Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a method for remodeling a metal sheet roof.

Conventional Technology Conventionally, for example, in order to modify a leaky metal sheet roof to make it waterproof and insulating, it is possible to apply the insulation and waterproofing construction method that has traditionally been used for flat roofs of structures, for example. Conceivable. In this conventional method, a heat insulating material is first laid on the surface of the flat roof to be heat-insulated and waterproof, and the peripheral edge of this heat-insulating material is fixed by a peripheral joint piece having a cross-section L topography having a sheet joint surface. A large number of intermediate joint pieces having sheet joint surfaces are fixed from above the insulation material to the internal required parts of the surface, and then the peripheral joint pieces and the intermediate joint pieces are sequentially attached while spreading the waterproof sheet wound into a roll over the surface of the insulation material. The method used was to apply adhesive to the joining surfaces of the sheets, and then layer the rewound waterproof sheet on top of it.

However, in this conventional method, the unwinding of the tarpaulin sheet and the application of adhesive to the joint pieces must be carried out at the same time, which makes the work difficult, and requires a skilled person to do the work. There was a risk that the waterproof sheet would be joined to the joining piece while still wrinkled. On the other hand, since the waterproof sheet is sequentially joined to the joint piece while being rewound, the waterproof sheet may be joined to the joint piece while stress is generated in the waterproof sheet during tensioning. If this occurs, the tarpaulin sheet will not be able to expand and contract freely due to temperature changes, resulting in rapid deterioration of the tarpaulin sheet, and this premature deterioration of the tarpaulin sheet will also cause the insulation material to deteriorate quickly. The drawback was that the insulation and waterproofing effect was significantly impaired.

Purpose of the Invention The purpose of this invention is to completely stop rain leakage and give the roof complete waterproofness by attaching a heat insulating material and a waterproof sheet to the upper surface of a leaky metal sheet roof, for example. At the same time, it is possible to add insulation properties to the roof, and the tarpaulin sheet can be installed with a very simple work, and the tarpaulin sheet does not wrinkle, making it easy to install. We would like to provide a method that can prevent the early deterioration of the tarpaulin sheet without residual internal stress during tensioning, has good workability, is excellent in construction, and can achieve reliable insulation and waterproofing. There it is.

Composition of the Invention In order to achieve the above object, the present invention provides insulation on the surface of a metal sheet roof consisting of roofing boards, straw bars arranged at predetermined intervals, and metal plates covering these.

The gist is a method for remodeling a metal sheet roof, which involves the process of joining pieces together.

Embodiments Embodiments of the present invention will be described in detail below based on the drawings.

In the drawing, the metal sheet roof 23 consists of roofing boards 24 and straw bars 25 arranged at predetermined intervals.
and a metal plate 26 covering these.

To remodel such a metal sheet roof 23, first, a heat insulating material 22 is laid on the roof 23. Thereafter, a peripheral edge joint piece 14 having an L-shaped cross section and a sheet joint surface is attached to the peripheral edge of the roof 23 with screws 27, similar to those conventionally attached to rising walls at the peripheral edge of a flat roof. , while fixing the periphery of the heat insulating material 22, intermediate joining pieces 17 are placed on the upper surface of the insulating material 22 at predetermined intervals and facing the straw bars 25, and penetrating the insulating material 22 and the metal plate 26. The intermediate joint piece 17 and the heat insulating material 22 are attached to the cover rod 25 all at once using a screw 27 having a strength of 27.

Here, the peripheral joint piece 14 and the intermediate joint piece 17
In each case, a film 19 made of polyvinyl chloride, which is the same as the waterproof sheet 11 made of polyvinyl chloride, is attached to a main body 18 made of a steel plate with adhesive, and the upper surface of this film 19 is the sheet joining surface 19.
It is considered as a. Further, the shape of the joint piece is arbitrary, and may be a strip-like shape, or may be rectangular or other shape.

Next, the waterproof sheet 11 is spread over the upper surface of the heat insulating material 22 so as not to wrinkle, and then the peripheral edge of the waterproof sheet 11 is joined to the peripheral joint piece 14 with an adhesive. Here, waterproof sheet 1
As No. 1, thermoplastic synthetic resins are used, among which polyvinyl chloride is the most common. A unit of the waterproof sheet 11 is wound into a roll, and usually has a length of 15 m to 20 m and a width of 1.5 to 2.0 m. By sequentially laying the units of the waterproof sheet 11 on the upper surface of the heat insulating material 22 and gluing adjacent parts of the units, one large waterproof sheet is completed. Further, as the adhesive, for example, a solvent such as tetrahydrofuran (THF), which can weld the waterproof sheet and the film of the joining piece, is used.

Next, the adhesive storage section 28 is provided with an adhesive storage section 28 and a needle 21 attached to the tip of the adhesive storage section 28 in a communicating manner.
An adhesive syringe 20 is prepared so that the adhesive is forced out from the tip of the needle 21 by applying pressure to the adhesive inside, and the portion of the waterproof sheet 11 that overlaps each intermediate joint piece 17 is prepared. Then, the needle 21 of the adhesive injector 20 is penetrated, and the adhesive in the adhesive injector 20 is injected between the waterproof sheet 11 and the intermediate joining piece 17, and the injected adhesive is inserted into the waterproof sheet 11. The waterproof sheet 11 is joined to the intermediate joint piece 17 by pressing from above and spreading it along the sheet joint surface 19a of the intermediate joint piece 17 with this adhesive.
