Problems solved by technology

Since this method uses special reinforcing beams and panels, its structural cost is high and uneconomical
[0013] In addition, this method cannot make full use of the open space between multiple buildings connected by corridors

Embodiment 2

[0060] The special effect of the second embodiment is that the interior space of the building can be effectively expanded, because the upper building 11 is formed on a plurality of existing buildings 2 .

[0061] Furthermore, new columns 8 located on the periphery of several buildings 2 can be connected with the new structure 4 . This ensures that there are no long beams and therefore strength.

[0062] In the first and second embodiments described above, at least a part of the existing building 1 can be demolished when the upper buildings 6 and 11 are completed. It is also possible to build a new structure to match the new structures 4 and 9 in the space formed after the demolition.

[0063] At this time, a new structure constructed in the part demolished of the existing building 1 is combined with the new structures 4 and 9 in the outer walls and inner spaces.

[0064] Demolition of part of the existing building 1 may be the demolition of only the connecting corridor 3 (pa...

Abstract

The invention provides a method of expanding an existing building having a structure where buildings are connected to each other by means of connecting corridors. The method is capable of expanding the existing building upward while it is used, securing sufficient strength of the building, and effectively utilizing empty spaces of the building. In the method of expanding an existing building having a structure in which buildings are connected to each other by means of connecting corridors, new structures each having an upper story portion that is higher than the existing building by a height equivalent to one or more stories are constructed on both sides of each connecting corridor. The upper story portions of the new structures are connected to each other so as to straddle the connecting corridors. Consequently, upper story portions are formed also above the connecting corridors.

Description

technical field [0001] The present invention relates to a method of enlarging an existing building and a building enlarged using this method. Further, for an existing building composed of a plurality of buildings connected to each other through corridors, the present invention relates to a method of enlarging the existing building which can ensure sufficient strength and fully utilize vacant space, and use The method expands the building. The present invention can also expand an existing building upwards in the state it is being used. Background technique [0002] If you want to renovate a two-story building into a three-story building, because of the strength relationship of the original columns, walls and beams, etc., generally the top of the two-story building will not be used as the top of the new three-story building. floor. So people had no choice but to completely demolish the existing two-storey building and build a new three-storey building on the vacant land. B...
