DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0025] See also Figure 1-Figure 4One embodiment of the present invention is: a steel structure ceiling structure and an installation method thereof, comprising a keel 1, a sling 2 is fixedly installed on the top of the keel 1, a connecting piece 3 is rotatably installed on the surface of the keel 1, a rotating groove 49 is opened on the surface of the keel 1, a positioning hole 7 is opened on the surface of the keel 1, a positioning groove 8 is opened on the surface of the connecting piece 3, and a stabilizing device is arranged inside the connecting piece 3; The stabilizing device includes: a rotating shaft 41, a rotating plate 47 and a locking plate 48. The rotating shaft 41 is fixedly mounted on the surface of the connecting member 3, and the rotating shaft 41 is rotatably mounted on the inner wall of the rotating groove 49. The rotating plate 47 is fixedly mounted on the circumferential surface of the rotating shaft 41, and the locking plate 48 is fixedly mounted on the inner wall of the rotating groove 49, so that the connecting member 3 cannot be rotated excessively upward or downward, thereby improving the applicability of the device.

[0026] The stabilizing device also includes: a hollow tube 42, a piston 43, a transmission rod 44, a slider 45 and a protrusion 46. The hollow tube 42 is fixedly mounted on the circumferential surface of the rotating shaft 41, the piston 43 is slidably mounted on the inner wall of the hollow tube 42, a flow hole 410 is opened on the surface of the piston 43, the transmission rod 44 passes through and is slidably mounted on the outer wall of the hollow tube 42, one end of the transmission rod 44 is fixedly mounted on the surface of the piston 43, the slider 45 is fixedly mounted on the other end of the transmission rod 44, the protrusion 46 is fixedly mounted on the inner wall of the rotating groove 49, and the slider 45 is slidably mounted on the surface of the rotating groove 49 and the protrusion 46, so that the adjustment of the connecting member 3 can only be carried out slowly, and the workers can more accurately confirm the required adjustment angle when adjusting the position, further improving the work efficiency.

[0027] A non-Newtonian fluid is disposed inside the hollow tube 42 , and the rotating plate 47 contacts the positioning plate 48 . The non-Newtonian fluid solidifies instantly when subjected to a rapid impact, so that the non-Newtonian fluid restricts the piston 43 to move slowly inside the hollow tube 42 .

[0028] A method for installing a steel ceiling structure comprises the following steps: Step 1: Rotate the connecting member 3 to a desired angle. The connecting member 3 will be blocked by the blocking plate 48 during rotation, so that the connecting member 3 cannot be rotated excessively upward or downward, thereby improving the applicability of the device; Step 2: After the adjustment is completed, the load-bearing column is inserted into the connector 3. When the load-bearing column reaches the bottom, the L-shaped plate 55 will clamp the load-bearing column. After the worker docks the load-bearing beam, the load-bearing beam will be fixed for a short time, which is convenient for the worker to reinforce the load-bearing beam and further improves the work efficiency. Step 3: After inserting the load-bearing column, align the fixing rivet with the positioning hole 7 and rotate the fixing rivet to fix the load-bearing beam and the connecting piece. When the present embodiment is working, the connecting member 3 is adjusted according to different types of roofs, and the connecting member 3 is rotated. The rotation of the connecting member 3 drives the rotating shaft 41 to rotate, and the rotation of the rotating shaft 41 drives the rotating plate 47 to rotate. The rotating plate 47 contacts the blocking plate 48, and the blocking plate 48 blocks the rotation of the rotating plate 47, so that the connecting member 3 cannot rotate excessively upward or downward, thereby improving the applicability of the device. When the rotating shaft 41 rotates, the rotation of the rotating shaft 41 drives the hollow tube 42 to rotate, and the rotation of the hollow tube 42 drives the piston 43 to rotate, and the rotation of the piston 43 drives the transmission rod 44 to rotate, and the rotation of the transmission rod 44 drives the slider 45 to rotate, and the rotation of the slider 45 will rotate along As the outer wall of the rotating groove 49 rotates, the slider 45 rotates to contact the protrusion 46, and the protrusion 46 squeezes the slider 45. After being squeezed, the slider 45 drives the transmission rod 44 to move away from the protrusion 46. The movement of the protrusion 46 drives the piston 43 to move. When the piston 43 moves, due to the physical properties of the non-Newtonian fluid, the non-Newtonian fluid will solidify instantly when it is squeezed quickly, blocking the movement of the piston 43, so that the piston 43 can only move slowly inside the hollow tube 42, so that the adjustment of the connecting piece 3 can only be carried out slowly, so that the workers can more accurately confirm the required adjustment angle when adjusting the position, further improving the work efficiency.

[0030] The fixing device also includes: a reset rod 56, a trapezoidal block 57 and a fixed block 58. The fixed block 58 is fixedly installed on the top of the connecting member 3, the reset rod 56 is slidably installed on the inner wall of the fixed block 58, and the trapezoidal block 57 penetrates and is slidably installed on the inner and outer walls of the connecting member 3, so that workers can make adjustments again after the docking is completed, thereby improving the practicality of the device.

[0034] When this embodiment is working: after the angle adjustment is completed, the load-bearing beam that needs to be fixed is inserted into the interior of the connecting piece 3. The movement of the load-bearing beam will contact and push the transmission column 52 to move inward. The movement of the transmission column 52 will drive the long rod 53 to move. The movement of the long rod 53 will drive the connecting rod 54 to rotate. The rotation of the connecting rod 54 will drive the L-shaped plate 55 to rotate toward the bottom. The rotation of the L-shaped plate 55 will clamp the load-bearing beam, so that after the workers dock the load-bearing beam, the load-bearing beam will be fixed for a short time, which is convenient for the workers to reinforce the load-bearing beam, further improving the work efficiency. Manually push the reset rod 56, the movement of the reset rod 56 will drive the trapezoidal block 57 to move toward the bottom, and the movement of the trapezoidal block 57 will drive the long rod 53 to move in the direction of the transmission column 52. The movement of the long rod 53 will drive the connecting rod 54 to rotate. The rotation of the connecting rod 54 will drive the L-shaped plate 55 to rotate.

[0035] When the transmission column 52 moves, the transmission column 52 will contact the rotating plate 62, and the movement of the transmission column 52 will drive the rotating plate 62 to rotate. The rotation of the rotating plate 62 will drive the clamping block 63 to rotate, and the rotation of the clamping block 63 will contact the limit block 64, so that after the load-bearing column is connected, the clamping block 63 will limit the limit block 64, so that the connecting part 3 can no longer be adjusted in angle, which is convenient for workers to fix the weighing column by driving the fixing rivet into the positioning hole 7, preventing workers from needing to hold the weighing column while fixing it when working at high altitude, ensuring the safety of workers and further improving work efficiency.
