Description

The present invention relates to a frame structure of a light-transmitting panel that is installed along a road or railroad, prevents the propagation of noise, has light-transmitting properties, and allows visibility from the inside to the outside. The present invention relates to a frame structure of a light-transmitting panel capable of preventing an accident in which a melted material flows out even when the melted material melts.

Conventionally, sound insulation walls are installed along roads and railways to prevent the propagation of noise generated by vehicles such as automobiles and trains. Also known as such a sound insulation wall is a sound insulation wall in which translucent panels such as resin glass or inorganic glass are fitted so that the outside can be seen from the inside of the wall on which a vehicle or the like is running. ing.

However, as shown in FIG. 15, in the frame structure of the conventional translucent panel, the upper surface of the lower frame is flat. Therefore, as shown in FIG. 16, when the light-transmitting panel is burned and the light-transmitting plate is melted, the melted material is outside (outside of civil engineering structures such as bridges) across the light-transmitting panel on roads and railways. There was a problem that it could flow out or fall on the side that does not face the private land (generally the side that will become private land, hereinafter the same), causing personal injury or spreading fire to buildings in private land.

For example, in Patent Document 1, the thickness of the translucent panel 2 in a sound insulation wall in which the lateral ends of a translucent panel 2 made of synthetic resin are supported and the vertical ends are defined by horizontal members 3 Along the vicinity of the directional surface, a panel-burning fall prevention device 4 made of a refractory wire 5 supported by a vertical member 1 and a horizontal member in the vicinity of the translucent panel 2 is attached. A light-type sound insulation wall is disclosed (see claim 1 of the scope of claim of patent document 1, paragraphs [0011] to [0026] of the specification, FIG. 8 of the drawings, etc.).

However, the translucent sound insulation wall described in Patent Literature 1 has a refractory line to prevent the translucent panel 2 softened by the heat of the fire from falling outside (private land side) in the event of a fire caused by a vehicle accident or the like. The object (wire rope) 5 is used to catch the object. For this reason, it is not possible to reliably prevent the melted material of the translucent panel 2 made of a resin panel or the like from flowing out to the outside (the side of the private land) and inflicting human damage on people passing below. rice field.

Further, Patent Document 2 discloses a panel including a faceplate having sound insulation properties and at least a lower frame member for supporting the faceplate, and a rainwater receiver for receiving rainwater flowing down the surface of the faceplate on the upper surface of the lower frame member. A soundproof panel in which grooves are formed is disclosed (see claim 2 of patent document 2, paragraphs [0016] to [0023] of the specification, FIGS. 2 and 3 of the drawings, etc.).

However, the soundproof panel described in Patent Document 2 is mainly intended to perform self-cleaning by providing a photocatalyst-containing layer on the surface of the lower frame material, and the light-transmitting plate (light-transmitting panel) is burned. It was not envisaged to receive dissolved lysate. In other words, no consideration has been given to preventing accidents in which the light panel burns due to the aforementioned vehicle accident or the like, and the light-transmitting plate is melted and the melted material flows out to the outside. In addition, the narrow rainwater receiving groove 11, which does not consider these factors, could not receive the highly viscous melted material of the light-transmitting plate and prevent it from flowing out.
