Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pseudo rock block having a surface texture similar to that of natural stone.

[0002]

2. Description of the Related Art Conventionally, it has been widely practiced to combine concrete blocks to form a river / coast structure.

However, such a type of river / coast structure is often unsuitable for the surrounding environment because it has an artificial feeling, and recently, a so-called pseudo-rock block whose surface is processed like a natural stone is used. By doing so, the device is designed to be in harmony with the surrounding environment as much as possible.

By the way, in this type of pseudo-rock block, a natural stone-like texture is usually exposed by providing natural stone-like irregularities on the front surface of the block body formed of concrete or by attaching natural stone that has been appropriately shaped. Most of them are.

Such a pseudo rock block is easy to manufacture and is useful for use in a place, etc., which is far away from the viewpoint and does not require much fineness. It is undeniable that when it is used for the maintenance of a hydrophilic space that is used, or when it is used in a place close to the viewpoint, it causes a considerable discomfort in terms of surface texture due to its manufacturing means.

[0006]

Therefore, according to the present invention,
A three-dimensional frame as a frame is attached to the anchor means of the base plate, while a plurality of plate-shaped rock pieces formed by using natural stone as a mold form the pseudo-rock shape to be formed through the anchor bar. In addition to attaching to the frame to the frame, an opening for introducing filling material is provided at the top of the pseudo rock shape, and the space between each plate rock piece and the gap between the plate rock piece and the base plate are closed with joint mortar, By filling the filling material into the pseudo-rock-shaped form made of these plate-shaped rock pieces, and by closing the opening as the filling material input port, it is extremely suitable for the texture of natural stone. It is intended to obtain a pseudo rock block with a close surface texture.

In this case, if a lifting anchor member is provided on the side portion of the base plate, it is very convenient when moving or installing the pseudo rock block.

[0008]

[Operation] In the pseudo rock block according to the present invention, the surface is formed by a combination of a plurality of plate-shaped rock pieces formed by using natural stone as a matrix, so that a pseudo rock block that is extremely close to the texture of natural stone can be obtained. Not only the shape and size, but also the color tone can be freely selected.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of a pseudo rock block according to the present invention will be described below in detail with reference to the accompanying drawings showing the manufacturing procedure thereof.

That is, the pseudo rock block A according to the present invention
Is an anchor plate in which concrete B is placed on a formwork 12 in which a reinforcing member 10 such as a welded wire mesh or a grid-like reinforcing bar is previously arranged, and before the concrete is hardened, an anchor reinforcing bar 16 is projected on the lower surface. The base plate 18 is formed by arranging and integrating the upper surface of 14 so as to match the top end of the concrete B.

Then, the three-dimensional frame 20 serving as the skeleton of the pseudo rock block is erected and fixed on the anchor plate 14 of the base plate 18 through attachment means such as mounting bolts provided in advance so as to project (see FIG. 1). In this case, the three-dimensional frame 20 is formed into a desired shape such as a cubic shape, a rectangular parallelepiped shape, a triangular prism shape, or a truncated trapezoidal shape by combining mountain steel or the like so as to form the skeleton of the pseudo rock block to be manufactured.

On the other hand, in addition to this, a natural stone is used as a matrix,
In addition, for example, a large number of plate-shaped rock pieces 22 formed by reinforcing concrete or mortar-based material with highly durable fibers or resin-based material and further reinforcing the mesh or the like in a sandwich form are prepared. in this case,
An attachment insert member 2 is attached at an appropriate position of each plate rock piece 22.
4 is buried and arranged (see FIG. 2).

Then, an anchor bar 26 is attached to the mounting insert member 24 of each plate rock piece 22, and the anchor bar 26 is attached to the frame 20 on the base plate 18 by means such as welding. At this time, the welded plate-shaped rock pieces 22 are attached to the frame 20 via the anchor bars 26 so that the overall shape of the welded plate-shaped rock pieces 22 is substantially the same as the pseudo-rock shape to be formed, and the pseudo-rock-shaped top portion (heaven An opening 28 to be a concrete pouring hole and an air vent hole is formed near the end (see FIG. 3).

Further, a joint mortar 30 such as a color mortar is filled in the gaps between the plate-shaped rock pieces 22 and the gaps between the plate-shaped rock pieces 22 and the base plate 18 with a pseudo-rock-shaped form 34 by filling with a joint mortar 30 such as a color mortar. Are formed (see FIG. 4). A lifting anchor member 32 is embedded in the side surface of the base plate 18.

Then, in the pseudo rock-shaped form 34, the filling concrete 3 is filled through the opening 28 formed near the top end thereof.
6 and the opening 2 after concrete is poured.
8 is a joint mortar 30 such as color mortar as described above.
To close (see FIG. 5). In this case, it goes without saying that depending on the shape and size of the opening 28, a plate-shaped rock piece having a predetermined shape may be used to close it.

The pseudo-rock block according to the present invention thus formed is, for example, as shown in FIG. 7, in a masonry jetty or the like in which natural stone of a necessary weight for design cannot be obtained, the natural stone to be spread over the mound. It will be preferably used as a material to replace stone.

[0017]

As described above, since the pseudo rock block according to the present invention has a surface texture extremely similar to natural stone, it is compared with a bare concrete block or a block in which only its surface is processed. In this case, there is little discomfort, and therefore, it can be suitably used in the maintenance of hydrophilic use spaces that people directly use and places close to the viewpoint, and compared to the case where ordinary concrete blocks are laid out. Since there is a suitable space, it is possible to grow closer to the natural environment such as plants growing and fish and insects inhabiting.

Further, since the bottom surface is flat and uniform, it is not only easy to install, but also stable against external force, and the overall shape can be determined by the combination of plate-shaped rock pieces. Although it is a concrete block of a single shape that can be manufactured in any shape and size, the surface texture of each block is different,
Since the texture and color can be set freely, the same landscape as when natural stones are used can be maintained.

Furthermore, since the plate-shaped rock piece has a sufficient thickness, even if the block surface is worn or damaged, the filled concrete is not exposed, and the appearance is the same as when natural stone is worn or damaged. In addition, it has various advantages such as being able to prevent even the destruction of nature associated with the collection of natural stone.

The preferred embodiment of the pseudo rock block according to the present invention has been described above with reference to the accompanying drawings. However, the present invention is not limited to this embodiment and does not depart from the spirit of the present invention. It goes without saying that various design changes can be made in.
