Abstract

本实用新型涉及了一种新型菱镁大棚杆。主要解决现有大棚杆安装使用不便、造价高、强度低的问题。其特征是菱镁水泥、填料、改性剂组成的混合泥浆,与木质纤维玻璃丝布层层卷叠式或混合泥浆与长木质纤维互混结构,整体呈抛物线状,外部两侧面呈梯型,内外侧面呈长方形。本实用新型重量轻、造价低、承载强度较传统棚杆提高3倍。易于国内农村大面积推广。

Description

新型菱镁大棚杆
本实用新型涉及了一种农业生产上使用的大棚构件。
目前社会上的菱镁大棚杆,主要是用来建造无支柱大棚。棚杆分两种,一种是笨重型,另一种是轻便型。笨重型棚杆其结构形状为四菱柱形,其截面为长方形,截面的长与宽多为15cm-10cm之间,且整体形状一致,骨筋为竹条。轻便型棚杆,其结构形状为园柱形,截面直径在5-6cm之间,整体一致,用玻璃丝布作骨筋。但笨重型菱镁大棚杆建棚时杆与杆之间的距离要比较大,一般在300cm以上,两杆之间仍要横向担多根竹杆,造价较高。如果使两杆之间距离缩小,要多用棚杆,造价更高,且按装不便。轻便型棚杆,杆与杆之间的距离为150-200cm,由于较细,强度较小,在按装时,稍有疏忽便容易断杆,塌棚。
本实用新型的目的是提供一种新型的棚杆,克服目前菱镁大棚杆造价高、强度低,且按装不便的问题。
本实用新型为菱镁水泥、填料、改性剂组成的混合泥浆,与木质纤维玻璃丝布层层卷叠式或混合泥浆与长木质纤维互混结构,整体呈抛物线状,外部两侧面呈梯型,内外侧面呈长方形。
本实用新型具有以下优点:
①该棚杆体积较小,又用轻质材料作填充剂,因而比重小,整体轻。
②因换用廉价材料作填充料和骨筋,所以较其他同类棚杆造价低。
③因截面形状为长方形,整体形状根据受力大小而由大变小,结构合理,且受力方向上的宽度较大,承载能力要比截面积相同的园柱型棚杆提高3倍。
图一为本实用新型正视图,图二为本实用新型横截面图。
下面结合附图详细介绍本实用新型实施例:
如图二所示,本实用新型是菱镁水泥、炉渣、改性剂组成的混合泥浆(1)与挤压过的树枝条(或棉秸)(2)互混结构,如图一、二,其外部两侧面(3)、(4)为梯形,内外面(5)、(6)为长方形。整体抛物线状。
