Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a legal frame block, and more particularly to a legal frame block used in a method of combining geotextile and legal frame work.

[0002]

2. Description of the Related Art In a method of combining geotextiles and frame construction, embankment construction is carried out while sandwiching the geotextile, and after the slope shape is finished, a frame block is laid on the slope to end the geotextile. The geotextiles are fixed to the legal block by sandwiching them between the upper and lower edges of the legal frame.

[0003]

[Problems to be Solved by the Invention] In this construction method,
The slope block cannot be laid unless the slope shape is finished. In addition, because the geotextile will be connected to the law block with the geotextile already installed inside the embankment, it is not possible to give sufficient tension to the geotextile, and therefore the reinforcement effect of the geotextile can be fully exerted. There was a problem that I could not do it.

Further, since the conventional slope frame block is simply laid on the slope, it is suitable when the slope is gentle, but when it is steep, there is a risk of collapse due to earth pressure. It is highly likely.

The present invention solves the above problems, and can be installed without waiting for the finish of the slope shape, so that tension can be easily applied to the geotextile and a steep slope method can be applied. The object is to provide a legal block that can be easily installed even on a surface.

Another object of the present invention is to provide a legal block which can maintain a good landscape on the slope.

[0007]

In order to achieve the above-mentioned object, the present invention is directed to a bottom plate, a vertical piece integrated with the back surface of the bottom plate, and a top surface of the vertical piece parallel to the bottom plate. And a pair of side plates which are integrated by connecting both sides of the back plate and both sides of the bottom plate and whose end faces are inclined at a predetermined slope. It provides a frame block.

In the method frame block of the present invention, it is preferable that the vertical piece of the back plate and the side plate have communication holes formed therein.

Further, the horizontal piece of the back plate and the bottom surface of the bottom plate may be provided with positioning and fixing projections and recesses that engage with each other in a state where the above-mentioned method frame blocks are stacked vertically. Furthermore, bolt insertion holes may be formed in the horizontal piece of the rear plate and the bottom plate so as to coincide with each other in a state where the legal frame blocks are vertically stacked.

[0010]

[Advantage] According to the above configuration, if the bottom plate is installed with the back plate facing the embankment construction side and arranged in a line, and then the embankment is constructed inside the partition, the A slope is formed according to the inclination of the side plate on the front side. Then, lay the geotextile on the surface of the embankment, place the terminal on the top surface of the horizontal piece of the method frame block, and install the bottom plate of the next method frame block on the top of the horizontal piece. It is easily fixed in the state that it is sandwiched between the legal frame blocks.

After that, if the embankment, geotextile laying, and installation of the method frame block are alternately repeated up to a predetermined height in the same manner as described above, a slope having a slope corresponding to the inclination of the side plate of the method frame block can be formed simultaneously with the embankment formation. .

At this time, since the positioning and fixing irregularities are provided on the upper and lower sides of the method frame block in advance, the positioning at the time of stacking work is easy, and the connection strength between the method frame blocks after stacking is also improved. In addition to this, if a bolt insertion hole is provided in the horizontal piece and the bottom plate, the upper and lower method frame blocks can be connected by a bolt nut.

Further, the inner space surrounded by the bottom plate, the back plate and the both side plates of the legal frame block can be filled with soil and used for vegetation. In addition, by opening communication holes in the back plate and the side plate, free water can be passed and used for rooting vegetation.

[0014]

Embodiments of the present invention will now be described in detail with reference to the drawings. 1 to 4 show a first embodiment of the present invention. In the figure, a method frame block 10 is made of precast concrete, and includes a bottom plate 12 and a bottom plate 1.
Vertical piece 14a and vertical piece 14 integrated on the back surface of
a rear plate 14 in which an L-shaped horizontal piece 14b extending from the top front surface of a to the bottom plate 12 is formed, and both sides of the back plate 14 and both sides of the bottom plate 12 are connected and integrated, and the end face is It is composed of a pair of side plates 16 that are inclined at a predetermined gradient.

Communication holes 18 and 20 are formed in the vertical piece 14a and the side plates 16 so as to penetrate through the plate in the thickness direction. The communication holes 18 and 20 are provided to allow free water to flow in and out and to secure rooting of vegetation.

A plurality of engaging concave portions 22 are formed on the top surface of the horizontal piece 14b at predetermined intervals, and a pair of engaging convex portions are formed on the lower surface of the bottom plate 12 at positions corresponding to the concave portions 22. 24 is formed to project. The engaging concave portions and the convex portions 22 and 24 are used for positioning and fixing when the method frame blocks 10 are stacked.

Next, a method of constructing an embankment using the method frame block 10 having the above structure will be described with reference to FIGS. First, the rear plate 14 is first turned to the embankment construction side, and the bottom plate 12
Is installed to arrange the legal frame blocks 10 in a horizontal row, and then the embankment E is applied to the inside partitioned by the legal frame blocks 10 to form a slope corresponding to the inclination of the front surface of the side plate 16.

After that, the geotextile 26 is laid on the surface of the embankment E, and the terminal 26a is positioned on the top surface of the horizontal piece 14b.
If the bottom plate 12 of 0 is installed, the terminal 26a of the geotextile 26 is fixed in a state of being sandwiched between the upper and lower method frame blocks 10. At this time, if the upper side slope block 10 is installed at a position retracted along the slope determined by the inclination of the end face of the side plate 16, the slope slope continues. At this time, the installation positioning and the fixing are performed by fitting the engaging convex portion 24 provided on the bottom plate 12 of the upper side frame block 10 into the engaging concave portion 22 formed on the horizontal piece 14b of the lower side frame block 10. By this, positioning and connection and fixing are completed at the same time, and strong stacking is possible.

After that, if the embankment E, the geotextile 26 are laid and the method frame block 10 is alternately installed up to a predetermined height in the same manner as described above, as shown in FIG. A slope having a slope corresponding to the inclination of the face plate 16 on the front surface side can be formed.

When stacking the method frame blocks 10, they may be stacked in a grid pattern as shown in FIG. 4 (a), or may be stacked in a staggered pattern as in bricks as shown in FIG. 4 (b). It is also possible to use any of the stacking methods, and the engaging convex portion 24 is fitted into the engaging concave portion 22 and is positioned and fixed.

After the above construction is completed, each legal block 10
The inner space surrounded by the bottom plate 12, the back plate 14 and the side plates 16 of the above can be used for the vegetation 28 if filled with the soil G.
Further, the communication hole 1 opened in the back plate 14 and the side plate 16
Nos. 8 and 20 allow free water to flow in and out, and vegetation 28
Since it can be used for rooting, it is possible to plant not only flat vegetation such as lawn turf, but also vegetation that requires rooting such as vegetation. In this case, rooting through the communication holes 18 and 20 is possible. Reaches the inside of the embankment E while being intricately entangled with each other and connects between the slope frame blocks 10, so that the slope strength can be further increased.

5 and 6 show a second embodiment of the present invention. It should be noted that the same parts as those in the above-mentioned embodiment in the drawing are denoted by the same reference numerals, and only newly added parts will be described by using different reference numerals.

In the figure, the horizontal plate 14b of the rear plate 14 is shown.
A pair of bolt insertion holes 4 are formed in the bottom plate 12 and the bottom plate 12 so as to be aligned with each other in a state in which the method frame blocks 10 are vertically stacked.
Openings 0 and 42 are formed.

Therefore, in this embodiment, the bolts 44 and the nuts 46 can be connected between the upper and lower legal frame blocks 10, and the terminal 26a of the geotextile 26 can be simply squeezed in as well as the rigid connection between the legal frame blocks 10. In addition, since the bolt 36 can be securely fixed by penetrating the geotextile 26 in the upper and lower directions, it is possible to obtain a stronger slope reinforcement effect.

In each of the embodiments, since the bottom plate 12 of the first frame block 10 was installed horizontally at the time of construction, the slope of the side plates 16 is set according to the inclination of the side plates 16. If you want to make a gradient, if you set the first law frame block 10 in a slightly rearward tilted posture, it will become a gentle gradient, and if you want to make a steep gradient, the first law frame block 1
If 0 is installed in a forward leaning posture, a steep slope will result. Further, when it is desired to change the inclination on the way, a method frame block having a side plate having an inclination angle corresponding to the inclination can be prepared.

[0026]

As described above in detail with reference to the embodiments, the legal frame block according to the present invention has the following advantages. If the bottom plate is installed with the back plate facing the embankment construction side and arranged in a line, and then embankment is applied inside the partition of the method frame block, the method according to the inclination of the side plate in front of the method frame block Since the surface is formed, the work such as measuring the height of the embankment and setting the slope is unnecessary, and the construction is simplified. After constructing the embankment of each height, lay the geotextile on the surface of the embankment, and with the terminal positioned on the top surface of the horizontal piece of the legal frame block, install the bottom plate of the next legal block on top of the horizontal piece. , If installed in a state where it is retracted along the slope determined by the inclination of the side plate, the geotextile terminal is fixed while being sandwiched between the upper and lower framing blocks, so it is possible to lay it with tension on the geotextile. The reinforcement effect of the embankment is high. In this case, if the positioning and fixing irregularities are provided in advance on the upper and lower sides of the method frame block, the positioning at the time of stacking work is easy, and the connection strength between the method frame blocks after stacking is also improved. In addition to this, by forming a bolt insertion hole, you can connect the upper and lower method frame blocks with bolts and nuts, further increasing the bonding strength between the method frame blocks and fixing the geotextile terminal. Also becomes reliable, and the reinforcing effect can be improved. Since the slope block is self-supporting, there is no risk of collapse even if it is a steep slope, and therefore it is particularly suitable for the construction of an embankment having a steep slope. The inner space surrounded by the bottom plate, back plate and both side plates can be filled with vegetation and used for vegetation.By opening communication holes in the back plate and side plates, free water can come and go and vegetation Since it can be used for rooting, not only vegetation with flatness such as lawns but also vegetation can be vegetated, and vegetation landscape after embankment construction can be freely created according to the purpose and application.
