Description

1 shows an embodiment of the connection structure of the present invention. FIG. 1A is a longitudinal sectional view of an essential part, and FIG. It is a figure which shows the pile head metal fitting in the connection structure of FIG. 1, and the bolt rotation stop metal fitting attached to the back surface of this pile head metal, FIG. 2 (a) is a top view of a pile head metal fitting, FIG. FIG. 2C is a plan view of the bolt rotation stopper, and FIG. 2D is a front view of the bolt rotation stopper. 3A and 3B are views showing an intermediate fitting and an eccentric washer attached to the intermediate fitting in the connection structure of FIG. 1, FIG. 3A is a plan view of the intermediate fitting, FIG. 3B is a side view of the intermediate fitting, and FIG. is a plan view of the eccentric washer, FIG. 3 (d) is a cross-sectional view of an eccentric washer. FIG. 4A shows a fixing bracket provided on the lower end of the pedestal of the superstructure attached on the intermediate bracket of FIG. 3, FIG. 4A is a plan view of the fixing bracket shown by cutting the pedestal portion, FIG. ) Is a side view in which a part of the fixing bracket is omitted. It is the perspective view which abbreviate | omitted partially which shows the connection structure of FIG. FIG. 6 (a) is a plan view showing a steel pipe pile embedded with a misalignment from the planned embedding position (axial core position of the pedestal of the upper structure). FIG. 6 (b) is a plan view showing a state in which the pile head fitting set in the pile head space of the steel pipe pile is rotated and adjusted in accordance with the misalignment. FIG. 7 (a) is a diagram for explaining a construction procedure performed after the construction procedure shown in FIG. 6, and FIG. 7 (a) shows a position where the connecting shaft attached to the adjustment hole of the pile head metal fitting shown in FIG. FIG. 7B is a plan view showing the positional relationship between the intermediate metal fitting and the connecting shaft before the orientation is adjusted. . FIG. 8A is a diagram for explaining a construction procedure performed after the construction procedure shown in FIG. 7, and FIG. 8A is a plan view showing the positional relationship between the intermediate metal fitting and the connecting shaft after the orientation is adjusted, and FIG. These are top views which show the construction procedure from Fig.6 (a) to FIG. 8 (a). It is a figure explaining the construction procedure performed after the construction procedure shown in FIG. 8, and is a top view which shows the state which attached the eccentric washer on the intermediate metal fitting shown to FIG. 8 (a), (b). It is the side view which abbreviate | omitted partially showing an example of the steel pipe pile used in the Example of the connection structure of this invention shown in FIG. It is a description side view of the state which supported the solar cell module as a superstructure, or the mount for solar cell arrays by the steel pipe pile using the connection structure of this invention. It is a top view which shows the embedding location of the pile which is a part of connection structure of the solar cell module or the solar cell array mount as the upper structure shown in FIG. 11, and the mount.

As shown in FIGS. 2 (a) and 2 (b), the pile head fitting 30 is disk-shaped, and its diameter is set slightly smaller than the inner diameter of the pile head 24, and moves in the circumferential direction within the pile head 24. Can be done smoothly. In addition, the pile head metal fitting 30 is set such that the thickness in the axial direction is thicker than the thickness required for strength. When the height of the pile head of the steel pipe pile 20 after being buried (height exposed from the ground) is lower than the dimension set in advance, the pile head fitting 30 is slightly exposed from the inside of the pile head 24 and the height is This is to allow fine adjustment. In addition, when the height of a pile head is higher than the height set beforehand, the steel pipe pile 20 may be cut | disconnected. Incidentally, in the case of a concrete pile, the height of the pile head cannot be adjusted by such cutting, and the merit of using the steel pipe pile 20 is also here.

The adjustment long hole 31 has a lengthwise dimension that is caused by a horizontal displacement predicted when the steel pipe pile 20 is buried (between the axis of the steel pipe pile 20 and the axis of the pedestal 11). Is set to a length that can correspond to the long hole dimension range corresponding to the construction pile diameter . When the actual construction error exceeds the lengthwise dimension of the adjustment elongated hole 31, that is, when the adjustment elongated hole 31 cannot be fully accommodated, the portion that could not be accommodated (the adjustment elongated hole 31 is changed). For the construction error range exceeding), the adjustment loose hole 51 is set to a dimension that can accommodate the same portion, so there is no problem.
