Description

双拱双跨圆弧形大拱棚
技术领域
本实用新型涉及一种拱棚，具体地说是双拱双跨圆弧形大拱棚。
背景技术
传统的大拱棚结构，由于保温能力较差，冬季棚内夜间温度较低，一般仅用于进行蔬菜春早熟和秋延迟栽培，冬季无法利用，设施的周年利用率较低。提高大拱棚的采光增温能力和保温效果，改善大拱棚的光、温性能，从而提高大拱棚的周年利用率，是人们迫切需要解决的问题。要想提高和改善大拱棚的光、温性能，关键是优化大拱棚结构，设计和建造最佳的棚面角度和形状，提高大拱棚的采光性能，增加大拱棚的保温和蓄热能力，提高大拱棚的夜间保温效果，已成为人们的普遍要求。
发明内容
本实用新型的技术任务是针对以上不足之处，提供一种采光性能更好，蓄热量更大，保温能力更强的双拱双跨圆弧形大拱棚。
本实用新型解决其技术问题所采用的技术方案是：棚体截面为两个圆弧形拱架相连接构成的双跨，连接点固定在立柱上，棚体设置有内外两层圆弧形拱架，外圆弧形拱架上设置有透光膜，内圆弧形拱架上设置有保温幕，外圆弧形拱架和内圆弧形拱架上均固定有纵拉杆。
棚体的高度为该外圆弧形拱架所在圆的半径。
本实用新型的双拱双跨圆弧形大拱棚和现有技术相比，具有以下特点：
一是采光效果最佳，圆弧形受光面采光效果最佳。二是保温性能良好，球体的内容积最大，在加上多层覆盖保护，保温性能较传统大拱棚相比，有较大改善。三是结构更加合理，大拱棚骨架的承载力和抗风雪能力更强。
附图说明
下面结合附图对本实用新型进一步说明。
附图1为双拱双跨圆弧形大拱棚的结构示意图；
附图2为图1纵向结构示意图。
具体实施方式
参照说明书附图对本实用新型的双拱双跨圆弧形大拱棚作以下详细地说明。
本实用新型的双拱双跨圆弧形大拱棚，棚体截面为两个圆弧形拱架相连接构成的双跨，连接点固定在立柱6上，棚体设置有内、外两层圆弧形拱架，外圆弧形拱架2上设置有透光膜1，内圆弧形拱架5上设置有保温幕4，外圆弧形拱架2和内圆弧形拱架5上均固定有五根纵拉杆3。
本实用新型的双拱双跨圆弧形大拱棚其加工制作非常简单方便，按说明书附图所示加工制作即可。
除说明书所述的技术特征外，均为本专业技术人员的已知技术。
