【0027】
▲5▼ 製品の開口部の形状を細長くし、ここより鉄筋を露出さしているので大型で質量が大きい製品でも結束箇所が少なくて多少のカーブにも容易に施工出来る。
【0028】
▲6▼ どんな製品でも開口部よりの2本の鉄筋の隣接鉄筋の間の連結なので従来の様に3又は4箇所よりの鉄線結束又はフック鉄筋の連結方法でないので多少の地盤の凹凸や施工ズレが生じたとしても施工が容易である。
【0029】
加えて、図3の様に凸部に横細長の小魚貝類貫通孔を設けた魚貝類生息可能なる擬石凸部5を空洞とし、連結部の開口部よりの比較的大きい魚貝類貫通孔4と空洞としても、この開口部1の露出鉄筋B.Bやガイド可能連結金具C−Nにより大型魚(ナマズ、雷魚、ブラックバス等)の入る事の出来ない小魚貝類生息出来る水中魚床の根固めブロックも提供出来るものである。

[0012]
(4) Even if there is a product construction error, even if it has a slight curve, it should be a subject that can be easily connected, and at the same time, it should be possible to plant on land and at the same time consider the existence of small fish and shellfish in underwater use. .
[0013]
[Means for Solving the Problems]
The invention of this application is not to construct a connecting part by inclining at the corner of the block like a conventional product, but to provide a plurality of openings on the side wall of the block, and when the construction site has a curve, Adjust the length of the opening to expose the reinforcing bar parallel to the side of the opening, guide the reinforcing bar of the adjacent block, and create a variety of connection fittings according to local use conditions and connection (binding) strength. Means that can be used.
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
{Circle around (1)} It is desirable that the exposed rebar of the present invention can be used not only for connecting and binding after construction, but also as a safe product suspender for demolding during production, factory stock, transportation, and construction, and is inexpensive.
[0015]
(2) Long and large products of 1000 mm x 2000 mm, weight of about 3000 kg / piece-5000 kg / piece and products of at least 1000 mm x 1000 mm weight of about 400 kg / piece-500 kg / piece Something is desirable.
[0016]
(3) It is desirable that a wide variety of metal fittings can be selected and used according to the connection strength depending on the local water quality, flow velocity, service life, product size and weight, and the like.
