The distinction between steel structure and space frame

 space frame

Space frame structure is a kind of steel structure, which belongs to steel structure.However, the difference between the space frame structure and the steel structure are the way of connection, the use of structural materials, the structural form and the structural system:
Connection type:
1. The nodes of the space frame structure are regarded as hinged, usually connected by bolts;
2, the joint of steel structure as a rigid contact, usually by welding.
From the materials and forms used:
1, the steel structure is refer to structure material
2, the space frame is refer to structural form
The space frame can have the steel space frame, the aluminum alloy space frame and so on, but commonly in the steel space frame.
Steel structure in addition to the steel grid, there are steel frame, steel portal frame and other forms.
From structural system:
1. The steel space frame belongs to the spatial structure system, so the overall force and spatial deformation should be considered in the calculation;
2. The steel structure truss is similar to the plane steel truss, which belongs to the uniaxial stress. as long as the strength and stability in the plane are calculated, the stability outside the plane is mainly borne by bar and tie bar.   
3. Compared with the steel grid structure, the steel truss structure eliminates the lower chord longitudinal rod and the grid ball joints.Truss structure is developed on the basis of steel space frame structure. Compared with the space frame structure, it is economical to use the truss structure.

Liuzhou Liubei converter station power station construction

图片
On May 17, 2020, Liuzhou Converter Station in Liuzhou City, responsible for the construction of China Southern Power Space Structure Guangxi Transmission and Transformation Construction Co., Ltd., successfully completed the last space structure lifting and capping task. This hoisting project uses a computer-controlled hydraulic lifting system to set up 12 hoisting points. Through eight trips, the space strutcure weighing 730 tons and covering an area of 7,400 square meters is hoisted to a predetermined height of 32.83 meters and safely installed in place. After the lifting of the space structure of the valve hall this time, it will be built into a complete valve hall on the basis of it, which will provide a good environment for the operation of the converter valve in the later period and help it carry out the power transmission at a long distance. The lifting work of the space structure was completed successfully, marking the end of the construction part of the civil A standard. ...

Safety management method of space frame construction

图片
1.Provide safety education and training to workers and relevant safety management personnel before the construction of the space frame structure, complete technical safety disclosure, strengthen safety awareness and safety responsibility awareness; 2.When working at height, workers should be reminded to take protective measures, such as properly wearing safety belts and helmets; 3.In the cross work of network structure, communication should be done in advance without affecting each other and the work should be completed in an orderly manner; 4 . I n bad weather, can not construction do not construction, to ensure their own safety; LF is a professional manufacturer and engineering company for space frame and steel structure projects.Do you have a construction project we can help with?

Shenzhen Bay Sports Center

图片
The spatial  structure is particularly favored by large-scale stadium buildings because of its advantages of reasonable stress, beautiful shape, complex free three-dimensional space and minimum internal support mutual interference. The integrated design of the Shenzhen Bay Sports Center places the stadium, gymnasium and swimming pool under a white giant grid-like steel structure roof. The soft-line roof is like an incubator for sports athletes who break the cocoon and rush to the world. The novelty and unique shape are similar to the design method of "Bird's Nest". The unique structure of "One Field and Two Pavilions" makes the construction of "Spring Cocoon" more difficult than that of Bird's Nest . The steel structure of the Shenzhen Bay Sports Center is a large-span complex space structure. The steel structure roof is composed of a single-layer reticulated shell (stadium, large tree square and other public areas), a double-layer curved ...
