2. Description of the Related Art In a wooden building by a conventional framing method, a board is fixed to a pillar or a beam by nailing it to a wall or a ceiling.

[0003]

In recent years, a large amount of waste material generated when an old house is dismantled has caused a problem of waste disposal. In a wooden building using the conventional frame construction method, a nail that has been hammered out is pulled out without a nail at the time of disassembly, so that the nail is bent and the nail cannot be reused. In this case, if it is fixed with a screw nail, the screw nail can be rotated and removed, and the screw nail can be reused, but in the case of a screw nail, it can not be fixed by hitting when fixing , There is a problem that it is difficult to use. In addition, when a plate made of an aluminum plate and a wood fiber board is stuck with a nail, and then the nail is pulled out and dismantled, the wood fiber board is damaged, and there are many board materials that cannot be reused. There was a problem.

[0004] The present invention has been made in view of such conventional problems, and a shaft-shaped fixing member and a plate fixing structure capable of reusing building materials and reducing the problem of waste disposal. And to provide a building construction and demolition method.

[0005]

In order to achieve the above object, a shaft-like fixing member according to the present invention has a thread on a shaft,
The head has a shape for screw rotation, and the thread is inclined such that the width of the tip side slope is longer than the width of the head side slope, and the tip side slope is narrowed from the head side to the tip side. The ridge line of the screw thread and the valley line of the groove are linear, and when the head is rotated, the groove is formed of a soft resin that remains adhered to a fixed portion and can be separated from the groove. It is characterized by being filled up to the height of the ridgeline.

[0006] The shaft-shaped fixing member according to the present invention may be any fixing member having a pin for a building material, a screw nail, a bolt, a screw, or a screw having a thread on a shaft and a screw rotating shape on a head. Good. The shape for screw rotation may be a minus groove, a cross groove, or another concave portion, or may be a square, hexagon, or other polygonal outer shape.

In the shaft-shaped fixing member according to the present invention, the head is hit in the direction of the tip to hit the fixed portion. If the tip of the shaft-shaped fixing member is not pointed like a nail, a hole for fixing the shaft-shaped fixing member is formed in the fixing portion in advance. The shaft-shaped fixing member has a width of the tip side inclined surface longer than a width of the head side inclined surface, and the tip side inclined surface of the screw thread is inclined so as to be narrowed from the head side to the tip side. , Smoothly proceeding to the tip side, and hard to come off on the head side. Further, since the ridge line of the thread and the valley line of the groove of the shaft-shaped fixing member are linear, the width of the tip side inclined surface of the thread can be increased without changing the thickness of the shaft. Facilitates progression to the side. When removing, the head having the screw rotating shape can be rotated and removed with an electric screwdriver or manually. The removed shaft-shaped fixing member can be reused.

[0008]

Particularly, in the shaft-shaped fixing member, since the soft resin fills the groove, the screw thread smoothly advances to the tip end side without being caught in the fixing portion when hitting. The soft resin improves the airtightness of the fixed portion between the shaft-shaped fixing member and the fixed portion while the shaft-shaped fixing member is struck to the fixed portion. When the head having the screw-rotating shape is rotated by an electric screwdriver or manually to remove the soft resin, the soft resin remains adhered to the fixing portion and only the shaft-shaped fixing member can be removed. The removed shaft-shaped fixing member can be reused.
The soft resin is, for example, a urethane resin.

[0010] A plate material fixing structure according to the present invention has a plate material obtained by laminating an aluminum plate and a wood fiber plate,
It is characterized in that the periphery is fixed to a fixed place by the above-mentioned shaft-shaped fixing member.

In the plate material fixing structure according to the present invention, the plate member formed by bonding an aluminum plate and a wood fiber plate can be removed by rotating the head of the shaft-shaped fixing member by an electric screwdriver or manually. Easy to dismantle,
Since a load is not applied when removing the shaft-shaped fixing member, it can be reused without damaging the wood fiber board. The plate material may be used as a wall plate, and the plate material may be any of a wall material, a ceiling material, and a floor material.

In the construction and dismantling method according to the present invention, a building has a thread on a shaft and a shape for screw rotation on a head, and the thread has a head-side inclined surface having a width of a head. It is longer than the width of the part-side inclined surface, the tip-side inclined surface is inclined so as to narrow from the head side to the tip side, the ridge line of the screw thread and the valley line of the groove are linear, and the head is rotated. The groove is filled to the height of the ridge line of the screw thread with a soft resin that remains adhered to the fixed portion when peeled off from the groove, and is formed of an aluminum plate and wood fiber by a screw nail having a sharp tip. It is characterized in that a plate material formed by laminating a plate is fixed to a fixed portion by hitting it, and at the time of disassembly, the screw nail is rotated and removed from the plate material.

In the construction and dismantling method according to the present invention, at the time of building construction, the plate can be easily fixed by hitting a screw nail to the plate, as in the case of using a general nail. . At the time of disassembly, the screw can be easily removed by rotating the screw nail with an electric screwdriver or manually.
