CONSTRUCTION FOR FOUNDATION WORK OF BUILDING

摘要

A foundation structure of a building is provided to increase the friction force generated after constructing a pile, to approach the friction force to a desired value, and to minimize the cost for foundation piles. A foundation structure of a building comprises plural concrete piles(P) hammered and erected at a ground and exposed of the upper part to a certain height to finish the front end so as to expose iron bars; plural auxiliary piles(100) erected like a polygon around the pile to increase the friction force; a semicircular groove(110) formed on the upper outer periphery of the auxiliary pile; a circular ring(150) welded on the semicircular groove; iron bars(200) settled at the upper side of the circular ring and curved in a polygonal shape to be welded on the outer surface of the auxiliary pile; a square foundation board formed at a group of the pile and the auxiliary pile together by pouring concrete; and a foundation floor integrally formed with the square foundation board at the upper side of the ground and the square foundation board by arranging iron bars and pouring concrete.
