(Locking portion for supporting member) is formed to protrude. This Kasagi holder 1 is fixed by screwing fixed pieces 1a onto the roof frame a at regular intervals, and at this time, the upright piece 1c is close to the other roof frame a of the roof frame a. The locking piece 1d protrudes laterally on the far side with respect to the other roof frame a. Next, the cap 2 is a long member, and includes a raised part 2b (locking part for supporting member) at one end of a central cover part 2a, and a lowered part 2 at the other end.
A bent locking portion 13 having a locking groove 13a is formed at the upper end of the raised portion 2b, whereas a bent portion 14 is formed at the lower end of the raised portion 2c. A locking concave and convex strip 15 is carved on the inside of the lower end. Then, the Kasagi 2 locks the locking groove 13a at the upper end of the upright portion 2b to the upper end swollen portion 11 of the upright piece 1c of the Kasagi holder 1, while the lower bent portion 14 of the lower end portion 2c of the Kasagi holder 1. It is locked and fixed to the Kasagi holder 1 by being locked to the lower end of the locking piece 1d. At this time, even if there is a gap between the bent portion 14 and the locking piece 1d due to a dimensional error, the matching portion of the locking uneven strip 15 inside the lower end of the vertical portion 2c and the locking piece 1d can be locked, and the proper locked state of both can be maintained.

On the other hand, the support member 3 is a long member, and a locking groove 13b is formed on the side of the horizontal member 17b at the upper part of the support piece 3a, which is formed by bending the vertical member 17a and the horizontal member 17b into an L shape.
is formed to open downward, and protrusions 16a and 16b protrude from the upper bottom and opening of the locking groove 3b, respectively. Further, an airtight material fitting groove 19 is formed on the upper end of the support piece 3a on the side of the locking groove 3b, and a locking bent portion 20 is provided on the opposite side. Further, a convex locking portion 3c projects from the lower portion of the vertical member 17a on the side of the locking groove 3b, and a water stop plate fitting groove 21 is formed on the opposite side.

In this case, since the support member 73 and the cap 72 can be attached at the same time, work efficiency is further improved. The cap 72 and the support member 73 are brought into contact with each other through engagement of the outer surface of the raised portion 72b (preferably the uneven portion 89) and the protrusions 84a and 84b of the locking groove 73b, and the bent end portion 72e The large and small locking uneven strips 85a and 85b lock together, and the above-mentioned locking and locking are strengthened by the bending elasticity of the bent portion 72d, so that both members 72 and 73 are not locked. There is no. Also, due to the bending elasticity of the bent portion 72d, the protrusions 84a, 84b and the raised portion 72b
Since it is in closer contact with the rain, it is better to keep out the rain. As in the previous example, the intrusion of wind and rain due to the blowing pressure and capillary action can also be effectively prevented.

The attachment of the joint holder 74 to the support member 73, the attachment of the expansion joint cover 75 to the joint holder 74, and the fitting of the waterstop plate 26 are the same as in the example shown in FIG. 1 above. be. The other building structure (not shown) may be a roof structure such as a parapet similar to that shown in FIG. 1, but of course may also be a wall frame or the like. When it is a wall structure, the support members, expansion joint covers, etc. may be constructed as illustrated in FIGS. 2 and 3.

FIG. 6 shows still another example in which the support member and the cap are directly engaged. In the figure, E indicates an expansion joint. In this expansion joint E, a Kasagi 92 is placed on a Kasagi holder 91 fixed on a building structure a.
At the same time, the supporting member 93 is locked to the Kasagi holder 91 on one side and to the Kasagi 92 on the other side. is provided with a locking piece 91c, and the locking piece 9
A locking protrusion 91e and a convex locking part 91f (locking part for supporting member) are formed at the upper and lower ends of 1b, respectively, and it is fixed on the roof frame a by screwing the fixing piece 91a. There is. The cap 92 has a raised part 92b at one end of the cover part 92a and a lowered part 92c at the other end, and a locking groove 92d is formed at the base of the raised part 92b. Standing part 92
b and the structure of the falling portion 92c are the same as the example shown in FIG. The Kasagi 92 is fixed to the Kasagi holder 91 by locking the vertical portion 92c to the locking piece 91c and locking the locking groove 92d at the base of the raised portion to the locking protrusion 91e. ing.

On the other hand, the support member 93 has the same structure as that shown in FIG.
3 (locking part for support member), and on the other hand, by locking the locking part 106 at the tip of the horizontal member 93b to the locking part 91f of the Kasagi holder 91, it is fixed on the roof frame a. ing. However, in this case, the locking groove 93a locks the raised portion 92b of the cap 92 which has been locked and fixed on the cap holder 91 in advance. Since the cap 92 is fixed on the roof frame a together with the cap holder 91, the attachment of the support member 93 that is locked and fixed to the cap holder 91 and the cap 92 is stable. The effect of the engagement between the cap 92 and the support member 93 is similar to that shown in the example of FIG.

As explained in detail above, the present invention has a device configuration in which the support member of the expansion joint is locked to the Kasagi holder on one side, and the other side is locked and fixed to the Kasagi. It can be easily fixed on the roof frame without the need for fixing or caulking, greatly improving work efficiency. Further, since the support member and the cap are sufficiently tightly and elastically fitted and locked, the support member is stably fixed and reliable construction can be achieved. Further, since the cap is long and elastically fits into the support member, which is also long, as described above, the cap and the support member are in close contact with each other, so that rain protection is good.
