  According to the above configuration, the column member 3 is fixed by the first plate portion 6a and the wedge 40 inserted through the second insertion hole 7e, and the wedge 40 inserted through the second plate portion 6b and the first insertion hole 7d. It can be fixed at two places. Therefore, when the mounted portion 10 is a horizontally extending horizontal portion, and the horizontal portion is vertically sandwiched between the first pressing portion 11 and the second pressing portion 12 as shown in FIG. If the wedge 3 is inserted and fixed in the first insertion hole 7d in a state where the member 3 is rotated to the second plate portion 6b side, the column member 3 can be fixed at a position perpendicular to the attached portion 10. .

  In addition, the attached portion 10 is a vertical portion protruding vertically, and when this vertical portion is sandwiched between the first pressing portion 11 and the second pressing portion 12 as shown in FIG. As shown in FIG. 2, when the wedge member 40 is inserted and fixed in the second insertion hole 7e in a state in which the column member 3 is rotated to the first plate portion 6a side, the column member 3 is fixed to the attached portion 10. Can be fixed at a vertical position.

  Therefore, according to the column apparatus 1 of the present example, the column member 3 can be mounted in a vertical state with respect to the mounted part 10 regardless of whether the mounted part 10 is a horizontal part or a vertical part.

  Moreover, although not shown in figure, when the to-be-attached part 10 is an inclined part which inclined diagonally and this inclined part is clamped by the 1st press part 11 and the 2nd press part 12, for example of the connection member 5 The support frame 7 is formed in a fan shape, and pin holes that can be opposed to each other at an arbitrary position of the support frame 7 and the column member 3 are provided, and the pins are inserted into these pin holes so that the column member 3 is covered. You may make it fix in the position which becomes perpendicular | vertical with respect to the attaching part 10. FIG.

  Although not described in detail, as shown in FIG. 1 and FIG. 2, handrail attachment members 25 are provided on the upper end and the middle portion of the column member 3 of this example, and the column device 1 is attached to the slab of the building. When using as a support for a temporary handrail provided in a parapet or the like, a plurality of support devices 1 are installed at a predetermined interval, and a handrail member (not shown) is bridged between the handrail attachment members 25 of the adjacent support devices 1. Thus, a temporary handrail can be installed.

  Next, the first pressing portion 11 and the second pressing portion 12 that can attach the fixing member 2 to the attached portion 10 while sandwiching the attached portion 10 will be described in detail.

  As shown in FIGS. 1, 2, and 4, the first pressing portion 11 of this example can be brought into contact with the mounted portion 10 and the distance from the second pressing portion 12 can be adjusted by a feed screw mechanism. The adjustment part 13 and the connection arm 14 which connects the adjustment part 13 and the bottom frame 6 of the connection member 5 are provided.

  Specifically, as shown in FIG. 4, the adjustment portion 13 of this example includes a cylindrical outer cylinder 15 fixed to the second plate portion 6 b of the connection member 5 via the connection arm 14, and an outer cylinder 15. 4, a cap 16 having a U-shaped cross-section provided so as to cover the upper opening, a bolt member 17 inserted into the outer cylinder 15 through an opening 16 a provided in the bottom of the cap 16, and a bolt An inner cylinder 18 having a nut portion 18a screwed into a thread groove formed in the shaft portion 17a of the member 17, and a mounted portion 10 connected to the lower end in FIG. A dish-shaped contact portion 19 capable of contacting is provided. In addition, in this example, although the adjustment part 13 is connected with the shaft member 4 via the connection member 5, you may connect with the shaft member 4 directly.

  Here, since the opening 16a provided in the bottom portion of the cap 16 has a larger diameter than the diameter of the shaft portion 17a of the bolt member 17, the bolt member 17 inserted through the opening 16a can rotate to the cap 16. Retained.

  Further, in this example, with the bolt member 17 rotatably held by the cap 16, the nut 21 is screwed onto the shaft portion 17 a of the bolt member 17, and the bolt head 17 b and the nut 21 of the bolt member 17 are The bolt member 17 is prevented from moving in the axial direction across the bottom of the cap 16.

Furthermore, in this example, the nut 24 is overlapped with the fixed nut 23 to form a double nut so that the bolt is not loosened.

  However, the mechanism for preventing the inner cylinder 18 from rotating with respect to the outer cylinder 15 is not limited to the one described above. For example, the outer cylinder 15 and the inner cylinder 18 may be formed in a prismatic shape to prevent rotation. In this way, the guide shaft 22 and the nuts 23 and 24 are not necessary, and the number of parts can be reduced.

  According to the above configuration, when the bolt member 17 is rotated in the loosening direction, the inner cylinder 18 having the nut portion 18a moves downward on the shaft portion 17a of the bolt member 17 in FIG. Since the to-be-attached part 10 is pressed, the force which clamps the to-be-attached part 10 increases.

  Further, the long hole 18c provided in the inner cylinder 18 of the present example is set to a length such that the guide shaft 22 contacts the upper end of the long hole 18c before the inner cylinder 18 comes out of the shaft portion 17a of the bolt member 17. Therefore, there is no fear that the bolt member 17 is rotated too much and the inner cylinder 18 is detached from the bolt member 17.

  On the contrary, when the bolt member 17 is rotated in the tightening direction, the inner cylinder 18 moves upward in FIG. 4 on the shaft portion 17a of the bolt member 17, and the distance between the first pressing portion 11 and the second pressing portion 12 is reached. Are separated.

  Thereby, the holder part 44 and the wedge 45 of this example can attach the holding member 43 to an arbitrary position in the axial direction with respect to the outer cylinder 15, and the holding member 43 in the circumferential direction with respect to the outer cylinder 15. It can be mounted at any angle.

  Therefore, according to the baseboard holding member 42 of this example, the holder portion 44 is slid with respect to the outer cylinder 15, the wedge 45 is inserted into a wedge insertion hole (not shown), and the holder portion 44 is fixed to the outer cylinder 15. For example, since the distance between the gripping member 43 and the attached portion 10 can be arbitrarily set, the baseboard 41 having different heights can be held.

  Further, according to the baseboard holding member 42 of this example, even when the thickness of the baseboard 41 is thinner than the width of the concave portion of the gripping portion 46, as shown in FIG. The holder 45 is inserted into a wedge insertion hole (not shown) and the holder portion 44 is fixed to the outer cylinder 15 in a state where the grip portion 46 is tilted until it abuts against the baseboard 41 and is held in place. it can.

  Therefore, according to the baseboard holding member 42 of this example, various baseboards 41 having different heights and thicknesses can be attached to the column apparatus 1.

  However, the structure of the attachment means is not limited to the above.

  In this example, the baseboard holding member 42 is provided for the first pressing portion 11 of the fixing member 2, but the baseboard holding member 42 may be provided. However, as in this example, when the outer cylinder 15 of the first pressing portion 11 of the fixing member 2 is provided, the grip portion 46 can be made compact because the distance from the installation location of the baseboard 41 is short.

  Although the preferred embodiments of the present invention have been described in detail above, it is obvious that modifications, changes and modifications can be made without departing from the scope of the claims.
