Hoistway inner hoisting frame for core tube elevator shaft steel beam installation and steel beam construction method

Abstract

The invention relates to a hoistway inner hoisting frame for core tube elevator shaft steel beam installation. A hoisting frame body is arranged in an elevator shaft of a core tube shear wall, and the hoisting frame body is a rectangular frame and comprises six layers; the bottommost layer is used for elevator steel beam installation, and the floor height of the bottommost layer is the standard floor height of a building; and the upper five layers are used for concrete structure construction, steel bar binding and form erecting and removing are sequentially conducted from top to bottom, and the layer height of each of the upper five layers is half of that of the bottommost layer. According to the hoisting frame, the construction measure cost is effectively reduced; and the construction progress is quickened, elevator steel beams and an elevator shaft concrete structure are synchronously constructed, and waiting for elevator shaft capping is not needed.

Description

technical field [0001] The invention relates to the field of steel structure and concrete structure construction, in particular to a hoistway inner lifting frame and a steel beam construction method for installing steel beams in a core tube elevator shaft. Background technique [0002] Due to structural and architectural needs, super high-rise buildings are mostly arranged with core tube shear walls, and the elevator shaft is arranged in the core tube shear walls. In order to facilitate the welding and fixing of elevator guide rails and the convenience of climbing formwork construction, box-shaped or H-shaped steel beams are mostly used to separate the elevator and fix the guide rails in the elevator shaft, and the embedded parts are pre-embedded on the concrete shear wall. Post welded elevator steel girders. After the climbing form climbs, the embedded parts are exposed, and the steel beams in the elevator shaft need to be welded. Due to the high height of the hoistway an...

AI Technical Summary

Problems solved by technology

Due to the high height of the hoistway and no attachment point, it is impossible to provide a construction work surface. In addition, the steel beam of the elevator cannot be hoisted from above due to the blocking of the climbing formwork, so it can only be installed with a winch or a chain block

The construction in the shaft is highly dangerous and the construction efficiency is low

The traditional construction method adopts scaffolding construction. Every time a steel beam is installed, a section of scaffolding needs to be erected. After the construction is completed, it needs to be dismantled, and the attachment position of the scaffolding needs to be reserved in advance. The construction is extremely cumbersome
