Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building block, and more particularly to a building block suitable for revetment work on rivers and coasts.

[0002]

2. Description of the Related Art Conventionally, as a building block used for revetment work for rivers, roads, etc., a block made of concrete and having the skin of the concrete exposed is generally used. Recently, however, environmental protection has come to be emphasized, and harmony with nature has come to be required even in revetments of rivers and roads. For this reason, in order to express the natural state on the surface of the revetment, there has been an appearance in which a natural stone is held on the surface of the revetment by using a "gabion" which has been used for a long time.

[0003]

[Problems to be Solved by the Invention] However, the original purpose of the revetment is to protect the slopes of rivers and roads from collapsing during flooding or heavy rain, as well as the landscape of the slope surface. On the other hand, in the old Jabiko, there was a point where the concrete block was taken a step further in terms of the strength of the revetment. In addition, the traditional gabion is currently the situation that there are almost no craftsmen who can manufacture or construct it, and it is not possible to meet the demand, so the construction cost is high and the construction period is long.
There was a problem. Therefore, it is an object of the present invention to provide a construction block especially for a seawall, which has sufficient strength of a concrete block and also has an advantage of a gabion that can be harmonized with nature, especially rivers.

[0004]

In order to solve the above-mentioned problems, a construction block according to the present invention comprises a block frame body made of concrete and having reinforcing bar insertion holes on the left and right, and the block frame made of a natural material. A cage frame formed of a decoration material provided inside the body and a wire made of metal, synthetic resin, or the like and covering the outer surfaces of the front and back sides of the decoration material and the ends of the wire material fixed to the block frame body. And a member.

[0005]

According to the present invention having the above structure, the construction block frame body is made of hollow concrete, and since the rebar insertion holes are provided on the left and right inside the frame body, the construction block frame body is constructed. In addition to being able to integrate the entire block and having sufficient strength as a revetment, a gabion is formed on the surface of the block to hold the decorative material. Plants and seafood can flourish 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 the configuration of a construction block which is an embodiment of the present invention.

As shown in FIG. 1, this building block 1
Is a block frame body 2 and a large number of boulders 3 which are decorative materials,
The front side cage frame member 4U is provided on the front surface side of the block, and the back side cage frame member 4L is provided on the back side of the block.

The block frame body 2 is a hollow frame-shaped frame block in which upper and lower horizontal portions and right and left vertical portions are integrally molded with concrete.
It has one rebar insertion hole 21, 21 in the vertical direction. Each rebar insertion hole 21 is a substantially pipe-shaped member formed by placing concrete into a tubular shape with a thickness of about 3 cm, and is arranged at a position of a length of 1/4 from the side edge of the block frame body 2. Has been done. In addition, a semi-cylindrical convex portion 22 is provided in the upper lateral portion of the block frame 2, a semi-cylindrical groove portion 23 is provided in the lower lateral portion, and a semi-circular portion is provided in the left and right vertical portions. Columnar groove portions 24, 24 are provided. As the reinforcing bar insertion hole 21, a pipe material made of synthetic resin, metal or the like may be used, and the pipe material may be housed inside the mold when the block frame body 2 is molded.

The front side cage frame member 4U and the back side cage frame member 4
The L is formed by a steel wire 41 in the shape of a slightly coarse mesh basket, and is attached so as to cover the front surface side and the back surface side of a large number of cobblestones 3 which are decorative materials made of natural materials. This number 41
42 is fixed in the concrete of the block frame 2. Further, between the mesh nodes of the front side cage frame member 4U and the back side cage frame member 4L, the boulders in the cage frame member do not shift to one side during transportation or during slope construction or after construction. In addition, a tightening wire 43 is attached to reinforce the front side cage frame member and the back side cage frame member.

A construction method and its structure for constructing a slope of a river bank or a road using the construction block 1 of the present invention will be described with reference to FIG. As shown in the drawing, the front side cage frame member 4U or the back side cage frame member 4L side is the front side of the slope, and the blocks 1 are laid along the slope. At this time, the ridges 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 ridges 22 in the upper and lower blocks 1.

In this case, the blocks 1 are stacked, but the left and right reinforcing bar insertion holes 21 are provided in the longitudinal direction at a position of a length of 1/4 from the side edge, so that the blocks are clothed. Reinforcing bar insertion holes 21 of upper and lower blocks 1 even in the stacked state
Communicate with each other. Therefore, if the vertical reinforcing bars 10 are inserted in series in the reinforcing bar insertion holes 21 communicating in the vertical direction, and if necessary, the filling concrete 11 is filled, the stacked building blocks 1 are integrated as a whole, and external force such as an earthquake is applied. It also becomes possible to counter, and develops sufficient strength as a seawall. In addition, the adjacent groove portions 2 are provided between the adjacent blocks.
A space having a substantially cylindrical shape is formed by the four members, and the filling concrete 12 can be placed in this space to fix each block.
