The High Precision Stirrup Bending Machine Manufacturer introduces you to some knowledge about the steel bar. The steel bar sample is mainly based on the drawings and related changes. It is calculated according to different components, different parts, different seismic levels, and different concrete strength levels. In line with the requirements of the relevant specifications, the steel bar flattening specifications such as 16G101 are often used at present. It is very important to turn over samples, but the calculation process of turning over samples is complicated and cumbersome. With the progress of society, software calculation has been gradually adopted on the spot, but for complex components, the software cannot meet it at present.
The sample-turning personnel must be familiar with the drawings and relevant specifications, and determine the mutual anchorage and avoidance relationship between beams and column reinforcement according to the specifications and drawings. Angle, length, stirrup size, etc., key parts, dense steel bars, intersections with section steel, etc., should be staked out if necessary.
The sample-turning work must consider operability, and must consider how to reduce the loss rate. Only operability can be implemented; only by reducing the loss rate can costs be controlled, so that efficiency can be increased.
Structural members on site include rafts, columns, walls, beams, slabs, stairs, etc. The raft is the support of the column wall, the column wall is the support of the frame beam, the frame beam is the support of the secondary beam, and the beam is the support of the slab. Among them, only columns, walls and frame beams are seismic components, and the rest are non-seismic components.
After receiving the rebar sample list, the processing team must read it carefully and understand the intention of the sample calculation for the combination of long and short materials before processing. The materials used must be qualified for retesting, and the use of materials without retesting or unqualified materials is prohibited.
Corroded and contaminated steel bars must be processed before processing, and can only be processed after being qualified. For small-diameter wire rod steel bars, straighteners are generally used for straightening; for wire rods, based on the steel bar grade, diameter, and cutting length provided by the steel bar ingredient table, the cutting machine is used to break the material, and then the graph of the table , Size for forming processing.
For steel bars requiring straight thread connection, in principle, a toothless saw should be used for cutting to ensure that the horseshoe shape and deflection do not appear on the cross section, so as to facilitate the qualified thread. After the material is broken, the rebar needs to be bent and formed according to the size and graphics in the material table, such as stirrups, hangers, wall horizontal ribs, hooks, and so on.
Bending is an important part of the processing process, and its processing quality directly affects the on-site lashing and acceptance. For example, stirrups, when several bending machines bend the same size at the same time, it is necessary to compare before mass production to ensure the size is uniform, otherwise the on-site lashing will be difficult, or directly affect the acceptance. You can use Steel Wire Bending Machine, Stirrup Bending Machine.
The processed materials are called semi-finished materials. Semi-finished materials must be listed, indicating the location of use, specifications, grade, quantity, etc., so that it is easy to find materials when tying.
The processed semi-finished steel bars are piled up in different parts, construction sections and categories. Rebars of the same part, the same component and the same type are put together. Before and after stacking, it is necessary to check whether the processing quality is qualified. Only qualified can be stacked.
Rebar processing is an important part of cost control. When cutting, the reasonable allocation of long and short materials is the key factor to reduce the loss rate.
