Regarding repaired folded plate roofs.

(Conventional technology and its problems, etc.) Traditionally, when a metal folded roof becomes obsolete or corrodes after long-term use and rainwater begins to enter the room, it is necessary to replace it with a new roof. The metal folded plate roof was completely removed and replaced with a new roof. In addition, metal folded plate roofs usually do not have sheathing boards like the wooden wool boards used in tile stick roofs, and as a result, there is a risk that the existing folded plates may fall off indoors if they become old and corrode. sex was produced.

Even with aging, the operating efficiency of companies, factories, etc.
To protect equipment, products, etc., do not reroof.
In addition, it is possible to prevent the aging and corroded existing folded plate portion from falling indoors, and also to prevent the corrosion from accelerating. The roof is in desperate need of repair.

[Means for solving problems]

Therefore, the inventor conducted extensive research to solve the above-mentioned problems, and as a result, the present invention was constructed by installing an existing folded-plate roof with an appropriate distance above the existing folded-plate roof via a support. The new folded plate roof has injection holes near the top of at least every other mountain, and the spacer material covers the top surface of the new folded plate roof without injection holes and the corresponding existing folded plate roof. By creating a repaired folded plate roof in which the injected foamed resin is interposed between the top surface and injected through the injection hole and is filled in the entire interval, even if the existing folded plate portion deteriorates and corrosion progresses, it will not be damaged. It can prevent falling indoors, prevent corrosion from accelerating, prevent dew condensation, etc., and solve the above-mentioned problems.

〔Effect of the invention〕

In the present invention, the existing folded plate roof A is roofed with an appropriate distance 9 above the support 8. The spacer material 11 consists of the newly constructed folded plate roof B having injection holes 10 near the top surface 7a of at least every other chevron portion 7, and the spacer material 11 covers the top surface 7a of the newly constructed folded plate roof B which does not have the injection holes 10, and this By providing a repaired folded plate roof in which the injected foamed resin 12 injected from the injection hole 10 is interposed between the top surface 2a of the existing folded plate roof A corresponding to the gap 9 and the injected foamed resin 12 is filled throughout the gap 9. , Firstly, even if the existing folded plate roof A becomes old and corrosion progresses, the existing folded plate part can be prevented from falling indoors, secondly, corrosion can be prevented from accelerating, and thirdly, the insulation efficiency is superior. Condensation can be prevented, fourth, the filling efficiency is extremely good, fifth, there is no need for removal and repairs can be made while the factory is in operation, and sixth, the existing folded plate roof can be repaired. By installing a new folded plate roof B having the same shape as A, it is possible to improve the repair effect while keeping the roof image similar to the conventional one.

To explain these effects in detail, first, since the injected foamed resin 12 has a certain degree of viscosity, when it is filled into the entire space 9 between the existing folded plate roof A and the new folded plate roof B, the The injected foamed resin 12 acts to adhesively bond the upper surface of the existing folded plate roof and the lower surface of the new folded plate roof B,
This adhesive covers the entire surface of the existing folded plate roof A, and has an adhesive force close to or greater than the weight of the existing folded plate roof 11A, and therefore, the existing folded plate roof A has an adhesion force that is greater than or equal to the weight of the existing folded plate roof 11A. This is the same as strongly adhering to the lower surface, and even if the existing folded plate roof A ages and corrosion progresses, it has the effect of preventing the existing folded plate portion from falling indoors.

Furthermore, it is also possible to ensure the safety of the existing folded plate roof A, which has progressed to aging.

Furthermore, even if the existing folded plate roof A ages and corrodes, if the injected foamed resin 12 is placed and adhered to the surface, the surface of the existing folded plate roof A will be in a vacuum state, blocking oxidation. This also has the advantage of preventing corrosion.

Furthermore, when the entire space 9 between the existing folded plate roof A and the new folded plate roof B is filled with injected foamed wood J1112, almost no air will circulate between the two upper and lower layers of the roof.
This has the advantage of eliminating internal condensation.

This has the effect of significantly increasing heat insulation performance.

In particular, in the present invention, the injection hole lO is provided near the top surface 7a of at least every other chevron portion 7 of the newly installed folded plate roof B, and the spacer material 11 is provided at the top of the newly installed folded plate roof B where the injection hole 10 is not present. Since it is interposed between the surface 7a and the corresponding top surface 2a of the existing folded plate roof A, the injected foamed resin 12 is filled within the interval 9 and also within the opposing spacer material 11.
11, the injected foamed resin 12 can be reliably filled in the longitudinal direction of the folded plate roof with a constant width, and as a result, the entire roof can be evenly filled, which is simple, quick, and extremely efficient. It has the effect of filling.

To explain this in more detail, a folded plate roof is formed into a relatively large corrugated shape, and unlike a flat roof, it is impossible to inject evenly from only one side in the width direction of the folded plate roof. This has been experimentally proven. Therefore, in the present invention, in particular, by limiting the spacer material 11.11 to a certain width and injecting it only in the longitudinal direction of the folded plate roof with good fluidity, when looking at the entire construction, the upper and lower two This has the effect of ensuring airtight packing between layers.

Further, an injection hole IO is provided near the top surface 7a, and the injection hole 1
By injecting from 0, when the injected foamed resin 12 is foamed within the interval 9, the amount overflowing from the injection hole 10 is small.
There is an advantage that the injected foamed resin 12 is not wasted, and in particular, even the upper side of the chevron portion 7 of the newly installed folded plate roof B can be filled evenly.

As described above, in the present invention, since the existing folding board shop LLA is repaired (renovated) as it is, it naturally has the advantage that it can be constructed without impairing the function of the building (factory, company gymnasium, etc.).

In addition, the new folded plate roof B will be a superimposed folded plate roof using bolts and nuts 4, etc., but it will have the same shape as the existing folded plate roof A, and will be a new version of the existing folded plate roof flA. This has the effect of making use of the image of the existing folded plate roof A.

In addition, the cap material 13 is inserted into the injection hole t of the newly installed folding board shop 11B.
If it is covered and fitted to the chevron portion 7 where o, to,... exist,
Not only does this ensure that the repaired folded plate roof is watertight, but also the injection holes 10, 10. . . . has the advantage of being coated and having a favorable appearance.
