Description

Technical Field

[0001] The present invention relates to a connection structure of mobile units.

Background Art

[0002] Conventionally, mobile units that can be easily relocated or installed are widely known as container houses, trailer houses, camper vans, etc. In addition, mobile units are increasingly in demand in recent years, such as being permanently installed as houses, stores, or offices, being used as temporary accommodation facilities, or being used as temporary housing during natural disasters. On the other hand, since such mobile units are towed and transported by automobiles, they need to be sized to fit within legal regulations (such as the Road Transport Vehicle Law, etc.). However, there is a problem that the internal space is narrow accordingly. Therefore, for example, as disclosed in Patent Document 1, there are cases where a plurality of mobile units are connected to enable passage between them for the purpose of expanding the internal space.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, depending on the usage form, mobile units may not be regarded as buildings under the Building Standards Law. In such cases, without using dedicated tools, etc., a plurality of mobile units should be easily connected to each other and easily divided (separated), so that a state where a plurality of mobile units can move at any time and arbitrarily can be maintained. Furthermore, when connecting a plurality of mobile units to each other, it is necessary to prevent the intrusion of rainwater, etc., so ensuring the rainproofing at the connection part is required. Furthermore, since the mobile units are placed in a fixed location while mounted on trolleys, the distance between trolleys carrying multiple mobile units may narrow or widen due to vibrations, for example. In particular, if the distance between trolleys widens, the floor sections provided at the connection points between multiple mobile units may become more prone to detachment.

[0005] The present invention has been made in view of the above circumstances, and its purpose is to enable multiple mobile units to be easily connected and easily separated, thereby maintaining a state in which multiple mobile units can be moved at any time and arbitrarily, and furthermore, to ensure waterproofing at the connection points between multiple mobile units, and to prevent the floor portion provided at the connection points between multiple mobile units from falling off. [Means for solving the problem]

[0006] The invention described in claim 1 is such that, as shown in Figures 1 to 13, for example, a plurality of mobile units 1,100 are placed on a trolley 2, towed and transported by an automobile, and while remaining on the trolley 2, are placed in a location where they can be fixed, and are arranged adjacent to each other with their connecting ports 14a and 113a facing each other. It is provided with a connecting and surrounding means that is installed between adjacent mobile units 1,100 to connect the mobile units 1,100 and surrounds the opposing connecting ports 14a and 113a to form a passage space 20. The aforementioned connecting and surrounding means is It has a floor section 40 that is not fixed to adjacent mobile units 1,100, but is stretched between adjacent mobile units 1,100 and positioned at the lower edge of the passage space 20, The floor portion 40 is A support section 41 is positioned and spanned between adjacent mobile units 1,100, A floor surface portion 42 is detachably fixed to the upper surface of the support portion 41 and constitutes the floor surface of the passage space 20, The device is characterized by having an anti-detachment part 50 that is attached to the support part 41 and hooks onto a part of the trolley 2 (support base 3) on which one of the adjacent mobile units 1,100 is mounted.

[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 and surrounds the opposing communication openings 14a and 113a to form a passage space 20. This allows adjacent mobile units 1,100 to be easily connected and separated, enabling them to move freely between each other, and maintaining a state in which multiple mobile units 1,100 can be moved at any time and arbitrarily. Furthermore, the connecting and surrounding means connects multiple mobile units 1,100 together and surrounds the opposing connecting openings 14a and 113a to form a passage space 20. This makes it difficult for rainwater to enter the passage space 20, contributing to ensuring waterproofing at the connection points between adjacent mobile units 1,100. Furthermore, the connecting and surrounding means has a floor portion 40 that is not fixed to adjacent mobile units 1,100 but is stretched between the adjacent mobile units 1,100 and positioned at the lower edge of the passage space 20. This floor portion 40 allows adjacent mobile units 1,100 to be easily connected along the lower edge 20d of the passage space 20, and can be used for walking. Moreover, the floor section 40 includes a support section 41 that is positioned between adjacent mobile units 1,100, a floor surface section 42 that is detachably fixed to the upper surface of the support section 41 and constitutes the floor surface of the passage space 20, and an anti-detachment section 50 that is attached to the support section 41 and hooks onto a part (support base 3) of the trolley 2 on which one of the adjacent mobile units 1,100 is mounted. Therefore, if the distance between the trolleys 2 on which multiple mobile units 1,100 are mounted widens due to vibration or the like, the displacement will only occur on the side of one of the mobile units 100. In other words, if the fall prevention part 50 were hooked onto both of the trolleys 2 on which adjacent mobile units 1,100 are mounted, when the distance between the trolleys 2 widens, it could lead to damage to the fall prevention part 50, potentially failing to prevent the floor part 40 from falling off. However, since the fall prevention part 50 is only hooked onto a part of the trolley 2 on which one of the mobile units 100 is mounted, even if the distance between the trolleys 2 widens, it will only cause a displacement on the side of one of the mobile units 100, thus preventing the floor part 40 from falling off.

[0008] The invention described in claim 2 is, for example, as shown in Figures 1 to 3 and 7 to 10, in the connecting structure of the mobile unit 1,100 described in claim 1, The trolley 2 has a support base 3 on which the mobile unit 1,100 is placed. The support base 3 is constructed in a frame-like manner using frame material. The anti-detachment part 50 is characterized by being hooked onto the inner surface of the frame material of the support base 3.

[0009] According to the invention described in claim 2, since the fall prevention part 50 is hooked onto the inner surface of the frame material of the support base 3 on the trolley 2, when the distance between the trolleys 2 widens, the floor part 40 can be made to shift position toward the mobile unit 100 to which the fall prevention part 50 is hooked. In other words, the direction in which the floor part 40 will shift position can be designed in advance, making it possible to prevent the floor part 40 from falling off.

[0010] The invention described in claim 3 is, for example, as shown in Figures 7 to 10, in the connecting structure of the mobile unit 11,100 described in claim 1, The support portion 41 in the floor portion 40 is A bridge section 400 is stretched between adjacent mobile units 1,100, It is mounted on the aforementioned erection section 400 and has a support body 410 on its upper surface to which the floor section 42 is fixed, The anti-detachment part 50 is characterized in that it is attached to one end of the erection part 400 on the side of the mobile unit 100.

[0011] According to the invention described in claim 3, the fall prevention part 50 can be attached to one end of the erection part 400 on the mobile unit 100 side, in a part where the support part body 410 is not attached, so that the fall prevention part 50 can be positioned in a location that does not affect walking in the passage space 20.

[0012] The invention described in claim 4, for example as shown in Figures 7 to 10, relates to the connecting structure of the mobile unit 1,100 described in claim 2, The aforementioned detachment prevention part 50 is A mounting plate portion 51 attached to the support portion 41 of the floor portion 40, A downward-hanging plate portion 52 is integrally formed with the mounting plate portion 51 and extends downward from the mounting plate portion 51, It is characterized by having a protruding portion 54 that extends from the hanging plate portion 52 toward the frame material of the support base 3.

[0013] According to the invention described in claim 4, the anti-falling part 50 includes a mounting plate part 51 attached to the support part 41 of the floor part 40, a hanging plate part 52 integrally formed with the mounting plate part 51 and extending downward from the mounting plate part 51, and a protruding part 54 protruding from the hanging plate part 52 toward the frame material of the support base 3. Therefore, the protruding part 54 can be arranged below the mounting plate part 51 by the hanging plate part 52. That is, since the protruding part 54 can be arranged below the location where the anti-falling part 50 is attached to the support part 41 of the floor part 40, considering the positional relationship between the support base 3 and the mobile unit 100 placed thereon, the protruding part 54 can be easily hooked on the inner surface of the frame material constituting the support base 3.

[0014] The invention described in claim 5 is, for example, as shown in FIGS. 8 and 11, in the connection structure of the mobile units 1, 100 described in claim 4, The protruding part 54 is a bolt 54 screwed into a tapped hole 52a formed in the hanging plate part 52, and the tip of the bolt 54 is hooked on the inner surface of the frame material of the support base 3.

[0015] According to the invention described in claim 5, the protruding part 54 is a bolt 54 screwed into a tapped hole 52a formed in the hanging plate part 52, and the tip of the bolt 54 is hooked on the inner surface of the frame material of the support base 3. Therefore, by screwing the protruding part 54, which is a bolt, deeper or shallower, the strength of contact with the inner surface of the frame material of the support base 3 can be adjusted.

[0016] The invention described in claim 6 is, for example, as shown in FIGS. 4 to 7, in the connection structure of the mobile units 1, 100 described in claim 1, The connecting and surrounding means further has a waterproof sheet part 30 that at least covers the upper edge part 20a, one side edge part 20b, and the other side edge part 20c of the passage space 20, and the floor part 40 holds the lower ends of both sides of the waterproof sheet part 30.

[0017] According to the invention described in claim 6, since the connecting and surrounding means has a waterproof sheet portion 30 that at least covers the upper edge portion 20a, one side edge portion 20b, and the other side edge portion 20c of the passage space 20, the waterproof sheet portion 30 can prevent rainwater from entering the passage space 20 above the floor portion 40. Furthermore, since the floor portion 40 holds the lower end portions of both side edges of the waterproof sheet portion 30, the passage space 20 can be surrounded without gaps by the waterproof sheet portion 30 and the floor portion 40 to improve waterproof performance, and it is possible to ensure the rainproof closing at the connection location between adjacent mobile units 1 and 100.

Effect of the Invention

[0018] According to the present invention, a plurality of mobile units can be easily connected and easily divided so that a state where the plurality of mobile units can move at any time and arbitrarily can be maintained. Furthermore, rainproof closing at the connection location between the plurality of mobile units can be ensured, and moreover, it is possible to prevent the floor portion provided at the connection location of the plurality of mobile units from falling off.

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

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

[0022] Furthermore, the Mobile Unit 1,100 has passed vehicle inspections and is set to a size within legal regulations (Building Standards Act, Road Transport Vehicle Act) (Limits under Article 2 of the Safety Standards: vehicle width within 2.5m, vehicle length within 12m, vehicle height within 3.8m). This allows the Mobile Unit 1,100 to be legally moved on public roads. However, it may be possible to set it to a size larger than the limit with special permission. Furthermore, the mobile unit 1,100 shall meet all the standards required for installation at the designated location.

[0023] The bogie 2, also called a chassis, comprises a support base 3 to which wheels 3a are attached, and a plurality of support legs (not shown) that are detachably provided on the support base 3. The support base 3 is formed in a frame-like (frame-like) manner by multiple frame materials, and the box-shaped unit body of the mobile unit 1,100 is placed on it and integrated with it. Furthermore, a connecting portion 3b is integrally formed at the front end of the support base 3, projecting forward and connecting to an automobile. Multiple support legs are provided at a total of six locations: the four corners of the support base 3 and two locations near the wheel 3a (the longitudinal center of the support base 3). The support legs are jack devices that allow the parts in contact with the support base 3 to be raised and lowered manually.

[0024] The mobile units 1,100 are arranged adjacent to each other in a place where they can be permanently installed. In this embodiment, the mobile units are arranged in an L-shape in plan view such that the rear end of the other mobile unit 100 (hereinafter referred to as the second mobile unit 100) abuts against the left side of the front end of one mobile unit 1 (hereinafter referred to as the first mobile unit 1). However, a small gap is formed between these mobile units 1,100. The width of this gap is set to, for example, about 100 to 300 mm. The length of the gap between the mobile units 1,100 is equal to the length in the left-right width direction of 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 height of the mobile unit 1,100. Furthermore, these mobile units 1,100 are arranged so that the communication ports 14a and 113a formed on their opposing sides face each other directly (in a parallel positional relationship, directly opposite each other).

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

[0026] [Regarding the configuration of the mobile unit] Next, we will describe the configuration of the mobile unit 1,100 in detail. In this embodiment, the mobile unit 1,100, which is a trailer house, is assumed to include a trolley 2. Below, we will describe the box-shaped unit body that is placed on the support base 3 of the trolley 2. Furthermore, in this embodiment, the mobile unit 1 located on the right side in Figure 1 will be referred to as the first mobile unit 1, and the mobile unit 100 located on the left side will be referred to as the second mobile unit 100.

[0027] As shown in Figures 4 and 5, the unit bodies of the first mobile unit 1 and the second mobile unit 100 are formed in a box shape, comprising, as an outer casing, floors 10 and 110 that are placed on and integrated with the support base 3, roofs 11 and 111, and four side walls 12 to 15 and 112 to 115 provided between the floors 10 and 110 and the roofs 11 and 111. Such unit bodies are formed in a rectangular parallelepiped shape, with one direction (front-to-back) being longer and the other direction (left-to-right) being shorter in a plan view. In the case of the first mobile unit 1 located on the L side in a plan view, it is formed with the north-south direction being longer and the east-west direction being shorter in a plan view. On the other hand, in the case of the second mobile unit 100, it is formed with the east-west direction being longer and the north-south direction being shorter in a plan view.

[0028] Floors 10 and 110 are formed to be longer in one direction (front-to-back direction) and shorter in the other direction (left-to-right direction), forming a rectangle in plan view, and constitute the entire surface of floors 10 and 110 in the space within the first mobile unit 1 and the second mobile unit 100. Furthermore, floors 10 and 110 are constructed from hollow building wood panels. A floor finishing material (e.g., flooring material) is provided on the upper surface of the floor panels, and insulation material is filled into the hollow interior.

[0029] The roof 11 of the first mobile unit 1 is a single-slope roof, with the side facing the adjacent second mobile unit 100 (west side) being higher and the opposite side (east side) being lower. The roof 111 of the second mobile unit 100 is a single-slope roof, with the north side being higher and the south side lower, 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, there are no adjacent mobile units 1,100 in the direction of the roof slope, so it is preferable that rainwater flowing on the roofs 11,111 does not flow toward the adjacent mobile units 1,100. In addition, the roofs 11,111 are constructed from hollow wooden building panels. Roofing material (for example, galvalume steel roofing®) is provided on the surface of the roof, and insulation material is filled into the hollow interior. Furthermore, ceiling material (for example, decorative ceiling panels) is attached to the underside of the roof structure. Since roofs 11 and 111 are single-slope roofs, the ceiling appears as a sloped ceiling when viewed from inside the unit. However, this is not the only option; a horizontal ceiling consisting of joists, ceiling material, etc., may also be formed below the roof structure.

[0030] The first mobile unit 1 has four 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 of the floor 10 in the longitudinal direction (the front end side / south side). The second side wall 13 is located on the other end (rear end / north side) of the floor 10 in the longitudinal direction. The third side wall 14 is provided between the other end (left end / west side) in the width direction of the first side wall 12 and the other end (left end / west side) in the width direction of the second side wall 13. The fourth side wall 15 is provided between one end in the width direction of the first side wall 12 (right end, east side) and one end in the width direction of the second side wall 13 (right end, east side). 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 (horizontal dimension). The third side wall 14 and the fourth side wall 15 form the left and right sides of the unit body and have a long width dimension (front and rear dimension). The four side walls 12-15 are constructed from hollow wooden building panels. Exterior wall materials (e.g., galvalume steel siding or other siding materials) are installed on the exterior side of the wall, while interior wall materials (e.g., gypsum board) and wall finishing materials (e.g., wallpaper) are installed on the interior side, and insulation material is filled into the hollow interior.

[0031] Of the four side walls 12-15 of the first mobile unit 1, a first connecting opening 14a, which is an opening for people to pass through, is formed at the front end (south side) of the third side wall 14 located on the second mobile unit 100 side. Furthermore, the third side wall 14 is provided with a first door 14b for opening and closing the first connecting opening 14a. The first door 14b is a single-leaf door and is an inward-opening door that opens towards the interior space of the first mobile unit 1.

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

[0033] Furthermore, the four side walls 112-115 are constructed from hollow, structurally constructed wooden panels. Exterior wall materials (e.g., galvalume steel siding or other siding materials) are installed on the exterior side of the wall, interior wall materials (e.g., gypsum board) are installed on the interior side, and wall finishing materials (e.g., wallpaper) are applied. Insulation material is filled into the hollow interior.

[0034] Furthermore, of the four side walls 112 to 115 of the second mobile unit 100, the second side wall 113 located on the side of the first mobile unit 1 has a second connecting opening 113a formed therein, which is an opening for people to pass through. Furthermore, the second side wall 113 is provided with a second door 113b for opening and closing the second connecting opening 113a. The second door 113b is a single-leaf door and is an inward-opening door that opens towards the interior space of the second mobile unit 100.

[0035] Furthermore, as described above, the fourth side wall 115 of the second mobile unit 100 has an entrance / exit 115a formed therein, which is an opening for people to pass through. This entrance / exit 115a is not directed toward the first mobile unit 1, but toward the outdoor space. Therefore, this entrance / exit 115a functions as the main entrance / exit of the second mobile unit 100. In addition, the fourth side wall 115 is provided with an entrance door 115b, which is a door for opening and closing the entrance / exit 115a. This allows access between the interior space of the second mobile unit 100 and the outdoor space through the entrance / exit 115a. Furthermore, since the main body of the second mobile unit 100 is positioned at a certain height by the trolley 2, the height of the entrance / exit 115a also becomes higher. For this reason, access equipment such as stairs or ramps will be installed on the outdoor side of the entrance / exit 115a, but will not be fixed to 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 in a place where they can be fixed, and are arranged so that the connecting openings 14a and 113a formed on the opposing side walls 14 and 113 face each other directly (in a parallel positional relationship, facing directly in front). The first connecting opening 14a is formed on the front end side of the third side wall 14 that constitutes the left side of the first mobile unit 1, and the second connecting opening 113a is formed on the second side wall 113 that constitutes the rear end side of the second mobile unit 100. Therefore, when the first mobile unit 1 and the second mobile unit 100 are placed side by side so that these connecting openings 14a and 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 the linking and surrounding means] Next, a connecting and surrounding means for linking adjacent mobile units 1,100 together and forming a passage space 20 will be described.

[0038] As shown in Figures 3 to 13, the connecting and surrounding means is provided between adjacent mobile units 1,100 to connect them, and also surrounds the first connecting port 14a on the side of the opposing first mobile unit 1 and the second connecting port 113a on the side of the second mobile unit 100 to form a passage space 20. In other words, the space surrounded by the connecting and surrounding means serves as a passage space 20 for moving 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, the other side edge 20c, and a lower edge 20d, which are defined by the connecting and surrounding means. The upper edge portion 20a refers to the part located above the first connecting port 14a and the second connecting port 114a, and is formed in a mountain shape. One side edge 20b refers to the straight portion located between the southern end of the upper edge 20a and the southern end of the lower edge 20d. The other side edge portion 20c refers to the straight portion located between the northern end of the upper edge portion 20a and the northern end of the lower edge portion 20d. The lower edge portion 20d refers to the straight portion located between the lower end of one side edge portion 20b and the lower end of the other side edge portion 20c.

[0040] The connecting and enclosing means defining such passage space 20 comprises a waterproof sheet portion 30 and a floor portion 40, and further comprises a first holding portion 21 and a second holding 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 side of the connecting openings 14a and 113a, 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 and 22A located on the inside (first inner retaining portion 21A and second inner retaining portion 22A), and retaining portions 21B and 22B located on the outside (first outer retaining portion 21B and second outer retaining portion 22B), respectively.

[0041] The inner sheet portion 31 of the waterproof sheet portion 30 includes 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 fastener 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 includes 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 and 321 (first inner sheet piece 311 and first outer sheet piece 321) on the first mobile unit 1 side, a waterproof second tape portion welded to the sheet pieces 312 and 322 (second inner sheet piece 312 and second outer sheet piece 322) on the second mobile unit 100 side, a first element portion provided at the edge of the first tape portion and equipped with a toothed head, a second element portion provided at the edge of the second tape portion and equipped with a toothed head, and a slider portion (not shown) for interlocking or disengaging 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 interlocked and connected to each other. The slider section 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. Furthermore, the slider section is positioned on the aisle space 20 side, allowing for the connection and disconnection of the sheet pieces 311 and 321 on the first mobile unit 1 side and the sheet pieces 312 and 322 on the second mobile unit 100 side from the aisle space 20 side.

[0044] Furthermore, the sheet pieces 311 and 321 on the first mobile unit 1 side (first inner sheet piece 311, first outer sheet piece 321) are provided with a strip-shaped watertight material 33 along the front and back of the edge (base end) on the side held by the first holding part 21 (first inner holding part 21A, first outer holding part 21B), and a plurality of eyelets 34 that form through holes into which the fixing member 25 (bolt) is inserted. The watertight material 33 is, for example, EPT sealer. Multiple eyelets 34 are provided so as to frame the through-holes that penetrate the sheet pieces 311, 321 on the first mobile unit 1 side and the watertight material 33 on the front and back sides. 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 and 322 (second inner sheet piece 312 and second outer sheet piece 322) on the second mobile unit 100 side also include a strip-shaped watertight material 33 provided along the front and back of the edge on the side held by the second holding part 22 (second inner holding part 22A and second outer holding part 22B), and a plurality of eyelets 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 comprises the first inner holding portion 21A, the first outer holding portion 21B, the base plate portion 23, the sheet metal cover 24, and the 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 edge (upper edge and both side edges) of the first communication 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 retaining portion 21A and the first outer retaining portion 21B are fixed to the base plate portion 23 with screws or the like via this sheet metal cover 242.

[0048] The first inner holding 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 the 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 these angle members that forms the L-shape is a fixing piece that is fixed to the base plate portion 23, and the other side that forms the L-shape is a retaining piece for holding the first inner sheet piece 311. The fixing piece has through holes formed at predetermined intervals through which fixing materials such as screws for fixing the angle members to the base plate portion 23 are passed. The retaining piece also has through holes formed that match the positions of multiple eyelet portions 34 (through holes) on the first inner sheet piece 311, allowing the fixing member 25 to pass through. In other words, the base end portion of the first inner sheet piece 311 (the edge on the side with the watertight material 33 and eyelet portions 34) is sandwiched between the retaining pieces of the pair of angle members and can be fixed with the fixing member 25.

[0049] The pair of angle members are divided into multiple parts so that the fixing process can be divided into several steps. In other words, as shown in Figure 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 are formed in a straight line. The angle member a that defines the shape of this passage space 20 has a mountain-shaped part at the apex, a bent part that constitutes the bent portion between the upper edge 20a and the one side edge 20b and the other side edge 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 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 to which the tip of the bolt shaft is screwed, and washers provided between the bolt and the nut and the pair of angle members, respectively.

[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 the base plate portion 23 attached to the third side wall 14 of the first mobile unit 1. The first outer retaining portion 21B comprises a first angle member attached to the surface of the base plate portion 23 and a second angle member attached by being inserted into a slit 23a formed at the outer end of the base plate portion 23. One side of these angle members forming an L shape is a fixing piece fixed to the base plate portion 23, and the other side forming the L shape is a retaining 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 for fixing the angle member to the base plate portion 23 can be passed. The retaining piece also has through holes formed that match the positions of multiple eyelet portions 34 (through holes) on 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 with the watertight material 33 and eyelet portions 34) can be sandwiched between the retaining pieces of these angle members and fixed with the fixing member 25.

[0052] These angle members, like the pair of angle members in the first inner holding section 21A, are also made into multiple parts so that the fixing process can be divided into several steps. Furthermore, the fixing member 25 used to secure the first outer sheet piece 321 is also equipped with a bolt, nut, and 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 comprises 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 edge (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. These base plate portion 23 and sheet metal cover 24 on the second mobile unit 100 side are provided in a symmetrical manner to the base plate portion 23 and sheet metal cover 24 on the first mobile unit 1 side.

[0055] The second inner holding 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 the base plate portion 23 attached to the second side wall 113 of the second mobile unit 100. This second inner retaining portion 22A has a symmetrical configuration to the first inner retaining portion 21A provided on the first mobile unit 1 side. Specifically, it has a pair of angle members, which are metal fittings with an L-shaped cross-section, and the second inner sheet piece 312 can be sandwiched between the retaining 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 the base plate portion 23 attached to the second side wall 113 of the second mobile unit 100. This second outer retaining portion 22B has a symmetrical configuration to the first outer retaining portion 21B provided on the first mobile unit 1 side. Specifically, 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 the second outer sheet piece 322 can be sandwiched between the retaining 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 held by the first retaining portion 21 (first inner retaining portion 21A, first outer retaining portion 21B) at the edge on the first mobile unit 1 side, and by the second retaining portion 22 (second inner retaining portion 22A, second outer retaining portion 22B) at the edge on the second mobile unit 100 side, thereby being provided between adjacent mobile units 1,100. Furthermore, an insulating material 35 (second insulating material), such as glass wool, is filled between the inner sheet portion 31 and the outer sheet portion 32. Furthermore, the area covered by the waterproof sheet portion 30 in 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 area in which the above-mentioned insulation material 35 is filled is also the area of ​​the upper edge 20a, one side edge 20b, and the other side edge 20c of the passage space 20. The lower edge 20d of the passage space 20 is covered by the floor 40.

[0058] The floor section 40 is not fixed to adjacent mobile units 1,100, but is stretched between the adjacent mobile units 1,100 and positioned at the lower edge 20d of the passage space 20. As shown in Figures 7 to 13, such a floor section 40 includes a support section 41 stretched between adjacent mobile units 1,100, a floor surface section 42 detachably fixed to the upper surface of the support section 41, a sealing material 43 sandwiched between the support section 41 and the floor surface section 42, a first fixing member 44 for fixing the floor surface section 42 to the support section 41, and an anti-detachment part 50 attached to the support section 41 and hooked onto a part of the trolley 2 on which at least one of the adjacent mobile units 1,100 (1) is placed.

[0059] In this embodiment, two (a pair) support parts 41 are used, and these two support parts 41 are arranged in the gap between the mobile units 1,100, spaced apart in the width direction (north-south direction) of the passage space 20. Such a support section 41 includes a pair of bridge sections 400 that are spanned between adjacent mobile units 1,100, and a support section body 410 that is provided across these bridge sections 400 and is formed in a box shape.

[0060] The erection section 400 is a rectangular metal plate, and a through-hole 400a is formed near the center in the width direction (east-west direction) that penetrates the erection section 400. The through-hole 400a is a tapped hole into which a fixing material 401 (wing bolt 401) for fixing the support section body 410 is screwed. Each of the pair of erection sections 400 has one longitudinal end resting on a support base 3 on the trolley 2 on the first mobile unit 1 side, and the other end resting on a support base 3 on the trolley 2 on the second mobile unit 100 side.

[0061] The support body 410 is installed by being spanned between a pair of erection sections 400. In other words, it is installed straddling the pair of erection sections 400. In a plan view, the support body 410 is formed to be long in the direction that spans the pair of erection sections 400. In other words, in a plan view, the support body 410 is formed to be short in the direction that adjacent mobile units 1,100 are adjacent to each other.

[0062] As shown in Figure 10, the support body 410 is formed in a rectangular tube shape and comprises a bottom plate portion, a top plate portion 411, and a side plate portion 412 integrally formed between the side edges of the bottom plate portion and the top plate portion. A through-hole 411a is formed in the center of the upper surface of the top plate portion 411, and a nut 411b is welded to the center of the lower surface of the top plate portion 411, aligned with the position of the through-hole 411a. A first fixing member 44 is screwed into the nut 411b. In this embodiment, a wing bolt is used as the first fixing member 44, which can be tightened and loosened by hand.

[0063] Furthermore, the support body 410 has mounting plates 413 that protrude outward from the lower ends of both longitudinal ends of the bottom plate. The mounting plates 413 are integrally formed with the bottom plate.

[0064] The mounting plate 413 is designed so that its entirety rests on the upper surface of the erection section 400. Opposite the through-hole 400a of the erection section 400, an elongated hole 413a is formed, which is set to be longer in the direction of adjacent mobile units 1,100. Elongated holes 413a are formed on both ends of the mounting plate 413, and as shown in Figure 10(d), these elongated holes 413a extend from the center of the mounting plate 413 in a direction that one of the adjacent mobile units 1,100 is located in, and are formed to be the same length. This allows the support body 410 to be positioned on a pair of support sections 400 that are spanned between adjacent mobile units 1,100, while the support body 410 is resting on these sections. In other words, the fixing material 401 is passed through the elongated hole 413a of the mounting plate 413 and the through-hole 400a of the support section 400, and the position of the support body 410 is adjusted before the support body 410 and the support section 400 are completely fixed together. Once the position is determined, the fixing material 401 is tightened securely.

[0065] As described above, the fall prevention part 50 is hooked onto a part of the trolley 2 on which at least one of the adjacent mobile units 1,100 (1) is mounted, and in this embodiment, it is hooked onto a part of the support base 3 on the trolley 2 on which the second mobile unit 100 is mounted. To explain in more detail, as shown in Figure 9, the fall prevention part 50 is attached to the other end in the longitudinal direction of the splice part 400, which is provided as a bridge between the support base 3 on the trolley 2 of the first mobile unit 1 and the support base 3 on the trolley 2 of the second mobile unit 100, among the support parts 41.

[0066] As shown in Figures 9 and 11, the fall prevention part 50 comprises a metal angle material consisting of a mounting plate portion 51 and a hanging plate portion 52, and a protruding member 54 that extends from the hanging plate portion 52 of the angle material toward the support base 3 and hooks onto it.

[0067] The mounting plate portion 51 of the angle material is the part that is attached to the other end in the longitudinal direction of the erection portion 400, and a pair of through holes 51a through which fixing members 53 (bolts 53) are inserted are formed to penetrate the mounting plate portion 51. Furthermore, a pair of through holes corresponding to these two through holes 51a are formed through the other end of the erection section 400 in the longitudinal direction (see Figure 9). The pair of through holes formed at the other end of the erection section 400 in the longitudinal direction are tapped holes into which the fixing members 53 (bolts 53) are screwed. The longitudinal dimension of the mounting plate portion 51 is set to be approximately equal to the transverse dimension of the erection portion 400, but it is not limited to this, and may be longer or shorter than the transverse dimension of the erection portion 400.

[0068] The hanging plate portion 52 of the angle material extends downward from the erection portion 400. As described above, the erection portion 400 is placed on the support base 3 of the trolley 2 of the second mobile unit 100, so the hanging plate portion 52 extends downward from the erection portion 400 and hangs down, thus extending below the upper surface of the support base 3. As described above, the support base 3 is formed in a frame shape, so the hanging plate portion 52 is positioned opposite the inner surface of the frame material constituting the support base 3. Furthermore, the longitudinal dimension of the hanging plate portion 52 is set to be equal to the longitudinal dimension of the mounting plate portion 51.

[0069] The protruding member 54 extends from the hanging plate portion 52 toward the inner surface of the frame material constituting the support base 3 and hooks onto it, and in this embodiment, a wing bolt 54 is used. Therefore, the hanging plate portion 52 has through holes (tapped holes) into which the wing bolt, which is the protruding member 54, is screwed. In this embodiment, a pair of protruding members 54 are hooked onto the inner surface of the frame material of the support base 3. Here, the state in which the protruding member 54 is hooked onto the inner surface of the frame material constituting the support base 3 refers to the state in which the tip of the protruding member 54 is in contact with the inner surface of the frame material. Since the protruding member 54 is a wing bolt 54, the strength of the contact with the inner surface of the frame material can be adjusted by screwing it in deeply or shallowly.

[0070] In this embodiment, two support sections 41 are used, and a pair of erection sections 400 are used for each support section 41. Therefore, four fall prevention sections 50 are used in this embodiment, which are provided at the other end in the longitudinal direction of each erection section 400. Since there is a pair of protruding members 54, eight spikes are hooked onto the inner surface of the frame material constituting the support base 3. As a result, even if the distance between adjacent mobile units 1,100 widens due to vibration or the like, the support section 41 itself is less likely to shift position relative to the second mobile unit 100. This makes it possible to prevent the floor section 40 from falling off.

[0071] The floor portion 42 includes a base portion 420 that rests on a support portion 41 spanning between adjacent mobile units 1,100 and is fixed to the support portion 41 by a first fixing member 44, a floor finishing portion 430 that is detachably fixed to the upper surface of the base portion 420 and constitutes 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.

[0072] The base section 420 is provided by being spanned across a pair of support sections 41 that are spaced apart in the width direction (north-south direction) of the passage space 20. As shown in Figure 12, the base portion 420 is constructed by assembling a pair of vertical frame members 421 and a pair of horizontal frame members 422 in a rectangular shape to form a frame. An upper surface material 423 is attached to the upper surface of this frame, and a lower surface material 424 is attached to the lower surface, resulting in a hollow internal structure. Furthermore, insulation material 425 such as glass wool or rock wool is packed into the hollow internal portion.

[0073] The top surface material 423 has an elongated work hole 423c formed therein, through which the insulation material 425 can be inserted and removed. The work hole 423c is also set to an opening width that allows a person to reach in and tighten or loosen the first fixing member 44. In other words, when tightening or loosening the first fixing member 44, the insulation material 425 is removed from the work hole 423c before a person reaches in and performs the work. Furthermore, through holes 423a are formed at both ends in the longitudinal direction of the top surface material 423, into which second fixing members 440 for fixing the floor finishing portion 430 are inserted, and nuts 423b are fixed to the lower surface of the top surface material 423 in accordance with the position of the through holes 423a. That is, the second fixing members 440 are passed through the through holes 423a of the top surface material 423 and screwed into the nuts 423b.

[0074] Through holes 424a are formed at both ends in the longitudinal direction of the bottom material 424, into which first fixing members 44 for fixing the base portion 420 to a pair of support portions 41 are inserted. Furthermore, recesses 424b are formed at both ends of the bottom material 424 in the longitudinal direction, on the end side of the through hole 424a. These recesses 424b are for housing the waterproof fasteners 313 and 323 located at the lower end of the waterproof sheet portion 30, and are formed to be open downwards and to the end face. In the waterproof sheet section 30, if the inner sheet section 31 and outer sheet section 32 are left hanging as shown by the dashed lines in Figure 8, it will not only look bad, but a gap will be formed between the inner sheet section 31 and the floor section 40, and the second insulation material 35 that fills the space between the inner sheet section 31 and the outer sheet section 32 will not be properly supported. Therefore, the lower ends of the inner sheet section 31 and the outer sheet section 32 are sandwiched between the support section 41 and the floor surface section 42 to prevent a gap from forming between the inner sheet section 31 and the floor section 40. Furthermore, the lower end of the gap between the inner sheet section 31 and the outer sheet section 32 can also be closed, preventing the second insulation material 35 from falling and improving the appearance. Furthermore, since the sliders and stoppers of the inner waterproof fastener 313 and outer waterproof fastener 323 are located at the lower ends of the inner sheet portion 31 and the outer sheet portion 32, it is difficult to simply sandwich them between the support portion 41 and the floor portion 42. However, since recesses 424b are formed at both ends in the longitudinal direction of the lower surface material 424 of the base portion 420, the sliders and stoppers of the inner waterproof fastener 313 and outer waterproof fastener 323 can be housed in these recesses 424b. This improves the fit when sandwiching the lower ends of the inner sheet portion 31 and outer sheet portion 32 between the support portion 41 and the floor portion 42.

[0075] 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. Counterbore sections 431 are formed at both ends in the longitudinal direction of the floor finish section 430, and through holes 432 into which second fixing members 440 are inserted are formed in the center of these counterbore sections 431. Since wing bolts are used for the second fixing members 440, the heads of the second fixing members 440 inserted into the through holes 432 are fitted into the counterbore sections 431. Caps can be fitted over the counterbore sections 431 to conceal the heads of the second fixing members 440.

[0076] The left and right corners at both ends in the longitudinal direction of the floor finish portion 430 are notched corner portions 433 formed by cutting out an L-shape in a plan view. In other words, the four corners of the floor finish portion 430 are notched in an L-shape in a plan view, and the floor finish portion 430 has four notched corner portions 433. As shown in Figure 7, etc., these notched corners 433 are formed to absorb the protrusions of the window frame that form the first connecting opening 14a on the first mobile unit 1 side and the second connecting opening 113a on the second mobile unit 100 side.

[0077] Next, the sealing material 43 is, for example, an EPT sealer sheet, and as shown in Figures 9 and 12, it is sized to extend in all directions (east, west, north, and south) relative to the substrate 420. Such a sealing material 43 is a sheet sandwiched between the support portion 41 and the floor portion 42, and through holes 43a are formed at the positions through which the first fixing member 44 passes from the floor portion 42 toward the support portion 41. The sealing material 43, sandwiched between the support portion 41 and the floor portion 42, is installed by being stretched between adjacent mobile units 1,100, as shown in Figure 9. More specifically, flashing materials 14c and 113c are attached below the sash frames for building fixtures that constitute the first and second connecting openings 14a and 113a of adjacent mobile units 1,100. The sealing material 43 is installed by being stretched between these flashing materials 14c and 113c.

[0078] Furthermore, as shown in Figure 9, a first insulation material 45 is filled in the gap between the upper surface of the sealing material 43 and the floor surface portion 42 and the mobile unit 1,100 adjacent to the floor surface portion 42, in order to improve the thermal insulation of the floor portion 40. The first insulation material 45 may also be filled in the gap between the inner sheet portion 31 and both ends in the longitudinal direction of the floor portion 40 (substrate portion 420 and floor finishing portion 430), as shown in Figure 7.

[0079] The sealing material 43 is sandwiched between the support portion 41 and the floor portion 42, along with the lower ends of the inner sheet portion 31 and the outer sheet portion 32. At this time, the sealing material 43 is located above the inner sheet portion 31 and the outer sheet portion 32. That is, the sealing material 43 is stacked on top of the lower ends of the inner sheet portion 31 and the outer sheet portion 32, the floor portion 42 is placed on top of that, and the floor portion 42 is fixed to the support portion 41 by the first fixing member 44.

[0080] [Regarding the connection process of mobile units] Next, we will describe the case in which the first mobile unit 1 and the second mobile unit 100 are connected by a connecting and surrounding means.

[0081] 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 done on-site, but basically it should be done during the manufacturing stage of the first mobile unit 1 and the second mobile unit 100.

[0082] Next, the angle members of the first retaining section 21 and the second retaining section 22 are fixed to the base plate section 23. The fixing of the angle members of the first inner retaining section 21A, the first outer retaining section 21B, the second inner retaining section 22A, and the second outer retaining section 22B may be done on-site, but it may also be done during the manufacturing stage of the first mobile unit 1 and the second mobile unit 100. In particular, it is desirable that the second angle member of the first outer retaining section 21B and the second outer retaining section 22B, which is inserted into the slit 23a of the base plate section 23, be fixed during the manufacturing stage.

[0083] 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. Subsequently, the first mobile unit 1 and the second mobile unit 100 are placed on a trolley 2 and towed and transported by an automobile (not shown), and while still on the trolley 2, they are set in a place where they can be fixed. At that time, the first mobile unit 1 and the second mobile unit 100 are placed adjacent to each other so that the first connecting port 14a and the second connecting port 113a face each other directly.

[0084] Next, the first outer sheet piece 321 on the first mobile unit 1 side of the outer sheet portion 32 is sandwiched between the two angle members of the first outer holding portion 21B of the first holding portion 21 and fixed with the fixing member 25, so that the first outer sheet piece 321 is held on the first mobile unit 1 side. Furthermore, the second outer sheet piece 322 on the second mobile unit 100 side of the outer sheet portion 32 is sandwiched between the two 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.

[0085] Next, the first inner sheet piece 311 on the first mobile unit 1 side of the inner sheet portion 31 is sandwiched between the two angle members of the first inner holding portion 21A of the first holding portion 21 and fixed with the fixing member 25, so that the first inner sheet piece 311 is held on the first mobile unit 1 side. Furthermore, the second inner sheet piece 312 on the second mobile unit 100 side of the inner sheet portion 31 is sandwiched between the two 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. Furthermore, the operation of holding the inner sheet portion 31 and the outer sheet portion 32 can be performed from the aisle space 20 side.

[0086] 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 treated as a single outer sheet section 32.

[0087] 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 fastener 313. The first inner sheet piece 311 and the second inner sheet piece 312 connected by the inner waterproof fastener 313 can be treated as a single inner sheet section 31. Furthermore, the first inner sheet piece 311 and the second inner sheet piece 312 are connected by an inner waterproof fastener 313, and at the same time, the second insulation material 35 is filled between the inner sheet portion 31 and the outer sheet portion 32.

[0088] Next, a pair of support sections 41 in the floor section 40 are installed by spanning them between the support bases 3 of adjacent mobile units 1,100. That is, a pair of erection sections 400 in each support section 41 are installed by spanning them between the support bases 3. The pair of erection sections 400 and the support section body 410 are in a state before being completely fixed by the fixing material 401, and their position can be adjusted. The positioning of the support section body 410 may be done when the pair of erection sections 400 are spanned between the support bases 3, or it may be done after the position of the base section 420 or the floor finishing section 430 has been determined to some extent. In this embodiment, the positioning is done when the pair of erection sections 400 are spanned between the support bases 3. Alternatively, the pair of erection sections 400 may be fitted with fall prevention parts 50 in advance, and when the pair of erection sections 400 are installed, the fall prevention parts 50 may also be hooked onto the frame material of the support base 3. This makes it more difficult for the support section 41 to move when working on the floor section 40, thereby improving work efficiency.

[0089] Next, the lower ends of the inner sheet portion 31 and the outer sheet portion 32 (i.e., both ends in the longitudinal direction of the waterproof sheet portion 30) are folded onto the upper surface 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 placed across the pair of support portions 41 and fixed to each of the support portions 41 by the first fixing member 44. Specifically, the first fixing member 44 is passed through the through-hole 424a in the lower surface material 424 of each base portion 420, the through-hole 43a in the sealing material 43, and the through-hole 411a in the top plate portion 411 of the support portion body 410 of the support portion 41, and screwed into the nut 411b on the back side of the top plate portion 411. At this time, the first fixing member 44 is provided from top to bottom, thereby fixing the base portion 420 to the support portion 41. Furthermore, the insulation material 425 of the base portion 420 should be removed and reinstalled as needed, and after the base portion 420 is fixed to the support portion 41, the insulation material 425 should be securely installed.

[0090] Next, the first insulation material 45 is filled around the base portion 420. Specifically, the first insulation material 45 is filled on the upper surface of the sealant material 43 and in the gap between the floor portion 42 and the mobile unit 1,100 adjacent to the floor portion 42 to improve the insulation performance of the floor portion 40. The first insulation material 45 is also filled in the gaps between both ends of the base portion 420 in the longitudinal direction and the inner sheet portion 31.

[0091] Next, the floor finishing section 430 is placed on the upper surface of the base section 420, and the second fixing member 440 is passed through the through hole 432 in the floor finishing section 430 and the through hole 423a in the top surface material 423 of the base section 420, and screwed into the nut 423b on the back side of the top surface material 423. At this time, the second fixing member 440 is installed from top to bottom, thereby fixing the floor finishing section 430 to the base section 420.

[0092] 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 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, 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 on the first mobile unit 1 side, 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 on the second mobile unit 100 side, respectively, before the first mobile unit 1 and the second mobile unit 100 are transported. In that case, at the 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.

[0093] This embodiment provides the following excellent effects. In other words, the connecting and surrounding means is provided between adjacent mobile units 1,100 to connect them, and also surrounds the opposing connecting openings 14a and 113a to form a passage space 20. This allows adjacent mobile units 1,100 to be easily connected and separated, enabling them to move freely between each other, and maintaining a state in which multiple mobile units 1,100 can be moved at any time and arbitrarily. Furthermore, since the connecting and surrounding means has a waterproof sheet portion 30 that covers at least the upper edge 20a, one side edge 20b, and the other side edge 20c of the passage space 20, the waterproof sheet portion 30 can prevent rainwater from entering the passage space 20 at a position above the floor portion 40. Furthermore, since the connecting and surrounding means is not fixed to adjacent mobile units 1,100 but is stretched between them and positioned at the lower edge of the passage space 20, and has a floor portion 40 that holds the lower ends of both sides of the waterproof sheet portion 30, the floor portion 40 allows adjacent mobile units 1,100 to be easily connected along the lower edge 20d of the passage space 20, making it usable for walking, while the waterproof sheet portion 30 and the floor portion 40 completely surround the passage space 20, improving waterproofing and ensuring proper drainage at the connection points between adjacent mobile units 1,100. Furthermore, the floor section 40 includes a support section 41 that is arranged spanning between adjacent mobile units 1,100, a floor surface section 42 that is detachably fixed to the upper surface of the support section 41 and constitutes the floor surface of the passage space 20, and a first fixing member 44 for fixing the floor surface section 42 to the support section 41. The first fixing member 44 is provided from top to bottom from the floor surface section 42 toward the support section 41, thereby fixing the floor surface section 42 to the support section 41. This allows work to be performed from above when fixing the floor surface section 42 to the support section 41. In other words, it is possible to perform the work of fixing the floor surface section 42 to the support section 41 within the passage space 20, making it easier to fix or detach the floor surface section 42 to the support section 41 compared to, for example, when working from below. This makes it possible to more easily connect adjacent mobile units 1,100 in a state where they can move freely between each other, and to more easily separate them, thereby maintaining a state in which multiple mobile units 1,100 can be moved at any time and arbitrarily.

[0094] Furthermore, the floor surface portion 42 includes a base portion 420 that rests on the support portion 41 and is fixed to the support portion 41 by a first fixing member 44, a floor finishing portion 430 that is detachably fixed to the upper surface of the base portion 420 and constitutes 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. The second fixing member 440 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. This allows work to be performed from above when fixing the floor finishing portion 430 to the base portion 420. In other words, it is possible to perform the work of fixing the floor finishing portion 430 to the base portion 420 within the passage space 20, making it easier to fix or release the floor finishing portion 430 to the base portion 420 compared to, for example, when working from below. This makes it possible to more easily connect adjacent mobile units 1,100 in a state where they can move freely between each other, and to more easily separate them, thereby maintaining a state in which multiple mobile units 1,100 can be moved at any time and arbitrarily.

[0095] Furthermore, the support section 41 includes a temporary section 400 that spans between adjacent mobile units 1,100, and a support section body 410 that is mounted on the temporary section 400 and has a floor surface section 42 fixed to its upper surface by a first fixing member 44. The support section body 410 is slidable along the upper surface of the temporary section 400 in the direction in which the temporary section 400 spans between adjacent mobile units 1,100, so the position of the support section body 410 can be adjusted according to the distance between adjacent mobile units 1,100. As a result, the position of the floor surface section 42 that constitutes the floor surface of the passage space 20 can be positioned in the middle of the 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 twisting towards one side of the adjacent mobile unit 1,100, thereby contributing to ensuring waterproofing at the connection points between adjacent mobile units 1,100.

[0096] 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 stretched 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 waterproofing at the connection points between adjacent mobile units 1,100 that are located above the support portion 41.

[0097] Furthermore, since the first insulation material 45 is filled on the upper surface of the sealing material 43 and in the gap between the floor surface 42 and the adjacent mobile unit 1,100, the thermal insulation of the floor surface 40 of the passage space 20 can be improved. In addition, because the first insulation material 45 is filled, the floor surface 42 is less likely to shift towards one of the adjacent mobile units 1,100, so it is possible to prevent the waterproof sheet portion 30 held by the floor surface 40 from twisting towards one of the adjacent mobile units 1,100, and thus contribute to ensuring waterproofing at the connection points between adjacent mobile units 1,100.

[0098] Furthermore, the waterproof sheet section 30 has an inner sheet section 31 located on the side of the connecting openings 14a and 114a, and an outer sheet section 32 located outside the inner sheet section 31. The inner sheet section 31 and the outer sheet section 32 are configured to be separable on the side of the first mobile unit 1 and the side of the second mobile unit 100, respectively. This allows adjacent mobile units 1,100 to be easily connected to each other, allowing them to move freely between each other, and also allows them to be easily separated, thus maintaining a state in which multiple mobile units 1,100 can be moved at any time and arbitrarily. Furthermore, since the second insulation material 35 is filled between the inner sheet portion 31 and the outer sheet portion 32, the insulation performance in areas located above the floor portion 40 of the passage space 20 can be improved. This makes it easier to support the comfort of the thermal environment in the internal spaces of the first mobile unit 1 and the second mobile unit 100 adjacent to the passage space 20.

[0099] Furthermore, the floor section 40 includes a support section 41 that is positioned across adjacent mobile units 1,100, a floor surface section 42 that is detachably fixed to the upper surface of the support section 41 and constitutes the floor surface of the passage space 20, and an anti-detachment section 50 that is attached to the support section 41 and hooks onto a part (support base 3) of the trolley 2 on which one of the adjacent mobile units 1,100 is mounted. Therefore, if the distance between the trolleys 2 on which multiple mobile units 1,100 are mounted widens due to vibration or the like, the displacement will only occur on the side of one of the mobile units 100. In other words, if the fall prevention part 50 were hooked onto both of the trolleys 2 on which adjacent mobile units 1,100 are mounted, when the distance between the trolleys 2 widens, it could lead to damage to the fall prevention part 50, potentially failing to prevent the floor part 40 from falling off. However, since the fall prevention part 50 is only hooked onto a part of the trolley 2 on which one of the mobile units 100 is mounted, even if the distance between the trolleys 2 widens, it will only cause a displacement on the side of one of the mobile units 100, thus preventing the floor part 40 from falling off.

[0100] Furthermore, since the fall prevention part 50 is hooked onto the inner surface of the frame material of the support base 3 on the trolley 2, when the distance between the trolleys 2 widens, the floor part 40 can be made to shift position toward the mobile unit 100 to which the fall prevention part 50 is hooked. In other words, the direction in which the floor part 40 will shift position can be designed in advance, making it possible to prevent the floor part 40 from falling off.

[0101] Furthermore, since the fall prevention part 50 can be attached to one end of the erection part 400 on the mobile unit 100 side, where the support part body 410 is not attached, the fall prevention part 50 can be positioned in a location that does not affect walking within the passage space 20.

[0102] Furthermore, the fall prevention part 50 includes a mounting plate portion 51 attached to the support portion 41 of the floor portion 40, a hanging plate portion 52 integrally formed with the mounting plate portion 51 and extending downward from the mounting plate portion 51, and a projection portion 54 that protrudes from the hanging plate portion 52 toward the frame material of the support base 3. Therefore, the hanging plate portion 52 allows the projection portion 54 to be positioned below the mounting plate portion 51. In other words, since the projection portion 54 can be positioned below the point where the fall prevention part 50 is attached to the support portion 41 of the floor portion 40, considering the positional relationship between the support base 3 and the mobile unit 100 placed on it, the projection portion 54 can be easily hooked onto the inner surface of the frame material constituting the support base 3.

[0103] Furthermore, the protruding portion 54 is a bolt 54 screwed into a tapped hole 52a formed in the hanging plate portion 52, and the tip of the bolt 54 is hooked onto the inner surface of the frame material of the support base 3. Therefore, the strength of the contact with the inner surface of the frame material of the support base 3 can be adjusted by screwing the protruding portion 54, which is a bolt, in deeper or shallower.

[0104] Furthermore, in recent years, there has been a growing demand for the realization of a decarbonized society through the promotion of carbon neutrality, which aims to achieve virtually zero carbon dioxide emissions, and for the achievement of the Sustainable Development Goals (SDGs). In the construction industry, efforts are also being made to use wood, which reduces carbon dioxide emissions, for buildings. Since the unit body of the mobile unit 1,100 in this embodiment is mostly composed of building wood panels, it can contribute to the realization of a decarbonized society through the promotion of carbon neutrality and to achieving the SDGs goals (Goals 7, 12, and 13). Furthermore, since the mobile unit 1,100 of this embodiment can also be used as temporary housing in the event of a disaster, it can contribute to achieving the SDGs (Goal 11).
