Title:
METHOD FOR LAYING PLATE-LIKE BODY
Document Type and Number:
Japanese Patent JP2808438
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce the distortion of a plate-like body in its lifted condition and the diameter of a lifting component by locking an eyebolt attached to the lifting component in a plate-like anchor component to lift the same horizontally.
SOLUTION: An eyebolt 18 attached to a lifting component is locked in an anchor component 11. The eyebolt 18 has a ring-like hook part 18c in the upper part of a screw part 18b having a thumbscrew 18a, and the lower part of the screw part 18b is formed to be elliptic in section. The screw part 18b is inserted into the circular part of a loading hole 13, then slid along a thin longitudinal part, rotated by about 90° by an expansion diameter part and locked therein. The thumbscrew 18a is lightly fastened in this condition to lock the eyebolt 18 in the anchor component 11. Since lifting by the eyebolt 18 is multiple in points coinciding with the pitch of the anchor component 11, an asphalt mat is prevented from being distorted at a high temperature and the occurrence of cracks at a low temperature is prevented.
