Support arrangement of steel space structure

Image
  The support of the steel space frame structure includes peripheral support, point support, etc. Peripheral support is currently the most commonly used form of support, which is to put  the peripheral nodes of the space frame  on columns or beams. Point support means that the space frame  rests on an independent column, which have no connection with other structures.   The space frame  structure generally support by top chord . When the bottom  chord support is required due to the building function, vertical or inclined side trusses should be formed on the surrounding supports of the space frame  to ensure the geometric non-deformation of the space frame  and can  effectively   transfer the upper chord vertical load and horizontal load to the support.

Where can space frame structure be used?

Image
  The space frame  is composed of multiple rods connected by nodes. The construction method of factory production and site installation can shorten the cycle, reduce the cost and improve the economic benefits. More professional space frame  companies can provide better quality space frame s. And the material selection is better, which can make the overall cost-effective. And there will be more outstanding performance in terms of durability and aesthetics. To sum up, the space frame  structure can be applied to the roof of the station hall, the canopy of the stadium stand, the roof of the gas station, the coal storage shed, etc. In addition, the space frame  structure is more suitable for large-span roofs. Because it has the characteristics of good space force, high rigidity, steel saving, good seismic performance, small building height, and beautiful appearance. The space frame  structure is also commonly used in the roofs of construction projects such as l...

Three Methods of Space Frame Installation

Image
  What are the 3 methods of space frame  installation ? SAFS steel structure professional technical staff share with customers and friends:   1.  Splicing the entire space frame  directly, after the completion  of  the corresponding ceiling method to hoist the entire space frame  into the air, and then within a certain hovering time, weld the space frame  in the corresponding position and connect it with the whole  building . This method is faster  to install, but has higher requirements for operators. 2.  The method is relatively mild, the space  frame works directly at a high place, and the space  frame is installed bit by bit through the part that intersects with the building, that is, starting from the surrounding area and completing the work at the final center point. The schedule  is very slow, but the operation difficulty is also reduced a lot. 3. This method is mainly applicable to the quadrangular pyrami...

Characteristics of membrane structure  

Image
  Image from: https://www.safsteelstructure.com/ The following are the characteristics of membrane structure : 1.  Durability: Due to the appearance of high-strength and durable membrane materials, coupled with the application of tensi le  skills, the membrane structure will not be damaged in severe stormy weather. 2.  Artistic: its softness, curves, hardness and softness, the  rich shape, its whiteness and flawlessness, make us eye-catching and has a long   aftertaste. 3.  Light transmittance: good light transmittance (transmittance 20%). Exposure to sunlight will not produce yellowing, atomization , and poor light transmission. 4.  Weather resistance: The surface has a co-extrusion layer with anti-ultraviolet rays, which can absorb ultraviolet rays and convert them into visible light. 5.  Impact resistance: The impact strength of architectural membranes is 250-300 times of ordinary glass, 20-30 times that of acrylic sheets, and 2 times of t...

How to Distinguish Bolted Ball Space Frame And Welded Ball Space Frame

Image
Bolted ball space frame and welded ball space frame are the more common space structures in our building types, so how to distinguish between bolted ball space frame and welded ball space frame? SAFS steel structure will let you know about it. The difference between bolted ball space frame and welded ball space frame: The bolted ball space frame is mainly produced in the processing factory, and the welding seam treatment is basically completed in the processing factory. The length of the steel pipe is easy to control, and it can be directly assembled when it arrives at the construction site. It is suitable for all structures, especially the modeling structure, which can ensure construction accuracy and the consistency of the structural modeling. There are many construction methods, the construction cost and measure cost is lower, and the construction progress is fast. Welded ball space frames are processed in the factory, and the welding seam treatment is mainly processed at the const...

How to ensure the quality of the bolt ball space frame

Image
The space frame structure is widely used in large hangars, stadiums, exhibition halls, theaters and various industrial plants. In modern construction, the requirements for the construction plan of the bolt ball space frame are relatively strict, so how to ensure the quality of the bolt ball space frame during the design, production and installation process? One is material selection. The selection of materials needs to meet the standards and control the hardness of the materials. The second is design. It needs to be carried out in strict accordance with national standards to achieve excellence. Third, after the installation of the bolt ball space frame is completed, it is necessary to carefully check the rust, drilling, and oil stains on both sides of the connecting platform and the welding seam within the range of 30-50mm, which needs to be removed in time. Fourth, after the cleaning is completed, it is necessary to conduct ultrasonic testing on the building.In the event of non-confo...

Brief introduction of corrosion and anti-corrosion of space frame steel structure

Image
  Because the space frame  steel structure has the advantages of good mechanical properties, strong load-bearing performance, simple manufacturing, easy to adopt industrial production, short construction and installation period, and good sealing performance, it has been widely used in national economic construction, such as l ong -span structure (coal bunker , stadium roof trusses, etc.), light   space frame  steel structures (large and medium-sized workshops), high-rise buildings (commercial buildings, office buildings, etc.). However, during the use of steel structure, and the environmental medium in which it is prone to biochemical, electrochemical or physical effects, resulting in the deterioration of the material and the destruction of steel structure failure, people often called the corrosion of steel structure.  People have realized that the steel space frame  structure used by humans is rarely damaged due to pure mechanical factors (such as tension...
