In addition, when it is not necessary to temporarily hold down the pair of seismic reinforcement reinforcement molds provided along the seismic reinforcement frame on the upper side or the side part from the lower side or the lateral direction, the above-described seismic reinforcement mold support bracket 1 is described above. As such, the mold retainers 17a and 17b may be omitted.

  Next, a usage example of the seismic reinforcement form-supporting metal fitting 1 of the first embodiment will be described.

  6 (a) and 6 (b) are a front view and a plan view, respectively, showing an example of use of the seismic reinforcement formwork support bracket 1 of the first embodiment.

  As shown in FIG. 6 (a), for example, anchor bolts 91 are implanted on each inner surface of the opening portion of the existing structure 90 made of reinforced concrete to be seismically reinforced, and a large number of web portions facing the inner surface of the opening portion are provided. A seismic reinforcement frame 93 made of a substantially frame-shaped H-shaped steel or the like in which stud bolts 92 are implanted is installed.

  Next, with respect to the flanges 93a and 93b on the outer surface on both sides of the seismic reinforcement frame 93, a gap (space) between the seismic reinforcement frame 93 and the inner surface of the opening of the existing structure 90 is located at the peripheral edge side. The seismic reinforcement molds 94a and 94b are arranged so as to cover the seismic reinforcement molds 94a and 94b, and the first fixed vertical member 12 and the movable vertical member of the seismic reinforcement mold support 1 are placed on both sides of the seismic reinforcement molds 94a and 94b. 13 so as to be sandwiched from the outside by 13. And normally, as shown in FIG.6 (b), the plurality is installed in the longitudinal direction of the earthquake-proof reinforcement frame 93 for every predetermined space | interval.

  It should be noted that the seismic reinforcement frames 94a and 94b are formed on the flanges 93a and 93b on the outer peripheral surfaces of the seismic reinforcement frame 93 so as to close the gap between the seismic reinforcement frame 93 and the inner surface of the opening of the existing structure 90. The reason why the space (height) α is arranged is that the surface of the existing structure 90 usually has unevenness such as unevenness.

  Also, the seismic reinforcement frame 93 is provided with a space (height) β by partially or partially missing the upper and lower sides of the flange portion 93b on one side of the periphery of the seismic reinforcement frame 93. This is because concrete such as mortar is injected from this space (height) β so as to close a gap (space) between the opening portion inner surface of the existing structure 90. Of course, a reinforcing bar (not shown) such as a spiral bar may be inserted into this gap (space) in order to further strengthen the seismic reinforcement.

  Then, both sides of the seismic reinforcement molds 94a and 94b are arranged so as to be sandwiched from the outside by the first fixed vertical member 12 and the movable vertical member 13 of the seismic reinforcement mold support 1 of the first embodiment. Later, by rotating the adjustment bolt 15 and moving it back and forth with respect to the second fixed vertical member 14, as shown in FIGS. 6A and 6B, the movable vertical member 13 is oriented in the direction of the seismic reinforcement form 94b. Then, the first fixed vertical member 12 and the movable vertical member 13 sandwich and temporarily hold the seismic reinforcement molds 94a and 94b from both sides.

  Here, when the pair of seismic reinforcement reinforcing frames 94a and 94b provided along the upper and side seismic reinforcing frames 93 are temporarily pressed from below or from the side, the seismic reinforcement reinforcing frame support metal fitting 1 is In order not to drop, the temporary fixing bolt 16 is temporarily fixed to the flange 93a on the other end side of the seismic reinforcement frame 93 such as H-shaped steel.

The height is adjusted and the mold retainers 17a and 17b are fixed to the first fixed vertical member 12 and the movable vertical member 13 with screws, bolts, or the like, respectively. As a result, the pair of seismic reinforcement reinforcing frames 94a and 94b provided along the seismic reinforcing frame 93 on the upper side or the side are temporarily mounted from below or from the side by the seismic reinforcing form support bracket 1 of the first embodiment. In the case of pressing, it is possible to prevent the seismic reinforcement formwork 94a, 94b and the like from falling.

  Therefore, according to the seismic reinforcement mold support 1 of the first embodiment, the main material 11 and the first fixed vertical material 12 that is fixed to one end side of the main material 11 and extends in a direction perpendicular to the main material 11. And a movable vertical member 13 that is slidably attached to the main member 11 and extends in a direction perpendicular to the main member, and a second fixed vertical that is fixed to the other end of the main member 11 and extends in a direction perpendicular to the main member 11. While being rotatably attached to the material 14 and the second fixed vertical material 14, the tip is rotatably supported by the movable vertical material 13, and the amount of slide of the movable vertical material 13 is determined by rotating, and an arbitrary slide Since the adjustment bolt 15 that stops the movable vertical member 13 by the amount is provided, the pair of the earthquake-proof reinforcement frames 94a and 94b can be securely attached to the earthquake-proof reinforcement frame 93 only by adjusting and tightening the adjustment bolt 15 at one place. To support Possible and it can improve the workability and workability in attaching seismic reinforcement formwork 94a, a 94b.

  In addition, in the seismic reinforcement mold support 1 of the first embodiment, a temporary fixing bolt 16 for temporarily fixing the support metal 1 to the seismic reinforcement frame 93 is further provided inside the main material 11. Therefore, for example, when temporarily holding a pair of seismic reinforcement molds 94a and 94b provided along the upper and side seismic reinforcement frames 93 from below or from the side, this seismic reinforcement mold support bracket 1 can be temporarily fixed to the flange 93a of the earthquake-proof reinforcement frame 93 by the temporary fixing bolt 16 so that the first drop does not fall.

  Moreover, in the seismic reinforcement form support metal fitting 1 of the first embodiment, the first fixed vertical member 12 and the movable vertical member 13 are further provided with inner surfaces of the first fixed vertical member 12 or the movable vertical member 13, respectively. A mold retainer 17a that protrudes further inward and hits the ends of a pair of seismic reinforcement molds 94a and 94b provided along the flange part 93b of the seismic reinforcement frame 93, and holds the seismic reinforcement molds 94a and 94b. 17b, for example, when a pair of seismic reinforcement molds 94a, 94b provided along the upper and side seismic reinforcement frames 93 are temporarily pressed from below or laterally, the seismic reinforcement is provided. It can prevent that the formwork 94a, 94b falls.

  Further, in the seismic reinforcement form support bracket 1 of the first embodiment, the first fixed vertical member 12 and the movable vertical member 13 are respectively set in the longitudinal direction of the first fixed vertical member 12 and the movable vertical member 13. Since the plurality of steps of the mold retainer mounting holes 12a1 to 12a3 and 13a1 to 13a3 are formed, for example, there is unevenness on the surface of the existing structure 90, and the seismic reinforcement formwork 94a, Even if the height of 94b is changed, it is possible to change the mounting height of the formwork retainers 17a and 17b, and in this respect as well, work for attaching the seismic reinforcement formwork 94a and 94b And workability can be improved.

Only the vertical member 13 side is shown with a through-batter receiving piece 19b having a recess 19b1 matched to the shape of the through-butter 95b attached to the corresponding position.

  However, in the case shown in FIG. 13, unlike the case shown in FIG. 11, since the through butter 95 a is not provided in the seismic reinforcement formwork 94 a, the first fixed vertical member 12 has the same structure as in the first embodiment. A similar form retainer 17a that does not correspond to a through-blade for a narrow space is used. Of course, as in FIGS. 10 and 11, the first fixed vertical member 12 may be fitted with the form pressing metal support 17 a ′ corresponding to the presence or absence of through flaps shown in FIG. 8.

  In addition, in the case shown in FIG. 13, unlike the case shown in FIG. 11, the height of the pair of seismic reinforcement formwork 94a, 94b is different, and the seismic reinforcement formwork 94a, 94b shown in FIG. 11 is higher than the seismic reinforcement formwork 94a, 94b shown in FIG.

  Therefore, in the case shown in FIG. 13, the higher one of the mold holding metal attachment holes 12 a 1 to 12 a 3 and 12 a 1 to 12 a 3 formed in the first fixed vertical member 12 and the movable vertical member 13 is attached. Using the holes 12a1, 12a2, 12b1, and 12b2, the height for attaching the mold retainers 17a and 17b ′ is set higher than that shown in FIG. 11, and the protruding ends of the mold retainers 17a and 17b ′ Adjustment is made so as to hit the tips of the seismic reinforcement molds 94a and 94b. In addition, this can also adjust height similarly in above-mentioned Embodiment 1. FIG.

  Therefore, according to the seismic reinforcement formwork support bracket 2 of the second embodiment, just by adjusting and tightening the adjustment bolt 15 at one location, similarly to the seismic reinforcement formwork support bracket 1 of the first embodiment.
