COMPOSITE FOUNDATION STRUCTURE FOR POST AND CONSTRUCTION METHOD FOR POST USING THE SAME

摘要

The present invention relates to a pile foundation structure of a pillar (100) having a pillar (110) and a bottom plate (120) coupled to a lower end of the pillar (110), comprising: a steel pipe pile (200) buried in the ground; A lateral permanent mold 310 spaced around the outer periphery of the steel pipe pile 200; A lower permanent mold 320 installed to close an area between the lower end of the side permanent mold 310 and the steel pipe pile 200; A filler (C) filled in a space formed on the outer side of the steel pipe pile (200), the inner side of the side permanent mold (310) and the upper side of the lower permanent mold (320); And an anchor 400 having a lower portion embedded in the filler material C and an upper portion coupled to the bottom plate 120. The present invention provides a pile foundation composite structure having a superior workability and work safety, , The stress concentration region can be efficiently reinforced and the manufacturing cost can be reduced.
