Technical Field

The utility model belongs to the technical field of building construction, particularly relates to hoisting and positioning of an outer wall ALC plate, and particularly relates to a special hoisting tool for hoisting an outer wall ALC plate.

Background

ALC is a short name of Autoclaved Lightweight Concrete (Autoclaved Lightweight Concrete), and is one of high-performance Autoclaved aerated Concrete (ALC). The ALC board is a porous concrete forming board (reinforced with processed reinforcing steel bars) which is formed by curing fly ash (or silica sand), cement, lime and the like serving as main raw materials through high-pressure steam. The ALC board can be used as a wall material and a roof board, and is a novel building material with excellent performance.

When the ALC board is used as an outer wall material, an important working procedure is the lifting of the ALC board, the conventional lifting method adopts a steel wire rope and a transverse short steel bar, but the method has a serious problem that the short steel bar in the lifting method has the possibility of falling off when the steel wire rope is loosened after the batten is initially in place, and has great potential safety hazard.
