In recent years, dome modeling is no longer a single plane model, a diversified, heterogeneous, large span of the direction of development, unique shape of the glass daylighting dome transparent crystal, extremely architectural effect, to meet the use of function while increasing the aesthetic feeling of the building, is adopted by more and more architects. 1 Project Overview Business Street Project, core area of Nanning Wuxiang New District, skirt house surface lighting project, the outer contour is ellipsoid, the long axis is 60m, the short axis is 30m, the height is 10m, and the glass panel area is about 2200m". The lighting dome has large span, large volume, and difficult construction. 2 analysis of key points and difficulties in construction (1) The shape of the outer contour is a complex warping surface (ellipsoid), and triangular panel splicing is adopted. There is no panel with exactly the same shape in the whole project. The traditional blanking time is long and the const...

Large-span steel structure engineering has been widely used in bridges, marine engineering, gymnasiums, exhibition centers, workshops, airport terminals and other building structures, such as the current landmark buildings in China: Shanghai "Oriental Pearl" TV Tower, Changchun Nanling Ten Thousand People Gymnasium; foreign ones such as Sydney Aquatic Center, Japan Fukuoka Gymnasium, etc. Especially in recent years, the application of new materials and new technologies has promoted the development of the span and building scale of large-span steel structure buildings. In the construction of some large-scale steel structure buildings, not only structural selection, section optimization, construction factors and cost, but also Gradually consider higher-level requirements, such as coordination with the surrounding environment, multi-level compliance with economic and cultural life, humanized requirements, architectural aesthetics, etc. At the same time, relevant personnel shoul...

  According to "Technical Regulations for Spatial Structure ", the installation method of spatial structure should be comprehensively determined according to the type, stress, and structural characteristics of the structure, under the premise of ensuring quality and safety, in combination with schedule, economy, and technical conditions of the construction site. , there are 6 main types: 1) High-altitude bulk method. Use a crane or a hoist to hoist small units or rods for assembly at high altitudes. It is suitable for various types of spatial structures assembled with full supports, especially for bolted, pinned, and other non-welded connection structures. 2) Slitting or block installation method. The space frame structure is divided into strip-shaped units or block-shaped units and connected to a whole at high altitude, which is suitable for spatial structures with small changes in the stiffness and stress conditions of the structure after segmentation. 3) Slip method. It is...

  Due to its special use function, the hangar has extremely high requirements on space and force. The current design scheme mostly adopts the welded ball   space frame with a large span , good force, and low self-weight. Ground assembly and overall lifting are the most commonly used lifting methods for large-span welded ball space frames. Therefore, controlling the quality of the ground scattered welding and the welding quality of high-altitude supplementary rods is the key to ensuring the safety of the construction space frame structure. 1 Project overview 1.1 General overview of the project Air China Base Project No. 101  Maintenance Hangar  Project is located in Chengdu Tianfu International Airport. The building covers an area of 20,562 square meters, with a total construction area of 28,447 square meters and a total building height of 37.65 meters. A330 series aircraft are parked side by side, which can guarantee the warehousing maintenance of A350-900 and take i...

  1. Project overview The Feixian General  Airport Hangar  Project is located in Huyang Town, Feixian County, Linyi City, Shandong Province. The project includes a general aviation complex, an airport professional building, a general aviation service center, 1⋕ hangar, 2⋕ hangars, 3⋕ hangars, 4⋕ hangars, There are 10 units in total, including crossings and gatehouses. Among them, the hangar part is designed as a reinforced concrete bent-frame column and space frame roof system, and the ball joint grid frame of the hangar roof is a rectangle as a whole. About 3870m; 2⋕ hangars and 4⋕ hangars are 43m wide and 60m long, with an area of about 2580m2. The ball joint  space frame  adopts the inclined quadrangular pyramid space frame structure, and the joints are mixed joints of bolt balls and welded balls. The weight of the 1⋕~4⋕ hangar grid is about 680t, supported by the bottom chord, and the height is 2.50~6.00m, which is a regular space frame. prefab airplane hang...

  Beijing University of Science and Technology   Gymnasium   (Judo and Taekwondo Competition Hall for the 2008 Olympic Games) is located on the campus of the University of Science and Technology Beijing. The roof span of the competition hall is 76.8m in the east-west direction and 105m in the north-south direction, and the roof span of the swimming pool is 60m in the east-west direction and 30m in the north-south direction. The lower structure (including the partial basement) system, the competition hall is a frame structure with 4 reinforced concrete small cylinders, the swimming pool is a reinforced concrete frame structure below the second-floor platform, and the steel pipe column support space frame above the platform. Stadium with  the advantages of the design of the space frame The  space frame span  of the competition hall is large, and there are hanging equipment layers along the east and west sides. The gable walls at the north and south ends are h...

1 Pr stadium roof oject overview   The Yinglong Middle School Gymnasium has a total of 1 floors, and the height from the ground to the roof is about 14.9m. The roof of the gymnasium adopts steel space frame  construction technology, with arching on both sides, bolt ball joints, positive quadrangular pyramid space frame , multi-point support on the upper chord, the maximum installation height is 12m, the maximum span is 29.1m, the sag height is 2.188m, and the area reaches 1260 ㎡, the total weight is about 54t.
