Description

[Technical Field]

[0001] The present invention relates to a method for repairing a building and a repair structure used for repairing a building. [Background technology]

[0002] A scaffolding protection sheet structure described in Patent Document 1 has been known as a repair structure used in repairing buildings. The scaffolding protection sheet structure includes a scaffolding protection sheet structure that covers the outer surface of a scaffolding structure that is arranged to surround the periphery of a building. The outer surface of the scaffolding protection sheet structure is printed with advertising media. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3217936 Summary of the Invention [Problem to be solved by the invention]

[0004] In repair work using the scaffolding curing sheet structure and scaffolding structure described in Patent Document 1, the scaffolding is arranged to surround the entire periphery of the building, so the work of setting up and removing the scaffolding takes a lot of time and the scaffolding remains around the building for a long time. The presence of scaffolding around the building can, for example, give a sense of oppression to the residents and users of the building, and the psychological burden of the repair work on the residents and users increases.

[0005] Therefore, an object of the present invention is to provide a building repair method and a repair structure that can reduce the psychological burden placed on residents and users during building repairs. [Means for solving the problem]

[0006] The building repair method of the present invention is a building repair method for repairing a building that has a plurality of open spaces arranged in a vertical direction, each extending along at least a portion of the outer surface, open to the outside, and allowing people to move inside, and comprises an interior construction process in which repair work is carried out in the open spaces; a mobile means installation process in which, after the interior construction process is completed, a mobile means has a lifting platform that can move at least vertically along the open surface, which is the portion of the outer surface along which the open spaces extend circumferentially; an exterior construction process in which workers are placed on the lifting platform and repair work is carried out on the open surface or the open spaces; and a mobile means removal process in which the mobile means is removed.

[0007] With this configuration, the exterior construction work is carried out using a moving means with a lifting platform that can move up and down, which reduces the amount of temporary scaffolding that needs to be installed outside the open space during repair work, and because the moving means is installed after the interior construction work is completed, the time required for the moving means to be installed can be shortened, thereby reducing the psychological burden on residents and users.

[0008] In addition, the outer surface of the building comprises the open surface and a closed surface which is a portion where the open space is not provided in the circumferential direction, and comprises a scaffolding installation process for installing temporary scaffolding on the outside of the closed surface, a scaffolding construction process for carrying out repair work on the closed surface using the temporary scaffolding, and a scaffolding removal process for removing the temporary scaffolding, and the mobile means installation process can be carried out after the scaffolding installation process, and the mobile means removal process can be carried out before the scaffolding removal process.

[0009] With this configuration, the transportation means is installed after the temporary scaffolding is set up, and the temporary scaffolding is removed after the transportation means is removed, so the time required for the transportation means to be set up on the outside of the opening surface can be shortened, thereby reducing the psychological burden on residents and users.

[0010] In addition, the outer surface of the building may comprise the open surface and a closed surface which is a circumferential portion where the open space is not provided, and may comprise a scaffolding installation process for installing a temporary scaffold having a scaffolding main body located outside the closed surface and a connecting scaffolding extending from the scaffolding main body to the open space, a scaffolding construction process for performing repair work on the closed surface using the scaffolding main body, and a scaffolding removal process for removing the temporary scaffolding.

[0011] With this configuration, the scaffolding body and the connecting scaffold are installed as temporary scaffolding, so that workers can move between the scaffolding body and the open space. Therefore, even if the temporary scaffolding is not installed outside the opening surface, workers can move around the building in the circumferential direction along the scaffolding body and the open space, so that the installation range of the temporary scaffolding can be restricted without impairing workability.

[0012] The repair structure of the present invention is a repair structure used to repair a building that has a plurality of open spaces arranged vertically, extending along at least a portion of the outer surface and open to the outside, within which people can move, and is equipped with a moving means having a lifting platform that can move at least vertically along the open surface, which is the portion of the outer surface where the open spaces extend circumferentially, a scaffolding main body located outside the closed surface, which is the portion of the outer surface where the open spaces are not provided circumferentially, and a connecting scaffolding extending from the scaffolding main body to the open spaces.

[0013] With this configuration, the temporary scaffolding is placed on the outside of the closed surface, and the lifting platform is placed on the outside of the open surface, so the area of ​​the outside of the open space that is covered can be reduced, and the connecting scaffolding allows workers to move around the building along the scaffolding body and the open space. This prevents impairment of workability and reduces the psychological burden on residents and users. [Effects of the Invention]

[0014] According to the present invention, a building repair method and a repair structure can be obtained that can reduce the psychological burden placed on residents and users during building repairs. [Brief explanation of the drawings]

[0016] A repair method for a building M and a repair structure 7 according to one embodiment of the present invention will be described with reference to Figures 1 to 9. For ease of explanation, the up-down direction, left-right direction, and depth direction will be described based on the directions shown in Figures 1 and 2.

[0017] First, the method for repairing a building M according to this embodiment and the building M to which the repair structure 7 is applied will be described with reference to FIGS.

[0018] Building M is a structure, such as an apartment building or office building, that has multiple floors (for example, 4 to 20 floors) on the ground floor and is equipped with elevators 111 and stairs 112 for moving between floors. As shown in FIG. 2, building M has multiple rooms as private sections on each floor, and in this embodiment, each room functions as a dwelling unit. Building M in this embodiment has multiple rooms (for example, four rooms) arranged side by side in the left-right direction, and is equipped with corridors 11 and balconies 12 that extend outside each room along the line in which the rooms are arranged (left-right direction).

[0019] The corridors 11 and balconies 12 are arranged on each floor, and the corridors 11 and balconies 12 on each floor are arranged side by side in the vertical direction. The elevators 111 and staircases 112 are arranged to connect the corridors 11 arranged side by side in the vertical direction. Specifically, the elevators 111 and staircases 112 are arranged to protrude outward (opposite the living rooms) from the corridors 11. In this embodiment, the elevators 111 and staircases 112 are arranged at one end (left end) of the corridor 11 in the extension direction, and the staircases 112 are arranged at the other end (right end) of the corridor 11 in the extension direction. In addition, partitions 121 are arranged in the balcony 12 midway in the extension direction (left-right direction), and the partitions 121 form multiple areas on the balcony 12 corresponding to the living rooms. The partitions 121 arranged on the balcony 12 are configured to be removable, and by removing them, people can move left and right between multiple areas inside the balcony 12. Such corridors 11 and balconies 12 are open spaces S that are open to the outside of the building and allow people to move around inside.

[0020] The outer surface of such a building M comprises an open surface A (in this embodiment, the front and back surfaces) which is the portion where the open space S (corridors 11 and balconies 12) extends in the circumferential direction, and a closed surface B (in this embodiment, the left and right surfaces) which is the portion where the open space S is not provided in the circumferential direction. The closed surfaces B are located on one end side and the other end side in the extension direction of the open space S.

[0021] A repair method and repair structure 7 applicable to the above-described building M will now be described. For convenience of explanation, the repair method will be explained separately for construction on the balcony 12 side of the closed surface B and the opening surface A (hereinafter referred to as "balcony-side construction"), and construction on the corridor 11 side of the opening surface A (hereinafter referred to as "corridor-side construction"). In implementing the present invention, as explained below, construction can be carried out separately on the corridor 11 side and the balcony 12 side, or construction can be carried out on the corridor 11 side and the balcony 12 side together. Furthermore, if there is no need to repair the entire building M, construction can be carried out on only one of the corridor 11 side and the balcony 12 side.

[0022] Construction on the balcony side will be described with reference to Figures 3 to 7. Construction on the balcony side involves (1) a scaffolding installation process, (2) an interior construction preparation process, (3) an interior construction process, (4) a transportation means installation process, (5-1) an exterior construction process and (5-2) a scaffolding installation process, (6) a transportation means removal process, (7) an interior restoration process, and (8) a scaffolding removal process.

[0023] As shown in FIG. 3, (1) the scaffolding installation process is a process of installing temporary scaffolding 2 around the building M. The temporary scaffolding 2 is a structure that is assembled from the ground and has multiple stories lined up in the vertical direction, and is configured so that people can move around on each story using it as scaffolding. Specifically, the temporary scaffolding 2 includes a framework (not shown) that is assembled from the ground and plate-shaped scaffolding sections 2A that are fixed to the framework, and the scaffolding sections 2A are lined up in the vertical direction to form stories. In this embodiment, the scaffolding sections 2A are configured by arranging multiple plate-shaped bodies horizontally. In this embodiment, the temporary scaffolding 2 is arranged so that the stories of the temporary scaffolding 2 and the stories of the building M match. In addition, the temporary scaffolding 2 includes temporary stairs for moving up and down between the scaffolding sections 2A on different stories. Such temporary scaffolding 2 comprises a scaffolding body 22 arranged outside the closing surface B, a connecting scaffolding 23 extending from the scaffolding body 22 to the open space S, and a protruding part scaffolding 24 connected to the scaffolding body 22 and extending to the outside of the protruding part of the opening surface A. The scaffolding body 22 in this embodiment is configured to extend linearly along the closing surface B.

[0024] In the scaffolding installation process, the scaffolding section 2A is arranged to extend along the closing surface B to form the scaffolding main body 22, and the scaffolding section 2A is arranged to connect the end of the formed scaffolding main body 22 in the extension direction to the open space S (e.g., the balcony 12) to form the connecting scaffolding 23. The scaffolding main body 22 is installed so that it extends beyond the end of the closing surface B in the depth direction (to the front side in this embodiment). The connecting scaffolding 23 is installed for a length necessary and sufficient for a person to move from the scaffolding main body 22 to the open space S, and in this embodiment, one span (e.g., one plate-like body constituting the scaffolding section 2A) of the scaffolding section 2A is arranged from the end on the front side in the extension direction of the scaffolding main body 22 toward the open surface A (the outside of the balcony 12). In addition, in the scaffolding installation process, the temporary scaffolding 2 is installed on a part of the outside of the open surface A. Specifically, for an opening surface A having a protruding portion protruding outward (for example, a staircase 112 or an elevator 111 portion), the protruding scaffolding 24 is installed so as to extend from an end of the opening surface A in the extension direction of the open space S (specifically, the end closest to the protruding portion among both left and right ends of the opening surface A) to the protruding portion. Specifically, the protruding scaffolding 24 is installed from one end of the opening surface A on the corridor 11 side to the staircase 112 arranged at that end, and from the other end of the opening surface A on the corridor 11 side to the staircase 112 arranged at the other end. The protruding scaffolding 24 of this embodiment is installed so as to cover the entire outer periphery of the protruding portion. The scaffolding main body 22 and the protruding scaffolding 24 are configured so that people can move between them.

[0025] As shown in Figures 4 to 6, (2) the internal construction preparation process is a process of preparing for repair work in the open space S (inside the balcony 12). In the internal construction preparation process, the balcony 12 is made available for workers to move around, and preparations are made to prevent materials, tools, and workers from falling from the balcony 12. Specifically, the internal construction preparation process involves removing the partition board 121, installing the anti-scattering sheet 3, and installing the hook portion 4 for fall arrest equipment.

[0026] Removal of the partition board 121 is a process of removing the partition board 121 arranged on the balcony 12 to enable people to move around inside the balcony 12. In this embodiment, after the partition board 121 is removed, an openable and closable temporary partition 5 is arranged, and by opening the temporary partition 5, people can move around between multiple areas inside the balcony 12.

[0027] As shown in Figures 4 and 5, when installing the shatterproof sheet 3, the portion of the balcony 12 that is open to the surrounding space of the building M is covered with the shatterproof sheet 3 in a direction along the opening surface A (e.g., vertically). The shatterproof sheet 3 covers the exterior of the building M, including the balcony 12. Covering the balcony 12 with the shatterproof sheet 3 prevents construction materials, tools, etc. from scattering and falling outside the balcony 12, even if wind enters the balcony 12 or a worker's hand slips. The shatterproof sheet 3 is, for example, a mesh-like sheet. The mesh-like structure allows wind to pass through and reduces flapping of the shatterproof sheet 3. Furthermore, the mesh-like structure does not completely block light, thereby reducing discomfort to residents in the room. The shatterproof sheet 3 has an opening 31 that can be opened and closed in the thickness direction of the sheet to allow workers to pass through. This opening 31 is configured to be freely opened and closed using a zipper 32. Note that other means for opening and closing the opening of the entrance / exit 31, such as buttons, snaps, or hook-and-loop fasteners, may be used instead of the zipper 32. However, from the viewpoints of ease of opening and closing and wind resistance (the likelihood of it opening unexpectedly due to wind), it is preferable to use the zipper 32. Furthermore, from the viewpoint of ease of operation, it is preferable to provide handles for the zipper 32 on both the front and back of the shatterproof sheet 3. A shatterproof sheet 3 having such an entrance / exit 31 makes it easy for materials and workers to enter and exit the balcony 12 (for example, for carrying in materials using a loading platform or crane).

[0028] As shown in Figures 4 and 6, the fall arrest device hooking section 4 is installed inside the balcony 12, where a fall arrest device (specifically, a full harness-type fall arrest device, formerly known as a "safety belt") worn by a worker can be hung. The fall arrest device hooking section 4 includes a support section 41 fixed to the building M and an elongated member 42 supported by the support section 41 and arranged along the left-right direction of the open section of the balcony 12. With this configuration, the worker can move along the elongated member 42 with the hook of the fall arrest device hung on the elongated member 42. This allows for a wider range of movement for workers working inside the balcony 12. The support section 41 is, for example, an eyebolt embedded in the frame of the building M at the upper part of the balcony 12. The eyebolts are provided in at least two locations. The eyebolts are provided, for example, at intervals of 2 m, to ensure that the long body 42 properly supports the fall arrest device. The long body 42 is, for example, a coated wire or rope. Furthermore, to provide the long body 42 with an appropriate tension to support the hung fall arrest device, a turnbuckle 43 is provided between the support part 41 and the long body 42, or between the long bodies 42 when two or more long bodies 42 are provided. After the repair work is completed, holes remain where the support parts 41 (eyebolts) were installed. To deal with these holes, for example, rust-resistant bolts made of stainless steel or the like can be installed in the holes, or plastic caps can be attached to the holes. Alternatively, the holes can be filled with mortar or the like and then painted. Furthermore, the support parts 41 and the long body 42 can be left attached even after the repair work is completed in preparation for the next repair work.

[0029] (3) The internal construction process is a process of carrying out repair work within the open space S. Specifically, workers clean and reupholster the ceiling and floor inside the balcony 12, and perform maintenance and inspection of the equipment installed on the balcony 12.

[0030] As shown in FIG. 7 , (4) the transportation means installation step is a step of installing transportation means 6 having a lifting platform 61 that can move up and down along the open surface A along which the open space S (balcony 12) extends. Furthermore, in the transportation means installation step of this embodiment, in addition to installing the transportation means 6, it is also made possible for people to move between the transportation means 6 and the open space S. In this embodiment, in addition to installing the transportation means 6, the shatterproof sheet 3 provided on the balcony 12 is removed. Here, when the shatterproof sheet 3 is removed, the open space S is open to the outside except for the floor where the lifting platform 61 is stopped. This reduces the sense of oppression felt by residents and users.

[0031] The transportation means 6 in this embodiment is a gondola equipped with a lifting platform 61 that moves up and down while carrying people or materials for work, and a wire (not shown) for moving the lifting platform 61. The transportation means 6 is also configured so that the lifting platform 61 can stop at a position corresponding to each floor of the building M, and the lifting platform 61 can move left and right across the entire area of ​​the balcony 12. However, this configuration is not limited to this, and the transportation means 6 can also be configured as a lift climber that has a lifting platform 61 that can move only up and down and has a width that allows the worker to open left and right and move across the entire area of ​​the surface A. The lifting platform 61 can also be configured to move along a rail instead of a wire.

[0032] Here, the installed temporary scaffolding 2, the moving means 6, the temporary partition 5, and the fall arrest device hook portion 4 constitute a repair structure 7. Such a repair structure 7 makes it easy to carry out the repair work described below.

[0033] (5-1) The external construction process is a process in which workers are placed on a lifting platform 61 and moved along the opening surface A to carry out repair work on the opening surface A or the open space S. Specifically, in the external construction process, the exterior walls on the opening surface A are cleaned, painted, reupholstered, etc. Furthermore, in the external construction process, work is carried out on parts of the open space S where repair work cannot be performed from within the open space S (for example, the outside of the balustrade arranged on the balcony 12).

[0034] (5-2) The scaffolding construction process is a process in which a worker moves the temporary scaffolding 2 along the closing surface B to perform repair work on the closing surface B. Also, in the scaffolding construction process, for the opening surface A having a protruding portion (for example, a staircase 112 or an elevator 111 portion) that protrudes outward, repair work is performed from the end of the opening surface A in the extension direction of the open space S (specifically, the end closest to the protruding portion among both left and right ends of the opening surface A) to the outside of the protruding portion. Specifically, in the scaffolding construction process, the exterior wall of the closing surface B is cleaned, painted, reupholstered, etc. Also, in the scaffolding movement process, a worker can move from the temporary scaffolding 2 to the open space S via the connecting scaffolding 23. For example, the worker can move from the temporary scaffolding 2 arranged outside the closing surface B located on one side of the open space S through the open space S to the temporary scaffolding 2 arranged outside the closing surface B located on the other side. The scaffolding construction process can be carried out before the (3) internal construction process, (4) transportation means installation process, or (5-1) external construction process, or can be carried out after the (6) transportation means removal process.

[0035] (6) The transportation means removal process is a process of removing the installed transportation means 6. The transportation means removal process is performed after the (5-1) external construction process is completed.

[0036] (7) The interior restoration process is a process of carrying out construction to restore the open space S to its original state. Specifically, this process involves installing a partition board 121 and removing the hooking portion 4 for the fall arrest device. The installation of the partition board 121 is a process of removing the temporary partition 5 installed for the repair work and reinstalling the partition board 121. Note that if the partition board 121 installed before the repair work is unsuitable for reuse due to deterioration or the like, a new partition board 121 can also be installed. The removal of the hooking portion 4 for the fall arrest device is a process of removing the support portion 41 and the elongated body 42 installed in the open space S and filling in any holes created by the removal. Note that the hooking portion 4 for the fall arrest device can also be left in place without being removed.

[0037] (8) The scaffolding removal process is a process of removing the temporary scaffolding 2. In the scaffolding removal process, the assembled temporary scaffolding 2 is disassembled and removed.

[0038] The balcony side construction is now complete. Next, the corridor side construction will be explained with reference to Figures 8 and 9.

[0039] The corridor-side construction involves the following steps: (1) scaffolding installation, (2) interior construction preparation, (3) interior construction, (4) transportation installation, (5-1) exterior construction, (6) transportation removal, (7) interior restoration, and (8) scaffolding removal. The same parts of each step as those in the balcony-side construction will be omitted, and only the differences will be explained. In actual construction, the corridor-side construction and balcony-side construction are carried out as a single piece of work, with the corridor-side construction taking place between the (1) scaffolding installation step and the (8) scaffolding removal step of the balcony-side construction described above. In other words, in the corridor-side construction of this embodiment, the corridor-side construction steps (2) interior construction preparation to (7) interior restoration are carried out before the temporary scaffolding 2 is removed in the (8) scaffolding removal step of the balcony-side construction described above. Therefore, temporary scaffolding 2 is illustrated in Figures 8 and 9.

[0040] As shown in Figure 8, (2) the internal construction preparation process is a process of preparing for repair work in the open space S (inside the corridor 11). In the internal construction preparation process, a scattering prevention sheet 3 is installed on the outside of the corridor 11, and a fall arrest device hook 4 is installed so as to extend along the corridor 11. Note that since no partition board 121 is installed in the corridor 11, the partition board 121 is not removed.

[0041] (3) The internal construction process is a process of carrying out repair work within the open space S. Specifically, workers clean and reupholster the ceiling and floor inside the corridor 11, and perform maintenance and inspection of the equipment installed in the corridor 11.

[0042] As shown in FIG. 9, (4) the transportation means installation process involves installing transportation means 6 having a platform 61 that can move up and down along the open surface A where the open space S (corridor 11) extends, and removing the anti-scattering sheet 3. In the corridor-side construction, the transportation means 6 is positioned so that the platform 61 is located between a protruding portion located at one end of the corridor 11 and a protruding portion located at the other end. The transportation means 6 is configured so that the platform 61 can stop at a position corresponding to each floor of the building M and can move left and right between the protruding portion located at one end of the corridor 11 and the protruding portion located at the other end. However, the configuration is not limited to this. The platform 61 can also be configured as a lift climber that has a platform 61 that can move only up and down and is wide enough to allow a worker to move left and right between the protruding portion located at one end of the corridor 11 and the protruding portion located at the other end.

[0043] (5-1) The external construction process is a process in which workers are placed on the lifting platform 61 and moved along the opening surface A to perform repair work on the opening surface A or the open space S. In the external construction process for corridor-side construction, repair work is performed on the portion of the opening surface A between the protruding portion located on one end of the corridor 11 and the protruding portion located on the other end. Note that the portion of the opening surface A that is being constructed on the corridor side (the end and protruding portion of the corridor 11) is repaired in the scaffolding construction process described above. That is, in the corridor-side construction of this embodiment, repair work is performed on the portion of the opening surface A on the corridor 11 side between the protruding portions (stairs 112). In this embodiment, construction is performed on a portion of the opening surface A on the corridor 11 side using temporary scaffolding 2. However, compared to when construction is performed entirely using temporary scaffolding 2, the area of ​​the open space S that is covered can be reduced, thereby reducing the psychological burden on residents and users.

[0044] (6) The transportation means removal process is a process of removing the installed transportation means 6. The transportation means removal process is performed after the (5-1) external construction process is completed.

[0045] (7) The interior restoration process is a process of carrying out construction to restore the open space S to its original state. Specifically, the fall arrest device hook portion 4 is removed, and the partition plate 121 is not installed.

[0046] This completes the corridor side construction.

[0047] According to the above-described repair method for a building M, the exterior construction process is carried out using a moving means 6 having a lifting platform 61 that can move up and down, so the area outside the open space S that needs to be covered with temporary scaffolding 2 or the like during repair work can be reduced, and since the moving means 6 is installed after the interior construction process is completed, the period for installing the moving means 6 can be shortened. This reduces the psychological burden on residents and users.

[0048] Furthermore, with the repair structure 7 as described above, the temporary scaffolding 2 is placed outside the closing surface B, and the lifting platform 61 is placed outside the opening surface A, so the area of ​​the outside of the open space S that is covered can be reduced, and the connecting scaffolding 23 allows workers to move around the building M in the circumferential direction along the scaffolding body 22 and the open space S. This makes it possible to reduce the psychological burden on residents and users while preventing impairment of workability.

[0049] The above describes an embodiment of the present invention using an example, but the present invention is not limited to the above embodiment, and various modifications can be made within the scope that does not deviate from the gist of the present invention.

[0050] For example, although the present invention has been described in connection with an example in which the building M to which it is applied is an apartment building, it is not limited to this and can also be applied to buildings M such as office buildings. Furthermore, although the present invention has been described in connection with an example in which the building M has a corridor 11 and a balcony 12 as open spaces S, it is not limited to this configuration and the present invention can also be applied to a building M having only one of the corridor 11 or the balcony 12 as open spaces S. Furthermore, even when the present invention is applied to a building M having both a corridor 11 and a balcony 12 as open spaces S, it is also possible to apply the present repair method or repair structure 7 to only one of the corridor 11 and the balcony 12.

[0051] Furthermore, the order of each process is not limited to the order shown in the example, and the order can be changed as appropriate, and some processes (for example, (5-1) external construction process and (5-2) scaffolding construction process) can be performed simultaneously.

[0052] Furthermore, although the example has been explained in which the corridor side construction and the balcony side construction are carried out separately, the construction order can be reversed, or they can be carried out simultaneously or partially overlapping. When carried out simultaneously, the same process in each construction (for example, the (3) interior construction process for the corridor side construction and the (3) interior construction process for the balcony side construction) can be carried out at the same time.
