How long is the ceiling overhang for high-rise buildings?
In addition, even if the calculation of anti overturning moment can meet the standard requirements of the extended forearm, also need to consider the extension cantilever stiffness is enough, generally more than 2 meters above the length of them requires the use of two reinforcing steel wire rope improve stiffness.
In the formal business of the standard basket case, limit state, before the beam maximum extended length of 1.9 meters, in the extended length, only by reducing the rated load and increase the additional weight to meet the anti overturning moment is greater than 2 of the requirements.
In fact, the country does not specify the length of the front arm of the basket, but does it mean that the front arm can be stretched out? The answer is no.. Referring to the national standard 5.2.7 of GB19155-2003 height hanging basket, the ratio of overturning moment and overturning moment of the suspension mechanism in the normal working condition shall not be less than 2.
