Precautions for space frame processing
Precautions for space frame processing Now everyone is using the space frame structure, but when processing the space frame, you should pay attention to the operation of the space frame processing. Its quality will affect the stability of the entire structure, so in order to ensure the processing of the space frame. When the processing is completed successfully, everyone must pay attention to the following points:
1.Avoid some illegal operations when processing the space frame, such as the processing of simple steel columns, which causes the frame system to be weak and lead to collapse. At the same time, the height of the anchor bolts in the space frame construction is inconsistent, and the positioning size of the bolts is deviated, which causes the deviation of the steel column in the processing process, which will cause the entire project to deviate.
2.The quality of the bolts in the space frame processing is unqualified, and a stable frame system cannot be guaranteed during the construction process. Therefore, the bolts with quality problems should not be added to the space frame engineering. The tightening torque must be strictly calculated to reduce Deviation to avoid affecting the perforation operation during the construction process.
3. The phenomenon that the space frame processing is not in place should be eliminated. At the processing site I must ensure that the customization is in place to achieve the requirements of the space frame engineering for customization, avoid more air holes and affect the overall quality of the space frame, and at the same time follow the overall. The construction process requires construction to prevent the modification of the project from affecting the entire project.
4. The allowable deviation of pipe blanking is ±1.00mm, the perpendicularity deviation of the end face to the pipe axis is ≤0.005r, the nozzle curve deviation is ≤1.00mm, and the allowable deviation of grid processing: when the diameter of the ball is d≤120mm, Deviation ≤1.5mm, when d>120mm, deviation ≤2.5mm, the angle and flatness difference between the center lines of two adjacent bolt holes & plusmn; 30 minutes, the steel surface should be sandblasted to remove rust and surface treatment as required. The degree of sandblasting should reach Sa21/2. After the test bench, apply the anti-rust primer twice. The anti-rust primer adopts Hongdan anti-rust paint.
5. Material procurement should strictly follow the design requirements and choose products from manufacturers with good reputation and reliable quality. LF is professional manufacturer and engineering company for space frame and steel structure project with full capability of research, design fabrication, construction, supervision service for oversea project.All materials exported by LF have quality assurance certificates and meet the standards of various countries
LF space frame processing and leaving the factory must be strictly tested, and the factory certificate, production record and inspection report shall be attached. The space frame processing must pay attention to the above points, and the quality can be guaranteed on the basis of smooth progress. For those processing conditions that need to be paid attention to, as long as it is within the allowable deviation range. LF hope everyone pays attention to the scientific accuracy of construction operations in processing and can improve the safety factor of the structure.
