Steel structure platform cost
- In general, such a floor, the amount of steel per square metre in about 50-80 kilograms, and now the cost is between 500-800 yuan.s
What is an engineering structure?
- According to the materials used, the main types of engineering structures are concrete structure, steel structure, masonry structure and wood structure, etc..s
Steel plate for steel structure, what kind of steel plate is it
- The grades of carbon structural steel are composed of four parts: the yield strength, the letter Q, the yield strength value, the quality grade mark (ABCD), and the deoxidation method notation (FZTZ).s
What is the proportion of paint for large steel structures and what thinners do they have?
- Fluorocarbon paint main paint for large steel structure paint: curing agent: diluent = (0.8-1.2): 0.1: (0.2-0.4) (weight ratio). Large steel structure paint regardless of variety or form, is composed of film-forming material, secondary film-forming material and auxiliary material into three basic substances: membrane membrane material: also known as binder, film-forming material for most compounds such as organic polymer resin (natural rosin, lacquer paint), tung oil, linseed oil, soybean oil (fish oil, etc.), such as synthetic resin mix after high temperature reaction, also paint inorganic composition (such as inorganic zinc rich paint).s
What does steel structure 8M24 mean?
- 8M24:8 (high strength) bolts or anchors are anchors at the bottom of the column, bolts in most other places, and M stands for the diameter.s
In the steel structure, should be the first high-strength bolts after the end of the welding, or first screw, then welding after the end of the screw?
- High strength bolt connection first start, from the middle to the periphery of the installation of high-strength bolts, all installed after, and then turn with torque wrench finally. The structure of high strength bolt joint needs little welding. Welding is definitely the last thing to do if needed.s
How is the steel structure foundation checked and accepted?
- The column position in the column surface measuring axis of projectile.Level of plinth elevation. Concrete plinth elevation 50 ~ 60 mm for general casting (compared with steel column base design, installation in elevation) with steel plate or early adoption by plasma plate leveling.When using the steel plate support plate, steel plate area should be determined according to the fastening force and compressive strength, concrete of foundation base plate two times before grouting at the bottom of the column load and anchor bolt. The contact between the shim and the base and the bottom of the column should be smooth and tight.When the cushion plate is used, the shrinkage free mortar shall be adopted. The strength of the mortar block should be higher than that of the base concrete before the lifting of the column, and the mortar pad should have enough area to meet the requirements of the load.s
What does "PD140*4" and "PL12*150" mean in the steel structure drawing?
- Homogeneous and isotropic material, an ideal elastic body, the most consistent with the basic assumption of the general engineering mechanics; material has good plasticity and toughness, and can have large deformation, can well withstand dynamic loads; short construction period; the high degree of industrialization, can carry out specialized production of high degree of mechanization; processing high precision, high efficiency, good sealing performance, so it can be used in the construction of tank, tank and transformer etc..s
