Description
【0001】[0001]
本考案は、屋外建設現場等の軟弱、起伏のある地盤に敷並べられ、パワーショ ベルや大型クレーン車等の重機がその上で移動走行する敷鉄板を多数連結する際 に用いられる敷鉄板の連結具に関するものである。 INDUSTRIAL APPLICABILITY The present invention is used to connect a large number of flat iron plates that are laid out on a soft, undulating ground such as an outdoor construction site and used by heavy equipment such as power shovels and large crane trucks to move and run on them. It is about ingredients.
【0002】[0002]
従来、屋外建設現場等における作業用車両の出入口付近では、種々の作業車両 が頻繁に出入りし、特に大型ダンプ、パワーショベルあるいは大型クレーン車等 の重機が作業を行う場合も考慮し、又、雨天時のぬかるみの対処といった作業環 境の改善や作業の効率性の点、更に、高層ビル等の基礎工事の場合等のように大 掛かりな掘削工事を伴う場合その掘削開口端の近傍では重機を使用する関係から もより確固とした足場が要求され、足場崩れ等の事故を防止する目的からも敷鉄 板を適宜な場所に敷き並べて路盤の補強を図っていた。そして、上記のように補 強のために用いられる一般的な敷鉄板は、その上で重機等が激しく動いた場合で もむやみに移動したりすることがないように大型のサイズで厚みが1〜3cm、 重さが一枚につき1〜2トンもあるような鉄板が用いられ、現場内の所定の場所 一面にわたって敷き並べ、隣合う敷鉄板にフラットバーを掛け渡し、溶接によっ て両者を接続していた。しかしながら、このように溶接してしまった場合には、 敷鉄板を他の場所に移設させる際、再度、フラットバーを溶断しなければならず 、手間が掛り、又、このように溶接して用いた場合にはリース会社等への返納時 に補修費が掛っていた。更には敷鉄板の路盤への固定措置を何ら講じてはいない ために、重機等が激しく移動動作を繰り返す場合にはこの厚くて重い敷鉄板さえ も、簡単に移動してしまうことがあった。 Conventionally, various work vehicles frequently come and go near the entrances and exits of work vehicles at outdoor construction sites, especially when heavy equipment such as large dump trucks, excavators, or large crane trucks work, and in rainy weather. Improvement of work environment such as dealing with muddy time, work efficiency, and large-scale excavation work such as foundation work for high-rise buildings, etc. A more solid scaffolding is required due to the usage relationship, and for the purpose of preventing accidents such as collapse of the scaffolding, iron sheets were laid in appropriate places to reinforce the roadbed. And, as mentioned above, the general laid iron plate used for reinforcement has a large size and a thickness of 1 so that it does not move unnecessarily even when heavy machinery etc. moves violently on it. ~ 3 cm, weight of 1 to 2 tons per sheet is used, and iron sheets are laid out over a specified place on the site, and a flat bar is laid between adjacent iron sheets, and both are welded together. I was connected. However, if the welding is done in this way, the flat bar must be melted again when the flat iron plate is relocated to another location, which is time-consuming and requires welding in this way. In that case, repair costs were incurred when returning to a leasing company. Furthermore, since no measures were taken to secure the iron plate to the roadbed, even when the heavy equipment repeatedly moved violently, even this thick and heavy iron plate could easily move.
【0003】[0003]
このように、重機等の動作等によって敷鉄板が移動してしまった場合には、再 度敷き並べなければならなかったが、前述したように一枚1〜2トンもある重量 物であるために人力では簡単に行えず、やむをえず、パワーショベル等のバケッ トのツメ等によって引っ掛けるようにして行うこともあり、しかも重機以外に作 業員を要し、作業中に足や指を挟んだりといった作業上の危険も伴うといった問 題点も有った。又、フラットバーで溶接してある場合には前述したように更に移 設作業が煩雑となる等の課題を有していた。 In this way, when the iron plate was moved due to the operation of heavy equipment, etc., it was necessary to lay it again, but since it is a heavy item with one to two tons as described above. It can not be easily done manually, and it is unavoidable that it is hung by the claws of a bucket such as a power shovel.In addition, it requires an operator other than heavy equipment, and it may be necessary to pinch your feet or fingers during work. There was also a problem that there was a work-related risk. Further, when welding is performed by using a flat bar, there is a problem that the transfer work is further complicated as described above.

本考案は前述したような問題点を解決するために成されたものであり、その目 的は、工事現場等の軟弱地盤上に地盤補強材として複数枚隣接して敷並べられ、 周縁に所定の間隔で穴部が形成されてなる敷鉄板を、前記穴部の地盤に突き刺し て連結するための連結具であって、対応する前記穴部間を跨着可能に「コ」の字 状に構成すると共に両足部側を「く」の字状に形成した屈曲部を有した構成とす る。 The present invention was made in order to solve the above-mentioned problems. The purpose of the present invention is to lay a plurality of adjacent ground reinforcements on soft ground such as a construction site, and set them at the periphery. A connecting tool for piercing and laying a laid iron plate in which holes are formed at intervals of, into the ground of the holes, in a U-shape so that the corresponding holes can be straddled. In addition to the above configuration, both legs have a bent portion formed in a V shape.
【0005】 又、前記屈曲部の挟角度を110度と設計することが望ましい。Further, it is desirable to design the included angle of the bent portion to be 110 degrees.
【0006】[0006]
上記のような構成であるので、敷鉄板の敷設に際しては、穴部が対向一致する ように敷鉄板を現場に応じて所定枚数配置し、隣接する穴部に対して連結具の足 部側の屈曲部を回し込むように打ち込んで地盤に固着させるものである。 以上のように、連結具の両足部側を両方の敷鉄板の穴部に跨がるように打ち込 み固定するのであるが、連結具の地盤に差し込まれる足部側に屈曲部が形成され ているので地盤中で「く」の字状となり、敷鉄板ごと連結具を上方に引き抜こう とする外力に対しても充分に対抗でき、しかも同様にして地盤に固着された多数 の敷鉄板は相互に連結された状態となり、所謂「相持ち」となる結果、外力への 対抗力が相乗的に高まることになる。その結果、敷鉄板上で重機等が激しく動い ても、位置ずれが起きることはない。そして、従来の如く溶接作業等も要しない ところから作業も迅速に行なえ、補修費も不要であるところからコストも安価で ある。 With the above configuration, when laying an iron laying plate, a certain number of iron laying plates are arranged according to the site so that the holes are facing each other, and the foot side of the connecting device is attached to the adjacent holes. The bending part is driven in like a turn and is fixed to the ground. As described above, the two foot parts of the connecting tool are struck and fixed so as to straddle the holes of both laying iron plates, but the bent part is formed on the foot part side of the connecting tool to be inserted into the ground. Since it has a V shape in the ground, it can sufficiently counteract the external force that pulls out the connecting tool together with the iron plate, and in the same way, the many iron plates fixed to the ground are As a result of being connected to each other and becoming a so-called “coherence”, the counter force against external force is synergistically increased. As a result, even if heavy machinery moves violently on the iron plate, the position will not be displaced. Moreover, the work can be done quickly because welding work is not required as in the past, and the cost is low because no repair cost is required.
【0007】 又、前記屈曲部の挟角度を110度に設計することによって打ち込み作業もさ ほど困難ではなく、又、移設の際の引抜作業もバール等を使って容易に行なうこ とができるものである。By designing the angle of the bent portion to be 110 degrees, the driving work is not so difficult, and the pulling work at the time of relocation can be easily performed by using a burl or the like. Is.

以下、図1乃至図3に基づいて本考案に係る敷鉄板の連結具の一実施例を詳細 に説明する。 図1は連結具を用いて隣合う敷鉄板どうしを連結する状態を示した斜視図、図 2は連結状態を示す全体平面図、図3は図2のF−F線視断面図である。 Hereinafter, one embodiment of a laying iron plate connector according to the present invention will be described in detail with reference to FIGS. 1 to 3. FIG. 1 is a perspective view showing a state where adjacent iron sheet plates are connected using a connecting tool, FIG. 2 is an overall plan view showing a connected state, and FIG. 3 is a sectional view taken along line FF of FIG.
【0009】 1は軟弱な地盤G等に補強用に複数枚敷設される敷鉄板であり、端部のコーナ ーや端部中央には貫通する穴2…が夫々設けられている。 3は前記穴2、2どうしを連結する連結ピンであり、頭部2aは対応する穴2 、2間を跨着可能に「コ」の字状に構成し、両足部2bの先端側を「く」の字状 に形成(好ましい例としては挟角度を図3に示す如く約110度に形成)した屈 曲部2cを有した構成とするものである。Reference numeral 1 denotes a laid iron plate which is laid on the soft ground G or the like for reinforcement, and has corners at the ends and holes 2 penetrating at the center of the ends. Reference numeral 3 denotes a connecting pin that connects the holes 2 and 2, the head 2a is formed in a "U" shape so as to be able to straddle between the corresponding holes 2 and 2, and the tip ends of both the foot portions 2b are ". The bent portion 2c is formed in a V shape (preferably, the sandwiching angle is formed to be about 110 degrees as shown in FIG. 3).
【0010】 尚、両足部2bは敷鉄板1を敷設する地盤の状態(土質の硬軟等)に適応した 長さのものを用いるものである。 尚、この連結ピン3の頭部3aの断面形状はやや偏平としてつまづきを防止す る形状としているものである。(図3参照) 以下、上記の構成に基づいて本考案に係る敷鉄板の使用態様を説明する。The both legs 2b have a length suitable for the state of the ground on which the iron plate 1 is laid (hardness of soil, etc.). The cross-sectional shape of the head 3a of the connecting pin 3 is slightly flat so as to prevent tripping. (Refer to FIG. 3) Hereinafter, based on the above-mentioned structure, a usage mode of the iron plate according to the present invention will be described.
【0011】 即ち、敷設する地盤G上に敷鉄板1、1…を隣合うように複数枚配置し、それ ぞれの周縁に形成された穴2、2が対向するように位置合わせを行い、両穴2間 を跨ぐように連結ピン3の足部3bを差し込み、頭部3aをハンマー等を用いて 打ち込むのであるが、この際、屈曲部3cが地盤Gに強固に食い込み、敷鉄板1 、1…どうしが相互に連結され固着して敷設作業を行うものである。That is, a plurality of laid iron plates 1, 1, ... Are arranged adjacent to each other on the ground G to be laid, and alignment is performed so that holes 2 and 2 formed on the periphery of each of them are opposed to each other. The foot portion 3b of the connecting pin 3 is inserted so as to straddle between the holes 2, and the head portion 3a is driven by using a hammer or the like. At this time, the bent portion 3c firmly bites into the ground G, and the iron plate 1, 1 ... Laying work is performed by connecting and fixing each other.
【0012】 このように、一枚につき1〜2トンもある敷鉄板1どうしを連結ピン3を用い て連結しかつ、地盤Gに所定の深さ(地盤の状況に応じた足部3bの長さの連結 ピン3を用いるものである)に打ち込むことによって、敷鉄板1はそれぞれが所 謂「相持ち」の状態となり、例え、敷鉄板1上でパワーショベルやクレーン車等 の重機が激しい動きを伴う作業を行った場合でも移動してしまうことはない。又 、図3に示すように連結状態で連結ピン3の頭部3aは偏平に構成されているの でつまずくといった支障は起きない。As described above, the laid iron plates 1 each having 1 to 2 tons are connected to each other using the connecting pins 3, and the ground G has a predetermined depth (the length of the foot portion 3b depending on the condition of the ground). The iron laying plate 1 is in a so-called “coincidental” state by driving into each other (for example, using a connecting pin 3), and for example, heavy machinery such as a power shovel or a crane truck moves violently on the laying iron plate 1. It does not move even when performing work involving. Further, as shown in FIG. 3, since the head 3a of the connecting pin 3 is flat in the connected state, no trouble such as tripping occurs.
【0013】 以上のように本考案においては、相当の重量の敷鉄板1を複数枚連結し、しか も各端部を充分な長さの足部3bでもって確固と地盤Gに打ち込んでなるので、 重機等がかなり激しい運動を行なっても連結ピン3を外さない限り敷鉄板1が移 動してしまうことはない。 又、各敷鉄板1…は強固に連結されているものの、穴2と連結ピン3との間に は適切なクリアランスCが確保されるのでバール等の所定の道具を用いれば連結 ピン3を意図的に外す作業は迅速かつ簡単に行うことができ、作業工程に伴う敷 鉄板1の配置換えも比較的スムースに行うことができる。As described above, in the present invention, a plurality of laid iron plates 1 having a considerable weight are connected, and each end is firmly driven into the ground G with the foot portions 3b having a sufficient length. , Even if heavy machinery or the like makes a considerable amount of exercise, the iron plate 1 will not move unless the connecting pin 3 is removed. Further, although each iron plate 1 ... Is firmly connected, an appropriate clearance C is secured between the hole 2 and the connecting pin 3, so the connecting pin 3 is intended if a predetermined tool such as a burl is used. The removal work can be performed quickly and easily, and the layout of the iron plate 1 associated with the work process can be changed relatively smoothly.
