<p>The present invention relates to a pin, a wedge and a pin having an integrally formed wedge for joining blocks, and more particularly, to a pin, a wedge and a pin having an integrally formed wedge for joining blocks, wherein one end of the pin is press-fitted into a hole of a block and the other end thereof inserted into a hole of another block is ruptured by the wedge and then fixed into the hole of the other block so that the two blocks can be easily joined. The pin for joining blocks according to the present invention is cylindrical and comprises a taper portion which is formed at one end portion of the pin, a press-fitting portion which extends with a constant diameter by a predetermined length from the taper portion, and a wedge receiving portion which a diameter smaller than that of the press-fitting portion, is formed with a plurality of rupturing grooves having a constant depth in an axial direction from the other end of the pin at an outer peripheral surface thereof, and is formed with a wedge receiving hole having a predetermined depth in the axial direction from the other end. The wedge of the present invention comprises a wedge portion which is formed to take the shape of a truncated cone having a maximum diameter larger than a diameter of a wedge receiving hole of the pin and a minimum diameter smaller than the diameter of the wedge receiving hole. Further, the pin having an integrally formed wedge for joining blocks according to the present invention is characterized in that the pin is integrally formed with the wedge.</p> |
