Description

[[Technical Field]]

[0001] The present invention relates to a roof support and a double-layer folded plate roof, which is installed between a lower-layer folded plate roof and an upper-layer folded plate roof in a double-layer folded plate roof, can be simply, quickly and firmly attached to the lower-layer folded plate roof, and can extremely firmly support the upper-layer folded plate roof panels. [[Background Art]]

[0002] Conventionally, double-layer folded plate roofs (including steeply inclined walls and the like) constructed by a lower-layer folded plate roof and an upper-layer folded plate roof have been constructed. In particular, in response to recent weather conditions and the strengthening of countermeasures against global warming and energy saving, demand for double-layer folded plate roofs has been increasing for metal roofs depending on the application of the building. These roofs include newly constructed double-layer roofs and renovated roofs where a new roof is newly installed over an existing roof. The lower-layer folded plate roof is constructed from metal folded plate roof panels. Additionally, among folded plate roofs, there are also many that are constructed as substantially wall-shaped at a steep inclination, and there exist many folded plate roofs of this type.

[0003] Among this type of double-layer roof, those constructed from folded plate roof panels having a lower seam and an upper seam are widely used. In many constructions, the lower seam and upper seam of adjacent folded plate roof panels are seamed together to connect the folded plate roof panels to one another and construct the folded plate roof or the like. A support is provided between the upper-layer folded plate roof and the lower-layer folded plate roof, the support is mounted on the lower-layer folded plate roof, and the upper-layer folded plate roof is supported on the lower-layer folded plate roof by said support.

[0004] In this seam-type folded plate roof, many designs have emerged in which the support is installed on the lower-layer folded plate roof by utilizing the seamed portion of the lower-layer folded plate roof. As an example of this type, Patent Document 1 (Japanese Unexamined Patent Application Publication 20 03-49510) is cited. The fixing bracket of Patent Document 1 is attached in a locked state to a joining convex portion such as a seamed portion of an outer enclosure of a lower layer of an outer enclosure such as a folded plate roof, and an upper-layer outer enclosure is constructed on this fixing bracket. layer of an outer enclosure of a joining convex portion such as a seamed portion of an outer enclosure of a lower layer of an outer enclosure such as a folded plate roof, and an upper-layer outer enclosure is constructed on this fixing bracket.

[0012] The invention of claim 7 comprises a two-layer corrugated metal roof consisting of a lower corrugated metal roof material having risen portions formed on both sides in the width direction of the main plate, and a plurality of corrugated metal roof material having fitted bend portions formed at the midpoint in the height direction of both risen portions, arranged in parallel and connected, and an upper corrugated metal roof having the same configuration as the lower corrugated metal roof using corrugated metal roof material equivalent to that of the lower corrugated metal roof, and a first clamping member having a first head with an outer end that is a first fitted edge, and a first leg that extends downward in an inclined manner from the first head and has a first fastening portion in the middle and a first fitting projection at the lower end, and a second clamping member having a second head with an outer end that is a second fitted edge, and a second leg that extends downward in an inclined manner from the second head and has a second fastening portion in the middle and a second fitting projection at the lower end, and these two clamping members are pivotally connected by a pivot member that intersects in an X shape, and the first head top surface The second head top surface The above problem is solved by providing a two-layer corrugated metal roof characterized by a roof support positioned lower than the lower corrugated metal roof, the roof support being positioned on the opposing rising portions of adjacent corrugated metal roof panels in the lower corrugated metal roof, the first and second legs of the roof support engaging the fastening portion of the lower corrugated metal roof with both fitted bent portions, and a predetermined gap being provided between the opposing surfaces of the first and second heads, and a hanger for the upper corrugated metal roof being fixed on the first head to provide the upper corrugated metal roof.

[0013] The invention of claim 8 is a two-layer corrugated metal roof as described in claim 7, characterized in that a resin-coated portion is provided where resin is applied to the contact points between the first head of the first clamping member and the second head of the second clamping member and the corrugated metal roof plate, and to the portion of the first leg below the vicinity of the first locking portion and the portion of the second leg below the vicinity of the second locking portion. This solves the above problem. [Effects of the Invention]

[0014] In the invention of claim 1, the roof support is pivotally connected such that the first clamping member and the second clamping member intersect in an X-shape above the first and second clamping portions, bringing the first and second heads closer together, which narrows the distance between the first and second legs, and also narrows the distance between the first and second clamping portions and the first and second fitting projections. With respect to a two-layer corrugated metal roof having fitting bends in the lower and upper corrugated metal roofs, both fitting bends and clamping portions of the mountain-shaped portion formed by the opposing rising portions and mountain-shaped peaks of adjacent corrugated metal roof panels in the lower corrugated metal roof can be simultaneously locked and fitted.

[0015] The first head and the second head are connected by a fastening member such that there is a predetermined gap between their opposing surfaces. By tightening the fastening member, the first and second fastening parts are locked into the fastening part of the lower corrugated roof, and the first and second fitting projections are fitted into both fitting bends of the mountain-shaped part of the lower corrugated roof, thereby achieving a secure attachment.

[0016] Furthermore, the outer ends of the first head and the second head are configured as fitting edges for the two fitted bends of the mountain-shaped section of the upper corrugated metal roof, and they fit into the two fitted bends of the mountain-shaped section of the upper corrugated metal roof. In addition, the first head is positioned lower than the second head and is configured to have a hanger for fastening installed and fixed to it. When the hanger is attached to the first head on the upper corrugated metal roof, the top of the second head and the hanger base of the hanger are on approximately the same plane, and the top of the roof support becomes approximately flat. This allows the fastening section of the upper corrugated metal roof to be fixed to it without difficulty via the hanger.

[0017] Thus, the roof support in the present invention does not connect to the double-layer corrugated metal roof only through the respective fastening portions of the lower and upper corrugated metal roofs, but rather locks and fits into the fastening portion and the fitting bend portion of the lower corrugated metal roof of the double-layer corrugated metal roof, respectively. This allows the roof support in the present invention to be attached to the lower corrugated metal roof of the double-layer corrugated metal roof in a simple, quick, and extremely strong manner. Furthermore, by constructing the upper corrugated metal roof via the roof support in the present invention, an extremely strong double-layer corrugated metal roof can be constructed.

[0018] Furthermore, when a large negative pressure is applied to the upper corrugated metal roof during strong winds such as typhoons, and an external force acts that lifts the upper corrugated metal roof upward, the two fitted bent portions of the mountain-shaped part of the upper corrugated metal roof attempt to lift both fitted edges of the first and second heads of the roof support upward. At this time, the first and second heads of the roof support rotate relative to each other around the pivot connection point as the center of rotation, moving closer to each other.

[0019] Simultaneously, the first leg portion and the second leg portion rotate so as to move closer to each other around the pivot connection point. In this way, the first locking portion and the second locking portion, and the first fitting projection 2 and the first fitting projection move closer to each other, and they come into even stronger contact with the locking portion and both fitted bends of the mountain-shaped portion of the lower corrugated metal roof, locking and fitting together, so that the two-layer corrugated metal roof can sufficiently resist and withstand strong winds.

[0020] In the invention of claim 2, the first head has a fixing hole for a hanger and an internal thread member is fixed to the lower side, allowing the hanger to be attached to the first head easily and quickly. In the invention of claim 3, the first head has a fixing hole for a hanger and an internal thread is formed in the through hole, eliminating the need for a nut when attaching the hanger to the first head, reducing the number of parts and improving work efficiency.

[0021] In the invention of claim 4, the first head and the second head are provided with a first hanging piece and a second hanging piece, respectively. A connecting hole having a larger diameter than the bolt of the tightening member is formed in the first hanging piece and the second hanging piece, and an internal screw member screwed onto the bolt of the tightening member is fixedly secured to the first hanging piece. With this configuration, the first head and the second head can smoothly approach each other.

[0022] In the invention of claim 5, the first head and the second head are provided with a first hanging piece and a second hanging piece, respectively. A connecting hole having a larger diameter than the bolt of the tightening member is formed in the second hanging piece, and an internal screw thread screwed onto the bolt is formed in the connecting hole of the first hanging piece. With this configuration, a nut can be eliminated from the pivot member, the number of parts can be reduced, and working efficiency can be improved.

[0023] In the invention of claim 6, resin-coated portions coated with resin are provided at respective contact positions of the first head of the first holding member and the second head of the second holding member with the folded-plate roof panel, at portions below the vicinity of the first engaging portion of the first leg, and at portions below the vicinity of the second engaging portion of the second leg. When the roof support is used for a two-layer folded-plate roof structure, even if high-temperature or low-temperature heat is transferred from the upper folded-plate roof to the roof support, the resin-coated portion blocks heat from being transferred to the lower folded-plate roof, thereby preventing low or high temperature from being transferred to the lower folded-plate roof and the indoor space below the roof. This allows the indoor heat retention property to be always maintained without being affected by external cold and heat.

[0024] Furthermore, when the upper folded-plate roof is exposed to high temperatures such as in summer, the folded-plate roof panels constituting the upper folded-plate roof thermally expand and contract along the longitudinal direction (X direction), which causes positional displacement relative to the roof support, and may generate vibration and noise. In such cases, the resin-coated portion minimizes the generation of vibration and noise caused by positional displacement of the upper folded-plate roof relative to the lower folded-plate roof, thereby suppressing the panel squeaking phenomenon.

[0025] The invention of claim 7 allows for the simple and rapid construction of an extremely robust double-layer corrugated metal roof. The invention of claim 8 prevents heat from being transferred to the lower corrugated metal roof by the resin coating, preventing low or high temperatures from being transmitted to the lower corrugated metal roof and its interior, thus maintaining constant indoor heat retention regardless of external temperature fluctuations. Furthermore, the resin coating minimizes the generation of vibrations and noise caused by misalignment between the upper and lower corrugated metal roofs, thereby suppressing the rattling phenomenon.

[Modes for carrying out the invention]

[0027] The following describes embodiments of the roof support A and the double-layer corrugated metal roof B using the roof support A of the present invention with reference to the drawings. First, the roof support A of the present invention will be described, and then the double-layer corrugated metal roof B using the roof support A will be described. The roof support A is mainly suitable for use with the double-layer corrugated metal roof B, which is mainly composed of corrugated metal roofing sheets (see Figure 1). In particular, the roof support A is suitable for use with the mortise and tenon type corrugated metal roof.

[0028] In this invention, the terms X direction and Y direction are used to indicate direction. In a double-layer corrugated metal roof B constructed using the roof support A of this invention, the direction in which the multiple corrugated metal roof panels 8, 8, ... constituting the double-layer corrugated metal roof B are arranged in parallel is the Y direction (see Figures 1(A), 11(A), etc.). Furthermore, the direction of the longitudinal direction of each corrugated metal roof panel 8 is defined as the X direction. Therefore, the longitudinal direction of the structural member 9 to which the roof support of this invention is attached is the Y direction (see Figures 1(A), 11(A), etc.). These X and Y directions also apply to the roof support A, and when incorporated into the double-layer corrugated metal roof B, it shall follow the X and Y directions of the double-layer corrugated metal roof B. The X direction may also be understood as the front-to-back direction. The X and Y directions are indicated in the figures.

[0029] The roof support A in the present invention mainly comprises a first clamping member A1, a second clamping member A2, a pivot member 51, and a fastening member 52 (see Figures 1, 2, 3, etc.), and is made of metal. The first clamping member A1 and the second clamping member A2 have substantially symmetrical and equivalent shapes in the Y direction (see Figures 1(B), 2(A), 3(A), 5(A), etc.). The first clamping member A1 has a first head portion 1 The first clamping member A2 has a second head 3 and a second leg 4 and It has a second head portion 3 facing upward, and a second leg portion 4 is formed to extend downward in an inclined manner from the second head portion 3 (see Figures 2 to 4).

[0030] The first head portion 1 of the first clamping member A1 has a vertical surface on one side in the width direction (Y direction) and an inclined surface on the other side. The housing has a roughly trapezoidal shape. The first head portion 1 has a flat top surface 11, a vertical side surface 12, an inclined side surface 13, and two front-to-back side walls 14, 14. The lower edge of the inclined surface 13 is formed as a first fitting edge 13a (see Figures 2 to 4). This first fitting edge 13a is the part that fits into the inner side of the bent portion 84 to be fitted into the folded roof plate material 8, which will be described later. The first fitting edge 13a is formed at a position adjacent to the outer end of the first head portion 1, where the outer end of the first head portion 1 refers to the outer end in the width direction (Y direction) of the first head portion 1 (see Figures 3(A), 4(A), etc.).

[0031] Similarly, the second head portion 3 of the second clamping member A2 is vertical on one side in the width direction and inclined on the other side. The housing has a roughly trapezoidal shape and has a flat top surface 31, a vertical side surface 32, an inclined side surface 33, and two front-to-back side walls 34, 34. The lower edge of the inclined surface 33 is formed as a second fitting edge 33a (see Figures 2 to 4). This second fitting edge 33a is formed at a position adjacent to the outer end of the second head 3, where the outer end of the second head 3 refers to the outer end in the width direction (Y direction) of the second head 3 (see Figures 3(A), 4(E), etc.).

[0032] The first leg portion 2 of the first clamping member A1 is composed of two leg plates 21, 21 of the same shape as a pair. The first leg portion 2 is constructed such that both leg plates 21, 21 are formed parallel and in a parallel state at both ends of the first head portion 1 in the front-rear direction (X direction) [see Figures 2, 3(B), 4, etc.]. Both leg plates 21, 21 of the first leg portion 2 have a first fastening portion 22 in the middle and a first fitting projection 23 at the lower end. In addition, the first fastening portion 22 has a recessed portion 22a that is recessed in a roughly semicircular (curved) shape above the protruding portion (see Figures 1 to 4, etc.). The recessed portion 22a is included in the first fitting projection 23 and serves to enclose half of the width direction (Y direction) of the fastening portion J of the lower folded plate roof B1 in the double-layer folded plate roof B described later [see Figure 1(B)].

[0033] Similarly, the second leg portion 4 of the second clamping member A2 consists of two leg plates 41, 41 of the same shape as a pair. The structure is configured such that both leg plates 41, 41 are formed parallel and in a parallel state at both ends of the second head portion 3 in the front-rear (X direction) direction. Both leg plates 41, 41 of the second leg portion 4 have a second locking portion 42 in the middle and a second fitting projection 43 at the lower end.

[0034] Furthermore, the upper portion of the second clamping section 42 encloses half of the widthwise clamping section J of the lower corrugated metal roof B1. A recessed portion 42a is formed in a roughly semicircular shape to allow for attachment (see Figures 1 to 4, etc.). This recessed portion 42a is part of the second fitting projection 43. The fastening portion J is the part formed by fastening the lower fastening portion 85 and the upper fastening portion 86 of adjacent corrugated roofing panels 8,8 together. In addition, in the double-layered corrugated roof B, where the hanger 87 is installed, the fastening portion J includes a part that contains the tongue piece 87b of the hanger 87.

[0035] The first clamping portion 22 of the first clamping member A1 and the second clamping portion 42 of the second clamping member A2 are positioned close to each other, thereby clamping the neck portion Jn of the clamping portion J of the lower corrugated roof B1 from both sides in the width direction. The roof support A is then fixed to the fastening portion J of the lower corrugated metal roof B1. The neck portion Jn is This is the constricted lower part of the clamping portion J, and this neck portion Jn is formed from the lower ridge portion 85 and the upper ridge portion 86. Furthermore, the upper part of the clamping portion J is enclosed by the recessed portion 22a of the first clamping member A1 and the recessed portion 42a of the second clamping member A2 [see Figure 1(B)].

[0036] The first clamping portion 22 of the first clamping member A1 faces inward towards both leg plates 21, 21 of the first leg portion 2. Formed in a protruding shape, the second clamping member A2's second leg portion 42 Both leg plates 41, 41 are formed in a protruding shape toward the inward side (see Figures 1 to 4, etc.). In other words, the first clamping portion 22 and the first fitting projection 23 of the first clamping member A1, and the second clamping portion 42 and the second fitting projection 43 of the second clamping member A2 are symmetrical and identical in shape (including substantially identical in shape) and are configured to face each other (see Figures 1 to 4, etc.).

[0037] The first head portion 1 and the first leg portion 2 of the first clamping member A1 are integrally formed from a metal plate. They are formed by pressing or bending (see Figures 2 and 4). Similarly, the second head portion 3 and the second leg portion 4 of the second clamping member A2 are formed by pressing or bending from a metal plate to form an integrated structure. It is formed by folding.

[0038] The first leg portion 2 (leg plate 21, 21) of the first clamping member A1 and the second leg portion 4 (leg) of the second clamping member A2 The plates 41, 41) are pivotally connected by crossing in an X-shape. More specifically, the first A pivot connection point is provided above the position of the first clamping portion 22 of the leg portion 2 (leg plates 21, 21) and the second clamping portion 42 of the second leg portion 4 (leg plates 41, 41), and this part is referred to as the pivot connection point P. The first clamping member A1 and the second clamping member A2 are pivotally connected so that they intersect in an X shape with the pivot connection point P as the center of intersection [see Figures 2, 3(A), and 5]. In other words, when the first head portion 1 and the second head portion 3 are separated from each other in the width direction (Y direction) by the pivot connection point P, the first clamping member A1 and the second clamping member A2 take on an approximately X shape (see Figures 1 to 4, etc.).

[0039] The first clamping member A1 and the second clamping member A2 are pivotally connected by a pivot member 51. The pivot member 51 is composed of a bolt 51a and a nut 51b, and a washer 51c is used as needed. Pivot holes 21a and 41a are formed at the pivot connection points P of both leg plates 21, 21 of the first leg 2 and both leg plates 41, 41 of the second leg 4, respectively. The threaded shaft of the bolt 51a of the pivot member 51 is inserted through these holes, and the first leg 2 (leg plates 21, 21) and the second leg 4 (leg plates 41, 41) are pivotally connected by the nut 51b (see Figures 2 and 3).

[0040] The distance between the two leg plates 21, 21 of the first leg 2 in the front-rear direction is set to be equal to the distance between the two leg plates 41, 41 of the second leg 4. At the pivot connection point P, the two leg plates 21, 21 and the two leg plates 41, 41 are pivotally connected so that they overlap alternately [see Figures 2, 3(B), (C), (D)] (see Figures 2, 3). In addition, although not specifically shown, the distances between the two leg plates 21, 21 of the first leg 2 and the two leg plates 41, 41 of the second leg 4 may be different, with one distance being narrower than the other.

[0041] In this case, the distance between the two leg plates 21, 21 of the first leg 2 is widened, and the distance between it and the two leg plates 41, 41 of the second leg 4 is narrowed, so that the two leg plates 41, 41 of the second leg 4 are fitted between the two leg plates 21, 21 of the first leg 2, thus providing a pivotal connection. Alternatively, the distance between the two leg plates 21, 21 of the first leg 2 may be widened, and the distance between it and the two leg plates 41, 41 of the second leg 4 may be narrowed, so that the two leg plates 21, 21 of the first leg 2 are fitted between the two leg plates 41, 41 of the second leg 4, thus providing a pivotal connection.

[0042] When the first clamping member A1 and the second clamping member A2 are pivotally connected as described above and the two first heads 1 and the second head 3 are in close proximity, the first head 1 is configured to be lower than the second head 3 (see Figures 1 to 3, etc.). Specifically, when the first head 1 and the second head 3 are in close proximity, there is a height difference H between their tops, and the top surface 11 of the first head 1 is set to be lower than the top surface 31 of the second head 3 (see Figures 3(A) and 5(A)). The height difference H is approximately equal to the height of the hanger base 87a of the hanger 87, which will be described later (see Figures 1(A) and 6(A)).

[0043] The top surface 11 of the first head 1, which is at a low position, is where the hanger base 87a of the hanger 87 (described later) will be installed and fixed, and a fixing hole 11a for the hanger is formed on the top surface 11 (see Figures 2, 3(B), 4(A), (C), (D), etc.). The fixing hole 11a for the hanger is the part through which the threaded shaft portion of the fixing bolt 53 for fixing the hanger 87 (described later) to the top surface 11 of the first head 1 is inserted. Specifically, the diameter of the fixing hole 11a for the hanger is preferably such that the threaded shaft portion of the fixing bolt 53 can be inserted loosely (with some leeway).

[0044] The first head 1 of the first clamping member A1 and the second head 3 of the second clamping member A2 are connected by a fastening member 52 so that they are close to each other. Specifically, a vertical plate-like portion extends downward from the lower end of the inner vertical side surface 12 of the first head 1, forming a first hanging piece 15, and a connecting hole 15a is formed in the first hanging piece 15 [see Figures 2(B), 3(C), 4, 5, etc.].

[0045] The connecting hole 15a is a through hole with a diameter larger than the threaded shaft of the bolt 52a of the fastening member 52. Similarly, a vertical plate-like portion extends downward from the lower end of the inner vertical side surface 32 of the second head 3, forming a second hanging piece 35, and a connecting hole 35a is formed in the second hanging piece 35. The connecting hole 35a is a through hole with a diameter larger than the threaded shaft of the bolt 52a of the fastening member 52.

[0046] Furthermore, it is preferable that both the connecting hole 15a of the first hanging piece 15 and the connecting hole 35a of the second hanging piece 35 be elongated holes that are elongated in the front-to-back direction (X direction) [see Figures 2(B), 4(B), and (F)]. By making both the connecting hole 15a and the connecting hole 35a elongated holes, when the first hanging piece 15 and the second hanging piece 35 are facing each other, the connecting hole 15a and the connecting hole 35a will always intersect in the front-to-back direction (X direction), and the threaded shaft portion of the bolt 52a can easily pass through the connecting hole 15a and the connecting hole 35a.

[0047] Then, the first hanging piece 15 of the first head 1 and the second hanging piece 35 of the second head 3 are connected to the first head 1 and the second head 3 via their respective connecting holes 15a and 35a and the bolts 52a and nuts 52b of the fastening member 52 (see Figures 3(A), (C), and 5). When the bolts 52a and nuts 52b of the fastening member 52 are tightened, the first head 1 and the second head 3 move closer together via the first hanging piece 15 and the second hanging piece 35, and the lower parts of the first leg portion 2 and the second leg portion 4 move closer together by rotation with the pivot connection point P as the pivot point, and the first choke locking portion 22 and the second choke locking portion 42 and the first fitting projection 23 and the first fitting projection 23 move closer together (see Figure 5).

[0048] Furthermore, a cube-shaped anti-rotation portion 52a' may be formed at the base of the bolt 52a of the fastening member 52 between the head and the screw shaft portion (see Figures 2(C) and 3(C)). With this configuration, the anti-rotation portion 52a' is inserted into the connecting hole 15a of the first hanging piece 15 together with the screw shaft portion of the bolt 52a, allowing for efficient tightening of the bolt 52a and nut 52b without them rotating together. A bolt having such an anti-rotation portion 52a' is sometimes called a square-root bolt. In addition, the fastening member 52 may be equipped with a washer 52c in addition to the bolt 52a and nut 52b. The washer 52c is preferably a spring washer.

[0049] In addition, the connecting hole 15a of the first hanging piece 15 may be configured to have an internal thread member that screws onto the bolt 52a of the fastening member 52, fixed by welding or the like [see Figure 4(D)]. Here, the internal thread member is a nut 52b. In other words, the nut 52b is fixed to the inside of the connecting hole 15a of the first hanging piece 15 by welding [see Figure 4(D)]. Furthermore, the second hanging piece 35 may have a connecting hole 35a with a diameter larger than the screw shaft diameter of the bolt 52a of the fastening member 52, and the fastening member 52 of the first hanging piece 15 may have an internal thread that screws onto the bolt 52a of the fastening member 52 [see Figure 4(C)]. In this case, the fastening member 52 consists only of the bolt 52a, and the nut 52b is not required.

[0050] Then, the first head 1 of the first clamping member A1 and the second head 3 of the second clamping member A2 come into close proximity to each other due to the tightening of the clamping member 52. At this time, a predetermined gap (clearance) S is provided between the vertical side surface 12 of the first head 1 and the vertical side surface 32 of the second head 3, as the distance between the first head 1 and the second head 3 as they come into close proximity and actually come into contact [Figures 3(A), 5(A)]. (See also) etc. The gap S is such that when the roof support A of the present invention is properly attached to the lower corrugated roof B1 of the double corrugated roof B, the first head 1 and the second head 3 are in close proximity. It is meant to give you some leeway.

[0051] This gap S allows the first head portion 1 and the second head portion 3 to move closer together and the distance between them to narrow due to external forces such as negative pressure from the outside wind, and the first leg portion 2 and the second leg portion 4 to move even closer together, and the first clamping portion 22 and the second clamping portion 42 and the first fitting projection 23 and the second fitting projection 43 to move even closer together. Here, the gap S may also be the gap that occurs between the vertical portion of the hanger 87 attached to the top surface 11 of the first head portion 1 and the vertical side surface 32 of the second head portion 3 of the second clamping member A2.

[0052] In a second embodiment of the roof support A of the present invention, the top surface 11 of the first head 1 of the first clamping member A1 and the top surface 31 of the second head 3 of the second clamping member A2 are configured to be at the same height in the vertical direction (see Figure 10). Specifically, in the second embodiment of the roof support A, when the first head 1 and the second head 3 are in close proximity, the tops of both are on the same plane or substantially on the same plane, and the two fitted bent portions 84, 84 of the mountain-shaped portion of the upper corrugated metal roof B2 are fitted to the first fitting edge 13a of the first head 1 and the second fitting edge 33a of the second head 3, respectively. In this embodiment, the hanger 87 is not required for the upper corrugated metal roof B2.

[0053] Here, the mountain-shaped sections of the lower corrugated metal roof B1 and the upper corrugated metal roof B2 refer to the lower corrugated metal roof B1 and The corrugated metal roof panels 8 that make up the upper corrugated metal roof B2 are adjacent to each other, and the lower edge portion 8 of one of the corrugated metal roof panels 8 This refers to the trapezoidal mountain-shaped portion formed by the two rising sections 82 and the two mountain-shaped peaks 83, 83 when the upper edge 86 of the other folded roof sheet material 8 is fastened together to form the fastened section J (see Figures 1 and 11).

[0054] Next, in the first embodiment of the roof support A of the present invention, the first clamping member A1 and the There are configurations in which the clamping member A2 is covered with resin or coated with resin. The portion of the first clamping member A1 that is covered with resin or coated with resin is referred to as the first resin-coated portion 61, and the portion of the second clamping member A2 that is covered with resin or coated with resin is referred to as the second resin-coated portion 62 (see Figure 9).

[0055] Specifically, the first resin coating portion 61 and the second resin coating portion 62 are connected to the first clamping member A1 and the second In a case where the clamping member A2 is properly mounted on a mountain-shaped section centered on the clamping portion J between adjacent corrugated roof panels 8,8,... that constitute the lower corrugated roof B1 of a two-layer corrugated roof B, the portion of the first clamping member A1 and the second clamping member A2 that is in direct contact with the corrugated roof panel 8 is covered with resin [see Figure 9(D)].

[0056] The first resin coating portion 61 and the second resin coating portion 62 are not provided on the entire first clamping member A1 and the second clamping member A2, but only on at least a portion of them, and this portion specifically refers to the contact (contact) points between the roof support A and the lower corrugated sheet roof B1 and the upper corrugated sheet roof B2, as described above. The first resin coating portion 6 provided on the first clamping member A1 The second resin coating portion 62 provided on the 1 and 2 clamping member A2 is on the upper part of the double-layer corrugated sheet roof B. It serves as insulation, blocking the flow of temperature from the layered corrugated metal roof B2 to the lower layered corrugated metal roof B1 [see Figures 4(A) and (B)].

[0057] Even if the outside temperature, such as low or high temperature, is transmitted from the upper corrugated sheet roof B2 of the double-layer corrugated sheet roof B to the roof support A, the first resin coating portion 61 and the second resin coating portion 62 will not transmit the outside temperature to the upper corrugated sheet roof B2 of the double-layer corrugated sheet roof B to the roof support A. From component A to the lower corrugated metal roof B1, heat transfer is almost completely blocked, preventing heat transfer, and below This system can maintain a nearly constant indoor temperature under the layered corrugated metal roof B1.

[0058] Furthermore, the provision of a first resin coating portion 61 and a second resin coating portion 62 on the roof support A helps to reduce the rattling phenomenon in the upper corrugated metal roof B2. As a result, the upper corrugated metal roof B2 is affected by the outside temperature, and especially in summer, it gets hotter. The corrugated metal roofing panels 8 that make up the layered corrugated metal roof B2 undergo thermal expansion and contraction along the longitudinal direction (X direction). In this case, a misalignment occurs between the upper corrugated metal roof B2 and the roof support A that supports the upper corrugated metal roof B2, generating vibration and noise. The first resin coating portion 61 and the second resin coating portion 62 play a role in minimizing the generation of vibration and noise caused by the misalignment with the upper corrugated metal roof B2, thereby suppressing the rattling phenomenon.

[0059] Here, the first resin-coated portion 61 and the second resin-coated portion 62 are made of fluidized polyethylene, and more specifically, the coating is performed by immersing a part of the first clamping member A1 and the second clamping member A2 in a container (or "tank") containing powdered resin paint, thereby forming the first resin-coated portion 61 and the second resin-coated portion 62. The first resin-coated portion 61 and the second clamping member A2 are provided in the parts of the first clamping member A1 and the second clamping member A2 that directly contact the lower corrugated roof B1 and the upper corrugated roof B2 of the two-layer corrugated roof B.

[0060] Specifically, in the first head section 1 and the second head section 3, multiple corrugated metal roofs make up the upper corrugated metal roof B2. In the base plate material 8,8,..., the mountain-shaped portion centered on the joint J between adjacent corrugated roof plate material 8,8 is properly supported from below by the roof support A, and the portion of the first head 1 and second head 3 that is in direct contact with the upper corrugated roof B2 is coated with resin. This refers to the part that is being treated [see Figures 1(A) and 9(B)].

[0061] More specifically, the first resin coating portion 61 is the inclined side surface 13 (first fitting edge 1) of the first head portion 1. The first resin coating portion 62 is applied to substantially the entire surface of the second head portion 3 (including the second fitting edge 33a), and to the outer parts of both side walls 14 and the top surface 11 (see Figure 9). The second resin coating portion 62 is applied to substantially the entire surface of the inclined side surface 33 (including the second fitting edge 33a) of the second head portion 3, and to the outer parts of both side walls 34 and the top surface 31 (see Figure 9). In the first leg portion 2, the first resin coating portion 61 is provided on the first locking portion 22 and its surrounding area, and on the first fitting projection 23 and its surrounding area (see Figure 9). The first locking portion 22 also includes a recessed portion 22a, and this recessed portion 22a may also be partially or entirely coated with resin.

[0062] Furthermore, in the second leg portion 4, the second resin coating portion 62 is provided on the second clamping portion 42 and its surrounding area, and on the second fitting projection 43 and its surrounding area (see Figure 9). The second clamping portion 42 also includes a recessed portion 42a, and this recessed portion 42a may also be partially or entirely coated with resin.

[0063] In the portion of the first clamping member A1 to which the first resin coating portion 61 is applied, the first fitting edge 13a Even if the first clamping portion 22 and the first fitting projection 23 are coated with resin on their surfaces, they may simply be referred to as the first fitting edge 13a, the first clamping portion 22, and the first fitting projection 23. Similarly, in the portion of the second clamping member A2 to which the second resin coating portion 62 is applied, the second fitting edge 33a, the second clamping portion 42, and the second fitting projection 43 may simply be referred to as the fitting edge 43a, the second clamping portion 42, and the second fitting projection 43, even if their surfaces are coated with resin.

[0064] The cross-sections of the portions of the first head 1 and first leg 2 to which the first resin coating 61 is applied are configured to completely surround the metal portion [see Figures 9(B) and (C)]. Similarly, the cross-sections of the portions of the second head 3 and second leg 4 to which the second resin coating 62 is applied are configured to completely surround the metal portion. In addition, the hanger 87 may also be coated with resin as needed.

[0065] Next, we will describe the double-layer corrugated metal roof B. First, we will describe the structure of the double-layer corrugated metal roof B. The double-layer corrugated metal roof B consists of a lower corrugated metal roof B1, in which multiple corrugated metal roof panels 8 are arranged side by side, each having a lower edge 85 on one side in the width direction and an upper edge 86 on the other side, with the lower edge 85 and upper edge 86 of adjacent corrugated metal roof panels 8, 8 being fastened together, and an upper corrugated metal roof B2 having the same structure as the lower corrugated metal roof B1, with the outer end being a first fitting edge 13a. A first clamping member A1 having a first head portion 1 and a first leg portion 2 that extends downward from the first head portion 1 in an inclined manner and has a first fastening portion 22 in the middle and a first fitting projection 23 at its lower end. The second clamping member A2, which has a second head portion 3 with a second fitting edge 33a at its outer end and a second leg portion 4 that extends downward from the second head portion 3 in an inclined manner and has a second locking portion 42 in the middle and a second fitting projection 43 at its lower end, is pivotally connected to the second clamping member A2 by crossing them in an X shape with the pivot member A2 51. Furthermore, the first head portion 1 is equipped with a roof support A positioned lower than the second head portion 3, and the opposing 82,8 of the two adjacent corrugated roof panels 8 in the lower corrugated roof B1 The roof support A is positioned on 2, and the first leg portion 2 and the second leg portion 4 of the roof support A engage the fastening portion J of the lower corrugated sheet roof B1 with both of the fitted bent portions 84, 84. In addition, a predetermined gap (clearance) s is provided between the opposing surfaces of the first head 1 and the second head 3, and the hanger 87 for the upper corrugated metal roof B2 is fixed to the first head 1, thereby providing the upper corrugated metal roof B2.

[0066] Furthermore, the details of the two-layer corrugated metal roof B will be explained. The two-layer corrugated metal roof B mainly consists of the lower corrugated metal roof B1, the upper corrugated metal roof B2, and the roof support A (see Figure 1). The lower corrugated metal roof is sometimes called the lower chord roof, and the upper corrugated metal roof is sometimes called the upper chord roof. The lower corrugated metal roof B1 and the upper corrugated metal roof B2 have the same or nearly the same configuration, and the lower corrugated metal roof B1 and the upper Each of the corrugated metal roofing panels 8 that make up the corrugated metal roof B2 are identical or nearly identical. The layered corrugated metal roof B1 and the upper layered corrugated metal roof B2 are constructed from the same type of corrugated metal roofing material 8.

[0067] The corrugated metal roofing panels 8 that make up the lower corrugated metal roof B1 and the upper corrugated metal roof B2 are the same, so they are assigned the same reference numeral. And, for the corrugated metal roofing panels 8 that make up the lower corrugated metal roof B1 The base plate material 8 and the corrugated roof plate material 8 that constitute the upper corrugated roof B2 are referred to as such. The structure of each corrugated roof plate material 8 that constitutes the lower corrugated roof B1 and the upper corrugated roof B2 is such that a flat main plate 81 is provided. As a result, raised portions 82, 82 are formed on both sides of the main plate 81 in the width direction, and mountain-shaped peaks 83, 83 are formed from the upper ends of the raised portions 82, 82. Then, the raised portions 82 and mountain-shaped peaks 83 on both sides in the width direction (Y direction) of the folded roof plate material 8 form a semi-mountain-shaped portion.

[0068] A lower ridge portion 85 is formed on one side of the corrugated roof sheet 8 in the width direction of the V-shaped peak 83, and an upper ridge portion 86 is formed on the other side of the V-shaped peak 83. The lower ridge portion 85 and the upper ridge portion 86 are formed in a rounded ridge shape, which has an arc-shaped portion in its cross-section, but there are also other types, such as a square ridge type with a roughly rectangular shape and an upright ridge type with a roughly inverted L-shape.

[0069] Furthermore, a V-shaped bottom portion 81a, with a roughly flattened V-shaped cross-section, is formed at the center of the main plate 81 in the width direction (Y direction) [see Figure 1(A)]. This V-shaped bottom portion 81a is the deepest part of the main plate 81 [see Figure 1(A)] and is formed continuously in the longitudinal direction (X direction) of the main plate 81.

[0070] Next, a fitted bent portion 84 is formed on each of the aforementioned rising portions 82. The fitted bent portion 84 is formed as a stepped portion at the midpoint in the height direction of both of the aforementioned rising portions 82, and is a portion of the rising portion 82 formed so that the upper side of the stepped portion protrudes outward more than the lower side [see Figures 1(B) and 7]. In other words, it is a portion of the rising portion 82 formed so that the lower side of the stepped portion protrudes inward more than the upper side. The fitted bent portion 84 in the corrugated roofing sheet 8 is a portion that serves to fit with the first fitted edge 13a of the first head 1 and the second fitted edge 33a of the second head 3 of the roofing support A [see Figure 1(B)].

[0071] Next, in the two-layer corrugated metal roof B, a roof support A is installed on the lower corrugated metal roof B1, The process of installing the upper corrugated metal roof B2 on roof support A will be explained with reference to Figures 7 and 8. Here, in Figures 7 and 8, the lower corrugated metal roof B1 is assumed to be in a state where construction has already been completed. Next, we will describe the lower corrugated metal roof B1. The lower corrugated metal roof B1 is composed of corrugated metal roofing material 8, a tight frame 71, and structural material 9 to form the roof (including wall-like sections). The tight frame 71 that supports the lower corrugated metal roof B1 has a fitting mounting member 72 for the roof support A.

[0072] Multiple tight frames 71, 71, ... are arranged on the structural member 9 that supports the lower corrugated metal roof B1. And the multiple corrugated roof panels 8, 8, ... that make up the lower corrugated roof B1 are the lower edge 8 5 and the upper section 86 are fastened together, and the opposing fitted bent sections 84, 84 of the adjacent corrugated roof panels 8, 8 are fitted together by the fitting mounting member 72 of the tight frame 71, thereby fixing the corrugated roof panel 8 to the tight frame 71.

[0073] The lower corrugated roof B1 consists of multiple corrugated roof panels 8,8,... with lower and upper sections 85 and 86. Roof support A is installed on the mountain-shaped section centered on the connection point. Roof support A is installed in the Y direction of the multiple parallel folded roof panels 8,8,... that make up the lower folded roof B1. They are also installed in a matrix configuration at predetermined intervals along the X direction.

[0074] The installation of the roof support A to the lower corrugated metal roof B1 involves fastening the first head 1 and the second head 3 together. The bolt 52 is loosened and separated from each other. As a result, the first leg portion 2 and the second leg portion 4 open up and separate from each other, and the first clamping portion 22 and the second clamping portion 42 and the first fitting projection 23 and the second fitting projection 43 open up and separate from each other [see Figure 7(A)]. Then, the fastening member 52, consisting of a bolt 52a and a nut 52b, is tightened to narrow the gap between the first leg portion 2 and the second leg portion 4, locking the neck portion Jn of the clamping portion J in a clamping state, and the upper portion of the clamping portion J is enclosed by the recessed portion 22a and the recessed portion 42a.

[0075] Furthermore, as the first clamping portion 22 and the second clamping portion 42 come into proximity, the first clamping member A1 is fitted. The joint projection 23 and the second fitting projection 43 of the second clamping member A2 are in close proximity, and adjacent to the lower corrugated roof B1. The roof support A is fitted in a clamped state to the two fitted bent portions 84, 84 of the mountain-shaped section made up of the adjacent corrugated roofing panels 8, 8, and is installed and fixed on the mountain-shaped section of the lower corrugated roof B1. See Figures 7(B) and 7(C).

[0076] Next, the corrugated roof sheet material 8 constituting the upper corrugated roof B2 is placed between adjacent roof support members A, A in a plurality of roof support members A installed and fixed on the lower corrugated roof B1, and the first fitting end edge 13a of the first head 1 of the first clamping member A1 and the second So that the second fitting edge 33a of the second head 3 of the clamping member A2 can be properly fitted. It will be set.

[0077] Then, the hanger 87 is installed on the top surface 11 of the first head 1 of the roof support A [see Figure 8(D)], and the corrugated roof sheet 8 is placed between adjacent roof support A, A on the lower corrugated roof B1. The corrugated roofing material 8 is pressed in, and its two fitted bent portions 84, 84, the first fitted end edge 13a of the opposing first clamping member A1 of the adjacent roof support A, A, and the second clamping member The second fitting edge 33a of A2 is fitted together [see Figure 8(E)].

[0078] Then, the lower edge portion 85 of the corrugated roof sheet 8 that constitutes the upper corrugated roof B2 is attached to the tongue of the hanger 87. The hanger 8 is fastened to 87b and attached to the top surface 11 of the first leg portion 2 of the first clamping member A1 of the roof support A. The hanger base 87a of 7 is fixed with fixing bolts 53 and internal threaded members (nuts, etc.) 54. Mounting holes 87c are formed in the hanger base portion 87a, and the fixing bolts 53 are inserted through these mounting holes 87c. Next, the lower and upper edges 85 and 86 of adjacent corrugated roof panels 8,8 are fastened together to construct the upper corrugated roof B2 of the two-layer corrugated roof B [see Figures 1 and 8(F)].

[0079] As described above, the hanger 87 comprises a hanger base portion 87a and a tongue piece 87b as its basic configuration. The hanger base portion 87a is roughly rectangular in shape when viewed from above, with an inverted gate shape in cross-section. The tongue piece 87 has a roughly "?" shape in cross-section perpendicular to its longitudinal direction, and the hanger base portion 87a is formed in an inverted gate shape with the top open in its longitudinal direction [see Figure 2(D)]. The hanger base portion 87a has a fixing through hole 87c through which a fixing bolt 53 passes. The hanger base portion 87a is placed on the top surface 11 of the first head portion 1, and the hanger base portion 87a is fixed by the fixing bolt 53 and an internal thread member 54 (nut, etc.).

[0080] Furthermore, the lower and upper edges 85 and 86 of adjacent corrugated roofing panels 8,8 are fastened together by sandwiching the tongue piece 87b of the hanger 87. There is also an embodiment in which the hanger 87 consists only of the tongue piece 87b and fixing bolts 53. Other shapes of the hanger 87 include a housing-like structure with the upper part of the hanger base 87a open, or a washer-like structure with a predetermined rectangular plate thickness.

[0081] In this way, the clamping-type corrugated roofing sheet 8 is fixedly supported on the top surface 11 of the first clamping member A1 of the roof support A of the present invention via the hanger 87, and both first fittings of the roof support A The corrugated roofing material that constitutes the upper corrugated roof B2 is formed by the fitting edge 13a and the second fitting edge 33a. The fitted bent portions 84, 84 of 8 are fixed in place. As a result, the roof support A of the present invention can very firmly support and fix an exterior structure such as a roof or wall constructed with corrugated roofing materials 8, 8, ... and can exhibit particularly excellent durability against negative pressure caused by strong winds.

[0082] In the present invention, the roof support A is used for a two-layer corrugated metal roof B, specifically for the lower corrugated metal roof B1 and the upper corrugated metal roof. By locking and fitting each of the fastening portions J and the fitted bent portions 84 of the plate roof B2, An extremely strong double-layer corrugated metal roof can be constructed. Furthermore, when a large negative pressure Q is applied to the upper corrugated metal roof B2 during strong winds such as typhoons, and an external force due to the negative pressure Q is applied that lifts the upper corrugated metal roof B2 upward, the mountain shape of the upper corrugated metal roof B2 The two fitted bent portions 84 of the part attempt to lift the first fitted edge 13a of the first head 1 and the second fitted edge 33a of the second head 3 of the roof support A upward [see Figure 6(B)].

[0083] At this time, the first head 1 and the second head 3 of the roof support rotate around the pivot connection point P so as to move closer to each other. Simultaneously, the first leg 2 and the second leg 4 rotate around the pivot connection point P so as to move closer to each other, and the first locking part 22 and the second locking part 42 and the first fitting projection 23 and the second fitting projection 43 move closer to each other, and are firmly locked and fitted by the locking part J and both fitted bent parts 84, 84 of the mountain-shaped part of the lower corrugated sheet roof B1, making it possible to withstand strong winds [see Figure 6(B)].

[0084] A two-layer corrugated metal roof B can be further modified to create a three-layer corrugated metal roof by adding another corrugated metal roof (see Figure 11). In this case, the top layer, the uppermost corrugated metal roof B3, is installed on top of the upper corrugated metal roof B2, resulting in a three-layer corrugated metal roof. Roof support members A are installed between the lower corrugated metal roof B1 and the upper corrugated metal roof B2, and between the upper corrugated metal roof B2 and the topmost corrugated metal roof B3. Furthermore, the positions of the fastening parts of the lower corrugated metal roof B1, the upper corrugated metal roof B2, and the topmost corrugated metal roof B3 all coincide (including approximate coincidence), and at support points where the fastening parts are aligned at the top, middle, and bottom, two roof support members A are used, one above the other.
