Description

Technical Field

[0002] Steel structure roof system building is a roof system that uses steel structure as the main component and is built on the top of the building. Its main features are light weight, high strength, corrosion resistance, good durability, and convenient construction. Steel structure roof system building can be applied to various types of buildings, such as factories, shopping malls, gymnasiums, exhibition centers, etc. Its use can greatly shorten the construction period, reduce construction costs, and improve the safety and reliability of buildings. In addition, steel structure roof system buildings can also achieve more unique architectural forms through innovations in design and structure, bringing more changes and beauty to the city's architectural landscape.

[0003] The roof structure of the stadium is an important architectural form that embodies the large-span steel structure. The stadium roof steel structure consists of a single-layer space special-shaped grid shell and a double-layer space special-shaped grid shell. It has a novel design and a complex structure. It is difficult to carry out the secondary in-depth design and construction. At present, the stadium roof system widely uses steel structure as the support system to reduce the deadweight of the upper structure and enhance the rigidity and overall stability of the roof grid. In the process of stadium roof construction, temporary support structures are often required to support the stadium roof, so as to facilitate its further construction.

[0004] In addition, due to the large coverage area and large installation span of the gymnasium steel structure roof, the span of the steel structure roof often exceeds 100m. The currently used support system only has line contact with the steel structure roof arch beam, and the support angle cannot be adjusted according to the arch beam position or arch shape, which leads to poor support stability and stress tolerance of the steel structure roof arch beam, affecting construction efficiency and construction progress.

A main slide groove 7 is opened on the top of the main rail 2, and side slide grooves 8 are opened on both sides of the main rail 2. The plurality of support components are slidably arranged on the plurality of main rails 2 for supporting the roof.

[0052] A plurality of auxiliary rails 6 are also provided on the top of the main support frame 1, and the auxiliary rails 6 are connected to the main rails 2. A steering assembly for adjusting the moving direction is provided inside the auxiliary rails 6, and the steering assembly includes an auxiliary slide groove 11 opened on the top of the auxiliary rail 6, and a plurality of rectangular notches 13 used in conjunction with the main slide groove 7 are opened on both sides of the auxiliary rail 6.

Second rectangular positioning blocks 14 are fixedly connected on both sides of the auxiliary rail 6, and second rectangular positioning grooves 12 are opened on both sides of the auxiliary rail 6. The auxiliary rails 6 are inserted between the main rails 2. When the main rail 2 and the auxiliary rail 6 are directly docked, the second rectangular positioning block 14 is engaged with the corresponding first rectangular positioning groove 9, and the second rectangular positioning groove 12 is engaged with the corresponding first rectangular positioning block 10.

[0053] The supporting assembly includes a rectangular frame 3 and a supporting top plate 5. A mounting rod 18 is fixedly connected to the middle position of the top of the rectangular frame 3. A universal bearing 17 (also called a joint bearing) is arranged between the top of the mounting rod 18 and the bottom of the supporting top plate 5. The bearing can adjust the distance between the rectangular frame 3 and the supporting top plate 5 according to needs. A rectangular frame 19 is fixedly connected to the four corners of the rectangular frame 3. An adjusting assembly for adjusting the inclination angle of the supporting top plate 5 is arranged inside the rectangular frame 19. The adjusting assembly includes a No. 1 round hole 26 opened inside the rectangular frame 19. An adjusting nut 28 is rotatably connected to the top of the rectangular frame 19. The internal thread of the adjusting nut 28 penetrates the lifting rod 4. The top of the lifting rod 4 is fixedly connected to the rectangular top plate 16. The rectangular top plate 16 conflicts with the bottom of the supporting top plate 5. The adjusting assembly includes two fixed blocks 22 fixedly connected to the top of the rectangular frame 19 and symmetrically arranged. The internal thread of the fixed block 22 penetrates the adjusting screw 31. One end of the adjusting screw 31 is rotatably connected to the sliding clamping plate 24.

[0054] One side of the sliding and tightening plate 24 is fixedly connected with two symmetrically arranged connecting rods 29, one side of the bottom of the two connecting rods 29 is fixedly connected with the same side plate 25, one side of the side plate 25 is fixedly connected with an insertion rod 30, both sides of the rectangular frame 19 are provided with insertion holes 27, the insertion holes 27 are connected with the No. 1 round hole 26, and one side of the lifting rod 4 is provided with a plurality of slots 23, the insertion rod 30 passes through the insertion holes 27 and engages with the slots 23. When the entire adjustment assembly is working, the relative positions of the side plate 25, the sliding and tightening plate 24, and the connecting rod 29 remain unchanged. Since the fixed block 22 is fixed on the top of the rectangular frame 19, the relative positions of the sliding and tightening plate 24 and the fixed block 22 can be adjusted by rotating the adjusting screw 31, so that the sliding and tightening plate 24 is pressed against the adjusting nut 28.

[0055] The bottom of the rectangular frame 19 is fixedly connected with a support block 20, and a sliding assembly is arranged inside the support block 20 to facilitate the translation of the top plate 5. The sliding assembly includes a No. 2 circular hole 47 opened inside the support block 20, and a rotating shaft 48 is passed through the internal rotation of the No. 2 circular hole 47. The bottom of the rotating shaft 48 is fixedly connected with a connecting plate 45, and the internal rotation of the connecting plate 45 is provided with a main moving wheel 21, which is used in conjunction with the main slide 7. The top of the rotating shaft 48 is fixedly connected with a No. 1 limit block 32, and the outer wall of the rotating shaft 48 is provided with a plurality of slots 49;

[0056] Anti-deviation components for preventing the device from deviating are arranged on both sides of the support block 20. The anti-deviation components include two circular positioning grooves 50 respectively arranged on both sides of the support block 20. A circular positioning rod is slidably penetrated inside the circular positioning groove 50. One end of the two circular positioning rods is fixedly connected to the same mounting plate 33. The bottom of the mounting plate 33 is fixedly connected to an inclined plate 35. The bottom of the inclined plate 35 is fixedly connected to two symmetrically arranged vertical plates 36. One side of the vertical plate 36 is rotatably connected to an auxiliary moving wheel 37. The auxiliary moving wheel 37 is used in conjunction with the side slide groove 8. A bidirectional screw rod 38 is rotatably penetrated inside the support block 20. The two ends of the bidirectional screw rod 38 are respectively threaded through the two mounting plates 33, and the two ends of the bidirectional screw rod 38 are fixedly connected with the second limit block 34. The bottom of the inclined plate 35 is slidably connected with the sliding strip plate through the slider rail. The slide rail used in conjunction with the sliding strip plate at the bottom of the inclined plate 35 is perpendicular to the side slide groove 8. Two symmetrically arranged springs are fixedly connected between one side of the sliding strip plate and one side of the inclined plate 35. A clamping rod is fixedly connected to one side of the mounting plate 33. Clamping holes 43 are provided on both sides of the support block 20. One end of the clamping rod passes through the clamping hole 43 and extends to the inside of the No. 2 circular hole 47 and is clamped and fixed with the clamping groove 49.

[0057] When the large-span gymnasium steel structure roof is in use, a track can be laid on the main support frame 1 above the lower steel structure below the roof according to needs, and multiple main tracks 2 are installed in the main moving direction. The multiple main tracks 2 are fixed by plugging the first rectangular positioning block 10 and the first rectangular positioning groove 9. At the position where lateral movement is required, the same auxiliary track 6 is set between the two main tracks 2 at the position, and the second rectangular positioning block 14 is plugged into the first rectangular positioning groove 9, and the second rectangular positioning groove 12 is plugged into the first rectangular positioning block 10, so as to complete the connection between the main track 2 and the auxiliary track 6;

[0058] After the connection is completed, the multiple support blocks 20 are placed on the top of the main support frame 1. At this time, the bottom of the main moving wheel 21 cooperates with the main slide 7 to drive the support top plate 5 to move. At this time, the second limit block 34 can be rotated, and the second limit block 34 drives the two-way screw rod 38 to rotate. The two-way screw rod 38 drives the two mounting plates 33 to approach each other. At this time, the mounting plate 33 drives the circular positioning rod to enter the inside of the circular positioning groove 50, and the clamping rod enters the inside of the clamping hole 43 and enters the inside of the clamping groove 49, so that the angle of the rotating shaft 48 can be fixed;

[0059] At the same time, since the connecting plate 45 is fixedly connected to the bottom of the rotating shaft 48, when the angle of the main moving wheel 21 needs to be adjusted, the No. 2 limit block 34 can be rotated again to make the two mounting plates 33 move away from each other, and then after the braking state of the rotating shaft 48 is released, the No. 1 limit block 32 can be rotated to adjust the angle of the main moving wheel 21. When turning is required, when the main moving wheel 21 moves from the inside of the main slide groove 7 to the inside of the auxiliary slide groove 11, the angle of the main moving wheel 21 is rotated so that the device can move horizontally as a whole, which is convenient for changing the moving direction of the device. After moving to a suitable position, the angle of the main moving wheel 21 can be adjusted again so that the main moving wheel 21 moves to the inside of the main slide groove 7 again, thereby realizing support for different arch beam positions of the steel structure roof support system.

[0060] And when the support block 20 moves, the auxiliary moving wheel 37 is located inside the side slide groove 8, which can ensure the stability of the device movement. There is a gap between the auxiliary moving wheel 37 and the inner wall of one side of the side slide groove 8. At this time, when subjected to strong winds and external forces, the support block 20 can be slightly moved laterally, and the inclined plate 35 squeezes the spring and approaches the sliding strip plate. After the impact is completed, the main moving wheel 21 can be reset by the spring to achieve the effect of slowing down the deviation of the device; because the slide rail used in conjunction with the sliding strip plate at the bottom of the inclined plate 35 is perpendicular to the side slide groove 8, the cooperation between the slide rail at the bottom of the inclined plate 35 and the top slider of the sliding strip plate limits the movement of the sliding strip plate, so that the sliding strip plate will not slide out with the sliding of the auxiliary moving wheel 37.

[0061] When it is necessary to adjust the height of the lifting rod 4, the adjusting screw 31 can be rotated. At this time, the adjusting screw 31 can drive the sliding clamping plate 24 to move laterally, and the sliding clamping plate 24 no longer presses against the adjusting nut 28, so that the adjusting nut 28 can rotate normally, and the sliding clamping plate 24 can drive the connecting rod 29 to move laterally, and the connecting rod 29 drives the side plate 25 to move laterally, and the side plate 25 drives the plug rod 30 to retract, and the plug rod 30 is moved out from the inside of the slot 23, which can release the braking state of the lifting rod 4. At this time, the adjusting nut 28 can be rotated to adjust the height of the lifting rod 4. By adjusting the height of the four lifting rods 4, the supporting top plate 5 can be maintained at different angles, so that the angle of the supporting top plate 5 can adapt to a variety of situations, realize surface contact with different arches of the steel structure roof arch beam, improve the applicable scope of the lifting device, increase the contact area, and enhance stability.

[0062] The construction method of the large-span gymnasium steel structure roof specifically includes the following steps:

[0063] S1. Track laying and connection:

[0064] According to the operation requirements, the main track 2 is laid on the main support frame 1 on the top of the lower steel structure under the roof, and the main track 2 is connected by fixing the first rectangular positioning block 10 with the corresponding first rectangular positioning groove 9. The auxiliary track 6 is installed at the position where the horizontal movement is required, and the auxiliary track 6 is connected to the main track 2 by the second rectangular positioning block 14 and the corresponding first rectangular positioning groove 9 and the second rectangular positioning groove 12 and the corresponding first rectangular positioning block 10.

[0065] S2. Installation of support block 20 and moving wheel:

[0066] Place multiple support blocks 20 on top of the main support frame 1, ensure that the main moving wheel 21 is matched with the main slide 7, and install the auxiliary moving wheel 37 into the side slide 8 to ensure stability;

[0067] S3, Angle and height adjustment:

[0068] By rotating the second stopper 34 and the first stopper 32, the angle of the main moving wheel 21 is adjusted to adapt to different moving directions, the adjusting screw 31 is rotated to release the braking state of the lifting rod 4, and then the adjusting nut 28 is rotated to adjust the height of the lifting rod 4 to adjust the angle and height of the supporting top plate 5;

[0069] S4. Movement and Operation:

[0070] The push or drive device moves along the track to the designated position. When turning is required, the main moving wheel 21 is moved from the main chute 7 to the auxiliary chute 11, and the angle is adjusted to achieve lateral movement. After reaching the target position, the angle of the main moving wheel 21 is adjusted again to return to the main chute 7 to continue moving forward or operating;

[0071] S5. Security monitoring and maintenance:

[0072] During the operation, the stability of the device should be continuously monitored to ensure that there is no risk of overturning. The wear of the track, moving wheels, lifting rod 4 and other components should be regularly checked, and maintenance and replacement should be carried out in a timely manner.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the present invention.
