Butterfly buckle | Construction butterfly card | Butterfly buckle wholesale | Butterfly buckle manufacturer | Price

Butterfly card (butterfly buckle) is a new type of construction equipment, which is an ideal tool for locking and anchoring formwork tie rods. It uses the resistance generated when the wedge-shaped latch of the clamp clamps the tie rod to anchor the tie rod, and works reliably. Compared with traditional threaded tie rods, it not only replaces the functions of nuts and gaskets, but also changes the operation mode of traditional formwork tie rods, effectively controls the size of the formwork, improves the smoothness of the surface of concrete components, and applies flat buckles and butterfly buckles. , the tie rod does not need to be processed, saving thread processing costs. The tie rod material is widely optional. Steel rods and threaded steel bars can be used as long as they can pass through the clamp (general tie rods and the length of the tie rod is not restricted, as long as it is long enough. The construction operation is very convenient and fast. , saving nearly more labor than threaded tie rods, and can be used repeatedly, with long life and low maintenance costs!
Butterfly buckle (butterfly buckle is suitable for diameter steel pipes for purlins, and is an alternative to mountain-type cards.
Features Easy operation, quick loading and unloading, can reduce workers’ labor intensity and speed up the project progress by 50%. Sturdy and durable, can be used repeatedly without maintenance, reducing construction costs. Stable load, high safety.
Applicable range diameter circle Energy-saving use of steel and steel bars.

Description
Ensure the size of the concrete member The accuracy is based on the smoothness of the surface
Before wedge-tightening the pins, the template must be tightened with a special tool clamp (as shown on the right).
Based on the actual engineering, the structural engineer needs to calculate the total pressure and the number of uses. The principle is to ensure that the pressure endured by each unit does not exceed the safe load in the table above.
To prevent cement slurry and other debris from splashing when using a hammer to wedge the latch, a safety mask must be worn to protect your eyes during operation.
