An overhang 4 provided along the upper edge of the other joint end face 2a of the other roof panel 2.

The one roof panel 1 has a base material 6 and a base plate 7a attached to the upper surface of a rectangular frame 5. The base plate 7a has a notch 7c formed in a portion corresponding to the upper edge of the one joint end surface 1a. A gap t2 is formed between the base material 6 and the base plate 7a. The other roof panel 2 has a base material 6 and a field board 7b attached to the upper surface of a square frame 5. Base material 6 and base plate 7
A gap t3 is formed between b.

As shown in FIGS. 2 and 4, the watertight fitting 3 is formed by bending a long thin steel plate to form a mounting piece 8 extending along the upper surface of the base material 6 of the one roof panel 1. And an elastic piece 9 rising from the upper surface of the mounting piece 8 so as to incline above the one joint end face 1a, and a downward groove-shaped support piece 10 extending from the tip of the elastic piece 9; Furthermore, while providing the packing material 11 on the upper surface of the support piece 10,
A plurality of elevating pieces 12 made of a rectangular thin steel plate are connected to the tip of the elastic piece 9 at regular intervals. The elevating piece 12 extends along the other joint end surface 2a and has a lower end 12
a is hung down along the one joining end surface 1a.

The mounting piece 8 is fitted in the gap t2, and forms a plurality of elongated holes 8a extending in the width direction of the one roof panel 1 at equal intervals in the longitudinal direction. 8a, the one roof panel 1
The base material 6 is attached so as to be able to advance and retreat inside the one other joining surface 1a. The packing material 11 is formed by shaping a foamed resin into a square rod shape extending over the entire region of the watertight fitting 3 in the longitudinal direction. The elevating piece 12 forms an elongated hole 12b extending in the vertical direction, and is attached to one joint end surface 1a of the one roof panel 1 so as to be vertically movable by a nail b penetrating the elongated hole 12b. . The lower end 1
A hook hole 12c is formed in 2a, and a mark 12d is provided on the surface of the lower end portion 12a by giving a color different from that of the pair of roof panels 1 and 2.

As shown in FIGS. 3 and 4, the overhang fitting 4 is formed by bending a thin steel plate to form a fixing piece 13 extending along the upper surface of the base material 6 of the other roof panel 2.
And a downward groove-shaped pressing piece 14 projecting from the upper edge of the one joint end surface 1a to the one roof panel 1 side. The fixing piece 13 is fitted in the gap t3, a plurality of through holes 13a are formed at regular intervals in the longitudinal direction, and a nail c that penetrates these through holes 13a is formed.
Thus, it is fixed to the base material 6 of the other roof panel 2.

The procedure for joining the pair of roof panels 1 and 2 will be described below. First, as shown in FIG. 4, the one roof panel 1 is installed at a predetermined position, and then, the pressing piece 14 of the overhang metal fitting 4 together with the other roof panel 2 from directly above one joint end surface 1 a. Descend. Then, by placing the pressing piece 14 on the packing material 11 of the watertight fitting 3, as shown in FIG.
Is elastically deformed downward, the entire elevating piece 12 descends, and the lower end portion 12a projects below the other roof panel 2.

On the other hand, as the elastic piece 9 elastically deforms downward, the mounting piece 8 receives the reaction force of the elastic piece 9 to move the inside of the gap t2 inward of the one joint end face 1a. Therefore, the elevating piece 12 is not pressed in a direction away from the one joint end face 1a by the reaction force of the elastic piece 12. Therefore, the lifting piece 1
The frictional resistance between the elevating piece 12 and the nail b can be minimized when the 2 descends.

In this case, since the mark 12d is provided on the lower end portion 12a as described above, it is easy to visually confirm that the lower end portion 12a of the lifting piece 12 projects below the roof panels 1 and 2. Can be. Further, since the shape of the support piece 10 of the watertight fitting 3 and the shape of the pressing piece 14 of the overhang fitting 4 are respectively downwardly grooved, the supporting piece 10 and the pressing piece 14 are completely pressed by the load of the other roof panel 2. The overhang 4 is positioned at a predetermined height by the support piece 10 and the pressing piece 14 as shown in FIG. 1 without being crushed.

Even when the pressing piece 14 is lifted by the elastic force of the elastic piece 9, the hook 12 is hooked into a hook hole 12c at the lower end 12a of the lifting piece 12, and the lifting piece 12 is moved. By pulling downward, the elastic piece 9 is forcibly elastically deformed downward, whereby the upper surface of the pressing piece 14 can be flush with the one roof panel 1. Therefore, it is not necessary for an operator or the like to climb on the pair of roof panels 1 and 2 installed on the hut assembly, so that the construction can be performed safely.

Further, the lower end 12a of the lifting piece 12 is
The other roof panel 2 is bent along the lower surface of the rectangular frame 5. In this case, the lifting piece 12 can be bent at a vertical position corresponding to the lower surface of the rectangular frame 5 of the other roof panel 2, so that the lower end portion 12 of the lifting piece 12 can be bent.
A gap does not open between a and the lower surface of the rectangular frame 5 of the other roof panel 2. For this reason, regardless of the thickness dimension of the other roof panel 2, the pair of roof panels 1, 2
Can be reliably connected. Finally, the nail d is inserted into the hook hole 12c.
And the lower end portion 12a of the elevating piece 12 is fixed to the other roof panel 2 by striking the lower surface of the rectangular frame 5 of the other roof panel 2.

In the above embodiment, a single hooking hole 12c is formed at the lower end 12a of the lifting piece 12, but the number, size and shape of the hooking holes 12c are not particularly limited. Further, the elevating piece 12 may be a single steel plate extending along the upper edge of the joint end surface 1a of the one roof panel 1.

According to the first aspect of the present invention, when the pressing piece rises due to the elastic force of the elastic piece, the lower end of the lifting piece is pulled downward to force the elastic piece downward. Since the pressing piece can be pulled down by being elastically deformed, it is not necessary to press the other roof panel from above. In addition, since the lower end of the elevating piece is bent and fixed along the lower surface of the other roof panel, the work of connecting the pair of roof panels can be performed from below these roof panels. Therefore, there is no need for the worker or the like to climb the hut as in the related art, and the construction can be performed safely. Further, a scaffold for the worker to work at a high place is not required, and the number of construction steps can be greatly reduced.

Further, since there is no need for a connecting tool for connecting a pair of roof panels, the number of parts is small and the construction is easy. Also, since the lifting piece can be bent at the vertical height position corresponding to the lower surface of the other roof panel, no gap is opened between the lower end of the lifting piece and the lower surface of the other roof panel, The pair of roof panels can be securely connected.

According to the joint structure of the roof panel, when the packing material is pressed by the pressing piece to elastically deform the elastic piece downward, the mounting piece receives a reaction force of the elastic piece and one of the roofs. Since it moves inward of the joint end face of the panel, the elevating piece is not pressed in a direction away from the joint end face of one roof panel by the reaction force of the elastic piece. For this reason, the frictional resistance when the elevating piece descends can be minimized.

According to the third aspect of the present invention, since the lower end of the lifting piece is colored differently from the pair of roof panels, the lower end of the lifting piece is connected to the lower surface of the other roof panel. It is possible to easily check visually whether or not it is protruding from the device, and to speed up the construction.

According to the joint structure of the roof panel according to the fourth aspect, a hook or the like can be hooked in the hook hole when the lower end of the lifting piece is pulled downward, and the lower end of the lifting piece is connected to the other roof. Since the hook holes can be used as nail holes when fixing to the panel, it can be quickly and easily performed.
