The top of the guide rail is provided with a plurality of sliding mechanisms for supporting the roof cover. A tension beam is fixed between two mounting seats in a connecting mechanism between two adjacent sliding mechanisms. A penetrating bidirectional threaded rod is rotatably connected between the two sides of the tension beam.

Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and relates to a large-span special-shaped steel structure roof and a construction method thereof. Background Art

[0002] Due to its easy molding and excellent mechanical properties, steel structures are widely used as an important structural form in building structures. This is especially true for various structural roofs. To create complex architectural artistic shapes, steel structures are often used in the roof structures of various large and complex public buildings. In actual engineering applications, the construction methods of steel roof structures can be roughly divided into high-altitude loose assembly, segmented installation, overall lifting, and overall sliding. The corresponding method is adopted according to the actual project conditions.

[0003] The overall sliding roof method is primarily used when construction sites restrict the installation of loose components or require temporary supports. Previously, the overall or sliding installation of truss structures was primarily used for the main roof structure. While the technology is relatively mature, it lacks flexibility in providing local support for irregularly shaped roofs. During the overall sliding construction of the roof, the lack of support in certain locations can easily cause deformation of the roof, compromising construction quality. To address these issues, the present invention proposes a large-span, irregularly shaped steel roof structure and its construction method. Summary of the Invention

[0004] In view of this, the present invention provides a large-span special-shaped steel structure roof and its construction method in order to solve the problem that the flexibility of the local support of the special-shaped roof body is poor, and when the roof structure body is slid as a whole, the deformation is large due to the lack of support at local positions, which affects the subsequent construction quality.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] A large-span special-shaped steel structure roof, comprising:

[0007] A translation system is installed between the lower steel structure and the roof cover. The translation system includes a guide rail fixedly connected to the top of the lower steel structure. The top of the guide rail is provided with multiple sliding mechanisms for supporting the roof cover. A connecting mechanism is provided between two adjacent sliding mechanisms.

[0008] The connecting mechanism includes two mounting seats, a tension beam is fixed between the two mounting seats by a pin shaft, a bidirectional threaded rod is rotatably connected between the two sides of the tension beam, the circumferential thread of the bidirectional threaded rod is connected to two symmetrically arranged second sliding seats, the top of the second sliding seat slides through the top of the tension beam, the tops of the two second sliding seats are rotatably connected to a push rod, and the tops of the two push rods are rotatably connected to the same support plate;

[0009] A hydraulic drive mechanism is provided on the guide rail to drive the roof cover to move.

[0010] Furthermore, the sliding mechanism includes a first sliding seat that slides on the top of the guide rail, both sides of the bottom of the first sliding seat are rotatably connected to a penetrating mounting shaft, the circumference of the mounting shaft is fixedly connected to a sliding roller, the surface of the first sliding seat is fixedly connected to a base plate, the surface of the base plate is fixedly connected to a plurality of one-way threaded columns, a top plate is slidably connected between the plurality of one-way threaded columns, the circumference of the one-way threaded columns is threadedly connected to a nut for supporting the top plate, the surface of the top plate is fixedly connected to a support frame, the two mounting seats are respectively fixedly connected to the surfaces of two adjacent base plates, and the surface of the base plate is provided with an anti-slip component for preventing the vehicle from slipping.

[0011] Furthermore, the anti-skid assembly includes a sliding frame and two brake wheels. The sliding frame slides through the base plate and the top of the first sliding seat. The bottom of the sliding frame is fixedly connected to two chucks. The two brake wheels are respectively fixedly connected to the circumference of two of the mounting shafts. The two chucks are used in conjunction with the two brake wheels respectively. The top of the sliding frame is threadedly connected to a first threaded rod that passes through it, and the bottom of the first threaded rod is threadedly connected to the base plate.

[0012] Furthermore, gaskets are fixedly connected to the tops of the support frame and the support plate.

[0013] Furthermore, the hydraulic drive mechanism includes a fixed seat, which is arranged on the surface of the guide rail. One side of the fixed seat is rotatably connected to a hydraulic cylinder, one end of the hydraulic cylinder piston rod is rotatably connected to one side of one of the mounting seats, and both sides of the fixed seat are threadedly connected to a second threaded rod passing through, and the other ends of the two second threaded rods are rotatably connected to a clamping plate for clamping the guide rail.

[0014] Furthermore, penetrating guide rods are inserted into both sides of the fixing seat, and the guide rods are respectively fixed to adjacent clamping plates.

[0015] Furthermore, the push rod includes two internal threaded sleeves and a bidirectional threaded column. The two internal threaded sleeves are rotatably connected to the second sliding seat and the support plate respectively, and the bidirectional threaded column is threadedly connected between the two internal threaded sleeves.

[0016] The present invention also proposes a construction method for a large-span special-shaped steel structure roof, comprising the following steps:

[0017] S1: Install the assembled first sliding seat and base plate on the guide rail, then rotate the first threaded rod to push the sliding frame downward, and the sliding frame drives the chuck downward, thereby locking the brake wheel and preventing the first sliding seat from moving;

[0018] S2: Select the support frame according to the height of the roof cover, and then fix it on the top of the top plate. If there is a height error, turn the nut on the one-way threaded column to complete the adjustment of the top plate, and fix the gasket for supporting the roof cover on the top of the support frame;

[0019] S3: Assemble the roof cover. After the roof cover at a certain position is assembled, the contact between the chuck and the brake wheel is released, and the hydraulic cylinder is started. The hydraulic cylinder is used to push the sliding mechanism to move horizontally. After the movement is completed, the chuck is continued to contact the brake wheel, and then the second threaded rod on the fixing seat is loosened, and the hydraulic cylinder is reset. After the fixing seat is moved to the new position, the second threaded rod is locked to complete the fixing of the fixing seat.

[0020] S4: Similarly, continue to install, fix and support the rear roof cover, and install a tension beam between the two adjacent base plates. Then rotate the bidirectional threaded rod on the tension beam. The bidirectional threaded rod drives the two second sliding seats to rotate. The second sliding seats drive the two top rods to lift the support plate. The support plate is used to support the middle part of the roof cover to maintain the stability of the roof cover movement.

[0021] The beneficial effects of the present invention are:

[0022] 1. The large-span, special-shaped steel structure roof disclosed in the present invention has a configuration in which a liftable support plate is installed on the tension beam. By rotating the bidirectional threaded rod, the second sliding seat can be driven to move, and the support plate can be lifted up by the push rod. The middle part of the roof cover is supported by the support plate, thereby improving the stability of the roof cover during translation and preventing the problem of deformation due to large spans.

[0023] 2. The large-span, special-shaped steel structure roof disclosed in the present invention uses a chuck and a brake wheel in combination. While translating the hydraulic drive mechanism, the first threaded rod is rotated. The first threaded rod drives the chuck to move through the sliding frame, thereby making the chuck contact with the brake wheel to prevent the first sliding seat from sliding, thereby improving the safety of the system.

[0024] 3. The large-span, special-shaped steel structure roof disclosed in the present invention can be adjusted by the height of the top plate. When there is a distance difference between the height of the support frame and the roof cover, the nut is rotated to change the position of the top plate, which facilitates the adjustment of the height of the support frame and improves the flexibility of the system.

[0025] 4. The large-span, special-shaped steel structure roof disclosed in the present invention supports the middle part of the roof cover through a support plate, thereby improving the stability of the roof cover during translation and preventing the problem of large span deformation. At the same time, the chuck is in contact with the brake wheel to prevent the first sliding seat from sliding, thereby improving the safety of the system. It can also change the position of the top plate, facilitate the adjustment of the height of the support frame, and improve the flexibility of the system.

The objects and other advantages of the present invention may be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] like Figures 1 to 5 The large-span, special-shaped steel structure roof shown includes a set of translation systems 3 installed between the lower steel structure 1 and the roof cover 2. The translation systems 3 are selected according to the construction conditions, and at least two translation systems 3 are provided. In this embodiment, there are two translation systems 3. The translation system 3 includes a guide rail 4, which is fixedly connected to the top of the lower steel structure 1. The top of the guide rail 4 is provided with multiple sliding mechanisms 5 for supporting the roof cover 2, and a connecting mechanism 7 is provided between two adjacent sliding mechanisms 5.

[0039] Reference Figure 3The sliding mechanism 5 includes a first sliding seat 10 that slides on the top of the guide rail 4. Both sides of the bottom of the first sliding seat 10 are rotatably connected to a penetrating mounting shaft 15. The circumference of the mounting shaft 15 is fixedly connected to a sliding roller 16. The surface of the first sliding seat 10 is fixedly connected to a bottom plate 11. The surface of the bottom plate 11 is fixedly connected to a plurality of one-way threaded columns 12. A top plate 13 is slidably connected between the plurality of one-way threaded columns 12. The circumference of the one-way threaded columns 12 is threadedly connected to a nut 14 for supporting the top plate 13. The surface of the top plate 13 is fixedly connected to a support frame 8. Two mounting seats 26 are respectively fixedly connected to the surfaces of two adjacent bottom plates 11. The support frame 8 is selected according to the height of the roof cover 2. The support frame 8 can be flexibly welded and used according to the on-site construction conditions, and then fixed to the top of the top plate 13. If there is a height error, the nut 14 on the one-way threaded column 12 is rotated to complete the adjustment of the top plate 13. The surface of the bottom plate 11 is provided with an anti-slip component to prevent the vehicle from slipping.

[0040] Reference Figure 3 The anti-slip assembly includes a sliding frame 19 and two brake wheels 17. The sliding frame 19 slides through the bottom plate 11 and the top of the first sliding seat 10. The bottom of the sliding frame 19 is fixedly connected to two chucks 20. The two brake wheels 17 are respectively fixedly connected to the circumference of two mounting shafts 15. The two chucks 20 are used in conjunction with the two brake wheels 17. The top of the sliding frame 19 is threadedly connected with a first threaded rod 18 that passes through it. The bottom of the first threaded rod 18 is threadedly connected to the bottom plate 11. Rotate the first threaded rod 18 and use the first threaded rod 18 to push the sliding frame 19 to move downward. The sliding frame 19 drives the chuck 20 to move downward, thereby jamming the brake wheel 17 to prevent the first sliding seat 10 from moving. The top of the support frame 8 is fixedly connected to the gasket 9.

[0041] The connecting mechanism 7 includes two mounting seats 26. A tension beam 27 is fixed between the two mounting seats 26 via a pin. A bidirectional threaded rod 28 is rotatably connected to the two sides of the tension beam 27. The bidirectional threaded rod 28 is circumferentially threadedly connected to two symmetrically arranged second sliding seats 29. The top of the second sliding seat 29 slides through the top of the tension beam 27. A top rod 30 is rotatably connected to the top of each second sliding seat 29. The tops of the two top rods 30 are rotatably connected to the same support plate 31. The tension beam 27 is installed between two adjacent base plates 11. The bidirectional threaded rod 28 is rotated, which drives the two second sliding seats 29 to rotate. The support plate 31 then supports the middle portion of the roof cover 2, maintaining the stability of the roof cover 2 during movement. The top of the support plate 31 is fixedly connected to the gasket 9.

[0042] The hydraulic drive mechanism 6 is provided on the guide rail 4 for driving the roof cover 2 to move.

[0043] Reference Figure 4The hydraulic drive mechanism 6 includes a fixed seat 21, which is arranged on the surface of the guide rail 4. One side of the fixed seat 21 is rotatably connected to a hydraulic cylinder 22. One end of the piston rod on the hydraulic cylinder 22 is rotatably connected to one side of one of the mounting seats 26. Both sides of the fixed seat 21 are threadedly connected with a penetrating second threaded rod 25. The other ends of the two second threaded rods 25 are rotatably connected with a clamping plate 24 for clamping the guide rail 4. Start the hydraulic cylinder 22 and use the hydraulic cylinder 22 to push the sliding mechanism 5 to move horizontally. After loosening the clamping plate 24, the hydraulic cylinder 22 can be reset to facilitate reuse. Both sides of the fixed seat 21 are plugged with a penetrating guide rod 23, which is respectively fixed to the adjacent clamping plates 24.

[0044] Reference Figure 5 The push rod 30 includes two internal threaded sleeves 32 and a bidirectional threaded column 33. The two internal threaded sleeves 32 are rotatably connected to the second sliding seat 29 and the support plate 31 respectively. The bidirectional threaded column 33 is threadedly connected between the two internal threaded sleeves 32. Rotating the bidirectional threaded column 33 can also adjust the length of the push rod 30, thereby improving the flexibility of the system.

[0045] The present invention also proposes a construction method for a large-span special-shaped steel structure roof, comprising the following steps:

[0046] S1: Install the assembled first sliding seat 10 and base plate 11 on the guide rail 4, then rotate the first threaded rod 18, and use the first threaded rod 18 to push the sliding frame 19 to move downward. The sliding frame 19 drives the chuck 20 to move downward, thereby locking the brake wheel 17 and preventing the first sliding seat 10 from moving;

[0047] S2: Select the support frame 8 according to the height of the roof cover 2, and then fix it on the top of the top plate 13. If there is a height error, turn the nut 14 on the one-way threaded column 12 to complete the adjustment of the top plate 13, and fix the gasket 9 for supporting the roof cover 2 on the top of the support frame 8;

[0048] S3: Assemble the roof cover 2. After the roof cover 2 at one position is assembled, release the contact between the chuck 20 and the brake wheel 17, start the hydraulic cylinder 22, and use the hydraulic cylinder 22 to push the sliding mechanism 5 to move horizontally. After the movement is completed, continue to use the chuck 20 to contact the brake wheel 17, then loosen the second threaded rod 25 on the fixing seat 21, reset the hydraulic cylinder 22, and then lock the second threaded rod 25 after the fixing seat 21 moves to the new position to complete the fixing of the fixing seat 21.

[0049] S4: Similarly, continue to install, fix and support the rear roof cover 2, and install the tension beam 27 between the two adjacent base plates 11, then rotate the bidirectional threaded rod 28 on the tension beam 27, the bidirectional threaded rod 28 drives the two second sliding seats 29 to rotate, the second sliding seats 29 drive the two top rods 30 to lift the support plate 31, and use the support plate 31 to support the middle part of the roof cover 2 to maintain the stability of the movement of the roof cover 2.
