Abstract
本实用新型公开了一种塑料大棚的棚杆。包括管壁和管芯,管壁的横截面为圆环形,管芯的横截面为Y字形。其管壁与管芯是相互连为一个整体的注塑件。产品具有刚柔结合,撑而不弯,弯而不断,成本低,重量轻,耐腐蚀的性能。
Description
本实用新型涉及塑料大棚的构件，特别是涉及一种农用塑料大棚的支撑塑料薄膜的棚杆。
塑料大棚在农业生产中得到日益广泛的应用，塑料大棚的塑料薄膜需要用棚杆进行支撑，现有的塑料大棚一般是采用金属或者竹子作棚杆。但是，金属棚杆吸冷吸热快，金属棚杆的温度变化大，容易加速与棚杆接触部位塑料薄膜的老化与破裂；加之，金属棚杆表面不够光滑，摩擦系数大也使塑料薄膜容易损坏。而用竹子作棚杆，由于棚杆的两端是埋在潮湿的土壤中，过一段时间棚杆就腐朽变坏，直接影响大棚的使用寿命；同时，由于需要砍伐大量竹木，不利于生态环境的保护。而现有的塑料管材，例如：建筑用的穿线管，其支撑力较弱，在弯曲情况下，很容易发生断裂。这是塑料大棚建造中长期存在的一个技术难题。
本实用新型的目的是针对现有技术的不足，提供一种适合塑料大棚使用的棚杆。
本实用新型的目的是这样实现的：塑料大棚的棚杆包括管壁和管芯，管壁的横截面为园环形，管芯的横截面为Y字形。
所述的管壁和管芯是相互连为一个整体的注塑件。
与现有技术相比，本实用新型具有以下突出优点：1、产品既有支撑力强，又有弯曲不断的特点，刚柔结合，撑而不弯，弯而不断，是一种十分理想的塑料大棚的棚杆；2、棚杆表面光滑，摩擦系数小，不磨损塑料薄膜，同时由于棚杆温度变化小，棚杆与塑料薄膜的接触部分不易老化。3、重量轻，成本低，耐腐蚀，可有效地降低塑料大棚的造价，具有显著地经济效益，同时又可减少竹木消耗量，有利于环境保护。
下面结合附图详细说明依据本实用新型提出的具产品的细节及工作情况，但本实用新型的内容不限于附图所示。
图1是根据本实用新型提出的塑料大棚的棚杆横截面的示意图；
图2是图1中的A-A部视图；
图3是图1所示棚杆的俯视图。
如图1所示，塑料大棚的棚杆包括管壁1和管芯2，管壁1的横截面为园环形，管芯2的横截面为Y字形，管壁1与管芯2为相互连为一个整体的注塑件，即整个棚杆为一次注塑成型。
Claims (2)
1、一种塑料大棚的棚杆，其特征在于包括管壁和管芯，管壁的横截面为园环形，管芯的横截面为Y字形。
2、按照权利要求1所述的棚杆，其特征在于所述的管壁与管芯是相互连为一个整体的注塑件。
