Description

The present invention relates to an assembling structure of a folding stocker in which a column can be tilted with respect to a bottom frame.

At construction sites such as buildings such as houses and buildings, and civil engineering structures such as bridges and tunnels, there are many types of scaffolding members such as columns that stand upright from the installation surface, footboards that are erected between columns, beam members, and handrails. Many are used in each. Therefore, in order to store the scaffold members in an orderly manner or to transport the scaffold members collectively when not in use, a stocker (sometimes referred to as “pallet” or “rack”) on which the scaffold members are loaded is used.

As such a stocker, a foldable stocker capable of tilting the support pillar with respect to the bottom frame has been used. The folding type has an advantage that the stocker is not bulky when not in use.

In a foldable stocker, it is necessary to maintain the assembled state, that is, the state in which the support column is erected at the time of use, but if a lock mechanism that restricts tilting of the support column is provided for that purpose, the configuration of the stocker becomes complicated, There is a problem of high cost.

Further, even if a lock mechanism for restricting the tilt of the column is provided, such a lock mechanism has to be provided near the base end of the column that connects the column and the bottom frame, so that the rigidity of the stocker in the assembled state is high. There is a problem that it is difficult to raise. This problem becomes more prominent as the columns become longer.

Therefore, in view of the above situation, the present invention has a simple structure of a foldable stocker capable of inclining the column with respect to the bottom frame, and can stably maintain the posture at the time of assembling the column. At the same time, it is an object of the present invention to provide an assembly structure capable of increasing rigidity during assembly.

In order to solve the above problems, the assembly structure of the folding stocker according to the present invention (hereinafter, may be simply referred to as “assembly structure”) is
“A stocker for loading a scaffold member, which includes a bottom frame and a foldable stocker that is displaceable between a state of tilting with respect to the bottom frame and a state of standing upright from the bottom frame. When,
Long rod-shaped intermediate member, a pair of long rod-shaped brace members each having one end rotatably connected to one end and the other end of the intermediate member, and end portions of the brace members on the side connected to the intermediate member A pair of hooks provided on the brace, and a handrail for scaffolding provided with a pair of wedge portions provided on the free ends of the brace members, respectively,
The foldable stocker protrudes from a vicinity of a free end of the support column and a locking projection near a base end of the support column or a connecting portion between the support column and the bottom frame, and penetrates in the axial direction of the support column. Further comprising a locking annular portion having a hole for
The pair of hooks in one of the scaffolding handrails are respectively locked to the locking projections of the columns that are adjacent to each other while the columns are erected from the bottom frame. At the same time, the pair of wedge portions are respectively inserted into the locking annular portions in a state where the pair of brace members of the same handrail for scaffolding intersect.”

In this configuration, a foldable stocker (hereinafter, may be simply referred to as "stocker"), in which the support column is displaced from the tilted state with respect to the bottom frame to the upright state, Adjacent columns are connected to each other by an intermediate member of the scaffolding handrail near the free end, and a pair of brace members of the scaffolding handrail are attached to the stocker so as to be braced. Therefore, "not the configuration of the stocker" is effectively utilized by using the handrails for scaffolding existing at the construction site where the stocker is used (site where the scaffolding is temporarily installed), and The posture can be stably maintained, and the rigidity of the stocker at the time of assembly can be increased.

The assembly structure according to the present invention, in addition to the above configuration,
"The foldable stocker is
Multiple mounting plates,
Between two pairs of the columns that are adjacent to each other, a plurality of plate mounting portions for detachably bridging the plurality of mounting plates are provided,
In the plate mounting portion, the mounting plate between the pair of columns and the mounting plate between other columns of the pair are opposed at the same height, and the same mounting plate is bridged. The pillars are provided so that the direction connecting the pair of pillars intersects the direction connecting the pair of pillars to which the pair of hooks of the one handrail for scaffolding are locked. ,
The scaffolding member may be loaded between two mounting plates facing each other at the same height”.

In this configuration, the stocker is provided with a plurality of removable mounting plates, and a plurality of plate mounting portions for mounting the mounting plates are provided on the columns, and the plate mounting portions are mounted on the columns in the same manner. A scaffolding member is stacked between two mounting plates facing each other at a height. Therefore, it is possible to change the interval between the plate mounting portions for mounting the mounting plates and the number of the mounting plates to be used according to the height of the scaffolding member to be stacked in the stacking posture. Thereby, various types of scaffolding members having different heights can be loaded on the stocker having a single structure.

Further, since the mounting plate is bridged between the adjacent columns, the posture in which the columns are erected by the mounting plate is stably maintained, and the rigidity of the stocker is enhanced. In this configuration, the line that connects the pair of support columns over which the mounting plate is bridged and the line that connects the pair of support columns to which the scaffolding handrail is attached intersect, so that depending on the scaffolding handrail and the mounting plate, respectively. The directions in which the effects of stabilizing the posture of the support pillar during assembly and enhancing the rigidity of the stocker intersect are intersected, which has the advantage of synergistically exerting the effects of both.

The assembly structure according to the present invention, in addition to the above configuration,
“The scaffolding member to be loaded has the same configuration as the scaffolding handrail”.

This configuration uses "a part of the scaffolding member that is the loading target of the stocker" in order to stably maintain the posture of the stocker when it is assembled and to increase the rigidity of the stocker during assembly. , Based on original ideas.

As described above, according to the present invention, the foldable stocker capable of tilting the support pillar with respect to the bottom frame has a simple structure, and the posture of the support pillar that is erected can be stably maintained while being assembled. Thus, it is possible to provide an assembly structure capable of increasing rigidity during assembly.

Hereinafter, specific embodiments of the present invention will be described with reference to FIGS. 1 to 7. The assembly structure of this embodiment includes a folding stocker 1 and a scaffolding handrail 110.

First, the configuration of the stocker 1 will be described. The stocker 1 includes a bottom frame 10, a support column 20, a connecting part 30 between the support column 20 and the bottom frame 10, a mounting plate 70, a plate mounting part 40, a storage part 80, and a locking projection 50. The locking annular portion 60 is a main component.

The bottom frame 10 is a frame body formed by a pair of first bars 11 and a pair of second bars 12, and has a rectangular shape (plan view shape) when viewed from directly above. Here, the case where the first bar 11 is longer than the second bar 12 is illustrated. Hereinafter, the axial direction of the first bar 11 will be referred to as the “left-right” direction, and the axial direction of the second bar 12 will be referred to as the “front-back” direction. Further, in a state in which the surface surrounded by the first bar 11 and the second bar 12 in the bottom frame 10 is parallel to the installation surface, the axial direction of the support column 20 erected with respect to the bottom frame 10 is referred to as the “vertical” direction. To call.

The pillar 20 has four rectangular long rods in a cross section orthogonal to the axial direction, and the base ends thereof are connected to the four corners of the bottom frame 10 via the connecting portions 30. Here, of the four columns 20, those connected to both ends of the front first bar 11 are referred to as columns 21, and those connected to both ends of the rear first bar 11 are columns. 22. If there is no particular need to distinguish them, they will be collectively referred to as columns 20. Since the columns 20 stand upright from the four corners of the rectangular bottom frame 10, the direction connecting the pair of columns 21 and 22 is orthogonal to the direction connecting the pair of columns 21, and the pair of columns It is orthogonal to the direction connecting 22.

There are four connecting portions 30 corresponding to the number of the support columns 20, each of which has a U-shaped cross section and includes an intermediate wall 31 and a pair of side walls 32 extending from both sides of the intermediate wall 31 at right angles in the same direction. It is a member. Each of the connecting portions 30 is fixed to both ends of each of the second bars 12 with the U-shaped opening facing inward in the left-right direction, and the first bar 11 has one end in the opening of the connecting portion 30. Is fixed to the connecting portion 30 in the inserted state. The base end of the support column 20 is inserted on the first bar 11 in the opening of the connecting portion 30.

The long holes 15 are formed in each of the pair of side walls 32 of the connecting portion 30 so as to exactly overlap each other. The elongated hole 15 extends in the up-down direction and is inclined so as to extend inward in the left-right direction as it extends upward. In the vicinity of the base end of each of the columns 20, a connecting pin 36 is penetrated so as to project in both directions in the front-rear direction, and the connecting pin 36 is long in a state of penetrating the long holes 15 of the pair of side walls 32. It is prevented from coming off from the hole 15. In this embodiment, the connecting pin 36 is a male screw, and the nuts 37 fastened to both ends of the male screw prevent the connecting pin 36 from coming off the elongated hole 15. Then, the support column 20 is placed on the first bar 11 with the connecting pin 36 positioned at the lower end of the elongated hole 15. The connecting portion 30 having such a configuration has a role of connecting the base ends of the columns 20 to the bottom frame 10 and a role of connecting the first bar 11 and the second bar 12 to form the bottom frame 10. There is.

A leg portion 18 is provided at a lower end of each connecting portion 30 that connects each of the columns 20 to the bottom frame 10. When the leg portion 18 is erected on the installation surface, the leg portion 18 is surrounded by the bottom frame 10. The raised surface is parallel to the installation surface. A ring-shaped metal fitting 19 is fixed to each of the connecting portions 30 so as to project outward. The stocker 1 can be suspended by a rope, a wire, or the like passed through the ring-shaped metal fitting 19.

Since the base end of the support column 20 is connected to the bottom frame 10 via the connecting portion 30 having the above configuration, the support pin 20 is pulled upward while moving the connection pin 36 upward along the elongated hole 15, and the support column 20. By tilting the support column 20 inward in the left-right direction in a state where a gap is formed between the support bar 20 and the first bar 11, as shown in FIGS. 7(a) and 7(b), the support column 20 is It can be in a folded state with respect to the bottom frame 10. As described above, the opening of the connecting portion 30 is directed inward in the left-right direction, and the end portion of the first bar 11 is inserted therein, so that each of the columns 20 overlaps with the first bar 11. It is folded like Although a clearance is provided between the pair of side walls 32 of the connecting portion 30 and the support column 20, the size of the clearance is such that the length of the support column 20 is half the length of the first bar 11. Even if the columns are larger, the columns 21 adjacent to each other and the columns 22 adjacent to each other can be displaced in the axial direction when the columns 20 are tilted (see FIG. 7B), whereby the columns 21 and the columns 22 interfere with each other. The size is set to avoid.

On the contrary, from the state where the support column 20 is tilted with respect to the bottom frame 10, the support column 20 is raised to be at a right angle to the bottom frame 10, and the support pin 20 is pushed down while moving the connecting pin 36 downward along the elongated hole 15. Then, as shown in FIG. 1, the support columns 20 can be set upright from the bottom frame 10.

There are a plurality of plate mounting portions 40 per one column 20. Here, if it is assumed that each of the columns 20 is provided with N plate attachment portions 40, in the state where the columns 20 are erected from the bottom frame 10, the n-th column from the bottom (1≦n≦) of each column 20. The plate mounting portions 40 of N) are at the same height. The plate mounting portions 40 of any of the columns 20 project inward in the front-rear direction, and the plate mounting portions 40 of the columns 21 and 22 standing upright from both ends of the same second bar 12 face each other. ..

The plate mounting portion 40 includes a mounting arm 41 and an insertion arm 42, respectively. The mounting arm 41 is in contact with the outer surface of the column 20 so as to extend in a direction orthogonal to the axial direction of the column 20. The insertion arm 42 extends above the mounting arm 41 and in parallel with the mounting arm 41 with a gap from the outer surface of the support column 20, and has a tip bent upward at a right angle.

Here, the case where the number N of the plate mounting portions 40 per one of the columns 20 is 7 is illustrated, but the stocker 1 of the present embodiment has, in addition to the plate mounting portions 40 provided on the columns 20, The lower end plate mounting portion 40b provided on the connecting portion 30 is provided. The lower end plate mounting portion 40b is composed of a mounting arm 41 and an insertion arm 42 that have the same configurations as those of the plate mounting portion 40, respectively, and has the same height from any of the connecting portions 30 inward in the front-rear direction. It is protruding.

As shown in FIG. 1B, the mounting plate 70 includes a plate body 71 having a flat plate shape and a rectangular outer shape, and a locking piece extending at a right angle from one of a pair of long sides of the plate body 71. 72 and a hanging piece 73 extending from the other of the long sides in the direction opposite to the locking piece 72. The length of the plate body 71 is set to be slightly shorter than the distance between the adjacent columns 21 and 22. Further, in each mounting plate 70, the locking piece 72 is provided with two hole portions 75 that are separated in the longitudinal direction. The distance between the two holes 75 is equal to the distance between the axes of the insertion arms 42 in the plate mounting portions 40 that are at the same height on the adjacent columns 21 and 22, respectively.

The mounting plate 70 having such a configuration can be bridged between the plate mounting portions 40 at the same height on the adjacent columns 21 and 22, respectively, as follows. First, with the mounting plate 70 tilted so that the penetrating direction of the hole portion 75 is the vertical direction, the tip of the insertion arm 42 on the side of the support column 21 is inserted into one of the two hole portions 75, and the other hole is inserted. The tip of the insertion arm 42 on the support column 22 side is inserted into the portion 75. Then, the mounting plate 70 is pushed toward the base of the insertion arm 42 while sliding the edge of the hole 75 with respect to the insertion arm 42. As described above, the insertion arm 42 is bent at a right angle, and the locking piece 72 provided with the hole 75 in the mounting plate 70 is at a right angle to the plate body 71. Accordingly, the plate body 71 becomes parallel to the installation surface. By mounting both ends of the plate body 71 in the longitudinal direction on the mounting arms 41 of the plate mounting portion 40, respectively, the mounting plate 70 is supported by the support plate 21 while the plate body 71 is parallel to the installation surface. It is possible to maintain the state of being bridged between the column and the column 22. The presence of the hanging piece 73 enhances the mechanical strength of the mounting plate 70.

The stocker 1 of the present embodiment further includes a lower end mounting plate 70b that has the same configuration as the mounting plate 70 except for the length in the longitudinal direction. The length of the lower end mounting plate 70b in the longitudinal direction is shorter than the length of the mounting plate 70 in the longitudinal direction, and the lower end plate mounting portion of the connecting portion 30 that connects the adjacent columns 21 and 22 to the bottom frame 10 respectively. It is slightly longer than the distance between the mounting arms 41 at 40b. Further, the distance between the two hole portions 75 penetratingly provided in the locking piece 72 of the lower end placement plate 70b is determined by the lower end of the connecting portion 30 connecting the adjacent columns 21 and 22 to the bottom frame 10. It is equal to the distance between the axes of the insertion arms 42 in the plate mounting portion 40b. The lower end mounting plate 70b having such a configuration is operated in the same manner as when the mounting plate 70 is bridged between the plate mounting portions 40 of the adjacent columns 21 and 22, respectively. Can be bridged between the lower end plate attaching portions 40b of the connecting portion 30 connecting the base plate 10 to the bottom frame 10.

The storage section 80 is for storing the mounting plate 70 and the lower end mounting plate 70b when not in use. The accommodating portion 80 is a member that connects the pair of first bars 11 with its axial direction parallel to the second bar 12, and the cross section orthogonal to the axial direction of the accommodating portion 80 is a U-shape that opens upward. Is. As shown in FIG. 7C, the plurality of mounting plates 70 and the lower end mounting plate 70b can be accommodated in the internal space of the accommodating portion 80 in a stacked state.

In the present embodiment, there are two storage parts 80, and each storage part 80 includes seven mounting plates 70 bridged between the pair of support columns 21 and 22, and a connecting part below them. The size is set so as to accommodate a total of eight lower end mounting plates 70b bridged between 30. Further, each of the storage portions 80 is provided with a small hole portion 82 penetrating a pair of facing side surfaces 81 among the three surfaces forming the U-shape at opposing positions. By passing a bolt 86 with a head through these small holes 82 and fastening it with a nut 87, the mounting plate 70 and the lower end mounting plate 70b are stored by the bolt 86 that crosses the opening of the storage portion 80. The state of being accommodated in the portion 80 is stable.

There is one locking projection 50 for each of the columns 20, and it is provided near the free end of each column 20. Each of the locking projections 50 includes a base portion 51 fixed to the outer surface of the column 20, and a projection portion 52 extending from the base portion 51 in an inverted L shape. The direction in which the projecting portion 52 projects from each of the columns 20 is outward in the front-rear direction.

There is one locking annular portion 60 for each of the columns 20, and in the present embodiment, it is provided in the connecting portion 30 that connects each of the columns 20 to the bottom frame 10. However, in the vicinity of the base end of each of the columns 20. It can be provided. Each locking annular portion 60 has a base portion 61 fixed to the outer surface of the connecting portion 30, and a flat plate-shaped extending portion 62 extending from the base portion 61 so as to form an inverted L shape with the base portion 61. And a hole portion 65 penetrating the extension portion 62. The penetrating direction of the hole portion 65 is parallel to the axial direction of the column 20.

Next, the configuration of the scaffolding handrail 110 will be described. The scaffolding handrail 110 includes an intermediate member 111, a pair of brace members 112, a pair of hooks 115, and a pair of wedge portions 130. The intermediate member 111 is in the shape of a long bar, and has bent portions 111b bent in the same direction at both ends thereof. Each of the pair of brace members 112 is in the form of a long rod that is longer than the intermediate member 111. One end of one brace member 112 is rotatably connected to a bent portion 111b at one end of the intermediate member 111 by a pin 112p, and the other brace member 112 is the other. One end of the brace member 112 is rotatably connected to the bent portion 111b at the other end of the intermediate member 111 by a pin 112p.

Each of the pair of hooks 115 is provided at an end of each of the pair of brace members 112 on the side connected to the intermediate member 111. As a result, when the brace member 112 is rotated with respect to the intermediate member 111, the hook 115 at the end of the brace member 112 also rotates around the axis of the pin 112p.

Each of the pair of wedge portions 130 slides in the internal space of the tubular portion 120 fixed to each free end of the pair of brace members 112, that is, the end opposite to the end where the hook 115 is provided. It is a configuration that does. More specifically, the tubular portion 120 has a flat rectangular tubular shape and includes an upper tubular portion 121 and a lower tubular portion 122 that are separated from each other in the axial direction of the tubular portion. The wedge portion 130 has a first wedge 131 and a second wedge 132 parallel to the first wedge 131, and slides in the tubular portion 120 while being prevented from coming off from the tubular portion 120. The second wedge 132 is longer than the first wedge 131, and the wedge portion 130 is held by the tubular portion 120 in a direction in which the second wedge 132 is closer to the end portion of the brace material 112 than the first wedge 131.

The scaffolding handrail 110 having the above-described configuration has been used for a temporary scaffolding for a long time, and is generally attached to a scaffolding post P including a flange-like attachment 210 as shown in FIG. 3C. It is used as a leading handrail. A plurality of the flange-shaped fixtures 210 are fixed to the scaffolding pillar P standing upright from the installation surface of the temporary scaffolding while being axially separated from each other, and extend in a direction orthogonal to the axial direction of the scaffolding pillar P. The flat plate-shaped flange portion 211 that is projected has holes 215 that penetrate vertically at an angular interval of 90°.

The preceding handrail is installed as a handrail from an existing lower scaffolding floor to a newly installed upper scaffolding floor in a temporary scaffolding in which scaffolding floors are stacked in multiple stages. A method of using the scaffolding handrail 110 as a preceding handrail will be specifically described. An operator on the lower scaffolding floor raises one of the pair of brace members 112 and rotates the brace member 112. As a result, the hook 115 is inserted into the hole 215 of the flange-shaped fixture 210 located at the height of the handrail on the newly installed upper scaffolding floor. Next, the other brace member 112 is raised, and the hook 115 is inserted into the hole 215 of the flange-shaped fixture 210 that is at the same height as the flange-shaped fixture 210 to which the hook 115 is locked.

After that, the pair of brace members 112 are crossed, and the wedge portions 130 at the free ends of the brace members 112 are connected to the flange-shaped fixture 210 at a lower height than the flange-shaped fixture 210 to which the hook 115 is locked. Engage. In that case, the tubular portion 120 holding the wedge portion 130 is arranged so as to sandwich the flange portion 211 from above and below by the upper tubular portion 121 and the lower tubular portion 122, and the first wedge 131 in the hole portion 215. Drop in. The downward movement of the first wedge 131 is guided by the slide of the second wedge 132 in the tubular portion 120. By inserting the first wedge 131 into the hole 215, the wedge 130 is brought into engagement with the flange-shaped fixture 210.

Next, a method of using the stocker 1 having the above configuration and an assembly structure of the stocker 1 using the scaffolding handrail 110 having the above configuration will be described. Here, the case where the target scaffolding member to be loaded on the stocker 1 is the above-mentioned scaffolding handrail 110 is illustrated.

First, with the stocker 1 folded (see FIG. 7 ), its legs 18 are erected on the installation surface. Each of the four columns 20 is raised by the above-described operation, and the columns 20 are erected from the bottom frame 10 (see FIG. 1). The mounting plate 70 and the lower end mounting plate 70b are taken out from the storage portion 80.

The taken-out lower end mounting plate 70b is bridged by the above-described operation between the lower end plate mounting portions 40b located below each of two pairs of the column 21 and the column 22 adjacent to each other (see FIG. 2). .. As a result, the lower end placement plate 70b is bridged directly above the second bar 12 between each pair of two adjacent columns 21 and 22.

Thus, the scaffolding member can be loaded on the stocker 1 by using the two lower end placement plates 70b which are arranged to face each other at the same height. Prior to this, as shown in FIG. 4, the handrail 110 for scaffolding is attached to the stocker 1 to stably hold the posture of the supporter 20 in the standing state during assembly and to increase the rigidity of the stocker 1. The work of loading the scaffolding members can be performed above.

In that case, the scaffolding handrail 110 is attached to at least one of the two columns 21 and between the two columns 22. Taking the case of attaching the scaffolding handrail 110 between the two columns 21 as an example, and explaining with reference to FIGS. 6 and 4, one of the pair of hooks 115 of the scaffolding handrail 110 is provided on one column 21. While hooking on the protrusion 52 of the locking projection 50, the other hook 115 is hooked on the projection 52 of the locking projection 50 provided on the other column 21. Then, the pair of brace members 112 are made to intersect with each other, and the second wedge 132 at the end of one of the brace members 112 is provided at the connecting portion 30 that connects one of the columns 21 to the bottom frame 10. The second wedge 132 at the end of the other brace member 112 is provided in the connecting portion 30 that connects the other column 21 to the bottom frame 10 while being inserted into the hole 65 of the stop annular portion 60 from above. The engaging annular portion 60 is inserted into the hole portion 65 from above. As described above, when the scaffolding handrail 110 is attached to the scaffolding post P, the first wedge 131 of the wedge portion 130 is inserted into the hole 215 of the flange-shaped fixture 210, while the engagement here is omitted. The second wedge 132 is inserted into the hole 65 of the stop annular portion 60.

As a result, the vicinity of the free ends of the adjacent support columns 21, that is, the vicinity of the upper ends of the support columns 21 that are adjacently installed upright, is connected by the intermediate member 111 of the scaffolding handrail 110, and thus the upright installation is performed. The posture of the supporting column 21 is stable. Further, since the pair of brace members 112 that connect the adjacent columns 21 in a crossed state act as braces, the rigidity of the assembly structure in which the columns 21 are erected can be increased.

When the scaffolding member is loaded on the stocker 1 by using the two lower end mounting plates 70b, both ends of the scaffolding member are mounted on the lower end mounting plate 70b. Here, the scaffolding member to be loaded is the scaffolding handrail 110 having the above-described configuration used in the assembly structure. As shown in FIG. 3( b ), the scaffolding handrail 110 to be loaded rotates the pair of brace members 112 about the axis of the pin 112 p, so that the pair of brace members 112 and the intermediate member 111. Both ends are placed on the lower end placement plate 70b in a state of being folded so as to overlap.

When the folded handrails 110 for scaffolding are stacked in a line between the two mounting plates 70b for the lower ends facing each other, the columns 21 and 22 adjacent to each other are directly above the lower plate attaching portion 40b. The mounting plate 70 is bridged between certain plate mounting portions 40 (see FIG. 5). Then, similarly to the above, the folded scaffolding handrails 110 are stacked in a line between the two mounting plates 70 facing each other.

After that, by repeating the same operation, as shown in FIG. 6, the scaffolding handrail 110 in the folded state can be stacked on the stocker 1 in multiple stages. In addition, in the stocker 1 of the present embodiment, the distance between the plate mounting portions 40 adjacent to each of the columns 20 and the distance between the lower end plate mounting portion 40b and the closest plate mounting portion 40 are the same as those of the folded scaffolding hand. It is set to be slightly larger than the height of the slide 110 in the loading posture. Therefore, a large number of scaffolding handrails 110 can be loaded while using the storage space of the stocker 1 without waste.

Although the case where the target scaffolding member to be loaded on the stocker 1 is the scaffolding handrail 110 has been described above, other scaffolding members can be loaded on the stocker 1. In that case, a part of the plurality of plate attachment portions 40 of each support column 20 is selected at predetermined intervals according to the height of the loading target scaffold member in the loading posture, and the mounting plate 70 is attached thereto. As an example, a case where the scaffolding member to be loaded is the scaffolding skirting board 220 will be described with reference to the drawings. As shown in FIG. 8( a ), the scaffolding skirting board 220 has a skirting board main body 221 which is erected between the scaffolding pillars, and a gap between the footboard and the skirting board body 221 which are laterally bridged between the scaffolding pillars. It is a member having an L-shaped cross section, which includes an auxiliary plate portion 222 to be buried, and is bulkier than the scaffolding handrail 110 in the folded state. Therefore, here, as shown in FIG. 8B, among the seven plate mounting portions 40 included in each of the columns 20, the first, third, fifth, and seventh plate attachments from the free end of the column 20 are performed. The mounting plate 70 is attached only to the portion 40, and the scaffold skirting boards are stacked in four stages.

It should be noted that a scaffold member having a length shorter than the distance between two adjacent support columns 21 and two adjacent support columns 22, in other words, the distance between two mounting plates 70 facing each other at the same height. It is also assumed that a scaffold member having a short length is desired to be loaded on the stocker 1. In that case, the intermediate support column 90 as shown in FIG. 9A can be used. The intermediate column 90 includes a plurality of plate attachment portions 40c including a mounting arm 41 and an insertion arm 42 at predetermined intervals, like the plate attachment portion 40 included in the column 20. Further, a flat plate-shaped base 91 larger than the outer shape of the cross section orthogonal to the axial direction of the intermediate support column 90 is fixed to the lower end of the intermediate support column 90, and two holes 95 are formed in the base 91. It penetrates symmetrically with respect to the central axis.

On the other hand, a plurality of holes 15 are formed in the pair of first bars 11 of the stocker 1. These holes 15 form a pair with two adjacent holes, and the distance between the pair of holes 15 is set to be equal to the distance between the two holes 95 provided in the base 91 of the intermediate column 90.

With such a configuration, the intermediate support column 90 is fixed to the first bar 11 by fastening a bolt or the like passed through the hole portion 95 of the base 91 through the hole portion 15 of the first bar 11 to fix the intermediate column 90 to the first bar 11, as shown in FIG. ), the intermediate support column 90 can be erected from the bottom frame 10 between the two support columns 21 and between the two support columns 22. At that time, depending on the length of the scaffolding member to be loaded, two pairs of hole portions 15 are selected from the plurality of hole portions 15 in each of the first bars 11 so as to be in the same position in the pair of first bars 11. To do. Further, the pair of intermediate columns 90 located at the same position in the pair of first bars 11 are fixed to the first bars 11 so that the respective plate mounting portions 40 project inward in the front-rear direction.

In this way, by adding the two pairs of intermediate columns 90 to the stocker 1, the mounting plates 70 can be bridged between the two pairs of intermediate columns 90 facing each other in the front-rear direction. The scaffolding members can be loaded on the stocker 1 by placing both ends of the scaffolding members on the two mounting plates 70 facing each other at the same height in the direction. Then, by connecting the two pillars 21 and the two pillars 22 with the scaffolding handrail 110 in the same manner as described above, the postures of the pillars 21 and 22 in the standing state can be stabilized. In addition, the rigidity of the stocker 1 at the time of assembly can be increased.

As described above, according to the present embodiment, regarding the folding stocker 1 used in the temporary scaffold, the posture at the time of assembling with the columns 20 standing is present in the temporary scaffold instead of the configuration of the stocker 1 itself. By effectively utilizing the scaffolding handrail 110, it can be easily stabilized, and the rigidity of the stocker 1 at the time of assembly can be easily increased.

When the loading target of the stocker 1 is the scaffolding handrail 110, the assembly structure of the stocker 1 is formed by utilizing a part of the scaffolding member itself of the loading target, which is based on an original idea. ..

Further, since the detachable mounting plates 70 can be mounted between the adjacent columns 21 and 22 at different intervals and different numbers, the stockers 1 having a single configuration have different heights in the loading posture. Various types of scaffolding members can be loaded. Further, since the stocker 1 is provided with the storage portion 80 capable of storing the removable mounting plate 70, it is easy to store the mounting plate 70 and manage its members when not in use.

In addition, when the stocker 1 additionally includes the intermediate support column 90, even a scaffolding member having a length shorter than the distance between the two support columns 21 and the distance between the two support columns 22 is loaded on the stocker 1. be able to.

Although the present invention has been described above with reference to the preferred embodiments, the present invention is not limited to the above-described embodiments, and various improvements are made within the scope not departing from the gist of the present invention as shown below. And the design can be changed.

For example, in the above, the case where the lower end mounting plate 70b is attached to the lower end plate mounting portion 40b and the scaffolding member is mounted on the two opposing lower end mounting plates 70b has been exemplified, but the lower end plate mounting portion 40b and A stocker that does not include the lower end mounting plate 70b may be used. When stacking the scaffolding members on such a stocker in multiple stages, the bottommost scaffolding member can be directly placed on the pair of second bars 12. In that case, the height position of the accommodating portion 80 is set to a height that does not interfere with the scaffolding members placed on the pair of second bars 12.

Further, in the above, the procedure of attaching the scaffolding handrail 110 to the stocker 1 prior to loading the scaffolding member after the pillar 20 is erected from the bottom frame 10 has been exemplified, but the procedure is not limited to this procedure. The scaffolding handrail 110 may be attached to the stocker 1 after the scaffolding members are stacked in multiple stages.
