    Butterfly card (butterfly buckle) is a new type of construction equipment, which is an ideal tool for locking and anchoring template pull rods. It utilizes the resistance generated by the wedge-shaped latch of the fixture to clamp the pull rod, anchoring the pull rod and ensuring reliable operation. Compared with traditional threaded tie rods, it not only replaces the functions of nuts and washers, but also changes the operation mode of traditional template tie rods, effectively controlling the size of the template and improving the flatness quality of the concrete component surface. The application of flat and butterfly buckles has the advantages of no need for processing the tie rods, saving thread processing costs, and large material options for the tie rods. Steel rods and threaded steel bars can be used as long as they can pass through the fixture (usually 10-12mm tie rods), And the length of the pull rod is optional, as long as it is long enough. The construction operation is very convenient, fast, saves nearly 50% of labor compared to threaded pull rods, and can be repeatedly used, with long service life and low maintenance costs! Butterfly card (butterfly buckle), suitable for purlins made of 48 diameter steel pipes, is an alternative product to mountain type cards.
