において基本構成部材として使用されている。(Prior art) A top-shaped block balances the weight of the block itself, the vertical load it receives, and the total force of the ground reaction force and frictional resistance generated in the body and pivot legs, so that the block can be leveled without uneven settlement. It exerts the bearing capacity of the soil, and is used as a basic component in various ground stabilization and foundation reinforcement construction methods.

あつた。(Problem to be solved by the invention) Because of its unique shape in which a small-diameter pivot leg is protruded from the wide-diameter tip of the body, the top-shaped block can be made of not only unreinforced concrete but also reinforced concrete. However, during demolding, transportation to a curing yard, temporary storage, or installation, large stress is likely to be applied to the connection root between the body and the pivot leg, which can cause cracks to form at the connection root, or in severe cases. In some cases, the pivot leg broke.

体的に固着される。(Function) The outer cylindrical body 6 provided with the through hole 6a or the notch 9 is inserted in advance into a concrete molding formwork together with the hanging tool 5 which also serves as a reinforcing bar, and is held at a predetermined position, and is then held in a predetermined position within the formwork. Concrete is poured into the area. Due to the concrete entering the through hole 6a or the notch 9 and hardening, the outer cylindrical body 6 is integrally fixed to the block-shaped block 4.

の取扱いが安全かつ簡単に行なえることになる。(Effects of the Invention) As described above, in the top-shaped block of the present invention, since the body 2 and the pivot leg 3 are entirely covered with the outer cylinder 6,
There will be no cracks at the connection between the body 2 and the pivot leg 3, or breakage of the pivot leg 3, during demolding, transportation, installation, etc., and the frame-shaped block can be handled safely and securely during production, transportation, and installation. It will be easy to do.
