するボルトや開脚釘が知られるが、これらは保持
力が弱く、特に上記の軽量発泡コンクリートにあ
つては充分なアンカー効果が得られず抜けやすい
という難点があつた。 In general, bolts and nails with split legs that expand as they are driven are known as anchoring objects that have a split tip, but these have weak holding power, especially when it comes to the above-mentioned lightweight foam concrete. There was a problem that a sufficient anchor effect could not be obtained and it was easy to slip out.
そこで、上記のアンカーボルトや開脚釘に代わ

45057号等）等の２部材からなるものが提案され
ている。 Therefore, as an alternative to the above-mentioned anchor bolts and spread nails, a plastic sleeve is inserted into a pre-prepared drill hole, and this sleeve is expanded outward by screwing in or driving a nail into it. (Japanese Patent Publication No. 48-21015, British Patent No. 1330114, etc.), by driving a metal sleeve with an expanded piece at the lower end, and then inserting a pin etc. into this sleeve and driving it. A device that expands the above-mentioned expansion piece (Utility Model Publication No. 4502, Utility Model Publication No. 4502, Utility Model Application No. 48-
No. 45057, etc.), which consists of two members, have been proposed.

問題があつた。Problems to be solved by the invention However, although the conventionally proposed two-member structure has a good anchoring function and a large holding force against lightweight foamed concrete,
The former method, which uses a plastic sleeve, requires a three-step cumbersome operation including drilling holes, and has poor workability.
Further, the latter method using a metal sleeve requires a two-step pressing operation, which has the problem of poor workability and insufficient adhesion between the sleeve and the pin etc.

頭部７に開口して割溝９の上部に達する同心状の
挿入孔１０を備えている。尚、挿入孔１０の孔底
１０ａは釘本体１の軸部２の下端２ａに対応する
すりばち状になつている。 Reference numeral 5 denotes a metal sleeve, in which a flange-shaped head 7 is integrally formed at the upper end of a cylindrical body 6, and a lower end 8 of the body 6 is cut diagonally from both sides in the radial direction to form a wedge shape. Expansion pieces 8a, 8a are formed by grooves 9 formed into a tapered shape and cut in the axial direction from the central lower end of the wedge shape in the lower end portion 8,
A concentric insertion hole 10 that opens in the head 7 and reaches the upper part of the split groove 9 is provided. The bottom 10a of the insertion hole 10 has a dome shape corresponding to the lower end 2a of the shaft portion 2 of the nail body 1.
しかして、スリーブ５の挿入孔１０は、その深
さＬが釘本体１の軸部２の全長l1より小でかつリ
ブ４下の軸部２の長さl2と同一もしくはそれより
も大に設定され、またその口径Ｄが軸部２の径d1

が完了する。 The driving operation is performed by inserting the nail head 3 of the nail body 1 into the sleeve 5 as shown in FIG. 5A.
All you have to do is press it with a hammer or the like. This driving force is transmitted to the sleeve 5 through the abutting portions of each step 4a of the nail body 1 and the peripheral edge of the insertion hole 10, and
The lightweight foam concrete layer 1 is guided by the tapered lower end 8 of the sleeve 5 in an integrated state with the sleeve 5.
2, as shown in FIG. 5B. 5C, the head 7 of the sleeve 5 is attached to the member 1.
2, the entry of the sleeve 5 is stopped due to the resistance, but by further applying pressure to the nail head of the nail body 1, the rib 4 is crushed and the gap between the shaft portion 2 and the insertion hole 10 is closed. The lower end 2a of the shaft portion 2 presses the hole bottom 10a of the insertion hole 10, and this pressing causes both expansion pieces 8a, 8a of the lower end portion 8 of the sleeve 5 to be driven in. is pushed outward across the split groove 9, and finally, as shown in FIG. 5D, the lower surface of the nail head 3 comes into contact with the head 7 of the sleeve 5, completing the driving.
