BUILT-UP TYPE BURIED BLOCK

PURPOSE:To enable the transportation and storage by separating a top type buried block into a shaft leg and a body and constructing so as to anchor and engage both of them. CONSTITUTION:A coupling rod 8 of a shaft leg 3 is inserted into a through-hole 5 of a body 2 from the lower side thereof. When a step section 7 is brought into contact with the lower end 6 of the body engaging projections 13 are projected to the inside of a recessed section 11 from relief groove sections 12, so that in the case the shaft leg is turned 90 deg., each of the engaging projections 13 is anchored. At that time, longitudinal grooves 19 of sides of tips of the engaging projections 13 is opposed to longitudinal grooves 18 of the body 2 side, so that the rotation of the shaft leg 3 is prevented by inserting coupling members 9 into both longitudinal grooves 18 and 19, and an anchoring state is kept. Assembly is made at an execution field, and in the case of transportation and storage, the shaft leg 3 and body 2 remain unbuilt-up.
