Summary of the Invention

Problems to be Solved by the Invention

[0004] The weed control construction method described in Patent Document 1 is described as "a construction method of using roof tiles of a roofing material capable of shading and a structural member capable of shading directly on the ground in the weed control area to form a shading structure with a high weed control effect...". However, since one end of the tiles to be constructed is directly installed on the ground, the preparation of the land in the weed control area is insufficient. When there are irregularities or undulations on the ground, it is difficult to accurately form a shading structure. Also, when constructing on soft ground or sloping ground, the occurrence of tile displacement, sinking, etc. is predicted, and it becomes difficult to accurately maintain the shading structure. For this reason, when sunlight shines in, plants perform photosynthesis and grow, so weeds cannot be suppressed over a long period. The weed control construction method described in Patent Document 1 is inconvenient for construction in places with insufficient preparation, soft ground, sloping ground, etc.

[0005] The object of the present invention is to eliminate the above-mentioned inconveniences, and even if the weeding construction site is undeveloped land, soft ground, or a steep slope, it can be easily and accurately constructed, and a light-shielding structure with a high weeding effect over a long period can be formed, creating an environment where plants cannot perform photosynthesis. The present invention provides "flat tiles, a gantry, and a weeding construction method thereof".

[0008] The "light-shielding structure" among the elements constituting the present invention is defined as a structure that places flat tiles on a gantry to form a structure that blocks sunlight from the sky and prevents sunlight from entering from the side.

[0009] To achieve the object, the gist of the invention according to claim 1 is to use a plurality of angle steel materials, process them into frames 2 and 3, and form a pedestal 1 with horizontal bars 4, 5, 6, 7 formed by welding and processing the angle steel materials back to back. On the pedestal 1, a plurality of flat tiles 13 provided with protrusions are placed, positioned, fitted (loosely fitted), clamped, and fixed, so that a light-shielding structure integrating the flat tiles and the pedestal can be formed. This is a weed control construction method.

[0010] Among the present invention, the gist of the invention according to claim 2 is that in the flat tile 13 having light-shielding properties according to claim 1, on the side surfaces of the head 1b and the butt 1a of the flat tile 13 whose surface 111 is flat, one or more protrusions 14, 15, 16 are provided for positioning and preventing the tile from being blown off.

The flat tile (13) is characterized by this.

[0011] Among the present invention, the gist of the invention according to claim 3 is that the pedestal 1 according to claim 1 comprises the structural members shown in FIG. 7. A plurality of hole portions and long hole portions are provided in the flat portions of the two frames 2 and 3, and they are arranged in parallel so as to face each other left and right.

While holding it, tighten and fix the hole portions 12a of the left and right frames 2 and 3 and the hole portions 12b of the cross bar with their respective bolts and nuts, and perform additional tightening and fixing of the previously temporarily fastened left and right bolts and nuts. The third step; next, the construction method for the second row and subsequent rows is to perform construction in sequence up to the construction range in the same manner as the first row, and form a light-shielding structure on a plane integrated across the entire gantry. The fourth step; It is a weeding prevention construction method that includes and constructs.

[0013] Since the present invention is configured as described above, it has the following effects.

Effects of the Invention

[0014] According to the weed control construction method described in claim 1, by using a gantry formed by processing angle steel, flat tiles provided with a plurality of protrusions are positioned, fitted, clamped, and fixed at the openings of the crossbars. An integrated light-shielding structure can be formed on the gantry having such functions. Therefore, plants cannot perform photosynthesis under the gantry as shown in Fig. 1, 1) of Fig. 13, and 1) of Fig. 19, and a weed control effect of suppressing the growth of weeds can be exerted.

[0015] According to 4) of Fig. 11, the light-shielding flat tile described in claim 2 has a flat surface and one or more protrusions provided on the side surface. By fitting it according to the openings provided on the crossbars and the frame, the effect that the tile does not come off the gantry can be achieved. Also, according to Figs. 2 and 3, since the left side surface is provided with an overlap portion and the right side surface is provided with an underlap portion, adjacent flat tiles can be connected, and a planar light-shielding structure can be formed over a wide range. Further, according to the cross-sectional view E-E of Fig. 12, the overlapping portion of the laps can prevent sunlight even when the overlapping width L is about 5 mm to 10 mm. Therefore, a large plane can be taken and it is also effective in terms of strength. On the other hand, according to Fig. 3, on the back surface, contour ribs are provided along the outer periphery over the entire circumference, and one or more trapezoidal ribs are provided within the inner contour of the ribs. Thus, the strength of the tile body can be increased and the weight reduction of the tile body can be achieved. Furthermore, at the four corner portions of the head and the butt of the flat tile, a part of the contour rib is cut off to provide a stepped portion, which is formed into a relief shape for the fastening member. Therefore, according to the cross-sectional view F-F of Fig. 12, it does not interfere with the fastening between the crossbar and the frame. Also, according to the cross-sectional view A-A of Fig. 5, since the front and back surfaces of the flat tile have parallel surfaces, an integrated light-shielding structure without rattling can be formed even when the flat tile is placed on the gantry. From the above, when such a weed control flat tile and a weed control gantry are used, the necessary features and functions of each other can be exerted. As a result, the plants under the gantry cannot perform photosynthesis, and the environment is not conducive to the growth of weeds, and a weed control effect can be exerted.

[0016] According to the pedestal described in claim 3, by using a highly rigid pedestal formed of angle steel, it has the function of placing, positioning, fitting, clamping, and fixing the flat tiles described in claim 2 on the pedestal. If the procedure shown in Fig. 11, which is the base of the "flat tile, pedestal, and its weed control construction method" of the present invention, is followed, a planar light-shielding structure integrating the flat tile and the pedestal can be formed on one side of the pedestal. Thus, since light does not reach under the pedestal and the photosynthesis of plants is suppressed, a high weed control effect is achieved.

[0017] Furthermore, since the light-shielding structure is installed on the pedestal and does not directly contact the ground, air and water do not stagnate, and it has breathability, so the breeding of various bacteria is less likely to occur, and it has the effect of not adversely affecting the soil environment.

[0018] Also, preferably, if anchor bolts 998 are embedded and fixed on the construction surface where a highly rigid square frame is to be installed, as shown in f) of 3) in Fig. 13 or i) in Fig. 22, and then fixed using the hole 999 made in the pedestal in Fig. 1, even if the "weed control construction site is unmaintained land, soft ground, or a steep slope", a light-shielding structure with a high weed control effect can be easily and accurately constructed.

[0019] According to the weed control construction method described in claim 4, by using flat tiles 13 with light-shielding properties, placing, positioning, fitting, clamping, and fixing the flat tiles on the pedestal 1. As shown in Figs. 1 and 11, insert the protrusions provided on the flat tiles into the openings of the opposing horizontal bars, and move the horizontal bars to tighten the frame and the horizontal bars with bolts and nuts shown in the F-F cross-sectional view of Fig. 12. By executing this method, even without experience, construction can be easily, accurately, and quickly carried out.

[0020] Also, as shown in the cross-sectional view taken along line E-E of FIG. 12, by aligning the underlap portion on the 1c side of the laid flat tile 13 and the overlap portion on the 1d side of the flat tile 13 placed second, and constructing in the same manner sequentially, a continuous planar light-shielding structure can be formed over the entire area of the gantry. As a result, the plants under the gantry cannot perform photosynthesis, creating an environment where weeds are less likely to grow and enabling the exhibition of a weed control effect.

[0021] Since the weed control construction method according to the present invention exhibits excellent effects as described above, even if the weed control construction site of the present invention is unimproved land, soft ground, or a steep slope, it can be easily and accurately constructed, and a light-shielding structure with a high weed control effect over a long period can be formed. Therefore, the object of the present invention, "providing a flat tile, a gantry, and a weed control construction method thereof," can be achieved. From this, the present invention can be suitably used as a construction method for land where the growth of weeds is to be suppressed.

Mode for Carrying Out the Invention

[0023] Hereinafter, with reference to the attached drawings, the most preferred embodiments of the present invention will be described in detail. It should be noted that the embodiments described below are merely examples that embody the present invention and do not limit the technical scope of the present invention. FIG. 1 is an overall perspective view of the present invention, FIGS. 2 to 6 are drawings related to flat tiles, FIGS. 7 to 10 are drawings related to the gantry, FIGS. 11 to 12 are drawings showing the relationship between the flat tiles and the gantry, FIGS. 13 and 19 are examples of construction on an inclined surface according to the embodiment, FIGS. 14 to 17 are drawings related to the gantry on the inclined surface, FIG. 18 is an example of a cut tile used for the inclined portion, and FIGS. 20 to 22 are drawings related to special cases.

[0024] (1) Flat tile In the flat tile, FIG. 1 is an overall perspective view of the assembly process of the light-shielding structure seen from the front side, FIG. 2 is a perspective view of the flat tile 13 constituting the light-shielding structure, FIG. 3 is a perspective view of the back surface 112 of the flat tile 13, FIG. 4 is a plan view of the flat tile 13, FIG. 5 is a sectional view taken along the lines A-A and B-B of FIG. 4, and FIG. 6 is a view showing the views in the directions of the arrows (a), (b), (c), and (d) of FIG. 4. The flat tile 13 in FIG. 2 according to the present invention has a square shape and a plane on the plane (exposed surface) 111 that receives sunlight, a protrusion 14 is provided on the head 1b side, and protrusions 15 and 16 are provided on the butt 1a side. These protrusions are provided so that the flat tile 13 is not blown off by strong winds or the like or peeled off even on a steep slope. The protrusions shown in 3) and 4) of FIG. 11 are fitted, clamped, and fixed in the openings (8a, 8b) provided in the horizontal bars of FIGS. 7 and 9 constituting the gantry 1 to have a structure that cannot move physically. The height of this protrusion is preferably less than twice the thickness t (mm) of the angle steel material forming the horizontal bar in terms of strength and moldability.

[0025] Then, as shown in Fig. 6, on the side 1d side of the flat tile 13, mating-shaped overlap portions 21, 22, 23 are provided, and on the side 1c side, mating-shaped underlap portions 18, 19, 20 are provided. Therefore, as shown in the cross-sectional view taken along line E-E in Fig. 12, adjacent flat tiles can be connected. Also, the lap width L (the mated portion) only needs to be such that sunlight does not reach under the gantry. Thus, even if it is about at least 5 mm to 10 mm, sunlight can be blocked. For this reason, the working (light-shielding) area of the plane can be increased, and the strength can also be increased.

[0026] Next, Fig. 3 is a perspective view of the back surface 112 of the flat tile 13. On the back surface 112, a contour rib 24 is provided along the outer periphery of the flat tile 13 over the entire circumference. Inside the inner contour of the rib, as shown in the cross-sectional view taken along line B-B in Fig. 4, three trapezoidal ribs 26 are provided, enabling weight reduction of the tile body while maintaining the strength of the tile body. Further, at four corners of the flat tile 13, by cutting off a part of the contour rib 24 to provide a stepped portion 17 of a predetermined amount, further weight reduction and clay saving can be achieved. And this step is made into a structure such that the bolt for fastening the gantry and the cross bar does not interfere with the flat tile placed on the gantry as shown in the cross-sectional view taken along line F-F in Fig. 12, so that the gantry and the placed flat tile can be integrated.

[0027] The flat tile 13 shown in Figs. 4, 5, and 6 is a flat tile having light-shielding properties. On the head side 1b of the flat tile 13 with a flat surface 111, one protrusion 14 is provided, and on the side surface of the butt side 1a, two protrusions 15 and 16 are provided. Therefore, by fitting, clamping, and fixing it to the openings (8a, 8b) provided in the cross bar, Figs. 4) in the cross-sectional view of Fig. 11 and the cross-sectional view taken along line H-H in Fig. 12 are views of the base showing the fitting state between the protrusion of the flat tile and the openings provided in the cross bar. Thus, since the flat tile 13 has a structure that does not physically come off from the gantry, it has the effect of preventing the flat tile from shifting, rattling, or being blown off.

[0028] Figure 4 is a plan view of the flat tile 13. The size of the flat tile 13 used in this embodiment is set to be equivalent to that of the existing flat F-shaped tile. The vertical dimension is 35 cm and the horizontal dimension is 34.5 cm. Among them, even if the lap width is 1 cm, the working area (light shielding) is 35×33.5≒0.117m 2 That is. Therefore, for 3.3m 2 about 3.3÷0.117≒28 pieces are required. Incidentally, in the case of the existing F-shaped tile, the working length is 35 cm → 28 cm, the working width is 34.5 → 30.5 cm, and the working area is 28×30.5≒0.085m 2 That is, for 3.3m 2 about 3.3÷0.085≒39 pieces are required. Therefore, the flat tile for weed control of the present invention can be made into a light shielding structure having a plane 1.39 times that of the conventional flat tile even with the same number of construction pieces. However, the present invention is not limited to this embodiment, and the material, shape, size, thickness, etc. can be appropriately selected and changed within the scope of the present invention according to the purpose and application.

[0029] Also, in the gantry 1, as shown in the perspective view of FIG. 1, the plan view of FIG. 8, and the cross-sectional view of FIG. 10, it is preferable to screw or weld-bond the flat steel material 11 to the center part of the horizontal crossbars. By increasing the rigidity of the gantry and widening the installation area of the flat tiles, it is difficult to break even when stepping into the structure during the construction or maintenance of the light shielding structure, and it is effective in preventing stepping cracks.

[0030] In addition, for the construction of the inclined surfaces of surfaces J and K in FIG. 13, an obliquely shaped flat tile is required. The back surface of the flat tile is provided with a trapezoidal rib 26. As shown in the cross-sectional view taken along line B-B of FIG. 5, no matter at what angle it is cut, the front and back of the flat tile are parallel. Therefore, a structure without rattling can be formed even when placed on the gantry. 1) in FIG. 18 shows the cutting angles of the tiles placed on the gantry for construction on the inclined surface J and the inclined surface K of FIG. 13. Cut and fit according to each gantry to form a structure without gaps. Here, preferably, an adhesive with adhesiveness is applied and filled to the entire circumference and the bottom surface of the cut tile, so that a light shielding structure that does not peel off can be formed. More preferably, as shown in (a) of FIG. 17, an L-shaped angle or the like can be screwed to prevent it from being physically displaced.

[0031] The material of the flat tile 13 used in this embodiment is preferably a light-shielding material with good formability and strength, and is a clay material with weather resistance. Concrete materials, synthetic resin materials, or glass materials can also be used. In addition, the size, thickness, and shape of the tile can be changed according to the application, and a part of the embodiment can be changed and implemented within the limit that the effects of the present invention are not significantly impaired.

[0032] In addition, as shown in the A-A cross section of FIGS. 4 and 5, since the flat tile 13 is square and the front and back are parallel, a plurality of flat tiles can be compactly packed, are easy to load, and exhibit the effect of preventing cracks and chips during transportation.

[0033] (2) Stand FIG. 7 is a schematic diagram of the members constituting the stand, FIG. 8 is a plan view of the stand 1, FIG. 9 is a view taken in the direction of arrow e of FIG. 8, FIG. 10 is a C-C cross-sectional view of FIG. 8, FIG. 11 is a displacement cross-sectional view of procedures 1), 2), 3), and 4) showing the movement of the horizontal bar, placement, fitting, clamping, and fixing of the flat tile when placing the flat tile, and FIG. 12 shows the cross-sectional views of E-E, F-F, G-G, and H-H of FIG. 1. To form the stand 1, angle steels 2 and 3 among the members in FIG. 7 and horizontal bars 4, 5, 6, and 7 on which the flat tiles can be placed are prepared, and a plurality of hole portions 12a and long hole portions 9 are provided at predetermined positions on the flat portions of the two angle steels 2 and 3, and they are arranged in parallel so as to face each other left and right. Next, the angle steels are joined back to back, a plurality of opening portions 8a and 8b are provided on the vertical surfaces thereof, and horizontal bars 4 and 7 provided with a plurality of hole portions 10 and 12b on the flat portions thereof are arranged with the horizontal bar 4 at the lower part of the left and right angle steels and the horizontal bar 7 at the upper part, and are fastened with bolts and nuts to form a square frame as shown in FIG. 8, and then the horizontal bars 5 and 6 are provided to form the stand 1.

[0033] By using a highly rigid stand formed of angle steel, a plurality of flat tiles can be placed, and a large light-shielding structure can be formed by adding stands as needed. This will be described in Embodiments 1 to 3.

[0034] And what is characteristic of this pedestal is that, as shown in Fig. 11, it is positioned in accordance with the openings 8a and 8b shown in Fig. 9(e) of the crossbar, where the protrusions 14 and 15, 16 provided on the head 1b and the butt 1a of the flat tile 13 are provided on the crossbar. After moving the crossbar to fit and clamp the protrusions of the flat tile, it has a structure with the function of being fastened with bolts and nuts.

[0035] The function and procedure of this pedestal will be described with reference to the cross-sectional view in Fig. 11. The process of 1) in Fig. 11 is to pass the embedded anchor bolts through the holes 999 of the frames 2, 3, the crossbar 4 and the crossbar 7 that form the frame, and tighten and fix them with nuts. Next, the crossbar 5 is placed, and the holes 10 provided on the left and right of the crossbar 5 are aligned with the long holes 9 of the frame, and temporarily tightened loosely using bolts, nuts and washers.

[0036] The process of 2) in Fig. 11 is to move the crossbar 5 temporarily fastened to the frames 2 and 3 in the left (upper) direction until the bolt catches and stops at the left end of the long hole, so that the flat tile A in Fig. 1 can be placed. Since the flat tile has the escape shape 17 of the bolt or nut shown in Figs. 2 and 3, it can be placed without interference.

[0037] The process of 3) in Fig. 11 is to move the flat tile A in the right (lower) direction to fit the protrusion 14 into the opening 8b of the crossbar 4, and move it until the end face 1b of the flat tile hits. Subsequently, the flat tiles B... to the flat tile C in the construction range of the first row are moved in the same way until the end face 1b of the flat tile hits, and placed.

[0038] The process of 4) in Fig. 11 is to move the crossbar 5 to the right while placing the butt of the flat tile on it, fit the protrusions 15 and 16 of the flat tile into the opening 8a of the crossbar 5, and move it to the right until the crossbar 5 cannot move while positioning and fitting (loosely moving). While pressing, tighten and fix by aligning the holes between 12b provided on both end faces of the crossbar 5 and the frame 12a with tightening bolts and nuts. Subsequently, tighten the bolts and nuts temporarily tightened in the process of 1) in Fig. 11 more tightly, and firmly fix them to complete the construction of the first row.

[0039] For the columns starting from the second column, by repeating the steps 1) to 4) of FIG. 11 in the same manner, a planar light-shielding structure integrated over the entire gantry can be formed. As described above, since the weed control construction method of the present invention is a method of fitting the protrusions of the flat tiles into the openings provided at the determined positions of the gantry, it can be easily and accurately assembled even without experience.

[0040] In addition, by using this robust gantry, even on land where the installation location is not well-prepared, land with some unevenness, soft ground, or a steep slope, as long as the installation location for fixing the gantry is prepared to be securely installed with anchor bolts or the like as shown in 1) of FIG. 11 or 3) of FIG. 13, it can be safely constructed and is also effective from the safety aspect of being released from dangerous mowing on steep slopes.

[0041] In addition, the steel material used for the gantry is preferably angle steel material subjected to rust prevention treatment. More preferably, after processing the hole parts, long hole parts, and rectangular openings, an anti-rust agent is applied to prevent rust from occurring on the gantry and to maintain the performance over a long period.

[0042] (3) Weed control construction method Since there are various embodiments of the weed control construction method in this example, representative embodiments will be specifically described below.

[0043] Embodiment 1: When constructing on flat ground such as solar power generation The construction procedure is to prepare a gantry equipped with the required number of flat tiles 13, a frame, and horizontal bars, level the area to be weed-controlled, determine the location for installing the gantry. For small-scale construction, it is preferable to bury concrete blocks as shown in 1) of FIG. 11 at the four corners of the construction area, insert anchor bolts 998, and solidify them with cement or the like before construction. Specifically, it is preferable to start the construction by passing the anchor bolts 998 through the four hole parts of the 999 parts of the frames 2, 3, the horizontal bars 4, and the horizontal bar 7 in FIG. 7 of the drawing, inserting washers 72, and fixing them with nuts 71 as shown in 1) of FIG. 11 of the drawing.

[0045] For the weed control construction on flat ground such as solar power generation in this embodiment, it is preferable to connect using the unit pedestal (lateral expansion) in 2) of Fig. 13 and the method of the unit pedestal (longitudinal expansion) in 2) of Fig. 19, and unitize by incorporating flat tiles as a structure. This enables efficient construction, shortens the construction period, and reduces costs.

[0046] By implementing the weed control construction method described in paragraph 0012 of this specification for the method of placing flat tiles on the pedestal, a light-shielding structure integrating the pedestal and flat tiles can be formed on the entire surface of the pedestal. Considering this integrated light-shielding structure as one unit, and connecting this unit longitudinally and laterally as shown in 2) of Fig. 13 and 2) of Fig. 19 to expand it to a predetermined size, a light-shielding structure with a vast area is formed. By doing so, a weed control effect can be exerted over a wide range. Also, regarding the flat tiles and the pedestal, since they are the same as those described in (1) and (2) of "Embodiments for Carrying Out the Invention", detailed description is omitted.

[0047] Embodiment 2: When constructing on sloping ground such as a hillside For the construction on the sloping ground of the slope I shown in 1) of Fig. 13, prepare a highly rigid square frame, determine the positions of the anchor bolts in advance for the sloping ground to be installed, drive them in, and fix the anchor bolts. Preferably, it may be as shown in 3) of Fig. 13, or it may be attached to driven-type anchor bolts in the concrete foundation work part 64.

[0048] For the pedestal 30 to be constructed on this slope I, use the one obtained by adding a pedestal to the pedestal of the present invention as shown in 2) of Fig. 13 and joining them by the joining method shown in 3) of Fig. 13, or welding joints may be made. The construction method after installing the pedestal is the same as that in paragraph 0012 of "Means for Solving the Problem", so it is omitted. By performing similar construction, a light-shielding structure along the inclined surface can be formed.

[0049] Also, when constructing on the slope J in 1) of Fig. 13, determine the position for installing the scaffold, embed the anchor bolts, and preferably fabricate the scaffold at a factory or the like. After fitting the flat tiles and the cut tiles processed obliquely onto the scaffold and confirming, disassemble them and reassemble them on-site to accurately and reliably form the light-shielding structure. This is because working on a slope is dangerous and it is not possible to immediately address problems such as defects, so it is more effective to carry out the work after prior preparation.

[0050] Here, for fabricating the scaffold of the slope J in 1) of Fig. 13, conduct the survey of the construction site, design the frame and the horizontal crossbars based on the horizontal plane and draw them. For example, as shown in 2) of Fig. 18 for the scaffold 40 of the slope J, with the frame 41 horizontal and taking the intersection point with the frame 42 as the reference point, if the intersection angle with the frame 43 is θ, the intersection angle with the frame 43 can be expressed as 90 - θ. Then, also draw the fastening hole parts, oblong hole parts and openings of the frame and the horizontal crossbars and perform the processing based on the drawing. Regarding the processing of the frame 41 and the horizontal crossbars 44, 45, 46 to be attached on the frames 42, 43 shown in 1) of Fig. 14, as shown in 2) of Fig. 18, since the intersection angle with the frame 41 is θ, based on the drawing, the right end faces of the horizontal crossbars 44, 45, 46 are cut at the cutting angle θ, and since the intersection angle between the frame 43 and the frame 41 is 90 - θ, the left end faces of the horizontal crossbars 44, 45, 46 are cut at the cutting angle 90 - θ.

[0051] Then, the function of fitting, clamping, and fixing the protrusions provided on the flat tiles, which is a feature of the pedestal of the present invention, is also applied to the pedestal used for this inclined surface. However, when the intersection angle between the frame and the horizontal bar is less than 90 degrees, as shown in (a) and (b) of Fig. 15, the right end surface of the horizontal bar 46 is cut so that it can move upward, and by lifting the horizontal bar upward until the end surfaces touch, the protrusion of the tile can be fitted into the opening of the horizontal bar. The length required for the lifting, as shown in 1) to 4) of Fig. 11, is such that the protrusion can be fitted when the thickness of the angle steel = t × 2 mm or more. Therefore, if the lifting distance is L2, since it can be obtained by 2 × t ≦ L2 = L1 / cosθ, if the horizontal bar is cut by an additional L1 ≧ 2 × t × cosθ mm from the surface cut at the cutting angle θ of the horizontal bar, the horizontal bar can be moved upward and the protrusion of the flat tile can be fitted into the opening of the horizontal bar. Also, from Fig. 15 (3), the left end surface of the horizontal bar does not interfere with the frame 43 even when the horizontal bar is lifted upward, so holes may be provided at the tightening positions obtained by on-machine calculations, but preferably, it is better to provide a long hole on the frame 43 to provide an adjustment margin.

[0052] For the construction of the inclined surface J in Fig. 13, the pedestal 40 in Fig. 14 is used. The pedestal 40 is composed of frames 41, 42, 43 and horizontal bars 44, 45, 46. On the plane of each frame, the cut tiles in the hatched part shown in 2) of Fig. 18 are used. In order to eliminate the rattling of the cut tiles when placing them, the backing plates 58 (hatched parts) shown in the respective arrow views in 2) to 4) of Fig. 14 are attached and screwed or welded to the same height as the plane of the horizontal bar. Preferably, although not shown in the figure of 1) of Fig. 14, it is even better to provide the backing plate 11 shown in Fig. 8 between the horizontal bars. Similarly, at the intersection of the frame 42 and the frame 43, as shown in the N-N cross-sectional view of 4) in Fig. 15, the backing plates 58 may be screwed or welded to the upper and lower parts of both frames.

[0053] The frame 42 that constitutes the stand needs to be provided with hole portions and long hole portions for tightening the horizontal bars. As shown in (a) and (i) of 2) in Fig. 15, tightening hole portions 48a and long hole portions 47a are provided, and tightening holes 48b and 47b are provided in the horizontal bars 44, 45, and 46. Also, as shown in 3) of Fig. 15, the frame 43 is provided with hole portions 48a and long hole portions 47a in a direction perpendicular (up and down) to the frame 41. A long hole may be provided within the range where the horizontal bar moves L2 mm from a predetermined position. Holes 47b and 48b for joining with the frame are provided at predetermined positions on the horizontal bar, and bolt joining is performed.

[0054] Next, the left end surface of the horizontal bar is cut at an angle (90 - θ) intersecting the frame 43 while considering the length. Since the horizontal bar will not hit the frame even when lifted, tightening holes 48a and 47a may be provided in the frame, and 48b and 47b may be provided at predetermined positions on the horizontal bar. Preferably, an adjustment margin may be considered as shown in (u) of 3) in Fig. 15, and long holes may be provided. After providing the horizontal bar on the frame, the frame and the horizontal bar are actually assembled to complete the stand.

[0055] Next, prepare the necessary number of flat tiles 13 for construction and the tiles for the cut tiles (hatched portion) shown in 2) of Fig. 18. First, fit the flat tiles into the stand 30, measure the dimensions of the empty spaces (where the cut tiles can be fitted), draw them, and cut the tiles according to the stand to produce the cut tiles. Next, put off the cut tiles without protrusions and assemble them from the lower part of the stand as per the procedure in Fig. 11. However, for the assembly of the topmost layer, it is preferable to loosen the tightening bolts of the frame 41, fit in the protrusions of the flat tiles, and then tighten again.

[0056] Next, when fitting the cut tiles without protrusions into the stand, apply an adhesive adhesive to the back surface and the outer peripheral surface of the tiles and fix them by fitting them in. Preferably, as shown in the cross-sectional view N - NN of 4) in Fig. 15, angle members are attached to the frames 42 and 43 and screwed to fix the tiles so that they do not peel off (fly off).

[0057] Regarding the construction on the inclined surface K of FIG. 13, survey the construction site and fabricate the gantry 50 shown in 1) of FIG. 17. As shown in 3) of FIG. 18, with reference to the frame 53 on the horizontal plane (bottom surface), draw a diagram with the intersection point with the frame 52 as the reference point. Also, if the intersection angle between the frame 51 and the frame 53 is θ1, machine the right end surfaces of the frame 53 and the cross bars 54 to 57 at the cutting angle θ1. As shown in (e) and (o) of FIG. 17, the length required to lift the frame should be t×2 mm or more in thickness of the angle steel, and since the protrusions can be fitted, if the lifting distance is L4 and the cutting length from the end surface at the angle θ1 is L3, then 2×t≦L4 = L3 / cosθ, so if the cross bar is further cut by L3≧2×t×cosθ mm from the surface cut at the cutting angle θ1, the cross bar can be moved upward and the protrusions of the flat tiles can be fitted into the openings of the cross bars.

[0058] When constructing on the inclined surface K of FIG. 13, with reference to the frame 53 shown in 3) of FIG. 18 along the bottom of the inclination, form the gantry 50 using the frames 51 and 52. Regarding the fabrication of this gantry, similar to the gantries fabricated on the inclined surfaces I and J of FIG. 13, machine it as shown in FIGS. 16 and 17 as the constituent members. The gantry fabrication procedure is to make the frame 52 and the frame 53 perpendicular in 1) of FIG. 17, align the frame 51 and the frame 53 at the angle θ1, fix them to the backing plate 58 shown in the O - O cross section of 1) of FIG. 17, and join them with bolts, washers, and nuts at each tightening hole. Also, in order to place the lifted tiles on the cross bars 54, 55, and 56 in the same way as the gantry 40, provide long hole portions in the direction perpendicular to the frame 53. Cut at the angle θ1 as shown in 2) of FIG. 17. Therefore, if the lifting distance is L4 and the cutting length is L3, then 2×t≦L4 = L3 / cosθ1, so if the cross bar is further cut by L3≧2×t×cosθ1 mm from the surface cut at the cutting angle θ1, the cross bar can be moved upward and the protrusions of the flat tiles can be fitted into the openings of the cross bars.

[0059] However, similar to the pedestal 40, for parts that cannot include protrusions with cut tiles, even at any angle on the back of the flat tile in Fig. 18, due to the relationship between the cutting line, the contour rib, and the trapezoidal rib, the surface of the flat tile and the back surface of the rib are parallel. Therefore, an adhesive with adhesiveness can be used on the pedestal and pasted and fixed so as not to come off the pedestal. Preferably, like (a) in 3) of Fig. 17, angle steel can be attached to the frame and the cross bars forming the pedestal to fix the tiles so that they do not fly off. Even when diagonal cutting of the tiles on the inclined surface is required as shown in Fig. 13, since the front and back of the flat tile are parallel planes, they can be placed on the frame and the cross bars without rattling at any part.

[0060] Embodiment 3: Slopes of public transportation facilities (roads, railways) In the construction at the location shown in 1) of Fig. 19, a large-scale shading structure can be formed by adding pedestals as needed as shown in 2) of Fig. 13 or 2) of Fig. 19. Since this is the same method as in Embodiment 2, it is omitted. However, another construction method is considered and will be described separately. For construction on a large area on a slope, it is preferable to manufacture the pedestal within the range that can be mounted on the truck bed at the factory, unitize it as a structure with flat tiles incorporated, and perform the installation work with heavy machinery on-site, so that the construction can be carried out safely and accurately, significantly shortening the time and reducing the cost, making it suitable for large-scale weed control construction work.

[0061] On the one hand, since the large-scale light-shielding structure constructed on the inclined surface has a flat surface and is an integrated light-shielding structure constructed on the gantry, for installation, it is preferable to perform foundation work with concrete at the construction site in advance, use JIS-standardized construction anchor bolts, and embed them. Also, at construction sites with a steep gradient and high altitude, as a means of preventing the risk of rainwater flowing rapidly over the surface of the tiles during heavy rain, an unequal-angle 66 is used on one of the horizontal bars shown in Figs. 20, 21, and 22 and welded to an equal-angle 65, a hole 61 is provided above the flat tile to allow rainwater to pass through gradually, and it can also serve as a foothold during construction to enable safe construction. Furthermore, as shown in Fig. 22, rainwater may be discharged by creating a groove that serves as a side gutter 62 at the joint between units. Also, by constructing a large light-shielding structure on the inclined portion, the loosening of the ground due to rainfall can be reduced, which is also effective in preventing the collapse of the slope.

[0062] When implementing the present invention, it is not limited to what is shown in the above embodiments, and various modifications can be made within the scope of the present invention according to the purpose and application. Materials, shapes, sizes, numbers, materials, etc. can be appropriately selected according to the application. As described above, Embodiment 1, Embodiment 2, and Embodiment 3 are weed control construction methods that utilize the characteristics of flat tiles and gantries. Regardless of the type of land or the type of sloping land, a light-shielding structure can be easily formed, creating an environment where plants cannot perform photosynthesis and ensuring that the weed control effect can be exerted.

Industrial Applicability

[0063] The "flat tile, pedestal, and its weed control construction method" of the present invention can be used for long-term countermeasures against weeds, dust, and sand in sloped areas, idle lands, uncultivated lands, road widening areas, and large-scale solar power generation facilities (megasolar) such as roads, railways, factories, and slopes around residences of public institutions. It can have a positive impact on industries such as exterior, civil engineering, and architecture, as well as the advertising industry that can use it as a billboard for publicity with the function of weed control, and individuals and small and medium-sized enterprises that make a living from this construction. In particular, the shipment volume of clay tiles in recent years is only about 10% of the peak in 1973, and it is still in a declining trend. Since the flat tile of the present invention is invented to be able to utilize clay materials for weed control purposes, it is considered to greatly contribute to the activation of the clay tile industry and the concrete tile industry.
