Self-stabilizing operating platform for elevator shaft

Abstract

The invention discloses a self-stabilizing operating platform for an elevator shaft, which comprises an upper layer platform, a longitudinal support frame, a diagonal bracing support and a lower layer platform, wherein the upper layer platform is in a square shape, and the area is slightly smaller than the cross sectional area of the elevator shaft; the area of the lower layer platform is smallerthan that of the upper layer platform; one side, which is close to an elevator door, of the lower layer platform and the corresponding side of the upper layer platform are positioned in the same vertical plane; upper and lower ends of the diagonal bracing support are respectively fixed to one side, which is away from the elevator door, of the upper and lower layer platforms; rectangular support legs for being clamped at the external corner of a wallboard at an elevator opening are arranged on one side, which is close to an elevator door, of the lower layer platform; hanging rings are respectively arranged at four corners of the upper layer platform, the height of the two hanging rings close to one side of the elevator door is greater than that of the two hanging rings away from one side of the elevator door; and when the platform is hoisted, and the top of each hanging ring is positioned at the same height, the rectangular support legs are positioned in the elevator shaft. The operating platform is simple in machining, and can realize self-stabilization and can be used repeatedly, and the safety of the platform is increased by fixed bolts of the upper layer platform.

Description

technical field [0001] The invention relates to the field of building structure construction, in particular to a self-stabilizing operating platform for an elevator shaft. Background technique [0002] In the construction of traditional building elevator shaft structures, steel pipes, fasteners and scaffolding are generally used to tie up from the bottom to the top floor as an operating platform for the shear wall formwork of the elevator shaft, or a single-layer channel steel splicing platform is used. Rely on the support bolts to achieve a stable effect. The former occupies a large amount of steel pipes and pipe clamps, wastes a lot of labor and is unsafe; the latter is affected by the strength of the supporting bolts, the strength of the wall concrete at the support, and the illegal operation of the operator, which is very prone to safety accidents caused by the platform falling.
