Description

[Technical Field]

[0001] The present invention relates to a pillar fixing structure. [Background technology]

[0002] BACKGROUND ART A known method of constructing a fence involves inserting fence posts to be installed on a block wall into holes in the blocks and then fixing the posts by pouring mortar into the holes (see Patent Document 1). However, the structure of fixing the pillars using mortar has problems in terms of workability and construction time. Therefore, in order to simplify and shorten the construction time, a method of fixing the pillars in the foundation holes using a hardening resin such as urethane resin is known (see Patent Document 2).

[0003] Patent Document 2 discloses a method for constructing a columnar structure comprising filling a foundation hole formed in the ground with a cured resin material and providing a cover member on the cured resin material with a through hole, and embedding and fixing one end of the columnar object in the cured resin material through the through hole of the cover member.

[0004] [Patent Document 1] Japanese Patent Application Publication No. 10-280739 [Patent Document 2] Japanese Patent Publication No. 2020-158995 Summary of the Invention [Problem to be solved by the invention]

[0005] However, when the lower end of the column is inserted into the block holes of the block wall or the foundation holes on the ground, and then a curable resin such as urethane resin is filled, and the upper surface thereof is covered with a cover member, there is a problem that rainwater that has penetrated through the gap between the through-hole of the cover member and the column inserted into the through-hole remains between the cover member and the curable resin. In this case, when the remaining rainwater freezes and expands in volume, the cover member may be deformed or lifted. There is also a problem that curable resins such as urethane resin with low weather resistance are exposed to the outside and are easily deteriorated by wind, rain, and ultraviolet rays.

[0006] An object of the present invention is to provide a column fixing structure that can exhibit high weather resistance, improve workability, and shorten the construction period.

Means for Solving the Problems

[0007] The column fixing structure of the present invention includes a column, a base portion having a fixing hole into which the lower end portion of the column is inserted, a resin cured product that is filled in the fixing hole to fix the column, and a cover member that is installed on the upper surface of the base portion and covers the upper surface of the resin cured product. The cover member is characterized by including a drainage portion capable of draining water that has penetrated between the resin cured product and the cover member.

Effects of the Invention

[0008] According to the present invention, it is possible to provide a column fixing structure that can exhibit high weather resistance, improve workability, and shorten the construction period.

Mode for Carrying Out the Invention

[0010] [First Embodiment] Hereinafter, the fixing structure of the pillar of the first embodiment will be described with reference to FIGS. 1 to 6. FIG. 1 is a perspective view of a fence 1 using the fixing structure of the pillar of the first embodiment. The fence 1 includes a fence body 5 and a pillar 10 that supports the fence body 5. The pillar 10 is fixed to the block wall 2 by a pillar fixing structure described later. The block wall 2 is configured by arranging concrete blocks 3 stacked in two levels vertically side by side. As shown in Fig. 4, the concrete block 3 is formed with fixing holes 31 penetrating vertically. Further, a recess is formed on the upper surface of the concrete block 3. This recess is filled with a filler 32 formed by placing mortar or concrete on-site. The fixing hole 31 of the concrete block 3 is a fixing hole into which the lower end of the column 10 is inserted as described later, and filled with foamed urethane obtained by injecting urethane resin, foaming, and curing. The block wall 2 composed of the concrete blocks 3 is the base part. Note that the urethane resin starts to foam when mixed and cures after a predetermined time. The state having fluidity before curing is called urethane resin or curable resin, and the state after curing is called foamed urethane or resin cured product.

[0011] The fence body 5 is configured in a panel shape by combining an upper body edge, a lower body edge, vertical frames, horizontal grids, vertical grids, etc. Note that the type of the fence body 5 is not limited to the horizontal grid type shown in Fig. 1, and may be appropriately selected from a vertical grid type, a horizontal concealment type, a vertical concealment type, a lattice grid type, a latticed grid type, a polycarbonate panel type, etc. Each member of the fence body 5 is composed of an extruded profile made of an aluminum alloy or the like.

[0012] As shown also in Figs. 2 and 4, the column 10 is composed of an extruded profile made of an aluminum alloy formed in a square tube shape. The column 10 is formed with a through-hole 11 through which the level pin 15 is inserted. The level pin 15 is composed of a round bar, is inserted into the through-hole 11, and protrudes from both side surfaces of the column 10. This level pin 15 is detachably inserted into the through-hole 11 of the column 10. The lower end of the column 10 is open, and when the level pin 15 is placed on the upper surface of the concrete block 3, the lower end of the column 10 is set to be positioned above the bottom surface of the fixing hole 31. Note that the bottom surface of the fixing hole 31 of the upper concrete block 3 is constituted by, for example, the upper surface of the filling material 32 when the fixing hole 31 of the lower concrete block 3 is blocked with the filling material 32 or the like. Also, when the fixing holes 31 of the upper and lower two concrete blocks 3 are continuous, the bottom surface of the fixing hole 31 is constituted by the ground on which the lower concrete block 3 is installed.

[0013] As shown in FIG. 2, a lid member 20 that covers the upper surface of the fixing hole 31 of the block wall 2 is attached to the column 10. The lid member 20 is composed of two split lids 20A and 20B that are split into two. Each of the split lids 20A and 20B is a component of the same shape and the same size, and the dividing line is set along the long side direction of the concrete block 3. As also shown in FIG. 3, the split lids 20A and 20B have a fixing portion 21, a covering portion 22, and a side surface portion 23.

[0014] Each fixing portion 21 includes a long side portion 211 provided along the long side of the concrete block 3 and a pair of short side portions 212 extending orthogonally from both ends of the long side portion 211 and provided along the short side of the concrete block 3, and is formed in a substantially U shape in a plan view seen from above. A through-hole 213 and a drain hole 214 are formed in the long side portion 211. The through-hole 213 is a round hole through which the tapping screw 25 is inserted, and the drain hole 214 is a rectangular concave groove cut out from the lower surface of the long side portion 211, and the lower end is open. Each fixing part 21 is fixed to the column 10 by tapping screws 25 screwed to the side surface of the column 10 through the through holes 213. At this time, since the long side part 211 and the short side part 212 are provided along the side surface of the column 10, in the state where each divided lid 20A, 20B is fixed to the column 10, the fixing part 21 is arranged so as to surround the four side surfaces of the column 10.

[0015] Each covering part 22 extends outward from the fixing part 21. The height position of each covering part 22 is between the through hole 213 and the drain hole 214 of the long side part 211. The covering part 22 extends to a position outside the upper surface opening of the fixing hole 31 and is formed so as to cover the fixing hole 31 from above in the state where each divided lid 20A, 20B is fixed to the column 10. Each side surface part 23 extends downward from the outer periphery of the covering part 22 and includes a long side part 231 provided along the long side of the concrete block 3 and a pair of short side parts 232 provided along the short side of the concrete block 3. The lower end surfaces of the long side part 231 and the short side part 232 are configured to be able to contact the upper surfaces of the concrete block 3 and the filler 32. A drain hole 234 is formed in the long side part 231. The drain hole 234 is a rectangular concave groove cut out from the lower surface of the long side part 231, similar to the drain hole 214, and the lower end is open. The drain hole 214 and the drain hole 234 are formed at positions overlapping in the direction orthogonal to the surfaces of the long side part 211 and the long side part 231, that is, in the short side direction of the concrete block 3. These drain holes 214, 234 are also used as holes through which the level pin 15 is inserted, as will be described later.

[0016] Next, the process of constructing the fence 1 using the fixing structure of the column 10 will be described with reference to FIGS. 4 to 6. First, the block wall 2 is constructed with the concrete blocks 3. Next, as shown in FIG. 4, the level pin 15 is inserted into the column 10, and as shown in FIG. 5(A), the lower end portion of the column 10 is inserted into the fixing hole 31 of the block wall 2, and the level pin 15 is placed on the upper surface of the concrete block 3. At this time, as shown in FIG. 6, the lower end of the column 10 is open and is located above the bottom surface of the fixing hole 31. Next, urethane resin is injected between the fixing hole 31 and the column 10. The urethane resin injected into the fixing hole 31 is filled from the opening at the lower end of the column 10 to the inside of the column 10, and foams and cures. For this reason, the inside of the fixing hole 31 and the column 10 is filled with foamed urethane 40. Note that the amount of urethane resin injected into the fixing hole 31 is preset to the amount that fills up to the upper surface of the fixing hole 31 when the urethane resin foams and cures to become the foamed urethane 40.

[0017] Next, as shown in FIG. 5(B) and FIG. 6, the split lids 20A and 20B are fixed to the column 10. Specifically, the split lids 20A and 20B are placed on the upper surface of the concrete block 3 in such a direction that the level pins 15 are arranged in the drain holes 214 and 234, and are fixed to the side surface of the column 10 using the tapping screws 25. After the injected urethane resin has cured to a certain extent and the column 10 can be supported, the level pins 15 are removed. As a result, as shown in FIG. 2, the column 10 is fixed to the block wall 2 via the foamed urethane 40 which is a resin cured product. Next, the fence body 5 is fixed to the column 10 using brackets or the like. Thus, the construction of the fence 1 is completed.

[0018] [Effects of the First Embodiment] According to the first embodiment, since the column 10 inserted into the fixing hole 31 of the concrete block 3 is fixed with the foamed urethane 40 filled in the fixing hole 31, the curing time can be shortened and the construction period can be shortened compared with the case of fixing with mortar. In addition, since the urethane resin that becomes the foamed urethane 40 is lighter and easier to handle than mortar, the workability can be improved. Since the lid member 20 that covers the upper surface of the foamed urethane 40 is provided, it is possible to prevent the foamed urethane 40 from being exposed to the outside. Thereby, it is possible to prevent the foamed urethane 40 from being deteriorated by being exposed to ultraviolet rays or the like, the weather resistance can be improved, and the design property of the fixed portion of the column can also be improved. Since the drain holes 214 and 234 are formed in the lid member 20, rainwater that has entered between the lid member 20 and the urethane foam 40 through the gap between the column 10 and the lid member 20 can be drained from the drain holes 214 and 234. Therefore, it is possible to prevent rainwater from accumulating between the lid member 20 and the urethane foam 40, and prevent the lid member 20 from being deformed due to the freezing of the stagnant water, thereby preventing the deterioration of weather resistance and design.

[0019] Since the fixing portion 21 of the lid member 20 is brought into contact with the side surface of the column 10 and fixed with the tapping screw 25, the lid member 20 can be easily fixed to the column 10. Further, since the lower end of the side surface portion 23 extending downward from the outer periphery of the covering portion 22 is placed on the upper surface of the concrete block 3, a space can be secured between the upper surface of the concrete block 3 and the covering portion 22. Therefore, even if the urethane foam 40 slightly overflows from the fixing hole 31, it can be stored in the above space, and there is no need to cut off the urethane foam 40 that has overflowed from the fixing hole 31 with a cutter or the like, so the workability can also be improved. Furthermore, since the drain hole 234 is formed in the side surface portion 23, rainwater and the like that have entered the above space can be surely drained. Since the lid member 20 is composed of the split lids 20A and 20B, after injecting the urethane resin into the fixing hole 31, each split lid 20A and 20B can be easily attached to the column 10, and the workability of the construction work can be improved.

[0020] By placing the level pin 15 on the upper surface of the concrete block 3, the height position of the column 10 can be set. Therefore, the lower end portion of the column 10 disposed in the fixing hole 31 can be arranged with the height dimension necessary for fixing the column 10. Further, since the cover member 20 is formed with drain holes 214 and 234 through which the level pin 15 can be inserted and which also serve as drain portions, the cover member 20 can be installed with the level pin 15 attached to the column 10, and the cover member 20 can be installed immediately after injecting urethane resin into the fixing hole 31. Also, after the foamed urethane 40 has foamed and cured, the level pin 15 can be removed without removing the cover member 20, improving the workability of the construction. Furthermore, even if the foamed urethane 40 overflows from the fixing hole 31 and fills the space between the covering portion 22 and the upper surface of the concrete block 3, a continuous drain hole is formed from the inside of the column 10 to the outside of the cover member 20 by removing the level pin 15, so that the drainage performance can be maintained.

[0021] Since the foamed urethane 40 can also be filled inside the column 10, the foamed urethane 40 is filled both inside and outside the column 10, improving the fixing strength of the column 10. Since the cured resin is the foamed urethane 40 filled in the fixing hole 31 and inside the column 10 by foaming, the amount of resin used can be reduced and the workability can be improved.

[0022] [Second Embodiment] Next, the fixing structure of the column according to the second embodiment will be described with reference to FIGS. 7 to 9. The second embodiment is a fixing structure for fixing the column 10B to a fixing hole 51 formed in the ground 50 which is the base portion. As shown in FIGS. 8 and 9, the fixing hole 51 is formed by digging the ground 50 to a predetermined depth. Note that the fixing hole 51 is dug in a substantially cylindrical shape, but may be dug in a substantially prismatic shape. On two opposing side surfaces of the column 10B, in addition to the through hole 11 through which the level pin 15 can be inserted, a through hole 12 and an opening 13 are respectively formed. The through hole 12 is formed at a height position between the through hole 11 and the opening 13. Note that the number and position of the through holes 12 are not particularly limited as long as they are formed at positions filled with the foamed urethane 40 injected into the fixing hole 51. The opening 13 is formed by being cut out from the lower end of the column 10B. Note that the opening 13 is not limited to being cut out from the lower end of the column 10B, and it may be an opening on the side surface of the column above the lower end of the column 10B. Further, the through-hole 12 and the opening 13 are not limited to being formed on two opposing side surfaces of the column 10B, and may be formed on only one side surface, or may be formed on three or four side surfaces. As shown in FIG. 7, a lid member 20 is fixed to the side surface of the column 10B with tapping screws 25. Since the configuration of the lid member 20 is the same as that of the first embodiment, the same reference numerals are given and the description thereof is omitted.

[0023] Next, the process of fixing the column 10B to the ground 50 and constructing the fence 1 will be described with reference to FIGS. 8 and 9. As shown in FIG. 8(A), the column 10B is disposed above the fixing hole 51 formed in the ground 50, and as shown in FIG. 8(B), the lower end portion of the column 10B is inserted into the fixing hole 51 and installed. In FIG. 8, since the lower end of the column 10B is placed on the bottom surface of the fixing hole 51, a level pin is not used. When the depth dimension of the fixing hole 51 is large, similar to the first embodiment, the level pin 15 may be inserted into the through-hole 11 of the column 10B and this level pin 15 may be placed on the ground 50. Next, urethane resin is injected from between the fixing hole 51 and the column 10B. The urethane resin injected into the fixing hole 51 is filled from the opening 13 at the lower end of the column 10B to the inside of the column 10B as shown in FIG. 9. Also, the through-hole 12 portion is filled with urethane resin. The amount of urethane resin injected into the fixing hole 51 is preset to the amount that fills up to the upper surface of the fixing hole 51 when the urethane resin foams and cures to become the foamed urethane 40.

[0024] Next, as shown in FIGS. 7 and 9, the split lids 20A and 20B are fixed to the pillar 10B. Specifically, each of the split lids 20A and 20B is placed on the ground 50 and fixed to the side surface of the pillar 10B using tapping screws 25. If the level pin 15 is provided, each of the split lids 20A and 20B needs to be installed in such a direction that the level pin 15 is disposed at the positions of the drain holes 214 and 234. On the other hand, if the level pin 15 is not provided and the pillar 10B has a square planar shape, that is, the width dimensions of each side surface are the same, the orientations of the split lids 20A and 20B are not restricted. As the injected urethane resin foams and cures, the pillar 10B is fixed to the ground 50 via the foamed urethane 40. Next, in the same manner as in the first embodiment, the fence body 5 is fixed to the pillar 10B using brackets or the like. Thus, the construction of the fence 1 is completed.

[0025] [Effects of the Second Embodiment] Also in the second embodiment, the same effects as in the first embodiment can be achieved. Furthermore, since the lower end of the pillar 10B is installed at the bottom of the fixing hole 51, the pillar 10B can be installed without providing a level pin, and the workability can be improved. Also, since the opening 13 is formed in the pillar 10B, the urethane resin injected into the fixing hole 51 is also filled inside the pillar 10B from the opening 13, and the foamed urethane 40 is filled both inside and outside the pillar 10B, so the fixing strength of the pillar 10B can be improved. Also, since the through hole 12 is formed in the pillar 10B, the foamed urethane 40 inside and outside the pillar 10B is connected at the through hole 12 portion. Since this foamed urethane 40 functions as an anchor for preventing the pillar 10B from coming out, the fixing strength of the pillar 10B can be improved.

[0026] [Modification Example] The present invention is not limited to the fixing structure of the pillars 10 and 10B used as the supports of the fence 1, and can be used as the fixing structure of various pillars and supports installed outdoors, such as pillars of mail posts and delivery boxes. The resin cured product for fixing the column is not limited to the one composed of foamed urethane 40, and a non-foaming resin material may also be used. That is, it may be composed of a resin material that can be injected into the fixing hole in a fluid state, such as an epoxy resin or a urethane resin, and then cured. The base part where the fixing hole is formed is not limited to the concrete block 3 or the ground 50, and any part that can support the column arranged in the fixing hole via the resin cured product injected into the fixing hole is acceptable.

[0027] The lid member 20 is not limited to being fixed to the columns 10, 10B with tapping screws 25. For example, the lid member may be engaged and fixed to the base part such as the concrete block 3, or when installing the column 10B on the ground 50 as in the second embodiment, a plurality of protrusions may be formed from the lower end of the side surface part 23 of the lid member, and the lid member may be fixed by inserting these protrusions into the ground 50. The drainage part is not limited to the drainage holes 214, 234 where the level pins 15 can be arranged. For example, slits may be formed at the corner parts of the side surface part 23 or the like, and these slits may be used as the drainage part, or the height of the lower surface of the long side part 231 may be made higher than that of the lower surface of the short side part 232 to form a gap between the base part, and this gap may be used as the drainage part.

[0028] The lid member 20 is not limited to being composed of split lids 20A, 20B. For example, when attaching a fence body or the like after fixing the column alone, an integral lid member with an opening through which the column can be inserted may be inserted and attached from the upper end of the column or the like. Furthermore, the lid member is not limited to being composed of the two-split split lids 20A, 20B, and may be composed of split lids split into three or more parts. The configuration of the split lids 20A, 20B is not limited to the above embodiment. For example, although the fixing part 21 extends downward beyond the covering part 22 so that the lower ends of the fixing part 21 and the side surface part 23 are at the same height position, the lower end of the fixing part 21 may be set at a position above the lower end of the side surface part 23.

[0029] In the column 10 of the first embodiment, through holes 12 and openings 13 may be formed in the same manner as the column 10B of the second embodiment. The column 10B of the second embodiment may not be provided with the through hole 11. Furthermore, each column is not limited to a square tube shape, and may be a cylindrical column, a solid column instead of a hollow tube shape, or a column having an L-shaped or H-shaped cross section. The lid member may be formed according to the shape of the column.

[0030] [Summary of the Invention] The column fixing structure of the present invention includes a column, a base portion having a fixing hole into which a lower end portion of the column is inserted, a resin cured product filled in the fixing hole to fix the column, and a lid member provided on an upper surface of the base portion to cover an upper surface of the resin cured product, and the lid member is characterized by including a drainage portion capable of draining water that has entered between the resin cured product and the lid member. According to the present invention, since the column inserted into the fixing hole of the base portion is fixed with a resin cured product filled and cured in the fixing hole, the curing time can be shortened and the construction period can be shortened compared with the case of fixing with mortar. In addition, since the curable resin that becomes the resin cured product is lighter in weight and easier to handle than mortar, the workability can be improved. Further, although the resin cured product may have low weather resistance, in the present invention, since a lid member that covers the upper surface of the resin cured product is provided, it is possible to prevent the resin cured product from being deteriorated by being exposed to ultraviolet rays or the like, and the weather resistance can be improved. Furthermore, since the resin cured product is covered with the lid member and is not exposed to the outside, the design property of the fixed portion of the column can be improved. Furthermore, since a drainage portion is provided in the lid member, water that has entered from a gap between the column and the lid member or the like can be drained, and it is possible to prevent water from staying between the lid member and the resin cured product. For this reason, it is also possible to prevent water from staying between the lid member and the resin cured product, and the volume of the water increases due to freezing, causing the lid member to be deformed or the like and the resin cured product to be exposed to the outside, and it is possible to prevent a decrease in weather resistance and design property.

[0031] In the column fixing structure of the present invention, the lid member has a fixing portion fixed to the side surface of the column, a covering portion extending outward from the fixing portion to cover the upper surface of the resin cured product, and a side surface portion extending downward from the outer periphery of the covering portion to abut against the upper surface of the base portion. It is preferable that a drain hole serving as the drain portion is formed in the side surface portion. According to the present invention, the fixing portion can be brought into contact with the side surface of the column and can be easily fixed using tapping screws or the like. Further, since it has a side surface portion extending downward from the outer periphery of the covering portion, the covering portion can be disposed above the upper surface of the base portion, and a space can be secured between the upper surface of the base portion and the covering portion. For this reason, even if the resin cured product slightly overflows from the fixing hole of the base portion, it can be stored in the above space, and since it is not necessary to cut off the resin cured product that has overflowed from the fixing hole with a cutter or the like, the workability can also be improved. Furthermore, since a drain hole is formed in the side surface portion, rainwater or the like that has entered the above space can be reliably drained.

[0032] In the column fixing structure of the present invention, it is preferable that the lid member is constituted by combining a plurality of divided lids. According to the present invention, since the lid member is constituted by a plurality of divided lids, after injecting the curable resin into the fixing hole in which the column is installed, each divided lid can be easily attached to the column from the side of the column, and the workability of the construction work can be improved.

[0033] In the column fixing structure of the present invention, the column is provided with a level pin that is removably provided on the upper surface of the base portion to set the height position of the column, and it is preferable that the lid member has a drain hole through which the level pin is inserted and that also serves as the drain portion. According to the present invention, by placing a level pin attached to a column on the upper surface of a base portion, the height position of the column can be set. Therefore, it is not necessary to install the lower end of the column at the bottom of the fixing hole, and it is not necessary to flatten the bottom of the fixing hole, so the workability can be improved. Further, since a drain hole that can accommodate the level pin and also serves as a drain portion is formed in the lid member, the lid member can be installed with the level pin attached to the column. For this reason, the lid member can be installed immediately after injecting the curable resin into the fixing hole, and after the curable resin has hardened into a resin cured product, the level pin can be removed without removing the lid member, improving the workability of the construction work.

[0034] In the column fixing structure of the present invention, the column may be formed in a hollow cylindrical shape, the lower end of the column may be disposed above the bottom of the fixing hole, and an opening for filling the resin cured product may be formed inside the column. According to the present invention, since the lower end of the hollow cylindrical column is disposed above the bottom of the fixing hole, when the curable resin is injected into the fixing hole, the curable resin is also filled into the column from the lower end opening of the column, and the resin cured product is filled both inside and outside the column, so the fixing strength of the column can be improved.

[0035] In the column fixing structure of the present invention, the column may be formed in a hollow cylindrical shape, the lower end of the column may be installed at the bottom of the fixing hole, and an opening for filling the resin cured product may be formed inside the column in the range from the lower end of the column to the height position of the upper surface of the fixing hole. According to the present invention, since the lower end of the column is installed at the bottom of the fixing hole, the column can be installed without providing a level pin. Further, since an opening is formed in the range from the lower end of the hollow cylindrical column to the height position of the upper surface of the fixing hole, when the curable resin is injected into the fixing hole, the curable resin is also filled into the column from the opening, and the resin cured product is filled both inside and outside the column, so the fixing strength of the column can be improved.

[0036] In the column fixing structure of the present invention, the resin cured product is preferably composed of foamed urethane. According to the present invention, since the resin cured product can be filled into the fixing hole and the column by foaming, the amount of resin used can be reduced and the workability can be improved.
