JOINT MEMBER FOR CONSTRUCTION BLOCK, AND CONSTRUCTION BLOCK

摘要

PROBLEM TO BE SOLVED: To provide a joint member for a construction block used in joint installation work in which the construction blocks are connected by engaging both ends of a fixing pin to an engaging hole on an edge surface of the adjacent construction block, the fixing pin being inserted into a fitting hole of a joint plate, and the joint member allowing the construction blocks to be connected readily with the fixing pin, even when a position and an orientation of the engaging hole deviated due to a dimensional error in the construction block.;SOLUTION: A joint member for a construction block includes a contractible joint plate 20 inserted between edge surfaces of the adjacent construction blocks, and a fixing pin 30 inserted into a fitting hole 21 of the joint plate and having both ends engaged with an engaging hole on an edge surface of the construction block. The fitting hole 21 of the joint plate is formed such that when the fixing pin 30 is fitted, a peripheral surface of the fitting hole 21 comes into contact with an outer peripheral surface of the fixing pin 30 at a plurality of locations 21a in a peripheral direction, and a gap 22b is formed between the contacting locations 21a.;SELECTED DRAWING: Figure 4;COPYRIGHT: (C)2016,JPO&INPIT
