Description

[Technical Field]

[0001] The present invention relates to a suspended scaffold. [Background technology]

[0002] In suspended scaffolding, a configuration is known in which a plurality of columnar support members extending horizontally and in directions intersecting each other are connected using scaffolding clamps. For example, Patent Document 1 discloses a suspended scaffolding in which a frame pipe extending in one horizontal direction and an auxiliary pipe extending in a direction intersecting the extension direction of the frame pipe are connected using scaffolding clamps. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2020-12322 Summary of the Invention [Problem to be solved by the invention]

[0004] As disclosed in Patent Document 1, in a configuration in which multiple columnar support members extending horizontally are connected with scaffolding clamps, the use of tools is required when assembling the suspended scaffolding, which makes the assembly process less efficient. Therefore, there is a demand for a configuration that allows for easy assembly of suspended scaffolding that is installed at high altitudes where workability is poor.

[0005] An object of the present invention is to provide a configuration in which multiple columnar support members extending horizontally can be easily connected in a suspended scaffolding to be installed at high altitudes where workability is poor. [Means for solving the problem]

[0006] A suspended scaffolding according to one embodiment of the present invention includes a plurality of horizontally extending support posts, a columnar support member whose longitudinal ends are connected to the support posts and which extends horizontally and in a direction intersecting the direction in which the support posts extend, and a plurality of scaffolding planks that are rectangular in plan view and supported by the support members so as to extend horizontally. The suspended scaffolding includes a columnar first connecting portion that connects the support posts to the support members. The support posts include a connected portion to which the longitudinal ends of the support members are connected by the first connecting portion. The connected portion has a first protruding portion that protrudes from a side surface of the support post in a direction intersecting the horizontally extending direction. The first protruding portion has a first connecting portion insertion hole that is parallel to the horizontal direction of the support posts and into which the first connecting portion can be inserted in the horizontal direction (first configuration).

[0007] In the above configuration, the support member can be connected to the support post by horizontally inserting the pillar-shaped first connecting member into the first connecting member insertion hole of the first protrusion of the connected portion of the support post. This makes it easy to connect support members to multiple support posts.

[0008] In the suspended scaffolding of the first configuration, the support member has a tubular portion at the longitudinal end portion thereof provided with a pair of through holes that penetrate in one direction, and the first connecting portion passes through the pair of through holes in the tubular portion and the first connecting portion insertion hole in the first protruding portion when the first protruding portion of the connected portion of the parent support is inserted into the tubular portion of the support member (second configuration).

[0009] This allows the parent support pole and the support member to be connected by passing the first connecting portion through the first connecting portion insertion hole of the first protrusion on the connected portion of the parent support pole and a pair of through holes in the tubular portion of the support member.

[0010] In the suspended scaffolding of the second configuration, the tubular portion of the support member has a slit at the bottom that extends from the end in the longitudinal direction of the support member in the longitudinal direction (third configuration).

[0011] This allows the tubular portion of the support member to be easily inserted from above into the first protruding portions of the connected portions of the multiple baby supports, making it easy to connect the support member to the multiple baby supports.

[0012] In the suspended scaffolding of the third configuration, the tubular portion of the support member has a fall prevention wall portion above the first protrusion portion that prevents the support member from falling when the first protrusion portion of the connected part of the parent support pole is inserted into the tubular portion (fourth configuration).

[0013] This prevents the tubular portion of the support member, into which the first protrusion of the connected portion of the baby post is inserted, from falling downward relative to the baby post, thereby preventing the support member from falling off the baby post.

[0014] The suspended scaffolding of the first configuration has a connection prevention portion behind the first connecting portion in the insertion direction of the first connecting portion that connects the upper support pole and the support member (fifth configuration).

[0015] The connection retaining portion can prevent the first connection portion from moving rearward in the insertion direction, and therefore can prevent the first connection portion from coming out of the first connection portion insertion hole of the baby support.

[0016] The suspended scaffolding of the fifth configuration has gap covering members arranged on the plurality of scaffolding boards so as to cover the gaps between the plurality of scaffolding boards, and the connecting retaining portion is provided on the lower part of the gap covering member (sixth configuration).

[0017] The gap covering member covers the spaces between multiple scaffolding boards, while the connection anti-slip portion prevents the first connection part from moving backward in the insertion direction.

[0018] In a suspended scaffolding of any one of the first to sixth configurations, each of the multiple scaffolding boards is arranged so that its longitudinal direction coincides with the longitudinal direction of the upper and lower support pole, and the connected portion has a second protruding portion that protrudes upward from the side of the upper and lower support pole, and the second protruding portion is located within the gap between the multiple scaffolding boards when viewed in the vertical direction of the multiple scaffolding boards (seventh configuration).

[0019] A wire for suspending the suspended scaffolding can be attached to the second protrusion located within the gap between the multiple scaffolding boards.

[0020] The seventh configuration of the suspended scaffolding has a gap covering member arranged on the scaffolding planks so as to cover the gaps between the scaffolding planks. The gap covering member has a support pole fixing part with a slit hole penetrating in the vertical direction at the bottom, and the second protrusion passes through the slit hole with the gap covering member covering the gaps between the scaffolding planks (eighth configuration).

[0021] This configuration allows the longitudinal position of the gap covering member to be determined relative to the baby post, and therefore the longitudinal position of the connecting retaining portion of the gap covering member to the first protrusion of the baby post can be determined relative to the longitudinal direction of the baby post.

[0022] The hanging scaffolding of the eighth configuration has a second connecting portion that connects the baby support pole and the gap covering member. The second protrusion has a second connecting portion insertion hole at a position parallel to the baby support pole in an upward direction, into which the second connecting portion can be inserted in the one direction. The baby support pole fixing portion has a through hole that passes through in the one direction. The second connecting portion is wedge-shaped and passes through the through hole of the baby support pole fixing portion and the second connecting portion insertion hole of the second protrusion when the second protrusion passes through the slit hole (ninth configuration).

[0023] The second connecting portion allows the radial position of the gap covering member relative to the baby support post to be positioned. Therefore, the connection retaining portion of the gap covering member can be positioned relative to the first connecting portion that connects the baby support post and the support member in the longitudinal and radial directions of the baby support post. Therefore, it is possible to prevent the first connecting portion from coming off the baby support post and the support member.

[0024] The first configuration of suspended scaffolding further includes a vertically extending support pole connecting member and a pillar-shaped third connecting portion connecting the support pole and the support pole connecting member. The plurality of support poles include a plurality of first support poles extending in the same direction and a plurality of second support poles extending in the same direction below the first support poles. The support members include a first support member whose longitudinal end is connected to the first support pole and a second support member whose longitudinal end is connected to the second support pole. The plurality of scaffolding planks include a plurality of first scaffolding planks supported by the first support member and a plurality of second scaffolding planks supported by the second support member. The connectable portion of the first support pole has a third protrusion that protrudes downward from the side of the first support pole and is connected to the longitudinal end of the support pole connecting member by the third connecting portion. The connectable portion of the second support pole has a second protrusion that protrudes upward from the side of the second support pole and is connected to the longitudinal end of the support pole connecting member by the third connecting portion. The upper end of the support pole connecting member is connected to the third protrusion and the lower end of the support pole connecting member is connected to the second protrusion, so that the second support member is positioned lower than the first support member. The plurality of second scaffolding boards are arranged to extend horizontally at a position lower than the plurality of first scaffolding boards (tenth configuration).

[0025] With this configuration, the multiple second scaffolding boards supported by the second support members can be positioned lower than the multiple first scaffolding boards supported by the first support members, thereby obtaining a suspended scaffolding in which the scaffolding boards are positioned at a height appropriate for the work environment in which the suspended scaffolding is installed.

[0026] The suspended scaffolding of the tenth configuration further includes a side wall member extending vertically between the first and second support posts and supported by the support post connecting member, and an external corner covering member covering the gap between the end of the plurality of first scaffolding boards on the first support post side and the upper end of the side wall member (eleventh configuration).

[0027] This allows the side wall member to cover the gap formed on the outer periphery of the second scaffolding board due to the step between the first scaffolding board and the second scaffolding board. The gap between the first scaffolding board and the side wall member can be covered with the corner covering member. Therefore, in a suspended scaffolding in which multiple scaffolding boards are arranged at different heights, it is possible to obtain a suspended scaffolding in which the gap formed by the step is covered.

[0028] In the suspended scaffolding of the 11th configuration, the protruding corner covering member has a connecting anti-slip portion at its lower part that is positioned rearward of the first connecting portion that connects the first parent support post and the first support member in the insertion direction of the first connecting portion, and rearward of the third connecting portion that connects the first parent support post and the parent support post connecting member in the insertion direction of the third connecting portion (12th configuration).

[0029] This makes it possible to obtain a suspended scaffolding in which the step is covered by the corner covering member, while the connection anti-slip portion prevents the first connection part from moving backward in the insertion direction.

[0030] In the suspended scaffolding of the 11th or 12th configuration, it further has an inside corner covering member that covers the gap between the end of the second scaffolding boards on the second support pole side and the lower end of the side wall member (13th configuration).

[0031] This allows the gap between the second scaffolding board and the side wall member to be covered with the inside corner covering member. Therefore, in a suspended scaffolding in which multiple scaffolding boards are arranged at different heights, it is possible to obtain a suspended scaffolding in which the gaps formed by the steps are covered.

[0032] In the suspended scaffolding of the first configuration, the first connecting portion is wedge-shaped (fourteenth configuration).

[0033] This allows the support member to be easily connected to the baby support pole without using a connecting tool such as a torque wrench. [Effects of the Invention]

[0034] A suspended scaffolding according to one embodiment of the present invention has a columnar first connecting part that connects a head support pole and a support member. The head support pole has a connected part to which a longitudinal end of the support member is connected by the first connecting part. The connected part has a first protruding part that protrudes horizontally from a side surface of the head support pole in a direction that intersects with the extension direction of the head support pole, and the first protruding part has a first connecting part insertion hole at a position parallel to the horizontal direction with respect to the head support pole, into which the first connecting part can be inserted in the horizontal direction.

[0035] This configuration allows the support members to be easily connected to multiple support posts. Therefore, it is possible to provide a configuration that allows multiple column-shaped support members extending horizontally to be easily connected in suspended scaffolding that is installed at high places where work is difficult.

[0037] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The same or corresponding parts in the drawings are designated by the same reference numerals, and their description will not be repeated. Furthermore, the dimensions of the components in each drawing do not faithfully represent the actual dimensions of the components, the dimensional ratios of the components, etc.

[0038] In the following description, the direction in which the scaffolding planks 4 extend is referred to as the horizontal direction, and the thickness direction of the scaffolding planks 4 is referred to as the up-down direction. The horizontal direction includes not only a direction horizontal to the ground, but also a direction tilted relative to the ground to the extent that the scaffolding 1 functions as a suspended scaffolding 1. The up-down direction is the vertical direction or a direction perpendicular to the horizontal direction. The direction in which the upper support poles 2 extend is referred to as the longitudinal direction of the suspended scaffolding 1. Within the longitudinal directions, the direction in which the connection retaining portion 62 is located relative to the connection portion of the upper support poles 2 and the support member 3 is referred to as "one side," and the opposite direction is referred to as "the other side." However, this definition is not intended to limit the orientation of the suspended scaffolding 1 when installed.

[0039] Furthermore, in the following description, the expressions "fix," "connect," and "attach" (hereinafter referred to as "fixing") include not only cases where members are directly fixed to each other, but also cases where members are fixed via other members. In other words, in the following description, the expression "fixing" includes both direct and indirect fixing of members to each other.

[0040] (Embodiment 1) A suspended scaffolding 1 according to this embodiment will be described with reference to Figures 1 to 9. The suspended scaffolding 1 is installed below a structure (not shown) by being suspended from the structure using hoisting equipment 8 such as wires and chains. The suspended scaffolding 1 is used in work environments where it is difficult to install scaffolding on the ground, such as when constructing a structure such as a bridge.

[0041] FIG. 1 is a perspective view showing the schematic configuration of a suspended scaffolding 1. FIG. 2 is a cross-sectional view taken along line II-II in FIG. 1. The suspended scaffolding 1 has a head support 2, a support member 3, a scaffolding board 4, a first connecting portion 5, a gap covering member 6, and a second connecting portion 7. As shown in FIG. 2, in this embodiment, the support member 3 is connected to the head support 2 by the first connecting portion 5. The scaffolding board 4 is fixed to the support member 3. The gap covering member 6 is connected to the head support 2 by the second connecting portion 7. A sling 8 is connected to the head support 2.

[0042] FIG. 3 is an enlarged view of the portion surrounded by dashed line A in FIG. 1. FIG. 4 is an enlarged view of the portion surrounded by dashed line B in FIG. 1. Note that in FIGS. 3 and 4, the scaffolding board 4 and a portion of the gap covering member 6 are shown by two-dot chain lines. Also, in FIG. 4, a portion of the gap covering member 6 has been removed for the sake of explanation. In FIG. 3, the member designated by the reference numeral 62 is a portion of the gap covering member 6 that is provided below the gap covering member 6. In FIG. 4, the member designated by the reference numeral 63 is a portion of the gap covering member 6 that is provided below the gap covering member 6.

[0043] As shown in Figures 3 and 4, the pole 2 is a columnar member extending in one horizontal direction. The suspended scaffolding 1 has multiple poles 2. The multiple poles 2 extend in the same direction at the same height of the suspended scaffolding 1. Each pole 2 has multiple flange portions 21 provided at predetermined intervals in the longitudinal direction. The flange portions 21 are, for example, welded to the side of the pole 2. The flange portions 21 may be formed integrally with the pole 2. The flange portions 21 are the connected portions of the present invention.

[0044] 5 and 6, the flange portion 21 is a flange-shaped member extending in the radial direction of the baby support post 2. In detail, the flange portion 21 has protrusions protruding in four radial directions from the side surface of the baby support post 2. In this embodiment, the flange portion 21 has a pair of first protrusions 22 protruding in a direction that intersects with the horizontal direction relative to the baby support post 2, a second protrusion 23 protruding upward, and a third protrusion 24 protruding downward.

[0045] The first protrusion 22 has a first connecting portion insertion hole 22a that penetrates the baby support post 2 in the longitudinal direction at a position horizontally parallel to the baby support post 2. The first protrusion 22 can be inserted into a tubular portion 32 of the support member 3, which will be described later.

[0046] The second protrusion 23 has a second connecting part insertion hole 23a that penetrates the baby support pole 2 in the longitudinal direction at a position parallel to the upward direction of the baby support pole 2. The second protrusion 23 can be inserted into a slit hole 64a in the baby support pole fixing part main body 64 of the baby support pole fixing part 63 (described later) in the gap covering member 6. In addition, as shown in FIG. 2, a suspender 8 that suspends the suspended scaffolding 1 can be connected to the second protrusion 23.

[0047] The third protrusion 24 has a third connecting portion insertion hole 24a that penetrates the baby support post 2 in the longitudinal direction at a position parallel to the downward direction of the baby support post 2.

[0048] 5 to 8, the support member 3 is a columnar member that extends horizontally and in a direction that intersects with the extension direction of the baby support pole 2. The support member 3 has a columnar support member main body 31 and a cylindrical tubular portion 32 connected to the longitudinal end of the support member main body 31. The first protrusion 22 of the flange portion 21 of the baby support pole 2 is inserted into the tubular portion 32.

[0049] 7 and 8, the tubular portion 32 is provided with a pair of through-holes 33 that penetrate the tubular portion 32 horizontally and in the longitudinal direction of the baby support post 2. As described above, the first protrusion 22 has a first connecting portion insertion hole 22a that penetrates the tubular portion 32 horizontally and in the longitudinal direction of the baby support post 2. Therefore, when the first protrusion 22 is inserted into the tubular portion 32, the first connecting portion 5 can penetrate the pair of through-holes 33 of the tubular portion 32 and the first connecting portion insertion hole 22a of the first protrusion 22 horizontally and in the longitudinal direction of the baby support post 2.

[0050] The tubular portion 32 has a slit 34 at its bottom that extends from the longitudinal end in the longitudinal direction of the support member 3. The length of the slit 34 is longer than the length from the side surface of the upper support pole 2 to the tip of the first protrusion 22. This allows the tubular portion 32 of the support member 3 to be inserted into the first protrusion 22 from above when assembling the suspended scaffolding 1. In other words, the slit 34 makes it easy to position the support member 3 on the upper support pole 2.

[0051] The tubular portion 32 does not have a slit at the top. When the first protrusion 22 is inserted into the tubular portion 32, an upper wall portion 35 formed by the upper portion of the tubular portion 32 is located above the first protrusion 22. This prevents the support member 3 from falling downward from the parent support pole 2. Therefore, the support member 3 can be prevented from falling off the parent support pole 2. In other words, the upper wall portion 35 of the tubular portion 32 functions as a fall prevention wall that prevents the support member 3 of the present invention from falling off.

[0052] As shown in FIG. 1, the scaffolding board 4 is a member having a rectangular shape in a plan view. The scaffolding board 4 is spanned across a plurality of support members 3. That is, the scaffolding board 4 is supported by the support members 3 so that it extends horizontally and its longitudinal direction coincides with the longitudinal direction of the support posts 2. The scaffolding board 4 is fixed to the support members 3 by fastening members (not shown). Note that the longitudinal direction of the scaffolding board 4 and the longitudinal direction of the support posts 2 do not have to coincide completely. The plurality of scaffolding boards 4 form the floor of the workplace on which workers work.

[0053] The suspended scaffolding 1 has a plurality of scaffolding boards 4. The scaffolding boards 4 are arranged to extend horizontally at the same height of the suspended scaffolding 1. As shown in Figures 5 and 6, the scaffolding boards 4 are arranged so that there is a gap between adjacent scaffolding boards 4. When the scaffolding boards 4 are viewed from above, the upper support post 2 is located in the gap. The second protrusion 23 on the flange portion 21 of the upper support post 2 protrudes upward between adjacent scaffolding boards 4.

[0054] 3, 7, and 8, in this embodiment, the first connecting portion 5 is a wedge-shaped member whose width decreases from one longitudinal end to the other. That is, the first connecting portion 5 is a columnar member, not a fastening member with threads like a bolt. Note that a wedge-shaped member is generally a member that is inserted and fixed into a hole or the like by being struck with a hammer or the like, but in the present invention, the wedge-shaped member also includes a member that can be inserted and fixed into the hole or the like without using a tool.

[0055] The first connecting portion 5 passes horizontally through a pair of through holes 33 in the tubular portion 32 of the support member 3 and a first connecting portion insertion hole 22a in the first protrusion 22 in the flange portion 21 of the supporting post 2. This connects the supporting post 2 and the support member 3. The first connecting portion 5 is inserted into the pair of through holes 33 and the first connecting portion insertion hole 22a from one longitudinal direction of the suspended scaffolding 1. Hereinafter, the end of the first connecting portion 5 that is inserted last into the pair of through holes 33 and the first connecting portion insertion hole 22a in the longitudinal direction of the suspended scaffolding 1 will be referred to as the rear portion in the insertion direction of the first connecting portion 5, and the end that is inserted first will be referred to as the front portion. Also, below, in the suspended scaffolding 1, the direction in which the rear portion of the first connecting portion 5 is positioned relative to the front portion when inserting the first connecting portion 5 into the pair of through holes 33 and the first connecting portion insertion hole 22a will be referred to as the rear portion in the insertion direction of the first connecting portion 5.

[0056] 7 and 8, in this embodiment, the first connecting portion 5 has a first stopper 51 at its rear that is taller than the other portions. The first connecting portion 5 has a second stopper 52 at its front that is taller than the other portions. The first stopper 51 and the second stopper 52 are located outside the tubular portion 32, with the first connecting portion 5 passing through a pair of through-holes 33 in the tubular portion 32 of the support member 3 and the first connecting portion insertion hole 22a in the first protrusion 22 in the flange portion 21 of the baby support pole 2.

[0057] The vertical dimension of the first stopper 51 is larger than the vertical dimension of the through hole 33 that is located on one side of the suspended scaffolding 1 in the longitudinal direction. This prevents the rear of the first connecting part 5 from passing through the through hole located on one side of the longitudinal direction. In other words, the first connecting part 5 does not slip out to the other side of the suspended scaffolding 1 in the longitudinal direction.

[0058] The vertical dimension of the second stopper 52 is smaller than the vertical dimension of the through hole 33 of the pair that is located on the other longitudinal side of the suspended scaffolding 1. This allows the front part of the first connecting part 5 to pass through the through hole located on the other longitudinal side. The vertical dimension of the second stopper 52 is larger than the vertical dimension of the through hole 33 of the pair that is located on one longitudinal side. This prevents the front part of the first connecting part 5 from passing through the through hole located on one longitudinal side. In other words, the first connecting part 5 does not slip out to one longitudinal side of the suspended scaffolding 1. In other words, in this embodiment, the first connecting part 5 is configured not to slip out of the tubular part 32.

[0059] In the longitudinal direction of the suspended scaffolding 1, a connection stopper portion 62 of the gap covering member 6, which will be described later, is located behind the first connecting portion 5. The connection stopper portion 62 restricts the first connecting portion 5 from moving in one direction in the longitudinal direction. In other words, when the first connecting portion 5 is inserted into the tubular portion 32, it will not slip out in one direction in the longitudinal direction of the suspended scaffolding 1.

[0060] As described above, the upper wall portion 35 of the tubular portion 32 of the support member 3 is located above the first protrusion 22 into which the first connecting portion 5 is inserted. Therefore, even if the first connecting portion 5 comes off the tubular portion 32, the support member 3 can be prevented from falling downward.

[0061] In this way, with the suspended scaffolding 1, the support member 3 can be connected to the upper support pole 2 simply by passing the first connecting part 5 through the first protruding part 22 and the tubular part 32. In other words, with the suspended scaffolding 1, there is no need to use a connecting tool such as a torque wrench to connect the upper support pole 2 and the support member 3.

[0062] 5 and 6, the gap covering member 6 is placed on a plurality of scaffolding boards 4 so as to cover the gaps between the scaffolding boards 4. Fig. 9 is a view of a portion of the gap covering member 6 separated from the scaffolding boards 4 as viewed from below. The gap covering member 6 has a covering body 61, and a connecting stopper part 62 and a parent support fixing part 63 connected to the underside of the covering body 61.

[0063] The covering body 61 is a flat plate-shaped member. As shown in Figures 1, 5 and 6, the covering body 61 is placed on the upper surface of the scaffolding board 4 so as to cover the gap between adjacent scaffolding boards 4. As shown in Figure 2, when the covering body 61 is placed on the upper surface of the scaffolding board 4, the connecting anti-slip portion 62 and the parent support fixing portion 63 extend downward between the adjacent scaffolding boards 4.

[0064] The covering body 61 has a suspender mounting hole 61a and an opening / closing portion 61b. The suspender mounting hole 61a penetrates the covering body 61 in the thickness direction. When the covering body 61 is placed on the top surface of the scaffolding board 4 and the scaffolding board 4 is viewed in the vertical direction, the suspender mounting hole 61a coincides with the position of the second protrusion 23 on the flange portion 21 of the support pole 2. The suspender 8 connected to the second protrusion 23 passes through the suspender mounting hole 61a and is connected to the structure from which the suspended scaffolding 1 is suspended. In other words, the suspender mounting hole 61a prevents interference between the gap covering member 6 and the second protrusion 23 to which the suspender 8 is connected.

[0065] The opening / closing part 61b is a door. The opening / closing part 61b is located above the parent / child support post fixing part 63. By opening the opening / closing part 61b, the inside of the parent / child support post fixing part 63 can be seen. The opening / closing part 61b is opened, for example, when removing the second connecting part 7 described below. In other words, the opening / closing part 61b makes it easy to remove the second connecting part 7. The covering part main body does not have to have an opening / closing part.

[0066] 2 and 9, the connection retaining portion 62 extends downward from the underside of the covering body 61. The lower end of the connection retaining portion 62 is located rearward in the insertion direction of the first connecting portion 5 when the covering body 61 is placed on the top surface of the scaffolding board 4. The connection retaining portion 62 restricts movement of the first connecting portion 5 in one longitudinal direction. In other words, by placing the gap covering member 6 on the scaffolding board 4, the first connecting portion 5 is prevented from slipping out from the connection portion between the parent support 2 and the support member 3.

[0067] The parent support fixing part 63 is connected to the underside of the covering part main body 61. The parent support fixing part 63 determines the position of the gap covering member 6 relative to the parent support 2. The parent support fixing part 63 has a parent support fixing part main body 64 and an intermediate wall 65. The parent support fixing part main body 64 is a member with a U-shaped cross section and extends in the longitudinal direction of the parent support 2. The open end of the parent support fixing part main body 64 is connected to the underside of the covering part main body 61 when viewed in the longitudinal direction of the parent support 2 with the covering part main body 61 placed on the top surface of the scaffolding board 4. This forms a space S between the parent support fixing part main body 64 and the covering part main body 61.

[0068] 4 and 9, the intermediate wall 65 is disposed so that the longitudinal direction corresponds to the thickness direction within the space S surrounded by the parent support post fixing part main body 64 and the covering part main body 61. The intermediate wall 65 has a through-hole 65a penetrating in the thickness direction.

[0069] As shown in Figures 6 and 9, the main body 64 of the ladder support fixing part has a slit 64a that penetrates vertically through its bottom surface. The slit 64a is located on the other side of the intermediate wall 65 in the longitudinal direction of the suspended scaffolding 1. When the gap covering member 6 is arranged on the scaffolding boards 4 so as to cover the gaps between the scaffolding boards 4, the second protrusion 23 penetrates the slit 64a. That is, the tip of the second protrusion 23 is located on the other side of the intermediate wall 65 in the longitudinal direction within the space S. With the second protrusion 23 penetrating the main body 64 of the ladder support fixing part, the second connecting part 7 can be inserted through the through-hole 65a of the intermediate wall 65 and the second connecting part insertion hole 23a of the second protrusion 23.

[0070] 2 and 4, the second connecting part 7 is a wedge-shaped member. The second connecting part 7 passes horizontally through the through-hole 65a in the intermediate wall 65 of the parent-post fixing part 63 and the second connecting part insertion hole 23a of the second protrusion 23. This connects the parent-post 2 and the gap covering member 6. The second connecting part 7 is inserted into the through-hole 65a and the second connecting part insertion hole 23a from one longitudinal side of the suspended scaffolding 1.

[0071] (Method for connecting parent support posts, support members, and gap covering members) Next, a method for connecting the baby support pole 2, the support member 3, and the gap covering member 6 will be described with reference to FIGS. 2 and 10 to 13. FIG.

[0072] As shown in Figure 10, the first protrusion 22 of the flange 21 of the baby support pole 2 is inserted into the tubular portion 32 of the support member 3. The tubular portion 32 has a slit 34 at its bottom, through which the first protrusion 22 can pass. Therefore, the tubular portion 32 can be easily inserted into the first protrusion 22 from above. The tubular portion 32 also has an upper wall 35 at its top. This prevents the support member 3 from falling out of the baby support pole 2.

[0073] 11, with the first protrusion 22 inserted into the tubular portion 32 of the support member 3, the first connecting portion 5 is inserted into the pair of through holes 33 and the first connecting portion insertion hole 22a from one longitudinal side of the suspended scaffolding 1. This connects the support member 3 to the upper support 2.

[0074] After connecting the support member 3 to the parent support 2, multiple scaffolding boards 4 are fixed to the support member 3. Then, gap covering members 6 are placed on the multiple scaffolding boards 4 so as to cover the gaps between the multiple scaffolding boards 4. By placing the gap covering members 6 on the multiple scaffolding boards 4, the connection slip-out prevention portion 62 is positioned behind the first connecting portion 5.

[0075] 12, when placing the gap covering member 6 on multiple scaffolding boards 4, the second protrusion 23 of the baby support 2 is inserted into the slit hole 64a of the baby support fixing part 63. This positions the gap covering member 6 relative to the baby support 2 in the longitudinal direction.

[0076] 13, with the second protrusion 23 of the baby post 2 inserted into the baby post fixing part 63, the second connecting part 7 is inserted into the through-hole 65a and the second connecting part insertion hole 23a in the intermediate wall 65 of the baby post fixing part 63. This connects the baby post 2 and the gap covering member 6, and determines the radial position of the gap covering member 6 relative to the baby post 2. In other words, the longitudinal and radial positions of the gap covering member 6 relative to the baby post 2 are determined.

[0077] By positioning the gap covering member 6 in the longitudinal direction and the radial direction relative to the parent support post 2, the longitudinal direction and the radial direction of the connection retaining portion 62 are positioned relative to the first connecting portion 5. In other words, the connection retaining portion 62 is fixed to the rear of the first connecting portion 5 in the insertion direction. This makes it possible to prevent the first connecting portion 5 from falling off the parent support post 2 and the support member 3.

[0078] In this embodiment, the configuration of the suspended scaffolding 1 has been described in which the first connecting parts 5 are inserted into the pair of through holes 33 and the first connecting part insertion holes 22a from one side in the longitudinal direction of the suspended scaffolding 1. However, the suspended scaffolding may also be configured in such a way that the first connecting parts are inserted from the other side in the longitudinal direction of the suspended scaffolding. The suspended scaffolding may also be configured in such a way that some first connecting parts are inserted from one side in the longitudinal direction of the suspended scaffolding and other first connecting parts are inserted from the other side in the longitudinal direction of the suspended scaffolding. In this case, the suspended scaffolding only needs to be configured in such a way that the connection stopper parts are positioned rearward in the insertion direction of the first connecting parts.

[0079] As explained above, in the suspended scaffolding 1 according to this embodiment, the parent support 2 and the support member 3 are connected by a pillar-shaped first connecting portion 5. The parent support 2 has a flange portion 21 to which the longitudinal end of the support member 3 is connected by the first connecting portion 5. The flange portion 21 has a first protruding portion 22 that protrudes from the side of the parent support 2 in a horizontal direction that intersects with one direction in which the parent support 2 extends. The first protruding portion 22 has a first connecting portion insertion hole 22a, at a position parallel to the parent support 2 in the horizontal direction, into which the first connecting portion 5 can be inserted in the one direction.

[0080] In this configuration, the parent support pole 2 and the support member 3 can be connected by inserting the first connecting part 5 in one direction into the first connecting part insertion hole 22a of the first protrusion 22 on the flange part 21 of the parent support pole 2. This makes it possible to easily connect the support member 3 to multiple parent supports 2. Therefore, in a suspended scaffolding 1 installed at a high place where workability is poor, it is possible to provide a configuration that allows multiple columnar members extending horizontally to be easily connected.

[0081] The support member 3 has a tubular portion 32 at its longitudinal end portion, which is provided with a pair of through holes 33 that penetrate horizontally and in the one direction. When the first protrusion 22 of the flange 21 of the baby support pole 2 is inserted into the tubular portion 32 of the support member 3, the first connecting portion 5 penetrates through the pair of through holes 33 of the tubular portion 32 and the first connecting portion insertion hole 22a of the first protrusion 22.

[0082] This allows the baby support post 2 and the support member 3 to be connected by passing the first connecting portion 5 through the first connecting portion insertion hole 22a of the first protrusion 22 in the flange portion 21 of the baby support post 2 and a pair of through holes 33 in the tubular portion 32 of the support member 3.

[0083] Furthermore, the suspended scaffolding 1 has a connection stopper 62 behind the first connecting part 5, which connects the upper support 2 and the support member 3, in the insertion direction of the first connecting part 5. In this embodiment, the connection stopper 62 is provided on the lower part of the gap covering member 6 arranged on the multiple scaffolding boards 4.

[0084] The gap covering member 6 has a baby post fixing part 63 at its bottom. A slit hole 64a is provided in the baby post fixing part 63, which penetrates in the vertical direction. The second protrusion 23 of the flange part 21 of the baby post 2 passes through the slit hole 64a. The second protrusion 23 and the baby post fixing part 63 are connected by a wedge-shaped second connecting part 7.

[0085] This configuration determines the longitudinal and radial positions of the gap covering member 6 relative to the parent support post 2. Therefore, the connection retaining portion 62 of the gap covering member 6 is fixed in the longitudinal and radial directions to the first connecting portion 5 that connects the parent support post 2 and the support member 3. This prevents the first connecting portion 5 from coming off the parent support post 2 and the support member 3. Therefore, it is possible to provide a configuration that allows multiple column-shaped support members extending horizontally to be easily and reliably connected in a suspended scaffolding 1 that is installed at a high place where workability is poor.

[0086] (Embodiment 2) Next, a suspended scaffolding 100 according to a second embodiment will be described with reference to Figures 14 to 18. In the suspended scaffolding 100 according to this embodiment, a plurality of scaffolding planks are arranged to extend horizontally at a plurality of different heights on the suspended scaffolding 100. Below, the same components as those in the first embodiment are given the same reference numerals and their description will be omitted, and only the components that differ from the first embodiment will be described.

[0087] 14 is a perspective view showing the schematic configuration of the suspended scaffolding 100. The suspended scaffolding 100 has a plurality of scaffolding units 101, 201, a front support connecting member 303, a side wall member 304, a third connecting portion 305, an external corner covering member 306, and an internal corner covering member 316.

[0088] A first scaffolding unit 101 of the multiple scaffolding units 101, 201 has a first parent support 102, a first support member 103, a first scaffolding board 104, and a first connecting portion 5. The first parent support 102 is a parent support of the present invention. The first support member 103 is a support member of the present invention. The first scaffolding board 104 is a scaffolding board of the present invention.

[0089] The first parent support 102, the first support member 103, and the first scaffolding plank 104 have the same configuration as the parent support 2, the support member 3, and the scaffolding plank 4 of embodiment 1, respectively. The first parent support 102 and the first support member 103 are connected by a first connecting part 5, similar to the parent support 2 and the support member 3 of embodiment 1. The first scaffolding plank 104 is supported by the first support member 103, similar to the support member 3 for the scaffolding plank 4 of embodiment 1. Therefore, a description of the configuration of the first parent support 102, the first support member 103, and the first scaffolding plank 104 will be omitted.

[0090] The second scaffolding unit 201, which is the other of the multiple scaffolding units 101, 201, has a second parent support 202, a second support member 203, a second scaffolding board 204, and a first connecting portion 5. The second parent support 202 is the parent support of the present invention. The second support member 203 is the support member of the present invention. The second scaffolding board 204 is the scaffolding board of the present invention.

[0091] The second baby support 202, the second support member 203, and the second scaffolding plank 204 have the same configurations as the baby support 2, the support member 3, and the scaffolding plank 4 of embodiment 1, respectively. The second baby support 202 and the second support member 203 are connected by a first connecting part 5, similar to the baby support 2 and the support member 3 of embodiment 1. The second scaffolding plank 204 is supported by the second support member 203, similar to the support member 3 for the scaffolding plank 4 of embodiment 1. Therefore, a description of the configurations of the second baby support 202, the second support member 203, and the second scaffolding plank 204 will be omitted.

[0092] As shown in Figure 14, the multiple first support posts 102 of the first scaffolding unit 101 extend in one horizontal direction at a predetermined height position of the suspended scaffolding 100. The multiple second support posts 202 of the second scaffolding unit 201 extend in the same direction below the first support posts 102. The multiple first support posts 102 and the multiple second support posts 202 partially overlap when viewed in the vertical direction. The first support posts 102 of the first scaffolding unit 101 and the second support posts 202 of the second scaffolding unit 201 that overlap in the vertical direction are connected in the vertical direction by a support post connecting member 303, which will be described later. In the following, for the sake of explanation, the state in which the first parent support 102 of the first scaffolding unit 101 and the second parent support 202 of the second scaffolding unit 201 are connected by the parent support connecting member 303 will also be referred to as the first scaffolding unit 101 and the second scaffolding unit 201 being connected by the parent support connecting member 303.

[0093] Figure 15 is an enlarged view of the portion surrounded by the dashed-dotted line C in Figure 14. Figure 16 is a cross-sectional view taken along line XVI-XVI in Figure 15. In Figure 15, the first scaffolding plank 104, the second scaffolding plank 204, and the side wall member 304 are indicated by dashed-two-dot lines. Also, in Figure 16, some components are omitted for ease of explanation.

[0094] 15 and 16, the first baby support post 102 and the second baby support post 202 have flange portions 21 similar to those in embodiment 1. That is, as shown in Fig. 16, the flange portion 21 of the first baby support post 102 has a pair of first protrusions 22 protruding in a direction intersecting the one horizontal direction, a second protrusion 23 protruding upward, and a third protrusion 24 protruding downward. The flange portion 21 of the second baby support post 202 has a pair of first protrusions 22 protruding in a direction intersecting the one horizontal direction, a second protrusion 23 protruding upward, and a third protrusion 24 protruding downward.

[0095] As in the first embodiment, the first protrusion 22 on the flange 21 of the first baby post 102 has a first connecting part insertion hole 22a that penetrates the first baby post 102 in the longitudinal direction at a position parallel to the horizontal direction of the first baby post 102. The second protrusion 23 has a second connecting part insertion hole 23a that penetrates the first baby post 102 in the longitudinal direction at a position parallel to the upward direction of the first baby post 102. The third protrusion 24 has a third connecting part insertion hole 24a that penetrates the first baby post 102 in the longitudinal direction at a position parallel to the downward direction of the first baby post 102. The second protrusion 23 can be inserted into a tubular part 332a (described later) of the baby post connecting member 303.

[0096] As in the first embodiment, the first protrusion 22 on the flange 21 of the second baby post 202 has a first connecting part insertion hole 22a that penetrates the second baby post 202 in the longitudinal direction at a position parallel to the horizontal direction of the second baby post 202. The second protrusion 23 has a second connecting part insertion hole 23a that penetrates the second baby post 202 in the longitudinal direction at a position parallel to the upward direction of the second baby post 202. The third protrusion 24 has a third connecting part insertion hole 24a that penetrates the second baby post 202 in the longitudinal direction at a position parallel to the downward direction of the second baby post 202. The third protrusion 24 can be inserted into a tubular portion 332b (described later) of the baby post connecting member 303.

[0097] The baby support post connecting member 303 is a column-shaped member extending vertically. The baby support post connecting member 303 vertically connects the first baby support post 102 and the second baby support post 202, which are aligned vertically. Specifically, as shown in FIGS. 15 and 16 , the baby support post connecting member 303 has a baby support post connecting member main body 331 extending vertically, a cylindrical tubular portion 332a connected to the upper end of the baby support post connecting member main body 331, and a cylindrical tubular portion 332b connected to the lower end of the baby support post connecting member main body 331. The third protrusion 24 of the flange portion 21 of the first baby support post 102 is inserted into the cylindrical portion 332a. The second protrusion 23 of the flange portion 21 of the second baby support post 202 is inserted into the cylindrical portion 332b.

[0098] The tubular portion 332a is provided with a pair of through-holes 333a that penetrate the tubular portion 332a horizontally and in the longitudinal direction of the first parent support 102. As described above, the third protrusion 24 has a third connecting portion insertion hole 24a that penetrates horizontally. Therefore, when the third protrusion 24 is inserted into the tubular portion 332a, the third connecting portion 305 can penetrate the pair of through-holes 333a of the tubular portion 332a and the third connecting portion insertion hole 24a of the third protrusion 24 horizontally and in the longitudinal direction of the first parent support 102.

[0099] 16, the tubular portion 332a has a slit 334a extending downward from the upper end. The length of the slit 334a is longer than the length from the side surface of the first support pole 102 to the tip of the third protrusion 24. This makes it possible to insert the third protrusion 24 into the tubular portion 332a while moving the support pole connecting member 303 horizontally when assembling the suspended scaffolding 100. In other words, the slit 334a makes it easy to position the support pole connecting member 303 relative to the first support pole 102.

[0100] The cylindrical portion 332b is provided with a pair of through holes 333b that penetrate the cylindrical portion 332b horizontally and in the longitudinal direction of the second parent support 202. As described above, the second protrusion 23 has a second connecting portion insertion hole 23a that penetrates horizontally. Therefore, when the second protrusion 23 is inserted into the cylindrical portion 332b, the third connecting portion 305 can penetrate the pair of through holes 333b of the cylindrical portion 332b and the second connecting portion insertion hole 23a of the second protrusion 23 horizontally and in the longitudinal direction of the second parent support 202.

[0101] The cylindrical portion 332b has a slit 334b ​​extending upward from the lower end. The length of the slit 334b ​​is longer than the length from the side surface of the second parent pole 202 to the tip of the second protrusion 23. This makes it possible to insert the second protrusion 23 into the cylindrical portion 332b while moving the parent pole connecting member 303 horizontally when assembling the suspended scaffolding 100. In other words, the slit 334b ​​makes it easy to position the parent pole connecting member 303 relative to the second parent pole 202.

[0102] In this embodiment, the first baby support post 102 and the baby support post connecting member 303 are connected by a third connecting portion 305. In detail, as shown in Fig. 16, the third connecting portion 305 passes horizontally through a pair of through-holes 333a in the tubular portion 332a of the baby support post connecting member 303 and the third connecting portion insertion hole 24a of the third protrusion 24 in the flange portion 21 of the first baby support post 102.

[0103] 16 , the second baby support post 202 and the baby support post connecting member 303 are connected by a third connecting portion 305. In detail, as shown in FIG. 16 , the third connecting portion 305 passes horizontally through a pair of through-holes 333b in the tubular portion 332b of the baby support post connecting member 303 and the second connecting portion insertion hole 23a in the second protrusion 23 in the flange portion 21 of the second baby support post 202.

[0104] The configuration of the third connecting portion 305 is the same as that of the first connecting portion 5. Therefore, a description of the configuration of the third connecting portion 305 will be omitted.

[0105] As shown in Figure 14, the side wall member 304 is a rectangular plate-like member. The side wall member 304 extends along the multiple support post connecting members 303. In other words, the side wall member 304 extends in the vertical direction of the suspended scaffolding 100 and in the longitudinal direction of the first support post 102 and the second support post 202. The side wall member 304 is fixed to the support post connecting members 303 together with an inside corner covering member 316 (described later) by fastening members (not shown).

[0106] As shown in Figures 14 to 16, the projecting corner covering member 306 is installed at the projecting corner between the first scaffolding plank 104 and the side wall member 304, and covers the gap formed at the projecting corner. Figure 17 is a perspective view of the connecting portion between the first parent support pole 102 and the first support member 103, seen from a direction different from that shown in Figures 14 and 15. In Figure 17, the projecting corner covering member 306 is shown separated from the first scaffolding plank 104 and the side wall member 304. For the sake of explanation, some components are not shown in Figure 17.

[0107] As shown in FIG. 17, the projecting corner covering member 306 has a covering body 361, and a connecting retaining portion 362 and a parent support post fixing portion 363 connected to the underside of the covering body 361.

[0108] 15 to 17, the covering body 361 has a horizontal portion 361a extending horizontally and a vertical portion 361b extending downward from the end of the horizontal portion 361a. The horizontal portion 361a is placed on the upper surface of the first scaffolding board 104. The vertical portion 361b contacts the outer surface of the side wall member 304. In this way, the covering body 361 covers the gap formed at the corner between the first scaffolding board 104 and the side wall member 304.

[0109] As shown in FIG. 17, a connecting stopper part 362 and a baby support post fixing part 363 are located at the bottom of the covering part main body 361.

[0110] The covering body 361 has a suspender attachment hole 61a and an opening / closing portion 61b, similar to the covering body 61 of the gap covering member 6 in embodiment 1. The configurations of the suspender attachment hole 61a and the opening / closing portion 61b are the same as those in embodiment 1. Therefore, a description of the suspender attachment hole 61a and the opening / closing portion 61b will be omitted.

[0111] 17, the connecting retaining portion 362 extends downward from the lower surface of the covering portion main body 361. The lower end of the connecting retaining portion 362 is located rearward in the insertion direction of the first connecting portion 5 and rearward in the insertion direction of the third connecting portion 305 when the projected corner covering member 306 is installed on the projected corner portion.

[0112] In detail, in this embodiment, the connecting retaining portion 362 has a first connecting retaining portion 362a and a second connecting retaining portion 362b, each of which extends downward.

[0113] As described above, in this embodiment, the first baby support post 102 and the first support member 103 are connected by the first connecting part 5. The first baby support post 102 and the baby support post connecting member 303 are connected by the third connecting part 305. In this manner, the first connecting part 5 and the third connecting part 305 are located below the covering part main body 361. In this embodiment, the lower end of the first connecting stop part 362a is located behind the first connecting part 5, and the lower end of the second connecting stop part 362b is located behind the third connecting part 305.

[0114] The first connection retaining portion 362a restricts the backward movement of the first connecting portion 5 in the insertion direction. The second connection retaining portion 362b restricts the backward movement of the third connecting portion 305 in the insertion direction. Therefore, by installing the projected corner covering member 306 at the projected corner portion, the first connecting portion 5 is prevented from coming off from the connecting portion between the first parent support post 102 and the first support member 103, and the third connecting portion 305 is prevented from coming off from the connecting portion between the first parent support post 102 and the parent support post connecting member 303.

[0115] The baby post fixing part 363 determines the position of the projected corner covering member 306 relative to the first baby post 102. In other words, the baby post fixing part 363 connects the projected corner covering member 306 to the first baby post 102. The configuration of the baby post fixing part 363 is the same as the baby post fixing part 63 of the first embodiment. Therefore, a description of the baby post fixing part 363 will be omitted.

[0116] As shown in Figures 14 to 16, the inside corner covering member 316 is installed at the inside corner between the side wall member 304 and the second scaffolding board 204, and covers the gap formed at the inside corner. As shown in Figure 16, the inside corner covering member 316 is an L-shaped member in cross section. The inside corner covering member 316 has a horizontal portion 316a extending horizontally and a vertical portion 316b extending upward from the end of the horizontal portion 316a. The horizontal portion 316a is placed on the upper surface of the second scaffolding board 204. The vertical portion 316b contacts the outer surface of the side wall member 304.

[0117] Therefore, the inside corner covering member 316 covers the gap formed at the inside corner between the second scaffolding board 204 and the side wall member 304. The inside corner covering member 316 is fixed to the side wall member 304 and the main support post connecting member 303 by fastening members not shown. The inside corner covering member 316 has the same function as a baseboard installed along the outer edge of the scaffolding board. Therefore, the suspended scaffolding 100 may have a baseboard instead of the inside corner covering member 316.

[0118] In the suspended scaffolding 100 having the above configuration, the first support pole 102 and first support member 103 of the first scaffolding unit 101 extend horizontally at a predetermined height of the suspended scaffolding 100. The first scaffolding plank 104 is supported by the first support member 103 so as to extend horizontally. The second support pole 202 and second support member 203 of the second scaffolding unit 201 extend horizontally below the first support pole 102 and first support member 103 of the first scaffolding unit 101. The second scaffolding plank 204 is supported by the second support member 203 so as to extend horizontally. The support pole connecting member 303 connects the first support pole 102 and the second support pole 202 in the up-and-down direction.

[0119] This results in a suspended scaffolding 100 in which a plurality of second scaffolding boards 204 supported by the second support members 203 are arranged to extend horizontally at a lower position than a plurality of first scaffolding boards 104 supported by the first support members 103.

[0120] Fig. 18 is a diagram schematically showing an example of the configuration of the suspended scaffolding 100 according to this embodiment. As shown in Fig. 18, the suspended scaffolding 100 is suspended below a structure T. The height of the underside of the structure T is lower on both sides than in the center.

[0121] The suspended scaffolding 100 is composed of a first scaffolding unit 101, two second scaffolding units 201 located on either side of the first scaffolding unit 101, and parent and child support connecting members 303a, 303b that connect the first scaffolding unit 101 and the two second scaffolding units 201 in the vertical direction, respectively.

[0122] In detail, the first scaffolding unit 101 has a pair of first support posts 102a, 102b extending horizontally at a predetermined height of the suspended scaffolding 100, a first support member 103 that horizontally connects the pair of first support posts 102a, 102b, and a first scaffolding plank 104 supported by the first support member 103.

[0154] For example, the suspended scaffolding 400 shown in Figure 19 has a fourth scaffolding unit 401, a fifth scaffolding unit 501, a sixth scaffolding unit 601, and a support pole connecting member 303. The fourth scaffolding unit 401, the fifth scaffolding unit 501, and the sixth scaffolding unit 601 each have a configuration similar to the first scaffolding unit 101 or the second scaffolding unit 201 of the second embodiment.

[0155] The fourth scaffolding unit 401, which is positioned above the fifth scaffolding unit 501, has a first parent support 102. The fifth scaffolding unit 501, which is positioned below the fourth scaffolding unit 401, has a second parent support 202 below the first parent support 102 of the fourth scaffolding unit. The parent support connecting member 303 connects the first parent support 102 of the fourth scaffolding unit 401 and the second parent support 202 of the fifth scaffolding unit 501 in the vertical direction.

[0156] The fifth scaffolding unit 501, which is positioned above the sixth scaffolding unit 601, has a first support pole 102. The sixth scaffolding unit 601, which is positioned below the fifth scaffolding unit 501, has a second support pole 202 below the first support pole 102 of the fifth scaffolding unit. The support pole connecting member 303 connects the first support pole 102 of the fifth scaffolding unit 501 and the second support pole 202 of the sixth scaffolding unit 601 in the vertical direction. This makes it possible to obtain a suspended scaffolding in which multiple scaffolding planks are arranged in three tiers in one direction. Note that the suspended scaffolding may have a configuration in which multiple scaffolding planks are arranged in tiers like a descending staircase and a configuration in which multiple scaffolding planks are arranged in tiers like an ascending staircase combined together.
