The gear 14 is meshed with the rack surface 31. A telescopic mechanism 12 is provided below the gear 14, and a lifting mechanism 22 is installed between the two telescopic mechanisms 12. The long strip 5 is driven by the gear 14 to continuously move toward the inside of the steel frame structure 1. The eight ceiling frames 7 can be aligned with the eight groups of steel frame structures 1 respectively, and in the process of the long strip 5 moving toward the inside of the steel frame structure 1, with the cooperation of the telescopic mechanism 12 and the lifting mechanism 22, the cross frame will bend with the middle rotating shaft as the center. At this time, a triangle is formed between the cross frame and the cross bar 11, and the middle part of the cross frame can be hung on the upper surface of the main support rod 4, which can achieve the effect of rapid construction, reduce manpower consumption, reduce construction difficulty, save construction time, and improve reusability.

[0025] A card slot 3 is provided on the surface of the side column 2, and a slide bar 28 is fixedly provided on the bottom of the long strip 5. The surface of the slide bar 28 is slidably engaged in the card slot 3 to ensure the tightness of the connection between the long strip 5 and the side column 2, and at the same time limit the position of the long strip 5 to avoid deviation in the installation of the long strip 5.

[0026] The side surface of the second support column 30 is provided with a positioning bolt, and the surface of the positioning bolt passes through the second support column 30 and the first support column 6. The second support column 30 and the first support column 6 are connected by the positioning bolt. The connection method is quick and simple, and enables the staff to quickly install the ceiling frame 7 above the long strip 5.

[0027] The ceiling frame 7 includes a cross frame, the middle part of the cross frame is connected by a rotating shaft, and slide grooves 8 are arranged at both ends of the bottom of the cross frame. The top of the first support column 6 is installed with a first frame 9 through a rotating shaft, and a slider is arranged on the top of the first frame 9 and installed in the slide groove 8. A cross bar 11 is arranged below the cross frame, and the two ends of the cross bar 11 are installed with a second frame 10 through a rotating shaft. A slider is arranged on the top of the second frame 10 and installed in the slide groove 8. The ceiling frame 7 is arranged in a straight line, which is convenient for the staff to carry the ceiling frame 7. Since the tops of the first frame 9 and the second frame 10 are both slidably installed in the slide groove 8, when the position of the cross bar 11 moves upward, with the cooperation of each rotating shaft, the cross frame will bend with the rotating shaft in the middle as the center. At this time, a triangle is formed between the cross frame and the cross bar 11. At the same time, with the cooperation of the gear 14 and the rack surface 31, the long strip 5 continuously moves to one side of the steel frame structure 1, and the middle part of the cross frame can be hung on the upper surface of the main support rod 4 to achieve a coordinated connection with the skeleton.

[0028] The telescopic mechanism 12 includes a rectangular frame 17, a cylindrical block 16 is fixedly installed at one end of the bottom of the gear 14, the interior of the rectangular frame 17 is sleeved on the surface of the cylindrical block 16, and a light rod 18 is fixedly installed on the outer surface of the rectangular frame 17. The surface of the light rod 18 passes through the side frame 13, and a protrusion 19 is installed on the other end of the light rod 18 by bolts. A baffle 20 is provided at the front end of the steel frame structure 1, and two protrusions 19 are respectively installed at both ends of the baffle 20. Since the rectangular frame 17 is movably sleeved on the surface of the cylindrical block 16, when the gear 14 drives the cylindrical block 16 to rotate, the rectangular frame 17 will follow the moving path of the cylindrical block 16 and be displaced. Under the rotation of the gear 14, the light rod 18 can make a linear reciprocating motion, and under the action of the protrusion 19, the baffle 20 will also reciprocate.

[0029] Guide posts 21 are disposed at both ends of the bottom of the baffle 20 , and the surfaces of the guide posts 21 penetrate through the side frame 13 , so as to further enhance the stability of the baffle 20 during movement.

[0030] The lifting mechanism 22 includes a bottom plate, a bottom tube 23 is arranged on the top of the bottom plate, a tension spring and a telescopic tube 24 are arranged inside the bottom tube 23, the top end of the tension spring is connected to the telescopic tube 24, the telescopic tube 24 is movably arranged inside the bottom tube 23, a top plate 27 is arranged on the top end of the telescopic tube 24, a second connecting rod 26 is installed at the bottom of the top plate 27 through a rotating shaft, a first connecting rod 25 is installed at the top of the bottom plate through a rotating shaft, the first connecting rod 25 and the second connecting rod 26 are connected through a rotating shaft, and the first connecting rod 25 and the second connecting rod 26 are located on one side of the bottom tube 23 and the telescopic tube 24, the baffle 20 is located at the front end of the first connecting rod 25 and the second connecting rod 26, and the baffle 20 is located at the front end of the first connecting rod 25 and the second connecting rod 26. When the telescopic cylinder 24 is used, it can be retracted to the inside of the bottom cylinder 23. At this time, the first connecting rod 25 and the second connecting rod 26 are in a bent state. When the baffle 20 moves to one side of the steel frame structure 1, the surface of the baffle 20 has an extrusion effect on the connection between the first connecting rod 25 and the second connecting rod 26, so that the first connecting rod 25 and the second connecting rod 26 gradually tend to an upright state, so that the telescopic cylinder 24 can move upward, and the top plate 27 can have an upward thrust on the cross bar 11 passing above the lifting mechanism 22. The cross bar 11 moves upward, and the bending operation of the cross frame can be realized. The middle part of the cross frame can be smoothly hung on the upper surface of the main support rod 4 to realize the construction of the steel structure skeleton.

[0031] A main support rod 4 is arranged above the steel frame structure 1, and an arc groove 29 is arranged on the top surface of the main support rod 4. The middle end of the cross frame is slidably installed in the arc groove 29. The main support rod 4 can support the folded cross frame so that the cross frame can be stably installed above the steel frame structure 1. At the same time, under the action of the arc groove 29, the stability of the connection between the ceiling frame 7 and the steel frame structure 1 is further guaranteed.

[0032] Working principle: First, under the cooperation of the gear 14 and the rack surface 31, the long strip 5 continuously moves to one side of the steel frame structure 1, and the eight ceiling frames 7 can be aligned with the eight groups of steel frame structures 1 respectively. In the process of the long strip 5 moving to the inner side of the steel frame structure 1, since the rectangular frame 17 is movably sleeved on the surface of the cylindrical block 16, when the gear 14 drives the cylindrical block 16 to rotate, the rectangular frame 17 will follow the moving path of the cylindrical block 16 and move. Under the rotation of the gear 14, the light rod 18 can make a linear reciprocating motion. Under the action of the protrusion 19, the baffle 20 will also reciprocate. Then, when the baffle 20 moves to the side away from the steel frame structure 1, under the action of the tension spring, the telescopic cylinder 24 can be retracted to the inside of the bottom cylinder 23. At this time, the first connecting rod 25 and the second connecting rod 26 are in a bent state. When the baffle 20 moves to one side of the steel frame structure 1, When the first connecting rod 25 and the second connecting rod 26 are connected, the surface of the baffle 20 has a squeezing effect on the connection between the first connecting rod 25 and the second connecting rod 26, so that the first connecting rod 25 and the second connecting rod 26 gradually tend to an upright state, so that the telescopic cylinder 24 can move upward, and the top plate 27 can have an upward thrust on the cross bar 11 passing above the lifting mechanism 22. With the cooperation of each rotating shaft, the cross frame will bend with the central rotating shaft as the center. At this time, a triangle is formed between the cross frame and the cross bar 11. At the same time, with the cooperation of the gear 14 and the rack surface 31, the long strip 5 continuously moves to one side of the steel frame structure 1, and the middle part of the cross frame can be hung on the upper surface of the main support rod 4. Finally, the eight ceiling frames 7 can be aligned with the eight groups of steel frame structures 1 respectively, completing the coordinated connection of the skeleton, which can achieve the effect of rapid construction, reduce manpower consumption, reduce the difficulty of construction, save construction time, and improve reusability.
