<Embodiment 1>
A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a view for explaining a scaffolding plate 1. FIG. 2 is a view for explaining the gap 4 formed between the scaffold plate 23 and the protruding scaffold plate 32. FIG. 3 is a perspective view showing an example of the configuration of the scaffold plate 1.
FIG. 4 is a plan view showing an example of the configuration of the scaffolding plate 1. FIG. 5 is a front view showing an example of the configuration of the scaffolding plate 1. FIG. 6 is a front view showing an example of another configuration of the scaffolding plate 1. FIG. 7 is a diagram illustrating an example of a state in which the scaffolding plate 1 is placed on the scaffolding plate 23 and the scaffolding plate 32. FIG. 8 is a diagram illustrating an example of another configuration of the scaffolding plate 1.

  In the first embodiment of the present invention, as shown in FIG. 1, a scaffold plate 1 placed on a scaffold 2 and a protruding scaffold 3 will be described. As shown in FIG. 2, a gap 4 is formed between the scaffold 2 and the protruding scaffold 3. By placing the scaffolding plate 1 described in the present embodiment on the scaffold 2 and the protruding scaffold 3 (that is, placing on the gap 4), as shown in FIG. The gap 4 can be filled. As a result, it is possible to reduce the possibility that a person or an object will fall from the gap 4. That is, it is possible to install the protruding scaffold 3 on the scaffold 2 without sacrificing safety.

  Referring to FIG. 1, a scaffolding plate 1 in this embodiment includes a scaffolding plate 23 (scaffolding plate for scaffolding) that is a scaffolding plate spanned between cross members 22 of the scaffolding 2, and a protruding scaffolding 3. Are placed on a protruding scaffolding plate 32 (scaffolding plate for a protruding scaffold) that is a scaffolding plate spanned between the support members 31. In other words, it can be said that the scaffolding plate 1 in the present embodiment is disposed between the beams formed by the cross member 22 and a part of the support 31.

  Here, the scaffold 2 on which the scaffolding plate 1 is placed and the splash scaffold 3 will be briefly described. Referring to FIG. 1, the scaffold 2 has four metal columns 21 having a jack portion 211 formed at the lower end and extending in the vertical direction. For example, each of the four support columns 21 is installed at a position corresponding to each vertex of a rectangular shape in plan view.

  Of the four columns 21, the two columns 21 on the short side in a plan view are connected to each other by a metal cross member 22 (part of a beam) at a predetermined height. In other words, the cross member 22 that connects the pair of support columns 21 is provided between the pair of support columns 21 on the short side in a plan view. Further, as described above, the four support columns 21 are installed at positions corresponding to the vertices of a rectangular shape in plan view. Therefore, there are two short sides, and the scaffold 2 has a pair of structures in which the pair of support columns 21 are connected by the cross member 22.

  In addition, the cross member 22 is provided between the two support | pillars 21 so that it may become in parallel with the ground in which the scaffold 2 is installed, for example. However, when installing the scaffold 2 on an inclined structure such as a roof, the cross member 22 may not be parallel to the inclined structure on which the scaffold 2 is installed. Further, the height of the cross member 22 formed on one short side and the height of the cross member 22 formed on the other short side are adjusted to be, for example, the same (not necessarily the same). Absent).

  A scaffolding plate 23 (scaffolding plate for scaffolding) is bridged between the two cross members 22 (connected and arranged). The scaffold plate 23 is, for example, a substantially rectangular metal plate, and has a length in the long side direction that is approximately the same as the length between the two support columns 21 on the long side in a plan view. Yes. In this way, the scaffolding plate 23 is bridged between the cross members 22 that connect the columns 21 to each other. In the case shown in FIG. 1, three scaffold plates 23 are bridged, but the number of scaffold plates 23 bridged between the cross members 22 is not limited to three. For example, one or two scaffold plates 23 may be bridged between the cross members 22, or four or more scaffold plates 23 may be bridged.

  Further, between the two struts 21 on the long side of the four struts 21 in plan view and below the scaffolding plate 23, a bracing 24 made of a pair of metal diagonal members is formed. ing. Furthermore, a metal reinforcing member 25 is formed between two struts 21 on the short side in the plan view and below the cross member 22. As described above, the four support columns 21 are reinforced by the braces 24 and the reinforcing members 25.

  For example, the scaffold 2 is formed as described above.

  A protruding scaffold 3 is installed on one of the scaffolds 2 on the long side in plan view. For example, as shown in FIG. 1, each of the two support columns 21 is provided with a support tool 31 such as a metal bracket. Further, a protruding scaffold plate 32 (a scaffolding plate for a protruding scaffold) is bridged between the pair of supports 31 (connectedly arranged).

  In other words, the cross member 22, which is a beam connecting the columns 21, is extended in the direction opposite to the direction in which one column 21 is connected to the other column 21 by the support 31. It can be said that the beam formed by the cross member 22 and the beam formed by the support 31 are connected.

  Note that the height of the protruding scaffold plate 32 is adjusted to be the same as that of the scaffold plate 23, for example.

  Thus, according to the scaffold 2 and the protruding scaffold 3 in the present embodiment, the scaffold plate 23 and the protruding scaffold plate 32 are arranged with the support column 21 interposed therebetween. In addition, as shown in FIG. 2, when the protruding scaffold 3 is installed on the scaffold 2, a gap 4 is generated between the scaffold plate 23 and the protruding scaffold plate 32.

  The scaffold plate 1 is placed on the scaffold 2 having the above-described configuration and the protruding scaffold 3, so that the scaffold 1 is placed on the gap 4 formed between the scaffold 2 and the protruding scaffold 3. Deploy. The scaffolding plate 1 is supported by the scaffolding plate 23 and the protruding scaffolding plate 32 while being placed on the scaffolding plate 23 and the protruding scaffolding plate 32.

  As shown in FIG. 3, the scaffolding plate 1 is composed of a plate-like member 11 having a substantially rectangular shape. The plate-like member 11 has, for example, a length in the long side direction of about 1829 mm and a length in the short side direction of about 300 mm.

  As shown in FIGS. 3 and 4, a concave insertion portion 111 is formed in the middle of the end portion on the short side of the plate member 11 in the thickness direction of the plate member 11. ing. In other words, when the plate-like member 11 out of the plate-like member 11 is laid out on the scaffold plate 23 and placed on the scaffold plate 32, the cross member 22 that is a beam or the place on the support tool 31 side The insertion part 111 is formed (refer FIG. 1 etc.).

  For example, the insertion part 111 has a length in the short side direction of the plate-like member 11 of about 150 mm and a depth (the length in the long side direction of the plate-like member 11) of about 20 mm. In the present embodiment, the depth of the insertion portion 111 is adjusted to be, for example, about half the diameter of the support column 21. Note that when the overlapping portions 113 and 114 described later are formed on the plate-like member 11, the insertion portion 111 may have a depth longer than the diameter of the column 21. The size of the insertion part 111 may be other than those exemplified above.

  As shown in FIG. 1, at least a part of the column 21 is inserted into the insertion portion 111. In a state where the support column 21 is inserted through the insertion portion 111, the support column 21 comes into contact with the insertion portion 111 when the plate-like member 11 is moved in the short side direction or the long side direction. Therefore, the movement of the plate-like member 11 in the short side direction and the long side direction is limited. In other words, the insertion portion 111 locks the plate-like member 11 to the support column 21 and also has a function as a locking portion that prevents the plate-like member 11 from being displaced and a displacement prevention portion.

  Further, for example, two through holes 112 penetrating in the thickness direction of the plate-like member 11 are formed around the insertion portion 111 of the plate-like member 11 (predetermined portions close to the insertion portion 111). For example, the through hole 112 is formed at a position corresponding to a position 30 mm from the short side end of the plate-like member 11 and a position 75 mm from the long side end. The through hole 112 may be formed at a place other than the above-described examples. A connection member (not shown) such as a string is inserted through the through hole 112. A connecting member such as a string inserted through the through hole 112 is used when connecting to another adjacent plate-like member 11.

  Moreover, as shown in FIGS. 3 and 5, the plate-like member 11 has a predetermined thickness, for example. Although the thickness of the plate-like member 11 is not limited, for example, the plate-like member 11 desirably has a thickness of about 15 mm.

  In addition, the plate-shaped member 11 in this embodiment is a product made from polyethylene, for example. The inventor has also made a prototype of the rubber plate-like member 11 and the like, but it has been confirmed that it is difficult for the rubber plate-like member 11 to have the necessary strength for ensuring safety. For example, by using the polyethylene plate-like member 11 having a thickness of approximately 15 mm, it is possible to realize the scaffolding plate 1 having a strength necessary for ensuring safety.

  The above is an example of the structure of the scaffolding plate 1 described in the present embodiment. By using the scaffolding plate 1 having the above-described configuration, the gap 4 can be filled in a plan view when the scaffolding plate 1 is protruded from the scaffold 2 and placed on the scaffold 3. As a result, it is possible to reduce the possibility that a person or an object will fall from the gap 4. That is, it is possible to install the protruding scaffold 3 on the scaffold 2 without sacrificing safety.

  In addition, you may form the superimposition part 113,114 used when overlapping with the other adjacent plate-shaped member 11 in the edge part of the short side of the plate-shaped member 11. FIG. The overlapping portion 113 is provided on one of the end portions on the short side of the plate-like member 11. The overlapping portion 113 is formed, for example, by cutting out a predetermined range on the upper side of the end portion (forming a cut portion). The overlapping portion 114 is provided on the other of the end portions on the short side of the plate-like member 11. The overlapping portion 114 is formed, for example, by cutting a predetermined range on the lower side of the end portion (forming a cut portion). Note that the overlapping portion 113 and the overlapping portion 114 are formed to have shapes corresponding to each other. For example, a portion where the overlapping portion 114 of the other plate-like member 11 adjacent to the overlapping portion 113 (or the overlapping portion 113 of the other plate-like member 11 adjacent to the overlapping portion 114) is overlapped, The thickness is the same as the thickness of the other part of the plate-like member 11. As described above, the overlapping portions 113 and 114 that can be overlapped with other plate-like members 11 may be formed at the end portion on the short side of the plate-like member 11.

  FIG. 7 shows an example when the plate-like member 11 shown in FIG. 6 is overlapped with another plate-like member 11 that is opposite to and adjoins the end of the plate-like member 11. Referring to FIG. 7, by forming the overlapping portions 113 and 114 on the plate-like member 11, it is possible to overlap the other adjacent plate-like members 11 without interfering with each other in the thickness direction.

  When the overlapping portions 113 and 114 are formed on the plate-like member 11 in this way, the through-hole 112 formed in one plate-like member 11 and the other plate-like member 11 are formed when the overlapping portions 113 and 114 are formed. It is desirable to adjust the formation position of the through hole 112 so that an integrated through hole is formed by the formed through hole 112. Thereby, it becomes possible to easily connect the two plate-like members 11 in a state where they are overlapped. Further, when the overlapping portions 113 and 114 are formed on the plate-like member 11, the plate-like member 11 has a through-hole for a column in the thickness direction through which the column 21 is inserted instead of the insertion portion 111. It doesn't matter.

  Further, an overlapping portion having a concave portion and a convex portion at corresponding positions may be formed at the end portion on the short side of the plate-like member 11 as in the overlapping portions 115 and 116 in FIG. Absent. Thus, the shape of the overlapping portions 113 and 114 (the overlapping portions 115 and 116) is not particularly limited.

  Moreover, there are various sizes of the scaffold 2 on which the scaffolding plate 1 is installed and the protruding scaffold 3. For this reason, a plurality of scaffolding plates 1 having different sizes may be prepared and used depending on the size of the scaffold 2 or the protruding scaffold 3 actually used.

  As the size of the scaffolding plate 1, for example, in addition to those exemplified above, the length in the long side direction is 1524 mm, the length in the short side direction is 300 mm, and the length in the long side direction is 1219. The length in the short side direction is 300 mm, the length in the long side direction is 914 mm, the length in the short side direction is 300 mm, the length in the long side direction is 610 mm, and the length in the short side direction is 300 mm. Various things are possible. The scaffold plate 1 may have a size other than those exemplified above.

  Moreover, the structure of the scaffold 2 and the protrusion scaffold 3 illustrated by this embodiment is an example to the last. The scaffold 2 and the protruding scaffold 3 may have a configuration different from the configuration exemplified in the present embodiment.

  As mentioned above, although this invention was demonstrated with reference to each said embodiment, this invention is not limited to embodiment mentioned above. Various changes that can be understood by those skilled in the art can be made to the configuration and details of the present invention within the scope of the present invention.
