Description

The invention relates to the production of fasteners.

Known nail, consisting of a pointed rod and a hat on the blunt end [1].

The objective of the invention is to save metal in the manufacture of especially large nails.

The technical result of solving the problem is achieved by the fact that in the nail, consisting of a pointed rod and a hat on the blunt end, the rod is hollow, and the hat is made overhead fixed / removable from the rod. The detachable hat is equipped with a holder.

In Fig.1 shows a nail with a patch fixed head, side view; figure 2 is a view of figure 1 - bottom; figure 3 shows an embodiment of the invoice fixed head; figure 4 shows a patch removable hat with a holder:

The nail (Figs. 1 and 2) consists of a pointed rod 1 and a hat 2 at the blunt end 3. The rod is made in the form of a metal tube 4 having a cavity 5. A solid body is located in the cavity 6. The hat is made overhead, wedging with a strong impact on it (arrow A in figure 1) with the formation of one-piece connection. The inseparable connection of the cap and the rod can also be achieved by performing thread 7 on each of them (Fig. 3), followed by a strong blow to the cap (along arrow A in Fig. 1) in order to “break” the thread. The hat may be removable (figure 4). The removable cap may be provided with a holder 8.

A nail, for example, of circular cross section, with a diameter of 50 mm and a length of 500 mm, is made as follows.

A tube 4 is made from steel (brass, aluminum), which is sharpened at one end by a crimping method, obtaining a preform in the form of a rod 1 having a cavity 5. The cavity is filled, for example, with an expanding cement-sand mixture, which is kept (28 days) until it forms solid concrete tube 6.

A steel hat 2 is made of steel (brass, aluminum) in three versions: a) with a proppant (FIGS. 1 and 2); b) with a screw thread 7, while on the outer side of the blunt end 3 of the rod perform a response thread (figure 3); C) with a holder 8 (figure 4).

In the material to be bonded (wood, plastic, metal, stone), a channel is pre-drilled, for example, with a diameter of 45-50 mm, into which a pointed rod is hammered with strong blows to the patch hat. When this blunt end of the rod is deformed with the formation of one-piece connection (Fig.1-3). In the case of using a removable cap, only the shaft is driven into the channel to the required depth. The hat is used repeatedly. The cap holder (figure 4) facilitates its movement from one rod to another.

The invention allows to save metal in the manufacture of especially large nails.
