Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention can prevent the existing folded plate portion from falling indoors, prevent the acceleration of corrosion, and prevent the occurrence of dew condensation even if the plate is aged and corrosion progresses. Regarding repaired folded plate roofs.

[Conventional technology and its problems, etc.]

Conventionally, when a folded metal roof becomes obsolete or rots after long-term use and rainwater begins to enter the room, it becomes necessary to replace it with a new roof. It 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. Sexuality was occurring.

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 worked diligently to solve the above problems.

As a result of repeated research, the present invention was constructed using an existing folded plate roof with appropriate spacing above the existing folded plate roof via supports and hangers. It consists of a newly installed folded plate roof that has injection holes near the top of the edges of at least every other mountain, and the spacer material covers the top surface of the newly installed folded plate roof that does not have injection holes, and this The foamed resin injected from the injection hole is interposed between the top surface of the existing folded plate roof that corresponds to the gap, and is filled in the metal body within the gap to prevent corrosion due to aging. Even if corrosion progresses, existing folded plates will be prevented from falling indoors and corrosion will be accelerated.

This prevents dew condensation and solves the above-mentioned problems.

Injected foamed resin 14 is injected into the gap 11 between the existing folded plate roof A and the new folded plate roof B through the injection hole 12, filling the entire gap. The adhesive force of the injected foamed resin 14 allows the surface (upper surface) of the existing folded plate roof A and the lower surface of the newly installed folded plate roof B to be bonded together.

Specifically, the injection hose h from the injection device for injection foamed resin 14 is inserted from above the newly installed folded plate roof B into the above-mentioned interval 11 between the spacer materials 13 and 13 on both sides. The amount of foamed resin 14 injected (see FIGS. 7 to 9) is measured visually through the injection hole 12 or by the scale of the device. When it is confirmed that the volume is sold within the interval 11 and the foam is allowed to stand, the spacer material 13 is foamed and the entire interval 11 between the spacer materials 13° 13 is filled to the fullest.

Since the injected foamed resin 14 is viscous and flows down, it is preferable to perform this injection from the eaves side or sequentially from the lower side to the upper side of the roof slope in order to increase the degree of filling. Further, in order to further increase the adhesive strength of the injected foamed resin 14 to the upper surface of the existing folded plate roof A, it is preferable to perform a polishing process on the upper surface.

〔Effect of the invention〕

In the present invention, the existing folded plate roof A is roofed with an appropriate interval 11 above it via supports 9 and hangers 10. The spacer material 13 consists of a newly installed folded plate roof B having injection holes 12 near the top surface 7a of the eight fastening parts of at least every other chevron part 7.

The injected foamed resin 14 injected through the injection hole 12 is interposed between the top surface 7a of the newly installed folded plate roof B, which does not have the injection hole 12, and the corresponding top surface 2a of the existing folded plate roof A. By creating a repaired folded plate roof in which the entire space is filled, firstly, even if the existing folding plate roof becomes obsolete and corrosion progresses, it is possible to prevent the existing folded plate portion from falling indoors; It is possible to prevent corrosion acceleration, thirdly, it has better insulation efficiency and prevents dew condensation, fourthly, it has extremely good filling efficiency, and fifthly, there is no need for removal processing, so factories etc. can be kept in operation. It can be repaired (renovated) as it is, and sixthly, it has the advantage of being able to provide a repaired folded plate roof that is extremely watertight.

To explain these effects in detail, first, since the injected foamed resin 14 has a certain degree of viscosity, it fills the entire space between the existing folded plate roof A and the new folded plate roof B. The existing folded plate roof A is made of the injected foamed resin 14.
It acts to adhesively bond the upper surface and the lower surface of the new folded plate roof B, and this adhesive covers the entire surface of the existing folded plate roof A, and has an adhesive force close to or greater than the own weight of the existing folded plate roof A. Therefore, the existing folded plate roof A
This is the same as strongly adhering to the underside of the newly installed folded plate roof B, and even if the existing folded plate roof A ages and corrodes, it is effective in preventing the existing folded plate part from falling indoors. be.

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 becomes old and corroded, if the injected foamed resin 14 is placed and adhered to its 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.

Also, the distance l between the existing folded plate roof A and the new folded plate roof B
When the entire structure is filled with the entire injected foamed resin 14, there is hardly any air flowing between the upper and lower two layers of the roof, which has the advantage of eliminating internal condensation. This has the effect of significantly increasing heat insulation performance.

In particular, in the present invention, at least one of the newly installed folded plate roofs B
It has an injection hole 12 near the top surface 7a of the mountain-shaped part 7,
Since the spacer material 13 is interposed between the top surface 7a of the newly installed folded plate roof B where there is no injection hole 12 and the corresponding top surface 2a of the existing folded plate roof mA, the injected foamed resin 14 Since the injected foamed resin 14 is filled within the interval ll and also within the opposing spacer materials 13 and 13, the injected foamed resin 14 can be reliably filled in the longitudinal direction of the folded plate roof with a constant width. Since the roof can also be filled evenly, it is possible to fill the roof easily, quickly, and with extremely high efficiency.

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. For this reason, in the present invention, in particular, the spacer material 13.13 is limited to a certain width and is injected only in the longitudinal direction of the folded plate roof with good fluidity. This has the effect of ensuring airtight packing between layers.

Further, an injection hole 12 is provided near the top surface 7a, and the injection hole 1
By injecting from 2, when the injected foamed resin 14 is foamed within the interval ll, the amount that overflows from the injection hole 12 is small, and the injected foamed resin 14 is not wasted, especially when newly installed folding plates. There is an advantage that even the upper side of the chevron portion 7 of the roof B can be filled evenly.

As described above, in the present invention, in order to repair (renovate) the existing folded plate roof A while leaving it as it is, it is possible to repair (renovate) a building (factory).

Of course, it also has the advantage of being able to be constructed without impairing the functionality of the Company 1 gymnasium, etc.).

In addition, the newly installed folded plate roof B is a boltless folded plate roof with a fastened type, and has a completely different image from the existing folded plate roof A. Moreover, because it is boltless, rainwater can leak out from the bolt holes as it ages. The problem of infiltration can be reliably resolved,
- It has the effect of creating a repaired folded plate roof with high water tightness.

Note that the cap material 15 is inserted into the injection holes 12, 12. ... not only ensures watertightness of the repaired folded plate roof, but also makes the repaired folded plate roof watertight by covering and fitting the chevron 7 where the injection holes 12.12. . . . has the advantage of being coated and having a favorable appearance.
