ことができることとなつた。``Conventional technology'' In the waterproof roofing method using metal plates,
Due to its excellent weather resistance, corrosion resistance, and durability, waterproof surface materials made of thin stainless steel sheets (hereinafter referred to as stainless steel waterproof surface materials) are increasingly being adopted, and the applicant is also interested in this type of waterproof surface material. We have been developing construction methods (see Japanese Patent Application Laid-Open No. 56-52254). This invention not only simplifies the construction of waterproof roofing using metal plates, but also allows the use of thin steel plates, making it possible to reduce the weight and cost of the roof.

えている。 However, in conventional construction methods, including this invention, a base material such as wood wool board, insulation material, asphalt roofing, or foam sheet is generally laid on the building frame and the hangers are fixed to the hangers. The ends of the stainless steel waterproof surface material are fixed, and the stainless steel waterproof surface material and the base material are insulated except for the part of the hanger. Therefore, after seam welding of stainless steel waterproof facing material, three-dimensional distortion occurs due to the shrinkage stress of the welded part, and many uneven stripes are formed on the facing material, which causes damage to the base material and frame. Not only does the fit and appearance deteriorate, but when the slope is gentle, water drains poorly and dirt tends to accumulate, and there are many problems such as the sound of rain echoing when it rains.

しようとするものである。"Problems to be Solved by the Present Invention" The present invention solves the drawbacks of the conventional waterproof roofing method using metal plates as described above, and improves the compatibility between the stainless steel waterproof surface material and the base material. We aim to provide a waterproof roofing method using metal plates that greatly reduces the distortion of the surface material after welding, has excellent soundproofing properties, reduces dirt on the waterproof surface even on gentle slopes, and improves water flow. It is something to do.

る。``Means to solve the problem'' An elastic sheet for preventing distortion is pasted on the frame or a base material laid on the frame, and then a primer treatment is applied on it, and raised parts are formed on both ends. This method is characterized in that after the stainless steel waterproof facing materials are polymerized and bonded by rolling pressure, the respective stainless steel waterproof facing materials are joined to each other at their rising parts by seam welding.

ながら張り付けるのである。 The drawings are cross-sectional explanatory diagrams showing the construction procedure of the construction method of the present invention. In these drawings, 1 is the frame of a building, and on its upper surface, a base material 2 consisting of plywood, water strip board, etc. and a heat insulating material overlaid on a roofing board is glued. Lay it using an agent, etc. Then, as shown in FIG. 1, an elastic sheet 3 for preventing distortion is attached to the upper surface of this base material 2. For that,
First, a primer treatment 4 is applied to the upper surface of the base material 2.
The primer used is mainly butyl rubber, which is applied to a thickness of about 0.5 mm and dried.
A butyl rubber elastic sheet 3 is pasted on top of it while applying light pressure.

る。 Reference numeral 7 denotes a stainless steel waterproof surface material, which has an upright portion 7a at its end, is molded into a predetermined size and shape, and is transported to the site. Then, as shown in FIG. 3, the upper surface of the elastic sheet 3 is subjected to the same primer treatment 8 as that applied to the base material 2, and the lower surface of the stainless steel waterproof surface material 7 is also subjected to the same primer treatment. Next, the stainless steel waterproof surface material 7 is placed on the elastic sheet 3, and its raised portion 7a is connected to the hanger 5 by spot welding. In this case, the raised portions 7a, 7a of the adjacent stainless steel waterproof surface materials 7, 7 come into contact with each other. Stainless steel waterproof surface material 7 and hanger 5
Once the connection is complete, attach the stainless steel waterproof surface material 7.
Perform rolling pressure on the top. Thereby, the stainless steel waterproof surface material 7 is completely bonded to the elastic sheet 3. Then, as a final step, the waterproof surface materials 7, 7 are watertightly joined by seam welding 9 at their mutually contacting raised portions 7a, 7a.

ト３との接着は維持されることとなる。"Function" After welding the seam between the stainless steel waterproof facing materials 7 and 7, many uneven distortions will occur in other parts of the stainless steel waterproof facing material 7 due to the shrinkage pressure of the welded part. Since the face material 7 is adhered almost entirely to the elastic sheet 3, and the elastic sheet 3 is also entirely adhered to the base material 2,
The elastic sheet 3 elastically restrains the stainless steel waterproof surface material 7 from expanding, contracting, and rising.
The occurrence of distortion in the stainless steel waterproof surface material 7 is greatly reduced, and the adhesion between the stainless steel waterproof surface material 7 and the elastic sheet 3 is maintained.

果を奏するものである。"Effects of the Invention" As explained above, the construction method of the present invention involves pasting a strain-preventing elastic sheet on a building block or a base material laid on the building block, and applying a primer treatment on top of the elastic sheet.
In addition, after polymerizing and bonding the stainless steel waterproof siding materials that formed the raised parts at both ends, each stainless steel waterproof siding material was joined to each other at the raised parts by seam welding to form a waterproof roof. The stainless steel waterproof lining is not insulated from the base material and has an integrated structure that is bonded almost entirely to the base material, eliminating the floating of the stainless steel waterproof lining and significantly reducing the sound of rain when it rains. Ru. In particular, since the stainless steel waterproof lining material is connected to the base material through an elastic sheet, the striped uneven distortion of the stainless steel waterproof lining material that is likely to occur due to seam welding is due to the elasticity of the elastic sheet. , the bond between the two will not break and will be greatly reduced.
Therefore, the stainless steel waterproof surface material blends well with the base material, looks good, and has good water flow even on gentle slopes. Stainless steel does not collect dirt on the waterproof surface and is less likely to get dirty. This has the effect that waterproof roofing using waterproof surface material can be easily and reliably performed.
