DOWN-WARD CONSTRUCTION METHOD OF THE UNDERGROUND SLABS AND RETAINING WALLS BY THE SLIM-TYPE COMPOSIT FLOOR SYSTEM CONSISTED OF THE ARCHITECTURAL CONPOSIT DEEP DECK AND UNSYMMETRIC H-BEAM WITHOUT PRELIMINARY WALL-ATTACHED SUPPORT BEAMS AND SUB-BEAMS OF THE FLOOR

摘要

The invention basement exterior walls (concrete retaining wall) and H-type file on the middle pillar wall adjacent to the retaining wall purchase, and then go through the asymmetric H-shaped slender beams in these H-type file, dance, performed by digging deep deck plate and at the same time as the asymmetric H-shaped composite slim beam to form a composite floor structure and basement with exterior walls, basement can significantly reduce the floor height, border security and the outer wall of the basement will omit the middle of the floor beams and the floor on thin composite structures and underground station simultaneous placement and simultaneous placement of exterior wall construction method that can significantly shorten the air. ; The present invention includes a first step of forming a retaining wall H-shaped file is embedded at certain intervals along the outer perimeter of the building to be constructed planning unit; A second step of installing the center pillar file location inside the building; A third step of installing underground outer side file location adjacent the retaining wall; A fourth step for applying an teopa to a predetermined depth the part of the earth retaining wall and the center file is to be exposed; The fifth step of the horizontal and vertical directions H Beam H Beam Beam installation files between the center and side files; The sixth step of forming a slab at the bottom of the dancing ground plan of the transverse H Beam install a deep deck plate; And further comprising a seventh step the outer wall and the basement to the co-casting and the slab concrete curing to form a composite floor structure, wherein the gihayeo teopa sequentially repeated and, at the same time to a predetermined depth to form the continuous phase before the predetermined lower level, and the lowest provides a thin composite floor system with simultaneous placement and underground backhand simultaneous installation of exterior wall construction method characterized in that it performs the floor and foundation.
