It is inserted into the bolt hole 33 formed in the portion and the bolt hole 34 formed in the end portion of the receiving bracket 23, and the lateral member 22 is attached to the column 21 via the receiving bracket 23 and the covering bracket 25 by the nut 35. At this time, since the through hole 36 formed in the covering metal 25 is formed larger than the head of the receiving metal mounting bolt 27, the horizontal member 22 is temporarily placed on the receiving metal 23, and then the covering 25 is attached to the column 21. Can be fixed to.

  Another example of a horizontal member mounting bracket for a protective fence for mounting a horizontal member on a support is disclosed in Patent Document 2. Hereinafter, the horizontal member mounting bracket for the protective fence is referred to as a conventional mounting bracket B and will be described with reference to the drawings.

  FIG. 13 is a perspective view showing a conventional mounting bracket B. FIG.

  As shown in FIG. 13, the conventional mounting bracket B is formed such that the contact surface 38 with the support column 37 is recessed and the bolt hole 39 of the horizontal member mounting bolt is formed on the upper surface.

  In order to horizontally attach the horizontal member 40 to the support column 37 with the conventional mounting bracket B, the conventional mounting bracket B is fixed to the support column 37 with fixing bolts 41 as shown in FIG.

  In order to attach the horizontal member 40 to the support column 37 by using the conventional mounting bracket B, the conventional mounting bracket B is tilted along the contact surface 38 in the vertical plane and fixed by the fixing bolt 41 as shown in FIG. To do.

  In order to attach the transverse member 40 at an angle in the horizontal plane, the conventional mounting bracket B is rotated along the contact surface 38 in the horizontal plane and fixed by the fixing bolt 41 as shown in FIG.

  One embodiment of the protective fence transverse member mounting bracket of the present invention will be described with reference to the drawings.

  FIG. 1 is a plan view showing a method of attaching a horizontal member to a support column using the protective member mounting member for a protective fence according to the present invention. FIG. 2 is an attachment method of the horizontal member to the support member using the horizontal member mounting member for a protective fence according to the present invention. FIG. 3 is a front view showing the method, FIG. 3 is a perspective view of a state in which the horizontal member is attached to the column by the horizontal member mounting bracket for protective fence of the present invention, and FIG. 4 is a horizontal member for the protective fence of the present invention. FIG. 5 is another perspective view of the state in which the horizontal member is attached to the column with the mounting bracket as viewed obliquely from above. FIG. 5 is a view of the state in which the horizontal member is mounted on the column with the horizontal member mounting bracket for the protective fence according to the present invention. FIG.

  In this embodiment, the beam member is used as the transverse member. However, the present invention is not limited to this, and it may be a body edge material, a panel body frame material, or the like.

  As shown in FIGS. 1 to 5, the horizontal member mounting bracket C (hereinafter simply referred to as a horizontal member mounting bracket C) for a protective fence according to the present invention is a pair of horizontal members that are mounted on the column 2 with the column 2 interposed therebetween. It consists of mounting bracket main bodies 1a and 1b. Both sides of the horizontal member mounting bracket main bodies 1 a and 1 b are formed in a semi-cylindrical shape in accordance with the outer diameter of the horizontal member 3.

  An engaging portion 5 that engages with the opening 4 formed in the support column 2 is formed on the inner surface of the central portion of the horizontal member mounting bracket main body 1a, 1b. The engaging portion 5 is composed of an upper emboss 6 and L-shaped lower claws 15 b formed on the horizontal member mounting bracket main bodies 1 a and 1 b below the upper emboss 6. Details of the engaging portion 5 will be described later.

  As in the conventional mounting brackets A and B, the engaging portion 5 is formed in the horizontal member mounting bracket main bodies 1a and 1b, and the engaging portion 5 is inserted into the opening 4 of the column 2 and engaged with the opening 4. The fixing bolt which fixes these to a support | pillar becomes unnecessary.

  Bolt holes 8 through which the horizontal member mounting bolts 7 are inserted are formed at both ends of the horizontal member mounting bracket main bodies 1a and 1b.

  Temporary placement portions 9 of the transverse member 3 are formed at the lower ends of both ends of the horizontal member mounting bracket main bodies 1a and 1b, and an interval (L1) is formed between the temporary placement portions 9 (see FIG. 5). By forming the interval (L1), as shown in FIG. 5, when the vertical beam 10 is attached to the horizontal member 3, it is possible to prevent interference between the vertical beam 10 and the horizontal member mounting bracket main bodies 1a and 1b.

  A cutout 11 into which the end of the horizontal member 3 is inserted is formed at the upper corners of both ends of the horizontal member mounting bracket main bodies 1a and 1b. By forming the notch 11, temporary placement of the transverse member 3 on the temporary placement portion 9 is facilitated.

  A space (L2) is formed between the column 2 and the horizontal member mounting bracket main bodies 1a and 1b (see FIG. 1). By forming the interval (L2), after the horizontal member mounting bracket C is mounted on the support column 2, the horizontal member mounting bracket C can be tilted within a predetermined angle range in the vertical plane with the protrusion 5 as the center. It becomes possible.

  In order to attach the horizontal member 3 to the column 2 with the horizontal member mounting bracket C, the following is performed.

  First, as shown in FIGS. 1 and 2, the engaging portions 5 of the horizontal member mounting bracket main bodies 1 a and 1 b are inserted into the openings 4 formed in the support column 2. Thereby, the horizontal member mounting bracket main bodies 1a and 1b are temporarily fixed to both sides of the support 2 with the support 2 interposed therebetween. That is, since the lower claw 15b (see FIG. 6c) formed in an L shape of the engaging portion 5 is formed and the lower claw 15b engages with the lower portion of the opening 4, the horizontal member mounting bracket main bodies 1a and 1b are It is temporarily fixed without coming off the support 2.

  Next, the end of the horizontal member 3 is placed on the temporary placement portion 9 from above the notch 11 of the horizontal member mounting bracket main bodies 1a and 1b, and the horizontal member 3 is mounted on the horizontal member mounting bracket main bodies 1a and 1b (horizontal Temporarily placed on the member mounting bracket C) (see FIGS. 1 and 2).

  Next, the horizontal member mounting bolt 7 is inserted into the bolt hole 8 of the horizontal member mounting bracket main body 1 a, 1 b and the bolt hole 12 of the horizontal member 3, and fixed by the nut 13. As a result, the horizontal member 3 is fixed to the horizontal member mounting bracket C, and the horizontal member mounting bracket main bodies 1a and 1b are in a state of sandwiching the column 2. Therefore, the horizontal member mounting bracket main bodies 1a and 1b are It is fixed without rattling.

  As described above, the horizontal member 3 can be attached to the support column 2 by the horizontal member mounting bracket C.

  In order to attach the horizontal member mounting bracket C to the support column 2 by inclining, the horizontal member mounting bracket main bodies 1a and 1b may be rotated around the engaging portion 5 as shown by a two-dot chain line in FIG. Since a gap (L2) is formed between the support column 2 and the horizontal member mounting bracket C, the horizontal member mounting bracket C can be rotated around the engaging portion 5 within a predetermined angle range.

  Further, as shown in FIG. 5, since the gap (L1) is formed between the temporary placement portions 9 of the horizontal member mounting bracket main bodies 1a and 1b, when the vertical beam 10 is attached to the horizontal member 3, the vertical beam 10 and Interference with the horizontal member mounting bracket main bodies 1a and 1b can be prevented.
