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 ...

Bulk method for installation of  space frame 

图片
The installation of the space  frame is done in bulk.The operation process is as follows: setting out, checking the line, installing the lower chord plane grid, installing the upper chord inverted triangle grid, installing the lower chord positive triangle grid, adjusting, fastening, welding and acceptance of supports, checking the concrete strength of the column top, checking the specimen report. After qualified, the line setting and acceptance of the column top can be carried out at high altitude. Installation method of space frame : Before the space frame assembly unit node, the parts must be checked repeatedly, and the Numbers should be put in the seat in order.After each unit node is assembled, the tightening degree of the bolt shall be checked with the afterhand.After a certain area is installed, the lower chord is supported with temporary support to correct its lower chord elevation.After the installation of the entire network, re-check the fastening bolts, and remove ...

Structure and form of space frame node

图片
  In the space frame structure, the joints connect members and transfer roof and crane loads, the grid is also part of the space bar system, and there are at least 6 or as many as 13 bars connected to a node. This makes node design more difficult. The number of nodes in the space frame is large, and the amount of steel used by the nodes accounts for 1/5~1/4 of the total amount of steel used by the whole space frame members. The reasonable design of nodes is directly related to the safety degree, fabrication and installation, project schedule, steel quantity index and project cost. Node design is one of the most important steps in space frame  design The node structure of the space frame  should meet the following requirements : (1)  Reasonable force, clear transmission force, be sure to make the node structure and the calculation assumptions conformed  as much as possible, make the node safe and reliable ; (2)  Ensure that the junction bar intersects at on...
