Description

Technical Field

[0001] The invention relates to the technical field of multi-arch combined load-bearing structures, in particular to a multi-arch combined load-bearing structure system and a process for a large-span arch steel structure system. Background Art

[0002] Large-span arched steel structure systems are used in factories, gymnasiums or large buildings. The large-span structure is used to build the entire building without using concrete or other brick-concrete structures. When the span is large, in order to ensure that there is no pillar support on the inside, a multi-joint force-bearing structure is used to support the arched steel structure on both sides, so there is no need to use multiple pillars for support, thus saving space.

[0003] According to the existing Chinese patent CN114482278A, a multi-arch joint force-bearing self-balancing large-span arch steel structure system includes a central arch and a large-span curved roof steel structure frame arranged on both sides of the central arch, and the large-span curved roof steel structure frames at the two wings. While achieving a large span in two-dimensional directions of the plane under the arch of the structure, in addition to setting a supporting side column at one end, the space under the roof no longer needs columns for support, thereby improving the freedom of planning and layout in the building space using the structure. In theory, as long as the height of the main arch frame is high enough, the large-span curved roof steel structure frames on the two wings of the structure can have a sufficiently high clearance height to meet the clearance height requirements of different large-span buildings;

[0004] The multi-arch joint force-bearing structure provided by the patent is connected and supported by multiple top trusses between the two upper arches, but the straight top trusses support the overall weight, and the linear structure has a poor bearing capacity. At the same time, the existing large-span steel structure will lay colored steel tiles on its top after laying. The setting of the multi-arch joint force-bearing structure makes the colored steel tiles on both sides concave toward the middle, and the colored steel tiles will inevitably form uneven parts when welded and fixed, resulting in unevenness and depressions on the side close to the upper arch. Therefore, water will accumulate in the depression on rainy days, increasing the probability of corrosion of the colored steel tiles and reducing their service life. It is very troublesome to replace the colored steel tiles each time. At the same time, the dust from leaves and dust floating in the air is also easy to accumulate on the colored steel tiles on the side close to the upper arch, further increasing the probability of corrosion of the colored steel tiles.

[0005] Therefore, it is necessary to provide a multi-arch joint force-bearing structure system and process for a large-span arch steel structure system to solve the above technical problems. Summary of the invention

The moving part 4 includes a synchronous driving mechanism 7 for driving the two wiper blades 5 to switch high and low positions when it moves to the side of the second color steel tile 204. The moving part 4 also includes a driving frame 41 fixed on its outer wall close to one side of the arched support steel frame 101. A second slide rail 10 is fixed on the side of the arched support steel frame 101 close to the moving part 4.

The moving mechanism 6 is installed on the outer wall of the first color steel tile 103, and is used to drive the two moving parts 4 to move synchronously;

[0061] After rainy weather or after dust has accumulated for a certain period of time, the moving mechanism 6 is driven to make the moving part 4 slide left and right on the arched support steel frame 101, thereby driving the wiper blade 5 to slide from the top of the second color steel tile 204. The wiper blade 5 allows rainwater or dust impurities on the second color steel tile 204 to be scraped off to both sides of the second color steel tile 204, thereby achieving the effect of water removal, extending the service life of the color steel tile, and reducing the probability of its corrosion.

[0062] The moving mechanism 6 includes a moving top plate 61, a driving rod 62, a rotating shaft 63, a motor 64, a first gear 65 and a gear ring 66.

[0063] When movement is required, the rotating shaft 63 is driven to rotate by the driving motor 64, so that the first gear 65 rotates, and the first gear 65 shifts the gear ring 66, so that the movable top plate 61 slides on the outer wall of the arc-shaped slide rail 8, until it slides to the end of the arc-shaped slide rail 8, the motor 64 stops and reverses, so that the movable top plate 61 slides to the other end of the arc-shaped slide rail 8, until it slides to the other end, the motor 64 switches the rotation direction again, so that the movable top plate 61 reciprocates between the two ends of the arc-shaped slide rail 8, and the driving rod 62 is driven to move while the movable top plate 61 slides, pushing the driving frame 41 to slide, thereby driving the wiper blade 5 to slide back and forth to wipe water and dust;

[0064] The synchronous drive mechanism 7 includes a first rack 71, a first rack 71 and a push bar 76. The first racks 71 are respectively slidably mounted on the two ends of the outer wall of the moving member 4 away from the arched support steel frame 101, and the two first racks 71 are arranged one high and one low. The outer wall of the moving member 4 is symmetrically fixed with two fourth slide rails 12. The first rack 71 is slidably connected to the fourth slide rail 12 through the second slide groove. The wiper blade 5 is fixed to the bottom of the first rack 71. The second gear 7265 is rotatably connected to the outer wall of the moving member 4 close to the first rack 71 through an axle pin, and the two first racks 71 are meshed with the gear 65.

The second gear 7265 is also meshed and connected with the second gear 7265. The bent portion 731 is formed at the end of the second rack 73, and one side of the bent portion 731 abuts against the outer wall of the moving member 4. The limiting assembly 74 is installed between the second rack 73 and the moving member 4 and is used to limit the position of the second rack 73. The pulling block 75 is fixed to the outer wall of the arched support steel frame 101 away from the bent portion 731. The pushing bar 76 is fixed to the side of the arched support steel frame 101 away from the pulling fast, and the pushing bar 76 and the pulling block 75 both correspond to the bent portion 731. The limiting assembly 74 includes an arched spring piece 741, which is fixed to the top of the second rack 73 and is located between the second rack 73 and the moving member 4. Two slots 742 are provided, which are sequentially opened on the outer wall of the moving member 4, and one side of the arched protrusion of the arched spring piece 741 is engaged with one of the slots 742.

[0065] When the moving part 4 moves to one side of the arc slide rail 8, the bending portion 731 is blocked by the pulling block 75, and the moving part 4 continues to move toward the end, pulling the quick-pulling bending portion 731 causes the second rack 73 to slide and drive the second gear 7265 to rotate, and at the same time, the two first racks 71 are moved at the same time, one first rack 71 rises and the other first rack 71 falls, and the arched spring piece 741 moves out of one slot 742 and then pushes into the other slot 742. At this time, the moving part 4 reaches the end, and the two wiper blades 5 are completely and switch positions. Then the moving part 4 moves in the opposite direction and uses the other wiper blade 5 to wipe the water until it reaches the other end. The bending portion 731 is pushed by the pushing bar 76 to slide in the opposite direction relative to the moving part 4, and the second gear 7265 is rotated again. The two first racks 71 slide again to switch the position of the wiper blade 5. Compared with only a single wiper blade 5, the time interval for manual replacement of the wiper blade 5 is extended.

Compared with the fixed connection, the driving rod 62 can also roll on the inner wall of the driving frame 41 when moving, so as to reduce friction by rolling instead of sliding.
