DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a landscape formwork method applied to the construction of concrete structures such as concrete dams, and a landscape formwork used in this method.

[0002]

2. Description of the Related Art Conventionally, concrete is cast using a steel or wooden formwork to form a scenic formwork on the first stage, and after the concrete is cured, a second-stage formwork is arranged. After that, concrete has been poured and then a method of constructing a scenic formwork in a stepwise manner has been carried out in the same manner.

In the above-mentioned construction method, it is necessary to install a formwork and cast concrete for each step, which is an inefficient construction method. For example, Japanese Patent Publication No. 58-6018 and Japanese Utility Model Publication No. 58-3873 As shown in the official gazette, a remodeling formwork method using blocks manufactured in a factory in advance has been performed.

[0004] JP-A-7-3801 discloses a simple retaining wall box for vegetation. This is a retaining box with a wire mesh box, which is a box for stabilizing the soil on the surface and performing vegetation.It does not correspond to the earth pressure, and is applied only when the earth pressure on the back is stable It is necessary to reinforce it using a special anchor when receiving earth pressure. Further, it is stipulated that the partition net in the wire mesh box is merely for reinforcement, and is not an essential element in the case of a small size.

[0005]

In order to construct a concrete retaining wall for the purpose of rehabilitation by a conventional formwork method, it is first necessary to manufacture a formwork having a complicated shape by hand, which is inefficient. In addition, there was a problem that it took too much time to install the system because it was not self-sufficient. Furthermore, in order to form irregularities on the surface of the concrete that has been cast, it is necessary to attach resin irregularities to the formwork side, but since the irregularities are damaged by the casting of concrete, there is a limit to diversion. is there. This leads to waste of petroleum energy, which is not preferable in terms of environmental protection.

[0006] In the construction method using the landscape formwork block disclosed in the above-mentioned publication, a cylindrical block whose vertical direction is open is slightly stacked between a lower side and an upper side and stacked on a stair. The entire inside is filled with earth and sand (customer soil), and vegetation is performed on the protruding (released) part on the lower side, but it is only built up in a step-like manner on the slope of the slope and it is not fixed with concrete, so it is a residential development land It can only be applied to slopes such as roads and road side walls, but not to places like dams. In addition, it is a structure that engages stacked blocks by the concave part formed at the upper end, so it is difficult to respond to complicated gradients, and when earth pressure is large, an anchor etc. is indispensable. Often constrained.

An object of the present invention is to clarify a scenic formwork method which can be easily used even under severe construction conditions such as a concrete dam, and a scenic formwork to be used for the method. .

[0010]

Next, the present invention will be described in more detail with reference to the accompanying drawings.

FIG. 1 shows one embodiment of a landscape formwork used in a landscape formwork method according to the present invention. Training landscape formwork 1
The 0 main frame 11 is formed in a lattice shape from metal or synthetic resin, and has a structure that can be folded because it is produced in a factory and transported to the site. The main frame 11 is the front frame 12
It is composed of a side frame 13 and a rear frame 14.

The inner space of the main frame 11 is defined by a partition grid frame 15 arranged in an inclined state, and a concrete filling section and a soil filling section are formed as described later. The inclination angle at which the partitioning grid frame 15 is attached can be set to any inclination state other than vertical.

The size of the grid (mesh) of the main frame 11 and the partitioning grid frame 15 is 5 to 20 mm because it is necessary to stop particles of concrete and soil. In addition, both members can also be comprised by the combination of a thick structural material and the net | network attached to this or a punched metal net | network.

The main frame 11 has a bottom frame 16 and an upper frame 1.
7 is attached. It is also a preferred embodiment to arrange the bracing to oppose the pressure at the time of placing concrete.

The bottom frame 16 and the top frame 17 are formed by the same grid as the main frame 11 and the grid frame 15 for partitioning.
The mesh is preferably about m.

The form in which the bottom frame 16 and the top frame 17 are not provided is also included in the landscape formwork of the present invention, but in such a form, it is preferable to arrange reinforcing members such as braces at the bottom and top. .

The present invention also includes a mode in which the bottom frame 16 is arranged only on the bottom surface of the later-described soil filling section 19.

As described above, the inside of the main frame 11 is partitioned by the partitioning grid frame 15, and
8 and the soil filling section 19 are formed. A mode in which a reinforcing bar for reinforcing concrete is arranged in the concrete filling section 18 is also included in the landscape formwork of the present invention.

The landscape formwork 10 shown in FIG. 1 is used continuously in the horizontal direction. Therefore, the present invention also includes a mode in which a continuous body is formed from the beginning, such as a triple in the lateral direction. In such an embodiment, the intermediate side frames 13 that are connected to each other are removed, and the partitioning lattice frames 1 that are long in the lateral direction are removed.
5 may be used.

In the embodiment shown in FIG. 1, the main frame 11 is integrated and foldable, but the front frame 12, side frame 13, and rear frame 14 forming the main frame 11 are independent. It may be configured to be assembled on site. Further, the front frame 12 and one side frame 13 and the rear frame 14 and the other side frame 13 may be assembled at a factory, and may be assembled on site.

Various methods such as a pin hinge and a grip can be applied as a joining method at the joining portion of each member.

Next, with reference to FIGS. 2 to 4, a method for constructing a landscape formwork according to the present invention using the above-described landscape formwork 10 will be described.

First, after the foundation concrete is cast, and after its curing, as shown in FIG. 2, the landscape-viewing formwork 10 is continuously arranged in the lateral direction on the foundation concrete surface, and the concrete filling section 18 is formed. Concrete is poured into the building. In addition,
It is preferable to fix the bottom surface of the arranged scenic view formwork 10 to the base concrete with concrete nails or the like.

The present invention also includes a construction method in which a sheet material is adhered to the inside of the partitioning grid frame 15 and the side frames 13 at the time of placing concrete.

Next, after the concrete placed in the concrete filling section 18 has been cured, concrete on the structure side is placed. In parallel with this operation, the soil filling section 19 may be filled with soil. The first stage is now complete. The second stage waits for curing of the concrete on the structure side, and arranges the scenic view formwork 10 rearward by an amount corresponding to the structure design line, fixing the bottom, placing concrete, filling the soil, and the like. The same process as in the first stage is performed. The same applies to the third and subsequent stages.

Planting or sowing vegetation is carried out in parallel with the filling of the soil or at the end of the whole process.

As shown in FIG. 4, when the structure has a gentle gradient or a steep gradient, the inclination angle of the partitioning lattice frame 15 is changed. As shown in the example of the gentle gradient (the left side of FIG. 4), it is not always essential that the partitioning grid frame 15 is continuous from the lower stage to the upper stage. For example, a part of the soil on the upper stage is part of the lower stage. The arrangement may be such that it is located on the upper surface of the concrete. In addition,
The aspect in which the partitioning lattice frames 15 as shown on the right side of FIG. 4 are vertically arranged is not included in the present invention.

In the method of repairing the formwork according to the present invention, after the filling of the soil is completed, the soil is sprayed from the front side of the front frame 12, which is indispensable for the method of the present invention. Is not an element. In addition, it is also preferable to perform planting on the surface of the front frame 12 so as to effectively prevent the loss of soil such as turf and dragon beard (snake beard).

Spraying resin material, mortar, or concrete instead of spraying the soil is also effective for improving the weather resistance of the net forming the frame.
Spraying water-permeable concrete containing fibers is more preferable for improving heat insulation.

In a preferred embodiment of the scenic formwork method according to the present invention, the water-permeable heat insulating material 20 is disposed inside or outside the front frame 12. The arrangement of the water-permeable heat insulating material 20 may cause too much water to accumulate in the filled soil, or cause the accumulated water to freeze and destroy the planting, and furthermore, the soil may be washed away. It is preferable to prevent the plants from getting stuck and maintain an environment suitable for planting and growing.

As the water-permeable heat insulating material 20, for example, a plate-like material such as foamed styrene, foamed ethylene, foamed polypropylene, foamed vinylidene chloride and the like is used.

[0032]

According to the present invention, since the landscaping formwork according to the present invention is manufactured in a factory, the quality can be stabilized, and no problem in strength occurs. In addition, mass production is possible, which can contribute to cost reduction. Because it is foldable or assembling,
Not only is it easy to store and transport, but it is also easy to work on site and can be handled by non-experts, making it possible to work significantly more efficiently than conventional formwork methods. . The inside of the landscape view formwork is partitioned by a partition grid frame,
Each section is filled with concrete and soil, and especially the concrete cast in the scenic formwork is firmly connected not only to the concrete in the upper and lower concrete filled sections, but also to the base concrete or structural side concrete. Therefore, it is a construction method that can be used even with a steep gradient.

Further, the mode in which the water-permeable heat insulating material is disposed on the front frame has an advantage that a soil environment suitable for growing plants can be maintained.
