They are connected so as to be rotatable in the vertical direction, and the gap T between the frames W and v is covered.

Note that 22 in the figure is a floor member attached to the floor W.

Next, the operation and effect of this embodiment configured as described above will be explained.

In this embodiment, for example, the floor W and wall V of adjacent buildings
A mounting member 4 that is attached to the floor W and has a groove 4G that is open from above.
and a lid member for closing the groove 4G, and a folding piece 6C having elasticity at the lower end is provided on the wall W' surface 91 to form a retainer #13D. A plurality of fixing members 5 are arranged at predetermined intervals in correspondence with the fixing members 2, and an engagement groove 6D is provided between the fixing members 3 to 6 on the wall W' side between the fixing members 2 and 3. A cover unit consisting of a wall plate member 8 which is elastically engaged with the wall plate member 8 and a cover member 7 which is fixedly supported by a connecting groove 8K formed in the wall plate member 8 and whose other end is supported by the fixing member 2 of the floor WllII. A member 6 is interposed therebetween, and the flexible member 7 is configured to be able to enter into the groove 4G of the fixed member 2 on the floor W side, and to be rotatable in the vertical direction around the connecting groove 8K of the wall plate member 8. This is what I did. Therefore, the cover member 6 is composed of two members, the cover member 7 and the wall plate member 8, and the cover member 7 is supported so that its one end side can enter and exit the groove 4G of the fixed member 2, and its installation width can be expanded and contracted. (possible), and the other end of the cover member 7 is configured to be engaged with the connecting groove 8K of the fixing member 3 in an elbow-like manner so as to be rotatable in the vertical direction.
For example, as shown in FIG. 3, even if the frames W and v move apart in the left-right direction and the gap T becomes a large gap T2, the fixing member 2 and the covering member 7 become elongated and close the gap T2. The shielding state can be maintained, and conversely, even when the skeletons W and 'W' come close to each other, the fixing member 2 and the cover member are in a contracted state, and the gap can be maintained in a shielding state. Further, as shown in FIG. 5, for example, when the floor W side moves downward relative to each other, the cover member 7 is rotated downward around the connecting groove 8K. It becomes elongated and the gap TO
It is possible to maintain a hidden state. Further, in the case of relative movement in the opposite direction, the same effect is applied, and it becomes difficult to maintain the shielded state of the gap T by coping with the relative movement of the buildings. In addition, the cover member 6 has its wall plate member 8 elastically engaged with the fixing member 3, and the cover member 7 has one end fixedly supported in a connecting groove 8K formed in the wall plate member 8, and the other end The mount can be supported in the groove 4G of the fixing member 2 in an extremely labor-saving manner, and since no fastening member is required, the appearance can be improved. In addition, since the fixing member 2 disposed on the floor W side has a groove 4G in its mounting member 4, on the floor WgA where a lot of water is used, this water is received by the groove 4G and stopped through the drain hole 4H. Water can be actively drained to the plate 1101I for water treatment.

Next, the locking point 11 shown in FIG.
An anchoring piece 4K is provided along the lower surface of the web 14 to be attached to an anchor member 23 buried in the floor W, and a mounting piece 4L is provided.The other configuration is the same as that of the above embodiment. Since they are the same, I added 10 to the same number and added them. Therefore, this Jiso India 11 also obtains the same effect as the above embodiment.

In the above embodiment, the elbow piece 7E of the cover member 7 is engaged with the connecting groove 8K formed in the wall board member 8, and the structural shape of the elbow piece 7E is limited to the connecting groove 8K. In short, any structural shape of the joint part that allows the covering member 7 to rotate in the vertical direction with respect to the wall plate member 8 is sufficient. Alternatively, the fixing member 3.13 may be long.

Specifically, the present invention relates to an expander VW engine which is installed between, for example, a floor and a wall of adjacent buildings to shield the gap therebetween, the installation having an upwardly opening groove in the floor. A fixing member consisting of a member and a lid member for closing the same groove portion is disposed, and the lower end part is provided with elasticity on the wall surface side, and a nine-folded piece is provided to provide a locking groove. are arranged in correspondence with the fixing member, and between the two fixing members, there is a wall board member elastically engaged with the engagement groove of the fixing member on the wall side. A cover member is interposed, one end of which is fixed and supported in a connecting groove formed in the plate member, and a cover member whose other end is supported by the fixing member on the floor side, and the cover member is fixedly supported by the floor side fixing member. By being configured to be able to move in and out of the groove of the second fixed member and to be able to rotate vertically around the connecting groove of the wall plate member, relative movement of adjacent buildings can be coped with. It is possible to maintain the state of shielding the gap between each other, and the cover member can be used to connect the cover member and the wall board member to each other.
Since it is made up of members, installation between buildings can be carried out labor-savingly, and since the installation of this cover member does not require fastening members, the appearance can be improved. In addition, since a groove is formed in the floor-side mounting member, wastewater treatment can be actively carried out, making it extremely useful as an expansion exchanger.
