In this case, the tip of the drill is not displaced and the work becomes easy. In addition, the bondability between the first and second support arms and the support can be improved.

  The present invention comprises a first and second support arms that rise from a substrate portion inclined at a predetermined angle with respect to a horizontal plane and are bent inward from each other and arranged to face each other with a predetermined interval. In addition, a structure for fixing the column legs that can adjust the mounting angle of the columns mounted on the first and second support arms has been realized.

  Hereinafter, the present invention will be described in detail with reference to the drawings illustrating an embodiment. FIG. 1 is a perspective view showing an example of a fixing structure for a column leg according to the present invention, and FIG. 2 is a side view showing the structure for fixing a column leg according to the present invention. Here, the support structure 10 of the support | pillar leg part is for attaching a support | pillar on concrete or a head, Comprising: The board | substrate part 11 mounted on the said concrete or the head, and stand up from this board | substrate part 11 The substrate portion 11 is inclined at a predetermined angle with respect to a horizontal plane, and the first and second support arms 12 and 13 are folded inward from each other. It is curved and is arranged opposite to each other with a predetermined interval.

  The substrate portion 11 has a shallow groove 11a on the center upper surface, and the work of making a bolt hole when fixing with an anchor bolt or the like is easy. Further, shallow grooves 11b are also formed in the upper surface of both end portions of the substrate portion 11 along the longitudinal direction. The first support arm 12 is erected so that the substrate portion 11 is substantially vertical with the substrate portion 11 tilted at a predetermined angle, for example, 4 to 7 °. Similarly, the second support arm 13 is also erected so as to be substantially vertical with the substrate portion 11 tilted by a predetermined angle.

  The first support arm 12 is slightly inclined by θ in the outward direction from the rising edge to the parallel surface portion 12a. For example, it is about 3 to 5 °. The parallel surface portion 12a is formed on the outer surface of the first support arm 12, and has minute irregularities. The minute irregularities are formed by, for example, knurling. On the other hand, from the parallel surface portion 12a to the tip, it is inclined inward by θ. For example, it is about 3 to 5 °.

  The second support arm 13 is slightly inclined in the outward direction from the rising edge to the parallel surface portion 13a by θ. For example, it is about 3 to 5 °. The parallel surface portion 13a is formed on the outer surface of the second support arm 13 and has minute irregularities. The minute irregularities are formed by, for example, knurling. On the contrary, from the parallel surface portion 13a to the tip, it is inclined inward by θ. For example, it is about 3 to 5 °.

  A method of using the support structure 10 for a column leg according to the present invention configured as described above will be described. First, as shown in FIG. 3, the board | substrate part 11 is mounted directly on the upper surface of the concrete parapet 14, and it fixes with the anchor bolt 15 embed | buried in the parapet. At this time, the upper surface of the parapet 14 is inclined at a predetermined angle, but the inclination angle is not necessarily uniform. That is, the lower surface of the base plate portion 11 has an inclination enough to match the inclination of the upper surface of the parapet, but if the inclination of the upper surface of the parapet is not uniform, the first and second support arms erected from here are It is no longer vertical. Therefore, in the present invention, the first support arm 12 and the second support arm 13 are bent inward, respectively, and the insertion angle of the attached square cylindrical column 16 can be finely adjusted. After the support column 16 is adjusted vertically, the parallel surface portions 12a and 13a of the first support arm 12 and the second support arm 13 are fixed with a tapping screw 17 with a drill. Since the parallel surface portions 12a and 13a are the portions where the outer distance between the first support arm 12 and the second support arm 13 is the maximum, the parallel surface portions 12a and 13a are always in contact with the inner peripheral surface of the columnar column. Moreover, since the micro unevenness | corrugation is formed in the parallel surface part, bondability with the internal peripheral surface of the support | pillar 16 improves.

  FIG. 4 is a cross-sectional view of an essential part showing a case in which a column is fixed on a metal headboard using the column leg fixing structure of the present invention. In this embodiment, the mounting bracket 21 is first fixed on the concrete parapet 14 or the like by the anchor bolt 15. With the mounting bracket 21, the aluminum headboard 19 is attached, and the board portion 11 is mounted thereon and attached with a tapping screw 20 with a drill. At this time, the tapping screw 20 is screwed so as to penetrate the aluminum headstock 19 and reach the mounting bracket 21. The procedure for adjusting the insertion angle of the column 16 with respect to the first support arm 12 and the second support arm 13 of the substrate unit 11 is the same as described above. In this way, a top rail or the like can be mounted on the aluminum headboard 19.

  FIG. 5 shows an example in which a handrail member (top rail) 18 is installed on a support column 16 erected from the parapet 14. The pillars 16 are erected vertically at predetermined intervals, and handrail members are attached in a shape connecting the tops of the pillars.
