DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the illustrated embodiment. FIG. 1 is a partial structural view of the first embodiment, and a reinforcing member 1 can be used for a so-called solid foundation based on the entire underfloor of a building. The reinforcing member 1 is composed of a number of reinforcing bars 2 composed of a bar net with ribs and a number of flat steel plates 3 of long strip shape.
, And are separated from the discarded concrete surface via a number of blocks 4 made of wood pieces, concrete pieces, and the like. The reinforcement 1 of this embodiment is
For example, it corresponds to the foundation of a wooden house of several tens of tsubo, and the outer diameter of the reinforcing bar 2 is set to a normal 13 mm. The material of the flat steel 3 is a general steel material, and its strength level is 300 to 100.
0 N / mm ² .

As shown in the partial perspective view of FIG. 2, the thickness t, width W, and length L of the flat steel 3 are, for example, 3 mm and 65 m, respectively.
m, 1080 mm, and in this case, 178 m ² (5
Although the house is 4 tsubo, about 420 sheets of flat steel 3 are used for the reinforcing body 1. Six insertion holes 3a through which the reinforcing bar 2 is inserted are formed in the flat steel 3 at equal intervals of 200 mm, and the distance between the end surface and the insertion hole 3a located near the end is 40 mm. These insertion holes 3a are circular, and the inner diameter thereof is larger than the outer diameter of the reinforcing bar 2, for example, 1 mm.
5 mm. The flat steel 3 is, for example, 5500 m
It can be formed by cutting a standard length of m into five equal parts by cutting, and the insertion hole 3a can be formed by punching.

When assembling the reinforcing member 1, six reinforcing bars 2 adjacent to each other are inserted into the six insertion holes 3 a of one flat bar 3, and all the flat bars 3 are connected to the reinforcing bars 2. Assemble to. The interval between the flat bars 3 can be arbitrarily adjusted at the construction site. At this time, the common reinforcing bar 2 is inserted into the insertion hole 3a located at the joint between the continuous flat bars 3, and the flat bars 3 are connected in a link shape. Then, all the reinforcing bars 2 and flat bars 3 are arranged at predetermined positions, and the assembled substantially lattice-shaped reinforcing body 1 is placed on a large number of blocks 4 so that ready-mixed concrete can be easily poured.

As shown in FIG. 3, when the ready-mixed concrete C is poured into the assembled reinforcing body 1, the ready-mixed concrete C flows smoothly to all corners within the range of the formwork. And flat steel 3
The inner diameter of the through hole 3a is larger than the outer diameter of the reinforcing bar 2, so that the flat steel 3 is inclined with respect to the direction of gravity by the action of the ready-mixed concrete C into which the flat steel 3 flows.

Further, when the fresh concrete C is cast,
By inclining the flat steel 3 with respect to the direction of gravity, the flat steel 3 can bear loads in the vertical direction and the horizontal direction, and the earthquake resistance can be improved. In addition, when coping with underground beams, buried pipes, etc., a reinforcing step was conventionally required after providing a cut, but the reinforcing step is not required, and it can easily cope with underground beams, buried pipes, etc. .

In the first embodiment, the method of assembling the reinforcing member 1 for a wooden house of about 178 square meters has been described, but it goes without saying that this method can be applied to buildings of different scales. In addition, the thickness t, width W, and length L of the flat steel 3 are set to 3 mm, 65 mm, and 1080 mm, respectively.
, But each other arbitrary size, for example, 4.5 m
m, 44 mm, or 1080 mm, and preferably has an appropriate size corresponding to the scale of the building.

One flat steel 3 has six insertion holes 3a.
Are formed at equal intervals, but it goes without saying that the intervals can be appropriately increased or decreased according to the arrangement of the reinforcing bars 2. Further, the strength can be enhanced by inserting a plurality of rebars 2 into the joint portion between the flat bars 3. Furthermore, as shown in FIG. 4, if two adjacent through holes 3 a and 3 b are formed in flat steel 3 ′ having the same size as the above flat steel 3, the interval between the reinforcing bars 2 can be adjusted. Become.

Further, in FIG. 2, by increasing the vertical width of the flat steel 3 and providing the insertion holes 3a also in the vertical direction, the reinforcing steel bar 2 can be installed in multiple levels.

As described above, in the embodiment, the reinforcing body 1 can be completed by inserting the reinforcing bar 2 into the insertion hole 3a of the flat steel 3, so that the crossing portion between the reinforcing bars 2 can be tied up with a wire as in the related art. Alternatively, welding is not required. Therefore, the time required for assembling the reinforcing body 1 and the cost for assembling the reinforcing body 1 can be significantly reduced without requiring a skilled reinforcing bar.

FIG. 5 is a partial configuration diagram of the second embodiment.
The case where the reinforcing body 11 is used for a pillar of a building is shown. The reinforcing body 11 has four first flat bars 12 erected in the vertical direction at positions corresponding to the four corners of the column, and a fourth flat bar 12 in the middle between the adjacent first flat bars 12. 2 and a plurality of rebars 1 horizontally inserted into the insertion holes 12a and 13a of the first and second flat bars 12 and 13.
And 4.

The intersection angle between the main surface of the first flat bar 12 and the longitudinal direction of the reinforcing bar 14 is 45 °, and the intersection angle between the main surface of the second flat bar 13 and the longitudinal direction of the reinforcing bar 14 is 90 °. ing.
The insertion holes 12a and 13a of the flat bars 12 and 13 are formed in an oval shape, so that the reinforcing bars 14 can be received from the inclined direction with respect to the flat bars 12 and 13.

In the second embodiment as well, the reinforcement 11 can be completed only by inserting the reinforcing bar 14 into the insertion holes 12a and 13a of the flat bars 12 and 13, so that the same effect as in the first embodiment can be obtained. .

In the first and second embodiments described above, the use of the flat bars 3, 12, and 13 has been described.
Sheet steel such as a steel sheet cut into a slit, an angle steel sheet, and an L-shaped steel sheet can also be used.

[0021]

As described above, the concrete reinforcing body and the method of assembling the same according to the present invention merely insert the steel bars into the insertion holes formed in the steel plate, so that the steel bars are not tied together as in the prior art. It is not necessary to perform welding, and even a worker who is not familiar with the reinforcing member can easily assemble the reinforcing member in a short time.
