[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] See also Figures 1-10 , a method for the overall lifting and installation of steel structure diagonal ceiling keels, which adopts the overall lifting hoisting technology, is suitable for most steel keel decoration projects, ensuring construction safety and construction period, saving construction costs and ensuring construction safety. The specific construction steps are as follows:

[0045] S1. Survey and lay out the lines, combine existing control points, arrange the corner wire network, and establish the control network for the construction of steel structure diagonal bracing ceiling keels;

[0046] S2. Deepening of the structure of steel structure ceiling keel 6: Using BIM technology to coordinate the design of steel structure ceiling keel 6 to carry out the structural deepening work of steel structure ceiling keel 6;

[0047] The structural detailing of the steel ceiling keel 6 is accomplished through 3D visualization, material parameter extraction, simulated layout, virtual prototypes, drawing, and 3D presentation. Key details include structural detailing, collision detection, and installation method detailing. BIM modeling integrates and analyzes the steel ceiling keel 6 with the building's main structure and electromechanical pipeline models to detect collisions and conflicting areas, enabling early design optimization.

[0048] S3. Design and manufacture a lifting device based on computer theoretical data as an important transportation device for the steel structure ceiling keel 6 material;

[0049] The hoisting device is an electric slide rail hoisting device. Integrated finite element modeling was used to analyze the design strength and stability of the hoisting device to ensure construction quality and safety. Three-dimensional solid element modeling was performed for the structural beams and slabs, hoisting device components, and hoisting loads. The model was defined by assigning different real constants, cross-section types, and sizes. The material model used the multilinear isotropic hardening model (MISO). The hoisting load was taken as the most unfavorable weight, and the design shear stress at the load nodes of the hoisting device and the deformation and displacement of slide rail 1 were simulated and verified.

[0050] S4. Installation of electric slide rail lifting device;

[0051] S5. Assemble the steel structure ceiling keel 6 on the ground according to the construction drawings;

[0052] S6. Lift the steel ceiling keel 6 as a whole. Weld diagonal braces 7 at the four corners of the ceiling for initial installation and fixation. Install four diagonal braces 7 above the steel ceiling keel 6. Before using the lifting device for overall lifting, conduct a trial lift to confirm the stability and security of the lifting equipment. The trial lift height should not exceed 0.5m. Control the power trolley 3 to lift to the installation location. Use expansion bolts to secure the diagonal braces 7 to the embedded bracket 2 10. Finally, complete the installation of the steel ceiling keel 6 and the embedded bracket 1 9.

[0053] The steel structure ceiling keel 6 is lifted as a whole. After the construction is completed, measuring instruments such as total stations and levels are required to detect the distance from the ground of each lifting point, calculate the relative height difference of each lifting point, and adjust the height of each lifting point to make the steel structure ceiling keel 6 reach the designed posture; after ensuring that all design parameters are correct, the steel structure ceiling keel 6 is lifted as a whole using a lifting device.

[0054] See also Figure 2-Figure 7 The electric slide rail lifting device includes a slide rail 1 and a steel structure ceiling keel 6. A fixing component 2 is provided on the top of the slide rail 1, and the fixing component 2 is fixed to the ceiling by screws or the like. A power trolley 3 is slidably connected to the bottom of the slide rail 1, a lifting drive component 4 is installed at the bottom of the power trolley 3, a suspension component 5 is fixedly installed at the bottom of the lifting drive component 4, and two groups of hooks 510 are provided at the bottom of the suspension component 5. The four ends of the steel structure ceiling keel 6 are fixedly installed with diagonal braces 7. Four lifting points are provided on the top of the steel structure ceiling keel 6, and steel cables 8 are fixedly installed on the two lifting points distributed in the front and back. The middle parts of the two groups of steel cables 8 are respectively hung on the two groups of hooks 510. Four groups of pre-embedded brackets 1 9 and four groups of pre-embedded brackets 2 10 are fixedly installed on the wall. The four groups of pre-embedded brackets 1 9 are used to support the lower sides of the four ends of the steel structure ceiling keel 6, and the four groups of pre-embedded brackets 2 10 are used to support the lower sides of the four diagonal braces 7. The end of the steel structure ceiling keel 6 is fixed to the embedded bracket 1 9 by bolts, and the diagonal brace 7 is fixed to the embedded bracket 2 10.

[0055] The slide rail 1 is an I-beam. The fixed assembly 2 includes a sleeve 201. The slide rail 1 is slidably connected to the interior of the sleeve 201. Multiple suspension rods 202 are equidistantly fixed to the top of the sleeve 201. Threaded holes are provided on both sides of the sleeve 201. The sleeve 201 is connected to limit bolts 203 through the threaded holes. The limit bolts 203 are attached to the surface of the slide rail 1. By sliding the slide rail 1 relative to the sleeve 201, a portion of the slide rail 1 is extended to the outside of the building. Afterwards, the construction materials are lifted upward and then slid toward the interior of the building, thereby transferring the construction materials from the outside to the inside of the building. The relative position of the slide rail 1 and the sleeve 201 is fixed by tightening the limit bolts 203. In addition, baffles 101 are welded to both ends of the slide rail 1 to prevent the slide rail 1 from detaching from the sleeve 201 when sliding relative to the sleeve 201. They also prevent the power trolley 3 from detaching from the slide rail 1 when moving along the slide rail 1.

[0056] The power trolley 3 includes a U-shaped plate 301, which is composed of two side plates and a bottom plate. U-shaped plate 301 is U-shaped. Mounting covers 302 are fixedly mounted on both sides of U-shaped plate 301, forming a receiving cavity between the mounting covers 302 and the side plates of U-shaped plate 301. Each mounting cover 302 is rotatably connected to two rotating shafts 303, which extend through the side plates of U-shaped plate 301 and into the interior of U-shaped plate 301. A wheel 304 is fixedly mounted on one end of the rotating shaft 303 located within U-shaped plate 301, and the wheel 304 rolls against the upper surface of the bottom end of the slide rail 1.

[0057] A sprocket 1 305 is fixedly mounted on the circumferential surface of the rotating shaft 1 303 located within the accommodating cavity. A motor 1 306 is fixedly mounted on the surface of the front mounting cover 302. A drive shaft 307 is fixedly mounted on the output end of the motor 1 306. The drive shaft 307 extends through and rotatably connects to the U-shaped plate 1 301 and the two sets of mounting covers 302. Two sets of sprockets 2 308 are fixedly mounted on the drive shaft 307. The two sets of sprockets 2 308 are located in the two accommodating cavities, respectively. Within the accommodating cavities, the two sets of sprockets 1 305 and sprockets 2 308 are connected by a chain belt 309. The rotation of the drive shaft 307 by the motor 1 306 drives the two sets of sprockets 2 308 to rotate synchronously. The transmission function of the sprockets 2 308, the chain belt 309, and the sprocket 1 305 drives the four sets of wheels 304 to rotate synchronously. As a result, the four sets of wheels 304 roll on the slide rail 1, allowing the power cart 3 to travel on the slide rail 1.

[0058] The lifting drive 4 includes a second U-shaped plate 401 fixedly mounted at the bottom of the first U-shaped plate 301. A second motor 402 is fixedly mounted on the right side of the second U-shaped plate 401. A reel 403 is fixedly mounted on the output end of the second motor 402. The reel 403 is rotatably connected to the interior of the second U-shaped plate 401. A steel wire rope 404 is wound around the reel 403. A through hole 405 is formed through the bottom of the second U-shaped plate 401. The steel wire rope 404 passes through the through hole 405. The edges of the through hole 405 are provided with curved chamfers. The second motor 402 drives the reel 403 to rotate, reeling or releasing the steel wire rope 404, thereby driving the suspension assembly 5, the steel cable 8, and the steel structure ceiling keel 6 to rise and fall.

[0059] The suspension assembly 5 includes an arch plate 501, which is arched. L-shaped plates 502 are fixedly installed on the front and rear sides of the arch plate 501. Motor 3 503 is fixedly installed on the back of the rear L-shaped plate 502. A rotating shaft 2 504 is fixedly installed on the output end of motor 3 503. The rotating shaft 2 504 is rotatably connected to the two groups of L-shaped plates 502 and the arch plate 1 501; a turntable 505 is fixedly installed on the circumferential surface of the rotating shaft 2 504 located inside the arch plate 1 501, and a spherical groove 506 is arranged in an array on the circumferential surface of the turntable 505.

[0060] Rotating shaft 2 504 is located on the circumferential surface between L-shaped plate 502 and arch plate 1 501 and is rotatably connected to arch plate 2 507. The top of arch plate 2 507 is fixedly mounted on the bottom end of wire rope 404. A suspension rope 508 is attached to the upper surface of turntable 505. Multiple steel balls 509 are fixed to the surface of suspension rope 508 at equal intervals. The steel balls 509 are embedded in spherical grooves 506. Two sets of hooks 510 are fixedly mounted on each end of suspension rope 508. Due to the difficulty in ensuring the equal length of the two steel cables 8 during actual operation, the steel structure ceiling keel 6 is prone to tilting during installation. Motor 3 503 drives rotating shaft 2 504 and turntable 505 to rotate, driving the suspension rope 508 to move, thereby adjusting the height difference between the two sets of hooks 510, thereby maintaining the steel structure ceiling keel 6 horizontally.

[0061] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
