Between the lower plate 14a and the upper plate 14b, there is a single pipe member 14c. The pipe member 14c and the lower plate 14a, the pipe member 14c and the upper plate 14b are fixed by reinforcing ribs 14d. In the upper section of the pipe member 14c, there is provided a bracket 14e for connecting the member locking material 50.

[0020] Two gusset plates 14f are provided in the middle section of the pipe member 14c, projecting toward the vertical support column 10 located adjacent to it in a plan view. The gusset plates 14f are used to connect the horizontal member 20 and the diagonal member 30. A backing plate 14g is provided on the upper side of both gusset plates 14f, and a bracket 14h for connecting the member locking member 50 is provided on the lower side.

[0021] The aforementioned top lower column 15 is a member connected to the upper part of the uppermost intermediate column 14. In this embodiment, the top lower column 15 comprises a lower plate 15a and an upper plate 15b. A tubular member 15c is provided between the lower plate 15a and the upper plate 15b. The tubular member 15c and the lower plate 15a, and the tubular member 15c and the upper plate 15b are fixed together by reinforcing ribs 15d.

[0022] Two gusset plates 15f are provided in the middle section of the pipe member 15c, projecting toward the vertical support column 10 located adjacent to it in a plan view. The gusset plates 15f are used to connect the horizontal member 20 and the diagonal member 30.

[0023] Between the two gusset plates 15f, there is a diagonal gusset plate 15g projecting toward the vertical support column 10, which is located opposite each other in a plan view. The diagonal gusset plate 15g is used to connect with the diagonal horizontal member 21 and the top diagonal member 43, which will be described later. A backing plate 15h is provided on the upper side of the gusset plate 15f and the diagonal gusset plate 15g, and a bracket 15i for connecting the member locking member 50 is provided on the lower side.

[0024] The upper base column 16 is a member connected to the upper part of the top lower column 15. In this embodiment, the upper base column 16 is the same structural member as the lower base column 13 and comprises a lower plate 16a, an upper plate 16b, a pipe member 16c, a reinforcing rib 16d, and a bracket 16e. The pipe member 16c and the lower plate 16a, and the pipe member 16c and the upper plate 16b are fixed by the reinforcing rib 16d, and a bracket 16e for connecting the member locking member 50 is provided in the middle section of the pipe member 16c.

[0025] The top node 17 is a member connected to the upper part of the upper base column 16. The basic configuration of the top node 17 in this embodiment is the same as that of the base node 12, and includes a lower plate 17a, an upper plate 17b, and a pipe member 17c.

[0026] The pipe member 17c is provided with two gusset plates 17d that protrude toward the vertical support column 10 located adjacent to it in a plan view. The gusset plates 17d are used to connect the horizontal member 20 and the diagonal member 30.

[0027] Between the two gusset plates 17d, there is a diagonal gusset plate 17e that protrudes toward the vertical support column 10, which is located opposite to it in a plan view. The diagonal gusset plate 17e is used to connect with the horizontal member 20 and the diagonal member 30, as well as the top horizontal member 42, which will be described later.

[0028] The horizontal members 20 are members that connect the vertical columns 10 together and are used by being positioned horizontally between the vertical columns 10 to be connected. The horizontal members 20 are provided at the positions where the base nodes 12 are connected, the positions where the intermediate columns 14 are connected, the positions where the top lower columns 15 are connected, and the positions where the top nodes 17 are connected. Each horizontal member 20 is connected to the respective gusset plates 12d, 14f, 15f, and 17d by bolts and nuts.

[0029] Between the two top-bottom columns 15 that are diagonally opposite each other in a plan view, a diagonal horizontal member 21 (Figure 1) is provided, separate from the horizontal member 20. The diagonal horizontal member 21 is connected to the diagonal gusset plate 15g of the top-bottom column 15 by bolts and nuts.

[0030] The diagonal members 30 are members that connect adjacent vertical columns 10 and are used by being positioned diagonally between the vertical columns 10 to be connected. The diagonal members 30 are provided at the positions connecting the base node 12 and the intermediate column 14 directly above it, at the positions connecting each intermediate column 14 to each other, at the position connecting the uppermost intermediate column 14 and the top lower column 15, and at the positions connecting the top lower column 15 and the top node 17. Each diagonal member 30 is connected to each gusset plate 12d, 14f, 15f, and 17d by bolts and nuts.

[0031] Of the horizontal members 20, member locking members 50 are provided on the lower side of the horizontal member 20 connecting the base nodes 12, the lower side of the horizontal member 20 connecting the intermediate columns 14, and the lower side of the horizontal member 20 connecting the top lower columns 15. The member locking members 50 are connected to brackets 13e, 14e, 14h, 15e, 15i, and 16e by bolts and nuts.

[0032] The component locking member 50 is used for purposes such as erecting scaffolding planks 51 during the assembly and dismantling of the support structure, hooking the upper part of the stairs 52, and supporting the leading handrail 53.

[0033] As shown in Figures 1 and 3, a support member 41 is provided at the center position (a central part within a certain range) of the upper end of the shoring (the uppermost part in the illustrated example). As shown in Figure 4, the support member 41 in this embodiment comprises a top plate portion 41a and a flange 41b projecting downward from the lower surface of the top plate portion 41a.

[0034] The upper surface of the top plate portion 41a of the support member 41 is provided with a support surface capable of supporting a structure or jack X. Each flange 41b is flat and there are four of them, spaced evenly apart. Each flange 41b is provided with two holes 41c through which connecting bolts can be inserted.

[0035] One end of each flange 41b is connected to the top horizontal member 42 by bolts and nuts. The other end of each top horizontal member 42 is connected to the diagonal gusset plate 17e of the top node 17 by bolts and nuts.

[0036] Furthermore, one end of each flange 41b is connected to the top diagonal member 43 with a bolt and nut. The other end of each top diagonal member 43 is connected to the diagonal gusset plate 15g of the top lower column 15 with a bolt and nut.

[0037] The angle of the top diagonal member 43 is steeper than that of the diagonal member 30. In other words, the angle between the top diagonal member 43 and a virtual line parallel to the installation surface of the shoring (hereinafter referred to as the "virtual reference line") is greater than the angle between the virtual reference line and the diagonal member 30.

[0038] There are no restrictions on the angle between the virtual reference line and the top diagonal member 43, but this angle can be 45 degrees or more, preferably 55 degrees or more, and more preferably 60 degrees or more, within a range of less than 90 degrees. The steeper this angle, the smaller the load acting on the top diagonal member 43 can be, and the smaller the required cross-section of the top diagonal member 43 can be (the smaller the weight of the member).

[0039] In this embodiment, four top horizontal members 42 and four top diagonal members 43 are used. The four top diagonal members 43 are arranged to form the four hypotenuses of a square pyramid. The support member 41, supported by the top horizontal members 42 and top diagonal members 43, has its upper surface flush with or protruding above the upper end surface of the base of the shoring. However, the upper surface of the support member 41 may also be lower than the upper end surface of the base of the shoring.

[0040] The materials used to construct the shoring described here may be steel, aluminum, or other materials such as FRP. Furthermore, the connection between the gusset plates 12d, 14f, 15f, 17d, the diagonal gusset plates 15g, 17e, and the brackets 13e, 14e, 14h, 15e, 15i, 16e and the vertical support columns 10 may be made by welding, or by drilling holes in the vertical support columns 10 and fastening them with bolts.

[0041] The configuration of the embodiment described herein is merely an example, and the scaffolding and structural support structure of the present invention is not limited to the configuration of the embodiment described above. The scaffolding and structural support structure of the present invention can be modified as appropriate, such as by adding, replacing, or omitting components, to the extent that the intended purpose can be achieved.

[0042] For example, in the above embodiment, a rectangular prism-shaped support structure with four vertical support columns 10 is used as an example, but there may be more or fewer than four vertical support columns 10, and their shape can also be a triangular prism or a polygonal prism of pentagonal or more.

[0043] Furthermore, the positions and number of horizontal members 20, diagonal horizontal members 21, diagonal members 30, top horizontal members 42, and top diagonal members 43 in the above embodiment can be appropriately changed according to the size of the shoring, and may be in different positions or numbers than those in the above embodiment.

[0044] Next, the assembly procedure for the support structure of the above embodiment will be described with reference to the drawings. (1) As shown in Figures 5(a) and 5(b), a base node 12 is connected to the upper side of the misalignment fitting 11, and a lower base column 13 is connected to the upper side of the base node 12. The base nodes 12 are connected to each other with a horizontal member 20. A member locking member 50 is installed on the lower side of the horizontal member 20, and the plank 51 is installed using this member locking member 50. (2) After the process in (1) above, as shown in Figures 6(a) and (b), the intermediate column 14 is connected to the upper side of the lower base column 13, and the installed intermediate column 14 and the base node 12 are connected with diagonal members 30. The intermediate columns 14 are connected to each other with horizontal members 20. Member locking members 50 are installed on the lower side of the horizontal members 20, and the planks 51, stairs 52 and handrails 53 are installed using these member locking members 50. (3) After the process in (2) above, as shown in Figures 7(a) and (b), the second intermediate column 14 is connected to the upper side of the first intermediate column 14, and the second intermediate column 14 and the first intermediate column 14 are connected with diagonal members 30. The second intermediate columns 14 are connected to each other with horizontal members 20. Member locking members 50 are installed on the lower side of the horizontal members 20, and the planks 51, stairs 52 and lead handrails 53 are installed using these member locking members 50. (4) After the process in (3) above, the third intermediate column 14 is connected, the second intermediate column 14 and the third intermediate column 14 are connected with diagonal members 30, the third intermediate columns 14 are connected to each other with horizontal members 20, the member locking members 50 are installed, and the planks 51, stairs 52 and lead handrails 53 are installed using the member locking members 50 (Figure 8(a)(b)). (5) After step (4) above, as shown in Figures 9(a) and (b), the top lower column 15 is connected to the upper side of the third intermediate column 14, and the third intermediate column 14 and the top lower column 15 are connected with diagonal members 30. The top lower columns 15 are connected to each other with horizontal members 20. Member locking members 50 are installed on the lower side of the horizontal members 20, and the planks 51, stairs 52 and lead handrails 53 are installed using these member locking members 50. (6) After step (5) above, as shown in Figures 10(a) and (b), the upper base column 16 is connected to the upper side of the top lower column 15, and the top node 17 is connected to the upper side of the upper base column 16. The top lower column 15 and the top node 17 are connected with diagonal members 30, and the top nodes 17 are connected to each other with horizontal members 20. (7) After step (6) above, as shown in Figures 11(a) and (b), the other end of the top diagonal member 43, which has one end connected to the support member 41, is connected to the top lower column 15, and the other end of the top horizontal member 42, which has one end connected to the support member 41, is connected to the top node 17. A height-adjusting jack X (for example, a giraffe jack) is installed on the upper surface of the support member 41.

[0045] In conventional scaffolding consisting of four support columns, two sets of main beams (Y) were often placed on top of the two outermost columns to support the load. This meant that if the load was unbalanced, the scaffolding could become unstable. In contrast, in the scaffolding of this embodiment, the load is received at the center of the scaffolding, making load imbalance less likely, resulting in superior safety and reliable work execution. Furthermore, since there is only one set of main beams (Y), the top structure is simplified, leading to increased efficiency.

[0046] In assembling the scaffolding of this embodiment, worker safety can be ensured by utilizing the planks 51 and handrails 53 installed inside the scaffolding.

[0047] The shoring of this embodiment can be assembled at a designated location on the construction site in the manner described above, and then used by placing a jack X on the upper surface of the top plate portion 41a of the support member 41. Specifically, by placing a main beam member Y on the upper surface of the jack X and adjusting the height of the main beam member Y with the jack X, the object to be supported can be supported on the upper surface of the main beam member Y.

[0048] In this embodiment, when the shoring is assembled in the manner described above at a designated location on the construction site, there are planks 51 and handrails 53 inside the shoring that serve as a working platform, so the components can be assembled safely using these.

[0049] When a structure is supported in this manner, the support structure, as shown in Figure 12, consists of a jack X placed on the upper surface of the top plate portion 41a of the support member 41 of the shoring, a main beam Y placed on the upper surface of the jack X, and the structure being supported by the main beam Y.

[0050] The main beam Y can be used as needed and can be omitted if not required. In this case, in addition to directly supporting the structure with the jack X, a thin plate such as straw can be placed on the top surface of the jack X, and the structure can be supported via the straw.

[0051] Previously, adjusting the height of shoring was done by changing the height of the columns, but this method resulted in a large number of column types and required the creation of corresponding drawings, which was a heavy workload. Furthermore, fine height adjustments were handled by using thin sheets such as liners, which was inefficient.

[0052] In contrast, the shoring system of this embodiment allows for easy height adjustment using jack X, thus eliminating the aforementioned workload and inefficiencies. Furthermore, the ease of height adjustment contributes to reduced working time and improved safety.

[0053] The assembly procedure described here is just one example, and the assembly procedures for the scaffolding within each process can be rearranged or omitted as appropriate.

[0054] For example, scaffolding can be assembled into blocks near a designated location at the construction site to a certain height, and then attached to scaffolding that has been pre-assembled at the designated location using lifting equipment such as cranes. This method allows for faster assembly of scaffolding. In addition, scaffolding can also be assembled in a panel-like manner to form a surface material.

[0055] The shoring can be dismantled by reversing the assembly procedure described in (1) to (7) above, but, as with the assembly procedure, the dismantling procedure for the shoring within each process can be rearranged or omitted as appropriate. The shoring in this embodiment uses jacks X, which has the advantage of making it easy to release the load and easy to dismantle.

[0056] The matters disclosed in this application are examples only and do not constitute a basis for restricting the technical scope of the present invention. The technical scope of the present invention is defined based on the claims. Furthermore, the technical scope of the present invention includes equivalents to the claims. [Industrial applicability]

[0057] The scaffolding and structural support structure of the present invention can be suitably used in various construction works, including building construction, bridge construction such as road bridges and railway bridges. [Explanation of Symbols]
