Influence of space frame fabrication, installation method and span size on space frame structure selection

Image
The space frame structure is affected by many factors, such as space frame production, installation method, span size, steel index, etc., which all affect the determination of which space frame form to use to a certain extent. 1. For example, the joints are welded, and the space frame composed of plane trusses is more convenient to make than the space frame composed of quadrangular pyramids; the two-way orthogonal space frame is more convenient than the two-way oblique space frame and the three-way space frame. The frame is convenient; the quadrangular pyramid space frame is more convenient than the triangular pyramid space frame. 2. If the installation method does not adopt the overall lifting or hoisting, but adopts the strip or block installation, or adopts the high-altitude sliding method, select the two-way orthogonal positive space frame, the positive square pyramid space frame, and the positive evacuated square pyramid space. The three orthogonal space frames such as the frame

Three types of steel structures commonly used in gas stations

Image
Gas stations are common to everyone. The main material of gas stations is steel structure, and the space frame structure is a high-order statically indeterminate structural system. It has the advantages of small space force, light weight, high stiffness, and good seismic performance. The space frame is a manifestation of the space frame. The SAFS steel structure shares 3 forms of the space frame of the gas station below: 1. The space frame of the triangular pyramid system: it is divided into the triangular cone space frame, the evacuated triangular cone space frame, the honeycomb-shaped triangular cone space frame, etc. It is suitable for buildings with flat shapes such as rectangles, triangles, polygons and circles. 2. Space frame of hexagonal pyramid system: The space frame structure composed of heptahedrons is called the space frame of hexagonal pyramid system. Its basic unit is 6 chords, a hexagonal pyramid gas station space frame formed by 6 chords. 3. Space frame of cross truss

Power Machinery and Design in Steel Structure Building

Image
        Power machinery in steel structure buildings Power machinery can be divided into machines according to the power characteristics of operation. For example, the output of mechanical power such as metal cutting is not large, so it does not need to be considered. For equipment with particularly large operating power, the characteristics of power need to be considered. If the dynamic characteristics of mechanical operation are ignored, the use of power machinery will adversely affect the construction of steel structures. Power machinery and equipment will vibrate during use, which will have a serious impact on steel structure buildings, land and surrounding buildings, thereby affecting people's production and life. In addition, the scope of vibration is relatively wide, which may cause damage to some precision instruments and meters in the construction, affecting the measurement accuracy of the instruments and meters. Power mechanical equipment can be divided into impact-action

Steel Space Frame Segmented High-altitude Bulk Installation Technology Characteristics

Image
1. Simple operation and strong practicability The steel space  frame adopts the segment ed  high-altitude bulk construction, which is a steel space  frame construction method in which the outer expansion method is performed on the working platform from one side of the space  frame, and then the unit   grid  is lifted with a lifting tool for assembly until it is installed on the support.   Through the practical test of the project, it is proved that the steel space  frame adopts segment high-altitude bulk construction, which is conducive to meeting the requirements of engineering quality and construction period, simplifies the construction process, shortens the construction period, reduces the cost, and achieves better economy   benefits. Therefore, the technology has the significance of promotion. 2. Reduce construction accidents   probability Compared with the hoisting method and the high-altitude segmented splicing and sliding method, this method avoids safety accidents caused by he

Steel Structure Crack Generation and Analysis

Image
crack generation After the processing and installation of the steel structure of a petrochemical project, on August 16, 2022, during the inspection of the installation site, the construction personnel found that there were cracks in the web of the connection node between the lower support beam and the frame beam of the external heat collector at the 22m elevation of the project. After receiving the report, both the contractor and the installer conducted an on-site investigation. There were cracks in the welded joints of the primary and secondary beams of the platform steel structure. A repair plan was proposed and 100% flaw detected. Professional units were commissioned to conduct hardness testing and on-site sampling of the main materials of the cracked beams. analyze. In this re-inspection, a total of 15 similar beams were inspected, and only one crack was found. The crack occurred at the position of the connection weld between the main beam web and the secondary beam web (main beam
