Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a greening structure of a structure, and for example, it is very efficient for greening cut and embankment slopes facing roads and residential land, and concrete wall surfaces such as concrete retaining walls. And it was developed to be reliable.

[0002]

BACKGROUND OF THE INVENTION Cut slopes, embankment slopes facing roads and residential areas, etc. due to the recent trend of environmental conservation and nature preference.
In addition, by actively greening concrete slopes such as concrete retaining walls, there is an attempt to create a landscape that gives people a feeling of comfort and healing, and such greening will be carried out in the future. It is becoming more and more important.

By the way, cut slopes and embankment slopes have hitherto been simply sprayed with mortar or concrete.
No greening was done.

Recently, however, the mortar / concrete slope has deteriorated and repair work has become necessary, which causes problems such as the demolition method, the dismantling method of the demolition shell, and the extension of the construction period. ing.

In this case, a method of spraying mortar or concrete again on the existing slope can be considered, but spraying mortar or concrete is an excellent method for protecting the slope, but on the landscape that does not harmonize with the surrounding landscape. Had been pointed out earlier.

For this reason, recently, slope greening has been actively carried out, and as an example, a method of installing a vegetation base material or a vegetation bag on the slope is generally performed. .

[0007]

However, this type of slope greening method can protect and green the slope in the case of a relatively gentle slope, but in the case of a steep slope. However, there is a problem that not only the base material is easily washed away but also the growth of plants is poor, and it is not possible to expect stable slope construction in terms of strength.

As a method for greening a substantially vertical wall surface such as a concrete retaining wall, for example, plants such as ivy are planted on the upper or lower part of the wall surface, and the nets or fences are used to climb up and down to make the trees green. There are known methods such as a backing basket and a method of directly fixing a plant planter to a wall surface like a backing basket.

[0009] However, these are only "visual greening" in which the slope is covered with plants superficially, and the destruction of the ecosystem due to the loss of the natural environment has become a social problem in recent years. This is far from the desired greening as a habitat for wildlife.

Even when a ground cover plant or a garden plant is planted in a planting pot, high-temperature drying conditions are often severe, and in order to grow the plant, watering, weeding, regular planting, etc. Because maintenance is required,
There were issues such as a considerable cost burden.

The present invention has been made in order to solve the above problems, and in particular, provides a greening structure of a structure which can very suitably green the slope and the concrete wall surface and is extremely stable. The purpose is to

[0012]

In the greening structure for a structure according to claim 1, a plurality of wall surface blocks are stacked with the slope on the back and stepped back to the rear surface side, and the wall surface block is formed by the method. The surface is fixed by a rod-shaped fixing member, a filling material is filled between the wall surface block and the slope, and plants are planted at the upper end of each step.

The present invention is particularly directed to greening of natural ground slopes, cut slopes, embankment slopes, and concrete slopes facing roads, residential land, rivers and the like. In this case, by changing the receding length of each wall block, it is possible to freely adjust the slope of the slope after greening, and it is possible to form a green slope that matches the surrounding landscape.

As the filling material to be filled between the wall block and the slope, a locally generated material that can be easily obtained locally can be used, and only the upper end of each wall block has a vegetation base. It is possible to green the whole area by filling it with soil as a material.

In the greening structure for a structure according to a second aspect of the present invention, a plurality of wall surface blocks are stacked with the wall surface as a back, and the wall surface blocks are receded in a stepwise manner on the back surface side thereof, and the wall surface blocks are fixed to the wall surface by a rod-shaped fixing member. The filling material is filled between the wall surface block and the wall surface, and plants are planted at the upper end of each step.

The present invention is particularly applicable to concrete wall surfaces of civil engineering structures such as concrete retaining walls or piers constructed facing roads and residential land, concrete wall surfaces of architectural structures such as concrete buildings, and block walls. The purpose is to reforest. Also in this case, by changing the receding length of each wall surface block, the wall surface gradient after greening can be freely adjusted, and a greened wall surface that matches the type of structure can be formed.

In principle, the filling material in this case may be a locally generated material as in the first aspect of the invention, but the weight of the filling material acts on the building especially when greening the walls of the building. In such a case, use a lightweight material such as foam mortar, and fill the entire concrete wall surface by filling the soil such as vegetation base material only on the upper end of each wall block. It can be carried out.
Further, as the wall block, it is desirable to use a block made of lightweight concrete, foam mortar or resin mortar in order to reduce the weight as much as possible.

The greening structure of a structure according to a fourth aspect is the greening structure of a structure according to the first, second or third aspect, in which adjacent wall blocks are laminated in a state of being interlocked with each other. It is characterized by that.

As a mode of combining the wall blocks by interlocking in this case, for example, a method of engaging the wall blocks with each other by engaging the projections and the recesses or cavities formed on the contact surface between the upper and lower wall blocks with each other Alternatively, there is a method of engaging the pin formed in the contact surface portion between the upper and lower wall surface blocks with the pin hole to combine the wall surface blocks.

Furthermore, when the wall blocks are laminated, for example, the joints between the wall blocks of the adjacent stages in the lateral direction are not continuous in the vertical direction but are alternately shifted to the left and right, that is, so-called "blurred joints". Interlocking by stacking stepped wall blocks and engaging the protrusions protruding from the upper end of each stepped wall block with the cavities formed between the wall blocks stacked above Then, by combining the upper and lower wall blocks, it is possible to form a green slope or a green wall in which the wall blocks of each step do not laterally shift in the front-rear direction or the left-right direction.

Further, in this case, it is not necessary to combine all the wall blocks by interlocking, and only the wall blocks laminated on the part where a large earth pressure acts are combined by interlocking, and the earth pressure is not particularly large. The wall block laminated on the part may be simply laminated. Rather, such stacking can not only avoid structural waste, but can also improve the efficiency of construction and reduce construction costs.

[0033]

1 and 2 show an example of a greening structure constructed to green a natural slope facing a road or a residential area. A plurality of wall surface blocks 2 are stacked in front of each other. A locally generated material is filled as the filling material 3 between the ground slope 1 and the wall surface block 2.

The wall block 2 is, for example, as shown in FIG.
As shown in (e), it has a front surface flange 2a, a rear surface flange 2b, and a web 2c, and is extremely stable and self-supporting as it is from reinforced concrete, reinforced concrete, or fiber reinforced concrete mixed with reinforcing fibers such as carbon fiber. It is integrally formed in a substantially H-shaped (or I-shaped) plane.

Also, the front surface flange 2a and the rear surface flange 2
The fixing groove 2d is formed in each of the upper ends of the web 2b and the web 2c. The fixing groove 2d is continuous in the axial direction at the upper end of the surface flange 2a and the web 2c, and the upper end of the rear flange 2b. In this case, the fixing groove 2d of each portion is formed continuously in the direction perpendicular to the axis (width direction), and is formed continuously as one groove. A protrusion 2e is formed on the upper end of the web 2c, and a recess 2f into which the protrusion 2e can be fitted is formed on the lower end of the web 2c.

In this case, the wall surface block 2 has a height h of 20 to 150 cm, a width w of 30 to 100 cm, and a depth d in consideration of ease of handling such as transportation and workability.
Is about 20 to 60 cm, and the weight is 20 to 1
It is formed to have a weight of about 50 kg.

The wall surface block 2 thus formed is
In front of the ground slope 1, they are adjacent to each other in the lateral direction and are laminated in a plurality of stages. The wall blocks 2 are stacked in a stepwise manner by retreating every few steps toward the natural slope 1 side. Further, some of the wall blocks 2 of each stage are fixed to the ground slope 1 by a reinforcing bar 4 installed as a rod-shaped fixing member as shown in FIGS. 1 (b) and 1 (c), respectively. There is.

Further, a cavity portion 5 composed of both front surface flanges 2a, back surface flanges 2b and webs 2c is formed between the laterally adjacent wall surface blocks 2 and 2 of each step, and each cavity portion 5 has an inner portion. Filling material 3 is filled, and in particular, the uppermost cavities 5 of each stage are filled with vegetation base material such as soil as filling material 3, and plants 6 such as herbaceous plants and woody plants are filled in this portion. It has been planted.

Further, the wall surface blocks 2 of the respective stages are, for example, as shown in FIG. 2, surface flanges 2 which are laterally adjacent to each other.
The joints a between a and 2a are laminated so that they are not continuous in the vertical direction and are shifted left and right alternately, that is, so-called "blurred joints". 5 between adjacent wall blocks 2 and 2
The wall blocks 2 that are vertically and laterally adjacent to each other are interlocked with each other by interlocking the projections 2e of the wall blocks 2 with the hollow portions 5 by fitting with each other.

The reinforcing bar 4 as a rod-shaped fixing member is horizontally bridged between the ground slope 1 and the wall block 2, and the tip side (wall block 2 side) 4a thereof is fixed to the wall block 2 and the rear end. The side (ground slope 1 side) 4b is fixed to the ground slope 1.

In this case, the tip side 4a of the reinforcing bar 4 is formed in a substantially T-shape or L-shape in a plane as shown in FIGS. 1B and 1C, and the tip 4a is a wall surface. It is fixed by being continuously inserted into the surface flange 2a of the block 2 and the fixing groove 2d of the web 2c.

Since the tip side 4a of the reinforcing bar 4 is fixed in the surface flange 2a of the wall surface block 2 and the fixing groove 2d of the web 2c in this way, the tip side 4a is the weight of the upper wall surface block 2. The tip end side 4a of the reinforcing bar 4 can be securely and firmly fixed to the wall surface block 2 because it is constrained by and is not pulled out by friction with the peripheral surface in the fixing groove 2d.

Further, since the front end side 4a of the reinforcing bar 4 is fixed across the fixing grooves 2d of the wall block 2 of two or three or more adjacent in the lateral direction,
Since it is possible to simultaneously fix a plurality of laterally adjacent wall blocks 2 with a single reinforcing bar 4, it is extremely economical and the workability is significantly improved.

Further, since the front end side 4a of the reinforcing bar 4 is stable in the fixing groove 2d, even if the wall surface block 2 located thereabove is displaced forward due to stress concentration due to earth pressure, it is underneath. The tip side 4a in the fixing groove 2d of the side wall block 2 remains connected and is not destroyed. Rather, the wall block 2 moves forward to alleviate stress concentration due to earth pressure and stabilize soil. Can keep retaining walls.

On the other hand, the rear end side 4b of the reinforcing bar 4 extends substantially horizontally in the filling material 3 toward the ground slope 1 side, and the anchor hole 7 formed horizontally on the ground slope 1 is formed. It is fixed inside. In this case, the rear end side 4b of the reinforcing bar 4 is inserted into the anchor hole 7 and is fixed by filling a solidifying material 8 such as high-strength concrete around the anchor hole 7.

The rear end side 4b of the reinforcing bar 4 is fixed to the ground slope 1 in a downward slanting direction to form the rear end side 4b.
The fixing power of b can be remarkably enhanced. Also, FIG.
As shown in (a), the anchor member 9 is attached to the natural slope 1.
May be fixed, and the rear end side 4b of the reinforcing bar 4 may be connected thereto via the turnbuckle 10.

By doing so, not only can the length of the reinforcing bar 4 be freely set, but by tightening the turnbuckle 10 after installing the reinforcing bar 4, not only can the slack of the reinforcing bar 4 be eliminated, Each wall block can be firmly fixed.

Further, as shown in FIGS. 4 (b) and 4 (c), for example, a beam member 11 or a column member 12 made of shaped steel such as H-section steel or reinforced concrete is installed on the ground slope 1, The rear end side 4b of the reinforcing bar 4 may be fixed to the beam member 11 or the column member 12. In this case, the beam member 11
The column member 12 may be fixed to the ground slope 1 by a plurality of anchor members 13, and the rear end side 4b of the reinforcing bar 4 may be fixed to the beam member 11 or the column member 12 by the fixing nut 14.

By doing so, the beam member 11 or the column member 12
Need only be firmly fixed to the ground slope 1 with a few anchor members 13, and each rear end side 4b of each reinforcing bar 4 needs to be anchored by drilling an anchor hole in the ground slope 1. Because there is no
It is possible to significantly reduce the construction work.

In this case, the reinforcing bar 4 is made of round steel, deformed bar steel, screw reinforcing bar or the like, and the diameter of the reinforcing bar 4 and the length of the rear end side 4b are appropriately determined.

Further, since the rear end side 4b of the reinforcing bar 4 is fixed to the ground slope 1 directly or through the beam material 9 or the like, the friction effect between the reinforcing bar 4 and the base material 3 is improved. Each wall block 2 can be securely and firmly fixed without expectation.

As a result, the reinforcing bar 4 and the wall block 2
Unlike the conventional reinforced earthwork method that expects a friction effect between and, it is not necessary to consider the length of the reinforcing bar 4 in particular, so the length of each reinforcing bar 4 should be as short as possible. By reducing the number of bars 4 as much as possible, it is possible to achieve labor saving and economic efficiency in construction.

It should be noted that the reinforcing bar 4 does not have to be laid for each stage as long as a sufficient pulling-out resistance force against earth pressure from the filling 3 acting on the wall block 2 of each stage can be obtained, and a plurality of bars are not required. It may be laid every other steps.

Rather, it is preferable that the number of the reinforcing bar 4 is small, it is economical, and it does not hinder the filling and rolling of the filling material 3, and the rolling is easy in construction.

As the filling material 3, for example, a large amount of excavated soil that is locally produced is used, and in particular, the portion to be planted is filled with the soil.

FIG. 3 shows an example of a greening structure constructed for greening the wall surface of an existing concrete retaining wall. In the figure, the rear end side 4b of the reinforcing bar 4 is horizontal to the wall surface of the concrete retaining wall 15. It is fixed in the anchor hole 7 formed in. Other configurations are almost the same as the case of greening the slope of the natural slope 1.

When greening the concrete retaining wall 15, a through hole (not shown) is provided in the concrete retaining wall 15 to connect the front filling material 3 of the concrete retaining wall 15 to the ground a on the back side. By doing so, natural watering of the plants 6 from the ground side becomes possible, and maintenance becomes easy.

FIGS. 5 (a) and 5 (b) show another example of the greening structure of the structure according to the present invention, in which the vertical joint a between the wall blocks 2 and 2 adjacent in the horizontal direction of each stage is The wall surface blocks 2 are stacked so as to form a so-called "potato joint" that is continuous in the vertical direction.

The upper and lower wall blocks 2 of each step are fitted with the projections 2e and the recesses 2f (see FIGS. 1 (d) and 1 (e)) formed on the upper and lower ends of the web 2c, respectively. Are interlocked with each other.

Further, in the example of FIG. 5 (b), instead of providing the fixing grooves in the upper end portions of the front surface flange 2a, the rear surface flange 2b and the web 2c of each wall surface block 2, fixing is performed in the upper end portion of the rear surface flange 2b. Insert 1
6 is buried.

A fixing plate 17 is provided on the tip side 4a of the reinforcing bar 4 in a protruding manner. Then, the tip side 4a of the reinforcing bar 4 is fixed by fixing the fixing plate 17 with a fixing bolt 18 screwed into the insert 16. Other configurations are almost the same as the example of FIG.

FIGS. 6 (a) to 6 (c) also show an example of a greening structure of the structure according to the present invention, in which the wall block 2 is stepwise receded on the ground slope 1 side for each step and laminated. Is
Further, particularly in the examples of FIGS. 6B and 6C, a steel material such as a strip steel or a lattice member 19 such as a reinforcing bar grit or a wire mesh is used instead of the reinforcing bar. The other configuration is the same as the previous example.

The greening structure in this case is particularly suitable for greening a slope with a relatively gentle slope such as a slope of a bank along a river.

FIGS. 7 (a) to 7 (c) also show an example of a greening structure of the structure according to the present invention, and as a wall block, for example, a surface as shown in FIGS. 7 (b) and 7 (c). At the upper end of the flange 2a and at the upper end of the rear flange 2b, a planting cavity 2g as a planting section and a fixing groove 2e, respectively.
A wall block 2 having a is used.

The blocks 2 for wall surfaces are stacked so as to recede in a stepwise manner on the ground slope 1 side. In addition, the planting cavity 2g of each wall block 2 is filled with the vegetation base material, and the plants 6 are planted.

Further, in the example of FIG. 7 (c), the grid member 19 is used instead of the reinforcing bar, and the grid member 1 is attached to the upper end of the rear surface flange 2b of the wall surface block 2 accordingly.
A fixing groove 2d into which the nine horizontal members 19a and the vertical members 19b can be inserted is formed.

This greening structure is also suitable for greening on a slope with a relatively gentle slope such as a slope of a bank along a river.

FIGS. 8A to 8D show another example of the wall block used here, and particularly FIGS. 8A and 8B.
The wall block shown in FIG. 1 has a front surface flange 2a, a rear surface flange 2b, and webs 2c and 2c, respectively, as shown in the drawing, and the front surface flange 2a and the rear surface flange 2 are provided at the center.
It has a cavity 2g for planting composed of b and the webs 2c, 2c, and further has a fixing groove 2d at the upper end of the front surface flange 2a, the rear surface flange 2b and the web 2c.

9 (a) and 9 (b) show another example of the greening structure of the structure according to the present invention. As shown in the figure, the wall block 2 is the ground slope 1 or the concrete retaining wall 15. Previously, they are adjacent to each other in the lateral direction and are stacked in multiple stages.

The wall surface blocks 2 are stacked stepwise by retreating every few steps. Further, some of the wall blocks 2 at each stage are fixed to the ground slope 1 or the concrete retaining wall 15 by the reinforcing bar 4 installed as a rod-shaped fixing member.

A planting section 20 is formed on the uppermost stage of each stage, and the plants 6 are planted in the planting section 20. In this case, the planting section 20 of each step is formed by retracting the wall surface block 2 to fill the gap formed between the upper and lower steps with the vegetation base material.

FIGS. 10A to 10C and FIG.
(A), (b) shows an example of a greening structure of a concrete wall surface that forms a vertical surface, such as a concrete wall surface of a building, and in the example of FIGS. 10 (a) to (c), For example, a wall block 2 as shown in (b) and (c) is used, each wall block 2 is stacked in a plurality of steps in front of a vertical concrete wall surface 15A, and the wall blocks 2 are projected every other step. The wall surface A is formed in an uneven shape.

Then, the planting cavities 2g of each of the projected wall surface blocks 2 are filled with a vegetation base material, and plants 6 are planted thereon. In addition, by filling a light weight filling material such as foam mortar as the filling material 3 between each wall surface block 2 and the concrete wall surface 15A, the weight of the building is not burdened.

In the figure, the wall blocks 2 on the same step are projected laterally so as to be continuous in layers.
The design can be improved by randomly (randomly) protruding arbitrary blocks.

In the example of FIGS. 11A and 11B, the connecting rod 21 is inserted between the upper and lower wall blocks 2 and 2 stacked in the example of FIG. 10, and the reinforcing rod is attached to the connecting rod 21. The tip side 4a of the bar 4 is connected. in this case,
The connecting rod 21 is continuously inserted into the vertical hole 2n formed in each wall surface block 2.

By doing so, the upper and lower wall blocks 2 can be firmly connected to each other, and the plurality of wall blocks 2 can be very easily fixed to the concrete wall 15A by the reinforcing bar 4 via the connecting rods 21. You can

12A to 12G show another example of the wall block used in the greening structure of the structure according to the present invention.

Each wall block has a surface flange 2
a, a rear surface flange 2b and a web 2c, respectively. Particularly, in the structure shown in FIGS. 12 (a) and 12 (b), a connecting key 2h made of a reinforcing bar, a stud bolt or the like is provided on the upper end of the flange 2a. The connecting key 2 is provided at a predetermined interval in the axial direction (lateral direction of the wall body A) and is provided at the lower end of the surface flange 2a corresponding to the connecting key 2h.
A key hole 2i into which h can be inserted is formed.

Then, when the plurality of wall surface blocks 2 are stacked in a plurality of stages, the connecting key 2h and the key hole 2i of the vertically adjacent wall surface blocks 2 and 2 are engaged (the connecting key 2h is inserted into the key hole 2i). The upper and lower wall surface blocks 2 can be stacked in a state of being combined with each other by interlocking.

Further, in the structure shown in FIG. 12C, the connecting groove 2j is formed especially at the upper end of the surface flange 2a.
Are continuously formed in the axial direction of the surface flange 2a. Then, when the plurality of wall surface blocks 2 are laminated in a plurality of layers, the connecting grooves 2j, 2j of the wall surface blocks 2, 2 adjacent in the horizontal direction of each stage are continuous in the horizontal direction and are adjacent in the horizontal direction. By inserting the connecting rod 22 across the connecting concave grooves 2j of the plurality of wall surface blocks 2, the plurality of wall surface blocks 2 that are laterally adjacent to each other are joined to each other.

Further, in the drawing shown in FIG. 12 (d), a protrusion 2k and a recess 21 which are continuous in the longitudinal direction of the surface flange 2a are formed at the upper end and the lower end of the surface flange 2a, respectively. . Then, when the plurality of wall surface blocks 2 are stacked, the wall surface blocks 2, 2 that are vertically adjacent to each other are stacked.
By engaging the projecting portion 2k and the concave portion 2l, the upper and lower wall surface blocks 2 can be stacked in a state of being combined with each other.

Further, in the drawing shown in FIG. 12 (e), in particular, the opening 2m penetrating downwardly is formed in the web 2c, so that the weight of the retaining wall block 2 is reduced and the material is saved. By filling the filling material (gravel) in the opening 2m, the shear resistance between the upper and lower wall blocks 2, 2 is increased to prevent deformation of the wall A due to earth pressure and drainage is improved. ing. Further, the wall surface block 2 shown in FIG. 12 (f) is formed of a surface flange 2a and a plurality of webs 2c, 2c protruding in parallel on the back side thereof, and a space between the webs 2c, 2c is filled with a base material. It has a cavity 2g for planting.

Further, the wall surface block 2 shown in FIG. 12 (g) is formed in a plane T shape from the surface flange 2a and the web 2c projecting from the rear surface side thereof.

[0084]

The present invention is as described above,
In particular, a plurality of wall blocks are stacked in a stepwise manner with the slope or wall as a back, the wall block is fixed to the ground by a rod-shaped fixing member, and a filling material is provided between the wall block and the slope or wall. Since it is filled with and the plants are planted on the upper end of each step, it is possible to very easily green the ground slope and the concrete wall surface.

Further, since the laminated wall blocks are directly fixed to the ground or the wall surface by the rod-shaped fixing member, the wall blocks can be firmly fixed, have excellent earthquake resistance, and are structurally very stable. A green structure can be constructed.

On the wall block side of the rod-shaped fixing member,
Since it is inserted horizontally in the fixing groove formed at the upper end of the wall block and is fixed, a large frictional resistance is obtained at the contact surface between the upper and lower wall blocks, so that the wall block receives large earth pressure. But it doesn't collapse easily,
An extremely stable green structure can be constructed.

Also, by fixing the rod-shaped fixing member across the fixing grooves of two or three or more wall members that are laterally adjacent to each other on the wall surface block side, one rod-shaped fixing member can be used. Since it is possible to connect and fix multiple wall blocks adjacent to each other in the lateral direction, both workability and economy are excellent.
