Description: This invention relates to an extra super multi-storey building of about 200 storey construction and to the structure thereof. In recent years, the concentration of population at urban area has become increasingly drastic, and in accordance with this, various urban problems have arisen. In particular, shortage of land has become acute. Although various opinions are presented as reasons against building them, the realization of extra super multi-storey buildings for the higher utilization of land is desired. In addition, in accordance with the rapid development of recent information-oriented society, the capacity of buildings to accept computerized functions is in demand more than ever. FR-A-1 230 543 (cf. the preamble of claim 1) discloses an extra super multi-storey building in which sky lobbies communicate among a plurality of extra super multi-storey towers, the sky lobbies being provided between multi-storey units stacked one above another to form the towers. Direct elevators from ground level serve the sky lobbies, and local elevators from the sky lobbies serve the floors of the multi-storey units. Now, some super multi-storey buildings have been constructed at present time, but owing to technical limitations, only buildings as high as 100 storeys have been built in most countries. In Japan, technical innovation for the construction of super multi-storey buildings have been highly promoted, but since Japan is a most earthquake-prone country, the number of building storey cannot match those in other countries, and only super multi-storey buildings as high as 75 storeys have been attempted. In addition, since most of the super multi-storey buildings which are now under construction have limitations in the number of storeys as well as floor areas, they are built only as office buildings and hotels exclusively. A super multi-storey building which can function as a small town by providing the facilities required for daily life has not yet been constructed. The present invention has been developed in the view of these circumstances, and it allows one to construct extra super multi-storey buildings as high as 200 storeys with the facilities required for urban life such as commercial facilities and sports facilities as well as offices, hotels and residences in one extra super multi-storey building and allow one to realise an extra super multi-storey building which may be regarded as one small town. The invention provides an extra super multi-storey building comprising a plurality of extra super multi-storey towers and sky lobbies communicating among the towers, the sky lobbies being provided between tower-like super multi-storey units stacked one above another to form the structure of the said towers, characterised in that each sky lobby comprises girders which constitute a monolithic structural connection between the towers at the level of the sky lobby, and there is a space truss at the outside of each unit. In the accompanying drawings: Figs. 1 to 9 show one embodiment according to the present invention, in which: Fig. 1 is a perspective view of an extra super multi-storey building; Fig. 2 is a vertical sectional view of the building; Fig. 3 is a plan view of an entrance floor; Fig. 4 is a plan view of a second floor; Figs. 6 and 7 are plan views of respective sky lobbies; and Figs. 5, 8 and 9 are plan views of respective super multi-storey units. 1, 2, 3 --- extra super multi-storey tower; 4 --- sky lobby; 5 --- shuttle elevator; 6 --- sightseeing tower and high-rise garden (sky dome); 7 --- local elevator; 8 --- structural column; 9 --- structural beam; 10 --- space truss; 11 --- girder; a ---super multi-storey unit. The extra super multi-storey building illustrated in the drawings comprises an extra super multi-storey tower 1 of about 200 storeys, two extra super multi-storey towers 2 of about 150 storeys, and one extra super multi-storey tower 3 of about 100 storeys, each constructed by setting up two to four tower-like super multi-storey units a of about 50 storeys and about 50 m in diameter (floor area is about 2,000 m 2 /storey), a sky lobby 4 provided about every 50 storeys, four shuttle elevators 5 leading to these sky lobbies 4 from the ground, and a sightseeing tower and high-rise garden (sky dome) 6 provided at the rooftop of the extra super multi-storey tower 1. Main facilities such as offices, hotels and residences are arranged at each of the extra super multi-storey towers 1, 2 and 3. However, for example, if the portion up to the 100th storey is arranged to be offices, the portion from the 100th to the 150th storey is arranged to be hotels (including residential area), and the portion up to the highest floor above the 150th storey is arranged to be residences, it is possible to prevent confusion of traffic lines and simultaneously to keep privacy. The sky lobby 4 becomes a traffic contact point of the respective extra super multi-storey towers 1, 2 and 3, and it is constructed about 5 or 6 storey high. The lowest floor is constructed as a floor only for service and the remaining floors are constructed for general use including an emergency floor. For example, commercial facilities such as stores and restaurants, cultural facilities such as library and art museum, sports facilities such as athletic fields and swimming pools, sightseeing facilities, heliports and other necessary facilities for urban life can be provided on the service floor and the floor for general use (refer to Figs. 3, 4, 6 and 7). In addition, the facilities necessary for urban life such as commercial facilities are also provided on the floors close to both basement floors and floors above the ground as occasion demands, similar to those at the sky lobby 4 (refer to Figs. 3 and 4). The shuttle elevators 5 are main elevators in this building, and a plurality of local elevators 7,7 are also provided in each of the extra super multi-storey towers 1, 2 and 3 so as to be capable of going back and forth to each floor of each super multi-storey unit a from the sky lobby 4. On the basis of such a plan, it is possible to get to each floor of each super multi-storey unit a by riding on the shuttle elevator 5 from the ground to get to the nearest sky lobby 4 and then changing to the local elevator 7 in each of the extra super multi-storey towers 1, 2 and 3. In addition, it is possible to substantially lead daily life without going outside, using the facilities such as stores available in the sky lobby 4 and on the floors nearest to both the basement floors and the floors above the ground. Moreover, since extra super multi-storey buildings cannot avoid experiencing high stresses once an earthquake happens, it is preferable to construct extra super multi-storey buildings using high-strength materials. Accordingly, an extremely high rigid steel pipe concrete column is used as a structural column 8 for each extra super multi-storey tower 1, 2 or 3, and the columns 8 are fitted to the inside and the outside of each extra super multi-storey tower at given circumferential intervals. Furthermore, the amount of cast-in-place concrete is decreased to a minimum and, at the same time, the duration of construction work is shortened by placing most of the concrete of the column 8 prior to the erection and then by placing only a portion of concrete on site for joint portions or the like which are necessary to design. Steel beams are used as structural beams 9 for each extra super multi-storey tower 1, 2 or 3, and the steel beams 9 are erected along the circumferential direction of each extra super multi-storey tower 1, 2 or 3 on every floor between inner columns 8 and between outer columns 8 or radially between the inner column 8 and the outer column 8, respectively. Moreover, at the outside of the outer structural columns 8 of each extra super multi-storey tower 1, 2 or 3, a space truss 10 is constructed over the whole circumference of each super multi-storey unit a , and thus the rigidity of the circumferential surface of each extra super multi-storey tower 1, 2 or 3 is remarkably raised by such a construction. Furthermore, the extra super multi-storey towers 1, 2, 3 are monolithically connected with one another every 50 storey by girders 11 composed of large type trussed beams or the like, and thus the horizontal rigidity of the overall building is remarkably raised by such a construction and, at the same time, the safety of the overall building is enhanced by installed various seismic response control devices using the girders 11. The floor of each storey in each super multi-storey unit a is constructed using composite floor plywoods, in order to obtain a reduction of the amount of cast-in-place concrete and a light weight of floor load. Simplification and omission of external wall work and further shortening construction time are achieved by totally constructing the external walls of each super multi-storey unit a by means of curtain wall construction. In addition, an improvement of construction efficiency is achieved by lifting the curtain wall, with the aid of a lift cr the like, to the floor to be set up, so as to avoid inconveniences in the erection of framing, using a fitting machine only for curtain wall in fitting work, and further, by adopting a large-type unit method, but not a so-called "knock-down method". As described above, the extra super multi-storey building and its structure according to the present invention can eliminate the problems of land shortage, contribute to the rapid development of information-oriented society, and further, give a great contribution to the improvement of both residential environment and urban environment.
