2. Description of the Related Art Generally, joints of reinforced concrete beams and walls are planned to be jointly planned when there is a large-scale building exceeding the daily concrete casting capacity, when there are relations with existing facilities, or when there is a height difference. It is often necessary to install and cast concrete and to combine old and new concrete. The skeleton concrete designed with an integral structure
Even when a joint is provided, the reinforcing bar must be continuous and penetrate the damping plate of the joint to be integrated with the concrete installed later, as well as a durable joint method. Must.

[0003] Conventionally, the joint forming method of the joint portion has a problem that it lacks workability, economy and durability.
Improvement was required. Next, the conventional construction method will be described with reference to FIGS.
Disadvantages are described for the three types shown in FIG.

[0004] 1. In the first method, as shown in FIGS. 6 and 7, after the ready-mixed concrete 1 reaches the partition and the concrete is hardened to a certain extent, a number of the piers 2 are inserted into the ready-mixed concrete 1 so that the pier does not fall. This is a method in which concrete is poured to the top 3 of the slab while holding the upper part. (Defects) (1) There is no partition bar below the beam main reinforcement 4, and a large amount of ready-mixed concrete flows out of the gap between the bars. (2) The crosspiece is not aligned in a straight line and the joint surface is not uniform (Fig. 7). (3) After the concrete has hardened, the pier will not come off. (4) Since the concrete that has flowed out is a separated concrete with a small amount of coarse aggregate, it must be removed by removing the formwork 5. (5) When the concrete flows out of the partition part, the concrete at the top end 3 of the beam partially sinks 3 ', a cavity is formed at the lower end of the main beam 4 and the adhesive force between the main beam and the concrete is reduced.

[0005] 2. The second method is a method in which the pier 2 is nailed in advance to the beam formwork 5 and the narrow plate 6 is nailed thereto, as shown in FIGS. (Defects) (1) Although the joint surface is relatively accurate, it is difficult to remove the narrow plate 6 because it expands by absorbing the moisture of the concrete. (2) The removed narrow plate 6 generates a large amount of wood chips at the time of removal, which increases the disposal cost. (3) If narrow boards are installed without any gaps to prevent concrete from flowing out, the concrete surface becomes too smooth and lacks integrity.

[0006] 3. In the third method, as shown in FIGS. 10 and 11, a reinforcing bar is assembled in a grid pattern 8 or 8 'in a partition portion, and a wire mesh 9 is attached with the reinforcing bar as a base and driven into concrete. (Defects) (1) When using a wire mesh with overlapping seams, compaction is not performed sufficiently to reduce the flow of ready-mixed concrete at the time of placing concrete, so that a cavity may be formed inside the wire mesh. (2) The surrounding formwork must be dismantled and the wire mesh where the cavities have formed must be removed by gas fusing or the like so that no cavities remain on the joint surface. (3) Since the wire mesh and the base reinforcing bar 8 in the cover thickness portion of the stirrup 10 have poor durability, they must be removed by using gas fusing and hanging together. (4) Since the base reinforcements 8 and 8 'are directly welded to the stirrup 10, an undercut is generated in the stirrup, which causes a reduction in strength due to a cross-sectional defect. (5) Assembly and removal are troublesome and uneconomical.

Next, a partition mold at a fogging portion with respect to the stirrup mold is formed. As shown in FIGS. 1, 3 and 4, the side surface of the beam is adjusted so as to match the space between the beam side formwork 5 and the bridge recess 22 of the guide fitting 20 previously fixed to the stirrups 10 and 10 ′. Insert the insertion piers 28, 28 of the processed dimensions up to the beam bottom form 5 ', and
The nail 29 is hit and fixed at several places on the insertion bar 28 from outside. Next, with regard to the beam bottom, after the concrete is cast, the structural members serving as the partitioning formwork of the cover thickness portions of the reinforcing bars 4, 10, 10 'are left, leaving the side formwork 5 of the beam and the formwork 5' of the bottom. Although it must be removed while standing, the assembled beam 4,
There are 10, 10 ', which are difficult to reach and very difficult work, so they must be easily removed. Therefore, as shown in FIG. 5, the long side of the trapezoidal angle member 30 is fixed to the beam bottom form 5 'with a nail 31 in accordance with the concrete placing side of the insertion beams 28, 28 attached to the side surfaces of the beam, and the guide fitting is provided. A pier 32 having a width to be fitted into the bridge recess 22 of the 20 is processed to a thickness of about half the cover thickness of the stirrups 10 and 10 ′. The entire surface of the rising portion is pressed, and two or more wedges 33 are supported below the rising portion.

Furthermore, if the height of the beam rebar assembled at the joint is all the same size, only the unequal angled bar 30 is sufficient, but this is not possible in field work. For adjustment, a pier to be fitted into the lower part of the stirrups 10, 10 'is required. Since the top end of the beam has low side pressure of concrete, the insertion piers 28, 28 on the side of the beam were raised as shown in FIGS. 1 and 4, and a pier 34 cut to fit the inner dimensions thereof was attached to the top of the stirrup. It is inserted into the recess of the guide fitting 20 and is fastened to the insertion bars 28 on both sides with nails 35. When the beam width is wide and unstable, the crosspiece 34 may be further fixed to the guide fitting unit 25 with a track.
