Hoisting structure for assembly type composite floor slab

Abstract

The hoisting structure comprises a hoisting plate and hoisting supports which are symmetrically arranged on the two sides of the bottom of the hoisting plate, the length direction of the hoisting supports is perpendicular to the length direction of the hoisting plate, and an overturning hoisting tool is installed at the bottom of any hoisting support; the overturning lifting appliance comprises sliding rails which are laid in the length direction of the lifting support and located at the two ends of the lifting support respectively, sliding blocks correspondingly embedded in the two sliding rails in a sliding mode, synchronous overturning motors correspondingly installed at the bottoms of the two sliding blocks, lifting wheels connected to the output ends of the synchronous overturning motors, and synchronous lifting belts connected to the outer surfaces of the two lifting wheels in a sleeving mode. The clamping parts are symmetrically arranged in the synchronous lifting belt and are used for fixing a plate body; when the synchronous lifting belt lifts the precast slab, the synchronous lifting belt can wrap the two ends of the precast slab, and the stressed steel bar ends at the two ends of the precast slab are clamped and fastened through the clamping parts, so that when the synchronous lifting belt lifts the precast slab, connection between the synchronous lifting belt and the precast slab is more stable, and the precast slab is safer to lift.

Description

technical field [0001] The invention relates to the technical field of hangers in the construction industry, in particular to a hoisting structure for a prefabricated laminated floor slab. Background technique [0002] Under the industry background of "vigorously developing prefabricated buildings, promoting the transformation and upgrading of traditional construction models, and realizing building industrialization and residential industrialization", prefabricated floors are widely used in prefabricated buildings. At present, the prefabricated floor slabs commonly used and widely used in my country are truss reinforced concrete prefabricated slabs (hereinafter referred to as prefabricated slabs). At the construction site, when lifting and transporting prefabricated panels, most of them use tower crane wire ropes to lift prefabricated panels, but this way of hoisting still has many inconveniences in specific use: [0003] (1) When the steel wire rope is hoisting the prefabri...

AI Technical Summary

Problems solved by technology

[0003] (1) When the steel wire rope is hoisting the prefabricated slab, the steel wire rope is connected to the suspension point on the slab body through the hook, so when the prefabricated slab is connected to the hook, it is only a point-to-point connection, which causes insufficient hoisting of the prefabricated slab Stable, only relying on the strength of the suspension point for connection, there is a big safety hazard;

[0004] (2) In the process of hoisting and transshipment, in order to facilitate the subsequent installation of prefabricated panels by construction personnel, it is often necessary to turn over the prefabricated panels. At present, when the precast panels are hoisted and turned over by steel wire rope, most of them rely on the wire rope to move up and down by pulling the hook to realize prefabrication. The slabs are turned over, and in the actual operation, because the bottom of the prefabricated slab is not protected by the limit, the prefabricated slab is prone to displacement and shaking during the turning process, which causes the center of gravity of the prefabricated slab to be unstable, which in turn leads to The overall instability of the prefabricated panel affects the use effect of the spreader
