It can be detached from the engaging portion 55 by inserting a tool or the like from the lower side.

  Note that the suspension support column 2 and the door support column 3 are usually long enough to embed the lower end of the suspension support column 3 in the concrete base 4 and are erected using a base plate 31 having a support member 30. Cut the buried part and use it. However, the suspension support column 2 and the door support column 3 may be dedicated for construction using the base plate 31.

  In the telescopic gate having the above-described configuration, for example, when the door support column 3 is fixed to the concrete base 4 using the base plate 31, the following procedure is performed. First, anchor bolts 32 are embedded at predetermined positions of the concrete base 4, and the base plate 31 is fixed to the concrete base 4 provided with the support members 30 by the anchor bolts 32 and the nuts 35.

  On the other hand, regardless of whether it is for embedding or not, the door-to-door support column 3 connects a pair of front and rear column bodies 40 to the front and rear by a width determining member 41, a screw 46, etc., and a coupling portion 48 to each column body 40. Each cover 42 is mounted, and each cap body 40 and the cap 43 are mounted on the upper end of the cover 42, and the engaging claw 56 is engaged with the engaging portion 55 of the column body 40.

  In the case of using the buried door-supporting column 3, an anchor is installed in the front-rear direction between the lower ends of the embedded portions of the front and rear column main bodies 40. Therefore, the column main body 40 and the cover 42 of the suspension column 2 are cut from the lower end in a lateral direction at a predetermined dimension to remove the embedded portion, and the vertical dimension of the door-supporting column 3 is adjusted.

  In the assembled door-supporting column 3, the cover 42 attached to the column main body 40 via the coupling portion 48 is restricted from moving upward by the cap 43. However, since the cover 42 can be extracted downward, the cover 42 is extracted downward from the column main body 40 while relatively sliding the fitting concave portion 49 and the fitting convex portion 50 of the coupling portion 48. .

  Then, since the insertion part 53 of the cap 43 covered with the cover 42 is exposed, a tool or the like is inserted between the insertion part 53 and the opposite side wall 45 of the column main body 40 to engage the engagement claw 56 with the engagement part. The cap 43 is removed from the support body 40 upward.

  Next, four attachment holes 47 are formed at intervals corresponding to the screw holes 37 of the support member 30 at the lower part of the opposite side wall 45 of each column body 40. Then, while the front and rear support columns 40 are joined together via the width determining member 41, the lower end opening side is fitted to the upper end of each support member 30 and fitted to the outer peripheral side, and the opposite side walls are fitted. The screw 38 inserted from the attachment hole 47 side of the 45 is screwed into the screw hole 37 of the support member 30, and the opposite side wall 45 of the column main body 40 is fastened to the support member 30.

  As a result, each column main body 40 can be fixed to each support member 30 of the base plate 31. Next, the lower end of the fitting convex portion 50 of the cover 42 is aligned with the upper end of the fitting concave portion 49 of the column main body 40. The cover 42 is inserted and attached along the column main body 40 by the relative sliding of the 50 and the fitting recess 49. Finally, the insertion portions 52 to 54 of the cap 43 are inserted in alignment with the column main body 40 and the cover 42, and the engagement claw 56 of the cap 43 is engaged with the engagement portion 55 of the opposite side wall 45 of the column main body 40. Match.

  In this way, although the column body 40 is fixed to the support member 30 with the screw 38, the head portion 38a can be covered with the cover 42, and the head portion 38a of the screw 38 is not exposed to the outside. Therefore, the appearance of the lower side of the door-supporting column 3 can be improved.

  Further, by attaching the cap 43 and engaging the engaging claw 56 with the engaging portion 55 of the column main body 40, the cap 43 can be fixed to the column main body 40, and the top plate portion 51 can be attached to the upper side of the cover 42. Can restrict movement. Moreover, since the engaging claw 56 and the engaging portion 55 are surrounded by the column main body 40 and the cover 42, it is impossible to remove the cap 43 thereafter, and the cap 43 and the cover 42 are illegally disassembled. There is no fear.

  Further, the column main body 40 is fixed to the support member 30 from the outside with the screw 38, and then all the operations such as attaching the cover 42 and the cap 43 can be performed from the outside, so that the workability is improved and the construction can be easily performed. There is. Further, since the cover 42 may be attached to the side surface of the column main body 40 in spite of covering the head portion 38a of the screw 38 with the cover 42, the structure is very simple, and it is easy and inexpensive at low cost. Can be produced. Moreover, since the cover 42 is detachably coupled to the column main body 40, the strength of the door-to-door column 3 can be expected.

  FIG. 16 illustrates a second embodiment of the present invention. The door-supporting column 3 includes a column main body 40 formed in a rectangular tube shape that is long in the front-rear direction, and a cover 42 that is detachably inserted in the vertical direction on both front and rear sides of the column main body 40 via coupling portions 48.
