[0061] like Figures 1-5 As shown, the metal roof installation method provided in this embodiment includes:

[0062] Install the C-shaped secondary purlin 1 into the corrugated base plate 2 on the ground to form a load-bearing assembly 100, and process and assemble multiple load-bearing assemblies 100;

[0064] Install the structural layer modules 200 to the supporting assembly 100 in a one-to-one correspondence to form a plurality of assembly units 300;

[0065] Connect multiple assembly units 300 to the main purlin 3 in sequence, and connect two adjacent assembly units 300 to each other;

[0066] After the multiple assembling units 300 are installed, the upper structure 400 is installed on top of the multiple assembling units 300 .

[0067] The C-shaped secondary purlin 1 can be a hot-dip galvanized C-shaped steel tube, and the corrugated base plate 2 can be a double-sided aluminum-zinc-magnesium corrugated steel plate. The C-shaped secondary purlin 1 and corrugated base plate 2 are combined to form a load-bearing assembly 100. The load-bearing assembly 100, together with the assembled structural layer modules 200, forms an assembly unit 300. The processing and formation of the multiple assembly units 300 are all completed on the ground. The multiple assembly units 300 are then sequentially installed to the main purlins, and the superstructure 400 is installed on top of the multiple assembled assembly units 300, completing the overall installation of the metal roof.

[0068] The metal roof installation method provided by the embodiment converts most high-altitude operations into ground operations, reduces high-altitude operations, reduces the safety risks of independent high-altitude construction of each component in the load-bearing assembly 100 and the construction layer module 200, and has low construction difficulty of ground operations, which is conducive to improving construction efficiency and shortening the construction period.

[0069] In other possible embodiments, after the load-bearing assembly 100 and the construction layer module 200 are respectively prefabricated, the plurality of load-bearing assemblies 100 can be sequentially connected to the main purlin 3, and then the plurality of construction layer modules 200 are one by one and corresponding installed to the load-bearing assembly 100 on the main purlin 3. The specific construction steps can be determined according to actual conditions.

[0070] As shown in FIG. 1, Figure 1 In some embodiments, the profiled bottom plate 2 includes a bottom wall 21, a first side wall 22 and a second side wall 23, the first side wall 22 and the second side wall 23 are located at opposite ends of the bottom wall 21 along the width direction of the bottom wall 21, the first side wall 22 and the second side wall 23 are vertically extended upward from the bottom wall 21, the first side wall 22 is horizontally bent at the top end to form a first flange 24 toward the second side wall 23, and a first accommodating space is formed between the first flange 24, the first side wall 22 and the bottom wall 21.

[0071] The C-shaped secondary purlin 1 is installed into the profiled bottom plate 2 on the ground, specifically including:

[0072] The C-shaped secondary purlin 1 is inserted into the first accommodating space, and the opening of the C-shaped secondary purlin 1 faces the second side wall 23.

[0073] Through such a design, the C-shaped secondary purlin 1 is hidden in the profiled bottom plate 2, and when the assembly unit 300 is connected to the main purlin 3, the bottom wall 21 of the profiled bottom plate 2 is directly lapped on the main purlin 3, compared with the installation structure of the traditional metal roof, the lining purlin and the several-shaped adapter can be omitted, thereby saving the amount of steel and shortening the construction time.

[0074] In addition, a second accommodating space is formed between the C-shaped secondary purlin 1, the bottom wall 21 and the second side wall 23;

[0075] The construction layer module 200 is one by one and corresponding installed to the load-bearing assembly 100 to form a plurality of assembly units 300, specifically including:

[0076] The construction layer module 200 is one by one and corresponding installed to the second accommodating space.

[0077] The second accommodating space provides a dedicated embedding area for the construction layer module 200, so that the positioning and installation of the construction layer module 200 are more convenient, and the construction layer module 200 and the bearing assembly 100 can be quickly docked and fixed, reducing the complexity of adjustment and alignment.

[0078] As shown in Figure 1 In some embodiments, the second flange 25 is formed at the top end of the second side wall 23, and the extension direction of the second flange 25 is consistent with that of the first flange 24.

[0079] The plurality of assembly units 300 are sequentially connected to the main purlin 3, and adjacent two assembly units 300 are connected to each other, specifically including:

[0080] The plurality of assembly units 300 are sequentially hoisted to the preset positions on the main purlin 3 by hoisting equipment, so that the second flange 25 is overlapped on the top of the first flange 24 of the adjacent assembly unit 300;

[0081] The assembly unit 300 is connected to the main purlin 3 by the first fastener, and the adjacent two assembly units 300 are connected by the second fastener.

[0082] Through such a design, the second flange 25 and the first flange 24 are overlapped with each other, which provides natural alignment guidance for the adjacent two assembly units 300, and is beneficial to simplify the installation process; in addition, the first fastener can stably and firmly connect the assembly unit 300 to the main purlin 3, and the second fastener can further enhance the connection strength of the adjacent two assembly units 300, compared with the traditional welding method, the use of fasteners is more convenient for on-site control of installation quality.

[0083] Optionally, the first fastener and the second fastener can be bolts, screws, etc., which are not limited here.

[0084] Optionally, the hoisting equipment can be a vehicle-mounted crane, a crane, etc., which is not limited here.

[0088] The second hole is punched in the C-shaped secondary purlin 1, the third hole is punched in the first side wall 22, and the fourth hole is punched in the second side wall 23, so that the second fastener can pass through the second hole, the third hole, and the fourth hole of the second side wall 23 of the adjacent assembly unit 300 in sequence, thereby connecting the adjacent two assembly units 300 by the second fastener.

[0089] By pre-punching on the C-shaped purlin 1 and the profiled bottom plate 2, the hole position deviation problem can be reduced or avoided according to the design drawing, so that the first fastener and the second fastener can be quickly installed by the construction personnel through the reserved hole when the assembly unit 300 is installed, which is helpful to speed up the construction speed.

[0090] In some embodiments, the plurality of construction layer modules 200 are assembled on the ground, specifically including:

[0091] The roof vapor barrier, thermal insulation rock wool, sound insulation rock wool, and thermal insulation film are sequentially combined from bottom to top to form the construction layer module 200.

[0092] The roof vapor barrier is located at the bottom layer to prevent water vapor from penetrating upwards and protect the thermal insulation layer. The thermal insulation rock wool is located above the roof vapor barrier to provide thermal insulation and prevent heat loss. The sound insulation rock wool is usually above the thermal insulation layer to help reduce noise transmission. The thermal insulation film is located at the top layer to protect the materials below and provide additional thermal insulation effect.

[0093] Further, after the roof vapor barrier, thermal insulation rock wool, sound insulation rock wool, and thermal insulation film are sequentially combined from bottom to top to form the construction layer module 200, further including:

[0094] The joints in the construction layer module 200 are sealed.

The metal roof deck provides a solid support structure for the roof, and the laying of the waterproofing membrane and the design of the standing seam roof together form a multi-layer waterproofing system, significantly improving the waterproofing performance of the roof, effectively preventing rainwater penetration, and the standing seam roof further enhances the overall rigidity, helping to resist wind load and other external pressure.

[0100] Further, after the waterproofing membrane is laid, the joints of the waterproofing membrane are treated by hot air fusion welding to form a continuous waterproof layer.

[0101] Optionally, the waterproofing membrane includes, but is not limited to, a TPO (thermoplastic polyolefin) waterproofing membrane.
