Plugging structure of tower crane hole and construction method thereof

Abstract

The invention relates to a plugging structure of a tower crane hole and a construction method thereof. The plugging structure comprises at least one pair of embedded parts embedded in a floor slab, a supporting frame arranged at the hole in a blocking mode, a formwork plugged at the hole and a concrete structure poured on the formwork, wherein the embedded parts are oppositely arranged on the edges of the two opposite sides of the hole of the floor slab; the supporting frame is arranged at the bottom of the floor slab and fixed to the embedded parts; the formwork is arranged on the supporting frame; and the concrete structure is fixedly connected with the floor slab on the edge of the hole. According to the plugging structure of the tower crane hole and the construction method thereof, the embedded parts are arranged in the floor slab, the supporting frame is fixedly connected with the embedded parts, the formwork is arranged on the supporting frame, formwork supporting is achieved, the surface of the concrete structure poured on the formwork is flush with the top of the floor slab 10, and the plugging quality of the tower crane hole in the floor slab is ensured; and plugging construction of holes of multiple layers of floor slabs can be conducted simultaneously, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a plugging structure for a tower crane opening and a construction method thereof. Background technique [0002] In building construction, a square opening will be reserved on the floor when installing the tower crane. After the removal of the tower crane is completed, the hole needs to be sealed. [0003] In the prior art, scaffolding is set up at the bottom of the hole to support the formwork, and concrete is poured on the formwork and fixed to the original floor to seal the hole. [0004] When the opening of the tower crane passes through multi-layer floors, scaffolding needs to be erected layer by layer from bottom to top, formwork is erected layer by layer and poured for sealing. Inadequate construction and reinforcement of formwork frames will easily affect the flatness of the floor, resulting in low efficiency and waste of manpower and material resources. Contents of...
