DETAILED DESCRIPTION OF THE INVENTION

[0016] The disclosed ground anchoring element comprises a support element for the subframe, which are angled brackets with angled joint 1a or angled brackets 1b and a support element nut permanently attached to the angled brackets, being a bracket nut 2, also a threaded rod 3, adjusting nuts 4, 5 and a support plate 6, whereas the ground anchoring element is to be fastened to a small-building's subframe, which is a framework made of beams on which the small-building rests.

[0017] The angled bracket 1a, 1b is meant to be fastened to the subframe of a small-building, whereas in one embodiment, it has been done with the bracket 1a that has an angled-joint (FIG. 1) and, in the other, the bracket 1b has a straight-joint (FIG. 2). The angled-joint bracket 1a comprises two brackets joined at a right angle.

[0018] The angled bracket 1a, 1b is rectangular (right angled) and connected to the lower part of the subframe (preferably on its inner side) in a way that the beam of the subframe is resting on the bracket. The bracket is perforated and fastened by screws. The bracket is preferably made of metal but also other rigid materials can be used instead.

[0019] A bracket nut 2 has been fastened (e.g. welded) to the inner side of the bracket 1a, 1b. In the event of bracket 1a, the bracket nut 2 is fastened at the connecting point of the brackets.

[0020] A threaded rod 3 has been inserted into the bracket nut 2, whereas in the beginning, the threaded rod 3 is screwed into the bracket nut 2 in a way that it does not extend out of the bracket nut 2 (towards the sky). Where necessary, the threaded rod 3 can be screwed out of the bracket nut 2 top (to adjust the height of the subframe when installing the small-building). The other end of the threaded rod 3 is for immediate insertion into the ground.

[0021] Separate adjustment nuts 4, 5 that can be freely moved have been added to the part of the threaded rod 3 that is below the bracket nut 2.

[0022] After the adjustment nuts 4, 5, a support plate 6 with an opening in the middle has been added to the threaded rod 3; the plate can be round disc as well. The support plate 6 is preferably made of metal but also other rigid materials can be used instead.

[0023] The support plate 6 is fastened to the threaded rod 3 with a tie, e.g. a cable tie, wire, ribbon, that allows it to move freely. The purpose of the tie (not on the figure) is to keep the support plate 6 on the threaded rod 3 when placing the subframe directly onto the ground and later, to move the support plate 6 on the rod when adjusting the height of the subframe, where necessary.

[0024] The angled bracket 1a, 1 b, the threaded rod 3, the bracket nut 2, the adjustment nuts 4, 5 and the support plate 6 with the tie comprise the footing member of the small-building's subframe (foundation) fastened to a small-building's subframe, which is preferably a framework of wooden beams. The subframe can also be made of other material.

[0025] Thus, the disclosed invention is an adjustable in height (to be levelled) and reusable ground anchoring element attached to a small-building's subframe which does not require an even prepared ground surface and foundation in any other way, as it itself is a stationary foundation.

[0026] The subframe (foundation) of a small-building is made as follows. A framework is made of beams or a prefabricated subframe is used. Angled bracket 1a is screwed to the lower side of the inner corners of the subframe. Where necessary, brackets 1b are added to other parts (inner and/or outer) of the subframe. A threaded rod 3 is screwed from below edge of bracket 1a, 1b into the bracket nut 2 that has been fastened to the bracket 1a, 1b; the threaded rod 3 is screwed into the bracket nut 2 not through it; the other, long end of the threaded rod 3 is left out of the bracket nut 2. Separate adjustment nuts 4, 5 are screwed onto the threaded rod 3 up to the bracket nut 2, touching it. After the adjustment nuts 4, 5, a support plate 6 is placed, through the opening in the middle, onto the threaded rod 3. The support plate 6 is fastened to the threaded rod 3 with a tie, preferably a cable tie, so that it can move. The use of a tie is necessary because otherwise the support plates 6 would come off the threaded rods 3 when placing the subframe on its place, and when the subframe is on the ground, it must be possible to move the support plates 6 around the threaded rods 3.

[0027] When all footing members have been fastened to the subframe, the subframe is put in place on the ground and the ends of the threaded rods 3 that extend outside the nuts 2 are run deep into the ground until the support plate 6 is touching the ground. By running the threaded rods 3 into the ground, the subframe is anchored stationarily to the ground. Holes may be made into the ground for the threaded rods 3 beforehand. An air gap is left between the subframe and ground; it is between the support plate 6, adjustment nuts 4, 5 and the bracket nut 2.

[0028] Where necessary, the height of the subframe can be adjusted on the ground, i.e. to lift the subframe higher from the ground and to make it level. This adjustment can be done in two ways: from the ground or from the subframe of the small-building. To adjust the height a little (e.g. to make the building level), adjustment nut 5 is screwed towards the support plate 6. Another option is to screw the adjustment nuts 4, 5 on the threaded rod 3 away from the bracket nut 2, then to screw the adjustment nuts 4, 5 together, and by screwing these simultaneously on the threaded rod 3, the threaded rod 3 will turn in the bracket nut 2. As the support plate 6 is on the ground and the threaded rod 3 is stationary in the ground, this activity will either lift or lower the subframe.

[0029] The final step is to place the small-building onto the subframe.
