The present invention relates to a pile connecting device comprising: a lower connection plate which is fastened and fixed to a head part of a lower pile by means of a lower bolt and in which lower protrusions protrude radially from the top surface thereof; an upper connection plate which is fastened and fixed to the tip of an upper pile by means of an upper bolt and in which upper protrusions protrude radially from the bottom surface thereof so as to fit in between the lower protrusions of the lower connection plate; press pads mounted to head portions of the lower bolt and the upper bolt; pinholes formed through one surface or both surfaces of each of the lower protrusions of the lower connection plate and the upper protrusions of the upper connection plate; and horizontal pins coupled to the pinholes, wherein the press pads are pressed by the weight of the upper pile and thereby pressed and fixed to the head portions of the bolts, respectively, and thus prevent the bolts from loosening due to vibration from pile driving. According to the present invention, the centers of the lower and upper piles can be easily aligned by forming the side surface of each of the protrusions of the connection plates to be inclined. Thus, working hours can be shortened and work efficiency improved. Also, since the press pads mounted to the head portions of the bolts that fix the connection plates to the piles are pressed by the weight of the upper pile and thereby pressed and fixed, the bolts can be prevented from loosening due to the driving vibration when driving a connection pile in which the lower pile and the upper pile are connected by the pile connecting device of the present invention. Thus, the present invention has the effect of being able to construct strong pile connections.

La présente invention concerne un dispositif de raccordement de pieux comprenant : une plaque de liaison inférieure qui est accrochée et fixée à une partie de tête d'un pieu inférieur au moyen d'un boulon inférieur et dans laquelle des saillies inférieures font saillie radialement à partir de la surface supérieure de celle-ci ; une plaque de liaison supérieure qui est accrochée et fixée à la pointe d'un pieu supérieur au moyen d'un boulon supérieur et dans laquelle des saillies supérieures font saillie radialement à partir de la surface inférieure de celle-ci de manière à s'ajuster entre les saillies inférieures de la plaque de liaison inférieure ; des tampons de pression montés sur des parties de tête du boulon inférieur et du boulon supérieur ; des trous d'épingle formés à travers une surface ou les deux surfaces de chacune des saillies inférieures de la plaque de liaison inférieure et des saillies supérieures de la plaque de liaison supérieure ; et des broches horizontales couplées aux trous d'épingle, les tampons de pression sont pressés par le poids du pieu supérieur et sont ainsi pressés et fixés aux parties de tête des boulons, respectivement, empêchant ainsi les boulons de se desserrer sous l'effet des vibrations provenant du battage des pieux. Selon la présente invention, les centres des pieux inférieur et supérieur peuvent être facilement alignés en formant la surface latérale de chacune des saillies des plaques de raccordement à incliner. Ainsi, les heures de travail peuvent être raccourcies et l'efficacité du travail améliorée. Les tampons de pression montés sur les parties de tête des boulons fixant les plaques de liaison aux pieux sont pressés par le poids du pieu supérieur et sont ainsi pressés et fixés, les boulons peuvent être empêchés de se desserrer sous l'effet des vibrations d'entraînement lors du battage de pieu de raccordement reliant le pieu inférieur et le pieu supérieur grâce au dispositif de raccordement de pieux selon la présente invention. Ainsi, la présente invention a pour effet de pouvoir construire des raccordements de pieux solides.
