Description

  The present invention relates to a floor joint device for covering between left and right housings provided via joint portions.

  Conventionally, the floor joint device that covers the space between the left and right housings provided through the joint portion using a number of joint plates, even if the joint portion at the time of an earthquake is widened or narrowed, After the joint plate, the tip of which overlaps a plurality of joint plate support bars arranged at predetermined intervals on at least two or more bar members of the support mechanism having at least two or more bar members capable of absorbing the shaking motion. The end is attached.

For this reason, when the joint plate is shaken by an earthquake, there is a drawback that if the joint plate is loaded, the resistance is large and the joint plate cannot move smoothly.
In addition, when the joint portion becomes narrow due to an earthquake, the overlapping area of the joint plates becomes large, that is, there is no problem because the interval between a large number of joint plate support bars becomes narrow, but when the joint portion becomes wide, a large number of joints. When the interval between the plate support bars is wide and a load is applied to the joint plate, there is a drawback that the joint plate is bent.

  For this reason, the interval between the large number of joint plate support bars 6 is increased, and the overlapping area of the joint plate plates 7 is reduced. However, the support bar of the joint plate support mechanism 8 is provided at a substantially central portion between the joint plate support bars 6 and 6. 16 is located, and the joint plate 7 is supported at a substantially central portion between the joint plate support bars 6 and 6 by a plurality of rollers 17 attached to the support bar 16.

  Therefore, even if a large load is applied to the joint plate 7, the joint plate 7 can be efficiently prevented from being bent and the slide movement of the joint plate 7 is supported by the plurality of rollers 17 of the joint plate support mechanism 8. Therefore, the slide can be moved more smoothly.

  When the joint 2 is swung so as to be narrowed, the joint plate 2 moves so that the distance between the joint plate support bar 6 and the support bar 16 of the joint plate support mechanism 8 is narrowed.
