Q:Are steel bars used more in high-rise buildings or steel?
The shear wall structure is used in many round bars, such as vertical wall bars, horizontal bars, steel bars and stirrups. Note that only general structures are concerned.
Q:What specifications should be used for the three - step steel electroslag pressure welding electrode?
The electrode (coveredelectrode), is the metal coating in the welding core (coating), uniform centripetal pressure applied to core. The core metal cored electrode, in order to ensure the quality and performance of the weld, there are strict rules on the contents of metal elements in the core, especially for harmful impurities (such as sulfur, phosphorus content, etc.) should be strictly restricted, better than the base metal. The electrode consists of two cores and coating composition. The different cores are also different. The core components directly affect the composition and properties of the weld metal, so the harmful elements in the welding core to as little as possible.
Q:What's the difference between finish rolling thread steel and ordinary thread steel?
To say the difference between the new bridge finish rolling thread steel and ordinary thread steel main difference between finish rolling thread steel: mainly used for high strength, difference is mainly different strength, chemical composition is not the same:Finish rolling thread steel is prestressed steel, and its strength is higher than ordinary thread steel.
Q:Two grade steel and three grade steel difference, the construction of the use of thread steel in general how to use the level?
According to the difference of prestressing strength, the trend is that the strength is higher and higher. The quantity of grade two steel has been replaced by grade three steel, and this year there are many 400E resistant steel
Q:25 screw steel, how many meters per meter?
25 thread steel one meter 3.86kg.Method of calculation: 0.00617 times the square of the diameter of the steel bar. The weight of each diameter of the steel bar (kg) can be calculated.Steel is known as hot rolled ribbed bar.
Q:What is the diameter of the cross section of the threaded steel?
Upstairs method is also OK: use a rope around the thread steel for a week, and then take out the length of the string, that is, thread steel perimeter L, and then according to the perimeter formula, you can find the diameter of D=L/ Pi Pi =3.1415926.The most accurate way is to use a vernier caliper or a micrometer.
Q:Why is thread steel thinner than crude?
Because the surface has a thread shape, it can increase the firm bond with the concrete. The longitudinal reinforcement and stirrups shall be used preferentially in the concrete members. Because the rebar is low alloy steel and its price is higher than that of low carbon round steel, the construction unit or design unit usually starts from the practical angle of the general civil building
Q:Does the grade three thread steel with "E" have the same information price as the ordinary three grade thread steel? Is there a big difference?
As far as I know, the price of information may not be divided into "E" and "E", but there are mandatory requirements on the standard. It is estimated that the price will not be much different.
Q:What's the difference between rebar and thread steel?
Different strength. The design strength of round steel (HPB235) is 210MPa; the strength of thread steel is higher than that of round bar; the design strength of HRB335 is 300MPa; the design strength of HRB400 is 360MPa.
Q:What is the difference between the actual weight and the actual weight of the steel thread?
The actual weight is weighed and weight is calculated according to the theory of diameter *0.00617*M* diameter * * the number of root number general weight were weighed weight greater than you look at this with the giant is even large or small factory of some difference.
