  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.

  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. .

  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.

  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.

  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.

  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.

  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.

  In addition, the second locking member may be disposed along a surface on a side away from the scaffold plate.

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).

  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).

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

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)

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.

  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.

  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.

  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.

  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).

  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).

  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. .
