Description of the Related Art In general, reinforced concrete foundations are supported by supporting metal fittings after geotechnical construction work, formwork is temporarily installed on both sides of the rebar, and ready-mixed concrete is placed between the formwork, It is constructed by curing and deframing this. In this case, the constructed reinforced concrete foundation has increased tenacity to resist external forces due to the reinforcing bars embedded inside, and the durability is improved, but this reinforcing bar is not located in the center of the inside and the concrete covering thickness is not uniform. Then, its durability will be reduced. Therefore, before pouring ready-mixed concrete, it is important to accurately position the reinforcing bar in the center between the molds in advance. If there is a positional deviation, it will be necessary to interpose a splint or the like between the form and the reinforcing bar to correct the positional deviation.

Reinforcing bar A (upper horizontal bar A ') is fitted into and is attached so that the plate surface is orthogonal to the longitudinal direction, and a plurality of these are attached while leaving an interval. In such an attachment, the reinforcing bar spacer 1 attached to the reinforcing bar A (upper horizontal bar A ') on the inner surface of each form B
By abutting the outer peripheral edge of, the space for pouring ready-mixed concrete between the molds B can be secured, and the reinforcing bar A can be positioned at the center thereof. The plurality of openings 5c have a role of not obstructing the flow of the reinforcing bar A in the longitudinal direction when the fresh concrete is poured between the molds B.

However, the effect is not as high as expected, and there is a problem that the surroundings of the fresh concrete are obstructed. Further, since the plurality of openings 5c are provided, a large number of voids are generated inside the fresh concrete, which causes a problem that durability of the reinforced concrete foundation after hardening is reduced.
