Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adiabatic and waterproof roof having excellent heat insulating properties and an excellent waterproof effect.

[0002]

2. Description of the Related Art The roof of a building is required to be waterproof in a snowy region, a region with a large amount of rainfall, or a depopulated area. Above all, a roof of a building in a snowy region is particularly strongly required to have heat insulation and waterproofness. It is rare.

Therefore, conventionally, in order to meet such demands, various upside down construction methods and exposed insulation and waterproof construction methods have been carried out by combining various waterproof layers and various insulation materials, and a roof structure using metal is also used. Although it has been used, its waterproofness is influenced by the workability and is not always satisfactory, and its solution has been strongly desired.

[0004]

However, even in each of the heat insulating and waterproofing methods as described above, for example, in the upside down method, it is necessary to protect the surface side of the heat insulating material with a heavy material such as pressed concrete for durability and wind resistance. There is. Also, in the exposed insulation waterproof method, there is a waterproof layer on the surface side of the heat insulating material,
The waterproof layer does not have sufficient durability and weather resistance due to severe outdoor and annual weather conditions. Therefore, there are problems such as applying a large load to the structure and completely preventing the rain from leaking. Regarding construction, as for the heat insulation and waterproof construction, each material is brought to the construction site, but due to the lack of skilled workers in recent years, etc., there was a rain accident due to a decline in construction technology. Further, the roof made of metal has a defect in the sealing material of the metal joint and the bending process, that is, the goby method, and it is insufficient to completely prevent the rain beam.

The present invention addresses the above situation, aims at a more complete insulation and waterproofing effect, provides a multiple insulation and waterproofing structure on a roof substrate, and finds an improvement in prefabricated structure and joint structure. The purpose is to enhance the heat insulation and waterproof effect of the building, to facilitate the repair of insulation as well as the construction of new buildings, and to promote the ease of on-site construction.

[0006]

That is, one of the features of the present invention which meets the above-mentioned object is that one is a heat insulating material layer, a waterproof layer and / or an adhesive layer on a roof substrate via an adhesive layer,
Next, a heat-insulating waterproof roof structure is provided by providing a metal surface finishing layer, and the other is a structure in which a waterproof layer is further provided between the roof base and the adhesive layer in the roof structure. Further, the present invention is based on the above-mentioned constitution, and is a heat-insulating waterproof roof in which a heat insulating material layer used for the roof, a waterproof layer and / or an adhesive layer on the upper surface thereof, and a metal surface finishing layer are integrally and prefabricated in a desired width and length. It is also characterized by a material (panel), and further characterized in that the heat insulating and waterproof roof and the heat insulating material layer of the roof panel each have a shape in which the thickness is gradually increased so as to form a roof slope.

The present invention is also characterized in that the above-mentioned roof panel joint structure is another feature. All the layer materials are bonded, and the metal plate as the metal surface finish layer has no suspenders and / or a waterproof material. A sealing structure is inserted to form a bent structure, and even between the single plates of the heat insulating material layer is sealed, and when the heat insulating material layer is overlaid twice, the joints of the upper and lower layers are offset and bonded and fixed as brick joints.

[0008]

In the heat-insulating waterproof roof, the waterproof layer is provided on the upper surface of the heat-insulating material layer, and the surface finishing layer made of the metal plate is provided on the surface thereof. Therefore, the waterproofing layer and the metal surface finishing layer provide double waterproofing. In addition to improving the waterproofing effect, the waterproofing layer and the metal surface finishing layer are integrated so that there is no gap, so that water is not invaded, dew condensation or smoldering occurs, and stable waterproofing performance is exhibited. . Moreover, by prefabricating as the panel forming the roof structure, on-site assembly can be facilitated, labor saving in construction and stable quality can be achieved. Further, by inserting a waterproof material and / or a sealing material forming a waterproof layer as a joining means, watertightness is ensured, and water leakage of the roof is reliably prevented.

[0009]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a layered structure 1 of the heat-insulating waterproof roof of the present invention.
For example, FIG. 2 shows one example of the roof forming mode. In the figure, (1) is a roof substrate, (2) is an adhesive layer, (3) is a heat insulating material layer, (4) is a waterproof layer, (5) ) Is a metal surface finish layer.

Here, the roof substrate is made of wood, steel frame, concrete or the like, and the adhesive layer (2) on the substrate (1) is usually made of asphalt, polymer cement or urethane. Further, the heat insulating material layer (3) includes not only foamed synthetic resin heat insulating material such as polystyrene type, urethane type and polyethylene type but also wood wool cement board, siding board, rock wool, glass wool, etc., and is particularly excellent in heat resistance. Those having compressive strength and those having difficulty in absorbing water are preferable, and are formed with a roof slope as shown in FIG. 2 if necessary. Among the foamed synthetic resins as the preferable heat insulating material layer (3), as a heat insulating material having particularly excellent heat resistance, for example, α-methylstyrene was copolymerized with a vinyl monomer containing styrene or acrylonitrile as a main component and foamed. Examples thereof include Heat Max (Kanefuchi Chemical Industry Co., Ltd.), and foam-molded copolymer of styrene and maleic anhydride (Dylark; Sekisui Plastics Co., Ltd.). These heat insulating materials are not particularly susceptible to thermal deformation even when the metal surface finish layer is heated in the midsummer sun, and are therefore particularly preferable in the southern regions where the temperature tends to rise. In addition, a semi-incombustible or incombustible vinyl chloride-based or chlorinated vinyl chloride-based resin foam filled with a large amount of inorganic fibers such as rock wool and calcium carbonate, aluminum hydroxide, etc. (Barillac: manufactured by Kanegafuchi Chemical Industry Co., Ltd. ) And the like are also preferable in places where fireproofness or the like is required, or in necessary parts such as welding.

Next, the heat-insulating material layer (3) is not limited to a single plate made of the above-mentioned material laid out in a plane and may be a stack of a large number of single plates. In this case, the single plates are sealed. (6)
In addition, the joints can be shifted above and below the single plate as shown in FIG. Further, it is also preferable to provide a groove on the lower side of the heat insulating material so that the structure can be ventilated to prevent water absorption into the heat insulating material.

As the waterproof layer (4) on the upper surface of the heat insulating material layer (3), any of asphalt roofing, synthetic polymer sheet, coating film, etc. can be used, but especially synthetic fiber nonwoven fabric is modified with synthetic rubber. Asphalt roofing in which a large amount of asphalt is impregnated and coated is extremely effective, and among them, the one having self-adhesiveness is particularly preferable in terms of adhesion with the metal surface finishing layer (5). For the metal surface finishing layer (5), generally, any metal plate such as stainless steel, aluminum plate, and surface-treated steel plate defined by JASS12 roof construction specifications can be applied. Further, it is also possible to reduce the change due to expansion and contraction due to heat by providing unevenness on the back surface of the metal plate or providing convex portions on the metal layer.

An adhesive or a pressure-sensitive adhesive is applied to the waterproof layer (4) in advance, release paper is temporarily attached, and the release paper is peeled off for the construction, and the heat insulating material layer (3) or the metal surface finishing layer (5). It is advantageous in terms of work to bond with.
Although not shown, a waterproof layer may be further provided between the roof substrate (1) and the adhesive layer (2) on the upper surface thereof, and in this case, the waterproof layer is the same as the waterproof layer (4). Asphalt roofing can be used.

Further, in the above-mentioned layer structure, the heat insulating material layer (3), the waterproof layer (4) on the upper surface thereof and the metal surface finishing layer (5) are integrated as a laminated product having a required width and length to form a prefabricated structure. Can be kept. In this case, it is easier to carry this laminated product to the site, assemble each prefabricated panel on the site, and after the assembly, perform rain punishment on the ends of the joints, eaves, ridges, etc. Construction is possible. The required length and width are preferably, for example, the length and width that can be loaded on the transportation means, and can be freely set according to the purpose.

The layer structure of the roof constructed as described above usually uses a fixing end plate portion which is one end of a metal plate which is a metal surface finishing layer (5) and a fixing end plate portion on the other side. , A heat-insulating double waterproof roof is formed by joining one fixing end plate part and the other fixing end plate part of the metal plates adjacent to each other, but in this case, no suspenders are used. A watertight structure is adopted by adhesion.

FIG. 4 shows one of the layer configurations of the roof, and FIG.
Reference numerals 6, 7 and 8 are examples of joining modes. That is, FIG. 5 shows a mode in which one fixing end portion and the other fixing end portion of the adjacent metal surface finishing layer (5) are joined via the seal material (7), and FIG. 6 is further bent laterally. The mode which inserted the sealing material (7) between both is shown. In this case, an asphalt roofing sheet which is the waterproof layer (4) on the upper surface of the heat insulating material layer (3) may be bent and used as the sealing material (7), or another sealing material may be inserted.

Further, it is more effective to use one fixing end portion for the joint portion as shown in FIGS. 7 and 8 and cover it with another covering material (8). The sealing material (7) is a reaction hardening type metal surface finishing layer (5).
It is desirable that the strain of change due to heat between the waterproof layer (4) and the waterproof layer (4) can be relaxed. Further, in FIG. 7, one side of the waterproof layer (4) is stretched in a state where the heat insulating material (3) and the waterproof layer (4) are bonded, and the waterproof sheets are lap-joined at the time of construction on site. The lap joining position is preferably between the different coating materials (8) at the joining portion of the metal finishing layer (5).

[0019]

As described above, the present invention is a heat-insulating waterproof roof in which a heat-insulating material layer, a waterproof layer, and then a metal surface finishing layer are sequentially laminated on the roof substrate through an adhesive layer. In addition to having a waterproofing effect due to the finishing layer, they both exhibit stable performance as a roof waterproofing without water intrusion and dew condensation, and a prefabricated heat insulating material layer, upper waterproofing layer and metal surface finishing layer. By adopting this, not only new construction but also renovation of heat insulation and waterproofing on the existing waterproof roof becomes easy, and good workability can be achieved.
In addition, the layered structure of the roof according to the present invention does not damage the waterproof layer because the laminated material is entirely layered by adhesion without using fixing means penetrating the layers, and each of the metal surface finishing layers forms a waterproof layer. By inserting a waterproofing material and / or a sealing material, which is additionally used, and by adopting a joint structure that is bent, a higher degree of water-tightness is made possible, so that intrusion of water can be prevented more reliably. . Further, in the conventional flat roof structure, the roof base is provided with a slope, but in the present invention, the roof base is horizontal, and since a sloped roof can be easily formed only by providing a slope to the heat insulating material layer, labor saving is achieved. It is extremely economically advantageous. Further, even when the slope of the roof base is gentle, by adopting a heat insulating layer with a slope, it is possible to form a sloped roof having a higher drainage property. The present invention not only has a heat insulating effect but also a drainage property of the roof. Combined with the double waterproof effect, the waterproof performance is further enhanced.
It is expected to be very effective as a roof structure in snowy regions, areas with high rainfall, or depopulated areas.
