Invention of Claim 1 for solving the said subject is a pile head junction structure for joining the head of a pile to a pile junction part, Comprising: A constriction part is provided in the upper end surface to the said pile. And an insertion hole for inserting the insertion part is formed in the pile joint part, and a turn part is provided in an intermediate part of the insertion hole, and the turn part is formed on the outer surface. pile head joint structure der the injection path is characterized by comprising formed therethrough for injecting a bonding agent to exit is, the invention of claim 2, joining the pile head in pile joints A pile head joining method for projecting an insertion portion having a constricted portion on an upper end surface of the pile, and forming an insertion hole for inserting the insertion portion in the pile joining portion, A note for injecting the bonding agent that is provided in the middle part of the insertion hole and that comes out from the groin part to the outer surface. By penetrating a path and fitting the insertion part into the insertion hole, injecting a bonding agent from the injection path, and filling an annular groove formed by the constricted part and the constricted part, The pile head joining method, wherein the pile head is fixed to the pile joint.

本発明は上記のとおりであって、杭接合部の挿入孔内に杭の挿入部を嵌装後、注入路から接合剤を注入するだけで、杭を杭接合部に確固と固定することができるので、接合作業を容易、迅速且つ低コストにて行うことができ、しかも十分な接合強度が得られる効果がある。   The present invention is as described above, and after the insertion portion of the pile is fitted into the insertion hole of the pile joint portion, the pile can be firmly fixed to the pile joint portion simply by injecting the bonding agent from the injection path. Therefore, it is possible to perform the joining operation easily, quickly and at low cost, and there is an effect that sufficient joining strength can be obtained.

本発明を実施するための最良の形態について、添付図面に依拠して説明する。本発明は杭１を杭接合部４に接合するための構造に関するものであって、杭１の方には、その上端面に挿入部２が突設される。挿入部２の中間には、くびれ部３が周設される。   The best mode for carrying out the present invention will be described with reference to the accompanying drawings. The present invention relates to a structure for joining a pile 1 to a pile joint 4, and the pile 1 is provided with an insertion portion 2 projecting from its upper end surface. A constricted portion 3 is provided in the middle of the insertion portion 2.

杭接合部４は、消波体や梁等に一体に設けられる部分であって、そこには、挿入部２を嵌装するための挿入孔５が形成される。挿入孔５の内周面の中間部には、抉り部６が周設される。この抉り部６は、挿入孔５内に挿入部２を嵌装した際、くびれ部３に対向する。   The pile joint portion 4 is a portion provided integrally with a wave-dissipating body, a beam, or the like, and an insertion hole 5 for fitting the insertion portion 2 is formed there. In the middle portion of the inner peripheral surface of the insertion hole 5, a turn portion 6 is provided around. The bent portion 6 faces the constricted portion 3 when the insertion portion 2 is fitted into the insertion hole 5.

７は、抉り部６から杭接合部４の外側面に抜ける注入路であり、そこから、樹脂モルタル等の接合剤８が注入される。   Reference numeral 7 denotes an injection path that passes from the turning portion 6 to the outer surface of the pile joint portion 4, from which a bonding agent 8 such as resin mortar is injected.

杭１の接合に当っては、その挿入部２を挿入孔５内に挿入した後、注入路７から樹脂モルタル等の接合剤８を注入する。接合剤８は、抉り部１０とくびれ部８ａとで形成される断面ダイヤ形の環状溝を充填し、固化する。かくして、杭１が杭接合部４から抜けることなく、確固と固定される。   In joining the pile 1, the insertion portion 2 is inserted into the insertion hole 5, and then a bonding agent 8 such as resin mortar is injected from the injection path 7. The bonding agent 8 fills and solidifies the annular groove having a diamond shape in cross section formed by the turned portion 10 and the constricted portion 8a. Thus, the pile 1 is firmly fixed without coming out of the pile joint 4.
