Abstract
Description
Technical Field
[0001] The present invention relates to a roof pipe holder, a roof support column, a roof scaffold, and a roof safety fence installed on an inclined roof.
Background Art
[0002] On the roof of a building, various equipment and devices such as solar panels and outdoor units are installed, and the roof itself is also repaired. At that time, scaffolds, safety fences, etc. (hereinafter referred to as "scaffolds, etc.") for workers to work on the roof are installed. In that case, various proposals have been made from the viewpoints of ease and safety when installing scaffolds, etc. on an inclined roof. For example, Patent Document 1 (Japanese Patent Publication No. 2000-320134) describes a roof scaffolding 11 consisting of a tread 12 and a pair of left and right roof scaffolding brackets 13 for supporting the tread 12 on both sides, wherein the roof scaffolding bracket 13 includes a horizontal member 14 for being attached to the side of the scaffolding tread 12, a front leg 15, a rear leg 16 and a connecting leg 17 for supporting the horizontal member 14 in the horizontal direction, and the front leg 15 and the rear leg 16 are mounted... It consists of a scaffolding member 18 for the purpose of fixing the roof scaffolding 11 to a support column 52 arranged along the surface of the roof 51 at the lower end of the front leg 15, and an attachment part 20 for attaching to the support column 52 at the lower end of the rear leg 16, and the front leg 15 is rotatably connected to a first projection 24 protruding from the lower surface of one end of the horizontal member 14 by a first connecting part 26 provided at its upper end, and the connecting leg 17 is A roof scaffolding 11 is disclosed, in which a second connecting portion 27 provided at the upper end of a horizontal member 14 rotatably connects to a second projection 25 protruding from the lower surface of the other end of the horizontal member 14, a cylindrical upper support pipe 28 is positioned below the second connecting portion 27, a substantially cylindrical lower support pipe 30 is slidably fitted inside the upper support pipe 28, a cylindrical support tube 34 is positioned below the upper support pipe 28 in contact with the lower end edge of the upper support pipe 28, the rear leg 16 is rotatably connected to a third projection 36 protruding from below the lower support pipe 30 by a third connecting portion 37 provided at its upper end, the other end of the erection member 18 is fixed below the third connecting portion 37, and a substantially inverted U-shaped attachment portion 20 protrudes from the lower end of the rear leg 16 and is attached so as to straddle the support column 52.
[0003] In the roof scaffolding 11 of this Patent Document 1, the upper support pipe 28 is slidably fitted into the lower support pipe 30, and the support cylinder 34 that supports the upper support pipe 28 is configured to be able to move up and down relative to the lower support pipe 30 and to be fixed at the same time. As a result, the length of the connecting leg 17 can be easily adjusted, and the scaffolding treads 12 can be easily fixed in the horizontal direction. Furthermore, since the first to third protrusions 24, 25, and 36 and the first to third connecting parts 26, 27, and 37 are rotatably connected, it is possible to effectively prevent excessive stress from being applied to each member constituting the roof scaffolding bracket 13 when adjusting the length of the connecting leg 17. However, in the roof scaffolding 11 of Patent Document 1, the lower ends of the front legs 15 and the lower ends of the rear legs 16 are fixed to the support columns 52 which are arranged along the surface of the roof 51. Therefore, when installing the roof scaffolding 11, it is necessary to arrange the support columns 52 along the surface of the roof 51, which makes the structure complex and requires a great deal of effort to arrange the support columns 52 on the surface of the roof 51. Furthermore, there is a problem that the roof scaffolding 11 cannot be installed on roofs where it is not possible to arrange the support columns 52.
[0004] Patent Document 2 (Japanese Patent Publication No. 2001-248299) describes a support column a for constructing scaffolding on a roof, comprising a main rod 1 made of a square pipe and a secondary rod 2 divided into an upper secondary rod 2A and a lower secondary rod 2B made of a square pipe, wherein both secondary rods 2A and 2B have reverse threads at both ends and are screwed together via corresponding nuts 5 to a screw shaft 4 with a rotating rod 3 integrated in the center, the upper secondary rod 2A is rotatably clamped with bolts and nuts to the other end of a pair of connecting plates 6, 6 which sandwich the upper part of the main rod 1 from the left and right and have one end integrated, and the lower secondary rod 2B is A support column a for constructing scaffolding is disclosed, in which a rotor 8 is rotatably clamped and joined to the other ends of a pair of connecting plates 7, 7 with bolts and nuts, a swinging plate 10 is pivotally attached to the rotor 8 so as to be swingable, the swinging plate 10 is provided with a clamping portion 12 that has an opening 11 parallel to the mounting surface of the swinging plate 10 on the rotor 8 and has an opening at its lower end that can be widened and narrowed, and a clamping portion 18 that has an opening 17 at its lower end that can be widened and narrowed, and the clamping portion 18 is provided with a front clamping plate 19 and a rear clamping plate 20 that face the sub-rod 2. The scaffolding support column a of this Patent Document 2 is used on various metal sheet roofing surfaces. When used on a metal sheet roof with flat metal sheets laid vertically, the lower end of the main rod 1 is fixed to a snow guard 38 which is fixed to a standing seam 37 which is the attachment point to the roof surface, and the lower end of the lower secondary rod 2B is fixed to the standing seam 37. When used on a metal sheet roof with flat metal sheets laid horizontally, the lower end of the main rod 1 is fixed to a snow guard 42 which is fixed to a flat seam 41 which is the attachment point to the roof surface, and the lower end of the lower secondary rod 2B is similarly fixed to a snow guard 42 which is fixed to a flat seam 41.
[0005] Furthermore, Patent Document 2 discloses a scaffolding support column b in which a main rod 1 has a roof surface pressing portion 26 with a bifurcated leg 30 positioned below it, and a ski-shaped locking plate 47 is attached to its lower end instead of a clamping portion 18. In this scaffolding support column b, the locking plate 47 at the lower end of the main rod 1 is in contact with the lower surface of the fascia board 48 at the eaves, with the bent portion 49 at its tip standing upright on the back surface of the fascia board 48. The bifurcated leg 30, which straddles the vertical seams 37 of the roofing, is pressed from the upper surface of the roof, and the eaves portion 50 is clamped between the locking plate 47 and the leg 30, thereby fixing the main rod 1 to the eaves portion 50. The lower end of the lower sub-roof rod 2B is firmly fixed to the seams 37 by a clamping portion 12. Furthermore, Patent Document 2 discloses a scaffolding support column c in which a main rod 1 has a roof surface pressing section 26 with bifurcated legs 30 positioned below it, and an L-shaped locking plate 51, with its horizontal end bent upward toward the secondary rod side, is clamped and joined at the vertical side of the opening 17 of the clamping section 18 at the lower end, and in the scaffolding support column c, the locking plate 51 at the lower end of the main rod 1 is positioned similarly to the main support column b, at the eaves. The bent tip 49 of the main rod is brought into contact with the underside of the fascia board 48 so as to stand upright on the back surface of the fascia board 48, and the bifurcated leg 30 that straddles the vertical seams 37 of the roofing is pressed from the upper surface of the roofing surface, and the eaves portion 50 is clamped between the locking plate 51 and the leg 30, thereby fixing the main rod 1 to the eaves portion 50, and the lower end of the lower secondary rod 2B is firmly fixed to the seams 37 by the clamping portion 12.
[0006] However, in the scaffolding support columns for construction on roofs described in Patent Document 2, the lower end of the main rod 1 of scaffolding support column a is fixed to snow guards 38 and 42 which are fixed to standing seams 37 and flat seams 41 which are engagement parts with the roof surface, so it cannot be installed on roofs without snow guards 38 and 42g, and the locking plates 47 and 51 at the lower end of the main rod 1 are in contact with the lower surface of the fascia board 48 at the eaves, so it can only be installed on roofs with eaves. Furthermore, the scaffolding support column described in Patent Document 2 consists of a main rod 1 equipped with a clamping section 18 having a front clamping plate 19 and a rear clamping plate 20, and a secondary rod 2 equipped with an upper secondary rod 2A, a lower secondary rod 2B, a rotating rod 3, a screw shaft 4, a nut 5, connecting plates 6, 6, connecting plates 7, 7, a rotor 8, and a swinging plate 10 equipped with a clamping section 12. This structure has a large number of parts and is extremely complex, resulting in an expensive support column and the problem of requiring a great deal of effort to attach it to the roof. Furthermore, in the scaffolding support column of Patent Document 2, the main rod 1 is fixed at its lower end to a snow guard on the roof, and its upper end is fixed only to the upper end of a secondary rod 2, whose lower end is fixed to a standing seam on the roof. As a result, the lower end of the secondary rod 2 is prone to shifting relative to the roof and tilting from the angle at which the main rod 1 is installed. Structures such as safety fences constructed by installing multiple such scaffolding support columns are prone to deformation and have inferior strength.
[0007] Patent Document 3 (Japanese Patent Publication No. 2001-248299) describes a main rope support 2 made of a cylindrical member, a rectangular plate-shaped support base 3, mounting parts 4 provided at the four corners of the lower surface of the support base 3, a fixed support 6 made of a cylindrical member and provided to stand upright above the support base 3, a fall-holding support 7 provided spaced apart from the fixed support 6 and positioned upright above the support base 3, and a pair of first mounting pieces 8, 8 provided at the upper end of the fixed support 6 opposite to the support base 3 side. The disclosed rope attachment device 1 includes a rotating shaft 9 provided on the first mounting piece 8,8 and a rope attachment portion 10 provided at the tip of the rope support 2, and an upright holding portion 12 formed inside the hollow part of the fixed support 6 through which the rope support 2 can be inserted and which can hold the rope support 2 in an upright state, and the rope support 2 can be raised and lowered by moving it in a direction away from the support base 3 and then rotating it around the rotating shaft 9, so that when the rope support 2 is lowered it becomes the tip of the lowered holding support 7. However, in the rope attachment device 1 of Patent Document 3, the main rope support post 2 is held by the upright holding part 12 of the fixed support post 6 when it is standing upright, and its inclination angle cannot be arbitrarily adjusted so that it is perpendicular to the sloping roof or at a desired angle, which presents a problem in that it is not possible to form a framework for scaffolding or the like of various structures. Furthermore, in the rope attachment device 1 of Patent Document 3, the main rope support post 2 is erected on a rectangular, plate-shaped support base 3 whose four corners are attached to the seams of a roof or the like by attachment parts 4. Therefore, when installing the main rope support post 2, not only is space required to install the rectangular, plate-shaped support base 3, but there is also the problem that installation requires effort.

[Effects of the Invention]
[0018] In the roof pipe holder of the invention according to claim 1, since the pair of clamping plates are pressed against the side surface of the rib portion of the inclined surface of the metal roof by the clamping plate pressing member, without performing any processing on the metal roof or attaching installation members, the roof pipe holder can be installed at an arbitrary position with respect to the inclined surface to form various frameworks that are difficult to deform and have excellent strength. Since the pipe connection rotating member is rotatably held by the pair of clamping plates, a support column formed by the roof pipe holder can be installed at an arbitrary angle with respect to the inclined surface, and the support column can be installed on the inclined surface without requiring an installation space or labor, achieving the effect of being able to install the support column on the inclined surface.

In the diagram, 1A is a roof pipe holder, 2 is a left L-shaped plate, 2a is a base piece, 2b is an upright piece, 2h is a bolt hole, 3 is a right L-shaped plate, 3a is a base piece, 3b is an upright piece, 3h is a bolt hole, 4a and 4b are anti-rotation pieces, 5 is a retaining piece, 6 is a hexagonal bolt, 6a is the bolt head, 6b is the body, 7 is a nut, 8a and 8b are washers, 10 is a pipe connecting rotating member, 11 is a rotating plate, 11h is a bolt hole, 12 is a cylindrical body, 12h1 and 12h2 are circular holes, 13 is a locking pin, 13a is a spring plate, and 13b1 and 13b2 are projections. In each diagram, X is the left-right direction, Y is the front-back direction, and Z is the up-down direction (vertical direction). As shown in the figure, the roof pipe holder 1A includes a left L-shaped plate 2, a right L-shaped plate 3, a hexagonal bolt 6, a nut 7, and a pipe connecting rotating member 10.
[0028] The left L-shaped plate 2 and the right L-shaped plate 3 are a pair of clamping plates of the present invention, each formed by bending a single metal plate into an L-shape, and the left L-shaped plate 2 and the right L-shaped plate 3 are identical in shape and dimensions. The left L-shaped plate 2 and the right L-shaped plate 3 each consist of base pieces 2a and 3a, and upright pieces 2b and 3b that stand perpendicular to the base pieces 2a and 3a, respectively. Bolt holes 2h and 3h are provided at the center of the upright pieces 2b and 3b in the front-to-back direction (Y direction). Metal anti-rotation pieces 4a and 4b are attached to the front and back of the upright piece 2b of the left L-shaped plate 2, respectively, to restrict the rotation angle of the rotating plate 11 (described later) to within a certain range. The length from the anti-rotation pieces 4a and 4b to the center of the bolt hole 2h in the front-to-back direction is the same, and the height from the lower edge of the upright piece 2b on the upper surface of the anti-rotation pieces 4a and 4b is also the same. Furthermore, the length in the left-right direction (X direction) that the anti-rotation pieces 4a and 4b protrude from the upright piece 2b toward the upright piece 3b is greater than the distance between the upright pieces 2b and 3b when the roof pipe holder 1A is installed on a metal roof and the left L-shaped plate 2 (upright piece 2b) and the right L-shaped plate 3 (upright piece 3b) clamp the round seam (described later) of the metal roof. A convex-shaped retaining piece 5 is attached to the lower left side of the upright piece 3b of the right L-shaped plate 3 (the side facing the upright piece 2b), protruding towards the upright piece 2b and extending along the lower edge of the upright piece 3b. This retaining piece 5 serves to prevent the left L-shaped plate 2 and the right L-shaped plate 3 from detaching from the round seam of the metal roof when the roof pipe holder 1A is installed on the metal roof and the left L-shaped plate 2 and the right L-shaped plate 3 are clamped to the round seam of the metal roof (details will be described later). The retaining piece 5 may be attached to the right side of the upright piece 2b (the side facing the upright piece 3b), or it may be attached to both the lower right side of the upright piece 2b and the lower left side of the upright piece 3b.
[0029] The hexagonal bolt 6 and nut 7 constitute the clamping plate pressing member of the present invention. The hexagonal bolt 6 consists of a bolt head 6a and a body 6b. The body 6b is inserted through the bolt holes 2h, 11h, and 3h provided in the upright piece 2b, the rotating plate 11, and the upright piece 3b, respectively. The nut 7 is screwed onto the threaded portion of the body 6b that protrudes from the bolt hole 3h of the upright piece 3b. In this case, the washer 8a is inserted through the body portion 6b between the upright piece 2b and the rotating plate 11, and the washer 8b is inserted through the body portion 6b between the rotating plate 11 and the upright piece 3b. As a result, the left L-shaped plate 2 and the right L-shaped plate 3 are sandwiched between the bolt head 6a and the body 6b, and the rotating plate 11 is held rotatably on the body 6b by being sandwiched between the left L-shaped plate 2 and the right L-shaped plate 3 via washers 8a and 8b. The anti-rotation pieces 4a and 4b may be formed by making a convex shape on a portion of the front and back surfaces of the upright piece 2b of the metal plate forming the left L-shaped plate 2, and then bending this convex shape at a right angle. Alternatively, the hexagonal bolt 6 may be inserted from the right L-shaped plate 3 side, with the bolt head 6a positioned on the right side of the right L-shaped plate 3 and the nut 7 positioned on the left side of the left L-shaped plate 2. Furthermore, bolt holes 2h and 3h may be made square in shape, and instead of hexagonal bolts 6, square-headed round-head bolts (bolts with a rounded head and a square prism-shaped underside) with a shank that matches the square shape of bolt holes 2h and 3h may be used.
[0030] The pipe connecting rotating member 10 comprises a rotating plate 11 and a cylindrical body 12. The rotating plate 11 is a rectangular metal plate in side view. A bolt hole 11h is provided at the center of the lower part of the rotating plate 11 in the front-rear direction. As described above, the body portion 6b is inserted through the bolt hole 11h while sandwiched between the left L-shaped plate 2 and the right L-shaped plate 3, and is rotatably held by the hexagonal bolt 6. The cylindrical body 12 is the pipe connection part of the present invention, and is made of a circular metal pipe, with its lower end joined to the upper surface of the rotating plate 11 by welding or the like, so that it rotates together with the rotating plate 11. Two circular holes 12h1 and 12h2 are provided opposite each other in the center of the cylindrical body 12 in the vertical direction (Z direction). The lock pin 13 consists of a trapezoidal metal spring plate 13a in side view, with V-shaped projections 13b1 and 13b2 formed at both ends of the spring plate 13a. The two ends of the spring plate 13a of the lock pin 13 are brought closer together by a force acting in the closing direction, and the distance between the spring plate 13a when no force is acting on both ends is greater than the inner diameter of the cylindrical body 12. The lock pin 13 is inserted into the inside of the cylindrical body 12 from the top side with both ends of the spring plate 13a approaching and biased, and the projections 13b1 and 13b2 are fitted into the circular holes 12h1 and 12h2 and protrude outwards, so that the lock pin 13 is attached to the upper inside of the cylindrical body 12. This locking pin 13 connects the vertical pipe, which is fitted onto the outer surface of the cylindrical body 12, to the cylindrical body 12 (details will be described later).
[0031] Figure 5 is an explanatory diagram illustrating the rotation angle range of the pipe connection rotating member 10 in the roof pipe holder 1A. Figure (a) is a left side view of the roof pipe holder 1A when the pipe connection rotating member 10 is not tilted, Figure (b) is a left side view of the roof pipe holder 1A when the pipe connection rotating member 10 is tilted furthest to the rear, and Figure (c) is a left side view of the roof pipe holder 1A when the pipe connection rotating member 10 is tilted furthest to the front. In the diagram, VL is the vertical line passing through the rotation center of the pipe connecting rotating member 10, and PL is the axis of the cylindrical body 12. In the pipe connecting rotating member 10, the rotating plate 11, through which the body 6b of the hexagonal bolt 6 is inserted into the bolt hole 11h, rotates around the axis of the body 6b, and the cylindrical body 12 fixed to the upper surface of the rotating plate 11 rotates together with the rotating plate 11 and tilts in the Y direction (front-back direction). When the cylindrical body 12 is not tilted, the vertical line VL and the axis PL coincide, as shown in Figure 5(a). In contrast, when the rotating plate 11 rotates so that the cylindrical body 12 tilts inward, the back surface of the rotating plate 11 comes into contact with the anti-rotation piece 4b, as shown in Figure 5(b), and the rotation of the rotating plate 11 is restricted. Furthermore, when the rotating plate 11 rotates so that the cylindrical body 12 tilts toward the front, the front surface of the rotating plate 11 comes into contact with the anti-rotation piece 4a, as shown in Figure 5(c), and the rotation of the rotating plate 11 is restricted.
[0032] In this case, the distance in the Y direction from the front and back axis PL of the rotating plate 11 is the same, the distance in the Y direction from the vertical line VL of the anti-rotation pieces 4a and 4b is the same, and the height (position in the Z direction) of the upper surfaces of the anti-rotation pieces 4a and 4b is the same. From this point onward, when the front and back surfaces of the rotating plate 11 come into contact with the anti-rotation pieces 4a and 4b, the angle between the axis PL and the vertical line VL is the same. This becomes the maximum value φmax of the angle φ between the axis PL and the vertical line VL, and the rotation angle range of the pipe connecting rotating member 10 is 0 to φmax. φmax is determined by the length of the rotating plate 11 in the Y direction at φ=0, the distance in the Y direction from the anti-rotation piece 4a(4b) to the vertical line VL, and the height of the upper surface of the anti-rotation piece 4a(4b). However, φmax is set according to the slope range of the metal roof on which the roof pipe holder 1A is installed. For example, if the slope range of the metal roof on which the roof pipe holder 1A is installed is from 3-inch slope (16.7 degrees) to 6-inch slope (31.0 degrees), the φmax will be set to approximately 35 degrees. If the roof pipe holder 1A is also installed on a steep metal roof with a slope of 7-inch slope (35.0 degrees) to 9-inch slope (42.0 degrees), the φmax will be set to approximately 45 degrees. By making φmax slightly larger than the maximum slope θmax of the metal roof on which the roof pipe holder 1A is installed (for example, about 5-20% of θmax) (so that φmax is 105-120% or less of θmax), the pipe connection rotating member 10 can be positioned vertically when the roof pipe holder 1A is installed on the metal roof, and the pipe connection rotating member 10 cannot be rotated more than necessary, thereby improving the convenience of handling and workability during storage, transportation, and installation of the roof pipe holder 1A.
[0033] [Roof support posts] Figure 6 is a perspective view of a roof support using the roof pipe holder shown in Figure 1 installed on the inclined surface of a corrugated metal roof; Figure 7(a) is a front view of the roof support shown in Figure 6; Figure 7(b) is a left side view of the roof support shown in Figure 6; Figure 8(a) is a cross-sectional view of section CC of Figure 7(a); Figure 8(b) is a cross-sectional view of section DD of Figure 7(b); and Figure 9 is an enlarged cross-sectional view of section EE of Figure 7(b). In the diagrams, 1P is a roof support, 14 is a vertical pipe, 14h1 and 14h2 are connection holes, 15 is a corrugated metal roof, 16 is an inclined surface, 16a and 16b are valleys, 17 is a peak, 18 is a rounded seam, 18a is a bulge, and 18b is a neck. In each diagram, X is the left-right direction, Y is the front-back direction, Z is the up-down direction (vertical direction), Sh is the inclination direction of the inclined surface of the corrugated metal roof, and Sv is perpendicular to the inclined surface of the corrugated metal roof. The same reference numerals are used for elements that are the same as those shown in Figures 1 to 4. As shown in the figure, the roof support column 1P is equipped with a roof pipe holder 1A and a vertical pipe 14, and is installed on the inclined surface 16 of the corrugated metal roof 15. The vertical pipe 14 is made of a circular metal pipe, and its inner diameter is slightly larger than the outer diameter of the cylindrical body 12. Two connection holes 14h1 and 14h2 are provided opposite each other at the lower part of the vertical pipe 14. The corrugated metal roof 15 is a metal roof of the seam-fastened type made by joining steel plates together and bending them into a corrugated (uneven) shape. Its sloping roof surface, the inclined surface 16, is tilted at an angle θ with respect to the horizontal plane, and consists of a series of flat valleys and trapezoidal peaks (the figure shows the valleys 16a, 16b and the peak 17, which are parts of this). On the upper surface of the peak 17, round seams 18 are formed by bending and joining the joints of the steel plates. The rounded seam 18 is the protruding ridge portion of the present invention, and extends in the inclination direction Sh, having a bulging portion 18a and a neck portion 18b that protrude and curve in both left and right directions. The bulging portion 18a has a cross-section perpendicular to the inclination direction Sh that is close to an oval or ellipse shape, and the neck portion 18b is continuous with the bulging portion 18a below and rises from the upper surface of the peak portion 17. In the roof support column 1P, the base pieces 2a and 3a of the roof pipe holder 1A are placed on the upper surface of the ridge portion 17, and the left L-shaped plate 2 and the right L-shaped plate 3 are installed on the ridge portion 17 of the inclined surface 16 by sandwiching the bulging portion 18a of the round seam 18 with the upright pieces 2b and 3b. In the roof pipe holder 1A, the body 6b of the hexagonal bolt 6 is inserted through the bolt holes 2h, 11h, and 3h provided in the upright piece 2b, the rotating plate 11, and the upright piece 3b, with washers 8a and 8b interposed between them, and a nut 7 is screwed onto the threaded portion of the body 6b. Then, by tightening the nut 7, the upright pieces 2b and 3b press against the bulging portion 18a, and the roof pipe holder 1A is fixed to the inclined surface 16 (the upper surface of the peak portion 17). In this way, the vertical pipe 14 is connected to the cylindrical body 12 in the roof pipe holder 1A installed on the inclined surface 16. Specifically, the vertical pipe 14 is placed over the cylindrical body 12, the connecting holes 14h1 and 14h2 of the vertical pipe 14 are aligned with the protruding pieces 13b1 and 13b2 of the lock pin 13 that protrude from the circular holes 12h1 and 12h2 of the cylindrical body 12, and the tips of the connecting holes 14h1 and 14h2 protrude from the connecting holes 14h1 and 14h2, thereby connecting the vertical pipe 14 to the cylindrical body 12. Furthermore, the protruding portion of the present invention is not limited to a rounded fastener, but may also be a square fastener having a protruding portion in either the left or right direction, with a curved bulge on the non-protruding side and the same neck portion as a rounded fastener, or a square fastener having a protruding portion in either the left or right direction, with a flat bulge on the non-protruding side and the same neck portion as a rounded fastener.
[0034] Figure 10 is an explanatory diagram illustrating the rotation angle range of the vertical pipe 14 (pipe connecting rotating member 10) of the roof support column 1P. Figure (a) is a left side view of the roof support column 1P in the state where the vertical pipe 14 (pipe connecting rotating member 10) is tilted furthest to the rear, and Figure (c) is a left side view of the roof support column 1P in the state where the vertical pipe 14 (pipe connecting rotating member 10) is tilted furthest to the front. In the figure, PL' is the axis of the vertical pipe 14, and SvL is a vertical line that passes through the rotation center of the vertical pipe 14 (pipe connecting rotating member 10) and is perpendicular to the upper surface (inclined surface 16) of the peak 17. In the roof support column 1P, the rotating plate 11 of the pipe connecting rotating member 10 is rotatably held by the body 6b of the hexagonal bolt 6, and the vertical pipe 14 fixed to the pipe connecting rotating member 10 rotates together with the rotating plate 11 and tilts in the Y direction (front-back direction). In this case, as shown in Figure 10(a), the vertical pipe 14 can be tilted inward until the back surface of the rotating plate 11 hits the anti-rotation piece 4b, and the angle between the axis PL' and the vertical line SvL at that time is φmax. Furthermore, as shown in Figure 10(b), the vertical pipe 14 can be tilted forward until the front surface of the rotating plate 11 hits the anti-rotation piece 4a, and at that time the angle between the axis PL' and the vertical line SvL is φmax. Therefore, the vertical pipe 14 can be tilted within an angular range of 0 to ±φmax with respect to the vertical line SvL (vertical direction Sv). Furthermore, since the inclination angle of the inclined surface 16 is θ, and the angle between the vertical line VL and the perpendicular line SvL is also θ, and 0 < θ < φmax, the vertical pipe 14 can be made to stand upright and face the vertical direction (Z direction). Furthermore, in the roof pipe holder 1A, a retaining piece 5 is attached to the lower part of the left side surface (the surface facing the upright piece 2b) of the upright piece 3b. When a force acts to tilt or lift the vertical pipe 14, and the left L-shaped plate 2 and the right L-shaped plate 3 move away from the upper surface of the ridge 17 in the roof pipe holder 1A, the retaining piece 5 comes into contact with the lower surface of the bulge 18a of the round seam 18. In other words, the retaining piece 5 catches on the bulge 18a, preventing the left L-shaped plate 2 and the right L-shaped plate 3 from coming off the round seam 18. Furthermore, when the roof pipe holder 1A is installed on the sloping surface of a corrugated metal roof that has square or angular seams instead of round seams, the left L-shaped plate 2 and the right L-shaped plate 3 are installed on the peak of the sloping surface so that the retaining piece 5 is positioned on the side where the bulging part of the square or angular seam protrudes. Furthermore, if the retaining pieces 5 are attached to both the lower right side of the upright piece 2b and the lower left side of the upright piece 3b, the left L-shaped plate 2 and the right L-shaped plate 3 are further prevented from coming off the round seam 18. moreover
[0035] As described above, the roof support column 1P is equipped with a roof pipe holder 1A and a vertical pipe 14. The roof pipe holder 1A is equipped with a left L-shaped plate 2, a right L-shaped plate 3, a hexagonal bolt 6, a nut 7, and a pipe connecting rotating member 10. The pipe connecting rotating member 10 is equipped with a rotating plate 11 and a cylindrical body 12. The hexagonal bolt 6 is inserted through the left L-shaped plate 2, the rotating plate 11, and the right L-shaped plate 3, and the nut 7 is screwed onto the hexagonal bolt 6. The vertical pipe 14 is connected to the cylindrical body 12. This allows for a simple structure for the roof pipe holder 1A and the roof support column 1P. When installing the roof support column 1P on the inclined surface 16 of the corrugated metal roof 15, the left L-shaped plate and the right L-shaped plate 3 are attached to the inclined surface 1 By placing the round seam 18 on the upper surface of the ridge 17 of the 6 and tightening the nut 7 screwed onto the hexagonal bolt 6, the roof pipe holder 1A can be fixed to the upper surface of the ridge 17 of the inclined surface 16. This allows for the installation of roof support columns 1P at any position on any ridge 17 of the inclined surface 16 without processing the corrugated metal roof 15 or attaching any installation components, thereby forming various frameworks that are less prone to deformation and have superior strength. Furthermore, since the rotating plate 11 of the pipe connecting rotating member 10 is rotatably held by the hexagonal bolt 6, the vertical pipe 14 of the roof support column 1P can be set to any angle with respect to the inclined surface 16.
[0036] [Other examples of roof pipe holders] In the roof pipe holder of the present invention, various members other than the cylindrical body 12 can be used as the pipe connection portion of the pipe connection rotating member. Figure 11 is a perspective view of a roof pipe holder using a jack as the pipe connection part, Figure 12(a) is a left side view of the roof pipe holder shown in Figure 11, and Figure 12(b) is a front view of the roof pipe holder shown in Figure 11. In the figures, 1B is a roof pipe holder, 20 is a pipe connecting rotating member, 21 is a rotating plate, 21t is a connecting projection, 22 is a jack, 22a is a threaded rod, and 22b is a handle. Components identical to those of the roof pipe holder 1A shown in Figures 1 to 4 are denoted by the same reference numerals. Roof pipe holder 1B is the same as roof pipe holder 1A in that it includes a left L-shaped plate 2, a right L-shaped plate 3, anti-rotation pieces 4a and 4b, anti-detachment piece 5, a hexagonal bolt 6, a nut 7, and washers 8a and 8b, but differs from roof pipe holder 1A in that it includes a pipe connecting rotating member 20 instead of a pipe connecting rotating member 10. The pipe connecting rotating member 20 includes a rotating plate 21 and a jack 22. The rotating plate 21 differs from the rotating plate 11 of the pipe connecting rotating member 10 in that it has a connecting projection 21t that is convex in side view on its upper part, but its other shapes and structures are the same as those of the rotating plate 11. In other words, a bolt hole identical to the bolt hole 11h is provided at the center of the lower part of the rotating plate 21 in the front-rear direction, and the body 6b of the hexagonal bolt 6 is inserted through this bolt hole while sandwiched between the left L-shaped plate 2 and the right L-shaped plate 3, so that the rotating plate 21 is rotatably held by the hexagonal bolt 6 in the same way as the rotating plate 11. The jack 22 comprises a metal threaded rod 22a and a handle 22b. The handle 22b consists of a rotating cylinder and a pair of horizontal bars. The rotating cylinder has a female thread that engages with a male thread formed on the circumferential surface of the threaded rod 22a. By rotating the handle 22b, the handle 22b moves in the axial direction (Z direction) of the threaded rod 22a. The lower end (bottom surface) of the threaded rod 22a of the jack 22 is joined to the upper surface of the connecting projection 21t of the rotating plate 21 by welding or the like, thereby holding the jack 22 to the rotating plate 21 and rotating together with the rotating plate 21.
[0037] The roof pipe holder 1B is installed on the sloping surface of the corrugated metal roof in the same manner as the roof pipe holder 1A. In the roof pipe holder 1B installed on the sloping surface of the corrugated metal roof, a vertical jack pipe having an inner diameter slightly larger than the outer diameter of the threaded rod 22a is fitted over (sewn onto) the threaded rod 22a of the jack 22, and the lower surface of the vertical jack pipe rests on the upper surface of the rotating cylinder of the handle 22b. In this roof pipe holder 1B, similar to the rotating plate 11 of the roof pipe holder 1A, the rotating plate 21 is rotatably held on the body 6b of the hexagonal bolt 6 and can be tilted within an angular range of 0 to ±φmax with respect to the vertical direction Sv. Furthermore, since the inclination angle θ of the inclined surface on which the roof pipe holder 1B is installed is 0 < θ < φmax, the threaded rod 22a of the jack 22 of the pipe connecting rotating member 20 can be made to stand vertically, so that the vertical pipe for the jack faces the vertical direction (Z direction). In this case, unlike the vertical pipe 14 connected to the cylindrical body 12 of the roof pipe holder 1A, the roof pipe holder 1B allows for height adjustment of the vertical pipe for the jack attached to the jack 22. In other words, by rotating the handle 22b of the jack 22, the handle 22b moves in the axial direction (Z direction) of the threaded rod 22a, and as a result, the vertical pipe for the jack also moves in the axial direction (Z direction) of the threaded rod 22a, allowing the height of the vertical pipe for the jack to be adjusted.
[0038] Figure 13(a) is a perspective view of a roof pipe holder using a pipe clamp as the pipe connection part, Figure 13(b) is a left side view of the roof pipe holder shown in Figure 13(a), and Figure 13(c) is a front view of the roof pipe holder shown in Figure 13(a). In the figures, 1C is a roof pipe holder, 30 is a pipe connecting rotating member, 31 is a rotating plate, 31t is a connecting projection, 32 is a pipe clamp, 32a is a lower clamp piece, 32b is an upper clamp piece, 32c is a hinge pin, 32d is a support pin, 32e is a rod, and 32f is a nut. Components identical to those of the roof pipe holder 1A shown in Figures 1 to 4 are denoted by the same reference numerals. Roof pipe holder 1C is the same as roof pipe holders 1A and 1B in that it includes a left L-shaped plate 2, a right L-shaped plate 3, anti-rotation pieces 4a and 4b, anti-detachment piece 5, a hexagonal bolt 6, a nut 7, and washers 8a and 8b, but it differs from roof pipe holders 1A and 1B in that it has a pipe connecting rotating member 30 instead of pipe connecting rotating members 10 and 20. The pipe connecting rotating member 30 includes a rotating plate 31 and a pipe clamp 32. The rotating plate 31 is the same as the rotating plate 21 of the roof pipe holder 1B. In other words, the rotating plate 31 has a connecting projection 31t that is convex in side view on its upper part, and a bolt hole the same as the bolt hole 11h is provided at the center position in the front-rear direction on the lower part of the rotating plate 31, and the body 6b of the hexagonal bolt 6 is inserted through this bolt hole while sandwiched between the left L-shaped plate 2 and the right L-shaped plate 3, and the rotating plate 31 is held rotatably by the hexagonal bolt 6 in the same way as the rotating plates 11 and 21. The pipe clamp 32 comprises a metal lower clamp piece 32a, an upper clamp piece 32b, a hinge pin 32c, a support pin 32d, a rod 32e, and a nut 32f. In this pipe clamp 32, the lower clamp piece 32a and the upper clamp piece 32b have curved portions that contact the round pipe that the pipe clamp 32 grips, and their right ends are connected by a hinge pin 32c, allowing them to open and close in the vertical direction. Furthermore, in the lower clamp piece 32a, a support pin 32d to which a rod 32e is attached is mounted on its left end, and a threaded portion is formed on the tip side of the rod 32e, to which a nut 18f is screwed. Furthermore, the left end of the upper clamp piece 32b is provided with a U-shaped notch that allows the upper threaded portion of the rod 32e to protrude from the upper surface of the upper clamp piece 32b. The lower clamp piece 32a of the pipe clamp 32 has its center in the X direction on the lower side surface joined to the upper surface of the connecting projection 31t of the rotating plate 31 by welding or the like. As a result, it is held by the rotating plate 31 by welding or the like and rotates together with the rotating plate 31.
[0039] Roof pipe holder 1C is installed on the sloping surface of the corrugated metal roof in the same manner as roof pipe holders 1A and 1B. In the roof pipe holder 1C installed on the sloping surface of a corrugated metal roof, a round pipe made of a circular metal pipe is held by the pipe clamp 32. Specifically, the left side of the upper clamp piece 32b is lifted and opened, the rod 32e is tilted to the left, the circumferential surface of the round pipe is clamped between the lower clamp piece 32a and the upper clamp piece 32b, the rod 32e is raised so that its upper threaded portion protrudes upward from the U-shaped notch of the upper clamp piece 32b, the nut 32f is screwed onto the threaded portion of the rod 32e and tightened, the curved portions of the lower clamp piece 32a and the upper clamp piece 32b are brought into contact with the circumferential surface of the round pipe, thereby fixing and holding the round pipe in place with the pipe clamp 32. Figure 14 is an explanatory diagram illustrating the usage state of a roof pipe holder 1C installed on the inclined surface 16 of a corrugated metal roof 15. Figure (a) is a left side view of the roof pipe holder 1C holding a round pipe parallel to the inclined surface 16, and Figure (b) is a left side view of the roof pipe holder 1C holding a round pipe horizontally. In the figures, 33 is the round pipe, and PL'' is the axis of the round pipe 33. In the roof pipe holder 1C installed on the inclined surface 16, the rotating plate 31 of the pipe connecting rotating member 30 is rotatably held on the body 6b of the hexagonal bolt 6, and the round pipe 33 held by the pipe clamp 32 fixed to the rotating plate 31 rotates together with the rotating plate 31 and tilts in the Y direction (front-back direction). In this case, as shown in Figure 14(a), by not tilting the round pipe 33 and keeping the axis PL'' perpendicular to the vertical line SvL, the axis PL'' faces the inclination direction Sh, making the round pipe 33 parallel to the inclined surface 16, and the round pipe 33 becomes an inclined pipe that is inclined with respect to the horizontal plane. Furthermore, as shown in Figure 14(b), if the round pipe 33 is tilted inward by the inclination angle θ of the inclined surface 16, the axis PL'' will point in the Y direction, making the round pipe 33 horizontal, and thus the round pipe 33 becomes a horizontal pipe. Figure 15 is a left side view of the round pipe 33 (pipe connecting rotating member 30) held by the roof pipe holder 1C installed on the inclined surface 16, in its furthest inclined position. In the figure, PLv is the longitudinal axis of the pipe connecting rotating member 30, perpendicular to the axis PL''. As shown in Figure 15, when the round pipe 33 (pipe connecting rotating member 30) is tilted to its furthest back position, the angle between the axis PLv and the vertical line SvL becomes φmax. Therefore, the round pipe 33 can be tilted to an angle of φmax with respect to the inclined surface 16, and the round pipe 33 becomes an inclined pipe.
[0040] [Scaffolding for roofs] Figure 16 is a perspective view of a portion of the roof scaffolding using roof support column 1P as shown in Figure 6, etc., Figure 17 is a front view of the roof scaffolding shown in Figure 16, and Figure 18 is a left side view of the roof scaffolding shown in Figure 16. In the diagram, 1Q, 1R, and 1S are roof supports; 14P, 14Q, 14R, and 14S are vertical pipes; 16c is a valley section; 17' is a peak section; 18' is a rounded seam; 18a' is a bulge section; 18b' is a neck section; 40 is roof scaffolding; and 41, 42, 43, and 44 are horizontal pipes. Components identical to those shown in Figures 6 to 9 are denoted by the same reference numerals. The roof scaffolding 40 is equipped with roof support columns 1P, 1Q, 1R, and 1S, and horizontal pipes 41, 42, 43, and 44, and is installed on the inclined surface 16 of the corrugated metal roof 15. On the inclined surface 16, a valley 16b is followed by a peak 17' and another valley 16c in the X direction (to the right), and a rounded seam 18' having a bulge 18a' and a neck 18b' is formed on the peak 17'. Roof support posts 1Q, 1R, and 1S are the same as roof support post 1P and are equipped with a roof pipe holder 1A and a vertical pipe 14. Here, in order to identify the vertical pipes 14 of each roof support column, the vertical pipes 14 of roof supports 1P, 1Q, 1R, and 1S are designated as vertical pipes 14P, 14Q, 14R, and 14S, respectively. As shown in Figure 16, the roof pipe holder 1A of the roof support column 1P is installed on the front upper side of the ridge portion 17 by sandwiching the round seam 18 (bulging portion 18a) between the left L-shaped plate 2 and the right L-shaped plate 3 (upright pieces 2b, 3b). The roof pipe holder 1A of the roof support column 1Q is installed on the upper rear side of the ridge portion 17 by sandwiching the round seam 18 (bulging portion 18a) between the left L-shaped plate 2 and the right L-shaped plate 3 (upright pieces 2b, 3b). The roof pipe holder 1A of the roof support column 1R is installed on the front upper surface of the ridge portion 17' by sandwiching the round seam 18' (bulging portion 18a') between the left L-shaped plate 2 and the right L-shaped plate 3 (upright pieces 2b, 3b). The roof pipe holder 1A of the roof support column 1S is installed on the upper rear side of the peak 17' by sandwiching the round seam 18' (bulging part 18a') between the left L-shaped plate 2 and the right L-shaped plate 3 (upright pieces 2b, 3b). The vertical pipes 14P, 14Q, 14R, and 14S are connected to the cylindrical body 12 of the pipe connecting rotating member 10 of each roof pipe holder 1A of the roof support columns 1P, 1Q, 1R, and 1S. In this case, each vertical pipe 14P, 14Q, 14R, and 14S is positioned upright and facing the vertical direction (Z direction).
[0041] In this way, horizontal pipes 41, 42, 43, and 44, which are made of circular metal pipes, are attached to the roof supports 1P, 1Q, 1R, and 1S. Specifically, horizontal pipe 41 is attached to vertical pipes 14P and 14Q at both ends via pipe clamps (not shown), horizontal pipe 42 is attached to vertical pipes 14P and 14R at both ends via pipe clamps (not shown), horizontal pipe 43 is attached to vertical pipes 14R and 14S at both ends via pipe clamps (not shown), and horizontal pipe 44 is attached to vertical pipes 14Q and 14S at both ends via pipe clamps (not shown). In this case, opposing horizontal pipes 41 and 43 are the same length and are installed at the same horizontal height, and opposing horizontal pipes 42 and 44 are also the same length (same or different length as horizontal pipes 41 and 43) and are installed slightly offset from horizontal pipes 41 and 43 so that they are at the same horizontal height. Furthermore, on the inclined surface 16 of the corrugated metal roof 15, roof supports identical to roof support 1P are installed on the upper surface of the peaks in the left, right, front, and rear directions of roof supports 1P, 1Q, 1R, and 1S as needed, and horizontal pipes identical to horizontal pipes 41 and 42 are attached between adjacent roof supports. Furthermore, in the vertical direction of the roof support columns 1P, 1Q, 1R, 1S, etc., additional horizontal pipes can be attached above the horizontal pipes 41, 42, 43, 44, etc., as needed, forming two or more levels of horizontal pipes. In this way, a roof scaffolding 40 is installed on the front or part of the inclined surface 16 of the corrugated metal roof 15, consisting of multiple roof support columns 1P, 1Q, 1R, 1S, etc., oriented vertically, and one or more rows of horizontally oriented horizontal pipes 41, 42, 43, 44, etc., attached between adjacent roof support columns.
[0042] [Roof safety fence] Figure 19 is a perspective view of a part of a roof safety fence using roof support posts as shown in Figure 6, etc., Figure 20 is a front view of the roof safety fence shown in Figure 19, and Figure 21 is a left side view of the roof safety fence shown in Figure 19. In the figures, 1A' is the first roof pipe holder, 1A'' is the second roof pipe holder, 1T and 1T' are the first roof support columns, 1U and 1U' are the second roof support columns, 14T and 14T' are the first vertical pipes, 14U and 14U' are the second vertical pipes, 50 is the roof safety fence, 51 and 51' are the unit frames, 52 and 52' are the base pipes, 53 and 53' are the hypotenuse pipes, and 54 and 55 are the support column connecting pipes. The same reference numerals are used for parts that are the same as those shown in Figures 6 to 9 and Figures 16 to 18. The roof safety fence 50 comprises unit frames 51, 51' and support connecting pipes 54, 55, and is installed on the inclined surface 16 of the corrugated metal roof 15. The unit frame 51 includes a first roof support column 1T, a second roof support column 1U, a base pipe 52 and a hypotenuse pipe 53 made of circular metal pipes. The first roof support column 1T has the same configuration as the roof support column 1P shown in Figure 6, and is equipped with a first roof pipe holder 1A' and a first vertical pipe 14T. The first roof pipe holder 1A' is the same as the roof pipe holder 1A, and the first vertical pipe 14T is a shortened version of the vertical pipe 14. The second roof support column 1U has the same configuration as the roof support column 1P, and is equipped with a second roof pipe holder 1A'' and a second vertical pipe 14U. The second roof pipe holder 1A'' is the same as the roof pipe holders 1A and 1A', and the second vertical pipe 14U is a vertical pipe 14 that is longer than the first vertical pipe 14T. The axial length of the second vertical pipe 14U is 2 to 15 times the axial length of the first vertical pipe 14T.
[0043] In the unit frame 51, the first roof pipe holder 1A' and the second roof pipe holder 1A'' are installed on the front and back sides of the upper surface of the peak 17 of the inclined surface 16, in the same manner as the roof pipe holder 1A of the roof support column 1P. Then, so that the base pipe 52 is positioned horizontally, one end of the base pipe 52 (the front end) is attached to the first vertical pipe 14T via a pipe clamp (not shown), and the other end of the base pipe 52 (the rear end) is attached to the bottom of the second vertical pipe 14U via a pipe clamp (not shown). Furthermore, so that the hypotenuse pipe 53 is positioned in a direction inclined with respect to the horizontal plane, one end of the hypotenuse pipe 53 (the front end) is attached to the first vertical pipe 14T via a pipe clamp (not shown), and the other end of the hypotenuse pipe 53 (the rear end) is attached to the top of the second vertical pipe 14U via a pipe clamp (not shown). In this case, one end of the base pipe 52 is behind the first vertical pipe 14T, and one end of the hypotenuse pipe 53 is to the left of the first vertical pipe 14T, and the positions of one end of both pipes in the Z direction are approximately the same. Furthermore, the other end of the base pipe 52 is in front of the second vertical pipe 14U, the other end of the hypotenuse pipe 53 is to the left of the second vertical pipe 14U, the position of the other end of the hypotenuse pipe 53 in the Z direction is above the position of the other end of the base pipe 52 in the Z direction, and the distance in the Z direction between the other ends of both pipes is 1 to 2.5 times the length of the base pipe 52. As a result, the unit frame 51 forms a frame that is approximately a right triangle.
[0044] The unit frame 51' is the same as the unit frame 51 and includes a first roof support 1T', a second roof support 1U', a base pipe 52', and a hypotenuse pipe 53'. In other words, the first roof support column 1T' is the same as the first roof support column 1T of the unit frame 51, and is equipped with a first roof pipe holder 1A' and a first vertical pipe 14T', and the first vertical pipe 14T' is the same as the first vertical pipe 14T. The second roof support column 1U' is the same as the second roof support column 1U of the unit frame 51, and is equipped with a second roof pipe holder 1A'' and a second vertical pipe 14U', the second vertical pipe 14U' is the same as the second vertical pipe 14U. In the unit frame 51', the first roof pipe holder 1A' and the second roof pipe holder 1A'' are installed on the front and back sides of the upper surface of the peak 17' of the inclined surface 16, in the same manner as the roof pipe holder 1A of the roof support column 1P. Furthermore, the base pipe 52' and the hypotenuse pipe 53' are the same as the base pipe 52 and hypotenuse pipe 53 of the unit frame 51, respectively, and the base pipe 52' and hypotenuse pipe 53' are attached to the first vertical pipe 14T' and the second vertical pipe 14U' in the same way that the base pipe 52 and the hypotenuse pipe 53 are attached to the first vertical pipe 14T' and the second vertical pipe 14U'.
[0045] The support connecting pipes 54 and 55 are made of long, circular metal pipes and are attached to the second roof support columns 1U and 1U' of the unit frames 51 and 51', connecting the unit frames 51 and 51'. Specifically, the upper support connecting pipe 54 is attached to the second vertical pipes 14U and 14U' via pipe clamps (not shown) at a position slightly above where the hypotenuse pipes 53 and 53' are attached behind the second vertical pipes 14U and 14U'. Furthermore, the lower support connecting pipe 55 is attached to the second vertical pipes 14U and 14U' via pipe clamps (not shown) at an intermediate position between the positions where the rear base pipe 52 and the hypotenuse pipe 53 are attached to the second vertical pipe 14U, and at an intermediate position between the positions where the rear base pipe 52' and the hypotenuse pipe 53' are attached to the second vertical pipe 14U'. In this way, a part of the roof safety fence 50 is formed, with the unit frames 51 and 51' connected to the support connecting pipes 54 and 55. Then, on the inclined surface 16 of the corrugated metal roof 15, if necessary, the same unit frames as unit frames 51 and 51' are installed at predetermined intervals on the left side in the X direction of unit frame 51 and on the left side in the X direction of unit frame 51', and support connecting pipes 54 and 55 are attached to the second roof support columns (second vertical pipes) of these unit frames, thereby forming a roof safety fence 50 in which the unit frames 51 and 51' and one or more unit frames installed on both their left and right sides are connected by the support connecting pipes 54 and 55. In this way, a net is attached to the entire perimeter or part of the roof safety fence 50 installed on the sloping surface 16 of the corrugated metal roof 15 to prevent workers, materials, etc. from falling.
