Abstract

The invention discloses a large-span circular dome and an installation method of same. The installation method is characterized in that: a circular steel rack with the span being more than 100m is arranged on a steel upright post or wall body, a purlin layer and a sun panel layer are sequentially arranged outside the steel rack, the purlin layer comprises a transverse purlin structure and a longitudinal purlin structure, a packway is arranged outside the steel rack, the sun panel layer is provided with an un-powered blower, and the sun panel layer is arranged in a direction of the vertex ray of the steel rack. Since the circular steel rack with the span of more than 100m is arranged on the steel upright post or the wall body, the purlin layer and the sun panel layerwhich is arranged in the vertex ray area of the steel rack are sequentially arranged outside the steel rack, the packway is arranged outside the steel rack, and the un-powered blower is arranged on the sun panel layer, the large-span circular dome has the characteristics of simple structure, convenience in realization and good waterproof effect. The large-span circular dome also has the characteristics of large span and suitability in large fields.
本发明公开了一种大跨度圆形屋顶以及该屋顶的安装方法,其特征在于:包括在钢构立柱或墙体上设置的跨度在100米以上的圆形钢构网架,在钢构网架的外部依次设置檩条层和阳光板层,所述的檩条层包括由横向檩条结构和纵向檩条结构,所述的钢构网架的外部设置马道,所述的阳光板层上设置无动力风机,所述的阳光板层是以钢构网架的顶点射线向区域设置。由于采用在钢构立柱或墙体上设置的跨度在100米以上的圆形钢构网架,在钢构网架的外部依次设置檩条层和以钢构网架的顶点射线向区域设置的阳光板层,钢构网架的外部设置马道,阳光板层上设置无动力风机。具有结构简单,实现方便,防水效果优良的特点。并且还具有跨度大,适用大型场所的特点。
