Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a prefabricated plate hanging device. Background Art

[0002] Vertical transportation is crucial in prefabricated buildings. The process requires ensuring the safe and smooth lifting of prefabricated components while minimizing damage to the component materials. One existing lifting device uses a chain that connects one end of the prefabricated component to the other directly to a tower crane hook. This type of chain typically requires an angle between 45° and 60° between the chain and the component, but when the component is too large, the chain angle becomes inconspicuous and fails to meet the lifting requirements. Another method involves lifting the chain at a perpendicular angle to the component, using a steel beam with lifting points. However, this single lifting point arrangement cannot accommodate the diverse sizes of prefabricated components. Summary of the Invention

[0003] The utility model aims to solve the problem in the prior art that a single lifting point cannot meet the lifting construction requirements of PC components of different sizes, and provides an assembled PC precast concrete component lifting device to adapt to the lifting construction of PC components of different specifications and sizes.

[0004] The technical solution of this utility model:

[0005] A prefabricated PC concrete component lifting device includes a rectangular lifting frame composed of a vertical channel steel beam 3 and a transverse channel steel beam 9. Steel bar hanging points 7 are distributed on the vertical channel steel beam 3 or the transverse channel steel beam 9. A movable hanging ring 8 is positioned through the steel bar hanging points 7. A chain 5 and a lower hook 6 are installed at the lower end of the movable hanging ring 8.

[0006] The movable hanging ring 8 is a rectangular frame structure with a positioning hole on the top of the frame structure. The inner wall width of the frame structure is equal to the width of the vertical channel steel beam 3 or the horizontal channel steel beam 9. The vertical height of the frame structure is greater than the vertical height of the steel bar hanging point 7 plus the vertical channel steel beam 3 or the horizontal channel steel beam 9.

[0007] A rectangular hoisting frame is composed of at least four vertical channel steel beams 3 and four horizontal channel steel beams 9. Hanging plates 10 are welded at four symmetrical cross intersections, and the steel wire rope 2 and the steel wire rope lock 1 are installed through the hanging plates 10.

[0008] The lower end of the movable hanging ring 8 is provided with a lifting lug, and the upper hook 4 at the upper end of the chain 5 cooperates with the lifting lug.

[0009] The vertical channel steel beams 3 and the transverse channel steel beams 9 are cross-separated into multiple sections. The upper surface of each section of the vertical channel steel beam 3 or the transverse channel steel beam 9 is evenly distributed with 4-10 steel bar hanging points 7 and configured with 1-2 movable hanging rings 8.

[0010] A QR code is set on each PC board component.

[0011] Beneficial effects of the utility model:

[0012] 1. Provide an assembled PC precast concrete component lifting device based on BIM technology to accommodate the lifting and construction of PC components of different specifications and sizes. Smooth lifting ensures construction safety, avoids collisions and material damage during component lifting, and improves the lifting efficiency of PC precast concrete components. This lifting device can be processed and installed on-site and can be reused to save costs.

[0013] 2. This lifting device is equipped with a movable hanging ring 8 and multiple steel bar hanging points 7 on the basis of the traditional original one. The movable hanging ring 8 is 5cm higher than the steel beam to facilitate better movement and hanging on the corresponding steel bar hanging point 7. The traditional steel beam has only fixed hanging points, which is not conducive to lifting PC components of different specifications.

[0014] 3. BIM technology will be used to repeatedly analyze the structure of the lifting device, and finally the optimal solution for the device will be selected; BIM technology will also be used to deepen the design of PC prefabricated components. A QR code will be set in each PC board component, and construction workers can quickly obtain component information by scanning with their mobile phones, so that on-site lifting work can be carried out more smoothly, improving construction efficiency and ensuring construction progress.

[0015] 4. The steel beam part can be processed on the construction site, and the rest can be purchased and transported to the construction site as needed for assembly with the on-site processed components. After assembly, the device can be sprayed with anti-rust paint to increase its service life and save resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Example 1:

[0023] like Figure 1A rectangular lifting frame is formed by four vertical channel steel beams 3 and five horizontal channel steel beams 9. Hanging plates 10 are welded at four symmetrical cross points in the middle of the lifting frame, and steel wire ropes 2 and steel wire rope locks 1 are installed on the hanging plates 10.

[0024] This lifting device is equipped with a movable hanging ring 8 and multiple steel bar hanging points 7 on the basis of the traditional original one. In this embodiment, a row of steel bar hanging points 7 are arranged at a certain interval on the upper surface of each transverse channel steel beam 9. The movable hanging ring 8 is a rectangular frame structure with a positioning hole on the top of the frame structure. The inner wall width of the frame structure is equal to the width of the transverse channel steel beam 9. The vertical length of the movable hanging ring 8 frame structure is 5 cm larger than the vertical length of the steel beam. The height of the steel bar hanging point 7 is about 4 cm, so that it can be better moved and hung on the corresponding steel bar hanging point 7. The traditional steel beam only has fixed hanging points, which is not conducive to lifting PC components of different specifications.

[0025] The steel beam parts 3 and 9 of the device can be processed at the construction site; the remaining parts can be purchased and transported to the construction site as needed for assembly with the on-site processed components. After assembly, the device can be sprayed with anti-rust paint to increase its service life and save resources.

[0026] The vertical channel steel beam 3 and the transverse channel steel beam 9 are welded by electric welding. Four hanging plates 10 are arranged horizontally and vertically at the intersection of the steel beams and drilled. The steel wire rope is passed through the hanging plates 10 and around the tower crane hook and locked with a wire rope lock 1.

[0027] According to the size of the PC component, multiple steel bar hanging points 7 are welded on the steel beam; movable hanging rings 8 are welded with steel plates and holes are drilled at the top and bottom hanging plates so that the upper ends of the movable hanging rings 8 can be hung on any steel bar hanging point 7; the movable hanging rings are set between the cross-welding points of the transverse channel steel beam 9 and the vertical steel beam 3; the upper hook 4 and the lower hook 6 are connected to the steel chain to form a steel chain rope, which can move simultaneously with the movable hanging ring 8, and the lower hook 6 is connected to the hanging point of the PC concrete component.

[0028] When the PC components have different sizes, they can be lifted vertically by mobilizing the movable hanging ring 8, and the lifting chain is kept in a vertical state for lifting, so that the lifting safety is guaranteed and the lifting construction efficiency is improved.
