一种用于高层建筑的安全连墙附着装置 技术领域
本发明涉及高层建筑施工领域，尤其涉及一种用于高层建筑的安全连墙附着装置。
背景技术
目前，高层或超高层建筑常用附着式升降脚手架作为建筑施工的安全防护和施工作业平台、常见的附着式升降脚手架一般为电动葫芦牵引式、液压提升式和手拉式等几种。
附着式升降脚手架由于安装速度快、施工效率高、安全可靠性好且不受建筑高度限制等诸多优势目前被广泛采用，具有显著的发展优势。在现有脚手架施工技术中，为配合可升降安全防护平台及导轨的安装，通常在建筑物外侧结构需安装多道附墙装置，将导轨或外脚手架主梁固定住并通过附墙支座传递的作用使作业平台产生升降的效果。
然而，脚手架防护平台在相对于附墙支座提升时，很容易出现因附墙支座设计或安装问题导致的提升不良现象，不仅影响外爬架的施工同时也危及到作业人员的安全。
另外在高层建筑施工过程中，还有其他安全使用的场景，在实际使用过程中，占用较大空间，不利于管理等。

实施例：
本安装系统基于该体系的螺杆力学特性验算过程如下：
根据设计说明，本系统安装采用英标(BS EN 14399)螺杆，螺杆一端承受内爬式设备的支撑架部分，另一端连接部分为分片提升式外爬架的附墙支座。
1、支撑架连接端：
通过设计计算已知，在极限状态下，该支撑架体系螺杆承受极限荷载(含可变荷载作用分项系数1.6)分别为：
在竖向力作用下，螺杆承受最大荷载为：Fv＝339KN×[1.6]＝543KN
在水平力作用下，螺杆承受最大荷载为：Fh＝89KN×[1.6]＝143KN
支撑体系合力点力臂＝200mm；
在竖向力作用下产生的弯矩为：Mv＝543KN×0.2m＝108.6KN·m
在水平力作用下产生的弯矩为：Mh＝143KN×0.2m＝28.6KN·m
该体系采用两组螺杆，每组两个，则每个螺杆受力分别为：
Pv＝108.6KN·m/(2nos×0.4m)＝136KN
Ph＝28.6KN·m/(2nos×0.3m)＝48KN
承受的总荷载为：136KN+48KN＝184KN
上述可知，单端螺杆承受的最大剪力为：S＝Fv/4＝543KN/4＝136KN
根据英标等级为8.8的M39螺杆设计要求，该螺杆设计抗拉强度为429KN，设计抗剪强度为358KN，则：
单端螺杆抗拉性能：429KN＞184KN(OK)
单端螺杆抗剪性能：358KN＞136KN(OK)
拉剪荷载组合系数＝184/429+136/358＝0.81＜1.4(OK)
2、支附墙支座连接端：
根据设计说明，该附墙支座承受荷载在极限状态下，简化为单一竖向荷载，该荷载取值为：
Fv＝32KN×[1.6]＝51.2KN
支撑体系合力点力臂＝500mm；
在该荷载作用下产生的弯矩为：Mv＝51.2KN×0.5m＝25.6KN·m
该体系采用两组螺杆，每组一个，单端螺杆承受的最大剪力为：
Pv＝25.6KN·m/(1nos×0.4m)＝64KN
单端螺杆抗剪性能：358KN＞32KN(OK)
3、该体系在螺杆双拉结状态下：
螺杆抗拉性能：429KN＞184KN(OK)
螺杆抗剪性能：358KN＞136+64KN＝200KN(OK)
拉剪荷载组合系数＝184/429+(136+64)/358＝0.99＜1.4(OK)
综上所述，螺杆两端受力特性均满足螺杆设计的安全性、可靠性设计要求。
如图17、图18所示，塔吊支撑装置包括与所述对拉螺杆连接的牛腿310，还包括与所述牛腿连接的主梁工字钢320，所述主梁工资钢上部连接有L形构件330，所述L形构件、主梁工字钢以及牛腿构成支承体系，所述主梁工资钢用于承接塔吊。
具体包括上端工字钢L形构件和下端牛腿支撑，上部L形连墙件由2根M30螺杆340(上螺杆)通过墙体预留孔固定在混凝土墙体上，螺母与外侧混凝土面交接位置增设16mm厚垫板，起到固定主梁的作用；为保证该连墙部分施工时因结构偏差导致预留孔洞出现偏位，造成的销轴同心度精度不够影响主梁螺杆与L型连接板连接，L形构件连墙端做了腰型孔优化，横向可调偏差保证孔位对接精准牢固，应力传递均匀。L形构件下端同样采用两根M30螺杆与356×406工字钢梁连接固定，该孔设计采用标准圆形孔尺寸。
L形构件与主梁工字钢相连，主梁工字钢支撑于下端牛腿上，下端牛腿部分则采用4根M39等级8.8螺杆通过墙体预留孔固定在混凝土墙体上，牛腿主体则采用610×305工字钢与30mm厚钢板焊接加工完成，并设置横向加劲肋，并通过4根M30等级8.8的螺杆配合双螺母设计与上方356×406工字钢主梁连接，形成连墙端部分的支承体系。
本装置采用的牛腿和上部工字钢通过螺杆连接并非附墙焊接工艺，一方面考虑应力传递的效果，另一方面则考虑到墙体浇筑阶段的位移偏差，因此，本装置在设计阶段将牛腿的上部与工字钢连接处做成纵向腰型孔以消除结构及安装偏差。
塔吊支撑装置结构简单，易于拆装，可标准化生产，可循环利用，且便于转移。该装置不仅区别于传统预埋式附墙连接装置的工艺复杂、预埋工作量大、连接误差不可调、预埋引发永久结构本身墙体构造变化、不可拆卸、后续收尾工作工序较多等相应弊端，能够在工艺创新的基础上减少物料用 量，提升钢材利用率，为项目降本增效，在工作效率和经济效益方面都有较为突出的成果。
上文所列出的一系列的详细说明仅仅是针对本发明的可行性实施方式的具体说明，它们并非用以限制本发明的保护范围，凡未脱离本发明技艺精神所作的等效实施方式或变更均应包含在本发明的保护范围之内。
