Description

【０００１】
【発明の属する技術分野】
本発明は、部材接続装置に係り、例えば隣り合うコンクリート製品等の接続に使用される接続装置に関するものである。
【０００２】
【従来の技術】
例えば、重量がかなり重く、一つ一つのユニットの重量が何トンもあるコンクリート製Ｕ字溝あるいはコンクリート製ヒューム管等を長手方向に接続して敷設する場合、従来では該コンクリート製品の接続作業がきわめて面倒で困難な作業となっていた。
【０００３】
すなわち、従来この種の接続作業は、接続すべきコンクリート製品をクレーンで吊り上げ、接続すべき位置まで移送する。
しかし、正確に接続すべき位置まで移送できないため、正確な位置あわせ、最終の接続微調整は、接続すべきコンクリート製品の端部を何人もの作業者でバール等を用いて接続側へ押すことにより行っていた。
【０００４】
また、接続後に、何らかの理由により一旦最終接続した部材を離脱させたいときに、簡単に接続切り離しが出来る用途をも有する接続装置は提供されてはいなかった。
【０００５】
【発明が解決しようとする課題】
しかしながら、従来のような接続作業はかなりの労力と作業手間、作業コストがかかり、効率的ではない。また、接続後に何らかの理由により一旦最終接続した部材を離脱させたいとき、簡単に接続切り離しが出来る用途をも有する接続装置の提供は現場での要請がきわめて多いものであった。
【０００６】
かくして、本発明は前記従来の課題に対処すべく創案されたものであり、接続すべきコンクリート製品の接続微調整、あるいは接続のための正確な位置あわせが簡単に行え、しかも製品コストがきわめて安価な部材の接続装置を提供することを目的とするものである。
また、接続後に何らかの理由により一旦接続した部材を離脱させたいときに、該接続装置を兼用して簡単に接続切り離しが出来る接続装置を提供することを目的とするものである。
【０００７】
【課題を解決するための手段】
本発明による部材の接続方法は、
相隣る接続すべき部材の対向する接続面近傍の側面に各々穴を設け、
前記双方の穴に差し込み部材を差し込み、
差し込んだ一方側の差し込み部材には係止部を係止させ、他方側の差し込み部材には係止溝を嵌め込み直前状態にして接続板を配置して、該接続板を双方の差し込み部材間に仮架設し、
前記仮架設した接続板に続いて、
一端側は一方側の差し込み部材に係止する係止部を有し、他端側は作動板の一端を回動可能に軸支した軸支部を有する治具本体と、一端が軸支部により治具本体の他端と回動可能に軸支され、他端側には前記他方側の差し込み部材に掛合可能な掛合凹部を有する作動板と、該作動板に取り付けられた操作棒とを有する接続治具を双方の差し込み部材間に取り付け、
前記他方側の差し込み部材に掛合させた掛合凹部を回転軸として前記操作棒を回動し接続すべき相隣る部材を引き寄せて、前記接続板の嵌め込み直前状態をなす係止溝内に他方側の差し込み部材を嵌め込み、相隣る接続すべき部材を接続することを特徴とするものである。
【０００８】
【発明の実施の形態】
以下、図に基づいて本発明に係る部材の接続装置の一実施例について説明する。
図において、符号１は接続すべきコンクリート製品を示す。
かかるコンクリート製品１を複数個接続して一般に下水道、上水道の暗渠あるいはＵ字溝等が形成される。
【０００９】
ここで、コンクリート製品１は重量が重く、その一つ一つそれ自体で何トンもの重量を有している。
したがって、これらコンクリート製品１の接続作業、特に接続微調整はきわめて面倒で困難な作業となる。
まず、接続すべきコンクリート製品１をクレーン等で吊り上げ、接続すべき設置箇所まで移送する。
【００１０】
ここで、コンクリート製品１にはあらかじめ、その長手方向両端の上方位置でかつ両脇に吊り上げ用の穴４が都合４カ所に穿設されている。
従ってこの４カ所の穴４に棒状の差し込み部材５を嵌め込み、これをフックとして使用してクレーン等で吊り上げ、所定の設置個所まで移動するのである。
設置個所まで移動した後、吊り上げてあるコンクリート製品１を降下させ、既に設置してあるコンクリート製品１の接続面２と吊り上げてあるコンクリート製品１の接続面２とを対向させつつ設置すべきコンクリート製品１を仮置きする。
【００１１】
尚、前述したとおり、相隣るコンクリート製品１，１の対向する接続面２，２近傍の側面３，３には各々穴４，４が穿設されており、該穴４，４にはクレーン等で吊り上げるために使用するフック用の差し込み部材５，５が差し込まれているが、この差し込み部材５，５をコンクリート製品１，１の接続作業にも使用することになる。
【００１２】
まず、差し込み部材５，５間に亘ってまず接続板６を仮架設する。
接続板６は図６から理解されるように、略方形状をなし、両端側に各々凹溝状をなす係止部７と係止溝８とを有するタイプと図７から理解されるように、一端側には透孔として形成された係止部７と他端側には凹溝状をなす係止溝８とを有するタイプとがある。尚、図には両タイプを具体例として示したが、何らこれに限定されるものではない。
【００１３】
図６に示す接続板６を両差し込み部材５，５間に仮架設するのは、図３に示すように、一方側の差し込み部材５に凹溝条の係止部７を嵌め込み、他方側の差し込み部材５上には他方側の係止溝８近傍の接続板下面を載置させて仮架設する。これにより、他方側の差し込み部材５には接続板６の他方側の係止溝８が嵌め込み直前状態とされる。
【００１４】
また、図７に示す接続板６については、一方側の差し込み部材５を一旦抜き、接続板６の透孔状係止部７に差し込みながら穴４に差し込み、他方側の差し込み部材５上にはやはり他方側の係止溝８近傍の接続板下面を載置させて嵌め込み直前状態として仮架設しておくものとする。
その後、接続治具９を前記接続板６に続いて両差し込み部材５，５間に取り付ける。
【００１５】
ここで、接続治具９の構成につき説明する。該接続治具９は治具本体１０と作動板１１と操作棒１２とを有して構成されている。
治具本体１０は略長方形状をなし、その長手方向の一端側には一方側に位置する差し込み部材５に係止する凹溝状の係止部１３が形成され、他端側には接続すべき作動板１１の一端を回動可能に軸支した軸支部１４が形成されている。
【００１６】
しかし、この治具本体１０の形状等も略長方形状のみに限定されるものではない。
そして、作動板１１は図示するように、正方形に近い長方形状をなし、その長手方向一端側は前記治具本体１０の他端と回転可能に軸支され、他端側には長手方向一端側に向かって切欠された掛合凹部１５が形成されている。
【００１７】
尚、この作動板１１の形状についても何らこの実施の態様に限定されるものではない。
次に符号１２は操作棒であり、図５に示すように作動板１１の一側面側に取り付けられている。
以上において接続治具９の取付状態につき説明する。
【００１８】
まず、図５に示すように、治具本体１０の凹溝状をなす係止部１３内に一方側に位置する差し込み部材５を嵌め込んで係止させる。次いで作動板１１の他端に形成された掛合凹部１５内に他方の差し込み部材５を入れ、その状態から操作棒１２を図に向かって右側に回転させる。
すると、作動板１１は掛合凹部１５と他方の差し込み部材５との掛合部を回転軸として回転し、その結果治具本体１０は他方側の差し込み部材５側に引っ張られる。そしてこれにより相隣るコンクリート製品１，１の接続面２，２間は図５の状態から図１の状態になり、図１の状態になったとき、他方の差し込み部材５上で嵌め込み直前状態とされていた接続板６の係止溝８内に他方の差し込み部材５が嵌まり込み、その結果コンクリート製品１，１は正確、確実に接続される。
【００１９】
ところで、相隣るコンクリート製品１，１の接続面２，２間には柔軟性を有するパッキング材１６，１６が介在されており、これが接続の際、押圧されてより密着された接続が得られる。
図３のように接続板６で両コンクリート製品１，１を完全に繋いだ後、接続治具９を外して接続作業は終了する。
【００２０】
ここで、一対の差し込み部材５，５と接続板６はいわゆる埋め殺し部材となるが、接続治具９は汎用部材として何回も使用できる。
尚、何らかの事情で一度接続したコンクリート製品１，１の接続を解かなくてはならない場合、本発明では簡単にその接続離脱が出来、これが本発明の大きな特徴となっている。
【００２１】
すなわち、図３の状態から図１に示す状態に接続治具９を設置し、図１の矢印の方向に向かって操作棒１２を若干回転させる。すると接続板６の係止部７，係止溝８と一対の差し込み部材５，５との嵌め込み関係が若干緩み、その状態で接続板６を上方に持ち上げれば、簡単に接続板６が外れるものとなる。
しかして、このような本発明の構成によれば、操作棒１２を回転させるという小さな力のみで迅速に、確実かつ正確に位置決めして相隣るコンクリート製品１，１を接続できるものとなり、またこの強固な接続を同じ装置を使用して簡単に外すことが出来る。
【００２２】
しかも、接続に使用する穴４は吊り上げ移動で使用する吊り上げ穴を利用して兼用するものであり、その面からも作業の軽減が図れる。
【００２３】
【発明の効果】
かくして本発明は以上の構成よりなる。
そして、本発明による部材の接続装置であれば、接続すべきコンクリート製品の接続微調整、あるいは確実、正確な位置あわせが簡単に行え、しかも製品コストがきわめて安価な部材の接続装置が提供できる。
【００２４】
さらにこの強固な接続を同じ装置を使用して簡単に外すことが出来る。
しかも、接続に使用する穴は吊り上げ移動で使用する吊り上げ穴を利用して兼用するものであり、その面からも作業の軽減が図れる。

[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of a member connecting device according to the present invention will be described with reference to the drawings.
In the figure, reference numeral 1 denotes a concrete product to be connected.
A plurality of such concrete products 1 are generally connected to form a sewer, a culvert of a water supply, a U-shaped groove, or the like.
[0009]
Here, the concrete product 1 is heavy, and each of them has a weight of several tons.
Therefore, the connection work of these concrete products 1, especially the connection fine adjustment, is extremely troublesome and difficult.
First, the concrete product 1 to be connected is lifted by a crane or the like and transferred to an installation location to be connected.
[0010]
Here, the concrete product 1 is previously provided with four lifting holes 4 at upper positions on both sides in the longitudinal direction and on both sides.
Therefore, rod-like insertion members 5 are fitted into the four holes 4 and are used as hooks to be lifted by a crane or the like and moved to a predetermined installation location.
After moving to the installation site, the suspended concrete product 1 is lowered, and the concrete product to be installed while facing the connection surface 2 of the already installed concrete product 1 and the connection surface 2 of the concrete product 1 being lifted. Place 1 temporarily.
[0011]
As described above, holes 4 and 4 are formed in side surfaces 3 and 3 in the vicinity of opposing connecting surfaces 2 and 2 of adjacent concrete products 1 and 1, respectively. Insertion members 5 and 5 for hooks that are used for lifting with the like are inserted, but the insertion members 5 and 5 are also used for connecting the concrete products 1 and 1.
[0012]
First, the connecting plate 6 is temporarily installed between the insertion members 5 and 5.
As can be understood from FIG. 6, the connecting plate 6 has a substantially rectangular shape, and has a locking portion 7 and a locking groove 8 each having a concave groove shape on both ends, as can be understood from FIG. 7. There is a type having a locking portion 7 formed as a through hole on one end side and a locking groove 8 having a concave groove shape on the other end side. In addition, although both types were shown as an example in the figure, it is not limited to this at all.
[0013]
As shown in FIG. 3, the connecting plate 6 shown in FIG. 6 is temporarily installed between the insertion members 5 and 5 by inserting the engaging portion 7 of the concave groove into the insertion member 5 on one side and the other side. On the insertion member 5, the lower surface of the connection plate in the vicinity of the other locking groove 8 is placed and temporarily installed. As a result, the engagement groove 8 on the other side of the connection plate 6 is brought into a state just before fitting into the insertion member 5 on the other side.
[0014]
For the connection plate 6 shown in FIG. 7, the insertion member 5 on one side is temporarily pulled out and inserted into the hole 4 while being inserted into the through-hole-shaped locking portion 7 of the connection plate 6. It is assumed that the lower surface of the connecting plate in the vicinity of the other locking groove 8 is also placed and temporarily installed as a state immediately before fitting.
Thereafter, the connecting jig 9 is attached between the insertion members 5 and 5 following the connecting plate 6.
[0015]
Here, the configuration of the connection jig 9 will be described. The connecting jig 9 includes a jig main body 10, an operation plate 11, and an operation rod 12.
The jig body 10 has a substantially rectangular shape, and is formed with a concave groove-like locking portion 13 for locking with the insertion member 5 located on one side at one end side in the longitudinal direction and connected to the other end side. A shaft support portion 14 that pivotally supports one end of the power actuating plate 11 is formed.
[0016]
However, the shape of the jig body 10 is not limited to a substantially rectangular shape.
As shown in the figure, the operation plate 11 has a rectangular shape close to a square, and one end in the longitudinal direction thereof is rotatably supported by the other end of the jig body 10, and one end in the longitudinal direction is supported at the other end. An engaging recess 15 is formed that is cut away toward the front.
[0017]
The shape of the operating plate 11 is not limited to this embodiment.
Next, reference numeral 12 denotes an operating rod, which is attached to one side of the operation plate 11 as shown in FIG.
The mounting state of the connection jig 9 will be described above.
[0018]
First, as shown in FIG. 5, the insertion member 5 located on one side is fitted into the locking portion 13 having a concave groove shape of the jig body 10 to be locked. Next, the other insertion member 5 is placed in the engaging recess 15 formed at the other end of the operating plate 11, and the operating rod 12 is rotated to the right as viewed from the state.
Then, the operation plate 11 rotates with the engagement portion between the engagement recess 15 and the other insertion member 5 as a rotation shaft, and as a result, the jig body 10 is pulled toward the other insertion member 5 side. As a result, the space between the connection surfaces 2 and 2 of the adjacent concrete products 1 and 1 is changed from the state of FIG. 5 to the state of FIG. 1, and when the state of FIG. The other insertion member 5 fits into the locking groove 8 of the connecting plate 6 that has been assumed to be connected, and as a result, the concrete products 1 and 1 are connected accurately and reliably.
[0019]
By the way, the flexible packing materials 16 and 16 are interposed between the connection surfaces 2 and 2 of the adjacent concrete products 1 and 1, and when this is connected, the connection is pressed and a tighter connection is obtained. .
After connecting both the concrete products 1 and 1 completely with the connecting plate 6 as shown in FIG. 3, the connecting jig 9 is removed and the connecting operation is completed.
[0020]
Here, the pair of insertion members 5 and 5 and the connection plate 6 are so-called burying members, but the connection jig 9 can be used many times as a general-purpose member.
In addition, when it is necessary to break the connection of the concrete products 1 and 1 once connected for some reason, the connection can be easily disconnected in the present invention, which is a major feature of the present invention.
[0021]
That is, the connecting jig 9 is installed from the state shown in FIG. 3 to the state shown in FIG. 1, and the operation rod 12 is slightly rotated in the direction of the arrow in FIG. Then, the fitting relationship between the locking portion 7 and the locking groove 8 of the connection plate 6 and the pair of insertion members 5 and 5 is slightly loosened. If the connection plate 6 is lifted upward in this state, the connection plate 6 is easily detached. It will be a thing.
Thus, according to the configuration of the present invention, the adjacent concrete products 1 and 1 can be connected quickly and reliably and accurately with only a small force of rotating the operation rod 12, and This strong connection can be easily removed using the same device.
[0022]
In addition, the holes 4 used for connection are also used by using the lifting holes used for the lifting movement, and the work can be reduced also from the surface.
[0023]
【The invention's effect】
Thus, the present invention has the above configuration.
With the member connecting device according to the present invention, it is possible to provide a member connecting device that can easily finely adjust the connection of a concrete product to be connected, or that can be reliably and accurately positioned, and at a very low product cost.
[0024]
Furthermore, this strong connection can be easily removed using the same device.
In addition, the holes used for the connection are also used by using the lifting holes used for the lifting movement, and the work can be reduced also from the surface.
