[0009] [First embodiment] The pillar fixing structure of the first embodiment will be described below with reference to FIGS. 1 to 5. FIG. FIG. 1 is a front view showing a post unit 1 using the pillar fixing structure of the first embodiment, and FIG. 2 is a side view of the post unit 1. As shown in FIG. The post unit 1 comprises a post 10, a post box 3, a post cap 4, and an intercom 5. The post 10 is made of an extruded aluminum alloy material or the like, and in this embodiment is formed into a rectangular cylindrical shape with a pair of first side faces 11 on the long side and a pair of second side faces 12 on the short side. The post box 3 is a mailbox and is fixed to the pillar 10 in the vertical center with bolts or the like. The pillar cap 4 is a cap that covers the top end of the pillar 10. The pillar cap 4 may have built-in LED lighting. The intercom 5 is fixed to the top of the post box 3 on the front side of the pillar 10 with screws or the like. Inside the pillar 10, wiring for the LED lighting and wiring for the intercom 5 provided on the pillar cap 4 are arranged using CD pipes 6 or the like. In addition, a space is provided between the pillar cap 4 and the interphone 5 on the front side of the pillar 10 so that a nameplate 7 can be attached. In the following description, as shown in Figures 1 and 2, the horizontal direction along the first side surface 11 of the pillar 10 is referred to as the X-axis direction, the direction along the second side surface 12 is referred to as the Y-axis direction, and the up-down direction is referred to as the Z-axis direction. In the X-axis direction, the direction toward the left side in Figure 1 is referred to as the X1 direction, and the direction toward the right side in Figure 2 is referred to as the X2 direction. In the Y-axis direction, the direction toward the left side in Figure 2 is referred to as the Y1 direction, and the direction toward the right side in Figure 2 is referred to as the Y2 direction. In the Z-axis direction, the upward direction is referred to as the Z1 direction, and the downward direction is referred to as the Z2 direction.

[0010] The column 10 is fixed to the ground 50 via a formed base 2 . A foundation hole 51 is dug in the ground 50, and broken granite stones 52 serving as a foundation are laid at the bottom of the foundation hole 51. Instead of the broken granite stones 52, gravel or crushed stone may be laid. A formed foundation 2, which will be described later, is adhered to the lower end of the pillar 10. Then, the formed foundation 2 adhered to the lower end of the pillar 10 is placed in a foundation hole 51, and the foundation hole 51 is filled with soil 55, thereby fixing the pillar 10 to the ground 50 via the formed foundation 2.

[0011] Next, the forming base 2 will be described in detail with reference to FIGS. The formed foundation 2 is composed of a first divided foundation 20 and a second divided foundation 30 . The first split foundation 20 and the second split foundation 30 are each made of a synthetic resin molded body, specifically a foamed resin molded body such as polystyrene foam. Therefore, the first split foundation 20 and the second split foundation 30 can be molded individually using a mold, but they can also be easily molded by dividing a cubic foamed resin molded body into two using a cutter or the like and then processing grooves or the like.

[0012] The first divided foundation 20 has an upper surface 21, a bottom surface 22, a pair of side surfaces 23, an inclined surface 24, a first foundation facing surface 25, a second foundation facing surface 26, a first column facing surface 27, and a pair of second column facing surfaces 28. The upper surface 21 is a horizontal plane along the X-axis and Y-axis, and the length dimension in the X-axis direction along the first side surface 11 of the pillar 10 is set to be longer than the length in the Y-axis direction along the second side surface 12. The bottom surface 22 is positioned lower than the top surface 21 and is a horizontal plane along the X-axis and Y-axis. The length in the X-axis direction is the same as that of the top surface 21, but the length in the Y-axis direction is set longer than that of the top surface 21. The pair of side surfaces 23 are vertical surfaces that connect the edges of the top surface 21 and the bottom surface 22 along the Y-axis direction, and are formed in a trapezoidal shape. The inclined surface 24 is an inclined surface that extends along the X-axis direction of the top surface 21 and the bottom surface 22, connecting the edges that are farther away from the column 10, and that extends downward away from the column 10 and outward, i.e., in the Y1 direction.

[0013] The first foundation facing surface 25 and the second foundation facing surface 26 are vertical surfaces along the X-axis direction. The first foundation facing surface 25 is provided continuously with the top surface 21, the bottom surface 22, and the side surface 23 of the two side surfaces 23 that is closer to the X1 direction. The second foundation facing surface 26 is provided continuously with the top surface 21, the bottom surface 22, and the side surface 23 of the two side surfaces 23 that is closer to the X2 direction. These first foundation facing surface 25 and second foundation facing surface 26 are parallel to the first side surface 11 of the column 10, are provided spaced apart in the X-axis direction, and are provided opposite the second foundation facing surface 36 and first foundation facing surface 35 of the second divided foundation 30 described below. The first pillar facing surface 27 is a vertical surface provided opposite to the first side surface 11 of the pillar 10. The first pillar facing surface 27 is provided between the first foundation facing surface 25 and the second foundation facing surface 26 in the X-axis direction. The width dimension of the first pillar facing surface 27, i.e., the dimension in the X-axis direction, is approximately the same as the width dimension of the first side surface 11 of the pillar 10. The pair of second pillar facing surfaces 28 are vertical surfaces respectively provided opposite a pair of second side surfaces 12 of the pillar 10, and are surfaces that connect the first foundation facing surface 25 and the second foundation facing surface 26 to the first pillar facing surface 27. For this reason, the first pillar facing surface 27 is provided continuous with the two second pillar facing surfaces 28. In addition, the width dimension of the second pillar facing surface 28, i.e., the dimension in the Y-axis direction, is set to approximately half the width dimension of the second side surfaces 12 of the pillar 10. In the first divided foundation 20, the first column facing surface 27 and the pair of second column facing surfaces 28 form a recessed groove in which the column 10 is placed.

[0014] Similar to the first split foundation 20, the second split foundation 30 has an upper surface 31, a bottom surface 32, a pair of side surfaces 33, an inclined surface 34, a first foundation facing surface 35, a second foundation facing surface 36, a first column facing surface 37, and a pair of second column facing surfaces 38. The upper surface 31 is a horizontal plane along the X-axis and Y-axis, and the length dimension in the X-axis direction along the first side surface 11 of the pillar 10 is set to be longer than the length in the Y-axis direction along the second side surface 12. The bottom surface 32 is positioned lower than the top surface 31 and is a horizontal plane along the X-axis and Y-axis. The length in the X-axis direction is the same as that of the top surface 31, but the length in the Y-axis direction is set longer than that of the top surface 31. The pair of side surfaces 33 are vertical surfaces that connect the edges of the top surface 31 and the bottom surface 32 along the Y-axis direction, and are formed in a trapezoidal shape. The inclined surface 34 is an inclined surface that extends along the X-axis direction of the top surface 31 and the bottom surface 32, connecting the edges that are away from the column 10, and that extends downward away from the column 10 and outward, i.e., in the Y2 direction.

[0015] The first foundation facing surface 35 and the second foundation facing surface 36 are vertical surfaces along the X-axis direction. The first foundation facing surface 35 is provided continuously with the top surface 31, the bottom surface 32, and the side surface 33 of the two side surfaces 33 that is closer to the X1 direction. The second foundation facing surface 36 is provided continuously with the top surface 31, the bottom surface 32, and the side surface 33 of the two side surfaces 33 that is closer to the X2 direction. These first foundation facing surface 35 and second foundation facing surface 36 are parallel to the first side surface 11 of the column 10, are provided at a distance from each other in the X-axis direction, and are provided opposite the second foundation facing surface 26 and the first foundation facing surface 25 of the first divided foundation 20. The first pillar facing surface 37 is a vertical surface provided opposite to the first side surface 11 of the pillar 10. The first pillar facing surface 37 is provided between the first foundation facing surface 35 and the second foundation facing surface 36 in the X-axis direction. The width dimension of the first pillar facing surface 37, i.e., the dimension in the X-axis direction, is approximately the same as the width dimension of the first side surface 11 of the pillar 10. The pair of second pillar facing surfaces 38 are vertical surfaces respectively provided opposite the pair of second side surfaces 12 of the pillar 10, and are surfaces that connect the first foundation facing surface 35 and the second foundation facing surface 36 to the first pillar facing surface 37. For this reason, the first pillar facing surface 37 is provided continuous with the two second pillar facing surfaces 38. In addition, the width dimension of the second pillar facing surface 38, i.e., the dimension in the Y-axis direction, is set to approximately half the width dimension of the second side surfaces 12 of the pillar 10. In the second divided foundation 30, a groove in which the pillar 10 is placed is formed by the first pillar facing surface 37 and the pair of second pillar facing surfaces 38. Therefore, a pillar placement hole in which the pillar 10 is placed is defined by the groove of the first divided foundation 20 and the groove of the second divided foundation 30, that is, by the first pillar facing surfaces 27, 37 and the second pillar facing surfaces 28, 38.

[0016] A recessed groove 39 is formed on the bottom surface 32 of the second divided foundation 30, continuing from the first column-facing surface 37 to the inclined surface 34. The recessed groove 39 is a groove in which a CD pipe 6 for wiring or the like is placed. In addition, an opening 13 is formed on the lower end of the first side surface 11 of the column 10 for drawing the CD pipe 6 from the inside to the outside of the column 10, and the recessed groove 39 is formed in a position opposite the opening 13.

[0017] The first foundation facing surface 25 and the second foundation facing surface 26 of the first divided foundation 20 configured as described above and the second foundation facing surface 36 and the first foundation facing surface 35 of the second divided foundation 30 are adhered together using double-sided tape 41 and 42, which are foundation adhering means. As shown in FIGS. 3 and 4, the double-sided tape 41 and the double-sided tape 42 are attached along the upper and lower ends of the first foundation facing surface 25 and the second foundation facing surface 26 of the first divided foundation 20. The first divided foundation 20 and the second divided foundation 30 are bonded to the pillar 10 by double-sided tapes 43, 44, 45, and 46, which are pillar bonding means. 3 and 4, double-sided tape 43 and double-sided tape 44 are attached along the upper and lower edges of first column-facing surface 27 of first divided foundation 20. Double-sided tape 45 and double-sided tape 46 are attached along the upper and lower edges of first column-facing surface 37 of second divided foundation 30. Note that, because groove 39 is opened on the lower end side of first column-facing surface 37, double-sided tape 46 is attached to the portion of first column-facing surface 37 other than the opening of groove 39.

[0018] Then, the release paper of each double-sided tape 41-46 is peeled off, and the first divided foundation 20 and the second divided foundation 30, which are arranged on either side of the pillar 10, are joined together as shown in Figure 3. That is, the second foundation facing surface 36 is adhered to the first foundation facing surface 25, and the first foundation facing surface 35 is adhered to the second foundation facing surface 26. In this way, the first divided foundation 20 and the second divided foundation 30 are adhered to form the formed foundation 2. In addition, the double-sided tapes 43-46 are each adhered to a pair of first side surfaces 11 of the pillar 10. In this case, since double-sided tape is not placed on the second column facing surfaces 28, 38, the first divided foundation 20 and the second divided foundation 30 can reliably adhere each double-sided tape 43 to 46 to the first side surface 11 of the column 10 by moving the second column facing surfaces 28, 38 along the second side surface 12 of the column 10, and further, the double-sided tapes 41, 42 can reliably adhere the first foundation facing surfaces 25, 35 and the second foundation facing surfaces 26, 36.

[0019] Next, a method for constructing the pillar 10 will be described with reference to FIG. The first and second divided foundations 20 and 30 that make up the formed foundation 2 are preformed in a factory or the like. For example, if the first and second divided foundations 20 and 30 are made of polystyrene foam, they can be formed by cutting a rectangular polystyrene foam block with a polystyrene cutter. That is, by turning the second divided foundation 30 upside down and bringing the inclined surface 24 of the first divided foundation 20 and the inclined surface 34 of the second divided foundation 30 into close contact with each other, the rectangular divided foundation 20 and the second divided foundation 30 become roughly rectangular. Therefore, the rectangular polystyrene foam block is diagonally cut at the portions that will become the inclined surfaces 24 and 34, grooves are machined into the vertical surfaces to form the first column-facing surfaces 27 and 37 and the second column-facing surfaces 28 and 38, and then groove 39 is machined to form the first and second divided foundations 20 and 30. Next, the components that make up the post unit 1, such as the molded first divided foundation 20, second divided foundation 30, pillar 10, post box 3, pillar cap 4, intercom 5, etc., are transported to the construction site of the post unit 1. The double-sided tapes 43 to 46 may be attached to the first divided foundation 20 and second divided foundation 30 in the factory, or may be attached at the construction site of the post unit 1.

[0020] At the construction site of the post unit 1, as shown in FIG. 5(A), the ground 50 is dug to form a foundation hole 51, and broken gravel stones 52 or the like are laid at the bottom of the foundation hole 51. Next, the pillar 10, the first divided foundation 20 and the second divided foundation 30 are attached using double-sided tapes 43 to 46, which are foundation adhesive means and pillar adhesive means. Next, as shown in FIG. 5(B), the first divided foundation 20 and the second divided foundation 30 adhered to the pillar 10, that is, the formed foundation 2, are placed on the broken rubble stones 52 in the foundation hole 51. Thereafter, the soil used when the foundation hole 51 was dug can be backfilled into the foundation hole 51, thereby fixing the formed foundation 2 in the foundation hole 51 as shown in Figures 1 and 2. The weight of the soil 55 backfilled in the foundation hole 51 applies a vertical load to the inclined surfaces 24, 34, and the formed foundation 2 in the foundation hole 51 can be fixed by the soil 55. Therefore, the inclined surfaces 24, 34 function as load-bearing surfaces that support the load from the soil 55. Thereafter, the post box 3, the post cap 4, the intercom 5, the nameplate 7, etc. are attached to the post 10. This completes the installation of the post unit 1.

[0021] [Effects of the first embodiment] According to the first embodiment, the first foundation facing surface 25 and the second foundation facing surface 26 of the first split foundation 20 are adhered to the second foundation facing surface 36 and the first foundation facing surface 35 of the second split foundation 30 using double-sided tape 41 and 42, which are foundation adhering means, and the column 10 is adhered to the first column facing surfaces 27 and 37 using double-sided tape 43 to 46, which are column adhering means.Therefore, there is no need to form through holes in each split foundation for the connecting shaft to pass through or to provide an iron plate for the nut to abut, which improves construction workability and reduces costs.

[0022] In the first embodiment, the first side surface 11 of the column 10, which has the larger width dimension, is adhered to the first column facing surfaces 27, 37 of the first divided foundation 20 and the second divided foundation 30 using double-sided tape 43 to 46, so the column 10 can be adhered and fixed to the molded foundation 2 without having to adhere the second side surface 12, which has the smaller width dimension, to the second column facing surfaces 28, 38. Since the second side surface 12 of the column 10 is not bonded to the second column opposing surfaces 28, 38, the first divided foundation 20 and the second divided foundation 30 can be bonded to each other while guiding the second column opposing surfaces 28, 38 with the second side surface 12, so that the bonding work between the divided foundations and between the column and the divided foundation can be easily performed.

[0023] The double-sided tapes 41 to 46 are provided at the upper and lower ends of the first and second divided foundations 20 and 30 where the moment applied from the pillar 10 to each divided foundation 20, 30 is greatest, thereby improving the fixing strength of the pillar 10. Furthermore, the first divided foundation 20 and the second divided foundation 30 are provided with inclined surfaces 24, 34 that serve as load-supporting surfaces, so that vertical loads can be applied to the inclined surfaces 24, 34 with the soil 55 filled in the foundation hole 51, and the formed foundation 2 in the foundation hole 51 can be firmly fixed with the soil 55, which also improves the fixing strength of the column 10.

[0024] The first and second divided foundations 20 and 30 are formed from molded bodies such as polystyrene foam, and the adhesive is double-sided tape 41-46. Therefore, compared to wet construction in which mortar or concrete is poured at the construction site to fix the pillars, construction can be carried out using dry construction, which does not require mixing or curing concrete, thereby shortening the construction period and improving construction workability. Furthermore, the weight of each divided foundation 20, 30 can be reduced, making it easy to handle the divided foundations 20, 30 and improving workability when installing them in the foundation hole 51.

[0025] [Second embodiment] Next, a second embodiment will be described with reference to Fig. 6. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted. In the second embodiment, a formed foundation 2B is composed of a first divided foundation 20B and a second divided foundation 30B. The first divided foundation 20B has a stepped inclined surface 24B, and the second divided foundation 30B has a stepped inclined surface 34B, which is different from the first embodiment, but the other configurations are the same.

[0026] The formed foundation 2B of the second embodiment can achieve the same effects as the first embodiment. Furthermore, because each of the inclined surfaces 24B, 34B is stepped, when the foundation hole 51 is filled with soil 55, the vertical load due to the weight of the soil 55 is effectively applied to the horizontal surfaces of the inclined surfaces 24B, 34B, and the formed foundation 2B can be more reliably fixed by the soil 55 filled in the foundation hole 51.

[0027] [Third embodiment] Next, a third embodiment will be described with reference to Fig. 7. In the third embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted. The formed foundation 2C of the third embodiment is made up of a first divided foundation 20C and a second divided foundation 30C. Note that Fig. 7 is a top view showing the state in which the first divided foundation 20C and the second divided foundation 30C are attached to the column 10. The first split foundation 20C has a first foundation facing surface 25C and a first column facing surface 27C that are continuous on the same plane, and only the second foundation facing surface 26C, which is continuous with the first column facing surface 27C via the second column facing surface 28C, protrudes from the first column facing surface 27C. Like the first split foundation 20C, the second split foundation 30C has a first foundation facing surface 35C and a first column facing surface 37C that are continuous on the same plane, and only the second foundation facing surface 36C, which is continuous with the first column facing surface 37C via the second column facing surface 38C, protrudes from the first column facing surface 37C. The other configurations of the first divided foundation 20C and the second divided foundation 30C are the same as those in the first embodiment, and therefore description thereof will be omitted.

[0028] In the third embodiment, double-sided tape 41C is continuously affixed to both the upper and lower ends of the second foundation facing surface 26C, the second pillar facing surface 28C, and the first pillar facing surface 27C of the first divided foundation 20C. Also, double-sided tape 45C is continuously affixed to both the upper and lower ends of the second foundation facing surface 36C, the second pillar facing surface 38C, and the first pillar facing surface 37C of the second divided foundation 30C.

[0029] In the third embodiment, the double-sided tape 41C attached to the second foundation facing surface 26C of the first divided foundation 20C is adhered to the first foundation facing surface 35C of the second divided foundation 30C, the double-sided tape 41C attached to the second column facing surface 28C is adhered to the second side surface 12 of the column 10, and the double-sided tape 41C attached to the first column facing surface 27C is adhered to the first side surface 11 of the column 10. In addition, the double-sided tape 45C attached to the second foundation facing surface 36C of the second divided foundation 30C is adhered to the first foundation facing surface 25C of the first divided foundation 20C, the double-sided tape 45C attached to the second column facing surface 38C is adhered to the second side surface 12 of the column 10, and the double-sided tape 45C attached to the first column facing surface 37C is adhered to the first side surface 11 of the column 10.

[0030] The formed foundation 2B of the third embodiment can achieve the same effects as those of the first embodiment. Furthermore, since the first foundation facing surfaces 25C and 35C are made flush with the first column facing surfaces 27C and 37C, the first divided foundation 20C and the second divided foundation 30C can be easily machined with a cutter or the like, improving workability during the processing and manufacturing of the first divided foundation 20C and the second divided foundation 30C. Furthermore, the double-sided tapes 41C, 45C can be applied continuously from the second foundation facing surfaces 26C, 36C to the first pillar facing surfaces 27C, 37C, which also improves workability. Furthermore, since both the first side surface 11 and the second side surface 12 of the pillar 10 can be adhered to the first divided foundation 20C and the second divided foundation 30C, the fixing strength of the pillar 10 can be further improved.

[0031] [Fourth embodiment] Next, a fourth embodiment will be described with reference to Fig. 8. In the fourth embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted. The formed foundation 2D of the fourth embodiment is composed of the same first divided foundation 20 and second divided foundation 30 as in the first embodiment. However, it differs from the first embodiment in that a sheet-like watertight material 60 such as a sponge is placed between the second side surface 12 of the pillar 10 and the second pillar opposing surfaces 28, 38.

[0032] The forming base 2D of the fourth embodiment can achieve the same effects as the first embodiment. In addition, the provision of the watertight material 60 can prevent water from entering between the second side surface 12, which is not adhered with double-sided tape, and the second column-facing surfaces 28, 38.

[0033] [Variations] The present invention is not limited to a fixing structure for the pillar 10 of the post unit 1, but can be used as a fixing structure for various pillars and supports installed outdoors. The column 10 is not limited to a rectangular tubular shape, but may be a cylindrical column, or may be a solid column instead of a hollow tubular column. The shapes of the column placement holes in the first and second divided foundations of the formed foundation may be set to match the cross-sectional shape of the column. For example, if the column is cylindrical, the first and second divided foundations may each be formed with a semicircular column-facing surface, and the two divided foundations may be joined to form a circular column placement hole.

[0034] The base adhesive means and the post adhesive means are not limited to double-sided tape, but may be adhesive. The divided base constituting the formed base is not limited to being divided into two parts, but may be divided into three or more parts. The divided foundation is not limited to being made of polystyrene foam, but may be made of foamed resin molded bodies such as polyethylene, polypropylene, polyurethane, etc. Furthermore, the divided foundation may be made of unfoamed synthetic resin molded bodies, or molded bodies made of mortar or concrete.

[0035] [Summary of the invention] The present invention is a pillar fixing structure for fixing a pillar in a foundation hole formed in the ground, comprising a pillar and a shaped foundation that is adhered to the lower end of the pillar by an adhesive means, installed in the foundation hole, and filled with soil, wherein the shaped foundation is composed of a plurality of divided foundations arranged on either side of the pillar, and each divided foundation has a foundation facing surface that faces the other divided foundations, and a pillar facing surface that defines a pillar placement hole in which the pillar is placed and faces the side of the pillar, and the adhesive means comprises foundation adhesive means that adheres the foundation facing surfaces of each divided foundation to each other, and pillar adhesive means that adheres the pillar to the pillar facing surface. According to the present invention, the foundation facing surface of one divided foundation is bonded to the foundation facing surface of another divided foundation using a foundation bonding means, and the columns are bonded to the column facing surfaces using a column bonding means.This eliminates the need to form a through hole in the divided foundation for the connecting shaft to pass through, or to provide an iron plate for the nut to abut, thereby improving construction workability and reducing costs.

[0036] In the pillar fixing structure of the present invention, it is preferable that the pillar is formed in a planar rectangular shape and has a pair of first side surfaces and a pair of second side surfaces whose width dimension is shorter than that of the first side surfaces, the pillar facing surfaces have a first pillar facing surface facing the first side surfaces and a second pillar facing surface facing the second side surfaces, and the pillar bonding means bonds the first side surfaces to the first pillar facing surfaces. According to the present invention, in a planar rectangular column, a pair of first side surfaces with a long width dimension are adhered to the first column-facing surfaces of the divided foundation by column adhesive means, so the column can be adhered and fixed to the formed foundation without adhering the second side surfaces to the second column-facing surfaces. Also, because there is no need to adhere the second side surfaces to the second column-facing surfaces, the divided foundations can be adhered to each other while guiding the second column-facing surfaces with the second side surfaces of the columns, making it easy to adhere the divided foundations to each other and the columns to the divided foundations.

[0037] In the pillar fixing structure of the present invention, a sheet-like watertight material may be arranged between the second side surface of the pillar and the second pillar opposing surface. According to the present invention, a watertight material is arranged between the second side surface of the pillar and the second pillar facing surface, so that the watertight material can prevent water from entering even without bonding the second side surface and the second pillar facing surface.

[0038] In the column fixing structure of the present invention, it is preferable that the formed foundation is composed of two split foundations, the foundation facing surfaces are composed of a first foundation facing surface and a second foundation facing surface that are parallel to the first side surface and horizontally spaced apart, the column facing surfaces are composed of the first column facing surface and two second column facing surfaces that are perpendicular to the first column facing surface, the foundation bonding means bonds the upper and lower ends of the first foundation facing surface and the second foundation facing surface of one split foundation to the upper and lower ends of the second foundation facing surface and the first foundation facing surface of the other split foundation, and the column bonding means bonds the upper and lower ends of the first column facing surface of one split foundation to the first side surface of one of the columns, and bonds the upper and lower ends of the first column facing surface of the other split foundation to the first side surface of the other of the columns. According to the present invention, the two divided foundations can be constructed to have the same shape, thereby improving the productivity of each divided foundation. Furthermore, the foundation adhesive means adheres the upper and lower ends of the first and second foundation facing surfaces to each other, and the column adhesive means adheres the upper and lower ends of the first column facing surface of each divided foundation to each first side surface of the column, so that effective adhesion can be achieved in the areas where the moment applied from the column is greatest, ensuring fixing strength while reducing the amount of adhesive used.

[0039] In the column fixing structure of the present invention, the formed foundation is composed of two divided foundations, the foundation facing surface is composed of a first foundation facing surface and a second foundation facing surface, the column facing surface is composed of the first column facing surface and the second column facing surface, the first foundation facing surface is provided parallel to the first side surface, the first column facing surface is provided continuously on the same plane as the first foundation facing surface, the second column facing surface is provided continuously in a direction perpendicular to the first column facing surface, the second foundation facing surface is provided continuously in a direction perpendicular to the second column facing surface, and the foundation adhesive means may bond the upper and lower ends of the first foundation facing surface and the second foundation facing surface of one divided foundation to the upper and lower ends of the second foundation facing surface and the first foundation facing surface of the other divided foundation, and the column bonding means may bond the upper and lower ends of the first column facing surface and the second column facing surface of one divided foundation to the first side surface and the second side surface of one of the columns, and bond the upper and lower ends of the first column facing surface and the second column facing surface of the other divided foundation to the first side surface and the second side surface of the other of the columns. According to the present invention, each divided foundation can be formed to the same shape, thereby improving productivity of each divided foundation. Furthermore, since the foundation adhesive means adheres the upper and lower ends of the first foundation facing surface and the second foundation facing surface to each other, and the column adhesive means adheres the upper and lower ends of the first column facing surface of each divided foundation to each first side surface of the column, fixing strength can be ensured while reducing the amount of each adhesive means used.

[0040] In the pole fixing structure of the present invention, the base adhesive means and the pole adhesive means are preferably double-sided tapes. According to the present invention, double-sided tape is used as each adhesive means, which improves workability during adhesion and shortens the installation time. Furthermore, the adhesive areas where the double-sided tape is placed can also prevent rainwater from entering.

[0041] In the column fixing structure of the present invention, it is preferable that each of the divided foundations has a load bearing surface that receives a load applied vertically by the soil. According to the present invention, a load is applied vertically downward to the load-bearing surface by the soil filled in the foundation hole, thereby improving the strength with which the formed foundation is fixed in the foundation hole.

[0042] In the column fixing structure of the present invention, it is preferable that the divided foundation is made of a foamed resin molded body. According to the present invention, the split foundation is made of foamed resin molding, which makes it lighter than split foundations made of mortar or concrete. This makes the split foundation easier to handle and improves the workability when installing it in the foundation hole. [Explanation of symbols]
