2. Description of the Related Art Generally, when laying a concrete structure on a predetermined construction surface, a mold is made from a wooden frame, a concrete material is filled in the mold, and the wooden frame is removed after the concrete material hardens. Method is used.

However, when the concrete structure to be laid is a relatively long one such as a center barrier installed in the median strip of an expressway,
Since the wooden frame must be assembled and disassembled by the length, not only the work becomes extremely complicated but also the work efficiency is extremely disadvantageous.

Therefore, as a conventional technique suitable for manufacturing such a concrete structure, for example, Japanese Patent Laid-Open Publication No.
The one shown in Japanese Patent Publication No. 8-82632 is provided. That is, according to this conventional technique, a form is provided on a machine body that can be advanced by a drive device, and the machine body is advanced while filling the mold body with concrete material, thereby responding to the cross-sectional shape from the rear end opening of the mold. The concrete structure is continuously laid.

According to such a conventional technique, assembling a wooden frame
Since disassembling is not necessary, it becomes possible to lay a relatively long concrete structure easily and efficiently.

[0006]

By the way, in the above-mentioned prior art, since the mold is moved during the filling of the concrete material, the surface of the concrete structure may be scratched. Further, after the formwork has passed, no restraint force acts on the concrete structure, which may cause deformation such as swelling or drooling.

Therefore, in the actual construction, it is the actual situation that the operator always stands by and corrects the deformation such as scratches, swelling, and drooping, which is not always preferable in terms of workability. Absent.

Moreover, since the surface of the laid concrete structure merely presents a simple surface with which the formwork is in sliding contact, the appearance is dry and tasteless.

In view of the above situation, it is an object of the present invention to provide a concrete structure manufacturing apparatus capable of further facilitating the work and easily improving the appearance quality.

Adjust the position.

Although the above-mentioned embodiment exemplifies the apparatus for manufacturing the center barrier laid in the median strip, it is not limited to the center barrier, and side walls, curbs, etc.
Of course, other concrete structures can be applied as long as they are relatively long and laid. Further, although the embossing roller is illustrated as the rolling member, it does not necessarily have to be a roller-shaped member, and the same operational effect can be expected even if a belt-shaped rolling member is applied, for example. is there. Further, the rolling member does not have to be one for each surface of the concrete structure, and a plurality of rolling members may be provided on the surface of the concrete structure. In this case, not only the concrete structure having a cross-sectional shape as shown in FIG.
As shown in (a) and FIG. 6 (b), a plurality of rolling members 130a, 130b, 130c, 130d and a plurality of rolling members 130e, 130f, 130g, 130h are used to form a concave curved surface Ea and a convex curved surface Eb. Even a concrete structure A'having a surface, or FIG.
As shown in (a) and FIG. 7 (b), the plurality of rolling members 130j, 130k, and 130l allow a plurality of planes E to be formed.
Even a concrete structure A ″ having a surface composed of c, Ed, and Ee can be corrected and patterned for each scratch and deformation. However, as shown in FIGS. 6 and 7. The arrangement mode of the plurality of rolling members, that is, the plurality of rolling members arranged alternately in front and back is merely an example, and for example, the plurality of rolling members may be arranged in a stepwise manner. But of course it doesn't matter.

Further, as the rolling member, it is not always necessary to apply a member provided with unevenness for forming a pattern. In this case, a dedicated means for patterning may be separately provided. As a dedicated means for patterning, it is not always necessary to roll on the surface of the concrete structure, for example, a plate-like member is provided so as to be in sliding contact with the surface of the concrete structure, and the plate-like member may be provided with irregularities. It doesn't matter. The pattern formed on the concrete structure is not limited to that of the above-described embodiment. Furthermore, by preparing a plurality of embossing rollers having different irregularities and exchanging them appropriately, the pattern formed on the concrete structure can be easily changed.

[0027]

As described above, according to the present invention,
Since the rolling member is rolled on the surface of the uncured concrete structure, it is possible to correct the deformation such as scratches, swelling, and drooping by rolling the rolling member. Ru can be facilitated made.
