。The pile cap 3 of the present invention is a mortar-shaped concrete pile having a plurality of reinforcing bars 6 and 7 extending directly upward and diagonally upward from the upper surface 5 and having a convex portion 8 formed in the center of the upper surface 5. A hole 10 is formed in the bottom of the cap body 9 to fit loosely into the top of the stake 2, and a gap 11 between the hole 10 and the stake 2 is formed.
In order to inject mortar from the upper side of the pile cap body 9, a mortar injection channel 12 is formed in the pile cap body 9 and opens between the wall surface of the hole 10 and the top surface 5 of the pile cap body. The opening on the top side of the cap body is a mortar injection port 13, and when the pile 2 is inserted into the hole 10, the top surface 5 of the pile cap body is at the same height as the ground 1 and is in contact with the bottom surface of the concrete footing 4. There is.
本考案においては、前記構成の杭キャップ３を工場等て
予め製作しておいて現場に搬入する。In the present invention, the pile cap 3 having the above structure is manufactured in advance at a factory or the like and then transported to the site.

る。Then, the pile cap 3 is placed above the pile 2 and the top of the pile 2 is inserted into the hole 10, so that the pile cap 3 is placed on the top of the pile 2. Next, the recess 14 is filled with earth and sand, etc. After that, from the mortar injection port 13 to the mortar injection channel 12
The pile cap 3 is completely fixed to the pile 2 by injecting mortar and filling the gap 11 with mortar, and finally concrete is poured in the required area including the top surface 5 of the pile cap body to form a concrete footing 4. As a result of the above, the top surface 5 of the pile cap body is brought into contact with the bottom surface of the concrete footing 4, and the concrete footing 4 is
The load of the pile 2 is supported by the pile 2, and the action of the convex portion 8 is used to connect the pile cap body 9 and the concrete footing 4 by the action of the reinforcing bars 6 and 7 to ensure the connection between the two. This ensures that horizontal force can be transmitted reliably.
