It is -A sectional drawing. In this embodiment, the column holder P includes a base portion 1 that is fixed to the installation surface, and a cylindrical portion 3 that is erected upward from the base portion 1 and into which the lower end portion 21 of the column 2 is fitted. The column 2 is fixed to the installation surface via the column holder P.

  In this embodiment, the base portion 1 has a plate shape that is formed in a rectangular shape in plan view with the thickness direction being up and down, and a cylindrical portion 3 is erected at the center thereof. And the cylindrical part 3 is inserted in the penetration part 11 which leads to the lower surface provided in the center part of this base part 1, and is joined by welding. As described above, in this embodiment, the base portion 1 and the cylindrical portion 3 which are separate bodies are joined and formed. For example, the cylindrical portion 3 is placed on the peripheral edge of the penetrating portion 11. The form joined by welding etc. may be sufficient and what formed the base part and the cylindrical part integrally using cast iron, aluminum alloy, etc. may be used.

  As shown in FIG. 1, the column 2 fixes the fence panel 4. In this embodiment, the column 2 also supports the gate panel 5. However, the fence 2 may be fixed only. The strut 2 is generally a square pipe-shaped steel pipe that is stable in strength and inexpensive, but may be a polygonal cross-section or a round pipe-shaped steel pipe as long as it can be supported by the strut holder P. . Moreover, the thing using other metals, such as a stainless alloy and an aluminum alloy, may be used.

  In this embodiment, the support column 2 is inserted into the cylindrical portion 3 of the support column holder P. However, although not shown, the support column 2 may be externally inserted into the cylindrical portion 3. If it is a form which can fix the support | pillar 2 to 3 firmly, it will not specifically limit.

  In this embodiment, the cylindrical portion 3 is formed by forming a front wall portion 31 and a rear wall portion 32 with a gap 33 in the front and rear, and the front wall portion 31 and the rear wall portion 32 are The support 2 is inserted between them. More specifically, the front wall portion 31 has a U-shaped cross section including a front wall 31a and left and right side walls 31b and is opened rearward, and the rear wall portion 32 has a left and right side wall 32a. The side wall 32b has a U-shaped cross-section and is opened forward. The front wall portion 31 and the rear wall portion 32 are arranged with the openings facing each other, and a gap 33 exists between the opposite ends of the left and right side walls 31b, 32b. The lower end portion 21 of the support column 2 is inserted between the portion 31 and the rear wall portion 32.

  A structure for fixing the column 2 to the cylindrical portion 3 will be described with reference to FIG. In the cylindrical portion 3, the front wall 31a and the rear wall 32a are provided with a pair of through-holes 31c and 32c that penetrate in the front-rear direction above and below, respectively. After the lower end 21 of the column 2 is moved downward from above the column holder P and inserted between the front wall 31 and the rear wall 32, the fixing bolt 34 is inserted from the through hole 31c, and the lower end of the column It passes through the through hole 22 formed in the portion 21, further penetrates the through hole 32 c of the rear wall portion 32, and is screwed into the nut 37 via the washer 35 and the spring washer 36. Then, the column 2 can be fixed as shown in FIG. 2 by tightening the nut 37 to the fixing bolt 34 and sandwiching the column 2 inserted between the front wall 31a and the rear wall 32a.

  Although the shape of the front wall part 31 and the rear wall part 32 is not restricted to a cross-sectional U shape, the form which can support the support | pillar 2 firmly is preferable. For example, when the support column 2 has a circular cross section, the shapes of the front wall portion 31 and the rear wall portion 32 may be semi-cylindrical shapes according to the shape thereof. Further, the front wall portion 31 and the rear wall portion 32 may use a metal other than steel, and may integrally form the column holder P using cast iron, an aluminum alloy, or the like.

  Next, the relationship between the fence 2 and the fence panel 4 will be described in detail. The front wall portion 31 of the column holder P is formed with a cutout portion 38 that is cut out in the lateral direction, and the lower end portion 21 of the column 2 inserted into the column holder P is exposed from the cutout portion 38. . The lower end of the fence panel 4 is inserted into the notch 38 and is attached to the front surface of the column 2 by a fixing member 39.

  In general, when the horizontal beam 41 of the fence panel 4 is fixed to the column 2, if the horizontal beam 41 that can contact the column is manufactured so that the front and rear positions are aligned, the horizontal beam 41 is attached to the column 2 through the notch 38. By fixing, it can fix so that malfunctions, such as a distortion, may not arise in the up-down direction of the fence panel 4. FIG. In the case where the cutout portion 38 is not provided, although not shown, it may be fixed to the crosspiece 41 on the front wall 31a of the tubular portion 3 via the fixing member 39. In this case, it is preferable that the front and rear positions of the horizontal rails 41 be positioned forward by the thickness of the front wall 31a so that the above-described problems are unlikely to occur.

  Reinforcing portions 6 are provided on the outer wall surfaces of the center portions of the side wall 31b and the side wall 32b, respectively. In this embodiment, the reinforcing portion 6 is formed of a vertically long rectangular flat plate as viewed from the side, and is welded to the side wall 31b and the side wall 32b so as to project the thickness thereof.

  Next, the relationship between the installation surface and the column holder P will be described. An insertion hole 12 penetrating vertically is formed at the corner of the base portion 1, and as shown in FIG. 4, a female screw anchor 13 is previously provided below the installation surface. Then, the anchor bolt 15 is inserted into the insertion hole 12 through the washer 14 and fastened to the female screw anchor 13, thereby fixing the base portion 1 on the installation surface. In this embodiment, one insertion hole 12 is provided at each of the four corners of the base portion 1, but it is only necessary that the base portion 1 can be firmly fixed to the installation surface, and the number of formation of the insertion holes 12 is not particularly limited. Further, by forming the insertion hole 12 in a horizontally long plan view oval shape as in the present embodiment, a slight misalignment of the female screw anchor 13 can be absorbed by the insertion hole 12.

  For example, although not shown, the anchor bolt 15 may have a form in which all screw bolts embedded in advance on the installation surface are passed through the insertion hole 12 and are inserted upward and fastened with a fastener such as a nut.

  The base portion 1 is provided with a notch groove 16 that is cut out in the vertical direction at the peripheral end portion of the base portion 1. One end of the notch groove 16 reaches the peripheral end of the base portion 1, and the other end reaches between the insertion holes 12. In this embodiment, a part of the base portion 1 is left between the distal end side of the notch groove 16 and the cylindrical portion 3 to form a notch remaining portion 17. Further, since the insertion holes 12 are provided at the four corners of the base portion 1, a total of four notch grooves 16 are formed between the insertion holes 12. That is, the base portion 1 is divided into four dividing portions 18 each having one insertion hole 12 by the notch groove 16, and the dividing portion 18 is connected to each other by the notch remaining portion 17.

  As a result, when the single divided portion 18 is fixed to the installation surface through the anchor bolt 15 in the insertion hole 12, even if unevenness occurs on the installation surface or gravel is present, the divided portion 18 may be fixed in a state in which the notch 17 is elastically deformed or plastically deformed and slightly inclined to form a clearance from the installation surface with the notch remaining portion 17 as an axis. Since it is not easily affected by the elastic deformation or plastic deformation of the dividing portion 18, it can be firmly fixed to the installation surface.

  Furthermore, in this embodiment, the through portion 11 is provided in the central portion of the base portion 1, so that even if the deformation occurs in one of the divided portions 18, the other divided portions 18 further influence the deformation. It becomes difficult to receive.

  Further, even if the deformation can occur in two or more divided portions 18, the remaining divided portions 18 are not easily affected. Therefore, the two divided portions 18 can be deformed according to the situation of the divided portions 18 and the installation surface. Therefore, the base portion 1 can be more firmly fixed to the installation surface as compared with the case where the notch groove 16 is not provided.

  The dividing portion 18 includes at least the vicinity of the insertion hole 12 when adjacent insertion holes 12 are divided by the notch groove 16 therebetween. That is, in this embodiment, one insertion hole 12 is provided with a notch groove 16 between two adjacent insertion holes 12, but one of the two adjacent insertion holes 12 is one of the two insertion holes 12. Even when the notch groove 16 is provided only between the insertion hole 12, the insertion holes 12 are separated from each other by the notch groove 16, so that the vicinity of one of the insertion holes 12 is slightly deformed. However, the effect of the deformation is small in the vicinity of the other insertion hole 12 due to the notch groove 16. Therefore, in the base part 1, if there is at least one notch groove 16, it can be more firmly fixed to the installation surface.

  In this embodiment, the cutout groove 16 is formed so as to be substantially orthogonal to the peripheral end surface of the base portion 1 formed in a substantially rectangular shape in plan view, but approaches the one insertion hole 12 from the peripheral end surface, and the other It may be provided so as to be away from the insertion hole 12, or may be branched from the middle of the notch groove 16.

FIG. 5 shows another embodiment, and is an explanatory view of the vicinity of the support holder.
In this embodiment, compared with the column holder P shown in FIGS. 1 to 4, the form of the base portion 1 is mainly different, and the same components as those already described are denoted by the same reference numerals, Description is omitted. That is, the column holder P according to the present embodiment has a plurality of cutout grooves 16 arranged in parallel in the base portion 1. In the present embodiment, three cutout grooves 16 are arranged in parallel. The cutout groove 16 forms a cut portion 18 including the insertion hole 12 and a cut piece 19 cut off by the two cutout grooves 16 arranged side by side without including the insertion hole 12. Similarly to the column holder P shown in FIG. 2, the base portion 1 is partially left between the tip of the notch groove 16 and the cylindrical portion 3 to form a notch remaining portion 17. The dividing part 18 and the divided piece 19 are connected via 17.

  Thereby, when fixing to the installation surface through the anchor bolt 15 in the insertion hole 12 of the base portion 1, even if unevenness has occurred on the installation surface where the fraction piece 19 is arranged or gravel is present, There is a possibility that a slight gap may be formed between the lower surface of the divided piece 19 and the installation surface due to elastic deformation or plastic deformation of the divided piece 19, but the divided portion 18 is not easily affected by the deformation of the divided piece 19. Therefore, the dividing portion 18 can be firmly fixed to the installation surface via the anchor bolt 15.

  In this embodiment, a total of four pieces 19 are formed between the insertion holes 12 of the base portion 1, but it is sufficient that at least one piece 19 is formed. Further, the segment piece 19 is not limited to a pair of two pieces, but may be a form in which one notch segment 19 is formed by arranging two notch grooves 16 between the insertion holes 12. One or more pieces may be formed, and three or more pieces 19 may be formed.

  Since the present invention can firmly support the column on the column holder, it can only be used as a column column or a column column for a gate used in the fence. Instead, it can be suitably used as a support for a fence in which a beam material is installed between the support and the support used for a fence or a vehicle stop.
