Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to an adjustable hoisting and positioning device for prefabricated buildings. Background Technology

[0002] With the rapid development of China's economy and construction industry, the construction of residential buildings is also moving towards large-scale, high-quality, pollution-reduced, and sustainable development. The shortcomings and problems of traditional cast-in-place concrete structures have hindered the large-scale industrial production of buildings. Prefabricated buildings can divide buildings into various component modules, which are prefabricated in factories and then transported to the site for installation in various states, connection of nodes, and partial casting and assembly into the whole prefabricated structure. However, precise docking must be ensured when prefabricated components are hoisted.

[0003] Chinese patent discloses a method for hoisting and positioning prefabricated buildings (publication number CN117722033A). This patented technology uses a locator to replace the traditional method of workers using pry bars to drive prefabricated stairs for auxiliary positioning. The positioning is very convenient and quick to assemble and disassemble, and no further force is required after installation, which can greatly reduce the labor intensity of workers. Secondly, the use of a locator reduces the degree of worker involvement, thus effectively reducing construction safety hazards. Positioning can be achieved in one go using the locator, saving positioning time and improving positioning efficiency and accuracy. However, its application is limited, the through holes on the hoisted prefabricated components must be penetrated, and the extension range of the spring is limited. Utility Model Content

The circular sleeve 41 is sleeved on the fixed shaft 2, and the circular sleeve 41 and the fixed shaft 2 are fixedly connected by the pre-tightening screw 42. After loosening the pre-tightening screw 42 counterclockwise, the entire positioning assembly 4 can be rotated along the fixed shaft 2; after loosening the pre-tightening screw 47 counterclockwise... Then, the length of the inner slide rod 46 inside the outer sleeve 48 can be adjusted, thereby adjusting the position of the arc-shaped cylinder 1 43 and the arc-shaped cylinder 2 45, so that the center of the arc-shaped cylinder 1 43 and the arc-shaped cylinder 2 45 corresponds to the center of the reserved hole 8 at the lower end of the precast component 2 9.

When the lifting device lifts the precast component 2 9, the winch moves with the lifting device.

[0024] The working principle of this utility model is as follows: During the assembly process, the prefabricated component 6 has been installed. The prefabricated component 9 needs to be hoisted onto the prefabricated component 6, and the embedded rib 7 at the upper end of the prefabricated component 6 should be inserted into the corresponding reserved hole 8 at the lower end of the prefabricated component 9.

At the same time, the winch winds up the wire rope 35, and the lower end of the wire rope 35, as well as the arc buckle 1 31 and the wire rope 35, are fixed to the embedded rib 7 at the upper end of the precast component 1 6 to position the precast component 2 9. When the precast component 2 9 slowly falls, the arc cylinder 1 43 and the arc cylinder 2 45 can be sleeved on the embedded rib 7 at the upper end of the precast component 1 6.

[0029] At this point, loosen the fastening bolt 32 counterclockwise, separating the arc-shaped buckle 31, arc-shaped buckle 33, and wire rope 35 from the embedded reinforcement 7; and pull the wire rope 35 out from between the arc-shaped cylinder 43 and the arc-shaped cylinder 45; the lifting device and precast component 9 continue to fall, and the embedded reinforcement 7 at the upper end of the precast component 6 continues to move upward between the arc-shaped cylinder 43 and the arc-shaped cylinder 45, entering the reserved hole 8 at the lower end of the precast component 9. At this point, loosen the fastening screw 44, the pre-tightening screw 47, and the pre-tightening screw 42 counterclockwise, moving the entire positioning assembly 4 away from the precast component 6 and the precast component 9; the lifting device and precast component 9 continue to fall, and the precast component 9 can be accurately installed on the precast component 6. Then, the entire lifting and positioning device can be removed.
