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:How to make the round welds on flat steel flat and qualified?
It is required that the current is suitable and the bar is stable. If required, the groove can be turned on the round steel to ensure that the welding is beautiful and qualified
Q:How many meters is the minimum loading surface of galvanized steel wire for grounding grid?
Flat steel adopts negative deviation rolling, but according to actual weight delivery, the utilization ratio of steel plate increased by -5 percentage points. Flat can according to user needs, set the thickness, width and length of production, for the user to reduce the cut and save processes, reducing labor, material consumption, but also reduce the loss of raw materials processing, time saving, material saving. Products have been specialized in steel structure manufacturing, machinery manufacturing, automotive industry, mining machinery, lifting machinery and other industrial materials.
Q:Are more bars used in high-rise buildings?
Look at the architectural design requirements and seismic grade, light steel reinforcement is mainly stirrups, columns, beams, shear walls generally use thread steel, plate bars and distribution bars are generally cold and twisted steel bars
Q:Which steel wire is the same diameter as round steel more resistant to breaking?
A wire rope is a flexible rope twisted with a plurality of strands or strands of fine steel wire. The wire rope is twisted by multi-layer steel wires and then twisted by a certain number of strands into a spiral rope at the center of the rope core. In material handling machinery, for lifting, traction, tensioning and loading purposes. The wire rope has the advantages of high strength, light weight, stable work, easy breaking and whole breaking, and reliable work.
Q:On the market, 8mm Round Bar is not 9 meters a root? How much does it weigh about 300 meters? How much does it cost?
8 there is no regular reinforced steel bars are straight, round, there is straight, as you said 9 M 1, but that's rolling, if their home, can also, engineering is prohibited
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:The problem of dowel bars on concrete pavements?
The dowel bar is arranged according to the transverse contraction joint and expansion joint set, meaning that a transverse contraction joint and expansion joint place dowels, are not plate must be set. In general, each 200m set a expansion joint, or other road intersection, and bridge connecting point must be set up.
Q:Excuse me and steel disc round what is the difference?
Wire rod refers to the hot-rolled steel bar of 5-22mm diameter or the special-shaped steel of this section. As a result of wire rod delivery, it is also known as wire rod.
Q:Which is stronger, steel pipe or round steel? Which is good at bending?
Round bars are, of course, more powerful, but not much higher.
