摘要： PROBLEM TO BE SOLVED: To provide a joint part of a pile and an H-shaped column easily absorbing a construction error, reducing pile head bending moment and semi-rigidly joinable.
SOLUTION: Bar-like hardware 5 extending in the axial direction of the H-shaped column 2 is embedded in a concrete cross section from the head of the pile 1 to a column base part of the H-shaped column 2. A column base part web 2a part of the H-shaped column 2 is provided with a cutout part 4 for avoiding interference with the bar-like hardware 5. Steel plates 6 for connecting flanges 2b to each other are mounted so that the upper ends come to a height above the upper end of the cutout part 4 to compensate cross-sectional defect by the cutout part 4. Concrete 7 is placed inside surrounded by the flanges 2b and the steel plates 6. A steel foundation beam 11 in a strong axis direction is joined to the flange 2b of the column base part of the H-shaped column 2, and a steel foundation beam 12 in a weak axis direction is joined to the steel plate 6. Against large external force, rotational deformation occurs to a pile head joint surface by the slip-out deformation of the bar-like hardware 5 and the compressive deformation of pile head concrete to obtain a semi-rigidly joined state.

摘要： PROBLEM TO BE SOLVED: To provide a pile-head junction structure, the cost of which is reduced and which easily absorbs an error on the execution of works and can decrease a pile-head bending moment. SOLUTION: The junction structure joins a pile 1 and a column 2 having footing beams 3 made of steel joined a column base section, and a rod-shaped metallic material 6 extended in the axial direction of the pile 1 and the column 2 is disposed in concrete 7 constituting the central section of a concrete cross section constituting the pile head section of the pile 1 and the column base section of the column 2. When the bending moment at a specified value or more works, a pile-head joining section is brought to a semi-fixed state by the extraction of the rod-shaped metallic material 6, the bending moment of the pile head section is reduced and the pile-head joining section can be formed in a simple structure at the low cost. The rod-shaped metallic material can be installed in the column 2 even to the error on the execution of works in the certain extent of the pile 1, and the error on the execution of works is absorbed easily in the horizontal direction. A base plate 4 at the lower end of the column 2 is used in common with a diaphragm for joining the footing beam and mandays for a junction working can be reduced, and the quantity of excavated soil can be decreased because the height of a footing-beam 3 section is lowered.

摘要： PROBLEM TO BE SOLVED: To provide a pile-head joint structure, the cost of which is reduced and in which an error on the execution of works is absorbed easily and the bending moment of a pile head can be lowered.
SOLUTION: In the joint structure of a pile 1 and a column 2 in which a footing beam 3 is joined with a column base section, rod-shaped metallic materials 6 such as a steel bar extended in the axial direction of the pile 1 and the column 2 are disposed at the central section of a concrete cross section constituting the pile head section of the pile 1 and in concrete 7 constituting the column base section of the column 2. When bending moment of a prescribed value or more works, a pile-head joining section is brought to a half-fixed state by the slipping-out of the metallic materials 6, the bending moment of the pile head section is lowered and the pile-head joining section can be formed in a simple and inexpensive structure. Since the structure in which the metallic materials 6 are arranged at the sectional central section of the pile is formed, the metallic materials 6 can be installed into the column 2 even against the error on the execution of works in a certain extent of the pile 1, and the error on the execution of works in the horizontal direction is absorbed easily.

摘要： PROBLEM TO BE SOLVED: To stabilize the restoring force of a pile head part by connecting, in nearly pin state, the pile head part to a foundation structure with an inexpensive means irrespective of such conditions as the number of layers of an upper structure, type of pile, N-value of a ground, and metal material.

For the metal bar-like body 1 including anchor bolts 4 and reinforcements 8 connected to the head part of the pile 6 and the foundation structure 7, the bending rigidity of the metal bar-like body 1 is evaluated as the rotating rigidity of the pile head. An axial compressive strength necessary for the metal bar-like body 1 when the head part of the pile 6 is brought into a stress state near that of the pin is specified against a yield axial force or cross section dimensions.
