Title:
PILE HEAD REINFORCEMENT ASSEMBLY OF STEEL PIPE PILE
Document Type and Number:
WIPO Patent Application WO/2011/132894
Kind Code:
A3
Abstract:
The present invention relates to a pile head reinforcement assembly of a steel pipe pile and, more specifically, to an upper end reinforcement structure of a steel pipe for foundation work, for reinforcing the upper end portion of the steel pipe, which is drilled to the ground for reinforcement. The present invention has an object to provide a pile head reinforcement assembly of a steel pipe pile, wherein a blade section is inserted into a vertical steel bar, which is mounted at an upper end portion of a steel pipe, so that the blade section is secured on top of the steel pipe and protruded outwards from the periphery of the steel pipe. The pile head reinforcement assembly of a steel pipe pile, which is mounted with the blade section, is buried into the concrete of a foundation section. Therefore, when placing the steel bar for forming the foundation section, it is possible to reduce the amount of the steel bar mounted to the steel pipe and form a stable foundation section for supporting an upper structure. In order to achieve the object, the present invention provides a pile head reinforcement assembly of a steel pipe pile, comprising: a base plate mounted for preventing concrete injection into the steel pipe pile which is buried under the ground; a plurality of vertical steel bars vertically mounted to the steel pipe pile; and lateral ties for connecting the vertical steel bars. The pile head reinforcement assembly of a steel pipe pile according to the present invention further comprises: the blade section inserted into the vertical steel bar so as to be secured on top of the steel pipe pile, and protruded in the outward direction of the periphery of the steel pipe pile so as to improve the structural stability and durability of foundation expanding concrete.
