Description

Technical Field

[0001] This application relates to the field of waterproof structures, and more specifically, to a waterproof roof structure. Background Technology

[0002] With the rise of the outdoor economy, small mobile homes with a technologically advanced and stylish appearance and comfortable living conditions are gaining popularity. These products are custom-made in factories, hoisted on-site, and ready for use once water and electricity are connected. The roof material is aluminum panels, which are fixed to the main keel with corner brackets. The edges between the aluminum panels are sealed with silicone weather-resistant sealant. Later, due to their own weight, the aluminum panels sag, creating concave areas where water and dust accumulate. The larger the span, the more serious the water accumulation. The sealant joints between the panels are heavily dependent on the installer's skill. Inadequate cleaning of the construction surface, insufficient sealant thickness, blistering of the sealant, poor overlap between construction sections, or aging of the sealant can all cause roof leaks, affecting usability and requiring frequent maintenance. Summary of the Invention

[0003] The purpose of this application is to provide a waterproof roof structure that can solve the above-mentioned technical problems.

[0004] This application provides a waterproof roof structure, including a roof joists and an aluminum plate layer. The roof joists are provided with a left support joist and a right support joist. Upper aluminum plate fasteners are provided on the left support joists and the right support joists. The aluminum plate layer has downwardly extending upper aluminum plate folded edges at both ends. The upper aluminum plate folded edges are fixed to the upper aluminum plate fasteners by bolts. An OSB structural layer is provided at the lower end of the roof joists. A polyurethane foam insulation layer is filled between the OSB structural layer and the aluminum plate layer.

[0005] Preferably, the aluminum plate layer includes multiple upper aluminum plates, and two adjacent upper aluminum plates are interlocked and fixed by U-shaped grooves provided at their ends.

[0006] Preferably, a central support keel is provided between the roof keel and the aluminum plate layer. Multiple central support keels can be provided, and the central support keels are provided at the intersection of two upper aluminum plates.

[0007] Preferably, the aluminum plate layer is arranged with a high center and low sides, and lower aluminum plates are provided at both ends of the aluminum plate layer. The lower aluminum plates are fixed to the two ends of the aluminum plate layer by bolts.

[0008] Preferably, the roof joists are hollow.

[0009] Preferably, the OSB structural layer is fixed to the roof joists by means of nails.

[0010] Preferably, the thickness of the OSB structural layer is 0.5-5cm, and the thickness of the polyurethane foam insulation layer is 2-30cm.

[0011] The beneficial effects of this utility model are:

[0012] This utility model provides a waterproof roof structure, including a roof keel and an aluminum plate layer. The roof keel has a left support keel and a right support keel, with upper aluminum plate fasteners on the left and right support keels. The aluminum plate layer has downward-extending upper aluminum plate flanges at both ends, which are fixed to the upper aluminum plate fasteners by bolts. An OSB structural layer is located at the lower end of the roof keel, and a polyurethane foam insulation layer fills the space between the OSB structural layer and the aluminum plate layer. This utility model fills the cavity formed between the aluminum plate layer and the OSB board on the lower surface of the roof keel with flame-retardant polyurethane foam. The aluminum plate layer, the polyurethane foam insulation layer, and the lower OSB board form a spatial composite structure. This completely solves the problem of water and dust accumulation caused by the top aluminum plate sinking due to its own weight. The composite structure also improves the overall sealing of the structure, significantly reducing the noise interference from raindrops hitting the upper aluminum plate during rainy days, and greatly reducing the after-sales risks caused by roof leaks during later operation.
