  However, when the roadside installation panel is made of a resin such as polycarbonate as in the above-mentioned Patent Document 1, various problems such as being melted by the high-temperature heat accompanying a vehicle fire or the like and falling to the private side, etc. May occur.

  On the other hand, by forming the roadside installation panel with glass as in Patent Document 2, it is possible to reduce the occurrence of problems such as melting and falling to the private side even when exposed to high temperature heat. However, as a result of intensive studies by the present inventors, when a laminated glass obtained by laminating a sheet glass and a normal sheet glass through an intermediate film is disposed as in Patent Document 2, it is damaged due to a vehicle collision or the like. In doing so, we found that there may be problems in terms of glass fragments scattered on the private side.

  Specifically, in consideration of preventing secondary disasters due to flying objects on the private side, it is desirable that the size of the glass fragments that are flying objects be as small as possible. However, the netted glass is low in strength and thus is more easily broken than the plate glass, and the glass fragments are likely to be large and heavy. Therefore, when the laminated glass is installed so that the meshed glass faces the private side as in Patent Document 2, a large and heavy lump of glass is scattered on the private side due to the breakage of the meshed glass. Therefore, there are concerns about secondary damage.

  Therefore, the present invention suppresses damage under the condition of being exposed to high-temperature heat due to a vehicle fire, etc., and even if it is damaged due to a collision or the like, a large and heavy scattered object is scattered on the private side. The purpose was to provide a panel for roadside installation that can be suppressed.

  The roadside installation panel of the present invention provided to solve the above-mentioned problems is a roadside installation panel installed on the side of the road, and the panel is bonded with a plurality of glass plates through an intermediate film. The combined composite glass is used as the main body, and among the glass plates, the roadside glass plate is the tempered glass.

  In the present invention, a road-side installation panel is constituted by a composite glass in which a plurality of glass plates are bonded together through an intermediate film so that the road-side glass plate is tempered glass. Thereby, the impact when the vehicle collides with the roadside installation panel can be firmly received in the tempered glass arranged on the roadside, and the breakage of the glass plate arranged on the private side can be minimized. . Therefore, according to the roadside installation panel of the present invention, it is possible to reduce the weight and size of the glass pieces scattered on the private side due to damage caused by a vehicle collision or the like, and to suppress the occurrence of secondary damage.

  Moreover, the roadside installation panel of the present invention is made of composite glass containing tempered glass, and tempered glass is arranged on the surface facing the roadside. Therefore, even if it is damaged under conditions exposed to high-temperature heat due to a vehicle fire, etc., it is possible to suppress collapse or formation of an opening, and as a result, sparks spread through the opening etc. Secondary damage can also be prevented.

  The roadside installation panel of the present invention can be installed on the side of any road, for example, a public road such as a general road or an expressway, a private road, a passage, or a road through which people and vehicles pass, or It can be suitably installed on a railroad bed or the like.

  Here, the tempered glass has a property of being pulverized to a small extent in accordance with breakage, as well as having a higher strength than a normal plate glass or the like.

Based on the knowledge described above, the roadside installation panel according to the present invention is such that the glass plate on the most private side among the glass plates constituting the composite glass is tempered glass .

  As in the present invention, in addition to the glass plate facing the road side, the glass plate facing the private side is also made of tempered glass, so that the fragments generated by the breakage of the private side glass plate (tempered glass) are reduced. Therefore, according to the present invention, when the roadside installation panel is damaged due to a vehicle collision or the like, the weight and size of the glass pieces scattered on the private side can be further reduced, and the occurrence of secondary damage is suppressed. The improvement of the effect can be expected.

The roadside installation panel of the present invention described above is such that, among the glass plates constituting the composite glass, the thickness of the most private side glass plate is equal to or less than the thickness of the most roadside glass plate .

  By setting it as this structure, when an impact acts on the roadside installation panel accompanying a vehicle collision or the like, the weight of the glass pieces scattered on the private side can be further suppressed.

  In the roadside installation panel of the present invention described above, it is desirable that the thickness of the most roadside tempered glass is 3 mm or more and 8 mm or less.

  By setting it as this structure, the required performance as impact resistance and intensity | strength in the road side tempered glass is securable. Thereby, it becomes possible to attenuate the impact caused by the collision of the vehicle or the like in the tempered glass on the road side and propagate it to the glass plate on the private side, and it is possible to suppress damage to the glass plate on the private side.

In the roadside installation panel of the present invention described above , it is preferable that the most private glass plate has a thickness of 4 mm or more and 5 mm or less .

  By adopting such a configuration, it is possible to ensure the required performance as impact resistance and strength for the glass plate on the private side. Thereby, the scattering amount of the glass piece to the private side accompanying the collision of a vehicle etc. can be suppressed to the minimum.

  ADVANTAGE OF THE INVENTION According to this invention, even if it is a case where it breaks with a collision etc., the panel for a roadside installation which can suppress that a big and heavy scattered matter scatters to a private side can be provided.

(A) is a perspective view which shows the installation state of the panel for roadside installation which concerns on one Embodiment of this invention, (b) is sectional drawing which shows the state which attached the composite glass to the frame. It is a perspective view which shows the state which fractured | ruptured the roadside installation panel which concerns on one Embodiment of this invention.

  Hereinafter, a roadside installation panel 1 according to an embodiment of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, the roadside installation panel 1 is installed on the side of the road R. The roadside installation panel 1 can be installed on the side of any road R such as a public road such as a so-called general road or a highway, a private road, a passage, a vehicle driving path in a parking lot, or a railroad bed. In this embodiment, the roadside installation panel 1 is formed of a composite glass 10 and a frame body 20 attached to the periphery.

  As shown in FIG. 2, the composite glass 10 is composed of composite glass (laminated glass) in which a private-side glass plate 12 and a road-side glass plate 14 are laminated and bonded via an intermediate film 16. The thickness d1 of the private-side glass plate 12 is preferably equal to or less than the thickness d2 of the road-side glass plate 14 (d1 ≦ d2). According to this, the size (weight) of the glass piece scattered on the private side can be minimized. Specifically, the thickness d1 of the private-side glass plate 12 is preferably 3 mm or more and 8 mm or less (3 mm ≦ d1 ≦ 8 mm), and more preferably 4 mm or more and 5 mm or less (4 mm ≦ d1 ≦ 5 mm). If the value is less than 3 mm, it cannot withstand wind loads when exposed to strong winds, and if it exceeds 8 mm, the amount of glass fragments when scattered is unfavorable. Further, when the area of the glass to be used is large, it tends to be broken when the thickness is thin. Therefore, the value is most preferably 4 mm or more and 5 mm or less. Moreover, it is preferable that the thickness d2 of the road side glass plate 14 is set to a thickness d1 or more of the private side glass plate 12 within a range of 3 mm or more and 8 mm or less (3 mm ≦ d2 ≦ 8 mm).

  The private side glass plate 12 is formed of a plate-like glass plate having translucency. As the private-side plate glass 12, non-tempered glass such as float glass, tempered glass obtained by a chemical tempering method or an air cooling tempering method, or the like can be used. Here, the non-tempered glass means one having zero internal strain. The private-side glass plate 12 may be made of non-tempered glass, but is more preferably made of tempered glass from the viewpoint of strength and small fragments generated at the time of breakage. In particular, tempered glass produced by the air-cooling tempering method is more preferable in terms of safety because fragments are shattered (because it is difficult to be sharp).

  The private-side glass plate 12 can be colored and translucent in addition to being colorless and transparent. In the present embodiment, a colorless and transparent one is adopted as the private-side glass plate 12. Moreover, considering that the outer surface of the private-side glass plate 12 is exposed to wind and rain, dust, etc., the outer surface can be treated with antifouling treatment, water repellent treatment, hydrophilic treatment, etc. It is. In addition, various surface treatments and the like can be performed in order to improve the absorption effect and the soundproofing effect of ultraviolet rays and infrared rays.

  The roadside glass plate 14 is made of tempered glass. As the tempered glass, tempered glass obtained by a chemical tempering method or an air-cooling tempering method can be used. In particular, the tempered glass by the air-cooling tempering method is preferably the same as the above-mentioned private-side glass 12. The road side glass plate 14 is colorless and transparent like the private side glass plate 12, but may be colored and have translucency. Moreover, since the surface of the roadside glass plate 14 is exposed to wind and rain, exhaust gas, dust, or the like, it can be subjected to antifouling treatment, water repellent treatment, hydrophilic treatment, or the like. . The roadside glass plate 14 can also be subjected to various surface treatments and the like in order to improve the absorption effect and the soundproofing effect of ultraviolet rays and infrared rays.

  The intermediate film 16 is a resin film interposed between the private-side glass plate 12 and the road-side glass plate 14. That is, the private-side glass plate 12 is attached to one surface of the intermediate film 16 by a technique such as adhesion or welding, and the road-side glass plate 14 is attached to the other surface of the intermediate film 16 by a technique such as adhesion or welding. It has been. The resin forming the intermediate film 16 may be an appropriate one such as a thermoplastic resin, a thermosetting resin, or an ultraviolet curable resin. Specific examples include vinyl polymers such as polyvinyl butyral (PVB). In addition, the intermediate film 16 can be made of a material that contributes to improving the absorption effect of ultraviolet rays and infrared rays, the soundproofing effect, and the like.

  The thickness of the interlayer film is not particularly limited, but is preferably 0.7 to 3.9 mm, and more preferably 1.5 to 3.1 mm. If the value is less than 0.7 mm, the glass is likely to be scattered upon impact, and if it exceeds 3.9 mm, it is not economically preferable.

  The composite glass 10 can be manufactured as follows, for example. That is, a sheet-like interlayer film material is placed on one of the private-side glass plate 12 and the road-side glass plate 14 and the other glass is overlaid thereon, and heated by a roll press method or the like. After pre-crimping with the method, the main pressure-bonding is performed in an autoclave of 1 to 12 atm and 120 to 160 ° C., and the private side glass plate 12 and the road side glass plate 14 are bonded with an intermediate film material, or the private side A gap is provided between the glass plate 12 and the roadside glass plate 14, a liquid ultraviolet curable composition is injected into the gap as an intermediate film material, and the intermediate film material is cured by irradiating ultraviolet rays to form the intermediate film. There is a method of forming and bonding the private side glass plate 12 and the road side glass plate 14.

  As shown in FIG. 1B, the roadside installation panel according to the present invention includes a composite glass 10 and a frame body 20 provided with a groove 22 into which the composite glass 10 can be fitted. The peripheral edge of the composite glass 10 is fitted into the groove 22 to form a panel. Although the composite glass 10 may be used as it is as a roadside installation panel, it is preferable to attach the frame body 20 to the periphery of the composite glass 10 in consideration of attachment workability, strength, and the like.

  The material forming the frame 20 is preferably made of metal in consideration of strength and the like, but is preferably made of aluminum or the like in order to prevent corrosion or the like.

  Next, the installation state of the roadside installation panel 1 will be described with reference to FIG. As shown in FIG. 1, the roadside installation panel 1 is installed on a support column erected along the road R in a state where the composite glass 10 is fitted into the frame body 20. The roadside installation panel 1 is installed in a state in which the composite glass 10 is fitted so that the private side glass plate 12 side faces the private land and the roadside glass plate 14 side faces the road R. The road side wall 30 can be configured by causing the roadside installation panel 1 stacked in the vertical direction between the above-described support columns to continue along the road R.

  By installing the roadside installation panel 1 as described above, even if a large impact is applied to the composite glass 10 due to a collision of a vehicle or a load, the impact is greatly attenuated in the roadside glass plate 14. (Absorbed). Therefore, the glass piece which generate | occur | produces by the failure | damage of the private side glass plate 12 turns into a small broken piece. Further, although the fragments of the roadside glass plate 14 are larger than the fragments of the private side glass plate 12, they are generated on the side of the road R through the intermediate film 16, and thus are hardly scattered on the private side. Further, since the fragments of the private side glass plate 12 are small and light, the amount of scattering of the glass piece is minimized due to the influence of the adhesive force acting between the private side glass plate 12 and the intermediate film 16. It is assumed that it can be suppressed. Therefore, according to the composite glass 10, even when the vehicle is damaged due to a collision or the like, it is possible to suppress the occurrence of secondary damage due to the scattering of a large and heavy lump of glass pieces on the private side. Moreover, the composite glass 10 is used for the roadside installation panel 1. Therefore, even when the vehicle is damaged in a situation where it is exposed to high temperature heat due to a vehicle fire or the like, the composite glass 10 can be prevented from collapsing or the composite glass 10 can be prevented from forming an opening. Secondary damage, such as the invasion of sparks through a part or the like and the spread of fire, can also be prevented.

  As described above, when not only the roadside glass plate 14 but also the private side glass plate 12 is made of tempered glass, the fragments generated by the damage of the private side glass plate 12 are also reduced. Therefore, by making both the private side glass plate 12 and the road side glass plate 14 made of tempered glass, the weight and size of the glass pieces scattered on the private side can be further reduced, and the effect of suppressing the occurrence of secondary damage. Improvement is expected.

  In addition, by setting the thickness d1 of the private side glass plate 12 of the composite glass 10 to be equal to or less than the thickness d2 of the road side glass plate 14, when an impact is applied due to a vehicle collision or the like, it is scattered to the private side. The weight of the glass piece can be minimized.

  Further, the composite glass 10 employs a glass plate 12 having a thickness d1 of 3 mm or more and 8 mm or less as a private side glass plate 12, and an impact resistance by adopting a glass plate 14 having a thickness d2 of 3 mm or more and 8 mm or less. It is possible to minimize the weight of the glass pieces scattered on the private side at the time of breakage while ensuring the necessary performance as a roadside installation panel such as property or strength more reliably.

  Hereinafter, the impact test results performed on A to E corresponding to the composite glass 10 used for the roadside installation panel 1 and the samples F and G prepared for comparison will be described. Samples A to G are attached to the frame body 20 whose lower end is arranged at a road surface height of about 1 m, and a 300 kg iron ball (with protrusions) is hit from the road side glass plate 14 side to the center position of the panel. A pendulum type impact was applied from a height of 95 cm in the vertical direction from the position, and the weight of the glass pieces scattered when the iron ball was struck and damaged was measured, and the largest one was recorded. Samples A to E are installed so that the tempered glass (corresponding to the roadside glass plate 14) faces the front side (corresponding to the road R side) on which the iron balls collide. Among these, for samples A to C, the private side glass plate 12 facing the back side (corresponding to the private side) is a plate glass (non-tempered glass), and for samples D and E, the private side glass plate 12 is used. Tempered glass. Samples F and G prepared as comparative examples are installed so that the glass sheet (non-tempered glass) faces the front side (corresponding to the road R side) and the tempered glass faces the rear side (corresponding to the private side). It is a thing. Table 1 below shows the thicknesses d1 and d2 of the tempered glass and plate glass (non-tempered glass) used in Samples A to G, and the test results.

  According to the test results in Table 1 above, for samples A to E in which tempered glass is arranged on the iron ball collision side (road R side), plate glass (non-tempered glass) is arranged on the iron ball collision side (road R side). It was found that the maximum weight of the glass pieces scattered as a whole was smaller than the samples F and G. Moreover, among samples A to E, samples D and E in which the glass plate on the back side (private side) is tempered glass are glass pieces scattered more than samples A to C in which the glass plate on the back side is plate glass. It has been found that the maximum weight is even smaller. Thereby, the maximum weight of the scattered glass piece can be suppressed by making the road R side tempered glass, and not only the road R side glass plate but also the private side glass plate is made of tempered glass. It has been found that the maximum weight of the glass pieces scattered can be suppressed.

  Further, for samples A to C in which the road R side is tempered glass and the private side is plate glass, the thickness d1 of the glass plate arranged on the private side and the thickness d2 of the glass plate arranged on the road R side Considering the effect of the relationship on the maximum weight of the scattered glass, the sample B having a relationship of d2> d1 has a maximum weight compared to the samples A and C having the same thicknesses d1 and d2. It turned out to be smaller. In the case where the same examination is performed on the samples D and E using both the road R side and the private side as tempered glass, the relationship is d2> d1 compared to the sample D in which both the thicknesses d1 and d2 are the same. Sample E was found to have a lower maximum weight. By combining the thickness d1 of the glass plate arranged on the private land side and the thickness d2 of the glass plate arranged on the road R side so as to satisfy the relationship of d2> d1, the glass that scatters with breakage It has been found that the maximum weight of the piece can be suppressed.

  The roadside installation panel of the present invention can be suitably used by installing it on public roads such as ordinary roads or highways, private roads, passages, parking lots, and other roads where people and vehicles pass, or on the railroad bed. is there.
