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 roof tile) has been used as a flat roof material, but this slate has low whipability and sometimes breaks.
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 this saw blade damages the decorative surface of the normal roof tile. There was a problem in that the normal roof tile fixing nails other than the fixing nails to be cut were damaged by coming into contact with the tile fixing nails.
[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 overlaps the extracted roof tile, and a fixed nail of the extracted roof tile, and the saw blade An extension plate that extends in the thickness direction so that it can be inserted into the gap and extended along the roof surface from the upper side of the roof surface, and an extension plate that faces the saw blade And a handle extended at the rear end portion.
[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.
In addition, since the extension plate extending from the saw blade is interposed between the handshake and the saw blade, the saw blade can reach the fixed nail regardless of the length of the saw blade.
[0009]
In other words, 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 as in the conventional cutting tool for roof tiles, instead of the saw blade, If the length of the extension plate 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.
Further, since the extension plate has flexibility in the thickness direction, as shown in FIG. 3, the operator pulls the handle toward the chest side of the cutting operator during the cutting operation, so that the weight of the operator is increased in the A direction. You can push the saw blade while putting it.
[0010]
Therefore, as shown in FIG. 4, the saw blade can be pushed more strongly than the arm in the direction of the roof flow only by the arm force. The fixed nail can be easily cut.
Further, in this case, as shown in FIG. 4, the cutting worker does not tilt forward, so that the cutting work is easy to perform and the burden on the cutting worker can be reduced.
Further, since the operator's hand is away from the roof surface, the operator's hand does not have a risk of injury due to contact with the roof surface, and the operator can work safely.
[0011]
Further, the length in the longitudinal direction of the extension plate is set to be longer than the overlap length in the roof flow direction constituted by the extracted roof tile and the normal roof tile, and the combined length of the saw blade and the extension plate If the length of the roof tile is set longer than the length of the roof flow direction, when the cutting operation is performed by pushing and pulling the saw blade in the roof flow direction, the roof tile removal that passes the upper surface of the surface of the normal roof tile is removed. The extension plate will occupy most of the tool, so the cutting blade will not come into contact with the decorative surface of the normal roof tile in the cutting operation, thereby damaging the decorative surface of the normal roof tile, It is possible to prevent the normal roof tile fixing nails from being damaged by coming into contact with the normal roof tile fixing nails other than the fixing nails to be cut.
[0012]
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.
[0013]
