Abut. With this, for the holder intermediate material 9
The tip 12 of the holder is not stubborn and the holder member 8 and cover
Even if the bar 3 moves, the cover 3 is suddenly removed from the holder member 8.
It can be prevented from coming off.

Further, a locking piece portion 5 of the base end portion 4 of the cover 3
And the first locking piece portion 14 of the holder base end material 11 of the holder member 8 constitutes the engaging mechanism B. Further, the engagement mechanism C is constituted by the engagement piece portion 7 of the tip end portion 6 of the cover 3 and the tip end portion 40 of the engagement oblique piece 17 of the holder tip end material 12 of the holder member 8.

Then, the cover 3 is attached by the engaging mechanism B.
The holder base end material 11 of the holder member 8
The first locking piece 14 of is locked. Furthermore, by utilizing the elastic deformation of the cover 3, the engaging mechanism C engages the engaging piece 7 of the cover 3 with the tip 40 of the holder tip member 12 of the holder member 8.

A cushioning material 22 is fitted in the dovetail groove 20 of the holder tip member 12 and is elastically applied to the back surface of the cover 3 to prevent rattling and noise. To do. Thus, the cover / holder unit body 21 including the cover 3 and the holder member 8 is formed.

In this engaged state, however, the upper surface of the holder intermediate member 9 approaches or abuts the rear surface of the cover 3 over the entire length. Therefore, the rigidity and strength of the cover 3 are increased.

Next, a wall-mounting edge member 23 is attached to the vertical outer wall V.
Are fixed, and the holder base end material 11 of the holder member 8 of the unit body 21 and the wall mounting edge material 23 are engaged with each other through the holding and holding hinge mechanism 11, and the unit body 2
1 is connected around the holding mechanism H of the outer wall V so as to be vertically swingable as indicated by an arrow E.

Specifically, the wall-mounting edge member 23 includes the base portion 2.
5, the receiving and supporting piece 24 is horizontally projected from the upper and lower intermediate portions, and the base 25 is provided at a position slightly above the receiving and supporting piece 24.
The locking piece portion 26 that bends downward from is projected, and the width dimension (projection length) of the locking piece portion 26 is set to be smaller than that of the receiving and supporting piece 24.

The embracing hinge mechanism H has the holder base that engages in the recessed groove formed by the receiving and supporting piece 24 and the locking piece 26 of the edge member 23, and both of them in this way. The second locking piece portion 15 of the end material 11 is included.

However, in FIG. 1 and FIG. 2, Z is added to the frame R.
The character-shaped bracket 27 is fixed. This bracket 27
Has a projecting support portion 29 projecting upward from the horizontal upper side portion 28, and a connecting rod hole portion 30 penetrating as a so-called stupid hole. The bracket 27 is fixed to the frame R with bolts 31.

Further, the holder members 8 arranged at predetermined intervals in the longitudinal direction of the cover 3 are attached in the direction orthogonal to the cover 3, but the elastic locking members 3 such as a cap-shaped leaf spring material.
2 is locked to the holder intermediate material 9 made of the extrusion mold material M.

That is, as shown in FIG. 2, the elastic locking member 32 is accommodated in the lower opening dovetail groove 33 of the holder intermediate member 9, and is locked by the lower end pieces 34, 34 to elastically urge downward. To do. Then, a connecting rod 35 such as a bolt is continuously provided so as to project downward from the elastic locking member 32, and the connecting rod 35 is inserted into the connecting rod hole portion 30 of the bracket 27 so as to swing freely. The nut holder 37 is screwed on and the holder intermediate member 9 is attached to the bracket 27.

That is, the mounting member 42 is a bracket.
27, the elastic locking member 32, the connecting rod 35, and the washer 36.
It has a nut 37 and the mounting member 42 (see FIG.
The holder member 8 is attached so as to swing freely in the directions represented by arrows G and K. Moreover, the elastic locking member 32 only abuts on the inner surface of the lower end pieces 34, 34 of the holder intermediate member 9, and is slidable as shown by arrows N, P.

The water stop plate 38 is stretched under the cover 3 over substantially the entire width thereof. Specifically,
The upper end surface 41 of the body R and the gap 2 are covered with a water blocking plate 38.
And the front end portion 38b of the water blocking plate 38 is
Through the 39, the water stop plate fixing projection piece 1 of the holder tip member 12
It is fastened to 9,19 . The base end 38a of the water stop plate 38 is fixed to the outer wall V by the edge member 23, and the middle portion is a frame R.
Coated on the upper surface of Ru is fixed by the bracket 27. Well
In addition, the edging material 39 is formed by the protruding pieces 19, 19 on the back surface of the locking oblique piece 17.
Then, it is detachably pressed and fixed. This edge member 39 is long. As a result, the frame R and the tip of the cover 3 are
It is possible to prevent rainwater and the like from entering between

Next, FIG. 3 shows an expansion joint of another embodiment, and illustrates the case where the expansion joint is provided in the space 2 between the roofs.
In this embodiment, considering that the portion indicated by the arrow [Q-Q] in FIG. 1 is approximately doubled to the left-right symmetrical shape, the detailed description given above is valid as it is, and the same reference numerals are the same. It is the structure of.

That is, in this embodiment, the locking pieces 7, 7 are formed on both edges of the cover 3, and the holder member 8 is also provided.
Is a holder intermediate material 9 and holder tip materials 1 at both ends thereof.
2 and 12. The tip 40 of the holder tip member 12 is locked to each locking piece 7.

In FIG. 3, the holder intermediate member 9 of the holder member 8 is bent upward in the center, and correspondingly, the cover 3 is slightly bent with the center protruding upward. ing.

The water stop plate 38 is stretched over substantially the entire cover 3, and is provided between the locking oblique piece 17 and the frame R, and the frame R,
It is stretched between R with a bend.

The present invention is not limited to the above-described embodiment, and the design can be freely changed without departing from the gist of the present invention.
For example, it is also preferable that the dovetail groove 20 is not formed in the holder tip member 12 and that the buffer member 22 is not provided.
