  When arrange | positioning the said decorative board part along the side surface of a concrete structure, it is preferable that the said reinforcing rib protrudes toward diagonally upward from the back surface of a decorative board part. If it does in this way, it will become difficult to form an air pool under a reinforcement rib, Therefore It becomes possible to fill concrete around a reinforcement rib without gap.

  In the formwork unit according to the present invention, when the above-mentioned formwork constituent members adjacent to each other are connected by a vertically connected body, it is preferable to fix the vertically connected body to the reinforcing rib. If it does in this way, it will become possible to prevent the opening between formwork constituent materials.

  In the formwork unit according to the present invention, a joining key may be interposed between the formwork constituents adjacent to each other in the vertical direction, and the formwork constituents may be engaged with each other via the joining key. Specifically, an upper receiving groove that opens upward and an upper engaging portion that is positioned above the upper receiving groove are provided at the upper end of the lower mold forming member, and the upper mold forming configuration. A lower housing groove that opens downward and a lower engagement portion that is positioned below the lower housing groove are provided at a lower end portion of the material, and the lower engagement portion is inserted into the upper housing groove, and the lower housing The upper engagement portion may be inserted into the groove, and a coupling key may be interposed between the upper engagement portion and the lower engagement portion. By doing so, the coupling key prevents the lower engagement portion from coming out of the upper housing groove, and the upper engagement portion from coming out of the lower housing groove is blocked by the coupling key. It becomes possible to suppress the opening of adjacent formwork constituent materials.

  In the residual formwork according to the present invention, it is preferable to connect the adjacent formwork units with a laterally connected body. If it does in this way, it will become possible to prevent the opening between formwork units.

  In the remaining formwork according to the present invention, a waterproof structure may be provided at the joint between adjacent formwork units to close the joint. The waterproof structure includes a bolt projecting from the back surface of the decorative plate portion, a waterproof packing that covers the joint from the back surface side of the decorative plate portion, a press plate disposed on the back side of the waterproof packing, It is good to form with the nut arrange | positioned at the back side of a holding plate. In this case, the bolt is passed through the presser plate, and the nut is fastened to the shaft portion of the bolt protruding from the presser plate. If it does in this way, since the waterproof packing pressed by the pressing board will be pressed against the said decorative board part, leakage of cement paste etc. can be prevented.

  A bridge wall rail according to the present invention is a bridge wall rail provided with a residual mold disposed on a side portion of a floor slab and a wall body made of reinforced concrete formed on the back side of the residual mold. The residual mold has a plurality of mold units connected in the bridge axis direction, and each mold unit has a plurality of mold components constituting the vertical direction, Each formwork component is made of an aluminum alloy extruded profile, and includes a decorative plate portion that also serves as a dam plate and an exterior, and a reinforcing rib embedded in the concrete of the wall body. .

  Subsequently, although illustration is omitted, concrete is placed between the remaining mold K and the mold W3, and the reinforcing ribs 12, the longitudinally coupled bodies 3, the laterally coupled bodies K3, the brackets B, and the like are embedded in the concrete. Although there are a large number of reinforcing ribs 12, 12,... On the back surface of the remaining formwork K, each reinforcing rib 12 projects obliquely upward, so that the concrete is smoothly above the reinforcing ribs 12. It is led to the decorative board part 11 side, and it becomes difficult to form an air reservoir below the reinforcing rib 12. Further, in the remaining mold form K of the present embodiment, the formwork components 1, 1,... Are integrated by the longitudinally connected body 3 (see FIG. 3), and the coupling key 2 (see FIG. 4A). ) Prevents the opening on the surface side of the mold component members 1, 1, and the horizontal connection body K 3 (see FIG. 3) allows the mold unit K 1, K 1 to be integrated and the waterproof structure K 2. Since the joints of the mold units K1, K1 are closed by (see FIG. 3), leakage of cement paste and the like from the remaining mold K can be prevented.

  When the concrete reaches the demolding strength, only the mold W3 is demolded. The remaining mold K is left as it is without removing the mold.

  As described above, according to the remaining formwork K according to the present embodiment, it can be efficiently installed, so that the construction work of the bridge wall rail W can be performed quickly and efficiently. Become. Moreover, since the surface of the bridge wall rail W is covered with the decorative plate portion 11, the aesthetic appearance of the bridge wall rail W is improved and the durability of the concrete is improved.

  Moreover, in this embodiment, since the reinforcement rib 12 has protruded diagonally upward from the back surface of the decorative board part 11, concrete can be filled into the circumference | surroundings of the reinforcement rib 12 without gap.

Note that the configuration of the remaining mold K may be changed as appropriate.
For example, in this embodiment, the case where the formwork units K1 and K1 are coupled by the laterally coupled body K3 using the longitudinal members 31 and 31 is illustrated, but as shown in FIG. The formwork units K1 and K1 may be connected by an independent horizontal connection body K5.

  As shown in FIG. 8B, the lateral connection body K <b> 5 includes a connection back plate 81 in addition to the attachment piece 82, the bolt 83, and the nut 84. The connecting back plate 81 is disposed on the rear side of the attachment piece 82 and is fastened to the attachment piece 82 by a bolt 83 and a nut 84. The lower end portion of the attachment piece 82 is located on the front side of the distal end portion of the reinforcing rib 12 and is engaged with the distal end portion of the reinforcing rib 12 from the decorative plate portion 11 side, like the attachment piece 32 shown in FIG. To do. Although not shown, the lower end portion of the connection back plate 81 and the lower end portion of the attachment piece 82 receive the fastening force of the bolt 83 and the nut 84 and sandwich the tip end portion of the reinforcing rib 12.

  Even in such a laterally connected body K5, it is possible to prevent the opening between the mold unit K1, K1.

  In the present embodiment, the remaining mold K (former unit K1) having a cross-sectional shape is illustrated, but the shape of the remaining mold K is not limited. As shown in (a) of FIG. 9, there is no problem even if the remaining mold K has a linear cross section.

  If the remaining mold K has a straight cross section, the cross section of the mold components 1, 1,... Can be made the same, so that the mold unit K1 can be formed with one type of extruded profile. It becomes. In the remaining mold K shown in FIG. 9A, the cross-sectional shapes of the upper edge mold member 1A and the lower edge member 1B are different from those of the other mold members 1. However, the raw extruded shapes are the same.

  As shown in FIG. 9B, the upper edge mold member 1 </ b> A can be obtained by cutting a part of the extruded shape member having the same cross-sectional shape as that of the mold member 1. Similarly, the mold component 1B for the lower edge can be obtained by cutting a part of an extruded profile having the same cross-sectional shape as the mold component 1 as shown in FIG. 9C. . It is also possible to form the lower edge formwork component 1B using the part cut out when forming the upper edge formwork composition 1A.

  In this embodiment, although the case where the residual formwork K was applied to the bridge wall rail W was illustrated, it is not the meaning which limits the application range of the residual formwork which concerns on this invention. Although illustration is omitted, the remaining formwork according to the present invention can be applied when building concrete walls, columns, beams and the like in other civil engineering structures and building structures other than bridges.
