[0002]

2. Description of the Related Art Conventionally, painted metal sheets have been used for roof tile roofs and the like, but repairs and repairs such as repainting and water leakage prevention have been performed every several years for the purpose of preventing corrosion.

[0003] As a repair method for providing long-term durability,
There is a method of bonding a rubber-based waterproof sheet or a vinyl chloride resin-based waterproof sheet to a foundation (existing tile rod roof). However, according to this method, when applying the adhesive and applying the waterproof sheet along the shape of the roofing rod, the waterproof sheet is adhered while bending the side edge of the waterproofing sheet along the existing roofing rod. There is a problem in that the workability is poor such as difficulty in wrinkling and easy formation of wrinkles, and furthermore it takes much man-hour.

In order to maintain the waterproof performance of the roofing bar, it is usual to raise both sides of the metal plate and roll the ends of the roofing bar at the head of the roofing bar. The roof of the roofing bar is not flat.
There were also disadvantages in the design finish such as bonding strength, sag, and dent.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiments of the present invention will be described in further detail with reference to the drawings. As a repair method, firstly, both sides of the waterproof sheet A to be used are subjected to bend processing in advance, and rising joints 2 and 3 are formed on both sides of the bottom plate 1 laid between the adjacent tile rods B of the tile roof. . Next, the resin-coated steel sheet C formed in a substantially gate-shape is coated on each of the tile-bar portions B of the existing tile-roof roof, and is firmly fixed to the base E using screws 4. The rising joint 2 formed on one side of the waterproof sheet A is placed and covered, and joined to the coated steel sheet C, and the rising joint 3 formed on the other side of another waterproof sheet A ' It is placed and covered or abuts on the rising joint 2 formed on one side and is joined to the rising joint 2. Similarly, a waterproof sheet A is laid between the tile rod portions B to cover a rising joint 2 formed on one side and a rising joint 3 formed on the other side of another adjacent waterproof sheet A '. Alternatively, they are brought into contact with each other and joined to each other (FIGS. 1 and 2), or another waterproof sheet A ′ adjacent to the rising joint 2 formed on one side of the waterproof sheet A on the upper surface of the resin-coated steel sheet C. The joining process is repeated in such a manner that the rising joints 3 formed on the other side are placed against each other, joined to the coated steel sheet C, and further joined with the joining band sheet D (FIG. 3). Thereafter, the bottom plate 1 of each waterproof sheet A is fixed to the base E by a mechanical fixing method or an adhesive.

When the bottom plate 1 of the waterproof sheet A is fixed to the base E by a mechanical fixing method, the mechanical fixing points (required fixing number) on the bottom plate 1 are the wind resistance required for the waterproof sheet A and the screws 4. There is a method of pre-attaching, post-installing and using a flat bar of a disk-shaped steel plate 5 which is generally used in the bottom plate portion 1 and the like. Effects can be obtained.

The waterproof sheet A used in the present invention is made of a thermoplastic resin or rubber, and has a width slightly larger than the width between adjacent tile rod portions B in the existing tile rod roof. A bottom plate portion 1 laid between the portions B and rising joint portions 2 and 3 are formed on both sides thereof. The rising joint portion 2 formed on one side of the bottom plate portion 1 has a shape consisting of a rising piece 21 and a horizontal piece 22 placed on and covered by the upper surface of each resin-coated steel sheet C (FIG. 1), or the resin-coated steel sheet C (See FIG. 2) consisting of a rising piece 21, a horizontal piece 22, and a hanging piece 23 that covers the entire surface, or a rising piece 21 placed on the upper surface of the resin-coated steel sheet C in abutting manner.
And the horizontal piece 22 (FIG. 3). The rising joint 3 on the other side is composed of a rising piece 31 and a horizontal piece 32 which are placed on and cover the upper surface of the horizontal piece 22 of the rising joint 2. Shape (FIG. 1), or a shape consisting of rising pieces 31 abutting on the hanging pieces 23 of the rising joint 2 (FIG. 2), or rising pieces 31 placed in abutting manner on the upper surface of the resin-coated steel sheet C. And horizontal piece 32
(FIG. 3). By providing a dimensional stability imparting layer on the waterproof sheet A, durability is improved.
Stability can be maintained.

The resin-coated steel sheet C formed in a substantially gate shape used in the present invention is formed in accordance with the size of the tile bar to be repaired.
The steel plate may be coated with a resin and then formed into a substantially gate shape, or the steel plate may be formed into a substantially gate shape and then coated with the resin. The resin to be coated on the steel sheet is not particularly limited. However, when bonding with the waterproof sheet A to be used is performed by solvent welding or hot air fusion, the thermoplastic resin shown below is used in the same manner as the waterproof sheet A in consideration of the bonding property. And rubber are preferable, and a thermoplastic resin and rubber having the same composition as the waterproof sheet A to be used are particularly preferable. The resin-coated steel sheet C is coated on the existing tile rod portions B and fixed to the base E using screws 4 or the like.
The rising joints 2 and 3 provided on both sides of are joined together.

The joining of the resin-coated steel sheet C and the rising joints 2 and 3 of the waterproof sheet A, the joining of the rising joints 2 and 3 of the waterproof sheet A, and the joining of the waterproof sheets A and 2 The method of bonding the bonding sheet D to the bonding belt sheet D includes methods such as heat welding, solvent welding, and an adhesive, and any method may be used. However, from the viewpoint of workability, heat welding and solvent welding are preferred.

The thermoplastic resin and rubber type of the waterproof sheet A are appropriately selected according to the intended product. Examples of the thermoplastic resin include vinyl chloride resins and copolymers of ethylene and vinyl acetate. , Copolymer of ethylene and acrylic monomer, olefin resin, acrylic resin,
Thermoplastic elastomers (olefin-based, polyester-based, urethane-based, etc.) and the like can be mentioned. On the other hand, rubbers include synthetic rubbers and natural rubbers, such as SBR, NBR, chlorsulfonated polyethylene, EPR, EPDM, chloroprene, neoprene, butadiene, and natural rubber. These thermoplastic resins and rubbers may be used alone or in combination of two or more.

The dimensional stability-imparting layer laminated on the waterproof sheet A includes woven fabric, non-woven fabric, metal foil, film, sheet and the like. As woven fabric and non-woven fabric, natural fibers such as hemp, cotton and pulp, and synthetic fibers (polyester) , Polyolefin, polyamide, polyvinyl alcohol, etc.), carbon fiber and glass fiber alone or blended, and a film,
Examples of the sheet include synthetic resins having good dimensional stability, for example, films and sheets of polyester, polyamide, and the like.As the material of the metal foil, aluminum, titanium, copper,
Steel and the like. These woven fabrics, nonwoven fabrics, metal foils, films and sheets may be used alone or in combination of two or more. A woven or non-woven fabric is preferred as the dimensional stability imparting layer in consideration of handleability and workability.

The dimensional stability-imparting layer may be provided at any of the front, middle and back surfaces of the waterproof sheet A, but is preferably located at the intermediate position, whereby the waterproof sheet made of thermoplastic resin or rubber is heat-sealed. In addition, bonding by solvent welding becomes easy, and higher watertightness can be secured. The dimensional stability imparting layer is not limited to one layer, and may be two or more layers. The layer having a thickness of usually about 1 μm to 1.0 mm is used. 0.5mm to 5.0m as the total thickness of the waterproof sheet
m, generally 1.0 mm to 2 mm.

The dimensional stability of the waterproof sheet A is an important property for maintaining the shape of the roofing bar for a long period of time, in particular, for the tension phenomenon at the corner from the bottom plate portion 1 to the roofing bar portion B or the generation of wrinkles in the bottom plate portion 1. As an alternative physical property, the expansion / contraction rate at 80 ° C. for 168 hours is a standard. The elongation is preferably 1.0% or less, more preferably 0.5% or less. 0.2% shrinkage
Or less, more preferably 0.15% or less. That is, when the elongation percentage of the waterproof sheet A exceeds 1.0%, wrinkles occur due to the fixed portion when the mechanical fixing method is used,
This is an aesthetic disadvantage. On the other hand, if the shrinkage rate exceeds 0.2%, it causes a phenomenon of tension at the corner from the bottom plate portion 1 to the tile rod portion B and an increase in separation of the tile rod fixing portion from the resin-coated steel sheet C, resulting in a decrease in wind pressure resistance. This will lead to sheet breakage. The effect on the dimensional stability of the waterproof sheet is different depending on the configuration of the dimensional stability imparting layer.For example, in the case of a woven fabric, the number of threads per unit area and the thickness of the thread, in the case of a nonwoven fabric, the basis weight, metal foil, sheet, film In this case, the effect of the material and thickness is great. Therefore, it is generally difficult to limit each numerical value, and it is necessary to make a comprehensive judgment.

In the case where the dimensional stability imparting layer is provided, the fold can be easily bent by pressing or heating with a roller or the like, and can be designed in accordance with the dimensions of the bottom plate 1 and the tile rod B. In addition, there is no need to use a mold such as extrusion molding that matches the shape of the tile bar.

In some cases, the head of the screw is protruding from the bottom plate of the existing roof tile roof.
It is preferable to lay a foam having a thickness of about 5 mm on the bottom plate portion of the roof of the tile bar or to attach the foam to a portion corresponding to the bottom plate portion on the back surface of the waterproof sheet beforehand.

The joining band sheet D is joined on the rising joint 2 and the rising joint 3 which are joined by butting on the upper surface of the resin-coated steel sheet C, and preferably has a composition similar to that of the waterproof sheet A used. It is preferable to have the same performance as that of the waterproof sheet A, such as weather resistance, shrinkage, and mechanical strength.

By making the bottom plate 1 and the rising joint 2 or 3 of the waterproof sheet A and the band sheet D for joining different colors, a two- or three-color tiled roof is obtained, and the design is further improved. You can also. In order to make the bottom plate 1 and the rising joint 2 or 3 of the waterproof sheet A different colors, a film or sheet of a different color is laminated on either the bottom plate or the rising joint, or a different color. What is necessary is just to coat the paint.

The base E may be a metal plate, a resin plate, a slate plate, concrete or the like. The base of the base E is a state before the renovation of an existing tile bar roof. It can also be applied to a roof structure of a design shape having a tile shape, and in the case of a folded plate roof other than a tile bar, it can be repaired in the same way as a tile bar roof using resin-coated steel sheet adapted to the roof structure. According to these methods, renovation in which the workability is simplified can be performed without damaging the design of the tile bar. In addition, since the joining state can be directly confirmed, reliable waterproof performance can be obtained.
