Summary of the Invention

Problem to be Solved by the Invention

[0005] However, in order to cause the concrete block for fixing posts to support a post, the post is inserted in an upright state into the post fixing hole of the block body, and while one worker holds the post in this upright state, another worker fills a filler such as mortar or cement into the post fixing hole of the block body, which has the problem that a large number of workers are required.

[0006] Furthermore, workers must hold the support column and wait for the filling material, which is placed in the support column fixing holes of the block body, to harden to a degree that allows it to support the column. During this time, other tasks cannot be performed, which leads to a decrease in work efficiency.

[0007] The present invention provides a support member for a support column that allows the erection of the support column to be carried out by a small number of workers, eliminates the need to wait for the filling material to harden, and enables efficient erection of the support column, as well as a method for installing a support column using this support member. [Means for solving the problem]

[0008] The support member for the column of the present invention is A support member body having a support column holding portion that holds the base end of a support column fixed in an upright position on the ground, The support member is characterized by having a temporary fixing member disposed in the opening of the column holding portion of the main support member body and for temporarily fixing the column.

[0009] The method for installing support columns according to the present invention is: The process involves burying a support member for a support column, which has a support member body having a support column holding portion for holding the base end of the support column, and a temporary fixing member disposed in the opening of the support column holding portion of the support member body and for temporarily fixing the support column, by forming a burying hole in the construction surface where the support column will be erected, The process involves placing the support member for the support column in the buried hole, placing the base end of the support column in the support column holding portion of the support member, and temporarily fixing the support column by supporting the base end of the support column with the temporary fixing member, The method is characterized by including the step of supplying a filler material into the column-holding portion of the support member of the column, and fixing the column in an upright position in the buried hole. [Effects of the Invention]

[0010] The support member for the support column of the present invention has a temporary fixing member on the main body of the support member for temporarily fixing the support column. As a result, the support column placed within the support column support section can be temporarily fixed by the temporary fixing member, eliminating the need to manually support the support column before and after filling the support member or the buried hole with filler material. This allows for the smooth erection of the support column on the ground with a small number of workers.

[0011] Furthermore, since no support work is required for the support column after filling the support member or buried hole with filler material, workers can perform other tasks such as erecting other support columns, thereby improving work efficiency.

[0012] In the support member for the support column described above, if the temporary fixing member is disposed at the upper end of the support member body so as to be able to move up and down, the positional relationship between the temporary fixing member and the support column can be adjusted by adjusting the degree of uprightness of the temporary fixing member according to the size of the support column supported by the support column holding part, and the support column can be stably supported by the temporary fixing member in an optimal state.

[0013] The support member for the above-mentioned support column has a set of temporary fixing members, which are arranged facing each other on either side of the support column. In this case, the support column, which is positioned in the support column holding portion of the support member body, can be securely temporarily fixed by the temporary fixing members, and the support column can be stably fixed to the ground in an upright position.

[0014] In the support member for the support column described above, the temporary fixing member has a shaft whose base end is rotatably supported by the support member body, and a support column contact portion formed at the tip of the shaft, and the support column contact portion has a pair of support parts formed at the tip of the shaft and extending toward the support column and held by the support column holding portion of the support member body, and an elastic piece formed at the tip of the support parts and having a free end at the tip which is curved toward the support column in a convex arc shape, the elastic piece can be elastically deformed in a way that allows it to return to its original shape according to the size of the support column, thereby securely gripping the support column.

[0015] The column contact portion of the temporary fixing member has a resilient piece that curves in a convex arc shape toward the column, with the tip being a free end. Regardless of the vertical upright angle with its base end as the pivot point, the temporary fixing member can reliably hold the column by elastically deforming when the resilient piece contacts the column.

[0016] In the support member for the support column described above, the temporary fixing member has a shaft whose base end is rotatably supported by the support member body and which has a filler material receiving portion formed on its upper surface, and a support column contact portion formed at the tip of the shaft. In this case, when filler material is supplied into the support member body, the filler material is filled into the filler material receiving portion of the shaft of the temporary fixing member, and the weight of this filler material causes the temporary fixing member to rotate in a downward direction (downward) with its base end as a fulcrum, thereby improving the support force of the support column by the temporary fixing member, and allowing the support column to be held more securely by the temporary fixing member.

[0017] In the support member of the above-mentioned support column, if the support member body is composed of multiple divided parts, the divided parts of the support member body are lightweight. Therefore, the divided parts can be easily transported, and the assembly of the support member body using the divided parts can be carried out by a small number of workers, thereby improving work efficiency.

[0018] Furthermore, since the support member body is constructed by combining multiple segmented parts, even if stress is applied to the support member body due to an earthquake or the like while it is embedded and fixed in the buried hole, the stress applied to the support member body can be absorbed by the deformation at the connection points between the segmented parts, thereby reducing damage to the support member body and enabling stable support of the column.

Mode for Carrying Out the Invention

[0020] An example of the support member for a support column according to the present invention will be described with reference to the drawings. Description will be given by taking, as an example, a case where a support member main body A in the support member G for a support column is configured by combining a plurality of divided bodies 1, 1.

[0021] As shown in FIGS. 1 to 3, the divided body 1 includes: a divided wall portion 2 that constitutes a part of a wall portion A2 of the support member main body A assembled by connecting a plurality of the divided bodies 1; a first connection portion 21 formed at one end of the divided wall portion 2; and a second connection portion 22 formed at the other end of the divided wall portion 2 and connectable to the first connection portion 21.

[0022] The divided wall portion 2 of the divided body 1 has two base wall portions 23a, 23b that intersect each other at a right angle and are connected and integrated. The base wall portions 23a, 23b of the divided body 1 have a height and a width that allow stably holding the base end portion of the support column P supported by the support member main body A in the support member main body A configured by combining the divided bodies 1, 1. Note that the base wall portions 23a, 23b constituting the divided wall portion 2 of the divided body 1 do not need to intersect at a right angle, and may be connected and integrated at any angle.

[0023] The divided wall portion 2 of the divided body 1 constitutes a part of the wall portion A2 of the support member body A, 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 portions of the divided body do not necessarily have to have a symmetrical structure.

[0024] The base wall portions 23a and 23b are formed in a rectangular shape on the front, and the filling recesses 24a and 24b are formed by recessing the portions on the outer surface, excluding the upper and lower ends, inward. The inside of the divided body 1 is defined as the direction toward the support member body A when multiple divided bodies 1 are combined to form the support member body A, and the direction facing the embedded hole in the support member body A is defined as the outside.

[0025] The 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 filling recesses 24a and 24b share the first peripheral wall portion 2421 at the connection portion of 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 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.

[0026] The first peripheral wall portion 2421 of the peripheral wall portions 242a and 242b, which form the filling recesses 24a and 24b of the base wall portions 23a and 23b, is recessed inward at the outer surface of the corner of the connection portion between the base wall portions 23a and 23b of the divided body 1, forming a filling recess 27. The filling recesses 24a and 24b of the base wall portions 23a and 23b are connected and integrated via the filling recesses 27 formed at the connection portion of the base wall portions 23a and 23b, and the filling recesses 24a, 24b and 27 are formed all over the outer surface of the base wall portions 23a and 23b, except for their upper and lower ends.

[0027] 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 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.

[0028] 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 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.

[0029] As shown in Figure 4, with two divided bodies 1, 1, 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 divided wall portion 2 of the other divided body 1 are positioned opposite each other, and 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 to connect them. The upper and lower first connecting portions 21, 21 formed at one end of the divided wall portion 2 are then 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.

[0030] 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, and spaced at predetermined intervals vertically. 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.

[0031] In the divided body 1 shown in Figures 1-3, the upper protrusion 25 has filler flow ports 251, 251 at its upper and lower ends, and the lower protrusion 25 has filler flow ports 251, 251 at its upper end. In the divided body 1 shown in Figures 1-3, the lower protrusion 25 is formed so that its lower end aligns with the lower ends of the bottom surfaces 241a, 241b of the filling recesses 24a, 24b, and the lower protrusion 25 has a filler flow port 251 only at its upper end. However, the lower protrusion 25 may be formed so that its lower end is above the lower ends of the bottom surfaces 241a, 241b of the 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 the support column holding portion A1 of the support member body A formed by assembling the divided body 1 and the space outside the support member body A.

[0032] 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 column holding portion A1 of the support member body A 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 body A.

[0033] 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 column holding portion of the support member body A 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 G of the column can be fixed stably and firmly into the buried hole B.

[0034] Alternatively, the filler material flow opening may be a through-hole formed in the wall surface of the support member body A or the 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, 23b or the filling recesses 24a, 24b of the divided body 1, 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 may be circular, polygonal, slit-shaped, etc.

[0035] 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 filling recesses 24a and 24b.

[0036] On the other hand, the lower end of the divided wall portion 2 of the divided body 1 is formed by recessing it inward via stepped portions 23a1 and 23b1 by the thickness of the upper ends of the base wall portions 23a and 23b, which form the mounting portion 26 of the divided body 1, at a height that matches the vertical height of the upper ends of the base wall portions 23a and 23b from its lower end.

[0037] As shown in Figure 5, the two support members G, G for the upper support column can be connected vertically by placing the lower ends of the base wall portions 23a, 23b of the divided bodies 1, 1 that constitute the support member body A of the divided bodies 1, 1 that constitute the support member body A of the lower support column on the second peripheral wall portions 242a2, 242b2 of the mounting portions 26, 242b2 of the divided bodies 1, 1 that constitute the support member body A of the lower support column.

[0038] The second circumferential wall portions 242a2 and 242b2 of the filling recesses 24a and 24b in the base wall portions 23a and 23b of the divided body 1 are gradually inclined downward from the connection point between the base wall portions 23a and 23b toward the end. On the other hand, the lower ends of the base wall portions 23a and 23b of the divided body 1 are formed horizontally along their entire length, 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 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.

[0039] The upper ends of the base wall portions 23a and 23b that form the mounting portion 26 of the divided body 1 have locking holes 23a2 and 23b2 that penetrate in the inward and outward directions, while the lower ends of the outer surfaces of the base wall portions 23a and 23b of the divided body 1 that is mounted on top have locking pieces 23a3 and 23b3. When the support members G of the support column, which are made up of divided bodies 1, 1 are stacked vertically, the locking pieces 23a3 and 23b3 of the divided body 1 that constitute the support member G of the upper support column lock into the locking holes 23a2 and 23b2 of the divided body 1 that constitute the support member G of the lower support column, so that the support members G, G of the support column are stacked and integrated vertically.

[0040] At the connection portion of the base wall portions 23a and 23b of the divided body 1 (the inner part of the corner portion of the divided wall portion 2), that is, at the connection portion of the second circumferential wall portions 242a2 and 242b2 of the filling recesses 24a and 24b in the base wall portions 23a and 23b, a recess 4 for arranging the temporary fixing member 3 is formed by recessing downward along its entire length in the inward and outward direction, so that it is fully open upward and inward.

[0041] As shown in Figure 6, the temporary fixing member 3 has a shaft 31 of a certain length and a column contact portion 32 formed at the tip of the shaft 31. Rotary shafts 311, 311 are provided protruding from both sides of the base end of the shaft 31 of the temporary fixing member 3, and support holes are formed on both side walls of the mounting recess 4 that can rotatably support the rotational shafts 311, 311 of the shaft 31 of the temporary fixing member 3, so that the temporary fixing member 3 is supported so that it can rotatably move up and down around its base end. Even when the support member body A of a support member G of another support column is placed on the mounting portion 26 of the divided body 1 that constitutes the support member body A of the support member G of a support column, the rotational shafts 311, 311 of the shaft 31 of the temporary fixing member 3 are supported on both side walls of the mounting recess 4 so that the temporary fixing member 3 can rotatably move up and down around its base end.

[0042] A filler receiving portion 312 is recessed on the upper surface of the shaft 31 of the temporary fixing member 3, extending along its entire length. As will be described later, after the support column P is placed in the support column holding portion A1 of the support member body A, the support column P is supported by the temporary fixing member 3. In this state, the temporary fixing member 3 is tilted over the upper end opening of the support column holding portion A1 of the support member body A, with its support column contact portion 32 in contact with the support column P. When filler material D is supplied into the support column holding portion A1 of the support member body A, a portion of the filler material D is supplied into the filler receiving portion 312 of the shaft 31 of the temporary fixing member 3, and the weight of the filler material D causes the temporary fixing member 3 to rotate in a direction that displaces the support column contact portion 32 downward around its base end, thereby more securely supporting the support column P by the temporary fixing member 3.

[0043] A column contact portion 32 is integrally formed at the tip of the shaft 31 of the temporary fixing member 3. The column contact portion 32 has a pair of support portions 321, 321 of a fixed length, integrally formed at the tip of the shaft 31. The pair of support portions 321, 321 are formed to be spaced apart from each other as they approach their tips. Elastic pieces 322, 322 are integrally formed at the tips of each of the pair of support portions 321, 321. The pair of elastic pieces 322, 322 are formed to protrude toward the column P in a planar convex arc shape, with their base ends integrally connected to the tips of the support portions 321, 321 and their tips formed as free ends. The tips of the pair of elastic pieces 322, 322 are arranged to be spaced apart from each other at a predetermined distance. Each pair of resilient pieces 322, 322 is configured to elastically deform in a way that allows it to return to its original shape around its base end, with its tip approaching the shaft 31, due to the pressure from the support column P, and to firmly support the support column P with its resilient force.

[0044] With the shaft 31 of the temporary fixing member 3 housed in the mounting recess 4, the column contact portion 32 is positioned within the column holding portion A1 of the support member body A, which is formed by combining the divided parts 1, 1. On the other hand, by rotating the temporary fixing member 3 in an upright direction around its base end, the distance between the column contact portions 32, 32 of the opposing temporary fixing members 3, 3 can be increased, and the distance between the column contact portions 32, 32 of the temporary fixing members 3, 3 can be adjusted to match the size of the column P held within the column holding portion A1 of the support member body A.

[0045] Furthermore, the column contact portion 32 of the temporary fixing member 3 only needs to be able to stably and temporarily fix the column, and is not limited to the structure described above.

[0046] 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. Each of the divided body 1 and the temporary fixing member 3 may contain reinforcing materials, fillers, etc.

[0047] Next, the procedure for manufacturing the support member G for the support column using the divided body 1 will be explained. By combining two divided bodies 1, 1, a support member G for one support column can be constructed, which has a support member body A having a support column holding part A1, and a temporary fixing member 3 disposed on the upper part (upper end) of the support member body A and for temporarily fixing the support column.

[0048] Specifically, two divided parts 1, 1 are prepared. As shown in Figure 4, the two divided parts 1, 1 are arranged so that their filling recesses 24a, 24b face outwards, and the first connecting parts 21, 21 and second connecting parts 22, 22 of one divided part 1 face the second connecting parts 22, 22 and first connecting parts 21, 21 of the other divided part 1.

[0049] 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 a support member G for the support column, which has a support member body A and a temporary fixing member 3 disposed on the upper part (upper end) of the support member body A (Figure 7). Multiple divided parts 1 can be brought to the construction site for the support member G for the support column, and since the divided parts 1 are lighter than the support member G for the support column, transportation from the storage location to the construction site can be easily carried out.

[0050] Furthermore, as shown in Figure 9, the divided body 1 can be placed upright by rotating the temporary fixing member 3 upwards around its base end, and then multiple divided bodies 1 can be stacked vertically with their filling recesses 24a and 24b facing upwards. Multiple divided bodies 1 can be stacked vertically by detachably fitting the protruding portions of the filling recesses 24a and 24b of the upper divided body 1 into the recesses of the filling recesses 24a and 24b of the lower divided body 1. The protruding portions 25 of the filling recesses 24a and 24b of the lower divided body 1 are detachably fitted into the protruding portions 25 of the 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 bodies 1 can be stacked neatly to reduce the overall volume and save storage space.

[0051] In the support member body A formed by integrating two divided bodies 1, 1, a vertically penetrating support column holding portion A1 is formed between the opposing surfaces of the divided bodies 1, 1, that is, the space enclosed by the bottom portions 241a, 241b of the filling recesses 24a, 24b.

[0052] At the upper end of the support member G 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 G of the support column.

[0053] A pair of temporary fixing members 3, 3 are positioned such that their entire shaft 31 is horizontal and housed within the mounting recess 4, with the column contact portions 32 facing each other within the column holding portion A1 of the support member body A. The temporary fixing member 3 is configured such that by rotating it upwards around the base end of its shaft 31, the spacing between the column contact portions 32, 32 of the pair of temporary fixing members 3, 3 can be widened according to the size of the column P. The pair of temporary fixing members 3, 3 support and temporarily fix 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 support member body A, or with the column portion protruding upward from the column holding portion A1.

[0054] The above describes a case where two divided parts 1 are combined to create one support member G for a support column. However, it is also possible to prepare two support members G for a 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 G 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 G for the support column, thereby connecting and integrating the two support members G, G vertically.

[0055] 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 G of the support column [Figure 8(a)]. The burial hole B is deep enough to bury the support member G of the support column along its entire vertical length. Gravel C or similar material is laid in the burial hole B as needed [Figure 8(b)].

[0056] Next, the support member G 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 G 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 body A is opened.

[0057] 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 G 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 column G 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.

[0058] 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.

[0059] A filler material D is supplied into the main body A of the support member G of the support column. Since the support member A1 of the support member G 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.

[0060] When the temporary fixing member 3 supports the support column P, the filler receiving portion 312 of the shaft 31 is located inside the support member body A, and a portion of the filler D supplied into the support member body A is supplied into the filler receiving portion 312 of the shaft 31 of the temporary fixing member 3. The temporary fixing member 3 receives a force that causes it to rotate downward around its base end due to the weight of the filler supplied to the filler receiving portion 312, so that the holding of the support column P by the temporary fixing members 3, 3 is not unexpectedly released. The support column P can be supported more firmly by the downward displacement of the support column contact portion 32 of the temporary fixing members 3, 3.

[0061] 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 support member G of the support column. Through these multiple filler material flow ports 251, the filler material D supplied into the column holding portion A1 flows out to the outside of the support member body A, that is, into the space formed between the opposing surfaces of the support member body A and the embedded hole B, and this space is filled with the filler material D [Figure 8(e)].

[0062] The filling recesses 24a and 24b of the divided body 1 are formed with inward recesses, while the protrusions 25 formed in the filling recesses 24a and 24b of the divided body 1 are formed with outward projections. The filling material D flows out from the support column holding part A1 to the outside of the support member body A through the filling material flow port 251 of the protrusion 25. Therefore, the filling material D flows into the filling recesses 24a and 24b of the divided body 1, while enveloping the protrusion 25.

[0063] Since the 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 filling recesses 27 at the corners of the divided wall portion 2, the divided body 1 constituting the main body A of the support member is embedded in the filling material D, surrounded by the filling material D filled in the filling recesses 24a and 24b.

[0064] Furthermore, in the divided wall portion 2 of the divided body 1 that constitutes the support member body A, a protruding portion 25 is formed that protrudes outward within the inwardly recessed filling recesses 24a and 24b. The wall portion A2 of the support member body A is formed by the divided wall portions 2 and 2 of the divided bodies 1 and 1. The divided wall portion 2 has large irregularities formed by the filling recesses 24a and 24b and the protruding portion 25, and the protruding portion 25 is surrounded by the filling material. The support member body A is then installed and fixed in the buried hole B with the filling material D firmly holding it in place by the anchoring effect.

[0065] Furthermore, the inside and outside of the column holding portion A1 of the support member body A are separated by filling recesses 24a and 24b. Although pressure is applied inward and outward from the filling material D to the bottom portion and the first to fourth peripheral wall portions 24a1 to 24a4 and 24b1 to 24b4 that constitute the filling recesses 24a and 24b, these pressures are largely canceled out. Therefore, the divided body 1 does not receive significant pressure from the filling material D, and the divided body 1 is positioned and fixed in the embedded hole B without causing much distortion, and can maintain a stable support for the column P over a long period of time.

[0066] Filler material D is filled into the column holding portion A1 of the support member body A and into the space formed between the opposing surfaces of the support member body A and the buried hole B. The support member body A is stably and 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 stably fixed in an upright position with the remaining portion, excluding its base end, protruding from the ground.

[0067] The above describes a case where the support member body A is constructed by combining multiple divided parts 1, 1, but the structure of the divided parts is not limited to the above structure. The support member body formed by combining multiple divided parts only needs to have a column holding part that can hold the base end of the column and allow a temporary fixing member that can support the column to be provided at the upper end. Furthermore, the support member body A of the column support member G does not have to be constructed by combining divided parts, but may be integrally molded using a mold or the like.
