Hybrid string grid structure and use method thereof
The invention provides a hybrid string grid structure, and relates to the field of string beam structures, the hybrid string grid structure comprises a tensioning two-rod structure unit with two rod pieces, and the tensioning two-rod structure unit is configured to form a three-jaw orthogonal rod assembly during deformation; the two groups of three-jaw orthogonal rod assemblies are oppositely arranged at a certain rotation angle and are connected through the connecting rods, and the boundaries of the two groups of three-jaw orthogonal rod assemblies are enclosed through the tension cables to form a hybrid string grid structure. The hybrid string grid structure is a self-balancing structure unit, can adapt to positive and negative bidirectional load effects, keeps structural stability, and improves the defects that under the negative load effects of wind pressure suction and the like, an existing string beam roof structure is prone to instability due to the fact that inhaul cables change prestress forms, and stable pull rods need to be added to tie and fix the inhaul cables; and the pre-stress form can be maintained.
本发明提供一种杂交张弦网格结构，涉及张弦梁结构领域，包括具有两个杆件的张拉两杆结构单元，所述张拉两杆结构单元配置为在进行变形时会形成三爪正交杆组件；两组所述三爪正交杆组件相对、呈一定旋转角度设置，并通过连接杆连接，且两组三爪正交杆组件边界通过张拉索围合，以形成杂交张弦网格结构。该杂交张弦网格结构为自平衡结构单元，能够适应正负双向荷载作用，并保持结构稳定性，改善现有张弦梁屋面结构在风压吸力等负向荷载作用下，由于拉索改变预应力形态，容易失稳，需增加稳定拉杆拉结固定拉索，才能保持预应力形态的问题。
