Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fixed-length folded plate having alternating peaks and valleys with a predetermined length.

[0002]

[Prior art]

 The folded plate is formed by molding a thin steel plate so as to have peaks and valleys alternately. Normally, the length of one folded plate in the flow direction is the length from the ridge to the eaves, and the working width is the length having several peaks and valleys. In this way, a folded plate has a large area that can be constructed with one piece, and because it can be molded relatively easily, it is often used for roofs of buildings with a large construction area, such as large buildings such as factories, warehouses, and leisure facilities. ing.

When constructing a folded plate, the folded plate is engaged with a tight frame fixed to the beam at regular intervals, and the folded plates adjacent to each other on the left and right are connected by bolts or the like. Folded plates can thus be constructed relatively easily.

Folded plates are used for large-scale buildings for the reasons described above, but in recent years, structures such as stadiums and exhibition halls have become even larger, and the roof per building has increased accordingly. The construction area of the building has also increased, and the length in the flow direction from the building to the eaves has become longer, some of which exceed several hundred meters.

As described above, as the length in the flow direction from the ridge to the eaves increases, the length of the folding plate used naturally also increases. Folded plates are usually molded in factories and transported by a trailer or the like to the construction site. However, the maximum length that can be transported by the trailer is around 20 meters. The molding machine was brought in and the folding plate was molded and constructed at the construction site. In this case, due to the workability of folded plates, a forming machine was installed in the part corresponding to the eaves of the roof of the building, and thin steel coils were placed in the forming machine to form folded plates.

When the molding machine is carried into the construction site and the folded plate is molded in this way, a support stand dedicated to the molding machine is installed because the molding machine is installed in the part corresponding to the eaves of the roof of the building as described above. A coil of thin steel plate having a length substantially the same as the length in the flow direction had to be mounted on the support base. Therefore, it is necessary for the support to have a structure that can withstand the weight of the molding machine and the coil of thin steel sheet, and the structure has sufficient strength and durability to create that support, which is both costly and labor-intensive. As a result, the cost was high.

Further, the molding machine is installed in a portion corresponding to the eaves of the roof of the building. As mentioned above, when the molding machine is brought into the construction site, the building is large and the roof eaves are Parts are also high places. For this reason, there is a problem in that the work of forming the folded plate is a work at a high place and is dangerous.

For this reason, a fixed-length folded plate formed by molding a thin steel plate having a predetermined length has been used. The fixed-length folded plate does not need to be molded at the construction site, and thus has the advantage that it can solve the above-mentioned problems and is easier to handle than conventional folded plates. When constructing fixed length folded plates, adjacent fixed length folded plates were connected to each other on the left and right sides, and fixed length folded plates located above and below the flow direction were also connected.

[0009]

[Problems to be solved by the device]

 However, when connecting the fixed length folding plates located above and below in the flow direction, as shown in FIG. 8, simply stack the fixed length folding plates as shown in FIG. As shown in FIG. 8B, a waterproof material is sandwiched between the fixed-length folded plate and the fixed-length folded plate, and the fixing member is fixed. The fasteners used to connect the standard length folding plates are often tex (same as the product name below), but the thickness of the standard length folding plate is thin as shown in the figure, so the screw thread of the tex However, there is a problem in that it is not possible to use it properly because the joining becomes shallow and a sufficient fixing force cannot be obtained.

Further, as described above, many of the buildings using the fixed-length folded plate are large-sized, and the fixed-length folded plate is greatly affected by vibrations such as typhoons and strong winds and vibrations such as earthquakes. End up. This shaking or vibration moves the fixed-length folding plate shown in Fig. 8 in the left-right direction in the drawing. However, when the connected fixed-length folding plates move in opposite directions, the tex sticks to the fixed-length folding plate. As shown in FIG. 9, the holes opened during the operation became large due to the texture, and there was a risk that rainwater or the like would enter through the larger holes.

Although a fixed length folding plate is constructed in consideration of the shaking and vibration, it suffers from such shaking and vibration over a long period of time, which causes damage to the fixed length folding plate and causes a long period of time. There was a problem that it could not be used.

The present invention has been made in view of the above problems, and provides a fixed-length folded plate that can obtain a sufficient fixing force when connecting the fixed-length folded plate and can be used for a long period of time. It is intended to be offered.

[0013]

[Means for solving problems]

 Therefore, the present invention is a fixed-length folded plate formed by alternately forming peaks and valleys of a thin steel plate of a predetermined length, and the fixed-length folded plate is provided on the back surface of the ridge-side end of the fixed-length folded plate. The backing material, which is formed to have almost the same cross-sectional shape, is fixed.

[0014]

[Action]

 The backing material fixed to the back surface of the ridge side of the fixed-length folded plate has the function of thickening the fixed-length folded plate at the connecting part when connecting thin fixed-length folded plates. As a result, the fixing by the fixing device becomes reliable, so that a sufficient fixing force can be obtained.

Further, even if there is shaking due to a strong wind such as a typhoon, or vibration such as an earthquake, the backing material has a function of thickening the fixed-length folded plate of the connecting portion and a function of reinforcing the portion for a long time. It can be used over a wide range.

As shown in FIG. 1, a standard length folding plate according to the present invention is provided with a backing material 2 having substantially the same cross-sectional shape as the standard length folding plate 1 on the back side of the ridge side end of the standard length folding plate 1. It is fixed.

The fixed-length folded plate 1 is made of a thin steel plate and, as shown in FIG. 1, is molded so as to have a ridge portion 1a, a valley portion 1b, and an inclined portion 1c.

The backing material 2 is made of a thick steel plate and is molded so as to have a ridge portion 2a, a valley portion 2b, and an inclined portion 2c as shown in FIG. 2, and the ridge portion 2a and the valley portion 2b. , And the inclined portion 2c have substantially the same cross-sectional shape as the ridge portion 1a, the valley portion 1b, and the inclined portion 1c of the standard length folded plate 1, and as shown in FIG. It can be fixed to the back surface of the folding plate 1 without any gap.

Next, the connection of the fixed length folding plate 1 will be described. First, as shown in FIG. 3, the fixed length plate 1 having the backing material 2 fixed to the back surface of the ridge side end is fixed to the tight frame 5 fixed on the beam 6 as shown in FIG. 4A. Then, the eaves-side end of the fixed-length folded plate 1 to be newly connected is installed from above, and the overlapped portions are fixed by the fixing device 3 to be connected as shown in FIG. 4B. At this time, rainwater or the like may enter from the overlapped portions due to the capillary phenomenon, so the waterproof sheet 4 is attached to the overlapped portions before connecting.

When the fixed-length folded plates 1 connected in this way are connected to each other as shown in FIG. 5, the thickness of the fixed-length folded plates 1 as well as the thickness of the backing material 2 are In addition, since the screw thread of the tex can be deeply screwed when being fixed by the fixing device 3, for example, the tex, a sufficient fixing force can be obtained, and rattling may occur in the fixed length folding plate 1 after the connection. Disappear.

Further, even if the fixed-length folded plates 1 are connected to each other by shaking due to a strong wind such as a typhoon or vibration such as an earthquake, and the fixed-length folded plates 1 move in directions opposite to each other, the screw thread of the fixture 3 may be changed. Since it is deeply screwed into the backing material 2, it has a function to minimize the movement, that is, a function to reinforce the connection part, so it was opened when the fixing tool 3 was fixed to the fixed length folding plate 1. The holes are less likely to become large and can be used for a long period of time.

When connecting the fixed length folding plates 1 to each other, the overlapped portions are fixed by the fixing tool 3, but since the backing material 2 has almost the same cross-sectional shape as the fixed length folding plates 1, As shown in FIG. 6, the fixing device 3 can be fixed not only on the peaks 1a of the fixed-length folded plate 1 but also on the valleys 1b and the inclined portions 1c.

As described above, according to the present invention, the backing material 2 is fixed to the back surface of the ridge-side end of the fixed-length folded plate 1, so that the thickness of the fixed-length folded plate 1 when the fixing member 3 is fixed.
