枠組足場の組立にあたっては、先ず図４の(a) に示すように、枠組足場の設置される床面上に２枚の敷板２６，２６を平行に敷設し、これら敷板２６，２６上に、支柱２９の下端部にジャッキベース２７を備えた矩形枠状の調節枠２８を一定間隔おきに建て込み、対向する調節枠２８間には本発明に係る安全手摺Ｔ（設置高さの低めのもの）を設置する。この場合、調節枠２８の支柱２９がＨ型建枠４の脚柱１に相当し、この支柱２９の上下所要部には安全手摺Ｔを取り付けるロックピン１２が突設されている。安全手摺Ｔを設置した後、レベル調整し、対向する調節枠２８，２８間に足場板６を架け渡す。各調節枠２８の支柱２９の上端部には、Ｈ型建枠４を建て込む際に上段側脚柱１の下端部１ｂに嵌合する連結ピン２９ａが突設されている。   When assembling the frame scaffold, first, as shown in FIG. 4 (a), two floor plates 26, 26 are laid in parallel on the floor surface on which the frame scaffold is installed, and on these floor plates 26, 26, A rectangular frame-shaped adjustment frame 28 provided with a jack base 27 is built at the lower end of the support column 29 at regular intervals, and the safety handrail T (with a lower installation height) according to the present invention is placed between the opposed adjustment frames 28. ). In this case, the support column 29 of the adjustment frame 28 corresponds to the pedestal 1 of the H-shaped building frame 4, and the lock pin 12 for attaching the safety handrail T projects from the upper and lower required portions of the support column 29. After installing the safety handrail T, the level is adjusted and the scaffold plate 6 is bridged between the adjustment frames 28 and 28 facing each other. A connecting pin 29 a that projects into the lower end 1 b of the upper-side pedestal 1 when the H-shaped building frame 4 is installed projects from the upper end of the column 29 of each adjustment frame 28.

上記のように１段目足場を組み立てた後、図４の(b) に示すように、作業者が１段目足場の足場板６の上で、各調節枠２８にその支柱２９の連結ピン２９ａを介してＨ型建枠４を建て込む。全ての調節枠２８にＨ型建枠４を建て込んだならば、図４の(c) に示すように、互いに対向するＨ型建枠４，４の対向する脚柱１，１に安全手摺Ｔ（調節枠２８の場合よりも高さの高いもの）を取り付ける。   After assembling the first stage scaffold as described above, as shown in FIG. 4 (b), the operator can connect the connecting pin of the support 29 to each adjustment frame 28 on the scaffold board 6 of the first stage scaffold. The H-shaped building frame 4 is installed through 29a. When the H-shaped building frame 4 is built in all the adjustment frames 28, as shown in FIG. 4 (c), safety handrails are placed on the opposite pedestals 1 and 1 of the H-shaped building frames 4 and 4 facing each other. Attach T (having a height higher than that of the adjustment frame 28).

こうしてＨ型建枠４，４の互いに対向する脚柱１，１に安全手摺Ｔを取り付けた後、図５の(a) に示すように、作業者は１段目足場の足場板６上でＨ型建枠４，４の互いに対向する横架材２，２間に２段目足場の足場板６を架け渡し、そして階段３０を取り付ける。この後、作業者は、階段３０から２段目足場の足場板６の上に上がって、図５の(b) に示すように、既設のＨ型建枠４にその脚柱１の連結ピン１ａを介して次のＨ型建枠４を建て込む。以降は、上記の作業を繰り返し行って、枠組足場を多段状に組み立てる。   Thus, after attaching the safety handrail T to the opposite pillars 1 and 1 of the H-shaped building frames 4 and 4, as shown in FIG. The scaffolding plate 6 of the second-stage scaffolding is bridged between the horizontal members 2, 2 of the H-shaped building frames 4, 4 facing each other, and the stairs 30 are attached. Thereafter, the worker goes up from the stairs 30 onto the scaffolding plate 6 of the second stage scaffold, and as shown in FIG. 5 (b), the connecting pin of the pedestal 1 is attached to the existing H-shaped building frame 4. The next H-shaped building frame 4 is built through 1a. Thereafter, the above work is repeated to assemble the frame scaffold in a multistage shape.

以上説明したように、本発明に係る安全手摺Ｔは、水平杆７と、夫々上端部８ａ，９ａにロックピン挿通孔１０，１０を有し、水平杆７の下方に配置される一対の斜杆８，９とからなるもので、水平杆７と両斜杆８，９とを組付けるには、両斜杆８，９の夫々上端部８ａ，９ａを夫々ロックピン挿通孔１０，１０の手前側で水平杆７の両端部７ａ，７ｂに枢着すればよいから、組み付け作業が非常に簡単容易となって、製作コストの低廉化を図ることができる。また、この安全手摺をＨ型建枠４に取り付けるには、両斜杆８，９の夫々上端部８ａ，９ａのロックピン挿通孔１０，１０を、対向する両Ｈ型建枠４，４の脚柱１，１の上部側ロックピン１２，１２に挿通した後、両斜杆８，９をＸ状に交差させて、両斜杆８，９の夫々下端部８ｂ，９ｂのロックピン挿通孔１１，１１を、脚柱１，１の下部側ロックピン１２，１２に夫々挿通すればよいから、取り付けも簡単容易である。   As described above, the safety handrail T according to the present invention has the horizontal hook 7 and the pair of diagonally arranged shafts 10 and 10 at the upper end portions 8a and 9a. In order to assemble the horizontal rod 7 and the two inclined rods 8 and 9, the upper end portions 8a and 9a of the two inclined rods 8 and 9 are respectively connected to the lock pin insertion holes 10 and 10, respectively. Since it is only necessary to pivotally attach to both end portions 7a and 7b of the horizontal rod 7 on the front side, the assembling work becomes very simple and easy, and the production cost can be reduced. Further, in order to attach this safety handrail to the H-shaped building frame 4, the lock pin insertion holes 10, 10 of the upper end portions 8 a, 9 a of the two leaning rods 8, 9 are provided on the opposing H-shaped building frames 4, 4. After passing through the upper side lock pins 12 and 12 of the pedestals 1 and 1, the two leaning rods 8 and 9 are crossed in an X shape, and the lock pin insertion holes in the lower end portions 8b and 9b of the two leaning rods 8 and 9, respectively. 11 and 11 need only be inserted into the lower lock pins 12 and 12 of the pedestals 1 and 1, respectively, so that the mounting is easy and easy.

更に、この安全手摺Ｔの製作にあたって、水平杆７を製作するには、丸鋼管を所定長さにカットしたものの両端部を夫々プレス加工により扁平状に圧潰して扁平端部７ａ，７ｂを形成し、これらの扁平端部７ａ，７ｂに例えばリベット孔１３やボルト挿通孔等の枢着用ピン孔を穿設すればよく、また斜杆８，９の製作もほとんと同様であって、丸鋼管を所定長さにカットしたものの両端部を夫々プレス加工によって扁平状に圧潰して扁平端部８ａ，９ａ、８ｂ，９ｂを形成し、斜杆８，９の上端側扁平端部８ａ，９ａにはロックピン挿通孔１０，１０を穿設し、下端側扁平端部８ｂ，９ｂにはロックピン挿通孔１１，１１を穿設すればよいから製作が簡単となる。   Further, in producing the safety handrail T, in order to produce the horizontal rod 7, both ends of a round steel pipe cut to a predetermined length are crushed into flat shapes by press working to form flat end portions 7a and 7b. The flat end portions 7a and 7b may be provided with pivot mounting pin holes such as rivet holes 13 and bolt insertion holes, and the production of the inclined rods 8 and 9 is almost the same. Are cut into a predetermined length to form flat end portions 8a, 9a, 8b, 9b, respectively, and flat end portions 8a, 9a of the inclined rods 8, 9 are formed. Since the lock pin insertion holes 10 and 10 are drilled and the lock pin insertion holes 11 and 11 are formed in the lower flat end portions 8b and 9b, the manufacture is simplified.

そして、この場合、両斜杆８，９の夫々上端部８ａ，９ａにはロックピン挿通孔１０，１０の手前側に上向きに突出する取付片１４，１４を固着して、両取付片１４，１４に水平杆７の両端部７ａ，７ａを夫々リベット１６等を介して枢着することにより、水平杆７と一対の斜杆８，９とを互いに平行に折り畳むことが可能となる。   In this case, mounting pieces 14 and 14 projecting upward on the front side of the lock pin insertion holes 10 and 10 are fixed to the upper end portions 8a and 9a of the two inclined rods 8 and 9, respectively. 14, both ends 7a and 7a of the horizontal rod 7 are pivotally attached via rivets 16 or the like, so that the horizontal rod 7 and the pair of inclined rods 8 and 9 can be folded in parallel to each other.
