In addition, unless otherwise specified, "multiple" means two or more.

[0036] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0037] like Figure 1-Figure 5 As shown, some embodiments of the metal roof structure for a stadium include: a purlin 1, a connecting unit 2, a first panel 3, a first keel 4, a second keel 5, and a second panel 6. Each component is detachably connected via bolts. Specifically, the first panel 3 is an aluminum-magnesium-manganese plate, and the second panel 6 is an aluminum veneer.

[0038] The purlin 1 is configured to be detachably connected to the steel structure 7 of the stadium. The connection unit 2 is connected to the purlin 1, and the connection unit 2 is provided in plurality and arranged along the extension direction of the purlin 1. The first panel 3 is detachably connected between two adjacent connection units 2. The first keel 4 is provided in plurality and is detachably connected to the connection unit 2 in a one-to-one correspondence. The second keel 5 is provided in plurality and is provided in a one-to-one correspondence on the first keel 1, and the second keel 5 is configured to slide up and down or be fixed in position relative to the first keel 4. The second panel 6 is detachably connected to two adjacent second keels 5 on both sides, and the second panel 6 is provided in plurality, and is spaced apart between two adjacent second panels 6. Specifically, the first keel 4 and / or the second keel 5 have through-holes extending up and down, and the first keel 4 and the second keel 5 are both made of U-shaped channel steel. In this way, when the first keel 4 and the second keel are installed by bolts, the up and down positions of the two can be adjusted, and the positions of the two can be fixed after tightening the bolts.

[0039] Based on the above-mentioned structural setting, the longitudinal position of the second panel 6 can be adjusted by sliding the second keel 5 up and down relative to the first keel 4 or fixing its position. The two adjacent second panels 6 are arranged at intervals, and the horizontal position of the second panel 6 can be adjusted, so that the installation position can be easily adjusted, the positioning accuracy requirements can be reduced, and the structural deformation and temperature deformation can be adapted.

[0040] like Figure 3 As shown, in some embodiments, a purlin bracket 8 is included, and the purlin 1 is installed on the steel structure 7 through the purlin bracket 8. The purlin bracket 8 is welded to the steel structure 7, and the purlin 1 is connected to the purlin bracket 8 by bolts. Specifically, the purlin 1 is made of I-beam.

[0041] like Figure 1 As shown, in some embodiments, a bottom plate 9 is included, which is detachably connected to the bottom of the purlin 1. The bottom plate 9 is made of a corrugated steel plate, and the bottom plate 9 is fixed to the purlin 1 by anti-tapping screws.

[0042] like Figure 1 As shown, in some embodiments, a moisture-proof layer 10 and a sound-absorbing cotton layer 11 are included, and the moisture-proof layer 10 and the sound-absorbing cotton layer 11 are laid on the bottom plate 9 in sequence and are both located below the first panel 3. In this way, it has the effect of moisture-proof and sound insulation.

[0043] like Figure 1 、 Figure 4 and Figure 5 In some embodiments, the connecting unit 2 includes a first support member 21, a fixing seat 22, and a clamp 23. The first support member 21 is detachably connected to the purlin 1, the fixing seat 22 is detachably connected to the first support member 21, and the clamp 23 is detachably connected to the bottom of the first keel 4. The clamp 23 is used to fix the first panel 3 to the fixing seat 22. In this way, the first panel 3 is easily installed and removed.

[0044] like Figure 5 As shown, in some embodiments, both sides of the first panel 3 have first folded edges 31 bent upwards, and the first folded edges 31 are clamped between the clamp 23 and the fixing seat 22. In this way, the first panel 3 is easy to install and remove.

[0045] like Figure 5 As shown, in some embodiments, the fixing base 22 includes a base plate 221, a vertical plate 222 connected to the base plate 221, and a support block 223 provided on the top of the vertical plate 222. The base plate 221 is connected to the purlin 1, and the support block 223 abuts against the inner surface of the first folded edge 31. In this way, the installation structure of the first panel 3 is stabilized.

[0046] like Figure 5 As shown, in some embodiments, the clamp 23 includes a first clamping plate 231, a second clamping plate 232 and a connecting piece 233. The first clamping plate 231 is connected to the bottom of the first keel 4. The first clamping plate 231 and the second clamping plate 232 are detachably connected by the connecting piece 233. A clamping groove 234 is formed between the first clamping plate 231 and the second clamping plate 232. The outer surface of the first folding edge 31 abuts against the clamping groove 234. In this way, the installation structure of the first panel 3 is stabilized.

[0047] like Figure 1 As shown, in some embodiments, a second support member 12 is included, and both sides of the second panel 6 have downwardly bent second folds 61, which are connected to the second keel 5 through the second support member 12. In this way, the installation structure of the second panel 6 is stable.

[0048] Based on the above-mentioned stadium metal roof structure, the second panel 6 can be easily removed for repair, replacement, cleaning, internal inspection and floodlighting inspection by simply loosening the bolts of a specific panel without having to deal with the entire adhesive seam. Disassembly causes little damage to the panel and system. The disassembly and reassembly process does not damage the second folded edge 61, connection unit 2, first keel 4 and second keel 5 of the second panel 6. The bolt holes are regular holes, and the reliability of repeated disassembly and assembly is high. The up and down movement between the first keel 4 and the second keel 5 and the horizontal movement of the second panel 6 provide the necessary adjustment space during installation and later, greatly reducing the requirements for the positioning accuracy of the first keel 4 and the second keel 5, making it easier to ensure the flatness and uniformity of the joints of large-area roofs. It can better adapt to structural deformation and temperature deformation. Long-term maintenance costs are significantly reduced, and single maintenance is fast, efficient, and has low material loss.

[0049] The construction method of the metal roof structure of a stadium according to other embodiments of the present invention comprises the following steps:

[0050] S1. Install the purlins on the steel structure of the stadium through purlin brackets. Connect the purlins and purlin brackets with bolts, and weld the purlin brackets to the steel structure.

[0052] S3. Lay the moisture-proof layer and the sound-absorbing cotton layer on the baseplate in sequence. Lay the moisture-proof layer and the sound-absorbing cotton layer along the direction of the purlin extension, with the overlap length of the materials not less than 100mm. Use butyl tape to secure the moisture-proof layer during laying, ensuring a tight overlap. After laying, the surface should be flat and tight, without distortion. Butyl tape should also be used to secure the sound-absorbing cotton layer. The laying should be smooth, without wrinkles or bulges, and the appearance should be good. Lay the layers in a butt-jointed manner, with tight joints.

[0053] S4. Install multiple first support members on the purlins and arrange them along the extension direction of the purlins, wherein the first support members are shaped like "J" pieces, and the "J" pieces are fixed to the purlins with self-tapping screws, and the self-tapping screws are spaced 500 mm apart along the extension direction of the purlins;

[0054] S5. Install multiple connection units on the first support member in a one-to-one correspondence, and install the first panel between two adjacent connection units;
