Step by step tightening is a new type of construction tool, mainly composed of two parts: hook shaped clamping rod and movable clamping head. Here is a detailed introduction to it:
1, Main uses and advantages
• Main use: Step by step tightening is mainly used for fixing templates during concrete pouring, which can replace traditional methods such as wire binding, rod screw method, and ring sealing method. It plays an irreplaceable role in the construction process.
Main advantages: Quick to use, not only can it save work time and improve work efficiency, but it can also save a lot of wood.
2, Model and Applicable Scenarios
• Common models: There are various specifications for the length of step-by-step tightening, including 70cm, 80cm, 90cm, 100cm, etc. The specific selection needs to be determined according to the specific parts and requirements in the project.
• Applicable scenarios:
60cm step by step tightening is suitable for reinforcing ring beams, especially those below 30cm.
The 70cm step by step tightness is suitable for construction columns of brick and concrete and frame sizes of 30-35cm.
The 80cm step by step tightness is suitable for construction columns of brick and concrete and frame sizes of 40-45cm.
The 90cm step by step tightness is suitable for brick and concrete and frame columns of 50-55cm.
The 100cm step by step tightness is suitable for columns with brick concrete and frame sizes of 60-65cm.
Longer step sizes, such as 110cm, 120cm, etc., are suitable for frame columns in factories and high-rise buildings.
3, Usage method
Hook one end of the hook shaped clamping rod that is tightened step by step onto one side of the template wooden square.
Use a small hammer to strike the lower part of the movable card head towards the hook end of the card rod until it is tightened. Due to the small gap between the hole of the activity card head and the card rod, it has self-locking function and can resist the expansion force generated by the template under stress.
4, Precautions
One end of the activity card head must be used in conjunction with wooden blocks and must not be used in conjunction with harder materials (such as steel pipes, etc.) to prevent the card from not being securely fastened.
The "step by step tightening" template should be reinforced with fixtures with a maximum effective range of less than 80cm.
After the installation of the "step by step tightening" template fixture, it is not allowed to step on the fixture to prevent safety accidents or mold expansion caused by loosening of the fixture.
When using, it is necessary to do a "step by step tight" storage work to prevent loss. After dismantling the fixtures, they should be stored in a designated location and treated with moisture-proof measures to prevent rusting.
In short, as a new type of construction tool, BBK plays an important role in the construction industry. Its advantages such as fast usage, time-saving, improved work efficiency, and wood saving make it highly favored.
