Q:Cast-in-place with 10 mm reinforcement, a good layer or 8 mm double layer? Why?
The plate near the gable should be equipped with double - layer reinforced wire mesh. Adding radial reinforcement at the corner of the wall. In the region where the temperature and shrinkage stress are greater, a double layer steel mesh should be installed.
Q:How heavy can a 25 mm thread steel bear?
Steel is known as hot rolled ribbed bar. Ordinary hot rolled steel bars are made up of HRB and the minimum yield point of the brand. H, R, and B are the first letters in English for hot-rolled (Hotrolled), ribbed (Ribbed) and reinforced (Bars) three words.
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: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:What is the difference between the II and III grades of threaded steel?
The difference between three grade steel and two grade steel can be divided into the following aspects: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.3, because of the chemical composition of steel and the ultimate strength of different, so in toughness, cold bending, fatigue and other properties are also different.
Q:How many kinds of steel are needed to build the building?
According to the processing methods can be divided into: hot rolled steel, heat treatment, cold drawn steel, steel cold drawn low carbon steel wire and steel wire tube; surface shape can be divided into smooth steel and thread; according to the varieties of steel can be divided into low carbon steel, medium carbon steel, high carbon steel and alloy steel etc.. The strength of China's steel bars can be divided into five grades: I, II, III, IV and V.
Q:Excuse me, the difference between round steel, screw steel, steel, plate material, steel wire, hope professional answer
The 2 plate and steel hot rolled steel plate, it is hard to know, the difference between rebar and rod easily screwed, clear, thread steel by chemical factory is a very deep rib.
Q:Are thread steels of coarse steel?
Thread steel does not belong to coarse steel, rough is shaped steel, fine is wire.
Q:What are the marking of the steel bars on the mills? Which factory is the 2LG16 thread?
In the steel mills logo is a symbol to a combination of numbers and letters, according to the strength of steel grade (with digital sign) + mills (referred to as letters marked) + bar diameter (with digital sign) according to the order of size at a certain spacing bar on one side of the uniform by Mark steel the strength grade of the number 2 (two steel), 3 (three steel), 4 (four steel) and other steel label; referred to in letters, such as LG (Lai Gang), JG (Ji Gang), KG (Kunming); diameter of steel bar by the number 12, 14, 16... 25, 28... Etc.. For example, the steel produced by Jigang has a diameter of 22 and the strength grade is 3 grade. The steel mark is 3JG22.
Q:Why the longitudinal tie bar adopts screw steel bar, and the transverse transmission bar adopts light round steel bar.
Steel is known as hot rolled ribbed bar. Ordinary hot rolled steel bars are made up of HRB and the minimum yield point of the brand. 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.
