MQH-84型玻璃温室具有一些良好的特性。该温室由于采用了“大”字形中间架、连续梁檩条”,单位面积用钢量少,仅为9kg/m~2。和“人字形中间架、简支梁檩条相比,檩条每米省钢19％,变形减小18％;中间架省钢50—60％,刚度增加8—14％。只就用钢量最多的温室屋架和檩条两项而言,比沪—81型玻璃温室节省钢材40％;温室的其它性能也有明显改进。本文主要对这一新型温室的结构特性进行分析。 MQH-84 glass greenhouse has some good features. The greenhouse as a result of the use of “large” shape of the middle of the frame, continuous beams purlins, “small amount of steel per unit area, only 9kg / m ~ 2. And” chevron frame, simply supported purlins, purlins per meter province Steel 19%, 18% reduction in deformation; intermediate frame steel province 50-60%, stiffness increased by 8-14%. Only with the largest amount of steel greenhouse truss and purlin two terms, than the Shanghai -81-type glass greenhouse saves 40% of the steel; other properties of the greenhouse has also been significantly improved. This paper mainly analyzes the structural characteristics of this new greenhouse.
