[0002]

2. Description of the Related Art Conventionally, as a construction block used for revetment work on rivers and roads, a construction block made of concrete and having a surface of concrete exposed on the surface is generally used. Recently, however, the importance of environmental protection has been emphasized, and the protection of rivers and roads has to be in harmony with nature. For this reason, in order to express the natural state on the revetment surface, there has been appeared one in which natural stones are retained on the revetment surface using a "gabion" which has been used for a long time.

[0003]

However, the original purpose of revetment works is to protect the slopes of rivers and roads so that they do not collapse when the rivers rise or heavy rains, in addition to the landscape of the slopes. In that regard, the traditional gabion had a step in the concrete block in terms of seawall strength. In addition, the old gabion is currently the only place where there are few craftsmen who can manufacture and construct it, and can not respond to demand, so the construction cost is high and the construction period is long,
There was a problem. Therefore, an object of the present invention is to provide a building block, particularly for seawalls, which has the strength of a concrete block and also has the advantages of a gabion that can be harmonized with nature, particularly a river.

[0004]

In order to solve the above-mentioned problems, a building block according to the present invention has a frame shape in which upper and lower horizontal portions and left and right vertical portions are integrally formed of concrete, and has a hollow interior. A block frame body provided with left and right rebar insertion holes substantially made of a pipe-shaped member, a decorative material made of a natural material and provided inside the block frame body, and a wire made of metal or synthetic resin or the like. A basket frame member covering the front and back outer surfaces of the decorative material and having the ends of the wire rod fixed to the block frame body, and a tightening number line for reinforcing the front basket frame member and the back basket frame member. It is characterized by having.

[0005]

According to the present invention having the above construction, the construction block frame is made of hollow concrete, and the inside of the frame is provided with reinforcing bar insertion holes on the left and right sides, so that it is constructed for revetment. The entire block can be integrated, not only has sufficient strength as a revetment, but also a gabion is formed on the surface of the block and the decoration material is held, so the decoration material surface and between the decoration materials Plants and seafood can thrive in the gaps, and insects can also inhabit.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing a configuration of a building block according to one embodiment of the present invention.

[0007] As shown in FIG.
Is a block frame 2, a large number of cobblestones 3 as decorative materials,
The front basket frame member 4U provided on the front side of the block and the back basket frame member 4L provided on the back side of the block are provided.

The block frame 2 is a hollow frame-shaped frame block in which the upper and lower horizontal portions and the left and right vertical portions are integrally formed of concrete.
It has two rebar insertion holes 21 and 21 in the vertical direction. Each rebar insertion hole 21 is a substantially pipe-shaped member formed by casting concrete into a tube having a thickness of about 3 cm, and is disposed at a position 1/4 the length from the side edge of the block frame 2. Have been. Further, a semi-cylindrical ridge 22 is provided in the upper horizontal portion of the block frame 2, a semi-cylindrical groove 23 is provided in the lower horizontal portion, and semi-circular portions are provided in the left and right vertical portions. Column-shaped grooves 24 are provided. The rebar insertion hole 21 may be formed by using a pipe material made of synthetic resin, metal, or the like, and storing the pipe material inside the mold when the block frame 2 is formed.

The front basket frame member 4U and the back basket frame member 4
L is formed in an iron wire line 41 in a slightly coarse mesh cage shape, and is attached so as to cover the front side and the back side of a large number of boulders 3 which are decorative materials made of a natural material. This track 41
Is fixed in the concrete of the block frame 2. In addition, between the nodes of the meshes of the front side basket frame member 4U and the back side basket frame member 4L, the cobblestone in the basket frame member is not deviated to one side during transportation or during slope construction or after construction. Further, a fastening line 43 is attached to reinforce the front basket frame member and the back basket frame member.

Referring to FIG. 2, a construction method and a construction method in the case of constructing a slope such as a revetment of a river or a road by using the construction block 1 of the present invention will be described. As shown in the figure, the front side basket frame member 4U or the back side basket frame member 4L is set as the front side of the slope, and the blocks 1 are laid along the slope. At this time, the protrusions 22 provided on the upper surface of the block frame 2 are stacked so as to face upward, and the blocks 1 are stacked so that the grooves 23 are aligned with the protrusions 22 in the upper and lower blocks 1.

In this case, the blocks 1 are stacked, but the left and right rebar insertion holes 21 are provided in the vertical direction at a position 1/4 the length from the side edge, so that the blocks 1 are stacked. Even in the stacked state, the reinforcing bar insertion holes 21 of the upper and lower blocks 1
They communicate with each other. Therefore, when the vertical reinforcing bars 10 are inserted in series into the reinforcing bar insertion holes 21 communicating in the vertical direction, and if necessary, the concrete filling 11 is filled, the stacked building blocks 1 as a whole are integrated, and an external force such as an earthquake is generated. And develop sufficient strength as revetment. In addition, between adjacent blocks, adjacent grooves 2
A substantially cylindrical space is formed between the four members, and each block can be fixed by pouring the filling concrete 12 into this space.
