Description

  The present invention relates to a planting structure, typically a planting structure used for storing turfgrass, and a laying body. Further, the laying body is used to greenen a building site, a rooftop, a park, a parking lot, and the like. On how to do.

  In recent years, greening of building sites, rooftops, parks, parking lots, and the like has been promoted as a countermeasure for heat island phenomenon in urban areas and as a measure to form a green living environment.

  As a greening technique of this type, a construction method is widely known in which lawn material formed in a mat shape having a width dimension of about 300 mm and a longitudinal dimension of about 350 mm is laid on the ground surface. For example, the invention described in Patent Document 1 relates to a skewer that is used to drive a lawn that is continuously arranged vertically and horizontally and fix it directly to the ground surface. In addition, when a laying area such as a park or a playground becomes wide, curled turf wound like a material is used as a lawn material.

  In addition to the significance of heat island phenomenon measures and living environment measures, the parking lot greening technology has another significance of clearing legal regulations. For example, companies that have vast industrial sites are subject to regulations that the green space area should be secured at a certain ratio to the site area under the Factory Location Law.

  According to the green space regulations under the Factory Location Law, a transportation company that owns a large number of transport trucks and has a parking space for transport trucks on the premises, even if there is a need for facility expansion, If we cannot secure the plan, we must give up the plan. Therefore, in recent years, the market demand for the greening technology of parking lots is increasing as a means for securing the above-mentioned green space area.

  Specific problems to be solved in realizing greening of parking lots are the problem that lawn materials are pressed and compacted by the loading load of automobiles, and the problem that lawn materials are peeled off from the ground due to friction received from rotating tires. There is.

  With respect to the above-described problem, Patent Document 1 cannot protect the lawn from the load on the automobile and the friction of the rotating tire. Further, in Patent Document 1, when a parking lot having a large site area is to be greened, the number of on-site work processes such as winding grass placement work and skewering work on the winding grass increases, and the construction period becomes longer. Incurs high costs.

  On the other hand, for example, Patent Documents 2 and 3 are known as conventional techniques for solving problems peculiar to greening of parking lots. Patent Document 2 discloses a lattice-shaped resin-made plant growth protection board provided with tread pressure resistance protrusions. This plant growth protection board is arranged on lawn, and the tread pressure resistance protrusions are used to reduce the pressure of pedestrians. It protects the lawn from the load on the car.

  Patent Document 3 discloses a lawn protection pallet in which a large number of cylinders are connected in a net shape, and a lawn storage pallet is provided in each cylinder to store the soil and turf grass. Grow turfgrass or place a small piece of grass in each tube.

  However, even in the inventions described in Patent Documents 2 and 3 described above, similarly to Patent Document 1, it cannot be said that the problems peculiar to the greening of the parking lot are sufficiently solved. With the structure of the plant growth protection panel shown in Patent Document 2, it is not possible to ensure sufficient mechanical strength to withstand the load on a large vehicle such as a truck. In addition, prior to the process of placing the plant growth protection board, a process of laying lawn materials and curly lawn on the ground surface is required, which increases the number of on-site work processes, prolongs the construction period, and increases construction costs. .

  Moreover, in the lawn protection pallet described in Patent Document 3, the turf grass growing process and the lawn material cutting work are troublesome. In particular, if a parking lot with a large site area is planted, the construction period will be prolonged and the construction cost will increase.

  By the way, as the greening technology spreads, this kind of planting structure and a laying body in which turf grass is stored in the planting structure must be solved in accordance with actual use. New problems have arisen. That is, when a pedestrian walks on the laying body wearing women's shoes with long and narrow buttocks such as pumps and high heels, the toe side of the shoe is supported by the tread surface of the laying body, while only the buttocks bring turf grass outside. It will be immersed in the opening part for exposing. As a result, the immersion distance at the tip of the buttock is increased by the thickness of the laying body than when walking directly on the lawn, and the balance is greatly lost, causing an unexpected fall accident.

  In addition, the heel portion once immersed in the opening portion comes into contact with the inner surface of the opening portion unless it is pulled up in a direction perpendicular to the tread surface. That is, if the buttocks immerse into the opening during walking, the entire shoe is fixed at the immersive place, causing an unexpected fall accident.

  In addition, the turf that fits in the opening pierces the turf grass, which causes a problem that the turf grass is damaged.

  The greening technology that fully realizes the above-described heel measures for women's shoes has not yet been found. At present, signboards that are not allowed to enter are installed on lawn areas such as parks, and signboards are only installed on lawn areas such as parking lots to alert pedestrians to fall.

The plant material is in the form of a sheet or mat, and is stored in the internal space of the main body member in a direction in which the leaf tips can be exposed from the opening of the main body member. Covered by.

  In greening using the laying body concerning the 1st mode of the present invention, a plurality of laying bodies are arranged in a construction object field, and adjacent laying bodies are combined.

  According to the 1st aspect of this invention, the main-body member which comprises the structure for planting is bottomed box shape, Comprising: An opening part faces the bottom part and is connected to internal space. According to this structure, the plant material can be guided to the internal space through the opening, and the plant material can be placed on the bottom. Therefore, the laying body can be carried together with the plant material stored in the main body member, improving the construction efficiency such as the transportation work from the assembly site to the construction site and the laying work in the construction target area at the construction site. To do. In addition, since the laying bodies can be rearranged even after the construction, the number of on-site work processes can be reduced, the construction period can be improved, and the construction cost can be reduced.

  The plant material is in the form of a sheet or a mat, and is stored in the internal space in such a direction that the leaf tips can be exposed from the opening. According to this structure, a green landscape is produced by exposing the leaf tip of the plant material to the outside through the opening.

  In the structure of a laying body that produces a green landscape by exposing the leaf tips of the plant material stored in the internal space of the main body member to the outside through the opening of the main body member, a person walking on the laying body or parking As a safety measure for the vehicle user, it is necessary to secure the safety of the pedestrian by preventing the heel and toe of the shoe from getting caught in the opening. In particular, with this type of laying body, it is considered to be most dangerous when walking with women's shoes having elongated buttocks such as pumps and high heels.

  In order to meet the above-described demand, the planting structure according to the first aspect of the present invention includes a protective member, and the protective member covers the opening of the main body member. According to this structure, even when a pedestrian walks on the laying body, the heel and toe of the shoe are not easily caught by the opening.

  Further, the protective member has a plurality of through holes in the plane. The through-hole has a hole shape through which the tip of the buttocks of women's shoes cannot pass, so even if a pedestrian walks on the laying body wearing women's shoes with elongated buttocks such as pumps and high heels. In addition, it is possible to avoid the problem that the buttocks are immersed in the planting structure. Therefore, while protecting a plant material from the buttocks of women's shoes, the fall accident which arises when a buttocks immerses inside the structure for planting can be prevented, and the safety of a pedestrian can be ensured.

  In the state in which the plant material is stored in the internal space of the main body member, the surface of the plant material is covered with a protective member. Since the protective member has a plurality of through holes in the surface, a green landscape is produced by exposing the leaf tips of the plant material to the outside through the through holes.

  The column part of the main body member has a tapered shape having a flat front end surface at the front end part, is formed integrally with the bottom part, and a plurality of protrusions are provided in a matrix form at the bottom part. The protection member is supported by the tip portion of the column portion in a state of covering the opening. That is, the pillar part of the main body member supports the protective member from the bottom side by the tip portion that penetrates the plant material housed in the internal space and is exposed on the surface of the plant material. According to this structure, a height difference arises between the front end surface of a pillar part, and the surface of a plant material, and the space according to this height difference is ensured. Therefore, it is possible to support the external force such as the pedestrian's stepping pressure, the load on the automobile, and the friction received from the rotating tire by the front end surface of the pillar portion, and protect the surface of the plant material from the external force.

Since the column portion is formed integrally with the bottom portion of the main body member, it has excellent mechanical strength against external force. Furthermore, since the plurality of column portions are provided in a matrix shape at the bottom, the external force can be dispersed and supported by the front end surfaces of the column portions. Therefore, since the plurality of pillars that can reliably protect the plant material from external forces are projected in a matrix at the bottom, the roots of the plant material freely grow the internal space of the main body member, and rainwater Etc. freely move in the internal space of the main body member avoiding the pillar portion. Therefore, it is possible to reduce plant material growth costs and maintenance management costs after laying the laying body.

2. Second aspect of the present invention The planting structure according to the second aspect of the present invention includes a main body member and a protective member. The main body member has a first main body member and a second main body member.

  The first main body member has a plurality of openings, a first substrate part, a plurality of pillars, and an internal space. Each of the plurality of openings penetrates from one surface of the first substrate portion to the other surface, and is arranged in a matrix on the first substrate portion. Each of the plurality of column portions has a tapered shape having a flat tip surface at the tip portion, is formed integrally with the first substrate portion, and is projected in a matrix shape on the other surface of the first substrate portion. Yes.

  The second main body member has a second substrate portion, a plurality of drainage portions, and a plurality of recesses. The plurality of drainage portions fall from one surface of the second substrate portion to the other surface, and are arranged in a matrix on one surface of the second substrate portion. Each of the plurality of recesses is a bottomed hole, has a shape that matches the peripheral surface of the tip portion of the column portion and the tip surface, and is arranged in a matrix on one surface of the second substrate portion.

  The first main body member and the second main body member are arranged such that the other surface of the first substrate portion and one surface of the second substrate portion face each other, and the tip portion of the column portion in the arranged state. Is fitted in the recess of the second body member. The internal space is formed between the facing surfaces of the other surface of the first substrate portion and the one surface of the second substrate portion.

  The protective member has a plurality of through holes in the surface and covers the opening. The through-hole has a hole shape through which the tip of the heel of the women's shoe cannot pass.

  The planting structure described above is combined with a plant material to constitute a laying body. The plant material is in the form of a sheet or mat, and is stored in the internal space of the main body member in a direction in which the leaf tips can be exposed from the opening of the main body member (first main body member). The surface of the plant material is covered with a protective member.

  In greening using the laying body concerning the 2nd mode of the present invention, a plurality of laying bodies are arranged in a construction object field, and adjacent laying bodies are combined.

  The second aspect of the present invention has a characteristic configuration in common with the first aspect of the present invention in that the opening for exposing the leaf tips of the plant material is covered with a protective member. Due to the characteristic configuration, the same effects as those of the first aspect of the present invention can be achieved. For example, the plant material is stored in the internal space in a direction in which the leaf tips can be exposed from the opening of the main body member, and the surface of the plant material is covered with the protective member in the stored state. According to this structure, the leaf tip of the plant material is exposed to the outside through the opening of the main body member and the through hole of the protective member, and a green landscape can be produced.

  Since the protective member covers the opening of the main body member, even when a pedestrian walks on the laying body, the heel and toe of the shoe are less likely to get caught in the opening. Moreover, since the through hole of the protective member has a hole shape through which the tip of the buttocks of the women's shoes cannot pass, when a pedestrian walks on the laying body wearing women's shoes having an elongated buttocks However, the problem that the buttocks immerse inside the planting structure is avoided. Therefore, while protecting a plant material from the buttocks of women's shoes, the fall accident which arises when a buttocks immerses inside the structure for planting can be prevented, and the safety of a pedestrian can be ensured.

  Furthermore, in the planting structure according to the second aspect of the present invention, the first and second main body members constituting the main body member include the other surface of the first substrate portion and one surface of the second substrate portion. Are arranged facing each other, and the tip end portion of the column portion of the first main body member is fitted into the recess of the second member. According to this structure, an internal space having an interval corresponding to the height dimension of the column portion is formed between the opposing surfaces of the first and second main body members. Therefore, by storing the plant material in this internal space, the plant material can be sandwiched between the first and second main body members.

  Since the interval between the first and second body members is regulated according to the height dimension of the pillar portion, the plant material having various thickness dimensions can be obtained by adjusting the height dimension of the pillar portion in advance. It becomes possible to hold between the first and second body members.

  The pillar portion of the first body member has a tapered shape having a flat tip surface at the tip portion, and is formed integrally with the first substrate portion, and a plurality of matrix portions are formed on the other surface of the first substrate portion. Even if an external force such as a pedestrian's treading pressure, an automotive load, or friction received from a rotating tire is applied to one surface of the first board portion, the external force is pillared. It can be supported by the part. In other words, even if an external force is applied to one surface of the first substrate portion, the distance between the first and second body members is kept constant, and the plant material is pressed and solidified by the external force. There will be no problem.

  Since the whole circumference of the part exposed to the outside from the opening is surrounded by one surface of the first substrate part, the external force is received by one surface of the first substrate part, and the surface of the plant material is Protected from external forces.

  A plurality of openings of the first body member are arranged in a matrix on one surface and the other surface of the first substrate portion. Usually, if the opening area of an opening part is made small, a plant material can be protected from external force. However, if the opening area of the opening is reduced, the exposed area of the plant material is reduced by that amount, and a green landscape cannot be produced. Therefore, in the present invention, by arranging a plurality of openings in a matrix, the opening area of each opening is reduced, and the overall opening area is secured to the maximum. Therefore, the conflicting demands of protecting plant materials from external forces and realizing a green landscape can be achieved simultaneously.

  Since the first board part and the plant material are integrated by the pillar part in the main body member, even if the friction of the rotating tire is applied to the first board part, the main body member includes the plant material. The braking force added with the weight of works. For this reason, improper movement such as the body member leaving the plant material and moving laterally is suppressed, and it becomes possible to continue protecting the plant material.

  As described above, according to the present invention, there is provided a planting structure, a laying body, and a method for greening using a laying body that can protect the plant material stored from external force and at the same time ensure the safety of pedestrians. It can be provided, and the construction efficiency of the laying body can be further improved.

  The protective member 30 shown in FIGS. 4 to 8 is disposed inside the first opening 12, and in the disposed state, one surface 31 of the protective member 30 is lower than the distal end surface 141 of the column portion 14, and the first It is in a position lower than the opening edge of the opening 12. A height difference is generated between the one surface 31 of the protection member 30 and the tip surface 141 of the column portion 14, and a space g1 corresponding to the height difference is formed.

  The space g <b> 2 between the opposing surfaces of the first base body 11 and the protection member 30 is regulated to be constant by the coupling relationship between the main body member 10 and the protection member 30, specifically, the height of the diameter reduction portion 142. It is regulated to be constant according to the position T142. And the spatial expansion formed between the opposing surfaces of the main body member 10 and the protection member 30 by the space g2 is used as the internal space 101 for storing the plant material. Therefore, the diameter dimension decreasing part 142 determines the volume of the internal space 101 for storing the plant material by having the function of supporting the protective member 30 and the function of regulating the space g2.

  Further, the protection member 30 is crowned from the front end surface 141 of the column portion 14, is engaged with the concave step surface 143 of the column portion 14 and is held at a predetermined position, and is made of a metal material such as stainless steel or aluminum. For this reason, even if a bending load or a shear load greater than the design load is applied to the specific column portion 14 for some reason, it becomes possible to distribute the load throughout the column portion 14 in the laying body. This has the effect of increasing the strength of the column portion 14.

  FIG. 9 is a perspective view of a laying body according to an embodiment of the present invention, and FIG. 10 is a front sectional view of the laying body of FIG. 9 and 10, the same reference numerals are given to the same components as those shown in FIGS. 1 to 8.

[Laying body]
9 and 10 includes the planting structure 1 described with reference to FIGS. 1 to 8, plant materials 41 and 42, customer soil 51, spacers 52, and nonwoven fabrics 53. .

  The plant materials 41 and 42 are in the form of sheets or mats, and well-known lawn mats can be used. The plant constituting the plant materials 41 and 42 is typically turfgrass, but is not necessarily limited to turfgrass, and may be a low-profile plant similar to turfgrass or so-called moss.

  The plant materials 41 and 42 are stored in the internal space (101) of the planting structure 1 in a direction in which the leaf tips can be exposed from the first opening 12, and are stored in the internal space (101). The surfaces of the plant materials 41 and 42 are covered with the protective member 30.

  When the plant materials 41 and 42 are so-called lawn mats, the lawn mats have a rectangular shape as a distribution standard that is almost common throughout the country, and have a longitudinal dimension of 360 mm and a width dimension of 300 mm, a longitudinal dimension of 350 mm, and a width dimension of 250 mm. There are things. Referring specifically to FIG. 9, the width dimension W1 of the planting structure 1 is previously matched with the longitudinal dimension L4 of the plant materials 41 and 42 (for example, 350 mm), and the longitudinal dimension L1 of the planting structure 1 is set. By making the width dimension W4 of the plant materials 41 and 42 twice (for example, 500 mm), the two plant materials 41 and 42 can be integrally held.

  The customer soil 51 is a culture soil filled in the internal space (101) for the purpose of stably rooting the roots of the plant materials 41 and.

  The spacer 52 is formed by molding a urethane resin having a porous structure (sponge structure) having water permeability and elasticity into a thin plate shape, a sheet shape, or a mat shape. It is arranged between. Assuming that the volume of the customer soil 51 repeatedly expands and contracts due to humidity and air temperature, the spacer 52 is raised in order to avoid a problem in which a gap is generated between the customer soil 51 and the nonwoven fabric 53 due to the expansion and contraction. It is used for.

The nonwoven fabric 53 is disposed between the other surface 112 of the first substrate part 11 and the spacer 52, and when discharging extra rainwater or the like from the internal space (101) through the second opening 13, When carrying the laying body or the like, it is possible to prevent a problem that the soil 51 is illegally leaked from the second opening 13. In addition, when the spacer 52 has water permeability, the nonwoven fabric 53 can be omitted by adjusting the thickness dimension of the spacer 52.
The column part 14 has the nonwoven fabric 53, the spacer 52, the customer land 51, and the plant materials 41 and 42 as described above in a state where the plant materials 41 and 42 are the internal space (101) for housing the plant material. It penetrates in the height direction T in order, and the front-end | tip part of the pillar part 14 is exposed on the surface of the plant material 41,42.

  11 to 13 are views showing a greening method according to an embodiment of the present invention. 11 to 13, the same components as those shown in FIGS. 1 to 10 are designated by the same reference numerals.

[Assembly method and greening method of laying body]
The advantages of the laying body shown in FIGS. 9 and 10 will be described from the viewpoint of the assembly method. First, referring to the process shown in FIG. 11, the main body member 10 is arranged on the work table or the ground surface so that the first opening 12 is on the upper side, and the inner space (101) of the main body member 10 is arranged. The non-woven fabric 53, the spacer 52, and the customer soil 51 are put in the order described above, and the plant materials 41 and 42 are placed in the internal space (101) in a direction that allows the leaf tips to be exposed from the first opening 12. It guides and penetrates the column part 14 in the height direction T of the plant materials 41 and 42. Each of the plurality of pillar portions 14 has a tapered shape and easily penetrates the plant materials 41 and 42. The pillar portion 14 penetrates the nonwoven fabric 53, the spacer 52, the soil 51, and the plant materials 41 and 42 in the height direction T, and the tip surface 141 is exposed on the surface of the plant materials 41 and 42. Thereby, the plant materials 41 and 42 are fixed to the main body member 10.

  The process of FIG. 12 is a process after the process shown in FIG. 11, in which the protection member 30 is disposed in the first opening 12 and the tip end portion of the column part 14 is inserted through the third opening 34. Thus, the opening edge of the third opening 34 is supported by the concave step surface 143. In a state where the protection member 30 is disposed inside the first opening portion 12, the one surface 31 of the protection member 30 is located at a position lower than the tip end surface 141 of the column portion 14, and more preferably, the first opening portion 12. It is mounted at a position lower than the opening edge of the. In the plant materials 41 and 42, the leaf tips are led to the outside through the first opening 12 and the through hole 33 according to the growing stage of the plant (for example, turfgrass).

  The process of FIG. 13 is a process after the process shown in FIG. 12, and is preferably performed on the construction target area S <b> 2 in an assembly factory or the like by the assembly method of the laying body described with reference to FIGS. 11 to 12. After the necessary number of laying bodies 100a to 100d are manufactured, the laying bodies 100a to 100d are transported to the construction site and continuously arranged vertically and horizontally along the construction target region S2. In the process of FIG. 13, the laying body 100d is positioned with respect to the male connection part 16 and the female connection part 17 of the adjacent laying bodies 100b and 100c, and the male connection part 16 and the female connection part 17 are raised. The laying bodies 100a to 100d are coupled to each other, for example, by dropping from the direction T.

[Effects of planting structure, laying body, and greening method using laying body of FIGS. 1 to 13]
The structure of the planting structure described with reference to FIGS. 1 to 8, the structure of the laying structure described with reference to FIGS. 9 and 10, and the greening method described with reference to FIGS. According to the following effects can be obtained.

  Since the planting structure 1 has the bottomed box-shaped main body member 10, the plant materials 41 and 42 can be stored in the internal space 101 through the first opening 12. Therefore, the laying bodies (100a to 100d) can be carried together in a state where the plant materials 41 and 42 are stored in the planting structure 1. And since the side surface of the structure 1 for planting is covered with the side wall part 15, the earth and sand etc. in the internal space 101 do not leak out to the outside, and the laying body 100 from the manufacturing plant to the construction site Transportation work and laying work at the construction site are facilitated.

  Moreover, since the side surface of the structure 1 for planting is covered with the side wall part 15, even if it arrange | positions the structure 1 for planting connected vertically and horizontally, the plant in the adjacent structure 1 for planting The passage of the roots of the materials 41 and 42 is obstructed by the side wall 15. Therefore, for example, after a long period of time has elapsed since laying work, when some of the planting structures 1 are replaced, for example, because the lawn inside the planting structure 1 has died, the grass roots are damaged. The rearrangement can be easily performed. Furthermore, since the laying bodies (100a to 100d) can be rearranged even after the construction, the number of on-site work processes can be reduced, the construction period can be made more efficient, and the construction cost can be reduced.

  Since the plant materials 41 and 42 are stored in the internal space 101 in such a direction that the leaf tips can be exposed from the first opening 12, the leaf tips of the plant materials 41 and 42 are exposed to the outside through the first opening 12. A green landscape is produced by exposing to.

  On the surface of the plant materials 41 and 42, the tip end portion of the column portion 14 is exposed. According to this structure, the space g1 according to the height difference is ensured between the front end surface 141 of the column portion 14 and the surfaces of the plant materials 41 and 42. Therefore, external forces (F1, F2) such as a pedestrian's stepping pressure, an automobile load, and friction received from a rotating tire can be supported by the tip surface 141, and the surfaces of the plant materials 41, 42 can be protected from the external force. . Specifically, as shown in FIG. 14, even if the automobile tire 6 contacts the tip surface 141 of the column portion 14, a space g <b> 1 is secured between the tire 6 and the plant materials 41 and 42. As a result, there is no problem that the surfaces of the plant materials 41 and 42 are pressed and compacted by the load on the automobile.

  In addition, the plurality of pillar portions 14 are dispersedly arranged in a matrix on the surfaces of the plant materials 41 and 42, and the plurality of tip surfaces 141 constitute an integral tread surface S1, so that the rotational force F2 of the tire 6 is obtained. In other words, the frictional force F2 generated in the tangential direction at the contact surface between the rotating tire 6 and the column portion 14 is received by the tip surface 141 and the tread surface S1, and the surfaces of the plant materials 41 and 42 Can be reliably protected from the frictional force F2.

  Since the space g1 is formed between the one surface 31 of the protection member 30 and the tip surface 141 of the pillar portion 14, the leaf tips of the plant materials 41 and 42 exposed to the outside from the through hole 33 are subjected to frictional force. When F2 is received, there is no inconvenience of being clipped by being pinched by the opening edge of the through hole 33. Therefore, the state where the leaf tips of the plant materials 41 and 42 are always exposed on one surface of the laying body 100 can be maintained, and a green landscape can be produced.

  Moreover, as shown in FIG. 15, even if the pedestrian's shoe sole 70 contacts the tip surface 141 of the pillar portion 14, there is a space g1 between the shoe sole 70 and the surfaces of the plant materials 41 and 42. There is no problem that the surfaces of the plant materials 41 and 42 are pressed and solidified by the walking pressure of the pedestrian.

  Since the column portion 14 is formed integrally with the first substrate portion 11, it has excellent mechanical strength against external forces (F1, F2). Further, since the plurality of column portions 14 project in a matrix shape, the external forces (F1, F2) can be dispersed and supported by the respective front end surfaces 141. Therefore, the plant material can be reliably protected from the external force (F1, F2).

  Since the plurality of pillars 14 project in a matrix shape, the roots of the plant materials 41 and 42 avoid the pillars 14 to freely grow the internal space 101, and rainwater and the like avoid the pillars 14 and are internal. It moves freely in the space 101. Therefore, it is possible to reduce plant material growth costs and maintenance management costs after the laying body 100 is laid.

  In addition to the basic functions of the planting structure 1 and the laying body 100 described above, the greening method according to the present invention is characterized by having a protective member 30 as a measure against the heel portion of women's shoes. That is, the protective member 30 has a plurality of through holes 33 in the surface, covers the first opening 12, and is supported by the tip end portion of the column portion 14 in a state of covering the first opening 12. Yes. According to this structure, the leaf tips of the plant materials 41 and 42 are exposed to the outside through the through hole 33, and a green landscape can be produced.

  In the protection member 30, the tip end portion of the column portion 14 is guided to the third opening portion 34, and the opening edge of the third opening portion 34 is hooked on the concave step surface 143. Since the space g2 between the first substrate portion 11 and the protective member 30 is regulated according to the height position T142 of the diameter reduction portion 142, various thickness dimensions can be obtained by adjusting the height position T142 in advance. The plant materials 41 and 42 that are included can be integrally sandwiched between the first substrate portion 11 and the protection member 30. Therefore, commercially available lawn mats can be used directly as the plant materials 41 and 42.

  The through hole 33 of the protective member 30 has an opening shape through which the tip of the heel portion of the women's shoe cannot pass and a passing dimension, and the minimum passing hole diameter D33 is preferably 10 mm or less. Usually, since the diameter of the tip of the heel portion 71 of the women's shoes is larger than 10 mm, even if the pedestrian walks on the laying body 100 wearing the women's shoes having the elongated heel portions 71 such as pumps and high heels, the heel The problem that the part 71 is immersed in the planting structure 1 is avoided. In the embodiment of FIG. 15, if the protection member 30 is not provided, the brim 71 penetrates the plant materials 41 and 42, and further penetrates the soil 51, the spacer 52, and the nonwoven fabric 53 to the ground surface 8. Reach. That is, the immersive distance of the heel part 71 is increased by the height dimension of the planting structure 1 and the immersive distance of the heel part 71 is larger than when walking directly on the grass with high heels. The balance is lost, and an unexpected fall accident occurs.

On the other hand, in the present invention, by covering the first opening 12 with the protection member 30, the pedestrian's shoe sole 70 is supported by the distal end surface 141 of the column portion 14, and the distal end portion of the heel portion 71. The immersion distance is stopped up to one surface (31) of the protective member 30. Therefore, while protecting the plant materials 41 and 42 from the heel part 71 of women's shoes, the fall accident caused by the heel part 71 immersing in the inside of the structure 1 for planting is prevented beforehand, and safety of a pedestrian is improved. Can be secured.
Furthermore, the protection member 30 is crowned from the front end surface of the column part 14, is engaged with the column part 14 and is held at a predetermined position, and is made of a metal material such as stainless steel or aluminum. Even if a bending load or a shearing load greater than the design load is applied to the column portion 14 for some reason, the load can be distributed throughout the column portion 14 in the laying body, and as a result, the column portion of the laying body The strength of 14 can be increased.

  Unlike the planting structure 1 described with reference to FIGS. 1 to 13 and the laying body 100 using the structure 1, a method of driving a skewer into a conventional lawn mat and fixing it to the ground surface (Patent Document 1) )) Has no protective function against the surface of the lawn mat, so solve the problem peculiar to the lawn of the parking lot where the lawn is damaged by the load F1 and frictional force F2 of the car I can't. In addition, assuming the construction of a parking lot with a large site surface area, the number of on-site work processes such as winding turf placement work and skewering work increases, leading to a longer construction period and higher construction costs.

  In addition, the lattice-shaped resin-made plant growth protection board (see Patent Document 2) provided with treading pressure resistance protrusions does not have sufficient mechanical strength to withstand the heavy loads of large vehicles such as trucks. Prior to the process of arranging the growth protection panel, a process of cultivating the lawn on the ground surface, which is the construction surface, or a process of laying a lawn mat on the ground surface is required. Longer construction costs are incurred.

  Furthermore, in a lawn protection pallet (see Patent Document 3) in which a plurality of cylinders are connected in a net to provide a lawn storage unit for storing soil and lawn inside each cylinder, the lawn mat is cut into small pieces. The work of arranging in each cell is troublesome. In particular, when a construction for a parking lot having a large site surface area is assumed, the cost becomes high.

[Assembly method and greening method of laying body]
First, referring to FIG. 28, the first main body member 10 is arranged on the work table or the ground surface so that the one surface 112 faces down, and the plant materials 41 and 42 are turned upside down with respect to the other surface 112. Then, the leaf tips are guided from the second opening 13 in a direction in which they can be exposed, and the pillar portion 14 is penetrated in the height direction T of the plant materials 41 and 42. Each of the plurality of pillar portions 14 has a tapered shape and easily penetrates the plant materials 41 and 42. A protective member 30 is attached to the second opening 13 in advance, and the second opening 13 is covered with the protective member 30.

  29 and 30, the pillar portion 14 penetrates the plant materials 41 and 42 in the height direction T, and the tip surface 141 is exposed on the root surface side of the plant materials 41 and 42. , 42 are fixed to the first body member 10. The plant material 41, 42 has a leaf tip from the other surface (32) to the one surface (31) through the second opening 13 and the through hole 33 of the protective member 30 according to the growing stage of the plant (for example, turfgrass). Derived.

  The process of FIG. 31 is a process after the process shown in FIGS. 29 and 30, and the customer soil 51 is put on the root surfaces of the plant materials 41 and 42, more preferably the spacer 52 and the nonwoven fabric 53. Thus, the second main body member 20 sandwiches the entire surface of the customer land 51. The input amount of the soil 51 and the thickness dimension of the spacer 52 and the nonwoven fabric 53 can be determined in advance within the range of the projecting dimension (T14) of the column part 14. After the plant materials 41 and 42, the land 51, the spacer 52, and the nonwoven fabric 53 are put into the first main body member 10 in the order described above, and the first and second main body members 10 and 20 are combined, Flip upside down so that one surface 111 is on top.

The laying bodies 100a to 100d are fitted to each other by dropping from the direction T or the like.

[Effects of planting structure, laying body, and greening method using laying body of FIGS. 16 to 32]
The structure of the planting structure described with reference to FIGS. 16 to 25, the structure of the laying structure described with reference to FIGS. 26 and 27, and the greening method described with reference to FIGS. According to the following effects can be obtained.

Since the planting structure 1 has the bottomed box-shaped first main body member 10, the plant materials 41 and 42 can be stored in the internal space 101 through the first opening 12. Accordingly, the laying bodies (100a and 100b) can be carried in a state where the plant materials 41 and 42 are housed in the planting structure, and are transported from the assembly site to the construction site, the construction target area S2 at the construction site. Construction efficiency such as laying work is improved.
The first substrate portion 11 of the first main body member 10 has a second opening 13. The plant materials 41 and 42 are stored in the internal space 101 in such a direction that the leaf tips can be exposed from the second opening 13. According to this structure, the leaf tips of the plant materials 41 and 42 are exposed to the outside through the second opening 13, and a green landscape can be produced.

  The first substrate unit 11 has a plurality of second openings 13. Usually, if the opening area of the 2nd opening part 13 is made small, the plant materials 41 and 42 can be protected from external force. However, if the opening area of the 2nd opening part 13 is made small, the exposure area of the plant materials 41 and 42 will decrease by that much, and it will become impossible to produce a green landscape. Therefore, in the present invention, the plurality of second openings 13 are arranged in a matrix on the first substrate portion 11, thereby reducing the opening area of each second opening 13 and overall. Maximum opening area is secured. Therefore, the conflicting request | requirement of protecting the plant materials 41 and 42 from external force and realization of the greened landscape can be achieved simultaneously.

  In the first and second main body members 10 and 20, the first and second substrate portions 11 and 21 are arranged to face each other, and the tip end portion of the column portion 14 is fitted in the fitting recess 23. According to this structure, an internal space 101 having a space g2 corresponding to the projecting dimension (T14) of the column portion 14 is formed between the opposing surfaces of the first and second main body members 10 and 20. Therefore, by storing the plant materials 41 and 42 in the internal space 101, the plant materials 41 and 42 can be held by the first and second main body members 10 and 20. Furthermore, by adjusting the plate surface shapes of the first and second substrate portions 11 and 21 in advance, various planar plant materials 41 and 42 can be held in the internal space 101.

  The column portion 14 has a tapered shape having a flat distal end surface 141 at the distal end portion, and is integrally formed with the first substrate portion 11, and a plurality of the column portions 14 project from the other surface 112 in a matrix shape. Therefore, even if a load is applied to the first surface 111 of the first substrate portion 11, the load is distributed and supported by the plurality of column portions 14, and the first and second main body members 10 and 20 are supported. The problem that the space g2 is reduced can be avoided. Specifically, as shown in FIG. 33, even if the vehicle upper load F1 is applied to the first surface 111 of the first substrate portion 11, the space g2 is kept constant, and the vehicle upper load F1 The problem that the plant materials 41 and 42 are pressed does not occur.

  In addition, since the surfaces of the plant materials 41 and 42 exposed in the second opening 13 are surrounded by one surface 111 of the first substrate portion 11, the tire 6 is mainly used as shown in FIG. The surface 111 of the plant material 41, 42 can be protected from the frictional force F2.

  Furthermore, since there is a space g3 corresponding to the protrusion 113 between the tire 6 and the surfaces of the plant materials 41 and 42, and the plurality of protrusions 113 constitute an integrated tread surface S1, frictional force F2 is received by the protrusion 113 and the tread surface S1, and the surfaces of the plant materials 41 and 42 can be protected from the frictional force F2. According to this structure, the leaf tips of the plant materials 41 and 42 exposed to the outside from the through hole 33 of the protective member 30 are clipped by being sandwiched between the opening edges of the through hole 33 when receiving the frictional force F2. There will be no inconvenience. Therefore, the state where the leaf tips of the plant materials 41 and 42 are always exposed on one surface of the laying body 100 can be maintained, and a green landscape can be produced.

  Further, in the laying body 100, the pillar portion 14 penetrates the plant materials 41 and 42, so that the first body member 10 and the first substrate portion 11 are planted by the pillar portion 14 and the plant materials 41 and 42. And integrated. Thereby, when the frictional force F <b> 2 is applied to the first substrate unit 11, a braking force due to the weight of the plant materials 41 and 42 acts on the first substrate unit 11. Accordingly, the first main body member 10 is prevented from moving illegally such as leaving the plant materials 41 and 42 and moving horizontally, and the plant by the first main body member 10 and the first substrate unit 11 is suppressed. The protection state of the materials 41 and 42 is maintained well.

  Since the pillar part 14 protrudes inside the internal space 101, for example, the roots of the plant materials 41 and 42 avoid the pillar part 14 and freely grow the internal space 101, and rainwater or the like Avoid the internal space 101 and move freely. Therefore, it is possible to reduce plant material growth costs and maintenance management costs after the laying body 100 is laid.

  The plant materials 41 and 42 are stored in the internal space 101 in a state of being sandwiched between the first and second main body members 20 and 20. Here, since the 1st main body member 10 has the side wall part 15, and the side wall part 15 has stood up according to the protrusion dimension (T14) of the pillar part 14 from the periphery of the other surface, the structure 1 for planting These side surfaces are covered with the side wall 15. According to this structure, the plant materials 41 and 42 can be carried together with the planting structure 1, and the carrying work of the laying body 100 from the manufacturing factory to the construction site and the laying work at the construction site are facilitated. .

  The laying body of FIGS. 16 to 34 differs from the laying body of FIGS. 1 to 15 in that the second opening 13 for exposing the leaf tips of the plant materials 41 and 42 is covered with a protective member 30. Similar effects can be obtained. For example, the plant materials 41 and 42 are in the form of a sheet or a mat, and are stored in the internal space 101 in a direction in which the leaf tips can be exposed from the second opening 13. , 42 is covered with a protective member 30. According to this structure, the leaf tips of the plant materials 41 and 42 are exposed to the outside through the through-holes 33 of the protective member 30, and a green landscape can be produced.

  The through hole 33 of the protective member 30 has an opening shape through which the tip of the heel portion of the women's shoe cannot pass and a passing dimension, and the minimum passing hole diameter D33 is preferably 10 mm or less. Usually, since the diameter of the tip of the heel portion 71 of the women's shoes is larger than 10 mm, even if the pedestrian walks on the laying body 100 wearing the women's shoes having the elongated heel portions 71 such as pumps and high heels, the heel The problem that the part 71 is immersed in the planting structure 1 is avoided. In the embodiment of FIG. 34, if there is no protective member 30, the brim portion 71 penetrates through the plant materials 41 and 42, and further penetrates the soil 51, the spacer 52, and the nonwoven fabric 53 to reach the ground surface 8. . That is, the immersive distance of the heel part 71 is increased by the thickness of the planting structure 1 and the immersive distance of the heel part 71 is increased, compared to a case where the heel is directly walked on the lawn with high heels. Will cause an unexpected fall.

  On the other hand, in the present invention, by covering the second opening 13 with the protection member 30, the immersion distance of the distal end portion of the heel portion 71 is reduced in a state where the shoe back 70 of the pedestrian is supported by the protruding portion 113. Up to one surface (31) of the protection member 30 is secured. Therefore, while protecting the plant materials 41 and 42 from the heel part 71 of women's shoes, the fall accident caused by the heel part 71 immersing in the inside of the structure 1 for planting is prevented beforehand, and safety of a pedestrian is improved. Can be secured.

  The protective member 30 has a U-shape, and the angle formed by the tread surface 35 and the first leg portion 36 and the angle formed by the tread surface portion 35 and the second leg portion 37 are both slightly larger than the right angle. It is desirable to do. By making the shape of the protective member 30 into the shape described above, the protective member 30 is disposed so as to be surrounded by the four protective members 30 around the pillar portion 14 of the first main body member 10, thereby filling the laying body. Therefore, the strength of the column portion 14 of the first main body member 10 can be increased, and as a result, the rigidity of the entire laying body can be increased.
