Q:How can a round steel weld on a flat steel plate be flat and qualified?
If it is full weld, for strong, don't groove. There must be no problem with the welding. If you hit the groove, it will deform. When welding, you should do spot welding and diagonal welding. I think you should be able to understand this, but I don't know what you are using for it,
Q:Why is it better to use round steel than flat steel in lightning protection?
In the construction of lightning protection, both round bar and flat steel have different uses. Flat steel is generally suitable for horizontal connection between vertical grounding poles for lightning protection. Round steel is suitable for lightning protectionThe guiding line and connected with lightning. The roof, all of the junctions are connected by welding requirements do not exist, what striking issues... The technical norms of the state said so, does not have what good and bad problem
Q:Is the shear wall concealed column stirrup steel or round steel?
Now the shear walls, columns and stirrups are basically round steel bars, and their requirements are as follows: 6.5~12 mm in diameter steel bars, most of the reel into a disk; 12~40 mm in diameter, usually 6~12 meters long straight bar. I grade steel (Q235 steel) are rolling for smooth circular section, supply form of material, diameter of not more than 12mm, the length is 6m~12m.
Q:How do you know the diameter and weight of a round bar?
Round is a round, the quality of its G (in grams) is equal to the volume multiplied by the density of 7.85 steel, and its volume is equal to the bottom area multiplied by the degree of L (in cm), then the bar diameter of d=4 * G / L / 7.85 / 3.14 value points
Q:Is HRB335 round steel or rib steel?
H, R, and B are the first letters in English for hot-rolled (Hotrolled), ribbed (Ribbed) and reinforced (Bars) three words.The numbers behind HRB represent the mechanical properties of the material they produce. The specific value is the yield strength of the material, sigma S (or Sigma P0.2). HRB335, indicating rebar with a yield strength of 335MPa.
Q:Weight algorithm of round steel
1, the appearance is different, round steel appearance of round, no grain without ribs, other steel surface appearance has carved or ribbed, this causes the round bar and concrete bonding force is small, and other steel and concrete bonding force.2 ingredients are different, round steel (grade a steel) belongs to ordinary low carbon steel, and other steel bars are mostly alloy steel. 3 strength, steel and other steel with high strength low strength, namely, diameter of the same size as compared with other steel, round steel can bear the pulling force than other reinforced small, but the plastic steel reinforced bar is stronger than the other, there is a large deformation in the break before, and it reinforced the deformation the break before the much smaller.
Q:Difference between cold drawn round steel and round steel
There are different reasons for the residual stress in hot rolled and cold-rolled steel sections, so the distribution of the residual stresses is also quite different. The residual cold-formed steel section stress distribution is curved, and hot rolled steel or steel welding section on the residual stress distribution is thin.
Q:What kind of nuts do you need for round 20 rounds?
The M22 thread can be made, if made M20, need a car off some. You may be talking about support, depending on how big your lead screw is.Stainless steel round bar refers to the solid steel strip with round section. The specifications are expressed in millimeters of diameter, such as "50", which means a stainless steel round bar of 50 millimeters in diameter.
Q:Why is the round bar bent?
In fact, the stress and deformation complex around reinforced concrete, bond stress varies with grip length of the rebar so bond strength with steel type, shape and position of the embedded in concrete, different direction and change, is also related to concrete strength, concrete compressive strength the higher the strength, the bond strength is generally determined by R=P/3.14dL. P for pullout force, D, rebar diameter, L, steel embedment length.
Q:How to distinguish a round bar from forging? Cold drawing? Hot rolling?
Hot rolled round steel, used in construction and general hardware parts processing is very common. Cold drawn round steel (do not know is not cold dial round bar). But I understand by the cold dial round bar Also mainly used in hardware parts processing and production. Such as hinge shaft core or other surface and diameter requirements of production and processing occasions.
