Embodiments for Carrying Out the Invention

[0020] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, although various technically preferable limitations are imposed on the embodiments described below for carrying out the present invention, the technical scope of the present invention is not limited to the following embodiments and illustrated examples. Note that the directions in the following embodiments and illustrated examples are merely set for convenience of explanation.

[0021] In FIG. 1 and the like, reference numerals 1 and 100 denote mobile units. The mobile units 1 and 100 of the present embodiment are trailer houses, which are placed on a carriage 2 and towed and transported by an automobile (not shown), and can be placed at a stationary place while being placed on the carriage 2.

[0022] In addition, the mobile units 1 and 100 have obtained vehicle inspections and are set to sizes within the legal regulations (Building Standards Law, Road Transport Vehicle Law) (restriction values in Article 2 of the safety standards: within 2.5 m in vehicle width, within 12 m in vehicle length, and within 3.8 m in vehicle height). Thereby, the mobile units 1 and 100 can legally move on public roads. However, in some cases, they may be set to sizes larger than the restriction values by obtaining special permission. Furthermore, the mobile units 1 and 100 shall satisfy all the criteria required for being placed at a stationary place.

[0023] The carriage 2, also called a chassis, includes a support base 3 to which wheels 3a are attached, and a plurality of support legs (not shown) detachably provided on the support base 3. The support base 3 has a box-shaped unit body of the mobile units 1, 100 placed thereon and integrated. Also, at the front end of this support base 3, a connecting portion (not shown) that protrudes forward and is connected to an automobile is integrally formed. The plurality of support legs are provided at a total of six locations, namely, at the four corners of the support base 3 and at two locations near the wheels 3a (the center in the length direction of the support base 3). The support legs are jack devices capable of manually raising and lowering the portion in contact with the support base 3.

[0024] The mobile units 1, 100 are arranged adjacent to each other in a place where they can be stationary. A slight gap is strictly formed between these mobile units 1, 100. The width of the gap is set to about 100 to 300 mm, for example. Also, the length of the gap between the mobile units 1, 100 is equal to the length of the mobile units 1, 100 in the front-rear direction. Furthermore, the height of the gap between the mobile units 1, 100 is equal to the length of the mobile units 1, 100 in the height direction. Also, such mobile units 1, 100 are arranged in a state where the communication ports 14a, 114a formed on the opposing side surfaces face each other (in a parallel positional relationship and facing directly forward).

[0025] Also, at least one of the mobile units 1, 100 has an entrance / exit 13a different from the communication ports 14a, 114a. In the present embodiment, as shown in FIG. 1, the entrance / exit 13a is formed in the rear second side wall 13 of one of the mobile units 1. A door is provided at the entrance / exit 13a, and this entrance / exit 13a can be used as a front door.

[0026] 〔Regarding the configuration of the mobile unit〕 Next, the configuration of the mobile units 1, 100 will be described in detail. Note that the mobile units 1 and 100 of the present embodiment, which are trailer houses, are configured to include a carriage 2. Hereinafter, a box-shaped unit body placed on the support base 3 of the carriage 2 will be described. In the present embodiment, the mobile unit 1 located on the right side in FIG. 1 is referred to as the first mobile unit 1, and the mobile unit 100 located on the left side is referred to as the second mobile unit 100.

[0027] As shown in FIGS. 1 to 3 and FIGS. 5 to 7, the unit bodies of the first mobile unit 1 and the second mobile unit 100 include, as an outer shell, a floor (not shown) placed on the support base 3 and integrated, roofs 11 and 111, and four side walls 12 to 15 and 113 to 115 provided between the floor and the roofs 11 and 111, and are formed in a box shape. Such a unit body is long in one direction (front-rear direction) and short in the other direction (left-right direction), and is formed in a rectangular parallelepiped shape.

[0028] The floor is long in one direction (front-rear direction) and short in the other direction (left-right direction), and is rectangular in plan view, and constitutes the entire surface of the floor in the space within the first mobile unit 1. Note that the floor is configured such that the floor body is made of a wooden building panel with a hollow interior. A floor finishing material (for example, a flooring material) is provided on the upper surface of the floor body, and a heat insulating material is filled in the hollow interior.

[0029] The roof 11 of the first mobile unit 1 is a single-slope roof in which the side adjacent to the second mobile unit 100 (left side) is high and the opposite side (right side) is low. In addition, the roof 111 of the second mobile unit 100 is also a single - slope roof where the side adjacent to the first mobile unit 1 (right side) is higher and the opposite side (left side) is lower. Therefore, when the first mobile unit 1 and the second mobile unit 100 are arranged adjacent to each other, the roofs 11 and 111 of these mobile units 1 and 100 will appear as if they are gable roofs. Also, as will be described later, since communication ports 14a and 114a are provided on the opposing side walls 14 and 114 of the unit bodies of both mobile units 1 and 100, it is also possible to prevent rainwater from flowing toward the communication ports 14a and 114a. Note that the roofs 11 and 111 are such that the roof body is composed of a hollow - interior building wooden panel. A roofing material (for example, a galvanized steel sheet roof (registered trademark)) is provided on the surface of the roof body, and a heat - insulating material is filled in the internal hollow part. Also, a ceiling material (for example, a decorative - pasted ceiling board material) is attached to the lower surface of the roof body. Since the roofs 11 and 111 are single - slope roofs, when viewed from the inside of the unit body, the ceiling is a sloped ceiling. However, it is not limited to this, and a horizontal ceiling composed of a soffit or a ceiling material or the like may be formed below the roof body.

[0030] The first mobile unit 1 has, as four - sided side walls, a first side wall 12, a second side wall 13, a third side wall 14, and a fourth side wall 15. The first side wall 12 is provided at one end side (front - end side) in the length direction of the floor. The second side wall 13 is provided at the other end side (rear - end side) in the length direction of the floor. The third side wall 14 is provided between the other end in the width direction (left - hand end) of the first side wall and the other end in the width direction (left - hand end) of the second side wall 13. The fourth side wall 15 is provided between the one end in the width direction (right - hand end) of the first side wall and the one end in the width direction (right - hand end) of the second side wall 13. The first side wall 12 and the second side wall 13 form the front and rear surfaces of the unit body and have a short width dimension (dimension in the left - right direction). The third side wall 14 and the fourth side wall 15 form the left and right surfaces of the unit body and have a long width dimension (dimension in the front - rear direction). In addition, among the four side walls 12 to 15 of the first mobile unit 1, a first communication opening 14a, which is an opening for people to pass through, is formed in the third side wall 14 located on the side of the second mobile unit 100.

[0031] Among the four side walls 12 to 15 of the first mobile unit 1, a first communication opening 14a, which is an opening for people to pass through, is formed in the third side wall 14 located on the side of the second mobile unit 100. Also, a first door 14b for opening and closing the first communication opening 14a is provided on this third side wall 14. The first door 14b is a single - leaf door and is an inward - opening door that opens towards the internal space side of the first mobile unit 1.

[0032] Also, as described above, an entrance / exit 13a, which is an opening for people to pass through, is formed in the second side wall 13 of this first mobile unit 1. This entrance / exit 13a is not directed towards the second mobile unit 100 side but towards the outdoor space. Therefore, this entrance / exit 13a functions as the front - door entrance of the first mobile unit 1. Further, a front - door 13b, which is a door for opening and closing the entrance / exit 13a, is provided on the second side wall 13. Thereby, through the entrance / exit 13a, entry and exit between the internal space of the first mobile unit 1 and the outdoor space can be carried out. Note that since the unit body of the first mobile unit 1 is arranged at a certain height position by the trolley 2, the height position of the entrance / exit 13a also becomes high. Therefore, on the outdoor side of the entrance / exit 13a, lifting facilities such as stairs or slopes are to be installed in a state where they are not fixed to the first mobile unit 1.

[0033] The second mobile unit 100 has, as four side walls, a first side wall (not shown), a second side wall 113, a third side wall 114, and a fourth side wall 115. The first side wall is provided at one end side (front end side) in the length direction of the floor. The second side wall 113 is provided at the other end side (rear end side) in the length direction of the floor. The third side wall 114 is provided between one end in the width direction (right end) of the first side wall and one end in the width direction (right end) of the second side wall 113. The fourth side wall 115 is provided between the other end in the width direction (left end) of the first side wall and the other end in the width direction (left end) of the second side wall 113. As described above, the positional relationship of the four side walls 113 to 115 in the second mobile unit 100 is symmetric with respect to the left and right with the positional relationship of the four side walls 12 to 15 in the first mobile unit 1. That is, both the first mobile unit 1 and the second mobile unit 100 are configured such that the adjacent third side walls 14, 114 are in a tall state. The fourth side walls 15, 115 located on the side opposite to the third side walls 14, 114 are configured to be in a low state.

[0034] Further, the four side walls 113 to 115 are such that the wall body is composed of a wooden building panel with a hollow interior. An outer wall material (for example, a galvanized steel plate outer wall or a siding material) is provided on the outdoor side of the wall body, an inner wall material (for example, a gypsum board) is provided on the indoor side, and a wall finishing material (for example, a cloth) is applied, and the inner hollow portion is filled with a heat insulating material.

[0035] Among the four side walls 113 to 115 in the second mobile unit 100, a second communication port 114a, which is an opening for people to pass through, is formed in the third side wall 114 located in the first mobile unit 1. Further, a second door 114b for opening and closing the second communication port 114a is provided on this third side wall 114. The second door 114b is a single-opening door and is an inward-opening door that opens to the inner space side of the second mobile unit 100.

[0036] The first mobile unit 1 and the second mobile unit 100 configured as described above are adjacent to each other at a locatable position, and the communication ports 14a and 114a formed on the third side walls 14 and 114 facing each other are arranged in a state where they face each other (in a parallel positional relationship and facing directly). Further, in the present embodiment, in a state where the first communication port 14a and the second communication port 114a face each other, the first side wall 12 of the first mobile unit 1 and the first side wall of the second mobile unit 100 are arranged on the same vertical plane. Further, the second side wall 13 of the first mobile unit 1 and the second side wall 113 of the second mobile unit 100 are arranged on the same vertical plane. That is, in a state where the first communication port 14a and the second communication port 114a face each other, the first mobile unit 1 and the second mobile unit 100 are in a state where their front and rear positions are aligned.

[0037] 〔Regarding the connection and enclosure means〕 Next, the connection and enclosure means for connecting adjacent mobile units 1 and 100 to each other and forming the passage space 20 will be described.

The plurality of caulking portions 32b are provided so as to border a through hole that penetrates the second sheet piece 32 and the watertight materials 32a on the front and back.

[0045] The first holding portion 21 holds the first sheet piece 31 and includes an angle member 21a, a flat plate member 21b, and a fixing member 21c.

[0046] The angle member 21a is an angle metal with an L-shaped cross section. One side forming the L shape is a fixing piece fixed to the third side wall 14, and the other side forming the L shape is a holding piece for holding the first sheet piece 31. And one side of the angle member 21a is arranged on the outside, and the other side is arranged on the inside (on the side of the passage space 20). Note that, as shown in FIG. 2 and the like, at the position on the third side wall 14 where one piece of the angle member 21a is fixed, a fixing outer wall material 17 serving as a base for fixing the angle member 21a is provided.

[0047] The angle member 21a is divided into a plurality of parts so that the fixing work can be divided into a plurality of steps. That is, as shown in FIG. 2, the passage space 20 of the present embodiment has an upper edge portion 20a formed in a mountain shape, and one side edge portion 20b and the other side edge portion 20c are formed in a straight line. And the parts of the angle member 21a that define the shape of such a passage space 20 include a mountain-shaped part at the apex, a bent part that constitutes a bent part between the upper edge portion 20a and one side edge portion 20b and the other side edge portion 20c, a straight part that connects the mountain-shaped part and the bent parts on both sides, and a plurality of straight parts that constitute one side edge portion 20b and the other side edge portion 20c.

[0048] The flat plate member 21b is for sandwiching the first sheet piece 31 between the other one-sided portion that constitutes the L shape in the angle member 21a, and is divided into a plurality of parts so that the fixing work can be divided into a plurality. And between the other piece of the angle member 21a and the flat plate member 21b, the portion where the watertight material 31a and the caulking portion 31b in the first sheet piece 31 are provided is sandwiched.

[0049] A plurality of through holes are formed in the angle member 21a and the flat plate member 21b at the same intervals as the plurality of through holes bordered by the plurality of caulking portions 31b in the first sheet piece 31. And between the angle member 21a and the flat plate member 21b, the edge portion where the watertight material 31a in the first sheet piece 31 is provided is sandwiched, and in a state where the positions of the plurality of through holes in the angle member 21a, the flat plate member 21b, and the first sheet piece 31 are aligned, the fixing member 21c (bolt) is inserted into the plurality of through holes.

[0050] The fixing member 21c includes a bolt inserted into the through holes in the angle member 21a, the flat plate member 21b, and the first sheet piece 31, a nut provided by screwing the tip of the shaft portion of the bolt, and washers provided between the bolt and the flat plate member 21b and between the nut and the angle member 21a. The bolt is inserted into the through-hole with a washer interposed from the side of the flat plate member 21b located inside (on the side of the passage space 20) with respect to the angle member 21a. And the tip of the bolt protrudes outside the other piece of the angle member 21a, and a nut is provided with a washer interposed therebetween.

[0051] The second holding portion 22 holds the second sheet piece 32. Similar to the first holding portion 21, it includes an angle member 22a, a flat plate member 22b, and a fixing member 22c. These angle member 22a, flat plate member 22b, and fixing member 22c are provided symmetrically with respect to the angle member 21a, flat plate member 21b, and fixing member 21c in the first holding portion 21. Since the function and usage method for holding the second sheet piece 32 are the same as when the first holding portion 21 holds the first sheet piece 31, detailed description is omitted.

[0052] The waterproof sheet portion 30 is provided across between adjacent mobile units 1 and 100 such that the edge on the side of the first mobile unit 1 is held by the first holding portion 21 and the edge on the side of the second mobile unit 100 is held by the second holding portion 22. Further, the range in which the waterproof sheet portion 30 covers the passage space 20 is the upper edge portion 20a, one side edge portion 20b, and the other side edge portion 20c of the passage space 20. The lower edge portion 20d of the passage space 20 is covered by the floor portion 40.

[0053] The floor portion 40 is bridged between the adjacent mobile units 1 and 100 without being fixed to the adjacent mobile units 1 and 100 and is disposed at the lower edge portion 20d of the passage space 20. Such a floor portion 40 includes a support portion 41 bridged between the adjacent mobile units 1 and 100 and a floor surface portion 42 detachably fixed to the upper surface of the support portion 41, as shown in FIGS. 5 to 8.

[0054] In this embodiment, two support portions 41 are used, and the two support portions 41 are arranged at intervals in the front-rear direction in the gap between the mobile units 1 and 100. Such a support portion 41 has a support portion main body 41a formed in a square tube shape, and laying plates 41b provided on the lower surfaces of the front end portion and the rear end portion of the support portion main body 41a. The square tube-shaped support portion main body 41a has its front end portion and rear end portion open so that a person can put their hand inside and perform work. The front and rear laying plates 41b respectively protrude laterally beyond the left and right side surfaces of the support portion main body 41a. And the portions protruding laterally in this way are placed and spanned on the upper surfaces of the left edge portion of the support base 3 of the first mobile unit 1 and the upper surfaces of the right edge portion of the support base 3 of the second mobile unit 100.

[0055] The floor surface portion 42 is constituted by a wood-like molded product formed by extrusion molding a material in which wood powder obtained by pulverizing a cellulose material and a resin are kneaded and melted, and is provided so as to span between the two support portions 41. The floor surface portion 42 of the present embodiment is set to have a width dimension substantially equal to the width dimension of the support portion main body 41a, making it difficult for the waterproof sheet portion 30 to get caught. Such a floor surface portion 42 is formed in a state of including a plurality of hollow portions 42a formed to be long in the length direction and a notch portion 42b opened on the lower surface side.

[0056] The notch portion 42b is formed along the center line on the lower surface of the floor surface portion 42. Among the plurality of hollow portions 42a, rail members 43 made of metal and having a U-shaped cross section are inserted into the hollow portions 42a located on the left and right sides of the notch portion 42b. The rail member 43 has a plurality of through holes formed at positions spaced apart in the length direction of the rail member 43, and nuts are welded to the positions where these plurality of through holes are formed. Further, through holes are formed at positions corresponding to the plurality of through holes at the bottom of the floor surface portion 42 into which such a rail member 43 is inserted into the plurality of hollow portions 42a. Moreover, through holes are also formed at positions corresponding to the plurality of through holes in the upper surface portion of the support portion main body 41a on which the floor surface portion 42 is placed. Therefore, through holes are formed from the upper surface portion of the support portion main body 41a to the nuts in the hollow portion 42a. And fixing members such as the wing bolt 44 can be inserted into these through holes, and by screwing the tip of the wing bolt 44 into the nut of the rail member 43, the support portion 41 and the floor surface portion 42 can be joined.

[0057] The waterproof sheet portion 30 is provided from a position on the one-side edge portion 20b side to a position on the other-side edge portion 20c side of the passage space 20 among the floor portions 40 configured as described above. More specifically, one end portion of the waterproof sheet portion 30 located on the one-side edge portion 20b side of the passage space 20 among both end portions in the length direction of the waterproof sheet portion 30 is sandwiched between one end portion (front end portion) of the support portion 41 and one end portion (front end portion) of the floor surface portion 42. Further, the other end portion of the waterproof sheet portion 30 located on the other-side edge portion 20c side of the passage space 20 among both end portions in the length direction of the waterproof sheet portion 30 is sandwiched between the other end portion (rear end portion) of the support portion 41 and the other end portion (rear end portion) of the floor surface portion 42. Since the support portion 41 and the floor surface portion 42 can be joined by the wing bolt 44 as described above, both end portions in the length direction of the waterproof sheet portion 30 can be firmly sandwiched between the support portion 41 and the floor surface portion 42.

[0058] The waterproof sheet portion 30 has a position where the tooth head portion and the slider portion provided in the first element portion and the second element portion are thick and hard portions among the waterproof sheet portion 30. Therefore, when sandwiching both end portions in the length direction of the waterproof sheet portion 30 between the support portion 41 and the floor surface portion 42, as shown in FIG. 8, the thick and hard portion is arranged in the notch portion 42b of the floor surface portion 42. Thereby, the first sheet piece 31 and the second sheet piece 32 can be firmly sandwiched between the support portion 41 and the floor surface portion 42. In addition, the wing bolt 44 inserted into each through hole of the support portion main body 41a, the floor surface portion 42, and the rail member 43 may penetrate the first sheet piece 31 and the second sheet piece 32, or the coupling operation by the wing bolt 44 may be performed at a position where the terminals of the first sheet piece 31 and the second sheet piece 32 do not reach.

[0059] The waterproof sheet portion 30 has a first sheet piece 31 held by the first holding portion 21 and provided on the first mobile unit 1 side, and a second sheet piece 32 held by the second holding portion 22 and provided on the second mobile unit 100 side. Moreover, both end portions in the length direction of the waterproof sheet portion 30 (the first sheet piece 31 and the second sheet piece 32) are firmly sandwiched between the support portion 41 and the floor surface portion 42 in the floor portion 40. Therefore, although the floor portion 40 is only spanned between the adjacent mobile units 1 and 100 without being fixed to the adjacent mobile units 1 and 100, the displacement of the waterproof sheet portion 30 itself is regulated. Therefore, when moving between the first mobile unit 1 and the second mobile unit 100 through the passage space 20, even if a person puts a foot on the upper surface of the floor surface portion 42, the floor portion 40 is less likely to be displaced. Although not shown in the drawings, a waterproof sheet (e.g., an EPT sealer) that is set longer than the width dimension and the length dimension of the support portion 41 and the floor surface portion 42 may be sandwiched together with the waterproof sheet portion 30 between the support portion 41 and the floor surface portion 42. The width dimension of the waterproof sheet is set to be approximately the same as the width dimension of the gap between adjacent mobile units 1, 100, and the length dimension is set to be approximately the same as the dimension between the front end portion and the rear end portion in the waterproof sheet portion 30. Thereby, the gap formed between the floor portion 40 and the adjacent mobile units 1, 100 and the gap formed between the floor portion 40 and the waterproof sheet portion 30 can be closed by the waterproof sheet, so that the waterproofness at the lower end portion of the passage space 20 can be improved and the appearance can be improved by closing the gap.

[0060] 〔Regarding the connection work of the mobile unit〕 Next, the case where the first mobile unit 1 and the second mobile unit 100 are connected by the connection and surrounding means will be described.

[0061] First, the fixing outer wall materials 16, 17 are attached to the third side walls 14, 114 of the first mobile unit 1 and the second mobile unit 100. Regarding the attachment of the fixing outer wall materials 16, 17, it may be carried out on-site, but basically, it is carried out at the manufacturing stage of the first mobile unit 1 and the second mobile unit 100.

[0062] Subsequently, the angle members 21a, 22a of the first holding portion 21 and the second holding portion 22 are fixed to the fixing outer wall materials 16, 17. Regarding the fixing of the angle members 21a, 22a, it may also be carried out on-site, but it may also be carried out at the manufacturing stage of the first mobile unit 1 and the second mobile unit 100.

[0063] In addition, in this embodiment, the attachment of the fixing outer wall members 16 and 17 and the fixing of the angle members 21a and 22a are assumed to be performed at the manufacturing stage of the first mobile unit 1 and the second mobile unit 100. In that case, subsequently, the first mobile unit 1 and the second mobile unit 100 are placed on the carriage 2 and towed and transported by an automobile (not shown), and are placed at a locatable location while remaining placed on the carriage 2. At that time, the first mobile unit 1 and the second mobile unit 100 are adjacently arranged so that the first connection port 14a and the second connection port 114a face each other.

[0064] Subsequently, the first sheet piece 31 is sandwiched between the angle member 21a and the flat plate member 21b that are pre-attached and fixed by the fixing member 21c, and the first sheet piece 31 is held on the first mobile unit 1 side. Also, the second sheet piece 32 is sandwiched between the angle member 22a and the flat plate member 22b that are pre-attached and fixed by the fixing member 22c, and the second sheet piece 32 is held on the second mobile unit 100 side. Note that the operation of holding the first sheet piece 31 by the first holding portion 21 and the operation of holding the second sheet piece 32 by the second holding portion 22 can be performed from the passage space 20 side, so there is no high-place work.

[0065] Subsequently, the first sheet piece 31 and the second sheet piece 32 are connected by the waterproof fastener 33. The first sheet piece 31 and the second sheet piece 32 connected by the waterproof fastener 33 can be handled as one waterproof sheet portion 30. Both end portions in the length direction of such a waterproof sheet portion 30 are long enough to hang down below the floor portion 40 as shown in FIG. 6 (see the broken line portion), so the portion that is this long is sandwiched between the support portion 41 and the floor surface portion 42. Then, as shown in FIG. 8, the support portion 41 and the floor surface portion 42 are coupled by the wing bolt 44 so that both end portions in the length direction of the waterproof sheet portion 30 are firmly sandwiched between the support portion 41 and the floor surface portion 42. The screwing of the butterfly bolt 44 into the nut is performed by a person holding it by hand from the internal space of the support part main body 41a formed in a square tube shape.

[0066] As described above, the first mobile unit 1 and the second mobile unit 100 can be connected by the connecting and surrounding means. In this embodiment, only the attachment of the fixing outer wall materials 16 and 17 and the fixing of the angle members 21a and 22a are performed at the manufacturing stage of the first mobile unit 1 and the second mobile unit 100, but it is not limited to this. For example, the first sheet piece 31 is held in advance by the first holding part 21, and the second sheet piece 32 is held in advance by the second holding part 22. Then, the first mobile unit 1 and the second mobile unit 100 are transported. At the site, only the connection of the first sheet piece 31 and the second sheet piece 32 by the waterproof fastener 33, the arrangement of the floor part 40, and the sandwiching operation of the waterproof sheet part 30 may be performed.

[0067] 〔Regarding the effects〕 According to this embodiment, the following excellent effects can be obtained. That is, the connecting and surrounding means is provided between the adjacent mobile units 1 and 100 to connect the mobile units 1 and 100 to each other, and surrounds the opposing communication ports 14a and 114a to form the passage space 20. Therefore, the adjacent mobile units 1 and 100 can be easily connected and easily divided in a state where they can freely go back and forth between the adjacent mobile units 1 and 100, and a state where the plurality of mobile units 1 and 100 can move at any time and arbitrarily can be maintained. Furthermore, since the connecting and surrounding means has the waterproof sheet part 30 that covers at least the upper edge part 20a, one side edge part 20b, and the other side edge part 20c of the passage space 20, the waterproof sheet part 30 prevents rainwater from entering the passage space 20, and it is possible to ensure the rainproofing at the connection part between the adjacent mobile units 1 and 100.

[0068] In addition, one side edge of the waterproof sheet portion 30 is held by the first holding portion 21 provided on the side wall 14 of the first mobile unit 1, and the other side edge is held by the second holding portion 22 provided on the side wall 114 of the second mobile unit 100. Therefore, the passage space 20 can be formed simply by bridging and holding the waterproof sheet portion 30 between the side wall 14 of the first mobile unit 1 and the side wall 114 of the second mobile unit 100. As a result, adjacent mobile units 1 and 100 can be easily connected and easily divided, and a state in which a plurality of mobile units 1 and 100 can be moved at any time and arbitrarily can be maintained. Furthermore, it is possible to ensure the rainproofing at the connection portion between adjacent mobile units 1 and 100.

[0069] Further, the waterproof sheet portion 30 includes a strip-shaped first sheet piece 31 located on the side of the first mobile unit 1, a strip-shaped second sheet piece 32 located on the side of the second mobile unit 100, and a waterproof fastener 33 that connects the first sheet piece 31 and the second sheet piece 32. Therefore, the waterproof fastener 33 can connect or disconnect the first sheet piece 31 and the second sheet piece 32. Accordingly, if the first sheet piece 31 is provided on the first mobile unit 1 and the second sheet piece 32 is provided on the second mobile unit 100, when connecting adjacent mobile units 1 and 100, it is only necessary to connect the first sheet piece 31 and the second sheet piece 32 with the waterproof fastener 33, and adjacent mobile units 1 and 100 can be easily connected. Also, when separating adjacent mobile units 1 and 100, it is only necessary to separate the first sheet piece 31 and the second sheet piece 32 with the waterproof fastener 33, and adjacent mobile units 1 and 100 can be easily separated. Therefore, a state where a plurality of mobile units 1 and 100 can move at any time and arbitrarily can be maintained. Moreover, since the first sheet piece 31 and the second sheet piece 32 are connected by the waterproof fastener 33, the waterproof property between the first sheet piece 31 and the second sheet piece 32 can be improved, and rainproofing at the connection portion between adjacent mobile units 1 and 100 can be ensured.

[0070] Also, since the floor portion 40 is bridged between adjacent mobile units 1 and 100 without being fixed to the adjacent mobile units 1 and 100 and is disposed at the lower edge portion 20d of the passage space 20, adjacent mobile units 1 and 100 can be easily connected along the lower edge portion 20d of the passage space 20 and can be used for walking. Further, since the waterproof sheet portion 30 is provided from the position on one side edge portion 20b side to the position on the other side edge portion 20c side of the passage space 20 in the floor portion 40, the passage space 20 can be surrounded without gaps by the waterproof sheet portion 30 and the floor portion 40 to improve waterproofness, and rainproofing at the connection portion between adjacent mobile units 1 and 100 can be ensured.

[0071] In addition, since both end portions in the length direction of the waterproof sheet portion 30 are sandwiched between the support portion 41 and the floor surface portion 42, the waterproof property between the waterproof sheet portion 30 and the floor portion 40 can be improved, and it is possible to ensure the rainproof finish at the connection portion between adjacent mobile units 1 and 100.

[0072] In addition, since an entrance / exit 13a different from the communication port 14a is formed in at least the side wall 13 of the first mobile unit 1, even when the mutual communication ports 14a and 114a are surrounded by the connection surrounding means, it is possible to enter and exit the inside of the mobile unit 1 through the entrance / exit 13a.

[0073] In recent years, the realization of a decarbonized society by promoting carbon neutrality, which substantially reduces carbon dioxide emissions, and the achievement of the SDGs (Sustainable Development Goals) have been demanded. Also in the construction industry, efforts are underway to make buildings wooden structures with low carbon dioxide emissions. Since the unit main bodies of the mobile units 1 and 100 of the present embodiment are mostly composed of building wooden panels, they can contribute to the realization of a decarbonized society by promoting carbon neutrality and the achievement of the SDGs (Goal 7, Goal 12, Goal 13). Furthermore, since the mobile units 1 and 100 of the present embodiment can also be used as temporary housing in the event of a disaster, they can contribute to the achievement of the SDGs (Goal 11).

[0074] 〔Modification Example〕 Note that the embodiments to which the present invention is applicable are not limited to the above-described embodiments, and can be appropriately changed without departing from the gist of the present invention. Hereinafter, modification examples will be described. The following modification examples may be combined as much as possible. Also, in the following modification examples, elements common to the above-described embodiments are denoted by the same reference numerals, and the description thereof is omitted or simplified.

[0075] 〔Modification Example 1〕 The floor part 140 of this embodiment is spanned between the adjacent mobile units 1 and 100 without being fixed to the adjacent mobile units 1 and 100, and is arranged along the lower edge part 20d of the passage space 20. Such a floor part 140 includes a plurality of lower support parts 141A, an upper support part 141B, and a floor surface part 142, as shown in FIGS. 9 to 13.

[0076] In this embodiment, two lower support parts 141A are used, and the two lower support parts 141A are arranged at intervals in the front-rear direction in the gap between the mobile units 1 and 100. Such a lower support part 141A has a support part main body 141a formed in a square tube shape, and laying plates 141b provided on the lower surfaces of the front end part and the rear end part of the support part main body 141a. An operation hole 141c through which a person can insert a hand for work is formed through the bottom surface part of the square tube-shaped support part main body 141a. Above this operation hole 141c, a bolt hole 141d into which a butterfly bolt 144 for connecting the lower support part 141A and the upper support part 141B is screwed is formed. The front and rear laying plates 141b respectively protrude laterally from the left and right side surfaces of the support part main body 141a. And the parts protruding laterally in this way are placed and spanned on the upper surfaces of the left side edge part of the support base 3 of the first mobile unit 1 and the upper surface of the right side edge part of the support base 3 of the second mobile unit 100.

[0077] The upper support part 141B is formed in a square tube shape and is provided spanning two lower support parts 141A. A bolt hole corresponding to the bolt hole 141d formed on the upper surface part of the lower support part 141A is formed on the bottom surface part of this upper support part 141B. And the butterfly bolt 144 inserted from the operation hole 14c is screwed into both bolt holes 141d, and the two lower support parts 141A and the upper support part 141B are connected. And the waterproof sheet portion 30 is sandwiched between these two lower support portions 141A and upper support portion 141B. That is, of both ends in the length direction of the waterproof sheet portion 30, one end located on the side of one side edge 20b of the passage space 20 is sandwiched between one end (front end) of the front lower support portion 141A and one end (front end) of the upper support portion 141B. Further, of both ends in the length direction of the waterproof sheet portion 30, the other end located on the side of the other side edge 20c of the passage space 20 is sandwiched between the other end (rear end) of the rear lower support portion 141A and the other end (rear end) of the upper support portion 141B. Since the two lower support portions 141A and the upper support portion 141B can be joined by the wing bolt 144 as described above, both ends in the length direction of the waterproof sheet portion 30 can be firmly sandwiched between the two lower support portions 141A and the upper support portion 141B.

[0078] The positions where the waterproof sheet portion 30 has the serrated head portion and the slider portion provided in the first element portion and the second element portion are thick and hard portions in the waterproof sheet portion 30. Therefore, concave groove portions 141e that are recessed toward the center of the square tube of the upper support portion 141B are formed on the bottom surface portions at both ends in the length direction of the upper support portion 141B. When both ends in the length direction of the waterproof sheet portion 30 are sandwiched between the two lower support portions 141A and the upper support portion 141B, the thick and hard portions are arranged in the concave groove portions 141e. Thereby, the first sheet piece 31 and the second sheet piece 32 can be firmly sandwiched between the two lower support portions 141A and the upper support portion 141B. Note that the connection between the lower support portion 141A and the upper support portion 141B by the wing bolt 144 is performed at a position where the terminals of the first sheet piece 31 and the second sheet piece 32 do not reach. Furthermore, although the concave groove portions 141e are formed on the bottom surface portion of the upper support portion 141B, they may be formed on the upper surface portion of the lower support portion 141A. Also, instead of the concave groove portions 141e, slits (notches) capable of accommodating the thick and hard portions described above may be formed.

[0079] On the upper surface portions at both ends in the longitudinal direction of the upper support portion 141B, bolt holes 141f into which the butterfly bolts 144 for coupling the floor surface portion 142 are screwed are formed. As shown in FIG. 11, the width dimension of the floor surface portion 142 is set to be approximately the same as the width dimension in the gap between adjacent mobile units 1, 100. Also, the length dimension is set to be approximately the same as the length dimension in the gap between adjacent mobile units 1, 100 (for example, the interval dimension between the first holding portions 21 and the interval dimension between the second holding portions 22). As a result, the floor surface portion 142 is arranged so that a gap is not formed as much as possible between adjacent mobile units 1, 100.

[0080] Also, on the upper surface portions at both ends in the longitudinal direction of the floor surface portion 142, bolt holes 142a into which the butterfly bolts 144 are screwed are formed. These bolt holes 142a correspond to the bolt holes 141f formed on the upper surface portion of the upper support portion 141B, and the floor surface portion 142 can be coupled and fixed to the upper support portion 141B by the butterfly bolts 144. Also, the bolt holes 142a are recessed so that the heads of the butterfly bolts 144 can be accommodated. Furthermore, as shown in FIGS. 12 and 13, the floor surface portion 142 is placed on the lower support portion 141A and the upper support portion 141B, and the height position of the upper surface is substantially equal to the height of the lower edge portion of the sash constituting the first communication port 14a and the second communication port 114a. As a result, when moving between the first mobile unit 1 and the second mobile unit 100, a step is less likely to occur, making it easier to pass.

[0081] According to this modification example, since both end portions in the length direction of the waterproof sheet portion 30 are sandwiched between the lower support portion 141A and the upper support portion 141B, both end portions in the length direction of the waterproof sheet portion 30 will be held at a position deeper than the portion closer to the upper surface of the floor portion 140 (the upper surface of the floor surface portion 142). Moreover, since the floor surface portion 142 has longitudinal and lateral dimensions close to the width dimension and the length dimension in the gap between adjacent mobile units 1, 100, both end portions in the length direction of the lower support portion 141A, the upper support portion 141B, and the waterproof sheet portion 30 are effectively shielded by the floor surface portion 142, and it looks good. Moreover, since it is possible to suppress a foot from entering the gap during passage, it can contribute to an improvement in safety. Furthermore, since the lower support portion 141A and the upper support portion 141B are laminated and the floor surface portion 142 is disposed thereon, it becomes easy to dispose the floor surface portion 142 at a high position. Therefore, it is easy to dispose the height position of the upper surface of the floor surface portion 142 at substantially the same height as the lower edge portion of the sash constituting the first communication port 14a and the second communication port 114a.

[0082] [Modification Example 2] In the above-described embodiment, the adjacent mobile units 1, 100 are arranged such that their long side portions are adjacent to each other, but the present invention is not limited to this. For example, in the adjacent mobile units 1, 100 in this modification example, their short side portions are adjacent to each other. That is, the first mobile unit 1 and the second mobile unit 100 are arranged adjacent to each other in a state where the first communication port 14a provided at one end surface in the length direction of the first mobile unit 1 and the second communication port 114a provided at the other end surface in the length direction of the second mobile unit 100 face each other (are directly opposed). Applying this, for example, four or more mobile units may be arranged and connected in a lattice shape, or three or more mobile units may be arranged and connected in an L shape, a T shape, or a cross shape.

[0083] Furthermore, the adjacent mobile units 1, 100 in this modification example may be arranged such that the long side portion of one mobile unit is adjacent to the short side portion of the other mobile unit. In this case, the communication port provided in the long side portion of one mobile unit and the communication port provided in the short side portion of the other mobile unit will be arranged in a state where they face each other.

[0084] Furthermore, in the above-described embodiment, the adjacent mobile units 1, 100 are in a state where the front and rear positions are aligned when the first communication port 14a and the second communication port 114a face each other, but it is not limited to this. For example, the adjacent mobile units 1, 100 in this modification example are in a state where they are offset in the front and rear positions and arranged in a staggered pattern when the first communication port 14a and the second communication port 114a face each other.
