Description

  The present invention relates to a floor joint device and a joint plate for closing a joint portion between left and right housings provided via joint portions in a state in which a heavy object such as a vehicle can pass.

  Conventionally, this type of floor joint device or floor joint plate is made of a metal plate-shaped shallow plate-shaped joint plate body, concrete or mortar filled in the joint plate body, and the top surface of the concrete. Tiles such as marble pasted on the floor, bricks and other floor decorative panels, pin boxes attached to both sides of one end of the joint plate body, and a lower end opened through a hinge member A joint plate made up of a cover plate attached to each other is widely known.

  Also, there is a wide variety of floor joint devices in which the joint plate is supported in a joint plate support recess formed on one housing and a joint plate slide support recess formed on the other housing on the inclined surface on the opposite joint portion side. Are known.

  In such floor joint devices and joint plates, the left and right housings move due to the earthquake, and when the joint portion becomes narrow, the other end is lifted by the inclined surface, the joint plate rises in an oblique state, Absorbs shaking motion.

  However, when the joint plate rises in an oblique state and absorbs the shaking motion caused by the earthquake, the vehicle or the like is traveling near the joint plate (for example, the front wheel portion is located on the joint plate and the rear wheel portion is on the other housing). If an earthquake occurs and the joint plate rises in a slanted state momentarily, the other end of the joint plate may collide with the bottom of the vehicle, which may damage the vehicle or cause an accident. It was.

  Therefore, there is a joint plate that does not rise like this and is substantially horizontal when the joint plate is raised. For example, “a joint plate slide support concave portion formed on the joint surface side floor surface of one floor housing of the left and right floor housings provided through the joint portion, the joint surface side being an inclined surface, and this joint plate slide support The front end is supported by the recess so as to be slidable, the rear end can be pivoted upward, and the rear end can be moved upward, toward the joint of the other floor frame of the left and right floor frame. A joint plate that is mounted in this manner, an inclined joint plate push-up piece that is provided on the bottom surface near the rear end of the joint plate, and whose rear end side is positioned downward, and the joint of the one floor frame When the joint becomes narrow due to an earthquake, it is engaged with the joint plate push-up piece, and a push-up mechanism using a roller that pushes the joint plate push-up piece upward, and a tip of the joint plate. Floor joint device "which is characterized by being composed by the vignetting cover plate is known (Patent Document 1).

  However, even if such a joint plate or floor joint device is used, if the joint plate completely rides on the joint plate slide support part, the pin may fall off the joint plate, and the pin may fall off. In other words, there was a drawback that the normal state could not be restored after the shaking motion due to the earthquake ended.

  In addition, although the joint plate is in a substantially horizontal state when it is pushed up, the one end side is in an unstable state because the inclined surface of the push-up piece and the roller of the other housing are only in line contact with each other Met.
