Benefits of technology

[0009]As described above, in the cellar construction method of the completed building according to the present invention, the cellar can be newly constructed or added to the existing completed building without reconstructing the completed building, thereby reducing construction wastes, ultimately preventing environmental contamination and preventing construction materials from being wasted.
[0010]In addition, in the cellar construction method of the completed building according to the present invention, since a hydraulic cylinder is used as a press-in machine for inserting piles, noises and vibration can be eliminated, thereby providing environmentally friendl

Problems solved by technology

Since an existing completed building, in particular, a large-scale building, is heavy, in a case where a cellar area is secured by excavating the underground, the cellar area may tend to loosen the foundation soil that supports the building and may suffer from a high risk of collapsing.
Therefore, it has been practically difficult to secure or additionally constructing the cellar.
To solve the problem, in buildings without cellars or with insufficient cellar spaces, in particular, larg

second embodiment

[0066]FIGS. 16 to 19 illustrate a construction method of a cellar for a building completed according to the present invention.

[0067]In the construction method according to the second embodiment of the present invention, the cellar 12 can be constructed without perforating bottom concrete 2 in the completed building 1.

[0068]As shown in FIG. 16, in the construction method according to the second embodiment of the present invention, a foundation of one side of the completed building 1 is excavated, a press-in machine 6 is installed under the exposed bottom concrete 2, and piles 7a are inserted into the foundation at a position at which the press-in machine 6 is installed, thereby forming posts 7.

[0069]After forming the posts 7, the foundation around the posts 7 is excavated. After excavating the foundation, the press-in machine 6 is installed under the exposed bottom concrete 2 in the same manner as described above. Next, the piles 7a are inserted to form the posts 7. As the aforementi...

third embodiment

[0073]FIGS. 20 to 23 illustrate a cellar construction method of a completed building according to the present invention.

[0074]The cellar construction method according to this embodiment is suitable for constructing the cellar 12 in a small-scale completed building shown in FIG. 20.

[0075]In the construction method according to the third embodiment of the present invention, as shown in FIGS. 21 and 23, holes and slots are formed in bottom concrete 2 of outer edges of the completed building 1, supporting structures 5 are fixed to corresponding positions, and a press-in machine 6 is installed.

first embodiment

[0076]The installing of the supporting structures 5 and the press-in machine 6 are the same as those of the

[0077]As described above, the plurality of supporting structures 5 and the press-in machine 6 are installed on edges of the building 1, and piles 7a are inserted into the ground to form a plurality of posts 7 for supporting the hollow building 1. A foundation of the bottom concrete 2 under the building 1 is excavated and bottom and side surfaces of concrete 9 are finished to form the cellar 12.

[0078]Like the previous embodiment, in the present embodiment, in a case where the bottom concrete 2 is not strong enough to bear the reaction transmitted by the supporting structures 5, the strength can be enhanced by additionally installing a support plate 13 on or under the bottom concrete 2 when inserting the piles 7a into the bottom concrete 2 on the edges of the hollow building 1.

[0079]As described above, unlike in the first embodiment, in the second and third embodiments, since the...

Abstract

Disclosed is a construction method of a cellar for a building completed. The construction method includes fixing supporting structures to bottom concrete of the building; installing a press-in machine on the supporting structures; inserting posts for supporting the building into the foundation under the building by inserting hollow piles into the holes to then insert the piles into the underground using the press-in machine, stacking new piles on the inserted piles, and sequentially inserting the piles using the press-in machine; excavating a foundation under the bottom concrete of the building to prepare an underground space when the building is supported by the posts; and placing the concrete on the horizontal and vertical faces of the underground space prepared by the excavating the bottom concrete of the building.

Description

TECHNICAL FIELD[0001]The present invention relates to a construction method of a cellar for a building completed. More particular, the invention relates to a construction method of a cellar for a building completed, by which a cellar can be constructed by excavating the foundation under the building in a state in which the completed building remains intact. More particularly, the present invention relates to a cellar construction method of a building completed, which can simply and safely construct a cellar with low noises and reduced costs in a narrow space by installing a press-in machine in supporting structures fixed on the bottom of the building by allowing concrete to pass through the bottom of the building, safely supporting a plurality of posts formed by inserting hollow piles in a line on the building using the press-in machine, excavating the foundation of the building to selectively form an underground space, and placing concrete on the bottom surface of the underground s...
