Summary of the Invention

Problems to be Solved by the Invention

[0007] However, in the technology disclosed in Patent Document 1, the outer diameter of the new pole is made smaller than the inner diameter of the base of the existing pole to be cut, and the new pole is inserted into the hollow part of the remaining base after cutting and erected. However, there is a risk that the new pole will be fixed in a tilt relative to the ground. Furthermore, even if the pole adjustment fitting disclosed in Patent Document 2 is used, it is necessary to fix the pole adjustment fitting to the cylindrical structure using bolts or the like.

[0008] Therefore, the present invention aims to provide a support column and a method for securing the support column that can be easily and appropriately fixed to the ground or floor surface. [Means for solving the problem]

[0009] A support column according to one aspect of the present invention is a cylindrical support column fixed to the ground or floor surface, comprising: a support column body; at least two or more mounting portions formed on the peripheral wall of the support column body such that there is a gap between them and the peripheral wall; mounting members that can be attached to each mounting portion so as to be inserted into the gap along the axial direction of the support column body; and rod-shaped adjusting members that adjust the inclination of the support column body with respect to the ground or floor surface via the mounting members attached to each mounting portion.

[0010] In the above embodiment, the mounting member has a first component which is inserted into the gap and is positioned between the peripheral wall of the support body and the mounting portion to hold a temporary fixing member, and a second component which is formed in a direction perpendicular to the axial direction of the support body when attached to the mounting portion and has a hole into which an adjustment member is inserted, and the temporary fixing member may be positioned between the first component and the peripheral wall of the support body and between the first component and the mounting portion, at least one of these, when the mounting member is attached to the mounting portion.

[0011] In the above embodiment, the mounting member has a first component which is inserted into the gap and positioned to hold a temporary fixing member between the peripheral wall of the support column body and the mounting portion; a second component which is formed in a direction perpendicular to the axial direction of the support column body when attached to the mounting portion and has a hole for inserting an adjustment member; and two side wall portions which are formed at both ends of the first component which extend along the second component, and each of the two side wall portions may have a groove portion which is aligned with the axial direction of the support column body so as to sandwich the mounting portion when the temporary fixing member is positioned between the first component and the mounting portion.

[0012] In the above embodiment, the temporary fixing member may include a spring member.

[0013] In the above embodiment, the spring member may be a leaf spring.

[0014] In the above embodiment, the first component has a through hole, and the temporary fixing member may include a spring portion disposed between the first component and the peripheral wall of the support body or between the first component and the mounting portion, and a mating portion that spans over the first component from the spring portion and mats into the through hole from the opposite side.

[0015] In the above embodiment, each of the two side wall portions may include an inclined portion that is formed to slope as it moves away from the first component.

[0016] In the above embodiment, each of the two side wall portions may have a greater width on the opposite side of the groove than on the side of the first component, in the region where the groove is formed.

[0017] In the above embodiment, the mounting portion has connecting portions at both ends that are connected to the peripheral wall of the support column body along the axial direction of the support column body, so as to form a gap, and the connecting portions may be longer than the central portion of the mounting portion in the axial direction of the support column body, where a gap is formed between the connecting portion and the peripheral wall of the support column body.

[0018] In the above aspect, in a state where the attachment member is attached to the attachment portion, it may be temporarily fixed to the support column main body using a screw.

[0019] A method for fixing a support column according to an aspect of the present invention is a method for fixing the support column in the above aspect to the ground or the floor surface. The method includes disposing the support column main body in a recess formed in the ground or the floor surface, adjusting the inclination of the support column main body with respect to the ground or the floor surface by supporting the support column main body against the ground or the floor surface by an adjustment member in a state where attachment members are attached to at least two or more attachment portions respectively, and filling the recess with a filler and curing it to fix the support column to the ground or the floor surface.

[0022] The embodiments of the present invention will be described below in detail with reference to the drawings. The embodiments described below are merely examples of how to implement the present invention and are not intended to limit the scope of the invention. Furthermore, to facilitate understanding of the explanation, the same reference numerals are used for identical components in each drawing whenever possible, and redundant explanations may be omitted.

[0023] <First Embodiment> Figure 1 shows how a support column 100 according to the first embodiment of the present invention is fixed to the ground. As shown in Figure 1, a support column 10, which was fixed to the ground with a portion buried in it, is cut at the base, and a support column 100 is to be fixed to the remaining portion 11 of the support column 10.

[0024] The support column 10 was originally fixed in place with a portion of it buried in the ground, and for example, it was equipped with a light fixture such as an LED at the top and functioned as lighting for roads and parks. The support column 10 is cylindrical in shape, and cables or the like may be arranged in its internal space.

[0025] The support column 100 comprises a support column body 110 and a mounting member 120 (including an adjustment member 130) attached to the support column body 110, and is intended to be replaced, for example, due to deterioration of the support column 10 over time. The support column body 110 is, for example, cylindrical in shape, and the outer diameter of the cylindrical shape is smaller than the inner diameter of the support column 10, so that it can be inserted into the remaining portion 11 of the cut support column 10. Furthermore, cables for functioning as lighting may be arranged in the cylindrical internal space of the support column body 110.

[0026] Since the support column 10 was originally embedded and fixed in the ground, the remaining portion 11 of the support column 10 is firmly fixed to the ground. Therefore, the newly installed support column 100 is firmly fixed to the ground by being connected to the remaining portion 11, for example, using mortar.

[0027] The following describes in detail a specific example of properly fixing the support column 100 to the ground using the mounting member 120 attached to the support column body 110.

[0028] Figure 2 is a diagram illustrating a mounting portion 111 for attaching a mounting member 120 to a support column body 110 according to a first embodiment of the present invention. As shown in Figure 2, the mounting portion 111 is formed on the peripheral wall of the support column body 110.

[0029] At least two mounting portions 111 are formed on the peripheral wall of the support column body 110, and preferably, for example, three or four may be formed at equal intervals.

[0030] The mounting portion 111 is formed on the peripheral wall of the support column body 110 so as to have a gap 112 between itself and the peripheral wall. For example, the mounting portion 111 has connecting portions 113 at both ends that are connected to the peripheral wall of the support column body 110 along the axial direction of the support column body 110, and is connected to the support column body 110 by welding or the like.

[0031] Furthermore, the connecting portion 113 may be formed to be longer than the central portion of the mounting portion 111, which forms a gap 112 between it and the peripheral wall of the support column body 110, in the axial direction of the support column body 110.

[0032] Specifically, the mounting portion 111 is connected to the support column body 110 at both ends by connecting portions 113, the upper region of the central part is configured as a plate shape with a gap 112 between it and the peripheral wall of the support column body 110, and the lower region of the central part is configured to have a notched area. The upper portion of the mounting member 120 fits into the plate shape of the mounting portion 111, and the lower portion of the mounting member 120 is positioned in the notched area of ​​the mounting portion 111.

[0033] Figure 3 is a diagram illustrating a mounting member 120 attached to a mounting portion 111 in a support column body 110 according to a first embodiment of the present invention. As shown in Figure 3, the mounting member 120 has a first component 121, a second component 122, a hole 123, a side wall 124, and a groove 125.

[0034] The first component 121 is positioned along the axial direction of the support column body 110 and is inserted into the gap 112 of the support column body 110. As a result, a portion of the first component 121 abuts against the peripheral wall of the support column body 110, and the surface of the first component 121 opposite to the surface abutting against the peripheral wall of the support column body 110 indirectly abuts against the mounting portion 111 formed on the support column body 110 via the spring member 140.

[0035] The second component 122 is positioned perpendicular to the axial direction of the support column body 110 and is provided with a hole 123. For example, when the support column 100 is positioned perpendicular to the ground, the second component 122 will be positioned parallel to the ground.

[0036] A rod-shaped adjustment member 130 is inserted into the hole 123. For example, the adjustment member 130 is a bolt or screw, and its tip contacts the ground to adjust the inclination of the support column body 110 relative to the ground. Specifically, the inclination of the support column body 110 is adjusted by adjusting the amount (height) of the adjustment member 130 that protrudes downward (towards the ground) from the hole 123 of the second component 122 in the mounting member 120 attached to the mounting portion 111 formed in at least two locations on the peripheral wall of the support column body 110.

[0037] The side wall portion 124 is formed to extend along the second component portion 122 at both ends of the first component portion 121. Furthermore, each side wall portion 124 has a groove portion 125 formed along the axial direction of the support column body 110 so as to sandwich the mounting portion 111 when the mounting member 120 is attached to the support column body 110. That is, the mounting member 120 is fitted and attached to the mounting portion 111 by sliding the groove portion 125 along the axial direction of the support column body 110 to match the plate shape of the mounting portion 111. Furthermore, it is preferable that in the region of the side wall portion 124 in which the groove portion 125 is formed, the width on the opposite side of the groove portion 125 is larger (W1 > W2) than the width on the side of the first component portion 121.

[0038] Figure 4 shows how the mounting member 120 is attached to the mounting portion 111 of the support column body 110 according to the first embodiment of the present invention. As shown in Figure 4, the first component 121 of the mounting member 120 is inserted into the gap 112 formed between the mounting portion 111 and the peripheral wall of the support column body 110, and the spring member 140 (temporary fixing member) is placed between them. In this way, the mounting member 120 is firmly attached to the mounting portion 111. Here, the spring member 140 is used as a temporary fixing member to fix the mounting member 120 to the mounting portion 111, but it is not limited to this, and for example, a wedge, a cushioning material such as a packing, and an adhesive may be used.

[0039] Furthermore, with the first component 121 of the mounting member 120 inserted into the gap 112 formed between the mounting portion 111 and the peripheral wall of the support column body 110, the mounting member 120 and the mounting portion 111 (support column body 110) may be temporarily fixed using, for example, screws. In this case, the mounting member 120 and the mounting portion 111 (support column body 110) only need to be provided with through holes for screws.

[0040] Figure 5 is a side view showing the mounting portion between the mounting portion 111 and the mounting member 120 in the support body 110 according to the first embodiment of the present invention. As shown in Figure 5, the first component 121 of the mounting member 120 is inserted into the gap 112, and the spring member 140 is further positioned therein.

[0041] For example, the spring member 140 is a leaf spring and is positioned between the first component 121 and the mounting portion 111. The first component 121 and the mounting portion 111 act in a repulsive direction, causing the first component 121 to be pressed against the support column body 110. As a result, the mounting member 120 is firmly attached to the support column body 110.

[0042] Furthermore, because the groove 125 is positioned to fit into the plate shape of the mounting portion 111, the mounting member 120 is attached to the support column body 110 more stably.

[0043] Furthermore, when supporting the support column body 110 with the tip of the adjustment member 130 in contact with the ground and adjusting the inclination of the support column body 110 relative to the ground, a load is applied to the mounting member 120 and the adjustment member 130 according to the magnitude of the inclination. For example, since the groove 125 of the mounting member 120 fits into the plate shape of the mounting part 111, if the support column body 110 is tilted, a greater load is applied to the area of ​​the mounting member 120 where the groove 125 is formed, via the groove 125, than to the side on the first component 121. Then, when trying to straighten the tilted support column body 110 so that it is perpendicular to the ground, the adjustment member 130 of the mounting member 120 attached to the side of the tilted support column body 110 is adjusted. In other words, in the region where the groove 125 of the mounting member 120 is formed, the portion opposite to the first component 121 side via the groove 125 must transmit an adjusting force that attempts to straighten the inclined support column body 110 so that it is perpendicular to the ground, and therefore needs to have sufficient strength to withstand this force. For this reason, it is preferable that the side wall portion 124 of the mounting member 120 is formed such that the side opposite to the groove 125 has a larger width (W1 > W2).

[0044] Furthermore, the side wall portion 124 may be formed such that, in the area of ​​the second component 122 corresponding to the region where the hole portion 123 is formed, the axial distance (height) of the support column body 110 is smaller than the area where the groove portion 125 is formed. This makes it easier for the worker to operate the adjustment member 130, which is inserted into the hole portion 123, when adjusting the amount of protrusion toward the ground, as the upper part of the adjustment member 130 is exposed more than the side wall portion 124. Here, for example, the side wall portion 124 includes an inclined portion in the area of ​​the second component 122 where the hole portion 123 is formed, and is formed to be inclined as it moves away from the first component 121.

[0045] Figure 6 shows the arrangement of the spring member 140 on the mounting member 120. As shown in Figure 6, the spring member 140 is positioned to hook onto the first component 121 of the mounting member 120.

[0046] For example, the spring member 140 may be formed smaller than the thickness of the first component 121 at the upper end surface of the first component 121 in the portion that hooks onto the first component 121. Specifically, when the spring member 140 is positioned to hook onto the first component 121 by resting it on the upper end surface of the first component 121, if it is formed smaller than the thickness of the first component 121 at the upper end surface of the first component 121, it will not contact the entire upper end surface, and one side will be floating. In other words, the spring member 140 is positioned so as the first component 121 moves away from the insertion starting position of the first component 121, which is inserted into the gap 112 of the support body 110.

[0047] As a result, with the spring member 140 positioned so as to rest on the upper end surface of the first component 121 and hooked onto the first component 121, the first component 121 is inserted into the gap 112 of the support column body 110, and as the first component 121 moves away from the insertion starting position, the repulsive force of the spring member 140 acts, so that the mounting member 120 is more firmly attached to the mounting portion 111 of the support column body 110.

[0048] Figure 7 shows a support column 100 according to the first embodiment of the present invention, fixed vertically to the ground G. As shown in Figure 7, the support column body 110 is supported by the ground G by an adjustment member 130 using an attachment member 120 attached to the attachment portion 111 of the support column body 110.

[0049] For example, mounting members 120 are attached to four mounting portions 111 formed on the peripheral wall of the support column body 110. The support column body 110 is then supported by four adjustment members 130 that protrude downward (towards the ground G) from the holes 123 of the second component 122 of the mounting member 120. Here, the inclination of the support column body 110 can be adjusted by adjusting the amount of protrusion (height) of the four adjustment members 130 that protrude downward (towards the ground G) from the holes 123 of the second component 122, so that it is, for example, perpendicular to the ground G.

[0050] Figure 8 is a flowchart showing the process flow of a support post fixing method M100 for fixing a support post 100 to the ground according to a first embodiment of the present invention. As shown in Figure 8, the support post fixing method M100 includes steps S110 to S140.

[0051] In step S110, the mounting members 120 are attached to the mounting portions 111 on the main support column 110. For example, four mounting portions 111 may be formed on the peripheral wall of the main support column 110, and the mounting members 120 may be attached to each of them by inserting the first component 121, on which the spring member 140 is placed, into the gap 112.

[0052] In step S120, the support column body 110, to which the mounting member 120 was attached to the mounting portion 111 in step S110, is placed in the remaining portion 11 where the base of the existing support column 10 was cut. For example, the outer diameter of the new support column body 110 is smaller than the inner diameter of the existing support column 10, and the support column body 110 is inserted into the remaining portion 11 of the cut support column 10.

[0053] In step S130, the tilt of the support column body 110, which was positioned in step S120, is adjusted using the adjustment members 130. For example, by adjusting the amount of protrusion (height) of the four adjustment members 130 that protrude downward (towards the ground G) from the hole 123 of the second component 122 of the mounting member 120, the tilt of the support column body 110 is adjusted to make it perpendicular to the ground G.

[0054] In step S140, the support column body 110, which was positioned perpendicular to the ground G in step S130, is filled with a filler and hardened. For example, the support column 100 is fixed to the ground G by filling the recess (remaining portion 11) where the existing support column 10 was embedded in the ground G with mortar or the like and hardening it.

[0055] Furthermore, the filler material is not limited to mortar, but may also be cement, concrete, or resin-based materials such as epoxy. In addition, the filler material may be placed not only in the recess (remaining portion 11) below the ground G, but also above the ground G, covering the peripheral wall portion of the support column body 110, the mounting portion 111, and the mounting member 120.

[0056] As described above, according to the first embodiment of the present invention, the support column 100 and support column fixing method M100, the mounting member 120 is attached to the mounting portion 111 of the support column body 110, and the tilt of the support column body 110 is adjusted by the adjustment member 130. As a result, the support column 100 can be easily fixed perpendicular to the ground G.

[0057] Furthermore, since the mounting member 120 is not pre-formed on the support column body 110, for example, when transporting the support column body 110, there is less part protruding from the peripheral wall of the support column body 110, making it easy to handle and transport as cargo. At the construction site, the mounting member 120 can be easily attached to the mounting portion 111 on the support column body 110 using a sliding mechanism, and can be firmly attached by using the spring member 140.

[0058] Furthermore, the mounting member 120 may have a shape other than that described with reference to Figure 4. Figure 9 is a diagram illustrating other mounting members that are attached to the mounting portion 111 of the support column body 110 according to one embodiment of the present invention.

[0059] As shown in Figure 9(A), the mounting member 220, like the mounting member 120 described in Figure 4, has a first component 121 that is inserted into the gap 112 of the support column body 110, and a groove 125 is formed along the axial direction of the support column body 110 so as to sandwich the mounting portion 111 (plate shape) of the support column body 110. The mounting member 220 differs from the mounting member 120 described in Figure 4 in that the side wall portion 224 forms an inclined portion from the tip of the groove 125.

[0060] As shown in Figure 9(B), the mounting member 320, like the mounting member 120 described in Figure 4, has a first component 121 that is inserted into the gap 112 of the support column body 110, but does not have a groove 125 formed along the axial direction of the support column body 110 so as to sandwich the mounting portion 111 (plate shape). If the mounting member 320 is stably attached to the mounting portion 111 of the support column body 110 by being inserted into the gap 112 of the support column body 110, and has sufficient strength to transmit and withstand the adjusting force that attempts to raise the tilted support column body 110 to be perpendicular to the ground, then a configuration such as a side wall portion 324 without a groove may be acceptable.

[0061] In this embodiment, the spring member 140 was positioned between the first component 121 and the mounting portion 111, but it may also be positioned between the first component 121 and the peripheral wall of the support column body 110, or even in both locations.

[0062] Furthermore, in this embodiment, the first component 121 has been described as having a plate shape perpendicular to the two side wall portions 124 (224, 324) and directly or indirectly contacting the peripheral wall of the support column body 110 as a whole, but it is not limited to this. For example, it may be composed of two rod shapes at positions corresponding to the two side wall portions 124 (224, 324), or at the ends of the two side wall portions 124 (224, 324). That is, the first component composed of two rod shapes may have a hollow central region compared to the plate shape described above, and the two rod shapes may directly or indirectly contact the peripheral wall of the support column body 110, and a corresponding temporary fixing member may be provided.

[0063] Furthermore, although the support column body 110 was cylindrical in this embodiment, it is not limited to this, and may be rectangular or other shapes, for example, as long as it fits within the inner diameter of the existing support column 10 to be cut.

[0064] Furthermore, although the support column 100 was fixed to the ground in this embodiment, it may also be fixed to the floor (rooftop) of a constructed highway, bridge, or other structure.

[0065] <Second Embodiment> Next, a second embodiment of the present invention will be described. In this embodiment, the same configuration and content as in the first embodiment will be omitted or simplified in the description, and the differences from the first embodiment will be described in detail.

[0066] Figure 10 is a side view showing the mounting portion between the mounting portion 111 and the mounting member 120' in the support column body 110 according to the second embodiment of the present invention. As shown in Figure 10, the configuration of the mounting portion 111 and the mounting member 120' in the support column body 110 is generally the same as that of the first embodiment (Figure 5).

[0067] In the example shown in Figure 5 of the first embodiment, a first component 121 holding a spring member 140 is positioned between the peripheral wall of the support column body 110 and the mounting portion 111. More specifically, the spring member 140 abuts against the mounting portion 111, and the reaction force of the spring member 140 causes the first component 121 to abut against the peripheral wall of the support column body 110. In other words, the first component 121 holding the spring member 140 is sandwiched between the support column body 110 and the mounting portion 111, and the frictional force between the spring member 140 and the mounting portion 111, and the frictional force between the first component 121 and the peripheral wall of the support column body 110, temporarily fixes the mounting member 120 and the mounting portion 111 (support column body 110). Here, there may be a gap between the mounting portion 111 and the groove portion 125.

[0068] On the other hand, in the example shown in Figure 10 of the second embodiment, there is no gap between the mounting portion 111 and the groove portion 125, and the groove portion 125 of the mounting member 120 is fitted into the mounting portion 111, so that the spring member 140 held by the first component 121 is in contact with the mounting portion 111. In other words, the reaction force of the spring member 140 prevents a gap from being created between the mounting portion 111 and the groove portion 125, and the spring member 140 held by the first component 121 is placed in the groove portion 125, and the mounting portion 111 is sandwiched in the groove portion 125, and the mounting member 120' and the mounting portion 111 (support column body 110) are temporarily fixed by the frictional force between the mounting portion 111 and the groove portion 125, and the frictional force between the mounting portion 111 and the spring member 140. Here, there may be a gap between the first component 121 of the mounting member 120' and the peripheral wall of the support column body 110.

[0069] <Third Embodiment> Next, a third embodiment of the present invention will be described. In this embodiment, the same configuration and content as in the first embodiment will be omitted or simplified in the description, and the differences from the first embodiment will be described in detail.

[0070] Figure 11 is a diagram illustrating the mounting member 420 and spring member 440 according to the third embodiment of the present invention, and Figure 12 is a diagram showing the spring member 440 attached to the mounting member 420 according to the third embodiment of the present invention. As shown in Figure 11, the mounting member 420 has a through hole 421 in the first component 121, and the spring member 440 has a leaf spring portion 441 and a mating portion 442.

[0071] The spring member 440 is positioned so as to hook onto the upper part of the first component 121, with the leaf spring portion 441 positioned between the first component 121 and the mounting portion 111 (groove portion 125). The fitting portion 442 then fits into the through hole 421 of the mounting member 420 from the opposite side, across the upper part of the first component 121 from the leaf spring portion 441. As a result, the spring member 440 is stably positioned, and the mounting member 120 and the mounting portion 111 (support column body 110) can be temporarily fixed more appropriately.

[0072] Furthermore, even if the leaf spring portion 441 is positioned between the first component 121 and the peripheral wall of the support column body 110, and is positioned to hook onto the upper part of the first component 121, the engagement portion 442 will engage with the through hole 421 of the mounting member 420 from the opposite side, thus achieving the same effect.

[0073] The embodiments described above are provided to facilitate understanding of the present invention and are not intended to limit its interpretation. The elements, arrangement, materials, conditions, shapes, and sizes of the embodiments are not limited to those exemplified and can be modified as appropriate. Furthermore, it is possible to partially substitute or combine the configurations shown in different embodiments. [Explanation of Symbols]
