Description

轻质矩型塑料大棚骨架
                      技术领域
本实用新型涉及一种农用种植、养殖塑料大棚骨架。
                      技术背景
近年来全国各地使用的塑料大硼多采用竹木结构,钢制骨架,但在大棚特定的高温高湿环境中,竹木易腐蚀,使用寿命短,又需多根顶柱,加大了大棚的建筑投资。钢制骨架成本高,又极易锈蚀,一般农户难易接受,影响了大棚的普及和发展。也有人采用水泥构件和实心菱镁材料制作,但由于体积大,太笨重,不但成本高,而且运输、安装极不方便,还经常出现变形、塌架、断裂等问题,为此使之也不能广泛推广和应用。
                      发明内容
本实用新型的目的是提供一种高强,轻质,投资少,造价低,安装使用极为方便的轻质矩型塑料大棚骨架。
这种轻质矩型塑料大棚骨架的特征是骨架(1)的形状为半弓形,横截面顶部为半圆的矩形状,骨架依据蛋壳的力学原理,采用无机菱镁材料为胶凝剂(2),以玻璃纤维布为加强筋(3),内填轻体材料(4),手工模制常温固化成型、脱膜后放置一周即可使用。
图一为本实用新型大棚骨架的示意图:
图二为本实用新型大棚骨架横截面示意图:
下面结合附图对本实用新型的具体实施方式作进一步说明:先将氯化镁溶液(卤水)与改性剂(抗潮抗卤)和菱镁粉(氯化镁)按比例混合成料浆为胶凝剂(2),在矩型模具内按涂刷一遍料浆,铺一层玻璃纤维布(3),之方法涂刷4~6遍料浆,铺3~5层玻璃纤维布,内填泡沫塑料或锯沫等轻体材料(4),常温固化成型、脱膜后,放置一周即可使用。
                 本实用新型的优点
1、高强、轻质、造价底:因为轻质矩型塑料大棚骨架是依据蛋壳的力学原理制成外壳,内填轻体材料,所以它强度高具有抗风雪功能,而且重量轻,它是同体积水泥及其实心菱镁骨架重量的三分之一或二分之一,加之用料少又采用废弃的泡沫塑料、锯沫和农作物桔杆等,为此造价较低。
2、外观光滑,减少棚模的磨损,延长其使用寿命:因为轻质矩型塑料大棚骨架是模制成型,脱膜后制品外观光滑,加之顶部又为半圆形,致使和棚膜压的紧又接触好,减少磨损,大大延长了棚模的使用寿命。
3、手工操作:无需大的设备投资,同时使用的模具也为无机菱镁材料和玻纤布制成,免去了钢、塑、橡胶,高价材料。
4、无需顶柱,运输、安装使用方便:轻质矩型塑料大棚骨架不用顶柱,可以机耕,一改过去手耕锨翻的历史,大大减轻了劳动强度,同时棚顶可加高3米以上,这就更有利于农作物的生长和光照,而且易安装,省工省力,属一次性投资多年受益的理想骨架。
                 具体实施例配方表(重量%)
上表列出各组份,按本实用新型所述方法均可根据不同填充料手工模制成型,生产出理想的轻质矩型塑料大棚骨架。

Claims (2)

1、一种轻质矩型塑料大棚骨架,其特征是骨架为半弓形,横截面顶部为半圆的矩形状。
2、根据权利要求1所述的轻质矩型塑料大棚骨架(1),其特征是该骨架以无机菱镁材料为胶凝剂(2),以玻璃纤维布(3)为加强筋,内填轻体材料(4)制成。
