Problems solved by technology

To install so many bolts will greatly increase the cost and reduce the economy
[0013] In addition, in order to ensure the adhesion between concrete and steel pipe piles, the position of the joint must be located below the distance from the upper part of the steel pipe pile that is greater than the diameter of the steel pipe pile. Very difficult problem with holes combined with bolts

Abstract

The invention relates to an apparatus and structure for connecting the head of the steel pile and the concrete footing. The system comprises a cylinder type vertical part having a number of bolts holes at the top side thereof and being inserted into the head of a steel piles, a flange part provided on the top of the vertical part so that the vertical part is suspended on the top of the steel pile, and a bottom plate integrally provided with the lower end of the vertical part for closing the cross section of the steel pile.

Description

technical field [0001] The present invention relates to a combination piece and a combination structure for combining a concrete foundation of a civil or building structure and the head of a steel pipe pile, in particular to a combination that can be easily installed on the head of a steel pipe pile so that the concrete foundation and the steel pipe pile form a Strongly bonded joints and joint structures. Background technique [0002] As the combined structure of the head of the steel pipe pile and the concrete foundation, the following two methods A and B are generally used. [0003] Method A is to embed the head of the steel pipe pile in the concrete foundation with a length greater than the diameter of the steel pipe pile, and form an external force (pressure or tension) that supports the head of the steel pipe pile at the part where the steel pipe pile is buried. Structure. [0004] Method B is to bury the head of the steel pipe pile in the conc...
