@trustevil, today it's maybe only a few meters higher and You think is the core already topped out ?
Then "jewel/diamond crown" height should have about 50m

汽车行驶在滨海高新区津静公路上,远远望去可以看到117大厦高挑纤细的身姿。“危楼高百尺,手可摘星辰。不敢高声语,恐惊天上人。”这原本是古代诗人瑰丽的想象,如今的建设者正在将这美丽的诗文变为现实。就在津静公路与海泰南北大街交口处,117大厦成为世界第8座、中国第5座、中国北方第一座超过500米的摩天大楼。日前,记者探访了这个“中国结构第一高楼”,记录下它成长的秘密。

   117大厦:中国结构第一高楼

  5月31日,中国北方之巅再次升高!由中建三局承建的117大厦主塔楼第113层混凝土浇筑顺利完成,目前核心筒结构标为553.095米,117大厦突破550米,高度早已超越总高度为541米的美国最高建筑——世贸大厦一号楼,也超越了420.5米的上海金茂大厦、440米的广州西塔、441.8米的京基100、451.9米的吉隆坡双子塔、492米的上海环球金融中心、509米的台北101大厦、539米的广州东塔等国内外知名建筑。

  登上500多米的顶升模架钢平台,津城天际线一览无遗,天津广播电视塔被踩在脚下,一架架飞机从头顶掠过。据117大厦项目部执行总经理侯玉杰介绍,117大厦主塔楼将于今年下半年实现结构封顶,届时将以597米的檐口高度成为中国结构第一高楼。

  筑梦云端,圆梦津门。在不久的将来,以天津117大厦为核心的高银金融中央商务区将成为天津全新商务区,更将成为中国京津地区的全新地标和天津市的靓丽“名片”。

   这么高的楼,人、机、料怎么进入施工场地?

  通道塔电梯:500多米高的运输主动脉

  记者坐上通道塔电梯,大约10多分钟后,到达了500多米高空。途中,随着电梯逐渐攀升到楼顶,天津风光尽收眼底。据了解,一般中速施工电梯的速度为每分钟50米,而通道塔电梯最高速度可达90米。打开安全门,一条宽5米的通道搭接在主塔楼各层楼面上。如果说通道塔是运输主动脉,那么连接通道就是毛细血管,人、机、料最终由这里进入大楼。

  垂直运输是超高层摩天大楼施工的一大难题。天津117大厦主塔楼需混凝土19.1万立方米、钢筋4万吨、钢构件14.3万吨,高峰期施工人员多达2500余人,垂直运输压力巨大,大量的建筑材料、施工垃圾和作业人员都靠“华山一条路”——施工电梯。

  为此,项目在中国内地率先研发通道塔技术,采取“工厂预制、现场拼装、整体吊装”的流水作业,装配效率极高,后期拆除也很方便。该通道塔平面尺寸为5米×9米,一面与主楼相连,另外三面附着5部双笼施工电梯,统一调度指挥,实现“人货分离、分层停靠、分时上下”,极大提高了运输效率。

  这么大的工程,“蹿个儿”怎么这么快?

  顶升模架:“金刚罩”让大厦6天长一层

  在大厦的顶端,一座高20米左右的“金刚罩”包裹着大楼核心筒顶部,仿佛一座“空中楼阁”横亘云端。117大厦没有像一般建筑物那样搭设脚手架,“长高”的秘密就在“金刚罩”这里。

  中建三局117项目部总工程师余地华解释说,这个“金刚罩”是全国面积最大的核心筒顶升模架系统——“模块化低位顶升钢平台模架系统”,由钢平台、挂架系统、液压支撑系统、模板系统、防护系统、安全监测系统组成。

  顶模这个“大盒子”,长35米、宽32米、最大高度21米、重约1100吨,有4层楼高,可同时进行3层核心筒立体施工,实现流水作业、无缝对接。该系统将随117大厦主塔楼顶推至597米高空,创“中国北方第一顶”。

  钢平台每平方米最大承重1吨,可放置机械设备、建筑材料等,成为一个偌大的“空中堆场”。此外,平台上还配有液压系统控制室、设备房、休息室和卫生间,可供施工人员休息使用。挂架系统是工人作业平台,采用镀锌钢板网全封闭,杜绝了高空坠落的危险。4个大行程液压油缸是整个模架顶升的引擎,通过4根钢立柱撑住整个模架系统,立柱高达19米,扩大了立体施工的楼层数,破解了超高层核心筒结构快速施工难题。为了保证模架系统更加安全有效运行,中建三局对模架主要杆件进行应力监测,可有效掌控模架的“身体状态”,确保模架使用安全。

  2013年3月24日,117项目顶模系统第一次顶升成功。由方圣锋“领衔”的5人顶模小组,1人常驻操控室,其余4人每人负责一个液压千斤顶,相互配合。如果遇到大风,塔吊电梯将全部停运。顶模小组曾多次因大风被困在顶模平台,一困就是两三个小时,无法下来就餐,只得通过塔吊将盒饭吊至平台,热腾腾的饭菜吊上来后就冷冰冰了。“虽然工作辛苦点,但是一想到项目这么多人中只有我们5人才能操控国内最大的顶模系统,自豪感便油然而生。”方圣锋对记者说。

117大厦干嘛用?
  商务区核心建筑:含办公楼及六星级酒店
  天津117大厦,地下4层,地上117层,高597米,总建筑面积84.7万平方米,创摩天大楼建筑面积世界之最,系一幢集甲级办公、酒店、旅游观光和精品商业于一体的特大型超高层摩天大楼。大厦首层65米×65米,建筑面积4200平方米,向上以0.88度的角度逐层缩小,顶层46米×46米,建筑面积2100平方米。
  117大厦建筑设计融合了中国传统文化与现代美学,是高银中央商务区的核心建筑,该商务区还设有精品商业、金融企业总部大楼、双子塔办公大楼、会展中心、服务式公寓、高端高层住宅与别墅,总长达338米的商业廊将117大厦和金融企业总部大楼连通起来,6个钻石造型圆厅成为商业廊的入口,与117大厦主塔楼钻石顶造型遥相呼应,精巧别致。
  天津117大厦项目常务副总经理李干椿介绍,大厦内设有甲级国际水平办公楼及六星级酒店。甲级办公楼目标租户及客户为跨国公司和国际企业。94层至104层的六星级酒店将引进迪拜帆船酒店的建造标准,大厦在115层、564米处设有豪华游泳池,将创造一项新的世界纪录,成为世界最高的室内泳池。
  大厦还将在116层的夹层处设置世界最高的观光厅,位于钻石造型内部,高度为579米,它将打破由上海环球金融中心在2009年创造的474米“世界最高观光厅”吉尼斯世界纪录,成为世界最高观光厅,在那里,天津城市天际线将尽收眼底。
  大厦选址地质结构复杂咋办?
  “骨架”倍儿硬朗:近千根长桩筑牢根基
  117大厦所在地地层结构复杂,是以粉砂、粉土和粉质黏土为主的海相与陆相交互沉积地层,为使工程桩稳固支撑117大厦,设计了941根120米长桩作为大厦的基础,创造了房建领域工程桩长度之最。直径为1米的百米长桩穿越5个相对含水层,在复杂的地质环境下要保证工程桩的垂直度不大于1/300、保证不塌孔、保证孔底沉渣厚度小于10厘米、保证工程桩钢筋笼的混凝土保护层厚度以及工程桩混凝土的水下浇筑顺利,这是非常艰巨的挑战。
  中建三局综合在上海、武汉等临海临江地区的深基坑施工经验,结合天津地区的地质情况精心编制了超长桩施工技术方案。选用ZSD2000、GPS-20等多种型号的钻机,采用气举反循环工艺和深厚沙土超深钻孔泥浆控制技术进行120米超长桩试桩施工。通过不断调整泥浆比重和成孔钻进速度等技术参数,最终确定了可靠的长桩施工方案,并成功攻克了垂直度控制小于1/300的世界性难关,经检测全部达到一类桩标准。941根长桩与65000立方米大底板筑牢了大厦的根基。
  超高层摩天大楼嘛结构,结实吗?
   钢结构加混凝土:巨型框架构筑坚实“脊梁”
  117大厦结构设计采用“钢筋混凝土核心筒+巨型框架”的结构体系,是目前最为科学的超高层摩天大楼设计形式。由于超高层建筑太重不经济、太轻又不稳,所以400米以上高楼一般不会采用纯钢结构,而是采用钢结构加混凝土相结合的形式。4根巨型柱、8根国内最大的防屈曲支撑、9道环带桁架、8道巨型斜撑等共计15.3万吨钢构件共同构成主楼坚实的“脊梁”。
  巨型柱分布在塔楼的四个角,单根截面尺寸最大处为45平方米,创超高层巨型柱截面尺寸世界之最。巨型柱呈六边菱形,内部由26个腔体组成,最厚钢板尺寸120毫米,最大截面面积180平方米,截面尺寸创世界之最。巨型柱从地下室一直贯穿至583.65米的高度,犹如擎天巨柱挺起整栋大楼。
  万一赶上地震怎么办?
  即使1根巨型柱坍塌 大厦也不会倾覆
  大厦安装的防屈曲支撑在第一道巨型斜撑下方,共设8根,单根长度约为48米、重量约为210吨,可为大厦整体结构提供很大的抗侧刚度和承载力,当大风和地震出现,大厦受到巨大冲击时,防屈曲支撑不会弯曲变形,只会出现短距离位移,从而保护主体结构、减小相邻构件受力,使大厦抗震性能成倍增加。
  大厦共设有9道环形带状桁架,包括3道双层桁架,6道单层桁架,其中第3道桁架层总用钢量达到2106吨,箱型梁及组合节点共计108件,为全国最大双层桁架。9道桁架酷似9条“腰带”,将大厦紧紧环抱。
  根据中国建筑科研院的振动台试验结果显示,在烈度为8度地震下,结构最大层间位移角达到约1/76,但结构仍保持了较好的整体性,关键构件基本完好,说明结构具有良好的变形能力和延性,具有一定的抗震储备能力。大厦如遇与“美国9·11恐怖袭击案”同等的飞机冲撞力,即使有1根巨型柱坍塌也可确保大厦不会倾覆。

  “秘密中的秘密”——
  创新:
  大厦“拔高”动力
  侯玉杰是中建三局天津117大厦项目执行总经理,“117项目侯玉杰创新工作室”正是大厦“拔高”的创新原动力,是117大厦工程建造的“智囊团”。走进创新工作室,管理组的技术人员正在针对117大厦的通道塔运输效率的监测数据进行分析与计算。在创新工作室展示区,记者看到,墙上挂满了117大厦科技创新工作总结和计划,展桌上摆放着数十份发表在核心期刊的工程论文、项目团队编写的创新管理手册,展柜里摆放着10余个科技创新的展品模型。
侯玉杰介绍说,每个模型对应的都是创新成果,也是工作室团队独立摸索、自主研发的新技术。他指着模型对记者说,117大厦使用的是中建三局自主研发的“模块化低位顶升钢平台模架体系”综合施工技术,创新工作室对顶模进行了优化设计,将顶模平面分成13个区,细化单层施工工期内流水施工的每一个工序编排,协调作业,达到各专业、各工序、各工种最大限度的满负荷工作效率。
顶模这个普通的铁罩子成为了“变形金刚”,辗转腾挪见证着工作室这个智囊团的创新能力。工作室攻克了大量建造技术难关,获得了国家实用新型专利6项、国家发明专利9项、省部级科技进步奖2项。侯玉杰表示,创新是在日常工作中不断探索、改进、提升,点点滴滴积累起来的,在劳动中创新,在创新中实现梦想,117大厦才能够从地下数十米一直建设至如今的550多米,创新一直在路上。
  万一着火怎么办?
  防火设计有妙招 10个避难层保生命安全
  超高层建筑消防工作是一个世界性难题,主要是人员疏散的困难。超高建筑虽有疏散楼梯,但靠人跑下来不现实,近600米的楼比北京香山香炉峰的高度还要高近50米,体力好的年轻人从顶部跑下来也要1个多小时。
为此,除了每层常规的消防设施外,在设计上,117大厦还设有10个避难层,最大一个避难层面积约为3625平方米;避难层分别设在6层、18层、32层、32夹层、47层、63层、63夹层、78层、93层和105层,分布在9道桁架内,结构体系与材料均为特殊设计,在大楼立面上形成10道“防火墙”,即大约每隔15层左右就有1个避难层,火灾发生后最快可以在1分钟内就近疏散到避难层。
此外,大厦所有钢结构表面都涂刷了3到5厘米厚的防火材料,能承受3小时高温火烧。大厦设有防火卷帘门2.2万余平方米,钢制防火门2.1万余平方米、木质防火门4700余平方米,疏散走道、楼梯间和前室的防火门具有自行关闭功能,待人员撤离完毕后,大门自动关闭,双扇平开防火门安装闭门器和顺位器,火警时电源自动切断,关闭信号反馈给消防控制中心。

Cars on quiet roads Tianjin Binhai New Area, from afar you can see 117 buildings tall slender figure. "Dangerous hundred feet high, the hand can pick the stars. Dare not loud language, fear shaking Master." It was originally a magnificent ancient poet's imagination, today's builders are these beautiful poems into reality. Jin Jing in the North-South Highway and Haitai street at the intersection, the building became the seat 117 8th World, Block 5, China, north China's first skyscraper over 500 meters. Recently, the reporter visited the "China construction tallest building", recorded growth of its secrets.

117 Building: China's tallest structure

May 31, the top of the North China rises again! 117 Main Tower Building, 113 Central built in the third layer of concrete pouring construction of the successful completion of the core tube structure currently marked as 553.095 meters, 117 buildings to break through 550 meters, the height has already gone beyond the total height of 541 meters the tallest building in the United States - the World Trade Center Building A, also beyond the 420.5 meters in Shanghai Jinmao Tower, 440 meters of Guangzhou West Tower, 441.8 meters of Beijing-based 100,451.9 meter Petronas Twin Towers, 492 meters of the Shanghai World Financial Center, 509 meters of the Taipei 101 building, 539 meters of Guangzhou East Tower and other famous buildings.

Boarded more than 500 meters of jacking formwork steel platform, Castle skyline glance, Tianjin TV Tower are trampled underfoot, an aircraft passing overhead. According to Executive General Manager Project Department Building 117 Hou Yujie introduction, 117 buildings will be the main tower structure needed to achieve this year, when the eaves height of 597 meters will become China's tallest structure.

Dream clouds, dreams Tianjin. In the near future, Tianjin 117 buildings at the core of the central business district Goldin Finance will become a new business district in Tianjin, but will become a new landmark in Beijing and Tianjin, and Tianjin, China's beautiful "business card."

Such a high floor, man, machine, material how to enter the construction site?

Channel tower elevator: more than 500 meters high transport aorta

Reporters sit channel tower elevator, approximately 10 minutes after the arrival of more than 500 meters altitude. On the way, along with the gradual rise in the elevator to the roof, Tianjin panoramic scenery. It is understood that the general speed of construction elevator speed of 50 meters per minute, and channel tower elevator speeds up to 90 m. Open the safe door, a channel width of 5 meters lap in each floor main tower surface. If the tower is the transport channel aorta, then the connection is capillary passage, people, machines, materials and ultimately by here to enter the building.

Vertical transportation is a big problem of super-tall skyscraper construction. Tianjin Building, 117 Main Tower needs 191,000 cubic meters of concrete, steel 40,000 tons, 143,000 tons of steel members, the peak of construction workers up to more than 2,500 people, vertical transportation enormous pressure, a lot of building materials, construction waste and workers rely on " Huashan Road "- construction elevator.

To this end, the project developed the first channel in mainland China tower technology, take "prefabrication, site assembly, overall lifting" assembly-line, high assembling efficiency, the latter is also very convenient removal. The channel column plane size is 5 m × 9 meters, the side connected to the main building, the other three sides attached to five pairs of cage construction elevator, unified command and control, to achieve "the separation of people and goods, layered stops, time up and down" greatly improved transport efficiency.

Such a large project, "jump height" how so fast?

Jacking formwork: "strait-jacket" Let Tianchang Building, 6th floor

At the top of the building, about 20 meters high a "strait-jacket" wrapped around the top of the core barrel buildings, like a "castle in the air" runs through the clouds. 117 buildings not as erection of scaffolding as general building, "long high" in secret "strait-jacket" here.

Construction of three 117 project chief engineer room Hua explained that the "strait-jacket" is the largest area of ​​the core tube jacking formwork systems - "modular steel platform Low jacking formwork system" by the steel platform, rack systems, hydraulic support system, a template system, protection systems, safety monitoring system.

Top mold the "big box", 35 meters long, 32 meters wide, maximum height of 21 meters and weighs about 1,100 tons, a 4-story, three-dimensional three-layer construction may be the core barrel, while achieving streamlined, seamless. The system will be the roof of the main tower with 117 buildings pushed to 597 m altitude, a "north China's first top."

Steel platform maximum load 1 ton per square meter can be placed on machinery and equipment, building materials, become a huge "air yard." Also includes a hydraulic system control room, equipment room, lounge and bathroom on the platform, for construction workers use rest. Rack system workers work platform, galvanized steel mesh completely closed, to prevent the risk of falls from a height. 4 large stroke hydraulic jacking formwork entire engine, by four steel columns braced entire formwork system, the column of up to 19 meters, expanding the number of stories in the three-dimensional construction, break fast super high-rise core tube structure construction problems . To ensure the formwork system more secure operation, the construction of three major lever for mold stress monitoring, which can effectively control the mold of "physical condition" to ensure safe use mold.

March 24, 2013, 117 projects first top mold system jacking success. By the Fang Shengfeng "led" the five top die group, one resident control room, and the remaining 4 per person in charge of a hydraulic jack, complement each other. If you encounter strong wind, crane elevator outage. Top mold group has several times due to high winds trapped in the top mold platform, a storm is two or three hours can not be down to dinner, had lunch by crane to hoist to the platform, hot meals hanging up after a cold. "While working hard point, but the thought of so many people in the project, only five of us who can control the largest top-mode system, they felt a sense of pride." 方圣锋 he told reporters.

117 Building Why use?
CBD Core architecture: Includes office buildings and six-star hotel
Tianjin 117 buildings, underground 4 floors, 117 on the ground floor, 597 meters high, with a total construction area of ​​847,000 square meters, the highest skyscraper in the world of the construction area, the Department of 一幢 set grade office, hotel, tourism and business in one of the boutique The large super-tall skyscrapers. Building, first floor 65 m × 65 meters, the building area of ​​4,200 square meters, up 0.88 degree angle drill narrow, the top 46 m × 46 meters, the construction area of ​​2,100 square meters.
117 Building architectural design combines the Chinese traditional culture and modern aesthetics, is the core of the building Goldin central business district, the business area also has a boutique business, finance corporate headquarters building, the Petronas Twin Towers office buildings, convention centers, serviced apartments, high-end high-rise residential and villas, with a total of up to 338 meters of the commercial gallery will connect 117 corporate headquarters building and finance together, six diamond shape rotunda become commercial gallery's entrance, the main tower building with 117 diamonds top shape echoes chic.
Deputy General Manager of Tianjin Li Chien Chun 117 building project description, building equipped with international standard Grade A office buildings and six-star hotel. Grade A office tenants and customers to target multinational and international companies. 94 layer to 104 layers of six-star hotel construction standards will introduce Burj Al Arab, the building at 115 level, has a luxurious swimming pool at 564 meters, will create a new world record as the world's tallest indoor pool.
Building 116 will be provided in the mezzanine level of the world's highest observation deck, located inside the diamond shape, height of 579 meters, it will be broken up by the Shanghai World Financial Center, created in 2009, 474 meters, "the world's highest observation deck" Guinness Book of World Records as the world's highest observation deck, where the panoramic view of the city skyline in Tianjin.
Building site complex geological structure supposed to?
"Skeleton" Bel tough: nearly roots and build a strong foundation for long pile
117 seat building complex stratum structure, is silt, silt and silty clay-based interactive marine and continental sediments, in order to pile firmly support 117 buildings, 941 is designed as a 120 m long pile building foundation, created the most housing construction field pile length. Diameter of 1 meter meter long piles through five relatively aquifers, in a complex geological environment to ensure the verticality of the pile is not more than 1/300, to ensure that no hole collapse, ensure the hole bottom sediment thickness of less than 10 cm, guarantee thickness and underwater piles of piles of concrete reinforcement cage smooth pouring concrete protective layer, which is very difficult challenge.
Construction of three integrated in Shanghai, Wuhan and other coastal areas of Riverside deep foundation pit construction experience, combined with the geological situation in Tianjin carefully prepared long pile construction technology programs. Selection ZSD2000, GPS-20 and other types of drilling rigs, the use of gas lift reverse circulation technology and ultra-deep drilling mud deep sand control technology for 120 m long pile in construction. By constantly adjusting the mud weight and into the hole drilling speed and other technical parameters, finalized a reliable long pile construction program, and the successful capture of verticality control less than 1/300 of a worldwide storm, has been tested and meet all criteria for a class of pile. 941 long pile and 65,000 cubic meters large floor build a strong foundation for the building.
Well super-tall skyscraper structure, solid?
Steel plus concrete: a giant frame to build a solid "backbone"
Design 117 buildings a "reinforced concrete core wall + mega frame" structure system, it is the most scientific form of super-tall skyscraper design. Since the high-rise building too uneconomical, too light and unstable, so more than 400 meters tall ships will not use pure steel, instead of using a combination of steel plus concrete form. Four giant columns, eight of the largest BRB, nine endless belt truss, eight giant bracing and a total of 153,000 tons of steel components together constitute the main building solid "backbone."
Giant columns distributed in the four corners of the tower, a single cross-sectional size of 45 square meters at the largest, the highest level super giant column sectional dimension of the world. Hexagonal diamond giant column was inside the 26 cavities composed of the thick steel plate size 120 mm, maximum cross-sectional area of ​​180 square meters, the cross-sectional dimensions create the world. Giant column from the basement has been through to 583.65 meters of altitude, like Atlas pillars straighten the entire building.
Catch up with how to do in case of an earthquake?
Even a giant pillar collapsed building will not capsize
Building installation BRB beneath the first giant bracing, a total of eight, a single length of about 48 meters, and weighs about 210 tons, can provide great lateral stiffness and bearing capacity of the overall structure of the building, When high winds and earthquakes occur, the building has suffered tremendously, the BRB will not bending deformation, displacement will only be a short distance, to protect the main structure, member adjacent the force decreases, so that the seismic performance of buildings multiplied.
Building, with a total of nine endless belt truss, including three double truss, six single truss, the first three of the total amount of steel truss layer reaches 2106 tons, box beam and a total of 108 composite joints for the entire country Maximum double trusses. 9 truss resembles a 9 "belt", will be closely surrounded the building.
The vibration table test results of the Chinese Academy of Building Research shows that in the intensity of 8 degree earthquake, the maximum drift angle between the structure of about 1/76, but the structure remains good overall, the key component largely intact, the structure Good deformation capacity and ductility, a certain seismic reserve capacity. Tower case with the "September 11 terrorist attacks on the US case" aircraft collision force equal, even if there is a collapse of giant columns can also ensure that the building will not fall over.

"Secret of secrets" -
Innovation:
Building "overstating" power
侯玉杰 is the Managing Director of the construction of three 117 building projects in Tianjin, "117 Project Hou Yujie Innovation Studio" is the building "overstating" the driving force behind innovation, engineering and construction of the building is 117 "think tank." Into Innovation Studio, the management group and technical personnel are analyzed and calculated data for monitoring the efficiency of the transport channel 117 tower building. In the Innovation Studio display area, the reporter saw the walls covered with 117 buildings and technological innovation work plan summary, exhibition desk with dozens of projects in the core journals published papers, the project team prepared innovation management manual, Showcase are placed in more than 10 scientific and technological innovation exhibits models.
Hou Yujie said, each model corresponding innovations are also explored independent studio team, independent research and development of new technologies. He pointed to the model told reporters that 117 buildings using composite construction techniques in the construction of three self-developed "modular steel platform Low jacking formwork system" Innovation Studio has been optimized for the top mold design, mold top plane is divided into 13 zones, each refinement step choreography water monolayer construction workers during construction, coordination of operations, to the professional, the process, the types of work at full capacity to maximize efficiency.
Top mold this ordinary iron cover has become a "Transformers" walk a fine line to witness the creative ability of the studio to the think tank. Studio capture a large number of construction technical difficulties, we won six national utility model patents, the national patent 9, the provincial Science and Technology Progress Award 2. Hou Yujie said that innovation is constantly exploring in their daily work, improve, enhance, bit by bit accumulated, innovation in labor and realize their dreams in innovation, 117 buildings have been able to build tens of meters from the ground to over 550 meters now Innovation has been on the road.
How to do in case of fire?
Fire Design 10 coup refuge floors ensure safety of life
High-rise building fire prevention is a worldwide problem, mainly the difficulty of evacuation. Although high-rise buildings staircases, but by people running down unrealistic, building nearly 600 meters higher than Beijing Xiangshan Hyangnobong height of nearly 50 meters, the physical good young man ran down from the top have more than one hour .
To this end, in addition to each regular fire facilities, the design, the building also has 10 117 refuge floors, maximum a refuge floor area of ​​about 3625 square meters; refuge floors are located on the 6th floor, 18 floors, 32 floors 32 mezzanine, 47 layers, 63 layers, 63 mezzanine, 78 layers, 93 layers and 105 layers, distributed in nine trusses, structural systems and materials are specially designed building facade in form 10 "firewall" That is about 15 layers have a refuge floor after the fire the fastest possible evacuation to the nearest refuge floors in one minute intervals.
In addition, all steel surfaces are painted building a 3-5 cm thick fireproof material that can withstand high-temperature fire three hours. The complex has fire doors 2.2 million square meters, 2.1 million square meters of steel fire doors, wooden fire door, more than 4,700 square meters, evacuation corridors, stairwells and fire before the room door closed with its own function, until the evacuation has been completed door closes automatically double Shanping open fire door closers cis-bit device is installed, power is automatically cut off when a fire, turn off the signal back to the fire control center.
