Description

Technical Field

[0001] This invention relates to the field of roof building engineering technology, specifically to a prefabricated integrated system for roof insulation, waterproofing, and decoration. Background Technology

[0002] As the core building envelope that directly contacts the outdoor environment, the roof's thermal insulation, waterproofing, and aesthetic performance directly determine the building's comfort, energy consumption, and overall lifespan, making it a crucial functional element in building construction. Currently, the mainstream roof construction techniques are mainly divided into two categories: upright and inverted. Upright roofs require multiple steps in sequence, including leveling or slope creation layer, vapor barrier, insulation layer, leveling layer again, two or more waterproofing layers, isolation layer, and protective layer. Inverted roofs, on the other hand, follow the construction sequence of leveling or slope creation layer, two or more waterproofing layers, insulation layer, and protective layer. However, in traditional roof construction methods, the three main functional modules—insulation, waterproofing, and decoration—are designed and constructed independently on-site, resulting in numerous insurmountable technical drawbacks: First, the complex procedures and numerous connection points make the interface treatment between different processes prone to creating weak points, easily leading to leaks, insulation failure, and other hidden dangers. Second, the construction process is highly dependent on the on-site working environment; natural climatic conditions such as rain, snow, and temperature and humidity fluctuations directly affect the construction progress and project quality, leading to delays and poor quality stability. Third, the large amount of on-site wet work results in high manual labor intensity, low efficiency, and significant material waste, making it difficult to effectively control construction costs. Fourth, traditional techniques cannot adapt to the development trend of modern building industrialization and prefabrication, failing to meet the demands for efficient construction and high-quality delivery. These problems have long plagued the roof engineering field, urgently requiring an integrated, prefabricated solution to overcome them. Summary of the Invention

Furthermore, the rationally designed, height-adjustable, and easily assembled elevated structure further enhances the system's adaptability. Attached Figure Description

The third joint additional roll 444 is set on the adjacent polymer waterproof rolls 44 and fixedly welded to them to form a reliable waterproof.

[0037] In a preferred embodiment, a protective layer 6 may be provided on the polymer waterproof membrane 44. The protective layer 6 can be provided in two ways: one is to directly use a waterproof membrane with a built-in protective layer 6; the other is to provide the protective layer 6 on the integrated thermal insulation and waterproofing board 4.

[0038] In a preferred embodiment, the insulation board 41 is selected from any one of extruded polystyrene board, polyurethane board, phenolic board, and rock wool board.

[0039] In a preferred embodiment, the inorganic board 43 is a UHPC board or a high-density fiber cement board.

[0040] In a preferred embodiment, the polymer waterproof membrane 44 is a weldable thermoplastic material, such as EPDM rubber, polyvinyl chloride, thermoplastic polyolefin membrane, or high-density polyethylene membrane. The membranes are connected by welding and have a thickness of at least 1.2 mm.

[0041] In a preferred embodiment, the integrated thermal insulation and waterproofing panel 4 can be installed on-site using mortar or foam adhesive, or mechanically fixed using connecting brackets.

[0042] In a preferred embodiment, the decorative layer 5 is made of lightweight and high-strength composite material, such as polypropylene honeycomb composite board, fiberglass honeycomb composite board, or polyurethane pultruded board.

[0043] refer to Figure 12-16 As an optimized technical solution, the roofing system also includes a raised floor 7, which can be installed above or below the integrated thermal insulation and waterproofing panel 4, and includes adjustable supports 71 and keel 72. The adjustable supports 71 are laid on the lower structural layer, and the keel 72 is fixedly installed on the upper part of the adjustable supports 71 by fixing clips 73.

[0044] In a preferred embodiment, the keel 72 is a square tube frame; the adjustable support 71 includes a lower support 711 and an upper support 712. A first connecting steel pipe 713 is provided on the upper side of the lower support 711, and a second connecting steel pipe 714 is provided on the lower side of the upper support 712. The two are connected by threads to achieve height adjustment; a first threaded hole is opened on the upper end face of the upper support 712. The fixing clip 73 is a straight-line or cross-shaped clip, with a second threaded hole passing through its middle. The fixing bolt 74 passes through the second threaded hole and the first threaded hole on the adjustable support 71 in sequence to fix the fixing clip 73 to the adjustable support 71. The ends of each keel 72 are engaged in the slots of the fixing clip 73, and the ends of the keels 72 are provided with threaded holes corresponding to the slots, and are tightened by connecting nuts 75. This elevated floor 7 structure is simple to assemble, has strong integrity, and can flexibly adjust its height according to the flatness of the base layer and design requirements, showing good adaptability.

[0045] In practice, the leveling layer 2 is first constructed on the roof structural layer 1, followed by the application or laying of a waterproof coating layer 3. This waterproof coating layer 3 serves as both an independent waterproof layer and a vapor barrier, effectively preventing indoor moisture from penetrating the insulation layer.

[0046] Pre-fabricated integrated thermal insulation and waterproofing panels (assembly units 4) are transported to the site. Each assembly unit consists of a bottom insulation board 41, a middle adhesive layer 42, an inorganic board 43, and a surface polymer waterproof membrane 44. Several assembly units are installed and spliced ​​according to the roof dimensions. Waterproofing is achieved between adjacent assembly units using pre-designed connection points 45. For example, adjacent polymer waterproof membranes 44 are welded and overlapped on the pre-designed first corner edge 431 of the inorganic board 43, or the membrane's own joint 441 is fitted into the second corner edge 432 and welded for fixation, or additional seam membrane 442 is laid for sealing. The insulation layer beneath the unit panel can be bonded to the structural base layer using matching mortar or foam adhesive, or mechanically anchored using connecting brackets to ensure stable installation.

[0047] If the design includes an elevated layer 7, adjustable supports 71 can be laid on the integrated insulation and waterproofing panel 4 after installation. The threaded steel pipes between the upper and lower supports are rotated to adjust to the design elevation. Then, the fixing clips 73 are bolted to the upper end of the supports. Next, a square tube frame is erected, its ends inserted into the slots of the fixing clips 73 and locked, forming a well-integrated, smooth elevated frame. Finally, polypropylene honeycomb composite panels or other panels are laid on the frame as a decorative layer, completing the prefabricated construction of the entire roofing system.
