本考案は、断熱材に用いられる発泡スチロール
樹脂用釘に関する。[Detailed Description of the Invention] The present invention relates to a styrofoam resin nail used for heat insulation.
従来、発泡スチロール樹脂よりなる断熱材用の

るようなおそれがある。 Conventionally, there are nails for insulation made of polystyrene foam that have small protrusions formed on the circumference of the shaft of the nail to prevent them from coming off, such as in Utility Model Application Publication No. 89807/1983, but polystyrene foam has good elasticity. Because of this, there is a risk that the small protrusions on the peripheral surface will gouge the foamed polystyrene resin when the shaft is driven, resulting in slack in the driven portion of the shaft.

たものである。 The present invention was developed in view of the above-mentioned problems, and is a flat plate-shaped body with a rectangular cross section, which has a sharp point at its tip, and a flat plate that crosses the axial direction of the shaft obliquely on the base end surface of the shaft. By inserting the shaft into the styrofoam resin at an angle, the shaft prevents the shaft from escaping, and the shaft is made of a plate-shaped body with a square cross section to prevent rotation. The head does not protrude from the surface of the styrofoam resin even though it is inserted into the styrofoam resin.
次に本考案の実施例の構成を添附図面について
説明する。 Next, the configuration of an embodiment of the present invention will be explained with reference to the accompanying drawings.
１は軸部で、断面四角形の合成樹脂製扁平板状
体であり、先端を尖らせて尖鋭部２が形成され、
基端面には円盤状頭部３が一体に形成され、この
円盤状頭部３の軸方向に対して軸部１の軸方向が
交叉するように軸部１が傾斜して形成されてい
る。 Reference numeral 1 denotes a shaft portion, which is a flat plate made of synthetic resin with a square cross section, and has a sharpened tip to form a sharpened portion 2;
A disc-shaped head 3 is integrally formed on the base end surface, and the shaft 1 is formed to be inclined so that the axial direction of the shaft 1 intersects with the axial direction of the disc-shaped head 3.
次にこの実施例の作用について説明する。 Next, the operation of this embodiment will be explained.
発泡スチロール樹脂よりなる断熱材４，４を重

り断熱材４は抵抗が少ないこと及び軸部１が扁平
板状体であることからそのまま重ね合せた断熱材
４，４に傾斜して打込まれる。したがつて断熱材
４，４の結合を離間する方向の力Ｆが作用した場
合は軸部１の脱出方向の力f1と直角の分力f2が作
用して軸部１の脱出が防止される。 The heat insulating materials 4, 4 made of styrofoam resin are overlapped, and the shaft portion 1 is held in a hand so that the outer surface of the head 3 and the outer surface of the heat insulating material 4 are parallel, and the shaft portion 1 is tilted so that its tip is sharpened. After inserting about 1/3 of the length from part 2 into the insulation material 4, the upper edge of the inclined head 3 is hammered in the direction of the axis of the shaft part 1 with a hammer etc., so that the insulation material 4 has no resistance. Since the shaft portion 1 is small and has a flat plate-like shape, it is directly driven into the overlapping heat insulating materials 4, 4 at an angle. Therefore, when a force F is applied in a direction that separates the bond between the heat insulating materials 4, 4, a component force f2 perpendicular to the force f1 in the direction of escape of the shaft part 1 acts, preventing the shaft part 1 from coming off. be done.

い。 According to the present invention, a flat plate-shaped body with a rectangular cross section is formed with a sharp point at its tip, and a flat head that diagonally intersects the axial direction of the shaft is formed on the base end surface of the shaft. By inserting the shaft part into the insulation material made of foamed polystyrene resin at an angle, the shaft part is difficult to escape from the force in the direction of separation of the stacked insulation materials, and the insulation materials can be reliably bonded.
There is no need to form small protrusions or the like on the circumferential surface of the shaft to prevent the shaft from coming off. Moreover, since the shaft is a flat plate-like body and has a sharp point at the tip, the shaft has small protrusions on the circumference, and when inserted, the shaft is inserted like a knife. The resistance is small, the insulating material made of inelastic and brittle styrene foam resin is not damaged, and the effect of preventing slipping out can be further ensured, and the operation of inserting the shaft part in an inclined state is facilitated. Furthermore, since the shaft portion is a flat plate-like body with a square cross section, it has a good anti-rotation effect. Furthermore, since a flat head that diagonally intersects the axial direction is formed on the base end surface of the shaft, the shaft can be inserted so that the head is parallel to the surface of the styrofoam resin insulation material. Even though the head is inserted in an inclined state, the head does not protrude from the surface of the foamed polystyrene resin insulation material, so it does not get in the way or damage others.
