What are the functions of 8 kinds of important reinforcing bars in the classification of reinforcing bars?


Reinforcing steel is one of the materials that can be seen everywhere on construction sites. It is equivalent to the skeleton of our human body, and reinforcing steel is also divided into many kinds. Different reinforcing steels have different roles. So today, Xiao Bian wants to share with you the classification of steel reinforcements. The role of 8 kinds of important reinforcing bars is introduced.

What are the classification of rebar

1. Long ribs

By means of a long rib, it is possible to use a lap-type connection in the case where the diameter is not the same in the specified section, so as to ensure that the reinforcement of the beam portion can exert tensile strength.

2. Through ribs

Crossed ribs are steel bars that can penetrate through the length of the entire component. They neither bend nor break in the middle. When the reinforcement is too long, it can be welded. The splicing ribs belong to both the stressed steel and the erected steel bars.

3. Stand up ribs

In the concrete structure, the erection ribs serve to fix the position of the stirrups. When a negative moment reinforcement is present above the beam's support, the erection ribs can be arranged only on the mid-span part of the beam. Welded or welded with negative moment steel reinforcements, and at the same time as overlapping, we must also meet the requirements of the overlap length for banding. Strut ribs also belong to a continuous material, and it is required that the ribs on both sides of the upper part of the beam must penetrate each other. At this time, the truss can bear a part of the negative bending moment at the support.

4. Structural ribs

Constructing ribs in the steel bar classification can meet the requirements of the structure. For various reasons that are not easy to calculate and do not take into account, the steel bars that are set can be constructed with structural steel bars. For example, the steel bars used in concrete structures can be erected and longitudinally constructed. They are all located in the middle of the beam side and can also be called waistbands.

5. Distribution bars

The distribution ribs appear in the plate and are perpendicular to the stressed steel bar. The effect of this kind of steel bar is to fix the position of the stressed steel bar and at the same time distribute the load on the plate to each stressed steel bar, and at the same time prevent the contraction of the concrete. The reason for the temperature change is that cracks appear in the direction of the stressed steel bars.

6. Negative tendons

In reinforcement classification , negative reinforcement is used to withstand negative bending moments. Usually, the reinforcement is used when the beam is near the upper position of the support or the upper part of the plate is close to the support.

7. Curved ribs

Curved ribs are generally used in the upper part of the beam at the support, can withstand negative bending moments, and are located below the beam in the middle to support the positive bending moment of the beam.

8. stirrups

The stirrups are used to meet the shear strength of the inclined section, and at the same time, they are connected with the reinforced tendons of the stressed main tendons and the pressed areas, divided into single limb stirrups, closed rectangular stirrups, open rectangular stirrups, polygonal stirrups, and diamonds. Stirrups, round stirrups, and well-shaped stirrups.

Xiao Bian summary: The above is the role of reinforcing steel classification and 8 kinds of important reinforcing steel that Xiao Bian shared for everyone. I suggest you go to the regular building materials manufacturers to purchase reinforcing steel materials. Hope that the above sharing can help you, if necessary For more relevant information, please continue to pay attention to the website of this website.
