Description

Technical Field

[0001] This utility model relates to the field of waterproofing technology, and in particular to a fused tile that combines waterproof membrane and metal plate in sections. Background Technology

[0002] Because the new waterproofing standard for metal roofs, "General Specification for Waterproofing of Buildings and Municipal Engineering" (GB 55030-2022), has higher waterproofing requirements than before, metal roofs require two layers of waterproofing, except for Class B projects in Class III waterproofing environments and Class C projects in Class II and Class III waterproofing environments. To meet this requirement, fused tiles can effectively solve the need to complete two layers of waterproofing in one process. Fused tiles are made of metal sheets and waterproof membranes such as TPO or PVC. The existing method of using fused tiles involves nailing the fused tile to the purlin, with the nail penetrating both waterproofing layers at the same time. Then, a cap made of the same material as the roofing membrane is used to wrap the nail and heat-melt weld it to the surface membrane. The cap is equivalent to a layer of waterproofing. The existing method loses the integrity of the two layers of waterproofing of fused tiles. Utility Model Content

[0003] The technical solution of this utility model to solve the above-mentioned technical problems is to provide a fused tile that is composited with a waterproof membrane and a metal plate in sections, including a metal substrate and a waterproof membrane layer. The metal substrate is formed with alternating wave crest planes and wave base regions along its width direction. The waterproof membrane layer is pre-laminated on at least one of the wave crest planes in the factory to form a factory composite area, and an overlap edge is reserved at the edge of the waterproof membrane layer. At least one of the wave base regions is a non-composite area where the waterproof membrane layer is not composited. The overlap edge constitutes a field bonding area for on-site bonding with the factory composite area of ​​adjacent fused tiles.

[0004] Furthermore, a male buckle is provided on one side of the metal substrate, and a female buckle that mates with the male buckle is provided on the other side.

[0005] Furthermore, the factory composite area is located on the first crest plane near the male buckle.

[0006] Furthermore, the waterproof membrane layer is a TPO waterproof membrane or a PVC waterproof membrane.

[0007] Compared with existing technologies, the fused tile structure of waterproof membrane and metal plate segmented composite provided by this utility model and its installation method have the following significant advantages:

[0008] 1. Completely ensures the integrity and independence of the double waterproof layer, significantly improving waterproof reliability:

[0009] The core advantage of this invention lies in its unique "segmented composite" structural design (composite at the crest, non-composite at the base) combined with a "non-penetrating" fixing and installation process, which completely avoids damage to the flexible waterproof membrane layer caused by fasteners (such as screws and rivets). In traditional fused roof tile installation methods, fasteners need to penetrate both the metal plate and the waterproof membrane, compromising the integrity of the double waterproofing layer. Remedial sealing relies solely on subsequent caps, creating a risk of leakage. In this invention, the first rigid waterproofing layer is provided by the metal plate itself, secured by waterproof rivets at the base, ensuring reliable sealing at the rivet holes. The second flexible waterproofing layer is provided by a complete, undamaged TPO / PVC waterproof membrane layer. These two independent yet synergistic layers form a truly complete double waterproofing system, significantly improving the reliability and durability of the roof's waterproofing and better meeting the high standards of the "General Specification for Waterproofing of Buildings and Municipal Engineering" (GB55030-2022).

[0010] 2. Extend the lifespan of the roofing system and reduce total lifecycle costs:

[0011] Because the flexible waterproof membrane layer has no perforations, its physical and chemical properties (such as tensile strength, aging resistance, and corrosion resistance) are fully preserved, avoiding the risk of material tearing or accelerated aging caused by stress concentration at perforations. Simultaneously, the on-site overlap edges are hot-air welded, achieving a connection strength of over 80% of the base material's strength, forming a robust, integrated seal far exceeding the sealing effect of ordinary adhesives. This results in a longer maintenance cycle for the entire roofing system, significantly reducing later repair and replacement costs, and offering superior economic efficiency from a life-cycle perspective.

[0012] 3. Construction is more standardized, efficient, and quality is more controllable:

[0013] This solution brings some processes to the factory in advance, ensuring the uniformity and high quality of the bonding between the metal sheet and the waterproof membrane in the corrugated area, and reducing variables during on-site construction. During on-site installation, the process is clear and straightforward: first, the metal substrate is mechanically fixed, then the overlap of the waterproof membrane is addressed. This streamlined operation reduces construction difficulty and over-reliance on worker skill levels, improves installation efficiency, and makes it easier to ensure the consistency and reliability of the final construction quality.

[0014] 4. Strong structural safety and wind uplift resistance:

[0015] By employing specialized fasteners and male interlocking clips, along with waterproof rivets for multiple mechanical locking mechanisms, a robust, concealed connection node is formed. This connection method offers higher tensile strength and wind uplift resistance than traditional exposed nail and screw fixing, making it particularly suitable for the roofs of large public buildings in areas prone to strong winds and heavy rains, ensuring the safety of the building envelope.

[0016] 5. Significant economic and social benefits:

[0017] This invention achieves two high-performance waterproofing layers in a single process, simplifying the traditional two-step process of applying metal panels and waterproof membranes separately, thus saving labor, machinery, and time costs. Simultaneously, its superior waterproofing performance effectively protects the building's internal structure and assets, reducing social disputes and quality problems caused by leaks, and thus yielding positive social benefits.

[0018] In summary, this utility model not only solves the fundamental defect of existing fused tile waterproofing layers being penetrated at the technical level, but also provides comprehensive optimization in terms of economic benefits, construction convenience, and long-term reliability. It is a new type of building material product that meets market development trends and high-standard waterproofing requirements. Attached Figure Description

[0031] Example 1:

[0032] In the technical solution of this embodiment, such as Figure 1 , Figure 2 As shown, a fused tile composed of a waterproof membrane and a metal plate in segments is provided, including a metal substrate 1 and a waterproof membrane layer 2. The metal substrate 1 is formed with alternating wave crest planes 11 and wave base regions 12 along its width direction.

[0041] S4: Apply special adhesive to the bonding surfaces of the second fusion tile in the factory bonding area 3 and / or the field bonding area 5 of the first fusion tile.

[0042] S5: Lay and bond the pre-reserved overlap edge 21 of the first fusion tile to the waterproof membrane layer 2 of the factory composite area 3 of the second fusion tile to form an overlap area, and seal the overlap area by hot air welding.

[0043] S6: Repeat steps S2 to S5 to install subsequent fusion tiles in sequence.

[0044] Furthermore, in step S3, the waterproof sealing treatment involves covering the head of the waterproof rivet 8 with butyl tape or sealant.

[0045] Furthermore, in step S5, hot air welding involves using a hot air welding gun to heat-melt and fuse the upper and lower layers of waterproof membrane in the overlapping area into a whole.
