As shown in FIG. 1, the suspended scaffolding device 1 according to the first embodiment includes a plurality of scaffolding units A connected and arranged in the depth direction and the width direction, respectively.

As shown in FIG. 2, the vertical beam 2 includes a beam main body 5, and a hanging material bracket 6 provided at one end of the beam main body 5 to which a chain C as a hanging material for suspending the vertical beam 2 can be attached. , can be connected to a first connecting member 7 provided on the side opposite to the beam body of the hanging material bracket 6 and to a first connecting member 7 of another longitudinal beam 2 provided at the other end of the beam body 5 and adjacent in the depth direction. The hanging member bracket 6 and the first connecting member 7 constitute a connecting member J. Further, each end of the horizontal beam 3 is connected to the first connecting member 7 of the vertical beam 2 adjacent to each other in the width direction. In addition, in FIG. 1, in order to make it easier to understand the structure of the suspended scaffolding device 1, there are places where the scaffolding boards 4 are not installed, but in reality, the scaffolding boards 4 are installed without any gaps.

As shown in FIG. 1, by connecting the lower end of a chain C, which is a hanging member whose upper end is connected to a building or structure such as a bridge or a building, to a connecting member J, the suspended scaffolding device 1 It is suspended from a building or structure via C to provide a scaffold for workers who perform construction or maintenance work on the building or structure.

Hereinafter, each part of the suspended scaffolding device 1 of the first embodiment will be explained in detail. As shown in FIG. 2, the longitudinal beam 2 of this embodiment includes a beam main body 5, a coupling member J provided at one longitudinal end of the beam main body 5, and a coupling member J provided at the other longitudinal end of the beam main body 5. A second connecting member 8 is provided.

As shown in FIG. 2(A), the beam main body 5 is vertically spanned between an upper chord member 50 and a lower chord member 51 that are vertically opposed and arranged parallel to each other, and an upper chord member 50 and a lower chord member 51. A beam member having a truss structure is provided with a plurality of bundle members 52 that connect an upper chord member 50 and a lower chord member 51, and a plurality of diagonal members 53 that are diagonally spanned between the upper chord member 50 and the lower chord member 51. It becomes.

In this embodiment, the beam body 5 has a truss structure in order to ensure its strength, but the structure of the beam body 5 is not limited to the truss structure as long as the necessary strength is ensured. .

As shown in FIGS. 2(A) and 2(B), the upper chord member 50 includes a flat plate portion 50a extending along the longitudinal direction of the beam main body 5, and a flat plate portion 50a extending along the longitudinal direction of the beam main body 5 from the upper surface of the flat plate portion 50a. It includes a pair of positioning pieces 50b, 50b that stand up along the direction, and a holding piece 50c that is provided on the lower surface of the flat plate part 50a and holds the bundle material 52 and the diagonal material 53. Further, as shown in FIG. 2(B), a pair of hook holes 50d, 50d adjacent to each other in the width direction are provided in a portion of the flat plate portion 50a on the outside of the positioning pieces 50b, 50b in the width direction. 5 are arranged at three locations at predetermined intervals along the longitudinal direction. The intermediate beam 10 can be connected to the vertical beam 2 by inserting hook portions 12 provided at each end of the intermediate beam 10, which will be described later, into the hook hole 50d.

Next, the coupling member J will be explained in detail. As shown in FIG. 3, the coupling member J of this embodiment includes a hanging material bracket 6 provided at one end of the beam main body 5 to which the chain C can be attached, and a hanging material bracket 6 provided on the opposite side of the beam main body. It has a first connecting member 7.

As shown in FIG. 3A, the suspension bracket 6 of this embodiment includes a pair of upper and lower plates 60 and 61 connected to one end of the upper chord member 50 and the lower chord member 51 of the beam main body 5, respectively, and an upper plate. 60 and a cylindrical connecting portion 62 that connects the lower plate 61.

Note that each plate 60, 61 of this embodiment is formed into an octagonal shape by cutting off four corners of a square plate, as shown in FIG. 3(A). The shape is just an example, and is not limited to the above shape, and may be circular or square. Furthermore, the shape of the connecting portion 62 is not limited to a cylindrical shape, and may be, for example, a rectangular tube shape.

Further, in this embodiment, the hanging material bracket 6 is integrally attached to the beam body 5 by welding, but the method of attaching the hanging material bracket 6 to the beam body 5 is not particularly limited, and for example, The hanging material bracket 6 may be removably attached to the beam body 5 with bolts and nuts.

Further, in the center of the upper plate 60, as shown in FIG. 3(A), a chain fixing hole 63 to which the lower end of the chain C can be connected is provided. Specifically, as shown in FIG. 3A, the chain fixing hole 63 of this embodiment includes a center hole 63a through which the chain C can be inserted, and a center hole 63a that allows the chain C to pass therethrough, and a center hole 63a that allows the chain C to pass through. It has four protruding holes 63b extending in a cross shape. Furthermore, a notch 63c is formed in the upper plate to cross each of the protruding holes 63b in the extending direction of the protruding holes 63b.

Here, a procedure for attaching the lower end of the chain C to the hanging material bracket 6 will be explained. First, with the chain C inserted through the center hole 63a, the chain C is moved laterally and inserted into any protrusion hole 63b. At this time, the width of the protruding hole 63b is set to be wider than the thickness of each ring Ca constituting the chain C and narrower than the width, so the chain C is inserted into the protruding hole 63b. Then, the ring Ca above the upper plate 60 and the ring Ca below the upper plate 60 come into contact with the upper plate 60, and movement in the vertical direction is restricted.

Next, as shown in FIG. 4, with the chain C inserted into the protruding hole 63b, the chain fixing plate 64 is inserted into the notch 63c, and the chain fixing plate 64 is inserted into the hole 64a provided at the upper end of the chain fixing plate 64. A restraint band 65 is passed through the ring Ca of the chain C, and the chain fixing plate 64 and the chain C are fixed with the restraint band 65. This also restricts the lateral movement of the chain C, so that the lower end of the chain C is attached to the hanging material bracket 6.

As described above, the hanging material bracket 6 of this embodiment has the cross-shaped chain fixing hole 63, and can hold the chain C inserted into any of the four protruding holes 63b. Therefore, even if the horizontal position of the chain C is slightly deviated from the horizontal position of the hanging material bracket 6, the attachment position of the chain C can be finely adjusted.

However, the configuration of the hanging material bracket 6 described above is one example, and the configuration of the hanging material bracket 6 is not particularly limited as long as the chain C as a hanging material can be attached. Furthermore, the hanging material for suspending the vertical beam 2 does not need to be the chain C; for example, the hanging material may be a wire rope.

Next, as shown in FIG. 3, the first connecting member 7 of this embodiment is a rectangular flat plate extending from the upper plate 60 and the lower plate 61 of the hanging material bracket 6 toward the side opposite to the beam body. A pair of upper and lower first connecting pieces 70, 70 are provided. Each first connecting piece 70 also has fixing holes that are arranged side by side along the extension direction of the first connecting piece 70 in order from the beam main body 5 side and face each other in the vertical direction, as shown in FIG. 3(A). A detent hole 70a and a detent hole 70b are respectively formed.

Further, as shown in FIG. 3(B), between the pair of upper and lower first connecting pieces 70, 70, there is a first guide tube 71 whose inside communicates with the fixing holes 70a, 70a facing each other, and a first guide tube 71 whose inner part communicates with the fixing holes 70a, 70a facing each other, and A second guide tube 72, which is internally communicated with the stop holes 70b and 70b, is bridged over each of the second guide tubes 72, respectively. However, these guide tubes 71 and 72 may be omitted.

Further, as shown in FIG. 3(A), a pair of upper first connecting pieces 70 are arranged side by side in the width direction of the first connecting piece 70 in a portion of the upper first connecting piece 70 that is closer to the hanging material bracket 6 than the fixing hole 70a. Hook holes 70c, 70c are formed. As will be described in detail later, one end of the cross beam 3 can be connected to the first connecting member 7 by inserting the hook portions 31 provided at each end of the cross beam 3 into this hook hole 70c. .

In this embodiment, the first connecting piece 70 has a rectangular shape with a chamfered corner on the tip side (right side in the figure), as shown in FIG. 4(A). The shape of the connecting piece 70 is not particularly limited.

Continuing, as shown in FIGS. 2 and 5, the second connecting member 8 of the present embodiment is formed of upper and lower rectangular flat plates extending from the other end of the beam body 5 toward the opposite side of the beam body. A pair of second connecting pieces 80, 80 are provided. In addition, in this embodiment, the second connecting member 8 is integrally connected to the beam main body 5 by welding, but the method of attaching the second connecting member 8 to the beam main body 5 is not particularly limited. For example, the second connecting member 8 may be removably attached to the beam body 5 with bolts and nuts.

Further, as shown in FIGS. 2 and 5, each of the second connecting pieces 80 includes detents arranged side by side along the extension direction of the second connecting pieces 80 in order from the beam main body 5 side and facing each other in the vertical direction. A hole 80a and a fixing hole 80b are respectively formed.

Furthermore, the interval between the pair of second connecting pieces 80, 80 is set to a length that allows the pair of first connecting pieces 70, 70 to fit between the second connecting pieces 80, 80. In addition, when the pair of first connecting pieces 70, 70 are fitted between the second connecting pieces 80, 80, the detent hole 80a and the fixing hole 80b of the second connecting piece 80, respectively. It is provided at a position opposite to the rotation stopper hole 70b and the fixing hole 70a of 70.

Therefore, as shown in FIG. 6, the pair of first connecting pieces 70, 70 of the vertical beam 2 on one side (the left side in FIG. 6) in the depth direction of the suspended scaffolding device 1 are connected to the pair of first connecting pieces 70, 70 on the other side (the right side in FIG. 6). Fits between a pair of second connecting pieces 80, 80, stacks the first connecting piece 70 and second connecting piece 80 vertically, and connects to each opposing fixing hole 70a, 80b and each detent hole 70b, 80a. By inserting the pin P1 and the rotation stop pin P2, the two longitudinal beams 2, 2 can be connected in series.

In this embodiment, the pair of first connecting pieces 70, 70 are fitted between the pair of second connecting pieces 80, 80, but the distance between the pair of first connecting pieces 70, 70 is A pair of second connection pieces 80, 80 are set to a length that allows them to fit between one connection piece 70, 70, and a pair of second connection pieces 80, 80 are placed between a pair of first connection pieces 70, 70. They may be fitted together.

As described above, the coupling member J of the present embodiment includes the hanging material bracket 6 provided at one end of the beam main body 5, and the first connecting member 7 provided on the side of the hanging material bracket 6 opposite to the beam main body. The first connecting member 7 is provided with a fixing hole 70a and a detent hole 70b that can be connected to the second connecting members 8 of vertical beams 2 adjacent in the depth direction, and a hook hole 70c that can connect the horizontal beams 3. It is being

That is, in this embodiment, as shown in FIG. 2, a hanging material bracket 6 to which a chain C as a hanging material can be attached, and a first connecting member 7 capable of being connected to other longitudinal beams 2 and horizontal beams 3 are provided. , are arranged in series along the longitudinal direction of the longitudinal beam 2.

Therefore, compared to the conventional suspended scaffolding device in which the connecting member has the functions of connecting to the hanging member and connecting the vertical beam and the horizontal beam, the vertical beam 2 of this embodiment is connected to the chain C as the hanging member. Since the hanging material bracket 6 and the first connecting member 7 that connects the vertical beam 2 and the horizontal beam 3 are separated and provided in series, the width of the connecting member J is shortened.

Therefore, in this embodiment, even if the longitudinal beam 2 is provided with the connecting member J having the hanging material bracket 6 and the first connecting member 7, the width of the connecting member J in the vertical beam 2 is larger than that of other parts. Since it is not so wide compared to the width of the connecting member J, the connecting member J does not become bulky and is less likely to get in the way of storing or transporting the vertical beam 2.

Moreover, in this embodiment, as shown in FIG. Three intermediate beams 10 are spanned between the beam bodies 5, 5 of the longitudinal beams 2, 2 at predetermined intervals.

The configurations of the cross beam 3 and intermediate beam 10 will be described in detail below, but since the cross beam 3 and intermediate beam 10 of this embodiment have the same configuration, they will be described together. As shown in FIG. 7, the cross beam 3 and the intermediate beam 10 of this embodiment have a beam main body 30 (11) and a pin-shaped puller that protrudes downward from both longitudinal ends of the beam main body 30 (11), respectively. A hanging part 31 (12) is provided. Further, the beam main body 30 (11) is provided with a positioning piece 30a (11a) that stands up from the center in the width direction and extends along the longitudinal direction.

Then, by inserting the hook portions 31 provided at each end of the cross beam 3 into the hook holes 70c of the first connecting pieces 70 of the longitudinal beams 2, 2 adjacent to each other in the width direction, the cross beam 3 As shown in FIG. 1, it spans between the first connecting members 7, 7 of the vertical beams 2, 2 adjacent in the width direction.

Furthermore, by inserting the hook portions 12 provided at each end of the intermediate beam 10 into the hook holes 50d provided in each beam body 5 of the longitudinal beams 2, 2 adjacent in the width direction, the intermediate beam 10 is spanned between the beam bodies 5, 5 of the vertical beams 2, 2 adjacent in the width direction, as shown in FIG.

Further, in this embodiment, three intermediate beams 10 are bridged between the beam bodies 5, 5 of the vertical beams 2, 2 adjacent in the width direction, but the number of intermediate beams 10 is not particularly limited. .

The configurations of the cross beam 3 and intermediate beam 10 described above are merely examples, and are not limited to the configurations described above. ) may be used to bridge the longitudinal beams 2 adjacent to each other in the width direction. Moreover, although the cross beam 3 and the intermediate beam 10 may have different configurations, if they are configured the same as in this example, the types of parts that make up the suspended scaffolding device 1 can be reduced, so manufacturing costs can be reduced.

Next, the scaffolding board 4 that spans between the vertical beams 2, 2 adjacent in the width direction will be described in detail. The scaffold board 4 of this embodiment is made of a rectangular wooden board. The material of the scaffolding board 4 is not particularly limited as long as the necessary strength is ensured, but if the scaffolding board 4 is made of wood, it will be lightweight, making it easier to carry the scaffolding board 4 and making the installation work of the scaffolding board 4 easier. It becomes easier. Moreover, when the scaffolding board 4 is made of metal, it is preferable that the scaffolding board 4 is formed of a lightweight metal such as aluminum.

In this embodiment, the four scaffolding boards 4 are installed between the horizontal beams 3 and the intermediate beams 10 that are adjacent in the depth direction, and between the intermediate beams 10 and 10, as shown in FIG. has been done. At this time, each scaffold board 4 is placed on the flat plate part 50a of the beam body 5 of each longitudinal beam 2, the beam body 30 of the horizontal beam 3, and the beam body 11 of the intermediate beam 10, and is installed on each longitudinal beam 2. The outer periphery is surrounded by the positioning piece 50b provided on the cross beam 3 or the positioning piece 11a provided on the intermediate beam 10. Then, the horizontal movement of the scaffolding board 4 is regulated, so that the scaffolding board 4 is prevented from shifting in the horizontal direction.

Note that the number of scaffolding boards 4 installed between a pair of vertical beams 2, 2 adjacent in the width direction is not particularly limited, but the installation of scaffolding boards 4 between a pair of vertical beams 2, 2 adjacent in the width direction. As the number of scaffolding boards 4 increases, the area of each scaffolding board 4 becomes smaller, making it easier to carry the scaffolding board 4 and easier to install the scaffolding board 4. Furthermore, if the area of the scaffolding board 4 is small, the scaffolding board 4 will be less likely to bend when a worker stands on the scaffolding board 4, so the strength of the scaffolding board 4 will be improved. However, if the number of scaffold boards 4 to be installed between a pair of vertical beams 2, 2 adjacent to each other in the width direction is increased, the assembly process of the hanging scaffolding device 1 will increase accordingly, so the number of scaffold boards 4 to be installed is approximately 4. It is preferable that

Next, a method for assembling the suspended scaffolding device 1 of this embodiment will be described in detail using FIGS. 8 to 12. Hereinafter, the side where the floor area is expanded in the depth direction of the suspended scaffolding device 1 (lower side in FIG. 8) as viewed from the worker on the suspended scaffolding device 1 will be referred to as the back side, and the opposite side (the lower side in FIG. 8) will be referred to as the back side. The upper side) will be referred to as the front side.

First, a suspended scaffolding device 1 configured by connecting a plurality of scaffolding units A in the depth direction and the width direction is assembled on the ground. At this time, the front end of the vertical beam 2 located furthest to the front in the depth direction and the horizontal beam 3 spanned between the front ends of the vertical beam 2 are the front end of the vertical beam 2. are connected by a connecting member J connected to a second connecting member 8. The vertical beam 2 and the horizontal beam 3 located at the front end of the suspended scaffolding device 1 may be connected by a single connecting member J that is not connected to the beam main body 5.

Then, the upper end is attached to the building or structure on the hanging material bracket 6 provided on each scaffolding unit A (hereinafter referred to as "existing scaffolding unit A") of the suspended scaffolding device 1 assembled on the ground. By connecting the lower ends of the chains C and hoisting the chains C using heavy machinery or a chain hoist, the suspended scaffolding device 1 is suspended from a building or structure, as shown in FIG.

In this embodiment, the suspended scaffolding device 1 is composed of six existing scaffolding units A arranged in three rows in the width direction and two rows in the depth direction, as shown in FIG. The existing scaffolding units A share the longitudinal beam 2 with each other. Note that the number of existing scaffolding units A that constitute the suspended scaffolding device 1 may be appropriately determined as necessary, and it is sufficient that there is at least one. In addition, in FIGS. 8 to 12, the chain C is omitted in order to make it easier to understand the structure of the suspended scaffolding device 1.

Next, the vertical beam 2 on the back side is connected in series to the vertical beam 2 on the near side in the depth direction, which is the vertical beam 2 of the existing scaffolding unit A. In detail, first, as shown in FIG. 9(A), with the rear vertical beam 2 aligned in the width direction of the suspended scaffolding device 1, the second connecting member 8 of the rear vertical beam 2 is connected. The pair of first connecting pieces 70 of the first connecting member 7 of the vertical beam 2 on the front side are fitted between the pair of second connecting pieces 80, so that the fixing holes 70a and 80b are opposed to each other. In this state, when the connecting pin P1 is inserted into each of the opposing fixing holes 70a and 80b, the vertical beam 2 on the back side is aligned in the width direction of the suspended scaffolding device 1 and is oriented horizontally with respect to the vertical beam 2 on the near side. is rotatably connected to. At this time, a first guide cylinder 71 that communicates with each fixing hole 70a is bridged between the first connecting pieces 70, 70. Thereby, the insertion of the connecting pin P1 is guided by the first guide cylinder 71, so that the connecting pin P1 can be smoothly inserted into the fixing holes 70a and 80b.

Next, as shown in FIG. 9(B), using the connecting pin P1 as the rotation axis, horizontally rotate the rear vertical beam 2 to a position where it is in series with the front vertical beam 2, and then The detent hole 70b of the connecting piece 70 and the detent hole 80a of the second connecting piece 80 are opposed to each other. In this state, when the rotation stop pin P2 is inserted into the opposing rotation stop holes 70b and 80a, the rear vertical beam 2 is fixed to the front vertical beam 2 in a non-rotatable manner. At this time, a second guide tube 72 is bridged between the first connecting pieces 70, 70 and communicates with each of the detent holes 70b. Thereby, the insertion of the rotation stop pin P2 is guided by the second guide tube 72, so the rotation stop pin P2 can be smoothly inserted into the rotation stop holes 70b and 80a. At this time, although not explained in detail, protrusions (not shown) that come into contact with the upper surface of the second connecting piece 80 are provided at the base ends of the connecting pin P1 and the rotation stopper pin P2. The rotation stop pin P2 is prevented from coming off downward.

As described above, in this embodiment, the fixing holes 70a and 80b formed in the first connecting piece 70 of the first connecting member 7 and the second connecting piece 80 of the second connecting member 8, respectively, and the first connecting piece 70 and the connecting pin P1 inserted into the vertically opposing fixing holes 70a, 80b with the second connecting piece 80 stacked vertically, and the vertical beam on the near side among the vertical beams 2, 2 adjacent in the depth direction. A rotary connection device is configured to connect the second connection member 8 of the longitudinal beam 2 on the back side to the first connection member 7 of No. 2 so as to be rotatable in the horizontal direction. Further, detent holes 70b and 80a formed in the first connecting piece 70 of the first connecting member 7 and the second connecting piece 80 of the second connecting member 8, and the first connecting piece 70 and the second connecting piece 80 are provided. With the rotation stop pin P2 inserted into the rotation stop holes 70b and 80a facing each other in the vertically stacked state, the vertical beam 2 on the back side is arranged in series with the vertical beam 2 on the front side. A detent device is configured to non-rotatably fix the second connecting member 8 of the vertical beam 2 on the back side to the first connecting member 7 of the vertical beam 2 on the front side. Note that the fixing holes 70a, 80b and the detent holes 70b, 80a may be arranged at opposite positions.

Further, according to the above procedure, the vertical beam 2 on the back side can be connected to the vertical beam 2 on the front side in a state along the width direction of the suspended scaffolding device 1. Then, since both ends of the vertical beam 2 on the back side are located on the near side in the depth direction, the work of connecting the vertical beam 2 on the back side to the vertical beam 2 on the near side is performed on the already assembled scaffolding unit A. This can be done by two workers while holding the vertical beam 2. Therefore, the work of connecting the longitudinal beams 2, 2 adjacent to each other in the depth direction can be safely performed.

Further, a connecting member J including a first connecting member 7 is integrally attached to one end of the beam main body 5 of the longitudinal beam 2. Therefore, the step of connecting the coupling member J to the vertical beam 2 during the assembly work of the suspended scaffolding device 1 is not necessary, and therefore the workability is excellent.

Furthermore, in the existing scaffolding unit A, by repeating the above operation for the longitudinal beams 2 on the near side that are arranged parallel to each other in the width direction, as shown in FIG. are arranged parallel to each other.

Next, as shown in FIG. 11, hooks provided at both ends of the intermediate beam 10 are inserted into the hook holes 50d provided at the frontmost side of the beam bodies 5 of the longitudinal beams 2, 2 on the back side adjacent to each other in the width direction. 12, and then span the first intermediate beam 10 between the longitudinal beams 2 and 2 adjacent in the width direction, and then connect the first scaffolding board 4 to the horizontal beam of the existing scaffolding unit A. 3 and the first intermediate beam 10, and bridged between the longitudinal beams 2, 2.

Although not shown, the same procedure is followed for the second and third intermediate beams 10 and the second and third scaffolding boards 4. It bridges the gap between the two.

After that, as shown in FIG. 12, the hook part 31 of the cross beam 3 is inserted into the hook hole 70c provided in the first connecting member 7 of the longitudinal beams 2, 2 on the back side adjacent to each other in the width direction, and 3 between one end of the vertical beams 2 and 2 on the back side adjacent to each other in the width direction, and then the fourth scaffold board 4 is supported by the third intermediate beam 10 and the horizontal beam 3, and the depth is It spans between the vertical beams 2 and 2 on the back side which are adjacent in the direction.

Finally, although not shown, the floor area of the hanging scaffolding device 1 is expanded by attaching the lower end of the chain C, whose upper end is connected to the building or structure side, to the hanging material bracket 6 of the longitudinal beam 2 on the back side. can.

By repeating the above steps in the depth direction from any scaffolding unit A, the suspended scaffolding device 1 of this embodiment can expand the floor area to any position while suspended from a building or structure. It looks like this. However, the above-described method for assembling the suspended scaffolding device 1 is just an example, and the method is not limited to the above method as long as the suspended scaffolding device 1 can be assembled.

As described above, the suspended scaffolding device 1 of the present embodiment includes a plurality of vertical beams 2 that can be connected in series along the depth direction and are arranged in parallel in the width direction, and a plurality of vertical beams 2 that are adjacent to each other in the width direction. 2, and a scaffolding board 4 that spans between the longitudinal beams 2 and 2 adjacent in the width direction. A hanging material bracket 6 provided at one end to which a chain C as a hanging material for suspending the vertical beam 2 can be attached, a first connecting member 7 provided on the side opposite to the beam body of the hanging material bracket 6, and a beam main body 5 It has a second connecting member 8 which is provided at the other end and can be connected to the first connecting member 7 of the vertical beams 2 adjacent in the depth direction, and each end of the horizontal beam 3 is connected to the vertical beams 2 adjacent in the width direction. are connected to the first connecting member 7, respectively.

According to this configuration, the hanging material bracket 6 and the first connecting member 7 are arranged in series along the longitudinal direction of the vertical beam 2, so that the connecting member has the function of connecting to the hanging material and connecting the vertical beam and the horizontal beam. Compared to the conventional aggregated hanging scaffolding device, the width of the connecting member J having the hanging material bracket 6 and the first connecting member 7 can be made shorter.

Therefore, in this embodiment, even if the longitudinal beam 2 is provided with the connecting member J having the hanging material bracket 6 and the first connecting member 7, the width of the connecting member J of the vertical beam 2 is different from other parts. Since it is not so wide in comparison, the connecting member J does not become bulky, and the longitudinal beam 2 can be easily stored and transported.

In addition, as shown in the figure, the width of the hanging material bracket 6 of this embodiment is slightly wider than the width of the beam body 5, as shown in FIG. 3(A). The width of the hanging material bracket 6 may be set to be equal to or less than the width of the beam body 5 by making the fixing hole 63 into an I-shape along the axial direction of the vertical beam 2. In this way, the width of the connecting member J can be further reduced, so that the vertical beam 2 can be stored and transported more easily.

Further, in the suspended scaffolding device 1 of the present embodiment, among the vertical beams 2, 2 adjacent in the depth direction, the first connecting member 7 of the vertical beam 2 on the front side is connected to the second connecting member 7 of the vertical beam 2 on the back side. A rotary connection device that rotatably connects the connecting members 8 in the horizontal direction, and a second connection of the rear vertical beam 2 with the rear vertical beam 2 arranged in series with the front vertical beam 2. It is provided with a detent device that fixes the member 8 non-rotatably to the first connecting member 7 of the vertical beam 2 on the front side.

In the suspended scaffolding device 1 of the present embodiment, the first connecting member 7 has the first connecting piece 70 extending from the hanging material bracket 6 toward the side opposite to the beam main body, and the second connecting member 8 has the It has a second connecting piece 80 extending from the other end of the main body 5 along the axial direction of the beam main body 5, and the rotary connecting device has a fixing hole 70a formed in the first connecting piece 70 and the second connecting piece 80, respectively. 80b, and a connecting pin P1 that is inserted into the fixing holes 70a and 80b that face each other vertically with the first connecting piece 70 and the second connecting piece 80 stacked vertically, and the detent device Detent holes 70b and 80a formed in the piece 70 and second connection piece 80, respectively, and detent holes 70b and 80a that face each other vertically when the first connection piece 70 and the second connection piece 80 are stacked vertically. It has a rotation stop pin P2 to be inserted.

According to this configuration, when assembling the suspended scaffolding device 1, the vertical beam 2 on the back side can be rotatably connected to the vertical beam 2 on the near side while being aligned in the width direction of the suspended scaffolding device 1. Therefore, two workers can perform the work of connecting the back longitudinal beam 2 to the front longitudinal beam 2 while holding the back longitudinal beam 2. Therefore, the work of connecting the longitudinal beams 2, 2 adjacent to each other in the depth direction can be safely performed.

Furthermore, in the present embodiment, the rotation coupling device and the rotation prevention device include the first connection piece 70 and the second connection piece 80 having the fixing holes 70a, 80b and the rotation prevention holes 70b, 80a, the connection pin P1, and the rotation prevention device. Since it is sufficient to have only the pin P2, and the structure is simple, it becomes easy to connect the vertical beams 2, 2 that are adjacent in the depth direction.

However, in order to connect the longitudinal beams 2, 2 that are adjacent in the depth direction, the configuration of the rotation coupling device and the detent device is not essential, and the longitudinal beams 2, 2 that are adjacent in the depth direction are connected by other means. may be done.

Furthermore, in the present embodiment, the connecting pieces 70 and 80 constituting the first connecting member 7 and the second connecting member 8 are provided in upper and lower pairs, respectively, but the number of connecting pieces 70 and 80 is is not particularly limited, and for example, one first connecting piece 70 may be inserted between a pair of second connecting pieces 80, 80 so that the fixing holes 70a, 80b are vertically opposed to each other.

Furthermore, in this embodiment, the fixing holes 70a, 80b and the detent holes 70b, 80a are arranged side by side along the extending direction of each connecting piece 70, 80, but the fixing holes 70a, 80b and the detent hole 70b , 80a may be arranged side by side in the width direction of each connecting piece 70, 80. However, it is better to arrange the fixing holes 70a, 80b and the detent holes 70b, 80a side by side along the extension direction of each connecting piece 70, 80 than to arrange them side by side along the width direction. Since the width of the first connecting member 7 and the second connecting member 8 can be shortened, the width of the first connecting member 7 and the second connecting member 8 can be shortened. In this embodiment, the width of each connecting piece 70, 80 is set to be the same as the width of beam main body 5, but the width of each connecting piece 70, 80 is shorter than that of beam main body 5. It's okay.

In addition, the method for assembling the suspended scaffolding device 1 of this embodiment is to align the longitudinal beam 2 on the back side in the width direction, and to connect the fixing holes 70a and 80b of the vertical beam 2 on the near side and the vertical beam 2 on the back side. In the state where they are facing each other, the connecting pin P1 is inserted into the fixing holes 70a and 80b to connect the vertical beam 2 on the back side to the vertical beam 2 on the near side so as to be rotatable in the horizontal direction. Rotate the vertical beam 2 so that it is in series with the vertical beam 2 on the front side, and then insert the rotation stop pin P2 into the detent holes 70b and 80a of the vertical beam 2 on the front side and the vertical beam 2 on the back side. and fixing the rear longitudinal beam 2 to the front longitudinal beam 2 in a non-rotatable manner.

According to this configuration, the back side vertical beam 2 is horizontally rotatably connected to the front side vertical beam 2 with the back side vertical beam 2 aligned along the width direction of the suspended scaffolding device 1. Therefore, two workers can perform the work of connecting the back longitudinal beam 2 to the front longitudinal beam 2 while holding the back longitudinal beam 2. Therefore, the safety of the assembly work of the suspended scaffolding device 1 is improved.

Next, a suspended scaffolding device 100 according to a second embodiment will be described in detail. Here, the basic configuration of the suspended scaffolding device 100 of the second embodiment is the same as that of the suspended scaffolding device 1 of the first embodiment. Hereinafter, parts different from the suspended scaffolding device 1 of the first embodiment will be described in detail, and in order to avoid duplication of explanation, common components will be given the same reference numerals and detailed explanation will be omitted.

In the suspended scaffolding device 100 of the present embodiment, the structure of the vertical beam 200 and the rotary coupling device and detent device that connect the vertical beams 200, 200 adjacent to each other in the depth direction is different from that of the suspended scaffolding of the first embodiment. This is different from device 1.

It is inserted so that it can rotate freely in the direction. Further, first rotating pieces 702, 702 are connected to the upper end and lower end of the first shaft member S1, respectively, at a central position.

As a result, since the first rotating pieces 702, 702 are connected by the first shaft member S1, the first rotating pieces 702, 702 face each other vertically with the first shaft member S1 as the rotation axis. Since the pair of first rotating pieces 702, 702 can be rotated in the horizontal direction in synchronization, the posture of the pair of first rotating pieces 702, 702 can be changed between a vertical posture (the posture shown in FIG. 15A) with the long sides along the axial direction of the beam body 5 and It can be changed to a horizontal orientation (the orientation shown in FIG. 15(B)) in which the sides are orthogonal to the axial direction of the beam body 5.

It is inserted so that it can rotate freely in the direction. Further, second rotating pieces 802, 802 are connected to the upper end and lower end of the second shaft member S2 at the central position, respectively.

As a result, the second rotating pieces 802, 802 are connected by the second shaft member S2, so that the second rotating pieces 802, 802 face each other vertically with the second shaft member S2 as the rotation axis. Since the pair of second rotating pieces 802, 802 can be rotated in the horizontal direction in synchronization, the posture of the pair of second rotating pieces 802, 802 can be changed between a vertical posture (the posture shown in FIG. 15(C)) with the long sides along the axis direction of the beam body 5 and It can be changed to a horizontal orientation (the orientation shown in FIG. 15(D)) in which the sides are perpendicular to the axial direction of the beam body 5.

In addition, each rotating piece 702, 802 has a pair of connecting holes arranged across a center line passing through the widthwise center of the long side, as shown in FIGS. 14(B), 15(B), and (D). 702a, 702a (802a, 802a), and these connecting holes 702a, 802a are located closer to each other than each shaft member S1, S2, which is a rotating shaft, when each rotating piece 702, 802 is in a horizontal position.

It also includes a rectangular shape with chamfered corners.

Furthermore, in this embodiment, the interval between the pair of second rotating pieces 802, 802 is set to a length that allows the pair of first rotating pieces 702, 702 to fit between the pair of second rotating pieces 802, 802. has been done.

The housing groove 802b is formed in a size that can accommodate the first shaft member S1.

Therefore, as shown in FIGS. 16 and 17, when the two longitudinal beams 200, 200 are connected in series, the second shaft member S2 is rotatably inserted into the accommodation groove 702b of the first rotating piece 702. The holding cylinder 804 is housed therein, and the first shaft member S1 is housed in the housing groove 802b of the second rotating piece 802.

In this embodiment, the pair of first rotating pieces 702, 702 are fitted between the pair of second rotating pieces 802, 802, but the distance between the pair of first rotating pieces 702, 702 is The pair of second rotating pieces 802, 802 are set to a length that allows them to fit between the first rotating pieces 702, 702, and the pair of second rotating pieces 802, 802 are placed between the pair of first rotating pieces 702, 702. They may be fitted together.

Next, a method for assembling the suspended scaffolding device 100 according to the second embodiment will be explained. Since this method is the same as the method for assembling the suspended scaffolding device 1 of the embodiment, only the process of connecting vertical beams 200, 200 adjacent in the depth direction will be described in detail.

First, the first rotating piece 702 of the first connecting member 700 of the vertical beam 200 on the front side and the second rotating piece 802 of the second connecting member 800 of the vertical beam 200 on the back side are placed in a horizontal position via the regulating pin P3. Fix it to .

Next, as shown in FIG. 18(A), while aligning the vertical beam 200 on the back side in the width direction of the suspended scaffolding device 100, the beam main body formed on the first rotating piece 702 of the vertical beam 200 on the near side is aligned. A connecting hole 702a on the right side (left side in the figure) when viewed from the beam main body 5 side and a connecting hole 802a on the left side (upper side in the figure) when viewed from the beam main body 5 side formed in the second rotating piece 802 of the vertical beam 200 on the back side. With the two facing each other, the first connecting pin P4 is inserted into these connecting holes 702a and 802a to connect the back side vertical beam 200 to the front side vertical beam 200 so as to be freely rotatable in the horizontal direction.

Thereafter, as shown in FIG. 18(B), using the first connecting pin P4 as the rotation axis, horizontally rotate the longitudinal beam 200 on the back side to a position where it is in series with the longitudinal beam 200 on the near side. A connecting hole 702a on the left side (right side in the figure) formed in the first rotating piece 702 of the longitudinal beam 200 on the side as seen from the beam main body 5 side, and a connecting hole 702a formed on the second rotating piece 802 of the longitudinal beam 200 on the back side. The connecting holes 802a on the right side (right side in the figure) when viewed from the beam main body 5 side are opposed to each other. In this state, when the second connecting pin P5 is inserted into the opposing connecting holes 702a and 802a, the rear vertical beam 200 is fixed to the front vertical beam 200 in a non-rotatable manner.

In this embodiment, as shown in FIG. 18, the rear longitudinal beam 200 is folded to the left side in the figure of the front longitudinal beam 200, and then the longitudinal beam 200 on the near side is folded in series with the front longitudinal beam 200. The vertical beam 200 on the back side is horizontally rotated from the state where the longitudinal beam 200 on the near side is folded to the right in the figure to the position where it is in series with the vertical beam 200 on the near side. You can do it like this.

In that case, the left connecting hole 702a formed in the first rotating piece 702 when viewed from the beam body 5 side, and the right connecting hole 802a formed in the second rotating piece 802 when viewed from the beam body 5 side. By inserting the first connecting pin P4, the vertical beam 200 on the back side is connected to the vertical beam 200 on the near side so as to be rotatable in the horizontal direction, when viewed from the side of the beam main body 5 formed on the first rotating piece 702. Insert the second connecting pin P5 into the right connecting hole 702a and the right and left connecting holes 802a formed in the second rotating piece 802 when viewed from the beam main body 5 side, and connect the vertical beam 200 on the back side to the front side. What is necessary is just to fix it to the longitudinal beam 200 unrotatably.

As described above, in the present embodiment, the rotary coupling device is configured such that the first rotary piece 702 and the second rotary piece 802 in the sideways posture are stacked vertically, and one of the pair of vertically opposing connecting holes 702a and 802a is It is composed of a first connecting pin P4 inserted into one of the connecting holes 702a and 802a, and the detent device is configured such that the first rotating piece 702 and the second rotating piece 802 in a sideways posture are stacked vertically and rotated vertically. It is composed of a second connecting pin P5 inserted into the other connecting hole 702a, 802a of the pair of opposing connecting holes 702a, 802a.

Further, according to the above procedure, the rear vertical beam 200 can be horizontally rotatably connected to the front vertical beam 200 in a state along the width direction of the suspended scaffolding device 100. Then, since both ends of the vertical beam 200 on the back side are located on the near side in the depth direction, the work of connecting the vertical beam 200 on the back side to the vertical beam 200 on the near side is performed on the already assembled scaffolding unit A1. This can be carried out by two workers while holding the vertical beam 200. Therefore, the work of connecting the longitudinal beams 200, 200 adjacent to each other in the depth direction can be safely performed.

In addition, if each rotating piece 702, 802 is placed in a vertical position, even if the long side of each rotating piece 702, 802 is lengthened, the width of each rotating piece 702, 802 will be the length of the short side. Since the width of each rotating piece 702, 802 is shortened, each rotating piece 702, 802 does not interfere with storage or transportation of the vertical beam 200. Note that in this embodiment, the width of each protruding piece 701, 801 and the length of the short side of each rotating piece 702, 802 are set to be the same as the width of the beam main body 5; The widths of the rotating pieces 701 and 801 and the length of the short side of each rotating piece 702 and 802 may be shorter than the width of the beam body 5.
