  There are many temporary scaffolding baseboards that have the same shape and structure in order to construct the temporary scaffolding. When transported to a work site or unloaded from various work sites, the thickness direction is stacked up and down in order to improve transport efficiency and handleability. However, when a plurality of temporary scaffolding skirting boards are stacked up and down in this way, positional deviation tends to occur between the temporary scaffolding skirting boards, and it has been effective to produce such positional deviation conventionally. There is not enough ingenuity to prevent it.

  It is an object of the present invention to stack temporary scaffolding skirting boards that can effectively prevent displacement between temporary scaffolding skirting boards when a plurality of temporary scaffolding skirting boards are stacked up and down. It is in providing structure.

  The stacking structure for temporary scaffolds according to the present invention is a stacking structure for temporary scaffolding in which a plurality of temporary scaffolding baseboards are stacked up and down, and two temporary scaffolding baseboards adjacent in the vertical direction One of the temporary scaffolding baseboards is formed with at least a convex part among the convex part and the concave part, and the other temporary scaffolding baseboard is formed with at least a concave part among the convex part and the concave part, and the convex part The two temporary scaffolding baseboards are stacked one above the other when the part is fitted into the concave part.

  In the present invention, one of the two temporary scaffolding baseboards adjacent to the upper and lower sides is formed with at least a convex part among the convex part and the concave part, and the other temporary scaffolding baseboard In addition, since at least a concave portion is formed among the convex portion and the concave portion, and the convex portions are fitted into the concave portion, the two temporary scaffolding baseboards are stacked up and down, so the fitting of the convex portion into the concave portion It is possible to effectively prevent the positional deviation between the two temporary scaffolding baseboards adjacent in the vertical direction.

  In the present invention, one of the two temporary scaffolding skirting boards adjacent to the upper and lower sides is formed with at least a convex part among the convex part and the concave part, and the other temporary scaffolding baseboard The form for forming at least the concave portion among the convex portion and the concave portion is arbitrary. One example thereof is that a plurality of both the convex portions and the concave portions are formed on each of the two adjacent baseboards for temporary scaffolding, and the respective convex portions are fitted into the respective concave portions. It is to stack up and down two temporary scaffolding baseboards having the same shape and structure including the recess.

  According to this, since each of the temporary scaffolding baseboards is formed with a plurality of convex portions and concave portions, a plurality of locations where the convex portions are fitted into the concave portions can be formed. It is also possible to prevent a rotational deviation in the horizontal plane between the two.

  Further, according to this, since each of the temporary scaffolding baseboards can have the same shape and structure including the above-described convex portions and concave portions, a large number of temporary scaffolding baseboards can be effectively mass-produced.

  In addition, when each of the temporary scaffolding baseboards is provided with a protruding portion that protrudes in the thickness direction of these temporary scaffolding baseboards, the protruding portion is formed with one of a convex portion and a concave portion, When the other side of the temporary scaffolding skirting board is stacked up and down by forming the other at a position shifted in the longitudinal direction from the projecting part, and the convex part fitting into the concave part In addition, the protruding portions of the temporary scaffolding baseboards may be displaced in the longitudinal direction of the temporary scaffolding baseboards.

  According to this, even if the temporary scaffolding skirting board is provided with a protruding portion that protrudes in the thickness direction, two temporary scaffolding skirting boards that are vertically adjacent to each other can be moved up and down by fitting the convex part into the concave part. When stacked, the protrusions of these temporary scaffolding baseboards are displaced in the longitudinal direction of the temporary scaffolding baseboards. Therefore, the overall height of the temporary scaffolding baseboards is affected by the protrusions. Can be suppressed to a low level, and the skirting boards for temporary scaffolding that are stacked can be prevented from becoming unstable.

  In addition, in the case where one of the convex portion and the concave portion is formed in the protruding portion of the temporary scaffolding baseboard in this way, and the other is formed at a position shifted in the longitudinal direction from the protruding portion of the temporary scaffolding baseboard. The one side may be a convex portion and the other may be a concave portion, or the one side may be a concave portion and the other may be a convex portion.

  When the above-mentioned one is a convex portion and the other is a concave portion, two concave portions may be formed on one side of the convex portion on both sides in the longitudinal direction from the position of the convex portion. Good.

  According to this, when one concave part which fits a convex part is selected from two concave parts, when stacking two temporary scaffolding baseboards adjacent vertically, for the temporary scaffolding on the lower side The projecting part of the upper temporary scaffolding base can be shifted to either side in the longitudinal direction of the temporary scaffolding baser with respect to the projecting part of the baseboard, and the convex part is fitted. Even if a portion other than the projecting portion of the temporary scaffolding baseboard comes into contact with the concave portion that did not exist, the concave portion does not have the height dimension that is the stacking direction of the temporary scaffolding baseboard. The baseboard for temporary scaffolding can be stacked stably.

  Further, the temporary scaffolding baseboard stacking structure according to the present invention is a temporary scaffolding baseboard stacking structure in which three or more temporary scaffolding baseboards are stacked one above the other, each of the temporary scaffolding baseboards Are provided with protrusions projecting to the back side of the front and back sides which are both sides in the thickness direction of these temporary scaffolding baseboards. Of the three or more temporary scaffolding baseboards that are provided with convex portions and concave portions on both the front side and the back side, and that have the same shape and structure including the convex portions, the concave portions, and the protruding portions. The two temporary scaffolding baseboards adjacent in the vertical direction are such that the protruding parts on the back side of the temporary scaffolding baseboards are shifted in the longitudinal direction of the temporary scaffolding baseboards. Stacked by fitting into the recess on the back side Of the two temporary scaffolding skirting boards, two temporary scaffolding skirting boards adjacent to each other including the temporary scaffolding skirting board have the convex part on the front side fitted into the concave part on the front side. It is characterized by being stacked.

  According to the stacking structure of temporary scaffolding baseboards, each temporary scaffolding baseboard is provided with convex portions and concave portions on both the front side and the back side of these temporary scaffolding baseboards, and three or more are stacked. Of the temporary scaffolding baseboards, two temporary scaffolding baseboards adjacent in the vertical direction are stacked by fitting the back side convex part into the concave part on the back side, and the width of these two temporary scaffolding bases Two temporary scaffolding baseboards adjacent to each other including one temporary scaffolding baseboard among the trees are stacked by fitting the front-side convex parts into the front-side concave parts, so that they are adjacent vertically. Temporary scaffolding baseboards can be stacked by facing each other on the back side and facing each other on the front side, and by repeating this, four or more temporary scaffolding baseboards can be stacked.

  Moreover, according to this stack structure of temporary scaffolding skirting boards, each temporary scaffolding skirting board is projected to the back side of the front side and the back side which are both sides in the thickness direction of these temporary scaffolding skirting boards. Even if the portion is provided, the two temporary scaffolding baseboards adjacent in the vertical direction are in a state in which the protruding portions of these temporary scaffolding baseboards are shifted in the longitudinal direction of these temporary scaffolding baseboards, Since the convex portions on the back side are stacked by fitting into the concave portions on the back side, the effect of the protrusions can be suppressed, and the overall stack height dimension of the temporary scaffolding baseboard can be suppressed to a low level. Scaffolding skirting boards can be prevented from becoming unstable.

  Furthermore, according to the stack structure of the temporary scaffolding baseboards, each temporary scaffolding baseboard can have the same shape and structure including the above-described convex portions, concave portions and protruding portions, so that there are a large number of temporary scaffold widths. It can mass-produce wood effectively.

  In the present invention described above, the convex portions and the concave portions provided on the temporary scaffolding skirting board may be of any form. That is, the convex portion may be a coupling tool for joining members constituting the temporary scaffolding baseboard, or may be a protrusion formed by press working on a part of the members constituting the temporary scaffolding baseboard. The small piece member etc. which were attached to the member which comprises the base board by welding etc. may be sufficient. The recess may be a hole (or a hole), a recess, or a groove. The coupling tool may be a bolt / nut, a rivet, or an eyelet fitting.

  In the case where the convex portion is used as a coupler for joining members constituting the temporary scaffolding baseboard, these members constituting the temporary scaffolding baseboard may be arbitrary members, and an example thereof is the temporary scaffolding. When the baseboard is configured to include a baseboard body and an extension member coupled to the longitudinal end portion of the baseboard body, the member coupled with the coupling tool is It is to make it an extension member.

  According to the present invention, when a plurality of temporary scaffolding skirting boards are stacked one above the other, it is possible to effectively prevent positional deviation from occurring between temporary scaffolding skirting boards.

  The auxiliary member 17 shown in FIG. 2 is formed by bending a plate material. As shown in FIG. 4, the auxiliary member 17 includes a vertical portion 17 </ b> A applied to the outer surface of the web portion 11 </ b> A of the baseboard body 11. The horizontal portion 17B is bent from the lower end of the vertical portion 17A to the back side of the skirting board 10. The vertical portion 17 </ b> A is fastened together with the flange portion 16 </ b> A to the web portion 11 </ b> A by the above-described coupler for connecting the flange portion 16 </ b> B of the cover member 16 to the web portion 11 </ b> A of the baseboard body 11.

  As shown in FIG. 4, a protrusion 27 projecting downward is formed on the horizontal portion 17 </ b> B of the auxiliary member 17 disposed on the lower surface of the skirting board body 11. 10 is continuous over the entire length of the width of the auxiliary member 17 in the left-right direction. This protrusion 27 can be inserted from above into a groove 28 formed in the side end portion shown in FIGS. 5 and 6 on the surface of the cloth plate 3 which is a constituent member of the temporary scaffold 1 of FIG. ing. The groove 28 is one of a plurality of grooves 28 formed in the width direction of the cloth board 3 so as to prevent the operator who rides on the cloth board 3 from slipping.

  In addition, the cloth board 3 is comprised including the some frame member 31 which forms the outline and frame of the cloth board 3, and the top-plate member 32 fixed to the upper surface of these frame members 31, and a baseboard is comprised. 10 is attached to the cloth plate 3 as follows at a side end portion of the cloth plate 3 where a protruding portion 3A protruding downward by the side frame member 31A is formed.

  When the skirting board 10 is attached to the cloth board 3, as shown in FIG. 5, the screw that reaches the upper surface 15B of the hook member 15 to the upper surface of the lower flange part 11C of the skirting board main body 11 by rotation of the screw shaft 13. Lowering to the vicinity of the lower end of the shaft 13, the distance between the lower surface of the baseboard body 11 and the lower side portion 15 </ b> D of the hook member 15 is made larger than the vertical dimension of the protruding portion 3 </ b> A of the cloth board 3. Next, the skirting board 10 is moved inward in the width direction of the cloth board 3 so that the projecting part 3A enters between the lower surface of the skirting board main body 11 and the lower side part 15D of the hook member 15, and then the screw shaft 13 is moved. By rotating the hook member 15 by rotating the head portion 13A and moving the hook member 15 upward, the lower side portion 15D of the hook member 15 and the lower surface of the skirting board body 11 move downward as shown in FIG. The side edge part of the cloth board 3 provided with the protruding part 3A is sandwiched. Thereby, the skirting board 10 is attached to the cloth board 3.

  At the start of the operation of attaching the baseboard 10 to the cloth board 3 performed as described above, the position of the baseboard 10 with respect to the cloth board 3 is not an accurate position as shown in FIG. When the skirting board 10 is displaced by W by the width direction outside of the cloth board 3 from the position where the hook member 15 is moved upward by the rotation of the screw shaft 13, the hook member 15 is inclined upward as described above. Since the extending portion 15E extends obliquely upward from the lower side portion 15D, the obliquely upward extending portion 15E comes into contact with the corner portion 3B inside the protruding portion 3A of the cloth board 3. Then, by continuing the rotation operation of the screw shaft 13 and continuously moving the hook member 15 upward, the position of the skirting board 10 is determined by the guiding action of the inclined upward extending portion 15E inclined as described above. It is automatically corrected inward in the width direction of the plate 3. For this reason, when the side edge part of the cloth board 3 in which the protrusion part 3A is provided is clamped by the lower side part 15D of the hook member 15 and the lower surface of the base board body 11 as shown in FIG. Is attached to a predetermined position of the cloth board 3.

  In addition, after this attachment, the diagonally upward extending portion 15E of the hook member 15 faces the inner surface of the protruding portion 3A of the cloth board 3, so that the skirting board 10 moves outward in the width direction of the cloth board 3. This is prevented by the diagonally upward extending portion 15E, and the skirting board 10 is prevented from moving inward in the width direction of the cloth board 3 by the downward extending portion 15C of the hook member 15.

  Further, at this time, since the protrusions 27 of the auxiliary member 17 are engaged with the grooves 28 of the cloth plate 3, the protrusions 27 and the grooves 28 prevent slippage of the skirting board 10 with respect to the cloth board 3. Positioning has been performed.

Next, the second baseboard 10B from the bottom is stacked on the bottom baseboard 10A with the back side as the lower side, that is, the bottom baseboard 10A and the second baseboard 10B from the bottom are stacked. , The back sides of the bottom skirting board 10A are stacked so that the vertical direction of the bottom skirting board 10A and the vertical direction of the bottom skirting board 10B from the bottom are reversed (FIG. 7). Since the thickness direction of both baseboards 10A and 10B is a vertical direction, in FIG. 7, the horizontal direction of the bottom baseboard 10A and the second level from the bottom are shown. And the second baseboard 10B from the bottom with respect to the lowermost baseboard 10A and the baseboard 10B in the longitudinal direction of the baseboard 10B by the distance L1 in FIG. Just do it. Thereby, the convex portion 51 on the back side of the bottom skirting board 10A is fitted into the concave portion 52 on the back side of the bottom skirting board 10B from the bottom, and the concave portion 52 on the back side of the bottom skirting board 10A is To the convex portion 51 on the back side of the second-stage skirting board 10B. This state is shown in FIG.

  Thus, when the base plate 10B of the 2nd step from the bottom is stacked on the base plate 10A of the lowest step, by fitting the convex portion 51 to the concave portion 52, according to the present embodiment, these base plates It is possible to effectively prevent the positional deviation between 10A and 10B. Moreover, since each of the convex portion 51 and the concave portion 52 into which the convex portion 51 is fitted is provided in the longitudinal direction of the baseboards 10A and 10B, 2 from the bottom with respect to the bottom baseboard 10A. It is also possible to effectively prevent the skirting board 10B at the stage from rotationally shifting in the horizontal direction.

  Further, according to the present embodiment, the base board 10B in the second stage from the bottom with respect to the base board 10A at the lowermost stage is longer than the dimension L2 in the longitudinal direction of the base board 10 with respect to the protruding portion 50 in the longitudinal direction of the base board 10. 8 is shifted by the distance L1 in FIG. 8 and stacked, so that even if the stacking is performed with the back sides of both baseboards 10A and 10B from which the protruding portion 50 protrudes facing each other, these protruding portions 50 can be shifted in the longitudinal direction of the baseboards 10A and 10B, and the protrusions 50 do not come into contact with each other, so that the influence of the protrusions 50 is suppressed and the stacking height of the two baseboards 10A and 10B is lowered. Can be suppressed.

  In addition, according to the present embodiment, there are two concave portions 52 on the back side of the second baseboard 10 </ b> B on both sides in the longitudinal direction of the baseboard 10 with respect to the convex portion 51. Since the distance in the longitudinal direction of the skirting board 10 is the same L1, the protrusion 50 of the skirting board 10B in the second tier from the bottom is extended to the skirting board 10 with respect to the protrusion 50 of the bottom skirting board 10A. When stacking these skirting boards 10A and 10B in the direction of the direction, the protruding part 50 of the bottom skirting board 10B from the bottom with respect to the protruding part 50 of the bottom skirting board 10A is moved in the longitudinal direction of the skirting board 10 The convex portion 51 can be fitted into the concave portion 52 even if the convex portion 51 is displaced to any side, and the concave portion 52 remaining without fitting the convex portion 51 has a width Since it has a shape that does not protrude to the back side of the wood 10, the remaining recess 52 has By lower lip 11E skirting body 11 of the trees 10 abuts, the two skirting 10A and 10B may be stacked to stabilize.

As a result of the above-described stacking, the front side of the second skirting board 10B from the bottom is facing upward as shown in FIG. 7, and on the second skirting board 10B from the bottom, FIG. As shown in FIG. 4, the baseboard 10C at the third level from the bottom is stacked with the front side of the baseboard 10C at the third level from the bottom facing down. That is, both baseboards 10B and 10C are stacked with the front sides facing each other, and this stacking is performed in the vertical direction of the second baseboard 10B from the bottom and the vertical direction of the third baseboard 10C from the bottom. (As described above, since FIG. 7 is a diagram in which the thickness direction of both baseboards 10B and 10C is the vertical direction, in FIG. This is performed by reversing the horizontal direction of the first baseboard 10B and the horizontal direction of the third baseboard 10C from the bottom). In addition, this stacking shifts the bottom skirting board 10C from the bottom to the bottom skirting board 10B from the bottom and the bottom skirting board 10B from the bottom to the bottom skirting board 10A. The distance is shifted by the distance L3 in FIG. 8 in the longitudinal direction of the skirting board 10 toward the opposite side.
As a result, the respective convex portions 53 on the front side of the bottom skirting board 10C of the third step from the bottom are fitted into the respective concave portions 55 on the front side of the bottom skirting board 10B of the second step from the bottom, and the second step from the bottom The respective convex portions 53 on the front side of the baseboard 10B are fitted into the respective concave portions 55 on the front side of the baseboard 10C in the third step from the bottom. This state is shown in FIG.

  In this way, even when the second baseboard 10B from the bottom and the third baseboard 10C from the bottom are stacked, there can be a plurality of places where the convex portion 53 is fitted into the concave portion 55. As with the stacking of the bottom skirting board 10A and the bottom skirting board 10B from the bottom, depending on the location, there is a positional shift between these second and third skirting boards 10B and 10C. While being able to prevent effectively, it can also prevent effectively that the horizontal rotation gap | deviation between these baseboards 10B and 10C arises.

  Further, in the vicinity of each end in the longitudinal direction of the skirting board main body 11, the convex part 53 and the concave part 55 are provided apart in the longitudinal direction of the skirting board 10 by the same distance L3. The base plate 10C of the third step from the bottom with respect to the base plate 10B of the second step from the bottom, and the base plate of the second step from the bottom with respect to the base plate 10A in the longitudinal direction of the base plate 10A It is also possible to stack by shifting the distance L3 to the opposite side to the side where 10B is shifted, so that the bottom skirting board 10A and the bottom skirting board 10C from the bottom are placed in the length direction of the skirting board 10. It is possible to stack them with their positions substantially matched. Further, as described above, by setting L3 = L1, the bottom skirting board 10A and the third skirting board 10C from the bottom are stacked with the position in the length direction of the skirting board 10 accurately matched. be able to.

  Further, the convex portion 53 that remains without being fitted into the concave portion 55 faces the extension member 12 attached to the surface on the back side of the web portion 11 </ b> A of the baseboard body 11. Since the ring-shaped bead portion 54 that protrudes to the front side is formed, the convex portion 53 that is not fitted into the concave portion 55 does not contact the extension member 12 by the bead portion 54. For this reason, it is possible to stably stack the baseboard 10B in the second stage from the bottom and the baseboard 10C in the third stage from the bottom.

  As described above, the baseboards 10A to 10C from the bottom to the third stage are stacked, and the baseboard 10C of the third stage from the bottom is facing down like the bottom baseboard 10A. Therefore, the skirting board 10D in the fourth stage from the bottom is stacked with the front side facing upward, and the skirting board 10E in the fifth stage from the bottom is stacked from the bottom, like the base board 10B in the second stage from the bottom. Like the third-stage skirting board 10B, they are stacked with the front side facing downward, and the stacking is repeated.

  The plurality of skirting boards 10 stacked in this manner are prevented from being displaced due to the projections 51 and 53 on both sides of the front and back being fitted in the recesses 52 and 55, and also prevented from being displaced in the horizontal direction.

  Since each base board 10 can be produced with the same size, shape and structure including the convex portions 51 and 53 on both sides and the concave portions 52 and 55 and the protruding portion 50 on the back side, The skirting board 10 can be mass-produced effectively.

  In addition, the distance in the vertical direction of the skirting board 10 between the convex part 51 on the back side of the skirting board 10 and the lower flange part 11C of the skirting board main body 11, and the top of the recessed part 52 on the back side of the skirting board 10 and the skirting board main body 11 The distance between the base plate 10 and the flange portion 11B in the vertical direction is the same, and, of the two convex portions 53 on the front side of the base plate 10, the convex portion on the upper flange portion 11B side of the base plate body 11 53 and the upper flange portion 11B of the skirting board body 11 in the vertical direction of the skirting board 10 and the two concave portions 55 on the front side of the skirting board 10 on the lower flange portion 11C side of the skirting board body 11 When the skirting boards 10 are stacked one above the other, the skirting boards 10 are stacked up and down by making the distance in the vertical direction of the skirting boards 10 between the recess 55 of the base board 11 and the lower flange part 11C of the base board body 11 equal. Direction perpendicular to the longitudinal direction and the thickness direction (width of the baseboard 10) End of each skirting 10 in direction) can be made to coincide accurately.
