Description

  The present invention relates to a geometric pattern cutting method for cutting a design geometric pattern on a paved surface on which paving has been completed or an existing paved surface that is already shared.

  Conventionally, as a method of applying a pattern to the pavement surface, when asphalt pavement or concrete pavement is constructed, a mold for applying the pattern to the pavement surface is pressed, and the pavement surface is applied with cobblestone, block, or brick patterns. (See Patent Literature 1, Non-Patent Literature 1, and Non-Patent Literature 2).

  However, in the above-described conventional method, when a new asphalt pavement or concrete pavement is provided, it is necessary to press a mold for applying a pattern before the pavement is cured. In other words, as a series of work in the new construction work of the pavement, it is necessary to apply a pattern to the pavement surface by pressing the mold on the pavement surface before it is cured. There was a problem that the pavement surface of the existing pavement could no longer be patterned.

  In general, block pavement requires a lot of human labor in laying the block, and the cost of the block itself is higher than that of asphalt compound material or concrete material. Cost is high. Therefore, in the past, in response to the need to create a patterned pavement surface, the existing pavement was removed and a new pavement was newly installed, and construction by embossing as described above, or the existing pavement was There was no choice but to choose one of the methods of removing and building new block pavement etc. at high cost.

(A) And (b) is drawing explaining the visual effect at the time of making it incline with respect to the pavement surface in the cutting cross section of this invention, and cutting.

  Hereinafter, a method for cutting a design geometric pattern on a pavement surface according to an embodiment of the present invention will be described with reference to the drawings.

(Designed geometric pattern on the pavement surface)
As shown in the flow of FIG. 1, prior to cutting the pavement surface 2, a design geometric pattern is printed on the pavement surface 2. Ink-out can be performed not only by a method using an ink pot, but also by a method using a free ruler or a compass, or a method of projecting a projection image or laser light onto the pavement surface 2. In other words, any method may be used for inking as long as the cutting position can be specified when cutting a geometric pattern.

  Further, when cutting the geometric pattern on the pavement surface 2, it is not always necessary to print out the ink. That is, it is only necessary that the cutting cutter 5 can cut along a desired geometric pattern. For example, a jig such as a rail or a ruler for guiding the cutting cutter 5 can be used so as to cut the geometric pattern. is there.

  Furthermore, a driving means for moving the cutting cutter 5 while cutting is provided, and the geometric pattern is cut by the cutting cutter 5 moved by the driving means by automatically or manually controlling the driving means. Is also possible. Note that according to the above-described automatic control and cutting method, the geometric pattern can be cut by automatically and efficiently moving the cutting cutter 5 by program control corresponding to the desired geometric pattern.

  FIG. 2A is an example of a design geometric pattern by a curve. In this example, a plurality of arc patterns 1 are shifted and arranged to draw a ginkgo leaf pattern on the pavement surface 2. Furthermore, various patterns are drawn on the pavement surface 2 by changing the radius of the arc pattern 1. FIG. 2B is an example of a design geometric pattern by a combination of the curved pattern 3 and the linear pattern 4. FIGS. 2 (a) and 2 (b) each exemplify a part of the design geometric pattern, but various other design geometric patterns can be drawn on the pavement surface 2. Needless to say.

(Placement of cutting cutter on pavement surface)
As shown in FIG. 3 and FIG. 4, after marking the geometric pattern, the rotary blade 9 of the cutting cutter 5 is arranged on the pavement surface 2 in accordance with the geometric pattern marking line 11. The cutting method 5 is not particularly limited as long as it can cut the pavement surface 2. For example, a method of cutting the pavement surface 2 using water pressure, such as a water jet, can be used. Preferably, the cutting is performed with a rotary blade 9 provided with diamond. When cutting with the rotary blade 9, the cutting edge becomes smoother, and a corner portion 13 is formed between the pavement surface 2 and the cutting groove 12, and a sharp geometric pattern is formed on the pavement surface 2. Can be applied.

  The cutting cutter 5 is mainly composed of a traveling wheel 10 for traveling on the pavement surface 2, a rotary blade 9 for cutting, and a prime mover 7 (internal combustion type or electric type) that rotationally drives the cutting rotary blade 9. ) And an operation handle 6 for operating the traveling direction of the cutting cutter 5. The cutting cutter 5 includes a self-propelled type that runs while cutting at a predetermined speed, and a cutter that runs by a person's pushing force while cutting, and any type of cutting cutter 5 is used. It can be selected according to the construction situation as appropriate.

  When selecting the model of the cutter 5 for cutting, for cutting with an appropriate cutting ability according to the shape and size of the geometric pattern to be cut, the construction area, the cutting depth, the cutting width, the type of the paving body 14, etc. The cutter 5 is selected.

  The rotary blade 9 for cutting is appropriately selected according to the depth and groove width of the cutting groove 12 when the pavement surface 2 is cut. In particular, by using a plurality of rotary blades 9 as a groove width adjustment method, cutting with an arbitrary groove width is possible. However, due to problems such as the rotational drive capability of the rotary blade 9 and the cooling efficiency at the time of cutting the rotary blade 9, there is a limit to the groove width that can be cut by a single cut. By repeating, it is possible to cut the pavement surface 2 with a desired groove width.

(Pavement surface cutting)
When cutting a design geometric pattern using the cutting cutter 5, in addition to a geometric pattern by a straight line, a geometric pattern by a curve, cutting various geometric patterns by combining a curve and a straight line Is possible.

  When cutting a curved shape using the cutting cutter 5, the minimum radius is about 200 mm, but there is no particular upper limit. Since the minimum radius of the curve depends on the size and function of the cutting cutter 5 and the size of the rotary blade 9 attached to the cutting cutter 5, the size of the cutting cutter 5 and the rotary blade 9 is large. It is also possible to cut a curve having a radius smaller than the minimum radius by appropriately selecting.

  As another method of cutting a curve smaller than the minimum radius, it is also possible to perform cutting using a hand gutter to which a hand-held small-diameter rotary blade is attached.

  The optimum cutting groove width of the geometric pattern is 5 to 20 mm, and the optimum cutting groove depth is 5 to 50 mm. However, the cutting groove width and the cutting groove depth are not limited thereto, and the pavement 14 has Considering the cross-sectional configuration, the material of the paved body 14, the geometric dimensions of the geometric pattern, the use of the paved surface (for example, whether it is a roadway or sidewalk, heavy traffic or light traffic, etc.) It is possible to cut by setting the groove depth.

  Further, the cutting groove width and the cutting groove depth of the geometric pattern do not necessarily have to be constant, and it is possible to configure the cutting groove width and the cutting groove depth to be different in a part of the geometric pattern. As a result, various contrasts can be expressed in the geometric pattern cut on the pavement surface 2, and more complicated and diverse geometric patterns can be applied to the pavement surface 2.

  The pavement surface 2 to be cut of the design geometric pattern can be applied to the pavement surface 2 of various pavement bodies 14, for example, asphalt pavement (fine grain size, dense grain size, coarse grain size, open grain size), Colored asphalt pavement, concrete pavement, semi-flexible pavement, block pavement, earth-based pavement, water retentive pavement, heat-shielding pavement, etc. It is possible to cut the pattern.

  When cutting the pavement surface 2, the timing of cutting is particularly important. For example, when cutting the pavement surface 2 of asphalt pavement, after the pavement 14 is constructed, the cutting may be performed after a period of about two weeks. This is because if the pavement 14 is not cut after ensuring a stable strength, the aggregate will be scattered during the cutting, and the aesthetic appearance of the cut cross section and the geometric pattern itself will be impaired.

  Moreover, when cutting the pavement surface 2 of concrete pavement, it is good to cut after confirming the expression of a predetermined concrete strength after the construction of the pavement 14. As in the case of the asphalt pavement, if the pavement 14 is not cut after ensuring a stable strength, the aggregate will scatter during the cutting, and the aesthetic appearance of the cut cross section and the geometric pattern itself will be impaired. Because it becomes.

  Various visual effects can be expected depending on the type of the pavement 13 to which the design geometric pattern is applied. For example, the surface of the pavement other than the cutting groove 12 and the cutting portion is obtained by cutting a design geometric pattern on the pavement 14 containing the pigment or the pavement surface 2 of the pavement 14 colored on the pavement surface 2. Due to the contrast with 2, a clearer geometric pattern can be applied to the pavement surface 2.

  Furthermore, when limestone is used as the aggregate of the pavement 14, the cutting grooves 12 appear brighter than when ordinary crushed aggregate is used, and a clearer geometric pattern can be raised on the pavement surface 2. It is.

  Moreover, it is possible to apply geometric patterns according to more variations to the pavement surface 2 by applying or filling the cutting groove 12 with a single color or a plurality of color materials (including colored cement milk). .

  When cutting is performed with a rotary blade 9 provided with diamond, a corner portion 13 is formed between the pavement surface 2 and the cutting portion 12 as shown in FIG. 4A. However, such a corner 13 may be chipped or crushed due to the passage of a vehicle or a pedestrian. In order to suppress such an event, the chamfered portion 15 may be formed as shown in FIG.

  When the pavement surface 2 is cut, it is basically cut by the cutting cutter 5 in a direction perpendicular to the pavement surface 2, but it is also possible to cut in an oblique direction with respect to the pavement surface 2.

  For example, as shown in FIG. 5A, when the pavement surface 2 is cut so as to have a groove direction Vd that forms an acute angle with respect to the traveling direction Hd of the vehicle or pedestrian, a shade 16 is generated in the cutting groove 12. It becomes possible. That is, when the cutting groove 12 is viewed from the line of sight 17 of the driver or pedestrian of the vehicle, the shading 16 is generated in the cutting groove 12, so that the cutting groove is more than when cutting perpendicular to the pavement surface 2. 12 appears blacker and the pavement surface 2 around the cutting groove 12 appears brighter due to the reflected light 18 from sunlight. Thereby, the driver | operator and pedestrian of a vehicle can visually recognize the cut geometric pattern more clearly.

  Furthermore, with such a configuration, the geometric pattern is clearly visible only to those who are traveling or walking in the traveling direction Hd, and it is difficult for those who are traveling or walking from the opposite direction to be visually recognizable. Can be made. Thereby, for example, different geometric patterns can be visually recognized according to the driver or pedestrian of the vehicle to be visually recognized.

(Cutting groove end treatment and cleaning)
When the cutting by the cutting cutter 5 is finished, a portion where there was a portion that could not be cut by the cutting cutter 5 is cut using a hand cutter or the like. When all the cutting operations are completed, the cleaning operation is performed.

(Open traffic)
Once the design geometric pattern has been cut and the cleaning work is completed, the traffic restriction for the work is released, and vehicles and pedestrians can pass.

  As mentioned above, although embodiment of this invention was described based on drawing, a specific structure is not limited to these embodiment. The scope of the present invention is shown not by the above description of the embodiments but by the scope of claims for patent, and further includes all modifications within the meaning and scope equivalent to the scope of claims for patent.

  In the said embodiment, although the method of cutting a design geometric pattern on pavement surfaces, such as a road, was described, this invention is not limited to this, It can apply also to various structures.

  For example, the present invention can be applied to wall surfaces of building structures and civil engineering structures as long as the structural strength is not greatly affected. The cutting cutter may be configured such that the wall surface can be moved by suspending or using a dedicated jig, and the designed geometric pattern may be cut on the wall surface.

  In addition, the geometric pattern of the present invention can be used in a wide range of facilities such as indoor and outdoor pool facilities, stadium facilities, park facilities, airport facilities, port facilities, parking facilities, and factory facilities, regardless of whether vehicles or pedestrians come and go. This cutting method is applicable.

  As yet another embodiment, the character information can be cut and applied instead of the geometric pattern. According to such a method, character information disappears due to wear caused by running of a vehicle or walking of a pedestrian compared to a method of displaying character information on a pavement surface using a conventional paint or a neat method. It is possible to significantly suppress the display of extremely durable character information on the pavement surface.
