本发明涉及一种张拉整体结构，尤其涉及一种拥有弧形杆且杆件之间相互连接的张拉整体结构，属于预应力索杆结构技术领域。The invention relates to a tensioned integral structure, in particular to a tensioned integral structure with arc-shaped rods and interconnected rod members, belonging to the technical field of prestressed cable-rod structures.
背景技术Background technique
张拉整体结构是一些离散的受压结构包含于一组连续的受拉构件中形成的稳定自平衡结构。张拉整体结构具有通透性好、材料利用率高、造型优美等优点，受到了学术及工程界的广泛关注。A tensegrity structure is a stable self-balancing structure formed by some discrete compression structures contained in a set of continuous tension members. The overall structure of tensegrity has the advantages of good permeability, high material utilization rate, and beautiful shape, and has received extensive attention from the academic and engineering circles.
在过去几十年中，研究人员在张拉整体结构的设计、找形和优化等方面都取得了极大的进步。但在实际建筑工程领域，却极少看见张拉整体应用的身影。其主要的一个原因是，以往的张拉整体结构往往存在结构整体刚度较低的问题。而过往的研究表明，采用连续杆件作为一个受压构件的方式可提高结构的刚度和效率。目前尚无采用弧形杆件的螺旋形张拉整体结构。该结构体系可应用于步行桥、建筑连廊、建筑装置、雕塑等领域。In the past few decades, researchers have made great progress in the design, form-finding, and optimization of tensegrified monolithic structures. However, in the field of actual construction engineering, the overall application of tension is rarely seen.

However, previous studies have shown that the stiffness and efficiency of the structure can be improved by using a continuous rod as a compression member. At present, there is no helical tension integral structure using arc-shaped rods. The structural system can be applied to pedestrian bridges, building corridors, architectural installations, sculptures and other fields.

具体实施方式Detailed ways
如图1-11所示，本发明的螺旋形张拉整体结构具体实施方式如下：As shown in Figures 1-11, the specific embodiment of the spiral tensioned overall structure of the present invention is as follows:
本发明所述的螺旋形张拉整体结构由m个单体首尾相连组成，如图4。结构非环状时，由(2m+1)n个节点、mn根弧形杆、2mn根直杆、m+1根层索和2mn根斜拉索组成，结构共有2m+1个底面层，每个底面层有n个节点，并构成一个正n边形，n为大于等于3的任意整数。结构的中轴线通过每一底面层上正n边形的中心，每个底面层均垂直于结构的中轴线。所述螺旋形张拉整体结构的节点总数量由结构单体数目m和每层底面所选的正多边形边数n所确定。The helical tensioned overall structure of the present invention is composed of m monomers connected end to end, as shown in FIG. 4 . When the structure is not annular, it consists of (2m+1)n nodes, mn arc rods, 2mn straight rods, m+1 layer cables and 2mn stay cables. The structure has a total of 2m+1 bottom layers. Each bottom layer has n nodes and forms a regular n-gon, where n is any integer greater than or equal to 3. The central axis of the structure passes through the center of the regular n-gon on each bottom surface layer, and each bottom surface layer is perpendicular to the central axis of the structure. The total number of nodes of the helical tensioned overall structure is determined by the number of structural monomers m and the number of sides n of the regular polygon selected for the bottom surface of each layer.
如图5所示，节点以底面层上的正n边形为一个单位，沿着结构中轴线等距排布。沿着结构中轴线方向，后一个正n边形均较前一个正n边形顺时针转动π/n。每个单体占有三层节点，两个单体连接处共用一层节点。As shown in Figure 5, the nodes take the regular n-gon on the bottom layer as a unit, and are equally spaced along the central axis of the structure. Along the direction of the central axis of the structure, the latter regular n-gons are rotated by π/n clockwise compared with the former regular n-gons. Each monomer occupies three layers of nodes, and the two monomers share a layer of nodes at the connection.
如图7所示，所述直杆沿结构中轴线按顺时针方向连接相邻两层之间的节点，单根杆件两端节点与各自所在正n边形中心点连线在投影面上的转角为3π/n；如图6所示，所述弧形杆沿结构中轴线按逆时针方向，依次连接位于三个相邻底面层的三个节点，三个节点与各自所在正n边形中心点的连线在垂直于结构中轴线投影面上的转角为π/n，弧形杆螺旋延伸并连接路径上所有节点。直杆首尾相连，节点采用铰接形式。在同一条螺旋线上的弧形杆，首尾相连，节点采用固结形式。弧形杆与直杆相互交织，以螺旋形网状结构形式充满整个结构，构成一个受压整体。这种特殊的杆件连接形式，在结构中心支撑出一个柱形空间。As shown in Figure 7, the straight rod connects the nodes between two adjacent layers in a clockwise direction along the central axis of the structure, and the connecting lines between the nodes at both ends of a single rod and the center points of the regular n-gons where they are located are on the projection surface As shown in Figure 6, the arc-shaped rods are connected to the three nodes located on the three adjacent bottom layers in a counterclockwise direction along the central axis of the structure in turn, and the three nodes are connected to the positive n side of each The rotation angle of the line connecting the center points of the shape on the projection plane perpendicular to the central axis of the structure is π/n, and the arc-shaped rod extends spirally and connects all nodes on the path. The straight rods are connected end to end, and the nodes are hinged. The arc-shaped rods on the same helix are connected end to end, and the nodes are in the form of consolidation. The arc-shaped rod and the straight rod are intertwined, filling the entire structure in the form of a spiral mesh structure, forming a compressed whole. This special form of rod connection supports a cylindrical space in the center of the structure.
如图8所示，从第一个底面层开始，每隔一层都用一根层索将位于同一层的n个节点串连成一个正n边形，每个单体拥有两根层索，两个相连的单体之间共用一根层索。如图9所示，斜拉索按顺时针方向，连接相邻两层相邻的两个节点。层索与斜拉索构成一个连续的受拉域，位于整个结构的最外层，将弧形杆和直杆包裹在结构内部。一个由弧形杆与直杆构成的受压整体和位于结构外层的层索与斜拉索共同组成了一个抗弯刚度良好的螺旋形张拉整体结构。As shown in Figure 8, starting from the first bottom layer, every other layer uses a layer cable to connect n nodes on the same layer into a regular n-gon, and each monomer has two layer cables. , a laminar cable is shared between two connected monomers. As shown in Figure 9, the stay cables connect two adjacent nodes of two adjacent layers in a clockwise direction. The layer cable and the stay cable constitute a continuous tension domain, which is located in the outermost layer of the whole structure, and wraps the arc rod and straight rod inside the structure. A compression whole composed of arc rods and straight rods, and layer cables and stay cables located on the outer layer of the structure together form a helical tension integral structure with good bending rigidity.
整个螺旋形张拉整体结构由以下参数唯一确定：结构中轴线的曲线方程γ、单体数m、每层底面的节点数n以及正n边形底面的外接圆半径R。所述螺旋形张拉整体结构的形式可随结构中轴线的曲线方程γ而改变，如图1-3所示的直线型、图10所示的圆环型和图11所示的任意曲线型等。当螺旋形张拉整体结构的形式为环状时，其每个结构存在2mn个节点，mn根弧形杆，2mn根直杆，m根层索，2mn根斜拉索。沿着螺旋形张拉整体结构中轴线，可将整体结构解构为m个单体。特别地，当螺旋形张拉整体结构中轴线的曲线方程γ为直线、圆等特殊曲线时，结构可解构成m个可重复单体。The entire helical tensioned overall structure is uniquely determined by the following parameters: the curve equation γ of the central axis of the structure, the number of monomers m, the number of nodes n at the bottom of each layer, and the radius R of the circumcircle of the regular n-sided bottom surface. The form of the helical tensioned overall structure can be changed with the curve equation γ of the central axis of the structure, such as the linear type shown in Figures 1-3, the annular type shown in Figure 10, and the arbitrary curve type shown in Figure 11. Wait. When the form of the helical tensioned overall structure is annular, each structure has 2mn nodes, mn arc rods, 2mn straight rods, m layer cables, and 2mn stay cables. Along the central axis of the helical tensioned monolithic structure, the monolithic structure can be deconstructed into m monomers. In particular, when the curve equation γ of the central axis of the helical tensioned overall structure is a special curve such as a straight line or a circle, the structure can be decomposed into m repeatable monomers.
螺旋形张拉整体结构可应用于连廊、景观桥和雕塑等场景。例如当中轴线的曲线方程为直线时，可用作建筑物之间的连廊。该结构极高的材料利用率和结构效率可以最大程度的减少连廊自重和材料消耗，而装配式的构成形式可以极大程度上减小现场施工难度。The spiral tensioned overall structure can be applied to scenes such as corridors, landscape bridges and sculptures. For example, when the curve equation of the central axis is a straight line, it can be used as a corridor between buildings. The extremely high material utilization and structural efficiency of the structure can minimize the self-weight and material consumption of the corridor, and the prefabricated form can greatly reduce the difficulty of on-site construction.
