Description
【0001】0001
この考案は、ALCなどの軟質材に木材などを固定するために用いるねじ釘に 関する。 This idea is suitable for screw nails used to fix wood etc. to soft materials such as ALC. related.
【0002】0002
ALCに木材を固定するための手段としては、プラグ、アンカーによる取付け 、釘の打ち込みによる取付け、接着剤による取付け、ねじ釘による取付けがある 。 Methods for fixing wood to ALC include installation using plugs and anchors. , installation by driving nails, installation by adhesive, and installation by screw nails. .
【0003】 ところで、プラグ、アンカーによる取付けは、ALC及び木材に下穴を穿設し た後プラグ、アンカーを拡開させるため、下穴の穿設に手間がかかり、施工コス トが高くつくという問題がある。0003 By the way, installation using plugs and anchors requires drilling pilot holes in the ALC and wood. After the plug and anchor are expanded, drilling a pilot hole is time-consuming and construction cost is high. The problem is that it is expensive.
【0004】 釘による取付けは、脆弱なALCに対する釘の抜止効果が弱く、木材の固定強 度が得られないという問題がある。0004 When attaching with nails, the nails have a weak effect on preventing the fragile ALC from falling out, and the fixing strength of the wood is poor. There is a problem of not being able to obtain a degree.
【0005】 接着剤による固定は、接着剤の硬化までに時間がかかり、施工能率が悪いと共 に、固定強度も弱いという問題がある。[0005] Fixing with adhesive takes time for the adhesive to harden, resulting in poor installation efficiency. Another problem is that the fixing strength is weak.
【0006】 ねじ釘による取付けは、木材からALCにねじ込むだけでよいので、施工性が よく、固定強度も得られるので、先に述べた他の取付け手段に比べ、ALC用と して最も適している。[0006] Installation with screws and nails is easy as it only requires screwing from the wood to the ALC. It also provides good fixing strength, so it is more suitable for ALC than other mounting methods mentioned above. It is the most suitable.
【0007】 図4乃至図7は従来のALC用ねじ釘の異なった例を示している。[0007] 4 to 7 show different examples of conventional ALC screws.
【0008】 図4のAとBに示す第1の例のねじ釘1は、軸部2の先端に尖端3と後端に頭 部4を設け、軸部2の外周面全長に連続するねじ5を設けた構造になっている。[0008] The screw nail 1 of the first example shown in A and B of FIG. It has a structure in which a portion 4 is provided, and a screw 5 is provided that continues along the entire length of the outer circumferential surface of the shaft portion 2.
【0009】 図6のA、Bに示したねじ釘1は、軸部2の外周に設けたねじ5を途中までと し、頭部4側に無ねじ部6を形成した構造になっている。[0009] The screw nail 1 shown in A and B of FIG. However, it has a structure in which a non-threaded portion 6 is formed on the head 4 side.
【0010】 図7のA、Bに示したねじ釘1は、図6と同様のねじ釘において頭部4の押さ え面に木材切削刃7を形成した構造になっている。0010 The screw nail 1 shown in FIGS. 7A and 7B is similar to that shown in FIG. It has a structure in which a wood cutting blade 7 is formed on the cutting surface.
【0011】[0011]
先ず、図4に示したねじ釘1は、木材11からALC12へのねじ込み時にお いて、図5のAのように、ねじ5の先端が木材11を貫通するとき、ねじ5の先 端傾斜によって木材11の裏面に突部13が押し出され、図5Bのようにねじ釘 1の進入にともない突部13は押し広げられ、この突部13の拡開によるバリが 図5Cの如くALC12と木材11の間に隙間14を生じさせ、図4Bのように 木材11をALC12の面に密着させて締結することができないという問題があ る。 First, the screw nail 1 shown in FIG. 5, when the tip of the screw 5 penetrates the wood 11, the tip of the screw 5 The protrusion 13 is pushed out on the back side of the wood 11 due to the edge slope, and the screw nail is pushed out as shown in FIG. 5B. As the protrusion 1 enters, the protrusion 13 is pushed wider, and the burr caused by the expansion of the protrusion 13 is A gap 14 is created between the ALC 12 and the wood 11 as shown in Fig. 5C, and as shown in Fig. 4B. There is a problem that the wood 11 cannot be fastened in close contact with the surface of the ALC 12. Ru.
【0012】 また、木材11をALC12に向けて押えても、ねじ5は全ねじで木材11に も螺合しているため、一旦生じた隙間14を埋めることはできない。0012 Also, even if you press the wood 11 toward the ALC 12, the screw 5 is fully screwed into the wood 11. Since both are screwed together, it is impossible to fill the gap 14 once created.
【0013】 次に、図6のねじ釘1は、頭部4側の無ねじ部6が木材11を貫通するため、 ねじ込み状態において、頭部4による押圧で木材11のバリは押え付けられて解 消し、ALC12に木材11を密着させることができるが、頭部4が木材11に 沈み込むとき、ねじ5に引抜き方向の過大な力がかかり、頭部4を沈めるのが困 難になると共に、図6Bのように頭部4を完全に沈めようと更に回転を与えると 、同図一点鎖線のように、ALC12内にあるねじ5が自らの螺道を破壊し、空 廻りが発生して木材11の固定が不能になるという問題がある。[0013] Next, in the screw nail 1 of FIG. 6, since the non-threaded part 6 on the head 4 side penetrates the wood 11, In the screwed state, the burrs on the wood 11 are held down and released by the pressure from the head 4. The wood 11 can be brought into close contact with the ALC 12, but if the head 4 is attached to the wood 11, When sinking, excessive force is applied to the screw 5 in the pulling direction, making it difficult to sink the head 4. It becomes difficult to rotate the head 4 in order to completely submerge it as shown in Figure 6B. , As shown by the dashed line in the figure, the screw 5 inside the ALC 12 breaks its own spiral and becomes empty. There is a problem in that the wood 11 cannot be fixed due to rotation.
【0014】 更に図7のねじ釘1は、頭部4の切削刃7で木材11を切削するため、図6の ねじ釘1よりも木材11に対する頭部4の沈み込みは良くなるが、木材11が予 想以上に硬質の場合、図6のねじ釘1と同様、ねじ5が自らの螺道を破壊して空 廻りが発生するという問題がある。[0014] Furthermore, the screw nail 1 shown in FIG. 7 cuts the wood 11 with the cutting blade 7 of the head 4, so the screw nail 1 shown in FIG. The head 4 sinks into the wood 11 better than the screw nail 1, but the wood 11 is If it is harder than expected, screw 5 will break its own spiral and become empty, similar to screw nail 1 in Figure 6. There is a problem that rotation occurs.
【0015】 そこでこの考案は、上記のような従来のねじ釘にあった問題点を解決するため 、ALCに対して木材を密着させた状態で固定できると共に、空廻りのない締結 状態が得られるねじ釘を提供することを課題としている。[0015] Therefore, this idea was developed to solve the problems with conventional screw nails as mentioned above. , it is possible to fix the wood in close contact with the ALC, and it can be fastened without twisting. Our goal is to provide screws that can be used in a variety of conditions.
【0016】[0016]
上記のような課題を解決するため、この考案は、軸部の先端に尖端と後端に頭 部を設けたねじ釘において、軸部の外周に、途中の無ねじ部を挟んで先端側の第 1のねじと後端側の第2のねじを分離して設け、第1のねじに対して第2のねじ は、第1のねじのつる巻き線の延長線上からずれた位置に設けられている構成を 採用したものである。 In order to solve the above problems, this invention has a pointed end at the tip of the shaft and a head at the rear end. For screw nails with a threaded section, the outer periphery of the shank is sandwiched with the non-threaded section in between, and the tip end side The first screw and the second screw on the rear end side are provided separately, and the second screw is connected to the first screw. is a configuration provided at a position offset from the extension line of the helical wire of the first screw. This is what was adopted.
【0017】[0017]
木材からALCに向けてねじ込むと、先ず第1のねじが進入し、次に無ねじ部 が木材を貫通し、この後第2のねじが木材にねじ込まれる。 When screwing from wood toward ALC, the first screw enters first, then the unthreaded part passes through the wood, after which a second screw is screwed into the wood.
【0018】 第2のねじは第1のねじのつる巻き線の延長線上からずれた位置に設けられて いるので、木材に第1のねじで形成された螺道と異なった部分に第2のねじが螺 入するので、この第2のねじによって木材はALCに向けて押され、木材裏面の バリは押圧解消され、木材はALCの表面に密着する。[0018] The second screw is installed at a position offset from the extension line of the helical wire of the first screw. Therefore, the second screw is threaded into the wood in a different part from the spiral formed by the first screw. This second screw pushes the wood towards the ALC, causing the back side of the wood to The burr is released and the wood adheres to the surface of the ALC.
【0019】 頭部を木材に沈み込ませるときは、ドライバーの押込力と木材に螺入した第2 のねじの引込みによって行なわれるため、ALC内に螺入した第1のねじ部分に 過大な負荷がかからず、空廻りの発生がない。[0019] When sinking the head into the wood, use the pushing force of the screwdriver and the second screw screwed into the wood. This is done by retracting the screw, so the first screw threaded into the ALC No excessive load is applied and no spinning occurs.
【0020】[0020]
以下、この考案の実施例を添付図面の図1乃至図3に基づいて説明する。 Embodiments of this invention will be described below with reference to FIGS. 1 to 3 of the accompanying drawings.
【0021】 図1のように、ねじ釘21は、所定の長さを有する円軸状の軸部22と、この 軸部22の先端に設けた尖端23と、軸部22の後端に設けた頭部24と、軸部 22の外周面で中間部分に形成した無ねじ部25を挟んで先端側に設けた第1の ねじ26及び頭部側に設けた第2のねじ27とで構成されている。[0021] As shown in FIG. 1, the screw nail 21 includes a circular shaft portion 22 having a predetermined length, and a circular shaft portion 22 having a predetermined length. A pointed end 23 provided at the tip of the shaft 22, a head 24 provided at the rear end of the shaft 22, and a shaft A first screw provided on the distal end side with a non-threaded portion 25 formed in the middle portion on the outer circumferential surface of 22 sandwiched therebetween. It is composed of a screw 26 and a second screw 27 provided on the head side.
【0022】 前記第1のねじ26は、ALCに螺入する部分であり、所定の耐引抜強度が得 られる長さに設定され、尖端23から無ねじ部25の範囲に一定のピッチで設け られている。[0022] The first screw 26 is a part that screws into the ALC, and has a predetermined pull-out strength. The threads are set to a length that is equal to or larger than the thread length, and are provided at a constant pitch in the range from the tip 23 to the non-threaded part 25. It is being
【0023】 第2のねじ27は、頭部24寄りの位置に、木材の厚みに見合う長さの範囲で 設けられ、第1のねじ26と同じ方向の螺旋になっている。[0023] The second screw 27 is located near the head 24 and has a length that matches the thickness of the wood. The first screw 26 has a spiral in the same direction as the first screw 26 .
【0024】 上記第1のねじ26と第2のねじ27の位置関係は、図2に示すように、第1 のねじ26のつる巻き線Aの延長線上に対して第2のねじ27がずれた位置にな るように設定されている。[0024] The positional relationship between the first screw 26 and the second screw 27 is as shown in FIG. The second screw 27 is in a position shifted from the extension line of the helical wire A of the screw 26. is set to
【0025】 この考案のねじ釘は上記のような構成であり、ALC12に対して木材11を 固定するために使用され、ALC12に重ねた木材11に尖端23を押し当て、 頭部24に係合したドライバーでねじ釘21に押込み力と回転を与える。[0025] The screw nail of this invention has the above structure, and the wood 11 is attached to the ALC 12. It is used for fixing and presses the tip 23 against the wood 11 stacked on the ALC 12, A driver engaged with the head 24 applies pushing force and rotation to the screw nail 21.
【0026】 ねじ釘21は先ず軸部22の第1のねじ26が木材11からALC12に螺入 し、木材11を貫通するとき尖端23によって木材11の裏面にバリが発生する 。[0026] First, the first screw 26 of the shaft portion 22 of the screw nail 21 is screwed into the ALC 12 from the wood 11. However, when penetrating the wood 11, burrs are generated on the back surface of the wood 11 by the tip 23. .
【0027】 ALC12内に対する軸部22の進入により無ねじ部25が木材11を貫通し 、更に軸部22の進入が進むと第2のねじ27の先端が木材11に当接する。[0027] As the shaft portion 22 enters into the ALC 12, the non-threaded portion 25 penetrates the wood 11. As the shaft portion 22 advances further, the tip of the second screw 27 comes into contact with the wood 11.
【0028】 第2のねじ27の先端が木材11に当接すると、図3のように、木材11はA LC12に向けて押され、バリが押圧により解消し、木材11の裏面がALC1 2に密着し、隙間の発生がなくなる。[0028] When the tip of the second screw 27 comes into contact with the wood 11, as shown in FIG. The wood 11 is pushed towards LC12, the burr is removed by the pressure, and the back side of the wood 11 is moved to ALC1. 2, and there are no gaps.
【0029】 第2のねじ27は木材11を十分に押圧した後、木材11に螺入する。この第 2のねじ27は、第1のねじ26におけるつる巻き線Aの延長線上からずれた位 置に設けられているので、第1のねじ26によって形成された木材11の螺道に 対して第2のねじ27は異なった位置に螺入することになり、従って第2のねじ 27は木材11に対してゆるみのない強固なねじ込み状態となる。[0029] The second screw 27 is screwed into the wood 11 after sufficiently pressing the wood 11. This first The second screw 27 is located at a position offset from the extension line of the helical wire A on the first screw 26. Since the spiral path of the wood 11 formed by the first screw 26 On the other hand, the second screw 27 will be screwed into a different position, and therefore the second screw 27 will be screwed into a different position. 27 is firmly screwed into the wood 11 without loosening.
【0030】 第2のねじ27が木材11に螺入したのち頭部24が木材11の表面に凹入す べく進み、頭部24の凹入はドライバーによる押圧と、第2のねじ27による木 材11への螺入部分の引込みとにより行なわれるため、脆弱なALC12内にあ る第1のねじ26に過大な負担をかけることはなく、従ってねじ釘21はALC 12の破壊による空廻りの発生がなく、木材11を強固に固定化できる。[0030] After the second screw 27 is screwed into the wood 11, the head 24 is recessed into the surface of the wood 11. The head 24 is recessed by pressing with a screwdriver and by tightening the wood with the second screw 27. This is done by pulling the screwed part into the material 11, so it is possible to There is no excessive load on the first screw 26, so the screw nail 21 The wood 11 can be firmly fixed without the occurrence of empty rotation due to the destruction of the wood 12.
【0031】 なお、頭部24の木材表面への凹入時に抵抗が小さくなるよう、頭部24の押 圧面に図1で示したように切削刃28を形成するようにしてもよい。[0031] Note that the head 24 is pressed so that the resistance is reduced when the head 24 is depressed into the wood surface. A cutting edge 28 may be formed on the pressure surface as shown in FIG. 1.
【0032】[0032]
以上のように、この考案によると、軸部の先端側に第1のねじと頭部側に第2 のねじをその間に無ねじ部を介在させて分離状に設け、第1のねじと第2のねじ の位置関係を、第1のねじのつる巻き線の延長線上に対して第2のねじをずれた 位置に設けたので、ねじ込み時に第2のねじはその先端で木材を押し込むことに なるので、ALCに対して木材を密着した状態で確実に固定化することができる 。 As described above, according to this invention, there is a first screw on the tip side of the shaft portion and a second screw on the head side. The screws are provided separately with a non-threaded part interposed therebetween, and the first screw and the second screw are separated. The positional relationship of the second screw is shifted from the extension line of the helical wire of the first screw. Since the second screw is set in the right position, the tip of the second screw will push into the wood when screwing in. Therefore, it is possible to securely fix the wood in close contact with the ALC. .
【0033】 また、第2のねじは木材に形成された第1のねじによる螺道と異なる位置に螺 入するので、第2のねじは木材に対してゆるみのない強固な螺入状態となり、木 材の表面に頭部を沈み込ませるとき、第2のねじが木材に螺入する部分で引込む ので、脆弱なALC内に位置する第1のねじに大きな負担をかけることがなく、 従ってALCの破壊による空廻りの発生が防止でき、木材の固定が強固に行なえ る。[0033] Also, the second screw is threaded in a different position from the first thread formed in the wood. As the second screw is inserted into the wood, it is firmly screwed into the wood with no loosening. When sinking the head into the surface of the wood, pull in the part where the second screw screws into the wood. Therefore, there is no need to place a large burden on the first screw located within the fragile ALC. Therefore, it is possible to prevent the occurrence of hollow rotation due to the destruction of ALC, and the wood can be firmly fixed. Ru.
