  FIG. 1 shows an expansion joint structure according to the present invention. This expansion joint is formed by providing a cover member 3 between a vertical wall member 1 and a horizontal ceiling member 2, and the cover member 3 is made of aluminum. It is comprised from the extrusion shape material.

  The wall material 1 is not straight in a plan view, and can be attached to the window frame 4 that partially protrudes indoors. For this reason, as shown in FIG. 2 and FIGS. 5A and 5B, the window frame 4 of the wall material 1 protrudes indoors as a parting material.

  The ceiling material 2 is attached to the lower part of the base material. The base material adopts an earthquake-resistant structure, and the field edge receiver 6 is fixed to the suspension bolt 5 suspended from the ceiling frame of the building, and the field edge 7 as the base material of the ceiling material 2 is fixed to the field edge receiver 6. Has been. The field edge receiver 6 is supported by the suspension bolt 5, but is further supported by a brace 8 to ensure earthquake resistance.

  On the other hand, as shown in FIG. 3, the cover material 3 is formed by forming a first edge 10 and a second edge 11 into an L-shaped cross section, and the first edge 10 and the second edge 11. A dovetail groove 12 is formed on each inner side surface. The widths of the first edge 10 and the second edge 11 are different from each other, and the width dimension of the first edge 10 is smaller than the width dimension of the second edge 11. Further, fine corrugated strips 13 (including angular corrugations) are formed on the outer surfaces of the first edge 10 and the second edge 11 along the longitudinal direction of the cover material 3. Furthermore, a flat portion 14 is provided on the outer surface of the wide second edge 11 on the wall material 1 side of the uneven strip 13.

  Next, when the cover member 3 is attached to the wall member 1 having the protruding portion (window frame 4) as shown in FIG. 2, the support width of the ceiling member 2 must be the same between the A portion and the B portion. Therefore, it is necessary to make the portion B narrower than the portion that supports the ceiling material 2. In that case, a part of the cover material 3 may be cut out according to the unevenness of the wall material 1, but the work is troublesome. Therefore, when the cover material 3 is fixed to the wall material 1 with the bolts 15, in the part A, the narrow first edge 10 is fixed and the wide second edge is fixed as shown in FIG. 11 is projected horizontally. And in B part, as shown in the same figure (b), the 2nd wide edge 11 is fixed, and the 1st narrow edge 10 is projected horizontally. According to this, since the tip part of the 2nd edge 11 and the 1st edge 10 which protruded horizontally becomes the same, since the cover material 3 looks continuously in A part and B part, the design property is good. Moreover, the width | variety of the support surface of the ceiling material 2 becomes the same, and the ceiling material 2 can be supported uniformly by A part and B part.

  Furthermore, in part A, a flat part 14 is provided on the outer surface of the wide second edge 11 of the cover material 3 on the wall material 1 side of the ridges 13 and, as shown in FIG. 14 is configured to be continuous with the frame member 16 of the window frame 4. In addition, the uneven strip 13 inside the flat portion 14 is also continuously formed by the A portion and the B portion. For this reason, the designability is good.

  As described above, the lengths of the second edge 11 and the first edge 10 of the cover material 3 are different from each other, and the second edge 11 and the first edge 10 according to the gap between the A part and the B part. In order to correspond to different gaps by simply replacing the one edge 10 and mounting, for example, the width dimension w1 of the first edge 10 is 38 mm, the width dimension w2 of the second edge 11 is 50 mm, and the flat portion 14 The width dimension w3 and the width dimension w4 of the frame member 16 of the window frame 4 as a parting material may be set to the standard size 12 mm. The gap between the end of the ceiling material 2 and the wall material 1 is such that the gap s1 in the A portion is about 25 mm and the gap s2 in the B portion is about 15 mm.

  Next, the cover material 3 arrange | positioned at the said A part and B part is connected in a straight shape. Moreover, the cover material 3 is connected at a right angle at the corner of the room space where the ceiling material 2 is arranged.

  When two cover members 3 are connected in a straight shape, as shown in FIGS. 4A, 4B and 6A, the first edges 10 or the second edges of the cover members 3 adjacent to each other are continuously provided. Each of the connecting plates 17 may be inserted into the dovetail groove 12 formed on the edge 11 of the halves. When two cover members 3 are connected at right angles, as shown in FIG. 6B, the end surfaces of adjacent cover members 3 are cut off at 45 degrees with respect to the longitudinal direction so as to be continuous. If the connecting plate 17 bent at a right angle is used and the connecting plate 17 is inserted into the dovetail grooves 12 formed in the first edge 10 or the second edge 11 of the cover material 3 adjacent to each other at a right angle in half, respectively. Good.

  Next, as shown in FIGS. 4 (a) and 4 (b), the end portion of the ceiling material 2 abuts on the first edge 10 or the second edge 11 disposed horizontally of the cover material 3. Supported.

  When the wall material 1 does not protrude and the wall material 1 is provided in a planar shape as in the above embodiment, the first edge 10 having a narrow width is fixed vertically to the wall material 1. Then, the ceiling material 2 is supported with the wide second edge 11 horizontal, or fixed to the wall material 1 with the wide second edge 11 vertical, and the narrow first edge 10 is horizontal. The ceiling material 2 may be supported.

  As described above, the gap s <b> 1 (s <b> 2) is provided between the end of the ceiling material 2 and the wall material 1, and the end of the ceiling material 2 of the ceiling base material having a seismic structure is connected to the first of the cover material 3. Since the structure is supported by being brought into contact with the edge 10 or the second edge 11, even if the ceiling material 2 and the wall material 1 move relatively due to an earthquake or the like, the space between the ceiling material 2 and the wall material 1 By the gap s1 (s2), the displacement generated between the ceiling material 2 and the wall material 1 can be effectively absorbed, and the ceiling material 2 can be effectively prevented from being damaged or dropped.

  Since the cover material 3 is formed in an L-shaped cross section, the ceiling material 2 and the first edge 10 (or the second edge 11) that supports the ceiling material 2 are substantially flat, uniform, and designed. Good sex. Moreover, since the cover material 3 can be fixed only by fixing one edge of the cover material 3 to the wall material 1, workability | operativity is good.

  Furthermore, it is the structure which provided the uneven | corrugated strip 13 in each outer surface of the 1st edge 10 and the 2nd edge 11, and whichever of the 1st edge 10 and the 2nd edge 11 supports the ceiling material 2 Since the uneven strip 13 appears on the outer side of the cover material 3, that is, the lower surface of the first edge 10 or the second edge 11 supporting the ceiling material 2, the design is further improved.

  Further, when a part of the surface of the wall material 1 is formed in a convex shape as described above, the gaps s1 and s2 between the ceiling material 2 and the wall material 1 are not the same, but the cover material 3 Since the widths of the second edge 11 and the first edge 10 are different, only the second edge 11 and the first edge 10 are replaced and attached according to the gap, so that different gaps can be handled. For example, as in the above embodiment, when the width of the first edge 10 is smaller than the width of the second edge 11 and the gap is relatively wide, approximately 25 mm, the longer second edge 11 is extended horizontally to support the ceiling material 2, and when the gap is relatively narrow about 15 mm, the shorter first edge 10 is horizontally extended and the longer second edge 11 is attached to the wall material 1. By fixing, the ceiling material 2 can be supported efficiently. Therefore, it is not necessary to produce molds with various dimensions, and costs can be reduced. And since the uneven | corrugated strip 13 continues, there exists a sense of unity.

  And since the flat part 14 was provided in the wall material 1 side of the said uneven | corrugated strip 13 in the outer surface of the 2nd edge 11, this flat part 14 is set to the same dimension as the standard size (about 12 mm) of a parting material. By doing, it becomes the structure which continued from the cover material 3 to the separate parting material, and its design property is good.

  The first edge 10 of the cover material 3 is shorter than the second edge 11, the second edge 11 is horizontally disposed to support the ceiling material 2, and the end portion and the wall of the ceiling material 2 Since the gap with the material 1 is about 25 mm, when a part of the surface of the wall material 1 is formed in a convex shape, the cover material 3 is attached to the non-convex portion to support it. The width of the surface can be the same as the width of the support surface that supports the ceiling material 2 with the convex portion, and can be supported uniformly.

  Since the narrow first edge 10 is horizontally arranged to support the ceiling material 2 and the gap between the end of the ceiling material 2 and the wall material 1 is about 15 mm, the wall material 1 When the surface is formed in a flat shape, or when a part of the surface of the wall material 1 is formed in a convex shape, an appropriate gap that can cope with an earthquake is secured by arranging the convex portion. The

  Further, when connecting the two cover members 3, the two cover members 3 to be connected to the dovetail grooves 12 formed on the inner surfaces of the first edge 10 and the second edge 11 of the cover member 3. Since the connecting plate 17 can use both the dovetail groove 12 of the first edge 10 and the dovetail groove 12 of the second edge 11, the connecting plate 17 can be used in various ways for the cover material 3 and the connecting plate 17. There is no need to produce a mold having dimensions, and the cost can be reduced.

  In this case, since the two cover members 3 can be connected by inserting the connecting plate 17 into the dovetail groove 12 of both cover members 3, the design is good.
