詰まり具合が必ずしもよくないことになる。Conventionally, hemispherical dome-shaped concrete blocks as shown in Figure 2 have been used for fish reefs, wave dissipation, and foot protection. Blocks basically belong to large blocks, with a diameter of approximately 1 meter, but recently there has been a demand for larger blocks. In the conventional method, when molding this, an inner mold and an outer mold that are almost similar to the block to be molded are prepared, and the distance between these is equal to the wall thickness of the block to be molded. It was a tight fit. When forming in this way, concrete is normally poured into the space between the inner and outer formwork through a hole made at the top of the dome shape, which gives the formwork a so-called swee-like shape. Because of this, the concrete is dispersed and the clogging condition of the concrete is not necessarily good.

ことを目的とするものである。Therefore, this invention consists of an inner mold formed into a hemispherical dome shape, and an outer mold arranged around the outer periphery of this inner mold so as to maintain a gap corresponding to the wall thickness of the concrete block to be molded. In molded concrete block molding, the formwork is stood up in the shape of a bowl, and concrete is poured from the wide side to the narrow side between the outer mold and the upper edge of the inner mold. To provide a method of pouring concrete when forming a hemispherical dome type concrete block, which improves the clogging of the concrete together with the concrete's own weight, and as a result, the surface of the block to be formed can be beautifully finished. This is the purpose.

コンクリートは凝縮せられることになる。Next, an embodiment of the concrete pouring method for forming a hemispherical dome type concrete block according to the present invention will be described with reference to the drawings. 1 is an inner mold formed into a hemispherical dome shape, and 2 is an inner mold formed in a hemispherical dome shape. The outer mold is placed so as to cover the outer periphery of the concrete block 1 with a gap equal to the thickness of the concrete block to be molded. As shown in the figure, the inner mold 1 and the outer mold 2 are erected in the shape of a bowl. This creates a gap between the inner and outer formworks 1 and 2, so concrete is poured from this area. Then, the concrete flows downward along the inner surface of the outer mold 2 and gradually accumulates. During this process, the concrete that has already accumulated below will be condensed by the concrete being pumped in from above.

という効果を有するのである。As mentioned above, according to the concrete injection force method when forming a hemispherical 1-m type concrete block according to the present invention, concrete is poured from the wide side to the narrow side, which improves concrete clogging and improves the forming process. At times, air bubbles are removed from the concrete layer, and the surface finish of the molded product is also improved.
