Description

  The present invention relates to wall concrete, a method for producing wall concrete, and a method for constructing wall concrete.

  Conventionally, a general wall concrete construction means first constructs a temporary scaffold for assembling a formwork, and forms a formwork while supporting a plywood veneer wooden formwork or steel steel formwork with a temporary material called a supporter. There are the most construction methods in which reinforcing bars are assembled on the inner side to construct an inner formwork, and then concrete is poured and the formwork material is disassembled after drying and curing.

An outline of a conventional wall concrete construction method and configuration will be described with reference to FIG.
That is, FIG. 4 shows the configuration of the wall concrete 16 at the time of completion. However, as understood from FIG. 4, conventionally, in order to construct the wall concrete 16, the temporary worker scaffolds 14 and 15 are provided. Must be installed.

In addition, it is a premise that the retaining wall 6 and the earthwork part 8 of FIG. 4 have already been completed.
As a construction method, first, the rebar 21 is assembled to construct the mold 9, and an appropriate steel material 29 and an appropriate pipe member 11 are reinforced with a mold support 22 composed of appropriate screw means 12 and the like. Then, by installing the face plate 23, the formwork support 13 is completed.

After the mold support 13 is completed, the concrete 20 is poured into the space where the reinforcing bars 21 formed between the molds 9 are interposed.
After the concrete 20 is poured and the concrete 20 is sufficiently hardened, the formwork supporting work 22 and the formwork 9 are removed to complete the wall concrete 16, and then the temporary scaffolds 14 and 15 are disassembled and constructed. The work is complete.

  In this construction method, since the height of the retaining wall 6 is generally higher than the human body, the temporary scaffolds 14 and 15 must be installed, and the construction of high-cost and long-term wall concrete is necessary. It has become work.

  Recently, the height of the retaining wall has increased considerably. However, the surface portion 30 that is a flat portion formed on the upper portion of the base portion that is the earthwork portion 8 on which the retaining wall is formed. There is an increasing number of works that require the wall concrete 16 to be formed on the end edge portion 31. To that end, an operator needs to perform a predetermined work from the outside of the retaining wall.

  Therefore, although it is absolutely necessary to install the temporary scaffolds 14 and 15, it has become difficult to install the temporary scaffolds 14 and 15 and a problem that the cost greatly increases occurs. ing.

  Similarly, as in highways and bridges, there is a space at the end of the road or the end of the bridge where the wall concrete is to be formed, in other words, below the base. Therefore, since it is impossible for a worker to directly perform the work of installing the wall concrete from the outside of the base part, it is absolutely necessary to similarly install the temporary scaffolds 14 and 15. However, problems similar to those described above have occurred.
