Here, the 1st vertical pipe 13 and the 2nd vertical pipe 14 which are each arrange | positioned by the space | interval a are connected by the elongate horizontal pipe (not shown). Further, the adjacent first vertical pipes 13 arranged at the interval b are connected by a short first horizontal pipe (not shown), and the adjacent second vertical pipes 14 are connected by a short first pipe. Two horizontal pipes (not shown) are connected.

The distance a between the adjacent first vertical pipe 13 and the second vertical pipe 14 is, for example, 600 mm or more and 1800 mm or less (for example, 600 mm, 900 mm, 1200 mm, 1500 mm, 1800 mm). Further, the interval b between the adjacent first vertical pipes 13 (the same applies to the adjacent second vertical pipe 14) is narrower than the above-described interval a.
FIGS. 1B and 1C and FIGS. 2A and 2B illustrate the case where the interval a is 1800 mm, and the portion omitted in the drawing is 26 cm.
The unit vertical pipe group described above is usually used by continuously installing a plurality of unit vertical pipe groups around an object for constructing the temporary scaffold 11. For example, one unit vertical pipe group may be used. You can also.

A scaffolding plate 12 is spanned between the adjacent first and second horizontal pipes.
The scaffold plate 12 has a rectangular shape in plan view, and is composed of, for example, a metal plate or an expanded metal (having a diamond-shaped opening) stretched inside a frame made of an angle material. ing.
As a result, the scaffolding plate 12 has a first vertical pipe 13 and a second vertical pipe 14 that are adjacent to each other, a first vertical pipe 13 that is adjacent to the first vertical pipe 13, and a first vertical pipe 13 that is adjacent to each other. It is arranged in a region surrounded by the two vertical pipes 14 and the second vertical pipe 14.

The temporary scaffolding baseboard device 10 shown in FIGS. 1 to 10 is made of a steel material (for example, ordinary steel, carbon steel, high-tensile steel), and the surface thereof is plated with a zinc alloy or the like.
The baseboard device 10 includes a vertical baseboard portion 15a disposed between the first and second vertical pipes 13 and 14 in a standing state, and a scaffold plate 12 from a lower end portion of the vertical baseboard portion 15a. A base plate 15 provided with a horizontal member 15b extending toward the base, and a movable receiving member (a pair) provided at both ends of the vertical base plate portion 15a so as to be rotatable about vertical shafts 16 and 17 That is, it has one movable receiving member 19 and the other movable receiving member 18), and fastening means 20 provided at one end (movable receiving member 19 side) of the vertical base plate portion 15a. It is arrange | positioned along the longitudinal direction. In addition, the baseboard apparatus 10 can be arrange | positioned only on the target object side which constructs the temporary scaffold 11 of the scaffold board 12, only on the opposite side to a target object, or both on the target object side and its opposite side. Hereinafter, the skirting board main body 10 will be described.

As shown in FIGS. 1 (A) to 1 (C) and FIGS. 2 (A) to 2 (C), the skirting board main body 15 has a cross section L of a thin plate material (for example, a plate thickness of about 0.8 to 1.2 mm). It is formed by bending it into a letter shape. Specifically, in the L-shaped thin plate material, the portion in the standing state constitutes the vertical baseboard portion 15a, and the portion in the horizontal state constitutes the horizontal member 15b.
The L-shaped cross section means 90 degrees (right angle), but may be inclined within a range of about ± 2 degrees, for example.

The horizontal member 15b is placed on the scaffolding plate 12 in use (a state where the baseboard device 10 is attached to the temporary scaffold 11). The height of the vertical skirting board portion 15a, that is, the height H from the lower surface of the horizontal member 15b (upper surface of the scaffolding board 12) to the upper end of the vertical skirting board portion 15a is, for example, 10 cm or more (further 15 cm or more). It has become.
The width of the horizontal member 15b (the length along the longitudinal direction of the scaffolding plate 12, that is, the length in the longitudinal direction) is as shown in FIGS. 1 (B), (C), 2 (A), and (B). The width is reduced stepwise toward the scaffold plate 12, but is not limited to this as long as it can be placed on the scaffold plate 12. For example, the width may be gradually reduced, and the same width may be used. But you can.

As shown in FIGS. 1A to 1C and FIGS. 2A to 2C, the front end portion 21 of the horizontal member 15b is hemmed and folded downward. Thereby, for example, it is possible to hide a sharp portion when the horizontal member 15b is molded, and safety can be improved.
Further, the horizontal member 15b is subjected to arc-shaped rib processing in the width direction (longitudinal direction, hereinafter the same), and reinforcing ribs 22 and 23 are formed. Here, the two reinforcing ribs 22 and 23 are formed at intervals in the direction orthogonal to the width direction of the horizontal member 15b (toward the scaffolding plate 12), but one may be used, There may be three or more.
Thereby, since the rigidity of the horizontal member 15b can be improved, for example, the horizontal member 15b can be thinned, and as a result, the weight can be reduced.

At the upper end of the vertical baseboard portion 15a, the entire width direction (longitudinal direction, hereinafter the same) is inside the vertical baseboard portion 15a (in the plan view, on the horizontal member 15b side, that is, on the scaffold plate 12 side, The same applies to the following, and bending processing having an inverted L-shaped cross section is performed, and storage portions 24 and 25 for the movable receiving members 18 and 19 are provided inside both ends of the vertical baseboard portion 15a.
As shown in FIGS. 1A and 1C, the height of the bent tip (lower end) 26 is a position that does not contact the movable receiving members 18 and 19 during rotation. The bent upper surface portion 27 overlaps most of the movable receiving members 18 and 19 stored in the storage portions 24 and 25 in a plan view as will be described later (FIG. 5A). ) And FIG. 8 (A)).

As shown in FIGS. 3A to 3C, the movable receiving member 18 (same as the movable receiving member 19) has a rectangular (may be square) flat seat 28, and stands on both sides of the flat seat 28. It is comprised by the side wall part 29 and 30 used as a pair provided in parallel. Thereby, the movable receiving member 18 has a U-shaped cross section.

As shown in FIGS. 3A to 3C, there is a recess 32 that coincides with the outer peripheral surface 31 of the first vertical pipe 13 (in the case of the movable receiving member 19, the outer peripheral surface 31 of the second vertical pipe 14). Is formed. In addition, the movable receiving member 18 has both side walls 29 and 30 in the longitudinal direction of both sides protruding from the plane seat 28 when viewed from the front (having an H shape). A through hole 32a is formed on one side, and a vertical shaft 16 (vertical shaft 17 on the movable receiving member 19) serving as a rotation center is attached to the through hole 32a.

As shown in FIGS. 1A to 1C, the other movable receiving member 18 is attached to the other side end portion (here, the left side) of the vertical baseboard portion 15 a by an attachment member 33.
As shown in FIGS. 4A to 4C, the mounting member 33 includes a T-shaped flat portion 37 and a narrowed portion of the flat portion 37 (FIGS. 4B and 4C). In this case, the left and right side walls 34 and 35 form parallel pairs. A shaft hole 36 is formed in each of the side wall portions 34, 35, and the vertical shaft 16 attached and fixed to the movable receiving member 18 is rotatably inserted into the shaft hole 36. In addition, since the space | interval of the both-side wall parts 34 and 35 is shorter than the length of the vertical axis | shaft 16, the movable receiving member 18 becomes a structure which covers the both-side wall parts 34 and 35 from the outer side.

As shown in FIGS. 1 (A) to 1 (C) and FIGS. 4 (A) to (C), the mounting member 33 is arranged so that the side wall portions 34 and 35 face the inside of the vertical baseboard portion 15a. The flat portion 37 is disposed in contact with the inner side surface of the vertical baseboard portion 15a, and is fixedly attached through an attachment hole 38 using fastening means (for example, bolts and nuts, the same applies hereinafter). Note that the other end surface 39 (here, the narrowed left end surface) 39 of the attachment member 33 coincides with the width direction end surface 40 of the vertical skirting portion 15a when viewed from the front, but may be displaced.
Further, as shown in FIGS. 1 (C) and 2 (B), the vertical baseboard portion 15a has an upper position of the upper side wall portion 34 and a lower position of the lower side wall portion 35 of the attachment member 33, respectively. Cutout grooves 41 and 42 are formed in the width direction of the vertical baseboard portion 15a, respectively. Thereby, when the movable receiving member 18 rotates, the side wall portions 29 and 30 of the movable receiving member 18 can be inserted through the notched grooves 41 and 42.

Here, the operation state of the movable receiving member 18 will be described with reference to FIGS.

In addition, since the space | interval of the both-side wall parts 44 and 45 is shorter than the length of the vertical axis | shaft 17, the movable receiving member 19 becomes a structure which covers the both-side wall parts 44 and 45 from the outer side.

As shown in FIGS. 1 (A) to (C) and FIGS. 6 (A) to (D), the mounting member 43 is arranged so that both side wall portions 44 and 45 face the inside of the vertical baseboard portion 15a. The flat portion 47 is disposed in contact with the inner side surface of the vertical baseboard portion 15a, and is fixedly attached through a mounting hole 48 using fastening means. Note that one side end surface (here, the narrowed right side end surface) 49 of the attachment member 43 coincides with the width direction end surface 50 of the vertical base plate portion 15a in front view, but may be displaced.
Here, in the widened portion (the left side in FIGS. 6B and 6D) of the flat portion 47 of the mounting member 43, FIGS. 1B and 1C and FIGS. ), A mounting base 52 of a rotation lever (an example of a fixing member) 51 that protrudes toward the vertical skirting board portion 15a and a support portion 53 that restricts the rotation range of the rotation lever 51 are formed. However, these project from the through holes 54 and 55 formed in the vertical skirting board portion 15a, respectively (see FIG. 2B).

As shown in FIGS. 1B and 1C, the rotation lever 51 presses the movable receiving member 19, and the concave portions 32 of the paired movable receiving members 18 and 19 are formed in the first and second vertical pipes 13. , 14 for pressing and holding.

An action part 57 is provided. Further, a horizontal shaft 58 attached to the mounting base 52 of the mounting member 43 is inserted into the through hole 57 a formed in the central portion in the longitudinal direction of the action portion 57, and the longitudinal center of the action portion 57 of the rotation lever 51 is inserted. The part is attached to the vertical baseboard part 15a through a horizontal shaft 58 so as to be rotatable. In addition, since the horizontal axis | shaft 58 is comprised with the volt | bolt and the nut, replacement | exchange is easy.
The guide hole 46 and the rotation lever 51 constitute the fastening means 20 that fixes the skirting board device 10 to the first and second vertical pipes 13 and 14.
Further, as shown in FIGS. 1 (C) and 2 (B), the vertical baseboard portion 15a has an upper position of the upper side wall portion 44 and a lower position of the lower side wall portion 45 of the attachment member 43, as shown in FIGS. Notch grooves 59 and 60 are formed in the width direction of the vertical base plate portion 15a, respectively. Thereby, when the movable receiving member 19 rotates, the both side walls 30 and 29 of the movable receiving member 19 can be inserted into the notched grooves 59 and 60.

Here, the operation state of the movable receiving member 19 will be described with reference to FIGS.
When the baseboard device 10 is not used (for example, when the baseboard device 10 is transported), as shown in FIG. 8A, the movable receiving member 19 is rotated to the inside of the vertical baseboard portion 15a and stored. Place in part 25. At this time, the turning lever 51 is in a horizontal state.
On the other hand, when using the baseboard device 10, as shown in FIGS. 8B and 8C, the movable receiving member 19 is rotated from the inside to the outside of the vertical baseboard portion 15a.
At this time, the vertical shaft 17 provided on the movable receiving member 19 is brought into a state of being brought close to one end portion of the guide hole 46 (the width direction (longitudinal direction end portion side) of the vertical baseboard portion 15a). Further, both side wall portions 30 and 29 of the movable receiving member 19 pass through the notch grooves 59 and 60. The rotating lever 51 is in a vertical state (the state in which the movable receiving member 19 is not pressed) with the gripping portion 56 on the upper side.
