Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a waterproof roofing method using stainless steel plates on metal plates.

``Conventional technology'' In waterproof roofing methods that use metal plates, thin stainless steel plates are increasingly being used due to their excellent weather resistance, corrosion resistance, and durability, and even one piece is being sold to customers. , has been developing this type of waterproofing method (Japanese Unexamined Patent Publication No. 1983
(Refer to Publication No.-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.

However, in conventional construction methods, including this invention, a base material such as wood wool board, heat insulation material, asphalt roofing, or foam sheet is generally laid on top of 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.

"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 allows for good compatibility between the metal waterproof surface material and the base material. To provide a waterproof roofing method using metal plates that greatly reduces 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.

``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 if necessary, primer treatment is applied to this, and both ends are This method is characterized in that, after polymerizing the metal waterproof surface materials forming the raised portions and adhering them by rolling pressure, the respective metal waterproof surface materials are joined to each other at the raised portions by seam welding.

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

The drawings are cross-sectional explanatory diagrams showing the construction procedure of the construction method of the present invention. In these figures, 1 is the building frame, with plywood and plywood on the top surface.
A base material 2 consisting of a heat insulating material overlaid on a flooring board such as a piece of wood is laid using an adhesive or the like.

Then, as shown in FIG. 1, an elastic sheet 3 for preventing distortion is attached to the upper surface of this base material 2. To do this, first, a primer treatment 4 is applied to the upper surface of the base material 2. The primer used is mainly butyl rubber, and this is 0.5ff.
The material is coated to a certain thickness, dried, and a butyl rubber elastic sheet 3 is pasted thereon while being rolled.

Next, as shown in FIG. 2, a hanger 5 for fixing the waterproof surface material to the frame 1 is placed on a predetermined position marked on the attached elastic sheet 3, and an anchor is attached to the frame 1. 6 and install it. Note that the hanger 5 may be attached to the base material z prior to pasting the elastic sheet 3.

On the other hand, the stainless steel waterproof surface material 7 has an upright portion 7a at the end thereof, 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 a primer treatment 8 similar to that applied to the base material 2, and
The same primer treatment is applied to the lower surface of the stainless steel waterproof surface material 7. Next, the stainless steel waterproof surface material 7 is placed on the elastic sheet 3, and its raised portion 7a is joined to the hanger 5 by spot welding. In this case, the raised parts a and 7a of the adjacent waterproof surface materials 7 and 7 come into contact with each other. After the waterproof surface material 7 and the hanger 5 have been connected, rolling pressure is applied to the waterproof surface material 7. Thereby, the waterproof surface material 7 is completely adhered to the elastic sheet 3. and.

As a final step, each of the waterproof face members 7.7 is watertightly joined by seam welding 9 at the standing portions 7a, 7a in contact with each other.

``Effect-1 After seam welding of the waterproof facing material 7.7, many uneven distortions will occur in other parts of the waterproof facing material 7 due to the shrinkage stress of the welded part, but the waterproof facing 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, so that the elastic sheet 3 elastically restrains the expansion, contraction, and lifting of the waterproof surface material 7. As a result, the occurrence of distortion in the waterproof surface material 7 is greatly reduced, and the adhesion between the waterproof surface material 7 and the elastic sheet 3 is maintained.

"Effects of the Invention" As explained above, the construction method of the present invention involves pasting an elastic sheet for preventing distortion on a building block or a base material laid on the building block, applying a primer treatment on top of the elastic sheet, and After the metal waterproof surfacing materials forming the raised parts at both ends were polymerized and adhered, each metal waterproof surfacing material was joined to each other at the raised parts by seam welding to perform waterproof M-roofing. The metal waterproof lining material is not insulated from the base material and is bonded to almost the entire surface to form an integrated structure, so the metal and 4 waterproof lining materials do not float up, and the sound of rain during rain is significantly reduced. be done. In particular, since the metal waterproof surfacing material is combined with the base material through an elastic sheet, the striped uneven pattern of the gold-tin waterproof surfacing material that tends to occur due to seam welding is caused by the elasticity of the elastic sheet. This means that the bond between the two will not break and the weight will be reduced to a large extent. However, the metal waterproof surface material and the base material fit well, and it is easy to install, and water flows well even on gentle slopes, and there is no accumulation of dirt on the waterproof surface, resulting in less dirt. This has the effect that waterproof roofing with metal plates can be done easily and easily.
