A wire mesh 2 of m / m is attached by welding, and a pair of parallel reinforcing bars 3 and 4 having a diameter of 4 m / m are parallel to each other along the longitudinal direction of the reinforcing bar frame 1 at an interval of C1 = 100 m / m. Welding is performed at a distance of C2 50 m / m from the reinforcing bar frame 1, and the tips 3a, 4a of the parallel reinforcing bars 3, 4 are spaced from the short side 1b by a distance C3
= 150 m / m protruding to form extension portions 3b, 4b, at positions where a distance C4 = 50 m / m from the short side 1b of the reinforcing bar frame 1 in the extension portions 3b, 4b toward the tips 3a, 3b, A stopper 5 having a diameter of 4 m / m is welded at a distance of 100 m / m from each of the tip portions 3a, 3b of the extension portions 3b, 4b, and an end rod 6 is welded between the tip portions 3a, 3b.

Although not shown other than the above-mentioned concrete beam frame plate, all dimensions are the same except that the interval C1 between the pair of parallel reinforcing bars 3, 4 in the concrete beam frame plate shown in FIG. 1 is changed to 110 m / m. Then, another concrete beam frame plate having the same structure is prepared.

When a concrete beam is constructed on a slope using the frame plate of this embodiment, as shown in FIGS. 2 and 3, main reinforcing bars 11, 12, 13, and 14 are formed on a slope 10 in a grid pattern. And the frame plate of the present invention is arranged so as to surround the main reinforcing bars 11, 12, 13, and 14 from both sides except for the crossing portion 15.

At this time, the extensions 3b and 4b of the parallel reinforcing bars 3 and 4 of two frame plates adjacent to each other on the same line are partially overlapped, and the end bars 3a and 4a of the ends of the parallel reinforcing bars 3 and 4 of one frame plate. 6 against the stoppers 5 of the parallel reinforcing bars 3 and 4 of the other frame plate,
At the same time, the tips 3a, 4 of the parallel reinforcing bars 3, 4 of the other frame plate.
The end rod 6 of a is abutted against the stoppers 5 of the parallel reinforcing bars 3 and 4 of the one frame plate.

Further, the extending portions 3b, 4b of the parallel reinforcing bars 3, 4 of the two frame bodies crossing at right angles are fitted to each other. At this time, the larger one of the distance C1 between the parallel reinforcing bars 3 and 4, that is, 110 m
As shown in FIG. 4, the smaller one of the distances C1, ie, 100 m / m, is inserted as shown in FIG.

In this state, the overlapped portions of the extensions 3b, 4b are tied up 16 and the portions of the stoppers 5 in the extensions 3b, 4b are connected to the main reinforcing bars 11, 12, 13, 1 described above.
4 is tied up 17 while being pressed against.

By performing the binding 17, the distance between each of the main reinforcing bars 11, 12, 13, 14 and the short side 1b of the reinforcing bar frame 1 is reduced from the short side 1b of the extension portions 3b, 4b to the stopper 5. Is equal to the interval C3.

At the same time, the distance L from the main reinforcing bars 11, 13 to 12 and 14 becomes equal to the distance C4 from the stopper 5 to the tips 3a, 3b.

In this way, as shown in FIG. 2, the frame plates of the present invention are combined vertically and horizontally to form beam-like spaces 18, 19,
20 and 21 are formed, and concrete mortar 22 is provided in beam-shaped spaces 18, 19, 20 and 21 of the frame.
Fill.

At this time, the concrete mortar protrudes from the mesh of the wire mesh 2 of the frame plate of the present invention toward the outside 23,
The projection 24 of the concrete mortar is formed there.

The projection 24 of the concrete mortar is finished to a flat surface 25 as shown in FIG. 6 by a trowel (not shown). As a result, the wire mesh 2 and the reinforcing bar frame 1 are buried in the concrete mortar 22.

This iron finishing is performed on all sides of the beam,
After curing, as shown in the cross section of Fig. 7, the main beams 11, 12, 13, and 14 are buried in the center of the cross section of the beam, and concrete beams with the frame plate of the present invention buried on both sides thereof are constructed. Is what you do.

The present invention has been described with reference to the embodiment shown in the drawings. However, the present invention is not limited to this embodiment alone, and the partial structure and dimensions can be changed or the partial structure can be added or added within the scope of the present invention. It is possible to omit and implement. For example, a cut may be made at the center of the stopper 5 and the end rod 6 may be omitted.

[0024]

The present invention is as described above. Therefore, when assembling the above-mentioned conventional frame plate, it is possible to use a conventional binding member such as a core having a special shape and structure, such as a core end or a core tie. Only wires to be used are required, and the workability is extremely good.

Further, since both ends of a pair of parallel reinforcing bars protrude from the reinforcing bar frame to form an extension and a stopper is provided at a predetermined distance from the tip of the extension, a frame plate is used. When arranging the reinforcing bars in the assembled beam frame, the distance between the reinforcing plate and the frame plate of the present invention, which constitutes the frame, is simply determined by the tip of each extension without any special member or skill. And the stoppers can be held at a predetermined interval only by abutting each other.

Further, since it is constructed as described above, the frame plates are combined to form a beam frame mold, and when this frame mold is filled with concrete mortar, the concrete mortar protrudes from the wire mesh portion. By ironing this, it is possible to easily bury the wire mesh, the reinforcing bar frame, the parallel reinforcing bars, and the like in the concrete beam.

Therefore, as in the case of using the conventional formwork, there is no need to separate the frame plate from the concrete beam after curing and to carry it out of the slope to another place. Is extremely good. At the same time, since the frame plate of the present invention is buried on both sides of the concrete beam, the strength of the concrete beam can be increased.
