Description

The present invention relates to an eaves door that can be easily and quickly attached to the eaves of a folded-plate roof that is made by connecting adjacent folded-plate roof panels via a fitting cap material, and to the folded-plate roof.

Traditionally, folded-plate roofs have been constructed using metal interlocking folded-plate roofing materials, with adjacent folded-plate roofing materials connected via interlocking cap materials, resulting in a series of trapezoidal gables at equal intervals. Various types of door panels have been developed that are attached to the eaves of the gabled areas of such roofs for purposes such as rainproofing and appearance improvement. Such door panels are called roof door panels or are also called decorative door panels or by other names.

In a typical example, the door is formed with an arm-like or plate-like protruding piece for insertion, and this protruding piece is used to attach to a part of the folded roof panel material using a fastener such as a screw. There are also types in which the drip edge provided below the door is attached to the exterior wall of the roof or to the structural material of the exterior wall using a fastener such as a screw. This type of door is discussed in Patent Document 1 and Patent Document 2 below.

JP 2019-120101 A Utility Model Registration No. 3209118

In Patent Document 1 (JP Patent Publication No. 2019-120101), the protruding claws, edges and tops on both sides of the eaves panel door are bent and fixed to the legs of the tight frame. In Patent Document 2 (Utility Model Registration No. 3209118), the drip edge provided below the panel door is attached to the exterior wall of the roof or to the structural material of the exterior wall with fasteners such as screws, and the folded plate roof panel panel door is attached to the eaves of the folded plate roof.

In Patent Document 1, the claws, edges and protruding parts on both sides of the eaves door must be bent and then wrapped around the tight frame to secure it in place. This requires tools to bend the claws, edges and protruding parts, and there are multiple bending points. As a result, installing one door takes a great deal of time and effort, placing a heavy physical burden on the worker and making it far from an efficient process.

In Patent Document 2 (Utility Model Registration No. 3209118), the water-repellent shape of the folding roof panel door is fixed to the exterior wall or the structural material of the exterior wall with tapping screws or the like, and the folding roof panel panel door is attached to the eaves of the folding roof. Therefore, the closing part of the panel door itself is simply placed on the eaves part of the folding roof and does not have any special fixing means. Therefore, not only is the installation work troublesome, but the panel door does not have sufficient strength to be attached to the eaves of the folding roof, and there are problems such as an unstable state even after installation. Therefore, the object of the present invention is to provide an eaves panel door and a folding roof thereof that solves the above problems and allows the eaves panel door to be easily and quickly attached to the eaves of a fitting type folding roof, especially one that uses a fitting cap material, and can be firmly attached.

Therefore, the inventors have conducted intensive research to solve the above-mentioned problems, and as a result, the invention of claim 1 is a eaves door to be attached to the eaves of a folded-plate roof, which is composed of a folded-plate roof material having rising sides formed on both sides in the width direction of the main plate and a fitting bent portion formed at the upper end of both rising sides, and a fitting cap material that fits into both the fitting bent portions of both adjacent folded-plate roof materials to connect both adjacent folded-plate roof materials, and which is a fitting cap material that is attached to the eaves of a folded-plate roof material and which is composed of a fitting cap material that fits into both the fitting bent portions of both adjacent folded-plate roof materials, and which is attached to the eaves of a folded-plate roof material and a fitting cap material that fits into both the fitting bent portions of both adjacent folded-plate roof materials and which connects ... The problem was solved by providing an eaves door that is characterized by having an upper part, a closing plate that is provided on the connection upper part and is parallel to the main door panel and is inserted between the two fitted bent parts, and a connection port part that has an insertion opening provided on the connection upper part and a protruding piece that protrudes from the inner periphery of the insertion opening toward the center, and the connection port part of the connection upper part is inserted into the screw shaft part of a mounting screw that is pre-installed between the opposing fitted bent parts of the adjacent folded roof panel materials at the eaves of the folded roof.

The above problem is solved by the invention of claim 2, which is an eaves door as described in claim 1, characterized in that the upper connection part is located on the front side of the main panel and is provided on the top of the main panel.The above problem is solved by the invention of claim 3, which is an eaves door as described in claim 1, characterized in that the upper connection part is located on the back side of the main panel and is provided on the top of the main panel.

The above problem was solved by the invention of claim 4, which is an eaves door as described in claim 1 or 2, characterized in that the number of protruding pieces is 3 or 4, each protruding piece is trapezoidal, is arranged at equal intervals around the periphery of the connection port, and has a tip that is inclined downward.

The invention of claim 5 is a eaves door having a main panel, a connection upper part provided at the top of the main panel and perpendicular to the main panel, a closing plate provided at the connection upper part, parallel to the main panel, and inserted between the two bent parts to be fitted, an insertion opening provided at the connection upper part and a protruding piece protruding from the inner periphery of the insertion opening toward the center, a folded roof panel material having rising sides formed from both sides in the width direction of the main panel and bent parts to be fitted at the upper ends of both rising sides, and a folded roof panel material having a bent part to be fitted to each other, the bent parts to be fitted to each other of the adjacent folded roof panel materials, The above problem was solved by providing a folded-plate roof that is composed of a fitting cap material that connects the adjacent folded-plate roof panels together, and a mounting screw having a fixed base portion that is arranged and fixed between the fitted bent portions of the adjacent folded-plate roof panels and a screw shaft portion provided at the bottom of the fixed base portion, the mounting screw being attached to both the fitted bent portions of the folded-plate roof panels, the screw shaft portion of the mounting screw being inserted into the connection port of the eaves door, and the protruding piece being bitten into the screw shaft.

The invention of claim 6 is a folded plate roof as described in claim 5, characterized in that the fixed base part of the mounting screw is provided with a spacer piece arranged between the upper surface of the fitted bent part and the fitting cap material, thereby solving the above problem. The invention of claim 7 is a folded plate roof as described in claim 5, characterized in that the spacer piece is bent and folded back from both ends in the width direction above the fixed base part, thereby solving the above problem. The invention of claim 8 is a folded plate roof as described in claim 5, characterized in that the spacer piece is a separate member from the fixed base part and fixed to the upper part of the fixed base, thereby solving the above problem.

The invention of claim 9 solves the above problem by providing a folded plate roof as described in claim 5 or 6, in which the number of protruding pieces is 3 or 4, each protruding piece is trapezoidal, and is arranged at equal intervals around the periphery of the connection port, with the tip portion formed with an inclination that slopes downward.

In the invention of claim 1, the eaves door can be attached to the eaves of the folded-plate roof by fitting adjacent interlocking-type folded-plate roof panels together with the interlocking cap material, and the worker simply aligns the connection port of the eaves door in this invention with the tip of the screw shank of the mounting screw that is pre-installed on the folded-plate roof. The screw shank then passes through the connection port of the eaves door, and by continuing to push the eaves door upward, the screw shank penetrates and penetrates the insertion opening of the connection port, and the protruding piece of the connection port bites into the screw groove (thread valley) of the screw shank, making it possible to attach the eaves door to the eaves of the folded-plate roof very easily and quickly.

Furthermore, the protruding piece of the connection port bites into the thread groove (thread root) of the screw shaft, allowing the eaves door to be extremely firmly fixed to the screw shaft together with the connection port. In particular, once the protruding piece of the connection port bites into the thread groove (thread root) of the screw shaft, its free end basically tilts and deforms downward, making it easier for workers to push up the eaves door even further.

When the eaves door is subjected to a downward load in a direction that causes it to come off the screw shaft, the protruding piece acts as a barb or barb and tries to bite deeper into the screw groove (thread root), making the eaves door even more firmly attached to the eaves of the folded-plate roof and providing excellent durability against downward loads.

In particular, in the present invention, a blocking plate is formed at the upper part of the connection, parallel to the main panel of the panel. In addition, a relatively small gap is created between the two fitted bent parts of adjacent folded roof panels in a fitting type folded roof that uses the eaves panel of the present invention, and if left as is, wind will flow in. Therefore, when the eaves panel of the present invention is attached to a fitting type folded roof, the blocking plate is inserted between the two fitted bent parts. This allows the blocking plate to block the gap, further reducing the gap area between the eaves of the folded roof and the eaves panel, improving the appearance and preventing the intrusion of wind, rain, dust, etc.

The invention of claim 2 is configured so that the upper connection part is located on the front side of the main panel of the panel, making it easy to confirm the positions of both the tip of the screw shaft part and the connection port part of the eaves panel, and the screw shaft part can be inserted into the connection port part, improving the efficiency of the installation work of the eaves panel door to the eaves. In the invention of claim 3, the upper connection part is configured so that it is located on the back side of the main panel of the panel, so that when the eaves panel door is installed to the eaves of the folded plate roof, the screw shaft part is hidden from the outside by the eaves panel door, making it a suitable structure when it is preferred to make the screw shaft part inconspicuous.

The invention of claim 4 has three or four protruding pieces, each of which is trapezoidal in shape and arranged at equal intervals around the connection port with the tip slanted downward, making it possible to more easily and securely attach the eaves door to the eaves of a folded-plate roof. When the number of protruding pieces is three, the three protruding pieces bite into the screw shaft from three sides, creating a stable bite-in state. When the number of protruding pieces is four, the four protruding pieces bite into the screw shaft from all four sides, making it even more stable and strong.

Furthermore, the tip of the protruding piece is formed to be inclined downward, so that when the eaves door is attached to the eaves of the folded plate roof, the screw shaft can be easily inserted into the insertion opening of the connection port, and the eaves door can be attached to the eaves with little force. Furthermore, the tip of the protruding piece is inclined downward and bites into the screw shaft inserted from above the connection port, so when a load is applied downward to the eaves door, the protruding piece tries to bite even more strongly into the screw shaft, resulting in a durable attachment state. In the invention of claim 5, the eaves door of the present invention is attached to the eaves of a fitting type folded plate roof. Therefore, the eaves door can be easily and quickly attached to the eaves of a fitting type folded plate roof, resulting in a folded plate roof that is excellent in workability and work efficiency and reduces the burden on workers, and the eaves door can be attached extremely firmly.

In the inventions of claims 6 to 8, the fixing base portion of the mounting screw is provided with a spacer piece that is placed between the top surface of the fitted bent portion and the fitting cap material, so that the mounting screw installed on the top pieces of both fitted bent portions of adjacent folded roof panel materials is fixed between both fitted bent portions and the fitting cap material by the spacer piece. Therefore, when the eaves door is pushed up from below onto the eaves of the folded roof, the mounting screw does not rattle between the both fitted bent portions and the fitting cap material, and the eaves door can be attached to the eaves very easily.

In the invention of claim 9, the number of protruding pieces is three or four, each of which is trapezoidal and arranged at equal intervals around the periphery of the connection port, and the tips of the folded plate roof are formed with an inclination that slopes downward, allowing the eaves door to be attached very firmly to the eaves.

Below, an embodiment of the eaves door and its folded plate roof of the present invention will be described based on the drawings. Also, the eaves door A of the present invention may be called "eaves trim door" or "eaves water drain door" depending on the structure, but in the present invention, it will be mainly described as the eaves door. Furthermore, in the present invention, the component to which the eaves door A is attached is the folded plate roof B, and the eaves door A is attached to the folded plate roof B with mounting screws 3. First, the eaves door A will be described. The eaves door A of the present invention mainly has a door section 1 and a connection port section 2 (see Figures 1 and 2).

Furthermore, the panel door section 1 has a panel door main panel 11, a connecting upper part 12, an inclined side section 13, and a closing plate 15. Also, the eaves panel door A may have a trim section 14 as necessary (see Figures 1(A), 2(A), (B), etc.). Note that the "trim" in the trim section 14 is sometimes called a "water drain", and therefore the "trim section 14" is sometimes called a "water drain section 14". Also, the inclined side section 13 and the trim section 14 are provided as necessary, and may not be provided if they are not necessary.

The main panel 11 of the panel 11 is shaped to fit into the angled portion J of the folded-plate roof B to which the eaves panel A is attached, as viewed from the front. Specifically, the eaves panel A is formed into a shape that follows the approximate trapezoidal angled portion by connecting adjacent folded-plate roof panel materials 8, 8, ... when viewed from the front, via fitting cap materials 7, and is approximately the same shape as the eaves of the folded-plate roof B (see Figures 3, 4, 5, etc.).

A connection upper part 12 is formed at the top of the main panel 11 (see Figures 1 and 2). From the top edge and inclined edge on both sides of the width of the main panel 11, inclined sides 13, 13 are formed at approximately right angles to the main panel 11 and toward the back side. The blocking plate 15 is provided perpendicular or approximately perpendicular to the connection upper part 12 (see Figures 1(A) and 2(C)). Specifically, the blocking plate 15 is formed perpendicular to the tip part on the opposite side to the part of the connection upper part 12 that protrudes from the top of the main panel 11, and is bent so as to be integral with the connection upper part 12.

The blocking plate 15 serves to block the gap between the opposing fitted bent portions 83, 83 of adjacent folded roof panel materials 8, 8 of the folded roof B to which the eaves door A is to be attached (see Figures 3(A) and (B)). Therefore, the blocking plate 15 has a shape and size that fits into the gap between the fitted bent portions 83, 83, and is preferably approximately rectangular or square in shape (see Figures 3(B) and 4(B)). The blocking plate 15 serves to improve the appearance by reducing the gap area between the eaves of the folded roof B and the eaves door A, and to prevent the intrusion of wind, rain, dust, etc.

When the upper connection portion 12 and both inclined side portions 13, 13 are attached to the eaves of the folded-plate roof B, they come into contact with or are close to the underside of the folded-plate roof material 8 (see Figures 3(A) and (B)). In addition, a sealing material 4 may be attached to the inclined side portions 13, 13 and the upper connection portion 12 (see Figure 8). The sealing material 4 is string- or band-shaped and is made of sponge, rubber, urethane material, etc.

The sealing material 4 is continuously attached over both inclined side portions 13, 13 and the upper connection portion 12 with double-sided tape or adhesive, etc. (See FIG. 8(C)). In this way, by attaching the eaves door A to the eaves of the folded-plate roof B, the sealing material 4 is sandwiched between the eaves door A and the underside of the angled portion J of the folded-plate roof B, and a waterproof structure can be created between the folded-plate roof B and the eaves door A.

The main panel 11 may have a trapezoidal concave portion 11a formed on the back side that is approximately equal to the outer shape of the main panel, but slightly smaller (see Figures 1(A), 2(A), and (C)). The concave portion 11a provides reinforcement and improves the appearance. Furthermore, a parting portion 14 that is approximately rectangular when viewed from the front is formed at the lower end of the main panel 11 (see Figures 1(A), 2(A), and (C), etc.). The parting portion 14 is formed as necessary, but is not always formed.

The upper connection portion 12 can be formed integrally with the main panel 11 from a single metal plate. In this case, the upper connection portion 12 is bent from the top of the main panel 11 at a substantially right angle to the main panel 11, and the main panel 11 and the upper connection portion 12 are integrally press-formed. The upper connection portion 12 is formed so as to protrude forward from the front side of the main panel 11 (see Figures 1 and 2).

The upper connection portion 12 may be formed to protrude rearward from the back side of the main panel 11 (see Figure 6). Although not specifically shown, the upper connection portion 12 and the main panel 11 may be separate members that are fixed to the upper end of the main panel 11 by welding or other fixing means. A connection port 2 is formed at the approximate center of the upper connection portion 12 (see Figures 1 and 2). The connection port 2 is a portion that serves to attach the eaves end panel A to the eaves of the folded-plate roof B via a mounting screw 3 (described later) that is attached in advance to the eaves of the folded-plate roof B.

The connection port 2 has an insertion opening 21 and a protruding piece 22 that protrudes from the inner circumference of the insertion opening 21 toward the center (see Figures 1, 2(D), (E), and (F)). The connection port 2 is formed integrally with the connection upper part 12 of the panel door part 1. As a result, the connection upper part 12 together with the connection port 2 installs the eaves panel door A to the eaves of the folded plate roof B via the mounting screw 3 (see Figures 3 to 5). As described above, the connection port 2 is composed of the insertion opening 21 and the protruding piece 22.

The insertion opening 21 is a through-hole formed in the upper connection portion 12 through which the screw shaft portion 32 of the mounting screw 3 is inserted. A protruding piece 22 is formed that protrudes from the inner circumference of the insertion opening 21 toward the center position of the insertion opening 21. The screw shaft portion 32 of the mounting screw 3, which will be described later, is relatively inserted into the connection port portion 2 (see Figures 3(B) and (C) and Figure 5).

The protruding pieces 22 of the connection port 2 of the eaves door A are two or more, and are provided at equal intervals around the insertion opening 21 in the circumferential direction. The number of protruding pieces 22 of the connection port 2 may be one. Specifically, the number of protruding pieces 22 is preferably four. When the number of protruding pieces 22 is four, the four protruding pieces 22 will be equally spaced along the circumferential direction of the screw shaft portion 32 of the mounting screw 3 inserted through the insertion opening 21 and will bite into the screw groove portion (thread root portion) 32a of the screw shaft portion 32 at equal intervals, and the connection upper portion 12 of the face door portion 1 will be fixed to the mounting screw 3 in an extremely stable state [see (II) in Figure 3 (C) and Figures 5 (B) to (D)].

The protruding pieces 22 are preferably trapezoidal in shape, narrowing from the inner circumference of the insertion opening 21 toward the center (see Figs. 1B, 1C, 2C to 2D). There is a space between adjacent protruding pieces 22, but this space is part of the insertion opening 21 (see Fig. 1C). In addition, when the upper connection portion 12 is positioned horizontally, the tip of the protruding piece 22 of the connection port portion 2, that is, the part closer to the center of the insertion opening 21, is inclined downward. By inclining the tip of the protruding piece 22 downward, it becomes easier to insert the screw shaft portion 32 of the immobile mounting screw 3 from the upper side of the insertion opening 21 (see Figs. 5B to 5D).

It is also preferable to have three equally spaced protruding pieces 22 on the connection port 2, so that the protruding pieces 22 bite into the screw shaft 32 of the mounting screw 3 inserted into the insertion opening 21 from three directions at equal intervals, and the connection port 2 can be stably fixed (see Figures 7 (A) and (B)). The number of protruding pieces 22 on the connection port 2 can be five or more, so that the protruding pieces 22 bite into the screw shaft 32 of the mounting screw 3 from multiple directions at equal intervals, and the eaves door A can be firmly fixed (see Figures 7 (C) to (E)). In addition, the resistance from the protruding pieces 22 when the screw shaft 32 is inserted into the insertion opening 21 can be reduced, making it easier to attach the eaves door A to the folded-plate roof.

Next, the folded plate roof B to which the eaves door A of the present invention is attached will be described based on the process of attaching the eaves door A to the eaves of the folded plate roof B. The folded plate roof B is a fitting type folded plate roof using fitting cap material, and is mainly composed of a folded plate roof material 8 and a fitting cap material 7. The folded plate roof material 8 has an inclined rising side portion 82 formed at both ends in the width direction of the main plate 81, and fitting bent portions 83, 83 are formed from the upper ends of both the inclined rising side portions 82, 82 [see Figure 10 (A)]. The inclined rising side portion 82 is formed to be inclined upward and outward from both ends in the width direction relative to the main plate 81.

The fitted bent portion 83 is formed in a generally U-shaped cross section, with a horizontal piece 83a formed outward from the upper end of the inclined rising side portion 82, a vertical piece 83b formed from the outer end of the horizontal piece 83a, a top piece 83c formed inward from the upper end of the vertical piece 83b (towards the main plate 81), and a fitted bent piece 83d formed from the edge of the top piece 83c (see Figure 1 (B)).

The fitting cap material 7 is formed as a long object in its longitudinal direction (see Figures 3(A) to (C), 4, and 10), and consists of an upper surface portion 71 and fitting legs 72, 72. Specifically, the longitudinal length of the fitting cap material 7 is often approximately equal to the longitudinal length of the folded roof panel material 8. The fitting legs 72, 72 are formed downward from both sides of the width of the upper surface portion 71 (see Figures 3(B) and 4(B)).

The upper surface portion 71 is formed in a flattened triangular shape. The fitting leg portion 72 is composed of a side piece 72a, a fitting bent piece 72b, and a lower end bent piece 72c. The fitting bent pieces 72b, 72b are formed to bulge out and protrude toward the inside of the fitting cap material 7 so that they face each other.

Then, a bracket is fixed onto a structural member such as a purlin or beam, and a fitting retainer 85 is attached onto the bracket with fasteners such as bolts and nuts. The fitting retainer 85 has tongue pieces 85b, 85b formed on both sides of the retainer body 85a in the width direction (see FIG. 10(B)). Both tongue pieces 85b, 85b of the fitting retainer 85 are wrapped around the opposing fitted bent portions 83, 83 of the adjacent folded roof panel materials 8, 8 (see FIG. 10(B)).

As a result, the adjacent folded roof panel materials 8, 8 are fixed onto the structural material together with both fitted bent portions 83, 83. The fitting legs 72, 72 of the fitting cap material 7 are fitted into the fitted bent portions 83, 83 of the adjacent folded roof panel materials 8, 8, and by repeating this process in sequence, a folded roof B is constructed in which the approximately trapezoidal mountain-shaped portions J formed by the opposing inclined rising side portions 82, 82 of the adjacent folded roof panel materials 8, 8 and the fitting cap material 7 are connected at a predetermined interval.

The reference numeral 86 denotes an intermediate washer, which is composed of a washer housing portion 86a and a pressing piece 86b, and a through hole is formed in the bottom surface of the washer housing portion 86a through which the retaining clip mounting bolt 96 is inserted (see FIG. 10(B)). The intermediate washer 86 is housed in the retaining clip body 85 of the fitting retaining clip 85. The pressing pieces 86b are structured to press the tongue pieces 85b, 85b of the fitting retaining clip 85 (see FIG. 1, FIG. 2(A) and (B), FIG. 10(B)).

The mounting screw 3 is composed of an installation part 31, a screw shaft part 32, and a spacer 33, and the installation part 31 has a base plate 31a and a spacing plate 31b (see Figs. 3(B), (C), 4(B), 9, etc.). The installation part 31 is attached in a bridging manner to the tops (top pieces 83c, 83c) of both fitted bent parts 83, 83 of adjacent folded roof panel materials 8, 8 of the folded roof B (see Figs. 3(C) and 4(B)). The installation part 31 is in the shape of a plate, and its width is long enough to be installed on the top pieces 83c, 83c of both opposed fitted bent parts 83, 83 of adjacent folded roof panel materials 8, 8 of the folded roof B (see Fig. 3(C)).

Spacers 33 are provided on the installation section 31 and on both widthwise ends of the installation section 31. The spacers 33 fill the gap between the top pieces 83c, 83c of the fitted bent parts 83, 83 of the adjacent folded roof panel materials 8, 8 and the fitting cap material 7, so that the installation section 31 is fixed on the fitted bent parts 83, 83. The spacers 33 are formed as bent pieces 33a that are folded upward on both sides in the widthwise direction of the installation section 31 and have a cross section that is approximately flattened C-shaped and inverted flattened C-shaped [see Figures 3(C), 4(B), 9(A), and (B)]. The bent pieces 33a are folded upward from both sides in the widthwise direction of the installation section 31, so that the installation section 31 and the bent pieces 33a can be formed as one unit.

The installation section 31 and the bent piece 33a are made of thin metal plate, which allows the bent piece 33a to have elasticity. As a result, when the mounting screw 3 is installed between the two fitted bent parts 83, 83 of the folded-plate roof B and the fitting cap material 7, the bent piece 33a abuts against the back side of the fitting cap material 7, and the elasticity of the bent piece 33a fixes the installation section 31 onto the top pieces 83c, 83c of the two fitted bent parts 83, 83. In this way, the mounting screw 3 is securely fixed, which makes it easier to attach the eaves door A, which will be described later, to the eaves of the folded-plate roof B.

In another embodiment of the spacer 33 of the mounting screw 3, the spacer 33 is a separate member from the installation portion 31, and square-sectioned blocks 33b, 33b are fixed to both sides of the installation portion 31 in the width direction by welding or adhesive. The blocks 33b, 33b fill the gap between the top pieces 83c, 83c of the two fitted bent portions 83, 83 of the adjacent folded roof panel materials 8, 8 and the fitting cap material 7 to fix the installation portion 31 (see Figures 9(C) and (D)). The blocks 33b, 33b may be made of elastic materials such as rubber and synthetic resins, in addition to metal materials.

The installation section 31 has a spacing plate 31b formed below the base plate 31a (see Figs. 3(C), 4(B), and 9). The spacing plate 31b is formed downward at the middle of the width of the base plate 31a so that its cross section perpendicular to the width direction is roughly L-shaped, and is shaped to fit between the vertical pieces 83b, 83b of the adjacent fitted bent sections 83, 83 (see Fig. 3(C)).

When the mounting screw 3 is attached to the eaves of the folded-plate roof B, the screw shaft 32 is positioned so that it protrudes vertically downward between the fitted bent portions 83, 83 of the adjacent folded-plate roof panels 8, 8 of the folded-plate roof B (see Figures 3(C), 4(B), 5(A), etc.). Then, the worker holds the lower part of the eaves door A with both hands and sets it so that the connection port 2 of the connection upper part 12 is positioned below the screw shaft 32 of the mounting screw 3.

Next, the worker pushes the eaves door A upwards so that the screw shaft 32 of the mounting screw 3 is inserted into the insertion opening 21 of the connection port 2, and the screw shaft 32 passes through the insertion opening 21 of the connection port 2 (see (I) and (II) of Figure 5(A)). The worker then pushes the eaves door A upwards so that the lower end of the screw shaft 32 passes through the insertion opening 21 (see (I) and (II) of Figure 5(B)).

Furthermore, as the eaves door A is pushed up, the protruding piece 22 of the connection port 2 begins to bite into the screw groove (thread root) 32a of the screw shaft 32 (see (I) and (II) of Figure 5(C)), but it is continued to be pushed up until the connection upper part 12 abuts or nearly abuts the top of the angled part J of the folded plate roof B (see (I) and (II) of Figure 5(D)). At this time, the protruding piece 22 of the connection port 2 bites into the screw groove (thread root) 32a of the screw shaft 32 of the mounting screw 3, and the eaves door A can be attached and fixed to the angled part J of the folded plate roof B.

Figure 3 (E) is a partially cut-away side view of the eaves panel A attached to the eaves of the folded-plate roof B. In the figure, 91 is a tight frame, and 92 is a fitting retaining clip. The fitting retaining clip 92 is fixed onto the tight frame 91, and the two fitted bent portions 83, 83 of adjacent folded-plate roof panels 8, 8 are connected at a specified distance via the fitting retaining clip 92, and the fitting cap material 7 is fitted onto both fitted bent portions 83, 83.

Also, 93 is an exterior wall, and 94 is an eaves edge water-repellent material attached to the exterior wall 93. After the eaves edge door A is attached to the eaves edge of the folded-plate roof B, if necessary, the edge portion 14 of the eaves edge door A is fixed to the eaves edge water-repellent material 94 with fasteners such as screws, completing the installation of the eaves edge door A to the eaves edge of the folded-plate roof B. 95 is a structural material such as a steel frame, and the tight frame 91 is installed and fixed onto the structural material 95. This is performed for all supports, and the folded-plate roof B is constructed.

The adjacent eaves edge panels A, A that are attached to the eaves of the folded-plate roof B have a connecting protrusion 14a formed on one end of the edge 14 in the width direction, which is disposed on the back side of the edge 14 of the adjacent eaves edge panel A, and the connecting protrusion 14a is fixed with a fastener such as a screw (see Figures 3(A) and (E)). Furthermore, the edge 14 of the eaves edge panel A may be fixed to the eaves edge water drainage material 94 with a screw. The connecting protrusion 14a has a hole formed in advance for a fastener such as a screw.

In the present invention, the worker simply aligns the connection port 2 of the eaves door A in the present invention with the position of the screw shaft 32 of the mounting screw 3, which is pre-attached to the folded-plate roof B, which is constructed by connecting adjacent fitting-type folded-plate roof panels 8, 8 with the fitting cap material 7, and pushes the eaves door A upward, and the screw shaft 32 of the mounting screw 3 is inserted into the connection port 2 of the eaves door. Then, by continuing to push up the eaves door A in this state, the screw shaft 32 enters and penetrates the insertion opening 21 of the connection port 2, and the multiple protruding pieces 22, 22, ... of the connection port 2 bite into the screw groove portion (screw valley portion) 32a of the screw shaft 32, so that the eaves door A can be attached to the eaves of the folded-plate roof B very easily and quickly.

Furthermore, the protruding piece 22 of the connection port 2 bites into the thread groove (thread root) 32a of the screw shaft 32, so that the eaves door A can be fixed extremely firmly to the screw shaft 32 together with the connection port 2. In particular, once the protruding piece 22 of the connection port 2 bites into the thread groove (thread root) 32a of the screw shaft 32 of the mounting screw 3, its free end basically tilts and deforms downward, making it easier for the worker to push up the eaves door A further [see Figures 3(B), (C), and 5(B)].

Therefore, even if the eaves door A is pushed upward and collides with the tip of the screw shaft 32 of the mounting screw 3 screwed into the eaves of the folded-plate roof B, the mounting screw 3 does not move even slightly relative to the angled portion J. Therefore, the screw shaft 32 of the mounting screw 3 can be inserted into the connection port 2 of the eaves door A, and the eaves door A can be attached to the eaves.
