Summary of the Invention

Problems to be Solved by the Invention

[0004] In this type of support structure, since a welding process is required for connecting the support and the bottom plate, there is a risk of problems such as taking time and effort in manufacturing and difficulty in ensuring dimensional accuracy and strength due to individual differences (variations).

[0005] Therefore, one of the problems of the present invention is to provide an improved and novel support structure that, for example, does not require a welding process in the connection between the support and the bottom plate and can avoid the problems caused by the welding process.

Means for Solving the Problems

[0006] The column structure of the present invention includes, for example, a first member placed on an installation surface, a supported portion supported by the first member in a state of extending across the installation surface on the side opposite to the installation surface with respect to the first member, a pressed portion facing the side opposite to the installation surface, a columnar member having these, a second member having a first pressing portion facing the pressed portion, a coupled portion provided on the first member or provided on an embedded member at least partially embedded under the installation surface, a second pressing portion located on the side opposite to the installation surface with respect to a part of the second member, and a coupling member having a coupling portion coupled to the coupled portion. With the coupling of the coupled portion and the coupling portion, the second pressing portion presses the second member in a direction approaching the installation surface, and the first pressing portion presses the pressed portion in a direction approaching the installation surface.

DETAILED DESCRIPTION OF THE INVENTION

[0008] Exemplary embodiments of the present invention are disclosed below. The configurations of the embodiments shown below, as well as the actions and results (effects) obtained from such configurations, are examples. The present invention can also be realized by configurations other than those disclosed in the following embodiments. Further, according to the present invention, it is possible to obtain at least one of various effects (including derivative effects) obtained by the following configurations.

[0009] In this specification, ordinal numbers may be given for convenience in distinguishing directions, positions, members, parts, mechanisms, etc. Also, ordinal numbers do not indicate priorities or orders, nor do they specify numbers.

[0010] In each figure, arrows indicating directions are drawn. The X direction, Y direction, and Z direction intersect each other and are substantially orthogonal. The Z direction or the opposite direction of the Z direction may also be referred to as the extending direction or longitudinal direction of the columnar member 30. The X direction and Y direction are substantially along the installation surface P as a plane. When the installation surface P is a substantially horizontal plane, the X direction and Y direction are substantially along the horizontal direction, and the Z direction is substantially along vertically upward. However, this is an example, and the installation surface P may be inclined with respect to the horizontal plane, and the Z direction may also be inclined with respect to vertically upward. Also, the dashed-dotted line extending in the Z direction in each figure is the central axis Ax of the columnar member 30.

[0011] [First Embodiment] [Support Structure] FIG. 1 is a perspective view of a column structure 100A (100) according to the first embodiment. As shown in FIG. 1, the column structure 100 includes a bottom plate 10A (10), a pressing member 20A (20), a columnar member 30A (30), a coupling mechanism 40, and an intervening member 50A (50). The column structure 100 is configured such that, with the columnar member 30 extending in the Z direction intersecting the installation surface P, the assembly of the columnar member 30, the bottom plate 10, the pressing member 20, and the intervening member 50 can be fixed on the installation surface P by the coupling mechanism 40. The column structure 100 fixedly installed on the installation surface P supports the object to be supported 200 at a position away from the installation surface P in the Z direction. The installation surface P is, for example, the upper surface of a concrete floor. The object to be supported 200 is, for example, a push button device. The push button device has a housing 201 and a push button 202 supported to be immersible in the housing 201, and can output an electrical signal or switch an electrical connection of a circuit in response to a pressing operation on the push button 202. Note that the object to be supported 200 is not limited to that shown in FIG. 1, and may be other input devices, display devices, audio output devices, etc., or may be a plate, a box, etc. The specifications such as the size, shape, size, and weight of the object to be supported 200 can also be variously changed. The object to be supported 200 may be supported by a plurality of column structures 100 installed in parallel. Also, the plurality of column structures 100 may form a fence.

[0012] Figure 2 is an enlarged view of the lower part of the support structure 100A (100). On the installation surface P, a bottom plate 10, an intervening member 50, and a pressing member 20 are placed in this order. In this embodiment, as an example, the coupling mechanism 40 is an anchor bolt assembly having an anchor bolt 41 and a nut 42. The anchor bolt 41 is partially buried under the installation surface P. The nut 42 is located on the side opposite to the installation surface P with respect to the bottom plate 10, the intervening member 50, and the pressing member 20. In the coupling mechanism 40, by tightening the nut 42 with respect to the anchor bolt 41 and moving it in the opposite direction of the Z direction, the nut 42 presses the pressing member 20, the intervening member 50, and the bottom plate 10 in the opposite direction of the Z direction toward the installation surface P. Further, the pressing member 20 is engaged with the columnar member 30 through an engagement structure described later. Therefore, the nut 42 presses the columnar member 30 in the opposite direction of the Z direction toward the bottom plate 10 through the pressing member 20 and the engagement structure. That is, in this embodiment, the nut 42 presses all the members constituting the support structure 100 toward the installation surface P. The bottom plate 10 is an example of a first member, and the pressing member 20 is an example of a second member. Further, the anchor bolt 41 is an example of an embedded member. The nut 42 is an example of a coupling member having a second pressing portion.

[0013] Figure 3 is an exploded perspective view of the support structure 100A (100). The columnar member 30A has a hollow square columnar shape, in other words, a rectangular tubular shape. That is, the cross section of the outer peripheral surface 30b of the columnar member 30A intersecting the Z direction has a square shape with rounded corners. Further, an end face 30a1 and a protrusion 30a2 are provided at an end 30a in the longitudinal direction (opposite direction of the Z direction) of the columnar member 30. The end face 30a1 faces the opposite direction of the Z direction, intersects the Z direction, and is substantially orthogonal. Further, the columnar member 30A has a plurality (four) of end faces 30a1, and these plurality of end faces 30a1 are substantially at the same position in the Z direction, that is, substantially flush. The protrusion 30a2 protrudes in the opposite direction of the Z direction from each of the end faces 30a1. The protrusion 30a2 extends along the peripheral wall of the columnar member 30A at a substantially constant height in the opposite direction of the Z direction from the end face 30a1.

[0014] The pressing member 20A (20) is a quadrangular and plate-shaped member, having a substantially constant thickness in the Z direction, intersecting with and extending substantially orthogonally to the Z direction. An opening 20a penetrating the pressing member 20A in the Z direction is provided at a substantially central portion of the pressing member 20A. The opening 20a is a hole through which the columnar member 30A penetrates. The opening 20a has a shape substantially along the outer peripheral surface 30b of the columnar member 30A. Specifically, when viewed in the Z direction, it has a quadrangular shape with rounded corners. When the columnar member 30A penetrates through the opening 20a, a gap is formed over the entire circumference between the inner surface of the opening 20a and the outer peripheral surface 30b. Note that the shape of the opening 20a only needs to allow the columnar member 30A to penetrate with a gap, and it does not necessarily need to follow the shape of the outer peripheral surface 30b over the entire circumference. In other words, the gaps do not have to be at the same interval over the entire circumference. Further, a plurality of openings 20b penetrating the pressing member 20A in the Z direction are provided in the pressing member 20A separately from the opening 20a. The opening 20b is a hole through which the anchor bolt 41 penetrates. The opening 20a is an example of a second opening.

[0015] The bottom plate 10A (10) is a quadrangular and plate-shaped member, having a substantially constant thickness in the Z direction, intersecting with and extending substantially orthogonally to the Z direction. The bottom plate 10A is placed on the installation surface P (see FIGS. 1 and 2). The bottom plate 10A has a surface 10a facing in the Z direction on the side opposite to the installation surface P. The surface 10a intersects with and extends substantially orthogonally to the Z direction. A plurality of openings 10b penetrating the bottom plate 10A in the Z direction are provided in the bottom plate 10A. The opening 10b is a hole through which the anchor bolt 41 penetrates.

[0016] In addition to the opening 10b, the bottom plate 10 is provided with a plurality of openings 10c that penetrate the bottom plate 10A in the Z direction. The opening 10c is a hole into which the protrusion 30a2 of the columnar member 30A is inserted. In a state where the protrusion 30a2 is inserted into the opening 10c, the surface 10a and the end face 30a1 of the columnar member 30A are in contact with each other at the peripheral portion of the opening 10c. The columnar member 30 and the bottom plate 10 are configured such that the columnar member 30 extends in the Z direction with the end face 30a1 and the surface 10a in contact with each other. Specifically, the end faces 30a1 and the surface 10a at a plurality of locations and the extending direction (Z direction) of the central axis Ax of the columnar member 30 are configured to be substantially orthogonal to each other. With such a configuration, the columnar member 30 extends on the bottom plate 10 in a state where the end face 30a1 and the surface 10a are abutted against each other. The surface 10a can also be referred to as the abutting surface of the end face 30a1.

[0017] The intervening member 50A (50) is a quadrangular and plate-shaped member, having a substantially constant thickness in the Z direction, intersecting with and extending substantially orthogonally to the Z direction. The intervening member 50A is located between the bottom plate 10A and the pressing member 20A, and in an assembled state where the nut 42 is tightened, it is sandwiched between the bottom plate 10A and the pressing member 20A in the Z direction. The intervening member 50A is provided with a plurality of openings 50a that penetrate the intervening member 50A in the Z direction. The opening 50a is a notch through which the anchor bolt 41 of the coupling mechanism 40 passes. Here, although the anchor bolt 41 passes through the opening 10b of the bottom plate 10A and the opening 20b of the pressing member 20A, in a pre-assembled state where the nut 42 has not been tightened yet, in order to enable the intervening member 50A to be inserted and removed in a direction intersecting with the Z direction (in this example, the X direction), the opening 50a is preferably a notch extending in the direction intersecting with the Z direction. Further, when a plurality of openings 50a are provided in one intervening member 50A as in the present embodiment, the plurality of openings 50a are preferably notches that are opened in the same direction and are substantially parallel to each other. In the present embodiment, the support structure 100A includes two intervening members 50A, but the number of intervening members 50 may be 1 or 3 or more.

[0018] [Engagement Structure between Columnar Member and Pressing Member] Figure 4 is an exploded perspective view of the columnar member 30A and the pressing member 20A in a state before the columnar member 30A is inserted into the opening 20a of the pressing member 20A. As described above, the columnar member 30A has a substantially rectangular tubular shape. That is, the outer peripheral surface 30b has four flat portions 30b1 and four corner portions 30b2. The flat portion 30b1 is an example of the first part, and the corner portion 30b2, which is farther from the central axis Ax than the flat portion 30b1, is an example of the second part.

[0019] Also, as described above, the inner surface of the opening 20a is configured to face the outer peripheral surface 30b with a gap in a state where the columnar member 30A penetrates the opening 20a of the pressing member 20A (hereinafter referred to as the penetrating state). That is, the peripheral edge portion 20c of the opening 20a has a straight portion 20c1 whose edge extends linearly facing the flat portion 30b1 in the penetrating state, and a corner portion 20c2 facing the corner portion 30b2 in the penetrating state. The corner portion 20c2 is a portion where the edge of the peripheral edge portion 20c is recessed in a substantially V shape in a direction away from the central axis Ax in a plan view seen from the opposite direction of the Z direction.

[0020] Furthermore, as shown in FIG. 4, side openings 30c are provided at the four corner portions 30b2 of the columnar member 30A, respectively. The side openings 30c are open outward in the radial direction with respect to the central axis Ax. The four side openings 30c are substantially the same in position in the Z direction and each have a side surface 30c1 facing the Z direction. The positions of the four side surfaces 30c1 in the Z direction are substantially the same. Also, the width of the side opening 30c in the Z direction is set to be larger than the thickness of the pressing member 20A, respectively.

[0021] From the state of FIG. 4, by moving the columnar member 30A in the direction opposite to the Z direction with respect to the pressing member 20A, a penetrating state is achieved. Further, by moving the columnar member 30A in the direction opposite to the Z direction, the state shown in FIGS. 5 and 6 is obtained, where the side opening 30c and the pressing member 20A are arranged in a direction intersecting the Z direction. FIG. 5 is a perspective view of the state. FIG. 6 is a cross-sectional view intersecting the Z direction in the state, and is a cross-sectional view at a position slightly shifted in the Z direction from the pressing member 20A. In FIG. 6, only the reference numerals related to the corner portions 30b2 located at the ends in the opposite directions of the X direction and the Y direction are given. Also, the position of the pressing member 20A in the states of FIGS. 5 and 6 is denoted as P1.

[0022] In the states of FIGS. 5 and 6, the side opening 30c faces the corner portion 20c2 of the peripheral edge portion 20c, and the flat portion 30b1 faces the straight portion 20c1 of the peripheral edge portion 20c with a gap therebetween. The straight portion 20c1 is an example of the third part, and the corner portion 20c2 is an example of the fourth part.

[0023] From the states of FIGS. 5 and 6, when the pressing member 20A is rotated 45° clockwise or counterclockwise in plan view about the central axis Ax, an engaged state in which the pressing member 20A and the columnar member 30A are engaged, as shown in FIGS. 7 and 8, is obtained. FIG. 7 is a perspective view of the engaged state. FIG. 8 is a cross-sectional view intersecting the Z direction in the engaged state, and is a cross-sectional view at a position slightly shifted in the Z direction from the pressing member 20A. In FIG. 8, only the reference numerals related to the corner portions 30b2 located at the ends in the opposite directions of the X direction and the Y direction are given. The position of the pressing member 20A in the states of FIGS. 7 and 8 is denoted as P2.

[0024] In the engaged state of FIGS. 7 and 8, that is, when the pressing member 20A is located at position P2, the straight portion 20c1 of the pressing member 20A is inserted into the side opening 30c of the columnar member 30A, and the flat portion 30b1 of the columnar member 30A faces the corner portion 20c2 of the pressing member 20A.

[0025] In the present embodiment, the distance from the geometric center (central axis Ax) of the opening 20a of the pressing member 20A in plan view to the edge of the straight portion 20c1 is shorter than the distance from the central axis Ax to the corner portion 30b2 of the columnar member 30A. For this reason, in the above-described penetrating state, when the side surface opening 30c and the pressing member 20A are not arranged side by side in the direction intersecting the Z direction, even if an attempt is made to rotate the pressing member 20A around the central axis Ax, the straight portion 20c1 and the corner portion 30b2 interfere with each other and cannot be rotated. On the other hand, as shown in FIGS. 5 to 8, at a position where the side surface opening 30c and the pressing member 20A are arranged side by side in the direction intersecting the Z direction, when the pressing member 20A is rotated around the central axis Ax, the straight portion 20c1 can enter the side surface opening 30c provided so as to notch the corner portion 30b2. That is, at a position where the side surface opening 30c and the pressing member 20A are arranged side by side in the direction intersecting the Z direction, the columnar member 30A and the pressing member 20A can change from the pre-engagement state of FIGS. 5 and 6 to the engagement state of FIGS. 7 and 8. In other words, the pressing member 20A can rotate around the central axis Ax and move from the position P1 to the position P2.

[0026] Thus, in this embodiment, an opening 20a is formed in the pressing member 20A so as to face the outer peripheral surface 30b of the rectangular tubular columnar member 30A with a gap by penetrating the columnar member 30A. And a side opening 30c into which the pressing member 20A rotated around the central axis Ax can be partially inserted is formed at the corner 30b2 of the columnar member 30A. In this configuration, as shown in FIG. 4, after the columnar member 30A is inserted into the opening 20a, at a position where the side opening 30c and the pressing member 20A are aligned in the Z direction (the state before engagement in FIGS. 5 and 6), by rotating the pressing member 20A around the central axis Ax, the straight portion 20c1 of the peripheral edge portion 20c of the opening 20a can be inserted into the side opening 30c. Thereby, the straight portion 20c1, that is, the pressing member 20A is partially inserted into the side opening 30c, and an engaged state in which the columnar member 30A and the pressing member 20A are engaged in the Z direction is obtained. Further, in the engaged state, the side surface 30c1 of the side opening 30c and the back surface 20d on the opposite side of the pressing member 20A in the Z direction can be brought into contact with each other. In this configuration, the straight portion 20c1 is a portion that enters from a position outside the side opening 30c into the side opening 30c along with the rotational movement of the pressing member 20A around the central axis Ax with respect to the columnar member 30A in a state where the coupling mechanism 40 is not attached, that is, a portion inserted into the side opening 30c, and is an example of the first insertion portion. The side opening 30c is an example of the first opening.

[0027] [Assembly of Components and Fixing by Coupling Mechanism] FIG. 9 is an exploded side view showing a state in which a sub-assembly in which a pressing member 20A and a columnar member 30A are engaged is brought close to a bottom plate 10A. As shown in FIG. 9, an end portion 30a of the columnar member 30A is brought close to the bottom plate 10A, and a protrusion 30a2 provided on the end portion 30a is inserted into an opening 10c provided in the bottom plate 10A. The opening 10c opens at least in the Z direction, that is, toward the side opposite to the installation surface P. Further, an end face 30a1 is in contact with a surface 10a of the bottom plate 10 and is supported by the bottom plate 10A. The opening 10c is an example of a third opening, the end face 30a1 is an example of a supported portion, and the protrusion 30a2 is an example of a second insertion portion. In this structure, a side surface (inner peripheral surface) of the opening 10c restricts movement of the protrusion 30a2, and thus the columnar member 30A, in a direction intersecting the Z direction of the protrusion 30a2 in a state where the protrusion 20a2 is inserted. With such a configuration, for example, the columnar member 30A can be positioned with respect to the bottom plate 10A, and displacement of the columnar member 30A with respect to the bottom plate 10A in a direction intersecting the Z direction can be suppressed.

[0028] FIG. 10 is a side view of the support structure 100A before tightening the nut 42. For clarity, in FIG. 10, the intervening member 50A is shown by a two-dot chain line. The coupling mechanism 40 has an anchor bolt 41, a nut 42, and a pin 43. The lower part of the anchor bolt 41 is inserted into a lower hole provided below the installation surface P, and is embedded and fixed below the installation surface P by expanding the diameter of the biting portion 41a by driving the pin 43. The male screw portion 41b of the anchor bolt 41 meshes with the female screw portion 42b of the nut 42. When the nut 42 is tightened, with the meshing, that is, the coupling, of the male screw portion 41b and the female screw portion 42b, the nut 42 moves in the direction opposite to the Z direction, that is, in the direction approaching the installation surface P. As a result, the nut 42 presses the pressing member 20A in the direction opposite to the Z direction, either directly or via a washer or the like. Further, as described above, the pressing member 20A and the columnar member 30A are engaged in the Z direction, and the back surface 20d of the pressing member 20A faces the side surface 30c1 of the side surface opening 30c. Therefore, the pressing member 20A pressed in the direction approaching the installation surface P by the nut 42 presses the columnar member 30A in the direction approaching the installation surface P via the contact portion between the back surface 20d and the side surface 30c1. As a result, the columnar member 30A is pressed together with the bottom plate 10A onto the installation surface P. Thus, according to the present embodiment, with a relatively simple configuration in which the pressing member 20 and the columnar member 30A are engaged and the pressing member 20 is pressed in the direction approaching the installation surface P by the coupling mechanism 40, a support structure 100 in which the columnar member 30 extends in the Z direction and is fixed on the installation surface P is obtained. In this configuration, the male screw portion 41b is an example of a coupled portion, and the female screw portion 42b is an example of a coupling portion. Further, the side surface 30c1 is an example of a pressed portion and a pressed region, and the back surface 20d (the region facing the side surface 30c1) is an example of a first pressing portion and a pressing region.

[0029] Also, in this configuration, as the nut 42 is tightened, the portion of the pressing member 20A that is pressed by the nut 42 moves in the direction opposite to the Z direction, while the portion of the pressing member 20A that faces the side surface 30c1 is supported by the side surface 30c1 and thus does not move in the direction opposite to the Z direction. Therefore, the pressing member 20 bends in a state where the peripheral portion moves in the direction opposite to the Z direction and the central portion bulges in the Z direction. Along with such bending of the pressing member 20A, in the vicinity of the nut 42, the gap g between the surface 10a of the bottom plate 10A and the back surface 20d of the pressing member 20A becomes narrower than before tightening. Here, if there is no intervening member 50 between the bottom plate 10 and the pressing member 20, since the size of the gap g is relatively large, there is a risk that the pressing member 20A will bend excessively and eventually undergo plastic deformation as the nut 42 is tightened. If the pressing member 20A undergoes plastic deformation, there is a risk that sufficient pressing force to press the columnar member 30A in the direction opposite to the Z direction against the bottom plate 10A cannot be obtained. In this regard, according to the present embodiment, by interposing the intervening member 50A(50) having a thickness t thinner than the gap g, the maximum bending amount (g - t) of the pressing member 20 can be made relatively small, and excessive bending of the pressing member 20 can be suppressed. At this time, in order to obtain an appropriate maximum bending amount (g - t), a plurality of types of intervening members 50 having different thicknesses may be prepared and an intervening member 50 having an appropriate thickness may be selected and interposed as appropriate. In order to facilitate the replacement of the intervening member 50 in this case, as shown in FIG. 10, the intervening member 50 may be configured to be insertable and removable in a direction intersecting the Z direction in a state where the anchor bolt 41 passes through the bottom plate 10A and the pressing member 20A. The surface 10a is an example of the first surface, and the back surface 20d is an example of the second surface. The intervening member 50A(50) is an example of the third member. Also, the intervening member 50 may also be referred to as a shim.

[0030] As described above, in the present embodiment, as the male screw portion 41b (the portion to be joined) of the anchor bolt 41 and the female screw portion 42b (the joining portion) of the nut 42 are joined, the nut 42 (the second pressing portion) presses the pressing member 20 (the second member) in a direction approaching the installation surface P, and the back surface 20d (the first pressing portion) of the pressing member 20 presses the side surface 30c1 (the portion to be pressed) of the columnar member 30 in a direction approaching the installation surface P. As a result, the columnar member 30 is pressed against the bottom plate 10, and the columnar member 30 extends in a direction intersecting the installation surface P in a posture pressed against the bottom plate 10. According to this configuration, the column support structure 100 having a relatively simple configuration that does not require a welding portion can be installed by a construction procedure that does not require a welding process. That is, according to the present embodiment, a new and improved column support structure 100 that does not require a welding process and can avoid the problems caused by the welding process can be obtained.

[0031] Further, in the present embodiment, the columnar member 30 and the pressing member 20 are configured to be engageable by the straight portion 20c1 (the first insertion portion) entering the side opening 30c (the first opening). According to this configuration, a configuration in which the pressing member 20 pressed by the nut 42 can press the columnar member 30 can be obtained by a relatively simple configuration and a relatively simple process.

[0032] In addition, in the present embodiment, the outer peripheral surface 30b of the columnar member 30 has a flat surface portion 30b1 (first portion) and a corner portion 30b2 (second portion) whose distance from the central axis Ax is longer than that of the flat surface portion 30b1, and the side surface opening 30c is provided at the corner portion 30b2. On the other hand, the pressing member 20 is provided with an opening 20a (second opening) through which the columnar member 30 penetrates, and at the peripheral edge of the opening 20a, there are provided a straight portion 20c1 (third portion) facing the flat surface portion 30b1 with a gap in the penetrating state of the columnar member 30 and a corner portion 20c2 (fourth portion) facing the corner portion 30b2 with a gap. In this configuration, the straight portion 20c1 as the first insertion portion can enter into the side surface opening 30c from a position facing the flat surface portion 30b1 outside the side surface opening 30c as the pressing member 20 rotates around the central axis Ax with respect to the columnar member 30. It can be said that this configuration utilizes the fact that the distance from the central axis Ax of the corner portion 30c2 of the outer peripheral surface 30b of the columnar member 30 having a polygonal cross section is longer than the distance from the central axis Ax of the flat surface portion 30b1. That is, by providing the side surface opening 30c at the polygonal corner portion 30c2, the straight portion 20c1 enters the side surface opening 30c as the pressing member 20 rotates around the central axis Ax, and the straight portion 20c1 and the side surface 30c1 of the side surface opening 30c can be engaged in the Z direction. That is, with a relatively simple configuration of providing the side surface opening 30c at the corner portion 30c2, an engagement structure can be obtained in which the pressing member 20 pressed by the nut 42 can press the columnar member 30.

[0033] In addition, in the present embodiment, the side surfaces 30c1 (pressed regions) of a plurality of side surface openings 30c separated from each other are provided on the columnar member 30, and portions (pressing regions) facing each of the side surface openings 30c are provided on the back surface 20d of the pressing member 20. According to this configuration, for example, the deviation of the pressing force can be reduced compared to the case where the pressing member 20 presses the columnar member 30 at one location, and the posture of the columnar member 30 can be further stabilized.

[0034] In addition, in the present embodiment, a component or a part having rotational symmetry of n times (n: an integer of 2 or more) is provided. For example, the columnar member 30A (near the end in the opposite direction of the Z direction), the pressing member 20A, and the bottom plate 10 all have a shape that is rotationally symmetric four times around the central axis Ax. In this case, since the same shape is obtained every 90° rotation around the central axis Ax, the assembly of the components can be performed more easily and quickly. Further, the pressing member 20A and the bottom plate 10A have a shape that is symmetric with respect to a virtual reference plane intersecting the Z direction. As a result, since the same shape is obtained even when the front and back are interchanged, the assembly of the components can be performed even more easily and quickly. Further, the two intervening members 50A included in the support structure 100A are shared as components having the same structure. Thereby, the types of components can be reduced, and thus the labor and cost required for manufacturing can be reduced.

[0035] [Second Embodiment] FIG. 11 is a perspective view of the support structure 100B (100) of the second embodiment. The support structure 100B has the same configuration as the support structure 100A of the first embodiment described above. However, it is different from the first embodiment in that the intervening member 50 is absent and the number of coupling mechanisms 40 is 2.

[0036] FIG. 12 is a perspective view of a sub-assembly in which the columnar member 30B (30) and the pressing member 20B (20) are engaged and integrated. The structure for engaging the columnar member 30B and the pressing member 20B in the present embodiment is the same as that in the first embodiment described above. That is, also in the present embodiment, the columnar member 30B is inserted into the opening 20a of the pressing member 20B, and the pressing member 20B is rotated around the central axis Ax in a state where the side opening 30c of the columnar member 30B faces the peripheral edge of the opening 20a of the pressing member 20B, whereby a part of the peripheral edge is inserted into the side opening 30c, and thereby the columnar member 30B and the pressing member 20B are engaged in the Z direction. That is, similar to the first embodiment, in each side opening 30c, the back surface 20d of the pressing member 20B faces the side surface 30c1 of the side opening 30c, and a pressing force in the direction opposite to the Z direction is applied from the pressing member 20B to the columnar member 30B.

[0037] In this state, as shown in FIG. 12, the end portion 30a of the columnar member 30 protrudes in the direction opposite to the Z direction from the back surface 20d of the pressing member 20B. Similar to the first embodiment, the end portion 30a is provided with an end surface 30a1 and a protrusion 30a2 protruding in the direction opposite to the Z direction from the end surface 30a1.

[0038] FIG. 13 is an exploded perspective view of the columnar member 30B(30) and the bottom plate 10B(10). The bottom plate 10B is provided with an opening 10c into which the protrusion 30a2 is inserted. As shown in FIGS. 12 and 13, in this embodiment, the protrusion 30a2 is provided at the end portion in the direction opposite to the Z direction of the corner portion 30b2 of the outer peripheral surface 30b (hereinafter simply referred to as the tip), and the end surface 30a1 is provided at the tip of the flat surface portion 30b1. That is, the opening 10c has a triangular cross-sectional shape in accordance with the shape of the protrusion 30a2 provided at the tip of the corner portion 30b2. However, the shape of the opening 10c only needs to be a shape into which the protrusion 30a2 can be inserted and a shape in which the surface 10a and the end surface 30a1 can come into contact with each other at the peripheral edge portion, and is not limited to the shape in FIG. 13.

[0039] The side opening 30c is provided at the corner portion 30b2. In this embodiment, the side opening 30c and the side surface 30c1 are aligned with the protrusion 30a2 in the Z direction and are not aligned with the end surface 30a1 in the Z direction.

[0040] FIG. 14 is a side view of the sub-assembly in which the columnar member 30B(30) and the pressing member 20B(20) are engaged and integrated, showing the state in which the sub-assembly is combined with the bottom plate 10B(10). However, for clarity, in FIG. 14, the bottom plate 10B is shown by a two-dot chain line.

[0041] Regarding the columnar member 30, in order to ensure the positional accuracy in the Z direction when processing the side opening 30c and the required strength of the columnar member 30 against the pressing force received by the side surface 30c1 from the pressing member 20, for the portion from the side surface 30c1 to the end portion in the opposite direction of the Z direction, a required length in the Z direction is necessary. For this reason, although not shown, if the side surface 30c1 and the end surface 30a1 were aligned in the Z direction, the required length would be necessary between the side surface 30c1 and the end surface 30a1. Along with this, the gap between the back surface 20d of the pressing member 20B in contact with the side surface 30c1 and the front surface 10a of the bottom plate 10B in contact with the end surface 30a1 would have to be made somewhat larger. In this regard, in the present embodiment, as described above, since the end surface 30a1 and the side surface 30c1 are not aligned in the Z direction, the positions of the end surface 30a1 and the side surface 30c1 in the Z direction can be brought closer. Along with this, the gap g between the back surface 20d of the pressing member 20B and the front surface 10a of the bottom plate 10B can be made smaller. As a result, it becomes possible to omit the intervening member 50 that fills the gap g. However, even in such a configuration, by appropriately setting the relative positional relationship between the end surface 30a1 and the side surface 30c1 in the Z direction, the gap g can be ensured to be wider, and the intervening member 50 can be inserted between the bottom plate 10B and the pressing member 20B. In this case, similar to the first embodiment, a plurality of types of intervening members 50 having different thicknesses may be prepared, and an intervening member 50 having an appropriate thickness may be selected and interposed.

[0042] Even in the present embodiment described above, the same effects based on the same configuration as in the first embodiment can be obtained. Also, in the present embodiment, the end surface 30a1 (the supported portion) and the side surface 30c1 (the pressed portion) are not aligned in the Z direction (the extending direction of the columnar member 30). Therefore, according to the present embodiment, the intervening member 50 can be omitted, and thus the number of parts can be reduced, and the labor and cost required for manufacturing can be reduced.

[0043] [Third Embodiment] FIG. 15 is a perspective view of the column structure 100C (100) of the third embodiment. The column structure 100C has the same configuration as the column structure 100B of the second embodiment. However, it is different from the second embodiment in that the columnar member 30C (30) is a solid member having a regular hexagonal cross-section.

[0044] FIG. 16 is an exploded perspective view of the column structure 100C. As shown in FIG. 16, the columnar member 30C is provided with one side opening 30c. The side opening 30c is an annular groove having a substantially constant width in the Z direction and extending around the central axis Ax. The bottom surface of the annular groove is formed in a cylindrical surface shape centered on the central axis Ax. Further, in the one side opening 30c, six side surfaces 30c1 are formed at positions adjacent to the corner 30b2 of the outer peripheral surface 30b in the Z direction.

[0045] In the pressing member 20C (20), the shape of the opening 20a through which the columnar member 30C passes is a regular hexagon. The structure for engaging the columnar member 30C and the pressing member 20C is the same as that of the first and second embodiments. That is, also in this embodiment, the columnar member 30C is inserted into the opening 20a of the pressing member 20C, and the pressing member 20C is rotated around the central axis Ax in a state where the side opening 30c of the columnar member 30C faces the peripheral edge of the opening 20a of the pressing member 20C, so that a part of the peripheral edge is inserted into the side opening 30c, whereby a state in which the columnar member 30C and the pressing member 20C are engaged in the Z direction is obtained. That is, similar to the other embodiments, in the side opening 30c, the back surface 20d of the pressing member 20C faces the side surface 30c1 of the side opening 30c, and a configuration in which a pressing force in the opposite direction to the Z direction acts from the pressing member 20C to the columnar member 30C is obtained.

[0046] Further, the bottom plate 10C (10) is provided with six openings 10c into which six protrusions 30a2 provided at the end 30a of the columnar member 30C are inserted. Note that the shape of the opening 10c only needs to be a shape into which the protrusion 30a2 can be inserted and a shape in which the surface 10a and the end surface 30a1 can be in contact with each other at the peripheral edge, and is not limited to the shape shown in FIG. 16.

[0047] Also, in the present embodiment, the columnar member 30C has a shape that is symmetric about the central axis Ax six times. In this case, since the shape is the same every 60° rotation about the central axis Ax, the assembly of the components can be performed more easily and quickly.

[0048] Even in the present embodiment described above, the same effects as those based on the same configuration as in the other embodiments can be obtained.

[0049] [Fourth Embodiment] FIG. 17 is a perspective view of the support structure 100D (100) of the fourth embodiment. The support structure 100D has the same configuration as the support structure 100 of the other embodiments described above. However, the configuration in which the pressing member 20D (20) engages with the columnar member 30D (30) is different from that of the other embodiments.

[0050] FIG. 18 is an exploded perspective view of the support structure 100D. As shown in FIG. 18, in the present embodiment, the columnar member 30D (30) has a hollow cylindrical shape, in other words, a tubular shape. On the outer peripheral surface 30b of the columnar member 30D, side surface openings 30c are provided at two positions that are opposite to each other with respect to the central axis Ax. Further, on the end portion 30a, an end surface 30a1 is provided at a position that is not aligned with the side surface opening 30c in the Z direction, and a protrusion 30a2 is provided at a position that is aligned with the side surface opening 30c in the Z direction. The columnar member 30D has a shape that is symmetric about the central axis Ax twice.

[0051] The pressing member 20D is configured to engage with the columnar member 30D by linear movement in a direction (X direction in FIG. 18) intersecting the Z direction. The pressing member 20D is provided with an opening 20a as a notch opened in the X direction. On both sides in the Y direction of the opening 20a, side edge portions 20c3 extending in the X direction are provided. As shown in FIG. 18, the side edge portion 20c3 can enter from a position outside the side surface opening 30c into the side surface opening 30c as the pressing member 20D linearly moves in the X direction with respect to the columnar member 30D. Thereby, the pressing member 20D and the columnar member 30D are engaged in the Z direction. That is, similar to the other embodiments, in each side surface opening 30c, the back surface 20d of the pressing member 20D faces the side surface 30c1 of the side surface opening 30c, and a pressing force in the opposite direction to the Z direction is applied from the pressing member 20D to the columnar member 30D. The side edge portion 20c3 is an example of the first insertion portion.

[0052] The bottom plate 10D (10) is provided with two openings 10c into which two protrusions 30a2 provided at the end portion 30a of the columnar member 30D are inserted. In the present embodiment, after inserting the protrusion 30a2 into the opening 10c and standing the columnar member 30D on the bottom plate 10D, the pressing member 20D can be engaged with the columnar member 30D. That is, in the present embodiment, the degree of freedom of the assembly procedure is increased. Note that the shape of the opening 10c only needs to be a shape into which the protrusion 30a2 can be inserted and a shape in which the surface 10a and the end surface 30a1 can be in contact with each other at the peripheral portion thereof, and is not limited to the shape of FIG. 18.

[0053] Also, the support structure 100D is integrated by three coupling mechanisms 40 (not shown in FIGS. 17 and 18, see FIG. 16 etc.), but the number of the coupling mechanisms 40 is not limited to 3, and may be 2 or 4 or more.

[0054] Even in the above-described embodiment, the same effects as those of the above-described other embodiments can be obtained based on the same configuration. Further, according to the present embodiment, the side edge portion 20c3 (first insertion portion) can enter the side surface opening 30c from a position outside the side surface opening 30c as the columnar member 30D of the pressing member 20D linearly moves in the X direction (intersecting direction). According to the present embodiment, a configuration in which the pressing member 20 can press the columnar member 30 can be obtained by a simpler configuration and a simpler process.

[0055] [Fifth Embodiment] FIG. 19 is a perspective view of a column support structure 100E (100) according to the fifth embodiment. The column support structure 100E has the same configuration as the column support structure 100 of the above-described other embodiments. However, it is different from the above-described other embodiments in that it includes a plurality of pressing members 20E (20) and a plurality of bottom plates 10E (10).

[0056] FIG. 20 is an exploded perspective view of a part of the column support structure 100E. In FIG. 20, only one of the two pressing members 20E and the bottom plate 10E included in the column support structure 100E of FIG. 19 is shown. In the following description, only one pressing member 20E and the bottom plate 10E shown in FIG. 20 will be described. Since the other pressing member 20E and the bottom plate 10E and the structures related thereto are the same as those shown in FIG. 20, the description thereof will be omitted.

[0057] As shown in FIG. 20, in the present embodiment, the columnar member 30E has a rectangular tubular shape. A side surface opening 30c is provided in a flat surface portion 30b1 of an outer peripheral surface 30b of the columnar member 30E. The side surface opening 30c is provided at a substantially central portion in the width direction (X direction in FIG. 20) of each flat surface portion 30b1. Further, an end surface 30a1 is provided at an end portion 30a at a position not aligned with the side surface opening 30c in the Z direction, that is, at a position adjacent to a corner portion 30b2 of the outer peripheral surface 30b, and a protrusion 30a2 is provided at a position aligned with the side surface opening 30c in the Z direction. The columnar member 30E has a shape that is rotationally symmetric four times around the central axis Ax.

[0058] Also in this embodiment, the pressing member 20E is configured to engage with the columnar member 30E by linear movement in a direction intersecting the Z direction (the opposite direction of the Y direction in FIG. 20). The pressing member 20E has an end face 20a1 and a protrusion 20c4. The end face 20a1 faces the flat surface portion 30b1 of the columnar member 30E. The protrusion 20c4 protrudes from substantially the center of the end face 20a1 in the width direction (the X direction in FIG. 20). As shown in FIG. 20, the protrusion 20c4 can enter from a position outside the side surface opening 30c into the side surface opening 30c as the pressing member 20E linearly moves in the opposite direction of the Y direction with respect to the columnar member 30E. Thereby, the pressing member 20E and the columnar member 30E engage in the Z direction. That is, similar to the above-described other embodiments, in each side surface opening 30c, the back surface 20d of the pressing member 20E faces the side surface 30c1 of the side surface opening 30c, and a pressing force in the opposite direction of the Z direction acts from the pressing member 20E on the columnar member 30E. The protrusion 20c4 is an example of the first insertion portion.

[0059] The bottom plate 10E (10) is provided with an opening 10c into which a protrusion 30a2 provided at the end 30a of the columnar member 30E is inserted. In this embodiment, the opening 10c is a notch. Also in this embodiment, similar to the fourth embodiment, after inserting the protrusion 30a2 into the opening 10c and standing the columnar member 30E on the bottom plate 10E, the pressing member 20E can be engaged with the columnar member 30E. That is, in this embodiment, the degree of freedom of the assembly procedure is increased.

[0060] Also, as shown in FIG. 19, the support structure 100E has the same configuration as that in FIG. 20 on the side opposite to the columnar member 30E. When the configuration in FIG. 19 is viewed in the opposite direction of the Z direction, a set of the pressing member 20E and the bottom plate 10E is arranged in an I shape with respect to the support structure 100E. However, the configuration similar to that in FIG. 20 may be further provided corresponding to another side opening 30c. That is, the support structure 100E may include three sets of the pressing member 20E and the bottom plate 10E. When the configuration is viewed in the opposite direction of the Z direction, a set of the pressing member 20E and the bottom plate 10E is arranged in a T shape with respect to the support structure 100E. Further, the support structure 100E may include four sets of the pressing member 20E and the bottom plate 10E. When the configuration is viewed in the opposite direction of the Z direction, a set of the pressing member 20E and the bottom plate 10E is arranged in a cross shape with respect to the support structure 100E. Also, when the support structure 100E having two sets of the pressing member 20E and the bottom plate 10E is viewed in the opposite direction of the Z direction, the two sets may be arranged in an L shape. As described above, according to the present embodiment, there is an advantage that the degree of freedom in the number and arrangement of the pressing member 20E and the bottom plate 10E is high. The plurality of pressing members 20E and bottom plates 10E included in the support structure 100E are each shared as parts having the same structure. Thereby, the types of parts can be reduced, and thus the labor and cost required for manufacturing can be reduced.

[0061] Also in the present embodiment described above, the same effects as those based on the same configuration as in the above-described other embodiments can be obtained. Further, according to the present embodiment, a plurality of pressing members 20E (members) each having a back surface 20d (first pressing portion) that presses a side surface 30c1 (pressed portion) are provided. According to the present embodiment, the support structure 100 can be realized with a simpler configuration. Also, the degree of freedom in the number and layout of the pressing member 20E and the bottom plate 10E can be increased, and thus there is an advantage that it becomes easier to cope with various on-site situations.

[0062] The above are examples of embodiments of the present invention. However, the above embodiments are merely examples and are not intended to limit the scope of the invention. The above embodiments can be implemented in various other forms, and various omissions, replacements, combinations, and changes can be made without departing from the gist of the invention. Also, the specifications of each component, shape, etc. (structure, type, direction, model, size, length, width, thickness, height, number, arrangement, position, material, etc.) can be appropriately changed and implemented.

[0063] For example, the joined part may be provided on the first member, rather than on an embedded member such as an anchor bolt. In that case, the first member and the installation surface may be fixed by a structure different from the coupling mechanism.
