Types and characteristics of spherical grid nodes

2025-05-05

In large-scale building structures or bridge projects, spherical grids, as an important spatial structural system, are increasingly respected and applied due to their unique design and superior performance. As a key part of the entire structure, the nodes of the spherical grid not only determine the strength and stability of the grid, but also directly affect the beauty and architectural style of the entire structure. Therefore, in-depth discussion and analysis of the types and characteristics of spherical grid nodes has important theoretical and practical significance.

 

  1. Types of spherical grid nodes

(1) Tension spherical grid node: The tension spherical grid node refers to a structural system composed of long rods, short rods and nodes. Its main force-bearing mode is to apply tension to the outside through the long rods to ensure the stability of the entire spherical grid. In actual engineering applications, this structural form has the advantages of short rod length, simple node arrangement, flexible shape, etc. At the same time, it can reflect a strong sense of modernity and technology. It is a structural system commonly used in large-scale building structures.

(2) Reaction spherical grid node: The reaction spherical grid node refers to a structural system composed of long rods, short rods, nodes and supports. Its main force-bearing mode is the inward pressure through the long rods, and the reaction force needs to be transmitted downward through the supports to ensure the stability of the entire spherical grid. This structural form can reflect the mechanical properties of the material to a certain extent and is a structural system commonly used in mechanical teaching and scientific research.

(3) Hybrid spherical grid node: The hybrid spherical grid node refers to a structural system composed of rods and nodes of different forms. This structural form makes up for the shortcomings of a single form of spherical grid and can be more flexible and superior in shape and force performance. At the same time, the design and construction of the hybrid spherical grid node is also more complicated, and it is necessary to consider factors such as different materials and rod lengths. Therefore, a higher level of technology and technical experience are required in practical application.

  1. Characteristics of spherical grid nodes

(1) Spherical grid nodes have good weather resistance: Spherical grid nodes are generally made of high-quality materials such as aluminum alloy and stainless steel, with good corrosion resistance and wear resistance, and can maintain good surface condition and performance in harsh natural environments.

(2) Spherical grid nodes are easy to install: Spherical grid nodes have various combinations and can be assembled and connected by bolts, welding, sleeves and other methods. They have the advantages of easy installation, adjustment and maintenance.

(3) Spherical grid nodes have strong bearing capacity: The design and manufacture of spherical grid nodes adopt advanced numerical analysis and simulation technology, which can meet the requirements of long-term use and withstand harsh environments, loads and other factors.

(4) Spherical grid nodes have good aesthetics: The shape and design of spherical grid nodes are flexible and diverse, which can meet the aesthetic requirements of different environments and needs, have good aesthetics and visual effects, and become a fashion trend in modern architecture.
