Rear-mounted eccentric screw system for formwork erection
The invention discloses a rear-mounted eccentric screw system for formwork erection, and belongs to the technical field of formwork erection of buildings. When crossed longitudinally and transversely, the existing screws for formwork erection can intervene to one another and are single in function. The rear-mounted eccentric screw system for formwork erection comprises a double-end screw, round nuts, outer screws, a shaping square stopper, eccentric guide sleeves and a chuck, wherein the round nuts are connected to two ends of the double-end screw; the outer screws are connected to the round nuts; bayonet locks are fixed on the outer screws; positioning through holes which correspond to through holes of screws on a formwork are formed in the shaping square stopper; the eccentric guide sleeves can be rotatably placed in the positioning through holes of the shaping square stopper; each eccentric guide sleeve is provided with an eccentric adjusting hole; the outer screws and the bayonet locks can penetrate in the eccentric adjusting holes of the eccentric guide sleeves; the chuck is provided with through holes; the outer screws and the bayonet locks can penetrate in the through holes; and the chuck rotates so that the bayonet locks are clamped at the edges of the through holes. During formwork erection, the eccentric guide sleeves rotate so as to adjust skewing of the outer screws, the circumstance that the screws which are crossed longitudinally and transversely intervene to one another is avoided, the screw can be mounted at the rear of the formwork, and the rear-mounted eccentric screw system is convenient and flexible to operate; and moreover, the rear-mounted eccentric screw system has effects of pulling the formwork, supporting the formwork when the formwork is mounted and assisting in detachment of the formwork when the formwork is detached.
