MULTIFUNCTIONAL AND MULTIPURPOSE APPARATUS FOR REINFORCING THE HEAD OF PILE COMPOSED OF LITTLE MEMBERS AND CONSTRUCTION METHOD OF THE ENLARGED FOUNDATION USING THE APPARATUS

摘要

Multi-function and multi-purpose pile head reinforcement device consisting of a small number of component members in accordance with the present invention, a portion above the top of the rebar in the pile is installed to a predetermined depth arranged such that the inserted plurality of rebar will constitute one of the cylindrical structure; And it is spaced a predetermined distance to a number of external reinforcement installed in the multi-layer laminate strip forming the pillar structure reinforced with rebar; The slip that was mounted to the inner surface the upper end of the pile, a Rebar is inserted in the top of the pile is spaced apart from the inner wall surface of the peg to secure the position of the rebar to be inserted into the top of the pile so that it can be accurately Array Tighten the integrated steel production to bump into the nuts and bolts and rebar fixing device combined with the sliding jaw and shear yeongyeoljae using a stud bolt head flyer also yeongyeoljae role; The upper end of the inner piles are installed on the lower wall, and the integrated steel production to tighten the bolts and nuts to slip bump, Combine slip and shear jaws yeongyeoljae by the head of the stud bolts to shear device yeongyeoljae role; To fill in for the casting of concrete, a disk-shaped lower base plate more predetermined depth from the lower end of the rebar embedded in piles installed in the lower position; And its one end is connected to the lower end of the bolt member and the reinforcement of the sliding jaw, and a combination shear yeongyeoljae device, the other end is configured to include a lower fixed base plate member for supporting the bottom support plate and fixed by being connected to the lower base plate.
