Burj Dubai 大楼拾趣
最后还提到了该大楼的窗户清洗和幕墙维修系统
Interesting facts on Burj Dubai
•The tip of the spire can be seen by a person 95 km (60 miles) away.
•The amount of rebar used for the tower is 31,400 tonnes – laid end to end this would extend over a quarter of the way around the world.
•The tower’s peak electricity demand is estimated at 36 kVA, equivalent to roughly 360,000 100-watt light bulbs all operating at the same time
•The concrete to be used for the Burj Dubai is equivalent to: a solid cube of concrete 61 m (200 ft) side or over five times the volume of concrete used for the CN Tower in Canada.
•Its water system will supply an average of about 946,000 litres (250,000 gallons) of water per day.
•At the peak cooling times, the tower will require approximately 10,000 tons of cooling per hour, which is equivalent to the capacity provided by 10,000 tonnes (22.4 million lbs or 10.2 million kg) of melting ice in one day.
•The building service/fireman’s elevator will have a capacity of 5,500 kg and will be the world’s tallest service elevator.
•It will be the first mega-high rise in which certain elevators will be programmed to permit controlled evacuation for certain fire or security events.
•There will be 200 m of spectacular dancing fountains at the foot of the Burj Dubai.
•The observatory elevators (double deck cabs) have a capacity for 21 persons on each deck.
•The observation deck is located 442 m above ground will be the highest publicly accessible observation deck in the world.
•Condensate collection system collecting condensed water in the building will provide about 15 million gallons of supplemental water per year, equivalent to nearly 20 Olympic-sized swimming pools.
•The tower’s primary window washing and facade maintenance system consists of three permanently-installed, track-mounted, telescopic building maintenance machines located in internal “garage” positions on uppermost levels. The manned cleaning cradle for each machine is capable of serving the entire facade from its garage level downward to level 7. Each machine’s jib arm, when fully extended, will have a reach of over 36 m with an overall length of about 45 m. When collapsed into its parking position, the arms will measure about 15 m.
