On the contrary, when an element is said to be "directly" connected to another element, there are no intermediate elements.

[0033] like Figure 1 As shown, in a preferred embodiment of the utility model, a device for lifting a hanging steel column is provided, including a first hanging plate 1, a second hanging plate 2, a card plate lifting ear 3, a connecting ear plate 4, an assembly card plate 5, a first lifting device 6 and a second lifting device 7.

[0034] In the device provided by the present invention, the first hanging plate 1 and the second hanging plate 2 have the same structure, both of which are composed of a long side and a short side to form an L-shaped structure. In this embodiment, the first hanging plate 1 and the second hanging plate 2 are both made of L-shaped steel plates. In order to improve the bearing capacity of the hanging plates, the plate thickness is not less than 6mm.

[0035] like Figure 2 As shown, the long sides of the first hanging plate 1 and the second hanging plate 2 are arranged on the upper surface of the upper flange of the steel beam 10, and the short sides of the first hanging plate 1 and the second hanging plate 2 are respectively on both sides of the upper flange of the steel beam 10 and vertically downward. Here, the upper steel beam 10 has been hoisted.

[0036] In the device provided by the present invention, a plurality of first connection holes 1-1 are provided at intervals on the long side of the first hanger plate 1, and a plurality of second connection holes 2-1 are provided at intervals on the long side of the second hanger plate 2. The first connecting member 8 passes through the first connection hole 1-1 on the first hanger plate 1 and the second connection hole 2-1 of the second hanger plate 2 to be fixedly connected, connecting the first hanger plate 1 and the second hanger plate 2 into a "concave"-shaped structure hung upside down on the upper surface of the upper flange of the steel beam 10. By passing the first connecting member 8 through different first connection holes 1-1 and second connection holes 2-1, the distance between the short sides of the first hanger plate 1 and the second hanger plate 2 is adjusted, so that the first hanger plate 1 and the second hanger plate 2 are suitable for steel beams 10 of different widths.

[0037] In order to connect the upper hoisted steel beam 10 and the lower hanging steel column 11 through the hoisting device, in the device provided by the present invention, a first through hole 1-2 for connecting the first hoisting device 6 is provided on the short side of the first hanging plate 1, and a second through hole 2-2 for connecting the second hoisting device 7 is also provided on the short side of the second hanging plate 2. In this embodiment, the first hoisting device 6 and the second hoisting device 7 are both hand chain hoists.

[0038] The hand chain hoist is a manual lifting device with a simple structure and convenient to carry. The operator only needs to pull the hand chain with a slight force to achieve lifting and lowering. Therefore, in this embodiment, no large lifting machinery is required, and only a small lifting device and manual labor are used to lift the lower hanging steel column into place.

[0039] In the device provided by the present invention, the card plate lifting ear 3 is fixed on one side of the top of the lower hanging steel column 11, and the card plate lifting ear 3 is provided with a third through hole 3-1 for connecting the second lifting device 7. The connecting ear plate 4 is fixed on the other side of the top of the lower hanging steel column 11. The arrangement direction of the connecting ear plate 4 is parallel to the long side of the second hanging plate 2, and a plurality of fixing holes 4-1 are provided on the connecting ear plate 4 at intervals. The assembly card plate 5 is arranged on the same side of the connecting ear plate 4, and the assembly card plate 5 is provided with a third connecting hole 5-1 for connecting with the connecting ear plate 4.

[0040] In this embodiment, the card plate lifting lug 3 and the assembly card plate 5 are both made of L-shaped steel plates with a thickness of not less than 6 mm. The connecting lug plate 4 is made of rectangular steel plates with a thickness of not less than 6 mm. The card plate lifting lug 3 and the connecting lug plate 4 are respectively fixed to the two sides of the top of the hanging steel column 11 by welding.

[0041] In the device provided by the present invention, the plate lifting lug 3 and the assembly plate 5 are both L-shaped structures consisting of a long side and a short side, and the short sides of the plate lifting lug 3 and the assembly plate 5 are both located above the upper surface of the lower hanging steel column 11. When the lower hanging steel column 11 is hoisted below the steel beam 10, the plate lifting lug 3 and the short sides of the assembly plate 5 are used to clamp the lower flange of the steel beam 10.

[0042] The second connecting member 9 passes through the third connecting hole 5-1 on the assembly card plate 5 and the fixing hole 4-1 on the connecting ear plate 4, and adjusts the distance between the card plate lifting ear 3 and the long side of the assembly card plate 5, so that the card plate lifting ear 3 and the assembly card plate 5 are suitable for steel beams 10 of different widths. The remaining fixing holes 4-1 on the connecting ear plate 4 can be used as lifting points for connecting the first lifting device 6.

[0043] like Figure 1As shown, in this embodiment, three first connection holes 1-1 with equal spacing are provided on the long side of the first hanging plate 1, and three second connection holes 2-1 with equal spacing are provided on the long side of the second hanging plate 2. Three fixing holes 4-1 with equal spacing are provided on the connecting ear plate 4. Those skilled in the art can provide appropriate connection holes on the long side of the first hanging plate 1, the long side of the second hanging plate 2 and the connecting ear plate 4 according to the actual situation of the construction site and the specific sizes of the steel beam 10 and the hanging steel column 11.

[0044] In this embodiment, the first connecting member 8 and the second connecting member 9 are both bolts. The first connecting member 8 passes through the first connecting hole 1-1 and the second connecting hole 2-1, so that the first hanging plate 1 and the second hanging plate 2 are detachably connected. The second connecting member 9 passes through the third connecting hole 5-1 and the fixing hole 4-1, so that the assembly card plate 5 and the connecting ear plate 4 are detachably connected.

Figure 4 shown.

[0047] (2) The first lifting device 6 is arranged between the first hanging plate 1 and the card plate lifting ear 3, and the second lifting device 7 is arranged between the second hanging plate 2 and the connecting ear plate 4. The hole position for installing the second lifting device 7 on the connecting ear plate 4 needs to be staggered in advance with the hole position for installing the assembly card plate 5. Figure 5 shown.

[0048] (3) The first lifting device 6 and the second lifting device 7 are used to lift the lower hanging steel column 11. After the lower hanging steel column 11 is lifted to the position directly below the lower flange of the steel beam 10, the short side of the clamping plate lifting lug 3 is placed on the upper surface of the lower flange of the steel beam 10 and clamped. Figure 6 shown.

[0049] (4) According to the width of the steel beam 10, select the appropriate fixing hole 4-1, use bolts to connect the assembly clamp 5 and the connecting ear plate 4 into a whole, so that the short side of the assembly clamp 5 is placed on the upper surface of the lower flange of the steel beam 10 and is clamped. Figure 7 shown.

[0050] (5) Temporarily spot-weld the lower hanging steel column 11 and the steel beam 10, release the connection between the first lifting device 6 and the second lifting device 7, and remove the first hanging plate 1 and the second hanging plate 2. Figure 8 shown.

[0051] The above-described embodiment is only a preferred solution of the present invention, but it is not intended to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present invention.
