Through planning and implementation, the short materials produced in the blanking process of the project can be connected and extended.
41cm-50cm steel bars are uniformly made into 40cm steel bars, which are used as cross bars of double f cards.
This helps to keep the length of reinforcement consistent and reduce the cutting of reinforcement due to uneven joints, resulting in short ends.
More than 1m is used as stirrup cross bar, and less than 50cm is used as stirrup support.
Those that cannot be used less than 300mm are put into the waste pool for treatment.
It is better to be long than short and discard at will.
Reasonably set reinforcement joints and make full use of short reinforcement heads: 1) reasonably arrange reinforcement joints of frame beams and frame columns to reduce the generation of short reinforcement heads.
Secondary utilization of waste reinforcement: 1) after the waste leftover materials are hoisted back to the processing yard, they are classified and sorted and reused, or they are changed to draw hooks or processed into stirrups.
Building communication media ID: jianzhong001 at present, the reinforcement engineering generally has the situation that adverse control leads to serious loss.
How to reduce the loss of reinforcement has become an important aspect to test the management level of the construction site.
According to 18g901-1, joints can be set in the side 1 / 4 section of the clear span of the frame beam.
Let’s take the project of the second company of China Construction Eighth Engineering Bureau as an example to see how to reuse the reinforcement waste and short materials on the construction site? Formulate the management and control measures for short materials of the project: according to the drawings and characteristics of the project and in combination with the actual situation, require the subcontractor to strictly implement the use of short materials, formulate the management and control measures for short materials of the project, and give warning and fine to the subcontractor if it is found that it does not meet the requirements.
2) In the actual field construction process, the waste stirrup can be changed into hook and other secondary utilization due to the error of stirrup proofing or the change of drawing.
4) The surplus materials are mechanically connected into pipe piles and used as pile core reinforcement.
2) Make full use of the background reinforcement processing to cut off the short end of the reinforcement.
The phenomenon of using only whole materials on site and using short materials as waste materials occurs frequently, resulting in excessive loss of reinforcement.
Weld in pairs.
According to the actual needs, 5cm-50cm reinforcement is used as double f card.
The short head of reinforcement with a length of about 50cm-70cm is used to make ground anchor.
3) 80cm to 110cm reinforcement is used as column reinforcement positioning hoop.

Set up short materials classification and stacking signboards on site to clarify the main application scope of all kinds of short materials: stirrup bar made of reinforcement material head: reuse after straightening the material head: reuse after welding the material head: according to the connection specification, the mechanical connection joint of reinforcement can be at any position to reduce the restriction on the connection position of the joint (especially the secondary parts such as the second row of reinforcement), So as to reduce the waste of reinforcement due to the limitation of joint position.
< > 5) Can be Φ 16 one Φ 20.
4) The wall thickness of the project is mostly 40cm.
The short head of 5cm < x < 50cm can be cut into "f end" of double f cards.
3) It can be used as measure reinforcement, such as positioning reinforcement and fixing wire box reinforcement.
6) Less than Φ 16, which can be fully utilized in the secondary structure.

Then weld it into a double f card< Span = "" > < / x < 50cm short head can be cut into "f end" of double f card.
The height of the stirrup densified area of the frame column is consistent with the height of the first joint above the floor, and joints shall not be set in the densified area.
Used on structural columns, ring beams, etc.
