Q:What does "HJ-1" mean in steel structures?
In steel structure, HJ-1 is truss number 1.
Q:How to distinguish between steel structure materials and structures, steel types and specifications?
Low alloy steels refer to steels whose total amount is less than 5% by adding one or more small amount of alloying elements during steelmaking. Low alloy steels have higher strength because they contain alloy elements. According to the current national standard "low alloy high strength structural steel" (GBT/l591) provisions, its brand and carbon structural steel grades of the same method, the commonly used low-alloy steel has Q345, Q390, Q420 and so on.The delivery of low alloy steel when the supplier should provide quality assurance of yield strength, ultimate strength, elongation and bending test of mechanical properties; to provide the content of chemical components of carbon, manganese, silicon, sulfur, phosphorus, vanadium, aluminum and iron quality.The quality grade of low alloy steel and carbon steel the same except A, B, C, D four grades, increased E level, which requires 40 DEG C when Charpy V notch power is not less than 27J (vertical). The requirements for the content of carbon, sulfur, phosphorus and aluminum in different quality grades are also different. The deoxidation method of low alloy steel is killed steel or special killed steel. Q345-B is a B grade killed steel with a yield strength of 345N / mm2; Q390 - D represents a D - grade special killed steel with a yield strength of 390N / mm2.
Q:Is cast-in-place concrete attic good or steel structure + ALC board good?!
The short cycle of cast-in-place steel structure high stability, light weight, does not destroy the original structure, anchorage hole cast-in-place the original wall hit double row hole spacing of ten cm each with adhesive implantation wall, wall depth of ten to fifteen cm, and the steel structure is not greater than the chemical anchor spacing bolt with wall of not less than thirty cm fifty cm fifteen cm deep into the root.
Q:In the steel structure of steel purlin 160*60*20*2.5 is what mean
Steel structure is mainly made of steel material, and it is one of the main types of building structure. The structure is mainly composed of steel beams and steel plates, such as steel beams, steel columns, steel trusses and so on. Each component or component is usually connected with welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise and other fields.
Q:What is steel structure steel plate?
The penetration welding spot welding, welding should be prepared before the arc welding test pieces, adjust the welding current. Because the floor plate at the bottom of horizontal and vertical supporting formwork, pouring concrete material should not be too concentrated, the plate vibrator timely allocation of vibration.
Q:Who are the customers of color steel and steel structure?
Steel structure is mainly used in all types of production plants, customers mainly entrepreneurs, investment companies, all types of production enterprises, covering all sectors.
Q: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).
Q:What is the budget for steel structure?
It may seem a little complicated, but it's not difficult to analyze it carefully. After you calculate the area, multiply the thickness by the theoretical weight, then divide by 1000 to get the result that the unit is ton.
Q:Tall steel columns with studs what effect is there?
Methods: through stud welding welding robot power, column set in stud welding gun, anti arc seat, starting gun, current fuse, ring is generated by arc, short columnar stud with a certain speed the top tight end of base metal melting, cut off the power supply of columnar stud welding fixed to the base metal. This method is also called stud welding.
Q:Where is the steel structure? High strength bolts?
Steel structure is generally beam column connection, beam and beam connection with high-strength bolts, if the high-rise steel structure building support system should also use high strength bolts
