DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

[0020] In the description and the claims below is described a super high-rise building having a main support structure of reinforced concrete. The external walls, facades, are typically of the non-load bearing type, and may be made of glass, for instance.

[0021] FIG. 1 shows an example of a prior art super high-rise building having a main support structure of reinforced concrete, the external shape of the building being square and also the main support structure being square. The outer walls of main support structure are formed at a distance of about from each external wall of the super high-rise building. As an example, the length of each external wall is about 60 to 70 metres.

[0022] As can be inferred from FIG. 1 in case that an extensive fire breaks out it may spread around the main support structure and thus around one or more floors, i.e. it may encircle the whole super high-rise building.

[0023] As can be seen from FIGS. 2 to 12 by designing a main support structure 10 of reinforced concrete of a super high-rise building 1 in the way shown, it is possible to minimize the risk that an extensive fire will encircle the whole super high-rise building, i.e. spread around one or more floors.

[0024] FIGS. 2 and 14 show a first embodiment of a super high-rise building 1 having a main support structure 10 of reinforced concrete. A base 20 of said super high-rise building is schematically shown in the form of a square. It should be noted that the shape of the base 20 could be any suitable shape, such as a quadrangle, a parallelogram, a parallelepiped, a rectangle or a square.

[0025] The super high-rise building 1 has a height h in a vertical direction, see FIGS. 13 and 14. The height h may be form about 100 metres up to 500 metres or more.

[0026] The reinforcement of the concrete of at least said main support structure 10 may comprise a material selected from the group consisting of steel, glass fibre and carbon fibre or a combination thereof.

[0027] The main support structure 10 is formed of at least two walls 11. Each of the walls 11 may be a fire proof wall. Each wall 11 extends all the way between diametrically opposed external wall corners 13 of said base 20.

[0028] Each of the walls 11 is made of reinforced concrete. Each of the walls 11 may have a flat shape and extend vertically from the base 20.

[0029] As can be inferred, the two walls 11 intersect each other. Depending upon the structure of the super high-rise building 1 and thereby the main support structure 10 said walls may intersect each other at an intermediate portion 14 of respective wall 11. Said intermediate portion 14 may form a cross portion or a centre portion of respective wall 11 of said main support structure 10, as shown in

[0030] FIGS. 2 to 14, but it is not necessary. Said intermediate portion 14 of each wall 11 extends from said base 20 to an uppermost portion of said super high-rise building 1 or to a top end la of the super high-rise building 1, i.e. along the height or whole height of the super high-rise building 1, see FIGS. 13 and 14.

[0031] Each wall 11 may extend vertically from the base 20 along the height h of the super high-rise building 1. The super high-rise building 1 comprises a plurality of floors 15 which are separated from each other by joists 17, one joists 17 for each floor 15, see FIG. 14. The walls 11 extend from the base 20 through all floors 15 and joists 17.

[0032] By providing a main support structure 10 as mentioned above, at least four main confined spaces 100 are arranged each extending from said base 20 to the top end of said super high-rise building 1.

[0033] Furthermore, at each external wall corner 13 associated to each wall 11, at an external end 16 of respective walls 11 is arranged an external wall support structure 30 extending horizontally from said end 16 along a portion of a respective adjacent external wall 40 and to a height where said adjacent external wall 40 ends.

[0034] As seen in FIGS. 3 to 5, for instance, to further improve the stability and rigidity of the super high-rise building 1, at the external wall corner 13 associated to each wall 11, each external wall support structure 30 forms a corner support structure 31 by arranging support walls 32 extending at right angle from each adjacent external wall 40 to said wall 11 such as to form said corner support structure 31. Said corner support structure 31 may form a closed corner support structure 31. Preferably, the walls 11 extend through each of said corner support structures 31 to the external wall corner 13. Said corner support structure 31 has preferably the form of a quadrangle, such as a square or rectangle, and extends to a height where said adjacent external walls 40 ends.

[0035] In the embodiment shown in FIG. 3, the intermediate portion 14 of respective wall 11 is provided with at least a pair of opposed internal support structures 50. The ends 51 of each internal support structures 50 extend to a respective wall 11.

[0036] The opposed internal support structures 50 may, as shown in FIG. 4, form a central support structure 52 at the intermediate portion 14 of respective wall 11. The central support structure 52 is formed of two pairs of opposed internal support structures 50. The central support structure 52 has preferably the same shape as the external shape of the super high-rise building 1. Furthermore, inner support structures 53 may extend from the intermediate portion 14 of respective wall 11 to a respective one of the internal support structures 50 and form a right angle with the respective internal support structure 50. The central support structure 52 may thus form a plurality of first vertically extending shafts 54. Said first vertically extending shafts 54 may form shafts for service functions of the super high-rise building, which function are selected from the group consisting of lifts, ventilation equipment, electric cables and piping and so forth.

[0037] The embodiment shown in FIG. 5 is similar to the one in FIG. 3, but without the opposed internal support structures 50.

[0038] The embodiment shown in FIG. 6, to even further improve the stability and rigidity of particularly the corners of the super high-rise building 1, at least a further corner support structure 34 is arranged adjacent each corner support structure 31 and along the walls 11 towards the intermediate portion 14 of respective wall 11. Said further corner support structure 34 has preferably the form of a quadrangle, such as a square or a rectangle. Preferably, the walls 11 extend through each of said further corner support structures 34.

[0039] The so formed corner support structures 31 and said further corner support structures 34 form vertically extending shafts 33 for service functions of the super high-rise building 1, which functions are selected from the group consisting of lifts, ventilation equipment, electric cables and piping and so forth.

[0040] FIG. 7 shows an embodiment of the super high-rise building 1 which is a combination of the embodiments shown in FIGS. 4 and 6.

[0041] As seen in the embodiment shown in FIG. 8, in case of said base 20 being shaped as a quadrangle, but not necessary, said at least two walls 11 are each formed of a plurality of quadrangular support structures 70 mutually having the same form. That the intermediate portion 14 of respective wall 11, a centre quadrangular support structure 70a is formed. At each corner 71 of said centre quadrangular support structure 70a said plurality of quadrangular support structures 70 may be connected to each other at diametrically opposed corners 72, preferably such that respective side 70b, 70c of the centre quadrangular support structure 70a and each quadrangular support structure 70a is parallel with a respective side 20a of the base 20, and possibly with a respective one of the external walls 40.

[0042] In the embodiment shown in FIG. 9, the base 20 has a basic quadrangular shape with opposed inwardly angled external wall portions 41 extending from opposed external wall corners 13 and connected to each other by an external wall 42. In the same way, as is shown in FIG. 3, the intermediate portion 14 of respective wall 11 is provided with at least a pair of opposed internal support structures 50. The ends 51 of each support structure 50 extend to respective wall 11.

[0043] In case the base 20 has a more rectangular shape, an obtuse angle a formed between the two walls 11 of the support structure 10 has a maximum value of about 130.

[0044] In the embodiment shown in FIG. 10, the base 20 has the form of an octagon, but the support structure 10 has the same shape as the one shown in FIG. 5.

[0045] However, the base may have, in an embodiment not shown, more or less than 8 corners.

[0046] In FIGS. 9 and 10, in the same way as is shown in FIGS. 3 to 5, at the external wall corner 13 associated to each wall 11, an external wall support structure 30 forms a corner support structure 31 by arranging walls 32 extending from each adjacent external wall 40, 41 to said wall 11 such as to form said corner support structure 31. Said corner support structure 31 may form a closed corner support structure 31. Preferably, the walls 11 extend through each of said corner support structures 31 to the external wall corner 13. Said corner support structure 31 extends to a height where said adjacent external walls 40, 41 end.

[0047] As shown in FIGS. 11 and 12, to even further improve the stability and rigidity of the super high-rise building 1 and to reduce the consequences of a major explosion, for instance, further vertical support structures 80 and centrally arranged vertical support structures 90 are provided in the confined spaces 100 formed between the arms 11. Said centrally arranged vertical support structures 90 preferably having each a straight side structure 91 directed towards the centre of the building.

[0048] The vertical support structures 80 and centrally arranged vertical support structures 90 are preferably so arranged relative to each other and the vertical support structures 80 individually that corridor 110 and 111 are formed.

[0049] At the side of one of the straight side structure 91 (to the right) shown in FIG. 12 directed towards the centre of the super high-rise building shafts 54 are formed.

[0050] As in the embodiments above, the main support structure 10 is formed of two intersecting walls 11, each extending all the way between diametrically opposed external wall corners 13 of said base 20, 20, 20.

[0051] In all of the embodiments of the super high-rise building 1 according to the invention at least four main confined spaces 100 are formed, which each provide its own fireproof cell. Fire proof doors may be provided in the walls 11 between the fireproof cells so formed. Should fire proof doors be provided the walls 11 between the fireproof cells, they are preferably arranged at a spacing of 4 to 5 floors 15.

[0052] FIG. 13 is a schematic sectional side view of the embodiment of a super high-rise building 1 having a main support structure 10 of reinforced concrete according to the invention as shown in FIG. 6, for instance. As a non-limiting example, the corner support structures 32, 34 extend to different heights, wherein the corner support structures 32 form outermost corner support structures 32, and the further corner support structures 34 may form intermediate corner support structures 34 and innermost corner support structures 34. The outermost corner support structures 32 may be the lowest and may extend preferably to a height of about 100 metres. The intermediate corner support structures 34 may extend preferably to a height of about 300 metres and the innermost corner support structures 34 may extend preferably to a height of about 500 metres.

[0053] It should be noted that the walls 11 of the support structure 10 in all embodiments mentioned above shall have such strength that they preferable will withstand an extensive fire and/or major explosion.
