BRACKET SUPPORT TYPE DOWNWARD CONSTRUCTION SYSTEM AND CONSTRUCTION METHOD USING THE SAME

摘要

The present invention relates to a bracket supporting type down frame placing system and a method of placing down frame using the same, wherein the load of the concrete is pre-constructed during the construction of the underground structure while the concrete is being placed on the beam and slab formwork of the construction layer. Rather than a suspension and support system using a suspension material on an upper slab, a mobile support bracket fixed to a frame pillar and a support girder supported by a column by the mobile support bracket directly support the frame pillar. The present invention relates to a down frame pouring system of support type and a down frame pouring method using the same.;According to the present invention, it is possible to solve the conventional problems caused by the load of the lower concrete acts on the upper slab, and it is possible to construct the beam and slab of the lower layer irrespective of the construction state of the upper slab by the column support. There is an advantage that the shortening of the period is also possible.
