しかし、上述したような試験片の本体への固定の仕方では、試験片を取替えるたびにクランプによる横筋の着脱を繰返さなければならず、作業が煩雑となり、作業効率の低下を招く恐れがある。そればかりではなく、クランプによる横筋の、前記本体への固定が緩いと、せん断試験の測定中に横筋が回転してしまうため、正確にせん断強さを測定することができない、といった問題が生じる。   However, in the method of fixing the test piece to the main body as described above, it is necessary to repeat the attachment and detachment of the horizontal stripe by the clamp every time the test piece is replaced, and the work becomes complicated and the work efficiency may be reduced. Not only that, but if the transverse bars are loosely fixed to the main body by the clamp, the transverse bars rotate during the measurement of the shear test, so that the shear strength cannot be measured accurately.

この発明は上記のような種々の課題を解決することを目的としてなされたものであって、せん断試験の前後において試験片を容易に着脱することができ、さらにせん断試験中に、横筋が回転することなく測定することができる、試験片固定具を具備した、せん断測定機を提供することを目的とする。   The present invention has been made for the purpose of solving the various problems as described above. The test piece can be easily attached and detached before and after the shear test, and the transverse bar rotates during the shear test. An object of the present invention is to provide a shear measuring machine equipped with a test piece fixture that can be measured without any problems.

上記目的を達成するために、請求項１記載のせん断測定機は、縦筋と横筋を略直角に交差させて溶接した交差溶接部分を有する試験片の前記横筋を装置本体に試験片固定具を介して取付け、前記縦筋を前記装置本体に設けた引張手段により引張ることによって、該交差溶接部分におけるせん断強さを測定するせん断測定機において、前記試験片固定具が、前記装置本体に着脱自在に固定されるジョイントと、前記縦筋を下方へ垂下げつつ前記横筋の両側を載置する断面形状が略V字型の載置部とからなることを特徴としている。   In order to achieve the above object, a shear measuring machine according to claim 1 is characterized in that a test piece fixture is attached to a main body of the test piece having a cross-welded portion in which a vertical bar and a horizontal bar are crossed and welded at a substantially right angle. In the shear measuring machine that measures the shear strength at the cross welded portion by pulling the longitudinal bars by the pulling means provided on the apparatus main body, the test piece fixing tool is detachable from the apparatus main body. And a cross-sectional shape in which both sides of the horizontal stripe are placed while the vertical stripe is suspended downward, and a substantially V-shaped placement portion.

請求項２記載のせん断測定機は、前記略V字型の載置部が前記ジョイントと連結した本体枠に上下自在に嵌着され且つ表面に横溝を多数形成した鉛直移動板と、該鉛直移動板と向い合って傾斜する傾斜面の表面に横溝を多数形成し且つ前記本体枠に固定された載台とを具備することを特徴としている。   The shear measuring machine according to claim 2, wherein the substantially V-shaped mounting portion is fitted to a main body frame connected to the joint so as to freely move up and down and has a plurality of lateral grooves formed on a surface thereof, and the vertical movement A large number of lateral grooves are formed on the surface of the inclined surface inclined to face the plate, and a mounting base fixed to the main body frame is provided.

請求項３記載のせん断測定機は、前記載台が前記本体枠に着脱自在に固定されていることを特徴としている。   According to a third aspect of the present invention, there is provided the shear measuring machine, wherein the table is detachably fixed to the main body frame.

請求項１記載のせん断測定機は、前記試験片固定具が、前記装置本体に着脱自在に固定されるジョイントと、前記縦筋を下方へ垂下げつつ前記横筋の両側を載置する断面形状が略V字型の載置部とからなる。そのことにより、従来のように、前記横筋をクランプにより固定する必要がない。そのため、せん断試験を行う際に、前記試験片を前記試験片固定具に取付ける作業が、前記横筋を略V字型の前記載置部に載置するだけでよく、極めて単純であり、作業を効率的に行うことができる。   The shear measuring machine according to claim 1, wherein the test piece fixture has a joint that is detachably fixed to the apparatus main body, and a cross-sectional shape on which both sides of the horizontal bar are placed while the vertical bar is suspended downward. It consists of a substantially V-shaped mounting part. As a result, it is not necessary to fix the transverse stripes with a clamp as in the prior art. Therefore, when performing a shear test, the work of attaching the test piece to the test piece fixing tool is only required to place the transverse stripe on the substantially V-shaped mounting portion, and the work is extremely simple. Can be done efficiently.

請求項２記載のせん断測定機は、鉛直移動板、及び載台の傾斜面のそれぞれに、横溝が多数形成されている。そのことにより、せん断試験中に、前記横筋が回転することなく測定することができるので、正確にせん断強さを測定することができる。さらに、前記鉛直移動板が本体枠に上下自在に嵌着されていることにより、断面形状が略V字型の前記載置部により固定された前記横筋を、せん断試験後に取外す際には、前記横筋の一端部を上方へ引上げる。そうすることで、前記横筋の一部が前記横溝に噛み込んでいることから、該横筋と共に前記鉛直移動板が上方へ移動するため、容易に前記横筋を取外すことができる。さらに、前記載台は、前記鉛直移動板と向い合って傾斜する傾斜面の表面に横溝を多数形成している。そのことにより、太さの異なる前記横筋に対しても、前記試験片固定具を構成する各部位を交換する必要がなく使用することができるため、作業効率を向上することが可能となる。   The shear measuring machine according to claim 2 has a large number of transverse grooves formed on each of the vertical moving plate and the inclined surface of the mounting table. As a result, during the shear test, the transverse strength can be measured without rotating, so that the shear strength can be accurately measured. Furthermore, when the vertical movement plate is fitted to the main body frame so as to be freely movable up and down, the horizontal streak fixed by the mounting portion having a substantially V-shaped cross section is removed after the shear test, Pull up one end of the transverse muscle. By doing so, since a part of the transverse stripe is bitten in the transverse groove, the vertical moving plate moves upward together with the transverse stripe, so that the transverse stripe can be easily removed. Further, the table described above has a large number of lateral grooves formed on the surface of the inclined surface that is inclined to face the vertical moving plate. As a result, even for the transverse muscles having different thicknesses, it is possible to use the parts constituting the test piece fixture without having to be exchanged, thereby improving work efficiency.

請求項３記載のせん断測定機は、載台が本体に着脱自在に固定されていることにより、多数の前記横溝が、度重なるせん断試験により磨耗した際にも、容易に交換することが可能となる。   According to the third aspect of the present invention, since the mounting table is detachably fixed to the main body, it can be easily replaced even when a large number of the lateral grooves are worn by repeated shear tests. Become.

この発明のせん断測定機の最良の実施形態について以下図１に基づいて説明する。この実施例のせん断測定機Iは、試験片固定具１１が、前記せん断測定機Iに着脱自在に固定されるジョイント１２と、縦筋２を下方へ垂下げつつ横筋３の両側を載置する断面形状が略V字型の載置部１３と、前記略V字型の載置部１３が、前記ジョイント１２と連結した本体枠１４に上下自在に嵌着され且つ表面に横溝１５aを多数形成した鉛直移動板１６と、前記鉛直移動板１６と向い合って傾斜する傾斜面１７aの表面に横溝１５bを多数形成し且つ前記本体枠１４に着脱自在に固定された載台１７と、を具備している。   The best embodiment of the shear measuring machine of the present invention will be described below with reference to FIG. In the shear measuring instrument I of this embodiment, the test piece fixture 11 is placed on both sides of the horizontal bar 3 while the vertical bar 2 is hung downward and the joint 12 detachably fixed to the shear measuring machine I. The mounting portion 13 having a substantially V-shaped cross-section and the substantially V-shaped mounting portion 13 are fitted to the main body frame 14 connected to the joint 12 so as to freely move up and down, and a large number of lateral grooves 15a are formed on the surface. A plurality of lateral grooves 15b formed on the surface of the inclined surface 17a that is inclined to face the vertical moving plate 16 and is detachably fixed to the main body frame 14. ing.

前記本体枠１４は、図８に示すように、ジョイント１２によって図には示されていないせん断測定機Iへ着脱自在に固定される。そして、前記本体枠１４は、図８に示すように、前記ジョイント１２を取付ける上板１８と、前記上板１８の一端から鉛直方向に、該上板１８から離反する方向に形成された２本の柱体１９と、該２本の柱体１９の間に設けられた空間２０、及び２本の前記柱体１９の下端部から前記上板１８と略平行であって、同方向に設けられた底板２１からなる。さらに前記底板２１には、前記試験片１を構成する前記縦筋２を貫通するための貫通穴２２と、２本の前記柱体１９と相対するように前記底板２１の端部に形成された、前記載台１７を係止するための２つの係止片２３と、前記載台１７を螺接するためのボルト穴２４と、が設けられている。   As shown in FIG. 8, the main body frame 14 is detachably fixed to a shear measuring device I not shown in the drawing by a joint 12. As shown in FIG. 8, the main body frame 14 includes an upper plate 18 to which the joint 12 is attached, and two pieces formed in a direction perpendicular to one end of the upper plate 18 and away from the upper plate 18. The column body 19, the space 20 provided between the two column bodies 19, and the lower plate portions of the two column bodies 19 are substantially parallel to the upper plate 18 and provided in the same direction. The bottom plate 21. Further, the bottom plate 21 is formed at the end of the bottom plate 21 so as to face the through hole 22 for penetrating the vertical bars 2 constituting the test piece 1 and the two columnar bodies 19. Two locking pieces 23 for locking the table 17 and a bolt hole 24 for screwing the table 17 are provided.

また、底板２１に設けられた貫通穴２２は図８のような形状に限定されるものではなく、図１１に示すように、前記底板２１の端部にまで及ぶように形成された貫通穴２２aとしてもよい。このような貫通穴２２aとすれば、前記試験片１を前記載置部１３に載置する際に、上方から前記試験片１を構成する前記縦筋２を、前記貫通穴２２に貫通させる必要がない。すなわち、図１２に示すように、前記試験片１は、該試験片１を構成する前記縦筋２を、２つの前記係止片２３の間を通過するように前記貫通穴２２aを通り、前記試験片固定具１１の前方から、前記載置部１３に載置することができるため、作業性をさらに向上することができる。さらに、前記空間２０が設けられているため、せん断試験を行う際に、前記試験片固定具１１の前後左右どの方向からでも前記試験片１の状態を確認することができる。   Further, the through hole 22 provided in the bottom plate 21 is not limited to the shape as shown in FIG. 8, and as shown in FIG. 11, the through hole 22 a formed to reach the end of the bottom plate 21. It is good. With such a through hole 22a, when the test piece 1 is placed on the placement portion 13, the vertical bars 2 constituting the test piece 1 need to be passed through the through hole 22 from above. There is no. That is, as shown in FIG. 12, the test piece 1 passes through the through hole 22a so as to pass through the longitudinal bars 2 constituting the test piece 1 between the two locking pieces 23, and Since it can be mounted on the mounting portion 13 from the front of the test piece fixture 11, workability can be further improved. Furthermore, since the space 20 is provided, the state of the test piece 1 can be confirmed from any front, rear, left, or right direction of the test piece fixture 11 when performing a shear test.

前記鉛直移動板１６は、図１に示すように、前記本体枠１４に上下自在に嵌着され且つ表面に前記横溝１５aを多数形成している。前記鉛直移動板１６は、前記載台１７と共に、前記試験片１を構成する前記横筋３を載置するための、断面形状が略V字型となる前記載置部１３を構成している。さらに、前記載置部１３において載置される前記横筋３が、せん断測定時に回転することがないように、前記鉛直移動板１６の表面に横溝１５aが多数形成されている。また、前記横溝１５aの間隔が微細過ぎると、数少ない試験により容易に磨耗してしまうため、そのような問題が生じないように所定間隔で多数形成されている。また、前記鉛直移動板１６は、前述のように前記本体枠１４に上下自在に嵌着されるだけでなく、容易に着脱することができるため、前記鉛直移動板１６に多数形成された前記横溝１５aが磨耗してしまった際にも、交換が容易である。   As shown in FIG. 1, the vertical moving plate 16 is fitted to the main body frame 14 so as to freely move up and down, and a large number of the lateral grooves 15 a are formed on the surface. The said vertical movement board 16 comprises the said mounting part 13 with which cross-sectional shape becomes a substantially V shape for mounting the said horizontal stripe 3 which comprises the said test piece 1 with the said description base 17. As shown in FIG. Further, a large number of lateral grooves 15a are formed on the surface of the vertical moving plate 16 so that the transverse stripe 3 placed in the placement portion 13 does not rotate during shear measurement. Further, if the interval between the lateral grooves 15a is too small, it is easily worn by a few tests, so that a large number are formed at a predetermined interval so as not to cause such a problem. Further, the vertical movement plate 16 is not only fitted to the main body frame 14 so as to be freely movable as described above, but also can be easily attached and detached, so that the horizontal grooves formed in the vertical movement plate 16 are formed in large numbers. When 15a is worn out, it can be easily replaced.

さらに、図９に示すように、前記横溝１５aが形成された面と相対する面には、前記本体枠１４を構成する２本の前記柱体１９と、上下自在に嵌着するための凹部２５が、前記鉛直移動板１６の長手方向に形成されている。そうすることで、前記鉛直移動板１６に形成された前記凹部２５が、前記柱体１９に嵌着し、前記横筋３を取外す際には、該横筋３の一部が前記横溝１５aに噛み込んでいることから、該横筋３と共に該鉛直移動板１６が上方へ移動し、該横筋３の取外しを容易に行うことができる。   Furthermore, as shown in FIG. 9, two pillars 19 constituting the main body frame 14 and a recess 25 for fitting up and down freely are provided on a surface opposite to the surface on which the lateral groove 15a is formed. Is formed in the longitudinal direction of the vertical moving plate 16. By doing so, when the said recessed part 25 formed in the said vertical movement board 16 fits in the said pillar 19, and the said horizontal stripe 3 is removed, a part of this horizontal stripe 3 bites into the said horizontal groove 15a. Therefore, the vertical moving plate 16 moves upward together with the transverse bars 3 so that the transverse stripes 3 can be easily removed.

前記載台１７は、前記鉛直移動板１６と向い合って傾斜する傾斜面１７aの表面に横溝１５bが多数形成され、且つ前記本体枠１４に固定されている。前記載台１７は、前記鉛直移動板１６と共に、前記試験片１を構成する前記横筋３を載置するための、断面形状が略V字型となる前記載置部１３を構成している。前記横溝１５bに関しても、前記横溝１５aにおいて上述したように、所定間隔で多数形成されている。さらに、前記載台１７には図１０に示すように、前記本体枠１４に螺接するためのボルト穴２６が設けられている。さらに、前記載台１７は、前記鉛直移動板１６に形成された前記横溝１５aと、前記載台１７に形成された前記横溝１５bと、が対向するように前記本体枠１４に固定される。その際には、図１に示すように、前記載台１７の前記横溝１５bと対向する鉛直面２７が、前記係止片２３と当接するように配設される。さらに、前記載台１７を本体枠１４に固定する際には、図２に示すように、ボルト２８により、前記底板２１に設けられた前記ボルト穴２４を貫通し、前記載台１７に設けられた前記ボルト穴２６を用いて螺接し、固定される。   The table 17 has a large number of lateral grooves 15 b formed on the surface of an inclined surface 17 a that is inclined to face the vertical moving plate 16, and is fixed to the main body frame 14. The above-described table 17 and the vertical movement plate 16 constitute the above-described placement portion 13 having a substantially V-shaped cross-section for placing the transverse muscle 3 constituting the test piece 1. As described above, a large number of the lateral grooves 15b are formed at predetermined intervals in the lateral grooves 15a. Further, as shown in FIG. 10, the above-described table 17 is provided with a bolt hole 26 for screwing into the main body frame 14. Further, the table 17 is fixed to the main body frame 14 so that the lateral groove 15a formed in the vertical movement plate 16 and the lateral groove 15b formed in the table 17 face each other. At that time, as shown in FIG. 1, the vertical surface 27 facing the lateral groove 15 b of the table 17 is disposed so as to contact the locking piece 23. Further, when fixing the above-described table 17 to the main body frame 14, as shown in FIG. 2, the bolt 28 penetrates the bolt hole 24 provided in the bottom plate 21 and is provided in the table 17 described above. Further, the bolt hole 26 is screwed and fixed.

図１０に示すように、前記傾斜面１７aが水平面となす角度αが大きすぎると、異なる太さの横筋への適応性が損なわれる。また、前記角度αが小さすぎると、せん断試験の際に、前記横筋３の回転に対する抑止力が損なわれる。そのため、前記角度αは、前述のような問題が生じないように、例えば、４０〜７０度、好ましくは約６０度とするのが好ましい。さらに、前記載台１７は、本願実施例のように着脱自在に設けられているほうが、前記横溝１５bが、度重なるせん断試験により磨耗した際に、交換が容易で好ましいが、例えば、前記本体枠１４と一体となっていてもよい。   As shown in FIG. 10, when the angle α between the inclined surface 17a and the horizontal plane is too large, the adaptability to horizontal stripes having different thicknesses is impaired. On the other hand, if the angle α is too small, the deterrence against the rotation of the transverse bars 3 is impaired during the shear test. Therefore, for example, the angle α is preferably 40 to 70 degrees, preferably about 60 degrees so that the above-described problems do not occur. Further, it is preferable that the table 17 is detachably provided as in the embodiment of the present invention, because it is easy to replace when the lateral groove 15b is worn by repeated shear tests. 14 may be integrated.

前記載置部１３は、前記鉛直移動板１６と前記載台１７により構成され、断面形状が略V字型となっている。さらに、前記試験片１を構成する前記横筋３の両側が、断面形状が略V字型である前記載置部１３に載置されるが、その際に、前記試験片１を構成する前記縦筋２が、図２に示すように、前記ジョイント１２の軸２９と同軸上となるように、前記載置部１３に前記試験片１が載置されるように設計されている。そのため、従来のようにクランプ１０で固定するような煩雑な作業が必要とならず、効率的に作業を行うことができる。   The mounting portion 13 is composed of the vertical moving plate 16 and the above-described mounting base 17 and has a substantially V-shaped cross section. Further, both sides of the horizontal stripe 3 constituting the test piece 1 are placed on the placement portion 13 having a substantially V-shaped cross-section. As shown in FIG. 2, the test piece 1 is designed to be placed on the placement portion 13 so that the muscle 2 is coaxial with the shaft 29 of the joint 12. For this reason, the complicated work of fixing with the clamp 10 as in the prior art is not required, and the work can be performed efficiently.

また、前記載置部１３は、前記鉛直移動板１６に設けられた前記横溝１５aと、前記傾斜面１７aに設けられた前記横溝１５bとが対向し、断面形状が略V字型となっているため、図３及び図４に示すように、異なる太さの細横筋３a、太横筋３bに対しても、前記試験片固定具１１の構成を変えることなく使用することができ、作業を効率的に行うことができる。   Further, in the mounting portion 13, the lateral groove 15a provided in the vertical movement plate 16 and the lateral groove 15b provided in the inclined surface 17a face each other, and the cross-sectional shape is substantially V-shaped. Therefore, as shown in FIG. 3 and FIG. 4, it is possible to use the thin horizontal streak 3 a and the thick horizontal streak 3 b of different thicknesses without changing the configuration of the test piece fixture 11, and the work can be efficiently performed. Can be done.

さらに、せん断試験を行う際には、前記ジョイント１２及び前記縦筋２が、せん断測定機Iに接続され、図２に示すように、前記縦筋２に図外の引張り手段によって、鉛直下向きの引張力３０を加えることによって、せん断強さを測定する。その時には、前記縦筋２と略直角に溶接された前記横筋３にも、長手方向に渡って鉛直下向きに引張力３０が作用する。それと同時に、図２に示すように、前記横筋３には矢印３１方向への回転力が生じる。また、断面形状が略V字型の前記載置部１３に、前記横筋３が載置され、前記鉛直移動板１６及び前記載台１７にはそれぞれ横溝１５a及び１５bが形成されている。そのため、せん断試験の際は、前記横筋３に矢印３１方向への回転力が作用するが、該記横筋３には、前述した鉛直下向きの引張力３０が作用し、横溝１５a及び１５bが該横筋３に噛み込むため、該横筋３は回転することがない。そのことにより、より正確なせん断強さを測定することができる。   Further, when the shear test is performed, the joint 12 and the longitudinal bar 2 are connected to the shear measuring device I, and as shown in FIG. The shear strength is measured by applying a tensile force of 30. At that time, a tensile force 30 acts on the transverse bars 3 welded substantially perpendicular to the longitudinal bars 2 in the vertically downward direction over the longitudinal direction. At the same time, as shown in FIG. 2, a rotational force in the direction of arrow 31 is generated in the transverse stripe 3. Further, the horizontal stripe 3 is placed on the mounting portion 13 having a substantially V-shaped cross section, and horizontal grooves 15a and 15b are formed in the vertical moving plate 16 and the above-mentioned mounting base 17, respectively. Therefore, during the shear test, a rotational force in the direction of the arrow 31 acts on the transverse muscle 3, but the above-described vertical downward tensile force 30 acts on the transverse muscle 3, and the transverse grooves 15 a and 15 b form the transverse muscle. 3, the transverse stripe 3 does not rotate. Thereby, more accurate shear strength can be measured.

ところで、せん断試験終了後には、前記横筋３を取外す。しかし、上述のように、前記横筋３が前記横溝１５a及び１５bに噛み込むため、該横筋３が外れにくくなる恐れがある。しかし、前記載置部１３を構成する前記鉛直移動板１６が上下自在に嵌着されている。そのため、せん断試験終了時に、前記横筋３を取外す際には、該横筋３の一端部を上方に持上げる。そうすると同時に、図６に示すように、前記横筋３の一部が前記横溝１５aに噛み込んでいることから、前記鉛直移動板１６が前記柱体１９に沿って上方に移動するため、容易に前記横筋３を取外すことができる。また、前述のようにしても前記横筋３を取外すことができないときには、木槌、ハンマー等で前記横筋３の一端を下方から上方に向けて軽く叩くようにすれば、さらに容易に該横筋３を取外すことができる。   By the way, after the end of the shear test, the transverse stripe 3 is removed. However, as described above, since the horizontal stripe 3 bites into the horizontal grooves 15a and 15b, the horizontal stripe 3 may not easily come off. However, the said vertical movement board 16 which comprises the mounting part 13 mentioned above is fitted by the up-and-down direction freely. Therefore, when removing the transverse bar 3 at the end of the shear test, one end of the horizontal bar 3 is lifted upward. At the same time, as shown in FIG. 6, since a part of the horizontal stripe 3 is engaged with the horizontal groove 15a, the vertical movement plate 16 moves upward along the column body 19, so that the The transverse muscle 3 can be removed.
