[0010] [First embodiment] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In this specification and drawings, components having substantially the same functional configurations are designated by the same reference numerals, and redundant description will be omitted. As shown in Figure 1, the temporary roof unit system 100 according to the first embodiment comprises a large roof 102, two first temporary roof units 1A and two second temporary roof units 1B that support the large roof 102, and a temporary wall 101. The temporary roof unit system 100 is a facility used to surround a huge structure, such as a transition piece of a jacket structure for offshore wind power generation, to protect the structure from the effects of wind when painting the structure. The first temporary roof unit 1A and the second temporary roof unit 1B have the same configuration, and function as the wall portion of the temporary roof unit system 100 together with the temporary wall 101.

[0011] The large roof 102 is rectangular when viewed vertically, and is formed to a size that corresponds to the size of the object to be enclosed and the other components of the temporary roof unit system 100. The large roof 102 is placed on the roof 4 (see Figure 2) of the temporary roof unit 1 and fixed using predetermined mounting hardware. The large roof 102 comprises a framework made of, for example, steel, and a windshield sheet attached to the framework to block wind. The windshield sheet can be made of canvas or the like.

[0012] The temporary wall 101 is wall-shaped and is configured to be self-supporting with its main surface generally aligned vertically. In the present invention, the main surface having the largest area among the surfaces constituting the temporary wall 101 is referred to as the "main surface." The temporary wall 101 comprises a framework 110 formed, for example, from steel material, and a windshield sheet. The framework 110 comprises a base 111 placed on the ground and a rectangular wall main body 112. The temporary wall 101 is formed to a size corresponding to the size of the object to be enclosed, etc. Additionally, the temporary roof unit system 100 can be supplemented with a predetermined framework scaffolding.

[0013] Next, we will explain the details of the temporary roof units 1 (first temporary roof unit 1A, second temporary roof unit 1B). As shown in Figure 2, the temporary roof unit 1 of this embodiment includes four pillars 2, four first beams 3 connected to the bottom of each pillar 2, a roof 4 connected to the top of the pillars 2, weights 5 attached to the first beams 3, and two suspended members 6. In this embodiment, there are four pillars 2 and first beams 3, but this is not limited to this and the number can be increased or decreased as appropriate depending on the size and strength required for the temporary roof unit 1.

[0014] The pillars 2 are columnar members extending vertically and can be formed, for example, from H-section steel. The length and strength of the pillars 2 can be determined depending on the size of the object to be enclosed, etc. The multiple pillars 2 are arranged parallel to one another.

[0015] The first beam 3 is a member that is placed on the ground or on a raised platform 103 (see FIG. 4) described below so that its longitudinal direction is horizontal. The first beam 3 is connected to the lower part of each pillar 2 by, for example, welding. The first beam 3 can be formed, for example, from an H-shaped steel. The first beam 3 extends in a first direction X1 from the pillar 2. In this specification, the first direction X1 is the direction in which the first beam 3 extends in the temporary roof unit 1. The first direction X1 is a direction that is approximately perpendicular to the extension direction (vertical direction) of the pillar 2, for example, the horizontal direction. Furthermore, in the temporary roof unit 1, the direction that is approximately perpendicular to the first direction X1 and approximately parallel to the horizontal direction is defined as the second direction Y.

[0016] The four columns 2 and four first beams 3 are arranged horizontally so as to be parallel to one another and spaced apart in the second direction Y. The first beams 3 are connected to one another by second beams 7 extending in the second direction Y. One or more second beams 7 can be provided depending on the required strength, and can be connected to the first beams 3 by welding, for example. Like the first beams 3, the second beams 7 can be formed, for example, from H-shaped steel.

[0017] The temporary roof unit 1 of this embodiment is equipped with auxiliary columns 8 to enhance the rigidity of the temporary roof unit 1. The first beam 3 also extends in a direction X2 opposite to the first direction X1, and the auxiliary columns 8 are arranged between the ends of the first beams 3 and the roof 4 so as to be parallel to the columns 2. The pillars 2 and the auxiliary pillars 8 can be connected to each other by a plurality of beam-shaped reinforcing members 9 extending in the second direction Y.

[0018] The roof 4 is connected to the top of the pillars 2 and extends in a direction X2 opposite to the first direction X1. The roof 4 includes roof support beams 41 and a roof body 42 supported by the roof support beams 41. Figure 3 is a schematic diagram illustrating the configuration of the roof 4, viewed along the extension direction of the roof support beam 41. As shown in Figure 3, the roof support beam 41 comprises a beam main body 43 and plate-like members 44 fixed to both sides of the beam main body 43 and extending in the longitudinal direction of the beam main body 43. A roof edge accommodation groove 45 is formed in the roof support beam 41 by the upper surface of the beam main body 43 and the pair of plate-like members 44.

[0019] The roof main body 42 is rectangular, and linear protrusions 46 corresponding to the roof edge accommodating grooves 45 are formed on two parallel sides. The roof 4 is configured so that the linear protrusions 46 of the roof main body 42 are inserted into the roof edge accommodating grooves 45 of the roof support beams 41. With this configuration, the roof main body 42 can be attached and detached to the roof support beams 41. The roof edge accommodating grooves 45 also function as gutters to drain rainwater from the roof 4. A large roof 102 can be placed on the roof 4.

[0020] The suspended member 6 is provided, for example, on the top of one of the four pillars 2, excluding the two at the ends. The suspended member 6 is a portion onto which a crane hook is attached and has a through-hole formed therein. The suspended member 6 is positioned below the roof 4 and protrudes from the pillars 2 in the first direction X1.

[0021] The weight 5 is provided on the first beam 3. The weight 5 has the function of maintaining proper balance of the temporary roof unit 1 when the temporary roof unit 1 is lifted by a crane via the hanged member 6. In other words, the position and weight of the weight 5 are determined so that the temporary roof unit 1 is properly balanced when the temporary roof unit 1 is lifted by a crane via the hanged member 6. Here, proper balance refers to a state in which the pillar 2 does not tilt significantly and the first beam 3 is kept approximately horizontal when the temporary roof unit 1 is lifted by a crane via the hanged member 6. Specifically, the suspended member 6 is positioned approximately at the center of gravity of the temporary roof unit 1 when viewed along the second direction Y by placing a weight 5 of appropriate weight at an appropriate position on the first beam 3. The weight 5 can be formed from a predetermined weight, for example, an H-shaped steel. Note that the position of the suspended member 6 does not need to be exactly at the center of gravity, and may be offset by approximately ±500 mm from the first direction X1.

[0022] In this way, by positioning the suspended member 6 approximately at the center of gravity of the temporary roof unit 1, the temporary roof unit 1 can be transported more easily and stably using a crane. Furthermore, by placing the weight 5 on the first beam 3, the center of gravity of the temporary roof unit 1 can be lowered. Furthermore, since the temporary roof unit 1 can be moved together with the weight 5, the temporary roof unit 1 can be moved more easily.

[0023] In this embodiment, the two weights 5 are arranged spaced apart in the second direction Y, and a space S into which the forks of a lift are inserted is provided between the two weights 5. In this way, by providing the space S between the two weights 5, it becomes easier to move the temporary roof unit 1 using a lift.

[0024] Scaffolding 10 for workers can be provided on the temporary roof unit 1. The scaffolding 10 can be placed on the opposite side of the column 2 from the suspended member 6. In this embodiment, the scaffolding 10 is fixed to the column 2 and the auxiliary column 8. Furthermore, in addition to the scaffolding 10, stairs and handrails can also be provided on the column 2.

[0025] Returning to FIG. 1 , in the temporary roof unit system 100, the first direction X1 (extension direction of the first beam 3) of the first temporary roof unit 1A and the first direction X1 of the second temporary roof unit 1B are approximately parallel, and the two first temporary roof units 1A are arranged side by side to support one end of the main roof 102, and the two second temporary roof units 1B are arranged side by side to support the other end of the main roof 102. Furthermore, the temporary wall 101 is arranged so that its main surface is approximately aligned with the first direction X1 of the first temporary roof unit 1A and approximately aligned with the first direction X1 of the second temporary roof unit 1B. Furthermore, the weight 5 is connected to the end of the main roof 102 via a rope-like body 114. Note that the main surface of the temporary wall 101 and the first direction X1 of the temporary roof unit 1 do not need to be strictly aligned, and may be tilted by approximately ±20°.

[0026] The large roof 102 is formed so as to overlap the hanged member 6 of the first temporary roof unit 1A when viewed in the vertical direction. In other words, the large roof 102 protrudes in the first direction X1 beyond the hanged member 6. This makes it easy to connect the weight 5 and the end of the large roof 102 via the rope-like body 114. Furthermore, as described above, the suspended member 6 is positioned below the roof 4, and the end of the large roof 102 is positioned above the suspended member 6. This prevents interference between the large roof 102 placed on the roof 4 and the suspended member 6, making it easier to place the large roof 102 on the roof 4.

[0027] According to the above embodiment, a weight 5 is attached to the first beam 3 extending in the first direction X1, and is balanced with the roof 4 extending in the direction X2 opposite to the first direction X1, thereby providing a temporary roof unit 1 that can be installed stably and transported by a hoist.

[0028] In addition, when the temporary roof units 1 are arranged adjacent to each other in the second direction Y, it is possible to prevent the suspended member 6 from interfering with the adjacent temporary roof units 1, making it easier to move the temporary roof units 1 with a hoist. Also, by providing the scaffolding, stairs, handrails, etc. on the pillars 2 on the opposite side of the pillars 2 from the suspended member 6, it is possible to prevent the scaffolding, etc. from getting in the way when lifting the temporary roof unit 1 with a hoist.

[0029] Furthermore, by providing the suspended member 6 on the pillar 2, it is possible to lift the temporary roof unit with a hoist without interfering with the roof 4. Furthermore, by providing the suspended member 6 so that it protrudes in the first direction X1, even when the temporary roof units are arranged adjacent to each other along the second direction Y, as in this embodiment, it is possible to prevent the suspended member 6 from interfering with the adjacent temporary roof unit 1, making it easier to move the temporary roof unit with a hoist.

[0030] Furthermore, since the suspended member 6 is provided on the top of all four pillars 2 except for the pillars 2 at both ends, it becomes easier to ensure the elevation angle of the sling wire when transporting the temporary roof unit 1 using a crane, even when a short sling wire is used.

[0031] Furthermore, since the roof 4 is detachable, it can be removed and transported when moving the temporary roof unit 1 with a crane. Furthermore, when enclosing a huge structure, removing the roof 4 can reduce interference with the structure.

[0032] In this embodiment, the suspended member 6 is attached to the pillar 2, but this is not limited to this and the suspended member 6 can also be attached to the roof 4 as long as it can be stably suspended by a crane. Furthermore, in this embodiment, the end of the main roof 102 is supported by two temporary roof units 1, but the number of temporary roof units 1 can be changed as appropriate.

[0033] [How to remove a temporary roof unit system] Next, a method for removing the temporary roof unit system of this embodiment will be described. The method for removing a temporary roof unit system is a method for removing a temporary roof unit system comprising the above-described temporary roof unit 1 and the main roof 102. The method for removing the temporary roof unit system includes a large roof removal step for removing the large roof 102 from the roof 4 of the temporary roof unit 1, and a temporary roof unit moving step for moving the temporary roof unit 1 by a crane after the large roof removal step.

[0034] According to this method for removing a temporary roof unit system, the temporary roof unit 1 is moved after the main roof 102 is removed, so that the temporary roof unit 1 can be easily moved by a crane.

[0035] Second Embodiment Next, a temporary roof unit system according to a second embodiment of the present invention will be described. Fig. 4 is a front view of a temporary roof unit system 100A according to this embodiment. As shown in Fig. 4, the temporary roof unit system 100A of this embodiment comprises a first temporary roof unit 1A and a temporary wall 101. The temporary wall 101 is arranged so that its main surface is substantially aligned with the first direction X1 of the first temporary roof unit 1A. One end of the large roof 102 of the temporary roof unit system 100A is supported by the temporary roof unit 1 raised by the raised platform 103, and the other end of the large roof 102 is supported only by the raised platform 103. The raised platform 103 is fixed to the bottom of the temporary roof unit 1 with predetermined mounting brackets. The raised platforms 103 can also be fixed to each other with predetermined mounting brackets. In this way, the temporary roof unit system using the temporary roof unit 1 is not limited to the temporary roof unit system 100 of the first embodiment, but can be applied to various types of temporary roof unit systems.

[0036] [Storage method for temporary roof unit system] Next, a method for storing the temporary roof unit system 100 having a plurality of temporary roof units 1 in a predetermined location when the temporary roof unit system 100 is not in use will be described. 5 is a diagram illustrating a method for storing a temporary roof unit system according to this embodiment. The method for storing a temporary roof unit system is a method for storing a temporary roof unit system comprising a first temporary roof unit 1A and a second temporary roof unit 1B, and includes an arrangement step of arranging the second temporary roof unit 1B on the first direction X1 side of the first temporary roof unit 1A when viewed horizontally so that the first beam 3 of the first temporary roof unit 1A and the roof 4 of the second temporary roof unit 1B overlap when viewed vertically.

[0037] That is, in the storage method of the temporary roof unit system of this embodiment, the two temporary roof units 1 are arranged so that the first direction X1 of the first temporary roof unit 1A and the first direction X1 of the second temporary roof unit 1B face in approximately the same direction, and so that the second temporary roof unit 1B is on the side of the first direction X1 of the first temporary roof unit 1A. Furthermore, the first beam 3 of the first temporary roof unit 1A and the roof 4 of the second temporary roof unit 1B are arranged so as to overlap when viewed in the vertical direction. In other words, the first beam 3 of the first temporary roof unit 1A is arranged so as to be inserted under the roof 4 of the second temporary roof unit 1B.

[0038] According to the above embodiment, the first beam 3 of the first temporary roof unit 1A is inserted under the roof 4 of the second temporary roof unit 1B, thereby reducing the space required to store the first temporary roof unit 1A and the second temporary roof unit 1B. Although the above describes a method for storing a temporary roof unit system using an example of a method for storing a temporary roof unit system having two temporary roof units 1, the number of temporary roof units is not limited to this. For example, three or more temporary roof units can also be stored in the same way. [Explanation of symbols]
