Cantilever cast-in-place beam hanging basket system dismounting method
The invention discloses a cantilever cast-in-place beam hanging basket system dismounting method. The method comprises the following steps that (1) the connection between the tray and the bottom basket is released, and the tray is lowered to the ground through first and second cranes; (2) the connection between the auxiliary mechanism and the main truss is released, and the third crane is adoptedto hoist the auxiliary mechanism to the designated place on the ground; (3)after the upper cross beam and the lower cross beam are connected through a chain block, and the connection between an anchoring mechanism and the upper cross beam is released; (4) the longitudinal beam, the bottom die, the side die and the lower cross beam are lowered to the position 100 cm away from the ground through thefirst crane and the second crane, the side die is horizontally pulled out and lifted to the designated place by the third crane, and then the longitudinal beam, the bottom die and the lower beam arelowered to the ground; (5) the main truss and the upper cross beam are hoisted to a designated place on the ground through the first crane and the second crane; and (6) the walking track is hoisted tothe designated place on the ground through the third crane, so as to finish the construction. The construction efficiency of the cantilever cast-in-place beam is improved, the construction period ofthe cantilever continuous beam is greatly shortened, and waste of manpower and material resources is reduced.
本发明公开了一种悬臂现浇梁挂篮系统拆除方法，包括如下步骤：①解除托盘与底篮的连接，通过第一、二吊车将托盘下放至地面②解除附属机构和主桁架的连接，采用第三吊车将附属机构吊装至地面指定地点③通过倒链连接上、下横梁后，解除锚固机构与上横梁的连接④通过第一、二吊车将纵梁、底模、侧模和下横梁下放至离地面100cm处，再通过第三吊车将侧模水平抽出并吊装至指定地点，之后，将纵梁、底模和下横梁下放至地面⑤通过第一、二吊车将主桁架、上横梁吊装至地面指定地点⑥通过第三吊车将走行轨道吊装至地面指定地点，完成施工。本发明提高了悬臂现浇梁的施工工效，大大了缩短悬臂连续梁的施工周期，减少人力、物力的浪费。
