Bolted ball mesh frame is a space grid structure that has a number of significant features in the construction field.
(1)Reasonable space force
Bolted ball mesh frame is a spatial integral structure, each rod is connected to each other through the bolt ball node, forming a three-dimensional force system. When bearing loads, it can effectively transfer the vertical loads of the roof (such as self-weight, snow load, live load, etc.) and horizontal loads (such as wind load) to the supporting structure. This spatial force characteristics make the grid structure uniform force, stress distribution is reasonable, can give full play to the mechanical properties of the material, to avoid local stress concentration.
(2)High stability
Due to its spatial structure characteristics, the bolt ball net frame has good stability. Even when it suffers from large lateral force (such as strong wind), it can rely on its own space structure system to resist deformation through the co-operation between the rods. Moreover, under the action of earthquake, its spatial stiffness can effectively reduce the amplitude of structural vibration, so as to ensure the safety of the building structure.
(1) High degree of factory production
The rods and bolt ball nodes of bolt ball mesh frame can be accurately prefabricated and processed in the factory. The length and cross-section size of the rods, as well as the size of the bolt ball and the location of the screw holes can be standardised according to the design requirements. This factory production method can ensure the quality of components, and improve the production efficiency and reduce the workload of on-site construction.
(2) Fast and flexible on-site installation
On-site installation, the constructor only needs to connect the prefabricated rods and bolts through high-strength bolts. This connection is simple and convenient, and does not require complex welding process, which greatly shortens the installation period. Moreover, the shape and size of the net frame can be flexibly adjusted according to the actual situation during the installation process, and the requirements for the construction site conditions and construction space are relatively low, so it can adapt to a variety of complex architectural shapes and construction environments.
(1)Rich geometric shape
Bolted ball grid frame can be formed according to the requirements of architectural design, various geometric shapes, such as flat plate shape, curved surface shape (such as spherical, parabolic shape, etc.). These different geometric shapes can create a unique appearance effect for the building, so that the building can become a landmark building with artistic value while meeting the functional requirements.
(2) Strong sense of transparency and lightness
As the grid structure is a space system composed of rods, compared with the solid structure, it has a transparent visual effect. This sense of permeability can make the internal space of the building more open and bright, and at the same time, give people a sense of lightness, especially suitable for sports venues, exhibition halls and other large-scale public buildings, to create an open, modern building atmosphere.
(1) High material utilisation rate
Bolted ball grid structure is able to minimise the amount of material under the premise of meeting the requirements of structural strength and stability by means of reasonable rod arrangement and force analysis. Its spatial stress characteristics enable the material to be fully utilised, avoiding material waste.
(2) Lower maintenance cost
In the long run, the maintenance cost of bolted ball grid structure is relatively low. Due to its simple structure, the rods and nodes are easy to check and repair, and the structure has better durability under normal use, which does not require frequent large-scale repair and maintenance, and can save costs for the operation of the building.
