Description

[Technical field]

[0001] The utility model relates to the technical field of building construction, in particular to a positive roofing system using polyurethane foam as a thermal insulation layer. [Background technology]

[0002] The upright roof is a roof structure in which the waterproof layer is above the insulation layer. Many technicians believe that the waterproof layer above the insulation layer is prone to human damage, water enters the insulation layer, and finally leads to reduced energy-saving effects. With the improvement of national construction technology, the "General Specification for Waterproofing of Buildings and Municipal Engineering" GB55030-2022 has also been issued and implemented. The design service life of roofing engineering waterproofing should not be less than 20 years. In order to meet the needs of national development, the utility model proposes a new upright roof structure. [Contents of the utility model]

[0003] The technical problem to be solved by the utility model is to provide a positive roof system which adopts polyurethane foam as the thermal insulation layer. The reasonable structure has not only excellent energy-saving and waterproof effects, but also has the advantages of light load and high strength, and can reduce noise in the rainy season. In addition to flat roofs, it can also be constructed on curved roofs, special-shaped roofs, steel structures or wooden structures, and has strong plasticity.

[0006] The thickness of the polyurethane foam insulation layer is 20 mm to 80 mm;

[0007] The thickness of the interface treatment layer is 0.1 mm to 0.5 mm;

[0008] The thickness of the slope and leveling layer is 5mm to 50mm;

[0009] The thickness of the waterproof layer is 2.5-3.2 mm.

[0010] Furthermore, the roof structure layer is a concrete structure roof, a steel structure roof, or a wooden structure roof.

[0011] Furthermore, the upper surface of the roof structure layer is a flat surface, a curved surface, a sloping roof or a special-shaped surface.

[0012] Furthermore, the interface treatment layer adopts a waterproof emulsion coating.

[0013] Furthermore, the slope and leveling layer is a foam concrete layer or a cement mortar layer.

[0014] Furthermore, the number of the waterproof layers is 1 to 3, and the waterproof layers include, from bottom to top, a polymer cement adhesive material layer with a thickness of 1.3 to 2 mm and a polymer composite waterproof roll material layer with a thickness of 1.2 mm.

[0015] Furthermore, a polymer waterproof coating layer with a thickness of 1.5 mm is provided between the waterproof layer and the protective layer.

[0016] Furthermore, the protective layer is a tile, or a mortar layer with a thickness of 5 to 30 mm, or a reinforced concrete layer with a thickness of 30 to 40 mm.

[0017] The advantages of the utility model are:

[0018] The upright roof system adopts polyurethane foam material with low density and thermal conductivity and easy construction as the insulation layer of the upright roof, with good energy-saving effect, no need to consider the influence of water entry on the energy-saving effect of the inverted type, and light weight and thin thickness (for the same energy-saving effect, foam concrete requires 5 times the thickness of polyurethane foam material); not only the energy-saving and waterproof effect of the roof is improved, but also the construction adaptability of the insulation material is improved, the load is low, the labor cost is low, the efficiency is high, and the quality is reliable.

[0019] In short, the utility model has a reasonable structural setting and not only has excellent energy-saving and waterproof effects, but the entire roof structure also has the advantages of light load and high strength, and can reduce noise in the rainy season; because the polyurethane foam material can be sprayed and foamed according to the various shapes of the roof structure layer during laying to form an insulation layer with a smooth upper surface, it is not only suitable for roof structure layers with a flat surface, but also suitable for the repair of special-shaped roof structure layers with irregular upper surfaces such as curved, wavy, folded surfaces, or steel structure roofs or wooden structure roofs.
