Office building external wall curtain wall refers to the external walls of the building is produced in the factory, the first is the metal structure supporting metal, glass and other retaining walls. Then, office building decoration on the curtain wall planning needs to pay attention to what problems? Below, take us together to understand the curtain wall planning matters needing attention.

1、关于一般料想到的外力引起的应力是安全的;由一般料想到的外力引起的变现，不得形成功用上的妨碍;并且要考虑避免因为破损或掉落对建筑物外部的损害和要采取有用的防火结构，火灾时要安全;

1, the stress caused by the external force of the general material is safe; the occurrence of the external force caused by the general material should not be obstructed successfully; and the safety of the fire should be avoided because of the damage to the exterior of the building and the use of a useful fireproof structure.

2、避免因为部件落下而引起的风险，因为料想**外力引起的应力或变位，有必要不致使构成首要面的部件或支撑它的首要部件破损或掉落，但是假如因为雨蓬、阳台、防护网等这些部件或它的碎片不会危及建筑物的外部时，不受此限。

2. Avoid the risk caused by the falling of a component, as it is necessary to expect the stress or change caused by the maximum external force, and it is necessary not to cause the damage or drop of the first component or the first component that supports it, but if the parts or its fragments, such as Hupon, the balcony, the protective net, etc., will not jeopardize the exterior of the building, It is not subject to this limit.

3、避免因为留空量而下降功用，为了追求吸收和衰减相对变位和热膨胀收缩，采取在结构体的接合部或构成面的部件接合部留余量时有必要考虑不致由此而发作功用的下降。

3, to avoid the decrease of the function because of the blank space, in order to pursue the absorption and attenuation of relative displacement and thermal expansion contraction, it is necessary to take into account the decline in the function of the joint part of the joint or components of the structure.

4、水密性和泛水，关于一般估计的雨量，有必要考虑不能侵入建筑物的内部或积存在幕墙组件的内部，要**间隔在外面或许即便侵入内部也可排出到外部。

4, water tightness and flooding, with regard to the general estimate of rainfall, it is necessary to consider the internal or integral interior of the curtain wall components that can not be intruded into the building, and to be thoroughly spaced outside, perhaps even intruded.

5、避免结露和结露珠的排出，因为一般估计的室表里空气温差和湿度差发作的幕墙组件外表和内部的结露珠不形成结构上的妨碍，有必要考虑避免结露或把结露珠排出。

5. Avoid dew and dewdrop, because the general estimated air temperature difference and humidity difference of the curtain wall components in the exterior and interior of the curtain wall do not form a structural obstacle. It is necessary to avoid dew or dewdrop.
