Description

Construction equipment for road marking and non-slip surface pavement, and method for construction of road marking and non-slip surface pavement using the device. (EXECUTION MACHINE FOR ROAD MARKING AND ANTI-SKID PAVEMENT, AND EXECUTION METHOD OF ROAD MARKING AND ANTI-SKID PAVEMENT USING THEREOF}

The present invention relates to a road marking and a non-slip surface pavement that is visible at rainy nights and has an anti-slip effect, and in particular, a construction apparatus capable of efficiently constructing a pavement marking and a non-slip surface pavement having excellent aesthetic appearance and The present invention relates to a method of constructing a road marking and a non-slip surface pavement using a device.

Background Art Conventionally, surface packaging for road marking or slipping is installed on asphalt surfaces or concrete surfaces such as roads and parking lots for road safety.

These road markings and non-slip surface packaging (hereinafter referred to as non-slip surface pavement) are required to improve night visibility in road marking, for example, in order to exhibit their functions more. In packaging, the improvement of the larger slipper effect is calculated | required. And all of these methods tend to cope with the mixing of aggregates having a relatively large particle size in the coating, but according to the change in the coating properties according to the improvement of the function, the construction apparatus and the construction method have been required to develop a method suitable for it. have.

In view of the evaluation and practicality of the apparatus itself, among the various construction apparatuses, what is called a screw method can be practically evaluated. However, even with this apparatus, aggregates having an increased particle size as described above can be used. If mixed paints are used, there is a problem to be solved.

Specifically, when a high viscosity paint is used, or when the edge plate and the film thickness adjusting plate are not sufficiently heated, as shown in Fig. 12, the road surface display RS 'shows the edge plate 11' and the film thickness adjusting plate. Because of contact with both sides of (10 '), the flow of the coating material P' is deteriorated due to these resistances, and this part may wave and roll, resulting in a poor finish with an uneven width.

In addition, since the surface of the coating material P 'is actively flattened by the film thickness adjusting plate 10', the anti-slip effect cannot be sufficiently obtained.

In addition, in the case of coating on the surface of the road surface display RS '(hereinafter referred to as the remaining paint EP'), which is worn out by friction with the tire of the vehicle and needs repair, the portion (a) of FIG. As shown in the figure, aggregate B 'in the coating material P' is caught between the lower end of the hopper 7 'and the remaining paint EP'. In other words, the distance between the construction surface and the lower end of the hopper 7 'is set by the edge plate 11', but the edge plate 11 'is in contact with the road surface GL' in a state over the remaining paint EP '. Therefore, the gap between the lower end of the hopper 7 'and the remaining paint EP', which is the surface of the construction, is narrowed, and the aggregate B 'is expected to be caught by the aggregate B' in the paint P '. The construction of the road surface display RS 'cannot be performed.

In addition, in the construction of the non-slip surface packaging using the application device 1 'as described above, the next is likely to be inaccurate, and as shown in part (a) of FIG. 14, the edge is formed at the end of the preformed band AP. Since the plate 11 'contacts each other, the gap P is formed without the packaging material P being supplied to the portion of the edge plate 11'.

In order to solve the drawback of the surface pavement construction by such a screw method, conventionally, the strip | belt-shaped part AP formed in advance at equal intervals is formed as shown to part (b) of FIG. Construction is performed to fill it. However, because of the structure of the device, since the edge plate 11 'is positioned on the pre-formed band AP, the face surface of the pre-formed band AP is a reference construction and is formed in advance. The packaging material P applied between the strip | belt-shaped parts AP becomes thicker than the strip | belt-shaped part AP of the both sides previously formed, and produces a step | step.

In this context, the present applicant has already filed a patent application in Japan while devising an apparatus and method for solving these problems (Patent No. 9-279516, Patent Publication No. 9-279517, Patent Publication 2000). -54318), the above problem has already been solved.

However, new improvements are required to cope with the diversity of the field environment and to perform more rigorous construction.

Specifically, the construction apparatus 1 'for carrying out the above screwing method is a coating material placed in the hopper 7' by heating the slitter 5 'formed on the upper portion of the hopper 7' ( In the case of winter or cold conditions where the air temperature and the road surface temperature are lowered, the temperature of the paint P 'does not sufficiently increase, so that the viscosity is increased. As a result, the edge plate 11' is maintained. And the above problem due to the resistance of the film thickness adjusting plate 10 'becomes remarkable.

In addition, as shown in part (b) of FIG. 13, when the shutter 12 'is to be closed after the completion of construction, between the shutter 12' and the friction plate 70 ', or between the shutter 12' and the film thickness. Aggregate B ', debris thereof, or the like is sandwiched between the adjustment plates 10', and the shutter 12 'is not completely closed, and the pigment P' may leak from here. As a result, inadvertently contaminating the road surface GL 'or the road surface display RS' may require maintenance work or cleaning work, resulting in a decrease in the efficiency of construction work.

The present invention has been made in recognition of such a background, and the coating material does not leak out in a state in which the opening is closed, and stable construction can be performed even in a low temperature environment, thereby efficiently constructing road marking and non-slip surface pavement. The technical task is to develop a new road marking and non-slip surface paving device and a method of constructing a road marking and non-slip surface pavement using the device.

As the caking additive, a hot melt type (softening point 90 ° C. to 100 ° C.) petroleum resin is used as an example, but an appropriate type such as a solvent type, a multi-liquid reaction type, or a one-liquid reaction type may be selected. Moreover, vegetable oil, mineral oil, liquid synthetic rubber, etc. are used as a plasticizer. Moreover, calcium carbonate, tark, etc. are used as a filler. And as a pigment, the raw material according to predetermined coloring, such as titanium dioxide (white) and heat-resistant chrome yellow (yellow), is used.

The large particle diameter glass beads (G) are spherical materials made of glass, and in the road surface display (RS), those having a particle diameter of about 850 µm to 1500 µm are used, and in the non-slip surface pavement S, Use a 850 µm to 3000 µm sized one.

In addition, the small particle glass beads (GS) is a spherical material made of glass, and is a spherical material having a particle diameter of about 106 µm to 850 µm. These large-diameter glass beads G and small-diameter glass beads GS have a refractive index of about 1.9 to 2.5, which causes re-reflection when light arrives.

In addition, the small particle size glass beads GS may be adhered in advance to the large particle size glass beads G to be used as the composite glass beads.

In addition, as the aggregate (B), crushed materials such as rocks and fired products are used. In this embodiment, crushed products of ceramics are used as an example. As for aggregate B, the thing of particle size 500 micrometers-about 1500 micrometers is used for road surface display RS, and the thing of particle size 500 micrometers-about 3000 micrometers is used for anti-slip surface pavement S.

These large particle size glass beads (G), small particle size glass beads (GS) and aggregates (B) may be ones of suitable particle diameters. However, the construction apparatus 1 is provided with a road surface display RS and a film thickness adjusting plate 10. Since the film thickness of the anti-slip surface package S is determined, a larger diameter than the film thickness of the road surface display RS and the non-slip surface package S cannot be used.

In the construction site, the heat-melting paint (P) described above is usually heated and melted in advance by a melting furnace provided on a track rack, etc., and the construction device 1 is appropriately divided into small amounts to proceed with construction. Go.

Hereinafter, the construction method of newly applying the road markings (RS) to the road surface GL, such as asphalt, the construction method of applying the road markings (RS) to the remaining paint (EP), and the non-slip surface pavement (S) Each of them will be divided into construction methods and explained.

Embodiment 1

First, an embodiment of a coating method (normal hole) in which a road surface display RS is newly applied to a road surface GL such as asphalt is described.

In preparation of construction, for example, when a white line such as a centerline is drawn, marking is performed on the road surface GL, which is a construction surface, in advance, and a primer is dispersed. Subsequently, to the hopper 7 in the construction apparatus 1, the coating material P of the molten state which mixed the large particle size glass beads G and aggregate B from the melting furnace with which the track | base tray etc. were equipped is thrown in. At this time, the gas supplied from the gas cylinder 6 is burned by the burner heads 61 and 62, and the heat of the hopper 7 and the slitter 5 is heated to heat all the paints P in the hopper 7. Keep molten until all are used.

Particularly, since the edge plate 11 is larger in size than the area of contact with the coating material P in the molten state, the edge plate 11 is in contact with the outside air on the outer side. 11) acts as a heat sink, and as a result, the viscosity of the paint P may not increase sufficiently. However, according to the present invention, since the edge plates 11 are directly heated by the burner heads 63 and 64, a good molten state of the coating material P can be maintained, and the viscosity is not caused to rise.

Next, the state of the lower part of the hopper 7 which made the construction apparatus 1 facing the road surface GL which is a to-be-processed surface is shown to (a) part of FIG. In this state, the bottom surfaces of the two edge plates 11 respectively attached to the outer wall both sides of the opening 7H of the hopper 7 are in contact with the road surface GL. Then, when the shutter 12 is slid forward by the operation of the lever 9 and the opening portion 7H of the hopper 7 is opened, the paint P in the hopper 7 is discharged here and the road surface GL ).

And when the operator advances the construction apparatus 1 forward while holding down the handle 3 (pull | pulling), the coating material P is apply | coated to the road surface GL as shown to part (b) of FIG. In this application | coating, as for the coating material P, as shown in FIG. 3, the width dimension is decided by the two edge plates 11, and the thickness is determined by the film thickness adjusting plate 10. As shown in FIG.

At this time, the film thickness adjusting plate 10 is a structure for controlling the flow state of the paint P, and a surface perpendicular to the coating advancing direction of the paint contacting portion 10b is formed, and the film thickness adjusting portion 10a is coated. The length of the traveling direction is set to 30% to 400%, preferably 30% to 333%, more preferably 30% to 133% of the thickness of the road surface display RS after construction. For this reason, in the surface of the paint P, since the paint P is perpendicular | vertical to the paint-contacting part 10b, it becomes a resistance and the flow of this part is disturbed. Since the film P is determined by the film thickness adjusting section 10a in a state where the flow of the surface is confused, and the film P is released from the film thickness adjusting plate 10 in a short time, As shown in part d), the surface is roughened with irregularities.

In addition, the film thickness adjusting plate 10 is a structure for controlling the flow state of the paint P, and the paint contact portion 10b forms a slope in which the contact portion with the edge plate 11 faces upward on the edge plate 11 side. The film thickness adjusting portion 10a forms a slope in which the contact portion with the edge plate 11 faces rearward.

For this reason, as shown in FIG. 3, the coating material P is discharged | emitted from the hopper 7 smoothly at both ends of the film thickness adjusting plate 10, and the flow state deteriorates by the contact with the edge plate 11, 2, part (d) of FIG. 2 without forming a curve as if both ends of the coating material P, which are free from the film thickness adjusting plate 10 and the edge plate 11 and become free, are waved as a total. As shown in the figure, the straight line along the set width by the edge plate 11 is obtained.

Thereafter, as the construction apparatus 1 progresses, the spreader 8 is positioned on the paint P applied to the road surface GL, where the small particle glass beads GS are formed on the surface of the paint P. Evenly distributed. In time, the coating material P hardens with a temperature fall, and forms the center line which is an example of the road surface display RS.

When the construction of the road surface GL in the predetermined range ends, the shutter 12 is closed to close the opening 7H. At this time, according to the present invention, the contact portion between the closed end 70C of the friction plate 70 and the closed end 12C of the shutter 12 is configured to be in a line contact state, and in particular, the friction plate 70 Since the lower slope S70 at the bottom side is a slope falling downward from the side, the aggregate B, the large-diameter glass beads G, and these fragments can be avoided into the space at the front side, so that the shutter ( 12) and friction plate 70 can be avoided to engage them.

In addition, the aggregate B, the large-diameter glass beads G, and the fragments thereof can be avoided downward between the shutter 12 and the film thickness adjusting plate 10, and may be sandwiched between the shutter and the film thickness adjusting plate. none.

As a result, the opening 7H by the shutter 12 can be completely closed, and the leakage of the paint P can be prevented, and the road surface GL is not accidentally contaminated.

Embodiment 2

Next, the center line, which is an example of the road surface marking RS applied to the road surface GL such as asphalt, is worn by friction with the tires of the vehicle and the like, and the road surface marking RS (hereinafter referred to as residual paint EP) A description will be given of an embodiment of a construction method (repair construction) in which a road surface display (RS) is painted.

In addition, in the construction apparatus 1 used in this embodiment, the distance between the lower surface of the projection part 12a formed below the shutter 12, and the lower surface of the edge plate 11, especially at the time of maintenance and normal construction, is used. The road markings RS or the anti-slip surface pavement S are set so short that they can be applied with approximately the same thickness.

Hereinafter, a description will be given of the repair construction of the road surface display (RS) over the remaining paint (EP). In addition, since the overlapping part of the road surface marking RS also arises when new construction of a crosswalk is carried out, such a construction is also included in the category of repair construction.

First, in preparation for construction, the coating material P in the molten state is introduced into the hopper 7 in the construction apparatus 1 from the melting provided in the track carrier and the like. At this time, the gas supplied from the gas cylinder 6 is combusted by the gas burner 60, and the heat of the outer wall of the hopper 7 and the slitter 5 is heated to heat all the paints P in the hopper 7. Keep molten until all are used.

Next, the state of the lower part of the hopper 7 which made the construction apparatus 1 facing the remaining paint EP which is a to-be-processed surface is shown in FIG. In this state, the projection part 12a in the shutter 12 is located in contact with the remaining paint EP. In addition, the bottom surfaces of the two edge plates 11 are not in contact with the road surface GL, but the inner surface is in contact with the side surface of the remaining paint EP slightly.

Then, when the shutter 12 is slid forward by the operation of the lever 9 to open the opening 7H of the hopper 7, the paint P in the hopper 7 is discharged from the remaining paint ( EP).

And when the operator advances the construction apparatus 1 forward while holding down the handle 3 (pull), the paint P is applied onto the remaining paint EP as shown in Fig. 7B. do. In this coating, the coating material P has a width dimension determined by two edge plates 11 as shown in FIG. 8 and a thickness determined by the film thickness adjusting plate 10.

At this time, the shutter 12 constructs the distance between the film thickness adjusting unit 10a and the remaining paint EP, which is the surface to be treated, by forming the projection 12a on the road surface GL without the remaining paint EP. In this case, the bottom surface of the edge plate 11 can be kept almost the same as in normal construction in contact with the road surface GL. This prevents the aggregate (B), glass beads (G), etc. from being blocked between the remaining paint (EP) and the film thickness adjusting plate (10a), and at the same time, the surface of the aggregate (B) mixed on the remaining paint (EP). Marking RS can be constructed to a predetermined thickness.

Thereafter, as the construction apparatus 1 progresses, the spreader 8 is positioned on the paint P applied to the road surface GL, where the small particle glass beads GS are formed on the surface of the paint P. Evenly distributed. In time, the coating material P hardens with a temperature fall, and the center line which is an example of the road surface display RS is repaired.

Next, the raw material in a molten state is thrown into the hopper 7 in the construction apparatus 1. At this time, the gas supplied from the gas cylinder 6 is combusted by the gas burner 60, and the heat of the outer wall of the hopper 7 and the slitter 5 is heated to heat all the packaging materials P in the hopper 7. Keep molten until all are used.

Although not shown in this figure, it is in contact with the road surface GL.

Then, when the shutter 12 is slid forward by the operation of the lever 9 to open the opening portion 7H of the hopper 7, the packaging material P in the hopper 7 is discharged here and the road surface GL ).

And when an operator advances the construction apparatus 1 forward while holding down the handle 3 (pull | pulling), the packaging material P is apply | coated on the road surface GL. At this time, the width P of the packaging material P is determined by the two edge plates 11, and the thickness is determined by the film thickness adjusting plate 10.

Thereafter, as the construction apparatus 1 progresses, the spreader 8 is placed on the packaging material P applied to the road surface GL, where the small particle size glass beads GS are formed on the surface of the packaging material P. Evenly distributed.

At the time when the application of the packaging material P to one side of the scheduled city factory is finished, the shutter 12 is slid rearward by the operation of the lever 9, and the opening 7H of the hopper 7 is closed. The discharge of the packaging material P is stopped. Before long, the packaging material P applied to the road surface GL is cured with a decrease in temperature, and forms a part of the non-slip surface pavement S in a band shape as shown in part (b) of FIG. 10. In addition, the strip | belt-shaped part apply | coated to the road surface GL in this way is called strip | belt-shaped part AP previously formed.

Subsequently, the packaging material P is applied to an adjacent position of the previously formed strip portion AP. At this time, the slitter 5 is fitted to one edge of the previously formed strip portion AP, and the edge thereof is placed thereon. This is done without the plate 11L acting. Specifically, as shown in part (c) of FIG. 10 and part (b) of FIG. 9, in the state where the edge plate 11L is raised by the operation of the lever 13, the previously formed band-shaped part AP The construction device 1 is positioned at an adjacent position of the edge plate, wherein the raised edge plate 11L is located above the preformed strip portion AP, and the bottom surface of the edge plate 11R is in contact with the road surface GL.
