Next, an example of the installation method when the support column 10 is installed on the support column fixing device 20 will be described in detail with reference to FIGS. 5 to 9. First, as shown in FIG. 5, the sleeve 41 with a female stitch is embedded at a predetermined position on the installation surface S. Subsequently, as shown in FIG. 6, the base portion 21 is arranged so that the position of the anchor hole 24 is aligned with the position of the sleeve 41, and the anchor bolt 40 is inserted from the anchor hole 24 via the washer 42 and the spring washer 43. Screw in toward the sleeve 41. The base portion 21 is fixed to the installation surface S by fastening the anchor bolt 40 to the sleeve 41.

Next, as shown in FIGS. 7 and 8, the support column fixing member 23 is arranged between the upright walls 22 and 22 standing on the base portion 21, and the disk portion 28 of the support column fixing member 23 is placed on the connecting portion 25. Place. Subsequently, the lower end portion 11 of the support column 10 is inserted into the internal space K.

Here, as shown in FIGS. 3, 8 and 9, the lower end portion 11 of the support column 10 has a through hole 11a penetrating in the front-rear direction, and one of the through holes 22a of one of the upright walls 22 Through the through hole 28a of the disk portion 28 of the support column fixing member 23, the through hole 26a of the fixing wall 26, and the through hole 11a, the bolt 51 is passed through each through hole (not shown) on the opposite side, and the bolt 51 The nut 52 is screwed in from the penetrating tip side.

As a result, the support column 10 can rotate in the R1 direction or the R2 direction with the bolt 51 as an axis. Therefore, even if the base portion 21 is fixed along the inclined surface, the support column 10 is arranged in the vertical direction. Can be fixed. In the embodiment, the columns 10 are arranged in the substantially vertical direction, but can be arranged at a predetermined angle with respect to the vertical direction.

Subsequently, by screwing the nut 52 to the bolt 51, the support column fixing member 23 and the lower end portion 11 of the support column 10 are fixed between the upright walls 22 and 22 in the set arrangement direction of the support column 10. The arrangement direction of the support column 10 may be adjusted when the bolt 51 is penetrated through each member and the nut 52 is screwed in and temporarily fixed, or before the bolt 51 is penetrated.

The upright wall 22 has a guide portion 29 on the inner wall side so that the disk portion 28 can smoothly rotate around the bolt 51. In the present embodiment, as shown in FIG. 6, in the guide portion 29, the upper side end portions of the upright wall 22 are inclined inward and downward, and the inclined surface 29a facing the center side in the left-right direction of the upright wall 22 is provided on the inner wall surface thereof.

The placed disk portion 28 regulates the movement regardless of the arrangement direction of the support column 10, and the inclined surface 29a restricts the movement in the upward and lateral directions, so that rattling is unlikely to occur. That is, even if the installation position of the disk portion 28 is deviated, the bolt 51 moves to the center side of the upright wall 22 along the inclined surface 29a by fastening the bolt 51, so that the disc portion 28 can be firmly fastened.

The inclined surface 29a is formed flat in this embodiment, but the shape is not limited as long as the movement in the upward direction and the horizontal direction with respect to the disk portion 28 can be regulated. The guide portion 29 can be easily created by bending the upright wall 22, but the width in the front-rear direction of the bending can be set to the fixed wall 26 if the thickness of the disk portion 28 is not exceeded. It is preferable because it does not cause interference such as contact with.

In order to firmly fix the lower end portion 11 of the support column 10 to the support column fixing member 23, as in this embodiment, another through hole 26b is formed in the pair of fixing walls 26 at a position different from the through hole 28a, and one of the bolts 53 is attached. The nut 54 may be screwed through the through hole 26b of No. 1 through another through hole 11b at the lower end portion 11 and through each through hole (not shown) on the opposite side.

Next, an attachment method in which the panel body 30 is attached between the columns 10 fixed by using the column fixing device 20 to form the fence F will be described with reference to FIG. FIG. 10 is an explanatory view showing an example of a method of installing the panel body 30 of the fence F according to the present invention. In the present embodiment, the panel body 30 is a grid-like panel in which the vertical members 31 and the horizontal members 32 are arranged in a grid pattern, but the panel body 30 is not limited to this.
In the present embodiment, the fixed wall 26 has a notch 26c notched over the entire left-right direction in the central portion in the vertical direction, and the notch 26c communicates in the front-rear direction. On the other hand, the lower end portion 11 of the support column 10 has a through hole 11c leading to the notch portion 26c when viewed from the front.

Subsequently, the panel body 30 is arranged on the front surface side of the support column 10, and the cross member 32 of the panel body 30 is arranged in the cutout portion 26c. Then, a rod-shaped fixture 60 having a J-shaped hook portion 61 capable of locking the cross member 32 on one side and a screw portion 62 on the other side is inserted from the notch portion 26c on the front side through the through hole 11c to the rear side. The nut 63 is screwed into the notch 26c of the cross member 32, and is pulled toward the lower end 11 side of the support column 10 of the cross member 32 to be fixed. As a result, as shown in FIG. 4, the cross member 32 of the panel body 30 is fixed to the support column 10. The fixing position of the cross member 32 may be above the support column fixing device 20, but as in this embodiment, the lower end portion of the panel body 30 is installed as much as possible by having the fixing wall 26 have the notch portion 26c. Since it can be fixed in a state of being close to the surface S, the gap between the panel body 30 and the installation surface S can be narrowed.

Although the support column fixing device of the present invention has been described above based on the embodiment, the present invention is not limited to this embodiment. The scope of the present invention also includes various modifications that can be conceived by those skilled in the art within the scope of the present invention.

For example, in the above embodiment, the standing walls 22 are connected to each other through the connecting portion 25, but the standing walls 22 may be joined to the upper surface of the base portion 21 without the connecting portion 25. In this case, the disk portion 28 is preferably placed on the upper surface of the base portion 21.

Further, in the above embodiment, the disk portion 28 may be placed on the connecting portion 25 within the range in which the support column 10 can be arranged. As described above, when the connecting portion 25 is not provided, it may be mounted on the upper surface of the base portion 21 within the range in which the support column 10 can be arranged. Therefore, for example, only the lower part may be semi-disc-shaped.

11 to 14 are explanatory views showing another embodiment according to the present invention, FIG. 11 is a perspective view showing another embodiment according to the present invention, and FIG. 12 is a line BB of FIG. An enlarged cross-sectional view, FIG. 13 is a partially omitted end view taken along line BB of FIG. 11, and FIG. 14 is an explanatory view showing the positional relationship of each through hole in the view taken along the line C of FIG. The support column fixing device 20 according to this embodiment is different from the support column fixing device 20 shown in FIGS. 1 to 10 in the form of the upright wall 22 and the support column fixing member 23, which will be described. Other than that, the same components as those already described are designated by the same reference numerals, and the description thereof will be omitted. In FIG. 13, the boundary of each through hole is indicated by a dashed line.

First, the column fixing member 23 will be described. As shown in FIG. 11, in the two side walls 27 on the left and right of the fixing wall 26 of the support column fixing member 23, one side wall 27 is a notch portion cut out in the width direction from the middle portion in the vertical direction to the front-rear direction. The side wall 27 has 27a, and the other side wall 27 has a protruding portion 27b that protrudes in the front-rear direction from the intermediate portion in the vertical direction. Be fitted.

As a result, when the support column 10 is fixed to the support column fixing device 20 and then a load is applied to the support column 10 from the front to the rear, the front side of the support column 10 acts to be relatively lifted or extended in the vertical direction. Therefore, the bolt 51 penetrating the support column 10 acts in the direction in which the front side is lifted, and acts so that only the front side of the support column fixing member 23 is lifted in conjunction with the bolt 51, but the upright wall 22 is fixed to the base portion 21. Therefore, a shearing force acts on the bolt 51, which may deform the bolt 51. Therefore, by fitting the front and rear side walls 27 to each other as in the present embodiment, it is possible to suppress the lifting of the front side of the support column fixing member 23 and suppress the deformation of the bolt 51.

Next, the relationship between the through holes 22a, 28a, and 26a will be described in more detail. The through hole 22a of the upright wall 22, the through hole 28a of the disk portion 28, and the through hole 26a of the fixed wall 26 are arranged in this order. The whole is arranged so as to be located in the through hole 28a. Further, the through hole 26a has a smaller diameter than the through hole 28a, and the entire through hole 26a is arranged in the through hole 28a in the front view.

Further, the through hole 22a has a lower edge portion 22b at a position lower than that of the lower edge portion 26d of the through hole 26a. On the other hand, the upper edge portion 22c of the through hole 22a is at the same height as or lower than the upper edge portion 26e of the through hole 26a. In this embodiment, the through holes 22a and 26a have a circular shape having substantially the same diameter, and the center of the through holes 26a is located slightly above the center of the through holes 22a.

Since the inner diameters of the through holes 22a, 28a, and 26a are larger than the outer diameter of the bolt 51, the bolt 51 can be penetrated. The dimension L in the direction is narrow.

In this embodiment, since the dimension L is equal to or larger than the outer diameter of the bolt 51, the bolt 51 can penetrate along the penetration direction of each through hole, but it is more difficult to penetrate than only one of the through holes 22a and 26a. .. Here, since the through holes 22a and 26a are separated in the through hole by the large diameter through hole 28a, the bolt 51 can be made into the through hole by slightly lifting the screw tip side of the bolt 51 and making it slightly slanted. It becomes easy to penetrate 22a and 26a.

Further, the through hole 22a has a tapered portion 22d whose diameter is gradually increased toward the lower end portion 11 side of the support column 10 from the middle of the penetration direction. As a result, the distance at which the bolt 51 is difficult to penetrate is shortened.

Further, the through hole 26a has a tapered portion 26f whose diameter is gradually increased toward the lower end portion 11 side of the support column 10 from the middle of the penetration direction. As a result, the distance at which the bolt 51 is difficult to penetrate is shortened. In addition, since it becomes easy to slightly lift the screw tip end side of the bolt 51 and make it slightly slanted, it becomes easy to pass through the through hole 26a.

The dimension L may be smaller than the outer diameter of the bolt 51 due to a slight processing error of each member, surface treatment or surface coating of each member, but as described above, the bolt 51 is slightly slanted. At the same time, by press-fitting in the penetrating direction, the through holes 22a, 28a and 26a can be passed through.

Next, the screw tip of the bolt 51 passes through the through hole 26a, passes through the through hole 11a of the lower end 11a of the support column 10, and the screw tip side of the bolt 51 is slightly lifted and is arranged in an oblique direction to penetrate the opposite side. When it reaches the vicinity of the hole 26a, a part of the screw tip may come into contact with the tapered portion 26f, but if the bolt 51 is press-fitted in the penetrating direction, the screw tip will be a through hole along the inclined surface of the tapered portion 26f. It can be guided to the back of 26a and pass through.

Even when the bolt 51 advances further and passes near the through hole 22a on the opposite side, the screw tip portion can be guided by the inclined surface of the tapered portion 22d of the through hole 22a and pass through the through hole 22a.

In a state of penetrating between the through holes 22a and 22a, the bolt 51 is biased to the upper part of the through hole 22a at a relatively low position, and is biased to the lower part of the through hole 26a at a relatively high position. It is passing.

As a result, the bolt 51 passes through the upper portion of the through hole 22a at a relatively low position in a biased manner, so that the upward movement is suppressed. Further, the upward movement of the support column fixing member 23 is suppressed by the bolt 51 that passes unbalancedly to the lower part of the through hole 26a. That is, after the nut 52 is screwed to the bolt 51 and fastened, the upward movement of the support column fixing member 23 having the through hole 26a is suppressed, so that the vertical rattling of the support column fixing member 23 is suppressed. be able to.

The present invention is particularly useful as a strut fixing device for fixing a strut to which a panel body is attached when a multi-story parking lot, an existing fence, a fence, or the like is removed and a fence is re-installed on a concrete or block base. It can be widely used when installing with a fence in a multi-story parking lot or a base with many slopes.
