Q:Why is the earthing device forbidden to use thread steel instead of round steel as lap steel bar?
H, R, and B are the first letters in English for hot-rolled (Hotrolled), ribbed (Ribbed) and reinforced (Bars) three words. Hot rolled ribbed bar is divided into two levels, HRB335 (old No. 20MnSi), three HRB400 (20MnSiV, 20MnSiNb, old No. 20Mnti), four grade HRB500 three grade.
Q:Why the longitudinal tie bar adopts screw steel bar, and the transverse transmission bar adopts light round steel bar.
Dowel arm for transverse construction joint. The transverse construction dowel bar is applied with a light circle and half coated with asphalt, allowing sliding. In practical application, the construction units are convenient for drawing, often use thread steel, and do not apply asphalt. The concrete pouring time on both sides of the construction joint is different, the contraction during the condensation process is not synchronous, and the dowel bar can not be stretched and formed a weak link. Cracks occur at this weak point when concrete slabs contract under loads or natural factors.
Q:What is the sign of steel rebar
Standards are the uniform rules for repeating things and concepts. It is based on the comprehensive achievements of science, technology and practical experience, and is approved by the competent authority and issued in a specific form by consensus by the parties concerned, as a criterion and basis for common compliance.
Q:How much is the minus difference per ton of thread steel?
H, R, and B are the first letters in English for hot-rolled (Hotrolled), ribbed (Ribbed) and reinforced (Bars) three words. Hot rolled ribbed bar is divided into HRB335 (old No. 20MnSi), HRB400 (20MnSiV, 20MnSiNb, veteran, 20Mnti), HRB500 three brands.
Q:What does thread steel have to do with scrap steel?
There is a need to go through the processing of the construction units in the construction process of steel, for example, generally buy spiral steel to the standard 9 meters or 12 meters, the Jianshi needs 2.5 meters long 3.5 meters long and 1.7 meters long, 9 meters long steel eventually left a little cut small head these small head, or sold to a blacksmith shop, or you can only do what he can do, if he can do to the recycling of steel scrap processing.
Q:What is the difference between three - grade steel and other grades?
1, different grades of steel (chemical composition is different). HRB335 grade steel is 20MnSi (20 manganese silicon); HRB400 grade steel bars are 20MnSiV or 20MnSiNb or 20MnTi etc.;2, strength is different, HRB335 grade steel tensile and compressive design strength is 300MPa, HRB400 grade steel tensile and compressive design strength is 360MPa.
Q:Now, the two project is to use rebar or rebar?
Of course, depends on what steel is used for components, such as the two structure of the structure column, and other minor parts, it does not matter.
Q:What is thread steel for?
1. nominal diameter range and recommended diameterThe nominal diameter of the thread steel is from 6 to 25mm, and the nominal diameter of the standard steel is 6, 8, 10, 12, 14, 16, 20, 25,, 32, 40 and 50mm.Allowable deviation of surface shape and dimension of 2. ribbed steel discThe ribbed steel bars with ribbed threads shall meet the following basic requirements:The angle between the transverse ribs and the axis of the steel disc should not be less than 45 degrees. When the angle is not greater than 70 degrees, the direction of the cross section of the thread steel is opposite to that of the upper rib on both sides;The transverse rib and the spacing l shall not be greater than 0.7 times the nominal diameter of the steel;The angle between the sides of the transverse rib and the surface of the threaded steel shall not be less than 45 degrees;The sum of the gap (including the width of longitudinal ribs) between the ends of the cross bar and the end of the cross bar of the threaded steel shall not be greater than 20% of the nominal circumference of the thread steel;When the rebar nominal diameter less than 12mm, the relative rib area should not be less than 0.055; the nominal diameter of 14mm and 16mm, the relative rib area should not be less than 0.060; the nominal diameter is more than 16mm, the relative rib area should not be less than 0.065.
Q:The difference between round face and round bar steel on concrete
1., the thread of steel thread, round steel is not, is flat2. commonly used round steel materials are generally Q235 and HPB300, thread steel is HRB400, yield strength is not the same3. generally, thread steel is more expensive than round steel
Q:Are rebar bars = rebar?
Generally speaking (not absolute circle) steel is usually made of plate steel as the main form of packing, while threads are usually packed in straight strips.Turn left and turn right |
