Abstract
Description
【発明の詳細な説明】 （産業上の利用分野） 本発明は杭基礎に係るものである。[Detailed description of the invention] (Industrial application field) The present invention relates to a pile foundation.
（従来の技術）
従来、基礎梁の２７１７間に配置された杭の杭頭接合部
は、一定の固定度を有するような仕様の場合でも、軸力
は伝達するが、曲げモーメント及び剪断力は伝達しない
ローラージヨイントと仮定スることがあった。(Prior art) Conventionally, the pile head joints of piles placed between 2717 of foundation beams transmit axial force even if they are designed to have a certain degree of fixation, but bending moments and shear forces are There were times when I assumed it was a roller joint that did not transmit.

な構造の出現が要望されてＸ４する。(Problems to be Solved by the Invention) Although the pile head joint has a certain degree of fixation, the design in which the head of the pile is assumed to be a roller does not suit the actual situation, and the pile head joint has a certain degree of fixation. There is a demand for a concrete structure in which the joint part is a roller mechanism, so X4.

This relates to a pile foundation characterized by being interposed with.

をローラ−ジヨイントとすることができる。(Function) and (Effects of the Invention) In the present invention, a partition material is interposed between the trap, the pillow head and the footing lower surface, and the pillow head and the footing are structurally insulated by the partition material. There is no or very little embedding of the head of the pillow into the 7-chin, and almost no bending moment or shearing force of the pile is transmitted from the side of the pile. Therefore, according to the present invention, the pile can be easily constructed with a simple structure. The head joint can be a roller joint.
（実施例） 以下本発明を図示の実施例について説明する。(Example) The present invention will be described below with reference to the illustrated embodiments.

チング（３）と杭（１）とを前記仕切板（２）を介して
構造的に絶縁する。(1) is a pile, and a partition plate (2) made of iron plate, fluororesin plate, etc. is mounted on the head of the pile, and the footing (3) constructed on the pile head and the pile (1) are separated by the partition plate (2). Structurally insulated via plate (2).
図中（４）は捨コンクリート、（５）は敷砂利である。In the figure, (4) is concrete, and (5) is gravel.
図示の実施例によれば前記したようＫ、杭（１）の枕頭

チング（３）とが構造的に絶縁されることによって、杭
頭接合部がローラージヨイントに構成される。According to the illustrated embodiment, as described above, the pile (1) and the footing (3) are structurally insulated by the partition plate (2) mounted on the head of the pile (1). , the pile cap joint is configured as a roller joint.
また杭（１）のフーチング（３）Ｋ対する埋込量は０ま
たは小さなものとして、杭（１）の側面からの杭の曲げ
モーメント及び剪断力が殆んど伝達されることがなく、
ローラージヨイントが確実に構成される。In addition, the amount of embedding of the pile (1) into the footing (3) K is 0 or small, so that almost no bending moment and shear force of the pile is transmitted from the side of the pile (1).
The roller joint is reliably configured.
