Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a connection structure of diagonal connection nails that are connected diagonally in parallel to a long connection member.

(Prior Art) A power-operated nail gun that drives nails continuously uses a connecting nail in which nails are connected by a long connecting member. However, when the connecting member is fixed to the nail, a portion of the connecting member is driven out together with the nail, and there is a risk that the connecting member will fly off when being driven into the material to be driven. To prevent this, a structure was developed in which the upper and lower edges of a long plastic sheet were bent at right angles to form a tab, and the shaft of the nail was held and connected to the slot formed at the end of the tab. This is known (for example, see Japanese Patent Publication No. 46-4040).

Furthermore, in order to easily drive nails with the rear part of the nailer lifted upwards, there are connecting nails that are connected in advance by arranging the nails in parallel rather than perpendicularly to the direction of extension of the connecting member. Are known.

By the way, in the above-mentioned diagonally connected nail, as shown in FIG. 2, the shaft portion 2a of the nail 2 must be inserted obliquely into the slot 5 of the tab 4 which extends horizontally to the plastic sheet 3. In this case, although the inner wall surface of the slot 5 is formed vertically, since the nail is inserted into the nail shaft 2a, the inner wall surface of the slot 5 of the tab 4 is in line contact with the nail shaft 2a, and the slot 5 is in line contact with the nail shaft 2a. Since the contact area between the nail 5 and the nail shaft portion 2a is very small, the holding force of the nail 2 becomes unstable. Therefore, this connection structure causes the nail to fall off the connection member within the nail packaging container or the magazine of the nail gun.

(Technical Problems of the Invention) The present invention solves the above-mentioned drawbacks and provides a connecting nail that holds the nail diagonally to the connecting member made of a plastic sheet, and provides sufficient holding force to hold the nail against the connecting member. The technical problem is to provide a connection structure for diagonally connected nails that can prevent accidental falling off.

(Means for Solving the Problems) In order to solve the above problems, the connection structure of the diagonally connected nails according to the present invention includes a plurality of nail shaft holding tabs along the upper and lower edges of a long plastic sheet. In a diagonally connected nail that is bent and formed, and the nail shaft of the nail is inserted into the slot formed in the tab and held diagonally, a hardening resin is applied to the slot of the tab, and the nail shaft is inserted into the slot formed in the tab. It is characterized in that the gap formed between the outer peripheral surface and the inner wall surface of the slot is filled with the above-mentioned curable resin.

(Operations and Effects of the Invention) According to the above-described structure, the hardened resin completely fills the gap between the inner wall surface of the slot of the tab and the outer circumferential surface of the nail shaft. The contact area between the slot that holds the nail shank and the nail shank increases, and therefore the nail retention force increases.
Nails can be effectively prevented from falling off from the connecting member.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

In the figure, the symbol A indicates a diagonally connected nail. This diagonal connecting nail A has a long connecting member 1 and a plurality of nails 2,
2, 2... are connected diagonally, and the connecting member 1
is constructed by bending and forming a plurality of nail shaft holding tabs 4, 4, 4... along the upper and lower edges of a long plastic sheet 3, and the diagonal connecting nail A is formed by bending and forming a plurality of nail shaft holding tabs 4, 4, 4, etc. along the upper and lower edges of a long plastic sheet 3. The shaft portions 2a of the nails 2 are inserted into slots 5 formed in each tab 4 of the nails 1 and held diagonally in parallel.

Next, a curable resin is applied to the slot 5 of the tab 4, and the curable resin 6 is filled into the gap formed between the outer peripheral surface of the nail shaft portion 2a and the inner wall surface of the slot 5. .

As described above, in the diagonally connected nail A, since the curable resin 6 is completely filled in the gap between the inner wall surface of the slot 5 of the tab 4 and the outer peripheral surface of the nail shaft portion 2a, As a result, the contact area between the slot 5 that holds the nail shank 2a and the nail shank 2a becomes larger, and the holding force of the nail 2 increases, so that the nail 2 is effectively prevented from falling off from the connecting member 1. Can be done.

When applying a hardening resin to the slot of the tab of the connecting member, any method may be used, but for example, in order to reduce the nail driving resistance, the connecting nail is immersed in an acrylic resin bath and the nail is hardened. Since the above-mentioned resin film is formed on the tip of the shaft part, by using an acrylic hardening resin during this work, the slot of the tab of the above-mentioned connecting member is filled with the hardening resin at the same time. be able to.
