The upper plate portion 161 is provided with a number of long groove-like drain holes 163 extending in the width direction at intervals.

足場板用固定金具１００は、足場板１６０の上側に配置される上ホールド部材１０１と、足場板１６０の下側に配置され上ホールド部材１０１と協働してＨ形鋼１５０及び足場板１６０を挟持する下ホールド部材１０２と、上ホールド部材１０１と下ホールド部材１０２とを互いに引き付けるためのネジ１０３とを有している。   The scaffolding plate fixing bracket 100 includes an upper holding member 101 disposed on the upper side of the scaffolding plate 160 and an H-shaped steel 150 and the scaffolding plate 160 disposed in cooperation with the upper holding member 101 disposed on the lower side of the scaffolding plate 160. It has a lower hold member 102 for clamping, and a screw 103 for attracting the upper hold member 101 and the lower hold member 102 to each other.

上ホールド部材１０１は、足場板１６０の水抜き孔１６３に挿入される凹状部１１１と、この凹状部１１１の両側に設けられ足場板１６０上に配置される上板部１１２と、上板部１１２の端縁に設けられ足場板１６０の水抜き孔１６３に挿入される脚部１１３とを有している。凹状部１１１には、ボルト孔１１４が設けられている。   The upper hold member 101 includes a concave portion 111 inserted into the drain hole 163 of the scaffold plate 160, an upper plate portion 112 provided on both sides of the concave portion 111 and disposed on the scaffold plate 160, and the upper plate portion 112. And a leg portion 113 that is inserted into the drain hole 163 of the scaffold plate 160. The concave portion 111 is provided with a bolt hole 114.

下ホールド部材１０２は、縦辺部１２１と横辺部１２２とによって略Ｌ字状に形成されている。横辺部１２２には、ネジ１０３を螺入するネジ孔１２３が設けられている。また、下ホールド部材１０２の縦辺部１２１及び横辺部１２２は、図１１に示すように、その横断面が略コの字状に形成されている。   The lower hold member 102 is formed in a substantially L shape by a vertical side portion 121 and a horizontal side portion 122. The lateral side portion 122 is provided with a screw hole 123 into which the screw 103 is screwed. Further, as shown in FIG. 11, the vertical side portion 121 and the horizontal side portion 122 of the lower hold member 102 have a substantially U-shaped cross section.

図１０に示すように、足場板用固定金具１００によって足場板１６０をＨ形鋼１５０に固定する場合は、上ホールド部材１０１を足場板１６０上に載置し、凹状部１１１及び脚部１１３をそれぞれ異なる水抜き孔１６３に挿入する。また、下ホールド部材１０２の横辺部１２２をＨ形鋼１５０における上側のフランジ１５１の下側に配置し、縦辺部を足場板１６０の下側に配置する。   As shown in FIG. 10, when the scaffold plate 160 is fixed to the H-shaped steel 150 by the scaffold plate fixing bracket 100, the upper hold member 101 is placed on the scaffold plate 160, and the concave portion 111 and the leg portion 113 are attached. Each is inserted into a different drainage hole 163. Further, the lateral side portion 122 of the lower hold member 102 is disposed below the upper flange 151 in the H-shaped steel 150, and the longitudinal side portion is disposed below the scaffold plate 160.

そして、ネジ１０３の軸部１３１を上ホールド部材１０１の上側から凹状部１１１のボルト孔１１４、及び足場板１６０の水抜き孔１６３を介して足場板１６０の下側に通し、軸部１３１の先端のネジ部分１３２を下ホールド部材１０２のネジ孔１２３に螺入してネジ１０３を締め付ける。これにより、上ホールド部材１０１と下ホールド部材１０２とが互いに引き付けられて、上ホールド部材１０１と、下ホールド部材１０２の横辺部１２２とによって足場板１６０とＨ形鋼１５０とが重ねられた状態で挟持され、足場板１６０がＨ形鋼１５０に固定される。   Then, the shaft portion 131 of the screw 103 is passed from the upper side of the upper holding member 101 to the lower side of the scaffold plate 160 through the bolt hole 114 of the concave portion 111 and the drain hole 163 of the scaffold plate 160, and the tip of the shaft portion 131. The screw portion 132 is screwed into the screw hole 123 of the lower hold member 102 and the screw 103 is tightened. Thereby, the upper hold member 101 and the lower hold member 102 are attracted to each other, and the scaffold plate 160 and the H-shaped steel 150 are overlapped by the upper hold member 101 and the lateral side portion 122 of the lower hold member 102.

しかしながら、従来の特許文献１に記載の足場板用固定金具１００は、図１２に示すように、何らかの原因で足場板用固定金具１００のＨ形鋼１５０に対する取付姿勢が初期取付姿勢から変化した場合、下ホールド部材１０２の直線状の横辺部１２２がＨ形鋼１５０のフランジ１５１に対して交差する方向に傾斜して、凹辺部１２２及びフランジ１５１間の接触長さが減少し、足場板１６０のＨ形鋼１５０に対する固定力が減少するおそれがあった。なお、図１２は、下ホールド部材１０２が図１０中の時計回転方向に傾斜した場合を示しているが、下ホールド部材１０２が図１０中の反時計回転方向に傾斜した場合も、横辺部１２２とフランジ１５１との接触長さが減少する。   However, as shown in FIG. 12, the scaffolding plate fixing bracket 100 described in the conventional patent document 1 has a case where the mounting posture of the scaffolding plate fixing bracket 100 with respect to the H-section steel 150 is changed from the initial mounting posture for some reason. In addition, the linear lateral side portion 122 of the lower holding member 102 is inclined in a direction intersecting the flange 151 of the H-shaped steel 150, and the contact length between the concave side portion 122 and the flange 151 is reduced, and the scaffold plate There was a possibility that the fixing force to the H-shaped steel 150 of 160 would decrease. FIG. 12 shows the case where the lower hold member 102 is inclined in the clockwise direction in FIG. 10, but the horizontal side portion is also shown when the lower hold member 102 is inclined in the counterclockwise direction in FIG. 10. The contact length between 122 and the flange 151 is reduced.

本発明は、かかる従来の問題点を解決するためになされたもので、被固定部材に対する取付姿勢が変化した場合でも、足場板の被固定部材に対する固定力が減少するのを抑制できる足場板固定用金具を提供することを目的とする。   The present invention was made to solve such a conventional problem, and even when the mounting posture with respect to the member to be fixed is changed, the scaffold plate fixing that can suppress the reduction of the fixing force of the scaffold plate to the member to be fixed is provided. The purpose is to provide metal fittings.

本発明は、前記課題を解決するため、以下の手段を採用した。
すなわち、本発明の足場板固定用金具は、被固定部材上に載置された足場板の上側に配置される上ホールド部材と、前記足場板の下側に配置され、前記上ホールド部材と協働して前記被固定部材及び前記足場板を挟持する下ホールド部材と、前記上ホールド部材と前記下ホールド部材とを互いに引き付ける引き付け部材と、を備え、前記下ホールド部材は、前記足場板の下面に接触する第１の接触部と、前記被固定部材の下面に対して交差する方向に延伸し、且つ先端部のみ前記被固定部材の前記下面に接触する第２の接触部と、前記第１の接触部と前記第２の接触部とを連結する連結部と、を有し、かつその横断面がＵ字状に湾曲していることを特徴とする。 The present invention employs the following means in order to solve the above problems.
In other words, the scaffolding plate fixing bracket of the present invention is arranged on the upper side of the scaffolding plate placed on the member to be fixed, on the lower side of the scaffolding plate, and cooperates with the upper holding member. A lower hold member that operates to clamp the fixed member and the scaffold plate, and an attracting member that attracts the upper hold member and the lower hold member to each other, and the lower hold member is a lower surface of the scaffold plate. A first contact portion that contacts the lower surface of the fixed member; a second contact portion that extends in a direction intersecting the lower surface of the fixed member; the contact portion and the connecting portion connecting the second contact portion, have a, and its cross-section is characterized in that it is curved in U-shape.

被固定部材としては、ビル等の構成部材、例えばＨ形鋼などを例示できる。本発明によれば、下ホールド部材の第２接触部が被固定部材に対して交差する方向に延伸し、且つ先端部のみ被固定部材の下面に接触するので、足場板の被固定部材に対する取付姿勢が初期取付姿勢から変化しても、第２接触部の先端部のみ被固定部材の下面に接触するという接触状態は変化しない。従って、上ホールド部材と下ホールド部材による足場板及び被固定部材の挟持力が変化しないので、足場板の被固定部材に対する固定力が減少するのを抑制できる。   Examples of the member to be fixed include structural members such as buildings, such as H-shaped steel. According to the present invention, the second contact portion of the lower hold member extends in a direction intersecting the fixed member, and only the tip portion contacts the lower surface of the fixed member. Even if the posture changes from the initial mounting posture, the contact state in which only the tip portion of the second contact portion contacts the lower surface of the fixed member does not change. Therefore, since the clamping force of the scaffold plate and the fixed member by the upper hold member and the lower hold member does not change, it is possible to suppress a decrease in the fixing force of the scaffold plate to the fixed member.

ここで、前記第２の接触部には、前記被固定部材に対する滑りを抑制する滑り抑制手段が設けられている構成にできる。滑り抑制手段としては、剣先状の多数の凹凸を例示できる。この構成によれば、足場板固定用金具の被固定部材に対する取付姿勢が初期取付姿勢から変化したときに、第２接触部が被固定部材に対して滑るのを抑制して、第２接触部が被固定部材から外れるのを抑制できる。これにより、足場板を被固定部材に確実に固定できる。   Here, the second contact portion may be provided with a slip suppression means that suppresses slipping with respect to the fixed member. Examples of the slip suppression means include a number of sword-shaped irregularities. According to this configuration, the second contact portion is prevented from sliding with respect to the fixed member when the attachment posture of the scaffolding plate fixing bracket to the fixed member is changed from the initial mounting posture. Can be prevented from coming off from the fixed member. Thereby, a scaffold board can be fixed to a member to be fixed reliably.

また、前記下ホールド部材は、その横断面が略Ｕ字状に湾曲している構成にできる。この構成によれば、下ホールド部材の横断面に応力が集中する角部がないので、従来のように下ホールド部材の横断面がコの字状で角部がある場合に比べて強度を高くできる。   Further, the lower hold member can be configured such that its transverse section is curved in a substantially U shape. According to this configuration, since there is no corner portion where stress concentrates on the cross section of the lower hold member, the strength is higher than in the conventional case where the cross section of the lower hold member is U-shaped and has a corner portion. it can.

本発明によれば、足場板固定用金具の被固定部材に対する取付姿勢が初期取付姿勢から変化した場合でも、足場板の被固定部材に対する固定力が減少するのを抑制できる。   ADVANTAGE OF THE INVENTION According to this invention, it can suppress that the fixing force with respect to the to-be-fixed member of a scaffold board | plate decreases even when the attachment attitude | position with respect to the to-be-fixed member of a bracket fixing metal fixture changes from an initial mounting attitude.

A tip end portion 31 a of the first contact portion 31 of the lower hold member 12 is in contact with a lower surface 61 a of the upper plate portion 61 of the scaffold plate 60.

下ホールド部材１２の第２接触部３２は、足場板６０の下側で且つＨ形鋼５０のフランジ５１の下側に配置されている。そして、第２接触部３２の先端に設けられた凸部３４の鋭角部分が、フランジ５１の下面５１ａに接触している。足場板固定用金具１のネジ１３の頭部４２は、上ホールド部材１１の凹状部２０内に挿入されている。ネジ１３の軸部４０は、上ホールド部材１１の上側から凹状部２０のボルト孔２３を介して足場板６０の下側に通され、軸部４０の先端のネジ部４１が下ホールド部材１２における連結部３３のネジ孔３５に螺入されている。そして、ネジ１３が締め付けられて、上ホールド部材１１と下ホールド部材１２とが互いに強く引き付けられている。   The second contact portion 32 of the lower hold member 12 is disposed below the scaffold plate 60 and below the flange 51 of the H-section steel 50. The acute angle portion of the convex portion 34 provided at the tip of the second contact portion 32 is in contact with the lower surface 51 a of the flange 51. The head portion 42 of the screw 13 of the scaffolding plate fixing bracket 1 is inserted into the concave portion 20 of the upper hold member 11. The shaft portion 40 of the screw 13 is passed from the upper side of the upper hold member 11 to the lower side of the scaffolding plate 60 through the bolt hole 23 of the concave portion 20, and the screw portion 41 at the tip of the shaft portion 40 is in the lower hold member 12. It is screwed into the screw hole 35 of the connecting portion 33. Then, the screw 13 is tightened, and the upper hold member 11 and the lower hold member 12 are strongly attracted to each other.

ここでは、Ｈ形鋼５０及び足場板６０が重ねられた状態で、足場板固定用金具１の上ホールド部材１１と下ホールド部材１２によって挟持され、足場板６０がＨ形鋼５０に確実に固定されている。   Here, in a state where the H-shaped steel 50 and the scaffolding plate 60 are overlapped, the scaffolding plate fixing bracket 1 is clamped by the upper hold member 11 and the lower hold member 12, and the scaffolding plate 60 is securely fixed to the H-shaped steel 50. Has been.

このときの足場板固定用金具１の初期取付姿勢では、下ホールド部材１２の第１接触部３１及びネジ１３の軸部４０が、Ｈ形鋼５０のウェブ５２に対して略平行に配置されている。また、下ホールド部材１２の連結部３３は、Ｈ形鋼５０のフランジ５１に対して略平
行に配置されている。 In the initial mounting posture of the scaffolding plate fixing bracket 1 at this time, the first contact portion 31 of the lower hold member 12 and the shaft portion 40 of the screw 13 are disposed substantially parallel to the web 52 of the H-shaped steel 50. Yes. Further, the connecting portion 33 of the lower hold member 12 is disposed substantially parallel to the flange 51 of the H-section steel 50.

図７は、足場板固定用金具１の取付姿勢が初期取付姿勢から変化した状態、ここでは、足場板固定用金具１の取付姿勢が図７中の時計回転方向に傾斜した状態を示す。この場合は、下ホールド部材１２の第１接触部３１がＨ形鋼５０のウェブ５２に対して交差する方向に傾斜し、連結部３３がＨ形鋼５０のフランジ５１に対して交差する方向に傾斜する。   FIG. 7 shows a state in which the mounting posture of the scaffolding plate fixing bracket 1 is changed from the initial mounting posture, and here, a state in which the mounting posture of the scaffolding plate fixing bracket 1 is inclined in the clockwise direction in FIG. In this case, the first contact portion 31 of the lower hold member 12 is inclined in a direction intersecting with the web 52 of the H-section steel 50, and the connecting portion 33 is intersected with the flange 51 of the H-section steel 50. Tilt.

しかし、この場合でも、下ホールド部材１２の第２接触部３２は、その先端部の凸部３４のみフランジ５１に接触する状態を維持している。従って、足場板固定用金具１の取付姿勢が変化したとしても、足場板固定用金具１による足場板６０のＨ形鋼５０に対する固定力が減少するのを抑制できる。   However, even in this case, the second contact portion 32 of the lower hold member 12 maintains a state in which only the convex portion 34 at the tip end portion is in contact with the flange 51. Therefore, even if the mounting posture of the scaffolding plate fixing bracket 1 changes, it is possible to suppress a decrease in the fixing force of the scaffolding plate 60 to the H-shaped steel 50 by the scaffolding plate fixing bracket 1.

また、第２接触部３２の凸部３４は先端が鋭角なので、足場板固定用金具１のＨ形鋼５０に対する取付姿勢が変化した場合でも、凸部３４はフランジ５１に対して殆ど滑ることなく元の位置に保持される。従って、第２接触部３２がフランジ５１から外れるのを抑制でき、足場板６０をＨ形鋼５０に確実に固定できる。   Further, since the convex portion 34 of the second contact portion 32 has an acute tip, the convex portion 34 hardly slides against the flange 51 even when the mounting posture of the scaffolding plate fixing bracket 1 with respect to the H-shaped steel 50 is changed. Held in its original position. Therefore, the second contact portion 32 can be prevented from coming off from the flange 51, and the scaffold plate 60 can be reliably fixed to the H-section steel 50.

また、下ホールド部材１２は、第１接触部３１、第２接触部３２及び連結部３３の横断面が略Ｕ字状に形成され、応力が集中する角部がないので、従来のように横断面がコの字状で角部がある場合に比べて、強度を高くできる。また、上ホールド部材１１と下ホールド部材１２とを互いに引き付けるネジ１３は、足場板６０の水抜き孔６３に挿通されるので、足場板６０にネジ１３を挿通させるために特別な孔などを設ける必要がなく、構成を簡略化できる。   In addition, the lower hold member 12 has a substantially U-shaped cross section of the first contact portion 31, the second contact portion 32, and the connecting portion 33, and has no corners where stress is concentrated. The strength can be increased compared to the case where the surface is U-shaped and has corners. Further, since the screw 13 that pulls the upper hold member 11 and the lower hold member 12 together is inserted into the drain hole 63 of the scaffold plate 60, a special hole or the like is provided to allow the screw 13 to be inserted into the scaffold plate 60. There is no need, and the configuration can be simplified.

また、上ホールド部材１１は、凹状部２０の両端部に補強壁２５が立設されているので、凹状部２０の両側から力が作用した場合でも、凹状部２０月ぶれるのを抑制できる。これに対して、図８に示す従来の上ホールド部材１０１は、凹状部１１１の両端部が単なる平板状に形成されているので、凹状部１１１に両側から力が作用した場合、凹状部１１１が潰れるおそれがある。   Further, since the upper hold member 11 is provided with the reinforcing walls 25 at both ends of the concave portion 20, even when force is applied from both sides of the concave portion 20, it is possible to prevent the concave portion 20 from blurring. On the other hand, in the conventional upper hold member 101 shown in FIG. 8, since both ends of the concave portion 111 are formed in a simple flat plate shape, when force is applied to the concave portion 111 from both sides, the concave portion 111 There is a risk of crushing.

なお、図６は、足場固定用金具１の取付姿勢が初期取付姿勢に対して図６中の時計回転方向に傾斜した場合を示したが、足場固定用金具１の取付姿勢が初期取付姿勢に対して図６中の反時計回転方向に傾斜した場合も同様である。   6 shows a case where the mounting posture of the scaffolding fixing bracket 1 is inclined in the clockwise direction in FIG. 6 with respect to the initial mounting posture, but the mounting posture of the scaffolding fixing bracket 1 is in the initial mounting posture. The same applies to the case of tilting counterclockwise in FIG.
