【考案の詳細な説明】
この考案は立坑掘削工事等に使用するライチプレート用
昇降タラップの踏段具に関するものである。[Detailed description of the invention] This invention relates to a stepping tool for lifting and lowering ramps for litchi plates used in shaft excavation work, etc.
ライチプレート用のフランジジ間距離、つまり縦幅は例
えば５０ｃｍもあり、このライチプレート用により立坑
を構築した場合、昇降タラップはフランジを利用すると
、踏段のピッチが５０ｃｍにもなり、実用に適しないも
のであった。The distance between the flanges for litchi plates, that is, the vertical width, is, for example, 50 cm, and if a vertical shaft is constructed using these litchi plates, if flanges are used for the lifting gangway, the pitch of the steps will be as much as 50 cm, making it unsuitable for practical use. Met.
また、従来の昇降タラップは、組付けが容易でなく、複
雑な構成をしている等の種々の欠点があった。Further, conventional elevating ramps have various drawbacks, such as not being easy to assemble and having a complicated structure.
そこでこの考案の目的とするところは組付けが簡単で構
造強度が強く、安全且つ容易に昇降が出来る新規なライ
チプレート用昇降タラップの踏段具を提供するにある。Therefore, the purpose of this invention is to provide a new stepping tool for lifting ramps for lychee plates that is easy to assemble, has strong structural strength, and can be lifted and lowered safely and easily.
以下、この考案の一実施例について図面を参照しながら
説明する。An embodiment of this invention will be described below with reference to the drawings.
第１図において符号２０で示すものはこの考案に係る踏
段具である。In FIG. 1, the reference numeral 20 indicates a step according to this invention.
この踏段具２０は以下のように構成される。This stepping tool 20 is constructed as follows.
すなわち、１は踏杆であって滑り止２２としての凹凸の
付いた鋼材から成り、その両端部は弧状の側杆２の先端
部に固着されている。That is, reference numeral 1 denotes a step stick made of a steel material with unevenness as a non-slip member 22, and both ends thereof are fixed to the tips of arc-shaped side sticks 2.
そして、この滑り止め２２は図から明らかな如く、少な
くとも上下面の二面に形成され、踏段具２０の反転使用
の使用の際も不都合のないようにされている。As is clear from the figure, the anti-slip 22 is formed on at least two surfaces, the upper and lower surfaces, so that there is no inconvenience when the step tool 20 is used in reverse.
該側杆２の下端部は曲折されていて固定片３が形成され
、ボルト挿通用の取付穴３ａが該固定片３の平面部分に
穿設されている。The lower end of the side rod 2 is bent to form a fixing piece 3, and a mounting hole 3a for inserting a bolt is bored in the flat part of the fixing piece 3.
つまり、該側杆２は第１，２図から明らかなように、固
定片３から一旦、垂直方向に立上がり、次いて手前側に
その他端部たる先端部が張り出して形成されている。That is, as is clear from FIGS. 1 and 2, the side rod 2 is formed so that it once rises vertically from the fixed piece 3, and then the other end, ie, the tip, protrudes toward the front side.
これにより第１図示の如く、側杆２０の湾曲部下方には
、空間部としての懐部２３が形成され、種々の器具をこ
の空間に位置し得て、また、昇降時の足掛けも確実なも
のとなる。As a result, as shown in the first figure, a pocket 23 as a space is formed below the curve of the side rod 20, and various instruments can be placed in this space, and the footrest can be securely placed when going up and down. Become something.
該側杆２の外側面には落下事故防止用の背当枠４（第２
図参照）を、更にまた、第２図示の如く休憩装置２４を

に対称的に配向した状態で、締付用ボルト７を通してナ
ツトにより一体的に締付は固定する。When attaching the step 20 configured as described above to the liner plate 6, as shown in FIG. Position the fixing piece 3 and tighten the flange 6.
The steps installed on the upper side of a are oriented upward, while the steps installed on the lower side are oriented downward, that is, symmetrically vertically with respect to the flange 6a, and are integrally tightened with a nut through the tightening bolt 7. is fixed.
このようにして、ライナプレート用６の継手ボルト７を
利用してその内側に複数の踏段具２０を縦列状に取付は
固定して昇降タラップを構成する。In this way, a plurality of steps 20 are attached and fixed in a column inside the joint bolt 7 of the liner plate 6, thereby constructing an elevating ramp.
踏段具の取付は固定は、ボルト・ナツトによる取付けと
したので取付は取外しが可能となり、現場移動の際等に
は分解運搬が容易となる。Since the steps are fixed using bolts and nuts, they can be removed and disassembled easily when moving to the site.
第３図及び第４図は休憩装置２４の一実施例を示すもの
で、８は支持体、９は休憩用開閉板である。FIGS. 3 and 4 show an embodiment of the resting device 24, in which 8 is a support and 9 is an opening/closing plate for resting.
該支持枠体８は湾曲状に形成され、その基端側８ａには
上下に差込ピン１０が固着されていて、上記受金具５に
差込んで取付けられるようになっている。The support frame 8 is formed into a curved shape, and insertion pins 10 are fixed to the upper and lower sides of the base end 8a, so that the support frame 8 can be inserted into and attached to the receiving fitting 5.
そのため、この休憩装置２４は、第２図示の如く、ライ
ナプレート用６のフランジ６ａのピッチの半分のピッチ
で、上下配設位置の移動が可能となる。Therefore, this resting device 24 can be moved up and down at a pitch that is half the pitch of the flanges 6a of the liner plate 6, as shown in the second figure.
該支持枠体８の上端面は略水平に形成されていて、その
上に休憩用開閉板９が乗載されている。The upper end surface of the support frame 8 is formed substantially horizontally, and a break opening/closing plate 9 is mounted on it.
該開閉板９は金網でも鉄板でも良い。The opening/closing plate 9 may be a wire mesh or an iron plate.
該開閉板９は蝶番１１により上記支持枠体８に開閉自在
に取付けられている。The opening/closing plate 9 is attached to the support frame 8 by a hinge 11 so as to be openable and closable.
上記のように構成された休憩装置２４を前記昇降タラッ

所望位置の踏段の受金具５に支持枠体８に付設した上側
の差込ピン１０を差込み、同時に下側の差込ピン１０を
１段下側の踏段の受金具５に差込んで、該支持枠体８を
確実に固定する。In order to arrange the break device 24 configured as described above in the middle of the elevator ramp, as is clear from FIG. The support frame 8 is securely fixed by inserting the insertion pin 10 and simultaneously inserting the lower insertion pin 10 into the receiving metal fitting 5 of the step one step below.
従って、ステップを下降するに際しては、上記開閉板９

も良い。Therefore, when descending the step, the opening/closing plate 9
After taking a break at the top, put your feet back on the treadle 1, grab the upper treadle 1 with one hand, bend down with your body resting on the step, and use your free hand to open and close the opening/closing plate 9. As shown by the imaginary line in Figure 4, open it upwards so that it can pass through, or hook the tip of the opening/closing plate 9 with the top of one foot and lift it up a little to open it, or use some other assistance to open it. You may use tools.
逆に、ステップを上昇するに際しては、開閉板９を下側
から単に押し上げれば、開閉板９はそのまま開いて通過
出来る。Conversely, when going up the step, simply pushing up the opening/closing plate 9 from below allows the opening/closing plate 9 to open and pass through.
尚、第２図において１２は親綱であってロリング１３を
介して身体を連結し、ステップ踏外しによる落下事故等
を防止するようになっている。In FIG. 2, reference numeral 12 denotes a main rope, which connects the body through a rolling ring 13 to prevent accidents such as falling due to missing a step.
以上説明した如くこの考案は構成されているので以下の
効果を得る。Since this invention is configured as explained above, the following effects can be obtained.
この踏段具は、単一形状でありながら、取付時に反転す

せることができ、簡略な構成となり、製作および組付・
取扱が容易となり、また踏段のピッチを安全な距離とし
得る著効を有する。Although this step has a single shape, it can function as an upper and a lower step by simply inverting it when installed, resulting in a simple configuration and easy manufacturing and assembly.
It is easy to handle and has the remarkable effect of keeping the pitch of the steps at a safe distance.
また、受金具は各踏段具に固定されているので、背当枠
や休憩装置などの機器の取付位置を小刻みに移動変更し
得る。Further, since the receiving metal fittings are fixed to each step, the mounting position of devices such as the back support frame and the rest device can be moved and changed in small increments.
更に、側杆は斜め前方に張出し、懐部を形成するので、
この空間部に突出することのある工事用器具を効果的に
回避し得るし、昇降時の足掛けも安全確実なものとなる
。Furthermore, the side rods extend diagonally forward and form a pocket, so
Construction tools that may protrude into this space can be effectively avoided, and footrests when going up and down can be made safe and secure.
