Steel Space Frame Structure Supplier - SAFS

The jackscrews of the space frame structure are used for fixing, and it is usually drilled and tapped on the side wall of the sleeve. Then you can insert the shaft into the inner hole, and tighten the screw hole to achieve the tightening effect. Most of them are shaft holes, and jackscrews are used to hold the shaft to prevent it from moving back and forth. Most of the fasteners used between the shaft and the sleeve to prevent the shaft and sleeve from changing the position of the shaft during use.   The jackscrew hole, as the name implies, is a screw hole for jacking up. It is convenient to disassemble when parts need to be disassembled during equipment overhaul or other situations. Screw the jackscrews into the hole to separate the two assembled parts in order to achieve the purpose of disassembly. Product designers should fully consider the disassembly and assembly of parts. Jackscrews can be used to prevent relative movement between the shaft and the sleeve. There are als...

  The economic performance of steel structure space frame has attracted more attention. How to control the project cost and give full play to the comprehensive technical and economic advantages of the steel structure space frame, the engineering design stage is the key stage. In the preliminary design stage, the possibility of affecting the project cost is 75%-95%; in the technical design stage, the possibility of affecting the project cost is 35%-75%; in the construction drawing design stage, the possibility of affecting the project cost is 5%-35 %. Therefore, the quality of the design and whether the design is optimized will have a direct impact on the project cost. There is more room for the selection of materials in the design stage of the steel structure grid. The choice of materials is different, the direct cost of the project is different, and the total cost is different. Reasonable selection of engineering materials and control of the unit price of materials or engineering...

  First of all, we need to know what is the ‘ Portal steel structure ’, it’s a flat structure made of steel , which is composed of variable cross-section columns and variable cross-section sloped beams. It ’ s widely used in the steel structure of single-storey industrial and civil houses, such as single span, double span or multi span single and double slope portal steel structure.   Its optimization method is similar to the steel structure space frame , the optimization scheme of portal steel structure also adopt the asymptotic full stress method, that is, the section size of portal steel structure members is selected and modifies through multiple calculations and analysis to make it reach or close to the full stress stats as far as possible until the section size of all members of portal steel structure does not need to be modified, so as to minimize the amount of steel and achieve the lowest cost of optimization goal. The modification of component section size is also the ...

  What methods are used to reinforce steel structures? Let me tell you: 1. Enlarge the reinforcement of the component section When using enlarged section to strengthen steel members, the selected section form should be conducive to the reinforcement technical requirements and consider the existing defects and damage. The reinforcement of steel structure engineering needs to be based on actual conditions. In many cases, different parts have different requirements for the quality of reinforcement. Therefore, steel structure engineering should choose appropriate reinforcement methods and conduct reinforcement at different parts. 2. Connection reinforcement and the connection of the reinforcing member The connection method of steel structure includes welding seam, rivet, ordinary bolt and high-strength bolt connection method, which should be determined according to the reason, purpose, force condition, structure and construction conditions of the structure that needs to be reinforced,...

The painting of bolt ball space frame steel pipe  has the function of anti-corrosion. Because the surface of steel bar will be covered with oxide skin, welding slag, dust and oil stain during processing, transportation and storage. So workers need to treat the surface of steel bar before painting to remove the rust,burrs and other substances on the surface, otherwise, it will affect the adhesion and corrosion resistance between the coating and the pipes,and it will also cause the steel bar to continue to corrode under the protection of the coating, make the coating peel off, affecting the mechanical properties and service life of pipes.        The following is the surface treatment method of space frame pipe before painting： 1.  Manual processing There are mainly scrapers, wire brushes or grinding wheels etc. The rust and scale on the surface of steel bar can be removed manually, but the manual treatment has high labor intensity, low production effici...

Chemical plant steel structure paint requires corrosion resistance such as water resistance, moisture resistance, heat resistance, hot steam, and alkali resistance. Chemical plant steel space frame structure paint types include: alkyd, epoxy, polyurethane, acrylic, acrylic polyurethane, silicone resin and fluorocarbon resin. Chemical plant steel structure paint painting requirements: 1.  Sandblasting and rust removal of steel structure parts that have been cut to Sa2.5 level. 2.  The prefabricated parts after sandblasting shall be painted with epoxy iron red primer within 4 hours, with a thickness of ≥40µm. 3.  The pre-welded parts of the prefabricated parts (both sides of the weld bead during welding) are pre-coated with weldable inorganic zinc-rich paint with a thickness of ≥25µm. 4.  After the primer surface of the steel structure prefabricated parts is dry, apply the epoxy mica middle layer paint with a thickness of ≥60µm. The following is a matching scheme for...

For the space frame steel structure processing has strict requirements on the static and dynamic properties of steel, such as elasticity, plasticity, strength, toughness, and scrap mechanical properties. The mechanical properties of steel are the main basis for structural design. Secondly, introduce the damage form of steel and the main factors affecting the performance of steel, as well as the classification, selection principles and specifications of steel. To understand the characteristics of steel structures in depth, it is necessary to start with the material of the frame steel structure and master the working performance of the steel under various stress states, different production processes and different use conditions, so as to be able to select the appropriate steel, not only to make the structure safe and reliable, and to meet the requirements of use, it is possible to save steel and reduce the cost. There are many steel requirements   in steel structure engineering, ma...
