以下、本発明の実施例を図に基づいて説明する。
図1乃至図5に本発明による床版取り替え装置1のいわゆる高速道路の路面上などの工事現場での設置工法の手順を示す。
Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 to FIG. 5 show the procedure of the installation method at a construction site such as a so-called expressway surface of the floor slab replacement apparatus 1 according to the present invention.

ここで、まず、床版取り替え装置1の概略構成を説明すると、符号2は上部枠を示し、該上部枠は、水平方向に向って配置された略四角形枠体をなして構成されている。そして、この上部枠2の四隅コーナー部からは、各々垂下して取り付けられた4本の主脚3および4本の斜脚4が設けられている。
また、前記上部枠2の内側部分には、床版吊り具5が取り付けられるものとなっている。
Here, first, a schematic configuration of the floor slab replacement apparatus 1 will be described. Reference numeral 2 denotes an upper frame, and the upper frame is configured to form a substantially rectangular frame arranged in the horizontal direction. From the four corners of the upper frame 2, there are provided four main legs 3 and four oblique legs 4 which are respectively attached in a suspended manner.
A floor stool 5 is attached to the inner portion of the upper frame 2.

さらに、上部枠2から、該上部枠2の幅方向外側に向かい水平方向に引き出し可能とされてなる引き出し部6が設けられている。よって、4本の主脚3の先端側からは、おのおの4本の引き出し部6が幅方向水平方向に引き出される構成となる。   Further, a drawer portion 6 is provided that can be pulled out from the upper frame 2 in the horizontal direction toward the outside in the width direction of the upper frame 2. Therefore, each of the four drawer portions 6 is pulled out in the horizontal direction in the width direction from the distal end side of the four main legs 3.

さらに、前記引き出し部6の引き出し後は、その引き出し部6の先端部から垂下方向に伸張し、例えば高速道路の路面などの設置面13上に当接する垂下伸張部7を有しており、この垂下伸張部7の伸張により、床版取り替え装置1自体を保持すべく、床版取り替え装置1自体を後述する車両8の荷台9から浮かせられる構成とされている。この垂下伸張部7も4本設けられるものとなる。   Further, after the drawer portion 6 is pulled out, it has a drooping extension portion 7 that extends in the hanging direction from the tip portion of the drawing portion 6 and abuts on an installation surface 13 such as a road surface of an expressway. In order to hold the floor slab replacement apparatus 1 itself, the floor slab replacement apparatus 1 itself is lifted from the loading platform 9 of the vehicle 8 to be described later by the extension of the drooping extension section 7. Four drooping extensions 7 are also provided.

よって、本発明の床版取り替え装置1は、自力で車両8の荷台9に乗り込ませて載置させることが出来るし、車両8の荷台9などに載置してこの床版取り替え装置1を運搬した後、自力で、すなわち床版取り替え装置1が自ら有する部材の構造で高速道路の路面上などの設置面13に設置、架設することが出来るのである。   Therefore, the floor slab replacement apparatus 1 of the present invention can be placed on the loading platform 9 of the vehicle 8 by itself and placed on the loading platform 9 of the vehicle 8 to carry the floor slab replacement apparatus 1. After that, it can be installed and installed on the installation surface 13 such as on the road surface of the expressway by itself, that is, the structure of the member that the floor slab replacement device 1 has.

ここで、前記斜脚4については前記上部枠2との連結部10を回動軸として回動出来るようにしてあり、斜脚4を回動させた後、斜脚4の先端側11が垂下伸張部7の先端側12に接続して取り付け、もって、斜脚4を、主脚3の補強材として機能させている。   Here, the oblique leg 4 can be rotated about the connecting portion 10 with the upper frame 2 as a rotation axis. After the oblique leg 4 is rotated, the distal end side 11 of the oblique leg 4 is suspended. The inclined leg 4 is made to function as a reinforcing material for the main leg 3 by connecting and attaching to the distal end side 12 of the extending portion 7.

図1は、車両8の荷台に載置して本発明による床版取り替え装置1を高速道路の路面上など工事現場に運搬する状態を示した図であり、図2乃至図5は床版取り替え装置1を、床版取り替え装置1が自ら有している構造によって自力で車両8の荷台9から降ろすことが出来、かつ自力で高速道路の路面上に設置できる工程を示したものである。   FIG. 1 is a view showing a state in which a floor slab replacement apparatus 1 according to the present invention is placed on a loading platform of a vehicle 8 and transported to a construction site such as on a road surface of an expressway, and FIGS. The apparatus 1 can be lowered by itself from the loading platform 9 of the vehicle 8 by the structure of the floor slab replacement apparatus 1 and can be installed on the road surface of the expressway by itself.

まず、図2に示してあるように、上部枠2の幅方向先端から上部枠2の幅方向外側に向かい水平方向に引き出せる引き出し部6を上部枠2の四隅部4箇所から所定長さ引き出すことにより始まる。   First, as shown in FIG. 2, the drawer portion 6 that can be pulled out horizontally from the width direction front end of the upper frame 2 toward the outside in the width direction of the upper frame 2 is pulled out from the four corners of the upper frame 2 to a predetermined length. Begins with.

次いで、前記引き出し部6の引き出し後は、その引き出し部6の先端部から4本の垂下伸張部7をおのおの垂下方向に伸張させ、設置面13上に当接させる。   Next, after the drawer portion 6 is pulled out, the four hanging extension portions 7 are extended from the leading end portion of the drawing portion 6 in the hanging direction and brought into contact with the installation surface 13.

この垂下伸張部7の伸張により、床版取り替え装置1自体の重量を自力で保持することとなり、床版取り替え装置1自体を車両8の荷台9から浮かせることができる。
そして、図3に示すように、斜脚4の先端側11も車両8の荷台9から浮くことになるので、この斜脚4につき、前記上部枠2との連結部10を回動軸として外側に回動させ、斜脚4の先端側11を垂下伸張部7の先端側12に接続する。
尚、斜脚4についてもその長手方向に伸張できる構成とされており、伸びた垂下伸張部7と同様に該斜脚4も伸び、垂下伸張部7の先端側12と接続されるものとなる。
By the extension of the drooping extension portion 7, the weight of the floor slab replacement device 1 itself is held by itself, and the floor slab replacement device 1 itself can be lifted from the loading platform 9 of the vehicle 8.
As shown in FIG. 3, the tip side 11 of the slant leg 4 also floats from the loading platform 9 of the vehicle 8, so that the slant leg 4 has an outer side with the connecting portion 10 with the upper frame 2 as a rotation axis. And the distal end side 11 of the oblique leg 4 is connected to the distal end side 12 of the hanging extension 7.
The slant leg 4 is also configured to be able to extend in the longitudinal direction, and the slant leg 4 extends and is connected to the distal end side 12 of the drooping extension part 7 in the same manner as the extended drooping part 7. .

図4、図5のように、所定位置の高さ、即ち床版取り替え装置1の床版吊り具5が支障なく作業できる高さ位置まで主脚3および斜脚4を伸ばした後、その伸ばした箇所でおのおの固定し、床版取り替え装置1の工事現場での設置が終了する。   As shown in FIGS. 4 and 5, after the main leg 3 and the oblique leg 4 are extended to a height at a predetermined position, that is, a height at which the floor stool 5 of the floor slab replacement apparatus 1 can be operated without hindrance, the extension is performed. Then, the installation of the floor slab replacement device 1 at the construction site is completed.

ここで、床版取り替え装置1の設置が完了した後、床版取り替え装置1を運搬した車両8を撤去させる。   Here, after the installation of the floor slab replacement apparatus 1 is completed, the vehicle 8 carrying the floor slab replacement apparatus 1 is removed.

次に、本発明による床版取り替え装置1を稼働し、床版吊り具5によってすでに、床版剥がし装置(図示せず)などで剥がされた既設の床版を吊り上げ、吊り上げた床版は運搬用に使用する車両8の荷台に移動して載置する。
その後、剥がした床版が所定重量載置された車両8によって運搬され、所定の場所まで搬送される。
Next, the floor slab replacement apparatus 1 according to the present invention is operated, and an existing floor slab that has already been peeled off by a floor slab peeling device (not shown) or the like is lifted by the floor slab suspender 5, and the lifted floor slab is transported. It moves and mounts on the loading platform of the vehicle 8 to be used.
Thereafter, the peeled floor slab is transported by the vehicle 8 on which a predetermined weight is placed, and is transported to a predetermined location.

次に、新しい床版を積み込んだ車両8を図8に示す位置まで搬送する。
その後、新しい床版14を吊り具5などによってすでに既設の床版14を剥がした位置まで移動させ、新しい床版14の貼り替え作業が順次繰り返し行われる。
Next, the vehicle 8 loaded with a new floor slab is conveyed to the position shown in FIG.
Thereafter, the new floor slab 14 is moved to the position where the existing floor slab 14 is peeled off by the lifting tool 5 or the like, and the replacement work of the new floor slab 14 is sequentially repeated.
