Step by step, it should be tightly used at the bottom of the beam. The spacing depends on the size of the square material. The normal spacing is 5mm-8mm. If the thickness of the square material is less than 4mm, the spacing should not be greater than 45mm. The specific calculation method of step-by-step tightening: 4cm constructional column+template 5cm (2.5cm on both sides)+square timber 2cm (1cm on both sides) = 65cm recommended model 8cm and so on.
the spacing of the opposite screw depends on the height of the component, which is generally about 35mm, and the thickness of the square material should not be less than 5 mm. The spacing between the water stop screw and the opposite screw of shear wall is similar, generally around 35mm, and the square material thickness shall not be less than 5 mm..

The following problems should be paid attention to when using it step by step:
1. One end of the movable chuck must be used with wood, not with hard materials (such as steel pipes) to prevent the fixture from being clamped.
2. Due to the limitation of materials, the "step by step" formwork should be reinforced by the formwork with the maximum effective use range of fixture less than 8㎝.
3. After the fixture of the "Step by Step Tightening" template is set up, it is forbidden to trample on the fixture to prevent safety accidents caused by the looseness of the fixture or die expansion caused by the looseness of the fixture.
4. "Step by step" storage should be done when using. Because of its small size and light weight, the clip is very easy to be lost if it is not properly kept. The movable chuck part is easy to be lost. After the hook-shaped clamping rod is inserted into the movable chuck, the tail of the hook-shaped clamping rod should be built into a small drum by surfacing welding with covered electrode, or a hole of 4㎜ should be pierced and bolts should be screwed, so that the movable chuck will not be lost.
5. After the fixture is dismantled, it should be piled up in a designated place, and pay attention to moisture-proof treatment to prevent corrosion.
