Q:Why is thread steel thinner than crude?
Because the surface has a thread shape, it can increase the firm bond with the concrete. The longitudinal reinforcement and stirrups shall be used preferentially in the concrete members. Because the rebar is low alloy steel and its price is higher than that of low carbon round steel, the construction unit or design unit usually starts from the practical angle of the general civil building
Q:How to distinguish the quality of thread steel?
Quality materials are more standardized in terms of trademark and lettering. And inferior steel has no distinct brand mark.
Q:In the concrete floor, how big can the steel bar be replaced by the big screw steel? How to convert?
The strength of the reinforcement to be replaced must be greater than or equal to the original strength of the reinforcement. The tensile strength of the original reinforcement, the square of the diameter * the tensile design strength / the diameter of the reinforcement to be replaced by the square *, the tensile design strength.
Q:12 how much is one ton of thread steel?
Beijing market, hrb400e three thread 12 of the price of 2330 yuan / ton, that is, 2.33 yuan /kg; HRB500 four rebar 12 price of 2510 yuan / ton, that is, 2.51 yuan /kg
Q:What does it mean to have 22 4GJ on the threaded steel?
The brand of steel is expressed in terms of Arabia numerals or Arabia numerals plus English letters. HRB335, HRB400 and HRB500 are represented by 3, 4 and 5, respectively. HRBF335, HRBF400 and HRBF500 are represented by C3, C4 and C5 respectively. The name of the factory is expressed in Chinese phonetic prefix. Nominal diameter mm Arabia digital representation.
Q:What's the difference between earthquake resistant thread steel and common thread steel?
Seismic steel can meet all the performance indexes of ordinary steel, but also can satisfy the tensile strength and yield strength of the actually measured ratio of not less than 1.25 characters; yield strength and yield strength characteristics measured standard value of the ratio is not greater than 1.30; Taiyuan dedicated steel maximum force elongation of not less than 9%, the three criteria.
Q:How much is the weight of 6mm thread steel KG?
Multiple objects can be hung, not only to see the hook itself, the bearing strength is not enough, the hook is nothing, even with the bearing down together is possible.
Q:What's the difference between finish rolling thread steel and ordinary thread steel?
The rebar used in prestressed concrete is a kind of bar with big diameter, high strength and high dimension precision, which is rolled with an external thread on the whole reinforcing bar. The steel bar is screwed at any cross section with a connector with an internal thread to connect or screw on the threaded nut for anchoring.
Q:Why does the steel thread have longitudinal ribs?
The main function of the longitudinal ribs is the force to improve the performance of the transverse ribs, the stress of support surface transverse rib in the longitudinal direction, reducing flange stress concentration, so as to improve the mechanical strength of the reinforced rib, deformation of bond between concrete and steel reinforced concrete, the collaborative work and better.
Q:Can the thread steel of the steel platform of the fixed unloading platform not work?
The cantilever beam end should set the wire rope or steel rod with a layer of building structure of cable-stayed suspension type steel each node. The rings of wire rope and building structure Rachel should use HPB300 grade steel, its diameter should not be less than 22mm, the rings embedded anchor reinforcement anchorage length should be specified in accordance with current national standard "code for design of concrete structures" in GB50010.
