Figures 1 to 6 , this application provides a prefabricated heavy steel frame factory building structure, please refer to Figure 1 , Figure 4 and Figure 6 , comprising a roof truss 1 installed on a foundation; Four symmetrically distributed roof beams 2 are installed at the top of the roof truss 1 through high-strength bolts, and a connecting beam 21 is installed between every two symmetrically arranged roof beams 2 through high-strength bolts. The bottom ends of the two connecting beams 21 and the top of the roof truss 1 are installed with a supporting beam 22 through high-strength bolts; The inner walls of every two roof beams 2 on the same side are connected with a main roof board 3 through high-strength bolts, and every two roof beams 2 on the same side are slidably connected with a secondary roof board assembly 31. A driving mechanism 4 is installed at the top of the roof truss 1 to drive the secondary roof board assembly 31 to slide on the roof beam 2; The tops of the two connecting beams 21 are commonly connected to a fixing seat 5, and the top of the fixing seat 5 is rotatably connected to two symmetrically distributed baffles 32. A crossbeam 51 is connected between the two supporting beams 22 via high-strength bolts, and a movable mechanism 6 for driving the baffles 32 to rotate is arranged on the crossbeam 51.

[0028] Specifically, after the roof beam 2, the connecting beam 21 and the supporting beam 22 are assembled and installed on the roof truss 1, the driving mechanism 4 drives the secondary roof panel assembly 31 to slide on the roof beam 2, so that the roof can be opened. The movable mechanism 6 will be affected by the driving mechanism 4, and then drive the two baffles 32 to flip, further expanding the upper end of the opened roof. By opening the top of the factory building, in summer, natural wind can be used to achieve indoor ventilation and heat dissipation, improve indoor air quality, and reduce temperature and humidity. In winter when there is no snow, natural light can be maximized for lighting to improve lighting efficiency. In winter when there is snow accumulation, the driving mechanism 4 and the movable mechanism 6 drive the secondary roof panel assembly 31 to move back and forth over a short distance and the baffle 32 to flip back and forth within a certain range, so as to remove the snow on the upper surface of the factory roof, so that the structure will not be damaged or even collapsed due to the heavy pressure of the snow, thereby greatly improving the use effect of the factory building.

[0029] Please refer to Figure 1 and Figure 2 , the roof truss 1 includes a column 11, a main beam 12 and a secondary beam 13; Four columns 11 are installed on the foundation, and the tops of every two columns 11 are connected to the main beam 12 through high-strength bolts, and the secondary beam 13 is connected between the two main beams 12 through high-strength bolts.

Meanwhile, shock-absorbing gaskets may be installed on the fitting surfaces between the reinforcing ribs and the columns 11, main beams 12 and secondary beams 13 to reduce vibration and improve the stability of the roof truss 1.

[0031] Please refer to Figure 1 and Figure 4 , the driving mechanism 4 includes a fixed block 41, a reverse screw rod 42, a slide rod 43, a servo motor 44 and a lifting column 45; Two fixed blocks 41 are symmetrically connected to the top of each main beam 12, wherein a reverse screw rod 42 is rotatably connected between the two fixed blocks 41, and the outer wall of the reverse screw rod 42 passes through the interior of the support beam 22; a sliding rod 43 is connected between the other two fixed blocks 41, and the sliding rod 43 passes through the interior of the support beam 22; a servo motor 44 is installed on the outer wall of any fixed block 41, and the output end of the servo motor 44 is socketed with any end of the reverse screw rod 42; two lifting columns 45 are threadedly connected to the reverse screw rod 42, and the top of each lifting column 45 is connected to the lower end of the secondary roof panel assembly 31 by a high-strength bolt.

[0032] Specifically, the servo motor 44 drives the reverse screw rod 42 to rotate, so that the reverse screw rod 42 drives the lifting column 45 to move, and then the lifting column 45 drives the top sub-roof panel assembly 31 to slide on the roof beam 2. When the sub-roof panel assembly 31 moves, it will drive another lifting column 45 to slide on the sliding rod 43, thereby maintaining the stability of the sub-roof panel assembly 31 during movement.

[0033] Please refer to Figure 5 , the lifting column 45 includes a positioning tube 451, a movable tube 452, a supporting tube 453 and a spring 454; Two positioning tubes 451 are symmetrically connected to the lower end of each sub-roof panel assembly 31, and movable tubes 452 are connected inside the two positioning tubes 451 through high-strength bolts. The outer wall of each movable tube 452 is slidably connected to a support tube 453, and the lower end of each support tube 453 is threadedly connected to the outer wall of the reverse screw rod 42. The bottom end of each movable tube 452 is connected to a spring 454, and the bottom end of each spring 454 is connected to the bottom end of the inner wall of the support tube 453.

[0034] Specifically, the sub-roof panel assembly 31 is in an inclined sliding state on the roof beam 2, thereby driving the positioning tube 451 and the movable tube 452 to slide inside the support tube 453, thereby causing the spring 454 to produce elastic deformation until the sub-roof panel assembly 31 stops and the spring 454 remains stable.

[0035] Please refer to Figure 5 Two slide grooves 4521 are provided inside each movable tube 452 , and a slider 4522 is slidably connected inside each slide groove 4521 , and each slider 4522 is connected to the inner wall of the support tube 453 .

[0036] Specifically, when the movable tube 452 slides inside the support tube 453, the slider 4522 will slide inside the slide groove 4521, thereby preventing the movable tube 452 from escaping from the support tube 453, thereby playing a limiting role and further maintaining the stability of the movable tube 452 when it is raised and lowered inside the support tube 453.

[0037] Please refer to Figure 4 , the secondary roof panel assembly 31 includes a movable steel panel 311 and a secondary roof panel 312; The top end of each positioning tube 451 is connected to the bottom end of the movable steel plate 311 , and a secondary roof plate 312 is commonly connected between the two movable steel plates 311 .

[0038] Specifically, when the secondary roof panel assembly 31 is displaced, the movable steel plate 311 will slide on the roof beam 2, and the movable steel plate 311 will drive the secondary roof panel 312 to move synchronously. When it snows in winter, the secondary roof panel 312 will push the snow on the main roof panel 3 to move, thereby effectively reducing the accumulation of snow on the factory roof.

[0039] Please refer to Figure 4 and Figure 5 A slot 3111 is provided inside each movable steel plate 311 , and each slot 3111 is slidably connected to the outer wall of the main roof plate 3 .

[0040] Specifically, when the movable steel plate 311 is displaced, under the action of the clamping groove 3111 , the movable steel plate 311 can be moved in contact with the outer wall of the main roof plate 3 .

[0041] Please refer to Figure 1 and Figure 6 , the movable mechanism 6 includes a connecting plate 61, a slide plate 62, a connecting rod 63, a screw rod 64 and a linkage assembly 65; Two connecting plates 61 are connected to the top of the cross beam 51, and the tops of the two connecting plates 61 are connected to the bottom of the fixed seat 5. The outer walls of the two connecting plates 61 are slidably connected with a slide plate 62. The slide plate 62 is rotatably connected with four connecting rods 63 symmetrically arranged in pairs. The top of each connecting rod 63 is rotatably connected to the bottom end of the baffle 32. A screw rod 64 is rotatably connected inside the cross beam 51, and the top of the screw rod 64 is rotatably connected to the bottom end of the fixed seat 5. The inner wall of the slide plate 62 is connected to the outer wall of the screw rod 64 through a thread, and a linkage component 65 for driving the screw rod 64 to rotate is arranged inside the cross beam 51.

[0042] Specifically, the slide plate 62 is driven to move by rotating the screw rod 64. The slide plate 62 will slide on the connecting plate 61 while moving, so as to prevent the slide plate 62 from rotating when being raised or lowered, thereby playing a limiting role. By raising or lowering the slide plate 62, a plurality of connecting rods 63 are driven to rise or fall, so that the connecting rods 63 drive the baffle plate 32 connected to the top to rotate, thereby further expanding the space generated after the displacement of the sub-roof panel assembly 31.

[0043] Please refer to Figure 6 , the linkage assembly 65 includes a rotating rod 651, a first bevel gear 652, a second bevel gear 653 and a third bevel gear 654; A rotating rod 651 is rotatably connected inside the crossbeam 51, and both ends of the rotating rod 651 are connected to a first bevel gear 652. The outer walls of the two first bevel gears 652 are respectively meshed with a second bevel gear 653 and a third bevel gear 654. The second bevel gear 653 is connected to the outer wall of the reverse screw rod 42, and the third bevel gear 654 is connected to the outer wall of the screw rod 64.

[0044] Specifically, when the reverse screw 42 rotates, the second bevel gear 653 is driven to rotate, and the second bevel gear 653 drives the first bevel gear 652 to rotate, and then drives the rotating rod 651 to rotate, and the rotating rod 651 drives the first bevel gear 652 at the other end to rotate, and then drives the third bevel gear 654 to rotate, and the third bevel gear 654 drives the screw 64 to rotate.

[0045] On the other hand, the embodiment of the present application also provides a construction method of an assembled heavy steel frame factory building structure according to the above, comprising the following steps: S1: measuring and laying out, determining the installation positions of the columns 11, the main beams 12 and the secondary beams 13 on the foundation, and installing them in sequence to form the roof truss 1; S2: Determine the installation positions of the roof beam 2, the connecting beam 21, and the supporting beam 22 on the roof truss 1, and install them in sequence to form the roof part; S3: Install the main roof panel 3, the secondary roof panel assembly 31 and the baffle 32 on the roof to complete the installation of the outer surface of the roof; S4: driving the secondary roof panel assembly 31 to slide on the roof beam 2 through the driving mechanism 4, thereby opening the roof; S5: When the driving mechanism 4 moves, the movable mechanism 6 is driven to operate synchronously, so that the two baffles 32 are turned over to expand the opening area of ​​the roof.

[0046] Working principle: The connection between the column 11, the main beam 12 and the secondary beam 13 can be provided with reinforcing ribs for auxiliary positioning and installation. At the same time, anti-vibration pads can be installed on the contact surface between the reinforcing ribs and the column 11, the main beam 12 and the secondary beam 13, so as to reduce vibration and improve the stability of the roof truss 1. The roof beam 2, the connecting beam 21 and the supporting beam 22 are assembled and installed behind the roof truss 1; The servo motor 44 drives the reverse screw rod 42 to rotate, so that the reverse screw rod 42 drives the lifting column 45 to move, and then the lifting column 45 drives the top sub-roof panel assembly 31 to slide on the roof beam 2. When the sub-roof panel assembly 31 moves, it will drive another lifting column 45 to slide on the slide bar 43, so as to maintain the stability of the sub-roof panel assembly 31 when moving. The sub-roof panel assembly 31 is in a tilted sliding state on the roof beam 2, and then drives the positioning tube 451 and the movable tube 452 to slide inside the support tube 453, so that the spring 454 produces elastic deformation until the sub-roof panel assembly 31 is stationary, and the spring 454 remains stable. When the movable tube 452 slides inside the support tube 453, the slider 4522 slides inside the slide groove 4521, so as to prevent the movable tube 452 from being separated from the support tube 453, thereby playing a limiting role, and further maintaining the stability of the movable tube 452 when it is lifted and lowered inside the support tube 453, so as to open the roof. When the secondary roof panel assembly 31 is displaced, the movable steel plate 311 slides on the roof beam 2, and the movable steel plate 311 drives the secondary roof panel 312 to move synchronously. When there is snow in winter, the secondary roof panel 312 pushes the snow on the main roof panel 3 to move, thereby effectively reducing the accumulation of snow on the roof of the factory building; When the reverse screw rod 42 rotates, the second bevel gear 653 is driven to rotate, so that the second bevel gear 653 drives the first bevel gear 652 to rotate, and then drives the rotating rod 651 to rotate, so that the rotating rod 651 drives the first bevel gear 652 at the other end to rotate, and then drives the second bevel gear 654 to rotate, so that the second bevel gear 654 drives the screw rod 64 to rotate, and the rotation of the screw rod 64 drives the slide plate 62 to move. While the slide plate 62 moves, it will slide on the connecting plate 61 to prevent the slide plate 62 from rotating when it is lifted, thereby playing a limiting role. By lifting and lowering the slide 62, multiple connecting rods 63 are driven to lift and lower, so that the connecting rod 63 drives the top to rotate the connected The rotation of the baffle 32 can further expand the space generated by the displacement of the sub-roof panel assembly 31. By opening the top of the factory building, in summer, natural wind can be used to achieve indoor ventilation and heat dissipation, improve indoor air quality, and reduce temperature and humidity. When there is no snow in winter, natural light can be maximized for lighting to improve lighting efficiency. When snow accumulates in winter, the driving mechanism 4 and the movable mechanism 6 drive the sub-roof panel assembly 31 to move back and forth over a short distance and the baffle 32 to flip back and forth within a certain range, which can remove the snow on the upper surface of the factory roof, so that the structure will not be damaged or even collapsed due to the heavy pressure of the snow, thereby greatly improving the use effect of the factory building.

[0047] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
