Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for forming a retaining wall which has an appearance as if natural stone was buried.

[0002]

2. Description of the Related Art Conventionally, as a method of forming a retaining wall 5 in which natural stone-shaped convex portions 10 are scattered (hereinafter, simply referred to as a conventional method), natural stone-shaped concave portions 1 are formed. A plurality of molds 2 interspersed with each other are erected in a standing manner, and a plate member 3 is made to interpose a predetermined interval with respect to the plurality of molds 2.
A method has been proposed in which (panel plates) are installed oppositely, concrete 4 is filled between the formwork 2 and the plate material 3, and after the concrete 4 hardens, the formwork 2 and the plate material 3 are removed.

By the way, according to this conventional method, there is no problem in forming the retaining wall 5 in which the rectangular blocks having the same shape as the form frame 2 are vertically and horizontally connected, but as shown in FIG. It is very troublesome to form the retaining wall 5 having a shape having an opening 11 having a smaller area than the formwork 2 at the position. That is, the formwork 2
Is designed to have a predetermined size (the size is determined), and it is easy to form the opening 11 having the same size as the mold 2, but the opening having an area smaller than the mold 2 is formed. Forming 11 is tricky.

Specifically, as shown in FIGS.
A plate member 3 is cut out at a position corresponding to the opening 11 formed in the retaining wall 5 and is arranged so as to be opposed to the formwork 2, and the tip edge is located at an appropriate position on the surface of the formwork 2 at the position of the opening 11. A partition plate 7 formed in the same shape as the concave portion 1 of 2 is erected, and the side surface of the partition plate 7 and the end surface of the cut plate material 3 are continuously provided, and the plate material 3 and the form 2
The space surrounded by the partition plate 7 and the partition plate 7 is filled with concrete 4.

However, the shape of the tip edge of the partition plate 7 is formed by an operator cutting the plate material 3 with a saw or the like, and the recess 1 of the mold 2 is a natural stone-shaped recess 1. Since the partition plate 7 has a very complicated surface, the tip edge of the partition plate 7 does not match the surface of the recess 1 cleanly after all, and as shown in FIG. There is a problem that a void a is generated between them, and thus the concrete 4 flows out from the void a (note that the same components as those in this embodiment are designated by the same reference numerals).

The present invention has a technical object to provide a method for forming a retaining wall which solves the above problems.

[0007]

The gist of the present invention will be described with reference to the accompanying drawings.

Form frame 2 in which natural stone-shaped recesses 1 are scattered
A plurality of them are erected in a row, and a plate material 3 is installed opposite to the formwork 2 with a predetermined interval therebetween, concrete 4 is filled between the formwork 2 and the plate material 3, and the concrete 4 is hardened. After that, the form 2 and the plate material 3 are removed to form a retaining wall 5 having a natural stone-shaped convex portion 10 on the surface and an opening 11 at an arbitrary position, which is scattered on the plate material 2. An overlapping member 8 having a partition plate 7 detachably attached to the mold 2 having the same shape as the mold 2 provided with the convex 6 that fits exactly into the concave 1 is provided, and a plurality of the molds 2 are arranged in series. At this time, of the plurality of molds 2, the polymerized member 8 formed in a shape matching the opening 11 is polymerized with the mold 2 at the position of the opening 11 formed in the retaining wall 5, and the predetermined size of the polymerized member 8 is obtained. The partition plate 7 is attached at the position of, and the plate material 3 is divided by the partition plate 7 to form a plurality of molds 2 and the molds 2. Concrete 4 was filled in a space surrounded by the set have been plate 3 and the partition plate 7, after the concrete 4 curing, the mold 2, the plate member 3, the partition plate 7, the polymerization member 8
The present invention relates to a method for forming a retaining wall, characterized in that the retaining wall 5 having the natural stone-shaped convex portion 10 and having the opening 11 at an arbitrary position is formed by removing the retaining wall 5.

[0009]

The opening 11 formed in the retaining wall 5 is the overlapping member 8 having the same shape as that of the mold 2 provided with the convex portion 6 just fitted in the concave portion 1 of the mold 2.
And the partition plate 7 is erected at a predetermined position of the overlapping member 8, and the overlapping member 8 with the partition plate 7 is overlapped with the mold 2 at a desired position and the partition plate 7 is formed. The plate material 3 is divided by the above, and the space between the formwork 2, the plate material 3 and the partition plate 7 is filled with concrete 4, so that there is no gap a between the recess 1 and the partition plate 7 as in the conventional method. The concrete 4 does not flow out from the void a.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 4 and 5 show an embodiment of the present invention, which will be described below.

FRP with natural stone-shaped recesses 1 scattered
A plurality of molds 2 made of a product are formed, and a plurality of the molds 2 are vertically and horizontally arranged so as to stand upright at a predetermined place.

Subsequently, the concave portion 1 of the mold 2 is transferred (molded) to form a polymerized member 8 made of foamed resin (urethane foam, styrofoam) having a convex portion 6 on the surface.

Subsequently, the overlapping member 8 is cut in accordance with the size of the opening 11 (see FIG. 1) formed in the retaining wall 5. Since the polymerized member 8 is made of foamed resin, it can be easily cut.

Subsequently, the polymerizing member 8 is polymerized on a predetermined portion of the mold 2 at the position of the opening 11 in a state where the concave portion 1 and the convex portion 6 are fitted (adhesion polymerization with an adhesive or the like), In consideration of the opening 11, a straight partition plate 7 is made to face a predetermined portion of the overlapping member 8 and adhered by an adhesive or the like to stand upright.

Subsequently, a plate member 3 (panel plate) having a predetermined portion cut off in consideration of the opening 11 is erected at a predetermined interval with respect to the form 2, and the side surface of the partition plate 7 and the plate member 3 cut off. Glue with the end face of.

Although the drawing shows the case where the retaining wall 5 having the opening 11 formed at one place is formed, when the plurality of openings 11 are formed, a plurality of overlapping members 8 are prepared in the same manner as above. .

Then, according to a conventional method, a foam tie 9 and a single tube 1
The plate material 3 and the formwork 2 are fixed by 2 and subsequently, the space surrounded by the plate material 3, the formwork 2 and the partition plate 7 is filled with concrete 4, and when the concrete 4 hardens, the plate material 3 and the formwork 2 Then, the overlapping member 8 is removed to form the retaining wall 5 having the natural stone-shaped convex portion 10 and the opening 11.

As described above, in this embodiment, since the overlapping member 8 having the convex portion 6 which is fitted exactly into the concave portion 1 of the mold 2 is used, the mold 2 and the leading edge of the partition plate 7 are separated from each other as in the conventional method. Gap a between
Are not formed, and therefore voids as in the conventional method.
The problem that concrete 4 flows out from a does not occur.
