Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressure receiving structure fixed to a slope by anchor bolts for stabilizing the slope.

[0002]

2. Description of the Related Art In recent years, a block made of precast concrete has been used as a pressure receiving structure for bearing the load of soil on the slope to stabilize the slope, and the pressure receiving structure is inserted into an anchor bolt fixed to the ground on the slope to form an anchor bolt. A method in which a nut is screwed into the projecting end and tightened to fix is adopted, and there is also known a method in which a pressure receiving plate made of glass fiber reinforced urethane (FFU) is used instead of the concrete block in order to reduce the weight.

Other known methods for stabilizing the slope include a method for constructing a slope by placing concrete on the slope and a method for constructing a slope by installing a factory-produced concrete block on the slope. To be

[0004]

In the construction method in which the slope is installed on the slope, it is possible to vegetate and grow greenery inside the slope, but the slope is constructed by placing concrete on the slope. The construction method requires installing a formwork on the slope and assembling the reinforcing bars and placing concrete, which makes the work complicated and the work efficiency is poor, and the construction is difficult especially on a steep slope. Although the method of installing the concrete block on the slope is more efficient than the above method, it takes a lot of time and effort to assemble and fix the concrete block on the slope.

On the other hand, the pressure receiving structure can be fixed simply by mounting it on one anchor bolt and tightening the nut screwed into the protruding end thereof, so that the work efficiency at the time of construction is better than that of the above construction method, and the comparison is made. It is possible to receive the earth and sand load on the slope over a large area, but the slope with the pressure receiving structure has a problem in the landscape. An object of the present invention is to provide a pressure receiving structure that can improve the landscape by greening.

[0006]

According to a first aspect of the present invention, a pressure receiving structure in the form of a grid, which is composed of vertical rails and horizontal rails, is inserted into an anchor bolt fixed to the ground on the slope, and then the pressure receiving structure is pressed onto it. It is a pressure receiving structure in which the plates are inserted and stacked, and then the protruding end of the anchor bolt protruding from the holding plate is screwed and fixed by tightening the nut, and the pressure applied when the holding plate is screwed in and tightens the nut. It is characterized in that it is dispersed in the pressure receiving structure and vegetation is made through the squares composed of vertical and horizontal rails.

According to the pressure receiving structure of the present invention,
The scenery can be improved and the nut can be screwed in and tightened.
Make sure that the pressure force during tightening when installing and fixing is dispersed.
By pressing, the pressure-receiving structure is
Can be set.

The pressure receiving structure of the present invention can be used alone or in a plurality of layers. When stacking a plurality of cells, the squares of each pressure receiving structure may have the same size or different sizes. In any case, the pressure receiving structure to be stacked is such that the squares are not blocked by the vertical and horizontal bars of the lower and / or upper pressure receiving structure, or even if they are partially blocked. Are taken into consideration so that they will be reduced. The pressure receiving structure may also be made of steel, but is preferably made of FRP for weight reduction.

The invention according to claim 2 is characterized in that, in the invention according to claim 1, shaped steels combined in a cross shape or a cross shape are used instead of the pressing plate. According to the present invention, since the shaped steel has high rigidity, a concentrated load can be applied by the anchor bolts, and even if the concentrated load is large, the pressure receiving structure can be strongly and uniformly pressed.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION In FIG. 1, three pressure receiving structures 1, 2 and 3 having sizes different from large, medium and small are all FRP.
It is made of a vertical cross and a horizontal cross, and the squares are the same size. The vertical rail and the horizontal rail are cut into a cross shape to pass an anchor bolt described later in the center.

At the time of fixing, as shown in FIG. 2, anchor bolts 5 are fixed to the ground 4 on the slope, and the pressure-receiving structures 1, 2 and 3 are cut off from the protruding portion in order of increasing size. The pressure receiving structures 1, 2 and 3 are tightened and fixed to the slope by inserting the press-fitting plate 6 on the part and screwing the cap nut 7 at the protruding end of the bolt.

According to the pressure-receiving structure of the present embodiment, each pressure-receiving structure is made of FRP and has a lattice shape, which is lightweight.
It is easy to transport, and at the time of construction, just insert the pressure receiving structure one by one into the anchor bolt, insert the holding plate at the end, and screw the cap nut into the protruding end of the bolt to perform the installation work. The work efficiency is improved, the load on the entire pressure-receiving structure can be received substantially, and the grid-like structure enables stable mounting even if there is some unevenness on the slope. By providing the pressure receiving structure, the pressure receiving structure can be firmly fixed, vegetation can be performed through the lattice-shaped pressure receiving structure, and the landscape can be improved by greening.

FIG. 3 shows vegetated pressure receiving structures 1, 2 and 3
9 shows the overgrown weeds. In the above embodiment, the pressure receiving structures 1, 2 and 3 have different sizes, but in other embodiments, the same size is used. In the above embodiment, the pressing plate is also used to press the pressure receiving structure, but in another embodiment, shaped steel is used. FIG. 4 shows an example in which the H-shaped steel is combined with a cloth and the pressure receiving structure 11 is pressed down.

FIG. 5 is a sectional view of the pressure plate 12 at four corners. The pressure receiving structures 1 and 2 each have a cross section having the same shape and size as the grid of the lattice formed by the vertical and horizontal bars of the pressure receiving structure. 3 shows an example in which a leg 13 having the same thickness as that of No. 3 is provided in a protruding manner. According to this embodiment, by inserting the legs 13 into the pressure receiving structures 1, 2, and 3, the squares of the pressure receiving structures are aligned.

[0015]

According to the invention of claim 1, since the pressure receiving structure has a lattice shape, the pressure receiving structure is lightweight and easy to carry, and the pressure receiving structure is inserted into one anchor bolt at the time of construction, and the projecting end of the bolt is It is only necessary to screw in the nuts for tightening work, improving work efficiency, being able to receive earth and sand loads substantially over the entire pressure-receiving structure, and having a grid-like structure, there is some unevenness on the slope. Even if there is, it can be installed stably, the landscape can be improved by greening , and the stress distribution is performed by the holding plate.
The entire pressure plate to hold the pressure receiving structure firmly.
The effects such as being able to achieve are achieved.

According to the shaped steel of the second aspect of the present invention, since the rigidity is high, when the anchor bolt is used for tightening, the pressure-receiving structure can be strongly pressed by the entire shaped steel with a uniform pressing force.
