LF large span steel structure solutions

Space frame structure is the common roof form of large stadium, industrial workshop and dry coal shed. The method of s pace frame structure is to rely on the force of the steel itself, the steel columns are connected together with bolt ball to support each other staggered, the net forms various roof space. From the meeting room of a few meters to the industrial workshop with a span of several hundred meters, it ’ s all the suitable scope  of space frame  structure . The space frame structure construction speed is fast, the size and shape of its component are a large number of the same, can be produced in batches in the factory, industrialized production for more than 80% of the whole project, and good quality, high efficiency, not compete with civil construction site at the same time, so the site workload is small, shorten the construction period.

The total construction area of Zhengzhou Olympic Sports Center is 570,000 square meters, the main stadium can accommodate 60,000 people, in addition to the main stadium, the Olympic Sports center also contains a large Class A stadium and a class A natatorium, the stadium can accommodate 16,000 spectators, the natatorium can accommodate 3,000 spectators.The outer roof of zhengzhou Olympic Sports Center is made up of metal roofing and solar panels. Seen from the outside, the Olympic Sports Center and the other two venues look like giant sparkling vitreous bodies embedded in the vicinity of the South-to-North Water Diversion Canal, forming zhengzhou new sports center together.   "Two pavilions at one Venue" " of the steel structure used a total of 47000 tons of steel, steel and the "bird's nest" stadium, but, unlike the "bird's nest" all steel structure roof, Olympic sports center of zhengzhou adopted the "giant triangle truss +  facade tru...

Construction of the swimming pool and gymnasium of Qingyuan Olympic Sports Center started in September 2019. It is the venue for the 16th Guangdong Provincial Games in 2022. The steel structure is about 6,000 tons. The stadium project of Qingyuan Olympic Sports Center is a key project of Qingyuan City and Guangdong Province. It has the characteristics of large amount of work, tight schedule and difficult construction.   The construction content mainly includes a 30,000-seat stadium, a 9,000-seat gymnasium and a 2,000-seat swimming pool. The project covers an area of 640,000 square meters, of which 290,000 square meters are occupied by waters, roads, and public green spaces. The planned construction area is 350,000 square meters and the total construction area is 130,000 square meters. The main truss of the stadium roof steel structure is a willow-shaped inverted triangular space tube truss，total ly  ten trusses, a maximum span of 84 meters, and a single truss weight of 118 to...

Steel space frame  structure ball joints are divided into two types: welded ball and bolted ball. The bolted ball is fastened by high-strength bolts, and the welded ball is connected by on-site welding. The following points need to be paid attention to when deepening the design of the ball joint: (1) There are differences among the manufacturers of bolt ball joint fittings. The fitting data should be obtained before deepening. (2) The materials of steel balls, high-strength bolts, sleeves, fastening screws, taper heads or sealing plates in bolted ball joints shall meet the requirements of design and specifications. (3) The grades of high-strength bolts in bolted ball joints should be selected according to specifications. (4) The diameter of the bolt ball should ensure that adjacent bolts do not collide in the ball and should meet the requirements of the sleeve contact surface. (5) The cone or sealing plate at the end of the rod in the bolt ball joint is connected by welding, and t...

  Tensioned membrane structures use bracing rods or cables to prestress the membrane material to form a stable curved surface to maintain the structural form of the building.This form of membrane structure can give full play to the properties of membrane materials, and has a high degree of physical plasticity and structural flexibility, which can best reflect the artistic creativity of membrane structure materials. Case: Weihai Stadium It covers an area of about 40,000 square meters and can accommodate 30,000 spectators. The stadium stands are reinforced concrete frame structure, and the stand cantilever shed is a typical tensioned membrane structure . LF is good at stadium gymnasium projects.

  The Skeleton membrane structure is composed of its own stable skeleton system and membrane body, which determines the architectural form, and membrane body is the covering.The prominent characteristics of the skeleton membrane structure lie in: membrane is not a necessary structural unit to maintain the existence of the structural system, and it is not just a simple roofing system, but gives full play to the lighting building function and high strength stress characteristics.Skeleton membrane structure is one of the most commonly used forms in membrane structure engineering.

  The supporting node is the tie that connects the steel space frame structure   to the enclosure structure, and is often arranged on the upper chord and side of the space frame . The deepening design of support nodes need to pay attention to the following points: (1) On the premise of meeting the force requirements, use high-strength bolts as much as possible for the connection between the support and the ball to reduce the amount of high-altitude welding on site. (2) The support top plate is best to be set in a circular shape to ensure that the support can be positioned and installed when rotating 360 degrees along the rod axis. (3) When the support height is large, in order to ensure the lateral stability of the support, it is best to install diagonal braces.
