Description

Technical Field

[0001] This invention relates to the field of roof plan technology, and more particularly to a roof layer structure. Background Technology

[0002] A roof is the load-bearing and enclosing component at the top of a building, generally consisting of three parts: the roof surface, the insulation (heat insulation) layer, and the load-bearing structure. A flat roof, on the other hand, has a very gentle slope, a height-to-span ratio of less than 1 / 10, and a generally flat surface, allowing for pedestrian access and activity. Some flat roofs can even serve as roof gardens or helipads. A flat roof comprises a load-bearing structure, functional layers, and the roof surface. The load-bearing structure is typically composed of reinforced concrete beams (or trusses) and slabs. The functional layers, besides waterproofing which is handled by the roof surface, vary depending on the region. For example, cold regions require an insulation layer, while hot regions require a heat insulation layer. This patent provides a roof structure that is both insulated and waterproof. Summary of the Invention

[0003] To address the aforementioned problems, this invention discloses a roof layer structure, comprising, from bottom to top: a cast-in-place layer, a concrete slope-finding layer, a concrete leveling layer, an asphalt coating, a first asphalt waterproof membrane, a foam board, a first cement mortar bonding layer, a second asphalt waterproof membrane, a non-woven fabric layer, a concrete protective layer, another second cement mortar bonding layer, and imitation stone tiles. The presence of the first and second asphalt waterproof membranes ensures the roof's waterproof performance, while the foam board provides insulation. Furthermore, the foam board's location between the first and second asphalt waterproof membranes ensures its dryness.

[0004] Preferably, metal strips are snapped onto both the first and second asphalt waterproof membranes, and cement nails protrude from the metal strips. The first and second asphalt waterproof membranes are then secured together using the metal strips and cement nails.

[0005] Preferably, the thickness of the thinnest part of the concrete slope-finding layer is 30mm.

[0006] Preferably, the thickness of the concrete leveling layer is 20mm.

[0007] Preferably, the thickness of the foam board is 100 mm.

[0008] Preferably, the thickness of the first cement mortar bonding layer is 20 mm, and the thickness of the second cement mortar bonding layer is 15 mm.

[0009] Preferably, the concrete protective layer is 40mm thick and has 20mm wide gaps spaced equidistantly in both directions, which are filled with sealant. The sealant is polyurethane, and the gaps in the concrete protective layer are designed to prevent stress and damage during thermal expansion and contraction.

[0010] The beneficial effects of the present invention are as follows: the provision of a first asphalt waterproof membrane and a second asphalt waterproof membrane ensures waterproof performance, and the foam board located between the first asphalt waterproof membrane and the second asphalt waterproof membrane plays a role in heat insulation.

[0014] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0015] like Figure 1 As shown, a roof structure comprises, from bottom to top, a cast-in-place layer 1, which is the main structure of the building and contains pre-reinforced steel reinforcement; a concrete leveling layer 2, which, after the cast-in-place layer 1 has cured, has a slight slope on its upper surface; the concrete leveling layer 2, made of LC7.5 lightweight aggregate concrete, is laid to improve the surface smoothness; a concrete leveling layer 3, which further improves the surface smoothness, made of DS20 cement mortar; an asphalt coating 4, specifically a non-curing rubber asphalt waterproof coating that does not flow at 90°C; and a first asphalt waterproof membrane 5. The asphalt coating 4, to a certain extent, protects the first asphalt membrane from water. The waterproof membrane 5 is used for fixing. Foam board 6 provides insulation and is made of extruded polystyrene foam. The first cement mortar bonding layer 7 is used to bond and fix the upper and lower layers. The material used is DS20 cement mortar. The second asphalt waterproof membrane 8 serves a waterproof function. The non-woven fabric layer 9 and the concrete protective layer 10, made of C20 fine stone concrete, protect the underlying structure. The second cement mortar bonding layer 11, made of DS15 cement mortar, bonds and fixes the upper and lower layers. The imitation stone bricks 12 serve a decorative function and improve the overall aesthetics of the roof.

[0016] Metal strips are snapped onto the first bitumen waterproof membrane 5 and the second bitumen waterproof membrane 8, and cement nails protrude from the metal strips. Cement nails and metal strips are the main fixing methods for the first bitumen waterproof membrane 5 and the second bitumen waterproof membrane 8. The cement nails on the first bitumen waterproof membrane 5 are inserted and fixed in the concrete leveling layer 3, while the cement nails on the second bitumen waterproof membrane 8 are inserted and fixed in the first cement mortar bonding layer 7.

[0017] Furthermore, the non-woven fabric layer 9 is pressed under the metal strip, and during the construction of the concrete protective layer 10, the second asphalt waterproof membrane 8 and the concrete protective layer 10 are integrated under the action of the non-woven fabric layer 9.

[0018] The thinnest part of the concrete slope-finding layer 2 is 30mm thick.

[0019] The thickness of concrete leveling layer 3 is 20mm.

[0020] The thickness of foam board 6 is 100mm.

[0021] The thickness of the first cement mortar bonding layer 7 is 20mm, and the thickness of the second cement mortar bonding layer 11 is 15mm.

[0022] The concrete protective layer 10 is 40mm thick and has 20mm wide gaps spaced equidistantly in both directions. These gaps are designed to prevent the concrete protective layer 10 from being damaged by thermal expansion and contraction. The gaps are filled with sealant.

[0023] The technical means disclosed in this invention are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features.
