That is, the other end portion of the spring support rod 21 having one end portion penetrated and fixed to the downward projecting piece 11a of the lock fitting 11 is inserted and supported in the rod insertion hole 22 provided in the flange wall portion 10a of the abutment fitting 10, A coil spring 21 is inserted into the rod 21, whereby the lock fitting 11 is urged toward one side of the horizontal plate portion 5 in the length direction (rightward with respect to FIGS. 2A and 2B). Therefore, the lock pin 16 is normally engaged with any one of the lock grooves 14 by the urging force of the coil spring 12 to lock the abutting metal fitting 10 at that position, and locks against the coil spring 12. The metal fitting 11, that is, the lock pin 16 is displaced from the lock groove 14 to the long groove 13 side to release the lock of the contact metal fitting 10, and the lock metal fitting 11 is moved together with the contact metal fitting 10 in the width direction of the horizontal plate portion 5. It can be moved.

上記のように構成される足場板隙間プレート１の使用にあたり、図７に示すように対向する足場用建枠２，２の横材３，２間に架け渡された足場板４の側端部（図７（ａ）の図中下端縁側）に発生する隙間、あるいは図８に示すように足場用建枠２，２の横材３，３間に並列に架け渡された２枚の足場板４，４間に形成される隙間（図８（ａ）の図中中央部側）を塞ぐように足場板隙間プレート１を取り付ける。この足場板隙間プレート１の取付ける際は、上記隙間の上方にプレート本体７を位置させた状態で、側枠部６の両端に突出する係止用フック８，８を両足場用建枠２，２の横材３，３に係止させ、そして水平板部５の先端部５ａを足場板４の側端部上面に載置させる。   In using the scaffold plate gap plate 1 configured as described above, as shown in FIG. 7, the side end portion of the scaffold plate 4 spanned between the cross members 3 and 2 of the opposing building frames 2 and 2 as shown in FIG. (2) (a bottom edge side in the drawing of FIG. 7A), or two scaffold plates laid in parallel between the cross members 3, 3 of the scaffolding frames 2, 2 as shown in FIG. The scaffolding plate gap plate 1 is attached so as to block the gap formed between the four and the four (the center side in FIG. 8A). When the scaffold plate gap plate 1 is attached, the locking hooks 8, 8 protruding from both ends of the side frame portion 6 with the plate body 7 positioned above the gap are attached to both scaffold building frames 2. The horizontal members 3 and 3 are engaged with each other, and the front end portion 5 a of the horizontal plate portion 5 is placed on the upper surface of the side end portion of the scaffold plate 4.

図４〜図６は、図７の使用形態におけるロック手段９の作用を示したもので、図４の(a) 〜(c) は、プレート本体７を隙間塞ぎ位置にロックするロック手段９がロック解除された状態を示す。即ち、隙間塞ぎ位置にあるプレート本体７がロック手段９によるロックを解除された状態では、同図の(a) に示すようにロック金具１１のロックピン１６がプレート本体７の水平板部５に設けられた複数のロック溝１４・・・のうち図中左端のロック溝１４（足場板４の側端部４ａから最も離れたロック溝１４）に係入した状態にあって、当接金具１０の先端部１０ａが同図の(b) に示すように足場板４の側端部４ａから最も離間した位置にあり、このままではプレート本体７はその幅方向にズレるおそれがある。   4 to 6 show the operation of the locking means 9 in the usage form of FIG. 7. FIGS. 4A to 4C show that the locking means 9 that locks the plate body 7 in the gap closing position is shown in FIGS. Indicates unlocked state. That is, when the plate main body 7 in the gap closing position is unlocked by the locking means 9, the lock pin 16 of the lock fitting 11 is attached to the horizontal plate portion 5 of the plate main body 7 as shown in FIG. Among the plurality of provided lock grooves 14..., The contact metal fitting 10 is engaged with the lock groove 14 at the left end in the figure (the lock groove 14 farthest from the side end portion 4 a of the scaffold plate 4). As shown in FIG. 5B, the distal end portion 10a is at the position farthest from the side end portion 4a of the scaffold plate 4, and the plate body 7 may be displaced in the width direction as it is.

従って、プレート本体７をロック手段９により隙間塞ぎ位置にロックする必要がある。そのために、コイルバネ１２の付勢力に抗してロック金具１１を当接金具１０から独立してスライドさせ、ロックピン１６をロック溝１４から長溝１３側に変位させて該ロックピン１６を長溝１３に沿って移動可能となることによって、当接金具１０をプレート本体７の幅方向に移動可能とした状態を図５の(a) 〜(c) に示す。ロックピン１６をロック溝１４から長溝１３側に変位させる時は、ロック金具１１の下向き突片１１ａ側を図４の(c) の矢印で示す方向にバネ１２の付勢力に抗して手で押してやればよく、図５の（ｃ）はロックピン１６を長溝１３側に変位させた状態を示す。そしてこの押したままロック金具１１と共に当接金具１０を図５の（ａ）の図中右方向（足場板４の側端部４ａに近づく方向）、即ち、足場板４の側端部４ａが長溝１３の長手方向中間部に位置する部分まで移動させる。この時、当接金具１０は、そのガイドピン１８が水平板部５のガイド長溝１７に沿って案内され、ロック金具１１は、そのロックピン１６が水平板部５の長溝１３に沿って案内される。そして図５（ｂ）に示すように、当接金具１０の竪壁部１０ａの先端縁１０ａ1が足場板４の側端面４ａに当接した時に、ロック金具１１から手を離すと、コイルバネ１２の付勢力によってロックピン１６が足場板４の側端面４ａに近い中央部のロック溝１４に係入し、当接金具１０をその先端縁１０ａ1が足場板４の側端面４ａに当接した状態にロックし、これによってプレート本体７が隙間塞ぎ位置にロックされる。この例は、足場板４の側端面４ａ側の隙間が比較的に狭い場合の位置でフレート本体７をロックする状態を示すものである。 Therefore, it is necessary to lock the plate body 7 at the gap closing position by the locking means 9. For this purpose, the lock fitting 11 is slid independently of the abutment fitting 10 against the urging force of the coil spring 12, and the lock pin 16 is displaced from the lock groove 14 toward the long groove 13 so that the lock pin 16 is moved into the long groove 13. FIGS. 5A to 5C show a state in which the contact fitting 10 can be moved in the width direction of the plate body 7 by being movable along the direction. When the lock pin 16 is displaced from the lock groove 14 to the long groove 13 side, the downward protruding piece 11a side of the lock fitting 11 is moved by hand against the biasing force of the spring 12 in the direction indicated by the arrow in FIG. FIG. 5C shows a state in which the lock pin 16 is displaced toward the long groove 13 side. Then, with the lock metal 11 being pressed, the abutment metal 10 is moved to the right in FIG. 5A (in the direction approaching the side edge 4a of the scaffold plate 4), that is, the side edge 4a of the scaffold plate 4 is It moves to the part located in the longitudinal direction intermediate part of the long groove 13. At this time, the guide pin 18 of the abutment fitting 10 is guided along the guide long groove 17 of the horizontal plate portion 5, and the lock pin 11 of the contact fitting 10 is guided along the long groove 13 of the horizontal plate portion 5. The Then, as shown in FIG. 5B, when the tip edge 10a 1 of the collar wall portion 10a of the abutment fitting 10 abuts against the side end surface 4a of the scaffold plate 4, when the hand is released from the lock fitting 11, the coil spring 12 The urging force causes the lock pin 16 to engage with the lock groove 14 at the center near the side end surface 4 a of the scaffold plate 4, and the tip edge 10 a 1 of the contact fitting 10 contacts the side end surface 4 a of the scaffold plate 4. The plate body 7 is locked in the gap closing position. This example shows a state where the fret body 7 is locked at a position where the gap on the side end face 4a side of the scaffold plate 4 is relatively narrow.

図６の（ａ）〜（ｃ）は、足場板４の側端部４ａ側の隙間が尤も大きい場合のロック状態を示すもので、上記のように当接金具１０をロック金具１１と共に、図６の（ａ）の図中右方向（足場板４の側端部４ａに近づく方向）、即ち、足場板４の側端部４ａが長溝１３の長手方向終端部の位置まで移動させる。そして図６（ｂ）に示すように、当接金具１０の竪壁部１０ａの先端縁１０ａ1が足場板４の側端面４ａに当接した時に、ロック金具１１から手を離すと、図６の（ｃ）に矢印で示すように、コイルバネ１２の付勢力によってロックピン１６が足場板４の側端面４ａに最も近いロック溝１４に係入し、当接金具１０をその先端縁１０ａ1が足場板４の側端面４ａに当接した状態にロックし、これによってプレート本体７が隙間塞ぎ位置にロックされる。 FIGS. 6A to 6C show a locked state when the gap on the side end portion 4a side of the scaffold plate 4 is extremely large. The contact metal fitting 10 together with the lock metal fitting 11 as described above is shown in FIG. 6 (a) in the right direction (the direction approaching the side end 4a of the scaffold plate 4), that is, the side end 4a of the scaffold plate 4 is moved to the position of the longitudinal end of the long groove 13. Then, as shown in FIG. 6B, when the tip edge 10a 1 of the heel wall portion 10a of the abutment fitting 10 abuts on the side end surface 4a of the scaffold plate 4, the hand is released from the lock fitting 11 and FIG. As shown by an arrow in (c), the lock pin 16 is engaged with the lock groove 14 closest to the side end face 4a of the scaffold plate 4 by the urging force of the coil spring 12, and the abutting metal fitting 10 has its tip edge 10a 1 It locks in the state contact | abutted to the side end surface 4a of the scaffold board 4, and, thereby, the plate main body 7 is locked to a gap blockage position.

そして、この時、図５（ｂ）及び図６（ｂ）に示すように、当接金具１０の竪壁部１０ａの先端下部に設けてある係合部１０ａｏが足場板４の側端下面部に係合する状態となるため、この状態で、風圧などによるプレート本体７の浮き上がりが防止されることになる。   At this time, as shown in FIGS. 5 (b) and 6 (b), the engaging portion 10 ao provided at the lower end of the flange wall portion 10 a of the abutment fitting 10 is a lower surface portion of the side end of the scaffold plate 4. In this state, the plate body 7 is prevented from being lifted by wind pressure or the like.

上記のように当接金具１０がロック金具１１によりロックされて、プレート本体７が隙間塞ぎ位置にロックされた状態から、ロックを解除するには、コイルバネ１２の付勢力に抗しロック金具１１を当接金具１０から独立してスライドさせて、ロックピン１６をロック溝１４から長溝１３側に変位させ、そのまま当接金具１０をロック金具１１と共に、足場板４の側端部から離れる方向に移動させればよい。そして、その状態でプレート本体７を持ち上げることにより、足場板隙間プレート１を取り外すことができる。   In order to release the lock from the state in which the contact metal fitting 10 is locked by the lock metal fitting 11 and the plate body 7 is locked at the gap closing position as described above, the lock metal fitting 11 is resisted against the urging force of the coil spring 12. By sliding independently from the abutment metal fitting 10, the lock pin 16 is displaced from the lock groove 14 to the long groove 13 side, and the abutment metal fitting 10 is moved together with the lock metal fitting 11 in a direction away from the side end of the scaffold plate 4. You can do it. And the scaffold board clearance gap plate 1 can be removed by lifting the plate main body 7 in the state.

以上説明したように、足場板隙間プレート１のプレート本体７を隙間塞ぎ位置にロックしたり、ロック解除するのに、従来の足場板隙間プレートのようにボルトを締めたり、緩めたりする面倒が不要で、ロック金具１１を当接金具１０から独立してプレート本体７の長さ方向に変位させると共に、このロック金具１１を当接金具１０と共にプレート本体７の幅方向に一体に移動させるだけでよいから、操作が非常に簡単で容易となり、足場板の側端部側の隙間の大きさに合わせて該側端部端面に当接金具１０が当接ロックするロック位置を自在に調整することができる。   As described above, it is not necessary to take the trouble of tightening or loosening bolts like the conventional scaffold plate gap plate to lock or unlock the plate body 7 of the scaffold plate gap plate 1 at the gap closing position. Thus, it is only necessary to displace the lock fitting 11 in the length direction of the plate body 7 independently of the contact fitting 10 and to move the lock fitting 11 together with the contact fitting 10 in the width direction of the plate body 7. Therefore, the operation is very simple and easy, and the lock position at which the abutment metal fitting 10 abuts and locks to the end surface of the side end can be freely adjusted in accordance with the size of the gap on the side end of the scaffolding plate. it can.
