Description

The present invention relates to a roof installation tool and a roof structure using the roof installation tool.

Traditionally, scaffolding has often been set up during construction work. Setting up scaffolding makes it possible to work at heights. However, construction work cannot be carried out in rainy weather, and construction schedules may be delayed. Delays in construction schedules can lead to a deterioration of the working environment. For this reason, there is a need to take measures to allow construction work to be carried out even in rainy weather.

The following Patent Document 1 describes setting up a roof on scaffolding. In this patent document, legs are placed on the roof of a building, and the legs are attached to the tops of the pipes that make up the scaffolding, and the tent is supported by the legs. However, it is difficult to place the legs on the roof of a building.

In the below-mentioned Patent Document 2, tension ropes and position adjustment ropes are attached to the posts, and the sheet is stretched over the roof. It is difficult to support a sheet large enough to cover the roof with ropes.

[Embodiment 1]
The roof installation tool 10 shown in Figures 1, 2, and 3 is a metal fitting for installing roof components on or near the top of a support 12. Attaching the roof components to the roof installation tool 10 results in a roof structure 14 shown in Figure 4.

The posts 12 are cylinders or rods that are erected vertically relative to the ground or the like. For example, the posts 12 may be scaffolding posts 12 that are set up around a building 16 at a construction site or the like. In the case of scaffolding posts 12, the spacing between the posts 12 is constant. The cross section of the posts 12 is circular. By attaching the roof installation tool 10 to the scaffolding posts 12 and then attaching the members that make up the roof, a roof structure 14 can be provided on the scaffolding (Figure 4). The roof structure 14 on the scaffolding functions as a rain shelter, a shading shelter, or both.

The roof installation tool 10 has a pole-side joint 18 that is attached to the top of the pole 12 and a roof-side joint 20 that is inclined relative to the pole 12.

The pillar-side joint 18 is a cylinder made of metal. The length of this cylinder coincides with the length of the pillar 12. The upper part 22 of the pillar 12 is inserted into the pillar-side joint 18. A hole 24 is drilled in the upper part 22 of the pillar 12. A hole 26 is also provided in the pillar-side joint 18, and the hole 24 of the pillar 12 coincides with the hole 26 of the pillar-side joint 18. A bolt or pin may be passed through the hole 24 of the pillar 12 and the hole 26 of the pillar-side joint 18 to fix the pillar-side joint 18 to the pillar 12. In the case of a bolt, a nut may be used to prevent the bolt from slipping out of the holes 24 and 26.

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 direction of the support 12 and the support side joint 18. A sheet holding member 28 is attached to the roof side joint 20. In FIG. 1, one end 30 of the sheet holding member 26 is inserted into the roof side joint 20 and attached. A hole 32 is drilled in one end 30 of the sheet holding member 28. This hole 32 coincides with a hole 34 in the roof side joint 20. A bolt or pin or the like may be passed through these holes 32, 34 to fix the sheet holding member 28 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, 34.

The support-side joint 18 and the roof-side joint 20 are attached by a connecting part 36. For example, the connecting part 36 includes two first plates 38 attached to the support-side joint 18, one second plate 40 attached to the roof-side joint 20 and disposed between the two first plates 38, holes (not shown) provided in the first plate 38 and the second plate 40, and a bolt 42 passing through the holes. A nut 44 may be attached to the shaft of the bolt 42 to fix the first plate 38 and the second plate 40. The shaft of the bolt 42 of the connecting part 36 becomes the rotation shaft, and the roof-side joint 20 rotates. The roof-side joint 20 can rotate with respect to the support-side joint 18. The relative angle between the support-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.

When the bolts 42 and nuts 44 are used as described above, the first plate 38 and the second plate 40 are brought into contact with each other by the bolts 42 and nuts 44, and are fixed to each other. The angle of the roof-side joint 20 relative to the support-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.

The members that make up the roof include a sheet retaining member 28 and a sheet 46. The sheet retaining member 28 is attached to the roof installation tool 10, and then the sheet 46 is attached to obtain the roof structure 14 shown in Figures 4, 5, and 6.

The sheet retaining member 28 is a straight cylinder or rod. The sheet retaining member 28 is made of metal or resin. One end 30 of the sheet retaining member 28 is attached to the roof side joint 20. The other end 48 of the sheet retaining member 28 is not attached anywhere and is placed in space. If at a construction site, the other end 48 of the sheet retaining member 28 may be in contact with the wall of the building 16, etc.

Multiple pillars 12 are arranged at equal intervals. A roof installation device 10 is attached to each pillar 12, and a sheet holding member 28 is further attached to the pillars 12, resulting in a structure in which the sheet holding members 28 are arranged (Figures 5 and 6). Note that adjacent pillars 12 may be fixed to other horizontally oriented pillars, etc.

The sheet retaining member 28 may have a smaller cross section than the support 12. This is to make the sheet retaining member 28 lighter and to make it easier to stabilize the support 12. If the sheet retaining member 28 is tubular, it may be made lighter by reducing its thickness. The sheet retaining member 28 may be made of a material that is lighter than the support 12.

A receiving member 50 may be provided to receive the other end 48 of the sheet holding member 28 or its vicinity from below (Figs. 4 and 7). The receiving member 50 has a recess 52 and a straight portion 54 to receive the sheet holding member 28. The recess 52 has a depression 56 into which the sheet holding member 28 fits. The straight portion 54 is configured as a straight rod or cylinder, with the recess 52 attached to one end and the other end installed on the ground or the eaves. The straight portion 54 may be configured to be extendable and changeable in length. The other end 48 of the sheet holding member 28 or its vicinity can be supported from below, making it easier to stabilize the position of the sheet holding member 28. It is easier to keep the angle of the sheet holding member 28 constant. The structure of the receiving member 50 may be other structures as long as it can receive the sheet holding member 28.

The sheet 46 is placed on the sheet holding members 28 arranged side by side. A string or the like may be attached to the sheet 46, and the string may be tied to the sheet holding members 28, and the sheet 46 may be attached to the sheet holding members 28.

A sheet attachment member 58 may be disposed at or near the other end 48 of the sheet holding member 28. The sheet attachment member 58 is a straight rod or cylinder. A string 60 or the like is attached to the sheet 46, and the string 60 is tied to the sheet attachment member 58. This can prevent the sheet 46 from coming off the sheet holding member 28. A stop member 62 may be provided on the sheet holding member 28 to prevent the sheet attachment member 58 from rolling off the sheet holding member 28. The stop member 62 is a rod or plate, etc., and is disposed on the sheet holding member 28. Even if the sheet attachment member 58 tries to roll on the sheet holding member 28, the stop member 62 catches it, and the sheet attachment member 58 can be prevented from rolling. The stop member 62 may be provided on the sheet attachment portion 58 to prevent the sheet attachment portion 58 from rolling.

The sheet 46 is a flexible sheet-like object, and is preferably made of a material that does not allow rainwater to pass through. By placing the sheet 46 above the scaffolding, work can be carried out even in rainy weather. The sheet 46 may also have light-blocking properties. The sheet 46 blocks direct sunlight on sunny days, making it easier to reduce the physical fatigue of the worker.

As described above, the present invention allows the roof structure 14 to be installed on the scaffolding supports 12, etc., making it possible to carry out work even in rainy weather. Work delays due to weather conditions are less likely to occur. As the roof structure 14 uses a sheet 46, it is easy to attach and detach, and easy to transport.

[Embodiment 2]
The sheet holding member 28 is not limited to being made of a hard material. A part or the whole of the sheet holding member 28 may be made of a flexible resin. For example, as in the sheet holding member 64 of FIG. 8, a portion 66 attached to the roof side joint 20 is made of a hard material, and the other portion 68 is made of a flexible resin. The resin portion is a cylinder with both ends closed. The other portion 68 is made straight by introducing air into it. A check valve may be attached to the portion where air is introduced. Air is introduced through the check valve, and it is possible to prevent air from escaping from the other portion 68. Since a compressor is installed at many construction sites, the compressor may be used to introduce air. The air can be released when the sheet holding member 64 is carried, making it light and easy to carry.

[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. This eliminates the need for an operation for attaching the sheet 46 to the sheet holding member 28.

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

Generally, the width of the building 16 differs from one construction site to another, and the number of scaffolding pillars 12 differs from one construction site to another. The pillars 12 are arranged at regular intervals. Therefore, the length of the sheet 46 in the direction in which the pillars 12 are arranged differs depending on the number of pillars 12 arranged. It is difficult to own all of these sheets 46 of different lengths. As shown in FIG. 11, one sheet 72 and sheet holding members 28 attached to both sides of the sheet 72 are considered as one set. The length of one sheet 72 in the width direction (the direction in which the pillars 12 are arranged) is the same as or slightly longer than the length when the roof side joint 20 is arranged. The number of sets required to construct the roof structure 14 is the number of pillars 12 minus one. There is no need to own sheets 46 of different lengths, which increases versatility.

In order to eliminate gaps between the two sheet holding members 28 attached to one roof installation tool 70, a fixing means for fixing the sheet holding members 28 to each other may be provided. For example, the fixing means may be a string, a belt, a hook-and-loop fastener, etc. By fixing the two sheet holding members 28 to each other, it becomes easier to prevent rain from leaking through the gap.

[Embodiment 5]
The present invention is not limited to a form used beside a building 16. For example, as shown in Figs. 12 and 13, a roof installation tool 10 may be attached to each of the pillars 12 arranged in a first row 74 and the pillars 12 in a second row 76 arranged parallel to the first row 74. Each of the pillars 12 in each row 74 and 76 is arranged to face each other. One end of a sheet holding member 78 is attached to the roof installation tool 10 in the first row 74, and the other end of the sheet holding member 78 is attached to the roof installation tool 10 in the second row 76. The sheet holding member 78 is arranged to bridge between the pillars 12 in the first row 74 and the pillars 12 in the second row 76. A sheet 80 is placed on or attached to the sheet holding member 78 to form a roof structure 82. The center of the sheet holding member 78 may be curved. This makes it easier to place the sheet 80 on the sheet holding member 78, and the sheet 80 is less likely to be damaged.

The roof structure 82 can be installed not only at a construction site, but also anywhere where the support posts 12 can be erected, such as a ground or an open space. If the support posts 12 are provided with a mechanism for adjusting their length, the roof structure 82 can be installed even on a sloped surface. Even in the configurations of Figures 12 and 13, the roof structure may be installed so as to cover the roof of the building 16 as well.

[Embodiment 6]
As shown in Figs. 14 and 15, the present invention may include a rail 84 attached to the upper part of a plurality of columns 12 arranged in a row, and a moving part 86 that moves along the rail 84. The column-side joint 18 of the roof installation device 10 is attached to the moving part 84. The rail 84 may be made of a steel pipe having a circular or rectangular cross section. As long as the rail 84 is attached to the column 12, the mounting method is arbitrary. For example, as shown in Fig. 15, the rail 84 is mounted to the column 12 using a rail mounting tool 88. The rail mounting tool includes a ring part 90 that goes around the rail 84 and a detail part 92. The ring part 90 is attached to the rail 84, and the detail part 92 is attached to the column 12.

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 the shape of a strip that follows the outer shape of the rail 84, with 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 C-shaped. It can pass through the ring part 90 at the support 12 without coming off the rail 84. When passing through the ring part 90, the opening 94 passes through a part with a small part 92.

[Embodiment 7]
The roof side joint 20 is not limited to the above-mentioned form. As shown in FIG. 16, a two-port joint member 96 may be formed by fixing two roof side joints 20 side by side. An insert 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 insert member 98 is inserted into the roof side joint 20 of FIG. 1, etc., and the two-port joint member 96 is attached. The roof installation tool 10 provided with one roof side joint 20 of FIG. 1 becomes the same configuration as the roof installation tool 70 of FIG. 9 provided with two roof side joints 20 by using the two-port joint member 96 of FIG. 16. The insert member 98 may be provided with a hole 32 as in the first embodiment, and may be attached and fixed to the roof side joint 20 by a bolt or the like.

The method of attaching the roof side joint 20 to the connecting part 36 is not limited, and it may be attached directly to the connecting part 36 or via another member. Furthermore, the number of roof side joints 20 attached to the connecting part 36 is not limited to one, and may be two. If there are two, the two-port joint member 96 may be attached directly or indirectly to the connecting part 36.

[Embodiment 8]
The connection between the pole-side joint 18 and the roof-side joint 20 of the roof installation tool 10 is not limited to the above-mentioned method. For example, the connecting part 36 may be a ball joint instead of one having a rotation axis. The angle of the roof-side joint 20 relative to the pole 12 can be changed continuously and freely.

As in the roof installation tool 100 in FIG. 18, the connecting part 102 may not have a rotating mechanism, and the angle of the roof side joint 18 relative to the support 12 may be fixed. This increases the strength of the roof installation tool 100.

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

The pillar-side joint 18 and roof-side joint 20 are not limited to metal products. Reinforced resins and other materials may be used as long as the strength is guaranteed.

In addition, the present invention can be implemented in various forms with improvements, modifications, and changes based on the knowledge of those skilled in the art without departing from the spirit of the invention. The multiple embodiments described are not separate and independent, but can be implemented in appropriate combinations based on the knowledge of those skilled in the art.
