[Embodiment] The roof plate 6 uses a metal plate that has been subjected to rust prevention treatment such as a color coated steel plate, and the roof plate 6 is long in the eaves direction from the ridge to the eaves. And
An inclined piece 15 is formed at the end of the roof plate 6 so as to incline downward toward the outside, and a rising piece 16 is raised obliquely upward from the lower end of the inclined piece 14, and these inclined pieces 15 and the rising pieces are formed. 16 and 16 form substantially V-shaped connecting pieces 7, 7. Such roof plates 6 and 6 are connected in a direction substantially orthogonal to the eaves ridge direction. Hereinafter, the connection structure will be described in detail.

The connection drainage member 2 has a substantially U-shaped cross section and is elongated over substantially the entire length of the roof toward the eaves.
Is formed over the entire length, and further, the locking pieces 3, 3 are extended substantially horizontally from the upper edge portions on both sides toward the inside. For example, an iron plate subjected to anticorrosion treatment is roll-formed. is there. The connection drainage member 2 is attached to the roof substrate 10 such as a purlin at a pitch of about 600 mm to 900 mm. The ridge-side end of the connection drainage member 4 is fixed to the roof substrate 10 on the ridge side with bolts (not shown), and in the middle of the connection drainage member 4, the roof substrate 10 is bolted to the roof substrate 10. It is pressed by the fixed press fitting 13 so that thermal expansion and contraction in the eaves ridge direction can be permitted.

The receiving seat 4 is substantially U-shaped and can be horizontally rotated in the drain groove 1 with a length smaller than the groove width of the drain groove 1 of the connection drain member 2. Receiving pieces 5 and 5 are formed at both ends of the receiving seat 4. The receiving piece 5 is formed by bending a series of small pieces 5a formed on the receiving seat 4, but the shape and form of the receiving piece 5 can be changed in various ways. The pressing body 8 is
It is composed of a pressing member 18 that presses the roof plate 6 and a cover locking member 19 that locks the connecting portion cover 9. The pressing member 18 and the cover locking member 19 are both connected drainage members 2
The width is smaller than the groove width of the. Substantially V-shaped pressing pieces 8 a for pressing the connecting piece 7 are bent and hung on both sides of the pressing material 18. A substantially C-shaped cover locking piece 8b that locks the connecting portion cover 9 is bent and erected on both sides of the cover locking member 19. A through hole 8c is formed in the pressing member 18 and the cover locking member 19.

Adiabatic strength made of a material having high heat insulation and pressure resistance, such as wood wool cement or wood chip cement, on both sides of the connecting drainage member 2 fixed to the roof substrate 10 with the pressing metal 13 and bolts. The member 20 is placed and fixed to the roof substrate 10 with self-drilling screws or the like. The roof plates 6 and 6 are placed on the heat insulating strength members 20 and 20, and the roof plates 6 and 6 are connected as follows.

As shown in FIG. 2B, the connection drainage member 2
Of the roof plates 6, 6 to be connected by rotating the receiving seat 4 horizontally in the drainage groove 1 of the above so that the receiving pieces 5, 5 at both ends are located on the lower surface of the locking pieces 3, 3 of the connecting drainage member 2. The connecting pieces 7, 7 are placed on the receiving seat 4, and the cover locking member 19 serving as the pressing body 8 is placed.
And the fixture 12 which is a bolt in the through hole 8c of the pressing member 18.
Through, and screwing into the lower hole of the seat 4 while forming a screw hole to fix the pressing member 18 and the cover locking member 19 to the seat 4, and thus the connecting piece 7 And pressing material 1
Hold tightly with 8. In this case, the receiving seat 4 is pulled up by screwing in the fixing tool 12, and the receiving seat 4 floats from the bottom surface of the connection drainage member 2. Next, the connecting portion cover 9 is pushed between the roof plates 6 and 6, and the lower end of the connecting portion cover 9 is locked to the cover locking piece 8b of the cover locking member 19.

As described above, the roof plate mounting portions 5A and 5A are not erected on the connection drainage member 2 as in the conventional case, and the drainage function of the connection drainage member 2 is not deteriorated. The cost can be reduced as compared with the aluminum extruded product while obtaining the drainage property. By the way, the receiving seat 4 can be easily installed at an arbitrary position of the long connection drainage member 2, and the workability is enhanced.

At the tip of the pressing metal fitting 13, a rotation stopping piece 1 is provided.
3a is hung down to form a guide rail, and the receiving seat 4 is moved in the length direction of the connection drainage member 2 to allow the receiving piece 5 to enter, so that the rotation stop of the receiving seat 4 is reliably prevented. . In this case, the notch 13b is formed in the rotation stopping piece 13a, and the receiving piece 5 portion of the receiving seat 4 is inserted into the notch 13b.
The catch 4 is prevented from rotating. And
As shown in FIG. 4 (b), the detent pieces 13a may be left only on the eaves side. As described above, the shapes and shapes of the press fitting 13 and the anti-rotation piece 13a can be changed in various ways.

FIG. 4 shows another embodiment of the pressing body 8, in which the pressing member 18 and the cover locking member 1 in the above embodiment are used.
9 and 9 are integrated. In this way, the pressing body 8
The shape and form of can be variously modified.

[0018]

According to the first aspect of the present invention, unlike the conventional case, the roof plate mounting portion is not erected on the connection drainage member,
The drainage function of the connection drainage member is not deteriorated and the drainage function of the connection drainage member can be simplified while the drainage function of the connection drainage member can be simplified. Cost can be reduced compared to products, and
To connect the connection drainage members in the groove length direction, they can be stacked exactly using the elastic deformability of the sheet metal connection drainage members, water tightness can be easily ensured, and both sides of the connection drainage members can be secured. Locking pieces extend inwardly from the upper edge towards the inside, and with a length smaller than the width of the drainage groove, a receiving piece is formed at both ends of the seat that can be horizontally rotated in the drainage groove. Therefore, the receiving seat is horizontally rotated in the drainage groove of the connection drainage member so that the receiving pieces at both ends are located on the lower surface of the locking piece of the connection drainage member. There is an advantage that it can be easily installed at any position and the workability can be improved.

In the second aspect, since the receiving seat is floated from the groove bottom of the connection drainage member, there is an advantage that it is possible to avoid deterioration of the drainage function due to the receiving seat inserted into the connection drainage member. In the third aspect of the present invention, the receiving seat is locked by a metal fitting for fixing the connection drainage member to the roof substrate and is prevented from rotating. Therefore, the receiving seat can be positioned to be horizontally rotated in the connection drainage member. There is an advantage that the property can be enhanced.

According to the present invention, since the notch is formed in the pressing member and the receiving seat is inserted and locked in the notch, it is possible to reliably prevent the receiving seat from being prevented from rotating. There is an advantage that the arrangement position of can be maintained for a long period of time. According to the present invention, since the receiving seat is arranged at a position other than the holding metal fitting, the receiving seat can be easily installed at an arbitrary position of the long connecting drainage member, and the roof by the receiving seat is provided between the holding metal fittings. There is an advantage that the plate can be supported.
