  As shown in FIGS. 1 (a) and 1 (b), elongated holes 7 and 7 for injecting a grout material long in the vertical direction are formed on the opposite side walls 5a and 5a on the lower end side of the square-shaped handrail support column 5. In addition, the grout material that is long in the vertical direction flows into the opposite side walls 4a and 4a on the supporting column mounting base 4 on which the handrail supporting column 5 is externally fitted at a position where it can face-to-face with each supporting column side long hole 7 A long hole 8 is formed.

  Further, as shown in FIG. 1A, the handrail support column 5 is provided with a bolt insertion hole 10 at the lower end portion of the other side wall 5b, and the required portion of the side wall 4b of the support column mounting base 4 is long in the vertical direction. A long hole 11 for adjusting the fixed position is provided, and a bolt 12 with a washer is inserted between the bolt insertion hole 10 and the fixed position adjusting long hole 11 and tightened with a nut 13 with a washer. The lower end part of the support | pillar 5 can be fixed to the support | pillar attachment base material 4 in a required height position. The fixing position adjusting long hole 11 provided in the support mounting base 4 also functions as a grout material pouring long hole similar to the grout material pouring long holes 7 and 8.

  FIGS. 3A to 3C show the pouring state of the grout material 6 injected into the column mounting hole 2 when the handrail column 5 is fixed to the column mounting base 4 in the column mounting hole 2. It is a thing. The grout material 6 is a cement-based non-shrink grout material, which is a blend of cement, aggregate, non-shrink material, and the like. Become.

  First, when the lower end portion of the handrail support column 5 is externally fitted and fixed to the anchor hardware 3 in the support column mounting hole 2, the upper end of the support column side long hole 7 is more than the upper surface of the weir wall as shown in FIG. The base-side long hole 8 is partially superposed with the support-side long hole 8 at the upper position, and the lower end of the base-side long hole 8 is positioned lower than the lower end of the support-side long hole 7. In the state where the sliding column 5 is externally fitted to the column mounting base 4 and fixed at the required height position, the grout material is injected between the outer peripheral side of the lower end of the railing column 5 and the inner peripheral side of the column mounting hole 2. When the hose 17 is inserted and the grout material 6 is injected into the column mounting hole 2, the grout material 6 is attached to the column mounting base 4 at the inner bottom portion of the column mounting hole 2 as shown in FIG. The space portion S between the handrail column 5 and the column mounting base 4 from the base-side elongated hole 8 of the column mounting base 4 while gradually collecting around Further, the grout material 6 passes from the outer peripheral side of the handrail strut 5 through the strut-side long hole 7 and the handrail strut 5 and the strut mounting base 4 as shown in FIG. It flows into the space portion S between the two and flows into the column attachment base material 4 from the base material side long hole 8.

  Accordingly, when the grout material 6 is stopped from being injected by the grout material injection hose 17 when the grout material 6 overflows on the outer peripheral side of the handrail support column 5 in the column attachment hole 2, The upper surface level of the space portion S between the column mounting base 4 and the grout material 6 in the column mounting base 4 is substantially flush with the weir wall upper surface 1a as shown in FIG. In addition, what is necessary is just to scrape off the grout material 6 which overflowed from the support | pillar attachment hole 2 on the outer peripheral side of the handrail support | pillar 5 in the state where it is flush with the dam wall upper surface 1a when it becomes a dry state.

  In the pouring of the grout material 6 into the pillar mounting hole 2 as described above, the long hole 7 on the handrail pillar 5 side has a function of pouring the grout material 6 from the outside of the handrail pillar 5 to the inside thereof, and is long. Since the upper end of the hole 7 is positioned higher than the dam wall upper surface 1a, the air inside the support column 5 is released, and the grout material 6 can be easily poured into the support column 5, and the handrail support column 5 After the attachment, when rainwater or the like accumulates in the space S between the handrail support column 5 and the support attachment base 4, it has a function of discharging the accumulated rainwater or the like to the outside (see FIG. 2).

  In addition, when the lower end portion of the handrail support column 5 is externally fixed to the support attachment base material 4, the vertically long base material side long hole 8 partially overlaps with the vertically long support column side long hole 7, Since the handrail support column 5 is fitted and fixed to the column attachment base material 4 so that the lower end of the base material side long hole 8 is positioned lower than the lower end of the support column side long hole 7, A grout material 6 can be quickly and easily poured into the column mounting base 4 from the column side long hole 7 through the substrate side long hole 8. In addition, although the support | pillar side long hole 7 and the base material side long hole 8 can each be provided with two or more with respect to the handrail support | pillar 5 and the support | pillar attachment base material 4, if the number increases, the intensity | strength of the support | pillar 5 and the base material 4 will become. In order to fall, it is preferable to provide two on the opposite side walls 5a, 5a and 4a, 4a as in the embodiment.

Moreover, there is no possibility that rainwater or the like enters the inside of the column mounting base 4.

  Further, in this embodiment, the support mounting base 4 has a cylindrical shape, but the support mounting base 4 may be solid. However, when the support mounting base 4 is formed in a solid shape, the material cost is high, so that it is preferable that the support mounting base 4 has a cylindrical shape as in the embodiment.

  Further, when the support mounting base 4 is formed in a cylindrical shape, the base 4 does not necessarily have the elongated hole 8 for pouring the grout material, but on the upper side in the handrail support 5. If rainwater or the like that has entered may enter the support base 4, the lower side of the support base 4 may corrode. Accordingly, as shown in this embodiment, the strut mounting base material 4 is provided with the elongated holes 8 for pouring the grout material, so that the grout material 6 is also connected to the weir wall upper surface 1a in the strut mounting base material 4 as well. It can be filled to almost the same level, so that the inside of the column mounting base 4 can be sealed, and the column mounting base 4 is held by the grout material 6 from both the inner peripheral side and the outer peripheral side. The base material 4 can be firmly fixed in the column attachment hole 2.

  Moreover, in embodiment, the bolt insertion hole 11 is provided in the lower end part of the handrail support | pillar 5, the long hole 10 for fixing position adjustment is provided in the cylindrical support | pillar mounting base material 4, and these bolt insertion hole 10 and fixing position adjustment A bolt 12 is inserted into the long hole 11 and tightened with a nut 13 to fix the lower end portion of the handrail support column 5 to the support mounting base 4 at a required height position. You may make it hold | maintain the handrail support | pillar 5 with a suitable holding means from the outside in the state which fitted the lower end part of the handrail support | pillar 5 to the support | pillar attachment base material 4 in a required height position without using. However, according to the configuration as in the embodiment, the handrail support column 5 can be easily and easily held at the required height position with respect to the support column mounting base material 4, and the fixed position provided on the column mounting base material 4 side. The pouring of the grout material 6 into the support mounting base 4 can be promoted by the adjustment long hole 10.

  And in the attachment structure of the handrail support | pillar which concerns on this invention, as shown in FIG. 2, the upper end of the support | pillar side long hole 7 of the support | pillar side long hole 7 is located higher than the dam wall upper surface 1a, and the support | pillar mounting hole 2 Since the top surface level of the grout material 6 injected and solidified into the rail is substantially flush with the weir wall top surface 1 a inside and outside the handrail support column 5, rainwater or the like is attached to the upper end portion of the handrail support column 5. Intrusion into the handrail strut 5 by a capillary phenomenon through a small gap such as a coupling portion with a cap or a screw hole, and the rainwater or the like that has entered the space S between the handrail strut 5 and the strut mounting base 4 If it accumulates, the rainwater etc. can be discharged from the upper part of the column side long hole 7 to the outside of the handrail support column 5, so that damage to the handrail support column 5 due to the intrusion of rainwater etc. is reliably avoided. can do.

  Further, since the grout material 6 to be injected into the column mounting hole 2 is made of cement-based non-shrink grout material, the upper surface level of the grout material 6 in the column mounting hole 2 immediately after construction is substantially flush with the upper surface 1a of the weir wall 1. If it is in a state, the grout material 6 can maintain its upper surface level even after curing.
