LF large span steel structure solutions

The ground floor of the 55,000-seat National Stadium will be completely covered by a vault with a total span of more than 310 meters.The shape of the dome structure transforms it into a naturally ventilated stadium. The dome will also provide 20,000 square meters of movable area, which will protect the stadium's sports floor and spectator areas during heavy rainfall. When completed, the roof of the stadium and the roof of the adjacent stadium will form a distinct difference, appearing together in the Singapore skyline.The stadium is capable of hosting a variety of sporting events including athletics, football and even soccer.Next to the stadium, there are two multipurpose indoor stadiums with a capacity of 3,000 spectators each. 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? We are always ready to help you!Website: www.cnxzlf.com  

  The first drafts and sketches of the Glass Igloos were outlined already on year 1993 by Architect Esko Lehmola, but suitable manufacturer and related machinery was not found. The next drafts on year 2005 were showing that addition to glass, another material is needed. The development work continued on year 2013 and another material was found to be composite with insulation which can be formed accordingly. Also suitable manufacturer and machinery for the glass itself was now available. The general design of the Glass Igloo was determined to be constant half ball shape without sharp seams between each of the glass. The idea was discussed further with advanced glass companies in Europe and they confirmed that the current design is aesthetic can be built. The general design consists of symmetrical glass segments and one skullcap glass on the top. All the glass seams are filled silicone or comparable material. The seams between each glass are relative thin and the glass surface forms...

The structure of reticulated shell can be classified according to the arrangement of the rods: single-layer reticulated shell and double-layer reticulated shell. Generally speaking, single-layer reticulated shell can be used for small span (generally below 40m), and double-layer reticulated shell can be used for large span.  D ue to less bar s , light weight, simple node, convenient   construction,  s ingle-layer reticulated shell has a better technical and economic indicators, but single-layer reticulated shell surface  has a p oor external stiffness and stability, a variety of factors will   affect  the internal force and deformation of the structure  obviously.   Thus it should be  noticed including, the layout of structure bar, roofing materials  choosing , the determination of calculation mode, i mplementation of structural measures , c onstruction and installation of the structure. a . The bars of reticulated shell structure mainly...

glass dome structure In the connection between the main parts of the steel beam and the steel beam of the dome structure , the traditional construction method has two forms. One is the direct welding on site .   Second, the plate is fixed and then welded on site. C rane lifts the steel beam to the joint of another steel beam and the person welds it at high altitude and grinds it flat on site.   Both of the above two methods require welding operation, and on-site welding has the following disadvantages: 1) welding operation requires on-site welding machine to pull wires, which is of high labor intensity and slow construction speed, time-consuming and laborious, and also increases labor cost;2) high-altitude welding is dangerous, easy to cause casualties and cannot guarantee welding quality;4) due to welding deformation and errors, the lighting glass above cannot be processed correctly. Generally, the frame is welded and installed, and the glass is ordered and produced afte...
