本考案は難燃性防水シート構造に係り、詳しく

上に敷設する難燃性防水シート構造に関する。[Detailed Description of the Invention] The present invention relates to a flame-retardant tarpaulin sheet structure, and more particularly to a flame-retardant tarpaulin sheet structure to be laid on a subsurface such as a flat roof, a pitched roof, or a curved roof.

い欠点があつた。 In recent years, there has been a particularly strong trend towards making waterproof layers on roofs non-combustible, and some prefectures have enacted ordinances.
Materials and construction methods are being carefully selected, and this trend is spreading nationwide. The waterproofing layer commonly used here is flammable because it is mostly composed of organic compounds, and even if it is possible to make it flame retardant by design, it is completely non-flammable. It is very difficult to do so. For this reason, structures were adopted in which mortar was poured as a protective material on top of the waterproof layer, and structures in which gravel was laid down, but in the case of pouring mortar, if water leaks, the waterproof layer cannot be seen from the outside, so water leaks. It is difficult to inspect and inspect each location, and removing the mortar layer during repair requires a great deal of labor and labor.Furthermore, the thickness of the mortar layer is required to be at least 50 mm per square meter of the roof . The weight of the building increased and the structure of the building was limited. Particularly, it has the disadvantage that it cannot be applied to sloped roofs, curved roofs, etc., which have recently been designed with emphasis on exterior design.
このような構造の欠点を改善したものとして、

し着火する場合があつた。 In order to improve the shortcomings of such a structure,
It has been proposed that a colored decorative inorganic fire-retardant finishing material (for example, one containing silica and inorganic filler as the main ingredients) is layered on a waterproof sheet, but such an inorganic fire-retardant finishing material is Since there is almost no elongation during cutting, if the tarpaulin layer swells due to the thermal expansion of the air or water vapor existing between the tarpaulin sheet and the base due to the heat generated by the combustion body, it will cause only a slight bulge. The waterproof sheet also cracked easily, and there were cases where the waterproof sheet was exposed through the cracks and caught fire.

ート構造となる。 The present invention improves the above-mentioned drawbacks, and in particular makes waterproof sheets installed on roof bases of various shapes flame-retardant. The purpose of this is to provide a waterproof sheet structure that does not easily crack even when it swells and has excellent flame retardancy by preventing gaps between protective layers from forming. The gist is that the waterproof sheet layer consists of only a base material, or the surface of the base material is coated with a fire-retardant finish layer, and a ceramic board with a thickness of 4 to 25 mm is laid without gaps as a protective material on the surface of the waterproof sheet layer. Even if the tarpaulin layer tends to swell due to the thermal expansion of the air or water vapor existing between the base and the tarpaulin layer due to the heat generated by the combustion body, the surface of the tarpaulin layer Since each of the multiple ceramic plates installed has a certain weight, it prevents the waterproof sheet layer from swelling, and even if there are gaps between the ceramic plates, a waterproof finishing layer can be applied to the base material and laminated. By using a waterproof sheet, it becomes a flame-retardant waterproof sheet structure that prevents ignition of the base material.

On the other hand, FIG. 2 is a longitudinal cross-sectional view of a flame-retardant waterproof sheet structure 1 which is a modified embodiment of the present invention, and the waterproof sheet layer 3 is constructed by coating and laminating a fire-retardant finishing layer 5 on the base material 2. The ceramic plate 4 is laid on the fireproof finish layer 5 without any gaps.

生じやすくなる。 The waterproof sheet layer 3 is one of the base materials 3 or a fireproof finish layer 5 laminated on the base material 2, and the base material 2 is made of vulcanized rubber or non-vulcanized rubber, which are generally used as waterproof materials. , or thermoplastic elastomer, etc., and the materials are EPDM, IIR, CR,
A single substance such as CSM or a blend thereof may be used, and rubberized asphalt may also be used, and the fireproof finish layer 5 is composed of an organic binder and an inorganic aggregate. Organic binders include acrylic resin, urethane resin, epoxy resin, vinyl chloride resin, and ethylene vinyl acetate resin for resin type, EPDM, IIR, CR, and CSM for rubber type, and toluene, xylene, n-hexane, cyclohexane, etc. for emulsion type. It can also be used in a type diluted with a solvent, while inorganic aggregates such as silica sand, kansui stone sand, glass flakes, glass balloons, perlite, crushed natural stone, crushed ceramic granules, etc. can be used in amounts of 50 to 300 parts by weight per 100 parts by weight of the organic binder. If it is less than 50 parts by weight, the combustible components of the organic binder will be too strong and sufficient flame retardancy cannot be maintained.
If it exceeds 300 parts by weight, the content ratio of the organic binder decreases, the elongation rate of the fireproof finish layer upon cutting decreases, and cracks are likely to occur due to blistering of the waterproof sheet layer 3.

しない。 However, the total thickness of this waterproof sheet layer 3 is
A suitable value is 0.5 to 3.0 mm, and if it is less than 0.5 mm, the impact resistance will be poor, while if it is less than 3.0 mm, the difference in level between the joints of the waterproof sheets will become large and the unevenness of the ceramic layer will become noticeable. In addition, when installing it on a roof base, it can be bonded with a normal adhesive, such as a chloroprene adhesive, and no special treatment is required.

格も高くなる。 Further, from the viewpoint of heat resistance and weather resistance, the ceramic plate 4 is preferably made of silicon dioxide (silica) or aluminum oxide (alumina), but of course, there is no problem in using general ceramic tiles. Moreover, since it can be easily colored, it can also exhibit excellent cosmetic properties. The appropriate thickness of this ceramic plate 4 is 4 to 25 mm, and if it is less than 4 mm, it will easily break.
In addition, the weight becomes smaller and corresponds to the bulge of the waterproof sheet layer 4, which deteriorates the heat resistance effect.
If it is more than mm, the weight will be large, resulting in poor workability and high price.

に限定されない。 The base material 2 of the waterproof sheet layer 3 or the fireproof finish layer 5 and the ceramic plate 4 can be easily bonded using double-sided tape, adhesive rubber tape, or ordinary adhesive. If the amount is small, it is not necessarily necessary to bond. In addition, there is no limit to the size of ceramics, but in consideration of workability and aesthetics, 10mm x 10mm
Preferably 10mm to 300mm x 300mm. Of course, it is not limited to square shapes.

ともできる。 Thus, the flame-retardant waterproof sheet structure 1 is waterproof even if the waterproof sheet layer 3 attempts to swell due to the thermal expansion of the air or water vapor existing between the base and the waterproof sheet layer 3 due to the heat generated by the combustion body. Since the plurality of ceramic plates 4 laid on the surface of the sheet layer 3 have an appropriate weight, the waterproof sheet layer 3 is prevented from swelling and gaps between the ceramic plates 4 are suppressed. Even if there are gaps between the ceramic plates 4, the base material is coated with a stretchable fireproof finish layer 5 having a composition in which inorganic aggregate is dispersed in an organic binder. By using the coated and laminated waterproof sheet layer 3, it is possible to further prevent ignition of the base material 2, and not only that, but also the fireproof finish layer 5 expands to follow the behavior of the base material that is about to swell. Since the base material 2 does not cause any cracks, it has the function of almost completely preventing ignition of the base material 2. Furthermore, since the ceramic plates 4 laid on the surface of the waterproof sheet layer 3 are not bonded to each other, the waterproof sheet structure of the present invention is highly flexible and has excellent portability and workability. Further, by adding various colorants to the ceramic plate 4, it is possible to form a flame-retardant waterproof sheet structure with a decorative effect.
