Description

  The present invention relates to a folded plate roof structure and a construction method thereof.

  In recent years, metal roofs with durability and beautiful appearance have become widespread. Patent Document 1 describes a roof structure in which rising portions of non-plated long steel plates such as stainless steel are welded and fixed together by seam welding. This roof structure is excellent in water tightness and durability because it uses a stainless steel plate, but is expensive because it uses stainless steel. For this reason, it is often used for permanent public facilities such as museums, exhibition halls, and airports. The problem with such a roof structure is that it is expensive to spread widely.

  Further, Patent Document 2 describes a folded plate roof structure composed of a folded plate that is a plated steel plate, and can solve the above-described problem of high cost. In general, a plated steel plate is not suitable for welding. In the same roof structure, the ends of adjacent folded plates are fixed to a tight fastener (hanger 9 in the same document) fixed to a tight frame (in the same document, a chevron 14). Folded and tightened, so-called clamping. Thus, the roof structure comprised of folded plates is excellent in terms of light weight and cost. Therefore, such a roof structure is frequently used in a building having a required useful life of 20 years or less, such as a factory or a warehouse.

  In describing a roof structure using a long steel plate such as a folded roof, hereinafter, a long direction of the long steel plate is referred to as a longitudinal direction, and a direction orthogonal to the long direction is referred to as a width direction. In the metal waterproof structure roof described in Patent Document 1, as shown in FIG. 11 (C), the upright portion J34 of the long stainless steel plate J16a and the adjacent upright portion J23 of the adjacent long stainless steel plate J16b are fixed to the base JT. The hanging piece movable piece J49 is sandwiched. Furthermore, the folding part J24 extended in the adjacent standing part J23 has wound the movable part J49 and the standing part J34. In addition, the folded portion J24, the upright portion J34, the hanging piece movable piece J49, and the adjacent upright portion J23 are seam welded over the entire longitudinal direction. This weld is a seam weld J57b.

  The construction method of the metal waterproof structure roof is shown in FIGS. 11 (A) and 11 (B1). As shown in FIG. 11A, first, the movable hanging piece J49 is sandwiched between the upright portion J34 and the adjacent upright portion J23. After that, before the folded portion J24 is bent, the standing portion J34, the movable movable piece J49 and the adjacent standing portion J23 are locally welded, for example, spot welding J57a. This is a temporary fixing to prevent the upright portion J34 and the adjacent upright portion J23 from shifting when the folded portion J24 is bent. Moreover, it is also a temporary stop for preventing a shift | offset | difference at the time of performing seam welding J57b over the whole longitudinal direction, such as the standing part J34 and adjacent standing part J23, in a post process.

  As shown in FIG. 11C, the metal waterproof structure roof finally maintains negative pressure proof stress by seam welding J57b over the entire longitudinal direction. Here, the negative pressure is a pressure for sucking the roofing material upward, and is generated by a typhoon, a gust or a tornado. Negative pressure strength is the ability to maintain the roof structure without being destroyed by this negative pressure.

  It will be described below that the negative pressure proof stress cannot be maintained only by spot welding J57a and the folded portion J24 as shown in FIG. When the negative pressure acts, the long stainless steel plate J16a tries to rotate around the inner area of the broken-line circle PA (FIG. 11 (B2)). The metal waterproof structure roof is constructed by fixing the vicinity of the butt end of the upright portion J34 having no bent portion and the movable movable piece J49 having no bent portion by a local spot welded portion J57a. The weld J57a and the folded portion J24. The folded portion J24 is a steel plate that is softer than the movable hanging piece J49, and is not sufficient to prevent the long stainless steel plate J16a from rotating. In addition, since the spot welded portion J57a is formed inside the broken circle PA, which is the rotation center of the long stainless steel plate J16a, it is inappropriate for the purpose of generating a moment for suppressing the rotation. Therefore, it is impossible to maintain the negative pressure proof strength only with the spot weld J57a and the folded portion J24.

  The metal waterproof structure roof described in Patent Document 1 has maintained negative pressure proof stress by performing seam welding over the entire length of the stainless steel plate. On the other hand, since the folded plate used for the folded plate roof structure is a plated steel plate, it is generally difficult to weld. Among plated steel sheets, steel sheets plated with an alloy having an aluminum weight ratio of 55% are said to have relatively good weldability. However, welding still has difficulty, such as fouling the terminals of electric welding. In the case of welding, it is necessary to take measures such as limiting the welding location rather than welding the entire connecting surface.

  The folded-plate roof structure represented by the roof structure described in Patent Document 2 is excellent in water tightness and strength, but also in terms of a lightweight structure, although it has a simple structure of tightening. However, there is a problem that when a negative pressure exceeding the allowable level is applied due to a bomb low pressure or a gust of wind, the folded plate connecting portion by tightening is disassembled and the roof structure is destroyed. Therefore, an object of the present invention, that is, a technical problem to be solved is to provide a folded plate roof structure with improved negative pressure proof stress and a construction method thereof while using a folded plate that is not suitable for welding fixation. .

  With reference to FIG. 9, the structure of the conventional typical clamped folded board is confirmed. FIG. 9A shows a long plated steel plate to be processed into a folded plate which is a long roof plate. For convenience of explanation, one of the folded plates formed from the plated steel plate is referred to as a folded plate 3, and the folded plate installed adjacent thereto is referred to as an adjacent folded plate 4. In principle, the folded plate 3 and the adjacent folded plate 4 are folded plates having the same shape. For convenience of explanation, the long direction is referred to as a longitudinal direction, and a direction orthogonal to the longitudinal direction is referred to as a width direction.

  The central part of the folded plate 3 and the adjacent folded plate 4 is a strip-shaped main plate 32, which is a portion that forms the folded plate roof body. A long first folded plate connecting portion 31 is provided at one end of the folded plate 3 and the adjacent folded plate 4. The first folded plate connecting portion 31 is provided with a first folded plate connecting tip 311 that is long from the outside toward the main plate 32, a first folded plate connecting central portion 312, and a first folded plate connecting neck 313.

The second folded plate connecting portion 41 includes a long second folded plate connecting portion, a second folded plate connecting tip 411 that is long from the outside toward the main plate 32, and a second folded plate connecting center. A portion 412 and a second folded plate connecting neck portion 413 are provided (FIG. 9A).

  In forming the folded plate roof structure, the folded plate 3 and the adjacent folded plate 4 are arranged so as to be adjacent to each other, and the first folded plate connecting portion 31 of the folded plate 3 is the second folded plate connecting portion 41 of the adjacent folded plate 4. Are formed in a state where they overlap with each other or close to each other. Moreover, the folding plate 3 and the adjacent folding plate 4 are wound in the longitudinal direction of these folding plates by the hook-like coupling tool 23 fixed to the tightening receiving casing 1 by the coupling portion fixing tool 21 every predetermined distance. Is fixed to the clamp receiving housing 1. The hook-like connector 23 and the connecting portion fixing tool 21 are collectively referred to as the tightening stopper 2.

  FIG. 9B is a view in which the plated steel plate is processed into a folded plate to form a roof structure, and is a view seen in the direction of Y1-Y1. The folded plate 3 and the adjacent folded plate 4 are fixed to the tightening receiving case 1 by the tightening stopper 2 composed of the hook-shaped connecting device 23 and the connecting portion fixing device 21. The tightening receiving case 1 is fixed to a beam (not shown) provided in the building body. As described above, in the folded plate roof structure, the folded plate 3 and the adjacent folded plate 4 are so-called clamped and connected by the first folded plate connecting portion 31 and the second folded plate connecting portion 41. Further, the folded plate 3 and the adjacent folded plate 4 are fixed to the building main body by winding a hook-like connector 23 fixed to the tightening receiving case 1 every predetermined distance.

  FIG. 9C shows an example of a fastening device 2 composed of a general hook-shaped connector 23 and a connecting portion fixture 21. The hook-like connector 23 has a connector neck 233 that rises vertically upward, and a wrap-around connector central portion 232 and a connector tip 231 that extend forward. The upper part of the connector neck 233 is also referred to as a rising central part of the hook-like connector 23, and the lower part thereof is also referred to as a rising lower part of the hook-like connector 23. In addition, the hook-like connector central portion 232 is referred to as a rising upper portion of the hook-like connector 23. FIG. 9D shows an example in which the folded plate 3 and the adjacent folded plate 4 are fixed to the tightening receiving case 1 by the tightening fastener 2.

  And it arrange | positions so that the 1st folding plate connection part 31 of the folding plate 3 and the 2nd folding plate connection part 41 of the adjacent folding plate 4 can be connected. In addition, the second folded plate coupling tip portion in a state where the coupling tool center portion 232 and the coupling tool tip portion 231 fold and hold the first folded plate coupling tip portion 311 and the first folded plate coupling center portion 312. 411 and the second folded plate coupling central portion 412 are tightened so as to entrain the coupling central portion 232 and the coupling distal end portion 231. By this tightening, the first folded plate connecting neck portion 313 that is long and the second folded plate connecting neck portion 413 that is long are configured to sandwich the connector neck portion 233. With the above configuration, two or more folded plates are connected and fixed to the tightening receiving case 1.

  10A and 10B are cross-sectional views of the folded plate roof structure at a place other than the tightening support frame. As described above, most of the folded plate roof structure has a cross section in which the tightening receiving case 1 and the tightening fastener 2 are not present. That is, the two folded plates are connected by the second folded plate connecting portion 41 winding the first folded plate connecting portion 31 of the adjacent folded plates. The above is a general folded plate roof structure.

  This folded plate roof structure has excellent strength despite being lightweight. However, if a negative pressure exceeding the allowable value acts on the folded plate roof structure from above, the winding structure of the first folded plate connecting portion 31 by the second folded plate connecting portion 41 is broken, and the folded plate roof structure is disassembled. It will be. According to our research, the collapse of the entrainment structure may be caused by the fact that the first folded plate connecting neck 313 and the second folded plate connecting neck 413 are separated by the action of negative pressure exceeding the tolerance. I know. FIG. 10C shows an exploded view of the folded plate roof structure in a region where the tightening receiving case 1 and the tightening fastener 2 do not exist, and FIGS. 10D, 10E and 10F show the tightening receiving case 1 and the tightening. The decomposition | disassembly of the folded-plate roof structure in the area | region where the fastener 2 exists is shown.

[Principle of negative pressure resistance improvement and configuration of the first embodiment]
Based on FIG. 1, the principle that the folded-plate roof structure of the present invention has excellent negative pressure resistance will be described, and a first embodiment of the folded-plate roof structure of the present invention will be described together. FIG. 1 is a diagram showing the connection between folded plates in the first embodiment of the folded plate roof structure of the present invention. The state where the folded plate 3 and the adjacent folded plate 4 which are long roof boards formed with the plated steel plate are connected is shown. This is a cross-sectional structure including a tightening receiving case 1 fixed to a beam (not shown) and a tightening stop 2 fixed to the tightening receiving case 1. The tightening stopper 2 is composed of a hook-like connector 23 and a connecting portion fixture 21.

  The connecting portion fixture 21 is fixed to the tightening receiving case 1. In FIG. 1A, the first folded plate connecting portion 31 of the folded plate 3 and the second folded plate connecting portion 41 of the adjacent folded plate 4 are the rising center portion or the lower rising portion of the hook-shaped connecting device 23, and the connecting device neck portion 233. Is pinched. And the said 1st folded plate connection part 31, the said coupling tool neck part 233, and the said 2nd folded plate connection part 41 are being fixed by 5 A of welding parts. The weld 5A is local welding, for example, spot welding.

  In a general folded plate roof structure, since there is no welded portion 5A, when negative pressure exceeding the tolerance is applied to the folded plate roof, both sides are lifted up like the folded plate 3 and the folded plate 4 shown by broken lines, This leads to the destruction of the folded roof structure as described above. However, in the folded plate roof structure of the present invention, the local welded portion 5A is formed at a place deviated from the inside of the broken-line circle PA, which is the center of fracture. For this reason, the 1st folded-plate connection part 31 and the 2nd folded-plate connection part 41 do not leave | separate easily from the coupling tool neck part 233, and a folded-plate roof structure is maintained. The above is the principle for improving the negative pressure resistance. As described above, the folded plate roof structure has an effect of improving the negative pressure proof stress despite the extremely limited local welding.

  Further, FIG. 1B shows that the hook-like connector 23 is in a state where the second folded plate connecting portion 41 is wound, and the connector central portion 232 which is the upper part of the hook-like connector 23 and the first folded plate connected. A local welded portion 5 </ b> B is provided between the portion 31 and the second folded plate connecting portion 41. The local welding is, for example, spot welding. In this example, the welded part 5B is provided in the broken-line circle PA. Here, the first folded plate connecting portion 31 is bent along the hook-shaped connector 23, and the second folded plate connecting portion 41 is wound around the hook-shaped connector 23 so that the welded portion 5B is formed. Yes.

  Thus, since the welded part 5B is formed with the hook-like connector 23 as a core and the bending of the first folded plate connecting part 31 and the entrainment of the second folded plate connecting part 41, the broken line PA is formed. Even with the spot welding provided, the negative pressure resistance can be effectively improved. Furthermore, since the welded portion is above the hook-shaped connector 23, it is easy for the contractor to visually recognize and there is an effect that it is easy to work because there is no need to squat down.

  FIG. 1C shows an example in which folded plates are connected by a cross connector 23D. The cross connector 23D has a connector central portion 232D extending horizontally on the upper portion of the connector neck 233D that is vertically rising, and has a connector tip portion 231D at the tip. In order to distinguish both sides of the connector neck portion 233D, the connector neck portions 233Da and 233Db may be referred to. The cross-connecting tool 23D can be fixed to the tightening receiving case 1 by the connecting portion fixing tool 21D. The cross connecting tool 23D and the connecting portion fixing tool 21D may be collectively referred to as a fastening tool 2D.

  In the folded plate roof structure according to the present invention, the first folded plate connecting portion 31 is welded to any location from the connecting device central portion 232, which is a horizontal extending portion of the cross connecting device 23D, to the connecting device distal end portion 231. It is the structure fixed by the part 5C. Further, the second folded plate connecting portion 41 is fixed by a welded portion 5C at any location from the connecting device central portion 232 to the connecting device tip portion 231 which is a horizontally extending portion of the cross connecting device 23D. . The welded part 5C is also local welding, for example, spot welding.

  In the folded plate roof structure, since the welded portion 5C is formed at a location outside the broken circle PA, the first folded plate connecting portion 31 and the second folded plate connecting portion 41 are easily separated from the connector neck portion 233. The folded roof structure is maintained. As described above, the folded plate roof structure has an effect of improving the negative pressure proof stress despite the extremely limited local welding. In addition, since welding is performed on the upper portion of the cross-connecting tool 23D, there is an effect that the operator is not squatting down and the work load is light.

[Configuration of Second Embodiment]
Next, based on FIG. 2, the structure of 2nd Embodiment of the folded-plate roof structure of this invention is demonstrated. In the second embodiment of the folded plate roof structure of the present invention, the first folded plate connecting neck portion 313 and the second folded plate connecting neck portion 413 are arranged in a folded plate roof structure cross section in which the tightening receiving case 1 and the fastening fastener 2 are present. Each of them is a structure in which local welding is performed on a portion of the tightening fastener 2 that can contact the connector neck 233. In the example shown in FIGS. 2A and 2B, the first folded plate connecting neck 313, the connecting tool neck 233, and the second folded plate connecting neck 413 of the folded plate 3 are fixed by local welding, for example, spot welding. And is represented as a weld 5A1.

  The disassembly of the folded plate roof structure is triggered by the opening between the first folded plate connecting neck portion 313 of the folded plate 3 and the second folded plate connecting neck portion 413 of the adjacent folded plate 4, so this portion is welded. Adhering as part 5A1 can prevent the folding plates from opening efficiently. Therefore, there is an effect of maximizing the negative pressure proof strength of the folded plate roof structure while minimizing the number of welds. Moreover, since a through-hole is not provided in a board | plate material and it tightens with a volt | bolt etc., there exists an effect that watertightness is ensured. Further, the folded plate roof structure has an effect that the negative pressure proof stress can be enhanced by adding the welded portion 5A1 to the existing roof.

[Configuration of Third Embodiment]
Next, based on FIG. 3, the structure of 3rd Embodiment of the folded-plate roof structure of this invention is demonstrated. The folded plate roof structure is locally applied to a portion where the first folded plate connecting neck portion 313 can contact the connecting device neck portion 233 of the tightening stop device 2 in the cross section of the folded plate roof structure where the tightening receiving case 1 and the fastening device 2 exist. It is the structure which makes a proper welding. In the example shown in FIGS. 3A and 3C, the first folded plate connecting neck 313 and the connecting tool neck 233 of the folded plate 3 are fixed by local welding, for example, spot welding, and expressed as a welded portion 5A2. Has been. The second folded plate connecting portion 41 is not welded but is wound so as to cover the welded portion 5A2.

  Therefore, in the perspective view of FIG. 3 (A), the tightening stopper 2 and the welded portion 5A2 are covered with the second folded plate connecting portion 41 and are invisible, and thus are indicated by broken lines. In order to construct this configuration, as shown in FIG. 3 (B), it is necessary to form the weld 5A2 before the fastening device 2 is rolled up by the second folded plate connecting portion 41. Also in the folded plate roof structure, the negative pressure proof stress is improved by the welded portion 5A2. Further, in the construction of the folded plate roof structure, since the fastening fastener 2 is welded before being covered with the second folded plate connecting portion 41, there is an effect that the position of the fastening fastener 2 can be easily confirmed.

[Configuration of Fourth Embodiment]
Next, based on FIG. 4, the structure of 4th Embodiment of the folded-plate roof structure of this invention is demonstrated. In the folded plate roof structure, the first folded plate connection center portion 312 and the second folded plate connection center portion 412 are respectively provided in the folded plate roof structure cross section in which the tightening receiving case 1 and the tightening fastener 2 exist. It is the structure which welds locally to the part which can contact | connect the connector center part 232 of this. In the example shown in FIGS. 4A and 4B, the first folded plate coupling central portion 312, the coupler central portion 232, and the second folded plate coupling central portion 412 of the folded plate 3 are locally welded, for example, spot welding. And is represented as a weld 5B1. Also in the folded plate roof structure, the negative pressure proof stress is improved by the welded portion 5B1. Further, in the construction of the folded plate roof structure, since welding is performed on the upper portion of the fastening fastener 2, the installer standing on the folded plate roof structure can be visually recognized without squatting down, so that the construction is easy.

[Configuration of Fifth Embodiment]
Next, based on FIG. 5, the structure of 5th Embodiment of the folded-plate roof structure of this invention is demonstrated.
In the folded plate roof structure, the first folded plate connection central portion 312 and the connection tool central portion 232 of the tightening fastener 2 can be in contact with each other in the cross section of the folded plate roof structure where the tightening receiving frame 1 and the fastening fastener 2 are present. It is the structure which performs local welding. In the example shown in FIGS. 5A and 5C, the first folded plate connecting central portion 312 and the connecting tool central portion 232 of the folded plate 3 are fixed by local welding, for example, spot welding, and the welded portion 5B2. It is expressed as In order to form the welded part 5B2, as shown in FIG. 5B, the first folded plate coupling central portion 312 and the first folded plate coupled before the coupling tool tip 231 is wound by the second folded plate coupling unit 41. The central part 312 is welded. Since the tightening stopper 2 is covered with the second folded plate connecting portion after the weld 5B2 is formed, the weld 5B2 cannot be visually recognized in the perspective view in FIG. Therefore, in the figure, the contact 5B2 is indicated by a broken line.

  The folded plate roof structure also has improved negative pressure resistance. In addition to this effect, the position where the welded portion 5B2 is formed is the upper portion of the tightened portion, and there is an effect that it is easy to construct because the installer standing on the folded plate roof structure can visually recognize without squatting. Furthermore, since the fastening portion 2 is welded before it is covered with the second folded plate connecting portion 41, there is an effect that the position of the fastening portion 2 can be easily visually confirmed. In addition, the welded portion of the first folded plate connecting central portion 312 is wound inside by tightening and is not exposed to direct wind and rain.

[Configuration of Sixth Embodiment]
Based on FIG. 6, 6th Embodiment of the folded-plate roof structure of this invention is described. FIGS. 6A and 6C are cross-sectional views of the folded plate roof structure at the position of the tightening receiving case 1C, and FIGS. 6B and 6E are cross-sectional views where the tightening receiving case 1C does not exist. . In addition, FIG. 9A is also referred to as appropriate for portions common to the conventional folded plate structure. The folded plate roof structure is a folded plate roof structure in which folded plates, which are long roof plates made of plated steel plates, are connected by a cross connector 23C. Further, some of the cross-connecting tools 23C have a connecting portion fixing tool 21C, and are fixed to the tightening receiving case 1C.

  The cross connecting tool 23C having the connecting part fixing tool 21C is also referred to as a tightening stopper 2C including the connecting part fixing tool 21C. A folded plate which is a long roof plate constituting the folded plate roof structure has a strip-shaped main plate 32C (indicated as 32 in FIG. 9A) in the center, and is long at one end on both sides thereof. The first folded plate connecting portion 31C (denoted as 31 in FIG. 9A) is provided, and the other end has a long second folded plate connecting portion 41C (denoted as 41 in FIG. 9A). Is provided. The first folded plate connecting portion 31C of the folded plate 3C and the second folded plate connecting portion 41C of the adjacent folded plate 4C are arranged so as to be close to each other.

  The first folded plate connecting portion 31C of the folded plate 3C and the second folded plate connecting portion 41C of the adjacent folded plate 4C are both folded and held in the cross connector 23C, thereby connecting the folded plate 3C and the adjacent folded plate 4C. (FIG. 6C). Further, the first folded plate coupling portion 31C and the second folded plate coupling portion 41C connected to each other sandwich the coupling tool neck 233C in the cross coupling tool 23C, so that the folded plate 3C and the adjacent folded plate 4C are fastened together. It is fixed via the tool 2C. So far, it is common with the conventional folded-plate roof structure. However, the folded plate roof structure includes the first folded plate coupling neck portion 313C of the first folded plate coupling portion 31C, the coupling neck portion 233C of the fastening fastener 2C, and the second folded plate coupling neck portion 413C of the second folded plate coupling portion 41C. Are locally fixed by welding (FIG. 6D).

  For example, a local weld 5A1 realized by spot welding is formed here. In addition, the long cap member 6 is configured to cover the first folded plate connecting portion 31C, the second folded plate connecting portion 41C, and the cross connector 23C. The cap material 6 may be the same length as the folded plate 3C and the adjacent folded plate 4C, but is configured as a cap material shorter than these, and a plurality of cap materials are used to form the folded plate 3C and the adjacent folded plate 4C. The first folded plate connecting part and the cross connector 23C may be covered.

  The tightening stopper 2C includes a connecting portion fixing tool 21C fixed to the tightening receiving housing 1C and a cross-connecting tool 23C (FIG. 6D). The cross connector 23C includes a connector neck 233C extending vertically, a first extending central portion 232Ca, a second extending central portion 232Cb, and a first extending tip portion 231Ca and a second extending portion which are orthogonally fixed thereto. It is comprised by installation tip part 231Cb. The first extending tip portion 231Ca and the second extending tip portion 231Cb are key-shaped so that the first folded plate connecting portion 31C of the folded plate 3C and the second folded plate connecting portion 41C of the adjacent folded plate 4C can be folded and held. It has become.

  Further, as shown in FIG. 6G, the folded plate 3C and the adjacent folded plate 4C can be coupled by the cross connector 23C alone, and even in this case, the first folded plate coupling portion 31C of the first folded plate coupling portion 31C can be connected. A structure in which the neck portion 313C, the connecting portion neck portion 233C of the cross connecting portion 23C, and the second folded plate connecting neck portion 413C of the second folded plate connecting portion 41C are locally welded and fixed by the welded portion 5A1 is provided. Can be strengthened.

  The first folded plate connecting portion 31C of the folded plate 3C has a long first folded plate connecting tip 311C, a long first folded plate connecting central portion 312C, and a long length in order from the end toward the main plate 32C. A first folded plate connecting neck portion 313C which is a scale is provided. The second folded plate connecting portion 41C, which is the other end of the folded plate 3C, has a long second second folded plate connecting tip portion 411C and a long first one in order from the end toward the main plate 32C. A second folded plate coupling center portion 412C and a long second folded plate coupling neck portion 413C are provided. The adjacent folded plate 4C has the same structure as the folded plate 3C. The above is the folded plate roof structure in the portion where the tightening receiving case 1C exists.

  In the folded plate roof structure, the tightening receiving case 1C is provided at a predetermined interval in the longitudinal direction of the folded plate. Therefore, many regions of the folded plate roof structure have a structure in which the tightening receiving case 1C and the tightening fastener 2C do not exist. This is the structure shown in FIGS. 6B and 6E. A folded plate 3C having a folded first folded plate coupling tip 311C and a first folded plate coupling center 312C, a folded second second folded plate coupling tip 411C, and a second folded plate coupling center. The adjacent folded plate 4C having 412C is in contact with the first folded plate connecting neck portion 313C and the second folded plate connecting neck portion 413C, and these are covered with a long cap member 6. Further, as shown in FIG. 6G, the negative pressure proof stress can be strengthened by the cross connector 23C and the welded portion 5A1 even in the absence of the tightening receiving case 1C.

  The decomposition of the folded plate roof structure due to the negative pressure triggered the opening of the first folded plate connecting neck 313C of the folded plate 3C and the second folded plate connecting neck 413C of the adjacent folded plate 4C adjacent thereto. Therefore, fixing this part with welding 5A1 can prevent the folding plates from opening efficiently. Therefore, there is an effect of maximizing the negative pressure proof strength of the folded plate roof structure while minimizing the number of welds. Moreover, since a through-hole is not provided in a board | plate material and it tightens with a volt | bolt etc., there exists an effect that watertightness is ensured. Furthermore, since these welded portions are covered with the long cap material 6, there is an effect that the portion where the plating is peeled off during the welding process is not directly exposed to wind and rain.

[Configuration of Seventh Embodiment]
Next, a seventh embodiment of the folded plate roof structure of the present invention will be described. In the folded plate roof structure, the cap member 6, the tightening receiving case 1C, the tightening fastener 2C, the folded plate 3C, and the adjacent folded plate 4C in the folded plate roof structure of the sixth embodiment are the same member.

The neck 233C is sandwiched. And these are covered with the cap material 6 which is long.

  Furthermore, the first folded plate connecting central portion 312C and the first extending central portion 232Ca are welded and fixed by a local welded portion 5C. Further, the second folded plate connecting central portion 412C and the second extending central portion 232Cb are welded and fixed by a local welded portion 5C. That is, the first folded plate connecting portion 31C and the second folded plate connecting portion 41C are locally fixed by welding at the local welded portion 5C via the tightening fastener 2C.

  In the folded plate roof structure according to the seventh embodiment, the folded plate 3C and the adjacent folded plate 4C are firmly connected to each other at a place where the fastening fastener 2C is located via the fastening fastener 2C and the welded portion 5C. Even if there are few places, there exists an effect which can provide the folded-plate roof structure excellent in negative pressure proof stress. Moreover, since a through-hole is not provided in a board | plate material and it tightens with a volt | bolt etc., there exists an effect that watertightness is ensured. Furthermore, since these welded portions are covered with the long cap material 6, there is an effect that the portion where the plating is peeled off during the welding process is not directly exposed to wind and rain. Further, at the time of construction before the long cap material 6 is mounted, the welded portion is facing upward, so that there is an effect that the operator can easily see and work easily. Further, as shown in FIG. 7C, the folded plate 3C and the adjacent folded plate 4C can be connected by the cross connector 23C even in a place where the tightening receiving case 1C does not exist. Even in this case, it is possible to strengthen the negative pressure proof stress by providing the welded portion 5C.
