Description

本考案は、例えば、護岸又は堤防工事等で使用する大型石材（例えば、１〜５ｍ）を連結する場合に使用する石材連結用アンカーに関する。 The present invention relates to an anchor for connecting stones used when connecting large stones (for example, 1 to 5 m) used for revetment or embankment, for example.

例えば、特許文献１に記載されているように、本出願人は先に自然石からなる複数の石垣石を上下左右に並べ、これらの自然石を支持棒によって連結した護岸壁を提案した。そして、自然石を連結する支持棒４９（一例）を図４に示すが、テーパーピン５０を入れ込むことによってその実質径が拡大する拡径部５１を一方に他方には雌ねじ５２が形成された連結部５３を有する金具５４を２組と、両側に雌ねじ５２が螺合可能な雄ねじ５５、５６が形成され、直径は金具５４と略同一のロッド材５７とを用意し、ロッド材５７の両側に金具５４をそれぞれねじ込んだものであった。 For example, as described in Patent Document 1, the present applicant previously proposed a revetment wall in which a plurality of stone wall stones made of natural stones are arranged vertically and horizontally and these natural stones are connected by a support bar. A support rod 49 (one example) for connecting natural stones is shown in FIG. 4, and a female thread 52 is formed on the other side of the enlarged diameter portion 51 whose substantial diameter is increased by inserting the taper pin 50. Two sets of metal fittings 54 having a connecting portion 53 and male screws 55 and 56 to which female screws 52 can be screwed are formed on both sides. A rod material 57 having a diameter substantially the same as that of the metal fitting 54 is prepared. The metal fittings 54 were respectively screwed in.

特開２００１−５５７１７号公報JP 2001-55717 A

しかしながら、この従来技術に係る支持棒４９においては、雌ねじ５２を有する金具５４及び雄ねじ５５、５６を有するロッド材５７を用意することは極めて手間であり、更に、金具５４及びロッド材５７を鉄材によって構成した場合には長期間風雨に曝すとねじの部分が錆びて雌ねじ５２と雄ねじ５５、５６が螺合しにくくなるという問題があった。
更には、ロッド材５７の端部を縮径して雄ねじ５５、５６を形成しているので、支持棒４９の強度は雄ねじ５５、５６の部分で決まり、強度不足となる場合があった。
本考案はかかる事情に鑑みてなされたもので、製造が容易でしかも十分な強度を有する石材連結用アンカーを提供することを目的とする。 However, in the support rod 49 according to this prior art, it is extremely troublesome to prepare the metal fitting 54 having the female screw 52 and the rod material 57 having the male screws 55 and 56. Furthermore, the metal fitting 54 and the rod material 57 are made of iron. In the case of the construction, there has been a problem that when exposed to wind and rain for a long period of time, the screw portion rusts and the female screw 52 and the male screws 55 and 56 are difficult to be screwed together.
Furthermore, since the end portions of the rod member 57 are reduced in diameter to form the male screws 55 and 56, the strength of the support rod 49 is determined by the portions of the male screws 55 and 56, and the strength may be insufficient.
The present invention has been made in view of such circumstances, and an object thereof is to provide a stone connecting anchor that is easy to manufacture and has sufficient strength.

前記目的に沿う本考案に係る石材連結用アンカーは、隣り合って配置された２つの大型石材を連結するための石材連結用アンカーであって、管状部分に複数の縦割りを入れて形成された拡径部を両側に有する直線材と、該直線材の拡径部に押し込んで該拡径部の実質直径を広げるテーパーピンとを有する。 A stone connecting anchor according to the present invention that meets the above-described object is a stone connecting anchor for connecting two large stones arranged adjacent to each other, and is formed by inserting a plurality of vertical divisions into a tubular portion. A linear member having enlarged diameter portions on both sides; and a taper pin that is pushed into the enlarged diameter portion of the linear material to increase the substantial diameter of the enlarged diameter portion.

本考案に係る石材連結用アンカーにおいて、前記直線材は中実棒からなって両側に前記管状部分が形成されている場合、前記直線材はパイプからなっている場合のいずれであってもよい。
また、前記拡径部の内側端には開放端に拡径するテーパーが形成されていることが好ましく、これによってテーパーピンが容易に嵌入する。
そして、前記複数の縦割りは直角方向に形成された４つの縦割りからなるのが製作上好ましいが、３又は５又は６以上であってもよい。 In the stone connecting anchor according to the present invention, the straight member may be a solid rod and the tubular portions are formed on both sides, or the straight member may be a pipe.
Moreover, it is preferable that the taper which expands to an open end is formed in the inner end of the said enlarged diameter part, and a taper pin fits easily by this.
The plurality of vertical divisions are preferably four vertical divisions formed in a perpendicular direction, but may be 3 or 5 or 6 or more.

本考案に係る石材連結用アンカーは、直線材の両側に拡径部が一体的に形成されているので、従来のようにねじを用いて連結する必要がなく、製作が容易になる。
また、連結部分がないので、施工時の強度が増すと共に、全体的な石材の連結強度が増す。 The stone connecting anchor according to the present invention is integrally formed with the enlarged diameter portions on both sides of the straight member, and therefore, it is not necessary to connect using screws as in the conventional case, and the manufacturing is easy.
Moreover, since there is no connection part, while the intensity | strength at the time of construction increases, the connection strength of the whole stone material increases.

続いて、添付した図面を参照しつつ、本考案を具体化した実施の形態につき説明し、本考案の理解に供する。

Here, FIG. 1A is a plan view of a stone connecting anchor according to an embodiment of the present invention, FIG. 1B is a front view of the same stone connecting anchor, and FIG. 2 is a use state of the same stone connecting anchor. FIG. 3A is a plan view of a stone connecting anchor according to another embodiment of the present invention, and FIG. 3B is a front view of the stone connecting anchor.

本考案の一実施の形態に係る石材連結用アンカー１０は、鉄又はステンレス材からなって、管状部分１０ａに複数の縦割り（この実施の形態では４つ）１１を入れて形成された拡径部１２を両側に有する直線材１３と、拡径部１２に押し込んで拡径部１２の実質直径を広げる２つのテーパーピン１４（片側しか図示せず）とを有する。以下、これらについて詳しく説明する。 A stone connecting anchor 10 according to an embodiment of the present invention is made of iron or stainless steel, and is formed by inserting a plurality of vertical divisions (four in this embodiment) 11 into a tubular portion 10a. It has a linear member 13 having a portion 12 on both sides, and two taper pins 14 (only one side is shown) that are pushed into the enlarged diameter portion 12 to increase the actual diameter of the enlarged diameter portion 12. These will be described in detail below.

直線材１３の長さは、例えば、０．５〜４ｍ、その直径は１０〜１００ｍｍ程度となって、両側には直径（外径）の２〜５倍程度の深さの穴１５が形成されている。穴１５の内径は直径の１／２〜３／４程度となっている。穴１５の内側端部は面取りされて、開放端に拡径するテーパー１６ａが形成されている。なお、両側の穴１５が形成されている部分以外の直線材１３は中実棒からなっている。 The length of the linear member 13 is, for example, 0.5 to 4 m, the diameter thereof is about 10 to 100 mm, and holes 15 having a depth of about 2 to 5 times the diameter (outer diameter) are formed on both sides. ing. The inner diameter of the hole 15 is about 1/2 to 3/4 of the diameter. The inner end of the hole 15 is chamfered to form a taper 16a that expands to the open end. The straight members 13 other than the portions where the holes 15 on both sides are formed are solid bars.

穴１５の部分には穴１５の略底部まで達する縦割り１１が形成されている。縦割り１１の幅は出来るだけ小さい方が好ましいが、通常は０．５〜３ｍｍ程度となっている。この実施の形態では縦割り１１の数は均等角度（即ち、９０度）で４つであるが、３つ又は５つ以上の縦割りを形成してもよい。また、縦割りは傾斜角度０を超え４５度以内の範囲でスパイラル状に形成してもよい。スパイラル状に形成すると、穴１５の長さに対して切り込みによって分割された片の長さが増すので、分割された片に対する荷重が緩和される。 A vertical split 11 is formed at the hole 15 so as to reach the bottom of the hole 15. The width of the vertical division 11 is preferably as small as possible, but is usually about 0.5 to 3 mm. In this embodiment, the number of the vertical divisions 11 is four at an equal angle (that is, 90 degrees), but three or five or more vertical divisions may be formed. Further, the vertical division may be formed in a spiral shape in a range exceeding the inclination angle 0 and within 45 degrees. When formed in a spiral shape, the length of the piece divided by cutting is increased with respect to the length of the hole 15, so that the load on the divided piece is reduced.

一方、テーパーピン１４は市販のもので十分であるが、穴１５の平均直径の１．２〜１．５倍程度の最大径を有して、テーパーピン１４の軸心に対して５〜３０度程度の傾斜角（即ち、稜線と軸心とのなす角度）を有する円錐台形状をしている。 On the other hand, although the commercially available taper pin 14 is sufficient, it has a maximum diameter of about 1.2 to 1.5 times the average diameter of the holes 15 and is 5-30 with respect to the axis of the taper pin 14. It has a frustoconical shape having an inclination angle of about 60 degrees (that is, an angle formed between the ridge line and the axis).

この石材連結用アンカー１０を使用する場合には、図２に示すように、隣り合って配置された連結しようとする大型石材１６と大型石材１８及び大型石材１７と大型石材１８に対して連通穴１９、２０を形成する。連通穴１９は大型石材１８を貫通するが、大型石材１６は貫通しない構造となっている。また、連通穴２０は大型石材１８は貫通するが大型石材１７は貫通しない構造となっている。なお、大型石材１６、１７は地盤に対してアンカー２１、２２で固定されている。 When the stone connecting anchor 10 is used, as shown in FIG. 2, the large stone 16 and the large stone 18 and the large stone 17 and the large stone 18 which are arranged adjacent to each other are communicated with each other. 19 and 20 are formed. The communication hole 19 penetrates the large stone 18 but the large stone 16 does not penetrate. The communication hole 20 has a structure in which the large stone 18 penetrates but the large stone 17 does not penetrate. The large stones 16 and 17 are fixed to the ground by anchors 21 and 22.

まず、所定長さ（即ち、連通穴１９、２０の深さの例えば７０〜９０％）の石材連結用アンカー１０を用意する。連通穴１９、２０の直径は石材連結用アンカー１０より１〜３ｍｍ程度大きくしておく。石材連結用アンカー１０の下端部にテーパーピン１４を固定させた状態で、連通穴１９（又は２０）に入れ込み、上部から石材連結用アンカー１０と同一直径の棒（又は管）Ａを挿入し、ハンマーで棒の端部を叩き、下部のテーパーピン１４を穴１５内に押し込み、拡径部１２を拡径させる。これによって、石材連結用アンカー１０は大型石材１６（又は１７）に形成されている連通穴１９（又は２０）から抜けないようになる。 First, the stone connecting anchor 10 having a predetermined length (ie, 70 to 90% of the depth of the communication holes 19 and 20) is prepared. The diameters of the communication holes 19 and 20 are about 1 to 3 mm larger than the stone connecting anchor 10. In a state where the taper pin 14 is fixed to the lower end portion of the stone connecting anchor 10, it is inserted into the communication hole 19 (or 20), and a rod (or pipe) A having the same diameter as that of the stone connecting anchor 10 is inserted from above. The end of the rod is hit with a hammer and the lower taper pin 14 is pushed into the hole 15 to expand the diameter-expanded portion 12. As a result, the stone connecting anchor 10 is prevented from coming out of the communication hole 19 (or 20) formed in the large stone 16 (or 17).

次に、連通穴１９（又は２０）の上部から別のテーパーピン１４を落とし込み、上部から棒Ａで叩き込み、上側の拡径部１２を拡径させる。これによって、石材連結用アンカー１０の上側は大型石材１８に固定される。以上の操作によって、大型石材１６と大型石材１８及び大型石材１７と大型石材１８が連結される。 Next, another taper pin 14 is dropped from the upper part of the communication hole 19 (or 20), and it is struck with the stick A from the upper part, so that the upper enlarged diameter part 12 is expanded. Thus, the upper side of the stone connecting anchor 10 is fixed to the large stone 18. The large stone 16 and the large stone 18 and the large stone 17 and the large stone 18 are connected by the above operation.

次に、図３に示す本考案の他の実施の形態に係る石材連結用アンカー２５について、前記実施の形態に係る石材連結用アンカー１０との相違点について説明する。
この石材連結用アンカー２５は、中実の棒ではなくて管（パイプ）によって直線材３２全体が形成されている。従って、両側部には当然管状部分が形成されている。そして、両側端部に、その直径の２〜５倍の縦割り２６が形成され、その部分に拡径部２７を形成している。そして、拡径部２７の周囲には複数の環状溝２８が形成されている。この環状溝２８は縦割り２６によって形成された拡径片２９の外側に形成され、その数は３〜５個（複数）程度で十分である。環状溝２８の深さは管の厚みの０．０５〜０．３倍程度が好ましい。なお、縦割り２６の底部に一致する部分にも環状溝２８を形成するのが好ましい。このようにして直線材３２が形成され、この直線材３２の端部、即ち、拡径部２７にテーパーピン１４を差し込んだ場合、容易に拡径する。
この石材連結用アンカー２５の使用方法については、石材連結用アンカー１０と同じである。 Next, differences between the stone connecting anchor 25 according to another embodiment of the present invention shown in FIG. 3 and the stone connecting anchor 10 according to the above embodiment will be described.
The stone connecting anchor 25 is formed not by a solid rod but by a pipe (pipe) so that the entire linear member 32 is formed. Therefore, of course, tubular portions are formed on both sides. And the vertical division 26 of 2-5 times the diameter is formed in the both-ends part, and the enlarged diameter part 27 is formed in the part. A plurality of annular grooves 28 are formed around the enlarged diameter portion 27. The annular groove 28 is formed on the outer side of the enlarged diameter piece 29 formed by the longitudinal division 26, and the number of the annular grooves 28 is enough to be about 3 to 5 (plural). The depth of the annular groove 28 is preferably about 0.05 to 0.3 times the thickness of the tube. In addition, it is preferable to form the annular groove 28 in a portion that coincides with the bottom of the vertical division 26. In this way, the linear member 32 is formed, and when the taper pin 14 is inserted into the end portion of the linear member 32, that is, the enlarged diameter portion 27, the diameter is easily increased.
The stone connecting anchor 25 is used in the same manner as the stone connecting anchor 10.

前記実施の形態においては、具体的数字を用いて本考案に係る石材連結用アンカーを説明したが、本考案の要旨を変更しない範囲での数値変更は可能である。 In the said embodiment, although the stone connection anchor based on this invention was demonstrated using the specific number, the numerical value change in the range which does not change the summary of this invention is possible.
