Abstract
The invention relates to an open type hoisting clamp used for slender components and a construction method. Hoisting lugs are welded to a top beam. The top beam is fixedly connected with a bottom beam through a vertical beam, and the open type hoisting clamp is formed. During hoisting, a hoist hoists the two hoisting lugs of the open type hoisting clamp through two steel wire ropes correspondingly and controls the open type hoisting clamp to approach the side face of a slab beam in the horizontal direction, the slab beam is clamped, and the side face of the slab beam is made to abut against a backing plate of the open type hoisting clamp. When double-hoist hoisting is adopted, during hoisting and rotating, a first hoist turns right firstly, then a second hoist turns left to keep pace with the first hoist, the slab beam penetrates through the second hoist; when the slab beam is dropped by hoisting, the slab beam should be advanced towards the side face of a former slab beam in the opening direction of the open type hoisting clamp, gaps are not allowed between the connected slab beams, and the slab beam is put in position at a time. By adopting the novel clamp for hoisting, the problem that positioning is difficult through common closed type clamps during slab beam hoisting is solved, the hoisting speed is greatly increased, and the effect of reducing cost is achieved.
