Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a slope-covered structure in which natural stone is layered on the surface.

[0002]

2. Description of the Related Art In a conventional concrete block wall masonry structure, a concrete block itself to be laid has a retaining portion, and concrete is poured between the blocks to be integrated.

[0003]

In the conventional masonry structure of the concrete block wall, since the surface is constituted by the concrete portion, the surrounding masonry joint of the block is combined with the presence of the artificial joint joint of the block. The harmony with the natural environment was spoiled, and the integration of each block was difficult.

The present invention has been proposed in view of the above problems of the prior art, and its purpose is to be in harmony with the surrounding natural environment, to be excellent in workability, and to be structurally reliable. The point is to provide a high natural slab formwork block construction method.

[0005]

In order to achieve the above-mentioned object, a method of constructing a natural stone block form block according to the present invention is a method in which natural stones are lined up on a pedestal in which a wire mesh is stretched on a steel angle member. Adhering to the wire mesh via an adhesive, the angle member,
An integrated piece of wire mesh and natural stone is dropped into a formwork in which concrete has been poured in advance, and after the concrete has hardened, it is demolded to produce a natural slab formwork block with integrated natural stone on the surface. The lower natural stone slab formwork block is installed and fixed to the foundation concrete at a predetermined position and a gradient through the foundation fixing hardware attached to the back, and then the upper fixing bracket is inserted on the rear face of the lowermost natural lithographic formwork block. It is attached via bolts, the on-site concrete is poured between the back-filling part and the first concrete placing surface, and then the second-stage natural stone formwork block is lifted up to the lowermost natural stone formwork block. Installed at a predetermined position on the upper surface and connected to the upper fixing bracket, and then attaching the upper fixing bracket to the upper rear surface of the second stage natural stone block form block, And Da設 concrete to the 2nd step hitting 設面, is characterized in that recurring said same steps below.

BEST MODE FOR CARRYING OUT THE INVENTION The most preferred embodiment of the present invention shown in the drawings will be described below. Steel angle material 1
The wire mesh 2 is stretched over the frame body made of to form a pedestal, and natural stones 3 are lined up on it and bonded with an adhesive 4 such as an epoxy resin to integrate the wire mesh 2 and the natural stone 3, (See FIG. 1 (a)) Thus, the integrated wire mesh 2 and natural stone 3 is filled with concrete 5 in advance and dropped into the mold 6,
(See FIG. 1B) After the concrete 5 is hardened, the mold 6 is demolded to manufacture the natural slab formwork block 7 integrated with the natural stone 3. (See FIGS. 1C and 1D) Next, a method of constructing the natural slab formwork block configured as described above will be described.

[0007] Concrete is poured and the foundation work 8 is constructed (see Fig. 2). On the foundation work 8, the lowermost natural slab formwork block 7 is mounted via the fixing metal fittings 9 attached to the back surface thereof. A predetermined position and slope are secured and fixed to the foundation work 8. (Refer to FIG. 6) In the fixing bracket 9, the vertical part of the lower L-shaped part is fixed to the natural lithograph form block 7 through the insert bolt, and is diagonally above the tip of the horizontal part of the L-shaped part. The tip end of the inclined piece extended to is fixed to the back surface of the block 7 through an insert bolt. After fixing the lowermost natural slab formwork block 7 to the foundation work 8 through the fixing metal fittings 9, concrete 11 is placed between the block 7 and the back-filled crushed stone 10 for the first concrete placing surface S.
_Add up to ₁ . (See FIG. 3) and then the second stage natural slate mold block 7 'are lifted placed in position, the block 7' attached to the upper fixing bracket 9 to the concrete to the second step hitting設面S ₂ later scold Place 11 Thereafter, the above steps are repeated, and finally a natural lithographic form block is arranged at the top end.

In the figure, reference numeral 12 is a drain hole.

[0009]

As described above, according to the present invention, natural stones are lined up on a pedestal in which a wire mesh is stretched on an angle member, and the natural mesh is adhered to the wire mesh with an adhesive, whereby the wire mesh and the natural stone are integrated. The naturalized stencil form block is manufactured by dropping the solidified product into a formwork in which concrete has been poured in advance, and then removing the mold after the concrete has hardened. An L-shaped piece of the fixing metal fitting is provided on the back surface of the same frame block as a frame, and a vertical piece of the L-shaped piece is attached to the back surface of the block and an inclined piece extending obliquely upward from the horizontal piece is attached. The natural lithographic form block is sloped by combining with the upper block back surface of the form block and stacking the form blocks and filling concrete 11 between each form and backing material. One Compared with conventional retaining walls, there are no vegetation parts and there are no joints between blocks, and it is possible to deal freely with any slope gradient and further, concrete between the block and backing material The block is integrally coated on the slope, so that the construction is simplified and the construction cost is reduced.
