  Jiuzhou   Gymnasium Roof   in Mianyang became the focus of the media when it played an important role as an evacuation center and emergency command center during the 2008 Wenchuan earthquake relief process. The upper part of Jiuzhou  Stadium is a steel structure roof , with four floor-to-ceiling steel structure arches as the main load-bearing structure, and three-dimensional or plane trusses as secondary structures between the arches, matched with the support system, which is novel and unique. The lower part adopts reinforced concrete frame-shear wall structure, without deformation joints, four stairwells are reinforced concrete tubes and composed of four different concentric circle layout forms of an oval plane. The building with its unique  structural design  concept and advanced seismic fortification thinking, to ensure that it is still standing under the action of the earthquake, the main structure and support are not obvious damaged, only the local s...

  In the past 30 years, various   large span space steel structures   have been developed rapidly at home and abroad. As nodes play a crucial role in space structure, scholars have developed different types of space nodes to adapt to different structural forms and stress requirements. Common space joint types include welded hollow ball joint, bolted ball joint, cast steel joint, bolted ball column joint, end plate joint and so on. Due to the high cost of labor and inspection, field welding is rarely used in foreign projects, and bolts are used to connect most nodes. The main node of the steel structure of the prayer hall dome of the Great Mosque in Gama, Algeria, is prefabricated in the factory with joint domains and rods and connected with end-plates by high-strength bolts on site. The Great Mosque of Jiama is located on the central axis of Algiers, the capital of Algeria, beside the Mediterranean Sea, with a construction area of 400,000 square meters. The minaret is the...

  The bolted ball is inseparable in the process of space frame   processing. It is one of the important accessories. It can assume the role of connection and support in the structure. If the quality of the bolt ball is unqualified, it will affect the processing quality of the space frame . It is an indispensable and important part, let's take a look at the specific introduction. The diameter of the bolted ball space   frame should be controlled within a reasonable range to reduce errors.  When the diameter of the rod is large, it should be connected to the cone.  The bolt space frame is arranged flexibly, the parts are connected with high-strength bolts, the construction period is short, and it can be mass-produced. Therefore, it is necessary to ensure that the thickness of the node shell and the shell are sufficiently large. Generally speaking, the thickness of the shell wall and the thickness of the cover should not be too different. From the perspective of ...

  Space   frame processing is very meticulous work. The quality of the space   frame is not good. Most of them appear in this process. As long as the processing is completed, it can bring you a very good quality effect. It can be said that a very powerful material is used , which is a n important role in itself. First of all, look at the structure of the entire space frame   processing to see if the steel pipes are arranged neatly. If it is found to be disordered or missing, the processing will not go smoothly and it must be a perfect product.  Many space frame   structures have a stable effect on various occasions, and there will be no unfavorable phenomena such as looseness, abnormality, and failure, and there is a high demand for space frame   construction.  Secondly, we can also see the welding performance of space frame processing. Space frame welding is a kind of welding fusion of buildings or products. This technology is indispensable for ...

Bolt-ball joint space truss is a new type of roof bearing structure, which belongs to multiple statically indeterminate space structure system.   The bolt-ball node network frame has the following characteristics: (1) Large space stiffness, good anti-expansion performance. (2) steel and save, low project cost. (3) Flexible selection, according to the requirements of the building, design a variety of curved surfaces, modelling. (4) Components can be mass produced in the factory, which is convenient for construction, and the quality and progress of the project are guaranteed. (5) The force is clear, the rod has strong regularity and the grid is uniform. (6) the distance between the grid nodes is small, there is a certain space between the upper and lower chord layers, the roof and other supporting dishes are convenient to install, and the comprehensive cost of the project is low.
