BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressure receiving material used for retaining soil such as slopes and stabilizing slopes.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 5, a pressure-receiving material for anchor work used for retaining soil such as slopes and stabilizing slopes has a plane cross shape having a through hole 1 with its front and back surfaces opened at the center. It is made of concrete, and the pressure receiving member 2 is arranged on the slope, the tensile member fixed in the through hole 1 is penetrated, and the pedestal and the pressure bearing plate are sequentially fitted to the tensile member protruding on the surface of the pressure receiving member 2. After that, screw in the clamp.

[0003]

[Problems to be solved by the invention] Since it is made of concrete, the weight is extremely large, so that a large amount of transportation cost is required, and since a large tow truck is used for on-site installation, the construction cost rises. there were.

In particular, there has been a problem that a great deal of labor is required to move the pressure receiving material carried to the site to change its direction.

Therefore, an object of the present invention is to provide a pressure-receiving plate which is easy to handle because it is significantly lightened.

[0006]

In order to solve the above-mentioned problems, the present invention proposes at least two hollow frustoconical pressure receiving plates having different diameters, with their open edges aligned on the same line. Further, the structure is adopted in which the through holes are overlapped with each other and the through holes are provided so as to coincide with the centers of the heads of the respective pressure receiving plates.

In addition, at least two hollow truncated pyramidal pressure receiving plates having different diameters are aligned on the same line with their release edges aligned with each other, and at the center of each pressure receiving member. This is a configuration in which matching through holes are provided.

[0008]

[Operation] Fix the tension material at the pressure receiving material arrangement position on the slope,
The pressure receiving members are sequentially arranged on the slope while the protruding end of the tensile member is passed through the through hole.

Next, the pedestal and the pressure bearing plate are sequentially fitted to the tension member projecting on the surface of the pressure receiving member, and then the fastening metal fitting is screwed in while the open edge of each pressure receiving plate of the pressure receiving member is pressed against the slope.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

(First Embodiment) As shown in FIGS. 1A and 2, at least two hollow frustoconical pressure receiving plates 11 having different diameters are provided on the same line with the open edges of the pressure receiving plates 11. The cut heads 12 are aligned and overlapped, and the overlapped cut heads 12 are fixed. The above-mentioned fixing method is performed by welding or adhesion.

A matching through hole 13 is provided at the center of each head 12.

The pressure receiving plate 11 may be made of a steel plate such as press molding or a molded synthetic resin product in which a reinforcing material such as glass fiber is embedded.

Further, in the illustrated case, two pressure receiving plates 11 having different diameters are set as one set, but three or more pressure receiving plates 11 may be set if the diameter is large or the strength is increased.

(Second Embodiment) As shown in FIG. 1b, at least two hollow truncated pyramidal pressure receiving plates 11 having different diameters are provided on the same line.
While aligning the release edges of 1 and overlapping the cutting head 12,
The overlapped head 12 is fixed.

The truncated pyramid of the pressure receiving plate 11 may be a triangular pyramid or a hexagonal pyramid instead of the illustrated quadrangular pyramid.

The overlapped heads 12 may be used without being fixed.

Next, a method of using the pressure receiving material A of the first and second embodiments configured as described above will be described.

As shown in FIG. 3, a boring hole 22 is formed in the ground from the pressure receiving material installation position on the slope 21, and a tension member 23 such as a PC steel rod is inserted into the boring hole 22 and then the boring hole 22 is inserted. An anchor body 25 is formed while injecting grout material 24 such as cement milk.

Next, the tension member 23 is passed through the through hole 13 of the pressure receiving member A carried on the slope 21 to make the tension member 23.
Of the pedestal 26 and the pressure bearing plate 27 on the portion of the pressure receiving member A protruding from the
Then, the open edges (on the back surface) of the pressure receiving plates 11 are pressed against the slopes 21 while screwing the fastening fittings 29 (nuts) into the threaded portions 28 of the tension member 23.

[0021]

As described above, according to the pressure receiving member of the present invention, since at least two hollow frustoconical pressure receiving plates having different diameters are used to form the pressure receiving member, it is possible to significantly reduce the weight.

For this reason, it is possible to carry the vehicle to the site manually without using a tow truck and to reduce the transportation cost.

Further, since the tension member is passed through the through hole of the truncated portion where the pressure receiving plates are superposed and fixed, tension can be applied even if the anchor angle is not at right angles to the pressure receiving plate.

Further, since the conical pressure receiving plate is used, the pressure receiving can be evenly distributed.

Further, since the pressure-receiving member is formed by using the pyramidal pressure-receiving plate, it is possible to arrange the pressure-receiving members with the opposite edges close to each other by using the quadrangular-pyramidal pressure-receiving plate.

Therefore, the exposed area of the soil on the slope can be reduced.
