［産業上の利用分野］
本発明は、扁平上盤の下部に円錐又は角錐型胴
体を設け、該胴体２の下部中心に円柱型又は角柱

る。Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a top having a conical or pyramidal body provided at the lower part of a flat upper board, and a cylindrical or prismatic pivot leg provided at the center of the lower part of the body 2. It concerns type blocks.
［従来の技術］

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, thereby preventing uneven settlement. It exerts horizontal ground bearing capacity and is used as a basic component in various ground stabilization and foundation reinforcement construction methods.
［発明が解決しようとする課題］

あつた。[Problems to be Solved by the Invention] Because of the unique shape of the top-shaped block, in which a small-diameter pivot leg is protruded from the tip of a wide-diameter body, it can be made of not only unreinforced concrete but also reinforced concrete. However, during demolding, transportation to a curing yard, temporary storage, or installation, a large amount of stress is likely to be applied to the connection base between the body and the shaft leg, which can cause cracks to form at the connection base, or in severe cases, cause the shaft to fail. Sometimes the legs were broken.

ツクを提供することである。 Therefore, an object of the present invention is to cover the connecting part between the body part and the shaft leg part with an outer cylinder so that it can withstand external forces from multiple directions, and to prevent this reinforcing outer cylinder from slipping off from the connecting part. The object of the present invention is to provide a top-shaped block that is fixedly integrated with a connecting part.

たものである。[Means for Solving the Problems] Hereinafter, it will be explained using the reference numerals in the attached drawings. The top-shaped block of the present invention has a conical or pyramidal body 2 provided at the lower part of a flat upper plate 1, and the shape of the body 2. A cylindrical or prismatic shaft leg 3 is provided at the center of the lower part, and the body 2
The connecting part 5 between the lower part of the shaft leg 3 and the upper part of the shaft leg 3 is connected to the outer cylindrical body 6.
The outer cylindrical body 6 is coated with concrete, and concrete is poured into the plurality of through holes 6a provided in the outer cylinder 6 during molding and hardened.

したり、軸脚３が折損することがない。[Function] In this top-shaped block, the connecting part between the body 2 and the pivot leg 3 is covered with the outer cylindrical body 6, so even if external forces are applied from multiple directions during demolding, transportation, installation, etc. It can withstand the external force, and the connecting portion will not crack or the shaft leg 3 will not break.

are provided in a substantially uniform distribution over the entire outer cylinder body 6. This outer cylindrical body 6 is previously inserted into a concrete molding form together with the hanger 7 and held in a predetermined position, and then concrete is poured into the form. The outer cylindrical body 6 is integrally fixed to the frame-shaped block 4 because of the concrete that has entered the through hole 6a and hardened.

The material of the outer cylindrical body 6 may be any material, such as metal, plastic, ceramic, etc., as long as it can prevent the top-shaped block 4 from cracking or breaking due to external force.

る。[Effects of the Invention] As described above, in the top-shaped block of the present invention, a plurality of through holes 6a are provided in the reinforcing outer cylindrical body 6 covering the connecting portion, and the through-holes 6a are formed during molding of the top-shaped block. As the concrete enters and hardens inside 6a, the outer cylindrical body 6 is firmly fixed and integrated with the top-shaped block, and the outer cylindrical body 6 does not slip off from the connecting part and remains firmly in its original position in close contact with the connecting part. This ensures that the desired reinforcing action is achieved.
