〔発明の利用分野〕
本発明は任意の場所に移動して応急的に橋梁を架設する
自走式橋梁に係り、特に路上移動時には車両幅を縮小し
、橋梁架設時には橋床幅を拡大するのに好適な橋梁の構
造に関するものである。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a self-propelled bridge that moves to any location and erects a bridge in an emergency manner. The present invention relates to a bridge structure suitable for expanding the width of the bridge deck.
従来の橋梁は、路上移動時には幅方向に数個に分割した
ものを車体上に上下に積重ねて積載し、橋梁構成時には
クレーンにより幅方向に並べて設置することにより橋床
幅を拡大させていたので、車両にクレーンを搭載する必
要があり構造が複雑となるのみならず、架設のための所
要時間が大きくなるという欠点があった。In conventional bridges, when moving on the road, the pieces are divided into several parts in the width direction and stacked vertically on the vehicle body, and when the bridge is constructed, the bridge deck width is expanded by installing them side by side in the width direction using a crane. However, there was a drawback that not only did the structure become complicated as it required a crane to be mounted on the vehicle, but the time required for erection was also increased.
また、従来の他の橋梁は幅方向に２分割し、路上走行時
にはこれを密着させて車両に積載し、橋梁構成時にはこ
れを幅方向に左右に移動させて橋床幅を拡大させていた
ので、寸法も重量も大きい橋梁を左右に移動させるため
の動力が大きくなるという欠点があった。In addition, other conventional bridges were divided into two parts in the width direction, and when driving on the road, they were loaded onto vehicles in close contact with each other, and when the bridge was constructed, they were moved from side to side in the width direction to expand the width of the bridge deck. However, the drawback was that it required a large amount of power to move the bridge, which was large in size and weight, from side to side.
本発明の目的は、路上走行時には幅を縮少し、橋梁架設
時には幅を拡大し、その姿勢変換を簡単な機構で短時間
で行うことのできる橋梁を提供することにある。An object of the present invention is to provide a bridge that can reduce its width when traveling on the road, expand its width when it is constructed, and change its posture in a short time with a simple mechanism.
本発明は、橋梁の主桁を車両の幅よりも狭い間隔に配設
し、その上部に転回可能な踏板を設けたことを特徴とし
ている。The present invention is characterized in that the main girders of the bridge are arranged at intervals narrower than the width of the vehicles, and that a rotatable treadle is provided on the upper part of the main girders.
以下、本発明の一実施例を第１〜２図により説明する。 An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

けられている。１０は主桁１間を結合する横梁である。Figure 1 is a cross-sectional view of the bridge when it is unfolded. The width B of the main girder l is arranged at intervals narrower than the width of the car body, and the tread plate 2 is provided closely on the upper surface of the main girder l, and the tread plate @A passes over it. It is large enough for the vehicle. Main girder 1 and treadle 2 are hinge bins 3
The cylinder 51 is connected rotatably through the bottle holder 4 and the cylinder 51 is connected to the arm 6 and the cylinder 7 to rotate the cylinder 51. The cylinder 5 is provided between the tread plate 2 and the arm 6, and the arm 6 is connected to the center pin 8. It is rotatably supported by the main girder I by a bottle support 9. Further, the cylinder 7 is provided between the arm 6 and the main girder 1. 10 is a cross beam that connects the main girders 1.

桁ｌの接触面１１およびヒンジピン３を通じて主桁ｌへ
伝達される。A load F acting on the treadle 2 by a passing vehicle is transmitted to the main spar l through the contact surface 11 between the treadle 2 and the main spar l and the hinge pin 3.

に約１８０度程度回転して収納状態となる。Figure 2 is a cross-sectional view of the bridge when it is stored.When the cylinder 5 connected to the tread plate 2 is extended and the cylinder 7 connected to the main girder l is contracted, the tread plate 2 moves around the hinge bin 3. It rotates about 180 degrees and enters the storage state.
本実施例によれば、収納状態において主桁１と踏板２は
車体１２の幅Ｂ′以内に縮少せしめ得る効果がある。ま

る。According to this embodiment, the main girder 1 and the footboard 2 can be reduced to within the width B' of the vehicle body 12 in the stored state. In addition, the width of the bridge body is expanded in the unfolded state, and the tread plate 2
This has the effect of supporting the load acting on the main girder l on the top surface.
本発明によれば、路上走行時に幅を縮少できるので移動

間を小にでき、所要動力も小にできる効果がある。According to the present invention, since the width can be reduced when traveling on the road, it is possible to easily carry out traffic when moving. Also,
Since the width of the bridge body can be expanded when the bridge is constructed, it has the effect of preventing vehicles passing over the bridge from falling. Furthermore, since it has a simple structure in which the treadle is rotated, the time required for posture change can be reduced, and the required power can also be reduced.
