最初に、本実施形態に係るガス圧接部の測定具（以下、単に測定具ともいう）を用いて測定できる測定項目について説明する。図１〜図５は鉄筋ガス圧接部の測定対象を示す正面図または断面図であり、図１は膨らみの軸方向長さ，膨らみの直径，膨らみの高さ、図２は圧接部の軸偏心量、図３は圧接部の軸折れ曲がり角度、図４は圧接面のずれ量、図５は割れ部の深さ及び幅を示す図である。   First, measurement items that can be measured using the measuring tool (hereinafter also simply referred to as a measuring tool) of the gas pressure contact portion according to the present embodiment will be described. 1 to 5 are front views or cross-sectional views showing objects to be measured at the reinforcing bar gas pressure contact portion, FIG. 1 is the axial length of the bulge, the diameter of the bulge, the height of the bulge, and FIG. 2 is the axial eccentricity of the pressure contact portion. 3 is a diagram showing the axial bending angle of the pressure contact portion, FIG. 4 is a diagram showing the displacement amount of the pressure contact surface, and FIG. 5 is a diagram showing the depth and width of the crack portion.

鉄筋のガス圧接法は、たとえば図１に示すように建築物等で用いられる補強用鉄筋５，５の先端を互いに突き合わせ、軸方向ＡＸに圧縮力を加えながら接合部分を加熱して軟化させることで２本の鉄筋５，５を接合する方法である。接合された圧接部５２にはそれぞれの鉄筋先端が軟化してできた、概ね球状をなす膨らみが形成される。この膨らみの形状を測定することで接合強度等が評価される。   In the gas pressure welding method for reinforcing bars, for example, as shown in FIG. 1, the ends of reinforcing reinforcing bars 5 and 5 used in a building or the like are brought into contact with each other, and the joining portion is heated and softened while applying a compressive force in the axial direction AX. In this method, the two reinforcing bars 5 and 5 are joined. The joined pressure contact portion 52 is formed with a generally spherical bulge formed by softening the tip of each reinforcing bar. The bonding strength and the like are evaluated by measuring the shape of the bulge.

図１に示すように、圧接部５２の膨らみの軸方向の長さＬとは、左右の鉄筋５，５の胴部５１（鉄筋の円筒状の側面をいう。）と圧接部５２の膨らみとの交点の軸方向ＡＸの長さを言い、圧接部５２の膨らみの直径Ｄとは、圧接部５２の膨らみの、軸方向ＡＸに直交する方向（以下、圧接部５２の径方向ＲＡとも言う。）における直径を言い、圧接部５２の膨らみの高さＨとは、左右何れか一方の鉄筋５の胴部５１と圧接部５２の膨らみの頂点５３との、径方向ＲＡの長さを言う。 As shown in FIG. 1, the axial length L of the bulge of the press contact portion 52 is the body portion 51 (referring to the cylindrical side surface of the rebar) of the left and right rebars 5 and 5 and the bulge of the press contact portion 52. The swell diameter D of the press contact portion 52 is a direction perpendicular to the axial direction AX of the swell of the press contact portion 52 (hereinafter also referred to as a radial direction RA of the press contact portion 52). The bulge height H of the pressure contact portion 52 is the length in the radial direction RA between the body portion 51 of the left or right reinforcing bar 5 and the bulge vertex 53 of the pressure contact portion 52.

また、圧接部５２の軸偏心量Ｃとは、図２に示すように、左右の鉄筋５，５の軸５４，５４の、圧接部５２における径方向ＲＡの長さを言い、圧接部５２の軸折れ曲がり角度αとは、図３に示すように、左右の鉄筋５，５の軸の圧接部５２における鋭角側の角度を言う。 Further, as shown in FIG. 2, the axial eccentricity C of the pressure contact portion 52 means the length of the shafts 54, 54 of the left and right reinforcing bars 5, 5 in the radial direction RA in the pressure contact portion 52.

また、圧接面のずれ量Ｘとは、左右の鉄筋５，５の実際の圧接面５５と、膨らみの軸方向長さの中点５６との、軸方向ＡＸにおける長さを言う。つまり、目視にて実際の圧接面５５を確認する一方で、図１に示した膨らみの軸方向長さの中点５６を求め、これらの軸方向のずれ量を測定する。 Further, the displacement amount X of the pressure contact surface refers to the length in the axial direction AX between the actual pressure contact surface 55 of the left and right reinforcing bars 5 and 5 and the midpoint 56 of the axial length of the bulge. That is, while visually checking the actual pressure contact surface 55, the midpoint 56 of the axial length of the bulge shown in FIG. 1 is obtained, and the amount of deviation in these axial directions is measured.

また、圧接部５２に生じた割れ部５７の幅Ｗとは、図５に示すように割れ部５７の延在方向に対する幅を言い、割れ部５７の深さとは、同図に示すように圧接部５２の表面５８から軸５４へ向かう深さを言う。 Further, the width W of the cracked portion 57 generated in the pressure contact portion 52 means the width in the extending direction of the cracked portion 57 as shown in FIG. 5, and the depth of the cracked portion 57 is the pressure welded as shown in FIG. The depth from the surface 58 of the part 52 toward the shaft 54 is said.

The fourth scale 41 is used when the first contact portion 15 of the measurement tool body 1 and the third contact portion 42 at the lower end of the third slide ruler plate 4 are aligned in the X-axis direction. It is a scale which makes the lower end of the 1st ruler part 11 of the main body 1 zero, Comprising: It is graduated at intervals of 1 mm along the Y-axis direction.

第３スライド定規板４の下端には、Ｘ軸に平行に加工された第３当接部４２が形成され、上述した測定項目の測定時には、この第３当接部４３が鉄筋５の圧接部５２の頂点５３に当接するように、たとえば板を切断したままの状態とされている。 A third abutting portion 42 processed in parallel to the X axis is formed at the lower end of the third slide ruler plate 4, and this third abutting portion 43 serves as a pressure contacting portion of the reinforcing bar 5 when measuring the measurement items described above. For example, the plate is kept cut so as to abut on the vertex 53 of 52.

楔状測定具６は、楔状に形成されたステンレス板からなるもので、図６に示すように、回転軸６１によって測定具本体１に対して回転可能に装着され、測定時には同図に示す位置から時計回りに９０°回転させて用いられる。この楔状測定具６の一方の主面には、図８Ａに示すように、圧接部５２の割れ部５７の幅を測定するための第５目盛６１が付される一方で、反対の主面には、図８Ｂに示すように、圧接部５２の割れ部５７の深さｄを測定するための他の第５目盛６２が付されている。すなわち、図８Ａに示す幅の目盛６１は、楔状測定具６の幅ｗと同じ値とされた目盛であり、図８Ｂに示す深さの目盛６２は、楔状測定具６の先端からの長さとされた目盛である。 The wedge-shaped measuring tool 6 is made of a stainless steel plate formed in a wedge shape. As shown in FIG. 6, the wedge-shaped measuring tool 6 is rotatably mounted on the measuring tool body 1 by a rotating shaft 61, and from the position shown in FIG. Used by rotating 90 ° clockwise. As shown in FIG. 8A, a fifth scale 61 for measuring the width of the cracked portion 57 of the press contact portion 52 is attached to one main surface of the wedge-shaped measuring tool 6, while the opposite main surface is provided with the main surface. As shown in FIG. 8B, another fifth scale 62 for measuring the depth d of the cracked portion 57 of the press-contact portion 52 is attached. 8A is a scale having the same value as the width w of the wedge-shaped measuring tool 6, and the depth scale 62 shown in FIG. 8B is the length from the tip of the wedge-shaped measuring tool 6. It is a scale that was made.

なお、第１スライド定規板２と第３スライド定規板４を測定具本体１に対して装着するには、図９Ｂ、図９Ｃに示すように、ボルト７ａとナット７ｂの間にスプリングワッシャ７ｃを挟んで装着することが好ましい。また、第２スライド定規板３を第１スライド定規板２に対して装着する場合も、図９Ｄに示すように、ボルト７ａとナット７ｂの間にスプリングワッシャ７ｃを挟んで装着することが好ましい。 In order to attach the first slide ruler plate 2 and the third slide ruler plate 4 to the measuring instrument main body 1, as shown in FIGS. 9B and 9C, a spring washer 7c is provided between the bolt 7a and the nut 7b. It is preferable to put it on both sides. Further, when the second slide ruler plate 3 is attached to the first slide ruler plate 2, it is preferable to attach the spring washer 7c between the bolt 7a and the nut 7b as shown in FIG. 9D.

次に、本実施形態の測定具を用いて図１〜図５に示す各測定項目を測定する手順を説明する。 Next, a procedure for measuring each measurement item shown in FIGS. 1 to 5 using the measurement tool of the present embodiment will be described.

まず、膨らみの軸方向長さＬを測定するには、図９Ａに示すように、測定具本体１の第１当接部１５を左側の鉄筋５の圧接部５２の一方端５２ａに当接させ、ボルト７ａを緩めながら第１スライド定規板２を長孔１６に沿って移動させつつ、２つの基準線１７，２５を合わせる。そして、第２スライド定規板３の第２当接部３１を右側の鉄筋５の圧接部５２の他方端５２ｂに当接させる。そして、このときの第１スライド定規板２の左端が示す第１目盛１３の目盛を読み取る。同図の例では４５ｍｍとなるが、これが膨らみの軸方向長さＬとなる。なお、第３スライド定規板４は使用しないので同図に示すように圧接部５２と緩衝しない位置に退避させておく。 First, in order to measure the axial length L of the bulge, as shown in FIG. 9A, the first contact portion 15 of the measuring tool body 1 is brought into contact with one end 52a of the pressure contact portion 52 of the left reinforcing bar 5. The two reference lines 17 and 25 are aligned while moving the first slide ruler plate 2 along the long hole 16 while loosening the bolt 7a. Then, the second contact portion 31 of the second slide ruler plate 3 is brought into contact with the other end 52 b of the pressure contact portion 52 of the right reinforcing bar 5. And the scale of the 1st scale 13 which the left end of the 1st slide ruler board 2 at this time shows is read. In the example of the figure, it is 45 mm, but this is the axial length L of the bulge. Since the third slide ruler plate 4 is not used, the third slide ruler plate 4 is retracted to a position where it does not buffer with the press contact portion 52 as shown in FIG.

ここで仮に、左右の鉄筋５，５の軸５４，５４が偏心していると、図１１に示すように第２スライド定規板３が第１スライド定規板２に対してＹ軸方向に移動することになるので、同時に第１スライド定規板２の第３目盛２１を読み取れば、それが圧接部の軸偏心量Ｃとなる。図１１に示す例では５ｍｍとなる。 Here, if the shafts 54 and 54 of the left and right rebars 5 and 5 are eccentric, the second slide ruler plate 3 moves in the Y-axis direction with respect to the first slide ruler plate 2 as shown in FIG. Therefore, if the third scale 21 of the first slide ruler plate 2 is read at the same time, it becomes the axial eccentricity C of the press contact portion. In the example shown in FIG.

膨らみの直径Ｄを測定するには、図１０に示すように測定具本体１の第１当接部１５の右側端部を左側の鉄筋５の圧接部５２の頂点５３に当接させ、ボルト７ａを緩めながら第１スライド定規板２を長孔１６に沿って移動させつつ、第２スライド定規板３の第２当接部３１の左側端部を圧接部５２の頂点５３に当接させる。そして、このときの第１スライド定規板２の左端が示す第１目盛１３の目盛を読み取る。同図の例では４５ｍｍとなるが、これが膨らみの直径Ｄとなる。なお、第３スライド定規板４は使用しないので同図に示すように圧接部５２と緩衝しない位置に退避させておく。 In order to measure the diameter D of the bulge, as shown in FIG. 10, the right end portion of the first contact portion 15 of the measuring tool body 1 is brought into contact with the apex 53 of the pressure contact portion 52 of the left reinforcing bar 5, and the bolt 7a. While moving the first slide ruler plate 2 along the long hole 16, the left end of the second contact portion 31 of the second slide ruler plate 3 is brought into contact with the apex 53 of the pressure contact portion 52. And the scale of the 1st scale 13 which the left end of the 1st slide ruler board 2 at this time shows is read. In the example of the figure, it is 45 mm, but this is the diameter D of the bulge. Since the third slide ruler plate 4 is not used, the third slide ruler plate 4 is retracted to a position where it does not buffer with the press contact portion 52 as shown in FIG.

圧接部５２の軸折れ曲がり角度αを測定するには、図１２に示すように測定具本体１の第１当接部１５を左側の鉄筋５の胴部５１に当接させる一方で、ボルト７ａを緩めながら第１スライド定規板２を長孔１６に沿って移動させる。そして、支点２２ａを中心に第１スライド定規板２を回転させ、第２スライド定規板３の第２当接部３１を右側の鉄筋５の胴部５１に当接させる。なおこのとき、圧接部５２の膨らみは関係ないので、測定具本体１の第１当接部１５や第２スライド定規板３の第２当接部３１は、左右それぞれの鉄筋５の胴部５１に当接させればよい。 In order to measure the axial bending angle α of the pressure contact portion 52, the first abutting portion 15 of the measuring tool main body 1 is brought into contact with the trunk portion 51 of the left reinforcing bar 5 as shown in FIG. The first slide ruler plate 2 is moved along the long hole 16 while being loosened. Then, the first slide ruler plate 2 is rotated around the fulcrum 22a, and the second contact portion 31 of the second slide ruler plate 3 is brought into contact with the body portion 51 of the right reinforcing bar 5. At this time, since the bulge of the pressure contact portion 52 is irrelevant, the first contact portion 15 of the measuring tool main body 1 and the second contact portion 31 of the second slide ruler plate 3 are the body portions 51 of the left and right reinforcing bars 5, respectively. What is necessary is just to contact | abut.

そして、このときの第１スライド定規板２の基準線２４が示す第２目盛１４の目盛を読み取る。同図の例では４°となるが、これが圧接部の軸折れ曲がり角度αとなる。なお、第３スライド定規板４は使用しないので同図に示すように圧接部５２と緩衝しない位置に退避させておく。 And the scale of the 2nd scale 14 which the reference line 24 of the 1st slide ruler board 2 at this time shows is read. In the example of the figure, it is 4 °, but this is the axial bending angle α of the press contact portion. Since the third slide ruler plate 4 is not used, the third slide ruler plate 4 is retracted to a position where it does not buffer with the press contact portion 52 as shown in FIG.

膨らみの高さＨを測定するには、図１３に示すように測定具本体１の第１当接部１５を左側の鉄筋５の胴部５１に当接させ、ボルト７ａを緩めながら第１スライド定規板２を長孔１６に沿って移動させつつ、第２スライド定規板３の第２当接部３１を右側の鉄筋５の胴部５１に当接させたのち、第３スライド定規板４のボルト７ａを緩めながら当該第３スライド定規板４を長孔４３に沿ってＹ軸方向に移動させつつ第３当接部４２を圧接部５２の頂点５３に当接させる。 To measure the height H of the bulge, as shown in FIG. 13, the first abutting portion 15 of the measuring instrument main body 1 is brought into contact with the trunk portion 51 of the left reinforcing bar 5 and the first slide is loosened while loosening the bolt 7a. While the ruler plate 2 is moved along the long hole 16, the second abutting portion 31 of the second slide ruler plate 3 is brought into contact with the trunk portion 51 of the right reinforcing bar 5, and then the third slide ruler plate 4 is moved. The third abutting portion 42 is brought into contact with the apex 53 of the press contact portion 52 while the third slide ruler plate 4 is moved in the Y-axis direction along the long hole 43 while loosening the bolt 7a.

そして、このときの測定具本体１の第１定規部１１の下端が示す第４目盛４１の目盛を読み取る。同図の例では１６ｍｍとなるが、これが膨らみの高さＨとなる。 And the scale of the 4th scale 41 which the lower end of the 1st ruler part 11 of the measuring tool main body 1 at this time shows is read. In the example of the figure, it is 16 mm, but this is the height H of the bulge.

圧接面のずれ量Ｘを測定するには、図１４に示すように、図９Ａにて説明した膨らみの軸方向長さＬを測定する場合と同様、まず測定具本体１の第１当接部１５を左側の鉄筋５の圧接部５２の一方端５２ａに当接させ、第２スライド定規板３の第２当接部３１を右側の鉄筋５の圧接部５２の他方端５２ｂに当接させる。 In order to measure the displacement amount X of the pressure contact surface, as shown in FIG. 14, first, as in the case of measuring the axial length L of the bulge described with reference to FIG. 15 is brought into contact with one end 52 a of the pressure contact portion 52 of the left reinforcing bar 5, and the second contact portion 31 of the second slide ruler plate 3 is brought into contact with the other end 52 b of the pressure contact portion 52 of the right reinforcing bar 5.

そして、このときの第１スライド定規板２の左端が示す第１目盛１３を読み取って膨らみの軸方向長さＬを測定する。 And the 1st scale 13 which the left end of the 1st slide ruler board 2 at this time reads is read, and the axial direction length L of a bulge is measured.

この状態で、第３スライド定規板４のボルト７ａを緩めながら当該第３スライド定規板４を長孔４３に沿ってＹ軸方向に移動させつつ第３当接部４２の左端を、目視により観察された圧接面５５に当接させる。そして、このときの第３スライド定規板４の左端が示す第１目盛１３を読み取る。 In this state, the left end of the third contact portion 42 is visually observed while the third slide ruler plate 4 is moved along the long hole 43 in the Y-axis direction while loosening the bolt 7a of the third slide ruler plate 4. The pressed pressure contact surface 55 is brought into contact. And the 1st scale 13 which the left end of the 3rd slide ruler board 4 at this time shows is read.

第１スライド定規板２の左端が示す第１目盛１３の読みがＬ、第４スライド定規板４の左端が示す第１目盛の読みがＬ１であるとき、圧接面のずれ量Ｘは、Ｘ＝Ｌ／２−Ｌ１の絶対値として求められる。たとえば、図１４に示す例では、Ｌ＝５１ｍｍ、Ｌ１＝２６ｍｍであるから、Ｘ＝０．５ｍｍとなる。 When the reading of the first scale 13 indicated by the left end of the first slide ruler plate 2 is L and the reading of the first scale indicated by the left end of the fourth slide ruler plate 4 is L1, the displacement amount X of the press contact surface is X = It is obtained as an absolute value of L / 2−L1. For example, in the example shown in FIG. 14, since L = 51 mm and L1 = 26 mm, X = 0.5 mm.

ここで、圧接面５５が目視で観察できない場合には、下記のような評価をすることもできる。すなわち、測定具本体１と第１スライド定規板２とを用いて圧接部の軸方向長さＬを測定する手順は同じであるが、第３スライド定規板４の左端を圧接面５５に当接させることに代えて膨らみの頂点５３に当接させる。そして、そのときの第３スライド定規板４の左端が示す第１目盛１３を読み取り、これをＬ１として、圧接面のずれ量Ｘ＝Ｌ／２−Ｌ１を求める。 Here, when the press contact surface 55 cannot be visually observed, the following evaluation can be performed. That is, the procedure for measuring the axial length L of the press contact portion using the measuring tool body 1 and the first slide ruler plate 2 is the same, but the left end of the third slide ruler plate 4 is brought into contact with the press contact surface 55. It is made to contact | abut to the vertex 53 of a bulge instead of making it. And the 1st scale 13 which the left end of the 3rd slide ruler board 4 at that time shows is read, this is made into L1, and displacement amount X = L / 2-L1 of a press-contact surface is calculated.

一方、圧接部５２に割れ部５７が生じているときは、割れ部５７の深さｄや幅Ｗを測定する。割れ部５７の幅Ｗを測定するには、図１５に示すように楔状測定具６の先端を、割れ部５７の幅方向と平行になる方向で割れ部５７に挿入し、割れ部５７の表面が示す図８Ａの第５目盛６１を読み取る。読み取った数値が割れ部の幅Ｗとなる。 On the other hand, when the crack part 57 has arisen in the press-contact part 52, the depth d and the width W of the crack part 57 are measured. In order to measure the width W of the cracked portion 57, the tip of the wedge-shaped measuring tool 6 is inserted into the cracked portion 57 in a direction parallel to the width direction of the cracked portion 57 as shown in FIG. 8A is read. The read numerical value is the width W of the cracked portion.

また、割れ部５７の深さｄを測定するには、楔状測定具６の先端を、割れ部５７の長手方向と平行になる方向で割れ部５７に挿入し、割れ部５７の表面が示す図８Ｂの第５目盛６２を同図に示す白抜き矢印方向から読み取る。読み取った数値が割れ部の深さｄとなる。 Further, in order to measure the depth d of the cracked portion 57, the tip of the wedge-shaped measuring tool 6 is inserted into the cracked portion 57 in a direction parallel to the longitudinal direction of the cracked portion 57, and the surface of the cracked portion 57 is shown. The fifth scale 62 of 8B is read from the direction of the white arrow shown in FIG. The read numerical value is the depth d of the cracked portion.

以上のとおり、本実施形態の測定具によれば、一つの測定具によって、ガス圧接された鉄筋の圧接部の、膨らみの軸方向長さＬ、膨らみの直径Ｄ、圧接部の軸偏心量Ｃ、圧接部の軸折れ曲がり角度α、膨らみの高さＨ及び圧接面のずれ量Ｘ、並びに割れ部の幅Ｗ及び深さｄを測定することができる。 As described above, according to the measuring tool of the present embodiment, the axial length L of the bulge, the diameter D of the bulge, and the axial eccentricity C of the press-contacting part of the pressure-welded part of the gas-welded rebar are measured by one measuring tool. The axial bending angle α, the bulge height H, the displacement amount X of the pressure contact surface, and the width W and depth d of the cracked portion can be measured.
