It shows a use state, and the beam concrete member 5
A plurality of beam main reinforcing spacers 4 are placed on the groove bottom plate 6, beam main reinforcing bars 12 are inserted between adjacent U-shaped spacers 2, and vertical arms 11 of the U-shaped spacers 2 at both ends.
The main beam 12 is also inserted between the grooved side plates 14 on both sides of the beam concrete member 5, and the beam is placed on the vertical arm 11 on the side of the grooved side plate 14 in the U-shaped spacer 2 at both ends. The lower part of the vertical pipe 9 in the main reinforcement support 10 is fitted, and the vertical support rod 17 is arranged so as to be close to the groove side plate 14, and extends over the beam main reinforcement mounting portion 7 arranged in the longitudinal direction of the groove side plate 14. After the upper beam main reinforcement 12 is placed and all the beam main reinforcements 12 are arranged in the beam concrete member 5, concrete is poured into the beam concrete member 5.

In practicing the present invention, the number of U-shaped spacers 2 and the number of beam main bar supports 10 may be increased or decreased.

[0010]

According to the present invention, the main beam spacer of the present invention has a horizontal band.
The upper surface of the Jo metal plate 1, a plurality of U-shaped scan you open upward
Place pacer 2 at a distance approximately equal to the beam main bar diameter.
The U-shaped spacers 2 are fixed to the strip-shaped metal plate 1 in a row.
Between the adjacent U-shaped spacers 2
The beam main reinforcing spacer 4 is formed by providing the gap 3 and the beam main reinforcing spacer 4 is formed.
Reinforcement spacer 4 is grooved bottom plate of grooved beam concrete member 5
6. A beam main bar spacer to be mounted on 6, the beam main bar mounting portion
The upper part of the vertical pipe 9 is fixed to a support fitting 8 having
The vertical tube 9 is formed by a beam supporting member 10 and the beam main bar space is formed.
In the vertical arm 11 of the U-shaped spacer 2 in the sir 4
It is characterized by being inserted. This allows for a simple structure
Using the beam main bar spacers 4, a plurality of beam main bars 12 are
