Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a masonry retaining wall using natural stone.

[0002]

[Prior art]

 Conventionally, stone walls using natural stones have been used in various forms such as masonry masonry with rubble stones, random piles of natural stones, and castle wall piles in various forms such as residential land.

[0003]

[Problems of conventional technology]

 However, safety standards for retaining walls have been established to ensure the safety of cliffs, and on the other hand, due to the shortage of masonry, the conventional retaining walls made of natural masonry have hardly been constructed recently. .

The masonry retaining wall that partially satisfies the safety standards has a formwork on the back side, and reinforced concrete etc. are laid up to stack the stone materials one step at a time, and a back-filling concrete is placed, from the surface side of the stone material. There is a method of filling the voids between each stone with joint cement, stacking more stones after concrete hardening, and proceeding with the same work.However, a stone masonry retaining wall using such natural stones is special for construction. However, these masonry retaining walls are mostly replaced by concrete-exposed concrete retaining walls, which requires natural skills and is inefficient and time-consuming. There are drawbacks such as lack of feeling.

[0005]

[Problems to be solved by the device]

 Therefore, the present invention intends to provide a masonry retaining wall that enables a person without special skills to efficiently and easily perform masonry and at the same time secures safety as a retaining wall.

[0006]

[Means for solving the problem]

 The structure of the retaining wall according to the present invention has joints of natural stones 2, 2 ... at a certain distance on the surface side of the preformed L-shaped or inverted T-shaped concrete retaining wall body 1. The concrete 3 is piled up with the concrete 3 interposed, and the lining concrete 4 is filled in the gap between the concrete retaining wall body 1 and the piled natural stones 2, 2.

In this case, the concrete retaining wall body 1 is made of precast concrete, and is devised for stacking the natural stones 2, 2, ... on the surface and safety for ensuring safety as a retaining wall. Although it has a shape that meets the standard, in order to efficiently stack various shapes of natural stones 2, 2, ... Stacked on the surface, fixed studs 5, 5, ... Are embedded in the concrete retaining wall body 1. The reinforcing bar 6 and the wire mesh 7 are fixed, and further, the binding anchor 8 is hooked on the reinforcing bar 6 or the wire mesh 7 (either alone or in combination), and the tip of the binding anchor 8 is joined to the joint concrete. It is embedded in 3 and fixed so that natural stones 2, 2, ... Can be stacked easily and surely.

In the figure, 10 is a mounting hole for mounting the drainage pipe 9, and 11 is a driving groove for driving the backing concrete 4.

Various kinds of reinforcing bars 6, wire nets 7 or tightly anchored anchors 8 can be prepared and appropriately used depending on the purpose of construction of the retaining wall, the size of natural stone and the like.

【effect】

 According to the present invention, as described above, fixing studs 5 and 5 are projected on the surface of the concrete retaining wall body 1 which is L-shaped or inverted T-shaped to fix the reinforcing bar 6 or the wire mesh 7, A binding anchor 8 is hooked on the reinforcing bar 6 or the wire net 7, and the tip of the binding anchor 8 is piled up on the front side. The natural stone 2 is embedded in the joint concrete 3 between the natural stone 2 and the natural stone 2. 2 and the concrete retaining wall main body 1 are filled with a lining concrete, so natural masonry work can be done in order along the rebar 6 or the wire mesh 7 in the factory. Not only the assembling work, but also the assembling work at the site can be done easily, and a reliable retaining wall can be made by a simple work without requiring skill.
