Background technology
As the head of steel pipe pile and the integrated structure of concrete foundation, adopt two kinds of methods of following A, B usually.
The A method is that the head of steel pipe pile is imbedded in the concrete foundation with the length greater than the diameter of steel pipe pile, forms the structure of the external force (pressure or pulling force) of the head of supporting to act on steel pipe pile in the part of imbedding steel pipe pile.
The B method is the head of steel pipe pile to be imbedded the degree of about 10cm in the concrete foundation, connects the head and the concrete foundation of steel pipe pile with stiffener, and support affacts the method for external force of the head of steel pipe pile from concrete foundation.
In the structure of A method, owing to imbed the interference of the steel pipe pile in the concrete foundation, cut off the main reinforcement of the bottom surface that is configured in concrete foundation, the configuration of reinforcing bar has the shortcoming that increases amount of reinforcement than B method complexity.Therefore, use the B method usually.
As the example of described B method, as shown in Figure 6, following structure is arranged, promptly after cross stiffener 6 welding were inserted in the inside of steel pipe pile 1, welded on the top that circular cover plate 5 is placed on steel pipe pile 1, again at the side of steel pipe pile 1 welding stiffener 3.But, in these existing structures,, be difficult to utilize the weight of cross stiffener 6 to be provided with because the effect of cover plate 5 is limited, expense is also higher.Especially must weld stiffener in the side of steel pipe pile 1, weld job also needs a lot of manpowers and expense.
For solving such problem, developed Korean Patent No. 229166.But this scheme remains the top that the parts that combine with cross stiffener and cover plate is arranged on steel pipe pile, does not still address the above problem.
