电动爬架带动钢制大模板整体同步提升,施工先进,效果良好。“导轨式电动整体外爬架(爬模) 施工技术”评为省级工法,此项工程批准为全国建筑业新技术推广应用示范工程,2005年由建设部组织专家组验收通过。 The construction area of a high level telecommunication hub in the city is 33,400 m2, the floor of the ground floor, and the ground floor is 18 floors. The height of 4.5 m, the total is 84 m. high body frame and shear wall using guide rail type electric integrated climb (die) system, shear wall construction using electric drive steel template as synchronous upgrade, climb the construction is advanced, the effect is good. "Outside the guide rail type electric integrated frame (climbing form construction technology of" provincial method, the project approved by the national construction industry new technology application demonstration projects, 2005 by the ministry of construction organization expert group acceptance through.   一、超高层框剪结构导轨式电动整体爬架、爬模 One, super tall frame shear structure guide rail type electric whole climbing frame, climbing model   1)方案特点: 1) scheme features:   超高层框剪结构如按常规采用搭设双排脚手架或三角架支撑系统作为工作面支设大模板,这些方法效率低,安全性差,劳动强度高,为了解决这一问题我们采用了导轨式电动整体提升爬模工艺,以附墙导轨为依托,架体上悬挂可调大模板,电动同步升降。此技术整体性好,安全可靠,劳动强度低,工效高, High-rise frame shear structure such as conventional set-up double-row scaffold or using a tripod as for working face big template support system, the method is of low efficiency and poor safety, high labor intensity, in order to solve this problem we have adopted the ascent climbing form guide rail type electric technology, based on attached guide, body hang adjustable template, lifting electric synchronization. This technology is integrated, safe and reliable, with low labor intensity and high efficiency.   ①同一附着点多层多点附墙,保证整体牢靠稳定。 The same attachment points with multiple layers of wall, ensuring the overall stability.   ②具备防外倾及导向功能,整体受环境因素影响小。 It has the anti-leaning and guiding function, and the whole environment is affected by the environment.   ③爬架一次安装,多次进行循环升降,操作简单,工效高,速度快,成本低。 The mount is mounted once and has been repeatedly raised and raised, the operation is simple, the efficiency is high, the speed is fast, the cost is low.   ④按施工流水段进行分段分单元升降,以便于流水交叉作业。 The section of the section is divided by the section of the construction flow, so as to cross the flow of water.   ⑤爬模架体能够悬吊大模板同步爬升,(无须用塔吊吊装大模板),利用手动葫芦悬挂大模板便于大模板合模及拆模;利用大模板水平旋转支撑,便于临时找正加固。 (5) climbing formwork synchronous climb to suspension template, (no need to use crane hoisting large template), using manual gourds hanging big template to the template clamping and dismantle; Using the horizontal rotating support of large template, it is easy to find positive reinforcement.   2)工艺原理 2) process principle   在建筑结构四周分布爬升机构,附着装置安装于建筑结构上,架体利用导轮组攀附安装于附着装置的导轨外侧,电动葫芦通过提升挂座固定安装在导轨上,提升钢丝绳悬吊住提升滑轮组件,实现架体依靠导轮组沿导轨上下相对运动,架体上部设悬挑支架及升降手动设备悬挂大模板,调整大模板左右、上下空间位置,用于支模、拆模。 Climb around the building structure distribution agencies, attachment of installation on the building structure, frame body use the idler pulley group clings to install in the attachment of guide rail lateral, electric hoist through ascension fixed hanging seat is installed on the guide rail, the hoisting cable suspension live ascension block and tackle, realize on the rack body relative movement up and down the guide rail, idler pulley group upper frame body set cantilever bracket and manual lifting equipment hung big template, adjust around big template, the space position, used in the mold, mold.   3)爬架组装工艺设计要点 3) the main points of the climbing assembly process   ①平面设计:考虑爬架(模)整体平面,主框架水平分段、分块的布局,预埋点及导轨的平面位置,爬架内排立杆离墙距离,立杆距离。 (1) the plane design: consider climb frame (die) integral plane, the layout of the main frame of horizontal section, block, embedded point and guide plane position, climbing frame in vertical pole distance away from the wall, vertical pole distance.   ②立面设计:主要考虑立面整体高度,主框架及架体的竖向尺寸及分层步数,卸荷点及绳索连接点构造及尺寸,导轨的加强支撑构造,导轨附墙与架体的连结构造,架体悬挂大模板在施工中的安拆空间尺度要求。 (2) the facade design, main consideration facade overall height, the vertical dimension of the main frame and the frame body and stratified steps, unloading point and rope connection structure and size, the strengthening of guide rail support structure, guide rail links attached to the wall and the frame body structure, the frame body suspension and dismantling of large formwork in the construction of the space dimension requirement.   ③安全防护设计:每层脚手板铺设,平网、立网的整体全封闭围护,靠墙翻板构造节点,与墙体间隙的防护及防火防触电。 (3) safety protection design: each floor planks laid, flat screen, set net overall closed enclosure, node structure, turning against the wall and wall body clearance protection and fire prevention of electric shock.   ④预留预埋设计:主要考虑预留孔预埋件的平面位置及立面标高的确定和控制方法。 Pre-buried design: mainly consider the plane position of the reserved hole and the determination and control method of elevation elevation.   ⑤电气设计:主要考虑架体整体同步和分段、分块单体调节升降控制线路,总控制台及分控点传感及通讯,以及防雷安全接地等。 (5) electrical design, main consideration frame synchronization and whole body block, block monomer adjust elevator control circuit, general control and sensing and communication control points, and lightning protection grounding safety.   4)工艺流程分(1)爬架初爬升流程,(2)大模板施工工艺流程 4) process flow (1) climb the initial climbing process, (2) the great template construction process
