Description

Technical Field

[0001] This utility model relates to the field of roof waterproofing technology, and in particular to a flexible roof waterproofing structure. Background Technology

[0002] The existing power plant building employs an inverted roof design, placing the insulation layer on top of the waterproofing layer. The roof drainage system is a single-slope, organized external drainage system with multiple structural joints for independent drainage in different areas. However, this structural design results in persistent roof leaks, with multiple seepage points, some directly above the generating units. The leaking water falls directly onto the generator cover and electrical control panels, causing instability in the main plant's generating units and electrical equipment, threatening their safe operation. Furthermore, the frequent immersion of the roof's steel structure by leaks leads to corrosion, creating safety hazards. Utility Model Content

Figure 1 A schematic diagram of a flexible waterproof roof structure provided in an embodiment of this utility model.

[0031] Example 1

[0032] The power plant building employs an inverted roof design, placing the insulation layer above the waterproofing layer. The roof drainage system is a single-slope, organized external drainage system with multiple structural joints for independent drainage in different areas. However, this structural design results in persistent roof leaks, with multiple seepage points, some directly above the generating units. The leaking water falls directly onto the generator covers and electrical control panels, causing instability in the main plant's generating units and electrical equipment, threatening their safe operation. Furthermore, the frequent immersion of the roof's steel structure by leaks leads to corrosion, creating safety hazards.

[0033] In view of this, the present utility model provides a flexible waterproof roof structure, including: a main structure decorative layer 100, a flexible support structure and a waterproof structure, wherein the flexible support structure is disposed between the main structure decorative layer 100 and the waterproof structure; the waterproof structure includes a first waterproof layer 700 and a second waterproof layer 500, wherein the second waterproof layer 500 is disposed between the flexible support structure and the first waterproof layer 700.

[0034] The main structural decorative layer 100 is the original roof structure, specifically an inverted roof structure. A flexible support structure is installed above the original roof structure, and a waterproof structure is installed above the flexible support structure. The flexible support structure not only supports and fixes the waterproof structure but also provides thermal insulation, noise reduction, and reduces heat transfer from the roof. The first waterproof layer 700 is located at the top and serves as the primary drainage and waterproofing layer. The second waterproof layer 500 is located below the first waterproof layer 700 and provides a second layer of drainage and waterproofing for rainwater that has penetrated the first waterproof layer 700. This structural design transforms the original inverted roof structure into a regular roof structure, effectively improving roof leakage, ensuring the safe operation of the units inside the factory, and guaranteeing the safety of the roof steel structure.

[0035] In an optional embodiment, the flexible support structure includes an insulation layer 300 and a support layer 400. The insulation layer 300 is disposed between the main structure decorative layer 100 and the support layer 400, and a second waterproof layer 500 is disposed above the support layer 400.

[0036] Please see Figure 1 The insulation layer 300 is positioned between the original roof structure and the supporting layer 400, serving to provide thermal insulation, noise reduction, and reduce heat transfer from the roof. A waterproof structure is installed above the supporting layer 400, which serves to secure the insulation layer 300 below and support the waterproof structure above.

[0037] Specifically, in this embodiment, the insulation layer 300 includes a foam glass insulation board, which is provided with a special asphalt-based surface and a glass fiber surface.

[0038] The thickness of the foam glass insulation board is preferably 50mm, with a special asphalt-based surface and a glass fiber surface, which will not damage the original roof structure.

[0039] In this embodiment, the support layer 400 includes a PCSP metal disk.

[0040] By installing a PCSP metal plate on the foam glass insulation board, the waterproof structure above can be effectively supported, ensuring the stability of the overall structure.

[0041] In an optional embodiment, an adhesive layer 200 is provided between the insulation layer 300 and the main structure decorative layer 100.

[0042] Please see Figure 1 The bonding layer 200 uses a special adhesive commonly used in engineering, which can bond the insulation layer 300 and the main structure decorative layer 100. It mainly plays a fixing role between the two, so that the structure forms an organic whole.

[0043] In an optional embodiment, the first waterproof layer 700 includes a roof panel, which is fixedly installed above the second waterproof layer 500 via a fixing seat 800.

[0044] Please see Figure 1 In this embodiment, the roof panel is a 0.9mm thick standing seam low-profile roof panel, preferably made of aluminum-magnesium-manganese alloy. The roof panel serves as the first additional waterproof layer at the top, playing a primary role in drainage and waterproofing. Multiple low-profile roof fixing brackets are installed above the second waterproof layer 500. The fixing brackets 800 use stainless steel sliding fasteners to effectively secure the roof panel.

[0045] In an optional embodiment, the second waterproof layer 500 includes a modified bitumen waterproof membrane.

[0046] Please see Figure 1 A 3mm thick SBS modified bitumen waterproof membrane is laid on top of the support layer 400 as the second waterproof layer 500, which works together with the first waterproof layer 700 to achieve the function of drainage and waterproofing.

[0047] In an optional embodiment, an isolation layer 600 is provided between the first waterproof layer 700 and the second waterproof layer 500.

[0048] The isolation layer 600 structurally separates the first waterproof layer 700 from the second waterproof layer 500, ensuring that both waterproof layers are effectively waterproof. It should be noted that the isolation layer 600 can also be omitted between the first waterproof layer 700 and the second waterproof layer 500; that is, the roof panel can be installed directly on top of the second waterproof layer 500, achieving the same drainage and waterproofing function.

[0049] In an optional embodiment, the main structural decorative layer 100 includes, from top to bottom, a fine stone concrete protective layer 110, an extruded polystyrene insulation layer 120, and a concrete roof panel 130, with a waterproof material provided between the extruded polystyrene insulation layer 120 and the concrete roof panel 130.

[0050] Please see Figure 1 The original roof structure, from top to bottom, consisted of a 50mm thick fine aggregate concrete protective layer 110, a 40mm thick extruded polystyrene insulation layer 120, and a prefabricated lightweight concrete roof panel 130. Specifically, a modified bitumen waterproof membrane was installed between the extruded polystyrene insulation layer 120 and the concrete roof panel 130. Because the extruded polystyrene insulation layer 120 was placed on top of the waterproof membrane, the original structure was an inverted roof, resulting in poor waterproofing.

[0051] The construction process of the flexible waterproof roof structure in this embodiment is as follows:

[0052] S1: Lay foam glass insulation boards on the original fine stone concrete protective layer 110 using a special adhesive.

[0053] S2: Install the PCSP metal disc on the foam glass insulation board.

[0054] S3: Lay a 3mm thick SBS modified bitumen waterproof membrane on top of the PCSP metal disc as a second waterproof layer 500.

[0055] S4: Install a low-profile roof fixing bracket above the second waterproof layer 500.

[0056] S5: Install 0.9mm thick standing seam low-profile roof panels. The roof panels serve as the first waterproof layer 700, playing a major role in drainage and waterproofing.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
