In this state, the hinge portion 46 may be in direct contact with the contact portion 52, but the film 66 is disposed on the placement surface, and the hinge portion 46 is placed on the placement surface 56 via the film 66. It is also possible to adopt a configuration in which they are placed.

  From this state, for example, when the separation distance L between the two buildings is increased due to an earthquake or the like, the hinge portion 46 moves in the separation direction X1 from the contact portion 52, and the separation distance L between the two buildings is normally set again. When returning to this state, the hinge part 46 gets on the contact part 52 again. When the hinge portion 46 is displaced in the one direction X1 away from the contact portion 52, the separation direction support member 34 prevents the hinge portion 46 from being displaced downward Z2, and the hinge portion 46 is placed by deflection or the like. There is no displacement below the surface 56 in the direction Z2.

  FIG. 6 is a cross-sectional view perpendicular to the width direction Y of the end portion in the separation direction other X2 of the assembly panel body 16 in the embodiment of the present invention. FIG. 6 shows a state when the separation distance L between two buildings is shorter than a predetermined distance. When the separation distance L between the two buildings becomes shorter than a predetermined distance, the hinge portion 46 is displaced in the other direction X2 from the contact portion 52 in the separation direction. In this case, the assembly panel body 16 rides on the inclined portion 54 by the hinge portion 46 coming into contact with the inclined surface 57 formed on the inclined portion 54 and riding on the inclined surface 57.

  Accordingly, when the separation distance L between the two buildings is shorter than a predetermined distance due to an earthquake or the like, the hinge portion 46 moves to the upper side Z1 from the inclined portion 54, so that the assembly panel body 16 is moved in the separation direction X. Bending or buckling due to external force in the compressing direction is prevented. Further, since the assembly panel body 16 is allowed to be angularly displaced around the rotation axis 17 positioned at the end portion X1 in the separation direction, a part of the assembly panel body 16 rides on the upper side Z1 above the inclined portion 54. Therefore, the assembly panel body 16 is not damaged.

  When the hinge part 46 of the assembly panel body 16 is displaced upward Z1 from the inclined part 54 of the second edge member 14, the hinge part with respect to the floor surface located in the other direction X2 away from the second edge member 14. 46 will be in a raised state. When the floor surface of the other housing 12 in the other direction X2 away from the second edge member 14 is referred to as a “body floor surface” (58), the hinge portion 46 is in a state where the hinge portion 46 rides on the inclined portion 54. And a difference in level between the housing floor 58. The auxiliary cover body 48 closes a step formed between the hinge portion 46 and the frame floor surface 58. The auxiliary cover body 48 is angularly displaced based on its own weight via the hinge piece 49, and forms an inclined surface in a range from the upper part Z <b> 1 of the hinge part 46 to the frame floor 58. The inclined surface is inclined downward Z2 toward the other side X2 in the separation direction, thereby relieving a traffic obstacle based on the step.

  When the auxiliary cover 48 is angularly displaced based on its own weight, if the level difference is small, the other end X2 of the auxiliary cover 48 is in contact with the frame floor 58 so that further angular displacement is prevented. The When the level difference is large, a part of the hinge piece 49 comes into contact with the hinge portion 46 or the screw member 44 that attaches the hinge portion 46 to the connecting panel member 18 or the like. Displacement is prevented. As a result, the auxiliary cover body 48 is not angularly displaced to a vertical state. Therefore, even if the separation distance L between the two buildings repeatedly expands and contracts due to an earthquake or the like, and the step between the hinge portion 46 and the building floor surface expands and contracts, the auxiliary cover body 48 remains below the connection panel member 18. It is possible to prevent a state of being caught in Z2.

Since the connection panel member 18 is firmly positioned by the adjacent member in a state where the connection panel member 18 is connected to the adjacent member by the fitting convex portion 21 and the fitting concave portion 22, the connection panel member 18 is not necessarily separated from the lower Z2 of all the connection panel members 18. The direction support member 34 is not necessary.

  The upper surface of the assembly panel body 16 may be formed with the upper surface of the connection panel member 18 exposed. However, in order to unify the color and material of the building floor surface, one or more sheet-like members 68 are used. It may be formed by coating.

  Furthermore, the recess-side insertion member 96 can be displaced in the width direction Y with respect to the recess-side panel in a state where at least a part is inserted into the recess-side space forming portion 94. Thereby, the width direction dimension of the assembly panel body 16 can be finely adjusted.

  Furthermore, the relative position of the convex portion side insertion member 93 with respect to the convex portion side panel member 86 in a state where at least a part is inserted into the convex portion side space forming portion 92 is the width direction dimension of the plurality of types of connection panel members 18. The width of the connecting panel member 18 can be changed to the width direction Y within a range equal to or smaller than the width direction dimension. As a result, if one connecting panel member 18 arranged in the width direction Y is added and the width direction dimension of the assembly panel body 16 exceeds the required dimension, the protrusion side insertion member with respect to the protrusion side panel member 86 is obtained. By changing the relative position of 93, the width direction dimension of the assembly panel body 16 can be set to a required dimension. Therefore, an assembly panel having an arbitrary width dimension can be easily constructed.

  Furthermore, if the sum of one or both of the convex portion side insertion position variable amount and the concave portion side insertion position variable amount is set to be equal to or larger than the minimum width dimension, the width direction dimension of the assembly panel body 16 is set to an arbitrary dimension. It becomes possible to set.
