Q:What are the different uses of wire rod and thread steel?
According to statistics, China's construction industry accounts for about 50% of the total steel consumption. As one of the resources consuming industries, the construction industry must adjust the consumption structure of construction materials, energetically apply high-strength steel bars and high-performance coagulation, and take the road of economical development. If the current use of steel and concrete to raise an intensity level, it can bring enormous savings to society. For example, by calculation, according to the standard requirements, if the reinforced concrete leading force steel strength increased to 400-500N/mm2, then can be in the current level of steel consumption to save about 10%.
Q:Is the tie bar used for the longitudinal joint of cement concrete pavement threaded or smooth? Where is the dowel bar for the transverse joint construction?
Dowel arm for transverse construction joint. The transverse construction dowel bar is applied with a light circle and half coated with asphalt, allowing sliding. In practical application, the construction units are convenient for drawing, often use thread steel, and do not apply asphalt. The concrete pouring time on both sides of the construction joint is different, the contraction during the condensation process is not synchronous, and the dowel bar can not be stretched and formed a weak link. Cracks occur at this weak point when concrete slabs contract under loads or natural factors.
Q:What does "4E" mean on the rebar?
The meaning of 4E on the rebar is HRB400 seismic reinforcement (HRB400e). 4 is HRB400 (formerly known as grade 3 steel), e is earthquake's e, meaning earthquake resistance. The steel bars marked with e have reached the standard of "anti-seismic" steel issued by the state.
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 to calculate the theoretical elongation of finishing thread steel?
The theoretical elongation of fine thread steel is calculated by L=P.L/ (E.A), P is force, L steel bar is longer, E is elastic, and A is area.
Q:What are the main use of threaded steel?
The rebar is a kind of small section steel, mainly used for the skeleton of reinforced concrete construction members.
Q:Why is the difference between left and right threads? What's the difference?
There are some poles on the diagonal cable, the blue bolt on the left thread is also used more, one is left-handed, one is right-handed rotation, the middle nut can adjust the tension of the cable.
Q:How much is the difference between the three grade thread steel and the two grade thread steel?
For some time, due to the supply of three threads, and the two level of demand, resulting in two, more expensive than three.
Q:What are the main uses of threaded steel?
The main use of rebar is to use beams and columns of important structures as well as bridges. The upper rib is stronger than the round steel when combined with concrete pouring!
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.
