End rising walls 506 are provided at both edges of the upper surface of the horizontal substrate 500, an intermediate rising wall 507 is provided inside the end rising walls 506, and the end rising walls 506 and the intermediate rising walls are provided. A wide finishing material width adjusting space 503 is formed between the finishing material width adjusting space 503 and the finishing material width adjusting space 503.

The finishing material width adjusting space 503 has a groove shape, supports the daylighting glass frame 4 and forms a drainage groove, and is provided on the lower surface of the connecting member cover 12 at the upper center of the upper connecting member 5. An upper opening 504 into which the insertion support leg 120 is fitted is formed.

To attach the upper connection member 5 to the upper surface of the connection base material 3,
As shown in FIGS. 26 and 27, the insertion hanging piece 501 of the upper connecting member 5 is inserted into the fitting concave portion 302 of the connecting base material 3 to engage the engaging projection 311 and the locking projection 505. , The connection bolt 8 of the connection base material 3, the horizontal substrate 500 of the upper connection member 5 and the upper opening 5

Then, the connection member cover 12 is attached to the upper surface of the upper connection member 5, and the eaves cap 13 is attached to the eaves end portion of the connection member 1.

28 to 31 show a process of attaching the waterproof plate 2 to the connection base material 3, and first, the waterproof plate 4 is inclined as shown in FIG. 28 to utilize the function of the lower side rising wall 200. Then, the waterproof plate storage adjustment space 306 is inserted. Next, as shown in FIG. 29, when the end of the side rising wall 200 on the other side is pressed downward, the side rising wall 200 on the other side slides along the curved outer surface of the sliding curved portion 304. Due to the effect function, it is fitted into the waterproof plate storage adjustment space 306, and the prevention plate 2 becomes horizontal as shown in FIG. Finally, as shown by the arrow in FIG. 31, the waterproof plate 2 is moved laterally to adjust its position.

Of course, the waterproof plate 2 can be attached to the spar 10 even before the connection base material 3 is attached.

The waterproof plate 2 has a width adjusting function capable of standard mounting, positive mounting, and negative mounting with respect to the connection base material 3 in response to an error in the width of the field.

Next, the width adjusting function structure will be described.

As shown in Fig. 33, when the field width is standard 0 adjustment,
The side rising wall 200 of the waterproof plate 2 is inserted into the center of a waterproof plate storage adjustment space 306 formed by a wide gap between the outer sliding curved portion 304 of the connection base material 3 and the inner hanging piece 305. It is installed in the center and becomes a standard installation.

As shown in FIG. 32, when the width of the field is narrower than the standard, the side rising wall 200 of the waterproof plate 2 is used for the minus adjustment when the connection base material 3 is used.
It is inserted close to the hanging piece 305 inside the waterproof plate storage adjustment space 306, and is attached to the inside position to be a minus attachment.

As shown in FIG. 34, the positive adjustment when the field width is wider than the standard is that the side rising wall 200 of the waterproof plate 2 is inserted close to the sliding curved portion 304 of the connection base material 3 and the outside It will be a positive attachment when it is installed in the position.

EFFECTS OF THE INVENTION Since the connection base material of the present invention is provided with the curved sliding curved portion, it is possible to easily store the waterproof plate along the curved surface by simply pressing the side edge of the waterproof plate. Even if rainwater leaks from the upper connecting member, the sliding curved portion serves as a waterproof canopy, and water does not flow from the side edge of the waterproof plate to the back surface.

In addition, since the ridges are provided on the lateral lower surface of the bolt hole, when tightening the nut inserted into the bolt hole, the head of the bolt fits between the ridges and rotation is suppressed, and the bolt is not attached. This is extremely easy, and even when other members such as the upper connecting member are attached to the connecting base material, the holes can be easily aligned by the bolts.

Furthermore, since it has a wide waterproof board storage adjustment space, it can expand due to mounting errors of the connecting base material, manufacturing errors of the waterproof board, and heat.
Even when contraction occurs, these dimensional errors and expansion and contraction can be easily absorbed.
