Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a backrest-type assembling retaining wall in which a wall plate and a bottom plate are assembled at a required angle by using an assembling tool arranged on the back side.

[0002]

2. Description of the Related Art As a conventional structure of a prefabricated retaining wall, as disclosed in Japanese Utility Model Publication No. Hei 2-7970, a wall plate having a bottom beam at a lower part, a bottom plate supporting the wall plate, It is known that there is provided a stay beam for connecting between the rear surface of the wall plate and the top surface of the bottom plate, and the bottom beam, the bottom plate and the stay beam of the wall plate are respectively connected by connecting members such as bolts and nuts. Have been.

[0003] Compared to using a retaining wall block in which a wall plate and a bottom plate are integrally formed by molding, the assembled retaining wall of the above structure has much better stock / transportation efficiency and workability, and is significantly lighter. However, since the ends of the beam are fixed against the wall and bottom plates, the force concentrates locally and a large load is applied to the concrete structure at the connection point. However, there is a risk of causing cracks or breaks in the concrete structure, and there is a concern about safety.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide not only the advantages of the prefabricated retaining wall, such as high stock / transportation efficiency, good workability, light weight and low cost, but also the conventional prefabricated retaining wall. It is an object of the present invention to provide a leaning type assembling wall which prevents local concentration of a load as seen and does not cause a risk of cracking or breakage of a concrete structure.

[0005]

Means for Solving the Problems Hereinafter, the present invention will be described using reference numerals in the attached drawings. The feature of the present invention is that a support in which a concrete wall plate 1 and a bottom plate 2 are arranged on the back side. In the reclining type retaining wall assembled at a required angle by the metal fitting S, the support metal fitting S is formed by a pair of right and left vertical members 3 and 4 extending in the height direction of the wall plate 1 and a pair of right and left extending members in the depth direction of the bottom plate 2. Between the horizontal members 6 and 7, a connecting member 5 connected between a pair of left and right vertical members, a diagonal member 8 connected between the vertical members 3 and the horizontal member 6, and between the vertical members 4 and 7 The vertical members 3 and 4 are adhered and fixed to the upper surface of the wall plate 1, and the horizontal members 6 and 7 are adhered and fixed to the upper surface of the bottom plate 2.

[0006] In the backrest-type assembling retaining wall configured as described above, all or a part of the assembling work of the wall plate 1 and the bottom plate 2 performed through the support fitting S is performed at a factory stage or a construction site. The vertical member 3,
The angle between 4 and the horizontal members 6 and 7 is appropriately adjusted by changing the length of the diagonal members 8 and 9 according to the inclined surface to be maintained as shown in FIGS. Conservation slope 2
A required number of assembling retaining walls are installed side by side in the left and right direction on a base surface 19 formed by cutting and cutting 0, a required formwork is performed on the back side, and the backing concrete 21 embeds the support fitting S. It is cast as follows. Earth and sand 22 are buried behind the backfill concrete 21. In the retaining wall structure using this leaning-type assembled retaining wall, the oblique members 8 and 9 of the support fitting S are connected to the wall plate 1 and the bottom plate 2 via the vertical members 3 and 4 and the horizontal members 6 and 7. When a bending moment is applied to the wall slab 1 and the bottom slab 2, the loads are dispersed and supported along the longitudinal directions of the vertical members 3, 4 and the horizontal members 6, 7.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION In the illustrated embodiment, each of a wall plate 1 and a bottom plate 2 is a concrete structure composed of a reinforcing bar and ordinary concrete. A pair of right and left vertical members 3 and 4 made of an angle steel material are arranged in parallel with a distance between each other with the height direction as a longitudinal direction on the wall plate 1 and screwed into a nut-type insert 12 embedded and fixed in the wall plate 1. Bolt 1
0, it is tightly fastened and fixed to the rear surface of the wall plate 1. A connecting member 5 made of an angle steel material is bridged between a pair of right and left vertical members 3 and 4, and each end portion is fixed to the vertical members 3 and 4 by bolting or welding. A pair of right and left cross members 6 and 7 made of an angle steel material are arranged parallel to each other with a distance between them in the depth direction of the bottom plate 2 and screwed into an embedded and fixed nut type insert 15 opened in the bottom plate 2. The bottom plate 2 is fastened and fixed in close contact with the upper surface of the bottom plate 2 by bolts 13 to be provided. The diagonal members 8 and 9 made of angled steel are obliquely bridged between the vertical members 3 and the horizontal members 6 so that the inclination of the wall plate 1 is set to a required angle. The vertical members 3 and 4 and the horizontal members 6 and 7 are fixed by bolting or welding.

FIG. 1 shows a case where the wall plate 1 is steeply inclined, FIG. 2 shows a case where the wall plate 1 stands upright at 90 degrees, and FIG. 3 shows a case where the wall plate 1 is inclined more gradually than FIG. However, the height of the wall plate 1, the depth of the bottom plate 2, the width of the wall plate 1 and the bottom plate 2, the angle of the wall plate 1 and the bottom plate 2 are not limited to those shown in the drawing, and are to be maintained. Is appropriately changed according to the state of the inclined surface.

[0009]

As described above, the leaning type retaining wall of the present invention
Since the system is divided into a wall plate 1 and a bottom plate 2 and is assembled via a support bracket S when necessary, the efficiency of manufacturing, stocking, and transporting each component is improved. Also, since it can be easily assembled at the construction site, it is easy to construct a large-sized retaining wall and the workability is high. In addition, a pair of left and right vertical members 3 and 4 extending in the height direction of the wall plate 1 and a pair of left and right horizontal members 6 and 7 extending in the depth direction of the bottom plate 2 are attached to the support fitting S. A connecting member 5 connected between a pair of vertical members,
The vertical members 3 and 4 and the diagonal members 8 and 9 connected between the horizontal members 6 and 7, and the vertical members 3 and 4 are fixed to the upper surface of the wall plate 1 in close contact with each other. Is adhered to the upper surface of the bottom plate 2 so that the load is distributed along the longitudinal direction of the vertical members 3 and 4 and the horizontal members 6 and 7 and is supported by the wall plate 1 and the bottom plate 2. Therefore, there is no crack or breakage of the concrete structure due to local concentration of load, and a highly safe retaining wall structure can be accurately constructed.
