[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a set screw used to fix a heat insulating board to a building structural material.
[0002]
[Prior art]
In order to fix a heat insulating board in which a hard face material is laminated on a soft heat insulating material to a building structural material such as a pillar or a stud, a two-stage head nail described in Japanese Patent Laid-Open No. 8-49317 or A two-stage screw described in Japanese Patent Application Laid-Open No. 11-14002 is used.
[0003]
As shown in FIG. 4, the two-stage head nail 21 has upper and lower two-stage heads 22 and 23 corresponding to the thickness of the soft heat insulating material. The stepped head nail 21 is configured such that a hard surface material is fixed to a building structure material by the lower step head 23.
[0004]
Further, as shown in FIG. 5, the two-stage screw 24 has a fixed head at an interval corresponding to the thickness of the heat insulating material between a screw head 25 and a screw portion 26 formed with a spiral screw on the tip side. The part 27 is formed, and the two-stage screw 24 screwed into the building structure material from the heat insulating material side is configured so that the hard face material is screwed and fixed to the building structure material by the fixed head 27.
[0005]
[Problems to be solved by the invention]
However, in the conventional two-stage head nail 21 and the two-stage screw 24, the lower head 23 and the fixed head 27 are formed at positions corresponding to the thickness of the heat insulating material. There is a problem that a two-stage head nail and a two-stage screw having different head and fixed head formation positions must be prepared separately.
[0006]
The present invention has been proposed in order to solve the problems of such conventional techniques, and an object of the present invention is to provide a set screw for a heat insulation board that can be handled without problems even if the thickness of the heat insulation material is changed. To do.
[0007]
[Means for Solving the Problems]
In order to achieve this object, the present invention relates to a set screw used to fix a heat insulating board in which a heat insulating material is laminated on a hard face material to a building structure material, wherein a screw head and a helical screw on the tip side are provided. The formed screw portion is integrally formed, and a nut screwing screw portion is integrally formed between the screw head and the screw portion, and a double nut is provided on the nut screwing screw portion. It is characterized by screwing .
[0008]
The present invention also relates to a set screw used to fix a heat insulating board in which a heat insulating material is laminated on a hard face material to a building structure material, and a screw portion in which a screw head and a helical screw on the tip side are formed. Is formed integrally between the screw head and the screw part, and a nut screwing screw part is integrally formed, and a nut is screwed into the nut screwing screw part, and A sleeve corresponding to the thickness of heat insulation is inserted between the screw head and the screw part for screwing.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 shows an embodiment of a set screw of a heat insulation board according to the present invention. In this figure, in this set screw 1, a nut screwing screw portion 4 is formed between a screw head 2 and a screw portion 3 on which a helical screw on the tip side is formed. A double nut 5 is screwed onto the screw.
[0010]
In the set screw 1 configured as described above, the position of the double nut 5 is adjusted by turning the double nut 5 so that the distance h between the screw head 2 and the double nut 5 corresponds to the thickness of the heat insulating material of the heat insulating board. it can.
[0011]
Next, a method of fixing the heat insulation board to the hard face material using the set screw will be described with reference to FIG.
Here, the heat insulating board 6 has a structure in which a soft heat insulating material 7 is bonded and laminated to a hard face material 8. The heat insulating material 7 is made of synthetic resin foam such as polyurethane or polystyrene, and the hard face material 8 is made of synthetic resin plate, plywood, gypsum plate or the like.
[0012]
The heat insulating board 6 has a double nut 5 when the hard face material 8 is brought into close contact with the outdoor side of the pillars 9 and the pillars 10 of the building structure material and the set screw 1 is tightened from the outdoor side of the heat insulating material 7 using an electric tool. The lower surface of this is in contact with the hard face material 8 so that the hard face material 8 is fixed to the building structure material.
[0013]
At this time, since the distance h between the screw head 2 of the set screw 1 and the double nut 5 is adjusted to correspond to the thickness of the heat insulating material 7, in the state where the hard face material 8 is fixed by the double nut 5, the screw The head 2 is flush with the outdoor surface of the heat insulating material 7.
Further, when the set screw 1 is tightened with the electric tool, the nut that forms the lower head is the double nut 5, so there is no concern that the nut portion will loosen.
[0014]
Next, a set screw according to another embodiment will be described with reference to FIG.
In this set screw 1, a nut screwing screw portion 14 is formed between a screw head 12 and a screw portion 13 in which a spiral screw on the tip end side is formed. Are screwed together. In addition, a sleeve 16 having a predetermined length is inserted between the screw head 12 and the nut 15. The sleeve 16 has a length H corresponding to the thickness h of the heat insulating material in cooperation with the nut 15.
[0015]
In the set screw 11 configured as described above, the nut 15 is adjusted by rotating the nut 15 toward the screw head so that the distance h between the screw head 12 and the nut 15 corresponds to the thickness of the heat insulating material of the heat insulating board.
When fixing the heat insulation board to the building structure material using the set screw 1, when the set screw 1 is tightened with an electric tool, the nut 15 screw portion 14 forming the lower stage head is oriented in the screw head direction. Since it is screwed so as to move, the nut does not loosen.
[0016]
【The invention's effect】
As described above, according to the set screw corresponding to claim 1 of the present invention, by changing the position of the double nut screwed between the screw head and the helical screw portion on the tip side, There is an advantage that the distance between the screw head and the double nut can be adjusted according to the thickness of the heat insulating material.
[0017]
According to the set screw corresponding to claim 2, the heat insulating material is obtained by changing the length of the sleeve 16 between the screw head and the helical screw portion on the tip side in accordance with the thickness of the heat insulating material. There is an advantage that the distance between the screw head and the nut can be adjusted according to the thickness of the screw.
