Divided body, support member for a column, and method for installing a column ,
[0001] The present invention relates to a divided body for constituting a support member for a column, a support member for a column using the same, and a method for installing a column using the support member for a column.
[0002] Conventionally, when installing fixtures such as fences, signboards, and signs on the ground, a support member for a column is buried in the ground, and a column for supporting the fixture is supported on this support member for a column, so that the column is disposed in a standing state on the ground. Then, the fixture is fixed to the column.
[0003] Patent Document 1 discloses a precast concrete block for installing columns such as road signs, curve mirrors, and guardrails, which includes a block body having a column fixing hole into which the column is inserted on the upper surface, and an extended bottom plate extending in the lateral direction below the block body.
[0004] Japanese Patent Application Laid-Open No. 2006-299530
[0005] However, the concrete block for column fixing has a problem in that its weight is large, and a great burden is imposed on the operator during the transportation of the concrete block for column fixing and the embedding work at a predetermined location.
[0006] In order to solve the above problems, the present invention provides a divided body that can constitute a support member for a column by combining a plurality of them and integrating them, and a method for installing a column using the divided body. <00The divided body of the present invention is a divided body for assembling a support member for a support column to support the base end of the support column and fix the support column in an upright position on the ground, wherein the divided body is formed by combining a plurality of divided bodies, and a support column holding portion for holding the base end of the support column is formed between the combined divided bodies.
[0009] The support member for the support column of the present invention is characterized by being constructed by combining a plurality of the aforementioned divided parts.
[0010] The present invention provides a method for installing a support column, comprising the steps of: manufacturing a support column holding member by combining a plurality of divided bodies, wherein a support column holding portion for holding the base end of the support column is formed between the divided bodies; forming a buried hole in a construction surface where the support column will be erected, for burying the support column holding member; arranging the support column holding member in the buried hole and arranging the support column in an upright position on the support column holding portion of the support column holding member; and supplying a filler material into the support column holding portion of the support column support member and fixing the support column in an upright position in the buried hole.
[0011] The divided parts of the present invention constitute a support member for a support column by combining multiple parts, and a support column holding part for holding the base end of the support column is formed between the combined divided parts. Therefore, the divided parts of the support member for a support column are lightweight. Consequently, the divided parts can be easily transported, and the assembly of the support member for a support column using the divided parts can be carried out by a small number of workers, thereby improving work efficiency.
[0012] Furthermore, since the support member of the support column is constructed by combining multiple segmented parts, even if stress is applied to the support member of the support column due to an earthquake or the like while it is embedded and fixed in the buried hole, the stress applied to the support member can be absorbed by the deformation at the connection points between the segmented parts, thereby reducing damage to the support member of the support column and enabling stable support of the column.
[0013] The above-described segmented body includes a segmented wall portion that constitutes a part of the wall portion of the support member of the support column, a first connecting portion formed at one end of the segmented wall portion, and a second connecting portion formed at the other end of the segmented wall portion and connectable to the first connecting portion. In this case, two adjacent segmented bodies can be directly connected and integrated by connecting the first connecting portion of one segmented body to the second connecting portion of the other segmented body. Therefore, there is no need to separately prepare adapters for connecting multiple segmented bodies, and the segmented bodies can be brought to the site where the support column is erected to easily form the support member of the support column.
[0014] In the above-mentioned divided body, if the divided wall portion of the divided body has a filling recess on its outer surface that is recessed inward, the filling material filled on the outside of the support member of the support column formed by assembling the divided body can be filled into the filling recess, and the support member of the support column can be fixed firmly and securely in the buried hole formed in the ground by the anchor effect.
[0015] In the above-mentioned divided body, if the bottom of the filling recess formed in the divided wall portion of the divided body forms the column holding portion, the weight of the divided body is reduced by having the bottom of the filling recess share a part of the column holding portion.
[0016] The above-mentioned divided body has a plurality of base wall sections, each having a first filling recess and connected at a predetermined angle, and a second filling recess formed at the connection portion between the base wall sections, which connects and integrates the first filling recesses of the base wall sections. In this case, by connecting and integrating the filling material filled in the first filling recess of each base wall section via the second filling recess, the support member of the support column can be fixed from the outside with the integrated filling material, and the support member of the support column can be firmly fixed in the buried hole formed in the ground.
[0017] In the above-mentioned divided body, if a filler material flow port is formed in the divided wall portion of the divided body, connecting the outside of the divided body to the support column holding portion and allowing the filler material to flow through, the filler material filled on the outside of the support member of the support column and the filler material filled inside the support column holding portion can be joined and integrated through the filler material flow port, thereby firmly fixing the support member of the support column.
[0018] Furthermore, the filling pressure of the filler material filled on the outside of the support column and the filling pressure of the filler material filled inside the support column holder can be made approximately equal, minimizing the pressure applied from the filler material filled in the buried hole to the segmented parts constituting the support member of the support column. This reduces the risk of damage to the support member of the support column when it is buried and fixed in the buried hole.
[0019] In the above-mentioned divided body, the divided wall portion of the divided body has a protruding portion that extends outward, and when the filler material flow port is formed in the protruding portion, the protruding portion is formed within a filler recess formed on the outer surface of the divided body. As a result, an uneven surface is formed on the outer surface of the support member of the support column, which can further improve the anchoring effect of the filler material and allow the support member of the support column to be fixed more firmly in the buried hole.
[0020] Furthermore, since a filler material flow port is formed in the protruding portion, the filler material filled inside and outside the support member of the column is joined and integrated through the filler material flow port in the protruding portion. During this joining and integration process of the filler material, the protruding portion is securely surrounded and fixed by the filler material, and thus the support member of the column is more firmly fixed within the buried hole.
[0021] The support member of the column is constructed by combining multiple of the divided parts, each divided part having a divided wall portion that forms part of the wall portion of the support member of the column, a first connecting portion formed at one end of the divided wall portion, and a second connecting portion formed at the other end of the divided wall portion and connectable to the first connecting portion, with adjacent divided parts having the first connecting portion of one divided part and the second connecting portion of the other divided part connected and integrated. In this case, the support member of the column can be manufactured by combining one type of divided part, the divided parts can be easily transported to the work site, there is no need to combine multiple parts, and the formation of the support member of the column can be carried out smoothly and without hassle.
[0022] Since the support members for the support columns can be formed from a single type of segmented material, it is sufficient to manage only one type of segmented material in the storage area, thereby saving storage space and making it easier to manage the storage of the segmented material.

[0024] An example of a segmented part of the present invention used to constitute a support member for a support column will be described with reference to the drawings.
[0025] As shown in Figures 1 to 3, the divided body 1 has a divided wall portion 2 that constitutes a part of the wall portion A2 of the support member A of a support column assembled by connecting a plurality of divided bodies 1, a first connecting portion 21 formed at one end of the divided wall portion 2, and a second connecting portion 22 formed at the other end of the divided wall portion 2 and connectable to the first connecting portion 21.
[0026] The divided wall portion 2 of the divided body 1 has two base wall portions 23a and 23b that intersect at right angles to each other and are connected and integrated. The base wall portions 23a and 23b of the divided body 1 have a height and width that can stably hold the base end of the support column P that is supported by the support member A of the support column which is formed by combining the divided bodies 1 and 1. Note that the base wall portions 23a and 23b constituting the divided wall portion 2 of the divided body 1 do not have to intersect at right angles, and may be connected and integrated at any angle.
[0027] The divided wall portion 2 of the divided body 1 constitutes a part of the wall portion A2 of the support member A of the column, which is formed by combining the divided bodies 1, 1. The divided wall portion 2 of the divided body 1 is constructed by connecting and integrating two base wall portions 23a and 23b with their opposing ends. The two base wall portions 23a and 23b have a symmetrical structure except that a first connecting portion 21 is formed at one end of one base wall portion 23a and a second connecting portion 22 is formed at the other end of the other base wall portion 23b. However, the base wall portion of the divided body does not necessarily have to have a symmetrical structure.
[0028] The base wall portions 23a and 23b are formed in a rectangular shape on the front, and the portions excluding the upper and lower ends on the outer surface are recessed inward to form filling recesses 24a and 24b. The inside of the divided body 1 is defined as the direction toward the column holding portion A1 when multiple divided bodies 1 are combined to form the support member A of the column, and the outside is the direction facing the embedded hole in the support member A of the column.
[0029] The first filling recesses 24a and 24b of the base wall portions 23a and 23b of the divided body 1 have a front rectangular bottom portion 241a and 241b, and peripheral wall portions 242a and 242b that are integrally formed around the entire circumference of the four outer edges of the bottom portion 241a and 241b and gradually widen diagonally outward. The peripheral wall portions 242a and 242b of the first filling recesses 24a and 24b share the first peripheral wall portion 2421 as a connection portion between the base wall portions 23a and 23b, and have second peripheral wall portions 242a2 and 242b2 connected to and integrated with the upper end of the first peripheral wall portion 2421, third peripheral wall portions 242a3 and 242b3 connected to and integrated with the lower end of the first peripheral wall portion 2421, and fourth peripheral wall portions 242a4 and 242b4 connecting and integrating the second peripheral wall portions 242a2 and 242b2 and the third peripheral wall portions 242a3 and 242b3. The peripheral wall portions 242a and 242b of the first filling recesses 24a and 24b of the divided body 1 have bottom portions 241a and 241b, and first peripheral wall portions 2421, second peripheral wall portions 242a2 and 242b2, third peripheral wall portions 242a3 and 242b3, and fourth peripheral wall portions 242a4 and 242b4 which are connected and integrated with the four outer peripheral edges of the bottom portions 241a and 241b. The first filling recesses 24a and 24b of the base wall portions 23a and 23b of the divided body 1 are formed in a truncated square pyramidal shape that is fully open outward and gradually becomes smaller inward.
[0030] The first peripheral wall portion 2421 of the peripheral wall portions 242a and 242b, which form the first filling recesses 24a and 24b of the base wall portions 23a and 23b, has a second filling recess 27 formed on its outer surface that is recessed inward. Alternatively, the second filling recess 27 may be formed by recessing the entire first peripheral wall portion 2421 inward.
[0031] The first filling recesses 24a and 24b of the base wall portions 23a and 23b are connected and integrated via a second filling recess 27 formed in the connecting portion (first peripheral wall portion 2421) of the base wall portions 23a and 23b. On the outer surface of the base wall portions 23a and 23b, a third filling recess 29 is formed by the first filling recesses 24a and 24b and the second filling recess 27, covering the entire surface except for the upper and lower ends. In the divided body 1, when simply referred to as "filling recess," it means one or more of the first filling recesses 24a and 24b, the second filling recess 27, and the third filling recess 29.
[0032] At one end of the divided wall portion 2, specifically at the upper and lower parts of the fourth peripheral wall portion 242a4 of the first filling recess 24a in the base wall portion 23a of the divided wall portion 2, first connecting portions 21, 21 are provided, which bulge out in a truncated square pyramidal shape from the outside inward, becoming slightly smaller towards the tip.
[0033] On the other hand, at the other end of the divided wall portion 2, that is, at the upper and lower parts of the fourth peripheral wall portion 242b4 of the first filling recess 24b in the base wall portion 23b of the divided wall portion 2, a rectangular second connecting portion 22, 22 is formed that penetrates in the inward and outward direction and into which the first connecting portions 21, 21 can be inserted and connected.
[0034] As shown in Figure 4, with respect to the two divided bodies 1, 1, when the end of the base wall portion 23a of the divided wall portion 2 of one divided body 1 and the end of the base wall portion 23b of the divided wall portion 2 of the other divided body 1 are positioned opposite each other, the first connecting portions 21, 21 of one divided body 1 are inserted into the second connecting portions 22, 22 of the other divided body 1 and connected, so that the upper and lower first connecting portions 21, 21 formed at one end of the divided wall portion 2 are permanently connected and integrated with the upper and lower second connecting portions 22, 22 formed at the other end of the divided wall portion 2. Multiple locking pieces 211 are provided protruding from the outer circumferential surface of the first connecting portion 21, and when this first connecting portion 21 is inserted into the second connecting portion 22, the locking pieces 211 of the first connecting portion 21 are permanently locked to the open end edge of the second connecting portion 22.
[0035] Multiple protruding portions 25 are formed on the base wall portions 23a and 23b of the divided wall portion 2, with a portion of each portion projecting outward in a planar V-shape, arranged vertically at predetermined intervals. The protruding portions 25 are formed by bending a plate-like body in its central part to create a planar V-shape. The protruding portions 25 are constructed by connecting and integrating protruding pieces 25a, 25a, which gradually narrow in the vertical direction from the inside outward, at their outer ends. Filling material flow openings 251, 251 are formed between the upper and / or lower edges of the protruding portions 25 and the base wall portions 23a and 23b facing these edges. The protruding portions 25 may have other shapes besides the planar V-shape, such as a planar U-shape, as long as they can form the filling material flow openings 251, 251.
[0036] In the divided body 1 shown in Figures 1-3, the upper protrusion 25 has filler flow ports 251, 251 formed at its upper and lower ends, and the lower protrusion 25 has filler flow ports 251, 251 formed at its upper end. In the divided body 1 shown in Figures 1-3, the lower protrusion 25 has its lower end connected and integrated onto the third peripheral wall portions 242a3, 242b3 of the first filling recesses 24a, 24b. The lower protrusion 25 has a filler flow port 251 formed only at its upper end. Alternatively, the lower protrusion 25 may be formed such that its lower end is above the third peripheral wall portions 242a3, 242b3 of the first filling recesses 24a, 24b, and filler flow ports 251, 251 may be formed at its upper and lower ends in the same way as the upper protrusion 25. Through the filler material flow opening 251 of the protruding portion 25, the inside and outside of the base wall portions 23a and 23b are connected and communicate with each other, that is, the column holding portion A1 of the column support member A formed by assembling the divided body 1 and the space outside the column support member A.
[0037] The filler material flow ports 251, 251 formed above and below the protruding portion 25 are arranged vertically, and the filler material D supplied into the support member A1 of the support column is configured to flow smoothly from the filler material flow ports 251, 251 of the protruding portion 25 into the embedded hole B on the outside of the support member A of the support column. The phrase "the filler material flow ports 251, 251 formed above and below the protruding portion 25 are arranged vertically" means that when the vertically adjacent filler material flow ports 251, 251 are projected onto each other in the vertical direction (the direction in which the filler material flow ports are aligned), the filler material flow ports 251, 251 partially or completely overlap each other.
[0038] Since the filler material flow ports 251, 251 of the protruding portion 25 are formed in an orderly fashion, the air in the buried hole B that is pushed out by the filler material D filled in the support member A of the support column can move smoothly upward through the vertically aligned filler material flow ports 251, 251, allowing the air in the buried hole B to be smoothly removed while the filler material D is filled into the buried hole B almost without any gaps, and the support member A of the support column can be fixed stably and firmly into the buried hole B.
[0039] Alternatively, the filler material flow opening may be a through-hole formed in the wall surface that forms the support column holding portion A1 of the divided body 1, with the through-hole penetrating in the inward and outward directions. Specifically, a through-hole may be formed in the base wall portions 23a and 23b of the divided body 1 (preferably the first filling recesses 24a and 24b), with the through-hole penetrating in the inward and outward directions, and the filler material flow opening may be a through-hole. The number of filler material flow openings may be one or more. The shape of the filler material flow opening is not particularly limited and can be circular, polygonal, slit-shaped, etc.
[0040] A mounting portion 26 is formed at the upper end of the dividing wall portion 2 of the divided body 1, on which another divided body 1 can be placed. The mounting portion 26 of the divided body 1 is formed by the upper ends of the base wall portions 23a and 23b of the dividing wall portion 2 and the second peripheral wall portions 242a2 and 242b2 of the first filling recesses 24a and 24b.
[0041] On the other hand, the lower end of the divided wall portion 2 of the divided body 1 has stepped portions 23a1 and 23b1 formed thereon, to which the mounting portion 26 of the upper divided body 1 can be connected. More specifically, the lower end of the divided wall portion 2 of the divided body 1 is recessed inward from its lower end, via stepped portions 23a1 and 23b1, by the thickness of the upper ends of the base wall portions 23a and 23b, in a portion that matches the vertical height of the mounting portion 26 (a portion that matches the vertical height of the upper ends of the base wall portions 23a and 23b that form the mounting portion 26 of the divided body 1).
[0042] As shown in Figure 5, the lower ends of the base wall portions 23a, 23b of the divided body 1, 1 constituting the support member A of the upper support column are placed on the second peripheral wall portions 242a2, 242b2 of the mounting portions 26, 26 of the divided body 1, 1 constituting the support member A of the lower support column. Then, the stepped portions 23a1, 23b1 of the upper divided body 1 are received by the support portions 261, 261 of the lower divided body 1, which will be described later, and the two support members A, A of the support columns can be connected vertically and used. Alternatively, the upper end of the divided wall portion 2 of the lower divided body 1 may be configured to receive the stepped portions 23a1, 23b1 of the upper divided body 1.
[0043] The second circumferential wall portions 242a2 and 242b2 of the first filling recesses 24a and 24b in the base wall portions 23a and 23b of the divided body 1 are inclined downward toward the inward direction. On the other hand, the lower ends of the base wall portions 23a and 23b of the divided body 1 are formed horizontally across their entire surface, so support portions 261, 261 are provided projecting upward from the upper end surfaces of the second circumferential wall portions 242a2 and 242b2 of the first filling recesses 24a and 24b to support the lower ends of the upper base wall portions 23a and 23b of the divided body 1 in a horizontal position.
[0044] At the upper ends of the base wall portions 23a and 23b that form the placement portion 26 of the divided body 1, locking holes 23a2 and 23b2 penetrating in the inner and outer directions are formed. On the other hand, at the lower ends of the outer surfaces of the base wall portions 23a and 23b of the divided body 1 placed on the upper side, locking pieces 23a3 and 23b3 are formed. When the support members A of the columns composed of the divided bodies 1, 1 are stacked vertically, the locking pieces 23a3 and 23b3 of the divided body 1 constituting the upper support member A of the column are locked in a non-removable state to the locking holes 23a2 and 23b2 of the divided body 1 constituting the lower support member A of the column, and the support members A, A of the column are configured to be vertically stacked and integrated.
[0045] At the connection portion of the base wall portions 23a and 23b of the divided body 1 (the inner portion of the corner portion of the dividing wall portion 2), specifically, at the connection portion of the second peripheral wall portions 242a2 and 242b2 of the first filling recesses 24a and 24b in the base wall portions 23a and 23b, a placement recess 4 for disposing the temporary fixing member 3 is formed in a state of being entirely open upward and inward by recessing downward over the entire length in the inner and outer directions. The bottom surface 41 of the placement recess 4 is formed on a receiving surface for receiving the shaft body 31 of the temporary fixing member 3. The bottom surface 41 of the placement recess 4 may be formed on a horizontal plane or on an inclined surface inclined inward.
[0046] As shown in Fig. 6, the temporary fixing member 3 has a shaft body 31 of a certain length and a strut contact portion 32 formed at the tip of the shaft body 31. Rotation shafts 311 and 311 project from both side surfaces of the base end portion of the shaft body 31 of the temporary fixing member 3, and support holes capable of rotatably supporting the rotation shafts 311 and 311 of the shaft body 31 of the temporary fixing member 3 are formed on both side wall surfaces of the recess 4 for arrangement. The temporary fixing member 3 is supported so as to be able to undulate and rotate in the vertical direction about its base end portion. In addition, at the connection portion of the third peripheral wall portions 242a3 and 242b3 of the first filling recesses 24a and 24b in the base wall portions 23a and 23b, a recess 2331 that is recessed upward over the entire length in the inner and outer directions and is entirely open inward and downward is formed. Even when another support member A of a strut is placed on the placement portion 26 of the split body 1 that constitutes the support member A of the strut, the shaft body 31 of the temporary fixing member 3 is configured to be able to enter the recess 2331. The rotation shafts 311 and 311 of the shaft body 31 of the temporary fixing member 3 are supported on both side wall surfaces of the recess 4 for arrangement so that the temporary fixing member 3 can rotate freely up and down about its base end portion.
[0047] In a state where the shaft body 31 of the temporary fixing member 3 is housed in the recess 4 for arrangement, the strut contact portion 32 is arranged in the strut holding portion A1 of the strut support member A formed by combining the split bodies 1 and 1. On the other hand, by rotating the temporary fixing member 3 in the direction of standing up about its base end, the interval between the strut contact portions 32 and 32 of the opposing temporary fixing members 3 and 3 can be increased, and the interval between the strut contact portions 32 and 32 of the temporary fixing members 3 and 3 can be adjusted according to the size of the strut P held in the strut holding portion A1 of the strut support member A.
[0048] In addition, in Figs. 1 to 5, the case where the temporary fixing member 3 is arranged on the split body 1 is shown, but the temporary fixing member 3 may not be arranged. The strut contact portion 32 of the temporary fixing member 3 only needs to be able to temporarily fix the strut stably, and is not limited to the above structure.
[0049] The divided body 1 and the temporary fixing member 3 may be formed from any material. Examples of materials include synthetic resins and metals (e.g., iron, copper, aluminum, alloys, etc.), with synthetic resins being preferred. The synthetic resin may be a thermoplastic resin, a thermosetting resin, or a photocurable resin. Reinforcements and fillers may be included in each of the divided body 1 and the temporary fixing member 3.
[0050] Next, the procedure for using the divided body 1 will be explained. The divided body 1 can be used to form a support member A for a single support column by combining two divided bodies 1, 1.
[0051] Specifically, two divided bodies 1, 1 are prepared. As shown in Figure 4, the two divided bodies 1, 1 are arranged so that their first filling recesses 24a, 24b face outwards, and the first connecting portions 21, 21 and second connecting portions 22, 22 of one divided body 1 face the second connecting portions 22, 22 and first connecting portions 21, 21 of the other divided body 1.
[0052] Next, the first connecting parts 21, 21 of the divided parts 1, 1 are inserted into the second connecting parts 22, 22 and locked in a non-removable state, thereby integrating the two divided parts 1, 1 to create the support member A for the support column (Figure 7). Multiple divided parts 1 can be brought to the construction site for the support member A for the support column, and since the divided parts 1 are lighter than the support member A for the support column, transportation from the storage location to the construction site can be easily carried out.
[0053] Furthermore, as shown in Figure 9, the divided body 1 can be placed upright by rotating the temporary fixing member 3 upward around its base end, and then multiple divided bodies 1 can be stacked vertically with their first filling recesses 24a and 24b facing upwards. Multiple divided bodies 1 can be stacked vertically by detachably fitting the protruding portions of the first filling recesses 24a and 24b of the upper divided body 1 into the recesses of the first filling recesses 24a and 24b of the lower divided body 1. The protruding portions 25 of the first filling recesses 24a and 24b of the lower divided body 1 are detachably fitted into the protruding portions 25 of the first filling recesses 24a and 24b of the upper divided body 1. The first connecting portion 21 of the upper divided body 1 is detachably fitted into the first connecting portion 21 of the lower divided body 1. The divided parts 1 can be stacked neatly to reduce the overall volume, thereby saving storage space.
[0054] The support member A of the support column, formed by integrating two divided bodies 1, 1, has a support column holding portion A1 that penetrates vertically through the space between the opposing surfaces of the divided bodies 1, 1, that is, the space enclosed by the bottom portions 241a, 241b of the first filling recesses 24a, 24b.
[0055] At the upper part (upper end) of the support member A of the support column, a pair of temporary fixing members 3, 3 are arranged facing each other, sandwiching the support column P which is held by the support column holding portion A1 of the support member A of the support column.
[0056] A pair of temporary fixing members 3, 3 are arranged with their entire shaft 31 in a horizontal position and housed in the mounting recess 4, with the column contact portions 32 positioned facing each other within the column holding portion A1 of the column support member A. The temporary fixing member 3 is configured to be rotated upward around the base end of its shaft 31, thereby widening the distance between the column contact portions 32, 32 of a pair of temporary fixing members 3, 3 according to the size of the column P. A pair of temporary fixing members 3, 3 supports and temporarily fixes the column P by bringing their column contact portions 32 into contact with the column portion disposed at the upper end opening of the column holding portion A1 of the column support member A, or with the column portion protruding upward from the column holding portion A1.
[0057] The above describes a case in which two divided parts 1 are combined to create a support member A for one support column. However, it is also possible to prepare two support members A for the support column formed as described above, and place the lower ends of the rectangularly combined base wall parts 23a, 23b, etc. of the divided parts 1, 1 that constitute the lower support member A on the second peripheral wall parts 242a2, 242b2, etc. of the rectangularly combined mounting parts 26, 26 of the divided parts 1, 1 that constitute the lower support member A for the support column, thereby connecting and integrating the two support members A, A vertically.
[0058] Meanwhile, at the construction site where the support column P will be erected, a burial hole B is formed in the ground for burying the support member A of the support column [Figure 8(a)]. The burial hole B is deep enough to bury the support member A of the support column along its entire vertical length. Gravel C or the like is laid in the burial hole B as needed [Figure 8(b)].
[0059] Next, the support member A of the support column is placed in an upright position within the buried hole B [Figure 8(c)]. If the support column contact portion 32 of the temporary fixing member 3 is placed within the upper end opening of the support column holding portion A1 of the support member A of the support column placed in the buried hole B, the temporary fixing member 3 is rotated upward using its base end as a pivot point to be in an upright position, and the upper end opening of the support column holding portion A1 of the support member A of the support column is opened.
[0060] Subsequently, the support column P, which is to be fixed upright on the ground, is inserted into the support column holding portion A1 of the support member A of the support column from the upper end opening, and the lower end of the support column P is positioned so that it is supported by the inner bottom surface of the buried hole B. The temporary fixing member 3 of the support member A of the support column is rotated downward with its base end as a pivot point, and the base end of the support column P is temporarily fixed by supporting it from both sides with the support column contact portion 32 of the temporary fixing member 3 [Figure 8(d)]. Since the support column P is supported in an upright position by the temporary fixing members 3, 3, the worker does not need to constantly support the support column P to maintain its upright position, thus reducing the number of workers or alleviating their burden.
[0061] Furthermore, when the support column is in an upright position, the angle of the column with respect to the surface on which it is installed does not need to be perpendicular; it may be inclined with respect to the surface. For example, if the surface on which the support column is installed is an inclined surface, the angle may be perpendicular to the inclined surface or vertical.
[0062] A filler material D is supplied into the support member A of the support column. Since the support column holding portion A1 of the support member A of the support column penetrates vertically, the filler material D is sequentially filled from the bottom of the buried hole B, and the filler material D can be firmly integrated with the buried hole B. A known material can be used as the filler material D, such as mortar, cement, asphalt, or soil.
[0063] Multiple filler material flow ports 251 of the protruding portion 25 of the divided body 1 are formed on the inner wall surface of the column holding portion A1 of the column support member A. The filler material D supplied into the column holding portion A1 flows out to the outside of the column support member A, that is, into the space formed between the opposing surfaces of the column support member A and the embedded hole B, and this space is filled with the filler material D [Figure 8(e)].
[0064] The first filling recesses 24a and 24b of the divided body 1 are formed as recesses that face inward, while the protrusions 25 formed in the first filling recesses 24a and 24b of the divided body 1 are formed as protrusions that face outward. The filling material D flows out from the support column holding part A1 to the outside of the support member A of the support column through the filling material flow port 251 of the protrusion 25. Therefore, the filling material D flows into the first filling recesses 24a and 24b of the divided body 1 while enveloping the protrusion 25 (enclosing the protrusion 25 inside).
[0065] The first filling recesses 24a and 24b formed in the base wall portions 23a and 23b of the divided wall portion 2 of the divided body 1 are connected via the second filling recess 27 at the corner of the divided wall portion 2. Therefore, the divided body 1, which constitutes the support member A of the support column, is embedded in the filling material D, surrounded by the filling material D filled in the first filling recesses 24a and 24b and the second filling recess 27 (i.e., the third filling recess).
[0066] Furthermore, in the divided wall portion 2 of the divided body 1 that constitutes the support member A of the support column, a protruding portion 25 is formed to protrude outward within first filling recesses 24a and 24b that are recessed inward. The wall portion A2 of the support member A of the support column is formed by the divided wall portions 2 and 2 of the divided body 1 and 1. The divided wall portion 2 has large irregularities formed by the first filling recesses 24a and 24b and the protruding portion 25, and the protruding portion 25 is surrounded by the filling material. The support member A of the support column is then installed and fixed in the buried hole B with the filling material D firmly holding it in place by the anchoring effect.
[0067] Furthermore, the inside and outside of the column holding portion A1 of the column support member A are separated by the first filling recesses 24a and 24b. Although pressure is applied inward and outward from the filler material D to the bottom portion and the first to fourth peripheral wall portions 24a1 to 24a4 and 24b1 to 24b4 that constitute the first filling recesses 24a and 24b, these pressures are largely canceled out, so the divided body 1 does not receive significant pressure from the filler material D. The divided body 1 is positioned and fixed in the buried hole B without causing much distortion, and can maintain a stable support for the column P over a long period of time.
[0068] Filler material D is filled into the column holding portion A1 of the column support member A and into the space formed between the opposing surfaces of the column support member A and the buried hole B. The column support member A is firmly embedded and fixed in the buried hole B with the base end of the column P firmly held within its column holding portion A1, and the column P is fixed in an upright position with the remaining portion, excluding its base end, protruding from the ground.
[0069] In the above-described divided body 1, the case in which a temporary fixing member 3 is placed in the placement recess 4 was explained, but as shown in Figure 10, the temporary fixing member 3 does not have to be provided. In Figure 10, the bottom surface 41 of the placement recess 4 of the divided body 1 is formed as an inclined surface that slopes downward from the outside to the inside. Note that, except for the fact that the bottom surface 41 of the placement recess 4 of the divided body in Figure 10 is formed as an inclined surface, the divided body in Figure 10 has the same shape as the divided body 1 shown in Figures 1 and 2, so the same reference numerals are used and the explanation is omitted.
[0070] In the divided body 1, a groove 28 extending in the vertical direction is formed, connecting the inner opening end of the mounting recess 4 and the inner opening end of the recess 2331. The groove 28 of the divided body 1 is formed to fully open into the support column holding portion A1 of the support member A of the support column, which is formed by combining the divided body 1, 1.
[0071] Therefore, the filler material D can be supplied into the column holding portion A1 of the column support member A through the bottom surface 41 and groove 28 of the placement recess 4, and the filler material D can be easily filled into the column holding portion A1 of the column support member A.
