Description

[Technical Field]

[0001] The present invention relates to a method for constructing a folded plate roof that can extremely easily and quickly construct a folded plate roof that prevents plate squealing in a folded plate roof made of a fastening type folded plate roof plate, and to the folded plate roof. [Background technology]

[0002] Conventionally, many roofs, walls, and other exterior structures have been constructed using metal folded roof panels. The folded roof panels that make up such exterior structures have connecting bent sections (e.g., fastening sections) formed on both sides in the width direction. A number of such folded roof panels are arranged side by side, and the connecting bent sections of adjacent folded roof panels are connected via various connecting means to construct the exterior structure.

[0003] In enclosures constructed by connecting these types of folded-plate roof panels, a "squeak" phenomenon can occur. This "squeak" is a metallic sound that sounds like the roof, walls, or other enclosures being violently struck due to temperature differences in the outside air. This is caused by thermal expansion and contraction of the folded-plate roof panels in the longitudinal direction due to temperature differences based on the amount of sunlight they receive. When the thermal expansion and contraction amounts of adjacent folded-plate roof panels differ, the difference in the amount of thermal expansion and contraction between the panels causes the connecting bends to rub against each other, resulting in noise.

[0004] In particular, if the connecting bends are of the fastening type, the contact area between the fastening parts of adjacent folded-plate roof panels will be wider, and the difference in thermal expansion and contraction will cause a louder noise as the metal parts rub against each other at the connecting bends. The noise that occurs in this situation is called the board rattle, and it can be unpleasant for residents (including neighboring residents). The board rattle is also sometimes called the "sound rattle" in the construction industry.

[0005] The clunking phenomenon tends to occur especially when the connection between the folded roof panels is of the lash-fastening type. This is because the connection between the folded roof panels in the lash-fastening structure is connected by wrapping them around each other, and the contact area between the two folded roof panels is large compared to the cross section of the connection.

[0006] In order to prevent this type of plate squealing in a folded-plate roof with a fastened joint, various means have been developed. Among these, a particularly popular one is that disclosed in Patent Document 1 (JP 2002-339521 A), in which an insulator such as a foamed synthetic resin material is sandwiched between the connecting bent parts of the fastened joint to prevent the two connecting parts from coming into direct contact with each other, thereby preventing the generation of noise caused by the two connecting parts rubbing against each other. This type is the most common. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-339521 Summary of the Invention [Problem to be solved by the invention]

[0008] However, in the above structure, an insulator is placed between the two connecting parts at the joint of the fastening type. Specifically, the insulator is entirely adhered to either the front surface of the inner connecting part or the back surface of the outer connecting part. The process of adhering the insulator entirely to the front surface of the inner connecting part or the back surface of the outer connecting part must be carried out extremely carefully and accurately. Furthermore, the shapes of the inner connecting part and the outer connecting part are quite complex, with several bends. Therefore, attaching the insulator to the inner connecting part or the outer connecting part is difficult, tedious, and takes a long time.

[0009] As described above, attaching insulation to the joints of folded-plate roof panels to prevent the clattering phenomenon is an extremely difficult task, which hinders construction efficiency and time reduction. Therefore, the object of the present invention is to realize a method for constructing a folded-plate roof that can prevent or reduce the clattering phenomenon, while still achieving the same level of finish as conventional methods, in an extremely simple and efficient manner.

As described above, the widthwise end of the buffer seal is adhered only to the outer end of the upper run portion, and the non-adhesive area protruding toward the inside of the widthwise direction of the upper run portion other than the adhesive area where the outer end of the buffer seal is adhered to the upper run portion of the upper run portion of the buffer seal is designated as an inward protrusion, and the upper run portion of the corrugated plate roof panel is placed over the lower run portion of the adjacent front corrugated plate roof panel, and the outward protrusion of the buffer seal is pressed down together with the upper run portion so that the buffer seal is interposed between the upper run portion and the lower run portion of the front corrugated plate roof panel, and the lower run portion and the upper run portion are fastened together with a fastening machine, and this process is repeated sequentially. This method of construction for a corrugated plate roof has been characterized by the above-mentioned.

[Effects of the Invention]

[0016] The invention of claim 1 comprises a corrugated roof panel having a lower rung portion formed at one upper end of the width direction of the main panel and an upper rung portion formed at the other end, and a buffer seal, the width direction length of which follows the outer shape of a cross section perpendicular to the longitudinal direction of the upper rung portion and is equal to or greater than the length from the lower end of the neck portion of the upper rung portion to the tip of the top surface portion.

[0017] The buffer seal is bonded only to the neck of the upper running portion near one end in the width direction, and the non-bonded region protruding outward in the width direction of the lower running portion of the buffer seal is called the outward protruding portion. In other words, the buffer seal is bonded only to the upper running portion, and the other portion of the buffer seal in the width direction (X direction), i.e., the outward protruding portion, is non-bonded to the upper running portion and can deform freely.

[0018] With the above configuration, the buffer seal is securely fixed by the adhesive point between the cushion seal and the neck of the upper rung, and in the process of overlapping the lower rung of the corrugated roof panel with the lower rung of another adjacent corrugated roof panel, the outward protrusion of the buffer seal bends freely along the back side of the upper rung, and can deform to follow the shape of the back side of the upper rung.

[0019] By properly fastening the lower and upper rungs together, the buffer seal will be in close contact with both the outer surface of the lower rung and the back surface of the upper rung, resulting in a folded-plate roof that can prevent the clunking phenomenon.The buffer seal can also be sufficiently positioned between the lower and upper rungs.

[0020] In this way, the entire width of the buffer seal is not adhered to the upper rung portion, but only one side, which is the widthwise end portion that is part of the buffer seal, is adhered to the upper rung portion.As a result, the outer protrusion is a free portion, and the outer protrusion does not inadvertently adhere to the back surface of the upper rung portion, and can be fastened very well while being sandwiched between the lower rung portion and the upper rung portion.

[0021] As described above, by pressing down the outward protruding portion of the buffer seal attached to the upper rung portion of the next folded-plate roof panel so that it covers the lower rung portion of the previous folded-plate roof panel that has already been installed in the specified position, when the lower rung portion and the upper rung portion overlap, the buffer seal is interposed between the lower rung portion and the upper rung portion. After that, by fastening the lower rung portion and the upper rung portion with a fastening machine, a folded-plate roof with a buffer seal interposed between the lower rung portion and the upper rung portion of the adjacent folded-plate roof panels can be easily and quickly constructed.

[0022] In the past, to prevent the clunking phenomenon, the entire surface of the buffer seal was carefully and precisely bonded to the upper rung of the folded-plate roof panel, thereby preventing or reducing the clunking phenomenon. However, bonding the entire surface of the buffer seal to the lower rung requires an extremely careful finish, which makes the work extremely troublesome and time-consuming, and inexperienced workers often fail to bond the buffer seal to the lower rung.

[0023] In addition, when the lower and upper rungs of adjacent folded-plate roof panels are fastened together, the recess formed in part of the semicircular mountain-shaped part of the lower rung forms a gap in the rung connection. If rainwater attempts to seep in between the lower and upper rungs, the capillary phenomenon that prevents rainwater from seeping in between the lower and upper rungs of the rung connection is blocked by the gap formed by the recess, and the rainwater can be prevented from seeping in at the recess.

[0024] The invention of claim 2 achieves effects substantially equivalent to those of the above-mentioned claim 1. The width direction end of the buffer seal is bonded only to the outer end of the upper run portion, and the portion of the buffer seal other than the bonded portion to the outer end of the upper run portion that is a non-bonded area protruding inward in the width direction of the upper run portion is configured as an inward protruding portion, and substantially similar to claim 1, the work of bonding the buffer seal to the lower run portion is significantly simplified, and a folded-plate roof of the same quality as a folded-plate roof can be constructed, which can prevent or reduce the plate squeal caused by the conventional process, is not affected by the skill of the worker, improves work efficiency, shortens work time, and reduces the labor burden on the worker.

[0025] In the invention of claim 3, the recessed portion of the lower rung portion is formed in the widthwise center of the mountain-shaped semicircular portion, allowing the mountain-shaped semicircular portion to elastically expand and contract in the widthwise direction (X direction), resulting in an extremely strong structure when the lower rung portion and the upper rung portion are fastened together. Furthermore, the infiltration of rainwater can be effectively prevented at the fastened joint between the lower rung portion and the upper rung portion. In claims 4 and 5, similarly to claim 3, the recessed portion allows elastic expansion and contraction, resulting in an extremely strong structure when the lower rung portion and the upper rung portion are fastened together. Furthermore, the infiltration of rainwater can be effectively prevented at the fastened joint between the lower rung portion and the upper rung portion.

[0026] In the invention of claim 6, the buffer seal is made of a foamed resin sheet, which further reduces noise caused by thermal expansion and contraction. In the inventions of claims 7 and 8, a buffer seal can be installed between the lower and upper rungs of adjacent folded-plate roof panels with extremely simple construction, resulting in a folded-plate roof that can prevent or reduce plate squealing.

DETAILED DESCRIPTION OF THE INVENTION

[0028] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The present invention relates to a construction method for a folded-plate roof equipped with a structure for preventing board rattles, and to the folded-plate roof. The present invention has a first and a second embodiment, and the folded-plate roof panel 1 and construction method in the first embodiment will be described first, followed by the second embodiment. In the first embodiment of the present invention, the folded-plate roof A is composed of a plurality of folded-plate roof panels 1, 1, .... In addition to the folded-plate roof panels 1, 1, ..., brackets 4, retaining clips 5, and structural materials 3 such as purlins and furring strips are provided (see Figure 11).

[0029] Then, a plurality of such folded plate roof panels 1 are arranged in parallel along the width direction (X direction), and the lower run portions 12 and upper run portions 13 of adjacent folded plate roof panels 1, 1 are connected by fastening processing to construct a folded plate roof A. The folded plate roof A is constructed as a single layer roof as shown in Figure 11. Although not specifically shown, it may also be constructed as a two-layer roof in which a new folded plate roof A is constructed on top of an existing or new lower layer folded plate roof A.

[0030] For ease of explanation, the folded plate roof panel 1 is set to have a width direction and a length direction, with the width direction being the X direction and the length direction being the Y direction. The inner side of the width direction (X direction) of the folded plate roof panel 1 is the side of the main panel 11, and the outer side is the side where the main panel 11 is not present (see Figure 2(A)). The X direction and Y direction of the folded plate roof panel 1 also apply to the direction of a folded plate roof constructed using the folded plate roof panel 1. Therefore, the width direction of the folded plate roof A is the X direction, and the roof slope direction connecting above and below water is the Y direction.

[0031] The folded-plate roof panel 1 is of a fastening type, with a lower fastening portion 12 formed at one end of the width direction (X direction) of the main panel 11 and an upper fastening portion 13 formed at the other end (see Figure 2(A)). The main panel 11 has a bottom 11a and rising side portions 11b, 11b formed at both ends of the bottom 11a in the width direction, with rising peaks 11c formed at the upper ends of both rising side portions 11b, 11b pointing outward, with a lower fastening portion 12 formed on one side of both rising peaks 11c and an upper fastening portion 13 formed on the other side (see Figure 2(A)).

[0032] The bottom 11a is a flat plate-like portion, and the rising side portions 11b are formed as outwardly sloping wall surfaces from the bottom end to the top end. The rising top portion 11c is flat and approximately horizontal or has a gently sloping surface. The main plate 11 is formed into a roughly inverted trapezoid shape by the bottom 11a and both rising side portions 11b, and the shape becomes a deep or shallow valley depending on the height of both rising side portions 11b.

[0033] As shown in Figure 1, the lower running portion 12 and the upper running portion 13 have arc-shaped portions when viewed overall, forming a rounded shape (see Figure 1(A)). The lower running portion 12 has a neck portion 12a, a bent piece 12b, a mountain-shaped semicircular portion 12c, and a recessed portion 12d. The bent piece 12b is formed from the upper end of the neck portion 12a toward the inside in the width direction, and the mountain-shaped semicircular portion 12c is formed from the inner end of the bent piece 12b toward the outside. The neck portion 12a is a vertically rising portion (see Figures 1(A), 2(B), and (C)).

[0034] A bent piece 12b is formed from the upper end of the neck portion 12a toward the inward side in the width direction (X direction). The bent piece 12b is approximately horizontal or gently inclined, sloping slightly upward toward the inward side. The boundary between the neck portion 12a and the bent piece 12b is bent in an arc shape. A mountain-shaped semicircular portion 12c is formed from the inner end of the bent piece 12b in the width direction (X direction) toward the outward side in the width direction (X direction). The mountain-shaped semicircular portion 12c has a cross-sectional shape in the width direction (X direction) that is semicircular or inverted bowl-shaped (see Figures 1(A), (B), 2(B), and (C)).

[0035] A recess 12d is formed in a part of the mountain-shaped semicircular portion 12c. The recess 12d is formed by bending a part of the mountain-shaped semicircular portion 12c within the formation area of ​​the mountain-shaped semicircular portion 12c so that the part is recessed downward or toward the back side. The boundary between the bent piece 12b and the mountain-shaped semicircular portion 12c is continuous and deformed in an arc shape (see Figures 1 and 3(C)).

[0036] When the lower running portion 12 and the upper running portion 13 are fastened together, the recessed portion 12d forms a gap between the lower running portion 12 and the upper running portion 13, particularly between the mountain-shaped semicircular portion 12c of the lower running portion 12 and the half-mountain-shaped portion 13c or the wound portion 13d of the upper running portion 13. When rainwater attempts to seep in between the lower running portion 12 and the upper running portion 13 at the portion where the lower running portion 12 and the upper running portion 13 are fastened together, the gap formed by the recessed portion 12d blocks the capillary action of the rainwater and prevents the rainwater from seeping in due to capillary action.

[0037] The recess 12d may be formed at various locations on the mountain-shaped semicircular portion 12c, and may be formed at the center of the mountain-shaped semicircular portion 12c in the width direction (X direction) and at the top (see FIG. 1). The center of the mountain-shaped semicircular portion 12c in the width direction (X direction) may be approximately the center. The cross-sectional shape of the recess 12d is bent in a substantially V-shape, a substantially inverted triangle shape, or an inverted V-shape relative to the mountain-shaped semicircular portion 12c (see FIG. 1).

[0038] Furthermore, in the first embodiment of the present invention, the mountain-shaped semicircular portion 12c of the lower run portion 12 includes Modifications 1 and 2, which vary depending on the position of the recessed portion 12d. In Modification 1, which varies depending on the position of the recessed portion 12d relative to the mountain-shaped semicircular portion 12c, the recessed portion 12d is formed at the outer end of the mountain-shaped semicircular portion 12c in the width direction (X direction) (see FIGS. 8(A) and 8(B)). Furthermore, in Modification 2, which varies depending on the position of the recessed portion 12d relative to the mountain-shaped semicircular portion 12c, the recessed portion 12d is formed at the inner end of the mountain-shaped semicircular portion 12c in the width direction (X direction) (see FIGS. 8(C) and 8(D)). The recessed portion 12d in Modifications 1 and 2 is formed in a substantially L-shape or a substantially inverted L-shape.

[0039] The upper running portion 13 has a vertical neck 13a with a bent piece 13b extending inward in the width direction (X direction) from the top end thereof on the other side of the main plate 11 (the side opposite the side where the lower running portion 12 is formed), and a half-mounted portion 13c extending outward from the inner end of the bent piece 13b, with a wound portion 13d formed at the edge of the half-mounted portion 13c (see Figures 1(A), 2, 3(B), and 3(C)). Here, the outer side of the upper running portion 13 in the width direction (X direction) refers to the side of the half-mounted portion 13c of the upper running portion 13 where the main plate 11 is not present (see Figures 1 and 2(A)).

[0040] In other words, in FIG. 2(B), the left side of the half-mounted portion 13c of the upper running portion 13 is the outer side of the upper running portion 13 in the width direction (X direction). The inner side of the upper running portion 13 in the width direction (X direction) refers to the side where the main plate 11 is located, based on the half-mounted portion 13c of the upper running portion 13 (see FIGS. 1 and 2(A)). In other words, in FIG. 2(B), the right side of the half-mounted portion 13c of the upper running portion 13 is the inner side of the upper running portion 13 in the width direction (X direction). The neck portion 13a of the upper running portion 13 is a vertically rising portion, similar to the neck portion 12a of the lower running portion 12. The neck portion 13a of the upper running portion 13 is formed at the same height as, or slightly lower than, the neck portion 12a of the lower running portion 12. The bent piece 13b is a portion formed from the upper end of the neck portion 13a toward the inner side of the upper running portion 13 in the width direction.

[0041] Furthermore, the combined portion of the semi-angular portion 13c and the wound portion 13d of the upper running portion 13 is formed to have a larger outer shape than the semi-circular mountain portion 12c of the lower running portion 12, and the upper running portion 13 and the semi-angular portion 13c are configured so as to overlap with the semi-circular mountain portion 12c in a state of substantially embracing it (see FIG. 1). Furthermore, since the buffer seal 2, which will be described later, is sandwiched between the lower running portion 12 and the upper running portion 13, the upper running portion 13 and the lower running portion 12 are formed in consideration of the thickness of the buffer seal 2.

[0042] The semi-angular portion 13c of the upper running portion 13 overlaps the semi-angular portion 12c of the lower running portion 12 in the vertical direction so as to sandwich the buffer seal 2 (see Figures 4(1) to (3)). Furthermore, a wound portion 13d is formed from the tip of the semi-angular portion 13c of the upper running portion 13 (see Figures 1, 2(B), (C), 3(B), (C)).

[0043] An outer end piece 13e is formed near the outer end of the upper run portion 13, i.e., at the outer tip. This outer end piece 13e is the outer tip of the run portion 13d before it is fastened. In the present invention, the outer end piece 13e is part of the run portion 13d. As mentioned above, the run portion 13d is formed continuously from the tip of the half-mountain-shaped portion 13c. In the final step of the process of connecting the lower run portions 12 and upper run portions 13 of adjacent folded-plate roof panels 1, 1 by fastening, the entire run portion 13d is bent so that the outer end piece 13e is brought downward and close to the neck portion 12a of the lower run portion 12 (see Figures 1(C) and 4(3)). There is a second embodiment in which the widthwise (X-direction) end of the buffer seal 2 is adhesively joined to the outer tip portion of the upper winding portion 13, i.e., the back side of the outer end piece 13e of the winding portion 13d, and this second embodiment will be described later.

[0044] The buffer seal 2 is elastic or flexible and has a strip shape. Materials with such properties include natural and synthetic rubbers such as neoprene rubber, styrene butadiene rubber, urethane rubber, polybutadiene rubber, acrylic rubber, styrene rubber, fluororubber, silicone rubber, butyl rubber, and chloroprene rubber as elastic materials, and soft laminates such as long glass fiber laminates, soft synthetic resins such as soft PVC, and foam materials such as polyethylene foam and polyurethane foam as flexible materials.

[0045] The buffer seal 2 has a widthwise (X-direction) length equal to or greater than the cross section perpendicular to the longitudinal (Y-direction) direction of the upper running portion 13, i.e., the length along the widthwise (X-direction) contour of the upper running portion 13 from the lower end of the neck portion 13a on the back surface of the upper running portion 13 along the back surface to the outer end of the upper running portion 13 (see FIGS. 1(A), 2(B), and 2(C)). In the first embodiment of the present invention, the buffer seal 2 and the upper running portion 13 are bonded together by providing a sticky adhesive portion 2k in advance at the bonding site between the buffer seal 2 and the neck portion 13a of the upper running portion 13 (see FIGS. 1(A), 2(B), 2(C), and 3(A) and 3(B)). The adhesive portion 2k is linearly provided along the longitudinal (Y-direction) direction of the buffer seal 2. Alternatively, the adhesive portion 2k may be provided on the neck portion 13a side of the upper running portion 13.

[0046] The adhesive portion 2k may be a double-sided adhesive tape or an adhesive. When the adhesive portion 2k is a double-sided adhesive tape, a release paper is provided on the double-sided adhesive tape, and the release paper protects the adhesiveness of the adhesive portion 2k before installation. When the buffer seal 2 is to be adhered to the upper rung portion 13 of the folded-plate roof panel 1, the release paper is peeled off, and the buffer seal 2 is adhesively joined only to the neck portion 13a of the upper rung portion 13.

[0047] The proper adhesion of the buffer seal 2 to the neck portion 13a of the upper running portion 13 is achieved by arranging the longitudinal direction (Y direction) of the buffer seal 2 along the longitudinal direction (Y direction) of the upper running portion 13, and by adhesively joining one end of the buffer seal 2 in the width direction (X direction) only to the neck portion 13a of the upper running portion 13 (see Figures 1(A), 2(C), and 3(B)).

[0048] In the longitudinal direction (Y direction) of the buffer seal 2, the adhesive bonding range along the longitudinal direction (Y direction) of the neck 13a of the upper running portion 13 is either the entire longitudinal direction (Y direction) of the neck 13a (see FIG. 3(A)), or, although not shown, a partial adhesive bonding range in the longitudinal direction (Y direction) of the neck 13a, with this partial adhesive bonding range being arranged at a predetermined interval. In the case of an embodiment in which the adhesive bonding is partial in the longitudinal direction (Y direction) of the neck 13a, it is preferable that the buffer seal 2 is adhesively bonded to the position of the upper running portion 13 of the next folded plate roof 1 corresponding to the position of the portion where the lower running portion 12 of the previous folded plate roof 1 is fixed by the retaining clip 5.

[0049] As described above, one end portion of the buffer seal 2 in the width direction (X direction) is adhesively bonded only to the outer surface of the neck portion 13a of the upper running portion 13 (see Figs. 2(B) and (C)). The outer surface of the neck portion 13a refers to the portion facing outward in the width direction (X direction) of the upper running portion 13, and the upper end of the outer surface of the neck portion 13a is directly continuous with the back surface of the upper running portion 13. When the upper running portion 13 of the buffer seal 2 is bonded to the neck portion 13a, the portion of the buffer seal 2 in the width direction (X direction) other than the portion bonded to the neck portion 13a protrudes outward in the width direction (X direction) of the upper running portion 13 (see Figs. 1(A), (B), 2(C), and 3).

[0050] More specifically, when one end of the buffer seal 2 in the width direction (X direction) is adhesively joined only to the neck portion 13a of the upper running portion 13, the remaining portion of the buffer seal 2 in the width direction (X direction) that is not adhered to the neck portion 13a of the upper running portion 13 protrudes from the upper end of the neck portion 13a as described above (see FIGS. 1(A) and 2(C)). The portion of the buffer seal 2 that protrudes outward in the width direction (X direction) of the upper running portion 13 and is a non-adhesive region where no adhesive portion 2k exists is referred to as the outward protrusion 21. The outward protrusion 21 of the buffer seal 2 protrudes outward in the width direction (X direction) of the upper running portion 13 so that its cross section in the width direction (X direction) hangs down in a generally inverted U shape (see FIGS. 1(A), 2(C), and 3(C)).

[0051] As described above, the outward protrusion 21 is an area where the adhesive portion 2k does not exist, and is a portion where no adhesive, glue, double-sided adhesive tape, etc. is provided. The outward protrusion 21 is an area where the upper rung portion 13 and the lower rung portion 12 simply contact each other and are not adhered to each other, and is shown as a non-adhesive area in Figures 1(A), 2(B), and (C). In other words, since the outward protrusion 21 is a non-adhesive area, it can be freely deformed. The non-adhesive area of ​​the buffer seal 2 has the same concept as the outward protrusion 21. In other words, the outward protrusion 21 may also be called a non-adhesive area that protrudes outward.

[0052] When the lower running portion 12 and the upper running portion 13 are fastened together, the outward protrusion 21 of the buffer seal 2 is sandwiched so as to contact the outer surfaces of the neck 12a, bent piece 12b, and semicircular mountain-shaped portion 12c of the lower running portion 12 and the back surface of the neck 13a, bent piece 13b, and semicircular mountain-shaped portion 13c of the upper running portion 13. The lower end of the outward protrusion 21 sandwiched between the lower running portion 12 and the upper running portion 13 is configured to be aligned approximately with the lower ends of the neck 13a of the upper running portion 13 and the neck 12a of the lower running portion 12 (see Figures 1(C) and 5(7)).

[0053] The length Lo of the buffer seal 2 in the width direction (X direction) is equal to or greater than the length of the outer shape of the cross section perpendicular to the longitudinal direction of the upper running portion 13 (i.e., the outer shape along the width direction (X direction)) and along the back surface side (see Fig. 1(A), Fig. 2(B), (C)). In other words, the length Lo of the buffer seal 2 in the width direction (X direction) is equal to or greater than the length Lp of the outer shape of the cross section perpendicular to the longitudinal direction (X direction) of the upper running portion 13 and along the back surface side, and it is preferable to set it equal to or slightly longer.

[0054] More specifically, the length dimension Lo of the buffer seal 2 in the width direction (X direction) is equal to or greater than the length dimension Lp, which is the sum of the length dimension L1 of the neck portion 13a, the length dimension L2 of the bent piece 13b, the length dimension L3 of the half-mountain-shaped portion 13c, and the length dimension L4 of the wound portion 13d, in a cross section perpendicular to the longitudinal direction (Y direction) of the upper running portion 13. Note that "equal to or greater" here means that the difference between the length dimension Lo and the length dimension Lp is slight.

[0055] In this way, the length dimension Lo of the buffer seal 2 in the width direction (X direction) is set to be equal to or greater than the length dimension Lp of the cross section perpendicular to the longitudinal direction (Y direction) of the upper running portion 13, i.e., slightly larger than the length dimension Lp of the outer shape along the width direction (X direction) (see Figure 2(B)). In other words, Lo≧L1+L2+L3+L4 And Lp = L1 + L2 + L3 + L4. Therefore, Lo≧Lp. In addition, the length dimension in the width direction (X direction) of the outward protrusion 21 of the buffer seal 2 in the first embodiment is approximately equal to the sum of the length dimension L2 of the folded piece 13b of the upper running portion 13 and the length dimension L3 of the half-mountain-shaped portion 13c and the length dimension L4 of the wound portion 13d.

[0056] By setting the overall length of the buffer seal 2 in the width direction (X direction) as described above, when the lower run portion 12 and the upper run portion 13 are fastened together, the buffer seal 2 is substantially contained between the lower run portion 12 and the upper run portion 13 at the fastened portion between the lower run portion 12 and the upper run portion 13 (see Fig. 1(C) and Fig. 5(7)). Also, the lower run portion 12 may be slightly above or below the lower ends of the neck portions 12a and 13a of the lower run portion 12 and the upper run portion 13, but this is also within the conditions.

[0057] Next, we will explain the construction method of the folded plate roof A in the first embodiment of the present invention. Here, in the explanation of the invention, the terms previous position and next position are used in the process of constructing the folded plate roof A using the folded plate roof panels 1. The folded plate roof panel 1 in the previous position refers to one that has already been installed on the structural material 3 via the brackets 4 and retaining clips 5 during construction, and the folded plate roof panel 1 in the next position is one that is to be installed adjacent to the folded plate roof panel 1 in the previous position. Therefore, the folded plate roof panel 1 in the next position can become the folded plate roof panel 1 in the previous position by being installed.

[0058] First, the buffer seal 2 is adhered to the outer surface of the neck 13a of the upper rung portion 13 of the folded-plate roof panel 1 along the longitudinal direction (Y direction) of the upper rung portion 13 (see Figures 3(A) and (B)). The end (assuming it is one side portion) of the buffer seal 2 adhesively joined to the neck 13a of the upper rung portion 13 in the width direction (X direction) protrudes outward in the width direction (X direction) of the upper rung portion 13, and this portion is the outward protruding portion 21 that is the non-adhesive region of the upper rung portion 13 as described above (see Figures 1(A), 2(B), (C), and 3(B)).

[0059] In this way, the buffer seal 2 is adhesively bonded to the upper run portion 13 so as to satisfy the above-mentioned configuration at a predetermined location of the folded plate roof panel 1, and the folded plate roof panel 1 is positioned and fixed via structural members 3 such as beams, brackets 4, and retaining clips 5, etc., installed at the location where the folded plate roof A of the building is to be constructed. Next, the upper run portion 13 of the next-position folded plate roof panel 1, which will be placed in a position adjacent to the previously installed folded plate roof panel 1, is placed over the lower run portion 12 of the existing (previous position) folded plate roof panel 1 from above [see Figure 4(1)].

[0060] At this time, the upper run portion 13 of the next folded plate roof panel 1 is lowered vertically from directly above the lower run portion 12 of the previous folded plate roof panel 1 so that the upper run portion 13 of the next folded plate roof panel 1 covers the lower run portion 12 of the previous folded plate roof panel 1 (see Figure 4(1)). Alternatively, the upper run portion 13 of the next position may be rotated obliquely from above with the lower run portion 12 as the rotation center relative to the lower run portion 12 of the previous position so that the upper run portion 13 covers the lower run portion 12 (see Figure 6(B)).

[0061] In the process of covering the lower run portion 12 of the previous folded roof panel 1 with the upper run portion 13 of the next folded roof panel 1, the outward protrusion 21, which is the non-adhesive area of ​​the buffer seal 2 adhered to the neck portion 13a (or outer end piece 13e) of the upper run portion 13 of the next folded roof panel 1, abuts against the mountain-shaped semicircular portion 12c of the lower run portion 12 of the previous folded roof panel 1, and the upper run portion 13 of the next folded roof panel 1 is pushed down (see Figure 4 (2)).

[0062] The outward protrusion 21, which is the depressed non-adhesive area of ​​the cushioning seal 2, is interposed between the upper and lower running portions 13 and 12, and is sandwiched between the folded pieces 12b and 13b and the neck portions 12a and 13a, following the shapes of the folded pieces 12b and 13b and the neck portions 12a and 13a (see Figure 4(3)).

[0063] The upper run portion 13 of the next folded roof panel 1 has been completely placed over the lower run portion 12 of the previous folded roof panel 1, and a buffer seal 2 is properly interposed between the lower run portion 12 and the upper run portion 13, which are in the middle of being fastened before being fastened. In this state, the fastening machine 6 is placed at the longitudinal ends (Y direction) of the lower run portion 12 and the upper run portion 13, and the lower run portion 12 and the upper run portion 13 before being fastened are clamped between the receiving rolls 63 of the fastening machine 6 and the corresponding pressing rolls 62 (see Figures 4(4) and 5(5)).

[0064] Next, the clamping machine 6 is started, and the support roll 63 and the pressure roll 62 rotate. The clamping machine 6 moves the overlapping portion of the lower and upper run sections 12 and 13 along the longitudinal direction (Y direction) (see Figure 5(6)). This causes the lower run section 12 of the adjacent, previously installed folded-plate roof panel 1 to be clamped to the upper run section 13 of the next-position folded-plate roof panel 1 to be installed (see Figure 5(7)). The next-position folded-plate roof panel 1 then becomes the previous-position folded-plate roof panel 1, and a buffer seal 2 is bonded to the upper run section 13 of the next-position folded-plate roof panel 1 adjacent to it. This process is repeated sequentially to complete the construction of the folded-plate roof A (see Figures 4 and 5). Figure 11 shows an embodiment in which the tongue of the retaining clip 5 is placed over the angle-shaped semicircular section 12c of the lower run section 12, and the upper run section 13 to which the buffer seal 2 is bonded is clamped, forming the clamping section.

[0065] In the above construction process, the buffer seal 2 is securely fixed in place by the adhesive between the cushion seal 2 and the neck 13a of the upper rung portion 13, and in the process of overlapping the lower rung portion 12 of the corrugated roof panel 1 with the upper rung portion 13 of another adjacent corrugated roof panel 1, the outward protrusion 21 of the cushion seal 2 is a non-adhesive area and bends freely along the outside of the lower rung portion 12, and the outward protrusion 21 deforms to roughly follow the outer surface shape of the lower rung portion 12 (see Figure 1(B) and Figure 4(3)).

[0066] In addition, by properly fastening the lower rung portion 12 and the upper rung portion 13, the buffer seal 2 is clamped so that it is in close contact with both the outer surface of the lower rung portion 12 and the back surface of the upper rung portion 13, thereby preventing direct contact between the lower rung portions 12 and the upper rung portions 13 of adjacent corrugated roof panels 1, 1, resulting in a corrugated roof A that can prevent the panel squealing phenomenon [see Figure 5 (7)].

[0067] In the present invention, the entire width of the buffer seal 2 is not adhesively bonded across the entire back surface of the upper run portion 13 in the width direction, but only one end (one side) of the buffer seal 2 in the width direction (X direction) is adhered to the neck portion 13a (or outer end piece 13e) of the upper run portion 13. As a result, the outer protrusion 21 is a non-adhesive area and a free portion, and can be clamped between the lower run portion 12 and the upper run portion 13 in an extremely efficient manner during the fastening process without accidentally adhering to the upper run portion 13.

[0068] Thus, in the construction process of the present invention, the upper run portion 13 of the next-position folded-plate roof panel 1 is placed over the lower run portion 12 of the previous-position folded-plate roof panel 1 that has already been installed in the specified position, and the outward protrusion 21 of the buffer seal 2 adhered to the upper run portion 13 of the previous-position folded-plate roof panel 1 is pushed down, causing the lower run portion 12 and the upper run portion 13 to overlap, and the buffer seal 2 is interposed between the lower run portion 12 and the upper run portion 13. After that, by fastening the lower run portion 12 and the upper run portion 13 with the fastening machine 6, a folded-plate roof A can be easily and quickly constructed, with the buffer seal 2 interposed between the lower run portion 12 and the upper run portion 13 between adjacent folded-plate roof panels 1, 1.

[0069] Conventionally, a buffer seal was attached to either the lower or upper rung along its entire surface, and this work had to be done very carefully and accurately. Therefore, attaching the buffer seal to the lower or upper rung was extremely tedious, and required a certain level of technical skill from the worker. The present invention allows the construction of a folded-plate roof A of the same quality as the folded-plate roof A, which can prevent or reduce the clunking phenomenon caused by the conventional process, without being affected by the worker's technical ability, and it can shorten the work time and reduce the labor burden on the worker.

[0070] Next, a second embodiment of the present invention will be described. In this second embodiment, the widthwise end of the buffer seal 2 is bonded only to the back surface of the outer end piece 13e of the upper running portion 13 (see Figs. 6(A) and (B)). Here, the outer end piece 13e is a part of the running portion 13d, and the bonding area of ​​the buffer seal 2 with the outer end piece 13e also includes the outer portion of the running portion 13d (see Figs. 6(A) and 7).

[0071] The portion of the cushioning seal 2 that protrudes inward in the width direction (X direction) of the upper running portion 13, other than the adhesive area between the width direction end of the cushioning seal 2 and the back surface side of the outer end piece 13e of the upper running portion 13, is a non-adhesive region, namely an inward protrusion 22 (see Fig. 6(A)). The inward protrusion 22 protrudes from the outer end piece 13e toward the inner side of the upper running portion 13 so that its cross section in the width direction (X direction) hangs down in a substantially inverted U shape (see Figs. 6(A) and 7).

[0072] In this second embodiment, as described above, the outer end piece 13e is the outer tip portion of the folded portion 13d in the width direction (X direction), and is a part that constitutes the outer tip of the folded portion 13d. The outer end piece 13e is a thin flat surface that extends along the longitudinal direction (Y direction) of the folded plate roof panel 1, and the end of the buffer seal 2 in the width direction (X direction) is adhesively joined to the back side of the outer end piece 13e.

[0073] In the second embodiment, when an adhesive portion 2k is provided on the buffer seal 2, the range of the adhesive portion 2k in the width direction (X direction) of the buffer seal 2 is the portion of any one side end of the buffer seal 2 in the width direction (X direction), and the dimension of the range of this adhesive portion 2k in the width direction (X direction) is set to be equal to or approximately equal to the length dimension L5 of the outer end piece 13e of the upper running portion 13 (see Figures 6(A) and 7).

[0074] In the second embodiment, the buffer seal 2 has a widthwise (X-direction) length Lo that is equal to or greater than the length of a cross section perpendicular to the longitudinal direction (Y-direction) of the upper running portion 13, i.e., the length along the outer shape of the widthwise (X-direction) and on the back surface side of the upper running portion 13 from the lower end of the neck portion 13a along the back surface to the outer end of the upper running portion 13 (i.e., the outer end piece 13e) (see Figs. 6(A) and 7). More specifically, the widthwise (X-direction) length Lo of the buffer seal 2 is equal to or greater than the widthwise (X-direction) length Lp of the upper running portion 13 on the back surface side of the widthwise (X-direction). In other words, the length Lo of the buffer seal 2 is set slightly larger than the length Lp of the upper running portion 13.

[0075] That is, in the second embodiment of the present invention, as in the first embodiment, the width direction dimension Lo of the buffer seal 2 is equal to or greater than the length dimension Lp, which is the sum of the length dimension L4 of the wound portion 13d, the length dimension L3 of the half-mountain-shaped portion 13c, the length dimension L2 of the folded piece 13b, and the length dimension L1 of the neck portion 13a, in a cross section perpendicular to the width direction (X direction) of the upper running portion 13 (see FIGS. 6(A) and 7). As described above, in the second embodiment, the buffer seal 2 is configured so that the inward protrusion 22 gradually hangs down from the wound portion 13d of the upper running portion 13 toward the inward side of the upper running portion 13 in the width direction (X direction) (see FIG. 6(A)).

[0076] Next, a construction method for a folded-plate roof A will be described in the second embodiment of the present invention. The construction method in the second embodiment of the present invention is substantially the same as that in the first embodiment. First, a buffer seal 2 is adhered to the outer end of the upper rung portion 13 of the folded-plate roof panel 1, i.e., the back side of the outer end piece 13e, along the longitudinal direction (Y direction) of the upper rung portion 13 (see Figures 6(A) and 7). The end (assuming one side portion) of the buffer seal 2 adhesively joined to the back side of the outer end piece 13e of the upper rung portion 13 protrudes inward in the width direction (X direction) of the upper rung portion 13, and as described above, this portion is the inward protruding portion 22 that is the non-adhesive region of the upper rung portion 13 (see Figures 6(A) and 7).

[0077] Then, in the same manner as in the first embodiment, the upper run portion 13 of the next-position folded plate roof panel 1 is placed over the lower run portion 12 of the existing (previous position) folded plate roof panel 1 (see Figure 6(B)). In the process of placing the upper run portion 13 of the next-position folded plate roof panel 1 over the lower run portion 12 of the previous-position folded plate roof panel 1, the inward protruding portion 22, which is the non-adhesive area portion of the buffer seal 2 adhesively bonded to the back side of the outer end piece 13e of the upper run portion 13 of the next-position folded plate roof panel 1, comes into contact with the mountain-shaped semicircular portion 12c of the lower run portion 12 of the previous-position folded plate roof panel 1, and the upper run portion 13 of the next-position folded plate roof panel 1 is pushed down.

[0078] The inward protrusion 22, which is the pressed-down non-adhesive region of this buffer seal 2, is interposed between the upper run portion 13 and the lower run portion 12, and follows the shapes of the two folded pieces 12b, 13b and the two neck portions 12a, 13a, so as to be sandwiched between the two folded pieces 12b, 13b and the two neck portions 12a, 13a. The upper run portion 13 of the next folded plate roof panel 1 has been completely placed over the lower run portion 12 of the previous folded plate roof panel 1, and the buffer seal 2 is properly interposed between the lower run portion 12 and the upper run portion 13, which are in the middle of the fastening process before fastening. In this state, the fastening machine 6 is placed at the longitudinal ends (Y direction) of the lower run portion 12 and the upper run portion 13, and the lower run portion 12 and the upper run portion 13 before fastening are sandwiched between the receiving roll 63 of the fastening machine 6 and the corresponding pressing roll 62 (see Figure 6(C)).

[0079] The clamping machine 6 is started, the receiving roll 63 and the pressing roll 62 rotate, and the clamping machine 6 moves the overlapping part of the lower run portion 12 and the upper run portion 13 along the longitudinal direction (Y direction), thereby clamping the lower run portion 12 of the adjacent existing folded plate roof panel 1 at the previous position to the upper run portion 13 of the folded plate roof panel 1 at the next position to be installed (see Figure 6 (C)). Then, the folded plate roof panel 1 at the next position becomes the folded plate roof panel 1 at the previous position, and a buffer seal 2 is adhered to the upper run portion 13 of the adjacent folded plate roof panel 1 at the next position, and by repeating this process in the same way, the folded plate roof A is constructed.

[0080] In the second embodiment of the present invention, the mountain-shaped semicircular portion 12c of the lower run portion 12 also has variations 1 and 2 depending on the position of the recessed portion 12d. In variation 1, the recessed portion 12d is formed at the outer end of the mountain-shaped semicircular portion 12c in the width direction (X direction) (see FIGS. 9(A) and 9(B)). In variation 2, the recessed portion 12d is formed at the inner end of the mountain-shaped semicircular portion 12c in the width direction (X direction) (see FIGS. 9(C) and 9(D)). Variations 1 and 2 of the second embodiment are similar to those of the first embodiment, and the recessed portion 12d is formed in a generally L-shape or a generally inverted L-shape.

[0081] Next, a third modification of the lower running portion 12 of the present invention will be described with reference to Figures 8(E), (F) and 9(E), (F). This modification is applicable to the first and second embodiments of the present invention. In this third modification, the mountain-shaped semicircular portion 12c of the lower running portion 12 of the first and second modifications is replaced with a triangular mountain-shaped portion 12f. In this third modification of the lower running portion 12, the lower running portion 12 has a vertically rising neck portion 12a, a bent piece 12b formed at the upper end of the neck portion 12a extending inward in the width direction, a right-angled triangular mountain-shaped portion 12f formed at the inner end of the bent piece 12b in the width direction (X direction), and an outer end piece 12g formed outward in the width direction (X direction) of the triangular mountain-shaped portion 12f.

[0082] The cross section of the outer end piece 12g in the width direction (X direction) is approximately L-shaped (see Figures 8(E), (F), 9(E), (F)). In the third modified example of the lower running portion 12, the upper running portion 13 of the folded-plate roof panel 1 has the same shape as the upper running portion 13 in the first and second embodiments. The triangular mountain-shaped portion 12f in the third modified example of the lower running portion 12 is included in the concept of the mountain-shaped semicircular portion 12c of the lower running portion 12 in the first and second embodiments. Furthermore, the outer end piece 12g in the third modified example of the lower running portion 12 is included in the concept of the recessed portion 12d of the lower running portion 12 in the first and second embodiments.

[0083] The buffer seal 2 is then bonded to the neck portion 13a of the upper running portion 13. More specifically, the widthwise end of the buffer seal 2 is bonded near the lower end of the neck portion 13a of the upper running portion 13 (see Figure 8(C)). The buffer seal 2 does not necessarily have to be bonded to the entire surface of the neck portion 13a. The lower end of the neck portion 13a of the upper running portion 13 is continuously formed with the rising apex 11c of the main plate 11. The lower end portion of the neck portion 13a is formed in a substantially arc shape, and this arc-shaped portion at the lower end is also part of the neck portion 13a. The widthwise (X-direction) end of the buffer seal 2 is adhesively joined to the arc-shaped portion at the lower end of the neck portion 13a.

[0084] Next, the tensioning machine 6 used in the present invention will be described with reference to Figure 10. The tensioning machine 6 is a device that performs tensioning processing while clamping the buffer seal 2 between the lower tension portion 12 and the upper tension portion 13 of adjacent folded-plate roof panels 1,1 during the construction of a folded-plate roof A. The tensioning machine 6 is composed of a mechanism housing 61, multiple support rolls 63, and the same number of pressure rolls 62 as the support rolls 63.

[0085] The mechanism housing 61 houses a gear mechanism and an electric motor that drives the gear mechanism (not shown). A plurality of pressing rolls 62, 62, ... are configured to rotate in the same direction via the electric motor and the gear mechanism. Specifically, three backing rolls 63 and three pressing rolls 62 are installed in series, and the row of backing rolls 63 and the row of pressing rolls 62 are arranged in parallel (see FIG. 10(C)).

[0086] The row of pressure rolls 62, 62, ... can be set to a close state or a separated state by operating the operating lever 61a relative to the row of support rolls 63, 63, .... The state in which the row of pressure rolls 62, 62, ... and the row of support rolls 63, 63, ... are separated by a relatively large distance occurs when the crimping machine 6 is to be installed on the lower and upper run sections 12 and 13 to be crimped, and when the crimping machine 6 is to be removed from the lower and upper run sections 12 and 13 that have already been crimped.

[0087] Furthermore, when performing the fastening process between the lower fastening portion 12 and the upper fastening portion 13, the backing roll 63 and the pressure roll 62 are brought into close proximity to each other. In each row of backing rolls 63 and pressure rolls 62, the backing rolls 63 and pressure rolls 62 on both sides in the front-rear direction act as guides, and the central backing roll 63 and pressure roll 62 perform the actual fastening process.

[0088] Thanks to the receiving roll 63 and the pressure roll 62 that act as guides on both the front and rear sides of the tightening machine 6, the front and rear sides in the front and rear direction are not specifically determined, and it can be installed at the overlapping point between the lower tightening portion 12 and the upper tightening portion 13 of adjacent corrugated roof panels 1, 1 without considering the front and rear direction.

[0089] In the construction method of the present invention, the buffer seal 2 is attached to the upper rung portion 12 of the folded-plate roof panel 1 at the construction site of the folded-plate roof A. However, when constructing a relatively small folded-plate roof A, the length of the folded-plate roof panel 1 in the longitudinal direction (Y direction) may be shortened, and in such cases, the buffer seal 2 may be attached to the folded-plate roof panel 1 in advance at the factory before delivery to the site.

[0090] Next, we will outline the folded-plate roof A constructed in accordance with the first embodiment of the present invention. The roof is equipped with a folded-plate roof panel 1 having a lower rung 12 on one side of the width of the main panel 11, with a bent piece 12b formed from the upper end of a vertical neck 12a extending inward in the width direction and a semicircular mountain-shaped portion 12c with a recess 12d extending outward from the inner end of the bent piece 12b, and an upper rung 13 on the other side of the width of the main panel 11, with a bent piece 13b formed from the upper end of a vertical neck 13a extending inward in the width direction and a semi-mountain-shaped portion 13c extending outward from the inner end of the bent piece 13b and a rolled-up portion 13d formed at the edge of the semi-mountain-shaped portion 13c, and a buffer seal 2.

[0091] The widthwise length of the buffer seal 2 is set to be equal to or greater than the length along the outer contour of a cross section perpendicular to the longitudinal direction of the upper running portion 13, and extending from the lower end of the neck portion 13a on the back side of the upper running portion 13 along the back surface to the outer end of the upper running portion 13. The widthwise end of the buffer seal 2 is bonded only to the neck portion 13a of the upper running portion 13, and a non-bonded region that protrudes outward in the width direction of the upper running portion 13 other than the bonded portion of the buffer seal 2 to the neck portion 13a of the upper running portion 13 is set to be an outward protruding portion 21. The buffer seal 2 is interposed between the lower running portion 12 and the upper running portion 13, and the lower running portion 12 and the upper running portion 13 are fastened together to construct a folded-plate roof.

[0092] Next, we will outline a folded-plate roof A constructed in accordance with the second embodiment of the present invention. The roof is equipped with a folded-plate roof panel 1 having a lower rung 12 on one side of the width of the main panel 11, with a bent piece 12b formed from the upper end of a vertical neck 12a extending inward in the width direction and a semicircular mountain-shaped portion 12c with a recess 12d extending outward from the inner end of the bent piece 12b, and an upper rung 13 on the other side of the width of the main panel 11, with a bent piece 13b formed from the upper end of a vertical neck 13a extending inward in the width direction and a semi-mountain-shaped portion 13c extending outward from the inner end of the bent piece 13b, with a rolled-up portion 13d formed at the edge of the semi-mountain-shaped portion 13c, and a buffer seal 2.

[0093] The widthwise length of the buffer seal 2 is set to be equal to or greater than the length along the outer contour of a cross section perpendicular to the longitudinal direction of the upper running portion 13, and extending from the lower end of the neck portion 13a on the back surface of the upper running portion 13 along the back surface to the outer end of the upper running portion 13. The widthwise end of the buffer seal 2 is bonded only to the outer end of the upper running portion 13, and a non-bonded region that protrudes inward in the width direction of the upper running portion 13 other than the bonded portion of the buffer seal 2 to the outer end of the upper running portion 13 is set to be an inward protruding portion 22. The buffer seal 2 is interposed between the lower running portion 12 and the upper running portion 13, and the lower running portion 12 and the upper running portion 13 are fastened together to construct a folded-plate roof.
