[0002] With large-scale infrastructure construction underway across the country, building designs are becoming increasingly complex and diverse, with a plethora of innovative design concepts emerging, leading to the widespread use of steel structures. Against this backdrop, controlling the quality of steel structure installation has become particularly crucial.

[0003] According to incomplete statistics, during the construction of steel structures, two steel beams need to be horizontally connected. The steel beams are generally I-beams. In principle, when two steel beams are connected, the upper and lower flanges of the two steel beams need to be horizontally aligned.

[0004] However, the problem is that after two adjacent steel beams are installed, the probability of a height difference explosion point reaches 70%, and there is currently no convenient and reliable device on the market to accurately adjust the deviation of the steel beams. Utility Model Content

[0005] This utility model provides a steel structure beam hoisting and leveling device to solve the problem of the inability to adjust the height difference between steel beam joints, and to accurately control the steel beams during installation to ensure the quality of the project.

[0006] This utility model is achieved through the following technical solution:

[0007] A steel structure beam hoisting and leveling device includes a pressing device and a positioning device. The pressing device includes a protective shell and a lifting device, and the upper end of the lifting device is fixed to the top inside the protective shell.

[0008] The positioning device includes a laterally distributed housing, and a positioning cavity with a rectangular cross-section is provided inside the housing. The positioning cavity allows the upper flange of the I-beam to pass through. The bottom of the housing has a notch along the length direction that allows the web of the I-beam to pass through.

[0009] The device housing is provided with a support, the top of which is connected to the bottom of the lifting device, and the bottom of the support is provided with a third connecting plate.

[0010] Furthermore, the lifting device is a jack, the base of which is fixed to the top surface of the support, and the top of which is fixed to the top of the protective housing.

[0011] The protective housing has vertically distributed elongated holes on its side wall, and the jack's operating lever extends through these elongated holes to the outside of the protective housing.

[0012] Furthermore, it also includes a first connecting plate, which has a mounting port. The outer bottom end of the protective shell is fitted onto the mounting port of the first connecting plate and is fixedly connected to the first connecting plate.

[0013] The outer casing of the device consists of two second connecting plates, which are C-shaped steel plates. The top horizontal plate of the second connecting plate has multiple bolt mounting holes and is fixed to the bottom surface of the first connecting plate by bolts.

[0014] Furthermore, the bolt mounting hole is a slotted hole.

[0015] Furthermore, the support is connected to the third connecting plate by welding.

[0016] Furthermore, the protective casing has a handle on top.

[0017] The beneficial effects achieved by this utility model compared with the prior art are as follows:

[0018] A steel structure beam hoisting and leveling device includes a pressing device and a positioning device. The pressing device includes a protective shell and a lifting device, and the upper end of the lifting device is fixed to the top inside the protective shell.

[0019] The positioning device includes a laterally distributed housing, and a positioning cavity with a rectangular cross-section is provided inside the housing. The positioning cavity allows the upper flange of the I-beam to pass through. The bottom of the housing has a notch along the length direction that allows the web of the I-beam to pass through.

[0020] The device housing is provided with a support, the top of which is connected to the bottom of the lifting device, and the bottom of the support is provided with a third connecting plate.

[0021] 1. The steel structure beam hoisting and leveling device of this utility model is assembled at the joint of two I-beams, so that the upper flange plates of the two I-beams are located in the positioning cavity of the device shell. The force is transmitted to the third connecting plate through the lifting device. The third connecting plate squeezes the upper flange plates of the two I-beams, thereby leveling the two I-beams with different heights. The steel beam is precisely controlled during the installation process to ensure the quality of the project.

[0022] 2. The lifting device uses a jack, which can be easily and flexibly controlled to press down using the operating lever, making operation simple;

[0023] 3. The outer shell of the device is composed of two second connecting plates on the left and right. The second connecting plates are C-shaped steel plates. The top horizontal plate of the second connecting plate is provided with multiple bolt mounting holes and is fixed to the bottom surface of the first connecting plate by bolts. This design facilitates the disassembly and assembly of the outer shell of the device and allows for flexible use. The bolt mounting holes are waist holes, which can adjust the notch width of the outer shell of the device to accommodate I-beam web plates of different thicknesses.

[0024] 4. By using the jacking action, the force is transmitted to the third connecting plate and, with the help of the limiting action of the second connecting plate, the two I-beams with different heights are leveled by the pressing action of the flat plate. This standardizes and regulates the steel structure installation operation, improves the work quality, and reduces additional expenses.

[0025] 5. The device is easy to disassemble and can be reused, avoiding material waste and achieving significant economic and environmental benefits. Attached Figure Description

The jacking device includes a protective shell 2, a support 4, and a lifting device. The protective shell 2 is a cylindrical shell. In this embodiment, a jack 3 is used as the lifting device. The base of the jack 3 is fixed to the top surface of the support 4, and the top of the jack 3 is fixed to the top of the protective shell 2 by welding. Vertically distributed elongated holes are machined on the side wall of the protective shell 2. The operating lever of the jack 3 extends to the outside of the protective shell 2 through the elongated holes, allowing the operator to control the movement of the jack 3 from the outside. To facilitate movement of the device, a handle 1 is welded to the top of the protective shell 2.

[0035] To facilitate connection with the positioning device, the first connecting plate 5 is designed as a rectangle with a mounting opening machined at its center. The outer bottom of the protective housing 2 is fitted onto the mounting opening of the first connecting plate 5 and fixedly connected to it by welding. The positioning device includes a horizontally distributed housing. Inside the housing is a positioning cavity with a rectangular cross-section, allowing the upper flange of the I-beam to pass through. The bottom of the housing has a notch along its length to allow the web of the I-beam to pass through. The third connecting plate 8 is located inside the positioning cavity. The bottom of the support 4 is connected to the third connecting plate 8 by welding.

[0036] In this embodiment, for ease of assembly, the device housing consists of two second connecting plates 7, one on the left and one on the right. Each second connecting plate 7 is a C-shaped steel plate, and each C-shaped steel plate includes a vertical plate and a top horizontal plate and a bottom horizontal plate fixed to its upper and lower ends. Multiple bolt mounting holes are machined on the top horizontal plate of the second connecting plate 7, and the plates are fixed to the bottom surface of the first connecting plate 5 by bolts 6. To facilitate adjustment of the spacing between the second connecting plates 7, the bolt mounting holes are designed as slotted holes.

[0037] The specific working process of the steel structure beam hoisting and leveling device described in this embodiment is as follows:

[0038] The two I-beams 9 are installed as a whole, with the third connecting plate 8 and support 4 fixed in place. Bolts 6 are passed through the bolt holes of the second connecting plate 7. The second connecting plate 7 is temporarily placed on the flange of the upper flange of the third connecting plate 8 and the I-beam 9. The position of the second connecting plate 7 is adjusted so that the bolt holes on the second connecting plate 7 align with the bolt holes of the first connecting plate 5. The first connecting plate 5 is fixed to the second connecting plate 7 by bolts 6. Through the pressing action of the jack, the force is transmitted to the third connecting plate, and in conjunction with the limiting action of the second connecting plate, the two I-beams with different heights are leveled by the pressing action of the flat plate. This device enables the leveling of I-beams under different operating conditions. It standardizes and regulates steel structure installation operations, improves work quality, reduces additional costs, is simple to operate, can be reused, avoids material waste, and achieves significant economic and environmental benefits.
