Since a plurality of support legs are provided on the lower surface of the structure, the height and inclination of the structure can be adjusted on the installation surface by adjusting the protruding length of each support leg.

Registered Utility Model No. 3001757

However, in the past, the structure is installed on the installation surface with the support legs provided on the lower surface of the structure. Therefore, after the structure is installed on the installation surface, the protruding length of each support leg is adjusted. Need to be and cumbersome. In particular, when the weight of the structure is heavy, it may be difficult to adjust the length of each support leg.
Also, when removing the structure from the installation surface for repair or inspection, the support legs are separated from the installation surface together with the structure. Therefore, when installing the structure on the installation surface again, each support leg It is necessary to adjust the length again, which is troublesome.

  The present invention has been made in view of the above-described circumstances, and an object thereof is to provide a support leg that can easily adjust the height and inclination of a structure installed on an installation surface.

A support leg according to an aspect of the present invention is a support leg that supports the structure in order to install the structure with a space on the installation surface, and the screw rod and the screw rod are inserted in the state described above. A support surface is provided at an interval in the axial direction of the screw rod, and supports the installation surface and the lower surface of the structure by respectively contacting the installation surface and the lower surface of the structure facing each other. A pair of support portions, a position adjusting female screw portion that is screwed to the screw rod and moves at least one of the support portions in the axial direction, and a first of the pair of support portions through which the screw rod is inserted. A pair of holding members that sandwich the support portion from the axial direction; and a pair of holding female screw portions that are screwed to the screw rod and hold the first support portion and the pair of holding members immovably with respect to each other. The first support portion and the pair of the A spherical spherical convex surface is formed on one of the portions of the holding member facing each other, and a spherical concave surface that is in surface contact with the spherical convex surface is formed on the other of the portions, and the first support portion and the pair of narrow narrow surfaces are formed. In a state where the holding member is not fixed to each other by the pair of holding female screw portions, the spherical convex surface and the spherical concave surface slide with each other, whereby the axial direction of the screw rod and the support of the first support portion The inclination angle with the surface changes.

  In the support leg having the above configuration, the tilt angle between the support surfaces of the pair of support portions can be adjusted by changing the tilt angle between the axial direction of the screw rod and the support surface of the first support portion. Moreover, the space | interval of the support surfaces of a pair of support part can be adjusted by moving a support part to the axial direction of a screw rod by the internal thread part for position adjustment.

  According to the support legs having the above-described configuration, since the support legs include the pair of support parts that respectively support the installation surface and the lower surface of the structure, the distance between the support surfaces of the pair of support parts in a state where the support legs are arranged on the installation surface. And after adjusting the inclination-angle of the support surfaces of a pair of support part, it becomes possible to arrange | position a structure on the support surface of an upper support part. That is, the height and inclination of the structure installed on the installation surface can be easily adjusted.

  Further, even if the structure is removed from the installation surface for repair or inspection, the support legs can be arranged on the installation surface. Here, since the support portion is moved in the axial direction of the screw rod by the position adjusting female screw portion screwed to the screw rod, the support portion can be held at a desired position in the axial direction. Moreover, the inclination angle of the support surfaces of the pair of support portions can be held at a desired angle by fixing the first support portion and the pair of holding members by the pair of holding female screw portions. Therefore, it becomes possible to install the structure on the installation surface again without adjusting the height and inclination of the structure again.

  And in the said support leg, the said spherical convex surface may be formed in the said pinching member, and the said spherical concave surface may be formed in the said 1st support part.

  According to the above configuration, compared to the case where the spherical convex surface is formed on the first support portion and the spherical concave surface is formed on the pair of holding members, the inclination of the axial direction of the screw rod and the support surface of the first support portion is increased. The angle can be changed more greatly. Therefore, for example, it is possible to install the structure in a horizontal state on an installation surface that is more greatly inclined with respect to the horizontal plane.

  Further, in the support leg, the holding female screw portion is screwed to the screw rod, and the pair of the holding members are sandwiched from the axial direction, whereby the first support portion and the pair of holding members are A female screw portion of a pair of holding nuts that are held immovable with each other, and the female screw portion of each holding nut may also serve as the female screw portion for position adjustment that moves the first support portion in the axial direction. Good.

According to the said structure, compared with the case where a pinching member consists of a nut which formed the internal thread part for holding | maintenance, a spherical convex surface and a spherical concave surface can be formed larger. For this reason, the inclination angle between the axial direction of the screw rod and the support surface of the first support portion can be changed more greatly. Therefore, for example, it is possible to install the structure in a horizontal state on an installation surface that is more greatly inclined with respect to the horizontal plane.
Moreover, according to the said structure, the holding | maintenance internal thread part formed in each holding | maintenance nut serves also as the internal thread part for position adjustment for 1st support parts. For this reason, it is possible to reduce the number of component parts of the support leg as compared with the case where the female screw portion for position adjustment is formed on a nut separate from the holding nut.

  Further, in the support leg, the female screw portion for position adjustment for moving the second support portion in the axial direction among the pair of support portions may be formed in the second support portion.

  According to the said structure, the number of components of a support leg can be reduced compared with the case where the internal thread part for position adjustment is formed in a nut separate from a 2nd support part.

  In the support leg, the support surface of the second support portion of the pair of support portions may support the lower surface of the structure, and the support surface of the first support portion may support the installation surface.

According to the above configuration, the second support portion can be simply configured as compared with the case where the second support portion is configured as a leg portion that supports the installation surface, and thus the support leg can be manufactured at low cost. Become.
Moreover, according to the said structure, it becomes possible to support a structure more stably. That is, the weight on the first end portion side of the screw rod provided with the first support portion and the pair of holding members tends to be heavier than the weight on the second end portion side of the screw rod provided with the second support portion. . Here, the support surface of the first support portion supports the installation surface as in the above configuration, so that the center of gravity of the support leg can be set low. Therefore, compared to the case where the first support portion is arranged on the structure side, the structure can be stably supported even if the screw rod rigidity is reduced by reducing the diameter of the screw rod. Is possible.

As illustrated in FIGS. 2 and 3, the support leg 1 includes a rod-shaped screw rod 11 and a pair of support portions 12 and 13.
The screw rod 11 is configured by forming a male screw on the outer periphery. The pair of support portions 12 and 13 are provided at intervals in the axial direction of the screw rod 11 with the screw rod 11 inserted therein. Each support part 12 and 13 has the support surface 12a and 13a which support the installation surface G and the lower surface F2b of the structure F which mutually oppose. In the present embodiment, the support surface 12a of the first support portion 12 (hereinafter also referred to as the first support surface 12a) of the pair of support portions 12 and 13 supports the lower surface F2b of the structure F. The support surface 13a of the second support portion 13 (hereinafter also referred to as the second support surface 13a) supports the installation surface G.

Further, the support leg 1 includes a pair of holding members 14, a pair of holding female screw portions 15, and position adjusting female screw portions 16 and 17.
The pair of holding members 14 insert the screw rod 11 and sandwich the first support portion 12 from the axial direction of the screw rod 11. A spherical convex surface 18 having a spherical shape is formed on one of the portions of the first support portion 12 and the pair of holding members 14 facing each other. A spherical concave surface 19 that is in surface contact with the spherical convex surface 18 is formed on the other side of the first support portion 12 and the pair of holding members 14 facing each other.
The pair of holding female screw portions 15 are screwed onto the screw rod 11 and hold the first support portion 12 and the pair of holding members 14 so as not to move relative to each other. The position adjusting female screw portions 16 and 17 are screwed into the screw rod 11 to move at least one of the pair of support portions 12 and 13 in the axial direction of the screw rod 11.

Hereinafter, the support leg 1 of the present embodiment will be described more specifically.
The first support portion 12 is formed in a plate shape. The first support portion 12 is formed with an insertion hole 21 (hereinafter referred to as the first insertion hole 21) through which the screw rod 11 is inserted (inserted) in the thickness direction. The diameter of the first insertion hole 21 is set larger than the diameter of the screw rod 11. The first support portion 12 is sandwiched between the pair of holding members 14 from the thickness direction of the first support portion 12. The surface of the first support portion 12 that faces the upper holding member 14A of the pair of holding members 14 is the first support surface 12a described above. In the first support part 12, the axial direction of the first insertion hole 21 is orthogonal to the first support surface 12a.
A spherical concave surface 19 is formed on each surface (part) of the first support portion 12 facing each holding member 14. The center of curvature of the spherical concave surface 19 is located on the axis of the first insertion hole 21 of the first support portion 12. For this reason, the spherical concave surface 19 is formed around the first insertion hole 21. The curvature radii of the two spherical concave surfaces 19 formed on the first support portion 12 are equal to each other.

Each pinching member 14 is formed in, for example, a circular plate shape in plan view. Each holding member 14 is formed smaller than the first support portion 12 so as to cover only a part of each surface of the first support portion 12 in a state where the holding member 14 is overlapped with the first support portion 12. Each holding member 14 is formed with an insertion hole 22 (hereinafter referred to as a second insertion hole 22) through which the screw rod 11 passes. The diameter dimension of the second insertion hole 22 is set larger than the diameter dimension of the screw rod 11.
A spherical convex surface 18 is formed at a portion of each holding member 14 facing the first support portion 12. The center of curvature of the spherical convex surface 18 is located on the axis of the second insertion hole 22 of each holding member 14. For this reason, the spherical convex surface 18 is formed around the second insertion hole 22 of each holding member 14. The spherical convex surface 18 is formed over the entire region from the inner peripheral edge to the outer peripheral edge of each holding member 14 in which the second insertion holes 22 are formed.

  The radius of curvature of the spherical convex surface 18 is equal to the radius of curvature of the spherical concave surface 19 of the first support portion 12 described above. For this reason, the spherical convex surface 18 and the spherical concave surface 19 can be brought into surface contact in a state where the first support portion 12 is sandwiched between the pair of holding members 14. Moreover, even if the axial direction of the 2nd penetration hole 22 of each holding member 14 and the axial direction of the 1st penetration hole 21 of the 1st support part 12 are mutually parallel like FIG. 2, it is like FIG. Even if the axial direction of the second insertion hole 22 of each holding member 14 is inclined with respect to the axial direction of the first insertion hole 21 of the first support portion 12, the spherical convex surface 18 and the spherical concave surface 19 are brought into surface contact. be able to. In the state where the axial direction of the second insertion hole 22 of the holding member 14 and the axial direction of the first insertion hole 21 of the first support part 12 are parallel to each other as shown in FIG. The axes of the first insertion hole 21 and the second insertion hole 22 of the holding member 14 coincide with each other.

In the present embodiment, the pair of holding female screw portions 15 that hold the first support portion 12 and the pair of holding members 14 so as not to move relative to each other are a pair of holding nuts 23 that are screwed to the screw rod 11. It is a female screw part. The pair of holding nuts 23 are provided at positions where the first support portion 12 and the pair of holding members 14 attached to the screw rod 11 are sandwiched from the axial direction of the screw rod 11. The pair of holding nuts 23 hold the first support portion 12 and the pair of holding members 14 so as not to move relative to each other by sandwiching the pair of holding members 14 from the axial direction of the screw rod 11.
The female thread portion of each holding nut 23 has a female screw portion for position adjustment 16 (hereinafter referred to as a female screw portion for first position adjustment 16) that moves the first support portion 12 and the pair of holding members 14 in the axial direction of the screw rod 11. Also called).

Here, the support leg 1 of the present embodiment prevents the pinching force of the pair of holding members 14 from being lowered by the pair of holding nuts 23 described above, that is, loosening that prevents the pair of holding nuts 23 from loosening. Stop means 30 is provided.
Although the structure of the locking means 30 may be arbitrary, the locking means 30 in the illustrated example includes a locking nut 31 and a spring washer 32. The locking nut 31 is screwed onto the threaded rod 11, and the lower holding nut 23 </ b> A located between the pair of support portions 12, 13 of the pair of holding nuts 23 and the second support portion 13 described later. Between. The spring washer 32 is provided between the upper holding member 14A disposed on the first support surface 12a side of the first support portion 12 and the upper holding nut 23B.

The second support portion 13 of the present embodiment is formed as a leg portion disposed on the installation surface G.
The second support portion 13 includes a main body portion 24 formed in a cylindrical shape, and a flange portion 25 provided at an end portion in the axial direction of the main body portion 24. The flange portion 25 is formed in an annular plate shape that protrudes radially outward from the outer peripheral surface of the main body portion 24. The surface of the first end in the axial direction of the second support portion 13 that forms the flange portion 25 is the second support surface 13 a of the second support portion 13. In the second support part 13, the axial direction of the main body part 24 is orthogonal to the second support surface 13a.
The flange portion 25 is formed with a plurality of fixing holes 26 penetrating in the thickness direction. The plurality of fixing holes 26 are arranged at equal intervals in the circumferential direction of the flange portion 25. The fixing hole 26 is used, for example, when fixing the second support portion 13 to the installation surface G by screwing.

In the present embodiment, the position adjusting female screw portion 17 (hereinafter referred to as the second position adjusting female screw portion 17) that moves the second supporting portion 13 in the axial direction of the screw rod 11 is the same as the second supporting portion 13. It is formed on the inner peripheral surface. That is, in the present embodiment, the second support portion 13 is screwed to the screw rod 11. As a result, the second support surface 13 a of the second support portion 13 is held in a state orthogonal to the axial direction of the screw rod 11.
Furthermore, the support leg 1 of the present embodiment includes a misalignment prevention means 40 that prevents the above-described second support portion 13 from misaligning in the axial direction of the screw rod 11. The misalignment prevention means 40 in the illustrated example includes a spring washer 41 and a fixing nut 42 that are sequentially arranged on the first support portion 12 side with respect to the second support portion 13, but is not limited thereto.

Next, a method for installing the structure F on the installation surface G using the support legs 1 of the present embodiment will be described.
In order to install the structure F on the installation surface G, first, the plurality of support legs 1 are arranged on the installation surface G. At this time, the second support surface 13 a of the second support portion 13 is brought into contact with the installation surface G.
Next, the spacing between the support surfaces 12 a and 13 a of the pair of support portions 12 and 13 in each support leg 1 is adjusted. Further, in each support leg 1, the inclination angle between the support surfaces 12 a and 13 a of the pair of support portions 12 and 13 is adjusted.

  When adjusting the distance between the pair of support surfaces 12 a and 13 a, for example, the holding nut 23 having the first position adjusting female screw portion 16 is rotated to move the first support portion 12 in the axial direction of the screw rod 11. Move it. Further, for example, the second support portion 13 itself having the second position adjusting female screw portion 17 may be rotated to move the second support portion 13 in the axial direction of the screw rod 11. The position adjustment of the second support portion 13 is preferably performed within a range in which the screw rod 11 does not protrude from the support surfaces 12 a and 13 a of the second support portion 13.

The adjustment of the inclination angle between the pair of support surfaces 12a and 13a is performed, for example, so that the first support surface 12a of the first support portion 12 is horizontal. When adjusting the inclination angle between the pair of support surfaces 12a and 13a, the screw rod 11 is in a state where the first support portion 12 and the pair of holding members 14 are not fixed to each other by the pair of holding nuts 23. The screw rod 11 and the first support part 12 may be moved relative to each other so that the inclination angle between the axial direction of the first support part 12 and the axial direction of the first insertion hole 21 of the first support part 12 changes. At this time, the spherical convex surface 18 and the spherical concave surface 19 slide with each other so that the axial direction of the second insertion hole 22 of the pair of holding members 14 follows the axial direction of the screw rod 11. At this time, as illustrated in FIG. 3, the pair of sandwiching members 14 has the center of curvature of each spherical convex surface 18 so that the axially parallel states of these second insertion holes 22 are maintained. Move in opposite directions as the center.
Accordingly, the inclination angle of the second insertion hole 22 of the pair of holding members 14 with respect to the axial direction of the first insertion hole 21 of the first support portion 12 changes. Thereby, the inclination angle between the axial direction of the screw rod 11 and the first support surface 12a of the first support portion 12 changes, and as a result, the first support portion 12 of the second support portion 13 with respect to the second support surface 13a. The inclination angle of the first support surface 12a can be adjusted.

  In the above description, the inclination angle between the support surfaces 12a and 13a is based on the state in which the support surfaces 12a and 13a of the pair of support portions 12 and 13 are parallel to each other (0 degree). That is, the inclination angle between the axial direction of the screw rod 11 and the axial direction of the first insertion hole 21 of the first support portion 12 is the axial direction of the screw rod 11 and the axial direction of the first insertion hole 21 of the first support portion 12. Are orthogonal (0 degree).

For example, when it is necessary to position the first support surfaces 12a of the first support portions 12 of the plurality of support legs 1 on the same plane, the adjustment of the interval between the pair of support surfaces 12a and 13a and the inclination angle is as follows. It is preferable to carry out after mounting the base plate portion F2 of the structure F or a plate material for adjustment (not shown) on the first support surfaces 12a of the first support portions 12 of the plurality of support legs 1. When using the plate material for adjustment, after adjusting the space | interval and inclination angle of a pair of support surfaces 12a and 13a, the plate material for adjustment should just be removed.
By the way, on the first support surface 12a of the first support portion 12, a part of the screw rod 11, a part of the upper holding member 14A, and an upper holding nut 23B are located. For this reason, a part of the screw rod 11, a part of the upper holding member 14A, and an upper holding nut 23B are inserted into the base plate part F2 and the adjusting plate member in the thickness direction, or A through hole F4 to be inserted is preferably formed.

  After adjusting the distance between the pair of support surfaces 12a and 13a and the inclination angle as described above, the first support portion 12 and the pair of holding members 14 may be sandwiched between the pair of holding nuts 23. In this state, since the spherical convex surface 18 of each holding member 14 is pressed against the spherical concave surface 19 of the first support portion 12, the first support portion 12 and the pair of holding members 14 are held immovably with respect to each other. Moreover, in this state, the space | interval and inclination | tilt angle of a pair of support surfaces 12a and 13a set by the above-mentioned adjustment are maintained.

Thereafter, the locking nut 31 is moved in the axial direction of the screw rod 11 so that the locking nut 31 is pressed against the lower holding nut 23B. As a result, the pair of holding nuts 23 can be prevented from being loosened, that is, the first support portion 12 and the pair of holding members 14 can be prevented from being unintentionally released by the pair of holding nuts 23. it can. Moreover, it can also prevent that the 1st support part 12 moves to the axial direction of the screw rod 11 unexpectedly.
Further, the fixing nut 42 is moved so that the fixing nut 42 is pressed against the second support portion 13. Accordingly, it is possible to prevent the second support portion 13 from being unexpectedly moved in the axial direction of the screw rod 11 by the elastic force of the spring washer 41 sandwiched between the second support portion 13 and the fixing nut 42.

Finally, by placing the structure F on the first support surfaces 12a of the plurality of first support portions 12, the installation of the structure F on the installation surface G is completed.
As described above, on the first support surface 12a of the first support portion 12 on which the structure F is placed, a part of the screw rod 11, a part of the upper holding member 14A, and the upper holding member The nut 23B is located. For this reason, for example, a part of the screw rod 11, a part of the upper holding member 14A, and the upper holding nut 23B are inserted into the structure F like the through hole F4 of the base plate part F2 described above. Alternatively, a hole to be inserted is preferably formed.
Further, after the structure F is placed on the installation surface G, for example, the structure F and the first support portion 12 of each support leg 1 may be fixed by screwing or the like.

  As described above, the support leg 1 of the present embodiment includes the pair of support portions 12 and 13 that respectively support the installation surface G and the lower surface F2b of the structure F. For this reason, in the state which has arrange | positioned the support leg 1 on the installation surface G, the space | interval of the support surfaces 12a and 13a of a pair of support parts 12 and 13, and the support surfaces 12a and 13a of a pair of support parts 12 and 13 After the inclination angle is adjusted, the structure F can be disposed on the first support surface 12a of the first support portion 12. That is, the height and inclination of the structure F installed on the installation surface G can be easily adjusted.

  Even if the structure F is removed from the installation surface G for repair or inspection, the support legs 1 can be arranged on the installation surface G. The support portions 12 and 13 are held at desired positions in the axial direction by the position adjusting female screw portions 16 and 17 screwed into the screw rod 11. Further, the first support portion 12 and the pair of holding members 14 are fixed to each other by a pair of holding female screw portions 15 (a pair of holding nuts 23), whereby the support surfaces 12a of the pair of support portions 12 and 13 are supported. , 13a can be held at a desired angle. Therefore, the structure F can be installed on the installation surface G again without adjusting the height and inclination of the structure F again.

  Furthermore, according to the support leg 1 of this embodiment, the inclination angle between the support surfaces 12a, 13a of the pair of support portions 12, 13 is held at a desired angle by the pair of holding female screw portions 15. For this reason, even if the structure F receives external force due to wind, earthquake, or the like, the structure F can be prevented from swinging with respect to the installation surface G due to the structure of the support legs 1. This effect is obtained because the structure F (for example, the direction of the antenna) is required to maintain the inclination angle between the pair of support surfaces 12a and 13a or the level of the first support surface 12a of the first support portion 12 with high accuracy. This is particularly useful when a weather radar (required to set the reference position with high accuracy) is installed.

  Further, according to the support leg 1 of the present embodiment, the spherical convex surface 18 is formed on the holding member 14 and the spherical concave surface 19 is formed on the first support portion 12. For this reason, compared with the case where the spherical convex surface 18 is formed on the first support portion 12 and the spherical concave surface 19 is formed on the pair of holding members 14, the axial direction of the screw rod 11 and the first direction of the first support portion 12 are compared. The inclination angle with respect to the support surface 12a can be changed more greatly. Therefore, it becomes possible to install the structure F in a horizontal state on the installation surface G that is more greatly inclined with respect to the horizontal plane. Hereinafter, this point will be specifically described.

For example, when the spherical convex surface 18 is formed in the center portion of the first support surface 12 a of the first support portion 12, when the spherical concave surface 19 of the sandwiching member 14 is slid with respect to the spherical convex surface 18, the sandwiching member 14 is The spherical convex surface 18 may come into contact with the support surface 12a around. For this reason, the moving range of the holding member 14 with respect to the first support portion 12 is limited, and the inclination angle between the axial direction of the screw rod 11 and the first support surface 12a of the first support portion 12 cannot be changed greatly.
On the other hand, when the spherical concave surface 19 is formed in the central portion of the first support surface 12a of the first support portion 12 as in this embodiment, the spherical convex surface 18 of the holding member 14 is slid with respect to the spherical concave surface 19. Even if it is moved, the holding member 14 does not come into contact with the support surface 12 a around the spherical concave surface 19. For this reason, the movement range of the holding member 14 with respect to the first support portion 12 is not limited, and the inclination angle between the axial direction of the screw rod 11 and the first support surface 12a of the first support portion 12 can be changed more greatly. it can.

Further, in the support leg 1 of the present embodiment, the holding female screw portion 15 is a female screw portion of a pair of holding nuts 23 that sandwich the pair of holding members 14 from the axial direction of the screw rod 11. For this reason, the spherical convex surface 18 can be formed larger than the case where the pinching member 14 is a nut formed with the holding female screw portion 15.
If it demonstrates in detail, since the shape of a nut is restrict | limited by a specification, the dimension of the radial direction from the inner periphery to the outer periphery of a nut cannot fully be ensured. That is, when the pinching member 14 is formed of a nut, the spherical convex surface 18 cannot be formed large. On the other hand, when the holding female screw portion 15 is formed on the holding nut 23 separate from the holding member 14 as in the present embodiment, the holding member 14 can be set to a shape that is not restricted by the standard of the nut. For this reason, the spherical convex surface 18 can be formed larger by setting the outer diameter of the holding member 14 to be larger. Thereby, even if the inclination angle in the axial direction of the first insertion hole 21 of the first support portion 12 and the axial direction of the second insertion hole 22 of the holding member 14 is set to be larger, the spherical concave surface 19 and the spherical convex surface 18 are reduced. They can be in surface contact with each other. That is, the inclination angle between the axial direction of the screw rod 11 and the first support surface 12a of the first support portion 12 can be changed more greatly. Therefore, for example, it is possible to install the structure F in a horizontal state on the installation surface G that is more greatly inclined with respect to the horizontal plane.

Further, according to the support leg 1 of the present embodiment, the holding female screw portion 15 formed on each holding nut 23 also serves as the first position adjusting female screw portion 16 for the first support portion 12. For this reason, compared with the case where the 1st position adjustment internal thread part 16 is formed in the nut different from the holding nut 23, it becomes possible to aim at reduction of the number of components of the support leg 1. FIG.
Furthermore, in the support leg 1 of this embodiment, since the second position adjusting female thread portion 17 is formed in the second supporting portion 13, the second position adjusting female thread portion 17 is separated from the second support portion 13 by a nut. Compared with the case where it forms, it becomes possible to aim at reduction of the number of components of the support leg 1. FIG.

  Moreover, in the support leg 1 of this embodiment, the 1st support surface 12a of the 1st support part 12 supports the lower surface F2b of the structure F, and the 2nd support surface 13a of the 2nd support part 13 supports the installation surface G. To do. For this reason, the screw rod 11 inserted into the second support portion 13 does not need to protrude from the second support surface 13 a of the second support portion 13. Thereby, it becomes possible to arrange | position the support leg 1 also to the installation surface G in which it is difficult to form the hole (a through-hole or a recessed part) for inserting the screw rod 11. FIG. That is, the versatility of the support leg 1 can be improved.

In the first embodiment, the second position adjusting female screw portion 17 for adjusting the axial position of the second support portion 13 is provided on the second support portion 13. Further, a female screw portion of a pair of nuts that sandwich the second support portion 13 from the axial direction of the screw rod 11 may be used.
The second position adjusting female thread portion 17 may not be provided, for example. In this case, for example, the screw rod 11 is constituted by a bolt, and the screw portion (screw rod 11) of the bolt is inserted from the second support surface 13a side of the second support portion 13 into the cylindrical second support portion 13. In addition, the second support portion 13 may be fixed to the screw rod 11 by sandwiching the second support portion 13 between the head of the bolt and the fixing nut 42.

Furthermore, in the first embodiment, the upper holding nut 23 </ b> B may be formed integrally with the screw rod 11, for example. That is, the upper holding nut 23 </ b> B may be a head portion of a bolt constituting the screw rod 11. In this case, since the lower holding nut 23 </ b> A does not function as the first position adjusting female thread portion 16, the second position adjusting female thread portion 17 that moves the second support portion 13 in the axial direction of the screw rod 11 is provided. Necessary.
In the first embodiment, the screw rod 11 may be an anchor bolt in which the lower end of the screw rod 11 is embedded in the installation surface G, for example.

[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIGS. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

As shown in FIG. 4, the support legs 2 of the present embodiment are structured to install a structure F with a plurality (for example, three or more) of support legs 2 at intervals on the installation surface G, as in the first embodiment. The object F is supported.
For example, as shown in FIG. 4, the installation surface G of the present embodiment may be the upper surface of a plate material B provided at the top of the steel tower ST, but is not limited thereto. Further, the installation surface G may be a flat surface as in the first embodiment, but may be, for example, an uneven surface. Further, a part or the whole of the installation surface G may be, for example, a horizontal plane (see FIG. 5) or an inclined plane (see FIG. 6) that is inclined with respect to the horizontal plane.

As shown in FIGS. 5 and 6, the support leg 2 includes a rod-shaped screw rod 11 and a pair of support portions 52 and 53.
As in the first embodiment, the pair of support portions 52 and 53 are provided at intervals in the axial direction of the screw rod 11 with the screw rod 11 inserted therein. Each of the support portions 52 and 53 includes support surfaces 52a and 53a that support the installation surface G and the lower surface F2b of the structure F that face each other. However, in the present embodiment, the support surface 52a of the first support portion 52 (hereinafter also referred to as the first support surface 52a) of the pair of support portions 52 and 53 supports the installation surface G. Further, the support surface 53a of the second support portion 53 (hereinafter also referred to as the second support surface 53a) supports the lower surface F2b of the structure F.
The support leg 2 includes a pair of holding members 14, a pair of holding female screw portions 15, and position adjusting female screw portions 16 and 17, as in the first embodiment. The configuration and function of the pair of holding members 14 are the same as in the first embodiment. The functions of the pair of holding female screw portions 15 and the position adjusting female screw portions 16 and 17 are the same as those in the first embodiment.

Hereinafter, the support leg 2 of the present embodiment will be described more specifically.
The first support portion 52 of the present embodiment is formed as a leg portion disposed on the installation surface G. The first support portion 52 is formed in the same manner as the first support portion 12 of the first embodiment. That is, the first support portion 52 is formed in a plate shape. The first support portion 52 is formed with a first insertion hole 21 that penetrates (inserts) the screw rod 11 through the thickness direction thereof. The diameter of the first insertion hole 21 is set larger than the diameter of the screw rod 11. The first support portion 52 is sandwiched between the pair of holding members 14 from the thickness direction of the first support portion 52. The surface of the 1st support part 52 which opposes the lower holding member 14C among a pair of holding members 14 is the 1st support surface 52a mentioned above. In the first support portion 52, the axial direction of the first insertion hole 21 is orthogonal to the first support surface 52a.

A spherical concave surface 19 similar to that of the first embodiment is formed on each surface (part) of the first support portion 52 facing each holding member 14. The center of curvature of the spherical concave surface 19 is located on the axis of the first insertion hole 21 of the first support portion 52. For this reason, the spherical concave surface 19 is formed around the first insertion hole 21. The curvature radii of the two spherical concave surfaces 19 formed on the first support portion 52 are equal to each other.
Further, the first support portion 52 of the present embodiment is formed with a plurality of fixing holes 54 penetrating in the thickness direction. The plurality of fixing holes 54 are arranged at equal intervals in a concentric manner around the axis of the first insertion hole 21. The fixing hole 54 is used when, for example, the first support portion 52 is fixed to the installation surface G by screwing.

A spherical convex surface 18 similar to that of the first embodiment is formed at the portion of each holding member 14 facing the first support portion 52 described above. The center of curvature of the spherical convex surface 18 is located on the axis of the second insertion hole 22 of each holding member 14. For this reason, the spherical convex surface 18 is formed around the second insertion hole 22 of each holding member 14. The spherical convex surface 18 is formed over the entire region from the inner peripheral edge to the outer peripheral edge of each holding member 14 in which the second insertion holes 22 are formed.
The radius of curvature of the spherical convex surface 18 is equal to the radius of curvature of the spherical concave surface 19 of the first support portion 52 described above. For this reason, the spherical convex surface 18 and the spherical concave surface 19 can be brought into surface contact in a state where the first support portion 52 is sandwiched between the pair of holding members 14. Further, as shown in FIG. 5, even if the axial direction of the second insertion hole 22 of each holding member 14 and the axial direction of the first insertion hole 21 of the first support portion 52 are parallel to each other, as shown in FIG. Even if the axial direction of the second insertion hole 22 of each holding member 14 is inclined with respect to the axial direction of the first insertion hole 21 of the first support portion 52, the spherical convex surface 18 and the spherical concave surface 19 are brought into surface contact. be able to. In a state where the axial direction of the second insertion hole 22 of the holding member 14 and the axial direction of the first insertion hole 21 of the first support portion 52 are parallel to each other as shown in FIG. The axes of the first insertion hole 21 and the second insertion hole 22 of the holding member 14 coincide with each other.

In the present embodiment, the pair of holding female screw portions 15 that hold the first support portion 52 and the pair of holding members 14 so as not to move relative to each other are screwed to the screw rod 11 as in the first embodiment. It is an internal thread part (no code | symbol) of a pair of nuts 23 for holding. The pair of holding nuts 23 are provided at positions where the first support portion 52 and the pair of holding members 14 attached to the screw rod 11 are sandwiched from the axial direction of the screw rod 11. The pair of holding nuts 23 holds the first support portion 52 and the pair of holding members 14 so as not to move relative to each other by sandwiching the pair of holding members 14 from the axial direction of the screw rod 11.
The female screw portion of each holding nut 23 also serves as the first position adjusting female screw portion 16 that moves the first support portion 52 and the pair of holding members 14 in the axial direction of the screw rod 11.

  Here, the support leg 2 of the present embodiment prevents the pinching force of the pair of holding members 14 from being lowered by the pair of holding nuts 23 described above, that is, loosening that prevents the pair of holding nuts 23 from loosening. Stop means 70 is provided. The locking means 70 may have any configuration. The locking means 70 in the illustrated example includes a pair of locking nuts 71 that are screwed onto the screw rod 11 and are arranged so as to sandwich the pair of holding nuts 23.

The second support portion 53 includes a support nut 55 that is screwed onto the screw rod 11. Moreover, the 2nd support part 53 may be provided with the support washer 56 (flat washer) which penetrates the screw rod 11 like the example of illustration. When the second support portion 53 also includes a support washer 56 as in the illustrated example, the end surface in the axial direction of the support washer 56 forms the second support surface 53 a of the second support portion 53. For example, when the second support portion 53 includes only the support nut 55, the end surface in the axial direction of the support nut 55 forms the second support surface of the second support portion 53.
Regardless of the configuration of the second support portion 53 described above, the axial direction of the support nut 55 is orthogonal to the second support surface 53 a of the second support portion 53.

In the present embodiment, the second position adjusting female screw portion 17 that moves the second supporting portion 53 in the axial direction of the screw rod 11 is a female screw portion of the supporting nut 55. That is, the second support portion 53 (particularly the second support surface 53 a) can be moved in the axial direction of the screw rod 11 by rotating the support nut 55 screwed onto the screw rod 11.
Further, the support leg 2 in the illustrated example is screwed onto the screw rod 11 and supported by sandwiching a part of the structure F (the base plate portion F2 in the illustrated example) together with the support nut 55 of the second support portion 53. A fixing nut 57 for fixing the leg 2 to the structure F is provided. In the illustrated example, the flat washer 58 is provided between the fixing nut 57 and the structure F, but the flat washer 58 may not be provided, for example.
Further, when a part of the structure F is sandwiched between the support nut 55 and the fixing nut 57, the support leg 2 is the same as the locking means 70 described above in order to prevent the support nut 55 and the fixing nut 57 from loosening. These means may be provided.

Next, a method for installing the structure F on the installation surface G using the support legs 2 of the present embodiment will be described.
In order to install the structure F on the installation surface G, first, the plurality of support legs 2 are arranged on the installation surface G. At this time, the first support surface 52 a of the first support portion 52 is brought into contact with the installation surface G.
Here, on the first support surface 52a of the first support portion 52, a part of the screw rod 11, a part of the lower holding member 14C, a lower holding nut 23C, and a lower looseness. A retaining nut 71C is located. Therefore, the installation surface G is formed with a recess for inserting a part of the screw rod 11, a part of the lower holding member 14C, the lower holding nut 23C, and the lower locking nut 71C. There is a need to. 5 and 6, since the installation surface G of this embodiment is the upper surface of the plate material B, a part of the screw rod 11 protruding from the first support surface 52a of the first support portion 52, the lower side A through hole B1 into which a part of the holding member 14C, the lower holding nut 23C, and the lower locking nut 71C are inserted or inserted may be formed as the recess.

Subsequently, in each support leg 2, the space | interval of the support surfaces 52a and 53a of a pair of support parts 52 and 53 is adjusted. In addition, the inclination angle between the support surfaces 52a and 53a of the pair of support portions 52 and 53 in each support leg 2 is adjusted.
When adjusting the distance between the pair of support surfaces 52a, 53a, for example, the first support portion 52 can be moved in the axial direction of the screw rod 11 by the holding nut 23 having the first position adjusting female screw portion 16. That's fine. Further, for example, the second support portion 53 may be moved in the axial direction of the screw rod 11 by the support nut 55 having the second position adjusting female screw portion 17.

The adjustment of the inclination angle between the pair of support surfaces 52a and 53a is performed so that, for example, the second support surface 53a of the second support portion 53 is horizontal, that is, the axial direction of the screw rod 11 is the vertical direction. . A specific method for adjusting the inclination angle between the pair of support surfaces 52a and 53a is the same as in the first embodiment.
For example, when it is necessary to position the second support surfaces 53a of the second support portions 53 of the plurality of support legs 2 on the same plane, adjustment of the interval and the inclination angle between the pair of support surfaces 52a and 53a described above. As in the first embodiment, the base plate portion F2 of the structure F or the adjustment plate (not shown) is placed on the second support surface 53a of the second support portion 53 of the plurality of support legs 2. It is preferable to carry out.

After adjusting the distance between the pair of support surfaces 52a and 53a and the inclination angle, the first support portion 52 and the pair of holding members 14 are sandwiched by the pair of holding nuts 23, as in the first embodiment. The first support portion 52 and the pair of holding members 14 are held immovable with respect to each other. Thereby, the space | interval and inclination angle of a pair of support surfaces 52a and 53a which were set by the above-mentioned adjustment are maintained.
Thereafter, the pair of locking nuts 71 are moved so that the pair of holding nuts 23 are sandwiched by the pair of locking nuts 71. Thereby, it can prevent that a pair of holding nut 23 loosens.

Finally, the installation of the structure F on the installation surface G is completed by installing the structure F on the second support surfaces 53a of the plurality of second support portions 53.
When installing the structure F on the second support surface 53 a of the second support portion 53, the support leg 2 may be fixed to the structure F by the fixing nut 57. When fixing the support leg 2 to the structure F, first, a part of the screw rod 11 protruding from the second support surface 53a of the second support portion 53 is penetrated in the base plate portion F2 of the structure F. The base plate portion F2 is placed on the second support surface 53a of the second support portion 53 by being inserted through the hole F4. Thereafter, the fixing nut 57 is screwed onto the screw rod 11, and the base plate portion F2 is sandwiched between the fixing nut 57 and the supporting nut 55 of the second supporting portion 53, whereby the support leg 2 is structured F. Fixed to.
In the above description, the base plate portion F2 of the structure F is sandwiched between the fixing nut 57 and the supporting nut 55. For example, the device F1 of the structure F is interposed between the fixing nut 57 and the supporting nut 55. The bottom may be sandwiched.

As explained above, according to the support leg 2 of this embodiment, there exists an effect similar to 1st embodiment.
That is, after adjusting the distance between the support surfaces 52a and 53a of the pair of support portions 52 and 53 and the inclination angle of the support surfaces 52a and 53a of the pair of support portions 52 and 53, the second support portion 53 Since the structure F can be arranged on the two support surfaces 53a, the height and inclination of the structure F installed on the installation surface G can be easily adjusted.
Further, even if the structure F is removed from the installation surface G, the support legs 2 can be arranged on the installation surface G, so that the structure F can be re-adjusted without adjusting the height and inclination of the structure F again. F can be installed on the installation surface G.

  Furthermore, the support leg 2 of this embodiment can also be removed from the installation surface G together with the structure F. Even in this case, the inclination angle between the support surfaces 52a and 53a of the pair of support portions 52 and 53 can be held at a desired angle by the pair of holding female screw portions 15, and each of the position adjusting female screw portions 16 and 17 can Since the support portions 52 and 53 can be held at desired positions in the axial direction, the structure F can be installed on the installation surface G again without adjusting the height and inclination of the structure F again.

Moreover, in the support leg 2 of this embodiment, the 2nd support part 53 which supports the lower surface F2b of the structure F is the 2nd support part 13 of 1st embodiment comprised as a leg part which supports the installation surface G. Compared to the configuration, the support leg 2 can be manufactured at low cost.
Moreover, according to the support leg 2 of this embodiment, it becomes possible to support the structure F more stably. That is, the weight on the first end side of the screw rod 11 provided with the first support portion 52 and the pair of holding members 14 is the same as that on the second end portion side of the screw rod 11 provided with the second support portion 53. However, in the support leg 2 of the present embodiment, since the first support surface 52a of the first support portion 52 supports the installation surface G, the center of gravity of the support leg 2 can be set low. Therefore, compared with the case where the first support portion 52 is disposed on the structure F side, the structure F is stabilized even if the rigidity of the screw rod 11 is reduced by reducing the diameter of the screw rod 11 or the like. And can be supported.

In the second embodiment, the fixing nut 57 may be formed integrally with the screw rod 11, for example. That is, the screw rod 11 may be constituted by a bolt, for example.
In this case, since the support leg 2 remains fixed to the structure F, the adjustment of the distance between the support surfaces 52a and 53a of the pair of support portions 52 and 53 and the support surfaces of the pair of support portions 52 and 53 are supported. Adjustment of the inclination angle between 52a and 53a needs to be performed in a state where the structure F is arranged on the installation surface G.

However, even in this configuration, the support portions 52 and 53 are held at desired positions in the axial direction of the screw rod 11 (bolts) by the position adjusting female screw portions 16 and 17, and a pair of support portions is also provided. Since the inclination angle between the support surfaces 52a and 53a of the 52 and 53 is held at a desired angle by the pair of holding female screw portions 15, if the interval and the inclination angle between the pair of support surfaces 52a and 53a are adjusted once, There is no need to adjust these again. Therefore, when removing the structure F from the installation surface G and installing the structure F on the installation surface G again, there is no need to adjust the height and inclination of the structure F again. That is, the height and inclination of the structure F installed on the installation surface G can be easily adjusted.
In addition, even if the structure F installed on the installation surface G receives external force due to wind, earthquake, or the like, the structure F can be prevented from swinging with respect to the installation surface G due to the structure of the support legs 2.

  Further, in the configuration in which the support leg 2 is fixed to the structure F in advance, when adjusting the distance and the inclination angle between the pair of support surfaces 52a and 53a, the portion of the support leg 2 (screw) Only the lower end portion of the rod 11 and parts (the first support portion 52, the holding nut 23, and the locking nut 71) may be operated. That is, it is not necessary to operate the parts and parts (particularly the fixing nut 57) of the support leg 2 arranged on the structure F side. Therefore, the height and inclination of the structure F installed on the installation surface G can be easily adjusted. This effect is particularly useful when the fixing nut 57 is located inside the device F1.

  Although the details of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.

  For example, in all the embodiments described above, the spherical concave surface 19 is formed on the first support portions 12 and 52 and the spherical convex surface 18 is formed on the pair of holding members 14. The spherical convex surface 18 may be formed on the first support parts 12 and 52 and formed on the holding member 14.

  Also, the pair of holding female screw portions 15 and the first position adjusting female screw portion 16 that hold the first support portions 12 and 52 and the pair of holding members 14 so as not to move relative to each other include, for example, the inner portions of the pair of holding members 14. The internal thread part formed in a surrounding surface may be sufficient. That is, the holding member 14 may be screwed to the screw rod 11. In this case, the holding nut 23 of the above embodiment is not necessary, and the number of components of the support legs 1 and 2 can be reduced.

  Further, the support legs of the present invention are not limited to supporting a plurality of structures as in the above-described embodiment, but can also support a structure by one.
