Summary of the Invention

Problems to be Solved by the Invention

[0004] In a simple structure such as a carport, it is desired to stably support a support column portion that supports an upper structure portion such as a roof with a simple structure.

Means for Solving the Problems

[0005] The column support structure for solving the above problems includes a support column portion that supports an upper structure portion, and an embedded support structure that supports the support column portion. The embedded support structure includes a foundation member buried in the ground and a plurality of piles driven into the ground. The foundation member includes a main body portion, a column support portion disposed on the main body portion and supporting the support column portion, and a plurality of pile support portions disposed on the main body portion and supporting the piles at positions separated from the column support portion. Each of the pile support portions has an annular shape for supporting the pile in a state where the pile is inserted therethrough. The piles are inserted and supported by the pile support portions so as to be inclined with respect to the vertical direction, which is the standing direction of the support column portion, and extend in different directions from each other.

[0006] According to the above configuration, the piles are driven into the ground so as to extend in different directions from each other. Therefore, the buried support structure can stably support the column part because the state of the base member is less likely to be displaced.

[0007] In the above column support structure, the main body part may be configured to include a plurality of vertical members extending in the vertical direction and a horizontal member connecting the vertical members. According to the above configuration, since the base member is configured by connecting a plurality of vertical members arranged in a row with a horizontal member, the width direction intersecting the parallel arrangement direction of the vertical members can be configured to be narrow. As a result, the installation groove for installing the base member can also be configured to be narrow.

[0008] In the above column support structure, the plurality of vertical members may include a central vertical member and outer vertical members located on both sides of the central vertical member, and the column support part may be arranged on the central vertical member, and the pile support part may be arranged on the outer vertical member.

[0009] According to the above configuration, the base member is integrated with the ground through the piles by the outer vertical members on both sides of the central vertical member to which the vertical load is applied through the column part. Thereby, the base member can stably support the column part.

[0010] In the above column support structure, the outer vertical member may be a polygonal column member, and the pile support part may be arranged on at least one side surface of the outer vertical member. According to the above configuration, the piles can be driven in different directions from each other by using the side surface of the outer vertical member.

[0011] In the above column support structure, the main body part may be a frame member having a polygonal shape, the column support part may be arranged at the center where the diagonals of the frame member intersect, and is supported through a plurality of corner parts and connecting members of the frame member, and the pile support part may be arranged at at least two corner parts of the frame member.

[0012] According to the above configuration, in the frame-shaped base member, the column part is supported at the central part, and at the surrounding corner parts, it is integrated with the ground by piles. Thereby, the base member can stably support the column part.

[0013] In the above column support structure, the frame member may be provided with support protrusions formed of prisms protruding upward at at least two corner parts, and the pile support part may be configured to be arranged on at least one side surface of the support protrusion.

[0014] According to the above configuration, the pile support part can be arranged on the support protrusion. By providing the pile support part on the support protrusion, the pile support part can be made stronger. For example, when driving the pile or when the ground is displaced, etc., deformation and damage of the pile support part with respect to the support protrusion due to the displacement load applied to the pile support part and the pile can be suppressed.

[0015] In the above column support structure, the buried support structure may be further configured to include a plate member having a surface through which the column part passes and extending in a direction intersecting the column part. According to the above configuration, not only the base member but also the plate member can receive the earth pressure. Thereby, the buried support structure becomes stronger, and the column part can also be supported by the plate member.

[0016] In the above column support structure, the buried support structure may be further configured to include a plate member provided on the base member and having a surface extending in a direction intersecting the column part. According to the above configuration, not only the base member but also the plate member can receive the earth pressure. Thereby, the buried support structure becomes stronger.

[0017] In the above column support structure, the upper structure is, for example, a roof structure. According to the above configuration, the roof structure can be stably supported. In the above column support structure, the roof structure may be configured to include a solar power generation panel. According to the above configuration, even if the weight increases due to the provision of the solar power generation panel on the roof structure, the roof structure can be stably supported.

[0018] In the column support structure, the roof structure includes a base end portion supported by the column portion and a tip end portion on the side opposite to the base end portion. The tip end portion is located above the base end portion, and the column portion may be configured to be connected at the base end portion.

[0019] The column support structure is, for example, a carport. According to the above configuration, it can be used as a carport. For example, when a solar power generation panel is provided on the roof structure, it can function as a simple garage capable of charging an electric vehicle.

[0020] The buried support structure for solving the above problems is a buried support structure that supports a column portion supporting an upper structure, and includes a foundation member buried in the ground and a plurality of piles driven into the ground. The foundation member includes a main body portion, a column support portion disposed on the main body portion and supporting the column portion, and a plurality of pile support portions disposed on the main body portion and at a position separated from the column support portion for supporting the piles. Each of the pile support portions has an annular shape for supporting the pile in a state where the pile is inserted therethrough, and the piles are inserted and supported by the pile support portions so as to be inclined with respect to the vertical direction, which is the standing direction of the column portion, and extend in different directions from each other.

[0021] The foundation member for solving the above problems is a foundation member that constitutes a buried support structure for supporting a column portion supporting an upper structure, and includes a main body portion, a column support portion disposed on the main body portion and supporting the column portion, and a plurality of pile support portions disposed on the main body portion and at a position separated from the column support portion for supporting the piles. Each of the pile support portions has an annular shape for supporting the pile in a state where the pile is inserted therethrough, and is configured to insert and support the piles so as to be inclined with respect to the vertical direction, which is the standing direction of the column portion, and extend in different directions from each other.

[0022] The supporting method for solving the above problems is a column supporting method for supporting a column part that supports an upper structure. In an installation groove, a foundation member is arranged that includes a column supporting part for supporting the column part and a plurality of pile supporting parts for supporting the piles at positions separated from the column supporting part. The pile supporting part has an annular shape that can support the pile in a state where the pile is inserted therethrough. The piles are driven in a direction inclined with respect to the vertical direction, which is the standing direction of the column part, and in different directions from each other. The column part is connected to the column supporting part, and the installation groove is backfilled to support the column part.

Advantages of the Invention

[0023] According to the present invention, the column part that supports the upper structure can be stably supported with a simple structure.

Embodiments for Carrying Out the Invention

[0025] Hereinafter, the carport to which the present invention is applied will be described with reference to FIGS. 1 to 10. <Description of the Carport> As shown in FIGS. 1 and 2, the carport 1 as a column support structure is a parking lot with a simple structure and is equipped with charging facilities for the electric vehicle 1a. The carport 1 includes a column portion 2, a roof structure 3 as an upper structure installed on the upper portion of the column portion 2, and an embedded support structure 11 for integrating the column portion 2 with the ground.

[0026] In this embodiment, the roof structure 3 is supported by two column portions 2. A solar power generation panel 4 is installed on the upper surface of the roof structure 3. The roof structure 3 includes a first roof portion 5 and a second roof portion 6. The first roof portion 5 and the second roof portion 6 form a V shape. That is, the first roof portion 5 includes a base end portion 5a and a tip end portion 5b opposite to the base end portion 5a. And the tip end portion 5b is located above the base end portion 5a. The second roof portion 6 also includes a base end portion 6a and a tip end portion 6b opposite to the base end portion 6a. And the tip end portion 6b is located above the base end portion 6a. The base end portion 5a of the first roof portion 5 and the base end portion 6a of the second roof portion 6 are connected to form a V-shaped valley portion. The column portion 2 hangs down from the valley portion. Each roof portion 5, 6 is configured to be connected to the upper portion of the column portion 2 by a horizontal beam 7. Such a carport 1 has equipment components such as a transformer, a capacitor, a lighting fixture, a display panel, and a charging device installed in a roof space or the like (not shown).

[0027] Since the carport 1 has the solar power generation panel 4 and the equipment parts associated with the solar power generation panel 4 installed on the roof structure 3, it becomes heavier than the roof structure without the solar power generation panel 4 installed. Accordingly, the support column part 2 also becomes heavy by adopting a high-strength material and structure. The embedded support structure 11 in the present embodiment can stably support such a heavy support column part 2 and roof structure 3.

[0028] <First Embodiment> As shown in FIGS. 2 and 3, the lower part of each support column part 2 is integrated with the ground by the embedded support structure 11. The embedded support structure 11 includes a base member 12 and a pile 13. The base member 12 is installed in an installation groove 14 excavated on the ground surface GL.

[0029] The base member 12 includes a main body part 12a, a column support part 22, and a pile support part 24. The main body part 12a is composed of a polygonal column member. The main body part 12a is composed of, for example, a square steel pipe having a square column shape. The main body part 12a includes a central vertical member 15, a first outer vertical member 16, and a second outer vertical member 17. These vertical members 15, 16, 17 are arranged in the order of the first outer vertical member 16, the central vertical member 15, and the second outer vertical member 17. Or, they are arranged in the order of the second outer vertical member 17, the central vertical member 15, and the first outer vertical member 16. The main body part 12a further includes a first horizontal member 18 and a second horizontal member 19. The first horizontal member 18 connects the lower ends of the first outer vertical member 16, the central vertical member 15, and the second outer vertical member 17. The second horizontal member 19 is spaced above the first horizontal member 18 and connects the first outer vertical member 16, the central vertical member 15, and the second outer vertical member 17. The upper end of the central vertical member 15 is a support protrusion 21 that supports the support column part 2. The upper ends of the first outer vertical member 16 and the second outer vertical member 17 are support protrusions 21 that support the pile 13. As shown in FIG. 4, each support protrusion 21 is a square column-shaped protrusion and includes four side surfaces 21a, 21b, 21c, and 21d.

[0030] The support projection 21 on the central vertical member 15 is the column support portion 22 to which the lower end of the support column portion 2 is connected. The column support portion 22 is fixed by fitting the lower end of the support column portion 2 and fastening bolts. Further, the column support portion 22 is fixed to the lower end of the support column portion 2 via a bracket. The column support portion 22 is fixed by a combination of the lower end of the support column portion 2 and these fixing means. Note that the lower end of the support column portion 2 may be fitted into the hole of the column support portion 22 and fixed by bolt tightening.

[0031] A pair of brackets 23 are attached to the support projections 21 of the outer vertical members 16, 16. Each bracket 23 includes a main plate 23a, a pair of side plates 23b provided on both sides of the main plate 23a, and butting pieces 23c provided on the pair of side plates 23b. The main plate 23a is a rectangular plate that covers the opposing side surfaces 21a, 21c. The side plate 23b is a rectangular plate that half-covers the side surfaces 21b, 21d adjacent to the side surfaces 21a, 21c from the corner side.

[0032] <Pile support portion> A pile support portion 24 through which the pile 13 is inserted is arranged on the main plate 23a. The pile support portion 24 has an annular shape through which the pile 13 can be inserted. The insertion hole of the pile support portion 24 is sized such that the pile 13 fits snugly without rattling. Further, the insertion hole of the pile support portion 24 also functions as a guide hole having a length such that the driving direction is difficult to displace when driving the pile 13. In the first embodiment, the insertion hole of the pile support portion 24 is a circular hole. The pile support portion 43 is fixed to the bracket 23 by welding or the like.

[0033] The pile support portion 24 is inclined in one direction with respect to the vertical direction in which the insertion direction of the pile 13 is also the standing direction of the support column portion 2. As an example, the pile support portion 24 is inclined in a range greater than 0° and less than 45° with respect to the vertical direction in which the insertion direction of the pile 13 is also the standing direction of the support column portion 2. Further, the insertion direction of the pile 13 of the pile support portion 24 is inclined in one direction with respect to the ground surface GL. As an example, the pile support portion 24 is inclined in a range greater than 0° and less than 45° with respect to the ground surface GL in the insertion direction of the pile 13.

[0034] On one side plate 23b, a pile support portion 24 through which the pile 13 is inserted is also arranged. The pile support portion 24 arranged on one side plate 23b also has the same configuration as the pile support portion 24 arranged on the main plate 23a and has the same inclination.

[0035] One of the pair of brackets 23 is arranged from the direction of the side surface 21a, and the other bracket 23 is arranged from the direction of the side surface 21c. Then, the butting pieces 23c of the pair of brackets 23 are butted at the positions of the side surfaces 21b and 21d. And the pair of brackets 23 are joined by bolt tightening. Also, each main plate 23a is fixed to each of the side surfaces 21a and 21c by bolt tightening. Thus, one pile support portion 24 inclined in the same direction is arranged on each of the side surfaces 21a, 21b, 21c, and 21d.

[0036] Here, the pile 13 is a linear long member and is a slender round pile. The pile 13 is a wooden pile, a steel pipe pile, a concrete pile, or the like. The pile 13 is an existing pile. The pile 13 has an outer shape that can be inserted into the insertion hole of the pile support portion 24 without rattling. Each pile support portion 24 is set at an angle that does not interfere with, for example, the driven pile 13 or other members.

[0037] <Installation method> First, to install the support column portion 2, an installation groove 14 is excavated in the ground at the location where the buried support structure 11 is to be arranged. Then, a temporary support such as a support base for supporting the base member 12 in the installation groove 14 is provided, and the base member 12 is arranged on the support base. Here, the base member 12 is provided with a pile support portion 24 by fixing a pair of brackets 23 to the outer vertical members 16 and 17 of the main body portion 12a.

[0038] Next, the pile 13 is inserted into each pile support portion 24, and successively, the pile 13 is driven into the ground by a driving machine. Each pile 13 is driven until the pile head is near the end of the pile support portion 24. When driving the pile 13, the insertion hole of the pile support portion 24 functions as a guide hole in the driving direction. Thereby, the pile 13 is driven into the ground in a stable posture. When all the piles 13 are driven into the ground, at one support protrusion 21, the piles 13 are driven in different directions from each other and become inclined piles. Since the base member 12 is integrated with the pile 13 which is a square pile extending in four directions through the pile support portion 24, it is also integrated with the ground. Note that the pile 13 may be fixed to the pile support portion 24 by welding or the like after driving.

[0039] After that, the lower end of the support column portion 2 is fixed to the column support portion 22 of the base member 12. Then, the temporarily installed support base or the like is removed. After that, the installation groove 14 is backfilled with backfill soil mixed with a ground improvement material. Thereafter, the roof structure 3 is installed on the support column portion 2.

[0040] <Effects of the First Embodiment> The effects of the first embodiment will be described. (1-1) The buried support structure 11 is driven into the ground so that the piles 13 extend in different directions from each other. In the first embodiment, the piles 13 are driven obliquely in four different directions. Therefore, the buried support structure 11 can stably support the support column portion 2 by making it difficult for the state of the base member 12 to be displaced. That is, the buried support structure 11 has an inclined pile structure and a square pile structure. For this reason, the horizontal displacement in the base member 12, the support column portion 2, and thus the roof structure 3 can be suppressed. Also, the vertical displacement can be suppressed.

[0041] (1-2) When driving the pile 13, the pile support portion 24 guides the driving direction of the pile 13. Thereby, the pile 13 can be driven straight in a predetermined driving direction in the ground.

[0042] (1-3) The base member 12 is configured by connecting a plurality of vertical members 15, 16, 17 arranged in a row with horizontal members 18, 19. Therefore, the width direction intersecting the arrangement direction of the vertical members 15, 16, 17 can be configured to be narrow. As a result, the installation groove 14 for installing the base member 12 can also be configured to be narrow, so that the excavation work of the installation groove 14 can be simplified.

[0043] (1-4) The base member 12 is integrated with the ground through the piles 13 by the outer vertical members 16, 17 on both sides of the central vertical member 15 to which a vertical load is applied through the support column 2. Thereby, the base member 12 can stably support the support column 2.

[0044] (1-4) The base member 12 is provided with four pile support portions 24 on each of the outer vertical members 16, 17. And the four piles in each of the outer vertical members 16, 17 are driven obliquely in different directions. Thereby, the base member 12 can stably support the support column 2.

[0045] <Modification Example of the First Embodiment> The first embodiment can be implemented with the following modifications. The first embodiment and the following modification examples can be implemented in combination with each other within a technically non - conflicting range.

[0046] · In the main body portion 12a, the number of vertical members is not limited to three, and may be two or four or more. When there are two vertical members, it can be configured by providing a pile support portion 24 at the upper end of the vertical members and providing a column support portion 22 at the middle position of the horizontal member connecting the two vertical members. When there are four or more vertical members, the column support portion 22 and the pile support portion 24 may be provided at the upper end of the vertical members so that the pile support portion 24 is located outside the column support portion 22. When there are four or more vertical members, there may be a vertical member where neither the column support portion 22 nor the pile support portion 24 is arranged.

[0047] · The shape of the vertical member is not limited to a quadrangular prism. The vertical member may be a polygonal prism having three or more side surfaces such as a triangular prism, a pentagonal prism, or a hexagonal prism. In this case, the pile support portion 24 does not have to be provided on all side surfaces.

[0048] For example, if the pile support portions 24 are provided on at least two side surfaces of a vertical member having three or more side surfaces, piles can be driven into each vertical member in different directions from each other. Also, when providing the pile support portions 24 on a plurality of vertical members, it may be configured such that the pile support portions 24 are provided on one side surface of each vertical member. In this case, the piles 13 supported by the pile support portion 24 of one vertical member and the piles 13 supported by the pile support portion 24 of another vertical member may be driven in different directions.

[0049] · The main body portion 12a may be configured to have a rectangular shape with a pair of vertical members, an upper horizontal member connecting the upper ends of the pair of vertical members, and a lower horizontal member connecting the lower ends of the pair of vertical members. In this case, diagonal members connecting the diagonals may be provided like bracings. In this case, the pile support portions 24 will be arranged on the side surfaces of the vertical members and the horizontal members.

[0050] · In the outer vertical members 16, 17 of the square column, the directions (first direction) in which the piles 13 supported by the pile support portions 24 provided on the opposing side surfaces 21a, 21c extend may be the same. In this case, the directions in which the piles 13 supported by the pile support portions 24 provided on the opposing side surfaces 21b, 21d extend are made different (second direction).

[0051] · In the vertical member, the position where the pile support portion 24 is provided may be provided not at the upper end but at the lower end, or may be provided at an intermediate position between the upper end and the lower end. The position where the pile support portion 24 is provided may be an intermediate position between the upper end and the lower end.

[0052] <Second Embodiment> As shown in FIG. 6, the lower part of each support column portion 2 is integrated with the ground by an embedded support structure 31. The embedded support structure 31 includes a base member 32 and piles 33. The base member 32 is installed in an installation groove 34 excavated in the ground surface GL.

[0053] The base member 32 includes a frame member 32a having a rectangular shape, a column support portion 42, and a pile support portion 43. The frame member 32a forms a rectangular frame with a square steel pipe or an elongated flat plate having a square column shape. The frame member 32a includes a cross member 35 that is parallel to the long side and passes through the center of the short side. The column support portion 42 is formed at the center position where the diagonal lines of the frame member 32a intersect. The column support portion 42 is a support protrusion that extends upward from the center of the cross member 35. Each corner portion of the frame member 32a and the column support portion 42 are connected by a connecting member 36. Each connecting member 36 is a cross member that inclines toward the center connecting the upper end of each corner portion of the frame member 32a and the column support portion 42. Thereby, the column support portion 42 is firmly arranged at the center of the frame member 32a. The column support portion 42 is a through hole into which the lower end of the column portion 2 is fitted and fixed by bolting or the like.

[0054] In addition, at each corner portion of the frame member 32a, a support protrusion 37 having a square column shape is provided. Each support protrusion 37 includes four side surfaces 37a, 37b, 37c, and 37d. Among the side surfaces 37a, 37b, 37c, and 37d, pile support portions 43 are arranged on the side surfaces 37a, 37b, and 37c. The pile support portion 43 has an annular shape through which the pile 33 can be inserted. The insertion hole of the pile support portion 43 is sized such that the pile 33 fits snugly without rattling. Also, the insertion hole of the pile support portion 43 functions as a guide hole having a length such that the driving direction is less likely to be displaced when driving the pile 33. In the second embodiment, the insertion hole of the pile support portion 43 is a square hole. The pile support portion 43 is fixed to the side surfaces 37a, 37b, and 37c by welding or the like.

[0055] The pile support portion 43 is inclined in one direction with respect to the vertical direction in which the insertion direction of the pile 33 is also the standing direction of the column portion 2. As an example, the pile support portion 43 is inclined in a range greater than 0° and less than 45° with respect to the vertical direction in which the insertion direction of the pile 33 is also the standing direction of the column portion 2. Also, the insertion direction of the pile support portion 43 is inclined in one direction with respect to the ground surface GL. As an example, the pile support portion 43 is inclined in a range greater than 0° and less than 45° with respect to the ground surface GL in the insertion direction of the pile 33.

[0056] Here, the pile 33 is a long linear member and is an elongated square prism. The pile 33 has an outer shape that can be inserted into the insertion hole of the pile support portion 43 without rattling. Each pile support portion 43 is set at an angle such that it does not interfere with other driven piles 33 or other members. Note that since the pile support portion 43 on the side surface 37d interferes with the connecting member 36, the pile 33 is not driven. The support protrusion 37 has the pile 33 driven into the pile support portions 43 on the three side surfaces 37a, 37b, and 37c. Of course, the pile support portion 43 on the unused side surface 37d may be omitted.

[0057] <Installation method> First, to install the support column portion 2, an installation groove 14 is excavated in the ground at the location where the buried support structure 11 is to be placed. Then, a temporary support such as a support base for supporting the base member 12 in the installation groove 14 is provided, and the base member 32 is placed on the support base.

[0058] Next, the pile 33 is inserted into each pile support portion 43, and continuously, the pile 33 is driven into the ground by a driving machine. Each pile 33 is driven until the pile head is near the end of the pile support portion 43. When driving the pile 33, the insertion hole of the pile support portion 43 functions as a guide hole in the driving direction. Thereby, the pile 33 is driven into the ground in a stable posture. When all the piles 33 are driven into the ground, in one support protrusion 37, the piles 33 are driven in different directions from each other and become inclined piles. Since the base member 32 is integrated with the pile 33 through the pile support portion 43, it is also integrated with the ground.

[0059] After that, the lower end of the support column portion 2 is fixed to the column support portion 42 with respect to the base member 32. Then, the temporarily provided support base etc. are removed. After that, the installation groove 14 is backfilled. Thereafter, the roof structure 3 is installed on the support column portion 2.

[0060] <Effects of the second embodiment> The effects of the second embodiment will be described. (2-1) The frame-shaped base member 32 supports the column part 2 with the column support part 42 at the central part, and is integrated with the ground by the piles 33 at the corner parts around it. Thereby, the base member 32 can stably support the column part 2.

[0061] (2-2) A pile support part 43 is arranged on the support projection part 37. The pile support part 43 provided on the support projection part 37 has a stronger attachment. For example, when driving the pile 33 or when the ground is displaced, etc., deformation or breakage of the pile support part 43 with respect to the support projection part 37 due to the displacement load applied to the pile support part 43 and the pile 33 can be suppressed.

[0062] <Modification Example of the Second Embodiment> The second embodiment can be implemented with the following modifications. The second embodiment and the following modification examples can be implemented in combination with each other within a technically non - conflicting range.

[0063] · The shape of the frame member 32a may be a polygonal shape such as a triangular shape, a pentagonal shape, or a hexagonal shape.
