BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support tape for fasteners, and more specifically to support screw nails, nails, etc. arranged side by side at regular intervals so as to enable continuous driving with a dedicated tool. Regarding tape.

[0002]

2. Description of the Related Art For example, as shown in FIG. 4, a support tape 1 for supporting screw nails at regular intervals is provided with a support portion 3 for a screw nail A in a longitudinal direction of a belt-shaped base body 2 made of synthetic resin. Are provided at regular intervals, and the supporting portion 3 is provided so as to project around the insertion hole 4 on the lower surface of the strip-shaped base 2 and the insertion hole 4 provided so that the shaft portion B of the screw nail A fits on the strip-shaped base 2. It is formed of a cylindrical support cylinder 5, and the boundary portion between the strip base 2 and the support cylinder 5 is made thin so that the head C can easily pass through the belt base 2 when the screw nail A is driven. A plurality of kerfs 6 were provided on the upper part of 5.

Further, in such a support tape 1, when the screw nail A is driven, the support cylinder 5 is split in the longitudinal direction by the passage of the head C, and remains on the belt-shaped substrate 2 even after the head C has passed. Ideally,

[0004]

However, the head C
The thin wall thickness of the boundary portion between the belt-shaped substrate 2 and the support cylinder 5 and the formation of the kerf 6 for smooth passage of the above-mentioned result reduce the strength of the boundary portion. When a large force is applied to the boundary portion, the boundary portion is torn and the supporting cylinder 5 is detached from the belt-shaped base body 2 in a tubular shape.

In this way, when the support cylinder 5 is detached from the strip-shaped base 2 in a tubular shape, as shown in FIG. 5, the support cylinder 5 is attached to the shaft portion B of the screw nail A, and the screw nail A is attached. Will be driven into the joints of building materials, etc., and there is a problem in that reliable fastening cannot be obtained.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a support tape for a fastener in which the tubular support is not detached from the belt-shaped substrate and is not driven while the support is still attached to the shaft of the fastener. To provide.

[0007]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a support tape for a fastener, in which support portions for inserting the fastener are provided at regular intervals in the longitudinal direction of a belt-shaped substrate. The supporting portion is composed of a fixing tool insertion hole provided in the strip-shaped base body and a support tube projecting around the fixing tool insertion hole on the lower surface of the strip-shaped base body, and a corner portion of the lower surface of the belt-shaped base body and the outer surface of the support tube is formed. This is a structure in which a reinforcing portion is provided in part.

In the present invention, the upper portion of the support cylinder may be divided into a plurality of cut grooves, and the reinforcing portion may be provided at a position between the cut grooves.

Further, the number of the reinforcing portions may be smaller than the number between the cut grooves, and the shape of the reinforcing portions may be formed in a granular shape or a plate shape narrower than the width between the cut grooves. .

[0010]

When the fastener is driven while the fastener is supported by the supporting portion of the supporting tape, the head of the fastener passes through the insertion hole of the strip-shaped base body and the support tube so as to spread them. At this time, the support tube may be torn in the vertical direction and may also be torn from the boundary portion with the belt-shaped substrate.

However, even if the support tube is torn from the boundary,
Since a part of the boundary portion between the support cylinder and the strip-shaped base is connected to the strip-shaped base by the reinforcing portion, the holding cylinder does not separate from the strip-shaped base at this connection portion, and therefore the holding cylinder is attached to the shaft portion of the fixture. You can't be hit with a mark.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS.

As shown in the figure, the support tape 11 has a structure in which support portions 13 through which the screw nails A are inserted are provided at regular intervals in the longitudinal direction of a belt-shaped substrate 12 made of synthetic resin.

The support portion 13 has an insertion hole 14 formed in the belt-shaped base 12 so that the shaft portion B of the screw nail A can be fitted thereto, and a support cylinder projecting around the insertion hole 14 on the lower surface of the belt-shaped base 12. 1
5, the support cylinder 15 has the same inner diameter as the insertion hole 14, and the shaft portion B of the screw nail A is held by the support cylinder 15.

In the portion of the strip-shaped substrate 12 where each supporting portion 13 is provided, the periphery of the insertion hole 14 is a thin wall portion 16 which is recessed on the upper surface side. The thin thick portion 16 is formed coaxially with the insertion hole 14 with a diameter that matches the head C of the screw nail A, and is not limited to the circular shape as shown in the drawing.
A shape such as a polygon or an ellipse can be adopted.

Further, from the upper portion of the support cylinder 15 to the thin-walled thick portion 16
Is provided with a plurality of kerfs 17, and by these kerfs 17,
The support cylinder 15 is divided into a plurality.

A reinforcing portion 18 for connecting the belt-shaped base 12 and the support cylinder 15 is provided at a part of a corner of the lower surface of the belt-shaped base 12 with the outer peripheral surface of the support cylinder 15. The reinforcing portion 18 is located between the cut grooves 17 described above, and as shown in FIG. 1, the belt-shaped base body 12, the support cylinder 15 and the reinforcing portion 18 are integrally formed of synthetic resin, and the shape and the number thereof are The positions to be provided may be appropriately selected according to the shapes of the head portion C and the shaft portion B of the screw nail A.

In the illustrated case, the number of the reinforcing portions 18 is smaller than the number between the cut grooves 17, and the shape thereof does not cover the entire space between the cut grooves 17, but is narrower than the width between the cut grooves 17. It is formed in a granular or plate shape.

In the illustrated case, a screw nail A is used as a fastener.
However, it may be a nail, a screw, or the like.

The support tape of the present invention has the above-described structure. When the screw nail A is inserted into each support portion 13 of the support tape 11 from above so that the head portion C of the support tape 11 abuts on the belt-shaped base body 12, FIG. As described above, the shaft portion B is supported by the support cylinder 15, and the screw nails A are arranged in the longitudinal direction of the strip-shaped base 12 at regular intervals.

When the screw nail A supported by the supporting tape 11 is continuously driven by a driver of a dedicated tool, the head C
Will pass through the insertion hole 14 of the strip-shaped base 12 and the support cylinder 15 by spreading them.

At this time, the insertion hole 14 is rich in expandability due to the thin wall thickness portion 16 and the cut groove 17, and does not give a great resistance to the passage of the head portion C.

Further, the cylindrical support cylinder 15 is opened by the passage of the head C, and is torn vertically from any of the cut grooves 17 to allow the passage of the head C.

FIG. 3 shows a state in which the support cylinder 15 is torn in a plurality along the vertical direction, and at this time, the support cylinder 15 may also be torn from the boundary portion with the belt-shaped substrate 12. However, the support cylinder 15 and the strip-shaped base 12 are connected to each other by the reinforcing portion 18 between the cut grooves 17, and since this connecting portion is strong in strength, the boundary portion between the support cylinder 15 and the strip-shaped base 12 is torn. Even in such a case, the support cylinder 15 is connected to the strip-shaped base 12 at the reinforcing portion 18, and the support cylinder 15 does not separate from the strip-shaped base 12 even after the head C has passed, and therefore, The support cylinder 15 is attached to the shaft portion B of the screw nail A.
It is possible to surely prevent the screw from being screwed on.

[0025]

As described above, according to the present invention, since the reinforcing portion is provided on the lower surface of the belt-shaped base body and a part of the corner portion of the outer peripheral surface of the support cylinder, the head is penetrated when the fastener is driven. Even if the support cylinder is torn from the boundary portion with the belt-shaped base, the reinforcing portion keeps the support cylinder connected to the belt-shaped base and the support cylinder is separated from the belt-shaped base. No, therefore, the fastener is not driven in or screwed in with the support cylinder attached to the shaft,
As a result, reliable fastening by the fastener can be obtained.
