DETAILED DESCRIPTION

[0096] FIG. 1 illustrates an embodiment of a prefabricated cabin 1 for being transported to an installation site. The prefabricated cabin is a prefabricated log cabin. The prefabricated cabin 1 comprises a cabin box 2 comprising walls 3 surrounding an interior 4 of the cabin box 2; and support legs 5 below corners of the cabin box 2 configured for supporting the cabin box 2 on top of them. The support legs 5 are fixed to the cabin box 2. Each leg 5 is unattached to a supporting base. The prefabricated cabin 1 is liftable and lowerable as one unit to a desired place to stand on its support legs 5, e.g., during transportation and/or installation, such as on a supporting base of a transport platform or of a transport container or of the installation site.

[0097] FIGS. 2-8 illustrate the structure of a leg 5 and how it is preferably fixed to the cabin box 2.

[0098] Each said support leg 5 is arranged to carry part of the weight of the prefabricated cabin box 2. Each said support leg 5 comprises a first horizontal metal plate 6 placed below the cabin box 2 and supporting the cabin box 2 on top of it; and a second horizontal metal plate 7 configured for being placed against a supporting base, the second horizontal metal plate 7 being at a distance below the first horizontal metal plate 6; and one or more metal pillars 8,9 between said first and second horizontal metal plates 6,7 connecting them fixedly to each other. The one or more metal pillars 8,9 of the leg 5 are arranged to maintain the plates 6,7 at said distance from each other and to transmit loads between them.

[0099] In the preferred embodiment illustrated, each said wall 3 comprises horizontal, i.e., horizontally oriented, logs 10 piled on top of each other.

[0100] In a preferred embodiment, the vertical projection of the first metal plate 6 overlaps at least partially with the vertical projection of two adjacent walls 3 of the cabin box 2. This facilitates that loads are transmitted vertically without unnecessary torque. Preferably, the support leg 5 is completely on the inner side of the perimeter of the vertical projection of the walls 3 of the cabin box 2. Thereby, it does not extend horizontally over the perimeter of said vertical projection of the walls 3 of the cabin box 2. Thus, the leg is well hidden below the cabin box 2. This is visible in FIGS. 7 and 8.

[0101] The aforementioned support legs 5 are fixed to the cabin box below a corner of two adjacent walls of the cabin box 2, and also referred to as corner legs. Additional support legs could be provided also elsewhere than corners only, particularly in cases where the prefabricated cabin is relatively large or heavily loaded.

[0102] In the preferred embodiments, the first horizontal metal plate 6 is fixed to two adjacent walls of the cabin box 2, which adjacent walls are at an angle, in particular right angle relative to each other. The first horizontal metal plate 6 of the corner leg 5 is fixed to a first log end 10a of a first horizontal log 10 of the cabin box 2 and to a second log end 10b of a second horizontal log 10 of the cabin box 2, which logs are at a right angle relative to each other. Said first and second horizontal logs are logs 10 of adjacent walls which are at right angle relative to each other. The logs 10 and log ends 10a,10b are illustrated in FIGS. 1-3, and their projections are visible in FIGS. 7 and 8 in broken line as viewed from above. The first log end 10a of the first horizontal log 10 rests on a first upper support face portion 6a of the first horizontal metal plate 6 and the second log end 10b of the second horizontal log 10 rests on a second upper support face portion 6b of the first horizontal metal plate 6. Said upper support face portions 6a,6b are horizontal and coplanar.

[0103] In the preferred embodiment, there are two, and preferably only two as illustrated, of said metal pillars 8,9 between said first and second horizontal metal plates 6,7 connecting these fixedly to each other. The two pillars 8,9 are vertical (i.e., vertically oriented) metal plates. The thickness of the plates 8,9 is preferably 4-20 mm, most preferably 8-15 mm. The length of the plates in horizontal direction is preferably 4-20 cm.

[0104] The two metal pillars 8,9 are spaced apart, an opening extending horizontally through the leg 5 between the two metal pillars 8,9. This provides that a lifting or binding member, such as a cargo strap can be guided through the opening. This facilitates easy binding and/or lifting of the prefabricated cabin during transport thereof. This also facilitates rigidity of the leg. Preferably, the opening is at least 10 cm wide in horizontal direction, and at least 5 cm high (preferably equal to the distance between the plates 6,7) since hereby said advantages are considerable.

[0105] The two metal pillars 8,9 being metal plates 8,9 and spaced apart facilitates that the structure 6,7,8,9 as seen from side becomes cellular and extremely high rigidity can be achieved for the leg 5 with relatively small amount of metal material. The structure is in the preferred embodiment overall such that the metal plates 6,7,8,9 define the borders of the opening 13.

[0106] Preferably, the distance between the plates 6,7 is at least 5 cm, preferably 5-20 cm. These ranges facilitate considerably the aim to raise the prefabricated cabin a distance above ground so that a ventilation space is left below the prefabricated cabin without making the leg 5 unstable.

[0107] Said metal plates 8,9 are preferably at an angle relative to each other, preferably at 70-110 deg, most preferably at a right angle relative to each other. The angle provides that a relatively long (in horizontal direction) pillar plate 8,9 can be used and it can be simply positioned below the walls of the parallel to the walls.

[0108] The one or more metal pillars 8,9 are preferably welded to said first and second horizontal metal plates.

[0109] The vertical projections of the two metal pillars 8,9 are within the vertical projections of the adjacent walls, as illustrated in FIGS. 7-8. Thus, in general no unnecessary torque is formed. In particular, the vertical projection of one of the two metal pillars 8,9 is within the vertical projection of the first log end, and the vertical projection of the other within the vertical projection of the second log end.

[0110] As visible in FIGS. 3 and 4, the corner leg 5 comprises a first lateral support and positioning member 11 for a structure of the cabin box 2, in particular for a first log end 10a, to be fixed on the horizontal metal plate 6, and a second lateral support and positioning member 12 for a structure of the cabin box 2, in particular for a second log end 10b to be fixed on the horizontal metal plate 6, which lateral support members 11,12 protrude upwards from the first horizontal metal plate 6. Owing to said lateral support and positioning members, the leg 5 can provide not only firm vertical support for the cabin box but also the ability to give firm lateral support and to ensure accurate positioning.

[0111] In the preferred embodiment, the first lateral support and positioning member 11 is beside the first upper support face portion 6a for a first log end 10a and the second lateral support and positioning member 12 is beside the second upper support face portion 6b for a second log end 10b. In the prefabricated cabin 1, the first log end 10a of a first log 10 rests beside the first support and positioning member 11, in particular on the first upper support face portion 6a and a second log end 10b of a second log 10 rests beside the second support and positioning member 12 in particular on the second upper support face portion 6b.

[0112] The lateral support members are two vertical metal plates, which are at an angle relative to each other, most preferably at an angle 70-110 deg relative to each other, most preferably at a right angle relative to each other. The angle preferably is the same as the angle between the adjacent walls below the corner of which the leg 5 is positioned and/or the same as the angle between the first log end 10a and the second log end 10b.

[0113] The lateral support and positioning members 11,12 are placed against and fixed to the first log end 10a and second log end 10b, in particular in an inner corner formed between the first log end 10a and second log end 10b. This is illustrated in FIG. 8. The lateral support and positioning members 11,12 being in the inner corner provides that they are invisible outside the cabin box 2 making it possible to leave the outer corner of the cabin box 2 free of such members.

[0114] The cabin box 2 preferably also comprises a roof 14 as visible in FIG. 1. The cabin box 2 preferably also comprises a floor 15. The floor 15 is illustrated by broken line 15 in FIG. 8. The floor 15 is preferably placed to rest on a third upper support face portion 6c of the first horizontal metal plate 6 (shown in FIG. 6). Thus, the leg 5 can provide also a support face portion on top of which the floor 15 can rest. This is however not necessary, because the floor 15 could alternatively be provided or arranged in some other way, such as a floor could be mounted on the walls 3 of the cabin box 2, for instance.

[0115] The cabin box 2 preferably comprises one or more openings 16, such as window openings and/or door openings. The cabin box 2 preferably comprises a window mounted in a window opening and/or a door mounted in a door opening.

[0116] The prefabricated cabin 1 is preferably a prefabricated sauna cabin, preferably comprising in the interior 4 a heater and/or sauna benches. The heater could also be installed later in the interior 4, for example after transport and installation of the prefabricated cabin 1. The prefabricated cabin 1 could alternatively be some other kind of prefabricated cabin 1. It could be for instance a prefabricated storage cabin or a small prefabricated cottage cabin.

[0117] The leg 5 comprises a third upper support face portion 6c of the first horizontal metal plate 6, which is horizontally displaced from the aforementioned upper support face portions 6a,6b of the first horizontal metal plate 6 on which the first log end 10a and the second log end 10b rest. In particular, in the preferred embodiment visible in FIGS. 4-6, the upper support face portion 6c is on the opposite side of the first and second lateral support and positioning members 11,12 than the support face portions 6a,6b. Thus, a floor 15 can be positioned in the inner corner of the cabin box to rest on the leg 5 when this kind of structure is desired.

[0118] The prefabricated cabin 1 can be placed to stand on a base, such as a base illustrated in FIGS. 10 and 11, supported by the legs 5. Each leg 5 is arranged to carry part of the weight of the cabin box 2, the vertical reaction forces from the base 20 being transmitted via the second horizontal metal plate 7 of a support leg 5 to the one or more metal pillars 8,9 of the support leg 5 and via the one or more metal pillars 8,9 to the first horizontal metal plate 6 and via the first horizontal metal plate 6 to the cabin box 2 such as preferably to the log ends thereof.

[0119] For fixing the prefabricated cabin 1 to the cabin box 2, the first horizontal metal plate 6 of the leg 5 comprises fixing holes 17,18 (shown in FIG. 8). In particular, the first horizontal metal plate 6 of the leg 5 comprises a first fixing hole 17 through which a first fixing member extends vertically fixing the first log end 10a against the first upper support face portion 6a and a second fixing hole 18 through which a second fixing member extends vertically fixing the second log end against a second upper support face portion 6b. The first fixing hole 17 extends through the first upper support face portion 6a and the second fixing hole 18 extends through the second upper support face portion 6b.

[0120] For fixing the prefabricated cabin 1 to stand immovably on a base, such as a base 20 illustrated in FIGS. 10 and 11, the second horizontal metal plate 7 of the leg 5 comprises a fixing hole 19 (shown in FIG. 4) through which a fixing member, such as an anchor bolt, can be placed to extend for thereby fixing the leg 5 to a base 20.

[0121] The support leg 5 of a prefabricated cabin 1, as such, according to an embodiment, comprises a first horizontal metal plate 6 configured for supporting the cabin box 2 on top of it and a second horizontal metal plate 7 configured for being placed against a supporting base, the second horizontal metal plate 7 being at a distance below the first horizontal metal plate 6; and one or more metal pillars 8,9 between said first and second horizontal metal plates 6,7 connecting them fixedly to each other. Several preferred details of the support leg 5 have already been described above, where the support leg has been described together with the cabin box 2. In the following the structure of the support leg 5, as such, is further described.

[0122] The first horizontal metal plate 6 comprises a first upper support face portion 6a for a first log end 10a to be placed to rest on the first horizontal metal plate 6 and a second upper support face portion 6b for a second log end 10a to be placed to rest on the first horizontal metal plate 6.

[0123] The first horizontal metal plate 6 comprises a third upper support face portion 6c for a floor 15 to be placed to rest on the first horizontal metal plate 6. As mentioned, this is not necessary since the floor could be also otherwise mounted or provided.

[0124] In the preferred embodiment, the leg 5 comprises a first lateral support and positioning member 11 for a first log end 10a to be fixed on the horizontal metal plate 6, and a second lateral support and positioning member 12 for a second log end 10b to be fixed on the horizontal metal plate 6, which lateral support members 11,12 protrude upwards from the first horizontal metal plate 6. The lateral support and positioning members are not necessary, but advantageous for achieving a leg structure that is overall extremely efficient in terms of rigidity and functions provided. The lateral support and positioning members can be integral to each other and connected at their ends to each other as illustrated, but this is not necessary.

[0125] In the preferred embodiment, the first lateral support and positioning member 11 is beside the first upper support face portion 6a for a first log end 10a and the second lateral support and positioning member 12 is beside the second upper support face portion 6b for a first log end 10b.

[0126] In the preferred embodiment, the lateral support members 11,12 are two vertical plates, which are at an angle, preferably at a right angle relative to each other as illustrated. The lateral support members 11,12 form a corner and the first and second upper support face portions 6a,6b are on an outer side of a corner formed by the first and second lateral support and positioning members 11,12. Thus, the log ends 10a,10b can be placed on the outer side of them and said members 11,12 need not be visible to the outside.

[0127] The third upper support face portion 6c of the first horizontal metal plate 6 is horizontally displaced from the aforementioned upper support face portions 6a,6b of the first horizontal metal plate 6, preferably on the opposite side of the first and second lateral support and positioning members 11,12 than the first and second support face portion 6a,6b. Thus, a floor 15 can be positioned in the inner corner of adjacent walls of the cabin box 2 to rest on the leg 5 when this kind of structure is desired.

[0128] As mentioned, the one or more metal pillars are preferably welded to said first and second horizontal metal plates. Preferably, there are two of said metal pillars 8,9 between said first and second horizontal metal plates 6,7 connecting these fixedly to each other. The two support leg members 8,9 are preferably vertical metal plates, as illustrated. Preferably, the two metal pillars 8,9 are spaced apart, an opening extending horizontally through the leg 5 between the two metal pillars 8,9. The two metal plates 8,9 are preferably at an angle, preferably at a right angle relative to each other. The distance between the plates 6,7 is preferably at least 5 cm, preferably 5-20 cm.

[0129] For fixing the leg 5 to the cabin box 2, the first horizontal metal plate 6 of the leg 5 comprises fixing holes 17,18. In particular, the first horizontal metal plate 6 of the leg 5 comprises a first fixing hole 17 through which a first fixing member can be placed to extend vertically and a second fixing hole 18 through which a second fixing member can be placed to extend vertically. The first fixing hole 17 extends through the first upper support face portion 6a and the second fixing hole 18 extends through the second upper support face portion 6b. The leg 5 comprises a fixing hole 19 through which a fixing member, such as an anchor bolt, can be placed to extend for thereby fixing the leg 5 to a supporting base 20, of the installation site, such as to concrete blocks 21 thereof.

[0130] As for the shape of the first horizontal metal plate 6, preferably it comprises a first edge and a second edge which are at right angle, and the corner between the first and second edges is preferably slanted, such that a third edge extends between them at an angle relative to both of them, preferably 45 deg.

[0131] In an embodiment of a method of building a cabin, the method comprises providing a prefabricated cabin 1 as described anywhere above and illustrated in FIGS. 1,2,3, 7 and 8; and thereafter moving the prefabricated cabin 1 to be on a supporting base of a transport platform or of a transport container 30, said moving comprising placing it to stand on its support legs 5 on top of the supporting base of a transport platform or of a transport container 30, as illustrated in FIG. 9. After this, the method comprises moving said transport platform or a transport container 30 to proximity of the installation site, such as by truck. After this, the method comprises placing the prefabricated cabin 1 to stand on a supporting base 20 of the installation site, such on concrete blocks 21 thereof, as illustrated in FIG. 10. The concrete blocks 21 can be concrete plates for example. Concrete blocks are easy and quick to install, and in most case sufficient form of a supporting base for the prefabricated cabin 1 as presented. The supporting base 20 could alternatively be of some other kind, such as asphalt or dense sand foundation, for example.

[0132] After said placing the prefabricated cabin 1 to stand on a supporting base 20 of the installation site, the method preferably comprises leaving the support legs 5 unfixed to the supporting base 20. This is enabled by firmness of the leg structure, and moreover preferred in many cases, in particular if there is no particular need for anchoring the cabin 1 to its base. Leaving the support legs 5 unfixed is advantageous since in the structure of the prefabricated cabin 1 presented, the legs 5 are below the cabin box 2 supporting the cabin box 2 on top of it. Performing fixing, such as component positioning and accurate drillings, after the prefabricated cabin 1 stands on the supporting base 20 would consume additional time, e.g., due to the limited space.

[0133] Alternatively, the method can comprise after said placing the prefabricated cabin 1 to stand on a supporting base 20 of the installation site fixing the legs of the prefabricated cabin 1 to a supporting base 20 of the installation site, such as to concrete blocks 21 thereof. The fixing can be performed for example by anchor bolts 22 extending through fixing holes 19 of the legs 5. However, as mentioned this fixing is not necessary. Due to optionality of the fixing, the anchor bolt 22 is illustrated in broken line in FIG. 11.

[0134] The aforementioned step of providing a prefabricated cabin 1 preferably comprises providing logs 10; and placing support legs 5 on a base of a factory, such as a floor of a factory; and placing logs on the support legs 5, such that they rest on first horizontal metal plates 6 of the support legs 5; and fixing logs 10 on the support legs 5; and piling further logs on the logs fixed to the support legs 5.

[0135] Preferably, said placing logs 10 on the support legs 5 is performed such that a first log end 10a of a first log 10 rests on a first upper support face portion 6a of the first horizontal metal plate 6 and a second log end 10b of a second log 10 rests on a second upper support face portion 6b of the first horizontal metal plate 6. Thus, the log ends 10a,10b are as illustrated in FIGS. 1-3.

[0136] Said placing logs 10 on the support legs 5 is performed particularly preferably such that a first log end 10a of a first log 10 rests beside the first support and positioning member 11 and a second log end 10b of a second log 10 rests beside the second support and positioning member 12.

[0137] Preferably, in said fixing the first lateral support and positioning member 11 is fixed to the first log end 10a and the second lateral support and positioning member 12 is fixed to the second log end 10a.

[0138] Preferably, in said fixing the first log end 10a is fixed to the first upper support face portion 6a of the first horizontal metal plate 6, and the second log end 10b is fixed to the second upper support face portion 6b of the second horizontal metal plate 6, in particular by fixing members extending through the first metal plate 6. This fixing could be alternatively or additionally be implemented by fixing members extending through the members 11,12.

[0139] Generally, in said fixing logs 10 on the support legs 5, preferably one or more layers of horizontally oriented logs 10 can be fixed. More than one layers can be fixed, e.g., by long vertical screws for example as illustrated in FIGS. 2 and 3, but this is not necessary, since some other kind of fixing could alternatively be used.

[0140] The method may comprise at some point when desired, a step of binding the prefabricated cabin 1 immovably to its place, by a binding member such as a cargo strap, guided through an opening 13 extending horizontally through a leg 5 of the prefabricated cabin 1 between two metal pillars 8,9 of the leg 5. Thus, the leg structure can facilitate securing of the prefabricated to be immovable, e.g., during its transportation from the factory to the installation site. The method can particularly comprise the step of binding for instance between said placing the prefabricated cabin 1 to stand on its support legs 5 on top of a supporting base 31 of a transport platform or of a transport container 30 and said moving the transport platform or the transport container 30.

[0141] Generally preferably (although not necessarily), the prefabricated cabin is in particular a prefabricated log cabin, since in this context the leg structure is highly advantageous, for example due to facilitating fabrication of the prefabricated cabin at a factory, such as placing and piling of logs thereon, as well as due to facilitating supporting on support bases and movability of the cabin parts in different stages from initial steps of the fabrication to the final installation.
