目前在我国很多大型厂房建筑中,自然采光,通风效果和外观很差,特别是电厂机炉主厂房。主要原因是式样单调,结构陈旧,以下两点较为突出。 1.采光仍然是小块组合型的普遍结构型式。高度大、面积大这是大型厂房采光的特点,带来的问题是清洗,维护极不方便,很多厂房的采光窗破烂不堪,积灰一层,不但外观差而且也严重降低采光度。 At present, in many large-scale factory buildings in China, natural lighting, ventilation effect and appearance are poor, especially the main plant of the power plant. The main reason is that the style is monotonous and the structure is obsolete. The following two points are more prominent. 1. Daylighting is still a common structural pattern of small blocks. Large height and large area This is the characteristic of lighting in large factories. The problem is that cleaning is very difficult. Maintenance is inconvenient. The light windows of many factories are extremely dilapidated and gray, which not only has poor appearance but also seriously reduces the degree of daylighting.
