上海环球金融中心主要成绩

液压自动爬模体系 混凝土一次泵送至492米高空 90层设水箱阻尼抵抗风震 整体卫生间

创摩天大厦施工“之最” 上海建工再上新台阶 2007年09月18日 来源：上海证券报 作者：⊙本报记者 杨伟中

日前结构封顶的上海环球金融中心拥有建筑屋顶高度世界第一与人可到达高度世界第一。掀开这两个“世界第一”神秘面纱，不难发现此项工程的总承包 商，即以上海建工为主体的上海建工集团与其合作伙伴中国建筑总公司，在建筑科技探索和提高方面又攀上了一个新的台阶。业内专家认为，建设这样一座摩天楼堪 称是一次国家乃至世界级的建筑科技水平的大检阅。 　　上海环球金融中心主体结构为型钢混凝土组合结构和钢结构，由核心筒结构、巨型柱、巨型 斜撑、带状桁架、伸臂桁架、转换层桁架、劲性桁架和90层以上的压顶桁架组成主要的受力结构，抗震等级达到特一级，为世界超高层建筑结构所罕见。上海环球 金融中心工程从打桩到封顶，中国建筑总公司和上海建工集团的建设者们攻克了无数的施工难题，创出了一项项令人叹为观止的行业“施工之最”。 　　其一，超高层建筑施工采用自行开发研制的整体提升钢平台模板体系和进口的液压自动爬模体系，在上海环球金融中心塔楼核心筒和巨型柱结构施工中发 挥了独特作用。运用这些先进的工艺和技术，创出了塔楼核心筒和巨型柱施工的世界先进水平。 　　其二，高强度、高耐久、高流态、高泵送混凝土技术在上海环球金融中心施工中见奇效，刷新了一次连续40个小时浇筑主楼底板3万余立方混凝土的国 内房建领域新纪录和混凝土一次泵送至492米高空的世界纪录。 　　其三，上海环球金融中心吊装中采用的2台M900D塔吊，是目前国内房建领域中起重量最大、高度可达500米的巨型变臂塔吊，塔吊总重量达 225.40吨。大厦封顶后，该塔吊将在500米高空拆卸，这也是世界范围内尚无先例。 　 　其四，为提高遭遇强风时大厦酒店和办公人员使用环境的舒适性，上海环球金融中心在90层安装了2台用来抑制建筑物由于强风引起摇晃的风阻尼器，这是中国 大陆地区首座使用风阻尼器装置的超高层建筑。该装置通过使用传感器，能够探测强风时建筑物的摇晃程度，抑制建筑物的摇晃。 　　据了解，上海 环球金融中心已经创出和正在创出的施工“之最”还包括：国内首次运用工程质量远程验收系统应用在钢结构工程质量验收上，在办公室轻点鼠标，小至钢结构焊缝 都能清晰可见；国内首次采用预制组合立管技术，均在外加工成型后分段整体吊装，在楼板钢结构安装完成后安装预制组合立管，随结构同步攀升；国内首次在 450米的垂直竖井内进行电缆敷设；采用国内少见的工厂拼装、现场预留管口对接的整体卫生间施工工艺，使安装和拆卸非常方便；在85层建“世界最高的游泳 池”，在78至93层建“世界最高档次的酒店”，并在93层设置“世界最高的中餐厅”；在94层建室内净高8米、700平方米的观光大厅和在100层、距 地面472米处建观光天阁，将成为以上海都市全景为背景的世界新的观光景点；采用10米/秒的世界上最快的双轿厢电梯等等，使这座大厦的抗地震和抗强台风 的能力达到了当今世界领先水平。

Bob Young对lulu.com的愿景

Bonjour and hello from Bob Young, CEO and founder of Lulu.com
Lulu is not only revolulutionary, but we are undergoing a revolulution ourselves. In the coming weeks I’ll be posting some exciting news about our dramatic new release, we’re calling “Lulu 2.0”. But I thought I should start by explaining what is remaining the same at Lulu because of the founding principles of our business.
Lulu is founded on a couple of simple concepts. The first is the Internet’s unique feature - it connects everyone to everyone else. The other is that creators need to be paid for the work they create if they are going to create more and better works.
Lulu was created to empower a new generation of content producers, authors, photographers, musicians, and educators. Our goal is to help you bring your work to your audience whether it is a photo book for your family reunion, or a series of sophisticated professional training videos and manuals for you company’s new products. Taking advantage of the Internet’s unique feature, we figured we could build a set of tools that would enable you to better serve the audience for your work, whether that audience is your extended family, your school, your company, or your customers.
The other founding concept behind Lulu’s success is to help you get paid for your work. So whether you just need to be compensated for the cost of printing and shipping your family history to family members around the world. Or your goal might be to make a living writing novels or poetry. Or you might be trying to build a business teaching technology to your global customers. In all these cases and many many more, Lulu is building tools to enable you to successfully serve your customers. So features of Lulu, such as our commitment to leave you with full control and ownership of all your rights in the content you have created are not a benevolent act on our part. It is simply a necessary part of our goal, namely to empower creators to create millions of unique and valuable pieces of content for your audiences. This simple goal also explains why we work so hard and take so many chances to improve Lulu.
Our business model is almost the exact reverse of the existing publishing industries. Which is a big part of why they don’t have to worry too much about us. Where they would love nothing better than to get their stable of authors, or musicians, ie creators, down to say just 10. And then have those 10 creators produce a new work every year and sell a million copies, resulting in sales of ten million copies.
Lulu is looking to create the reverse – we want to create a million, or ten million, or a hundred million authors. Whether you publish and sell a few copies, or a few thousand copies or more, it still adds up to a lot of copies of your works.
To be precise Lulu now hosts over a million and a half registered users. Over 300,000 authors have created over a half million works that are available on Lulu already. All these numbers are growing at over 10% per month! This scale of success will enable us to continue to expand the scale and quality of the services we can offer to you, your readers, your audience, and your customers.
Our site had better continue improving if we are both going to keep making you happier and happier with our service. And to look after the millions of new creators you keep recommending to Lulu.
Next week I’ll discuss some of the cool new tools our engineers and designers have unveiled with the recent launch of Lulu 2.0.
Until then, let me know what you think about Lulu 2.0 so far by sending me your comments to askbob@lulu.com
Cheers, Bob. 来源
