Description

Guard plate for protecting expected collision structure and Method for manufacturing the same}

The present invention relates to a collision prediction structure protector technology, and more particularly, by reflecting the product's visibility, safety, economical efficiency, and maintainability, preventing safety accidents due to roadside structure collisions, driver protection, and buffering role in collision prediction structure protectors and It relates to a manufacturing method thereof.

A general electric pole painted plate is made of a galvanized steel plate or aluminum plate with a thickness of about 0.3 mm. However, due to the nature of the material, no matter how well the cut part is processed, it causes a cut safety accident when it comes into contact with a pedestrian and/or a cyclist with a sharp edge, and the number of civil complaints continues to increase.

In addition, to prevent corrosion, an adhesive paint is applied to the painted plate, and the result of measurement for about 1,000 hours upon product delivery is the test report to determine whether the crack conditions such as discoloration or deterioration pass or not, and then it is laid on site. However, there is a disadvantage in that the discoloration and/or corrosion of the current paint plate is seriously progressed after 5 years of field experience according to the work performance.

This is very closely related to the increase in civil complaints and the increase in maintenance costs due to the deterioration of urban aesthetics. And the impact resistance test for existing products only checks the crack condition of the epidermis through the fall of any object on the steel plate itself, and there is no protective impact test on the material (electric pole, structure, etc.) surrounding the painted plate, and there is no internal structure There is a problem that there is no protection function for And, with respect to visibility, a rectangular surface having an area of about 110 mm in width and about 70 mm in length is attached to the upper and lower right corners through a reflective luminescent tape, respectively. However, depending on the low area, it is difficult for the driver to visually identify the driver at night, and the yellow and black backgrounds are attached to each half and half, which actually reduces visibility by half.

In the case of fixing the painted plate to the electric pole using a band and a clip, the band part itself is made of iron and is sharp, and the finished part protrudes, which also causes a pedestrian safety accident.

On the other hand, in the case of a sticker-type electric pole painting board, it is printed with a special ink that does not discolor or change on soft PVC (Poly Vinyl Chloride) with a thickness of about 0.3 mm, and an adhesive for cement is used as the adhesive material. Here, since the sticker-type adhesive is used, the rigidity of the attachment and vertical twisting will be slightly different depending on the skill of the operator, and the adhesive force is significantly lowered during reattachment due to a mistake during the first attachment, resulting in a peeling phenomenon. In addition, the special ink rapidly corrodes due to the external environment such as ultraviolet rays when time passes. As a result, maintenance costs increase and, due to the lack of a shock absorbing function, power outages and serious driver accidents increase during a vehicle collision.

On the other hand, in the case of an electric pole paint plate to prevent adhesion of advertisements, high-density polyethylene is used as a material. It is characterized by the fact that it is difficult to attach advertisements to the front surface of the painted sheet, and a horn-shaped protrusion is formed so that it can be easily removed. It is produced at a higher price than other products by making horn-shaped protrusions, and the economic feasibility of the product is significantly lowered because it has no functions other than to prevent the adhesion of advertisements.

In particular, when the horn-shaped protrusion is touched by hand, it is sharp and hard, so there is a high risk of a safety accident in case of a pedestrian collision. In addition, there is a disadvantage in that the occurrence of a serious accident in a vehicle collision is high because there is no expansion and contraction function.

Hereinafter, with reference to the accompanying drawings, a collision-prediction structure protector and a manufacturing method thereof according to an embodiment of the present invention will be described in detail.

1 is a plan view of a collision prediction structure protector 100 according to an embodiment of the present invention. Referring to FIG. 1 , the width is about 800 mm, the length is about 900 mm, and the thickness is about 2.2 mm to 3.5 mm. In general, the horizontal and vertical lengths of the existing paint plates are the same.

First, the arrangement of the design is sequentially arranged in the yellow area 110 and the black area 120 going from right to left. This is different from the diagonal arrangement of previous products, but it is clearly distinguished in visibility. In other words, in the case of the existing product, the number of yellow and black arrays is 7, but in the case of the present invention, 13 are arranged.

As the number of arrays increases, the structure identification through the structure arrangement with the difference between yellow and black contrast becomes more distinct. And, as a result of the experiment, making the width 120 of the black region larger than the width of the yellow region 110 makes the identification more distinct. This is the result of obtaining the optimal width and number of arrays through trial and error results.

In order for the driver to identify the structure best when entering the vehicle, the current structure protector starts with the yellow area 110 (about 40mm), then the black area 120 (about 70mm), and then the yellow area ( 130) (about 60mm). In other words, the width of the yellow region 110 may be 30-50 mm, the width of the black region 120 may be 60-80 mm, and the width of the yellow region 130 may be 50-70 mm. there is.

As a result, in the daytime, it is possible to clearly identify with the optimal arrangement of yellow and black, and at night, the yellow area 110 coated with a reflective luminous material is arranged at a position where the driver can identify it best.

Advertisement phrase 140 may be arranged in a red design so that the structure (eg, electric pole) to prevent the attachment of advertisements to the structure (eg, electric pole) induces awareness in advance and to take warning action. It shoots the dye in the form of spraying through the laser equipment, making it even clearer and simplifies the work process through automation.

◇ ◁의 모형으로 제작하고, 한장소는 노란색 바탕에 부착, 다른 장소는 검은색 바탕에 부착한 것이다. 부착결과 검은색 바탕에 반사 야광 스티커는 미관상 좋지 않고 한부분만 돋보이게 되어 통일된 보호구 역할을 하지 않았다. 노란색 바탕에 스티커 부착시 주간에는 스티커가 돋보이지 않았고, 특유의 노란, 검은색 배치만으로 시인성이 좋게 보였다. The reflective luminous sticker design (150) is ○ □

◇ It is made as a model of ◁, and one place is attached to a yellow background and the other place is attached to a black background. As a result of attachment, the reflective luminous sticker on a black background was not aesthetically pleasing and only one part stood out, so it did not play the role of a unified protective gear. When a sticker was attached on a yellow background, the sticker did not stand out during the day, and visibility was good only with the distinctive yellow and black arrangement.

And, there was more differentiation in visibility at night, and the yellow-based sticker showed a clear superiority in visibility than the black-based sticker arrangement. As for the design model, the ◇ model stood out the most.

As a result of placing diamond models only on the yellow background, the visibility was clearly good, in contrast to the existing product that invaded the yellow and black backgrounds in half and impaired visibility. In addition, it is possible to maximize the visibility by arranging a larger area of the sticker compared to the existing product.

2 is a cross-sectional view taken along the I-I axis of the collision-prediction structure protector 100 shown in FIG. 1 . Referring to FIG. 2 , a yellow region 110 and a black region 120 are coated on the surface of the plate 200 . The plate 200 has a wavy cross-section, and a protrusion 210 is formed on an inner curved surface opposite to the surface. A rounded rounding part 240 is formed at the end of the protrusion part 210 .

The protrusion 210 has various sizes, and a large protrusion is formed on the inner curved surface when the curved surface is large, and a small protrusion is formed when the curved surface is small. It was rounded to minimize resistance when wrapped around the structure and to facilitate contraction and relaxation in the event of a collision. In addition, although the number of protrusions 210 is three in the drawing, it is possible to increase the number to 3 to 6 according to site conditions. The connecting portion 220 is a connecting portion of yellow and black background, and the protrusion is lower than the protrusion 210 and arranged in 3 to 4 quantities. The joint 210 is a method in which small waves (that is, irregularities) are placed again on the surface of the large wave pattern model of the plate 200 itself. The joint portion 210 is useful for leaving advertisements attached, and has a structure that improves the feel and helps prevent pedestrian safety accidents by maintaining a certain degree of elasticity.

FIG. 3 is a view showing dimensions at each portion of the plate 200 shown in FIG. 2 . Referring to FIG. 3 , in the case of the yellow region 110 , the joint 321 is about 44.6 mm. In the case of the black region 120 , the joint 311 is about 56.7 mm. Connection 220 is about 14.4 mm. The connection part 220 has no wave shape.

FIG. 4 is a partially enlarged view of the yellow joint shown in FIG. 3 . Referring to FIG. 4 , the joint depth 411 is about 0.5 mm. In other words, the height between the inner curved surface and the ridge of the joint is 3.5 mm, and the height between the inner curved surface and the trough of the joint is 3 mm. Thus, 3.5mm-3mm is 0.5mm.

FIG. 5 is a partially enlarged view of the black joint shown in FIG. 3 . Referring to FIG. 5 , the thickness of the seam 511 entering the wave pattern is 2.5 mm, the primary thickness is 2.2 mm, and the secondary thickness is 0.3 mm (joints). The reason for the difference between the depth of the joint 411 and the thickness of the seam 511 is that it must be a model that covers the circular structure, so the protrusion section that requires expansion and contraction of the vehicle collision is thick in order for the entire model to be curved in a round shape. Although it is not, the section that is easy to bend in a round shape is slightly thinner and the thickness is modified to reconsider the convenience during construction. In other words, the connecting portion 220 having the seam 511 has a thinner thickness than the next portion. The material of the plate 200 is a mixture of a poly vinyl chloride (PVC) material and an acrylonitrile butadiene styrene (ABS) resin, which is a material strong in shock absorption. ABS (Acrylonitrile Butadiene Styrene) is an impact-resistant resin with stable mechanical properties and, in particular, strong resistance to heat and impact. As a result of the 208kN yield load test, the material mixed with the wave pattern and ABS material deformed only about 3.81mm.

6 is a view expressing the joint 230 shown in FIGS. 4 and 5 . Referring to FIG. 6 , the joint portion 230 represents the joint 620 and constitutes a convex wave pattern. And, the thickness 610 of the joint is about 0.3mm. The material of the joint 230 is ASA (Acrylic Styrene Acrylonitrile) resin, which prevents discoloration and does not corrode, as a main raw material.

7 is an enlarged view of the distal end of the anti-collision structure protection device 100 shown in FIG. 1 . Referring to FIG. 7 , the finishing part is rounded (R1), and since the material is soft to the touch, safety accidents can be prevented in advance.

8 is a front view of the connection band 800 according to an embodiment of the present invention. Referring to FIG. 8 , the fastening method is performed from the inside rather than the external fastening method. Therefore, the band is integrated. Fastening parts 810 and 820 are formed in the connection band 800, and the interval between the groove-shaped fastening parts is about 10 mm, so that fastening can be made firmly for each standard. In addition, the protruding jaw 840 is formed by using a plurality of fastening portions 810 and 820 as a unit.

9 is a view showing a form in which a fastening hole 911 for fastening is formed at the end 910 of the plate 200 constituting the anti-collision structure protector 100 shown in FIG. 1 . Referring to FIG. 9 , a fastening hole 911 is formed at the end 910 . The fastening hole 911 has a width of about 4.5 mm and has an inclination of about 13° 24' based on a straight line extending the peak of the distal end 910 .

10 is a view showing a state in which the end of the connection band 800 shown in FIG. 8 is fastened to the fastening hole 911 shown in FIG. 9 . Referring to FIG. 10 , it is not a method of fastening from the outside, but a method of fastening from the inside. Accordingly, the connecting band 800 is integrally formed.

As for the fastening method, one end of the connecting band 800 is pushed into the fastening hole 911, which is a section with a hole in the end, and fastened to the fastening hole 911 having an oblique line. Then, the other end of the opposite side is also pushed into the fastening hole 911 in the order of the previous step, and it is tightened by walking step by step. Since the fastening method has to be fastened by pushing from the outside, the fastening is facilitated by pressing the protruding jaw 840 part by hand. Since the outer diameter of the structure is different depending on the height and/or the fastening part of the structure, the band may also be lengthened or shortened. Therefore, the connection band 800 can be cut to an appropriate length before fastening.

11 and 12 are detailed grooves of the fastening hole 911 shown in FIG. 9 . 11 and 12, the groove spacing is about 10 mm, and the fastening angle in the oblique direction is set to about 60° to ensure fastening. As for the connecting band, about 2.5mm of the total thickness is PVC+ABS, and 0.3mm is composed of ASA resin.

13 is a conceptual diagram of a connection band 1300 according to another embodiment of the present invention. Referring to FIG. 13 , the teeth of the left band 1310 and the right band 1320 are configured to be opposite to each other. Here, two or more teeth 1311 are formed on the left band 1310 . The right band 1320 has a length sufficient to cover the outer diameter of the pole, and the teeth 1321 are manufactured at intervals of 10 mm. If the pole is small, it can be cut and used. Turn it over (the direction in which the structure and the sawtooth are facing each other) and fasten it on the opposite side. Then, the teeth of the left band 1310 and the right band 1320 are pulled together so that they are tightly fastened to each other. After that, it is finished by finishing processing through the fixing box 1330 . That is, in a state where the left band 1310 is on the upper side and the right band 1320 is engaged with each other on the lower side, the fixing box 1330 is inserted into this interlocked portion, and the piece is inserted and fixed by driving the piece.

14 is a view in which the collision-prediction structure protection device 100 shown in FIG. 1 and the connecting band 800 shown in FIG. 8 are fastened together. Referring to FIG. 14 , the arc length of the collision prediction structure protector 100 is about 800 mm, and the arc length of the connection band 800 is about 250 to 500 mm.

15 is a perspective view in which the collision prediction structure protection device 100 shown in FIG. 1 is fastened to the electric pole 1500 . Referring to FIG. 15 , the collision prediction structure protector 100 surrounds the outer peripheral surface of the electric pole 1500 and then the connection band 800 is fastened. A plurality of connection bands 800 are installed.

16 is a flowchart showing a process of manufacturing a collision-prediction structure protector according to an embodiment of the present invention. Referring to FIG. 16, first, a mixture of polyvinyl chloride (PVC) material and acrylonitrile butadiene styrene (ABS) resin is produced, injected into the mold, and heated to a melting point temperature to prepare a plate 200 (step S1610). At this time, PVC is 60 ~ 90 wt%, ABS is 10 ~ 40%. Here, wt is the weight. In addition, the melting point temperature is 140 ~ 200 ℃. Of course, the corrugated shape of the entire outer appearance and the corrugated shape forming the joint are formed in advance in the mold.

When the plate 200 is completed, the coating process is simultaneously performed using the ASA resin (black, yellow) multi-color extrusion method at the same temperature as a secondary operation inside the same mold (step S1620). For this multi-color extrusion method, since it is disclosed in Patent Registration No. 10-2062334 (title of the invention: separate extrusion mold apparatus), a more detailed description will be omitted for a clear understanding of the present invention.

Thereafter, the completed model is cooled through a water channel (step S1630). At this time, after cooling the inlet temperature of the cooling water (10~15℃), the hot water after the outlet temperature (22~25℃) goes through a cooler again, cools it again, and then flows in again.

Thereafter, the reflective tape is applied to the attachment portion of the model to adhere to the heat (step S1640). In other words, the reflective tape coated on the yellow area (110, 130 in FIG. 1) is attached to it by applying heat.

Thereafter, the words "Do not attach dangerous advertisements" are engraved with a laser printer in the central yellow area (step S1650).

Thereafter, the length of the product is cut to 900mm, and a fastening hole for connecting the connecting band 800 is created and shipped as a perforation (step S1670).
