As shown in FIG. 4, a rigid resin sliding member 34 is attached to the vertical surface by using a fixing tool such as a screw. The sliding member 34 prevents sliding between metals having a high coefficient of friction to improve sliding, and functions as a cushioning material at the time of displacement. The vertical surface to which the sliding member 34 is attached is the rear end surface 11c of the joint cover 11 and is perpendicular to the X direction. In the present embodiment, the sliding member 34 is attached to the vertical surface of the rear end parting material 17, but the sliding member 34 may be attached to the sliding surface 33a instead of or in addition to this.

  The side parting material 18 is a long metal member attached to the end of the cover material 12 on the side surface 11 b of the joint cover 11. In the present embodiment, a member having an L-shaped cross section as shown in FIG. 5 is used. The side parting material 18 includes a vertical surface facing a slide surface 21a described later. This vertical surface is the side surface 11b of the joint cover 11 and is perpendicular to the Y direction.

  As shown in FIGS. 1 and 5, the X-direction sliding support means 20 includes a slide support portion 21 attached to the side wall portion 41 d of one housing 41. The slide support portion 21 is a stainless plate member and is provided to protect the side wall portion 41d. The slide support portion 21 is attached in the form of a baseboard near the lower end of the side wall portion 41d. A fixing tool such as a screw is used to attach the slide support portion 21.

  This slide support part 21 is extended in the range from the flat surface 41b to the middle of the floor surface 41e when one housing 41 is seen in the X direction. The lower end edge of the slide support portion 21 is formed along the upper surfaces of the flat surface 41b, the inclined surface 41c, and the floor surface 41e. Further, the surface of the slide support portion 21 forms a slide surface 21a perpendicular to the Y direction. As shown in FIGS. 5B and 5C, the slide surface 21a extends in the X direction. For this reason, when the joint cover 11 moves in the X direction along the upper surfaces of the flat surface 41b, the inclined surface 41c, and the floor surface 41e, the slide surface 21a faces the side surface 11b of the joint cover 11, and along the slide surface 21a. Thus, the joint cover 11 slides smoothly.

  Further, as shown in FIG. 5B, a rigid resin sliding member 34 is attached to the slide surface 21a using a fixing tool such as a screw. The sliding member 34 prevents sliding between metals having a high coefficient of friction to improve sliding, and functions as a cushioning material at the time of displacement. In the present embodiment, the sliding member 34 is attached to the slide surface 21a. However, instead of or in addition to this, the sliding member 34 may be attached to the side surface 11b of the joint cover 11.

  As shown in FIGS. 1, 2, and 4, the Y-direction sliding support means 30 includes a base metal fitting 31, a receiving rail portion 32, and a sliding support portion 33.

  The base metal fitting 31 is a metal fitting attached to the wall surface 42a of the other casing 42 in an inverted L shape. The base metal 31 is a long material for supporting the receiving rail portion 32 and the joint cover 11 from below. The base metal 31 is provided with a length capable of supporting the entire length of the receiving rail portion 32 from below, and is attached to the wall surface 42a of the other housing 42 using a fixing tool such as a bolt.

  The receiving rail portion 32 is a long metal member having a substantially C-shaped cross section that opens upward. The receiving rail portion 32 is attached to the upper portion of the base metal fitting 31 using a fixing tool such as a bolt. As shown in FIG. 4, the receiving rail portion 32 is formed such that a first rising portion 32 a and a second rising portion 32 c are vertically raised in parallel with each other. The one closer to one housing 41 is the first rising portion 32a, and the one farther from one housing 41 is the second rising portion 32c. The tip of the first rising portion 32a is refracted inward to form a retaining portion 32b, and the tip of the second rising portion 32c is refracted inward to form a support fixing portion 32d.

  The first rising portion 32 a and the retaining portion 32 b are for hooking and engaging the rail material 16 of the joint cover 11. As shown in FIG. 4A, when the rail material 16 is hooked on the retaining portion 32b, the rail material 16 is supported on the upper surface of the retaining portion 32b so as to be slidable in the Y direction, and the joint cover 11 is moved upward. Even if it moves, the rail member 16 is formed so as not to fall off the retaining portion 32b.

  The second rising part 32 c and the support fixing part 32 d are parts for attaching the sliding support part 33.

  The sliding support portion 33 is a long metal member having a substantially U-shaped cross section. The sliding support portion 33 is attached to the upper surface of the support fixing portion 32d using a fixing tool such as a screw.

  The receiving rail portion 32 and the sliding support portion 33 described above have substantially the same length, and are set longer than the joint cover 11 when viewed in the Y direction. As a result, the sliding of the joint cover 11 in the Y direction can be supported.

  Moreover, the sliding support part 33 is provided with the sliding surface 33a perpendicular | vertical with respect to the X direction. Since the sliding surface 33a extends in the Y direction, when the joint cover 11 moves in the Y direction along the receiving rail portion 32, the sliding surface 33a faces the rear end surface 11c of the joint cover 11 and slides. The joint cover 11 slides smoothly along the surface 33a.

  When the sliding support portion 33 is attached to the receiving rail portion 32, the upper opening of the receiving rail portion 32 is narrowed. Thereby, the rail material 16 of the joint cover 11 engaged with the receiving rail part 32 is prevented from falling off. For this reason, the joint cover 11 is attached to the Y direction sliding support means 30 in the following procedure at the time of an assembly | attachment.

  That is, as shown in FIG. 4B, first, the receiving rail portion 32 is attached to the upper surface of the base metal 31. Next, the rail member 16 of the joint cover 11 is engaged with the receiving rail portion 32. Finally, the sliding support portion 33 is attached to the receiving rail portion 32. Thus, by attaching the sliding support portion 33, the opening of the receiving rail portion 32 is narrowed to prevent the joint cover 11 from falling off. Moreover, since the play of the joint cover 11 is suppressed by the sliding support part 33, the joint cover 11 can be smoothly slid.

  According to the expansion joint cover device 10 as described above, since the joint cover 11 can move in both the X direction and the Y direction, it is possible to cope with a large displacement caused by an earthquake or the like.

  That is, when displacement in the X direction occurs, the joint cover 11 moves along the flat surface 41b, the inclined surface 41c, and the upper surface of the floor surface 41e of one housing 41 as shown in FIGS. Then, the side surface 11b of the joint cover 11 is supported by the X-direction sliding support means 20, and the joint cover 11 slides.

  Specifically, as shown in FIG. 6, when the two casings are displaced so as to approach each other, the tip member 14 of the joint cover 11 is guided to ride on the inclined surface 41c. At this time, since the front end member 14 is provided in the Y direction, the end of the reinforcing member 15 provided with a gap in the Y direction does not hit the inclined surface 41c, and can slide smoothly.

Further, as shown in FIG. 7, when the displacement is such that the two casings are separated, the tip member 14 of the joint cover 11 slides in the direction of the gap 50 along the flat surface 41 b.
When the displacement in the Y direction occurs, the joint cover 11 slides along the Y direction sliding support means 30 as shown in FIGS.

  As described above, according to the present embodiment, the X-direction sliding support means 20 that is attached to one housing 41 side and supports the joint cover 11 so as to be movable in the X direction, and the other housing 42 side. Since the Y-direction sliding support means 30 that is attached and supports the joint cover 11 so as to be movable in the Y-direction is provided, not only the X-direction but also the displacement in the Y-direction can be dealt with. Therefore, for example, when there is a side wall 41d on both sides of the joint cover 11, even when a displacement in the Y direction occurs, the joint cover 11 can be prevented from hitting the side wall 41d, and the side wall 41d can be prevented from being damaged.

The Y-direction sliding support means 30 includes a receiving rail portion 32 provided with a retaining portion 32b that engages with the joint cover 11, and a sliding support portion 33 that faces the rear end surface 11c of the joint cover 11. The sliding support portion 33 includes a sliding surface 33a perpendicular to the X direction and extends in the Y direction. According to such a configuration, the sliding of the joint cover 11 can be guided by the receiving rail portion 32 even when the two casings are relatively displaced in the Y direction. Even if the joint cover 11 is loose in the height direction, the rear end surface 11c of the joint cover 11 always faces the sliding surface 33a, so that the joint cover 11 slides smoothly on the sliding surface 33a. . Therefore, the joint cover 11 is prevented from being caught, smooth sliding and member damage prevention can be realized, and a large displacement due to an earthquake or the like can be dealt with.
Further, since the joint cover 11 includes the reinforcing material 15 that is fixed with a gap in the Y direction, the strength of the joint cover 11 increases in the X direction.

  Further, since the resin sliding member 34 is attached to the sliding surface 33a or the rear end surface 11c of the joint cover 11 facing the sliding surface 33a, the joint cover 11 can be slid more smoothly.

  The X-direction slide support means 20 includes a slide support portion 21 that faces the side surface 11b of the joint cover 11. The slide support portion 21 includes a slide surface 21a that is perpendicular to the Y direction, and X Extends in the direction. According to such a configuration, even when the two casings are relatively displaced in the X direction, the sliding of the joint cover 11 can be stably guided. Even when the joint cover 11 moves in the height direction, the side surface 11b of the joint cover 11 always faces the slide surface 21a, so that the joint cover 11 slides smoothly on the slide surface 21a. Therefore, the joint cover 11 is prevented from being caught, smooth sliding and member damage prevention can be realized, and a large displacement due to an earthquake or the like can be dealt with.

  Further, since the resin sliding member 34 is attached to the slide surface 21a or the side surface 11b of the joint cover 11 facing the slide surface 21a, the joint cover 11 can be slid more smoothly.

  In the above-described embodiment, the expansion joint cover device 10 is disposed between the two floor surfaces 41e and 42b. However, the present invention is not limited to this, and for example, as shown in FIG. In the structure in which the wall surface 42a of the other housing 42 faces, the expansion joint cover device 10 may be disposed between the floor surface 41e of the one housing 41 and the wall surface 42a of the other housing 42.

  Moreover, in the above-described embodiment, an example in which the sheet-like finishing material 13 is used has been described. . In this case, for example, as shown in FIG. 11, the cover material 12 may be formed in a U-shape in which the cross-sectional shape is opened upward, and the finishing material 13 may be disposed inside the cover material 12. In this way, when the upward U-shaped cover material 12 is used, the side parting material 18 may be omitted, and the side surface 11b of the cover material 12 may face the slide surface 21a. When the reinforcing material 15 is used, the reinforcing material 15 may be attached to the inside (upper surface) of the cover material 12.

  Moreover, as shown in FIG.12 and FIG.13, the finishing material 13 does not need to be used. For example, a striped steel plate may be used for the cover material 12 and the cover material 12 may also serve as the finishing material 13.
