DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a first embodiment, in which roof plate members 3a and 3b formed of a metal plate such as a color iron plate are connected to ends on the connection side. An inclined standing piece 10 that is inclined is formed. The upper portions of the inclined standing pieces 10 are outwardly bent substantially horizontally to form horizontal pressed portions 5, 5. A substantially inverted U-shaped water return portion 12 is formed at the tip of the horizontal pressed portion 5. Roof 3a, 3
b is long in the eaves ridge direction and has a length of about 20 to 30 m, and a width orthogonal to the eaves ridge direction is about 400 mm. The roof slats 3a and 3b are fixed to the ridge at the upper ends thereof with bolts and the like, and are connected to the tight frames 1a and the connection fittings 6 at the intermediate portions by a connection fitting 6 described later.
To allow thermal expansion and contraction of the roof slats 3a, 3b.

FIG. 3 shows the connection fitting 6, which is short in the direction of the eaves ridge. The connection fitting 6 in this embodiment includes a receiving fitting 6a and a holding fitting 6b. The holding metal 6b is formed by bending a metal strip.
A central portion is raised, and a through hole 13 is formed in the central portion. A cut-and-raised piece is formed at the center of the holding metal member 6b and bent in a substantially inverted U-shape. The lower end of the holding metal piece 6b is an inclined holding section 11, and the lower horizontal piece of the inclined holding section 11 is a cap engaging section 25. It is. Horizontal holding portions 7 are formed on both sides of the inclined holding portion 11. The bracket 6a is approximately U
It is formed in the shape of a letter, a hole 15 is formed, and a cutout 14 is formed in both leg pieces so that it can be engaged with the tight frame 1a serving as the roof foundation 1. The tight frame 1a is fixed to the purlin by welding (not shown) or the like, and a fixing member 8 such as a bolt is fixed to the tight frame 1a by welding or caulking, and the fixing member 8 is provided with a receiving member. The hole 15 of 6a is inserted, and the notch 14 of the metal fitting 6a is engaged with the tight frame 1a. The horizontally pressed portions 5 at both ends of the roof plate members 3a and 3b are placed on the tight frame 1a, and the inverted U-shaped water return portion 1 is provided.
2 is in contact with the metal fitting 6a, and both roof plate members 3a, 3
b is positioned, and the interval between the roof slats 3a, 3b is determined. Thereafter, the through-hole 13 of the holding member 6b is inserted into the fixture 8, the nut 16 is screwed, and the horizontal holding portion 7 is located above the horizontal holding portion 5 of the roof plate members 3a, 3b with a slight gap. You. In this case, the inclined holding part 11 is located substantially vertically outward with a slight gap from the inclined holding part 11 of the roof slats 3a, 3b. Next, the arc-shaped cap 9 is covered and received by the cap support surface 17 formed on the inclined holding portion 11, and the pressed portion 26 is moved to the cap engaging portion 25 by utilizing the elastic restoring force of the cap 9. And the cap 9 is elastically held. In this case, the pressing part 27 is the inclined standing piece 1
It is in elastic contact with the outer surface of 0.

In this manner, the roof plate 3
a, 3b by pressing the substantially letter-shaped portions,
The floating of a and 3b can be effectively suppressed. Moreover, the cap 9 is pressed by the cap engaging portion 25 of the connection fitting 6, and the inclined standing piece 10 is also pressed by the pressing portion 27 of the cap 9, so that rainwater infiltrates the connection portion along the roof plate members 3 a and 3 b. And to improve watertightness.

In this case, in the construction state, the horizontal pressing portion 7 has a slight gap formed with respect to the horizontal pressed portion 5, and the inclined pressing portion 11 includes the inclined standing piece 10.
A slight gap is formed between the roof panels 3a and 3b to prevent the rust from being generated by damaging the coating of the roof slabs 3a and 3b. The plate members 3a and 3b are prevented from floating under negative pressure.

Incidentally, a long closing plate 28 is covered at the connection portion between the roof plate members 3a and 3b. That is, as shown in FIG. 4, a long blocking plate 28 is placed on a bolt serving as the fixture 8, the pipe 18 is placed, and the pipe 18 is placed with a hammer.
Then, the long closing plate 28 is driven into the bolt, and the pipe 18 is pulled out. The long closing plate 28 that has been driven in is straddled across the water return portions 12, 12 at the tips of the horizontal pressed portions 5 of the roof plate members 3a, 3b, and the long closing plate 28 is used to cover the roof plate members 3a, 3b. Is covered over the entire length thereof, thereby preventing the outside, for example, cold air from entering, or preventing, for example, the warm air from escaping from the inside at the connection points, thereby making the connection points sufficiently airtight. As a result, it is possible to avoid dew condensation on the back surface of the cap 9, and prevent rainwater rising from the inclined standing piece 10 along the horizontal pressed part 5 and the water return part 12 from entering the connection part of the roof plate members 3a, 3b. It is possible to increase the watertightness of the connection between the roof slats 3a and 3b.

FIG. 5 shows another embodiment, in which a connection fitting 6 is formed by forming the above-mentioned receiving fitting 6a and the above-mentioned holding fitting 6b in series. Further, a pressed portion 26 is formed at an intermediate portion of the cap 9 so that the square cap 9 can be engaged and held. In this case, since the gap d between the upper end surface of the water return portion 12 of the roof plate members 3a and 3b and the cap 9 is narrow, the air permeability at this location can be suppressed, and the closing plate 28 is not used. Other configurations are the same as those of the above-described embodiment.

[0014]

According to the first aspect of the present invention, an inclined standing piece which is inclined outward is formed at an end of the roof sheet material on the connection side, and the upper end of the inclined standing piece is bent outward and substantially horizontally to horizontally cover the inclined standing piece. Since the holding part is formed and the connecting fitting is formed with the horizontal holding part that holds the horizontal pressed part of the roof plate material and the inclined holding part that holds the inclined standing piece, the connection fixed to the roof foundation with the fixture The horizontal holding part of the metal fitting can hold the horizontal pressed part of the roof sheet material, and the inclined holding part can hold the inclined upright piece, and thus hold the substantially salient portions of both ends of the roof sheet material. Thus, there is an advantage that the floating of the roof slab can be effectively suppressed. Moreover, it is possible to hold down the inclined standing piece by the pressing portion of the cap which is locked and held by the connection fitting, to prevent rainwater from penetrating the roof plate material and entering the connection location, and to improve the water tightness of the connection location. There is an advantage that the workability can be improved as compared with the conventional seam folding work.

According to the second aspect of the present invention, the water return portion is erected at the end of the horizontal pressed portion of the roof plate material, and the long cover plate is erected across the water return portion. It covers the connection point of the roof slab material over the entire length, and it is possible to prevent the outside, for example, cold air from entering, or to prevent, for example, the warm air from escaping from the inside at the connection point, and to make the connection point airtight enough. By doing so, it is possible to prevent condensation from forming on the back surface of the cap, and it is possible to prevent rainwater flowing from the inclined standing piece along the horizontal pressed part and the water return part from entering the connection part of the roof sheet material, and connecting the roof sheet material. There is an advantage that the watertightness of the portion can be improved.
