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. [Means for solving the problem]

[0010] Therefore, the inventor has conducted extensive research to solve the above problems, and as a result, the invention of claim 1 is a folded 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 length in the width direction of the buffer seal being along the outer shape of a cross section perpendicular to the longitudinal direction of the lower rung portion and being equal to or greater than the length from the lower end of the neck portion of the lower rung portion to the tip of the top surface portion, and the end portion on one side in the width direction of the buffer seal is bonded only to the top surface portion of the lower rung portion, and The above problem was solved by providing a construction method for a corrugated roof, which is characterized in that the non-adhesive area that protrudes outward is made the outward protruding part, and the upper run part of the adjacent corrugated roof panel is placed over the lower run part of the corrugated roof panel, while the outward protruding part of the buffer seal adhered to the top surface of the lower run part of the corrugated roof panel at the front position is pressed down so that the buffer seal is interposed between the lower run part and the upper run part, and the lower run part and the upper run part are fastened together using a fastening machine, and this process is repeated sequentially.

[0011] The above problem was solved by the invention of claim 2, which is the construction method for a folded plate roof according to claim 1, characterized in that the buffer seals are bonded along the entire longitudinal direction of the lower rung portion of the folded plate roof panel.The above problem was solved by the invention of claim 3, which is the construction method for a folded plate roof according to claim 1 or 2, characterized in that the buffer seals are bonded at predetermined intervals along the longitudinal direction of the lower rung portion of the folded plate roof panel, and the buffer seals are interposed at the locations where the retaining clips are installed.

[0012] The above problem was solved by the invention of claim 4, which is a construction method for a folded plate roof according to claim 1 or 2, characterized in that the lower rung portion is formed by an arc-shaped bulge portion that bulges outward in the width direction from the upper end of the vertical neck portion in a semicircular shape, and a top surface portion is formed from the upper end of the arc-shaped bulge portion inward in the width direction, and the upper rung portion is formed by an arc-shaped bulge portion that bulges outward in the width direction from the upper end of the vertical neck portion in a semicircular shape, and a top surface portion is formed from the upper end of the arc-shaped bulge portion outward in the width direction, and a rolled portion is formed from the outer end of the top surface portion.

[0013] The above problem was solved by the invention of claim 5, which is a construction method for a folded plate roof according to claim 1 or 2, characterized in that the lower rung portion has a horizontal top surface portion formed inward in the width direction from the upper end of the vertical neck portion, and the upper rung portion has a horizontal top surface portion formed inward in the width direction from the upper end of the vertical neck portion, and a rolled portion is formed from the outer end of the top surface portion.The above problem was solved by the invention of claim 6, which is a construction method for a folded plate roof according to claim 1 or 2, characterized in that the buffer seal is formed of foamed resin.

[0014] The invention of claim 7 is a folded roof panel having a lower rung portion formed at one upper end in the width direction of the main panel and an upper rung portion formed at the other end, and a buffer seal, the length of the buffer seal in the width direction is the same as or longer than the length from the lower end of the neck part to the tip of the top surface part of the lower rung portion along the outer shape of the cross section perpendicular to the longitudinal direction of the lower rung portion, and the end part on one side of the buffer seal in the width direction is bonded only to the top surface part of the lower rung portion, and the portion which is a non-bonded area part protruding outward in the width direction of the lower rung portion of the buffer seal is an outward protruding part, The above problem was solved by providing a construction method for a corrugated roof, which is characterized in that the area to be bonded that protrudes inward is made the inward protruding part, and the upper run part of the adjacent corrugated roof panel is placed over the lower run part of the corrugated roof panel, and the outer protruding part and the inner protruding part of the buffer seal adhered to the top surface of the lower run part of the corrugated roof panel at the front position are pushed down so that the buffer seal is interposed between the lower run part and the upper run part, and the lower run part and the upper run part are fastened together using a fastening machine, and this process is repeated sequentially.

[0015] The above problem was solved by the invention of claim 8, which is a corrugated roof comprising 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, and a buffer seal, the width direction length of the buffer seal following the outline of a cross section perpendicular to the longitudinal direction of the lower rung portion and being equal to or greater than the length from the lower end of the neck portion to the tip of the top surface portion of the lower rung portion, the end portion on one side of the width direction of the buffer seal being bonded only to the top surface portion of the lower rung portion, and the portion of the buffer seal that is a non-bonded area that protrudes outward in the width direction of the lower rung portion of the buffer seal being an outward protrusion, the buffer seal being interposed between the lower rung portion and the upper rung portion, and the lower rung portion and the upper rung portion being fastened together.

[0016] The above problem has been solved by the invention of claim 9, which is a folded plate roof construction method as set forth in claim 8, characterized in that the buffer seals are bonded along the entire longitudinal direction of the lower rung portions of the folded plate roof panels.The above problem has been solved by the invention of claim 10, which is a folded plate roof construction method as set forth in claim 8, characterized in that the buffer seals are bonded at predetermined intervals along the longitudinal direction of the lower rung portions of the folded plate roof panels, and the buffer seals are interposed at the retaining clip installation locations. [Effects of the Invention]

[0017] 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 lower rung portion and is equal to or greater than the length from the lower end of the neck portion of the lower rung portion to the tip of the top surface portion.

[0018] The buffer seal is bonded only to the top surface of the lower running portion near one end in the width direction, and the non-bonded area that protrudes 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 top surface of the lower running portion, and the other portion in the width direction of the buffer seal 2, i.e., the outward protruding portion, is a non-bonded portion to the lower running portion and can deform freely.

[0019] With the above configuration, the buffer seal is securely fixed by the adhesive point between the buffer seal and the top surface of the lower rung portion, and in the process of overlapping the lower rung portion of one adjacent corrugated roof panel with the upper rung portion of another adjacent corrugated roof panel, the outward protrusion of the buffer seal bends freely along the outer surface of the lower rung portion, and can deform to follow the shape of the outer surface of the lower rung portion.

[0020] 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.

[0021] In this way, the entire width of the buffer seal is not adhered to the lower rung portion, but only one side of the width, which is part of the buffer seal, is adhered to the top surface of the lower rung portion.As a result, the outer protrusion is a free portion, and the outer protrusion does not inadvertently adhere to the outer surface of the lower rung portion, and can be clamped extremely well between the lower rung portion and the upper rung portion during the rung processing.

[0022] As described above, by placing the upper rung portion of the next corrugated roof panel over the lower rung portion of the previous corrugated roof panel that has already been installed in the specified position and pressing down the outward protruding portion of the buffer seal adhered to the lower rung portion of the previous corrugated roof panel, when the lower rung portion and the upper rung portion are overlapped, 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 adjacent corrugated roof panels can be easily and quickly constructed.

[0023] In the past, to prevent the clunking phenomenon, the entire surface of the buffer seal was carefully and precisely bonded to the lower 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, and if this requirement is met, the work is extremely troublesome and time-consuming, and inexperienced workers often fail to bond the buffer seal to the lower rung.

[0024] The invention of claim 1 significantly simplifies the process of adhering the cushioning seal to the lower rung, and allows the construction of a corrugated roof of the same quality as a corrugated roof, which prevents or reduces the noise caused by the conventional process.It is not affected by the technical ability of the workers, improves work efficiency, shortens work time, and reduces the labor burden on workers.

[0025] In the invention of claim 2, the buffer seal is bonded to the entire longitudinal length of the lower rung of the folded-plate roof panel, which further reduces noise caused by thermal expansion and contraction. In the invention of claim 3, the amount of buffer seal to be bonded to the lower rung can be reduced, making the work easier.

[0026] In the invention of claim 4, the lower and upper run sections can be made into approximately rounded run sections, which can be used effectively for round run sections. In the invention of claim 5, the lower and upper run sections can be made into approximately square run sections with right angles, which can be used effectively for square run sections.

[0027] 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 invention of claim 7, an outward protrusion is provided on the buffer seal adhered to the top surface of the lower rung, and an inward protrusion is provided as an adhered area that protrudes inward in the width direction of the lower rung, which further reduces the contact area between the lower rung and the upper rung, further reducing noise caused by the clattering phenomenon. In the invention of claim 8, a buffer seal can be provided between the lower rung and the upper rung of adjacent folded-plate roof panels with extremely simple installation, resulting in a folded-plate roof panel that can prevent or reduce the clattering phenomenon.

[0028] In the invention of claim 9, in a folded-plate roof, the buffer seal is bonded to the entire longitudinal direction of the lower rung portion of the folded-plate roof sheet, thereby further reducing noise during thermal expansion and contraction. In the invention of claim 10, in a folded-plate roof, the amount of buffer seal bonded to the lower rung portion can be reduced, making the work easier. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0030] An embodiment of the present invention will be described below with reference to the drawings. The present invention relates to a construction method for a folded-plate roof A equipped with a structure for preventing plate noise, and to the folded-plate roof A. The folded-plate roof of the present invention 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 members 3 such as purlins and furring strips are provided (see Figure 9).

[0031] 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 9. Alternatively, as shown in Figure 6(C), it may 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. In Figure 6(C), reference numeral 41 denotes an intermediate support that supports the upper-layer folded plate roof A on top of the lower-layer folded plate roof A.

[0032] For ease of explanation, the folded plate roof panel 1 is defined as having 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 ridge 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 (see Figure 9).

[0033] The folded-plate roof panel 1 is of a fastening type, with a lower fastening portion 12 formed at one end of each widthwise (X-direction) end 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 widthwise ends of the bottom 11a, 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 each rising peak 11c and an upper fastening portion 13 formed on the other side (see Figure 2(A)).

[0034] 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 bottom 11a and both rising top portions 11c form a roughly inverted trapezoid shape, and the main plate 11 has a deep or shallow valley shape depending on the height of both rising side portions 11b.

[0035] As shown in Figure 1, the lower running portion 12 and the upper running portion 13 have a generally semicircular arc-shaped portion when viewed overall, forming a rounded shape (see Figure 1(A)). The lower running portion 12 has a neck portion 12a, an arc-shaped bulge portion 12b, and a top surface portion 12c. The neck portion 12a is a vertically rising portion (see Figures 1(A), 2(B), and (C)).

[0036] The arc-shaped bulge 12b is a portion that bulges outward in the width direction (X direction) of the lower running portion 12 from the upper end of the neck portion 12a in a roughly semicircular arc shape (see FIGS. 1(A), 2(B), and 2(C)). Here, the outer side of the width direction (X direction) of the lower running portion 12 refers to the side where the main plate 11 is not present, relative to the top surface 12c of the lower running portion 12 (see FIGS. 1 and 2(A)). In other words, in FIG. 2(B), the right side of the top surface 12c of the lower running portion 12 is the outer side of the width direction (X direction) of the lower running portion 12. Furthermore, the inner side of the width direction (X direction) of the lower running portion 12 refers to the side where the main plate 11 is present, relative to the top surface 12c of the lower running portion 12 (see FIGS. 1 and 2(A)). That is, in FIG. 2(B), the left side of the top surface 12c of the lower running portion 12 is defined as the inner side in the width direction (X direction) of the lower running portion 12.

[0037] The top surface 12c is formed as a generally horizontal, long, rectangular, flat surface at the upper end of the arcuate bulge 12b and extending inward in the width direction of the lower rung portion 12. The boundary between the arcuate bulge 12b and the top surface 12c is continuous and gradually changes from an arcuate surface to a flat surface (see FIGS. 1(A), 2(B), and (C)).

[0038] The top surface 12c may be formed as an inclined surface that rises slightly inward in the width direction. The inner end of the top surface 12c is the tip of the top surface 12c, and a folded edge 12d is formed downward from the tip. The folded edge 12d prevents the inner end (tip) of the top surface 12c from having a sharp shape (see Figures 2(B) and (C)).

[0039] Similar to the lower running portion 12, the upper running portion 13 has a neck portion 13a, an arc-shaped bulge portion 13b, a top surface portion 13c, and a wound portion 13d (see Figures 1(A), 2(A), and 3(C)). 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 to be equal to or slightly lower than the neck portion 12a of the lower running portion 12. The arc-shaped bulge portion 13b is a portion formed in a substantially semicircular arc that bulges outward from the upper end of the neck portion 13a toward the widthwise inward side of the upper running portion 13. The widthwise inward side of the upper running portion 13 refers to the side of the main plate 11 on which the upper running portion 13 is formed.

[0040] The arcuate bulge 13b of the upper running portion 13 is formed with a slightly larger radius of curvature than the arcuate bulge 13b of the lower running portion 12, so that the arcuate bulge 13b of the upper running portion 13 can overlap the arcuate bulge 12b of the lower running portion 12 in an embracing state (see FIG. 1). Furthermore, since the buffer seal 2, which will be described later, is sandwiched between the arcuate bulge 12b of the lower running portion 12 and the arcuate bulge 13b of the upper running portion 13, the radius of curvature of the arcuate bulge 13b of the upper running portion 13 is formed taking into account the thickness of the buffer seal 2.

[0041] The top surface 13c of the upper running portion 13 is formed as a generally horizontal flat surface at the upper end of the arcuate bulge 13b and facing outward in the width direction of the upper running portion 13. The top surface 13c of the upper running portion 13 is a portion that overlaps the top surface 12c of the lower running portion 12 in the vertical direction so as to sandwich the buffer seal 2 (see Figures 4(1) to 4(3)). Furthermore, a wound portion 13d is formed from the tip of the top surface 13c of the upper running portion 13 (i.e., the tip) (see Figures 1(A), 2(A), and 3(C)).

[0042] 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.

[0043] The buffer seal 2 and the lower running portion 12 are bonded together by providing an adhesive adhesive portion 2k in advance at the portion where the buffer seal 2 and the top surface 12c of the lower running portion 12 are to be bonded (see FIGS. 3(A) and (B)). The adhesive portion 2k is provided linearly along the longitudinal direction of the buffer seal 2. Alternatively, the adhesive portion 2k may be provided on the top surface 12c side of the lower running portion 12.

[0044] 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 adhered to the lower rung portion 12 of the folded-plate roof panel 1, the release paper is peeled off, and the buffer seal 2 is adhesively fixed to the top surface portion 12c of the lower rung portion 12.

[0045] The buffer seal 2 is properly bonded to the top surface 12c of the lower running portion 12 when the longitudinal direction of the buffer seal 2 is aligned with the longitudinal direction of the lower running portion 12 and the width direction of the buffer seal 2 is adhesively bonded to the top surface 12c of the lower running portion 12 (see FIG. 3(B)). The area where the buffer seal 2 is adhered to the top surface 12c of the lower running portion 12 can be either the entire longitudinal direction (Y direction) of the top surface 12c (see FIG. 6(A)), or a partial region of the top surface 12c in the longitudinal direction (Y direction) (see FIG. 6(B)). In the case of the embodiment where the buffer seal 2 is adhered to a partial region of the top surface 12c in the longitudinal direction (Y direction), the buffer seal 2 needs to be attached to the region of the top surface 12c that is fixed by the retaining clip 5.

[0046] The buffer seal 2 is bonded only to the top surface 12c of the lower running portion 12 near one end in the width direction (X direction). When the buffer seal 2 is bonded to the top surface 12c of the lower running portion 12, the buffer seal 2 is bonded so that the other side in the width direction (X direction) of the buffer seal 2 protrudes outward in the width direction of the lower running portion 12 (see Figures 1(A) and 3(B)).

[0047] The portion of the cushioning seal 2 that protrudes outward from the lower running portion 12 is referred to as the outward protrusion 21, which serves as the adhered region. The outward protrusion 21 is a portion that protrudes from the outer edge of the top surface 12c in the width direction (X direction). The portion of the lower running portion 12 that protrudes inward in the width direction (X direction), which serves as the adhered region, is referred to as the inward protrusion 22. The portion of the inward protrusion 22 that protrudes from the inner edge of the top surface 12c in the width direction (X direction) is small, and it is sufficient if it can cover the folded edge 12d of the lower running portion 12.

[0048] The buffer seal 2 is adhered to the lower running portion 12 so that the total width of the outward protrusion 21 is approximately equal to the total length L2 of the arcuate bulge 12b of the lower running portion 12 and the total length L1 of the neck portion 12a. The outward protrusion 21 has a portion that is not provided with adhesive, glue, double-sided adhesive tape, etc., and is an area that is only in contact with the lower running portion 12 and the upper running portion 13 but is not adhered, and is shown as a non-adhesive area in Figures 1(A), 2(B), and (C). The non-adhesive area of ​​the buffer seal 2 has the same concept as the outward protrusion 21.

[0049] In the buffer seal 2, the outward protrusion 21 is a non-adhesive area, an area where no adhesive is applied, and the outward protrusion 21 simply comes into contact with the lower rung portion 12 and the upper rung portion 13, but is not bonded with adhesive. In other words, since the outward protrusion 21 is a non-adhesive area, it can deform freely.

[0050] The outer protrusion 21 of the buffer seal 2 is positioned so as to contact the outer surface of the arc-shaped bulge 12b and the neck 12a, and is configured so that the lower end of the outer protrusion 21 approximately coincides with the lower end of the neck 12a of the lower running portion 12 and the lower end of the neck 13a of the upper running portion 13 (see Figures 2(B) and (C)).

[0051] As described above, the buffer seal 2 is strip-shaped, and its width dimension is set to be larger than the width dimension of the top surface 12c of the lower running portion 12. The width dimension (X direction) of the buffer seal 2 is slightly larger than the length dimension along the outline of a cross section perpendicular to the longitudinal direction of the lower running portion 12. In other words, the width dimension Lo of the buffer seal 2 is set to be slightly longer than the length along the outline of a cross section perpendicular to the longitudinal direction of the lower running portion 12, and the inward protrusion 22 may be configured to protrude slightly beyond the tip of the top surface 12c of the lower running portion 12 (see Figure 2(B)).

[0052] More specifically, the width direction dimension Lo of the buffer seal 2 is equal to or greater than the sum of the length dimension L1 of the neck portion 12a, the length dimension L2 of the arcuate bulge portion 12b, the length dimension L3 of the top surface portion 12c, and the length dimension L4 of the folded edge 12d in a cross section perpendicular to the longitudinal direction of the lower run portion 12 (see Figure 2(B)). That is, Lo≧L1+L2+L3+L4, and is set to be equal to or slightly larger than the overall length of the cross section of the lower running portion 12 perpendicular to the longitudinal direction (see FIG. 2(B)).

[0053] The buffer seal 2 may be bonded only to the neck 12a, arcuate bulge 12b, and top surface 12c of the lower rung portion 12, without contacting the folded edge 12d (see Fig. 2(C)). In this case, the width direction dimension Lo of the buffer seal 2 is set equal to or slightly larger than the sum of the length dimension L1 of the neck 12a, the length dimension L2 of the arcuate bulge 12b, and the length dimension L3 of the top surface 12c. In other words, Lo≧L1+L2+L3 (see FIG. 2(C)).

[0054] 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, and does not protrude from the lower run portion 12 or the upper run portion 13 (see Fig. 1(C) and Fig. 5(7)). Also, the lower run portion 12 may be slightly above 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.

[0055] Next, we will explain the construction method of the folded plate roof A of the present invention. Here, in the explanation, the terms previous position and next position are used in the process of constructing the folded plate roof A using the folded plate roof panel 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 once installed.

[0056] First, the buffer seal 2 is adhered along the longitudinal direction to the top surface 12c of the lower rung portion 12 of the folded-plate roof panel 1 (see Figures 3(A) and (B)). One side portion of the buffer seal 2 adhered to the top surface 12c of the lower rung portion 12 in the width direction (X direction) protrudes outward in the width direction of the lower rung portion 12, and as mentioned above, this portion is the outward protruding portion 21 that is a non-adhesive region with respect to the lower rung portion 12 (see Figures 1(A) and 3(B)).

[0057] In this way, the buffer seal 2 is adhered to the predetermined location of the folded plate roof panel 1 so as to satisfy the above-mentioned configuration, 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 construction site of the folded plate roof A of the building (see Figure 6(C)). Next, the upper run portion 13 of the next 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) folded plate roof panel 1 from above (see Figure 4(1)).

[0058] 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 as to cover 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 relative to the lower run portion 12 of the previous position, with the lower run portion 12 as the rotation center, so that the upper run portion 13 covers the lower run portion 12.

[0059] In the process of covering the lower running portion 12 of the previous folded roof panel 1 with the upper running portion 13 of the next folded roof panel 1, the outward protruding portion 21, which is the non-bonded area portion and free of the buffer seal 2 bonded to the top surface portion 12c of the lower running portion 12 of the previous folded roof panel 1, is pushed down by the upper running portion 13 of the next folded roof panel 1 (see Figure 4 (2)).

[0060] 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 follows the shapes of the arcuate bulges 12b, 13b and the neck portions 12a, 13a, so as to be sandwiched between the arcuate bulges 12b, 13b and the neck portions 12a, 13a (see Figure 3(4)).

[0061] 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)).

[0062] Then, the clamping machine 6 is started, and the receiving roll 63 and the pressing roll 62 rotate, and the clamping machine 6 moves the overlapping portion of the lower and upper run portions 12 and 13 along the longitudinal direction (Y direction) [see Figure 5 (6)]. As a result, the lower run portion 12 of the adjacent, already installed folded-plate roof panel 1 at the previous position and the upper run portion 13 of the folded-plate roof panel 1 at the next position to be installed are clamped together [see Figure 5 (7)]. 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 predetermined position of the adjacent folded-plate roof panel 1 at the next position. By repeating this process in the same way, the folded-plate roof A is constructed (see Figure 9).

[0063] In the above construction method, the buffer seal 2 is adhered to the folded plate roof panel 1, and then the folded plate roof panel 1 is placed and fixed via structural members 3 such as beams, brackets 4, and retaining clips 5, etc., installed at the construction location of the folded plate roof A of the building. However, this is not necessarily limited to this, and although not shown, the procedure may be such that the folded plate roof panel 1 is placed on the structural members 3 via the brackets 4 and retaining clips 5, and then the buffer seal 2 is adhered to the folded plate roof panel 1. Figure 9(B) shows an embodiment in which the buffer seal 2 is adhered to the top surface 12c of the lower rung portion 12, and the tongue of the retaining clip 5 is placed on the top surface of the buffer seal 2 to form a rung fastening portion.

[0064] In the above construction process, the buffer seal 2 is securely fixed in place by the adhesive points between the buffer seal 2 and the top surface 12c of the lower rung portion 12, and in the process of overlapping the lower rung portion 12 of a corrugated roof panel 1 with the upper rung portion 13 of another adjacent corrugated roof panel 1, the outward protrusion 21 of the buffer seal 2 is a non-adhesive area and bends freely along the outer surface of the lower rung portion 12, and the outward protrusion 21 deforms to follow the shape of the outer surface of the lower rung portion 12 (see Figure 1(B)).

[0065] 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.

[0066] In the present invention, the entire width of the buffer seal 2 is not adhered to the lower rung portion 12, but only one side of the buffer seal 2 in the width direction, which is a part of the buffer seal 2, is adhered to the top surface portion 12c of the lower rung portion 12. As a result, the outer protrusion 21 is a non-adhesive area and a free portion, and can be clamped extremely well between the lower rung portion 12 and the upper rung portion 13 during the rung processing without accidentally adhering to the lower rung portion.

[0067] 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, which has already been installed in the specified position. By pressing down the outer protrusion 21 and the inner protrusion 22 of the buffer seal 2 adhered to the lower run portion 12 of the previous-position folded-plate roof panel 1, the lower run portion 12 and the upper run portion 13 are overlapped, 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 with a buffer seal 2 interposed between the lower run portion 12 and the upper run portion 13 between adjacent folded-plate roof panels 1, 1 can be easily and quickly constructed.

[0068] 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.

[0069] Figure 7 shows another embodiment of the folded-plate roof panel 1, in which the fastening portion is vertically fastened. The lower fastening portion 12 has a vertically rising neck portion 12a, and a horizontal top surface portion 12c extending inward in the width direction at the upper end of the neck portion 12a. Similarly to the lower fastening portion 12, the upper fastening portion 13 has a horizontal top surface portion 13c extending outward in the width direction at the upper end of the neck portion 13a. A rolled end portion 13d is formed from the outer end of the top surface portion 13c.

[0070] Next, the tensioning machine 6 used in the present invention will be described with reference to Figure 8. 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.

[0071] The mechanism housing 61 houses a gear mechanism and an electric motor that drives the gear mechanism, not shown. The electric motor and the gear mechanism rotate a plurality of pressing rolls 62, 62, ... in the same direction. Specifically, three backing rolls 63 and three pressing rolls 62 are mounted in series, and the row of backing rolls 63 and the row of pressing rolls 62 are arranged in parallel.

[0072] 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 receiving rolls 63, 63, .... The state in which the row of pressure rolls 62, 62, ... and the row of receiving rolls 63, 63, ... are separated occurs when the crimping machine 6 is to be installed on the lower and upper running portions 12 and 13 to be crimped, and when the crimping machine 6 is to be removed from the lower and upper running portions 12 and 13 that have already been crimped.

[0073] 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.

[0074] 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.

[0075] In the construction method of the present invention, the buffer seal 2 is attached to the lower run 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.
