Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a tile nail cutting tool.
[0002]
[Prior art]
Conventionally, asbestos-cement slate or the like (hereinafter referred to as a roof tile) has been used as a flat roof material, but this roof tile has low toughness and may be damaged.
Usually, the roof tiles are rolled up with some overlap, and the roof tiles are fixed to the baseboard by nailing each other, so to remove the damaged roof tiles, it is necessary to remove the nails. is necessary.
Therefore, as shown in Japanese Utility Model Laid-Open No. 60-4134, a roof repair tool for cutting a fixed nail of a roof tile to be extracted with a tool provided with a sharp hook at the tip of a flat and long rod body is known. It has been.
[0003]
Further, a tile nail cutting tool (roof repair tool) for cutting a roof tile fixing nail extracted by a tool provided with a saw blade on a plate-like plate main body in Japanese Utility Model No. 2-5537 is also known.
[0004]
[Problems to be solved by the invention]
However, in the roof repair tool as shown in Japanese Utility Model Laid-Open No. 60-4134, the fixed nail is hit hard and the nail is pulled out by the impact. Therefore, when the strength of the nail is high, it is necessary to repeat a considerable hit. For this reason, there has been a problem that the base plate is damaged and other normal roof tiles that are overlapped are also damaged.
Further, in the tile nail cutting tool as shown in Japanese Utility Model Publication No. 2-5537, the distance that the saw blade reaches the nail depends on the length of the saw blade itself, so the distance between the plate body and the nail to be cut is If the saw blade did not reach the nail for a long time, a sufficiently long saw blade was required.
[0005]
However, this long saw blade has to increase the thickness of the saw blade in order to ensure the strength of the entire saw blade, which increases the manufacturing cost of the saw blade, There was a problem that the manufacturing cost was high.
Further, in the tile nail cutting tool as shown in Japanese Utility Model Laid-Open No. 2-5537, the gap in which the roof tiles are overlapped along the back surface of the roof tile to be replaced with the entire saw blade protruding from the plate body. When cutting a fixed nail, the saw blade and the normal roof tile come into contact with each other, and the saw blade damages the decorative surface of the normal roof tile, or the normal roof tile. There is a problem that the fixed nail other than the fixed nail to be cut is damaged in contact with the fixed nail.
[0006]
Therefore, in view of the above problems, the present invention prevents damage to normal roof tiles and normal fixed nails, and cuts inexpensive tile nails that can cut nails and the like that fix the extracted roof tiles. A tool is provided.
[0007]
[Means for Solving the Problems]
In the present invention, in order to achieve the above-mentioned object, the following solution is adopted. That is, a saw blade that can be inserted into a gap between a pre-drilled roof tile to be extracted and a normal roof tile that is overlapped therewith, and a fixed nail of the extracted roof tile, and a saw blade An extension plate that extends from the rear end of the extension plate and is inserted into the gap, and a handle that extends to the rear end of the extension plate facing the saw blade, and the length of the extension plate in the longitudinal direction. Is set longer than the overlap length in the roof flow direction composed of the extracted roof tile and the normal roof tile, and the combined length of the saw blade and the extension plate is greater than the length of the roof tile in the roof flow direction. It is also characterized by being set longer .
[0008]
According to the above invention, the fixed nail of the extracted roof tile is cut by inserting the saw blade into the gap between the extracted roof tile and the normal roof tile overlapping thereunder and pushing and pulling the saw blade. Therefore, as shown in Japanese Utility Model Publication No. 60-4134, the fixed nail is not hit when the fixed nail is cut, so that the ground plate is damaged or other normal roof tiles that are overlapped are also damaged. There is no end to it .
When the distance between the saw blade and the nail to be cut is long and the saw blade does not reach the fixed nail, it is not necessary to lengthen the saw blade itself like a conventional tile nail cutting tool. If the length of the saw blade is set so that the saw blade reaches the fixed nail, the saw blade comes into contact with the fixed nail, and the fixed nail can be cut with the saw blade. Therefore, even when the saw blade does not reach the fixed nail to be cut, it is not necessary to lengthen the saw blade, so that the manufacturing cost can be suppressed.
[0009]
When the cutting operation is performed by pushing and pulling the saw blade in the roof flow direction, the extension plate occupies most of the roof tile removal tool that passes through the upper surface of the surface of the normal roof tile.
Therefore, the cutting blade is less likely to come into contact with the decorative surface of the normal roof tile, thereby damaging the normal roof tile or contacting the normal roof tile fixing nail to fix the normal roof tile. It is possible to prevent the nail from being damaged.
Further, if a saw blade mounting bracket is provided at the end of the extension plate so that the saw blade can be detached from the extension plate, the saw blade can be freely detached from the extension plate. Therefore, if the saw blade is worn and the fixed nail cannot be cut, it can be used by replacing only the new saw blade. It is.
[0010]
Further, switching means that can be switched to right-handed or left-handed is provided, and the switching means forms the handle in an oval or circular rod shape, and the extension plate without bending the handle in the thickness direction of the extension plate. If it extends from the edge part of this, a cutting operator can perform a cutting operation easily irrespective of a right-handed person or a left-handed person.
[0011]
