Description
本发明涉及一种大棚骨架技术领域，尤其是农用大棚骨架技术领域。
农业生产进步，大棚走进普通农户家，农用大棚来生产时新蔬菜和花卉，人们常用空心钢管作为大棚骨架，如专利号为95232346.X的中国专利“无立柱塑料大棚”，其骨架就为空腹型钢制成。其缺点有：不防晒，夏季阳光照耀下，钢管易吸热发烫，表面温度甚至可超过70℃，所以覆盖于其表面的塑料薄膜容易烫破熔化，造成漏水，不保温，结果损害农作物生长；强度不够，由于骨架为空心钢管制成，因此骨架抗压抗风强度有限，曾经发生过大雪天，厚雪压塌农用大棚现象，破坏农业生产；不隔氧，由于是空心钢管，其内外表面部分接触有氧气，尤其在露天，每天接触有水汽，极易生锈腐烂，影响使用寿命；自身重，由于采用空心钢管为管壁较厚钢管，自身重量也较大，不利于国家要求。
本发明的目的在于提供一种具有防晒、抗老化、强度大、又能隔氧、大大延长使用寿命的大棚骨架。
实现本发明目的的技术方案是这样的：该大棚骨架包括空心钢管，其特征在于所述空心钢管外表面包有塑料层，同时空心钢管内充填有基物。
上述塑料层表面分布有反射光线的棱条；上述基物可为低碱水泥、膨胀珍珠岩、建筑胶混制的硬质、轻质建筑材料；也可为水泥砂浆或玻璃纤维增强的水泥砂浆建筑材料；也可为菱苦土、氯化镁、填充改性剂混制的菱镁类硬质轻型建筑材料。
该大棚骨架由于表面包有塑料层，在夏季能有效阻止钢管吸热发烫，又由于表面反射光线条纹，能控制大棚骨架表面温度在50°以下，有效防止塑料薄膜被熔化烫破现象，钢管充填基物，既起到隔氧作用，防止钢管内表层被氧化腐烂，延长大棚骨架使用寿命，又能增强大棚强度，不易被大雪压塌或被狂风吹掉，同时充填基物为硬质轻型建筑材料，成本低、重量轻，能减轻大棚骨架自重，又能降低生产成本。新结构的大棚骨架还能为国家节省钢铁材料，同样规格强度情况下，生产成本低，使用寿命长，防腐蚀、防晒，适宜农业大棚推广应用。
附图说明：
图1.本发明大棚骨架截面剖视图。
下面结合附图对本发明的实施例作进一步描述。
如图所示：该大棚骨架有一空心钢管2，一般可采用圆管、方钢管及其它几何型材料，直径在15～80毫米之间，壁厚较适宜在0.3～1.8毫米，外表面包一层塑料层1，一般为0.5～3毫米，采用抗紫外线、耐老化工程塑料，塑料层表面分布有反射光线的棱条，同时空心钢管内充填有基物3，可以采用硬质轻型建筑材料，如低碱水泥、膨胀珍珠岩、建筑胶聚乙烯醇混制的硬质轻型材料，也可为菱苦土、氯化镁、填充改性剂混制的菱镁类等硬质、轻型材料，也可为水泥砂浆或玻璃纤维增强的水泥砂浆建筑材料。
