Description

[Technical field]

[0001] The present invention relates to a moving jig and a construction method using the moving jig, and more particularly to a moving jig for moving a heavy object on a floor and a construction method using the moving jig. [Background technology]

[0002] Conventionally, in order to improve the efficiency of construction work at a construction site, a construction method has been known in which a heavy interior unit (e.g., a modular bath) is preassembled in a factory, the assembled interior unit is transported to the construction site, the transported interior unit is lifted by a sling hooked to a lifting device, and the lifted interior unit is installed in a designated position inside the building's structure. At this time, in the process of installing the interior unit in a predetermined position, depending on the progress of the construction or the absence of a professional contractor to install the interior unit, it may not be possible to install the interior unit in the predetermined position as it is. In such a case, it is necessary to temporarily place the lifted interior unit in another position inside the structure, and then move the temporarily placed interior unit to the predetermined position inside the structure after the interior unit can be installed. For this reason, a moving jig (transporting jig) is known that can temporarily place an interior unit and move the temporarily placed interior unit while lifting it off the floor (see, for example, Patent Document 1).

[0003] The device for moving the spatial unit described in Patent Document 1 is mainly composed of a number of hydraulic jacks that are removably fixed to a base frame at the lower end of the spatial unit and raise and lower the spatial unit, and a number of mobile carts that are inserted into a lower position of the spatial unit and support the spatial unit from below. With the above-described configuration, the spatial unit can be temporarily placed in a state where it is suspended above the floor, and the temporarily placed spatial unit can be moved to a predetermined position while being suspended. In addition, by raising the spatial unit with a hydraulic jack, the mobile trolley can be inserted into a position below the spatial unit. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2000-320011 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the moving device as disclosed in Patent Document 1, the moving cart is inserted directly under the heavy object and supports the base frame of the heavy object from below, but the base frame is not held in a pinched manner. Therefore, if the heavy object loosens, there is a risk that the heavy object cannot be held properly. On the other hand, if the base frame is pinched from below, it is difficult to remove it from the heavy object without a hydraulic jack. Therefore, there has been a demand for a moving jig that can stably hold a heavy object and can be easily detached from the heavy object.

[0006] In addition, there has been a demand for a moving tool that can suitably move a heavy interior unit while keeping it lifted off the floor, rather than using a complex moving device as in Patent Document 1.

[0007] The present invention has been made in consideration of the above-mentioned problems, and an object of the present invention is to provide a moving jig that can stably hold a heavy object and can be easily detached from the heavy object, and a construction method using the moving jig. Another object of the present invention is to provide a moving jig and a construction method using the moving jig that have a simple configuration and can temporarily place a heavy interior unit in a floating state above the floor and can move the interior unit in an appropriate manner. [Means for solving the problem]

[0008] The above problem is solved by the moving jig of the present invention, which is a moving jig for moving a heavy object on a floor, A main body portion that serves as a main body of the moving jig; A caster part for moving on a floor; Main unit and a switching portion that switches the holding portion between a first state and a second state, the holding portion having a bottom wall portion that supports the held portion from below, and a first side wall portion and a second side wall portion that protrude upward from the bottom wall portion and sandwich the held portion, and when the holding portion is in the first state, the first side wall portion and the second side wall portion are provided at a position where they sandwich the held portion, and when the holding portion is in the second state, at least one of the first side wall portion and the second side wall portion is provided at a position moved from the position where they sandwich the held portion. The caster portion is provided at a lower position than the main body portion, and a plurality of casters are provided so as to surround the holding portion in a top view. This problem is solved by: With the above-described configuration, it is possible to realize a moving jig that can stably hold a heavy object and can be easily detached from the heavy object. More specifically, the moving jig includes a switching unit that switches the holding unit between a first state and a second state. Therefore, when the holding unit is in the first state, the moving jig can hold the heavy object by pinching it from below. On the other hand, by switching the holding unit from the first state to the second state, the moving jig can also be easily detached from the heavy object. Furthermore, with the above-described configuration, a heavy object can be temporarily placed in a state where it is lifted off the floor with a simple structure, and the temporarily placed interior unit can be moved conveniently.

[0009] The above problem is solved by a moving jig of the present invention, which is a moving jig for moving a heavy object on a floor, the moving jig comprising: caster parts for moving on the floor; a holding part provided at a position higher than the caster parts for holding a held part provided on the heavy object by sandwiching it from below; and a switching part for switching the holding part between a first state and a second state, the holding part having a bottom wall part supporting the held part from below, and a first side wall part and a second side wall part protruding upward from the bottom wall part and sandwiching the held part, and when the holding part is in the first state, the first side wall part and the second side wall part support the held part from below. The problem is solved by the following: the switching portion is provided at a position where it clamps the holding portion, and when the holding portion is in the second state, at least one of the first side wall portion and the second side wall portion is provided at a position moved from the position where it clamps the held portion, the switching portion is attached to the holding portion and connects the first side wall portion and the second side wall portion so that they can each rotate relative to the bottom wall portion, and when the holding portion is in the second state, the first side wall portion and the second side wall portion are each provided at a position rotated downward from the position where they clamp the held portion, and a substantially flat surface is formed between the bottom wall portion and the first side wall portion and the second side wall portion. Even with the above configuration, the holding part can be easily switched by, for example, attaching a plurality of hinge mechanisms to the holding part. In addition, the moving jig in the second state can be easily removed by pulling it out from the side. As described above, when the holding part is in the second state, a substantially flat surface is formed by the bottom wall part and the first and second side walls, so that the heavy object (interior unit) can be supported even if the lower end of the heavy object is a substantially flat surface. In more detail, depending on the type of heavy object (interior unit), there may be cases where the held part (base frame) is not attached to the lower end of the heavy object, making it impossible to clamp the held part. In such cases, the heavy object can be favorably supported by switching the moving jig (holding part) to the second state.

[0010] The above problem is solved by a moving jig of the present invention, which is a moving jig for moving a heavy object across a floor, the moving jig comprising: a main body portion that is a main body of the moving jig; caster portions for moving across the floor; a holding portion that is provided above the caster portions and is for holding a held portion provided on the heavy object by sandwiching it from below; and a switching portion that switches the holding portion between a first state and a second state, the holding portion having a bottom wall portion that supports the held portion from below, and first and second side wall portions that protrude upward from the bottom wall portion and sandwich the held portion, and when the holding portion is in the first state, the first and second side wall portions sandwich the held portion. The problem is solved by the following: when the holding portion is in the second state, at least one of the first side wall portion and the second side wall portion is disposed at a position moved from the position where it clamps the held portion, and when the holding portion is in the second state, the moving jig comprises a height adjustment member that connects the main body portion and the holding portion and is attached in a state where the height position of the holding portion can be changed relative to the main body portion, and the height adjustment member is assembled through an assembly hole provided in the main body portion, and has a bolt that is long in the vertical direction and a nut that is screwed onto a shaft portion of the bolt, and is configured so that the height position of the holding portion can be changed by adjusting the screwing positions of the bolt and the nut. With the above-mentioned configuration, the height of the holding part can be adjusted with a simple configuration without using a hydraulic jack, etc., as in the past. By providing the height adjustment function of the holding part, it becomes easier to remove the moving jig from the heavy object. In more detail, when the moving jig is pulled out sideways from the held part (base frame) of the heavy object, the height of the holding part can be lowered somewhat as necessary to make it easier to pull out the moving jig. If the heavy object is supported on the floor by the legs at its bottom, the moving jig can be pulled out even more easily.

[0011] In this case, the switching portion is attached to the holding portion and connects the first side wall portion so as to be rotatable relative to the bottom wall portion, and is preferably provided at a position where the first side wall portion has rotated downward from the position where it clamps the held portion when the holding portion is in the second state. With the above configuration, for example, by attaching a hinge mechanism to the holding part, the first side wall of the holding part can be easily switched from the first state to the second state. Then, the moving jig in the second state can be easily removed by pulling it out sideways from the held part of the heavy object.

[0012] In this case, it is preferable that the movable jig comprises a main body portion which forms the main body of the movable jig, and a regulating member which is attached to the main body portion or the holding portion and moves between a regulating position which regulating the holding portion in the first state and a deregulating position which allows the holding portion to be switched from the first state to the second state. With the above configuration, the restricting member restricts the holding portion to remain in the first state, so that the moving jig can hold the heavy object more stably. In other words, it is possible to prevent the holding portion from unintentionally switching from the first state to the second state.

[0014] The problem is also solved by: Moving heavy objects across the floor A construction method using a moving jig, comprising: The moving jig has a caster portion, a holding portion that holds a held portion provided on the heavy object so as to sandwich it from below, and a switching portion that switches the holding portion between a first state and a second state, the holding portion has a bottom wall portion that supports the held portion from below, and a first side wall portion and a second side wall portion that protrude upward from the bottom wall portion and sandwich the held portion, when the holding portion is in the first state, the first side wall portion and the second side wall portion are provided at a position where they sandwich the held portion, and when the holding portion is in the second state, at least one of the first side wall portion and the second side wall portion is provided at a position moved from the position where they sandwich the held portion, and the construction method includes: weight Things assemble set The assembly process and the assembled heavy goods Deliver to the construction site transportation The step of introducing the above-mentioned heavy goods is lifted by a sling member hooked to a lifting device Hanging A lifting step and the lifted heavy goods is temporarily placed inside the building's framework, suspended above the floor. tentative A step of placing the temporarily placed heavy goods Move to a designated position inside the structure Transfer a moving step; heavy goods Install in a designated position inside the structure.

Effect of the Invention

[0015] According to the moving jig and the construction method using the moving jig of the present invention, a heavy object can be stably held and can be easily removed from the heavy object. In addition, with a simple configuration, it is possible to temporarily place the heavy interior unit in a state where it is raised above the floor, and to move the interior unit in an appropriate manner. Furthermore, it becomes possible to suitably install the interior unit preassembled in a factory inside the framework of a building. [Brief description of the drawings]

[0017] Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 11A and 11B. This embodiment relates to an invention of a moving jig for moving an interior unit across a floor, the moving jig comprising a caster section that moves across the floor, a holding section that holds a base frame provided on the bottom surface of the interior unit by clamping it from below, and a switching section that switches the holding section between a "first state" and a "second state", the holding section having a bottom wall section that supports the base frame from below, and a first side wall section and a second side wall section that clamp the base frame, the first side wall section and the second side wall section being provided in a position that clamps the base frame when the holding section is in the "first state", and the first side wall section being provided in a position moved from the position that clamps the base frame when the holding section is in the "second state". The present invention also relates to a construction method using the moving jig.

[0018] The construction system S including the mobile jig 1 of this embodiment is a construction system used to lift an interior unit U preassembled in a factory using a lifting device S1 and install it directly at a designated position inside the structure of a building, in order to streamline assembly and installation work at a construction site, as shown in Figures 1 to 3. More specifically, the construction system S includes a sling member S2 hooked to the lifting device S1, and a lifting balance S3 and a lifting jig S4 for holding the lifting position of the sling member S2, which are used when lifting the interior unit U with the lifting device S1. The construction system S also includes a moving jig 1, which is used when temporarily placing the lifted interior unit U inside the building in a state where it is suspended above the floor, and is also used when moving the temporarily placed interior unit U to a predetermined position inside the building.

[0019] As shown in Figures 1 to 3, the interior unit U is a unit that is assembled so that various facilities to be installed inside a building can be unitized and installed as is, and includes various unit items such as a unit bath, unit toilet, and unit kitchen. The interior unit U is mainly composed of a box-shaped unit body U1, a rectangular frame U2 attached to the bottom surface of the unit body U1, and a plurality of leg members U3 protruding downward from the bottom surface of the base frame U2. The interior unit U is covered from above with a sheet-like unit cover U4 from the process of transporting it from the factory to the construction site to the process of installing it inside the building.

[0020] The base frame U2 is formed from a long rectangular pipe member having a square cross section, and is a frame member for installing the interior unit U on the framework of a building. The base frame U2 also functions as a member for attaching the moving jig 1 when moving the interior unit U on the floor. As shown in Figs. 3 and 8A, the leg member U3 is a shaft-shaped leg member extending in the vertical direction, and is fixed onto a floor panel inside a building using an adhesive. The leg member U3 also functions as a member for attaching a lifting jig S3 when lifting the interior unit U. The unit cover U4 is a waterproof protective cover, and a cover opening / closing portion for enabling the interior unit U to be removed is formed on one end surface of the unit cover U4 in the width direction.

[0021] As shown in Figures 2 and 3, the moving jig 1 is used when temporarily placing the interior unit U in a state where it is raised above the floor, and is also used when moving the interior unit U on the floor, and is arranged at the four corners of the lower end of the interior unit U. More specifically, the moving jig 1 is detachably attached to the base frame U2 of the interior unit U, and can move while holding the interior unit U with the leg members U3 slightly raised above the floor F. In addition, the height position of the interior unit U can be adjusted.

[0022] As shown in Figures 4-7, the moving jig 1 is mainly composed of a main body section 10 which is the main body of the moving jig 1, a caster section 20 which is located below the main body section 10 and moves horizontally on the floor, a holding section 30 which is located above the main body section 10 and holds the base frame U2 of the interior unit U from below, a switching section 40 which is attached to the holding section 30 and switches the holding section 30 between a "first state" and a "second state", a regulating member 50 which is attached to the main body section 10 and regulates the holding section 30 in the "first state", and a height adjustment member 60 which connects the main body section 10 and the holding section 30 and is attached in a state in which the height position of the holding section 30 relative to the main body section 10 can be changed.

[0023] The main body 10 is a main body plate made of a triangular plate body and has a horizontal plane. The upper surface of the main body portion 10 is provided with an assembly hole 11 formed in the central portion of the main body portion 10 for assembling a height adjustment member 60, a plurality of mounting holes 12 formed in the corners of the main body portion 10 for attaching the caster portion 20, and an assembly hole 13 formed between two predetermined mounting holes 12 for assembling a regulating member 50.

[0024] As shown in FIGS. 4 and 5, the caster parts 20 are spherical rotating bodies that can freely change direction and rotate. A plurality of caster parts 20 are provided on the main body part 10 so as to surround the holding part 30. In detail, the three caster parts 20 are arranged at approximately equal intervals from the center of the holding part 30 in a plan view, and include a first caster part 20A, a second caster part 20B, and a third caster part 20C.

[0025] The caster section 20 is mainly composed of a caster axle 21 that is journaled through the mounting hole 12 of the main body section 10 and extends in the vertical direction, a caster body 22 that can rotate horizontally around the caster axle 21 relative to the main body section 10, an axle 23 that is journaled through the caster body 22 and extends in a direction perpendicular to the caster axle 21, and a spherical wheel 24 that can rotate around the axle 23 relative to the caster body 22. With the above-described configuration, the moving jig 1 can be freely moved on the floor by rotating the caster parts 20 while swiveling. The caster unit 20 may be a swivel caster, or a fixed caster (disk-shaped wheel) whose traveling direction is fixed in the front-rear direction.

[0026] As shown in Figs. 4 and 5, the holding portion 30 has a substantially U-shape, is formed from a plurality of plate-like members, and is a member that holds the base frame U2 of the interior unit U by sandwiching it from below. The holding part 30 is attached to the center of the main body part 10 in a top view, and is provided so as to protrude upward from the upper surface of the main body part 10 in a side view. Specifically, the holding part 30 is attached to the upper surface of the main body part 10 via a height adjustment member 60.

[0027] The holding portion 30 is attached to the upper end of the height adjustment member 60 and has a bottom wall portion 31 extending in a direction perpendicular to the height direction of the moving jig 1, a first side wall portion 32 and a second side wall portion 33 protruding upward from both ends of the width of the bottom wall portion 31, and a hollow portion 34 protruding downward from the center of the bottom surface of the bottom wall portion 31 and through which the height adjustment member 60 (height adjustment bolt 63) can be inserted. The holding portion 30 can hold the base frame U2 of the interior unit U by sandwiching it from below with the bottom wall portion 31, the first side wall portion 32, and the second side wall portion 33. The first side wall portion 32 is attached to the bottom wall portion 31 via a transition portion 40. On the other hand, the second side wall portion 33 and the hollow portion 34 are formed integrally with the bottom wall portion 31.

[0028] As shown in Figures 6A and 6B, the switching portion 40 is a hinge member that rotatably connects the first side wall portion 32 to the bottom wall portion 31, and can switch the holding portion 30 between a "first state (holding position)" and a "second state (detachable position)." The switching portions 40 are arranged at predetermined intervals in the longitudinal direction of the holding portion 30, and are arranged at positions that avoid the hollow portion 34 in the longitudinal direction.

[0029] Specifically, the switching section 40 is mainly composed of a fixed plate 41 attached to the bottom surface of the bottom wall section 31, a movable plate 42 attached to the outer surface of the first side wall section 32, and a pivot shaft 43 that rotatably connects the movable plate 42 to the fixed plate 41.

[0030] In the above configuration, when the holding portion 30 is in the “first state (holding position)” shown in FIG. 6A, the first side wall portion 32 and the second side wall portion 33 each protrude upward and are positioned to sandwich the base frame U2. 6B, the first side wall 32 is disposed at a position moved from the position where the base frame U2 is sandwiched. More specifically, the first side wall 32 is disposed at a position rotated downward from the position where the base frame U2 is sandwiched. When the holding portion 30 is in the "second state", the first side wall portion 32 extends so as to incline downward as it moves away from the bottom wall portion 31. This makes it easier to remove the holding portion 30 from the base frame U2.

[0031] As shown in Figures 6A and 6B, the regulating member 50 is attached so as to protrude upward from the main body 10, and is a member that moves between a "regulating position" that regulates the holding portion in a first state and a "release position" that allows the holding portion to be switched from the first state to the second state. The restricting member 50 is disposed between the first caster portion 20A and the second caster portion 20B adjacent to each other in a top view, and is disposed at a position opposite to the third caster portion 20C with respect to the central portion of the main body portion 10.

[0032] The regulating member 50 is mainly composed of a fixing nut 51 provided on the upper surface of the main body portion 10, and a regulating bolt 52 (wing bolt) that passes through the main body portion 10 (assembly hole 13) and is screwed into the fixing nut 51, protrudes upward from the main body portion 10, and can abut against the outer surface of the first side wall portion 32. The regulating bolt 52 is configured so that the height position can be changed by adjusting the screwing position with the fixing nut 51.

[0033] In the above configuration, when the restricting member 50 is in the “restricting position” shown in FIG. 6A, the restricting bolt 52 abuts against the outer surface of the first side wall portion 32, restricting the movement of the first side wall portion 32. When the restricting member 50 is in the "unrestricted position" shown in FIG. 6B, the restricting bolt 52 is disposed at a position lower than the holding portion 30, and the restriction on the movement of the first side wall portion 32 is released.

[0034] As shown in Figures 6A and 7, the height adjustment member 60 is mainly composed of fixing nuts 61, 62 provided on the top and bottom surfaces of the main body portion 10, and a height adjustment bolt 63 that passes through the main body portion 10 (assembly hole 11) and is screwed into the fixing nuts 61, 62, protrudes upward from the main body portion 10, and can abut against the holding portion 30. The hollow portion 34 of the holding portion 30 is attached to the upper end portion of the height adjustment bolt 63 .

[0035] In the above configuration, by adjusting the screwing position of the height adjustment bolt 63 relative to the fixing nuts 61, 62, the holding part 30 can be moved to a height position corresponding to the screwing position of the height adjustment bolt 63. In other words, the height position of the moving jig 1 can be appropriately adjusted.

[0036] With the above configuration, it is possible to realize a moving jig 1 that can be easily attached to the interior unit U, can stably hold the interior unit U, and can also be easily removed from the interior unit U. Specifically, as shown in Fig. 8A, by putting the moving jig 1 in the second state (detachable position), the moving jig 1 can be attached to the base frame U2 of the interior unit U from the side. Then, by switching the moving jig 1 from the second state to the first state (holding position), the moving jig 1 can hold the base frame U2 by sandwiching it from below. Thereafter, by switching the moving jig 1 from the first state to the second state, as shown in Fig. 8B, the moving jig 1 can be removed from the base frame U2.

[0037] <Construction method using a moving jig> Next, a method for constructing the interior unit U using the hoisting balance S3, the hoisting jig S4, and the moving jig 1 will be described with reference to FIG. First, the process begins with a "unit assembly process" (step S1) in which a worker (e.g., a manufacturer's installer) preassembles the interior unit U.

[0038] Thereafter, a worker carries in the assembled interior unit U to the construction site (step S2). At this time, the interior unit U is covered with the unit cover U4 and carried in by the truck with the waist belt wound around it.

[0039] Thereafter, a worker performs a "unit lifting step" in which the carried-in interior unit U is lifted by the sling member S2 hooked to the lifting device S1 (step S3). More specifically, in the unit lifting process, as shown in FIG. 1, the lifting position of the sling member S2 is maintained by a frame-shaped lifting balance S3 (step S3-1), a lifting jig S4 is hooked onto the leg member U3 of the interior unit U (step S3-2), and the lifting jig S4 is attached to the lower end of the sling member S2 (step S3-3), and then the interior unit U is lifted (step S3-4). The operations from step S3-1 to step S3-3 may be performed in any order.

[0040] Thereafter, a worker performs a "unit temporary placement step" in which the lifted interior unit U is temporarily placed inside the building framework in a state where it is suspended above the floor (step S4). More specifically, in the unit temporary placement process, as shown in FIG. 2, multiple moving jigs 1 are attached to the base frame U2 of the interior unit U (step S4-1), the interior unit U is temporarily placed in a suspended state above the floor (step S4-2), and the hanging jig S4 is removed from the interior unit U (step S4-3). The temporarily placed interior unit U is stored at another location inside the building for a predetermined period of time depending on the progress of the construction work, for example. Alternatively, the interior unit U is stored at another location inside the building until the manufacturer / constructor of the interior unit U arrives.

[0041] Thereafter, a worker performs a "unit moving step" in which the temporarily placed interior unit U is moved to a predetermined position inside the framework (step S5). More specifically, the unit moving step involves moving the interior unit U to a predetermined position inside the framework of the building (step S5-1), and removing the moving jig 1 from the interior unit U (step S5-2). As shown in Fig. 2, fixing holes F1 for fixing the floor F to the building frame are formed at a predetermined interval on the upper surface of the floor F (panel floor) inside the building frame. If this is done, there is a risk that the caster part 20 of the moving jig 1 will fall into the fixing hole F1. Therefore, assuming that the moving jig 1 will fall into the fixing hole F1, the moving jig 1 is provided with three caster parts 20.

[0042] Thereafter, a worker performs a "unit installation process" in which the interior unit U is installed at a predetermined position inside the framework (step S6). More specifically, the height and position of the interior unit U are adjusted, the leg members U3 of the interior unit U are fixed onto the floor F using adhesive, and the piping work for the interior unit U is performed. When the above step S6 is completed, the series of work steps is completed.

[0043] The above construction method makes it possible to realize a construction method that enables the interior unit U preassembled in a factory to be suitably installed inside the framework of a building. In particular, by using the moving jig 1, it becomes possible to temporarily place the interior unit U in a state where it is raised above the floor, and to move the interior unit U suitably.

[0044] <Another embodiment of the moving jig> Next, second and third embodiments of the moving jig will be described with reference to Figs. 10A and 10B and Figs. 11A and 11B. Incidentally, the description of the contents overlapping with those of the above-mentioned moving jig 1 will be omitted.

[0045] The moving jig 101 of the second embodiment is different from the moving jig 1 in the configurations of the switching portion 140 and the regulating member 150. In the moving jig 201 of the third embodiment, the configuration of the regulating member 250 is different.

[0046] The moving jig 101 of the second embodiment includes a switching unit 140A that switches the first side wall portion 132 of the holding portion 130 between a "first state" and a "second state", a switching unit 140B that switches the second side wall portion 133 between the "first state" and the "second state", and a regulating member 150 that regulates each of the first side wall portion 132 and the second side wall portion 133 in the "first state".

[0047] The switching portion 140A (140B) is a hinge member that connects the first side wall portion 132 (the second side wall portion 133) to the bottom wall portion 131 so as to be rotatable therewith. In the above configuration, as shown in FIG. 10B, when holding portion 130 is in the "second state", bottom wall portion 131, first side wall portion 132 and second side wall portion 133 form a substantially flat surface. Therefore, even if the lower end of the interior unit U is a substantially flat surface, the interior unit U can be favorably supported.

[0048] The regulating member 150 is mainly composed of a fixing nut 151 provided on the upper surface of the main body portion 110, and a regulating bolt 152 (wing bolt) that penetrates the main body portion 110 and screws into the fixing nut 151, extends upward from the main body portion 110, and connects to the first side wall portion 132 (protruding wall portion 132a). In the above configuration, as shown in FIG. 10A, when the regulating member 150 is in the "regulating position", the regulating bolt 152 is connected to the protruding wall portion 132a (133a) protruding from the first side wall portion 132 (second side wall portion 133). 10B, when the restricting member 150 is in the "unrestricted position", the restricting bolt 152 is disposed at a position lower than the holding portion 130. As shown in FIG.

[0049] Even with the above configuration, a moving jig that can stably hold the interior unit U and can be easily removed from the interior unit U can be realized.

[0050] The moving jig 201 of the third embodiment includes a restricting member 250 that restricts the first side wall portion 232 in the "first state." The restricting member 250 has a hinge mechanism, and is mainly composed of a fixed plate 251 attached to the outer surface of the second side wall portion 233, and a movable plate 252 attached to the fixed plate 251 so as to be rotatable about a rotation shaft 253. The movable plate 252 extends from the fixed plate 251 towards the first side wall portion 232, and supports the first side wall portion 232 by means of claw portions 252a. The claw portion 252a is a protruding portion that comes into contact with the outer surface of the first side wall portion 232 to restrict the movement of the first side wall portion 232.

[0051] In the above configuration, when the restricting member 250 is in the "restricting position", the claw portion 252a of the movable plate 252 abuts against the outer surface of the first side wall portion 232, as shown in FIG. 11A. 11B, when the restricting member 250 is in the “non-restrictive position”, the movable plate 252 rotates and is disposed at a position away from the first side wall portion 232. As shown in FIG.

[0052] Even with the above configuration, a moving jig that can stably hold the interior unit U and can be easily removed from the interior unit U can be realized.

[0053] <Other embodiments> In the above embodiment, as shown in Figures 2 and 3, the moving jig 1 is used to temporarily place the interior unit U and to move the interior unit U on the floor, but this can be changed without being particularly limited. For example, it may be used when temporarily placing and moving a heavy box-like object, or when temporarily placing and moving a suspended object other than a heavy object.

[0054] In the above embodiment, as shown in FIG. 4, the moving jig 1 is provided with three caster parts 20, but this is not particularly limited and can be modified. For example, the moving jig 1 may be configured with one caster portion 20 in order to achieve a more compact shape. Also, for example, the moving jig 1 may be provided with four or more caster parts 20 in order to allow it to be moved conveniently on a floor (panel floor) within a building.

[0055] In the above embodiment, as shown in FIG. 4, the moving jig 1 is provided with the height adjustment member 60, but is not particularly limited thereto, and the height adjustment member 60 may be omitted.

[0056] In the above embodiment, as shown in FIG. 7, the moving jig 1 is provided with a height adjustment means composed of fixing nuts 61, 62 and a height adjustment bolt 63, but the height adjustment means is not particularly limited and can be modified. For example, the "height adjustment member" may be composed of a "base member" that has a plurality of engaging recesses formed at intervals in the vertical direction on its outer surface and is long in the vertical direction, and a "slide member" that has engaging protrusions that can engage with the engaging recesses and moves (slides) in the vertical direction relative to the base member. In this way, by engaging the engaging protrusions with predetermined engaging recesses, the height position of the slide member can be changed, and the height position of the holding part attached to the slide member can be changed. Alternatively, a known height adjustment means using a mechanical structure may be used.

[0057] In the above embodiment, as shown in Figures 6A and 6B, the switching portion 40 has a hinge mechanism and is capable of switching the holding portion 30 (first side wall portion 32) between a first state and a second state, but this can be changed without being limited to the hinge mechanism. For example, it may be a slide mechanism that allows the first side wall portion 32 to slide up and down, or it may be an attachment / detachment mechanism (removal mechanism) that allows the first side wall portion 32 to be attached and detached. Alternatively, a known switching means having a mechanical structure may be used. The same applies to the restricting member 50, and a known movement restricting means having a mechanical structure may be used.

[0058] In the above embodiment, the moving jig and the construction method including the moving jig according to the present invention have been mainly described. However, the above embodiment is merely an example for facilitating understanding of the present invention, and is not intended to limit the present invention. The present invention can be modified or improved without departing from the spirit of the present invention, and the present invention naturally includes equivalents thereof.
