Embodiments for Carrying Out the Invention

[0010] The roof installer of the present invention and the roof structure using the roof installer will be described with reference to the drawings. The drawings are schematically drawn and may be different from the actual ones. In the description of a plurality of embodiments, the content described in one embodiment may be omitted in other embodiments.

[0011] [Embodiment 1] The roof installer 10 shown in FIGS. 1, 2, and 3 is a metal fitting for installing roof constituent members above or in the vicinity of the upper part of the column 12. By attaching roof constituent members to the roof installer 10, the roof structure 14 shown in FIG. 4 is formed.

[0012] The support column 12 is a cylindrical or rod-shaped body that stands vertically with respect to the ground or the like. For example, the support column 12 may be the support column of a scaffold installed around the building 16 at a construction site or the like. If it is the support column of a scaffold, the intervals between the support columns 12 will be constant. The cross-section of the support column 12 is circular. By attaching the roof installation tool 10 to the support column 12 of the scaffold and further attaching the members that make up the roof, a roof structure 14 can be provided on the scaffold (Figure 4). The roof structure 14 on the scaffold functions as rain protection, light shielding, or both.

[0013] The roof installation tool 10 includes a support column side joint 18 attached to the upper part of the support column 12 and a roof side joint 20 that is inclined with respect to the support column 12.

[0014] The support column side joint 18 is a cylindrical body made of metal. The length direction of this cylindrical body coincides with the length direction of the support column 12. The upper part 22 of the support column 12 is inserted into the support column side joint 18. A hole 24 is drilled in the upper part 22 of the support column 12. A hole 26 is also provided in the support column side joint 18, and the hole 24 of the support column 12 and the hole 26 of the support column side joint 18 coincide. A bolt, pin, or the like may be passed through the hole 24 of the support column 12 and the hole 26 of the support column side joint 18 so that the support column side joint 18 is fixed to the support column 12. In the case of a bolt, a nut may be used to prevent the bolt from coming out of the holes 24 and 26.

[0015] The roof side joint 20 is a cylindrical body made of metal. The length direction of this cylindrical body is inclined with respect to the length directions of the support column 12 and the support column side joint 18. A sheet holding member 28 is attached to the roof side joint 20. In Figure 1, one end 30 of the sheet holding member 26 is inserted and attached into the roof side joint 20. A hole 32 is drilled in one end 30 of the sheet holding member 28. This hole 32 coincides with the hole 34 of the roof side joint 20. A bolt, pin, or the like may be passed through these holes 32 and 34 so that the sheet holding member 28 is fixed to the roof side joint 20. In the case of a bolt, a nut may be used to prevent the bolt from coming out of the holes 32 and 34.

[0016] The column-side joint 18 and the roof-side joint 20 are attached by a connecting portion 36. For example, the connecting portion 36 includes two first plate bodies 38 attached to the column-side joint 18, a second plate body 40 attached to the roof-side joint 20 and disposed between the two first plate bodies 38, holes (not shown) provided in the first plate bodies 38 and the second plate body 40 respectively, and bolts 42 passing through these holes. A nut 44 may be attached to the shaft of the bolt 42 to fix the first plate body 38 and the second plate body 40. The shaft of the bolt 42 of the connecting portion 36 serves as a rotation axis, and the roof-side joint 20 rotates. The roof-side joint 20 can rotate with respect to the column-side joint 18. The relative angle between the column-side joint 18 and the roof-side joint 20 can be continuously changed. The angle of the sheet holding member 28 attached to the roof-side joint 20 can be freely set. Note that other configurations may be used as long as the angle of the roof-side joint 20 can be continuously changed.

[0017] When using the bolt 42 and the nut 44 as described above, the first plate body 38 and the second plate body 40 are brought into contact with each other by the bolt 42 and the nut 44 and fixed to each other. The angle of the roof-side joint 20 with respect to the column-side joint 18 can be fixed. Note that the method of fixing this angle is not limited, and any means for fixing the angle may be provided in the connecting portion 36.

[0018] The members constituting the roof include a sheet holding member 28 and a sheet 46. By attaching the sheet holding member 28 to the roof installation tool 10 and further attaching the sheet 46, the roof structure 14 shown in FIGS. 4, 5, and 6 is formed.

[0019] The sheet holding member 28 is a linear cylindrical body or rod body. The sheet holding member 28 is made of metal or resin. One end 30 of the sheet holding member 28 is attached to the roof-side joint 20. The other end 48 of the sheet holding member 28 is not attached anywhere and is disposed in space. At the construction site, the other end 48 of the sheet holding member 28 may be brought into contact with a wall of the building 16 or the like.

[0020] A plurality of columns 12 are arranged at equal intervals. By attaching the roof installation tool 10 to each column 12 and further attaching the sheet holding member 28, a structure in which the sheet holding members 28 are arranged is formed (Figs. 5 and 6). Note that adjacent columns 12 may be fixed by other columns facing the horizontal direction or the like.

[0021] The cross-section of the sheet holding member 28 may be smaller than that of the column 12. This is to make the sheet holding member 28 lighter and easier to stabilize the column 12. When the sheet holding member 28 is tubular, its thickness may be reduced to make it lightweight. The sheet holding member 28 may be made of a material lighter than the column 12.

[0022] A receiving member 50 that receives the other end 48 or the vicinity thereof of the sheet holding member 28 from below may be provided (Figs. 4 and 7). The receiving member 50 includes a recess 52 and a straight portion 54 for receiving the sheet holding member 28. The recess 52 has a depression 56, and the sheet holding member 28 fits into the depression 56. The straight portion 54 is composed of a linear rod or a cylindrical body, with the recess 52 attached to one end and the other end installed on the ground or the eaves or the like. The straight portion 54 may be configured to be telescopic so that its length can be changed. The other end 48 or the vicinity thereof of the sheet holding member 28 can be supported from below, making the position of the sheet holding member 28 easier to stabilize. It becomes easier to keep the angle of the sheet holding member 28 constant. Note that the structure of the receiving member 50 may be other structures as long as it can receive the sheet holding member 28.

[0023] The sheet 46 is placed on the sheet holding members 28 arranged side by side. A cord or the like may be attached to the sheet 46, the cord is wound around the sheet holding member 28, and the sheet 46 may be attached to the sheet holding member 28.

[0024] The seat attachment member 58 may be arranged at the other end 48 of the seat holding member 28 or in the vicinity thereof. The seat attachment member 58 is a linear rod or cylinder. Attach a cord body 60 or the like to the seat 46, and wind the cord body 60 around the seat attachment member 58. It is possible to prevent the seat 46 from coming off the seat holding member 28. A stop member 62 may be provided on the seat holding member 28 so that the seat attachment member 58 does not roll off the seat holding member 28. The stop member 62 is a rod or a plate or the like and is arranged on the seat holding member 28. Even if the seat attachment member 58 tries to roll on the seat holding member 28, the stop member 62 catches and prevents the seat attachment member 58 from rolling. The stop member 62 may be provided on the seat attachment portion 58 to prevent the seat attachment portion 58 from rolling.

[0025] The seat 46 is a flexible sheet-like object, and it is preferably made of a material that does not allow rainwater to pass through. By arranging the seat 46 above the scaffold, work can be performed even on rainy days. The seat 46 may have light-shielding properties. The seat 46 blocks direct sunlight on sunny days, making it easier to suppress the exhaustion of the operator's physical strength.

[0026] As described above, in the present invention, a roof structure 14 can be provided on the support 12 of the scaffold or the like, and work can be performed even on rainy days. Delays in work due to the weather are less likely to occur. Since the seat 46 is used for the roof structure 14, it is easy to attach and remove and easy to carry.

[0027] [Embodiment 2] The sheet holding member 28 is not limited to being composed of a rigid member. Part or all of the sheet holding member 28 may be composed of a flexible resin. For example, like the sheet holding member 64 in FIG. 8, the portion 66 attached to the roof side joint 20 is composed of a rigid member, and the other portion 68 is composed of a flexible resin. The resin portion is a cylindrical body with both ends closed. When air is introduced into the above-mentioned other portion 68, it becomes linear. A check valve may be attached to the portion where air is introduced. The check valve allows air to pass through and enter, and can prevent air from escaping from the above-mentioned other portion 68. Since compressors are installed at many construction sites, the compressor can be used to introduce air. When carrying the sheet holding member 64, air can be exhausted, making it light and easy to carry.

[0028] [Embodiment 3] The sheet 46 is not limited to being placed on the sheet holding member 28. For example, the sheet 46 may be directly attached to the sheet holding member 28. The work of attaching the sheet 46 to the sheet holding member 28 is omitted.

[0029] [Embodiment 4] Like the roof installation tool 70 shown in FIG. 9, two roof side joints 20 may be arranged and fixed (FIG. 9). One or two sheet holding members 28 can be attached to one roof installation tool 70 (FIG. 10). When two sheet holding members 28 are attached, the two sheet holding members 28 are arranged side by side.

[0030] Generally, the width of the building 16 varies for each construction site, and the number of scaffolding columns 12 also varies depending on the construction site. The columns 12 are arranged at regular intervals. Therefore, depending on the number of columns 12 arranged, the length of the sheet 46 in the direction in which the columns 12 are arranged is different. It is difficult to own all the sheets 46 with different lengths. As shown in FIG. 11, one set consists of one sheet 72 and sheet holding members 28 attached to both sides of the sheet 72. The length of one sheet 72 in the width direction (the direction in which the columns 12 are arranged) is made the same as or slightly longer than the length when the roof side joint 20 is arranged. The number of sets required to form the roof structure 14 is the number obtained by subtracting 1 from the number of columns 12. It is not necessary to have sheets 46 with different lengths, and the versatility is increased.

[0031] In order to eliminate the gap between the two sheet holding members 28 attached to one roof installer 70, fixing means for fixing the sheet holding members 28 to each other may be provided. For example, examples of the fixing means include a string, a band, a hook-and-loop fastener, etc. By fixing the two sheet holding members 28 to each other, it becomes easier to prevent rain leakage from the gap.

[0032] [Embodiment 5] The present invention is not limited to the form used beside the building 16. For example, as shown in FIGS. 12 and 13, roof installers 10 may be attached to the columns 12 arranged in the first row 74 and the columns 12 of the second row 76 arranged in parallel with the first row 74, respectively. One column 12 of the mutually facing rows 74 and 76 is arranged to face each other. One end of the sheet holding member 78 is attached to the roof installer 10 in the first row 74, and the other end of the sheet holding member 78 is attached to the roof installer 10 in the second row 76. The sheet holding member 78 is arranged so as to span between the columns 12 of the first row 74 and the columns 12 of the second row 76. A sheet 80 is arranged so as to be placed on or attached to the sheet holding member 78, and a roof structure 82 is formed. The center of the sheet holding member 78 may be curved. It becomes easier to place the sheet 80 on the sheet holding member 78, and the sheet 80 is less likely to be damaged.

[0033] The roof structure 82 can be installed not only at the construction site but also at any place where the support column 12 can be erected, such as on the ground or an open space. If a mechanism for adjusting the length is provided on the support column 12, the roof structure 82 can be installed even on an inclined site. Even in the configurations of FIGS. 12 and 13, a roof structure may be installed to cover the roof of the building 16 as well.

[0034] [Embodiment 6] As shown in FIGS. 14 and 15, the present invention may include a rail 84 attached to the upper portions of a plurality of support columns 12 arranged in a row, and a moving part 86 that moves along the rail 84. The support column side joint 18 of the roof installer 10 is attached to the moving part 84. A circular or square steel pipe can be used for the cross-section of the rail 84. If the rail 84 is attached to the support column 12, the attachment method is arbitrary. For example, as shown in FIG. 15, the rail 84 is attached to the support column 12 using a rail fixture 88. The rail fixture includes an annular part 90 that goes around the rail 84 and a detailed part 92. The annular part 90 is attached to the rail 84, and the detailed part 92 is attached to the support column 12.

[0035] The configuration of the moving part 86 is not limited as long as it can move along the rail 84. For example, it may be in a strip shape along the outer shape of the rail 84 and have an opening 94 at the bottom. If the cross-section of the rail 84 is circular, the cross-section of the moving part 86 is in a C shape. It can pass through the annular part 90 located at the part of the support column 12 without coming off the rail 84. When passing through the annular part 90, the opening 94 passes through the part with the detailed part 92.

[0036] [Embodiment 7] The roof-side joint 20 is not limited to the above form. As shown in FIG. 16, it may be a two-port joint member 96 in which two roof-side joints 20 are arranged and fixed. An insertion member 98 having the same shape as one end 30 of the sheet holding member 28 is attached to the two-port joint member 96. As shown in FIG. 17, the insertion member 98 is inserted into the roof-side joint 20 as shown in FIG. 1, etc., and the two-port joint member 96 is attached. The roof installation tool 10 provided with one roof-side joint 20 in FIG. 1 has the same configuration as the roof installation tool 70 in FIG. 9 provided with two roof-side joints 20 by using the two-port joint member 96 in FIG. 16. The insertion member 98 may be provided with holes 32 as in the first embodiment and may be attached to the roof-side joint 20 with bolts or the like and fixed.

[0037] The method of attaching the roof-side joint 20 to the connecting portion 36 is not limited, and it may be directly attached to the connecting portion 36 or may be attached via other members. Further, the number of roof-side joints 20 attached to the connecting portion 36 is not limited to one, and two may be used. In the case of two, the two-port joint member 96 may be directly or indirectly attached to the connecting portion 36.

[0038] [Embodiment 8] The connection between the column-side joint 18 and the roof-side joint 20 of the roof installation tool 10 is not limited to the above method. For example, the connecting portion 36 does not have a rotating shaft, and a ball joint may be used. The angle of the roof-side joint 20 with respect to the column 12 can be continuously and freely changed.

[0039] As in the roof installation tool 100 in FIG. 18, a configuration may be adopted in which the connecting portion 102 does not have a rotating mechanism and the angle of the roof-side joint 18 with respect to the column 12 is fixed. The strength of the roof installation tool 100 is increased.

[0040] [Embodiment 9] The column-side joint 18 is not limited to being tubular. As long as it is attached to the column 12, its shape can be arbitrary. For example, the column-side joint 18 may be composed of a rod and fitted into the column 12. The roof-side joint 20 is also not limited to being tubular. As long as the sheet holding member 28 is attached, its shape is not limited. The roof-side joint 20 may be composed of a rod and the sheet holding member 28 may be fitted into it.

[0041] The column-side joint 18 and the roof-side joint 20 are not limited to metal products. As long as the strength is guaranteed, reinforced resin or the like may be used.

[0042] In addition, the present invention can be implemented in various modified, corrected, and changed forms based on the knowledge of those skilled in the art without departing from the gist thereof. The described multiple embodiments are not separate and independent, and can be implemented by appropriately combining them based on the knowledge of those skilled in the art.
