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 mating roof is installed.

[Prior Art and Problems] Traditionally, roofs with tile sticks have been widely constructed using groove plates (roofing materials), 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, the room may get wet, so tents are used to protect equipment, products, etc. , 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-and-stick roof, and not only does the function of the company, residence, etc. stop, but it 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 roof with tile sticks, 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 fitting roof etc. to be attached to the hanger were easily scattered.

[Means to solve the problem]

Therefore, in order to solve the above problem, the inventor has made extensive research and has developed the invention by providing claws that point downward from both sides of the main body at appropriate locations on the tile sticks of an existing tile stick roof. Fit a repair hanger with locking pieces facing upwards from both sides of the tile bar, and fix the hook by biting into both sides of the tile bar, and fix it on both sides of the main plate.
One side of the fitting construction board provided with the engagement side surface portions each having an engagement stepped portion is fitted while the engagement side surface portion is fitted into the locking piece of the repair hanger, and then the adjacent By fitting the engaging side surface on the other side of the mating construction board to the engaging side surface on one side of the front mating construction board and engaging the engaging steps, the existing tiles By leaving the stick roof as it is, there is no need to remove it, and a new mating roof can be easily and quickly installed on top of it.Furthermore, the entire roof can be strengthened. The installation can be done reliably and firmly, and the above-mentioned problem has been solved and the purpose has been achieved.

〔Effect of the invention〕

In the present invention, the tile rod portion of the existing tile rod roof A
A repair hanger B, which has claws 6, 6 directed downward from both sides of the main body 5 and locking pieces 7, 7 directed upward from both sides of the main body 5, is fitted into the appropriate position of _A1 . The claws 6, 6 bite into both sides of the tile bar part _A1 and are fixed, and the engagement step parts 9a, 10a are attached to both sides of the main plate 8.
The engagement side surface portion 9 on one side of the fitting building board C, which is provided with the engagement side surface portions 9 and 10 formed thereon, is fitted while being fitted into the locking piece 7 of the repair hanger B. Then, the engagement side surface portion 10 on the other side of the adjacent fitting construction board C is fitted onto the engagement side surface portion 9 on one side of the front fitting construction board C to form the engagement step portions 10a, 9a. By engaging each other, the existing tile stick roof A
There is no need to remove the roof by leaving it as is, and it is possible to easily and quickly construct a new tile-and-stick roof over it, which in turn shortens the construction period and significantly reduces construction costs. Second, the repair hanger B can be installed easily, quickly and firmly, and thirdly, the existing tile stick roof A and the new mating roof can be double-roofed to make it stronger. be effective.

To explain these effects in detail, in particular, in the present invention, the claws 6, 6 extending downward from both sides of the main body 5
By fitting the repair hanger B provided with and fixing the claws 6, 6 into both sides of the tile rod part _A1 ,
During the biting and fixing work, the claws 6, 6 bite into both sides of the tile bar part _A1 , and at the same time, the side plates of the tile bar part _A1 are actually cut and raised as burrs, and the strength of this part is reduced. This increases the installation strength of the repair hanger B, which in turn increases the strength of the roof, making it possible to construct a new, stronger mating roof. As a means of fixing the hanger to the existing tile-stick roofed main house from above using bolts, nuts, drill screws, etc., if you try to do this on site, the main house cannot be seen from above the roof, so it must be fixed in advance. Although the position is measured using a scale, etc., it is often not always possible to securely attach the hanger to the main building position from above, and in reality, the hanger cannot be visually observed on the existing tile-stick roof. It has been extremely difficult in construction to securely fix the hanger to the main building, but in the present invention, instead of fixing it to the main building, the repair hanger B can be placed at any position on the tile bar part _A1 , making it easier to install. It has a great effect because it can be done extremely simply and quickly.

In addition, since a new fitting roof is to be installed on top of the existing tile stick roof A, the height of the engaging side parts 9 and 10 of the fitting building board C will inevitably become higher, and the new fitting roof will need to be installed. The presence of voids inside the mating parts of the mating roof prevents capillary action of rainwater and improves watertightness (rain closure), which prevents ice banks from forming on the roof after construction and preventing water from stagnant. Even if rainwater does occur, it is extremely difficult for rainwater to enter the interior, and leakage can be reliably prevented.
Furthermore, when constructing the new fitting roof, the tile rod portions _A1 of the existing tile rod roof A can be used as a guide for allocation, making the construction even easier. Furthermore, the existing tile stick roof A and the new mating roof are double-roofed, making the whole roof strong against external forces (tensile loads such as snow loads and wind pressure). It goes without saying that it can also be used as a repair wall for an existing tiled roof wall that is sloped appropriately.

In addition, since the fitting building board C is not fixed to the repair hanger B and is only fitted, even if the fitting building board C thermally expands and contracts in its longitudinal direction depending on the outside temperature, the relative The mating architectural board C is not subject to any thermal stress, thereby reliably preventing the occurrence of thermal distortion, etc., and the occurrence of the plate rattling phenomenon. can also be prevented.

In addition, since the repaired roof of the tile stick roof of the present invention can be mainly repaired using only the fitting construction board C as a repair member, the construction can be performed easily and quickly, and there is an advantage that construction can be performed at a particularly low cost.
