しかしながら、図13に示す従来の幅木2の配設方法では、係止部材15の板状部材151が第1横材41に、係止部材16の板状部材161が第2横材42にそれぞれ載せ置かれるため、足場の振動等に起因して、幅木2が建枠4から外れるおそれがあった。また、幅木2を建枠4にボルト止め等して固定する方法もあるが、幅木2の取り付けおよび取り外しに手間がかかる。   However, in the conventional arrangement method of the skirting board 2 shown in FIG. 13, the plate-like member 151 of the locking member 15 is the first cross member 41, and the plate-like member 161 of the locking member 16 is the second cross member 42. Since they are respectively placed, there is a possibility that the skirting board 2 may come off from the building frame 4 due to vibration of the scaffold or the like. Although there is a method of fixing the skirting board 2 to the building frame 4 by bolting or the like, it takes time and labor to attach and remove the skirting board 2.

それ故に本発明の目的は、幅木が建枠からの外れることを防止できると共に、幅木の取り付け、取り外しを簡便に行うことの可能な幅木の固定構造および幅木を提供することである。   Therefore, an object of the present invention is to provide a baseboard fixing structure and baseboard that can prevent the baseboard from coming off from the building frame and that can be easily attached and detached. .

本発明は、上記の課題を解決するために、以下の構成を採用した。なお、括弧内の参照符号および補足説明等は、本発明の理解を助けるために後述する実施形態との対応関係の一例を示したものであって、本発明を何ら限定するものではない。   The present invention employs the following configuration in order to solve the above problems. Note that the reference numerals in parentheses, supplementary explanations, and the like are examples of the correspondence with the embodiments described later in order to help understanding of the present invention, and do not limit the present invention.

本発明に係る幅木の固定構造は、建枠(4)と、該建枠の第1横材(41)に一方端が係止され該建枠の第2横材(42)に他方端が係止される足場板(5)とを備える足場に取り付けられる幅木(2)の固定構造(1)である。幅木の固定構造は、第1係止部材(11)と、第1軸(12)と、第2係止部材(13)と、付勢部材(14)とを備える。第1係止部材(11)は、上記幅木の一方端部を上記第1横材に係止する。第1軸(12)は、上記幅木の他方端部近傍に上記幅木に垂直な方向に形成される。第2係止部材(13)は、上記第1軸を支点として上記幅木に沿って回動可能に構成される。付勢部材(14)は、上記第2係止部材の上部に係合し、上記第2係止部材の上部を上記幅木の長手方向に付勢可能に構成される。上記付勢部材が上記第2係止部材の上部を上記長手方向に付勢することによって、上記第2係止部材が上記第1軸を支点として回動され、上記第2係止部材の下部が上記第2横材に係合する方向に付勢されて上記第2横材に係止される。   The baseboard fixing structure according to the present invention has one end locked to the building frame (4) and the first cross member (41) of the building frame, and the other end to the second cross member (42) of the building frame. It is the fixed structure (1) of the base board (2) attached to a scaffold provided with the scaffold board (5) by which is locked. The baseboard fixing structure includes a first locking member (11), a first shaft (12), a second locking member (13), and an urging member (14). The first locking member (11) locks one end of the skirting board to the first cross member. The first axis (12) is formed in the direction perpendicular to the skirting board in the vicinity of the other end of the skirting board. The second locking member (13) is configured to be rotatable along the skirting board with the first shaft as a fulcrum. The urging member (14) is configured to engage with the upper portion of the second locking member and to urge the upper portion of the second locking member in the longitudinal direction of the skirting board. The biasing member biases the upper portion of the second locking member in the longitudinal direction, whereby the second locking member is rotated about the first shaft, and the lower portion of the second locking member. Is urged in a direction to engage with the second cross member and is locked to the second cross member.

上記幅木の固定構造によれば、付勢部材が第2係止部材の上部を長手方向に付勢することによって、第2係止部材の下部が第2横材に係合する方向に付勢されて第2横材に係止されるため、幅木が建枠(ここでは、第1横材および第2横材)から外れることを防止できる。また、付勢部材によって第2係止部材を付勢させて、幅木を建枠に簡便に取り付けることができると共に、付勢部材による第2係止部材の付勢を解除することによって、幅木を建枠から簡便に取り外すことができる。   According to the fixing structure of the skirting board, the biasing member biases the upper part of the second locking member in the longitudinal direction, so that the lower part of the second locking member is biased in the direction in which the second locking member is engaged. Since it is biased and locked to the second cross member, it is possible to prevent the baseboard from coming off from the building frame (here, the first cross member and the second cross member). Further, the second locking member can be urged by the urging member so that the baseboard can be easily attached to the building frame, and the urging of the second locking member by the urging member is released, The tree can be easily removed from the building frame.

また、上記第1軸は、上記幅木の他方端部近傍の下端部近傍に形成され、上記付勢部材は、上記幅木の他方端部の上端部近傍において上記第2係止部材の上端部を付勢してもよい。   The first shaft is formed in the vicinity of the lower end near the other end of the skirting board, and the biasing member is positioned at the upper end of the second locking member in the vicinity of the upper end of the other end of the skirting board. The part may be energized.

上記幅木の固定構造によれば、第1軸から第2係止部材の上端部(=付勢部材による付勢位置)までの距離を、第1軸から第2係止部材の下端部(=第2係止部材の第2横材への係合位置)までの距離より大きくすることができる。これにより、「てこの原理」によって、第2係止部材の下端部を第2横材へ付勢する付勢力を大きくすることがことができるため、幅木が建枠から外れることをより確実に防止できる。   According to the fixing structure of the skirting board, the distance from the first shaft to the upper end portion of the second locking member (= the urging position by the urging member) is set to the lower end portion of the second locking member (from the first shaft). = The distance to the engagement position of the second locking member with the second cross member). As a result, it is possible to increase the urging force for urging the lower end portion of the second locking member to the second cross member by the “lever principle”, and thus it is more reliable that the baseboard is detached from the building frame. Can be prevented.

Therefore, it is possible to prevent the worker's walking from being obstructed by the second locking member.

また、上記第2係止部材は、その下端部が上記幅木の長手方向であって上記第2横材に近接する方向に曲がった略L字型に形成された板状部材であってもよい。   Further, the second locking member may be a plate-like member formed in a substantially L shape whose lower end is bent in the longitudinal direction of the baseboard and in the direction close to the second cross member. Good.

上記幅木の固定構造によれば、第2係止部材を構成する略L字型の板状部材を、適正な厚み(例えば、4.5mm)および適正な幅(例えば、25mm)とすることによって、第2係止部材の強度、弾性係数を適正な大きさとすることができる。また、第2係止部材を略L字型に構成することで、第2係止部材が第2横材に係止されやすくすることができる。   According to the fixing structure of the skirting board, the substantially L-shaped plate-like member constituting the second locking member has an appropriate thickness (for example, 4.5 mm) and an appropriate width (for example, 25 mm). Thus, the strength and elastic modulus of the second locking member can be set to appropriate sizes. Further, by configuring the second locking member in a substantially L shape, the second locking member can be easily locked to the second cross member.

また、上記第2係止部材は、当該第2係止部材の下端部に、上記第2横材に嵌合するべく当該第2横材の外周と略同一の内径に形成された断面視円弧状の板状部材(131)を備えてもよい。   Further, the second locking member is formed in a cross-sectional view circle formed at the lower end portion of the second locking member so as to have an inner diameter substantially the same as the outer periphery of the second horizontal member so as to be fitted to the second horizontal member. An arc-shaped plate member (131) may be provided.

上記幅木の固定構造によれば、第2係止部材の下端部に形成された断面視円弧状の板状部材が第2横材に嵌合するため、幅木が建枠から外れることを更に確実に防止できる。   According to the fixing structure of the skirting board, since the plate-like member having a circular arc shape in cross section formed at the lower end portion of the second locking member is fitted to the second cross member, the skirting board is detached from the building frame. Furthermore, it can prevent reliably.

Further, when the operator rotates the grip portion 143C of the first swing member 143 in the right direction with the second shaft 142 as a fulcrum, the third shaft 144 rotates in the right direction. Then, as the third shaft 144 rotates in the right direction, the second swing member 145 moves to the right, and the first swing member 143 moves to the horizontal position (first position as shown in FIG. 9C). When the second rocking member 145 is rotated to the first position, the left end portion of the second swing member 145 urges the upper end portion of the second locking member 13 to the right. Finally, the operator rotates the fixing member 146 to engage with the grip portion 143C (right end portion) of the first swing member 143 to bring the first swing member 143 into the horizontal position (first position). Fix (Fig. 4).

第2係止部材13の付勢を解除する順序は、上記と逆である。まず、作業者は、図4に示す第1揺動部材143の右端部が固定部材146で固定された状態から、固定部材146を回動させて第1揺動部材143の把持部143Cへの係合を解除する(図9(c))。次に、作業者は、第1揺動部材143の把持部143Cを把持し、第2軸142を支点として左上方へ回動させる。この第1揺動部材143の回動に伴って、第3軸144が第2軸142を支点として左上向きに回動し、第2揺動部材145の右端部が、左上向きに移動する。これにより、第2揺動部材145による第2係止部材13の上端部への付勢が解除される(図9(b))。そして、作業者が、第2揺動部材145を第3軸144を支点として右上方に回動させると、第2揺動部材145の左端部と第2係止部材13の上端部との係合が解除される(図9(a))。   The order of releasing the bias of the second locking member 13 is the reverse of the above. First, the worker rotates the fixed member 146 from the state where the right end portion of the first swing member 143 shown in FIG. 4 is fixed by the fixed member 146 to the grip portion 143C of the first swing member 143. The engagement is released (FIG. 9 (c)). Next, the operator grips the grip portion 143C of the first swing member 143 and rotates it to the upper left with the second shaft 142 as a fulcrum. Along with the rotation of the first swing member 143, the third shaft 144 rotates upward with the second shaft 142 as a fulcrum, and the right end of the second swing member 145 moves upward to the left. Thereby, the urging | biasing to the upper end part of the 2nd latching member 13 by the 2nd rocking | swiveling member 145 is cancelled | released (FIG.9 (b)). When the operator rotates the second swing member 145 to the upper right with the third shaft 144 as a fulcrum, the engagement between the left end portion of the second swing member 145 and the upper end portion of the second locking member 13 is established. The match is released (FIG. 9A).

このようにして、第1揺動部材143を第2軸142を支点として回動させることによって、幅木2を建枠4に簡便に取り付けることができると共に、幅木2を建枠4から簡便に取り外すことができる。   In this way, by rotating the first swing member 143 around the second shaft 142 as a fulcrum, the skirting board 2 can be easily attached to the building frame 4 and the skirting board 2 can be easily removed from the building frame 4. Can be removed.

ここで、固定部材146によって第1揺動部材143が固定される様子を図10を用いて説明する。図10は、固定部材146によって第1揺動部材143が固定される様子を示す図である。図10において、第1揺動部材143と固定部材146以外の部材は省略されている。   Here, how the first swing member 143 is fixed by the fixing member 146 will be described with reference to FIG. FIG. 10 is a diagram illustrating a state in which the first swing member 143 is fixed by the fixing member 146. In FIG. 10, members other than the first swing member 143 and the fixing member 146 are omitted.

上述したように、固定部材146は、幅木2の上端部に設置された幅木2に垂直な第4軸147を支点として回動可能に構成される。すなわち、固定部材146は、当該固定部材146の一方端部に設けられた幅木に垂直な方向の第4軸147を支点として回動可能に構成される。固定部材146が回動された場合、固定部材146の他方端部は円弧を描き、第1揺動部材143の端部(右端部)と係合する(図10(b))。ここで、図10に示すように、第1揺動部材143の右端部は、固定部材146の他方端部が描く円弧と略同一のRを有するように形成される。これにより、固定部材146を回動させて第1揺動部材143の右端部に係合させ易い。   As described above, the fixing member 146 is configured to be rotatable with the fourth shaft 147 perpendicular to the skirting board 2 installed at the upper end of the skirting board 2 as a fulcrum. In other words, the fixing member 146 is configured to be rotatable about the fourth shaft 147 in the direction perpendicular to the baseboard provided at one end of the fixing member 146. When the fixing member 146 is rotated, the other end of the fixing member 146 draws an arc and engages with the end (right end) of the first swing member 143 (FIG. 10B). Here, as shown in FIG. 10, the right end portion of the first swing member 143 is formed to have substantially the same R as the arc drawn by the other end portion of the fixing member 146. Accordingly, the fixing member 146 can be easily rotated and engaged with the right end portion of the first swing member 143.

ここで、第1揺動部材143の右端部近傍には、固定部材146の他方端部が描く円弧の半径方向の外向きに突出した凸部143Dが設けられている。第4軸147と凸部143Dの上面との距離は、固定部材146の他方端部が描く円弧の半径と略同一か、当該円弧の半径よりも僅かに大きく設定される。従って、固定部材146が回動された場合に、固定部材146の他方端部が、第1揺動部材143の右端部近傍に設けられた凸部143Dに僅かに接触する。しかしながら、作業者が、所定の力以上でさらに左方向に固定部材146を回動させると、固定部材146は第1揺動部材143の凸部143Dを超えて、図10(c)の位置に回動する。これにより、第1揺動部材143は固定部材146によって水平位置に固定される。   Here, in the vicinity of the right end portion of the first swing member 143, a convex portion 143D protruding outward in the radial direction of the arc drawn by the other end portion of the fixing member 146 is provided. The distance between the fourth shaft 147 and the upper surface of the convex portion 143D is set to be substantially the same as or slightly larger than the radius of the arc drawn by the other end of the fixing member 146. Therefore, when the fixing member 146 is rotated, the other end portion of the fixing member 146 slightly contacts the convex portion 143D provided in the vicinity of the right end portion of the first swing member 143. However, when the worker rotates the fixing member 146 further leftward with a predetermined force or more, the fixing member 146 exceeds the convex portion 143D of the first swinging member 143 and reaches the position of FIG. Rotate. As a result, the first swing member 143 is fixed to the horizontal position by the fixing member 146.

以上のようにして、固定部材146によって付勢部材14(ここでは、第1揺動部材143)が固定されるので、作業者の運搬する建築部材等が付勢部材14と接触することによって、付勢部材14による付勢が解除されることを防止することができるので、幅木2が建枠4から外れることを確実に防止できる。   As described above, the urging member 14 (here, the first swinging member 143) is fixed by the fixing member 146. Therefore, when the building member or the like carried by the operator contacts the urging member 14, Since it can prevent that the urging | biasing by the urging | biasing member 14 is cancelled | released, it can prevent reliably that the baseboard 2 remove | deviates from the building frame 4. FIG.

また、第1揺動部材143の凸部143Dによって、固定部材146が第1揺動部材143の固定を解除する方向(右方向)に回動することを防止することができる。すなわち、固定部材146が図10(c)の位置に回動されている場合において、右方向に回動させると、固定部材146は凸部143Dに接触する。この場合において、固定部材146が図10(c)の位置から図10(b)の位置に回動されるためには、固定部材146は所定の力以上で回動される必要がある。このため、作業者が意図して第1揺動部材143の固定を解除する場合以外は、第1揺動部材143の固定は解除され難い。   Further, the convex portion 143D of the first swing member 143 can prevent the fixing member 146 from rotating in a direction (right direction) in which the first swing member 143 is released. That is, when the fixing member 146 is rotated to the position shown in FIG. 10C, when the fixing member 146 is rotated rightward, the fixing member 146 comes into contact with the convex portion 143D. In this case, in order for the fixing member 146 to be rotated from the position of FIG. 10C to the position of FIG. 10B, the fixing member 146 needs to be rotated with a predetermined force or more. For this reason, the fixing of the first swinging member 143 is difficult to be released unless the operator intentionally releases the fixing of the first swinging member 143.

なお、上述した第1揺動部材143は単なる一例であって、他の変形例に置き換えることができる。図11は、第1揺動部材143の変形例である揺動部材148を示す図である。図11(a)は、第1揺動部材143の変形例である揺動部材148の構成を示す図であり、図11(b)は、揺動部材148の動作を示す図である。   The first swing member 143 described above is merely an example, and can be replaced with another modification. FIG. 11 is a view showing a swing member 148 that is a modification of the first swing member 143. FIG. 11A is a diagram illustrating a configuration of a swing member 148 that is a modification of the first swing member 143, and FIG. 11B is a diagram illustrating an operation of the swing member 148.

図11に示すように、揺動部材148は、孔148Aと、孔148Bと、把持部148Cと、凸部148Dと、付勢手段148Eとを備える。孔148A、孔148B、把持部148Cは、上述した第1揺動部材143の孔143A、孔143B、把持部143Cと同様である。また、揺動部材148の凸部148Dは、第1揺動部材143の凸部143Dと同様である。揺動部材148の右端部近傍には、孔が設けられ、当該孔に凸部148Dが挿通される。凸部148Dは、付勢手段148Eの一方端部にビスやリベット等で固定される。付勢手段148Eの他方端部は揺動部材148の上面部(把持部148Cを構成する部分の一部)にビスやリベット等で固定される。付勢手段148Eの一方端部は、揺動部材148の上面部(把持部148C)に固定されない。従って、図11(b)に示すように、矢印の方向の力Fが凸部148Dに加えられた場合、付勢手段148Eがたわむ。これにより、揺動部材148の凸部148Dは、上方向に付勢された状態で、上下方向に動作可能となる。すなわち、揺動部材148の凸部148Dは、付勢手段148Eによって、固定部材146の他方端部が描く円弧の半径方向(の外向き及び内向き)に動作可能であり、半径方向の外向きに付勢される。このような構成によって、固定部材146を図10(a)の状態から左方向に回動させる場合、作業者は揺動部材148の凸部148Dを下方向に押すことで揺動部材148を図10(c)の位置に回動させることができる。また、揺動部材148の凸部148Dが下方向に押されない場合は、凸部148Dと固定部材146とが接触するため、固定部材146は図10(c)の位置から図10(b)の位置に回動され難い。すなわち、揺動部材148の凸部148Dが固定部材146に接触するため、固定部材146による揺動部材148の水平位置(第1位置)への固定を解除する方向に固定部材146が回動され難い。従って、より確実に揺動部材148を水平位置(第1位置)に固定することができ、付勢部材14をより確実に固定することができる。なお、揺動部材148の凸部148Dを付勢する付勢手段としては、上述した板状の付勢手段148Eに限られない。例えば、凸部148Dを付勢する付勢手段として、コイル状のバネが用いられてもよい。   As shown in FIG. 11, the swing member 148 includes a hole 148A, a hole 148B, a gripping part 148C, a convex part 148D, and an urging means 148E. The hole 148A, the hole 148B, and the grip portion 148C are the same as the hole 143A, the hole 143B, and the grip portion 143C of the first swing member 143 described above. Further, the convex portion 148D of the swing member 148 is the same as the convex portion 143D of the first swing member 143. A hole is provided in the vicinity of the right end of the swing member 148, and the convex portion 148D is inserted through the hole. The convex portion 148D is fixed to one end portion of the biasing means 148E with a screw, a rivet or the like. The other end portion of the urging means 148E is fixed to the upper surface portion of the swing member 148 (part of the portion constituting the grip portion 148C) with screws, rivets, or the like. One end portion of the urging means 148E is not fixed to the upper surface portion (gripping portion 148C) of the swing member 148. Therefore, as shown in FIG. 11B, when the force F in the direction of the arrow is applied to the convex portion 148D, the biasing means 148E bends. As a result, the convex portion 148D of the swing member 148 can be operated in the vertical direction while being biased upward. In other words, the convex portion 148D of the swinging member 148 can be operated in the radial direction (outward and inward) of the arc drawn by the other end portion of the fixing member 146 by the biasing means 148E. Be energized by. With such a configuration, when the fixing member 146 is rotated leftward from the state of FIG. 10A, the operator pushes the convex portion 148 </ b> D of the swinging member 148 downward so that the swinging member 148 is illustrated. It can be rotated to the position 10 (c). Further, when the convex portion 148D of the swing member 148 is not pushed downward, the convex portion 148D and the fixing member 146 come into contact with each other, so that the fixing member 146 is moved from the position of FIG. 10C to the position shown in FIG. It is difficult to rotate to the position. That is, since the convex portion 148D of the swinging member 148 contacts the fixing member 146, the fixing member 146 is rotated in a direction in which the fixing member 146 releases the fixing of the swinging member 148 to the horizontal position (first position). hard. Therefore, the swinging member 148 can be more reliably fixed at the horizontal position (first position), and the biasing member 14 can be more reliably fixed. Note that the urging means for urging the convex portion 148D of the swing member 148 is not limited to the plate-like urging means 148E described above. For example, a coiled spring may be used as a biasing unit that biases the convex portion 148D.

本実施形態では、付勢部材14が支持部材141、第2軸142、第1揺動部材143、第3軸144、第2揺動部材145、および、固定部材146を備える場合について説明したが、付勢部材14が第2係止部材13の上端部を幅木2の長手方向に付勢可能に構成されていればよい。例えば、付勢部材14が、第2係止部材13の上端部に係止される係止部材と、該係止部材を幅木2の長手方向に付勢する部材(例えば、一方端が前記係止部材に係止されたバネを有し、該バネが固有長から伸ばされた状態で、他方端が第2係止部材13から離間する幅木2の所定位置に係止される部材)とを備える形態でもよい。   In this embodiment, the case where the urging member 14 includes the support member 141, the second shaft 142, the first swing member 143, the third shaft 144, the second swing member 145, and the fixing member 146 has been described. The urging member 14 only needs to be configured to be able to urge the upper end portion of the second locking member 13 in the longitudinal direction of the skirting board 2. For example, the urging member 14 is a locking member that is locked to the upper end portion of the second locking member 13 and a member that urges the locking member in the longitudinal direction of the skirting board 2 (for example, one end is A member having a spring locked to the locking member, and being locked at a predetermined position of the baseboard 2 where the other end is separated from the second locking member 13 in a state where the spring is extended from the natural length) The form provided with.

図12は、第2係止部材13に作用するトルクの釣り合いの一例を説明する図である。第2係止部材13の上端部には、付勢部材14から付勢力P1が作用する。そして、第2係止部材13が、第1軸12を支点として回動するため、第2係止部材13の下端部(ここでは、板状部材131)から第2横材42に向けて付勢力P2が作用する。ここで、第1軸12から付勢力P1の作用点までの距離をL1、第1軸12から付勢力P2の作用点までの距離をL2とすると、第2係止部材13に作用する力の釣り合いの関係は、次の(1)式で表される。
P1×L1=P2×L2 (1)
FIG. 12 is a diagram illustrating an example of a balance of torques acting on the second locking member 13. The biasing force P <b> 1 is applied to the upper end portion of the second locking member 13 from the biasing member 14. Since the second locking member 13 rotates about the first shaft 12, the second locking member 13 is attached from the lower end portion (here, the plate-like member 131) of the second locking member 13 toward the second cross member 42. The force P2 acts. Here, when the distance from the first shaft 12 to the application point of the urging force P1 is L1, and the distance from the first shaft 12 to the application point of the urging force P2 is L2, the force acting on the second locking member 13 is The balance relationship is expressed by the following equation (1).
P1 * L1 = P2 * L2 (1)

上記(1)式を付勢力P2について解くと、次の(2)式が得られる。
P2=P1×L1/L2 (2)
ここで、図2(b)に示すように、第1軸12は、幅木2の下端部近傍に形成されているため、距離L1は距離L2より大きい。従って、上記(2)式より、付勢力P2は付勢力P1より大きいため、第2係止部材13を第2横材42に向けてより大きな付勢力P2で付勢することができる。これにより、幅木2が建枠4から外れることを更に確実に防止できる。
When the above equation (1) is solved for the urging force P2, the following equation (2) is obtained.
P2 = P1 × L1 / L2 (2)
Here, as shown in FIG. 2B, since the first shaft 12 is formed in the vicinity of the lower end of the skirting board 2, the distance L1 is larger than the distance L2. Therefore, since the urging force P2 is larger than the urging force P1 from the above equation (2), the second locking member 13 can be urged toward the second cross member 42 with a larger urging force P2. Thereby, it can prevent more reliably that the skirting board 2 remove | deviates from the building frame 4. FIG.

また、第2係止部材13が、幅木2の足場板5と離間する側からの側面視において略L字型に形成された板状部材であるため、第2係止部材13を第2横材42に係止する際の作業が容易になる。すなわち、図2(b)に示すように、第2係止部材13が略L字型に形成されることにより、第2係止部材13の上端部が付勢部材14によって付勢されると、第2係止部材13の板状部材131は第2横材42に係合する。一方、図2(b)において第2係止部材13が直線状に形成されると、第2係止部材13の上端部が付勢部材14によって付勢されも第2係止部材13の板状部材131は第2横材42に係合しない。ここで、第2係止部材13が直線状に形成されたと仮定して、第2係止部材13の上端部を付勢部材14で付勢して第2係止部材13の板状部材131を第2横材42に係合させるためには、第2係止部材13全体を図2(b)に示す位置よりも左側に位置させる必要がある。そうすると、付勢部材14は、必然的に図2(b)に示す位置よりも左側に位置させる必要がある。このような場合において、幅木2を図1に示すように建枠4の縦材43に近接させて設置すると、縦材43が存在するため、付勢部材14を動作させて第2係止部材13を第2横材42に係止させる作業がし難い場合がある。従って、第2係止部材13が幅木2の足場板5と離間する側からの側面視において略L字型に形成されることにより、第2係止部材13を第2横材42に係止する際の作業が容易になる。   Moreover, since the 2nd latching member 13 is a plate-shaped member formed in the substantially L shape in the side view from the side spaced apart from the scaffold board 5 of the base board 2, the 2nd latching member 13 is made into 2nd. The operation | work at the time of latching to the cross member 42 becomes easy. That is, as shown in FIG. 2B, when the second locking member 13 is formed in a substantially L shape, the upper end portion of the second locking member 13 is biased by the biasing member 14. The plate-like member 131 of the second locking member 13 engages with the second cross member 42. On the other hand, when the second locking member 13 is formed in a straight line in FIG. 2B, the upper end portion of the second locking member 13 is urged by the urging member 14, but the plate of the second locking member 13 is used. The shaped member 131 does not engage with the second cross member 42. Here, assuming that the second locking member 13 is formed in a linear shape, the upper end portion of the second locking member 13 is urged by the urging member 14, and the plate-like member 131 of the second locking member 13. In order to engage the second cross member 42, the entire second locking member 13 needs to be positioned on the left side of the position shown in FIG. In this case, the urging member 14 inevitably needs to be positioned on the left side of the position shown in FIG. In such a case, when the skirting board 2 is installed close to the vertical member 43 of the building frame 4 as shown in FIG. 1, the vertical member 43 is present, so that the urging member 14 is operated to perform the second locking. There is a case where it is difficult to work to lock the member 13 to the second cross member 42. Accordingly, the second locking member 13 is formed in a substantially L shape in a side view from the side away from the scaffold plate 5 of the skirting board 2, whereby the second locking member 13 is engaged with the second cross member 42. Work when stopping is easier.

なお、本発明に係る幅木の固定構造および幅木は、上記実施形態に限定されず、下記の形態でも良い。   Note that the baseboard fixing structure and baseboard according to the present invention are not limited to the above-described embodiment, and may be the following forms.

本実施形態では、幅木2の固定構造1が、幅木2を建枠4の横材(ここでは、第1横材41および第2横材42)に係止させる場合について説明したが、幅木2を建枠4の縦材に係止させる形態でもよい。更には、幅木2の固定構造1が、幅木2を建枠4の横材および縦材に係止させる形態でもよい。この場合には、幅木2が建枠4から外れることを更に確実に防止できる。   In this embodiment, the fixing structure 1 of the skirting board 2 demonstrated the case where the skirting board 2 is locked to the cross member (here, the 1st cross member 41 and the 2nd cross member 42) of the building frame 4, A configuration in which the skirting board 2 is locked to the vertical member of the building frame 4 may be employed. Further, the fixing structure 1 of the skirting board 2 may be configured such that the skirting board 2 is locked to the cross member and the vertical member of the building frame 4. In this case, it is possible to more reliably prevent the baseboard 2 from being detached from the building frame 4.

本実施形態では、付勢部材14が第2係止部材13を、第1横材41と第2横材42との間隔を拡げる方向(幅木2の長手方向であって外方(中央から両端に向かう方向)に付勢する場合について説明したが、付勢部材が第2係止部材を、第1横材41と第2横材42との間隔を狭める方向(幅木2の長手方向であって内方(両端から中央に向かう方向))に付勢する形態でもよい。   In the present embodiment, the urging member 14 moves the second locking member 13 in the direction in which the interval between the first cross member 41 and the second cross member 42 is increased (in the longitudinal direction of the skirting board 2 and outward (from the center). The case of biasing in the direction toward both ends has been described, but the biasing member narrows the interval between the first cross member 41 and the second cross member 42 (longitudinal direction of the baseboard 2). However, it may be configured to bias inward (direction from both ends toward the center).

また、本実施形態では、付勢部材14が第2係止部材13の上端部を付勢することで、第2係止部材13の下端部(板状部材131)で第2係止部材13を第2横材42に係止した。他の実施形態では、付勢部材14が第2係止部材13の上端部に限らず、上端部と第1軸12との間の部分(第2係止部材13の上部)を付勢することで、第2係止部材13の下部(下端部と第1軸12との間の部分)で第2係止部材13が第2横材42に係止されてもよい。   In the present embodiment, the urging member 14 urges the upper end portion of the second locking member 13, so that the second locking member 13 is formed at the lower end portion (plate-like member 131) of the second locking member 13. Was locked to the second cross member 42. In another embodiment, the urging member 14 urges not only the upper end portion of the second locking member 13 but also the portion between the upper end portion and the first shaft 12 (the upper portion of the second locking member 13). Thus, the second locking member 13 may be locked to the second cross member 42 at the lower portion of the second locking member 13 (the portion between the lower end portion and the first shaft 12).

本実施形態では、幅木2の固定構造1が幅木2に固定されている場合について説明したが、幅木2の固定構造1が、幅木2に着脱自在に構成されている形態でもよい。   In the present embodiment, the case where the fixing structure 1 of the skirting board 2 is fixed to the skirting board 2 has been described, but the fixing structure 1 of the skirting board 2 may be configured to be detachable from the skirting board 2. .
