Description

[Technical Field]

[0001] The present invention relates to a connection structure for a mobile unit. [Background technology]

[0002] Conventionally, mobile units that can be easily relocated or installed have been widely known as container houses, trailer houses, camper vans, etc. Demand for mobile units has been increasing in recent years, with some being permanently installed as residences, stores, or offices, others being used as temporary accommodations, and others being used as temporary housing in the event of natural disasters. On the other hand, since such mobile units are towed and transported by automobiles, they must be sized to fit within legal regulations (such as the Road Transport Vehicle Act), but this poses the problem of limited internal space. Therefore, as disclosed in Patent Document 1, for example, multiple mobile units may be connected to each other to enable movement between them in order to expand the internal space. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 10-305751 Summary of the Invention [Problem to be solved by the invention]

[0004] However, depending on how they are used, mobile units may not be considered buildings under the Building Standards Act, and in such cases, multiple mobile units must be able to be easily connected to one another and easily separated (separated) without the use of special tools, etc., so that multiple mobile units can be maintained in a state where they can be moved at any time and as desired. Furthermore, when connecting multiple mobile units, it is necessary to prevent the infiltration of rainwater, etc., so it is required to ensure that the connecting points are waterproof.

[0005] The present invention has been made in consideration of the above circumstances, and its object is to make it possible to easily connect and separate multiple mobile units, thereby maintaining a state in which the multiple mobile units can be moved at any time and as desired, and further to ensure weatherproofing at the connection points between the multiple mobile units. [Means for solving the problem]

[0006] In the invention described in claim 1, as shown in, for example, FIGS. 1 to 12, a plurality of mobile units 1,100 are arranged adjacent to each other with their communication openings 14a, 113a facing each other, a connecting and surrounding means that is provided between adjacent mobile units 1,100 to connect the mobile units 1,100 and surrounds the area between the opposing communication openings 14 a, 113 a to form a passage space 20; The connecting and surrounding means is a waterproof sheet portion 30 covering at least the upper edge portion 20a, one side edge portion 20b, and the other side edge portion 20c of the passage space 20; a floor portion (40) that is not fixed to the adjacent mobile units (1,100), is bridged between the adjacent mobile units (1,100), is placed at the lower edge of the passage space (20), and holds the lower ends of both side edges of the waterproof sheet portion (30); The floor portion 40 is a support portion 41 disposed between adjacent mobile units 1,100; a floor portion 42 that is detachably fixed to the upper surface of the support portion 41 and forms the floor surface of the passage space 20; a first fixing member (44) for fixing the floor surface portion (42) to the support portion (41); The first fixing member 44 is provided from top to bottom from the floor portion 42 toward the support portion 41, thereby fixing the floor portion 42 to the support portion 41.

[0007] According to the invention described in claim 1, the connecting and surrounding means is provided between adjacent mobile units 1,100 to connect the mobile units 1,100 to each other, and also surrounds the space between the opposing communication openings 14a, 113a to form an aisle space 20, so that adjacent mobile units 1,100 can be easily connected to each other in a state where they can move freely between the adjacent mobile units 1,100, and can also be easily separated, thereby maintaining a state in which multiple mobile units 1,100 can move at any time and as desired. Furthermore, the connecting and enclosing means has a waterproof sheet portion 30 that covers at least the upper edge portion 20a, one side edge portion 20b, and the other side edge portion 20c of the passage space 20, so that the waterproof sheet portion 30 can prevent rainwater from entering the passage space 20 at a position above the floor portion 40. Furthermore, the connecting and enclosing means is not fixed to adjacent mobile units 1,100 but is bridged between the adjacent mobile units 1,100 and is positioned at the lower edge of the aisle space 20, and has a floor section 40 that holds the lower ends of both side edges of the waterproof sheet section 30.This floor section 40 allows adjacent mobile units 1,100 to be easily connected along the lower edge section 20d of the aisle space 20, making it usable for walking, while the waterproof sheet section 30 and the floor section 40 surround the aisle space 20 without any gaps, improving waterproofing and ensuring weatherproofing at the connection points between adjacent mobile units 1,100. Moreover, the floor section 40 comprises support sections 41 arranged to span between adjacent mobile units 1,100, floor surface sections 42 that are detachably fixed to the upper surfaces of the support sections 41 and form the floor surface of the passage space 20, and first fixing members 44 for fixing the floor surface section 42 to the support sections 41, and the first fixing members 44 are provided from top to bottom from the floor surface section 42 toward the support sections 41, thereby fixing the floor surface section 42 to the support sections 41, so that the work of fixing the floor surface section 42 to the support sections 41 can be performed from above. In other words, since the work of fixing the floor surface section 42 to the support sections 41 can be performed within the passage space 20, it is possible to fix and release the floor surface section 42 to the support sections 41 more easily than, for example, when fixing the floor surface section 42 to the support sections 41, compared to when the work is performed from below. This allows adjacent mobile units 1,100 to be more easily connected to each other in a state where they can move freely between the adjacent mobile units 1,100, and also allows them to be more easily separated, so that multiple mobile units 1,100 can be maintained in a state where they can move at any time and as desired.

[0008] The invention described in claim 2 is, for example, as shown in Figs. 7 to 12, in the connection structure of the mobile unit 1,100 described in claim 1, The floor surface portion 42 is a base portion 420 placed on the support portion 41 and fixed to the support portion 41 by the first fixing member 44; a floor finishing part (430) that is detachably fixed to the upper surface of the base part (420) and forms the floor surface of the passage space (20); a second fixing member (440) for fixing the floor finishing portion (430) to the base portion (420); The second fixing material 440 is characterized in that it is provided from top to bottom from the floor finishing portion 430 toward the base portion 420, thereby fixing the floor finishing portion 430 to the base portion 420.

[0009] According to the invention of claim 2, the floor surface portion 42 has a base portion 420 placed on the support portion 41 and fixed to the support portion 41 by first fixing members 44, a floor finishing portion 430 detachably fixed to the upper surface of the base portion 420 to form the floor surface of the passage space 20, and second fixing members 440 for fixing the floor finishing portion 430 to the base portion 420, and the second fixing members 440 are provided from top to bottom from the floor finishing portion 430 toward the base portion 420, thereby fixing the floor finishing portion 430 to the base portion 420, so that the work of fixing the floor finishing portion 430 to the base portion 420 can be performed from above. In other words, since the work of fixing the floor finishing portion 430 to the base portion 420 can be performed within the passage space 20, it is possible to fix and release the floor finishing portion 430 to the base portion 420 more easily than if the work of fixing the floor finishing portion 430 to the base portion 420 was performed from below. This allows adjacent mobile units 1,100 to be more easily connected to each other in a state where they can move freely between the adjacent mobile units 1,100, and also allows them to be more easily separated, so that multiple mobile units 1,100 can be maintained in a state where they can move at any time and as desired.

[0010] The invention described in claim 3 is, for example, as shown in Figs. 7 to 12, in the connection structure of the mobile unit 11, 100 described in claim 1, The support portion 41 is An installation section 400 that spans between adjacent mobile units 1,100; a support body 410 that is mounted on and attached to the erection portion 400 and has an upper surface to which the floor portion 42 is fixed by the first fixing member 44; The support portion main body 410 is characterized in that it is slidable on the upper surface of the installation portion 400 along the direction in which the installation portion 400 is installed between the adjacent mobile units 1,100.

[0011] According to the invention of claim 3, the support section 41 has an installation section 400 that bridges between adjacent mobile units 1,100, and a support section main body 410 that is mounted on and attached to the installation section 400 and has a floor section 42 fixed to its upper surface by first fixing members 44, and the support section main body 410 is slidable on the upper surface of the installation section 400 in the direction in which the installation section 400 bridges between adjacent mobile units 1,100, so that the position of the support section main body 410 can be adjusted according to the distance between adjacent mobile units 1,100. This allows the position of the floor section 42 that forms the floor surface of the aisle space 20 to be located in the middle part between adjacent mobile units 1,100, thereby improving walkability within the aisle space 20. Furthermore, since the floor portion 40 including the floor surface portion 42 holds the waterproof sheet portion 30, it is possible to prevent the waterproof sheet portion 30 from being twisted to one side of the adjacent mobile units 1,100, thereby contributing to ensuring weatherproofing at the connection points between the adjacent mobile units 1,100.

[0012] The invention described in claim 4 is, for example, as shown in Figs. 7 to 12, in the connection structure of the mobile unit 1,100 described in claim 1, A sheet-like sealing material 43 is sandwiched between the support portion 41 and the floor surface portion 42, The sealing material 43 is characterized in that it is bridged between the adjacent mobile units 1,100.

[0013] According to the invention described in claim 4, a sheet-like sealing material 43 is sandwiched between the support portion 41 and the floor portion 42, and the sealing material 43 is bridged between adjacent mobile units 1,100, so that the portion of the floor portion 40 located above the support portion 41 can be protected by the sealing material 43. This contributes to ensuring weatherproofing at the portion of the connection portion between adjacent mobile units 1,100 located above the support portion 41.

[0014] The invention described in claim 5 is, for example, as shown in FIG. 8, in the connection structure of the mobile unit 1,100 described in claim 4, A first insulating material 45 is filled in the gap on the upper surface of the sealing material 43 and between the floor portion 42 and the mobile unit 1,100 adjacent to the floor portion 42.

[0015] According to the invention of claim 5, the first insulating material 45 is filled in the gap on the upper surface of the sealing material 43 and between the floor surface portion 42 and the mobile unit 1,100 adjacent to the floor surface portion 42, thereby improving the thermal insulation of the floor portion 40 of the passage space 20. Furthermore, since the first insulating material 45 is filled, the floor surface portion 42 is less likely to shift toward one of the adjacent mobile units 1,100, which prevents the waterproof sheet portion 30 held by the floor portion 40 from being twisted toward one of the adjacent mobile units 1,100, and contributes to ensuring weatherproofing at the connection points between the adjacent mobile units 1,100.

[0016] The invention described in claim 6 is, for example, as shown in Figs. 4 to 7, in the connection structure of the mobile unit 1,100 described in claim 1, The waterproof sheet portion 30 is an inner sheet portion 31 located on the communication opening 14a, 114a side; an outer sheet portion 32 located outside the inner sheet portion 31, The inner sheet portion 31 and the outer sheet portion 32 are configured to be separable between the first mobile unit 1 side and the second mobile unit 100 side, respectively. A second insulating material 35 is filled between the inner sheet portion 31 and the outer sheet portion 32.

[0017] According to the invention described in claim 6, the waterproof sheet portion 30 has an inner sheet portion 31 located on the communication openings 14a, 114a side, and an outer sheet portion 32 located outside the inner sheet portion 31, and the inner sheet portion 31 and the outer sheet portion 32 are configured to be easily separable to the first mobile unit 1 side and the second mobile unit 100 side, respectively, so that adjacent mobile units 1,100 can be easily connected to each other in a state where they can move freely between the adjacent mobile units 1,100, and can also be easily separated, thereby maintaining a state in which multiple mobile units 1,100 can be moved at any time and as desired. Furthermore, since the second insulating material 35 is filled between the inner sheet portion 31 and the outer sheet portion 32, it is possible to improve the thermal insulation in the portion of the aisle space 20 that is located above the floor portion 40. This makes it easier to maintain a comfortable thermal environment in the internal spaces of the first mobile unit 1 and the second mobile unit 100 that are adjacent to the aisle space 20. [Effects of the Invention]

[0018] According to the present invention, a plurality of mobile units can be easily connected to one another and can also be easily separated, so that the plurality of mobile units can be maintained in a state in which they can be moved at any time and as desired, and further, weatherproofing can be ensured at the connection points between the plurality of mobile units.

DETAILED DESCRIPTION OF THE INVENTION

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

[0021] 1 etc., reference numeral 1,100 denotes a mobile unit. The mobile unit 1,100 of this embodiment is a trailer house, which is placed on a dolly 2 and towed and transported by an automobile (not shown), and is placed in a suitable location while still on the dolly 2.

[0022] Furthermore, the mobile unit 1,100 has passed vehicle inspection and is sized within legal regulations (Building Standards Act, Road Transport Vehicle Act) (Safety Standards Article 2 limits: vehicle width within 2.5 m, vehicle length within 12 m, vehicle height within 3.8 m). This allows the mobile unit 1,100 to be legally moved on public roads. However, with special permission, the mobile unit may be sized larger than the limits. Additionally, the mobile unit 1100 shall meet all criteria required for placement at a fixed location.

[0023] The cart 2 is also called a chassis, and includes a support base 3 to which wheels 3a are attached, and a plurality of support legs (not shown) provided on the support base 3 so as to be detachable. The box-shaped unit body of the mobile unit 1,100 is placed on and integrated with the support base 3. In addition, a connecting portion 3b that protrudes forward and is connected to an automobile is integrally formed at the front end of the support base 3. The support legs are provided at six locations in total: the four corners of the support base 3 and two locations near the wheels 3a (the center of the support base 3 in the longitudinal direction). The support legs are jack devices that can be manually raised and lowered at the locations 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 placed. In this embodiment, the mobile units 1 are arranged in an L-shape in plan view, with the rear end of one mobile unit 100 (hereinafter, second mobile unit 100) abutting against the left side surface of the front end of the other mobile unit 1 (hereinafter, first mobile unit 1). However, strictly speaking, a small gap is formed between these mobile units 1,100. The width of the gap is set to, for example, about 100 to 300 mm. Furthermore, the length of the gap between the mobile units 1,100 is equal to the length in the left-right width direction at the rear end of the second mobile unit 100. Furthermore, the height of the gap between the mobile units 1,100 is equal to the length in the height direction of the mobile units 1,100. Moreover, such mobile units 1,100 are arranged with the communication ports 14a and 113a formed on the opposing side surfaces facing each other (in a parallel positional relationship, facing directly in front of each other).

[0025] Furthermore, at least one of the mobile units 1, 100 has an entrance 113a that is different from the communication openings 14a, 113a. In this embodiment, as shown in Figures 1 and 2, an entrance 115a is formed in the fourth side wall 115 of the second mobile unit 100. An entrance door 115b is provided at the entrance 115a, and this entrance 115a can be used as an entrance.

[0026] [Mobile unit configuration] Next, the configuration of the mobile unit 1100 will be described in detail. The mobile unit 1,100 of this embodiment, which is a trailer house, is configured to include a dolly 2, and the box-shaped unit main body placed on the support base 3 of the dolly 2 will be described below. In this 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 Figures 4, 5, etc., the unit bodies of the first mobile unit 1 and the second mobile unit 100 are formed in a box shape, with their outer shells consisting of floors 10, 110 that are placed on and integrated with the support base 3, a roof 11, 111, and four side walls 12-15, 112-115 that are provided between the floors 10, 110 and the roof 11, 111. Such a unit body is formed into a rectangular parallelepiped shape that is long in one direction (front-rear direction) and short in the other direction (left-right direction) in a plan view. In the case of the first mobile unit 1 arranged on the L side in a plan view, it is formed to be long in the north-south direction and short in the east-west direction in a plan view. On the other hand, in the case of the second mobile unit 100, it is formed to be long in the east-west direction and short in the north-south direction in a plan view.

[0028] The floors 10, 110 are long in one direction (front-to-back) and short in the other direction (left-to-right), forming a rectangle in plan view, and constitute the entire surface of the floors 10, 110 in the space within the first mobile unit 1 and the second mobile unit 100. The floor bodies of the floors 10 and 110 are made of hollow architectural wood panels. A floor finishing material (for example, flooring material) is provided on the upper surface of the floor body, and the hollow interior is filled with a heat insulating material.

[0029] The roof 11 of the first mobile unit 1 is a shed roof that is higher on the side (west side) of the adjacent second mobile unit 100 and lower on the opposite side (east side). The roof 111 of the second mobile unit 100 is a single-pitch roof that is higher on the north side and lower on the south side in a direction parallel to the length direction of the adjacent first mobile unit 1. Therefore, when the first mobile unit 1 and the second mobile unit 100 are arranged adjacent to each other in an L-shape in plan view as described above, the adjacent mobile unit 1,1100 is not arranged in the roof flow direction, which is preferable because rainwater flowing on the roof 11,111 does not flow toward the adjacent mobile unit 1,1100. The roof body of the roofs 11, 111 is made of hollow architectural wood panels. A roofing material (e.g., Galvalume Steel Roofing (registered trademark)) is provided on the surface of the roof body, and the hollow space is filled with a heat insulating material. Additionally, ceiling materials (for example, decorative ceiling panels) are attached to the underside of the roof body. Because the roofs 11, 111 are shed roofs, the ceiling appears to be a sloped ceiling when viewed from inside the unit body. However, this is not limited to this, and a horizontal ceiling made of rafters, ceiling materials, etc. may also be formed below the roof body.

[0030] The first mobile unit 1 has four side walls, namely, 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 on one end side (front end side / south side) of the floor 10 in the length direction. The second side wall 13 is provided on the other end side (rear end side / north side) of the floor 10 in the length direction. The third side wall 14 is provided between the other end (left end, west side) of the first side wall 12 in the width direction and the other end (left end, west side) of the second side wall 13 in the width direction. The fourth side wall 15 is provided between one end (right end, east side) of the first side wall 12 in the width direction and one end (right end, east side) of the second side wall 13 in the width direction. 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 side surfaces of the unit body and have a long width dimension (dimension in the front-to-back direction). The four side walls 12 to 15 are made of hollow wooden architectural panels. Exterior wall materials (e.g., galvalume steel exterior walls or siding) are provided on the outdoor side of the wall body, and interior wall materials (e.g., gypsum board) and wall finishing materials (e.g., wallpaper) are provided on the indoor side, and the hollow interior is filled with heat insulating material.

[0031] Of 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 on the front end side (south side) of the third side wall 14, which is located on the second mobile unit 100 side. A first door 14b for opening and closing the first communication opening 14a is provided on the third side wall 14. The first door 14b is a single-wing door that opens inward toward the interior space of the first mobile unit 1.

[0032] The second mobile unit 100 has four side walls, namely, a first side wall 112, a second side wall 113, a third side wall 114, and a fourth side wall 115. The first side wall 112 is provided on one end side (front end side / west side) of the floor 110 in the length direction. The second side wall 113 is provided on the other end side (rear end side / east side) of the floor 110 in the length direction. The third side wall 114 is provided between the other end (left end, north side) of the first side wall 112 in the width direction and the other end (left end, north side) of the second side wall 113 in the width direction. The fourth side wall 115 is provided between one widthwise end (right end, south side) of the first side wall and one widthwise end (right end, south side) of the second side wall 113 . As described above, the positional relationship between the four side walls 112 to 115 of the second mobile unit 100 is not symmetrical to the positional relationship between the four side walls 12 to 15 of the first mobile unit 1.

[0033] The four side walls 112 to 115 are made of hollow wooden architectural panels. An exterior wall material (e.g., galvalume steel exterior wall or siding material) is provided on the outdoor side of the wall body, and an interior wall material (e.g., gypsum board) and a wall finishing material (e.g., wallpaper) are provided on the indoor side, and the hollow interior is filled with heat insulating material.

[0034] Of the four side walls 112 to 115 of the second mobile unit 100, the second side wall 113 located on the first mobile unit 1 side is formed with a second communication opening 113a, which is an opening for people to pass through. A second door 113b for opening and closing the second communication opening 113a is provided on the second side wall 113. The second door 113b is a single-wing door that opens inward toward the internal space of the second mobile unit 100.

[0035] As described above, the fourth side wall 115 of the second mobile unit 100 is formed with a doorway 115a, which is an opening for people to pass through. This doorway 115a faces not toward the first mobile unit 1 but toward the outdoor space. Therefore, this doorway 115a functions as an entrance door for the second mobile unit 100. Furthermore, the fourth side wall 115 is provided with an entrance door 115b, which is a door for opening and closing the doorway 115a. This allows people to enter and exit between the interior space of the second mobile unit 100 and the outdoor space through the doorway 115a. In addition, since the unit body of the second mobile unit 100 is placed at a certain height position by the dolly 2, the height position of the entrance / exit 115a also becomes high. For this reason, elevator facilities such as stairs and slopes are installed on the outdoor side of the entrance / exit 115a without being fixed to the second mobile unit 100.

[0036] The first mobile unit 1 and second mobile unit 100 configured as described above are adjacent to each other in a place where they can be placed, and are arranged with the communication openings 14a, 113a formed in the opposing side walls 14, 113 facing each other directly (in a parallel positional relationship and facing directly front). The first communication opening 14a is formed on the front end side of the third side wall 14 that forms the left side surface of the first mobile unit 1, and the second communication opening 113a is formed on the second side wall 113 that forms the rear end surface of the second mobile unit 100. Therefore, when the first mobile unit 1 and the second mobile unit 100 are lined up so that the communication openings 14a, 113a face each other directly, the first mobile unit 1 and the second mobile unit 100 are arranged to form an L shape in a plan view.

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

[0038] As shown in Figures 3 to 12, the connecting and surrounding means is provided between adjacent mobile units 1,100 to connect the mobile units 1,100 to each other, and also surrounds the space between the first communication opening 14a on the opposing first mobile unit 1 side and the second communication opening 113a on the opposing second mobile unit 100 side to form an aisle space 20. In other words, the space enclosed by the connecting and enclosing means serves as a passage space 20 for movement between the first mobile unit 1 and the second mobile unit 100.

[0039] The passage space 20 has an upper edge 20a, one side edge 20b, another side edge 20c, and a lower edge 20d defined by the connecting enclosing means. The upper edge portion 20a refers to a portion located above the first communication opening 14a and the second communication opening 114a, and is formed in a mountain shape. The one side edge 20b refers to a linear portion located between the south end of the upper edge 20a and the south end of the lower edge 20d. The other side edge 20c refers to a linear portion located between the north end of the upper edge 20a and the north end of the lower edge 20d. The lower edge 20d refers to a linear portion located between the lower end of the one side edge 20b and the lower end of the other side edge 20c.

[0040] The connecting and enclosing means that defines such an aisle space 20 comprises a waterproof sheet portion 30 and a floor portion 40, and further comprises a first retaining portion 21 and a second retaining portion 22 as means for holding the waterproof sheet portion 30. The waterproof sheet portion 30 of this embodiment has an inner sheet portion 31 located on the communication openings 14a, 113a side, and an outer sheet portion 32 located outside the inner sheet portion 31. Therefore, the first retaining portion 21 and the second retaining portion 22 that hold the waterproof sheet portion 30 also have retaining portions 21A, 22A (first inner retaining portion 21A, second inner retaining portion 22A) located on the inside, and retaining portions 21B, 22B (first outer retaining portion 21B, second outer retaining portion 22B) located on the outside, respectively.

[0041] The inner sheet portion 31 of the waterproof sheet portion 30 comprises a first inner sheet piece 311 located on the first mobile unit 1 side, a second inner sheet piece 312 located on the second mobile unit 100 side, and an inner waterproof zipper 313 connecting the first inner sheet piece 311 and the second inner sheet piece 312.

[0042] The outer sheet portion 32 of the waterproof sheet portion 30 comprises a first outer sheet piece 321 located on the first mobile unit 1 side, a second outer sheet piece 322 located on the second mobile unit 100 side, and an outer waterproof fastener 323 connecting the first outer sheet piece 321 and the second outer sheet piece 322.

[0043] The inner sheet portion 31 and the outer sheet portion 32 are made of a highly waterproof fabric, such as tent fabric. The inner waterproof zipper 313 and the outer waterproof zipper 323 each have a waterproof first tape portion welded to the sheet pieces 311, 321 (first inner sheet piece 311, first outer sheet piece 321) on the first mobile unit 1 side, a waterproof second tape portion welded to the sheet pieces 312, 322 (second inner sheet piece 312, second outer sheet piece 322) on the second mobile unit 100 side, a first element portion provided on the edge of the first tape portion and having a coupling head, a second element portion provided on the edge of the second tape portion and having a coupling head, and a slider portion (not shown) that engages and disengages the first element portion and the second element portion. The first element portion and the second element portion are shaped to exhibit waterproof performance when they are engaged and connected to each other. The slider portion is attached to either the sheet pieces 311 and 321 on the first mobile unit 1 side or the sheet pieces 312 and 322 on the second mobile unit 100 side. The slider portion is arranged on the aisle space 20 side so that the sheet pieces 311, 321 on the first mobile unit 1 side and the sheet pieces 312, 322 on the second mobile unit 100 side can be connected and disconnected from the aisle space 20 side.

[0044] In addition, the sheet pieces 311, 321 (first inner sheet piece 311, first outer sheet piece 321) on the first mobile unit 1 side are provided with a strip-shaped watertight material 33 arranged along the front and back of the edge (base end) on the side held by the first holding portion 21 (first inner holding portion 21A, first outer holding portion 21B), and a plurality of eyelet portions 34 that form through holes into which the fixing member 25 (bolt) is inserted. The watertight material 33 is, for example, Eptsealer. The multiple eyelets 34 are provided so as to border through holes that penetrate the sheet pieces 311, 321 on the first mobile unit 1 side and the front and back watertight materials 33. The multiple eyelets 34 are arranged at predetermined intervals along the edges of the sheet pieces 311, 321 on the first mobile unit 1 side.

[0045] Similarly, the sheet pieces 312, 322 (second inner sheet piece 312, second outer sheet piece 322) on the second mobile unit 100 side also have a strip-shaped watertight material 33 arranged along the front and back of the edge portion of the side held by the second holding portion 22 (second inner holding portion 22A, second outer holding portion 22B), and a plurality of eyelet portions 34 that form through holes into which the fixing member 25 (bolt) is inserted.

[0046] The first holding portion 21 holds the inner sheet portion 31 (first inner sheet piece 311) and the outer sheet portion 32 (first outer sheet piece 321) provided on the first mobile unit 1 side, and is equipped with a first inner holding portion 21A, a first outer holding portion 21B, a base plate portion 23, a sheet metal cover 24, and a fixing member 25.

[0047] The base plate portion 23 is a plate portion that serves as a fixing base for fixing the first inner holding portion 21A and the first outer holding portion 21B, and is attached to the third side wall 14 of the first mobile unit 1 along the peripheral portion (upper edge and both side edges) of the first connecting opening 14a formed in the third side wall 14. The sheet metal cover 24 is a thin metal plate that covers the base plate portion 23. The first inner holding portion 21A and the first outer holding portion 21B are fixed to the base plate portion 23 via this sheet metal cover 242 with screws or the like.

[0048] The first inner retaining portion 21A holds the first inner sheet piece 311, which is the inner sheet portion 31 on the first mobile unit 1 side, and is fixed to a base plate portion 23 attached to the third side wall 14 of the first mobile unit 1. The first inner retaining portion 21A has a pair of angle members, which are metal fittings with an L-shaped cross section. One side of the pair of angle members that constitutes the L shape is a fixing piece that is fixed to the base plate portion 23, and the other side that constitutes the L shape is a holding piece that holds the first inner sheet piece 311. The fixing piece has through holes formed at a predetermined interval, through which fixing materials such as screws are passed to fix the angle member to the base plate portion 23. The holding piece also has through holes formed in it that match the positions of the multiple eyelet portions 34 (through holes) in the first inner sheet piece 311, so that the fixing member 25 can be passed through. In other words, the base end portion of the first inner sheet piece 311 (the edge portion on the side where the watertight material 33 and the eyelet portion 34 are located) is sandwiched between the holding pieces of the pair of angle members and can be fixed with the fixing member 25.

[0049] The pair of angle members are made into multiple parts so that the fixing work can be divided into multiple steps. 3, the passage space 20 of this embodiment has an upper edge 20a formed in a mountain shape, and one side edge 20b and the other side edge 20c formed in a straight line. The parts of the angle member a that define the shape of such passage space 20 include a mountain-shaped part at the apex, a curved part that forms the curved portion between the upper edge 20a and one side edge 20b and the other side edge 20c, straight parts that connect the mountain-shaped part to the curved parts on both sides, and a plurality of straight parts that form the one side edge 20b and the other side edge 20c.

[0050] The fixing member 25 comprises a pair of angle members, a bolt inserted into a through hole (grommet portion 34) in the first inner sheet piece 311, a nut into which the tip of the bolt's shaft is screwed, and a washer provided between each of the bolt and nut and the pair of angle members.

[0051] The first outer holding portion 21B holds the first outer sheet piece 321, which is the outer sheet portion 32 on the first mobile unit 1 side, and is fixed to a base plate portion 23 attached to the third side wall 14 of the first mobile unit 1. The first outer retaining portion 21B includes a first angle member attached to the surface of the base plate portion 23 and a second angle member inserted into a slit 23a formed in the outer end of the base plate portion 23. These angle members are L-shaped, with one side serving as a fixing piece that is fixed to the base plate portion 23 and the other side serving as a holding piece for holding the first outer sheet piece 321. The fixing piece has through holes formed at predetermined intervals through which fixing materials such as screws are passed to fix the angle member to the base plate portion 23. The holding piece also has through holes formed in it that match the positions of the multiple eyelet portions 34 (through holes) in the first outer sheet piece 321, allowing the fixing member 25 to pass through. In other words, the base end of the first outer sheet piece 321 (the edge on the side where the watertight material 33 and eyelet portion 34 are located) is sandwiched between the holding pieces of these angle members and fixed with the fixing member 25.

[0052] Similar to the pair of angle members in the first inner holding portion 21A, these angle members are also made into a plurality of parts so that the fixing operation can be divided into a plurality of steps. The fixing member 25 used to fix the first outer sheet piece 321 also includes a bolt, a nut, and a washer.

[0053] The second holding portion 22 holds the inner sheet portion 31 (second inner sheet piece 312) and the outer sheet portion 32 (second outer sheet piece 322) provided on the second mobile unit 100 side, and is equipped with a second inner holding portion 22A, a second outer holding portion 22B, a base plate portion 23, a sheet metal cover 24, and a fixing member 25.

[0054] The base plate portion 23 and the sheet metal cover 24 are attached to the second side wall 113 of the second mobile unit 100 along the peripheral edges (upper edge and both side edges) of the second communication opening 113a formed in the second side wall 113. The sheet metal cover 24 covers the base plate portion 23. The base plate portion 23 and the sheet metal cover 24 on the second mobile unit 100 side are provided symmetrically to the base plate portion 23 and the sheet metal cover 24 on the first mobile unit 1 side.

[0055] The second inner retaining portion 22A holds the second inner sheet piece 312, which is the inner sheet portion 31 on the second mobile unit 100 side, and is fixed to a base plate portion 23 attached to the second side wall 113 of the second mobile unit 100. Such a second inner holding portion 22A has a configuration symmetrical to the first inner holding portion 21A provided on the first mobile unit 1 side. That is, it has a pair of angle members, which are metal fittings with an L-shaped cross section, and is configured so that the second inner sheet piece 312 can be sandwiched between the holding pieces of the pair of angle members and fixed with the fixing member 25.

[0056] The second outer holding portion 22B holds the second outer sheet piece 322, which is the outer sheet portion 32 on the second mobile unit 100 side, and is fixed to a base plate portion 23 attached to the second side wall 113 of the second mobile unit 100. Such second outer holding portion 22B has a configuration symmetrical to the first outer holding portion 21B provided on the side of the first mobile unit 1. That is, it has a first angle member attached to the surface of the base plate portion 23, and a second angle member attached so as to be inserted into the slit 23a of the base plate portion 23, and is configured so that the second outer sheet piece 322 can be sandwiched between the holding pieces of these angle members and fixed with the fixing member 25.

[0057] The inner sheet portion 31 and the outer sheet portion 32 of the waterproof sheet portion 30 are arranged between adjacent mobile units 1,100, with the edge portion on the first mobile unit 1 side held by the first holding portion 21 (first inner holding portion 21A, first outer holding portion 21B) and the edge portion on the second mobile unit 100 side held by the second holding portion 22 (second inner holding portion 22A, second outer holding portion 22B). A heat insulating material 35 (second heat insulating material) such as glass wool is filled between the inner sheet portion 31 and the outer sheet portion 32. The range in which this waterproof sheet portion 30 covers the passage space 20 is the upper edge 20a, one side edge 20b, and the other side edge 20c of the passage space 20. Therefore, the range in which the heat insulating material 35 is filled is also the range in which the upper edge 20a, one side edge 20b, and the other side edge 20c of the passage space 20 are filled. The lower edge 20d of the aisle space 20 is covered by a floor portion 40.

[0058] The floor section 40 is not fixed to the adjacent mobile units 1,100, but is bridged between the adjacent mobile units 1,100 and is disposed at the lower edge 20d of the passage space 20. As shown in Figures 7 to 12, this floor section 40 includes a support section 41 that bridges between the adjacent mobile units 1,100, a floor surface section 42 that is detachably fixed to the upper surface of the support section 41, a sealing material 43 that is sandwiched between the support section 41 and the floor surface section 42, and a first fixing member 44 that fixes the floor surface section 42 to the support section 41.

[0059] In this embodiment, two (a pair) support parts 41 are used, and the two support parts 41 are arranged at a distance from each other in the width direction (north-south direction) of the passage space 20 in the gap between the mobile units 1,100. Such a support section 41 has a pair of bridge sections 400 that are installed to span between adjacent mobile units 1,100, and a support section main body 410 that is formed in a box shape and is installed across the pair of bridge sections 400.

[0060] The bridge portion 400 is a rectangular metal plate, and has a through-hole 400a formed in the center thereof, penetrating the bridge portion 400. The through-hole 400a is a tapped hole into which a fixing member 401 (butterfly bolt 401) for fixing the support portion main body 410 is screwed. Each of the pair of erection sections 400 has one longitudinal end placed on a support base 3 on the carriage 2 on the first mobile unit 1 side, and the other end placed on a support base 3 on the carriage 2 on the second mobile unit 100 side.

[0061] The support body 410 is provided so as to span between the pair of bridge parts 400. In other words, it is provided so as to straddle the pair of bridge parts 400. In plan view, this support body 410 is formed long in the direction spanning the pair of bridge parts 400. In other words, this support body 410 is formed short in the direction in which adjacent mobile units 1,100 adjoin each other in plan view.

[0062] As shown in Figure 10, such a support body 410 is formed in a box shape by a top panel portion 411 and four side panel portions 412 integrally formed on the four sides of this top panel portion 411. A through-hole 411a penetrating the top panel 411 is formed in the center of the upper surface of the top panel 411, and a nut 411b is welded to the center of the lower surface of the top panel 411 in alignment with the position of the through-hole 411a. A first fixing member 44 is screwed into the nut 411b. Note that a butterfly bolt that can be manually tightened and loosened is used as the first fixing member 44 in this embodiment.

[0063] In addition, the support body 410 has a mounting plate 413 that protrudes outward from the lower end of the side plate portions 412 at both ends of the longitudinal direction of the four side plate portions 412, and an auxiliary plate 414 that protrudes outward from the lower end of the side plate portions 412 at both ends of the transverse direction of the four side plate portions 412.

[0064] The entire mounting plate 413 is placed on the upper surface of the erection section 400, and a long hole 413a is formed in the position facing the through hole 400a of the erection section 400, the long hole 413a being set long in the direction in which adjacent mobile units 1,100 are adjacent to each other. The mounting plates 413 at both ends are formed with long holes 413a, and these long holes 413a extend from the center of the mounting plate 413 in the direction in which one of the adjacent mobile units 1,100 is located, and are formed with the same length, as shown in Figure 10(d). This allows the position of the support body 410 to be adjusted between the adjacent mobile units 1,100 while it is placed on a pair of installation parts 400 that are installed to bridge the adjacent mobile units 1,100. That is, the fixing material 401 is passed through the elongated hole 413a of the mounting plate 413 and the through-hole 400a of the installation part 400, and before the support body 410 and the installation part 400 are completely fixed together, the position of the support body 410 is adjusted, and once the position is determined, the fixing material 401 is tightly fastened.

[0065] The auxiliary plate 414 is in a state where both longitudinal ends thereof are placed on the pair of bridge parts 400. This makes it easier to prevent the support part main body 410 from shifting or tilting in the short side direction.

[0066] The floor surface portion 42 has a base portion 420 that is placed on a support portion 41 that is bridged between adjacent mobile units 1,100 and fixed to the support portion 41 by a first fixing member 44, a floor finishing portion 430 that is removably fixed to the upper surface of the base portion 420 and forms the floor surface of the passage space 20, and a second fixing member 440 for fixing the floor finishing portion 430 to the base portion 420.

[0067] The base portion 420 is provided so as to span a pair of support portions 41 that are arranged at an interval in the width direction (north-south direction) of the passage space 20. 11, such base part 420 has a frame body formed by assembling a pair of vertical frame members 421 and a pair of horizontal frame members 422 into a rectangular shape, with an upper surface member 423 attached to the upper surface of this frame body and a lower surface member 424 attached to the lower surface, resulting in a hollow structure. Furthermore, the hollow interior is filled with heat insulating material 425 such as glass wool or rock wool.

[0068] An elongated access hole 423c is formed in the upper surface member 423, through which the heat insulating material 425 can be inserted and removed. The access hole 423c has an opening width that allows a person to insert their hand and perform the work of tightening and loosening the first fixing member 44. In other words, when performing the work of tightening and loosening the first fixing member 44, the person first removes the heat insulating material 425 from the access hole 423c, and then inserts their hand through the access hole 423c. Furthermore, through holes 423a into which second fixing members 440 for fixing the floor finishing portion 430 are inserted are formed at both longitudinal ends of the upper surface member 423, and nuts 423b are fixed to the lower surface of the upper surface member 423 in accordance with the positions of the through holes 423a. That is, the second fixing members 440 are passed through the through holes 423a of the upper surface member 423 and screwed into the nuts 423b.

[0069] At both ends of the lower surface member 424 in the length direction, through holes 424a are formed into which first fixing members 44 for fixing the base portion 420 to the pair of support portions 41 are inserted. Furthermore, recesses 424b are formed on both longitudinal ends of the lower surface material 424 closer to the tip than the through holes 424a. These recesses 424b are for storing the waterproof fasteners 313, 323 located at the lower end of the waterproof sheet part 30, and are formed in a state where they are open downward and on the end face side. If the inner sheet portion 31 and the outer sheet portion 32 of the waterproof sheet portion 30 were left hanging as shown by the dashed lines in Figure 8, not only would it look bad, but a gap would also be formed between the inner sheet portion 31 and the floor portion 40, and the second insulating material 35 filled between the inner sheet portion 31 and the outer sheet portion 32 would not be able to provide support. Therefore, the lower ends of the inner sheet portion 31 and the outer sheet portion 32 are sandwiched between the support portion 41 and the floor portion 42 to prevent a gap from being formed between the inner sheet portion 31 and the floor portion 40. Furthermore, the lower end of the gap between the inner sheet portion 31 and the outer sheet portion 32 can be closed, which prevents the second insulating material 35 from falling and improves the appearance. Furthermore, because the sliders and stoppers of the inner waterproof zipper 313 and outer waterproof zipper 323 are present at the lower ends of the inner sheet portion 31 and the outer sheet portion 32, it is difficult to sandwich them as they are between the support portion 41 and the floor portion 42, but because recesses 424b are formed at both longitudinal ends of the undersurface material 424 of the base portion 420, it is possible to store the sliders and stoppers of the inner waterproof zipper 313 and outer waterproof zipper 323 in these recesses 424b. This improves the fit when the lower ends of the inner sheet portion 31 and outer sheet portion 32 are sandwiched between the support portion 41 and the floor portion 42.

[0070] The floor finishing portion 430 is a flooring material that is exposed to the passage space 20 and forms the floor surface, and is placed on the upper surface of the base portion 420 and fixed to the base portion 420. Countersunk portions 431 are formed at both longitudinal ends of such floor finishing portion 430, and a through hole 432 into which a second fixing member 440 is inserted is formed in the center of these countersunk portions 431. Because a butterfly bolt is used for the second fixing member 440, the head of the second fixing member 440 inserted into the through hole 432 fits into the countersunk portion 431. A cap can be fitted into the countersunk portion 431 to hide the head of the second fixing member 440.

[0071] The left and right corners at both ends of the floor finishing portion 430 in the longitudinal direction are cut out to form L-shaped notched corners 433 in a plan view. In other words, the four corners of the floor finishing portion 430 are cut out to form L-shaped notches in a plan view, and the floor finishing portion 430 has four notched corners 433. Such a cutout corner portion 433 is formed to absorb the protrusion of the sash frame for building materials that forms the first communication opening 14a on the first mobile unit 1 side and the second communication opening 113a on the second mobile unit 100 side, as shown in Figure 7, etc.

[0072] Next, the sealing material 43 is, for example, an EPT sealer sheet, and as shown in FIGS. 9 and 11, is sized to protrude in all directions (east, west, north, south) from the base portion 420. Such sealing material 43 is a sheet sandwiched between the support portion 41 and the floor portion 42, and a through hole 43a is formed at the position where the first fixing material 44 passes from the floor portion 42 toward the support portion 41. 9, the sealing material 43 sandwiched between the support portion 41 and the floor portion 42 is provided so as to bridge between adjacent mobile units 1,100. To explain in more detail, flashing materials 14c, 113c are attached below the sash frames for fittings that form the first communication opening 14a and the second communication opening 113a of adjacent mobile units 1,100. The sealing material 43 is provided so as to bridge between these flashing materials 14c, 113c.

[0073] 9, a first insulating material 45 is filled in the gap on the upper surface of the sealing material 43, and between the floor surface portion 42 and the mobile unit 1,100 adjacent to the floor surface portion 42, to improve the thermal insulation of the floor portion 40. The first insulating material 45 may be filled in the gap between both longitudinal ends of the floor portion 40 (base portion 420 and floor finish portion 430) and the inner sheet portion 31, as shown in FIG.

[0074] The sealing material 43, together with the lower ends of the inner sheet portion 31 and the outer sheet portion 32, is sandwiched between the support portion 41 and the floor portion 42. At this time, the sealing material 43 is located higher than the inner sheet portion 31 and the outer sheet portion 32. In other words, the sealing material 43 is layered on the lower ends of the inner sheet portion 31 and the outer sheet portion 32, the floor portion 42 is placed on top of the sealing material 43, and the floor portion 42 is fixed to the support portion 41 by the first fixing material 44.

[0075] [About connecting the mobile unit] Next, a case where the first mobile unit 1 and the second mobile unit 100 are connected by a connecting and surrounding means will be described.

[0076] First, the base plate portion 23 and the sheet metal cover 24 are attached to the third side wall 14 of the first mobile unit 1 and the second side wall 113 of the second mobile unit 100. The attachment of the base plate portion 23 and the sheet metal cover 24 may be performed on-site, but is basically performed during the manufacturing stage of the first mobile unit 1 and the second mobile unit 100.

[0077] Next, the angle members of the first retaining portion 21 and the second retaining portion 22 are fixed to the base plate portion 23. Fixing of the angle members to the first inner retaining portion 21A, the first outer retaining portion 21B, the second inner retaining portion 22A, and the second outer retaining portion 22B may also be performed on-site, or may be performed during the manufacturing stage of the first mobile unit 1 and the second mobile unit 100. In particular, of the first outer retaining portion 21B and the second outer retaining portion 22B, the second angle member that is inserted into the slit 23a of the base plate portion 23 is preferably fixed during the manufacturing stage.

[0078] In this embodiment, the attachment of the base plate portion 23 and the sheet metal cover 24 and the fixing of the angle members of the first holding portion 21 and the second holding portion 22 are performed during the manufacturing stage of the first mobile unit 1 and the second mobile unit 100. In this case, the first mobile unit 1 and the second mobile unit 100 are then placed on a dolly 2 and towed and transported by an automobile (not shown), and are set in a suitable location while still on the dolly 2. At this time, the first mobile unit 1 and the second mobile unit 100 are positioned adjacent to each other so that the first communication opening 14a and the second communication opening 113a face each other.

[0079] Next, the first outer sheet piece 321 on the first mobile unit 1 side of the outer sheet portion 32 is sandwiched between both angle members of the first outer holding portion 21B of the first holding portion 21 and fixed by the fixing member 25, so that the first outer sheet piece 321 is held on the first mobile unit 1 side. In addition, the second outer sheet piece 322 on the second mobile unit 100 side of the outer sheet portion 32 is sandwiched between both angle members of the second outer holding portion 22B of the second holding portion 22 and fixed by the fixing member 25, so that the second outer sheet piece 322 is held on the second mobile unit 100 side.

[0080] Next, the first inner sheet piece 311 on the first mobile unit 1 side of the inner sheet portion 31 is sandwiched between both angle members of the first inner holding portion 21A of the first holding portion 21 and fixed by the fixing member 25, so that the first inner sheet piece 311 is held on the first mobile unit 1 side. In addition, the second inner sheet piece 312 on the second mobile unit 100 side of the inner sheet portion 31 is sandwiched between both angle members of the second inner holding portion 22A of the second holding portion 22 and fixed by the fixing member 25, so that the second inner sheet piece 312 is held on the second mobile unit 100 side. The work of holding the inner sheet portion 31 and the outer sheet portion 32 can be performed from the aisle space 20 side.

[0081] Next, the first outer sheet piece 321 on the first mobile unit 1 side and the second outer sheet piece 322 on the second mobile unit 100 side are connected by an outer waterproof fastener 323. The first outer sheet piece 321 and the second outer sheet piece 322 connected by the outer waterproof fastener 323 can be handled as a single outer sheet part 32.

[0082] Next, the first inner sheet piece 311 on the first mobile unit 1 side and the second inner sheet piece 312 on the second mobile unit 100 side are connected by an inner waterproof zipper 313. The first inner sheet piece 311 and the second inner sheet piece 312 connected by the inner waterproof zipper 313 can be handled as a single inner sheet portion 31. In addition, at the same time as connecting the first inner sheet piece 311 and the second inner sheet piece 312 with the inner waterproof fastener 313, the second insulating material 35 is filled between the inner sheet portion 31 and the outer sheet portion 32.

[0083] Next, the pair of support parts 41 in the floor part 40 are respectively installed to span between the support bases 3 of adjacent mobile units 1,100. That is, the pair of installation parts 400 in each support part 41 are respectively installed to span between the support bases 3. The pair of installation parts 400 and the support part main body 410 are in a state before being completely fixed by the fixing members 401, and are in a state where their position can be adjusted. The positioning of the support part main body 410 may be performed when the pair of installation parts 400 are respectively installed to span between the support bases 3, or may be performed after the position of the base part 420 or the floor finishing part 430 has been determined to some extent. In this embodiment, the positioning is performed when the pair of installation parts 400 are respectively installed to span between the support bases 3.

[0084] Next, the lower ends of the inner sheet portion 31 and the outer sheet portion 32 (i.e., both longitudinal ends of the waterproof sheet portion 30) are folded onto the upper surfaces of the pair of support portions 41, a sealing material 43 is laid on top of them, and then the base portion 420 of the floor portion 42 is placed on top. The base portion 420 is then spanned across the pair of support portions 41 and fixed to each of the pair of support portions 41 with the first fixing members 44. That is, the first fixing members 44 are passed through the through holes 424a in the lower surface members 424 of each base portion 420, the through holes 43a in the sealing material 43, and the through holes 411a in the top panel portion 411 of the support portion main body 410 of the support portion 41, and then screwed into the nuts 411b on the back side of the top panel portion 411. At this time, the first fixing members 44 are arranged from top to bottom, thereby fixing the base portion 420 to the support portions 41. The heat insulating material 425 of the base part 420 is taken in and out as needed, and after the base part 420 is fixed to the support part 41, the heat insulating material 425 is surely loaded.

[0085] Next, the first insulating material 45 is filled around the base portion 420. That is, the first insulating material 45 for improving the thermal insulation of the floor portion 40 is filled on the upper surface of the sealing material 43 and in the gap between the floor surface portion 42 and the mobile unit 1,100 adjacent to the floor surface portion 42. The first insulating material 45 is also filled in the gap between both longitudinal ends of the base portion 420 and the inner sheet portion 31.

[0086] Next, the floor finishing part 430 is placed on the upper surface of the base part 420, and the second fixing member 440 is passed through the through hole 432 of the floor finishing part 430 and the through hole 423a of the upper surface member 423 of the base part 420, and screwed into the nut 423b on the back side of the upper surface member 423. At this time, the second fixing member 440 is provided from top to bottom, thereby fixing the floor finishing part 430 to the base part 420.

[0087] In this manner, 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 base plate 23 and the sheet metal cover 24 and the fixing of the angle members of the first holding portion 21 and the second holding portion 22 are performed during the manufacturing stage of the first mobile unit 1 and the second mobile unit 100, but this is not limited to this. For example, the first inner sheet piece 311 and the first outer sheet piece 321 may be held in advance by the first inner holding portion 21A and the first outer holding portion 21B of the first mobile unit 1, respectively, and the second inner sheet piece 312 and the second outer sheet piece 322 may be held in advance by the second inner holding portion 22A and the second outer holding portion 22B of the second mobile unit 100, respectively, before the first mobile unit 1 and the second mobile unit 100 are transported. In this case, at the construction site, only the connection of the inner sheet portion 31 and the outer sheet portion 32 with the outer waterproof fastener 323 and the inner waterproof fastener 313, the placement of the floor portion 40, and the sandwiching of the waterproof sheet portion 30 may be performed.

[0088] According to this embodiment, the following excellent effects are achieved. In other words, the connecting and surrounding means is provided between adjacent mobile units 1,100 to connect the mobile units 1,100 to each other, and also surrounds the area between the opposing communication openings 14a, 113a to form an aisle space 20, so that adjacent mobile units 1,100 can be easily connected to each other in a state where they can move freely between the adjacent mobile units 1,100, and can also be easily separated, thereby maintaining a state in which multiple mobile units 1,100 can move at any time and as desired. Furthermore, the connecting and enclosing means has a waterproof sheet portion 30 that covers at least the upper edge portion 20a, one side edge portion 20b, and the other side edge portion 20c of the passage space 20, so that the waterproof sheet portion 30 can prevent rainwater from entering the passage space 20 at a position above the floor portion 40. Furthermore, the connecting and enclosing means is not fixed to adjacent mobile units 1,100 but is bridged between the adjacent mobile units 1,100 and is positioned at the lower edge of the aisle space 20, and has a floor section 40 that holds the lower ends of both side edges of the waterproof sheet section 30.This floor section 40 allows adjacent mobile units 1,100 to be easily connected along the lower edge section 20d of the aisle space 20, making it usable for walking, while the waterproof sheet section 30 and the floor section 40 surround the aisle space 20 without any gaps, improving waterproofing and ensuring weatherproofing at the connection points between adjacent mobile units 1,100. Moreover, the floor section 40 comprises support sections 41 arranged to span between adjacent mobile units 1,100, floor surface sections 42 that are detachably fixed to the upper surfaces of the support sections 41 and form the floor surface of the passage space 20, and first fixing members 44 for fixing the floor surface section 42 to the support sections 41, and the first fixing members 44 are provided from top to bottom from the floor surface section 42 toward the support sections 41, thereby fixing the floor surface section 42 to the support sections 41, so that the work of fixing the floor surface section 42 to the support sections 41 can be performed from above. In other words, since the work of fixing the floor surface section 42 to the support sections 41 can be performed within the passage space 20, it is possible to fix and release the floor surface section 42 to the support sections 41 more easily than, for example, when fixing the floor surface section 42 to the support sections 41, compared to when the work is performed from below. This allows adjacent mobile units 1,100 to be more easily connected to each other in a state where they can move freely between the adjacent mobile units 1,100, and also allows them to be more easily separated, so that multiple mobile units 1,100 can be maintained in a state where they can move at any time and as desired.

[0089] Furthermore, the floor surface portion 42 has a base portion 420 that is placed on the support portion 41 and fixed to the support portion 41 by first fixing members 44, a floor finishing portion 430 that is detachably fixed to the upper surface of the base portion 420 and forms the floor surface of the aisle space 20, and second fixing members 440 for fixing the floor finishing portion 430 to the base portion 420, and the second fixing members 440 are provided from top to bottom from the floor finishing portion 430 toward the base portion 420, thereby fixing the floor finishing portion 430 to the base portion 420, so that work can be done from above when fixing the floor finishing portion 430 to the base portion 420. In other words, since the work of fixing the floor finishing portion 430 to the base portion 420 can be done within the aisle space 20, it is possible to fix and release the floor finishing portion 430 to the base portion 420 more easily than if, for example, work was done from below when fixing the floor finishing portion 430 to the base portion 420. This allows adjacent mobile units 1,100 to be more easily connected to each other in a state where they can move freely between the adjacent mobile units 1,100, and also allows them to be more easily separated, so that multiple mobile units 1,100 can be maintained in a state where they can move at any time and as desired.

[0090] The support section 41 has an erection section 400 that spans between adjacent mobile units 1,100, and a support section main body 410 that is mounted on and attached to the erection section 400 and has a floor section 42 fixed to its upper surface by a first fixing member 44. The support section main body 410 is slidable on the upper surface of the erection section 400 in the direction in which the erection section 400 spans between adjacent mobile units 1,100, so that the position of the support section main body 410 can be adjusted according to the distance between adjacent mobile units 1,100. This allows the position of the floor section 42 that constitutes the floor of the passage space 20 to be located in the middle part between adjacent mobile units 1,100, thereby improving the ease of walking within the passage space 20. Furthermore, since the floor portion 40 including the floor surface portion 42 holds the waterproof sheet portion 30, it is possible to prevent the waterproof sheet portion 30 from being twisted to one side of the adjacent mobile units 1,100, thereby contributing to ensuring weatherproofing at the connection points between the adjacent mobile units 1,100.

[0091] Furthermore, a sheet-like sealing material 43 is sandwiched between the support portion 41 and the floor portion 42, and the sealing material 43 is bridged between adjacent mobile units 1,100, so that the portion of the floor portion 40 that is located above the support portion 41 can be protected by the sealing material 43. This contributes to ensuring weatherproofing at the connection points between adjacent mobile units 1,100 that are located above the support portion 41.

[0092] Furthermore, the first insulating material 45 is filled in the gap on the top surface of the sealing material 43 and between the floor surface portion 42 and the mobile unit 1,100 adjacent to the floor surface portion 42, thereby improving the thermal insulation of the floor portion 40 of the passage space 20. Furthermore, since the first insulating material 45 is filled, the floor surface portion 42 is less likely to shift toward one of the adjacent mobile units 1,100, which prevents the waterproof sheet portion 30 held by the floor portion 40 from being twisted toward one of the adjacent mobile units 1,100, thereby contributing to ensuring weatherproofing at the connection points between the adjacent mobile units 1,100.

[0093] In addition, the waterproof sheet portion 30 has an inner sheet portion 31 located on the communication openings 14a, 114a side, and an outer sheet portion 32 located further outward than the inner sheet portion 31, and the inner sheet portion 31 and the outer sheet portion 32 are configured to be easily separable to the first mobile unit 1 side and the second mobile unit 100 side, respectively, so that adjacent mobile units 1,100 can be easily connected to each other in a state where they can move freely between the adjacent mobile units 1,100, and can also be easily separated, thereby maintaining a state in which multiple mobile units 1,100 can be moved at any time and as desired. Furthermore, since the second insulating material 35 is filled between the inner sheet portion 31 and the outer sheet portion 32, it is possible to improve the thermal insulation in the portion of the aisle space 20 that is located above the floor portion 40. This makes it easier to maintain a comfortable thermal environment in the internal spaces of the first mobile unit 1 and the second mobile unit 100 that are adjacent to the aisle space 20.

[0094] In recent years, there has been a demand to realize a carbon-neutral society by reducing carbon dioxide emissions to virtually zero, and to achieve the targets of the SDGs (Sustainable Development Goals).In response to this, the construction industry is also making efforts to build buildings using wood, which has low carbon dioxide emissions. The unit body of the mobile unit 1,100 in this embodiment is mostly made up of architectural wood panels, which can contribute to realizing a carbon-free society by promoting carbon neutrality and achieving the SDGs (Goals 7, 12, and 13). Furthermore, the mobile unit 1,100 of this embodiment can also be used as temporary housing in the event of a disaster, and can therefore contribute to achieving the SDGs (Goal 11).
