Description

[Technical Field]

[0001] The present invention relates to an assembled column that can be used as a hollow column, a piping column, or the like. [Background technology]

[0002] At various construction sites, hollow prefabricated columns made from various materials, such as concrete pipes (Hume pipes), metal steel pipes, and even resin pipes such as PVC, are used for utility poles, telegraph poles, traffic signs, and piping at various construction sites. However, the volume of the hollow portion of the column structure increases during transportation and storage, making them difficult to transport and store. Therefore, prefabricated columns have been proposed to improve the efficiency of transportation and storage (see, for example, Patent Documents 1 and 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Jikko No. 53-16821 [Patent Document 2] Special Publication No. 58-46994 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the assembled columns of the above-mentioned Patent Documents 1 and 2, the multiple vertical members (referred to as base materials in Patent Document 2) that make up the assembled column are divided, i.e., independent, and these multiple vertical members are joined on-site, etc., which poses the problem of poor assembly workability on-site.

[0005] Therefore, the present invention has been made in consideration of the above problems, and has an object to provide an assembled column that can improve the ease of assembly work on site. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems, the assembled column according to the present invention is an assembled column formed by connecting a plurality of hollow column structures connected in a row via bendable flexible connecting parts by bending the respective flexible connecting parts, wherein each of the plurality of column structures has a column structure outer side surface that is continuous with an adjacent other column structure via the flexible connecting parts, a pair of column structure lateral side surfaces hanging down from both the left and right sides of the column structure outer side surface, and a column structure inner side surface that is provided from the lower ends of the pair of column structure lateral side surfaces to face the column structure outer side surface, and is characterized in that the column structure lateral side surfaces of the plurality of column structures are on the outside and the column structure inner side surfaces are on the inside, and an assembled column surrounded by the column structure inner side surfaces of the plurality of column structures is formed by bending the column structure lateral side surfaces of the plurality of column structures in either a clockwise direction or a counterclockwise direction at the flexible connecting parts so that the column structure lateral side surfaces of adjacent column structures are in close contact with each other. Furthermore, in the assembled column according to the present invention, when connecting the front or rear ends of the plurality of column constituents, the column constituent that will be the male side is provided with a male coupling part, while the column constituent that will be the female side is provided with a female coupling part that couples to the male coupling part, and by coupling the male coupling part and the female coupling part, the plurality of column constituents are bent in the one direction at the flexible coupling part, with the lateral side surfaces of the column constituents facing outwards and the internal side surfaces of the column constituents facing inwards, and the lateral side surfaces of the column constituents of adjacent column constituents come into close contact with each other, thereby forming the central hollow part of the assembled column. Furthermore, in the assembled column according to the present invention, the column constituent which serves as the male side is provided with an outer male coupling portion which extends flush with the outer peripheral surface of the column constituent, and a vertical mushroom-shaped engagement protrusion which protrudes vertically from the outer male coupling portion in a thickened mushroom shape, while it is provided with an inner male coupling portion which extends flush with the inner peripheral surface of the column constituent, and a fishhook-shaped engagement protrusion whose tip is inclined like a triangular slope, and the outer peripheral surface of the column constituent which serves as the female side is provided with a vertical mushroom-shaped engagement recess into which the vertical mushroom-shaped engagement protrusion of the outer male coupling portion of the column constituent which serves as the male side fits, and a coupling recess into which the outer male coupling portion fits, while it is also characterized in that the inner peripheral surface of the column constituent is provided with a fishhook-shaped engagement recess into which the fishhook-shaped engagement protrusion of the inner male coupling portion of the column constituent which serves as the male side fits, and a coupling recess into which the inner male coupling portion fits. Furthermore, the assembled column according to the present invention is characterized in that a pair of lateral side surfaces of the plurality of column structures are each provided with a convex portion or a concave portion that fit together when brought into close contact with the lateral side surface of an adjacent column structure. Furthermore, in the assembled column according to the present invention, of the plurality of column structures, the column structures at the front and rear ends are respectively composed of a column structure having a height α / (α + β) higher than the column structures other than the front and rear ends and a column structure having a height β / (α + β), and when the lateral side surfaces of the plurality of column structures are on the outside and the internal side surfaces of the column structures are on the inside, and when an assembled column structure hollow portion surrounded by the internal side surfaces of the plurality of column structures is formed by bending the column structure lateral side surfaces of the plurality of column structures in either a clockwise direction or a counterclockwise direction by the flexible connecting part so that the lateral side surfaces of the column structures of adjacent column structures come into close contact with each other, one of the column structures having a height α / (α + β) and the other column structure having a height β / (α + β) overlap in the radial direction when the assembled column is assembled. Furthermore, in the assembled column according to the present invention, one of the plurality of column structures, which is connected to one of the column structures having a height of α / (α + β) via the flexible connecting part, is provided with a male connecting part, while the other of the column structures having a height of β / (α + β) is provided with a female connecting part that connects to the male connecting part, and by connecting the male connecting part and the female connecting part, the plurality of column structures are bent in the one direction at the flexible connecting part so that the lateral side surfaces of the column structures are on the outside and the internal side surfaces of the column structures are on the inside, the lateral side surfaces of the column structures of adjacent column structures come into close contact with each other to form the assembled column hollow part, and the one column structure having a height of α / (α + β) and the other column structure having a height of β / (α + β) overlap in the radial direction when the assembled column is assembled. Note that the above-mentioned α and β are any natural numbers and may be the same or different natural numbers. Furthermore, the assembled column according to the present invention is characterized in that a pair of lateral side surfaces of the plurality of column constituents are each provided with a thick-tipped mushroom-shaped convex portion or a wide-bottomed mushroom-shaped concave portion that fit together when brought into close contact with the lateral side surface of an adjacent column constituent. [Effects of the Invention]

[0007] The assembled column of the present invention is formed by bending a plurality of integrally molded column components connected in a row via bendable flexible connecting parts in either a clockwise or counterclockwise direction at the flexible connecting parts so that the lateral side surfaces of each of the plurality of column components are on the outside and the internal side surfaces of each of the plurality of column components are on the inside, and when the lateral side surfaces of each of the adjacent column components are brought into close contact with each other, a central hollow section of the assembled column is formed that is surrounded by the internal side surfaces of the plurality of column components. Furthermore, when forming an assembled column on site, multiple integrally molded column components connected in a row are bent in one direction and then both ends are fastened together to complete the column, thereby improving the ease of assembling the assembled column on site. Furthermore, before the assembled column is formed, the plurality of column components are connected in a row via flexible connecting parts, so that the volume is small during transportation and storage, improving space efficiency. Furthermore, when an assembled column is formed, the lateral side surfaces of the multiple column constituents are in close contact with each other, and a central hollow section of the assembled column is formed surrounded by the internal side surfaces of the multiple column constituents, thereby improving strength and enabling the cross-sectional performance related to column strength to be evaluated using the section modulus.

DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, assembled columns 1 and 1' according to embodiments 1 and 2 of the present invention will be described with reference to the drawings. Note that the embodiments described below are merely examples of the present invention, and the present invention is not limited to the following embodiments, and can be modified as appropriate within the scope of the technical concept of the present invention.

[0010] Embodiment 1. <Configuration of assembled column 1 of embodiment 1> The assembled column 1 of embodiment 1 according to the present invention is a component that forms a column shape as shown in FIG. 1, etc., by bending and connecting 12 hollow column components 11 connected in a row via bendable flexible connecting parts 12 as shown in FIG. 3, and is formed integrally from, for example, synthetic resin, metal, etc.

[0011] Here, of the 12 column components 11, the column components 11 at both ends are provided with male coupling portions 11e, 11f or female coupling portions 11g, 11h, which will be described later, so the column components 11 provided with male coupling portions 11e, 11f will be called male side column components 11M, and the female side column components 11 provided with female coupling portions 11g, 11h will be called female side column components 11F.

[0012] (Column structure 11) Each of the twelve column constituents 11, including the male side column constituent 11M and the female side column constituent 11, has a column constituent outer peripheral surface 11a that is continuous with other adjacent column constituents 11 via flexible connecting parts 12, a pair of column constituent lateral side surfaces 11b, 11b hanging down from both the left and right sides of the column constituent outer peripheral surface 11a, and a column constituent inner peripheral surface 11c that is provided from the tips of the pair of column constituent lateral side surfaces 11b, 11b so as to face the column constituent outer peripheral surface 11a, and has a column constituent hollow part 11d that is surrounded by the column constituent outer peripheral surface 11a, the column constituent lateral side surfaces 11b, 11b and the column constituent inner peripheral surface 11c.

[0013] The twelve column constituent bodies 11 are bent in either a clockwise or counterclockwise direction by the flexible connecting parts 12 so that the column constituent outer surfaces 11a are on the outside and the column constituent inner surfaces 11c are on the inside, and the column constituent lateral surfaces 11b, 11b of adjacent column constituent bodies 11 are in close contact with each other via the flexible connecting parts 12 and lined up closely at the center of the circle, i.e., in the radial direction, to form an assembled column central hollow part 13 surrounded by the column constituent inner surfaces 11c of the twelve column constituent bodies 11.

[0014] As shown in Figures 3 and 4, etc., the right-side column component lateral side surface 11b of each of the 12 column components 11 is provided with a semicircular convex portion 11b1 having a nearly semicircular shape that fits into the semicircular concave portion 11b2 on the left-side column component lateral side surface 11b of another column component 11 adjacent on the right side, while the left-side column component lateral side surface 11b is provided with a semicircular concave portion 11b2 that is recessed in a nearly semicircular shape that fits into the semicircular convex portion 11b1 on the right-side column component lateral side surface 11b of another column component 11 adjacent on the left side.

[0015] (Male side pillar component 11M) Furthermore, of the two end portions of the 12 column components 11, the male column component 11M, which is the column component 11 at the left end in Figure 3, has an outer male coupling portion 11e that is flush with the column component outer peripheral surface 11a, and an inner male coupling portion 11f that is flush with the column component inner peripheral surface 11c, as shown in Figures 3 and 4.

[0016] As shown in Figures 3 and 4, the outer male coupling portion 11e is provided with a vertical mushroom-shaped engagement protrusion 11e1 that protrudes vertically in the shape of a thick mushroom from a point that returns from the tip toward the male side pillar component 11M by a predetermined length, while the inner male coupling portion 11f is provided with a fishhook-shaped engagement protrusion 11f1 whose tip is inclined like a triangular slope, like a fishhook, when viewed from above.

[0017] (Female side column component 11F) In contrast, of the two end portions of the 12 column components 11, the column component outer peripheral surface 11a of the female side column component 11F, which is the right-most column component 11, is provided with a vertical mushroom-shaped engagement recess 11g1 with a wide base that fits the vertical mushroom-shaped engagement protrusion 11e1 of the outer male coupling portion 11e provided on the column component outer peripheral surface 11a of the left-most male side column component 11M, as shown in Figures 3 and 5, and a coupling recess 11g into which the outer male coupling portion 11e fits, while a fishhook-shaped engagement recess 11h1 that is triangular in plan view and fits into which the fishhook-shaped engagement protrusion 11f1 provided on the column component inner peripheral surface 11c of the right-most female side column component 11F fits, and a coupling recess 11h into which the inner male coupling portion 11f fits, are provided.

[0018] <Function of the assembled column 1 of the first embodiment> Next, the operation of the assembled column 1 of the first embodiment configured as above will be described.

[0019] (When the assembly column 1 of the first embodiment is deployed) When manufacturing is complete, when storing in a warehouse or the like, or when transporting by truck or the like, the male side column component 11M on the left end and the female side column component 11F on the right end are not connected as shown in Figure 3, and do not form an assembled column 1 having a central hollow portion 13 for the assembled column, so they only have a thickness roughly the same as the height of the column component 11. Therefore, when manufacturing is complete or when storing in a warehouse or the like, no storage space is required, resulting in good space efficiency.

[0020] (When the assembled column 1 of embodiment 1 is rolled to form a cylindrical (columnar) column material) In contrast to this, when the assembled column 1 of embodiment 1 in the unfolded state as shown in Figure 3 is transported to the site and then rolled up to assemble the assembled column 1 having the central hollow portion 13 of the assembled column, at the site, first, each of the 12 column constituents 11 in the assembled column 1 of embodiment 1 in the unfolded state as shown in Figure 3 is bent in either the clockwise or counterclockwise direction at the flexible connecting parts 12 so that the column constituent outer surfaces 11a are on the outside and the column constituent inner surfaces 11c are on the inside, and the column constituent lateral surfaces 11b, 11b of adjacent column constituents 11 are closely contacted and lined up in the radial direction via the flexible connecting parts 12, thereby forming the assembled column central hollow portion 13 surrounded by the column constituent inner surfaces 11c of the 12 column constituents 11 as shown in Figures 1 and 2, etc.

[0021] Then, the column components 11 at both ends of the 12 column components 11, the leftmost male column component 11M and the rightmost female column component 11F in Figure 3, move closer to each other as shown in Figure 6, and as shown in Figure 7, the outer male coupling portion 11e on the column component outer surface 11a of the leftmost male column component 11M fits so as to overlap with the coupling recess 11g on the column component outer surface 11a of the rightmost female column component 11F, and the vertical mushroom-shaped engaging protrusion 11e1 of the outer male coupling portion 11e fits into the vertical mushroom-shaped engaging recess 11g1 of the coupling recess 11g.

[0022] As shown in Figure 7, the inner male coupling portion 11f on the inner peripheral surface 11c of the column component of the left-end male side column component 11M fits so as to overlap with the coupling recess 11h on the inner peripheral surface 11c of the column component of the right-end female side column component 11F, and the fishhook-shaped engagement protrusion 11f1 of the inner male coupling portion 11f fits into the fishhook-shaped engagement recess 11h1 of the coupling recess 11h, thereby forming a column material as shown in Figures 1 and 2, etc.

[0023] <Summary of the assembly column 1 of the first embodiment> As explained above, according to the assembled column 1 of the present invention, among the 12 column constituents 11, the male column constituent 11M, which is the leading or trailing end male column constituent 11, is provided with an outer male coupling portion 11e flush with the column constituent outer peripheral surface 11a and an inner male coupling portion 11f flush with the column constituent inner peripheral surface 11c, while the female column constituent 11F, which is the female column constituent 11, is provided with a coupling recess 11g on its column constituent outer peripheral surface 11a with which the outer male coupling portion 11e of the male column constituent 11M engages and an inner male coupling portion 11f on its column constituent inner peripheral surface 11c. The male side column component 11M has a connecting recess 11h into which the inner male connecting portion 11f of the male side column component 11M engages, and by connecting the outer male connecting portion 11e and the inner male connecting portion 11f of the male side column component 11M to the connecting recess 11g and the connecting recess 11h of the female side column component 11F, the 12 column components 11 are bent in one direction by the flexible connecting portions 12 so that the outer peripheral surface 11a of the column component faces outward and the inner peripheral surface 11c of the column component faces inward, and the lateral side surfaces 11b, 11b of the column components of adjacent column components 11 come into close contact with each other to form a column material having a central hollow portion 13 of the assembled column.

[0024] Therefore, before the column material is formed, the 12 column components 11 are connected in a row via flexible connecting parts 12 in an integrally molded state, and since no central hollow section 13 of the assembled column is formed, the volume is small during transportation and storage, improving space efficiency.On the other hand, when the column material arrives at the site, a column material having a central hollow section 13 of the assembled column can be formed by connecting the male side column components 11M and female side column components 11F at both ends of the 12 column components 11 that have been integrally formed.This means that transportation and storage can be performed in a small volume, and by forming a column material having a central hollow section 13 of the assembled column on site, it is possible to provide an assembled column 1 that is lightweight.

[0025] In particular, in the assembled column 1 of this embodiment 1, the male side column component 11M at the front or rear end of the 12 column components 11 is provided with an outer male coupling portion 11e that is flush with the outer peripheral surface 11a of the column component and an inner male coupling portion 11f that is flush with the inner peripheral surface 11c of the column component, while the female side column component 11F on the female side is provided with a coupling recess 11g on the outer peripheral surface 11a of the column component with which the outer male coupling portion 11e of the male side column component 11M engages, and a coupling recess 11h on the inner peripheral surface 11c of the column component with which the inner male coupling portion 11f of the male side column component 11M engages.Therefore, when forming a column material having a central hollow portion 13 of the assembled column, it can be connected at two points, the outer peripheral surface 11a of the column component and the inner peripheral surface 11c of the column component, thereby further improving the strength of the column material.

[0026] Furthermore, in the assembled column 1 of embodiment 1 according to the present invention, the outer male coupling portion 11e, which is flush with the outer peripheral surface 11a of the column component of the male side column component 11M, is provided with a vertical mushroom-shaped engagement protrusion 11e1 that protrudes vertically from the outer male coupling portion 11e in the shape of a thick mushroom, while the inner male coupling portion 11f, which is flush with the inner peripheral surface 11c of the column component, is provided with a fishhook-shaped engagement protrusion 11f1 whose tip is inclined like a triangular slope, and the outer peripheral surface 11a of the column component of the female side column component 11F is provided with a vertical mushroom-shaped engagement recess 11g1 into which the vertical mushroom-shaped engagement protrusion 11e1 of the outer male coupling portion 11a of the male side column component 11M fits, and the inner peripheral surface 11c of the column component is provided with a fishhook-shaped engagement recess 11h1 into which the fishhook-shaped engagement protrusion 11f1 of the inner male coupling portion 11f of the male side column component 11M fits.

[0027] Therefore, since the vertical mushroom-shaped engagement protrusion 11e1 of the outer male coupling portion 11e of the male side column component 11M and the fishhook-shaped engagement protrusion 11f1 of the inner male coupling portion 11f protrude in different directions, the male side column component 11M and the female side column component 11F can be reliably and firmly coupled together, further improving the strength of the column material.

[0028] In particular, as is clear from Figure 6, when connecting the male side post component 11M and the female side post component 11F, the fishhook-shaped engagement protrusion 11f1 of the inner male coupling portion 11f of the male side post component 11M, which has a greater engagement angle and stronger engagement force than the vertical mushroom-shaped engagement recess 11g1 of the outer male coupling portion 11g of the female side post component 11F, fits into the fishhook-shaped engagement recess 11h1 of the inner male coupling portion 11f of the female side post component 11F, and then the vertical mushroom-shaped engagement protrusion 11e1 of the outer male coupling portion 11e of the male side post component 11M fits into the vertical mushroom-shaped engagement recess 11g1 of the outer male coupling portion 11g of the female side post component 11F, making it easier to connect the male side post component 11M and the female side post component 11F and improving the workability of assembling the post materials.

[0029] Embodiment 2. Next, an assembled column 1' according to a second embodiment of the present invention will be described. <Configuration of the assembled column 1′ of the second embodiment> The assembled column 1' of embodiment 2 of the present invention is characterized in that, as shown in Figure 10, nine normal-sized column components 11' are arranged in series, and at one end thereof a normal-sized first male side column component 11M1' and a second male side column component 11M2' whose height is half the size are provided, while at the other end thereof a normal-sized first female side column component 11F1' and a second female side column component 11F2' whose height is half the size are provided, and these are rolled clockwise or counterclockwise as shown in Figures 8 and 9, etc., so that the inner circumferential surfaces 11c', 11M1c', 11F1c', 11F2c' of these column components are facing inward, and the first male side column component 11M1' and the second male side column component 11M2' and the first female side column component 11F1' and the second female side column component 11F2' are connected to form the column material shown in Figures 8 and 9, etc.

[0030] In other words, in the assembled column 1' of embodiment 2 of the present invention, the column components that contribute to the connection are different from the male side column component 11M and female side column component 11F in the assembled column 1 of embodiment 1 described above, and are characterized by being two sets of a first male side column component 11M1' and a second male side column component 11M2' and a first female side column component 11F1' and a second female side column component 11F2' on the male side and the female side, respectively.

[0031] (Column structure 11') Each of the nine column constituents 11', similarly to the ten column constituents 11 in the assembled column 1 of the first embodiment described above, has a column constituent outer peripheral surface 11a' that is continuous with other adjacent column constituents 11' via flexible connecting parts 12', a pair of column constituent lateral side surfaces 11b', 11b' hanging down from both the left and right sides of the column constituent outer peripheral surface 11a', and a column constituent inner peripheral surface 11c' that is provided from the tips of the pair of column constituent lateral side surfaces 11b', 11b' so as to face the column constituent outer peripheral surface 11a', and has a column constituent hollow portion 11d' that is surrounded by the column constituent outer peripheral surface 11a', the column constituent lateral side surfaces 11b', 11b' and the column constituent inner peripheral surface 11c'.

[0032] The nine column constituents 11' are bent in either a clockwise or counterclockwise direction by the flexible connecting parts 12' so that the column constituent outer surfaces 11a' are on the outside and the column constituent inner peripheral surfaces 11c' are on the inside, and the column constituent lateral surfaces 11b', 11b' of adjacent column constituents 11' are in close contact with each other via the flexible connecting parts 12' and are lined up closely at the center of the circle, i.e., in the radial direction, to form an assembled column central hollow part 13' surrounded by the column constituent inner peripheral surfaces 11c' of the 12 column constituents 11', thereby forming the column material of embodiment 2 shown in Figures 8 and 9.

[0033] Unlike the assembled column 1 of embodiment 1, the right-side column component lateral side surface 11b' of each of the nine column components 11' is provided with two mushroom-shaped convex portions 11M1b1', 11M1b1' which are approximately thick at the tip and which fit into two wide-base mushroom-shaped small-mushroom-shaped concave portions 11b2', 11b2' provided at a predetermined interval on the left-side column component lateral side surface 11b' of another adjacent column component 11' on the right side, as shown in Figures 10 to 12, etc., while the left-side column component lateral side surface 11b' is provided with small mushroom-shaped concave portions 11b2', 11b2' which are recessed into a wide mushroom shape and fit into the mushroom-shaped convex portions 11b1', 11b1' of the right-side column component lateral side surface 11b' of another adjacent column component 11' on the left side.

[0045] <Function of the assembled column 1' of the second embodiment> Next, the operation of the assembled column 1' of the second embodiment configured as above will be described.

[0046] (When the assembly column 1' of the second embodiment is deployed) When manufacturing is complete, when storing in a warehouse or the like, or when transporting by truck or the like, the first male side column component 11M1' and second male side column component 11M2' on the left side in Fig. 10 are not connected to the first female side column component 11F1' and second female side column component 11F2' on the right side, as in the assembled column 1 of embodiment 1 shown in Fig. 3, and do not constitute an assembled column 1' having an assembled column central hollow portion 13', so that the column component 11' has a thickness approximately the same as the height of the column component 11'. Therefore, when manufacturing is complete, when storing in a warehouse or the like, or when transporting by truck or the like, no extra space is required, resulting in good space efficiency.

[0047] (When the unfolded assembled column 1' of the second embodiment is rolled to form a cylindrical (columnar) column material) In contrast, the assembled column 1' of embodiment 2 in the unfolded state is transported to the site and assembled, that is, the nine column constituents 11', the first male side column constituent 11M1', the second male side column constituent 11M2' and the first female side column constituent 11F1' constituting the assembled column 1' of embodiment 2 are arranged with their column constituent outer peripheral surfaces 11a', 1cM1a', 11M2a', 11F1a' facing outwards, and the column constituent inner peripheral surfaces 11c', 1cM1c', 11F1c', 11F2c' of the nine column constituents 11', the first male side column constituent 11M1', the first female side column constituent 11F1' and the second female side column constituent 11F2' facing inwards. Furthermore, the nine adjacent pillar components 11', the first male side pillar component 11M1', the second male side pillar component 11M2', the first female side pillar component 11F1' and the second female side pillar component 11F2' are tightly attached via the flexible connecting portion 12' and bent so that they are lined up closely in the center of the circle, i.e., in the radial direction, to form an assembled pillar central hollow portion 13' surrounded by the pillar component outer surfaces 11c', 1cM1c', 11F1c', 11F2c' of the nine pillar components 11', the first male side pillar component 11M1', the first female side pillar component 11F1' and the second female side pillar component 11F2' as shown in Figures 8 and 9, etc.

[0048] As a result, the first male side column component 11M1' and the second male side column component 11M2' on the left side in Figure 10 and the first female side column component 11F1' and the second female side column component 11F2' on the right side are connected as shown in Figure 12 to form an assembled column 1' of embodiment 2 having a central hollow portion 13' in the assembled column.

[0049] Specifically, as shown in Figure 13, the mushroom-shaped convex portion 11F1b3' of the first female side post component lateral side surface 11F1b' on the right side of the first female side post component 11F1' fits into the mushroom-shaped concave portion 11M2b3' of the second male side post component 11M2', and the mushroom-shaped convex portion 11F1b1' of the first female side post component lateral side surface 11F1b' on the right side of the first female side post component 11F1' fits into the mushroom-shaped concave portion 11F2b2' of the second female side post component lateral side surface 11F2b' on the left side of the second female side post component 11F2'.

[0050] Furthermore, between the second male side post component 11M2' and the second female side post component 11F2', as shown in Figure 13, the mushroom-shaped convex portion 11M2c3' on the second male side post component inner surface 11M2c' of the second male side post component 11M2' fits into the mushroom-shaped concave portion 11F2a3' on the second female side post component outer surface 11F2a' of the second female side post component 11F2'.

[0051] As shown in FIG. 13, the mushroom-shaped protrusion 11M2b1' of the second male side post component 11M2' fits into the mushroom-shaped recess 11M1b2' of the left side post component lateral surface 11b' of the first male side post component 11M1', and the mushroom-shaped recess 11M1b3' of the second female side post component 11F2' fits into the mushroom-shaped recess 11M1b3' of the first male side post component lateral surface 11M1b' of the left side of the first male side post component 11M1'. The mushroom-shaped convex portion 11F2b3' of the lateral surface 11F2b' of the second female side post component on the right side engages, and the fishhook-shaped engagement protrusion 11M1f1' of the inner male coupling portion 11M1f' on the inner circumferential surface 11M1c' of the first male side post component 11M1' engages with the fishhook-shaped engagement recess 11F2cf1' on the inner circumferential surface 11F2c' of the second female side post component 11F2'.

[0052] Therefore, in the case of the assembled column 1' of the second embodiment, the number of fitting portions is increased compared to the case of the assembled column 1 of the first embodiment, so that a column material with stronger fitting can be formed.

[0053] <Summary of the assembly column 1' of the second embodiment> As described above, according to the assembled column 1' of embodiment 2 of the present invention, similarly to the assembled column 1 of embodiment 1, before the column material is formed, nine normal-sized column components 11', the first male side column component 11M1' and the first female side column component 11F1', and the second male side column component 11M2' and the second female side column component 11F2' which are half the height, are connected in a row via flexible connecting parts 12'. This reduces the volume during transportation and storage, improving space efficiency, and at the same time, a lightweight column material can be formed by connecting the integrally molded column components 11', the first male side column component 11M1' and the first female side column component 11F1', and the second male side column component 11M2' and the second female side column component 11F2' on site.

[0054] In particular, in the assembled column 1' of this embodiment 2, the first male side column component 11M1' and the second male side column component 11M2' on the left side in Figure 10 and the first female side column component 11F1' and the second female side column component 11F2' on the right side are connected as shown in Figure 12 to form the assembled column 1' of embodiment 2 having a central hollow portion 13' of the assembled column, so that the number of fitting points is increased compared to the assembled column 1 of embodiment 1, and a column material with a more firmly fitted fit can be formed.

[0055] In the description of the assembled columns 1, 1' in the above embodiments 1 and 2, the shape in a plan view after assembly, i.e., the cross-sectional shape, has been described as a cylindrical (cylinder) column having a circular or pipe shape. However, the present invention is not limited to this, and it is of course possible to configure the shape in a plan view after assembly to be a dodecagon, octagon, hexagon, square, etc., and the shape of the column material after assembly to be a dodecagonal column, octagonal column, hexagonal column, square column, triangular column, etc., other than a cylindrical (cylinder) column.

[0056] Furthermore, in the description of the assembled column 1' in the above embodiment 2, α = β = 1, and the height of both the second male side column component 11M2' and the second female side column component 11F2' is configured to be half the height of the other nine column components 11', the first male side column component 11M1', and the first female side column component 11F1'. However, the present invention is not limited to this, and α and β may of course be set to different natural numbers. [Explanation of symbols]
