[0003] [Patent Document 1] Japanese Patent Publication No. 2022-36725 Summary of the Invention [Problem to be solved by the invention]

[0004] The temporary rainproof device disclosed in Patent Document 1 has a roof connection section that is detachable from the roof of an outdoor structure. This allows the temporary rainproof device to be attached to a package house during maintenance and inspection work on a distribution board, and then removed from the package house and stored in a designated location when work is not being performed. Therefore, the temporary rainproof device can be removed from its storage location when work is scheduled and used only when protection for the distribution board is necessary, taking into account the weather at the site, allowing maintenance and inspection work to be performed regardless of the weather. However, it is not possible to move an outdoor structure from a designated location to a facility location while preventing it from getting wet in rain, and it is not possible to install an outdoor structure at a facility location while preventing it from getting wet after being moved to the facility location.

[0005] An object of the present invention is to provide a rainproof structure that can protect an assembly from rain in rainy weather, prevent the assembly from getting wet, and enable the assembly to be moved from a predetermined location to a facility location while being protected from rain.

[0017] According to the rainproof structure of the present invention, when the horizontal lifting member connected to the first and second vertical rods is lifted into the air by the lifting rope of the lifting mechanism, the rainproof sheet is positioned above the assembly, and the rainproof sheet slopes downward from the first side edge of the frame to the second side edge, so that rainwater falling on the rainproof sheet flows over the rainproof sheet from the first side edge of the frame to the second side edge.This means that the rainproof sheet can protect the assembly from rain in rainy weather, and installation work can be carried out to install the assembly at the facility location while preventing it from getting wet.

Rainwater flowing on the rainproof sheet 12 from the third frame rod 27c (first side edge) toward the fourth frame rod 27d (second side edge) flows along the sixth water guide plate 25f, and therefore the rainwater does not flow into the sixth opening 22f.

[0069] A bolt is inserted or screwed into the bolt hole 18 at the upper end of the first vertical rod 16 located on the side of the first frame rod 27a (first edge), and a bolt is inserted or screwed into the bolt hole of the first detachable portion 24a formed in the lower web at one end of the first horizontal rod 41a, and the upper end of the first vertical rod 16 located on the side of the first frame rod 27a and the first detachable portion 24a of the first horizontal rod 41a are firmly connected by the bolt and nut. A bolt is inserted or screwed into the bolt hole 19 at the upper end of the second vertical rod 17 located on the side of the first frame rod 27a (first edge), and a bolt is inserted or screwed into the bolt hole of the second detachable portion 24b formed in the lower web at the other end of the first horizontal rod 41a, and the upper end of the second vertical rod 17 located on the side of the first frame rod 27a (first edge) and the second detachable portion 24b of the first horizontal rod 41a are firmly connected by the bolt and nut.

[0070] A bolt is inserted or screwed into the bolt hole 18 at the upper end of the first vertical rod 16 located toward the center of the front-to-rear direction of the third frame rod 27c (first side edge), and a bolt is inserted or screwed into the bolt hole of the third detachable portion 24c formed in the lower web at one end of the second horizontal rod 41b, and the bolt and nut firmly connect the upper end of the first vertical rod 16 located toward the center of the front-to-rear direction of the third frame rod 27c to the third detachable portion 24c of the second horizontal rod 41b. A bolt is inserted or screwed into the bolt hole 19 at the upper end of the second vertical rod 17 located toward the center of the fore-and-aft direction of the fourth frame rod 27d (second side edge), and a bolt is inserted or screwed into the bolt hole of the fourth detachable portion 24d formed in the lower web at the other end of the second horizontal rod 41b, and the bolt and nut firmly connect the upper end of the second vertical rod 17 located toward the center of the fore-and-aft direction of the fourth frame rod 27d to the fourth detachable portion 24d of the second horizontal rod 41b.

[0071] A bolt is inserted or screwed into the bolt hole 18 at the upper end of the first vertical rod 16 located on the side of the second frame rod 27b (second edge), and a bolt is inserted or screwed into the bolt hole of the fifth detachable portion 24e formed (drilled) in the lower web at one end of the third horizontal rod 41c, and the upper end of the first vertical rod 16 located on the side of the second frame rod 27b and the fifth detachable portion 24e of the third horizontal rod 41c are firmly connected by the bolt and nut. A bolt is inserted or screwed into bolt hole 19 in the upper end of second vertical rod 17 located on the second frame rod 27b (second edge) side, and a bolt is inserted or screwed into bolt hole 24f in the sixth detachable portion 24f formed in the lower web at the other end of third horizontal rod 41c, and the upper end of second vertical rod 17 located on the second frame rod 27b side and sixth detachable portion 24f of third horizontal rod 41c are firmly connected by the bolt and nut. Connecting the upper ends of first vertical rod 16 and second vertical rod 17 to first to sixth detachable portions 24a to 24f connects frame 11, rainproof sheet 12 (waterproof sheet) and horizontal lifting member 20.

[0072] As shown in Fig. 6, the first to sixth auxiliary rainproof sheets 26a to 26f have a rectangular planar shape and an area larger than that of the first to sixth openings 22a to 22f. They block the first to sixth openings 22a to 22f when the wooden prefabricated house 44 is installed or when the rainproof structure 10 is not in use, preventing rainwater from entering the first to sixth openings 22a to 22f. The first to sixth auxiliary rainproof sheets 26a to 26f have opposite ends extending laterally and opposite side ends extending in the front-to-rear direction. The first to sixth auxiliary rainproof sheets 26a to 26f are made from the same materials as the rainproof sheet 12, such as PVC sheets, polyethylene sheets, polyester sheets, waterproof hoods, or tarpaulin sheets made of polyester fiber fabric sandwiched between synthetic resin films.

[0073] Mechanical fasteners 45 (male hook-and-loop fasteners) are attached to the inner surfaces of both ends of the first to sixth auxiliary rainproof sheets 26a to 26f. For example, as shown in Fig. 7, when the first auxiliary rainproof sheet 26a is placed on the first opening 22a (rainproof sheet 12) so as to close the first opening 22a, the mechanical fasteners 45 of the first auxiliary rainproof sheet 26a engage with the rainproof sheet 12 surrounding the first opening 22a, and the first auxiliary rainproof sheet 26a is connected to the rainproof sheet 12, maintaining the state in which the first opening 22a is closed by the first auxiliary rainproof sheet 26a. Conversely, when the engagement between the mechanical fasteners 45 and the rainproof sheet 12 is released and the first auxiliary rainproof sheet 26a is removed from the first opening 22a, the first opening 22a is opened.

[0074] The rainproof structure 10 has a lateral length dimension greater than the lateral length dimension of the wooden prefabricated house 44, a front-to-back length dimension greater than the front-to-back length dimension of the wooden prefabricated house 44, and an area (including the frame and rainproof sheet) greater than the area of ​​the orthogonal laminated ceiling boards 46 (orthogonal laminated floor boards 47) of the wooden prefabricated house 44 described below.

[0075] Fig. 8 is a perspective view showing an example of a wooden prefabricated house 44 that uses the rainproof structure 10, and Fig. 9 is a perspective view of the wooden prefabricated house 44 of Fig. 6 as seen from the rear side. Fig. 10 is a front view of the wooden prefabricated house 44 of Fig. 8. In Fig. 7, the front-to-rear direction is indicated by arrow X, the lateral direction is indicated by arrow Y, and the up-down direction is indicated by arrow Z.

[0076] The wooden modular houses 44 (assemblies) using the rainproof structures 10 are assembled in an assembly factory, then transported to the facility site by a predetermined means of transportation and erected in a predetermined installation position at the facility site. By assembling a plurality of different types of wooden modular houses 44 and erecting them in the installation position, wooden modular houses with various floor plans can be created. Transportation means include transport vehicles, railways, and ships.

[0077] The wooden prefabricated house 44 is made up of horizontally extending cross-laminated ceiling panels 46 (wood ceiling plates) of a specified area, horizontally extending cross-laminated floor panels 47 (wood floor plates) of a specified area, and vertically extending wood wall panels 48 of a specified area. The cross-laminated ceiling panels 46 and the cross-laminated floor panels 47 are approximately the same shape and size. The cross-laminated ceiling panels 46 and the cross-laminated floor panels 47 are made of CLT (Cross Laminated Timber), which is made by arranging planks (lamina) and then laminating and bonding them with an adhesive (aqueous polymer isocineate resin adhesive (non-formaldehyde adhesive)) so that the fiber directions are perpendicular to each other.

[0078] CLT can be made up of three layers (3 ply), three layers (4 ply), five layers (5 ply), five layers (7 ply), seven layers (7 ply), or nine layers (9 ply). CLT can be made up of cedar CLT panels, cypress CLT panels, larch CLT panels, and todomatsu CLT panels. CLT has excellent thermal insulation and energy-saving properties, and is earthquake-resistant, while being lighter than reinforced concrete. Any type of CLT that will be developed in the future can be used.

[0079] The cross-laminated ceiling boards 46 of the wooden prefabricated house 44 are formed into a generally rectangular shape that is long in the front-to-rear direction, and have first and second end edges that extend laterally, and first and second side edges that extend in the front-to-rear direction. The cross-laminated ceiling boards may also be formed into a generally rectangular shape that is long in the width direction. A plurality of rafters extending in the width direction are arranged on the upper surface of the cross-laminated ceiling boards 46 at equal intervals in the front-to-rear direction. Sheathing plywood is attached to the rafters. The rafters and sheathing plywood are fixed to the cross-laminated ceiling boards 46 (CLT) with long screws (not shown).

[0080] The orthogonal laminated floorboards 47 of the wooden prefabricated house 44 are formed in a generally rectangular shape that is long in the front-to-rear direction, and have first and second end edges that extend laterally, and first and second side edges that extend in the front-to-rear direction. Flooring is applied to the upper surfaces of the orthogonal laminated floorboards 47. The flooring (soundproof wooden flooring with special cushioning material that improves sound insulation performance) is bonded to the upper surfaces of the orthogonal laminated floorboards 47 with adhesive. It is also possible to use a joist construction method in which multiple joists are placed on the upper surface of the orthogonal laminated floorboards 47, flooring is placed so that it is perpendicular to the joists, and the flooring is fixed to the joists with adhesive and nails.

[0081] The wooden wall panels 48 of the wooden prefabricated house 44 are formed from a first wooden wall panel 48a of a predetermined area extending laterally, a second wooden wall panel 48b of a predetermined area extending laterally, and a third wooden wall panel 48c of a predetermined area extending in the front-to-rear direction. The first to third wooden wall panels 48a to 48c are made by the two-by-four construction method using two-by-four lumber (2x4 lumber) and are formed into a substantially rectangular shape.

[0082] Although not shown, the first to third wood-based wall panels 48a to 48c are formed from a top joint (square timber) and an upper frame (square timber) extending in the front-to-back or width direction, a lower frame (square timber) located vertically below the upper frame and extending in the front-to-back or width direction, a first vertical frame (square timber) located between the upper and lower frames and extending in the vertical direction, a second vertical frame (square timber) extending vertically opposite the first vertical frame and spaced apart in the front-to-back or width direction, and a plurality of studs (square timbers) located between the first and second vertical frames, extending in the vertical direction, and spaced apart in the front-to-back or width direction.

[0083] The head joint, upper frame, lower frame, first vertical frame, second vertical frame, and studs are connected with standardized nails. The first to third wooden wall panels 48a to 48c are made by assembling each piece of 2x4 lumber (head joint, upper frame, lower frame, first vertical frame, second vertical frame, and studs) to form a "framework" that forms a highly rigid diaphragm.

[0084] The first wood-based wall panel 48a has an upper end (head joint and upper frame) extending in the width direction, a lower end (lower frame) located vertically below the upper end and extending in the width direction, and both side edges (first vertical frame, second vertical frame) extending vertically from the upper end to the lower end. Window frames (sashes) and door frames of various shapes are made from the first wood-based wall panel 48a.

[0085] The second wood wall panel 48b faces the first wood wall panel 48a at a distance in the front-to-rear direction. The second wood wall panel 48b has an upper end (head joint and upper frame) extending in the width direction, a lower end (lower frame) located vertically below the upper end and extending in the width direction, and both side edges (first vertical frame, second vertical frame) extending in the vertical direction from the upper end to the lower end. Window frames (sashes) and door frames of various shapes are made from the second wood panel 48b.

[0086] The third wood-based wall panel 48c is located between the side edges of the first wood-based wall panel 48a and the second wood-based wall panel 48b. The third wood-based wall panel 48c has an upper end (head joint and upper frame) extending in the front-to-rear direction, a lower end (lower frame) located vertically below the upper end and extending in the front-to-rear direction, and side edges (first vertical frame and second vertical frame) extending vertically from the upper end to the lower end. Window frames (sashes) of various shapes are made in the third wood-based panel 48c. Although not shown, electrical appliances such as wiring cables, outlet boxes, and outlet plates, plumbing equipment such as water supply and drainage pipes, and air conditioning equipment such as piping and ducts are installed in the first to third wood-based wall panels 48a to 48c, and holes for ventilation openings and air conditioner refrigerant pipes and drain hoses are drilled.

[0087] In a wooden prefabricated house 44, first to third wood wall panels 48a to 48c are connected to an orthogonally laminated ceiling board 46 and an orthogonally laminated floor board 47, the first wood wall panel 48a is connected to the third wood wall panel 48c, and the second wood wall panel 48b is connected to the third wood wall panel 48c. By connecting the first to third wood wall panels to the orthogonally laminated ceiling board 46 and the orthogonally laminated floor board 47 and by connecting the first to third wood wall panels to each other, an interior living space 49 of a predetermined volume that is long in the front-to-back direction (or width direction) is defined, surrounded by the orthogonally laminated ceiling board 46, the orthogonal laminated floor board 47, and the first to third wood wall panels 48a to 48c.

[0088] The orthogonally laminated ceiling board 46 and the first to third wooden wall panels 48a to 48c are connected with hold-down hardware (pulling hardware) and at least diagonal long screws out of vertical long screws (vertical screws) and diagonal long screws (diagonal screws). The orthogonally laminated floor board 47 and the first to third wooden wall panels 48a to 48c are connected with hold-down hardware (pulling hardware) and at least diagonal long screws out of vertical long screws (vertical screws) and diagonal long screws (diagonal screws). The first to third wooden wall panels 48a to 48c are connected to each other with long screws.

[0089] Fig. 11 is a diagram illustrating the moving work of a wooden prefabricated house 44 that uses the rainproof structure 10 in rainy weather, and Fig. 12 is a diagram illustrating the construction (installation) work of a wooden prefabricated house 44 that uses the rainproof structure 10 in rainy weather. As shown in Fig. 11, the wooden prefabricated house 44 is entirely covered with a waterproof sheet 50 during the moving work.

[0090] An example of the procedure for using the rainproof structure 10 is as follows: The tip of a lifting rope 43 attached to the hook of a crane (lifting mechanism) (not shown) is connected to the first to fourth connecting portions 21a to 21d (first to fourth connecting hooks) of the horizontal lifting member 20, and the crane is used to lift the rainproof structure 10 to a first height (about chest height of a worker). When the rainproof structure 10 is lifted to the first height and the horizontal lifting member 20 is lifted into the air, the horizontal lifting member 20 is held horizontal to the ground, and because the vertical dimension of the second vertical rods 17 is longer than the vertical dimension of the first vertical rods 16, the frame 11 and the rainproof sheet 12 are inclined downward at a predetermined angle from the third frame rod 27c (first side edge) toward the fourth frame rod 27d (second side edge).

[0091] Next, one end (tying string) of the hanging rope 51 is fastened (fastened) to the first fastening portion 23a (first fastening hook), the first auxiliary rainproof sheet 26a is removed from the first opening 22a to open the first opening 22a, and then the hanging rope 51 is inserted through the first opening 22a and allowed to hang down (hang down) from the first opening 22a. The belt-shaped hanging rope 51 passes from the first fastening portion 23a through the first opening 22a and hangs down below the rainproof structure 10. Although not shown, a mechanical fastener (male hook-and-loop fastener) of a predetermined area extending in the length direction is attached to the inner surface of the belt-shaped hanging rope 51 hanging down from the first opening 22a.

[0092] One end (tying string) of the hanging rope 51 is fastened (fastened) to the second locking portion 23b (second locking hook), and after the second auxiliary rainproof sheet 26b is removed from the second opening 22b to open the second opening 22b, the hanging rope 51 is inserted through the second opening 22b and allowed to hang down (hang down) from the second opening 22b. The belt-shaped hanging rope 51 passes from the second locking portion 23b through the second opening 22b and hangs down below the rainproof structure 10. Although not shown, a mechanical fastener (male hook-and-loop fastener) of a predetermined area extending in the length direction is attached to the inner surface of the belt-shaped hanging rope 51 hanging down from the second opening 22b.

[0093] One end (tying string) of the hanging rope 51 is fastened (fastened) to the third fastening portion 23c (third fastening hook), and after the third auxiliary rainproof sheet 26c is removed from the third opening 22c to open the third opening 22c, the hanging rope 51 is inserted through the third opening 22c and allowed to hang down (hang down) from the third opening 22c. The belt-shaped hanging rope 51 passes from the third fastening portion 23c through the third opening 22c and hangs down below the rainproof structure 10. Although not shown, a mechanical fastener (male hook-and-loop fastener) of a predetermined area extending in the length direction is attached to the inner surface of the belt-shaped hanging rope 51 hanging down from the third opening 22c.

[0094] One end (tying string) of the hanging rope 51 is fastened (fastened) to the fourth locking portion 23d (fourth locking hook), and after the fourth auxiliary rainproof sheet 26d is removed from the fourth opening 22d to open the fourth opening 22d, the hanging rope 51 is inserted through the fourth opening 22d and allowed to hang down (hang down) from the fourth opening 22d. The belt-shaped hanging rope 51 passes from the fourth locking portion 23d through the fourth opening 22d and hangs down below the rainproof structure 10. Although not shown, a mechanical fastener (male hook-and-loop fastener) of a predetermined area extending in the length direction is attached to the inner surface of the belt-shaped hanging rope 51 hanging down from the fourth opening 22d.

[0095] Furthermore, one end (tying string) of the hanging rope 51 is fastened (fastened) to the fifth locking portion 23e (fifth locking hook), the fifth auxiliary rainproof sheet 26e is removed from the fifth opening 22e to open the fifth opening 22e, and then the hanging rope 51 is inserted through the fifth opening 22e and allowed to hang down (hang down) from the fifth opening 22e. The belt-shaped hanging rope 51 passes from the fifth locking portion 23e through the fifth opening 22e and hangs down below the rainproof structure 10. Although not shown, a mechanical fastener (male hook-and-loop fastener) of a predetermined area extending in the length direction is attached to the inner surface of the belt-shaped hanging rope 51 hanging down from the fifth opening 22e.

[0096] One end (tying string) of the hanging rope 51 is fastened (fastened) to the sixth locking portion 23f (sixth locking hook), and after the sixth auxiliary rainproof sheet 26f is removed from the sixth opening 22f to open the sixth opening 22f, the hanging rope 51 is inserted through the sixth opening 22f and allowed to hang down (hang down) from the sixth opening 22f. The belt-shaped hanging rope 51 passes from the sixth locking portion 23f through the sixth opening 22f and hangs down below the rainproof structure 10. Although not shown, a mechanical fastener (male hook-and-loop fastener) of a predetermined area extending in the length direction is attached to the inner surface of the belt-shaped hanging rope 51 hanging down from the sixth opening 22f.

[0097] After the hanging ropes 51 are attached to the first to sixth fastening portions 23a to 23f of the rainproof structure 10, the rainproof structure 10 is raised to the second height (a position slightly higher than the height of the prefabricated wooden house 44) by a crane, and the rainproof structure 10 is moved to directly above the prefabricated wooden house 44 (orthogonally laminated ceiling panels 46) by the crane. When the rainproof structure 10 is moved to directly above the prefabricated wooden house 44, the belt-shaped hanging ropes 51 hanging down from the first to third openings 23a to 23c hang down just outside one side of the prefabricated wooden house 44, and the belt-shaped hanging ropes 51 hanging down from the fourth to sixth openings 23d to 23f hang down just outside the other side of the prefabricated wooden house 44.

[0098] Next, the inner surfaces of the hanging ropes 51 hanging down from the first to third openings 23a to 23c are pressed against the waterproof sheet 50 covering the wooden prefabricated house 44, so that the mechanical fasteners attached to the inner surfaces of the hanging ropes 51 engage with the waterproof sheet 50, and the hanging ropes 51 are connected to the waterproof sheet 50 (one side of the wooden prefabricated house 44), and the inner surfaces of the hanging ropes 51 hanging down from the fourth to sixth openings 23d to 23f are pressed against the waterproof sheet 50 covering the wooden prefabricated house 44, so that the mechanical fasteners attached to the inner surfaces of the hanging ropes 51 engage with the waterproof sheet 50, and the hanging ropes 51 are connected to the waterproof sheet 50 (the other side of the wooden prefabricated house 44).

[0099] After connecting the suspending ropes 51 to the waterproof sheet 50 (the side of the prefabricated wooden house 44), the rainproof structure 10 is raised by a crane to a third height (the height at which the prefabricated wooden house 44 is lifted into the air). When the rainproof structure 10 is raised to the third height, the prefabricated wooden house 44 is suspended from the suspending ropes 51 and is lifted into the air. After the rainproof structure 10 is raised to the third height by the crane, the crane is moved to move the rainproof structure 10, and as shown in Figure 11, the wooden prefabricated house 44 suspended below the rainproof structure 10 during rainy weather is moved together with the rainproof structure 10 to its facility (installation) location.

[0100] Because the frame 11 and the rainproof sheet 12 are inclined downward at a predetermined angle from the third frame rod 27c (first side edge) to the fourth frame rod 27d (second side edge), rainwater that falls on the rainproof sheet 12 flows from the third frame rod 27c to the fourth frame rod 27d and then flows down from the fourth frame rod 27d to the ground. When rainwater flows from the third frame rod 27c to the fourth frame rod 27d, the rainwater flowing on the rainproof sheet 12 flows along the first water guide plate 25a, so the rainwater does not flow into the first opening 22a, and because the rainwater flowing on the rainproof sheet 12 flows along the second water guide plate 25b, the rainwater does not flow into the second opening 22b.

[0101] Furthermore, rainwater flowing on the rainproof sheet 12 flows along the third water guide plate 25c, so the rainwater does not flow into the third opening 22c, and rainwater flowing on the rainproof sheet 12 flows along the fourth water guide plate 25d, so the rainwater does not flow into the fourth opening 22d. Furthermore, rainwater flowing on the rainproof sheet 12 flows along the fifth water guide plate 25e, so the rainwater does not flow into the fifth opening 22e, and rainwater flowing on the rainproof sheet 12 flows along the sixth water guide plate 25f, so the rainwater does not flow into the sixth opening 22f.

[0102] The rainproof structure 10 uses hanging ropes 51 that hang (extend) downward from the first to sixth openings 22a to 22f of the rainproof sheet 12 to hang the wooden prefabricated house 44 (assembly) below the rainproof structure 10, so that the wooden prefabricated house 44 located below the rainproof structure 10 can be moved together with the rainproof structure 10 from a predetermined location to a facility (installation) location while being protected from rain, and the wooden unit house 45 consisting of orthogonal laminated ceiling panels 46 and orthogonal laminated floor panels 47 made from CLT and wooden wall panels 48a to 48c made from two-by-four lumber can be moved to the facility location while preventing the wooden prefabricated house 44 from getting wet in the rain.

[0103] In the rainproof structure 10, rainwater flowing on the rainproof sheet 12 from the third frame rod 27c (first side edge) of the frame 11 toward the fourth frame rod 27d (second side edge) is directed away from the first to sixth openings 22a to 22f by the mountain-shaped first to sixth water guide plates 25a to 25f, so that the rainwater does not flow downward from the first to sixth openings 22a to 22f. As a result, the wooden prefabricated house 44 (assembly) located directly below (below) the rainproof structure 10 can be moved from a predetermined location to a facility location while being protected from the rain, and a wooden unit house 45 consisting of cross-laminated ceiling boards 46 and cross-laminated floor boards 47 made from CLT and wooden wall panels 48a to 48c made from two-by-four lumber can be moved to the facility location while preventing the wooden prefabricated house 44 from getting wet in the rain.

[0104] The wooden prefabricated house 44 (assembly) is moved to the installation (installation) location together with the rainproof structure 10 by a crane, and then the wooden prefabricated house 44 is lowered to the installation location together with the rainproof structure 10 by a crane, and the wooden prefabricated house 44 is lowered onto a foundation (not shown). When the wooden prefabricated house 44 is lowered onto the foundation, the cross-laminated floor panels 47 of the wooden prefabricated house 44 abut against the foundation. After the wooden prefabricated house 44 is lowered onto the foundation at the installation location, the connection between the hanging ropes 51 and the waterproof sheet 50 covering the wooden prefabricated house 44 by the mechanical fasteners is released.

[0105] Next, one end (tying cord) of the hanging rope 51 is untie|released from the first locking part 23a (first locking hook), and the hanging rope 51 attached to the first locking part 23a is removed, one end (tying cord) of the hanging rope 51 is untie|released from the second locking part 23b (second locking hook), and the hanging rope 51 attached to the second locking part 23b is removed, one end (tying cord) of the hanging rope 51 is untie|released from the third locking part 23c (third locking hook), and the hanging rope 51 attached to the third locking part 23c is removed, one end (tying cord) of the hanging rope 51 is untie|released from the fourth locking part 23d (fourth locking hook), and the hanging rope 51 attached to the fourth locking part 23d is removed. Furthermore, one end (tying string) of the hanging rope 51 is untied from the fifth locking portion 23e (fifth locking hook), the hanging rope 51 attached to the fifth locking portion 23e is removed, one end (tying string) of the hanging rope 51 is untied from the sixth locking portion 23f (sixth locking hook), and the hanging rope 51 attached to the sixth locking portion 23f is removed. The state in which the rainproof structure 10 is suspended in the air by the crane (the state in which the rainproof structure 10 is positioned directly above the wooden prefabricated house 44 (orthogonal laminated ceiling boards 46)) is maintained.

[0106] After removing the hanging ropes 51 from the rainproof structure 10, the first auxiliary rainproof sheet 26a is placed on the first opening 22a (rainproof sheet 12) to close the first opening 22a, and the mechanical fasteners of the first auxiliary rainproof sheet 26a are engaged with the rainproof sheet 12 to close the first opening 22a with the first auxiliary rainproof sheet 26a. The second auxiliary rainproof sheet 26b is placed on the second opening 22b (rainproof sheet 12) to close the second opening 22b, and the mechanical fasteners of the second auxiliary rainproof sheet 26b are engaged with the rainproof sheet 12 to close the second opening 22b with the second auxiliary rainproof sheet 26b. A third auxiliary rainproof sheet 26c is placed on top of the third opening 22c (rainproof sheet 12) so as to block the third opening 22c, and the mechanical fasteners of the third auxiliary rainproof sheet 26c are engaged with the rainproof sheet 12 to block the third opening 22c with the third auxiliary rainproof sheet 26c.

[0107] The fourth auxiliary rainproof sheet 26d is placed on the fourth opening 22d (rainproof sheet 12) to close the fourth opening 22d, and the mechanical fasteners of the fourth auxiliary rainproof sheet 26d are engaged with the rainproof sheet 12 to close the fourth opening 22d by the fourth auxiliary rainproof sheet 26d. The fifth auxiliary rainproof sheet 26e is placed on the fifth opening 22e (rainproof sheet 12) to close the fifth opening 22e, and the mechanical fasteners of the fifth auxiliary rainproof sheet 26e are engaged with the rainproof sheet 12 to close the fifth opening 22e by the fifth auxiliary rainproof sheet 26e. A sixth auxiliary rainproof sheet 26f is placed on top of the sixth opening 22f (rainproof sheet 12) so as to close the sixth opening 22f, and the mechanical fasteners of the sixth auxiliary rainproof sheet 26f are engaged with the rainproof sheet 12 to close the sixth opening 22f with the sixth auxiliary rainproof sheet 26f.

[0108] After the first to sixth openings 22a to 22f have been blocked with the first to sixth auxiliary rainproof sheets 26a to 26f, the rainproof structure 10 is suspended in the air by a crane (the rainproof structure 10 is positioned directly above the wooden prefabricated house 44 (orthogonally laminated ceiling boards 46)), and the waterproof sheet 50 covering the entire wooden prefabricated house 44 is removed from the wooden prefabricated house 44, and various installation (construction) work is carried out on the wooden prefabricated house 44 placed on the foundation.

[0109] The crane maintains the suspended state of the rainproof structure 10, and the rainproof structure 10 is positioned directly above the wooden prefabricated house 44 placed on the foundation. Because the rainproof sheet 12 slopes downward from the third frame rod 27c (first side edge) of the frame 11 to the fourth frame rod 27d (second side edge), rainwater that falls on the rainproof sheet 12 (rainproof structure 10) flows over the rainproof sheet 12 from the third frame rod 27c (first side edge) to the fourth frame rod 27d (second side edge) of the frame 11, and then falls from the fourth frame rod 27d below the rainproof structure 10. Because the wooden prefabricated house 44 is positioned directly below the rainproof sheet 12 (rainproof structure 10) and is entirely covered by the rainproof sheet 12 (rainproof structure 10), the wooden prefabricated house 44 will not get wet in rainy weather. During the installation of the wooden prefabricated house 44, after the waterproofing work (sheet waterproofing, coating waterproofing, asphalt waterproofing) of the orthogonally laminated ceiling boards 46 (roof) is completed, the crane is moved and the rainproof structure 10 is moved along with the crane.

[0110] In the rainproof structure 10, the first vertical rod 16, which is shorter in vertical dimension than the second vertical rod 17, is connected to the first connecting rod 33, the third connecting rod 36, and the fifth connecting rod 39, and the second vertical rod 17, which is longer in vertical dimension than the first vertical rod 16, is connected to the second connecting rod 34, the fourth connecting rod 37, and the sixth connecting rod 40. When the tip of the lifting rope 43 of the crane (lifting mechanism) is connected to the first to fourth connecting parts 21a to 21d and the horizontal lifting member 20 connected to the first and second vertical rods 16, 17 is lifted into the air by the lifting rope 43 of the crane, the rainproof sheet 12 is located above (directly above) the wooden prefabricated house 44 (assembly), and the first to third inclined rods 32, 35, and 38 are inclined downward from the third frame rod 27c (first side edge) of the frame 11 toward the fourth frame rod 27d (second side edge), Furthermore, the rainproof sheet 12 slopes downward from the third frame rod 27c (first side edge) of the frame 11 toward the fourth frame rod 27d (second side edge), and rainwater that falls on the rainproof sheet 12 flows over the rainproof sheet 12 from the third frame rod 27c (first side edge) of the frame 11 toward the fourth frame rod 27d (second side edge). Therefore, the rainproof sheet 12 can protect the wooden prefabricated house 44 (assembly) from rain when it rains, and the rainproof sheet 12 (rainproof structure 10) located directly above (above) the wooden prefabricated house 44 prevents the wooden prefabricated house 44 from getting wet, and installation (construction) work can be carried out to install the wooden unit house 45, which is made up of orthogonal laminated ceiling boards 46 and orthogonal laminated floor boards 47 made from CLT and wooden wall panels 48a to 48c made from two-by-four lumber, at the facility location while being protected from rain.

[0111] After the wooden prefabricated house 44 (assembly) has been moved from a predetermined location to the facility location and lowered to the facility location, the rainproof structure 10 can be installed by blocking the first to sixth openings 22a to 22f with the first to sixth auxiliary-auxiliary rainproof sheets 26a to 26f, thereby preventing rainwater from flowing downward through the first to sixth openings 22a to 22f, and positioning the rainproof structure 10 directly above (above) the wooden prefabricated house 44. This allows the wooden unit house 45, consisting of orthogonal laminated ceiling panels 46 and orthogonal laminated floor panels 47 made from CLT and wooden wall panels 48a to 48c made from two-by-four lumber, to be installed at the facility location while being protected from rain.
