When fastening and fixing the crossing part of the reinforcing bar, the first pressing piece that contacts the first reinforcing bar remains, and one end edge is bent downward at approximately 90 °, and the tip of the reinforcing bar contacts the second reinforcing bar. A second pressing piece that contacts and a locking piece that is bent with the other edge facing downward are formed, and the first pressing piece is engaged with the second rebar at a position closer to the second pressing piece. With the configuration in which the first bolt insertion hole into which both male screw portions of the U bolt are inserted is formed, the second bolt insertion hole of the fastening plate in which the first pressing piece is brought into contact with the first reinforcing bar is second. Insert both male threaded parts of U-bolts attached to the rebar, and screw nuts into both male threaded parts. The lower end portion of the second pressing piece comes into contact with the second reinforcing bar, and when the nut is further screwed in from this state, the fastening plate is moved with the lower end portion of the second pressing piece coming into contact with the second reinforcing bar as a fulcrum. By rotating in the protruding direction of the locking piece, the first rebar is strongly pressed against the second rebar by the first pressing piece, thereby firmly fastening and fixing the intersection of the first rebar and the second rebar. can do.

また、前記第1押圧片の両第1ボルト挿通孔相互間を結ぶ線と交差する線上に第1鉄筋と第2鉄筋を平行状態で締結固定する際に該第1鉄筋及び第2鉄筋に係合させたUボルトの両雄ねじ部を挿通可能な第2ボルト挿通孔が形成されている構成としたことで、平行状態にある第1鉄筋及び第2鉄筋に該第2鉄筋側から係合させたUボルトの両雄ねじ部を締結プレートにおける第1押圧片の第2ボルト挿通孔に挿通させ、該両雄ねじ部にそれぞれナットをねじ込んで行くことにより、締結プレートにおける第1押圧片が第1鉄筋に当接し、この状態からナットをさらにねじ込んで行くと、第1鉄筋と第2鉄筋がUボルトと第1押圧片との間に強く挟持され、これにより、第1鉄筋と第2鉄筋を平行状態で強固に締結固定することができる。   Further, when the first reinforcing bar and the second reinforcing bar are fastened and fixed in a parallel state on a line intersecting the line connecting the first bolt insertion holes of the first pressing piece, the first reinforcing bar and the second reinforcing bar are engaged with each other. Since the second bolt insertion hole into which both male screw portions of the combined U-bolts can be inserted is formed, the first and second rebars in parallel are engaged from the second rebar side. The both male screw portions of the U-bolt are inserted into the second bolt insertion holes of the first pressing piece in the fastening plate, and nuts are screwed into the male screw portions so that the first pressing piece in the fastening plate becomes the first rebar. When the nut is further screwed in from this state, the first rebar and the second rebar are strongly sandwiched between the U-bolt and the first pressing piece, whereby the first rebar and the second rebar are parallel. It can be firmly fixed in a state.

従って、一種類の高負荷用鉄筋締結具のみで、第1鉄筋と第2鉄筋の交差部の締結固定だけでなく、第1鉄筋と第2鉄筋を互いに平行状態で締結固定することができるようになり、これにより、コストダウンと作業性の向上が可能になるという効果が得られる。   Therefore, it is possible to fasten and fix the first reinforcing bar and the second reinforcing bar in parallel with each other with only one type of high-load reinforcing bar fastener, in addition to fastening and fixing the intersection of the first reinforcing bar and the second reinforcing bar. As a result, it is possible to reduce the cost and improve the workability.

そして、1本のUボルト及びナットと締結プレートのみで構成されるため、従来例2に比べ、部品点数の削減によるコストダウンが可能であると共に、部品点数が少ないため鉄筋交差部への取り付けが容易であり、かつ、2個のナットの螺合・締結作業ですむため、作業性を向上させることができるようになるという効果が得られる。   And since it is composed of only one U-bolt, nut and fastening plate, the cost can be reduced by reducing the number of parts compared to the conventional example 2, and since the number of parts is small, it can be attached to the reinforcing bar intersection. Since it is easy and only two nuts are screwed and fastened, the workability can be improved.

請求項2記載の高負荷用鉄筋締結具では、上述のように、前記第1押圧片には一対の第2ボルト挿通孔のうち係止片側の第2ボルト挿通孔に変えてUボルトの一方の雄ねじ部を挿通可能な側方位置に少なくとも一つの第3ボルト挿通孔が形成されている構成としたことで、平行状態にある直径の細い第1鉄筋と第2鉄筋を締結固定する場合に、第1鉄筋及び第2鉄筋に対し第2鉄筋側から係合させたUボルトの一方の雄ねじ部を第2押圧片寄り側の第2ボルト挿通孔に挿通させ、もう一方の雄ねじ部を第3ボルト挿通孔に挿通させることにより、第2ボルト挿通孔と第3ボルト挿通孔相互間を結ぶ線が両第2ボルト挿通孔相互間を結ぶ線に対し所定角度傾斜した状態になるため、直径の細い第1鉄筋及び第2鉄筋を締結固定させる場合でも、Uボルトにおける両雄ねじ部との間に大きな隙間が生じることなしに第1鉄筋及び第2鉄筋を平行状態で安定よく締結固定させることができるようになる。   In the high load rebar fastener according to claim 2, as described above, one of the U bolts is replaced with the second bolt insertion hole on the locking piece side of the pair of second bolt insertion holes in the first pressing piece. When at least one third bolt insertion hole is formed at a side position through which the male thread portion of the first screw can be inserted, the first rebar and the second rebar with a small diameter in a parallel state are fastened and fixed. The one male threaded portion of the U-bolt engaged with the first reinforcing bar and the second reinforcing bar from the second reinforcing bar side is inserted into the second bolt insertion hole closer to the second pressing piece, and the other male threaded portion is Since the line connecting the second bolt insertion hole and the third bolt insertion hole is inclined by a predetermined angle with respect to the line connecting the two bolt insertion holes by inserting the three bolt insertion holes, the diameter Even when tightening and fixing the first and second reinforcing bars Made without large gap occurs as the first reinforcing bar and the second reinforcing bar can be stabilized well fastened in a parallel state between the two external thread portion in the bolt.

請求項3記載の高負荷用鉄筋締結具では、上述のように、前記係止片が第1鉄筋の外面に略沿った円弧状に形成されている構成としたことで、第1鉄筋に対する当接面積が拡大し、これにより、固定状態での安定性を高めることができるようになる。   In the high load reinforcing bar fastener according to claim 3, as described above, the locking piece is formed in an arc shape substantially along the outer surface of the first reinforcing bar. The contact area is increased, and thus the stability in a fixed state can be increased.

請求項4記載の高負荷用鉄筋締結具では、上述のように、前記ボルト挿通孔が係止片方向へ向けて伸びる長孔に形成されている構成としたことで、第1鉄筋の長孔に沿ってUボルトを移動させることにより、第1鉄筋の直径が変わってもUボルトと係止片との間に第1鉄筋を挟んだ状態で鉄筋交差部を締結固定することができるため、固定状態での安定性をさらに高めることができると共に、直径の異なる複数種類の鉄筋の固定が可能であるため、コストダウンが可能になる。   In the high load reinforcing bar fastener according to claim 4, as described above, the bolt insertion hole is formed as a long hole extending toward the locking piece, so that the long hole of the first reinforcing bar is formed. Since the U-bolt is moved along the first reinforcing bar, even if the diameter of the first reinforcing bar changes, it is possible to fasten and fix the reinforcing bar intersection with the first reinforcing bar sandwiched between the U-bolt and the locking piece. The stability in the fixed state can be further increased, and a plurality of types of reinforcing bars having different diameters can be fixed, so that the cost can be reduced.

請求項5記載の高負荷用鉄筋締結具では、上述のように、前記第1鉄筋と第2鉄筋の交差部を締結固定する際に、第2押圧片の下端中央部に第2鉄筋が係合する係合用凹部が形成されている構成としたことで、第2鉄筋に第2押圧片の係合用凹部が係合する一方、第1鉄筋に係止片が係合する結果、鉄筋交差部の交差角度を維持させることができるようになる。   In the high load reinforcing bar fastener according to claim 5, as described above, when the intersection of the first reinforcing bar and the second reinforcing bar is fastened and fixed, the second reinforcing bar is engaged with the lower end central part of the second pressing piece. As a result of the engagement recess being formed, the engagement recess of the second pressing piece engages with the second rebar, while the engagement piece engages with the first rebar. The crossing angle can be maintained.

請求項6記載の高負荷用鉄筋締結具では、上述のように、前記係合用凹部はその両端部が第2鉄筋に当接するようにその開口幅及び深さが設定されている構成としたことで、鉄筋交差部の交差角度を確実に維持させることができるようになると共に、第2鉄筋の直径が大きくなる程係合用凹部内への食い込み量が少なくなるため、固定する鉄筋の直径が変わることで生じる第1押圧片の傾き量を低減させることができるようになる。   In the high load reinforcing bar fastener according to claim 6, as described above, the opening width and depth of the recess for engagement are set so that both end portions thereof are in contact with the second reinforcing bar. Thus, the crossing angle of the reinforcing bar intersection can be reliably maintained, and the larger the diameter of the second reinforcing bar, the smaller the amount of bite into the recess for engagement, so the diameter of the reinforcing bar to be fixed changes. Thus, the amount of inclination of the first pressing piece can be reduced.

請求項7記載の高負荷用鉄筋締結具では、上述のように、前記両第2ボルト挿通孔の少なくともいずれか一方が両第1ボルト挿通孔相互間を結ぶ線と交差する線に沿って長い長孔に形成されることで、両雄ねじ部相互間の間隔が異なる複数種類のUボルトの使用が可能になるため、第1鉄筋と第2鉄筋を平行状態で締結固定する際に、第1鉄筋と第2鉄筋の直径に適合したUボルトを使用することにより、直径が異なる複数種類の第1鉄筋と第2鉄筋を安定よく平行状態で締結固定させることができるようになる。   In the high load reinforcing bar fastener according to claim 7, as described above, at least one of the second bolt insertion holes is long along a line intersecting a line connecting the first bolt insertion holes. Since it is possible to use a plurality of types of U-bolts having different intervals between the male screw parts by forming the elongated holes, the first rebar and the second rebar are fastened and fixed in a parallel state. By using U-bolts adapted to the diameters of the reinforcing bar and the second reinforcing bar, a plurality of types of first reinforcing bars and second reinforcing bars having different diameters can be fastened and fixed stably in a parallel state.

The first bolt insertion holes 34, 34 are formed as long holes extending toward the locking piece 33 so that the insertion position of the U bolt 1 can be moved.

また、前記第2押圧片32の幅方向中央部が外向き膨らむ膨らみ部35が形成され、該膨らみ部35の下端部には第2鉄筋5が係合する略V字状の係合用凹部35aが形成されている。そして、この係合用凹部35aは、その両端部が第2鉄筋5に当接するようにその開口幅及び深さが設定されている。   Further, a bulging portion 35 in which the center portion in the width direction of the second pressing piece 32 bulges outward is formed, and a substantially V-shaped engagement concave portion 35a with which the second rebar 5 engages at the lower end portion of the bulging portion 35. Is formed. The opening width and depth of the engaging recess 35 a are set so that both end portions thereof are in contact with the second reinforcing bar 5.

また、図6〜9に示すように、前記第1押圧片31の両第1ボルト挿通孔相互間を結ぶ線と交差する線上に、第1鉄筋と第2鉄筋5を平行状態で締結固定する際に該第1鉄筋4及び第2鉄筋5に係合させたUボルト1の両雄ねじ部11、11を挿通可能な第2ボルト挿通孔36が形成されている。そして、第1押圧片31側の第2ボルト挿通孔36は、第1押圧片31の幅方向に長い楕円状に形成されている。   As shown in FIGS. 6 to 9, the first reinforcing bar and the second reinforcing bar 5 are fastened and fixed in a parallel state on a line intersecting the line connecting the first bolt insertion holes of the first pressing piece 31.

A burring portion 37a is formed to extend the opening of 37.

次に、実施例の作用・効果を説明する。   Next, functions and effects of the embodiment will be described.

まず、第1鉄筋と第2鉄筋の交差部を強固に締結固定する場合を、図2〜5に基づいて説明する。
この実施例の高負荷用鉄筋締結具では、上述のように構成されるため、第1鉄筋4に第1押圧片31を当接させた締結プレート3の第1ボルト挿通孔34、34に対し、第2鉄筋5に装着させたUボルト1の両雄ねじ部11、11を挿通させ、該両雄ねじ部11、11にそれぞれナット2、2をねじ込んで行くことにより、第2押圧片32における膨らみ部35の下端部に形成された係合用凹部35aの両端部が第2鉄筋5に当接して位置決めされ、この状態からナット2、2をさらにねじ込んで行くと、第2鉄筋5に当接する第2押圧片32における膨らみ部35の下端部を支点として締結プレート3が係止片33の突出方向に向けて回動することで、第1押圧片31によって第1鉄筋4が第2鉄筋5に強く押し付けられ、これにより、第1鉄筋4と第2鉄筋5の交差部を強固に締結固定することができる。
First, the case where the crossing part of a 1st reinforcing bar and a 2nd reinforcing bar is fastened and fixed is demonstrated based on FIGS.
Since the high-load reinforcing bar fastener of this embodiment is configured as described above, the first bolt insertion holes 34 and 34 of the fastening plate 3 in which the first pressing piece 31 is in contact with the first reinforcing bar 4 are used. By inserting the male screw parts 11 and 11 of the U bolt 1 attached to the second rebar 5 and screwing the nuts 2 and 2 into the male screw parts 11 and 11, respectively, the bulge in the second pressing piece 32 is obtained. Both end portions of the engaging recess 35a formed at the lower end of the portion 35 are positioned in contact with the second reinforcing bar 5, and when the nuts 2 and 2 are further screwed from this state, the second end of the engaging recess 35a contacts the second reinforcing bar 5. The first rebar 4 is turned into the second rebar 5 by the first pressing piece 31 by rotating the fastening plate 3 in the protruding direction of the locking piece 33 with the lower end of the bulging part 35 in the 2 pressing piece 32 as a fulcrum. Strongly pressed, so that The intersection of reinforcing bars 4 and the second reinforcing bar 5 can be fastened firmly.

そして、この実施例の高負荷用鉄筋締結具は、上述のように、1本のUボルト1及びナット2、2と締結プレート3のみで構成されるため、部品点数の削減によるコストダウンが可能であると共に、部品点数が少ないため鉄筋交差部への取り付けが容易であり、かつ、2個のナット2、2の螺合・締結作業ですむため、作業性を向上させることができるようになるという効果が得られる。   Since the high load reinforcing bar fastener of this embodiment is composed of only one U-bolt 1 and nuts 2 and 2 and the fastening plate 3 as described above, the cost can be reduced by reducing the number of parts. In addition, since the number of parts is small, it is easy to attach to the crossing part of the reinforcing bars, and it is only necessary to screw and fasten the two nuts 2 and 2, so that the workability can be improved. The effect is obtained.

また、係止片33が第1鉄筋4の外面に略沿った円弧状に形成されている構成としたことで、第1鉄筋4に対する当接面積が拡大し、これにより、固定状態での安定性を高めることができるようになる。   Further, since the locking piece 33 is formed in an arc shape substantially along the outer surface of the first reinforcing bar 4, the contact area with the first reinforcing bar 4 is expanded, thereby stabilizing in a fixed state. It becomes possible to improve the sex.

また、ボルト挿通孔11、11が係止片33方向へ向けて伸びる長孔に形成されている構成としたことで、第1ボルト挿通孔34の長孔に沿ってUボルト1を移動させることにより、第1鉄筋4の直径が、例えば、図4に示すようにD22、D19、D16と変わっても、Uボルト1と係止片33との間に第1鉄筋4を挟んだ状態で鉄筋交差部を締結固定することができるため、固定状態での安定性をさらに高めることができると共に、直径の異なる複数種類の鉄筋の固定が可能であるため、コストダウンが可能になる。   Further, the bolt insertion holes 11 and 11 are formed as long holes extending in the direction of the locking piece 33, so that the U bolt 1 is moved along the long hole of the first bolt insertion hole 34. Thus, even if the diameter of the first reinforcing bar 4 is changed from D22, D19, D16 as shown in FIG. 4, for example, the reinforcing bar is sandwiched between the U-bolt 1 and the locking piece 33. Since the crossing portion can be fastened and fixed, the stability in the fixed state can be further increased, and a plurality of types of reinforcing bars having different diameters can be fixed, so that the cost can be reduced.

また、第2押圧片32における膨らみ部35の下端部に第2鉄筋5が係合する係合用凹部35aが形成されている構成としたことで、第2鉄筋5に第2押圧片32の係合用凹部35が係合する一方、第1鉄筋4に係止片33が係合する結果、鉄筋交差部の交差角度を維持させることができるようになる。   In addition, since the engaging recess 35 a with which the second reinforcing bar 5 is engaged is formed at the lower end of the bulging part 35 in the second pressing piece 32, the second pressing piece 32 is engaged with the second reinforcing bar 5. As a result of the engagement of the joint recess 35 and the engagement of the locking piece 33 with the first reinforcing bar 4, the crossing angle of the reinforcing bar intersection can be maintained.

また、係合用凹部35aはその両端部が第2鉄筋5に当接するようにその開口幅及び深さが設定されている構成としたことで、鉄筋交差部の交差角度を確実に維持させることができるようになると共に、図5に示すように、第2鉄筋5の直径が大きくなる程係合用凹部35a内への食い込み量が少なくなるため、固定する鉄筋の直径が、例えば、図4に示すようにD22、D19、D16と変わることで生じる第1押圧片31の傾き量を低減させることができるようになる。   Further, the engaging recess 35a is configured such that the opening width and depth thereof are set so that both end portions thereof are in contact with the second reinforcing bar 5, so that the crossing angle of the reinforcing bar crossing portion can be reliably maintained. As shown in FIG. 5, as the diameter of the second reinforcing bar 5 increases, the amount of biting into the engaging recess 35a decreases, so that the diameter of the reinforcing bar to be fixed is, for example, as shown in FIG. Thus, the amount of inclination of the first pressing piece 31 generated by changing to D22, D19, and D16 can be reduced.

次に、第1鉄筋4と第2鉄筋5を平行状態で締結固定する場合を図6、7に基づいて説明する。
この実施例の高負荷用鉄筋締結具では、上述のように構成されるため、平行状態にある第1鉄筋4及び第2鉄筋5に該第2鉄筋5側から係合させたUボルト1の両雄ねじ部11、11を締結プレート3における第1押圧片31の第2ボルト挿通孔36、36に挿通させ、該両雄ねじ部11、11にそれぞれナット2、2をねじ込んで行くことにより、締結プレート3における第1押圧片31が第1鉄筋4に当接し、この状態からナット2、2をさらにねじ込んで行くと、第1鉄筋4と第2鉄筋5がUボルト1と第1押圧片31との間に強く挟持され、これにより、第1鉄筋4と第2鉄筋5を平行状態で強固に締結固定することができる。
Next, a case where the first reinforcing bar 4 and the second reinforcing bar 5 are fastened and fixed in a parallel state will be described with reference to FIGS.
Since the high-load reinforcing bar fastener of this embodiment is configured as described above, the U-bolt 1 engaged with the first reinforcing bar 4 and the second reinforcing bar 5 in the parallel state from the second reinforcing bar 5 side. The male screw parts 11 and 11 are inserted into the second bolt insertion holes 36 and 36 of the first pressing piece 31 in the fastening plate 3, and the nuts 2 and 2 are screwed into the male screw parts 11 and 11, respectively. When the first pressing piece 31 on the plate 3 abuts on the first reinforcing bar 4 and the nuts 2 and 2 are further screwed from this state, the first reinforcing bar 4 and the second reinforcing bar 5 become the U-bolt 1 and the first pressing piece 31. Thus, the first reinforcing bar 4 and the second reinforcing bar 5 can be firmly fastened and fixed in a parallel state.

次に、上記図6、7に示す場合より直径の細い第1鉄筋4と第2鉄筋5を平行状態で締結固定する場合を図8、9に基づいて説明する。
この実施例では、上述のように、前記第1押圧片31には、一対の第2ボルト挿通孔36、36のうち係止片33側の第2ボルト挿通孔36に変えてUボルト1の一方の雄ねじ部11を挿通可能な第3ボルト挿通孔37、37が第1押圧片31の幅方向両端側寄りの位置にそれぞれ形成されているため、平行状態にある直径の細い第1鉄筋4と第2鉄筋5を締結固定する場合でも、上記と同一サイズのUボルト1を用い、第1鉄筋4及び第2鉄筋5に対し第2鉄筋5側から係合させた該Uボルト1の一方の雄ねじ部11を第2押圧片32寄り側の第2ボルト挿通孔36に挿通させ、もう一方の雄ねじ部11を第3ボルト挿通孔37、37のいずれか一方に挿通させることにより、第2ボルト挿通孔36と第3ボルト挿通孔37相互間を結ぶ線が両第2ボルト挿通孔36、36相互間を結ぶ線に対し所定角度傾斜した状態になるため、直径の細い第1鉄筋4及び第2鉄筋5を締結固定させる場合でも、Uボルト1における両雄ねじ部11、11との間に大きな隙間が生じることなしに第1鉄筋4及び第2鉄筋5を平行状態で安定よく締結固定させることができるようになる。
Next, the case where the first rebar 4 and the second rebar 5 having a smaller diameter than those shown in FIGS. 6 and 7 are fastened and fixed in a parallel state will be described with reference to FIGS.
In this embodiment, as described above, the first pressing piece 31 is replaced with the second bolt insertion hole 36 on the locking piece 33 side of the pair of second bolt insertion holes 36, 36. Since the third bolt insertion holes 37, 37 through which one male screw portion 11 can be inserted are formed at positions closer to both ends in the width direction of the first pressing piece 31, the first rebar 4 having a thin diameter in a parallel state. One of the U bolts 1 engaged with the first reinforcing bar 4 and the second reinforcing bar 5 from the second reinforcing bar 5 side using the U bolt 1 having the same size as the above even when the second reinforcing bar 5 is fastened and fixed. By inserting the male screw portion 11 into the second bolt insertion hole 36 on the side closer to the second pressing piece 32 and inserting the other male screw portion 11 into one of the third bolt insertion holes 37 and 37, the second A line connecting between the bolt insertion hole 36 and the third bolt insertion hole 37 Since both the second bolt insertion holes 36 and 36 are inclined at a predetermined angle with respect to the line connecting the two, the male screws in the U-bolt 1 are used even when the first and second reinforcing bars 4 and 5 having a small diameter are fastened and fixed. The first rebar 4 and the second rebar 5 can be stably fastened and fixed in a parallel state without causing a large gap between the portions 11 and 11.

以上詳細に説明してきたように、この実施例の高負荷用鉄筋締結具によれば、一種類の高負荷用鉄筋締結具のみで、第1鉄筋4と第2鉄筋5の交差部の締結固定だけでなく、第1鉄筋4と第2鉄筋5を互いに平行状態で締結固定することができるようになり、これにより、コストダウンと作業性の向上が可能になるという効果が得られる。   As described above in detail, according to the high load reinforcing bar fastener of this embodiment, only one type of high load reinforcing bar fastener is used to fasten and fix the intersection of the first reinforcing bar 4 and the second reinforcing bar 5. In addition, the first reinforcing bar 4 and the second reinforcing bar 5 can be fastened and fixed in parallel with each other, thereby obtaining the effects of being able to reduce costs and improve workability.

また、実施例では、第2押圧片32における膨らみ部35の下端部に第2鉄筋5が係合する係合用凹部35aが形成されている構成としたが、必ずしも必要ではない。   In the embodiment, the engaging recess 35a with which the second reinforcing bar 5 is engaged is formed at the lower end of the bulging portion 35 of the second pressing piece 32, but this is not always necessary.

また、前記両第2ボルト挿通孔36、36の少なくともいずれか一方が両第1ボルト挿通孔34、34相互間を結ぶ線と交差する線に沿って長い長孔に形成すれば、両雄ねじ部11、11相互間の間隔が異なる複数種類のUボルト1の使用が可能になるため、第1鉄筋4と第2鉄筋5を平行状態で締結固定する際に、第1鉄筋4と第2鉄筋5の直径に適合したUボルト1を使用することにより、直径が異なる複数種類の第1鉄筋4と第2鉄筋を5安定よく平行状態で締結固定させることができるようになる。   If at least one of the second bolt insertion holes 36, 36 is formed as a long long hole along a line intersecting the line connecting the first bolt insertion holes 34, 34, both male screw portions Since the use of a plurality of types of U-bolts 1 having different distances from each other is possible, when the first reinforcing bar 4 and the second reinforcing bar 5 are fastened and fixed in a parallel state, the first reinforcing bar 4 and the second reinforcing bar By using the U-bolt 1 adapted to the diameter of 5, a plurality of types of first reinforcing bars 4 and second reinforcing bars having different diameters can be fastened and fixed in a stable state in a stable manner.
