国内超高层建筑施工普遍采用上海建工的整体爬升钢平台模架体系和中国建筑下属单位中建三局的大顶模模架体系,部分采用DOKA模架体系,但DOKA爬升模架系统平台有效承载不足,无法满足布料机的安装和施工材料堆码的要求。前两者的共同缺点是平台追求大而全,采用整体大平台加吊挂走道的方式,但最大的缺点是平台顶面到主要操作作业面的距离高,操作人员上下的作业效率不高,并且造成了钢结构吊装和钢筋绑扎作业面的操作空间狭窄,安装就位极为不便,对工效造成很大的影响。The construction of super high-rise buildings in China generally adopts the overall climbing steel platform formwork system of Shanghai Construction Engineering and the large top mold formwork system of the China Construction Third Subsidiary, and some adopt the DOKA formwork system, but the DOKA climbing formwork system platform is effective. Insufficient load bearing, unable to meet the requirements of the installation and construction material stacking of the distributor. The common shortcoming of the first two is that the platform pursues a large and complete approach, adopting the overall large platform plus hanging aisle, but the biggest disadvantage is that the distance from the top surface of the platform to the main operation surface is high, and the operation efficiency of the operator is not high, and The operation space of the steel structure hoisting and the steel bar tying work surface is narrow, and the installation is extremely inconvenient, which has a great influence on the work efficiency.
发明内容Summary of the invention
本发明所要解决的技术问题是现有超高层结构采用爬模或顶模单独进行施工,平台顶面到主要操作作业面的距离高,操作人员上下的作业效率不高,并且造成了钢结构吊装和钢筋绑扎作业面的操作空间狭窄,安装就位极为不便,对工效造成很大的影响,其目的在于提供一种可实现外模架和钢平台整体和局部顶升的液压顶升钢平台,这种钢平台通过设计为外爬内顶的方式,根据需要设定相应的连接操作方式,既保证施工的安全性,缩短了平台顶面到主要操作作业面的距离,提高了操作人员上下的作业效率;又增大了操作空间,使得钢结构和钢筋的安装就位非常方便,砼的浇筑可直接到达浇筑点,避免了大落差采用串筒浇筑砼的麻烦,极大地提高了工效,尤其适用于超高层建筑施工的使用。The technical problem to be solved by the invention is that the existing super high-rise structure is constructed by using a climbing mold or a top mold separately, the distance from the top surface of the platform to the main operation working surface is high, the operation efficiency of the upper and lower operators is not high, and the lifting of the steel structure is caused. The operation space of the steel bar tying work surface is narrow, the installation is extremely inconvenient, and the work efficiency is greatly affected. The purpose is to provide a hydraulic jacking steel platform capable of realizing the overall and partial lifting of the outer formwork and the steel platform. The steel platform is designed to externally climb the inner roof, and the corresponding connection operation mode is set according to the need, thereby ensuring the safety of the construction, shortening the distance from the top surface of the platform to the main operation working surface, and improving the upper and lower sides of the operator. The working efficiency; the operating space is increased, so that the installation of the steel structure and the steel bar is very convenient, and the pouring of the concrete can directly reach the pouring point, thereby avoiding the trouble of using the series pouring in the large drop, greatly improving the work efficiency, especially Suitable for the construction of super high-rise buildings.
本发明通过下述技术方案实现:The invention is achieved by the following technical solutions:
可实现外模架和钢平台整体和局部顶升的液压顶升钢平台,包括由若干个爬模单元依次围绕形成的立体结构的爬升系统,所述立体结构的内部设置有若干个并列设置的顶升单元构成的顶升系统,且爬升系统和顶升系统均能够进行竖直方向移动,且爬升系统和顶升系统之间形成用于钢结构和钢筋安装及浇筑混凝土墙体的空间。现有超高层建筑施工普遍分别采用的爬模或顶模模架两种体系,爬模体系可以实现局部顶升但有效承载不足,无法满足布料机和施工材料堆码的要求。顶模体系的缺点是平台追求大而全,采用整体大平台加吊挂走道方式,虽能满足承载的要求但是钢结构吊装和钢筋绑扎作业面的操作空间狭窄,安装就位极为 不便,工效提升受到极大的限制;并只能整体顶升,如果在施工中由于施工流水节点工作受阻,整个模架系统只有等待,无法进行下一步的工作,造成窝工现象。由于超高层建筑本身就是属于特殊建筑,对其进行施工的技术难度大,需要克服的困难多,施工人员由于技术、设备和资金的限制,无法将两种同时进行使用,都是只使用其中一种,而本方案采用外模架和钢平台组合的设计方法设计的超高层建筑施工顶模有效克服了以上的缺点,不但解决DOKA爬升模架系统布料机的安装和施工材料堆码不足的需求,还同时减少了平台和作业面距离,作业空间宽敞,钢结构和钢筋的安装一点不受影响,还同时可根据施工受阻流水节点部位来选择对应部位的外模架和钢平台继续配合受阻节点工作,而其余外模架和钢平台按照正常工作进行下一步顶升工作,且在顶升过程中不影响受阻节点工作面继续完成相应工作,达到不窝工,不影响工期的效果。A hydraulic jacking steel platform capable of integrally and partially lifting the outer formwork and the steel platform, comprising a three-dimensional structure climbing system formed by a plurality of climbing die units, wherein the three-dimensional structure is internally arranged with a plurality of juxtaposed The jacking system consists of a jacking unit, and both the climbing system and the jacking system are capable of vertical movement, and a space for the steel structure and the steel bar to install and pour the concrete wall is formed between the climbing system and the jacking system. The existing super-high-rise building construction generally adopts two systems of climbing mold or top mold formwork. The climbing mold system can achieve partial jacking but insufficient effective bearing, and cannot meet the requirements of the stacking machine and construction material stacking code. The disadvantage of the top mold system is that the platform pursues a large and complete approach. The overall large platform and the hanging walkway are adopted. Although the load bearing requirements can be met, the operation space of the steel structure lifting and the steel bar binding work surface is narrow, the installation is extremely inconvenient, and the work efficiency is improved. Great limit; and can only be lifted as a whole. If the construction flow node is blocked during construction, the entire formwork system will only wait and cannot carry out the next work, resulting in a work-in-the-work phenomenon. Since the super high-rise building itself is a special building, the technical construction of it is difficult, and there are many difficulties to be overcome. Due to the limitations of technology, equipment and funds, the construction workers cannot use the two at the same time, and only use one of them. The super high-rise building top mold designed by the design method of the outer mold frame and the steel platform combination effectively overcomes the above shortcomings, and not only solves the problem of insufficient installation and construction material stacking of the DOKA climbing formwork system. At the same time, the distance between the platform and the working surface is reduced, the working space is spacious, and the installation of the steel structure and the steel bar is not affected at the same time. At the same time, the outer mold frame and the steel platform of the corresponding part can be selected according to the blocked portion of the construction flow to continue to cooperate with the blocked node. Work, while the rest of the outer formwork and the steel platform carry out the next lifting work according to the normal work, and in the process of jacking, the work surface of the blocked node is not affected to continue the corresponding work, and the work is not completed, and the effect of the construction period is not affected.

A space for the steel structure and the steel bar to install and pour the concrete wall is formed between the climbing module unit and the adjacent jacking unit, so that it is more convenient when the concrete is poured, which shortens the top surface of the platform. The distance to the main operation surface is higher, and the operation efficiency of the operator is higher and higher, and the operation space is increased, which makes the installation in place very convenient and greatly improves the work efficiency.
为了便于通行,在爬模单元和靠近的顶升单元之间、相邻的顶升单元之间搭设有通道板,这属于临时板,在需要同时顶升时通道板不撤销,要单独顶升或对应顶升时,将通道板撤开,根据需要再对应安装。In order to facilitate the passage, a channel plate is arranged between the climbing module unit and the adjacent jacking unit and the adjacent jacking unit. This is a temporary plate. When the jacking is required, the channel plate is not revoked. Or when corresponding to the jacking, remove the channel board and install it as needed.

The wind is large, there is a big safety hazard. In order to ensure its safety, it is necessary to further increase the lifting force, so that the cylinder required for jacking is high, and a special custom-made jacking cylinder and jacking system are required. The lift cylinder and jacking system can only be applied to the project and the construction site.

本发明的设计采用逆向思维,首先按照市场上普遍采用的成熟可靠的顶升油缸的最大承载力F来确定支撑点的个数n(n=P/F,P-单元总荷载)。以南宁华润东写字楼为例:核心筒分六个模块,最大模块单元的自重为100吨,各种活荷载80吨,取用最不利的效应设计值为240吨,目前市场上普遍采用的成熟可靠的顶升油缸的最大承载力为80吨(缸径150MM),支撑点个数n=240/80=3,每一模块采用为4个顶升油缸。The design of the present invention adopts a reverse thinking, first determining the number n of support points (n=P/F, P-unit total load) according to the maximum bearing capacity F of a mature and reliable jacking cylinder commonly used in the market. Take the Huarun East office building in Nanning as an example: the core tube is divided into six modules, the maximum module unit has a deadweight of 100 tons, various live loads of 80 tons, and the most unfavorable effect design value is 240 tons, which is currently widely used in the market. The maximum capacity of the reliable jacking cylinder is 80 tons (150MM bore), the number of support points is n=240/80=3, and each module adopts 4 jacking cylinders.
控制系统也采用同样的设计思路选取市场最成熟可靠的液压控制系统(系统的额定压力p满足油缸最大承载力F的要求,p=F/S,S-油缸面积)以南宁华润东写字楼为例:系统需要的额定压力为:p=800000/70650=11.4Mpa,根据市场供货可有系统压力15Mpa、20Mpa、25Mpa、30Mpa、35Mpa等供选择,根据经济比较选取额定压力25MPA的系统,既能保证足够的富裕和安全又有很好的经济性。The control system also adopts the same design idea to select the most mature and reliable hydraulic control system in the market (the rated pressure p of the system meets the requirements of the maximum bearing capacity F of the cylinder, p=F/S, S-cylinder area), taking the Huarun East office building in Nanning as an example. : The rated pressure required by the system is: p=800000/70650=11.4Mpa. According to the market supply, there are system pressures of 15Mpa, 20Mpa, 25Mpa, 30Mpa, 35Mpa, etc. According to the economic comparison, the system with rated pressure of 25MPA can be used. Ensuring sufficient wealth and security is also very economical.
支撑油缸的结构设计采用40号槽钢组合的型钢桁架结构,制造简单,受力明晰、可靠,既保证了受力的强度要求又具有很好的稳定性。同时油缸置于双槽钢中间,便于对油缸的保护,在工作状态或转运时不会因为意外对油缸造成碰撞损害。The structural design of the supporting cylinder adopts the steel truss structure of the 40-channel steel combination, which is simple in manufacture, clear and reliable, and ensures the strength requirement of the force and has good stability. At the same time, the cylinder is placed in the middle of the double channel steel to facilitate the protection of the cylinder, and it will not cause collision damage to the cylinder due to accidents during working or transportation.
油缸和油缸承载结构基本模数采用3米高度,使整个系统满足几乎所有高层建筑的施工要求,具体的针对性项目标准层高按照优先数系原则加高(比如南宁华润东写字楼设计为总高度为5米),使所有结构件和主要液压件能最大限度提高利用率。The basic modulus of the cylinder and cylinder load-bearing structure adopts a height of 3 meters, so that the whole system can meet the construction requirements of almost all high-rise buildings. The specific layer height of specific targeted projects is increased according to the principle of priority number (for example, the design height of the Nanning China Resources East office building is the total height) 5 m), maximizing utilization of all structural components and main hydraulic components.
油缸与支撑结构的连接采用销轴连接,便于提高安装拆卸的效率,还在油缸的承载结构在顶部开有一个方形孔洞,为由于意外情况油缸更换留有更换空间,便于意外损坏情况发生时对油缸更换,不影响施工工期。The connection between the cylinder and the support structure is connected by a pin shaft, which is convenient for improving the efficiency of installation and disassembly.

第二步:拆除上支撑架与建筑连接的两个10.9级M36的高强度螺栓,再次确认各顶升部 位与建筑无干涉。Step 2: Remove the two 10.9-class M36 high-strength bolts that connect the upper support frame to the building and reconfirm that the jacking positions do not interfere with the building.
第三步:开动系统按照要求进行顶升作业,同时注意观察系统压力及电气有无异常,直到上支撑架和整个架体到达下一连接部位停止。The third step: start the system to carry out the jacking operation as required, and pay attention to observe the system pressure and electrical abnormalities until the upper support frame and the entire frame reach the next connection site to stop.
第四步:连接好上支撑架的两个10.9级M36高强螺栓,检查所有连接好后,拆除下支撑架的两个10.9级M36高强螺栓,开动顶升油缸收缩至下一层的连接位置,到位后连接好两个10.9级M36高强螺栓,完成一个标准层的顶升工作。Step 4: Connect the two 10.9 M36 high-strength bolts on the upper support frame. After checking all the connections, remove the two 10.9-class M36 high-strength bolts of the lower support frame and start the expansion of the jack-up cylinder to the connection position of the next layer. After the position, connect two 10.9 M36 high-strength bolts to complete the lifting of a standard layer.
本方案采用的油缸为通用压力和缸径的普通油缸,全是标准的液压元器件,使任一原件维护保养和更换相当方便,加上特殊的结构构造设计,万一遇到油缸故障而不便维修时可以马上用自有的任一油缸很方便地进行更换并完成顶升作业,进度影响最小,其由于逆向的设计思路,超高层施工完成所有部件均可用于普通高层建筑施工,利用率达到最大化。而且对建筑结构没有特殊要求,施工完成对建筑结构不留下任何影响。对所有顶升系统支撑结构在保证安全和可靠性前提下进行标准化和优化设计使自重最轻,操作简便,功效高并实现经济性最好。The cylinder used in this scheme is a common cylinder with universal pressure and bore diameter. All of them are standard hydraulic components, which makes it convenient to maintain and replace any original parts. With special structural design, it is inconvenient to repair if it encounters cylinder failure. It can be easily replaced with any of its own cylinders and complete the jacking operation. The progress of the project is minimal. Due to the reverse design, all the components of the super high-rise construction can be used for ordinary high-rise building construction, and the utilization rate is maximized. Chemical. Moreover, there is no special requirement for the building structure, and construction completion does not leave any impact on the building structure. Standardization and optimization of all jacking system support structures under the premise of ensuring safety and reliability make the self-weight the lightest, easy to operate, high efficiency and economical.
超高层建筑核心筒施工模架体系核心筒外部施工及防护采用爬模,核心筒内部施工及防护采用钢平台顶升的方式,即简称为内顶外爬(或外爬内顶)模架体系,既可整体同时爬升和顶升,也可以根据施工流水进度安排分别独立爬升和顶升;兼具爬模的灵活性又具有顶模的高承载能力,并有效解决了针对超高层建筑施工中经常遇到的局部施工流水节点受阻现象,传统模架系统只有等受阻节点工作完成才能进行下一步工作,造成窝工和工期滞后现象;特别是针对超高层建筑施工中通过伸臂桁架层施工时很好的解决爬升干涉问题,有效避免通过伸臂桁架层施工降效的问题。The super-high-rise building core tube construction formwork system core tube external construction and protection adopts climbing mold, the core tube internal construction and protection adopts the steel platform jacking method, which is referred to as the inner top outer climbing (or outer climbing inner top) formwork system. It can climb and ascend at the same time as a whole, and can also independently climb and ascend according to the schedule of construction flow; it has the flexibility of climbing mold and the high bearing capacity of the top mold, and effectively solves the problem of super high-rise building construction. Frequently encountered local construction flow nodes are blocked. The traditional formwork system can only carry out the next step when the work of the blocked nodes is completed, which causes the work and construction period to lag; especially for the construction of the overhang truss layer during the construction of super high-rise buildings.
