21世纪工业厂房屋顶展望

PROSPECTS FOR THE FACTORY ROOF IN THE 21ST CENTURY

我国工业厂房屋顶形式一直采用多跨天沟水落管排水 ,这种形式已被充分证明存在许多缺点 ,如 :排水不畅 ,构造和施工复杂 ,维修困难 ,造价高 ,此外还损失大量太阳能 (由于反射作用 )和屋面雨水。为克服上述缺点 ,通过调研与试验 ,建议对于现有多跨天沟水落管排水屋顶 ,采用天沟种植是简易可行的办法 ;对于待建多跨屋顶 ,采用天沟缓坡屋顶并使屋面可进行种植与多功能转换太阳能 。

In China,the factory roofs are still taking the shape of multi-span gutter piped drainage,it has been full proof that exists many shrotcomings such as bad drainage,complex construction and built-up,difficult maintenance and high cost,besides,much reflective solar energy and roofing water lost.To overcome above shortcomings,through investigation and experiments we get such suggestion.For existing multi-span gutter piped drainage roofs,using gutter planting is the way of easy doing.For the multi-span roofs of going to be built,using a gentle slope roofing without any gutter and making the roofing not only with planting but also multi-conversion of solar energy that may be one of the best sustainable developing ways.
