Abstract

PROBLEM TO BE SOLVED: To prevent the metallic face of an H-shaped steel from being exposed to reduce the corrosion thereof, by erecting steel columns with an H-shaped section at every certain distance so as to oppositely arrange the opened sides and fitting the vertical grooves of square blocks forming the vertical grooves at both right and left side faces thereof, between the front flanges of the oppositely arranged H-shaped steels. SOLUTION: Steel materials 1 with an H-shaped section, provided with four projected flanges 2, are erected at every certain distance so as to oppositely arrange the opened parts. The vertical grooves 4 of a square block 3 in which the vertical grooves are formed at both right and left side faces, are fitted between the front flanges 2, 2 of the H-shaped steel 1 and then the square blocks 3 are lowered to fit to the H-shaped steels and stack up. Accordingly, the surface of the square block is not exposed to the outside and also the H- shaped steel is not exposed to rain and wind. In this way, this block wall can be easily constructed and it gives a good appearance and further, it prevents corrosion and increases durability.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a retaining block wall for easily stabilizing the ground by using a steel material, a block, or the like when revetment or sabo work is performed.

[0002]

2. Description of the Prior Art As shown in a front view of FIG. 7 and a cross-sectional plan view of FIG. Between,
The walls were constructed by fitting concrete flat plates and sequentially stacking them.

[0003]

The above-mentioned conventional earth retaining block wall is constituted by fitting concrete flat plates between H-shaped steel flange pieces and successively stacking them. The metal surface can be seen and it is not preferable from the viewpoint of the scenery, and there has been a problem that the metal surface is rusted and corroded over a long period of time, losing strength and collapsing.

[0004]

SUMMARY OF THE INVENTION The present invention has been proposed to solve the above-mentioned inconvenience, and has a structure in which an H-section steel is provided upright at a predetermined interval with open portions opposed to each other. A vertical groove is formed on the left and right side surfaces of the rectangular block, and the vertical groove is fitted between opposed front flange pieces of the H-shaped steel.

[0005]

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be described in detail with reference to the drawings. 1 to 3 show an earth retaining block wall according to the present invention, in which 1 is an H-section steel, and four flange pieces 2 protrude. Such an H-section steel 1 is erected at regular intervals with its open portions facing each other. Reference numeral 3 denotes a concrete block used in the present invention, which is formed of ordinary concrete, foamed concrete, porous concrete mixed with lightweight aggregate, and the like. Numerals 4 are vertical grooves formed on both side surfaces of the block 3. When the vertical grooves 4 are made of low-strength concrete such as foam concrete or porous concrete, the vertical grooves 4 are reinforced by a metal plate, a synthetic resin plate, FRP or the like. The plate 5 is integrally covered and reinforced.

According to the present invention, the rear portion of the block 3 is fitted to the open portions of the front and rear flange pieces 2 and 2 of the H-section steel 1 in which the open portions of the H-section steel 1 are opposed to each other with a predetermined interval therebetween. Then
At the same time, the front flange piece 2 of the H-section steel 1 is fitted, the block is lowered, and the blocks 3 are sequentially fitted with the H-section steel 1 and stacked.

[0007]

According to the present invention, as described above, the vertical grooves 4 provided at both ends of the block are sequentially fitted between the flange pieces 2 and 2 behind the opposed H-section steel 1. Since it is repeatedly piled up, it can be easily constructed, the surface of the block is graceful without being exposed to the outside, and the block has flutes 4 on both sides.
, So that it forms a strong wall without sneaking out. In addition, the H-section steel 1 exhibits effects such as being less exposed to wind and rain, less corrosive and enduring long-term use.

When the block 3 is formed of foamed concrete, porous concrete mixed with lightweight aggregate, or the like, the water contained in the embankment on the back of the wall will not be covered by the block 3.
It penetrates inside and is discharged from the front, plants such as moss easily grow on the surface, and seeds adhere to the surface of the wall,
It is covered by germinated plants and forms a natural environment. In addition, the surface of the block is formed into a pseudo-stone shape, as if natural stones are piled up, and the space between the pseudo-stones is filled with earth and sand, whereby plants grow and become a natural environment.

If the left and right sides of the block 3 and the outer periphery of the vertical groove 4 are integrally covered with a reinforcing plate 5 made of a metal plate, a synthetic resin plate, FRP or the like, the portion is reinforced and the end of the block 3 is damaged. Is prevented.
