It is detachably fitted.

Next, the operation mode of the floor joint cover device having such a configuration will be described.
When the building A and the adjacent building B are relatively displaced in an earthquake, the free end of the cover body C slides horizontally on the support step 1 within the operating gap 15. Follow the relative displacement.

  Further, when the building A and the adjacent building B are relatively displaced in the direction away from each other, the cover body C slides horizontally on the support step edge 1 in the direction opposite to the rising edge 3b. And follow the relative displacement.

  When the building A and the adjacent building B are relatively displaced in the front-rear direction (the direction along the joint s), the free end of the cover body C slides on the support step edge 1 in the front-rear direction. Follow relative displacement. Furthermore, when the building A and the adjacent building B are relatively displaced in the vertical direction, the cover body C has the one end connected to the side edge of the floor f1 of the building A by the connecting means 27 as a fulcrum. It tilts with the vertical movement of A or the adjacent building B and follows its relative displacement.

  In this configuration, the holding receiving frame 16 disposed on the side edge of the floor f1 of the building A to which one end of the cover body C is connected extends in the direction along the joint s at the same height as the floor f1. By providing the water passage gap 20 to be operated, even if a plurality of cover bodies C are individually displaced in the width direction of the joint s due to an earthquake or vibration caused by passage on the cover body C, the displacement is affected. Therefore, a state where the water passage gap 20 is always continuously arranged in the direction along the joint s can be obtained, and the external appearance can be improved as compared with the conventional configuration. Further, the holding receiving frame 16 is provided with a drainage passage 23 provided with the water passage gap 20 in the upper portion and a communication gap 22 communicating from the water passage gap 20 through the lower portion of the cover body C to the joint s.
