Spherical space frame is a kind of space frame structure with simple structure and beautiful modeling, which is widely used in stadiums, exhibition halls, museums and other fields. Its design principle and construction process include the following aspects.
Structural Principle: The spherical space frame of SAFS Steel Structural Engineering Co., Ltd. adopts the arrangement and combination of triangles and quadrilaterals, which creates a stable structure in terms of mechanics and can withstand an even distribution of force. Through the connection between the rods, a stable spherical structure is formed.
Material selection: The spherical space frame is generally made of high-strength steel or aluminum alloy. These materials have a certain compressive and tensile strength, and can meet the use of spherical space frame requirements.
Load analysis: The designer needs to analyze the loads that the spherical space frame is subjected to, including self-weight, wind load, snow load and so on. Determine the structural strength and stability of the spherical space frame through load analysis.
Foundation treatment: the foundation of the spherical space frame needs to be treated before construction, including the leveling and reinforcement of the foundation to ensure the stability and bearing capacity of the foundation.
Erection of temporary supports: In order to facilitate the construction, it is necessary to erect temporary supports to support the spherical space frame. The height and form of the temporary support is determined according to the actual situation, and is generally built by a combination of steel pipe and scaffolding.
Making prefabricated nodes: Before the construction of the spherical space frame, prefabricated nodes need to be made, these nodes are the key to connecting the bars together. Prefabricated nodes are generally welded or bolted to ensure the stability and reliability of the nodes.
Installation of rods: According to the design drawings, install the prefabricated nodes and rods one by one on the temporary supports. According to the construction sequence, gradually assemble the rods to ensure the structural accuracy and stability of the whole spherical space frame.
Carry out the installation of the sphere roofing: after the installation of the rods, the installation of the sphere roofing needs to be carried out. The roof is generally made of special materials with certain light transmission and waterproof performance to maintain the overall beauty and function of the spherical space frame.
Improvement of detail processing: in the construction process of the spherical space frame, it is necessary to carry out detail processing, including the reinforcement of the nodes, the adjustment of the rods, etc., to ensure that the structure of the entire spherical space frame is stable and harmonized with the surrounding environment.
Construction quality check: after the construction of the spherical space frame is completed, a quality check is required. Including structural strength, appearance quality, waterproof performance and other aspects of the inspection to ensure that the construction quality of the spherical space frame in line with the relevant standards.
Completing the maintenance of the spherical space frame: after the construction of the spherical space frame is completed, you need to carry out daily maintenance work. This includes cleaning, painting, inspection, etc. to ensure the long-term stability and beauty of the spherical space frame.
Through the above design principle and construction process, it can ensure that the spherical space frame has good performance in terms of structural strength, stability and aesthetics. At the same time, the standardization and meticulous construction process can also ensure the construction quality and service life of the spherical space frame.
