Document Type and Number:
WIPO Patent Application WO/2014/114027
Kind Code:
A1
Abstract:
Disclosed is a fastening structure device used for fast assembly concrete formwork. The device comprises a fastening plate (10) and a locking member (20), wherein one end part of the fastening plate (10) is provided with a clip pin (11) and the other end part of the fastening plate (10) is provided with a sleeve (12), the locking member (20) comprises a matching bolt (21) and nut (22), the bolt (21) passes through the inside of the sleeve (12) and two ends thereof both pass out of the sleeve (12), the nut (22) is mounted on one end of the bolt (21) located outside the sleeve (12), and a spring bolt (23) is fixed on an end part of the other end of the bolt located outside the sleeve (12). Further disclosed is a fastening structure device used for fast assembly concrete formwork for fixing together two blocks of concrete formwork. When erecting concrete formwork on an assembled fixing tube, the fastening plate (10) is clamped on the fixing tube, the clip pin (11) and the spring bolt (23) are respectively clamped in a fast assembly groove on the concrete formwork, and rotating the nut (22) tightly clamps the spring bolt (23) in the fast assembly groove (11a). After waiting until the concrete has been formed, rotating the nut (22) in the reverse direction loosens the spring bolt (23) from the fast assembly groove (11a), and then the fixing tube and the concrete formwork can be detached from one another. By means of a nut (22) and a bolt, the device tightly clamps the spring bolt (23) in the fast assembly groove, thereby improving the tightness.
