DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an artificial wall for free climbing, and more particularly to an artificial wall for free climbing which has a shape similar to an actual rock wall and a rock surface, and is highly safe and durable.

[0002]

2. Description of the Related Art In recent years, artificial walls for free climbing (hereinafter referred to as artificial walls) have been used as artificial rocks for training.
Have been installed in indoor athletic facilities and the like. Originally, free climbing is a sport that requires advanced technology of climbing (climbing) natural rock walls without using artificial equipment, but as a place to learn climbing technology for that purpose, These facilities are widely used as a place for conducting climbing competitions.

[0003] The most basic type of artificial wall uses the wall surface of an existing concrete structure, but in this case, it is often a straight wall over the entire height, and an overhang (forward inclined wall) or the like is provided. And the change in wall shape tended to be poor. Therefore, artificial walls designed for free climbing have become mainstream. FIG.
It is explanatory drawing which showed the state in which the climber C is climbing such an artificial wall 50. This artificial wall 50 has a flat panel 60 of a unit unit as shown in FIG.
It has a structure attached vertically and horizontally to a support structure composed of a steel frame (not shown). Generally, a plywood or a fiber reinforced plastic plate (hereinafter, referred to as an FRP plate) is often used for the flat panel 60. Since the surface of the plywood is smooth, a large number of projecting holders 61 of various shapes are attached to the panel surface with bolts 62 or the like so that climbing can be performed from various routes. In addition, a hold can be attached to the FRP plate, but a simple uneven shape is formed on the surface of the formwork, and cracks (cracks) 63 and edges corresponding to the hold are formed on the surface of the FRP plate. Can be formed. A flat panel 60 of this type of FRP board
When the artificial wall 50 is constructed by combining the above, as shown in FIG. 12, it is possible to construct an overhang that projects toward the near side as it becomes the upper part of the wall surface, which is particularly effective as a place for indoor training.

[0004]

However, the conventional FRP
The wall surface of the artificial wall made of a plate or the like is merely formed with a simple uneven shape, and cannot have a feeling close to that of an actual rock wall. Also, as shown in FIG. 11, the entire shape of the artificial wall has a predetermined inclination angle set in the vertical direction in the flat panel, but since it is arranged in a row in the horizontal direction, it does not feel as an artificial facility. can not deny. Further, since the thickness of the FRP plate constituting the flat panel is thin, an artificial reverberation sound is generated due to an impact during climbing or the like, and it is not a situation where a realistic feeling of climbing a rock wall can be enjoyed.

[0005] Further, when an artificial wall using FRP board panels is constructed outdoors, the service life has to be shortened in consideration of the influence of deterioration of the FRP board and the like. Also, F
Since the RP board is flammable, sufficient attention must be paid to fire when constructing and using artificial walls. For this reason,
There has been a demand for an artificial wall that can be used as a permanent outdoor facility that ensures safety from the time of construction to the time of use after completion.

Accordingly, an object of the present invention is to provide an artificial wall for free climbing which solves the above-mentioned problems of the prior art, has a shape and a rock surface close to the actual rock wall, and has sufficient durability even outdoors. Is to do.

[0007]

In order to achieve the above object, the present invention has a flat panel having a predetermined shape formed by molding a short glass fiber reinforced mortar and a plurality of types of curved surface patterns made of the same material. The present invention is characterized in that an ascending rock wall covering the periphery of the frame structure is formed by combining with a curved panel and attaching the frame structure to a panel support hardware having a frame structure which has been constructed in advance.

In this case, it is preferable that the shape of the curved panel projected from a direction perpendicular to the surface is substantially equal to the plane shape of the flat panel.

It is preferable that the curved panel has a curved surface whose edge shape is a straight line or a combination with a curve having a predetermined shape, and whose side shape smoothly changes gradually toward the other side.

[0010] It is preferable that each corner of the flat panel or the curved panel attached to the panel support is substantially vertical.

It is preferable that the flat panel and the curved panel are short glass fiber reinforced mortar plates formed by using a mold formed by molding an actual rock surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the artificial wall for free climbing (hereinafter referred to as an artificial wall) of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a perspective view showing the overall shape of the artificial wall 10 of the present invention. The illustrated artificial wall 10 is constructed along the actual rock wall 1, and the rock wall 1
Three surfaces 10a, 1a of the artificial wall 10 so as to cover a part of the surface of the artificial wall 10.
0b and 10c constitute a wall surface. Slab concrete is cast on a deck plate (not shown) on the top end surface 11 of the portion surrounded by the artificial wall 10. Each wall is composed of a plurality of wall panels 12 arranged without gaps,
Each wall panel 12 is fixed to a support steel frame (not shown). Wall panel 1 constituting artificial wall 10 of the present embodiment
The shape of No. 2 is composed of a flat panel 12A and 13 types of curved panels 12B as shown in the panel pattern list in Table 1 below. For comparison of the size of the artificial wall 10, a climber C climbing a wall surface and a belayer B securing the climber C on the floor 2 are shown.

[0013]

[Table 1]

As shown in the table, the plane shape of the curved panel 12B projected in the direction perpendicular to the plane is a square having the same size as the flat panel 12A (one side is 100).
Further, as shown in FIG. 2, each edge shape of the curved panel 12B is set so that the height of the panel apex is 100 or 50, that is, equal to one side of a square or 1/2 of one side. It is constituted by a curve having a predetermined curvature R and a straight line. As shown in FIG. 4, for example, the curved surface shape surrounded by the edge is set so as to gradually change so that the matching with the opposite side and the adjacent side becomes smooth. At this time, the range of the distance L from the vertex of the corner portion 13 of the wall panel 12 to the edge along the edge forms a planar shape, and serves as a portion for fixing the wall panel 12 to the pedestal plate 34 of the panel support hardware 33 as described later. Therefore, as shown in FIG. 3, the panel surface forms a vertical plane in the vicinity of the intersection 20 where the four wall panels 12 having different curved patterns are adjacent to each other. For this reason, it is possible to simplify the position determining operation of attaching the panel support hardware 33 (not shown) to the support steel frame described later and the attachment operation of fixing the corner 13 to the panel support hardware 33 with bolts or the like.

Next, the configuration of the wall panel 12 will be described with reference to FIGS. The wall panel 12 constituting the artificial wall 10 of the present invention is made of a GRC mortar in which short glass fibers are mixed in a mortar obtained by mixing GRC cement and silica sand as fine aggregate at a predetermined water cement ratio. The GRC mortar is cast into a molding die (not shown) having a predetermined shape by a direct spray method, and solidified in the molding die to form the wall panel 12. In casting, the GRC mortar is divided into a plurality of layers in the mold and sprayed on a thin layer, and each GRC mortar layer and a thin reinforcing metal mesh (mesh size of about 200 mm) are alternately laminated to finish the panel. The mold used for this molding is a silicone resin mold that precisely molds the rock surface of the actual rock wall, and a backup FRP that prevents deformation of the flexible silicone resin mold.
It consists of a mold frame. The silicone resin mold and the FRP mold are overlapped and integrated as a single mold, and GRC is placed in the mold.
Spray the mortar several times so as to stack. It is preferable that the GRC mortar is colored into a natural color by mixing a pigment such as ocher or brown into the sprayed GRC mortar. The sprayed GRC mortar is pressed and shaped using a defoaming roller or a small hand so that each layer is in close contact. As a reinforcing material for the wall panel 12, besides a wire mesh, a mesh of a predetermined mesh made of aramid fiber or carbon fiber is suitable.

The wall panel 12 in the mold is removed from the mold after a predetermined steam curing step and an air curing step. On the surface of the removed wall panel 12, as shown in FIG. 4, an elaborate and realistic uneven shape close to an actual rock surface, a crack 16 and the like are reproduced. In addition, the roughness of the surface of the wall panel 12 as a texture can be expressed by the silica sand contained in the GRC mortar.

FIG. 4 shows a panel pattern No. shown in Table 1. FIG. 4 is a perspective view showing a wall panel 12 by taking 4 as an example.
As shown in the figure, a plurality of hold mounting holes 14 are formed at arbitrary positions on the wall panel 12. Prior to the spraying step, a cylindrical mold (not shown) is attached to a molding die to form the hold mounting hole 14, and GRC mortar is sprayed around the cylindrical mold to sufficiently cover the whole. It is preferable to shape it with a roller or the like. As shown in FIG. 5, a corner 13 of the wall panel 12 is formed.
Is reinforced by increasing and spraying GRC mortar so that the thickness of the plate becomes thicker than that of the general part. In addition, this corner 13
