A second engagement / disengagement portion 25 constituting the other engagement / disengagement means capable of engagement / disengagement with the first engagement / disengagement portion 16 of the receiving member 6 is provided in the groove portion 24. According to the illustrated embodiment, the second engagement / disengagement portion 25 is a deformation hole 26 formed at an interval corresponding to the above-described locking projection 17. The deformation hole 26 has a circular shape having an inner diameter larger than the outer diameter of the locking collar 17a so that the locking collar 17a of the locking projection 17 provided on the receiving member 6 as the first engaging / disengaging portion 16 can pass therethrough. The portion 26a and a long hole portion 26b having a width narrower than the outer diameter of the locking collar portion 17a are communicated with each other so that the locking collar portion 17a can be locked. Protruding part 27 where appropriate parts are projected downward
It is opened in. In other words, since the deformation hole 26 is opened along the slope of the projection 27, it is opened in an inclined manner. Further, a notch 28 is provided on the side of the long hole portion 26b to provide a tongue piece 29.
The tongue piece 29 prevents the supporting member 7 from easily coming off the receiving member 6. That is, since the locking projection 17 is locked to the tongue piece 29, the support member 7 does not move and the locking projection 17 does not come off from the deformation hole 26.

Further, the supporting member 7 has a supporting piece 30 extending laterally from the right and left of the groove 24, and the supporting piece 30 is bent slightly downward and elastically adheres to the upper surface of the side edge of the roofing material 1. Roofing material 1
The roofing material 1 is supported over almost the entire length in the depth direction. The lower edge of the support member 7 is bent downward to provide a superimposing piece 31 capable of superimposing on the locking portion 3 of the roof member 1, and the upper edge corresponds to the block 23 of the receiving member 6 if necessary. Shaped abutment

A notch 35 corresponding to a locking piece 34 of the cover member 8 described later is provided on a side of a lower end portion of the support piece 30.

In the illustrated embodiment, a seal material 36 made of an elastic material such as rubber is additionally provided over the entire length of the lower surface of the support piece 30 to prevent rainwater from entering.

The cover member 8 attached to the support member 7 is also a narrow plate-like member, and the left and right side edges have locking pieces folded back to the back side.
At the front end, a covering piece 37 having a substantially U-shaped cross section for covering the locking portion 3 of the roof material 1 is formed at the front end. If a cutout 38 is provided at the center of the folded-back lower end portion 37a of the covering piece 37, rainwater that has entered can be discharged. That is, in the conventional coupling device, since the bottom bent portion of the scrapboard is only locked to the engaging portion of the roof material, when a storm is applied to the roof from the front, if the cutout exists in the cover material, Although the notch sometimes became a weak point in terms of rain finish, in the configuration of the receiving member 6 and the roof material 1 of the present invention, since the double end is inserted up to the rear end, the above weak point is solved and the connecting portion is formed. It is possible to promote the drainage of water that has entered. In addition, the rear end of the cover member 8 is bent into a desired shape to provide an insertion piece 39. Incidentally, the front end side and the rear end side of the locking piece 34 are cut off to provide an insertion portion 40 and a stop portion 41 in which the locking piece 34 does not extend. When the cover member 8 is attached to the support member 7, the front edge 34 ′ of the locking piece 34 is locked to the cut edge 33 ′ of the stopper 33 of the support member 7.

Next, the construction method will be explained. In order to construct a roof by using the waste plate 5, the receiving member 6, the supporting member 7, and the cover member 8 having the above-described configurations, a base plate such as a ground plate (not shown) is used. No)
While placing the scrapboard 5 on the upper side, the lower bent portion 10 is made to face the engaging portion 2 of the roofing material 1 located on the lower side of the slope (Figs. 14 and 15).
Figure). Then, the receiving material 6 is placed almost at the center of the scrapboard 5 to position the receiving material 6. That is, the tip end 20 of the adhered portion 18 of the receiving member 6 is brought into contact with the rear end 21 of the engaging portion 2 of the roofing material 1 located on the lower side of the slope to perform positioning (first
Figure). By doing so, even if the position of the wasteboard 5 is somewhat loose, the position of the roofing material 1 to be laid next can be accurately ensured. Then, the side edge lower surfaces of the left and right roofing materials 1 are placed on the surface of the receiving material 6 from the left and right so that the lower bent portions 10 of the scrapboard 5 are covered with the locking portions 3 of the left and right roofing materials 1 laid on the inclined upper side. It is (Fig. 15).

Next, the supporting material 7 is positioned on the surface of the receiving material 6 on which the side edges of the left and right roofing materials 1 are placed, and the overlapping pieces 31 of the supporting material 7 are placed on the locking portions 3 of both roofing materials 1. , The locking protrusion 17 constituting the engaging / disengaging means is passed through the circular portion 26a of the deformation hole 26, and the elongated hole portion 26b is formed.
By moving the locking collar portion 17a to the long hole portion 26b.
It is locked to the side end of (Fig. 9, Fig. 16). At this time,
Since the deformation hole 26 is formed in the projecting portion 27, the projecting portion 27 is pressed against the flat portion 12 of the receiving member 6 so that the supporting piece 30 of the supporting member 7 and the side edge of the roofing member 1 are made of the roofing member 1. Closely touches the entire length in the depth direction. In the illustrated embodiment, since the block 23 is provided at the rear edge of the receiving member 6, the engaging portion 2 of the roof material 1 fits into the fitting groove 22 of this block 23. Further, the sealing material 36 attached to the lower surface of the support material 7 is pressed against the upper surface of the roof material 1 to surely prevent rainwater from entering (FIG. 17).

As described above, according to the present embodiment, not only the horizontally long roofing material 1 can be laid without moving left and right, but also the support material 7 can be attached and fixed very easily, so that even an inexperienced worker can do so. It can be installed easily and the working time can be greatly reduced.

Next, the cover member 8 is applied to the support member 7 fixed as described above. The left and right cutouts 35 provided in the support member 7 are fitted with the insertion portion 40 at the rear end of the cover member 8. The locking piece 34 is placed along the lower surface of the support piece 30, and the cover material 8 is raised along the support material 7. As a result, the cover member 8 has left and right locking pieces.
34 is supported by sandwiching the support piece 30 of the support member 7. Then, when the cover material 8 is sufficiently pushed in, the adhered piece 37 becomes the roof material 1.
Stopper portion provided on the support member 7 while covering the locking portion 3 of
The cut edge 33 ′ of the cover material 8 is locked to the 33. Therefore, the roof material 1 does not roll up due to strong winds, and the cover material 8
Does not fall off (Fig. 16).

Although the present invention has been described with reference to the embodiments of the drawings, the present invention is not limited to the above-described embodiments, and any structure may be changed within the scope of the configuration described in the claims. It can also be implemented. For example, the engaging portion 2 and the locking portion 3 provided on the roof material, or the adhered portion 18 provided on the receiving material 6
Are not limited to the illustrated embodiment,
If they can be engaged with or brought into contact with each other, they can be formed into an appropriate shape.

<Effects of the Invention> In short, the present invention is configured by sequentially laying a roofing material having an engaging portion bent on the front side at the upper edge and an engaging portion bent on the back side at the lower edge. In a horizontal thatched roof, a slab that is placed on the lower surface of the portion that connects the roofing material in the lateral direction, a receiving material that is placed on the upper surface of the siding board and that receives the side edges of the left and right roofing materials, and the receiving material It consists of a support material that is located on the upper surface and supports the side edge upper surfaces of the left and right roof materials, and a cover material that adheres to the support material. Since the tip of the adhered portion is brought into contact with the rear end of the engaging portion of the roof plate located on the lower side in the laid state, this is the case when the engaging portion of the roof material is crushed. However, since the position of the back end does not change, the positioning of the receiving material with this back end as a reference point is stable, so the support material, The position of the cover material with respect to the roof material is also stable, and it is possible to enhance the function of rain as a connecting device as a whole. Moreover, since the receiving material for directly receiving the roof material is positioned, the disposition of the wasteboard is relatively loose, and the construction becomes easy and the construction time can be shortened. And the present invention is
Since many years of experience and skill are not required for construction, it is possible to provide a coupling device that can be easily constructed even with artificial construction.
