Description

The present invention relates to a reinforcing tool suitable for reinforcing eaves and keraba of a folded plate roof widely used in a large area roof such as a factory, a warehouse, and a large store.

The folded-plate roof is originally made of a steel plate coil, which is then roofed using a roofing material molded into a desired shape and length by a roll molding machine installed at a manufacturing factory and a construction site. Therefore, it is widely used as a roof that can economically secure workability, wind pressure resistance, and water stoppage.

Specifically, the folded plate roofing material includes a bottom plate forming the bottom wall of the groove portion, a side plate rising from the bottom plate, and a mountain plate connected to the upper end portion of the side plate to form the top wall of the mountain portion. The roofing materials are connected to each other by engaging means such as upper goby and lower goby provided on the mountain plate.

By the way, in this kind of folded-plate roof, a negative pressure load that swells upward acts on the outdoor air pressure when the outdoor air pressure drops during a storm. A normal goby folded plate is fixedly supported at the center of an adjacent mountain, and the side plate and bottom plate have a large bulge deformation to the outer surface, and at the tip, it is supported in a protruding state, so it is tightened with a goby. There is a greater risk that the joint will be deformed and opened and scattered.

As prior art in this regard, for example, in Patent Document 1, a surrounding portion that covers an engaging portion of a folded plate roof from above, a ground contact portion formed at both lower ends of the surrounding portion, and the surrounding portion or its vicinity thereof. A reinforcing metal fitting for a folded plate roof, which is formed or provided on the roof and has a locking means for locking to an engaging portion, has been proposed.

Japanese Unexamined Patent Publication No. 2000-345662

However, the reinforcing metal fittings disclosed in Patent Document 1 are premised on those that lock the goby portion on the left and right, and the goby shape is limited to a round shape, so that the applicable range is narrow. In addition, although the reinforcing metal fittings have a structure in which they are supported by surface contact with the goby part of the folded plate roof, for example, when snow is accumulated, the reinforcing metal fittings are pushed by the snow and easily misaligned. In addition, there is a risk of damaging the coating film applied to the outer surface of the roofing material when misalignment occurs. Further, since the metal fitting is composed of a plurality of members, there is a limit in reducing the cost of the metal fitting itself, and it is hard to say that a simple mounting work can be carried out.

An object of the present invention is to propose a simplified reinforcing tool having a structure that can easily and surely reinforce a folded plate roof, particularly its eaves and keraba, regardless of the difference in the engagement type of the folded plate roof material. It is in.

The present invention includes a folded plate including a bottom plate forming the bottom wall of the groove, a side plate connected to the bottom plate and rising from the bottom plate, and a mountain plate connected to the upper end of the side plate to form the top wall of the mountain portion.

It is a figure which showed the right side surface of 13.

As the reinforcing tool for the folded plate roof according to the present invention, for example, one made of a thin steel plate having a thickness of about 2.5 mm is used, but the thickness and the material thereof can be appropriately changed. In addition, the reinforcing tool is basically attached to each mountain part of the eaves of the folded plate roof or the keraba at the roof end to reinforce the folded plate roof. The folded-plate roof shall include both the existing folded-plate roof and the newly built folded-plate roof.

Reference numerals 3 in FIGS. 3 to 14 are on the back surface side of the mountain plates 1d and 1e, and the top plates 4a and 4b arranged along the width direction of the mountain plates 1d and 1e are pieces at both ends of the top plate 3. The hanging plate, 5a, which is held hanging in a holding state and is arranged along the back surface side of the side plates 1b and 1c in the upper portion of the side plates 1b and 1c (in this example, a region of about 1/3 of the total length). Reference numeral 5b is a tongue piece integrally connected to the hanging plates 4a and 4b.

The tongue pieces 5a and 5b are configured to wrap around from the edge of the side plates 1b and 1c and are located on the surface side of the side plates 1b and 1c, and preferably elastically displaceable and the side plates 1b. It is preferable to use 1c as a clip piece to be sandwiched between the hanging plates 4a and 4b, and at the end thereof, the side plates 1b and 1c are easily sandwiched and the side plates are prevented from being scratched. Bent portions 5a1 and 5b1 bent in a direction away from the outer surface of 1b and 1c are provided. The length L of the hanging plates 4a and 4b (see FIG. 4) can be the same as the length of the side plates 1b and 1c, but the length L of the hanging plates 4a and 4b is the same as the side plates 1b and 1c. In this case, the size of the reinforcing tool becomes large and the weight also increases, so that it is preferably about 1/3 of the length of the side plates 1b and 1c.

Further, reference numeral 6 is a rib extending from one hanging plate 4a through the top plate 3 toward the other hanging plate 4b. By providing the rib 6, the rigidity of the reinforcing tool itself can be increased. The rib 6 is formed by molding the reinforcing tool into a predetermined shape and then press-molding the rib 6. The number can be increased or decreased as needed, and is not limited to the one shown in the figure. When the rib 6 is formed by press molding, a groove having the same size as the rib 6 is formed on the opposite surface on which the rib 6 is formed.

Further, reference numerals 7a and 7b are through-opening holes provided in the tongue pieces 5a and 5b , and 8a and 8b are through-opening holes provided in the hanging plates 4a and 4b . Of the through-opening holes 7a and 7b, the through-opening hole 7a communicates with the through-opening hole 8a, and the through-opening hole 7b communicates with the through-opening hole 8b. The reinforcing tool is firmly fixed to the folded plate roof material by screwing the drill screws penetrating the side plates 1b and 1c into the through openings 7a and 8a and the through openings 7b and 8b, respectively. When the through holes 7a, 7b, 8a, 8b are provided, the side plates 1b and 1c are shown in FIG. 15 using a jig inside the through holes 7a, 7b, 8a, 8b. It may be extruded (caulked), and the reinforcing tool can also be fixed to the folded plate roofing material.

Normally, in this type of folded plate roof, when a negative pressure acts on the folded plate roof material in a strong wind or the like, as shown in FIG. 16, the folded plate roof material engages with the folded plate roof material. It may be rotated starting from (upper haze 1f, lower haze 1g), and especially in the eaves of the folded plate roof (the folded plate roof material overhangs about 500 mm) and the keraba, the roof material rises and deforms. As mentioned above, there is a concern that the engagement portion of the folded plate roofing material may be disengaged, but the reinforcing tool according to the present invention is a side plate on the back side surface of the mountain portion Y of the folded plate roofing material. Since 1b and 1c are suppressed, the influence of negative pressure can be reliably prevented.

The reinforcing tool according to the present invention is made of a single member manufactured by bending a plate-shaped body cut into a shape as shown in FIG. 17, and has only a simplified structure. However, it has the advantage of being easy to install.

The rib 6 is formed by press-molding after finishing the bending process of the plate-shaped body, but for example, rod-shaped members may be joined by welding or the like, and this point is not particularly limited.

The reinforcing tool according to the present invention is not only a folded plate roofing material having a square roof as shown in FIGS. 1 and 2 and 11 to 14 above, but also a folding plate roof having a round roof as shown in FIG. To a plate roofing material, a folded plate roofing material having a fitting cap 8 as shown in FIG. 19, or a folded plate roofing material which forms a superposed portion 9 as shown in FIG. 20 and connects the roofing materials to each other. Can be applied, and the eaves and keraba can be reliably reinforced with any folded plate roofing material.
