Description

Technical Field

[0001] The present invention relates to the technical field of roof maintenance construction, in particular to a high-precision modular metal roof runway system. Background Art

[0002] Metal roofing is increasingly being used in stadium construction. However, its construction presents its own challenges. Traditional roof bridle systems typically utilize on-site splicing, relying on the construction of a cradle and patching keels for on-site welding and assembly. This on-site welding is not only inefficient but also requires frequent material cutting, resulting in waste. Furthermore, the welding process can cause deformation in the ribs, leading to increased installation errors and requiring on-site positioning adjustments by workers, resulting in low construction efficiency. Furthermore, welding assembly can easily damage the material's anti-corrosion coating, requiring manual re-application of the anti-corrosion coating after welding. This re-application has poor adhesion and is prone to rust in high-humidity environments, making it unsuitable for use. Summary of the Invention

[0043] like Figures 1-4 As shown, the present invention provides a high-precision modular metal roof runway system having a first direction X and a second direction Y intersecting each other.

[0044] In a preferred embodiment, the first direction X and the second direction Y intersect perpendicularly.

[0045] In some embodiments, the high-precision modular metal roofing bridle system includes a prefabricated rigid frame 10 and a main steel structure 40; specifically, the prefabricated rigid frame 10 is connected to the main steel structure 40, and the prefabricated rigid frame 10 includes a first vertical steel pipe 11, a second vertical steel pipe 12, a first transverse steel pipe 13, a diagonal bracing steel pipe 15, and a second transverse steel pipe 16. The first vertical steel pipe 11 and the second vertical steel pipe 12 are spaced apart along the second direction Y. One end of the first vertical steel pipe 11 is connected to the main steel structure 40, and the first transverse steel pipe 13 connects the first vertical steel pipe 11 and the second vertical steel pipe 16 along the second direction Y. Tube 12, one end of the diagonal bracing steel pipe 15 is connected to the first horizontal steel pipe 13, and the other end is connected to the main steel structure 40, the second horizontal steel pipe 16 extends along the second direction Y and is connected to the second vertical steel pipe 12, the second horizontal steel pipe 16 and the first horizontal steel pipe 13 are spaced apart along the first direction X, and a prefabricated rigid frame 10 is adopted, so that the first vertical steel pipe 11, the second vertical steel pipe 12, the first horizontal steel pipe 13, the diagonal bracing steel pipe 15 and the second horizontal steel pipe 16 can be prefabricated in the factory and hoisted on site, which can realize the modular installation of the horseway system, improve the installation accuracy, and reduce the amount of high-altitude work.

[0046] In a preferred embodiment, fastening bolts 14 are provided at both ends of the first transverse steel pipe 13 along the second direction Y, the first transverse steel pipe 13 is connected to the first vertical steel pipe 11 by the fastening bolts 14, and the first transverse steel pipe 13 is connected to the second vertical steel pipe 12 by the fastening bolts 14; the use of the fastening bolts 14 has a certain buffering effect on the stress changes caused by the later load and wind load added to the horseway, and can avoid deformation of the prefabricated rigid frame 10.

[0047] In order to prevent the prefabricated rigid frame 10 from being eroded by rainwater, the high-precision modular metal roof walkway system also includes a waterproof structure 20, which is arranged on the side of the second vertical steel pipe 12 facing away from the first vertical steel pipe 11, and at least part of the waterproof structure 20 extends to the side of the second transverse steel pipe 16 facing away from the first transverse steel pipe 13, thereby preventing rainwater from directly contacting the prefabricated rigid frame 10, thereby preventing rainwater from eroding the prefabricated rigid frame 10 and extending the service life of the prefabricated rigid frame 10.

[0048] In some embodiments, the waterproof structure 20 includes a first aluminum veneer 21, a second aluminum veneer 22, a third aluminum veneer 23 and a U-shaped member 24. The first aluminum veneer 21 and the second aluminum veneer 22 are spaced apart along the first direction X. The first aluminum veneer 21 and the second aluminum veneer 22 are connected by a U-shaped member 24. The U-shaped member 24 is connected to the second vertical steel pipe 12. The third aluminum veneer 23 is arranged on the side of the second transverse steel pipe 16 facing away from the first transverse steel pipe 13. One end of the third aluminum veneer 23 is connected to the end of the second transverse steel pipe 16, and the other end is connected to the second aluminum veneer 22 through the U-shaped member 24. The use of multiple sections of aluminum veneer can achieve rapid splicing and can avoid large deformation of the aluminum veneer during the assembly process, which affects the aesthetics. The setting of the U-shaped member 24 can avoid gaps between adjacent two aluminum veneers, which causes rainwater to penetrate and contact the prefabricated rigid frame 10, and can play a waterproof role.

[0049] In some embodiments, in order to improve the connection strength between the first aluminum veneer 21 and the second vertical steel pipe 12, and between the second aluminum veneer 22 and the second vertical steel pipe 12, a first inner tube 121 is provided inside the second vertical steel pipe 12, and the U-shaped member 24 is connected to the first inner tube 121 by a first screw 25. The provision of the first inner tube 121 further improves the structural strength and rigidity of the second vertical steel pipe 12, thereby ensuring the stability of the aluminum veneer after installation.

[0050] In some embodiments, rainwater cannot be prevented from seeping into one side of the prefabricated rigid frame 10 through the gap between the first screw 25 and the U-shaped member 24. For this reason, a first sealant 27 is provided between the U-shaped member 24 and the second vertical steel pipe 12, and the first sealant 27 can also enable the aluminum single plate to have a certain buffering effect on the stress changes caused by the wind load; preferably, the first sealant 27 is a polysulfide sealant to avoid water leakage and corrosion, and the anti-corrosion performance of the polysulfide sealant will not be attenuated.

[0051] In some embodiments, the first aluminum single plate 21 has a first bending portion 211, and the first bending portion 211 is connected to one end of the U-shaped part 24 through a locking member 26. The second aluminum single plate 22 has a second bending portion 221, and the second bending portion 221 is connected to the other end of the U-shaped part 24 through a locking member 26. Through the bending design, the first aluminum single plate 21 and the second aluminum single plate 22 can cooperate with the U-shaped part 24 at their junction, so that the locking member 26 is embedded, thereby forming a good waterproof effect.

[0052] In some embodiments, in order to further improve the sealing between two adjacent aluminum veneers, the U-shaped member 24 may be filled with foam rods and sealant to form a seal between the two adjacent aluminum veneers.

[0053] In some embodiments, in order to further improve the installation firmness of the first aluminum single plate 21, a second inner tube 122 is provided inside the end of the second vertical steel tube 12 away from the second transverse steel tube 16, and the end of the first aluminum single plate 21 away from the second transverse steel tube 16 has a third bending portion 212, and the third bending portion 212 is connected to the second inner tube 122 by a second screw 28.

[0054] In some embodiments, a second sealant 29 is provided between the third bend 212 and the second vertical steel pipe 12 to further improve the waterproof effect; preferably, the second sealant 29 is polysulfide sealant to avoid water leakage and corrosion, and the anti-corrosion performance of the polysulfide sealant will not be attenuated.

[0055] In order to improve the drainage capacity of the high-precision modular metal roof runway system, the high-precision modular metal roof runway system also includes a drainage system 30, which is arranged between the first vertical steel pipe 11 and the second vertical steel pipe 12, and the drainage system 30 is connected to the first horizontal steel pipe 13.

[0056] In some embodiments, the drainage system 30 includes a first flashing plate 31, a second flashing plate 32 and a water guide plate 33, wherein the water guide plate 33 is arranged on the side of the first horizontal steel pipe 13 away from the main steel structure 40, and along the second direction Y, the water guide plate 33 has a first end 33a and a second end 33b extending along the first direction X; the first flashing plate 31 is connected to the first vertical steel pipe 11, and at least a portion of the first flashing plate 31 extends along the first direction X and is connected to the first end 33a of the water guide plate 33; the second flashing plate 32 is connected to the second vertical steel pipe 12, and at least a portion of the second flashing plate 32 extends along the first direction X and is connected to the second end 33b of the water guide plate 33; the flashing plate can be used to guide rainwater to gather at the water guide plate 33, effectively preventing rainwater from eroding the prefabricated rigid frame 10 and causing leakage.

[0057] In some embodiments, the first flashing plate 31 and the second flashing plate 32 are both provided with a third screw 34, the first flashing plate 31 is connected to the first vertical steel pipe 11 through the third screw 34, and the second flashing plate 32 is connected to the second vertical steel pipe 12 through the third screw 34, and the third screw connection position is waterproofed, such as by arranging a sealing gasket or sealant.

[0058] In some embodiments, along the first direction X, the height of the water deflector 33 near the first end 33a is greater than the height of the water deflector 33 near the second end 33b, so that the water deflector 33 forms a slope with an inclination angle θ; wherein the inclination angle θ satisfies the following: 1° ≤ θ ≤ 15°. This ensures that rainwater flows along a predetermined path for easy collection. Furthermore, the sloped design prevents water from accumulating on the water deflector 33, thereby preventing corrosion, leakage, and other problems.

[0059] In some preferred embodiments, the tilt angle θ is 2°.

[0060] In some embodiments, in order to further improve the waterproof performance, the drainage system 30 also includes a drain pipe 35, which is arranged on the side of the water guide plate 33 close to the second end 33b. The drain pipe 35 is configured to receive water collected by the water guide plate 33 so as to drain the accumulated water in the horse trail system in time to avoid corrosion, leakage and other phenomena.

[0061] In summary, an embodiment of the present invention provides a high-precision modular metal roof horseway system, which adopts a prefabricated rigid frame 10. The prefabricated rigid frame 10 includes a first vertical steel pipe 11, a second vertical steel pipe 12, a first horizontal steel pipe 13, a diagonal bracing steel pipe 15 and a second horizontal steel pipe 16. Through splicing, it can realize the assembly method of factory prefabrication and on-site hoisting, which can realize modular installation of the horseway system, improve installation accuracy, and reduce the amount of high-altitude work; the waterproof structure 20 is set to effectively prevent the prefabricated rigid frame 10 from corrosion, and the drainage system 30 can drain the accumulated water in the horseway system in time to avoid corrosion, leakage and other phenomena.
