Free-form surface reticulated shell structure formed by dual-limb sheet bar composite members
The invention discloses a free-form surface reticulated shell structure formed by dual-limb sheet bar composite members. The reticulated shell structure uses dual-limb sheet bars as the main stress members; and through optimization after structural configuration, different members at one joint intersect on the same joint axis, the joint axis is in the surface normal direction, a mold of a free-form surface is formed by arc-shaped outlines of the corresponding members in a fitting manner, and the assembly type single-layer reticulated shell structure is formed. Each dual-limb sheet bar composite member is formed by two arc-shaped metal branch-limb sheets and a plurality of base plates, and the arc-shaped metal branch-limb sheets and the base plates are overlapped and then are connected through bolts in a penetration manner. According to the free-form surface reticulated shell structure formed by dual-limb sheet bar composite members, the lateral bending resistance rigidity is effectively improved while the advantages of one single sheet bar about machining, transportation and construction are kept; and with the reticulated shell structure, a curved-surface mold with high degree of freedom can be implemented, the appearance is attractive, the structure is reasonable, the strength is high so that stability is achieved, and the applicability is high.
本发明公开了一种由双肢板片组合构件构成的自由曲面网壳结构，该网壳结构以双肢板片为主要受力构件，经过结构构型后优化使节点处不同构件相交于同一节点轴线，且节点轴线方向为曲面法线方向，从而以构件的弧线形轮廓拟合自由曲面的造型，形成装配式单层网壳结构。其中，双肢板片组合构件通过两块弧形金属分肢板与若干垫板叠合后通过螺栓贯通连接构成，在保留单块板片加工、运输、施工优点的同时，有效提高了平面外抗弯刚度。这一结构可以实现高度自由的曲面造型，外形美观，结构合理，强度可靠，适用性强。
