DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below based on an embodiment shown in the drawings.

1, 2 and 3, the outer cylinder 1 has a concentric round flange 1b at the upper end of a cylindrical main body 1a made of steel, and the lower end is bent to form a pointed portion 1d. In addition, holes 1c are provided at two diametrically opposed locations near the pointed portion 1d. The hole 1c of the outer cylinder is a long hole that is long in the axial direction of the outer cylinder.

The columnar body 2a of the steel shaft 2 is inserted from the upper end of the outer cylinder 1 and has a concentric round head 2b at the upper end, and at the boundary between the shaft main body 2a and the head 2b, the head side is located on the head side. A widening taper surface 2c is formed. A positioning recess 2d is formed on the lower end surface of the shaft 2. Then, an adhesive (or pressure-sensitive adhesive) 3 is applied to the outer periphery of the columnar body 2a, and the shaft 2 is prevented from coming off by adhesion or friction with the inner surface of the cylindrical body 1a of the outer cylinder 1.

Further, on the outer circumference of the shaft 2, a plurality of circumferential projections 2e for sealing are formed by rolling. A rotating circular die is pressed against the rotating shaft, and plastic deformation causes circumferential ridge 2e.
(Height about 0.1 to 0.2 mm). Approximate size makes it easy to fit the outer cylinder 1, has a waterproof effect, and does not hinder the driving of the shaft 2.

The rod-shaped anchor member 4 is interposed between the lower end of the shaft 2 and above the pointed portion 1c, and the lower end faces the hole 1c of the outer cylinder 1. The anchor member 4 is made of a round wire made of steel, which is bent in an inverted U shape, and both ends 4a of the wire are on the lower side. The both ends 4a are bent so as to face the hole 1c of the outer cylinder 1. ing.

In the above, in FIG. 4, the exterior material A such as roof tile or wood board is attached to the surface of the lightweight cellular concrete base material B.
The case of fixing with the nail of the present invention will be described. In the state where the center hole of the cylindrical jig J is inserted in the shaft 2 of the fixture of the present invention, both of them are held by one hand. Next, when the hammer held by the other hand hits the head of the jig J and drives it, the outer cylinder 1 is driven up to the flange 1b and stops.

Next, when the head of the shaft 2 is hit with a hammer except for the jig J, the movement of the outer cylinder 1 is stopped by the flange 1b, so that the adhesive 3 is released and the shaft head 2b is released. Is driven up to the surface of the flange 1b of the outer cylinder 1. And
The anchor member 4 sequentially comes out from the hole 1c of the outer cylinder in the axial direction thereof and enters the inside of the base material B.

Here, the positioning recess 2 is formed on the lower end surface of the shaft 2.
Since there is d, the axes of the shaft 2 and the anchor member 4 substantially coincide with each other, and the anchor member 4 smoothly exits from the outer cylinder. Further, since the hole 1c is a long hole, strict accuracy is not required for positioning the tip of the anchor member 4 with respect to the hole. Moreover, hole 1
There is a case where the anchor member 4 goes out of the outer cylinder by being guided in the direction of the length of c, and in this case, the anchor member 4 has a balanced posture in the portion protruding from the outer cylinder. This creates an anchor that resists the pulling force. Also, the outer cylinder 1
The shaft 2 does not move in the outer cylinder until is completely driven.
Therefore, the anchor member 4 projects from the outer cylinder only after the outer cylinder 1 is hit, and the periphery of the driving layer is not undesirably destroyed.

Here, when the shaft 3 comes out of the outer cylinder 1 during handling, or when a force in the opposite direction acts on the shaft 2 due to the elastic restoring force of the anchor member 4 during the driving of the shaft 2, the adhesive 3 is To counter.

FIG. 4 shows another embodiment. The hole 1c of the outer cylinder is cut out on the upper side and bent inward to form a guide piece 1e, on which the lower end of the anchor member 4 is supported.

FIG. 5 shows another embodiment. A cylindrical guide member 5 is provided inside the lower portion of the outer cylinder 1 and between the pointed portion 1d and the hole 1c. The upper end of the guide member 5 is a flat surface that is substantially perpendicular to the axial direction of the outer cylinder 1. In this case, as shown in FIG. 6, the lower lower surface of the anchor member 4 receives a reaction force by the upper surface of the guide member 5 and is strongly pressed against the corner portion 5a of the upper peripheral edge of the guide member 5, so that the tip end of the anchor member 4 is pushed. Bends upwards. With the subsequent hammering, the upper surface of the portion where the anchor member 4 passes through the outer cylindrical hole 1c is also strongly pressed against the corner angle 1f of the outer cylindrical hole 1c. As a result, the anchor member exits from the outer cylinder in a state where it is strongly sandwiched between the upper and lower surfaces in the portion passing through the outer cylinder hole 1c, so that the anchor member is "squeezed" and bends in an upward arc shape. I will do it.

FIG. 6 shows still another embodiment. The lower end of the guide member 5 is a cusp and is replaced with the outer cylinder cusp 1d. That is, the guide member 51 is the cylindrical body 1 of the outer cylinder 1.
At the lower end of the cylindrical portion 51a that is concentric with a
b is integrally formed, and the upper end is a flat surface. A circular groove 51c is provided on the outer circumference of the columnar portion 51a, and the bent piece 1g at the lower end of the outer cylinder 1 is fitted into the circular groove 51c by caulking.

Further, as shown in FIG. 7, the outer cylinder 1 (most part or lower half part) is molded so as to have a plurality of concavo-convex lines along the axial direction, and the fixing force is increased. In this case, if the anchor member 4 is interposed between the opposing ridges and the holes 1c are provided in these portions, the anchor member 4 can be easily and reliably positioned with respect to the hole 1c. Further, in this case, when the outer diameter of the shaft 2 is slightly thickened to cause a "tightening margin",
The adhesive 3 can be omitted. Further, even when the outer cylinder 1 has a rectangular (square) cross-section as shown in FIG. 8, the adhesive 3 can be omitted by increasing the thickness of the shaft 2 to make a tight margin.

The anchor member 4 is replaced by the anchor member shown in FIGS.
As shown in FIG. 1, a l-shaped (lowercase alphabetic character) letter wire is bent outward at both ends, or
As shown in Nos. 2 and 13, a strip thin plate piece is cut along the length direction from the lower side to the front side and bent into a human-character shape (or a letter-shape). Alternatively, a J-shaped wire (not shown) may be used so that it exits from one hole of the outer cylinder. The anchor member 4 is formed integrally with the shaft 2 or is separately secured by an adhesive, welding, or the like.

As the anchor member, a usual material for nails is used. Also, if you use spring material such as stainless spring steel,
Since it is rich in elasticity, even if the positional relationship between the outer cylinder 1 and the anchor member is displaced due to an earthquake or the like, the original state is restored and the fixing strength is strong.

Further, as shown in FIG. 9 a, instead of the adhesive 3, several convex portions 3 are provided on the outer periphery of the columnar body 2 a at equal intervals in the circumferential direction, and this is the same as the inner surface of the outer cylinder 1. It will be the "close margin". Instead of the convex portion 3, an axial convex strip is arranged and provided in the circumferential direction. Further, these convex portions or ridges may be pressed (or hit) from the outer side of the outer cylinder 1 to be projected and molded on the inner side of the outer cylinder 1. Alternatively, as shown in FIG. 9, a circumferential groove 2c may be provided on the outer circumference of the shaft 2 and the ring packing 9 may be fitted therein. Alternatively, a diametrically expanded taper surface or a bulge surface is formed at the upper end of the shaft as shown in phantom in FIG. 9a.

When the shaft does not have a head, a sealant layer is applied on top of the shaft. In this case, after the shaft 2 is driven into the outer cylinder 1, the sealing material layer prevents the rainwater from entering. Further, the sealing material is attached to the lower part of the shaft 2 and the upper part of the anchor member 4. In addition, as a waterproofing means inside the outer cylinder 1, a rotary round die is pressed from the outside of the rotating outer cylinder 1 to form a sealing circumferential ridge on the inner circumference of the outer cylinder. Alternatively, FIG. 9a
A diametrically expanded taper surface or a bulge surface is formed at the upper end of the shaft as shown by the phantom line. Alternatively, as shown in FIG. 9, the ring packing 9 is interposed.

In FIG. 9a, the sleeve 11 is closely inserted into the outer periphery of the portion of the outer cylinder 1 that reaches the flange. The sleeve 11 is made of a synthetic resin molded product, and has an outer flange 11b at one end and a tapered taper surface 11c at the other end of the cylindrical body 11a. Therefore, when driving through the waterproof sheet,
Although the sticky substance of the waterproof sheet adheres to the tip of the outer cylinder 1 relatively well, it also adheres to the sleeve in a large amount, which increases the waterproof effect. The outer cylinder flange 1b is a donut-shaped plate separate from the cylinder body 1a,
The hole periphery of the donut-shaped plate is bent downward, one end of the cylinder main body is expanded and bent, and the bent part of the donut-shaped plate is squeezed in the cylinder main body with the donut-shaped plate fitted to the cylinder main body. It is fixed. Therefore, the flange is attached to the outer cylinder by a die and a press, which is suitable for mass production.

Although similar to FIG. 9a, the outer cylinder flange 1b is a donut-shaped plate separate from the cylinder body 1a, one end of the cylinder body is expanded and bent, and the donut-shaped plate is fitted to the cylinder body. The sleeve 11 may be inserted from the other end of the outer cylinder, and these parts may be combined. In this case, press equipment for attaching the flange to the cylinder body is not required. When the outer cylinder flange 1b is composed of a disc spring or a disc spring, it has a retaining effect by buffering.

The present invention can be applied to an extremely wide range of applications such as nails, drawing hooks, tatami hooks, and other member fixing tools.
In addition to the above, the material of the driven member is applied to wood wool cement board, wood, tatami mat and the like.

The present invention is not limited to the examples and embodiments described above, but includes various modifications without departing from the spirit and scope of the claims.

[0031]

According to the structure of the present invention, since the rod-shaped anchor member projects in the length direction from the tip of the rod from the side surface near the tip of the outer cylinder, the anchor member smoothly penetrates without breaking the layer. To do. Therefore, the stability of the base of the fixture is also good. In addition, since the tip of the fixing tool can be formed into a pointed shape, it is easy to drive and the layer is not broken undesirably. Moreover, since the thickness is determined by the outer cylinder and the shaft or the outer cylinder and the anchor member, the thickness can be made thinner than the conventional one, and it is easy to drive and the waterproof around the driven nail is also easy. Moreover, the pull-out proof strength can be freely designed by selecting the thickness, material strength and length of the anchor member.

Further, a convex portion is formed on the outer circumference of the shaft or the inner circumference of the outer cylinder, or an adhesive material is interposed between the outer circumference and the shaft or the anchor member, or a diameter-expanding tapered surface is provided at one end of the shaft. Alternatively, a bulge surface is formed. Therefore, the shaft is prevented from slipping out of the outer cylinder during handling or when a force in the opposite direction acts on the shaft due to the elastic restoring force of the anchor member.
