Abstract

PROBLEM TO BE SOLVED: To improve holding force upon powerfully bonding a strong split nail or strong pointed nail and a specific counterpart member altogether by preconfining a bonding agent in a thin filmy state in a tubular opened leg part of a split nail or a notched groove part installed in a leg part outer boundary of a pointed nail, and breaking down the thin film in a moment the nail is driven into the specific counterpart member. SOLUTION: A bonding agent 4 is sealed in an inner part of a leg part 3 of a shank 2 of a strong split nail in a thin film 5. A head part 1 of the nail is beaten, driving it into a counterpart member Q, and internal pressure in this bonding agent 4 is raised up instantaneously and thereby this bonding agent 4 is sealed therein, and when the thin film 5 is broken, simultaneously the bonding agent 4 passes through an interrelated clearance among the leg part 3 and a contact surface of the counterpart member Q as well as a mounting member P, and thus it is penetrated and spread widely. If the nail is fully driven into the counterpart member Q, the bonding agent 4 left behind in the leg part 3 simultaneously with the leg open of this leg part 3, is penetrated and spread in every clearance, filling up the bonding agent in the interrelated contact surface among the nail and the counterpart member Q as well as the mounting member P and every clearance to the full. With this constitution, the mounting member P is powerfully and positively lockable to the counterpart member Q.

In addition, even if the thickness is shorter than the total thickness of the mounting member and the mating member, the nail is normally opened by modifying the tip of a nail described in JP-A-8-170620 having a large holding force (pull-out resistance). By changing the tip of a strong open nail (claims 1 to 3) having a greater holding force than a leg nail, and a tip nail (hereinafter referred to as a normal nail), the holding force is higher than that of a normal nail. The present invention relates to a strong pointed nail which is greatly enlarged and is effective for the above-mentioned unique mating member.

Description of the Related Art Conventionally, there has been no suitable driving nail for the above-mentioned unique mating member, and a wooden screw having a length penetrating through the mating member and penetrating to the back side has been used to increase the holding force. However, the emergence of the recently developed ordinary leg nails has eliminated the lack of holding force for a considerable range of unique mating members. However, problems still remain depending on the type and thickness of the unique partner member as described below. In addition, the conventional ordinary leg nail has a very small holding force for a unique mating member, and cannot be used at all because the holding force is still insufficient even if the tip penetrates the mating member and penetrates to the back side.

特異相手部材用としては到底使用不可能である。When the mating member is soft wood, soft plywood, a soft compression board, or a foam concrete board having low strength, the holding force may be insufficient even with a normally open nail. If the mating member is hard and strong but thin, such as a cement-based molded board, the back surface of the mating member will be broken in a conical shape with the length of a normally open nail with the necessary holding power, If the length of the ordinary leg nail is shortened in order to prevent the damage, there is a problem of insufficient holding power, so that the use of the ordinary leg nail is considerably limited. Of course, in the case of the ordinary pointed nail, the holding power is insufficient unless the nail is longer than the ordinary open nail, so that it cannot be used at all for a thin special mating member.

The present invention relates to an open-leg nail (normally open nail) according to Japanese Patent Application Laid-Open No. Hei 8-170620 developed as a nail which can be effectively used by being driven into a unique mating member such as a compression molded board which is hard to work with a normal nail (ordinary nail). While the holding power of the leg nails has been further strengthened, it provides a powerful open-leg nail compatible with the newly developed soft thin special mating member (new fireproof board), which has recently emerged as a lightweight and low-cost popular version. It is possible to realize strong pointed nails that greatly exceed the holding power of ordinary pointed nails, which could not be used at all, so conventional screw nails with poor workability with no easy driving nails or other fasteners are found. In the construction industry, which has been working, it is possible to expect a great effect on improving work efficiency and ensuring quality. In particular, in the recent Great Hanshin-Awaji Earthquake and other earthquakes that have occurred in various places, it is expected to greatly help to prevent the collapse of wooden buildings, which have been heavily damaged, and to make it easier to use fireproof boards for fire prevention and fire spread prevention.

いう効果もある。Further, as will be apparent from FIGS. 1 and 2, when the strong open nail or the strong point nail of the present invention is used, the nail and its surrounding mounting members and mating members are used. Are glued to each other without any gaps, and the nailing part automatically becomes a completely watertight structure.Therefore, it is possible to prevent rainwater intrusion into the conventional nailing structure without additional work such as special waterproof treatment. The disadvantages are completely eliminated. This is a great advantage that can be particularly noted in waterproofing measures for the outer walls and roofs of buildings, and in combination with the great holding power of the nail of the present invention, two birds per stone are required to prevent rain leakage and scattering of roof tiles during a typhoon during a typhoon. The effect can be expected, and the unpleasant indoor floor noise (the fricative noise between the nail and the joist striking the floorboard), which was difficult to countermeasure in the past, can be improved by using the powerful spiked nail of the present invention. Since the adhesive is automatically filled in between, the floor noise can be completely eliminated.

An adhesive which reacts with a component gas (for example, water vapor) of the outside air and is solidified in a concave portion of a cut groove provided on an outer periphery of a leg of a pointed nail having a sharp tip of a leg of the nail. However, the surface of the adhesive reacts with the outside air to contain the unreacted adhesive inside, and the thin film is instantaneously destroyed by the impact pressure generated when the nail is driven in. The adhesive sealed inside flows out, permeates and diffuses into the contact surface between the nail and the driving partner, and then reacts with the component gas of the outside air adhered to the contact surface to bond the two. nail.
