Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for attaching a hanger for repair that can be easily and firmly attached to the tile rod portion of an existing tile rod roof.

[Conventional technology and issues]

Traditionally, tile stick roofs have been made using groove plates (roof plates), hangers,
Even today, the roofs are still widely constructed using capping materials. When this tile-stick roof becomes obsolete or corrodes after long-term use, and rainwater begins to enter the room, it becomes necessary to replace it with a new roof, and the tile-stick roof becomes obsolete or corroded due to long-term use. It was removed and replaced with a new roof. Since this removal is troublesome and takes many days, recently a new roof has been built directly on top of the tile-stick roof.

When re-roofing the new roof, the hangers are fixed to the existing tile and stick roof main building from above using bolts, nuts, drill screws, etc. as a means of fixation. 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. It was a lot. 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. As a result, the adhesion strength of the hanger is reduced, and the newly installed roof, etc. attached to the hanger has the disadvantage of being easily blown off.

[Means to solve the problem]

Therefore, the inventor worked diligently to eliminate the above drawbacks.
As a result of repeated research, the present invention was developed by fitting a repair hanger with claws directed downward from both sides of the main body into appropriate positions on the tile bar part of an existing tile bar roof, and then attaching the claws to the tile bar part. By biting and fixing the hanger on both sides with a hanger installation tool, the hanger for repair can be easily and firmly fixed, and a new roof can be constructed by attaching a new roof board, etc. to the hanger for repair. The roof can be strengthened as a whole, solving the above problem and achieving the purpose.

〔Effect of the invention〕

In the construction method of the present invention, a repair hanger A having claws 2, 2 directed downward from both sides of the main body part ₁ is fitted into the appropriate position of the tile stick part B1 of the existing tile stick roof B, and then the By biting and fixing the hangers 2 and 2 into both sides of the tile rod part B ₁ with the hanger installation tool C, the repair hanger A is firmly placed in the proper position of the tile rod part B ₁ of the existing tile rod roof B. It can be fixed, and furthermore, the repair hanger A can be easily and reliably fixed to the tile bar part _B1 .

To explain these effects in detail, in the present invention, after the repair hanger A is placed on the tile bar part B ₁ , the claws 2, 2 of the repair hanger A bite into both sides of the tile bar part B ₁ . If it is fixed, the claws 2, 2 will bite into both sides of the tile bar part B ₁ during the fixing work, and at the same time, the side plates of the tile bar part B ₁ will actually be cut up as burrs, and this The strength of the location can be significantly increased, thereby further increasing the mounting strength of the repair hanger A.
A particularly great feature is that it is firmly fixed without using any fixing tools. In turn, the strength of the roof will increase, making it possible to construct a new, stronger roof.

In addition, in conventional roof replacement, a hanger is fixed from above to the main building of the existing tile-and-stick roof using bolts, nuts, drill screws, etc., and if you try to do this on site, the main building will be attached from above the roof. Since it cannot be seen visually, its position is measured in advance using a scale, etc., but even with this, it is often not always possible to securely attach it to the main building position from above, and in reality, it is difficult to securely attach it to the main building from above. However, in the present invention, instead of fixing the hanger to the main building where it cannot be seen, the repair hanger A is attached to the tile bar part _B1 . It has the great advantage that it can be fixed anywhere in the throat, and construction is extremely simple, quick, and reliable.

Further, by using the locking pieces 3, 3 or the movable tongue piece 4 of the present invention, roofing material or wall material can be easily and firmly attached.
