Description

[Technical Field]

[0001] The present invention relates to a folded plate roof material construction jig that can be installed on a predetermined receiving tool at a construction site of a long folded plate type roof and can easily and quickly arrange a long folded plate roof material between the predetermined receiving tools to construct a folded plate roof. [Background technology]

[0002] At a construction site for a large-area folded-plate metal roof, a molding machine for molding long, folded-plate roofing materials is first installed at the construction site of the building structure. This molding machine molds long, folded-plate roofing materials, and workers are assigned at appropriate intervals along the same direction as the longitudinal direction of the folded-plate roofing materials. The workers transport the roofing materials to the designated construction location on structural members such as steel beams, and install the roofing materials in the designated location. This process is repeated many times to construct a metal folded-plate roof.

[0003] There are already various devices that transport roofing materials to a predetermined installation position on a structural material by manually moving workers back and forth between the installation position of the molding machine and the installation position of the folded-plate roofing material molded by this molding machine, and the applicant has also developed a folding-plate roofing material transport device. However, after transporting the folded-plate roofing material to the predetermined position, in order to install this folded-plate roofing material on the predetermined receiving tool, it is necessary for many workers to lift the long folded-plate roofing material at the same time and place it in the predetermined position, and it is also necessary to align the longitudinal end of the folded-plate roofing material to the longitudinal end of the already installed folded-plate roofing material.

[0004] After transporting the folded-plate roofing material to the designated position, the task of placing the folded-plate roofing material is extremely troublesome and difficult. For this reason, various devices have been developed to place the folded-plate roofing material in the designated position of the receiving fixture. One example is shown in Patent Document 1.

[0006] As mentioned above, various types of construction conveyors have been developed, and examples of the main types are disclosed in patent documents. Most of the conventional conveyors, including the main ones, have extremely complex structures and are heavy. Furthermore, conventional conveyors are cumbersome to use, requiring a long time and skill for workers to become proficient in using them. Therefore, an object of the present invention is to provide a folding-plate roofing material installation jig that can easily, quickly, and with minimal effort install long folding-plate roofing materials formed by a molding machine in a predetermined position at a folding-plate roofing construction site. [Means for solving the problem]

The invention of claim 5 solves the above problem by providing a jig for installing folded plate roofing materials as set forth in claim 1 or 2, characterized in that the stopper is composed of two right-angled triangular block-shaped locking protrusions and is designed to be loosely inserted into the legs of the roof fixing member.

[0010] The invention of claim 6 solves the above problem by providing a jig for installing folded plate roofing materials, characterized in that in the jig for installing folded plate roofing materials described in claim 1 or 2, the stopper consists of a first stopper portion and a second stopper portion, the first stopper portion is deep and is used for loose insertion into the leg portion of the roof fixing member, and the second stopper portion is shallow and is used for loose insertion into the vertical portion of the connecting device on the roof.

[0011] The invention of claim 7 solves the above problem by providing a jig for installing folded plate roofing materials as described in claim 1 or 2, characterized in that the stopper consisting of two right-angled triangular block-shaped locking protrusions and the stopper consisting of the first stopper portion and the second stopper portion are removably attached to the swingable free end of the second base. [Effects of the Invention]

[0012] According to the invention of claim 1, by using multiple folded-plate roofing jigs of the present invention for new folded-plate roofing materials during the installation work of a folded-plate roof, the new folded-plate roofing material placed on the first base can be moved onto the second base with the extremely simple operation of tilting the first base. This allows the new folded-plate roofing material to be very easily and quickly placed in the designated position from the roofed area to the unroofed area, improving the efficiency of the folded-plate roof installation work. The folded-plate roofing material installation jig has an extremely simple configuration and can be easily used by even inexperienced workers. The second base is equipped with adjustment rollers, which make it easy to position the folded-plate roofing material in the designated position and to align the leading edge of the installed folded-plate roofing material with the leading edge of the new folded-plate roofing material (nose alignment).

[0013] To explain the above effects in detail, the corrugated plate roofing material installation jig of the present invention has a stopper attached to the swingable end of the second base, and the corrugated plate roofing material installation jig is placed at the top of the installed corrugated plate roofing material and the roof fixing member (which may also be called a receiving fixture or tight frame) in the roof uninstalled area, and the second base is engaged with the leg of the roof fixing member in the roof uninstalled position via the stopper, so that the corrugated plate roofing material installation jig can be stably positioned at the boundary between the installed roof area and the uninstalled roof area.

[0014] Furthermore, since the first base and the second base are arranged in series in the longitudinal direction and pivotally connected so that the first base and the second base can swing freely relative to each other, the second base is temporarily fixed to the roof fixing member by the stopper, so that the first base can swing freely relative to the second base. As a result, when a new folded-plate roof material is placed on the first base, the worker can tilt the first base along the longitudinal direction, and the new folded-plate roof material can be moved along the slope of the first base and then moved onto the second base.

[0015] The second base is provided with adjustment rollers, which allow it to be placed in a predetermined position on the unconstructed roof, and the new folded-plate roofing material can be moved longitudinally on the adjustment rollers to easily align the longitudinal end of the new folded-plate roofing material so that the leading edge of the existing folded-plate roofing material matches the leading edge of the new folded-plate roofing material (nose alignment).In this way, by providing multiple folded-plate roofing material installation jigs of the present invention, the work of installing new folded-plate roofing materials in unconstructed roof areas can be easily and quickly installed, significantly improving work efficiency.

[0016] In the invention of claim 2, by attaching the receiving roller so that the longitudinal direction and the axial direction of the first base are the same, it is possible to adjust the position along the longitudinal direction of the folded-plate roofing material placed on the first base. Furthermore, by using it when feeding a new folded-plate roofing material that is formed early from the start of construction from the roll forming machine along the longitudinal direction at the start of construction of the folded-plate roof, it is possible to smoothly feed the new folded-plate roofing material in the longitudinal direction.

[0017] In the invention of claim 3, the first base is provided with a handle, making it easy to lift the first base at an angle, and making the folded plate roofing material installation jig extremely easy to use.The invention of claim 4 makes it possible to prevent scratches on both the installed and new folded plate roofing materials during the installation of a folded plate roof.In the invention of claim 5, the stopper is composed of two right-angled triangular block-shaped locking protrusions, so that the folded plate roofing material installation jig of the present invention can be installed and fixed to the roof fixing member in a secure and stable state, making it easy to position the new folded plate roofing material in the installation position.

[0018] In the invention of claim 6, the stopper is composed of a first stopper portion and a second stopper portion, the first stopper portion is deep and is for loosely inserting into the leg portion of the roof fixing member, and the second stopper portion is shallow and is for loosely inserting into the vertical portion of the connector on a single-layer roof. This is a folded plate roof material installation jig characterized by the fact that the first stopper can be used for a single-layer folded plate roof, and the second stopper can be used for a two-layer folded plate roof. Therefore, whether it is the construction of a single-layer folded plate roof or a two-layer folded plate roof, by implementing this invention, it is sufficient, and there is an advantage that construction efficiency can be improved.

[0019] The invention of claim 7 is a jig for installing folded plate roofing materials according to claim 1 or 2, characterized in that the stopper consisting of two right-angled triangular block-shaped locking protrusions and the stopper consisting of the first stopper portion and the second stopper portion are detachably attached to the free swing end of the second base, thereby having the effect of being able to quickly respond to the type of folded plate roofing material installation jig you want to use.

DETAILED DESCRIPTION OF THE INVENTION

[0021] The present invention will be described below with reference to the drawings. The folded-plate roofing material installation jig A of the present invention is used mainly at a metal folded-plate roof construction site to transport a new folded-plate roofing material 8n from a completed section of the roof to a predetermined installation position in an unconstructed section of the roof using a transport means, and then place the new folded-plate roofing material 8n in the predetermined position in the unconstructed section of the roof (see Figure 3(A)). Furthermore, a known transport means is used to transport the new folded-plate roofing material 8n to the predetermined position. Below, the folded-plate roofing material installation jig A and the process of placing the new folded-plate roofing material 8n in the predetermined position using the folded-plate roofing material installation jig A will be described.

[0022] The folded plate roofing material installation jig A is a tool used at a construction site for installing a folded plate roof at a building site, by using the top ends of multiple already-installed folded plate roofing materials 8, 8, ... as a transport route from the installation start position to place a new folded plate roofing material 8n at an uninstalled position for the folded plate roofing materials 8, 8, ... that have already been installed in a predetermined position during construction work. During construction at a roof construction site, the installed folded plate roofing material 8 and the new folded plate roofing material 8n are folded plate-type metal roofing materials that are long in the longitudinal direction, generally about 50 m to about 100 m.

[0023] The folded plate roofing material 8 and the new folded plate roofing material 8n come in various types, such as a fastening type where the joints between adjacent roofing materials are fastened, a fitting type where a cap material is placed over the joints between adjacent roofing materials, and a polymerization type where the angled portions of adjacent roofing materials are overlapped. In the following explanation, the folded plate roofing material 8 and the new folded plate roofing material 8n will mainly be described as a fastening type (see Figures 3 to 5, etc.). The installed folded plate roofing material 8 will simply be referred to as the folded plate roofing material 8.

[0024] In addition, in the description of this invention, the "completed roof portion" refers to a portion where the installation of the folded-plate roofing material 8 has already been completed in the appropriate predetermined position on the roof fixing member 92 on the structural member 91 such as a beam. Therefore, the folded-plate roofing material 8 is the roofing material present in the already installed portion. Furthermore, the "uninstalled portion of the roof" refers to a portion at the roof construction site that has not yet been installed and where the roof is to be installed. In other words, it refers to the portion where the new folded-plate roofing material 8n will be placed and the roof will be installed (see Figures 3 and 4).

[0025] Therefore, once a new folded-plate roofing material 8n is placed in a predetermined position using the folded-plate roofing material installation jig A of the present invention and fixed to a roof fixing member 92 via a retaining clip 93 or the like, it is referred to as a folded-plate roofing material 8 already installed in a predetermined position. The roof fixing member 92 is sometimes referred to as a tight frame or a receiving device. The roof fixing member 92 is formed from a metal strip material, has a substantially trapezoidal shape, and has legs 92b, 92b formed on both widthwise sides of a receiving top portion 92a. The lower rung portion 84 of the folded-plate roofing material 8 is placed on the receiving top portion 92a, and the lower rung portion 84 is fixed to the receiving top portion 92a by a retaining clip 93.

[0026] The folded-plate roofing material 8 has rising side portions 82, 82 formed on both widthwise sides of a bottom main plate portion 81. The rising side portions 82, 82 have top surface portions 83, 83 that are slightly inclined or approximately horizontal toward the outside (see Figure 2(A)). One of the top surface portions 83 has a lower ledge portion 84 formed thereon, and the other top surface portion 83 has an upper ledge portion 85 formed thereon.

[0027] Here, the new folded-plate roof material 8n is substantially equivalent to the folded-plate roof material 8 already installed in the predetermined position, and each part of the new folded-plate roof material 8n is given the same symbol as the folded-plate roof material 8, and the new folded-plate roof material 8n also has a bottom main plate portion 81, rising side portions 82, 82, top surface portions 83, 83, lower run portions 84 and upper run portions 85 (see Figure 2(A)).

[0028] There are multiple embodiments of the folded plate roofing material installation jig A of the present invention, and the first embodiment will be described. The folded plate roofing material installation jig A includes a rectangular frame-shaped first base 1, a support roller 41, a rectangular frame-shaped second base 2, a position adjustment roller 42 attached so that the longitudinal direction and axial direction of the second base are the same, a stopper 5 attached to the swingable end of the second base, and a pivotal connection part 3 that pivotally connects the first base 1 and the second base 2 (see Figures 1 and 2(A)).

[0029] Here, the longitudinal direction of the jig A for installing folded plate roofing materials of the present invention refers to the direction in which the first base 1 and the second base 2 are connected in series (see Figure 1(A)). The width direction is the direction perpendicular to the longitudinal direction of the jig A for installing folded plate roofing materials in a plan view. The longitudinal and width directions of the jig A for installing folded plate roofing materials are shown in the main drawings. The first base 1 and the second base 2 are arranged in series in the longitudinal direction and pivotally connected via the pivotal connection part 3 so that the first base 1 and the second base 2 can freely swing relative to each other (see Figures 1(B) and 2(A)).

[0030] The first base 1 has a horizontal frame portion 11 and a vertical frame portion 12, which are combined at right angles to form a rectangular frame (see Fig. 1(A)). The horizontal frame portion 11 is a member that forms the longitudinal direction of the first base 1, i.e., the long side of the rectangle. The vertical frame portion 12 is a member that forms the short side of the rectangle of the first base 1 (see Figs. 1(A) and (E)).

[0031] The horizontal frame portion 11 and the vertical frame portion 12 are made of steel pipes with a square cross section, and it is preferable that the four corners are formed with an arc, i.e., a radius (see Figure 1(D)). The horizontal frame portion 11 and the vertical frame portion 12 are preferably made of a lightweight metal, such as aluminum, or thin-walled steel pipes. The vertical frame portion 12 and the horizontal frame portion 11 are connected and fixed by welding, or, when prefabricated parts are used in this invention, by fasteners such as bolts and nuts.

[0032] The second base 2 is substantially similar to the first base 1 and has a horizontal frame portion 21 and a vertical frame portion 22, which are combined at right angles to form a rectangular frame, with the horizontal frame portion 21 forming the long sides and the vertical frame portion 22 forming the short sides. The horizontal frame portion 21 and the vertical frame portion 22 are made of the same members and made of the same material as the horizontal frame portion 11 and the vertical frame portion 12 of the first base 1 (see Figures 1(A) and (D)).

[0033] The first base 1 and the second base 2 are arranged in series longitudinally and are pivotally connected via a pivotal connection part 3 (see Figs. 1(A) and (E)). The pivotal connection part 3 is provided on both widthwise sides of the first base 1 and the second base 2 (see Figs. 1(A) and (E)). The pivotal connection part 3 is composed of a first pivot piece 31, a second pivot piece 32, and a pivot shaft member 33. The pivotal connection part 3 is provided between the opposing short side parts (vertical frame part 12, vertical frame part 22) when the first base 1 and the second base 2 are pivotally connected.

[0034] The short side portions refer to the vertical frame portion 12 of the first base 1 and the vertical frame portion 22 of the second base 2. Specifically, the pivot connection portion 3 has first pivot pieces 31, 31 provided on both sides of the short side (vertical frame portion 12) of the first base 1, and second pivot pieces 32, 32 provided on both sides of the short side (vertical frame portion 22) of the second base 2 (see Figures 1(A) and (C)).

[0035] The outer end portion of the first pivot piece 31 is formed in a semicircular shape, and similarly, the outer end portion of the second pivot piece 32 is also formed in a semicircular shape. The first pivot piece 31 and the second pivot piece 32 are formed with pivot shaft holes 31a and 32a (see FIG. 1(C)). The first pivot piece 31 and the second pivot piece 32 are configured to overlap on both sides of the opposing short sides (vertical frame portion 12, vertical frame portion 22) of the first base 1 and the second base 2, and a pivot shaft member 33 is inserted into both pivot shaft holes 31a and 32a to pivotally connect the first pivot piece 31 and the second pivot piece 32. In the illustrated configuration, both first pivot pieces 31, 31 are positioned on the inner side of both second pivot pieces 32, 32, but the opposite configuration, where both first pivot pieces 31, 31 are positioned on the outer side of both second pivot pieces 32, 32, is also acceptable.

[0036] The pivot shaft member 33 may be a combination of a headed shaft member and a retaining ring, or a combination of a bolt and nut. The first base 1 and the second base 2 are configured to be able to pivot relative to each other via the pivot joint 3 (see Figures 1(B) and 2(A)). When the folded-plate roofing material installation jig A is actually used to install a new folded-plate roofing material 8n, the second base 2 is fixed to the leg 92b of the roof fixing member 92, and the first base 1 pivots relative to the second base 2 (see Figure 2(A)). The position of the pivot shaft member 33 at the pivot joint 3 is referred to as the pivot point P of the folded-plate roofing material installation jig A (see Figures 1(B), 2(A), and (B)).

[0037] The length of the first base 1 from the free swing end to the pivot point P is set longer than the distance between the lower and upper rungs 84 and 85 of the run-fastening type folded-plate roofing material 8 or the new folded-plate roofing material 8n (see Figure 2(A)). The length of the second base 2 from the pivot point P to the tip of the stopper 5 on the free swing end side is long enough to allow the stopper 5 on the free swing end side to engage with the leg 92b of the roof fixing member 92 and for the tip of the stopper 5 to abut the top surface of the structural material 91 (see Figures 2(A) and 2(C)). Although not specifically shown, the vertical frame 12 on the pivot joint 3 side in the longitudinal direction of the first base 1 may not be provided. This is applicable when the roller support frame 13 can also serve as the vertical frame 12.

[0038] The second base 2 is provided with a position adjustment roller 42 (see FIGS. 1A and 1E). The position adjustment roller 42 is mounted so that its axial direction is the same as the longitudinal direction of the second base. In other words, the axial direction of the position adjustment roller 42 is parallel to the horizontal frame portion 21. The position adjustment roller 42 is used when aligning one longitudinal end of the new folded-plate roofing material 8n with one longitudinal end of the existing folded-plate roofing material 8 when placing the new folded-plate roofing material 8n in a predetermined position in an unroofed area, i.e., when aligning the nose of the folded-plate roofing material 8n (see FIGS. 4 and 5). The position adjustment roller 42 protrudes from the upper surface of the second base 2. It is preferable that the position adjustment roller 42 not protrude from the lower surface of the second base 2.

[0039] The position adjustment roller 42 is disposed between the two horizontal frame portions 21, 21 within the frame body of the second base 2, and two roller support frames 23, 23 are provided parallel to each other so as to be parallel to the vertical frame portions 22, 22, with the position adjustment roller 42 provided between the two roller support frames 23, 23 (see FIG. 1(A)). The axial direction of the position adjustment roller 42 is configured to follow the longitudinal direction of the second base 2.

[0040] The position adjustment roller 42 has rotary support shafts 42a, 42a that protrude outward along the axial direction from both axial sides of the roller portion of the position adjustment roller 42 (see FIGS. 1(A) and 1(E)). Bearing holes are formed in both roller support frames 23, 23, and the rotary support shafts 42a on both axial sides of the position adjustment roller 42 are inserted into and fixed in the bearing holes of the roller support frame 23. Both rotary support shafts 42a, 42a of the position adjustment roller 42 are supported by both roller support frames 23, 23, allowing the roller portion of the position adjustment roller 42 to rotate freely.

[0041] A stopper 5 is provided at the free end of the second base 2, that is, on the opposite side of the pivot joint 3 in the longitudinal direction (see Figures 1(A), (B), and (E)). The stopper 5 is engaged with one leg 92b of a roof fixing member 92 provided at the unconstructed roof position where a new folded-plate roofing material 8n will be placed, thereby ensuring that the folded-plate roofing material installation jig A is installed in a stable state (see Figures 2(C) and (D)).

[0042] The stopper 5 is composed of two locking protrusions 51, 51 (see Figs. 1(A) and (E)), and is configured to clamp and lock one leg 92b of the roof fixing member 92 between the two locking protrusions 51, 51 (see Figs. 2(C) and (D)). The portions of the locking protrusions 51, 51 that clamp both widthwise sides of the leg 92b of the roof fixing member 92 are called clamping surfaces 51a (see Figs. 1(A), (E), 2(C) and (D)).

[0043] Specifically, the locking projection 51 is in the shape of a triangular block with a right-angled portion that is perpendicular to the vertical frame portion 22 of the second base 2, and both clamping surfaces 51a, 51a of the locking projections 51, 51 protrude outward at a right angle to the vertical frame portion 22 that corresponds to the short side of the free swing end of the second base 2 (see Figures 1(A), (E), 2(C), and (D)). The distance Wa between the clamping surfaces 51a, 51a of the locking projections 51, 51 is set so that the width dimension Wb of the leg portion 92b of the roof fixing member 92 can be clamped with a slight margin, and therefore the distance Wa is greater than the width dimension Wb.

[0044] More specifically, the distance Wa is set to be approximately 3 mm to 8 mm larger than the width dimension Wb, and is preferably approximately 5 mm (see FIG. 2(D)). The locking projections 51 of the stopper 5 are made of metal and are fixed to the vertical frame portion 22 on the swing-free end side of the second base 2 by fasteners such as bolts and nuts, or by welding. The locking projections 51 of the stopper 5 may also be made of synthetic resin such as plastic or hard rubber. In some embodiments, the locking projections 51 are generally L-shaped and are arranged along the short side of the swing-free end side of the second base 2, i.e., along the vertical frame portion 22 (see FIGS. 7(A), (B), (C), and (E)).

[0045] The receiving roller 41 is disposed between the two horizontal frame portions 11, 11 within the frame body of the first base 1, and two roller support frames 13, 13 are provided parallel to each other between the vertical frame portions 12, 12, with the receiving roller 41 provided between the two roller support frames 13, 13 (see FIGS. 1(A), (D), and (E)). The receiving roller 41 is configured to be mounted along the longitudinal direction of the first base 1 so that its axial direction is the same as the longitudinal direction of the first base 1. The receiving roller 41 protrudes from the upper surface of the first base 1. The receiving roller 41 may or may not protrude from the lower surface of the first base 1.

[0046] Like the position adjustment roller 42 described above, the receiving roller 41 has rotational support shafts 42a, 42a that protrude outward along the axial direction from both axial sides of its roller portion (see FIGS. 1(A) and 1(E)). It also has rotational support shafts 41a, 41a that protrude along the axial direction from both axial sides of its roller portion (see FIGS. 1(A), 1(D), and 1(E)). Bearing holes are formed in both roller support frames 13, 13, and the rotational support shafts 41a on both axial sides of the receiving roller 41 are inserted into and fixed in the bearing holes of the roller support frame 13. The rotational support shafts 41a, 41a of the receiving roller 41 are supported by both roller support frames 13, 13, allowing the roller portion of the receiving roller 41 to rotate freely.

[0047] A handle 14 may also be attached to the short side (vertical frame 12) on the swingable end side of the first base 1 (see Figure 1). When swinging the first base 1 relative to the second base 2, an operator can easily lift the first base 1 by holding the handle 14 and lifting it upward. Alternatively, the vertical frame 22 on the swingable end side of the first base 1 may also serve as the handle 14, thereby eliminating the need for a separate handle 14.

[0048] The receiving roller 41 serves to shift or move the new folded-plate roofing material 8n along the longitudinal direction. In particular, although not shown, the receiving roller 41 of the first base 1 serves to feed, along the longitudinal direction, the new folded-plate roofing material 8n that is formed early from the start of construction, such as the first or second one, fed from the roll forming machine (not shown) at the start of construction of the folded-plate roof, thereby facilitating the work of feeding the new folded-plate roofing material 8n along the longitudinal direction.

[0049] As a second embodiment of the present invention, which is a modification of the first embodiment, there is an embodiment in which a soft sheet material 6 is provided on both the upper and lower surfaces of the first base 1 and the second base 2 near the pivotal joints 3,3 (see FIG. 6). One end of the soft sheet material 6 is fixed to a portion of the first base 1 in the longitudinal direction and near the pivotal joint 3. The soft sheet material 6 is attached to the first base 1 so as to cover the pivotal joints 3,3. In addition, the soft sheet material 6 attached to the upper surface of the folded plate roofing material installation jig A is configured so as not to come into contact with the receiving roller 41 on the first base 1 side and the position adjustment roller 42 on the second base 2 side. In addition, the soft sheet material 6 attached to the underside of the folding roof material installation jig A is configured so as not to come into contact with the receiving roller 41 on the first base 1 side, and extends to approximately the middle position in the longitudinal direction of the second base 2 or approximately the middle position in the axial direction of the position adjustment roller 42, and the soft sheet material 6 does not come into contact with the position adjustment roller 42 (see Figures 6(A), (B), and (C)).

[0050] This prevents the new folded-plate roof material 8n from coming into direct contact with the pivotal joints 3, 3 during the process of moving from the first base 1 to the second base 2 (see Figure 6(D)). Adhesives or double-sided tape are used as the fastening means. A soft sheet material 6 is provided on the upper surface of the second base near the pivotal joints 3. The soft sheet material 6 is roughly hexagonal and extends in the longitudinal direction.

[0051] Although not shown, the soft sheet material 6 may be provided only on the lower surface or only on the upper surface. A synthetic resin such as polyethylene is used for the soft sheet material 6. When a new folded-plate roofing material 8n placed on the first base 1 by the folded-plate roofing material installation jig A is tilted by lifting the free end of the first base 1 and lowering the pivotal joint 3 side, the soft sheet material 6 allows the new folded-plate roofing material 8n to smoothly pass through the three pivotal joints when the new folded-plate roofing material 8n placed on the first base 1 is moved from the first base 1 side to the second base 2 side.

[0052] Furthermore, the soft sheet material 6 can prevent scratches on the new folded-plate roofing material 8n when it is moved from the first base 1 to the second base 2. Also, the soft sheet material 6 provided on the back side of the folded-plate roofing material installation jig A can prevent scratches on the already installed folded-plate roofing material 8. Furthermore, after the new folded-plate roofing material 8n has been placed in a predetermined position, it prevents scratches on the new folded-plate roofing material 8n when the folded-plate roofing material installation jig A is pulled away from the installation location of the new folded-plate roofing material 8n.

[0053] In other words, the soft sheet material 6 serves to protect both the already installed folded-plate roofing materials 8, 8, ... and the new folded-plate roofing material 8n that is about to be placed in its predetermined position from being scratched (see Figure 6(D)). Furthermore, as a third embodiment of the present invention, the support roller 41 may not be provided on the first base 1 (see Figure 7(A)).

[0054] Next, a construction method for installing a new folded-plate roofing material 8n in a predetermined position using the folded-plate roofing material installation jig A of the present invention will be explained mainly with reference to Figures 3 to 5. Here, for the convenience of explanation, a construction direction is set in the construction of a folded-plate roof. The construction direction is the direction in which the new folded-plate roofing material 8n is placed relative to the already installed folded-plate roofing material 8, and the construction direction is constant from the start to the end of construction.

[0055] The construction direction is indicated by arrows in Figures 2 to 5, and in these figures, the construction direction is unified from left to right. In this construction direction, in Figures 2 and 3, the folded-plate roofing material 8 to be installed and the new folded-plate roofing material 8n have the lower rung portion 84 located on the right side in the width direction and the upper rung portion 85 located on the left side in the width direction. In the construction of a folded-plate roof, multiple folded-plate roofing material construction jigs A of the present invention are prepared. The number of folded-plate roofing material construction jigs A is determined according to the longitudinal length of the folded-plate roofing material 8 and the new folded-plate roofing material 8n.

[0056] At the construction site of a folded plate roof, a plurality of folded plate roofing material installation jigs A of the present invention are installed at predetermined intervals along the longitudinal direction of the installed folded plate roofing material 8 on the end of the installed roof portion (see Figures 2, 3(A), 4(A-1), (A-2), 5(A-1), (A-2)). When installing the folded plate roofing material installation jig A on the folded plate roofing material 8, first, the width direction of the first base 1 of the installed folded plate roofing material 8 and the longitudinal direction of the folded plate roofing material installation jig A are aligned.

[0057] Then, the first base 1 of the corrugated plate roofing material installation jig A is positioned between the lower run portion 84 and the upper run portion 85 of the already installed corrugated plate roofing material 8, and the second base 2 engages the stopper 5 with one leg 92b of the next roof fixing member 92 while abutting the tip portion of the stopper 5 on the structural material 91 (see Figures 2(A), (C), Figures 3(A) to (C), Figure 4, etc.).

[0058] At this time, the longitudinal direction of the second base 2 forms an inclination with the pivot point P as the upper end and the free swing end side downward (see Fig. 2(A) and Figs. 3(A) to (C)). The stopper 5 of the second base 2 engages with the leg 92b of the roof fixing member 92, so that the second base 2 is fixed between the adjacent roof fixing members 92, 92 (see Fig. 2).

[0059] In addition, by shifting the position of the pivot point P of the folded plate roofing material installation jig A inward or outward by a small distance m with respect to the center line J of the lower run portion 84 of the installed folded plate roofing material 8, the top of the run of the lower run portion 84 will abut against the end of the pivot connection portion 3 of the first base 1 or second base 2, allowing for stable fixation of the folded plate roofing material installation jig and ensuring work stability (see Figure 2(B)). Note that the position of the pivot point P of the folded plate roofing material installation jig A may also be aligned with the center line J of the lower run portion 84 of the installed folded plate roofing material 8 (see Figure 7(G)).

[0060] The new folded-plate roofing material 8n, transported by a transport means to the vicinity of the unfinished portion of the folded-plate roof under construction, is placed on the first base 1 of multiple folded-plate roofing material installation jigs A, A, ... installed on the previously installed folded-plate roofing material 8 located at the end (see Figures 3(B), 4(B-1), (B-2), and 5(A-1), (A-2)). The first base 1 has a support roller 41, which allows for adjustment of the position back and forth along the longitudinal direction of the new folded-plate roofing material 8n, making it possible to roughly align the new folded-plate roofing material 8n. However, in this case, the support roller 41 is not used to align the longitudinal ends of the installed folded-plate roofing material 8 and the new folded-plate roofing material 8n; this task will be performed in the next step.

[0061] When the free swinging end side of the first base 1 is lifted with the pivot point P of the pivotal connection part 3 as the swing center, the first base 1 becomes inclined with the free swinging end side facing upward and the pivotal connection part 3 side facing downward (see Figure 3(C), Figure 4(B-1), (B-2)), and the new corrugated roof material 8n placed on the first base 1 slides down to the lower side of the inclined first base 1, and moves over the pivot point P of the pivotal connection part 3 to the second base 2 (see Figure 3(C), Figure 4(C-1), (C-2), Figure 5(C-1), (C-2)).

[0062] At this time, the lower run 84 of the new folded-plate roofing material 8n abuts or approaches the top end 92a, which is the upper end of the next roof fixing member 92 (see Figures 3(C), 4(C-1), (C-2), 5(C-1), and (C-2)). The new folded-plate roofing material 8n is then adjusted via the position adjustment roller 42 of the second base 2 so that its longitudinal leading edge coincides with the longitudinal leading edge of the previously installed folded-plate roofing material 8, which is offset L. This adjustment is sometimes referred to in the industry as "aligning the nose tip." Figure 5 shows the state in which the offset L between the previously installed folded-plate roofing material 8 and the new folded-plate roofing material 8n is being corrected (see Figures 5(A-1) to (C-1)).

[0063] Next, by pulling the folded-plate roofing material installation jig A away from between the installed folded-plate roofing material 8 at the end of the roof where the roof has already been installed and the new folded-plate roofing material 8n, the new folded-plate roofing material 8n can be positioned approximately accurately in the specified position (see Figure 3(D)). By pulling away the folded-plate roofing material installation jig A, the new folded-plate roofing material 8n will change its posture from a state in which it was tilted in the width direction between the adjacent roof fixing members 92, 92 to a horizontal position due to its own weight, and will return to the correct position.

[0064] Then, the new folded-plate roof material 8n placed on the folded-plate roof material installation jig A is properly positioned at the position of the roof fixing member 92 installed in the uninstalled position, and the lower run portion 84 of the new folded-plate roof material 8n is positioned at the top portion 92a of the roof fixing member 92 in the uninstalled position, and the lower run portion 84 is fixed to the top portion 92a of the roof fixing member 92 by the retaining clip 93 (see Figure 3(D)).

[0065] Next, the upper run portion 85 of the new folded-plate roofing material 8n is placed over the lower run portion 84 of the already installed folded-plate roofing material 8, and the overlapping lower run portion 84 and upper run portion 85 are fastened together. The new folded-plate roofing material 8n is then properly installed in the uninstalled position, becoming the installed folded-plate roofing material 8. By repeating this same process, the folded-plate roof is installed and the folded-plate roof is completed. By using the folded-plate roofing material installation jig A in the installation of a folded-plate roof, it is possible to properly position and install the new folded-plate roofing material 8n in the uninstalled position extremely easily and quickly, improving work efficiency.

[0066] Next, we will explain yet another embodiment of the folded plate roofing material installation jig A of the present invention. In this embodiment, in the first embodiment, the receiving roller 41 of the first base 1 is a conveying circular pipe member 41p, and the position adjustment roller 42 of the second base 2 is an adjusting circular pipe member 42p (see Figure 7(C)). In addition, the first base 1 does not use a receiving roller 41, and the horizontal frame portion 21 is inserted into the conveying circular pipe member 41p with some slack, so that the conveying circular pipe member 41p rotates around the horizontal frame portion 11 as a central axis (see Figures 7(C) and (D)).

[0067] Similarly, the second base 2 does not use position adjustment rollers 42, but inserts the horizontal frame 21 into the adjustment circular pipe member 42p with some clearance (also called loose insertion), so that the adjustment circular pipe member 42p rotates around the horizontal frame member 21 as its central axis. As mentioned above, the horizontal frame members 11 and 21 have square cross sections, and the four corners are rounded to form arc shapes. This allows the conveying circular pipe member 41p and the adjustment circular pipe member 42p to rotate easily (see Figure 7(D)).

[0068] In yet another embodiment, instead of using the receiving roller 41 or the conveying cylindrical member 41p of the first base 1 and the adjusting roller 42 or the adjusting cylindrical member 42p of the second base 2, a smooth sheet material 43 on the first base 1 side and a smooth sheet material 44 on the second base 2 side may be used (see FIG. 7(E)). The smooth sheet material 43 is attached to both lateral frame portions 11, 11 of the first base 1, and the smooth sheet material 44 is attached to both lateral frame portions 21, 21 of the second base 2.

[0069] The surfaces of the smooth sheet materials 43 and 44 are smooth surfaces with an extremely small coefficient of friction. The smooth sheet materials 43 and 44 are attached to the horizontal frame portions 11 of the first base 1 and the horizontal frame portions 21 of the second base 2 with an adhesive, or have adhesive backings which are attached to the horizontal frame portions 11 of the first base 1 and the horizontal frame portions 21 of the second base 2 (see Figures 7(E) and (F)).

[0070] In this embodiment, in the folding roof material installation jig A, a new folding roof material 8n is placed on the upper surface of the smooth sheet material 43 and the smooth sheet material 44 of the first base 1 and the second base 2, and the new folding roof material 8n can be placed in a predetermined position in the uninstalled part of the roof, just as if it were placed on the receiving roller 41 and the adjusting roller 42.

[0071] Next, as a modified example of the first embodiment of the present invention, there is a first base 1 and a second base 2 of the folded plate roofing material installation jig A of the present invention assembled using pipe materials made of steel pipes with a circular cross section and joint members (see FIG. 8). In the first base 1, horizontal pipe members 15, vertical pipe members 16 and joint members 17 made of steel pipes are used. Then, the horizontal pipe members 15 and the vertical pipe members 16 are connected by the joint members 17 to form a rectangular frame (see FIG. 8(A)).

[0072] Furthermore, when a receiving roller 41 is attached, two roller support pipes 18, 18 are attached to the frame of the first base 1 via joints 17, and the receiving roller 41 is provided between the roller support pipes 18, 18. When the first base 1 is made of pipe material, the pipe material itself can serve as the handle 14, but a separate handle 14 may also be provided. The second base 2 is also substantially similar to the first base 1, and uses horizontal pipes 25, vertical pipes 26, and joints 27 made of steel pipes. The horizontal pipes 25 and vertical pipes 26 are then connected by joints 27 to form a rectangular frame.

[0073] In this embodiment, as in the first embodiment, the first base 1 and the second base 2 are arranged in series in the longitudinal direction and are pivotally connected via a pivotal connection part 3 so that the first base 1 and the second base 2 can swing freely relative to each other. The pivotal connection part 3 is integrated with the joint material 17 on the first base 1 side and the joint material 27 on the second base 2 side, respectively, and a first pivot piece 31 is formed in the joint material 17 of the first base 1, and a second pivot piece 32 is integrated with the joint material 27 on the second base 2 side.

[0074] The first pivot pieces 31, 31 and the second pivot pieces 32, 32 are configured to overlap, and a pivot shaft member 33 is inserted into both pivot shaft holes 31a, 32a to pivotally connect the first pivot piece 31 and the second pivot piece 32. The pivot connection part 3 is configured (see Figure 8(A)). The pivot connection part 3 is substantially the same as the configuration of the pivot connection part 3 of the folded plate roofing material installation jig A of the first embodiment (see Figures 1(A), (B), (C), (E), Figures 2(A), (B)). Please refer to the description of the pivot connection part 3 in the first embodiment.

[0075] To install the position adjustment roller 42, the two roller support pipe members 28, 28 are installed within the frame body of the second base 2 via the joint member 27, and the position adjustment roller 42 is provided between the two roller support pipe members 28, 28. The stopper 5 of the second base 2 is directly connected to the tip end portions of the two horizontal pipe members 25, 25 on the swingable free end side.

[0076] Note that the horizontal pipe member 15 of the first base 1 in the modified example of the first embodiment corresponds to the horizontal frame portion 11 of the first embodiment, the vertical pipe member 16 in the modified example corresponds to the vertical frame portion 12 of the first embodiment, and the roller support pipe member 18 in the modified example corresponds to the roller support frame 13 of the first embodiment. Similarly, the horizontal pipe member 25 in the modified example of the first embodiment corresponds to the horizontal frame portion 21 of the first embodiment, the vertical pipe member 26 in the modified example corresponds to the vertical frame portion 22 of the first embodiment, and the roller support pipe member 28 in the modified example corresponds to the roller support frame 23 of the first embodiment.

[0077] As described above, the modified example of the first embodiment of the jig A for installing folded plate roofing materials differs only in the shape of the components, and the overall configuration is substantially the same as the first embodiment of the jig A for installing folded plate roofing materials. For the structure and usage, please refer to the explanation of the first embodiment of the jig A for installing folded plate roofing materials [see Figures 1(A), (B), (C), (E), Figures 2(A) and (B), and Figures 3 to 5].

[0078] 8(C) and 8(D) show another modification of the first embodiment, in which the horizontal pipe member 15 is inserted into the conveying circular pipe member 41p with some clearance (also called loose insertion), so that the conveying circular pipe member 41p rotates around the horizontal pipe member 15 as its central axis in the first base 1. Similarly, the horizontal pipe member 25 is inserted into the adjusting circular pipe member 42p with some clearance in the second base 2, so that the adjusting circular pipe member 42p rotates around the horizontal pipe member 25 as its central axis. As mentioned above, the horizontal frame portion 11 and the horizontal frame portion 21 have a square cross section, and the four corners are rounded to form an arc shape. This allows the conveying circular pipe member 41p and the adjusting circular pipe member 42p to rotate easily (see FIGS. 8(C) and 8(D)).

[0079] In particular, there was previously only one type of stopper 5, but this is an improvement to increase this to two types. Therefore, although there is of course the stopper 5 as a higher concept, there are also the first stopper 55 and the second stopper 56 as lower concepts. Therefore, hereinafter, the first stopper 55 and the second stopper 56 as the improved stopper 5 will be described with reference to FIGS. 9 to 12. FIG.

[0080] As shown in Figures 9(A) to 9(D), the stopper 5 is made up of a first stopper 55 and a second stopper 56. The first stopper 55 is deep and has a roughly U-shape so that it can be loosely inserted (for loose insertion) into the leg 92b of the roof fixing member 92. The inner surfaces of both sides are formed as clamping surfaces 55a, 55a, and the abutting surface at the depth is formed as a stopper surface 55b. As shown in Figure 11, the first stopper 55 is used when laying a single-layer folded-plate roof (the first folded-plate roof to be laid on the roof).

[0081] The second stopper 56 is shallow and is configured for loose insertion into the vertical portion of the connector 95 on an already laid single-layer folded-plate roof 8A (the first folded-plate roof to be laid on the roof). The inner surfaces of both sides are formed as clamping surfaces 56a, 56a, and the shallow abutment surfaces are formed as stopper surfaces 56b, and a gap 56c is also formed. As shown in Figure 12, the second stopper 56 is used when laying a two-layer folded-plate roof 8B (a double folded-plate roof laid on top of the roof) that is laid on top of the single-layer folded-plate roof 8A.

[0082] As described above, the first stopper portion 55 is a portion that is mainly used when constructing a single-layer folded-plate roof 8A (lower-layer folded-plate roof), and the second stopper portion 54 is a portion that is mainly used when constructing a two-layer folded-plate roof 8B (upper-layer folded-plate roof). By implementing this invention, the greatest advantage is that the same type of folded-plate roofing material construction jig A can be used for both buildings where only a single-layer folded-plate roof 8A (lower-layer folded-plate roof) is constructed and buildings where a two-layer folded-plate roof 8B (upper-layer folded-plate roof) is also constructed.

[0083] First, as shown in Figure 11, a construction jig A for a folded plate roof, which is provided with the first stopper portion 55 and the second stopper portion 56, is used. First, it is used when the folded plate roof is a single layer. The construction state in Figure 11 is the same as the construction state in Figures 2 and 3. In other words, the folded plate roofing material construction jig A is used at the construction site of a folded plate roof at a building site to use the top ends of multiple folded plate roofing materials 8, 8, ... that have already been installed from the construction start position as a transport path, and to place a new folded plate roofing material 8n in an unconstructed position for the folded plate roofing materials 8, 8, ... that have already been installed in a predetermined position during construction work.

[0084] Specifically, as shown in Figures 11(A-1) and 9(C), the first stopper 55 of the stopper 5 is loosely inserted between the clamping surfaces 55a, 55a into the leg 92b of the roof fixing member 92 installed on the structural member 91 (beam) (loose insertion). Then, a new folded-plate roofing material 8n transported by a transport means to the vicinity of the unfinished portion of the folded-plate roof under construction is placed on the first base 1 of multiple folded-plate roofing material installation jigs A, A, ... installed on the previously installed folded-plate roofing material 8 located at the end (Figures 11(A) and 3(B)). The first base 1 has a receiving roller 41, which adjusts the position back and forth along the longitudinal direction of the new folded-plate roofing material 8n to roughly align the new folded-plate roofing material 8n.

[0085] Then, when the free swing end side of the first base 1 is lifted with the pivot point P of the pivot connection part 3 as the swing center, the first base 1 becomes inclined with the free swing end side facing upward and the pivot connection part 3 side facing downward, and the new corrugated roof material 8n placed on the first base 1 slides down to the lower side of the inclined first base 1 and moves over the pivot point P of the pivot connection part 3 to the second base 2 (see Figure 11(B) and Figure 3(C)).

[0086] Next, the new folded-plate roofing material 8n is adjusted using the position adjustment roller 42 of the second base 2 so that its longitudinal tip coincides with the longitudinal tip of the installed folded-plate roofing material 8, which is offset L. It is essential to correct the tip position offset in this way. Once this adjustment is complete, the folded-plate roofing material installation jig A is immediately removed from between the installed folded-plate roofing material 8 at the end of the roof and the new folded-plate roofing material 8n (see the right side of Figure 11(C) and the right side of Figure 3(D)).

[0087] This allows the new folded-plate roofing material 8n to be positioned approximately accurately in the specified position (see Figures 11(C) and 3(D)). By pulling away the folded-plate roofing material installation jig A, the new folded-plate roofing material 8n, which was tilted in the width direction between the adjacent roof fixing members 92, 92, changes its posture by its own weight to a horizontal position and can be placed in the correct position. In this way, the single-layer folded-plate roof 8A can be installed using the first stopper 55.

[0088] Next, as shown in FIG. 12, the second stopper portion 56 is used when the folded-plate roof is two-layered. In other words, the folded-plate roofing material installation jig A is used to install a two-layer folded-plate roof 8B on an already installed single-layer folded-plate roof 8A at a construction site. As shown in FIG. 12(A), it is assumed that the single-layer folded-plate roof 8A has already been installed. Above this, the tops of the multiple folded-plate roofing materials 8, 8, ... that have already been installed from the installation start position are used as a transport path, and a new folded-plate roofing material 8n is placed in an uninstalled position relative to the folded-plate roofing materials 8, 8, ... that have already been installed in a predetermined position during the installation work.

[0089] Specifically, as shown in Figures 12(D) and (D-1), the second stopper 56 of the stopper 5 is loosely inserted between the clamping surfaces 56a, 56a into the vertical portion of the support 95 installed at the fastening point of the single-layer folded-plate roof 8A (loose insertion). Then, a new folded-plate roofing material 8n transported by a transport means to the vicinity of the unfinished portion of the folded-plate roof under construction is placed on the first base 1 of multiple folded-plate roofing material installation jigs A, A, ... installed on the previously installed folded-plate roofing material 8 located at the end (left side of Figure 12(D)). The first base 1 has a receiving roller 41, which adjusts the position back and forth along the longitudinal direction of the new folded-plate roofing material 8n to roughly align the new folded-plate roofing material 8n.

[0090] Then, when the free swing end side of the first base 1 is lifted with the pivot point P of the pivot connection part 3 as the swing center, the first base 1 becomes inclined with the free swing end side facing upward and the pivot connection part 3 side facing downward, and the new corrugated roof material 8n placed on the first base 1 slides down to the lower side of the inclined first base 1 and moves over the pivot point P of the pivot connection part 3 to the second base 2 (Figure 12 (E)).

[0091] Next, the new folded-plate roofing material 8n is adjusted using the position adjustment roller 42 of the second base 2 so that its longitudinal tip coincides with the longitudinal tip of the installed folded-plate roofing material 8, which is offset L. It is essential to correct this tip position offset. Once this adjustment is complete, the folded-plate roofing material installation jig A is immediately removed from between the installed folded-plate roofing material 8 at the end of the roof and the new folded-plate roofing material 8n (Figure 12(F)).

[0092] This allows the new folded-plate roofing material 8n to be positioned approximately accurately in the specified position. By pulling away the folded-plate roofing material installation jig A, the new folded-plate roofing material 8n, which was tilted in the width direction between the adjacent roof fixing members 92, 92, changes its posture by its own weight to a horizontal position and can be placed in the correct position. In this way, the single-layer folded-plate roof 8A can be installed using the first stopper 55 (see the right side of Figure 12(F)).

[0093] In this way, the invention configuring the stopper 5 having the first stopper 55 and the second stopper 56, even if it is an invention configuring the stopper 5 having the aforementioned locking protrusion 51, is in the relationship of a constituent part of a subordinate concept of the stopper 5 of the present invention. Also, although not shown in the drawings, the stopper 5 having the first stopper 55 and the second stopper 56 and the stopper 5 having the locking protrusion 51 may be detachably provided at the tip of the folded plate roofing material installation jig A.

[0094] In the above explanation, the depth of the first stopper 55 and the second stopper 56 at the tip of the folded plate roofing material installation jig A is determined appropriately according to the shape of the one-layer folded plate roof 8A and the two-layer folded plate roof 8B. The spacing between the first stopper 55 and the second stopper 56 is also determined appropriately according to the shape of the one-layer folded plate roof 8A and the two-layer folded plate roof 8B and the shape of the support 95. Furthermore, depending on the convenience of the construction site and the type of folded plate roof panel to be installed, the first stopper 55 may be used when installing the two-layer folded plate roof 8B, and the second stopper 56 may be used when installing the single-layer folded plate roof 8A.
