MACHINE FOR REMOVING FORMWORK FROM CEILING STRUCTURE
20230009876 · 2023-01-12 ·

A machine for removing beams from underneath formwork at an underside of a concrete slab includes a wheeled base movable on and supported at a support structure, a raisable-and-lowerable structure disposed on the wheeled base, and a beam-removal device coupled to the raisable-and-lowerable structure. The beam-removal device includes a beam-gripping mechanism. With the raisable-and-lowerable structure raised to position the beam-removal device at a beam that supports the formwork at the underside of the concrete slab, the beam-gripping mechanism operates to grasp the beam. With the beam grasped by the beam-gripping mechanism, the machine is operated to remove the beam from the formwork.

A machine for removing formwork from underneath a concrete slab includes a wheeled base movable on and supported at a support structure, a raisable and lowerable structure disposed on the wheeled base, and a formwork-removal device attached to the raisable and lowerable structure. The formwork-removal device includes (i) an arm extending from the raisable and lowerable structure and (ii) at least one pneumatic gripper disposed at a distal end of the arm. With the raisable and lowerable structure adjusted to position the pneumatic gripper under the formwork and engaged with the formwork, and when the pneumatic gripper is activated, the pneumatic gripper applies a suction to secure the formwork at the pneumatic gripper. With the formwork secured at the pneumatic gripper, and when the pneumatic gripper is lowered, the pneumatic gripper applies a separating force to the formwork to remove the formwork from the concrete slab.

Machine for removing formwork from ceiling structure

A machine for removing formwork from underneath a cured concrete slab includes a wheeled base movable on and supported at a support structure, a raisable-and-lowerable structure disposed on the wheeled base, and a formwork-removal device attached to the raisable-and-lowerable structure. The formwork-removal device includes an arm extending from the raisable-and-lowerable structure, at least one wedge element disposed at a distal end of the arm, and a formwork-retaining mechanism. With the raisable-and-lowerable structure adjusted to raise the wedge element and the wedge element moved to engage the formwork and an underside of a concrete slab, the wedge element is further moved to apply a force separating part of the formwork from the concrete slab, the formwork-retaining mechanism is operated to grasp the formwork separated from the concrete slab, retaining the formwork. With the formwork grasped by the formwork-retaining mechanism, the raisable-and-lowerable structure is lowered, removing the formwork from the concrete slab.
