また図１〜図３に示すように、手摺支柱１の下端部には、この手摺支柱１の下部とコンクリートスラブ５の表面の防水層６との間を覆う足元カバー２１が設けられている。この足元カバー２１は、塩化ビニル等の合成樹脂により角錐台形状に一体形成されたもので、上面側には手摺支柱１の横断面形状より僅かに大きい方形状の開口部２１ａが形成され、下端面は開放状態となっている。また、上面側開口部２１ａには、その周辺に沿ってシール用コーキング材１７を装填する凹段部２１ｂが周設され、また下端面外周部にもシール用コーキング材１７を装填する凹段部２１ｃが周設されている。 As shown in FIGS. 1 to 3, a foot cover 21 is provided at the lower end portion of the handrail support column 1 so as to cover the space between the lower portion of the handrail support column 1 and the waterproof layer 6 on the surface of the concrete slab 5. The foot cover 21 is integrally formed in a truncated pyramid shape with a synthetic resin such as vinyl chloride, and a rectangular opening 21a slightly larger than the cross-sectional shape of the handrail column 1 is formed on the upper surface side. The end surface is in an open state. Further, a concave step portion 21b for loading the sealing caulking material 17 is provided along the periphery of the upper surface side opening portion 21a, and a concave step portion for loading the sealing caulking material 17 on the outer peripheral portion of the lower end surface. 21c is provided around.

次に、上記のように表面に防水層６が設けられた屋上コンクリートスラブ５上に手摺りＴを立設するにあたっての手摺支柱１の取付手順について説明する。 Next, the attachment procedure of the handrail support | pillar 1 in standing up the handrail T on the roof concrete slab 5 in which the waterproof layer 6 was provided on the surface as mentioned above is demonstrated.

先ず、アルミ押出形材からなるアンカー取付部材１６のネジ棒ねじ込み筒１４，１４に一対のアンカー棒８，８の夫々の一端部側を所要長さだけねじ込んで、その他端部側を、アンカー取付部材１６の下端から突出させて、図６に示すような状態のアンカー取付部材１６を手摺支柱１内にその下端部から挿入し、アンカー取付部材１６の下端が手摺支柱１の下端にほぼ位置した状態で、図２に示すように、手摺支柱１の短辺側側壁１ｂの所要箇所からビス２２，２３をアンカー取付部材１６の短辺側側壁部にねじ込むことによって、アンカー取付部材１６を手摺支柱１に対し固定する。 First, one end of each of the pair of anchor rods 8 and 8 is screwed into the screw rod screw-in cylinders 14 and 14 of the anchor attachment member 16 made of an aluminum extruded member by a required length, and the other end is anchored. The anchor mounting member 16 is protruded from the lower end of the member 16 and inserted into the handrail post 1 from the lower end portion thereof as shown in FIG. 6, and the lower end of the anchor mounting member 16 is substantially located at the lower end of the handrail post 1. In this state, as shown in FIG. 2, the screws 22 and 23 are screwed into the short side wall portion of the anchor mounting member 16 from a required portion of the short side wall 1b of the handrail column 1 to thereby fix the anchor mounting member 16 to the handrail column. 1 fixed.

一方、コンクリートスラブ５上の支柱取付位置には、その表面の防水層６から、室内側及び室外側の一対のアンカー用穴９，９を穿設し、そして各アンカー用穴９に、エポキシ樹脂のような熱可塑性樹脂からなる好ましくは速乾性の接着用樹脂１０を充填する。 On the other hand, a pair of indoor and outdoor anchor holes 9 and 9 are drilled from the waterproof layer 6 on the surface of the column mounting position on the concrete slab 5, and an epoxy resin is formed in each anchor hole 9. Preferably, a quick-drying adhesive resin 10 made of such a thermoplastic resin is filled.

また、手摺支柱１から突出した室内外両アンカー棒８，８をアンカー用穴９，９に挿入するのに先立って、手摺支柱１の下端部には足元カバー２１を嵌め込んで取り付け、両アンカー棒８，８には夫々ナット１３を螺合し、このナット１３の下側にメガネ形のワッシャー１２Ｗ及びシールパッキン１１Ｗを挿通させておく。 Prior to inserting the indoor and outdoor anchor rods 8 and 8 protruding from the handrail support column 1 into the anchor holes 9 and 9, the foot cover 21 is fitted and attached to the lower end of the handrail support column 1 so that both anchors are attached. A nut 13 is screwed into each of the rods 8 and 8, and a glass-shaped washer 12 W and a seal packing 11 W are inserted under the nut 13.

しかして、接着用樹脂１０を充填した支柱取付位置の室内外両アンカー用穴９，９に、手摺支柱１の下端から突出した室内側及び室外側両アンカー棒８，８を所要深さまで挿入して埋め込み、接着用樹脂１０が固化してアンカー用穴９，９内に根固めした後、ナット１３を締め付けることによりワッシャー１２Ｗを介しシールパッキン１１Ｗを防水層６に押し付け、それによって防水層６のアンカー用穴部９ａと、アンカー用穴９内に挿入されたアンカー棒８との間を水密シールする。 Thus, the indoor and outdoor anchor rods 8, 8 protruding from the lower end of the handrail post 1 are inserted to the required depth into the indoor / outdoor anchor holes 9, 9 at the support mounting position filled with the adhesive resin 10. After the adhesive resin 10 is solidified and solidified in the anchor holes 9, 9, the nut 13 is tightened to press the seal packing 11W against the waterproof layer 6 through the washer 12W. A watertight seal is provided between the anchor hole 9 a and the anchor rod 8 inserted into the anchor hole 9.

この時、即ち接着用樹脂１０が固化してアンカー棒８がアンカー用穴９，９内に根固めされた状態にある時、手摺支柱１が正常な鉛直姿勢に対し傾いているような場合は、前記ビス２２，２３を一旦取り外して、手摺支柱１を鉛直姿勢に修正しながら再びビス２２，２３をアンカー取付部材１６の所要箇所に対してねじ込むか、あるいは当初のビスねじ込み箇所とは別の箇所から適当な長さのビスをねじ込んで、手摺支柱１に対するアンカー取付部材１６の挿入角度を微妙に調整することにより、手摺支柱１を正常な鉛直姿勢に修正することができる。いずれにしても、手摺支柱１の内周面とこれに対しスライド可能に挿入されるアンカー取付部材１６との間の微小隙間を利用して、手摺支柱１側の適当箇所からビスをねじ込んでアンカー取付部材１６の適当箇所を圧接固定することによって、手摺支柱１の取付姿勢を修正することができる。 In this case, that is, when the adhesive resin 10 is solidified and the anchor bar 8 is in a state of being anchored in the anchor holes 9 and 9, the handrail column 1 is inclined with respect to the normal vertical posture. Then, the screws 22 and 23 are once removed, and the screws 22 and 23 are screwed again into a required position of the anchor mounting member 16 while correcting the handrail column 1 to the vertical posture, or different from the initial screw screwing position. By screwing in a screw of an appropriate length from a location and finely adjusting the insertion angle of the anchor attachment member 16 with respect to the handrail support column 1, the handrail support column 1 can be corrected to a normal vertical posture. In any case, using a small gap between the inner peripheral surface of the handrail support column 1 and the anchor mounting member 16 slidably inserted thereto, screws are screwed in from appropriate locations on the handrail support column 1 side to anchor The attachment posture of the handrail column 1 can be corrected by fixing the appropriate position of the attachment member 16 by pressure contact.

その後、足元カバー２１を防水層６に接地するように引き下ろして、図２に示すように上面側開口部側の凹段部２１ｂ及び下端面外周部の凹段部２１ｃに夫々コーキング材１７を装填し、手摺支柱１の下端部と防水層６との間をシールする。
Thereafter, pulls down to ground the foot cover 21 in the waterproof layer 6, recessed step portion of the upper surface side opening side as shown in FIG. 2 21 b and the lower end surface peripheral portion respectively caulk the recessed step 21 c 17 And the space between the lower end portion of the handrail support column 1 and the waterproof layer 6 is sealed.

上記のような取付装置によれば、ナット１３を締め付けることによりワッシャー１２Ｗを介してシールパッキン１１Ｗが防水層６に押し付けられ、それによって防水層６のアンカー用穴部９ａと、アンカー用穴９内に挿入されたアンカー棒８との間が積極的に水密シールされ、それによってまたアンカー用穴９内への雨水等の浸入が阻止され、コンクリートスラブ５内部への浸水が阻止され、従って建物内部への漏水が防止される。 According to the mounting device as described above, the seal packing 11W is pressed against the waterproof layer 6 via the washer 12W by tightening the nut 13, whereby the anchor hole 9a of the waterproof layer 6 and the anchor hole 9 The space between the anchor rod 8 and the anchor rod 8 is positively sealed with water, thereby preventing intrusion of rainwater or the like into the anchor hole 9 and preventing the water from entering the concrete slab 5. Leakage of water is prevented.

また、手摺支柱１の下端から室内側と室外側とに位置する一対のアンカー棒８，８を突設しているから、手摺りＴの使用時に、手摺りＴが受ける風圧によって手摺支柱１に対しこれと直交する室内外方向の外力が作用しても、その外力を室内外両側のアンカー棒８，８が有効に支持し、その外力による手摺支柱１の倒れを防止することができる。 In addition, since the pair of anchor rods 8 and 8 located on the indoor side and the outdoor side are protruded from the lower end of the handrail post 1, when the handrail T is used, the handrail T receives the handrail T by the wind pressure received by the handrail T. On the other hand, even if an external force in the indoor / outdoor direction perpendicular to this acts, the anchor rods 8 on both sides of the indoor / outside effectively support the external force, and the handrail column 1 can be prevented from falling due to the external force.

さらに、手摺支柱１の下端部に、手摺支柱１の下部とコンクリートスラブ５表面の防水層６との間を覆う足元カバー２１を設けたことにより、手摺支柱１の下端から突出して露出するアンカー棒８、シールパッキン１１及びナット１３を足元カバー２１によって隠蔽でき、外観上の体裁を良くすることができる上に、手摺支柱１の下端部への浸水を防止でき、アンカー棒８及びナット１３の腐食を極力抑えることができる。 Further, an anchor bar that protrudes from the lower end of the handrail post 1 and is exposed by providing a foot cover 21 that covers the lower part of the handrail post 1 and between the lower part of the handrail post 1 and the waterproof layer 6 on the surface of the concrete slab 5. 8. The seal packing 11 and the nut 13 can be concealed by the foot cover 21, the appearance can be improved, the water can be prevented from entering the lower end of the handrail post 1, and the anchor rod 8 and the nut 13 are corroded. Can be suppressed as much as possible.

図２、図３に示す実施形態では、シールパッキン１１は一対のアンカー棒挿通孔１９，１９を設けたメガネ形パッキン１１Ｗからなるものであり、またワッシャー１２は一対のアンカー棒挿通孔２０，２０を設けたメガネ形ワッシャー１２Ｗからなるものであるが、シールパッキン１１は、図４の(c) に示すように各アンカー棒８に夫々１つずつ取り付ける普通のシングルパッキン１１Ｓを使用してもよく、またワッシャー１２も、図４の(a) 及び(b) に示すように各アンカー棒８に夫々１つずつ取り付ける普通のシングルワッシャー１２Ｓを使用してもよい。 In the embodiment shown in FIGS. 2 and 3, the seal packing 11 is composed of a glasses-shaped packing 11 </ b> W provided with a pair of anchor rod insertion holes 19, 19, and the washer 12 is a pair of anchor rod insertion holes 20, 20.
