With the first side face locked to the upper surface of the chevron portion A of the support frame, a temporary fixing tool 26 is fitted and mounted from the upper surface and both ends thereof are hooked. Therefore, it suffices that the recesses that can be fitted to the protrusions on the first and second side surfaces of the metal folded plate are formed. As in this embodiment, it is assumed that the recesses are simply formed toward the inside of the frame member. Alternatively, as will be described later, the support frame is configured as a U-shaped frame as a fixed frame, and a horizontal receiving plate is separately attached to the upper surface in the horizontal direction and fitted into the recess formed by the horizontal receiving plate. You may do it. Also, the support frame may have any other shape or structure.

As shown in FIG. 5, the metal folding plate 20 is made of a thin metal plate such as an aluminum plated plate or a copper plate, and the first side surface 24a is formed on one end of the flat portion 22 having a width of about 1 m. A second side surface 24b is bent at the other end of 22. The first side surface 24a has a first protrusion 32a at its intermediate height position, which is engaged with the concave portion 28 of one of the first and second frame members 14 and 16 of the movable support frame 18, and a first protrusion 32a. The first circular arc portion 34a is connected to the first projecting portion 32a and is mounted on the cutout chevron portion 12 of the movable mold supporting frame 18 while leaving a part thereof. A recess 36 is provided which fits in the central gap of the cutout chevron 12 of the frame 18.

The second side surface 24b is, similarly to the first side surface 24a, a second protrusion 32b at an intermediate height position thereof, and a cutout of the movable support frame 18 that is connected to the second protrusion 32b. A second arcuate portion 34b mounted on the chevron portion 12 is provided, and a return piece 38 engaged with the recess 28 of the frame member of the movable support frame 18 is provided at an end of the second arcuate portion 34b. A concave portion 36 corresponding to the central gap of the cutout chevron portion 12 is provided.

As a result, the first side surface 24 a and the second side surface 24 of the adjacent metal folding plates 20, 20 can be superposedly mounted on the upper surface of the movable support frame 18, and the first and second side surfaces 24 a, 24 b can be stacked. The first and second protrusions 32a and 32b are attached to the recesses 28 and 28 of the frame members 14 and 16, and the return piece 38 of the second side surface 24b is attached to the recess 28 to form the first and second protrusions. The side surfaces 24a and 24b are prevented from being removed from the movable support frame 18.

A feature of the present invention is that the first side surface formed at one end of the flat portion of the metal folding plate is fitted to the chevron portion of the support frame so as to follow the chevron portion of the front view support frame. A fixture for a metal folding plate that is plate-shaped and is mounted and temporarily fixed from the upper surface of the metal folding plate while the first side surface of the metal folding plate is locked to the chevron portion of the support frame.

As shown in FIG. 3, in this embodiment, the temporary fixing member 26 is made of a thin metal plate slightly thicker than the metal folding plate 20, and is formed along the cutout chevron portion 12 of the movable supporting frame 18. It is composed of a curved plate 40 that is bent into. Then, hook portions K fitted into the recesses 28 are provided on both ends of the curved plate 40.

These hooks K are engaged with the recesses 28, 28 of the first and second frame members 14, 16 of the movable supporting frame 18, and are gradually curved downward in a mushroom shape. The curved surface 40a is connected and bent inward.

A concave portion 36 corresponding to the central gap of the mountain-shaped portion 12 of the movable support frame 18 is provided in the central portion of the curved surface 40a continuously with the curved surface 40a. Further, in order to prevent the displacement of the bending plate 40 in the frame width direction when the bending plate 40 is attached to the notched chevron portion 12 of the movable supporting frame 18, the bending plate 40 is bent at least downward to an end surface position near one end of the bending plate 40. A pair of claw pieces 44, 44 are provided. With this temporary fixing tool 26, the first arcuate portion 34a of the first side face 24a mounted on the cutout chevron portion 12 of the movable die support frame 18 is pressed and fitted into the notch chevron portion 12a. The hooks K at both ends of the fixture 26 are engaged with the recesses 28, 28 of the first and second frame members 14, 16, and the central recess 36 together with the recess 36 of the first arc portion 34a has a mountain-shaped notch. By pressing the first side surface 24a to the central gap of the portion 12, the first side surface 24a is firmly locked to the movable support frame 18 and is prevented from rising or being displaced. Further, on the steeply inclined roof surface, by locking the first side surface 24a to the movable supporting frame 18 with the temporary fixing tool 26, the metal folding plate 20 can be prevented from sliding down.

In the embodiment, the movable type support frame 18 having the first and second frame members is used as the support frame, but the present invention is not limited to the movable type frame, and is simply a U-frame type or a gate type. A horizontal support plate is attached and fixed in the horizontal direction on the upper surface of the frame, and a fixed type support frame is provided with recesses on the side surfaces of the metal folding plate, which are the fitting portions of the first and second side surfaces. It may be. The shape and structure of the frame does not matter.

The point is that the first side face formed at one end of the flat portion of the metal folding plate is fitted into the chevron portion of the support frame, and has a plate shape that follows the chevron portion of the support frame in a front view. Any fixing tool of the metal folded plate to the support frame may be used, in which the first side surface of the metal folded plate is locked to the chevron portion of the support frame, and is tightly attached from the upper surface of the support frame to temporarily mount and fix the support frame.

Rather, in the case of the fixed type support frame, a thin metal plate slightly thicker than the metal folding plate is used, so that when the temporary fixing tool 26 is pushed down from the upper surface side to be mounted and fixed, this temporary fixing tool is used. In the case of No. 26, the hooks K at both ends are elastically expanded and curved like springs, and when the installation is completed, the hooks K return to their original positions, so that the first side surface of the metal folding plate is supported. It is firmly fixed to the frame. In that state, if the second side surface side of the metal folding plate is installed while being pushed down from the top surface, the first side surface side does not come up and the smooth fitting is possible. It is used to fix the supporting frame to the holding frame, such as fastening bolts and nuts of metal folding plates. In other words, this allows it to withstand a large wind pressure from the lower surface side, and also has the function of a fixing tool rather than temporary fixing. The second side surface 24b is further fitted and fitted from the upper surface side where the first side surface 24a is fitted and fitted, and the first and second side surfaces of the metal folding plate 20 are fitted into the recess 28 of the support frame. Even with this alone, the metal folding plate can be firmly fixed to the support frame, and the one that retains great strength against the wind pressure from the lower surface side is the temporary fixing member 26 from the upper surface of the first side surface. The metal folded plate on the 2nd side is attached and fitted from the upper surface of the metal folded plate to secure the strength. At the same time, the other end side of the metal folded plate floats up when working. And effectively prevent such problems and significantly improve the work efficiency of rooting the seed shop.

Next, the operation of the temporary fixture of the metal folded plate for the support frame according to the embodiment will be described. As shown in FIG. 6, a plurality of roof base materials 46 laid on the roof surface in parallel with the eaves tip. The movable die supporting frame 18 is installed on the upper surface of the metal folding plate 20 by welding or the like with the same gap as the mountain portion of the metal folding plate 20. At the position of the movable supporting frame 18, the first side surface 24a of the metal folding plate 20 and the second side surface 24b of the metal folding plate 20 to be connected next are combined with each other in a chevron shape.

As shown in FIG. 4, for example, a metal folding plate 20 is installed on the roof base material 46 from the left side of each movable type support frame 18 arranged in the longitudinal direction along the inclined surface. While mounting the first side surface 24a on each movable mold support frame 18, the first projecting portion 32a of the first side surface 24a is engaged with the concave portion 28 of each first frame 14, and the first arc portion 34a is formed into a notched chevron portion. The concave portion 36 of the first arc portion 34a is brought into contact with the upper surface of the first circular arc portion 12 and fitted in the central gap of the notch-shaped portion 12 to prevent the first and second frame members 14 and 16 from closing and contracting.

In this state, the first projecting portion 32a and the first arc portion 34a of the first side surface 24a are forcibly pulled in due to the displacement of the movable support frame 18, etc., and temporarily fixed at the engaged position. The tool 26 is pressed from the upper surface of the first side surface 24a to the notch mountain portion 12 of the movable mold support frame 18 so that the hook portions 42, 42 at both ends are formed in the recesses 28, 28 of the first and second frame members 14, 16, respectively. The first side surfaces 24a are engaged with each other and temporarily fixed to the upper surface of each movable die support frame 18 by fitting the temporary fixing tool 26 to the movable die support frame 18 at appropriate intervals. It is possible to prevent the displacement of the movable support frame 18 and the rise of the movable support frame 18.

Further, in the temporary fixing tool 26, the claw pieces 44, 44 at the ends thereof can be engaged with the end surface of the second frame member 16 to prevent the frame members from coming off due to the displacement in the width direction. . However, it goes without saying that the first side face 24a can be sufficiently locked to the movable support frame 18 without necessarily providing the claw piece 44.

Next, the second circular arc portion 34b of the second side surface 24b of the metal folding plate 20 that is towed on the right side of the movable support frame 18 is polymerized so as to cover the temporary fixture 26 and the first side surface 24a. Meanwhile, the return piece 38 at the end is engaged with the recess 28 of the first frame member 16, and the second protrusion 32b of the second side surface 24b is engaged with the recess 28 of the second frame member 16, thereby providing a temporary fixing tool. Mutual connection of the metal folding plates 20 by the metal folding plate mounting structure 10 Finish the joint, and successively join the metal folding plates 20 with the metal folding plate mounting structure 10 with the temporary fixing tool to roof the roof surface. It is a thing.

As described above, the first side surface of the metal folding plate is attached to the support frame fixed to the upper surface of the roof base material 46, and in this state, the temporary fixing tool 26 is pushed down from the upper surface to elastically spring like a spring. The temporary fixing tool and the first side surface 24a pressed by the temporary fixing tool are tightly fixed to the support frame 18 by mounting and closely fitting to the support frame. As a result, the metal folding plate on the first side face side is substantially firmly fixed to the support frame. Therefore, if the metal folded plate on the second side surface is fitted and fitted so as to be pushed down from the upper surface thereof, it will have two, three, four ,. ． ． Due to the mountain-shaped type, the first side surface side is fixed and the second side surface is further fitted from the upper surface to provide a roof structure with an extremely strong metal folded plate roof.

Therefore, the first side surface 24a does not float up or shift in position during construction, and it is not necessary to make adjustments for mounting the second side surface 24b of the next metal folding plate 20, and the first side surface 24a can be mounted immediately. As a result, it is possible to improve the efficiency of roofing work on the roof surface using metal folding plates, and to maintain a high strength against the wind pressure from the lower surface side.
