PURPOSE: To improve the extruding performance of a sticky material to increase the adhesive performance by providing a perforated cylindrical body provided with a plug at the leading end and opened at the tailing end and forming axially perforated sections having respectively different opening ratios along the longitudinal direction. CONSTITUTION: This device is for connecting and fixing two or more stone structures 10, 12 by combinedly using a curable thixotropic adhesive sticky material 26. The device is constituted of a perforated cylindrical body 32 provided with a solid plug at the leading end 34 and opened at the tailing end 36 and further, provided with axially perforated sections 32a, 32b having respective different opening ratios along the longitudinal direction. The opening ratio in the section 32b is made larger and an impermeable band 44 is provided in a section where the sticky material 26 is not required to be extruded. In this way, the sticky material 26 filled in the cylindrical body 32 inserted in the stone structures 10, 12 can be easily extruded to the radial direction of the cylindrical body 32 even when the stuffing force by a stuffing means 42 is weak and hence, the adhesive performance can be improved. |
