A cover member having an elbow piece connected in an elbow-like manner so as to be able to rotate up and down about the connecting groove is interposed, and the wall plate member is engaged with a lower folded piece of the mounting member to connect the connecting groove. By having a position-adjustable configuration, it is possible to cope with the relative movement of adjacent buildings and maintain a state of shielding the gaps between them.In addition, grooves are formed in the floor-side mounting members to facilitate drainage treatment. In addition, since the wall fixing member is inserted into and engaged with the engagement grooves of the upper and lower folded pieces of the mounting member arranged on the wall at predetermined intervals, it is almost a one-touch operation. This allows for reliable, strong and labor-saving assembly without the need for fastening members, etc., and improves the appearance by shielding the head of the mounting bolt of the mounting member. The wall board member is engaged with the mounting member of the fixing member by engaging the engagement portion with the appropriate position on the engagement surface, so that the position of the connecting groove relative to the floor fixing member can be easily set.
In addition, since the connecting groove is recessed along the longitudinal direction of the wall fixing member, the intervening position of the cover member relative to the wall side can be clearly determined, and the elbow joint-like assembly can be performed smoothly and reliably. In conjunction with the insertion and support of the floor fixing member, it is possible to prevent the cover member from coming off and maintain a stable shielding state at all times, making it extremely useful as an expansion joint.
