supply step-by-step railway clamp cement clip road clamp f-clamp 供应步步紧 铁路夹 水泥夹 公路夹 F夹

Supply is increasing rapidly: railway clamps, cement clamps, highway clamps, F clamps

Suitable for specific parts in engineering; suitable for models used in construction.
60 cm for the reinforcement of ring beams; ring beams below 30 cm
70 cm is suitable for brick-concrete and frame structures; 30–35 cm for structural columns
80 cm brick-concrete and frame structure; 40–45 cm structural columns
90 cm brick-concrete and frame structure; 50–55 cm columns
100cm brick-concrete and frame structure; 60–65cm columns
110 cm is suitable for frames in factories and high-rise buildings; 70 cm for columns
120 cm is suitable for the frames of factories and high-rise buildings; 75–80 cm for columns
The specific calculation method is as follows:
Example: 40 cm structural column + formwork 5 cm (2.5 cm on both sides) + 20 cm square timber (10 cm on both sides) = 65 cm. Recommended model: 80 cm, and so on.
(<t_40cm>Columns less than 40 cm in height can be reinforced without using square timber)
Explanation of the spacing between layers of structural columns
Column model, spacing distance
30–45 cm, 40 cm
50–55 cm, 1.5 or above, 30 cm
Less than 1.5, 40 cm
60–65 cm, 30 cm
Recommended usage method for columns over 65 cm in size
1. Clamp encryption method: For large columns over 65 cm, special attention should be paid to the reinforcement at the bottom (i.e., below 1.5 meters). Normally, the spacing below 1.5 cm is 30 cm. However, due to the size of the columns, the spacing should be changed to 15 cm. This layer that is used frequently is called encrypted layer. The encrypted layer can be removed 2 hours after the column is poured, and it can be used to reinforce other columns. This is known as the clamp encryption method.
2. Mixed utilization method: A method derived from workers' usage experience
(1) Utilized in combination with step buckles and butterfly clasps. (2) Utilized in combination with step buckles and triangular fasteners. (3) Utilized in combination with step buckles and steel pipes. (4) Utilized in combination with step buckle rods. Note: Although some fasteners have too many drawbacks and are facing obsolescence, combining them with step buckles makes the impact columns more practical.

Please note the following points when using it:
1. One end of the activity card head must be used in conjunction with wooden blocks; it shall not be used with harder materials (such as steel pipes) to prevent the clamping device from failing to hold tightly.
2. Due to the inherent limitations of the material, the “Step by Step Tight” template should be reinforced using clamps with a maximum effective range of less than 80㎝.
3. After the “Step by Step Tightening” template fixture is installed, do not step on it to prevent safety accidents caused by loosening of the fixture or mold expansion due to its looseness.
4. Proper storage measures should be taken during use. Due to their small size and light weight, clips can easily be lost if not stored properly. The movable clip head part is also prone to loss. After inserting the hook-shaped clip rod into the movable clip head, a small bulge should be formed at the end of the hook-shaped clip rod using welding rods, or a 4 mm hole should be made, followed by the installation of bolts, so that the movable clip head will not fall off the rod.
5. After removing the fixtures, they should be stacked at a designated location, with attention paid to moisture protection to prevent rusting.
