Q:Can I use steel bar instead of steel bar?
The substitution principle of steel bars is equal section substitution and equal strength substitution. Therefore, we can not use round steel instead of thread steel.
Q:Three - grade thread Phi 10 steel can replace a grade Phi 12 round bar? Which elder knows, trouble pointing.
Notes on reinforcement replacement1, steel replacement, to understand the design intent, the important components of the steel replacement, with the consent of the design unit (the actual: to change the design units should be agreed).2, steel replacement, should meet the minimum reinforcement ratio requirements and reinforcement structure (such as minimum steel reinforcement diameter, spacing, root number, anchorage length, etc.) provisions. The bar as possible with the original design of root number.3, crack resistance requirements of the components (such as crane beam, truss bottom chord, etc.) with smooth steel (not reinforced grade) instead of rebar.4, do not change the effective height of the component.
Q:Why is it better to use round steel than flat steel in lightning protection?
Of course, the contact area of flat steel and soil are large, relatively scattered large flow area, the construction is more convenient, in terms of price, we are willing to use flat, as for the problem of anti-corrosion, anti-corrosion paint, zinc can be taken, you know, the thickness of galvanized steel pipe is generally not flat, so true to see the term for the use of galvanized flat steel is not bad.
Q:What's the difference between round steel and carbon bound steel?
The composition is different, round steel (grade a steel) belongs to ordinary low carbon steel, carbon tie steel is mostly alloy steel.
Q:What kind of steel is used for anchor bolt material? What's the quality of anchor bolt material?
When the mechanical component is installed on the concrete foundation, one end of the bolt is J and L shaped, and is embedded into the concrete.
Q:What kind of nuts do you need for round 20 rounds?
The nut is connected to mechanical equipment parts, through the inside of the thread, the same specifications of nuts and bolts to connect together, such as M4-P0.7 and M4-P0.7 only bolt nut series connection (nut, M4 nut diameter is about 4mm, 0.7 fingers between the two thread distance of 0.7mm); US made products as well, such as screw nut only with the 1/4-20 1/4-20's collocation (1/4 refers to the nut inner diameter is about 0.25 inches, 20 inches each, 20 teeth).Self locking nut, lock nut, locking nut, four claw nut, the nut is screwed into the nut, screw rod nut insurance connecting nut cap nut six self-locking angle of anchor bolt with nut, six special angle crown thin nut eyenut.
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:Can the same grade steel instead of round bar be ok?
Physical and mechanical properties are different. Because of the different chemical composition and strength of reinforcing steel, they are different in physical and mechanical properties. The cold bending property of steel is good, can make the hook 180, screw steel can only make straight hook 90 degrees; steel weldability is good, with ordinary carbon steel electrode can be used to low alloy electrode; anti fatigue performance and toughness in steel bar is good.
Q:What is galvanized round bar?
Galvanized round bar generally refers to the wiring used for lightning protection in construction and installation. It is made of ordinary round steel (usually 8mm to 12mm diameter) and protected by electro galvanized protection layer. Galvanizing, differentiation, plating and electroplating, cold galvanizing and hot galvanizing etc..
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.
