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:Is round bar steel?
In actual engineering, it is not necessary to use steel bar instead of round steel, but it should not be reversed. In addition, the diameter of the round steel bar is generally not large, but the diameter of the round bar is very large.
Q:40CrMo what is the round steel material?
High strength, high hardenability, good toughness, little deformation during quenching and high creep strength and lasting strength at high temperature.
Q:Why can't the grounding device be replaced by steel bar instead of round steel?
When using the steel structure as the ground, and hidden in concrete ground, in addition to the local connection is not what you said most of the other for round steel, screw steel, is the existence of these 1 steel, is more curved surfaces, easy to discharge. 2, the thread steel belongs to high carbon steel, conductivity is inferior to round steel." The problem? Then the building, simply all alone round or flat! Don't get it, do more beneficial and carp, social progress! Therefore, it is a mistake to use the steel bar instead of round steel to join the bar
Q:What's the difference between round steel and other steel bars?
Different appearance, round steel appearance garden, no grain without rib, other steel surface has carved or ribbed. This causes the round bar and concrete bonding force is small, and other steel and concrete bonding force
Q:What kind of steel bars are used in general civil buildings?
Steel is the HRB335, the diameter of 12 to 22, 25, 28, even 32, and then rough generally appear in the mass concrete construction, not commonly used, generally below 25 is commonly used in masonry structure in rural low level below 16 is most commonly used. Used as beams, columns, main bars and stand bars, etc.
Q:How is the copper wire and galvanized round steel connected during the construction of the lightning protection device?
Grounding device is an important component of lightning protection device. The earthing device releases the lightning current to the earth, and limits the lightning protection device to the ground voltage not too high. In addition to the independent lightning rod, the grounding device can be shared with other grounding devices on the premise that the grounding resistance meets the requirements.
Q:How can stainless steel rounds occur? Is it a quality problem?
Cracks caused by surface folding, cracks and steel surface of 15 degrees to 75 degrees angle, about 1.5 ~ 3.5mm, tail vortex shape, slightly decarburization on both sides, decarburization layer 0.15 ~ 0.25mm, crack in the presence of oxide scales. Its macro shape is in the surface of the round steel along the rolling direction into a straight line or zigzag, continuous or intermittent appear in the partial or full length of steel. This shows that this is a folding process in the process of rolling steel. Main reasons of folding is finished before the workpiece with a handleonapot; secondly, in the process of rolling each pass from the handle, flash, serious scratch, damage, and roll ring groove wear etc., can make the product surface folding; in addition, such as the serious defect of blank, if cleaning may also be caused by improper finished folding. Therefore, the main measures to reduce or avoid folding appear: pass through reasonable design, accurate estimation of the spread, precisely adjust the position of roller groove, reduce or eliminate the finished product before rolling the handle, flash, scratches and other defects; the serious defects of the blank surface carefully cleaned.
Q:What is galvanized round bar?
A cylindrical bar of iron or steel bar that crosses a layer of zinc on its surface.
