【Example】

The present invention will be explained in detail below based on drawings showing embodiments.

[0008] Figure 1 shows an expansion joint according to the present invention, with one frame A (vertical part of the outer wall) and the other The gap 1 between it and the frame B (corner part of the outer wall) is covered and isolated from above. , the decorative cover material 2 includes a receiving plate material 3 made of stainless steel or the like, and a decorative board 4 such as a tile on the top surface... and a filler 5 such as mortar for pasting this, and the decorative cover material 2 is A reinforcing member 6 made of stainless steel or the like is fixed to the back surface by welding or the like.

[0009] Then, on one end (body A side) of the reinforcing member 6 having an inverted concave cross section, A stepped portion 7 is formed on the surface, and an extruded aluminum material is placed between the decorative cover material 2 and the stepped portion 7. A holding member 8 consisting of the following components is clamped using fixing tools 9.

0010 The holding member 8 is bent into a substantially Z-shape along one end surface of the reinforcing member 6, and the tip thereof is bent. It has a locking piece 10 formed in a substantially J-shape.

[0011] A receiving member 11 made of an extruded aluminum material is fixed along the corner C of the frame A. An inverted U-shaped locking piece 12 whose upper portion is curved downward; and the locking piece 10. are engaged and received by the horizontal support piece 13 of the receiving member 11.

0012 In this way, the locking piece part 10, the locking piece part 12, and the receiving support are provided on one edge side of the decorative cover material 2. Together with the piece 13, the hinge mechanism 14 is composed of the decorative cover material 2, the reinforcing member 6, etc. The joint body 15 is made swingable around the hinge mechanism 14 by a predetermined angle as shown by arrow D. ing.

[0013] In addition, a strip-shaped edge made of stainless steel or the like is provided on one side of the decorative cover material 2 (body A side). The material 16 is fixed by welding, etc., and the gap between the frame A and the edge material 16 is filled with a sealing material 17. At the same time as filling, the back surface of the other side edge of the decorative cover material 2 is filled at a predetermined angle---for example, A stainless steel having a guided slope surface 18 that slopes from above to inward and downward at 30° to 60°. A band-like edge material 19 made of resin or the like is fixed.

[0014] Furthermore, it has a guiding slope surface 20 having substantially the same angle as the guided slope surface 18, and , a horizontal slide that slidably receives the reinforcing member 6 (indirectly or directly). A parting member 22 having a surface 21 is attached to the corner E of the frame B, and the guide slope surface 20 and the guided The sloped surface 18 is fixed in close proximity with a predetermined distance G.

[0015] More specifically, in FIG. 1, the reinforcing member 6 is slidable via the vertical adjustment screw 31. The lower surface of the reinforcing member 6 and the sliding surface 21 are received by the surface 21 and are connected to each other through an adjustable gap 32. are facing each other. 33 is a nut welded to the back side of the reinforcing member 6; The above-mentioned vertical adjustment screw 31 is screwed into the nut 33 so as to be able to move up and down. In addition, the decorative board Drill a hole for the driver and close it with a decorative bolt.

[0016] Therefore, the joint main body 15 and the frame B to which the parting material 22 is fixed are aligned with each other in the F direction. It becomes possible to move relative to the other.

[0017] Then, the hinge mechanism 14 approaches or comes into contact with the guided slope surface 18 of the edge material 19. By providing the guiding slope surface 20, the gap 1 between both frames A and B is Even if the joint body 15 increases or decreases significantly, the joint body 15 will not come off from the body B and will remain within the above specified range. Even if the displacement exceeds the gap G (in the direction in which the gap 1 between both bodies A and B narrows), the guided The guiding slope surface 20 rides on the horizontal slope surface 18, and the joint body 15 moves diagonally upward (in the H direction). It is possible to follow the movements and fluctuations.

[0018] In addition, even if both bodies A and B are vertically shifted relative to each other, the hinge mechanism 14 allows the joint to The main body 15 can oscillate to follow fluctuations, and can also be rotated in a direction orthogonal to the drawing in FIG. Even if both bodies A and B are shifted relative to each other, the receiving support piece 13 and the locking piece 10 of the hinge mechanism 14 Since the sliding surface 21 of the parting member 22 and the back surface of the reinforcing member 6 are slidable, the joint body 15 is variable. can follow.

[0019] By the way, a nut 23 is fixed to the back surface of the reinforcing member 6, and a decorative member is attached to the nut 23. The eye bolt for cover removal can be screwed onto the top surface of the decorative cover material 2. A hole is provided in the cover material 2, and the hole can be covered with a decorative bolt or the like. It is.

[0020] In addition, as shown in Figure 2 which shows the lower part of Figure 1, there is a stainless steel plate underneath the expansion joint. Attach the hanging drain plates 24, 24, etc. along the corresponding surfaces for forming the gap of both the bodies A, B, A bucket holder 25 made of stainless steel or the like is provided at the lower end of the hanging drain plates 24, 24, and , a fireproof belt 26 is provided below the bucket support 25.

[0021] Therefore, even if water infiltrates through the gap between the expansion joints, the hanging drain plates 24, 24 Since the fireproof zone 26 can be drained by falling into the bucket receiver 25, the fireproof belt 26 will not get wet.

[0022] Note that the present invention is not limited to the above-mentioned embodiments, and may be modified without departing from the gist of the present invention. Design changes are free.

[0023] For example, in FIG. 1, the increase or decrease in the inclination angle of the guided slope surface 18 and the guiding slope surface 20 is Be free.
