Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an earth retaining work (also referred to as an earth retaining work structure or an earth retaining device) and a frame device suitable for use therein.

[0002]

2. Description of the Related Art Soil retaining works are generally constructed for the purpose of preventing soil on an inclined surface from flowing. The simplest structure is to drive piles into the ground at appropriate intervals. , The shield holds the shielding plate made of metal plate or the like so as not to fall down.

On the other hand, flower beds are widely provided in parks, roads, plazas, gardens of public facilities, gardens of private houses, etc. In this case, when the planting surface is set higher than the ground, , Plant flowers that can be carried around and plant flowers on them, or plant flowers on the ground by incorporating soil into a planting frame that is composed of concrete blocks.

[0004]

[Problems to be Solved by the Invention] The conventional earth retaining work is
Only the purpose of preventing the outflow of soil is focused, and the piles and the metal shielding material are bare in most cases, so that there is a drawback that the appearance is inferior.

In addition, in the case where a flower bed of a planting surface higher than the ground is provided in a park or a road, the conventional method of simply installing a planter or a concrete planting frame is different from the conventional method. In many cases, the appearance of the planting frame and the planting frame are exposed as it is, so the aesthetics could not be improved.

On the other hand, although retaining walls are ubiquitous in Japan, this retaining wall is generally constructed by inter-block block stacking or concrete pouring, and in any case, it has a white appearance that stands out from the surroundings. Therefore, it has been pointed out that it is damaging the landscape.

As one of the measures for improving the landscape of this retaining wall,
It is conceivable to plant plants such as flowers on the retaining wall to make them green. Regarding this point, it is possible to install a planter on the ground of the retaining wall and plant flowers etc.
This has the drawback of not only saving space, but not exposing the appearance of the planter as it is, which does not improve the aesthetics.

The present invention has been made for the purpose of improving the present situation.

[0009]

The present invention includes an earth retaining work and a frame device suitable for the same. The earth retaining work is, as described in claim 1, between a decorative material forming the outer wall surface of the earth retaining portion and the soil between the decorative material for preventing the decorative material from coming into contact with the soil. The shielding material is arranged, and the decorative material is detachably fixed to the shielding material or a support metal fitting arranged outside the shielding material.

On the other hand, in the frame device, as described in claim 2, the decorative material arranged in the shape of a wall or a fence, the shielding material arranged inside the decorative material, and the shielding material for the decorative material or the same. Fixing means for detachably fixing to a support metal piece arranged outside is provided.

[0011] Claim 3 shows a preferred embodiment of the earth retaining work and the frame device. In the present invention, the decorative material is
It is made up of many timbers such as thinned wood and barrel boards.These timbers are the main decorative wood groups that are laid sideways and stacked in multiple stages, and the ends of the main decorative wood groups. It is configured to be separated from the vertically long decorative decorative wood that overlaps from the outside.

On the other hand, the support fitting is composed of a pair of inner and outer fittings for sandwiching the ends of the multi-tiered timber group, and the fastening means is composed of a bolt and a nut. The main decorative wood group, the pressing wood, and the inner and outer fittings are fastened together by pulling the decorative wood for use and the inner fitting together with bolts and nuts.

The earth retaining work according to the present invention does not have to be for preventing the soil on the inclined surface from flowing, and can be used as a planting device for cultivating plants such as flowers. You can also Further, the shielding material only needs to have a function of preventing contact between the soil and the decorative material, and does not necessarily require strength. Therefore, it may be made of a soft material such as a resin sheet or a rubber sheet.

[0014]

According to the present invention, since the appearance of the earth retaining work is covered with the decorative material, the aesthetic feeling (landscape) can be significantly improved. Moreover, since the cosmetic material can be removed, if the cosmetic material is corroded or damaged, only the cosmetic material can be replaced without impairing the soil retaining function, which facilitates maintenance.

When applied to a retaining wall, a frame device is installed in parallel with the retaining wall, and soil is put between the frame device and the retaining wall, so that a plant The growth department can be easily built, and the greening of the retaining wall can be promoted. Further, by arranging the frame device annularly in a plan view,
By pouring the soil into the inside surrounded by the frame device, it is possible to easily build flower beds whose planting surface is higher than the ground in any place such as a park or a road.

As described above, when a planting section is constructed on the retaining wall or flower beds are constructed on a park or a road, the outer surface of the frame device is dressed with a cosmetic material, which is excellent in beauty. .

By the way, in the mountain forests of Japan, artificial forests that have been planted but have not been thinned reach a large area. It has seriously affected people living in the downstream and fisheries by causing devastation and frequent floods, and promotion of thinning has become an urgent task for national land conservation measures. And the reason why thinning has not progressed so far is that thinned wood has little economic value.

On the other hand, as the decorative material of the present invention, it is preferable to use wood because of its unique warmth. And
Since the thinned wood has a diameter of about 10 cm and a thickness suitable for the decorative material of the present invention, the earth retaining work and the frame device according to the present invention give the thinned wood an economic value and greatly contribute to the promotion of the thinning. However, it is expected that it will contribute much to national land conservation.

[0019]

Embodiments of the present invention will now be described with reference to the drawings.

In the drawings, the growing section 5 is shown only with soil, but it goes without saying that a multi-layered structure may be used, such as providing a permeable layer made of stones of different grain sizes at the bottom.

The frame device 4 comprises a keystone plate (folding plate) 6 made of a metal plate and bent in an uneven cross section, and a pair of inner and outer supporting metal fittings 7, 8 arranged at appropriate intervals on the outer side thereof.
And a main decorative wood group 9 which is stacked in multiple layers in a laid state and whose ends are sandwiched by inner and outer metal fittings 7 and 8, and a vertically long decorative decorative wood which overlaps the ends of the main decorative wood group 9 from the outside, The top decorative wood 11 that overlaps the upper end of the main decorative wood group 9 and the upper end of the pressing decorative wood 10, a pressing bolt (double-cutting bolt) 12 and a pressing nut 13 for joint tightening are provided.

The keystone plate 6 is an example of a shielding material (water impervious material) that prevents the soil and the decorative wood groups 9 and 10 from coming into contact with each other. From the viewpoint of rust prevention, a stainless steel plate or a plated steel plate is used. Preferably. In the present embodiment, the keystone plate 6 is arranged so as to be uneven in a side cross-sectional view, but it is also possible to arrange the keystone plate 6 in a posture where it is uneven in a plan view. The lower end of the keystone plate 6 is in contact with the ground 15.

The keystone plate 6 does not necessarily have to be used as the earth shielding material, and synthetic resin molded products, concrete molded products, ceramic-based plate materials similar to siding materials for houses, slate plates, water-impermeable soft sheets, etc. It is also possible to use those made of various materials. of course,
It is also possible to use a metal flat plate (this point is the same in other embodiments).

Main decorative wood group 9, pressing decorative wood 10 and sky decorative wood 11 as examples of decorative materials are cedar, Japanese cypress,
It is preferable to use various types of thinned wood such as pine and hemlock as the material, and cut it into a semi-cylindrical shape so that it will exactly overlap when stacked (of course, it is more natural using mere logs) It is also possible to reveal the state).

The main decorative wood groups 9 are arranged in the horizontal direction at a slight interval, and two adjacent main decorative wood groups 9 are provided.
One press decorative wood piece 10 is overlaid on the end of each of them, and press bolts 12 and press nuts 1 are arranged at appropriate intervals in the vertical direction.
By attracting the inner metal fitting 7 and the pressing decorative wood 10 at 3, the inner and outer metal fittings 7, 8 and the main decorative wood group 9 and the pressing decorative wood 10 are fastened together.

Therefore, a large number of main decorative wood groups 9 can be fixed or unfixed at a time with a small number of holding bolts 12, and the labor for construction and maintenance can be reduced.

The left and right lengths of the keystone plate 6 are set to be the same as the left and right lengths of the main decorative wood group 9 (that is, the main decorative wood group 9 and the keystone plate 6 are unitized). As shown, the gap between the adjacent keystone plates 6 is closed by a water-blocking sheet 16 as an example of sealing means. The water-blocking sheet 16 is flexible and waterproof.

.. Structural Details The inner metal fitting 7 is fixed to the retaining wall 1 by anchor bolts 18, whereby the frame device 4 is held in a vertical posture. Hereinafter, details of the frame device will be described with reference to the drawings starting from FIG.

FIG. 4 is an exploded perspective view of the upper portion of the frame device 4, FIG.
6 is a perspective view of the lower part of the frame device 4, FIG. 6 is a plan sectional view of the same portion as FIG. 2, FIG. 7 is a sectional view taken along line VII-VII of FIG. 1, and FIG. 8 is a plan view of the end portion of the earth retaining work 3. Sectional view, Figure 9 is IX-IX in Figure 8
FIG.

For example, as can be easily understood from FIG.
Inner and outer metal fittings 7 and 8 are protrusions 1 protruding in opposite directions.
9 is formed symmetrically and has both metal fittings 7,
Both 8 are provided with a vertical groove (long groove hole) 20 extending long vertically. Both the metal fittings 7 and 8 are preferably made of a metal plate having a high degree of rust prevention such as a stainless steel plate.

In this embodiment, both the inner and outer metal fittings 7 and 8 are
Since the two plates are manufactured by using the two plates as materials, the two metal plates are connected (welded) by a plurality of rectangular tube-shaped connecting members 21 which are vertically arranged at appropriate intervals. Connecting member 21
Are provided at the same height in the inner and outer metal fittings 7 and 8 (in this embodiment, three locations of the upper portion, the lower portion and the upper and lower intermediate portions). It is stuck.

Then, the connecting member 21 of the outer metal fitting 8 and the decorative decorative wood 10 are fitted into the two-sided press bolt 12 screwed into the high nut 22, and the press nut (cap nut) 13 is screwed into the exposed portion of the press bolt 12. By doing so, the inner and outer metal fittings 8, the main decorative wood group 9, and the decorative decorative wood 1
We are tightening together with 0.

The main decorative wood group 9 is positioned by the projections 19 of the inner and outer metal fittings 8. The high nut 22 is the holding bolt 1
It is also fixed to the inner fitting 7 by a bolt 23 screwed in from the side opposite to 2.

As shown in FIG. 5, at the lower end of the inner metal fitting 7,

By fixing with, a slight gap is provided between the lower end of the main decorative wood group 9 and the ground.

Since there is a gap between the main decorative wood group 9 and the ground in this way, the main decorative wood group 9 can be aligned and arranged irrespective of the unevenness of the ground.
The durability can be improved by preventing or suppressing the main decorative wood group 9 from getting wet with rainwater flowing on the ground.

For example, as shown in FIG. 7, one end of the anchor bolt 18 is screwed into an anchor nut 28 embedded in the intermediate block 2, and the other end of the anchor bolt 18 is formed in a vertical groove of the inner metal fitting 7. It is inserted and is fixed to the inner fitting 7 by the double nut 29. The anchor bolt 18 penetrates the water shield sheet 16.

Since the intermediate block 2 has irregularities and a joint material such as mortar is interposed between the adjacent intermediate blocks 2, the anchor bolt 18 is simply inserted into the inner metal fitting 7. If the round holes are only open, the anchor bolts 18 may not be attached or the attachment strength may be reduced because the anchor bolts 18 are driven into joints, for example.

On the other hand, as in the present embodiment, the inner metal fitting 7
When the vertical groove 20 is formed in the vertical groove 20, the anchor bolt 18 can be fixed to the inner metal fitting 7 at any part of the vertical groove 20, so that the anchor nut 28 can be embedded in a place where drilling work is easy and can be surely attached. There is an advantage that ease and installation strength can be secured.

Both the inner and outer metal fittings 7 and 8 may be made of a single metal plate and may be provided with elongated holes in a scattered manner. As shown in FIG. 7, the anchor bolt 18 is fitted with a protective pipe 30 made of a water-permeable and rust-proof material such as synthetic resin. Therefore, direct contact with soil can be prevented and durability can be improved. The protective pipe 30 may have a function of positioning the inner fitting 7 (that is, a function of setting the interval between the retaining walls 1).

Although not shown, a horizontal bracket extending toward the outer metal fitting 8 is fixed to the upper end of the inner metal fitting 7 and at the location of the protrusion 19 by welding or the like. The decorative decorative wood 11 is fixed to the both-sided bolts. A nut may be fixed to the horizontal bracket, and a bolt penetrating the decorative decorative wood 11 from above may be screwed into the nut.

.. Treatment of Terminal Section As shown in FIG. 8, at the terminal section of the earth retaining work 3, a spacer wood 31 is interposed between the inner and outer metal fittings 7, 8. The spacer wood 31 also has a makeup function.

As shown in FIGS. 8 and 9, the left and right ends of the earth retaining work 3 are end keystone plates 32.
The end panel 35 formed by fixing the wood group 33 to the connecting plate 34 is arranged outside the end keystone plate 32. A hook body 36 is fixed to the connecting plate 34 as an example of a hooking means by welding or a bolt head, and the hook body 36 is hooked to the anchor bolt 18. Therefore, the end panel 35 can be easily attached.

In this embodiment, the end panel 35 also has a makeup function. Needless to say, the structure and mounting method of the end panel 35 can be set arbitrarily. If the retaining wall has a bag-like shape, or if there are walls at the end of the retaining wall due to the provision of overhanging portions for reinforcement at appropriate intervals, the end keystone plate 6 or the end It is not necessary to provide the panel 35.

.. Summary As described above, by installing the frame device 4 according to the present invention, it is possible to easily build the earth retaining work 3 that functions as a flower bed at the location of the retaining wall 1. Not only can plants such as flowers be planted in the earth retaining work 3, but the frame device 4 is made of wood, so the appearance is very good.

If the wood constituting the main decorative wood group 9, etc., is corroded or damaged, the decorative wood for pressing 1
It can be easily replaced by removing 0. In this case, since the earth-stopping action is performed by the keystone plate 6, the soil will not fall when the wood is replaced. Therefore, maintenance is easy.

Since rainwater permeates the soil and flows out from the ground, there is no problem of drainage. Also, as shown in FIG.
Generally, in the retaining wall, drainage pipes 37 are buried at appropriate intervals, but the water flowing out from the drainage pipes 37 also flows out through the soil to the ground, so there is no problem.

Since the retaining wall 1 is generally inclined so as to form an obtuse angle with respect to the ground, if the planter is simply installed on the ground, the planter may be an obstacle. On the other hand, in the present invention, since the frame device 4 can be installed close to the wall surface of the retaining wall 1, the dead space that spreads closer to the wall surface than the vertical line rising from the lower end of the retaining wall 1 is used as the earth retaining work 3 for the flower bed. Can be used.

That is, the greening can be performed with almost no erosion of the walking space for people or the passing space for cars. Of course, if there is no space problem, it is possible to install the frame device 4 away from the retaining wall, and the installation location of the frame device 4 can be freely changed to change the front-back width dimension of the earth retaining work 3. One of the advantages of this embodiment is that it can be set arbitrarily.

It is also possible to crawl 42 and green the entire surface of the retaining wall 1.

The lattice frame 41 includes a main frame 43 having the same structure as the inner and outer metal fittings 7 and 8 used for the earth retaining work 3, and the horizontal frame 40 is fixed to the main frame 43 by screwing or welding. is doing. Needless to say, there is an appropriate space between the vertical and horizontal frames 39, 40 and the surface of the retaining wall 1.

Instead of providing the lattice frame 41, it is possible to use the main frame 43 to attach a large number of decorative wood groups for wall surfaces as in the frame device 4. This way
Since the entire surface of the retaining wall can be made up of wood and flowers can be planted and accented in the earth retaining structure 3 having a flower bed function, the appearance can be further enhanced.

In this embodiment, the soil of the growing section 5 is in contact with the retaining wall and the ground, but as shown by the chain double-dashed line in FIG.
It is also possible to manufacture an upwardly opening pot 44 having a keystone plate 6 on the front surface, and pour soil into the pot 44 (the pot 44 has a drainage hole). By doing so, since the pot 44 can be transported by a truck, the earth retaining work 3 can be easily installed and removed.

(8). Eighth Embodiment (FIGS. 28 to 34) By the way, a barrel 71 as shown in FIG. 28 is used for aging whiskey, and the barrel plate 7 constituting the body of the barrel 71 is used.
As shown in FIGS. 29 to 31, No. 2 has a shape in which both ends are narrow and curved in the longitudinal direction and the width direction.

The barrel 71 for aging the whiskey is generally 6
When the smell disappears in about 0 years, the aging mission ends and the barrel is abandoned. However, this barrel 71 is made of white oak of a considerable age and is 20m thick.
Since the thickness is about m to 35 mm and is thick, no slight deterioration in strength is observed even after the aging mission is completed. Also,
Since it uses white oak grain, it has a dense and heavy wood texture when hung on a plane or polished with santo paper.

In recent years, waste barrels that have been used for aging have been generated, and their reuse destinations are required. Flattening is also performed to facilitate reuse, but this increases the cost. Therefore, there is a demand for a recycling method that allows the barrel plate 72 to be used as it is. The present invention can also meet this demand, an example of which is shown in FIGS.

32A is a front view of the earth retaining work 3, FIG. 33B is a plan view, and FIG. 33 is XXXIII-XXXI of FIG.
II is a sectional view, and FIG. 34 is a sectional view taken along line XXXIV-XXXIV of FIG.

Also in this embodiment, the inner and outer metal fittings 7 and 8 provided with the convex portions 19 are used, and the inner and outer metal fittings 7 and 8 sandwich the end portion of the barrel plate 72 stacked in multiple stages. The barrel plate 72 as the main decorative material 10 remains curved without being corrected, and has a posture in which it is convex toward the soil in a plan view. This is to effectively support soil pressure. The pressing decorative material 10 is flattened.

In this example, the inner metal fitting 7 is in a posture in which the convex portion 19 faces the soil. Similar to the first embodiment,
The inner metal fitting 7 is fixed to the retaining wall 1 with anchor bolts 18. Of course, it can also be self-supporting.

In this embodiment, a soft water-impervious sheet 74 such as synthetic resin or rubber is used in order to prevent the soil from coming into contact with the barrel plate 72. Although not shown, the water-blocking sheet 74 contains seeds such as flowers at appropriate intervals.

Expanded metal 73 having a large number of holes (not shown) between the water-blocking sheet 73 and the soil.
Are arranged. The expanded metal 73 is held by the inner metal fitting 7 so as not to be tilted forward. Instead of the expanded metal 73, another perforated plate such as a lath plate or a wire mesh may be used.

As can be easily inferred from FIG. 32, for example, the large number of barrel plates 72 having unique curves are arranged vertically and horizontally, so that the earth retaining work 3 of this embodiment is a kind of outdoor art. It has a unique appearance and a unique beauty.

White oak grown by photosynthesis was felled into barrels, and the barrels spent a long time in a dark warehouse to grow the scent of whiskey. By being reborn as a component, it will once again be given a place to play an active part in shining sunlight, and will become a presence that enriches people.

The barrel plate 73 as the main decorative material that constitutes the majority of the soil retaining portion 3 does not need to be straightened.
Since it is sufficient to add some processing such as dimensional alignment and polishing, the shape of the barrel plate 72 can be used as it is and reused at low cost.

(9). Ninth Embodiment (FIGS. 35 to 36) The ninth embodiment shown in FIGS. 35 to 36 is also an example in which the barrel plate 35 is used as the main cosmetic material. 35 is a front view and FIG. 36 is a sectional view taken along the line XXXVI-XXXVI of FIG.

In this embodiment, the barrel plate 35 is cut and aligned so that its longitudinal end faces extend in parallel, and is arranged in an outwardly convex posture in plan view. Also, barrel plate 7
2 is fixed to a pillar (support member) 75 buried in the ground with a bolt 76 and a nut 77, respectively. The column 75 is covered with a cover member 77 from the inside, and the adjacent cover members 77 hold a metallic shield plate 78 so that it cannot lean forward.

(10). Tenth Embodiment (FIG. 37) Also in the tenth embodiment shown in FIG.
Are individually attached with bolts 76, but in this example, a burring portion 79 is formed on the column 75, and the bolts 76 are screwed into the burring portion 79. Therefore, the structure is simple.

Further, in this embodiment, a soft water shield sheet 74 is used as the shielding material. Therefore, the barrel plate 72
Is in contact with the soil via the water blocking sheet 74. The soil solidifies and loses fluidity after a certain amount of time,
No large pressure acts on the barrel plate 73. Therefore,
Even with such a structure, there is no problem in strength.

(11). Eleventh Embodiment (FIG. 38) In the embodiments below FIG. 32, the barrel plate 72 is arranged in a posture in which the wide surface thereof is vertical, but as shown as the eleventh embodiment in FIG. It is also possible to arrange the 72 so that its wide surfaces are located above and below.

When arranging the barrel plates 72 in such a posture, it is preferable to form a fence-like structure as a whole with a certain interval between the vertically adjacent barrel plates 72. As a means for arranging in such a manner, a bracket 80 may be provided on the inner metal fitting 7 as shown by the one-dot chain line, or a spacer 81 may be interposed as shown by the two-dot chain line.

(12). Twelfth Embodiment (FIG. 39) FIG. 39 also shows a barrel plate 72 used as a main decorative material. In this example, the barrel plate 72 is fitted with inner and outer metal fittings 82, 83.
The edge of the barrel plate 72 is sandwiched from above in the space formed between the two.

The inner and outer metal fittings 82, 83 are each formed in a T shape in a plan view, and the rearward extending portion 82a of the inner metal fitting 82 is formed in a bag shape so that the inner and outer metal fittings 82, 83 are formed.
The rearward extending portions 82a and 83a of the are connected by bolts.

Further, wires 84 for preventing falling are connected to the inner metal fitting 82. The wires 84 are fixed to the ground or a retaining wall. Also in this embodiment, the soft water-impervious sheet 74 is used as the shielding material. In addition, in the embodiment of FIG. 32 and subsequent figures, other plate materials may be used instead of the barrel plate.

(13). Others The present invention can be embodied in various ways other than the above embodiment. For example, the decorative material is not limited to wood such as thinned wood and barrel boards, but materials made of other materials such as ceramic boards can also be used.

The earth retaining work and the frame device according to the present invention are not limited to being used for greening retaining walls, parks, roads, plazas, school grounds, etc. it can. For example, it can be used for greening a concrete embankment or dam, or can be installed on the roof of a building or condominium or on a balcony to be used as a flower bed or a vegetable garden.

Alternatively, a row of frame devices consisting of two rows of frame devices is provided in a field to construct a kind of tall ridged earth retaining work, and this row of earth retaining works is constructed. It is also possible to cultivate crops such as fruits such as strawberries and fruits and vegetables such as tomatoes. When applied to a field in this way, a person can perform agricultural work without bending his or her back, and thus the burden on the farmer can be significantly reduced.

Furthermore, the frame device of the present invention is not limited to being used for earth retaining works, but can be used as a fence, for example.
