Description

[Technical field]

[0001] The present invention relates to a building installation method, a building unit and a building unit pair. [Background technology]

[0002] When mounting building equipment directly on a frame and installing it in a building unit, for example if the building equipment is a unit bath, a frame of a different shape is required depending on the specifications of the unit bath, etc. Patent Document 1 discloses a method of mounting building equipment that reduces restrictions on the shape of the frame by mounting the building equipment on the building unit with a flooring material between them. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2015-132058 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the mounting method described in Patent Document 1, it is necessary to collect the laying material after mounting the building equipment on the building unit, and the productivity is reduced by the time required to collect the laying material.

[0005] In consideration of the above, an object of the present invention is to provide a building equipment installation method, a building unit, and a building unit pair that can further improve productivity. [Means for solving the problem]

[0006] The method for installing building equipment according to the first aspect includes an assembly process for assembling building equipment outside a plurality of building units that constitute a building; a sliding layer providing process for providing a sliding layer on the bottom surface of the building equipment to make the building equipment more slippery; a loading process for placing the building equipment with the sliding layer provided thereon onto a cart; a guiding process for guiding the building equipment, while placed on the cart, to a position aligned with the floor surface of a predetermined building unit among the plurality of building units; a moving process for sliding and moving the building equipment to a predetermined position of the predetermined building unit with the cart positioned in the aligned position; and a fixing process for fixing the building equipment to the predetermined building unit at the predetermined position.

[0007] Conventionally, the assembly of building equipment is performed at the installation site of the building equipment within the building unit. Therefore, it is necessary to stop the main production line until the assembly of the building equipment is completed. In contrast, in the method for installing building equipment according to the first aspect, the building equipment is assembled outside the multiple building units constituting the building, and a sliding layer is provided on the bottom surface of the assembled building equipment, so that the building equipment is slid and moved to a predetermined position of the building unit and fixed. In this way, by assembling the building equipment outside the building unit and then fixing it to a predetermined position of the building unit, it is possible to off-load the assembly of the building equipment, and the man-hours of the main production line in the factory can be reduced. In addition, in the method for installing building equipment according to the first aspect, the assembled building equipment is fixed to the building unit while the sliding layer that makes the building equipment slippery is provided on the bottom surface of the assembled building equipment, so that the work of recovering the sliding layer does not occur.

[0008] In this way, the building equipment installation method of the first aspect allows work from assembling the building equipment to fixing it to the building unit to be carried out within the factory while shortening the labor hours on the main production line, and furthermore, since there is no need to remove the sliding layer, productivity can be improved compared to when the building equipment is assembling within the building unit.

[0009] A method for installing building equipment according to a second aspect includes an assembly process for assembling building equipment outside a plurality of building units constituting a building, a sliding layer providing process for providing a sliding layer on the bottom surface of the building equipment to make the building equipment more slippery, a placement process for placing the building equipment with the sliding layer provided thereon onto a dolly, a guiding process for guiding the building equipment, while placed on the dolly, to a position aligned with a floor surface of a predetermined first building unit among the plurality of building units, and, while the dolly is positioned in the aligned position, sliding and moving the building equipment into the interior of the first building unit. the first building unit and the second building unit arranged adjacent to each other; a joining process for joining the first building unit and a second building unit arranged adjacent to the first building unit; a second moving process for releasing the temporarily fixed building equipment and sliding and moving the building equipment to a predetermined position straddling the first building unit and the second building unit; and a final fixing process for final fixing the building equipment to the first building unit and the second building unit at the predetermined position.

[0010] In the method for installing building equipment according to the second aspect, the building equipment is assembled outside the building units constituting the building, and a sliding layer is provided on the bottom surface of the assembled building equipment, so that the building equipment is slid and moved to a predetermined position of the first building unit and temporarily fixed therein. In this way, by assembling the building equipment outside the first building unit and then temporarily fixing it to a predetermined position of the first building unit, it is possible to off-site the assembly of the building equipment, and it is possible to reduce the man-hours of the main production line in the factory. In addition, in the method for installing building equipment according to the second aspect, the assembled building equipment is fixed to the first building unit with a sliding layer provided on its bottom surface to make the building equipment slippery, so there is no need to remove the sliding layer.

[0011] Furthermore, in the building equipment installation method according to the second aspect, the building equipment can be slid and moved by releasing the temporary fixation. Therefore, even if the building equipment cannot be permanently fixed in the building units in the factory, for example when installing building equipment across the floor surfaces of two building units, the building equipment can be temporarily fixed to the first building unit in the factory, and after placing the second building unit adjacent to the first building unit on site, the temporary fixation of the building equipment can be released and the building equipment can be slid and moved to a predetermined position that straddles the first building unit and the second building unit.

[0012] In this way, the building facilities installation method according to the second aspect makes it possible to carry out work from assembling the building facilities to temporarily fixing them to the first building unit in a factory while shortening the man-hours on the main production line, and furthermore, since the building facilities can be fixed on-site by sliding it to a predetermined position that straddles the floor surfaces of the first building unit and the second building unit, productivity can be improved compared to when the building facilities are assembling on-site. Furthermore, the building facilities installation method according to the second aspect does not require the work of recovering the sliding layer, so productivity can be further improved.

[0013] A third aspect of the method for installing building equipment is the same as the first aspect, and in the moving step, the building equipment is changed direction within the specified building unit and moved to the specified position.

[0014] A fourth aspect of the method for installing building equipment has the configuration of the second aspect, in which in the first moving step, the building equipment is changed direction within the specified building unit.

[0015] In the building equipment installation methods according to the third and fourth aspects, a sliding layer is provided on the bottom surface of the building equipment, so that the building equipment can be slid within the building unit to change direction. By changing the direction of the building equipment within a given building unit and moving it to a given position in this way, for example, in a main production line, the building unit can be moved along the flow direction with the short side direction of the building unit positioned in the flow direction of the main production line, so that the working space of the main production line can be reduced.

[0016] A building unit according to a fifth aspect is one of a plurality of building units, assembled outside the plurality of building units, and has building equipment having a sliding layer on the bottom surface to make the floor surface slippery, fixed in a predetermined position.

[0017] In the building unit according to the fifth aspect, the building equipment assembled outside the multiple building units is fixed in a predetermined position, so there is no need to assemble the building equipment on-site. In addition, in the building unit according to the fifth aspect, the building equipment is fixed in a predetermined position with a sliding layer on the bottom surface that makes the floor surface slippery, so there is no need to remove the sliding layer. In this way, in the building unit according to the fifth aspect, the amount of on-site work can be reduced compared to when the building equipment is assembled on-site, so productivity can be further improved.

[0018] The building unit of the sixth aspect is one of a plurality of building units, which is assembled outside the plurality of building units, and has building equipment on the bottom surface which has a sliding layer to make the floor surface slippery, temporarily fixed in a predetermined position.

[0019] In the building unit according to the sixth aspect, the building equipment assembled outside the multiple building units is temporarily fixed in a predetermined position, so there is no need to assemble the building equipment on-site. Also, in the building unit according to the sixth aspect, the building equipment is temporarily fixed in a predetermined position with a sliding layer on the bottom surface that makes the floor surface slippery, so there is no need to remove the sliding layer. In this way, in the building unit according to the fifth aspect, the amount of on-site work can be reduced compared to when the building equipment is assembled on-site, so productivity can be further improved.

[0020] A building unit pair in the seventh aspect is two adjacent building units among a plurality of building units that are joined together, and is assembled outside the plurality of building units. Building equipment having a sliding layer on the bottom surface to make the floor surface more slippery is fixed across the floor surfaces of the two building units.

[0021] In the building unit pair according to the seventh aspect, the building equipment is assembled outside the multiple building units, so there is no need to assemble the building equipment on-site. In addition, in the building unit pair according to the seventh aspect, a sliding layer is provided on the bottom surface of the building equipment to make the floor surface slippery, so that the building equipment can be moved from one building unit to a position that spans the floor surface of the other building unit on-site and fixed there. In this way, in the building unit pair according to the seventh aspect, the amount of on-site work can be reduced compared to when the building equipment is assembled on-site, so productivity can be further improved. Effect of the Invention

[0022] As described above, the building equipment installation method, building unit, and building unit pair according to the present invention have the excellent effect of further improving productivity. [Brief description of the drawings]

[0024] First Embodiment Hereinafter, a kitchen-equipped building unit 100 as a building unit according to the first embodiment will be described with reference to Figs. 1 to 4. In this embodiment, the building unit 10 constitutes a building (not shown) such as a two-story modular building, for example, and the building is constituted by connecting a plurality of building units 10. Each building unit 10 may have a configuration (not shown) in which four pillars are erected between a ceiling frame and a floor frame that are assembled in a rectangular frame shape, but is not limited to this and may have another box-shaped frame structure.

[0025] The kitchen-equipped building unit 100 of this embodiment is one of the building units 10 constituting a building, and has a kitchen 20 disposed therein as building equipment. In this embodiment, the building equipment is the kitchen 20 as an example, but the building equipment of the present invention is not limited to the kitchen 20 and may be, for example, a washstand. In this embodiment, the kitchen-equipped building unit 100 refers to a building unit after the kitchen 20 is installed, and the building unit 10 refers to a building unit without the kitchen 20 installed.

[0026] Next, a method of installing the kitchen 20 in the building unit 10 will be described. Fig. 1 is a schematic diagram showing an assembly step and a sliding layer provision step in the method of installing building equipment according to the first embodiment of the present invention, Fig. 2 is a schematic diagram showing a placement step, and Fig. 3 is a schematic diagram showing a guiding step. Fig. 4 is a schematic diagram showing a kitchen-equipped building unit 100 according to the first embodiment of the present invention. In each drawing, the height direction of the building unit 10 will be described as the up-down direction.

[0027] The method of installing the kitchen 20 in the building unit 10 involves the steps of (1) assembly, (2) providing a sliding layer, (3) placement, (4) guiding, (5) moving, and (6) fixing, in that order.

[0028] (1) In the assembly process, the kitchen 20 is assembled outside the building units 10 that constitute the building. Specifically, the assembly process is carried out in a factory that produces the kitchen-equipped building units 100, separate from the main production line for the kitchen-equipped building units 100. As shown in the left diagram of FIG. 1, first, the countertop 22 and the storage unit 24 are assembled as examples of components that constitute the kitchen 20. The countertop 22 includes a worktop 22A made of a plate-like member, and a sink 22B and a stove 22C attached to the worktop 22A. The storage unit 24 includes, as examples, a first cabinet 24A, a dishwasher 24B, and a second cabinet 24C. Note that the components of the countertop 22 and the storage unit 24 are not limited to these, and other components may be included.

[0029] 1, first cabinet 24A, dishwasher 24B, and second cabinet 24C are fixed to each other in the horizontal direction to assemble storage unit 24. Kitchen 20 is assembled by fixing top panel 22 to the upper surface of assembled storage unit 24.

[0030] (2) In the sliding layer disposing step, as shown in the center diagram of FIG. 1, a sliding layer 26 that makes the kitchen 20 slippery is provided on the bottom surface 20A of the assembled kitchen 20. The sliding layer 26 is, for example, a layer made of a resin material with a small friction coefficient, such as fluororesin, and is made of tape or the like. The sliding layer 26 is not limited to tape, and may be a coating material or the like. In this embodiment, as an example, the sliding layer 26 made of tape is attached to the bottom surface 20A of the kitchen 20. The tape as the sliding layer 26 may be one sheet or multiple sheets. The sliding layer 26 may be provided over the entire surface of the bottom surface 20A, or may be provided in a scattered manner. In this way, the kitchen 20 provided with the sliding layer 26 is assembled, as shown in the right diagram of FIG. 1.

[0031] (3) In the loading step, as shown in FIG. 2, the kitchen 20 is loaded onto the cart 40. Any type of cart 40 may be used as long as it can be moved with the kitchen 20 loaded thereon. In this embodiment, as an example, the cart 40 is provided with a lifting function (not shown) that allows it to be raised and lowered in the vertical direction. Note that in this embodiment, the task of loading the kitchen 20 onto the cart 40 is performed manually by a worker, but the present invention is not limited to this, and equipment such as a forklift may also be used.

[0032] (4) In the guiding process, as shown in Fig. 3, the kitchen 20 provided with the sliding layer 26 is placed on a cart 40 and guided to a position aligned with the floor surface 12 of the building unit 10 in which the kitchen 20 will be installed. Specifically, the cart 40 carrying the kitchen 20 is brought adjacent to the building unit 10, which is placed on a cart 50, for example. At this time, the building unit 10 is placed, for example, so that its longitudinal direction is perpendicular to the flow of the main production line of the factory, i.e., so that its lateral direction is aligned with the flow of the main production line of the factory.

[0033] In this embodiment, the lifting function of the cart 40 is used to guide the bottom surface of the kitchen 20 to a position aligned with the floor surface 12 of the building unit 10. If there is a gap or step between the kitchen 20 and the floor surface 12 of the building unit 10, a board or the like is used as a bridge.

[0034] (5) In the moving step, as shown in Fig. 3, with the cart 40 placed in the above-mentioned aligned position, the kitchen 20 provided with the sliding layer 26 is slid and moved to a predetermined position on the building unit 10. Specifically, the worker H moves the kitchen 20 by pushing it toward the floor surface 12 side of the building unit 10 (i.e., in the direction of the arrow F).

[0035] In this embodiment, the kitchen 20 is slid and turned within the building unit 10, so that the kitchen 20 is actually moved to a predetermined position where it is fixed.

[0036] (6) In the fixing step, as shown in Fig. 4, the kitchen 20 is fixed in a predetermined position within the building unit 10 where the kitchen 20 is to be fixed. Specifically, the kitchen 20 is fixed by a known method used for fixing the kitchen 20, for example, by using screws on a wall or floor. In this way, the building unit 10 with the kitchen 20 fixed therein is completed as the building unit with kitchen 100.

[0037] The kitchen-equipped building unit 100 with the kitchen 20 installed in this manner is transported by known transportation means to the site where the building is to be constructed.

[0038] Next, the operation and effects of the first embodiment will be described.

[0039] Fig. 7 is a schematic diagram for explaining a conventional method for installing a kitchen 20. In Fig. 7, the same parts as those in the first embodiment described above are indicated by the same reference numerals, and detailed explanations will be omitted here. Conventionally, when installing a kitchen 20 in a building unit 10, assembly is performed at an installation location within the building unit 10 where the kitchen 20 is actually disposed.

[0040] Therefore, when installing the kitchen 20 in a factory, it is necessary to stop the main production line until the assembly of the kitchen 20 is completed. In contrast, in the installation method of the kitchen 20 according to the first embodiment, the kitchen 20 is assembled outside the building unit 10. Then, by providing a sliding layer 26 on the bottom surface 20A of the assembled kitchen 20, the kitchen 20 provided with the sliding layer 26 is slid and moved to a predetermined position of the building unit 10 and fixed therein. In this way, by assembling the kitchen 20 outside the building unit 10 and then fixing it to a predetermined position of the building unit 10, it is possible to off-load the assembly of the kitchen 20, and it is possible to reduce the man-hours of the main production line in the factory. In addition, in the installation method of the kitchen 20 according to the first embodiment, the kitchen 20 is fixed to the building unit 10 while the sliding layer 26 that makes the kitchen 20 slippery is provided on the bottom surface 20A of the assembled kitchen 20, so that the operation of recovering the sliding layer 26 is not required.

[0041] In this way, the installation method of the kitchen 20 in accordance with the first embodiment makes it possible to carry out work from assembling the kitchen 20 to fixing it to the building unit 10 within a factory while reducing the labor hours on the main production line, and furthermore, since there is no need to remove the sliding layer 26, productivity can be improved compared to when the kitchen 20 is assembled within the building unit 10.

[0042] Furthermore, in the installation method for kitchen 20 according to the first embodiment, since a sliding layer 26 is provided on the bottom surface 20A of kitchen 20, kitchen 20 provided with sliding layer 26 can be slid to change direction within building unit 10. By changing the direction of kitchen 20 within a given building unit 10 and moving it to a given position in this way, for example, in a main production line, the building unit 10 can be moved along the flow direction with the short side direction of the building unit 10 positioned in the flow direction of the main production line, thereby reducing the working space of the main production line.

[0043] In addition, in the building unit 100 with the kitchen 20 installed as described above, the kitchen 20 assembled outside the building unit 10 is fixed at a predetermined position, so there is no need to assemble the kitchen 20 on-site. In addition, in the building unit 100 with the kitchen according to the first embodiment, the kitchen 20 is fixed at a predetermined position with the sliding layer 26 provided on the bottom surface 20A to make the floor surface slippery, so there is no need to collect the sliding layer 26. In this way, in the building unit 100 with the kitchen according to the first embodiment, the amount of on-site work can be reduced compared to the case where the kitchen 20 is assembled on-site, so productivity can be further improved.

[0044] <Second embodiment> Hereinafter, a building unit 110 with a kitchen as a building unit according to the second embodiment will be described with reference to Figures 5 and 6. Figure 5 is a schematic diagram showing a building unit 110 with a kitchen according to the second embodiment of the present invention, and Figure 6 is a schematic diagram showing a building unit pair 200 according to the second embodiment of the present invention. In this embodiment, the same components as those in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted here.

[0045] In this embodiment, first, a method of installing a kitchen 20 in a first building unit 10A of a first building unit 10A and a second building unit 10B, which are two adjacent building units 10 joined together among a plurality of building units that make up a building, will be described.

[0046] The method of installing the kitchen 20 in the first building unit 10A involves sequentially performing the steps of (11) assembly step, (12) sliding layer provision step, (13) placement step, (14) guiding step, (15) first movement step, and (16) temporary fixing step. Note that the steps of (11) assembly step, (12) sliding layer provision step, (13) placement step, and (14) guiding step are the same as the steps of (1) assembly step, (2) sliding layer provision step, (3) placement step, and (4) guiding step in the first embodiment, and the step of (15) first movement step is the same as the step of (5) movement in the first embodiment, so detailed explanations will be omitted here.

[0047] (16) In the temporary fixing step, while the "fixing" in the first embodiment described above is a permanent fixation in which the kitchen 20 is actually fixed to the building unit 10, the "temporary fixing" in this embodiment is a step in which the kitchen 20 is removably fixed to the first building unit 10A. Specifically, as shown in FIG. 5, the lower end of the side of the kitchen 20 is fixed to the wall or floor of the first building unit 10A using a batten 60 or the like. Also, for example, the kitchen 20 is fixed to the wall or floor of the first building unit 10A using masking tape, cardboard 60, string, or the like. In this way, the kitchen-equipped building unit 110 is completed as the first building unit 10A in which the kitchen 20 is temporarily fixed inside. In the second embodiment, the predetermined position at which the kitchen 20 is fixed is a position in the first building unit 10A where the kitchen 20 is easily fixed, such as approximately the center, for example.

[0048] Next, a method for installing the kitchen 20 in the joined first building unit 10A and second building unit 10B will be described. The method for installing the kitchen 20 in the joined first building unit 10A and second building unit 10B involves sequentially carrying out (17) a joining step, (18) a second moving step, and (19) a main fixing step.

[0049] (17) In the joining step, the first building unit 10A and the second building unit 10B arranged adjacent to the first building unit 10A are joined. Specifically, as an example, the opposing side portions of the first building unit 10A and the second building unit 10B arranged adjacent to each other in the horizontal direction are joined by fastening the pair of connecting members together using a pair of connecting members. Note that the joining method is not limited to this, and known techniques can be used.

[0050] (18) In the second moving step, the temporarily fixed kitchen 20 is released, and the kitchen 20 is slid and moved to a predetermined position spanning the first building unit 10A and the second building unit 10B, as shown in Fig. 6. Specifically, the worker presses the kitchen 20 from the first building unit 10A toward the second building unit 10B, i.e., in the direction shown by the arrow P in the figure, thereby moving the kitchen 20 to the above-mentioned predetermined position.

[0051] (19) In this fixing step, similar to the (6) fixing step in the first embodiment, the kitchen 20 is fixed at a predetermined position straddling the first building unit 10A and the second building unit 10B. Specifically, the kitchen 20 is fixed by a known method used for fixing the kitchen 20, and as an example, it is fixed by using screws to a wall or floor. In this way, the building unit pair 200 in which the kitchen 20 is fixed straddling the first building unit 10A and the second building unit 10B is completed.

[0052] Next, the operation and effects of the second embodiment will be described.

[0053] In the method of installing the kitchen 20 according to the second embodiment, the kitchen 20 is assembled outside the first building unit 10A, and a sliding layer 26 is provided on the bottom surface 20A of the assembled kitchen 20, allowing the kitchen 20 to slide and move to a predetermined position on the first building unit 10A and then temporarily fixed therein. In this way, by assembling the kitchen 20 outside the first building unit 10A and then temporarily fixing it to a predetermined position on the first building unit 10A, it is possible to off-site the assembly of the kitchen 20, and thus reduce the man-hours required for the main production line in the factory.

[0054] Furthermore, in the installation method for the kitchen 20 of the second embodiment, the assembled kitchen 20 is fixed to the first building unit 10A with the sliding layer 26, which makes the kitchen 20 slippery, still attached to the bottom surface 20A, so that there is no need to remove the sliding layer 26.

[0055] Furthermore, in the installation method of the kitchen 20 according to the second embodiment, the kitchen 20 can be slid and moved by releasing the temporary fixation. Therefore, even if the kitchen 20 cannot be permanently fixed in the first building unit 10A in a factory, such as when installing the kitchen 20 across the floor surfaces 12 of two building units 10, the kitchen 20 can be temporarily fixed to the first building unit 10A in a factory, and after the second building unit 10B is placed adjacent to the first building unit 10A on-site, the temporary fixation of the kitchen 20 can be released and the kitchen 20 can be slid and moved to a predetermined position across the first building unit 10A and the second building unit 10B.

[0056] In this way, the installation method for kitchen 20 according to the second aspect allows work from assembling kitchen 20 to temporarily fixing it to first building unit 10A to be carried out in a factory while shortening the man-hours on the main production line, and further allows kitchen 20 to be slid and moved to a predetermined position across floor surface 12 between first building unit 10A and second building unit 10B on site and then fixed, thereby improving productivity compared to assembling kitchen 20 on site. Furthermore, the installation method for kitchen 20 according to the second embodiment does not require the work of recovering sliding layer 26, thereby further improving productivity.

[0057] In addition, the kitchen-equipped building unit 110, which is the first building unit 10A in which the kitchen 20 is installed as described above, does not need to be assembled on-site because the kitchen 20 assembled outside the first building unit 10A is temporarily fixed in a predetermined position. In addition, in the kitchen-equipped building unit 110 according to the second embodiment, the kitchen 20 is temporarily fixed in a predetermined position with the bottom surface 20A provided with a sliding layer 26 that makes the floor surface slippery, so no work is required to recover the sliding layer 26. In this way, in the kitchen-equipped building unit 110 according to the second embodiment, the amount of on-site work can be reduced compared to the case in which the kitchen 20 is assembled on-site, and productivity can be further improved.

[0058] In addition, in the building unit pair 200 according to the second embodiment, the kitchen 20 is assembled outside the first building unit 10A and the second building unit 10B, so there is no need to assemble the kitchen 20 on-site. In addition, in the building unit pair 200 according to the second embodiment, the bottom surface 20A of the kitchen 20 is provided with a sliding layer 26 that makes the floor surface 12 slippery, so that the kitchen 20 can be moved to a position that straddles the floor surfaces 12 of the first building unit 10A and the second building unit 10B on-site and fixed therein. In this way, in the building unit pair 200 according to the second embodiment, the amount of on-site work can be reduced compared to the case where the kitchen 20 is assembled on-site, so that productivity can be further improved.

[0059] (Supplementary information regarding this embodiment) In the above embodiment, in the (4) guiding step, the building unit 10 is arranged so that its longitudinal direction is perpendicular to the flow of the main production line of the factory, i.e., its lateral direction is aligned with the flow of the main production line of the upright, and the kitchen 20 is changed in direction in the (5) moving step or the (15) first moving step, but the present invention is not limited to this. In the (4) guiding step, the building unit 10 may be arranged in advance so that its lateral direction is perpendicular to the flow of the main production line of the factory, i.e., its longitudinal direction is aligned with the flow of the main production line of the upright. In this case, the kitchen 20 does not need to be changed in direction in the (5) moving step or the (15) first moving step.

[0060] An example of an embodiment of the present invention has been described above, but the embodiment of the present invention is not limited to the above, and one embodiment and various modified examples may be used in appropriate combination, and it is of course possible to implement the present invention in various forms without departing from the gist of the present invention.
