Counter-directional load introduction lever apparatus introducing load apposite direction to gravity direction to the girder of bridge using the principle of a double lever and a wire

摘要

This devise is a prestressed concrete girder bridges, Preflex girder bridge, steel box girder, steel plate girder bridge, steel bridge, including new bridges and bridge hypothesis bridge installed temporarily for maintenance and bridge hypothesis of aging bridges of various types of the above as applicable to the girder,; Ganggyeol the other side of the fixing lever to the support provided in alternating or piers, and extending a width of parts of some small extension side of the upper portion of one side of the fixing lever, and by a one-way hinge axis that can only be rotated in the side of the lower one-way of the fixing lever by extending the rotation lever, and the desired distance from the lower side of the fixing lever and install the action lever and install the raising device, the lower portion of the activating lever, the other end, connected to the other end of the extension part and the action lever to the connection plate while the shackle at regular intervals at the lower end of the holding lever, install supporting axis on the activating lever to be placed in a predetermined position between the rotary lever and the hinge axis, after installing the support pedestal to the end portion of the rotating lever a plurality of the upper support and also the installation wire to the shackle by mounting a plural number of the shackle, each A connection and then making a reverse load introduction lever device by fixing the wire shackle in the top of the support,; Wherein the fabricated reverse load introduction lever device provided between the bridge girders installed on a pier or abutment, and then by the upward force of the increasing device is installed on the other end of the lower portion of the operation lever in the reverse load introduction lever device mounted on the working lever by the supporting axis of the rotating lever is the upward force of gravity in the opposite direction to the support pedestal as lifted to the upper part is installed on both side portions of the lower or the bridge girder of the bridge girder by one-way hinge axis and at the same time to introduce to the bridge girders When fixing by introducing a tensile force to each wire connected to said shackle is the adjuvant in the direction of gravity and the upward force in the opposite direction on the load introduced into the reverse way to be introduced in the bridge girder.
