Note that the connecting means of the cover member 54 at each level is the joint 1.
It is almost the same as 1.

Next, in the example shown in FIG. 11, the substrate member 26 constituting the holder member 25 of the joint 22 shown in FIG.
This is an example of saving labor. That is, the holder member 25 of this example consists of a spring member 27, and a substantially U-shaped locking portion 27b with a locking claw 27c formed at the upper part of the center portion 27a of the spring member 27 is attached to the cover member 14. A spring locking portion 14j having an arrowhead-shaped locking protrusion 14i is configured to be elastically locked. That is, the cover member 14 is integrally provided with a spring locking part 14j with a locking protrusion 14i at the center of its base web 14a, and this spring locking part 14j
is vertically installed by being engaged with the engaging portion 27b of the spring member 27. Incidentally, since the configuration of the square is similar to the example shown in FIG. 7, the same reference numerals are given and the explanation thereof will be omitted.

The example shown in FIG. 12 is a modification of the joint 51 shown in FIG. 10 described above. In Figure 10, water conveyance 154r
is formed integrally with the cover member 54, but this twelfth
The figure shows a separate configuration. That is, water conveyance 161d
The cover member 61 constituting the is divided into an inner member 61a and an outer member 61b which are formed in a symmetrical shape, and these members 61a and 61b are fixed with fixing means such as screws or welding at a side edge 61G continuous to the base web. By fixing at 65, a rectangular hollow water guide till 61 d
is formed. Note that the fitting part 61e of the airtight member 20 formed at the end of the cover member 61 is the inner part 06''+a.
A substantially hook-shaped engagement edge 61f that engages with the engagement edge 62a of the support member 62 is formed at the end of the inner member 61a.

Further, in this example, the holder member 64 is made of a spring member, and the same structure as the example shown in FIG. 9 is adopted for attachment to the support members 62 and 63.

That is, the approximately W-shaped holder member 64 is provided with a substantially inverted U-shaped locking portion 64b having locking claws 64a at both ends thereof, and this locking portion 64b is connected to the locking edge 62 of the support member 62, 63.
b, 63b by elastic engagement. Further, a locking portion 64d having a locking claw 64G is formed in the center of the holder member 64, and an arrowhead-shaped locking protrusion 6 provided on the inner member 61a of the cover member 61 is provided on the locking portion 64d.
The cover member 61 is attached by elastically engaging the spring locking portion 61h having a weight of 1g. Note that the other configurations are the same as the example shown in FIG. 10.

Moreover, the example shown in FIG. 13 is an example in which a water guide gutter is attached to the cover member 4 of the example shown in FIG. That is, a water guide gutter 4e having a triangular cross section is integrally provided on the central lower surface of the cover member 4, and water is collected through a hole 4f penetrated through the cover member 4. Further, a spring locking portion 4C having an arrowhead-shaped locking protrusion 4d is provided at the bottom of the water guide t'J 4 e, and this spring locking portion 4C is connected to the locking claw 5d of the holder member 5.
It is elastically secured to a locking portion 5C. Note that the other configurations are the same as the example shown in FIG. 2.

(Effects of the Invention) The present invention is an expansion joint that is installed between the building blocks of adjacent buildings to integrally cover the mutual gap, and in which a support member is attached to the building blocks. At the same time, a holder member is horizontally suspended between the support members, and the holder member has a cover member slidably attached to at least one of the support members, and a water guide gutter for rainwater etc. is connected to the cover member. Another invention provides a structure in which a support member is attached to the frame and the gap is covered.
A holder member connected to the cover member is attached horizontally between the supporting members, and the cover member is slidably attached to at least one of the bamboo support members, and furthermore, the cover member is provided with rainwater. By providing a water guide gutter to cover the gap, it is possible to provide an expansion joint with a water guide gutter that can cope with fluctuations in adjacent structures, and an expansion joint with a water guide gutter attached to shield the gap in the body. The joint can be easily installed. In addition, it has a good aesthetic appearance and is economical because it eliminates the need to install a separate drainage gutter, which is required in the conventional method.
