新型竹—PVA纤维混凝土大棚棚架结构研究

Study of new bamboo-PVA fiber reinforced concrete greenhouse trellis structure

为了优化大棚棚架结构,节省投资,设计出一种新型的竹—PVA纤维混凝土组合结构拱架。将两组PVA纤维混凝土边桁架和一个由环氧树脂粘结而成的T型截面竹拱梁通过一定方式连接形成一榀竹—PVA纤维混凝土大棚棚架。两边为由钢筋骨架、PVA纤维混凝土组成的混凝土边桁架,中间为由竹胶板粘结而成的T型截面竹拱梁。该结构兼具竹结构经济性和混凝土结构强度高、耐久性好的优点。

In order to optimize the greenhouse trellis structure,saving investment,a new type of bamboo-PVA fiber reinforced concrete composite structure arch is designed. Two groups of PVA fiber concrete side truss and an epoxy resin bonded to the T section of bamboo arch through a certain way connected to form a bamboo-PVA fiber concrete shed by reinforced on both sides of scaffolding. The skeleton,composed of PVA fiber concrete concrete side truss,T section arch bamboo bamboo plywood bonded by the middle of the bamboo structure. The structure of both economy and concrete structure of high strength,good durability.
