Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention provides a method to improve the structure of the roof by leaving the existing tile and stick roof as it is.
This invention relates to a repair roof for an existing tile and stick roof, on which a new roof is constructed by seam welding.

[Conventional technology and its problems]

Conventionally, roofs with tile sticks have been widely constructed using groove boards (roof boards), hangers, and the like. This tile stick roof becomes obsolete due to long-term use,
Or if it became corroded and rainwater entered the room, it became necessary to replace it with a new roof, and the tile-stick roof was completely removed and replaced with a new roof. During this removal, companies, factories, etc. may collect dust, etc. during removal, remove various parts such as groove plates may fall, and in case of rain, tents may be used to protect equipment and products. , tents, etc. had to be set up, and the work or operations of companies, factories, etc. had to be temporarily suspended, and the losses and damages inflicted on companies and factories were enormous. In addition, in gymnasiums, if the floor gets wet with rain, many slip accidents occur during competitions, or the floor warps, making it impossible to hold official competitions, so it is essential to install tents, etc. It was hot.
In addition, in general houses, if roof replacement work is carried out while residents are still living, there is a possibility that it will get rained on, and the removed areas must be replaced with a new roof within the same day, making it difficult to maintain consistency in the work. The disadvantage was that it was troublesome and had poor work efficiency. In either case, it takes time and effort to remove the existing tile-stick roof, which not only halts the functions of businesses and residences, but also increases the number of construction days required to replace the new roof. There were drawbacks such as high costs. In addition, in conventional roof replacement, as a fixing means, a hanger is fixed from above to the main building of the existing tile and stick roof using bolts, nuts, drill screws, etc. When trying to do this on site, the main building cannot be seen from above the roof, so the position is measured in advance using a scale, etc., but even with this, it is often not always possible to securely attach the main building from above. It was. In reality, it was extremely difficult to securely attach the hangers to the main building on the existing tile-stick roof, which was not visible to the naked eye. From such a thing,
There was a drawback that the adhesion force of the hanger was reduced, and the newly installed roof that was attached to it could fly off quickly.

[Means to solve the problem]

Therefore, as a result of intensive research in order to eliminate the above-mentioned drawbacks, the inventor has developed the present invention by attaching a hook extending downward from both sides of the gate-shaped part of the hanger main body to the appropriate position of the tile bar part of the existing tile bar roof. A movable hanger for repair is provided with movable tongue pieces that slide appropriately on the top surface of the gate-shaped part, and the claws bite into both sides of the tile bar part and fix it,
A main plate of a seam weldable architectural board, which has sloped parts on both sides of the main plate, a top part formed outward from the upper ends of both sloped parts, and a rising part from the outer end, is placed on the existing tile-stick roof. The top part was placed on the top surface of the hanger main body while the movable tongue piece of the movable hanger for repair was sandwiched between the opposing rising parts of the adjacent construction board, and these were seam-welded. This eliminates the need for removing the existing tile stick roof, and allows a new roof to be easily and quickly constructed using seam welding, creating an extremely watertight and airtight roof. We can provide
Furthermore, the entire roof can be strengthened, and in particular, the movable hanger for repair can be attached reliably and firmly, thus solving the above-mentioned problems.

is provided. Further, in some cases, the fold 13 may not be provided.

[Effect of the invention] In the present invention, the tile rod portion of the existing tile rod roof A
Claws 5b, 5b directed downward from both sides of the gate-shaped part 5a of the suspender body 5 are provided at appropriate locations in _A1 , and the gate-shaped part 5
A movable hanger B for repair, which has a movable tongue piece 6 that slides appropriately on the top surface of the tile a, is fitted, and the claws 5b are bitten into both sides of the tile rod part _A1 to fix it, and then fixed on both sides of the main plate 7a. Forming inclined portions 7b, 7b, both inclined portions 7
The main plate 7a of the seam-weldable construction board C, which has top parts 7c and 7c formed outward from the upper ends of b and 7b and rising parts 7d and 7d formed from the outer ends, is placed on the existing tile stick roof A. The movable hanger for repair B
By sandwiching the movable tongue pieces 6 and seam welding them, the existing tile stick roof A
There is no need to remove the roof by leaving it as it is, and a new roof can be easily and quickly constructed using seam welding over it, which in turn shortens the construction period and significantly reduces construction costs.
Second, the movable hanger B for renovation can be installed easily, quickly, and firmly; third, the new roof can be made completely watertight (rainproof) and airtight; and fourth, the new roof can be made completely watertight (rainproof) and airtight. can respond well to thermal expansion and contraction, and the fifth
The existing tile stick roof A and the new roof are double-roofed, making it stronger.

To explain this effect in detail, in particular, in the present invention, the claws 5 extending downward from both sides of the gate-shaped portion 5a of the suspender body 5
Move the movable hanger B for repair equipped with b and 5b to the tile bar part A ₁
By fitting the claws 5b, 5b into both sides of the tile bar A1 and fixing them, the claws 5b, 5b bite into both sides of the tile bar part _A1 , and at the same time, they actually cut into the tile bar part The side plate of part A ₁ is cut and raised as a burr, and the strength of this part can be significantly increased, which increases the mounting strength of movable hanger B for repair, which in turn increases the roof strength and makes it stronger. A new roof can be constructed by seam welding, and in addition, in conventional reroofing, hangers are fixed from above to the main building of the existing tile and stick roof using bolts, nuts, drill screws, etc. When trying to do this on site, the main building cannot be seen from above the roof, so the position is measured in advance using a scale, etc., but even with this, it is not always possible to securely fix the main building from above. However, in reality, it was extremely difficult in construction to reliably fix the hangers on the existing tile stick roof to the main building where they could not be seen visually. However, with the present invention,
Instead of being fixed to the main building position, the renovating movable hanger B may be fixed to any position on the tile rod part _A1 , which has the great effect of making the construction extremely simple and quick.

In addition, since a new roof is constructed by seam welding on top of the existing tile stick roof A, the seam welded joints are completely watertight (rainproof), especially when the new roof is installed after construction. Even if an ice embankment forms and standing water occurs, it will not infiltrate the interior at all, and water leakage can be reliably prevented. Furthermore, since it is joined by beam welding, it has excellent airtightness and good soundproofing performance.
Insulation can also be improved by combining it with the existing tile stick roof A.

Furthermore, when constructing a new roof by seam welding, the tile rod portion _A1 of the existing tile rod roof A can be used as a guide for allocation, making the construction even easier. In addition, even if the new seam-welded roof expands and contracts due to the outside temperature, the movable hanger B for repairing the new roof
The movable tongue piece 6 can slide appropriately to absorb the thermal expansion and contraction, and the new roof created by seam welding can be completely free from thermal stress distortion.
In addition, the existing tile stick roof A and the new roof will be double-roofed, making the whole structure strong against external forces (tensile loads such as snow load and wind pressure).
It goes without saying that it can also be used as a reinforcing wall for an existing tiled roof wall that is appropriately inclined.

As mentioned above, there are great advantages in that it is not only easy and quick to construct, but also strong and watertight.
