正交正放网格钢筋砼空腹夹层网状筒壳与筒拱屋盖结构
摘要：
本发明公开了一种正交正放网格钢筋砼空腹夹层网状筒壳与筒拱屋盖结构，它由钢筋砼空腹夹层板(1)呈圆曲线或抛物线形状单向弯曲而成。与现有技术相比，本发明的结构折算厚度小，比一般实心截面的网状筒壳和网状筒拱结构的折算厚度小30％～50％，结构自重下降30％～50％，具有砼用量小，制作成本低，耐久性、防锈、防火性好，维护费用低，施工工艺简单、施工进度快等特点。
摘要（英）：

The invention discloses a meshed barrel shell with hollow lamination of orthogonal mesh steel bar concrete, comprising a hollow lamination board of steel bar concrete (1) bended in circular or parabola. Compared with the prior art, the invention has a small structure conversion thickness and is less than common meshed barrel shell and meshed barrel vault with solid section in a range of 30%- 50%, and the construction weight is decreased of 30%- 50%. The invention has advantages of smaller usage of concrete, lower costs of conversion, better durability, rust-proofing and fire-proofing ability, lower maintenance cost, simple construction art, and fast progress or the like.
