Background technique

With the implementation of construction industrialization, the use of prefabricated components is becoming more and more extensive. Building industrialization refers to the use of modern management models to realize the generalization of building components and the assembly and mechanization of on-site construction through standardized architectural design and modularized and factory-like production of parts. The components are prefabricated in the factory, and the construction process can be carried out on site and in the factory at the same time. Most of the work has been completed in the factory, and the time for on-site installation is very short. Especially in the concrete construction process that is highly dependent on the weather, the production of factory precast concrete components adopts the method of rapid maintenance, which greatly shortens the maintenance time compared with the cast-in-place method.

However, the currently used hoisting tools for industrialized prefabricated components are poor in flexibility, and the components are unevenly stressed, causing cracks in the prefabricated components during the hoisting process, especially for components with large horizontal dimensions such as steel truss prefabricated panels, the hoisting tools cannot be adjusted flexibly , There are many cracks during the hoisting process.

Among the plurality of fixed seats, fixed end locks are installed on the fixed seats at both ends, and fixed pulleys are fixedly installed on the other fixed seats. The number of fixed pulleys can be selected according to the hoisting requirements; The two ends of the movable pulley are respectively fixed to the fixed end lock. The movable pulley and the fixed pulley are arranged at intervals to form a plurality of pulley blocks. The lower part of the movable pulley is fixed with a hook, and the movable pulley and the hook hang under their own weight. The pulley block is automatically adjusted according to the center of gravity of the prefabricated slab to ensure that the prefabricated slab is evenly stressed when it is hoisted.

Preferably, the lock at the fixed end is a shackle, which is convenient for obtaining materials and easy for installation.

Preferably, the fixed pulley is also fixed on the hanger through a shackle, which simplifies the structure and facilitates installation.

Preferably, the fixing seats at both ends are respectively located at the two ends of the hanging beam, making full use of the structure of the hanging beam to achieve the best lifting effect.

Preferably, there are four lifting lugs, which are evenly distributed on the hanging beams on both sides. When there are at least two supporting beams, the four lugs are located at the joints between the supporting beams and the hanging beams at both ends.

Preferably, both the fixing seat and the lug plate are made of steel plates, the steel plates are welded and fixed on the hanging beam, and lifting holes or connection holes are processed on the dry plate for lifting or connecting shackles.

Preferably, the hanging beam, the supporting beam and the supporting legs are all made of I-beams, which are welded and fixed to each other; To achieve a similar effect, the processing material can be selected according to the use environment.

Compared with the prior art, a prefabricated slab hoisting tool for steel truss of the utility model has the following beneficial effects:

The tool is simple in structure, flexible and convenient to use. Through the combined use of the wire rope and the pulley block, the automatic adjustment of the movable pulley on the wire rope avoids the problems of uneven stress on the prefabricated panels and non-adjustable levelness caused by direct hoisting of the wire rope. During the process, the automatic adjustment of the pulley block is used to make the prefabricated slab of the hoisted steel truss evenly stressed, which effectively protects the prefabricated slab from cracking and reduces the damage rate;

The number of lifting points can be increased or decreased according to the size and characteristics of the prefabricated steel truss slab to be hoisted, so it has good flexibility in use;

Using this tool, when the steel truss prefabricated slab is hoisted, the force is uniform and the levelness can be adjusted flexibly. When it encounters a floor opening, it can be tilted and lifted with the cooperation of the operator, and it can pass through the floor opening smoothly.
