LF large span steel structure solutions

  As the environmental storm continues, many open-air bulk cargo yard due to dust pollution problems were shut down or closed for rectification, then how to implement the whole closure of the site to save the most money? The use of existing wind-proof dust wall to transform the fully enclosed material field. The main structure of the yard closed adopts the steel structure of the space frame, the maintenance structure adopts the steel structure color plate and the glass steel light belt closed, the shape is space frame type, flat-type mainly, the use of column-free design, equipped with fog gun dust suppression and water spray device, to achieve all material into the shed, reduce the loss of material in the operation, prevent dust suppression. Wind-proof dust wall transformation full-enclosed silo technology to make full use of the existing field of wind suppression dust wall, the use of a new design concept, after the transformation of the fully enclosed silo not only to achie...

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...

  The space structure is exposed to the air for a long time. When the air humidity is too high, a water film will form on the surface of the steel grid, which will corrode the anti-corrosion layer and embroider.Especially in seaside cities, heavier salty places, which are more likely to cause rust on the space frame. Therefore, the rust removal and anti-corrosion maintenance works are more important. When the anti-corrosion layer of the space frame can no longer continue to work, it is particularly important to carry out the rust removal and anti-corrosion maintenance project.The three main points of the anti-corrosion maintenance: good surface rust removal work, high-performance materials, and the thick anti-corrosion and anti-rust coating. Surface treatment is very important. Good  treatment  work can make anti-rust effect 3-5 times better , under the same paint, the same environment, and the same coating thickness. The stains and rust spots on the surface of the steel...

  Why the space structure  is the best choice for large-span buildings? Because the space structure  can be realized  with small rods to meet  a large-span structure . The grid structure occupies a small space, can effectively use and save the space. Space structure has the characteristics of triple stress, which can withstand various stress effects. Generally, the internal force structure can be adjusted according to the force requirements of the space structure, which has high safety. For the space structure, the aerial crossing members both bear the force and play a supporting role, thereby ensuring the integrity of the grid engineering and ensuring the stability. The space structure has high rigidity, can bear symmetrical load and concentrated load, and has good seismic resistance .

  Steel space structures  ha ve  been widely used, and only space structures that meet safety standards can be used in buildings. The first thing to test  is the material used for space structure. Although they are all steel, steel can also be divided into many kinds. Different steel adoption will affect the quality of the entire space frame, so here is also one of the focus of quality inspection. The next step is to check whether the design of the entire steel frame is reasonable. This is a very important product of spatial structure, if the design is defective, it will not take long to produce quality problems, and even seriously threaten the lives of people . Therefore, the design drawings are also required to go through the review of the examination before implementation phase. The third is to be in the installation process of on-site supervision, supervision of the order of installation and methods, whether the site has been cleared to achieve a safe environment...

The construction method of large space frame structure is constantly innovated.With the increasing diversity and span of space structure, the construction method of space frame  structure needs to be innovated, and the construction technology has also been developed.Construction technology is very important in the construction of large space structure. Only reasonable construction scheme and scientific analysis can guarantee the safety and economy of the structure. Theoretical research on spatial structure has been further developed.With the continuous innovation of space structure system and form, the theory of space structure will inevitably develop in depth and breadth.Earlier studies had more focus on static under the action of shape and structure analysis method, and the simplified method such as quasi plate method, the finite difference method study, after gradually from static to dynamic, from linear to nonlinear, on the spatial structure of the static and dynamic stab...

On May 17, 2020, Liuzhou Converter Station in Liuzhou City, responsible for the construction of China Southern Power Space Structure Guangxi Transmission and Transformation Construction Co., Ltd., successfully completed the last space structure lifting and capping task. This hoisting project uses a computer-controlled hydraulic lifting system to set up 12 hoisting points. Through eight trips, the space strutcure weighing 730 tons and covering an area of 7,400 square meters is hoisted to a predetermined height of 32.83 meters and safely installed in place. After the lifting of the space structure of the valve hall this time, it will be built into a complete valve hall on the basis of it, which will provide a good environment for the operation of the converter valve in the later period and help it carry out the power transmission at a long distance. The lifting work of the space structure was completed successfully, marking the end of the construction part of the civil A standard. ...
