Claims

[Scope of utility model registration request]

A part of the core body 3 for making the hollow concrete mold is divided in the longitudinal direction, and has a connecting member 7 inserted into the divided part, and the core body is expanded and contracted by the expansion/contraction means 6 disposed in the longitudinal direction within the core body. and a connecting member are connected by respective links or connecting plates 29, and the core body and the connecting member are connected within a plane perpendicular to the longitudinal direction of the core body, and rotation of the expansion and contraction means. This is a formwork for a hollow concrete block in which the core body shrinks and expands in conjunction with the movement of connecting members.The outer frame 1 and the bottom of the formwork are connected by a bendable flexible plate 20, and the outer frame is Hollow concrete block formwork made of flexible plates that tilt outward and open due to elasticity centered on the longitudinal direction.
