Description

  The present invention relates to a handrail post mounting device for a handrail installed on a concrete frame, and more particularly to a handrail post mounting device suitable for a handrail installed around a land roof on a building roof.

  As a conventional attachment structure of a handrail support, for example, there is one described in Patent Document 1 below. This is fixed by screwing one end side of each of the pair of anchor bolts into the bolt screw-in cylinder part of the handrail strut made of aluminum extrusion mold material, and projecting the other end side from the lower end of the handrail strut. Each of the protruding end portions is embedded in anchor holes drilled in the concrete frame and solidified with an adhesive resin, so that the handrail support column is attached and fixed to the concrete frame in an upright state.

According to such an attachment structure, the attachment work of the handrail support becomes extremely simple and easy, and the handrail construction cost can be reduced.
JP-A-2005-226376

  In the mounting structure of the handrail support as described above, the other end of the anchor bolt, which is fixed by screwing one end directly into the handrail support, is embedded and fixed in the concrete frame. When the handrail is subjected to a large wind pressure and a large external force is applied to the handrail post in the indoor / outdoor direction, even if the anchor bolt is strongly rooted in the anchor hole of the concrete frame with adhesive, Since a large external force acting directly acts on the anchor bolt, the anchor hole portion of the concrete frame may be damaged, and the handrail support column may fall in the indoor / outdoor direction.

  In view of the above circumstances, the present invention can easily install and install the handrail strut, and even if a large external force is applied to the handrail strut in the indoor / outdoor direction, it can sufficiently cope with the external force, and the handrail strut can fall down. An object of the present invention is to provide a handrail post attachment device that can be reliably prevented.

  Means for solving the above problems will be described with reference numerals in the embodiments described later. The handrail post mounting device of the invention according to claim 1 includes a rectangular plate-like base portion 8 and an upper surface thereof. A mounting frame 10 comprising a cylindrical frame portion 9 projecting from the center is disposed on the concrete housing 5 so that the long width direction of the plate-shaped base portion 8 faces the indoor / outdoor direction. The anchor bolts 11 for fixing the frame to be attached to the four corners of the base 8 are embedded in the anchor holes 12 drilled in the concrete frame 5 and solidified by the adhesive resin 13. The lower end portion of the handrail support column 1 is inserted into the cylindrical frame portion 9 and fixed.

  According to a second aspect of the present invention, in the attachment device for the handrail strut according to the first aspect, the indoor side end portion 9a of the upper surface of the plate-like base portion 8 is provided on the indoor side wall portion 9a and the outdoor side wall portion 9b of the cylindrical frame portion 9. In addition, a reinforcing rib 15 is interposed between the outer end portion 9b and the outdoor end portion 9b.

  Claim 3 is the attachment device for the handrail strut according to claim 1, wherein the mounting frame 10 is an anchor bolt for fixing the frame with the plate-like base 8 placed on the upper surface of the concrete frame 5. 11 is fixed on the concrete frame 5.

  Claim 4 is the attachment apparatus of the handrail support | pillar in any one of Claims 1-3, The mounting base frame 10 is the state which floated the plate-shaped base part 8 from the upper surface of the concrete frame 5 to required height. It is characterized by being fixed on the concrete frame 5 by means of anchor bolts 11 for fixing the frame.

  The effect of the invention by the above-described solution means will be described with reference numerals of embodiments to be described later. According to the invention according to claim 1, the mounting frame 10 is set to the length of the rectangular plate-like base portion 8. For anchors that are arranged on the concrete slab 5 with the width direction facing the indoor / outdoor direction, and anchor bolts 11 that are attached to the four corners of the plate-like base 8 of the mounting frame 10 are drilled in the concrete frame 5. Since the bottom end of the handrail support column 1 is inserted and fixed in the cylindrical frame portion 9 by being embedded in the hole 12 and solidified by the adhesive resin 13, the handrail T has a large wind pressure as in a typhoon or the like.
