Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nail that is easy to hit and that does not come off easily, and a method of fastening a surface base material such as an outer wall panel of a house or the like to a metal frame using the nail.

[0002]

2. Description of the Related Art Conventionally, when a metal frame B is fastened around a surface base material A such as an outer wall panel as shown in FIG. 9 (a) for reinforcement, a tapping screw C as shown in FIG. 9 (b) is used. Are using. The tapping screw C is made of a hard material penetrating a metal plate, and has a spiral screw carved in the body and a groove into which the tip of a driver enters. Therefore, when the surface base material A and the metal frame B are fastened, a tool such as a screwdriver is used to insert the tapping screw C while pressing and rotating the tapping screw C.

[0003]

However, although the conventional tapping screw C has a sharp tip at the body, it has a problem that it is difficult to enter because the thickness from the base to the tip is the same. . In addition, even after the fastening, the screw thread bites into the member such as the surface base material to make it difficult to pull out, but since there is no burr, there is a problem that it is not sufficient for the action of the force in the pulling direction. is there.
Further, since the groove into which the tip of a driver or the like enters must be formed in the nail head, there is a problem in that the wall thickness of the head must be increased. Further, since the tapping screw C is inserted while being rotated, there is a problem that a long time is required for attachment.

SUMMARY OF THE INVENTION The present invention has been made for the purpose of solving the above-mentioned problems. The means is to provide a burr facing the direction of the nail head on the side surface of the body, and There is a nail which is characterized in that the body portion is formed in a taper shape having a small diameter from the base portion on the nail head side to the tip portion, and the burr is formed in a spiral shape around the body portion. Further, the nailing machine for hammering the nail according to claim 1 is fixed to a fixed portion on an upper portion of the fixed base,
After supporting the metal frame on the supporting portion provided at the lower portion of the fixing base, and further mounting the surface base material on the upper surface of the metal frame,
The nailing machine according to claim 1 is tapped from above the surface base material by the driving machine so that the body of the nail penetrates the surface base material and bites into the metal frame for fastening.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a nail according to the present invention will be described below with reference to the drawings. As shown in FIG. 1, the nail 1 according to the first embodiment has a ring-shaped collar 4 which faces the direction of the nail head 3 around the body 2, and the body 2 has a nail head. The taper shape is such that the diameter gradually decreases from the base portion 5 on the third side toward the tip portion 6 on the opposite side.
The end of the tip portion 6 does not need to be particularly sharp, and the corner portion may be cut as shown in the drawing. The burr 4 may be formed to reach the base portion 5 so as to extend over the entire body portion 2, or may be formed by leaving the base portion 5 as illustrated.

As shown in FIG. 2, the nail 1 according to the second embodiment has a body portion 2 in which a plurality of burrs 4 are formed which face the direction of the nail head 3 and are formed in a protruding shape. It is preferable that the number of the protruding burrs 4 is larger because the locking force is higher, but the number is not particularly limited. Other configurations are the same as those in the first embodiment.

In the nail 1 of the third embodiment, as shown in FIGS. 3 (a) and 3 (b), the nail head 3 is directed to the screw thread spirally formed around the body 2. The burr 4 is formed. Other configurations are the same as those in the first embodiment.

A metal frame B having a U-shaped cross section for reinforcement is fastened and fixed around a surface member A such as an outer wall panel by using the nail 1 according to any one of the first to third embodiments. The case will be described with reference to FIGS. 4 to 8.

As shown in FIG. 4, a fixed base 7 having a C-shaped cross section.
The hydraulic driving machine 9 is fixed to the fixed portion 8 located at the upper part of the above, and the concave portion of the elongated metal frame B having a substantially U-shaped cross section is inserted into the support portion 10 located at the lower part of the fixed base 7. Then, the surface base material A is placed on the upper surface of the metal frame B.

Next, as shown in FIG. 5 (a), the heads 3 of a large number of nails 1 are mounted on the tape 11 at equal intervals, and then, as shown in FIG. 11 reel 1
Prepare the one wrapped around 2. Then, as shown in FIG. 6, a steel pipe 14 and a steel pipe 15 are respectively fixed to two pipe fixing portions 13 of the hydraulic driving machine 9, and the tape is attached above the steel pipe 14 on one supply side. The guide wheel 16 guides the tape 11 with the nails 21 which is supplied by rotating the reel 2 which is separately rotatably supported, into the steel pipe 14, and further, of the hydraulic driving machine 9. Tape feeding section 1 provided at the tip 17
Send to 8. Then, the tape 1 that has come out of the tip portion 17
The tip of No. 1 is passed through the other steel pipe 15 on the discharge side, and attached to the winding wheel 19 provided above the steel pipe 15. By rotating the take-up wheel 19, the tape 11 flows from the reel 12 through the steel pipe 14, the tip portion 17, and the steel pipe 15 to the take-up wheel 19, and the hydraulic type tape in the tip portion 17 is moved. The nails 1 are sequentially supplied to the setting machine 9. The method of supplying the nail 1 is an example, and other means may be used.

Next, the operation in which the nail 1 according to the present embodiment is driven into the surface base material A and the metal frame B will be described. As shown in FIG. 7, the tip portion 17 of the hydraulic type driving machine 9 is moved downward to come into contact with the upper surface of the surface base material A, and then is supplied from the tape 17 as shown in FIG. Ta nail 1
Is hydraulically tapped at the nail tapping section 20 from above the surface base material A. Thereby, the nail 1 penetrates the surface base material A and the metal frame B, and the surface base material A and the metal frame B are firmly fastened. After that, the tip portion 17 is moved upward, and then the surface base material A and the metal frame B are moved to the next fastening position on the support portion 10. The surface base material A and the metal frame B are firmly fixed by waiting for the next supply of the nail 1 to the nail striking section 20 by the rotation of the winding wheel 19 and repeating the same operation. go.

[0012]

As is apparent from the above description, a burr facing the direction of the nail head is attached to the body of the nail, and the body has a taper with a small diameter from the base on the nail head side to the tip. Since it is formed in a shape, when it is used for connecting two or more members, it is difficult for the burr to come off and the strong fastening state can be maintained. Further, since it is formed in a tapered shape, it has an advantage that it can easily penetrate. Furthermore,
Since it is not necessary to form a groove for a driver on the nail head, the nail head can be made thin, and thus there is an advantage that the thickness of the nail head protruding from the member after fastening becomes small and unnoticeable.
Further, since it is not necessary to rotate the nail, the work can be performed smoothly and the work efficiency is improved.

Further, when the burr is formed in a spiral shape around the body portion, the conventional device for manufacturing a screw nail can be used as it is, so that the manufacturing cost becomes low.

When the nail of the present invention is used to fasten the surface base material and the metal frame, the working efficiency is improved, and the projected portion of the nail head from the surface of the finished product is reduced, resulting in an apparent appearance. There is an advantage that a good product can be made.
